Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] The terms "first", "second", etc. in the specification and claims of the present utility model are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the utility model can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0046] In the following, in conjunction with the accompanying drawings, a film tape transfer device provided by an embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0047] like Figure 1 As shown, a film tape transfer device provided by an embodiment of the utility model mainly includes three parts: a photographing component 400, an adsorption component 500 and a transfer mechanism 600. Each part will be described in detail below:

[0048] A photographing component 400, wherein the photographing component 400 is used to take a photograph of the film tape 300 on the first placing plane 100, and to process the image obtained by taking the photograph to obtain position information of the film tape 300 on the first placing plane 100,

[0049] In this embodiment, the photographing component 400 can be an existing image acquisition device, such as a camera or a binocular stereoscopic vision depth camera, etc. Of course, a video acquisition device can also be used to record the video image of the first plane, and an image of the film tape 600 placed on the first placing plane can be obtained by intercepting a frame of the video image captured by the video acquisition device.

[0050] In this embodiment, the first resting plane 100 refers to a plane for carrying the film tape 300 . The first resting plane may be a processing platform for processing the film tape in the lamination process.

[0051] In this embodiment, the position information refers to information used to calibrate the position and placement angle of the film tape in the first plane.

[0052] The adsorption component 500 is used to adsorb or release the film tape 300 .

[0053] The transfer mechanism 600 is provided with a moving component 610 for driving the adsorption component 500 to move along a preset direction and a rotating component 620 for driving the adsorption component 500 to rotate. The transfer mechanism 600 is used to adjust the moving component 610 and the rotating component 620 according to the position information so that the adsorption component 500 adsorbs the film tape from the first shelf plane 100 and moves it to the second shelf plane and then releases it;

[0054] The height adjustment component 700 is used to adjust the distance of the adsorption component 500 relative to the first resting plane 100 and the second resting plane 200 in the vertical direction.

[0055] It should be noted that Figure 1 In order to avoid obstruction of components, the height adjustment component 700 is not shown. The height adjustment component 700 can adjust the distance of the adsorption component 500 relative to the two planes. Specifically, the adsorption component 500 is adjusted to fit the plane before adsorbing or releasing the film tape, and during the movement, it is adjusted to a specific distance from the plane.

[0056] In this embodiment, the second shelf plane 200 is similar to the first shelf plane 100 in that both are planes for carrying the film tape 300. Unlike the first shelf plane 100, the second shelf plane 200 is a plane for carrying the film tape 300 after the film tape 300 is moved. In the specific implementation process, the first shelf plane 100 and the second shelf plane can be operating platforms used for two operations sequentially performed on the film tape 300 during the lamination process. The first shelf plane 100 can be an operating platform corresponding to the previous operation, and the second shelf plane 200 can be an operating platform corresponding to the subsequent another operation.

[0057] The film tape transferring device of the present embodiment uses a photographing component to capture an image of the film tape placed on a first placing plane, and then obtains the position information of the film tape by processing the image, and then uses a transferring mechanism with a moving component and a rotating component to drive the transferring mechanism of the adsorption component to adsorb the film tape from the first placing plane, and then releases the film tape to the second placing plane through a releasing component after moving to the second placing plane. The film tape is accurately grasped and placed with the help of the photographing component, and the relative distance between the adsorption component and the plane is adjusted with the help of the height adjustment component. The whole process does not require human intervention, and can realize automatic movement of the film tape with high accuracy.

[0058] For some possible implementations, see Figure 2 As shown, the moving component 610 includes: a first moving component 611 and a second moving component 612;

[0059] The first movable component 611 is configured to drive the adsorption component to move in a first direction, the second movable component 612 is configured to drive the adsorption component to move in a second direction, the rotating component 620 drives the adsorption component 500 to rotate along a plane formed by the first direction and the second direction, the rotating component 620 is fixed on the second movable component 612, and the second movable component 612 is fixed on the first movable component 611, wherein the first direction and the second direction are perpendicular to each other.

[0060] The film tape transfer device of this embodiment is provided with a first movable component and a second movable component which move respectively in two directions perpendicular to each other. The rotating component is fixed on the second movable component to drive the rotating component to move in one direction, and then the second movable component is fixed to the first movable component to drive the rotating component to move in another direction. In addition, the rotating component drives the adsorption component to rotate in the plane formed by the first direction and the second direction, thereby providing multiple degrees of freedom for the adsorption component, thereby accurately adsorbing the film tape.

[0061] For some possible implementations, see Figure 3 As shown, the first moving assembly 611 includes: a first driving motor 6111, a first belt 6112, a first screw rod 6113, and a first slider 6114;

[0062] The output shaft of the first drive motor 6111 is arranged in parallel with the first screw rod 6113, and the output shaft of the first drive motor 6111 is connected to the end of the first screw rod 6113 through the first belt 6112, and the first slider 6114 is sleeved on the first screw rod 6113 and connected through threads.

[0063] The film tape transfer device of this embodiment drives the first screw rod to rotate by the rotation of the first driving motor, so that the first slider threadedly connected to the first screw rod can move along the direction where the first screw rod is located. The special structure of the first moving component drives the adsorption component to move along the direction where the first screw rod is located, thereby accurately assisting the adsorption component to complete the adsorption or release operation.

[0064] For some possible implementations, see Figure 4 As shown, the second moving assembly 612 includes: a first connecting rod 6121, a second driving motor 6122, a second belt 6123, a second screw rod 6124, and a second slider 6125;

[0066] Preferably, in order to ensure the stability of the movement of the second moving assembly during the specific implementation, a plurality of first connecting rods 6121 may be arranged in a symmetrical structure to fix the second driving motor and the first sliding block;

[0067] The output shaft of the second drive motor 6122 is arranged in parallel with the second screw rod 6124, and the output shaft of the second drive motor 6122 is connected to the end of the second screw rod 6124 through the second belt 6123, and the second slider 6125 is sleeved on the second screw rod 6124 and connected through threads.

[0068] The film tape transfer device of this embodiment drives the second screw rod to rotate by rotating the second drive motor, so that the second slider threadedly connected to the second screw rod can move along the direction of the second screw rod. The special structure of the second moving component is used to drive the adsorption component to move in the direction of the second screw rod, further accurately assisting the moving adsorption component to complete the adsorption or release operation.

[0069] In some possible implementations, please combine again Figure 3 As shown, the height adjustment assembly 700 includes: a slide rail 710 and a third slider 720;

[0070] The slide rail 710 is arranged along the vertical direction, the third slider 720 moves along the slide rail 710, and the end of the first screw rod 6113 away from the first drive motor 6111 is fixed to the third slider 720. In a specific implementation, the slide rail 710 can be fixed to a specific fixing mechanism, for example, the slide rail is fixed to a wall or a fixed bracket, and the track of the slide rail is arranged to be along the vertical direction.

[0071] The film tape transfer device of this embodiment realizes height adjustment of the adsorption component through the cooperation of the slide rail and the third slider arranged in the vertical direction. Specifically, the third slider is used to directly drive the first movable component to move in the vertical direction, and the height adjustment of the adsorption component is indirectly driven by the connection relationship between the adsorption component and the first movable component, thereby increasing the degree of freedom of the movable component in the vertical direction and further improving the flexibility of the film tape movement.

[0072] For some possible implementations, please continue to refer to Figure 4 As shown, the rotating assembly 620 includes: a second connecting rod 621 and a third driving motor 622;

[0073] The output shaft of the third drive motor 622 is perpendicular to the output shaft of the first drive motor 6111 and the output shaft of the second drive motor 6122. The third drive motor 622 is fixedly connected to the second slider 6125 via a second connecting rod 621. The adsorption assembly 500 is fixed on the output shaft of the third drive motor 622.

[0074] Preferably, in order to ensure the stability of the movement of the rotating assembly during the specific implementation, a plurality of second connecting rods 621 may be provided in a symmetrical structure to fix the third driving motor 622 and the second sliding block 6125 .

[0075] The film tape transfer device of this embodiment drives the adsorption component to rotate within a plane through the rotation of the third driving motor, thereby adjusting the direction of the adsorption component and further accurately moving the adsorption component to complete the adsorption or release operation.

[0076] For some possible implementations, please continue to refer to Figure 4 As shown, the rotating assembly 620 further includes: a reducer 623 and a flange 624;

[0077] The reducer 623 is connected to the output shaft of the third driving motor 622 , and the flange 624 is used to connect the adsorption assembly 500 and the reducer 623 .

[0078] The film tape transfer device of this embodiment realizes the control of the rotation of the adsorption component by setting a reducer on the output shaft of the third drive motor that drives the adsorption component to rotate, which facilitates more precise control of the angle of the adsorption component relative to the film tape and helps to improve the accuracy of controlling the moving direction of the film tape.

[0080] The body of the vacuum suction cup 510 is arranged toward the first resting plane 100 or the second resting plane, and an air pipe joint 520 is arranged on the side of the vacuum suction cup 510 away from the first resting plane 100 or the second resting plane, one end of the air pipe is connected to the air pipe joint 520, and the other end of the air pipe is connected to the vacuum pump.

[0081] The film tape transfer device of this embodiment connects the vacuum suction cup with the vacuum pump through an air pipe, and realizes the automatic discharge and recovery of air in the vacuum suction cup by controlling the vacuum pump, so that the adsorption component can automatically adsorb or release the film tape without the aid of external force, further improving the degree of automation of moving the film tape and reducing production costs.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
