Description

Technical Field

[0001] The invention relates to panel unloading equipment, and belongs to the field of automatic loading and unloading equipment. Background Art

[0002] In the current LCD panel production process, the loaded LCD panels need to be unloaded. The LCD panels are loaded on trays. The traditional unloading method is: manually pick up a tray containing LCD panels, remove the LCD panels placed on each tray, place them on the downstream conveyor line, and then stack the empty trays again.

[0003] The entire process of removing the LCD panels is done manually. This unloading method is inefficient and requires a high level of worker proficiency. When market demand is high, production volume must also increase accordingly, requiring a large number of workers and high labor intensity. However, when market demand is low, workers will be idle, resulting in high production costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a panel unloading device, which realizes the full automation of the unloading process of the liquid crystal panel and the tray, improves the production efficiency and reduces the production cost.

[0005] The panel unloading device described in the present invention includes a frame, a conveying mechanism is arranged in the frame, an induction conveying mechanism is arranged corresponding to the output end of the conveying mechanism, a clamping and lifting mechanism is arranged corresponding to the end of the induction conveying mechanism, a clamping and transferring mechanism and a panel taking mechanism are arranged corresponding to the tray on the clamping and lifting mechanism, and a lifting and transporting mechanism is arranged on one side of the clamping and lifting mechanism;

[0006] The clamping and lifting mechanism includes a lifting fork, a chuck clamp is symmetrically arranged at the lower part of the lifting fork, the chuck clamp is slidably connected to the lifting fork, and the lifting fork is slidably connected to the frame in the height direction; the clamping and transplanting mechanism includes a tray connecting frame, tray holes are arranged on the tray connecting frame corresponding to the tray, tray clamps are symmetrically arranged at the lower part of the tray connecting frame, the tray clamps are slidably connected to the tray connecting frame, the upper part of the tray connecting frame is slidably connected to the fixed plate, and the tray connecting frame is connected to the frame through the fixed plate.

[0007] The conveying mechanism transports the tray stack to the induction conveying mechanism, which transports the tray stack to the workstation of the clamping and lifting mechanism. The clamping and lifting mechanism lifts the tray stack, and the tray clamp on the clamping and transferring mechanism clamps the top tray. The panel taking mechanism takes out the LCD panel in the tray and puts it on the downstream conveyor line. The clamping and transferring mechanism transfers the empty tray to the lifting and transport mechanism, and then the clamping and lifting mechanism raises the tray stack by the height of one tray. At the same time, the lifting conveyor descends by the height of one tray until the panel taking mechanism takes out all the LCD panels in the tray stack. At this time, a stack of empty trays is stacked on the lifting and transport mechanism, and the lifting and transport mechanism recycles the empty trays for reuse.

[0008] The lifting fork is arranged in a U-shape, and the size of the U-shaped gap is larger than the outer size of the tray. The lifting fork is arranged in a U-shape to facilitate the tray to enter through the U-shaped gap.

[0009] The chuck clamp includes a positioning block, a support block extending inward from the bottom of the positioning block, and an L-shaped clamp. The positioning block clamps the tray, and the support block lifts the tray, thereby separating the tray from the guide conveyor mechanism.

[0010] The conveyor, the driving conveying mechanism, the clamping and lifting mechanism, the clamping and transplanting mechanism and the lifting and transporting mechanism are arranged in a U shape in the frame, with a compact structure and more reasonable space utilization.

[0011] The tray separation clamp includes a clamping block extending inward from the bottom of the clamping block. The tray separation clamp is arranged in a stepped manner. The tray separation block separates the top tray from the stacked trays. The clamping block clamps the separated tray, allowing the tray to enter the next process.

[0012] The guided conveyor mechanism includes a connecting plate with a conveying device mounted thereon, the connecting plate being horizontally slidably connected to the frame via a drive device. The tray stacks transported from the conveyor mechanism are driven by the drive device and transported by the conveyor device to a station within the clamping and lifting mechanism.

[0013] A baffle is provided on the frame corresponding to the end of the conveying device. The baffle serves to limit the tray stack being transported and prevent the tray stack from falling off the conveying device.

[0014] The lifting and transporting mechanism includes a lifting support plate with rollers disposed parallel to the lifting support plate. One side of the lifting support plate is slidably connected to a ball screw via a connecting seat. The lifting and transporting mechanism is used to carry empty trays and stack them into a tray stack on the lifting support plate, which can then be recycled for reuse.

[0015] The lifting support plate is provided with a guide rail corresponding to the ball screw, and the lifting support plate is slidably connected to the guide rail. The guide rail ensures the balance of the lifting support plate in the up and down movement and prevents the lifting support plate from tipping over.

[0016] The connecting seat is connected to the ball screw via a thread. The ball screw rotates to drive the connecting seat to move up and down, thereby driving the lifting support plate to move up and down.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The present invention realizes the full automation of the unloading process of liquid crystal panels and trays through the coordination of the actions of the conveyor, the driving conveying mechanism, the clamping and lifting mechanism, the clamping and transplanting mechanism, the lifting and transporting mechanism and the plate-taking mechanism, which can make the tray production line work non-stop, improve production efficiency, save labor costs and reduce enterprise expenses.

[0019] (2) The present invention not only smoothly removes the liquid crystal panel and places it in the downstream equipment, but also stacks the empty trays into stacks, making it convenient to transport them back for further use.

[0020] (3) The conveyor, the driving conveying mechanism, the clamping and lifting mechanism, the clamping and transplanting mechanism and the lifting and transporting mechanism are arranged in a U shape in the frame, with a compact structure and more reasonable space utilization.

[0036] Working process or working principle:

[0037] The tray stack coming from the upstream link enters the first station on the conveying mechanism, and the tray stack is transported to the second station on the induction conveying mechanism through the conveying mechanism. The induction conveying mechanism drives the tray stack to the third station on the clamping and lifting mechanism. The chuck clamp on the clamping and lifting mechanism is extended by the positioning cylinder to clamp and hold the tray stack, and then the electric actuator of the clamping and lifting mechanism drives the tray stack to rise, and moves the top tray into the clamping and transferring mechanism. At this time, the conveying device of the induction conveying mechanism returns to the second station, and the tray clamp of the clamping and transferring mechanism clamps the top tray of the tray stack. Because the upstream link causes the top tray to be an empty tray, only the empty tray needs to be removed, and the horizontal ball screw of the clamping and transferring mechanism drives the tray connecting frame to slide along the transverse guide rail to move the empty tray. The y tray is moved to the fourth station on the lifting and transport mechanism, and then the clamping and lifting mechanism raises the tray stack to the height of one tray. At the same time, the lifting and transport mechanism drops the height of one tray, and the suction cup on the robot takes the LCD panel from the second tray and places it on the downstream conveyor line. The empty tray is moved to the fourth station on the lifting and transport mechanism by the clamping and transferring mechanism. Each time the robot takes an LCD panel, the tray stack rises to the height of one tray, and the empty tray stack drops to the height of one tray, until the robot has taken all the LCD panels in the tray stack. At this time, a stack of empty trays is stacked on the lifting and transport mechanism, and the empty tray stacks are recycled and reused. The tray stacks from the upstream link enter the first station on the conveyor mechanism again, and the cycle repeats.

[0038] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up and down, does not constitute a limitation of the present invention and is only for the convenience of description.
