Description

Technical Field

[0001] This utility model relates to the field of water-guided laser cutting technology for steel-shell battery flanges, and in particular to a water-guided laser cutting fixture. Background Technology

[0002] With societal development, the pace of technological advancement in 3C consumer electronics is accelerating, and consumers are placing increasingly higher demands on the performance and aesthetics of these products. As the power source of electronic products, batteries, particularly aesthetically pleasing and high-performance steel-cased cells, have emerged as a necessity. In the current application of steel-cased square battery cell processing technology, after the battery cover is welded to the battery casing, the battery flange needs to be cut. Cutting the battery flange effectively removes excess material from the battery cover, making it a necessary processing step.

[0003] Water-guided laser processing is an advanced machining technology that uses a micro-water jet to guide a laser beam. This technology couples a high-energy laser beam into a high-speed water jet. Due to the difference in refractive index between water and air, the laser beam propagating in the water undergoes total internal reflection at the water-air interface, confining it within the water jet. The water jet then guides the laser beam to the workpiece surface for machining. Because the water jet diameter is extremely small, water-guided laser processing achieves micro-damage cutting. Furthermore, the water jet washes away the molten material and chips generated by the laser, resulting in a smooth cut surface without a noticeable recast layer, significantly improving machining quality. However, when applying water-guided laser cutting to the cutting of steel-shell battery flanges, existing fixtures are unsuitable. Therefore, modifications to the existing fixtures are necessary to adapt to water-guided laser cutting. Thus, the development of a water-guided laser cutting fixture suitable for cutting steel-shell battery flanges is required. Utility Model Content

[0004] The purpose of this invention is to provide a water-guided laser cutting fixture to solve the problem that existing fixtures are not suitable for water-guided laser cutting of steel-cased battery flanges.

[0005] To solve the above-mentioned technical problems, this utility model provides a water-guided laser cutting fixture, including a base assembly. The base assembly includes a support base and a mounting base. The support base includes a first support member and a second support member. The first support member and the second support member are both mounted on the mounting base and cooperate to support the workpiece to be processed. The second support member has a structural through groove. The projection of the second support member toward the first support member is located in the structural through groove, and a cutting gap is formed between the inner wall of the structural through groove and the projection of the second support member toward the first support member.

[0006] Optionally, the mounting base has a water collection cavity, and the cutting gap communicates with the water collection cavity of the mounting base.

[0007] Optionally, the water collection cavity is funnel-shaped, with a larger top and a smaller bottom.

[0010] Optionally, the vacuum adsorption plate is provided with vacuum adsorption holes, the vacuum adsorption holes near the outer periphery of the first support member are elongated, and the length direction of the vacuum adsorption holes is perpendicular to the outer periphery of the first support member.

[0011] Optionally, a battery positioning element is mounted on the top of the second support member.

[0012] Optionally, the battery positioning component includes positioning pins mounted on the second support member, with some of the positioning pins positioned along the X direction and some positioned along the Y direction.

[0013] Optionally, it also includes an upper cover assembly that can be raised and lowered in the Z direction and moved in the Y direction relative to the base assembly, the base assembly having a pressing position, and the raising and lowering path of the upper cover assembly passing through the pressing position.

Figure 2 This is a cross-sectional view of the upper cover assembly 200 being pressed onto the base assembly 100 in the water-guided laser cutting fixture of this utility model embodiment. Figure 3This is a partial cross-sectional view of the upper cover assembly 200 being pressed onto the base assembly 100 in the water-guided laser cutting fixture of this utility model embodiment.

Figure 5 This is a schematic diagram of the upper cover assembly 200 in the water-guided laser cutting fixture of this utility model embodiment. This embodiment provides a water-guided laser cutting fixture, including a base assembly 100. The base assembly 100 includes a support base and a mounting base 140. The support base includes a first support member 110 and a second support member 120. The first support member 110 and the second support member 120 are both mounted on the mounting base 140 and cooperate to support the workpiece to be processed. The second support member 120 has a structural through groove 121. The projection of the second support member 120 toward the first support member 110 is located in the structural through groove 121, and a cutting gap is formed between the inner wall of the structural through groove 121 and the projection of the second support member 120 toward the first support member 110.

[0039] Since the second support member 120 and the first support member 110 are used together to support the workpiece to be processed, the base assembly 100 can support the workpiece to be processed. Since the second support member 120 has a structural through groove 121, the projection of the second support member 120 toward the first support member 110 is located in the structural through groove 121, and a cutting gap is formed between the inner wall of the structural through groove 121 and the projection of the second support member 120 toward the first support member 110, thus facilitating the water-guided laser to cut the workpiece to be processed.

[0040] The mounting base 140 has a water collection cavity 141, and the cutting gap 130 communicates with the water collection cavity 141 of the mounting base 140. In this way, the wastewater generated during cutting can be guided into the water collection cavity 141, preventing the wastewater from affecting the normal operation of the mounting fixture.

[0041] The water collection cavity 141 is funnel-shaped, with a larger top and a smaller bottom.

[0042] The base assembly 100 also includes a drain pipe 150, which is connected to the water collection chamber 141.

[0043] The first support member 110 is a vacuum adsorption plate. Vacuum adsorption holes 111 are provided on the vacuum adsorption plate. Preferably, the vacuum adsorption holes 111 near the outer periphery of the first support member 110 are elongated, and the length direction of the vacuum adsorption holes 111 is perpendicular to the outer periphery of the first support member 110. This can stably adsorb the workpiece to be processed while avoiding deformation of the workpiece caused by laser cutting.

[0044] A battery positioning component is mounted on the top of the second support member 120.

[0045] Specifically, the battery positioning component includes positioning pins 161 mounted on the second support 120. Some of the positioning pins 161 are arranged along the X-direction, and some of the positioning pins 161 are arranged along the Y-direction. In this embodiment, there are four positioning pins 161, with two positioning pins 161 arranged along the X-direction and the other two positioning pins 161 arranged along the Y-direction.

[0046] The water-guided laser cutting fixture also includes an upper cover assembly 200 that can move relative to the base assembly 100 in the Z-axis and in the Y-axis. The base assembly 100 has a pressing position, and the lifting path of the upper cover assembly 200 passes through the pressing position. When the upper cover assembly 200 moves in the Z-axis and passes through the pressing position, it can cooperate with the second support member 120 to press the workpiece to be processed, preventing deformation of the workpiece during the cutting process. When the upper cover assembly 200 moves in the Y-axis, it facilitates the loading of the workpiece.

[0047] The water-guided laser cutting fixture also includes a base plate. The upper cover assembly 200 includes a bracket 210, a Y-axis slide rail 220, a lifting frame 230, a Z-axis slide rail 240, and an upper cover plate 250 for cooperating with the second support member 120 to press the workpiece. The Y-axis slide rail 220 is disposed on the base plate. The bracket 210 is slidably connected to the base plate through the Y-axis slide rail 220. The Z-axis slide rail 240 is disposed on the bracket 210. The lifting frame 230 is slidably connected to the bracket 210 through the Z-axis slide rail 240. The upper cover plate 250 is connected to the lifting frame 230. The upper cover plate 250 has a cutting window 260 for the water-guided laser to pass through.

[0048] Preferably, the upper cover assembly 200 further includes a clamping assembly 270 for clamping the cut edge waste. After the workpiece is cut, the clamping assembly 270 can clamp the cut waste and release the waste when the upper cover assembly 200 moves to one side of the base assembly 100.

[0049] Preferably, the number of gripping components 270 is four, and the four gripping components 270 are arranged around the cutting window 260.

[0050] The gripping assembly 270 includes a cylinder 271, a connecting rod, and grippers 272. The cylinder 271 is fixed on the upper cover plate 250. The output end of the cylinder 271 is rotatably connected to the connecting rod. The connecting rod is rotatably connected to the grippers 272. The grippers 272 are rotatably connected to the upper cover plate 250. Thus, the upper cover plate 250, the cylinder 271, the connecting rod, and the grippers 272 form a crank-slider mechanism. The slider (cylinder 271) drives the crank (gripper 272) to rotate in a plane perpendicular to XOY, thereby supporting the edge of the workpiece. The combined action of the grippers 272 of the four gripping assemblies 270 lifts or releases the waste material.

[0051] The second support member 120 is provided with a guide post, and the upper cover plate 250 is provided with a guide sleeve that cooperates with the guide post. In this way, the upper cover plate 250 can be accurately pressed onto the base assembly 100.

[0052] In this embodiment, the working process of the water-guided laser cutting fixture is as follows:

[0053] First, the top cover assembly 200 is moved along the Y direction to one side of the base assembly 100.

[0054] Next, the workpiece to be processed is loaded onto the base assembly 100, and the workpiece is positioned using a battery positioning component.

[0055] Then, the first support 110 vacuum adsorbs the workpiece to be processed.

[0056] Then, the top cover assembly 200 moves along the Y direction to directly above the pressing position of the base assembly 100.

[0057] Then, the upper cover assembly 200 is pressed down to the pressing position, pressing the workpiece to be processed onto the base assembly 100.

[0058] Then, the workpiece is cut using a water-guided laser.

[0059] Then, the clamping component 270 moves to clamp the cutting waste material of the workpiece to be processed.

[0060] Then, the top cover assembly 200 is lifted upwards along the Z-axis.

[0061] Then, repeat the above steps to complete the water-guided laser cutting of the next workpiece.

[0062] The workpiece to be processed in this embodiment is a steel-cased battery.

[0063] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
