Description

Technical Field

[0001] The invention relates to the technical field of producing carrier tape pup sections by using flat tapes, and in particular to a production device and method for efficiently and continuously producing carrier tape pup sections. Background Art

[0002] The structure of a carrier short section is as follows Figure 1~Figure 3 As shown, the carrier short section is used to carry electronic products with pins, and the carrier short section includes a carrier body 1, and a plurality of large convex bulges 2 are formed on the bottom surface of the carrier body 1 at intervals along its length direction, and the large convex bulges 2 are integrally formed with the carrier body 1, and a small convex bulge 3 is formed at the bottom of each large convex bulge 2, and the small convex bulge 3 is integrally formed with the large convex bulge 2, and the inner cavity of the small convex bulge 3 is connected with the inner cavity of the large convex bulge 2. Among them, the large convex bulge 2 is used to accommodate the body of the electronic product, and the small convex bulge 3 is used to accommodate the pins of the electronic product to protect the pins.

[0003] In the workshop, the specific production method of producing the carrier tape short section is:

[0004] S1, the worker takes out a Figure 4 The flat belt 4 shown is placed flat on the top surface of the heating plate, and the flat belt 4 is heated by the heating plate to soften the flat belt 4;

[0005] S2, the worker places the flat belt 4 flat on the top surface of the concave template A5 of the first mold, ensuring that the flat belt 4 covers each molding groove 6 in the concave template A5, such as Figure 5 Then, by controlling the downward movement of the punch of the first mold, the punch drives the multiple forming blocks 7 thereon to move downward synchronously, so that each forming block 7 is matched with each forming groove 6, such as Figure 6 As shown, a large convex bulge 2 is formed on the flat belt 4. The structure of the flat belt 4 with the large convex bulge 2 is as shown in FIG. Figure 7 As shown;

[0006] S3, the worker takes away the flat belt 4 with the large convex bumps 2, and then places the flat belt 4 on the top surface of the concave template B8 of the second mold, ensuring that each large convex bump 2 on the flat belt 4 covers each blind groove 9 in the concave template B8, as shown in FIG. Figure 8 Then the second die is controlled to move downward, and the punch drives the plurality of pressure rods 10 thereon to move downward, and the pressure rods 10 squeeze the bottom material of the large convex bulge 2 downward, and when each pressure rod 10 is matched with each blind groove 9, as shown in FIG. Fig. 9 As shown, a small convex bump 3 is formed at the bottom of the large convex bump 2, thereby producing the required carrier tape short section;

[0007] S4. Removal of the carrier short section: The worker pulls the carrier short section upward to remove the carrier short section from the concave template B8. The removal direction is as follows: Fig.10As shown by the middle arrow, the first carrier tape short section is obtained;

[0008] S5. The worker repeats steps S1 to S4 for multiple times to continuously produce multiple carrier tape short sections.

[0009] However, although the method used in the workshop can produce the required carrier tape short section, in actual production, there are still the following technical defects:

[0010] I. In steps S1 to S3, the flat belt 4 needs to be heated by a heating plate first. After the flat belt 4 is heated, the worker rotates the flat belt 4 onto the concave plate A5 of the first mold to form a large convex bump 2 on the flat belt 4; then the flat belt 4 with the large convex bump 2 is rotated onto the concave plate B8 of the second mold to form a small convex bump 3 at the bottom of the large convex bump 2, thereby producing the required carrier short section; and the entire production process requires multiple rotations of the flat belt 4, which undoubtedly increases the production time of the carrier short section, thereby reducing the production efficiency of the carrier short section.

[0011] II. In step S4, when the worker pulls the carrier short section out of the concave template B8, the small convex bulge 3 of the carrier short section is still embedded in the blind groove 9 of the concave template B8, causing the small convex bulge 3 to be twisted and deformed [while the process requires that the small convex bulge 3 has no deformation], thereby reducing the production quality of the carrier short section. In addition, the carrier short section needs to be manually pulled out, which undoubtedly further increases the production time of the carrier short section and further reduces the production efficiency of the carrier short section.

[0012] Therefore, there is an urgent need for a production device and method that can greatly improve the production efficiency and production quality of carrier tape pup sections. Summary of the invention

[0092] A method for efficiently and continuously producing carrier tape short sections comprises the following steps:

[0093] S1, the worker takes out a Figure 4 The flat belt 4 shown is placed flat on the top surface of the strip carrier 15 on the left side of the turnover mechanism 12, ensuring that the flat belt 4 covers each of the molding grooves 6 in the strip carrier 15, as shown in FIG. Fig.26 As shown;

[0094] S2, the stepper motor A13 of the control turnover mechanism 12 is started, the stepper motor A13 drives the rotating plate 14 to rotate, the rotating plate 14 drives the strip carrier 15 thereon to rotate, and the strip carrier 15 drives the flat belt 4 covered thereon to rotate synchronously. When the flat belt 4 rotates 180°, the controller controls the stepper motor A13 to turn off, and at this time the flat belt 4 enters the forming station of the heating and forming mechanism 20, as shown in FIG. Fig. 27 As shown;

[0095] S3, processing the flat belt 4 into a carrier belt short section, the specific operation steps are:

[0096] S31, the piston rod of the first cylinder 22 of the control heating and forming mechanism 20 extends downward, the piston rod drives the heat insulation plate 24 to move downward, the heat insulation plate 24 drives the electric heating plate 25 to move downward, and the electric heating plate 25 moves toward the flat belt 4. When the piston rod of the first cylinder 22 is fully extended, the bottom surface of the electric heating plate 25 just contacts the top surface of the flat belt 4, as shown in FIG. Figure 28-29As shown, at this time, each through groove 26 in the electric heating plate 25 is vertically opposed to the forming groove 6 in the strip-shaped carrier 15;

[0097] S32, turning on the power supply, the power supply energizes the electric heating plate 25, when the electric heating plate 25 is energized, the electric heating plate 25 generates heat, the heat heats the flat belt 4, so that the flat belt 4 is softened;

[0098] S33, the piston rod of the second cylinder 23 of the control heating and forming mechanism 20 extends downward, the piston rod drives the lifting plate 27 to move downward, the lifting plate 27 drives each U-shaped member 28 to move downward synchronously, the U-shaped member 28 drives the pressing cylinder 29, the forming block 7 and the pressing rod 10 to move downward synchronously, the forming block 7 and the pressing rod 10 both pass through the through slot 26 downward and press the flat belt 4 downward, when the forming block 7 cooperates with the forming slot 6, as shown in FIG. Figure 30~Figure 31 As shown, a plurality of large convex hulls 2 are formed on the flat belt 4;

[0099] S34, the piston rods of the pressing cylinders 29 of the heating and forming mechanism 20 are controlled to extend downward, and the pressing cylinders 29 drive the pressing rods 10 to move downward relative to the stationary forming block 7, and the pressing rods 10 press the bottom of the large convex bump 2 downward, so that the bottom material of the large convex bump 2 enters the blind groove 9. When the pressing rods 10 cooperate with the blind groove 9, as shown in 32, a small convex bump 3 is formed at the bottom of each large convex bump 2, thereby producing a carrier tape short section;

[0100] Among them, it can be seen from steps S2~S3 that the worker only needs to first rotate the flat belt 4 to the forming station of the heating and forming mechanism 20, and then control the piston rod of the first cylinder 22 to extend downward so that the electric heating plate 25 contacts the flat belt 4, and then heats the flat belt 4; then, control the piston rod of the second cylinder 23 to extend downward so that the forming block 7 cooperates with the forming groove 6 in the strip carrier 15, and then forms a plurality of large bulges 2 on the flat belt 4; finally, control the piston rod of the pressing cylinder 29 to extend downward so that the pressing rod 10 cooperates with the blind groove 9 in the strip carrier 15, and then forms a small bulge 3 at the bottom of the large bulge 2, and then produces a short section of the carrier.

[0101] It can be seen that this production device is compared with Figure 5~Figure 10 The production method shown can heat the flat belt 4, shape the large convex bump 2 and shape the small convex bump 3 at one time without turning over the flat belt 4 multiple times, thereby shortening the production time of the carrier belt short section and greatly improving the production efficiency of the carrier belt short section.

In addition, the production device realizes automatic collection of the carrier short section on the material receiving table 38 through the linkage cooperation of the material taking mechanism 19 and the stepping motor B16, without manual material taking, further shortening the production time of the carrier short section and further improving the production efficiency of the carrier short section.
