Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of testing equipment for testing multiple samples at the same time, in particular to a testing equipment for testing multiple samples at the same time. Background Art
[0002] Flexible Printed Circuit Board (FPC), also known as soft board in Chinese, features lightweight, high wiring density, thin thickness, and easy bending and folding. FPCs are frequently used in consumer electronics such as mobile phones, tablets, VR, AR, and cameras. Their susceptibility to bending and folding has led to the shrinking of these consumer electronics, with the trend continuing. This has forced FPC manufacturers to use thinner and more resistant materials during production. Consequently, existing FPC products are increasingly subject to bending and folding, necessitating faster and more efficient bending and folding testing.
[0003] Existing bending test equipment is usually designed as a single channel due to cost reasons, so that only one group of samples can be tested each time. However, the bending requirements of products now often reach more than 300,000 times, and the bending speed is usually only 30 times / min. Based on this calculation, the time to bend one sample is 166 hours, about 7 days. The time to complete the bending of a group of 5PCS samples is as long as 35 days, which makes the test cycle very long and the efficiency of testing samples low.
[0004] Therefore, in order to address the deficiencies of the prior art, a testing device for testing multiple samples simultaneously is provided. Utility Model Content

[0035] During testing, the fixture 1 type is selected based on the requirements. The fixture 1 connects the bending device 2 and the sample 3 via a connecting wire 4. The fixture 1 includes a device socket group 11, several sample 3 socket groups 12, and an internal wire 13. The internal wire 13 connects the device socket group 11 and the sample 3 socket group 12. The device socket group 11 is connected to the bending device 2 via the connecting wire 4, and several sample 3 socket groups 12 are connected to several samples 3 via the connecting wire 4. By providing multiple sample 3 socket groups 12 within the fixture 1, the bending device 2 can test multiple samples simultaneously. This test equipment for simultaneously testing multiple samples has the characteristic of shortening the testing cycle of the bending test equipment. In this embodiment, the fixture 1 type is selected to have two groups of sample 3 socket groups 12, allowing two groups of samples 3 to be tested simultaneously.
[0036] In one embodiment, the device socket group 11 includes a positive socket 111 and a negative socket 112 , and the positive socket 111 and the negative socket 112 are detachably connected to the positive and negative poles of the bending device 2 respectively through the connecting wire 4 .
[0037] In one embodiment, the socket group 12 of sample 3 includes a first socket 121 and a second socket 122, which are respectively fixedly connected to the positive and negative electrodes of sample 3 via a connecting wire 4. A first plug connector is provided at one end of the connecting wire 4, which is detachably connected to the first socket 121 and / or the second socket 122, and the other end is fixedly connected to sample 3. Sample 3 and connecting wire 4 are connected by welding. Connecting wire 4 is a common and relatively inexpensive consumable. After the test of sample 3 is completed, the wire near one end of sample 3 is directly disconnected. The shortened wire can also be welded to the next sample 3 to be tested.
[0038] In one embodiment, first jack 121 is connected to positive jack 111 or negative jack 112 via an internal wire 13, and second jack 122 is connected to conversion jack 14 via an internal wire 13; alternatively, second jack 122 is connected to a second jack 122 of another sample 3 jack group 12 via an internal wire 13. In this embodiment, two sample 3 jack groups 12 are provided within fixture 1: positive jack 111 is connected to first jack 121 of the first sample 3 jack group 12, and negative jack 112 is connected to first jack 121 of the second sample 3 jack group 12.

The general control system 22 is electrically connected to the fixture 1 and the bending mechanism 21. The bending mechanism 21 is externally connected to the fixture 1.
