Description

Jig with retractable probe

The invention relates to a clamping device, and in particular to a clamp having a retractable probe.

The panel and various electronic components (hereinafter referred to as the object to be tested) are electrically tested during the production process to test whether the function of the object to be tested and the function of the conductive pins are normal. For example, the test of the panel includes lighting and liquid crystal alignment. In the test, the pneumatic clamp is usually used to clamp the fixed panel, and the probe connected to the pneumatic clamp is the conductive pin of the opposite panel, and then the probe is transported. Corresponding control signal or power signal to test whether the function corresponding to the conductive pin is normal.

In fact, when the pneumatic clamp holds the panel, it is necessary to consider not only whether the pneumatic clamp actually holds the fixed panel, but also to avoid excessive force on the panel. Therefore, the current pneumatic gripper usually adds elastic spacers on the clamping block. For example, an elastic material such as engineering rubber or engineering plastic is used as a buffer.

In addition, the test is to synchronize the various conductive pins of the test panel. Therefore, the above-mentioned elastic spacers can only avoid excessive clamping of the panel, which causes damage to the panel, and cannot ensure that the tips of the fixed probes can be electrically connected. The conductive pins of the panel.

In view of the above-mentioned deficiencies, the purpose of the jig of the present invention is to provide a jig having a retractable probe to ensure that the probe of the jig securely holds the object to be tested and is electrically connected to the conductive pin of the object to be tested.

To achieve the above object, the jig of the present invention includes a first clamping device, a second clamping device, and a driving device. The first clamping device includes a clamping block and a plurality of first retractable probes. The first retractable probes are fixedly connected to the first clamping block, and the tips of the first retractable probes are movable for telescopic movement. The second clamping device includes a second clamping block. Tip of the first retractable probe It is towards the second clamp. The driving device connects the first clamping device and the second clamping device, and drives the first clamping device and the second clamping device to move.

Therefore, the driving device of the present invention drives the first clamping device to move to the second clamping device to clamp and fix the object to be tested. Since the tip of the first retractable probe is telescopically movable, the needle tip contacts the object to be tested. Even if the driving device drives the first clamping device to move toward the second clamping device, the tip of the first telescopic probe does not exert excessive force on the object to be tested to avoid damage of the object to be tested.

The detailed construction, features, assembly or use of the jig provided by the present invention will be described in the detailed description of the subsequent embodiments. However, it should be understood by those of ordinary skill in the art that the present invention is not limited by the scope of the invention.

The second clamping block 151 is connected to the second slider 117 and faces the first clamping block 131. The second telescopic probes 153 are fixedly connected to the second clamping block 151, respectively, and are arranged at intervals. The needle tips 1531 of the second telescopic probes 153 are telescopically movable.

There are three ways to drive the pneumatic cylinder 113. The first one is to drive the first slider 115 to move up or down, and the second slider 117 is fixed. The second type is that the first slider 115 is fixed, and the second is The slider 117 is driven to move up or down. The third way is to synchronously drive the first slider 115 and the second slider 117 to form a clamping, or synchronously drive the first slider 115 and the second slider. 117 is far away and forms a release.

It should be noted that, in the embodiment, the first slider 115 and the second slider 117 are respectively located below and above, but the first slider may also be located above, and the second slider may also be located. Below, therefore, the positional interpretation of the first slider and the second slider is not limited to the description of the embodiment.

In addition, the first retractable probes 133 are electrically connected to the corresponding electric wires 30 one-to-one, and the second retractable probes 153 are also electrically connected to the corresponding electric wires 50 one-to-one. The wires 30, 50 are used to transmit control signals or power signals. The first retractable probes 133 and the second retractable probes 153 have the same structure, and then FIG. 2 details the structure of the first retractable probes 133, and since they are the same structure, they are no longer The structure of the second retractable probe 153 will be described.

As shown in FIG. 2, this figure is a cross-sectional view of the first retractable probe 133. The first retractable probe 133 is made of a conductive material such as copper or silver.
