Description

Technical Field

[0001] This invention relates to the field of core wire welding technology, and in particular to a resistance welding-laser welding equipment for core wire welding. Background Technology

[0002] Traditional wire bonding primarily employs resistance welding technology. However, resistance welding has several significant drawbacks, such as a large heat-affected zone that easily leads to material deformation and oxidation, especially noticeable in thin materials or precision components. Furthermore, electrode wear is a major issue, requiring frequent electrode replacements, which are subject to significant parameter fluctuations, potentially impacting weld quality. Additionally, existing laser welding equipment, due to its small laser spot size, is prone to welding defects such as incomplete welds and weld depressions.

[0003] To address these issues, the industry has been exploring new welding technologies, among which the combination of resistance welding and laser welding has attracted widespread attention. This combination can fully leverage the advantages of both technologies, improving welding efficiency while reducing weld spalling and burn-through, thereby increasing product yield. However, how to effectively combine resistance welding and laser welding while ensuring both improved welding quality and efficiency remains a pressing technical challenge.

[0004] After long-term research on core wire welding, the inventors discovered that in addition to improving the welding quality of core wires by performing resistance welding followed by laser welding, the position of the core wire and the pad is still very important during welding. Furthermore, the inventors found that because the core wire is a flexible component, although manual or mechanical shaping can align it with the welding area of ​​the pad, the core wire often requires 2-3 stations and a transmission distance of 4-5 meters during its movement through the welding station. Due to the bifurcation of the two core wires and the flexibility of the core wire, some core wires will deviate from the pad after the product is delivered to the welding station, thus affecting the welding quality between the core wire and the pad. Moreover, during the welding process, the two core wires are welded separately. When welding one core wire, after the solder melts, the other core wire may move to some extent, further affecting the welding quality between the core wire and the pad. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a resistance welding-laser welding equipment for core wire welding.

[0006] The objective of this invention is achieved through the following technical solution: a resistance welding-laser welding equipment for core wire welding, comprising a resistance welding module, a laser welding module, and a controller for controlling the operation of the resistance welding module and the laser welding module. A product conveyor line transports products along the X direction. With the transport direction of the product conveyor line as the rear, the resistance welding module is located in front of the laser welding module.

[0010] A resistance welding-laser welding equipment for core wire welding also includes a core wire shaping mechanism. The core wire shaping mechanism is located in front of the resistance welding module. The core wire shaping mechanism includes a lifting frame, on which a double-headed clamping cylinder is installed. Movable frames are installed on both movable ends of the double-headed clamping cylinder. At least one clamping tooth is provided at the bottom of the movable frame. On the X-axis projection plane, the clamping teeth of the two movable frames have an overlapping part, and the clamping teeth on the two movable frames are staggered in the X-axis. In the X-axis, every two clamping teeth constitute a clamping part. Several central positioning elements are also provided at the bottom of the lifting frame. The central positioning elements are located between two clamping teeth of the clamping part. On the Z-axis projection plane, the bottom of the central positioning elements is located below the clamping teeth.

[0011] Optionally, the top of the lifting frame has a groove, a double-headed clamping cylinder is installed in the groove, and limit adjustment rulers that limit the X-axis movement distance of the movable frame are installed on the two side walls of the groove.

[0012] Optionally, buffer springs are also installed on both sides of the tank, with the other end of the buffer spring abutting against the movable frame.

[0013] Optionally, in the X direction, guide rails are provided on both sides of the lifting frame, and sliding grooves are provided on the movable frame to slide with the guide rails.

[0014] Optionally, the movable frame includes a sliding seat, a clamping seat, and a clamping frame. The sliding seat is slidably mounted on the guide rail via a sliding groove. The clamping seat is detachably mounted on the sliding seat and is connected to the movable end of the corresponding clamping cylinder. The clamping frame is detachably mounted on the clamping seat, and the clamping teeth are located at the bottom of the clamping frame. The buffer spring abuts against the clamping seat.

[0015] Optionally, the laser welding module includes a frame, on which an X-axis linear module is mounted, an X-axis movable seat is mounted on the X-axis linear module, a Z-axis linear module is mounted on the X-axis movable seat, a connecting frame is mounted on the Z-axis movable seat, a Y-axis linear module is mounted on the connecting frame, the Y-axis linear module is located to one side of the Z-axis linear module, a Y-axis movable seat is mounted on the Y-axis linear module, a second CCD module is mounted on the Y-axis movable seat, a laser head is also mounted on the Z-axis movable seat, and a laser optical path assembly is also mounted on the frame.

[0016] Optionally, the laser optical path assembly includes a laser generator, a galvanometer, a field mirror, and several sets of reflectors. The laser generator is mounted on a frame. The laser emitted by the laser optical path assembly is transmitted to the galvanometer through several sets of reflectors. The galvanometer transmits the laser to the field mirror, and the field mirror transmits the laser to the laser head.

[0017] The present invention has the following advantages:

[0018] 1. The resistance welding-laser welding equipment of the present invention performs secondary lap welding through laser welding on the basis of resistance welding, thereby forming a raised boss at the weld point, so that the core wire and the welding pad are fused together, thereby reducing the problems of weld point detachment and weld burn-through, improving the reliability and stability of welding, ensuring the overall quality of core wire welding, thus giving full play to the advantages of resistance welding and laser welding, effectively solving the shortcomings of traditional resistance welding technology such as large heat-affected zone and prominent electrode wear, and significantly improving welding accuracy and product quality;

[0019] 2. The resistance welding-laser welding equipment of the present invention is equipped with a core wire shaping mechanism. Positioned by a central positioning component, two corresponding core wires can be separated. Then, by pressing and clamping by a clamping part, the core wire can be brought into contact with the solder pad and returned to the welding area of ​​the solder pad, thus achieving core wire shaping. This provides a shaping basis for welding the core wire and the solder pad, and eliminates the need for manual shaping, reducing production costs. Furthermore, during the shaping process, the core wire makes surface contact with the central positioning component and clamping teeth, avoiding damage to the core wire plating. This design prevents damage and ensures the reliability of core wire shaping. By pressing down on the core wire with the clamping part, the core wire tends to be straight in the Y-direction projection, thus allowing the curved core wire to fit against the pad. The clamping part also clamps the core wire, moving it to the soldering area of ​​the pad. Furthermore, the distance between the clamping teeth and the center positioning part can be adjusted according to the size of the core wire and the position of the pad using the limit adjustment ruler. This ensures that the core wire tends to be straight after being clamped, further guaranteeing the soldering quality between the core wire and the pad.

[0020] 3. The resistance welding-laser welding equipment of the present invention is equipped with a core wire welding dynamic correction device. The CCD module captures the image of the product welding area to determine the offset between the core wire and the pad. The core wire is moved by a fork to adjust its position relative to the pad, thereby ensuring that the core wire is within the welding area of ​​the pad, thus improving welding quality and yield. By individually controlling the micro geared motor, the core wire on each pad can be adjusted independently, ensuring the reliability of the core wire and pad position adjustment.

[0045] like Figure 1As shown, a resistance welding-laser welding equipment for core wire welding includes a resistance welding module 200, a laser welding module 100, and a controller for controlling the operation of the resistance welding module 200 and the laser welding module 100. A product conveyor line 229 conveys products along the X direction. With the conveying direction of the product conveyor line 229 as the rear direction, the resistance welding module 200 is located in front of the laser welding module 100. The resistance welding module 200 includes a first CCD module 225, a resistance welding assembly 226, and a core wire dynamic correction device. The first CCD module 225 and the resistance welding assembly 226 are arranged on the same side, and the resistance welding assembly... Component 226 is located on one side of the product conveyor line 229, and the core wire dynamic correction device is located on the other side of the product conveyor line 229. Therefore, when the core wire is welded, it is first welded by the resistance welding module 200 and then by the laser welding module 100. This fully utilizes the advantages of resistance welding and laser welding, effectively solving the shortcomings of traditional resistance welding technology, such as large heat-affected zone and prominent electrode wear. It significantly improves welding accuracy and product quality. Moreover, the laser welding technology reduces the problems of weld point detachment and weld penetration, improves the reliability and stability of welding, and ensures the overall quality of core wire welding.

[0046] In this embodiment, as Figure 12 and Figure 13 As shown, the laser welding module 100 includes a frame 101. An X-axis linear module 120 is mounted on a mounting platform 102 of the frame 101. An X-axis moving seat 121 is mounted on the X-axis linear module 120. When the X-axis linear module 120 is operational, it can drive the X-axis moving seat 121 to move along the X-axis. A Z-axis linear module 140 is mounted on the X-axis moving seat 121. A Z-axis moving seat 141 is mounted on the Z-axis linear module 140. When the Z-axis linear module 140 is operational, it can drive the Z-axis moving seat 141 to move along the Z-axis. Figure 15 and Figure 16As shown, a connecting frame 131 is provided on the Z-axis moving base 141, and a Y-axis linear module 130 is mounted on the connecting frame 131. The Y-axis linear module 130 is located on one side of the Z-axis linear module 140, and a Y-axis moving base 151 is mounted on the Y-axis linear module 130. When the Y-axis linear module 130 is working, it can drive the Y-axis moving base 151 to move along the Y direction. Preferably, the X-axis linear module 120, the Y-axis linear module 130, and the Z-axis linear module 140 are all linear motor modules. That is to say, the X-axis linear module 120, the Y-axis linear module 130, and the Z-axis linear module 140 are all linear motor modules. Both module 130 and Z-axis linear module 140 are commercially available products. The use of linear motor modules to drive the moving base is existing technology and will not be elaborated upon. However, by using linear motor modules, the movement accuracy can reach sub-micron levels or even higher, thus ensuring the accuracy of the moving base's movement. In this embodiment, a second CCD module 157 is installed on the Y-axis moving base 151, a laser head 119 is installed on the Z-axis moving base 141, and a laser optical path assembly 110 is installed on the frame 101. The laser output from the laser optical path assembly 110... On the laser head 119, the second CCD module 157 is located in front of the laser head 119. During use, when the product moves under the second CCD module 157, the second CCD module 157 captures the image to obtain the laser welding area and sends it to the control unit. The controller that controls the laser welding module 100 is the control unit. After processing the image, the control unit displays the parameters through the display unit 162. At the same time, the operator can also adjust the laser welding parameters according to the input unit 164 to ensure the quality of laser welding. The image capture, image processing, data display, and parameter modification by the second CCD module 157 are all existing technologies and will not be described in detail. After the second CCD module 157 captures the image, it can obtain the laser welding area, which facilitates the laser head 119 to weld it. After the product conveyor moves the product to the laser welding station, the X-axis moving seat 121 moves, thereby driving the laser head 119 to move along the X-axis, so that multiple laser welding points on the product can be welded.

[0047] In this embodiment, as Figure 12 and Figure 13As shown, a first bracket 103 is also provided at the bottom of the Z-axis moving base 141. A visual positioning component 104 for monitoring the laser welding area is installed on the first bracket 103. Preferably, the visual positioning component 104 is a commercially available high-speed camera with a pixel accuracy of 0.003mm / Pixel. The high-speed camera can monitor the laser welding situation in real time and transmit the welding situation to the control unit. The control unit then controls the laser generator 111 to adjust the corresponding parameters, thereby ensuring the quality of laser welding and avoiding excessive power that could weld through the welding area. The products conveyed on the product conveyor line have already undergone one resistance welding process, therefore, their welding points are relatively... The process involves fixing the wire in place and then performing a secondary lap welding using laser welding on top of resistance welding. This creates raised bosses at the weld points, causing the core wire and the pad to fuse together. This reduces the risk of solder joint detachment and burn-through, improving the reliability and stability of the welding process and ensuring the overall quality of the welded product. This fully leverages the advantages of both resistance welding and laser welding, effectively addressing the shortcomings of traditional resistance welding techniques, such as large heat-affected zones and significant electrode wear. It significantly improves welding precision and product quality. Furthermore, after laser welding, the weld points can be inspected using a high-speed camera to detect any instances of incomplete weld joints, eliminating the need for dedicated incomplete weld joint detection equipment and reducing equipment investment costs.

[0048] In this embodiment, as Figure 12 and Figure 13 As shown, a second bracket 105 is installed on the first bracket 103, and a cleaning component 106 for cleaning the laser welding area is also installed on the second bracket 105. Furthermore, the cleaning component 106 adopts a commercially available plasma blowing device or a commercially available vacuum suction device to ensure the cleanliness of the laser welding area and thus ensure the quality of laser welding.

[0049] In this embodiment, the second CCD module 157, the visual positioning component 104, the cleaning component 106, the X-axis linear module 120, the Y-axis linear module 130, and the Z-axis linear module 140 are all connected to the control unit via wires. The second CCD module 157 is a commercially available product. The second CCD module 157 transmits image data to the control unit, and the visual positioning component 104 transmits real-time monitoring data to the control unit. The control unit is prior art, and its control logic and image analysis technology are also prior art. Preferably, the control unit adopts bus control and has remote maintenance functions. Equipment electrical control faults can be handled remotely through a program. The control unit supports data extraction and storage of defective images. The industrial computer hard drive is larger than 1TB, and the data storage time is greater than 180 days. The control unit also includes a remote monitoring module, which can monitor the welding process in real time and record data.

[0050] In this embodiment, as Figure 14As shown, a fixed frame 152 is mounted on the Y-axis movable seat 151, and a slider 153 is mounted on the fixed frame 152. The slider 153 and the fixed frame 152 are locked together by a locking assembly. A Z-axis position adjustment ruler 158 is also mounted on the fixed frame 152. A second CCD module 157 is mounted on the slider 153. A light source 159 is also mounted on the Y-axis movable seat 151. The light source 159 is located below the second CCD module 157. Preferably, a guide rail is provided on the fixed frame 152, and a groove is provided on the slider 153 to slide with the guide rail. Further, the groove can be a dovetail groove to prevent the slider 153 from derailing. In this embodiment, the locking assembly includes a locking plate 154 and a locking screw 156. The locking plate 154 is mounted on one side of the fixed plate, and a Z-axis extending groove is provided on the locking plate 154. The adjustment hole 155 and the slider 153 are provided with screw holes. The locking screw 156 passes through the adjustment hole 155 and locks with the screw hole. The head of the locking screw 156 presses tightly against the locking plate 154. The Z-axis position adjustment ruler 158 is a micrometer. The top of the fixing bracket 152 is provided with a mounting bracket. The micrometer is detachably mounted on the mounting bracket. In use, the locking screw 156 can be loosened first. Then, according to the size requirements, the micrometer is adjusted to the specified position. Then, the slider 153 is pushed to move so that the top of the slider 153 abuts against the micrometer. Finally, the locking screw 156 is tightened. Under normal circumstances, the Z-axis position of the second CCD module 157, the Y-axis position of the Y-axis moving seat 151, and the Z-axis position of the Z-axis moving seat 141 are adjusted during the debugging stage. During the use of the equipment, their positions do not move.

[0051] In this embodiment, as Figure 17As shown, the laser optical path assembly 110 includes a laser generator 111, a galvanometer 117, a field mirror 118, and several sets of reflectors. The laser generator 111 is mounted on a rack 101. The laser emitted by the laser optical path assembly 110 is transmitted to the galvanometer 117 via several sets of reflectors. The galvanometer 117 transmits the laser to the field mirror 118, and the field mirror 118 transmits the laser to the laser head 119. Furthermore, the reflector sets include a first reflector set 112, a second reflector set 114, a third reflector set 115, and a fourth reflector set 116. The first reflector set 112, the second reflector set 114, and the third reflector set 115 are all mounted on the rack 101, and the first reflector set 112 and the second reflector set 116 are connected to the second reflector set 117. A beam expander 113 is also installed between groups 114. The fourth reflector group 116 is installed on the Z-axis moving seat 141. The galvanometer 117 is connected to the fourth reflector group 116. The field mirror 118 is connected to the bottom of the galvanometer 117. The laser head 119 is installed on the field mirror 118. Therefore, the laser emitted by the laser generator 111 enters the galvanometer 117 after multiple refractions. Then, the galvanometer 117 adjusts the laser target position according to the welding requirements, which facilitates the laser head 119 to perform welding positioning. The first reflector group 112, the second reflector group 114, the third reflector group 115, the fourth reflector group 116 and the beam expander 113 are all covered by protective covers to ensure the reliability of laser transmission.

[0052] In this embodiment, as Figure 1As shown, the resistance welding module 200 includes a first CCD module 225, a resistance welding assembly 226, a core wire shaping mechanism 220, and a core wire dynamic correction device. The first CCD module 225 and the resistance welding assembly 226 are arranged on the same side, with the resistance welding assembly 226 located on one side of the product conveyor line 229 and the core wire dynamic correction device located on the other side of the product conveyor line 229. Before resistance welding, the core wire is shaped, and then welding is performed simultaneously with the core wire dynamic correction device. Specifically, the resistance welding module... 200 also includes a first X-axis moving module 221 and a Y-axis moving module 222. The first X-axis moving module 221 drives the Y-axis moving module 222 to move along the X direction. A mounting plate extending in the Z direction is provided on the sliding plate of the Y-axis moving module 222. A first Z-axis moving module 223, a second Z-axis moving module 224, and a first CCD module 225 are mounted on the mounting plate. The first CCD module 225 is located between the first Z-axis moving module 223 and the second Z-axis moving module 224. The second Z-axis moving module 223... Resistance welding assembly 226 is mounted on the sliding plate of the first Z-axis moving module 223, and core wire shaping mechanism 220 is mounted on the sliding plate of the first Z-axis moving module 223. In this embodiment, the first X-axis moving module 221, Y-axis moving module 222, first Z-axis moving module 223, and second Z-axis moving module 224 are all prior art. Preferably, the first X-axis moving module 221, Y-axis moving module 222, first Z-axis moving module 223, and second Z-axis moving module 224 all adopt linear motor modules. The module's movement accuracy can reach the sub-micron level or even higher, thus ensuring the accuracy of each movement module. Moreover, through the first X-axis movement module 221 and the Y-axis movement module 222, the core wire shaping mechanism 220 and the resistance welding assembly 226 can move in a plane within a specified range. Through the first Z-axis movement module 223, the core wire shaping mechanism 220 can move in the Z direction. Through the second Z-axis movement module 224, the resistance welding assembly 226 can move in the Z direction.

[0053] In this embodiment, the core wire shaping mechanism 220 includes a lifting frame 201, which is detachably mounted on the sliding plate of the first Z-axis moving module 223 by screws. A double-headed clamping cylinder 202 is mounted on the lifting frame 201, and movable frames are mounted on both movable ends of the double-headed clamping cylinder 202. At least one clamping tooth is provided at the bottom of the movable frame. On the X-axis projection plane, the clamping teeth of the two movable frames have an overlapping portion. Preferably, on the X-axis projection plane, the clamping teeth of the two movable frames completely overlap, while the clamping teeth on the two movable frames are staggered in the X-axis direction. Figure 3 , Figure 4 and Figure 5 As shown, in the X direction, every two gripping teeth form a clamping part, that is to say, as Figure 5As shown, the first clamping tooth 207 on one movable frame and the corresponding second clamping tooth 209 on another movable frame constitute a clamping part. The bottom of the lifting frame 201 is also provided with several center positioning members 208, which are located between two clamping teeth of the clamping part. On the X-axis projection plane, the bottom of the center positioning member 208 is located below the clamping teeth. In this embodiment, as shown... Figure 3 and Figure 4As shown, the movable frame moves with the two movable ends of the double-headed clamping cylinder 202. Furthermore, when the two movable ends of the double-headed clamping cylinder 202 approach each other, the two clamping teeth on the clamping part move away from each other, thus disengaging the core wire. Conversely, when the two movable ends of the double-headed clamping cylinder 202 move away from each other, the two clamping teeth on the clamping part approach each other, thus clamping the core wire and placing it in the soldering area of ​​the solder pad. In this embodiment, the center positioning member 208 and the clamping teeth of the movable frame are equally spaced in the X-direction. For example, the bottom of the movable frame has eight clamping teeth, two movable frames have sixteen clamping teeth, and the clamping part has eight. The center positioning member 208 at the bottom of the lifting frame 201 also has eight teeth, thus enabling simultaneous... The system simultaneously shapes eight sets of core wires. During use, appropriate clamping teeth are added to the bottom of the movable frame based on actual conditions. To ensure overlap of the clamping teeth in the X-axis direction, an inclined surface is provided at the bottom of the movable frame, forming a V-shape on the X-axis projection plane. During use, the lifting frame 201 descends, and the center positioning element 208 is inserted between the two core wires. The solder pad also has a notch through which the center positioning element 208 passes. As the center positioning element 208 is inserted, the two core wires open and move towards the solder pad. At this time, the double-headed clamping cylinder 202 is in the open state. During the insertion of the center positioning element 208, the two core wires are further... The bottom surface of the clamping part presses against the core wire in the Z direction, making the bottom surface of the core wire fit against the pad. Simultaneously, it presses down on any arched core wire, making its projection in the Y direction more linear, thus facilitating the fit between the chip and the bottom surface of the chip against the pad. Then, the lifting frame 201 rises a certain distance. At this point, the central positioning element 208 remains within the gap in the pad, thus restricting the core wire from moving towards the gap. Then, the two movable ends of the double-headed clamping cylinder 202 retract, causing the clamping part to open. The lifting frame 201 then descends. When the bottom of the clamping part is flush with the top surface of the pad or has a gap of no more than 0.05mm, the lifting frame 201 stops descending. Then, the double-headed clamping cylinder 202... The two movable ends open, causing the clamping part to contract. The two clamping teeth on the clamping part then press the core wire that deviates from the pad towards the center positioning member 208, thereby bringing the core wire that deviates from the pad back into the soldering area of ​​the pad. Since the bottom of the clamping part is flush with the top surface of the pad or has a gap of no more than 0.05mm with the top surface of the pad, the clamping part is prevented from being interfered with by the pad when clamping the core wire, and collision between the clamping part and the pad is also prevented, which would affect the product quality. Preferably, the two clamping teeth on the clamping part are symmetrical about the corresponding center positioning member 208. Therefore, the two clamping teeth on the clamping part move the same distance relative to the corresponding center positioning member 208, thereby making the core wire arrangement more neat after shaping.

[0054] In this embodiment, as Figure 5As shown, the bottom of the center positioning member 208 is provided with a wedge head 206. The wedge head 206 facilitates the insertion of the center positioning member 208 between the two core wires. Moreover, the wedge head 206 is thin at the bottom and thick at the top. During the insertion of the wedge head 206, the wedge head 206 can squeeze the core wire to both sides without damaging the surface of the core wire. At the top of the wedge head 206, there is also a rectangular structure. The width of the rectangular structure is the same as the width of the notch on the pad. When the clamping part clamps the core wire, part of the rectangular structure is inserted into the notch, thereby ensuring that the core wire can return to the soldering area of ​​the pad.

[0055] In this embodiment, as Figure 3 and Figure 4 As shown, the top of the lifting frame 201 has a groove, and the double-headed clamping cylinder 202 is installed in the groove. Limiting adjustment rulers 203 that limit the X-axis movement distance of the movable frame are installed on the two side walls of the groove. Preferably, the limiting adjustment rulers 203 are micro rulers. The opening distance of the movable frame can be adjusted by the two micro rulers, thereby adjusting the clamping distance of the two clamping teeth of the clamping part. This ensures the reliability of the clamping part in clamping and shaping the core wire, and at the same time avoids excessive compression that could damage the surface of the core wire. Moreover, the limiting adjustment rulers 203 can adjust the distance between the clamping teeth and the center positioning part 208 according to the size of the core wire and the position of the solder pad. This makes the core wire tend to be straight after being clamped, thereby further ensuring the welding quality of the core wire and the solder pad.

[0056] In this embodiment, as Figure 3 and Figure 4 As shown, buffer springs 214 are also installed on the two side walls of the tank. The other end of the buffer spring 214 abuts against the movable frame. Furthermore, spring mounting holes are opened on the inner side of the two side walls of the tank, and spring mounting holes are also opened on the outer side of the movable frame. The two ends of the buffer spring 214 are installed in the corresponding spring mounting holes. When the two movable ends of the double-headed clamping cylinder 202 move away from each other, the buffer spring 214 will be compressed during the movement of the movable frame, thereby hindering the movement of the movable frame. This buffers the movement of the movable frame and prevents the movable frame from impacting the micrometer instantly, thus affecting the accuracy of the micrometer. Moreover, when the clamping part clamps the core wire, the clamping part can gradually squeeze the core wire, thus buffering the clamping of the core wire and preventing damage to the core wire, ensuring the reliability of the core wire shaping.

[0057] In this embodiment, as Figure 4As shown, in the X direction, guide rails 212 are provided on both sides of the lifting frame 201. The movable frame is provided with sliding grooves that slide with the guide rails 212. Through the cooperation of the sliding grooves with the guide rails 212, the accuracy of the movement of the movable frame can be guaranteed. Furthermore, the movable frame includes a sliding seat 213, a clamping seat 204, and a clamping frame 205. The sliding seat 213 is slidably mounted on the guide rails 212 through the sliding grooves. The clamping seat 204 is detachably mounted on the sliding seat 213 and is connected to the movable end of the corresponding clamping cylinder. The clamping frame 205 is detachably mounted on the clamping seat 204, and the clamping teeth are set at the bottom of the clamping frame 205. The buffer spring 214 abuts against the clamping seat 204, so that the movable frame can be disassembled. When the clamping teeth are worn, only the clamping frame 205 needs to be replaced. This also makes the entire movable frame more convenient to process.

[0058] In this embodiment, as Figure 2 and Figure 3 As shown, the bottom of the lifting frame 201 has a connecting end 211, and a connector 210 is detachably installed on the connecting end 211. A center positioning part 208 is provided at the bottom of the connector 210. Matching steps are provided on both the connecting end 211 and the connector 210, and the connecting end 211 and the connector 210 are locked together by screws.

[0059] In this embodiment, the working process of the core wire shaping mechanism 220 is as follows: After the product conveyor line moves to the shaping station through the product clamping fixture, the first X-axis moving module 221 and the Y-axis moving module 222 work to move the first CCD module 225 above the shaping station. After the first CCD module 225 takes a picture, it obtains the relative position of the core wire and the pad, and transmits the data to the controller. In this embodiment, the controller works in conjunction with the first X-axis moving module 221, the Y-axis moving module 222, and the first Z-axis moving module 223. The second Z-axis moving module 224, the resistance welding assembly 226, and the double-headed clamping cylinder 202 are all connected to the controller. The controller's control of the first X-axis moving module 221, the Y-axis moving module 222, the first Z-axis moving module 223, the second Z-axis moving module 224, the resistance welding assembly 226, and the double-headed clamping cylinder 202 is prior art; therefore, its specific control methods will not be elaborated upon. The controller, based on received data, then controls the first X-axis moving module 221 and the Y-axis moving module 222 to... The center positioning component 208 is aligned with the notch on the corresponding pad. Then, the first Z-axis moving module 223 operates, causing the lifting frame 201 to descend. The wedge head 206 is inserted between the two corresponding core wires and into the notch on the pad. As the wedge head 206 is inserted, the two core wires open and move towards the pad. At this time, the double-headed clamping cylinder 202 is in the open state. During the insertion of the center positioning component 208, the bottom surface of the clamping part presses against the core wire in the Z direction, making the bottom surface of the core wire fit against the pad. Simultaneously, it can also press down on the arched core wire, making the core wire's projection in the Y direction tend to be straight, thus facilitating the chip's contact with the bottom surface and the pad. Then, the lifting frame 201 rises a certain distance, and the clamping part disengages from the core wire. At this time, the wedge head 206 is still within the gap of the pad, thus restricting the core wire from moving towards the gap of the pad. Then, the two movable ends of the double-headed clamping cylinder 202 retract, thereby opening the clamping part. Then, the lifting frame 201 descends, and when the bottom of the clamping part is flush with the top surface of the pad or at a distance of no more than 0.When the gap is 0.5mm, the lifting frame 201 stops descending. Then, the two movable ends of the double-headed clamping cylinder 202 open, causing the clamping part to retract. The two clamping teeth on the clamping part then press the core wire that deviates from the solder pad towards the center positioning member 208. During the pressing process, due to the presence of the buffer spring 214, the clamping part and the core wire are subjected to flexible pressing, thus avoiding damage to the core wire. After pressing, the core wire that deviates from the solder pad is pressed into the soldering area of ​​the solder pad. Then, the movable end of the double-headed clamping cylinder 202 retracts, causing the clamping part to unfold. Then, the first Z-axis moving module 223 works, causing the lifting frame 201 to rise, causing the clamping part and the center positioning member 208 to disengage from the solder pad and the core wire. The first Z-axis moving module 223 and the double-headed clamping cylinder 202 reset. The product conveyor line transports the shaped product to the next station and the unshaped product to the shaping station, and then shapes the next product.

[0060] In this embodiment, as Figure 6 As shown, the core wire dynamic correction device includes a second X-axis moving module 227 and a third Z-axis moving module 228. The third Z-axis moving module 228 is mounted on the second X-axis moving module 227. A lifting body 231 is detachably mounted on the sliding plate of the third Z-axis moving module 228. Figure 7 and Figure 9 As shown, the lifting body 231 is equipped with multiple miniature geared motors 232 extending along the Y direction, and the multiple miniature geared motors 232 are spaced apart in the X direction, as shown. Figure 7 and Figure 8As shown, a swing arm 236 is installed on the power output end of the micro geared motor 232, and the axis of the micro geared motor 232 is perpendicular to the plane in which the swing arm 236 swings. A clearance groove 235 is provided on the lifting body 231. The bottom of the swing arm 236 passes through the clearance groove 235, and the top of the swing arm 236 can swing within the clearance groove 235. A fork 237 for moving the core wire cable is provided at the bottom of the swing arm 236. The micro geared motor 232, the first CCD module 225, the resistance welding assembly 226, the second X-axis moving module 227, and the third Z-axis moving module 228 are all connected to the controller. The controller controls multiple micro geared motors 232, the first CCD module 225, the resistance welding assembly 226, the second X-axis moving module 227, and the third Z-axis moving module 228 to work independently. When the core wire cable is corrected by the correction mechanism 230, the first CCD module 225 captures an image of the product welding area. The system captures an image of the product's welding area and transmits it to the controller. The controller processes the image to obtain the position of the core wire cable. Based on this position, the controller controls the correction mechanism 230 to move in the X direction. Once in position, the third Z-axis movement module 228 controls the lifting body 231 to descend, thus positioning the head of the core wire cable within the corresponding fork 237. Then, the first CCD module 225 captures an image of the product's welding area again and transmits it to the controller. The controller processes the image to obtain the offset between the core wire and the corresponding pad. Based on this offset, the controller controls multiple micro-gear motors 232 to work independently. The micro-gear motors 232 control the swing arm 236's arc based on the received offset information, thereby moving the core wire cable relative to the pad, ensuring the core wire is positioned on the corresponding pad. In this embodiment, the product has eight welding points and eight core wire cables. Therefore, as... Figure 9 As shown, the miniature geared motor 232 also has eight core wires. After manual or mechanical shaping, the core wires are flexible and have a certain degree of flexibility. Although manual or mechanical shaping can shape the core wires to the soldering area of ​​the pads, during the movement of the core wires at the workstation, due to the forking of the two core wires on the cable and the flexibility of the core wires, some core wires will deviate from the pads when the product is delivered to the soldering station. The fork 237 is used to move the core wire cable so that the core wires are positioned on the pads. Then, the welding assembly welds the core wires to the pads, thereby ensuring the welding quality of the core wires and the pads and improving the product yield. Moreover, the cable has two core wires. When the resistance welding assembly 226 is welding, the two core wires are welded separately. When welding one core wire, after the solder melts, the other core wire may move to a certain extent. The fork 237 can move the weaker core wire to the soldering area of ​​the pads, thereby ensuring the welding quality.

[0061] In this embodiment, as Figure 10 and Figure 11 As shown, the shift fork 237 has a receiving groove 238 for accommodating the core wire cable. When the shift fork 237 moves downward, it can accommodate the core wire cable in the receiving groove 238. Furthermore, the depth of the receiving groove 238 is greater than the height of the core wire cable, and the width of the receiving groove 238 is slightly greater than the width of the core wire cable. In order to facilitate the core wire cable entering the receiving groove 238, the opening of the receiving groove 238 is turned outward to form an open groove 239. Therefore, the cross-section of the open groove 239 is V-shaped. When the shift fork 237 moves downward, the core wire cable first enters the open groove 239, and then enters the receiving groove 238 under the action of the open groove 239. When the micro geared motor 232 drives the swing arm 236 to swing, the receiving groove 238 can drive the head of the core wire cable to move, thereby causing the core wire to move relative to the solder pad, so that the core wire is located in the soldering area of ​​the solder pad.

[0062] In this embodiment, as Figure 8 As shown, the lifting body 231 has a motor mounting hole, and the micro geared motor 232 is installed in the motor mounting hole. In this embodiment, the micro geared motor 232 is a commercially available product. Due to the small size of the product, the installation space for the micro geared motor 232 is small. Therefore, the micro geared motor 232 and the motor mounting hole can be connected by adhesive or by welding to ensure the stability of the installation of the micro geared motor 232 and the lifting body 231.

[0063] In this embodiment, as Figure 8 As shown, the lifting body 231 is also provided with a bearing mounting hole 234. The bearing mounting hole 234 is coaxially arranged with the corresponding motor mounting hole. The bearing mounting hole 234 is located on one side of the clearance groove 235, and the motor mounting hole is located on the other side of the clearance groove 235. A micro bearing 233 is installed at the end of the power output end of the micro gear motor 232. The micro bearing 233 is located in the bearing mounting hole 234. In this embodiment, the micro bearing 233 is a commercially available product, and the bearing mounting hole 234 is a stepped through hole. The micro bearing 233 is installed in the large hole of the stepped through hole, and the micro bearing 233 abuts against the stepped surface of the stepped through hole. Furthermore, the micro gear motor 232 is provided with a flat surface, and the shaft hole at the top of the swing arm 236 has a plane that fits with the flat surface. Therefore, when the micro gear motor 232 rotates, the swing arm 236 can rotate with the power output end of the micro gear motor 232.

[0064] In this embodiment, the spacing between multiple pads on the product is the same, therefore, as Figure 9 As shown, multiple miniature geared motors 232 are distributed at equal intervals in the X direction.

[0065] The core wire welding device includes the following steps during welding:

[0066] S1: In one image capture, the product conveyor line 229 moves the shaped product to the welding station, the first CCD module 225 moves above the welding station, the first CCD module 225 captures the image of the product welding area and transmits the captured image to the controller, the controller processes the image to obtain the position of the core wire cable.

[0067] S2: Core wire and cable clamping. The controller controls the correction mechanism 230 to move in the X direction according to the position of the core wire and cable. After it moves into place, the third Z-axis moving module 228 controls the lifting body 231 to descend, so that the head of the core wire and cable is located in the shift fork 237.

[0068] S3: Secondary image capture. The first CCD module 225 captures the image of the product welding area again and transmits the captured image to the controller. The controller processes the image to obtain the offset between the same side core wire and the corresponding pad.

[0069] S4: With each cable movement, based on the offset between the core wire on the same side and the corresponding pad, the controller controls multiple micro geared motors 232 to work independently. The micro geared motors 232 control the swinging arc of the swing arm 236 according to the received offset information, thereby moving the core wire relative to the pad, so that the core wires on the same side are all located on the corresponding pads.

[0070] S5: During the first welding, the correction mechanism 230 maintains the position of the shift fork 237 and the wire core cable in step S4. The first CCD module 225 moves away from the welding station, and at the same time, the resistance welding assembly 226 moves to the welding station. The resistance welding assembly 226 welds the core wire on the same side. After welding, the resistance welding assembly 226 resets, and the correction mechanism 230 resets. During welding, since the core wire cable is still located in the receiving groove 238, the movement of the core wire is small during the welding process, especially the deformation of the unwelded core wire on the other side is small.

[0071] S6: Three image captures. The first CCD module 225 moves to the welding station again. The first CCD module 225 captures the image of the product welding area again and transmits the captured image to the controller. The controller processes the image to obtain the offset of the other core wire on the same side and the corresponding pad.

[0072] S7: Secondary cable manipulation. Based on the offset between the core wire on the same side and the corresponding pad in step S6, the controller controls multiple micro geared motors 232 to work independently. The micro geared motors 232 control the swinging arc of the swing arm 236 according to the received offset information, thereby manipulating the core wire cable to move relative to the pad, so that the core wire on the same side is located on the corresponding pad.

[0073] S8: Secondary welding, the correction mechanism 230 maintains the position of the shift fork 237 and the wire core cable in step S7, the first CCD module 225 moves away from the welding station, and at the same time the resistance welding assembly 226 moves to the welding station. The resistance welding assembly 226 welds the core wire on the same side. After the welding is completed, the resistance welding assembly 226 resets and the correction mechanism 230 resets.

[0074] S9: Product conveying. Product conveyor line 229 conveys the product that has been welded in S8 to the next station, and at the same time, conveys another product to be welded to the welding station.

[0075] In this embodiment, after the secondary welding, a product inspection step is also included. The first CCD module 225 captures an image of the product after the secondary welding and transmits the captured image to the controller. The controller processes the image and then determines whether the product welding meets the requirements.

[0076] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
