Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal glass production technology, specifically to a liquid crystal glass buffer mechanism. Background Technology
[0002] Production efficiency is crucial on LCD glass production lines. However, malfunctions inevitably occur in upstream or downstream equipment during operation, requiring shutdowns for maintenance. To ensure continuous production and improve efficiency, buffer devices are typically installed on the line. The main function of these devices is to temporarily store LCD glass when upstream or downstream equipment malfunctions, ensuring that equipment that is not shut down can continue operating.
[0003] Taking an LCD glass production line as an example, when downstream equipment of the buffer device is shut down for maintenance, the products flowing in from upstream can be placed into the buffer mechanism, thus ensuring the normal operation of the upstream equipment. Similarly, when upstream equipment of the buffer device is shut down for maintenance, the equipment handlers can remove the LCD glass from the buffer mechanism and allow it to flow into downstream equipment, ensuring the normal operation of the downstream equipment. This buffer device mitigates the impact of equipment downtime to a certain extent and reduces production losses.
[0004] However, existing caching devices have certain limitations when processing large-size LCD glass. For example... Figure 1 The buffer mechanisms currently available on the market primarily achieve this by extending the Z-axis travel of the conveyor and employing a multi-layer telescopic mechanism. This structure utilizes the suction handle of the conveyor to move glass within the buffer structure. However, this structure is complex, and the number of products buffered is limited, failing to meet customer requirements for production efficiency. Furthermore, the use of a multi-layer telescopic mechanism for the conveyor results in higher costs, hindering efforts to reduce production costs. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a liquid crystal glass buffer mechanism, which solves the problems of complex structure and limited number of products that can be buffered in existing liquid crystal glass buffer mechanisms.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a liquid crystal glass buffer mechanism, the buffer mechanism including a buffer rack for storing liquid crystal glass and a lifting and pulling mechanism disposed on one side of the pick-up and delivery opening of the buffer rack for picking up and delivering liquid crystal glass to the buffer rack;
[0007] The cache rack includes an aluminum profile frame and a multi-layer storage liquid crystal glass box disposed within the aluminum profile frame. Multiple roller bearings for carrying the box are evenly distributed on the inner side of the aluminum profile frame along the moving direction of the box picking and feeding.
[0008] The lifting and pulling mechanism includes a main frame and a gripper cylinder. A Y-axis reciprocating movement mechanism is provided inside the main frame, which drives the gripper cylinder to reciprocate within the main frame.

Multiple roller bearings supporting the boxes are evenly distributed inside the aluminum profile frame, effectively reducing the distance between the upper and lower boxes, ensuring the maximum stackable number of liquid crystal glass layers, guaranteeing structural stability, and increasing the capacity of the buffer equipment. The coordinated operation of the Y-axis reciprocating movement mechanism and the Z-axis reciprocating movement mechanism enables the buffer equipment to quickly and stably retrieve and feed the boxes. The buffer equipment can raise the boxes to the production line working height, facilitating the handling of liquid crystal glass by the main equipment's transporters, reducing handling difficulty, and improving production efficiency.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.
[0030] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0031] Reference Figures 2-7 A liquid crystal glass buffer mechanism of this embodiment is described.
[0032] The caching mechanism in this embodiment is as follows: Figure 2 As shown, it includes a cache rack for storing liquid crystal glass and a lifting and pulling mechanism 5 disposed on one side of the cache rack for picking up and feeding liquid crystal glass to the cache rack.
[0033] like Figure 2 and Figure 3 As shown, the buffer rack includes an aluminum profile frame 1 and multi-layer storage boxes 4 for storing liquid crystal glass, each box 4 containing one piece of liquid crystal glass. Multiple roller bearings 3, supporting the boxes 4, are evenly distributed along the moving direction of the boxes 4 inside the aluminum profile frame 1. The boxes 4 are supported by the roller bearings 3 and can be individually removed and inserted into the aluminum profile frame 1. The boxes 4 are made of 2040 aluminum profile. The roller bearings 3 are located in grooves on both sides of the aluminum profile frame 1, thus ensuring a safe clearance of 0.5cm-1cm between each layer of boxes 4 after accommodating the liquid crystal glass, guaranteeing the maximum number of stackable layers and saving equipment space.
[0034] In a specific implementation, the wall surface of the material box 4 has a groove, and the roller bearing 3 is embedded in the groove. The groove is located on the outer wall surface or bottom surface of the material box 4 (not shown in the figure). In a preferred embodiment, such as Figure 3 As shown, the groove is opened on the outer wall of the material box 4, which can reduce the gap between the upper and lower material boxes 4 and ensure the maximum number of stackable layers.
[0035] Furthermore, such as Figure 2 As shown, guide rollers 2 for the material box are provided on both sides of the aluminum profile frame 1 along the moving direction of the material box. The guide rollers 2 are arranged along the height direction of the aluminum profile frame 1, and their upper and lower ends are rotatably connected to the aluminum profile frame 1. There are multiple guide rollers 2, evenly distributed on both sides of the aluminum profile frame 1 along the moving direction of the material box. The guide rollers 2 limit the material box 4 during the process of taking it out and putting it into the aluminum profile frame 1, and prevent the direction from deviating when the material box 4 is pulled out.
[0036] In one implementation, such as Figure 4 As shown, the lifting and pulling mechanism 5 includes a main frame 58 and a gripper cylinder 54. A Y-axis reciprocating movement mechanism is provided inside the main frame 58. The Y-axis reciprocating movement mechanism drives the gripper cylinder 54 to reciprocate within the main frame 58. The gripper cylinder 54 is attached to the material box 4. When the Y-axis reciprocating movement mechanism reciprocates on the Y-axis, it drives the material box 4 to be taken out and fed in through the gripper cylinder 54. A Z-axis reciprocating movement mechanism is provided outside the main frame 58. The Z-axis reciprocating movement mechanism drives the main frame 58 to move up and down. The Z-axis reciprocating movement mechanism lifts the material box to the working height of the production line, which is convenient for the main equipment's transporter to move the glass.
[0037] In this embodiment, such as Figure 4 As shown, the Y-axis reciprocating mechanism includes a first motor 51, a driving shaft 52, and two driven shafts 59. The driving shaft 52 and the driven shafts 59 are located at both ends of the main frame 58, while the two driven shafts 59 are arranged opposite each other on both sides of the end of the main frame 58. The driving shaft 52 and the two driven shafts 59 are connected by two synchronous belts 53. Figure 4 and 6 As shown, the first motor 51 is fixed on the main frame 58, and the output end of the first motor 51 drives the active rotating shaft 52 to rotate through the transmission belt 512. The gripper cylinder 54 is fixed on the top surface of the transmission belt 512. When the transmission belt 512 rotates, the gripper cylinder 54 is moved from one end to the other end, realizing the Y-axis movement of the material box 4.
[0038] In operation, the Z-axis reciprocating mechanism adjusts the height of the main frame 58 so that the gripper cylinder 54 is positioned at the same horizontal level as the material box 4 being picked up. The first motor 51 drives the drive shaft 52 to rotate, which, in conjunction with the two driven shafts 59, drives the synchronous belt 53 to move. The synchronous belt 53 then moves the gripper cylinder 54 forward to clamp the material box 4. After clamping the material box 4, the first motor 51 rotates in the opposite direction, driving the synchronous belt 53 to pull the material box 4 out of the aluminum profile frame 1.
[0039] like Figure 5 As shown, a second guide rail 511 is fixed to the inner wall of the main frame 58 along the direction of the synchronous belt 53. A connecting slider 510 is fixed to one side of the gripper cylinder 54, and the connecting slider 510 is slidably connected to the second guide rail 511. The connecting slider 510 and the second guide rail 511 are used to support the gripper cylinder 54, so that the gripper cylinder 54 can carry the liquid crystal glass and move stably.
[0040] like Figure 7 As shown, a cable chain 513 is provided inside the main frame 58, and an air pipe 514 is passed through the inside of the cable chain 513. One end of the air pipe 514 is connected to a negative pressure device, and the other end of the air pipe 514 is connected to a gripper cylinder 54.
[0041] In this embodiment, such as Figure 4 As shown, the Z-axis reciprocating movement mechanism includes a lead screw 56 vertically mounted on the outside of the main frame 58. The lead screw 56 is connected to a second motor 55 that drives its rotation, and the lead screw nut on the lead screw 56 is fixed to the main frame 58. First guide rails 57 parallel to the lead screw 56 are provided on both sides of the lead screw 56, and the main frame 58 is slidably connected to the first guide rails 57 by a slider.
[0042] In actual operation, motor 55 drives lead screw 56 to move, lifting the main frame 58 containing material box 4 to the working height. The equipment's handling suction cup then places the LCD glass onto material box 4. After the glass is placed in, the second motor 55 moves in the opposite direction, driving material box 4 down to the initial position. Then, the first motor 51 operates, sending material box 4 into the aluminum profile frame 1, completing one buffering process.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
