[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0031] This embodiment provides a roll-type silicon wafer transmission device, which can be used in a screen printer and is specifically used to transmit silicon wafers. The roll-type silicon wafer transmission device is arranged on a turntable so that when the turntable rotates to each station, it can receive silicon wafers transmitted from the upstream of the turntable, and after the turntable rotates, it is transferred to the bottom of the printing device, so as to facilitate the printing device to print grid lines on the silicon wafer. After the printing is completed, the turntable rotates again, and the roll-type silicon wafer transmission device carrying the silicon wafer that has just been printed is moved to the unloading station of the turntable, so as to facilitate the transmission of the printed silicon wafer to the downstream.

[0032] See also Figure 1 When the roll-type silicon wafer transmission device receives and outputs silicon wafers, the motor configured in the roll-type silicon wafer transmission device can drive the roll roller 2 to rotate forward or reversely, so that the roll paper drives the silicon wafer to move. After a unit of time of use, the roll paper must be rolled up by the roll paper roller 2, so that the clean roll paper replaces the part of the roll paper with dirty foreign objects on the working surface of the roll-type silicon wafer transmission device to avoid damaging the silicon wafer. After the roll paper is completely rolled up, the machine needs to be stopped to disassemble the roll paper roller 2 and replace the roll paper.

[0033] In order to facilitate the quick disassembly and assembly of the paper roll 2, the time spent on replacing paper materials is saved and the work efficiency is improved. This embodiment also provides a paper roll locking structure that can be configured in a paper roll type silicon wafer transmission device. For details, please refer to Figure 1 and Figure 2 The paper roll locking structure shown in the figure comprises a frame 1, a paper roll 2 arranged in the frame 1, and a first connecting portion 3 and a second connecting portion 4 coaxially and rotatably arranged on two side walls of the frame 1. In this embodiment, the first connecting portion 3 and the second connecting portion 4 are rotatably connected to the frame 1 through a bearing 5.

[0034] The first connecting portion 3 is located in a first embedding groove 31 set on the end surface of the frame 1, and the second connecting portion 4 is located in a second embedding groove 41 set on the end surface of the frame 1, and the second embedding groove 41 extends to the side wall of the second connecting portion 4, so that after one end of the paper roller 2 is embedded in the first embedding groove 31, the other end of the paper roller 2 can slide into the second embedding groove 41 from the side of the second connecting portion 4; the second connecting portion 4 has a slot 42 located in the second embedding groove 41, and a core shaft 7 can pass through the first connecting portion 3 and the paper roller 2 in sequence and then be plugged into the slot 42, so as to lock the paper roller 2 between the first connecting portion 3 and the second connecting portion 4; the paper roller locking structure also includes a locking component 6, and the locking component 6 can apply a force to the core shaft 7 to keep the core shaft 7 plugged into the second connecting portion 4.

[0035] With the above structure, the paper roller locking structure can lock the paper roller 2 between the first connecting part 3 and the second connecting part 4 by inserting or pulling out the core shaft 7, or enable the paper roller 2 to be moved out from between the first connecting part 3 and the second connecting part 4, so as to quickly replace the paper on the paper roller 2.

[0036] For details, please refer to Figure 2 and Figure 3 The first connecting portion 3 has a hollow cavity for passing the core shaft 7, and the core shaft 7 has a first shaft segment 71 and a second shaft segment 72 that are connected and both located in the hollow cavity. The first shaft segment is located on the side of the second shaft segment 72 that is away from the second connecting portion 4, and the diameter of the first shaft segment 71 is smaller than the diameter of the second shaft segment 72. The first shaft segment 71 is provided with a first hole 10 extending along the axial direction of the core shaft 7.

[0037] See also Figure 2 , Figure 3 and Figure 4 In this embodiment, the locking assembly 6 comprises an elastic element 61, a handle 62 and a pin 63, wherein the elastic element 61 is sleeved on the second shaft section 72 and abuts against the end surface of the first shaft section 71. The handle 62 is detachably connected to the first connecting portion 3, and comprises a connected handle body 621 and a hollow shaft body 622. The hollow shaft body 622 is radially provided with a second hole 20 that can communicate with the first hole 10 after the handle 62 compresses the elastic element 61. The hollow shaft body 622 can be sleeved on the second shaft section 72 from one end of the second shaft section 72 away from the first shaft section 71 to abut against the elastic element 61. The pin 63 can be inserted into the first hole 10 and the second hole 20 to fix the handle 62 to the core shaft 7. The elastic element 61 can be a spring.

[0038] Please refer to Figure 2 In order to prevent the paper roller 2 from axially moving when the paper roller 2 is locked between the first connecting portion 3 and the second connecting portion 4, the core shaft 7 also includes a third shaft segment 73 connected to the second shaft segment 72, and the third shaft segment 73 is used to carry the paper roller 2. The diameter of the third shaft segment 73 is smaller than that of the second shaft segment 72, and the end surface of the second shaft segment 72 connected to the third shaft segment 73 has a conical slope surface that can resist the paper roller 2.

[0039] Generally, centrifugal force is generated when the turntable rotates at high speed to switch positions, and the motor needs to frequently rotate forward and reverse when driving the paper roller 2 and the core shaft 7 to rotate, which also generates a certain centrifugal force. If the locking structure of the detachable structure of the first connecting part 3 and the rotating handle 62 is not stable enough, the rotating handle 62 may be easily thrown off when the turntable rotates and the paper roller 2 rotates, causing personal danger.

[0040] In view of the above, please refer to Figure 3 and Figure 4 The end of the first connection part 3 away from the second connection part 4 is provided with a "J"-shaped groove 30 extending axially along the first connection part 3. The "J"-shaped groove 30 includes a straight section 301 connected to the end wall of the first connection part 3, and a hook section 302 connected to the straight section 301. The straight section 301 allows the rotating handle 62 fixed with the pin shaft 63 to be inserted into the hollow cavity to press against the elastic element 61, and can make the rotating handle 62 fixed with the pin shaft 63 clamped at the end of the hook section 302 under the reverse stretching elastic force of the elastic element 61. The above structure can not only prevent the rotating handle 62 from falling off, but also make the rotating handle 62 and the core shaft 7 fixed to the rotating handle 62 easy to be removed, so as to achieve the purpose of quickly disassembling and assembling the paper roll 2.

[0041] In order to facilitate pushing and moving the handle 62 in the "J"-shaped groove 30, in this embodiment, the first hole 10 is a waist-shaped hole, and the waist-shaped hole extends along the axial direction of the core shaft 7 so that the handle 62 can slide relative to the core shaft 7. The length of the waist-shaped hole is not less than the axial length of the hook-shaped section 302. Therefore, when the handle 62 is manually pushed and moved toward the second connecting part 4 to unlock the handle 62, the core shaft 7 may not move with the handle 62. Conversely, when the core shaft 7 is inserted into the second connecting part 4, the handle 62 can be clamped or disengaged from the hook-shaped section 302 of the "J"-shaped groove 30.

[0042] This embodiment also discloses: a roll-type silicon wafer transmission device, which includes the roll-type silicon wafer transmission device and the roll-type silicon wafer transmission device. The roll-type silicon wafer transmission device includes the roll-type silicon wafer transmission device and the roll-type silicon wafer transmission device.

[0043] Specific embodiments are used in the present invention to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the technical solution and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
