Description

Technical Field

[0001] This invention relates to the field of laser welding technology, and in particular to a laser welding device for energy storage products. Background Technology

[0002] Laser welding is a widely used welding process in the processing of energy storage products. For example, Chinese patent CN117139843A discloses a polymer laser welding device for bipolar plates of energy storage batteries, including a base, a table, a Y-axis moving assembly, a slide block, an X-axis module, a Z-axis module, a laser welding section, and tooling. The base and table serve as carriers for mounting the equipment components. The slide block is slidably mounted on the base or table, providing guidance for the Y-axis moving assembly. Through the upper mold moving assembly within the tooling, the bipolar plates can be easily placed during welding by moving the upper mold. Furthermore, during welding, the bipolar plates only need to move vertically, not horizontally, preventing positional shifts and improving the yield and precision of the welding process.

[0003] For large-sized products, a single welding robot can usually only weld products on a single support frame. If a single welding robot welds products on multiple support frames, the strong light and fumes generated during welding will affect the loading and unloading of materials on adjacent support frames, resulting in low product welding efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a laser welding device for energy storage products, so as to solve the problem of low welding efficiency when laser welding energy storage products is performed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laser welding device for energy storage products, comprising:

[0006] A welding robot equipped with a laser welding head;

[0007] A tilting frame is used to fix the product to be welded. Several tilting frames are arranged around the circumference of the welding robot.

[0008] A baffle is installed between two adjacent flipping frames;

[0009] The moving component includes a slide rail, a welding robot is mounted on the extension of the slide rail, a slider is mounted on the slide rail, and a baffle is fixedly mounted on the slider.

[0010] The controller is used to obtain the welding point coordinates of the laser welding head. Based on the welding point coordinates, the controller controls the slider to move the shielding plate, so that the center line L1 of the shielding plate and the laser welding head are on a concentric circle with the welding robot base as the center.

[0011] As a further description of the above technical solution:

[0012] The flipping frame includes a base and a support frame. The support frame is rotatably mounted on the base, and the product to be welded is mounted on the support frame.

[0013] As a further description of the above technical solution:

[0014] The welding robot is installed in an isolation room, and the top of the isolation room is equipped with an exhaust pipe, which is connected to a negative pressure generating device.

[0015] As a further description of the above technical solution:

[0016] A smoke sensor is installed on the surface of the shield.

[0017] As a further description of the above technical solution:

[0018] The bottom of the baffle plate is equipped with support feet, which are detachably mounted on the connecting seat, and the connecting seat is fixedly mounted on the slider.

[0019] As a further description of the above technical solution:

[0020] The connector is provided with at least one pin, and the support leg is provided with a clearance hole corresponding to the position of the pin.

[0021] As a further description of the above technical solution:

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In this invention, during the welding process, the shielding plate is flexibly adjusted in position by the controller. After the controller obtains the welding point coordinates of the laser welding head, it calculates the distance that needs to be compensated for between the center line L1 of the shielding plate and the welding robot base based on the welding point coordinates. This ensures that after the shielding plate moves along the slide rail and approaches or moves away from the welding robot, the center line L1 of the shielding plate and the laser welding head are on a concentric circle with the welding robot base as the center, thereby effectively improving the shielding effect of the shielding plate.

[0025] 2. In this invention, the welding robot is housed in an isolation room. An exhaust pipe is located on the top of the isolation room and connected to a negative pressure generator.

[0039] Example 1

[0040] Please see Figure 1-5 The present invention provides a technical solution: a laser welding device for energy storage products, comprising:

[0041] Welding robot 1, which is equipped with laser welding head 11;

[0042] A rotating frame 2 is used to fix the product to be welded, and several rotating frames 2 are arranged around the welding robot 1.

[0043] A baffle plate 3 is installed between two adjacent flipping frames 2;

[0044] The moving component includes a slide rail 4, a welding robot 1 is set on the extension line of the slide rail 4, a slider 41 is provided on the slide rail 4, and a baffle plate 3 is fixedly installed on the slider 41.

[0045] The controller is used to obtain the welding point coordinates of the laser welding head 11. The controller controls the slider 41 to move the shielding plate 3 according to the welding point coordinates, so that the center line L1 of the shielding plate 3 and the laser welding head 11 are on a concentric circle with the base of the welding robot 1 as the center.

[0046] The flipping frame 2 includes a base 21 and a support frame 22. The support frame 22 is rotatably mounted on the base 21, and the product to be welded is mounted on the support frame 22. The rotating shaft of the support frame 22 is connected to the output end of a rotary motor on the base 21, which enables the adjustment of the rotation angle of the support frame 22, facilitating the adjustment of the welding angle of the product to be welded.

[0047] Welding robot 1 is installed inside isolation room 5. The top of isolation room 5 is equipped with an exhaust port 51, which is connected to a negative pressure generating device. Isolation room 5 is equipped with an openable door. During welding, the isolation room is closed, and the negative pressure generating device is connected through the exhaust port 51 at the top to draw in the welding fumes, which are then adsorbed and filtered.

[0048] A fume sensor is installed on the surface of the baffle plate 3. The fume sensor detects the amount of fume generated during the welding process of the welding robot 1 and feeds it back to the controller. Since the baffle plate 3 moves with the welding point, it can accurately reflect the amount of fume generated. When the amount of fume changes, the controller can control the negative pressure generating device to increase the power of the fume extraction to prevent the fume from affecting other workstations.

[0049] The bottom of the baffle plate 3 is provided with a support leg 31, which is detachably mounted on the connecting seat 32. The connecting seat 32 is fixedly mounted on the slider 41. The connecting seat 32 is provided with at least one pin 321, and the support leg 31 is provided with a clearance hole corresponding to the pin 321. The support leg 31 and the connecting seat 32 are fixed by the pin 321, realizing detachable installation.

[0050] The bottom of the connector 32 is provided with a stepped surface, and an electromagnet 33 is installed in the stepped surface. The pin 321 passes through the connector 32 and contacts the electromagnet 33. When the baffle 3 is removed, the electromagnet 33 is energized to attract the pin 321, preventing the pin 321 from falling off. Under normal conditions, the pin 321 is not attracted, which facilitates the installation and removal of the baffle 3.

[0051] Three rotating frames are arranged around the welding robot to effectively improve welding efficiency.

[0052] Working principle: The welding robot 1 can weld products on the circumferentially arranged flipping frames 2. Adjacent flipping frames 2 are separated by a baffle plate 3 to prevent the welding of products on one flipping frame 2 from affecting the loading and unloading of products on adjacent flipping frames 2. During the welding process, the baffle plate 3 is flexibly adjusted by the controller. After the controller obtains the welding point coordinates of the laser welding head 11, it calculates the distance that needs to be compensated for between the center line L1 of the baffle plate 3 and the base of the welding robot 1 based on the welding point coordinates. This ensures that after the baffle plate 3 moves along the slide rail 4, approaching or moving away from the welding robot 1, the center line L1 of the baffle plate 3 and the laser welding head 11 are on a concentric circle with the base of the welding robot 1 as the center, thereby effectively improving the shielding effect of the baffle plate 3.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
