[0017] The present invention belongs to the core part of the flexible FPC electrical testing machine, and mainly realizes the automatic bearing of the flexible FPC and the continuous clamping and positioning of the gold finger during the electrical testing process. Specifically, in view of the product characteristics of the flexible FPC, the present invention uses a plate-like FPC support as a bearing structure, and uses a first groove body and a second groove body that are recessed downwards on the FPC support as bearing spaces for the FPC belt body and the gold finger, respectively. The groove bottoms of the first groove body and the second groove body are provided with a plurality of suction nozzles, which are connected to the air path inside the FPC support, and are connected to an external vacuum generator through an air inlet nozzle provided on the side wall of the FPC support, so that a vacuum negative pressure is generated inside the first groove body and the second groove body to adsorb and fix the FPC belt body and the gold finger.The special feature is that, based on the need to connect the gold finger to the test circuit during the test process, a socket portion is provided at the bottom of the second slot body, and a plurality of sockets that pass through the socket portion corresponding to the conductive contacts of the gold finger are provided, and during the test process, the detection probe passes through the socket and contacts the conductive contacts of the gold finger to connect it to the test circuit; based on the flexible characteristics of the flexible FPC itself and the requirements for taking and placing the flexible FPC during the material replacement process, the widths of the first slot body and the second slot body are respectively greater than the widths of the FPC tape body and the gold finger; therefore, after the gold finger is placed in the second slot body, it cannot be guaranteed that its conductive contact surface is aligned one by one with the socket; based on this situation, the present invention is provided in the second slot body. A side pressure mechanism is designed to achieve side pressure positioning of the gold finger in the second slot body, so as to control the conductive contacts of the gold finger to be aligned with the sockets one by one; in addition, based on the process requirements of continuous side pressure to maintain the position stability of the gold finger during the test and the need to loosen the gold finger for material placement before and after the test, the side pressure mechanism of the present invention uses a side pressure block that can move freely in the second slot body as a side pressure execution structure. The cross-section of the side pressure block is a T-shaped structure, one side of which is an insert block portion for inserting into the installation slot opened at the bottom of the side pressure support, and the other side is parallel to the side direction of the gold finger and is the side pressure portion. The side pressure block and the side pressure support are connected by an elastic The elastic column is connected with the side pressure support through the movable connection between the elastic column and the side pressure support, and the elastic force inside the elastic column has the tendency to drive the side pressure block to move toward the positioning reference block in the natural state, so that the side pressure block continues to press the gold finger placed between the positioning reference block and the side pressure block, thereby ensuring the stability of the gold finger position during the test; when the gold finger needs to be taken and placed, the conductive drive block inserted on the side pressure support is used as the transmission structure, and the material taking and placing arm must move downward to the FPC support in the process of taking and placing the gold finger. The material taking and placing arm contacts the conductive drive block with the upper protrusion in advance, and continues to press down. The conductive drive block moves downward, and transmits the downward force to the driving slope at the top of the plug-in part of the side pressure block through the driving slope at its bottom. The driving slope is used to convert the downward force in the vertical direction into a thrust in the horizontal direction, so that the side pressure block overcomes the elastic force of the elastic column and moves outward away from the positioning reference block until the second slot is fully opened. At this time, the placement and removal of the flexible FPC are also completed simultaneously. Through the above structure of the side pressure mechanism, under the premise of completing the precise and continuous side pressure positioning of the gold finger during the test, the opening and closing of the second slot is achieved while the gold finger is being placed and removed, without the need to set up a separate opening and closing mechanism, which reduces the manufacturing cost and improves the efficiency of gold finger placement.

The present invention belongs to the core part of the flexible FPC electrical test machine, and mainly realizes the automatic bearing of the flexible FPC and the continuous clamping and positioning of the gold finger during the electrical test. Specifically, in view of the product characteristics of the flexible FPC, the present invention uses a plate-shaped FPC support as a bearing structure, and uses a downwardly recessed first groove body and a second groove body opened on the FPC support as bearing spaces for the FPC belt body and the gold fingers respectively. The groove bottoms of the first groove body and the second groove body are provided with multiple suction nozzles, which are connected to the air path inside the FPC support and are connected to an external vacuum generator through an air inlet nozzle arranged on the side wall of the FPC support, so that a vacuum negative pressure is generated inside the first groove body and the second groove body to adsorb and fix the FPC belt body and the gold fingers.The special feature is that, based on the need to connect the gold finger to the test circuit during the test process, a socket portion is provided at the bottom of the second slot body, and a plurality of sockets that pass through the socket portion corresponding to the conductive contacts of the gold finger are provided, and during the test process, the detection probe passes through the socket and contacts the conductive contacts of the gold finger to connect it to the test circuit; based on the flexible characteristics of the flexible FPC itself and the requirements for taking and placing the flexible FPC during the material replacement process, the widths of the first slot body and the second slot body are respectively greater than the widths of the FPC tape body and the gold finger; therefore, after the gold finger is placed in the second slot body, it cannot be guaranteed that its conductive contact surface is aligned one by one with the socket; based on this situation, the present invention is provided in the second slot body. A side pressure mechanism is designed to achieve side pressure positioning of the gold finger in the second slot body, so as to control the conductive contacts of the gold finger to be aligned with the sockets one by one; in addition, based on the process requirements of continuous side pressure to maintain the position stability of the gold finger during the test and the need to loosen the gold finger for material placement before and after the test, the side pressure mechanism of the present invention uses a side pressure block that can move freely in the second slot body as a side pressure execution structure. The cross-section of the side pressure block is a T-shaped structure, one side of which is an insert block portion for inserting into the installation slot opened at the bottom of the side pressure support, and the other side is parallel to the side direction of the gold finger and is the side pressure portion. The side pressure block and the side pressure support are connected by an elastic The elastic column is connected with the side pressure support through the movable connection between the elastic column and the side pressure support, and the elastic force inside the elastic column has the tendency to drive the side pressure block to move toward the positioning reference block in the natural state, so that the side pressure block continues to press the gold finger placed between the positioning reference block and the side pressure block, thereby ensuring the stability of the gold finger position during the test; when the gold finger needs to be taken and placed, the conductive drive block inserted on the side pressure support is used as the transmission structure, and the material taking and placing arm must move downward to the FPC support in the process of taking and placing the gold finger.

The conductive drive block moves downward, and transmits the downward force to the driving slope at the top of the plug-in part of the side pressure block through the driving slope at its bottom. The driving slope is used to convert the downward force in the vertical direction into a thrust in the horizontal direction, so that the side pressure block overcomes the elastic force of the elastic column and moves outward away from the positioning reference block until the second slot is fully opened. At this time, the placement and removal of the flexible FPC are also completed simultaneously. Through the above structure of the side pressure mechanism, under the premise of completing the precise and continuous side pressure positioning of the gold finger during the test, the opening and closing of the second slot is achieved while the gold finger is being placed and removed, without the need to set up a separate opening and closing mechanism, which reduces the manufacturing cost and improves the efficiency of gold finger placement.
