[0002] Commonly used conveying equipment includes belt conveyors, chain conveyors, roller conveyors, screw conveyors, bucket elevators, and stepper conveyors. In the production of LCD screens, stepper conveyors are required for processing needs, such as interval laser marking on the screen.

[0003] Patent CN210557411U discloses a circular material stepping conveyor device, comprising: a carrier for carrying circular materials, a support frame for moving circular materials, a first slide for driving the support frame to move along a first direction, and a second slide for driving the support frame to move along a second direction. The first slide is disposed on the second slide, and the support frame is provided with a plurality of positioning pins.

[0004] The circular material stepping conveyor does not have a buffering effect when placing materials downwards. When the conveyor line is long and materials need to be placed downwards frequently, it is easy to cause certain impact damage to the materials. Therefore, a conveying device that can have a buffering effect when placing materials downwards is needed. Utility Model Content

[0005] The purpose of this invention is to provide a conveying device for LCD screen production, which is used for step-transporting LCD screens to avoid collisions between screens during transportation. It also provides a buffer during the descent of the screens, thus improving the protection of the screens.

[0006] To achieve the above objectives, this utility model provides a conveying device for LCD screen production, including a base, side frames disposed on both sides of the base, and a stepping conveyor mechanism installed between the two side frames. An upper elongated plate and a lower elongated plate are installed on the outer side of the side frames. The upper elongated plate is disposed on the top of the side frame and a buffer plate is disposed on the upper elongated plate. A plurality of shock absorbers are arranged on the lower elongated plate. The shock absorber's shock-absorbing shaft passes through the lower elongated plate and the upper elongated plate and is connected to the buffer plate. A pressure block is fixedly sleeved outside the shock-absorbing shaft at a position below the upper elongated plate, and a spring is sleeved outside the shock-absorbing shaft between the pressure block and the lower elongated plate.

[0007] Preferably, the stepping transmission mechanism includes two sets of slide rails arranged and installed on the base. Each set of slide rails has a sliding plate slidably mounted on it. A vertical cylinder is mounted on the sliding plate. A U-shaped frame is mounted on the shaft end of the vertical cylinder. A support beam is mounted on the two end plates of the U-shaped frame. Multiple limiting grooves are arranged at equal intervals on the support beam.

[0008] Preferably, a transverse cylinder is mounted on the base between the two sets of slide rails via a cylinder seat; the cylinder shaft of the transverse cylinder is connected to a connector provided on one of the slide plates, and a slide seat that slides in cooperation with the slide rail is provided at the bottom of the slide plate.

[0009] Preferably, the bottom of the support beam is provided with a mounting plate, and the upright plate is provided with a slot corresponding to the mounting plate. After the mounting plate is inserted into the slot, it is locked with bolts.

[0010] Preferably, the side frame includes multiple uprights and a crossbeam plate fixed to the upper end of the uprights.

[0011] Preferably, a long strip limiting baffle is provided on the outer side of the upper long strip plate.

[0012] Preferably, the base is provided with multiple mounting holes.

[0013] According to the above technical solution, this utility model provides a conveying device for LCD screen production, including a base, side frames disposed on both sides of the base, and a stepping conveying mechanism installed between the two side frames. An upper elongated plate and a lower elongated plate are installed on the outer side of the side frames. The upper elongated plate is disposed on the top of the side frame and a buffer plate is disposed on the upper elongated plate. A plurality of shock absorbers are arranged on the lower elongated plate. The shock absorber's shock-absorbing shaft passes through the lower elongated plate and the upper elongated plate and is connected to the buffer plate. A pressure block is fixedly sleeved outside the shock-absorbing shaft at a position below the upper elongated plate, and a spring is sleeved outside the shock-absorbing shaft between the pressure block and the lower elongated plate.

[0014] The working principle and beneficial effects of the conveying equipment for LCD screen production are as follows: When conveying LCD screens, the screens from the previous production line are placed at the head of the stepping conveyor mechanism, and then conveyed to the next production line step by step. During the conveying process, both ends of the LCD screen need to be mounted on the buffer plate. This process is a top-down movement and placement process. At the moment of placement, the buffer plate is subjected to a downward force from the LCD screen. At this time, the force is transmitted to the shock absorber and buffered by the shock absorber. During the force transmission process, the pressure block compresses the spring, so that the spring plays an elastic support role, making the force transmission more moderate, thereby playing a certain protective role in the transmission of the screen.

[0015] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0024] See Figure 1-3The conveying equipment for LCD screen production shown includes a base 1, side frames disposed on both sides of the base 1, and a stepping conveyor mechanism installed between the two side frames. An upper long strip plate 3 and a lower long strip plate 7 are installed on the outer side of the side frames. The upper long strip plate 3 is disposed on the top of the side frame and a buffer plate 10 is disposed on the upper long strip plate 3. A plurality of shock absorbers 5 are arranged on the lower long strip plate 7. The shock absorber shaft 24 of the shock absorber 5 passes through the lower long strip plate 7 and the upper long strip plate 3 and is connected to the buffer plate 10. A pressure block 22 is fixedly sleeved on the outside of the shock absorber shaft 24 below the upper long strip plate 3. A spring 6 is sleeved on the outside of the shock absorber shaft 24 between the pressure block 22 and the lower long strip plate 7.

[0025] Through the implementation of the above technical solution, when conveying the LCD screen, the screen from the previous production line is placed at the head position of the stepping conveyor mechanism, and then conveyed to the next production line step by step. During the conveying process, both ends of the LCD screen need to be mounted on the buffer plate 10. This process is a top-down movement and placement process. At the moment of placement, the buffer plate 10 is subjected to a downward force from the LCD screen. At this time, this force is transmitted to the shock absorber 5 and buffered by the shock absorber 5. During the force transmission process, the pressure block 22 compresses the spring 6, so that the spring 6 plays an elastic support role, making the force transmission more moderate, thereby providing a certain degree of protection for the transmission of the screen. The shock absorber 5 can be an adjustable damping hydraulic shock absorber, selected according to the weight of the material.

[0026] In this embodiment, to further provide a stepping transmission mechanism, the stepping transmission mechanism includes two sets of slide rails 16 arranged and installed on the base 1.

After being lifted by the vertical cylinder 15 and moved backward by the sliding plate 23, the LCD screen is moved above the buffer plate 10. Then, the vertical cylinder 15 retracts, and the two ends of the LCD screen are mounted on the buffer plate 10. The sliding plate 23 moves forward to return to its initial position, and then the next LCD screen is conveyed. At the same time, the previous LCD screen is continued to be conveyed backward.

[0027] In this embodiment, a transverse cylinder 20 is mounted on the base 1 between the two sets of slide rails 16 via a cylinder seat 19.
