[0002] After the automotive glass is screen printed, a positioning jig is required to fix it to check the printing quality of the glass.

[0003] The patent with the application number 201620473204.1 discloses a glass screen printing detection platform, which includes a plurality of rollers arranged at intervals for conveying glass, and a support structure for lifting the glass from the rollers; the support structure includes at least one cylinder installed under the rollers, a cross bar connected to the piston rod of the cylinder, a plurality of support rods fixed to the cross bar at intervals, and universal wheels connected to the ends of the support rods, and each support rod is located between two adjacent rollers.

[0004] After the above technical solution uses multiple cylinders to drive the cross bar and the support rods to lift the glass from between multiple rollers, the universal wheels at the top of the support rods are used to detect the glass screen printing. However, it is difficult to ensure complete horizontality during the rising process of the glass. Therefore, when the glass is only supported by the universal wheels, it is easy to fall, and the stability of the glass screen printing detection is poor. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a positioning jig for automatic glass screen printing detection for the deficiencies of the prior art. Through the cooperation of the first electric push rod and the moving plate structure with the spring structure in the rubber fastening plate and the fixed tube, the function of positioning the glass printing wire detection is realized, and the problem of poor stability of the glass screen printing detection is solved.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A positioning jig for automatic glass screen printing detection, including a mounting frame and a glass main body embedded in the mounting frame. A plurality of conveying rollers for supporting the glass main body are equidistantly arranged in the mounting frame, and a lifting mechanism is installed at the bottom end of the mounting frame. First electric push rods are fixed on both sides of the outer wall of the mounting frame. Moving plates are slidably installed at both ends of the plurality of conveying rollers. A fixed tube is installed on the outer wall of the moving plate. The moving end of the electric push rod is slidably inserted into the fixed tube, and a spring abutting against the moving plate is installed in the fixed tube.

[0007] Further, bearings are installed at both ends of the conveying rollers, and the plurality of conveying rollers are rotatably inserted into the mounting frame through the bearings.

[0008] Further, rubber fastening plates are installed on one side surfaces of the two moving plates facing each other, and arc-shaped grooves are formed in the inner walls of the rubber fastening plates.

[0009] Furthermore, a telescopic groove is formed in the side wall of the fixed pipe, and the spring is embedded in the telescopic groove.

[0010] Furthermore, an anti - detachment part is fixedly installed at the moving end of the first electric push rod, and the anti - detachment part abuts against the inner wall of the telescopic groove.

[0011] Furthermore, the lifting mechanism includes a second electric push rod fixed to the bottom end of the mounting frame and a lifting frame connected to the second electric push rod, and the lifting frame is embedded in the mounting frame.

[0012] Furthermore, the lifting frame is of a U - shaped structure, and supporting plates staggered with the conveying rollers are fixed on both sides of the top end surface of the lifting frame.

[0013] Furthermore, through holes are formed on both sides of the bottom wall of the mounting frame, and positioning rods that fit and insert into the through holes are fixed to the bottom end of the lifting frame.

[0014] The beneficial effects of the present utility model are as follows:

[0015] (1) In the present utility model, a lifting frame is provided at the bottom end of the mounting frame. After the second electric push rod is started, it drives the lifting frame and the supporting plates to move upward, and during the movement, the two supporting plates push the glass body away from the conveying rollers. The two supporting plates rising synchronously prevent the glass body from tilting during the movement, improving the stability of the glass body during the lifting process.

[0016] (2) In the present utility model, moving plates are slidably sleeved at both ends of multiple supporting rollers. After the glass body rises, the first electric push rod drives the anti - detachment part to slide in the telescopic groove, and during the sliding process, the spring is compressed. The spring then pushes the moving plate to slide on the supporting roller, causing the rubber fastening plate on the side wall of the supporting roller to abut against the side wall of the glass body through the arc - shaped groove. As the first electric push rod continues to move and compresses the spring to deform, the extrusion force between the rubber fastening plate and the side wall of the glass body is increased. The spring is used to adjust the extrusion force for positioning the detection of the glass body, avoiding the situation that the glass body is damaged due to excessive extrusion force during positioning.

[0024] Embodiment 1

[0025] As Figure 1 and Figure 4 shown, this embodiment provides a positioning jig for automatic glass screen printing detection, including a mounting bracket 1 and a glass body 4 embedded in the mounting bracket 1. A plurality of conveying rollers 6 for supporting the glass body 4 are equidistantly arranged in the mounting bracket 1, and a lifting mechanism is installed at the bottom end of the mounting bracket 1. Among them, first electric push rods 2 are fixed on both sides of the outer wall of the mounting bracket 1. Moving plates 3 are slidably installed at both ends of the plurality of conveying rollers 6. A fixed tube 15 is installed on the outer wall of the moving plate 3. The moving end of the electric push rod is slidably inserted into the fixed tube 15, and a spring 12 abutted against the moving plate 3 is installed in the fixed tube 15.

[0026] The lifting mechanism includes a second electric push rod 8 fixed to the bottom end of the mounting frame 1 and a lifting frame 9 connected to the second electric push rod 8. The lifting frame 9 is embedded in the mounting frame 1. The lifting frame 9 is in a U-shaped structure, and support plates 11 staggered with the conveying rollers 6 are fixed on both sides of the top end surface of the lifting frame 9. Through holes 16 are formed on both sides of the bottom wall of the mounting frame 1. A positioning rod 7 that fits and inserts into the through holes 16 is fixed to the bottom end of the lifting frame 9. After the second electric push rod 8 is started, it drives the lifting frame 9 and the support plates 11 to move upward, and during the movement, the two support plates 11 push the glass body 4 to separate from the conveying rollers 6. The two support plates 11 rising synchronously prevent the glass body 4 from tilting during the movement, improving the stability of the glass body 4 during the lifting process.

[0027] Embodiment 2

[0028] As Figure 2 and Figure 3 shown, the same or corresponding components as those in Embodiment 1 adopt the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this Embodiment 2 and Embodiment 1 is that bearings are installed at both ends of the conveying rollers 6, and multiple conveying rollers 6 are rotationally inserted into the mounting frame 1 through the bearings. Rubber fastening plates 5 are installed on the opposite side surfaces of the two moving plates 3. An arc-shaped groove 10 is formed on the inner wall of the rubber fastening plate 5. A telescopic groove 13 is formed on the side wall of the fixed pipe 15. A spring 12 is embedded in the telescopic groove 13. An anti-disengagement portion 14 is fixedly installed at the moving end of the first electric push rod 2. The anti-disengagement portion 14 abuts against the inner wall of the telescopic groove 13. After the glass body rises, the first electric push rod 2 drives the anti-disengagement portion 14 to slide in the telescopic groove 13, and during the sliding process, the spring 12 is compressed, causing the spring 12 to push the moving plate 3 to slide on the support roller, so that the rubber fastening plate 5 on the side wall of the support roller abuts against the side wall of the glass body 4 through the arc-shaped groove 10. As the first electric push rod 2 continuously moves and compresses the spring 12 to deform, the pressing force between the rubber fastening plate 5 and the side wall of the glass body 4 is increased.

[0029] Working steps

[0030] Step 1: During use, the glass body 4 is conveyed on top of multiple moving rollers. After the second electric push rod 8 is started, it drives the lifting frame 9 and the pallet 11 to move upward, and during the movement, the two pallets 11 push the glass body 4 to separate from the conveying roller 6. The two pallets 11 rising synchronously prevent the glass body 4 from tilting during movement. After the glass body 4 rises, the first electric push rod 2 drives the anti-detachment part 14 to slide in the telescopic groove 13, and during the sliding process, it squeezes the spring 12, causing the spring 12 to push the moving plate 3 to slide on the support roller, so that the rubber fastening plate 5 on the side wall of the support roller abuts against the side wall of the glass body 4 through the arc-shaped groove 10. As the first electric push rod 2 continues to move and squeezes the spring 12 to deform, the extrusion force between the rubber fastening plate 5 and the side wall of the glass body 4 is increased, and the extrusion force of the spring 12 is adjusted to position the detection of the glass body 4.

[0031] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
