[0002] The welding technology of new energy battery trays is developing rapidly.

[0017] A further improvement based on the above technical solution is that a connecting plate is locked and connected on one side of the three-way pipe, and transverse guide rods are respectively fixed on the front and rear sides of the connecting plate. The two transverse guide rods slide through the middle of the two vertical frames respectively, and two relative transverse telescopic rods are installed on the mounting seat, and the telescopic ends of the two relative transverse telescopic rods are respectively locked and connected to the connecting plates of the two three-way pipes.

[0018] A further improvement based on the above technical solution is that a connecting frame is fixedly provided on the upper side of the three-way pipe, and the connecting frame is laterally slidable and penetrates a plurality of rectangular sliding rods, and a top plate is installed on one end of the rectangular sliding rod facing the fixed tray, and the rectangular sliding rod sleeve is provided with a return spring, and the top plate is elastically connected to the connecting frame through the return spring.

[0019] A further improvement based on the above technical solution is that the driving assembly includes a tooth row fixedly mounted on the left and right sides of the sliding base, and a slide groove opened in the middle of the conveying base, the sliding base is slidably arranged in the middle of the slide groove, a transmission tooth belt is longitudinally mounted on one side of the conveying base, wherein a transmission motor for driving the transmission tooth belt to rotate is mounted on one side of the conveying base, the transmission tooth belt is meshed with the tooth row for transmission, and is used to drive the conveying platform to slide and move in the slide groove;

[0020] A plurality of horizontally arranged rotating bearings are rotatably installed on the left and right sides of the bottom of the sliding base plate, and the side surfaces of the rotating bearings are in rolling contact with the side surfaces of the slide groove. A lower ball is rotatably embedded in the bottom of the rotating bearing and is in rolling contact with the lower side of the slide groove through the lower ball.

[0021] The invention also includes a working method of a welding intelligent workstation for a new energy battery pallet: placing the pallet on a conveyor table, placing the pallet on the upper ball bearings protruding in the middle of four jacking pipes, and clamping the pallet through the clamping components on the front and rear sides of the conveyor table; at this time, the conveyor table is driven and transported to the work station of the mounting seat through the driving component on the conveying base, that is, between two relative auxiliary fixing frames, within the welding range of two intelligent welding manipulators; at this time, the two ends of the three-way pipes arranged on the two relative auxiliary fixing frames correspond to the left and right sides of the pallet; when the two three-way pipes are relatively displaced, the pallet can be pushed to correct the displacement position on the upper ball bearings, and the correction After completion, the clamping assembly is released, and the lifting support plate rises upward, so that the tray falls on the upper side of the four lifting pipes and is lifted up, while the support rod and the top of the upper ball block the inner tube cavity at the bottom of the lifting pipe, leaving only the socket connected to the inner tube cavity on the upper side of the lifting pipe. After the lifting support plate is raised, the socket corresponds to the two ends of the two tees. Under the secondary relative displacement activity of the two tees, the opposite ends of the tees are respectively inserted into the sockets to firmly tighten the lifting support plate. At the same time, the four lifting pipes generate adsorption force under the action of the suction pump, thereby adsorbing and fixing the tray, allowing the industrial visual inspection camera to cooperate with the intelligent welding manipulator to perform welding work.

[0022] By adopting the above technical solution, the present invention has the following advantages compared with the existing technology:

[0023] The present invention supports each tray separately through each conveying platform, so that it is convenient to maintain or replace the conveying platform separately in the later stage. At the same time, when the lifting support plate on the conveying platform is lowered to the lowest state, the upper ball is higher than the top of the jacking pipe, and the tray is placed on the upper ball for support. At this time, the conical top plugs at both ends of the three-way pipe correspond to the side of the tray. Therefore, when the conical top plugs of the two auxiliary fixing frames are displaced relatively, not only can the tray be pushed to the upper ball sliding correction position, but also the upper ball setting has the advantage of reducing the friction and wear on the tray when correcting the position, and the correction is safer and smoother.

[0024] Secondly, when the lifting support plate rises, the upper ball is separated from the bottom of the tray, and the four lifting pipe fittings lift the tray up. At this time, the support plug rod seals the inner tube cavity at the bottom of the lifting pipe fitting, so that the conical top plugs at both ends of the three-way pipe of the two auxiliary fixing frames are adapted to the corresponding sockets on the side of the lifting support plate. Therefore, the relative displacement of the three-way pipes of the two auxiliary fixing frames can allow the conical top plugs at both ends of the three-way pipe to be inserted into the sockets respectively, and connected with the lifting pipe fittings. Under the action of the suction pump, the lifting pipe fittings generate negative pressure to suck the tray tightly and clamp the lifting support plate firmly. That is to say, the conical top plug inserted into the socket at this time can not only position and clamp the lifting support plate and the lower part to prevent the shaking of the entire conveying platform, but also cooperate with the suction pump and the lifting pipe fittings to adsorb and fix the tray held up by the lifting pipe fittings;

[0025] In order to further improve the stabilizing effect of the tray on the jacking pipe, a connecting frame is also provided on the upper side of the three-way pipe, and the connecting frame is connected to the top plate through a return spring. Therefore, when the two three-way pipes are relatively displaced, not only can the conical top plugs at both ends of the three-way pipe be respectively inserted into the insertion holes to generate a stabilizing effect, but the top plate can also use the elastic force of the return spring to relatively flexibly tighten and fix the tray adsorbed on the jacking pipe to prevent it from shifting to the left and right positions; at the same time, telescopic tightening rods are also provided on the two auxiliary fixing frames, which can tighten the left and right sides of the tray downward to play an upper and lower limit role, further improving the stability of the tray, wherein the infrared rangefinder can detect the thickness and position of the tray, so that the telescopic tightening rod can more accurately extend and tighten the tray to avoid deformation of the tray caused by excessive extension force;

[0026] The present invention drives the conveying platform to slide on the slide groove to convey the tray through the driving component on the conveying base. The driving component mainly drives the tooth row of the conveying platform through the transmission gear belt, so as to accurately and stably drive the conveying platform to the welding work place, and cooperates with the use of the rotating bearing, the lower ball and the slide groove to make the conveying platform slide on the slide groove more smoothly.

[0027] When the conveyor slides, the clamping components on the front and rear sides can respectively press against the front and rear sides of the tray through the rotating plate and the abutting wheels to prevent it from falling off during the conveying process and improve the stability of use.

DETAILED DESCRIPTION

[0041] 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.

[0042] like Figure 1-11As shown, the present invention provides a technical solution of a welding intelligent workstation for a new energy battery pallet: it includes a pallet 10, a dustproof box cover 1, a mounting seat 2 and two intelligent welding manipulators 5 arranged inside the dustproof box cover 1. The dustproof box cover 1 is designed to protect the welding process from interference from external dust and ensure the cleanliness of the welding environment. Two intelligent welding manipulators 5 are installed on the mounting seat 2, which can be used for alternating welding or synchronous welding according to usage requirements. The mounting seat 2 is equipped with two front and rear slides 7, and the sliding ends of the front and rear slides 7 are equipped with industrial visual inspection cameras 71. The industrial visual inspection camera 71 is used to detect and view the welding condition of the pallet 10 and cooperate with the intelligent welding manipulator 5 for welding. A conveying base 3 is installed in the middle of the mounting seat 2, and the two ends of the conveying base 3 are distributed through the front and rear sides of the dustproof box cover 1. A plurality of conveying platforms 4 for placing the pallet 10 are slidably arranged on the conveying base 3, and a driving component for driving the conveying platform 4 to slide is installed on one side of the conveying base 3. Therefore, specifically, the driving component includes a fixedly mounted on the slide The tooth rows 42 on the left and right sides of the movable base plate 41, and the slide groove 31 opened in the middle of the conveying base 3, the sliding base plate 41 is slidably arranged in the middle of the slide groove 31, and a transmission toothed belt 32 is longitudinally installed on one side of the conveying base 3, wherein a transmission motor 33 for driving the transmission toothed belt 32 to rotate is installed on one side of the conveying base 3, and the transmission motor 33 can accurately adjust the moving speed and displacement of the conveying platform 4 according to production requirements. For example, in different welding processes, the conveying speed of the pallet 10 can be adjusted according to the welding speed, so that the entire welding process is efficient and stable; the transmission toothed belt 32 is meshed with the tooth row 42 for transmission, which is used to drive the conveying platform 4 to slide and displace in the slide groove 31. This transmission method can accurately control the sliding displacement of the conveying platform 4 in the slide groove 31. Since the meshing between the teeth has a fixed spacing and matching relationship, high-precision positioning can be achieved. For example, when welding a new energy battery pallet, the pallet 10 can be accurately transported to the working area of ​​the welding manipulator 5 to ensure the accurate position of the welding point, thereby improving the welding quality.

[0043] The left and right sides of the bottom of the sliding base plate 41 are respectively rotatably installed with a plurality of horizontally arranged rotating bearings 46, and the side surfaces of the rotating bearings 46 are in rolling contact with the side surfaces of the slide groove 31. Compared with the traditional sliding friction, this rolling contact mode greatly reduces the friction force. During the sliding process of the conveying platform 4, the shaking and deviation caused by the friction force can be reduced, making the sliding of the conveying platform 4 more stable. For example, when the conveying platform 4 conveys the pallet 10 at a high speed, the stability of the pallet 10 can be maintained to avoid position deviation and affect the subsequent welding operation. The bottom of the rotating bearing 46 is rotatably embedded with a lower ball 461, and the lower side of the slide groove 31 is in rolling contact through the lower ball 461, further enhancing the stability of the sliding base plate 41 in the slide groove 31, because the lower ball 461 shares a part of the supporting force and provides a smooth rolling path during the sliding process, which enables the conveying platform 4 to still slide smoothly in the slide groove 31 when carrying a heavier pallet 10, reducing the wear of the equipment and extending the service life of the equipment.

[0044] Moreover, the driving component mainly uses the transmission toothed belt 32 to drive the tooth row 42 of the conveyor platform 4. The meshing transmission between the tooth row 42 and the transmission toothed belt 32 has a higher energy transfer efficiency. Compared with some traditional friction transmission methods, the meshing transmission can more effectively transfer the power of the transmission motor 33 to the conveyor platform 4, reducing the energy loss in the transmission process. Therefore, under the same energy input, a faster conveying speed or a greater load capacity can be achieved. In addition, with the use of the rotating bearing 46, the lower ball 461 and the slide groove 31, the conveyor platform 4 can slide on the slide groove 31 more smoothly, thereby improving the production efficiency of the entire workstation, thereby accurately and stably driving the conveyor platform 4 to the welding work site.

[0045] In the above technical scheme, the front and rear sides of the conveying platform 4 are respectively provided with clamping components 44 for fixing the pallet 10, and the front and rear sides of the sliding bottom plate 41 are respectively provided with sliding grooves 413, and the clamping components 44 include a mounting plate 440 that is slidably locked in the sliding grooves 413, so that the mounting plate 440 can slide back and forth in the sliding grooves 413, and finally locked by screws or bolts, so that the clamping components 44 can be adjusted according to the length of the pallet 10. By adjusting the position of the mounting plate 440 in the sliding grooves 413, the wheels 442 can accurately abut the front and rear sides of the pallet 10. No matter how the length of the pallet 10 changes, the clamping components 44 can effectively fix it, thereby improving the versatility of the equipment.

[0046] The swivel plate 441 is rotatably mounted on the upper axis of the mounting plate 440, and a clamping telescopic rod 443 is vertically mounted on one side of the mounting plate 440, wherein one end of the swivel plate 441 is rotatably connected to a wheel 442, and the other end is movably hinged to the telescopic end of the clamping telescopic rod 443. Therefore, the telescopic end of the clamping telescopic rod 443 can be extended upward to push the swivel plate 441 to rotate, and the wheel 442 rotatably connected to the other end of the swivel plate 441 is used to resist the front and rear sides of the tray 10. In this way, when the conveyor platform 4 slides, the contact between the wheel 442 and the tray 10 can limit the shaking of the tray 10 in the front and rear directions, ensuring that the tray 10 remains stable during the conveying process to prevent it from falling off during the conveying process, thereby improving the stability of use. In particular, when the conveyor platform 4 is accelerating or decelerating, the tray 10 will not be easily displaced due to the restriction of the wheel 442, thereby ensuring the safety and reliability of the entire conveying process. In addition, the wheel 442 is circular and is rotatably arranged, so it is not easy to cause wear when contacting the tray 10.

[0047] In this embodiment, the conveying platform 4 includes a sliding base plate 41, and a lifting support plate 43 is arranged on the upper side of the sliding base plate 41 for lifting. Specifically, a lifting telescopic rod 451 and four lifting guide rods 45 are vertically installed in the middle of the sliding base plate 41. The four lifting guide rods 45 slide through the sliding base plate 41 and are connected to the bottom of the lifting support plate 43 to provide guidance for the lifting and lowering of the lifting support plate 43. The telescopic end of the lifting telescopic rod 451 is locked and connected to the lifting support plate 43. When the lifting telescopic rod 451 is extended or retracted, due to the guiding effect of the lifting guide rod 45, the lifting support plate 43 can be accurately lifted and displaced, so that the pallet 10 placed on the lifting support plate 43 can be accurately lifted or lowered to a specified height. For example, in the new energy battery pallet welding intelligent workstation, when the pallet 10 needs to be moved to a high working area, this precise lifting control can ensure that the pallet 10 accurately reaches the target position, facilitates subsequent operations, and is suitable for pallets 10 of different thicknesses; at the same time, in some welding processes, it may be necessary to lift the pallet 10 to a suitable height so that the intelligent welding robot 5 can perform welding operations.

[0048] Two jacking pipes 431 are respectively installed on the left and right sides of the lifting support plate 43. There are four jacking pipes 431 in total, which play an important role in the lifting process of the tray 10. When the lifting support plate 43 rises, the jacking pipes 431 can hold up and stabilize the tray 10.

[0049] The two support rods 411 are respectively installed vertically on the left and right sides of the top surface of the sliding bottom plate 41, and each support rod 411 is adapted to penetrate the inner tube cavity of each lifting pipe 431 from the bottom of the lifting support plate 43 upwards, and an upper ball 412 is installed on the top of the support rod 411, and the upper ball 412 is used for rolling support with the bottom of the tray 10, and a plurality of plug holes 432 are respectively opened on the left and right sides of the lifting support plate 43, and each plug hole 432 is respectively connected with the side of the inner tube cavity of the lifting pipe 431, and a relative auxiliary fixing frame 6 is installed on the left and right sides of the mounting seat 2, and a three-way pipe 63 is relatively slidably arranged on the auxiliary fixing frame 6, and one end of the three-way pipe 63 is connected to a suction pump 631 through a hose, and the other two ends of the three-way pipe 63 are fixedly connected and connected with a conical top plug 64, which corresponds to the side of the lifting support plate 43 or the tray 10, and is used to fix and adsorb the tray 10 through the auxiliary fixing frame 6 and the three-way pipe 63 in cooperation with the suction pump 631;

[0050] When the lifting support plate 43 is in the lowest position, the conical top inserts 64 at both ends of the three-way pipe 63 correspond to the side of the tray 10, and the conical top inserts 64 installed on the three-way pipes 63 of the two auxiliary fixing frames 6 are relatively displaced to push the tray 10 to slide on the upper ball 412. The rolling support mode between the upper ball 412 and the bottom of the tray 10 makes the sliding friction of the tray 10 very small, and it can be easily pushed to correct the position. This correction effect can ensure that the tray 10 is in an accurate state at the initial position, laying a good foundation for subsequent lifting and fixing operations, and avoiding errors in subsequent welding and other operations due to inaccurate initial position;

[0051] When the lifting support plate 43 rises, the upper ball 412 is separated from the bottom of the tray 10, and the four lifting pipes 431 lift the tray 10 up. At this time, the support rod 411 seals the inner tube cavity at the bottom of the lifting pipe 431. This sealing action is conducive to the subsequent negative pressure adsorption operation, and allows the three-way pipes 63 of the two auxiliary fixing frames 6 and the conical top pipes 64 at both ends to adapt to the corresponding sockets 432 on the side of the lifting support plate 43. As the three-way pipe 63 moves relative to each other, the conical top pipes 64 at both ends are respectively inserted into the sockets 432 is connected with the lifting pipe 431, and under the action of the suction pump 631, the lifting pipe 431 generates negative pressure to suck the tray 10 tightly. This negative pressure adsorption fixing method can fix the tray 10 very firmly and prevent the tray 10 from shaking or moving up, down, front, back, left and right in subsequent operations. Moreover, when the conical top insert 64 is inserted into the socket 432 from both sides of the lifting support plate 43, it also has the effect of clamping the lifting support plate 43 firmly, making the entire tray 10 and the lifting support plate 43 structure more stable.

[0052] At the same time, in the above technical scheme, the conical top insert tube 64 is arranged toward one side of the lifting support plate 43 and corresponds to the insertion hole 432. The conical top insert tube 64 can be adapted to be inserted into the inner side of the insertion hole 432, wherein a sealing ring plate 641 is fixedly provided in the middle part of the front end of the conical top insert tube 64, and the sealing ring plate 641 is tightly attached to the insertion hole 432 on the side of the lifting support plate 43, and the diameter of the sealing ring plate 641 is larger than the diameter of the insertion hole 432, which can better block the insertion hole 432, and when the conical top insert tube 64 is relatively displaced, the sealing ring plate 641 can be used to push the lifting support plate 43, so that the force surface is larger, and the clamping effect of the lifting support plate 43 and the sealing effect of the insertion hole 432 are better, and a layer of sealing gasket can be attached to the surface of the sealing ring plate 641 to improve the sealing effect.

[0053] Among them, the upper outer edge of the lifting pipe 431 is chamfered, and the chamfered design can reduce the wear of the lifting pipe 431 when it contacts the pallet 10, avoid damage to the pallet 10 by sharp edges or scratches on the operator during operation, thereby improving the safety of operation; and a layer of rubber gasket is attached to the upper side of the lifting pipe 431 and the surface of the supporting rod 411. The rubber gasket of the lifting pipe 431 can not only increase the friction between the lifting pipe 431 and the pallet 10, making the pallet 10 more stable and less likely to slide during the lifting and fixing process, and prevent scratches during use, but also reduce the noise generated during the lifting and fixing process of the pallet 10, and the rubber gasket of the supporting rod 411 can be more closely connected to the inner cavity of the lifting pipe 431, providing a certain sealing effect, so that the negative pressure adsorption effect of the lifting pipe 431 is better.

[0054] In this embodiment, the auxiliary fixing frame 6 includes two upright frames 61, and a bridge plate 62 is longitudinally locked between the upper sides of the two upright frames 61. Two telescopic top tightening rods 621 and two infrared rangefinders 622 are vertically installed in the middle of the bridge plate 62, and each telescopic top tightening rod 621 and infrared rangefinder 622 are respectively located on both sides of the top of the pallet 10. When the telescopic top tightening rod 621 is extended, pressure can be applied to both sides of the top of the pallet 10. This pressure can limit the shaking of the pallet 10 in the vertical direction, making the pallet 10 more stable during the entire working process, and the telescopic characteristics of the telescopic top tightening rod 621 enable it to adapt to pallets 10 of different heights. For taller pallets 10, the telescopic top tightening rod 621 can be extended to reach a suitable tightening position. For shorter pallets 10, the telescopic top tightening rod 621 can be shortened. Both can effectively perform stabilizing operations on both sides of the top, thereby improving the compatibility of the equipment with pallets 10 of different specifications.

[0055] The infrared rangefinder 622 is located on both sides of the top of the pallet 10. It can monitor the distance between the pallet 10 and itself in real time. By measuring the distance from the top of the pallet 10 to the infrared rangefinder 622, it can be determined whether the vertical position of the pallet 10 is accurate. During the rising or falling process of the pallet 10, if the position of the pallet 10 deviates from the preset value, the infrared rangefinder 622 can detect this deviation in time and feed back the signal to the control system so as to adjust the lifting and lowering of the pallet 10 to ensure that the pallet 10 is in the correct working position, or control the telescopic tightening rod 621 to extend downward by an appropriate distance to avoid excessive extension and squeezing of the pallet 10 to cause deformation, thereby achieving higher control accuracy.

[0056] In order to realize the movable displacement of the above-mentioned three-way tube 63, a connecting plate 65 is locked and connected on one side of the three-way tube 63, and transverse guide rods 651 are respectively fixed on the front and rear sides of the connecting plate 65. The two transverse guide rods 651 are respectively slid through the middle of the two vertical frames 61 to provide guidance for the transverse sliding of the three-way tube 63. Two relative transverse telescopic rods 66 are installed on the mounting seat 2, and the telescopic ends of the two relative transverse telescopic rods 66 are respectively locked and connected with the connecting plates 65 of the two three-way tubes 63. When the transverse telescopic rods 66 are telescoped, the transverse displacement of the three-way tube 63 can be accurately controlled. When the pallet 10 is fixed, the three-way tube 63 can be accurately moved to the designated position corresponding to the lifting support plate 43 or the side of the pallet 10 through the telescopic rods 66, ensuring that subsequent adsorption operations can be carried out smoothly; and since the sizes of different pallets 10 may differ, the design of the three-way tube 63 that can slide transversely can be adjusted according to the width of the pallet 10.

[0057] Furthermore, a connecting frame 67 is fixedly provided on the upper side of the three-way pipe 63, and the connecting frame 67 is laterally slidable and penetrates a plurality of rectangular sliding rods 671, and a top plate 672 is installed on the end of the rectangular sliding rod 671 facing the fixed tray 10, and the rectangular sliding rod 671 is sleeved with a return spring 673, and the top plate 672 is elastically connected to the connecting frame 67 through the return spring 673. When the tray 10 is fixed, the top plate 672 will contact the tray 10 under the action of the return spring 673, and the return spring 673 can provide a certain elastic force so that the top plate 672 applies appropriate pressure to the tray 10 to achieve flexible fixation. This flexible fixing method can effectively fix the tray 10 and prevent it from shaking, and will not cause damage to the tray 10 due to excessive rigid pressure. If the tray 10 has an uneven side surface, the top plate 672 can automatically adjust the contact state with the tray 10 under the elastic action of the return spring 673.

[0058] The present invention also includes a working method of a welding intelligent workstation for a new energy battery tray: placing the tray 10 on the conveying platform 4, at which time the lifting support plate 43 on the sliding bottom plate 41 is in the lowest position, allowing the tray 10 to be placed on the upper ball 412 protruding in the middle of the four lifting pipes 431, and controlling the clamping components 44 on the front and rear sides of the conveying platform 4, allowing the telescopic end of the clamping telescopic rod 443 to extend upward to push the rotating plate 441 to rotate, and using the other end of the rotating plate 441 to rotate and connect the wheel 442 to the front and rear sides of the tray 10. In this way, when the conveying platform 4 slides, the contact between the wheel 442 and the tray 10 can limit the shaking and deviation of the tray 10 in the front and rear directions. At this time, the driving component on the conveying base 3 is controlled to allow the transmission motor 33 to drive The transmission toothed belt 32 is driven, and the transmission toothed belt 32 engages with the tooth row 42 of the transmission conveyor platform 4. The rotating bearing 46 and the lower ball 461 at the bottom of the conveyor platform 4 slide and roll along the slide groove 31 until the transmission is conveyed to the working position of the mounting seat 2, that is, between the two opposite auxiliary fixing frames 6, which are within the welding range of the two intelligent welding manipulators 5. At this time, the two opposite auxiliary fixing frames 6 are provided with two ends of the three-way pipe 63, that is, the conical top plug 64 installed at both ends of the three-way pipe 63, corresponding to the left and right sides of the tray 10. Through a push of the transverse telescopic rod 66, the conical top plug 64 of the two three-way pipes 63 is relatively displaced, and the conical top plug 64 can push the tray 10 to the left and right displacement correction position on the upper ball 412, and the correction is completed. After that, the clamping telescopic rod 443 of the clamping assembly 44 is retracted downward and separated from the front and rear sides of the tray 10, and the lifting support plate 43 rises upward under the action of the lifting telescopic rod 451, and the four lifting pipe fittings 431 gradually become higher than the position of the upper ball 412, and lift the tray 10, while the support plug rod 411 and the upper ball 412 are at a lower position at this time, and their top ends block the inner tube cavity at the bottom of the lifting pipe fitting 431, and only the insertion hole 432 is connected to the upper inner tube cavity of the lifting pipe fitting 431. After the lifting support plate 43 is raised, the insertion hole 432 corresponds to the conical top insertion tube 64 at both ends of the two three-way pipes 63, and the two three-way pipes 63 are relatively displaced laterally for a second time through the secondary push-out of the lateral telescopic rod 66. The conical top insertion tube 64 installed at both ends of the three-way pipe 63 The sealing ring plates 641 of the tapered top inserting tubes 64 are respectively inserted into the respective insertion holes 432 to be connected, and the sealing ring plates 641 of the tapered top inserting tubes 64 are pressed against the outer sides of the insertion holes 432, which not only plays a role in tightening and stabilizing the lifting support plate 43, but also cooperates with the suction pump 631 to make the four lifting tubes 431 generate adsorption force, thereby adsorbing and fixing the tray 10; and when the two three-way tubes 63 are relatively displaced, not only can the tapered top inserting tubes 64 at both ends of the three-way tubes 63 be respectively inserted into the insertion holes 432 to generate a stabilizing effect, but also the top plate 672 can be in contact with both sides of the tray 10 under the action of the return spring 673, and the return spring 673 can provide a certain elastic force, so that the top plate 672 applies appropriate pressure to the tray 10, realizes flexible fixation, and prevents the position from being offset to the left and right.Then, the thickness and position of the pallet 10 are detected by the infrared rangefinder 622, and the left and right sides of the pallet 10 are pressed downward by the telescopic jacking rod 621, and the pallet 10 is pressed against the jacking pipe 431 to further improve the stability of the pallet 10. Finally, the industrial visual inspection camera 71 is used in conjunction with the intelligent welding manipulator 5 to perform welding work. After welding, each structure is reset, the lifting support plate 43 moves downward, and the welded pallet 10 is re-clamped by the moving clamping assembly 44, and is gradually transported outward and naturally cooled under the action of the conveying base 3. ;
