Description

Technical Field

[0001] This utility model relates to the field of adhesive application mechanism technology, and in particular to a bottom adhesive application device that prevents adhesive tape from being exposed and overlapping. Background Technology

[0002] Bottom tape applicator is a device used to automatically apply tape to the bottom of products, especially in the fields of cardboard packaging and lithium battery manufacturing. It aims to achieve efficient and accurate tape application and avoid problems such as tape skewing, overlapping, or bubbling.

[0003] According to Chinese Announcement No. CN217591237U, an adhesive backing device includes: a conveyor belt, a mounting frame, adhesive tape, and a clamping ring. The mounting frame is fixedly mounted on the conveyor belt, and the clamping ring is arranged below the mounting frame via a telescopic mechanism. The adhesive tape is movably mounted on the clamping ring. The device also includes: an adjustment mechanism, movably mounted on the mounting frame, used to adjust the pressing height of the adhesive tape. The adjustment mechanism includes: a motor, a pressure plate, two sets of movable grooves, a threaded rod, and a fixed rod. This invention uses the motor to rotate the threaded rod, thereby causing the threaded pressure plate to rise and fall to adhere to the PCB board, allowing the adhesive tape to adhere to the PCB board. This achieves the effect of adjusting the pressure plate to facilitate adhesive tape adhesion to the PCB board. A tape contact sensor causes the blade to rotate into the cutting groove, thereby achieving the effect of automatically cutting the adhesive tape.

[0004] Plastic tape reels may deform slightly after prolonged use. This deformation can cause the unwinding path to deviate, resulting in one end of the tape being exposed. Utility Model Content

[0007] Preferably, a horizontal moving component is provided on one side of the upper part of the workbench, and a fixed block is provided on the horizontal moving component. The horizontal moving component is driven by a motor to rotate the lead screw, which causes the fixed block to move on the track.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Example 1: Reference Figure 1-3 A bottom adhesive applicator that prevents tape from being exposed and overlapping includes: an adhesive applicator body, an object-assisted pushing structure 6, and an auxiliary flattening structure 7. The main body of the adhesive applicator includes: a worktable 1, a horizontal moving component 2, a fixed block 3, a tape placement roller 4, a rotary tape traction component 5, and a cutter 8. The horizontal moving component 2 is located on one side above the worktable 1, and the fixed block 3 is located on the horizontal moving component 2. The horizontal moving component 2 is driven by a motor to rotate the lead screw, which causes the fixed block 3 to move on the track. The tape placement roller 4 is located on the outer wall of the other side of the fixed block 3. The rotary tape traction component 5 is located in the middle of the outer wall of the fixed block 3. The cutter 8 is located on the outer wall of the fixed block 3 and is located next to the rotary tape traction component 5. The object auxiliary pushing structure 6 is located inside the worktable 1, and the auxiliary leveling structure 7 is located on one side of the outer wall of the fixed block 3.

[0019] The workpiece is placed on the workbench 1 and moved to the designated tape adhesion position. At this time, the rotary tape traction component 5 is activated and the angle is adjusted so that one end of the tape on the tape placement roller 4 can adhere to the surface of the workpiece. The horizontal moving component 2 drives the fixed block 3 to move. At this time, the fixed block 3 simultaneously drives the rotary tape traction component 5 and one end of the tape to adhere to the surface of the workpiece. The angle change of the rotary tape traction component 5 drives the tape to move upward and contact the cutting blade 8, thereby breaking the tape. During the movement of the fixed block 3, the tape on the workpiece can be tightly adhered and smoothed by the auxiliary pushing structure 7. The object-assisted pushing structure 6 can quickly move the workpiece after the work is completed, avoiding the phenomenon of workpiece accumulation.

[0020] Example 2: Reference Figure 1-3 A bottom adhesive applicator that prevents tape from being exposed and overlapping includes: an object-assisted pushing structure 6; The object-assisted pushing structure 6 includes: an L-shaped sliding hole 601 opened at one end of the top outer wall of the worktable 1; sliding grooves 602 opened on both sides of the inner wall of the L-shaped sliding hole 601; a pushing slider 603 horizontally slidably disposed inside the L-shaped sliding hole 601; positioning sliders 604 welded to both sides of the inner wall of the pushing slider 603; positioning sliders 604 horizontally slidably disposed inside the sliding grooves 602; a servo motor 605 disposed on the bottom outer wall of the worktable 1; a toggle rod 606 connected to the output end of the servo motor 605 via a shaft; a rectangular strip hole opened on the toggle rod 606; and a positioning post 607 welded to the bottom outer wall of the pushing slider 603; the positioning post 607 being disposed inside the rectangular strip hole of the toggle rod 606.

[0021] The servo motor 605 is started, which drives the actuating rod 606 connected to the output shaft to change its angle. Because the positioning post 607 at the bottom of the push slider 603 is located in the rectangular slot of the actuating rod 606, when the angle of the actuating rod 606 changes, it will cause the positioning post 607 and the push slider 603 to move. At this time, the push slider 603 can move inside the slide groove 602 through the positioning sliders 604 at both ends, so that the push slider 603 can move stably inside the L-shaped slide hole 601. By moving the push slider 603, the workpiece is moved to a different position, which can provide the workpiece to move quickly after completing the work and avoid the phenomenon of workpiece accumulation in the working area where the tape is stuck.

[0022] Example 3 Reference Figure 1-3 A bottom adhesive applicator that prevents tape from being exposed and overlapping includes: an auxiliary flattening structure 7; The auxiliary leveling structure 7 includes: a fixed plate 701 welded to one side of the outer wall of the fixed block 3; two sets of circular holes on the fixed plate 701; a guide rod 702 vertically slidably disposed in the two sets of circular holes of the fixed plate 701; a leveling roller 703 rotatably disposed at the bottom end of the guide rod 702; a compression spring 704 sleeved on the outside of the guide rod 702; the two ends of the compression spring 704 respectively attached to the outer wall of the leveling roller 703 and the fixed plate 701; and an arc plate 705 welded to the outer wall of the frame of the leveling roller 703, which is disposed beside the leveling roller 703.

[0023] When the fixed block 3 moves, the arc plate 705 on the outer wall of the flattening roller 703 will first contact the workpiece. Through the arc surface of the arc plate 705, the flattening roller 703 can move smoothly above the workpiece. At this time, the flattening roller 703 can achieve stable vertical movement through the guide rod 702 in the round hole of the fixed plate 701. Through the compression spring 704, the flattening roller 703 can be stably attached to the surface of the workpiece. At the same time as the fixed block 3, it can be attached to the surface of the workpiece and move together, which can smooth the tape on the workpiece and avoid the phenomenon of one end of the tape sticking up and being exposed.

[0024] 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 spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
