Description

Technical Field

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

[0002] In the screen printing process, for products requiring multi-color and multi-plane screen printing, existing technologies typically employ a multi-step operation using multiple independent screens, such as... Figure 1 The specific process for the battery product shown is as follows: 1. Place the product into the lower clamp of the screen printing equipment for positioning, ensuring the product does not move; 2. Install the first screen into the clamp of the screen printing equipment for positioning, and determine the screen insertion size through the first positioning hole of the product to ensure that the screen printing content is accurately positioned according to the drawing requirements (the upper and lower clamps of the screen printing equipment can move up and down 90° to overlap and open via a rotating shaft); 3. Pour the corresponding color ink into the first screen and use a squeegee to scrape the ink twice with appropriate force to fully screen print the ink onto the product surface (when screen printing black text, use tape to cover the B+ that needs to be screen printed in red text; similarly, when screen printing red text, use tape to cover the B-, MSD, and COM that need to be screen printed in black text; after each screen printing is completed, wait for the previous screen printing to be completely dry before the next screen printing, which is expected to take about half an hour); 4. Similarly, use the second screen to screen print the lower positioning L of the step in the same way; 5. After completing the screen printing of all colors and planes in sequence, transfer the product to the next process.

[0003] However, the aforementioned existing technologies have significant drawbacks: First, multi-color, multi-plane screen printing requires multiple repetitions, and each operation requires waiting for the previous ink to dry completely, resulting in a significant increase in production time and low efficiency. Second, during multiple screen printing processes, environmental factors such as climate and temperature at different times can easily lead to differences in ink drying speed, resulting in significant color differences and affecting product quality. Third, each screen printing requires repositioning of the screen plate, and repeated positioning can easily cause deviations in the size of the screen-printed content, reducing screen printing accuracy. Fourth, the production and maintenance of multiple independent screen plates require additional material costs, increasing production expenses. Utility Model Content

[0004] The main purpose of this invention is to provide a high-precision, high-efficiency, and low-cost screen printing stencil to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides a high-precision, high-efficiency, and low-cost screen printing stencil, comprising a stencil body, which is an integrated structure with multiple grid units on it. The area of ​​each grid unit corresponds to the area to be screen printed on the product, and the planar position of each grid unit corresponds to the planar position of the area to be screen printed on the product. An isolation structure is provided between adjacent grid units. The stencil body also has a positioning structure that is adapted to a first positioning hole on the product.

[0006] Furthermore, the screen body includes a frame and a screen printing mesh fabric disposed on the frame.

[0007] Furthermore, the frame is made of wood or aluminum alloy.

[0008] Furthermore, the number and position of the grid cells are set according to the color and position distribution of the content to be screen-printed on the product.

[0009] Furthermore, the isolation structure is an integrally formed raised frame on the screen body, and the height of the raised frame is not less than the maximum ink accumulation height during the screen printing process.

[0010] Furthermore, the positioning structure is a second positioning hole formed on the mesh plate body, and the number and position of the second positioning hole correspond to the number and position of the first positioning hole on the product.

[0011] This utility model has the following beneficial effects: 1. This utility model achieves one-time screen printing of multiple colors and multiple planes through the integrated screen plate and multi-grid unit design, eliminating the need for multiple screen plate replacements and waiting for ink to dry, thus greatly shortening production time; 2. This utility model only requires one positioning to complete the screen printing of all contents, avoiding the size deviation caused by multiple positioning in the traditional method; 3. Environmental factors are stable during a single screen printing process, and there is no need to layer ink multiple times, which effectively avoids the color difference problem caused by multiple screen printing and improves the consistency of product appearance. 4. The integrated stencil replaces the traditional multiple stencils, reducing the material and maintenance costs of stencil production, while shortening the production cycle and reducing labor costs.

[0018] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0019] like Figure 4-5 As shown, this utility model provides a high-precision, high-efficiency, and low-cost screen printing stencil, including a stencil body 4. The stencil body 4 is made of a composite of a screen printing mesh 42 and a frame 41, wherein the frame 41 can be made of wood or aluminum alloy. The stencil body 4 is an integrated structure with multiple grid units 43. The number and position of the grid units 43 are set according to the color and position distribution of the content to be screen printed on the product 1. The area of ​​each grid unit 43 corresponds to the area to be screen printed on the product 1, and the planar position of each grid unit 43 corresponds to the planar position of the area to be screen printed on the product 1. An isolation structure is provided between adjacent grid units 43. The isolation structure is a raised frame 45 integrally formed on the stencil body 4, and the height of the raised frame 45 is not less than the maximum ink accumulation height during the screen printing process. The stencil body 4 also has a positioning structure, which is adapted to the first positioning hole 11 on the product 1. The positioning structure is a second positioning hole 44 opened on the mesh plate body, and the number and position of the second positioning hole 44 correspond to the number and position of the first positioning hole 11 on the product 1.

[0020] The following example uses a screen printing stencil for battery products: A high-precision, high-efficiency, and low-cost screen printing stencil includes a stencil body 4, which is an integrated structure made of a screen printing-specific mesh fabric 42 and an aluminum alloy frame 41, ensuring structural strength while reducing the weight of the stencil. The stencil body 4 has three grid units 43, corresponding to areas on product 1 where black “B-”, “MSD”, and “COM” need to be screen printed, red “B+” needs to be screen printed, and black “L” needs to be screen printed.

[0021] A raised frame 45 is provided between adjacent grid units 43 as an isolation structure. The height of the raised frame 45 is higher than the maximum ink accumulation height during screen printing, which can effectively prevent black and red ink from mixing. Two second positioning holes 44 are opened on the screen body 4 as positioning structures. The diameter and spacing of the second positioning holes 44 are consistent with the first positioning holes 11 on the product 1, so as to achieve precise alignment between the screen and the product.

[0022] The specific screen printing process is as follows: 1. Place product 1 into the fixing clamp of the screen printing equipment to ensure that the product does not move; 2. Mount the screen printing stencil into the fixing clamp on the screen printing equipment. Align the second positioning hole 44 with the first positioning hole 11 of product 1 to determine the stencil mounting size and ensure that the screen printing content is accurately positioned according to the drawing requirements (the upper and lower fixing clamps of the screen printing equipment can move up and down 90° to overlap and open via a pivot). 3. Pour an appropriate amount of color ink into each of the grid cells 43 as required, and use a squeegee to scrape the ink twice with appropriate force to ensure that the ink is fully screen-printed onto the product surface; 4. Once the product screen printing is complete, remove it and proceed to the next production process.
