[0001] This application relates to the technical field of welding devices, and more specifically, to a welding tooling for a new energy battery housing. Background Art

[0002] With the global emphasis on environmental protection and sustainable development, the new energy vehicle industry has shown a rapid development trend. As the core component of new energy vehicles, the performance, safety, and production efficiency of new energy batteries have attracted much attention. New energy batteries usually consist of multiple battery cells, which need to be encapsulated in a housing to provide protection and electrical connection. The welding quality of the battery housing directly affects the sealing, safety, and overall performance of the battery, so higher requirements are put forward for the welding tooling. After retrieval, the existing publication number: CN109822239A, discloses a synchronous welding assembly for a new energy battery housing; including a battery housing, a clamping fitting is sleeved outside the battery housing, and an elastic fitting is clamped between them. The elastic fitting and the battery housing are in interference fit with each other. The clamping fitting squeezes the elastic fitting outside the battery housing through pressure, and the elastic fitting compresses and generates extrusion force on the battery housing; the clamping fitting includes a lower support plate, and the lower support plate is provided with a positioning portion corresponding to the elastic fitting. The elastic fitting is sleeved outside the battery housing, and the two are respectively limited and installed in the positioning portion; the lower support plate is provided with an installation groove, and the battery housing penetrates and is inserted into the installation groove. By using an elastic fitting and a clamping fitting outside the battery housing, the elastic fitting is subjected to the squeezing force and the downward pressure, and the battery housing is synchronously welded under the action of these two forces. The inventor found the following problems in the process of implementing this application: During the welding process of the existing new energy battery welding equipment, it is necessary to use a clamping member to clamp the battery housing to be welded and then weld the battery housing. Therefore, the size of the battery housing to be welded is often directly affected by the area of the battery housing, resulting in the inability to clamp the welding ends of some large-size or special-structured battery types. Moreover, when welding the battery housing, it is mostly the operator who places and takes it, and this operation method will affect the production rate. Therefore, a welding tooling for a new energy battery housing is proposed to solve the above problems. Summary of the Invention

The sliding plate is slidably connected to the top ends of the two groups of slide rails, and side stop frames are arranged on both sides of the sliding plate.

[0007] Preferably, the welding table further includes a welding housing, a second electric support stop bar, an electric push rod, and a conveyor belt. The welding housing is placed between the two side stop frames of the sliding plate. The second electric support stop bar is arranged on the side of the welding housing. An electric push rod is arranged between the welding housing and the shielding plate. A conveyor belt is arranged on the side of the welding housing away from the electric push rod. When the electric push rod is driven and controls the output end to move forward, the welding housing is pushed to move horizontally and move onto the conveyor belt.

[0008] Preferably, the first side shielding electric support stop bar includes a fixing plate, connecting frames, and a fixed plug-in frame.

[0013] Preferably, a dust suction channel is arranged on the side of the installation base, and rollers are arranged at the bottom end of the installation base. The rollers have an electric braking structure.

[0014] Technical effects and advantages of this application: 1. Compared with the prior art, this new energy battery shell welding tooling integrates the core processes of cover placing, positioning, welding, and unloading into the equipment through mechanical automation design, enabling the grasping, fitting and positioning, welding, and unloading of the cover. It is automatically completed by the cover placing guide rail assembly, welding assembly, and pushing structure, avoiding quality fluctuations caused by unstable manual operation. The cover placing guide rail assembly is used for fitting and fixing, and the cover placing guide rail assembly applies pressure to the welding contact surface between the cover and the shell, making the cover stably fit on the welding end of the shell, rather than rigidly clamping the entire workpiece. This contact surface positioning mode can avoid the stress influence on the whole workpiece when using the traditional clamping structure, ensuring the relative position stability between the cover and the shell during the welding process, and reducing the deformation problem caused by uneven clamping force from the root.

[0015] 2. Compared with the prior art, this new energy battery shell welding tooling realizes the full-process automation of the welding shell from positioning, welding to blanking through the linkage of the electric push rod, support stop rod, and buckle mechanism, reducing manual operation errors and improving production efficiency. The design of two welding stations can further support assembly line operation and shorten the cycle time. The use of double electric support stop rods and side support frames forms a multi-point support structure, which can effectively restrain the influence of welding thermal deformation on the shell during the welding process. At the same time, the sliding plate and the slide rail are matched with each other to ensure the linear motion accuracy of the welding shell when adjusting the position, reducing welding defects caused by positioning deviation, and the snap-type reset mechanism ensures the consistency of the sliding plate returning to the initial position each time, providing a stable reference for the positioning of subsequent workpieces.

[0016] 3. Compared with the prior art, for this new energy battery housing welding tooling, the electric push rod directly drives the sliding plate to carry the welding housing for movement, and the pushing path is docked with the conveyor belt, reducing the repetitive time for the operator to normally handle and complete the welding. Moreover, the snap - type reset design uses the push rod to reset, synchronously driving the sliding plate to return, shortening the idle stroke time, thus shortening the cycle period of a single workpiece. In addition, the layout of the two welding stations can support parallel operations of loading, welding, and unloading, which can optimize the utilization rate of the equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0020] Embodiment 1 As shown in the attached Figures 1 to 8 A welding tooling for the housing of a new energy battery, including a box body 1 and a welding table 7. A motor box 2 is fixedly connected to the top end of the box body 1, and a welding cavity 5 is arranged inside the box body 1. A safety door 3 is arranged at the edge of the box body 1, and an installation base 4 is fixedly connected to the bottom end of the box body 1. Two sides of the inner wall of the welding cavity 5 of the box body 1 are fixedly connected with a cover placing guide rail assembly 8, and a welding assembly 6 is arranged directly below the box body 1 at the motor box 2. A welding table 7 is placed below the welding assembly 6.

[0021] Among them, during the process of welding the new energy battery, since its battery housing adopts a metal structure, a shell can be quickly formed through welding to place the battery core. However, during the welding process, the operator first connects and fixes the battery housing and the sheet to be welded before welding. At this time, a clamping structure is used to fix the battery housing and perform welding. However, in this application, the welding and cover placing are integrated operations, and semi-automatic operation can be realized. The operator only needs to place the battery housing to be welded at the welding table 7 in the welding cavity 5 inside the box body 1. At this time, the cover placing guide rail assembly 8 drives the cover to be welded to move to the welding end of the battery housing. At this time, the cover placing guide rail assembly 8 fixes the contact of the cover fitting on the battery housing. At this time, the welding assembly 6 performs welding. After the basic welding is completed, the cover placing guide rail assembly 8 releases and continues to clamp the cover. At this time, after the welding assembly 6 completes welding, the clamping structure on the welding table 7 releases, and the welded battery housing is pushed by a pushing structure to the outer conveying end and conveyed.

[0022] Embodiment 2 On the basis of Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working methods, as Figures 1 to 8 shown. For details, see the following description: As a preferred embodiment, the welding table 7 includes a support base 9, a plug-in positioning groove frame 10, a shielding plate 11, a support bracket 12, and a mounting plate 13. The bottom end of the support base 9 is bolted with the plug-in positioning groove frame 10. When placing the support base 9, the support base 9 is connected through the plug-in positioning groove frame 10 bolted thereto. Therefore, when installing the support base 9 at the top of the mounting base 4, the plug-in positioning groove frame 10 is inserted into the support base 9 to complete the fixation of the support base 9 and the welding table 7. The top end of the support base 9 is fixedly connected with the shielding plate 11. Then, the shielding plate 11 installed at the top of the support base 9 is in the positive contact surface of the safety door 3. Therefore, when the operator places the battery housing, the operator needs to pay attention to the position of the shielding plate 11. When the operator's attention is not concentrated, the battery housing will hit the shielding plate 11, thus attracting the operator's attention. Moreover, it can also prevent the operator's body from extending into the welding cavity 5 of the box body 1. Even if the operator reaches into the welding cavity 5 of the box body 1, the operator can be supported by the shielding plate 11 to protect the operator. Both sides of the shielding plate 11 are installed with support brackets 12, and the mounting plate 13 is placed on the side of the support bracket 12. A photoelectric sensor is installed on the side of the mounting plate 13 to monitor the difference in distance during the process of placing and moving the battery housing for convenient adjustment.

[0023] As a preferred embodiment, the welding table 7 further includes a first side protection electric support bar 14, a placement plate 15, slide rails 16, a sliding plate 17, and a side blocking frame 18. The first side protection electric support bar 14 includes a fixed plate 1401, a connecting frame 1402, and a fixed plug-in frame 1403. The top of the fixed plate 1401 is fixedly connected to two groups of connecting frames 1402. The fixed plate 1401 is connected to the support base 9 and can be detachably operated by bolts. This not only facilitates fixation but also allows for position adjustment. Above the fixed plate 1401, two groups of connecting frames 1402 are installed to complete the fixation of the connecting frames 1402. A fixed plug-in frame 1403 is installed between the two groups of connecting frames 1402 by bolts. Then, the fixed plug-in frame 1403 is connected inside the two groups of connecting frames 1402, thus installing the fixed plug-in frame 1402 inside the connecting frame 1403 to complete the fixation. The first side protection electric support bar 14 further includes an electric rod 1404 and a limiting frame 1405. The outer diameter surface of the electric rod 1404 is sleeved with the limiting frame 1405. Then, the electric rod 1404 is inserted into the inside of the fixed plug-in frame 1403, and the electric rod 1404 is connected to the limiting frame 1405, thus completing the fixation of the electric rod 1404 and using the limiting frame 1405 to connect the electric rod 1404, thereby supporting the electric rod 1404 during the driving process. The electric rod 1404 and the fixed plug-in frame 1403 are fixed by a detachable buckle structure. Below the pushing end of the first side protection electric support bar 14, there is a placement plate 15. The top of the placement plate 15 is fixedly connected to two groups of slide rails 16. The two groups of slide rails 16 are arranged on the placement plate 15. At this time, the electric push rod 21 can push the sliding plate 17 to move, thus completing the movement of the sliding plate 17, so that the welding shell 19 on the placement plate 15 can be pushed, thereby driving the welding shell 19 to move. The top of the two groups of slide rails 16 is slidably connected to the sliding plate 17. Both sides of the sliding plate 17 are provided with side blocking frames 18. One end of the side blocking frames 18 on both sides of the battery shell is installed on the placement plate 15 by bolts, and the other end of the side blocking frame 18 is installed on the pushing end of the first side protection electric support bar 14. Thus, when the first side protection electric support bar 14 moves, the side blocking frame 18 on the pushing end of the first side protection electric support bar 14 moves and contacts the battery shell, causing the battery shell to be pressed and fixed to the side blocking frame 18 at the other end, thereby completing the fixation of the battery shell.

[0024] As a preferred embodiment, the welding table 7 further includes a welding housing 19, a second electric support stop bar 20, an electric push rod 21 and a conveyor belt 22. A welding housing 19 is placed between two sets of side stop frames 18 where the sliding plate 17 is located. At this time, the structure of the second electric support stop bar 20 is the same as that of the first side protection electric support stop bar 14. There are two sets of positions for the welding housing 19, and the positions of the first side protection electric support stop bar 14 and the second electric support stop bar 20 are symmetrically arranged on the side away from the welding housing 19, so as to complete the fixation of the two welding housings 19. The side of the welding housing 19 is provided with a second electric support stop bar 20, and an electric push rod 21 is arranged between the welding housing 19 and the protection plate 11. Then the welding housing 19 is the main body for welding. At this time, after the fixation is completed by the cooperation of the electric push rod 21 and the side stop frame 18, the electric push rod 21 is connected to the sliding plate 17 below the welding housing 19. After the position of the welding housing 19 is adjusted, the welding housing 19 is connected by the cooperation of the first side protection electric support stop bar 14, so as to complete the adjustment of the position of the welding housing 19. A conveyor belt 22 is arranged on the side of the welding housing 19 away from the electric push rod 21. And after the welding is completed, when the positions of the sliding plate 17 connected by the electric push rod 21 at the first side protection electric support stop bar 14 and the second electric support stop bar 20 are released, the electric push rod 21 drives the welding housing 19 on the sliding plate 17 to move, so that the welding housing 19 on the sliding plate 17 moves onto the conveyor belt 22. At this time, when the electric push rod 21 is driven and the output end moves forward, it pushes the welding housing 19 to move horizontally and move onto the conveyor belt 22. A buckle is arranged between the electric push rod 21 and the sliding plate 17. When the welding housing 19 is pushed, the set buckle drives the sliding plate 17 to reset along the slide rail 16 after the electric push rod 21 is reset, so that the electric push rod 21 pushes the welding housing 19 to move, and then the sliding plate 17 can be driven to reset during the reset.

[0025] As a preferred embodiment, plug-in slots 901 are provided at the four sides of the support base 9, and a support plate 902 is installed between the support base 9 and the protection plate 11, and a detachable structure is formed between the support base 9 and the support plate 902 by bolts.

[0026] As a preferred embodiment, the lid placing guide rail assembly 8 includes a first sliding guide rail 23, a docking frame 24, a second sliding guide rail 25 and a lifting suction bracket 26. Docking frames 24 are installed at the edges of the two groups of first sliding guide rails 23 by bolts. The first sliding guide rails 23 are installed on the inner wall of the welding cavity 5 of the box body 1 through the docking frames 24. A second sliding guide rail 25 is fixedly connected between the two groups of first sliding guide rails 23. The second sliding guide rail 25 is connected to the output end of the first sliding guide rail 23. When the second sliding guide rail 25 moves, the two groups of first sliding guide rails 23 drive the second sliding guide rail 25 to move. A lifting suction bracket 26 is installed at the moving end of the second sliding guide rail 25. A lifting frame and a vacuum suction head are arranged inside the lifting suction bracket 26. When taking the shell of the welding shell 19, the electric rod 1404 in the lifting frame drives the vacuum suction head to move, and drives the lid to move above the welding shell 19, so as to complete the connection of the welding shell 19.

[0027] As a preferred embodiment, the welding assembly 6 includes a sliding groove 601, an information interface 602, a connecting bracket 603 and a welding head 604. The information interface 602 is placed below the sliding groove 601. The motor box 2 and the welding assembly 6 are connected through the sliding groove 601, and the welding assembly 6 can be slidably connected to the motor box 2 along the sliding groove 601, so that the motor box 2 can move in the welding cavity 5. A connecting bracket 603 is arranged below the information interface 602, and a welding head 604 is fixedly connected to the bottom end of the connecting bracket 603.

[0028] As a preferred embodiment, a dust suction channel 401 is arranged on the side of the installation base 4, and rollers 402 are arranged at the bottom end of the installation base 4, and the rollers 402 have an electric braking structure.

[0029] The working process of this application is as follows: Firstly, when placing the support base 9, the support base 9 is connected through the plug-in positioning groove frame 10 installed by bolts. Therefore, when installing the support base 9 at the top of the installation base 4, the plug-in positioning groove frame 10 is inserted into the support base 9 at this time, thus completing the fixation of the support base 9 and the welding table 7. Then, the shielding plate 11 installed at the top of the support base 9 is in the positive contact surface of the safety door 3. Therefore, when the operator places the battery housing, the operator needs to pay attention to the position of the shielding plate 11 at this time. When the operator's attention is not concentrated, the battery housing will hit the shielding plate 11, thus attracting the operator's attention, and it can also prevent the operator's body from extending into the welding cavity 5 of the box body 1. And even if the operator extends into the welding cavity 5 of the box body 1, at this time, the operator can be supported by the shielding plate 11, thus protecting the operator. A photoelectric sensor is installed on the side of the mounting plate 13 to monitor the difference in distance during the process of placing and moving the battery housing, so as to facilitate adjustment.

[0030] The first side protection electric support bar 14 includes a fixing plate 1401, a connecting frame 1402, and a fixed plug-in frame 1403. Two groups of connecting frames 1402 are fixedly connected to the top of the fixing plate 1401. The fixing plate 1401 is connected to the support base 9 and can be detachably operated by bolts. While facilitating fixation, the position can also be adjusted. Then, two groups of connecting frames 1402 are installed above the fixing plate 1401 to complete the fixation of the connecting frames 1402. A fixed plug-in frame 1403 is installed between the two groups of connecting frames 1402 through bolts. Then, the fixed plug-in frame 1403 is connected inside the two groups of connecting frames 1402, thus installing the fixed plug-in frame 1402 in the connecting frame 1403 to complete the fixation. The first side protection electric support bar 14 also includes an electric rod 1404 and a limiting frame 1405. The outer diameter surface of the electric rod 1404 is sleeved with the limiting frame 1405. Then, the electric rod 1404 is inserted into the inside of the fixed plug-in frame 1403, and then the electric rod 1404 is connected to the limiting frame 1405, thus completing the fixation of the electric rod 1404 and using the limiting frame 1405 to connect the electric rod 1404, thus completing the support for the electric rod 1404 during the driving process. And the electric rod 1404 and the fixed plug-in frame 1403 are fixed by a detachable buckle structure. One end of the side blocking frame 18 on both sides of the battery housing is installed on the placing plate 15 through bolts, and the other end of the side blocking frame 18 is installed on the pushing end of the first side protection electric support bar 14. Thus, when the first side protection electric support bar 14 moves, the side blocking frame 18 on the pushing end of the first side protection electric support bar 14 moves and contacts the battery housing, causing the battery housing to be pressed and fixed to the side blocking frame 18 at the other end, thus completing the fixation of the battery housing.

[0031] At this time, the structure of the second electric support rod 20 is the same as that of the first side guard electric support rod 14. There are two groups of positions for welding the outer shell 19. Then the welding outer shell 19 is the main body for welding. After the fixing is completed by the electric push rod 21 cooperating with the side guard frame 18, the electric push rod 21 is connected to the sliding plate 17 below the welding outer shell 19. After the position of the welding outer shell 19 is adjusted, it is connected to the welding outer shell 19 in cooperation with the first side guard electric support rod 14, so as to complete the adjustment of the position of the welding outer shell 19. And after the welding is completed, when the positions of the first side guard electric support rod 14 and the second electric support rod 20 where the sliding plate 17 connected to the electric push rod 21 are released, the electric push rod 21 drives the welding outer shell 19 on the sliding plate 17 to move, so that the welding outer shell 19 on the sliding plate 17 moves onto the conveyor belt 22. At this time, the welding outer shell 19, when driven by the electric push rod 21 and the output end is controlled to move forward, pushes the welding outer shell 19 to move horizontally and move onto the conveyor belt 22. A buckle is provided between the electric push rod 21 and the sliding plate 17. When the welding outer shell 19 is pushed, the set buckle drives the sliding plate 17 to reset along the slide rail 16 after the electric push rod 21 is reset, so that the electric push rod 21 pushes the welding outer shell 19 to move, and then can drive the sliding plate 17 to reset during the reset.

[0032] The first sliding guide rail 23 provided is installed on the inner wall of the welding cavity 5 of the box body 1 through the docking frame 24, and the second sliding guide rail 25 connected to the output end of the first sliding guide rail 23. When the second sliding guide rail 25 moves, the two groups of first sliding guide rails 23 drive the second sliding guide rail 25 to move. The lifting and adsorption bracket 26 is internally provided with a lifting frame and a vacuum adsorption head. When the shell of the welding outer shell 19 is taken, the electric rod 1404 in the lifting frame drives the vacuum adsorption head to move and drives the cover body to move above the welding outer shell 19, so as to complete the connection to the welding outer shell 19. The above is the working principle of this new energy battery shell welding tooling.
