The large convex hull 2 is used for accommodating a body of an electronic product, and the small convex hull 3 is used for accommodating pins of the electronic product so as to protect the pins.
In a workshop, the specific production method for producing the carrier band pup joint comprises the following steps:
s1, taking out a flat belt 4 shown in fig. 4 by a worker, putting the flat belt 4 on the top surface of a heating plate, and heating the flat belt 4 through the heating plate to soften the flat belt 4;
S2, a worker lays the flat belt 4 on the top surface of the concave die plate A5 of the first pair of dies, so that the flat belt 4 covers all forming grooves 6 in the concave die plate A5, as shown in FIG. 5; then, the male die of the first auxiliary die is controlled to move downwards, and the male die drives a plurality of forming blocks 7 on the male die to synchronously move downwards, so that each forming block 7 is respectively matched with each forming groove 6, as shown in fig. 6, and a large convex hull 2 is formed on the flat belt 4, and the structure of the flat belt 4 with the large convex hull 2 is shown in fig. 7;
S3, taking away the flat belt 4 with the large convex hulls 2 by workers, and then placing the flat belt 4 on the top surface of a concave die plate B8 of a second auxiliary die, so as to ensure that each large convex hull 2 on the flat belt 4 is respectively covered over each blind groove 9 in the concave die plate B8, as shown in FIG. 8; then, the male die of the second auxiliary die is controlled to move downwards, the male die drives a plurality of compression bars 10 on the male die to move downwards, the compression bars 10 downwards squeeze the bottom material of the large convex hull 2, and after each compression bar 10 is respectively matched with each blind groove 9, as shown in fig. 9, the small convex hull 3 is formed at the bottom of the large convex hull 2, and then the required carrier band pup joint is produced;
s4, taking away the carrier band pup joint: the worker pulls up the carrier band nipple to remove the carrier band nipple from the female die plate B8 in the direction indicated by the arrow in fig. 10, thereby obtaining a first carrier band nipple;
S5, the worker repeats the operations of the steps S1-S4 for a plurality of times, and a plurality of carrier band pup joints can be continuously produced.

II. In step S4, when the worker pulls out the carrier band nipple from the female die plate B8, since the small convex hull 3 of the carrier band nipple is also embedded in the blind groove 9 of the female die plate B8, the small convex hull 3 is distorted and deformed [ but the small convex hull 3 is not deformed in terms of process, thereby reducing the production quality of the carrier band nipple). In addition, the carrier band pup joint is required to be pulled out manually, which clearly further increases the production time of the carrier band pup joint and further reduces the production efficiency of the carrier band pup joint.
Therefore, a production device and a method for greatly improving the production efficiency and the production quality of the carrier band pup joint are needed.

S45, controlling a piston rod of a third cylinder 32 of the material taking mechanism 19 to retract upwards, driving a vacuum disc 33 to move upwards, driving a first suction head 35, a second suction head 36 and a third suction head 37 to synchronously move upwards by the vacuum disc 33, and further driving a carrier band body 1, a large convex hull 2 and a small convex hull 3 of a carrier band pup joint to synchronously move upwards, so that the carrier band pup joint is taken out from a strip-shaped carrier 15, and the structure of the taken-out carrier band pup joint is shown in fig. 37, and the structure of the taken-out carrier band pup joint is shown in fig. 1-3;
S46, controlling a stepping motor B16 to start, wherein the stepping motor B16 drives a main shaft 17 to rotate, the main shaft 17 drives a rotary table 18 to rotate, the rotary table 18 drives a material taking mechanism 19 and a heating and forming mechanism 20 to synchronously rotate, and when the material taking mechanism 19 rotates 180 degrees, the carrier band pup joint just moves to be right above a material collecting table 38;
S47, controlling the vacuum pump 34 to be closed, and enabling the carrier band pup joint not to be adsorbed any more, wherein at the moment, the carrier band pup joint falls on the material receiving table 38, and the falling direction of the carrier band pup joint is shown by an arrow in FIG. 37, so that material receiving of the carrier band pup joint is realized;
S5, the worker repeats the operations of the steps S1-S4 for a plurality of times, and a plurality of carrier band pup joints can be continuously produced.
As can be seen from steps S43 to S45, a worker only needs to control the piston rod of the third cylinder 32 of the material taking mechanism 19 to extend downwards, so that the first suction head 35, the second suction head 36 and the third suction head 37 are respectively contacted with the top surface of the carrier body 1 of the carrier nipple, the bottom surface of the large convex hull 2 and the bottom surface of the small convex hull 3; then, the vacuum pump 34 is controlled to be started, so that the carrier tape body 1, the large convex hull 2 and the small convex hull 3 of the carrier tape pup joint are respectively adsorbed and fixed on the first suction head 35, the second suction head 36 and the third suction head 37; finally, the piston rod of the third cylinder 32 is controlled to retract upwards, so that the first suction head 35, the second suction head 36 and the third suction head 37 synchronously upwards, and the carrier band body 1, the large convex hull 2 and the small convex hull 3 of the carrier band pup joint are driven to synchronously upwards move, and the carrier band pup joint is taken away from the strip-shaped carrier table 15.
Therefore, the carrier band body 1, the large convex hull 2 and the small convex hull 3 of the carrier band pup joint are lifted up simultaneously, so that the small convex hull 3 of the carrier band pup joint is effectively prevented from being distorted and deformed when a worker pulls out the carrier band pup joint, and compared with a material taking mode shown in fig. 10, the production quality of the carrier band pup joint is greatly improved. In addition, this apparatus for producing passes through the linkage cooperation of extracting mechanism 19, step motor B16, has realized on automatic collecting the material platform 38 with the carrier band nipple joint, need not manual the getting of getting, further shortened the production time of carrier band nipple joint, further improved the production efficiency of carrier band nipple joint.
