[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figure 1 and Figure 8 As shown, the present invention is a resin product sticker device, comprising two symmetrically arranged support frames 1, a push plate 10 is fixedly mounted on the upper end surface of the support frame 1, a connecting plate 11 is fixedly mounted on the top of the push plate 10, an external frame 12 is commonly mounted between the connecting plates 11 on both sides, a liquid storage cylinder 14 and a liquid storage cylinder 2 15 are respectively mounted on both sides of the external frame 12, a piston rod 141 is slidably mounted on the middle part of the liquid storage cylinder 14, a contact frame 142 is fixedly mounted on one end of the piston rod 141, the piston rod 141 and the inner cavity of the liquid storage cylinder 14 are enclosed to form a cavity for storing hydraulic oil, a sticker mechanism 13 is detachably mounted on the middle part of the external frame 12, a cleaning mechanism is provided on both sides of the external frame 12, a plurality of equally spaced conveying frames 2 are rotatably mounted on the inner sides of the support frames 1 on both sides through a conveying mechanism, a flip frame 23 is provided in the middle part of the conveying frame 2, the flip frame 23 is connected to the conveying frame 2 through a flip assembly, and an opening and closing assembly is also provided on the flip frame 23; The cleaning mechanism includes a vertical groove opened on the external frame 12, in which a lifting member 16 is slidably installed. A spring is installed between the upper end surface of the lifting member 16 and the vertical groove. A shaft rod 161 is installed on the lifting member 16 for horizontal rotation. A gear 162 located in the middle of the lifting member 16 is fixedly installed in the middle of the shaft rod 161. The side of the gear 162 away from the external frame 12 is engaged with a tooth plate 143 fixed to the piston rod 141.

[0018] Rotating frames 163 are fixedly mounted on both ends of the shaft 161 , and a cleaning roller 164 for cleaning the resin plate before pasting is installed between the rotating frames 163 on both sides.

[0019] The conveying mechanism is opened to convey multiple conveying racks 2 to the bottom of the pasting mechanism 13 in sequence. At the same time, the push plate 10 is opened and retracted, and the external rack 12 is driven to descend through the connecting plate 11, and finally the resin plate on the conveying rack 2 is pasted on one side by the pasting mechanism 13. When the external rack 12 is performing the descending operation, the piston rod 141 first contacts the opening and closing assembly for supporting the resin plate. At this time, the piston rod 141 is subjected to the reaction force and moves upward in the liquid storage cylinder 14. When the piston rod 141 moves upward, the hydraulic oil in the cavity is compressed. After the hydraulic oil is compressed, it is transmitted to the liquid storage cylinder 2 15 for temporary storage. When the piston rod 141 moves upward, it simultaneously drives the cleaning mechanism to roll and clean the dust on the surface of the resin plate to be pasted. Compared with the existing pasting equipment, the present invention utilizes the ingenious cooperation between the cleaning mechanism and the pasting mechanism 13, so that the pasting mechanism 13 can first clean the resin plate before pasting the resin plate, thereby effectively avoiding the situation that the dust and impurities adhering to the outside of the resin plate during pasting affect the pasting effect. When the resin plate has completed single-sided pasting, the conveying mechanism drives the conveying frame 2 to continue moving. Since the conveying frame 2 is open up and down, and after the conveying mechanism rotates one circle, the flip frame 23 is again under the pasting mechanism 13. At this time, the flip component is opened to drive the flip frame 23 to flip in the conveying frame 2, and the opening and closing component cooperates with the flip component. At this time, the side of the resin plate with the pasted sticker is facing the ground, and the opening and closing component supports the resin plate with the pasted sticker, and the side of the resin plate that has not been pasted is facing the pasting mechanism 13. Repeating the downward movement of the pasting mechanism 13 can complete the pasting of both sides of the resin plate in sequence. Compared with the existing pasting device, the present invention can apply double-sided pasting to the resin plate, and there is no need to repeatedly flip and fix the resin plate when pasting.

[0020] It should be noted that the conveying mechanism is a pulley belt, and the pasting process of the pasting mechanism 13 is an existing technology to complete common pasting operations, so the pasting process will not be described in detail.

[0021] In this embodiment, a liquid inlet pipe 17 is provided on one side of the upper part of the liquid reservoir 14, which is connected to the inner cavity of the liquid reservoir 2 15. A liquid outlet pipe 18 is also provided on the side of the liquid reservoir 14 away from the liquid inlet pipe 17, which is connected to the liquid reservoir 2 15. A one-way valve is provided in the liquid outlet pipe 18 and the liquid inlet pipe 17. When the liquid reservoir 14 is compressed by the external force of the piston rod 141, the hydraulic oil in the inner cavity of the liquid reservoir 14 is discharged to the liquid reservoir 2 15 through the liquid outlet pipe 18. The space in the inner cavity of the liquid reservoir 14 on the side of the piston rod 141 away from the hydraulic oil generates a suction force. At this time, the dust on the surface of the resin plate can be adsorbed through the air pipe 191 and the air cylinder 19, thereby achieving a secondary cleaning effect. When the sticker mechanism 13 is finished cleaning the resin plate, the sticker After that, the push plate 10 opens and pushes up to move the sticker mechanism 13 away from the surface of the resin plate. At this time, the piston rod 141 loses its pressure. Since a spring is provided on the outside of the piston rod 141, the piston rod 141 quickly resets. When the piston rod 141 moves down and resets, it generates a suction force on the hydraulic oil in the cavity. At this time, the liquid inlet pipe 17 re-transfers the hydraulic oil in the liquid reservoir 2 15 to the liquid reservoir 1 14. At the same time, the space in the liquid reservoir 14 away from the side of the hydraulic oil is increasingly reduced as the piston rod 141 moves downward. At this time, the gas inside it can also blow the sticker on the resin surface through the air transfer pipe 191 and the air cylinder 19, which on the one hand accelerates the bonding speed between the hot melt adhesive surface of the sticker and the resin plate, and on the other hand promotes the fit between the sticker and the resin plate.

[0022] In this embodiment, when the piston rod 141 drives the contact frame 142 to move upward, it also synchronously drives the tooth plate 143 to move upward. When the tooth plate 143 moves upward, it drives the gear 162 to rotate. When the gear 162 rotates, it synchronously drives the rotating frame 163 to rotate through the shaft 161. When the rotating frame 163 rotates, it drives the cleaning roller 164 to rotate, thereby opening it after rolling on the surface of the resin plate, thereby making room for the sticker mechanism 13 to make stickers. The movement of the lifting member 16 in the vertical groove can also effectively avoid the restriction of the resin plate on the cleaning roller 164 when the rotating frame 163 drives the cleaning roller 164 to rotate, thereby ensuring that the cleaning roller 164 effectively rolls and sticks to the surface of the resin plate when following the rotating frame 163 to flip, so as to ensure that dust and impurities on its surface are removed.

[0023] Air cylinders 19 are fixedly installed at the four corners of the lower end surface of the external frame 12. A blowing port is provided in the middle of the lower end surface of the air cylinder 19. The multiple air cylinders 19 are connected to each other. An air transfer tube 191 is installed between the two air cylinders 19 on one side. The end of the air transfer tube 191 away from the two air cylinders 19 is connected to the lower part of the liquid storage cylinder 14.

[0024] Example 2: Based on Example 1, please refer to Figure 4 、 Figure 5 as well as Figure 6The four corners of the flip frame 23 are slidably installed with Y-shaped plates 24, and a through slot is provided above the Y-shaped plate 24, and a vertical rod 243 fixedly connected to the Y-shaped plate 24 is slidably installed in the through slot. Cylinders 241 are fixedly installed on both sides of the flip frame 23, and a movable frame 242 is fixedly installed on the telescopic end of the cylinder 241. The two sides of the movable frame 242 are respectively sleeved on the vertical rods 243 on both sides. Among them, when the cylinders 241 on both sides are opened and retracted, the movable frames 242 on both sides are respectively driven to move closer to each other. When the two movable frames 242 approach each other, the Y-shaped plate 24 is driven by the vertical rods 243 to move until the side edges of the diagonal corners of the resin plate are clamped and restricted. By restricting and fixing the four corners of the resin plate, on the one hand, it can prevent the resin plate from sliding when pasting stickers, and on the other hand, it can also prevent the resin plate from falling when the flip mechanism is opened to drive the flip frame 23 to flip.

[0025] In this example, see Figure 4-Figure 5 The cam 272 is fixed to the upper and lower parts of the frame 23 and the lower and lower parts of the frame 23 are fixed to the upper and lower parts of the frame 23.

[0026] The opening and closing assembly includes two groups of opening and closing plates 25 rotatably arranged on the left and right sides of the flip frame 23. The two opening and closing plates 25 of each group are always arranged at right angles. Side grooves 251 are provided at the front and back of the opening and closing plates 25. Moving blocks 252 are slidably installed in the side grooves 251. Center wheels 26 are installed on both sides of the flip frame 23 to rotate through a motor.

[0027] The center wheel 26 is meshed with racks 261 on the upper and lower sides that slide with the flip frame 23. The upper and lower racks 261 are respectively meshed with side wheels 262 that rotate with the flip frame 23. A flip plate 263 is coaxially installed on the front side of the side wheel 262. The flip plates 263 on both sides are arranged symmetrically, and the flip plates 263 are respectively connected to the upper and lower moving blocks 252.

[0028] It can be explained that when the motor is turned on, it drives the center wheel 26 to rotate. At this time, the rack 261 drives the side wheels 262 on both sides to rotate. When the side wheels 262 on both sides rotate, they synchronously drive the flip plate 263 to rotate. When the flip plate 263 rotates, it drives the states of the upper and lower opening and closing plates 25 to interactively change, so as to adapt to the flip frame 23 after flipping. The state conversion of the upper and lower opening and closing plates 25 is used to always support one side of the resin plate. Compared with the existing sticker device, the present invention can utilize the alternation of the states of the two opening and closing plates 25 to cope with the support of the resin plate after it is turned over, so as to avoid the situation where the resin plate falls off due to the single clamping of the outside of the resin plate when stickers are applied to the resin plate.
