[0002] The screen printing stencil plays a key role in the solder paste printer. Its main function is to accurately transfer solder paste to the pads of the printed circuit board (PCB). This process is part of SMT (Surface Mount Technology) and involves delicate craftsmanship in electronic manufacturing.

[0003] After solder paste printing, solder paste will remain on the surface of the screen printing steel mesh, and cleaning equipment needs to be used regularly to clean the residual solder paste on the screen printing steel mesh. Existing cleaning equipment includes a reel for releasing clean cleaning paper and a reel for recycling dirty cleaning paper. The cleaning paper is used to wipe the screen printing steel mesh to clean the residual solder paste.

[0004] Cleaning paper is a consumable and will be used up quickly. Moreover, it cannot be washed and reused, which is neither environmentally friendly nor conducive to cost control.

[0005] Therefore, it is necessary to improve the existing cleaning equipment to solve the problem of high production cost caused by the rapid consumption of consumables.

[0006] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art.

[0046] The utility model provides a steel mesh cleaning device, which is suitable for the application scenario of cleaning the silk screen steel mesh, and can effectively solve the problem that the consumables of the existing cleaning equipment are consumed quickly, resulting in high production costs.

[0047] See also Figure 1~Figure 3 The steel mesh cleaning device provided in this embodiment includes a driving platform 1, a scraper plate 2 installed on the driving platform 1 and used to scrape off debris on the screen printing steel mesh 100, and a glue removal component 3 for removing debris on the scraper plate 2.

[0048] The stencil cleaning device provided in this embodiment, when the screen printing stencil 100 needs to be cleaned, the driving platform 1 drives the squeegee plate 2 to move upward, so that the squeegee plate 2 presses against the bottom surface of the screen printing stencil 100 upward, and then the driving platform 1 drives the squeegee plate 2 to reciprocate in the horizontal direction, so that the squeegee plate 2 repeatedly scrapes the bottom of the screen printing stencil 100, thereby scraping off the solder paste and other debris on the bottom surface of the screen printing stencil 100;

[0049] After the squeegee board 2 performs the squeegee operation on the screen printing steel mesh 100 for many times, sundries such as solder paste are likely to remain on the squeegee board 2 . In this case, the sundries on the squeegee board 2 can be removed by using the glue removal component 3 .

[0050] The steel mesh cleaning device provided in this embodiment has a scraper plate 2 that can be used repeatedly and wears slowly, thereby effectively solving the problem of high production costs caused by the rapid consumption of consumables in existing cleaning equipment.

[0051] Optionally, the driving platform 1 includes a platform base plate 101 , a platform horizontal linear driving mechanism 102 , a platform vertical linear driving mechanism 103 , and a lifting bracket 104 .

[0052] The driving end of the platform horizontal linear driving mechanism 102 is connected to the platform bottom plate 101, and is used to drive the platform bottom plate 101 to reciprocate perpendicular to the length direction of the scraper plate 2. The platform vertical linear driving mechanism 103 is installed on the platform bottom plate 101. The lifting bracket 104 is driven by the platform vertical linear driving mechanism 103 to move up and down relative to the platform bottom plate 101; wherein the scraper plate 2 is installed on the lifting bracket 104.

[0053] When the silk screen steel mesh 100 needs to be cleaned, the platform vertical linear drive mechanism 103 drives the lifting bracket 104 to drive the scraper plate 2 to move upward to against the bottom surface of the silk screen steel mesh 100; the platform horizontal linear drive mechanism 102 drives the platform bottom plate 101 to reciprocate in the horizontal direction, thereby repeatedly scraping glue on the bottom surface of the silk screen steel mesh 100.

[0054] Optionally, the top surface of the lifting bracket 104 is provided with an insertion plate groove for inserting the lower part of the scraper plate 2. The scraper plate 2 can be detachably installed in the insertion plate groove by magnetic adsorption or fastening with fasteners. When the glue removal component 3 is difficult to clean the debris on the scraper plate 2, the scraper plate 2 can be removed and cleaned.

[0055] In this embodiment, the driving platform 1 further includes a connecting plate 105 , which is fixed to the driving end of the platform vertical linear driving mechanism 103 , and the connecting plate 105 is rotatably connected to the lifting bracket 104 via a horizontal rotating shaft 106 .

[0056] The left and right ends of the lifting bracket 104 are rotatably connected to a connecting plate 105 through a horizontal rotating shaft 106, and each connecting plate 105 is correspondingly provided with a platform vertical linear drive mechanism 103. When the thickness of the left and right ends of the debris at the bottom of the silk screen steel mesh 100 is inconsistent (for example, the left is thick and the right is thin), in order to make the lifting bracket 104 as close to the silk screen steel mesh 100 as possible, the extension strokes of the left and right platform vertical linear drive mechanisms 103 are also inconsistent, so the lifting bracket 104 will also present a tilted state (for example, the left is low and the right is high). The setting of the horizontal rotating shaft 106 is conducive to the lifting bracket 104 being able to adapt to the uneven thickness of the debris at the bottom of the silk screen steel mesh 100 and present a tilted state.

[0057] Optionally, the glue removal component 3 includes a glue removal wheel 301 , a glue removal rotation drive mechanism 302 , a transposition rotation drive mechanism 303 , a glue removal vertical linear drive mechanism 304 , and a glue removal horizontal linear drive mechanism 305 .

[0058] The driving end of the degumming rotary drive mechanism 302 is in transmission connection with the degumming wheel 301, and is used to drive the degumming wheel 301 to rotate around a horizontal axis. The driving end of the transposition rotary drive mechanism 303 is connected to the degumming rotary drive mechanism 302, and is used to drive the degumming wheel 301 to rotate around a vertical axis; wherein the degumming wheel 301 has a degumming state in which it is driven forward by the transposition rotary drive mechanism 303 to rotate to the top of the scraper 2, and has an avoidance state in which it is driven reversely by the transposition rotary drive mechanism 303 to rotate to the side of the scraper 2.

[0059] The driving end of the glue removal vertical linear drive mechanism 304 is connected to the transposition rotation drive mechanism 303, and is used to drive the glue removal wheel 301 to move up and down. The driving end of the glue removal horizontal linear drive mechanism 305 is connected to the glue removal vertical linear drive mechanism 304, and is used to drive the glue removal wheel 301 to reciprocate along the length direction of the scraper 2.

[0060] When the scraper 2 needs to be desizing, the process is as follows:

[0061] ① The transposition rotation driving mechanism 303 drives the rubber removal wheel 301 to rotate around the vertical axis to the top of the rubber scraper 2;

[0062] ② The glue removal vertical linear driving mechanism 304 drives the glue removal wheel 301 to move downward until it abuts against the top surface of the scraper plate 2;

[0063] ③ The glue removal horizontal linear driving mechanism 305 drives the glue removal wheel 301 to reciprocate along the length direction of the scraper plate 2, thereby transferring the debris on the scraper plate 2 to the glue removal wheel 301;

[0064] ④ After the degumming wheel 301 has repeatedly degummed the scraper 2 at the same position, the degumming rotary drive mechanism 302 drives the degumming wheel 301 to rotate around the horizontal rotation axis 106 by a preset angle (e.g., 30° or 45°, etc.), so that the degumming wheel 301 can degummed the scraper 2 at the position where the degumming operation was not performed next time;

[0065] ⑤ After the glue removal operation is completed, the repositioning rotation drive mechanism 303 drives the glue removal wheel 301 to rotate in the opposite direction around the vertical axis to the side position of the scraper plate 2, so that the glue removal wheel 301 leaves the area directly above the scraper plate 2 to avoid affecting the next glue scraping operation of the scraper plate 2 on the silk screen steel mesh 100.

[0066] In this embodiment, the glue removal wheel 301 can be a washable flexible wheel such as a silicone wheel or a rubber wheel. When the flexible wheel is driven by the glue removal rotating drive mechanism 302 to rotate a full circle, it can be disassembled for manual cleaning and reused after cleaning. In some other embodiments, the glue removal wheel 301 can also be a cotton wheel. When the cotton wheel is driven by the glue removal rotating drive mechanism 302 to rotate a full circle, it can be replaced with a new cotton wheel;

[0067] It should be noted that the linear drive mechanism mentioned in the present invention can be a cylinder, a hydraulic cylinder, an electric cylinder or a motor screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, a brushless motor, or a rotary cylinder, etc. The present invention does not limit the specific structural forms of the linear drive mechanism and the rotary drive mechanism.

[0068] In summary, the steel mesh cleaning device provided in this embodiment has the following advantages:

[0069] ① Use the scraper 2 to clean the screen printing steel mesh 100. The scraper 2 can be used repeatedly and wears slowly, so it can effectively solve the problem of high production cost caused by the fast consumption of consumables of existing cleaning equipment;

[0070] ② The glue removal component 3 can be intelligently controlled to regularly clean the scraper plate 2, so that the scraper plate 2 can be kept clean to clean the screen printing steel mesh 100;

[0071] ③ The scraper can be detachably installed in the slot of the plug-in board by means of magnetic adsorption or fastening with fasteners. When the glue removal component 3 is difficult to clean the debris on the scraper board 2, the scraper board 2 can be removed and cleaned;

[0072] ④ The connecting plate 105 is rotatably connected to the lifting bracket 104 via the horizontal rotating shaft 106, which is beneficial for the lifting bracket 104 to adapt to the uneven thickness of debris at the bottom of the silk screen steel mesh 100 and present an inclined state.

[0073] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
