Description

Technical Field

[0001] The utility model belongs to the technical field of screen printing equipment, and particularly relates to a screen printing tooling. Background Art

[0002] As a widely used printing process, screen printing technology can be applied to the surface treatment of various materials, including but not limited to paper, plastic, metal, glass, etc. Traditional screen printing includes automatic screen printing equipment and manual screen printing equipment. Although automatic screen printing equipment is efficient, due to its complexity and high cost, it is not the best choice for small batch production. On the contrary, manual screen printing equipment is widely used in small batch production because of its low cost. However, after the screen printing plate of the existing manual screen printing equipment completes one-time downward screen printing, it is necessary to disassemble the screen printing plate before the printed matter can be taken out. This process not only increases the complexity of the operation process but also reduces the screen printing efficiency.

[0003] In response to this, the prior art has proposed a flipable screen printing plate device, which is provided with a counterweight flip assembly connected to the screen printing plate on the lifting adjustment assembly. During screen printing, the screen printing plate is held by hand and flipped to press on the printed matter for screen printing. After screen printing is completed, under the lever action of the counterweight flip assembly, the screen printing plate can be automatically lifted, facilitating the user to take the printed matter that has completed printing. However, during the screen printing process of this device, it is necessary to continuously press the screen printing plate manually, which makes the stability of the screen printing plate unable to be guaranteed, thereby affecting the screen printing accuracy; and it also increases the difficulty of manual operation. Especially during long-term continuous operation, the operator is prone to fatigue. In addition, if the position or weight of the counterweight assembly (counterweight block) is inappropriate, it may cause the screen printing plate not to accurately return to the required height after screen printing is completed, or to shake during use.

[0027] As Figures 1 to 3 shown, a screen printing tooling includes:

[0028] A workbench 100;

[0029] A screen plate clamping structure 200, which is arranged above the workbench 100;

[0030] The flipping assembly 300 is provided on the workbench 100. It includes a support member 310, a first limiting member 320, and a hinge structure 330. The support member 310 is provided on the opposite side of the screen plate clamping structure 200. The first limiting member 320 is connected to the support member 310 and is located below the hinge structure 330. The hinge structure 330 is respectively connected to the support member 310 and the screen plate clamping structure 200, and can drive the screen plate clamping structure 200 to rotate relative to the support member 310. When the screen plate clamping structure 200 rotates to the working position, the first limiting member 320 forms a support for the hinge structure 330. Through the setting and cooperation of the flipping assembly 300, on the one hand, it enables the operator to manually and easily flip the screen plate clamping structure 200, and the product can be taken out without completely disassembling the screen printing plate 600, simplifying the operation process and the overall structure; on the other hand, when the screen plate clamping structure 200 rotates to the working position, the first limiting member 320 can form a support for the hinge structure 330, ensuring the stability of the screen plate 600 during the screen printing process, and there is no need for manual continuous pressing of the screen plate 600, which not only reduces the work burden and fatigue of the operator, but also improves the screen printing accuracy.

[0031] Specifically, as Figure 1 , Figure 2 , Figure 4 shown, in this embodiment, the workbench 100 is rectangular, and a workpiece clamping assembly 500 is provided thereon. The workpiece clamping assembly 500 includes a guide rail 510 detachably provided on the workbench 100, and a workpiece fixing seat 520 movably connected to the guide rail 510. When the workpiece fixing seat 520 moves along the guide rail 510, the distance between the workpiece 700 and the screen plate clamping structure 200 can be adjusted, thereby realizing the adjustment of the position of the workpiece 700 and meeting the requirements of screen printing position adjustment.

[0032] Preferably, in this embodiment, the workpiece fixing seat 520 is rectangular, and a plurality of limiting blocks 530 are movably provided thereon, arranged along the circumferential direction of the workpiece fixing seat 520, and move towards the workpiece 700 under the drive of a driving member to realize the stable clamping of the workpiece 700, thereby ensuring the stability of the workpiece 700 during the screen printing process.

[0033] To realize the clamping of the screen plate 600, in this embodiment, a screen plate clamping structure 200 is further provided above the workpiece fixing seat 520. The screen plate clamping structure 200 includes a mounting frame 210 and a fixing member 220. The mounting frame 210 is a U-shaped long steel bar with a mounting groove 211 for accommodating the screen plate 600. The fixing member 220 is a stud, movably provided on the mounting frame 210 and extending into the mounting groove 211. When the fixing member 220 moves, the size of the mounting groove 211 can be adjusted, thereby realizing the fixation of screen plates 600 of different specifications and effectively improving the adaptability of the screen printing tooling.

[0034] Preferably, in the present embodiment, the mounting bracket 210 is horizontally arranged and parallel to the workpiece fixing base 520. A plurality of fixing members 220 are provided, arranged along the length direction of the mounting bracket 210, and vertically and movably arranged on the mounting bracket 210. Moreover, a plurality of threaded holes for threadedly connecting with the fixing members 220 are provided on the mounting bracket 210. Through the arrangement of the plurality of fixing members 220, multi-point fixing of the stencil 600 is achieved, further improving the reliability of the fixing of the stencil 600.

[0035] In the present embodiment, a second limiting member 340 movably passing through the mounting groove 211 and extending towards the support member 310 is further provided on the mounting bracket 210. When the second limiting member 340 moves to abut against the surface of the support member 310, the rotation of the stencil clamping structure 200 can be restricted. Further ensuring the stability of the stencil clamping structure 200 during screen printing.

[0036] Preferably, in the present embodiment, the second limiting member 340 is a stud, which vertically passes through the middle position of the mounting bracket 210, and threaded holes for threadedly connecting with the second limiting member 340 are provided on the mounting bracket 210. When it is necessary to flip the stencil 600, the second limiting member 340 can be loosened to separate the second limiting member 340 from the support member 310. When the stencil 600 rotates to the working position, the second limiting member 340 is tightened until it abuts against the surface of the support member 310, thereby restricting the rotation of the stencil 600.

[0037] As Figures 1 to 3 shown, in the present embodiment, the stencil clamping structure 200 further has an avoidance groove 230 for the first limiting member 320 to extend into. The avoidance groove 230 is L-shaped, including a first groove 231 and a second groove 232 that are perpendicular to each other and communicate. Moreover, the openings of the first groove 231 and the second groove 232 are arranged oppositely. When the stencil clamping structure 200 rotates, the first limiting member 320 rotates between the first groove 231 and the second groove 232. Effectively avoiding interference with the rotation of the stencil clamping structure 200, ensuring the position accuracy of the stencil clamping structure 200 during rotation, and enhancing stability.

[0038] Preferably, in the present embodiment, the widths of the openings of the first groove 231 and the second groove 232 are greater than the width of the first limiting member 320, and the number of the avoidance grooves 230 is adapted to the number of the first limiting members 320.

[0039] To facilitate the flipping of the stencil clamping structure 200, in this embodiment, a flipping assembly 300 is provided. The flipping assembly 300 is respectively connected to the stencil clamping structure 200 and the adjusting assembly 400. The flipping assembly 300 includes a support member 310, a first limiting member 320, and a hinge structure 330. Among them, the support member 310 serves as the support structure of the stencil clamping structure 200. The first limiting member 320 is used to limit the position of the stencil clamping structure 200 so that the stencil clamping structure 200 can maintain a horizontal state when in the working position. The hinge structure 330 serves as a connecting structure that enables the support member 310 and the stencil clamping structure 200 to form a rotatable connection, so that the operator can manually flip the stencil clamping structure 200 easily without completely disassembling the screen printing stencil 600 to remove the product, effectively simplifying the operation process and the overall structure of the tooling.

[0040] Preferably, in this embodiment, the support member 310 is a strip-shaped plate, which is arranged on the opposite side of the mounting frame 210 and is detachably connected to the first moving block 440 through a fastener. Moreover, the length of the support member 310 is adapted to the length of the mounting frame 210 to ensure the stability of both ends when the stencil clamping structure 200 flips.

[0041] In this embodiment, the first limiting member 320 is in the shape of a convex platform block and is located below the hinge structure 330. One end of it is detachably connected to the support member 310 through a fastener, and the other end extends towards the direction close to the stencil clamping structure 200 and extends into the first groove 231 to be parallel to the workbench 100. On the one hand, it realizes the rapid positioning of the working position of the stencil clamping structure 200, improving the accuracy and efficiency when the stencil clamping structure 200 resets. On the other hand, it enables the stencil 600 to maintain a horizontal state and be more stable when in the working position, further improving the screen printing accuracy.

[0042] Preferably, in this embodiment, there are two groups of the first limiting members 320, which are respectively detachably arranged at both ends of the support member 310 to ensure the stability when the stencil clamping structure 200 flips.

[0043] In this embodiment, the hinge structure 330 includes a first connecting portion 331 and a second connecting portion 332 that are hinged to each other. The first connecting portion 331 is detachably connected to the support member 310 through a fastener, and the second connecting portion 332 is detachably connected to the mounting frame 210 of the stencil clamping structure 200 through a fastener. When the stencil clamping structure 200 rotates to the working position, the first limiting member 320 fits with the first connecting portion 331 and the second connecting portion 332, and forms a support with the first hinge structure 330. Furthermore, it can limit the continuous rotation of the hinge structure 330, effectively ensuring the stability of the placement of the stencil 600. In addition, through the detachable connection design, the convenience of maintaining and replacing components is effectively improved.

[0044] In this embodiment, the hinge structure 330 is a positioning hinge. By using the positioning hinge as the hinge structure 330, the operator can flip the screen plate 600 and it can stay at any position. Thus, the operator does not need to continuously hold the screen plate 600 after flipping, effectively improving the operation convenience, reducing the work burden of the operator, and reducing the sense of fatigue.

[0045] To meet the screen printing requirements of products with different specifications, in this embodiment, an adjusting component 400 is further provided. The adjusting component 400 is arranged on the adjacent side of the workpiece clamping component 500. It includes a longitudinal rod 410 detachably arranged on the workbench 100, and a moving frame 420 movably arranged on the longitudinal rod 410. And the support 310 is connected to the moving frame 420. When the moving part moves along the length direction of the longitudinal rod 410, it can drive the screen plate clamping structure 200 to move longitudinally. This design enables the screen plate clamping structure 200 to adjust the longitudinal height as needed, thereby meeting the screen printing requirements of workpieces 700 with different heights, and increasing the flexibility and adaptability of the equipment.

[0046] Preferably, in this embodiment, there are two groups of longitudinal rods 410 which are respectively vertically arranged on the workbench 100 and form a detachable connection with the workbench 100 through mounting seats. The two ends of the moving frame 420 are provided with second moving blocks detachably connected to the longitudinal rod 410, and locking bolts are arranged on the second moving blocks. When the operator moves the moving frame 420 to the required height, turning the locking bolts can fix the moving frame 420 to the longitudinal rod 410. This design effectively ensures the stability of the fixation of the moving frame 420 to the longitudinal rod 410, and thus ensures the stability during screen printing.

[0047] To prevent the second moving block from rotating, in this embodiment, a limiting strip is further arranged on the longitudinal rod 410. The limiting strip is rectangular and extends along the length direction of the longitudinal rod 410, and a connecting groove for forming a concave-convex fit with the limiting strip is arranged on the second moving block. This design enables the second moving block to only move along the length direction of the longitudinal rod 410.

[0048] In this embodiment, a cross bar 430 perpendicular to the longitudinal rod 410 is further arranged on the moving frame 420, and a first moving block 440 movably arranged on the cross bar 430. The first moving block 440 is detachably connected to the support 310. When the first moving block 440 moves along the length direction of the cross bar 430, it can drive the screen plate clamping structure 200 to move horizontally. This design enables the screen plate clamping structure 200 to adjust the horizontal position as needed, thereby meeting the screen printing requirements of workpieces 700 with different widths or different positions of the workpiece 700, and further increasing the flexibility and adaptability of the equipment.

[0049] In this embodiment, the first moving block 440 has the same structure as the second moving block, and a locking bolt is also provided thereon. After the operator moves the first moving block 440 to a specified position, rotating the locking bolt can fix the first moving block 440 to the cross bar 430. This design effectively ensures the stability of the fixation of the first moving block 440 to the cross bar 430, and thus ensures the stability during screen printing.

[0050] To prevent the first moving block 440 from rotating, in this embodiment, a limiting strip is also provided on the cross bar 430. The limiting strip is rectangular and extends along the length direction of the cross bar 430, and a connecting groove that forms a concave-convex fit with the limiting strip is provided on the first moving block 440. This design enables the first moving block 440 to only move along the length direction of the cross bar 430.
