Technical Field

[0001] The utility model belongs to the technical field of display screen production, and particularly relates to a strength testing device for display screen production. Background Art

[0002] A display screen, also known as a monitor, is a display tool that displays certain electronic files on the screen through a specific transmission device. During the production and processing of the display screen, the pressure strength of the display screen is generally tested to ensure that the display screen meets the production standards.

[0003] For example, a strength testing device for display screen production with publication number "CN116907994B" includes a testing machine body, a feeding mechanism installed on the testing machine body, a clamping mechanism installed on the feeding mechanism, a locking mechanism installed on the feeding mechanism, a resistance mechanism installed on the feeding mechanism, a protective mechanism installed on the testing machine body, and a driving mechanism installed on the feeding mechanism; the feeding mechanism and the clamping mechanism cooperate to facilitate clamping and placing the display screen to be tested, and push it into the testing machine body for loading, which is convenient and safe to operate; the feeding mechanism drives and controls the locking mechanism so that the locking mechanism locks the clamping mechanism stably; the feeding mechanism drives the resistance mechanism so that the resistance mechanism resists and unloads the placed display screen; the feeding mechanism drives the driving mechanism to work so that the protective mechanism is controlled, which is beneficial for protection during testing, and the protective mechanism is opened after the test to facilitate unloading.

[0004] The inventor believes that the above-mentioned strength testing device can be used to perform strength testing operations on display screens during production. However, when the strength testing device is in use, since there is no heat dissipation mechanism on the base shell of the test host, when the components installed inside the base shell of the test host are in operation, the heat generated will accumulate inside the shell, causing the temperature inside the shell to rise. When the components inside the shell operate in such an environment, they are prone to accelerated aging, thereby affecting the service life of the components and bringing inconvenience to the use of the strength testing device.

[0005] Therefore, the present invention provides a strength testing device for display screen production to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a strength testing device for display screen production, aiming to solve the problem proposed in the prior art that the base shell of the test host is not provided with a heat dissipation mechanism, and the heat generated by the components installed inside the shell during operation will be accumulated inside the shell. When the components operate in such an environment, they are prone to accelerated aging, thereby affecting the service life of the components.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a strength testing device for display screen production, comprising a test host, wherein an air inlet is provided on one side surface of the bottom end of the test host, and an exhaust port is provided on the other side surface of the bottom end of the test host, a first protrusion is connected to the one side surface of the test host outside the air inlet, a placement groove is provided on the front end surface of the first protrusion, a dustproof net is connected on the inner surface of the placement groove, a plug hole is provided on the top surface of the dustproof net, one end of the insertion rod is connected on the inner surface of the plug hole, the other end of the insertion rod passes through a vertical block connected to the top surface of the first protrusion, a movable groove is provided inside the vertical block, a spring passed through the insertion rod is connected on the inner surface of the movable groove, a pull block is connected on the top surface of the insertion rod, a second protrusion is connected to the one side surface of the test host outside the exhaust port, an exhaust fan is connected on the inner surface of the second protrusion, and a shielding mechanism is also provided on the one side surface of the test host at both ends of the second protrusion.

[0008] In order to cover the opening at one end of the second protrusion, as a preferred strength testing device for display screen production of the present invention, the covering mechanism includes: an electric push rod, a baffle, a sealing block and a slot. The electric push rod is connected to the surface of one side of the test host at both ends of the second protrusion, the movable end surface of the electric push rod is connected to the baffle, and the one side surface of the baffle is connected to the sealing block. One end of the sealing block extends into the slot opened on the surface of one side of the second protrusion.

[0009] In order to realize the disassembly and assembly of the dustproof net, as a preferred strength testing device for display screen production of the present invention, the dustproof net is slidably connected to the first protrusion through the placement groove, and the insertion rod is slidably connected to the dustproof net through the insertion hole.

[0010] In order to realize the movement of the insertion rod, as a preferred strength testing device for display screen production of the present invention, the insertion rod is preferably connected to the vertical block through a sliding connection, and the insertion rod forms an elastic structure with the vertical block through a movable groove and a spring.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model cooperates with the air inlet, the exhaust port, the first protrusion, the dustproof net, the second protrusion and the exhaust fan. When the exhaust fan is started, the air inside the test host base shell can be discharged through the exhaust port, so that the external air will enter the shell through the air inlet after being filtered by the dustproof net, so that the air inside the base shell is in a fast circulation flow state, and the heat generated by the internal components of the base shell during operation can be quickly evacuated, thereby ensuring the stability of the temperature inside the shell and preventing the internal temperature of the shell from being too high and accelerating the aging of the components.

[0027] During specific use, the movable end of the electric push rod 15 can drive the baffle 16 to move, so that the surface of one side of the baffle 16 contacts the second protrusion 13. At this time, the sealing block 17 on the baffle 16 will also move to the card groove 18, allowing the sealing block 17 to be elastically engaged in the card groove 18, thereby increasing the sealing between the baffle 16 and the second protrusion 13, so that the baffle 16 can cover and protect the opening at one end of the second protrusion 13.

[0028] Preferably, the dust-proof net 6 is slidably connected to the first protrusion 4 through the placement groove 5 , and the insertion rod 8 is slidably connected to the dust-proof net 6 through the insertion hole 7 .

At this time, the exhaust fan 14 will evacuate the air inside the base shell of the test host 1 to the outside through the exhaust port 3, and the external air will enter the base shell of the test host 1 from the air inlet 2. At the same time, the dustproof net 6 provided at the air inlet 2 can filter the incoming air to avoid Dust follows the air into the interior of the shell, so that the air inside the base shell of the test host 1 is in a fast circulation flow device, so that the heat generated by the components inside the shell during operation can be quickly evacuated, ensuring the stability of the temperature inside the shell and avoiding excessive temperature inside the shell that accelerates the aging of components. When the test host 1 is used up, the exhaust fan 14 will stop running. At this time, the PLC control switch will start the electric push rod 15 again, so that the movable end of the electric push rod 15 drives the baffle 16 to move, so that the surface of one side of the baffle 16 contacts the second protrusion 13.
