Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to an adsorption-type loading and unloading robot. Background Technology

[0002] Automotive glass is a special type of glass designed specifically for vehicles to ensure driving safety, clear visibility, and comfort. Adsorption-type loading and unloading robots are automated devices that utilize vacuum adsorption technology to grasp and transport materials, offering advantages such as high adaptability, safety, and optimized efficiency. Adsorption-type loading and unloading robots are required to assist in the production and processing of automotive glass.

[0003] Chinese Patent CN118811492B discloses an adsorption-type glass loading and unloading device. It includes four parallel swing arms rotatably mounted in the space between the top horizontal support rods of two U-shaped vertical frames. A horizontal material carrier is rotatably connected to the beginning of each swing arm, and a horizontal support connecting rod is rotatably connected to the end of each pair of swing arms on each side. A tensioned rectangular chain is installed in the bottom part of the space between the two U-shaped vertical frames. Air valves are fixed on the longitudinal support rods of the U-shaped vertical frames, and the air valves are connected to a T-shaped air distribution pipe via flexible hoses. The chain drives the air valves to open and close simultaneously while driving the four swing arms to reciprocate. The automatic switching function of the negative pressure suction air source in this device relies entirely on a purely mechanical sliding valve core structure inside the air valve, pushed by a spring and driven by the chain. The implementation cost of the automation function is low, which helps to reduce the overall cost of the device.

[0004] However, the above technical solution has the following shortcomings: the device automatically switches the air valve to control the negative pressure suction air source, and then works with the suction pipe and suction cup to adsorb and release the glass. However, the glass is fragile and heavy, and the device has no protective structure. In the event of a sudden power failure, it may not be able to maintain the adsorption force, causing the glass to fall and be damaged. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an adsorption-type loading and unloading robot that can reinforce and prevent the adsorbed glass from falling off, thereby improving the stability and safety of the glass during the loading and unloading process and optimizing the practicality of the device.

[0006] The present invention provides an adsorption-type loading and unloading robot, comprising a mounting frame and an anti-detachment device. The mounting frame has multiple fixed rods, each with two positioning plates. The positioning plates have horizontally distributed first cylinders, which drive and connect to a movable plate. The anti-detachment device includes a second cylinder located outside the movable plate, a first connecting member on the movable plate, a second connecting member on the second cylinder, a fourth connecting member driven and connected to the second cylinder, a hinge on the movable plate, a rotating plate hinged to the movable plate via the hinge, a third connecting member on the rotating plate, and a claw on the rotating plate. The first and second connecting members are rotatably connected, as are the third and fourth connecting members.

[0007] Preferably, the mounting bracket is provided with a connecting flange.

[0008] Preferably, a first elastic pad is provided on the positioning plate.

[0009] Preferably, the mounting frame is provided with multiple symmetrically distributed fixed brackets, each fixed bracket is provided with a suction cup, and each suction cup is provided with a connector.

[0010] Preferably, the mounting bracket is equipped with four vacuum generators.

[0011] Preferably, the movable plate is provided with two horizontally distributed stabilizing bars, the mounting bracket is provided with multiple connecting rods, the connecting rods are provided with collars, and the stabilizing bars pass through the collars and are slidably connected.

[0012] Preferably, the movable plate is provided with two inclined mounting plates, the mounting plates are provided with clamps, and the clamps are provided with second elastic pads.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This utility model, through its anti-detachment device and clamping plate, can clamp and support the sides and bottom of the glass, thereby not only adsorbing the glass but also reinforcing it and preventing it from falling off. This avoids the risk of falling off during loading and unloading, ensures the safety of glass transfer, and has good practicality. Attached Figure Description

[0020] Example 1

[0021] like Figure 1 - Figure 4 As shown, the present embodiment proposes an adsorption-type loading and unloading robot, including a mounting frame 1 and an anti-detachment device; the mounting frame 1 is provided with multiple fixed rods 5, the fixed rods 5 are provided with two positioning plates 6, the positioning plates 6 are provided with horizontally distributed first cylinders 8, the first cylinders 8 are driven and connected to a moving plate 9, the mounting frame 1 is provided with multiple symmetrically distributed fixed brackets 2, and the fixed brackets 2 are provided with suction cups 4.

[0022] The anti-detachment device includes a second cylinder 14 disposed on the outside of the movable plate 9, a first connector 13 disposed on the movable plate 9, a second connector 15 disposed on the second cylinder 14, a fourth connector 17 drivenly connected to the second cylinder 14, a hinge 10 disposed on the movable plate 9, a rotating plate 11 hinged to the movable plate 9 via the hinge 10, a third connector 16 disposed on the rotating plate 11, and a pawl 12 disposed on the rotating plate 11; the first connector 13 and the second connector 15 are rotatably connected, and the third connector 16 and the fourth connector 17 are rotatably connected.

[0023] In this embodiment, when glass needs to be loaded or unloaded, the mounting bracket 1 is first driven downwards to approach the glass, so that the suction cup 4 adsorbs the glass and lifts it a short distance. Then, the first cylinder 8 is activated to drive the moving plates 9 on both sides to approach each other until the side of the glass is clamped. Then, the second cylinder 14 is activated to drive the fourth connector 17 to push the third connector 16, so that under the action of the hinge 10, the third connector 16 and the fourth connector 17 rotate relative to each other and rotate the rotating plate 11. At the same time, the fourth connector 17 drives the second connector 15 on the second cylinder 14 to rotate around the first connector 13 until the claw 12 on the rotating plate 11 abuts against the lower surface of the glass, thereby reinforcing the glass and preventing it from falling off. This avoids the risk of falling off during the loading and unloading process, ensures the safety of glass transfer, and has good practicality.

[0024] It should be noted that both the first cylinder 8 and the second cylinder 14 are double-acting cylinders equipped with two-position five-way dual-electric control solenoid valves. They have a memory function after power failure, and the cylinders remain in the state before power failure, so the force of the rods can be maintained.

[0025] Example 2

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, an adsorption-type loading and unloading robot is proposed. Compared with the first embodiment, in this embodiment, the mounting frame 1 is provided with a connecting flange 25, and the positioning plate 6 is provided with a first elastic pad 7.

[0027] The suction cup 4 is equipped with a connector 3, and the mounting bracket 1 is equipped with four vacuum generators 24.

[0028] In this embodiment, the connector 3 on the suction cup 4 is connected to the vacuum generator 24 via a branched air extraction pipe (not shown). When adsorption is required, the vacuum generator 24 removes the air inside the suction cup 4, creating a negative pressure that presses the glass against the surface of the suction cup 4 under atmospheric pressure. When detachment is required, the air extraction is stopped and air is injected into the suction cup 4 to balance the internal and external air pressures, thus eliminating the adsorption force. The connecting flange 25 is used to connect the intelligent robotic arm that drives the entire mounting frame 1. During adsorption, the robotic arm drives the mounting frame 1 to approach the glass from above, causing the suction cup 4 to press firmly against the glass until the upper surface of the glass adheres to the first elastic pad 7 on the positioning plate 6. Then, the vacuum generator 24 completes the adsorption, and the glass can then be loaded and unloaded.

[0029] Example 3

[0030] like Figure 3 and Figure 4 As shown, in this embodiment, an adsorption-type loading and unloading robot is proposed. Compared with the first embodiment, in this embodiment, the moving plate 9 is provided with two horizontally distributed stabilizing rods 21, the mounting frame 1 is provided with multiple connecting rods 22, the connecting rods 22 are provided with collars 23, the stabilizing rods 21 pass through the collars 23 and are slidably connected, the moving plate 9 is provided with two inclined mounting plates 18, the mounting plates 18 are provided with clamping plates 19, and the clamping plates 19 are provided with second elastic pads 20.

[0031] In this embodiment, when the first cylinder 8 drives the moving plate 9 to move, the moving plate 9 will drive the stabilizing rod 21 and the mounting plate 18 to move. The stabilizing rod 21 will slide through the inner hole of the collar 23 to guide the movement of the moving plate 9. The mounting plate 18 will drive the clamping plate 19 to move, so that the second elastic pad 20 on the clamping plate 19 abuts against the side of the glass, thereby reinforcing the side of the glass and further improving the stability during loading and unloading.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
