Description

Technical Field

[0001] The invention relates to the field of UV exposure mold splicing, and in particular to automatic UV exposure mold splicing equipment. Background Art

[0002] UV exposure, or ultraviolet exposure technology, is a technology that uses ultraviolet light to irradiate photosensitive materials to cause chemical changes and thus achieve pattern transfer. The working principle of UV exposure mold assembly equipment is to use ultraviolet light to irradiate a substrate coated with photosensitive material, and selectively transmit ultraviolet light through the pattern on the mask template, so that the photosensitive material undergoes a chemical reaction under the irradiation of ultraviolet light, thereby forming the desired pattern on the substrate. After exposure, the unexposed part of the photosensitive material is removed through the development process, and finally the desired pattern is obtained.

[0003] With the development of science and technology, technicians in related fields have also made a lot of optimizations on UV exposure mold splicing equipment. In order to make a more accurate comparison, a Chinese patent with publication number CN216231141U discloses a splicing device on a UV splicing machine, including a glue dripping component, a pattern plate, a UV curing lamp, a pressure roller and a mounting frame, etc. When in use, the second cylinder drives the pressure roller downward to fit the pattern plate, and the first cylinder drives the mounting plate to move horizontally, so that the mounting plate drives the pressure roller and the UV curing lamp to slide on the pattern plate, and the UV glue on the pattern plate is spread, so that the UV is evenly laid at the pattern window, and the UV glue on the pattern plate is cured by irradiation with the UV curing lamp.

[0004] However, the above-mentioned imposition device still has some shortcomings in actual use:

[0005] 1. The UV curing lamp of the above device is installed on the mounting plate. When the mounting plate is driven to move horizontally by the first cylinder, the pressure roller and the UV curing lamp are driven to move horizontally at the same time, so that after the pressure roller applies UV glue on the pattern plate, the UV glue is irradiated by the UV curing lamp to cure it. However, during the irradiation of the UV curing lamp, the first cylinder always drives the mounting plate to move horizontally, so that the UV curing lamp stays on the same area to irradiate the UV glue for a very short time, and the UV curing lamp needs to irradiate the UV glue for a period of time before the UV glue can be cured thoroughly and evenly. The UV glue that is not completely cured will continue to adhere to the pattern plate, affecting the subsequent staff to remove it, thereby reducing the practicality of the above device when used.

[0006] 2. When the above device is in use, the pattern plate to be used is clamped and limited between the first mounting plate and the second mounting plate which are hinged together at one end, and then fixed and locked together by a buckle. And during subsequent use, the pattern on the pattern plate is exposed through the second mounting opening of the second mounting plate, while the remaining sides of the pattern plate are blocked and limited by the first mounting plate and the second mounting plate. When the pattern size of the exposure die assembly to be exposed is relatively large, after the pattern plate is limited by the first mounting plate and the second mounting plate, it is inconvenient to show all the patterns on the pattern plate. Moreover, after the pattern plate is buckled by the first mounting plate and the second mounting plate, there is still a step height between the pattern plate and the first mounting plate and the second mounting plate. Due to the depth of the texture structure itself and the fit problem of the engraving CNC inlay, there will be an uncontrollable step height at the inlay edge, which has a great impact on the later yield rate.

[0007] Therefore, under the above-stated viewpoints, there is still room for improvement in the existing UV exposure die assembly equipment. Summary of the Invention

[0008] In order to solve the above problems, the present invention provides an automatic UV exposure die assembly equipment, which includes a working frame arranged in a U-shaped opening. An exposure lamp is arranged downward on the working frame. Between the two horizontal sections of the working frame, an exposure platform is jointly arranged below the exposure lamp. The exposure platform is used for placing the processing template, and a downward-extending support tube is arranged at its lower end. A limiting member for limiting and installing the processing template is arranged on the exposure platform.

[0009] The limiting member includes a limiting frame arranged on the working frame above the exposure platform. The limiting frame is arranged in a bent structure and has a through opening corresponding to the exposure platform in the middle, which is used for initially restricting the position of the workpiece of the processing template. A clamping end for limiting the processing template is connected to the limiting frame. A driving end for driving the clamping end to limit and clamp the workpiece is also arranged on the lower horizontal section of the working frame.

[0010] Preferably, the clamping end includes a plurality of sliding clamping blocks symmetrically distributed circumferentially around the support tube on the upper side of the limiting frame. One end of the sliding clamping block close to the middle support tube is connected with a limiting clamping block for pushing the processing template to shift.

[0011] Preferably, the driving end includes a mounting frame plate sleeved on a plurality of sliding clamping blocks together. A sliding groove corresponding to the sliding clamping block is opened on the mounting frame plate to limit the sliding path of the sliding clamping block. An annular gear disk is connected to the upper end of the mounting frame plate. A spiral slide bar for driving the sliding clamping block to slide is jointly connected between the annular gear disk and the mounting frame plate. The spiral slide bar slides through the sliding clamping block. A plurality of limiting guide rods connected to the working frame are arranged circumferentially at the lower end of the mounting frame plate.

[0012] Preferably, the driving end further comprises a rotating wheel rod inserted on the working frame, and the rotating wheel rod is sleeved with a driving gear disc meshing with the annular gear disc.

[0013] Preferably, at least two guide blocks are symmetrically connected to the limit frame, and the lower ends of the two guide blocks are commonly connected to an arc-shaped sleeve. The interior of the arc-shaped sleeve is hollow and a plurality of discharge ports for discharging materials are evenly arranged in the circumferential direction of the lower side. The middle part of the upper side of the arc-shaped sleeve is connected to a storage bin for storing UV glue, and a glue roller is attached to the arc surface of the lower side of the arc-shaped sleeve.

[0014] Preferably, connecting rods are symmetrically arranged at both ends of the rubber roller, and a passive gear is sleeved on the connecting rods. A plurality of gear grooves matching the passive gear are evenly arranged on the working frame.

[0015] Preferably, a driving rotating rod is provided between the storage bin and the guide block, and the driving rotating rod is symmetrically connected to stirring blades located in the storage bin.

[0016] Preferably, at least two arc-shaped push blocks are symmetrically connected inside the arc-shaped sleeve, and the arc-shaped push blocks are connected with a bidirectional screw rod passing through the arc-shaped sleeve.

[0017] Preferably, a driven rotating block is connected to the inner wall of the lower side of the supporting tube, and an adjusting screw is provided through the driven rotating block and the middle part of the supporting tube.

[0018] Preferably, the outer side surface of the supporting tube is symmetrically connected to the limiting sliding strip.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. The present invention arranges the cut sheet templates on the exposure platform, and then uses limiting parts to position and limit the four sides of the sheet on which the pattern needs to be copied on the surface and the texture template after the mold is assembled. After UV glue is evenly applied between the sheet and the texture template, the exposure lamp on the working frame is used to irradiate the UV glue on the texture template after the mold is assembled so that the UV exposure time is the same, thereby completely curing the UV glue and improving the finished product yield of the sheet replication.

[0021] 2. The present invention drives the rubber roller to rotate while driving the rubber roller to slide horizontally, and also drives the two arc-shaped push blocks in the arc-shaped sleeve on the upper side of the rubber roller to adjust the area storing UV glue in the arc-shaped sleeve according to the size of the processing template after the mold is assembled, so that the UV area in the arc-shaped sleeve that falls and contacts the rubber roller corresponds to the size of the processing template, thereby improving the efficiency of UV glue application and saving costs.

[0022] 3. The present invention drives a plurality of circumferentially distributed sliding clamps on the outside of the supporting tube to slide in a direction close to the supporting tube. The movement of the sliding clamps drives the connected limiting clamps to slide synchronously. After the limiting clamps come into contact with the processing template and the sheet to be processed, the limiting clamps push the processing template and the sheet to be processed to adjust their positions in a direction close to the middle of the supporting tube, thereby achieving the effect of self-positioning limiting clamping of the processing template and the sheet to be processed.

Specific embodiments

[0039] The following will Figure 1 be combined with the attached Fig.14 drawings to describe the embodiments of the present invention in detail. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0040] The embodiment of the present application discloses an automatic UV exposure die - assembling device. It should be noted that this automatic UV exposure die - assembling device is mainly applied in the process of exposing and die - assembling sheet materials, and achieves the effect of copying the texture of the processing template to the sheet material by exposure; especially when die - assembling the texture template, the texture template is directly placed on the exposure platform to avoid the formation of a step height between the edge of the processing template and the exposure platform during processing; further, this automatic UV exposure die - assembling device also adjusts the area where the UV glue is applied on the rubber roller according to the size of the processing template, effectively saving the processing cost.

[0041] Embodiment 1: Refer to Figure 1 and Figure 2 As shown, an automatic UV exposure die - assembling device includes a working frame 1, an exposure lamp 10, an exposure platform 11, a supporting tube 12, and a limiting member 2. The working frame 1 is arranged in a U - shaped opening. An exposure lamp 10 is arranged downward on the working frame 1. An exposure platform 11 is jointly arranged between the two horizontal sections of the working frame 1 and is located below the exposure lamp 10. The exposure platform 11 is used for placing the processing template, and a supporting tube 12 extending downward is arranged at its lower end. A limiting member 2 for limiting and installing the sheet material to be processed is arranged on the exposure platform 11.

[0042] When in use, the cut PET sheet with texture (that is, the processing template) is placed on the exposure platform 11 to arrange several array patterns to be spliced ​​into a processing template of the required size, and then the sheet to be processed is covered on all the templates, and the position of the processing template and the sheet to be processed is positioned and adjusted by the limiter 2, so that the position of the sheet and the processing template corresponds to the position of the processing template. After completing the limiting and positioning of the sheet and the processing template, UV glue is evenly applied between the material and the processing template, so that the UV glue covers all the texture areas on the processing template, and then the film is covered on the sheet to be processed to block the position on the sheet where the texture does not need to be copied, and the required pattern texture is leaked, so that the film, the sheet to be processed and the processing template are stacked together in order from top to bottom, and finally the exposure lamp 10 is irradiated on the film, the sheet to be processed and the processing template to solidify the UV glue applied therein, and the second layer of the sheet is taken out for cleaning to obtain the required texture template, and the pattern therein is copied.

[0043] It should be noted that the PET sheet is used as the material for the processing template in the present invention, mainly because the PET material has the following advantages over the PC material:

[0044] 1. UV transmittance: PET material has a higher transmittance to ultraviolet rays, which makes it perform better in situations where UV light penetration is required (such as UV curing). Although PC material also has a certain UV transmittance, it usually absorbs and scatters more UV light than PET.

[0045] 2. Chemical resistance: PET material has good tolerance to many chemicals, including some solvents and acids and bases, which makes it more stable than PC when handling certain chemicals.

[0046] 3. Cost-effectiveness: PET material is generally cheaper than PC material, which makes it more cost-effective when applied.

[0047] 4. Processability: PET material has good processability and is easy to shape and process, which is very useful when rapid prototyping or small batch production is required.

[0048] 5. Environmental protection: PET materials can be recycled, while PC materials are relatively difficult to recycle. Therefore, in terms of environmental protection, PET materials have certain advantages.

[0049] Reference Figures 2 to 3As shown, the limit member 2 is used for limiting the installation of the processing template; specifically, the limit member 2 includes a limit frame 20, a clamping end 21 and a driving end 22. The working frame 1 is provided with a limit frame 20 located on the upper side of the exposure platform 11. The limit frame 20 is arranged in a bent structure and a through opening is arranged in the middle corresponding to the exposure platform 11, which is used for preliminarily limiting the position of the workpiece of the processing template. The limit frame 20 is connected with a clamping end 21 for limiting the processing template, and the horizontal section on the lower side of the working frame 1 is also provided with a driving end 22 for driving the clamping end 21 to limit and clamp the workpiece.

[0050] When in use, after the processing template and the sheet to be processed are placed on the exposure platform 11 accordingly, the driving end 22 drives the clamping end 21 to slide and shift on the upper side of the limiting frame 20. During the sliding process, the clamping end 21 gradually pushes the processing template and the sheet to be processed on the exposure platform 11 to slide and shift to a position close to the middle of the supporting tube 12, thereby achieving the effect of driving the clamping end 21 to limit and position the processing template and the sheet, thereby facilitating the subsequent further processing of the sheet and the processing template.

[0051] Reference Figures 3 to 5 As shown, the clamping end 21 is used to limit the processing template; specifically, the clamping end 21 includes a sliding clamp block 210 and a limiting clamp block 211, and a plurality of sliding clamp blocks 210 are arranged on the upper side of the limiting frame 20, which are symmetrically distributed around the supporting tube 12 as the central axis, and the end of the sliding clamp block 210 close to the middle supporting tube 12 is connected to the limiting clamp block 211 for pushing the processing template to shift.

[0052] When in use, the driving end 22 drives several circumferentially distributed sliding clamps 210 on the outside of the supporting tube 12 to slide in the direction close to the supporting tube 12, and the movement of the sliding clamps 210 drives the connected limit clamps 211 to slide synchronously. After the limit clamps 211 come into contact with the processing template and the sheet to be processed, the limit clamps 211 push the processing template and the sheet to be processed to adjust their positions in the direction close to the middle of the supporting tube 12, thereby achieving the effect of self-positioning, adjusting and clamping the processing template and the sheet to be processed.

[0053] Reference Figures 3 to 5As shown, the driving end 22 is used to drive the clamping end 21 to limit the clamping of the workpiece; specifically, the driving end 22 includes a mounting frame plate 220, a sliding groove 221, an annular gear plate 222 and a spiral slide bar 223. The mounting frame plate 220 is commonly sleeved on a plurality of sliding clamps 210. The mounting frame plate 220 is provided with a sliding groove 221 corresponding to the sliding clamp 210 to limit the sliding path of the sliding clamp 210. The upper end of the mounting frame plate 220 is rotatably connected with an annular gear plate 222. A spiral slide bar 223 for driving the sliding clamp 210 to slide is commonly connected between the annular gear plate 222 and the mounting frame plate 220. The spiral slide bar 223 is slidably penetrated on the sliding clamp 210. The lower end of the mounting frame plate 220 is circumferentially provided with a plurality of limiting guide rods connected to the working frame 1.

[0054] When in use, by driving the annular toothed disk 222 to rotate, the annular toothed disk 222 drives the spiral slide bar 223 to rotate. After the spiral slide bar 223 rotates, the sliding clamp 210 slides along the outer side surface of the spiral slide bar 223, and the sliding clamp 210 slides in the sliding groove 221 on the mounting frame plate 220 at the same time. Since the mounting frame plate 220 is rotationally connected to the annular toothed disk 222, and the lower end of the mounting frame plate 220 is limitedly installed on the working frame 1 by a limiting guide rod, the rotation of the annular toothed disk 222 will not drive the mounting frame plate 220 to rotate.

[0055] Based on the above, when the annular toothed disk 222 is driven to rotate forward, the sliding clamp block 210 slides along the sliding groove 221 through the spiral slide bar 223 toward the direction close to the middle supporting tube 12, and drives the connected limit clamp block 211 to self-position and clamp the processing template and the sheet to be processed. When the annular toothed disk 222 is driven to rotate reversely, the sliding clamp block 210 slides along the sliding groove 221 through the spiral slide bar 223 toward the direction away from the supporting tube 12, thereby releasing the clamping of the processing template and the sheet to be processed.

[0056] Reference Figures 3 to 5 As shown, the driving end 22 also includes a rotating wheel rod 224 inserted on the working frame 1, the lower end of the rotating wheel rod 224 is connected to a rotating motor installed on the working frame 1, and a driving sprocket 225 meshing with the annular sprocket 222 is sleeved on the rotating wheel rod 224. When in use, the rotating wheel rod 224 is driven to rotate by the output shaft of the rotating motor, and the rotating wheel rod 224 rotates to drive the driving sprocket 225 to rotate, and the driving sprocket 225 rotates to drive the meshing annular sprocket 222 to rotate, thereby driving the limiting clamp 211 to position, clamp and release the processing template and the sheet to be processed on the exposure platform 11.

[0057] Refer to 6 to Fig. 9As shown, at least two guide blocks 23 are symmetrically inserted on the limit frame 20, and limit grooves corresponding to the two guide blocks 23 are symmetrically formed on the limit frame 20 to allow the guide blocks 23 to slide and shift. The lower ends of the two guide blocks 23 are commonly connected to an arc sleeve 24, the arc sleeve 24 is hollow inside and a plurality of discharge ports 240 for discharging are evenly opened on the lower side in a circumferential direction. The middle part of the upper side of the arc sleeve 24 is connected to a storage bin 25 for storing UV glue, and a glue roller 26 is attached to the arc surface of the lower side of the arc sleeve 24.

[0058] When in use, the UV glue placed in the storage bin 25 is allowed to enter the arc sleeve 24, and then drips onto the surface of the rubber roller 26 through the discharge port 240 on the arc sleeve 24, and then the rubber roller 26 is driven to shift on the processing template, so that the UV glue attached to the rubber roller 26 is evenly spread on the processing template, and then the sheet to be processed is driven to fit onto the processing template accordingly, and then the UV glue between the processing template and the sheet is cured by the irradiation of the exposure lamp 10, thereby completing the effect of copying the texture pattern on the processing template to the sheet to be processed.

[0059] Reference Figures 6 to 9 As shown, connecting rods 260 are symmetrically arranged at both ends of the rubber roller 26, and a passive gear 261 is also sleeved on the connecting rod 260. A plurality of gear grooves 262 that match the passive gear 261 are evenly opened on the working frame 1. When in use, after the film, the sheet to be processed and the processing template are positioned, the supporting tube 12 and the exposure platform 11 are driven to move downward, and the exposure platform 11 moves downward to drive all the processing templates placed thereon to move downward to the lower side of the rubber roller 26, and then the connecting rod 260, the rubber roller 26 and the passive gear 261 are driven to slide in a direction away from the driving gear disc 225. During the sliding process, the passive gear 261 is driven to rotate by the gear grooves 262 evenly arranged on the working frame 1, and the rotation of the passive gear 261 drives the connecting rod 260 and the rubber roller 26 to rotate, so that the rubber roller 26 evenly coats the UV glue falling from the arc sleeve 24 on the arc surface of the rubber roller 26.

[0060] After the rubber roller 26 slides to the position of the processing template and contacts it, as the rubber roller 26 slides and rotates, the UV glue attached to the rubber roller 26 is coated on the processing template, achieving the effect of evenly coating the UV glue on the processing template. After the coating is completed, the supporting tube 12, the exposure platform 11 and all the processing templates are driven to move up and contact the sheet to be processed again, so that the sheet and all the processing templates are adhered together.

[0061] It should be noted that in order to drive the rubber roller 26 to slide and rotate between the limiting frame 20 and the working frame 1, a driving motor 263 is connected to either end of the connecting rod 260, and the driving motor 263 is slidably mounted on the working frame 1 through a motor seat.

[0062] When in use, after the connecting rotating rod 260 is driven to rotate by the driving motor 263, the connecting rotating rod 260 rotates and drives the passive gears 261 at both ends thereof to rotate. After the passive gear 261 rotates, it rotates and slides along the several gear grooves 262 arranged on the working frame 1 in sequence, so as to achieve the effect of making the rubber roller 26 slide and rotate at the same time. At the same time, the rotation and sliding of the passive gear 261 also drives the driving motor 263 to rotate and slide, and the driving motor 263 is limited by the motor seat and is only allowed to slide on the working frame 1, thereby achieving the effect of evenly applying the UV glue on the processing template.

[0063] Reference Fig. 9 and Fig.10 As shown, a driving rotating rod 250 is provided between the storage bin 25 and the guide block 23, and the driving rotating rod 250 is symmetrically connected with stirring blades 251 located in the storage bin 25. The two stirring blades 251 are arranged in a spiral structure and fit with the inner wall of the storage bin 25, and the two ends of the driving rotating rod 250 are symmetrically sleeved with rotating gears 252 meshing with the passive gear 261.

[0064] When in use, after driving the rotating wheel rod 224 and the passive gear 261 to rotate, the passive gear 261 drives the rotating gear 252 meshing therewith to rotate, and the rotating gear 252 drives the driving rotating rod 250 and the stirring blade 251 to rotate, thereby driving the stirring blade 251 to stir the UV glue in the storage bin 25 to maintain the fluidity of the UV glue.

[0065] Furthermore, since the two stirring blades 251 are arranged in a spiral structure and are symmetrically distributed, after the two stirring blades 251 are driven to rotate in the storage bin 25, the UV glue in the storage bin 25 is stirred and gathered toward the middle along the blades of the stirring blades 251, thereby driving the UV glue in the storage bin 25 to always be discharged downward from the middle into the arc sleeve 24.

[0066] Reference Figures 9 to 11As shown, at least two arc-shaped push blocks 241 are symmetrically connected in the arc sleeve 24, and a bidirectional screw rod 242 passing through the arc sleeve 24 is connected to the arc push block 241. The bidirectional screw rod 242 is provided with two threads in opposite directions, and the two arc push blocks 241 are respectively located on two opposite threaded sections, and the bidirectional screw rod 242 and the connecting rotating rod 260 are connected by a belt transmission. Specifically, a synchronous pulley is sleeved on the outer side of a section of the bidirectional screw rod 242 passing through the arc sleeve 24, and a synchronous pulley is also sleeved on the connecting rotating rod 260. The two synchronous pulleys are connected by a synchronous belt transmission. After the connecting rotating rod 260 drives one of the connected synchronous pulleys to rotate, the synchronous pulley drives the other synchronous pulley and the bidirectional screw rod 242 to rotate through the connected synchronous belt, thereby realizing the synchronous rotation effect of the connecting rotating rod 260 and the bidirectional screw rod 242.

[0067] During specific use, after driving the bidirectional screw rod 242 to rotate, the two arc-shaped push blocks 241 on the bidirectional screw rod 242 move toward or away from each other through the thread of the bidirectional screw rod 242, thereby adjusting the discharge position of the UV glue in the arc-shaped sleeve 24, thereby adjusting the area of ​​the UV glue attached to the glue roller 26 according to the size after the processing template is arranged, avoiding waste and achieving the effect of saving costs.

[0068] Reference Fig.12 and Fig.13 As shown, a driven rotating block 27 is connected to the inner wall of the lower side of the bearing tube 12, and an adjusting screw 270 is commonly penetrated through the driven rotating block 27 and the middle part of the bearing tube 12. The adjusting screw 270 is threadedly inserted into the bearing tube 12 after passing through the driven rotating block 27. The adjusting screw 270 and the rotating wheel rod 224 are connected by a belt drive, and the lower end of the adjusting screw 270 is connected to an adjusting motor installed on the working frame 1.

[0069] When in use, after the adjusting screw 270 is driven to rotate by the adjusting motor, the driven rotating block 27 is driven to slide up and down along the axial direction of the adjusting screw 270 through the threaded cooperation between the adjusting screw 270 and the driven rotating block 27. When the adjusting screw 270 is driven to rotate in the forward direction, the driven rotating block 27 slides upward along the adjusting screw 270 through the thread, and the driven rotating block 27 moves upward to drive the supporting tube 12 and the exposure platform 11 to move upward; when the adjusting screw 270 is driven to rotate in the reverse direction, the driven rotation drives the supporting tube 12 and the exposure platform 11 to move downward along the adjusting screw 270, thereby achieving the effect of adjusting the vertical position of the supporting tube 12 and the exposure platform 11.

[0070] Further, refer to Fig.12 and Fig.13As shown, when the driven rotating block 27 is driven to rotate by the adjusting screw 270, the rotation of the driven rotating block 27 will also drive the supporting tube 12 to rotate accordingly. In order to prevent the rotation of the supporting tube 12 from driving the exposure platform 11 to rotate, thereby causing the relative position between the processing module and the sheet to be processed to be shifted, resulting in the problem of misprinting the pattern during subsequent exposure, the supporting tube 12 and the driven rotating block 27 are arranged to be rotatably connected, and a limiting slide bar 271 slidably inserted on the working frame 1 is symmetrically connected to the outer side surface of the supporting tube 12 to prevent the supporting tube 12 from being driven to rotate and allow up and down sliding adjustment in the vertical direction.

[0071] When in use, by driving the adjusting screw 270 to rotate in the forward direction, the driven rotating block 27 moves up along the axial direction of the adjusting screw 270 through the thread, and the driven rotating block 27 moves up to drive the supporting tube 12, the limiting slide 271 and the exposure platform 11 to move up. When the adjusting screw 270 is driven to rotate in the reverse direction, the driven rotating block 27 moves down along the adjusting screw 270 through the thread, and at the same time drives the supporting tube 12, the limiting slide 271 and the exposure platform 11 to move down, thereby achieving the effect of adjusting the vertical position of the supporting tube 12 and the exposure platform 11.

[0072] Example 2: Reference Fig.14 As shown, on the basis of Example 1, when the sliding clamp 210 and the limiting clamp 211 are driven by the annular gear plate 222 and the spiral slider 223 to limit the arranged processing template, the rotation of the spiral slider 223 will simultaneously drive all the sliding clamps 210 and the limiting clamps 211 to slide and press against the processing template to limit the position, and the complete shape of multiple PET sheets after arrangement and splicing is not necessarily a regular polygon, which will result in not all the sliding clamps 210 and the limiting clamps 211 being able to contact the spliced ​​processing template after moving.

[0073] Based on this, an extension piece 3 is provided on the sliding clamp 210 and the limiting clamp 211. Specifically, the extension piece 3 includes an extension bar 30, a rotating pin 31, a limiting slider 32 and an adjusting spring 33. A cavity is formed on the sliding clamp 210 on one side close to the connected limiting clamp 211. An extension bar 30 connected to the limiting clamp 211 is slidably inserted in the cavity. The extension bar 30 and the limiting clamp 211 are rotatably connected by the rotating pin 31. The extension bar 30 is sleeved with a limiting slider 32 located in the cavity. The extension bar 30 is also sleeved with an adjusting spring 33 located between the inner wall of the cavity and the limiting slider 32.

[0074] When in use, by rotating the annular toothed disc 222 and the spiral slide bar 223 to drive all the sliding clamps 210 and the limiting clamps 211 to slide and shift in the direction close to the middle supporting tube 12, the sliding clamp 210 moves and drives the connected extension bar 30, the limiting slider 32, the adjusting spring 33 and the limiting clamp 211 to slide. After the limiting clamp 211 first contacts the processing template, the limiting clamp 211 is restrained by all the processing templates, and as the sliding clamp 210 continues to slide close, the limiting clamp 211 is driven to deflect at an angle with the rotating pin 31 as the axis, and at the same time moves away from the processing template. The connected extension bar 30 and the limit slider 32 are pushed to slide in the direction away from the processing template. After the limit slider 32 is moved, the connected adjustment spring 33 is compressed, and the adjustment spring 33 is compressed and needs to be restored to a normal extended state, thereby applying force to the connected extension bar 30 and the limit slider 32 to slide in the direction close to the processing template, so that the limit clamp 211 is pressed against the outer side of the processing template. By pressing a plurality of limit clamps 211 symmetrically distributed around the outer side of the processing template against the outer side of the processing template, the effect of adaptively pressing the processing template is achieved.

[0075] When working: the first step is material preparation; use a laser engraving machine to cut out several sheets of the same texture on the PET material, put the cut PET sheets with texture on the exposure platform 11 to arrange several array patterns, and combine and splice them into a processing template of the required size.

[0076] Step 2: Sheet positioning; cover the film and the sheet to be processed on the processing template accordingly, so that the film, the sheet to be processed and the processing template are stacked together in order, and then drive the sliding clamp 210 and the limiting clamp 211 to limit and position the film, the sheet to be processed and the processing template. After positioning is completed, drive the exposure platform 11 and the processing template on the exposure platform 11 to move down to be flush with the working frame 1, and use the moving glue roller 26 to evenly apply UV glue to all textured areas on the processing template.

[0077] Step 3: UV curing; after the UV glue is applied to the texture area on the processing template, the exposure platform 11 and the processing template coated with UV glue are driven up again, so that the sheet to be processed is attached to the processing template, and the exposure lamp 10 is enabled to irradiate the film, the sheet to be processed and the processing template to cure the UV glue between the processing template and the sheet to be processed. After a period of time, the second layer of sheet is removed and cleaned, and the desired texture template can be obtained, completing the replication effect of the pattern on the template.
