Description

Technical Field

[0001] This utility model belongs to the field of display glass and relates to an auxiliary device for testing the impact resistance performance of display glass. Background Technology

[0002] Display glass provides physical protection, light transmission, and is the foundation for touch interaction for display panels. Its impact resistance directly affects the durability and safety of display devices during daily use, transportation, or accidental collisions, and is one of the core indicators for measuring display glass quality. Impact resistance testing auxiliary devices are important equipment in the production, research and development, and quality inspection of display glass. Their main function is to accurately and stably quantify the impact resistance of display glass by simulating specific impact conditions (such as the impact of a falling steel ball).

[0003] The device for testing the impact resistance of tempered glass, disclosed in CN211784873U, is simple to install and can be operated with a single button via a magnetic chuck. The magnetic chuck can also be height-adjusted on the upright via a crossbar and sliding sleeve, thereby increasing the versatility of experiments. The aforementioned tempered glass impact resistance testing device has the following drawbacks: it cannot adaptively clamp and fix display glass of different sizes and thicknesses, and when the clamping is not stable, the display glass will shift when the steel ball hits it, thus causing test errors. Utility Model Content

[0004] The technical problem this utility model aims to solve is that it is impossible to adaptively clamp and fix display glass of different sizes and thicknesses. When the clamping is not stable, the display glass will shift when the steel ball impacts it, resulting in test errors. An auxiliary device for testing the impact resistance of display glass includes an impact chassis. A slide rod is fixedly installed on the upper surface of the impact chassis. An electromagnet is slidably installed on the outer surface of the slide rod. A fixing bolt is threaded onto the outer surface of the electromagnet. A steel ball is magnetically attached to the working end of the electromagnet. A clamping unit for adaptively adjusting the clamping of display glass of different specifications is provided on the inner surface of the impact chassis. A steel ball for ensuring the accuracy of the steel ball's fall is provided on the outer surface of the slide rod. A positioning unit is slidably sleeved on the outer surface of the slide rod. The clamping unit includes a base, on the outer surface of which two slides are slidably mounted to perform initial positioning of the display glass. One side surface of each slide is fixedly mounted with an electric push rod, and the working end of the electric push rod is equipped with a pressure plate for pressing the display glass.

[0005] A directional rod is installed in a groove on the outer surface of the platform of the present invention. The directional rod passes through the two slides, and two springs are sleeved on the outer surface of the directional rod.

[0006] In this invention, the two springs respectively abut against the two slides, thereby achieving positioning and clamping of the display glass. The pressing end of the pressure plate is made of rubber.

[0007] The positioning unit of this utility model includes a sliding sleeve, which is slidably mounted on the outer surface of the sliding rod. A fixing bolt is threaded onto the outer surface of the sliding sleeve for adjusting and fixing the sliding sleeve. Two connecting rods are fixedly mounted on the outer surface of the sliding sleeve, and a pipe is installed at the other end of the two connecting rods.

[0008] Both ends of the first pipe of this utility model are threaded with connecting sleeves, and the second pipe is threaded on the inner surface of the connecting sleeve.

[0009] A support rod is fixedly installed on the upper surface of the impact chassis of this utility model, and a controller is installed at one end of the support rod.

[0010] The impact chassis of this invention has a sliding plate mounted on its outer surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention provides a stable guide for the slide table through the directional rod in the clamping unit. Two springs push the slide table to achieve initial positioning and clamping through elastic force. The rubber pressure plate driven by the electric push rod presses and fixes the slide table, ensuring the stability of display glass of different sizes during the testing process.

[0012] This invention, through the channel formed by the combination of pipe one, connecting sleeve and pipe two in the positioning unit, and with the height adjustment function of the sliding sleeve, ensures the stability of the falling path of the steel ball, reduces the interference of air flow on the trajectory of the steel ball, and ensures the accuracy of the impact position.

[0015] like Figures 1 to 5 As shown, an auxiliary device for testing the impact resistance of display glass includes an impact chassis 1. A slide rod 6 is fixedly installed on the upper surface of the impact chassis 1. An electromagnet 7 is slidably installed on the outer surface of the slide rod 6. A fixing bolt 8 is threadedly installed on the outer surface of the electromagnet 7. A steel ball 9 is magnetically attached to the working end of the electromagnet 7. A clamping unit 10 is provided on the inner surface of the impact chassis 1 for adaptive adjustment and clamping of display glass of different specifications. A steel ball 9 is provided on the outer surface of the slide rod 6 for the accuracy of the falling of the steel ball 9. A positioning unit 11 is slidably sleeved on the outer surface of the slide rod 6. The electromagnet 7 is composed of a slide bar seat and an electromagnet, and the electromagnet 7 can be adjusted by sliding on the slide bar 6 through the fixing bolt 8.

[0016] The clamping unit 10 includes a base 101. Two slides 104 are slidably mounted on the outer surface of the base 101 to perform initial positioning of the display glass. Electric push rods 105 are fixedly mounted on one side surface of each slide 104. A pressure plate 106 for pressing the display glass is installed at the working end of the electric push rod 105.

[0017] The base 101 is welded to the inner surface of 1. Rubber pads are glued to the clamping ends of the two slides 104, which can protect the display glass when clamping it. The electric push rod 105 is powered and controlled by the controller 5, which can push the plate 106 to press the display glass tightly against the upper surface of the base 101.

[0018] like Figure 3 As shown, a guide rod 102 is installed in a groove on the outer surface of the base 101. The guide rod 102 passes through two slides 104, and two springs 103 are sleeved on the outer surface of the guide rod 102.

[0019] The guide rod 102 ensures the normal operation of the two springs 103.

[0020] like Figure 3 As shown, two springs 103 abut against two slides 104 respectively, thereby achieving positioning and clamping of the display glass. The pressing end of the pressure plate 106 is made of rubber.

[0021] Two springs 103 abut against two slides 104, so that the two slides 104 are subjected to the same force, thus ensuring that the display glass is always clamped directly below the steel ball 9. The pressing end of the pressure plate 106 is made of rubber, which can protect and prevent slipping when pressing the display glass.

[0022] like Figure 4 and Figure 5 As shown, the positioning unit 11 includes a sliding sleeve 111, which is slidably mounted on the outer surface of the slide rod 6. A fixing bolt 112 is threaded onto the outer surface of the sliding sleeve 111 to adjust and fix the sliding sleeve 111. Two connecting rods 113 are fixedly mounted on the outer surface of the sliding sleeve 111, and a pipe 114 is installed at the other end of the two connecting rods 113.

[0023] By fine-tuning the sliding sleeve 111 using the fixing bolt 2 112, it is possible to... like Figure 4 and Figure 5 As shown, both ends of pipe 114 are threaded with connecting sleeves 115, and pipe 2 116 is threaded on the inner surface of connecting sleeve 115.

[0024] Pipe 114, connecting sleeve 115 and pipe 2 116 can form a channel for the steel ball 9 to fall, and the inner diameter of the channel is 1cm larger than the ball. The upper end of the channel formed by pipe 114, connecting sleeve 115 and pipe 2 116 is 8cm away from the steel ball 9, and the lower end is also 8cm away from the display switch.

[0025] like Figure 4 and Figure 5 As shown, a support rod 4 is fixedly installed on the upper surface of the impact chassis 1, and a controller 5 is installed at one end of the support rod 4.

[0026] The controller 5 can control the solenoid 7 and the electric actuator 105.

[0027] like Figure 4 and Figure 5 As shown, a pull plate 2 is slidably mounted on the outer surface of the impact chassis 1.

[0028] By manually cleaning, the broken display glass can be collected in tray 2 for unified processing.

[0029] Working process or working principle: For the clamping and fixing installation of the display glass, firstly, one of the slides 104 is manually slid towards one end of the base 101 to compress the spring 103. Then, the display glass is placed between the two slides 104. One slide 104 is held by hand, so that the spring 103 rebounds and pushes against the slide 104 to reset and slide. This allows the two slides 104 to position and clamp the display glass. Then, the electric push rods 105 on the two slides 104 are activated to push the pressure plate 106 to press the display glass tightly, thereby fixing the display glass and preventing the steel ball 9 from moving when it hits the display glass and causing any impact. The slide 104 is connected to the second pipe 116 via the connecting sleeve 115 to extend the channel to a suitable length. Then, the second fixing bolt 112 allows the sliding sleeve 111 to slide and adjust on the slide rod 6. The upper end of the channel formed by the combination of the first pipe 114, the connecting sleeve 115, and the second pipe 116 needs to be 8cm away from the steel ball 9, and the lower end needs to be 8cm away from the display lever. This ensures the accuracy of the steel ball 9 when it falls and reduces the influence of external airflow on the deviation.
