Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0041] According to a first aspect of the present invention, there is provided an automatic traction device applied to a roll packaging system to realize automatic control of the roll conveying, which can automatically adjust the roll position and travel speed according to the process rhythm of a specific workstation, and can control the buffer length of the roll between two consecutive specific workstations, thereby realizing automated operation, reducing labor intensity and improving production efficiency.

[0042] Reference Figure 1 In some embodiments, an automatic traction device applied to a tape and roll packaging system includes a traction module 10 and a braking module 20 .

[0043] The traction module 10 is arranged at the discharge side of the specific station 30 in the tape packaging system, and the brake module 20 is arranged at the feed side of the specific station 30, that is, the traction module 10 corresponds to the downstream of the specific station 30 in the tape packaging system, and the brake module 20 corresponds to the upstream of the specific station 30 in the tape packaging system. The tape in the tape packaging system enters the specific station 30 from the brake module 20, and the production and testing of semiconductor components can be carried out in the specific station 30. After the tape is output from the specific station 30, it enters the traction module 10.

[0044] In the application, the specific station 30 operates at a preset process speed to produce and test the semiconductor components on the tape. In some embodiments, the specific station 30 is used to process the material on the tape of the set process length within the takt time corresponding to each process takt. If the takt time corresponding to each process takt is recorded as t, the set process length is recorded as L, and the preset process speed is recorded as ,but .

[0045] Reference Figure 2 The traction module 10 is used to detect the running state signal b of the tape at the traction module 10, and the braking module 20 is used to detect the running state signal a of the tape at the braking module 20. The running state signal of the tape may include the real-time tension value of the tape at the corresponding position, the length of the tape passing the corresponding position, and / or the number of products on the tape passing the corresponding position.

[0046] The pulling module 10 is also used to adjust the process speed of a specific station 30. The running state signal a of the web at the braking module 20 is used to dynamically adjust the traction force F of the traction module 10 on the web, so that the web is output from the specific workstation 30 at an output speed V.

[0047] The brake module 20 is also used to dynamically adjust the traction force of the brake module 20 on the tape according to the running state signal b of the tape at the traction module 10. , so that the tape is wound at the input speed Enter the specific workstation 30 and make the real-time tension value of the web within the set tension threshold range.

The brake module 20 can provide braking force when the tape is running, so that the tape maintains a certain tension during the process of entering and exiting the specific station 30, avoiding warping of the tape, and ensuring the reliability of the production process and product accuracy.

In addition, the set tension threshold range can be reasonably set according to the actual situation of the material and thickness of the tape. The dynamic adjustment process of the traction force of the traction module 10 on the tape and the traction force of the brake module 20 on the tape can be combined with the PID (Proportional-Integral-Derivative) control algorithm in the prior art.

In other words, the two adjacent groups of automatic traction devices can control the buffer length of the tape between the corresponding two specific stations, provide a buffer space for the tape, thereby matching the process rhythm of different specific stations, realizing automated operation, and eliminating the need to transfer the tape after winding it onto the tape reel, which can reduce labor intensity and improve production efficiency.

The running speed and travel length of the tape 40 are automatically controlled. In addition, a tape buffer space is formed between the traction module 101 and the brake module 202, and the traction module 101 is used to adjust the process speed of the specific station 301. , the running status signal of the belt at the brake module 201 and the running status signal of the belt 40 at the brake module 202 , dynamically adjust the pulling force of the pulling module 101 on the tape 40 , and control the output speed of the tape , so that the tape length at the tape buffer space is not less than the set buffer length. The set buffer length can be reasonably set according to actual needs.

[0054] Specifically, refer to Figure 1 A web running state detector 14 is provided in the traction module 10. The web running state detector 14 is close to the discharge port of the specific workstation 30, where the web passes through the detection area of ​​the web running state detector 14. The web running state detector 14 is used to provide a web running state signal at the traction module 10, thereby feeding back to the braking module 20, so that the braking module 20 can dynamically adjust the traction force of the braking module 20 on the web and the input speed of the web, and control the web tension within the set tension threshold range, so as to ensure that the web is flat and has no warping, and to ensure the web positioning accuracy.

[0055] A web running status detector 24 is provided in the braking module 20.

[0056] It should be noted that the pulling method of the belt 40 can be reasonably set according to actual conditions.

[0057] Reference Fig. 9 In some embodiments, the reel 40 is provided with clamping holes 41 distributed along its length direction. The design of the clamping holes 41 can facilitate the traction and braking operations of the reel 40.

Correspondingly, a counting sensor (not shown in the figure) is provided on the side of the brake gear 25, and the teeth of the brake gear 25 are in the detection area of ​​the counting sensor, and the counting sensor can detect the rotation speed and number of rotations of the brake gear 25, so as to obtain the traveling speed and traveling length of the tape on the second guide platform 21, so as to accurately control the position of the tape.

[0064] It should be noted that the tape structures of different semiconductor components are also different. The clamping holes can be set on both sides of the tape, or only on one side of the tape. The structures of the traction gear 15 and the brake gear 25 can be designed to match the structure of the tape.

Refer to Fig.10 In other embodiments, a clamping hole 41 is provided on one side of the winding belt 40, so that the traction gear and the brake gear can be respectively set as single-row gears.

[0065] In some embodiments, the first guide platform 11 and the second guide platform 21 are respectively provided with an elastic clamping mechanism, which includes a mounting plate and a clamping spring, wherein the mounting plate is disposed above the corresponding guide platform, the clamping spring is disposed at the bottom of the mounting plate, and the lower end of the clamping spring abuts against the roll on the corresponding guide platform. Figures 5 to 7An elastic clamping mechanism 13 is provided on the first guide platform 11. The elastic clamping mechanism 13 includes a mounting plate 131 and a clamping spring 132. The mounting plate 131 is provided above the first guide platform 11. There is a gap between the mounting plate 131 and the first guide platform 11. The clamping spring 132 is provided at the bottom of the mounting plate 131, and the lower end of the clamping spring 132 abuts against the tape on the first guide platform 11, so that the tape fits the first guide platform 11 to prevent the tape from warping and deforming. Furthermore, the clamping spring 132 is inclined from top to bottom toward the conveying direction of the tape, and the projection of the clamping spring 132 on the first guide platform 11 is kept in a straight line with the corresponding first opening 111. In this way, it can ensure that the clamping hole on the tape at the first opening 111 is accurately engaged with the tooth portion of the traction gear 15, thereby improving the reliability of the device. Refer to Figure 8 An elastic pressing mechanism 23 is disposed on the second guide platform 21 , and the structure of the elastic pressing mechanism 23 is similar to that of the elastic pressing mechanism 13 , which will not be described in detail herein.

[0066] Furthermore, the elastic pressing mechanisms 13 and 23 can be respectively configured as detachable structures, so as to facilitate the introduction of the tape into the first guide platform 11 or the second guide platform 21 before the tape packaging system is operated. Figures 5 to 7 Taking the elastic clamping mechanism 13 at the first guide platform 11 as an example, the two sides of the mounting plate 131 are respectively provided with a shaft portion 1311 and a slot 1312, and the two sides of the first guide platform 11 are respectively provided with a hinge portion 112 and a clamping assembly 113. The shaft portion 1311 is hingedly matched with the hinge portion 112, and the clamping assembly 113 includes a positioning seat 1131, a spring 1132 and a hook 1133.

Furthermore, the central axis of the rotating shaft portion 1311 , the central axis of the hinge portion 112 , and the hinge axis of the hook 1133 are all parallel to the length direction of the first guiding platform 11 .

[0067] The hook 1133 in the engaging assembly 113 is configured as a lever structure. When the tape needs to be introduced into the first guide platform 11, the bottom end of the hook 1133 can be pressed, and the spring 1132 is compressed, and the hook 1133 rotates around the hinge between it and the positioning seat 1131, so that the hook portion is separated from the slot 1312. At this time, the mounting plate 131 can be rotated to form a larger angle between the mounting plate 131 and the first guide platform 11, so that the tape is introduced into the first guide platform 11. After the tape is introduced into the first guide platform 11 and is correspondingly engaged with the teeth of the traction gear 15, the mounting plate 131 is rotated in the opposite direction to reset it, and the hook portion of the hook 1133 is inserted into the slot 1312. Under the elastic force of the spring 1132, the hook 1133 can be clamped in the slot 1312 to fix the mounting plate 131.
