[0031] like Figure 1-3 As shown, an embodiment of the present invention provides a glass cover plate strength detection device, comprising:

[0032] A test bench 1 having a groove 11 for placing a glass cover plate to be tested, and a pressing assembly 2 for pressing the glass cover plate to be tested movably connected to the test bench 1; wherein the shape of the groove 11 can be adapted to the shape of the glass cover plate to be tested or larger than the size of the glass cover plate to be tested, so that it is located at the center of the test bench 1. At the same time, in order to facilitate personnel to place and take the glass cover plate, the test bench may also have a retrieval slot connected to the groove 11, thereby improving the installation and removal efficiency of personnel, thereby improving the detection efficiency;

[0033] The test assembly 3 includes a mounting plate 31, a first cylinder 32 arranged on the mounting plate 31, a second cylinder 33 arranged at the telescopic end of the first cylinder 32, a pressing rod 34 arranged at the telescopic end of the second cylinder 33 and pointing to and pressing the glass cover to be tested, and a pressure sensor arranged on the pressing rod 34 and used to measure the pressure of the pressing rod 34 pressing the glass cover to be tested; a numerical display screen for displaying and recording data is provided on the surface of the pressure sensor, and the maximum force of the glass cover to be tested can be tested through the provided pressure sensor.

[0034] The glass cover plate strength testing device of the present invention is used by placing the glass cover plate to be tested in the groove 11 of the test table 1, then operating the pressing assembly 2 to press it onto the test table 1, and then starting the first cylinder 32 and the second cylinder 33 to enable the pressing rod 34 provided with a pressure sensor to perform strength testing on the glass cover plate to be tested. The device has a simple structure and is easy to operate.

[0035] Specifically, such as Figure 1-2 As shown, in the embodiment of the present utility model, the pressing assembly 2 includes a fixing frame 21, and the fixing frame 21 is movably connected to a curved arm 23 through a connecting rod 22. One end of the opposite ends of the curved arm 23 is connected to a pressing plate 24, and the other end is connected to the telescopic end of a third cylinder 25. The telescopic end of the third cylinder 25 can drive the curved arm 23 to move upward to press the pressing plate 24 downward to press the glass cover to be tested; wherein, the pressing plate 24 has a pressing groove 242, and the pressing groove 242 cooperates with the groove 11 to improve the pressing effect on the glass cover to be tested.

[0036] During specific use, the telescopic end of the third cylinder 25 is contracted to drive the curved arm 23 to move downward, so that the pressing plate 24 is folded upward, and then the glass cover to be tested is placed in the groove 11. Then, the telescopic end of the third cylinder 25 is driven to extend to drive the curved arm 23 to move upward, so that the pressing plate 24 is folded downward and presses the glass cover to be tested.

[0037] Specifically, such as Figure 3-4 As shown, in the embodiment of the present invention, the pressing plate 24 has a hollow portion 241 so that the glass cover to be tested is partially exposed when pressed by the pressing plate 24, so that the pressing rod 34 can perform strength testing on the glass cover to be tested under the action of the second cylinder 33.

[0038] Specifically, such as Figure 4 As shown, in the embodiment of the present invention, the area of the hollow portion 241 is smaller than the area of the glass cover to be tested, which reduces the overall weight of the pressing plate 24 while ensuring the structural strength. At the same time, it can also prevent the pressing plate 24 from being damaged by excessive pressing force when pressing the glass cover to be tested.

[0039] Based on the above further improvements, in an embodiment of the present invention, the portion of the pressing rod 34 that presses the glass cover to be tested is made of rubber material to reduce damage to the glass cover.

[0040] Based on the above further improvements, such as Figure 4 As shown, in the embodiment of the present invention, a collecting tank 12 is provided in the test bench 1 . The collecting tank 12 is located below the groove 11 and can collect glass debris.

[0041] Based on the above further improvements, such as Figure 3-4 As shown, in an embodiment of the present invention, a collecting assembly 4 is also included, and the collecting assembly 4 includes a collecting box 41 that is slidably connected to the test bench 1 and communicated with the collecting trough 12. A handle 42 is provided on the collecting box 41. The glass fragments generated by the test fall from the collecting trough 12 into the collecting box 41, thereby facilitating regular cleaning by personnel.

[0042] Based on the above further improvements, such as Figure 1-3 As shown, in an embodiment of the present invention, a base plate 5 is further included, on which the test bench 1, the clamping assembly 2 and the test assembly 3 are all arranged, and handles 6 are provided on both sides of the base plate 5. The handles 6 facilitate movement of the device, thereby improving its flexibility.

[0043] In the glass cover plate strength testing device provided by the present invention, the first cylinder 32, the second cylinder 33, and the third cylinder 25 can all be electrically connected to a conventional PLC controller or single-chip microcomputer, enabling the testing device to control the cylinder extension and retraction according to the test results. Of course, the cylinders can also be other conventional cylinder mechanisms, such as electric or hydraulic cylinders, as long as they can achieve linear motion.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
