Description

Technical Field

[0001] This invention belongs to the field of welding technology, specifically an automatic plate feeding and welding device. Background Technology

[0002] Electrical engineering automated welding equipment is a device that integrates automation and welding technologies. It is mainly used to automate the welding process. Resistance welding is widely used, which is a method of welding by locally heating the workpiece and applying pressure at the same time through the resistance heat generated by the current at the workpiece and the contact point.

[0003] In existing electrical engineering automated welding devices, when performing resistance welding of two sets of plates, a robotic arm is typically used to grasp the plates, align and stack them, and then transfer them to the welding end for resistance welding. Pressure is then applied to perform the resistance welding operation. For automated welding operations involving batch processing, the robotic arm needs to repeatedly perform the processes of grasping, stacking, transferring, welding, and transferring again. This results in numerous robotic arm motions, high purchase costs, and generally low actual automated welding efficiency. Furthermore, if there is dirt on the plate surface, an additional cleaning step is required. Solid dirt adhering to the outer surface of the plate affects the contact treatment at the welding end, making the actual process even more complex. Overall, the automated welding efficiency is low, the cost is high, and the performance is unsatisfactory. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention aims to provide an automatic plate feeding and welding device, which solves the problems of low automation efficiency, high equipment cost, and lack of plate dirt treatment in the existing electrical engineering automated welding devices due to redundant robotic arm movements and dispersed processes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic sheet metal feeding and welding device includes a base. An electric push rod is respectively arranged on the inner side of the base, and a welding end is fixedly connected to the movable end of each electric push rod, with the two welding ends facing each other. A support ring is fixedly arranged above the base. Feeding components are fixedly arranged on the top of the support ring and on both end faces along the thickness direction. Each feeding component includes a storage frame. A transmission component is arranged at the bottom of the storage frame, near the support ring. The transmission component is engaged with a clamping component. An elastic fixing part is arranged on the other side of the clamping component, inside the storage frame.

Support portions are fixedly provided on both end faces of the support ring along the thickness direction. The support portions extend along the diameter direction of the support ring and include straight segments at both ends and a central annular segment. A rotation distribution portion is rotatably installed between the central annular segments of the support portions, and the center of the rotation distribution portion coincides with the center of the support ring. A swing assembly for placing the plate is symmetrically connected to the rotation distribution portion. The swing assembly rotates and intermittently pushes the transmission assembly to move.

[0006] Furthermore, the feeding assembly includes a storage frame, which is fixed to the two end faces of the top of the support ring along the thickness direction. A second electric push rod is inserted through the end of the storage frame away from the support ring. The movable end of the second electric push rod is located inside the storage frame and is fixedly connected to a push plate. The opposite ends of the two storage frames are interconnected and aligned to form a transfer channel connected to the interior of the swing assembly. The swing assembly is swingably disposed between the two storage frames to receive the sheet material from the storage frames.

[0007] Furthermore, the transmission assembly includes a toothed plate frame, a push rod, a support frame, a second spring, and a stop block. The toothed plate frame is slidably mounted on the support frame and engages with the clamping assembly. The stop block is located at the end of the support frame and fixed to the bottom of the storage frame. The push rod passes through the stop block and is connected to the toothed plate frame. The second spring is fixedly connected between the toothed plate frame and the stop block.

[0008] Furthermore, the clamping assembly includes an intermediate shaft, a cam, a torsion spring, and a gear. The intermediate shaft is rotatably sleeved on the bottom of the storage frame. The gear and the cam are both fixedly sleeved on the intermediate shaft. The gear meshes with the gear plate frame. The torsion spring is connected between the cam and the storage frame to provide a reset torque for the cam. The cam is located below the elastic fixing part and is used to push the elastic fixing part to achieve elastic lifting.

[0009] Furthermore, the elastic fixing part includes a mounting groove, a pressure plate, and a spring. The mounting groove is opened at the bottom of the inner cavity of the storage frame. The pressure plate is movably sleeved in the mounting groove. One end of the spring is fixedly connected to the mounting groove, and the other end is fixedly connected to the pressure plate. The cam is located below the pressure plate and is used to support or lower the plate inside the storage frame.

[0010] Furthermore, the rotating distribution unit includes a distribution disc, a rotating shaft, a second gear, a connecting port, a connecting ring, and a through hole; the rotating shaft is rotatably sleeved on the middle annular section of the support unit, the distribution disc is fixedly sleeved on the middle of the rotating shaft, the second gear is fixedly sleeved on one side of the rotating shaft, the connecting ring is fixedly sleeved on the other side of the rotating shaft and connected to the distribution disc, the outer side of the distribution disc has symmetrically opened connecting ports, the connecting ring has a through hole, and the through hole communicates with the connecting port; a drive gear is fixedly connected to the output shaft of the drive mechanism, the drive gear meshes with the second gear, and the distribution air passage communicates with the through hole.

[0011] Furthermore, the swing assembly includes a support frame, side grooves, a swing arm, and an internal cavity; the support frame is a U-shaped frame structure, including two vertical frames and a horizontal frame connecting the vertical frames, the two vertical frames have side grooves extending along the length of the vertical frames, the bottom of the horizontal frame of the support frame is fixedly connected to a swing arm, the swing arm is connected to the two vertical frames of the support frame with clamping parts respectively, and the bottom of the swing arm has an internal cavity, the swing assembly is fixedly connected to the distribution plate through the swing arm, and the internal cavity communicates with the communication port.

[0012] Furthermore, the clamping part includes a clamping plate, a side frame, a sleeve, a connecting pipe, a sleeve rod, and a spring. The clamping plate is movably sleeved in the side groove, the side frame is fixedly connected to the outer side of the support frame, the sleeve is fixedly connected to the side of the side frame, one end of the connecting pipe is fixedly connected to the sleeve, and the other end is fixedly connected to the swing arm and communicates with the internal cavity, one end of the sleeve rod passes through the side frame and is movably sleeved in the sleeve, and the other end is fixedly connected to the clamping plate, and the spring is fixedly connected between the clamping plate and the side frame.

[0013] Furthermore, the distribution air passage includes an annular cavity, a first hole, and a second hole. The annular cavity is formed on the central annular section of the support. The annular cavity has an annular groove structure, and a first hole and a second hole are formed in the annular cavity. The first hole and the second hole are arranged at intervals along the circumference of the annular cavity. The connecting ring is rotatably sleeved in the annular cavity. The first hole is connected to the air supply pump. Both the first hole and the second hole are located on the rotation path of the through hole. After the swing assembly rotates to the feeding assembly to receive the plate, the through hole aligns and connects with the first hole to realize airflow output. After the plate in the swing assembly is welded by the welding end, it moves to the discharge port, where the through hole aligns and connects with the second hole to realize exhaust and unloading.

[0014] Furthermore, cleaning plates are fixedly connected to both end faces of the support ring along the thickness direction.

[0015] The beneficial effects of this invention are as follows: 1. This invention achieves automatic bonding of two sets of plates to be welded before welding by coordinating a rotating feeding component, a transmission component, a clamping component, a swinging component, and an elastic fixing part. After bonding, the plates to be welded on both sides are kept stably fixed and clamped to prevent material from falling off. On the other hand, with the swinging component symmetrically distributed above and below, the next set is pre-automatically fed and clamped while one set is being welded. This optimizes the double-plate bonding and feeding process, improves the processing speed, and achieves high automated welding efficiency.

[0016] 2. This invention utilizes a drive mechanism to intermittently rotate the rotating distribution unit. In conjunction with the positioning of the feeding assembly, welding end, and discharge port on the support ring, automatic feeding, welding, and unloading are continuously completed in one rotation process during the intermittent rotation. When rotating to the top, feeding and clamping are performed; when rotating to the bottom, positioning welding is performed; and when continuing to deflect, automatic release of clamping and directional unloading are achieved. This results in a higher degree of automation and efficiency. Furthermore, the overall structure of the device is simple and compact, and it performs well in use.

[0017] 3. By coordinating the position of the cleaning plate with the rotation path of the swing assembly, the present invention completes synchronous cleaning during the movement towards welding after material loading, reducing the interference of solid deposits on the welding end, and eliminating the need for dedicated cleaning power equipment and special procedures. The cleaning process is integrated into the automatic welding process, further improving the efficiency of automated welding. At the same time, the friction action is used to complete the relative grinding of the outer surface of the metal plate, improving the welding quality. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-2 As shown, an automatic plate feeding and welding device is mainly composed of core components such as a base 1, a support ring 2, welding ends 4, a feeding assembly 5, a swing assembly 12, a rotation distribution part 19, and a drive mechanism 16. The base 1 serves as the supporting foundation for the entire device. Electric push rods 3 are respectively installed on its inner sides. The movable end of each electric push rod 3 is fixedly connected to a welding end 4. The two welding ends 4 are arranged facing each other. This arrangement allows the welding ends 4 on both sides to approach each other under the drive of the electric push rods 3 when the plate is transported to the welding position, thereby applying pressure to the plate and completing the resistance welding operation.

[0022] like Figure 5As shown, a support ring 2 is fixedly installed above the base 1. Feeding components 5 are fixedly installed on both sides of the top of the support ring 2 along its thickness direction. Starting from the feeding components 5, the sheet metal begins its automated flow journey within the device. The feeding components 5 include a storage frame 51, which is used to pre-store the sheet metal to be welded. A second electric push rod 52 passes through the end of the storage frame 51 away from the support ring 2. The movable end of the second electric push rod 52 is located inside the storage frame 51 and is fixedly connected to a push plate. The opposite ends of the two storage frames 51 are interconnected and aligned, forming a transfer channel connected to the interior of the swing assembly 12. When feeding is required, the second electric push rod 52 pushes the push plate, pushing the sheet metal in the storage frame 51 towards the center of the support ring 2, preparing it for subsequent reception by the swing assembly 12.

[0023] like Figure 6-7 As shown, a transmission assembly 10 is provided at the bottom of the storage frame 51 and near the support ring 2. The transmission assembly 10 includes a toothed plate frame 101, a push rod 102, a support frame 103, a second spring 104, and a stop block 105. The toothed plate frame 101 is slidably mounted on the support frame 103. The stop block 105 is located at the end of the support frame 103 and fixed to the bottom of the storage frame 51. The push rod 102 passes through the stop block 105 and is connected to the toothed plate frame 101. The second spring 104 is fixedly connected between the toothed plate frame 101 and the stop block 105. The transmission assembly 10 is meshed with a clamping assembly 9, which includes an intermediate shaft 91, a cam 92, a torsion spring 93, and a first gear 94. The intermediate shaft 91 is rotatably sleeved on the bottom of the storage frame 51. Gear 94 and cam 92 are both fixedly sleeved on the intermediate shaft 91, and gear 94 meshes with the gear plate frame 101. Torsion spring 93 is connected between cam 92 and storage frame 51 to provide reset torque for cam 92. On the other side of the clamping assembly 9 and inside the storage frame 51, an elastic fixing part is provided. The elastic fixing part includes a mounting groove 6, a pressure plate 7 and a spring 8. The mounting groove 6 is opened at the bottom of the inner cavity of the storage frame 51. The pressure plate 7 is movably sleeved in the mounting groove 6. One end of the spring 8 is fixedly connected to the mounting groove 6 and the other end is fixedly connected to the pressure plate 7. Cam 92 is located below pressure plate 7. When the swing assembly 12 rotates to the loading position and pushes the push rod 102, the push rod 102 drives the toothed plate frame 101 to slide on the support frame 103. The toothed plate frame 101 drives the gear 94 to rotate, causing the intermediate shaft 91 to drive the cam 92 to swing downward. The spring 8 drives the pressure plate 7 to move downward, putting down the board in the storage frame 51, so that the board can be accurately pushed into the swing assembly 12. After the swing assembly 12 leaves, the toothed plate frame 101 returns to its original position under the action of the spring 104, the gear 94 rotates in the opposite direction, the cam 92 returns to its original position under the action of the torsion spring 93, and the pressure plate 7 rises under the action of the spring 8, waiting for the next falling action.

[0024] like Figure 3-4As shown, support portions 11 are fixedly provided on both end faces of the support ring 2 along its thickness direction. Each support portion 11 extends along the diameter of the support ring 2 and includes straight sections at both ends and a central annular section. A rotation distribution portion 19 is rotatably mounted between the central annular sections of the support portions 11, and the center of the rotation distribution portion 19 coincides with the center of the support ring 2. Figure 11 As shown, the rotating distribution section 19 includes a distribution disk 191, a rotating shaft 192, a second gear 193, a connecting port 194, a connecting ring 195, and a through hole 196. The rotating shaft 192 is rotatably sleeved on the middle annular section of the support section 11. The distribution disk 191 is fixedly sleeved on the middle of the rotating shaft 192. The second gear 193 is fixedly sleeved on one side of the rotating shaft 192. The connecting ring 195 is fixedly sleeved on the other side of the rotating shaft 192 and connected to the distribution disk 191. The connecting ports 194 are symmetrically opened on the outer surface of the distribution disk 191. The connecting ring 195 has a through hole 196, and the through hole 196 communicates with the connecting port 194. A drive mechanism 16 is fixedly installed on the middle annular section of one of the support sections 11. A drive gear is fixedly connected to the output shaft of the drive mechanism 16. The drive gear meshes with the second gear 193 and is used to drive the rotating distribution section 19 to rotate.

[0025] like Figure 8 , 9 As shown, a swing assembly 12 for placing the plate is symmetrically connected to the rotating distribution part 19. The swing assembly 12 includes a support frame 121, a side groove 122, a swing arm 123, and an internal cavity 124. The support frame 121 has a U-shaped frame structure, including two vertical frames and a horizontal frame connecting the vertical frames. The two vertical frames have side grooves 122 that extend along the length of the vertical frames. The bottom of the horizontal frame of the support frame 121 is fixedly connected to the swing arm 123. Clamping parts 13 are respectively connected between the swing arm 123 and the two vertical frames of the support frame 121. The bottom of the swing arm 123 has an internal cavity 124. The swing assembly 12 is fixedly connected to the distribution plate 191 through the swing arm 123, and the internal cavity 124 communicates with the communication port 194. Figure 10 As shown, the clamping part 13 includes a clamping plate 131, a side frame 132, a sleeve 133, a connecting pipe 134, a sleeve rod 135, and a spring 136. The clamping plate 131 is movably sleeved in the side groove 122. The side frame 132 is fixedly connected to the outer side of the support frame 121. The sleeve 133 is fixedly connected to the side of the side frame 132. One end of the connecting pipe 134 is fixedly connected to the sleeve 133, and the other end is fixedly connected to the swing arm 123 and communicates with the internal cavity 124. One end of the sleeve rod 135 passes through the side frame 132 and is movably sleeved in the sleeve 133, and the other end is fixedly connected to the clamping plate 131. The spring 136 is fixedly connected between the clamping plate 131 and the side frame 132.

[0026] An air supply pump 14 is fixedly mounted on the central annular section of another support 11, and a distribution air passage 15 is provided thereon. Figure 12 As shown, the air distribution channel 15 includes an annular cavity 151, a first hole 152, and a second hole 153. The annular cavity 151 is formed on the central annular section of the support part 11. The annular cavity 151 has an annular groove structure. The first hole 152 and the second hole 153 are formed in the annular cavity 151, and the first hole 152 and the second hole 153 are arranged at intervals along the circumference of the annular cavity 151. The connecting ring 195 is rotatably sleeved in the annular cavity 151. The first hole 152 is connected to the air supply pump 14. Both the first hole 152 and the second hole 153 are located on the rotation path of the through hole 196. When the swing assembly 12 rotates to the feeding assembly 5 to receive the plate, the through hole 196 aligns and connects with the first hole 152. The airflow output by the air pump 14 sequentially enters the sleeve 133 through the first hole 152, the through hole 196, the connecting port 194, the internal cavity 124, and the connecting pipe 134. This pushes the sleeve rod 135 to move the clamping plate 131 along the side groove 122 towards the inside of the support frame 121, compressing the third spring 136, thereby clamping and fixing the plate. After the plate in the swing assembly 12 is welded by the welding end 4, it moves to the discharge port 18, where the through hole 196 aligns and connects with the second hole 153. The gas in the sleeve 133 is discharged through the connecting pipe 134, the internal cavity 124, the connecting port 194, the through hole 196, and the second hole 153. The clamping plate 131 resets under the action of the third spring 136, realizing exhaust and unloading.

[0027] In addition, such as Figure 4 As shown, cleaning plates 17 are fixedly connected to both end faces of the support ring 2 along the thickness direction. The cleaning plates 17 are arranged on the rotation path of the swing assembly 12. When the swing assembly 12 holds the plate and rotates from the loading position to the welding position, the outer side of the plate will contact the cleaning plate 17 and slide relative to it. The cleaning plate 17 can scrape and clean the solid dirt on the surface of the plate, reducing its interference with the contact treatment of the welding end 4. At the same time, it uses friction to polish the outer side of the metal plate to a certain extent, which is beneficial to improving the welding quality. According to the rotation direction of the rotation distribution part 19 and the swing assembly 12, a discharge port 18 is provided on the corresponding side of the lower part of the support ring 2 for the output of the plate after welding.

[0028] This invention provides an automatic sheet metal feeding and welding device, including a base 1, a primary electric push rod 3, and a welding end 4. A support ring 2 is fixedly mounted on the top of the base 1. Feeding components 5 are fixedly mounted on both sides of the top of the support ring 2. The feeding components 5 have an elastic fixing part inside, and a clamping component 9 is rotatably mounted inside the feeding components 5. A transmission component 10 is located at the bottom of the feeding components 5, and the transmission component 10 is meshed with the clamping component 9. Support parts 11 are fixedly mounted on both the front and back sides of the support ring 2. Rotation distribution parts 19 are rotatably mounted inside the two support parts 11. Symmetrical connections are made to the upper and lower sides of the rotation distribution parts 19. The swing assembly 12 has clamping parts 13 on both sides. A drive mechanism 16 is fixedly provided on the front of one support part 11. The drive mechanism 16 drives the rotation distribution part 19 to rotate. An air supply pump 14 is fixedly provided on the front of the other support part 11. The support part 11 has a distribution air passage 15 inside. The air supply pump 14 is connected to the rotation distribution part 19 through the distribution air passage 15 and controls the clamping part 13 to move. The swing assembly 12 intermittently pushes the transmission assembly 10 to move. When the rotation distribution part 19 rotates clockwise, the discharge port 18 is located on the lower left side of the support ring 2; when it rotates counterclockwise, it is located on the lower right side.

[0029] Example 1: In use, keep a set of swing components 12 rotating and stationary at the top. At this time, the swing arm 123 presses the push rod 102 in the transmission component 10, causing the toothed plate frame 101 to drive the meshing gear 94 to rotate, causing the intermediate shaft 91 to drive the cam 92 to swing downward, releasing the support of the elastic fixing part. The spring 8 drives the pressure plate 7 to move down, vertically placing the plate to be welded along the feed port 53 at the top of the storage frame 51. Start the second electric push rod 52, and the plates placed vertically in the two storage frames 51 move closer to each other. The two closest sets of plates are pushed into the support frame 121 of the swing component 12. Then start the air supply pump 14, which supplies pressurized air through the first hole 152. The air is fed into the through hole 196 and into the clamping part 13 through the connecting port 194 and the internal cavity 124. Pressurized air is also supplied into the sleeve 133 through the connecting pipe 134, pushing the internally fitted sleeve rod 135 to move. This causes the clamping plate 131 to move along the inside of the side groove 122, clamping and fixing the two sets of pressed and bonded plates. Then, the drive mechanism 16 is activated, causing the gear 193 in the rotating distribution part 19 to mesh and rotate. This causes the rotating shaft 192 to drive the distribution plate 191 to rotate, which in turn drives the swing assembly 12 to rotate. The swing assembly 12 causes the two sets of bonded plates to slowly rotate downwards along an arc trajectory. As the swing arm 123 moves away from the transmission assembly 10, it pushes... Rod 102 is elastically reset by spring 104, thereby driving the meshing gear 94 to rotate. This causes cam 92 to elastically reset upward and push pressure plate 7 upward. Pressure plate 7 then pushes the material to be loaded upward in storage frame 51, achieving clamping and fixing to prevent the material from detaching. When the swing assembly 12 drives the clamped material to swing, the front of the two sets of materials comes into frictional contact with cleaning plate 17, causing the solid particles of impurities attached to the front of the materials to detach, completing the cleaning. When the material rotates to the bottom, drive mechanism 16 stops, and electric push rod 3 is activated, driving the two sets of welding ends 4 to move synchronously and contact the front of the two sets of materials for resistance welding. After welding is completed, welding ends 4 move and reset, and drive mechanism 16 stops. The mechanism 16 is restarted and drives the swing assembly 12 to rotate upward. When the welded plate held in the swing assembly 12 moves to the discharge port 18, the through hole 196 in the rotating distribution part 19 connected with the second hole 153 in the distribution air channel 15. The pressurized air filled in the clamping part 13 bypasses through the second hole 153 in the reverse direction. The clamping part 13 is reset and the clamping is released. The welded plate that is no longer clamped falls automatically through the discharge port 18, completing the automatic orientation process. When the swing assembly 12 rotates to the top, it automatically pushes the transmission assembly 10 to move. The pressure plate 7 moves down, releases the clamping of the plate in the storage frame 51, and starts the second electric push rod 52 to perform the next round of positioning, fixing and automatic welding.

[0030] First, by utilizing the rotational feeding component 5, transmission component 10, clamping component 9, swing component 12, and elastic fixing part, the two sets of plates to be welded are automatically bonded before welding, and automatically clamped and fixed after bonding. After feeding, the plates to be welded on both sides are stably fixed and clamped to prevent material from falling off. On the other hand, with the swing component 12 symmetrically distributed above and below, the next set is pre-automatically fed and clamped while one set is being welded, which optimizes the double-plate bonding and feeding process, improves the processing speed, and achieves high automated welding efficiency.

[0031] Furthermore, by using the drive mechanism 16 to drive the rotation distribution part 19 to rotate intermittently, and in conjunction with the position arrangement of the feeding assembly 5, welding end 4 and discharge port 18 on the support ring 2, automatic feeding, welding and unloading can be completed continuously in one rotation process during the intermittent start-up rotation. When rotating to the top, feeding and clamping are performed; when rotating to the bottom, positioning welding is performed; and when continuing to deflect, automatic release of clamping and directional unloading are achieved. The degree of automation is higher, the efficiency is higher, and the overall structure of the device is simple and compact, with good performance.

[0032] On the other hand, in conjunction with the positioning of the cleaning plate 17, it is arranged on the rotation path of the swing component 12. It completes synchronous cleaning during the process of moving towards welding after loading, reducing the interference of solid deposits on the welding end. Moreover, there is no need for dedicated cleaning power equipment and special procedures. The cleaning process is integrated into the automatic welding process, which further improves the efficiency of automated welding.

[0037] The rotation distribution unit 19, in conjunction with the drive mechanism 16, achieves basic rotation control, completes the rotation of the swing assembly 12, drives the clamped and stacked plates to rotate to the welding area, and completes the welding process. The clamping unit 13 has a time lag compared to the pushing of the feeding assembly 5 when supplying air, ensuring that the plates are fixed after positioning.

[0039] By controlling the directional input and output of pressurized air through the distribution air passage 15, and coordinating the positions of the first hole 152 and the second hole 153, the clamping part 13 is inflated and clamped to position the pre-loaded plate when it is above.

[0042] The working principle and usage process of this invention are as follows: During use, a set of swing components 12 is kept rotating and stationary at the top. At this time, the swing arm 123 presses the push rod 102 in the transmission component 10, causing the toothed plate frame 101 to drive the meshing gear 94 to rotate. This causes the intermediate shaft 91 to drive the cam 92 to swing downwards, releasing the support of the elastic fixing part. The spring 8 drives the pressure plate 7 to move downwards, vertically placing the plate to be welded along the inlet 53 at the top of the storage frame 51. The second electric push rod 52 is activated, causing the vertically placed plates in the two storage frames 51 to move closer to each other. The two closest sets of plates are pushed into the support frame 121 of the swing component 12. Subsequently, the air supply pump 14 is activated, supplying pressurized air through... The air is fed into the through hole 152 and the through hole 196, and then into the clamping part 13 through the connecting port 194 and the internal cavity 124. Pressurized air is supplied into the sleeve 133 through the connecting pipe 134, pushing the internally fitted sleeve rod 135 to move. This causes the clamping plate 131 to move along the inside of the side groove 122, clamping and fixing the two sets of pressed and bonded plates. Then, the drive mechanism 16 is activated, driving the gear 193 in the rotating distribution part 19 to mesh and rotate. This causes the rotating shaft 192 to drive the distribution plate 191 to rotate, and also drives the swing assembly 12 to rotate. The swing assembly 12 causes the two sets of bonded plates to slowly rotate downwards along an arc trajectory. As the swing arm 123 moves from the transmission assembly 10... The push rod 102 is removed, and the spring 104 elastically resets it, thereby driving the meshing gear 94 to rotate. This causes the cam 92 to elastically reset upward and push the pressure plate 7 upward. The pressure plate 7 then pushes the material to be loaded upward in the storage frame 51, achieving clamping and fixing to prevent the material from falling off. When the swing assembly 12 drives the clamped material to swing, the front of the two sets of materials comes into frictional contact with the cleaning plate 17, causing the solid particles of impurities attached to the front of the material to fall off, completing the cleaning. When the material rotates to the bottom, the drive mechanism 16 stops, and the first electric push rod 3 is activated, driving the two sets of welding ends 4 to move synchronously and abut against the front of the two sets of materials. Resistance welding is then performed by applying electricity. After welding is completed, the welding ends 4 move and reset. The drive mechanism 16 starts again and drives the swing assembly 12 to rotate upward. When the welded plate held in the swing assembly 12 moves to the discharge port 18, the through hole 196 in the rotating distribution part 19 connects with the second hole 153 in the distribution air channel 15. The pressurized air filled in the clamping part 13 bypasses through the second hole 153 in the reverse direction. The clamping part 13 resets and releases the clamp. The welded plate that is no longer clamped falls automatically through the discharge port 18, completing the automatic orientation process. When the swing assembly 12 rotates to the top, it automatically pushes the transmission assembly 10 to move. The pressure plate 7 moves down, releases the clamp on the plate in the storage frame 51, and starts the second electric push rod 52 to perform the next round of positioning, fixing and automatic welding.
