Description

Technical Field

[0001] The present invention relates to the field of welding teeth for saw blades, and particularly to a solder strip feeding system and a solder strip electric bending and cutting mechanism thereof. Background Art

[0002] As is well known, a tooth welding machine is a device for welding a cutter head made of a superhard material (such as, but not limited to, diamond or alloy) onto a pre-processed tooth of a saw blade. By welding the cutter head to the tooth of the saw blade, the wear resistance of the saw blade can be greatly improved and its service life can be extended.

[0003] Currently, in the process of welding the cutter head to the saw blade by the tooth welding machine, it involves the step of pre-transferring a solder strip (i.e., solder) onto the tooth; when the cutter head and the tooth clamp the solder strip, the cutter head and the tooth can be fixed together by melting the solder strip.

[0004] Among them, for the solder strip, it is made by first bending and then cutting a strip-shaped solder, so it is required that the tooth welding machine is equipped with a bending device for bending the strip-shaped solder and a device for cutting the bent strip-shaped solder.

[0005] However, the bending device and the cutting device in the existing tooth welding machine are independent of each other and each is provided with a power source, so the device for making the solder strip has the defects of complex structure, high cost and difficult control.

[0006] In addition, in the process of transferring the solder strip to the tooth, it also involves the up-and-down picking and placing of the solder strip and the horizontal transfer of the solder strip, so it is required that the tooth welding machine is equipped with a horizontal transfer device and a lifting transfer device assembled and connected to the horizontal transfer device to meet the need for directional sliding of the solder strip.

[0007] However, the horizontal transfer device and the lifting transfer device in the existing tooth welding machine are either composed of a motor, a lead screw, a nut and a sliding seat, or composed of a motor, a pulley, a belt and a sliding seat; in this way, two sets of devices composed of a motor, a lead screw, a nut and a sliding seat or composed of a motor, a pulley, a belt and a sliding seat are required for the transfer of the solder strip, resulting in the defects of complex structure, high cost and difficult control (requiring precise coordinated control of two motors) for the device responsible for transferring the solder strip.

[0008] Therefore, there is an urgent need for a solder strip feeding system and a solder strip electric bending and cutting mechanism thereof to overcome one or more of the above defects. Summary of the Invention

[0009] An object of the present invention is to provide a solder strip electric bending and cutting mechanism with simple structure, low cost and easy control.

[0010] Another object of the present invention is to provide a solder strip feeding system with simple structure, low cost and easy control.

[0011] To achieve the above object, the solder tab electric bending and cutting mechanism of the present invention includes a mechanism base body, a knife plate and a driving motor assembled on the mechanism base body, and a first cutter and a second cutter that can perform punching and cutting cooperation along a first axis. The first cutter and the knife plate are arranged opposite to each other along the first axis to define a channel for a strip-shaped solder to be conveyed through along a second axis perpendicular to the first axis; the second cutter is stacked on the knife plate along the second axis and is provided with a receiving space, and the receiving space penetrates through the side of the second cutter facing the knife plate; the driving motor is configured to drive the second cutter to perform reciprocating linear sliding along the first axis so that the second cutter has at least a first to a third working position. The receiving space is aligned with the channel at the first working position to feed a preset length of the strip-shaped solder into the receiving space. During the process of the second cutter switching from the first working position to the second working position, the preset length of the strip-shaped solder fed into the receiving space is bent around the knife plate to form a bent section. During the process of the second cutter switching from the second working position to the third working position, the strip-shaped solder that is a preset distance beyond the second cutter in the bent section is cut through the cooperation with the first cutter.

[0012] Compared with the prior art, by virtue of "the first cutter and the knife plate are arranged opposite to each other along the first axis to define a channel", "the second cutter is stacked on the knife plate along the second axis and is provided with a receiving space, and the receiving space penetrates through the side of the second cutter facing the knife plate", and "the driving motor is configured to drive the second cutter to perform reciprocating linear sliding along the first axis so that the second cutter has at least a first to a third working position", the receiving space is aligned with the channel at the first working position to feed a preset length of the strip-shaped solder into the receiving space. During the process of the second cutter switching from the first working position to the second working position, the preset length of the strip-shaped solder fed into the receiving space is bent around the knife plate to form a bent section. During the process of the second cutter switching from the second working position to the third working position, the strip-shaped solder that is a preset distance beyond the second cutter in the bent section is cut through the cooperation with the first cutter, thereby obtaining a solder tab; that is to say, the driving motor can achieve the purpose of bending and cutting the strip-shaped solder to obtain a solder tab by driving the second cutter to perform reciprocating linear sliding relative to the first cutter. Therefore, the solder tab electric bending and cutting mechanism of the present invention can simplify the structure, reduce the cost and facilitate precise control.

[0013] To achieve the above object, the solder tab feeding system of the present invention includes a solder tab transfer mechanism and the aforementioned solder tab electric bending and cutting mechanism, and the first cutter and the solder tab transfer mechanism are arranged in sequence along the direction in which the second cutter switches from the second working position to the third working position.

[0027] In order to elaborate in detail on the technical content and structural features of the present invention, the following further description is provided in conjunction with the embodiments and with reference to the drawings.

[0028] Please refer toFigure 1 , the solder tab feeding system 1000 of the present invention includes a solder tab transfer mechanism 100 and a solder tab electric bending and cutting mechanism 400. The solder tab electric bending and cutting mechanism 400 is configured to bend and cut the strip-shaped solder 300a to obtain Figure 13e the solder tabs 300 as shown; the solder tab transfer mechanism 100 is configured to grasp the solder tabs 300 produced by the solder tab electric bending and cutting mechanism 400 and transfer the solder tabs 300 to the next working station, and the state is shown in Figure 8e ; alternatively, in Figure 8e , as an example, the solder tab transfer mechanism 100 places the solder tabs 300 on the tool head, but not limited thereto; in addition, a solder conveying mechanism 500 for conveying the strip-shaped solder 300a is assembled on the mechanism base 410 described below. The solder conveying mechanism 500 is located between the mechanism base 410 and the grasping member 30b described below along the first axis described below, and the state is shown in Figure 1 .

[0029] Combined with Figures 9 to 11 as shown, the solder tab electric bending and cutting mechanism 400 includes a mechanism base 410, a tool plate 420 assembled on the mechanism base 410, a driving motor 430, and a first cutter 440 and a second cutter 450 that can perform punching and cutting cooperation along the first axis (the Z-axis direction in the attached drawing). The first cutter 440 and the tool plate 420 are arranged opposite to each other along the first axis. For example, the first cutter 440 is located directly above the tool plate 420, so that the first cutter 440 and the tool plate 420 define a channel 460 for the strip-shaped solder 300a to be conveyed through along the second axis (the Y-axis direction in the attached drawing) perpendicular to the first axis. The second cutter 450 is stacked on the tool plate 420 along the second axis, so that the second cutter 450 can be in close contact with the tool plate 420. The second cutter 450 is also provided with a receiving space 451, and the receiving space 451 penetrates through the side of the second cutter 450 facing the tool plate 420; alternatively, in Figure 13a , as an example, the receiving space 451 also penetrates through the side of the second cutter 450 facing away from the tool plate 420, so that the receiving space 451 is arranged to completely penetrate the second cutter 450; in addition, in Figure 12 , the receiving space 451 is a square space, but not limited thereto. The driving motor 430 is configured to drive the second cutter 450 to perform reciprocating linear sliding along the first axis, so that the second cutter 450 has at least a first to a third working station. The receiving space 451 is aligned with the channel 460 at the first working station shown in Figure 13a to feed the strip-shaped solder 300a into the receiving space 451 by a preset length 310a, and the state is shown in Figure 13b ; the second cutter 450 switches from the first working station shown in Figure 13a to Figure 13cDuring the process of the second working station shown, the preset length 310a of the strip solder 300a fed into the receiving space 451 is bent around the knife plate 420 to form a bent section 310, and the state is shown in Figure 13c shown; the second cutter 450 is in Figure 13c During the process of switching from the second working station shown to Figure 13e the third working station shown, the strip solder 300a at a preset distance beyond the second cutter 450 in the bent section 310 is cut by cooperating with the first cutter 440, that is, when the bent section 310 is at a preset distance beyond the second cutter 450, at this time, the second cutter 450 cooperates with the first cutter 440 to cut the strip solder 300a, so as to obtain Figure 13e the solder tab 300 with the bent section 310 in. It should be noted that the aforementioned preset length 310a and preset distance are determined according to the size of the solder tab 300 to be manufactured and are well known in the art, so they will not be elaborated here. In addition, for the specific structure of the solder tab electric bending and cutting mechanism 400, please refer to the following description.

[0030] As Figure 1 and Figures 9 to 12 shown, the first cutter 440, the knife plate 420 and the driving motor 430 are arranged in sequence along the first axis, that is, in Figures 9 to 10 the first cutter 440, the knife plate 420 and the driving motor 430 are arranged from top to bottom in sequence, but not limited to Figures 9 to 10 shown. The driving motor 430 is a rotary motor, and a rotary wheel 432 is assembled on the output end 431 of the rotary motor. An eccentric structure 433 is arranged on the rotary wheel 432 eccentrically with respect to the rotation center line C of the rotary wheel 432. The second cutter 450 has a matching structure 452 that matches with the eccentric matching 433. The rotary wheel 432 drives the second cutter 450 to perform reciprocating linear sliding through the cooperation of the eccentric structure 433 and the matching structure 452 under the drive of the rotary motor 430. Such a design enables the driving motor 430 to only rotate in a single direction during the reciprocating linear sliding of the second cutter 450, effectively avoiding the driving motor 430 from making frequent forward and reverse rotations. Specifically, in Figures 9 to 12Among them, as an example, the output end 431 of the rotating electric machine and the rotation center line C of the rotating wheel 432 each extend along the second axial direction. The cooperating structure 452 is a linkage long slot hole. The eccentric structure 433 protrudes from the rotating wheel 432 along the second axial direction. The eccentric structure 433 is fitted into the linkage long slot hole and can slide along the linkage long slot hole. The linkage long slot hole extends along a third axial direction (see the X-axis direction in the attached drawing) perpendicular to the second axial direction. The first axial direction, the second axial direction, and the third axial direction together form the X-axis direction, the Y-axis direction, and the Z-axis direction in a three-dimensional coordinate system, so as to ensure that the rotating wheel 432 can more reliably drive the second cutter 450 to perform reciprocating linear sliding along the first axial direction during the rotation around the rotation center line C arranged along the second axial direction. More specifically, in Figures 9 to 12 Among them, as an example, the solder tab electric bending and cutting mechanism 400 further includes a first supporting member 470 and a second supporting member 480 that are assembled on the mechanism base 410 and configured to support the rotating wheel 432, so as to increase the supporting strength of the rotating wheel 432 and effectively prevent the rotating wheel 432 from being distorted due to excessive force exerted by the second cutter 450. In addition, the wheel center line of the rotating wheel 432 coincides with the rotation center line C to ensure that the rotating wheel 432 rotates around its own wheel center line. For example, in Figure 12 Among them, as an example, the first supporting member 470, the second supporting member 480, and the eccentric structure 433 are each a bearing structure. Of course, according to actual needs, the first supporting member 470, the second supporting member 480, and the eccentric structure 433 can also be wheel structures or round shaft structures, so it is not limited by Figure 12 the shown. It should be noted that in other embodiments, the eccentric structure 433 can be a cam profile. Correspondingly, the cooperating structure 452 moves along the cam profile during the rotation of the rotating wheel 432, and thus is pushed by the cam profile to perform reciprocating linear sliding. In addition, the driving electric machine 430 can also be a linear electric machine, and the second cutter 450 performs reciprocating linear sliding through the frequent forward and reverse rotation of the linear electric machine. In addition, when the driving electric machine 430 is a rotating electric machine, at this time, the second cutter 450 can also be driven to perform reciprocating linear sliding through the cooperation of a gear and a linear rack, where the gear is installed on the output end 431 of the driving electric machine 430, and the linear rack is fixed to the second cutter 450.

[0031] As Figure 1 and Figures 9 to 12 shown, the mechanism base 410 includes a first base 411 that extends along the second axial direction and is located between the driving electric machine 430 and the tool plate 420, and a second base 412 that extends along the first axial direction, so that the first base 411 and the second base 412 are perpendicular to each other, and the first base 411 and the second base 412 are fixedly connected. Optionally, in Figure 9 and Figure 10As an example, the first base 411 and the second base 412 are fixedly connected at the ends so that the first base 411 and the second base 412 provide more positions for the installation of external components. Of course, the first base 411 and the second base 412 can also be fixedly connected at other positions, so it is not limited by Figure 9 and Figure 10 As shown. The drive motor 430 is assembled on the second base 412, and the second base 412 provides support and an assembly place; the knife plate 420 is fixedly connected to the first base 411, and the first base 411 provides support and an assembly place for the knife plate 420. The first base 411 is provided with an avoidance space 4111 for the second cutter 450 to pass through the first base 411, so that the second cutter 450 can pass through the first base 411 and be assembled and connected to the eccentric structure 433; at this time, the first cutter 440 is assembled on the knife plate 420, and the knife plate 420 provides support and an assembly place for the first cutter 440. Among them, to facilitate the assembly of the second cutter 450 and limit the second cutter 450 to only slide along the first axis, in Figure 9 and Figure 10 as an example, the solder tab electric bending and cutting mechanism 400 further includes a cover plate 490 stacked with the knife plate 420 along the second axis, and the second cutter 450 is located in the space 491 surrounded by the cover plate 490 and the knife plate 420; of course, according to actual needs, a linear space can also be provided on the knife plate 420 to directly control the second cutter 450 to only slide linearly along the first axis. At this time, the cover plate 490 can be deleted, so it is not limited by Figure 9 and Figure 10 As shown; in addition, in order to ensure that the second cutter 450 is in close contact with the knife plate 420 and does not affect the bending of the preset length 310a, an avoidance cavity 421 is provided on the side of the knife plate 420 facing the second cutter 450, so as to facilitate the second cutter 450 to bend the preset length 310a around the knife plate 420 to form a bent section 310 by means of the avoidance cavity 421.

[0032] Please refer to Figures 1 to 6, the first cutting knife 440 and the solder transfer mechanism 100 are arranged in sequence along the direction in which the second cutting knife 450 is switched from the second working position to the third working position (the positive direction of the Z-axis direction in the attached drawing), so that the solder transfer mechanism 100 is arranged above the corresponding position of the first cutting knife 440; and the solder transfer mechanism 100 includes a mechanism frame 10, a rotating motor 20, a winding transmission member 30a, a grasping member 30b, a first sliding body 40, a second sliding body 50, and a first runner 61, a second runner 62, a third runner 63, and a fourth runner 64 that are arranged in sequence at the four vertices of a convex quadrilateral on the mechanism frame 10. The first runner 61 is aligned with the second runner 62 along the third axial direction (the X-axis direction in the attached drawing); the first runner 61 is aligned with the fourth runner 64 along the first axial direction (the Z-axis direction in the attached drawing), and the second runner 62 is aligned with the third runner 63 along the first axial direction. The winding transmission member 30a is wound around the first runner 61 to the fourth runner 64 to meet the requirement that the winding transmission member 30a makes a rotational motion around the first to fourth runners 64. The first sliding body 40 is located outside the winding transmission member 30a and slides along the third axial direction on the mechanism frame 10, the second sliding body 50 slides along the first axial direction on the first sliding body 40 and is assembled and connected to the winding transmission member 30a, and the grasping member 30b is assembled to the second sliding body 50. The rotating motor 20 is assembled to the mechanism frame 10, and the mechanism frame 10 provides a supporting function and an assembly place for the rotating motor 20. The rotating motor 20 is configured to drive the first to fourth runners 64 to rotate together and drive the winding transmission member 30a to rotate. The rotating winding transmission member 30a drives the second sliding body 50, the grasping member 30b, and the first sliding body 40 to slide together along the third axial direction and drives the second sliding body 50 and the grasping member 30b to slide relative to the first sliding body 40 along the first axial direction, so as to realize the transfer of the solder 300 obtained by the solder electric bending and cutting mechanism 400 to the next working position by the grasping member 30b; for example, in Figure 8a , the second sliding body 50 slides forward along the positive direction of the Z-axis direction in sequence to Figure 8b and Figure 8c the shown state, and then the second sliding body 50 slides forward along the positive direction of the X-axis direction to Figure 8d the shown state, and then slides backward along the negative direction of the Z-axis direction to Figure 8e the shown state, so as to realize the purpose of transferring the solder 300 obtained by the solder electric bending and cutting mechanism 400 to the next working position by the grasping member 30b; in addition, the previous description of "at the four vertices of a convex quadrilateral" means that the projections of the centerlines of the first runner 61 to the fourth runner 64 in the axial direction (the Y-axis direction in the attached drawing) exactly form the four vertices of a convex quadrilateral. More specifically, as follows:

[0033] As Figures 1 to 6As shown, the grasping member 30b is a vacuum suction nozzle, so that the grasping member 30b grasps the solder pad 300 in an adsorption manner. Of course, according to actual needs, the grasping member 30b can also be a clamping jaw or other structures, so it is not limited by Figures 1 to 6 what is shown.

[0034] As Figures 7 to 8e shown, the diameters of the first runner 61 to the fourth runner 64 are the same, so that they are arranged in turn at the four vertices of a square. Specifically, in Figures 2 to 3 , and Figures 7 to 8e , as an example, the first runner 61 to the fourth runner 64 are synchronous belt wheels, and the winding transmission member 30a is a synchronous belt to ensure that the winding transmission member 30a and the first runner 61 to the fourth runner 64 perform precise synchronous movement; of course, according to actual needs, the first runner 61 to the fourth runner 64 can also be sprockets, and correspondingly, the winding transmission member 30a is a chain, so it is not limited by Figures 2 to 3 and Figures 7 to 8e what is shown.

[0035] As Figures 2 to 6 shown, the first sliding body 40, the second sliding body 50 and the first to fourth runners 64 are all located at the first side 11 of the mechanism frame 10. The second sliding body 50 is arranged separately from the first to fourth runners 64 along the axial direction of the first runner 61 (that is, the second axial direction) to prevent the first to fourth rotations 64 from obstructing the sliding of the second sliding body 50; in addition, the rotating motor 20 is located at the opposite second side 12 of the mechanism frame 10, so that the first sliding body 40, the second sliding body 50 and the first to fourth runners 64 are arranged on the mechanism frame 10 on opposite sides relative to the rotating motor 20, avoiding the influence of the rotating motor 20 on the sliding of the second sliding body 50, and making the arrangement of the first sliding body 40, the second sliding body 50, the rotating motor 20 and the first to fourth runners 64 on the mechanism frame 10 more reasonable and compact; and the output end 21 of the rotating motor 20 is assembled and connected to the first runner 61, so that the first runner 61 is used as the driving wheel, and the second to fourth runners 64 are used as the follower wheels; therefore, when the rotating motor 20 works, the rotating motor 20 drives the first runner 61 to rotate, and the rotating first runner 61 drives the second to fourth runners 64 to perform synchronous movement through the winding transmission member 30a, and while the first to fourth runners 64 are moving, the winding transmission member 30a performs synchronous rotary movement.

[0036] As Figure 4 and Figure 5As shown, an adjustment seat 70 and an adjustment operating rod 80 extending along the third axis are provided at the second side 12 of the mechanism frame 10. The adjustment seat 70 is slidably arranged along the third axis on the second side 12 of the mechanism frame 10. The adjustment operating rod 80 is rotatably assembled to the mechanism frame 10. The adjustment operating rod 80 also extends into the adjustment seat 70 and is threadedly connected to the adjustment seat 70. Additionally, the mechanism frame 10 is also provided with an avoidance space 13 and an avoidance space 14 penetrating therethrough. The second runner 62 passes through the avoidance space 13 and is assembled on the adjustment seat 70. The third runner 63 passes through the avoidance space 14 and is assembled on the adjustment seat 70. By rotating the adjustment operating rod 80, the positions of the adjustment seat 70, the second runner 62 and the third runner 63 on the adjustment seat 70 on the mechanism frame 10 can be changed, thereby changing the distances between the first runner 61 and the second runner 62 and between the fourth runner 64 and the third runner 63, achieving the purpose of tensioning the wound transmission member 30a and facilitating the assembly and disassembly operations of the wound transmission member 30a.

[0037] As Figure 2 shown in FIGS. 8d to 8e, a linear guide rail 15 extending along the third axis is provided on the first side 11 of the mechanism frame 10. The linear guide rail 15 is located outside the wound transmission member 30a and is also located beside both the third runner 63 and the fourth runner 64. A linear slider 41 slidably connected to the linear guide rail 15 is assembled on the first sliding body 40. By means of the cooperation of the linear guide rail 15 and the linear slider 41, the sliding support ability of the mechanism frame 10 for the first sliding body 40 is increased, so that the sliding of the first sliding body 40 is more stable and smoother. Additionally, a guide slider 42 is fixed on the side of the first sliding body 40 facing the second sliding body 50. The second sliding body 50 is slidably connected to the guide slider 42 to increase the smoothness and stability of the second sliding body 50 sliding relative to the first sliding body 40. Both ends of the second sliding body 50 extend out of the guide slider 42 to facilitate the assembly connection of one end of the second sliding body 50 to the wound transmission member 30a and the assembly connection of the other end of the second sliding body 50 to the grasping member 30b. For example, in Figures 7 to 8e one example, the upper end of the second sliding body 50 is assembled to the wound transmission member 30a, and the lower end of the second sliding body 50 is assembled to the grasping member 30b, but not limited thereto.

[0038] As Figures 2 to 3 , and Figures 6 to 8eAs shown, the solder tab transfer mechanism 100 further includes a pin shaft member 91 and a tensioning wheel 92. One end of the pin shaft member 91 is inserted into the second sliding body 50, and the other end of the pin shaft member 91 is inserted into the wound transmission member 30a, so as to simplify the assembly connection structure of the pin shaft member 91 with the second sliding body 50 and the wound transmission member 30a respectively. The tensioning wheel 92 is assembled at the first side 11 of the mechanism frame 10, and the mechanism frame 10 provides a supporting effect on the tensioning wheel 92; the tensioning wheel 92 also abuts against the wound transmission member 30a at the position between the third and fourth runners 64. Optionally, as an example, the tensioning wheel 92 abuts against the wound transmission member 30a from the outside at the position between the third and fourth runners 64, so as to increase the wrap angle of the wound transmission member 30a with the third runner 63 and the fourth runner 64 respectively, thereby effectively ensuring the precise reliability of the synchronous rotation of the first to fourth runners 64. Specifically, as an example, the tensioning wheel 92 is arranged with adjustable position along the first axial direction, so as to facilitate the operator to adaptively adjust the position of the tensioning wheel 92 according to the tightness of the wound transmission member 30a.

[0039] Combined with Figure 1 and Figures 8a to 8e , the working principle of the solder tab transfer mechanism for grasping the solder tabs manufactured by the solder tab electric bending and cutting mechanism and transferring them to the next working station is described as follows: As Figure 8a shown, when the grasping member 30b completes grasping the solder tabs 300 manufactured by the solder tab electric bending and cutting mechanism 400, at this time, the rotating motor 20 drives the first runner 61 to rotate. The rotating first runner 61 drives the second to fourth runners 64 to rotate synchronously through the wound transmission member 30a. At the same time, the wound transmission member 30a makes a rotary motion around the first to fourth runners 64. The rotating wound transmission member 30a drives the second sliding body 50 and the grasping member 30b to sequentially slide along the positive direction of the Z axis through the pin shaft member 91 to the Figure 8b and Figure 8c shown state; and when the second sliding body 50 slides from the Figure 8a shown state to the Figure 8c shown state, in addition to sliding relative to the first sliding body 40, the second sliding body 50 and the grasping member 30b also drive the first sliding body 40 to make an adaptive slide along the positive direction of the X axis. The state is shown in Figure 8c ; then, the wound transmission member 30a continues to drive the second sliding body 50, the grasping member 30b and the first sliding body 40 to slide together along the positive direction of the X axis through the pin shaft member 91 to the Figure 8d shown state; finally, the wound transmission member 30a continues to drive the second sliding body 50, the grasping member 30b and the first sliding body 40 to slide together to the Figure 8e shown state; and when the second sliding body 50 and the grasping member 30b are in the Figure 8dslip to the state shown Figure 8e During the process of slipping to the state shown, the second sliding body 50 and the gripper 30b also slide relative to the first sliding body 40 in the reverse direction along the Z-axis, so as to achieve the purpose of transferring the solder tab 300 grabbed from the solder tab electric bending and cutting mechanism 400 to the next working station. It should be noted that when the pin shaft 91 wound around the transmission member 30a is located between the first runner 61 and the fourth runner 64 or between the second runner 62 and the third runner 63, the rotating transmission member 30a wound around can drive the second sliding body 50 and the gripper 30b to slide relative to the first sliding body 40 along the Z-axis through the pin shaft 91; when the pin shaft 91 wound around the transmission member 30a is located between the first runner 61 and the second runner 62, the rotating transmission member 30a wound around can drive the second sliding body 50, the gripper 30b and the first sliding body 40 to slide along the X-axis through the pin shaft 91. It is worth noting that during the process of transferring the solder tab 300 grabbed from the solder tab electric bending and cutting mechanism 400 to the next working station, although Figures 8a to 8e the movement path of the pin shaft 91 shown is an annular path with open ends, however, according to actual needs, the movement path of the pin shaft 91 can be designed as a closed-loop path, that is to say, the wound transmission member 30a is designed to be driven by a unidirectional working rotating motor 20 to make a 360-degree rotation, so it is not limited by Figures 8a to 8e shown; in addition, to further improve the smoothness of the solder tab electric bending and cutting mechanism 400 being grabbed by the solder tab transfer mechanism 100, before the second cutter 450 cuts off the strip-shaped solder 300a, the gripper 30b first grabs the strip-shaped solder 300a with a preset distance beyond the second cutter 450 from above the second cutter 450 at the bending section 310, and then moves forward in the positive direction of the first axis with the solder tab 300 after the second cutter 450 and the first cutter 440 cooperate to cut off the solder tab 300, so as to ensure that the solder tab 300 cut and manufactured by the solder tab electric bending and cutting mechanism 400 remains at the gripper 30b and is conveyed by the gripper 30b.

[0040] Among them, in the solder transfer mechanism 100, by means of "the first runner 61, the second runner 62, the third runner 63 and the fourth runner 64 arranged in sequence according to the four vertices of a convex quadrilateral on the mechanism frame 10, the first runner 61 is aligned with the second runner 62 along the third axis, the first runner 61 is aligned with the fourth runner 64 along the first axis, the second runner 62 corresponds to the third runner 63 along the first axis, the winding transmission member 30a is wound around the first runner 61 to the fourth runner 64, the first sliding body 40 is located outside the winding transmission member 30a and slides along the third axis on the mechanism frame 10, and the second sliding body 50 slides on the first sliding body 40 and is assembled and connected to the winding transmission member 30a", such a design enables the rotation motor 20 to drive the first to fourth runners 64 to rotate together and drive the winding transmission member 30a to rotate during operation. The rotating winding transmission member 30a drives the second sliding body 50 together with the gripping member 30b and the first sliding body 40 to slide along the third axis and drives the second sliding body 50 and the gripping member 30b to slide relative to the first sliding body 40, so as to achieve the purpose of transferring the solder 300 grabbed from the solder electric bending and cutting mechanism 400 to the next working station; therefore, the number of rotation motors 20 used is reduced and the structure is simplified, thus achieving the purpose of reducing costs and being easy to control.

[0041] Compared with the prior art, by means of "the first cutter 440 and the knife plate 420 are arranged opposite to each other along the first axis to define a channel 460", "the second cutter 450 is stacked on the knife plate 420 along the second axis and is provided with a receiving space 451, and the receiving space 451 penetrates through the side of the second cutter 450 facing the knife plate 420", and "the driving motor 430 is configured to drive the second cutter 450 to perform a reciprocating linear slide along the first axis so that the second cutter 450 has at least the first to third working positions", the receiving space 451 is aligned with the channel 460 at the first working position to supply the strip solder 300a to be fed into the receiving space 451 by a preset length 310a, and the second cutter 450 bends the preset length 310a of the strip solder 300a fed into the receiving space 451 around the knife plate 420 to form a bent section 310 during the process of switching from the first working position to the second working position. The second cutter 450 cuts the strip solder 300a that has passed a preset distance beyond the second cutter 450 in the bent section 310 by cooperating with the first cutter 440 during the process of switching from the second working position to the third working position, so as to obtain the solder 300; that is to say, the driving motor 430 can achieve the purpose of bending and cutting the strip solder 300a to obtain the solder 300 by driving the second cutter 450 to perform a reciprocating linear slide relative to the first cutter 440. Therefore, the solder electric bending and cutting mechanism 400 can simplify the structure, reduce costs and facilitate precise control.

[0042] It should be noted that although the Z-axis direction is shown as the first axial direction, the Y-axis direction as the second axial direction, and the X-axis direction as the third axial direction in the accompanying drawings, it is not limited thereto.

[0043] The above-disclosed are only the preferred examples of the present invention, and the scope of the rights of the present invention cannot be limited thereby. Therefore, all equivalent changes made according to the claims of the present invention fall within the scope covered by the present invention.
