[0030] Figures 1 to 4 An embodiment of the screen printing device of the present application is schematically shown.

[0031] As Figures 1 to 4 shown, the present application discloses a screen printing device, which includes: a base fixture 1, on which a cavity 11 for screen printing products is provided. Open break slots 12 are symmetrically arranged on both sides of the cavity 11, and the product is suspended at the position of the break slots 12. A pick-and-place fixture 2, which includes a left fixture 21 and a right fixture 22 that can be opened and closed. The left fixture 21 and the right fixture 22 can respectively extend into both sides of the cavity 11 along the break slots 12 to lift the bottom surface of the product for picking and placing the product.

[0032] Through the above structural design, in the present application, by providing the break slots 12 on the base fixture 1, the screen printing product can be partially suspended, and a pick-and-place fixture 2 that can be opened and closed is provided to extend into the break slots 12 to lift and pick up the product from the bottom surface, avoiding contacting the front surface of the product during the picking and placing process and not soiling the ink area on the front surface of the product. It has a wider application range, and the lifting and picking method is more secure, which can avoid the risk of the product falling due to insufficient adsorption.

[0033] In some embodiments of the present application, as Figures 1 to 3 shown, in the pick-and-place fixture 2, the left fixture 21 and the right fixture 22 are symmetric structures, which can be rotatably connected through a rotating shaft 26 to form a symmetric opening and closing structure similar to scissors, and the product is lifted and picked up through left and right opening and closing. It has strong scalability and less limitation on the product specifications to which it is applied.

[0034] Refer to Figure 2 and Figure 3As shown, both the left jig 21 and the right jig 22 include: a pivot section 23, a space section 24, and an inner support section 25 that are connected in sequence from top to bottom. The pivot section 23 is rotatably connected through a rotating shaft 26 to achieve the connection and opening / closing of the left jig 21 and the right jig 22. The space section 24 is bent to form a space for avoiding the product, so as to prevent contacting the upper front surface of the product during picking and placing, and avoid problems such as dirt. The inner support section 25 is protruded upward to lift the product from the bottom surface of the product to achieve the picking and placing of the product.

[0035] In some embodiments of the present application, to improve the stability and reliability of the picking and placing jig 2 for picking up the product, an anti-slip structure (not shown) is further provided on the top surface of the inner support section 25 to increase the friction force and contact area between the inner support section 25 and the product.

[0036] In some embodiments of the present application, the anti-slip structure can be anti-slip grooves or anti-slip pads.

[0037] In some embodiments of the present application, refer to Figure 2 and Figure 3 As shown, the pivot section 23, the space section 24, and the inner support section 25 are an integrally formed structure, which is convenient for manufacturing and has a firm structure.

[0038] In some embodiments of the present application, the base jig 1 and the picking and placing jig 2 can be made of the same material, such as bakelite, or can also be made of different materials, such as metal, etc.

[0039] In some embodiments of the present application, as Figure 4 shown, a plurality of suction holes 13 are evenly distributed at the bottom of the cavity 11 of the base jig 1. The suction holes 13 are used to connect a suction device to improve the fixing stability of the product during the screen printing operation by adsorption and improve the screen printing quality.

[0040] In some embodiments of the present application, as Figure 4 shown, an avoidance sinking groove 14 is provided at the bottom of the cavity 11. The avoidance sinking groove 14 divides the bottom of the cavity 11 into multiple support areas 15. By providing the avoidance sinking groove 14, the direct contact area between the base jig 1 and the product can be reduced, problems such as scratches caused by friction can be reduced, and products such as glass covers can be protected. At the same time, the bottom of the cavity 11 can be divided into multiple support areas 15 to provide multi-point support for the product to be screen printed and improve the support stability.

[0041] In some embodiments of the present application, as Figure 4As shown, the avoidance sinking groove 14 includes a longitudinal groove 141 arranged in the first direction and a plurality of transverse grooves 142 arranged in the second direction, and the first direction is perpendicular to the second direction. Each transverse groove 142 intersects the longitudinal groove 141 at equal intervals, evenly dividing the bottom of the cavity 11 into multiple supporting areas 15. Suction holes 13 are distributed on each supporting area 15, realizing multi-point support and adsorption, improving the position stability of the product during the screen printing operation, and improving the quality of the ink layer after screen printing.

[0042] In some embodiments of the present application, as Figure 4 shown, in the base fixture 1, a chamfer buffer area 16 is provided at the corner of the cavity 11 to improve the protection of the product at right-angled bends and the like.

[0043] In some embodiments of the present application, a plurality of sets of break grooves 12 are symmetrically opened on both sides of the cavity 11 of the base fixture 1. Correspondingly, for each set of break grooves 12 of the pick-and-place fixture 2, a set of left fixtures 21 and right fixtures 22 are respectively provided, so as to realize the pick-and-place of the product at multiple positions, improving the stability of lifting the product. Among them, each set of left fixtures 21 and right fixtures 22 can be connected in series and rotated through the same rotating shaft 26 to be arranged along the same straight line, and lift the product simultaneously from different positions in the length direction of the product, improving the stability of pick-and-place.

[0044] In some embodiments of the present application, the rotating shaft 26 used for the pivot section 23 of the pick-and-place fixture 2 is a rotating shaft 26 with end caps at both ends, so as to stably connect the left fixture 21 and the right fixture 22 together and prevent them from coming out. In some places with low requirements, a bolt can also be directly used as the rotating shaft 26, and the left fixture 21 and the right fixture 22 are limited by the thread of the bolt to prevent them from coming out and separating from each other.

[0045] In some embodiments of the present application, the pivot section 23 of the pick-and-place fixture 2 is also provided with a handle to facilitate manual operation, making it as convenient to open and close as using scissors, so as to extend to the lower part of the product through the break groove 12 and lift the product from the bottom to realize the pick-and-place of the product.

[0046] In some embodiments of the present application, as Figure 2 and Figure 3 shown, in the pick-and-place fixture 2, the space section 24 is a right-angled bending structure, forming a rectangular avoidance space. Specifically, the space section 24 includes an upper section and a lower section arranged horizontally, and a middle section arranged vertically. The middle section connects the upper and lower ends, and the length of the middle section is not less than a preset length to ensure that enough avoidance space is formed, avoiding contacting the front surface of the product and preventing ink layer contamination and damage. In addition, as Figure 2 and Figure 3As shown, the length of the upper part of the space section 24 is greater than that of the lower part. Thus, when the left fixture 21 and the right fixture 22 are opened and closed to the minimum extent, there is still an appropriate gap in the inner support section 25 connected below the space section 24. On the one hand, this can ensure that there is always a certain distance between the lifting points where the two inner support sections 25 contact the product, so as to ensure the stability of lifting and placing the product. On the other hand, it can also leave a bottom avoidance space, making it more convenient to operate when the pick-and-place fixture 2 cooperates with the base fixture 1 and structures such as the baking tray.

[0047] Reference Figure 1 As shown, the working principle of this application is introduced:

[0048] First, the product can be lifted and transferred to the base fixture 1 by the pick-and-place fixture 2. Then, the left fixture 21 and the right fixture 22 are opened away from each other, allowing the product to fall into the cavity 11 of the base fixture 1, and the suction device below the base fixture 1 is turned on to adsorb and fix the product through the suction holes 13 to stabilize the position of the product for silk-screen printing operation. After the silk-screen printing operation is completed, the pick-and-place fixture 2 is used again to open the left fixture 21 and the right fixture 22, and they are respectively extended into the break grooves 12 on both sides of the base fixture 1, contact the product from the bottom surface of the suspended position of the product, and lift the product upward. It can be understood that during the upward lifting process, the left fixture 21 and the right fixture 22 can be continuously closed towards each other to make the inner support section 25 fit more closely with the bottom surface of the product. Finally, the product is transferred to equipment such as a baking tray, and by opening the left fixture 21 and the right fixture 22, the product is transferred into the baking tray for baking and fixing the ink layer. During the whole process, the pick-and-place fixture 2 does not come into contact with the front surface of the product, will not dirty or damage the ink layer on the front surface of the product, protects the safety of the ink structure of the product, and at the same time, the lifting and placing method is more firm, not easy to cause the product to fall, and reduces the risk of product damage.

[0049] In summary, the silk-screen printing equipment of this application includes: a base fixture and a pick-and-place fixture. The base fixture is provided with a cavity for silk-screen printing the product, and open break grooves are symmetrically arranged on both sides of the cavity, and the product is suspended at the position of the break grooves; the pick-and-place fixture includes a left fixture and a right fixture that can be opened and closed, and the left fixture and the right fixture can respectively extend into both sides of the cavity along the break grooves to lift the bottom surface of the product for picking and placing the product. By setting break grooves on the base fixture in this application, the silk-screen printed product can be partially suspended, and a pick-and-place fixture that can be opened and closed is set to extend into the break grooves to lift and place the product from the bottom surface, avoiding contact with the front surface of the product during the picking and placing process, not dirtying the ink area on the front surface of the product, having a wider application range, and the lifting and taking method is more firm, which can avoid the risk of the product falling due to insufficient adsorption.

[0050] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application.
