[0002] In the touch screen production process, there is a step to use a UV curing machine to cure the glue layer between the touch screen functional sheet and the panel. The product to be cured is placed on a conveying device, conveyed by the conveying device under the UV lamp, and cured by irradiation with the UV lamp.

[0003] At present, the UV light generated by the UV curing machine has an attenuation area of ​​about 50mm on both sides of the conveyor in the width direction, so the products placed on both sides of the conveyor cannot be completely cured.

After curing, the conveying device 4 continues to convey it to the back of the lampshade 2.

[0015] The boundary indicating device includes two lasers 1, which are arranged at a certain distance along the width direction w of the conveying device and are respectively fixed on the lampshade 2 of the UV curing machine. The visible light line 200 projected by the laser 1 on the conveying device 4 is located in front of the lampshade 2 and parallel to the product conveying direction i. In other embodiments of the utility model, the two lasers 1 can also be arranged on the same slide rail / rod, and the slide rail / rod is fixed on the lampshade 2.

[0016] Figure 2 is a schematic diagram of the structure of the laser 1, see Figure 2 The laser 1 includes a laser head 11, an angle adjustment mechanism 12 and a connection mechanism 13. The laser head 11 is connected to the connection mechanism 13 via the angle adjustment mechanism 12. The laser head 11 is used to emit a linear visible light laser to the conveying device 4 to form a visible light line 200 on the conveying device 4. In other embodiments of the utility model, the laser 1 may also have other structures, for example, the angle adjustment mechanism 12 may not be included.

[0017] The angle adjustment mechanism 12 includes an upper connecting member 121, a lower connecting member 122, an upper locking member 123, a lower locking member 124 and two clips 125. The upper end of the upper connecting member 121 is fixedly connected to the laser head 11, the lower end of the upper connecting member 121 is a ball head, the lower end of the lower connecting member 122 is fixedly connected to the connecting mechanism 13, the upper end of the lower connecting member 122 is a ball head, the ball head of the upper connecting member 121 is clamped between the upper parts of the two clips 125, and the ball head of the lower connecting member 122 is fixedly connected to the connecting mechanism 13. The upper locking member 123 and the lower locking member 124 are sandwiched between the lower parts of the two clamping pieces 125, and are disposed between the upper connecting piece 121 and the lower connecting piece 122, and are disposed close to the upper connecting piece 121 and the lower connecting piece 122, respectively. The upper locking member 123 and the lower locking member 124 are used to clamp the ball heads of the upper connecting piece 121 and the lower connecting piece 122 by the two clamping pieces 125, and the left-right and pitch rotation adjustment of the laser head 11 can be realized simultaneously by rotating the upper connecting piece 121 and / or the lower connecting piece 122.

[0019] Prior to the present invention, lines were generally drawn on the conveyor belt, and the lines 100 on both sides were used to distinguish the areas where the product can be completely cured and the areas where it cannot be completely cured. However, the lines 100 are easily worn away, and it is not easy to be found when the product has a small amount of pressure line. The present invention uses a linear visible light laser emitted by a laser 1 to hit the conveyor device 4, forming a visible light line 200 on the conveyor device 4 to replace the line 100. Compared with the line 100, the visible light line 200 is brighter and clearer and will not be worn away. When the product exceeds the area where it can be completely cured, it is also easy to be found because the visible light line 200 is projected on the product.

[0020] To facilitate the installation and debugging of the laser 1, it is not necessary to remove the lines 100 on the conveyor belt first, or if there are no lines 100 on the conveyor belt, draw lines 100 on the conveyor belt first. When installing and debugging the laser 1, use the lines 100 as a reference to adjust the installation position of the laser 1 and the orientation of the laser head 11 so that the visible light lines 200 are aligned with the lines 100.
