Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

In order to improve the aesthetic appearance of the mobile phone, the cover glass is usually subjected to sand blasting. Before sandblasting, the areas of the front and back of the cover plate glass which do not need sandblasting are covered by a protective film, and the protective film is torn off after sandblasting.

For this reason, this embodiment has proposed a two-sided dyestripping equipment, and two-sided dyestripping equipment has material loading station, first dyestripping station, upset station, second dyestripping station and receives the material station, and cover plate glass transports to each station along the transfer chain in proper order to accomplish the dyestripping and handle. When equipment on the station breaks down or the transfer frequency of cover plate glass is not matched with the processing frequency of certain station, the transfer line can block up, leads to cover plate glass to take place contact damage easily, has reduced the product yield.

In order to solve the above problem, as shown in fig. 1, this embodiment further provides a cache mechanism, where the cache mechanism includes a cache frame 1, a lifting module 2, and a transfer module 3. The buffer storage rack 1 is internally provided with a plurality of storage cavities which are arranged in sequence along the vertical direction. The lifting module 2 is in transmission connection with the buffer storage frame 1, so that the buffer storage frame 1 can lift in the vertical direction. When the cache frame 1 rises along the vertical direction, the transfer module 3 transfers a plurality of cover glass 10 to each storage cavity of the cache frame 1 in sequence; when the cache frame 1 descends along the vertical direction, the transfer module 3 sequentially transfers the cover glass 10 in each storage cavity out of the cache frame 1.

Specifically, in the storage process of the cover glass 10, after one cover glass 10 enters the corresponding buffer cavity, the buffer frame 1 is lifted for a certain distance, so that the cover glass 10 is separated from the transfer module 3, the next adjacent buffer cavity is communicated with the transfer module 3 again, and the transfer module 3 smoothly transfers other cover glass 10 to the buffer cavity. The above operations are repeated until a plurality of cover glasses 10 are sequentially stored in each storage cavity of the cache shelf 1. Similarly, in the process that the cover glass 10 enters the conveying line again, after the cache frame 1 descends for a certain distance, one of the cache cavities is communicated with the transfer module 3, so that the transfer module 3 bears the cover glass 10 in the cache cavity and transfers the cover glass 10 out of the cache cavity. Then after the cache frame 1 descends a certain height again, the transfer module 3 repeats the above operations until the cover glass 10 of each cache cavity is transferred to the conveying line one by one. It will be appreciated that the distance of each rise and fall of the cache frame 1 is equal.

When 2 drive buffer memory frame 1 of lifting module risees along vertical direction, transport module 3 and transport the storage intracavity of buffer memory frame 1 with the apron glass 10 on the transfer chain. When the lifting module 2 drives the cache frame 1 to descend along the vertical direction, the transfer module 3 sequentially transfers the cover glass 10 in each storage cavity out of the cache frame 1. The caching mechanism can prevent the cover glass 10 from being blocked on a conveying line, and smooth transfer of the cover glass 10 is realized. Meanwhile, the cover plate glass 10 is sequentially placed in the storage cavity, so that the cover plate glass 10 is independently stacked and placed, the space utilization rate of the cache frame 1 is improved, the cover plate glass 10 can be prevented from being in contact with each other to cause surface damage, and the product yield is improved.

As shown in fig. 2, the transferring module 3 includes a first bracket 31, a conveyor belt 32 and a transferring driving element 33, wherein one end of the first bracket 31 along the length direction thereof is located at the receiving station, and the other end thereof extends into the buffer storage rack 1. The conveyor belts 32 are disposed at both ends of the first support 31 in the longitudinal direction. The transfer driving part 33 can drive the conveyor belt 32 to operate so as to transfer the cover glass 10 from the receiving station to the storage cavity; or transferring the cover glass 10 in the storage cavity to a material receiving station.

The transfer driving member 33 of the embodiment is a rotating motor, and has the advantages of high control precision and convenience in installation. The transfer drive 33 drives the conveyor belt 32 to run on the first support 31 by means of a belt drive. It can be understood that the transferring module 3 further includes a driving wheel and a driven wheel, the driving wheel and the driven wheel are rotatably disposed on the first support 31, and the conveying belt 32 is wound around the driving wheel and the driven wheel, since the arrangement structure of the conveying belt 32 is a conventional technical means in the art, the detailed description thereof is omitted.

When the cover glass 10 needs to be cached, transplanting mechanisms such as manipulators in the double-sided film tearing equipment transfer the cover glass 10 on the conveying line to the material receiving station, namely, the cover glass is placed on the conveying belt 32 of the material receiving station. The transfer driving member 33 rotates forward, so that the conveyor belt 32 transfers the cover glass 10 from the material receiving station to the cache rack 1, and each cover glass 10 is inserted into a different cache cavity. When the conveying line returns to normal, the transfer driving piece 33 rotates reversely, so that the conveying belt 32 transfers the cover glass 10 to the material receiving station from the cache cavity, and transplanting mechanisms such as manipulators in the double-sided film tearing equipment transfer the cover glass 10 to the conveying line from the material receiving station.

Preferably, the transferring module 3 further includes guide plates 38, the guide plates 38 extend along the length direction of the first frame 31, the guide plates 38 are respectively installed on both sides of the first frame 31 along the width direction thereof, and a transferring passage of the cover glass 10 is formed between the two guide plates 38. The guide plate 38 can play a role in guiding and limiting the cover glass 10 in the transferring process, so that the cover glass 10 is prevented from deflecting or falling off at an angle on the conveyor belt 32, and the transferring precision of the cover glass 10 is improved.

Further, the transfer module 3 further comprises a first position sensor 34, and the first position sensor 34 is located below the material receiving station to detect whether the cover glass 10 reaches the material receiving station. When the first position sensor 34 detects that the cover glass 10 is on the material receiving station, the transfer driving member 33 is turned on to drive the conveyor belt 32 to operate, so that the cover glass 10 is transferred from the material receiving station into the cache frame 1.

When the cover glass 10 reaches the material receiving station, the first position sensor 34 is triggered and sends a signal to the control unit of the buffer mechanism or the double-sided film tearing equipment, so that the control unit controls the transfer driving piece 33 to be opened. Since the control unit is a buffer mechanism or a conventional functional module in the double-sided film tearing equipment, the working process of the control unit is not described in detail.

It should be noted that, when the cover glass 10 is buffered, the buffer rack 1 needs to undergo multiple height adjustments so that the conveyor belt 32 can be in sequential facing communication with the storage chambers. Therefore, the transferring module 3 further comprises a second position sensor 35, and the second position sensor 35 is located at the entrance position of the buffer storage rack 1 to detect whether the cover glass 10 reaches the entrance position.

Further, the transfer module 3 further includes a fourth position sensor 37 mounted on the first bracket 31, the first position sensor 34 and the fourth position sensor 37 are spaced apart from each other, and the spacing distance between the first position sensor and the fourth position sensor is greater than the length h of the cover glass 10. Specifically, the first position sensor 34 is spaced from the fourth position sensor 37 by approximately h +20mm. When the cover glass 10 moves from the material receiving station to the position of the fourth position sensor 37, the transplanting mechanisms such as the mechanical arms in the double-sided film tearing equipment stop transferring the cover glass 10 on the conveying line to the material receiving station, so that the material stacking phenomenon on the conveying belt 32 is avoided. After the cover glass 10 passes through the positions of the material receiving station and the fourth position sensor 37 in sequence, the transplanting mechanisms such as the mechanical arms in the double-sided film tearing equipment can continue to transfer the cover glass 10 on the conveying line to the material receiving station, so that the loading process of the transplanting mechanisms, the transfer process of the conveying belt 32 and the lifting process of the buffer storage frame 1 are matched, and reliable buffer storage of the cover glass 10 is realized.

It should be noted that the first position sensor 34, the second position sensor 35, and the fourth position sensor 37 are all in operation during the transfer of the cover glass 10 from the receiving station to the storage chamber.
