DETAILED DESCRIPTION

[0063] The following will be combined with the specific implementation of the present invention to clearly and completely describe the technical solution in the present invention. Obviously, the described implementation is only a part of the implementation of the present invention, not all of the implementation. Based on the implementation of the present invention, all other implementations obtained by ordinary technicians in this field without creative work 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 emission 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 is used to cut the surface of the air-conditioning accessory to remove the material on the surface of the air-conditioning accessory, and then form a deeper groove or pattern on the surface of the air-conditioning accessory to achieve the production purpose, wherein the air-conditioning accessory is a metal accessory, such as a metal laser engraving pressure touch central air-conditioning thermostat panel disclosed in CN214038989U, or other plate-like structure air-conditioning 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 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 the positioning platform 1 includes a body 11, a vacuum pump 12 and a solenoid valve 13. 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 chamber 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-light-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, and the 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 in a vacuum state through the vacuum pump 12, so that the flexible positioning pad 111 is elastically deformed inside the bottom groove 101, and the flexible positioning pad 111 is closely attached to the bottom groove 101, forming a positioning groove 103 for placing the product. Placing the product through the positioning groove 103 can achieve anti-collision protection.

[0069] After laser irradiation, the solenoid valve 13 is opened, 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 the product is pushed out of the bottom groove 101 by the rebound force, which facilitates the removal of the product. Further, in order to quickly reset the flexible positioning pad 111 and provide a large thrust, such as 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. When the product is pushed out, the blower stops, and the flexible positioning pad 111 rebounds to the initial state by its own elastic force. During the 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 to the notch of the bottom groove 101.

[0071] In the above vacuum structure, Figure 5 As shown, the body 11 is provided with a second vacuum chamber 104, and the bottom of the bottom groove 101 is provided with a connecting hole 105. 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 air extraction hole 106 and an air filling hole 107. The air extraction hole 106 is connected to the air inlet of the vacuum pump 12 through a pipeline. The electromagnetic valve 13 is screwed into the air filling hole 107. When vacuuming, the electromagnetic valve 13 is closed, the vacuum pump 12 is powered on, and the first vacuum chamber 102 and the second vacuum chamber 104 are vacuumed through the air extraction hole 106. When releasing the vacuum, the air vacuum pump 12 is stopped, the electromagnetic valve 13 is opened, and the air enters the first vacuum chamber 102 and the second vacuum chamber 104 from the air filling hole 107.

[0072] To facilitate ventilation, Figure 5 As shown, the interior of the body 11 is provided with a housing chamber 108, and the side of the housing chamber 108 is provided with an air inlet grille 1081. The housing chamber 108 is connected to the outside of the body 11 through the air inlet grille 1081, and the air inlet grille 1081 is used to realize ventilation inside the housing chamber 108, and the air inlet grille 1081 is used to realize heat dissipation of the vacuum pump 12. In addition, the vacuum pump 12 and the solenoid valve 13, i.e., the blower, are both arranged in the housing chamber 108, and the blower is arranged below the solenoid valve 13.

[0073] During laser lithography, 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, and 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 different colors from the body 11 and the rubber strip 14, which is convenient for distinguishing various 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] Furthermore, if Figure 7 As shown, a plurality of countersunk holes 109 are provided on the bottom of the bottom groove 101, and a backlight 15 is embedded in each countersunk hole 109. Through the backlight 15, the flexible positioning pad 111 and the backlight 15 form a backlight plate structure. Through the backlight plate structure, it is convenient for the operator to determine the position of the bottom groove 101, making the pre-positioning of the product 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 forms a new positioning groove 103 in accordance with the shape of the bottom groove 101. 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 plurality of hemispherical protrusions 1101, such as Fig. 9As shown, the radius of the plurality of protrusions 1101 increases from the middle 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 plurality of protrusions 1101 in a straight line front and back 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, during the displacement of the protrusion 1101, the product will be slightly displaced, so that the product is centered relative to the bottom groove 101. After being centered, the product can sink into the positioning groove 103 more accurately. 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 make the product not easy to shift 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 and processing of the equipment compatible with such shapes of air conditioning accessories, such as Figure 7 As shown, a bottom groove 101 is provided at the top and the back of the body 11, wherein the rear end of the bottom groove 101 at the top is connected to the top end of the bottom groove 101 at the back, and the groove bottoms of the two bottom grooves 101 are connected in an arc-shaped transition. The flexible positioning pad 111 is L-shaped and covers the notch of the bottom groove 101. When cutting, one end of the L-shaped product is placed on the flexible positioning pad 111 at the top, and the other end is placed on the back of the body 11.

[0078] In actual application, L-shaped air conditioner accessories are prone to slipping 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, and 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 an L-shaped air conditioning accessory, the rear end of the base 2 is driven to warp up 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 further includes a movable plate 16, wherein the movable plate 16 is L-shaped, and a movable plate 16 is respectively arranged on the groove wall on the left and right sides of the bottom groove 101. The movable plate 16 is retractably arranged on the groove wall of the bottom groove 101 at the corresponding position, and the bottom surface of the movable plate 16 is slidably connected to the groove bottom of the bottom groove 101. The spacing between the two movable plates 16 is adjusted by retracting, so that the bottom groove 101 meets the processing requirements of the product.

[0080] In the telescopic structure, a slide groove 1010 is respectively arranged on the groove wall on the left and right sides of the bottom groove 101, and the movable plate 16 is slidably arranged in the slide groove 1010 at the corresponding position, and a slider 17 is arranged on each movable plate 16. The slider 17 is L-shaped, and the bending part of the slider 17 is arranged inside the second vacuum chamber 104. A path hole 1011 is arranged on the groove bottom of the two bottom grooves 101 and at the position corresponding to the slider 17. The two ends of the slider 17 respectively penetrate the path holes 1011 on the two bottom grooves 101 to the slide groove 1010, and the slider 17 can slide left and right along the path hole 1011. The two ends of the slider 17 arranged 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 arranged outside the body 11.

[0082] In addition, an electric cross slide can be arranged 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, wherein 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 which the movable plate 16 blocks the light below it, and use the backlight and the length scale line 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, placing the product on the bright area of ​​the flexible positioning pad 111, and aligning the front end of the product with the rear end of the rubber strip 14 to achieve pre-positioning of the product;
