One side of the operating area 11 is provided with a plurality of stoppers 13 , and a side of the stoppers 13 is provided with a pushing device 14 . The ejecting device 14 has a ejecting surface 15 that can move toward the direction of the retaining members 13, so that the liquid crystal panel placed in the operating area 11 can be sandwiched between the retaining members 13 and the ejecting device. Between the top surfaces 15, so as to fix the liquid crystal panel in the first axis direction.

The detection area 12 is set on the base 10 and one side of the operation area 11 . The detection area 12 includes: two fixing mechanisms 20 , two positioning mechanisms 30 and a detection mechanism 40 .

The two fixing mechanisms 20 are disposed on one side of the operating area 11 , and each of the two fixing mechanisms 20 includes: a motor 21 , a rotating shaft 22 , a swing arm 23 and a pressed part 24 . The rotating shaft 22 is connected to the motor 21 , one end of the swing arm 23 is connected to the rotating shaft 22 , and the pressing part 24 is disposed at the other end of the swing arm 23 . Each of the swing arms 23 can be driven by the motor 21 to swing, so that the pressed part 24 swings toward the operating area 11 or away from the operating area 11 . In this embodiment, the two fixing mechanisms 20 are arranged opposite to each other and make the rotating shafts 22 of the two motors 21 face each other, and the pressing part 24 is a round roller-shaped pressing part, but not limited thereto.

Each of the two positioning mechanisms 30 includes: a driver 31 and a push rod 32 , and the push rod 32 is driven by the driver 31 to reciprocate along an axial direction. In this embodiment, the two positioning mechanisms 30 are disposed on one side of the operating area 11 , and the two push rods 32 can protrude or shrink toward the operating area 11 . The driver 31 may be a driving device capable of reciprocating movement along an axial direction, such as a pneumatic cylinder, an oil hydraulic cylinder, etc. The present embodiment uses a pneumatic cylinder as an example but not limited thereto. The two positioning mechanisms 30 are preferably disposed between the two fixing mechanisms 20, but not limited thereto.

The detection mechanism 40 includes: a base 41 and a sliding seat 42 disposed on the base, and a detection joint 43 is disposed on the sliding seat 42 . The detection mechanism 40 is disposed on one side of the operation area 11 , and the sliding seat 42 can move toward or away from the operation area 11 . The detection mechanism 40 can be driven by an external air pressure or oil pressure or an electric motor to move the sliding seat, but since these power sources are not the improved structure of this application, no further description will be given here. The axial direction of the reciprocating movement of the sliding seat 42 is the same as the axial direction of the movement of the two positioning mechanism push rods 32, and the detection mechanism 40 is preferably arranged between the two positioning mechanisms 30 and the axial movement of the sliding seat 42 is the same as the axial direction of the moving of the two positioning mechanisms. The axial directions in which the two push rods 32 move are parallel.

With the above-mentioned structure of the present case, the operation will be described below by taking the detection of a liquid crystal panel as an example.

Firstly, the liquid crystal panel to be tested is placed in the operating area 11 and the slot P on the circuit board to be tested faces the testing area 12 , as shown in FIG. 1 . The ejecting surface 15 of the ejecting device 14 can push away one side of the liquid crystal panel, so that the other side of the liquid crystal panel is pushed against the stoppers 13, so that the liquid crystal panel can be positioned at a position to be detected and A fixation in the first axial direction is achieved.

Then the push rods 32 of the two positioning mechanisms protrude toward the operating area 11, so that the two push rods 32 abut against the side of the circuit board of the liquid crystal panel, so that the liquid crystal panel is fixed in the second axial direction. The swing arms 23 of the two fixing mechanisms swing toward the circuit board of the liquid crystal panel and make the two pressing parts 24 press the circuit board. The circuit board is used to fix the liquid crystal panel on the third axis. Then the sliding seat 42 of the detection mechanism can move towards the circuit board of the liquid crystal panel and the detection joint 43 on the sliding seat can be docked and inserted into the slot P of the circuit board of the liquid crystal panel for detection.

After the detection is completed, the two ejector rods 32 will remain on the position against the circuit board of the liquid crystal panel to allow the sliding seat 42 of the detection mechanism to retreat successively, so that the detection joint 43 is connected to the plug on the circuit board of the liquid crystal panel. The slot P is disconnected. The advantage of this action is that after the detection connector 43 is combined with the slot P, there will be a corresponding engaging structure between the detection connector 43 and the slot P to increase the stability of the combination. property, so the movement of the detection joint 43 may drive the circuit board of the liquid crystal panel to move, so if the two ejector rods 32 are still kept at the position against the circuit board of the liquid crystal panel, the slide seat 42 will move backward The circuit board of the liquid crystal panel will not be pulled to move, and the detection joint 43 can be separated from the slot P effectively. After the detection joint 43 is separated from the slot P, the two ejector rods 32 retreat again, and the swing arms 23 of the two fixing mechanisms 20 rotate again to make the two pressing parts 24 leave the circuit board of the liquid crystal panel, and the ejector device 14 also unclamps the abutment of the liquid crystal panel, and the liquid crystal panel that has been detected can be taken out from the operation area at this time, and a liquid crystal panel to be detected is replaced.

Different from the previous detection devices, the present invention has the advantage that: the first axis, the second axis and the third axis mentioned above in this case are three different and non-parallel axes, and the detection area 12 is set Two different mechanisms, the fixing mechanism 20 and the positioning mechanism 30, can fix the liquid crystal panel circuit board to be tested in two different axial directions, so as to ensure that the circuit board to be tested can be stably fixed during the testing process at the location to be detected. Moreover, after the detection is completed, due to the assistance of the fixing mechanism and the positioning mechanism, the separation of the detection connector and the slot can be made easier, and it can be avoided that the detection connector drags the product to be detected when it moves, causing the slot or liquid crystal to be damaged. Damage to the panel circuit.

In the above-mentioned embodiment, the number of the fixing mechanism and the positioning mechanism is not limited to two, and different matching methods such as one fixing mechanism and one positioning mechanism or three fixing mechanisms and two positioning mechanisms can be used, and the matching method can be determined according to the liquid crystal The size of the panel circuit board is determined.
