Detailed Implementation

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, an embodiment of this application discloses a Mylar attachment assembly, including a Mylar feeding mechanism 1. A fixture 2 for placing a PCB board is provided on one side of the Mylar feeding mechanism 1. A robot arm 3 is provided between the fixture 2 and the feeding mechanism. A suction attachment mechanism 4 is provided at the drive end of the robot arm 3. The suction attachment mechanism 4 is used to pick up the Mylar at the Mylar feeding mechanism 1 and attach it to the PCB. The suction and attachment mechanism 4 includes a suction component, a smoothing component for smoothing the attached Mylar end on one side of the suction component, and a first positioning camera 41 disposed on one side of the suction component.

[0022] During the actual attachment process, the robotic arm 3 first moves to the Mylar feeding mechanism 1 and uses the suction component to pick up the Mylar. After the suction is complete, the robotic arm 3 drives the suction component to transport the Mylar to the top of the PCB board for attachment. During the attachment process, the suction component slowly descends, attaching the Mylar to the surface of the PCB board, and then the smoothing component presses and smooths the tail end of the Mylar.

[0023] The aforementioned structure ensures the flatness and tightness of Mylar during the bonding process, avoiding wrinkles and bubbles common in traditional methods. Through precise adsorption of components and multi-directional smoothing motion, Mylar can evenly adhere to the PCB surface, further improving bonding quality.

[0024] In this embodiment, the suction component includes a suction block 42, the surface of which is provided with a plurality of vacuum suction holes 43, and also includes a first drive cylinder 44 for driving the suction block 42 to perform lifting and lowering movements.

[0025] Specifically, the suction block 42 moves up and down by the drive of the first drive cylinder 44, thereby completing the adsorption and release of Mylar. During the adsorption process, the vacuum suction hole 43 generates negative pressure, firmly adsorbing the Mylar onto the surface of the suction block 42. When the attachment position is reached, the vacuum suction hole 43 stops working, and the Mylar is precisely released onto the PCB board and pressed down, so that the Mylar is attached to the designated position on the PCB board.

[0026] The above design enables precise positioning and attachment of the Mylar, avoiding the offset or misalignment problems caused by improper operation in traditional methods.

[0027] In this embodiment, the smoothing mechanism includes a smoothing block 45 and a second drive cylinder 46 for driving the smoothing block 45 to move up and down.

[0028] Specifically, the robotic arm 3 drives the suction component to pick up the Mylar and attach it to the PCB, and the second drive cylinder 46 drives the smoothing block 45 to descend and press the tail end of the Mylar. The robotic arm 3 moves the smoothing block 45 to the side of the Myra tail end and presses it down. The robotic arm 3 moves the smoothing block 45 to the other side of the Myra tail end and presses it down. The robotic arm 3 moves the smoothing block 45 to the Myra tail end and presses it down and moves left and right to smooth and press the Myra tail end tightly.

[0029] Specifically, because the PCB board corresponding to the attachment point of the Mylar tail has a protrusion, the suction component cannot accurately pick up the Mylar tail and attach it to the PCB board. Therefore, after the Mylar is attached, the Mylar tail will be raised. Therefore, the smoothing mechanism presses and smooths the three sides of the Mylar tail, so that Mylar can be effectively attached even to uneven PCB boards.

[0030] In this embodiment, the suction block 42 includes a suction block 42 body, an inner groove 421 is provided in the middle of the suction block 42, a suction edge is provided around the inner groove 421, and the vacuum suction hole 43 is located on the suction edge.

[0031] Specifically, due to the protrusions on the PCB board, the design of the inner groove 421 allows the suction block 42 to avoid these protrusions when attaching Mylar, preventing the adhesion effect of Mylar from being affected by the protrusions. The setting of a suction edge ensures that the vacuum suction hole 43 can fully and evenly absorb Mylar, making the Mylar evenly stressed during the suction process and avoiding localized weak adhesion. When the suction block 42 descends and approaches the Mylar, the vacuum suction hole 43 generates suction on the suction edge, firmly adhering the Mylar to the suction edge and ensuring that the Mylar is stably absorbed. At the same time, the avoidance groove 47 set on the body of the suction block 42 enhances the adaptability of the suction block 42 to the protrusions on the PCB board. During the suction and attachment process, the avoidance groove 47 provides clearance for the protrusions, allowing the suction block 42 to fit more closely to the surface of the PCB board, thereby improving the accuracy and integrity of Mylar attachment.

[0032] In this embodiment, the absorber block 42 body is provided with a plurality of clearance grooves 47 for avoiding protrusions on the PCB.

[0033] Specifically, when the suction block 42 descends to attach the Mylar, the clearance groove 47 can precisely avoid the protrusions on the PCB, preventing the suction block 42 from colliding with the protrusions and ensuring that the Mylar can be smoothly attached to the PCB. The position and size of these clearance grooves 47 are designed according to the actual situation of the protrusions on the PCB, so as to adapt to the structural characteristics of the PCB to the greatest extent.

[0034] In this embodiment, a third drive cylinder 48 is also included for driving the smoothing block 45 to move horizontally.

[0035] Specifically, the third drive cylinder 48 can be selected and set according to actual needs. The third drive cylinder 48 can be used to adjust the horizontal position of the smoothing block 45 to better adapt to Mylar and PCB boards of different sizes and shapes. When facing Mylar attachment operations of different specifications, the third drive cylinder 48 can control the smoothing block 45 to extend or retract, ensuring effective smoothing operation of the Mylar tail end.

[0036] In this embodiment, a second positioning camera 5 is also provided between the Mylar feeding mechanism 1 and the fixture 2 for positioning the Mylar after it has been sucked up.

[0037] Specifically, after the robotic arm 3 picks up the Mylar using the suction component, it first transports the Mylar to the second positioning camera 5. The second positioning camera 5 precisely captures and analyzes the Mylar's position, angle, and other information, then feeds this data back to the control system. Based on the feedback, the control system adjusts the movement trajectory of the robotic arm 3 to ensure that the Mylar is accurately aligned with the PCB board during subsequent attachment. The positioning function of the second positioning camera 5 further improves the accuracy of Mylar attachment and reduces attachment defects caused by Mylar positional deviations.

[0038] In this embodiment, the fixture 2 includes a fixture body 21, on which a plurality of vacuum suction cups 22 are provided, and a clamping component 23 for clamping the PCB board is also provided on the fixture body 21.

[0039] Specifically, after the PCB board is loaded onto the fixture body 21, the vacuum suction cup 22 generates suction to firmly adhere the PCB board to the fixture body 21, ensuring that it will not shift during the attachment process. Next, the clamping component 23 rotates and presses against the PCB board to clamp and fix the PCB board, preventing the PCB board from shaking or tilting.

[0040] This invention also discloses a Mylar attachment method, which uses the Mylar attachment component described above, and the steps are as follows: S100: The PCB board is loaded onto fixture 2 and held in place by fixture 2; S200: The robotic arm 3 drives the suction component to pick up the Mylar and then moves the Mylar to the second positioning camera 5 to position the Mylar product. S300: The robotic arm 3 drives the suction component to move above the PCB board, the first positioning camera 41 positions the PCB board, the robotic arm 3 drives the suction component to move and attach the Mylar to the PCB, and the second drive cylinder 46 drives the smoothing block 45 to descend and press the tail end of the Mylar. S400: The robotic arm 3 moves the smoothing block 45 to the side of the Myra tail end and presses it down. The robotic arm 3 moves the smoothing block 45 to the other side of the Myra tail end and presses it down. The robotic arm 3 moves the smoothing block 45 to the Myra tail end and presses it down and moves left and right to smooth and press the Myra tail end tightly.

[0041] In the above method, the efficient and precise attachment of Mylar to the PCB board is achieved through the coordinated work of various components. In step S100, the vacuum suction cup 22 and the clamping component 23 of the fixture 2 ensure the stable fixation of the PCB board, providing a good foundation for subsequent attachment. In step S200, the positioning of the Mylar by the second positioning camera 5 allows the Mylar to be precisely adjusted in position during transportation, preparing for accurate attachment. In step S300, the first positioning camera 41 positions the PCB board, and combined with the positioning of the Mylar by the second positioning camera 5, the suction component can accurately attach the Mylar to the designated position on the PCB board. At the same time, the second drive cylinder 46 drives the smoothing block 45 to descend and press down on the tail end of the Mylar, preventing the tail end of the Mylar from lifting up. In step S400, the robotic arm 3 drives the smoothing block 45 to move in multiple directions, from one side of the Mylar tail to the other side, and then back to the tail to press down and move left and right. This operation can smooth and press the Mylar tail tightly, so that the Mylar tail can be tightly attached to the PCB board, further improving the overall quality of the attachment.

[0042] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention.
