[0029] like Figure 1-Figure 5As shown, the utility model provides a keyboard silk screen production line, characterized in that it comprises: a workbench 10, a conveying track 20 is arranged in a surrounding shape on the workbench 10, a first silk screen device 30 is arranged at a first end of the workbench 10, a second silk screen device 36 is arranged at a second end of the workbench 10 opposite to the first silk screen device 30, a first drying device 50 is arranged on a first side of the workbench 10, a second drying device 55 is arranged on a second side of the workbench 10 opposite to the first side, the first drying device 50 and the second drying device 55 cover the conveying track 20 at corresponding positions, a pad printing device 40 is further arranged at one end adjacent to the first silk screen device 30, a plurality of spaced conveying disc assemblies 24 are drivingly connected to the conveying track 20, and the conveying disc assembly 24 passes through the first silk screen device 30, the pad printing device 40, the first drying device 50, the second silk screen device 36, and the second drying device 55 in sequence along the conveying track 20 from a predetermined position;

[0030] Specifically, the conveying track 20 is in a closed loop shape, and a first silk screen printing device 30 for printing a first feature, a pad printing device 40 for printing a brand and other features, a first drying device 50 for accelerating the curing of the aforementioned printed features, a second silk screen printing device 36 for printing a second feature, and a second drying device 55 for curing the aforementioned printed features for a second time are sequentially provided in the conveying direction of the conveying track 20. When the conveying tray assembly 24 moves on the sample conveying track 20, it passes through the aforementioned devices in sequence and completes a whole set of processing at one time without manual transfer and automatic processing. A whole set of processing equipment can be installed in a limited space to maximize the use of space and reduce space requirement costs. In addition, multiple conveying tray assemblies 24 can be installed at the same time according to demand, so that multiple products can be processed simultaneously but with different requirements, greatly improving processing efficiency.

[0031] Among them, the conveying track 20 includes: a slide rail 21, which is in a closed loop shape, and a transmission chain 22 is provided on the inner side of the slide rail 21, and two driving wheels 23 are respectively provided at the first end and the second end of the workbench 10. The driving wheels 23 are connected to the transmission chain 22 for transmission. The driving wheels 23 can be driven by a motor to generate a driving force to drive the transmission chain 22 to move. At the same time, the conveying disc assembly 24 is connected to the transmission chain 22. When the transmission chain 22 moves, it drives the conveying disc assembly 24 to move along the slide rail 21 to realize the transportation of the product. The driving wheels 23 can choose two diagonally set motors, and the other two diagonally set driving wheels 23 can be used as driven wheels and support the transmission chain 22.

[0032] Each conveyor tray assembly 24 includes: at least two sliding bases 25, and the bottom of each sliding base 25 is provided with a slide 26 that slides with the slide rail 21. In order to prevent the sliding base 25 from falling out of the slide rail 21, the slide 26 and the slide rail 21 preferably adopt a concave-convex embedded sliding fit to prevent the slide 26 from moving vertically; in order to facilitate the placement of products, a mounting plate 27 is rotatably connected above the two sliding bases 25. The rotation method can avoid movement conflicts due to the corners of the conveying track 20, so that the mounting plate 27 can smoothly pass through the corners of the conveying track 20.

[0033] Furthermore, the first screen printing device 30 includes: a screen printing lifting device 31, a screen printing transverse movement device 32, the screen printing lifting device 31 is fixed in the workbench 10, the screen printing lifting device 31 adopts a screw transmission method to drive the screen printing transverse movement device 32 to move up and down, which is an existing technology, so it will not be described in detail here, the screen printing transverse movement device 32 adopts a motor and a transmission belt method to realize the lateral movement of the scraper 35, which is an existing technology, so it will not be described in detail here, and printing brackets 33 are adjustable at both ends of the screen printing transverse movement device 32. A printing table 34 is connected between the two printing brackets 33, and a predetermined printing plate and ink are provided on the printing table 34. The scraper 35 is used to control the printing table 34 to descend when the product is transported to the bottom of the printing table 34, so that it is in contact with the upper surface of the product, and then the scraper 35 is driven by the screen printing transverse movement device 32 to move from one end to the other end on the printing table 34, squeezing the ink on the product during the movement to achieve characteristic printing. The second screen printing device 36 differs from the first screen printing device 30 in the content of the printing plate, while other structures are the same.

[0034] Furthermore, the pad printing device 40 includes: a pad printing mounting seat 41, which is fixedly arranged in the workbench 10, and a pad printing mounting plate 42 is fixedly arranged above the pad printing mounting seat 41, and a pad printing transverse moving device 43 is arranged above the pad printing mounting plate 42. The pad printing transverse moving device 43 is driven by a cylinder and a slider, and a pad printing lifting device 44 is connected to the pad printing transverse moving device 43. The pad printing transverse moving device 43 can control the extension distance of the pad printing lifting device 44. The pad printing lifting device 44 is driven by a cylinder and a guide column, and a pad printing head 45 is connected to one end of the pad printing lifting device 44. When the product moves to the bottom of the pad printing device 40, the pad printing lifting device 44 controls the lifting and lowering of the pad printing head 45 to print the features on the product. The pad printing device 40 is usually used to print smaller features such as brands and LOGOs.

[0035] Furthermore, the first drying device 50 includes: an oven 51 covered above the conveying track 20, and entrances and exits are provided at the front and rear ends of the oven 51 so that the product can enter the oven 51.

In order to avoid the accumulation of exhaust gas in the oven 51, a heat exhaust pipe 54 is also provided on the top of the oven 51, and an exhaust fan is provided in the heat exhaust pipe 54 to accelerate the discharge of exhaust gas in the oven 51.

[0036] The second drying device 5555 has the same structure as the first drying device 50, so it will not be described in detail here.

[0037] To sum up, the present application uses a surrounding conveyor track. When the conveyor disc assembly moves along the conveyor track, it passes through each process device in sequence and completes a whole set of processing at one time. There is no need for manual transfer and automated processing. A whole set of processing equipment can be installed in a limited space to maximize the use of space and reduce space requirement costs. In addition, multiple conveyor disc assemblies can be installed at the same time according to demand, so that multiple products can be processed at the same time but with different requirements, greatly improving processing efficiency.
