Description

A transmission device for cable stripping and tinning. Technical Field

[0001] This utility model relates to a transmission device, and more particularly to a transmission device for cable stripping and tinning. Background Technology

[0002] In the processing of wires and cables, wire stripping and tinning are common procedures. Wire stripping precisely removes the insulation from the ends to expose the conductor, while tinning forms a uniform tin layer on the conductor surface. This prevents conductor oxidation, improves connection reliability, and makes it easier for the conductor to bond with other components during soldering or crimping, thereby significantly reducing the risk of connection failure.

[0003] Currently, wire stripping and tinning processes are mostly performed independently, typically requiring separate wire stripping and tinning equipment. During processing, the wire stripping equipment first treats the cable ends, then the stripped cable is transported to the tinning equipment, where the tinning process is completed. The advantage of this method is that the equipment itself has a simple structure, and it is relatively easy to adjust the parameters of the wire stripping or tinning equipment individually for different cable specifications. It is also suitable for small-batch, scattered cable processing.

[0004] However, this processing method has significant drawbacks: because the two processes are independent of each other, the cable transfer between processes not only increases labor costs but also leads to loose connections between processes due to differences in transfer rhythm, resulting in a longer waiting time in the overall processing flow. Furthermore, during transfer, cables may be bent or collided due to improper storage, causing damage and adversely affecting the processing quality. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the objective is to provide a transmission device for cable stripping and tinning.

[0006] The technical implementation scheme of this utility model is as follows: A transmission device for cable stripping and tinning includes a main body, a workbench, a mounting base, a fixing plate, a drive motor, a transmission component, a clamp, an X-shaped hinge frame, a push rod, a support block, a clamp, a return spring, and a top rod. The mounting base is located at the rear of the main body for mounting the stripping and tinning components. A workbench is mounted on the upper part of the main body. Two fixing plates are fixedly installed at the rear of the main body, and a transmission component is located between the two fixing plates. The transmission component consists of two transmission wheels and a transmission belt wound around the two transmission wheels. A drive motor is located on one side of the fixing plate, and the output shaft of the drive motor is connected to one of the transmission wheels of the transmission component. The drive motor drives the transmission component to rotate clockwise. The right side of the transmission component extends outward from inside the main body. Several clamps are evenly spaced on the outer edge of the transmission belt, and each clamp contains an X-shaped hinge frame. The X-type hinge frame consists of a hinge shaft mounted on a clamp and two rotatably mounted on the hinge shaft. Each support rod has a vertical push rod at both ends. Each clamp has two sliding and symmetrical clamping blocks in its upper part, which work together to clamp the cable. Each clamp has guide grooves on its lower front and rear sides. The push rods on each support rod of the X-type hinge frame extend into the guide grooves in the lower part of the clamp. One of the clamps has a return spring at its lower part, and the other end of the return spring is connected to the clamp. One of the clamps in each clamp has a push rod at its upper rear end. The right rear part of the equipment body has a release mechanism. When the clamp moves with the transmission component, when the clamp moves to the lower right part of the transmission component, the release mechanism can interact with the push rod on the corresponding clamp to push the push rod, thereby causing the clamp corresponding to the push rod to release the clamped cable, allowing the cable to fall to the right area of ​​the equipment body.

[0007] Furthermore, the release mechanism includes a drive motor, a swing arm, and a connecting rod. The drive motor is located at the rear right side of the main body of the equipment. The output shaft of the drive motor is equipped with a swing arm, and the end of the swing arm is equipped with a connecting rod. The drive motor can drive the swing arm to swing back and forth. During the swing of the swing arm with the drive motor, the connecting rod will rotate in an arc with the swing arm.

[0008] Furthermore, it also includes a fixed frame and limiting guide rails. A fixing clamp is connected to the mounting base. The front of the fixed frame is provided with two limiting guide rails. Each limiting guide rail consists of a horizontal bar set horizontally above the worktable, with a wire transmission interval between it and the worktable, and an arc-shaped bar connected to the right end of the horizontal bar. The lower end of the arc-shaped bar extends to one side of the transmission component.

[0009] Furthermore, it also includes a receiving hopper, which is located on the lower right side of the main body of the equipment.

[0010] Furthermore, it also includes flexible pads, with flexible pads provided on the opposite sides of the two clamps in the same clamp.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The present invention sets the wire stripping and tinning processes on the same station through the transmission component and the mounting base. During processing, the transmission component drives the clamping block and the clamped cable to flow in an orderly manner, so that the cable can be directly transported to the corresponding position of the tinning process after the wire stripping is completed, which reduces the waiting and transfer time between processes and improves the overall continuity and processing efficiency of the cable end processing.

[0012] 2. This utility model, through its designed unclamping mechanism, can push the clamping block and unclamp the cable by the contact and disengagement of the connecting rod and the top rod when the clamping seat rotates to the corresponding position. The cable can be automatically unclamped without manual operation, reducing the degree of human intervention. It can also stably match the operating rhythm of the transmission components, ensuring the smoothness and reliability of the unclamping process.

[0013] 3. This utility model effectively guides the processed end and middle area of ​​the cable through the setting of the limiting guide rail, reducing the deviation or shaking of the cable during transmission and processing, which helps to ensure the accuracy of wire stripping, tinning and clamping operations.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] A transmission device for cable stripping and tinning, as shown in Figures 1-4, includes a main body 1, a workbench 2, a mounting base 3, a fixing plate 4, a drive motor 41, a transmission component 42, a clamp 5, an X-shaped hinge frame 51, a guide groove 5100, a push rod 511, a support block 52, a clamping block 53, a return spring 54, and a push rod 55. The mounting base 3 is fixedly installed at the rear of the main body 1. This mounting base 3 is used to install the stripping component and the tinning component. The mounting base 3 has a pre-reserved mounting area adapted to the stripping component and the tinning component. A traditional stripping structure can be fixed to the mounting base 3 through the mounting area, allowing it to be customized according to processing requirements. The cable sheath and outer layer of the core wire are stripped to expose part of the conductor at the end of the core wire. The specific structure can be customized according to processing requirements, and the existing technology is relatively mature. The tinning component consists of a rosin container, a tin liquid container, and a pressing component installed at the bottom of the mounting base 3. The pressing component is detachably connected to the mounting base 3, and its operation is linked to the control module inside the main body of the equipment 1. When the transmission component 42 drives the cable to the corresponding position, the control module will trigger the pressing component to operate, so that the cable end passes through the rosin container to complete the rosin application and through the tin liquid container to complete the tinning during the transmission, ensuring the pretreatment effect before tinning and the tinning quality. A workbench 2 is fixedly installed on the upper part of the main body of the equipment 1 by bolts. The surface of the workbench 2 is adapted to the transmission path of the transmission component 42 and can provide support for the cable below. Two relatively parallel fixed plates 4 are fixedly installed at the rear of the main body 1 of the equipment. A transmission component 42 is rotatably installed between the two fixed plates 4 via a bearing. The transmission component 42 consists of two transmission wheels and a transmission belt wrapped around the two transmission wheels. The two ends of the wheel axles of the two transmission wheels are fixedly connected to the inner rings of the bearings on the two fixed plates 4 to ensure stable rotation of the transmission wheels.

[0023] A drive motor 41 is fixedly mounted on the outer wall of one of the fixed plates 4 via a motor mount. The output shaft of the drive motor 41 passes through the shaft hole on the fixed plate 4 and is coaxially and fixedly connected to the axle of one of the transmission wheels of the transmission component 42. The drive motor 41 is electrically connected to the control module inside the main body 1 of the equipment. The control module can control the drive motor 41 to achieve intermittent operation, that is, the drive motor 41 drives the transmission component 42 to rotate clockwise for a corresponding distance and then stops. The stopping position corresponds to the processing position of the wire stripping component and the tinning component, and the stopping time can be reserved for the processing time of wire stripping and tinning, so as to ensure that the cable can be fully processed at the corresponding work station. The right side of the transmission component 42 extends outward from inside the main body 1. Several clamps 5 are evenly spaced on one side of the outer edge of the transmission belt. The clamps 5 are fixedly connected to the transmission belt by screws and rotate synchronously with the transmission belt. Each clamp 5 has an X-shaped hinge frame 51 located in the center. The X-shaped hinge frame 51 consists of a hinge shaft located in the middle of the inner wall of the clamp 5 and two support rods rotatably mounted on the hinge shaft. The two support rods are cross-rotating around the hinge shaft. Each support rod has a push rod 511 vertically welded to both ends, and the push rod 511 is perpendicular to the support rod. Each clamp 5 has a horizontal slide rail in the upper part. Two clamping blocks 53 are symmetrically arranged on the slide rail and can slide relative to or away from each other along the slide rail to clamp the cable end. The clamping block 53 has an arc-shaped groove on the side closest to the cable to improve the stability of the clamping. Each clamping block 53 has guide grooves 5100 on both the front and rear sides of its lower part. The guide grooves 5100 are inclined. The push rods 511 on each support rod of the X-shaped hinge frame 51 extend into the guide grooves 5100 at the lower part of the clamping block 53. When the two support rods of the X-shaped hinge frame 51 rotate around the hinge axis, the push rods 511 slide in the guide grooves 5100 and push the clamping block 53 to move along the slide rail. One of the clamping blocks 53 is provided with a return spring 54 at its lower part. The other end of the return spring 54 is fixedly connected to the inner wall of the clamping seat 5. When the push rods 511 push the clamping blocks 53 away from each other, the return spring 54 is in a stretched state. When the pushing force of the push rods 511 disappears, the return spring 54 can pull the clamping block 53 to return to its original position, realizing the automatic return of the clamping block 53. One of the clamping blocks 53 in each clamping seat 5 has a top rod 55 integrally formed at the rear end of its upper part. The top rod 55 extends outward to the outside of the clamping seat 5. The device body 1 is equipped with a release mechanism at the right rear. When the clamp 5 moves with the transmission component 42, when the clamp 5 moves to the lower right of the transmission component 42, the release mechanism can interact with the push rod 55 on the corresponding clamp 5 to push the push rod 55, thereby causing the clamping block 53 corresponding to the push rod 55 to slide away from the other clamping block 53, releasing the clamped cable and letting the cable fall into the preset collection area in the right area of ​​the device body 1, thus completing the automatic unloading.

[0024] As shown in Figures 2 and 5, the unclamping mechanism includes a drive motor 7, a swing arm 71, and a connecting rod 72. The drive motor 7 is fixedly mounted on the right rear part of the main body 1 via a motor bracket. The drive motor 7 is electrically connected to the control module inside the main body 1. The control module can control the start, stop, and direction of the drive motor 7 according to the intermittent operation state of the transmission component 42, so that the action of the drive motor 7 is coordinated with the stopping period of the transmission component 42. A swing arm 71 is fixedly connected to the output shaft of the drive motor 7 via a key. A connecting rod 72 is rotatably connected to the end of the swing arm 71 via a pin. The connecting rod 72 can rotate slightly around the pin to adapt to the contact angle with the top rod 55. The drive motor 7 can drive the swing arm 71 to swing back and forth. During the swing of the swing arm 71 with the drive motor 7, the connecting rod 72 will move in an arc with the swing arm 71. When the clamp 5 moves to the lower right part of the transmission component 42 and the transmission component 42 is in a stopped state, the control module triggers the drive motor 7 to run, so that the arc-shaped connecting rod 72 first contacts the top rod 55 on the corresponding clamp 5 and pushes the top rod 55. The top rod 55 drives the corresponding clamp block 53 to move. As the swing arm 71 continues to swing, the connecting rod 72 gradually disengages from the top rod 55. At this time, the clamp block 53 is reset under the action of the return spring 54, thereby realizing the pushing and disengaging process of the top rod 55, which precisely corresponds to the intermittent flow mentioned above, ensuring that the disengagement action is stable and reliable.

[0025] When the transmission device is working, the end of the cable to be processed needs to be placed between the two clamping blocks 53 of the clamping seat 5. Pulling one clamping block 53 causes the push rod 511 in contact with it to slide in the guide groove 5100 at the bottom of the clamping block 53, thereby causing the two support rods of the X-shaped hinge frame 51 to rotate around the hinge axis, pushing the two clamping blocks 53 to move relative to each other along the slide rail, so that the clamping blocks 53 move away from each other. At this time, the return spring 54 is in the corresponding stretched state. The end of the cable is placed in the clamping block 53, and after placing one end of the cable, the clamping block 53 is released, and the return spring 54 pushes the clamping block 53 to return to its original position. Subsequently, the control module controls the drive motor 41 to operate, and the drive motor 41 drives the transmission component 42 to rotate intermittently clockwise. The clamping seat 5 on the transmission component 42 moves synchronously with the transmission belt, thereby driving the clamped cable to pass through the corresponding workstations of the wire stripping component and the tin-dipping component on the mounting base 3 in sequence. When the transmission component 42 reaches the corresponding position, it stops, allowing processing time: the wire stripping component strips the wire at the cable end, exposing the conductor; then the transmission component 42 continues to move to the tin-immersion station and stops. The control module triggers the pressing component of the tin-immersion component to move, causing the cable end to pass through the rosin container to complete the rosin application and through the tin liquid container to complete the tin immersion; during continuous processing, the transmission component 42 drives the clamp 5 to gradually move to the lower right. At this time, the control module controls the drive motor 7 of the release mechanism to operate, and the drive motor 7 drives the swing arm 71 to swing, and the connecting rod 72 at the end of the swing arm 71 follows the arc. The cable is rotated and contacts the push rod 55 on the clamp 5, pushing the push rod 55. The push rod 55 drives the corresponding clamp 53 to move away from the other clamp 53, releasing the clamp on the cable. The cable falls to the collection area on the right side of the main body 1. Then the drive motor 7 continues to drive the swing arm 71 to swing, the connecting rod 72 disengages from the push rod 55, and the clamp 53 resets under the action of the return spring 54, waiting for the next clamping operation. After the clamped block continues to run, the drive motor 7 is controlled to drive the swing arm 71 to reset, thus completing the continuous processing and transmission process of cable stripping and tinning in a cycle.

[0026] Example 2

[0027] Based on Embodiment 1, as shown in Figures 1 and 2, it also includes a fixing frame 6 and limiting guide rails 61. A fixing clip is detachably connected to the mounting base 3 via bolts. The clamping jaws of the fixing clips are adapted to the side of the fixing frame 6, and the fixing frame 6 is securely connected to the mounting base 3 via the fixing clips. This connection method facilitates adjusting the installation position of the fixing frame 6 according to cable processing requirements. The front of the fixing frame 6 has two integrally formed limiting guide rails 61. Each limiting guide rail 61 consists of a horizontal bar positioned above the worktable 2 and an arc-shaped rod welded to the right end of the horizontal bar. A cable transmission gap is left between the horizontal bar and the worktable 2. The height of this gap is slightly larger than the diameter of the cable, which can prevent the cable from... During transmission, friction with the surface of the worktable 2 causes scratches to the outer sheath. Two limiting guide rails 61 are used to guide the processed end and the middle area of ​​the cable, respectively. When the cable enters the processing flow, its processed end can pass under the crossbar of the corresponding limiting guide rail 61, while the middle area is placed under the crossbar of the other limiting guide rail 61. The crossbar provides a downward limiting effect on the cable to prevent the cable from swinging and deviating significantly due to movement friction. The lower end of the arc-shaped rod extends to one side of the transmission component 42, and the curvature of the arc-shaped rod is adapted to the path of the cable moving towards the clamp 5, which can provide lateral guidance to the end of the cable. At the same time, near the unclamping mechanism, the cable is released from its restriction to ensure normal cable feeding.

[0028] As shown in Figure 2, the device also includes a receiving hopper 8. A bracket is welded to the lower right part of the main body 1. The bottom of the receiving hopper 8 is bolted to the bracket. The opening of the receiving hopper 8 is flared and faces the lower position of the clamp 5 when it is rotated to the lower right. Several pads are arranged at intervals in the lower inner part of the receiving hopper 8. The pads are horizontally set and their two ends are fixedly connected to the inner side wall of the receiving hopper 8. There is a gap between the bottom of the pad and the bottom of the receiving hopper. When the clamp 5 releases the cable, the cable can fall directly onto the pad under the action of gravity, avoiding direct contact between the cable and the bottom of the receiving hopper. The gap allows the hand or tool to be inserted to easily remove the cable from the receiving hopper 8. The inner side wall of the receiving hopper 8 is provided with a rubber pad to prevent damage to the cable due to collision when it falls. At the same time, it can collect the processed cable in a concentrated manner for easy subsequent unified sorting.

[0029] In addition, a flexible pad 531 is included. The two clamping blocks 53 in the same clamping seat 5 each have a groove on their opposite side. The flexible pad 531 is installed in the groove by a fixing component. Its material is wear-resistant rubber. When the clamping block 53 clamps the cable, the flexible pad 531 will first contact the cable surface, which can buffer the clamping force of the clamping block 53 and prevent the cable sheath from being pinched or the conductor from being deformed. The surface of the flexible pad 531 has fine texture, which can increase the friction between it and the cable, making it less likely for the cable to slip out of the clamping seat 5 during transmission and improving the stability of the clamping.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
