To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0030] Below, please refer to the appendix. Figure 1 and Figure 2 The auxiliary device for screen printing according to this application is provided at the feeding end of the screen printing equipment. The auxiliary device includes a support member 300, on which a driving member 200 is provided. A push plate 100 is provided at one end of the driving member 200. An airflow channel is provided inside the push plate 100. At least one air blowing hole 1011 is provided on the surface of the push plate 100 facing the basket. The driving member 200 drives the push plate 100 to reciprocate, so that the push plate 100 guides and blows air onto the basket containing the silicon wafer.
[0031] The pusher plate 100 can be a split structure or a one-piece structure. The pusher plate 100 is a rectangular plate with a flat surface. When the drive unit 200 drives the pusher plate 100 to the silicon wafers in the basket, the pusher plate 100 can guide the irregularly arranged silicon wafers into a regular shape, making them neatly arranged. The pusher plate 100 has an internal cavity, and at least one air hole 1011 is provided on the surface of the pusher plate 100 facing the basket. By providing an internal cavity within the pusher plate 100, airflow, such as compressed air, can enter the pusher plate 100 and be blown out through the air hole 1011, thereby effectively removing incoming material dust and other foreign objects from the silicon wafers in the basket.
[0032] This application, by setting up a screen printing auxiliary device at the feeding end of the screen printing process, can not only effectively adjust the position of the silicon wafers in the basket and guide the silicon wafers to be placed neatly, but also blow away the silicon wafers in the basket at the same time, avoiding abnormal shutdowns caused by incoming material dust and foreign objects, thereby increasing production line capacity and reducing product defects.
[0033] In one alternative approach, such as Figure 3 As shown, the pusher plate 100 includes a plurality of air holes 1011, which are rectangularly arranged on the surface of the pusher plate 100. Preferably, the plurality of air holes 1011 are symmetrically arranged in a rectangular shape on the surface of the pusher plate 100, thereby providing a more uniform airflow to effectively remove foreign matter such as incoming material dust from the silicon wafer.
[0034] In some specific embodiments, the diameter of the air inlet 1011 is 1-2 mm; for example, it can be 1 mm, 1.5 mm or 2 mm.
[0035] In some specific embodiments, the air inlet 1011 is circular, near-circular, elliptical, or waist-shaped.
[0036] In one alternative approach, such as Figure 3 As shown, the pusher plate 100 includes two opposing inner plates 102 and outer plates 101. The inner plates 102 are away from the flower basket, and the outer plates 101 are close to the flower basket. An air blowing hole 1011 is provided on the outer plate 101, and an air inlet hole 1014 is provided on the inner plate 102. Thus, the pusher plate 100, which can be blown and guided, can be easily and conveniently manufactured by the arrangement of the inner and outer plates 101.
[0037] In some specific embodiments, such as Figure 3 As shown, a groove 1021 is provided on the surface of the inner plate 102 opposite to the inner plate 102, and an air inlet 1014 is provided in the groove 1021. The position of the groove 1021 corresponds to the air blowing hole 1011 on the outer plate 101. This allows for better airflow to be blown out, removing dust and other foreign objects from the surface of the silicon wafer.
[0038] In a specific embodiment, such as Figure 3As shown, the groove 1021 includes at least one n-shaped groove 1021, which corresponds to the rectangular space formed by the air blowing hole 1011. This allows for better removal of dust and other foreign matter from the silicon wafer surface.
[0039] In one specific embodiment, the width of the groove 1021 is 4-5mm; for example, it can be 4mm, 4.5mm or 5mm; the depth is 4-5mm; for example, it can be 4mm, 4.5mm or 5mm; thereby, foreign objects such as dust on the surface of the silicon wafer can be removed more effectively.
[0040] In an alternative embodiment, the inner panel 102 and the outer panel 101 are provided with a first connecting hole 1012 for connecting the inner panel 102 and the outer panel 101. The first connecting hole 1012 is located within the rectangular space enclosed by the air hole 1011. This allows for better securing of the inner panel 102 and the outer panel 101.
[0041] In an alternative embodiment, the inner plate 102 and the outer plate 101 are provided with second connecting holes 1013 for connecting the drive component and the push plate. The second connecting holes 1013 are located within the rectangular space enclosed by the air holes 1011. This allows for better connection with the drive component.
[0042] In one alternative approach, such as Figure 3 As shown, the driving component 200 is a cylinder.
[0043] In one alternative approach, such as Figure 3 As shown, the support member 300 includes a column 302, a leg 301, and a mounting plate 303; the leg 301 is located below the column 302 and is fixedly connected to the column 302; the mounting plate 303 is fixedly located above the column 302, and the mounting plate 303 is fixedly connected to the drive member 200 through the bracket 400.
[0044] In one alternative embodiment, the auxiliary device further includes a PLC control system for controlling the drive unit 200 and the push plate 100.
[0045] The second aspect of this application also provides a screen printing apparatus, including a screen printing auxiliary device provided in the first aspect of this application.

[0048] The support component 300 includes a column 302, a leg 301, a mounting plate 303, and a bracket 400; the leg 301 is located below the column 302 and is fixedly connected to the column 302; the mounting plate 303 is fixedly located above the column 302, and the mounting plate 303 is fixedly connected to the drive component 200 through the bracket 400.
[0049] Drive component 200 is a cylinder.
[0050] The push plate 100 includes two opposing inner plates 102 and outer plates 101. The inner plates 102 are away from the flower basket, and the outer plates 101 are close to the flower basket. The outer plate 101 of the push plate 100 has multiple circular air holes 1011 with a diameter of 1 mm. These air holes 1011 form two rectangular shapes symmetrically arranged at the upper and lower ends of the outer plate 101. First connecting holes 1012 are also provided on the inner plates 102 and outer plates 101 for connecting them. Two first connecting holes 1012 are provided within the rectangular space enclosed by each air hole 1011. Second connecting holes 1013 are also provided on the inner plates 102 and outer plates 101 for connecting the drive component and the push plate. Four second connecting holes 1013 are located between the rectangular spaces enclosed by the air holes 1011. The inner plate 102 of the push plate 100 has two n-shaped grooves 1021, each n-shaped groove 1021 corresponding to a rectangular space formed by an air blowing hole 1011. The back of the inner plate 102 of the push plate 100 has an air inlet 1014, which is connected to a compressed air source. The middle of the push plate 100 has a connection hole 103 for connecting to the drive component 200.
[0051] The PLC control system is connected to the drive unit 200 and the compressed air source, and is used to control the drive unit 200 and the push plate 100.

When the basket moves to the predetermined position of the feeding platform of the screen printing device, the PLC controls the cylinder to push the push plate 100 to contact the side wall of the basket to guide the silicon wafer. At the same time, the compressed air source connected to the push plate 100 supplies air to the groove 1021 of the push plate 100 through the air inlet 1014 1012 of the push plate 100. The airflow is sprayed out through the blowing hole 1011 and the second large hole 1012 outside the push plate 100 to remove dust and other foreign matter impurities from the surface of the silicon wafer.
