[0023] The positioning device of this photovoltaic glass edging machine includes a roller conveyor 1, a belt conveyor 2, a primary positioning assembly 4, and a secondary positioning assembly 3 (see the attached instruction manual). Figure 1 and 2 ).

[0024] A belt conveyor 2 is installed at one end of the roller conveyor 1. Both roller conveyor 1 and belt conveyor 2 are purchased equipment. Currently, roller conveyors and belt conveyors available on the market that can meet the transportation requirements of photovoltaic glass can meet the needs of this application.

[0025] Two sets of secondary positioning components 3 are symmetrically installed at the upper end of the belt conveyor 2 (see the instruction manual). Figure 1 and 2 The secondary positioning component 3 includes a longitudinal slide plate 11, a push cylinder 10, an assembly box 12, and a guide roller 14.

[0026] The upper end of the belt conveyor 2 is equipped with a longitudinal slide plate 11 via a pusher cylinder 10; one end of the longitudinal slide plate 11 is equipped with an assembly box 12 with a long strip structure in the shape of a "C"; multiple guide rollers 14 are installed inside the assembly box 12 via a drive shaft 13.

[0027] During operation, the push cylinder 10 drives the assembly box 12 and guide roller 14 to approach the photovoltaic glass via the longitudinal slide plate 11, thus achieving the purpose of positioning it.

[0028] The assembly box 12 and the longitudinal slide plate 11 are connected to each other by a plurality of inclined spring plates 15. The purpose of setting the spring plates 15 is to enable the assembly box 12 to push the spring plates 15 to move backward against the elastic force when the guide rollers 14 come into contact with the photovoltaic glass, thereby avoiding the problem of glass crushing due to hard contact between the guide rollers 14 and the guide rollers 14.

[0029] The secondary positioning assembly 3 also includes a drive sprocket 16, a drive chain 17, a drive sprocket 19, and a control motor 18; the drive shaft 13 inside the guide roller 14 extends to the upper end of the assembly box 12; adjacent drive shafts 13 are interconnected via the drive sprocket 16 and the drive chain 17; the drive sprocket 19 is mounted on the assembly box 12 via the control motor 18; the drive sprocket 19 is connected to the adjacent drive shaft 13 via the drive chain 17 (see the appendix to the instruction manual). Figure 3 ).

[0030] The purpose of this secondary positioning component 3 is to enable the control motor 18 to drive the guide roller 14 to rotate via the transmission sprocket 16, transmission chain 17, drive sprocket 19, and transmission shaft 13 during operation. The surface linear velocity of the guide roller 14 during rotation is consistent with the running speed of the belt conveyor 2, thus solving the problems of easy damage to the glass and low positioning accuracy in existing positioning devices.

[0031] A primary positioning assembly 4 is installed at one end of the roller conveyor 1 (see the instruction manual appendix). Figure 1 and 2 The primary positioning assembly 4 includes a base 5, a sliding seat 6, a drive screw 8, and a guide roller shaft 9 (see the instruction manual appendix). Figure 6 ).

[0032] Two sets of sliding seats 6 are symmetrically mounted on the base 5 via guide rails; a drive screw 8 is mounted in the middle of the base 5 via a drive motor 7; the drive screw 8 is connected to the corresponding sliding seat 6 via a screw nut; when the drive screw 8 rotates forward, the sliding seats 6 move closer together; when the drive screw 8 rotates in the reverse direction, the sliding seats 6 separate; multiple guide roller shafts 9 are spaced apart at the top of the sliding seats 6; the guide roller shafts 9 pass through the roller conveyor 1 and extend to its upper end. The purpose of this primary positioning assembly 4 is to ensure that during operation, when the roller conveyor 1 transports photovoltaic glass, the guide roller shafts 9 can move closer together, pushing the photovoltaic glass to the middle position of the roller conveyor 1, thus achieving the purpose of adjusting the posture of the photovoltaic glass.

[0033] A plastic anti-wear layer is provided on the surface of the guide roller shaft 9. The plastic anti-wear layer has a certain degree of flexibility to prevent the guide roller shaft 9 from cracking the photovoltaic glass.

[0034] The positioning device of this photovoltaic glass edging machine operates as follows: First, the roller conveyor 1 moves the photovoltaic glass towards the belt conveyor 2. During this process, when the photovoltaic glass moves between the guide roller shafts 9, the drive motor 7 drives the drive screw 8 to rotate forward, causing the sliding seat 6 and the guide roller shafts 9 to move closer together. As the guide roller shafts 9 move closer together, they push the photovoltaic glass to the middle position of the roller conveyor 1, thus achieving the purpose of adjusting the posture of the photovoltaic glass.

[0035] After the guide roller shaft 9 pushes the photovoltaic glass to the middle position of the roller conveyor 1, the drive motor 7 will drive the drive screw 8 to rotate in the opposite direction, so that the sliding seat 6 and the guide roller shaft 9 are reset.

[0036] After the above steps are completed, when the roller conveyor 1 pushes the photovoltaic glass onto the belt conveyor 2, during the backward transport of the photovoltaic glass by the belt conveyor 2, the pushing cylinder 10 drives the assembly box 12 and guide roller 14 to approach and contact the photovoltaic glass via the longitudinal slide plate 11, pushing the photovoltaic glass to the designated processing position. During this process, the control motor 18 drives the guide roller 14 to rotate via the transmission sprocket 16, transmission chain 17, drive sprocket 19, and transmission shaft 13. The surface linear velocity of the guide roller 14 during rotation is consistent with the running speed of the belt conveyor 2, thus avoiding the problem of the guide roller 14 obstructing the operation of the photovoltaic glass. In this way, the guide roller 14 completes the secondary positioning work. At this point, the positioning device of the photovoltaic glass edging machine has completed the positioning work of the photovoltaic glass. Subsequently, the guide roller 14 resets, and the positioning device of the photovoltaic glass edging machine can enter the next working cycle.

[0037] The positioning device of this photovoltaic glass edging machine has a compact structure and ingenious design. It can position the photovoltaic glass through two positioning methods. During operation, the surface linear speed of the guide roller 14 is consistent with the running speed of the belt conveyor 2. This solves the problems of easy damage to the glass and low positioning accuracy of existing positioning devices, making it particularly suitable for the needs of photovoltaic glass edging machines.
