[0038] When the positioning mechanism of the present application is used to clamp and fix the product 800, the product 800 is first moved to the desired stop position. After the product 800 is moved to the desired stop position, the multiple clamping bodies 111 of the present application respectively apply clamping forces to different surfaces of the product 800 in the direction of approaching each other, and the pressing head 121 applies pressing force to the product 800.

After the product 800 is moved to the desired stop position, the two clamping bodies 111 of the present application are moved in a first preset direction toward each other until the two clamping bodies 111 respectively apply a preset clamping force to two opposite surfaces on the product 800. At the same time, the pressing head 121 is moved in a second preset direction toward the direction close to the product 800 until the pressing head 121 applies a pressing force to the surface of the product 800 adjacent to the surface clamped by the clamping body 111, so that the product 800 can be clamped and fixed more stably between the two clamping bodies 111 and the pressing head 121. In addition, in order to enable the pressing member 120 to quickly complete the operation of pressing the product 800 and separating from the product 800, the pressing head 121 is usually a vacuum suction cup with a matching air pipe.

In other embodiments, the second driving body 123 can also be a driving motor or a driving motor.

[0043] When the pressing head 121 in the present application needs to press the product 800, first, the second driving body 123 drives the first driving body 122 and the pressing head 121 to rotate on a preset plane until the projection pattern of the pressing head 121 can fall on the contact surface of the product 800, and then the first driving body 122 drives the pressing head 121 to move in a direction close to the product 800 until the pressing head 121 contacts the contact surface of the product 800 and applies pressing force to the product 800; when the pressing head 121 in the present application needs to be separated from the product 800, first, the first driving body 122 drives the pressing head 121 to move in a direction away from the product 800, and then the second driving body 123 drives the first driving body 122 and the pressing head 121 to rotate on a preset plane until the projection pattern of the pressing head 121 no longer falls on the contact surface of the product 800, so as to avoid interference between the pressing head 121 and subsequent products 800 and ensure that the subsequent products 800 can be processed normally.

In other embodiments, the pressing member 120 can also be directly connected to the corresponding clamping body 111. The two pressing members 120 not only further improve the stability of the product 800 at the desired resting position, but also can press and fix products 800 of different specifications, thereby expanding the application scope of the positioning mechanism.

The support frame 160 is usually detachably mounted on the positioning guide rail 140 by connecting bolts. The shape of the support frame 160 is generally L-shaped to facilitate supporting the product 800. The design of a preset gap between the clamping body 111 and the support frame 160 avoids interference of the support frame 160 with the clamping body 111. The set support frame 160 not only plays a supporting role, but also plays a positioning role, so that the two clamping bodies 111 can quickly and accurately clamp and fix the product 800 mounted on the support frame 160.

[0050] Reference Figure 3 as well as Figures 6 to 8 In one embodiment, the number of the support frames 160 is two, and the two support frames 160 are arranged at intervals along the first preset direction.

[0059] When the product 800 moves to the desired stop position, the receiving detection member 620 will not be able to receive the detection signal emitted by the transmitting detection member 610. At this time, the receiving detection member 620 will feedback the corresponding command signal to the controller. The controller issues corresponding command signals to the first driving body 122, the second driving body 123, the positioning driving member 150, the first driving part 400 and the second driving part 500 according to the actual specifications of the product 800, so that the two clamping bodies 111 can accurately clamp and fix the product 800.

The specific structure of the film-tearing mechanism 700 is common knowledge to those skilled in the art and will not be elaborated in detail here.

[0062] In summary, the implementation of the positioning mechanism and film tearing device provided in this embodiment has at least the following beneficial technical effects: when the positioning mechanism of this application is used to clamp and fix the product 800, the product 800 is first moved to the desired stop position. After the product 800 is moved to the desired stop position, the multiple clamping bodies 111 in this application respectively apply clamping forces to different surfaces on the product 800 in the direction of approaching each other, and the pressing head 121 applies pressing force to the product 800. At this time, the product 800 will be stably clamped and fixed between the multiple clamping bodies 111 and the pressing head 121. By using the clamping member 110 and the pressing member 120 in this application, the product 800 is prevented from being offset during the processing, ensuring the smooth progress of the processing operation. In addition, the multiple clamping bodies 111 are also convenient for clamping and fixing products 800 of different specifications, thereby expanding the scope of application of the positioning mechanism; by using the pressing head 121 to press and fix the product 800, the stability of the product 800 at the required rest position is enhanced, further avoiding the deviation of the product 800 during the processing; the design that the pressing head 121 can be separated from the product 800 is also conducive to the pressing head 121 to press the subsequent product 800.

[0063] The above are only preferred implementation modes of the present application, but the protection scope of the present application is not limited thereto. It should be pointed out that for those skilled in the art, several equivalent obvious variations and / or equivalent replacement modes can be made without departing from the technical principles of the present application, and these obvious variations and / or equivalent replacement modes should also be regarded as the protection scope of the present application.
