[0044] Referring to

[0045] Please refer toFigures 1 to 3 , the present application provides an auxiliary device 10 for a rotary printing machine, which is applied to a rotary printing machine 100. The auxiliary device 10 for a rotary printing machine includes a base 11 and a carrier table 12. Among them, the base 11 has an avoidance space 11a for avoiding the turntable 30 of the rotary printing machine 100, and there is a first operation port 11b above the avoidance space 11a. The carrier table 12 is movably arranged on the base 11, and the carrier table 12 has an open state and a closed state to open or close the first operation port 11b, and the carrier table 12 is in a horizontal state when it closes the first operation port 11b.

[0046] It should be noted that there is a first operation port 11b above the avoidance space 11a. It can be understood that this is described in the state when the auxiliary device 10 for a rotary printing machine is applied to the rotary printing machine 100 and used normally. The carrier table 12 is movably arranged on the base 11. When it is in the open state, it opens the first operation port 11b, and when it is in the closed state, it closes the first operation port 11b. Among them, when the carrier table 12 closes the first operation port 11b, it can be understood that the carrier table 12 covers the first operation port 11b. Since the first operation port 11b is above the avoidance space 11a and the carrier table 12 covers the first operation port 11b when it closes the first operation port 11b, it can be understood that after the auxiliary device 10 for a rotary printing machine is applied to the rotary printing machine 100, the carrier table 12 is located above the loading plate, so that the operator can climb onto the carrier table 12 to perform operations such as replacing the screen plate, wiping the screen plate, and adding slurry on the turntable 30 below. The carrier table 12 is movably arranged on the base 11, so that the carrier table 12 has an open state and a closed state to open or close the first operation port 11b. It can be understood that when the carrier table 12 is in the open state, it opens the first operation port 11b, and when the carrier table 12 is in the closed state, it closes the first operation port 11b. In the embodiments of the present application, the specific movable arrangement manner of the carrier table 12 on the base 11 is not limited. For example, the carrier table 12 can be slidably arranged on the base 11 or can be rotatably arranged on the base 11, but it is not limited to this. The carrier table 12 is in a horizontal state after closing the first operation port 11b and can carry the operator. The carrier table 12 can be circular, rectangular, triangular or polygonal, but it is not limited to this.

[0047] In some embodiments, a second operation port 12c can be provided on the carrier table 12. When the carrier table 12 closes the first operation port 11b, the second operation port 12c is used for the operator on the carrier table 12 to operate on the turntable 30, and the operator can operate on the turntable 30 through the second operation port 12c on the carrier table 12. When the carrier table 12 opens the first operation port 11b, the second operation port 12c is used to avoid the printing head of the rotary printing machine 100, as Figure 2 and Figure 3 shown.

[0048] AsFigure 1 As shown, in some embodiments, the carrying platform 12 has opposite open edges 12a and connecting edges 12b. The connecting edge 12b is hinged to the base 11, so that the carrying platform 12 can be flipped from the open edge 12a to achieve the open state and the closed state. Among them, the connecting edge 12b can be hinged to the base 11 through a hinge, but is not limited thereto. Taking the carrying platform 12 as a rectangle as an example, the open edge 12a and the connecting edge 12b are opposite sides of the carrying platform 12.

[0049] When the carrying platform 12 closes the first operation opening 11b, it is in a horizontal state, so that the operator can climb onto the carrying platform 12 to perform operations such as replacing the screen plate, wiping the screen plate, and adding slurry to the turntable 30. To ensure the stability of the carrying platform 12, the open edge 12a of the carrying platform 12 can be supported by the base 11 after the carrying platform 12 closes the first operation opening 11b. As Figure 5 and Figure 6 As shown, in some embodiments, one of the open edge 12a and the base 11 is provided with a fixed groove 121, and the other is provided with a fixed protrusion 11c that cooperates with the fixed groove 121. After the carrying platform 12 closes the first operation opening 11b, the open edge 12a of the carrying platform 12 and the base 11 can be matched through the fixed groove 121 and the fixed protrusion 11c to ensure the stability of the connection between the open edge 12a of the carrying platform 12 and the base 11, so as to ensure that the carrying platform 12 provides stable support for the operator. In the embodiment of the present application, the example of setting the fixed groove 121 on the open edge 12a and the fixed protrusion 11c on the base 11 is used for illustration. It can be understood that the shapes of the fixed groove 121 and the fixed protrusion 11c correspond to each other. For example, the shapes of the fixed groove 121 and the fixed protrusion 11c can be rectangular, semi-circular or trapezoidal, but are not limited thereto.

[0050] As Figure 3As shown in the figure, in order to further ensure the connection stability between the opening edge 12a of the carrier table 12 and the base 11, in some embodiments, the turntable printing machine auxiliary device 10 further includes a locking assembly 13. The locking assembly 13 includes a threaded column 131 and a locking nut 132 that is threadedly engaged with the threaded column 131. The threaded column 131 is disposed on the end face of the fixed protrusion 11c. Thus, after the locking nut 132 is engaged with the threaded column 131, by turning the locking nut 132, the end face of the locking nut 132 can be brought into close contact with at least one of the end faces of the fixed groove 121, thereby realizing the locking connection between the opening edge 12a of the carrier table 12 and the base 11. Taking the fixed protrusion 11c being disposed on the base 11 and the fixed groove 121 being disposed on the carrier table 12 as an example for illustration, it should be noted that, among them, the end face of the one provided with the fixed groove 121 can be understood as the end face of the carrier table 12. The locking nut 132 being brought into close contact with at least the end face of the fixed groove 121 to lock the base 11 and the carrier table 12 can be that the locking nut 132 is only in close contact with the end face of the fixed groove 121, or the end face of the locking nut 132 is simultaneously in close contact with the end face of the one provided with the fixed groove 121 and the end face of the fixed protrusion 11c. Among them, the locking nut 132 being only in close contact with the end face of the one provided with the fixed groove 121 can be that the end face of the one provided with the fixed groove 121 protrudes from the end face of the fixed protrusion 11c, or the area of the end face of the locking nut 132 that contacts the one provided with the fixed groove 121 protrudes from the area that contacts the fixed protrusion 11c, but is not limited thereto; the end face of the locking nut 132 being simultaneously in close contact with the end face of the one provided with the fixed groove 121 and the end face of the fixed protrusion 11c can be that the area of the end face of the locking nut 132 that contacts the one provided with the fixed groove 121 and the area that contacts the fixed protrusion 11c are flush, and at the same time the end face of the one provided with the fixed groove 121 and the end face of the fixed protrusion 11c are flush, but is not limited thereto.

[0051] When the carrier table 12 is in the open state, the first operation port 11b is opened, and the operator can replace the table paper through the first operation port 11b. As Figure 5 and Figure 6As shown, in some embodiments, a chute 122 is provided on the end face of the carrier table 12. The chute 122 extends along the length direction perpendicular to the opening edge 12a of the carrier table 12, and a first limiting groove 123 is provided at one end of the chute 122 close to the connecting edge 12b, and a second limiting groove 124 is provided at one end of the chute 122 close to the opening edge 12a; correspondingly, the auxiliary device 10 of the rotary press further includes a support rod 14. One end of the support rod 14 is rotatably arranged on the base 11, and the other end is provided with a slider. The slider is slidably arranged in the chute 122 of the carrier table 12. When the slider slides into the first limiting groove 123, the carrier table 12 remains in the closed state, and when the slider slides into the second limiting groove 124, the carrier table 12 remains in the open state. By providing the support rod 14 and providing the corresponding chute 122 on the carrier table 12, when it is necessary to open the first operation port 11b, the slider of the support rod 14 can be slid into the second limiting groove 124, so that the carrier table 12 can be kept in the open state, facilitating the operator to perform the operation of replacing the table paper.

[0052] The base 11 forms an avoidance space 11a. When the auxiliary device 10 of the rotary press is applied to the rotary press 100, the turntable 30 is located in the avoidance space 11a, so that the base 11 supports the carrier table 12 above the turntable 30. As Figure 1 and Figure 2 shown, the base 11 may include a support frame 111, a mounting beam 112 and a lapping frame 113. Among them, two support frames 111 are provided, distributed on opposite sides of the carrier table 12. The mounting beam 112 is lapped between the two support frames 111. The connecting edge 12b of the carrier table 12 is hinged to the mounting beam 112. The lapping frame 113 is arranged on one side of the opening edge 12a of the carrier table 12 for supporting the opening edge 12a, so that the base 11 supports the carrier table 12 above the turntable 30. In some embodiments, the base 11 may further include a strengthening beam 114. The strengthening beam 114 is also lapped between the two support frames 111, and the strengthening beam 114 is located between the mounting beam 112 and the lap. The strengthening beam 114 provides support for the interval between the connecting edge 12b and the opening edge 12a of the carrier table 12, further ensuring the stability of the support of the base 11 for the carrier table 12. Among them, the support frame 111 may be an inverted U-shaped frame, so that the support frame 111 can provide support for both the mounting beam 112 and the strengthening beam 114 at the same time. The wafer feeding conveyor belt 41 and the wafer discharging conveyor belt 42 connecting the turntable 30 in the rotary press 100 can also pass through the support frames 111 on both sides of the turntable 30 respectively.

[0053] It should be noted that the lap frame 113 is used to support the open edge 12a of the carrier platform 12. It can be understood that when the open edge 12a is provided with a fixing groove 121, correspondingly, a fixing protrusion 11c that cooperates with the fixing groove 121 is provided on the lap frame 113; when the rotary printing press auxiliary device 10 also includes a support rod 14, correspondingly, one end of the support rod 14 rotatably provided on the base 11 can also be rotatably provided on the lap frame 113.

[0054] like Figure 1 As shown, in some embodiments, the bridging frame 113 is further formed with an operation window 113a, and a protective window 113b is provided at the operation window 113a. The protective window 113b may be a transparent window, so that the operator can observe the printing of the silicon wafer on the turntable 30 through the protective window 113b. The protective window 113b may be rotatably provided at the operation window 113a through a hinge, or may be detachably provided at the operation window 113a, so that other operations may be performed on the turntable 30 or the silicon wafer on the turntable 30 from the operation window 113a by opening or removing the protective window 113b.

[0055] like Figure 2 and Figure 3 As shown, in some embodiments, the present application further provides a rotary disk printer 100, which includes a printing head 20, a rotary disk 30, and a rotary disk printer auxiliary device 10 provided in any of the above embodiments. Among them, the printing head 20 is used to print the silicon wafer on the rotary disk 30. It can be understood that a silicon wafer feeding conveyor belt 41 and a silicon wafer discharge conveyor belt 42 are respectively arranged on opposite sides of the rotary disk 30. The silicon wafer feeding conveyor belt 41 is used to transport the silicon wafer to be printed to the rotary disk 30, and the silicon wafer discharge conveyor belt 42 is used to transport the printed silicon wafer to the next process. The rotary disk 30 is located in the avoidance space 11a of the rotary disk printer auxiliary device 10, and correspondingly, the carrier 12 is located above the rotary disk 30. It should be noted that, when the turntable 30 is located in the avoidance space 11a of the turntable printing press auxiliary device 10, the turntable 30 may be completely located in the avoidance space 11a, or the edge area of ​​the turntable 30 may protrude from the side of the base 11 to the avoidance space 11a. For example, the edge area of ​​the turntable 30 may protrude from the avoidance space 11a from the gap between the two support frames 111 on the side of the base 11, between the two support legs of each support frame 111, and between the support frame 111 and the bridging frame 113.

[0056] In some embodiments, in a rotary printing press, the carrier table 12 can cover a part of the rotary table, which facilitates operations such as replacing the screen plate, wiping the screen plate, and adding paste under the carrier table 12 for the operator. When the carrier table 12 has opposite open sides 12a and connecting sides 12b, and the connecting side 12b is hinged to the base 11, the printing head 20 of the rotary table 30 printing press can be located on the side of the carrier table 12 close to the connecting side 12b, which can facilitate the opening and closing operations of the carrier table 12 and avoid the carrier table 12 affecting the printing head 20 during the opening or closing process.

[0057] The rotary table printing press 100 provided in this application adopts all the technical solutions of all the embodiments of the above-mentioned rotary table printing press auxiliary device 10. Therefore, it has at least all the beneficial effects brought by the technical solutions of the embodiments of the above-mentioned rotary table printing press auxiliary device 10, which will not be elaborated here one by one.

[0058] The above is only the implementation mode of this application, and does not limit the patent scope of this application.
