[0022] Reference Figures 1 to 5 This utility model discloses a PCBA testing device, including: a first housing 100, a second housing 200, a tester 300, a housing cover 400, and a cylinder 500.

[0023] The first housing 100 is mounted on the control panel, and the second housing 200 is hinged to the first housing 100. The second housing 200 is positioned above the first housing 100. The first housing 100 serves as the base support, and the external circuit of the tester 300 is installed inside the first housing 100.

[0024] The tester 300 is disposed within the second housing 200. The tester 300 includes a first test board 310 and a second test board 320. The first test board 310 is disposed at the bottom of the second housing 200, and the second test board 320 is disposed above the first test board 310. The first test board 310 has an installation space 311, and an auxiliary structure 311a is disposed within the installation space 311. The installation space 311 is used to install the PCBA board to be tested, and the auxiliary structure 311a is used to assist in placing the PCBA board into the installation space 311 and removing the PCBA board from the installation space 311. The second test board 320 is equipped with test elements and is used to cooperate with the first test board 310 to fix and test the PCBA board under test. The first test board 310 is set in the mounting space 311, which is used to install the PCBA board. The mounting space 311 is equipped with a component placement and removal auxiliary structure 311a. The component placement and removal auxiliary structure 311a makes it easier for the operator to hold the PCBA board and place it into the mounting space 311 and remove the PCBA board from the mounting space 311, thereby improving testing efficiency and avoiding damage to the PCBA board due to inaccurate holding position.

[0025] The cover 400 is hinged to the second enclosure 200. The cover 400 is used to cover the internal space of the second enclosure 200 and to close the second enclosure 200, thereby reducing the influence of external factors on the test results during the testing of the PCBA board.

[0026] The second housing 200 is equipped with cylinders 500 on both sides. The push rod of the cylinder 500 is hinged to the housing cover 400. The cylinders 500 are used to control the housing cover 400 to move closer to or away from the first housing 100. The cylinders 500 are located on both sides of the second cylinder 500. The cylinders 500 are used to open or close the housing cover 400. The fact that the second housing 200 is equipped with cylinders 500 on both sides makes the opening and closing of the housing cover 400 stable.

[0027] In some embodiments, refer to Figure 1 and Figure 3 The second housing 200 is equipped with a handle 210, which is used to lift the second housing 200 closer to or away from the first housing 100. The second housing 200 is hinged to the first housing 100. It can be understood that since the first housing 100 contains the external circuit equipment of the tester 300, when the external circuit equipment of the tester 300 malfunctions, the maintenance personnel can directly lift the second housing 200 through the handle 210 to move the second housing 200 away from the first housing 100, so as to facilitate the maintenance of the external circuit of the tester 300 in the first housing 100. After the maintenance is completed, the maintenance personnel can use the handle to put the second housing 200 back on top of the first housing 100.

[0028] In some embodiments, refer to Figure 1 , Figure 4 and Figure 5 The first housing 100 is provided with an air inlet 110 and an air outlet 120. The air inlet 110 is used for an external blower to blow air into the first housing 100, and the air outlet 120 is used to exhaust the gas inside the first housing 100. The external circuit of the tester 300 is installed inside the first housing 100. When the tester 300 is running under closed conditions for a long time, the temperature inside the first housing 100 will rise, and it is necessary to cool down the inside of the first housing 100 to avoid the temperature inside the first housing 100 becoming too high. It is understandable that circulating water cooling pipes or circulating oil cooling pipes can be installed around the circuit, but considering the risk of leakage of circulating water cooling pipes or circulating oil cooling pipes, air cooling is the most suitable method.

[0029] In some embodiments, refer to Figure 1 and Figure 4 Both sides of the first chamber 100 are provided with exhaust vents 120. The exhaust vents 120 on both sides of the first chamber 100 can avoid dead zones in gas flow, so that the first chamber 100 can be cooled down sufficiently and the cooling effect can be guaranteed. It can be understood that the size and number of exhaust vents 120 can be controlled according to the size of the chamber and the gas flow rate inside the first chamber 100. It is necessary to ensure that the exhaust vents 120 on both sides of the first chamber 100 are symmetrically arranged to increase the cooling efficiency.

[0030] In some embodiments, refer to Figure 4 and Figure 5 A temperature tester 130 is provided on the outside of the first chamber 100. The temperature tester 130 is used to test the temperature inside the first chamber 100. The temperature tester 130 can test the temperature inside the first chamber 100 in a timely manner and issue an alarm when the temperature inside the first chamber 100 reaches the set threshold to warn the operator and avoid the temperature inside the first chamber 100 from being too high and causing an accident. Temperature calibration is a standard setting in this field and will not be extended further.

[0031] In some embodiments, refer to Figure 1 and Figure 4 Pull rings 140 are provided on both sides of the first housing 100. The pull rings 140 are used to lift the first housing 100. The pull rings 140 facilitate lifting the first housing 100, thereby lifting the entire PCBA testing device. It is understood that when moving this PCBA testing device, the operator holds the pull rings 140 to facilitate moving this PCBA testing device. The pull rings 140 are common technology in the art and will not be elaborated further.

[0032] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4The second housing 200 is equipped with an anti-pinch device 600 at the front. The anti-pinch device 600 is a photoelectric beam detector, which is electrically connected to a cylinder 500. When the photoelectric beam detector is blocked, the cylinder 500 stops moving. The photoelectric beam detector is electrically connected to the cylinder 500 and is processed by a sensor. When the photoelectric beam detector detects that it is blocked, it transmits a signal to the sensor, causing the cylinder 500 to stop extending and retracting, thus protecting the operator. It is understood that the anti-pinch device 600 can also be set as other devices, such as infrared thermal imaging detectors and laser intrusion detectors.

[0033] In some embodiments, refer to Figures 3 to 5 The bottom of the first box 100 is provided with several support feet 700. The support feet 700 are used to support the box. The box is made of metal, which is prone to corrosion when placed on the ground for a long time, and friction will be caused during transportation, thus damaging the first box 100. The support feet 700 are detachably set on the lower side of the first box 100. The bottom of the support feet 700 is made of wear-resistant material. After the support feet 700 are worn and unusable, they can be removed and replaced. The support feet 700 also have the function of adjusting the height. Generally, there are four support feet 700.

[0034] In some embodiments, refer to Figure 2 The first test board 310 is provided with a number of buffers 312, which are arranged along the edge of the mounting space 311. The buffers 312 are used to buffer the impact force of the second test board 320 on the second test board 320, and to help the test pins on the second test board 320 align with the test points on the PCBA board under test mounted on the first test board 310, so as to avoid damage to the test pins due to excessive impact force or mechanical damage to the test points on the PCBA board under test due to excessive impact force.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
