Fig. 1 is an exploded schematic view of a positioning device according to an embodiment of the present invention. As shown in fig. 1, the positioning device provided in this embodiment includes a frame 1, a table 2, a cam 3, a top plate 4, a positioning column 5, a driving assembly 6, and a guide mechanism 7. Wherein the guiding mechanism 7 comprises a guiding stud 71 and a sleeve 72.

Specifically, as shown in fig. 4, the rack 1 includes a bottom plate 11, a first side plate 12, and a second side plate 13. The first side plate 12 and the second side plate 13 are two identical rectangular plates, and the first side plate 12 and the second side plate 13 are relatively fixedly arranged on the rectangular bottom plate 11. The first side plate 12 and the second side plate 13 have a through hole 121 and a through hole 131 at the geometric centers thereof, respectively. The through-

holes

121 and 131 are used to mount the driving assembly 6. More specifically, the base plate 11 has a mounting hole 111 for mounting the guide mechanism 7.

As shown in fig. 5, a plurality of products having different shapes are placed on a square plate-shaped table 2. The worktable 2 is provided with positioning holes 21, and the positioning holes 21 are distributed on four sides of the worktable 2. The outer side of each product has two positioning holes 21. The positioning hole 21 is used for positioning the adhesive film.

As shown in fig. 6, the top plate 4 having a square plate shape has a mounting hole 42 provided to face the positioning hole 21. The positioning column 5 is fixedly installed on the top plate 4 through the installation hole 42. The top plate 4 also has a through guide hole 41.

Referring to fig. 2 and 3, the guide post 71 is fixedly mounted on the base plate 11 through the mounting hole 111, and the sleeve 72 is movably fitted over the guide post 71. The pipe sleeve 72 is fixedly connected with the top plate 4 through the guide hole 41. In which the socket 72 is linearly reciprocated with respect to the guide post 71, the top plate 4 fixedly connected to the socket 72 is defined to be linearly reciprocated in the same manner.

In this embodiment, the driving assembly 6 includes a power mechanism 61 and a rotating shaft 62. The rotary shaft 62 is rotatably provided on the housing 1 through the through

holes

121, 131. Further, the power mechanism 61 includes a handle bar 611 and a shaft sleeve 612, wherein the shaft sleeve 612 is fixedly sleeved on one end of the rotating shaft 62, and the handle bar 611 is fixedly connected with the shaft sleeve 612. The rotation shaft 62 is rotated by rotating the lever 611. It should be understood that the power mechanism 61 may also be used with other devices capable of controlling the rotation of the rotating shaft 62, such as a motor.

In this embodiment, the table 2 is fixedly provided on the top of the frame 1, and the top plate 4 is provided below the table 2 in a movable manner with respect to the frame 1.

Further, as shown in fig. 7, the circumferential surface of the cam 3 in the present embodiment includes a curved surface b and a flat surface a. The cam 3 is fixedly connected with the rotating shaft 62 through a cylindrical pin 8 and is arranged below the top plate 4. It should be understood that the cam 3 and the shaft 62 may be connected by other than a pin connection, such as a key connection. The circumferential surface of the cam 3 is in contact with the bottom surface of the top plate 4.

Specifically, the rotating lever 611 is rotated to rotate the rotating shaft 62 to rotate the cam 3, and the curved surface b and the plane a of the cam 3 alternately contact the bottom surface of the top plate 4. More specifically, when the flat surface a of the cam 3 contacts the bottom surface of the top plate 4, the top plate 4 is located at the lowest position, and the positioning column 5 does not protrude from the upper surface of the table 2. When the curved surface b of the cam 3 contacts the bottom surface of the top plate 4, the top plate 4 is located at the highest position, and the positioning column 5 extends out of the upper surface of the workbench 2.

In this embodiment, the number of the cams 3 is two, so that the top plate 4 is stressed more uniformly, and the top plate 4 can perform linear reciprocating motion more stably. It should be understood that the number of the cams 3 may be one, three, etc., and is not particularly limited.

For the embodiment, the adhesive film is adapted to the product, and the adhesive film is covered with a removable adhesive film, and the adhesive film is provided with a hole corresponding to the positioning hole 21. The operator shakes the lever 611 to rotate the rotating shaft 62, thereby rotating the cam 3. As shown in fig. 8, when the cam 3 rotates until the curved surface b contacts the bottom surface of the top plate 4, that is, the cam 3 pushes up the top plate 4, so that the positioning column 5 extends out of the upper surface of the table 2. At the moment, an operator puts the product into a corresponding position on the workbench 2, the hole of the adhesive film is aligned to the positioning column 5, and the adhesive film is placed on the product in a proper position after positioning, so that the butt joint of the adhesive film and the product is accurate. The operator then rocks the lever 611 again to bring the flat surface a of the cam 3 into contact with the bottom surface of the top plate 4. As shown in fig. 9, at this time, the positioning column 5 is retracted into the workbench, and the operator can roll from one side of the film to the other side by using the roller with soft silica gel, attach the film to the product, and discharge the air bubbles inside. Finally, the mucosa is removed from the sticking film, and the sticking film work is completed.

This embodiment makes the reference column on the roof stretch out the workstation surface through setting up the cam under the roof, realizes the locate function to placing the pad pasting on the workstation, need not the manual work and aligns, and it is more accurate to paste the position, and the uniformity is good. After the positioning is completed, the positioning column retracts through the cam, the film pasting is facilitated, and the efficiency is improved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
