Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, and in particular to a glue-wiping structure for a dispensing valve of a dispensing machine. Background Technology

[0002] A dispensing machine, also known as a glue applicator or glue applicator, is an automated device used to apply liquid substances such as glue, paint, and solder paste to the surface or interior of electronic components, mechanical parts, and other products in a quantitative and targeted manner. The wiping structure of the dispensing valve in a dispensing machine is a key component for removing residual fluid from the valve orifice and ensuring dispensing accuracy. Dispensing machines are usually equipped with motor-driven winding and unwinding rollers. The winding and unwinding rollers wind up the wiping tape, which is then guided into a V-shape by an array of vertical rods. A cylinder-driven clamping structure presses the wiping tape against the opposing clamping point of the dispensing valve needle, which repeatedly descends to wipe it.

[0003] A glue-wiping device, disclosed in CN221016869U, includes a base, a support column, and a clamping component. This glue-wiping device can flatten the glue-wiping tape by abutting it through the flat part in the peripheral wall of the support column, thus avoiding wrinkles during the unwinding and conveying of the glue-wiping tape and having the advantage of good glue removal effect on the dripping head.

[0004] Currently, the adhesive wiping device used in dispensing machines uses two sets of clamping members with clamping strips in their clamping grooves to support the adhesive tape in contact with the dispensing valve needle during the adhesive wiping operation. However, this structure of clamping the adhesive tape to contact the dispensing valve needle is relatively simple, and its clamping and containment of the adhesive tape after clamping is not good, resulting in limited adhesive wiping effect of the dispensing valve needle at the adhesive tape. In addition, the adhesive tape clamped by the clamping members is prone to wrinkles caused by uneven local stress, which affects the subsequent neat winding of the adhesive. Therefore, we propose an adhesive wiping structure for the dispensing valve of a dispensing machine. Utility Model Content

[0005] The main objective of this invention is to provide a wiping structure for a dispensing valve in a dispensing machine. By improving the clamping components A and B at the base of the existing wiping device, a flat clamping mechanism is installed. The V-shaped pressure groove block at clamping component A, in conjunction with the V-shaped connecting block at clamping component B, clamps the wiping tape close to the dispensing valve needle. Simultaneously, the convex rubber plate at the V-shaped pressure groove, in conjunction with the T-shaped rubber spring within the V-shaped connecting groove, works together to abut the wiping tape against the dispensing valve needle, effectively improving the clamping and containment of the wiping tape against the needle. This ensures full contact between the wiping tape and the needle surface, significantly enhancing the wiping cleanliness and effectively solving the problem of limited wiping effect in existing wiping structures. Furthermore, the flat pressure plates and flat connecting edge plates at clamping components A and B can flatten the wiping tape after wiping, preventing wrinkles from forming and affecting the regularity of the subsequent winding process. This effectively solves the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A glue-wiping structure for a dispensing valve of a dispensing machine includes a base, a glue-wiping tape, clamping components A and B. The glue-wiping tape is wound around the top of the base, and clamping components A and B, which are connected to a bottom cylinder, are symmetrically installed on both sides of the V-shaped distribution body of the glue-wiping tape. The structure also includes a flattening mechanism, which comprises a connecting block, a flat pressure plate, a T-shaped glue spring post, a raised glue plate, and a flat edge plate. The opposing surfaces of clamping components A and B are... A flat pressure plate and a connecting block are welded on respectively, and a V-shaped groove for mounting a V-shaped pressure block is opened on the surface of the connecting block. The V-shaped pressure block is welded to the surface of the flat pressure plate in the center. A T-shaped rubber elastic column is vertically mounted in the cavity of the V-shaped groove, and flat connecting side plates are symmetrically raised on the surface of the connecting block on both sides of the V-shaped groove. A V-shaped pressure groove is opened at the head of the V-shaped pressure block, and a raised strip rubber plate is symmetrically bonded to the inner wall of the V-shaped pressure groove of the V-shaped pressure block.

[0007] Furthermore, a T-shaped inner groove is centrally formed in the cavity of the V-shaped groove, extending into the connector block, and a T-shaped elastic post is inserted and bonded into the cavity of the T-shaped inner groove, with the cylindrical body of the T-shaped elastic post protruding into the V-shaped groove. By adopting the above technical solution, the T-shaped adhesive spring can be fixed in the T-shaped inner groove and then cooperate with the V-shaped receiving groove to receive the adhesive tape contacting the dispensing valve needle.

[0008] Furthermore, the inner wall of the V-shaped groove of the V-shaped groove block is symmetrically provided with an inner fixed groove, and a raised strip adhesive plate is embedded in the inner fixed groove, the flat body of the raised strip adhesive plate protruding into the V-shaped groove. By adopting the above technical solution, the convex strip rubber plate can be bonded and fixed in the inner groove, thereby cooperating with the V-shaped pressure groove block to receive the contact valve needle of the adhesive tape.

[0009] Furthermore, the flat pressure plate and the flat joint edge plate are provided with rounded head plates at both ends; By adopting the above technical solution, the round head plate of the flat pressure plate and the flat joint edge plate can be easily wiped with adhesive tape.

[0010] Furthermore, the V-shaped groove opening width of the V-shaped groove block is greater than the cylindrical diameter of the T-shaped rubber elastic column; By adopting the above technical solution, the cylindrical body of the T-shaped rubber elastic column can be pressed into the V-shaped groove of the V-shaped pressure block.

[0011] Furthermore, the bottom ends of the blocks of clamping member A and clamping member B are fixed with perforated blocks that extend into the base, and the blocks with perforated blocks are installed with the clamping claws of the clamping cylinder in the base by bolts. By adopting the above technical solution, the perforated blocks of clamping component A and clamping component B can be inserted into the base and installed with bolts and gripper cylinders, making it convenient to be driven in opposite directions.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention improves the clamping mechanism of clamping components A and B at the base of the existing dispensing valve wiping device by setting up a clamping flattening mechanism. The V-shaped pressure groove block at clamping component A, together with the connecting block with a V-shaped groove at clamping component B, can clamp the wiping tape close to the dispensing valve needle. At the same time, the convex rubber plate at the V-shaped pressure groove and the T-shaped rubber elastic post in the V-shaped connecting groove cooperate to abut the wiping tape against the dispensing valve needle, effectively improving the clamping and containment of the wiping tape on the dispensing valve needle, so that the wiping tape and the surface of the dispensing valve needle can fully contact each other, significantly enhancing the wiping cleanliness of the wiping tape, and effectively solving the problem of limited wiping effect of the existing wiping structure. Furthermore, the flat pressure plate and flat joint plate at clamping parts A and B can flatten the adhesive tape after applying the adhesive, preventing wrinkles from forming on the adhesive tape and affecting the regularity of the subsequent winding process.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-3As shown, a glue-wiping structure for a dispensing valve of a dispensing machine includes a base 1, a glue-wiping tape 2, clamping components A3 and B4. The glue-wiping tape 2 is wound around the top of the base 1, and clamping components A3 and B4, which are connected to the bottom cylinder, are symmetrically installed on both sides of the V-shaped distribution body of the glue-wiping tape 2. The structure also includes a flat clamping mechanism 5, which includes a connecting block 6, a flat pressure plate 9, a T-shaped glue spring post 11, a raised glue plate 13, and a flat edge plate 14. The clamping components A3 and B4 are positioned opposite each other. A flat pressure plate 9 and a connecting block 6 are welded to the plate surface respectively. The surface of the connecting block 6 is provided with a V-shaped groove 7 for mounting a V-shaped pressure block 8. The V-shaped pressure block 8 is welded to the surface of the flat pressure plate 9 in the center. A T-shaped rubber elastic column 11 is vertically mounted in the groove cavity of the V-shaped groove 7. Flat connecting edge plates 14 are symmetrically raised on the surfaces of the connecting blocks 6 on both sides of the V-shaped groove 7. A V-shaped pressure groove is provided at the head of the V-shaped pressure block 8. Raised strip rubber plates 13 are symmetrically bonded to the inner wall of the V-shaped pressure groove of the V-shaped pressure block 8.

[0019] The V-shaped groove 7 has a T-shaped inner groove 10 that extends into the connector block 6, and a T-shaped elastic post 11 is inserted and bonded into the groove of the T-shaped inner groove 10. The cylindrical part of the T-shaped elastic post 11 protrudes into the V-shaped groove 7. By adopting the above technical solution, the T-shaped adhesive spring 11 can be fixed in the T-shaped inner groove 10 after being fixed and glued, and then cooperate with the V-shaped receiving groove 7 to receive the adhesive tape 2 to contact the glue valve needle.

[0020] The inner wall of the V-shaped groove of the V-shaped groove block 8 is symmetrically provided with an inner fixed groove 12, and a raised strip adhesive plate 13 is embedded in the inner fixed groove 12. The flat plate of the raised strip adhesive plate 13 protrudes into the V-shaped groove. By adopting the above technical solution, the convex strip rubber plate 13 can be bonded and fixed in the inner groove 12 for fixation, thereby cooperating with the V-shaped pressure groove block 8 to receive the contact nozzle of the adhesive tape 2.

[0021] Among them, the flat pressure plate 9 and the flat joint plate 14 are provided with round head plates at both ends; By adopting the above technical solution, the round head plate of the flat pressure plate 9 and the flat joint plate 14 can be easily passed through the adhesive tape 2.

[0022] The V-shaped groove opening width of the V-shaped groove block 8 is greater than the cylindrical diameter of the T-shaped rubber elastic column 11. By adopting the above technical solution, the cylindrical T-shaped rubber elastic column 11 can be pressed into the V-shaped groove of the V-shaped pressing block 8.

[0023] Among them, the bottom end of the clamping component A3 and the clamping component B4 is fixed with a perforated block extending into the base 1, and the perforated block is installed with the clamping cylinder clamp in the base 1 by bolts. By adopting the above technical solution, the perforated blocks of clamping component A3 and clamping component B4 can be inserted into the base 1 and installed with bolts and gripper cylinders, making it convenient to be driven in opposite directions.

[0024] It should be noted that this utility model is a glue-wiping structure for a dispensing valve of a dispensing machine. It improves the existing dispensing valve glue-wiping device by adding a clamping and flattening mechanism 5 to the base 1 of the clamping component A3 and clamping component B4. After the V-shaped pressure groove block 8 of the clamping and flattening mechanism 5 is fixed to the clamping component A3 with the flat pressure plate 9, the connecting block 6 with the flat connecting edge plate 14 is fixed to the clamping component B4. Then, a T-shaped glue spring post 11 is installed in the V-shaped groove 7 of the connecting block 6, and a raised glue plate 13 is installed in the V-shaped pressure groove of the V-shaped pressure groove block 8. Subsequently, the perforated blocks of clamping components A3 and B4 can extend into the base 1 and be installed with bolts and a gripper cylinder for easy counter-drive. When the dispensing valve needle descends between clamping components A3 and B4, the gripper cylinder can drive the clamping... When component A3 and clamping component B4 move closer together, the V-shaped pressure groove block 8 and the connecting block 6 clamp the wiping tape 2, causing the wiping tape 2 to contract towards the surface of the dispensing valve needle for wiping. At this time, the wiping tape 2 above the base 1 can be wound up, and the wiping tape 2 can wipe away the adhesive on the surface of the dispensing valve needle during the winding process. At the same time, the T-shaped adhesive spring column 11 can flexibly support the wiping tape 2 as it approaches the dispensing valve needle in conjunction with the convex strip adhesive plate 13, allowing the wiping tape 2 to have a large contact area with the dispensing valve needle for wiping. After the dispensing valve needle rises after wiping, clamping component A3 and clamping component B4 can move closer together, so that the flat pressure plate 9 at clamping component A3 and the flat connecting edge plate 14 at clamping component B4 clamp the wiping tape 2 after wiping, preventing wrinkles from appearing on the wiping tape 2 after wiping.
