Description

Technical Field

[0001] The invention belongs to the technical field of micro switch processing, in particular to an automatic welding device for a micro switch. Background Art

[0002] A micro switch is a switch device with a small contact interval and a fast action mechanism, usually used in small electrical equipment that requires manual operation. It uses external mechanical force to act on the action piece, which is transmitted through the transmission element to quickly connect or disconnect the fixed contact and the end moving contact, thereby achieving the connection or disconnection of the circuit.

[0003] The micro switch automatic welding device is an automated device used to efficiently and accurately weld the micro switch pins. This device usually combines advanced welding technology and automated control systems to improve production efficiency and welding quality.

[0004] A patent application with publication number CN116140912A discloses a fully automatic welding machine for micro switches, including a frame and a feeding mechanism. An eight-station turntable divider is provided in the middle of the frame. The divider is respectively provided with a flip feeding mechanism, a long-line welding mechanism, a flipping mechanism, a short-line welding station and a discharging mechanism corresponding to the stations. The lead welding operation is automatically completed with the assistance of the rotation of the divider, which greatly improves the production efficiency; it realizes fully automatic welding production with automatic feeding and automatic welding, greatly reduces the workload of workers, improves production efficiency, and avoids the occurrence of safety accidents.

[0005] In the current prior art, due to the certain plasticity of the wire, when welding the micro switch and the wire, the wire often bends, resulting in inaccurate positioning of the battery welding wire end and the micro switch pad, so that the two cannot be well welded together, which is prone to broken welding and loose welding, which is not conducive to production.

[0006] To this end, the present invention provides a micro switch automatic welding device. Summary of the invention

[0007] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0008] The technical solution adopted by the present invention to solve its technical problem is: the automatic welding device of a micro switch described in the present invention includes a box body and a conveying device, the box body is arranged on one side of the conveying device, a plurality of firmware boxes are arranged on the top of the conveying device, a plurality of firmware boxes are arranged inside each of the firmware components, the firmware components are used to fix the micro switch, a welding component is arranged inside the box body, the welding component is used to weld the wire and the micro switch, a wire straightening mechanism is arranged inside the box body, the wire straightening mechanism includes a pressing cylinder, the wire straightening mechanism is used to drive the pressing cylinder to straighten the wire, and the welding component is placed in the wire straightening mechanism Directly above, a rectangular box is fixedly installed on the inner wall of the box body, and a position adjustment component is arranged inside the rectangular box. The position adjustment component is used to drive the wire to calibrate with the pad on the micro switch, and the position adjustment component is placed directly below the wire-winding mechanism. A welding table is fixedly installed on one side of the rectangular box, and a slag removal component is arranged inside the welding table. The slag removal component is used to remove the residue left by the welding of the welding component. Vertical plates are symmetrically fixedly installed on the top of the rectangular box, and a wire storage box is fixedly installed between the two vertical plates. The wire-winding mechanism is placed between the two vertical plates. A driving component is arranged inside the box body, and the driving component is used to drive the wire-winding mechanism to move;

[0009] The micro switches are placed in the firmware box in sequence, and are fixed in place by the firmware components in the firmware box, and then the conveying device is driven to move the firmware box. When the firmware box drives the soldering pad of the micro switch to move to the welding table in the box, the conveying device stops working, and then the wire falls out of the wire storage box. When the wire falls out, the adjustment component in the matrix box drives the soldering wire end of the wire to calibrate with the soldering pad on the micro switch, and then the welding component moves down to weld the micro switch and the wire. When the welding component moves down, the driving component drives the wire straightening mechanism to move, so that the wire straightening mechanism drives the pressing cylinder to straighten the wire, so that the soldering wire end of the wire is placed at the center of the soldering pad on the micro switch to prevent the soldering wire end of the wire from being easily damaged due to the certain plasticity of the wire. The wire is bent, resulting in inaccurate positioning of the battery's welding wire end and the micro switch's welding pad. The two cannot be well welded together during welding, resulting in broken welds or loose welding. The wire is straightened to ensure that the wire and the micro switch remain in the same position, which is more conducive to the welding production of the micro switch and the wire. After the wire is straightened by the wire straightening mechanism, the welding assembly welds the two to weld the micro switch and the wire. Subsequently, the conveying device is driven to move the firmware box, thereby moving the micro switch out of the box. When the firmware box is moved out of the box, the firmware box drives the slag removal assembly in the welding table to remove the residue left by the welding of the welding assembly to prevent residue from being left on the top of the welding table, which is beneficial to the welding operation of the next micro switch and wire and plays a slag removal role.

[0010] Preferably, the welding assembly includes a motor, which is fixedly mounted on the top of the box body, and a screw shaft is fixedly mounted on the output end of the box body, one end of the screw shaft is rotatably connected to the top of the wire storage box, the outer wall of the screw shaft is threadedly connected to a lifting block, and a welding box is fixedly mounted on one side of the lifting block, and a plurality of welding nozzles are slidably connected to the bottom of the welding box. During welding, the motor drives the screw shaft to rotate, and when the screw shaft rotates, the screw shaft drives the lifting block to move downward, so that the lifting block drives the welding box to move downward, thereby causing the welding nozzle to move downward to weld the welding wire end of the wire with the welding pad of the micro switch, thereby playing the role of welding the wire and the micro switch.

[0011] Preferably, a gantry is fixedly installed on the outer wall of the conveying device, and a plurality of detection heads are fixedly installed on the top of the gantry. When the conveying device drives the firmware box to move, the detection head at the bottom of the gantry detects the micro switch in the firmware box, thereby determining the positions of the three pads of the micro switch, and then the positioning component drives the wire to move, thereby adjusting the position of the wire, so that the position of the wire end is corrected with the position of the pad on the micro switch, thereby detecting the position of the micro switch pad.

[0012] Preferably, the positioning assembly includes a hydraulic cylinder, which is fixedly installed inside the matrix box, and shift plates are fixedly installed at both output ends of the hydraulic cylinder. The outer walls of the two shift plates are slidably connected to the inner wall of the matrix box, and wire slot plates are fixedly installed on the top of the two shift plates and the middle position of the matrix box. The wire slot plates are used to place wires, and both sides of the multiple wire slot plates are fixedly installed with drop plates. The wire storage box is placed directly above the multiple wire slot plates. When the detection head determines the position of the three pads on the micro switch, the hydraulic cylinder drives the two wire slot plates to adjust their positions through the shift plate, so that the three wire slot plates are aligned with the pads on the micro switch. The positions of the three welding pads are kept consistent, which plays the role of calibrating the positions of the welding pads on the wires and the micro switches. The setting of the wire drop plate is to facilitate the falling movement of the wires in the wire storage box to prevent the wires from falling outside the wire slot plate. When welding is completed, the hydraulic cylinder drives the two shift plates to reset, which makes it easier for the wires in the wire storage box to fall into the wire slot plate. When the conveying device drives the micro switch in the firmware box to move to the welding table, a welding pad in the middle position of the micro switch is consistent with the wire slot plate placed in the middle position of the top of the matrix box, which is convenient for position adjustment, so that this device can be suitable for welding micro switches of different sizes.

[0013] Preferably, there are three groups of wire-winding mechanisms, which also include a wire-winding box and two pressing cylinders. The wire-winding box is placed inside one end of the wire-setting slot plate, and the inner wall of the wire-winding box is symmetrically slidably connected with two groups of sliding limit rods, one end of the two groups of sliding limit rods is respectively fixedly installed with a tube rack, the two ends of the two pressing cylinders are respectively rotatably connected to the inner walls of the two tube racks, and two groups of return springs are arranged between the inner wall of the wire-winding box and the top of the two tube racks, and the two groups of return springs are respectively placed on the outside of the two groups of sliding limit rods. When the wire falls into the wire-setting slot plate, the welding assembly drives the wire-winding box to move in the wire-setting slot plate through the driving assembly. When the wire-winding box moves in the wire-setting slot plate, the pressing cylinder in the wire-winding box will roll and squeeze the two sides of the wire, thereby moving the wire The wire is flattened. Since the glue protective cover on the outside of the wire is removed from the welding wire end of the wire, the diameter of the welding wire end of the wire will be smaller than the diameter of the wire itself. Therefore, when the wire drawing box drives the pressure cylinder to roll and squeeze the welding wire end of the wire, the pressure cylinder will make the cylinder wall of the pressure cylinder contact with the welding wire end of the wire under the push of the reset spring. Since the two pressure cylinders are arranged obliquely symmetrically, the welding wire end of the wire can be rolled and squeezed to the center of the wire slot plate, so that the position of the welding wire end of the wire and the center position of the welding pad on the micro switch are kept consistent from top to bottom, which is beneficial to the subsequent welding and can prevent the bending of the welding wire end of the wire from causing the position of the welding pad of the micro switch to change, affecting the welding accuracy between the two, and causing broken welding and leaking welding.

[0014] Preferably, the inner walls of one end of the two pressing cylinders are rotatably connected to a wire-pushing rod, and vertical blocks are symmetrically fixedly installed on one side of the two cylinder racks. The wire-pushing rod is placed between the two vertical blocks. When the pressing cylinder rolls and squeezes both sides of the wire, the wire-pushing rod smoothes both sides of the bottom of the wire to prevent the wire from deforming and bending to both sides, thereby straightening both sides of the wire.

[0015] Preferably, a rectangular plate is symmetrically fixedly installed on the outer wall of the wire slot plate, and the wire drawing box is slidably connected to the inner sides of the two rectangular plates. A sealing plate is fixedly installed on one end of the wire slot plate, and an inclined slide plate is symmetrically fixedly installed on the inner side of the sealing plate. The tops of the two inclined slide plates are arc sliding surfaces, and the tops of the two inclined slide plates are rotatably connected to the outer walls of the two pressing cylinders respectively. The setting of the rectangular plate and the sealing plate is convenient for the wire drawing box to be moved together with the wire slot plate inside the wire slot plate through the limiting of the rectangular plate and the sealing plate when the wire slot plate is shifted, so as to achieve synchronous movement. The inclined slide is provided to facilitate the rolling of the pressure cylinder around the guide wire to play a role of inclined sliding. The inclined slide can also limit the falling end of the wire, so that when the wire falls into the wire trough, one end of the wire is placed on one side of the inclined slide and fits with one side of the inclined slide. By setting the wire reel box on the outside of the inclined slide, a path can be provided for the falling of the wire. It should be noted here that the setting position of the inclined slide is slightly higher than the height of the wire, and the roller design of the pressure cylinder can also facilitate resetting.

[0016] Preferably, the driving assembly includes a gear rod 1, and there are two gear rods 1. The two gear rods 1 are fixedly installed on one side of the welding box respectively, one side of the two vertical plates are rotatably connected with a gear, the outer walls of the two vertical plates are slidably connected with gear rod 2, the outer walls of the two vertical plates are fixedly installed with limit blocks, the outer walls of the two gear rods 2 and gear rod 1 are slidably connected with the outer walls of the two limit blocks respectively, the teeth on the two gear rods 1 and gear rod 2 are respectively meshed with the teeth on the two gears, one end of the two vertical plates is fixedly installed with a groove block, the two groove blocks are respectively slidably connected with the inner walls of the two vertical plates, a T-shaped rod is fixedly installed on the top of the wire drawing box located in the middle position, and connecting rods are fixedly installed on the top of the wire drawing boxes located on both sides, the two ends of the T-shaped rod are respectively slidably connected with the inner walls of the two connecting rods, and one end of the two connecting rods is respectively connected to the two grooves The inner wall of the block is slidably connected. When the motor drives the welding box to move downward, the welding box drives the gear rod to move downward, so that the gear rod one drives the gear rod two to move through the gear meshing transmission, and the gear rod two can drive the wire-winding box to slide in the wire-setting slot plate, so that the two pressure cylinders and the wire-pulling rod straighten and calibrate the wires, thereby driving the wire-winding box to move. When the adjustment component drives the wire-setting slot plate to move, since the wire-setting slot plate located in the middle position is stationary, when the adjustment component drives the wire-setting slot plates on both sides to move, one end of the two connecting rods moves on the outer walls of the two ends of the T-bar, and the other ends of the two connecting rods slide inside the two slot blocks, so that when the three wire-setting slot plates are adjusting their positions, the three wire-winding boxes can be integrated through the T-bar and the connecting rod, which is convenient for the subsequent gear rod two to move the wire-winding boxes.

[0017] Preferably, the slag removal assembly includes a push rod plate, a slag pushing rod is fixedly installed on the top of the push rod plate, the top of the push rod plate is slidably connected to the inner wall of the welding table, the bottom of the slag pushing rod is slidably connected to the top of the welding table, one side of the shaft rod is symmetrically fixedly installed with a shaft rod, the outer walls of the two shaft rods are slidably connected to the inner wall of the rectangular box, pressure springs are symmetrically arranged between one side of the push rod plate and the outer wall of the rectangular box, the two pressure springs are respectively placed on the outside of the two shaft rods, and the bottom of the firmware box is symmetrically fixedly installed with push rods, one end of the two push rods is slidably connected to the other side of the push rod plate, one end of the two push rods are both inclined sliding mouths, and the push rod plate One end of the welding table is an inclined sliding surface, and a slag dropping groove is provided on the inner wall of the welding table. When the conveying device drives the firmware box to move into the box, the push rod at the bottom of the firmware box squeezes and pushes the push rod plate to move, so that the push rod plate drives the slag pushing rod to slide inward on the top of the welding table. When welding is completed, the conveying device drives the firmware box to move out of the box. At this time, the push rod plate will lose the thrust of the push rod, and the push rod plate will slide and reset on the top of the welding table under the action of the elastic reset force of the pressure spring, so that the welding slag on the top of the welding table will be scraped into the slag dropping groove, which is convenient for the next welding operation and plays a role in slag removal.

[0018] Preferably, the firmware assembly includes a limiting plate, which is fixedly mounted on one side of the firmware box, and a clamping block is slidably connected to the other side of the firmware box, and a return spring is arranged between one side of the clamping block and the inner wall of the firmware box, and the top of the return spring is an inclined surface. When the micro switch is placed, one side of the micro switch is attached to the limiting plate by using a mechanical arm, and then pressed downward, the micro switch will squeeze and push the clamping block to move downward, and when the bottom of the micro switch contacts the bottom of the firmware box, the clamping block will fix the micro switch in place under the elastic push of the return spring, thereby placing the micro switch, and through the arrangement of the clamping block and the return spring, the firmware box can fix micro switches of different sizes when it is fixed.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The automatic welding device for a micro switch described in the present invention can flatten the wire by rolling and squeezing the two sides of the wire through the pressure cylinder in the wire-winding box, and can roll and squeeze the welding wire end of the wire to the center of the wire slot plate, so that the position of the welding wire end of the wire is kept consistent with the center position of the welding pad on the micro switch. When the pressure cylinder rolls and squeezes the two sides of the wire, the wire-pulling rod smoothes the bottom two sides of the wire to prevent the wire from deforming and bending to the two sides, which can prevent the bending of the welding wire end of the wire from causing a change in the position of the welding pad of the micro switch, affecting the welding accuracy between the two, and causing broken welding and leaking welding.

[0021] 2. The automatic welding device for a micro switch described in the present invention drives two wire slot plates to adjust their positions through a hydraulic cylinder via a shift plate, so that the positions of the three wire slot plates and the three welding pads on the micro switch are kept consistent, thereby playing a role in calibrating the positions of the wires and the welding pads on the micro switch, so that the device can be suitable for welding micro switches of different sizes.

[0022] 3. The micro switch automatic welding device described in the present invention pushes the push rod plate to move by squeezing the push rod at the bottom of the firmware box, so that the push rod plate drives the slag push rod to slide inward on the top of the welding table. When welding is completed, the conveying device drives the firmware box out of the box body, and the push rod plate loses the thrust of the push rod. Under the action of the elastic reset force of the pressure spring, the push rod plate slides and resets on the top of the welding table, thereby scraping the welding slag on the top of the welding table into the slag trough, which is convenient for the next welding operation and plays a role in slag removal.

[0023] 4.

[0024] 5. The automatic welding device for a micro switch described in the present invention detects the micro switch in the firmware box when the conveying device drives the firmware box to move, thereby determining the positions of the three pads of the micro switch. Subsequently, the positioning component drives the wire to move, thereby adjusting the position of the wire, so that the position of the wire end is corrected with the position of the pad on the micro switch, thereby detecting the position of the micro switch pad.

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] like Figures 1 to 13As shown, an automatic welding device for a micro switch according to an embodiment of the present invention comprises a box body 1 and a conveying device 2, wherein the box body 1 is arranged on one side of the conveying device 2, a plurality of fixing boxes 3 are arranged on the top of the conveying device 2, a fixing assembly is arranged inside each of the plurality of fixing boxes 3, the fixing assembly is used to fix the micro switch, a welding assembly is arranged inside the box body 1, the welding assembly is used to weld the wire and the micro switch, a wire straightening mechanism is arranged inside the box body 1, the wire straightening mechanism comprises a pressing cylinder 1502, the wire straightening mechanism is used to drive the pressing cylinder 1502 to straighten the wire, the welding assembly is placed directly above the wire straightening mechanism, and the box body A rectangular box 10 is fixedly installed on the inner wall of the rectangular box 10, and a position adjustment component is arranged inside the rectangular box 10. The position adjustment component is used to drive the wire to calibrate with the pad on the micro switch. The position adjustment component is placed directly below the wire-straightening mechanism. A welding table 9 is fixedly installed on one side of the rectangular box 10. A slag removal component is arranged inside the welding table 9. The slag removal component is used to remove the residue left by the welding of the welding component. Vertical plates 8 are symmetrically fixedly installed on the top of the rectangular box 10. A wire storage box 6 is fixedly installed between the two vertical plates 8. The wire-straightening mechanism is placed between the two vertical plates 8. A driving component is arranged inside the box body 1. The driving component is used to drive the wire-straightening mechanism to move.

[0042] When welding the micro switch and the wire, if the wire is bent, the battery welding wire end and the micro switch pad position will not be accurate, and the two cannot be welded together well during welding;

[0043] During operation, the micro switches are placed in the firmware box 3 in sequence, and are fixed in place by the firmware components in the firmware box 3. Then, the conveying device 2 is driven to drive the firmware box 3 to move. When the firmware box 3 drives the soldering pad of the micro switch to move to the welding table 9 in the box body 1, the conveying device 2 stops working, and then the wire falls out of the wire storage box 6. When the wire falls out, the positioning component in the matrix box 10 drives the soldering wire end of the wire to align with the soldering pad on the micro switch, and then the welding component moves down to weld the micro switch and the wire. When the welding When the component moves downward, the driving component drives the wire-straightening mechanism to move, so that the wire-straightening mechanism drives the pressing cylinder 1502 to straighten the wire, so that the welding wire end of the wire is placed at the center of the pad on the micro switch, to prevent the welding wire end of the wire from bending easily due to the plasticity of the wire, resulting in inaccurate position of the welding wire end of the battery and the pad of the micro switch, and the two cannot be well welded together during welding, resulting in broken welding or loose welding. The wire-straightening ensures that the wire and the micro switch remain in the same position, which is more conducive to the micro switch. In the welding production of the micro switch and the wire, after the wire straightening mechanism straightens the wire, the welding assembly welds the two together, which plays the role of welding the micro switch and the wire. Then the conveying device 2 is driven to drive the firmware box 3 to move, so that the micro switch is moved out of the box body 1. When the firmware box 3 is moved out of the box body 1, the firmware box 3 drives the slag removal assembly in the welding table 9 to remove the residue left by the welding of the welding assembly, so as to prevent residue from being left on the top of the welding table 9, which is beneficial to the welding operation of the next micro switch and the wire, and plays the role of slag removal. Repeat this process , the micro switch and the wire can be welded. It should be noted that a wire throwing mechanism is arranged inside the wire storage box 6. The wire throwing mechanism is used to drive the wire to move out of the wire storage box 6. The wire throwing mechanism consists of a driving component and a throwing component. When throwing the wire, the driving component drives the throwing component to throw the wire out of the wire storage box 6. The conveying device 2 can be an intermittent conveyor belt, which is the prior art. The micro switch welded by this device is a three-disc welding micro switch. In the attached figure, the number 20 represents the micro switch, and the number 21 represents the wire, both of which are the prior art.

[0044] like Figure 3 to Figure 4 As shown, the welding assembly includes a motor 4, which is fixedly mounted on the top of the box body 1, and a screw shaft 402 is fixedly mounted on the output end of the box body 1, one end of the screw shaft 402 is rotatably connected to the top of the wire storage box 6, and a lifting block 401 is threadedly connected to the outer wall of the screw shaft 402, and a welding box 7 is fixedly mounted on one side of the lifting block 401, and a plurality of welding nozzles 701 are slidably connected to the bottom of the welding box 7;

[0045] During welding, the motor 4 drives the screw shaft 402 to rotate. When the screw shaft 402 rotates, the screw shaft 402 drives the lifting block 401 to move downward, so that the lifting block 401 drives the welding box 7 to move downward, thereby causing the welding nozzle 701 to move downward to weld the welding wire end of the wire with the welding pad of the micro switch, thereby playing the role of welding the wire and the micro switch. It should be noted here that a soldering mechanism and a soldering transfer mechanism should be provided inside the welding box 7. The soldering mechanism is used to solder the wire and the micro switch through the soldering nozzle 701, and the soldering transfer mechanism is used to drive the three welding nozzles 701 to adjust their positions, so that the three welding nozzles 701 can be moved according to the position adjustment of the positioning component.

[0046] like Figure 1 to Figure 2 As shown, a gantry 5 is fixedly installed on the outer wall of the conveying device 2, and a plurality of detection heads 501 are fixedly installed on the top of the gantry 5;

[0047] When the conveying device 2 drives the firmware box 3 to move, the detection head 501 at the bottom of the gantry 5 detects the micro switch in the firmware box 3, so as to determine the positions of the three pads of the micro switch. Then the positioning component drives the wire to move, so as to adjust the position of the wire, so that the position of the wire end is calibrated with the position of the pad on the micro switch, thereby detecting the position of the pad of the micro switch.

[0048] like Figures 4 to 11 As shown, the positioning assembly includes a hydraulic cylinder 14, which is fixedly installed inside the matrix box 10, and the output ends of both ends of the hydraulic cylinder 14 are fixedly installed with shift plates 13, and the outer walls of the two shift plates 13 are slidably connected to the inner wall of the matrix box 10, and the tops of the two shift plates 13 and the middle position of the matrix box 10 are fixedly installed with wire slot plates 12, which are used to place wires, and both sides of the multiple wire slot plates 12 are fixedly installed with wire drop plates 11, and the wire storage box 6 is placed directly above the multiple wire slot plates 12;

[0049] When the detection head 501 determines the position of the three pads on the microswitch, the hydraulic cylinder 14 drives the two wire slot plates 12 to adjust their positions through the shift plate 13, so that the three wire slot plates 12 are consistent with the three pads on the microswitch, which plays a role in calibrating the positions of the wires and the pads on the microswitch. The setting of the wire drop plate 11 is to facilitate the falling movement of the wires in the wire storage box 6 to prevent the wires from falling outside the wire slot plates 12. When the welding is completed, the hydraulic cylinder 14 drives the two shift plates 13 to reset, so that the wires in the wire storage box 6 fall into the wire slot plates 12. When the conveying device 2 drives the microswitch in the firmware box 3 to move to the welding table 9, a pad at the middle position on the microswitch is consistent with the wire slot plate 12 placed at the middle position on the top of the matrix box 10, which is convenient for position adjustment, so that the device can be suitable for welding microswitches of different sizes.

[0050] like Figures 6 to 8 As shown, there are three groups of wire-winding mechanisms, which also include a wire-winding box 15, and two pressing cylinders 1502. The wire-winding box 15 is placed inside one end of the wire-setting slot plate 12, and the inner wall of the wire-winding box 15 is symmetrically slidably connected with two groups of limit slide rods 1505, and one end of the two groups of limit slide rods 1505 is respectively fixedly installed with a cylinder rack 1503, and the two ends of the two pressing cylinders 1502 are respectively rotatably connected to the inner walls of the two cylinder racks 1503, and two groups of return springs 1504 are arranged between the inner wall of the wire-winding box 15 and the tops of the two cylinder racks 1503, and the two groups of return springs 1504 are respectively placed outside the two groups of limit slide rods 1505;

[0051] When the wire falls into the wire slot plate 12, the welding assembly drives the wire box 15 to move in the wire slot plate 12 through the driving assembly. When the wire box 15 moves in the wire slot plate 12, the pressing cylinder 1502 in the wire box 15 will roll and squeeze the two sides of the wire, thereby flattening the wire. Since the wire welding end of the wire has removed the rubber protective cover on the outside of the wire, the diameter of the wire welding end will be smaller than the diameter of the wire itself. Therefore, when the wire box 15 drives the pressing cylinder 1502 to roll and squeeze the wire welding end of the wire, the pressing cylinder 1502 will be pushed by the reset spring 1504 to make the cylinder wall of the pressing cylinder 1502 contact with the wire welding end of the wire. Since the two pressing cylinders 1502 are arranged obliquely symmetrically , the welding wire end of the wire can be rolled and squeezed to the center of the wire slot plate 12, so that the position of the welding wire end of the wire is consistent with the center position of the welding pad on the micro switch, which is beneficial to the subsequent welding. It can prevent the welding wire end of the wire from bending, which causes the position of the welding pad of the micro switch to change, affecting the welding accuracy between the two, and causing broken welding and leaking welding. It should be noted here that the length of the wire slot plate 12 is slightly longer than the length of the wire, and a through hole is opened at one end of the wire slot plate 12. The size of the through hole is the same as the size of the welding nozzle 701. The elastic force of the reset spring 1504 needs to be designed according to actual needs, and the inclination angle of the two pressure cylinders 1502 should be less than ninety degrees.

[0052] like Figures 8 to 9 As shown, the inner wall of one end of the two pressing cylinders 1502 is rotatably connected with a wire-pushing rod 1501, and one side of the two cylinder-receiving racks 1503 is symmetrically fixed with a vertical block 1506, and the wire-pushing rod 1501 is placed between the two vertical blocks 1506;

[0053] When the pressing cylinder 1502 rolls and squeezes the two sides of the wire, the wire-pulling rod 1501 smoothes the two sides of the bottom of the wire to prevent the wire from deforming and bending to the two sides, thereby straightening the two sides of the wire.

[0054] like Figures 8 to 10As shown, the outer wall of the wire slot plate 12 is symmetrically fixed with a rectangular plate 16, the wire reeling box 15 is slidably connected to the inner sides of the two rectangular plates 16, a sealing plate 17 is fixedly installed at one end of the wire slot plate 12, and an inclined slide plate 18 is symmetrically fixedly installed on the inner side of the sealing plate 17, the tops of the two inclined slide plates 18 are arc sliding surfaces, and the tops of the two inclined slide plates 18 are rotatably connected to the outer walls of the two pressing cylinders 1502 respectively;

[0055] During operation, the setting of the rectangular plate 16 and the sealing plate 17 is convenient for the wire trough plate 12 to be displaced. Through the limiting of the rectangular plate 16 and the sealing plate 17, the wire reeling box 15 can be driven to displace together with the wire trough plate 12 inside the wire trough plate 12, thereby playing a role of synchronous displacement. The setting of the inclined slide plate 18 is convenient for the pressing cylinder 1502 to roll around the body of the guide wire, thereby playing a role of inclined sliding. The setting of the inclined slide plate 18 can also limit the falling end of the wire, so that when the wire falls into the wire trough plate 12, one end of the wire is placed on one side of the inclined slide plate 18 and fits with one side of the inclined slide plate 18. By setting the wire reeling box 15 on the outside of the inclined slide plate 18, a path can be provided for the falling of the wire. It should be noted here that the setting position of the inclined slide plate 18 is slightly higher than the height of the wire, and the roller design of the pressing cylinder 1502 can also facilitate resetting.

[0056] like Figures 3 to 6 As shown, the driving assembly includes a gear rod 1 702, and there are two gear rods 1 702. The two gear rods 1 702 are respectively fixedly installed on one side of the welding box 7. One side of the two vertical plates 8 is rotatably connected with a gear 703. The outer walls of the two vertical plates 8 are slidably connected with a gear rod 2 704. The outer walls of the two vertical plates 8 are fixedly installed with a limit block 804. The outer walls of the two gear rods 2 704 and the gear rod 1 702 are respectively slidably connected with the outer walls of the two limit blocks 804. The teeth are respectively meshed with the teeth on the two gears 703, a slot block 803 is fixedly installed at one end of the two vertical plates 8, and the two slot blocks 803 are respectively slidably connected to the inner walls of the two vertical plates 8, a T-shaped rod 802 is fixedly installed on the top of the wire-winding box 15 located in the middle position, and connecting rods 801 are fixedly installed on the top of the wire-winding boxes 15 located on both sides, and the two ends of the T-shaped rod 802 are respectively slidably connected to the inner walls of the two connecting rods 801, and one end of the two connecting rods 801 is respectively slidably connected to the inner walls of the two slot blocks 803;

[0057] When the motor 4 drives the welding box 7 to move downward, the welding box 7 drives the gear rod 1 702 to move downward, so that the gear rod 1 702 drives the gear rod 2 704 to move through the meshing transmission of the gear 703, and the gear rod 2 704 can drive the wire straightening box 15 to slide in the wire slot plate 12, so that the two pressure cylinders 1502 and the wire-pulling rod 1501 can straighten and calibrate the wires, thereby driving the wire straightening box 15 to move. When the positioning component drives the wire slot plate 12 to move, since the wire slot plate 12 located in the middle position is stationary, when the positioning component drives the two sides of the wire slot plate 12 to move, When the wire slot plate 12 moves, one end of the two connecting rods 801 moves on the outer walls at both ends of the T-shaped rod 802, and the other ends of the two connecting rods 801 slide inside the two slot blocks 803, so that when the three wire slot plates 12 are adjusting their positions, the three wire reeling boxes 15 can be integrated through the T-shaped rod 802 and the connecting rod 801, which is convenient for the subsequent gear rod 2 704 to move the wire reeling box 15. It should be noted here that the teeth on the gear rod 2 704 and the gear rod 1 702 are consistent, and the length dimensions of the two are greater than the length dimension of the wire slot plate 12.

[0058] like Figure 11 to Figure 12 As shown, the slag removal assembly includes a push rod plate 19, a slag pusher 1901 is fixedly installed on the top of the push rod plate 19, the top of the push rod plate 19 is slidably connected to the inner wall of the welding table 9, the bottom of the slag pusher 1901 is slidably connected to the top of the welding table 9, one side of the shaft rod 1902 is symmetrically fixedly installed with the shaft rod 1902, the outer walls of the two shaft rods 1902 are slidably connected to the inner wall of the rectangular box 10, and pressure springs 1903 are symmetrically arranged between one side of the push rod plate 19 and the outer wall of the rectangular box 10, and the two pressure springs 1903 are respectively placed on the outside of the two shaft rods 1902, and the bottom of the firmware box 3 is symmetrically fixedly installed with push rods 301, one end of the two push rods 301 is slidably connected to the other side of the push rod plate 19, one end of the two push rods 301 are both inclined sliding openings, one end of the push rod plate 19 is an inclined sliding surface, and the inner wall of the welding table 9 is provided with a slag dropping groove 901;

[0059] When the conveying device 2 drives the firmware box 3 to move into the box body 1, the push rod 301 at the bottom of the firmware box 3 squeezes and pushes the push rod plate 19 to move, so that the push rod plate 19 drives the slag pushing rod 1901 to slide inward on the top of the welding table 9. When welding is completed, the conveying device 2 drives the firmware box 3 to move out of the box body 1. At this time, the push rod plate 19 will lose the thrust of the push rod 301, and under the action of the elastic reset force of the pressure spring 1903, the push rod plate 19 will slide and reset on the top of the welding table 9, thereby scraping the welding slag on the top of the welding table 9 into the slag trough 901, which is convenient for the next welding operation and plays a role in removing slag. It should be noted here that the welding table 9 is made of brass.

[0060] like Figure 12 to Figure 13As shown, the firmware assembly includes a limiting plate 303, which is fixedly installed on one side of the firmware box 3, and a clamping block 302 is slidably connected to the other side of the firmware box 3. A return spring 304 is arranged between one side of the clamping block 302 and the inner wall of the firmware box 3, and the top of the return spring 304 is an inclined surface;

[0061] When the micro switch is to be placed, a mechanical arm is used to fit one side of the micro switch to the limiting plate 303, and then it is pressed downward. The micro switch will squeeze and push the clamp block 302 to move downward. When the bottom of the micro switch contacts the bottom of the firmware box 3, the clamp block 302 will fix the micro switch in place under the elastic push of the return spring 304, thereby placing the micro switch. Through the arrangement of the clamp block 302 and the return spring 304, the firmware box 3 can fix micro switches of different sizes when it is fixed.

[0062] Working principle: the micro switches are placed in the firmware box 3 in sequence, and the firmware components in the firmware box 3 are used to fix them in place, and then the conveying device 2 is driven to drive the firmware box 3 to move. When the firmware box 3 drives the soldering pad of the micro switch to move to the welding table 9 in the box body 1, the conveying device 2 stops working, and then the wire falls out of the wire storage box 6. When the wire falls out, the adjustment component in the matrix box 10 drives the soldering wire end of the wire to calibrate with the soldering pad on the micro switch, and then the welding component moves down to weld the micro switch and the wire. When the welding component moves down, the driving component drives the wire straightening mechanism to move, so that the wire straightening mechanism drives the pressing cylinder 1502 to straighten the wire, so that the soldering wire end of the wire is placed at the center of the soldering pad on the micro switch to prevent the wire from being deformed due to the certain plasticity of the wire. The welding wire end is prone to bending, resulting in inaccurate positioning of the welding wire end of the battery and the welding pad of the micro switch. The two cannot be well welded together during welding, resulting in broken welding or loose welding. The wire is straightened to ensure that the wire and the micro switch remain in the same position, which is more conducive to the welding production of the micro switch and the wire. After the wire is straightened by the wire straightening mechanism, the welding assembly welds the two to weld the micro switch and the wire. Then the conveying device 2 is driven to drive the firmware box 3 to move, so that the micro switch is moved out of the box body 1. When the firmware box 3 is moved out of the box body 1, the firmware box 3 drives the slag removal assembly in the welding table 9 to remove the residue left by the welding of the welding assembly, so as to prevent residue from being left on the top of the welding table 9, which is conducive to the welding operation of the next micro switch and the wire, and plays a role in slag removal;

[0063] During welding, the motor 4 drives the screw shaft 402 to rotate. When the screw shaft 402 rotates, the screw shaft 402 drives the lifting block 401 to move downward, so that the lifting block 401 drives the welding box 7 to move downward, so that the welding nozzle 701 moves downward to weld the welding wire end of the wire and the welding pad of the micro switch, thereby playing the role of welding the wire and the micro switch;

[0064] When the conveying device 2 drives the firmware box 3 to move, the detection head 501 at the bottom of the gantry 5 detects the micro switch in the firmware box 3, thereby determining the positions of the three pads of the micro switch, and then the positioning component drives the wire to move, thereby adjusting the position of the wire, so that the position of the wire end is aligned with the pad position on the micro switch, thereby detecting the position of the pad of the micro switch;

[0065] When the detection head 501 determines the position of the three pads on the micro switch, the hydraulic cylinder 14 drives the two wire slot plates 12 to adjust their positions through the shift plate 13, so that the three wire slot plates 12 are consistent with the three pads on the micro switch, which plays the role of calibrating the position of the wires and the pads on the micro switch. The setting of the wire drop plate 11 is to facilitate the wires in the wire storage box 6 to fall and move, and prevent the wires from falling outside the wire slot plate 12. When welding is completed, the hydraulic cylinder 14 drives the two shift plates 13 to reset, so that the wires in the wire storage box 6 fall into the wire slot plate 12. When the conveying device 2 drives the micro switch in the firmware box 3 to move to the welding table 9, a pad at the middle position on the micro switch is consistent with the wire slot plate 12 placed at the middle position of the top of the matrix box 10, which is convenient for position adjustment, so that the device can be used for welding micro switches of different sizes.

[0066] When the wire falls into the wire slot plate 12, the welding assembly drives the wire box 15 to move in the wire slot plate 12 through the driving assembly. When the wire box 15 moves in the wire slot plate 12, the pressing cylinder 1502 in the wire box 15 will roll and squeeze the two sides of the wire, thereby flattening the wire. Since the wire welding end of the wire has removed the gelatin protective cover outside the wire, the diameter of the wire welding end will be smaller than the wire itself. Therefore, when the wire box 15 drives the pressing cylinder 1502 to roll and squeeze the wire welding end of the wire, the pressing cylinder 150 2, under the push of the reset spring 1504, the wall of the pressure cylinder 1502 will contact the welding wire end of the wire. Since the two pressure cylinders 1502 are arranged obliquely symmetrically, the welding wire end of the wire can be rolled and squeezed to the center of the wire slot plate 12, so that the position of the welding wire end of the wire is consistent with the center position of the welding pad on the micro switch, which is beneficial to the subsequent welding and can prevent the bending of the welding wire end of the wire from causing the position of the welding pad of the micro switch to change, affecting the welding accuracy between the two, and causing the phenomenon of broken welding and leaking welding;

[0067] When the pressing cylinder 1502 rolls and squeezes the two sides of the wire, the wire-pulling rod 1501 smoothes the two sides of the bottom of the wire to prevent the wire from deforming and bending to the two sides, thereby straightening the two sides of the wire.

[0068] The setting of the rectangular plate 16 and the sealing plate 17 is convenient for when the wire slot plate 12 is displaced. Through the limiting of the rectangular plate 16 and the sealing plate 17, the wire reeling box 15 can be driven to displace together with the wire slot plate 12 inside the wire slot plate 12, so as to play a role of synchronous displacement. The setting of the inclined slide plate 18 is convenient for the pressing cylinder 1502 to roll around the body of the wire, so as to play a role of inclined sliding. The setting of the inclined slide plate 18 can also limit the falling end of the wire, so that when the wire falls into the wire slot plate 12, one end of the wire is placed on one side of the inclined slide plate 18 and fits with one side of the inclined slide plate 18. By setting the wire reeling box 15 on the outside of the inclined slide plate 18, a path can be provided for the falling of the wire. It should be noted that the setting position of the inclined slide plate 18 is slightly higher than the height of the wire, and the roller design of the pressing cylinder 1502 can also facilitate resetting.

[0069] When the motor 4 drives the welding box 7 to move downward, the welding box 7 drives the gear rod 1 702 to move downward, so that the gear rod 1 702 drives the gear rod 2 704 to move through the meshing transmission of the gear 703, and the gear rod 2 704 can drive the wire straightening box 15 to slide in the wire slot plate 12, so that the two pressing cylinders 1502 and the wire-pulling rod 1501 can straighten and calibrate the wire, thereby driving the wire straightening box 15 to move. When the positioning assembly drives the wire slot plate 12 to move, due to the middle position of the wire One wire slot plate 12 is stationary, so when the positioning assembly drives the wire slot plates 12 on both sides to move, one end of the two connecting rods 801 moves on the outer walls of the two ends of the T-shaped rod 802, and the other ends of the two connecting rods 801 slide inside the two slot blocks 803, so that when the three wire slot plates 12 are adjusted in position, the three wire winding boxes 15 can be integrated through the T-shaped rod 802 and the connecting rod 801, which is convenient for the subsequent gear rod 2 704 to move the wire winding box 15;

[0070] When the conveying device 2 drives the firmware box 3 to move into the box body 1, the push rod 301 at the bottom of the firmware box 3 squeezes and pushes the push rod plate 19 to move, so that the push rod plate 19 drives the slag push rod 1901 to slide inward on the top of the welding table 9. When welding is completed, the conveying device 2 drives the firmware box 3 to move out of the box body 1. At this time, the push rod plate 19 will lose the thrust of the push rod 301, and the push rod plate 19 will slide and reset on the top of the welding table 9 under the action of the elastic reset force of the pressure spring 1903, so that the welding slag placed on the top of the welding table 9 is scraped off into the slag trough 901, which is convenient for the next welding operation and plays a role in slag removal.

[0071] When the micro switch is to be placed, a mechanical arm is used to fit one side of the micro switch to the limiting plate 303, and then it is pressed downward. The micro switch will squeeze and push the clamp block 302 to move downward. When the bottom of the micro switch contacts the bottom of the firmware box 3, the clamp block 302 will fix the micro switch in place under the elastic push of the return spring 304, thereby placing the micro switch. Through the arrangement of the clamp block 302 and the return spring 304, the firmware box 3 can fix micro switches of different sizes when it is fixed.
