[0002] Industrial printing is an important process, which is to print ink on the product to give the product surface decorative printing or functional printing. Among them, mobile phone glass, display, wearable electronics and other products often achieve the above process through silk screen printing. When printing the product, it is necessary to ensure the cleanliness of the product surface to avoid dust and other impurities adhering to the product surface affecting the product printing effect. Therefore, the surface of the product needs to be cleaned before printing.

[0003] In the prior art, such as a mobile phone glass processing screen printing machine with application number 202321751226.6, it discloses a cleaning clamping assembly, a vertical clamping plate of a spring contacts with the glass plate to fix the glass plate, and the first motor is turned on to rotate the screw to move the rectangular sleeve block sleeved on its outer surface, thereby driving the glass plate on the concave plate to move. When it moves to the bottom of the first gantry, the electric telescopic rod is turned on to move the moving plate downward so that the cleaning plate contacts with the glass plate to clean its surface. The process is that the glass plate moves while the cleaning plate is relatively fixed, and the glass plate is fixed by components such as springs. During the process of the glass plate being driven to move, the surface contact formed with the cleaning plate (sponge at the lower end) may also cause the position of the glass plate to be unstable; in addition, during the movement of the glass plate to the bottom of the printing mechanism, its feeding process also needs to adapt to the cleaning action of the cleaning assembly, which may also cause the feeding of the glass plate to be not smooth.

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figures 1 to 2As shown, a front treadmill screen printing device includes a machine platform 10, and a printing mechanism 20, a linear module 30, a treadmill 40 and a cleaning mechanism 50 arranged on the machine platform 10. The linear module 30 is arranged on the machine platform 10 and one end is located beside the printing mechanism 20. The treadmill 40 is arranged at the output end of the linear module 30 for carrying the product to be screen printed. The treadmill 40 can be driven by the linear module 30 to move to the bottom of the printing mechanism 20. The cleaning mechanism 50 includes a gantry 52, a lifting unit 53, a cleaning unit Element 54 and a translation unit 55, guide rail pairs 51 are respectively provided on both sides of the linear module 30 on the machine 10, the bottom ends of both sides of the gantry 52 are arranged on the guide rail pairs 51, and are connected to the translation unit 55, the lifting unit 53 can be a lifting cylinder, which is arranged on the gantry 52, and a cleaning unit 54 is provided at the output end, the cleaning unit 54 is driven by the lifting unit 53 to move down close to or abut against the product on the treadmill 40, and is driven by the translation unit 55 to move on the upper surface of the product to clean the product.

[0028] In the present invention, the product is placed on the treadmill 40, and the product can be positioned and adsorbed on the treadmill 40 to ensure a stable position. Before the treadmill 40 drives the product to move to the bottom of the printing mechanism 20 after being driven by the linear module 30, the lifting unit 53 drives the cleaning unit 54 to move down and abut against the surface of the product, and is driven by the translation unit 55 so that the cleaning unit 54 moves on the surface of the product to clean it. After the cleaning mechanism 50 completes the cleaning action, it resets, and the linear module 30 drives the treadmill 40 to drive the product to perform a printing action below the printing mechanism 20.

[0029] The utility model can clean the surface of the product positioned on the treadmill 40 by setting up the cleaning mechanism 50, improve its cleanliness, and ensure the printing quality of the product; moreover, the lifting unit 53 and the translation unit 55 in the cleaning mechanism 50 cooperate to drive the cleaning unit 54 to clean the product, and the translation unit 55 is matched and moved according to its range of action and the size of the product, that is, the product is fixed and the translation unit 55 drives the cleaning unit 54 to move back and forth, which can avoid driving the product to move back and forth by the treadmill 40 to clean the product, thereby ensuring the independence of the work of each mechanism.

[0030] Continue as Figure 2 As shown, further, the translation unit 55 includes a motor 551, a driving wheel 552, a driven wheel 553, a transmission belt 554 and a connecting plate 555. The motor 551 is arranged on the machine 10, and the output end is provided with a driving wheel 552. The driven wheel 553 is arranged on the machine 10, and the outer side of the driving wheel 552 is provided with a transmission belt 554. The connecting plate 555 connects the transmission belt 554 and the gantry 52, and the movement of the transmission belt 554 drives the connecting plate 555 and the gantry 52 to move.

[0031] like Figure 3 As shown, guide grooves 520 are symmetrically provided on a pair of vertical plates 521 on the gantry 52, and the end of the cleaning unit 54 is embedded in the guide groove 520 and connected to the lifting unit 53. The lifting unit 53 can drive the end of the cleaning unit 54 to rise or fall in the guide groove 520 so that the cleaning unit 54 is away from or abuts against the product. On the one hand, the guide groove 520 provides a clearance space for the end of the cleaning unit 54 to extend out of the vertical plate 521 and connect with the lifting unit 53, and on the other hand, it can also limit the moving trajectory of the cleaning unit 54.

[0032] Furthermore, the cleaning unit 54 includes a dust removal roller 541 and a dust sticking roller 542. Both ends of the dust removal roller 541 extend out of the guide groove 520 and are connected to the output end of the lifting unit 53. The dust sticking roller 542 abuts against the upper end of the dust removal roller 541, and both ends are embedded in the guide groove 520, that is, the dust removal roller 541 is fixedly connected to the lifting unit 53, and the sticking roller 542 is only abutted against the dust removal roller 541 through the limiting effect of the guide groove 520 in the vertical direction, which can complete the line contact between the two to realize the transfer of dust after dust removal on the product surface (adhered to the sticky roller 542), and can also facilitate the disassembly and installation of the sticky roller.

[0033] Based on the above arrangement, the upper portion of the guide groove 520 has a corner structure, which can prevent the dust-sticking roller 542 from vertically detaching from the guide groove 520 due to being lifted by the dust-removing roller 541, thereby ensuring the connection stability between the dust-sticking roller 542 and the dust-removing roller 541.

[0034] In addition, a sealing plate 522 covering the upper part of the guide groove can be provided on the gantry 52. ​​The existence of the sealing plate 522 does not affect the action of the lifting unit 53, and the linear contact length between the sticky roller 542 and the dust removal roller 541 can be ensured by limiting the two ends of the sticky roller 542, thereby ensuring the effective transfer of dust.

[0035] like Figure 4 As shown, the printing mechanism 20 includes a lifting module 21, an X-axis module 22, a Z-axis module 23 and a printing unit. The lifting module 21 is arranged on the machine table 10, and the output end is provided with an X-axis module 22. The Z-axis module 23 is arranged at the output end of the X-axis module 22. The printing unit includes a printing head 24 and a screen 2b. The printing head 24 is arranged on the Z-axis module 23, which includes a scraper assembly and an ink return knife assembly. A pair of clamping parts 2a are provided on the shell of the X-axis module 22. The pair of clamping parts 2a can adjust the distance between the two laterally respectively. The two ends of the screen 2b are respectively arranged on the pair of clamping parts 2a. The lifting module 21 drives each component to move downward so that the screen 2b abuts against the upper surface of the product on the running platform 40. The Z-axis module 23 drives the printing head 24 to abut against the upper surface of the screen 2b. The printing action is completed by driving the printing head 24 to move back and forth through the X-axis module 22.

[0036] like Figure 5 As shown, the front treadmill screen printing device also includes a visual mechanism 60, which is arranged on the machine platform 10 and is located above the linear module 30 on a side away from the printing mechanism 20 and close to the cleaning mechanism 50. The visual mechanism 60 includes a support rod 61, a Y guide rail 62 and an X guide rail 63. A pair of support rods 61 are arranged on the machine platform 10, a pair of Y guide rails 62 are respectively arranged on a pair of support rods 61, and a plurality of X guide rails 63 are slidably arranged on the pair of Y guide rails 62 in parallel, and a plurality of CCD camera modules 64 are slidably arranged thereon. By setting the CCD camera module, the position of the product placed on the treadmill 40 can be identified, for example, the midpoint position of the four sides of the square product can be identified, which can be used to detect whether the position of the product is deviated after being acted upon by the cleaning mechanism 50. Shift; moreover, the position of each CCD camera module 64 can be relatively adjusted by setting the Y guide rail 62 and the X guide rail 63, that is, the position of each CCD camera module 64 can be moved in two vertical directions in the horizontal plane to adapt to products of different sizes, and the X guide rail 63 and the CCD camera module 64 are respectively provided with positioning locking members, for example: the end of the X guide rail 63 is locked to the Y guide rail 62 by a first locking plate 631 and a first bolt 632 passing through the first locking plate 631, and the CCD camera module 64 is locked to the X guide rail 63 by a second locking plate 641 and a second bolt 642 passing through the second locking plate 641, so as to achieve the stability of the position of the CCD camera module 64 after adjusting the position of the CCD camera module 64.
