[0022] Example 2: An automatic testing mechanism for chip programming includes: a substrate 1 and a test unit 2 and a three-axis drive unit 3 respectively mounted on the substrate 1. At least two spaced vacuum nozzles 4 are mounted on the Z-axis movable block 31 of the three-axis drive unit 3.

[0025] The aforementioned vacuum nozzle 4 is also used to transport the tested chips in the test unit 2 to the material handling platform 6.
[0026] When used in conjunction with a programming device:
[0027] The chip to be programmed is sequentially transferred from the tray or tape to the programming unit of the programming equipment by the pick-up unit for programming. After programming is completed, the chip to be programmed in the programming unit is sequentially transferred to the empty tray or tape for subsequent unloading operations by the pick-up unit.
[0028] The burning devices mentioned above all fall within the existing basic scope, and the applicant's prior applications have provided specific technical solutions, which will not be repeated in this patent.
[0029] Importantly, during the chip programming process, a random inspection of the programmed chips is necessary to check the accuracy of the programmed information and prevent errors caused by human error, computer viruses, software mutations, or other factors. The specific process is as follows:
[0030] During the normal burning process, perform the following operations at regular intervals (e.g., every hour):
[0031] The horizontal transport module moves the material transport platform to the side of the programming equipment. The picking unit of the programming equipment randomly selects the chip that has been programmed in the programming unit and transports it to the material transport platform.
[0032] The horizontal transport module then moves the transport platform carrying the programmed chip to above the substrate. Next, the vacuum nozzle driven by the three-axis drive unit moves the programmed chip on the transport platform to the test unit for testing. Based on the test results, the tested chip is moved to a specific location (such as a qualified product box, an NG product box, or a discharge tray). The test unit and test process described above are all within the scope of existing technology and will not be elaborated here.
[0033] During the aforementioned testing process, the test socket needs to be pressed and released using the movable cover plate to achieve electrical connection and disconnection between the test socket and the test carrier. The guide post and spring settings can buffer the force of the cylinder that drives the movable cover plate to move up and down, ensuring that the movable cover plate elastically presses the test socket, avoiding damage to the test socket and the chip inside the test socket, and ensuring the stability of the performance of the sampled qualified products.
[0034] When using the aforementioned automatic chip programming testing mechanism, it can randomly and automatically sample and inspect the programmed chips at any time during the programming process without stopping the programming process. This can improve production efficiency and ensure the yield rate throughout the programming process. Furthermore, in the process of pressing and releasing the test socket through the movable cover to realize the electrical conduction and disconnection between the test socket and the test carrier, the test unit ensures that the movable cover elastically presses the test socket, avoiding damage to the test socket and the chip inside the test socket, and ensuring the stability of the performance of the sampled qualified products.
[0035] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
