Detailed Implementation

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1, please refer to Figures 1-6 An adhesive applicator includes a first support plate 1 and a first connecting shaft 103 mounted on the first support plate 1. A second support plate 101 is rotatably connected to the outer surface of the first connecting shaft 103. A first cylinder 102 is hinged between the second support plate 101 and the first support plate 1. An adhesive roll fixing structure 2 is provided on the first support plate 1. A connecting seat 3 is mounted on the second support plate 101. A heat-melting cutter 4 and a first connecting frame 301 are connected to the bottom end of the connecting seat 3. A first pressure roller 302 is rotatably connected to the inner side of the first connecting frame 301. A limit structure 5 is installed on one side of the connecting seat 3.

[0033] The heat-melting cutter 4 is an existing structure, and its specific structure and the method of heat-melting and cutting the tape are existing technologies, which will not be described in detail in this application.

[0034] The limiting structure 5 includes a second connecting frame 501 mounted on the limiting structure 5. A second cylinder 502 is mounted on the second connecting frame 501. The piston rod of the second cylinder 502 is connected to a third connecting frame 503. Two connecting rods 504 are interlaced on the third connecting frame 503. A fourth connecting frame 505 is connected between the bottom ends of the two connecting rods 504. A second pressure roller 506 is rotatably connected to the fourth connecting frame 505. In this application, by setting the first pressure roller 302 and the limiting structure 5, when applying tape, the second cylinder 502 drives the second pressure roller 506 to press the product, reducing the lifting of the product during the tape application process. The first pressure roller 302 rolls and presses the tape together, thereby improving the tape's bonding effect.

[0035] Furthermore, a first connecting plate 508 is connected between the top ends of the two connecting rods 504. The first connecting plate 508 is connected to the connecting rods 504 by bolts. The first connecting plate 508 and the third connecting frame 503 can limit the top end of the connecting rods 504, so that when the second cylinder 502 drives the third connecting frame 503 to rise, the third connecting frame 503 can drive the connecting rods 504, the fourth connecting frame 505 and the second pressure roller 506 to rise through the first connecting plate 508.

[0036] Furthermore, a spring 507 is sleeved on the outer surface of the connecting rod 504. The two ends of the spring 507 abut against the third connecting frame 503 and the fourth connecting frame 505 respectively. The force of the second pressure roller 506 can play a buffering role when the second pressure roller 506 contacts the product.

[0037] Furthermore, a pushing structure 8 is provided on the back of the second support plate 101. The pushing structure 8 includes a fourth cylinder 801 installed on the back of the second support plate 101. The piston rod of the fourth cylinder 801 is connected to a second connecting plate 802. The second connecting plate 802 is connected to a pneumatic slide rail 803. The pneumatic slide rail 803 is connected to a connecting arm 804. A push plate 805 is connected to the side of the connecting arm 804 near the bottom of the connecting seat 3. The pneumatic slide rail 803 can drive the connecting arm 804 and the push plate 805 to move closer to or further away from the connecting seat 3. The fourth cylinder 801 can push the connecting arm 804 to move along the length direction of the connecting seat 3 through the second connecting plate 802 and the pneumatic slide rail 803, thereby enabling the connecting arm 804 to push the tape to move. In use, the tape is conveyed forward so that the tape can reach the first pressure roller 302.

[0038] Furthermore, a U-shaped limit frame 806 is installed on the second connecting plate 802, and one end of the connecting arm 804 is located inside the U-shaped limit frame 806. The U-shaped limit frame 806 can limit the stroke of the connecting arm 804 driven by the pneumatic slide rail 803.

[0039] Furthermore, two guide rollers 6 are installed on the second support plate 101. A limit ring 601 is fixed to the outer surface of the guide roller 6 by bolts. The limit ring 601 can limit the tape passing through the guide roller 6. Since the limit ring 601 is fixed by bolts, the position of the limit ring 601 can be adjusted.

[0040] Furthermore, the film fixing structure 2 includes a second connecting shaft 201 mounted on the first support plate 1 via a bearing. The outer surface of the second connecting shaft 201 is fitted with a baffle 202, a baffle 203, and a fixing ring 204. The fixing ring 204 is provided with fixing bolts, and the ends of the bolts abut against the second connecting shaft 201, so that the tape roll can be fixed between the baffle 202 and the baffle 203.

[0041] Furthermore, a magnetic powder brake 207 is installed on the first support plate 1. The magnetic powder brake 207 and the second connecting shaft 201 are both connected to a synchronous belt 205. A synchronous pulley 206 is connected between the two synchronous belts 205. The magnetic powder brake 207, the synchronous pulley 206 and the synchronous belt 205 cooperate with each other to brake the second connecting shaft 201 to reduce the loosening of the belt. The magnetic powder brake 207 is an existing structure, and its structure and principle are existing technologies, which will not be described in detail in this application.

[0042] Example 2 further optimizes the adhesive application mechanism provided in Example 1, specifically, as follows: Figure 4 As shown, the top surface of the connector 3 is provided with a cutting structure 7, which is used to cut the tape. By cutting the tape with the cutting structure 7, this application can perform adhesive application on two products at the same time.

[0043] Furthermore, the slitting structure 7 includes a fifth connecting frame 701 mounted on the connecting seat 3. A third cylinder 702 is mounted on the fifth connecting frame 701. The third cylinder 702 is connected to a blade holder 703, and a slitting blade 704 is connected to the blade holder 703. The fifth connecting frame 701 can support the third cylinder 702, and the third cylinder 702 can drive the blade holder 703 and the slitting blade 704 to rise and fall. When the slitting blade 704 falls, it slits the tape; when the slitting blade 704 rises, it does not slit the tape, thus meeting different adhesive application conditions.

[0044] The adhesive applicator provided by this utility model is used as follows:

[0045] After loosening the bolts between the retaining ring 204 and the second connecting shaft 201, remove the baffle 203 and the retaining ring 204. Then, roll the tape around the outer surface of the second connecting shaft 201. Next, roll the baffle 203 and the retaining ring 204 around the outer surface of the second connecting shaft 201 in sequence. Then, fix the retaining ring 204 with bolts. Pass the tape between the two guide rollers 6, then between the push plate 805 and the connecting seat 3, and then through the first pressure roller 302.

[0046] The first support plate 1 is connected to the existing robot arm, so that the robot arm can drive the application to move. When applying the adhesive, the first pressure roller 302 presses the tape onto the product, while the second cylinder 502 drives the second pressure roller 506 to descend to press the product. When the tape is applied to the required length, the pneumatic slide rail 803 drives the connecting arm 804 and the push plate 805 to move towards the connecting seat 3. The push plate 805 drives the tape to move towards the hot melt cutter 4 so that the tape contacts the hot melt cutter 4. The hot melt cutter 4 heats the tape to cut it. After cutting, the hot melt cutter 4 stops heating.

[0047] When continuing to apply adhesive, the fourth cylinder 801 pushes the second connecting plate 802 toward the first pressure roller 302, which in turn causes the pneumatic slide rail 803, connecting arm 804 and push plate 805 to move toward the first pressure roller 302. The push plate 805 pushes the tape toward the first pressure roller 302, so that the first pressure roller 302 can press the tape onto the product for adhesive application. After the first pressure roller 302 presses the tape onto the product, the push plate 805 resets and moves away from the connecting seat 3.
