Description

TECHNICAL FIELD

[0001] The present application relates to the field of LCD processing and production, and particularly relates to a buffer machine for LCD glass processing. BACKGROUND

[0002] In an LCD production line, sometimes the next process will fail or stop unexpectedly, at this time, if the whole production line is not closed, the semi-finished product will be accumulated in front of the process. Taking the pre-baking process and the glue coating process in the production of LCD as an example, the liquid crystal glass needs to be pre-baked in the pre-baking furnace first, and then coated with glue in the glue coating machine. However, in the actual production process, the glue coating machine of the next process often needs to be stopped, while the pre-baking furnace is in normal operation. The current production line directly connects the pre-baking furnace and the glue coating machine, and there is no buffer device between them. Therefore, when the glue coating machine fails or stops, the pre-baking furnace also needs to be stopped, otherwise the liquid crystal glass in the pre-baking furnace will be baked and damaged, thereby affecting the subsequent processing efficiency.

[0003] The existing LCD glass buffer machine has a complex transmission structure design due to the control limitation of transmission, and uses ordinary transmission belts to connect between transmission wheels, which has a large friction surface and is easy to cause friction to affect the quality of the LCD glass. SUMMARY

[0004] The purpose of the present application is to provide a buffer machine for LCD glass processing which is different from the prior art, and has the advantages of simple transmission structure and small transmission contact friction surface.

[0005] The technical scheme adopted by the present application to solve the technical problem is: a buffer machine for LCD glass processing, comprising a rack, a lifting support which can be lifted is arranged on the rack, a support plate for placing an LCD glass buffer column is arranged on the top of the lifting support, a group of lifting avoidance openings are formed in the support plate, and each lifting avoidance opening is independent of each other; a transmission support is arranged in each lifting avoidance opening of the rack, and a transmission assembly for transmitting the LCD glass is arranged on the top of each transmission support; the lifting avoidance openings are arranged in two rows, and the two rows of lifting avoidance openings are arranged in one-to-one correspondence and alignment; each transmission assembly comprises a transmission shaft which is rotatably arranged on the upper part of the transmission support, a transmission wheel is arranged at the end of the transmission shaft on one side of the outer side wall of the transmission support, and a power wheel is arranged at the end of the transmission shaft on one side of the inner side wall of the transmission support; the top of the transmission wheel is arranged higher than the top of the transmission support, and the top end of the power wheel is arranged lower than the top of the transmission support; a stepping motor is arranged below the transmission wheel on the outer side wall of the transmission support, a driving wheel is arranged below the power wheel on the inner side wall of the transmission support, the shaft of the stepping motor penetrates the transmission support and the driving wheel, a fluorine rubber ring is arranged between the driving wheel and the power wheel for connecting the two, and the transmission outer ring of the transmission wheel is sleeved with the fluorine rubber ring.

[0006] Furthermore, each transmission component includes two transmission shafts, with a transmission wheel and a power wheel at both ends of each transmission shaft. The transmission wheels on the two transmission shafts are located on the same side and are horizontally aligned. The power wheels on the two transmission shafts are located on the same side and are horizontally aligned. There is one drive wheel located below the middle of the two power wheels. Each of the two power wheels is equipped with a fluororubber ring for connecting to the drive wheel.

[0007] Furthermore, each drive wheel and drive wheel has two inner and outer ring rubber ring mounting grooves formed on its outer side wall; the outer ring rubber ring mounting groove of one drive wheel and the outer ring rubber ring mounting groove of the drive wheel are connected by a fluororubber ring, and the inner ring rubber ring mounting groove of the other drive wheel and the inner ring rubber ring mounting groove of the drive wheel are connected by a fluororubber ring.

[0008] Furthermore, each of the four corners of the lifting bracket is equipped with a right-angle positioning block for positioning the LCD glass buffer bar.

[0009] Furthermore, the lifting clearance is provided in two rows, with each row of lifting clearances aligned and corresponding to the other.

[0010] Furthermore, at least two lifting clearance openings are provided, and they are in the same row; the height and horizontal position of the transmission bracket are adjustable.

[0011] Furthermore, it also includes a PLC control system, with each stepper motor connected to the PLC control system, which is used to control the synchronous rotation of each stepper motor.

[0012] The beneficial effects of this invention are as follows: By providing a set of lifting clearance openings on the support plate, compared to the prior art where all transmission components are located in one lifting clearance opening, the strength of the support plate structure can be improved, making the LCD glass buffer rails on it more stable and reliable when the lifting bracket is raised and lowered. Each lifting clearance opening is equipped with a transmission component, which includes a transmission wheel, a power wheel, a stepper motor, and a drive wheel, thereby improving the space utilization of the space where the support plate is located while ensuring the transmission function.

[0013] Each transmission component is equipped with a stepper motor, enabling independent control of each component and resulting in a more stable and reliable structure.

[0014] Meanwhile, fluororubber rings are used to connect the active and drive wheels, and fluororubber rings are also fitted around the outer ring of the transmission wheel. Compared with the common use of transmission belts for connection and transmission, this effectively reduces the contact area between the transmission wheel and the LCD glass during transmission, reducing dust generation due to friction. This provides the existing market with a new buffer machine option for LCD glass processing, offering advantages such as simple spacing structure, stable and reliable transmission, and a smaller contact friction surface during transmission.

[0015] 2. Each transmission assembly comprises two transmission shafts, two transmission wheels and two power wheels, which are driven by a stepping motor and a driving wheel, and more transmission structures are provided in a lifting avoiding gap by the setting of inner and outer circle rubber ring setting grooves, so as to improve the overall transmission stability and space utilization. Meanwhile, when the LCD glass is small, only two avoiding gaps are set, corresponding to two transmission assemblies, so that the stable transmission of the LCD glass can be realized.

[0016] 3. The right-angle positioning block can conveniently arrange the LCD glass buffer and position the LCD glass buffer.

[0017] The application will be described in detail below in combination with the drawings and embodiments. BRIEF DESCRIPTION OF DRAWINGS
