[0025] As Figures 1 to 4 shown, a multi-station high-precision assembly mechanism for a PET assembly machine, in which this embodiment includes a frame 1, a positioning platform 2 provided on the end face of the frame 1 for placing the PET film to be bonded with conductive glue, a support frame 11 erected on the positioning platform 2, a plurality of attaching heads 3 provided on the support frame 11 for attaching conductive glue, and a CCD camera 8 provided on each attaching head 3 for accurately positioning the attaching position. A Z-axis driving component 4 for driving the support frame 11 to move in the Z-axis direction is provided on the frame 1, and an X-axis driving component 5 for driving each of the attaching heads 3 to move in the X-axis direction is provided at the top of the support frame 11. A rotation driving component 6 for driving each attaching head 3 to rotate around the Y-axis and a Y-axis driving component 7 for driving each attaching head 3 to lift in the Y-axis direction are further provided between each attaching head 3 and the support frame 11.
[0026] The frame 1 of this embodiment serves as the basic support structure of the mechanism. A positioning platform 2 is provided at the center end face on one side of the frame 1, and an adsorption component is arranged inside it, which can fix the PET film to be processed to prevent it from moving when attaching the conductive adhesive. The two support frames 11 straddle the positioning platform 2 and carry two attaching heads 3 and related driving components in this embodiment. Each attaching head 3 has a conductive adhesive of a suitable length that has been cut and prepared, and a CCD camera 8 for positioning the PET film is arranged on each attaching head 3. When the PET film to be processed is placed flat on the positioning platform 2, the specific coordinate values of each attaching point are set according to actual needs, and calibration is carried out in combination with the CCD camera 8 on the attaching head 3. The Z-axis driving component 4 moves the support frame 11 longitudinally along the Z-axis according to the target position, and the two X-axis driving components 5 on the support frame 11 can independently drive the attaching head 3 to move horizontally in the lateral direction to cut and laterally adjust the driven attaching head 3, while the Y-axis driving component 7 adjusts the vertical height of the attaching head 3 to make it close to but not touch the surface of the PET film for attaching work. If vertical or inclined attachment is required, the rotating driving component 6 can rotate the attaching head 3 around the Y-axis to make appropriate angle adjustments, enabling high-precision and automatic attachment of the conductive adhesive.
[0027] As Figure 3 shown, the attaching head 3 of this embodiment includes a carrier plate 31, a feed reel 32 arranged on the carrier plate 31 for conveying the conductive tape, a pulling roller 33 arranged on the carrier plate 31 for pulling out the conductive tape, and an attaching component 34 arranged between the feed roller and the pulling roller 33. The attaching component 34 includes a pressing groove 341 directly below the CCD camera 8, a pressing block 342 arranged in the pressing groove 341, and a pushing cylinder 343. The pushing cylinder 343 can drive the pressing block 342 to press down along the pressing groove 341 to attach the conductive adhesive. Specifically, the pulling roller 33 is connected to the feed reel 32, and by driving its rotation through the servo motor behind, a suitable length of conductive tape can be pulled out from the feed reel 32. At the same time, it can be moved to the cutting station on one side of the frame 1 through the X-axis driving component 5 to cut the conductive tape for standby; then, the attaching component 34 composed of the pressing groove 341, the pressing block 342, and the pushing cylinder 343 presses and attaches the pulled-out conductive tape. Specifically, a pressing plate is arranged on the end face of the carrier plate 31, and a pressing groove 341 corresponding to the CCD camera 8 is arranged in the middle position, and an electric cylinder is fixedly installed at the top position of the pressing groove 341 as the pushing cylinder 343, and its output end is fixedly connected to a pressing block 342 that can move along the pressing groove 341. When the conductive tape reaches the correct position and reaches above the PET film attaching position through the multi-axis movement system, the pushing cylinder 343 is activated to drive the pressing block 342 to move downward along the pressing groove 341, applying sufficient pressure to the conductive tape to make it tightly adhere to the surface of the PET film.
[0028] AsFigure 2 As shown in the figure, the X-axis drive assembly 5 of this embodiment includes an X-axis drive motor 51 provided at the top of the support frame 11, an X-axis screw rod 52 drivingly connected to the X-axis drive motor 51, an X-axis slide 53 threadedly connected to the X-axis screw rod 52, and an X-axis slide rail 54 slidably connected to the X-axis slide 53 and parallel to the X-axis screw rod 52. When the control system issues a movement command, the X-axis drive motor 51 transmits the rotational movement to the X-axis screw rod 52. As the screw rod rotates, the X-axis slide 53 threadedly connected thereto linearly moves along the X-axis slide rail 54. Thereby, it drives the attachment head 3 to perform lateral adjustment in the X-axis direction. Also, due to the high precision of the screw drive system, the attachment head 3 can accurately reach the predetermined position.
[0029] As Figure 3 and Figure 4 shown in the figure, the rotation drive assembly 6 of this embodiment includes a rotation motor 61 provided on the X-axis slide 53 and a rotation shaft 62 drivingly connected to the output end of the rotation motor 61. The attachment head 3 is connected to the rotation shaft 62. The output shaft of the rotation motor 61 of this embodiment is parallel to the Y-axis of this embodiment. The rotation shaft 62 can rotate around the Y-axis by connecting its output shaft. The rotation angle can be precisely controlled through a feedback system such as an encoder, and the attachment angle of the conductive tape can be adjusted as needed.

Both Y-axis sliders 76 are fixedly connected to the Y-axis nut seat 74. When it is necessary to adjust the height of the attachment head 3, the control system sends a command to the Y-axis drive motor 72 to drive the Y-axis screw rod 73 to rotate. Then, the Y-axis nut seat 74 linearly moves along the Y-axis screw rod 73, driving the Y-axis sliders 76 fixed on both sides thereof to move up and down along the two Y-axis slide rails 75.
[0031] As Figure 2As shown in the figure, the Z-axis drive assembly 4 of this embodiment includes a Z-axis drive motor 41 provided on the end face of the frame 1 and located on one side of the positioning platform 2, a Z-axis screw rod 42 drivingly connected to the Z-axis drive motor 41, a first Z-axis slider 43 located at the bottom of the support frame 11 and threadedly connected to the Z-axis screw rod 42, and a Z-axis slide rail 44 slidably connected to the first Z-axis slider 43 and parallel to the Z-axis screw rod 42. A second Z-axis slider 45 is further provided at the bottom of the other side of the support frame 11, and a balance guide rail 46 slidably connected to the second Z-axis slider 45 is provided on the end face of the other side of the positioning platform 2. When it is necessary to adjust the orientation in the Z-axis direction, the control system sends an instruction to the Z-axis drive motor 41 to drive the Z-axis screw rod 42 to rotate. The first Z-axis slider 43 linearly moves along the Z-axis screw rod 42, driving the support frame 11 to move along the Z-axis slide rail 44. At the same time, the second Z-axis slider 45 moves along the balance guide rail 46 to ensure that the support frame 11 remains horizontal during the movement.
[0032] In summary, the beneficial effects of this embodiment are as follows: Through the collaborative work of the CCD camera 8 and the multi-axis drive system composed of the X-axis, Y-axis, Z-axis and rotation drive assembly 6 in this embodiment, precise attachment of the conductive tape on the PET film can be achieved; and multiple attachment heads 3 are provided to improve the attachment efficiency.
