Description

Technical Field

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

[0002] Terminals, as fundamental components used to achieve conductive connections in electrical equipment, are widely used in various electrical components such as connectors, relays, and switches. To meet the assembly and connection requirements of different products, some terminals need to be bent and shaped before assembly to form the corresponding spatial shape. The shaped terminals are then inserted into the corresponding housings to complete the terminal assembly.

[0003] In the terminal processing, bending and insertion involve multiple continuous processing steps. In some existing processing methods, terminal bending and insertion are completed by different equipment or workstations. After bending, the terminals need to be transferred to the subsequent insertion workstation, increasing the transfer, positioning, and clamping steps between processes, making the processing flow more complex, and limiting the continuous connection between processes. When processing multiple terminals continuously, the above methods may also affect the continuity of terminal processing, processing efficiency, and the consistency of processing different terminals.

[0004] Furthermore, for terminals requiring two bends, the positioning of the terminals at different bending stations affects the subsequent bending process. If the terminal to be bent shifts position during the bending process, differences in the bending position or shape of different terminals can easily occur, which is not conducive to consistently forming a terminal shape that meets the requirements for subsequent insertion. Therefore, how to stably position the terminals at different bending stations and maintain good consistency between the two bending processes is also an issue that needs to be considered during terminal processing.

[0005] Meanwhile, multiple terminals can typically be connected sequentially to form a terminal strip for processing. When the bent insertion terminal needs to be separated from the terminal strip and further inserted into the housing, the insertion terminal will change from a constrained state connected to the terminal strip to an independent state. If the connection between the terminal separation, holding, and subsequent insertion actions is insufficient, it will be detrimental to maintaining a stable and controlled state of the insertion terminal during the separation and insertion process, thus affecting the smooth progress of subsequent insertion actions. Summary of the Invention

[0006] This invention provides a terminal bending and insertion device to improve the continuity between the terminal bending and insertion processes, and to improve the stability during the terminal bending process and the controllability during the insertion process after cutting off, thereby partially solving or alleviating the above-mentioned deficiencies in the prior art.

[0016] Preferably, the pressing plate and the push plate are respectively provided with L-shaped limiting plates, and the L-shaped limiting plates form limiting spaces with the corresponding pressing plate or the push plate. The first swing rod and the second swing rod are respectively movablely engaged with the corresponding limiting spaces to drive the pressing plate and the push plate to reciprocate toward or away from the insertion terminal. When the pressing plate and the push plate reciprocate along the insertion direction with the mounting frame, the first swing rod and the second swing rod are respectively movablely engaged with the corresponding limiting spaces.

[0017] Preferably, the first cam, the second cam, and the third cam are all provided with guide grooves. The transmission rod is movably engaged with the guide groove of the first cam, the two first rocker arms are movably engaged with the guide groove of the second cam, and the two second rocker arms are movably engaged with the guide groove of the third cam. The first cam, the second cam, and the third cam rotate synchronously with the rotating shaft, and each of the guide grooves has a different trajectory shape, so that the mounting bracket, the two pressing plates, and the two push plates operate in a predetermined sequence.

[0018] Preferably, the device further includes a cutting device disposed between the second bending device and the mating device. The cutting device includes a third frame, a swing arm rotatably disposed on the third frame, and two connecting rods respectively disposed at both ends of the swing arm. One connecting rod connects the third electric cylinder to the swing arm, and the other connecting rod connects the swing arm to the first cutter. The first cutter is movably disposed on the third frame. The third electric cylinder is used to drive the first cutter to cut off the designated terminal in the terminal strip after it has been bent by the second bending device through the two connecting rods and the swing arm.

[0019] Preferably, the conveying device includes a fourth servo motor, a feeding wheel, a first limiting wheel, and a second limiting wheel. The feeding wheel is connected to the output shaft of the fourth servo motor. The outer circumference of the feeding wheel is provided with a plurality of feeding teeth, which are adapted to the positioning holes on the terminal strip. The first limiting wheel and the second limiting wheel have the same structure as the feeding wheel, and the centers of the feeding wheel, the first limiting wheel, and the second limiting wheel are located on the same horizontal straight line along the feeding direction of the terminal strip.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention, by sequentially arranging a first bending device, a second bending device, and an insertion device along the feeding direction of the terminal strip, enables the terminal to sequentially complete the first bending, the second bending, and insertion into the housing. The bending and subsequent insertion of the terminal are integrated into the same device, which helps to simplify the processing flow and improve the continuity and efficiency of terminal processing.

[0022] 2. The present invention positions the terminals to be bent at the corresponding processing stations using the first positioning component and the second positioning component, and performs two bends in opposite directions using the first bending component and the second bending component, so that the terminals are formed into a bending shape that meets the subsequent insertion requirements. At the same time, it helps to reduce the possibility of terminal positional displacement during the bending process and improves the stability of the bending process and the consistency of the bending shape.

[0023] 3. Before the insertion terminal is cut off from the terminal strip, the rear part of the insertion terminal is pressed by the pressing assembly; after the insertion terminal is cut off, the front part is clamped by the clamping insertion assembly, and the pressing of the rear part is released after the clamping is completed, so that the insertion terminal remains under control during the process of changing from the terminal strip connected state to the independent insertion state, which is conducive to the stable completion of subsequent insertion actions.

[0024] 4. This invention uses a terminal strip formed by connecting multiple terminals in sequence as the processing object, so that the terminals can pass through each processing station in sequence along the feeding direction to complete bending and insertion. This helps to reduce intermediate transfers and re-clamping between different processing steps and improves the continuity and consistency of batch processing of terminals.

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] Example

[0040] See Figures 1 to 11 As shown, the present invention provides a terminal bending and insertion device, including a first bending device 1, a second bending device 2, and an insertion device 4 arranged sequentially along the feeding direction of the terminal strip. The terminal strip is a continuous strip formed by connecting multiple terminals sequentially. The terminal strip has multiple positioning holes arranged along the feeding direction. A section of the terminal strip along its length is accommodated in a terminal feeding guide 101 and can move along the extension direction of the terminal feeding guide 101, so that the terminal strip is bent twice by passing through the first bending device 1 and the second bending device 2, and the insertion terminal 201 to be inserted enters the insertion device 4 to complete the bending of the terminal and insertion into the housing 102.

[0041] Specifically, the first bending device 1 includes a first positioning component and a first bending component. When the terminal to be bent moves to the corresponding processing station of the first bending device 1, the first positioning component positions the terminal to be bent, ensuring its stable position during the first bending process. The first positioning component includes a first electric cylinder 12 and a first pressing plate. The first electric cylinder 12 is mounted on the first frame 11 and connected to the first pressing plate. The first electric cylinder 12 can drive the first pressing plate to move towards the terminal strip, so that the first pressing plate presses the terminal to be bent. The first pressing plate is provided with positioning pins that mate with positioning holes on the terminal strip. When the first pressing plate presses the terminal to be bent, the positioning pins extend into the corresponding positioning holes on the terminal strip, thereby positioning the terminal to be bent.

[0042] The first bending assembly is used to perform the first bend on the terminal to be bent after it has been positioned by the first positioning assembly. The first bending assembly includes a first frame 11, a first roller 13, a first bending plate 14, and a first rotary drive assembly. The first roller 13 is rotatably mounted on the first frame 11, and the first bending plate 14 is mounted on the first roller 13. The first rotary drive assembly is connected to the first roller 13 and is used to drive the first roller 13 to rotate the first bending plate 14 around the first bending center, so that the first bending plate 14 acts on the terminal to be bent, thereby forming the first bend at the corresponding position of the terminal to be bent.

[0043] Furthermore, the first rotary drive assembly includes a first grooved wheel 15, a second grooved wheel 16, a first transmission belt 17, and a first servo motor 18. The first grooved wheel 15 is connected to the first roller frame 13. The first servo motor 18 is mounted on the first frame 11. The second grooved wheel 16 is connected to the first servo motor 18. The first transmission belt 17 connects the first grooved wheel 15 and the second grooved wheel 16. The first servo motor 18 drives the second grooved wheel 16 to rotate, and through the first transmission belt 17 drives the first grooved wheel 15 to rotate, thereby driving the first roller frame 13 and the first bending plate 14 to rotate around the first bending center to complete the first bending.

[0044] After the first bend, the terminal strip continues to move along the feeding direction, allowing the terminal to be bent after the first bend to enter the corresponding processing station of the second bending equipment 2. The second bending equipment 2 includes a second positioning component and a second bending component. The second positioning component is used to position the terminal to be bent entering the second bending equipment 2. The second positioning component includes a second electric cylinder 22 and a second pressing plate. The second electric cylinder 22 is disposed on the second frame 21 and connected to the second pressing plate. The second electric cylinder 22 can drive the second pressing plate to move toward the terminal strip, so that the second pressing plate presses the terminal to be bent. The second pressing plate is provided with positioning pins that cooperate with the positioning holes on the terminal strip. When the second pressing plate presses the terminal to be bent, the positioning pins extend into the corresponding positioning holes of the terminal strip, thereby positioning the terminal to be bent.

[0045] The second bending assembly includes a second frame 21, a second roller 23, a second bending plate 24, and a second rotary drive assembly. The second roller 23 is rotatably mounted on the second frame 21, and the second bending plate 24 is mounted on the second roller 23. The second rotary drive assembly is connected to the second roller 23 for driving the second roller 23 to rotate the second bending plate 24 around the second bending center, so as to perform a second bending on the terminal to be bent after the first bending.

[0046] Furthermore, the second rotary drive assembly includes a third grooved wheel 25, a fourth grooved wheel 26, a second transmission belt 27, and a second servo motor 28. The third grooved wheel 25 is connected to the second roller frame 23. The second servo motor 28 is mounted on the second frame 21. The fourth grooved wheel 26 is connected to the second servo motor 28. The second transmission belt 27 connects the third grooved wheel 25 and the fourth grooved wheel 26. The second servo motor 28 drives the fourth grooved wheel 26 to rotate, and through the second transmission belt 27, drives the third grooved wheel 25 to rotate, thereby driving the second roller frame 23 and the second bending plate 24 to rotate around the second bending center to complete the second bending.

[0047] The first bending assembly and the second bending assembly bend the terminal in opposite directions, and the first bending position and the second bending position are spaced apart along the length of the terminal to be bent at the bending front edge, so that the terminal to be bent forms a first bending part and a second bending part that bend in opposite directions after being bent twice, and a connecting section is formed between the first bending part and the second bending part, thereby forming a bending shape that meets the subsequent insertion requirements of the terminal.

[0048] It should be noted that the first and second positioning components are used to position the terminals to be bent at their respective processing stations, not to directly position the first and second bending positions on the terminals. The first and second bending positions are mainly determined by the bending centers and bending structures corresponding to the first and second bending components. By positioning the terminals to be bent at their respective processing stations using the first and second positioning components, the possibility of positional shift during the bending process can be reduced, which helps maintain consistency in the bending positions and shapes of the two bends.

[0049] After being bent a second time by the second bending device 2, the terminal continues to move along the feeding direction with the terminal strip. For ease of explanation, the terminal that needs to be cut off from the terminal strip and inserted into the housing 102 is defined as the insertion terminal 201. The insertion terminal 201 has a front part 202 and a rear part 203 along the insertion direction. The front part 202 is the portion that faces the housing 102 and enters the housing 102 first during insertion, and the rear part 203 is located on the side of the front part 202 away from the housing 102. Figure 11As shown, the portion located to the left of the first bend is the front portion 202 of the insertion terminal 201, and the portion located to the right of the second bend is the rear portion 203 of the insertion terminal 201.

[0050] The mating device 4 includes a pressing assembly, a cutting assembly, and a clamping assembly. After the insertion terminal 201 enters the corresponding insertion station of the mating device 4, the pressing assembly first presses the rear portion 203 of the insertion terminal 201, keeping the insertion terminal 201 stable before it is cut off from the terminal strip. The pressing assembly includes two opposing pressing plates 416, which move towards the insertion terminal 201 and cooperate to press the rear portion 203 of the insertion terminal 201. The cutting assembly includes two second cutters 417, which cooperate to cut the connection between the insertion terminal 201 and the terminal strip, separating the insertion terminal 201 from the terminal strip.

[0051] The clamping insertion assembly includes two push plates 418, which are used to clamp the front part 202 of the insertion terminal 201 from opposite sides. After the insertion terminal 201 is cut off from the terminal strip, the two push plates 418 clamp the front part 202, so that the insertion terminal 201 remains in a controlled state after separation from the terminal strip. After the two push plates 418 have completed clamping the front part 202, the two pressing plates 416 release the pressing on the rear part 203, so that the insertion terminal 201 is held by the clamping insertion assembly; then, the clamping insertion assembly moves towards the housing 102 along the insertion direction, and drives the insertion terminal 201 to move synchronously, so that the insertion terminal 201 is inserted into the corresponding installation position in the housing 102.

[0052] By pressing the rear part 203 of the insertion terminal 201 before it is cut off by the pressing assembly, and clamping the front part 202 of the insertion terminal 201 after it is cut off by the clamping insertion assembly, the insertion terminal 201 can be kept in a controlled state during the cutting off and subsequent insertion process, so as to facilitate the insertion action.

[0053] Therefore, in this embodiment, the terminal is bent twice in opposite directions by the first bending device 1 and the second bending device 2, and then the insertion device 4 completes the pressing, cutting, clamping and insertion of the insertion terminal 201 into the housing 102. This allows the bending and subsequent insertion of the terminal to be completed continuously in the same device. At the same time, the terminal passes through each processing station in the form of a terminal strip along the feeding direction, which can realize the continuous feeding and processing of multiple terminals and reduce the manual transfer and re-clamping of terminals between different processing steps. This helps to simplify the processing flow and improve the continuity, efficiency and consistency of terminal processing.

[0054] See Figure 2 and Figure 3As shown, this embodiment also includes a conveying device 5 and a controller. The conveying device 5 is used to drive the terminal strip to move along the feeding direction, so that the terminal strip enters each processing station sequentially according to a predetermined feeding pitch. The controller is electrically connected to the conveying device 5, the first bending device 1, the second bending device 2, and the insertion device 4, respectively, and is used to coordinate and control the actions of each device according to a preset processing rhythm. Specifically, the controller can control the conveying device 5 to intermittently feed the terminal strip, so that the terminals to be processed move sequentially to the corresponding processing positions of the first bending device 1, the second bending device 2, and the insertion device 4, and control the corresponding device to perform the processing action after the terminal reaches the corresponding processing position. In an embodiment with a cutting device 3, the controller is also electrically connected to the cutting device 3 to control the cutting device 3 to perform the corresponding cutting action.

[0055] Specifically, when the terminal to be bent enters the processing position corresponding to the first bending device 1, the controller controls the first positioning component to position the terminal to be bent and controls the first bending component to complete the first bend. After the terminal strip continues to be fed, the terminal to be bent after the first bend enters the processing position corresponding to the second bending device 2. The controller controls the second positioning component to position the terminal to be bent and controls the second bending component to complete the second bend. When different terminals to be bent on the terminal strip are located at the processing positions corresponding to the first bending device 1 and the second bending device 2, the controller can control the first positioning component and the second positioning component to position them respectively, and control the first bending component and the second bending component to operate synchronously to perform the first bend and the second bend on the corresponding terminal to be bent respectively. After being bent twice, the terminals continue to move with the terminal strip. When a cutting device 3 is installed, the controller controls the cutting device 3 to cut off the designated terminals according to predetermined processing requirements. After the insertion terminals 201 that need to be inserted reach the corresponding insertion station of the insertion device 4, the controller controls the insertion device 4 to sequentially complete the pressing, cutting, clamping, and insertion of the insertion terminals 201 into the housing 102. By coordinating the actions of the conveying device 5 and each processing device, the controller ensures that the feeding of the terminal strip, the two bending of the terminals, and the insertion actions are performed according to a predetermined processing rhythm. When the cutting device 3 is installed, it can also coordinate and control the cutting action of designated terminals, which helps improve the coordination between processing steps and makes the entire processing process more continuous and stable.

[0056] See Figures 8 to 10As shown, the pressing assembly includes two pressing plates 416, the cutting assembly includes two second cutters 417, and the clamping and inserting assembly includes two push plates 418. The two pressing plates 416 are arranged opposite each other to press the rear portion 203 of the insert terminal 201; the two second cutters 417 are used to cut the connection between the insert terminal 201 and the terminal strip; the two push plates 418 are arranged opposite each other to clamp the front portion 202 of the insert terminal 201. Through the above structure, the pressing, cutting, and clamping of the insert terminal 201 can be achieved respectively, to facilitate subsequent inserting operations.

[0057] See Figures 8 to 10 As shown, the mating device 4 includes a fourth frame 41, with two movable plates 411 movably disposed on the fourth frame 41, and the two movable plates 411 capable of reciprocating relative to the fourth frame 41 along the mating direction. A mounting frame 413 is connected between the two movable plates 411, enabling the mounting frame 413 to reciprocate synchronously with the two movable plates 411 along the mating direction, serving as a movable support structure during the mating of the mating terminal 201.

[0058] Two pressing plates 416 and two push plates 418 are movably mounted on the mounting frame 413, allowing the pressing plates 416 and push plates 418 to move along the insertion direction with the mounting frame 413 and to perform corresponding pressing or clamping actions relative to the mounting frame 413. Two second cutters 417 are respectively mounted on the corresponding pressing plates 416, allowing the second cutters 417 to move with the corresponding pressing plates 416 and cooperate to cut the connection between the inserted terminal 201 and the terminal strip.

[0059] With the above structure, the mounting bracket 413 and the two movable plates 411 can be used to drive the clamped insertion terminal 201 to move along the insertion direction, while providing a mounting and movable foundation for the corresponding actions of the pressing plate 416, the second cutter 417 and the push plate 418, so as to cooperate in completing the pressing, cutting, clamping and subsequent insertion of the insertion terminal 201.

[0060] See Figure 9 and Figure 10 As shown, the mating device 4 also includes a rotating shaft 42, a first cam 43, a second cam 44, a third cam 45, and a transmission assembly. The rotating shaft 42 is rotatably mounted on the fourth frame 41. The first cam 43, the second cam 44, and the third cam 45 are all mounted on the rotating shaft 42 and can rotate synchronously with the rotating shaft 42. The three cams respectively form a transmission engagement with the mounting frame 413, the two pressing plates 416, and the two push plates 418 through the transmission assembly to control the movement of the corresponding components.

[0061] Specifically, the first cam 43 is driven by the mounting bracket 413 via a transmission assembly to drive the mounting bracket 413 to reciprocate along the insertion direction with the two movable plates 411; the second cam 44 is driven by the two pressing plates 416 via a transmission assembly to drive the two pressing plates 416 to move toward or away from the insertion terminal 201, so as to press and release the rear part 203 of the insertion terminal 201; the third cam 45 is driven by the two push plates 418 via a transmission assembly to drive the two push plates 418 to move toward or away from the insertion terminal 201, so as to clamp and release the front part 202 of the insertion terminal 201.

[0062] With the above structure, the rotating shaft 42 can simultaneously drive the first cam 43, the second cam 44 and the third cam 45 to rotate, and the three cams drive the mounting bracket 413, the two pressing plates 416 and the two push plates 418 to move through the transmission assembly, respectively, providing a transmission basis for the coordinated action of each component of the mating device 4.

[0063] Furthermore, the mating device 4 also includes a fifth grooved wheel 46, a third servo motor 47, a sixth grooved wheel 48, and a third transmission belt 49. The fifth grooved wheel 46 is connected to the rotating shaft 42. The third servo motor 47 is mounted on the fourth frame 41 and connected to the sixth grooved wheel 48. The third transmission belt 49 connects the fifth grooved wheel 46 and the sixth grooved wheel 48. The third servo motor 47 drives the sixth grooved wheel 48 to rotate, and drives the fifth grooved wheel 46 to rotate via the third transmission belt 49, thereby driving the rotating shaft 42 to drive the first cam 43, the second cam 44, and the third cam 45 to rotate synchronously.

[0064] See Figure 9 and Figure 10 As shown, the transmission assembly includes two first rocker arms 414, two second rocker arms 415, and a transmission rod. A support 412 is provided on the upper and lower sides of the mounting bracket 413, and the two first rocker arms 414 and two second rocker arms 415 are rotatably connected to their respective supports 412. One end of each first rocker arm 414 is movably connected to a second cam 44, and the other end is movably engaged with a corresponding pressing plate 416, so that when the second cam 44 rotates, it can drive the corresponding pressing plate 416 to move through the two first rocker arms 414. One end of each second rocker arm 415 is movably connected to a third cam 45, and the other end is movably engaged with a corresponding push plate 418, so that when the third cam 45 rotates, it can drive the corresponding push plate 418 to move through the two second rocker arms 415.

[0065] One end of the transmission rod is movably connected to the mounting bracket 413, and the other end is movably connected to the first cam 43. When the first cam 43 rotates, it can drive the mounting bracket 413 to reciprocate along the insertion direction through the transmission rod, and the mounting bracket 413 drives the two movable plates 411 to move synchronously. Thus, the first cam 43, the second cam 44, and the third cam 45 transmit power to the mounting bracket 413, the two pressing plates 416, and the two push plates 418 through the transmission rod, the two first rocker arms 414, and the two second rocker arms 415, respectively, so that each component can perform the corresponding reciprocating action, providing a transmission basis for the insertion device 4 to complete the pressing, clamping, and insertion actions.

[0066] See Figure 8 As shown, the pressing plate 416 and the push plate 418 are respectively provided with L-shaped limiting plates 419, and the L-shaped limiting plates 419 form limiting spaces with the corresponding pressing plate 416 or push plate 418. The first swing rod 414 and the second swing rod 415 extend into the corresponding limiting spaces and move in cooperation with them, so that the first swing rod 414 and the second swing rod 415 can drive the corresponding pressing plate 416 and the push plate 418 to reciprocate toward or away from the insertion terminal 201 during the swinging process, so as to realize the pressing and releasing action of the pressing plate 416, and the clamping and releasing action of the push plate 418.

[0067] Meanwhile, the limiting space formed by the L-shaped limiting plate 419 allows the pressing plate 416 and the push plate 418 to reciprocate along the insertion direction with the mounting frame 413. During this movement, the first swing rod 414 and the second swing rod 415 still maintain their active engagement with the corresponding limiting space. Therefore, when the mounting frame 413 moves along the insertion direction, the first swing rod 414 and the second swing rod 415 do not need to disengage from the corresponding pressing plate 416 or push plate 418 to maintain the corresponding transmission engagement relationship. This allows the pressing plate 416 and the push plate 418 to move along the insertion direction with the mounting frame 413 and to perform reciprocating movements toward or away from the insertion terminal 201 under the drive of the corresponding swing rod.

[0068] See Figure 9 and Figure 10 As shown, the first cam 43, the second cam 44, and the third cam 45 are all provided with guide grooves. The transmission rod is movably engaged with the guide groove of the first cam 43. The two first rocker arms 414 are movably engaged with the guide grooves of the second cam 44, and the two second rocker arms 415 are movably engaged with the guide grooves of the third cam 45. The first cam 43, the second cam 44, and the third cam 45 are all mounted on the rotating shaft 42 and can rotate synchronously with the rotating shaft 42. Each guide groove has a different trajectory shape, so that the transmission rod, the two first rocker arms 414, and the two second rocker arms 415 move according to corresponding motion laws under the guidance of the corresponding guide grooves.

[0069] Specifically, the first cam 43 guides the transmission rod to move through its guide groove, and the transmission rod drives the mounting bracket 413 to reciprocate along the insertion direction; the second cam 44 guides the two first rocker arms 414 to swing through its guide groove, and the two first rocker arms 414 respectively drive the two pressing plates 416 to move toward or away from the insertion terminal 201; the third cam 45 guides the two second rocker arms 415 to swing through its guide groove, and the two second rocker arms 415 respectively drive the two push plates 418 to move toward or away from the insertion terminal 201.

[0070] Since the three cams rotate synchronously with the same rotating shaft 42, and the guide grooves on the three cams adopt different trajectory shapes, the mounting bracket 413, the two pressing plates 416 and the two push plates 418 can perform corresponding actions in a predetermined sequence during the rotation of the rotating shaft 42, thereby coordinating the pressing, clamping, releasing the pressing and moving along the insertion direction of the insertion terminal 201, so that the various actions of the insertion device 4 can be connected to each other in a predetermined sequence.

[0071] See Figure 1 , Figure 6 and Figure 7 As shown, this embodiment also includes a cutting device 3 disposed between the second bending device 2 and the insertion device 4. The cutting device 3 is used to cut off designated terminals from the terminal strip after bending by the second bending device 2 according to the processing requirements of the terminal product. The cutting device 3 includes a third frame 31, a third electric cylinder 32, a swing rod 33, two connecting rods 34, and a first cutter 35. The swing rod 33 is rotatably disposed on the third frame 31. The two connecting rods 34 are respectively disposed at both ends of the swing rod 33. One connecting rod 34 connects the third electric cylinder 32 and the swing rod 33, and the other connecting rod 34 connects the swing rod 33 and the first cutter 35. The first cutter 35 is movably disposed on the third frame 31.

[0072] Specifically, when a specific terminal in the terminal strip needs to be cut off, the movable end of the third electric cylinder 32 extends and drives the swing rod 33 to rotate relative to the third frame 31 via the connecting rod 34. After the swing rod 33 rotates, it drives the first cutter 35 to move downward via another connecting rod 34, so that the first cutter 35 acts on the corresponding specific terminal and completes the cutting. After the cutting action is completed, the third electric cylinder 32 resets and drives the first cutter 35 to reset via the two connecting rods 34 and the swing rod 33, so that the terminal strip can continue to move along the feeding direction, so that the insertion terminals 201 that need to be inserted later can enter the corresponding insertion station of the insertion device 4. Through the above transmission structure, the linear motion of the third electric cylinder 32 can be converted into the cutting action of the first cutter 35 via the connecting rod 34 and the swing rod 33, thereby coordinating the continuous processing of the whole machine.

[0073] See Figure 2 and Figure 3As shown, the conveying device 5 includes a fourth servo motor 51, a feeding wheel 52, a first limiting wheel 53, and a second limiting wheel 54. The feeding wheel 52 is connected to the output shaft of the fourth servo motor 51. The outer circumference of the feeding wheel 52 is provided with several feeding teeth, which are adapted to the positioning holes on the terminal strip. When the fourth servo motor 51 drives the feeding wheel 52 to rotate, the feeding teeth on the feeding wheel 52 sequentially engage with the corresponding positioning holes on the terminal strip, thereby causing the terminal strip to move intermittently along the feeding direction according to a predetermined feeding pitch.

[0074] The first limiting wheel 53 and the second limiting wheel 54 have the same structure as the feeding wheel 52, and the centers of the feeding wheel 52, the first limiting wheel 53, and the second limiting wheel 54 are located on the same horizontal straight line along the feeding direction of the terminal strip. When the terminal strip passes through the feeding wheel 52, the first limiting wheel 53, and the second limiting wheel 54, the feeding teeth on each wheel can engage with the positioning holes on the terminal strip. The feeding wheel 52 is used to drive the terminal strip to move, and the first limiting wheel 53 and the second limiting wheel 54 are used to limit and guide the terminal strip, so that the terminal strip moves stably along the predetermined feeding direction. With the above structure, the positioning holes on the terminal strip can be used to realize the feeding and guiding engagement, which is beneficial to allow the terminal strip to enter the corresponding processing station sequentially according to the predetermined feeding pitch, and to complete continuous processing in conjunction with the first bending device 1, the second bending device 2, and the insertion device 4.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
