Description

Technical Field

[0001] This invention relates to the field of screen printing technology, and in particular to a screen frame clamping device. Background Technology

[0002] refer to Figure 1 The screen frame (0) is an essential tool in screen printing. Ideally, the screen frame should maintain a rectangular shape, consisting of the front border (01), back border (02), left border (03), and right border (04). (Reference) Figure 2 During the frame manufacturing process, due to unavoidable manufacturing errors, or after a period of use, the frame shape may undergo slight deformation due to stress. For example, the left frame 03 may tilt slightly to the right, so that the angle α formed by the left frame 03 and the front frame 01 is no longer 90 degrees. As time goes on, the angle α continues to change.

[0003] In the screen printing process, fixtures are needed to hold the screen frame. To accommodate changes in the shape of the screen frame, the fixtures must be designed with adjustable clamping posture, meaning that the fixtures can firmly hold the screen frame regardless of its shape. Currently, the clamping effect of fixtures used to hold screen frames is not ideal and cannot meet the clamping requirements of the screen frame. Summary of the Invention

[0004] One of the technical problems to be solved by the present invention is: how to design a wire mesh frame clamping device so as to be able to clamp and fix the wire mesh frame even when the shape of the wire mesh frame changes.

[0007] One end of each of the two pairs of hinge assemblies is connected to the first cylinder and the second cylinder respectively, and the other end passes through the left side plate and the left mounting plate in sequence and is connected to one side of the left pressure plate assembly. The two first contacts are respectively located at the front and rear ends of the other side of the left pressure plate assembly.

[0008] The right clamping component includes a right mounting plate and a right pressure plate assembly mounted on the left side of the right mounting plate. Two second contacts are mounted on the side of the right pressure plate assembly near the left clamping component.

[0009] When the first cylinder and the second cylinder apply clamping force to the left pressure plate assembly through two pairs of hinge assemblies, the two first contacts push the mesh frame against the two second contacts, so that the mesh frame is horizontally fixed on the worktable between the left pressure plate assembly and the right mounting plate assembly.

[0010] In some embodiments, the hinge assembly includes: a connecting rod, a concave block, a bolt, and a drum-shaped block;

[0023] In some embodiments, the right clamping component further includes a third bracket, a fourth bracket, a fifth cylinder, and a sixth cylinder. The third bracket and the fourth bracket are respectively disposed on the left side wall of the right mounting plate, the fifth cylinder is mounted on the third bracket, and the sixth cylinder is mounted on the fourth bracket.

[0024] In some embodiments, the front guide rail component includes: a front guide rail, a first front slider, a first front connecting block, a front bracket, a front pin, a second front slider, and a second front connecting block;

[0025] The front guide rail is mounted on the front side of the worktable. The first slider is movably mounted on the front side of the front guide rail. The first front connecting block includes a first front transverse block and a first front vertical block that are perpendicular to each other and stacked. The first front transverse block covers the first front slider. The first front vertical block is connected to the left side wall of the front end of the left mounting plate. The second front connecting block includes a second front transverse block and a second front vertical block that are perpendicular to each other and stacked. The second front slider is mounted on the front side of the front guide rail. The second front transverse block covers the second front slider. The second front vertical block covers the right side wall of the front end of the right mounting plate.

[0026] The upper end face of the front guide rail has several first positioning holes evenly distributed along its length for vertical insertion of the front pin.

[0027] The front bracket is vertically mounted on the first front vertical block, and the front pin passes vertically through the front bracket and is inserted into the first positioning hole.

[0028] In some embodiments, the rear guide rail component includes: a rear horizontal guide rail, a first rear slider, a first rear connecting block, a rear bracket, a rear pin, a second rear slider, and a second rear connecting block.

[0029] The rear horizontal guide rail is installed on the rear side of the worktable. The first rear connecting block includes a first rear transverse block and a first rear vertical block that are perpendicular to each other and stacked. The first rear slider is movably disposed on the rear side of the rear guide rail.

[0031] The upper surface of the rear horizontal guide rail is evenly distributed with several second positioning holes along the length direction; the rear bracket is vertically installed on the first rear vertical block, and the rear pin passes vertically through the rear bracket and is inserted into the second positioning hole.

[0032] In some embodiments, the first cylinder and the second cylinder are of the same type.

[0033] The mesh frame adjustment device disclosed in this invention achieves the following technical effects: A first cylinder and a second cylinder each drive a set of hinge assemblies, which are connected to the front and rear sides of the left pressure plate assembly. At the front and rear ends of the right side of the second vertical plate of the left pressure plate assembly, a first contact is provided. The two first contacts abut against the left edge of the mesh frame. If the left edge deflects (to the right or left) relative to its ideal position (the ideal position is when the left edge is perpendicular to both the front and rear edges), the two hinge assemblies can push the left pressure plate assembly to deflect, making the angle of the left pressure plate assembly the same as that of the left edge. Then, under the thrust of the first and second cylinders, the two first contacts abut against the left side of the left edge. Since the right pressure plate assembly is fixed horizontally, even if the left edge of the mesh frame undergoes a slight dynamic deflection, this mesh frame adjustment device can still dynamically adjust and fix the mesh frame in the horizontal plane. Vertically, the other four cylinders of the left and right clamping components fix the mesh frame adjustment device to the worktable. It should be noted that if any side of the frame is slightly deflected, the clamping component containing two sets of hinge assemblies can be pressed against the side wall of the frame that is slightly deflected, so that the frame is firmly clamped and fixed.

[0062] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0063] refer to Figure 3 In some embodiments, the wire mesh clamping device disclosed in this invention includes: a worktable 10, a front guide rail component 20 and a rear guide rail component 30 arranged parallel to each other on the worktable 10, and a left clamping component 40 and a right clamping component 50 arranged vertically between the front guide rail component 20 and the rear guide rail component 30. (See reference) Figure 4 and Figure 6 The left clamping component 40 includes: a first cylinder 401, a second cylinder 402, a left side plate 403, a left mounting plate 404, two pairs of hinge assemblies 410, a left pressure plate assembly 420, and two first contacts 405. Each pair of hinge assemblies 410 (see [link to specific embodiments of hinge assembly 410]) Figures 7 to 10One end of each cylinder (described in detail later) is connected to the first cylinder 401 and the second cylinder 402, and the other end passes through the left side plate 403 and the left mounting plate 404 before being connected to one side of the left pressure plate assembly 420 (a specific embodiment of the left pressure plate assembly 420 will be described in detail later). On the other side of the left pressure plate assembly 420, two first contacts 405 are installed. Figure 4 The image shows one of the first contacts, 405. Figure 6 The other first contact 405 is not shown. When gas is introduced into the first cylinder 401 and the second cylinder 402 respectively, the first cylinder 401 applies thrust to the front end of the left pressure plate assembly 420 through the first set of hinge assemblies 410, and the second cylinder 402 applies thrust to the rear end of the left pressure plate assembly 420 through the second set of hinge assemblies 410. Since the two first contacts 405 are respectively located at the front and rear ends of the left pressure plate assembly 420, the thrust of the first cylinder 401 and the second cylinder 402 ultimately acts on the two first contacts 405 respectively, and then acts on the left side frame 03 of the mesh frame 0 through the two first contacts 405. It is understandable that if the left side frame 03 experiences a situation as described in the background art... Figure 2 As shown in the rightward tilt (or leftward tilt) configuration, the first cylinder 401 and the second cylinder 402 push the front and rear ends of the left pressure plate assembly 420 through two sets of hinge assemblies 410, causing the left side frame 03 to deflect. The angle of deflection and Figure 2 Since α is the same, the two first contacts 405 can still firmly abut against the left side of the left frame 03, which has already deflected by α, and transmit the thrust of the first cylinder 401 and the second cylinder 402 to the left side of the left frame 03, applying a clamping force to the mesh frame 0 from the left side. In addition, because Figure 3 A right clamping member 50 is provided on the right side of the right frame 04 of the middle mesh frame. Therefore, when lateral pressure is applied to the left frame 03, the mesh frame 0 is pressed against the right clamping member 50 in the horizontal plane, so that the mesh frame 0 is clamped and fixed in the horizontal plane by the left clamping member 40 and the right clamping member 50. In this application, the first cylinder 401 and the second cylinder 402 are preferably of the same model and are connected to the same air circuit. Therefore, the thrust of the first cylinder 401 and the second cylinder 402 is the same.

[0064] refer to Figure 7 In some embodiments, each hinge assembly 410 includes: a connecting rod 411, a concave block 412, a bolt 413, and a drum-shaped block 414. (See reference...) Figure 11 The concave block 412 includes a base 412-1 and two lugs 412-2 extending vertically outward from the base 412-1. Each lug 412-2 has a first through hole 412-3 arranged laterally. Here, "laterally" refers to a direction parallel to the base 412-1. (Reference) Figure 8 and Figure 9 One end of the connecting rod 411 is a flat block 411-1, and a second through hole 411-2 is provided on the flat block 411-1. (Reference) Figure 10 A third through hole 414-1 is provided along the center of the upper and lower planes of the drum-shaped block 414. The drum-shaped block 414 is inserted into the second through hole 411-2 on the flat block 411-1, and then the flat block 411-1 of the connecting rod 411 is inserted into the gap between the two lugs 412-2, see... Figure 7 Then, bolts 413 are passed through the first through hole 412-3 and the third through hole 414-1 in sequence to connect the connecting rod 411 and the concave block 412 together, see... Figure 7 Since the outer surface of the drum-shaped block 414 is spherical and the inner surface of the third through hole 414-1 of the drum-shaped block 414 is also spherical, the drum-shaped block 414 can rotate smoothly within the third through hole 414-1. In other words, the concave block 412 can rotate relative to the connecting rod 411, so the left pressure plate assembly 420 connected to the concave block 412 can swing left and right in the horizontal plane, thereby allowing the two first contacts 405 provided on the left pressure plate assembly 420 to also swing left and right in the horizontal plane.

[0065] refer to Figure 12 , Figure 13 and Figure 14 In some embodiments, the left pressure plate assembly 420 includes: a first vertical plate 421, a second vertical plate 422, a first horizontal block 423, a second horizontal block 424, a first screw 425, a second screw 426, a first vertical guide rail 427, a first vertical slider 428, a first spring 429, and a second spring 429-1. Both the first vertical plate 421 and the second vertical plate 422 are parallel to the left mounting plate 404, with the first vertical plate 421 closer to the left mounting plate 404. The left end of the first horizontal block 423 is horizontally positioned at the front end of the first vertical plate 421, with its right side suspended. The first screw 425, after being fitted onto the first spring 429, passes vertically through the right end of the first horizontal block 423 and connects to the front end of the second vertical plate 422. The left end of the second horizontal block 424 is horizontally positioned at the rear end of the first vertical plate 421, with its right side suspended. After the second screw 426 is fitted onto the second spring 429-1, it passes vertically through the right end of the second horizontal block 424 and connects to the rear end of the second vertical plate 422. (Reference) Figure 14 The first vertical guide rail 427 is disposed on the front end of the first vertical plate 421 near the second vertical plate 422, and the first vertical slider 428 is disposed on the front end of the second vertical plate 422 near the first vertical plate 421. Two first contacts 405 (see...) Figure 4 These are respectively located at the front and rear ends of the lower part of the second vertical plate 422, and on the side closest to the wire frame. (Reference) Figure 12The base 412-1 of the concave plate is located in the gap between the first vertical plate 421 and the second vertical plate 422 and is detachably connected to the first vertical plate. It is understood that, due to the two first contacts 405 (see...), Figure 4 The first vertical block 405 is respectively located at the front and rear ends of the lower part of the second vertical plate 422 and abuts against one side of the mesh frame. The second vertical plate 422 can move up and down on the first vertical plate 421 via the first vertical slider 428 and the first vertical guide rail 427. As mentioned earlier, the concave block 412 can rotate relative to the connecting rod 411. Therefore, under the thrust of the first cylinder 401 and the second cylinder 402, the two first contacts 405 can swing left and right in the horizontal plane to adapt to... Figure 2 The left edge 03 of the mesh frame 0 is tilted to ensure that the two first contacts 405 can always rest against the left edge 03 of the mesh frame 0 in the horizontal plane. At the same time, the two first contacts 405 can also move up and down in the vertical direction to adapt to mesh frames 0 of different thicknesses.

[0066] refer to Figure 3 and Figure 5 In some embodiments, the right pressure plate assembly 50 includes: a third vertical plate 501, a fourth vertical plate 502, a third horizontal block 503, a fourth horizontal block 504, a second vertical guide rail 505, a second vertical slider 506, a third screw 507, a third spring 508, a third vertical guide rail 509, a third vertical slider 510, a fourth screw 511, and a fourth spring 512. (See reference) Figure 5 The third vertical plate 501 and the fourth vertical plate 502 are located side by side on the left side of the right mounting plate 513, and the third vertical plate 501 is mounted on the left side of the right mounting plate 513.

[0067] refer to Figure 5 The right ends of the third horizontal block 503 and the fourth horizontal block 504 are horizontally positioned at the front and rear ends of the upper part of the third vertical plate 501, respectively. The third screw 507, after being fitted into the third spring 508, vertically passes through the left end of the third horizontal block 503 and connects to the front end of the upper part of the fourth vertical plate 502. The fourth screw 511, after being fitted into the fourth spring 512, vertically passes through the fourth horizontal block 504 and connects to the rear end of the upper part of the fourth vertical plate 502. (Reference) Figure 15The second vertical guide rail 505 is located on the front end of the third vertical plate 501, near the fourth vertical plate 502. The second vertical slider 506 is located on the front end of the fourth vertical plate 502, near the second vertical plate. The third vertical guide rail 509 is located on the rear end of the third vertical plate 501, near the fourth vertical plate 502. The third vertical slider 510 is located on the rear end of the fourth vertical plate 502, near the second vertical plate. It can be understood that the fourth vertical plate 502 moves up and down along the second vertical guide rail 505 and the third vertical guide rail 509 via the second vertical slider 506 and the third vertical slider 510. Figure 5 The two second contacts 514 are fixed to the lower right side of the fourth vertical plate 502, so the second contacts 514 can also move up and down with the fourth vertical plate 502 to accommodate wire mesh frames of different thicknesses. The entire wire mesh frame 0 (see...) Figure 13 )exist Figure 4 Under the push of the first cylinder 401 and the second cylinder 402, it abuts against the two second contacts 514 to the right, so that the entire mesh frame 0 is clamped and fixed in the horizontal plane.

[0068] refer to Figure 13 and Figure 14 On the first vertical plate 421, a first square through hole 421-1 and a second square through hole 421-2 are also provided for the two sets of hinge assemblies mentioned above to pass through.

[0069] refer to Figure 4 In some embodiments, the left clamping component 40 further includes: a first bracket 430, a second bracket 431, a third cylinder 432 and a fourth cylinder 433. The first bracket 430 and the second bracket 431 are respectively disposed at the front and rear ends of the side wall of the left mounting plate 404 on the side closest to the mesh frame 0. The third cylinder 432 is mounted on the first bracket 430 and the fourth cylinder 434 is mounted on the second bracket 431.

[0070] refer to Figure 5 In some embodiments, Figure 3 The right clamping component 50 further includes: a third bracket 515, a fourth bracket 516, a fifth cylinder 517, and a sixth cylinder 518. The third bracket 515 and the fourth bracket 516 are respectively disposed on the left side wall of the right mounting plate 513. The fifth cylinder 517 is mounted on the third bracket 515, and the sixth cylinder 518 is mounted on the fourth bracket 516. When the third cylinder 432, the fourth cylinder 433, the fifth cylinder 517, and the sixth cylinder 518 apply a downward force, the force applied by the third cylinder 432 and the fourth cylinder 433 acts on... Figure 2 The forces applied by the fifth cylinder 517 and the sixth cylinder 518 act on the front and rear ends of the upper plane of the left border 02 of the grid frame 0. Figure 2The front and rear ends of the upper plane of the right frame 02 of the mesh frame 0 are fixed on the worktable 10 by the third cylinder 432, the fourth cylinder 433, the fifth cylinder 517, and the sixth cylinder 518 in the vertical direction (see...). Figure 3 ).

[0071] refer to Figures 16 to 18 In some embodiments, Figure 3 The front guide rail component 20 includes:

[0072] The front guide rail 201, first front slider 202, first front connecting block 203, front bracket 204, front pin 205, second front slider 206, and second front connecting block 207 are configured.
