Description

Technical Field

[0001] This invention relates to the field of terminal stripping technology, and more particularly to a carrier tape terminal bending and stripping device. Background Technology

[0002] In the manufacturing process of electronic components, carrier tape and terminals are usually integrally formed through continuous stamping or injection molding. This production method enables rapid and mass production of terminals and carrier tape substrates, offering advantages such as high production efficiency, good positioning consistency, and suitability for automated assembly line operations. After integral molding, the terminals are connected to the carrier tape via tiny connecting bridges, facilitating subsequent winding, packaging, and transportation, and providing a stable material supply foundation for automated assembly.

[0003] However, this one-piece molding structure also brings challenges to material removal: although the connecting bridge is thin, it has a certain strength and toughness. If the terminals are separated by traditional direct bending or punching methods, the terminals are easily deformed, scratched or burrs are generated due to stress concentration or uneven distribution, which affects the subsequent welding or assembly quality. At the same time, with the trend of miniaturization of electronic products, the terminal size is getting smaller and the arrangement is getting denser, and the requirements for the accuracy of material removal position and separation quality are becoming increasingly stringent.

[0004] Therefore, how to achieve high-quality, low-damage separation of terminals and carrier tape while maintaining the advantages of integrated molding production efficiency has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To address the aforementioned shortcomings, the present invention aims to provide a carrier terminal bending and stripping device. By indenting the connecting bridge before bending and stripping, the stripping position is accurate and the terminals are undamaged, significantly improving product yield. Furthermore, it enables precise transportation and enhances operational accuracy.

[0006] To achieve the above objectives, the present invention provides a carrier terminal bending and unloading device, including a base, a horizontal worktable mounted in the middle of the base, and an extension plate provided at one end of the worktable;

[0008] The workbench is equipped with a stripping mechanism, which includes a stripping shaft that rotates symmetrically on the workbench. The bottom end of the stripping shaft is provided with an eccentric swing member. A guide rail is horizontally slidable below the eccentric swing member. The eccentric swing member is used to drive the guide rail to reciprocate horizontally along a direction perpendicular to the conveyor belt. The guide rail is provided with stripping pushers. Two stripping pushers alternately push the terminal to reciprocate and bend.

[0011] According to the carrier tape terminal bending and stripping device of the present invention, an upstream telescopic rod is connected to one end of the translation seat near the extension plate. The upstream telescopic rod includes an upstream inner rod and an upstream outer rod that are elastically connected. The upstream outer rod is connected to the translation seat, and the upstream inner rod is connected to the drive seat. A protruding spring is provided at one end of the upstream inner rod away from the translation seat. An ear plate is provided on the top surface of one end of the indentation conveying seat away from the translation seat. A through groove corresponding to the upstream inner rod is provided on the ear plate.

[0013] According to the carrier tape terminal bending and stripping device of the present invention, an eccentric connecting rod is provided at the top of the stripping shaft, and wavy flanges are provided on both sides of the translation seat parallel to the carrier tape conveying direction, with the crests and troughs of the two wavy flanges corresponding to each other.

[0017] This invention provides a carrier tape terminal bending and unloading device, which has the following advantages:

[0018] 1. Before bending and stripping, a crease is pre-pressed at the connection bridge between the terminal and the carrier tape by an indentation mechanism. This ensures stress concentration and precise fracture location during subsequent bending and stripping, effectively preventing terminal deformation or damage and significantly improving product yield.

[0019] 2. The alternating push stripping method is adopted, which makes the terminal bend back and forth until it breaks naturally at the connecting bridge. The stripping is thorough and there is no impact damage to the terminal, which can meet the needs of continuous production.

[0020] 3. By alternating clamping of the upstream and downstream positioning claws, the position of the carrier belt is kept stable throughout the entire process of indentation, conveying, and unloading, avoiding deviation or slippage and improving operational accuracy.

[0021] In summary, this invention, by indenting the connecting bridge before bending and stripping, ensures precise stripping positioning and prevents damage to the terminals, significantly improving product yield and enabling precise delivery, thus enhancing operational accuracy.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] See Figures 1-9 The present invention provides a carrier terminal bending and stripping device, including a base 1, a worktable 27, an indentation mechanism 4 and a stripping mechanism 5. A horizontal worktable 27 is mounted in the middle of the base 1, and an extension plate 271 is fixedly connected to the feeding end of the worktable 27.

[0034] The indentation mechanism 4 includes an indentation conveyor seat 41 slidably disposed on the extension plate 271. An upstream positioning seat 42 is symmetrically slidably connected to the indentation conveyor seat 41. The movement direction of the upstream positioning seat 42 is perpendicular to the transport direction of the carrier tape. An upstream positioning claw 43 is fixedly connected to each of the upstream positioning seats 42. The upstream positioning claw 43 is used to clamp the carrier tape. An indentation seat 44 is slidably connected to the upstream positioning seat 42 along its movement direction. An indentation claw 441 is detachably connected to the indentation seat 44. The indentation claw 441 is used to press out creases on the connecting bridge between the carrier tape and the terminal.

[0035] The unloading mechanism 5 includes an unloading shaft 51 symmetrically rotatably mounted on the worktable 27. An eccentric swing member 56 is fixedly connected to the bottom end of the unloading shaft 51. A guide rail 57 is slidably connected to the worktable 27 below the eccentric swing member 56. The eccentric swing member 56 is used to drive the guide rail 57 to reciprocate horizontally. The direction of movement of the guide rail 57 is perpendicular to the direction of conveyor belt transport. Unloading pushers 59 are connected to the guide rail 57. Two unloading pushers 59 are respectively located on both sides of the terminal. The two unloading pushers 59 alternately push the terminal fixedly connected to the carrier belt, causing the terminal to bend back and forth until the connecting bridge breaks and the terminal is separated from the carrier belt.

[0036] See Figure 1 and Figure 2 A feeding tray 11 is rotatably connected to one end of the top surface of the base 1. The feeding tray 11 is located on the side of the workbench 27 near the extension plate 271. A waste tray 12 is rotatably connected to the other end of the top surface of the base 1. The feeding tray 11 is used to support and install the feeding roller. The feeding roller is wound with unremoved carrier tape (i.e., the carrier tape is connected to the terminal). The waste tray 12 is used to support and install the waste roller. The waste roller is used to wind the empty carrier tape after removal. A motor for driving the waste tray 12 to rotate is fixedly installed on the base 1. The output shaft of the motor is connected to the waste tray 12 through a coupling, so that it can drive the waste tray 12 to rotate.

[0037] See Figures 1-5 A hollow base 2 is fixedly connected to the middle of the base 1, and a support frame 24 is fixedly connected to the top of the base 2. The support frame 24 is positioned between the feed tray 11 and the waste tray 12. The workbench 27 and the extension plate 271 are both fixedly connected to the support frame 24. A top cover 241 is detachably connected to the top of the support frame 24. A cylinder slide 25 is fixedly connected to the top cover 241, and the cylinder slide 25 is located below the top cover 241. A sliding seat 26 is slidably connected to the cylinder slide 25, and the movement direction of the sliding seat 26 is parallel to the conveying direction of the carrier belt. Air pipes 251 are fixedly connected to both ends of the cylinder slide 25. A connecting pipe 23 is sealed to the air pipe 251 and sealed to the drive component 22. The drive component 22 is fixedly installed on the top surface of the base 1. The cylinder slide 25 is a mature existing technology, and its structure and principle are common knowledge to those skilled in the art, so it will not be described in detail here. A connecting frame 261 is fixedly connected to the bottom end of the sliding seat 26. The connecting frame 261 is fixedly connected to the translation seat 6. The translation seat 6 is slidably connected to the top surface of the workbench 27 and the top surface of the extension plate 271. The movement direction of the translation seat 6 is parallel to the conveying direction of the carrier belt.

[0038] See Figure 5 and Figure 6The indentation mechanism 4 includes an indentation conveyor 41 and an upstream positioning seat 42. The indentation conveyor 41 is slidably connected to the extension plate 271 along the conveying direction of the carrier belt. The upstream positioning seat 42 is symmetrically slidably connected to the indentation conveyor 41, and the movement direction of the upstream positioning seat 42 is perpendicular to the conveying direction of the carrier belt. An upstream positioning claw 43 is fixedly connected to the upstream positioning seat 42. The upstream positioning claw 43 is used to clamp and fix the carrier belt before indentation. A return spring is connected between the upstream positioning seat 42 and the indentation conveyor 41. Furthermore, the return springs are all compression springs. When the return spring is in its natural state, the upstream positioning claw 43 does not contact the carrier belt. The top surface of the upstream positioning seat 42 is provided with a guide groove 421, which includes a starting section, a connecting section and a clamping section. The starting section is located at one end of the upstream positioning seat 42 near the worktable 27, the clamping section is located on the side of the starting section away from the extension plate 271, and the connecting section is used to smoothly connect the starting section and the clamping section. The top surface of the indentation conveyor seat 41 is slidably connected to a drive seat 621 along the conveying direction of the carrier belt. The bottom surfaces of both ends of the drive seat 621 are fixedly connected to guide posts 622 that can cooperate with the guide groove 421.

[0039] The guide post 622 enters the clamping section after passing through the connecting section from the starting section. Under the action of the shape of the guide post 622 and the guide groove 421, the two upstream positioning seats 42 approach each other, and the upstream positioning claw 43 clamps the carrier belt located below the indentation conveyor seat 41.

[0040] See Figure 5 and Figure 6 An indentation seat 44 is slidably connected to the upstream positioning seat 42 along its direction of movement. An indentation claw 441 is detachably connected to the bottom end of the indentation seat 44, and an indentation knife is fixedly connected to the indentation claw 441. The indentation knife is used to press out creases at the connecting bridge. A crossbar is fixedly connected to the side wall of the upstream positioning seat 42. The crossbar passes through the indentation seat 44 to realize the sliding connection between the indentation seat 44 and the upstream positioning seat 42. At the same time, at least one auxiliary spring is connected between the adjacent indentation seat 44 and the upstream positioning seat 42. Furthermore, all auxiliary springs are compression springs. Each of the upstream positioning seats 42 has a lever 46 rotatably connected to its top surface. A connecting shaft is fixedly connected to the middle of the lever 46, and the connecting shaft is rotatably connected to the upstream positioning seat 42. One end of the lever 46 extends above the indentation seat 44. A convex shaft 45 is fixedly connected to the top surface of the indentation seat 44. A clearance groove corresponding to the convex shaft 45 is provided on the lever 46. The other end of the lever 46 extends to the end of the clamping section away from the connecting section.

[0041] When the guide post 622 is in the clamping section, the upstream positioning claw 43 clamps the carrier belt. At this time, the translation seat 6 continues to move away from the worktable 27 relative to the indentation conveyor seat 41 until the guide post 622 abuts against the side wall of the lever 46. The guide post 622 can push the lever 46 to rotate a certain angle around the connecting shaft. Under the cooperation of the convex shaft 45 and the clearance groove on the lever 46, the indentation seat 44 is pushed to move closer to the carrier belt, so that the indentation claw 441 presses out a crease at the connecting bridge. When the guide post 622 moves closer to the starting section in the clamping section and disengages from the lever 46, the indentation seat 44 is reset under the action of the auxiliary spring.

[0042] See Figure 5 and Figure 6 An upstream telescopic rod 62 is fixedly connected to one end of the translation seat 6 near the indentation conveyor seat 41. A drive seat 621 is fixedly connected to the upstream telescopic rod 62. A plurality of protruding springs 63 are fixedly connected to one end of the upstream telescopic rod 62 away from the translation seat 6. An ear plate 411 is fixedly connected to one end of the indentation conveyor seat 41 away from the worktable 27. A through groove is provided on the ear plate 411 along the conveying direction of the carrier belt. The through groove corresponds to the upstream inner rod.

[0043] When the raised spring 63 is located at the end of the ear plate 411 near the worktable 27, the translation seat 6 moves towards the extension plate 271. At this time, the raised spring 63 cannot pass through the through slot, so the translation seat 6 drives the indentation conveyor seat 41 to move synchronously. When the indentation conveyor seat 41 moves to the end of its end abutting the end of the extension plate 271, the indentation conveyor seat 41 can no longer move, and the raised spring 63 passes through the through slot. At this time, the guide post 622 is located in the clamping section of the guide slot 421, and then the translation seat 6 continues to move in the original direction, causing the guide post 622 to push the lever 46 to rotate at a certain angle, and the indentation claw 441 completes the indentation operation. The translation seat 6 moves in the opposite direction (i.e., moves towards the worktable 27) until the raised spring 63 abuts against the ear plate 411 away from the side wall of the worktable 27. The raised spring 63 cannot pass through the through slot, causing the translation seat 6 to drive the indentation conveyor seat 41 to move horizontally in sync (at this time, the upstream positioning claw 43 clamps the carrier belt), thereby realizing the transport of the carrier belt.

[0044] See Figure 5 , Figure 7 , Figure 8 and Figure 9The unloading mechanism 5 includes an unloading shaft 51 and an eccentric connecting rod 52. A vertical unloading shaft 51 is symmetrically rotatably mounted on the worktable 27. The top end of the unloading shaft 51 is fixedly connected to the eccentric connecting rod 52, which can cooperate with the translation seat 6. A positioning sleeve 53 is rotatably connected to the unloading shaft 51 located below the worktable 27. The positioning sleeve 53 is rotatably connected to the worktable 27, and relative rotation is possible between the positioning sleeve 53 and the unloading shaft 51. A downstream positioning seat 54 is slidably disposed beside the positioning sleeve 53. The downstream positioning seat 54 is elastically connected to the worktable 27 and is located on the side of the positioning sleeve 53 near the center of the worktable 27. Multiple downstream positioning claws 541 for clamping the carrier belt are fixedly connected to the downstream positioning seat 54. A hinge seat is fixedly connected to the positioning bushing 53, and a push rod 531 is hinged to the hinge seat. A torsion spring is fixedly installed at the connection between the push rod 531 and the hinge seat. A reset rod 532 is also fixedly connected to the positioning bushing 53. There is a certain angle between the reset rod 532 and the push rod 531. A synchronous turntable 55 is fixedly connected to the unloading shaft 51 below the positioning bushing 53. A column 551 is fixedly connected to the synchronous turntable 55. The column 551 can contact the hinge seat and the reset rod 532.

[0045] When the translation seat 6 moves between the two stripping shafts 51, under the action of the shape of the translation seat 6 itself, it can drive the two eccentric connecting rods 52 to rotate synchronously in opposite directions around the stripping shaft 51 at a certain angle. When the stripping shaft 51 rotates, the column 551 abuts against and pushes the hinge seat, so that the positioning sleeve 53 rotates synchronously with the stripping shaft 51, and the push rod 531 drives the downstream positioning seat 54 to move towards the carrier belt until the downstream positioning claw 541 clamps the carrier belt. During the above process, the torsion spring does not deform (or only undergoes slight deformation). If the stripping shaft 51 continues to rotate in the original direction, the torsion spring will deform, the push rod 531 will still abut against the downstream positioning seat 54, and the position of the downstream positioning seat 54 will not change; if the stripping shaft 51 rotates in the opposite direction, and the column 551 does not contact the reset rod 532, the positioning sleeve 53 will not rotate, and the position of the downstream positioning seat 54 will not change; if the stripping shaft 51 rotates in the opposite direction, and the column 551 abuts against and pushes the reset rod 532 to move, the positioning sleeve 53 will rotate in the opposite direction, and the downstream positioning seat 54 will reset.

[0046] See Figure 5 , Figure 7 , Figure 8 and Figure 9An eccentric swing member 56 is fixedly connected to the bottom end of the stripper shaft 51. A guide rail 57 is provided below the eccentric swing member 56, and multiple guide rods 571 are fixedly connected to the guide rail 57. A downward bending plate is fixedly connected to the worktable 27. The guide rods 571 pass through the bending plate, allowing the guide rail 57 to slide back and forth perpendicular to the conveying direction of the carrier belt. A pin is fixedly connected to the bottom surface of the eccentric swing member 56 away from the stripper shaft 51, which passes through the guide rail 57. When the stripper shaft 51 drives the eccentric swing member 56 to rotate, the pin and the guide rail 57 work together to drive the guide rail 57 to reciprocate. A stripper frame 58 is fixedly connected to the end of the guide rail 57 near the carrier belt. A stripper pusher 59 is threaded onto the stripper frame 58. The stripper pusher 59 is used to push the terminal to bend back and forth, thereby separating the terminal from the carrier belt.

[0047] See Figures 5-9 The translation seat 6 has two corrugated flanges 61 fixedly connected to its two side walls parallel to the conveyor belt direction. The crests and troughs of the two corrugated flanges 61 correspond to each other. When the translation seat 6 moves between the two stripping shafts 51 and the downstream positioning claw 541 clamps the conveyor belt, the translation seat 6 continues to move in the original direction. The eccentric connecting rod 52 cooperates with the corrugated flanges 61. A torsion spring connects the stripping shaft 51 to the worktable 27. The elastic force provided by the torsion spring allows the stripping shaft 51 to drive the eccentric connecting rod 52 to reciprocate as the contour of the corrugated flanges 61 changes.

[0048] When one of the eccentric connecting rods 52 engages with the crest of one of the wave flanges 61, the guide rail 57 corresponding to the eccentric connecting rod 52 moves towards the carrier belt, and the stripper pusher 59 corresponding to the guide rail 57 pushes the terminal to bend at a certain angle. At the same time, the other eccentric connecting rod 52 engages with the trough of the other wave flange 61. Under the action of the torsion spring, the guide rail 57 corresponding to the eccentric connecting rod 52 moves away from the carrier belt, and the stripper pusher 59 corresponding to the guide rail 57 moves away from the carrier belt simultaneously to avoid contact with the terminal. The above process is repeated, so that the two eccentric connecting rods 52 rotate continuously in opposite directions, thereby causing the two stripper pushers 59 to alternately push the terminal, realizing the reciprocating bending of the terminal until it breaks at the indentation, and the terminal falls off under its own weight.

[0049] See Figure 5 and Figure 6Preferably, to accommodate the different arrangement distances of terminals of different specifications on the carrier tape, a limiting seat 272 is bolted to the extension plate 271. The limiting seat 272 can limit the movement range of the indentation conveyor 41, thereby changing the single feeding distance. At the same time, to accommodate this change, an upstream telescopic rod 62 is provided, including an upstream outer rod and an upstream inner rod sleeved inside the upstream outer rod. The upstream outer rod is fixedly connected to the side wall of the translation seat 6, and a buffer spring is fixedly connected between the upstream inner rod and the upstream outer rod. The drive seat 621 is fixedly connected to the upstream inner rod. When the indentation conveyor seat 41 abuts against the limiting seat 272 and the translation seat 6 has not yet reached between the two stripping shafts 51, the buffer spring is gradually stretched, and the length of the upstream telescopic rod 62 increases. At this time, the position of the upstream inner rod and the drive seat 621 remains unchanged (the protruding spring 63 is located on the side of the ear plate 411 away from the worktable 27). The guide post 622 is in the clamping section of the guide groove 421, so that the upstream positioning claw 43 maintains the clamping state of the carrier belt unchanged until the translation seat 6 cooperates with the eccentric connecting rod 52, the upstream telescopic rod 62 extends to the limit length, the upstream outer rod drives the upstream inner rod and the drive seat 621 to move, and the protruding spring 63 reaches the side of the ear plate 411 near the worktable 27 through the through groove, so that the guide post 622 enters the starting section. Through the above design, it is ensured that at any time, at least one set of the upstream positioning claw 43 and the downstream positioning claw 541 is in the clamping state of the carrier belt, improving the accuracy of the carrier belt transportation.

[0050] See Figures 7-9 Preferably, the static friction between the positioning sleeve 53 and the worktable 27 is greater than the elastic force provided by the torsion spring between the stripper shaft 51 and the worktable 27. This ensures that the torsion spring can only drive the stripper shaft 51 to rotate relative to the worktable 27. When stripping is completed and the translation seat 6 disengages from the area between the two stripper shafts 51, the torsion spring alone cannot drive the positioning sleeve 53 to rotate and reset. In actual implementation, the positioning sleeve 53 and the worktable 27 can be fitted together using conventional connection methods such as nylon friction sleeves, disc springs, or wave washers. These methods are conventional techniques known to those skilled in the art and will not be described in detail here.

[0051] See Figures 5-9A rotating component 65 is slidably connected to the top surface of the workbench 27 away from the extension plate 271 along the conveying direction of the carrier belt. A downstream telescopic rod 64 is provided between the rotating component 65 and the translation seat 6. After the terminal stripping is completed, the translation seat 6 moves towards the extension plate 271. When the translation seat 6 moves to the guide post 622 entering the clamping section, the downstream telescopic rod 64 extends to its limit length, causing the rotating component 65 to move with the translation seat 6. The rotating component 65 pushes the eccentric connecting rod 52 to rotate a certain angle around the stripping shaft 51. The column 551 abuts against and pushes the reset rod 532 to rotate, thereby realizing the reset of the positioning sleeve 53. The end of the rotating component 65 away from the translation seat 6 is fixedly connected to a plurality of insert rods 66 that pass through the worktable 27. After passing through the worktable 27, the insert rods 66 are fixedly connected to the end plate. A plurality of connecting springs are fixedly connected between the end plate and the worktable 27. Furthermore, the connecting springs are all compression springs. When the connecting springs are in their natural state, the rotating component 65 is located at the end of the worktable 27 away from the extension plate 271.

[0052] See Figures 6-9 Preferably, the ends of the upstream positioning claw 43 and the downstream positioning claw 541 that contact the carrier belt are both fixedly connected with elastic pads, which can avoid damage to the carrier belt and ensure a good clamping effect.

[0053] See Figure 7 Preferably, the bottom surface of the worktable 27 is fixedly connected to a guide seat 3, and the guide seat 3 is provided with a guide groove that cooperates with the carrier belt, which can further improve the accuracy of the device.

[0054] See Figures 7-9 Preferably, a plurality of cooperating springs are connected between the downstream positioning seat 54 and the guide seat 3. The two ends of the cooperating springs are fixedly connected to the downstream positioning seat 54 and the guide seat 3, respectively. Furthermore, the cooperating springs are compression springs. When the cooperating springs are in their natural state, the downstream positioning claw 541 does not contact the carrier belt.

[0055] See Figure 5 and Figure 6 Preferably, when the translation seat 6 moves between the two stripping shafts 51 to perform stripping operation, the buffer spring is in a stretched state, so that the indentation conveyor seat 41 is in close contact with the limit seat 272, thus avoiding the indentation conveyor seat 41 from moving erroneously and causing a decrease in positioning accuracy.

[0056] See Figure 1 Preferably, a receiving box 21 is detachably connected to the base 2. The receiving box 21 is located below the support frame 24 and is used to hold terminals.

[0057] See Figures 5-9Preferably, the indentation claw 441 and the indentation seat 44 are detachably connected, so that the indentation claw 441 can be freely adjusted on the indentation seat 44. At the same time, the stripper pusher 59 is threadedly connected to the stripper frame 58, and the extension length of the stripper pusher 59 can also be adjusted to adapt to the stripping operation of terminals with different thickness specifications.

[0058] See Figure 1 and Figure 2 Preferably, the drive unit 22 is an air pump, which can provide sufficient power.

[0059] In the implementation of this invention: the feeding tray 11 and the waste tray 12 respectively support and install the feeding roller and the waste roller, and the carrier belt on the feeding roller passes through the support frame 24 and the guide seat 3 and then wraps around the waste roller.

[0060] When the drive unit 22 is activated, the sliding seat 26 moves towards the feed tray 11 through the cooperation of the connecting pipe 23 and the cylinder slide 25. The sliding seat 26 drives the translation seat 6 to move synchronously through the connecting frame 261. In the initial stage of the translation seat 6's movement, the raised spring 63 is located on the side of the ear plate 411 near the translation seat 6, and the buffer spring does not deform or undergoes slight deformation. The translation seat 6 drives the indentation conveyor 41 to move synchronously until the indentation conveyor 41 abuts against the end side wall of the extension plate 271. At this time, the indentation conveyor 41 can no longer move, and the translation seat 6 moves in the original direction. The raised spring 63 deforms and reaches the side of the ear plate 411 away from the translation seat 6 through the through groove. The translation seat 6 continues to move in the original direction. During the movement of the translation seat 6, the guide post 622 enters the clamping section after passing through the connecting section from the starting section, thereby causing the upstream positioning seat 42 to move towards the carrier belt. The upstream positioning claw 43 stably clamps the carrier belt. The translation seat 6 continues to move in the original direction. The guide post 622 abuts against and pushes the lever 46 to rotate at a certain angle. Under the cooperation of the clearance groove on the lever 46 and the convex shaft 45, the indentation seats 44 approach each other, and the indentation claw 441 presses out a crease on the connecting bridge.

[0061] When the translation seat 6 moves in the opposite direction, the protruding spring 63 is located on the side of the ear plate 411 away from the translation seat 6. Therefore, the translation seat 6 drives the indentation conveyor seat 41 to move. During this period, there is no relative movement between the upstream inner rod and the ear plate 411, or between the drive seat 621 and the indentation conveyor seat 41. Therefore, the guide post 622 is located in the clamping section of the guide groove 421, and the upstream positioning claw 43 maintains the clamping state of the carrier belt, so that the indentation conveyor seat 41 transports the carrier belt.

[0062] When the indentation conveyor 41 abuts against the limiting seat 272, the indentation conveyor 41 cannot continue to move. At this time, the raised spring 63 still cannot pass through the ear plate 411, and the buffer spring is stretched until the translation seat 6 moves between the two stripping shafts 51. The upstream telescopic rod 62 extends to its limit length, and the raised spring 63 passes through the ear plate 411, causing the guide post 622 to return to the starting section. The upstream positioning claw 43 disengages from the carrier belt.

[0063] When the translation seat 6 reaches between the two stripping shafts 51, it pushes the eccentric connecting rod 52 to rotate around the stripping shaft 51 by a certain angle. When the stripping shaft 51 rotates, the column 551 contacts the hinge seat and pushes the positioning sleeve 53 to rotate by a certain angle through the hinge seat. This causes the push rod 531 to push the downstream positioning seat 54 closer to each other. The downstream positioning claw 541 clamps and positions the carrier belt. Then the translation seat 6 continues to move. The wave flange 61 on its two side walls contacts the eccentric connecting rod 52, causing the two stripping shafts 51 to rotate continuously. At the same time, the two stripping shafts 51 rotate in opposite directions. The two stripping pushers 59 alternately push the terminal to bend until it breaks at the indentation. The terminal falls into the receiving box 21.

[0064] The translation seat 6 moves toward the extension plate 271. When the translation seat 6 moves to the guide post 622 entering the clamping section, the downstream telescopic rod 64 extends to its limit length, causing the rotating part 65 to follow the translation seat 6. The rotating part 65 contacts and pushes the eccentric connecting rod 52 to drive the stripping shaft 51 to rotate at a certain angle. The column 551 abuts against and pushes the reset rod 532 to rotate, thereby resetting the positioning sleeve 53. The downstream positioning claw 541 disengages from the carrier belt (at this time, the upstream positioning claw 43 clamps the carrier belt).

[0065] This invention provides a carrier tape terminal bending and unloading device, which has the following advantages:

[0066] 1. Before bending and stripping, a crease is pre-pressed at the connection bridge between the terminal and the carrier tape by an indentation mechanism. This ensures stress concentration and precise fracture location during subsequent bending and stripping, effectively preventing terminal deformation or damage and significantly improving product yield.

[0067] 2. The alternating push stripping method is adopted, which makes the terminal bend back and forth until it breaks naturally at the connecting bridge. The stripping is thorough and there is no impact damage to the terminal, which can meet the needs of continuous production.

[0068] 3. By alternating clamping of the upstream and downstream positioning claws, the position of the carrier belt is kept stable throughout the entire process of indentation, conveying, and unloading, avoiding deviation or slippage and improving operational accuracy.

[0069] In summary, this invention, by indenting the connecting bridge before bending and stripping, ensures precise stripping positioning and prevents damage to the terminals, significantly improving product yield and enabling precise delivery, thus enhancing operational accuracy.
