Abstract
The embodiment of the present invention discloses a test system for devices on braids. The test system comprises a braid conveying device, a test claw, a fastening device, a linkage device, a test board and a test controller, wherein the braid conveying device is used to convey braid s to the test board; the test pawl is disposed opposite to the test board; the linkage device is used for pushing the test claw to move toward the test board when moving forward and backward so that the test claw presses against the pins of the devices on the braids on the test board; and the test pawl is electrically connected to the test controller through a test circuit for providing test signals to the devices. According to the technical solutions provided in the embodiments of the present invention, automatic test of the devices on braids can be realize. The test system is convenient and quick and improves the efficiency for testing devices on braids.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of detection, and in particular to a testing system for devices on a braid. Background technique [0002] After the electronic device is formed, such as a triode, it is generally taped by a braiding machine. [0003] Existing braiding machine mainly comprises product guide rail, indexing gear plate, the cover plate that is positioned at the indexing gear plate, product forming device, product positioning device and product rejecting device. The product guide rail sends the electronic components one by one between the indexing gear plate and the cover plate. As the indexing gear plate rotates, the tin foil belt rotates with the indexing gear plate. When the device moves to the product forming device, the product is formed. The device processes the pins of the device to open the pins of the device. Then, the device is processed on the product positioning device and glued to the tin f...
