[0019] Example 1
[0020] like Figures 1 to 4As shown, this utility model provides a technical solution: an auxiliary device for bonding polycarbonate sheets inside a railway train display screen, including a mounting base 100, a positioning block 200, a support shaft 300, a mounting block 400, a telescopic cylinder 500, an extrusion plate 600, and an extrusion section 800, as follows. Figure 1 As shown, the positioning block 200 is installed at the lower end of the mounting base 100, and a rubber pad 2 is installed on the top surface of the mounting base 100. The mounting block 400 is installed above the mounting base 100 via a support shaft 300. The telescopic cylinder 500 is installed on the mounting block 400, and the extrusion plate 600 is located at the moving end of the telescopic cylinder 500. The telescopic cylinder 500 drives the extrusion plate 600 to move away from or closer to the mounting base 100 to extrude the polycarbonate sheet. After a 3-second pause, the telescopic cylinder 500 drives the extrusion part 800 to reset. The extrusion plate 600 has adjustment holes 700 at both ends, and at least two sets of extrusion parts 800 are installed on the extrusion plate 600. In this embodiment, two sets of extrusion parts 800 are used. The extrusion parts 800 are partially located within the adjustment holes 700. The extrusion parts 800 slide along the width direction of the extrusion plate 600, so that the extrusion parts 800 move closer or further away from each other, thereby realizing the extrusion of polycarbonate sheets of different sizes.
[0021] In a further embodiment, at least two sets of L-shaped limiting members 900 are also included. The L-shaped limiting members 900 have rectangular through holes 1 at both ends. The L-shaped limiting members 900 are installed on the longitudinal side of the mounting base 100 through connectors and rectangular through holes 1. The L-shaped limiting members 900 are located on both sides of the support shaft 300. When the polycarbonate sheet is placed on the mounting base 100, the L-shaped limiting members 900 limit and abut against the polycarbonate sheet.
[0022] In a further embodiment, such as Figure 4 As shown, the extrusion section 800 includes two sets of sliding members 801, which are slidably mounted opposite each other in the adjustment hole 700. Each sliding member 801 has a mounting hole 802 at its end near the extrusion plate 600. A fastener is installed in the mounting hole 802, which limits and fixes the sliding member 801 to a predetermined position on the extrusion plate 600. The fastener can be a bolt 807, but is not limited to bolt 807. Each sliding member 801 has a placement hole 803 in the transverse direction. A pressure member is installed between the sliding members 801. The pressure member includes two sets of insertion rods 804, which are inserted into the placement hole 803. A pressure rod 805 is installed between the insertion rods 804, and an elastic layer is installed on the surface of the pressure rod 805 near the mounting base 100.
[0023] Through the above technical solution, this utility model can achieve the following working process:
[0024] Based on the size of the polycarbonate sheet, adjust the distance between the sliding parts 801, and use fasteners to limit the sliding parts 801 to a specified position on the extrusion plate 600 so that the distance between the pressing parts is the same as the width of the polycarbonate sheet. Then, use the telescopic cylinder 500 to drive the pressing parts to extrude the polycarbonate sheet. After a 3-second pause, the telescopic cylinder 500 drives the pressing parts to reset, thus completing the bonding of the polycarbonate sheet.
[0025] Example 2
[0026] In this embodiment, only the extrusion section 800 differs from that in Embodiment 1; the remaining structures are identical to those in Embodiment 1. In this embodiment, the extrusion section 800 includes an extrusion tube 806. A connection hole is formed on the side wall of the extrusion tube 806 near the adjustment hole 700. The extrusion tube 806 is inserted into the connection hole through the adjustment hole 700 by a bolt 807, thus fixing the extrusion tube 806 below the extrusion plate 600. When it is necessary to adjust the extrusion tube 806, only the bolt 807 needs to be adjusted to move the extrusion tubes 806 closer or further apart, so that the distance between the extrusion tubes 806 is adapted to the size of the polycarbonate sheet. The extrusion tube 806 is close to the mounting elastic layer of the mounting base 100, which provides elastic protection for the polycarbonate sheet.
[0027] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
