Description

Technical Field

[0001] The present invention relates to the technical field of connector insertion detection, and specifically relates to a connector detection system. Background Art

[0002] With the development of technology, the degree of electrification of automobiles is getting higher and higher. A large number of wire harnesses are required to connect various electrical appliances in an automobile. Connectors are provided between these wire harnesses. The function of the connector is to: build a communication bridge between the interrupted or isolated circuits in the circuit, so that the current can flow through and the circuit can achieve the predetermined function. During the production and processing of the connector, various performance tests need to be carried out on it. Generally, its sensitivity and conductivity are mostly detected. And in order to ensure that each connector can meet the insertion requirements, it is also necessary to perform insertion detection on each processed connector.

[0003] The connector includes a male connector and a female connector. The male connector and the female connector are inserted into each other to achieve connection. The male connector needs to be inserted and detected with a female fixture having the same shape as the female connector. When the male connector and the female fixture can complete the insertion, it means that the male connector is qualified. Similarly, the female connector needs to be inserted and detected with a male fixture having the same shape as the male connector. When the female connector and the male fixture complete the insertion, it means that the female connector is qualified. At present, the above detection method still uses manual detection, with low detection efficiency and time-consuming, and cannot meet the current batch detection requirements.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] As Figures 1 to 6 shown, the present invention includes the following embodiments:

[0028] Embodiment 1: A connector detection system includes a base 1 and feet 11 fixedly connected to the lower surface of the base 1; a vertical plate 2 is fixedly connected to the upper surface of the base 1; a lower driving roller 21 and a lower driven roller 22 are rotatably connected to one side of the vertical plate 2; a lower motor 23 is fixedly connected to the other side of the vertical plate 2; the output shaft of the lower motor 23 is fixedly connected to one end of the lower driving roller 21; a lower conveyor belt 3 is drivingly connected to the outer walls of the lower driving roller 21 and the lower driven roller 22; an upper driving roller 41 and an upper driven roller 42 are rotatably connected to one side of the vertical plate 2; the upper driving roller 41 is driven by an upper motor 43; an upper conveyor belt 5 is drivingly connected to the outer walls of the upper driving roller 41 and the upper driven roller 42; the upper conveyor belt 5 is located above the lower conveyor belt 3; the length of the upper conveyor belt 5 is less than that of the lower conveyor belt 3, and the upper conveyor belt 5 is located at the middle section of the lower conveyor belt 3; a fixture is detachably connected to the outer wall of the upper conveyor belt 5; a stepped placement groove 61 is provided on the outer wall of the lower conveyor belt 3; a workpiece to be detected is placed in the placement groove 61, and the placement groove 61 on the lower conveyor belt 3 corresponds to the fixture on the upper conveyor belt 5 after movement.

[0029] In this embodiment, an installation seat 51 is provided on the outer wall of the upper conveyor belt 5; the fixture is detachably connected to the installation seat 51; a relief strip 7 is fixedly connected to the surface of the installation seat 51 close to the outer wall of the upper conveyor belt 5; the relief 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 installation seat 51, and the other end is provided with a sliding groove 74; one end of the sliding strip 73 is slidably connected in the sliding groove 74, and the other end is connected to the upper conveyor belt 5; a spring 72 is connected between the bottom of the sliding groove and one end of the sliding strip 73.

[0030] Specifically, before using the detection system to detect the connector, the staff first connects the fixture to the installation seat 51. The connection method between the fixture and the installation seat 51 includes detachable connections such as bonding, bolt connection, and clamping connection. In this way, the corresponding fixture is selected according to the insertion requirements of the connector to be detected. After the fixture is installed, the staff will transport the connector to be detected to the front side position of the detection system. The length of the lower conveyor belt 3 in the front-rear direction is greater than that of the upper conveyor belt 5 in the front-rear direction. As the lower motor 23 and the upper motor 43 operate, the lower motor 23 will drive the lower driving roller 21 to rotate. During the rotation of the lower driving roller 21, it will drive the lower conveyor belt 3 to move. During the movement of the lower conveyor belt 3, it will drive the placement groove 61 on the outer wall to move. The staff will place the male connector or female connector to be detected upside down into the placement groove 61. The placement groove 61 is tightly fitted with the workpiece to be detected to ensure the stability of the workpiece to be detected after placement.

[0031] The height of the workpiece 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 groove 61 and extends to the inner side of the lower conveyor belt 3. As the lower conveyor belt 3 moves, the lower conveyor belt 3 will drive the workpiece to be detected in the placement groove 61 to move backward to the lower side of the upper conveyor belt 5. While the lower motor 23 rotates, the upper motor 43 rotates synchronously. The upper motor 43 will drive the upper driving roller 41 to rotate. During the rotation of the upper driving roller 41, it will drive the upper conveyor belt 5 to move. During the movement of the upper conveyor belt 5, it will drive the avoidance strip 7 and the mounting seat 51 on the outer wall to move. The mounting seat 51 will drive the inspection tool to move. After the upper conveyor belt 5 moves, the inspection tool corresponds to the workpiece to be detected on the lower conveyor belt 3 one by one. In this way, when the inspection tool flips downward with the upper conveyor belt 5, it will face the corresponding workpiece to be detected, and the inspection tool is adapted to the workpiece to be detected;

[0032] During the process of the inspection tool approaching the workpiece to be detected, if the workpiece to be detected is qualified, the inspection tool and the workpiece to be detected can complete the insertion. If the workpiece to be detected is unqualified due to processing or other reasons, the inspection tool cannot complete the insertion with the workpiece to be detected. If the inspection tool and the workpiece to be detected cannot complete the insertion, the inspection tool will react the force to the mounting seat 51, and the mounting seat 51 will transfer the force to the avoidance strip 7. The avoidance strip 7 is composed of a fixed strip 71, a spring 72 and a sliding strip 73. In this way, when the workpiece to be detected is unqualified, the sliding strip 73 will slide in the chute 74 at the other end of the fixed strip 71. In this way, the sliding strip 73 will approach the bottom of the chute 74, so that the spring 72 is compressed and the overall length of the avoidance strip 7 becomes shorter, realizing the avoidance of the inspection tool and preventing the upper conveyor belt 5 from being stuck with the lower conveyor belt 3;

[0033] After the inspection tool and the qualified workpiece to be detected complete the insertion, the lower conveyor belt 3 and the upper conveyor belt 5 will continue to move. When the qualified workpiece to be detected is about to move away from under the upper conveyor belt 5, the upper conveyor belt 5 will drive the inspection tool to flip upward. The workpiece to be detected is tightly fitted with the placement groove 61 to ensure the clamping effect of the workpiece to be detected. When the upper conveyor belt 5 drives the inspection tool to flip upward, it will pull out from the qualified workpiece to be detected, completing the separation of the inspection tool from the qualified workpiece to be detected. The inspection tool will move with the upper conveyor belt 5. After the inspection tool is separated from the detected workpiece, the spring 72 will push the corresponding sliding strip 73 away from the corresponding chute 74, making the length of the avoidance strip 7 return to the initial state; The detected workpiece after the detection will move backward with the movement of the lower conveyor belt 3. Since the lower end of the detected workpiece extends to the inner side of the lower conveyor belt 3, when the outer wall of the lower driven roller 22 contacts the outer wall of the detected workpiece, the outer wall of the lower driven roller 22 will give a reaction force to the detected workpiece, so that the detected workpiece is pushed out of the placement groove 61 under the extrusion of the lower driven roller 22, completing the process of self-unloading. The staff catches the detected workpiece after the detection by hand and completes the sorting;

[0034] In the present invention, the lower conveyor belt 3 drives the workpiece to be detected to move backward, and the upper conveyor belt 5 drives the detecting fixture to approach the workpiece to be detected, thereby completing the automatic connector detection work. Compared with manually inserting the connector, the labor intensity is reduced and the connector detection efficiency is improved.

[0035] Embodiment 2: Adjusting grooves 24 are provided through both sides of the vertical plate 2; an adjusting plate 4 is slidably connected up and down in the adjusting grooves 24; the upper end of the adjusting plate 4 is rotatably connected to a first bolt 44; the first bolt 44 penetrates upward through the vertical plate 2 and is threadedly connected to the vertical plate 2; the upper driving roller 41 and the upper driven roller 42 are rotatably connected to the adjusting plate 4; the outer wall of the upper motor 43 is fixedly connected to the adjusting plate 4; the output shaft of the upper motor 43 is fixedly connected to one end of the upper driving roller 41.

[0036] The staff will adjust the position of the upper conveyor belt 5 according to the thickness of the detecting fixture or the workpiece to be detected, so as to meet different specifications of the workpiece to be detected. Specifically, the first bolt 44 is rotated. When the first bolt 44 is rotated, it will drive the adjusting plate 4 to move up or down in the adjusting groove 24. The upward moving adjusting plate 4 will drive the upper driving 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 it and the lower conveyor belt 3 will increase; similarly, after the adjusting plate 4 moves down, the distance between the upper conveyor belt 5 and the lower conveyor belt 3 will decrease. In this way, by moving the adjusting plate 4 up and down, the distance between the upper conveyor belt 5 and the lower conveyor belt 3 is adjusted to meet the insertion distance requirements of different connectors.

[0037] Embodiment 3: Annular grooves 45 are provided on the outer walls of the upper driving roller 41 and the upper driven roller 42; a pressing strip 52 is provided at a lower position on the inner side of the upper conveyor belt 5; the pressing strip 52 is connected to the vertical plate 2, and the front section and the rear section of the pressing strip 52 are tilted upward and extend into the annular grooves 45; the lower surface of the middle section of the pressing strip 52 is in contact with the inner wall of the upper conveyor belt 5; avoiding grooves 53 are provided through the inner and outer walls of the upper conveyor belt 5; the avoiding strip 7 passes through the avoiding grooves 53 and is movably connected to the avoiding grooves 53; the mounting seat 51 is connected to the outer wall of the upper conveyor belt 5 through an elastic cord 54; the avoiding strip 7 can enter the annular grooves 45; the avoiding strip 7 can contact the pressing strip 52.

[0038] In this embodiment, the shape of the middle section of the pressing strip 52 is corrugated; the end of the avoiding strip 7 far from the mounting seat 51 moves back and forth in the avoiding groove 53 during the contact with the middle section of the pressing strip 52; the elasticity of the spring 72 is greater than the elasticity of the elastic cord 54.

[0039] The elastic cord 54 on the outer wall of the upper conveyor belt 5 will apply a pulling force towards the inner side of the upper conveyor belt 5 to the mounting seat 51. Under the pulling force of the elastic cord 54, the mounting seat 51 contacts the outer wall of the upper conveyor belt 5. The avoidance strip 7 will also extend along the avoidance groove 53 to the inner side of the upper conveyor belt 5 as the mounting seat 51 moves. As the upper conveyor belt 5 drives, the avoidance strip 7 will pass by the upper driven roller 42. 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 drives, the avoidance strip 7 will move above the abutting strip 52 and then enter the annular groove 45 on the outer wall of the upper driving roller 41. The depths of the two annular grooves 45 are both relatively deep, so that neither of the two annular grooves 45 will squeeze the avoidance strip 7, maintaining the contact state between the mounting seat 51 and the outer wall of the upper conveyor belt 5. As the upper conveyor belt 5 drives, the avoidance strip 7 in the annular groove 45 on the outer wall of the upper driving roller 41 will enter below the abutting strip 52, and the mounting seat 51 will also drive the interface direction of the inspection tool to face vertically downward. The avoidance strip 7 moves backward as the upper conveyor belt 5 drives, and the front section and the rear section of the abutting strip 52 tilt upward;

[0040] Under the extrusion of the front section of the abutting strip 52, the avoidance strip 7 will move downward along the avoidance groove 53. During the downward movement of the avoidance strip 7, it will drive the mounting seat 51 and the inspection tool to move downward and pull the corresponding elastic cord 54. During the downward movement of the inspection tool, it will be inserted vertically downward into the workpiece to be detected. Compared with the original way of inserting the inspection tool into the workpiece to be detected during the flipping process, the inspection tool in this embodiment is inserted after flipping. In such an insertion detection method, the inspection tool is easier to insert into the workpiece to be detected, making the insertion detection smoother, and at the same time avoiding the damage caused by flipping and inserting;

[0041] Since the elastic force of the spring 72 is greater than the elastic force of the elastic cord 54, for the qualified workpiece to be detected, the avoidance strip 7 will not shorten to control the insertion of the inspection tool into the workpiece to be detected. For the unqualified workpiece to be detected, the avoidance strip 7 will also shorten for avoidance; As the upper conveyor belt 5 continues to drive, the avoidance strip 7 will enter the middle section of the abutting strip 52. Since the shape of the middle section of the abutting strip 52 is set to be corrugated, the avoidance strip 7 will be in active contact with the corrugated middle section of the abutting strip 52 under the pulling of the elastic cord 54. When the avoidance strip 7 moves from the wave trough to the wave crest of the middle section of the abutting strip 52, the avoidance strip 7 will move upward. When the avoidance strip 7 moves from the wave crest to the wave trough of the middle section of the abutting strip 52, the avoidance strip 7 will move downward. In this way, as the avoidance strip 7 moves backward along with the upper conveyor belt 5 and is in active contact with the abutting strip 52, the avoidance strip 7 will move up and down along the corresponding avoidance groove 53. The avoidance strip 7 will drive the mounting seat 51 and the inspection tool to fluctuate up and down. During the up and down fluctuation of the inspection tool, it will realize the insertion and extraction of the workpiece to be detected back and forth. During the back and forth insertion and extraction of the inspection tool for the workpiece to be detected, the burrs or flash on the joint of the workpiece to be detected can be squeezed open, so that some unqualified detection workpieces can also complete the insertion of the inspection tool, and it also makes the subsequent insertion of some qualified detection workpieces smoother, improving the product quality of the connector;

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] Embodiment 5: The inner and outer walls of the lower conveyor belt 3 are provided with replacement slots 31 penetrating through; a replacement seat 6 is installed in the replacement slot 31; a placement slot 61 is arranged on the replacement seat 6; the replacement seat 6 is provided with a first replacement hole 62 along the width direction of the lower conveyor belt 3; the replacement slot 31 is provided with a second replacement hole 32 along the width direction of the lower conveyor belt 3; the first replacement hole 62 and the second replacement hole 32 are arranged corresponding to each other, and a replacement rod 33 is inserted into both of them.

[0047] Before using the detection system, the staff will make different types of replacement seats 6 according to the shape of the part to be detected. The placement slots 61 on the replacement seats 6 are adapted to the parts to be detected and are installed according to requirements. Specifically, the replacement seat 6 is placed into the replacement slot 31, and the replacement rod 33 is inserted into the corresponding first replacement hole 62 and the second replacement hole 32 simultaneously to complete the installation of different types of replacement seats 6 to be applicable to the detection of different types of connectors. Similarly, the mounting seat 51 can also be replaced and installed with the detecting tool by means of clamping or the like.
