Description

Technical Field

[0001] This invention relates to the technical field of welding robots, and in particular to an automatic welding robot for automotive condenser manifolds. Background Technology

[0002] The main function of the manifold in an automotive air conditioning condenser is to collect the refrigerant from the branch pipes. In condenser design, to improve heat dissipation and reduce pipe resistance, it is typically designed with multiple branched cooling channels. After cooling, these branched refrigerant channels converge into a single manifold, and then flow into the next system component.

[0003] In the prior art, patent application number 201520329991.8 discloses a welding fixture for a manifold assembly, comprising: a platform with a support column for supporting the main manifold on its end face; and a bracket on the platform, wherein a support block is provided on the bracket to support a branch manifold inserted into the main manifold. When assembling the manifold assembly, the platform of the welding fixture of this invention is placed on a rotating welding table, then the main manifold is placed on the support column, and then the branch manifold is inserted into the furnace tube of the main unit at a specific position and held stationary by the support block before welding begins. Since the welding fixture of this invention can replace manual operation, and the angle of the branch manifold remains essentially unchanged during welding due to the cooperation of the support block and the support column, the welding efficiency of the manifold assembly can be improved.

[0004] During use, it was found that when welding the manifold to the external threaded connector, the manifold needs to be pre-drilled. When welding the manifold to the external threaded connector, the connecting hole of the manifold needs to be guided and aligned so that the opening and the external threaded connector are axially aligned. The operation is not convenient and the welding efficiency is low. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an automated welding robot for automotive condenser manifolds that improves welding efficiency.

[0006] This invention discloses an automatic welding robot for automotive condenser manifolds, comprising a base plate, a welding robot, a turntable, a worktable, support rods, a placement slot, and a support frame. A support frame is mounted on the top of the base plate, and the welding robot is mounted on the top of the support frame. A support rod is mounted on the bottom of the turntable, and a placement slot is mounted on the top of the turntable. A through-hole is located on the bottom of the turntable, communicating with the placement slot. Multiple sets of support rods are mounted on the bottom of the worktable, and a circular groove is located on the top of the worktable. The robot also includes a clamping assembly, a driving assembly, and a drilling positioning assembly. The clamping assembly is located in the placement slot, the driving assembly is located in the circular groove, and the multiple sets of support rods are mounted on the driving assembly. A drilling positioning assembly is located on the top of the worktable. In use, the manifold is placed in the placement slot, and the external threaded connector is placed on the drilling positioning assembly. Then, the clamping assembly is used to clamp and fix the manifold on both ends of the placement slot. Next, the drilling positioning assembly is used to drill a hole in the manifold in the placement slot. After the hole is drilled, the external threaded connector is aligned with the hole using the drilling positioning assembly. The welding robot welds the contact part between the manifold and the external threaded connector. After welding on one side is completed, the drive assembly drives the turntable to rotate 180 degrees, thereby rotating the manifold and the external threaded connector. This brings the unwelded contact part of the manifold and the external threaded connector closer to the welding robot, allowing the welding robot to weld the manifold and the external threaded connector, thus improving welding efficiency.

[0007] Preferably, the clamping assembly includes a vertical plate, a square frame, a partition, an opening, a guide bar, a main rack, a first motor, a first rotating shaft, a main gear, a connecting rod, a clamping plate, and a moving rod. Two sets of vertical plates are provided at the bottom of the turntable, and a square frame is provided at the center of the bottom of the turntable. A partition is provided inside the square frame, dividing the interior of the square frame into two sets of accommodating cavities. An opening is provided in the middle of the partition, communicating with the two sets of accommodating cavities. A first motor is provided at the bottom of the square frame, and a first rotating shaft is rotatably mounted in the opening. The output end of the first motor is connected to one end of the first rotating shaft, and a main gear is mounted on the first rotating shaft. A set of moving rods is slidably arranged in each set of accommodating cavities. A slot is provided at the end of each set of moving rods that is close to each other, and a set of main racks is installed in each slot. The main gear meshes with the two sets of main racks. Each set of guide bars passes through a set of moving rods. It is slidably connected to the moving rod, and the two sets of light rods are fixedly installed between the two sets of upright plates. Each set of moving rods has a set of upright plates at its top, and the top of each set of connecting rods extends through the opening into the placement slot. Each set of connecting rods has a set of clamping plates at its top. The manifold is placed in the placement slot, and then the No. 1 motor is started, which causes the No. 1 rotating shaft to drive the main gear to rotate in the opening. Since the main gear meshes with the two sets of main racks, the two sets of main racks drive the corresponding moving rods to move in a mirror image in the two sets of accommodating cavities. When the two sets of moving rods move in a mirror image, the two sets of connecting rods corresponding to the moving rods drive the corresponding clamping plates to move in a mirror image in the placement slot, so that the two sets of clamping plates clamp and fix the manifold at both ends in the placement slot, and at the same time perform the centering operation on the manifold.

[0008] Preferably, the drive assembly includes a ring track, rollers, a second motor, a second rotating shaft, and a circular plate. The ring track is arranged in the circular groove, the second motor is located at the bottom of the worktable, and the output end of the second motor is connected to the second rotating shaft. The top end of the second rotating shaft extends into the circular groove and connects to the center of the bottom end of the circular plate. Multiple sets of rollers are arranged circumferentially around the center of the circular plate at its bottom end. All sets of rollers are slidably mounted on the ring track. The outer side wall of the circular plate contacts the inner side wall of the circular groove, and the top end of the circular plate is connected to the bottom end of multiple sets of support rods. When it is necessary to adjust the turntable by 180 degrees, the second motor is started, thereby causing the second rotating shaft to drive the circular plate to rotate. Since the multiple sets of rollers are slidably connected to the ring track, the circular plate rotates smoothly, improving the stability of the rotation.

[0009] Preferably, the drilling positioning assembly includes a column, a crossbeam, a first servo electric cylinder, a cylinder, a first groove, a first rack, a second groove, a third motor, a third rotating shaft, a drill, a cylinder, a second rack, a slide rod, a limit block, a transmission assembly, and a positioning assembly. Two sets of columns are installed at the top of the worktable, with the tops of both sets of columns connected to the bottom of the crossbeam. A first servo electric cylinder is installed at the center of the bottom of the crossbeam. A cylinder is installed at the bottom moving end of the first servo electric cylinder. Two sets of first grooves are symmetrically arranged on the outer wall of the cylinder, and a first rack is installed in each set of first grooves. The bottom of the cylinder is equipped with... There is a second groove, in which a third motor is installed. The output end of the third motor has a third rotating shaft, and the bottom end of the third rotating shaft has a punch. A cylindrical body is fitted onto the outer side of the cylinder. Two sets of second-order racks are symmetrically arranged on the inner side of the cylindrical body. Two sets of sliding rods are located at the top of the cylindrical body, extending to the top of the crossbeam. The sliding rods are slidably connected to the crossbeam, and the top of each set of sliding rods is connected to the bottom end of a limiting block. Two sets of transmission components are located at the bottom end of the crossbeam, and a positioning component is installed on the cylindrical body. In use, the external threaded connector is placed inside the cylindrical body, and the positioning component is used to fix the external threaded connector. The inner diameter of the external threaded connector is larger than the outer diameter of the cylinder. Operating the first servo electric cylinder extends, causing the cylinder to move downwards. Simultaneously, both sets of first-order racks move downwards in sync. Through corresponding transmission components, the two sets of second-order racks move upwards, causing the second-order racks, in conjunction with the two sets of sliding rods, to drive the cylinder upwards. This further causes the cylinder, through the positioning components, to drive the external threaded connector upwards. Simultaneously, the cylinder, the third motor, the third rotating shaft, and the punch pass through the inside of the external threaded tube. Starting the third motor causes the third rotating shaft to drive the punch to rotate rapidly, further aligning the column with... The manifold, fixed in the slot, is drilled. After drilling, the No. 1 servo electric cylinder is shortened, causing the cylinder to move upward along with two sets of No. 1 racks, No. 3 motor, No. 3 rotating shaft, and the drill. Simultaneously, the two sets of No. 1 racks drive the cylinder downward through the transmission assembly, further aligning the external threaded joint with the drilled hole through the positioning assembly. The external threaded joint makes seamless contact with the manifold. Then, the welding robot welds the contact part of the manifold and the external threaded joint, realizing the drilling of the manifold and the automatic alignment of the external threaded joint with the drilled hole, thus improving welding efficiency.

[0010] Preferably, the transmission assembly includes a vertical plate, a rotating shaft, and transmission gears. The bottom end of the crossbeam is provided with a vertical plate, and a rotating shaft is rotatably mounted on the vertical plate. Transmission gears are mounted on the rotating shaft, and the transmission gears mesh with racks number one and two respectively. When rack number one moves downward, the transmission gears rotate accordingly, thereby causing rack number two to move upward, thus realizing the mirror movement of racks number one and two.

[0011] Preferably, the positioning component includes a second servo electric cylinder, a clamping plate, an arc-shaped opening, and guide wheels. Two sets of second servo electric cylinders are symmetrically arranged on the outer wall of the cylinder. The moving end of each set of second servo electric cylinders extends to the inner side of the cylinder and is respectively provided with a set of clamping plates. An arc-shaped opening is provided at the end of the two sets of clamping plates that are close to each other. A guide wheel is provided in each arc-shaped opening. When the external threaded joint is placed on the inner side of the cylinder, the two sets of second servo electric cylinders are operated to extend synchronously, so that the two sets of clamping plates clamp and fix the outer wall of the external threaded joint through the multiple sets of guide wheels in the arc-shaped opening. The external threaded joint can rotate but cannot move up and down under the support of the multiple sets of guide wheels. When the cylinder moves downward, the multiple sets of guide wheels drive the external threaded joint to move downward. When the bottom end of the external threaded joint does not match the opening of the manifold, the external threaded joint can make adaptive horizontal angle adjustments with the cooperation of the multiple sets of guide wheels to improve flexibility.

[0012] Preferably, it also includes a third servo electric cylinder, a brake block, and a mounting plate. The mounting plate is provided at the top of the worktable, and the third servo electric cylinder is installed at the end of the mounting plate away from the circular plate. The moving end of the third servo electric cylinder passes through the mounting plate and is provided with a brake block. When it is necessary to position the turntable, the third servo electric cylinder is activated to extend, thereby causing the brake block to press against the outer wall of the circular plate, thereby indirectly completing the braking of the turntable and improving its stability.

[0013] Preferably, the base plate also includes adjustable feet, and the bottom end of the base plate is provided with multiple sets of adjustable feet; the multiple sets of adjustable feet cooperate with each other to provide stable support for the base plate and improve stability.

[0014] Preferably, it also includes a guide rod, and two sets of guide rods are provided at the end of the brake block away from the circular plate. The two sets of guide rods pass through the mounting plate and are slidably connected to the mounting plate. The No. 3 servo electric cylinder moves the brake block stably with the cooperation of the two sets of guide rods, thereby improving the movement stability.

[0015] Preferably, a reinforcing plate is provided between the column and the beam; the column and the beam are strengthened by the reinforcing plate to improve the connection strength.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In use, the manifold is placed in the placement slot, and the external threaded connector is placed on the drilling positioning assembly. Then, the clamping assembly is used to clamp and fix the manifold on both ends of the placement slot. After that, the drilling positioning assembly is used to open a hole in the manifold in the placement slot. After the hole is opened, the external threaded connector is aligned with the hole using the drilling positioning assembly. The welding robot welds the contact part between the manifold and the external threaded connector. After one side is welded, the drive assembly drives the turntable to rotate 180 degrees, thereby rotating the manifold and the external threaded connector. This allows the unwelded contact part of the manifold and the external threaded connector to approach the welding robot, thereby allowing the welding robot to weld the manifold and the external threaded connector, thus improving welding efficiency.

The outer side wall of the circular plate 305 contacts the inner side wall of the circular groove. The top end of the circular plate 305 is connected to the bottom end of multiple sets of support rods 106.

[0043] like Figure 1 , Figure 2 , Figure 5 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 19 and Figure 20As shown, the drilling positioning assembly includes a column 401, a crossbeam 402, a first servo electric cylinder 403, a cylinder 404, a first groove 405, a first rack 406, a second groove 407, a third motor 408, a third rotating shaft 409, a drill 410, a cylinder 411, a second rack 412, a slide rod 413, a limit block 414, a transmission assembly, and a positioning assembly. Two sets of columns 401 are installed at the top of the worktable 104, and the tops of both sets of columns 401 are connected to the bottom end of the crossbeam 402. A first servo electric cylinder 403 is installed at the center of the bottom end of the crossbeam 402. A cylinder 404 is installed at the bottom moving end of the first servo electric cylinder 403. Two sets of first grooves 405 are symmetrically arranged on the outer wall of the cylinder 404. Each set of first grooves 405... A set of first racks 406 is provided in the middle. A second groove 407 is provided at the bottom of the cylinder 404. A third motor 408 is installed in the second groove 407. A third rotating shaft 409 is provided at the output end of the third motor 408. A punch 410 is installed at the bottom end of the third rotating shaft 409. A cylinder 411 is fitted on the outside of the cylinder 404. Two sets of second racks 412 are symmetrically arranged on the inside of the cylinder 411. Two sets of sliding rods 413 are provided at the top of the cylinder 411. The tops of the two sets of sliding rods 413 extend to the top of the crossbeam 402. The sliding rods 413 are slidably connected to the crossbeam 402. The tops of the two sets of sliding rods 413 are connected to the bottom end of the limiting block 414. Two sets of transmission components are provided at the bottom end of the crossbeam 402. A positioning component is provided on the cylinder 411.

[0044] like Figure 14 , Figure 15 , Figure 19 and Figure 20As shown, the transmission assembly includes a vertical plate 501, a rotating shaft 502, and a transmission gear 503. The bottom end of the crossbeam 402 is provided with the vertical plate 501, and the rotating shaft 502 is rotatably mounted on the vertical plate 501. The transmission gear 503 is mounted on the rotating shaft 502, and the transmission gear 503 meshes with the first rack 406 and the second rack 412 respectively. The manifold is placed in the placement slot 107, and then the first motor 207 is started, causing the first rotating shaft 208 to drive the main gear 209 to rotate in the opening 204. Since the main gear 209 meshes with the two sets of main racks 206 respectively, the two sets of main racks 206 respectively drive the corresponding moving rods 212 to move in mirror images within the two sets of accommodating cavities. When the two sets of moving rods 212 move in a mirror image, the two sets of connecting rods 210 corresponding to the moving rods 212 drive the corresponding clamping plates 211 to move in a mirror image within the placement slot 107. This causes the two sets of clamping plates 211 to clamp and fix the two ends of the manifold in the placement slot 107, and simultaneously perform a centering operation on the manifold. In use, the external threaded connector is placed inside the cylinder 411, and the positioning component is used to fix the external threaded connector. The inner diameter of the external threaded connector is larger than the outer diameter of the cylinder 404. The first servo electric cylinder 403 is extended, causing the cylinder 404 to move downward. At the same time, the two sets of first racks 406 move downward synchronously. The two sets of first racks 406 are connected by corresponding transmissions. The components cause the two sets of second racks 412 to move upward, which in turn causes the second racks 412 to drive the cylinder 411 to move upward with the cooperation of the two sets of slide rods 413. The cylinder 411 then drives the external threaded joint upward through the positioning components. Simultaneously, the cylinder 404, the third motor 408, the third rotating shaft 409, and the punch 410 pass through the inside of the external threaded tube. The third motor 408 is started, causing the third rotating shaft 409 to drive the punch 410 to rotate rapidly. This further causes the column 401 to perform a hole-opening operation on the collection pipe fixed in the slot 107. After the hole-opening is completed, the first servo electric cylinder 403 is shortened, causing the cylinder 404 to drive the two sets of first racks 406 and the third motor... 408, the third rotating shaft 409, and the punch 410 move upwards, while the two sets of first racks 406 drive the cylinder 411 downwards through the transmission assembly, further enabling the cylinder 411 to drive the external threaded joint to coincide and align with the opening through the positioning assembly, so that the external threaded joint makes seamless contact with the manifold. Then, the welding robot 102 is operated to weld the contact part of the manifold and the external threaded joint, realizing the punching of the manifold and the automatic alignment of the external threaded joint with the opening. After the welding on one side is completed, the second motor 303 is started, so that the second rotating shaft 304 drives the circular plate 305 to rotate. Since multiple sets of rollers 302 are slidably connected to the annular track 301, the circular plate 305 rotates smoothly.

The sliding rods 413 are slidably connected to the crossbeam 402. The tops of the two sets of sliding rods 413 are connected to the bottom end of the limiting block 414. Two sets of transmission components are provided at the bottom end of the crossbeam 402. A positioning component is provided on the cylinder 411.

[0050] like Figure 14 , Figure 15 , Figure 19 and Figure 20 As shown, the transmission assembly includes a vertical plate 501, a rotating shaft 502, and a transmission gear 503. The bottom end of the crossbeam 402 is provided with a vertical plate 501, and a rotating shaft 502 is rotatably mounted on the vertical plate 501. A transmission gear 503 is mounted on the rotating shaft 502, and the transmission gear 503 meshes with a first rack 406 and a second rack 412 respectively.

[0051] like Figure 16 , Figure 17 and Figure 18 As shown, the positioning assembly includes a second servo electric cylinder 601, a clamping plate 602, an arc-shaped opening 603, and a guide wheel 604. Two sets of second servo electric cylinders 601 are symmetrically arranged on the outer side wall of the cylinder 411. The moving end of each set of second servo electric cylinders 601 extends to the inner side of the cylinder 411 and is respectively provided with a set of clamping plates 602. An arc-shaped opening 603 is respectively provided at the end of the two sets of clamping plates 602 that are close to each other.

The moving end of the third servo electric cylinder 701 passes through the mounting plate 703 and is provided with a brake block 702.

[0053] like Figure 2As shown, it also includes adjustable feet 110 and light rods 704. The bottom end of the base plate 101 is provided with multiple sets of adjustable feet 110. The brake block 702 is provided with two sets of light rods 704 at the end away from the circular plate 305. The two sets of light rods 704 pass through the mounting plate 703 and are slidably connected to the mounting plate 703.The manifold is placed in the placement slot 107, and then the first motor 207 is started, causing the first rotating shaft 208 to drive the main gear 209 to rotate in the opening 204. Since the main gear 209 meshes with two sets of main racks 206, the two sets of main racks 206 drive the corresponding moving rods 212 to move in mirror image within the two sets of accommodating cavities. When the two sets of moving rods 212 move in mirror image, the two sets of connecting rods 210 corresponding to the moving rods 212 drive the corresponding clamping plates 211 to move in mirror image within the placement slot 107, thereby clamping and fixing the manifold at both ends in the placement slot 107 and centering the manifold. In use, the external threaded connection is... The head is placed inside the cylinder 411. Two sets of second-generation servo electric cylinders 601 extend synchronously, causing the two sets of clamping plates 602 to clamp and fix the outer wall of the external threaded joint through multiple sets of guide wheels 604 in the arc-shaped opening 603. The external threaded joint can rotate but cannot move up or down under the support of the guide wheels 604. The inner diameter of the external threaded joint is larger than the outer diameter of the cylinder 404. The first-generation servo electric cylinder 403 extends, causing the cylinder 404 to move downwards. Simultaneously, the two sets of first-generation racks 406 move downwards synchronously. Through corresponding transmission components, the two sets of second-generation racks 412 move upwards, causing the second-generation racks 412 to drive the cylinder 411 upwards in conjunction with the two sets of sliding rods 413. The movement further causes the cylinder 411 to move upward via the positioning assembly, driving the external threaded joint upward. Simultaneously, the cylinder 404, motor 408 (number three), shaft 409 (number three), and punch 410 pass through the inside of the external threaded tube. Motor 408 is activated, causing shaft 409 to drive punch 410 to rotate rapidly, further causing column 401 to perform an opening operation on the manifold fixed in slot 107. After opening, servo electric cylinder 403 is shortened, causing cylinder 404 to drive two sets of racks 406 (number one), motor 408 (number three), shaft 409 (number three), and punch 410 upward. Simultaneously, the two sets of racks 406 (number one) drive cylinder 411 downward via the transmission assembly, further causing cylinder 411 to move downward. 1. The positioning component drives the external threaded connector to align with the opening, achieving seamless contact between the external threaded connector and the manifold. Then, the welding robot 102 welds the contact area between the manifold and the external threaded connector, realizing the automatic alignment of the manifold hole and the external threaded connector with the opening. After welding on one side is completed, the second motor 303 is started, causing the second rotating shaft 304 to rotate the circular plate 305. Because multiple sets of rollers 302 are slidably connected to the annular track 301, the circular plate 305 rotates smoothly. When positioning of the turntable 103 is required, the third servo electric cylinder 701 extends, causing the brake block 702 to press against the outer wall of the circular plate 305, thus indirectly braking the turntable 103.
