[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] like Figure 1-7 As shown, this utility model provides an adhesive tape applicator, including a mounting base plate 1, a roll assembly 2 disposed on the mounting base plate 1, an adhesive tape pulling scissor assembly 3, and a pressing adhesive tape applicator 4 located above the adhesive tape pulling scissor assembly 3. The adhesive tape pulling scissor assembly 3 includes a film pulling mechanism 31 and a scissor mechanism 32. The film pulling mechanism 31 includes a first cylinder 311 and a pressure claw 312 connected to the first cylinder 311, a second cylinder 313 and a gripper 314 connected to the second cylinder 313. The material roll assembly 2 is used to convey and guide the adhesive tape, and the film pulling mechanism 31 is used to tighten the adhesive tape. In use, the platform for fixing the product (such as the back of a flat screen and the test cable that needs to be fixed) moves to the bottom of the adhesive tape scissor assembly 3 and stops at the position where the adhesive tape needs to be applied. The gripper 314 inserts between the pressure claw 312 to clamp the adhesive tape, and then the pressure claw 312 releases. The gripper 314 pulls the adhesive tape to the specified length, and then the pressure claw 312 presses down on the adhesive tape. The pressing adhesive application assembly 4 descends to the position of the adhesive tape and picks up the adhesive tape. The scissor mechanism 32 extends and cuts the adhesive tape. Then the gripper 314 releases, and the pressing adhesive application assembly 4 continues to press down to complete the adhesive tape application action. After that, the pressing adhesive application assembly 4 rises to complete the adhesive application process.

[0027] The overall structure is reasonably designed, which can fix the test cable on the back of the tablet screen and automatically apply adhesive tape, thereby improving testing efficiency.

[0028] The roll assembly 2 includes a roll 21 mounted on the mounting base plate 1, a damper 22 connected to the roll 21, and a guide wheel assembly 23 for guiding. The damper 22 and the clamping claw 312 or gripper 314 cooperate to straighten the adhesive tape.

[0029] The mounting base plate 1 is set on the mounting column 5 to achieve three-dimensional installation and also to reserve space for products that need to be glued.

[0030] The first cylinder 311 is mounted on the cylinder mounting plate 315. The second cylinder 313 is connected to the timing belt clamp 317 via the connecting plate 316. The timing belt clamp 317 clamps the timing belt 318, which is sleeved around the drive pulley 319 and the driven pulley 3110. The drive pulley 319 is connected to the stepper motor 3111. The stepper motor 3111 drives the rotation of the drive pulley 319, which in turn drives the timing belt 318, thereby causing the timing belt clamp 317, the connecting plate 316, the second cylinder 313, and the gripper 314 to move left and right.

[0031] A sensor 11 is installed on the mounting base plate 1, and a sensing sheet metal 3112 is installed on the connecting plate 316, which are used to control the tape to reach the specified length position.

[0032] The scissor mechanism 32 includes a pneumatic scissor 321, a dual-axis slide cylinder 322, and a slide cylinder mounting plate 323. The slide cylinder mounting plate 323 is mounted on the mounting base plate 1, and the dual-axis slide cylinder 322 is mounted on the slide cylinder mounting plate 323. The pneumatic scissor 321 is driven by the dual-axis slide cylinder 322. The dual-axis slide cylinder 322 can drive the movement of the pneumatic scissor 321 to realize the cutting operation of the adhesive tape.

[0033] The pressure-applying assembly 4 includes a servo motor 41, a linear module 42, a fixed base plate 43 driven by the linear module 42, a linear slide rail 44 mounted on the fixed base plate 43, a pressure fixing plate 45 connected to the linear slide rail 44, and an adhesive-applying suction plate 46 connected to the pressure fixing plate 45. The adhesive-applying suction plate 46 is connected to a vacuum generator 47 and has through holes. When the vacuum generator 47 performs a vacuuming action, the adhesive-applying suction plate 46 is in a vacuum state, which facilitates the suction of the adhesive tape, maintains the lateral flatness of the entire adhesive tape, and facilitates subsequent pressing and applying of the adhesive tape, preventing the problem of the adhesive tape falling off after cutting and causing uneven application.

[0034] When the adhesive-coating suction plate 46 is pressed down, it is located between the scissor mechanism 32 and the gripper 314, especially between the pneumatic scissors 321 and the gripper 314, which facilitates the suction and pressing of the adhesive tape, ensuring the flatness and aesthetics of the applied adhesive tape.

[0035] A pressure sensor 48 is provided on the pressure fixing plate 45, and a spring limit block 49 is provided on the linear slide rail 44. A spring 410 is provided between the pressure sensor 48 and the spring limit block 49 to control the pressure when applying the adhesive tape.

[0036] The working principle of this utility model is as follows: The material roll assembly guides the adhesive tape manually as shown in the figure, and places the end of the adhesive tape between the adhesive tape pulling scissor assembly 3. The left pressure claw 312 is pressed to tighten the adhesive tape, completing the adhesive tape feeding. The flat screen, carrying the test cable that needs to be fixed, moves to the platform with the back facing up, and moves to the position below the adhesive tape pulling scissor assembly 3, stopping at the position where the adhesive tape needs to be applied. The right gripper 314 of the adhesive tape pulling scissor assembly 3 inserts between the left pressure claw 312 and clamps the adhesive tape. Then the left pressure claw 312 releases, and the right gripper 314 pulls the adhesive tape to the specified length through step control. Under the action of the damper 22 of the material roll assembly 2, the adhesive tape can be straightened, and the left pressure claw 312 clamps the adhesive tape again. The pressing adhesive application assembly 4 opens the vacuum and descends to the position of the adhesive tape to pick it up. The scissor assembly 32 extends and cuts the adhesive tape, and then the right gripper 314 releases. The pressing adhesive application assembly 3 continues to press down to complete the adhesive tape application action, and at the same time breaks the vacuum and rises, completing the adhesive tape application process.

[0037] In summary, this invention can fix the test cable on the back of the tablet screen, automatically apply adhesive tape, and improve testing efficiency.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and structure of the present invention, the scope of which is defined by the appended claims and their equivalents.
