[0050] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0051] The existing work platform cannot meet the operation of substrates of different sizes and has poor versatility. For the working conditions of producing substrates of various sizes, multiple work platforms need to be equipped, resulting in high cost of use. The embodiment of the utility model provides a platform with adjustable substrate operation area, which can choose to use the first placement surface, the first placement surface and the second placement surface and / or the third placement surface, which can meet the operation requirements of substrates of various sizes and effectively reduce the cost of use.

[0052] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0053] According to the embodiments of the present utility model, Figure 1 and Figure 2As shown, a substrate working platform is provided, which mainly includes: a main platform 1, a first auxiliary platform 2 and a second auxiliary platform 3. The main platform 1 includes a frame 101 and a plurality of first rollers 102 arranged at intervals on the frame 101, and the plurality of first rollers 102 form a first placement surface. One end of the first auxiliary platform 2 is rotatably arranged at the first edge of the frame 101, and is provided with a plurality of second rollers 201 arranged at intervals, and the plurality of second rollers 201 form a second placement surface. One end of the second auxiliary platform 3 is rotatably arranged at the second edge of the frame 101, and is provided with a plurality of third rollers 301 arranged at intervals, and the plurality of third rollers 301 form a third placement surface, and the first edge is adjacent to the second edge. The substrate working platform has a first state and a second state. In the first state, the first placement surface is coplanar with the second placement surface and the third placement surface, and in the second state, the second placement surface and / or the third placement surface rotates to form an angle with the first placement surface.

[0054] In the embodiment of the utility model, the substrate operation platform can be adjusted to the first state for a substrate with a larger size, and the substrate operation surface is formed by the first placement surface, the second placement surface and the third placement surface together, and the substrate operation platform can be adjusted to the second state for a substrate with a smaller size, and the substrate operation surface is formed by only the first placement surface, or the combination of the first placement surface and the second placement surface, or the combination of the first placement surface and the third placement surface, so it can be applied to the operation requirements of substrates of different sizes, effectively reducing the use cost. In addition, by forming multiple placement surfaces respectively through multiple rollers, it is also beneficial for the flow and transportation of substrates on the substrate operation platform, which is convenient for use.

[0055] Since the substrate is generally square, the main platform 1 is also designed to be square. The first auxiliary platform 2 and the second auxiliary platform 3 can also be square, and can be turned 90 degrees around the edge of the main platform 1 respectively, so that the first auxiliary platform 2 and the second auxiliary platform 3 are lowered to prevent them from obstructing the operator's work. Specifically, the first edge is located downstream of the substrate moving direction on the main platform 1, and the second edge is perpendicular to the first edge.

[0056] Of course, in some other embodiments, the first auxiliary platform 2 and the second auxiliary platform 3 may be flipped to other angles as needed.

[0057] In addition, in the second state, the operator can choose to put down only the first auxiliary platform 2 or the second auxiliary platform 3 as needed, or can put down both the first auxiliary platform 2 and the second auxiliary platform 3 to accommodate substrates of different lengths and widths.

[0058] In one embodiment, Figure 2 and Figure 4As shown, the frame 101 is also provided with a driving member, a transmission assembly and a plurality of first transmission shafts 103, the plurality of first transmission shafts 103 are rotatably mounted on the surface of the frame 101, the plurality of first rollers 102 are respectively sleeved on the plurality of first transmission shafts 103 at intervals, and the driving member is connected to the plurality of first transmission shafts 103 through the transmission assembly. By driving the transmission assembly through the driving member to drive the first transmission shafts 103 to rotate, automatic transportation of the substrate can be realized, further improving the convenience of substrate operation.

[0059] It should be noted that the embodiment of the utility model does not limit the driving member, and the driving member can select any existing structure, such as a motor. The motor can be fixed on the frame 101.

[0060] In addition, the embodiments of the present invention do not limit the transmission assembly.

[0061] In one embodiment, Figure 4 As shown, the transmission assembly mainly includes: a driving gear, a plurality of first driven gears 104 and a plurality of transmission chains. The driving gear is connected to the driving end of the driving member. The plurality of first driven gears 104 are sleeved on each first transmission shaft 103 in pairs. One of the transmission chains is sleeved on the driving gear and the first driven gear 104 of the first transmission shaft 103 located at the outer edge, and the remaining transmission chains are sleeved on the first driven gears 104 of the adjacent first transmission shafts 103 in sequence.

[0062] By driving the driving gear to rotate through the driving member, and then transmitting the rotation of the driving gear to the first driven gear 104 of each first transmission shaft 103 through multiple transmission chains, the synchronous rotation of multiple first transmission shafts 103 can be achieved with high rotation accuracy, which can prevent the substrate from getting stuck on the main platform 1 or causing damage to the substrate due to asynchronous movement of multiple first transmission shafts 103.

[0063] In one embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the first auxiliary platform 2 mainly includes: a first bracket 202, a first telescopic member 203 and a plurality of second transmission shafts 204. One end of the first bracket 202 is rotatably arranged on the first edge. One end of the first telescopic member 203 is arranged on the frame 101, and the other end is connected to the other end of the first bracket 202. The plurality of second transmission shafts 204 are rotatably installed on the surface of the first bracket 202 at intervals. The plurality of second rollers 201 are respectively sleeved on the plurality of second transmission shafts 204 at intervals, and each second transmission shaft 204 is respectively provided with a pair of second driven gears 205, one of the transmission chains is sleeved on the adjacent first driven gear 104 and the second driven gear 205, and the plurality of transmission chains are also sequentially sleeved on the second driven gears 205 of the adjacent second transmission shafts 204.

[0064] The first bracket 202 is driven to rotate around the first edge by the first telescopic member 203, so as to realize the splicing and separation of the first placement surface and the second placement surface. The synchronous rotation of the plurality of second transmission shafts 204 and the plurality of first transmission shafts 103 can also be ensured by the cooperation of the plurality of transmission chains and the second driven gear 205 of the second transmission shaft 204.

[0065] Since the first bracket 202 needs to rotate around the first edge, the distance between the adjacent first driven gear 104 and the second driven gear 205 will change during the rotation process. In order to prevent transmission failure, the transmission chain sleeved on the adjacent first driven gear 104 and the second driven gear 205 needs to be made of soft elastic material, such as plastic.

[0066] In one embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the second auxiliary platform 3 mainly includes: a second bracket 302, a second telescopic member 303 and a plurality of third transmission shafts 304. One end of the second bracket 302 is rotatably arranged on the second edge. One end of the second telescopic member 303 is arranged on the frame 101, and the other end is connected to the other end of the second bracket 302. A plurality of third transmission shafts 304 are rotatably installed on the surface of the second bracket 302 at intervals. A plurality of third rollers 301 are respectively and spaced apart and sleeved on the plurality of third transmission shafts 304. The axis of each third transmission shaft 304 is colinear with the axis of a first transmission shaft 103, and is provided with a first transmission part 3041, and the first transmission shaft 103 is provided with a second transmission part 1031 corresponding to the first transmission part 3041, and in the first state, the first transmission part 3041 is connected to the second transmission part 1031.

[0067] The second bracket 302 is driven to rotate around the second edge by the second telescopic member 303, so as to realize the splicing and separation of the first placement surface and the third placement surface. The first transmission part 3041 cooperates with the second transmission part 1031, so as to ensure the synchronous rotation of the plurality of third transmission shafts 304 and the plurality of first transmission shafts 103.

[0068] It should be noted that the embodiment of the utility model does not limit the first telescopic member 203 and the second telescopic member 303, as long as the first telescopic member 203 can drive the first bracket 202 to flip around the frame 101, and the second telescopic member 303 can drive the second bracket 302 to flip around the frame 101. Exemplarily, for ease of use, the first telescopic member 203 and the second telescopic member 303 both use cylinders with a self-locking function.

[0069] In addition, the structures of the first transmission part 3041 and the second transmission part 1031 are not limited.

[0070] Further, in one embodiment, if Figure 6 As shown, the end of the first transmission shaft 103 close to the third transmission shaft 304 is axially extended to form the second transmission part 1031, and the end of the third transmission shaft 304 close to the first transmission shaft 103 is radially extended to form the first transmission part 3041. When the first placement surface is coplanar with the third placement surface, the first transmission part 3041 is in contact with the second transmission part 1031, and the first transmission part 3041 drives the second transmission part 1031 to rotate, so as to realize the synchronous rotation of the third transmission shaft 304 and the first transmission shaft 103, which has a simple structure and is convenient for transporting substrates. When the first placement surface is at an angle to the third placement surface, the first transmission part 3041 is separated from the second transmission part 1031 and no longer transmits motion, so as to save energy consumption.

[0071] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the frame 101 is also provided with a lifting mechanism 4, and a plurality of support columns 401 are provided on the lifting mechanism 4. The plurality of support columns 401 are spaced and distributed at the gaps between the plurality of first rollers 102, and the plurality of support columns 401 form a fourth placement surface, and the lifting mechanism 4 is used to drive the fourth placement surface to move along the height direction of the frame 101. When the substrate is misplaced, the plurality of support columns 401 can be driven to rise by the lifting mechanism 4, and the height of the fourth placement surface can be made greater than the height of the first placement surface. At this time, the substrate is located on the fourth placement surface and is only supported and fixed by the plurality of support columns 401, so that the position of the substrate can be adjusted conveniently.

[0072] It should be noted that the present invention does not limit the lifting mechanism 4, and any existing structure can be selected as needed.

[0073] Furthermore, in one embodiment, a ball bearing is disposed on the top of each support column 401. The sliding friction between the substrate and the support column 401 can be transformed into rolling friction, which is beneficial for adjusting the position of the substrate and can also reduce the wear of the substrate.

[0074] In one embodiment, the substrate work platform further includes a plurality of support wheels 5, which are spaced apart at the bottom of the frame 101. By spaced apart at the bottom of the frame 101, the entire substrate work platform can be driven to move and the substrate work platform can be transported conveniently.

[0075] Specifically, four supporting wheels 5 can be optionally provided, which are respectively located at the four corners of the main platform 1 , with a simple structure and convenient use.

[0076] In one embodiment, the substrate working platform further includes a plurality of legs 6, which are spaced apart at the bottom of the frame 101. By spaced apart at the bottom of the frame 101, the substrate working platform can be effectively supported, and the stability of the substrate working platform can be improved.

[0077] Specifically, four legs 6 can be provided, respectively located at the four corners of the main platform 1, and the legs 6 can be retracted and self-locking. When the substrate work platform is in normal use, the legs 6 extend to contact the ground and lift the support wheels 5 to prevent the substrate work platform from moving. When the substrate work platform is transported, the legs 6 retract, the support wheels 5 contact the ground, and drive the substrate work platform to move.

[0078] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
