The invention relates to a crimping device used in the testing and classification of electronic components, which can crimp the electronic components to the testing equipment for testing, so as to complete the testing and classification of the electronic components.

Electronic component testing and classification equipment can be used to test electronic components (such as ICs with solder balls), mainly using classification equipment to take out the electronic components from the electronic component tray one by one or batch by batch, and transfer them to the testing equipment. The equipment to be tested After the test is completed, the sorting equipment sorts and transfers the electronic components according to the test results and places them in designated locations, for example, on several different trays.

In the above-mentioned electronic component testing and classification equipment, since the specifications and dimensions of the electronic components tested in each batch may be different, the size of the test socket of the test equipment and the distance between adjacent test sockets will change according to the electronic component to be tested. In addition, the electronic component The size and spacing of the electronic components in the tray will also be different, resulting in the difference between the spacing of the electronic components in the tray and the spacing during the test, and proper pitch change and alignment are required for the test to proceed smoothly.

Based on the above situation, most of the existing sorting equipment has a pitch changing mechanism. For example, the pitch changing mechanism in the TWI569356 patent and the TWI603821 patent is an example. The pitch changing mechanism can take multiple electronic components from the electronic component tray.
