DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Combine the following Figures 1 to 7 The invention describes a glue recovery device for a glue coating and developing machine.

[0034] In one embodiment, a glue recovery device for a glue coating and developing machine includes a fixed seat 100, a lifting seat 300 and a sieve plate 200; the top of the fixed seat 100 is arranged in an open structure, and the interior of the fixed seat 100 has a storage cavity 131 arranged in a ring structure, and the bottom end of the storage cavity 131 is provided with a plurality of mounting openings 141; the lifting seat 300 is located directly above the fixed seat 100, and the bottom surface of the lifting seat 300 is used to abut against the storage cavity 131, so that the glue in the storage cavity 131 is squeezed through the plurality of mounting openings 141; the sieve plate 200 is installed at the outer bottom end of the fixed seat 100, and the screening parts of the sieve plate 200 are respectively matched with the plurality of mounting openings 141, and are used to filter the glue.

[0035] Specifically, the fixed seat 100 and the lifting seat 300 are both located in the same vertical direction, and the lifting seat 300 can be fitted against the surface of the fixed seat 100. Before recovering the glue, the sieve plate 200 is installed on the outer bottom end of the fixed seat 100, and then the glue collected in the developer is put into the storage cavity 131 of the fixed seat 100. At this time, the lifting seat 300 is located above the fixed seat 100. By controlling the lifting and lowering of the lifting seat 300, the space of the storage cavity 131 will be continuously compressed, and finally the glue will pass through the sieve plate 200 and enter the predetermined glue recovery position.

[0036] In the above-mentioned glue recovery device for the glue coating developer, the fixed seat 100 and the lifting seat 300 are both located in the same vertical direction, and the lifting seat 300 can be fitted against the surface of the fixed seat 100. Before recovering the glue, the sieve plate 200 is installed at the outer bottom end of the fixed seat 100, and then the glue collected in the developer is put into the storage cavity 131 of the fixed seat 100. At this time, the lifting seat 300 is located above the fixed seat 100. By controlling the lifting and lowering of the lifting seat 300, the space of the storage cavity 131 will be continuously compressed, and finally the glue will pass through the sieve plate 200 and enter the predetermined glue recovery position. At the same time, due to the external structure setting of the sieve plate 200, it is more convenient to repair and replace the sieve plate 200 in the subsequent process, and due to the annular structure setting of the storage cavity 131, there will be no cross-flow problem when the glue is filtered, and the entire filtering process is relatively more stable.

[0037] In one embodiment, the fixed seat 100 and the lifting seat 300 are both installed on the axial guide rod 500 in the vertical direction, the middle of the sieve plate 200 is located directly below the storage cavity 131, and the sieve plate 200 is fixed to the outer bottom end of the fixed seat 100 by installing bolts 400.

[0038] Specifically, the end of the axial guide rod 500 can be connected to the driving device, and a matching threaded transmission structure is set on the axial guide rod 500 and the lifting seat 300. In addition, the axial guide rod 500 can be used only for guidance, and the lifting and lowering of the lifting seat 300 is driven by a linear driving device. When installing the sieve plate 200, the sieve plate 200 is clamped at the center position of the outer bottom end of the fixing seat 100, and then the mounting bolt 400 is inserted into the sieve plate 200 and tightened, so that the sieve plate 200 can be installed.

[0039] In one embodiment, the fixed seat 100 includes a first fixed disk 110, a first annular bent plate 130, a first annular plate 140 and a first limiting cover 150; a first mounting hole 111 is opened at the corner of the first fixed disk 110 for installing the axial guide rod 500, one end of the first annular bent plate 130 passes through the first fixed disk 110, and the other end is located below the first fixed disk 110 and is bent toward the longitudinal center line of the first fixed disk 110, the outer circle of the first annular plate 140 is connected to the end of the first annular bent plate 130 away from the first fixed disk 110, and the inner circle of the first annular plate 140 is connected to the first limiting cover 150, and the first limiting cover 150 is arranged in an arched structure.

[0040] The lifting seat 300 includes a second fixed plate 310, a second annular bent plate 330, a third annular plate 340 and an arched limit ring 350; a third mounting hole 311 is opened at the corner of the second fixed plate 310 for mounting the axial guide rod 500, one end of the second annular bent plate 330 passes through the second fixed plate 310, and the other end is located below the second fixed plate 310 and is bent toward the longitudinal center line of the second fixed plate 310, a material guide tube 360 ​​is installed on the second annular bent plate 330, the outer ring of the third annular plate 340 is connected to one end of the second annular bent plate 330 away from the second fixed plate 310, and the inner ring of the third annular plate 340 is connected to the arched limit ring 350.

[0041] Specifically, the first annular bent plate 130 constitutes the above-mentioned storage cavity 131. When the second annular bent plate 330 moves toward the first annular bent plate 130, the openings therebetween will gradually come closer, and the internal space of the storage cavity 131 will shrink. Due to the setting of the annular bent plate, the glue in the storage cavity 131 will be squeezed and pushed to the bottom of the storage cavity 131, gathered above the first annular plate 140, and squeezed through the sieve plate 240 installed in the installation port 141 as the first annular plate 140 and the third annular plate 340 gradually fit together.

[0042] In one embodiment, a first extension ring 120 is connected between the first fixing plate 110 and the first annular bent plate 130 , and a second extension ring 320 is connected between the second fixing plate 310 and the second annular bent plate 330 .

[0043] Specifically, by providing an extension ring between the fixed disk and the annular bent plate, the lengths of the vertical surfaces of the fixed seat 100 and the lifting seat 300 are increased, so that during the nesting process of the fixed seat 100 and the lifting seat 300, the opening portion of the storage cavity 131 can be closed first, thereby preventing the glue from flowing out of the opening of the storage cavity 131 after being squeezed.

[0044] In one embodiment, the curvature of the surface of the arched limiting ring 350 is greater than the curvature of the surface of the first limiting cover 150 , the arched limiting ring 350 is elastic, and the elasticity of the arched limiting ring 350 gradually decreases from top to bottom.

[0045] Specifically, the arched limiting ring 350 can be made of plastic or rubber. In order to achieve the requirement that the elasticity of the arched limiting ring 350 gradually decreases from top to bottom, the thickness of each height of the arched limiting ring 350 can be changed, so as to limit the elasticity through thickness. Since the curvature of the surface of the arched limiting ring 350 is larger than that of the surface of the first limiting cover 150, when the lifting seat 300 moves into the fixed seat 100, the top of the arched limiting ring 350 will first come into contact with the top of the first limiting cover 150, and firmly abut against the first limiting cover 150 when the lifting seat 300 continues to rise and fall, thereby preventing the glue from flowing out from the middle of the storage cavity 131 during the squeezing process.

[0046] In one embodiment, the sieve plate 200 includes a second annular plate 210, a plurality of folding plates 220, a second limiting cover 230 and a plurality of sieve plates 240; the plurality of sieve plates 240 are arranged in an annular array on the second annular plate 210, the second limiting cover 230 is located at the center of the second annular plate 210, the second limiting cover 230 is connected to the inner circle of the second annular plate 210 through a plurality of folding plates 220 arranged in an annular array, and the sieve plate 240 is used to be clamped in the mounting port 141.

[0047] Specifically, an installation area 142 arranged in a ring structure is formed between the bottom surface of the first annular plate 140, the bottom end of the first annular bent plate 130 and the bottom end of the first limiting cover 150. The second annular plate 210 is clamped in the installation area 142. A plurality of through openings 143 are opened in the inner circle of the installation area 142. One end of the folding plate 220 is clamped in the through opening 143.

[0048] In one embodiment, the top of the first limiting cover 150 is set as the first plane end 151, and the top of the second limiting cover 230 is set as the second plane end 231. The interior of the first limiting cover 150 is an installation cavity 152, and a threaded installation tube 160 is arranged in the installation cavity 152. The top of the second limiting cover 230 is also opened with a second installation hole 232, and the installation bolt 400 passes through the second installation hole 232 and is installed in the threaded installation tube 160.

[0049] Specifically, the bottom end of the sieve plate 240 is a conical portion 241, which is arranged in a conical structure. The top end of the sieve plate 240 is a plate-shaped portion 242, which is arranged in a planar structure. By arranging the upper and lower parts of the sieve plate 240 with a special structure, the sieve plate 240 will not be affected in disassembly and assembly even if a certain strain is produced in a long-term high-pressure environment.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
