[0045] The laser engraving device for air conditioner accessories of the present invention has the following beneficial effects compared with the prior art:

[0046] (1) A positioning groove for placing the product is formed inside the bottom groove by a flexible positioning pad, so that the surface of the product is not easily indented or deformed, which can effectively reduce the scrap rate. At the same time, the product in the bottom groove is pushed out by the rebound of the flexible positioning pad, which facilitates the disassembly of the product and improves the convenience of the cutting work. In addition, by setting up a blower to blow air, it is easy to drive the flexible positioning pad to return to its position quickly, thereby increasing the thrust of the flexible positioning pad, so that the product can be quickly pushed out of the bottom groove, and the efficiency of the product disassembly work is improved.

[0047] (2) The provision of the rubber strip and backlight panel structure facilitates the initial positioning of the product, making it easier for the staff to place the product more accurately into the positioning groove formed after vacuuming, thereby improving work efficiency.

[0048] (3) By setting the protrusions, it is convenient to protect the surface of the flexible positioning pad, so that the surface of the flexible positioning pad is not easily damaged by the product. At the same time, by setting the radius of the protrusions to increase from the middle of the bottom groove to the left and right sides, it is convenient to drive the product to move slightly by the protrusions, and facilitate the product to move toward the center of the bottom groove, thereby facilitating the product to sink into the positioning groove more accurately for positioning. In addition, after the product is positioned, the protrusions on the left and right sides of the bottom groove can support the side of the product to stabilize the product, making it difficult for the product to shift during the cutting process, thereby improving the cutting quality.

[0049] (4) By providing a bottom groove on the top and back of the main body, the bottom groove is formed into an L shape as a whole, which facilitates surface cutting of L-shaped products and improves the applicability of the equipment. At the same time, by providing an electric telescopic rod, it is easy to tilt the main body forward, so that the L-shaped product placed on the flexible positioning pad can be tilted forward without sliding, making it easier for workers to accurately place the L-shaped product into the positioning groove formed after vacuuming, thereby improving work efficiency.

[0050] (5) By setting the movable plate to be retractable on the groove wall of the bottom groove at the corresponding position, the width of the bottom groove can be adjusted, so that the device can be compatible with products of different widths, thereby making the application range of the device wider.

[0051] (6) By setting the bottom of the bottom groove and the movable plate in sliding connection, the movable plate is pressed against the bottom of the bottom groove, so that the flexible positioning pad can press against the top surface and side surface of the movable plate and the bottom of the bottom groove well when vacuuming, which is beneficial to improving the accuracy of the positioning groove molding.

[0063] The following will be combined with the specific embodiments of the present invention to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0064] like Figure 1-9 As shown, a laser engraving device for air conditioner accessories of the present invention includes a positioning platform 1, a base 2 and a laser 3.

[0065] The positioning platform 1 and the laser 3 are respectively arranged on the base 2, and the emitting end of the laser 3 is arranged above the positioning platform 1. The laser 3 is used to emit a laser beam in the direction of the positioning platform 1 to cut the metal product. That is, the laser 3 cuts the surface of the air conditioner accessory to remove the material on the surface of the air conditioner accessory, thereby forming a deeper groove or pattern on the surface of the air conditioner accessory to achieve the production purpose. The air conditioner accessory is a metal accessory, such as the metal laser engraved pressure touch central air conditioner thermostat panel disclosed in CN214038989U, or other plate-like air conditioner metal accessories.

[0066] The function of the positioning table 1 is to clamp the workpiece to cooperate with the laser 3 for laser cutting. Figure 1 The positioning platform 1 shown is rectangular in shape, and the front end of the laser 3 is the emitting end, which is suspended above the positioning platform 1 and is used to emit laser light downward.

[0067] like Figure 1 As shown, the positioning platform 1 includes a body 11, a vacuum pump 12 and a solenoid valve 13. The body 11 is arranged on the base 2, and is combined with Figure 3-8The top of the body 11 is provided with a bottom groove 101, and the notch of the bottom groove 101 is covered and fixed with a flexible positioning pad 111, and a closed first vacuum cavity 102 is formed between the flexible positioning pad 111 and the bottom groove 101. The flexible positioning pad 111 is made of silicone or TPU, which can be elastically deformed and can be light-transmissive or semi-transmissive. In the initial state, Figure 4 As shown, the flexible positioning pad 111 is in the shape of a flat plate.

[0068] like Figure 5 As shown, the vacuum pump 12 and the electromagnetic valve 13 are fixed on the body 11, combined with Figure 8 When a product needs to be placed, the solenoid valve 13 is closed, and the interior of the first vacuum chamber 102 is vacuumed by the vacuum pump 12. This causes the flexible positioning pad 111 to elastically deform within the bottom groove 101 and cling to the bottom groove 101, forming a positioning groove 103 for placing the product. Placing the product in this positioning groove 103 provides protection against knocks.

[0069] After laser irradiation, the electromagnetic valve 13 opens, and air enters the first vacuum chamber 102, releasing the vacuum state of the first vacuum chamber 102. At this time, the flexible positioning pad 111 rebounds and resets, and pushes the product out of the bottom groove 101 by the rebound force, which facilitates the removal of the product. Furthermore, in order to quickly reset the flexible positioning pad 111 and provide a large thrust, as shown in FIG. Figure 5 As shown, one end of the solenoid valve 13 is connected to the blower, and the other end is connected to the first vacuum chamber 102. The blower is arranged on the main body 11. The blower is used to blow air into the first vacuum chamber 102 to release the vacuum state of the first vacuum chamber 102, and drive the flexible positioning pad 111 to rebound and reset, and then the product is quickly pushed out of the bottom groove 101 through the flexible positioning pad 111, thereby improving the disassembly efficiency. After the product is pushed out, the blower stops, and the flexible positioning pad 111 rebounds to its initial state by its own elastic force. During this process, the outside air can still pass through the blower and the solenoid valve 13 into the first vacuum chamber 102, because the blower itself is not a sealed structure. When the flexible positioning pad 111 is reset, the solenoid valve 13 is closed.

[0070] Since the flexible positioning pad 111 is made of silicone or TPU, it is not easily damaged by the product. When the flexible positioning pad 111 is damaged during use, the damaged flexible positioning pad 111 is removed, and then a new flexible positioning pad 111 is pasted and fixed on the notch of the bottom groove 101.

[0071] In the above vacuum structure, Figure 5 As shown, a second vacuum chamber 104 is provided inside the body 11, and a connecting hole 105 is provided on the bottom of the bottom groove 101. The second vacuum chamber 104 is connected to the first vacuum chamber 102 through the connecting hole 105. Figure 5As shown, the second vacuum chamber 104 is provided with an exhaust hole 106 and an air filling hole 107. The exhaust hole 106 is connected to the air inlet of the vacuum pump 12 via a pipe. The solenoid valve 13 is screwed into the air filling hole 107. During vacuuming, the solenoid valve 13 is closed, and the vacuum pump 12 is powered on, evacuating the first vacuum chamber 102 and the second vacuum chamber 104 through the exhaust hole 106. During de-vacuuming, the vacuum pump 12 is shut down, the solenoid valve 13 is opened, and air enters the first vacuum chamber 102 and the second vacuum chamber 104 through the air filling hole 107.

[0072] To facilitate ventilation, Figure 5 As shown, the body 11 has a housing chamber 108 disposed therein, with an air inlet grille 1081 disposed on the side of the housing chamber 108. The air inlet grille 1081 connects the housing chamber 108 to the exterior of the body 11, allowing ventilation within the housing chamber 108 and dissipating heat from the vacuum pump 12. Furthermore, the vacuum pump 12 and the solenoid valve 13, i.e., the blower, are both disposed within the housing chamber 108, with the blower disposed below the solenoid valve 13.

[0073] During laser irradiation, the product is pre-placed on the top of the body 11. To facilitate positioning, a rubber strip 14 is fixed on the top of the body 11. Figure 5 As shown, the rear end of the rubber strip 14 is aligned with the front end of the bottom groove 101. When placing the product, align the front end of the product with the rubber strip 14. After alignment, place the product on the flexible positioning pad 111 to facilitate pre-positioning of the product.

[0074] Furthermore, the flexible positioning pad 111 is of a different color from the body 11 and the rubber strip 14, making it easier to distinguish between different parts and making the pre-positioning of the product more convenient and accurate. In addition, the rubber strip 14 is provided with length scale lines.

[0075] Further, if Figure 7 As shown, the bottom of the bottom groove 101 is provided with a plurality of countersunk holes 109, each of which is embedded with a backlight 15. The backlight 15 forms a backlight panel structure with the flexible positioning pad 111. This backlight panel structure facilitates the operator's determination of the position of the bottom groove 101, making product pre-positioning more convenient and accurate.

[0076] After positioning, the flexible positioning pad 111 is recessed into the bottom groove 101 under the action of vacuum, and conforms to the shape of the bottom groove 101 to form a new positioning groove 103. The formed positioning groove 103 matches the shape of the product. During the process, the pre-positioned product slowly sinks into the positioning groove 103 to achieve final positioning. In order to correct the position of the product, the outer surface matrix of the flexible positioning pad 111 is provided with a number of hemispherical protrusions 1101, among which, Figure 9As shown, the radius of the protrusions 1101 increases from the center of the bottom groove 101 to the left and right sides, that is, the radius of the protrusion 1101 in the middle is the smallest, and the radius of the protrusions 1101 on both sides increases outward, and the radius of the protrusions 1101 in a straight line are equal. When the flexible positioning pad 111 is concave, it will drive the protrusion 1101 to move toward the center of the bottom groove 101. Therefore, the displacement of the protrusion 1101 will cause the product to move slightly, so that the product is centered relative to the bottom groove 101. After being centered, the product can be sunk more accurately into the positioning groove 103. After sinking, the protrusions 1101 on the left and right sides of the bottom groove 101 can support the side of the product, stabilize the product, and prevent the product from shifting during the cutting process, thereby improving the cutting quality.

[0077] The above structure is suitable for the cutting and processing of plate-shaped air-conditioning accessories. However, since air-conditioning accessories are not only plate-shaped, but also L-shaped plate-shaped air-conditioning accessories, in view of this, in order to improve the surface cutting processing of the equipment that can be compatible with this shape of air-conditioning accessories, such as Figure 7 As shown, a bottom groove 101 is provided on the top and back of the body 11. The rear end of the top groove 101 communicates with the top end of the back groove 101, and the bottoms of the two grooves 101 form an arc-shaped transition where they meet. An L-shaped flexible positioning pad 111 covers the notch of the bottom groove 101. When cutting, place one end of the L-shaped product on the top flexible positioning pad 111 and the other end on the back of the body 11.

[0078] In actual application, L-shaped air conditioner accessories are easy to slip after placement, affecting the accurate positioning of the product. In order to facilitate the installation and positioning of such air conditioner accessories, Figure 1-2 As shown, a linear lifting module 6 is fixed on the top of the base 2, and the linear lifting module 6 is arranged on the rear side of the main body 11. The laser 3 is fixed on the output end of the linear lifting module 6, and the height adjustment of the laser 3 is achieved through the linear lifting module 6, wherein the linear lifting module 6 is any electric linear slide or manual linear slide with a lifting function in the prior art, and is not specifically limited. At the same time, the bottom of the base 2 is arranged on the top of the base 4, and the front end of the base 2 is hinged to the front end of the base 4. And an electric telescopic rod 5 is arranged between the base 2 and the base 4, one end of the electric telescopic rod 5 is hinged to the rear end of the base 2, and the other end is hinged to the rear end of the base 4. When it is necessary to place L-shaped air-conditioning accessories, the rear end of the base 2 is driven to warp upward by the electric telescopic rod 5, so that the bottom groove 101 tilts forward. In this state, the product can be placed on the main body 11 more stably.

[0079] At the same time, in actual application, the width of air conditioning accessories is also different. In order to adapt to the laser processing of products with different widths, such as Figure 3-8As shown, the positioning platform 1 also includes a movable plate 16. The movable plate 16 is L-shaped and is positioned on each of the left and right sides of the bottom groove 101. The movable plates 16 are retractably mounted on the corresponding groove walls of the bottom groove 101, with the bottom surfaces of the movable plates 16 slidingly connected to the bottom of the bottom groove 101. The spacing between the two movable plates 16 can be adjusted by retracting and extending the movable plates 16, ensuring that the bottom groove 101 meets the processing requirements of the product.

[0080] In this telescopic structure, a slide groove 1010 is provided on the left and right sides of the bottom groove 101. The movable plate 16 slides in the corresponding slide groove 1010. Each movable plate 16 is provided with a slider 17. The slider 17 is L-shaped, with the bent portion of the slider 17 located within the second vacuum chamber 104. A path hole 1011 is provided on the bottom of each bottom groove 101, corresponding to the position of the slider 17. The two ends of the slider 17 extend through the path holes 1011 of the two bottom grooves 101 and into the slide groove 1010. The slider 17 can slide left and right along the path holes 1011. The two ends of the slider 17, which are located in the slide groove 1010, are fixedly connected to the movable plate 16.

[0081] A screw rod 18 is horizontally passed through the bent portion of each slider 17, wherein the screw rod 18 is screwed to the slider 17. One end of the screw rod 18 passes through the side of the body 11 and is fixedly connected to a knob 19, which is provided on the outside of the body 11.

[0082] In addition, an electric cross slide can be set between the linear lifting module 6 and the base 2 to adjust the left and right position and the front and back position of the laser 3. The electric cross slide is not shown in the figure.

[0083] When using the laser engraving device for air conditioner accessories of the present invention, the following steps are included:

[0084] S1. Turn on the backlight 15 to illuminate the flexible positioning pad 111. Turn the knob 19 to translate the movable plate 16. During this process, the movable plate 16 blocks the light below it. Use the backlight and the length scale lines on the rubber strip 14 to observe the width change of the bright part of the flexible positioning pad 111 to determine the distance between the two movable plates 16.

[0085] S2. Place the product on the bright area of ​​the flexible positioning pad 111 and align the front end of the product with the rear end of the rubber strip 14 to achieve pre-positioning of the product;

[0086] S3. Close the solenoid valve 13 and turn on the vacuum pump 12 to allow the flexible positioning pad 111 to recess downward into the bottom groove 101. During this process, hold the product by hand and slightly move it so that it can be accurately moved into the positioning groove 103 formed by the flexible positioning pad 111 to achieve final positioning of the product. Then, turn off the vacuum pump 12 and maintain the vacuum state of the first vacuum chamber 102 before proceeding with the surface cutting operation.

[0087] S4. After cutting, the electromagnetic valve 13 is opened to release the vacuum state of the first vacuum chamber 102. The flexible positioning pad 111 rebounds and pushes out the product sunk in the bottom groove 101, thereby realizing product disassembly.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
