DETAILED DESCRIPTION

[0022] In order to make the purpose, principle and structure of the present invention more clear, it is further described below with reference to the accompanying drawings and specific embodiments.

[0023] See also Figures 1 to 8 The utility model provides a film paper secondary precision positioning mechanism, including: a film paper taking mechanism, a film paper precision positioning adjustment mechanism and a film paper 4.

[0024] The film paper removal mechanism includes: a film suction positioning plate 3 arranged at the bottom, wherein the film suction positioning plate 3 is provided with a plurality of through holes, a plurality of precise positioning holes 15 and a plurality of air ducts, and a plurality of vacuum pumps 11 are provided on the side of the film suction positioning plate 3, and the vacuum pumps 11 are connected to the air ducts. Through negative pressure extraction, the film paper 4 can be adsorbed under the film suction positioning plate 3 under the action of vacuum negative pressure. It also includes a top plate 9 arranged above the film suction positioning plate 3, and the top plate 9 is connected to the film suction positioning plate 3 by a plurality of springs 10 and plays a buffering role. The springs can also be provided with guide rollers for strengthening the limit. It also includes a positioning cylinder 1 vertically arranged on the upper part of the film suction positioning plate 3, and the bottom extension of the positioning cylinder 1 is provided with a positioning pin 2, and the positioning pin 2 passes through the film suction positioning plate 3 through the through hole. The film paper 4 is provided with a plurality of auxiliary positioning holes, and the aperture of the auxiliary positioning hole is the same as the diameter of the positioning pin 2. The top of the positioning pin 2 is provided with a conical guide surface 13. Driven by the positioning cylinder 1, the positioning pin 2 can move up and down. During the downward movement, the positioning pin 2 can pass through the auxiliary positioning hole of the film paper 4. The tapered guide surface 13 on the positioning pin 2 can correct the deviation of the film paper 4. The specific principle is that the conical surface has an inclined angle, so the contact area of ​​the film paper 4 with the conical surface is extremely small. The downward movement of the positioning pin 2 can bring about greater pressure, so the pressure on the contact surface between the film paper 4 and the conical surface is relatively high. This pressure can overcome the vacuum pressure and friction between the film paper 4 and the film suction positioning plate 3 to achieve deviation correction. In addition, the conical surface is geometrically symmetrical, which can guide and correct deviations in multiple directions.

[0025] The film paper precision positioning adjustment mechanism includes: an adjustment positioning plate 6 arranged at the top, wherein the adjustment positioning plate 8 is provided with a plurality of air passages, a plurality of positioning holes 7, and a plurality of through holes, and a plurality of vacuum pumps are provided at the lower end of the adjustment positioning plate 8. The vacuum pumps are connected to the air passages to achieve vacuum negative pressure adsorption of the film paper 4 by the upper surface of the adjustment positioning plate 8. It also includes a frame structure 12 arranged below the adjustment positioning plate 6 and fixedly connected thereto, wherein a precise positioning cylinder 8 is provided at the bottom of the frame structure 12, wherein the upward extension of the precise positioning cylinder 8 is provided with a base plate, and a plurality of precise positioning pins 5 are vertically provided on the base plate. The precise positioning cylinder 8 can drive the base plate to move up and down, and the up and down movement of the base plate can drive the precise positioning pins 5 to move up and down. The precise positioning pins 5 pass through the through holes of the adjustment positioning plate 6 and extend into the precise positioning holes 15 of the film suction positioning plate 3. The precise positioning holes 15 and the through holes of the adjustment positioning plate 6 are both provided with guide sleeves 14, and the inner diameter of the guide sleeves 14 matches the radius of the precise positioning pins 5. The film paper 4 is also provided with a plurality of auxiliary positioning holes that cooperate with the precise positioning pins 5 .

[0026] When the positioning pin 2 moves downward, it passes through the auxiliary positioning hole on the film paper 4 and then extends into the positioning hole 7 of the adjustment positioning plate 6. The inner diameter of the positioning hole 7 matches the size of the positioning pin 2.

[0027] The specific workflow is as follows:

[0028] Start the vacuum pump 11 of the film suction positioning plate 3 to suck the film paper 4 underneath, and move the film suction positioning plate 3 to the top of the adjustment positioning plate 6. Drive the positioning cylinder 1 to push the positioning pin 2 downward. The positioning pin 2 continues to move downward through the auxiliary positioning hole of the film paper 4 and then extends into the positioning hole 7 to form positioning and limit.

[0029] The film suction positioning plate 3 is moved downward until the lower surface of the film suction positioning plate 3 is in slight contact with the upper surface of the adjustment positioning plate 6 , at which time the spring 10 can play a buffering role.

[0030] The precise positioning pin 5 moves upward under the driving action of the precise positioning cylinder 8, passes through the auxiliary positioning hole on the film paper 4 and then extends into the precise positioning hole 15 in the film suction positioning plate 3 to form a limit. At this time, the positioning pin 2 and the precise positioning pin 5 both limit the film paper 4.

[0031] The vacuum pump 11 of the film suction positioning plate 3 is turned off, releasing the film paper 4 from its suction. The vacuum pump of the adjustment positioning plate 6 is activated, and the film paper 4 is adsorbed onto the adjustment positioning plate 6. During the process of releasing the negative pressure, naturally falling, and then adsorbing the negative pressure, the film paper 4 continuously moves vertically along the positioning pins 2 and the precision positioning pins 5, without any lateral positional deviation, thus achieving the invention's purpose of precisely positioning the film paper 4.

[0032] The positioning pin 2 and the precise positioning pin 5 are retracted and withdrawn from the auxiliary positioning hole of the film paper 4, and the film suction positioning plate 3 is lifted and transferred to the next station. At this point, the whole process of the operation is completed.

[0033] The above description is only a specific implementation method of this utility model, but the protection scope of this utility model is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by this utility model, can make equivalent substitutions or changes based on the technical solutions and new concepts of this utility model, which should be covered by the protection scope of this utility model.
