The transverse block 42 is slidably mounted on the frame 10, and the support base 43 is slidably mounted on the transverse block 42.

[0027] In one embodiment, the second alignment component 40 further includes a first fastener 47 and a second fastener (not shown in the figure). The first fastener 47 passes through the first groove 433 and is used to fix the substrate portion 432 and the first pressure plate 44. The second fastener passes through the second groove and is used to fix the substrate portion 432 and the second pressure plate 45. The second alignment component 40 also includes a first buffer pad 48 and a second buffer pad (not shown in the figure). The first buffer pad 48 is installed at the bottom of the first pressure plate 44, and the second buffer pad is installed at the bottom of the second pressure plate 45. Both the first buffer pad 48 and the second buffer pad are used to abut against the film. Optionally, both the first buffer pad 48 and the second buffer pad are dust-free cotton, which corrects the position of the film through friction.

[0028] like Figure 1 and Figure 2As shown, the second alignment component 40 further includes a slide rail 49 and a slider 41a. The slide rail 49 is mounted on the support base 43, and the slider 41a slides on the slide rail 49. The camera 46 is mounted on the slider 41a for position adjustment. Optionally, the slide rail 49 is mounted on the support portion 431. In one embodiment, the second alignment component 40 further includes a fixing plate 42a and a light source 43a.

In one embodiment, there are two sliders 41a, one camera 46, one fixing plate 42a, and one light source 43a. The two sliders 41a slide on both ends of the slide rail 49 respectively. Marking points are provided at both ends of the film.

[0029] like Figure 1 As shown, the second alignment assembly 40 further includes a lateral movement force element (not shown) and a lifting power element 44a. The lateral movement force element is mounted on the frame 10 and is used to drive the lateral movement block 42 to slide. The lifting power element 44a is mounted on the lateral movement block 42 and is used to drive the support base 43 to slide. Optionally, both the lateral movement force element (not shown) and the lifting power element 44a are motors, which is prior art.

[0030] The automatic alignment and bonding device 100 for acrylic sheets and films also includes a controller (not shown), a first position sensor (not shown), and a second position sensor (not shown). Both the first and second position sensors are used to sense the acrylic sheet. The first position sensor is mounted on a bracket 21 and corresponds to a first alignment station. The second position sensor is mounted on a machine base 41 and corresponds to a second alignment station. Optionally, both the first and second position sensors are infrared sensors, which is existing technology. The conveyor belt 22, the first sliding power element 35, the second sliding power element 36, the camera 46, the light source 43a, the lateral movement power element, the lifting power element 44a, the first position sensor, and the second position sensor are all signal-connected to the controller. The camera 46 identifies the actual position of the marking points on the film. The controller controls the movement of the lateral block 42 based on the deviation between the actual position and the preset position of the marking points, so that the actual position of the marking points corresponds to the preset position, which is existing technology.

[0031] In operation, an acrylic sheet with adhesive film attached (the film and acrylic sheet are initially bonded and not precisely aligned; the acrylic sheet is coated with UV adhesive) is placed on conveyor belt 22. Conveyor belt 22 transports the acrylic sheet with adhesive film to the first alignment station. At this point, conveyor belt 22 stops transporting the acrylic sheet, and the first sliding power element 35 drives the first sliding plate 31 to move closer to the support 21. Simultaneously, the second sliding power element 36 drives the second sliding plate 32 to move closer to the support 21, thereby aligning the acrylic sheet and ensuring that the two sides of the film are aligned with the two sides of the acrylic sheet. Then, conveyor belt 22 continues transporting the acrylic sheet towards machine 41 until the acrylic sheet reaches the second alignment station. At this point, conveyor belt 22 stops transporting the acrylic sheet, the vacuum pump starts, and the machine... 41. The acrylic sheet is adsorbed, and the lifting power element 44a drives the support base 43 to descend until the first buffer pad 48 and the second buffer pad abut the film. The camera 46 identifies the actual position of the marking point on the film. The controller controls the movement of the transverse block 42 according to the deviation between the actual position of the marking point and the preset position, so that the actual position of the marking point corresponds to the preset position. At this time, the two ends of the film are aligned with the two ends of the acrylic sheet, achieving alignment. Moreover, when the first buffer pad 48 and the second buffer pad abut the film, a certain pressure is applied to press the film onto the acrylic sheet. Finally, the support base 43 rises, the air pump stops pumping air, and the conveyor belt 22 continues to convey the aligned and bonded acrylic sheet to the UV machine for irradiation.

[0032] The automatic alignment and bonding device 100 for acrylic sheets and films of this invention aligns the two sides of the acrylic sheet and film by means of the cooperation of the first sliding plate 31 and the second sliding plate 32. Then, the acrylic sheet is adsorbed by the machine base 41, and with the cooperation of the transverse block 42 and the support base 43, the first pressure plate 44 and the second pressure plate 45 drive the film to move along the acrylic sheet, so that the two ends of the film are aligned with the two ends of the acrylic sheet, thereby realizing automatic alignment and bonding and improving production efficiency.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
