Connectors are installed between these wiring harnesses. The function of the connector is to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. During the production and processing of connectors, it is necessary to conduct various performance tests on them. Generally, most of them will be tested for their sensitivity and conductivity. In order to ensure that each connector can meet the plug-in requirements, each connector after processing needs to be plug-in tested.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figures 1 to 6 As shown, the present invention includes the following embodiments: Embodiment 1: A connector detection system, comprising a base 1 and a support leg 11 fixedly connected to the lower surface of the base 1; the upper surface of the base 1 is fixedly connected to a vertical plate 2; one side of the vertical plate 2 is rotatably connected to a lower active roller 21 and a lower driven roller 22; the other side of the vertical plate 2 is fixedly connected to a lower motor 23; the output shaft of the lower motor 23 is fixedly connected to one end of the lower active roller 21; the outer walls of the lower active roller 21 and the lower driven roller 22 are transmission-connected to a lower conveyor belt 3; one side of the vertical plate 2 is rotatably connected to an upper active roller 41 and an upper driven roller 42; The upper active roller 41 is driven by the upper motor 43; the outer walls of the upper active roller 41 and the upper driven roller 42 are connected to the upper conveyor belt 5 by transmission; the upper conveyor belt 5 is located above the lower conveyor belt 3; the upper conveyor belt 5 is shorter than the lower conveyor belt 3, and the upper conveyor belt 5 is located in the middle of the lower conveyor belt 3; the outer wall of the upper conveyor belt 5 is detachably connected to the inspection tool; the outer wall of the lower conveyor belt 3 is provided with a stepped placement groove 61; the placement groove 61 is used to place the parts to be inspected, and the placement groove 61 on the lower conveyor belt 3 corresponds to the inspection tool on the upper conveyor belt 5 after moving.

[0022] In this embodiment, a mounting seat 51 is provided on the outer wall of the upper conveyor belt 5; the inspection fixture can be disassembled and connected to the mounting seat 51; the side of the mounting seat 51 close to the outer wall of the upper conveyor belt 5 is fixedly connected to the avoidance strip 7; the avoidance strip 7 is composed of a fixed strip 71, a spring 72 and a sliding strip 73; one end of the fixed strip 71 is fixedly connected to the mounting seat 51, and the other end is provided with a slide groove 74; one end of the sliding strip 73 is slidably connected in the slide groove 74, and the other end is connected to the upper conveyor belt 5; the bottom of the sliding groove and one end of the sliding strip 73 are connected by a spring 72.

[0023] Specifically, before using the detection system to detect the connector, the staff first connects the inspection fixture to the mounting seat 51. The connection method between the inspection fixture and the mounting seat 51 includes detachable connections such as bonding, bolt connection, and clamping connection. In this way, the corresponding inspection fixture is selected according to the plug-in requirements of the connector to be detected. After the inspection fixture is installed, the staff will transport the connector to be detected to the front side of the detection system. The front-to-back length of the lower conveyor belt 3 is greater than the front-to-back length of the upper conveyor belt 5. With the operation of the lower motor 23 and the upper motor 43, the lower motor 23 will drive the lower active roller 21 to rotate. During the rotation of the lower active roller 21, the lower conveyor belt 3 will be driven to transmit. During the transmission of the lower conveyor belt 3, the placement groove 61 on the outer wall will be driven to move. The staff will place the male connector or female connector to be detected upside down in the placement groove 61. The placement groove 61 is tightly matched with the part to be detected to ensure the stability of the part to be detected after placement; The height of the piece to be detected is greater than the thickness of the lower conveyor belt 3, so that the lower end of the connector passes through the placement slot 61 and extends to the inner side of the lower conveyor belt 3. With the transmission of the lower conveyor belt 3, the lower conveyor belt 3 will drive the piece to be detected in the placement slot 61 to move backward to the bottom of the upper conveyor belt 5. When the lower motor 23 rotates, the upper motor 43 rotates synchronously. The upper motor 43 will drive the upper active roller 41 to rotate. The upper active roller 41 will drive the upper conveyor belt 5 to be driven during its rotation. The upper conveyor belt 5 will drive the avoidance strip 7 and the mounting seat 51 on the outer wall to move during its transmission. The mounting seat 51 will drive the inspection tool to move. After the upper conveyor belt 5 is driven, the inspection tool will correspond to the piece to be detected on the lower conveyor belt 3 one by one. In this way, the inspection tool will face the corresponding piece to be detected as the upper conveyor belt 5 turns downward, and the inspection tool is adapted to the piece to be detected. When the inspection tool approaches the part to be inspected, if the part to be inspected is qualified, the inspection tool and the part to be inspected can be plugged in. If the part to be inspected is unqualified due to processing or other reasons, the inspection tool cannot be plugged in with the part to be inspected. If the inspection tool and the part to be inspected cannot be plugged in, the inspection tool will react force to the mounting seat 51, and the mounting seat 51 will transmit force to the avoidance bar 7. The avoidance bar 7 is composed of a fixed bar 71, a spring 72 and a sliding bar 73. In this way, when the part to be inspected is unqualified, the sliding bar 73 will slide in the slide groove 74 at the other end of the fixed bar 71. In this way, the sliding bar 73 will approach the bottom of the slide groove 74, so that the spring 72 is compressed, and the overall length of the avoidance bar 7 becomes shorter, so as to achieve the avoidance of the inspection tool and avoid the upper conveyor belt 5 from getting stuck with the lower conveyor belt 3. After the inspection tool and the qualified part to be inspected are connected, the lower conveyor belt 3 and the upper conveyor belt 5 will continue to drive. When the qualified part to be inspected is about to be removed from under the upper conveyor belt 5, the upper conveyor belt 5 will drive the inspection tool to flip upward, and the part to be inspected is tightly matched with the placement groove 61 to ensure the clamping effect of the part to be inspected. During the process of the inspection tool driven by the upper conveyor belt 5 to flip upward, it will be pulled off from the qualified part to be inspected, completing the separation of the inspection tool and the qualified part to be inspected. The inspection tool will be driven along with the upper conveyor belt 5. After the inspection tool is separated from the inspection part, the spring 72 will push The corresponding sliding bar 73 moves away from the corresponding sliding groove 74, so that the length of the avoidance bar 7 returns to the initial state; the detection piece that has completed the inspection will move backward with the transmission of the lower conveyor belt 3. Since the detection piece extends to the inner side of the lower conveyor belt 3 at the lower end, the outer wall of the lower driven roller 22 will give the detection piece a reaction force during the contact between the detection piece and the outer wall of the lower driven roller 22, so that the detection piece is moved out of the placement groove 61 under the pressure of the lower driven roller 22, completing the self-unloading process. The staff will catch the detection piece after the inspection by hand and complete the sorting; The present invention drives the inspected part to move backward by the lower conveyor belt 3, and cooperates with the upper conveyor belt 5 to drive the inspection tool close to the inspected part, thereby completing the automated connector inspection work. Compared with manual connector plugging work, the labor intensity is reduced and the connector inspection efficiency is improved.

[0024] Embodiment 2: Adjustment grooves 24 are provided on both sides of the vertical plate 2; the adjustment plate 4 is connected to the adjustment groove 24 in a sliding manner up and down; the upper end of the adjustment plate 4 is rotatably connected to the first bolt 44; the first bolt 44 penetrates the vertical plate 2 upward and is threadedly connected to the vertical plate 2; the upper active roller 41 and the upper driven roller 42 are rotatably connected to the adjustment plate 4; the outer wall of the upper motor 43 is fixedly connected to the adjustment plate 4; the output shaft of the upper motor 43 is fixedly connected to one end of the upper active roller 41.

[0025] The staff will adjust the position of the upper conveyor belt 5 according to the thickness of the inspection fixture or the thickness of the workpiece to be inspected, so as to meet the needs of workpieces to be inspected of different specifications. Specifically, the first bolt 44 is screwed, and the first bolt 44 will drive the adjustment plate 4 to move up or down in the adjustment slot 24. The upward adjustment plate 4 will drive the upper active roller 41 and the upper driven roller 42 to move up, so that the upper conveyor belt 5 moves up. After the upper conveyor belt 5 moves up, the distance between the upper conveyor belt 5 and the lower conveyor belt 3 will be increased; similarly, after the adjustment plate 4 moves down, the distance between the upper conveyor belt 5 and the lower conveyor belt 3 will be reduced. In this way, the distance between the upper conveyor belt 5 and the lower conveyor belt 3 is adjusted by moving the adjustment plate 4 up and down to meet the plug-in spacing requirements of different connectors.

[0026] Embodiment 3: An annular groove 45 is provided on the outer wall of the upper active roller 41 and the outer wall of the upper driven roller 42; a resistance bar 52 is provided on the lower inner side of the upper conveyor belt 5; the resistance bar 52 is connected to the vertical plate 2, and the front and rear sections of the resistance bar 52 are tilted upward and extend into the annular groove 45; the lower surface of the middle section of the resistance bar 52 is in contact with the inner wall of the upper conveyor belt 5; an avoidance groove 53 is provided through the inner and outer walls of the upper conveyor belt 5; the avoidance bar 7 passes through the avoidance groove 53 and is movably connected to the avoidance groove 53; the mounting seat 51 is connected to the outer wall of the upper conveyor belt 5 by an elastic rope 54; the avoidance bar 7 can enter the annular groove 45; the avoidance bar 7 can contact with the resistance bar 52.

[0027] In this embodiment, the middle section of the support bar 52 is wavy in shape; the end of the avoidance bar 7 away from the mounting seat 51 moves back and forth in the avoidance groove 53 during the contact process of the middle section of the support bar 52; the elastic force of the spring 72 is greater than the elastic force of the elastic rope 54.

[0028] The elastic rope 54 on the outer wall of the upper conveyor belt 5 will give the mounting seat 51 a pulling force toward the inner side of the upper conveyor belt 5. The mounting seat 51 will contact the outer wall of the upper conveyor belt 5 under the pulling force of the elastic rope 54. The avoidance strip 7 will also extend to the inner side of the upper conveyor belt 5 along the avoidance groove 53 as the mounting seat 51 moves. The avoidance strip 7 will pass through the upper driven roller 42 as the upper conveyor belt 5 is driven. The avoidance strip 7 will enter the annular groove 45 on the outer wall of the upper driven roller 42. As the upper conveyor belt 5 is driven, the avoidance strip 7 will move above the stop strip 52, and then Entering the annular groove 45 on the outer wall of the upper active roller 41, the depth of the two annular grooves 45 is relatively deep, so that the two annular grooves 45 will not squeeze the avoidance strip 7, and the mounting seat 51 is kept in contact with the outer wall of the upper conveyor belt 5. With the transmission of the upper conveyor belt 5, the avoidance strip 7 in the annular groove 45 on the outer wall of the upper active roller 41 will enter below the stop strip 52, and the mounting seat 51 will also drive the interface direction of the inspection fixture vertically downward, and the avoidance strip 7 moves backward with the transmission of the upper conveyor belt 5, and the front section and rear section of the stop strip 52 are tilted upward; Under the pressure of the front section of the stop bar 52, the avoidance bar 7 will move downward along the avoidance groove 53. During the downward movement of the avoidance bar 7, the mounting seat 51 and the inspection tool will be driven downward and the corresponding elastic rope 54 will be pulled. During the downward movement of the inspection tool, it will be vertically inserted into the inspection object downward. Compared with the original method of inserting the inspection tool into the inspection object during the flipping process, the inspection tool in this embodiment is plugged in after flipping. This plug-in detection method makes it easier for the inspection tool to be inserted into the inspection object, making the plug-in detection smoother and avoiding damage caused by flipping and plugging. Since the elastic force of the spring 72 is greater than the elastic force of the elastic rope 54, for a qualified part to be detected, the avoidance bar 7 will not be shortened to control the inspection fixture and the part to be detected to be inserted, and for an unqualified part to be detected, the avoidance bar 7 will also be shortened to avoid it; as the upper conveyor belt 5 continues to drive, the avoidance bar 7 will enter the middle section of the stop bar 52, and since the shape of the middle section of the stop bar 52 is configured to be corrugated, the avoidance bar 7 will be pulled by the elastic rope 54. In the process of the avoidance bar 7 moving from the low point of the corrugation in the middle section of the stop bar 52 to the high point, the avoidance bar 7 will move up, and the avoidance bar 7 will move from the high point of the corrugation in the middle section of the stop bar 52 to the low point of the corrugation in the middle section of the stop bar 52. In the process of moving from one point to the lowest point, the avoidance bar 7 will move downward. In this way, as the upper conveyor belt 5 moves backward and contacts with the stop bar 52, the avoidance bar 7 will move up and down along the corresponding avoidance groove 53. The avoidance bar 7 will drive the mounting seat 51 and the inspection fixture to fluctuate up and down. During the up and down fluctuation of the inspection fixture, the inspection piece can be plugged in and out back and forth. During the back and forth plugging and pulling of the inspection fixture, the burrs or flash of the joint of the inspection piece can be squeezed out, so that some unqualified inspection pieces can also complete the insertion of the inspection fixture, and some qualified inspection pieces can be more smoothly plugged in later, thereby improving the product quality of the connector; As the upper conveyor belt 5 continues to drive, the avoidance bar 7 will enter the rear section of the stop bar 52, and the mounting seat 51 will move upward under the pull of the elastic rope 54, and the avoidance bar 7 will start to move upward. After the inspection fixture moves upward, it will be pulled out from the detection part. Compared with the original method of pulling the inspection fixture out of the detection part during the flipping process, the method of pulling the inspection fixture out of the detection part is smoother, so that the connector detection stability is improved; then the avoidance bar 7 enters the annular groove 45 on the outer wall of the upper driven roller 42 as the upper conveyor belt 5 drives.

[0029] Embodiment 4: Two clamping seats 8 are provided on the inner side of the lower conveyor belt 3; the length direction of the two clamping seats 8 is consistent with the front-to-back direction; the clamping seat 8 is located directly below the upper conveyor belt 5; the upper surface of the clamping seat 8 is connected to the elastic belt 82 through a roller 81; the end of the detection piece located on the inner side of the lower conveyor belt 3 can enter between the two elastic belts 82; the distance between the two elastic belts 82 is smaller than the specification of the end of the detection piece.

[0030] In this embodiment, a screw 83 and a sliding rod 84 are laterally penetrated by the two clamping seats 8; the screw 83 is threadedly connected to the clamping seat 8; the sliding rod 84 is slidably connected to the clamping seat 8; the threads at both ends of the screw 83 are opposite; the screw 83 and the screw 83 are both rotatably connected to the vertical plate 2.

[0031] The staff will adjust the distance between the two elastic bands 82 according to the specifications of the ends of the detection piece, specifically by turning the screw 83 to drive the two clamping seats 8 to move closer or farther away from each other. This mechanism is a screw slider pair, and the elastic band 82 is a belt-shaped object made of elastic material. The elastic band 82 is transmitted on the roller 81. When the distance between the two elastic bands 82 is slightly smaller than the size of the end of the detection piece, the detection of the connector will then begin. The staff will place the piece to be detected into the placement groove 61, and the end of the piece to be detected will extend through the placement groove 61 to the inner side of the lower conveyor belt 3. As the lower conveyor belt 3 is driven, the end of the piece to be detected will enter between the two elastic bands 82. The size of the end of the piece to be detected is slightly larger than the two The elastic belt 82 has a spacing, and the elastic belt 82 has elastic deformation, so that the end of the to-be-detected piece can be clamped. The to-be-detected piece will move backward with the transmission of the lower conveyor belt 3, and the elastic belt 82 is transmitted on the roller 81, so that the contact position between the detection piece and the outer wall of the elastic belt 82 will not change, thereby ensuring the clamping effect of the end of the detection piece. In this way, when the inspection tool is pulled out from the detection piece, the detection piece will not be separated from the placement groove 61, making the detector detection more stable; after the detection piece is moved away from under the upper conveyor belt 5, the detection piece will also be separated from the contact with the elastic belt 82, releasing the clamping of the end of the detection piece, so that the detection piece can be moved out of the placement groove 61 under the squeezing of the outer wall of the lower driven roller 22.

[0033] Before using the detection system, the staff will prepare different types of replacement seats 6 according to the shape of the part to be detected. The placement groove 61 on the replacement seat 6 is adapted to the part to be detected and installed according to needs. Specifically, the replacement seat 6 is placed in the replacement groove 31, and the replacement rod 33 is inserted into the corresponding first replacement hole 62 and the second replacement hole 32 at the same time to complete the installation of different types of replacement seats 6 to suit different types of connector detection.
