Description

Technical Field

[0001] The present invention relates to the technical field of testing devices, and in particular to a keyboard quality testing device and a testing method thereof. Background Art

[0002] A keyboard is a device for inputting instructions and data to operate a computer device. It also refers to a group of function keys that are arranged by a system to operate a machine or device. Keyboards need to be quality tested after they are produced, because keyboards may fall during use or transportation. Therefore, a drop test is needed to test the state of the keyboard after it falls, to see if it is damaged or keys fall off, so as to ensure the production quality of the keyboard. However, existing drop test devices are not convenient to use and cannot test multiple keyboards simultaneously, which increases the workload of staff and reduces the efficiency of the test. In addition, for some poor quality keyboards that fall and produce fragments or keys that fall off, there is a lack of a good limiting mechanism, which causes them to splash randomly and are difficult to collect.

[0014] A testing method comprises the following steps:

[0015] Step 1: Place the keyboard: Place the keyboard on the support driving board;

[0016] Step 2: Move the keyboard upward: start the electric telescopic rod to drive the keyboard upward, and at the same time make the support driving plates move away from each other and no longer support the keyboard, and the clamping driving plates move toward each other to achieve clamping support for the keyboard, and drive the keyboard upward to a specified height;

[0017] Step 3: Drop test of keyboard: As the clamping drive plate moves upward, it moves backward to release the keyboard, and then the keyboard falls into the restraint test set under the action of its own gravity, completing the drop test;

[0021] 1. Multiple groups of support driving plates and clamping driving plates are arranged on the test bearing platform. When performing the drop test, it is placed on the closed support driving plate, and then the electric telescopic rod is started to drive the support driving plate to move upward, which can then drive the keyboard to move upward. During this process, the support driving plates will move backwards and no longer support the keyboard, which is convenient for the later falling of the keyboard.

[0022] 2. As the supporting driving plate and the clamping driving plate move upward, as the supporting driving plate separates, the clamping driving plate will move toward each other, so that the clamping driving plate can clamp the keyboard from both ends. Before the supporting driving plate no longer supports the keyboard, the clamping driving plate has already clamped the keyboard, that is, the clamping driving plate drives the keyboard to a specified height, and then releases the keyboard to achieve free fall, so that the keyboard falls into the restricted test set to complete the drop test. This can achieve synchronous and convenient testing of multiple keyboards, which is very convenient and has high testing efficiency.

[0023] 3. In addition, when the electric telescopic rod is extended upward, as the supporting plate moves upward, it will also drive the movable sealing plate to move, and the movable sealing plate will close the side opening of the limiting test set, so that when the keyboard falls into the limiting test set, it can play a good limiting role for the detached keys and broken fragments to prevent them from splashing at will. When the test is completed, the electric telescopic rod moves downward, driving the movable sealing plate to move away from the limiting test set, thereby opening the side opening of the limiting test set, making it convenient to take out the keyboard while also facilitating the cleaning of the interior.

[0046] A testing method comprises the following steps:

[0047] Step 1: Placing the keyboard: placing the keyboard on the supporting driving plate 3;

[0048] Step 2: Move the keyboard upward: Start the electric telescopic rod 11 to drive the keyboard upward, and at the same time make the support driving plate 3 move away from each other and no longer support the keyboard, and the clamping driving plate 6 moves toward each other to achieve clamping support for the keyboard, and drive the keyboard to move upward to a specified height;

[0049] Step 3: Drop test of keyboard: As the clamping driving plate 6 moves upward, it moves backward to release the keyboard, so that the keyboard falls into the limiting test sleeve 17 under the action of its own gravity, completing the drop test;

[0050] Step 4: Taking out the keyboard: Taking out the keyboard dropped into the restriction test set 17;

Before the keyboard is separated from the supporting driving plate 3, the clamping driving plate 6 has already clamped the keyboard, that is, after the keyboard is separated from the supporting driving plate 3, the clamping driving plate 6 drives the keyboard to a specified height. When it reaches the specified height, The mating connecting rod 42 also enters the release and pull-back channel 185, and then drives the movable connecting bar 4 to move in the opposite direction under the action of the release and pull-back channel 185, so that the clamping driving plate 6 can be driven to move in the opposite direction to release the keyboard, so that the keyboard falls into the restricted test sleeve 17 under the action of its own gravity to complete the drop test. In addition, when the electric telescopic rod 11 drives the mating bearing plate 12 to move upward, the connecting gear 7 will be driven to rotate under the action of the connecting rack 162, and then the movable sealing plate 8 will be driven to move in the direction of the restricted test sleeve 17 under the action of the thread, so that the restricted test The side opening of the test sleeve 17 is in a closed state, so when the keyboard falls into the limiting test sleeve 17, it can limit the generated fragments and detached keys to prevent them from splashing randomly, and then start the electric telescopic rod 11 to drive the matching carrier plate 12 to move downward for reset, and at the same time, the movable sealing plate 8 moves away from the limiting test sleeve 17, so that the side opening of the limiting test sleeve 17 can be in an open state, which is convenient for taking out the keyboard and also convenient for cleaning the fragments and detached keys inside it, and can realize synchronous testing of multiple keyboards, which is very convenient and has high testing efficiency.
