Description

Technical Field

[0001] This utility model belongs to the field of terminal disassembly technology, specifically relating to a continuous terminal cutting fixture. Background Technology

[0002] The distribution box of the circuit power distribution system uses a large number of connectors for conduction, a large part of which are terminals. Terminals are generally formed by continuous die stamping. In order to facilitate processing, storage, transportation and use, the terminals are connected to the material strip through the connecting part. Several terminals are arranged side by side on the material strip to form a terminal strip, which can then be rolled into a disc by a circular paper tray for storage.

[0003] During the terminal stamping process, circular positioning holes are typically machined into the material strip. The main function of these positioning holes is to correct the accuracy of the feeding distance. Precise positioning hole design ensures that the terminals and material strip are conveyed equidistantly to each workstation for processing, thereby avoiding accumulated errors during the feeding process.

[0004] Before actual use, terminals typically need to be removed from the strip. Current technology mostly involves manually cutting the terminals from the strip. However, manual cutting is time-consuming and labor-intensive, unsuitable for mass production, and makes it difficult to control cutting precision. Therefore, it is necessary to design a device that can replace manual terminal cutting. Utility Model Content

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0007] A continuous terminal cutting fixture includes a mounting base, a control box and a drive mechanism electrically connected to the control box on the mounting base, an upper guide plate and a lower guide plate on one side of the control box, a first strip groove for receiving terminal strips on the lower guide plate, and a disassembly tool on the mounting base located on one side of the lower guide plate. The disassembly tool includes a vertical part mounted on the mounting base and an inclined part connected to the top end of the vertical part, with a cutting groove formed between the upper end of the inclined part and the vertical part.

[0008] As an improvement, the drive mechanism includes a first motor and a fixed frame. The first motor is electrically connected to the control box. The output shaft of the first motor is connected to a drive gear. One side of the drive gear is rotatably connected to the fixed frame, and the other side of the drive gear is connected to a drive roller. The other end of the drive roller is rotatably connected to the fixed frame. The drive gear meshes with a driven gear. One side of the driven gear is rotatably connected to the fixed frame, and the other side of the driven gear is connected to a driven roller. The other end of the driven roller is rotatably connected to the fixed frame. The driven roller is located above the drive roller, and a gap is left between the driven roller and the drive roller to allow the material strip of the terminal to pass through.

[0009] As an improvement, a first baffle mechanism is provided on the mounting base at one end of the disassembly tool. The first baffle mechanism includes a first fixing block fixed on the mounting base, and a first baffle plate is provided at one end of the first fixing block near the disassembly tool.

[0010] As a further improvement, a second baffle mechanism is provided on the mounting base at a position on one side of the disassembly tool. The second baffle mechanism includes a second fixing block fixed on the mounting base, and a second baffle plate is provided on the second fixing block at one end near the disassembly tool.

[0011] As an improvement, a counter is provided on the upper guide plate near the feeding end, and the counter is electrically connected to the control box.

[0012] As a further improvement, the length of the lower guide plate is greater than the length of the upper guide plate.

The output end of the second motor is connected to the rotating shaft of the material belt tray, and the rotating shaft is provided with material belt fixing holes.

[0016] Due to the adoption of the above technical solution, the beneficial technical effects of this utility model are as follows:

[0017] This utility model provides a continuous terminal cutting fixture. By passing the material strip between the upper and lower guide plates and then guiding it into the drive mechanism, the drive mechanism moves the material strip forward. When the terminal passes the disassembly blade, the disassembly blade removes the terminal from the material strip. The removed terminal falls into the terminal collection box. Through the cooperation of the drive mechanism and the disassembly blade, hundreds to thousands of terminals can be disassembled per minute, while manual disassembly of terminals can only remove dozens per minute. This utility model can replace manual removal of terminals from the material strip, greatly improving the disassembly efficiency.

[0018] The speed of terminal disassembly can be controlled by controlling the rotation speed of the drive mechanism. The counter can count the number of disassembled terminals in real time. The cooperation of the electric push rod and the cylinder can feed the material strip into the drive mechanism through the first material strip groove of the lower guide plate, realizing the automation of the whole process. The second motor drives the rotating shaft to rotate, so that the disassembled material strip can be wound into the material strip reel for recycling, avoiding the disassembled material strip from piling up and occupying space.

Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall be followed. Where the manufacturers of reagents or instruments are not specified, they are all conventional products that can be purchased commercially.

[0030] Example 1

[0031] like Figure 1-3 As shown, a continuous terminal cutting fixture includes a mounting base 1, a control box 2 and a drive mechanism 3 on the mounting base 1. One side of the control box 2 is provided with an upper guide plate 4 and a lower guide plate 5. The lower guide plate 5 is provided with a first material strip groove 51 for the material strip of the terminal to pass through. A disassembly tool 6 is provided on the mounting base 1 at a position on one side of the lower guide plate 5. The disassembly tool 6 includes a vertical part 61 and an inclined part 62 mounted on the mounting base 1. The bottom end of the inclined part 62 is connected to the top end of the vertical part 61. A cutting groove is formed between the upper end of the inclined part 62 and the vertical part 61, and the upper end surface of the inclined part 62 is an arc surface.

[0032] The drive mechanism 3 includes a first motor 31 and a fixed frame 32. The first motor 31 is electrically connected to the control box 2. The output shaft of the first motor 31 is connected to a drive gear 33. One side of the drive gear 33 is rotatably connected to the fixed frame 32. The other side of the drive gear 33 is connected to a drive roller 34. The other end of the drive roller 34 is rotatably connected to the fixed frame 32. The drive gear 33 meshes with a driven gear 35. One side of the driven gear 35 is rotatably connected to the fixed frame 32. The other side of the driven gear 35 is connected to a driven roller 36. The other end of the driven roller 36 is rotatably connected to the fixed frame 32. The driven roller 36 is located above the drive roller 34, and a gap is left between the driven roller 36 and the drive roller 34 to allow the material strip of the terminal to pass through. When the disassembled material strip enters the gap between the driven roller 36 and the driving roller 34, the first motor 31 drives the driving roller 34 and the driven gear 35 to rotate through the driving gear 33. The driven gear 35 drives the driven roller 36 to rotate. The rotation of the driving roller 34 and the driven roller 36 can pull the disassembled material strip forward, thereby continuously pulling the terminal forward, making it easier for the disassembly tool 6 to remove the terminal from the material strip, which greatly improves the disassembly efficiency.

[0033] A first baffle mechanism 7 is provided on the mounting base 1 at one end of the disassembly tool 6. The first baffle mechanism 7 includes a first fixing block 71, which is fixed to the mounting base 1 by bolts. A first baffle plate 72 is provided on the end of the first fixing block 71 near the disassembly tool 6. A second baffle mechanism 8 is provided on the mounting base 1 on one side of the disassembly tool 6. The second baffle mechanism 8 is located in the middle part between the disassembly tool 6 and the first baffle mechanism 7. The second baffle mechanism 8 includes a second fixing block 81, and a second baffle plate 82 is provided on the end of the second fixing block 81 near the disassembly tool 6. As needed, the first fixing block 71 and / or the second fixing block 81 can be moved by loosening the bolts, and then the first fixing block 71 and / or the second fixing block 81 can be fixed to the mounting base 1 by tightening the bolts. The first baffle mechanism 7 and the second baffle mechanism 8 can prevent the terminals from jumping around after disassembly, making the disassembly process safer.

[0034] A counter 9 is installed on the upper guide plate 4 near the feeding end, and the counter 9 is electrically connected to the control box 2. The counter 9 can count the number of disassembled terminals in real time.

[0035] Example 2

[0036] like Figure 1-9 As shown, the structure of the continuous terminal shearing fixture in this embodiment is basically the same as that in Embodiment 1, except that:

[0037] The lower guide plate 5 is longer than the upper guide plate 4. The mounting base 1 also has a fixed base 10, which has a slide rail. A slider 11 is mounted on the slide rail, with one end connected to the output end of the electric push rod 12. A positioning cylinder 13 is mounted on the slider 11, and a positioning rod 14 is connected to the output end of the positioning cylinder 13. The fixed base 10 has a second material strip groove 15, which corresponds to the position of the first material strip groove 51. The positioning rod 14 is located above the second material strip groove 15 and is needle-shaped, with a silicone pad covering its bottom end. The electric push rod 12 and the positioning cylinder 13 can also be controlled by the control box 2 to further improve the automation of the terminal disassembly process.

[0038] The mounting base 1 has a through hole 16 located between the disassembly tool 6 and the fixing base 10, and a terminal collection box is located below the through hole 16. The force applied by the disassembly tool 6 after disassembly allows the terminals to fall into the terminal collection box through the through hole 16, facilitating the collection of the disassembled terminals.

[0039] A material rack 17 is provided on one side of the mounting base 1, and a material tray 18 is rotatably mounted on the material rack 17. Terminal strip is wound inside the material tray 18. A strip holder 19 is provided at the end of the mounting base 1 away from the material tray 18. A second motor 20 is fixedly mounted on the strip holder 19, and a strip tray 21 is rotatably mounted on it. The output end of the second motor 20 is connected to the rotating shaft 22 of the strip tray 21. The rotating shaft 22 has a strip fixing hole 23, which can accommodate the starting end of the strip, making it easy for the strip to be wound neatly. Through the cooperation of the second motor 20 and the strip tray 21, the disassembled strip can be collected and processed.

[0040] The working process of this utility model is as follows: First, the strip with terminals on the tray 18 is fed into the second strip groove 15 of the fixed base 10. The positioning cylinder 13 is activated, and the positioning cylinder 13 drives the positioning rod 14 to move downward, so that the bottom end of the positioning rod 14 contacts the strip. Then, the electric push rod 12 is activated, and the electric push rod 12 pushes the positioning rod 14 forward. The positioning rod 14 drives the strip to move into the first strip groove 51 of the downward guide plate 5. After moving a certain distance, the positioning cylinder 13 drives the positioning rod 14 to move upward, and the electric push rod 12 returns to the starting position. The positioning cylinder 13 is activated again, and the positioning cylinder 13 drives the positioning rod 14 to move downward, so that the bottom end of the positioning rod 14 contacts the strip. After contacting the material strip, the electric push rod 12 is activated, which pushes the positioning rod 14 forward. The positioning rod 14 drives the material strip to move into the first material strip groove 51 of the downward guide plate 5. The above actions are repeated until the material strip enters the gap between the driven roller 36 and the driving roller 34. Then, the positioning cylinder 13 and the electric push rod 12 are stopped. The first motor 31 is activated, which drives the driving roller 34 and the driven roller 36 to rotate simultaneously, thereby pulling the material strip forward continuously. During the forward movement of the material strip, the terminals enter the cutting groove of the disassembly tool 6. The disassembly tool 6 will remove the terminals from the material strip until all the terminals are removed from the material strip. Then, the first motor 31 is turned off.
