Description

Technical fields:

[0001] This utility model belongs to the field of laser cutting equipment, and in particular relates to a laser processing device. Background technology:

[0002] With the increasing demand for power batteries in new energy vehicles, the processing efficiency and precision requirements for flow channel plates, as heat-conducting components, are constantly rising. Traditional laser cutting of flow channel plates results in excess material due to the need for pre-reserved anti-deformation ribs, and irregular shapes make positioning difficult, making it hard to guarantee the positional accuracy of holes, shapes, and flow channels. Existing solutions include: 1) Laser scanning positioning, but this method is inefficient, requiring scanning every time the product is placed, especially with large flow channel plates, where scanning is time-consuming and prone to errors; 2) Temporary fixture method, which requires on-site laser cutting of the substrate and bonding of positioning pins, resulting in poor overall positioning accuracy, and the fixture cannot be reused, requiring remanufacturing during production changes, leading to high costs and low efficiency. Utility model content:

[0003] To address the aforementioned issues of low overall performance and poor positioning accuracy in laser-cut flow channel plates, this invention proposes a laser processing device.

[0004] The laser processing device provided by this utility model includes a laser machine base, a cutting laser head, an operation panel, a CNC moving track, and a fixture assembly. Its characteristic is that it also includes a crossbeam with multiple sets of positioning holes and at least one reference positioning hole. The center coordinates of the reference positioning hole and the zero-point reference coordinates of the cutting laser head have a preset coordinate mapping relationship. After the cutting laser head returns to zero, the zero-point reference and the center coordinates of the reference positioning hole maintain the preset coordinate mapping relationship.

[0005] As a further improvement of this utility model, the center of the crossbeam is a cross-shaped structure, and the reference positioning hole is located at the center of the cross-shaped structure of the crossbeam.

[0006] As a further improvement of this utility model, the crossbeam is fixedly connected to the laser machine base.

[0007] As a further improvement of this utility model, the positioning holes are arranged at equal intervals.

[0008] As a further improvement of this utility model, the clamping assembly includes a base plate, a guide pin, a suction cup, a rotating pneumatic rod pressure plate, and an alignment hole, the position of which corresponds to the positioning hole.

[0009] As a further improvement of this utility model, the number of guide pins is four, and the four guide pins are respectively located at the four corners of the base plate.

[0010] As a further improvement of this utility model, the clamping assembly also includes a positioning pin, which passes through the alignment hole and the positioning hole and is connected to the crossbeam.

[0011] The beneficial effects of this utility model are: by adding multiple sets of positioning holes and reference positioning holes on the crossbeam, and establishing a preset coordinate mapping relationship between the reference positioning holes and the zero point of the cutting laser head, the product to be cut can be positioned with high precision in a short time; the product to be cut can be quickly connected by the clamping assembly, which greatly improves the overall processing efficiency of the product.

[0018] The technical solutions in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. The embodiments are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0020] like Figure 1 , Figure 2 The image shows an embodiment of a laser processing device provided by this utility model, including a laser machine base 1, a cutting laser head 2, a crossbeam 3, an operation panel 4, a CNC moving track 5, a positioning hole 7, a reference positioning hole 8, a base plate 10, a guide pin 12, a suction cup 14, a rotary cylinder pressure plate 16, an alignment hole 18, and a positioning pin 20.

[0021] The crossbeam 3 is fixedly connected to the laser machine base 1. The crossbeam 3 is provided with multiple sets of positioning holes 7 and a reference positioning hole 8. The positioning holes 7 are arranged at equal intervals. The center of the crossbeam 3 is a cross-shaped structure. The reference positioning hole 8 is located at the center of the cross-shaped structure of the crossbeam 3. There is a preset coordinate mapping relationship between the center coordinates of the reference positioning hole 8 and the zero-point reference coordinates of the cutting laser head 2. After the cutting laser head 2 returns to zero, the zero-point reference and the center coordinates of the reference positioning hole 8 maintain the preset coordinate mapping relationship, so that the distance between the positioning hole 7 and the zero point of the cutting laser head 2 remains fixed.

[0022] like Figure 1 , Figure 2 As shown, the base plate 10 is provided with the guide pin 12, the suction cup 14, the rotary cylinder pressure plate 16, the alignment hole 18 and the positioning pin 20. There are four guide pins 12, which are located at the four corners of the base plate 10. There are at least four suction cups 14 and rotary cylinder pressure plates 16. The alignment hole 18 is positioned corresponding to the positioning hole 7. The positioning pin 20 passes through the alignment hole 18 and the positioning hole 7 and is connected to the crossbeam 3.

[0023] The following is combined with Figure 1 and Figure 2 This further clarifies the processing method of the laser processing device of this utility model.

[0024] Step 1: Fix the product 25 to be cut onto the fixture assembly using the guide pins 12 on the base plate 10;

[0025] Step 2: Place the clamp assembly flat on the crossbeam 3, and fix it by passing the positioning pin 20 through the alignment hole 18 and the positioning hole 7;

[0026] Step 3: Control the cutting laser head 2 by operating the operation panel 4, and determine the preset coordinate mapping relationship between the zero point reference coordinate and the center coordinate of the reference positioning hole 8 on the crossbeam 3 through the visual positioning function of the cutting laser head 2, determine the precise cutting range, and cut the product 25 to be cut accordingly.

[0027] Step 4: After the cutting is completed, the cutting laser head 2 returns to zero according to the preset coordinate mapping relationship between the zero point reference and the center coordinates of the reference positioning hole 8.

[0028] After the product is cut, the corresponding product is taken out, and the above steps are repeated for the product that needs to be cut. The cutting laser head 2 will periodically calibrate the coordinate mapping relationship between itself and the reference positioning hole 8 through the visual positioning function to prevent large deviations from occurring during the use of the laser processing device.

[0029] In this embodiment, there is one reference positioning hole 8, which is located at the center of the cross-shaped structure of the crossbeam 3. The positioning holes 7 are arranged at equal intervals. In other embodiments, the number and position of the reference positioning holes 8 can be adjusted according to the requirements. The positioning holes 7 can also be arranged at equal intervals or non-equal intervals according to the requirements. The preset coordinate mapping relationship between the center coordinates of the reference positioning holes 8 on the crossbeam 3 can also be adjusted according to the actual needs of the specific cutting product.

[0030] This invention enables high-precision benchmark positioning of the product to be cut in a short time by adding multiple sets of positioning holes 7 and reference positioning holes 8 on the crossbeam 3, and establishing a preset coordinate mapping relationship between the reference positioning holes 8 and the zero point of the cutting laser head 2; and by quickly connecting the product to be cut through the clamping assembly, the overall processing efficiency of the product is greatly improved.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered as belonging to the present invention.
