Description

Technical Field

[0001] This utility model belongs to the field of screen printing technology, specifically relating to a screen printing clamping device. Background Technology

[0002] Screen printing refers to the process of creating a screen printing plate with images and text using a photosensitive method, using a screen as the printing base. Screen printing consists of five main elements: the printing screen, the squeegee, the ink, the printing table, and the substrate. It utilizes the basic principle that ink can pass through the mesh openings of the screen where the image is visible, while ink cannot pass through the openings where there is no image.

[0003] Printing screens generally require photochemical exposure. During exposure, there are many different sizes and specifications of printing screens, and the patterns exposed on the printing screens are also diverse. This results in frequent changes of printing screens and screen fixtures during regular exposure. Moreover, each exposure can only be performed on a single printing screen, which seriously affects production efficiency.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0036] Example 1

[0037] Reference Figures 1 to 6As shown, this embodiment provides a printing screen clamping device, which includes a plurality of clamping components arranged along a first direction, which is a vertical direction. The clamping components include a first substrate 1, a second substrate 2, a first clamp 3, a second clamp 4, a first positioning member 5, a second positioning member 6, and a driving unit.

[0038] Specifically, in this embodiment, the first substrate 1 and the second substrate 2 are arranged opposite to each other along a first direction. The first clamp 3 is fixedly mounted on the first substrate 1, and the second clamp 4 is fixedly mounted on the second substrate 2. The first positioning member 5 and the second positioning member 6 are arranged opposite to each other along a second direction. Both the first positioning member 5 and the second positioning member 6 are fixedly mounted on the first substrate 1. The first positioning member 5 is located between the first clamp 3 and the second clamp 4, and the second positioning member 6 is also located between the first clamp 3 and the second clamp 4. The driving unit is connected to the second substrate 2. The driving unit can drive the second substrate 2 away from and closer to the first substrate 1, changing the distance between the first clamp 3 and the second clamp 4, so that the first clamp 3 and the second clamp 4 can clamp and fix the printing screen 15 together.

[0039] Reference Figure 4 As shown, in this embodiment, the first clamp 3 is constructed as an L-shaped structure or an approximately L-shaped structure. The first clamp 3 is disposed on the first substrate 1 along the exposure direction 16, and the first clamp 3 and the first substrate 1 surround to form a first receiving groove for accommodating the printing screen 15.

[0040] Specifically, the first clamp 3 includes a horizontally extending first plate 31 and a vertically upward extending second plate 32. The top surface of the first plate 31 forms a first abutting surface 301 facing the second substrate 2 and the second clamp 4. The first abutting surface 301 is used to abut against the printing screen 15 from the bottom to the circumferential outer surface of the printing screen 15, that is, to support the printing screen 15 from the bottom and restrict the printing screen 15 from moving downward. The second plate 32 forms a second abutting surface 302 on the side near the first substrate 1. The second abutting surface 302 is used to abut against the printing screen 15 from the exposure direction 16 and restrict the printing screen 15 from moving along the exposure direction 16.

[0041] The first abutting surface 301 and the second abutting surface 302 can be set as a plane or a curved surface protruding towards the printing screen 15.

[0042] Reference Figure 1 and Figure 2 As shown, in this embodiment, multiple first clamps 3 are provided, and the multiple first clamps 3 on the first substrate 1 are distributed at intervals.

[0043] Furthermore, in this embodiment, the printing screen clamping device also includes a first driving member 7 that cooperates with the first clamp 3. The first driving member 7 is mounted on the first substrate 1 and is used to drive the printing screen 15 to move toward the second abutment surface 302, so that the printing screen 15 is in close contact with the second abutment surface 302.

[0044] The first driving component 7 includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, and electric cylinders.

[0045] Similarly, refer to Figure 5 As shown, the second clamp 4 in this embodiment has a similar structure to the first clamp 3. The second clamp 4 is disposed on the second substrate 2 along the exposure direction 16. The second clamp 4 is also constructed as an L-shaped structure or an approximately L-shaped structure. The second clamp 4 and the second substrate 2 surround to form a second receiving groove for accommodating the printing screen 15.

[0046] Specifically, the second clamp 4 includes a horizontally extending third plate 41 and a vertically upward extending fourth plate 42. The bottom surface of the third plate 41 forms a third abutment surface 401 facing the first substrate 1 and the first clamp 3. The third abutment surface 401 is used to abut against the printing screen 15 from the top to the circumferential outer surface of the printing screen 15, restricting the printing screen 15 from moving upward. The fourth plate 42 forms a fourth abutment surface 402 on the side near the second substrate 2. The fourth abutment surface 402 is used to abut against the printing screen 15 from the exposure direction 16, restricting the printing screen 15 from moving along the exposure direction 16.

[0047] The third abutment surface 401 and the fourth abutment surface 402 can be set as a plane or a curved surface protruding towards the printing screen 15.

[0048] Reference Figure 1 and Figure 2 As shown, in this embodiment, multiple second clamps 4 are provided, and the multiple second clamps 4 on the second substrate 2 are distributed at intervals.

[0049] Furthermore, in this embodiment, the printing screen clamping device also includes a second driving member 8 that cooperates with the second clamp 4. The second driving member 8 is mounted on the second substrate 2 and is used to drive the printing screen 15 to move toward the fourth abutment surface 402, so that the printing screen 15 is in close contact with the fourth abutment surface 402.

[0050] The second driving component 8 includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, and electric cylinders.

[0051] Reference Figure 1 , Figure 2 and Figure 6 As shown, the first positioning member 5 includes a first positioning surface 501 facing the second positioning member 6, the first positioning surface 501 being used to abut against the circumferential outer surface of the printing screen 15.

[0052] Similarly, the second positioning member 6 includes a second positioning surface 601 facing the first positioning member 5, the second positioning surface 601 being used to abut against the circumferential outer surface of the printing screen 15.

[0053] The first positioning surface 501 and the second positioning surface 601 can be set as a plane or a curved surface protruding towards the printing screen 15.

[0054] In practical applications, the operator can place the printing screen 15 on the first clamp 3, and then move the printing screen 15 horizontally so that one side of the printing screen 15 abuts against the first positioning surface 501 or the second positioning surface 601. The first positioning surface 501 or the second positioning surface 601 is used to position the printing screen in the second direction. Then the second clamp 4 is lowered, and the printing screen 15 is held by the first clamp 3 and the second clamp 4.

[0055] Alternatively, when the size of the printing screen 15 in the second direction is equal to the distance between the first positioning surface 501 and the second positioning surface 601 in the second direction, the printing screen 15 can simultaneously adhere to the first positioning surface 501 and the second positioning surface 601.

[0056] Reference Figure 1 and Figure 2 As shown, the drive unit includes a guide rail 10, a first moving member 9 slidably connected to the guide rail 10 and connected to the second substrate 2, and a drive mechanism for driving the first moving member 9 to move along the guide rail 10.

[0057] Furthermore, the drive mechanism includes a second movable member 11 connected to the second base plate 2, a lead screw nut mounted on the second movable member 11, a lead screw 12 passing through the lead screw nut, and a motor 13 driving the lead screw 12 to rotate. Two guide rails 10 are provided, located on both sides of the lead screw 12.

[0058] Furthermore, the guide rail 10 is provided with two limiting members 14 located on both sides of the first moving member 9. The two limiting members 14 are used to limit the movement range of the first moving member 9 and restrict the first moving member 9 between the two limiting members 14.

[0059] Reference Figure 1 and Figure 2 As shown, the clamping assembly includes a first clamping assembly and a second clamping assembly arranged along a first direction. The second clamping assembly is located on top of the first clamping assembly. The first clamping assembly and the second clamping assembly share the same guide rail 10. The first substrate 1 of the second clamping assembly is mounted on the guide rail 10. A limiting structure is provided on the guide rail 10 to restrict the movement of the first substrate 1 along the guide rail 10.
