The drive unit 11 and the PCBA board 13 are connected by the positive and negative conductive leads 12. The drive unit 11 includes a coupling 101 and a motor 102. One end of the motor 102 is connected to the coupling 101, and the other end of the motor 102 is connected to both the positive and negative conductive leads 12.

[0003] In the entire assembly process of the shaver, the positive and negative conductive leads 12 need to be soldered to the motor 101 of the drive unit 11. Then, the conductive leads 12 soldered to the motor 101 need to be soldered to the PCBA board 13. During the soldering process, the wires (positive and negative conductive leads 12) need to be fed and soldered. The existing technology uses manual feeding of the conductive leads 12 and hand-held conductive leads 12 for manual soldering, which has the problems of high labor costs and long operation time.

For those skilled in the art, the specific meaning of the terms in this invention can be understood according to the specific circumstances.

[0050] See Figure 1-20 The automatic shaver welding machine disclosed in this invention includes a drive unit welding device 100 and a PCBA welding device 200; the output end of the drive unit welding device 100 is connected to the input end of the PCBA welding device 200 and inputs a drive unit 11 with positive and negative conductive leads 12 welded to the PCBA welding device 200.

[0051] The drive unit welding device 100 includes a wire supply mechanism (not shown in the figure), a lead wire stripping mechanism 180, a lead wire loading mechanism 110, a drive unit welding turntable 120, multiple drive unit carriers 130, a top-opening loading and unloading mechanism 140, a drive unit welding mechanism 150, a drive unit unloading and conveying mechanism 160, and a drive unit unloading and conveying mechanism 170. The top-opening loading and unloading mechanism 140 includes a top-opening loading assembly 1401 and a top-opening unloading assembly 1402. The multiple drive unit carriers 130 are fixed to the drive unit welding turntable 120. Driven by the drive unit welding turntable 120, the drive unit carriers 130 rotate sequentially from the loading station to the loading station, welding station, and unloading station to load the drive units 11 into the drive unit carriers 130. The lead wire loading mechanism 110 and the top-opening mechanism 140 are connected to the drive unit welding turntable 150. A wire mounting assembly 1401 is located at the online workstation. The top-opening wire mounting assembly 1401 is used to open the clamping area of ​​the drive unit carrier 130 so that the drive unit carrier 130 can clamp the conductive lead 12 input by the lead wire online mechanism 110 in the clamping area. The drive unit welding mechanism 150 is located at the welding workstation and is used to weld the conductive lead 12 to the drive unit. The drive unit unloading and conveying mechanism 160 and the top-opening wire unloading assembly 1402 are located at the unloading workstation. The top-opening wire unloading assembly 1402 is used to cooperate with the drive unit carrier 130 to open and release the clamped conductive lead 12 so that the drive unit unloading and conveying mechanism 160 can output the drive unit with the welded conductive lead 12 on the drive unit carrier 130 to the drive unit unloading and conveying mechanism 170.

[0052] The PCBA soldering device 200 includes a PCBA soldering turntable 210, multiple razor carriers 220, a PCBA soldering mechanism 230, and a razor unloading mechanism 240. The multiple razor carriers 220 are fixed to the PCBA soldering turntable 210. The razor carriers 220 are used to position the PCBA board with the drive unit assembled to a preset position. The drive unit unloading conveyor mechanism, the PCBA soldering mechanism 230, and the razor unloading mechanism 240 are arranged sequentially on the outer periphery of the PCBA soldering turntable 210 along the rotation direction of the PCBA soldering turntable 210. The PCBA soldering mechanism 230 is used to solder the conductive leads to the PCBA board. The razor unloading mechanism 240 is used to output the razor after the PCBA board soldering is completed.

[0053] The drive unit welding device of this solution uses a drive unit welding turntable 120 to rotate and transport the drive unit carrier 130 sequentially to the loading station for loading conductive leads 12 into the drive unit carrier 130, the loading station for loading drive units 11 into the drive unit carrier 130, the welding station for welding drive units 11 and conductive leads 12, and the unloading station for unloading drive units 11 with welded conductive leads 12. The welding process, as well as the loading, loading, and unloading of conductive leads 12, require no manual intervention, improving operational accuracy and work efficiency. The conductive leads 12 are supplied by a wire supply mechanism, and after the plastic outer shells at both ends of the conductive leads 12 are peeled off by the lead stripping mechanism 180, the conductive leads 12 are loaded onto the drive unit carrier 130 by the lead loading mechanism 110 for welding. The loading and unloading of conductive leads 12 onto and off the drive unit carrier 130 are achieved by the top-opening wire loading assembly 1401 and the top-opening wire unloading assembly 1402, respectively, realizing automatic wire loading and unloading operations. The drive unit unloading conveyor mechanism 170 transmits the drive unit 11 with soldered conductive leads 12 to the unloading point via a conveyor belt, so as to transport it to the PCBA soldering device 200.

[0054] The drive unit 11 with the soldered conductive leads 12 is manually assembled with the PCBA board 13 and placed on the shaver carrier 220 of the PCBA soldering turntable 210 to pre-position the drive unit 11 and the PCBA board 13. Driven by the PCBA soldering turntable 210, the drive unit 11 and the PCBA board 13 are rotated to the underside of the PCBA soldering mechanism 230. The PCBA soldering mechanism 230 then solders the positive and negative conductive leads 12 onto the PCBA board 13 in sequence to form the bare shaver. Finally, the bare shaver is unloaded by the shaver unloading mechanism 240.

[0055] In this solution, the welding of one end of the conductive lead 12 to the drive unit 11 and the welding of the other end of the conductive lead 12 to the PCBA board 13 of the automatic shaver welding machine are both automated operations, which can minimize manual operation, improve welding accuracy and work efficiency.

[0056] See further Figure 13-15 The lead wire launching mechanism 110 includes an upper wire translation component 111, an upper wire lateral adjustment component 112, an upper wire lifting component 113, and an upper wire clamp 114. The upper wire lateral adjustment component 112 is connected to the output end of the upper wire translation component 111, the upper wire lifting component 113 is connected to the output end of the upper wire lateral adjustment component 112, and the upper wire clamp 114 is connected to the output end of the upper wire lifting component 113.

[0057] The upper wire clamp 114 includes an upper wire rotation drive assembly 1141 and an upper wire clamp assembly 1142. The upper wire rotation drive assembly 1141 is connected to the output end of the upper wire lifting assembly 113, and the upper wire clamp assembly 1142 is located at the output end of the upper wire rotation drive assembly 1141. The upper wire rotation drive assembly 1141 is used to drive the upper wire clamp assembly 1142 to rotate to the wire picking position to clamp the conductive lead 12, and to drive the upper wire clamp assembly 1142 to rotate to the upper wire position to release the conductive lead 12 into the lead clamp 132.

[0058] In this solution, the upper clamp 114, driven by the upper line translation component 111, the upper line lateral adjustment component 112, and the upper line lifting component 113, can achieve position adjustment and movement in three-dimensional space, facilitating precise alignment of the upper clamp 114 with the conductive lead 12 at the feeding and discharging positions. The upper line rotation drive component 1141 can rotate and adjust the orientation of the conductive lead 12 clamped by the upper clamp 114, so that the placement of the conductive lead 12 at the feeding position on the upper clamp 114 differs from that at the discharging position. The lead-feeding mechanism 110 of this solution integrates adjustments along the X, Y, and Z axes as well as the rotation direction, facilitating precise control of the alignment effect of the conductive lead 12 during loading and unloading, reducing manual operation, simplifying the structure, and enabling precise automatic control.

[0059] See Figure 15 The upper line translation component 111 includes an upper line translation drive 1111, an upper line translation slide 1112, and an upper line translation slide plate 1113. The slide rails of the upper line translation drive 1111 and the upper line translation slide 1112 are fixed to the machine base (not shown in the figure). The upper line translation slide plate 1113 is connected to the output end of the upper line translation drive 1111 and the slider of the upper line translation slide 1112.

[0060] In this embodiment, the upper line lateral adjustment component 112 includes an upper line lateral adjustment drive 1121 and an upper line lateral adjustment bracket 1122. The upper line lateral adjustment drive 1121 is fixed to the upper line translation slide plate 1113, and the upper line lateral adjustment bracket 1122 is connected to the output end of the upper line lateral adjustment drive 1121. The moving direction of the upper line lateral adjustment bracket 1122 and the moving direction of the upper line translation slide plate 1113 are perpendicular to each other on the horizontal plane. The upper line lateral adjustment component 112 in this solution is a lateral fine-tuning structure, which can be adjusted manually. Specifically, the upper line lateral adjustment drive 1121 can be an adjusting screw with a handle, and the upper line lateral adjustment bracket 1122 is provided with an internal thread structure that matches the external thread of the adjusting screw. Understandably, during installation, the lead wire feeding mechanism 110 of this solution is positioned between the wire supply mechanism and the lead wire clamp 132 in the lateral direction, eliminating the need for extensive lateral movement. The lateral adjustment component 112 allows for fine-tuning of the lateral position. This saves space and facilitates operation.

[0061] In this embodiment, the upper line lateral adjustment bracket 1122 includes a horizontal sliding plate 11221 and a vertical sliding plate 11222 vertically fixed to the horizontal sliding plate 11221. The horizontal sliding plate 11221 is fixedly connected to the upper line lateral adjustment drive component 1121 and slidably connected to the upper line translation slide plate 1113. The upper line lifting component 113 is connected to the vertical sliding plate 11222. The vertical sliding plate 11222 facilitates the installation of the upper line lifting drive component 1131.

[0062] In this embodiment, the upper line lifting assembly 113 includes an upper line lifting drive 1131 and an upper line lifting slide plate 1132. The upper line lifting drive 1131 is fixed on the upper line horizontal adjustment bracket 1122, and the upper line lifting slide plate 1132 is connected to the output end of the upper line lifting drive 1131.

[0063] See Figure 14The upper line rotation drive assembly 1141 includes an upper line rotation drive component 11411 and an upper line rotation coupling 11412. The upper line rotation drive component 11411 is connected to the output end of the upper line lifting assembly 113, the upper line rotation coupling 11412 is connected to the output end of the upper line rotation drive component 11411, and the upper line clamp assembly 1142 is connected to the upper line rotation coupling 11412. The upper line rotation drive component 11411 is used to drive the upper line clamp assembly 1142 to rotate 90 degrees in a single operation. Normally, the wire supply mechanism supplies the stripped conductive lead 12 to the wire clamp 114 in a horizontal manner. However, due to the subsequent welding operation of the drive unit 11, the drive unit 11 needs to be placed in a flat position in the drive unit carrier 130. Therefore, the conductive lead 12 will be clamped vertically in the lead clamp 132. Thus, the wire clamp 114 needs to adjust the horizontal position by the upper wire horizontal adjustment component 112, adjust the height by the upper wire lifting component 113, and adjust the wire orientation by the upper wire rotation drive component 1141 to place the stripped conductive lead 12 in the lead clamp 132.

[0064] In this embodiment, the upper wire clamp assembly 1142 includes an upper wire clamp opening and closing drive 11421 and two upper wire movable clamps 11422. The two upper wire movable clamps 11422 are respectively connected to the two output ends of the upper wire clamp opening and closing drive 11421, and a clamping area for holding the conductive lead 12 is formed between the two upper wire movable clamps 11422. It can be understood that the conductive lead 12 is a cylindrical wire structure, and the clamping area is also cylindrical, that is, each of the two upper wire movable clamps 11422 is provided with a semi-cylindrical groove, and the two grooves combined form the clamping area.

[0065] See Figure 9-11 The drive unit carrier 130 includes a drive unit base 131 and a lead wire clamp 132 connected to the drive unit base 131. The drive unit base 131 is used to support and position the drive unit 11, and the lead wire clamp 132 is used to clamp the conductive lead wire 12 to be soldered onto the drive unit 11.

[0066] See further Figure 12 The top-opening wire loading assembly 1401 and the top-opening wire unloading assembly 1402 of this solution have the same structure, both including a top-opening driving component 141 and a top-opening component 142. The top-opening component 142 is connected to the output end of the top-opening driving component 141 and is used to apply force to the lead clamp 132 to open the lead clamp 132 to load or unload the conductive lead 12.

[0067] In this solution, the top-opening wire-installing assembly 1401 or the top-opening wire-removing assembly 1402 clamps the positive and negative conductive leads 12 placed by the lead wire insertion mechanism 110, respectively, using lead wire clamps. The drive unit carrier 130 carries the drive unit 11, causing the motor 102 of the drive unit 11 to extend towards the lead wire clamp 132. The positive and negative electrodes of the motor 102 then pass through the positive and negative conductive leads 12 held by the lead wire clamp 132, respectively. When placing the conductive leads 12, the top-opening wire-installing assembly 140... The top part 142 of the top opening and unloading assembly 1402 opens the lead clamp 132, allowing the conductive lead 12 to be inserted into the lead clamp 132; after the conductive lead 12 is soldered onto the motor 102 and when the drive unit 11 needs to be removed from the drive unit carrier 130, the top part 142 of the top opening assembly 1401 / top opening and unloading assembly 1402 opens the lead clamp 132, allowing the conductive lead 12 to be removed from the lead clamp 132, at which point the drive unit 11 can be removed from the drive unit carrier 130. This solution utilizes the cooperation between the top-opening wire mounting assembly 1401 and the lead wire clamp 132 to install the conductive lead wire 12, aligning it with the position of the motor 102 for further welding. The cooperation between the top-opening wire unloading assembly 1402 and the lead wire clamp 132 facilitates the removal of the conductive lead wire 12, allowing the drive unit unloading and conveying mechanism 160 to remove the drive unit 11 with the welded conductive lead wire 12. The welding process, as well as the wire mounting, unmounting, and unmounting processes of the conductive lead wire 12, require no manual intervention, resulting in a simpler structure.

[0068] The drive unit 11 includes a coupling 101 and a motor 102. The drive unit base 131 includes a clearance groove 1311, a receiving groove 1312, and a lead wire clamp groove 1313. The receiving groove 1312 connects the clearance groove 1311 and the lead wire clamp groove 1313. The clearance groove 1311 is used to support the coupling 101, the receiving groove 1312 is used to position the motor 102, and the lead wire clamp groove 1313 is used to accommodate the lead wire clamp 132. The clearance groove 1311, the receiving groove 1312, and the lead wire clamp groove 1313 on the drive unit base 131 are designed to facilitate the positioning of the coupling 101, the motor 102, and the positive and negative conductive leads 12. Each of the receiving grooves 1312 is provided with a first magnet block 1314, which is used to attract the axial wall of the motor 102 to position the motor 102, and prevent the motor 102 from shifting in the receiving groove 1312 when the drive unit base 131 rotates to different positions, causing the conductive lead 12 to come out of the electrode of the motor 102, which facilitates the welding of the motor 102 and the conductive lead 12.

[0069] In this embodiment, the lead clamp 132 includes a clamp mounting base 1321, a clamp guide rod 1322, a clamp translation slide block 1323, a movable lead clamp 1324, and a fixed lead clamp 1325. The clamp mounting base 1321, the clamp translation slide block 1323, and the fixed lead clamp 1325 are respectively fixed to the drive unit base 131. The movable lead clamp 1324 is fixed to the slider of the clamp translation slide block 1323. The two ends of the clamp guide rod 1322 are respectively fixedly connected to the clamp mounting base 1321 and the movable lead clamp 1324. A clamping area for holding the conductive lead 12 is formed between the movable lead clamp 1324 and the fixed lead clamp 1325. The movable lead clamp 1324 is provided with a lead groove, and a clamping area is formed between the lead groove of the movable lead clamp 1324 and the fixed lead clamp 1325. The clamp mounting base 1321, clamp guide rod 1322, clamp translation slide block 1323, lead wire movable clamp 1324, and lead wire fixing clamp 1325 are provided for positioning the conductive lead wire 12.

[0070] The lead wire fixing clamp 1325 is provided with a second magnet block 13251 facing the receiving groove 1312. The second magnet block 13251 is used to attract the end of the motor 102 with electrodes to position the motor 102, and further prevent the motor 102 from shifting in the receiving groove 1312 when the drive unit base 131 rotates to different positions, causing the conductive lead wire 12 to fall out of the electrodes of the motor 102, which facilitates the welding of the motor 102 and the conductive lead wire 12.

[0071] Specifically, the lead clamp 132 includes two clamp mounting bases 1321, two clamp guide rods 1322, a clamp translation slide block 1323, two lead movable clamps 1324, and a lead fixing clamp 1325. The clamp translation slide block 1323 and the lead fixing clamp 1325 are respectively fixed to the drive unit base 131. The two clamp mounting bases 1321 are symmetrically arranged on both sides of the lead fixing clamp 1325. The two lead movable clamps 1324 are both fixed to the slider of the clamp translation slide block 1323. One end of the two clamp guide rods 1322 is respectively fixedly connected to the corresponding clamp mounting base 1321, and the other end of the two clamp guide rods 1322 is respectively fixedly connected to the corresponding lead movable clamp 1324. The two lead movable clamps 1324 and the lead fixing clamp 1325 respectively form two clamping areas for holding conductive leads 12. This design uses two lead clamps 1324 to clamp the positive conductive lead 12 and the negative conductive lead 12 respectively.

[0072] See Figure 12The top-opening drive component 141 includes a top-opening loading and unloading line base 1411 and a top-opening loading and unloading line lifting drive component 1412. The top-opening loading and unloading line lifting drive component 1412 is fixed to the top-opening loading and unloading line base 1411, and the top palm component 142 is connected to the output end of the top-opening loading and unloading line lifting drive component 1412.

[0073] In this embodiment, the top clamp component 142 includes a top clamping support plate 1421, a top clamping rod 1422, and a force application part 1423. The lead wire movable clamp 1324 is provided with a force receiving part 13241. The top clamping support plate 1421 is connected to the output end of the top clamping drive component 141. One end of the top clamping rod 1422 is fixed to the top clamping support plate 1421, and the other end of the top clamping rod 1422 is connected to the force application part 1423. The force application part 1423 is used to apply a force to the force receiving part 13241 to make the lead wire movable clamp 1324 slide on the clamp translation slide block 1323.

[0074] In one embodiment, the force-applying part 1423 is a sliding wheel rotatably connected to the top rod 1422 of the loading / unloading line, and the force-receiving part 13241 is a wedge-shaped force-receiving surface including a first force-receiving surface parallel to the horizontal plane and a second force-receiving surface intersecting the horizontal and vertical planes. The first force-receiving surface is located on the side closer to the lead wire fixing clamp 1325. After the roller surface of the sliding wheel contacts the first force-receiving surface, it slides into the second force-receiving surface. The second force-receiving surface is inclined to the force-applying direction of the force-applying part 1423, so that when the force-applying part 1423 applies force upward, the second force-receiving surface is driven by the force applied by the force-applying part 1423 to move the lead wire movable clamp 1324 backward, so that the lead wire movable clamp 1324 moves away from the lead wire fixing clamp 1325, so as to facilitate the insertion of the conductive lead wire 12 between the lead wire movable clamp 1324 and the lead wire fixing clamp 1325. When the conductive lead 12 is inserted, the force-applying part 1423 gradually descends and resets, and at the same time, the roller surface of the sliding wheel slides from the second force-bearing surface into the first force-bearing surface, so that the lead movable clamp 1324 approaches the lead fixed clamp 1325 to clamp the conductive lead 12.

[0075] Specifically, the movable lead clamp 1324 is also provided with a reset elastic element fixed to one end of the clamp guide rod 1322 (that is, the clamp guide rod 1322 is fixedly connected to the clamp mounting base 1321 or the movable lead clamp 1324 through the reset elastic element), so as to ensure that after the force application part 1423 descends and resets, the movable lead clamp 1324 is reset to a position that can cooperate with the fixed lead clamp 1325 to clamp the conductive lead 12.

[0076] In another embodiment, the force-applying part 1423 is a wedge-shaped force-applying surface, and the force-receiving part 13241 is a wedge-shaped force-receiving surface. The wedge-shaped force-applying surface and the wedge-shaped force-receiving surface are parallel to each other and inclined to the force-applying direction of the force-applying part 1423. This allows the force-receiving surface to be forced upwards when the force-applying surface is forced upwards, causing the lead wire movable clamp 1324 to move backwards. The specific principle is the same as above and will not be repeated here. Of course, this solution is not limited to the above two arrangements of the force-applying part 1423 and the force-receiving part 13241. The force-applying direction of the force-applying part 1423 can also be aligned with the direction in which the lead wire movable clamp 1324 moves away from the lead wire fixed clamp 1325. As long as the technical solution that enables the force-applying part 1423 to move the lead wire movable clamp 1324 away from the lead wire fixed clamp 1325 can be considered a simple variation and transformation of this solution.

[0077] The drive unit welding mechanism 150 and the PCBA welding mechanism 230 have the same structure. See also Figure 16-20 The structural diagram is illustrated using the drive unit welding mechanism 150 as an example. The drive unit welding mechanism 150 includes a welding bracket 1501, a positive electrode lead welding unit 1502, and a negative electrode lead welding unit 1503. The positive electrode lead welding unit 1502 and the negative electrode lead welding unit 1503 are respectively connected to the welding bracket 1501. Both the positive electrode lead welding unit 1502 and the negative electrode lead welding unit 1503 include a welding lifting assembly 151, a solder feeding assembly 152, a laser assembly 153, and a welding exhaust gas extraction assembly 154. The welding lifting assembly 151 is fixed to the welding bracket 1501, and the solder feeding assembly 154... Component 152 and laser component 153 are connected to the output end of welding lifting component 151. Welding exhaust gas absorption component 154 is connected to the output end of welding bracket 1501 or welding lifting component 151. The solder bar output end of solder feeding component 152 and the laser emission port of laser component 153 both extend toward the drive unit 11 to be welded on the external drive unit carrier. Welding exhaust gas absorption component 154 is located on the side of the solder bar output end of solder feeding component 152 and the laser emission port of laser component 153, and is used to absorb the exhaust gas generated by the solder bar under the action of laser.

[0078] The welding mechanism 150 of this solution uses a positive lead welding unit 1502 and a negative lead welding unit 1503 mounted on a welding bracket 1501 to simultaneously weld the positive and negative conductive leads 12. The positive and negative lead welding units 1502 and 1503 have identical structures, ensuring welding consistency and improving welding efficiency. Both the positive and negative lead welding units 1502 and 1503 include a solder feeding assembly 152 and a laser assembly 153, enabling simultaneous solder feeding and laser welding. Simultaneously, a welding exhaust assembly 154 removes waste gas generated during welding in real time, preventing environmental pollution. In this solution, the positive lead welding unit 1502 and the negative lead welding unit 1503 operate synchronously, integrating three cooperating working mechanisms for solder feeding, welding, and exhaust gas removal, achieving fully automated welding operations. This helps save manpower and improve welding efficiency. Similarly, the PCBA welding mechanism 230 in this solution operates on the same principle.

[0079] See Figure 20 The solder feeding assembly 152 includes a translation adjustment part 1521, a lifting adjustment part 1522, a tilt adjustment part 1523, and a solder bar clamp 1524. The translation adjustment part 1521 is fixed to the output end of the soldering lifting assembly 151, the lifting adjustment part 1522 is fixed to the output end of the translation adjustment part 1521, the tilt adjustment part 1523 is fixed to the output end of the lifting adjustment part 1522, and the solder bar clamp 1524 is fixed to the tilt adjustment part 1523. The laser emission direction of the laser assembly 153 is vertically oriented, and the solder feeding direction of the solder bar clamp 1524 intersects with the laser emission direction of the laser assembly 153. The solder bar clamp 1524 feeds solder onto the conductive lead 12 in a tilted vertical direction, and then the laser assembly 153 emits a laser for soldering. The tilted solder feeding direction can accurately align the corresponding position of the conductive lead 12, ensuring that the fed solder bar does not interfere with the laser assembly 153, thus ensuring that the solder feeding action and the laser emission action are performed simultaneously.

[0080] See Figure 18-19 The solder feeding assembly 152 includes two sets, which are symmetrically arranged on both sides of the laser assembly 153, and the solder bar output ends of the two solder bar clamps 1524 extend toward the drive unit 11 to be soldered. The arrangement of the two sets of solder feeding assemblies 152 can ensure full soldering of the drive unit and the motor 102 of 11 with the conductive lead 12, or the two sets of solder feeding assemblies 152 can work alternately to achieve interval solder feeding.

[0081] In this embodiment, the tilt adjustment part 1523 includes a vertical adjustment member 15231, a tilt adjustment member 15232, and a clamp connector 15233. The vertical adjustment member 15231 has one or two linear lifting adjustment slide holes 152311 extending vertically at its top and an arc-shaped tilt adjustment slide hole 152312 at its bottom. The tilt adjustment member 15232 has a tilt adjustment screw hole 152331 and an oblique lifting adjustment screw hole 152332. The clamp connector 15233 has a linear oblique lifting adjustment slide hole 152333 at its top and a clamp connection hole at its bottom.

[0082] The lifting adjustment slide hole 152311 is slidably connected to the lifting adjustment part 1522 via a screw, and the sliding adjustment direction of the two is linear and parallel to the vertical plane; the tilt adjustment screw hole 152331 is slidably connected to the tilt adjustment slide hole 152312 via a screw, and the sliding adjustment direction of the two is arc-shaped; the oblique lifting adjustment screw hole 152332 is slidably connected to the oblique lifting adjustment slide hole 152333 via a screw, and the sliding adjustment direction of the two is linear and intersects the horizontal and vertical planes; the solder bar clamp 1524 is connected to the clamp connecting hole. It can be understood that the screw passes sequentially through the tilt adjustment screw hole 152331 and the arc-shaped tilt adjustment slide hole 152312, and can slide within the arc-shaped tilt adjustment slide hole 152312, thereby realizing the adjustment of the clamp connecting part 15233 in the rotational direction. Similarly, the screw passes through the inclined lifting adjustment screw hole 152332 and the inclined lifting adjustment slide hole 152333 in sequence, and can be slidably adjusted within the inclined lifting adjustment slide hole 152333, thereby realizing the adjustment of the clamp connector 15233 in the inclined direction, so as to further adjust the position of the solder bar clamp 1524.

[0083] In this embodiment, a temperature sensor 1531 is provided inside the laser assembly 153 to sense the temperature during the welding process. The temperature sensor 1531 is useful for real-time monitoring of the laser welding temperature, preventing the solder bar from failing to melt due to excessively low temperature or the conductive lead 12 from melting due to excessively high temperature.

[0084] In this embodiment, the welding exhaust gas assembly 154 includes a welding exhaust gas pipeline 1541 and a welding exhaust gas hood 1542. One end of the welding exhaust gas pipeline 1541 is connected to an external extraction device, and the other end is connected to the welding exhaust gas hood 1542. The welding exhaust gas hood 1542 is positioned around the solder bar output end of the solder feeding assembly 152 and the side periphery of the laser emission port of the laser assembly 153. The welding exhaust gas hood 1542 is used to enclose the area where exhaust gas is generated, thereby facilitating the complete absorption of exhaust gas by the welding exhaust gas pipeline 1541.

[0085] In this embodiment, both the positive lead welding unit 1502 and the negative lead welding unit 1503 further include a solder breaking component 155, which is fixed to the output end of the welding lifting component 151. The solder breaking component 155 is used to drill holes in the surface of the solder bar before soldering. A flexible tube channel (not shown) is provided between the solder breaking component 155 and the solder bar clamp 1524. After drilling holes in the solder bar, the solder bar is conveyed through the flexible tube into the solder bar clamp 1524, and then the solder bar is delivered to the junction position of the positive and negative conductive leads 12 and the motor 102 by the solder bar clamp 1524. The solder bar is melted by laser heating, so that the positive and negative conductive leads 12 are soldered to the motor 102.

[0086] In this embodiment, both the positive electrode lead welding unit 1502 and the negative electrode lead welding unit 1503 further include a welding translation component 156. The welding translation component 156 is fixed to the output end of the welding lifting component 151, and the solder feeding component 152 and the laser component 153 are both fixed to the output end of the welding translation component 156. The arrangement of the welding translation component 156 facilitates the horizontal translation of the solder feeding component 152.

[0087] See Figure 6 The drive unit unloading and conveying mechanism 160 includes an unloading translation drive assembly, an unloading lifting drive assembly, an unloading rotation drive assembly, an unloading opening and closing drive assembly, and two unloading clamps. The unloading translation drive assembly is located at the unloading station. The unloading lifting drive assembly is fixed to the output end of the unloading translation drive assembly, the unloading rotation drive assembly is fixed to the output end of the unloading lifting drive assembly, the unloading opening and closing drive assembly is fixed to the output end of the unloading rotation drive assembly, and the two unloading clamps are respectively fixed to the two output ends of the unloading opening and closing drive assembly. The unloading translation drive assembly is used to drive the two unloading clamps to transport the clamped drive unit 11 from the drive unit carrier 130 at the unloading station to the drive unit unloading conveying mechanism 170.

[0088] The shaver unloading mechanism 240 includes a shaver unloading and conveying assembly 241, a shaver flipping assembly 242, and a shaver welding unloading and conveying assembly 243. The shaver unloading and conveying assembly 241 is located between the PCBA welding turntable 210 and the shaver flipping assembly 242, and is used to transport the welded shavers into the shaver flipping assembly 242. The output end of the shaver flipping assembly 242 is connected to the shaver welding unloading and conveying assembly 243, and is used to flip the welded shavers to another placement position. The shaver welding unloading assembly is used to output the welded shavers to the next process device. It is understood that the welded bare shaver can be directly handled by a robotic arm; however, to facilitate the next process, the shaver is flipped using the shaver flipping assembly 242 to change the output direction.

[0089] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
