Description

Technical Field

[0001] This utility model relates to the field of power, and in particular to a special screen printing template positioning fixture for use in conductive spray-coated hard-connected copper busbar products. Background Technology

[0002] Hard-connect copper busbars are widely used in power equipment, switchgear, and new energy battery systems due to their excellent conductivity, structural strength, and reliability. To facilitate installation, maintenance, identification, and meet safety regulations, the surface of the copper busbar is typically screen-printed with information such as model number, specifications, polarity, production batch, and safety warnings.

[0003] To enhance insulation, corrosion resistance, and aesthetics, rigid connection copper busbars typically undergo surface coating treatment (such as spraying insulating varnish) before or after screen printing. This coating process creates a smooth, thick layer on the copper busbar surface. When screen printing on the coated rigid connection copper busbar, the accuracy and consistency of the marking positions are extremely important. Incorrect or excessively large deviations in the marking positions not only affect the product's appearance but can also lead to installation errors, confusion, and even safety accidents.

[0004] Currently, the common practice is to rely entirely on the experience and visual inspection of the operators for positioning. These methods often have the following significant problems when dealing with hard-connected copper busbars that are complex in structure or varied in shape (especially those involving bends or irregular shapes): 1. Low positioning accuracy and extremely poor consistency: Human eye judgment is subject to subjective errors and visual fatigue, which causes the silkscreen position to fluctuate greatly between different workpieces and between the same batch of the same workpiece. In actual operation, the positioning deviation range can reach ±10mm, which is far from meeting the basic requirements of customers for the marking position (even if the customer does not explicitly specify a strict tolerance, the expected value is usually around ±2mm).

[0005] 2. Inefficient and prone to rework: Slow visual positioning severely impacts production efficiency. More seriously, inaccurate positioning leads to frequent screen printing errors. Once a mistake is made, the incorrect mark must be removed using solvents such as alcohol, and the screen printing process must be repeated. This rework process is not only time-consuming and labor-intensive, increasing costs, but can also adversely affect the surface of the coated layer (such as changes in gloss or slight dissolution).

[0006] 3. High dependence and unstable quality: Product quality is highly dependent on the skill level and concentration of the operators. Personnel changes or fluctuations in their condition will directly lead to unstable quality.

[0007] Therefore, there is an urgent need to customize a positioning fixture to replace purely manual positioning. Utility Model Content

[0008] In order to overcome the above-mentioned defects of the prior art, the present invention provides a positioning fixture for screen printing of hard-connected copper busbars, so as to solve the problems existing in the background art.

[0009] This utility model provides the following technical solution: a positioning fixture for screen printing of rigidly connected copper busbars, comprising: The positioning plate has two opposing surfaces; First positioning structure, multiple first positioning structures are arranged on one side of the positioning plate for positioning the product; The second positioning structure, multiple second positioning structures are detachably mounted on the positioning plate and are on the same side as the first positioning structure. The second positioning structure is located on the periphery of the first positioning structure. The multiple second positioning structures form a polygonal screen printing template limiting area with an opening to facilitate the positioning and placement of the screen printing template.

[0010] Preferably, the first positioning structure includes a circular positioning groove, a bolt, and a rectangular positioning groove, which together form multiple product limiting areas.

[0011] Preferably, the second positioning structure is a positioning bolt.

[0012] Preferably, the number of positioning bolts is four, and the four bolts are arranged in a trapezoidal structure to form a polygonal screen printing template limiting area with an opening.

[0013] Preferably, it also includes adjusting blocks, with multiple adjusting blocks movably mounted on the other side of the positioning plate. Each adjusting block is equipped with a positioning bolt, and the positioning bolt is assembled to one side of the positioning plate through the adjusting block.

[0014] Preferably, the positioning plate and the adjusting block are provided with suitable through holes for the positioning bolts to pass through.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a first positioning structure and a second positioning structure to position and fix the product to be screen-printed and the screen-printing template, respectively. This replaces the traditional positioning based on workers' experience and visual inspection, greatly improving the accuracy and consistency of screen printing. It not only eliminates the reliance on manual visual judgment but is also highly efficient and easy to use, significantly reducing operation time and ensuring the final quality of the product.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] This utility model provides a positioning fixture for screen printing of rigidly connected copper busbars, such as... Figure 1-5 As shown, it includes: positioning plate 1, first positioning structure 2, and second positioning structure 3.

[0024] Specifically, the positioning plate 1 has two opposing surfaces. Multiple first positioning structures 2 are disposed on one surface of the positioning plate 1 for positioning different types of products. Multiple second positioning structures 3 are also disposed on the positioning plate 1, on the same surface as the first positioning structures 2, and the second positioning structures 3 are located around the first positioning structures 2. The multiple second positioning structures 3 form a polygonal screen printing template limiting area with an opening to facilitate the positioning and placement of the screen printing template 7.

[0025] By setting the first positioning structure 2 and the second positioning structure 3 to position and fix the product to be screen printed and the screen printing template respectively, the traditional worker's experience and visual positioning is replaced, which greatly improves the accuracy (making the accuracy ≤±2mm) and consistency of screen printing. It not only gets rid of the dependence on human visual judgment, but is also efficient and easy to use, significantly reduces operation time, and ensures the final quality of the product.

[0026] During screen printing, the product is first placed in the corresponding first positioning structure 2 for positioning and fixing, and then the screen printing template 7 is inserted from the opening (i.e., one side of the second positioning structure 3 that is not set) so that the screen printing template 7 is consistent with the product to be screen printed.

[0027] Furthermore, the first positioning structure 2 includes a circular positioning groove 21, a bolt 22, and a rectangular positioning groove 23, which together form multiple product limiting areas. Multiple circular positioning grooves 21 form one limiting area for placing the first product 4, multiple bolts 22 form another limiting area for placing the second product 5, and multiple rectangular positioning grooves 23 form yet another limiting area for placing the third product 6, enabling simultaneous screen printing of multiple products and thus improving screen printing efficiency.

[0028] In this embodiment, the second positioning structure 3 is a positioning bolt 22. There are four positioning bolts 22, which are arranged in a trapezoidal structure to form a polygonal screen printing template 7 limiting area with an opening.

[0029] In this embodiment, an adjusting block 8 is also provided. Multiple adjusting blocks 8 are movably mounted on the other side of the positioning plate 1. Each adjusting block 8 is equipped with a positioning bolt 22, and the positioning bolt 22 is assembled to one side of the positioning plate 1 through the adjusting block 8. The positioning plate 1 and the adjusting blocks 8 are provided with matching through holes 9 for the positioning bolt 22 to pass through. The positioning bolt 22 not only realizes the positioning of the screen printing template 7, but also serves to connect and assemble the adjusting blocks 8.

[0030] The position of the positioning bolt 22 can be adjusted more flexibly by the four adjustment blocks 8 on the back of the positioning plate 1, thereby adjusting the position of the screen printing template 7. This allows for adjustments based on different sizes of screen printing templates 7, and other types of screen printing templates can also be adapted to this fixture, greatly improving its practicality.

[0031] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
