Description

Technical Field

[0001] This application relates to the field of terminal block processing technology, and in particular to a terminal block bending device. Background Technology

[0002] Terminal blocks are core components in electrical equipment and wiring systems, primarily used to achieve conductive connections between wires and circuit boards, and between wires themselves. They are widely used in industrial control equipment, automotive electronics, smart homes, power communications, and many other fields. To adapt to different assembly spaces, wiring structures, and soldering requirements, terminal blocks need to be bent using bending equipment to meet assembly and usage requirements.

[0003] Currently, existing terminal block bending equipment typically involves loading multiple terminals in rows onto a processing base, then conveying the base to a bending mechanism. The bending mechanism then bends the rows of terminals on the base, and finally unloads the bent terminals from the base before loading the next batch. This process of loading and unloading the terminals to the base consumes a significant portion of the processing time, directly impacting bending efficiency. Therefore, reducing the loading and unloading time to improve bending efficiency is a pressing issue that needs to be addressed in terminal block bending. Summary of the Invention

[0004] To improve the efficiency of terminal block bending, this application provides a terminal block bending device.

[0005] The terminal bending device provided in this application adopts the following technical solution: A terminal bending device includes a frame, a guide rail, a processing seat, a lifting seat, a conveying mechanism, a bending mechanism, and a lifting mechanism. The guide rail is mounted on the frame. Multiple processing seats are slidably mounted on the guide rail. The lifting seats are vertically slidably mounted on the processing seats. Both the processing seats and the lifting seats have multiple positioning holes arranged in rows along the length of the guide rail for inserting terminal blocks. The conveying mechanism is mounted on the frame and is used to drive the processing seats to slide along the guide rail. The bending mechanism is mounted on the frame and is used to bend the terminal blocks on the processing seats or the lifting seats. The lifting mechanism is mounted on the frame and is used to lift the lifting seats on the processing seats.

[0006] By adopting the above technical solution, workers feed multiple terminals to be bent into multiple positioning holes on the processing base and the lifting base. The conveying mechanism drives the processing base to slide along the guide rail. After the processing base moves to the guide rail where the bending mechanism is located, the bending mechanism first bends the multiple terminals in rows on the processing base. Then, the lifting mechanism drives the lifting base on the processing base to rise, and the bending mechanism then bends the multiple terminals in rows on the lifting base. Finally, the conveying mechanism transports the processing base along the guide rail to unload the terminals. This allows the bending of two rows of terminals to be completed in one operation, increasing the number of terminals that can be bent in one transport operation, reducing the frequency of loading and unloading terminals, and thus reducing the loading and unloading time of terminals, effectively improving the efficiency of terminal bending.

[0007] Optionally, the conveying mechanism includes a pusher and a positioning member. The pusher is mounted on the frame and is used to drive the processing seat at the feed end of the guide rail to slide toward the discharge end of the guide rail. The positioning member is mounted on the frame and is used to position the processing seat at the processing position.

[0008] By adopting the above technical solution, multiple processing seats are arranged sequentially on the guide rail along its length. The pusher drives the processing seat at the feed end of the guide rail to slide towards the discharge end of the guide rail. Multiple processing seats abut against each other in sequence, so that multiple processing seats can move synchronously along the guide rail. In addition, the positioning component can also position the processing seat at the bending mechanism position, improve the stability of the processing seat at the bending mechanism position, and facilitate the subsequent bending mechanism to perform accurate bending processing on the terminal block.

[0009] Optionally, the bending mechanism includes a bending seat, a first driving member, a bending roller, and a second driving member. The bending seat is slidably mounted on the frame toward the guide rail. The first driving member is mounted on the frame and is used to drive the bending seat to slide. The bending roller is slidably mounted on the frame toward the bending seat. The second driving member is mounted on the frame and is used to drive the bending roller to slide.

[0010] By adopting the above technical solution, the first driving member drives the bending seat to slide towards the guide rail, and the bending seat abuts against the bending point of multiple terminals in a row on the processing seat or lifting seat. Then, the second driving member drives the bending roller to move towards the bending seat, and the bending roller abuts against the multiple terminals in a row on the processing seat or lifting seat, bending the multiple terminals in a row on the processing seat or lifting seat from the abutment point of the bending seat. During the bending process, the bending roller can rotate, reducing the possibility of damaging the terminals.

[0011] Optionally, the lifting mechanism includes a top block and a third driving member. The top block is vertically slidably mounted on the frame, and the third driving member is mounted on the frame and used to drive the top block to slide. The bottom of the processing seat has a lifting hole for the top block to pass through.

[0012] By adopting the above technical solution, after the machining seat moves above the top block, the third driving component drives the top block to move upward, and the top block can move upward from the lifting hole opened at the bottom of the machining seat to abut against the lifting seat, thus conveniently driving the lifting seat on the machining seat to move upward.

[0013] Optionally, the frame is provided with a leveling mechanism for leveling multiple terminals on the processing seat or lifting seat to the same height. The leveling mechanism includes a first leveling seat, a second leveling seat, a locking member, and a fourth driving member. The first leveling seat is vertically slidably mounted on the frame and is used to abut against multiple terminals on the processing seat. The second leveling seat is vertically slidably mounted on the first leveling seat and is used to abut against multiple terminals on the lifting seat. The locking member is mounted on the first leveling seat and is used to position the second leveling seat. The fourth driving member is mounted on the frame and is used to drive the first leveling seat to move up and down.

[0014] By adopting the above technical solution, before the processing seat is conveyed along the guide rail to the bending mechanism for bending, the second leveling seat is first moved vertically relative to the first leveling seat, so that the height difference between the second leveling seat and the first leveling seat is adjusted to the height difference between the terminals on the processing seat and the terminals on the lifting seat. Then, the second leveling seat is positioned by the locking component. When the processing seat moves below the first leveling seat, the fourth driving component drives the first leveling seat to descend, and the first leveling seat drives the second leveling seat to descend. The first leveling seat can then abut against the top of the multiple terminals on the processing seat, and the second leveling seat abuts against the top of the multiple terminals on the lifting seat. This ensures that the tops of the multiple terminals on the processing seat and the multiple terminals on the lifting seat are at the same height, which facilitates the subsequent bending of the multiple terminals on the processing seat or the lifting seat at the same height position, thus improving the bending quality of the terminals.

[0015] Optionally, both the processing seat and the lifting seat are provided with a support mechanism for supporting the terminals in the positioning hole. The support mechanism includes a support block, a control sleeve, a return spring, a brake rubber strip, a support spring, and a control component. The support block is slidably disposed on the inner wall of the positioning hole along the opening direction of the positioning hole. The control sleeve is vertically slidably disposed on the side of the support block away from the bottom wall of the positioning hole. The return spring is disposed on the support block and connected to the control sleeve. The brake rubber strip is slidably disposed on the support block along the radial direction of the support block. The support spring is disposed on the bottom wall of the positioning hole and connected to the support block. The frictional force between the brake rubber strip and the side wall of the positioning hole is greater than the force exerted by the support spring to drive the support block to move away from the bottom wall of the positioning hole. The control component is disposed on the support block and is used to drive the brake rubber strip to slide when the control sleeve moves toward the bottom wall of the positioning hole.

[0016] By adopting the above technical solution, when the terminal block is fed into the positioning hole on the processing seat or lifting seat, the support spring supports the support block, and the bottom of the terminal block abuts against the control sleeve. Subsequently, when the first leveling seat and the second leveling seat descend and press the top of the terminal block, the terminal block presses down on the control sleeve, and the control sleeve moves down toward the bottom wall of the positioning hole. At the same time, the support block moves down, and the control component drives the brake rubber strip to gradually slide out radially from the support block. After the first leveling seat or the second leveling seat presses the terminal block down to the set height, the brake rubber strip can abut against the side wall of the positioning hole, thereby positioning the support block. Subsequently, after the first leveling seat and the second leveling seat move up, the terminal block is maintained at the current height, so that the top of the terminal block of different lengths can be adjusted to the same height position, improving the applicability of top leveling of terminal blocks of different lengths.

[0017] Optionally, the control assembly includes a rotating sleeve, a slider, a cam, and a connecting rod. The rotating sleeve is rotatably mounted on the support block and located inside the control sleeve. Multiple sequentially connected guide grooves are inclinedly formed on the outer wall of the rotating sleeve. The slider is mounted on the control sleeve and slides within the guide grooves. The guide grooves are used to drive the rotating sleeve to rotate under the abutment of the slider when the control sleeve moves toward the bottom wall near the positioning hole. The cam is coaxially mounted on the rotating sleeve, and multiple control grooves are eccentrically formed on the cam. The multiple control grooves are sequentially connected circumferentially. The connecting rod is hinged to the brake rubber strip and slides on the control grooves. The control grooves are used to drive the connecting rod to extend or retract the brake rubber strip from the support block when the rotating sleeve rotates.

[0018] By adopting the above technical solution, the terminal pressing control sleeve moves downward, the control sleeve drives the slider to move, the slider presses against the side wall of the guide groove, which causes the rotating sleeve to rotate. The rotating sleeve drives the cam to rotate, and the side wall of the eccentrically opened control groove on the cam presses against the connecting rod. The connecting rod then drives the brake rubber strip to extend out of the support block. After the downward pressure of the first leveling seat or the second leveling seat on the terminal is canceled, the return spring drives the control sleeve to move upward and reset. When the bent terminal is subsequently removed from the positioning hole, the bent terminal is first moved downward, causing the control sleeve to move downward again. The control sleeve drives the slider to move again, and the slider presses against the side wall of the guide groove again, causing the rotating sleeve to drive the cam to continue moving. The side wall of the eccentrically opened control groove on the cam, which is closer to the axis of the cam, pulls the connecting rod closer to the axis of the cam. The connecting rod then pulls the brake rubber strip back into the support block. The support spring drives the support block to reset, making it convenient to load the terminal to be bent into the positioning hole and level it in the next operation.

[0019] Optionally, the control slot includes an ejection section and a retraction section, the ejection section and the retraction section are connected, and the retraction section is connected to the ejection section of an adjacent control slot. The ejection section is used to drive the connecting rod to extend the brake rubber strip out of the outer wall of the support block when the rotating sleeve rotates by the angle of the guide slot. The retraction section is used to drive the connecting rod to retract the brake rubber strip into the support block when the rotating sleeve rotates by the angle of the guide slot.

[0020] By adopting the above technical solution, when the control sleeve moves down once and the rotating sleeve rotates by the angle of a guide groove, the pop-out segment drive linkage drives the brake rubber strip to extend out of the outer wall of the support block. When the control sleeve moves down once again and the rotating sleeve rotates by the angle of another guide groove, the retraction segment drive linkage drives the brake rubber strip back into the support block. This allows for convenient control of the brake rubber strip and continuous control of the reciprocating movement of the brake rubber strip by continuously driving the cam to rotate.

[0021] Optionally, the frame is provided with a loading / unloading mechanism for loading the processing seat onto the guide rail. The loading / unloading mechanism includes a unloading component, a transfer component, and a loading component. The unloading component is mounted on the frame and is used to unload the bent terminal block from the outlet end of the guide rail. The unloading component includes a rotating seat, a rotating component, an unloading seat, an extension component, grippers, and a lifting component. The rotating seat is rotatably mounted on the frame. The rotating component is mounted on the frame and is used to drive the rotating seat to rotate. The unloading seat is horizontally slidably mounted on the rotating seat. The extension component is mounted on the rotating seat and is used to drive the unloading seat to slide. At least two grippers are vertically slidably mounted on the unloading seat. The grippers are used to clamp the terminal block on the processing seat or lifting seat. The lifting component is mounted on the unloading seat and is used to drive the grippers to slide. The transfer component is mounted on the frame and is used to transfer the processing seat from the outlet end of the guide rail to the inlet end. The loading component is mounted on the frame and is used to load the terminal block to be bent into the positioning hole.

[0022] By adopting the above technical solution, after the processing seat moves multiple bent terminals along the guide rail to the discharge end of the guide rail, the rotating component drives the rotating seat to rotate, the rotating seat drives the unloading seat to rotate, and the unloading seat drives two grippers to move to the two rows of bent terminals facing the processing seat and the lifting seat respectively. The extension component drives the unloading seat to move towards the direction closer to the terminals, so that the two grippers can clamp the terminals along the arrangement direction of the rows of bent terminals on the processing seat and the lifting seat. After clamping, the lifting component first moves the grippers... The jaws move downwards, causing the bent terminal to move down. Then, the lifting component moves the jaws upwards, allowing them to pull the bent terminal out of the positioning hole. The rotating component then drives the rotating seat to rotate, and the extension component drives the unloading seat to slide, so that the jaws hold the bent terminal to the unloading position for unloading. Then, the transfer component transfers the unloaded processing seat from the output end of the guide rail to the input end, and the loading component loads the terminal to be bent into the positioning hole, thus facilitating the bending of multiple terminal blocks in the next batch.

[0023] Optionally, the feeding assembly includes a vibratory feeder, an inclined seat, an inclined member, an adjusting seat, an adjusting member, a first receiving tray, a second receiving tray, a first shaping seat, a first shaping member, a second shaping seat, and a second shaping member. The vibratory feeder is mounted on the frame and is used to feed the terminals to be bent. The inclined seat is rotatably mounted on the frame between the processing seat at the feed end of the guide rail and the vibratory feeder. The inclined member is mounted on the frame and is used to drive the inclined seat to rotate. The adjusting seat is slidably mounted on the inclined seat, and the adjusting member is mounted on the inclined seat and is used to drive the adjusting seat to slide. The first receiving tray is... On the adjusting seat, the first receiving tray has a plurality of first receiving grooves arranged on it, corresponding to a plurality of positioning holes on the processing seat. The second receiving tray is arranged on the adjusting seat, and the second receiving tray has a plurality of second receiving grooves arranged on it, corresponding to a plurality of positioning holes on the lifting seat. The first shaping seat is slidably disposed on the adjusting seat toward the first receiving tray. The first shaping component is disposed on the adjusting seat and is used to drive the first shaping seat to slide. The second shaping seat is slidably disposed on the adjusting seat toward the second receiving tray. The second shaping component is disposed on the adjusting seat and is used to drive the second shaping seat to slide.

[0024] By adopting the above technical solution, the vibratory feeder vibrates and feeds the terminals to be bent. The tilting component first rotates the tilting seat to the angle of the vibratory feeder's outlet, aligning the first receiving plate with the outlet. The adjusting component drives the adjusting seat to slide, allowing the terminals fed by the vibratory feeder to be sequentially fed into the multiple first receiving slots on the first receiving plate. Then, the tilting component drives the tilting seat to rotate the second receiving plate to align with the outlet of the vibratory feeder. The adjusting component drives the adjusting seat to slide, allowing the terminals fed by the vibratory feeder to be sequentially fed into the multiple second receiving slots on the second receiving plate. Then, the first shaping component drives the first shaping seat to move towards the first receiving plate, pressing the multiple terminals on the first receiving plate. The second shaping component drives the second shaping seat towards the second receiving plate. The first shaping seat moves to press multiple terminals on the second receiving tray. Then, the tilting component first rotates the tilting seat so that the first receiving tray tilts downward and aligns with the processing seat. The first shaping seat moves away from the first receiving tray, and the multiple terminals on the first receiving tray can slide into the multiple positioning holes on the processing seat. The tilting component then drives the tilting seat to rotate so that the second receiving tray tilts downward and aligns with the lifting seat. The second shaping seat moves away from the second receiving tray, and the multiple terminals on the second receiving tray can slide into the multiple positioning holes on the lifting seat. This improves the feeding efficiency of the terminals and can shape the terminals fed by the vibratory feeder, improve the straightness of the terminals, facilitate the smooth insertion of the terminals into the positioning holes, and enable more accurate bending processing of the terminals in the future.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The bending process of two rows of terminals can be completed in one go, which increases the number of terminals that can be bent in one feeding of the processing base, reduces the frequency of loading and unloading terminals, and thus reduces the loading and unloading time of terminals, effectively improving the efficiency of terminal bending process; 2. The control component drives the brake rubber strip to gradually slide out radially from the support block, so that after the first or second leveling seat presses the terminal down to the set height, the brake rubber strip can press against the side wall of the positioning hole, thereby positioning the support block. After the first and second leveling seats move up, the terminal remains at the current height, so that the top of the terminal of different lengths can be adjusted to the same height position, improving the applicability of the top leveling of terminal of different lengths. 3. Improves the feeding efficiency of terminal blocks and can shape the terminal blocks fed by the vibratory feeder, improve the straightness of the terminal blocks, so that the terminal blocks can be smoothly inserted into the positioning holes and the terminal blocks can be bent more accurately in the subsequent process.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0037] Example 1: This application discloses a terminal bending device.

[0038] Reference Figure 1 , Figure 2 The terminal bending equipment includes a frame 1, a guide rail 2, a processing seat 3, a lifting seat 4, a conveying mechanism 5, a bending mechanism 6, a lifting mechanism 7, and a leveling mechanism 9.

[0039] Reference Figure 2 , Figure 3 The guide rail 2 is mounted on the frame 1. Multiple processing seats 3 are slidably mounted on the guide rail 2. The multiple processing seats 3 are arranged in sequence along the length of the guide rail 2. In this embodiment, the guide rail 2 includes two guide rods spaced apart on the frame 1. The processing seats 3 slide between the two guide rods. The lifting seat 4 is vertically slidably mounted on the processing seat 3. Both the processing seat 3 and the lifting seat 4 are provided with multiple positioning holes 8 for inserting terminals. The multiple positioning holes 8 are arranged in rows along the length of the guide rail 2 on both the processing seat 3 and the lifting seat 4. The multiple positioning holes 8 arranged in rows on the processing seat 3 and the multiple positioning holes 8 arranged in rows on the lifting seat 4 are parallel to each other in the length of the guide rail 2.

[0040] Reference Figure 2 , Figure 4 The lifting mechanism 7 is mounted on the frame 1. The lifting mechanism 7 is used to lift the lifting seat 4 on the processing seat 3. The lifting mechanism 7 includes a top block 71 and a third driving member. One top block 71 is vertically slidably mounted on the frame 1 at each terminal processing point. The top block 71 is located between two guide rods of the guide rail 2. The processing seat 3 has a lifting hole at the bottom of the vertical sliding path of the lifting seat 4 for the top block 71 to pass through. The third driving member is mounted on the frame 1. The third driving member is used to drive the top block 71 to slide. In this embodiment, the third driving member is a cylinder. The cylinder is vertically mounted on the frame 1, and the piston rod of the cylinder is connected to the top block 71.

[0041] When the processing base 3 moves the lifting base 4 to the processing position of the terminal block, the top block 71 is located below the processing base 3 and is directly opposite the lifting hole. The third driving member drives the top block 71 to move upward, so that the top block 71 can move upward from the lifting hole opened at the bottom of the processing base 3. Then the top block 71 abuts against the bottom of the lifting base 4. As the top block 71 continues to rise, the lifting base 4 can be easily lifted on the processing base 3, thereby realizing the bending of the terminal block on the processing base 3 and the bending of the terminal block on the lifting base 4.

[0042] Reference Figure 2 , Figure 4The conveying mechanism 5 is mounted on the frame 1. The conveying mechanism 5 drives the processing seat 3 to slide along the guide rail 2. The conveying mechanism 5 includes a pusher 51 and a positioning member 52. The pusher 51 is mounted on the frame 1 and drives the processing seat 3 at the feed end of the guide rail 2 to slide towards the discharge end of the guide rail 2. The pusher 51 can be a linearly driven component such as a cylinder or electric actuator. In this embodiment, the pusher 51 is a cylinder, mounted on the frame 1 at the feed end of the guide rail 2. The extension and retraction direction of the cylinder's piston rod is consistent with the length direction of the guide rail 2. When the piston rod extends, it pushes the processing seat 3 at the feed end of the guide rail 2 towards the discharge end of the guide rail 2. Multiple processing seats 3 abut against each other sequentially, allowing them to move synchronously along the guide rail 2. Multiple positioning members 52 are mounted on the frame 1. Multiple positioning components 52 are used to position the processing base 3 at different processing positions of the terminal block. In this embodiment, the positioning component 52 includes a positioning wedge and a cylinder. The positioning wedge is vertically slidably mounted on the frame 1 in the middle of the guide rail 2. The cross-sectional size of the positioning wedge gradually increases from the direction of approaching to away from the processing base 3. The cylinder is mounted on the frame 1, and the piston rod of the cylinder is connected to the positioning wedge. A positioning groove with a diameter that gradually decreases from the direction of approaching to away from the positioning wedge is opened on the bottom of the processing base 3. The cylinder drives the piston rod of the positioning wedge to extend, so that the positioning wedge is close to the bottom of the processing base 3. The positioning wedge can then be inserted into the positioning groove, thereby positioning the processing base 3 at the set processing position, improving the stability of the processing base 3 at the processing position, and facilitating accurate bending processing of the terminal block in the subsequent process.

[0043] Reference Figure 2 , Figure 3 A leveling mechanism 9 is mounted on the frame 1. The leveling mechanism 9 is used to level multiple terminals arranged in a row on the processing seat 3 or the lifting seat 4 to the same height. The leveling mechanism 9 includes a first leveling seat 91, a second leveling seat 92, a locking member 93, and a fourth driving member 94. The first leveling seat 91 is vertically slidably mounted on the frame 1 above the guide rail 2. The first leveling seat 91 is used to abut against the top of multiple terminals on the processing seat 3. The second leveling seat 92 is vertically slidably mounted on the first leveling seat 91. The locking member 93 is mounted on the first leveling seat 91. The locking member 93 is used to position the second leveling seat 92 on the first leveling seat 91. In this embodiment, the locking member 93 is a screw, which is rotatably mounted on the first leveling seat 91 and threaded through the second leveling seat 92. The fourth driving member 94 is mounted on the frame 1 and is used to drive the first leveling seat 91 to move up and down.

[0044] Based on the height difference between the top of the terminals on the lifting seat 4 and the top of the terminals on the processing seat 3 when the lifting seat 4 is not lifted, the operator drives the second leveling seat 92 to slide vertically on the first leveling seat 91. This adjusts the height difference between the bottom of the second leveling seat 92 and the bottom of the first leveling seat 91 to match the height difference between the terminals on the processing seat 3 and the lifting seat 4. After the processing seat 3 moves along the guide rail 2 to below the first leveling seat 91, the fourth driving component 94 drives the first leveling seat 91 to descend. The first leveling seat 91 then drives the second leveling seat 92 to descend, allowing the first leveling seat 91 to abut against the... The tops of multiple terminals on the processing base 3, and the tops of multiple terminals on the lifting base 4, are simultaneously abutted by the second leveling base 92, so that the terminals on both the processing base 3 and the lifting base 4 are inserted to the set depth of the positioning hole 8, and the tops of the multiple terminals on the processing base 3 and the lifting base 4 are kept at the same height. This facilitates the subsequent bending of the multiple terminals on the processing base 3 or the lifting base 4 at the same height, reduces the accuracy requirement for the insertion depth when loading the terminals into the positioning hole 8, and improves the bending quality of the terminals.

[0045] Reference Figure 2 , Figure 4The bending mechanism 6 is mounted on the frame 1. The bending mechanism 6 is used to bend the terminals on the processing seat 3 or the lifting seat 4. The bending mechanism 6 includes a bending seat 61, a first driving member 62, a bending roller 63, and a second driving member 64. The bending seat 61 is slidably mounted on the frame 1 on one side of the guide rail 2 in a direction perpendicular to the guide rail 2. In this embodiment, the bending seat 61 is a wedge-shaped configuration with its cross-sectional dimensions gradually decreasing from near the guide rail 2 to far away from the guide rail 2. The bottom of the bending seat 61 has a groove for the bent terminals on the processing seat 3 to be inserted into, allowing the terminals to be bent more downwards, reducing the possibility of the bent portion of the terminal recovering its deformation after bending and resulting in an unqualified bending angle. Furthermore, when the bending contact is made with the terminals on the lifting seat 4, the side wall of the groove on the bending seat 61 can continue to compress and bend the terminals. The wire terminal enhances the bending effect of the terminal on the processing seat 3, and allows the bent terminal on the processing seat 3 to enter the groove at the bottom of the bending seat 61, so that the bending seat 61 can smoothly abut against the terminal on the lifting seat 4; the first driving member 62 is mounted on the frame 1 and is used to drive the bending seat 61 to slide. In this embodiment, the first driving member 62 is a cylinder; the bending roller 63 is slidably mounted on the frame 1 on the other side of the guide rail 2 toward the bending seat 61; the second driving member 64 is mounted on the frame 1 and is used to drive the bending roller 63 to slide toward the bending seat 61. In this embodiment, the bending roller 63 includes a bending frame and a roller. The bending frame is slidably mounted on the frame 1, and the bending roller 63 is rotatably mounted on one end of the bending frame near the bending seat 61. The second driving member 64 is a cylinder that drives the bending frame to slide the bending roller 63.

[0046] The first driving member 62 drives the bending seat 61 to move towards the guide rail 2. The bending seat 61 first abuts against the bending point of the multiple terminals in a row on the processing base 3. Then, the second driving member 64 drives the bending roller 63 to approach the bending seat 61. The bending roller 63 can then drive the multiple terminals in a row to bend from the abutment point of the bending seat 61 towards the bending seat 61 through the abutment action. During the bending process, the roller of the bending roller 63 can rotate and roll and rub against the terminals. This reduces the possibility of damaging the terminals; then the first drive member 62 drives the bending seat 61 away from the guide rail 2, and the second drive member 64 drives the bending roller 63 away from the bending seat 61. After the lifting seat 4 is lifted, the first drive member 62 drives the bending seat 61 to abut against the row of terminals on the lifting seat 4, and the second drive member 64 drives the bending roller 63 to abut against the row of terminals on the lifting seat 4 again for bending, thereby conveniently completing the bending of multiple terminals in rows on the processing seat 3 and the lifting seat 4.

[0047] The implementation principle of Embodiment 1 of this application is as follows: The operator inserts multiple terminals to be bent into the multiple positioning holes 8 on the processing seat 3 and the lifting seat 4 respectively. Then, the processing seat 3 is loaded onto the guide rail 2. The conveying mechanism 5 drives the processing seat 3 to move along the guide rail 2. The leveling mechanism 9 first levels the tops of the multiple terminals in rows on the processing seat 3 and the multiple terminals in rows on the lifting seat 4 to the same height. Then, the processing seat 3 continues to move to the bending mechanism 6. The bending mechanism 6 first bends the row of terminals with higher height on the processing seat 3. Then, the lifting mechanism 7 lifts the lifting seat 4 on the processing seat 3 and raises it. The bending mechanism 6 then bends the row of terminals on the lifting seat 4. Then, the conveying mechanism 5 continues to drive the processing seat 3 to move along the guide rail 2 to unload the terminals. This realizes the bending processing of two rows of terminals in one operation. The number of terminals bent in one conveying operation of the lifting processing seat 3 is reduced, the frequency of loading and unloading terminals is reduced, and the loading and unloading time of terminals is reduced, effectively improving the efficiency of terminal bending processing.

[0048] Example 2, the difference between this example and Example 1 is as follows: Reference Figure 5 The frame 1 is equipped with a loading and unloading mechanism 11, which is used to load the processing seat 3 onto the guide rail 2. The loading and unloading mechanism 11 includes a unloading component 111, a transfer component 112 and a loading component 113.

[0049] Reference Figure 5 , Figure 6The unloading assembly 111 is mounted on the frame 1. The unloading assembly 111 is used to unload the bent terminal blocks from the outlet end of the guide rail 2. The unloading assembly 111 includes a rotating base 1111, a rotating component 1112, an unloading base 1113, an extension component 1114, a gripper 1115, and a lifting component 1116. The rotating base 1111 is rotatably mounted on the frame 1 at the outlet end of the guide rail 2. The rotating component 1112 is mounted on the frame 1 and is used to drive the rotating base 1111 to rotate. In this embodiment, the rotating component 1112 is a servo motor, mounted on the frame 1, and its output shaft is coaxially connected to the rotating base 1111. The unloading base 1113 is slidably mounted on the rotating base 1111 in a horizontal direction, and the extension component 1114 is mounted on the rotating base 1111. 1. The extension 1114 is used to drive the unloading seat 1113 to slide. In this embodiment, the extension 1114 is a cylinder. Two grippers 1115 are slidably installed on the unloading seat 1113 in the vertical direction. The two grippers 1115 are horizontally spaced apart. The grippers 1115 are used to clamp the terminals on the processing seat 3 or the lifting seat 4. The lifting member 1116 is installed on the unloading seat 1113. The lifting member 1116 is used to drive the two grippers 1115 to rise and fall. In this embodiment, the lifting member 1116 includes a cylinder. The cylinder is vertically installed on the unloading seat 1113. The grippers 1115 include a double-headed cylinder and two clamping plates. The double-headed cylinder is installed on the piston rod of the cylinder of the lifting member 1116. The two clamping plates are respectively installed on the two piston rods of the double-headed cylinder.

[0050] After the processing seat 3, carrying the bent terminals, is conveyed to the discharge end of the guide rail 2, the rotating component 1112 drives the rotating seat 1111 to rotate. The rotating seat 1111 drives the unloading seat 1113 to rotate. The unloading seat 1113 drives the two grippers 1115 to rotate towards the rows of terminals on the processing seat 3 and the rows of terminals on the lifting seat 4, respectively. After the lifting mechanism 7 lifts the lifting seat 4, the extension component 1114 drives the unloading seat 1113 to move towards the terminals. The unloading seat 1113 can then drive the two grippers 1115 to move, so that the rows of terminals on the processing seat 3... The terminal blocks and the rows of terminals on the lifting seat 4 are located between the two clamping plates of the two grippers 1115. The grippers 1115 can clamp the rows of terminals. Then, the lifting component 1116 drives the grippers 1115 to move upward, and the grippers 1115 can pull the bent terminals out of the positioning hole 8. Then, the rotating component 1112 drives the rotating seat 1111 to rotate, and the extension component 1114 drives the unloading seat 1113 to slide, so that the grippers 1115 clamp the bent terminals to the unloading position and release them for unloading, so that the bent terminals can be easily unloaded from the positioning hole 8.

[0051] Reference Figure 5The transfer assembly 112 is mounted on the frame 1. The transfer assembly 112 is used to transfer the processing seat 3 from the discharge end of the guide rail 2 to the feed end. In this embodiment, the transfer assembly 112 includes a first slide rail, a first lifting cylinder, a second slide rail, a second lifting cylinder, a third slide rail, and a transfer cylinder. The first slide rail slides vertically on the frame 1 at the discharge end of the guide rail 2. The first lifting cylinder is mounted vertically on the frame 1. The piston rod of the first lifting cylinder is connected to the bottom of the first slide rail. The second slide rail slides vertically on the frame 1 at the feed end of the guide rail 2. The second lifting cylinder is mounted vertically on the frame 1. The piston rod of the second lifting cylinder is connected to the bottom of the second slide rail. The third slide rail is mounted on the frame 1 below the guide rail 2. The transfer cylinder is mounted on the frame 1. The piston rod of the transfer cylinder faces the length direction of the third slide rail.

[0052] The first lifting cylinder drives the first slide rail to move upward and connect with the discharge end of the guide rail 2. After the bent terminals on the processing seat 3 and the lifting seat 4 are unloaded, the processing seat 3 enters the first slide rail from the discharge end of the guide rail 2. Then, the first lifting cylinder drives the first slide rail to move downward and connect with the third slide rail. The second lifting cylinder drives the second slide rail to move downward and connect with the third slide rail. The piston rod of the transfer cylinder extends, which pushes the processing seat 3 on the third slide rail into the second slide rail. The piston rod of the second lifting cylinder extends, which raises the second slide rail to connect with the guide rail 2. The pusher 51 can push the processing seat 3 on the second slide rail onto the guide rail 2, which facilitates the transfer of the processing seat 3 from the discharge end to the feed end of the guide rail 2.

[0053] Reference Figure 5 , Figure 7The feeding assembly 113 is mounted on the frame 1. The feeding assembly 113 is used to feed the bent terminal blocks into the positioning holes 8. The feeding assembly 113 includes a vibratory feeder 1131, an inclined seat 1132, an inclined member 1133, an adjusting seat 1134, an adjusting member 1135, a first receiving tray 1136, a second receiving tray 1137, a first shaping seat 1138, a first shaping member 1139, a second shaping seat 1140, and a second shaping member 1141. The vibratory feeder 1131 is mounted on the frame 1 at the feeding end of the guide rail 2. The vibratory feeder 1131 is used to vibrate and feed the terminal blocks to be bent. The inclined seat 1132 is hinged to the vibratory feeder 1131. An inclined member 1133 is mounted on the frame 1 between the discharge port of the vibrating disc 1131 and the second slide rail. The inclined member 1133 is used to drive the inclined seat 1132 to rotate. In this embodiment, the inclined member 1133 is a cylinder, which is mounted on the frame 1. The piston rod of the cylinder is hinged to the inclined seat 1132. The extension and retraction of the piston rod of the cylinder can drive the inclined seat 1132 to rotate. An adjusting seat 1134 is slidably mounted on the inclined seat 1132 in a direction perpendicular to the discharge port of the vibrating disc 1131. An adjusting member 1135 is mounted on the inclined seat 1132 and is used to drive the adjusting seat 1134 to slide. In this example, the adjusting component 1135 is a cylinder; the first receiving plate 1136 is mounted on the adjusting seat 1134, and the first receiving plate 1136 has multiple first receiving grooves along the discharge direction of the vibrating plate 1131. The multiple first receiving grooves are spaced apart along a direction perpendicular to the discharge direction of the vibrating plate 1131, and the interval between adjacent first receiving grooves is the same as the interval between adjacent positioning holes 8 on the processing seat 3. The second receiving plate 1137 is mounted on the adjusting seat 1134, and the second receiving plate 1137 and the first receiving plate 1136 are distributed vertically on the adjusting seat 1134. The second receiving plate 1137 has multiple grooves arranged on it, which are the same as those on the lifting seat 4. The second receiving groove corresponding to each positioning hole 8; the first shaping seat 1138 is slidably mounted on the adjusting seat 1134 toward the first receiving plate 1136; the first shaping component 1139 is mounted on the adjusting seat 1134 and is used to drive the first shaping seat 1138 to slide. In this embodiment, the first shaping component 1139 is a cylinder; the second shaping seat 1140 is slidably mounted on the adjusting seat 1134 toward the second receiving plate 1137; the second shaping component 1141 is mounted on the adjusting seat 1134 and is used to drive the second shaping seat 1140 to slide. In this embodiment, the second shaping component 1141 is a cylinder.

[0054] When the second slide rail drives the empty processing seat 3 and lifting seat 4 to rise to connect with the guide rail 2, the vibratory feeder 1131 vibrates and feeds the terminals to be bent. The tilting member 1133 first causes the tilting seat 1132 to rotate, and the tilting seat 1132 drives the first receiving plate 1136 to rotate to align with the discharge port of the vibratory feeder 1131. The terminals fed from the discharge port of the vibratory feeder 1131 can then be fed into the first receiving groove on the first receiving plate 1136. Then, the adjusting member 1135 drives the adjusting seat 1134 to slide in a direction perpendicular to the discharge port of the vibratory feeder 1131, so that the terminals fed from the vibratory feeder 1131 are sequentially fed into the remaining first receiving grooves on the first receiving plate 1136. Then, the tilting member 1133 drives the adjusting seat 1134 to slide in a direction perpendicular to the discharge port of the vibratory feeder 1131. This allows the terminals fed from the vibratory feeder 1131 to be fed into the remaining first receiving grooves on the first receiving plate 1136 in a sequential manner. Then, the tilting member 1133 drives the adjusting seat 1134 to slide again. The tilting seat 1132 rotates, causing the second receiving tray 1137 to rotate and align with the outlet of the vibrating plate 1131. The terminals fed from the vibrating plate 1131 are then fed into the second receiving slot of the second receiving tray 1137. Then, the adjusting member 1135 drives the adjusting seat 1134 to slide again, allowing the terminals fed from the vibrating plate 1131 to be sequentially fed into the remaining second receiving slots of the second receiving tray 1137. Next, the first shaping member 1139 drives the first shaping seat 1138 closer to the first receiving tray 1136, pressing the multiple terminals on the first receiving tray 1136 together. Finally, the second shaping member 1141 drives the second shaping seat 1140 closer to the second receiving tray 1136. 7. The second shaping seat 1140 presses the multiple terminals on the second receiving tray 1137, thereby shaping the terminals fed by the vibratory feeder 1131 through the squeezing action of the first shaping seat 1138 and the first receiving groove, as well as the squeezing action of the second shaping seat 1140 and the second receiving groove, improving the straightness of the terminals, making it easier for the terminals to be smoothly inserted into the positioning holes 8, and enabling more accurate bending processing of the terminals in the future; after the terminals are fed onto the first receiving tray 1136 and the second receiving tray, the tilting member 1133 drives the coupler to rotate again, causing the tilting seat 1132 to tilt the first receiving tray downward toward the processing seat 3, and the multiple first receiving grooves on the first receiving tray 1136 respectively... With the multiple positioning holes 8 on the processing base 3 aligned, the first shaping component 1139 drives the first shaping base 1138 away from the first receiving tray 1136, allowing the multiple terminals on the first receiving tray 1136 to slide into the multiple positioning holes 8 on the processing base 3 respectively. The tilting component 1133 then drives the tilting base 1132 to rotate so that the second receiving tray 1137 tilts downward and aligns with the lifting base 4. The second shaping component 1141 drives the second shaping base 1140 away from the second receiving tray 1137, allowing the multiple terminals on the second receiving tray 1137 to slide into the multiple positioning holes 8 on the lifting base 4 respectively. This quickly realizes the feeding of terminals into the multiple positioning holes 8 on the processing base 3 and the lifting base 4, effectively improving the feeding efficiency of terminals.

[0055] Reference Figure 8 , Figure 9 Both the processing base 3 and the lifting base 4 are equipped with support mechanisms 10. The support mechanisms 10 support the terminals within the positioning holes 8. Each support mechanism 10 includes a support block 101, a control sleeve 102, a return spring 103, a brake rubber strip 104, a support spring 105, and a control assembly 106. One support block 101 is slidably installed in each positioning hole 8 along the opening direction of the positioning hole 8. The control sleeve 102 is vertically slidably installed on the top of the support block 101, away from the bottom of the positioning hole 8. The return spring 103 is installed on the support block 101. Spring 103 is connected to control sleeve 102. Braking groove is provided on the outer wall of support block 101 along the radial direction of support block 101. Braking rubber strip 104 is slidably installed in the braking groove along the opening direction of the braking groove. Support spring 105 is installed on the bottom wall of positioning hole 8. Support spring 105 is connected to the bottom of support block 101. When brake rubber strip 104 extends out of the outer wall of support block 101 and abuts against the side wall of positioning hole 8, the frictional force is greater than the force of support spring 105 driving support block 101 to move upward away from the bottom wall of positioning hole 8.

[0056] Reference Figure 8 , Figure 9The control component 106 is mounted on the support block 101. The control component 106 is used to drive the brake rubber strip 104 to slide when the control sleeve 102 moves toward the bottom wall near the positioning hole 8. The control component 106 includes a rotating sleeve 1061, a slider 1062, a cam 1063, and a connecting rod 1064. The rotating sleeve 1061 is rotatably mounted on the support block 101. The control sleeve 102 covers the rotating sleeve 1061. Multiple guide grooves 10611 are inclinedly formed on the outer wall of the rotating sleeve 1061. The lowest point of the guide groove 10611 is connected to the highest point of the adjacent guide groove 10611 through a vertically formed groove, thereby allowing the multiple guide grooves 10611 to slide. 0611 are connected in sequence. Slider 1062 is installed on the inner wall of control sleeve 102. Slider 1062 slides within guide groove 10611. When control sleeve 102 moves towards the bottom wall of positioning hole 8, it drives slider 1062 to slide within guide groove 10611, thus pressing against the side wall of guide groove 10611 and causing rotating sleeve 1061 to rotate. When return spring 103 drives control sleeve 102 to move upwards and reset, slider 1062 slides from the lowest point of guide groove 10611 along the vertically opened groove to the highest point of adjacent guide groove 10611. Cam 1063 is coaxially mounted on rotating sleeve 1061. 3. Multiple control slots 10631 are eccentrically formed on the support block 101, and the multiple control slots 10631 are connected circumferentially. One end of the connecting rod 1064 is hinged to the brake rubber strip 104, and the other end of the connecting rod 1064 is equipped with a roller, which is embedded in the control slot 10631, thereby realizing the sliding installation of the connecting rod 1064 in the control slot 10631. In this embodiment, a set of brake rubber strips 104 and connecting rods 1064 are respectively installed on both sides of the support block 101. The control slot 10631 includes a pop-out section 106311 and a retraction section 106312. The pop-out section 106311 and the retraction section 106312 are connected, and the retraction section 106311... 2. The pop-out section 106311 is connected to the adjacent control slot 10631. The distance between the pop-out section 106311 and the axis of the cam 1063 gradually increases along the rotation direction of the cam 1063. This causes the connecting rod 1064 to drive the brake rubber strip 104 to extend out of the outer wall of the support block 101 when the rotating sleeve 1061 rotates by the angle of the guide slot 10611. The distance between the retraction section 106312 and the axis of the cam 1063 gradually decreases along the rotation direction of the cam 1063. This causes the connecting rod 1064 to drive the brake rubber strip 104 to retract into the support block 101 when the rotating sleeve 1061 rotates by the angle of the guide slot 10611.

[0057] When the terminal block is fed into the positioning hole 8 on the processing seat 3 or the lifting seat 4, the support spring 105 supports the support block 101, and the return spring 103 supports the control sleeve 102, so that the control sleeve 102 abuts against the bottom of the terminal block and supports the terminal block. Subsequently, the first leveling seat 91 and the second leveling seat 92 press down on the top of the terminal block to level it. Under the pressure, the terminal block moves downward, and the terminal block presses down on the control sleeve 102, so that the control sleeve 102 moves downward toward the bottom wall of the positioning hole 8. The coaxial control sleeve 102 drives the support block 101 to move downward, so that the terminal block can move downward under the pressure. As the control sleeve 102 moves downwards at the set height, it drives the slider 1062 to move. The slider 1062 slides along the inclined guide groove 10611 and presses against the side wall of the guide groove 10611, causing the rotating sleeve 1061 to rotate. The rotating sleeve 1061 then drives the cam 1063 to rotate. The pop-out section 106311 of the control groove 10631 on the cam 1063 first presses against the connecting rod 1064, causing the connecting rod 1064 to move away from the axis of the cam 1063. The connecting rod 1064 then drives the brake rubber strip 104 to extend radially out of the outer wall of the support block 101. When the brake rubber strip 104 presses against the side wall of the positioning hole 8, the support block 101 is positioned at the current height, thereby supporting the terminal block at the current height. This allows the top of the terminal block of different lengths to be adjusted to the same height when it is in the positioning hole 8, improving the applicability of leveling the top of terminal blocks of different lengths. When the gripper 1115 clamps the bent terminal block for unloading, after the gripper 1115 clamps the bent terminal block, the lifting component 1116 first moves the gripper 1115 downward, and then drives the gripper 1115 upward to pull the bent terminal block out of the positioning hole 8. The gripper 1115 can then drive the terminal block... The control sleeve 102 is pressed down again, causing it to move downwards again. The control sleeve 102 then moves the slider 1062, which in turn presses against the side wall of the guide groove 10611. This causes the rotating sleeve 1061 to drive the cam 1063 to continue rotating. The side wall of the retraction section 106312 of the control groove 10631 on the cam 1063 pulls the connecting rod 1064, which in turn drives the brake rubber strip 104 to retract into the support block 101. The support spring 105 drives the support block 101 to reset, and the reset spring 103 drives the control sleeve 102 to move upwards to reset, making it easier to load the terminal block to be bent into the positioning hole 8 and level it in the next operation.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
