[0002] In the process of manufacturing new energy batteries, it is necessary to laser-weld the adapter plate and the top cover. During the welding process, it is necessary to press the adapter plate and the top cover pole tightly to ensure the welding accuracy.

[0003] In the related art, a welding pressing block is usually used to press the adapter plate and the top cover pole tightly. However, due to the different models of new energy batteries and the different sizes of the welding parts, different welding pressing blocks need to be used for pressing. The welding pressing blocks in the prior art are usually fixed by screws. Every time the welding pressing block needs to be replaced, the screws need to be disassembled and assembled repeatedly, resulting in a complex operation for replacing the welding pressing block and wasting a large amount of processing time.

[0004] The structure of the laser welding pressing block in the related art is relatively complex to disassemble, resulting in low welding efficiency. Content of the Utility Model

[0005] The embodiment of the utility model provides a laser welding pressing block and mechanism, which can solve the problem that the welding pressing block in the prior art is relatively complex to disassemble, resulting in low welding efficiency. The technical solution is as follows:

[0006] In a first aspect, a laser welding pressing block includes: a fixed block, a nozzle and a movable buckle.

[0007] The nozzle is arranged below the fixed block. Two installation bumps are arranged at intervals on the bottom of the fixed block. Horizontal first installation grooves are formed on the opposite side surfaces of each installation bump. An installation part is arranged on the nozzle. The nozzle is attached to the fixed block through the installation part. Two movable buckles are provided and correspond to the two installation bumps one by one. The movable buckle is a trough-shaped structure with an upward opening. An installation protrusion is arranged on the inner side of the movable buckle. The two movable buckles are slidably matched with the first installation grooves of the corresponding installation bumps through the installation protrusions to press the installation part tightly against the bottom of the installation bump.

[0008] Optionally, a second installation groove is arranged on the installation bump. The second installation groove is arranged vertically and communicated with the first installation groove.

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0028] Figure 1 It is the overall structure schematic diagram of the press-fitting mechanism provided by the embodiment of the present utility model; Figure 2 It is the front view schematic diagram of the press-fitting block provided by the embodiment of the present utility model; Figure 3 It is the schematic diagram of one side of the press-fitting block provided by the embodiment of the present utility model; Figure 4 It is the schematic diagram of the nozzle structure provided by the embodiment of the present utility model;

[0029] Figure 5 It is the front view schematic diagram of the fixing block provided by the embodiment of the present utility model; Figure 6 It is the schematic diagram of one side of the fixing block provided by the embodiment of the present utility model; Figure 7 It is the bottom view schematic diagram of the fixing block provided by the embodiment of the present utility model; Figure 8This is a schematic diagram of the movable buckle structure provided by the embodiment of the utility model. As Figures 1 to 8 shown, a laser welding and pressing block includes: a fixed block 1, a nozzle 2, and a movable buckle 3. The nozzle 2 is arranged below the fixed block 1. Two mounting bumps 11 are spaced apart on the bottom of the fixed block 1. Horizontal first mounting grooves 12 are formed on opposite sides of each mounting bump 11. An installation portion 21 is provided on the nozzle 2. The nozzle 2 is attached to the fixed block 1 through the installation portion 21. Two movable buckles 3 are provided and correspond to the two mounting bumps 11 one by one. The movable buckle 3 is a trough-shaped structure with an upward opening. An installation protrusion 31 is arranged on the inner side of the movable buckle 3. The two movable buckles 3 are slidably engaged with the first mounting grooves 12 of the corresponding mounting bumps 11 through the installation protrusions 31 to press the installation portion 21 against the bottom of the mounting bump 11.

[0030] Exemplarily, in the embodiment of the utility model, as Figure 4 shown, the nozzle 2 is a bucket-shaped structure. In order to cooperate with the mounting bump 11 at the bottom of the fixed block 1, the installation portion 21 is a trough-shaped structure, so that the mounting bump 11 is embedded in the trough-shaped structure, promoting the close fit between the nozzle 2 and the fixed block 1. Horizontal first mounting grooves 12 are formed on opposite sides of each mounting bump 11. The first mounting grooves 12 are horizontally arranged starting from the edge of the mounting bump 11. The first mounting grooves 12 are not through grooves to prevent the movable buckle 3 from sliding out from one end of the first mounting groove 12 after entering from one end during the installation process. After closely attaching the nozzle 2 to the fixed block 1 from below the fixed block 1, slide the installation protrusion 31 on the movable buckle 3 into the first mounting groove 12, so that the trough bottom of the movable buckle 3 supports the nozzle 2, thereby fixing the nozzle 2 and the fixed block 1 together. When it is necessary to replace a different nozzle 2, slide the movable buckle 3 out of the mounting bump 11 along the direction of the first mounting groove 12, so that the movable buckle 3 is separated from the mounting bump 11, thereby releasing the locked installation of the fixed block 1 and the nozzle 2. After removing the nozzle 2, cooperate the different model nozzle 2 to be reinstalled with the fixed block 1, and then fix the fixed block 1 and the nozzle 2 together through the movable buckle 3. Fixing the fixed block 1 and the nozzle 2 through this structure is convenient for operation. Only by sliding the movable buckle 3 can the nozzle 2 be fixed to or separated from the fixed block 1, thereby reducing the operation time for replacing the nozzle 2 and improving the processing efficiency of welding.

[0031] A laser welding and pressing block and mechanism provided by an embodiment of the present utility model. A first installation groove 12 is provided on a fixed block 1. By matching an installation protrusion 31 with the first installation groove 12 along the direction of the first installation groove 12 through a movable buckle 3, the fixed block 1 and a nozzle 2 can be quickly fixed together. When it is necessary to replace nozzles 2 of different models, only need to slide the movable buckle 3 along the first installation groove 12 so that the installation protrusion 31 is disengaged from the first installation groove 12, then the fixed block 1 and the nozzle 2 can be separated. Compared with the prior art where screws need to be repeatedly disassembled, the laser welding and pressing block and mechanism provided by the embodiment of the present utility model are convenient to operate and can effectively solve the problem that the disassembly of the welding and pressing block in the prior art is relatively complicated, resulting in low welding efficiency.

[0032] Optionally, a second installation groove 13 is provided on the installation protrusion 11. The second installation groove 13 is vertically arranged and communicates with the first installation groove 12.

[0033] Exemplarily, in the embodiment of the present utility model, a second installation groove 13 is also provided on the installation protrusion 11. After the nozzle 2 and the fixed block 1 are fixed by the movable buckle 3, there is still a certain gap between the nozzle 2 and the fixed block 1. Due to gravity, the nozzle 2 may sink. By providing the second installation groove 13, the installation protrusion 31 sinks into the lower half of the second installation groove 13, so that the second installation groove 13 plays a limiting role in the horizontal direction on the installation protrusion 31, preventing the movable buckle 3 from shaking in the horizontal direction. When the nozzle 2 processes the battery, the nozzle 2 presses tightly on the surface of the battery. At this time, due to the reaction force of the pressure, the nozzle 2 rises relative to the fixed block 1, so that the installation protrusion 31 moves to the upper half of the second installation groove 13, so that the second installation groove 13 plays a limiting role in the horizontal direction on the installation protrusion 31. Thus, during the installation process and the working process of the laser welding and pressing block in this embodiment, the second installation groove 13 will limit the movable buckle 3 in the horizontal direction, so that the movable buckle 3 can connect the nozzle 2 and the fixed block 1 more stably, thereby improving the stability of this laser welding and pressing block.

[0034] Optionally, a spring 4 is provided between the fixed block 1 and the nozzle 2.

[0035] Exemplarily, in the embodiment of the present utility model, a spring installation hole 41 is provided at the bottom of the fixed block 1. Since there is a certain gap between the fixed block 1 and the nozzle 2 during installation, and due to the setting of the second installation groove 13, the nozzle 2 will move up and down relative to the fixed block 1. By providing a spring 4 between the spring installation hole 41 of the fixed block 1 and the nozzle 2, when the nozzle 2 moves up and down relative to the fixed block 1, the hard contact between the nozzle 2 and the fixed block 1 is slowed down, thereby protecting the nozzle 2 and the fixed block 1 and improving the service life of this laser welding and pressing block.

[0036] Optionally, a first laser welding hole 22 arranged in the vertical direction and a first air hole 23 communicating with the first laser welding hole 22 are formed at the top of the nozzle 2. A second laser welding hole 14 matching the first laser welding hole 22 is formed on the fixing block 1. A second air hole 15 is formed on one side of the fixing block 1, and the second air hole 15 communicates with the first air hole 23.

[0037] Exemplarily, in the embodiment of the present invention, the second air hole 15 is communicated with an external nitrogen storage tank. When laser welding is performed on the battery located below the nozzle 2 through the first laser welding hole 22 and the second laser welding hole 14, by introducing nitrogen into the second air hole 15, the nitrogen moves to the first laser welding hole 22 through the first air hole 23 via the second air hole 15, providing a shielding gas for the laser welding process. By introducing nitrogen, the surface of the laser welding will not turn black and the welding performance is ensured, thereby improving the practicability of the laser welding and pressing block.

[0038] Optionally, a dust extraction port 16 is formed on one side of the fixing block 1, and the dust extraction port 16 communicates with the first laser welding hole 22.

[0039] Exemplarily, in the embodiment of the present invention, the dust extraction port 16 is connected to an external dust extractor. After the welding process is completed, the laser is stopped, and after stopping the introduction of nitrogen into the first laser welding hole 22, since laser welding will generate welding slag, by providing the dust extraction port 16, the welding slag after welding can be removed, thereby ensuring the cleanliness of the surface of the workpiece, and further improving the practicability of the laser welding and pressing block.

[0040] A laser welding and pressing mechanism includes the aforementioned laser welding and pressing block, and further includes a lifting table 5, two fixed mounting plates 6, a sliding rod 7 and a sliding block 8. The two fixed mounting plates 6 are arranged in parallel at intervals. The sliding rod 7 is mounted between the two fixed mounting plates 6. The sliding block 8 is slidably arranged on the sliding rod 7. The sliding block 8 is arranged on the top of the fixing block 1. The lifting table 5 is arranged below the fixing block 1 and the nozzle 2 in a liftable manner.

[0041] Exemplarily, in the embodiment of the present invention, the battery to be processed is placed on the lifting table 5. When welding processing is required, by controlling the lifting of the lifting table 5, the battery is moved to a suitable height. At the same time, by sliding the sliding block 8 on the sliding rod 7, the fixing block 1 and the nozzle 2 are driven to move to the position where welding is required. The fixed mounting plate 6 provides a supporting force for the sliding rod 7 and the laser welding and pressing block. With this structure, during the welding process, the welding position to be processed can be quickly located, improving the operation convenience of the laser welding and pressing mechanism.

[0042] Optionally, two sliding blocks 8 and two laser welding and pressing blocks are arranged on the sliding rod 7.

[0043] Exemplarily, in the embodiment of the present utility model, when welding and processing the adapter plate and the pole column of the battery top cover, generally there are two pole columns on the battery top cover. By arranging two sets of laser welding and pressing blocks in the present utility model on the sliding rod 7, the two pole columns on one battery top cover can be simultaneously pressed and welded at the same time to ensure the welding precision between the two pole columns and improve the welding efficiency at the same time.

[0044] Optionally, a support rib plate 9 is provided at one end of the fixed mounting plate 6 away from the sliding rod 7.

[0045] Exemplarily, in the embodiment of the present utility model, by providing a support rib plate 9 at one end of the fixed mounting plate 6 away from the sliding rod 7, the load-bearing capacity of the fixed mounting plate 6 is enhanced, thereby improving the stability of the present laser welding and pressing mechanism.
