Description

Technical Field

[0001] This utility model relates to the field of solder paste dispensing technology, specifically to an anti-clogging syringe solder paste quantitative dispensing device. Background Technology

[0002] The syringe solder paste dispensing device is a device used for precise dispensing of solder paste. It is mainly used in the solder paste printing process of surface mount technology production lines in the electronics manufacturing industry. Its core function is to dispense high-viscosity solder paste into syringes or injectors according to a preset amount to ensure quantitative and uniform coating of solder paste in subsequent processes.

[0003] In conventional syringe solder paste dispensing devices, the connection between the storage tank and the syringe is extremely inconvenient. Typically, the storage tank and syringe need to be fixedly connected. This inconvenience not only increases operational complexity but also necessitates a secondary filling operation. During this secondary filling process, the solder paste inevitably comes into contact with the external environment, easily introducing dust, impurities, and other contaminants, severely affecting the purity of the solder paste. The needle replacement process also presents challenges. Conventional devices have complex needle installation structures, making replacement cumbersome and time-consuming, unable to achieve rapid replacement. In actual production, depending on different products and process requirements, it is often necessary to frequently change needles of different diameters to adapt to different coating needs. This cumbersome replacement process severely disrupts the production flow, reduces production efficiency, and increases production costs. Utility Model Content

[0031] 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.

[0032] To address the problems of inconvenient storage tank connections, the need for secondary filling, and the cumbersome syringe replacement in existing technologies, the following technical solution is provided. Please refer to [link / reference]. Figures 1-7 ;

[0033] A non-clogging syringe solder paste dispensing device includes a carrier component 1, on which a guide component 2 and a feeding component 3 are mounted. The guide component 2 includes a syringe 201, and a connecting component 4 is installed in the opening of the outer wall of the syringe 201. The connecting component 4 includes a feed tube 401 fixed in the opening of the outer wall of the syringe 201. The outer wall of the feed tube 401 has two equally spaced, circumferential grooves 403. The inner wall of each groove 403 has a retaining groove 404. The retaining groove 404 and the groove 403 are connected together. The L-shaped channel includes a storage tank 303, a connecting pipe 305 fixedly connected to the opening of the storage tank 303, symmetrically distributed support blocks 307 fixedly connected to the outer wall of the connecting pipe 305, a locking block 306 fixedly connected to one end of the support blocks 307 that is close to each other, the outer wall of the locking block 306 is in contact with the inner wall of the slide 403, the locking block 306 is adapted to the locking groove 404, and a sealing pipe 308 is fixedly connected to the inner wall of the opening of the connecting pipe 305, the outer wall of the sealing pipe 308 is in contact with the inner wall of the feed pipe 401.

[0034] The locking block 306 can slide along the inner wall of the slide groove 403, allowing the feed pipe 401 to fit against the opening of the connecting pipe 305, and moving the locking block 306 to the opening of the slot 404. Rotating the connecting pipe 305 can limit and fix the locking block 306 to the inner wall of the slot 404, connecting and fixing the feed pipe 401 and the connecting pipe 305. The sealing pipe 308 can block the gap between the feed pipe 401 and the connecting pipe 305, improving the sealing performance of the connection between the storage tank 303 and the syringe 201.

[0035] A dispensing assembly 5 is installed at the lower end of the syringe 201. The dispensing assembly 5 includes a fixed tube 501 fixed to the lower end of the syringe 201. The outer wall of the fixed tube 501 has several grooves 502 that are equidistantly arranged around it. A flip plate 503 is rotatably installed at the center of both ends of the grooves 502. A hook 504 is fixedly connected to the lower end of the flip plate 503. A needle 508 is provided below the fixed tube 501. The inner wall of the needle 508 is in contact with the outer wall of the fixed tube 501. The inner wall of the needle 508 has several hook grooves 505 that are equidistantly arranged around it. The hook grooves 505 correspond one-to-one with the hooks 504 and are compatible. The outer wall of the needle 508 has a second sliding groove 506. A magnetic ring 507 is slidably installed on the outer wall of the second sliding groove 506. The hooks 504 and the flip plate 503 are attracted to the magnetic ring 507.

[0036] By attaching the outer wall of the fixing tube 501 to the inner wall of the needle 508, the needle 508 can be fixed in place at the lower end of the fixing tube 501. The magnetic ring 507 can attract the lower end of the flip plate 503, causing the hook 504 to flip outward and insert into the hook groove 505, thereby connecting and fixing the needle 508 to the fixing tube 501. Pulling the magnetic ring 507 upward causes it to attract the upper outer wall of the flip plate 503, which in turn causes the hook 504 to flip into the groove 502, making it easy to remove the needle 508. This ensures the stability of the fixation while facilitating the disassembly of the needle 508, thus making it easy to replace the needle 508.

[0037] Please see Figure 3 The load-bearing component 1 includes a base 101, a support frame 102 is fixedly connected to the upper end of the base 101, and a support plate 103 is fixedly connected to the outer wall of the support frame 102; the base 101 can support the support frame 102 and the support plate 103, and the support frame 102 and the support plate 103 can bear the load of the equipment.

[0038] Please see Figure 4 A syringe 201 is fixedly connected to the front end of a support frame 102, and a protective pad 202 is fixedly connected to the outer wall of the syringe 201. The support frame 102 supports the syringe 201, and the protective pad 202 protects the outer wall of the syringe 201. An electric heating element 203 is installed on the inner wall of the protective pad 202, and a pneumatic pump 204 is fixedly connected to the upper opening of the syringe 201. The electric heating element 203 heats the outer wall of the syringe 201 to prevent the solder paste from solidifying and to ensure its fluidity. The pneumatic pump 204 pushes the solder paste downwards along the inner wall of the syringe 201. The air outlet of the pneumatic pump 204 is connected to a pipe at the upper opening of the syringe 201, and a suction valve 205 is fixedly connected to the lower outer wall of the syringe 201. The suction valve 205 controls the opening and closing of the lower opening of the syringe 201 and prevents solder paste from dripping.

[0039] Please see Figure 5 The feeding assembly 3 includes a fixed base 301 fixed to the support plate 103. The storage tank 303 is fixedly installed on the upper end of the fixed base 301 by a clamp 302. The clamp 302 can fix the storage tank 303 to the upper end of the fixed base 301, and the support plate 103 can fix the fixed base 301 to ensure the stability of the storage tank 303. A second air pressure pump 304 is fixedly connected to the upper end of the storage tank 303. The air inlet of the second air pressure pump 304 is connected to the interior of the storage tank 303 through a pipe. The second air pressure pump 304 can push the solder paste in the storage tank 303 to move, so that the storage tank 303 delivers solder paste to the syringe 201.

[0040] Please see Figure 6 and Figure 7A valve 402 is installed inside the feed pipe 401. A sealing ring is fixed at the joint between the feed pipe 401 and the connecting pipe 305. A sealing gasket is fixed to the outer wall of the sealing pipe 308. A sealing ring is fixed at the joint between the lower end of the fixing pipe 501 and the inner wall of the needle 508. The valve 402 can control the opening and closing of the connecting component 4 to facilitate quantitative delivery of solder paste. The sealing ring and sealing gasket can improve the sealing performance of the pipeline and prevent solder paste from overflowing and causing pollution.

[0041] Working principle: During operation, firstly, the second pneumatic pump 304 pushes the solder paste into the feed tube 401. After the solder paste is delivered to the appropriate volume, valve 402 is closed. Next, the first pneumatic pump 204 is started, causing it to push the solder paste along the syringe 201 into the needle 508. The needle 508 then guides the solder paste into the container to be dispensed. After dispensing is completed, the suction valve 205 is activated to draw any remaining solder paste back into the syringe 201, preventing dripping solder paste from contaminating the container.

[0042] During installation, when it is necessary to replace the needle 508, first push the magnetic ring 507 upward so that it adheres to the upper outer wall of the flip plate 503. This will cause the hook 504 to flip into the groove 502, allowing the needle 508 to be removed. Then, align the inner wall of the new needle 508 with the outer wall of the fixing tube 501, push the needle 508 upward so that its inner wall fits against the outer wall of the fixing tube 501, and then push the magnetic ring 507 downward. The magnetic ring 507 will adhere to the lower end of the flip plate 503, causing the hook 504 to flip outward so that it is inserted into the hook groove 505, thereby connecting and fixing the needle 508 and the fixing tube 501. When connecting the connecting pipe 305 and the feed pipe 401, the locking block 306 can slide along the inner wall of the slide groove 403, so that the feed pipe 401 and the opening of the connecting pipe 305 are in contact, and the locking block 306 is moved to the opening of the slot 404. Rotating the connecting pipe 305 can limit and fix the locking block 306 to the inner wall of the slot 404, thus connecting and fixing the feed pipe 401 and the connecting pipe 305. The sealing pipe 308 can block the gap between the feed pipe 401 and the connecting pipe 305.
