Abstract
Description

[0002] Currently, in the field of display shell marking, common marking methods include screen printing, inkjet coding and traditional laser marking. Screen printing transfers ink to the surface of the display shell to form a mark by making a printing plate, while inkjet coding uses a nozzle to spray ink onto the shell for marking. Both screen printing and inkjet coding require the use of ink, which is not only expensive, but also may contain harmful chemicals in the ink, which poses a potential threat to the environment and the health of operators. Therefore, laser marking machines are used.

However, due to dust generated during the marking process, the protective lens needs to be replaced regularly or temporarily to maintain the light quality. The common replacement method is to manually take out the lens from the tool box, then remove the old lens, and then reinstall the new lens. This method is cumbersome to find the lens and disassemble and reinstall the lens, and it takes a long time.

DETAILED DESCRIPTION
[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0027] Example 1, reference Figure 1 to Figure 7, which is the first embodiment of the present invention, and provides an efficient laser marking device for a display housing, which can realize automatic replacement of a protective lens 106 of a laser marking machine, and improve the replacement efficiency. The device comprises a supporting component 100, including a sliding frame 101, a moving platform 102 arranged on the sliding frame 101, a lifting platform 103 arranged on the moving platform 102, a laser emitter 104 arranged on the front side of the lifting platform 103, a ring 105 arranged on the laser emitter 104, a protective lens 106 arranged in the ring 105, and a rotatable The rotating fixture 107; the replacement component 200, including a power component 201 arranged on the lifting platform 103, a clamping component 202 arranged on the power component 201, a guide component 203 arranged on the clamping component 202, and a replenishment component 204 arranged on the lifting platform 103; the automatic replenishment component 300, including a pump air component 301 arranged on the power component 201, and an extrusion component 302 arranged on the pump air component 301; the loading component 400, including a pressure relief component 401 arranged on the replenishment component 204, and a feeding component 402 arranged on the replenishment component 204.
[0028] Specifically, the moving platform 102, the lifting platform 103, the laser transmitter 104, the protective lens 106, the ring 105, etc. are combined into a laser marking machine. The protective lens 106 is in front of the field lens and is used to protect the field lens from dust and other impurities. Since dust will be generated during the marking process, the protective lens 106 needs to be replaced regularly to maintain the light quality. The laser marking machine here is a prior art and will not be described in detail here.
[0029] Furthermore, the power assembly 201 includes a connecting column 201a fixedly connected to the lifting platform 103, the connecting column 201a is fixedly connected to the laser emitter 104, a motor 201b is fixedly connected to the connecting column 201a, and a rotating plate 201c is fixedly connected to the output shaft of the motor 201b; two mounting grooves 202b are provided on the rotating plate 201c, and electromagnets 202c are fixedly connected to the inner walls of the two mounting grooves 202b, and iron mounting frames 202d are slidably connected in the two mounting grooves 202b, and a slider 202f is slidably connected in the mounting frame 202d, an L-shaped rod 202g is fixedly connected to the slider 202f, and a transfer block is fixedly connected to the L-shaped rod 202g, and a second arc plate 202h that cooperates with the first arc plate 202a is fixedly connected to the transfer block, and the mounting frame 202d is elastically connected to the inner wall of the mounting groove 202b through a first spring 202i.
[0030] Among them, the output shaft of the motor 201b here has damping and can automatically achieve self-locking, thereby preventing the output shaft of the motor 201b from rotating and driving the ring 105 to rotate during use, causing the protective lens 106 to shift. The first arc plate 202a and the second arc plate 202h cooperate to clamp the ring 105. The elasticity of the first spring 202i here is sufficient to ensure that the first arc plate 202a and the second arc plate 202h can clamp the ring 105. The permanent magnet 202e and the electromagnet 202c are set here. When the electromagnet 202c is energized, the permanent magnet 202e and the electromagnet 202c are separated. When the electromagnet 202c is powered off, the electromagnet 202c and the permanent magnet 202e can be adsorbed, so that the first arc plate 202a and the second arc plate 202h clamp the ring 105 more stably.
[0031] Preferably, the guide assembly 203 includes a transverse groove 203a arranged in the mounting groove 202b, the transverse groove 203a is connected to an arc groove 203b, and an L-shaped rod 202g passes through the slider 202f and cooperates with the transverse groove 203a; the replenishment assembly 204 includes a mounting box 204a fixedly connected to the lifting platform 103, two extension plates 204b are fixedly connected to the mounting box 204a, a plurality of substitute frames and substitute lenses 204c are arranged in the mounting box 204a, a substitute lens 204c is located between the two extension plates 204b, and the lower end surface of the upper extension plate 204b is fixedly connected to an elastic strip 204d with an arc edge.
[0032] It should be noted that the length of the transverse groove 203a here is greater than the distance between the first curved plate 202a and the edge of the extension plate 204b, thereby avoiding the jamming phenomenon between the second curved plate 202h and the extension plate 204b. The setting of the elastic strip 204d here ensures that when the substitute lens 204c is pushed outward, it can avoid deviation and separation from the extension plate 204b. At the same time, the lens here does not extend to the outside of the extension plate 204b to avoid being contaminated by dust, etc. The substitute lens 204c and the protective lens 106 here do not refer to a single one. As long as it is on the lower side of the laser emitter 104, it is the protective lens 106, and the others are substitute lenses 204c.
[0033] When in use, after the rotatable clamp 107 clamps the display screen housing, the display screen housing can be rotated, so that curved surfaces or special-shaped surfaces can be marked. When the protective lens needs to be replaced, it is only necessary to start the motor 201b to rotate the output shaft of the motor 201b, and then the rotating plate 201c is deflected. When the rotating plate 201c is deflected, the protective lens on the lower side of the laser emitter 104 can be moved out, and the replacement lens on the extension plate 204b can be rotated to the lower side of the laser emitter 104 to achieve the replacement of the protective lens 106. Here, a waste box can be placed on the left side of the laser emitter 104. When the protective lens 106 moves to the waste box When the electromagnet 202c is on the upper side, the electromagnet 202c is energized, so that the permanent magnet 202e and the electromagnet 202c repel each other and separate, so that the installation frame 202d moves in the direction away from the electromagnet 202c, so that the slider 202f moves in the direction away from the electromagnet 202c, and the L-shaped plate 301a moves in the direction away from the electromagnet 202c. The second arc plate 202h is separated from the first arc plate 202a through the transmission of the adapter block. At this time, the ring 105 lacks clamping and falls into the waste box. At this time, the electromagnet 202c continues to be energized, and one of the replacement lenses 204c in the installation box 204a is pushed onto the extension plate 204b (the specific pushing method, embodiment 2 will be described in detail), since the electromagnet 202c continues to be energized, when the slider 202f moves, the L-shaped rod 202g slides in the horizontal groove 203a, and then enters the arc groove 203b, so that the L-shaped rod 202g moves downward. When the L-shaped rod 202g moves downward, it can drive the adapter block to move downward, so that the second arc plate 202h moves downward. In this way, when the second arc plate 202h moves to the extension plate 204b position, it passes from the lower side of the extension plate 204b and will not sweep off the replacement lens 204c on the extension plate 204b. At this time, the second arc plate 202h is separated from the first arc plate 202a, and the first arc plate 202a is in the position of When replacing the left side wall of the lens 204c, the second curved plate 202h is on the right side of the extension plate 204b, and there is a gap with the right side of the extension plate 204b. Then the electromagnet 202c is powered off, and under the action of the first spring 202i, the mounting frame 202d is reset, driving the L-shaped rod 202g to reset. At this time, the L-shaped rod 202g first slides in the arc groove 203b, and then slides in the transverse groove 203a, so that the second curved plate 202h first moves upward to a position flush with the first curved plate 202a, and then the second curved plate 202h faces the first curved plate 202a, and cooperates with the first curved plate 202a to clamp the replacement frame for the next replacement.
[0034] In summary, by providing the supporting component 100 and the replacement component 200, the protective lens 106 can be automatically replaced, and after the protective lens 106 is replaced, the replacement lens 204c can be automatically clamped, so that after the protective lens 106 is damaged again, it can continue to be automatically replaced, thereby eliminating the need for workers to look for lenses to replace, improving replacement efficiency, reducing replacement waiting time, and improving the efficiency of the laser marking machine.
[0035] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an automatic replacement component 300 for a high-efficiency laser marking device for a display housing, which solves the problem of how to automatically push the replacement lens 204c at the rear end of the installation box 204a to the front end. It includes a pump assembly 301, including an L-shaped plate 301a fixedly connected to the motor 201b, a pump cylinder 301b with a front end opening fixedly connected to the L-shaped plate 301a, a first pipeline 301c is sealed on the pump cylinder 301b, a piston 301d is sealed and slidably connected in the pump cylinder 301b, the piston 301d is elastically connected to the inner wall of the pump cylinder 301b through a second spring, and a plunger 301e is fixedly connected to the piston 301d. The extrusion assembly 302 includes a guide plate 302a fixedly connected to the output shaft of the motor 201b and cooperating with the plunger 301e, a cutting edge 302b is provided on the guide plate 302a, a sealing box 302c with an open front end is fixedly connected to the mounting box 204a, the sealing box 302c is sealed and connected to the pump cylinder 301b through a second pipe 302d, a one-way valve is provided in the first pipe 301c and the second pipe 302d, a sliding plug is sealingly and slidably connected in the sealing box 302c, a U-shaped rod 302e is fixedly connected to the sliding plug, a circular opening for the U-shaped rod 302e to pass through is provided on the mounting box 204a, a push plate 302f is slidably connected in the mounting box 204a, and the U-shaped rod 302e is fixedly connected to the push plate 302f.
[0036] Specifically, the one-way valve in the first pipe 301c here only allows gas to enter the pump cylinder 301b from the outside, thereby realizing one-way air intake, and the one-way valve in the second pipe 302d only allows gas to enter the sealing box 302c from the pump cylinder 301b, thereby realizing one-way exhaust.
[0037] When in use, when the output shaft of the motor 201b rotates, the guide plate 302a can be driven to rotate around the output shaft of the motor 201b. When the cut edge 302b on the guide plate 302a abuts against the plunger 301e, the first arc plate 202a and the second arc plate 202h move out from the extension plate 204b. At this time, the movement continues, the guide plate 302a abuts against the plunger 301e, so that the plunger 301e moves outward, the piston 301d moves, and the gas in the pump cylinder 301b is pumped into the sealing box 302c, so that the sliding plug moves, driving the U-shaped rod 302e toward the extension plate 20 4b direction, so that the push plate 302f moves toward the extension plate 204b, driving the replacement lens 204c to move. It should be noted here that the bottom of the replacement frame is at the lower side of the replacement lens 204c, so that when the replacement lens 204c moves, the replacement frame and the inner wall of the installation box 204a rub against each other, which will not cause wear of the replacement lens 204c. The plunger 301e is arranged here to push the piston 301d to generate gas to push the U-shaped rod 302e to move a distance of the replacement frame diameter, thereby ensuring that the new replacement lens 204c is pushed onto the extension plate 204b.
[0038] In summary, by setting up the automatic filling component 300, when the output shaft of the motor 201b rotates to replace the protective lens 106, it can also automatically drive multiple substitute lenses 204c to move, and automatically fill in the substitute lens 204c after the substitute lens 204c on the extension plate 204b is moved out.
[0039] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a feeding component 400 for a high-efficiency laser marking device for a display housing, which solves the problem of how to feed a replacement lens 204c in an installation box 204a. It includes a pressure relief component 401, including a third pipe 401a fixedly connected to a sealing box 302c, a valve 401b is provided on the third pipe 401a, and a sliding plug is elastically connected to the inner wall of the sealing box 302c through a third spring 401c. The feeding component 402 includes an opening arranged on the side wall of the installation box 204a, an inner groove 402a is provided on the opening, and a plurality of cylinders 402b are interference-fitted in the inner groove 402a, a protective plate 402c is fixedly connected to the cylinder 402b, and a handle is fixedly connected to the protective plate 402c.
[0040] Specifically, the initial state of the valve 401b here is a closed state, so as not to cause leakage of the air pressure in the sealing box 302c. A lock that cooperates with the installation box 204a can also be set on the protective plate 402c, and the protective plate 402c is fixed by the lock. The limiting method of the protective plate 402c here is not unique, as long as the protective plate 402c can be limited and the disassembly of the protective plate 402c is convenient.
[0041] During use, when it is necessary to load the replacement lens 204c in the installation box 204a (a check can be performed every week. After the replacement lens 204c in the installation box 204a is used up, there is still a replacement lens 204c left on the extension plate 204b, and the replacement lens 204c needs to be replenished), just open the valve 401b. At this time, the third pipe 401a is exhausted, and the slide plug is reset under the action of the third spring 401c, so that the U-shaped rod 302e is reset and the push plate 302f is reset. At this time, the replacement lens 204c can be placed on the front side of the push plate 302f, and then the handle is pulled to separate the protective plate 402c from the installation box 204a. At this time, the replacement lens 204c can be directly placed in the installation box 204a to replenish the replacement lens 204c for next use.
[0042] In summary, by setting up the loading component 400, after the multiple replacement lenses 204c in the installation box 204a are consumed, it is only necessary to turn the valve 401b and then pull the handle to separate the protective plate 402c from the installation box 204a, and then the replacement lenses 204c in the installation box 204a can be directly replenished.
[0043] Embodiment 4 is the fourth embodiment of the present invention. Different from the previous embodiment, this embodiment provides an efficient laser marking method for a display housing, including adjusting the position of the laser emitter 104 by sliding the movable table 102; the laser emitter 104 emits a laser for marking; the laser emitter 104 stops waiting for the protective lens 106 to be replaced; the output shaft of the motor 201b rotates to swap the protective lens 106 with the substitute lens 204c; and after completing the replacement of the protective lens 106, the marking continues.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
