Technical Field
[0001] The utility model relates to the technical field of key elastic force testing equipment, in particular to a key elastic force testing equipment. Background Technique
[0002] Conducting elastic force testing on keys is a very important link in the design and manufacturing process of electronic products. The elastic force of the keys directly affects the realization of their functions. If the elastic force is too small, the keys may not be able to effectively rebound or respond slowly; if the elastic force is too large, it may cause difficulties or fatigue for users to operate, and in some cases, they may not be able to be used. Elastic force testing ensures that the keys work properly within the designed range and meet the functional requirements.
[0003] The original key elastic force testing technology was to manually press with hands and consider the state where the felt elastic force was appropriate as good. There was no data display and it was only judged by human feeling, making it very difficult to establish a standard. This testing method had extremely low efficiency and a high rejection rate, and could not meet the production requirements. Content of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to provide a key elastic force testing equipment.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A key elastic force testing equipment, including a workbench, a frame is fixedly connected to the workbench, a force measuring probe is arranged on the workbench, a robotic arm is rotatably connected to the workbench, a display computer is rotatably connected to the robotic arm, and a fixture tray is arranged on the workbench.
[0006] The effects achieved by the above components are as follows: After starting the device power supply and connecting the serial port cable to be used, the staff places the product to be tested on the fixture tray, and then uses the force measuring probe to test the product to obtain the elastic force value of the product. After the test, data can be saved, and the OK / NG result can be automatically determined. The test results will be displayed on the display computer, which is convenient for the staff to observe, thus avoiding the situation where the original key elastic force testing technology was to manually press with hands and consider the state where the felt elastic force was appropriate as good. There was no data display and it was only judged by human feeling, making it very difficult to establish a standard, resulting in extremely low efficiency and a high rejection rate, and being unable to meet the production requirements.

[0009] Preferably, a first electric slide rail is fixedly connected to the workbench, and the jig tray is slidably connected to the first electric slide rail.
[0010] The effect achieved by the above components is that the drive on the first electric slide rail can be started to drive the jig tray to slide, so as to change the position of the product to be tested on the X-axis and facilitate the testing of different positions of the product.
[0011] Preferably, an operation panel is fixedly connected to the workbench.
[0012] The effect achieved by the above components is that the operation panel can facilitate the staff to change the parameter operations.
[0013] Preferably, two second electric slide rails are fixedly connected to the workbench, and a third electric slide rail is slidably connected to the two second electric slide rails together.
[0014] The effect achieved by the above components is that by starting the drive on the second electric slide rail, the third electric slide rail can be driven to slide up and down to change the position of the force measuring probe on the Z-axis.
[0015] Preferably, a fourth electric slide rail is slidably connected to the third electric slide rail, and the fourth electric slide rail is fixedly connected to the force measuring probe.
[0016] The effect achieved by the above components is that the drive on the third electric slide rail can be started to drive the fourth electric slide rail to move left and right, so as to change the position of the force measuring probe in the Y-axis direction to adapt to products to be tested of different sizes.
[0017] Preferably, two fifth electric slide rails are fixedly connected to the workbench, and a clamping block is slidably connected to the fifth electric slide rail.
[0018] The effect achieved by the above components is that by starting the drives on the two fifth electric slide rails simultaneously, the two clamping blocks can be driven to clamp and limit the product to be tested, making the position of the product more stable.
[0019] Preferably, an electric control box is fixedly connected to the workbench.
[0020] The effect achieved by the above components is that the electric control box supplies power to the whole equipment.
[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows. In the present utility model, by setting a force measuring probe, starting the power supply of the device, connecting the serial port cable to be used, then the staff places the product to be tested on the fixture tray, and then uses the force measuring probe to test the product to obtain the elastic force value of the product.

Without data display, only relying on people's feelings to judge makes it very difficult to make a standard, resulting in extremely low efficiency, high defect rate, and inability to meet production requirements.

A first electric slide rail 4 is fixedly connected to the workbench 1, and the first electric slide rail 4 is slidably connected to the fixture tray 5.

An operation panel 9 is fixedly connected to the workbench 1, and the operation panel 9 can facilitate the staff to change parameter operations. Two second electric slide rails 10 are fixedly connected to the workbench 1, and a third electric slide rail 11 is slidably connected to the two second electric slide rails 10. By starting the drive on the second electric slide rail 10, the third electric slide rail 11 can be driven to slide up and down to change the position of the force measuring probe 3 on the Z-axis. A fourth electric slide rail 12 is slidably connected to the third electric slide rail 11, and the fourth electric slide rail 12 is fixedly connected to the force measuring probe 3.
