Description

Technical Field

[0001] The utility model relates to the technical field of display screen production, in particular to a product dropping alarm device. Background Art

[0002] In order to improve the bonding effect, during the production of touch display screens, vacuum bonding is adopted. Usually, upper and lower platens are provided on the vacuum bonding device. The components to be bonded are placed on the lower platen, and a vacuum pump chamber is provided above the upper platen. During bonding, the platen is covered by the vacuum pump chamber, and the air in the chamber is pumped out, thereby reducing bonding bubbles and improving the bonding quality. However, during the process of evacuating the upper platen cavity, the vacuum adsorption of the product is turned off, and the lower platen only relies on the auxiliary adsorption rubber ring to adsorb the product. However, the adsorption rubber ring is unstable during use, which may cause the product to drop. The dropping of the product will cause the product to shift, which will make the equipment unstable and difficult to monitor and detect, resulting in the risk of product leakage.

[0021] A product drop alarm device, refer to Figure 1 The laminating jig 10 is composed of a laminating jig 10, which holds the product to be laminated. Since the laminating jig 10 forms a sealed cavity after being molded with the upper platen, the sealed cavity needs to be evacuated to apply parallel force to the product to complete the laminating and laminating process. During the vacuuming process, the vacuum that holds the product is turned off, and only the auxiliary adsorption rubber ring is used to hold the product. However, the adsorption rubber ring is unstable during use and can cause the product to fall off. Therefore, the laminating jig 10 is provided with a sensor to detect whether the product has fallen off.

[0022] Further, refer to Figure 1 The product is a cover plate 20 and a display screen 30 arranged in sequence from top to bottom. The display screen 30 is placed on the bonding fixture 10, and the cover plate 20 and the display screen 30 are bonded and fixed by a vacuum bonding setting.

[0023] Reference Figure 1 and Figure 2 The sensing element is a sensor 40, which is used to emit a sensing light to detect whether the product has fallen off. The sensor 40 is fixed to the side of the laminating jig 10. The sensor 40 senses whether the product has fallen off from the side of the laminating jig 10, and the sensitivity of the sensing is higher.

[0024] Further, refer to Figure 1 and Figure 2 A fixing block 50 is provided on the side of the laminating jig 10 , and the sensor 40 is fixed on the fixing block 50 , and the sensing direction of the sensor 40 is toward the side of the product.

[0025] Further, refer to Figure 1 and Figure 2 The sensing light of sensor 40 is 1mm above the upper surface of the product, that is, the sensing light of sensor 40 is 1mm above the upper surface of cover 20. The sensing light of sensor 40 is directed upwards to the product. During the bonding process, if the sensing light of sensor 40 can sense the product, it indicates normal bonding. If the sensing light of sensor 40 cannot sense the product, it means that the product is at risk of falling off.

[0026] Further, refer to Figure 1 An alarm 60 is also provided on the side of the laminating jig 10. The alarm 60 is used to sound an alarm when the sensor 40 does not sense the product to remind the operator.

[0027] Further, refer to Figure 1, a controller 70 is also provided on the side of the laminating jig 10. The controller 70 is electrically connected to the sensor 40 and the alarm 60. When the sensor 40 does not sense the product, it indicates that there is a risk of the product falling off. To control the alarm 60 to give an alarm, so that the operator can check the adsorption rubber ring of the equipment, maintain the stability of the equipment, and at the same time isolate the fallen-off product to prevent leakage.

The cover plate 20 is located above the display screen 30, and the cover plate 20 is placed on the upper end surface of the laminating jig 10. An FPC 31 is bonded to the display screen 30, and an avoidance groove 12 is formed at the position of the laminating jig 10 relative to the FPC 31. After the display screen 30 is received in the receiving groove 11, the FPC 31 is correspondingly placed in the avoidance groove 12.

[0029] Further, referring to Figure 3 , the laminating jig 10 is fixed on the vacuum laminating equipment. Threaded holes 13 for fixing on the vacuum laminating equipment are formed on the laminating jig 10. The threaded holes 13 penetrate through the upper and lower surfaces of the laminating jig 10, and the threaded holes 13 are located in the receiving groove 11. There are multiple threaded holes 13, and the multiple threaded holes 13 are respectively located at the four corners of the laminating jig 10.
