Description

Technical Field

[0001] The invention relates to the technical field of copper wire processing, in particular to a core pulling device. Background Art

[0002] There are multiple devices in the heat sink assembly system, and each device cooperates with each other to achieve the following functions: unwinding a fixed-length copper wire, cutting a fixed-length copper wire, and extracting the copper core located in the middle of the copper wire. The copper wire with the extracted copper core is conveyed to the welding station to be welded to the metal copper sheet.

[0003] At present, the copper core in the middle of the copper wire is usually extracted manually, that is, the copper core in the middle of the copper wire is exposed manually, and then the copper core is extracted, which has high labor intensity and low efficiency. Summary of the invention

[0009] A reset member is connected between the mounting plate and the second clamping assembly, and is used to provide a pre-tightening force that causes the second clamping assembly to have a tendency to move away from the first clamping assembly.

[0010] By setting the above-mentioned core pulling device, the first end of the copper wire with a copper core is firmly clamped on the first clamping component, and the second end of the copper wire opposite is firmly clamped on the second clamping component, and then the second clamping component is moved along the first direction to make the second clamping component close to the first clamping component. Since the first clamping component and the second clamping component are both clamped on the outer layer of the copper wire, when the second clamping component approaches the first clamping component, it will drive the outer layer of the copper wire to move, exposing the copper core at the second end of the copper wire. The copper core can be directly grasped and pulled out by other devices. When the copper core is pulled out, the second clamping component can also be restored to its original position by the reset member.

[0037] like Figure 1 and Figure 2 As shown, a core pulling device provided in one embodiment of the present invention includes a mounting plate 12 , a first clamping assembly 13 , a second clamping assembly 14 and a resetting member 15 .

[0038] The first clamping assembly 13 is disposed on the mounting plate 12 and is used to clamp the copper wire 200 .

[0039] The second clamping assembly 14 is reciprocatably disposed on the mounting plate 12 along the first direction, and the second clamping assembly 14 and the first clamping assembly 13 are spaced apart along the first direction. The second clamping assembly 14 is used to clamp the copper wire 200 .

[0040] The reset member 15 is connected between the mounting plate 12 and the second clamping assembly 14 , and is used to provide a pre-tightening force that causes the second clamping assembly 14 to have a tendency to move away from the first clamping assembly 13 .

[0041] Please also see Figure 3 By setting the above-mentioned core pulling device, the first end of the copper wire 200 with a copper core is firmly clamped on the first clamping component 13, and the second end of the copper wire 200 is firmly clamped on the second clamping component 14, and then the second clamping component 14 is moved along the first direction to make the second clamping component 14 close to the first clamping component 13. Since the first clamping component 13 and the second clamping component 14 are both clamped on the outer layer of the copper wire 200, when the second clamping component 14 is close to the first clamping component 13, it will drive the outer layer of the copper wire 200 to move, exposing the copper core at the second end of the copper wire 200. When the copper core is exposed, the copper core can be directly grabbed and pulled out by other devices. When the copper core is pulled out, the second clamping component 14 can also be restored to its original position by the reset member 15. In this way, there is no need for manual operation to expose the copper core, which reduces labor intensity and improves production efficiency.

[0042] In some embodiments, the core pulling device further includes a base 10 and a mounting seat 11, the mounting seat 11 is reciprocatably disposed on the base 10 along a second direction perpendicular to the first direction, and the mounting plate 12 is reciprocatably disposed on the mounting seat 11 along the first direction. In this way, the mounting plate 12 can be moved in the first direction and the second direction so that the mounting plate 12 is docked with the copper wire 200 unwinding device, that is, the first clamping assembly 13 and the second clamping assembly 14 on the mounting plate 12 are docked with the copper wire 200 unwinding device.

[0043] The first direction is Figure 2 The first direction is the left-right direction shown in 2, and the second direction is the up-down direction shown in 2.

[0044] In some embodiments, a linear track extending longitudinally along the second direction is provided on the base 10, and a slider is fixedly provided on the mounting seat 11, and the slider is slidably arranged on the linear track, so that the mounting seat 11 can be reciprocated along the second direction and arranged on the base 10. Further, the core pulling device also includes a driving mechanism 16, which is arranged on the base 10 and is transmission-connected to the mounting seat 11 to drive the mounting seat 11 to reciprocate along the second direction.

[0045] It should be noted that the linear rail and the slider are used to make the two structures slide relative to each other. The positions of the linear rail and the slider can be determined according to actual conditions. For example, in the above embodiment, the mounting seat 11 may be provided with a linear rail extending longitudinally along the second direction, and the base 10 may be provided with a slider, and the linear rail is slidably mounted on the slider.

[0046] In actual application, the driving mechanism 16 includes a first driving member 162, a first matching member 164 and a second matching member 166. The first driving member 162 is arranged on the base 10, and the first matching member 164 is transmission-connected to the first driving member 162. The second matching member 166 is arranged on the mounting seat 11 and matches with the first matching member 164. The first driving member 162 drives the second matching member 166 to reciprocate along the second direction through the first matching member 164, thereby indirectly driving the mounting seat 11 to reciprocate along the second direction.

[0047] Specifically, the first driving member 162 is a motor, the first matching member 164 is a gear, and the second matching member 166 is a rack longitudinally arranged along the second direction. The gear is arranged at the driving end of the motor, and the rack and the gear are meshed with each other to convert the rotation of the driving end of the motor into the movement of the rack along the second direction, thereby driving the mounting base 11 to move.

[0048] Of course, in other embodiments, the mounting base 11 can also be driven to reciprocate along the second direction by a pneumatic cylinder or an electric cylinder, but the movement of the mounting base 11 in the second direction can be more accurately controlled by a motor in conjunction with a gear and a rack, so it is preferred that a motor is combined with a gear and a rack.

[0049] In some embodiments, the mounting seat 11 is provided with a slider, and the mounting plate 12 is provided with a linear rail extending longitudinally along the first direction, and the linear rail is slidably arranged on the slider. Further, the core pulling device further includes a second driving member 17, which is arranged on the mounting seat 11 and is transmission-connected with the mounting plate 12 to drive the mounting plate 12 to reciprocate along the first direction.

[0050] In practical applications, the core pulling device further includes a first connecting plate 18, which is connected between the driving end of the second driving member 17 and the mounting plate 12 to achieve transmission connection between the second driving member 17 and the mounting plate 12. Specifically, the second driving member 17 is a cylinder or an electric cylinder.

[0051] In some embodiments, the first clamping assembly 13 includes a first clamping block 132 and a second clamping block 134, and the first clamping block 132 and the second clamping block 134 are sequentially arranged on the mounting plate 12 along the second direction, and the first clamping block 132 and / or the second clamping block 134 can reciprocate along the second direction to approach or move away from each other, thereby clamping or releasing the copper wire 200 located between the first clamping block 132 and the second clamping block 134.

[0052] It should be noted that the copper wire 200 is clamped and released between the first clamping block 132 and the second clamping block 134 by the first clamping block 132 and the second clamping block 134 being close to or away from each other in the second direction. The second clamping block 134 or the first clamping block 132 may be fixed relative to the mounting plate 12, and the first clamping block 132 or the first clamping block 132 may be movable in the second direction, or both the first clamping block 132 and the second clamping block 134 may be movable in the second direction. Preferably, both the first clamping block 132 and the second clamping block 134 are movable in the second direction.

[0053] Furthermore, the first clamping assembly 13 also includes a first elastic member 136, which is connected between the mounting plate 12 and the first clamping block 132 and / or the second clamping block 134, and is used to provide an elastic force to bring the first clamping block 132 and the second clamping block 134 closer to each other.

[0054] The first elastic member 136 provides an elastic force to bring the first clamping block 132 and the second clamping block 134 closer to each other, which actually means that the first elastic member 136 provides a clamping force to clamp the copper wire 200 between the first clamping block 132 and the second clamping block 134. In combination with the above description, when one of the first clamping block 132 and the second clamping block 134 is movable along the second direction, the first elastic member 136 is connected between the movable clamping block and the mounting plate 12, and when both the first clamping block 132 and the second clamping block 134 are movable along the second direction, the first elastic member 136 is connected between the mounting plate 12 and the first clamping block 132 and the second clamping block 134, respectively.

[0055] In actual applications, the first elastic member 136 is a spring, which provides a clamping force for the first clamping block 132 and the second clamping block 134 to clamp the copper wire 200, which is more convenient to adjust, that is, a spring with a suitable stiffness coefficient is selected according to the specifications of the copper wire 200 to avoid excessive elastic force damaging the copper wire 200 or too small elastic force to firmly clamp the copper wire 200.

[0056] At the same time, the number of springs can be multiple. When one of the first clamping block 132 and the second clamping block 134 is movable along the second direction, multiple springs are connected between the corresponding clamping block and the mounting plate 12; when the first clamping block 132 and the second clamping block 134 are both movable, one or more springs can be movably connected between each clamping block and the mounting plate 12. The number of springs can be determined based on the required elastic force and the corresponding stiffness coefficient. It can also be determined that the first clamping block 132 and the second clamping block 134 are both movable along the second direction, which can facilitate the arrangement of more springs, thereby further facilitating the adjustment of the size of the elastic force.

[0057] In some embodiments, the mounting plate 12 is provided with a first opening groove 122 , the first clamping block 132 and the second clamping block 134 are partially located in the first opening groove 122 , and the first elastic member 136 is connected between the inner wall of the first opening groove 122 and the first clamping block 132 and / or the second clamping block 134 .

[0058] It is understandable that if the mounting plate 12 is a plate-like structure and the first clamping block 132 and the second clamping block 134 are arranged on one side surface of the mounting plate 12, it is not convenient for the first elastic member 136 to be directly connected between the mounting plate 12 and the clamping block. Therefore, by opening the first opening groove 122 and partially extending the first clamping block 132 and the second clamping block 134 into the first opening groove 122, the first elastic member 136 is connected between the mounting plate 12 and the first clamping block 132 and / or the second clamping block 134, and the parts of the first clamping block 132 and the second clamping block 134 protruding from the first opening groove 122 are used to clamp the copper wire 200.

[0059] Of course, taking the example that both the first clamping block 132 and the second clamping block 134 are movable, in addition to opening the open groove, two side panels can also be set on one side surface of the mounting plate 12, and the two side panels are arranged at intervals along the second direction. The first clamping block 132 and the second clamping block 134 are set on the same side surface and located between the two side panels, and the first elastic member 136 is connected between the side panel and the first clamping block 132 and the second clamping block 134.

[0060] In some embodiments, the first clamping assembly 13 further includes a first connecting rod 138 , and the first connecting rod 138 is connected to the first clamping block 132 and / or the second clamping block 134 .

[0061] Furthermore, the core pulling device further includes a third driving member 19 and a connecting member 20. The third driving member 19 is disposed on one side of the mounting plate 12. The connecting member 20 is transmission-connected to the third driving member 19 so as to be driven to reciprocate along the second direction. The connecting member 20 can abut against and push the first connecting rod 138 during the reciprocating movement along the second direction, so that the first clamping block 132 and the second clamping block 134 are separated from each other, thereby releasing or facilitating the insertion of the copper wire 200.

[0062] In practical applications, the third driving member 19 is disposed on the mounting seat 11, and the connecting member 20 includes a moving plate 202 and an unlocking plate 204. The moving plate 202 is connected to the driving end of the third driving member 19, and the unlocking plate 204 is fixedly connected to the moving plate 202 and extends along the first direction to overlap with the first connecting rod 138 in the second direction, thereby ensuring that the unlocking plate 204 can abut and push the first connecting rod 138 when moving along the second direction, thereby pushing the first clamping block 132 or the second clamping block 134. Specifically, the third driving member 19 is a pneumatic cylinder or an electric cylinder.

[0063] It should be noted that when the first clamping block 132 and the second clamping block 134 are both movable along the second direction, the first connecting rod 138 includes two first connecting rods 138, the two first connecting rods 138 are respectively connected to the first clamping block 132 and the second clamping block 134, the unlocking plate 204 extends between the two first connecting rods 138, and only one of the connecting rods can be pushed during the movement. Therefore, when the first clamping block 132 and the second clamping block 134 are driven to approach each other by the spring, it is necessary to set the stroke of the spring to ensure that when the copper wire 200 is clamped between the first clamping block 132 and the second clamping block 134, all springs connected to the first clamping block 132 and the second clamping block 134 should provide elastic force, and when the connecting rod drives the first clamping block 132 or the second clamping block 134 to move so that the first clamping block 132 and the second clamping block 134 move away from each other, there will be a gap between the first clamping block 132 and the second clamping block 134, and at this time, part of the spring is compressed, and the other part of the spring is in the original length state.

[0064] In some embodiments, the first clamping block 132 and the second clamping block 134 are partially located in the first opening groove 122, and the remaining portion protrudes from one side of the mounting plate 12, and one end of the first connecting rod 138 is connected to the first clamping block 132 or the second clamping block 134, and the other end passes through the mounting plate 12 to the other side of the mounting plate 12 away from the first clamping block 132 and the second clamping block 134. During the movement of the unlocking plate 204 along the second direction, it can abut against the other end of the first connecting rod 138 away from the first clamping block 132 or the second clamping block 134.

[0065] It should be noted that when the mounting plate 12 has the first opening groove 122 , in order to ensure that the first connecting rod 138 passes through the mounting plate 12 and the first connecting rod 138 moves along the second direction with the first clamping block 132 or the second clamping block 134 , the first opening groove 122 passes through the opposite sides of the mounting plate 12 .

[0066] When the first elastic member 136 is connected between the clamping block and the mounting plate 12 by setting a side plate, strip holes penetrating the mounting plate 12 on opposite sides can also be opened on the mounting plate 12, and the first connecting rod 138 is passed through the corresponding strip holes.

[0067] See also Figure 4 In some embodiments, the first clamping block 132 has the same structure as the second clamping block 134. Further, the first clamping block 132 includes a connecting portion 1322 and a clamping portion 1324 connected to each other, the connecting portion 1322 is reciprocatably disposed in the first opening groove 122 along the second direction, and the clamping portion 1324 protrudes from one side of the mounting plate 12 for clamping the copper wire 200.

[0068] In practical applications, the clamping portion 1324 is still provided with a clamping groove 1321, and the clamping groove 1321 of the first clamping block 132 and the clamping groove 1321 of the second clamping block 134 cooperate to clamp the copper wire 200. Specifically, the clamping groove 1321 is semicircular, and the radius of the clamping groove 1321 is smaller than the radius of the copper wire 200, and larger than the radius of the copper core inside the copper wire 200.

[0069] In some embodiments, when the first opening groove 122 passes through the opposite sides of the mounting plate 12, the first clamping assembly 13 also includes a first clamping plate 139, which is disposed at the first opening groove 122 of the mounting plate 12 and covers the first opening groove 122, and is used to limit the first clamping block 132 and the second clamping block 134 to the first opening groove 122.

[0070] It should be explained that the first clamping block 132 and the second clamping block 134 being limited to the first opening slot 122 means that the first clamping block 132 and the second clamping block 134 will not be separated from the first opening slot 122 during the process of reciprocating movement along the second direction.

[0071] Furthermore, the first clamping plates 139 include multiple pieces, and two first clamping plates 139 are correspondingly arranged for each first opening slot 122 . The corresponding two first clamping plates 139 are arranged on opposite sides of the mounting plate 12 to limit the first clamping block 132 and the second clamping block 134 to slide within the first opening slot 122 .

[0072] In actual application, the first clamping plate 139 is provided with a sliding groove extending along the second direction for the first clamping block 132, the second clamping block 134 and the first connecting rod 138 to pass through, and allows the first clamping block 132, the second clamping block 134 and the first connecting rod 138 to reciprocate along the second direction.

[0073] It can be understood that, when the first opening groove 122 passes through the mounting plate 12, in other embodiments, in order to ensure that the connecting portion 1322 moves stably in the first opening groove 122, the opening sizes of the first opening groove 122 on opposite sides of the mounting plate 12 may be different, and the opening for the clamping portion 1324 to pass through is larger than the opening for the first connecting rod 138 to pass through, so as to ensure that the connecting portion 1322 can be supported at the bottom of the first opening groove 122, so that the connecting portion 1322 can move stably.

[0074] See also Figure 1 and Figure 2 In some embodiments, the second clamping assembly 14 includes a third clamping block 142 and a fourth clamping block 144, and the third clamping block 142 and the fourth clamping block 144 are sequentially arranged on the mounting plate 12 along the second direction, and the third clamping block 142 and / or the fourth clamping block 144 can reciprocate along the second direction to approach or move away from each other, thereby clamping or releasing the copper wire 200 located between the third clamping block 142 and the fourth clamping block 144.

[0075] It should be noted that the design of the third clamping block 142 and the fourth clamping block 144 approaching and moving away from each other to clamp or release the copper wire 200 is the same as that in the first clamping assembly 13, that is, the third clamping block 142 or the fourth clamping block 144 can be movable along the second direction, or both the third clamping block 142 and the fourth clamping block 144 can be movable along the second direction, and preferably both the third clamping block 142 and the fourth clamping block 144 can be movable along the second direction.

[0076] Furthermore, the third clamping block 142 and the fourth clamping block 144 can reciprocate along the first direction, and the reset member 15 is connected between the mounting plate 12 and the third clamping block 142 and the fourth clamping block 144. In this way, the surface layer of the copper wire 200 can be clamped by the third clamping block 142 and the fourth clamping block 144 and moved along the first direction, thereby exposing the copper core at the second end of the copper wire 200.

[0077] In some embodiments, the second clamping assembly 14 further includes a second elastic member 146 connected between the mounting plate 12 and the third clamping block 142 and / or the fourth clamping block 144 to provide elastic force to bring the third clamping block 142 and the fourth clamping block 144 closer to each other.

[0078] In actual applications, the second elastic member 146 and the reset member 15 are both springs. The second elastic member 146 is a spring that can more conveniently adjust the clamping force of the clamped copper wire 200, and the reset member 15 is a spring. When the second clamping assembly 14 is pushed away from the first clamping assembly 13 by the reset member 15, the reset member 15 is always in a compressed state, which can facilitate the reset of the third clamping block 142 and the fourth clamping block 144.

[0079] Of course, there can be multiple springs for the same reason as in the above embodiment, which makes it more convenient to adjust the elastic force, which will not be elaborated here.

[0080] In some embodiments, the mounting plate 12 is further provided with a second opening groove 124, and the second opening groove 124 and the first opening groove 122 are arranged at intervals along the first direction, the third clamping block 142 and the fourth clamping block 144 are partially located in the second opening groove 124, the second elastic member 146 is connected between the inner wall of the second opening groove 124 and the third clamping block 142 and / or the fourth clamping block 144, and the reset member 15 is connected between the inner wall of the second opening groove 124 and the third clamping block 142 and the fourth clamping block 144.

[0081] It needs to be explained that, in the same manner as the setting of the first clamping assembly 13, taking the example that the third clamping block 142 and the fourth clamping block 144 are both movable along the second direction, in addition to opening the open groove, two side panels can also be added to one side of the mounting plate 12 where the first clamping assembly 13 is set. The two added side panels are in the same manner as the two side panels in the above embodiment, but the two groups of side panels are spaced apart in the first direction, and the third clamping block 142 and the fourth clamping block 144 are located between the two added side panels, and the second elastic member 146 is connected between the added side panel and the third clamping member and the fourth clamping member.

[0082] The opening form of the second opening groove 124 is the same as the opening form of the first opening groove 122, the setting form of the second elastic member 146 is also the same as the setting form of the first elastic member 136, the third clamping block 142 and the fourth clamping block 144 have the same structure and are also the same as the first clamping block 132. The difference between the second clamping assembly 14 and the first clamping assembly 13 is that the second clamping assembly 14 is also connected to the reset member 15 and the sizes of the clamping blocks are different. The reset member 15 is used to push the third clamping block 142 and the fourth clamping block 144 away from the first clamping assembly 13 along the first direction.

[0083] Please also see Figure 2 and Figure 5In some embodiments, the second clamping assembly 14 further includes a second connecting rod 148, and the second connecting rod 148 is connected to the third clamping block 142 and / or the fourth clamping block 144. Further, the connecting member 20 can abut against and push the second connecting rod 148 during the reciprocating movement along the second direction, so that the third clamping block 142 and the fourth clamping block 144 are separated from each other, thereby releasing or facilitating the insertion of the copper wire 200.

[0084] In actual application, like the first clamping assembly 13, when the third clamping block 142 and the fourth clamping block 144 are both movable along the second direction, there are two second connecting rods 148, which are respectively connected to the third clamping block 142 and the fourth clamping block 144, and the unlocking plate 204 extends between the two second connecting rods 148, and the unlocking plate 204 extending between the two second connecting rods 148 will also extend between the corresponding two first connecting rods 138 to ensure that the first clamping assembly 13 and the second clamping assembly 14 are driven to move at the same time.

[0085] It should be noted that the first clamping assembly 13 and the second clamping assembly 14 correspond to each other in the first direction, so the first connecting rod 138 and the second connecting rod 148 correspond to each other in the first direction and can be pushed by the same unlocking plate 204 .

[0086] In some embodiments, the second clamping assembly 14 also includes a second clamping plate 141, which is reciprocatably disposed on the mounting plate 12 along the first direction, and the second clamping plate 141 always covers the second opening groove 124 during the reciprocating movement, so as to limit the third clamping block 142 and the fourth clamping block 144 to the second opening groove 124.

[0087] It should be explained that the function of the second clamping plate 141 is the same as that of the first clamping plate 139 , and the only difference is that the second clamping plate 141 can reciprocate along the first direction, which will not be elaborated here.

[0088] In some embodiments, the second clamping assembly 14 further includes a first push rod 149, which is connected to the second clamping plate 141 and extends along the first direction, so that the second clamping assembly 14 and the first clamping assembly 13 can be moved closer to or farther from each other by pushing the first push rod 149 along the first direction to push the second clamping plate 141. At the same time, in combination with the above embodiments, it can be known that the provision of the first push rod 149 is also the difference between the second clamping assembly 14 and the first clamping assembly 13.

[0089] In some embodiments, the first clamping component 13 and the second clamping component 14 each include multiple groups, and the multiple groups of first clamping components 13 and the multiple groups of second clamping components 14 are arranged at intervals along a second direction perpendicular to the first direction, and each first clamping component 13 and a corresponding second clamping component 14 are arranged at intervals along the first direction.

[0090] Multiple groups of clamping assemblies can clamp multiple copper wires 200 at the same time to process multiple copper wires 200, further improving production efficiency. At the same time, the mounting seat 11 is reciprocatably disposed on the base 10 along the second direction, and the mounting plate 12 is reciprocatably disposed on the mounting seat 11 along the first direction. The positions of the multiple groups of clamping assemblies can also be adjusted in the first direction and the second direction to ensure that the multiple groups of clamping assemblies are docked with multiple copper wire 200 unwinding devices or multiple copper wire 200 unwinding positions.

[0091] Furthermore, the movable plate 202 extends longitudinally along the second direction, and the unlocking plate 204 includes a plurality of pieces, and the plurality of unlocking plates 204 are arranged at intervals along the second direction, and each unlocking plate 204 extends into between the two first connecting rods 138 and the two second connecting rods 148 correspondingly, so as to simultaneously drive the plurality of first clamping assemblies 13 and the second clamping assemblies 14 to open, that is, the first clamping block 132 and the second clamping block 134 and the third clamping block 142 and the fourth clamping block 144 move away from each other.

[0092] See also Figure 6 and Figure 7 In some embodiments, the core pulling equipment also includes a grabbing device 30, which is arranged on one side of the mounting plate 12. The grabbing device 30 has a pushing end and a grabbing end. The pushing end and the grabbing end correspond to the second clamping component 14 in the first direction, and both can move back and forth synchronously along the first direction. The pushing end can abut and push the second clamping component 14 during the movement toward the second clamping component 14 along the first direction. The grabbing end is used to grab the copper core in the copper wire 200.

[0093] In this way, when the pushing end and the grabbing end move synchronously along the first direction toward the second clamping assembly 14, the pushing end pushes the second clamping assembly 14 to expose the copper core of the second end of the copper wire 200. After the copper core is exposed, since the grabbing end is also close to the second clamping assembly 14, the copper core can be grabbed by the grabbing end, and then the pushing end and the grabbing end are retracted. During the retraction process, since the copper wire 200 is always clamped in the first clamping assembly 13 and the second clamping assembly 14, the movement of the grabbing end will pull out the copper core.

[0094] In combination with the above embodiments, it can be known that when the pushing end approaches the second clamping assembly 14 along the first direction, the pushing end abuts against the first push rod 149, and when the pushing end is retracted, the second clamping assembly 14 is pushed by the spring. Therefore, the reset member 15 is set as a spring to ensure that the entire second clamping assembly 14 is always abutted against the pushing end during the movement along the first direction, thereby ensuring that the second clamping assembly 14 moves stably.

[0095] Of course, the second clamping assembly 14 can be limited by the second opening groove 124 , that is, the second clamping assembly 14 moves away from the first clamping assembly 13 along the first direction, and after reaching a certain position, it will be limited by the second opening groove 124 and will not move away further.

[0096] It should be noted that Figure 6 and Figure 7 For the gripping device 30, those skilled in the art can determine the position of the gripping device 30 relative to other structures according to the structure and function of the gripping device 30, and it is only necessary to ensure that the gripping device 30 can achieve the above-mentioned function.

[0097] In some embodiments, the grabbing device 30 includes a support 31, a fourth driving member 32, a grabbing mechanism 33 and a second push rod 34. The support 31 is arranged on one side of the mounting plate 12, and the fourth driving member 32 is arranged on the support 31. The grabbing mechanism 33 and the second push rod 34 are both transmission-connected to the first driving member 162 so as to be driven to reciprocate along the first direction. The grabbing mechanism 33 has a grabbing end, and the second push rod 34 has a pushing end.

[0098] In practical applications, the fourth driving member 32 is a cylinder or an electric cylinder, and the grasping mechanism 33 is a clamping claw cylinder for clamping and grasping the copper core.

[0099] Of course, the grasping mechanism 33 also has a grasping state and a releasing state. When the grasping mechanism 33 is in the grasping state, the grasping end of the grasping mechanism 33 can clamp and grasp the copper core, and when the grasping mechanism 33 is in the releasing state, the grasping mechanism 33 can release the grasped copper core.

[0100] In some embodiments, the grabbing device 30 also includes a collecting box 35, which is disposed on the support 31. The grabbing end has an initial position and a grabbing position during the reciprocating movement along the first direction. When the grabbing end is at the initial position, the grabbing end corresponds to the collecting box 35; when the grabbing end is at the grabbing position, the grabbing end can grab the exposed copper core.

[0101] In this way, after grabbing the copper core, the grabbing end returns to the initial position, and then releases the copper core into the collection box 35, which facilitates the collection of the copper core.

[0102] In some embodiments, the grabbing device 30 also includes a second connecting plate 36, which is reciprocatably disposed on the support 31 along the first direction, and the second connecting plate 36 is transmission-connected to the fourth driving member 32, and the grabbing mechanism 33 and the second push rod 34 are both connected to the second connecting plate 36.

[0103] In practical applications, the gripping device 30 further includes a guide rod 37 movably connected to the support 31 along the first direction, and the second connecting plate 36 is fixedly connected to the guide rod 37 , so that the second connecting plate 36 can be ensured to reciprocate more stably along the first direction.

[0104] In some embodiments, the grasping device 30 also includes multiple grasping devices 30 corresponding to multiple groups of second clamping components 14, and each grasping device 30 can correspond to at least two groups of second clamping components 14, that is, at least two grasping mechanisms 33 and second push rods 34 can be set in each grasping device 30, and one second connecting plate 36 and a collecting box 35 can be set, as long as the second push rod 34 can push the corresponding first push rod 149, the grasping mechanism 33 can grasp the corresponding copper core, and the collecting box 35 can collect the copper core.

To make the description concise, not all possible combinations of the technical features in the above-described 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.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
