Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive lamination, and particularly relates to a positioning tooling for adhesive lamination. Background Technique

[0002] In the production line of product assembly, pasting adhesive on the assembled product is a common operation means. For example, adhesive auxiliary materials are pasted on the inner side of the mobile phone case to play a role in sealing, waterproofing and dustproofing.

[0003] Publication No.: CN220163259U, discloses: an extrusion lamination adhesive device. By placing the product shell in the positioning groove, both sides are limited by the limiting rods. Rotating the first lead screw can drive the displacement of the limiting rods for horizontal adjustment. Rotating the second lead screw can adjust the positioning plate back and forth, and the guide rail is used for guiding to realize the positioning and position adjustment of the product shell.

[0004] In the specific implementation process of the above-mentioned prior art, the following disadvantages still exist:

[0005] It is necessary to manually adjust the first lead screws on both sides to drive the corresponding limiting rods to move in order to achieve the purpose of limiting the left and right ends of the product shell. The operation is relatively cumbersome, and the displacement length of the limiting rods on both sides cannot be controlled. It is easy to have different displacement lengths of the limiting rods on both sides, causing the product shell to deviate from the center position, resulting in the deviation of the lamination position and poor positioning effect. At the same time, there is no corresponding positioning mechanism on the front and rear sides of the product shell, so it is impossible to ensure that the product shell is located at the center position, affecting the positioning effect of the product shell.

[0006] In view of the above problems, we propose a positioning tooling for adhesive lamination. Content of the Utility Model

A positioning groove is opened at the top of the base, and a through groove penetrates through the bottom of the positioning groove. A threaded rod is arranged below the through groove, and two movable blocks are threadedly arranged on the threaded rod and are movably matched with the through groove. On the side of the tops of the two movable blocks close to each other, a limiting block is fixed. Two guiding grooves penetrate through both sides of the through groove, and a front and rear positioning assembly is slidably arranged in the guiding grooves. On the front and rear sides of the movable block, a strip-shaped plate is fixed, and a strip-shaped hole penetrates through the strip-shaped plate and is matched with the front and rear positioning assembly. On the side of the two limiting blocks close to each other, an installation groove is opened, and a contact sensor is installed in the installation groove. A lamination assembly is arranged at the rear of the base.

[0009] The front and rear positioning components include a support rod, a guide block, a rubber column and a movable rod. The support rod is fixed inside the guide groove. The guide block is slidably sleeved on the support rod. The rubber column is rotatably installed on one side of the top of the guide block through a rotating shaft.

[0010] A fixed plate is fixed inside the through groove. A support plate is movably arranged on the upper side of the fixed plate. A number of piston rods are movably arranged on the fixed plate. The upper ends of the piston rods are fixedly connected to the support plate. A circular plate is fixed at the lower end of the piston rod. A return spring is connected between the circular plate and the fixed plate, and the return spring is sleeved outside the piston rod.

[0011] A number of support legs are fixed at the bottom of the base, and rubber pads are fixed at the lower ends of the support legs.

[0012] Two vertical plates are relatively fixed at the bottom of the base. The threaded rod is rotatably arranged between the two vertical plates. A motor is installed on the outer side of the left vertical plate, and the output end of the motor is connected to the left end of the threaded rod.

[0013] A fixed rod is arranged below the threaded rod. The fixed rod is fixed between the two vertical plates, and the fixed rod penetrates through the movable block.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The utility model facilitates the placement of the product housing through the positioning groove. Among them, under the screw thread fit between the threaded rod and the movable block, combined with the movable fit between the movable block and the through groove, it is convenient to adjust the two movable blocks to approach each other until the limiting block is driven to approach the product housing placed in the positioning groove. Cooperating with the contact sensor to control the moving distance of the limiting block, the left and right ends of the product housing are limited, solving the problem in the prior art that the first lead screws on both sides need to be manually adjusted to drive the corresponding limiting rods to move in order to limit the left and right ends of the product housing.
