Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, in particular to a double-belt torsion counter-clamping glue wiping device. BACKGROUND

[0002] With the gradual miniaturization and lightness of intelligent electronic products, more and more intelligent wearable products begin to replace some functions of smart phones and become the favorites of young consumers. In order to integrate more electronic components into intelligent wearable products, the assembly of various parts cannot use screws and other connecting parts any more, but high-adhesion glue is used instead. Therefore, the glue dispenser becomes an essential automatic production tool for more intelligent wearable electronic products.

[0003] However, the glue discharged by the glue dispenser needs to be cured within a certain time, either quickly or slowly. For the discharged glue, it does not affect the glue dispensing needle of the glue dispenser, but the glue that has not been discharged and remains in or on the surface of the glue dispensing needle will cause the glue dispensing needle to be blocked by the cured glue within the specified time. Similarly, the glue on the surface of the glue dispensing needle that is not wiped clean will also be cured on the surface of the glue dispensing needle, affecting the subsequent glue dispensing action. Therefore, the wiping process and wiping device for the glue dispensing needle must be provided.

[0004] Most of the existing glue wiping devices are to tension the non-woven fabric belt for wiping into a V shape through a guide wheel, and to clamp the glue dispensing needle in the middle by the clamping jaws on both sides of the V-shaped non-woven fabric, so as to press the glue dispensing needle tightly against the surface of the non-woven fabric, and then to pull out the glue dispensing needle to complete the glue wiping. However, the V-shaped non-woven fabric needs to be provided with at least one guide wheel below the V shape and on the glue wiping surface of the non-woven fabric, which causes the front non-woven fabric to be contaminated with glue when it passes the guide wheel after wiping. Even when the glue dispensing needle is positioned for glue wiping, a drop of glue may also fall on the guide wheel. The non-woven fabric is contaminated by the guide wheel every time it releases new material, which causes the front half of the non-woven fabric to be clean and the back half of the non-woven fabric to be contaminated when the glue dispensing needle is wiped the next time. Therefore, theoretically, the glue dispensing needle cannot be completely wiped. This is a technical defect of the non-woven fabric belt glue wiping device. The effective use of the non-woven fabric belt is greatly reduced because more non-woven fabric belts are provided to wipe off the contaminated glue on the guide wheel.

[0005] The current solution to the above-mentioned glue wiping process "side effects" is to place the glue dispensing needle to be wiped in the middle of the non-woven fabric belt tensioned by two sets of non-woven fabric belts arranged side by side, and then to clamp and wipe the glue by the clamping assembly. However, the space occupied by the two sets of non-woven fabric belts on the market is extremely large, which increases the equipment cost by one time, occupies the use space of the automatic glue dispensing workbench, and cannot perfectly solve the glue wiping problem.

[0056] In order to reduce the occupied space of the glue wiping equipment, let the double feeding disc 2 and the double receiving disc 3 close to each other, reduce the occupation, at the same time, reduce the total length of the non-woven fabric 10 wound by the guide wheel 9, but in order to facilitate the clamping of the two vertical and side-by-side non-woven fabrics 10, avoid the position of the double feeding disc 2 and the double receiving disc 3, refer to Figure 2The borrowing position clamping assembly 7 needs to borrow the space on the other side of the rack 1.

[0057] As a further description of the technical solutions of the present embodiment, refer to Figure 7 The borrowing position clamping assembly 7 includes a support seat 701, an outer clamping block 703, an inner clamping block 702, a rotary cylinder 13, a sliding block sliding rail assembly 708, and an outer dial 704 and an inner dial 707 for driving the two clamping blocks to clamp or separate.

[0058] Further technical solutions are, refer to Figure 6 and Figure 7 The support seat 701 is connected with the rack 1, and the outer clamping block 703 is connected with the support seat 701 through the sliding block sliding rail assembly 708, so that the clamping movement direction of the outer clamping block 703 is always perpendicular to the surface of the non-woven fabric 10 twisted to a vertical posture.

[0059] Among them:

[0060] Refer to Figure 5 and Figure 7 The outer clamping block 703 is provided with a horizontally arranged inner concave sliding table and a vertically arranged outer clamping plate 7031, the inner concave sliding table is matched with the inner clamping block 702 through the inner concave sliding groove 7034, and is used to limit the sliding movement of the inner clamping block 702 and the outer clamping block 703 always parallel to each other, and the outer clamping plate 7031 is arranged outside the two non-woven fabric 10 material belts.

[0061] Refer to Figure 5 and Figure 7 The inner clamping block 702 is provided with a horizontally arranged outer convex sliding table and a vertically arranged inner clamping plate 7021, the outer convex sliding table is matched with the inner concave sliding table sliding groove provided on the outer clamping block 703, and the inner clamping plate 7021 is arranged inside the two non-woven fabric 10 material belts.

[0062] Obviously, through the synchronous, same speed and same force sliding clamping of the outer clamping plate 7031 and the inner clamping plate 7021 relative to or away from each other, the clamping speed, clamping force and clamping position of the two non-woven fabric belts can be accurately controlled, and the stability of the sliding movement of the equipment can be improved.

[0063] Further embodiments are, refer to Figure 7 The inner concave sliding table and the outer convex sliding table are both provided with a waist-shaped hole avoiding the rotation shaft 131 of the rotary cylinder 13, the length of the waist-shaped hole is greater than the displacement amount of the horizontal sliding, so that the outer clamping block 703 and the inner clamping block 702 can be driven to fully complete the relative clamping displacement amount within the rotation stroke, and the needle head to be wiped in the clamped non-woven fabric 10 is guaranteed.

[0064] As an important necessary technical feature of the embodiment, the waist-shaped hole 7032 of the inner sliding table is provided with an outer push sliding groove 7033 on one side, and the waist-shaped hole 7022 of the outer sliding table is provided with an inner push sliding groove 7023 on one side. The outer push sliding groove 7033 and the inner push sliding groove 7023 are arranged on both sides of the waist-shaped hole.

The outer dial pin 7041 is matched with the outer push sliding groove 7033 for sliding, and the inner dial pin 7071 is matched with the inner push sliding groove 7023 for sliding. With the one-way rotation of the rotating shaft 131, the outer dial pin 7041 and the inner dial pin 7071 distributed on both sides of the rotating shaft 131 rotate in opposite directions. This ensures that the outer push sliding groove 7033 and the inner push sliding groove 7023 can be pushed away in opposite directions under the driving of the rotating shaft 131 of the single rotating cylinder 13, so as to ensure that the outer clamping plate 7031 and the inner clamping plate 7021 can slide, clamp or release the two non-woven fabrics 10 in a synchronous, same-speed and same-force manner.

[0066] Further, in order to protect the precise part glue gun needle, hard contact or collision during glue wiping will not cause damage, referring to Figure 5 , Figure 6 and Figure 8 , the outer clamping plate 7031 and the inner clamping plate 7021 are both provided with soft clamping pieces 705, such as sponges, on the side facing the non-woven fabric 10.

The torsion rollers and the non-woven fabric 10 are matched in a rolling friction or sliding friction manner to adjust the posture of the non-woven fabric 10.

[0068] As an extension of the technical solution of the present embodiment, in order to ensure that the non-woven fabric 10 can be smoothly twisted by 90 degrees, and the release position after twisting has high accuracy, it is necessary to adjust the transition of the non-woven fabric 10 from horizontal to vertical posture. A pair of front and rear twisting rollers can be additionally provided between the guide wheel 9 arranged horizontally and the front twisting assembly 6, and arranged at 45 degrees in the center of the release path of the non-woven fabric 10. The upper and lower shaft heads are matched with the upper and lower twisting seats 602 and 601 respectively.
