Description

Technical Field

[0001] This utility model relates to the field of terminal block processing equipment, specifically a terminal block stamping and trimming processing equipment. Background Technology

[0002] Terminal blocks can carry multiple terminals for connecting external cables. Terminal blocks are generally made by embedding terminals in an insulating shell through injection molding, clamping, or bolt fixing. However, due to the small size of the terminals, in order to improve installation efficiency, these terminals are generally not cut off from the substrate during installation. Instead, the substrate is used as a component for batch positioning of terminals to improve the efficiency of terminal installation or injection molding. After the insulating shell and terminals are installed, the substrate is cut off from the end of the terminal.

[0003] Patent CN212494786U discloses a stamping and trimming machine for terminal block processing, which can automatically discharge the terminal blocks after cutting, avoiding potential safety accidents caused by manual material handling. However, this equipment still requires workers to position and fix the terminal blocks during processing; otherwise, the processing accuracy cannot be guaranteed. Furthermore, workers still need to put their hands under the punch during the process, posing a risk of injury. Moreover, the debris generated during stamping is difficult to remove, easily affecting processing accuracy.

[0004] Therefore, it is difficult to meet the precision and safety requirements of existing terminal block edge cutting processing. In view of this, this application provides a terminal block punching and edge cutting processing equipment. Utility Model Content

[0010] Optionally, the output end of the stamping push rod is fixed with a connecting plate, and the punch is fixed on the front and rear sides of the connecting plate. The bottom of the connecting plate is connected to a limit cover by a compression spring. The limit cover is used to clamp the top of the terminal block to be processed to compress and limit the terminal block to be processed. The top of the limit cover is fixedly installed with a sliding positioning post that is slidably installed with the connecting plate. The top of the sliding positioning post is integrally formed with an anti-dislodgement limit cover for limiting the stroke of the sliding positioning post.

[0011] Optionally, a limiting device for preventing the processed terminal block from retracting below the punch is fixedly installed on the right side of the frame. The limiting device includes a base fixed to the frame by bolts. A central shaft is integrally formed on the base, and a rotating ring is rotatably mounted on the central shaft. A torsion spring for resetting the rotating ring to its initial position is installed between the rotating ring and the base. A baffle for limiting the leftward movement of the processed terminal block is integrally formed on the rotating ring, and a limiting post for limiting the leftward rotation of the baffle is fixedly installed on the base.

[0012] Optionally, a guide bearing platform for guiding the terminal block to be processed is fixedly installed on the top of the frame, and the top of the guide bearing platform is used to support the substrate so as to facilitate the punch to cut the substrate.

[0013] Optionally, the front and rear sides of the frame are provided with discharge ports at the corresponding punch positions to facilitate the discharge of the cut substrates, and the frame is integrally formed with discharge ramps for guiding the cut substrates to slide into the discharge ports.

Anti-disengagement rings are fixedly installed on the left and right sides of the transverse slide groove to prevent the piston from sliding out of the transverse slide groove and thus limiting the movement distance of the limiting slide rod.

[0017] Compared with the prior art, the beneficial effects of the terminal block punching and trimming processing equipment of this utility model are:

[0018] 1. By using a movable base as a carrier to transport the terminals to be processed, workers are no longer required to work under the punch, thus ensuring their personal safety.

[0019] 2. Through the cooperation of the limiting device and the moving seat, the terminal blocks to be processed can be fixed automatically and the processed terminal blocks can be unloaded. Under the drive of the lead screw motor, the movement is precise, so there is no need for manual positioning and fixing of the terminals to be processed, nor is there a need for manual loading and unloading operations. This not only improves the working accuracy and speed, but also saves manpower.

[0032] To clearly and completely describe the objectives and technical solutions of this utility model, and to more clearly illustrate its advantages, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1: Please refer to Figures 1 to 8This utility model provides a terminal block stamping and trimming processing equipment, including a frame 1 for placing the terminal block 5 to be processed. The terminal block 5 to be processed includes terminal units 502 disposed on the left and right sides of an insulating housing 503, and the terminal units 502 are integrally formed on a substrate 501. A movable seat 10 driven by a lead screw motor 6 moves left and right along the frame 1 to transport the terminal block 5 to be processed. A punch 20 driven by a stamping push rod 13 on the frame 1 cuts off the substrate 501 located on the terminal block 5 to be processed, forming a processed terminal block 21. The terminal block 5 to be processed is fed from the left side of the frame 1, and then transported to the area below the punch 20 by the movable seat 10. After the substrate 501 is stamped and cut off by the punch 20, it becomes the processed terminal block 21. Then the processed terminal block 21 is transported by the movable seat 10 to the right side of the frame 1. Subsequently, the movable seat 10 continues to return to the leftmost side of the frame 1 to transport the terminal block 5 to be processed. The bottom of the insulating housing 503 is provided with a DIN rail groove 505 that mates with an external DIN rail. The movable seat 10 is integrally formed with a mating protrusion 12 that slides with the DIN rail groove 505 and is used to limit the up and down movement of the terminal block 5 to be processed. Through the mating of the mating protrusion 12 and the DIN rail groove 505, the terminal block 5 to be processed can be prevented from shaking and flipping during transportation, thereby ensuring the positional accuracy of the terminal block 5 when it enters below the punch 20. A feeding cylinder 4 for stacking terminal blocks 5 to be processed is provided on the left side of the frame 1. The feeding cylinder 4 includes a cylinder 402 fixedly installed with the frame 1, and the inside of the cylinder 402 has a guide channel 401 with the same cross-section as the terminal blocks 5 to be processed. The bottom of the feeding cylinder 4 has a feed port 403 to facilitate the exit of the terminal blocks 5 to be processed located at the bottom of the guide channel 401. By stacking the terminal blocks 5 to be processed in the guide channel 401, the moving seat 10 can transport all the stacked terminal blocks 5 to be processed in sequence from the feed port 403 to the bottom of the punch 20 for processing. The operator only needs to continue stacking the terminal blocks 5 to be processed in the feeding cylinder 4. Since the operator does not need to position and fix the terminal blocks 5 to be processed under the punch 20, it is safer. Moreover, the shape of the guide channel 401 matches the terminal blocks 5 to be processed, so the operator can simply place them to complete the supply of the terminal blocks 5 to be processed without the need for complicated manual positioning and fixing of the terminal blocks 5 to be processed, thus making the operation simpler.A guide bearing platform 22 is fixedly installed on the top of the frame 1 to guide the terminal block 5 to be processed. The top of the guide bearing platform 22 is used to support the substrate 501 so that the punch 20 can cut the substrate 501. The guide bearing platform 22 restricts the terminal block 5 to be processed from swaying in the front and back direction, so that the position of the terminal block 5 to be processed under the punch 20 is more accurate. On the other hand, it can also be used to support the bottom of the substrate 501, so that the punch 20 can accurately cut the substrate 501 above the guide bearing platform 22, avoiding the bottom of the substrate 501 from deforming during the stamping process due to lack of support, resulting in incomplete cutting.

[0034] Please see Figure 1 , Figure 2 , Figure 8 and Figure 9A connecting device 3 is slidably installed on the movable seat 10. The connecting device 3 includes a lifting rod 306 connected to the movable seat 10 via a return spring 308. A limiting rod 301 is fixed at the top of the lifting rod 306. A mating hole 504 is provided at the bottom of the insulating housing 503 to engage with the limiting rod 301. A trapezoidal mating block 307 is integrally formed on the right side of the lifting rod 306. A limiting slide rod 303 is slidably installed inside the lifting rod 306 via a transverse slide groove 302. A piston 305 is fixedly installed in the middle of the limiting slide rod 303, which slides along the transverse slide groove 302 and provides damping for the limiting slide rod 303 to prevent it from shaking when not under force. Anti-disengagement rings 304 are fixedly installed on the left and right sides of the transverse slide groove 302 to prevent the piston 305 from sliding out of the transverse slide groove 302 and thus limit the movement distance of the limiting slide rod 303. A mating extrusion rod 25 is fixedly installed on the right side of the frame 1, which is used to drive the lifting rod 306 to slide downward by pressing against the right inclined surface of the trapezoidal mating block 307. A push-out rod 23 is fixed on the right side of the frame 1, which is used to extrude the end of the lifting rod 306 and clamp it at the bottom of the moving seat 10 so that the limiting rod 301 slides out of the docking hole 504. A return rod 8 is fixed on the left side of the frame 1, which is used to push the end of the limiting rod 301 back into the transverse slide groove 302.When the movable seat 10 moves to the far left of the frame 1, it is directly below the loading cylinder 4. Since at least two terminal blocks 5 to be processed are stacked inside the loading cylinder 4, the lowest terminal block 5 will be firmly pressed against the top surface of the frame 1 by the combined gravity of all the stacked terminal blocks 5. This ensures that the mating protrusion 12 can be correctly slidably installed with the DIN guide rail groove 505. At the same time, the return push rod 8 will also press the limiting slide rod 303 below the movable seat 10, causing the limiting slide rod 303 to fully retract into the transverse slide groove 302. Since the lifting rod 306 is no longer limited by the limiting slide rod 303 at this time... Therefore, the lifting rod 306 will move upward under the push of the return spring 308, thereby pushing the limiting rod 301 into the mating hole 504 of the terminal block 5 to be processed located above. At this time, the terminal block 5 to be processed located at the bottom of the feeding cylinder 4 will be firmly fixed to the top of the moving seat 10 under the combined action of the mating protrusion 12 and the limiting rod 301. Then the moving seat 10 is pushed by the lead screw motor 6 to the bottom of the punch 20, and the base plate 501 is cut off by the punch 20 to form the processed terminal block 21. Then the processed terminal block 21 will continue to be pushed by the moving seat 10 to the right side of the frame 1, and as the moving seat 10 approaches the right side of the frame 1, the mating rod 306 will move upward under the push of the return spring 308, thereby pushing the limiting rod 301 into the mating hole 504 of the terminal block 5 to be processed located above. The pressing rod 25 presses against the inclined surface on the right side of the trapezoidal mating block 307. As the moving seat 10 continues to move to the right, the pressing rod 25 applies a downward thrust to the inclined surface on the right side of the trapezoidal mating block 307, thereby driving the lifting rod 306 downward and causing the limiting rod 301 to gradually and completely exit the mating hole 504. The moving seat 10 will no longer drive the processed terminal block 21 to move. When the moving seat 10 continues to move to the right, the pressing rod 25 will move above the trapezoidal mating block 307. If the moving seat 10 continues to move to the right at this time, the pressing rod 25 will no longer drive the lifting rod 306 downward, and the push rod will then... The push rod 23 is aligned with the right side of the limiting slide bar 303. When the moving seat 10 continues to move to the right, the push rod 23 will push the left side of the limiting slide bar 303 out of the transverse slide groove 302, so that the limiting slide bar 303 can be locked at the bottom of the moving seat 10. In this way, the limiting slide bar 303 can be used to restrict the upward movement of the lifting rod 306. Then, the moving seat 10 moves to the left under the drive of the lead screw motor 6. At this time, since the lifting rod 306 is restricted by the limiting slide bar 303 and cannot move upward, the limiting push rod 301 will not be inserted into the mating hole 504 of the processed terminal block 21. Therefore, only the moving seat 10 continues to move to the left side of the frame 1. The processed terminal block 21 located on the far right of the frame 1 can be manually removed at this time, or it can be pushed out from the right side of the frame 1 by the next processed terminal block 21 moving to the right, so that the processed terminal block 21 is pushed onto the conveyor belt located on the right side of the frame 1 and transported out, thereby realizing automatic material discharge.

[0035] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 A mounting bracket 14 is fixedly installed on the frame 1, and the stamping push rod 13 is fixed on the mounting bracket 14. A controller 24 is fixedly installed on the mounting bracket 14, and the controller 24 is electrically connected to the lead screw motor 6 and the stamping push rod 13 respectively. A transverse guide rail 26 for guiding the moving seat 10 is fixedly installed on the frame 1, and a grating ruler 11 for detecting the position of the moving seat 10 is fixedly installed between the transverse guide rail 26 and the moving seat 10. The grating ruler 11 is electrically connected to the controller 24. The position of the moving seat 10 can be detected more accurately through the grating ruler 11, thereby ensuring the accuracy of the movement of the moving seat 10 and effectively ensuring the normal operation of the moving seat 10.

[0036] Working Principle: During operation, the stamping and trimming machine provided by this invention continuously transports the stacked terminal blocks 5 to be processed within the loading cylinder 4 to below the punch 20 for processing using the movable base 10, and transports the processed terminal blocks 21 to the right side of the frame 1 for unloading. During this process, the movable base 10 can also automatically fix the terminal blocks 5 to be processed below the loading cylinder 4 via the connecting device 3, and automatically unload the processed terminal blocks 21 from the movable base 10 on the right side of the frame 1. Therefore, during the entire processing, apart from manually stacking the terminal blocks 5 to be processed in the upward material cylinder 4, no manual intervention is required for the positioning, fixing, and transportation of the terminal blocks 5 to be processed, nor for the transportation and unloading of the processed terminal blocks 21. Moreover, the operation of stacking the terminal blocks 5 to be processed in the upward material cylinder 4 can be completely completed by an external robotic arm. Therefore, workers do not need to place their hands directly under the punch 20, ensuring the personal safety of workers. Furthermore, since no workers are required to position, fix, and transport the terminal blocks 5 to be processed, the slow operation of unskilled workers is further avoided from affecting the processing efficiency, which can effectively improve production efficiency and thus achieve safe and efficient edge cutting of the terminal blocks.

[0037] Example 2: Please refer to Figure 1 , Figure 2 and Figure 7Based on Embodiment 1, the output end of the stamping push rod 13 is fixed with a connecting plate 16, and the punch 20 is fixed on the front and rear sides of the connecting plate 16. The bottom of the connecting plate 16 is connected to a limit cover 18 through a compression spring 19. The limit cover 18 is used to clamp the top of the terminal block 5 to be processed to compress and limit it. The top of the limit cover 18 is fixedly installed with a sliding positioning post 17 that is slidably installed with the connecting plate 16. The top of the sliding positioning post 17 is integrally formed with an anti-dislodgement limit cover 15 for limiting the stroke of the sliding positioning post 17. When the punch 20 moves downward under the push of the punching push rod 13, the connecting plate 16 will drive the limiting cover 18 to move downward. The limiting cover 18 will clamp above the terminal block 5 to be processed before the punch 20 contacts the substrate 501. Under the further downward movement of the connecting plate 16 and the compression of the compression spring 19, the terminal block 5 to be processed is pressed tightly. This ensures the accuracy of the position of the terminal block 5 to be processed and avoids deformation of the terminal block 5 to be processed due to the pressure of the punch 20 on the side, which would affect the processing accuracy. Then the punch 20 follows the connecting plate 16 to move downward to complete the punching and cutting of the substrate 501. After the stamping process is completed, the connecting plate 16 moves upward under the drive of the punching push rod 13. At this time, the limiting cover 18 will also move upward under the drive of the connecting plate 16 until it is released from the clamping state with the processed terminal block 21, so that it can wait for the next round of processing.

[0038] Example 3: Please refer to Figure 1 and Figure 10Based on Embodiment 2, a limiting device 2 for preventing the processed terminal block 21 from retracting below the punch 20 is fixedly installed on the right side of the frame 1. The limiting device 2 includes a base 206 fixed to the frame 1 by bolts. A central shaft 201 is integrally formed on the base 206, and a rotating ring 204 is rotatably mounted on the central shaft 201. A torsion spring 205 for resetting the rotating ring 204 to its initial position is installed between the rotating ring 204 and the base 206. A baffle 202 for limiting the movement of the processed terminal block 21 to the left is integrally formed on the rotating ring 204, and a limiting post 203 for limiting the left rotation position of the baffle 202 is fixedly installed on the base 206. After the processed terminal block 21 is transported to the far right of the frame 1 by the movable seat 10, although the limiting rod 301 has disengaged from the processed terminal block 21, the cooperating protrusion 12 and the top of the movable seat 10 may, under the action of friction, drive the processed terminal block 21 back to the left. Therefore, a limiting device 2 is needed to restrict the processed terminal block 21 from moving to the left. Specifically, when the movable seat 10 drives the processed terminal block 21 to move to the right, the right side of the processed terminal block 21 will push the baffle 202 to rotate to the right to a non-working position. At this time, the processed terminal block 21 can pass smoothly through... After the processed terminal block 21 has completely passed the limit device 2, the baffle 202 will rotate to the left again under the action of the torsion spring 205 and press against the limit post 203. At this time, if the processed terminal block 21 wants to move to the left, it will collide with the right side of the baffle 202. Since the baffle 202 is restricted by the limit post 203 and cannot rotate to the left, it will prevent the processed terminal block 21 from continuing to move to the left, thus achieving the purpose of not allowing the processed terminal block 21 to move to the left. This can prevent the processed terminal block 21 from returning to the bottom of the punch 20 and interfering with normal production, thus ensuring production safety.

[0039] Example 4: Please refer to Figures 1 to 4 Based on Embodiment 3, the front and rear sides of the frame 1 are provided with discharge ports 27 at the positions corresponding to the punches 20 to facilitate the discharge of the cut substrates 501. The frame 1 also has integrally formed discharge ramps 9 for guiding the cut substrates 501 into the discharge ports 27. Protective plates 7 are fixed on the left and right sides of the corresponding discharge ports 27 to prevent the substrates 501 and cutting debris from falling onto the frame 1. The cut substrates 501 will fall along the discharge ramps 9 into the discharge ports 27 under their own weight and the lateral pressure provided by the punches 20 during cutting, and then be collected by a collecting device located below the discharge ports 27. This prevents the cut substrates 501 from accumulating on the frame 1, thus ensuring continuous stamping and cutting operations.
