[0019] like Figures 1 to 7 As shown, in this embodiment, the utility model includes a pressure plate assembly 1 and a buffer assembly 2, the pressure plate assembly 1 includes a fixture module 11 and a flip-cover pressure plate 12, the rotating side of the flip-cover pressure plate 12 is hinged to the rotating side of the fixture module 11, the buffer assembly 2 is arranged on the upper end surface of the fixture module 11 and cooperates with the flip-cover pressure plate 12, the buffer assembly 2 includes a cylinder 21 and an elastic pin module 22, the elastic pin module 22 includes an elastic pin mounting seat 221 and an elastic pin 222, the movable end of the cylinder 21 is provided with a piston rod 23, and the cylinder 21 drives the piston rod 23 to cooperate with the elastic pin 222 on the elastic pin mounting seat 221. It can be seen that when the product 7 is not normally placed in the jig module 11 and the flip cover pressure plate 12 presses down the jig module 11, the upper end of the elastic pin 222 cooperates with the flip cover pressure plate 12 to prevent the flip cover pressure plate 12 from pressing the jig module 11. When the product 7 is normally placed in the jig module 11, the movable end of the elastic pin 222 can be pressed down normally, so that the flip cover pressure plate 12 can press the jig module 11 normally. The structure is simple and the performance is stable.
[0020] like Figures 1 to 7 As shown, in this embodiment, the cylinder 21 is arranged on the upper end surface of the support position of the elastic pin mounting seat 221, the buffer position of the elastic pin mounting seat 221 is provided with an elastic pin mounting through hole 3, the elastic pin 222 and the elastic pin mounting through hole 3 are limited and matched, and piston rod openings 4 are provided on both sides of the buffer position of the elastic pin mounting seat 221. The cylinder 21 drives the piston rod 23 through the piston rod opening 4 to match with the bottom of the movable end of the elastic pin 222. It can be seen that when the cylinder 21 drives the piston rod 23 through the piston rod opening 4, the movable end of the elastic pin 222 is blocked and cannot be pressed down normally, so that the flip cover pressure plate 12 cannot be pressed normally. When the cylinder 21 is restored, the movable end of the elastic pin 222 can be pressed down normally, and the flip cover pressure plate 12 can be pressed normally and tested.
[0021] like Figure 6 and Figure 7 As shown, in this embodiment, a flexible adhesive layer 5 is provided on the top of the movable end of the elastic pin 222, and the flexible adhesive layer 5 matches the lower end surface of the flip cover pressing plate 12. It can be seen that the flexible adhesive layer 5 can prevent the elastic pin 222 from scratching the flip cover pressing plate 12.
[0022] like Figures 1 to 4As shown, in this embodiment, the fixture module 11 includes a bottom plate 111 and a product fixing seat 112, and a plurality of optical fiber probes 6 are arranged on both sides of the product fixing seat 112, and the plurality of optical fiber probes 6 are inductively matched with the product 7 on the product fixing seat 112. It can be seen that the product positioning seat 112 is equipped with two optical fiber probes 6 for detecting whether the product 7 is inserted and whether it is inserted in place, which can synchronously transmit the placement status of the product to the control module, and synchronously control the extension and recovery of the movable end of the cylinder 21, so as to control whether the flip cover pressing plate 12 can normally press down the fixture module 11.
[0023] like Figure 1 , Figure 3 as well as Figure 4 As shown, in this embodiment, the armrest side of the flip cover pressing plate 12 is provided with a buckle 8, and the side of the bottom plate 111 corresponding to the buckle 8 is provided with a locking and fixing block 9, and the buckle 8 cooperates with the locking and fixing block 9. It can be seen that after the flip cover pressing plate 12 is pressed down, the buckle 8 fastens the locking and fixing block 9 to prevent the flip cover pressing plate 12 from bouncing open and causing damage to the product 7.
[0024] like Figure 1 As shown, in this embodiment, a handle 10 is provided on the armrest side of the flip cover pressing plate 12. It can be seen that the handle 10 can facilitate the operator to unlock the flip cover and load and unload materials.
[0025] like Figure 1 As shown, in this embodiment, a rotating block 113 is provided on the side of the bottom plate 111 corresponding to the rotating side of the flip cover pressing plate 12, and the rotating side of the flip cover pressing plate 12 is hingedly connected to the rotating block 113. It can be seen that the rotating side of the flip cover pressing plate 12 and the rotating block 113 are rotated in cooperation to achieve single-sided downward pressure.
[0026] The working principle of the utility model is as follows: before the equipment is started, the flip cover pressing plate 12 is opened, and the movable end of the cylinder 21 drives the piston rod 23 to pass through the piston rod opening 4, so that the movable end of the elastic pin 222 cannot be pressed down normally, and the product 7 is placed in the product fixing seat 112, and the flip cover pressing plate 12 is rotated and pressed down. When several of the optical fiber probes 6 detect that the product 7 is not placed in place, the cylinder 21 remains in an extended state, and the flip cover pressing plate 12 cannot be pressed down normally. The flip cover pressing plate 12 is opened to adjust the position of the product 7. When the product 7 is placed normally, several of the optical fiber probes 6 normally identify the product 7, and the movable end of the cylinder 21 returns to its initial position. The flip cover pressing plate 12 can press down the elastic pin 222 normally. After being pressed into place, the buckle 8 fastens the locking and fixing block 9 and performs detection. After the detection is completed, the buckle 8 is unlocked, the flip cover pressing plate 12 is opened, and the product 7 is replaced. The above steps are repeated to complete the automatic cylinder buffering downward pressure.
[0027] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
