Description

LCM module vibration testing device

Technical Field

The utility model belongs to the technical field of liquid crystal display devices, and particularly relates to a vibration testing device for LCM (liquid crystal module).

Background

The LCM module is a module for assembling parts such as a liquid crystal display device, a connector, a peripheral circuit for control and driving, a PCB, a backlight, and a structural member. The LCM module is used as an assembly main body of the liquid crystal display, strict damage test is required before standardized production and delivery, and in order to standardize and reference the result parameters of the test, the LCM module needs to be tested by a professional testing machine, and the vibration test can test the strength and stability of the LCM module in shaking of various frequencies. When vibration test is performed, the LCM module is needed to be held by a special fixture, then the fixture and the LCM module are fixed on a test mechanism, and vibration test is performed.

In carrying out the utility model, the inventors have found that the prior art has at least the following problems:

when testing the LCM module, vibration test is required to be carried out in the horizontal direction and the vertical direction, so two clamps are required to clamp corresponding to one LCM module. In order to improve the reliability of the test result, the connection between the clamp and the test machine is very firm, the disassembly and assembly are very troublesome, and the work efficiency is greatly reduced due to frequent disassembly and assembly. The existing LCM module vibration test fixture is not universal, and a new fixture needs to be designed for testing one LCM module plate, so that manpower and material resources are consumed. When the damage test is carried out, the clamp is also subjected to severe conditions, and if the clamp is damaged, the clamp needs to be replaced integrally, so that the clamp is quite low in cost and consumes money. Related patents are searched, and similar patents are not found.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, an LCM module vibration testing apparatus has:

a fixed bottom plate; m10 locating holes with the interval of 100mm are formed in the edge of the fixed bottom plate, and can be matched and connected with vibration equipment.

The fixed bracket is arranged on the fixed base; the movable bracket is slidably arranged on the fixed bottom plate; the fixed bracket and the movable bracket are L-shaped angle irons. The fixed angle steel is made of aluminum alloy and used for connecting the fixed sieve plate and the fixed bottom plate and ensuring the perpendicularity of the vertical fixed sieve plate.

The first fixed screen plate is fixedly arranged on the fixed bracket; the second fixed screen plate is fixedly arranged on the fixed bottom plate; the fixed sieve plate is spliced with the side surface through the bottom surface, and in the space of 180mm multiplied by 180mm, a placing groove with the groove width of 3mm is processed, and each groove is separated by 8mm.

The adjusting angle steel is connected with the adjusting sieve plate and the fixing bottom plate, the adjusting angle steel is connected with the fixing bottom plate through the sliding block nut, the adjusting sieve plate can be manually adjusted, and the sieve plate can be fixed in two vertical positions of high and low.

the locking device is arranged on the movable support, the locking device is a locking nut, and the position of the movable support on the guide rail is locked through the locking nut.

During the use, put into the fixed sieve earlier, confirm the fixed sieve in the ascending location of vertical direction again, later through adjusting the angle steel with the LCM module spacing in the position of adjusting in the track, as shown in FIG. 2.

And positioning grooves matched with the workpieces are formed in the first fixed screen plate, the second fixed screen plate and the movable screen plate. The screen plate is provided with placing grooves with the groove width of 3mm, and the grooves are separated by 8mm.

The guide rail is arranged on the fixed bottom plate, and the sliding block matched with the guide rail is arranged at the bottom of the movable support to play a role in guiding.

The first fixed sieve plate is fixedly arranged on the fixed support through bolts, and is convenient to assemble and disassemble.

The adjusting sieve plate has high and low positioning in the positioning of the adjusting angle steel, because the vibration test needs to be performed up and down, if the universal long plate is designed, the test condition can not be observed, and the problem of displacement deviation caused by vibration in the vertical direction can be effectively solved by hole positioning;

in the testing process, a certain allowance is required to be reserved according to requirements, and the adjusting sieve plate is adjusted through the sliding block nut, so that the testing machine is more convenient.

The clamp is positioned through the sliding block nut and the screw hole, and can be adjusted and limited in an electrodeless manner under the condition of not disassembling and assembling the bottom plate. All structural designs related to limit clamping by the principle are in the protection scope.
