Description

Technical Field

[0001] This utility model relates to the technical field of high voltage electrical box testing equipment, and in particular to an integrated automatic conveying and testing device for high voltage electrical boxes. Background Technology

[0002] With the continuous improvement of automation levels in high-voltage electrical equipment, the demand for integrated automatic conveying and testing devices for high-voltage electrical boxes during the production process is increasing. Such devices not only require efficient and continuous conveying capabilities but also the ability to perform online testing of the electrical boxes to improve overall production efficiency and product quality control.

[0003] A search revealed an invention patent with patent number CN 119490043A, entitled "An Electrical Box Testing Device and Method," which includes a conveying unit, multiple blocking units, and a lifting device. This device enables the positioning, conveying, lifting, and transfer of the electrical box under test, as well as its return after testing. However, this solution does not specifically disclose the structural composition of the testing station, nor does it include a positioning and clamping mechanism for high-voltage electrical boxes during testing, thus failing to ensure the stability of the electrical boxes and the accuracy of the test data. Furthermore, the system lacks compatibility design for electrical boxes of different specifications, making it difficult to adapt to the flexible production needs of multi-variety, small-batch production.

[0004] In summary, although existing technologies contain solutions for high-voltage electrical appliance testing wiring structures and basic transmission testing systems, they still have the following shortcomings in practical applications: the lack of precise positioning and clamping structures during the testing process of high-voltage electrical appliances affects testing stability.

[0022] Reference Figures 1 to 4 An integrated automatic conveying and testing device for high-voltage electrical boxes includes a conveying unit 1 and a testing station module unit 2 disposed on the conveying unit 1.

[0023] The conveying unit 1 includes two parallel roller conveyor belts 11 and multiple lifting devices 12. The conveying unit is used to convey the electrical box to be tested.

[0024] The test fixture module 2 is located in the middle of the conveying unit. The test station module 2 includes a test platform 21, which is equipped with multiple quick-plug test interfaces 22 and a clamping and positioning module 23.

[0025] The conveying unit 1 consists of a roller conveyor belt 11 and a transfer plate 13. A liftable transfer plate 13 is provided between the roller conveyor belts 11. The transfer plate 13 is used to place the electrical box to ensure that it can be smoothly transported on the roller conveyor belt 11.

[0026] The lifting device 12 is placed between the roller conveyor belts 11. The lifting device 12 can be a cylinder, a servo drive module, or other drive structure. The transfer plate 13 achieves lifting function through the lifting device 12. When the electrical box moves to the corresponding test station module unit 2 through the conveyor belt, it will automatically rise according to the detection signal and be placed in the gap between the two roller conveyor belts 11. At the same time, the rear conveyor unit 1 stops conveying when the detection is detected. Photoelectric sensors are set in the conveyor unit 1.

[0027] Each set of lifting devices 12 corresponds to a set of measuring station module units 2, ensuring that each set of measuring fixture module units 2 can be used independently. The transfer plate 13 is provided with several sets of limiting blocks 121 for installing electrical boxes. The limiting blocks 121 are also provided with positioning pins 122. After the electrical box is placed in conjunction with the limiting blocks 121, the corresponding position is fixed with the positioning pin, thereby achieving quick installation and fixation.

[0028] The test platform 21 is equipped with multiple quick-plug test interfaces 22. These interfaces can automatically switch the appropriate wiring terminals according to the electrical box model to meet different test requirements. A hydraulic buffer device is installed under the test platform 21. When the electrical box is lifted to the test position, the hydraulic buffer device can absorb the impact force during the lifting process to prevent poor test contact due to vibration.

[0029] The test platform 21 has a clearance groove in the middle to facilitate the ejection of the transfer plate 13 out of the clearance groove, and to cooperate with the clamping and positioning modules 23 around the test platform 21 and the quick-plug test interface 22 for plug-in testing.

[0030] The quick-plug test interface 22 includes a slide rail 221 mounted on the test platform 21, a slider seat 223 mounted on the slide rail 222 via a slider, a test interface 224 mounted on the slider seat 223, and a quick-clamp structure 225 that drives the slider seat 223 to move along the slide rail 222. By adjusting the quick-clamp structure 225, the slider seat 223 is driven to move, thereby driving the test interface 224 to engage with the interface of the electrical box and perform testing. The test interface 224 is externally connected to a test instrument via a wiring harness or electrical signal. The test instrument is used to power on and detect the voltage, resistance, current, etc. of the electrical box.

[0031] The quick-plug test interfaces 22 are respectively set around the test platform 21, and are set according to the position of the electrical box interface and the position of the required structural plug-in.

[0032] The clamping and positioning module 23 includes a mounting base 231 disposed on the test platform 21 and a positioning block 232 disposed on the mounting base 231. The positioning block 232 is used to limit the top height. When the lifting device 12 drives the transfer plate 13 to lift upward, the top of the electrical box contacts the positioning block and stops, which not only limits the height but also has a fixing effect.

[0033] In this implementation, two sets of test station module units 2 are set up, one on the left and one on the right above the conveying unit 1. Each test station module unit 2 is equipped with a lifting device 12 below it. Several sets of transfer plates 13 flow on the conveying unit 1. Corresponding electrical boxes are installed on the transfer plates 13 and fixed in place with the limiting blocks 121 and positioning pins 122 on the transfer plates 13. After installation, the transfer plates 13 with electrical boxes are moved with the conveying unit 1 and stop when they reach the first test station module unit 2. The lifting device 12 is then driven to move the transfer plate 13 with the electrical box installed upward until the electrical box contacts the bottom of the positioning block 232 and stops. The electrical box is pressed and fixed by the positioning block 232. The quick-plug test interfaces 22 around the perimeter are driven to be inserted into the interface of the electrical box for testing.

[0034] The advantages of this utility model are that the integrated clamping and positioning module and the testing station module significantly improve the stability of the high-voltage electrical box during the testing process and ensure the accuracy of the test data. At the same time, the device has good compatibility and can meet the flexible production needs of multiple varieties and small batches, greatly improving the automation level and operating efficiency of the production line, and has high practical value. In addition, the transfer plate is equipped with limit blocks and positioning pins to accommodate different products for installation, so as to realize the installation of different models of products.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
