Description

Technical Field

[0001] This invention relates to the field of capacitor manufacturing technology, specifically to an automatic disassembly and replacement device for checking and replacing material strips and welding cap strips. Background Technology

[0002] Carrier tape is a strip-shaped product used in the field of electronic packaging. It has a specific thickness and has holes (also called pockets) for holding electronic components and positioning holes for indexing and positioning evenly distributed along its length. In the final process of chip capacitor production, it needs to be visually inspected, and then the material is removed, replaced, and the cover tape is welded.

[0003] Publication number "CN115781110A" discloses an automatic welding machine for carrier tape welding, relating to the field of carrier tape welding technology. It includes a fixed base, a welding torch, and a drive mechanism. The drive mechanism includes a control component, a sensing component, and an actuation component. The actuation component moves the welding torch; the sensing component acquires the position information of the actuation component; the control component acquires a start signal and a sensing signal, activates the actuation component based on the start signal, and controls the welding torch to perform welding based on the sensing signal. This invention drives the welding torch to move up and down along a stroke using a motor, acquires the welding torch position using an inductive switch, and begins welding when the welding torch reaches the welding position. The pressure of the welding torch is controlled by spring compression, improving welding speed and quality. This solves the problems of weak welds and unsightly damaged carrier tape often encountered in traditional manual welding, ensuring both operational accuracy and smooth operation.

[0004] However, the above-mentioned devices and existing technologies still have the following problems during implementation:

[0005] 1. In existing technologies, the cover tape is often welded onto the carrier tape manually. Therefore, the difference in individual techniques may lead to uncertainty in the welding force. After the operation is completed, it is impossible to determine whether the actual peel strength value is within the requirements. There may be problems such as the cover tape not being able to be torn or being unable to be torn off.

[0006] 2. During the mounting of electronic components, the cover tape is peeled off. The automatic mounting equipment uses the precise positioning of the carrier tape index hole to take out the components in the bag one by one and mount them on the integrated circuit board (PCB). The peel strength between the carrier tape and the cover film is very important in use and production. Currently, peel strength testing often relies on an independent peel tester. This equipment clamps the cover tape and carrier tape between two clamps, and the two clamps move relative to each other. The test needs to be performed after the product is manufactured. If there are peel difficulties, the entire roll of product needs to be readjusted, which causes great losses to production. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic material removal and replacement device for inspection tape and a cover tape welding device, which ensures that the gap between the cover tape and the carrier tape is always consistent, thereby ensuring that the peel strength value after welding is within the requirements, so as to solve the problems mentioned in the background art.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The present invention has a cover strip fixing frame and a suction chamber arranged sequentially above and below the carrier strip adsorption platform. The suction chamber is used to adsorb and limit the carrier strip, and the cover strip fixing frame is used to pull and move the cover strip. During the laying of the cover strip, two sets of welding gun clamps are used to weld the cover strip. This solves the problem of individual differences in manual welding, which makes it impossible to determine the welding fit. It ensures that the gap between the cover strip and the carrier strip is always consistent, thereby ensuring that the peel strength value after welding is within the requirements.

[0022] 2. In this invention, since the cover tape fixing frame reciprocates on the carrier tape adsorption table, after welding, the cover tape fixing frame moves back a set distance, and one end of the cover tape is fixed by the cover tape clamp on the fixing shaft. A tension sensor is set in the cover tape clamp, and peeling is performed directly on the welding table to directly detect the peeling strength. There is no need to remove the product and test directly on the welding table, which reduces manual operation and transfer process, improves production efficiency, and facilitates the re-welding of unqualified products.

[0023] 3. In this invention, a fixed shaft and a tensioning shaft are respectively provided in the cover belt fixing frame. The fixed shaft and the tensioning shaft are elastically installed in the cover belt fixing frame, and the elastic connecting devices are arranged oppositely in the vertical direction to tension the cover belt. With the help of the floating roller, the cover belt is kept flat at all times, and the distance between the cover belt and the carrier belt remains unchanged.

[0024] 4. In this invention, during the movement of the cover tape fixing frame, the welding gun clamping frame moves synchronously. A synchronous strip with elastic connection is provided at the top of the clamping frame fixing rod of the welding gun clamping frame. In conjunction with the guide rail provided in the carrier tape adsorption table, during the movement, the connecting rod reciprocates along the concave and convex surfaces in the guide rail, so that the welding gun matches the curved movement of the guide rail, ensuring that while ensuring the peel strength, the welding area is increased as much as possible, and preventing the cover tape and the carrier tape from separating.

[0025] 5. In this invention, a set of take-up rollers is set in the suction chamber, and a set of traction rods that move synchronously with the moving pressure rod are used to pull the shielding film cloth to move in the suction chamber to shield the suction holes and adjust the adsorption air volume of the welded cover strip section so as to minimize the adsorption air volume and avoid excessive adsorption force on the welded carrier strip, which would affect the welding strength.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1-11 This invention provides a technical solution: an automatic material removal and replacement device for inventory strips and a cover strip welding device.

[0040] Example 1:

[0041] Please see Figure 1 and Figure 2The device includes a carrier tape adsorption platform 1. First electric sliding platforms 2 are symmetrically arranged on both sides of the upper surface of the carrier tape adsorption platform 1. A platform 14 is connected to the first electric sliding platforms 2 via a column 5. Several sets of suction holes 3 are equidistantly arranged at the center of the carrier tape adsorption platform 1. A suction chamber 6 for adsorbing the carrier tape is fitted to the bottom of the carrier tape adsorption platform 1. The suction chamber 6 is divided into a first chamber 601, a second chamber 602, and a third chamber 603 by a partition 47. Each of the first chamber 601, second chamber 602, and third chamber 603 is connected to a suction pipe 4. 6 is fixedly connected to an external suction device, and the first chamber 601, the second chamber 602 and the third chamber 603 are all connected to the suction hole 3. In this embodiment, the suction chamber 6 is used to place the carrier tape to be welded. The suction hole 3 opened in the carrier tape adsorption table 1 and the suction chamber 6 are used in conjunction to start the external fan. The suction pipe 46 is used to perform suction operation on the first chamber 601, the second chamber 602 and the third chamber 603 respectively to adsorb the carrier tape, ensure that the carrier tape is laid flat and spread out, and facilitate the control of the welding distance between the carrier tape and the cover tape.

[0042] Please see Figure 3 A traction assembly for fixing the cover strap 19 and moving the cover strap 19 is slidably installed on the carrier belt adsorption platform 1. The traction assembly includes a platform 14 and a cover strap fixing frame 20 vertically slidably installed at the bottom of the platform 14. A fixing screw sleeve 12 is fixedly installed inside the platform 14, which increases the contact area of ​​the adjusting screw 13 inside the platform 14. The adjusting screw 13 is threadedly connected to the fixing screw sleeve 12. The top of the cover strap fixing frame 20 is rotatably connected to the adjusting screw 13. Guide posts 58 are symmetrically arranged on the top of the cover strap fixing frame 20, and the guide posts 58 are slidably connected to the platform 14. In this embodiment, the cover strap fixing frame 20 is connected by the fixing screw sleeve 12 and the adjusting screw 13, which facilitates the vertical position adjustment of the cover strap fixing frame 20. The tension of the cover strap 19 can be adjusted according to specific implementation requirements. In specific implementation, rotating the adjusting screw 13 allows it to slide vertically inside the fixing screw sleeve 12, thereby causing the cover strap fixing frame 20 to move.

[0043] Please see Figure 4 and Figure 6The cover strap fixing frame 20 has symmetrical notches 23 on both sides. A fixing shaft 21 and a tensioning shaft 22 are slidably arranged in the notches 23. Each of the fixing shaft 21 and tensioning shaft 22 is provided with an elastic connection component between itself and the cover strap fixing frame 20. The elastic connection component includes a spindle 30 disposed inside the fixing shaft 21 and tensioning shaft 22. Sliding blocks 29 are rotatably sleeved at both ends of the spindle 30. Two sets of notch baffles 25 are symmetrically arranged on both sides of the notch 23. A support plate 28 is fixedly connected to one side of the notch baffle 25. A guide rod 34 is slidably installed in the support plate 28. A limit plate 33 is provided at one end of the guide rod 34. The limit plate 33 and the support plate 28 are connected to each other. A first compression spring 32 is provided between the support plates 28. In this embodiment, a fixed shaft 21 and a tensioning shaft 22 are elastically connected in the cover belt fixing frame 20. At the same time, a cover belt fixing roller 45 is provided on one side of the carrier belt adsorption table 1 through two sets of ear plates 10. The cover belt 19 is wound on the surface of the cover belt fixing roller 45. Therefore, in specific operation, one end of the cover belt 19 is fixedly installed on the surface of the fixed shaft 21 to ensure that the cover belt 19 is in contact with the surfaces of the fixed shaft 21 and the tensioning shaft 22 respectively, so as to ensure that the cover belt 19 generates a tensile force on the elastic connection components of the fixed shaft 21 and the tensioning shaft 22, and ensure that the cover belt 19 is tightened, thereby improving the welding effect compared with manual welding.

[0044] Please see Figure 5 A support frame 26 is symmetrically arranged on the outer wall of the cover belt fixing frame 20 near the tensioning shaft 22. A floating roller 27 is rotatably installed inside the support frame 26. A movable pressure rod 18 is slidably arranged inside the carrier belt adsorption table 1 via the first electric slide table 2. The movable pressure rod 18 is fixedly connected to the slider of the first electric slide table 2 via the connecting frame 17. The movable pressure rod 18 is set to press the cover belt 19 with traction. During the process of the cover belt fixing frame 20 driving the cover belt 19 to move, the movable pressure rod 18 is always pressed against the upper surface of the cover belt 19, and the positions of the movable pressure rod 18 and the floating roller 27 correspond. In this embodiment, the rotatable floating roller 27 arranged outside the cover belt fixing frame 20 is used to support the cover belt 19 and generate a relative tension with the movable pressure rod 18, which further flattens the cover belt 19.

[0045] Please see Figure 7 A mounting groove 2001 is symmetrically provided on one side of the surface of the fixed shaft 21. A cover strip clamp 24 is provided in the mounting groove 2001. A clamping plate 37 is elastically connected to the cover strip clamp 24 through a second compression spring 35. An adjusting rod 36 is provided through the second compression spring 35. The adjusting rod 36 is slidably connected to one side of the cover strip clamp 24. A tensile sensor for monitoring the peel strength value is provided in the cover strip clamp 24. In this embodiment, the cover strip 19 is positioned by using two sets of cover strip clamps 24. The cover strip 19 is inserted into the cover strip clamp 24. The adjusting rod 36 and the second compression spring 35 apply force to the clamping plate 37 to clamp the cover strip 19. At the same time, the second compression spring 35 of the adjusting rod 36 is selected to facilitate the removal of the cover strip 19 after welding.

[0046] Please see Figure 8 and Figure 9 A welding torch holder 4 is symmetrically arranged on both sides of the carrier tape and slidably installed inside the platform 14. The welding torch is fixed by the welding torch holder 4. The welding torch holder 4 is distributed at the welding position on both sides of the carrier tape. A holder fixing rod 15 is symmetrically and slidably installed inside the platform 14. The welding torch holder 4 is slidably installed on the surface of the holder fixing rod 15. The two sets of holder fixing rods 15 are connected by a synchronization bar 11. A positioning plate 42 is provided on both sides of the synchronization bar 11 on the upper surface of the platform 14. A sliding rod 44 is fixedly connected to both ends of the synchronization bar 11. A third compression spring 43 is provided on the surface of the sliding rod 44 between the synchronization bar 11 and the positioning plate 42. In this embodiment, the holder fixing rod 15 slides in the platform 14 through the sliding groove 1401, which facilitates the adjustment of the position of the welding torch holder 4, thereby adjusting the position of the welding torch. Since the welding area of ​​the welding torch is limited during the welding process, a synchronization bar 11 is provided to drive the welding torch linkage. A connecting rod 39 is fixedly connected to the side, and a connector 40 is fixedly installed at one end of the connecting rod 39. A rolling wheel 41 is rotatably installed inside the connector 40. A guide rail 38 is provided on one side inside the carrier adsorption table 1. The guide rail 38 includes a concave surface 3801 and a convex surface 3802, which are arranged alternately. The rolling wheel 41 is fitted with the concave surface 3801 and the convex surface 3802. In this embodiment, since the rolling wheel 41 is connected to one side of the welding gun holder 4 through the connecting rod 39 and the connector 40, the rolling wheel 41 and the concave surface 3801 and the convex surface 3802 are always fitted by the third compression spring 43. Therefore, when the welding gun holder 4 moves with the cover belt fixing frame 20, the convex surface 3802 will compress the third compression spring 43, thereby changing the trajectory of the welding gun in the welding gun holder 4. Thus, during welding, the welding area of ​​the welding gun is increased, ensuring the welding effect while ensuring the composite peel strength.

[0047] Example 2:

[0048] Please see Figure 10Based on Embodiment 1, during the adsorption process of the carrier tape, adsorption of the carrier tape before welding ensures that the carrier tape always adheres to the upper surface of the carrier tape adsorption table 1 and is subjected to adsorption force, maintaining a flat state. However, after welding, the continuous adsorption may exert excessive force on the welded cover tape carrier tape, affecting the original welding effect. Therefore, in this embodiment, a movable shielding membrane 7 is provided in the suction chamber 6 to shield the suction chamber 6 during the welding process, reducing the adsorption air volume and thus reducing the impact on the welding effect. Specifically, a take-up roller 59 is rotatably installed in the suction chamber 6 near the cover tape fixing roller 45. The take-up roller 59 is provided with torsion springs at both ends. A shielding film 7 is provided on the surface of the winding roller 59. The shielding film 7 is wound onto the surface of the winding roller 59. One side of the shielding film 7 is fixed to the winding roller 59, and the other side is fixedly connected to a traction rod 9. The traction rod 9 is fixedly connected to the moving pressure rod 18 through a connecting rod 8. After welding, it is necessary to reduce the adsorption air volume in a timely manner. Therefore, the traction rod 9 that pulls the shielding film 7 to move is fixedly connected to the moving pressure rod 18 through the connecting rod 8. During the welding and movement, the shielding film 7 unfolds accordingly, shielding the space that does not need adsorption and reducing the air volume. Since the position of the carrier belt needs to be limited at all times during the welding process, the edges of the shielding film 7 and the suction chamber 6 do not need to be completely sealed to ensure that a certain amount of adsorption air volume is left.

[0049] Please see Figure 11Since the suction chamber 6 is controlled by a set of external suction fans, when the shielding membrane 7 shields part of the carrier tape adsorption platform 1, the volume of the suction force decreases, resulting in an increase in the air pressure in the unshielded chamber. Therefore, an air volume adjustment port 49 is provided on one side of the second chamber 602 to ensure that the air pressure in the unshielded chamber remains unchanged while shielding the carrier tape adsorption platform 1, thereby ensuring that the adsorption force of the suction chamber 6 on the carrier tape remains unchanged and will not affect the welding effect. A wind pressure control plate 50 is slidably installed inside the air volume regulating port 49. The wind pressure control plate 50 is a flexible plate. A first push plate 51 is provided on one side of the wind pressure control plate 50. Air volume regulating ports 49 are opened on both sides of the third chamber 603. Wind pressure control plates 50 are also provided inside the air volume regulating ports 49. A second push plate 31 is provided between the two sets of wind pressure control plates 50. A traction ball head 54 is elastically connected to the bottom of one end of the shielding membrane cloth 7. The installation position of the traction ball head 54 matches the first push plate 51 and the second push plate 31. In this embodiment, an installation plate 55 is provided at the bottom of the connecting rod 8. A connecting rod 56 is slidably installed inside the installation plate 55. The traction ball head 54 is fixedly installed at one end of the connecting rod 56. At the same time, the traction ball head 54 and the installation plate 55 are fixedly connected. A fourth compression spring 57 is fixedly connected. The above configuration ensures that when the traction ball head 54 moves to the first push plate 51 and the second push plate 31, it generates a certain thrust, which drives the wind pressure control plate 50 to press down, thereby opening the air volume adjustment port 49. A push rod 53 is provided on one side of the partition 47 between the second chamber 602 and the third chamber 603. One end of the push rod 53 is matched with the traction ball head 54. An electromagnet 52 is provided on one side of the partition 47. At the same time, when the shielding membrane 7 continues to move forward, the push rod 53 can squeeze the traction ball head 54. At this time, the fourth compression spring 57 is compressed, and the traction ball head 54 retracts in the horizontal direction and passes smoothly through the clearance groove 48. At this time, the push plate 51 is attracted by the electromagnet 52, ensuring that the air volume adjustment port 49 is opened.

[0050] Working principle: First, the carrier tape to be welded is placed in the center of the upper surface of the carrier tape adsorption table 1. Its bottom surface is connected to the air suction chamber 6 through the air suction hole 3. Then, the cover tape to be welded is rotated and set on the surface of the cover tape fixing roller 45. Then, one end of the cover tape is sequentially passed through the moving pressure rod 18, the floating roller 27, the tensioning shaft 22 and the fixing shaft 21, and finally fixed in the cover tape clamp 24.

[0051] The external suction fan is started, and the suction chamber 6 is used to adsorb the carrier belt. The welding gun is started, the first electric slide 2 is started, and the moving pressure rod 18 and the cover belt fixing frame 20 are moved synchronously, pulling the cover belt to be laid on the carrier belt, so that the welding surfaces of the two are in contact. Since the welding gun clamp 4 is set in front of the cover belt 19, the welding gun acts on both sides of the upper surface of the carrier belt when the cover belt 19 and the carrier belt are moved to weld. At the same time as the welding gun acts, the cover belt 19 is laid on the carrier belt to complete the welding operation.

[0052] Next, the first electric slide 2 is controlled to move the cover strip fixing frame 20 back a certain distance, which can be set arbitrarily to peel off the welded cover strip and carrier strip. Similarly, the fixed shaft 21 equipped with the cover strip clamp 24 is used to drive the cover strip 19. Since the cover strip clamp 24 is equipped with a tension sensor, the force value change and displacement change during the peeling process are collected by the tension sensor and the displacement sensor built into the equipment, thereby calculating the peeling force, peeling strength, tensile strength, tear strength, deformation rate and other performance indicators of the sample.

[0053] Peel force is a crucial technical indicator for cover tapes. Mounting manufacturers need to peel the cover tape from the carrier tape, remove the electronic components packaged in pockets, and mount them onto circuit boards. During this process, to ensure accurate positioning by the robotic arm and prevent the electronic components from jumping or flipping, the peel force from the cover tape to the carrier tape must be sufficiently stable. Therefore, this invention utilizes a set of bonding devices to directly test the peel force within the device itself, minimizing the manpower and time consumption associated with manual testing or transferring the testing to specialized equipment.
