[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figure 1-17 , a welding tooling for metal plate parts, including a workbench and a welding robot arranged at the end of the workbench. The workbench includes a bearing component 2 sliding on the surface of the mounting frame 1 and a positioning component 5 for positioning the cabinet plate 11 and the middle beam 12. The bearing component 2 includes a slide plate 201 sliding inside the mounting frame 1 for moving the cabinet plate 11 towards the position of the welding robot and a bearing plate 202 arranged above the slide plate 201. An adjustment component for making the bearing plate 202 tilt diagonally or laterally is arranged between the slide plate 201 and the bearing plate 202. A material guide plate 10 is fixed at the position corresponding to the bearing plate 202 on the side of the mounting frame 1; The adjustment component includes a first support member 203 and a second support member 204 for supporting the bearing plate 202. The first support member 203 and the second support member 204 are located below the diagonal positions of the bearing plate 202, and the second support member 204 is close to the material guide plate 10. One end of the slide plate 201 close to the first support member 203 is fixedly assembled with a first electric push rod 205. The first electric push rod 205 is located in the middle of one end of the slide plate 201. One end of the slide plate 201 close to the second support member 204 is fixedly assembled with a second electric push rod 206. The second electric push rod 206 is located below the corner of the bearing plate 202 close to the second support member 204. The upper ends of the first electric push rod 205 and the second electric push rod 206 both abut against the lower surface of the bearing plate 202. One end of the slide plate 201 close to the second support member 204 is fixed with a support rod 207 and a first tension spring 208. The support rod 207 is located at the corner of the bearing plate 202 far from the second support member 204 and close to the material guide plate 10. The upper end of the support rod 207 abuts against the lower surface of the bearing plate 202. The first tension spring 208 is located between the second support member 204 and the support rod 207 and the upper end is fixed on the lower surface of the bearing plate 202; The first support member 203 includes a first sliding rod 2031 that slides vertically on the surface of the sliding plate 201 and two first springs 2032 sleeved on the surface of the first sliding rod 2031. The two first springs 2032 are respectively located above and below the sliding plate 201. The elastic force of the first spring 2032 located below is greater than that of the first spring 2032 located above. A first ball head 2033 is fixed to the upper end of the first sliding rod 2031. A first ball socket 2034 is provided on the surface of the first ball head 2033. A slider 2035 is fixed to the upper surface of the first ball socket 2034. The slider 2035 is trapezoidal. The first ball socket 2034 slides on the lower surface of the bearing plate 202 through the slider 2035. The upper end of the sliding rod is hinged to the lower surface of the bearing plate 202 through the first ball head 2033 and the first ball socket 2034. The second support member 204 includes a second sliding rod 2041 that slides vertically on the surface of the sliding plate 201 and two second springs 2042 sleeved on the surface of the second sliding rod 2041. The two second springs 2042 are respectively located above and below the sliding plate 201. The elastic force of the second spring 2042 located below is greater than that of the second spring 2042 located above. A second ball head 2043 is fixed to the upper end of the second sliding rod 2041. A second ball socket 2044 is provided on the surface of the second ball head 2043. A connecting rod 2045 is hinged to the upper surface of the second ball socket 2044. The upper end of the connecting rod 2045 is hinged to the lower surface of the bearing plate 202. The hinging direction of the connecting rod 2045 is set towards the direction of the first support member 203; A first positioning plate 2021 is fixed to a corner of the bearing plate 202 close to the first support member 203. The first positioning plate 2021 is L-shaped and located on the upper surface of the bearing plate 202. A grid-shaped rib 2022 is fixed to the upper surface of the bearing plate 202; A transmission assembly for driving the movement of the sliding plate 201 is provided on the surface of the mounting frame 1. The transmission assembly includes synchronous pulleys that rotate at both ends of the mounting frame 1. The two synchronous pulleys are both connected by a synchronous belt. One of the synchronous pulleys is driven to rotate by a driving motor. A connecting block is fixed to the lower surface of the sliding plate 201. The connecting block is fixed to the synchronous belt.

[0040] It is understandable that by setting the bearing plate 202, the cabinet plate 11 can be positioned and placed. The bearing plate 202 is driven by the sliding plate 201 to slide on the surface of the mounting frame 1, so as to facilitate moving the cabinet plate 11 below the positioning assembly 5, positioning and connecting the cabinet plate 11 with the middle beam 12 and moving it to the position of the welding robot for welding work. By setting the adjustment assembly, in the initial state, the bearing plate 202 is pulled downward by the first support member 203, the second support member 204 and the first tension spring 208, and horizontally supported by the first electric push rod 205, the second electric push rod 206 and the support rod 207. When the cabinet plate 11 drops onto the surface of the bearing plate 202, the second electric push rod 206 works to push one corner of the bearing plate 202 to rise. At this time, the bearing plate 202 rotates with the first ball head 2033 and the first ball socket 2034 of the first support member 203 as the center of the circle. The second support member 204 is pulled up and slides by the rising corner of the bearing plate 202. At the same time, the connecting rod 2045 automatically adjusts the support angle, so that the bearing plate 202 is diagonally inclined towards the direction of the first positioning plate 2021, and the cabinet plate 11 slides towards one corner of the first positioning plate 2021, so as to quickly perform preliminary positioning on the cabinet plate 11. By setting the grid-shaped convex strips 2022, the contact area between the cabinet plate 11 and the bearing plate 202 is reduced, so as to reduce the friction force and facilitate the sliding of the cabinet plate 11. After the preliminary positioning of the cabinet plate 11, the second electric push rod 206 is reset, and the bearing plate 202 is pulled down to the horizontal position under the action of the first support member 203, the second support member 204 and the first tension spring 208; when it is necessary to unload the welded cabinet plate 11, the first electric push rod 205 works to lift one end of the bearing plate 202 away from the guide plate 10. At this time, the first support member 203 is driven by the bearing plate 202 to slide up, and the angle is automatically adjusted through the first ball head 2033, the first ball socket 2034 and the slider 2035. The bearing plate 202 rotates with the second ball head 2043 and the second ball socket 2044 of the second support member 204 as the center of the circle. Under the pulling force of the first tension spring 208 and the second support member 204, it can be avoided that one end of the bearing plate 202 close to the guide plate 10 is lifted, so that the bearing plate 202 smoothly inclines to one side of the guide plate 10, so that the welded cabinet plate 11 slides through the guide plate 10 to the surface of the conveyor belt below the guide plate 10 for conveying, so as to achieve the purpose of automatic loading and unloading; by setting the first spring 2032 and the second spring 2042 at the positions of the first sliding rod 2031 and the second sliding rod 2041 above the sliding plate 201, the pulling forces of the first spring 2032 and the second spring 2042 located below the sliding plate 201 can be balanced, and it can be avoided that the pulling force is too large resulting in the angle imbalance of the bearing plate 202.

[0041] Specifically, a blanking component 4 is arranged above the positioning component 5 for placing the middle beam 12 on the surface of the positioning component 5. The blanking component 4 is located above the positioning component 5 and fixed on the surface of the connecting frame 8. The connecting frame 8 is fixed at the middle position of the mounting frame 1. The blanking component 4 includes a funnel 401 fixed on the surface of the connecting frame 8 and a guiding cylinder 402 fixed at the lower end of the funnel 401. The funnel 401 is communicated with the guiding cylinder 402. The inner wall of the guiding cylinder 402 is adapted to the middle beam 12. First clamping plates 403 are symmetrically arranged at the bottom of the guiding cylinder 402. The first clamping plates 403 are located in the middle of the guiding cylinder 402 to prevent the middle beam 12 from falling downward from the inside of the guiding cylinder 402. The upper ends of the first clamping plates 403 are fixed on both sides of the guiding cylinder 402 through fixing plates. The fixing plates are horizontally arranged. The lower ends of the first clamping plates 403 are obliquely arranged inside the guiding cylinder 402. A push plate 404 is horizontally fixed at the lower ends of the first clamping plates 403. The push plate 404 is located outside the guiding cylinder 402. Two push blocks 405 for pushing the push plate 404 are fixed on the upper surface of the positioning component 5. A plurality of third electric push rods 801 are fixed on the surface of the connecting frame 8. Electromagnets 802 for adsorbing the positioning component 5 are respectively fixed at the lower ends of the plurality of third electric push rods 801.

[0042] It can be understood that the middle beam 12 is conveyed into the funnel 401 through the conveying device. Under the action of the funnel 401, the middle beam 12 slides into the inside of the guiding cylinder 402. In the initial state, the two first clamping plates 403 extend into the inside of the guiding cylinder 402 to clamp the middle beam 12 and prevent the middle beam 12 from directly falling from the bottom of the guiding cylinder 402. When the third electric push rod 801 drives the positioning component 5 to move below the guiding cylinder 402 and dock with the guiding cylinder 402, the push blocks 405 on the surface of the positioning component 5 push the push plate 404, so that the push plate 404 drives the two first clamping plates 403 to release the middle beam 12, and the middle beam 12 falls onto the surface of the positioning component 5 to complete the handover.

[0043] Specifically, the positioning component 5 includes a frame body 501 and second positioning plates 502 fixed at the four corners of the frame body 501. The frame body 501 is in the shape of a Chinese character 'Ri'. Extension bodies are arranged at the positions in the middle of both ends of the frame body 501. Positioning grooves 505 for positioning the middle beam 12 are formed in the frame body 501 and the extension bodies. An inclined surface for facilitating the middle beam 12 to fall into the positioning groove 505 is arranged at the edge of the positioning groove 505. Notches for avoiding the inner frame of the cabinet board 11 are formed on the lower surfaces of the mutually remote ends of the two extension bodies. A plurality of positioning rods 503 cooperating with the second positioning plates 502 are fixed on the upper surface of the bearing plate 202. Permanent magnets 504 are arranged at the bottoms of the plurality of positioning rods 503. The magnetism of the permanent magnets 504 is less than that of the electromagnets 802. The two push blocks 405 are fixed on the upper surface of the frame body 501. The plurality of third electric push rods 801 are respectively located directly above the plurality of second positioning plates 502. The plurality of second positioning plates 502 are made of iron. A limiting component 506 for clamping the middle beam 12 is provided at the bottom of the frame body 501. The limiting component 506 is located on both sides of the positioning groove 505. The limiting component 506 includes a cavity 5061 opened at the bottom of the frame body 501 and a second clamping plate 5062 provided on the inner wall of the cavity 5061. The upper end of the second clamping plate 5062 is fixed to the inner wall of the cavity 5061, and the lower end of the second clamping plate 5062 is obliquely arranged in the positioning groove 505. An arc-shaped elastic pull plate 5063 and a support plate 5064 fixed to the lower surface of the elastic pull plate 5063 are arranged inside the cavity 5061. Both ends of the elastic pull plate 5063 are respectively fixed to the inner side of the second clamping plate 5062 and the inner wall of the cavity 5061. The elastic pull plate 5063 is used to push the lower end of the second clamping plate 5062 into the positioning groove 505, and the lower end of the support plate 5064 is lower than the lower surface of the frame body 501.

[0044] It can be understood that when the positioning component 5 is docked with the guiding cylinder 402, the positioning groove 505 corresponds to the guiding cylinder 402, so that the middle beam 12 drops into the positioning groove 505. In the initial state, the elastic pull plate 5063 pushes the second clamping plate 5062 to clamp the middle beam 12, preventing the middle beam 12 from directly falling out of the positioning groove 505. The frame body 501 is placed on the surface of the cabinet board 11 by driving the third electric push rod 801. The relative position between the frame body 501 and the cabinet board 11 is positioned through the cooperation of the second positioning plate 502 and the positioning rod 503. When the frame body 501 contacts the cabinet board 11, the support plate 5064 abuts against the cabinet board 11, driving the elastic pull plate 5063 to bend and deform, so that the elastic pull plate 5063 drives the second clamping plate 5062 to separate from the middle beam 12, causing the middle beam 12 to drop onto the surface of the cabinet board 11. At the same time, the positioning groove 505 continues to limit the middle beam 12, completing the automatic positioning of the cabinet board 11 and the middle beam 12.

[0045] Specifically, an offset component 7 for secondary positioning of the cabinet board 11 is provided at a corner of the frame body 501 corresponding to the first positioning plate 2021. The offset component 7 includes a column 701 fixed to the upper surface of the frame body 501 and two adjusting rods 703 arranged on both sides of the column 701 close to the inner border of the cabinet board 11. The lower ends of the two adjusting rods 703 are provided with rollers. A lifting block 702 slides on the surface of the column 701. The upper ends of the two adjusting rods 703 are hinged to adjacent sides of the lifting block 702 through a connecting shaft. A torsion spring 704 for driving the lower end of the adjusting rod 703 to rotate towards the column 701 is sleeved on the surface of the connecting shaft. The lower end of the adjusting rod 703 is lower than the lower surface of the frame body 501, and a second tension spring is fixed between the lifting block 702 and the frame body 501.

[0046] It is understandable that, since the cabinet panel 11 is not fixed after the initial positioning, the cabinet panel 11 may be offset when the load-bearing plate 202 drives the cabinet panel 11 to move, so the cabinet panel 11 needs to be positioned again. When the positioning assembly 5 moves downward, the two adjustment rods 703 first contact the cabinet panel 11. As the positioning assembly 5 continues to descend, the lower ends of the adjustment rods 703 move away from the column 701. When the adjustment rods 703 contact the inner frame of the cabinet panel 11, the cabinet panel 11 slides. Provide thrust, thereby pushing the cabinet panel 11 to slide in the direction of the first positioning plate 2021, and performing secondary positioning on the position of the cabinet panel 11. When the adjusting rod 703 pushes the cabinet panel 11 to contact the surface of the first positioning plate 2021, the frame 501 continues to move downward until it is pressed against the surface of the cabinet panel 11, and the two adjusting rods 703 can move upward on the surface of the column 701 through the lifting block 702 to provide sliding compensation. The second tension spring can drive the lifting block 702 to slide downward, providing a force for the tilt angle of the adjusting rod 703.

[0047] Specifically, a dredging component 6 for moving the inner middle beam 12 of the funnel 401 is provided on the top of the connecting frame 8. The dredging component 6 is located above the unloading component 4. The dredging component 6 includes a dredging plate 601 rotating on the surface of the connecting frame 8 and a turntable 602 rotating on the surface of the connecting frame 8. The turntable 602 is located above the rotating axis of the dredging plate 601. A fixing rod 603 is eccentrically fixed on the surface of the turntable 602. An elongated hole 604 matching the fixing rod 603 is provided on the surface of the dredging plate 601. The turntable 602 is driven to rotate by a driving motor. The lower end of the dredging plate 601 passes through the connection between the funnel 401 and the guide cylinder 402 during the swinging process.

[0048] It is understandable that when the middle beam 12 falls into the funnel 401, it may be stuck at the entrance of the guide cylinder 402 in a diamond shape, and the fixing rod 603 is driven to rotate through the turntable 602. The fixing rod 603 drives the upper end of the dredging plate 601 to swing back and forth through the long hole 604, thereby causing the lower end of the dredging plate 601 to swing back and forth. During the swinging process, the lower end of the dredging plate 601 moves the middle beam 12 to adjust its posture, so that the middle beam 12 can smoothly fall into the inside of the guide cylinder 402 to avoid blockage.

[0049] Specifically, two guide rails 3 are symmetrically fixed on the upper surface of the mounting frame 1, and one end of the entrance of the guide rail 3 is located between the side of the connecting frame 8 facing the guide plate 10 and the side of the guide plate 10 facing the connecting frame 8. A plurality of balls 301 cooperating with the guide rail 3 are symmetrically arranged on the lower surface of the supporting plate 202. The height of the guide rail 3 is 5-10 mm higher than the bottom of the ball 301, and one end of the entrance of the guide rail 3 is an arc that bends downward.

[0050] It can be understood that since the adjustment components on the surface of the skateboard 201 affect the stability of the bearing plate 202, in order to avoid the position or angle deviation of the bearing plate 202 during welding, therefore, by setting the guide rail 3 and the ball 301, when the skateboard 201 drives the bearing plate 202 to slide towards the welding robot, it slides onto the surface of the guide rail 3 through the ball 301. At the same time, the guide rail 3 jacks up the bearing plate 202, and the first support member 203, the second support member 204 and the first tension spring 208 provide a downward pressure on the bearing plate 202, so that the bearing plate 202 acts completely on the surface of the guide rail 3 through a plurality of balls 301, thereby improving the stability of the bearing plate 202.

[0051] Specifically, two pressing plates 9 are symmetrically fixed inside the connecting frame 8, and the heights of the two pressing plates 9 are higher than the height of the upper surface of the bearing plate 202.

[0052] It can be understood that since the positioning component 5 is adsorbed on the surface of the bearing plate 202 by a plurality of permanent magnets 504, the third electric push rod 801 separates the positioning component 5 from the bearing plate 202 by the suction force of the electromagnet 802, and the bottom of the bearing plate 202 is slidably arranged on the surface of the skateboard 201. In order to prevent the bearing plate 202 from rising with the positioning component 5, the pressing plate 9 is provided. When the bearing plate 202 slides within the range of the connecting frame 8, the pressing plate 9 is located above the bearing plate 202. When the third electric push rod 801 separates the positioning component 5 from the bearing plate 202, the pressing plate 9 presses the bearing plate 202 to prevent the bearing plate 202 from rising with the positioning component 5.

[0053] In the present invention, the cabinet panel 11 is conveyed to the surface of the bearing plate 202 by an intermittent conveying device, so that the bearing plate 202 is tilted at an angle towards the first positioning plate 2021 through an adjustment assembly. The cabinet panel 11 is preliminarily positioned by the first positioning plate 2021, and then the bearing plate 202 is restored to the horizontal position. The synchronous belt and synchronous pulley drive the sliding plate 201 and the bearing plate 202 to slide on the surface of the mounting frame 1 within the range of the connecting frame 8. The bearing plate 202 slides on the guide rail 3 through a plurality of balls 301. The guide rail 3 limits the bearing plate 202 and improves its stability at the same time. The third electric push rod 801 drives the positioning assembly 5 to descend. Through the cooperation of the second positioning plate 502 and the positioning rod 503, the relative positions of the frame body 501 and the cabinet panel 11 are positioned. Then, the two adjusting rods 703 of the offset assembly 7 perform secondary positioning on the cabinet panel 11. After the positioning assembly 5 is attached to the cabinet panel 11, the positioning assembly 5 is fixed by the permanent magnet 504. During the process of the positioning assembly 5 being attached to the cabinet panel 11, the support plate 5064 abuts against the cabinet panel 11, driving the elastic tension plate 5063 to bend and deform. The elastic tension plate 5063 drives the second clamping plate 5062 to separate from the middle beam 12, causing the middle beam 12 to fall onto the surface of the cabinet panel 11. At the same time, the positioning groove 505 continues to limit the middle beam 12, completing the automatic positioning of the cabinet panel 11 and the middle beam 12. Then, the positioned cabinet panel 11 and the middle beam 12 are moved to the front of the welding robot by the sliding plate 201 for welding work. At the same time, the middle beam 12 is conveyed into the funnel 401 by the intermittent conveying device, and the middle beam 12 slides into the inside of the guiding cylinder 402. The dredging assembly 6 can prevent the middle beam 12 from being stuck at the entrance position of the guiding cylinder 402. The first clamping plate 403 clamps the middle beam 12 to prevent the middle beam 12 from directly falling from the bottom of the guiding cylinder 402, so that the middle beam 12 is temporarily stored in the guiding cylinder 402. After welding, the cabinet panel 11 is moved again within the range of the connecting frame 8, and the positioning assembly 5 is separated from the bearing plate 202 by the third electric push rod 801 and the electromagnet 802. When the positioning assembly 5 is docked with the guiding cylinder 402, the positioning groove 505 corresponds to the guiding cylinder 402. The first clamping plate 403 releases the middle beam 12 through the push block 405 and the push plate 404, causing the middle beam 12 to fall into the positioning groove 505. In the initial state, the elastic tension plate 5063 pushes the second clamping plate 5062 to clamp the middle beam 12 to prevent the middle beam 12 from directly falling from the positioning groove 505, so that the middle beam 12 is stored in the positioning groove 505 for repositioning. The sliding plate 201 drives the bearing plate 202 back to the position corresponding to the guiding plate 10, and the bearing plate 202 is tilted towards the guiding plate 10 through the adjustment assembly, so that the welded cabinet panel 11 slides onto the conveying device through the guiding plate 10. The positioning rods 503 on both sides of the cabinet panel 11 can prevent the cabinet panel 11 from deviating from the guiding plate 10 during the sliding process;The cooperation between the positioning component 5 and the blanking component 4 can achieve the purpose of synchronous feeding. During the process of the positioning component 5 rising or falling, the feeding, positioning, and fixing of the middle beam 12 are completed. At the same time, through the cooperation of the offset component 7, the secondary positioning of the cabinet panel 11 is synchronously achieved, and the full-automatic welding of the cabinet panel 11 is realized in the above manner, improving the degree of automation.
