Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, and in particular to a high-precision screen printing device. Background Technology

[0002] Screen printing, a type of stencil printing, is one of the four major printing methods along with offset printing, letterpress printing, and gravure printing. Stencil printing includes methods such as stencil printing, die-cutting, spray printing, and screen printing. The working principle of stencil printing is as follows: A printing plate, such as a paper stencil or other plate base, has perforations that allow ink to pass through. During printing, pressure is applied to force ink through these perforations onto the substrate, such as paper or ceramics, to form images or text. During printing, a squeegee presses the ink through the mesh of the image area onto the substrate, creating an image identical to the original. Screen printing equipment is simple, easy to operate, and the printing and plate-making processes are simple and inexpensive. It is highly adaptable and has a wide range of applications, commonly including: color paintings, posters, business cards, book covers, product labels, and printed textiles.

[0037] 6—Receiving mechanism. Detailed Implementation

[0038] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0039] like Figures 1 to 13 As shown, the present invention provides a high-precision screen printing equipment, including an unwinding mechanism 1 for feeding film material, a correction mechanism 2 for correcting the deviation of the film material, a screen printing mechanism 3 for screen printing the corrected film material, a detection mechanism 4 for detecting the screen-printed film material, and a drying mechanism 5 for drying the detected film material. The drying mechanism 5 is provided with a winding mechanism 6 for winding the dried film material.

[0040] During operation, the film roll is installed on the unwinding mechanism 1 and unwound. After the film is unwound, it is first corrected by the web-aligning mechanism 2, and then screen printing is performed. The screen-printed film is inspected to check whether the printing position meets the requirements. The inspected film is then transferred to the drying mechanism 5 for drying, and finally rewinded by the winding mechanism 6. The entire process is automated, thereby improving screen printing efficiency.

[0041] In this embodiment, the correction mechanism 2 used is a conventional structure, which will not be described in detail here.

[0042] In this embodiment, the screen printing mechanism 3 includes a worktable 31, a screen clamping mechanism 32 movably disposed on the worktable 31, a first driver 33 drivenly connected to the screen clamping mechanism 32, a squeegee mechanism 34 movably disposed on the worktable 31, and a second driver 35 drivenly connected to the squeegee mechanism 34. The worktable 31 is used to support sheet metal parts placed outside. The first driver 33 is located in front of the second driver 35. The screen clamping mechanism 32 and the squeegee mechanism 34 work together.

[0043] During operation, the sheet material is first placed on the worktable 31, and the screen clamping mechanism 32 clamps and fixes the screen plate, positioning it above the sheet material. The first driver 33 drives the screen clamping mechanism 32 to move along the length of the worktable 31, bringing the screen plate closer to and adhering it to the sheet material. The second driver 35 drives the squeegee mechanism 34 to move along the length of the worktable 31, with the squeegee mechanism 34 positioned above the screen clamping mechanism 32. The second driver 35 drives the squeegee mechanism 34 to move back and forth on the screen plate. The squeegee mechanism 34 squeezes and scrapes the ink pre-applied to the screen plate, allowing the ink to pass through the mesh and be evenly coated onto the sheet material, thus completing the screen printing process. The entire process is automated, significantly reducing labor costs. This invention features a compact and rationally designed structure, enabling automated screen printing, improving printing efficiency and accuracy, and easily meeting the needs of mass production.

[0044] The mesh clamping mechanism 32 of this embodiment includes a base 311, an adjustment component 322 movably disposed on the base 311, and a first drive component 323 drivenly connected to the adjustment component 322. The adjustment component 322 includes a base 3221, a first clamping groove 3222 and a second clamping groove 3223 movably disposed on the base 3221, a first nut 3224 and a second nut 3225 respectively disposed on the first clamping groove 3222 and the second clamping groove 3223, a first screw 3226 and a second screw 3227 respectively threadedly connected to the first nut 3224 and the second nut 3225, and a first clamping block 3228 and a second clamping block 3229 respectively disposed on the first screw 3226 and the second screw 3227. The first clamping groove 3222 and the second clamping groove 3223 are close to or far away from each other along the length direction of the base 3221. An ion air bar 324 is disposed on the side of the base 311 away from the adjustment component 322. Specifically, during operation, the first drive assembly 323 drives the adjustment assembly 322 to move horizontally along the length of the base 311, thereby adjusting the adjustment assembly 322 to a suitable position. Furthermore, the first clamping groove 3222 and the second clamping groove 3223 move closer to or further away from each other along the length of the base 3221. During fixing, the mesh plate is placed between the first clamping groove 3222 and the second clamping groove 3223. The outer side and bottom of the mesh plate are engaged and fixed to the inner walls of the first clamping groove 3222 and the second clamping groove 3223. By rotating the first screw 3226 clockwise and threading it with the first nut 3224, the first clamping block 3228 moves downward, further clamping and fixing the first clamping block 3228 to the top of the mesh plate. By rotating the second screw 3227 clockwise and... The second screw 3227 is threadedly connected to the second nut 3225, thereby causing the second clamping block 3229 to move downwards. This further clamps and fixes the second clamping block 3229 to the top of the screen, thus providing multi-directional positional fixation for the screen, reducing the possibility of screen displacement, and improving printing quality. When the screen needs to be replaced, the first screw 3226 is rotated counterclockwise to move it away from the first nut 3224, thereby causing the first clamping block 3228 to move upwards and away from the screen. Similarly, the second screw 3227 is rotated counterclockwise to move it away from the second nut 3225, thereby causing the second clamping block 3229 to move upwards and away from the screen. This facilitates the removal of the screen, improving practicality and connection reliability. Ionizing air bar 324 is located on the back of the base 311. When working, the ionizing air bar 324 generates air masses with positive and negative charges, which neutralize the charges on the surface of the mesh plate, thereby eliminating static electricity.

[0045] In this embodiment, both the first clamping groove 3222 and the second clamping groove 3223 are C-shaped. The first clamping groove 3222 is provided with a first slider 32210, and the second clamping groove 3223 is provided with a second slider 32211. The base 3221 is laterally provided with a guide rail 32212. The first clamping groove 3222 is slidably connected to the guide rail 32212 through the first slider 32210, and the second clamping groove 3223 is slidably connected to the guide rail 32212 through the second slider 32211. Specifically, the C-shaped design of both the first clamping groove 3222 and the second clamping groove 3223 better wraps around the outer edge of the supporting mesh plate, enhancing positioning stability. The first clamping groove 3222 is slidably connected to the guide rail 32212 through the first slider 32210, and the second clamping groove 3223 is slidably connected to the guide rail 32212 through the second slider 32211, ensuring smooth and stable movement.

[0046] In this embodiment, limit blocks 32213 are provided at both ends of the base 3221. The limit blocks 32213 prevent contact with the first slider 32210 and the second slider 32211. Specifically, the limit blocks 32213 are installed at both ends of the base 3221. When the first clamping groove 3222 and the second clamping groove 3223 slide on the base 3221, the limit blocks 32213 prevent contact with the first slider 32210 and the second slider 32211, thus playing a good blocking and limiting role and effectively preventing the first slider 32210 and the second slider 32211 from sliding excessively and accidentally falling off the guide rail 32212.

[0047] The first drive assembly 323 in this embodiment includes a ball screw 3231, a servo motor 3232 driven and connected to the ball screw 3231, a screw nut 3233 threadedly connected to the ball screw 3231, a first movable seat 3234 connected to the screw nut 3233, and a connector 3235 disposed on the first movable seat 3234. The first movable seat 3234 is connected to the base 3221 through the connector 3235. Specifically, the servo motor 3232 drives the ball screw 3231 to rotate, and the rotating ball screw 3231 drives the screw nut 3233 to move, thereby driving the first movable seat 3234 connected to the screw nut 3233 to move. The first movable seat 3234 is connected to the base 3221 through the connector 3235, thereby realizing that the first drive assembly 323 drives the adjustment assembly 322 to move horizontally along the machine base 311, which has a high degree of intelligence.

[0048] The scraper mechanism 34 in this embodiment includes a stand 341, a scraper assembly 342 movably disposed on the stand 341, a height adjustment assembly 343 drivenly connected to the scraper assembly 342, and a second drive assembly 344 drivenly connected to the height adjustment assembly 343. The scraper assembly 342 includes a rod 3421, a sliding seat 3422 slidably disposed on the rod 3421, a scraper 3423 disposed on the sliding seat 3422, a bracket 3424 disposed on the sliding seat 3422, and a bracket 3424 disposed on the bracket. The connector 3425 of 3424, the sliding seat 3422 is inverted U-shaped and slides against the rod 3421, the rod 3421 is provided with a connection hole 3426, the connection hole 3426 is provided in multiple ways, the multiple connection holes 3426 are arranged at intervals along the length direction of the rod 3421, the connector 3425 passes through the bracket 3424 and the sliding seat 3422 in sequence and is threaded into the connection hole 3426 to fasten the bracket 3424, the sliding seat 3422 and the rod 3421. Specifically, during operation, the second drive assembly 344 and the height adjustment assembly 343 are both electrically connected to the control system, enabling intelligent and precise control. The second drive assembly 344 drives the height adjustment assembly 343 to move downward relative to the stand 341, further driving the scraper assembly 342 closer to the substrate via the height adjustment assembly 343. The connector 3425 passes through the bracket 3424 and the sliding seat 3422 in sequence and is threaded into the connecting hole 3426. Moreover, multiple connecting holes 3426 are arranged at intervals along the length of the rod 3421, thereby fastening the bracket 3424, the sliding seat 3422 and the rod 3421, effectively adjusting the working position of the scraper 3423 on the rod 3421. The adjustment effect is significant, ensuring that the scraper 3423 applies sufficient pressure to the substrate.

[0049] In this embodiment, the bracket 3424 is provided with an elastic clamping arm 3427 at one end near the sliding seat 3422. The sliding seat 3422 is provided with a receiving groove 3428, which is recessed from the surface of the sliding seat 3422 and arranged along the length of the sliding seat 3422. The elastic clamping arm 3427 is received and abutted within the receiving groove 3428. Specifically, the bracket 3424 is received and abutted within the receiving groove 3428 by the elastic clamping arm 3427, thereby achieving a fixed connection between the bracket 3424 and the sliding seat 3422, resulting in good structural stability.

[0050] The height adjustment component 343 of this embodiment includes a connecting seat 3431, a lifting cylinder 3432 disposed on the connecting seat 3431, and an assembly seat 3433 disposed on the output end of the lifting cylinder 3432. The assembly seat 3433 is connected to the rod body 3421, and the connecting seat 3431 is connected to the second drive component 344. Specifically, the second drive component 344 drives the lifting cylinder 3432 to move up and down through the connecting seat 3431. The lifting cylinder 3432 is connected to the rod body 3421 through the assembly seat 3433, resulting in a reasonable and compact structural design.

[0051] The second drive assembly 344 in this embodiment includes a second movable seat 3441, a drive cylinder 3442 drivenly connected to the second movable seat 3441, an abutment block 3443 disposed on the drive cylinder 3442, and a micrometer 3444 disposed on the second movable seat 3441. The measuring end of the micrometer 3444 abuts against the abutment block 3443. Specifically, the drive cylinder 3442 drives the second movable seat 3441 to move up and down. The abutment block 3443 is disposed on the outside of the drive cylinder 3442. When the measuring end of the micrometer 3444 abuts against the abutment block 3443, the longitudinal position of the second movable seat 3441 can be adjusted more precisely due to the micrometer 3444, so as to accurately sense and detect the real-time position of the second movable seat 3441.

[0052] In this embodiment, the sliding seat 3422 has a mounting hole 3429, and a mounting screw 34210 is provided in the mounting hole 3429.

[0054] Working principle of inspection mechanism 4: The printed film is transferred to inspection mechanism 4. The braking parameters of traction motor 49 and drive motor 413 are set through control panel 416. Traction motor 49 controls support block 47 to reciprocate along slide 46 via traction wire 48, moving drag chain 411, thereby driving camera 415 to move freely in the Y direction. When traction motor 49 rotates in the positive direction, traction wire 48 pulls support block 47 to move camera 415 in the positive Y direction. When traction motor 49 rotates in the reverse direction, traction wire 48 pulls support block 47 to move camera 415 in the negative Y direction. Drive motor 413 directly drives drag chain 411 to circulate camera 415 in the X direction, thereby achieving all-round shooting of film by camera 415. Computer analyzes the screen printing defect detection data of the captured printed film image to determine whether the printing is qualified. If the printing is unqualified, the position is marked and then moved to drying mechanism 5; if the printing is qualified, the film is moved to drying mechanism 5.

[0055] Specifically, the cable chain 411 is reinforced on the cable chain frame 410 by a limiting bracket 412, and the cable chain 411 is electrically connected to a drive motor 413 via a guide wire 414. The cable chain 411 is composed of several section plates 4112, which are connected by locking rods 4113. The first section plate 4112 is connected to a first floating head 4111, and the last section plate 4112 is connected to a second floating head 4114. The cable chain 411 has advantages such as easy maintenance, long service life, and neat wiring. It also helps to organize wiring, reduce cable or pipeline failures and maintenance time, and improve equipment availability and efficiency.

[0056] Furthermore, both the first floating head 4111 and the second floating head 4114 are rotatably connected to the section plate 4112 via a rotating shaft, and the rotation angle of the first floating head 4111 and the second floating head 4114 is 0° to 90°. The first floating head 411111 and the second floating head 4114 not only reduce errors, protect related components, maintain stable operation of the equipment, and extend the service life of the equipment, but also have the advantages of small size, easy installation, high durability, and high pressure resistance, effectively improving the stability of operation, thereby making the recording of the camera 41511 clearer, so as to enable accurate and efficient detection and analysis.

The winding mechanism 6 is disposed in the middle of the frame 51.

[0061] When the drying mechanism 5 is working, the film is fed into the drying assembly 566 through the feeding assembly 52. ​​The film is dried and shaped by the drying assembly 56. The dried film is then transported to the second cooling assembly 55 for a first air-cooling treatment, and then sent to the first cooling assembly 53 through the discharging assembly 54 for a second air-cooling treatment. After the two air-cooling treatments, the film is fully cooled and then wound by an external feeding mechanism. This utility model has a compact structure and reasonable design, achieving sufficient and efficient cooling of the film, improving the cooling quality and efficiency of the film.

The membrane is then discharged from the inner cavity 561 through the second opening 567. The first opening 566 and the second opening 567 are used to realize the feeding and discharging of the membrane, ensuring that the membrane is fully dried in the relatively closed inner cavity 561, thereby improving drying efficiency. Preferably, the number of infrared heating tubes 565 is 14, with 7 infrared heating tubes 565 spaced apart at the top of the inner cavity 561 and 7 infrared heating tubes 565 spaced apart at the bottom of the inner cavity 561. This arrangement ensures that the upper and lower surfaces of the membrane in the inner cavity 561 are heated evenly, resulting in a thorough and efficient drying effect.

Specifically, the first exhaust fan 534 is turned on. The first exhaust fan 534 is connected to the first cooling box 531 through the first exhaust pipe 535. Since the first cooling box 531 and the first cooling channel 532 are interconnected, the membrane enters the first cooling channel 532 through the third opening 536 and is then guided and transported by the lower guide roller. This effectively draws the hot air out to the outside environment with the help of the first exhaust fan 534, accelerates the air circulation rate, improves ventilation performance, and enhances the cooling effect on the membrane.

[0064] The second cooling assembly 55 in this embodiment includes a second cooling box 551, a second cooling channel 552 communicating with the second cooling box 551, an upper guide roller 553 rotatably disposed in the second cooling channel 552, a second exhaust fan 554 disposed in the second cooling box 551, and a second exhaust pipe 555 disposed in the second exhaust fan 554.

A second transition wheel 58 is disposed between the second cooling assembly 55 and the drying assembly 56. A fourth opening 556 is disposed on the outer side of the second cooling channel 552. Specifically, the second exhaust fan 554 is turned on. The second exhaust fan 554 is connected to the second cooling box 551 through the second exhaust pipe 555. Since the second cooling box 551 and the second cooling channel 552 are interconnected, the membrane is conveyed to the fourth opening 556 through the rotation of the second transition wheel 58 and enters the second cooling channel 552. Then, the membrane is guided and transported by the upper guide roller 553. The hot air is effectively drawn out to the outside environment by the second exhaust fan 554, which accelerates the air circulation rate, improves ventilation performance, and enhances the cooling effect on the membrane.
