Description

Technical Field

[0001] The utility model relates to the technical field of glass screen printing, in particular to a workpiece transfer device of a glass screen printing machine. Background Art

[0002] Glass screen printing machine is used to print patterns on the surface of glass to increase the aesthetics of glass products. Glass screen printing machine generally includes material box, workpiece transfer device and screen printing device. By placing the glass on the screen printing platform of the screen printing device, the corresponding pattern is printed on the glass using the printing component in the screen printing device. The workpiece transfer device is used for loading and unloading and transferring the workpiece to the designated position of the next process after completing one process.

[0003] The existing technology has the following shortcomings: when the existing glass screen printing machine prints patterns on the surface of the glass workpiece, in order to ensure that the printed pattern is more uniform and clear, the screen printing device is usually set on the top surface of the glass workpiece, and the top surface of the glass workpiece is close to the screen printing device during the printing process; therefore, when using a gripping type transfer device such as a robotic arm or a gripping suction cup, it is necessary to move or flip up the screen printing device before the glass workpiece can be transferred to the specified position, which increases the operation steps and affects the working efficiency of the glass screen printing machine. In addition, when the gripping type transfer device grabs the glass workpiece, it may cause scratches or smears on the surface of the glass workpiece, resulting in damage to the printing quality of the product; if a lifting transfer device such as a conveyor belt is used, although the operation steps of flipping up the screen printing device can be reduced, since the conveyor belt can only transport the glass workpiece on a single plane, after the screen printing device is completed, the traditional conveyor belt device cannot separate the top surface of the glass workpiece from the bottom of the screen printing device. Therefore, during the process of conveying the blanking material, the pattern just printed may be scratched, which greatly affects the production printing quality of the glass screen printing machine.

[0004] Therefore, it is necessary to invent a workpiece transfer device for a glass screen printing machine. Utility Model Content

One end of the transmission roller 11 is fixedly connected to the motor, and a conveyor belt 13 is sleeved and installed between the transmission rollers 11 on both sides. The four corners of the base plate 18 are fixedly installed with columns 17, and the upper ends of the columns 17 extend upward to above the base plate 18. The upper ends of the columns 17 are fixedly installed with a glass screen printing machine 4. A loading box 14 is provided on one side of the glass screen printing machine 4, and the loading box 14 is installed above the conveyor belt 13. A glass substrate 3 is placed in the loading box 14. A support plate device is provided on the top surface of the base plate 18. When the glass substrate 3 is transported to the bottom of the glass screen printing machine 4 along the conveyor belt 13, the support plate device can lift the glass substrate 3 so that it is close to the bottom surface of the glass screen printing machine 4.

[0023] In the above embodiment, it should be noted that the glass substrate 3 is placed on the surface of the conveyor belt 13 through the loading box 14, and the motor is started to drive the transmission roller 11 to drive the conveyor belt 13 to rotate. The glass substrate 3 is transported to the bottom of the glass screen printing machine 4 along the conveyor belt 13. The glass substrate 3 is lifted up by the support plate device so that it is close to the bottom surface of the glass screen printing machine 4. Then, the glass screen printing machine 4 is started to complete printing, and then the glass substrate 3 is driven to sink away from the glass screen printing machine 4, so as to achieve the effect of simplifying the loading and unloading steps of the glass substrate 3, improve the working efficiency of the glass screen printing machine 4, avoid scratches on the surface of the glass substrate 3, and prevent the printed pattern from being scratched, thereby greatly improving the production and printing quality of the glass screen printing machine.

[0024] Example 2

[0025] like Figure 1 - Figure 5 As shown, a workpiece transfer device for a glass screen printing machine includes all the contents of Example 1. In addition, the support plate device includes a support plate 20, and hydraulic rods 19 are fixedly installed at the four corners of the bottom surface of the support plate 20. The lower end of the hydraulic rod 19 is fixedly connected to the top surface of the base plate 18. The two sides of the support plate 20 extend upward and wrap the bottom surface and both sides of the conveyor belt 13. Openings are provided at both ends of the two sides of the upwardly extending support plate 20 that are close to each other. The support plate device includes contacts 21, and the contacts 21 are slidably installed in the openings on both sides of the upwardly extending support plate 20. A spring 22 is installed at one end of the contact 21 close to the bottom surface of the opening, and a pressure sensor is installed at the end of the spring 22 away from the contact 21. The support plate device includes a control terminal 23, and the control terminal 23 is fixedly installed in the center of the top surface of the base plate 18. The control terminal 23 is electrically connected to the pressure sensor in the opening of the support plate 20.

[0026] In the above embodiment, it should be noted that when the glass substrate 3 is conveyed to the bottom of the glass screen printing machine 4 along the conveyor belt 13, the two sides of the glass substrate 3 will move between the two sides of the upwardly extending support plate 20. At the same time, the two sides of the glass substrate 3 will squeeze the contacts 21 and the spring 22. The pressure sensor detects the pressure signal and sends it to the control terminal 23. After all the pressure sensors detect the pressure signal, the control terminal 23 determines that the glass substrate 3 has completely entered the upper part of the support plate 20. Finally, the control terminal 23 controls the hydraulic rod 19 to start and lift the support plate 20, so as to achieve the effect of supporting the glass substrate 3 close to the glass screen printing machine 4. When the glass substrate 3 is supported, the conveyor belt 13 will produce a certain degree of deformation.

[0027] Example 3

[0028] like Figure 1 and Figure 6As shown, a workpiece transfer device for a glass screen printing machine includes all the contents of Example 1. In addition, an opening is provided on the bottom surface of the loading box 14, and loading rollers 15 are rotatably installed at the lower ends of both sides of the inner wall of the loading box 14. A notch is provided on one side of the loading roller 15, and one end of the loading roller 15 is fixedly connected to the motor.

[0029] In the above embodiment, it should be noted that the motor is started to drive the loading roller 15 to rotate the side with the notch to the inner wall of the loading box 14 to open the bottom opening of the loading box 14 and allow the glass substrate 3 to fall onto the conveyor belt 13.

[0030] Example 4

[0031] like Figure 1 and Figure 6 As shown, a workpiece transfer device for a glass screen printing machine includes all the contents of Example 1. In addition, a glass wiper 16 is arranged between the glass screen printing machine 4 and the loading box 14. The glass wiper 16 is arranged above the conveyor belt 13. The two ends of the glass wiper 16 are fixedly connected to the loading box 14 through metal brackets.

[0032] In the above embodiment, it should be noted that the glass cleaning strip 16 is a sponge cleaning strip, and the glass cleaning strip 16 can wipe the dust and dirt on the surface of the glass substrate 3 before the glass screen printing machine 4 prints.

[0033] The usage process of the present invention is as follows: a person skilled in the art starts the motor to drive the loading roller 15 to rotate the side with the notch to the inner wall of the loading box 14, and places the glass substrate 3 on the surface of the conveyor belt 13, and starts the motor to drive the transmission roller 11 to drive the conveyor belt 13 to rotate. The glass substrate 3 is transported to the bottom of the glass screen printing machine 4 along the conveyor belt 13. When the glass substrate 3 is transported to the bottom of the glass screen printing machine 4 along the conveyor belt 13, the two sides of the glass substrate 3 will squeeze the contacts 21 and the spring 22, and the pressure sensor detects the pressure signal and sends it to the control terminal 23. After all the pressure sensors detect the pressure signal, the control terminal 23 determines that the glass substrate 3 has completely entered the top of the support plate 20, and then the control terminal 23 controls the hydraulic rod 19 to start to lift the support plate 20. The support plate 20 supports the glass substrate 3 close to the glass screen printing machine 4, and then the glass screen printing machine 4 is started to complete printing. Finally, the control terminal 23 controls the hydraulic rod 19 to lower the support plate 20, and drives the glass substrate 3 to sink away from the glass screen printing machine 4.
