Glue laminating station

Abstract

The present invention discloses a glue laminating station mechanism comprising a first workbench and a second workbench. The first workbench comprises a conveyor belt that conveys a steel sheet material strip toward a longitudinal front end. The steel sheet material strip comprises a base film, a backing adhesive and a steel sheet located on the base film. The second workbench comprises a fixed carrier, a positioning seat that moves longitudinally relative to the fixed carrier, and a positioning mechanism located at a longitudinal rear end. The positioning mechanism comprises a baffle that moves vertically. When the steel sheet moves to the longitudinal front end face of the conveyor belt, the positioning seat moves longitudinally to the longitudinal front end face of the conveyor belt. At this time, the backing adhesive drives the steel sheet to separate from the base film and move onto the positioning seat. The positioning seat then returns to its initial position. When the positioning seat returns to its initial position, the baffle moves upward to between the conveyor belt and the positioning seat. The positioning seat moves backward until it abuts against the front end face of the baffle. At this time, the backing adhesive and the steel sheet abut against the front end face of the baffle to form a coplanar steel sheet module. The steel sheet module has high positioning accuracy and a high yield rate.

Description

Technical Field

[0001] The present invention relates to a glue sticking station mechanism, in particular to a glue sticking station mechanism with high positioning accuracy. Background Art

[0002] The existing steel sheet positioning mechanism is used to attach adhesive backing to the bottom surface of the steel sheet to form a steel sheet module. This type of steel sheet positioning mechanism has the following positioning actions: first, the semi-finished steel sheet (the steel sheet is attached to the bottom film with adhesive backing) is limited in the flow channel by the guide plate in a belt-like manner; secondly, when the steel sheet reaches the edge of the flow channel, the positioning seat is pushed forward by the cylinder to 0.1mm away from the edge of the flow channel, and the bottom film is pulled downward by the motor, so that the steel sheet enters the positioning seat. Finally, the cylinder drives the positioning seat back to the starting point to form the above-mentioned steel sheet module. However, the positioning accuracy of this type of steel sheet positioning mechanism is poor: the steel sheet will be offset when it is peeled off from the bottom film and enters the positioning seat; because there is adhesive backing on the bottom of the steel sheet, and the adhesive backing will penetrate into the knife die stamping during die cutting, thereby generating adhesion; thus, the production yield of the steel sheet module is poor and the efficiency is low.

[0003] Therefore, it is hoped that a new glue sticking station mechanism is proposed to overcome the above-mentioned defects. Summary of the Invention

[0020] See Figures 1 to 4 As shown, a preferred embodiment of the present invention discloses a glue-applying station mechanism for applying adhesive backing to the bottom surface of a steel sheet to form a steel sheet module with high positioning accuracy. The glue-applying station mechanism includes a first workbench 100 and a second workbench 200 located at the longitudinal front end of the first workbench 100, that is, the first workbench 100 and the second workbench 200 are arranged side by side and facing each other in the longitudinal direction. The first workbench 100 is used to convey a steel sheet strip 300 toward the second workbench 200. The steel sheet strip 300 includes a longitudinal bottom film 301, adhesive backing located on the upper surface of the bottom film 301, and a steel sheet covered on top of the adhesive backing. The steel sheet and the adhesive backing together form a steel sheet module 302.

[0021] See also Figures 1 to 3As shown, the first workbench 100 includes a material belt conveying mechanism 10 located at the top. The material belt conveying mechanism 10 includes a conveyor belt 11 for conveying the steel sheet material belt 300 toward the longitudinal front end, a material guide plate 12 fixedly connected to the conveyor belt 11, and a fourth cylinder 13 connected to the conveyor belt 11. The conveyor belt 11 includes a flow channel 111 for carrying the steel sheet material belt 300 and guide rails 112 located on both sides of the flow channel 111. In this embodiment, the base film 301 is placed on the flow channel 111 of the conveyor belt 111. The flow channel 111 is used to convey the base film 301 toward the longitudinal front end, and the guide rails 112 are used to limit the movement direction of the base film 301 within the flow channel 111.

[0022] The guide plate 12 is fixedly connected to the guide rail 112 and extends at least partially horizontally above the flow channel 111. That is, the guide plate 12 is vertically positioned above the base film 301. This limits the vertical movement of the base film 301 and further guides the movement direction of the base film 301. The fourth cylinder 13 is connected to the conveyor belt 11, thereby driving the flow channel 111 of the conveyor belt 11 to move forward in the longitudinal direction, thereby conveying the steel sheet strip 300 toward the longitudinal front end.

[0023] The second workbench 200 includes a fixed carrier 20 fixed to the top and a positioning mechanism 60 located at the longitudinal rear end. The positioning mechanism 60 is located longitudinally between the first workbench 100 and the second workbench. The fixed carrier 20 includes a movable carrier 30 located above the fixed carrier 20 and a first cylinder 21 connected to the movable carrier 30. The first cylinder 21 drives the movable carrier 30 to move longitudinally relative to the fixed carrier 20. The movable carrier 30 includes a positioning carrier 40 located on the movable carrier 30 and a second cylinder 31 connected to the positioning carrier 40. The positioning carrier 40 includes a positioning seat 50 located at the longitudinal rear end. The second cylinder 31 drives the positioning carrier 40 to cause the positioning seat 50 to move longitudinally relative to the movable carrier 30.

[0024] In the present invention, the fourth cylinder 13 drives the flow channel 111 of the conveyor belt 11 to move forward in the longitudinal direction to drive the steel sheet material belt 300 to be transported toward the longitudinal front end; when the steel sheet on the base film 301 moves to the longitudinal front end surface of the conveyor belt 11, the first cylinder 21 drives the movable carrier 30 to drive the positioning carrier 40 to move backward in the longitudinal direction until the positioning seat 50 of the positioning carrier 40 moves to the longitudinal front end surface of the conveyor belt 11. At this time, the adhesive backing drives the steel sheet to separate from the base film 30 and move onto the positioning seat 50. Then, the first cylinder 21 drives the movable carrier 30 to drive the positioning seat 50 carrying the adhesive backing and the steel sheet to move forward in the longitudinal direction to return to its initial position.

[0025] The positioning mechanism 60 includes a baffle 61 located below and a third cylinder 62 connected to the baffle 61. The third cylinder 62 drives the baffle 61 to move vertically. When the positioning seat 50 carrying the adhesive and steel sheet returns to its initial position, the third cylinder 62 drives the baffle 61 to move vertically upward to between the conveyor belt 11 and the positioning seat 50. At this time, the second cylinder 31 drives the positioning carrier 40 to drive the positioning seat 50 to move backward in the longitudinal direction until the positioning seat 50 abuts the front end surface of the baffle 61. As a result, the adhesive and steel sheet abut against the front end surface of the baffle 61, allowing the steel sheet to fully enter the positioning seat 50. That is, the adhesive and steel sheet form a coplanar steel sheet module 302, thereby ensuring that the final formed steel sheet module 302 has high positioning accuracy, high yield rate, and high production efficiency.

[0026] In this embodiment, the fixed carrier 20 further includes a first stopper 22 located laterally. The first stopper 22 comprises a main body 221 fixed to the fixed carrier 20 and two protrusions 222 extending upward from the longitudinal ends of the main body 221. The movable carrier 30 includes a first stopper 32 extending downwardly from the lateral side, longitudinally located between the two protrusions 222. This limits the longitudinal range of motion of the movable carrier 30, preventing excessive movement of the movable carrier 30 by the first cylinder 21. Furthermore, the movable carrier 30 includes a second stopper 33 located laterally, at the longitudinal rear end of the movable carrier 30. The positioning carrier 40 includes a second stopper 41 protruding laterally outward. The second stopper 41 supports the positioning seat 50 and is located at the longitudinal rear end of the second stopper 33. This limits the longitudinal range of motion of the positioning carrier 40, preventing excessive movement of the positioning carrier 40 by the second cylinder 31.

[0027] See also Figure 4 As shown, the positioning seat 50 extends laterally and is provided with several supporting portions 51 for supporting the steel sheet module 302. Each supporting portion 51 is provided with a recessed portion 511 extending downward from the center and contact areas 512 located on either side of the recessed portion 511. The steel sheet module 302 contacts the contact areas 512 and not the recessed portions 511. The supporting portion 51 of the positioning seat 50 has a concave-convex design that increases the contact surface, reducing the contact area between the adhesive backing of the steel sheet module 302 and the positioning seat 50, thereby increasing the service life of the surface coating. In this embodiment, the height difference of the concave-convex design is 0.3 mm, and the contact area ratio between the contact area 512 and the adhesive backing of the steel sheet module 302 is approximately 40%.

[0028] The positioning seat 50 also features a ceramic coating applied to the contact area 512. Compared to existing silicone release coatings and Teflon coatings, the ceramic coating of the present invention offers advantages such as anti-stick properties, high wear resistance, high hardness, excellent compatibility, and excellent stability. Furthermore, the support portion 51 is equipped with an air intake hole 513 for absorbing the steel sheet module 302 and a guide surface 514 located at the longitudinal rear end. The air intake hole 513 has a diameter of 1.5 mm and provides secondary air intake for positioning after the steel sheet module 302 enters the positioning seat 50 and the baffle 61. The guide surface 514 is located on the contact area 512 and extends longitudinally from front to back, sloping downward to guide the steel sheet module 302 into the positioning seat 50.

[0029] In the present invention, the second workbench 200 also includes a positioning mechanism 60 located at the longitudinal rear end, and the positioning mechanism 60 includes a baffle 61 located below and moving vertically. When the positioning seat 50 carrying the adhesive and the steel sheet returns to its initial position, the baffle 61 moves vertically upward to between the conveyor belt 11 and the positioning seat 50, and the positioning seat 50 moves longitudinally backward until it abuts against the front end surface of the baffle 61. At this time, the adhesive and the steel sheet abut against the front end surface of the baffle 61 together, so that the adhesive and the steel sheet form a coplanar steel sheet module 302, so that the finally formed steel sheet module 302 has high positioning accuracy, high yield and high production efficiency.

[0030] In summary, the above are merely preferred embodiments of the present invention and should not be used to limit the scope of the present invention. That is, any simple equivalent changes and modifications made according to the claims and description of the present invention should still fall within the scope of the patent of the present invention.
