It should be understood by those skilled in the art that, in the present application, the internal structure of the testing machine 1 is configured as the prior art, and therefore, the detailed description thereof is omitted.
Specifically, as shown in fig. 1 to 2, the plate feeding device 22 includes a slide rail 221, a servo motor 222, and a robot 223, wherein the slide rail 221 is transversely installed above the frame body 21, and the robot 223 is embedded in the slide rail 221 and can move along the slide rail 221. The robot arm 223 is moved laterally along the slide rail 221 by the servo motor 222. Preferably, the servo motor 222 is a stepping motor.

When the driving shaft 2213 is driven to rotate by the servo motor 222, the gear belt 2211 rotates accordingly.
Particularly, the robot arm 223 includes a chain 2231, a material taking assembly 2232 and a fixing frame 2233, wherein the chain 2231 is connected to the end of the fixing frame 2233 and is embedded in the linear track, the material taking assembly is installed on the fixing frame 2233, and the material taking assembly is used for taking a circuit board. The fixed frame is provided with engaging teeth 22331, and the fixed frame 2233 is fixed on the gear belt through the engaging teeth 22331. When the gear belt 2231 is driven by the servo motor 224, the robot arm moves along with it, and thus the circuit board taken by the take-off assembly 2232 moves along with it.
As shown in fig. 3 and 4, the material taking assembly 2232 includes a support 22321, a plurality of suction cups 22322 and an air pressure pipe 22323, wherein one end of the support 22321 is fixed on the fixed frame 2233, a plurality of suction cups 22322 are selectively fixed on the support 22321, the suction cups 22322 are connected to the air pressure pipe 22323, the air pressure pipe 22323 is connected to a vacuum suction device, so that a negative pressure chamber can be formed, and the suction cups 22322 suck the circuit board thereon.
During operation, the suction cup 22322 sucks up the circuit board to be tested on the board collecting device 23 and moves the circuit board to the testing platform 12 of the testing machine 1, thereby completing the feeding process. Since the material taking assembly 2232 includes a plurality of suction cups 22322 distributed in a specific manner, the arrangement and number of the suction cups 22322 can be specifically set according to the size of the circuit board. In other words, when the size of the circuit board is large, the number of the suckers 22322 is only increased moderately without changing the device, so that the adsorption force on the large-sized circuit board is improved, the actions of sucking and releasing the circuit board are accurate and stable, and the test requirement on the large-sized circuit board is met.

It is worth mentioning that, based on common knowledge, the take-out assembly 2232 can only successfully pick up a circuit board at a location that is disposed at a certain height below it due to structural limitations. In other words, when the take-out assembly 2232 picks up a circuit board, it is difficult to pick up the circuit board if the height of the circuit board is much lower than the height of the take-out assembly 2232. In addition, after the circuit boards are detected, when the material taking assembly 2232 places the detected qualified circuit boards and the detected unqualified circuit boards at the designated positions respectively, the height of the material taking assembly 2232 is increased or even exceeds the height of the material taking assembly 2232 along with the increase of the circuit boards at the storage positions, and the automatic feeding testing device is difficult to realize effective arrangement of the detected circuit boards. Therefore, in order to cooperate with the material taking assembly 2232 for taking and placing the material, the moving device 231 of the board collecting device 23 can move longitudinally, so as to adjust the height of the whole stacked circuit boards.
In order to store the circuit boards to be detected and store the detected circuit boards in a classified manner, the board collecting device 23 can be further divided into a qualified board collecting device 23A, an unqualified board collecting device 23B and a board storing device 23C for the boards to be detected, and the qualified board collecting device 23A, the unqualified board collecting device 23B and the board storing device 23C for the boards to be detected are respectively and independently arranged on the frame body.
