Description

Technical Field

[0001] The present invention relates to the technical field of terminal strip, and specifically to a stamping device for terminal strip. Background Art

[0002] Background Art: The basic use of a stamping device for terminal strip is to stamp the terminal strip to produce electronic components such as terminals and connectors that meet the specification requirements. This device is widely used in fields such as electronics, automotive, home appliances, and communication. Especially when mass-producing products such as connectors and terminals, it provides an efficient and precise solution.

[0003] However, the existing stamping devices for terminal strip have the following problems during the stamping process of the terminal strip:

[0004] Problem 1: The existing stamping devices for terminal strip usually need to set up a stamping structure and a feeding structure, and the stamping structure and the feeding structure are usually set in two parts of the device, which respectively occupy different spaces, possibly resulting in low utilization rate of the production line space.

[0005] Based on Problem 1, Problem 2 is proposed: The molds of the existing stamping structures are relatively single. The single molds are usually only suitable for one product or a specific production process, lacking the adaptability to multiple products or processes. The single molds need to be customized according to the different requirements of each product, which will lead to high costs for mold design and production.

[0006] Based on Problem 1, Problem 3 is proposed: The stamping structure and the feeding structure need to cooperate simultaneously. While feeding, the terminal strip is stamped. However, it needs to be considered that after the mold stamps the terminal strip, the mold needs to retract and disengage from the punching hole. At this time, the feeding structure continues to feed. During the disengagement process, due to the friction between the mold and the punching hole, it will cause the terminal strip to warp, thus resulting in the problem of stretching and damage to the punching hole by the mold. In view of the above problems, the inventor proposes a stamping device for terminal strip to solve the above problems. Summary of the Invention

[0007] In order to solve the problem of low utilization rate of the space occupied by the stamping structure and the feeding structure; the purpose of the present invention is to provide a stamping device for terminal strip.

[0008] To solve the above technical problems, the present invention adopts the following technical solutions: a frame and a strip. A bracket is fixedly connected to the outer wall of the frame. A motor is installed on the bracket. A rotating wheel is installed on the output shaft of the bracket. A plurality of grooves are provided on the rotating wheel, and a limiting groove is provided on the inner wall of the rotating wheel.

[0009] A quick-release assembly is installed on the rotating wheel, and a plurality of stamping assemblies are installed on the quick-release assembly. The stamping assemblies pass through the grooves. The quick-release assembly is used to quickly replace the stamping assemblies. The stamping assemblies perform circular motion as the rotating wheel and the quick-release assembly rotate.

[0010] A plurality of transmission belts are arranged on the output shaft of the motor and on the frame, and the plurality of transmission belts are connected to each other in transmission, one of the transmission belts is connected to the output shaft of the motor, a roller is installed on the output shaft of the transmission belt, and two transmission belts are arranged between two of the rollers;

[0011] A gap is left between the two conveyor belts, and a belt groove is opened on the outer wall of the conveyor belt, and the material belt moves between the two belt grooves;

[0012] The two ends of the conveyor belt are respectively equipped with abdominal pressure components, which cooperate with the belt groove to allow the material belt to move smoothly;

[0013] An auxiliary structure is provided on the outer wall of the stamping assembly, which is used to prevent the material strip from warping during the stamping retraction process of the stamping assembly;

[0014] A collection box for collecting waste is fixedly connected to the outer wall of the frame;

[0015] The collecting box is located at the bottom of the conveyor belt and is used to support the conveyor belt;

[0016] Through the above technical solution, the motor is started, and the roller is driven to rotate through the transmission belt, and the rotating wheel is rotated at the same time. The rotation of the roller drives the conveyor belt to run, and the abdominal pressure component assists the material belt to move smoothly in the belt groove of the conveyor belt. The rotating wheel drives the stamping component to make a circular motion. The stamping component punches the material belt at the appropriate position. Its auxiliary structure prevents the material belt from tilting when stamping back. The collection box collects the waste generated by stamping while supporting the conveyor belt.

[0017] Preferably, the quick-release assembly comprises a connecting block, the connecting block is plugged into the inner wall of the rotating wheel, a groove is provided on the inner wall of the rotating wheel, two L-shaped rods are slidably connected to the inner wall of the connecting block, a third spring is connected between one ends of the two L-shaped rods, and the other ends of the two L-shaped rods are clamped on the inner wall of the groove;

[0018] Through the above technical solution, when the quick-release assembly needs to be disassembled, external force is applied to the L-shaped rod to overcome the elastic force of the third spring, so that the L-shaped rod is disengaged from the limiting groove, and the connecting block can be removed from the rotating wheel, thereby driving the stamping assembly to be taken out from the inside of the rotating wheel, thereby achieving convenient replacement.

[0019] Preferably, a plurality of screw holes are formed in the outer wall of the connecting block, and the stamping assembly includes a connecting rod, and one end of the connecting rod is threadedly connected to the inner wall of the screw hole;

A cavity is formed between the top of the movable seat and the bottom of the connecting rod. A spring is arranged inside the cavity. An oil inlet is arranged on the outer wall of the bottom of the connecting rod, and a channel is arranged at the bottom of the connecting rod;

[0021] Through the above technical solution, when the stamping assembly moves towards the conveyor belt, the top of the movable seat is forced to compress the first spring and squeeze the hydraulic oil inside the cavity. The oil inlet on the connecting rod is used to add hydraulic oil into the cavity and seal it. Subsequently, the hydraulic oil pushes the stamping block to move downward through the channel.

[0022] Preferably, a connecting seat is connected to the bottom of the connecting rod. A stamping block is slidably connected to the inner wall of the channel. The stamping block extends to the middle of the connecting seat. A second spring is installed inside the connecting seat. The extended end of the outer wall of the stamping block is located on the top of the second spring;

[0023] Through the above technical solution, the stamping block moves downward to compress the spring, and the stamping block moves to the outside of the movable seat to punch the passing strip.

[0024] Preferably, the two auxiliary structures are respectively installed on the outer walls at both ends of the movable seat.

One end of the fourth spring is connected to the outer wall of the fixing plate. The rotating plate is rotatably connected to the outer wall of the movable seat. The other end of the fourth spring is connected to the outer wall of the rotating plate. The two wheels are respectively rotatably connected to the outer wall of the rotating plate;

[0025] Through the above technical solution, during the process of the movable seat approaching, approaching and then moving away from the strip, the tension of the fourth spring makes the rotating plate and the wheel approach and close to the surface of the strip. The purpose is to keep the strip flat in the trough, preventing one end of the strip from being lifted when the stamping assembly moves in a circular motion and disengages from the punching;

[0026] When the wheel completely moves away from the strip, at this time the strip moves to the lower part of the elastic pressing strip, and the elastic pressing strip keeps the strip flat, so as to keep the strip flat and not warped or deformed during and after the processing.

[0027] Preferably, two support rods are fixedly connected to the top port of the collection box, and two discharge ports are formed in the outer wall of the collection box;

[0028] Through the above technical solution, the support rod at the top of the collection box supports the extrusion of the strip, the movable seat and the conveyor belt, preventing the conveyor belt from being sunken due to extrusion. The generated waste falls into the interior of the collection box through the gaps of the conveyor belt for collection, and finally is discharged through the discharge port of the collection box.

[0029] Preferably, a punching hole is provided at one end of the strip, and the punching block completes the punching.

[0032] Preferably, a return spring is arranged inside the chute groove of the connecting frame, and the return spring is above the movable rod;

[0033] Through the above technical solution, when the strip moves on the conveyor belt, the roller shaft applies a certain pressure to the strip under the pressure of the return spring, making the strip fit more tightly in the groove of the conveyor belt to ensure the smooth movement of the strip. When the thickness of the strip changes, the movable rod can slide in the chute groove of the connecting frame, and the return spring adjusts the pressure according to the situation to adapt to the change of the strip.

[0034] Preferably, two elastic pressing strips are fixedly connected to the outer wall of the connecting frame. By adopting the above technical solution, when the strip moves on the conveyor belt, the two elastic pressing strips assist a certain pressure to the strip, making the strip fit flat on the conveyor belt.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] 1. Through the settings of the rotating wheel, the quick-release component and the stamping component, the quick-release component is used to install the stamping component on the rotating wheel, which is convenient for installing and replacing the stamping component, thereby improving the adaptability and application range of the stamping component. During the process of driving the stamping component to make a circular motion and rotate, it cooperates with the conveyor belt to convey the strip. Through the close combination of the stamping component with other components, the overall occupied area of the equipment is reduced, and the stamping function and the feeding function are integrated together, which not only reduces the waste of space, but also improves the overall compactness and efficiency of the equipment.

[0037] 2. Through the setting of the auxiliary structure, the auxiliary structure includes a fixing plate, a fourth spring, a rotating plate and a wheel. During the process of the movable seat approaching, approaching and then moving away from the strip, the tension of the fourth spring causes the rotating plate and the wheel to approach and adhere to the surface of the strip. The purpose is to keep the strip flat in the groove, prevent one end of the strip from being lifted when the stamping component moves in a circular motion and disengages from the punching hole. When the wheel completely moves away from the strip, at this time the strip moves to the lower part of the elastic pressing strip, and the elastic pressing strip keeps the strip flatly pressed, so as to keep the strip flat and not warped or deformed during and after the processing.

[0038] 3. Through the setting of the abdominal pressure component, the roller shaft and the conveyor belt convey the strip. When the strip moves on the conveyor belt, the roller shaft applies a certain pressure to the strip under the pressure of the return spring, so that the strip fits more closely in the groove of the conveyor belt, ensuring the smooth movement of the strip. When the thickness of the strip changes, the movable rod can slide in the chute of the connecting frame, and the return spring adjusts the pressure according to the situation to adapt to the change of the strip.

[0062] A gap is left between the two conveyor belts 16. A belt groove 1601 is provided on the outer wall of the conveyor belt 16. The strip 7 moves between the two belt grooves 1601;

[0063] Abdominal pressure components 5 are respectively installed at both ends of the conveyor belt 16. The abdominal pressure components 5 cooperate with the belt groove 1601 to make the strip 7 move smoothly;

[0064] An auxiliary structure is provided on the outer wall of the stamping component 4 to prevent the strip 7 from being lifted during the stamping and retracting process of the stamping component 4;

[0065] A collection box 6 for collecting waste materials is fixedly connected to the outer wall of the frame 1;

[0066] The collection box 6 is located at the bottom of the conveyor belt 16 and is used to support the conveyor belt 16;

[0067] Through the above technical solution, when the motor 9 is started, the roller 11 is driven to rotate through the drive belt 10, and at the same time the rotating wheel 3 is rotated. The rotation of the roller 11 drives the conveyor belt 16 to run. The abdominal pressure component 5 assists the strip 7 to move smoothly in the belt groove 1601 of the conveyor belt 16.

[0068] Embodiment 2

[0069] As Figures 1 - 12As shown, the quick-release component 8 includes a connecting block 801. The connecting block 801 is inserted into the inner wall of the rotating wheel 3. A groove 301 is formed on the inner wall of the rotating wheel 3. Two L-shaped rods 803 are slidably connected to the inner wall of the connecting block 801. A third spring 804 is connected between one ends of the two L-shaped rods 803. The other ends of the two L-shaped rods 803 are clamped on the inner wall of the groove 301;

[0070] Through the above technical solution, when it is necessary to disassemble the quick-release component 8, an external force is applied to the L-shaped rod 803 to overcome the elastic force of the third spring 804, so that the L-shaped rod 803 is disengaged from the limiting groove 302, and then the connecting block 801 can be disassembled from the rotating wheel 3, thereby driving the stamping component 4 to be taken out from the inside of the rotating wheel 3, so as to achieve convenient replacement.

[0071] A plurality of screw holes 802 are formed on the outer wall of the connecting block 801. The stamping component 4 includes a connecting rod 401. One end of the connecting rod 401 is threadedly connected to the inner wall of the screw hole 802;

[0072] The bottom of the connecting rod 401 is slidably connected with a movable seat 402. The movable seat 402 is arranged as an arc-shaped block. A cavity is formed between the top of the movable seat 402 and the bottom of the connecting rod 401. A first spring 403 is arranged inside the cavity. An oil inlet is arranged on the outer wall of the bottom of the connecting rod 401. A channel 4010 is arranged at the bottom of the connecting rod 401;

[0073] Through the above technical solution, when the stamping component 4 moves towards the conveyor belt 16, the top of the movable seat 402 is compressed by the force and the hydraulic oil inside the cavity is squeezed. The oil inlet on the connecting rod 401 is used to add hydraulic oil into the cavity and seal it. Then the hydraulic oil pushes the stamping block 406 to move downward through the channel 4010.

[0074] A connecting seat 404 is connected to the bottom of the connecting rod 401. A stamping block 406 is slidably connected to the inner wall of the channel 4010. The stamping block 406 extends to the middle of the connecting seat 404. A second spring 405 is installed inside the connecting seat 404. The extended end of the outer wall of the stamping block 406 is at the top of the second spring 405;

[0075] Through the above technical solution, the stamping block 406 moves downward to compress the spring. The stamping block 406 moves to the outside of the movable seat 402 to punch the passing strip 7.

[0076] Two auxiliary structures are respectively installed on the outer walls at both ends of the movable seat 402. The auxiliary structure includes a fixing plate 12, a fourth spring 13, a rotating plate 14 and a wheel 15. The fixing plate 12 is fixedly connected to the outer wall of the movable seat 402. One end of the fourth spring 13 is connected to the outer wall of the fixing plate 12. The rotating plate 14 is rotatably connected to the outer wall of the movable seat 402. The other end of the fourth spring 13 is connected to the outer wall of the rotating plate 14. Two wheels 15 are respectively rotatably connected to the outer wall of the rotating plate 14;

[0077] Through the above technical solution, during the process of the movable seat 402 approaching, getting close to and then moving away from the strip 7, the tension of the fourth spring 13 makes the rotating plate 14 and the wheels 15 approach and get close to the surface of the strip 7. The purpose is to keep the strip 7 flat in the tape groove 1601 and prevent one end of the strip 7 from being lifted when the stamping assembly 4 moves in a circular motion and disengages from the punching hole 701;

[0078] When the wheels 15 are completely away from the strip 7, at this time the strip 7 moves to the lower part of the elastic pressing strip 17, and the elastic pressing strip 17 keeps the strip 7 under flat pressure, so as to keep the strip 7 flat and not warped or deformed during and after the processing.

[0079] Two support rods 601 are fixedly connected to the top port of the collection box 6, and two discharge ports are opened on the outer wall of the collection box 6;

[0080] Through the above technical solution, the support rods 601 at the top of the collection box 6 support the extrusion of the strip 7, the movable seat 402 and the conveyor belt 16, prevent the conveyor belt 16 from being sunken due to extrusion, and the generated waste materials fall into the interior of the collection box 6 through the gaps of the conveyor belt 16 for collection, and are finally discharged through the discharge port of the collection box 6.

[0081] One end of the strip 7 is provided with a punching hole 701, which is punched by the punching block 406.

[0082] Embodiment III

[0083] As Figure 16 shown, the abdominal pressure assembly 5 includes a connecting frame 501. The connecting frame 501 is fixedly connected to the outer wall of the frame 1 and is above the conveyor belt 16. Chute grooves are respectively arranged at both ends of the connecting frame 501. A movable rod 502 is slidably connected between both ends of the connecting frame 501. A roller shaft 503 is rotatably connected to the outer wall of the movable rod 502. The roller shaft 503 is on the upper surface of the conveyor belt 16;

[0084] Through the above technical solution, the roller shaft 503 and the conveyor belt 16 convey the strip 7.

[0085] A return spring 504 is arranged inside the chute groove of the connecting frame 501, and the return spring 504 is above the movable rod 502;

[0086] Through the above technical solution, when the strip 7 moves on the conveyor belt 16, the roller shaft 503 applies a certain pressure to the strip 7 under the pressure of the return spring 504, so that the strip 7 fits more tightly in the groove 1601 of the conveyor belt 16, ensuring the stable movement of the strip 7. When the thickness of the strip 7 changes, the movable rod 502 can slide in the chute of the connecting frame 501, and the return spring 504 adjusts the pressure according to the situation to adapt to the change of the strip 7.

[0087] Two elastic pressing strips 17 are fixedly connected to the outer wall of the connecting frame 501. Through the above technical solution, when the strip 7 moves on the conveyor belt 16, the two elastic pressing strips 17 assist a certain pressure to the strip 7, so that the strip 7 fits flatly on the conveyor belt 16.

[0088] Working principle: When the work starts, the motor 9 is started. The output shaft of the motor 9 drives the conveyor belt 10 and the rotating wheel 3 to rotate. During the rotation of the rotating wheel 3, the quick-release assembly 8 is driven to rotate, and the stamping assembly 4 makes a circular motion accordingly. During the operation of the conveyor belt 10, the roller 11 rotates and drives the conveyor belt 16 to operate at the same time. When the strip 7 moves on the conveyor belt 16, the roller shaft 503 applies a certain pressure to the strip 7 under the pressure of the return spring 504, so that the strip 7 fits more tightly in the groove 1601 of the conveyor belt 16, ensuring the stable movement of the strip 7. When the thickness of the strip 7 changes, the movable rod 502 can slide in the chute of the connecting frame 501, and the return spring 504 adjusts the pressure according to the situation to adapt to the change of the strip 7;

[0089] The gap between the two conveyor belts 16 facilitates the passage of the stamping block 406 and prevents the stamping block 406 from affecting the movement of the conveyor belt 16. When the stamping assembly 4 moves towards the conveyor belt 16, the movable seat 402 is stressed and the top compresses the first spring 403 and squeezes the hydraulic oil inside the cavity. The oil inlet on the connecting rod 401 is used to add hydraulic oil into the cavity and seal it. Subsequently, the hydraulic oil pushes the stamping block 406 to move downward through the channel 4010. The stamping block 406 moves downward and squeezes the spring. The stamping block 406 moves to the outside of the movable seat 402 and punches the passing strip 7. During this process, the support rod 601 on the top of the collection box 6 supports the extrusion of the strip 7, the movable seat 402 and the conveyor belt 16, preventing the conveyor belt 16 from being sunken due to extrusion;

[0090] When the punching is completed, the movable seat 402 gradually moves away from the strip 7, the pressure on the top of the movable seat 402 gradually decreases, the first spring 403 and the second spring 405 gradually return to their original positions, and the second spring 405 drives the stamping block 406 to return to its original position and push the hydraulic oil back into the cavity. During this process, with the change of pressure, after the stamping block 406 punches the strip 7, it immediately retracts, reducing the stretching of the punched hole 701 of the strip 7;

[0091] During the process of the movable seat 402 approaching, being close to, and then moving away from the strip 7, the tension of the fourth spring 13 causes the rotating plate 14 and the wheel 15 to approach and be close to the surface of the strip 7, aiming to keep the strip 7 flat in the belt groove 1601 and prevent one end of the strip 7 from being lifted when the circular motion of the stamping assembly 4 disengages from the punching hole 701.

[0092] When the wheel 15 completely moves away from the strip 7, at this time the strip 7 moves below the elastic pressing strip 17, and the elastic pressing strip 17 keeps the strip 7 flatly pressed, so as to keep the strip 7 flat and not warped or deformed during and after the processing.

[0093] In addition, the rotating wheel 3 is provided with a number of grooves 301, and a number of stamping assemblies 4 can be installed on the quick-release assembly 8. According to different requirements, different numbers of stamping assemblies 4 can be installed, and the spacing can be adjusted to suit different processing requirements. At the same time, when it is necessary to disassemble the quick-release assembly 8, an external force is applied to the L-shaped rod 803 to overcome the elastic force of the third spring 804, so that the L-shaped rod 803 is disengaged from the limiting groove 302, and then the connecting block 801 can be disassembled from the rotating wheel 3, thereby driving the stamping assembly 4 to be taken out from the inside of the rotating wheel 3, so as to achieve convenient replacement.

[0094] The generated waste materials fall into the interior of the collection box 6 through the gaps of the conveyor belt 16 for collection, and are finally discharged through the discharge port of the collection box 6.

[0095] All the standard parts used in the present invention can be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt the mature conventional means such as bolts, rivets, and welding in the prior art. The machines, parts, and equipment all adopt the conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0096] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
