[0002] In the production process of electronic or mechanical equipment, it is necessary to attach one side of double-sided tape to one side of the product and then peel off the release paper. The current method uses a box-type tape machine to cut the double-sided tape and release paper to the required length, and then the double-sided tape is manually applied to the product surface and the release paper is peeled off. This method is labor-intensive and very inefficient. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the aforementioned background technology and provide a double-sided adhesive application mechanism that automatically unwinds the adhesive tape, automatically applies the adhesive, automatically peels off the release liner, automatically rewinds the release liner, replaces manual operation, and improves the efficiency of double-sided adhesive application.

[0004] To achieve this objective, the double-sided tape application mechanism designed in this invention includes a support frame. The support frame is equipped with an adhesive unwinding mechanism for mounting the double-sided tape and a release paper winding mechanism for winding up the release paper. Between the adhesive unwinding mechanism and the release paper winding mechanism are a tape cutting mechanism for cutting the adhesive tape without cutting the release paper, and an adhesive application mechanism for attaching the double-sided tape to the product surface. The double-sided tape is mounted on the adhesive unwinding mechanism, and one end of the double-sided tape passes sequentially around the tape cutting mechanism and the adhesive application mechanism before being fixed to the release paper winding mechanism.

[0005] Furthermore, the mechanism support is also provided with a tape length measuring mechanism located between the tape cutting mechanism and the tape applying mechanism, which is used to calculate the length of the double-sided tape pulled out. One end of the double-sided tape passes through the tape cutting mechanism, the tape length measuring mechanism and the tape applying mechanism in sequence and is fixed to the release paper winding mechanism.

[0006] Furthermore, a product pushing mechanism for pushing the product to the adhesive application position is also provided below the adhesive application mechanism.

[0007] Furthermore, the cutting mechanism includes a pad mechanism and a cutting mechanism arranged vertically; the pad mechanism includes a pad bracket fixed to the mechanism support and a cutting pad located below the pad bracket, and a pad adjustment mechanism for adjusting the vertical position of the cutting pad is connected between the pad bracket and the cutting pad; the cutting mechanism includes a cutting blade and a cutting blade drive mechanism for driving the cutting blade to move vertically.

[0008] Furthermore, the pad adjustment mechanism includes a guide hole opened at the bottom of the pad bracket, a guide post fixed at the top of the cutter pad that mates with the guide hole, and a connecting spring coaxially arranged with the guide post fixed between the pad bracket and the guide post; the pad bracket is internally threaded with an adjusting bolt for pushing the cutter pad and adjusting the distance between it and the pad bracket, the bottom of the adjusting bolt is in close contact with the top of the cutter pad, and the middle part of the adjusting bolt is threaded into the pad bracket.

[0009] Furthermore, the cutter driving mechanism includes a cutter driving cylinder fixed on the mechanism bracket, and the cutter is fixed on the piston rod of the cutter driving cylinder.

[0010] Furthermore, the adhesive applicator includes a slide rail fixed to the mechanism bracket along the bonding direction of the double-sided adhesive on the product, an adhesive applicator bracket slidably disposed on the slide rail, and an adhesive applicator cylinder for driving the adhesive applicator bracket to reciprocate along the slide rail; the adhesive applicator bracket is rotatably connected with peeling rollers and pressing rollers arranged vertically, and the double-sided adhesive is fixed to the release paper winding mechanism by passing around the pressing rollers and the peeling rollers in sequence.

[0011] Furthermore, the tape length measuring mechanism includes a bearing seat fixed to the front of the mechanism support and an encoder fixed to the back of the mechanism support. A bearing is provided in the bearing seat, and a roller is connected to the bearing. One end of the roller passes through the bearing and the mechanism support and connects to the encoder. A roller is fixed on the roller, and the double-sided tape passes around the roller.

[0012] Furthermore, the product pushing mechanism includes a pushing bracket and a pushing cylinder fixed on the pushing bracket, and a product mounting seat for placing the product is fixed to the top of the piston rod of the pushing cylinder.

[0013] Furthermore, the mechanism support is provided with a limiting structure that cooperates with the product, restricts the product's pushing position, and positions the product in the adhesive application position.

[0014] The beneficial effects of this invention are: This invention cuts the adhesive tape using a cutting mechanism while maintaining an uninterrupted release liner; the release liner is directly wound up by a rewinding mechanism; and simultaneously, the adhesive tape is applied to the product surface by an applicating mechanism.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1The double-sided adhesive applicator shown in Figure 2 includes a support frame 1. The support frame 1 is equipped with an adhesive unwinding mechanism 2 for mounting the double-sided adhesive and a release paper winding mechanism 9 for winding the release paper 10. Between the adhesive unwinding mechanism 1 and the release paper winding mechanism 9 are a cutting mechanism 3 for cutting the adhesive without cutting the release paper 10, an adhesive length measuring mechanism 4 for calculating the pulled-out length of the double-sided adhesive 11, an applicating mechanism 5 for attaching the double-sided adhesive 11 to the surface of the product 12, and a transition wheel 6. The adhesive unwinding mechanism 2 includes an adhesive mounting plate 2.1 on which the double-sided adhesive 11 is mounted. The release paper winding mechanism 9 includes a release paper winding reel 9.2 and a winding motor 9.1. One end of the double-sided adhesive 11 passes sequentially around the cutting mechanism 3, the adhesive length measuring mechanism 4, the applicating mechanism 5, and the transition wheel 6 and is fixed to the release paper winding reel 9.2. The winding motor 9.1 drives the release paper winding reel 9.1 to rotate and wind the release paper 10. Below the adhesive applicator 5, there is a product pushing mechanism 8 for pushing the product 12 to the adhesive applicator position. The product pushing mechanism 8 includes a pushing bracket 8.1 and a pushing cylinder 8.2 fixed to the pushing bracket 8.1. A product mounting seat 8.3 for placing the product 12 is fixed to the top of the piston rod of the pushing cylinder 8.2. The mechanism bracket 1 is provided with a limiting block 13 and a limiting rod 7 that cooperate with the product 12, limit the pushing position of the product 12, and position the product 12 in the adhesive applicator position. The limiting block 13 and the limiting rod 7 hold the two ends of the product 12 against each other, positioning the product 12 in the adhesive applicator position. The inner side of the limiting block 13 has a cut edge to facilitate the peeling of the release paper 10.

[0024] like Figure 3 As shown, the cutting mechanism 3 includes a pad mechanism and a cutting mechanism arranged vertically. The pad mechanism includes a pad bracket 3.1 fixed on the mechanism support 1 and a cutting pad 3.2 located below the pad bracket 3.1. A pad adjustment mechanism for adjusting the vertical position of the cutting pad 3.2 is connected between the pad bracket 3.1 and the cutting pad 3.2. The pad adjustment mechanism includes a guide hole opened at the bottom of the pad bracket 3.1. A guide post 3.4 that mates with the guide hole is fixed at the top of the cutting pad 3.2. A connecting spring 3.5 coaxially arranged with the guide post 3.4 is fixed between the pad bracket 3.1 and the guide post 3.4. An adjusting bolt 3.6 for pushing the cutting pad 3.2 and adjusting the distance between it and the pad bracket 3.1 is internally threaded onto the pad bracket 3.1. The bottom of the adjusting bolt 3.6 is in close contact with the top of the cutting pad 3.2, and the middle part of the adjusting bolt 3.6 is threaded into the pad bracket 3.1. The cutting mechanism includes a cutter 3.3 and a cutter drive cylinder 3.7 for driving the cutter 3.3 to move up and down. The cutter 3.3 is fixed on the piston rod of the cutter drive cylinder 3.7.

[0025] like Figure 4As shown in Figure 5, the tape length measuring mechanism 4 includes a bearing seat 4.1 fixed to the front of the mechanism support 1 and an encoder 4.2 fixed to the back of the mechanism support 1. A bearing 4.3 is provided inside the bearing seat 4.1. A roller 4.4 is connected to the bearing 4.3. One end of the roller 4.4 passes through the bearing 4.3 and the mechanism support 1 to connect to the encoder 4.2. A roller 4.5 is fixed on the roller 4.4. Double-sided tape 11 passes around the roller 4.5.

[0026] like Figure 1 —2 and Figure 6 The adhesive applicator 5 includes a slide rail 5.1 fixed on the mechanism bracket 1 along the pasting direction of the double-sided adhesive 11 on the product 12, an adhesive applicator bracket 5.2 slidably disposed on the slide rail 5.1, and an adhesive applicator cylinder 5.3 for driving the adhesive applicator bracket 5.2 to reciprocate along the slide rail 5.1; the adhesive applicator bracket 5.2 is rotatably connected with peeling rollers 5.4 and pressing rollers 5.5 arranged vertically, and the double-sided adhesive 11 passes through the pressing roller 5.5, peeling roller 5.4 and transition roller 6 in sequence and is fixed on the release paper take-up reel 9.2. The adhesive-applying cylinder 5.3 drives the adhesive-applying bracket 5.2 to reciprocate along the slide rail 5.1. The left limit position of the adhesive-applying bracket 5.2 is limited by the cooperation of the limiting plate 5.6 and the transition wheel 6. The right limit position of the adhesive-applying bracket 5.2 is limited by the cooperation of the limiting plate 5.6 and the limiting rod 7. The pressure roller 5.5 presses the release paper 10 through the pressure spring 5.7. The pressure roller 5.5 moves from left to right to stick and fix the double-sided adhesive 11 to the top surface of the product 12.

[0027] The adhesive application process of the double-sided tape application mechanism designed in this invention is as follows: the double-sided tape 11 is installed on the tape mounting plate 2.1, the double-sided tape 11 passes through the tape cutting mechanism 3, the tape length measuring mechanism 4, the limiting rod 7, the tape pressing wheel 5.5, the tape peeling wheel 5.4 and the transition wheel 6 in sequence, and finally the head of the release paper 10 is fixed on the release paper winding plate 9.2. The winding motor 9.1 rotates, pulling the double-sided adhesive 11 unwind. The encoder 4.2 calculates the length of the adhesive paper pulled out. After the adhesive paper is pulled out to the specified length, the cutter 3.3 of the adhesive cutting mechanism 3 moves upward and cooperates with the cutter pad 3.2 to cut the double-sided adhesive 11 located between the cutter pad 3.2 and the cutter 3.3, but does not cut the release paper 10. The winding motor 9.1 continues to pull the release paper 10 so that the specified length of double-sided adhesive 11 reaches the adhesive application position. The cut of the double-sided adhesive 11 is at the cutting point of the limit block 13, which facilitates subsequent peeling. The push cylinder 8.2 drives the product 12 to move upward, so that the product 12 is bonded to the double-sided adhesive 11. The adhesive application cylinder 5.3 pushes the peeling wheel 5.4 and the pressing wheel 5.5 in the direction of unwinding the adhesive paper. Figure 1 Rolling from left to right makes the double-sided adhesive 11 adhere more tightly to the product 12 while peeling off the release paper 10. After the adhesive is applied, the product 12 descends, the adhesive cylinder 5.3 drives the adhesive bracket 5.2 to retract, and the winding motor 9.1 continues to pull the release paper 10 to prepare for the next adhesive application. This process is repeated.

[0028] In summary, this invention achieves automatic application of double-sided tape 11 and automatic removal and rewinding of the release paper 10 by the tape cutting mechanism 3, while the release paper winding mechanism 9 directly winds up the release paper 10. Simultaneously, the tape is adhered to the surface of the product 12 by the tape application mechanism 5. This realizes the functions of automatic tape application and automatic removal and rewinding of the release paper 10, replacing manual tape application, greatly improving tape application efficiency, and saving tape application costs.

[0029] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the structure of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
