[0016] Beneficial effects of the present invention: 1. In the initial state of the present application, the lifting mounting plate 1 and the vertical resistance plate are in a state away from the placement notch to avoid affecting the placement of the terminal. Then, after the staff places one end of the terminal in the placement notch, the telescopic end of the electric push rod 1 is extended first, thereby pushing the horizontal resistance plate to move toward the direction close to the terminal until the terminal is clamped between the inner wall of the placement notch and the horizontal resistance plate, completing the preliminary positioning of the terminal. Then, the telescopic end of the electric push rod 2 is contracted, driving the lifting mounting plate 1 and the vertical resistance plate to approach the terminal until the vertical resistance plate is in contact with the outer surface of one end of the terminal, thereby further positioning the terminal. At this time, the terminal is also limited and fixed through the cooperation of the horizontal resistance plate and the vertical resistance plate, which is easy to operate.

[0017] 2. In the initial state, the translation seat is in a position away from the placement seat to avoid affecting the staff's placement of the terminal on the placement slot. When the terminal is placed, the horizontal contact plate and the vertical contact plate limit and fix the terminal. The translation seat moves to the front of the terminal under the action of the driving mechanism. At this time, the arc-shaped placement slot is aligned with the terminal. At this time, the staff can place the enameled wire to be used in the arc-shaped placement slot, and then push the enameled wire in the direction close to the terminal until the end of the enameled wire is inserted into the terminal. The operation is convenient. At this time, the terminal is received through the cooperation of the translation seat and the receiving plate. The staff does not need to hold the enameled wire all the time, which saves effort.

[0018] 3. In the initial state, the contact wheel is away from the translation seat to avoid affecting the placement of the enameled wire. When the enameled wire is placed in the arc-shaped placement groove and one end of the enameled wire is inserted into the terminal, the lifting mechanism drives the U-shaped frame and the contact wheel to move downward until the contact groove on the contact wheel presses on the upper surface of the enameled wire, limiting and fixing the enameled wire to prevent the enameled wire from falling off the terminal when the welding assembly is performing welding operations. When the welding assembly welds the terminal and the enameled wire together, the horizontal contact plate and the vertical contact plate are both away from the terminal, releasing the limit fixation of the terminal. At this time, since the contact wheel presses on the upper surface of the enameled wire, the enameled wire and the terminal It will not fall from the translation seat, and then the resistance wheel rotates in the opposite direction under the action of the working motor, causing the enameled wire and the terminal to move in the direction away from the placement seat until one end of the terminal is out of the placement groove, and then the translation seat moves in the direction close to the guide plate with the enameled wire, the terminal and the resistance wheel. When the terminal moves to above the guide plate, the resistance wheel rotates forward, thereby driving the enameled wire and the terminal to move away from the translation seat. After the terminal and the enameled wire move to the guide plate, the guide plate and the side baffle cooperate to further guide and unload the welded terminal and enameled wire. During this process, the staff places a new terminal on the placement groove of the placement seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the initial state of the present application, the lifting installation plate 1 6 and the vertical contact plate 7 are in a state away from the placement notch 3 to avoid affecting the placement of the terminal 40. Then, after the staff places one end of the terminal 40 in the placement notch 3, the telescopic end of the electric push rod 1 5 is extended first, thereby pushing the horizontal contact plate 4 toward the direction close to the terminal 40 until the terminal 40 is clamped between the inner wall of the placement notch 3 and the horizontal contact plate 4, completing the preliminary positioning of the terminal 40. Then, the telescopic end of the electric push rod 2 8 is retracted, driving The lifting mounting plate 6 and the vertical contact plate 7 are close to the terminal 40 until the vertical contact plate 7 contacts the outer surface of one end of the terminal 40, thereby further positioning the terminal 40. At this time, the terminal 40 is also limited and fixed by the cooperation of the horizontal contact plate 4 and the vertical contact plate 7, which is easy to operate. Then the staff can insert one end of the enameled wire 41 used in conjunction with the auxiliary placement component into the terminal 40, and then the welding component works to weld the terminal 40 and the enameled wire 41 together.

[0024] The auxiliary placement component includes a translation seat 9 movably arranged above the workbench 1. The upper end surface of the translation seat 9 is provided with a snap-fit ​​groove, and a receiving plate 10 is detachably arranged in the snap-fit ​​groove. The upper end surface of the receiving plate 10 is provided with an arc-shaped placement groove 11. A driving mechanism for cooperating with the translation seat 9 is provided on the workbench 1.

[0025] In the initial state, the translation seat 9 is in a position away from the placement seat 2 to avoid affecting the staff's placement of the terminal 40 on the placement groove 3. When the terminal 40 is placed, the horizontal contact plate 4 and the vertical contact plate 7 limit and fix the terminal 40. The translation seat 9 moves to the front of the terminal 40 under the action of the driving mechanism. At this time, the arc placement groove 11 is aligned with the terminal 40. At this time, the staff can place the enameled wire 41 to be used in conjunction with it into the arc placement groove 11, and then push the enameled wire 41 in the direction close to the terminal 40 until the end of the enameled wire 41 is inserted into the terminal 40. The operation is convenient. At this time, the terminal 40 is received through the cooperation of the translation seat 9 and the receiving plate 10. The staff does not need to hold the enameled wire 41 all the time, which saves effort.

[0026] The driving mechanism includes two sliding grooves 12 opened on the upper end surface of the workbench 1, and a sliding block 13 is slidably arranged in each sliding groove 12. A connecting bracket 14 is fixed to the upper end surface of each sliding block 13, and the upper end surface of the connecting bracket 14 is fixedly connected to the lower end surface of the translation seat 9. A driving unit is provided on the workbench 1 for use with the sliding block 13.

[0027] In the initial state, the translation seat 9 is at a position away from the placement seat 2. When the translation seat 9 needs to be moved closer to the placement seat 2, the driving unit drives the sliding block 13 to move toward the placement seat 2, thereby driving the connecting bracket 14 and the translation seat 9 to move closer to the placement seat 2.

[0028] The drive unit includes two screw rods 15 rotatably arranged in corresponding sliding grooves 12. Each screw rod 15 is threaded through the corresponding sliding block 13. A drive box for use with the screw rods 15 is provided on the workbench 1. The drive box is existing technology.

[0029] When the translation seat 9 needs to be translated, the driving box drives the screw rod 15 to rotate, thereby driving the sliding block 13 to produce a corresponding displacement, and the sliding block 13 drives the connecting bracket 14 and the translation seat 9 to move together.

[0030] A U-shaped frame 16 is provided above the translation seat 9 for lifting and lowering movement. A resistance wheel 17 is rotatably provided on the inner wall of the U-shaped frame 16. A resistance groove 18 is provided on the outer surface of the resistance wheel 17. A working motor 19 used in conjunction with the resistance wheel 17 is fixed to one side of the U-shaped frame 16. A lifting mechanism used in conjunction with the U-shaped frame 16 is provided on the translation seat 9.

[0031] In the initial state, the interference wheel 17 is away from the translation seat 9 to avoid affecting the placement of the enameled wire 41. When the enameled wire 41 is placed in the arc-shaped placement groove 11 and one end of the enameled wire 41 is inserted into the terminal 40, the lifting mechanism drives the U-shaped frame 16 and the interference wheel 17 to move downward until the interference groove 18 on the interference wheel 17 is pressed on the upper surface of the enameled wire 41, limiting and fixing the enameled wire 41 to prevent the enameled wire 41 from falling off from the terminal 40 when the welding assembly is performing welding operations.

[0032] The lifting mechanism includes a lifting mounting plate 20 fixed to the upper end surface of the U-shaped frame 16. Two electric push rods 3 21 are symmetrically fixed to the upper end surface of the translation seat 9. The ends of the telescopic ends of the electric push rods 3 21 are fixedly connected to the lower end surface of the lifting mounting plate 20.

[0033] In the initial state, the telescopic end of the electric push rod three 21 is in an extended state. When the contact wheel 17 needs to move downward, the telescopic end of the electric push rod three 21 contracts, thereby driving the lifting mounting plate two 20, the U-shaped frame 16 and the contact wheel 17 to move downward until the contact wheel 17 is pressed on the upper surface of the enameled wire 41.

[0034] A material guide plate 22 is obliquely provided above the workbench 1 , with side baffles 23 fixed on both sides of the material guide plate 22 , and a support rod 24 fixed between the lower end surface of the material guide plate 22 and the workbench 1 .

[0035] After the welding assembly welds the terminal 40 and the enameled wire 41 together, the horizontal contact plate 4 and the vertical contact plate 7 are both away from the terminal 40, releasing the limit fixation of the terminal 40. At this time, since the contact wheel 17 is pressed on the upper surface of the enameled wire 41, the enameled wire 41 and the terminal 40 will not fall off the translation seat 9. Then the contact wheel 17 rotates in the opposite direction under the action of the working motor 19, causing the enameled wire 41 and the terminal 40 to move in the direction away from the placement seat 2 until one end of the terminal 40 is out of the placement groove 3, and then the translation seat 9 with the enameled wire 41 is released. The wire 41, the terminal block 40 and the contact wheel 17 are translated toward the direction close to the guide plate 22. When the terminal block 40 moves to above the guide plate 22, the contact wheel 17 rotates forward, thereby driving the enameled wire 41 and the terminal block 40 to move away from the translation seat 9. After the terminal block 40 and the enameled wire 41 move onto the guide plate 22, the guide plate 22 and the side baffle 23 cooperate to further guide and unload the welded terminal block 40 and the enameled wire 41. During this process, the staff places the new terminal block 40 on the placement groove 3 of the placement seat 2.

[0036] The enameled wire 41 has a certain hardness.

[0037] The welding assembly includes a fixed upper electric push rod 25 and a lower electric push rod 26. An L-shaped connecting frame 27 is fixed to the upper end face of the placement seat 2. The upper electric push rod 25 is fixed through the L-shaped connecting frame 27. The end of the telescopic end of the upper electric push rod 25 is fixed with an upper lifting plate 28. The lower end face of the upper lifting plate 28 is fixed with an upper electrode 29. The upper end face of the workbench 1 is provided with a second sinking groove. The lower electric push rod 26 is fixed in the second sinking groove. The end of the telescopic end of the lower electric push rod 26 is fixed with a lower lifting plate 30. The upper end face of the lower lifting plate 30 is fixed with a lower electrode 31.

[0038] When one end of the enameled wire 41 is inserted into the terminal block 40, the telescopic ends of the upper electric push rod 25 and the lower electric push rod 26 extend at the same time, thereby driving the corresponding upper lifting plate 28 and the lower lifting plate 30 to move, thereby prompting the upper electrode 29 and the lower electrode 31 to approach each other until the terminal block 40 is squeezed and welded, thereby welding the terminal block 40 and the end of the enameled wire 41 together, and the working principle of welding is the existing technology.

[0039] An upper air extraction and purification unit and a lower air extraction and purification unit are provided on the workbench 1. The upper air extraction and purification unit includes two upper connecting blocks 32. The upper connecting block 32 is fixed to the lower end surface of the upper lifting plate 28. The lower ends of the two upper connecting blocks 32 are fixed with the same upper arc-shaped air extraction hood 33. The upper end surface of the L-shaped connecting frame 27 is fixed with an upper purification box 34. An upper ventilation hose 35 is provided between the air inlet end of the upper purification box 34 and the upper arc-shaped air extraction hood 33. The air outlet end of the upper purification box 34 is connected to an external air extraction pump. The upper ventilation hose 35 is long enough.

[0040] When the upper electrode 29 and the lower electrode 31 cooperate to perform welding operations, the upper exhaust purification unit and the lower exhaust purification unit work to extract and purify the fume and the like generated by welding.

[0041] The lower air extraction purification unit includes two lower connecting blocks 36, which are fixed to the upper end surface of the lower lifting plate 30. The upper ends of the two lower connecting blocks 36 are fixed with the same lower arc-shaped exhaust hood 37. The upper end surface of the workbench 1 is fixed with a lower purification box 38. A lower ventilation hose 39 is provided between the air inlet end of the lower purification box 38 and the lower arc-shaped exhaust hood 37. The air outlet end of the lower purification box 38 is connected to the external exhaust pump 2, and the lower ventilation hose 39 is long enough.

[0042] When the upper lifting plate 28 and the upper electrode 29 move toward the direction close to the terminal 40, the upper lifting plate 28 drives the upper connecting block 32 and the upper arc-shaped exhaust hood 33 to move downward together. When the lower lifting plate 30 and the lower electrode 31 move toward the direction close to the terminal 40, the lower lifting plate 30 drives the lower connecting block 36 and the lower arc-shaped exhaust hood 37 to move upward together until the upper arc-shaped exhaust hood 33 and the lower arc-shaped exhaust hood 37 are docked together and sleeved on the outer surface of the enameled wire 41. Then, the exhaust pump 1 and the exhaust pump 2 work to generate air flow, and the fume generated by welding is sucked into the upper arc-shaped exhaust hood 33 and the lower arc-shaped exhaust hood 37, and then enters the corresponding upper purification box 34 and the lower purification box 38 through the upper ventilation hose 35 and the lower ventilation hose 39, so as to prevent the fume generated by welding from polluting the air environment.

[0043] When the present invention is in use, in the initial state, the lifting installation plate 1 6 and the vertical contact plate 7 are in a state away from the placement notch 3 to avoid affecting the placement of the terminal 40. Then, after the staff places one end of the terminal 40 in the placement notch 3, the telescopic end of the electric push rod 1 5 is extended first, thereby pushing the horizontal contact plate 4 to move toward the direction close to the terminal 40 until the terminal 40 is clamped between the inner wall of the placement notch 3 and the horizontal contact plate 4, completing the preliminary positioning of the terminal 40. Then, the telescopic end of the electric push rod 2 8 is retracted, and the terminal 40 is brought into contact with the terminal 40. The movable lifting mounting plate 16 and the vertical contact plate 7 are moved close to the terminal 40 until the vertical contact plate 7 contacts the outer surface of one end of the terminal 40, thereby further positioning the terminal 40. At this time, the cooperation between the horizontal contact plate 4 and the vertical contact plate 7 also limits and fixes the terminal 40, which is easy to operate. Then, the staff can insert one end of the enameled wire 41 used in conjunction with the auxiliary placement component into the terminal 40, and then the welding component works to weld the terminal 40 and the enameled wire 41 together; In the initial state, the translation seat 9 is in a position away from the placement seat 2 to avoid affecting the staff from placing the terminal 40 on the placement slot 3. When the terminal 40 is placed, the horizontal contact plate 4 and the vertical contact plate 7 limit and fix the terminal 40. The translation seat 9 moves to the front of the terminal 40 under the action of the driving mechanism. At this time, the arc placement groove 11 is aligned with the terminal 40. At this time, the staff can place the enameled wire 41 to be used in conjunction with the arc placement groove 11, and then push the enameled wire 41 in the direction close to the terminal 40 until the end of the enameled wire 41 is inserted into the terminal 40. The operation is convenient. At this time, the terminal 40 is received by the cooperation of the translation seat 9 and the receiving plate 10. The staff does not need to hold the enameled wire 41 all the time, which saves effort. In the initial state, the contact wheel 17 is away from the translation seat 9 to avoid affecting the placement of the enameled wire 41. When the enameled wire 41 is placed in the arc-shaped placement groove 11 and one end of the enameled wire 41 is inserted into the terminal 40, the lifting mechanism drives the U-shaped frame 16 and the contact wheel 17 to move downward until the contact groove 18 on the contact wheel 17 presses on the upper surface of the enameled wire 41, thereby limiting and fixing the enameled wire 41, thereby preventing the enameled wire 41 from falling off from the terminal 40 during the welding operation of the welding assembly; After the welding assembly welds the terminal 40 and the enameled wire 41 together, the horizontal contact plate 4 and the vertical contact plate 7 are both away from the terminal 40, releasing the limit fixation of the terminal 40. At this time, since the contact wheel 17 is pressed on the upper surface of the enameled wire 41, the enameled wire 41 and the terminal 40 will not fall off the translation seat 9. Then the contact wheel 17 rotates in the opposite direction under the action of the working motor 19, causing the enameled wire 41 and the terminal 40 to move in the direction away from the placement seat 2 until one end of the terminal 40 is out of the placement groove 3, and then the translation seat 9 with the enameled wire 41 is released. The wire 41, the terminal block 40 and the contact wheel 17 are translated toward the direction close to the guide plate 22. When the terminal block 40 moves to above the guide plate 22, the contact wheel 17 rotates forward, thereby driving the enameled wire 41 and the terminal block 40 to move away from the translation seat 9. After the terminal block 40 and the enameled wire 41 move onto the guide plate 22, the guide plate 22 and the side baffle 23 cooperate to further guide and unload the welded terminal block 40 and the enameled wire 41. During this process, the staff places the new terminal block 40 on the placement groove 3 of the placement seat 2.
