Description

Technical Field

[0001] This invention relates to the field of home appliance manufacturing technology, and in particular to a laser screen bonding machine. Background Technology

[0002] A laser TV is a projection display device that uses a laser light source as the display light source and combines it with front projection display technology to create an image. It is equipped with a dedicated projection screen and can receive broadcast television programs or internet television programs. A projection screen is a tool used to display images and video files. Projection screens are widely used in cinemas, offices, home theaters, large conferences, and other settings.

[0003] Most laser TVs on the market are short-throw laser projectors, offering advantages such as easy installation and space-saving design. Due to their short-throw characteristics, the choice of screen for laser TVs differs significantly from that of ordinary projection screens. Laser TVs require an ambient light rejecting screen to maximize their display advantages.

[0004] In related technologies, laser screens use Fresnel lens films bonded to tensile-resistant synthetic fabric, supported by an aluminum alloy frame to enhance the projection effect of laser TVs. Traditionally, laser screen production is done manually. Operators place the synthetic fabric on an aluminum plate table, holding it flat with springs around its edges. The operator aligns the front and left edges of the film with the front and left edges of the synthetic fabric. Then, pressure rollers are used to press the fabric, starting from the front edge and continuing to the rear edge. The disadvantages of this production method are that manual alignment of the film and fabric results in low precision and potential misalignment; different screen sizes require different workbenches, making workbench changes time-consuming and labor-intensive during production transitions.

[0056] In related technologies, laser screens use Fresnel films bonded to tensile-resistant synthetic fabric, supported by an aluminum alloy frame, to enhance the projection effect of laser TVs. Traditionally, laser screen production relies on manual labor. An operator places the synthetic fabric on an aluminum plate table, using springs to flatten it around the edges. The operator aligns the front and left edges of the film with the front and left edges of the synthetic fabric. Then, pressure rollers are used to press the fabric, starting from the front edge and continuing to the rear edge. The disadvantages of this production method are that manual alignment of the film and fabric results in low precision and potential misalignment; different screen sizes require different tables, making table changes time-consuming and labor-intensive during production transitions. This application provides a laser screen bonding machine to solve the above-mentioned technical problems.

[0057] Figure 1 This is a structural schematic diagram of the invention bonding machine. Figure 2 This is a schematic diagram of the structure of the screen of the present invention.

[0058] For ease of description and understanding, the working state of the laminating machine is used as a reference. The moving direction of the pressure roller mechanism is longitudinal, the horizontal direction perpendicular to the longitudinal direction is transverse, and the vertical direction is up and down.

[0059] See Figure 1 and Figure 2 This application provides a laminating machine for a laser screen. The laser screen includes a screen 90 and a diaphragm (not shown). Frame strips 91 are fixed to the four edges of the screen 90. The radial diameter of the frame strips 91 is greater than the thickness of the screen 90. The laminating machine is used to laminate the diaphragm onto the screen 90. In this embodiment, the frame strips 91 are strip-shaped structures made of aluminum alloy.

[0060] In this application, the laminating machine includes a frame 10, a curtain fixing mechanism 20 disposed on the frame 10, a film placement mechanism 30 disposed on the frame 10, and a pressure roller mechanism 40 disposed on the frame 10. The curtain fixing mechanism 20 is used to place and fix the curtain 90, the film placement mechanism 30 is used to place and position the film, and the pressure roller mechanism 40 is used to adsorb the film on the film placement mechanism 30 and place it on the upper surface of the curtain 90 on the curtain fixing mechanism 20. The pressure roller mechanism 40 can also press the upper surface of the film on the curtain 90 so that the film is adhered to the curtain 90. An adhesive is provided on the curtain 90 or the film for bonding the curtain 90 and the film, so that after the pressure roller mechanism 40 moves the film onto the curtain 90, the film can be adhered to the curtain 90 by pressing the film.

[0061] Figure 3 This is a schematic diagram of the frame structure of the present invention. Figure 4 yes Figure 3 Enlarged view of point A in the middle.

[0062] See Figures 1 to 4 The frame is a fixed frame structure made of square steel or aluminum alloy. The frame includes two longitudinal bars spaced laterally and multiple transverse bars positioned between the two longitudinal bars. The two longitudinal bars extend longitudinally, and the multiple transverse bars extend laterally. The multiple transverse bars are spaced longitudinally, with each end fixed to a longitudinal bar. Vertical bars are fixed to the transverse or longitudinal bars, with their upper ends fixedly connected to the transverse or vertical bars. Multiple leveling blocks 11 are located at the bottom of the frame. These leveling blocks 11 can move and be limited vertically relative to the frame to ensure the frame is stably placed on the ground and that its upper end is level. The combined action of the multiple leveling blocks 11 also allows for adjusting the height of the frame. The leveling blocks 11 are located at the bottom of the vertical bars.

[0063] In this embodiment, the leveling pad 11 is threaded to the bottom end of the frame so that the height position of the bottom end of the leveling pad 11 can be adjusted by rotating the leveling pad 11. In some embodiments, the leveling pad 11 is vertically slidable and limited on the frame.

[0064] In this embodiment, the upper end of the frame is provided with a longitudinally extending movable rack 12 and a longitudinally extending movable slide rail 13. The film placement mechanism 30 and the pressure roller mechanism 40 are slidably mounted on the movable slide rail 13, allowing them to move longitudinally relative to the frame. The film placement mechanism 30 and the pressure roller mechanism 40 are each provided with gears for meshing with the movable rack 12, used to control their movement on the frame. Both the movable rack 12 and the movable slide rail 13 are fixed to the upper surface of the longitudinal rod, and two of each are provided. The two movable racks 12 are spaced laterally apart, and the two movable slide rails 13 are spaced laterally apart. Each longitudinal rod is provided with one movable rack 12 and one movable slide rail 13.

Figure 6 This is a schematic diagram of the connection of the hook and the hook drive assembly of the present invention. Figure 7 This is a schematic diagram of the hook structure of the present invention. Figure 8 This is a schematic diagram of the hook drive assembly of the present invention.

[0066] See Figures 1 to 8A screen fixing mechanism 20 is fixed to the frame 10 for fixing the screen 90. The screen fixing mechanism 20 includes a screen placement platform 210 fixed to the frame 10 for placing the screen 90, multiple hooks 220 disposed on the screen placement platform 210, and multiple hook driving assemblies 230. The screen 90 is placed on the screen placement platform 210, and the multiple hooks 220 are disposed around the screen placement platform 210 and located on the upper surface of the screen placement platform 210. The hooks 220 are used to hook the frame strips 91 around the screen 90, and the hook driving assemblies 230 are used to drive the hooks 220 to translate, so as to tighten the screen 90. Through the hooking and translation of the hooks 220, the hooks 220 can tighten screens of different sizes. The hooks 220 and hook driving assemblies 230 are set in four groups to correspond to the four frame strips 91 of the four edges of the screen 90. The two hooks are set with a horizontal spacing of 220 and a vertical spacing of 220.

[0067] The upper surface of the screen placement platform 210 is horizontal, and the lower surface of the hook 220 has a recessed groove 221 for engaging with the corresponding frame strip 91. When the hook 220 moves downward, the groove 221 engages with the frame strip 91, and the lower end of the frame strip 91 abuts against the screen placement platform 210, thereby limiting the frame strip 91 within the groove 221.

[0068] The hook drive assembly 230 includes a first fixed plate 231, a pull plate 232 slidably disposed on the first fixed plate 231, a first lead screw 233 passing through the pull plate 232, and a hook drive unit 234 for driving the first lead screw 233 to rotate. The first fixed plate 231 is fixed to the curtain placement platform 210 or the frame. The first lead screw 233 is threadedly connected to the pull plate 232 so that when the first lead screw 233 rotates, it drives the pull plate 232 to slide. The hook 220 is connected to the pull plate 232. The hook drive unit 234 is a drive motor, which is driven by the first lead screw 233 to drive the first lead screw 233 to rotate.

[0069] It should be noted that in this application, the transmission connection is a gear connection, pulley connection, or belt connection, etc. A sliding connection is generally a connection between a slider and a slide rail, or a sliding connection within a groove. Connections not explicitly described in the text can be considered as connections between a slider and a slide rail. The rotation of the lead screw or corresponding shaft structure can be considered as having a bearing seat on the corresponding structure, with the lead screw and the corresponding structure passing through and rotating on the bearing seat. When the corresponding structure and the lead screw are threadedly connected, it can be considered as having a threaded sleeve or nut on the corresponding structure, so that the threaded sleeve or nut fits around the outer circumference of the corresponding lead screw.

[0070] A first slide rail 235 and a first slider 236 are provided between the pull plate 232 and the first fixed plate 231; the first slide rail 235 is fixed on the first fixed plate 231 and extends in a straight line; the first slider 236 is fixedly connected to the pull plate 232 and is slidably disposed on the first slide rail 235 along the extension direction of the first slide rail 235.

[0071] It should be noted that a first telescopic cylinder 240 is also provided between the hook 220 and the hook drive assembly 230 to drive the hook 220 to move vertically. One end of the hook 220 is located above the curtain placement platform 210, and the other end of the hook 220 is fixed to the first telescopic cylinder 240. The upper surface of the curtain placement platform 210 is horizontal, and the lower surface of the hook 220 has a recessed groove 221 for engaging with the corresponding frame strip 91. The first telescopic cylinder 240 drives the hook 220 to move vertically, thereby causing the hook 220 to be detachably engaged with the frame strip 91. The detachable engagement of the hook 220 with the frame strip 91 allows the curtain 90 to be confined between multiple hooks 220 and can be removed from the hooks 220.

[0072] The hook drive assembly 230 is located on the periphery of the screen placement platform 210. One end of the hook 220, which is connected to the first telescopic cylinder 240, extends out of the screen placement platform 210. The end of the hook 220 with the pull groove 221 is suspended, which makes the hook 220 elastic. This elasticity can maintain the hook 220 towards the screen placement platform 210, so as to ensure the reliability and stability of the frame strip 91.

Figure 10 This is a structural schematic diagram of the pressure roller mechanism of the present invention from another perspective. Figure 11 This is a schematic diagram of the structure of the mobile frame of the present invention.

[0074] See Figures 9 to 11 and combined Figure 1 The pressure roller mechanism 40 includes a movable frame 410, an adsorption assembly 420 disposed on the movable frame 410, and a pressure roller assembly 430 disposed on the movable frame 410. The movable frame 410 is slidably disposed on the frame in the longitudinal direction to drive the adsorption assembly 420 and the pressure roller assembly 430 to slide. The adsorption assembly 420 is used to adsorb the film on the film placement mechanism 30 to drive the film to be placed on the upper surface of the screen 90 on the screen placement platform 210. The pressure roller assembly 430 is configured to move with the movable frame 410 to roll on the upper surface of the film to drive the film to be adhered to the screen 90.

[0075] In this embodiment, the upper end of the frame is provided with a longitudinally extending movable rack and a longitudinally extending movable slide rail; the movable frame 410 is provided with a displacement slider 411, a displacement gear 412, and a displacement drive unit 413; the displacement slider 411 is fixed to the bottom end of the movable frame 410 and is slidably mounted on the movable slide rail in the longitudinal direction; the displacement gear 412 is rotatably connected to the movable frame 410 and meshes with the movable rack; the displacement drive unit 413 is driven by the displacement gear 412 to drive the displacement gear 412 to rotate. The displacement drive unit 413 is a drive motor and is driven by the displacement gear 412. The movable frame 410 is horizontally spaced in two, and each of the two movable frames 410 is provided with a corresponding displacement slider 411 and displacement gear 412. The two displacement gears 412 are connected by the same connecting rod, so that the two displacement gears 412 are coaxial and rotate synchronously.

[0076] Figure 12 This is a schematic diagram of the adsorption component of the present invention.

[0077] See Figures 9 to 12 and combined Figure 1 The adsorption assembly 420 includes a limiting plate 421 fixed to the movable frame 410, an adsorption telescopic cylinder 422 fixed to the limiting plate 421, a lifting plate 423 fixed to the adsorption telescopic cylinder 422, and multiple suction cups 424 fixed to the lifting plate 423. The adsorption telescopic cylinder 422 can drive the lifting plate 423 to move vertically up and down. When the movable frame 410 moves the adsorption assembly 420 above the film placement mechanism 30, the adsorption telescopic cylinder 422 drives the lifting plate 423 and the suction cups 424 to move downward, and the suction cups 424 adsorb the film, thereby placing the film on the upper surface of the curtain 90 on the curtain fixing mechanism 20. A cylinder is connected to the suction cup 424 so that the suction cup 424 can adsorb the film through negative pressure. Multiple suction cups 424 are provided, and the multiple suction cups 424 are arranged at horizontal intervals.

[0078] A guide rod 425 and a guide bearing 426 are provided between the limiting plate 421 and the lifting plate 423; the guide bearing 426 and the suction telescopic cylinder 422 are spaced apart in the horizontal direction to prevent the lifting plate 423 from rotating in the horizontal direction. The guide rod 425 extends vertically and slides vertically through the guide bearing 426.

[0079] In this embodiment, the lifting plate 423 is positioned below the limiting plate 421, and the lower end of the guide rod 425 is fixed to the lifting plate 423 so that the guide rod 425 extends upward from the lifting plate 423. The guide bearing 426 is fixed to the limiting plate 421. The upward extension of the guide rod 425 from the lifting plate 423 effectively prevents the lower end of the guide rod 425 from interfering with other structures of the bonding machine.

[0081] See Figures 9 to 17 and combined Figure 1 The pressure roller assembly 430 includes a pressure roller platform 431 fixed on a movable frame 410, a pressure roller connecting unit 432 connected to the pressure roller platform 431, and a roller 437 fixed on the pressure roller connecting unit 432. The pressure roller connecting unit 432 can drive the roller 437 to move vertically, so that the roller 437 presses against the film on the screen 90. The movable frame 410 drives the pressure roller platform 431 to move, so that the pressure roller connecting unit 432 drives the roller 437 to move to the edge of the film on the screen, and presses it against the film by moving downward through the pressure roller connecting unit 432. The movement of the movable frame 410 drives the roller 437 to roll on the film.

[0082] In this embodiment, the pressure roller connecting unit 432 includes an upper pressure plate 4321 connected to the pressure roller table 431, a second telescopic cylinder 4322 connected to the upper pressure plate 4321, and a lower pressure plate 4323 connected to the second telescopic cylinder 4322. The roller 437 is fixed to the lower pressure plate 4323, and the second telescopic cylinder 4322 is used to drive the lower pressure plate 4323 to move vertically. A pressure sensor is provided on the second telescopic cylinder 4322, or between the upper pressure plate 4321 and the lower pressure plate 4323, to detect the pressure of the roller 437 on the film on the curtain 90. The pressure sensor is electrically connected to the second telescopic cylinder 4322 so that the pressure on the film can be controlled by the second telescopic cylinder 4322.

[0083] Two pressure roller connecting units 432 are spaced laterally, and each of the two pressure roller connecting units 432 is respectively positioned at both ends of the roller 437. The two pressure roller connecting units 432 can be positioned relatively close to or far apart to limit rollers 437 of different sizes between the two pressure roller connecting units 432. Pressure rollers of different sizes can accommodate curtains 90 of different sizes and corresponding films.

[0084] The upper pressure plate 4321 is provided with a second slider 433, and a second slide rail 434 is fixed on the corresponding pressure roller table 431. The second slide rail 434 extends in the left and right direction, and the second slider 433 is slidably disposed on the second slide rail 434 to adjust the distance between the two pressure roller connecting units 432, thereby displaying rollers of different sizes between the two connecting units.

[0085] The pressure roller assembly 430 also includes a second lead screw 435 rotatably connected to the pressure roller table 431, and a roller changing drive unit 436 for driving the second lead screw 435 to rotate; two upper pressure plates 4321 are sleeved and threadedly connected to the second lead screw 435 so that they can move away from each other and move closer to each other, thereby allowing the lower pressure plate 4323 to be separably sleeved on the roller 437.

[0086] Figure 18 This is a schematic diagram of the structure of the card plate of the present invention. Figure 19 This is a schematic diagram of the structure of the roller of the present invention. Figure 20 This is a schematic diagram showing the position of the roller of the present invention on the support frame.

[0087] See Figures 9 to 20 and combined Figure 1 Roller shafts 4371 are provided at both ends of roller 437, and the roller shafts 4371 at both ends of roller 437 are coaxially arranged. Alternatively, roller shafts 4371 are inserted through roller 437, with both ends of roller shafts 4371 extending beyond both ends of roller 437. Two pressure roller connecting units 432 are arranged at transverse intervals, and the two lower pressure plates 4323 of the two pressure roller connecting units 432 are respectively sleeved on both ends of roller shafts 4371, thereby limiting roller 437 between the two lower pressure plates 4323.

[0088] The frame is equipped with multiple rollers 437 of different sizes, which are spaced apart longitudinally. In this embodiment, a support platform 14 is provided inside the frame to place and limit the rollers 437. The roller changing drive unit 436 drives the second lead screw 435 to rotate, thereby causing the two lower pressure plates 4323 to move away from or towards each other, so as to separably engage the rollers 437 of different sizes on the lower pressure plates 4323.

[0089] In one embodiment, the bottom end of the lower pressure plate 4323 is provided with a first through hole 4324; the first through hole 4324 is fitted around the outer periphery of the roller 4371, so that the roller 437 is displayed on the lower pressure plate 4323.

[0090] In this embodiment, the bottom end of the lower pressure plate 4323 is provided with a first through-hole 4324, which extends vertically or has an open lower end. A locking plate 438 is provided on the lower pressure plate 4323; the locking plate 438 is slidably connected to the lower pressure plate 4323 vertically; a second through-hole 4381 is provided on the locking plate 438; the second through-hole 4381 extends vertically, and the projections of the first through-hole 4324 and the second through-hole 4381 in the horizontal direction at least partially overlap; the locking plate 438 slides relative to the lower pressure plate 4323, causing the roller 4371 to engage between the sidewalls of the second through-hole 4381 and the second through-hole 4381.

[0091] In another embodiment, the lower pressure plate 4323 does not have a first card hole 4324, but only a second card hole 4381 is provided on the card plate 438.

[0092] A limit telescopic cylinder 439 is provided between the lower pressure plate 4323 and the clamping plate 438. The limit telescopic cylinder 439 is used to drive the clamping plate 438 to slide vertically. The lower pressure plate 4323 is provided with a guide slide rail extending vertically, and the clamping plate 438 is provided with a guide slider, which is slidably mounted on the guide slide rail vertically.

[0093] A ring groove 4372 is recessed on the circumference of the roller 4371, and the clamping plate 438 is at least partially attached to the lower pressure plate 4323 in the transverse direction. When the roller 4371 passes through the first clamping hole 4324 and the second clamping hole 4381, the two ends of the groove in the axial direction are close to the lower pressure plate 4323 and the clamping plate 438, respectively, so as to restrict the movement of the roller 437 in the transverse direction.

[0094] Figure 21 This is a schematic diagram of the membrane placement mechanism of the present invention. Figure 22 This is a structural schematic diagram of the sliding frame of the present invention from one perspective. Figure 23 This is a structural schematic diagram of the invention of the sliding frame from another perspective. Figure 24 This is a schematic diagram of the longitudinal positioning component on the positioning platform.

[0095] See Figures 21 to 24 and combined Figure 1 The diaphragm placement mechanism 30 includes a sliding frame 310 slidably mounted on a frame, a positioning stage 320 rotatably mounted on the sliding frame 310 about a transverse axis, and an angle drive assembly 330 for rotating and positioning the positioning stage 320. The positioning stage 320 is used to place the diaphragm, and a longitudinal positioning member 340 is provided at one longitudinal end of the positioning stage 320. The longitudinal positioning member 340 extends at least partially beyond the upper surface of the positioning stage 320 to limit the diaphragm on the positioning stage 320. The positioning stage 320 is provided with multiple rollers, all of which extend laterally and are spaced longitudinally. The rollers are capable of rotation, and the upper ends of the multiple rollers constitute the upper surface of the positioning stage 320.

[0096] After the diaphragm is placed on the positioning stage 320, the longitudinal positioning member 340 at one longitudinal end of the diaphragm can limit and position that end of the diaphragm. The angle driving component 330 can drive the positioning stage 320 to tilt downward, causing the upper surface of the positioning stage 320 to tilt downward, thereby causing the diaphragm on the positioning stage 320 to move downward or have a downward tendency to abut against the longitudinal positioning member 340.

[0097] The sliding frame 310 can slide to move the film on the positioning platform 320 to a preset position to align with the screen 90. The positioning platform 320 moves to directly above the screen placement platform 210, moving the film directly above the screen 90. After the adsorption assembly 420 adsorbs the film, the moving frame 410 moves the film placement mechanism 30 away from the pressure roller mechanism 40, thereby maintaining the position of the film above the screen 90 and ensuring alignment between the film and the screen 90. The adsorption assembly 420 adsorbs the side of the film facing the pressure roller mechanism 40. As the adsorption assembly 420 moves backward and the film is adsorbed onto it, the film will not wrinkle or bend during the backward movement of the adsorption assembly 420.

[0098] After the adsorption assembly 420 adsorbs the membrane at one end facing the pressure roller mechanism 40, the adsorption assembly 420 moves downward so that the end of the membrane facing the pressure roller mechanism 40 is pre-attached to the membrane. The pressure rollers on the pressure roller mechanism 40 longitudinally roll the membrane.

Figure 26 This is a structural schematic diagram of the positioning stage of the present invention from one perspective. Figure 27 This is a structural schematic diagram of the positioning stage of the present invention from another perspective.

[0100] See Figures 21 to 27 and combined Figure 1 The sliding frame 310 is also equipped with a position driving component, which drives the sliding frame 310 to move to a preset position on the curtain placement platform 210. A slider is fixed to the bottom of the sliding frame 310 for engaging with a movable slide rail, and this slider is slidably mounted on the slide rail. The position driving component includes a position gear 350 and a position driving unit 360. The position gear 350 meshes with a movable rack, and the position driving unit 360 is a drive motor, which is connected to the position gear 350 to drive the position gear 350 to rotate. Furthermore, the position driving unit 360 is a stepper electrode to control the sliding frame 310 to move to the preset position.

[0101] The pressure roller structure and the film placement mechanism 30 are arranged longitudinally at intervals; the pressure roller mechanism 40 is located on the side of the positioning platform 320 where the longitudinal positioning member 340 is provided. The positioning platform 320 is configured such that when the adsorption assembly 420 adsorbs the film, the positioning platform 320 is inclined downward toward the side facing the pressure roller mechanism 40, and the position driving assembly drives the sliding frame 310 to move, so as to drive the positioning platform 320 to move away from the pressure roller mechanism 40.

[0102] In this embodiment, a longitudinal driving unit 341 is connected to the longitudinal positioning member 340. The longitudinal driving unit 341 is fixed on the positioning stage 320 and located below the upper surface of the positioning stage 320. The longitudinal driving unit 341 is used to drive the longitudinal positioning member 340 to move, so that the longitudinal positioning member 340 can move to the point where its upper end exceeds the upper surface of the positioning stage 320, or the longitudinal positioning member 340 can move to the point where it is located below the upper surface of the positioning stage 320. In one embodiment, the longitudinal driving unit 341 and the longitudinal positioning member 340 are structured as a telescopic cylinder.

[0103] In this embodiment, a fixing block 342 is fixed on the positioning stage 320, and the fixing block 342 is located below the upper surface of the positioning stage 320; the positioning member includes a positioning section and a rotating section vertically connected to the positioning section; the rotating section is axially connected to the fixing block 342; the longitudinal driving unit 341 drives the positioning member to rotate on the fixing block 342, so that the positioning section can rotate to face the upper surface of the positioning stage 320, or the positioning member can be stored below the upper surface of the positioning stage 320.

[0104] In this embodiment, a rotating segment is disposed at one end of a positioning segment and passes through a fixed block 342. A positioning gear 343 is disposed at the end of the rotating segment facing away from the positioning segment. A positioning rack 344 is disposed on the positioning platform 320 and is slidably disposed on the positioning platform 320 along its own length direction. The positioning rack 344 meshes with the positioning gear 343. A longitudinal drive unit 341 is connected to the positioning rack 344 to drive the positioning rack 344 to slide. The longitudinal drive unit 341 is a drive motor or a telescopic cylinder.

[0105] The angle drive assembly 330 includes a placement shaft 331 rotatably connected to the sliding frame 310, and an angle drive unit 332 fixed to the sliding frame 310. A positioning stage 320 is fixedly connected to the placement shaft 331. The angle drive assembly 330 is driven by the placement shaft 331 to drive the placement shaft 331 to rotate, thereby limiting and adjusting the angle of the positioning stage 320 relative to the horizontal plane. The angle drive unit 332 is a drive motor and is driven by the placement shaft 331.

[0106] Figure 28 This is a structural schematic diagram of the lateral positioning component of the present invention from one perspective. Figure 29 This is a structural schematic diagram of the lateral positioning component of the present invention from another perspective. Figure 30 This is a schematic diagram of the structure of the lateral positioning unit of the present invention.

[0107] See Figures 21 to 30 and combined Figure 1In this embodiment, the positioning stage 320 is further provided with a transverse positioning assembly 370. The transverse positioning assembly 370 includes a transverse lead screw 371 rotatably mounted on the positioning stage 320, a transverse drive unit 372 for driving the transverse lead screw 371 to rotate, and two sets of transverse positioning units 380 sleeved on the transverse lead screw 371. The two sets of transverse positioning units 380 are spaced apart in the transverse direction and are threadedly connected to the transverse lead screw 371, so that when the transverse lead screw 371 rotates, the two sets of transverse positioning units 380 can move away from or closer to each other in the transverse direction. The upper end of the transverse positioning unit 380 extends beyond the upper surface of the positioning stage 320. The two sets of transverse positioning units 380 can move towards each other in the transverse direction, thereby stopping the transverse sides of diaphragms of different sizes, so as to position the diaphragms of different sizes in the transverse direction on the positioning stage 320.

[0108] The lateral positioning unit 380 includes a slide plate 381 sleeved on the lateral lead screw 371 and a lateral telescopic cylinder 382 fixed on the slide plate 381. The lateral telescopic cylinder extends vertically so that the rod of the lateral telescopic cylinder 382 can slide upward above the upper surface of the positioning table 320, or move downward so that the rod part of the lateral telescopic cylinder 382 can slide below the upper surface of the positioning table 320.

[0109] In this invention, multiple hooks 220 are arranged around the screen placement platform 210 and located on the upper surface of the screen placement platform 210. The hooks 220 are used to hook the frame strips 91 around the screen 90. The hook driving assembly 230 drives the hooks 220 to translate, thereby tightening the screen 90. The translation of the hooks 220 can tighten screens of different sizes. The film placement mechanism 30 is used to place and position films of different sizes, so that the laminating machine can adapt to the lamination of laser screens of different sizes.

[0110] The movable frame 410 is slidably mounted on the machine frame along the longitudinal direction. The adsorption component 420 drives the film to be placed on the upper surface of the screen 90. The pressure roller component 430 is configured to move with the movable frame 410 to roll on the upper surface of the film, thereby driving the film to be pasted on the screen 90. This achieves automatic pasting of the film on the screen 90 without the need for manual operation, improving production efficiency and saving time and costs.
