Description

Technical Field

[0001] The utility model relates to a zipper head assembly device, in particular to a zipper retaining frame pressing mechanism. Background Art

[0002] A zipper is a connector that connects or separates items by means of continuously arranged chain teeth. It is now widely used in clothing, bags, tents, etc. The zipper head 90, which is the main component of the zipper, consists of four parts, such as the attached Figure 7 As shown, the zipper head includes a slider 9001, a pull tab 9002, a spring and a holder 9003. The slider has two inlets and one meshing outlet, and is connected to the lower plate through a support core. The slider is a sheet structure, and the part in contact with the slider is wider than the user's handheld part. The slider and the slider are connected together through the spring. The holder is a "C"-shaped structure, which is formed by sheet stamping. The right side of the "C"-shaped structure has a cavity covering the top protrusion of the slider. The holder is mounted on the top protrusion of the slider and covers the outside of the spring, so that the slider can swing in the inner space of the "C"-shaped structure of the holder, which is convenient for use. Existing zipper head automatic assembly equipment can often quickly assemble the slider, the pull tab and the spring to form a zipper head, but when the customer needs a zipper head equipped with a holder, the holder can only be assembled manually. During manual assembly, the position of the slider needs to be adjusted to align with the anchor rod for compaction. Its production efficiency is low and it is difficult to meet actual requirements. In view of the above defects, it is necessary to design a zipper retainer clamping mechanism. Utility Model Content

[0011] Furthermore, the air distribution plate is also provided with air distribution holes, and the air distribution holes sequentially penetrate the air distribution plate and the rubber plate.

[0012] Compared with the prior art, the zipper holder clamping mechanism, when working, places the slider on the rubber plate in the positioning assembly, the positioning assembly clamps the slider, the clamping claw cylinder drives the two symmetrically arranged clamps to move relative to each other, and the limit assembly moves relative to the clamp.

DETAILED DESCRIPTION

[0021] like Figure 1 , Figure 2 As shown, a zipper holder clamping mechanism includes a base plate 1, a clamping cylinder 2, a chuck 3, a limiting assembly 4, an ejection assembly 5, an air inlet hole 6, a positioning assembly 7, and a first air inlet pipe 8. The clamping cylinder 2 is installed on the left side of the base plate 1. The number of the chucks 3 is 2, which are symmetrically arranged along the front and rear directions of the clamping cylinder 2. The chuck 3 is also provided with an anchor rod 301, and the anchor rod 301 is installed at the lower end of the chuck 3. The limiting assembly 4 is installed at the lower end of the chuck 3 and slides along the front and rear directions of the base plate 1. The ejection assembly 5 passes through the base plate 1, and the air inlet hole 6 passes through the base plate 1. The positioning assembly 7 is fixed to the left side of the base plate 1 and is penetrated by the ejection assembly 5. The positioning assembly 7 is opposite to the limiting assembly 4 and covers the air inlet hole 6. The first air inlet pipe 8 is installed on the right side of the base plate 1, and the first air inlet pipe 8 is communicated with the cavity of the air inlet hole 6.

[0022] like Figure 3As shown, the limit assembly 4 also includes a slider 401, a slide bar 402, a make-break hole 403, a first push head 404, a rubber block 405, and a first spring 406. The slider 401 is fixed to the lower end of the clamp 3 and slides along the bottom plate 1. The slide bar 402 is installed on the outside of the slider 401 and inserted into the bottom plate 1. When the limit assembly 4 is used in pairs, the slide bars 402 are respectively installed on the upper and lower sides of the slider 401 to prevent interference when installed on the same side. The make-break hole 403 runs through the main body of the slide bar 402, and the right side of the first push head 404 extends into the inner side of the slider 401. The first push head 404 slides along the slider 401, the rubber block 405 is located on the left side of the first push head 404, and the first spring 406 is located between the first push head 404 and the inner wall of the slider 401. When the jaw cylinder 2 closes its jaws, the two relatively arranged clamps 3 drive the limit assembly 4 to move relative to each other, so that the slider 401 and the slide rod 402 slide along the bottom plate 1. When the rubber block 405 fixedly connected to the first push head 404 contacts the pull head, as the jaw cylinder 2 continues to move, the first spring 406 compresses and reacts on the first push head, so that the two symmetrically arranged first push heads 404 drive the rubber block 405 to clamp the pull head in the left and right directions. In this process, the slide rod 402 blocks the air inlet 6. When the on-off hole 403 coincides with the air inlet 6, the first air inlet pipe 8 draws the air inlet 6 into a negative pressure, and then sucks the pull head tightly through the positioning assembly 7, thereby preventing the pull head from shaking when clamped. The shape of the on-off hole is elliptical. The elliptical on-off hole 403 helps to prolong the adsorption time of the pull head and improve the clamping yield.

[0023] like Figure 4 As shown, the ejection assembly 5 also includes a cylinder body 501, a piston 502, a second push head 503, a second spring 504, and a second air inlet pipe 505. The cylinder body 501 is located on the right side of the base plate 1, and the cylinder body 501 is connected to the base plate 1 by bolts. The piston 502 is located on the inner side of the cylinder body 501, and the piston 502 slides along the cylinder body 501. One end of the second push head 503 is connected to the piston 502, and the other end of the second push head 503 passes through the base plate 1 and the positioning assembly 7 respectively. The second spring 504 is located on the outer side of the second push head 503 and between the piston 502 and the inner side wall of the cylinder body 501. The second air inlet pipe is located on the outer side of the cylinder body 501 and communicates with the cavity of the cylinder body. Compressed air is pumped into the cylinder body 501 through the second air inlet pipe 505, and the piston 502 is pushed to drive the second push head 503 to move forward to pass through the positioning assembly 7 to eject the pull head. Subsequently, the second spring 504 is reset, and the piston 502 is pushed to drive the second push head 503 to reset.

[0024] like Figure 5As shown, the positioning assembly 7 also includes an air distribution plate 701, a rubber plate 702, and a positioning plate 703. The air distribution plate 701 is installed on the left side of the bottom plate 1. The air distribution plate 701 covers the air inlet hole 6 and is penetrated by the second push head 503. The rubber plate 702 is installed on the upper end of the air distribution plate 701. The number of the positioning plates 703 is 2, which are symmetrically arranged along the left and right directions of the air distribution plate 701. The positioning plate 703 is also provided with a limiting protrusion 704, and the material of the limiting protrusion 704 is nylon. The air distribution plate 701 is also provided with an air distribution hole 705. The air dividing holes 705 pass through the air dividing plate 701 and the rubber plate 702 in sequence. When the slider is placed on the rubber plate 702, the limiting protrusion 704 on the positioning plate 703 is deformed under pressure to clamp the slider. When the on-off hole 403 coincides with the air inlet hole 6, the air inlet hole 6 is evacuated into a negative pressure through the first air inlet pipe 8, thereby sucking the slider through the air dividing holes 705 on the air dividing plate 701. The rubber plate 702 is deformed, which is used to seal the contact surface between the slider and the air dividing hole 70 on the one hand, and on the other hand, works together with the limiting protrusion 704 to make the slider close to the rubber plate 702, thereby improving the adsorption and clamping effect.

[0025] like Figure 6 As shown, the slider is placed on the rubber plate 702 in the positioning assembly 7, the positioning assembly 7 clamps the slider, the clamping claw cylinder 2 drives the two symmetrically arranged clamps 3 to move relative to each other, and the limiting assembly 4 moves relative to the clamp 3. In this process, the first push head 404 in the limiting assembly 4 drives the rubber block 405 to clamp the slider in the left and right directions. At the same time, the air inlet 6 is pumped into a negative pressure through the first air inlet pipe 8. When the on-off hole 403 slides with the limiting assembly 4 and overlaps with the air inlet 6, the slider is tightly adsorbed on the rubber plate 702 of the positioning assembly 7. The anchor rod 301 on the clamp 3 presses the slider and the holder under the action of the clamping claw cylinder 2. Then, the clamping claw cylinder 2 returns, and the ejection assembly 5 ejects the slider. The device has a simple structure, and the positioning clamping of the slider and the rapid pressing of the holder can be achieved through the action of a single clamping claw cylinder, which greatly improves the work efficiency.

[0026] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
