Description

Technical Field

[0001] This utility model relates to the field of lens screen printing machine technology, specifically to an antistatic device for a lens screen printing machine. Background Technology

[0002] Lenses are transparent materials with one or more curved surfaces, made of optical materials such as glass or resin. After polishing, they are often assembled with eyeglass frames to make eyeglasses to correct the user's vision and obtain a clear field of vision. A lens screen printing machine is a device used to screen print on the surface of a lens, and it belongs to the printing machine category. An antistatic device for a lens screen printing machine is a device used to eliminate static electricity generated during the lens screen printing process.

[0003] As disclosed in Chinese Patent CN214688454U, a dust removal and static electricity removal device for a lens screen printing machine includes a lifting frame 201 that supports the rotation of an adjusting screw 206 to push a slider 203 to move up and down along a slide groove 202, placing the lens on a tray. A linear motor drives the tray to move along a guide rail, and a lifting cylinder drives the lifting frame to move down. A first bracket is fixed to the slider via an ear plate and supports a wire brush to discharge static electricity from the lens surface. Alternatively, a second bracket is fixed to the slider and supports a support shaft that rotates to discharge static electricity from the lens surface via a wire brush roller. Then, the support roller presses down on a sticker to adhere dust to the lens surface. Finally, the lens enters the screen printing main body for screen printing. The lifting cylinder drives the lifting frame to rise, and a servo motor drives the support roller to rotate, causing the sticker to move and change position.

[0004] While this structure can remove static electricity and dust from the lens screen printing machine, the device merely places the lens above the slide without fixing it in place. This causes the lens to shift during the static electricity removal and dust removal process, resulting in poor processing stability. Therefore, we propose a static electricity removal device for a lens screen printing machine that can fix the lens in place to prevent it from shifting during processing and thus improve processing stability. Utility Model Content

[0005] The purpose of this invention is to provide an antistatic device for a lens screen printing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an antistatic device for a lens screen printing machine, comprising a tray, a linear motor fixedly mounted on the bottom of the tray, a guide rail slidably mounted on the bottom of the linear motor, and a processing component mounted above the guide rail, the processing component including a fixing component mounted above the guide rail, and an auxiliary component mounted on the side of the fixing component.

[0007] Preferably, the fixing component includes an air tube fixedly installed inside the tray, with a suction cup connected to the end of the air tube, an air rod slidably installed inside the air tube, a pull plate fixedly installed at the end of the air rod, a limit rod fixedly installed on the top surface of the pull plate, a sliding groove formed on the outer wall of the limit rod, a first magnetic block fixedly installed on the inner wall of the sliding groove, a second magnetic block slidably installed inside the sliding groove, and a locking block fixedly installed on the side wall of the second magnetic block.

[0008] Preferably, the auxiliary component includes a fixed plate fixedly installed on the top surface of the tray, a slide rod fixedly installed on the outer wall of the fixed plate, a clamping plate slidably disposed on the outer wall of the slide rod, and a spring fixedly installed on the side wall of the clamping plate.

[0009] Preferably, the first magnetic block and the second magnetic block are magnetically repulsive, and the outer wall of the second magnetic block is slidably disposed inside the groove, so that the block is pushed without being squeezed under the restriction of magnetic repulsion.

[0010] Preferably, the air rod and air tube slide in a sealed manner, and the suction cup is made of rubber. The air rod, which slides in a sealed manner, can draw the gas inside the air tube and suction cup, and the suction cup made of rubber can fit tightly with the lens and avoid scratching the lens.

[0011] Preferably, the side of the clamping plate closest to the spring is made of rubber, and the bottom of the clamping plate is slidably disposed with respect to the top surface of the support plate. With the constraint of the rubber material, scratches on the outer wall of the lens can be avoided.

[0012] Preferably, there are six clamping plates, divided into three groups, which are equidistantly distributed on the top surface of the support plate. Under their constraint, multiple lenses can be clamped at the same time to improve lens processing efficiency.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The antistatic device used in this lens screen printing machine consists of a fixed assembly. When processing lenses, they need to be clamped. The lens is placed above the suction cup, and pressed to ensure a tight fit. Then, the limiting rod is pressed downwards to release the clamping block. Under the magnetic repulsion of the first and second magnetic blocks, the clamping block is pushed outwards from the slide groove, causing the side of the clamping block away from its inclined surface to contact and engage with the bottom of the tray. As the limiting rod moves downwards, it causes the pull plate and air spring to move downwards as well. Due to the sealed sliding of the air spring and air pipe, the limiting rod... The air rod draws air from the air pipe and the inside of the suction cup, allowing the suction cup to stably adsorb the lens, enabling stable lens processing and improving the static electricity removal and dust removal effects. After the lens is processed, the locking block is pressed to slide into the groove. At this time, the locking block is no longer locked to the bottom of the tray. Pushing the pull plate upward causes the air rod to push air into the air pipe and the inside of the suction cup, so that the suction cup no longer adsorbs the lens, and the lens can be removed. (The tray, linear motor, guide rail, static electricity removal and dust removal equipment are existing publicly disclosed technologies in the prior art, so their structures are not fully described in this case.)

[0015] 2. The antistatic device for the lens screen printing machine consists of an auxiliary component. When the lens needs to be processed, the two clamping plates are pushed in opposite directions and the lens is attracted by the fixing component. At this time, the clamping plates are released, and under the elastic action of the spring, the two clamping plates are pulled in opposite directions, so that the clamping plates slide on the outer wall of the slide rod and clamp the outer wall of the lens. This structure can assist in clamping the fixing component. Attached Figure Description

Detailed Implementation

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1: A preferred embodiment of the static eliminator for a lens screen printing machine provided by this utility model is as follows: Figures 1 to 6 As shown: An antistatic device for a lens screen printing machine, including a tray 1;

[0025] A linear motor 2 is fixedly installed at the bottom of the tray 1;

[0026] The bottom of the linear motor 2 is equipped with a sliding guide rail 3;

[0027] The processing component 4 is located above the guide rail 3. The processing component 4 includes a fixing component 41 located above the guide rail 3. The fixing component 41 includes an air pipe 411 fixedly installed inside the tray 1. A suction cup 412 is connected to the end of the air pipe 411. An air rod 413 is slidably installed inside the air pipe 411. A pull plate 414 is fixedly installed at the end of the air rod 413. A limit rod 415 is fixedly installed on the top surface of the pull plate 414. A sliding groove 416 is opened on the outer wall of the limit rod 415. A first magnetic block 417 is fixedly installed on the inner wall of the sliding groove 416. A second magnetic block 418 is slidably installed inside the sliding groove 416. A locking block 419 is fixedly installed on the side wall of the second magnetic block 418.

[0028] In this embodiment, when processing the lens, it needs to be clamped. The lens is placed above the suction cup 412, and pressed to ensure it fits tightly against the suction cup 412. Then, the limiting rod 415 is pressed downwards, relieving the clamping block 419 of pressure. Under the magnetic repulsion between the first magnetic block 417 and the second magnetic block 418, the clamping block 419 is pushed outwards towards the slide groove 416, causing the side of the clamping block 419 away from its inclined surface to contact and engage with the bottom of the support plate 1. When the limiting rod 415 moves downwards, it drives the pull plate 414 and the air rod 413 downwards. Because the air rod 413 and the air pipe 411 slide in a sealed manner, under its constraint, the air rod 413... The gas inside the tube 411 and suction cup 412 is drawn, so that the suction cup 412 stably adsorbs the lens, allowing the lens to be processed stably and improving the static electricity removal and dust removal effect. After the lens is processed, press the locking block 419 to slide it into the slide groove 416. At this time, the locking block 419 is no longer locked to the bottom of the support plate 1. Push the pull plate 414 upward, so that the air rod 413 pushes air into the air tube 411 and suction cup 412, so that the suction cup 412 no longer adsorbs the lens, and the lens can be removed. (The support plate 1, linear motor 2, guide rail 3, static electricity removal and dust removal equipment are existing public technologies in the prior art, so their structures are not fully described in this case.)

[0029] Furthermore, the first magnetic block 417 and the second magnetic block 418 are magnetically repulsive, and the outer wall of the second magnetic block 418 is slidably disposed inside the groove 416. Under the restriction of magnetic repulsion, the block 419, which is not squeezed, is pushed.

[0030] Furthermore, the air spring 413 and the air tube 411 slide in a sealed manner, and the suction cup 412 is made of rubber. The air spring 413, which slides in a sealed manner, can draw the gas inside the air tube 411 and the suction cup 412. The rubber suction cup 412 can fit tightly with the lens and avoid scratching the lens.

[0031] Example 2: Based on Example 1, a preferred embodiment of the static eliminator for a lens screen printing machine provided by this utility model is as follows: Figures 1 to 6 As shown: The auxiliary component 42 includes a fixed plate 421 fixedly installed on the top surface of the support plate 1. A slide rod 422 is fixedly installed on the outer wall of the fixed plate 421. A clamping plate 423 is slidably arranged on the outer wall of the slide rod 422. A spring 424 is fixedly installed on the side wall of the clamping plate 423.

[0032] In this embodiment, when the lens needs to be processed, the two clamping plates 423 are pushed in opposite directions and the lens is attracted by the fixing component 41. At this time, the clamping plates 423 are released, and under the elastic action of the spring 424, the two clamping plates 423 are pulled in opposite directions, so that the clamping plates 423 slide on the outer wall of the slide rod 422 to clamp the outer wall of the lens. This structure can assist the fixing component 41 in clamping.

[0033] Furthermore, the side of the clamping plate 423 closest to the spring 424 is made of rubber. The bottom of the clamping plate 423 is slidably set with the top surface of the support plate 1. With the constraint of the rubber material, the outer wall of the lens can be prevented from being scratched.

[0034] In addition, there are six clamping plates 423, which are divided into three groups and are evenly distributed on the top surface of the support plate 1. Under their constraint, multiple lenses can be clamped at the same time to improve the lens processing efficiency.

[0035] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
