Description

Technical Field

[0001] This utility model relates to the field of photovoltaic backsheet glass production technology, specifically a screen printing stencil correction device. Background Technology

[0002] Currently, in the production process of photovoltaic enamel-coated glass in China, the screen printing plates used consist of two parts: the frame and the fabric. Due to the tension of the fabric, the frame may deform in the middle of its long side. This results in the blank space in the middle of the long side being either too large or too small, exceeding the tolerance. Although screen printing plate manufacturers have improved the frame profiles and increased the frame strength, they still cannot eliminate the elastic deformation of the frame. Some screen printing plates are forced to be taken off the machine during debugging due to unqualified blank space, while others are discarded due to poor blank space caused by changes in the fabric tension during use. This seriously affects product quality and the continuity of the production line, severely restricting the production line's capacity and normal production quality. Utility Model Content

[0003] To address the existing problems, this utility model provides a screen printing stencil correction device to solve the problem of excessive blank space caused by the deformation of the long side of the stencil frame due to the tension of the mesh fabric, as mentioned in the background art.

[0004] To address the existing problems, this utility model provides a screen printing stencil correction device, including a first clip detachably connected to the long side of the stencil frame, a second clip detachably connected to one side of the first clip and to the stencil support, and the first clip and the second clip being connected by an adjustment component.

[0005] Furthermore, the adjusting assembly includes a lead screw and two sets of nuts threaded onto the lead screw.

[0006] Furthermore, the side of the first card is rotatably connected to one end of the lead screw.

[0007] Furthermore, a slot is provided at the lower end of the second card.

[0008] Furthermore, the lead screw can be placed inside the slot.

[0009] Furthermore, each set of nuts consists of two nuts, which are clamped on both sides of the slot by a lead screw.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This screen printing screen correction device is installed on the screen holder and the long side of the screen frame during use. By twisting the nut, the screw can be pulled or pushed, which in turn pulls or pushes the first clamp, thereby adjusting the distance between the long side of the screen frame and the printing table (glass). This solves the problem of deformation of the long side of the screen frame caused by the tension of the screen fabric, thus ensuring that the blank size is qualified and overcoming the problem of excessive blank size in the middle of the long side of the screen frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 A screen printing screen correction device includes a first clip 2 detachably connected to the long side 1 of the screen frame, a second clip 3 detachably connected to one side of the first clip 2 and to the screen support 2, and the first clip 2 and the second clip 3 are connected by an adjustment component 4.

[0018] The adjusting assembly 4 includes a lead screw 401 and two sets of nuts 402 threaded onto the lead screw 401.

[0019] The side of the first clamp 2 is rotatably connected to one end of the lead screw 401.

[0020] The second card 3 has a slot 301 at its lower end.

[0021] The lead screw 401 can be placed inside the slot 301.

[0022] Each set of nuts 402 consists of two nuts, which are clamped on both sides of the slot 301 by the lead screw 401.

[0023] Working principle: During operation, firstly, the first clamp 2 is clamped onto the long side of the screen frame with its opening facing downwards. Then, the second clamp 3 is clamped onto the screen support 5 with its opening facing downwards, aligning the slot 301 with the lead screw 401. The second clamp 3 is then clamped onto the screen support 5. At this point, the nuts 402 located on both sides of the slot 301 are tightened. It should be noted that this screen printing screen correction device can be installed in several units on the screen support 5 and the long side 1 of the screen frame as needed. By twisting the nuts 402, the lead screw can be pulled or pushed, thereby pulling or pushing the first clamp 3. This allows the first clamp 2 to adjust the distance between the long side 1 of the screen frame and the printing table (glass), solving the problem of deformation of the long side 1 of the screen frame caused by the tension of the screen fabric, thus ensuring the acceptable blank size and overcoming the problem of excessive blank space in the middle of the long side 1 of the screen frame.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
