[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] like Figures 1 to 15 As shown, a fully automatic assembly machine for automotive connector parts is characterized by including a feeding mechanism 1, used to feed the automotive connector bodies in sequence;

[0046] The workbench 2 has an upper ring track 21, and a plurality of fixing fixtures 22 are provided on the upper side of the ring track 21. The fixing fixtures 22 move along the ring track 21 on the upper side of the ring track 21.

[0047] O-ring assembly mechanism 3 is set on the upper side of workbench 2 and is used to assemble O-rings to the inner side of the automotive connector body;

[0048] The locking spring assembly mechanism 4 is located on the upper side of the worktable 2 and is used to assemble the locking spring to the inner side of the top hole of the car connector body;

[0049] The locking spring insertion / removal detection mechanism 6 is set on the upper side of the workbench 2 and is used to detect whether the locking spring is installed in place;

[0050] The lock spring breakage detection mechanism 6 is set on the upper side of the workbench 2 and is used to detect whether the lock spring is broken.

[0051] The installation and testing structure for O-rings and locking springs is set on the upper side of the annular track 21. In this way, as the main body of the car connector moves into the fixed fixture 22 and moves on the annular track 21, the installation and testing of O-rings and locking springs can be completed in sequence, thereby realizing fully automatic assembly of car connector parts, improving production efficiency and reducing production costs.

[0052] At this time, the feeding mechanism 1 is used to feed the car connector body in sequence. Specifically, the feeding mechanism 1 includes a main body vibrating plate 11, the main body vibrating plate 11 is provided with a main body feeding track 12, and a transfer detection structure 13 is provided on the outside of the main body feeding track 12 for detecting whether the car connector body meets the requirements. A main body feeding moving structure 14 is provided between the transfer detection structure 13 and the main body feeding track 12 for moving the car connector body from the main body feeding track 12 to the transfer detection structure 13. A main body discharge structure 15 is provided on the other side of the transfer detection structure 13 for moving the qualified car connector body to a fixed diameter position on the upper side of the annular track 21. Under the action of the main vibrating plate 11, the car connector body moves sequentially to the main feeding track 12. Then, under the action of the main feeding moving structure 14, the car connector body is moved to the transfer detection structure 13. The car connector body is inspected at the transfer detection structure 13, thus ensuring that the car connector bodies that move to the fixed fixture 22 on the upper side of the circular track 21 meet the requirements. For the car connector bodies that meet the inspection requirements, under the action of the main discharge structure 15, they move from the transfer detection structure 13 to the main discharge structure 15, and then under the action of the main discharge structure 15, they move to the fixed fixture 22 on the circular track 21.

[0053] At this time, the fixing fixture 22 is set on the upper side of the annular track 21 and moves along the direction of the annular track 21. The fixing fixture 22 is provided with positioning holes for positioning the car connector body. After the car connector body is placed on the fixing fixture 22, the four sides of the car connector body can be positioned, so that the top hole of the car connector body faces upward. At the same time, the fixing fixture 22 is provided with slots on the side that correspond to the side holes of the car connector body. This allows the locking spring to move from the slot on the side of the fixing fixture 22 into the side hole of the car connector body, thereby completing the assembly with the car connector body.

[0054] The transfer detection structure 13 is used for the detection of the main body of the automotive connector and also for the classification of the main body of the automotive connector. In this case, the transfer detection structure 13 includes a fixed plate fixed to the upper side of the workbench 2 by a bracket. A rotating disk 131 is provided on the side of the fixed plate via a rotating shaft. Four fixing components 132 are provided on the side of the rotating disk 131, evenly distributed around the center circumference of the rotating disk 131. Each fixing component 132 includes a fixing finger cylinder and a fixing clamp 332 connected to the movable part of the fixing finger cylinder. The claw, the movable part of the fixed finger cylinder faces outward to the outside of the rotating disk 131, the upper side of the rotating disk 131 is provided with a detection component 133, the detection component 133 includes a detection camera fixed to the upper side of the fixed plate by a vertical rod, the middle of the vertical rod is provided with a ring light, the ring light and the detection camera are located on the upper side of the highest point of the rotating disk 131, the lower side of the transfer detection structure 13 is provided with a defective product collection component, the defective product collection component includes a collection groove 134, the collection groove 134 is located on the lower side of the lowest point of the rotating disk 131. The rotating disk 131 is generally circular. A motor for controlling the rotation of the rotating disk 131 is located on the side of the fixed plate. Under the action of the motor, the rotating disk 131 can rotate around the center position. Four fixed components are evenly distributed on the side of the rotating disk 131. On the left and right sides of the rotating disk 131 (outside the arc-shaped edge of the rotating disk 131) are the main feeding moving structure 14 and the main discharging structure 15, respectively. On the upper and lower sides of the rotating disk 131 are the detection component 133 and the collection trough 134, respectively. Thus, on one of the rotating disks 131... When the fixing component 132 (left side position) moves to correspond with the main body feeding moving structure 14 to fix the car connector body to be tested, there is a fixing component 132 fixing another car connector body on the upper side of the rotating disk 131. The detection component 133 is detecting the car connector body on the upper side of the rotating disk 131. The main body discharge structure 15 or collection trough 134 on the right side or the lower side of the rotating disk 131 will classify the detected car connector bodies, thereby completing the detection, classification and feeding process of the car connector bodies.

[0055] For the main body of the automotive connector, O-rings need to be assembled. In this embodiment, the O-ring assembly mechanism 3 includes an O-ring vibrating plate 31. The O-ring vibrating plate 31 is provided with an O-ring feeding track 32. The outer side of the O-ring feeding track 32 is provided with a clamping and moving structure 33 for moving the O-ring from the O-ring feeding track 32 and assembling it onto the main body of the automotive connector of the fixing fixture 22. The clamping and moving structure 33 includes a fixing ring 331. The inner side of the fixing ring 331 is provided with a fixing clamp 332. The fixing clamp 332 includes multiple fixing pieces. The fixing pieces are distributed in a ring on the inner side of the outer ring. There is a gap between adjacent fixing pieces. When the fixing pieces move upward into the inner ring, they retract toward the center. When the fixing pieces move downward into the outer ring, they open outward. The outer side of the fixing pieces is provided with a limiting groove 333. When the fixing pieces move upward and retract within the fixing ring 331, they form an annular groove.

[0056] The locking spring is snapped onto the upper side of the car connector body, located inside the body. If it were directly pressed in through the top hole, it would deform and break. Therefore, in this embodiment, the locking spring assembly mechanism 4 includes a locking spring vibratory plate 41. The vibratory plate 41 has a locking spring feeding track 42, with a heating structure 43 on its upper side for heating and softening the locking spring. A pushing structure 44 is located on the outer side of the loading track 42 to push the locking spring from the side into the car connector body at the fixing fixture 22. A locking spring moving structure 45 is located between the loading track 42 and the pushing structure 44 to move the locking spring from the loading track 42 to the pushing structure 44. In this process, the locking spring is first heated and softened to make it easier to deform and less prone to damage after deformation. Then, it is pushed into the inner position through the side hole on the side of the car connector body, thus completing the locking spring assembly process.

[0057] Specifically, the heating structure 43 includes a heating part 431 located on the upper side of the spring-loaded rail 42. The heating part 431 is a PTC heater. The heating part 431 is spaced apart from the spring-loaded rail 42. A fan 432 is provided on the upper side of the heating part 431 to blow the heat emitted by the heating part 431 toward the position of the spring-loaded rail 42. The PTC heater is located on the upper side of the spring loading track 42. After the PTC heater generates a certain amount of heat, the air is heated. Then, under the action of the fan 432, the hot air is blown to the spring loading track 42. In this way, the spring at the spring loading track 42 softens and deforms under the action of the hot air. At this time, since it is not heated directly in a sealed environment, but through the action of hot air on the surface of the spring, the spring will only soften. Thus, the spring is not easy to break when it deforms. After the spring is assembled into the automotive connector body, it can return to its original hardness after cooling. Therefore, when the automotive connector is in use, the corresponding function of the spring can be used normally.

[0058] After the locking spring is heated and softened, it needs to be assembled into the car connector body from the side. At this time, the pushing structure 44 includes a pushing plate 441. The pushing plate 441 has a pushing groove 442 in the middle. The pushing groove 442 extends to the side wall of the pushing plate 441 to form an opening. The opening is directly opposite the side hole of the car connector body at the fixed fixture 22. The pushing plate 441 has a pushing cylinder 443 on its side. The piston rod of the pushing cylinder 443 is connected to a push rod 444. The width of the pushing groove 442 gradually decreases from the direction of the push rod 444 towards the opening. The width of the opening is adapted to the width of the locking spring after being compressed in the width direction. The push rod 444 moves in the pushing groove 442 to push the locking spring in the pushing groove 442 into the car connector body. Under the action of the locking spring moving structure 45, the locking spring moves from the locking spring loading track 42 to the push groove 442 of the push plate 441. Then, under the action of the push cylinder 443 and the push rod 444, the locking spring moves in the push groove 442 along the direction of the push groove 442. Since the opening on the side of the push groove 442 corresponds to the side hole of the car connector body, the locking spring can be pushed into the interior from the side hole of the car connector body, thereby completing the assembly of the locking spring.

[0059] During the process of the locking spring being pushed into the side hole of the car connector body, since the locking spring cannot enter the inner side of the car connector body at the side hole position without deformation, it needs to deform first as it enters the inner side of the car connector body from the side hole position. This requires compression of the locking spring in the width direction. At this time, the width of the push groove 442 gradually decreases from the direction of the push rod 444 towards the opening direction. The width of the opening position matches the width of the locking spring after compression in the width direction. Because the width of the push groove 442 gradually decreases, during the movement of the locking spring, the locking spring... The spring will be subjected to external force in the direction, resulting in a certain deformation. At the same time, since the width of the opening of the push plate matches the width of the locking spring after being squeezed in the width direction, the locking spring can enter the interior of the car connector body from the side hole after being separated from the push plate. At this time, the push groove 442 forms an opening on the side wall of the push plate 441, that is, an upper pressure plate is formed on the upper side of the opening. This upper position can be used to restrict the locking spring, preventing the locking spring from jumping upward when it is squeezed and deformed on the left and right sides, thus ensuring that the locking spring moves normally in the push groove 442.

[0060] After assembling the locking spring with the car connector body, it is necessary to check whether the locking spring installation meets the requirements, mainly to check whether the locking spring can be easily pulled out. Therefore, in this embodiment, the locking spring insertion and removal detection mechanism 6 includes a clamping assembly 51 for clamping the car connector body in the fixing fixture 22 at the position of the annular track 21. The upper side of the clamping assembly 51 is provided with a pull rod 52 that moves up and down. The pull rod 52 is provided with a pull ring 53 that is larger than the inner diameter of the locking spring. The upper side of the pull rod 52 is connected to a tension gauge 54 through a detection cylinder 55. The tension gauge 54 is fixed on the upper side of the workbench 2 by a bracket. The car connector body at the fixed fixture 22 is clamped by the clamping assembly 51. Then, the pull rod 52 is moved up and down by the detection cylinder 55. When the pull rod 52 moves down, the pull ring 53 on the outside of the pull rod 52 is inserted into the lower side of the middle hole of the lock spring. Then, the pull rod 52 is moved up by the detection cylinder 55. At this time, the piston rod of the detection cylinder 55 is fixed to the pull rod 52, and the cylinder body of the detection cylinder 55 is fixed to the test end of the tension meter 54. Thus, when the piston rod of the detection cylinder 55 controls the pull rod 52 to move up, it is possible to test whether the lock spring is easy to pull out and whether it will break during the insertion of the pull ring 53.

[0061] At this time, in order to increase the overall stroke of the clamping assembly 51, the tension meter 54, the detection cylinder 55 and the pull rod 52, a vertical detection drive structure is also provided on the side to control the overall up and down movement of the clamping assembly 51, the tension meter 54, the detection cylinder 55 and the pull rod 52. At the same time, in order to enable the pull ring 53 to be inserted into the locking spring and to prevent the pull ring 53 from damaging the locking spring during the test, the pull ring 53 is made of an elastic material, such as silicone.

[0062] After the locking spring is installed and the insertion / removal test is completed, the locking spring may break, which will affect the quality of the final product. Therefore, it is necessary to complete the locking spring testing process. In this embodiment, the locking spring breakage detection mechanism 6 includes a first cylinder 61 and a second cylinder 62. The piston rods of the first cylinder 61 and the second cylinder 62 are respectively connected to a first pawl 611 and a second pawl 621. When the first pawl 611 and the second pawl 621 come together, they are inserted into the top hole of the car connector body. The first pawl 611 and the second pawl 621 move outward under the action of the first cylinder 61 and the second cylinder 62. The first pawl 611 and the second pawl 621 are provided with a limiting groove 333 on the outside. The groove 63333 is provided with an abutment part 64 corresponding to the inner side of the locking spring. When the first pawl 611 and the second pawl 621 move outward, the abutment part 64 presses the locking spring outward. At this time, the first pawl 611 and the second pawl 621 are moved by the first cylinder 61 and the second cylinder 62 respectively. The first pawl 611 and the second pawl 621 can be brought together or moved outwards respectively. When the first pawl 611 and the second pawl 621 are brought together, the overall width of the first pawl 611 and the second pawl 621 is smaller than the size of the middle hole of the locking spring and the top hole of the car connector body. In this way, the first pawl 611 and the second pawl 621 can move from the top hole of the car connector body into the middle hole of the locking spring when they are brought together. Then, the movement is controlled... The first claw 611 and the second claw 621 move outwards, so that the abutting part 64 at the end of the first claw 611 and the second claw 621 abuts against the two sides of the locking spring and is exactly aligned with the side hole of the car connector body. When the first claw 611 and the second claw 621 move outwards, the two ends of the locking spring can move outwards at the side hole position. If the locking spring is broken, the locking spring will be squeezed out at the side hole position. If the locking spring is not broken, the first claw 611 and the second claw 621 will return to the close position after moving a distance, thus completing the detection of locking spring breakage.

[0063] At this time, in order to improve the detection efficiency of fracture, a moving plate is connected to the piston rod of the first cylinder 61. The moving plate is equipped with a first chuck 611 and a fourth chuck. Then, two independent second cylinders 62 and third cylinders are set. In this way, the four chucks are controlled by three cylinders, thereby realizing the synchronous detection of the fracture of the car connector body locking spring at two workstations, thereby improving the detection efficiency.

[0064] After the car connector body is placed on the fixed fixture 22, the assembly of each component will be inspected, resulting in some defective products. These defective products can be removed promptly or taken out at the end of the annular fixture. Therefore, in this embodiment, the fully automatic assembly machine also includes a feeding structure 7, located on the upper side of the worktable 2, for moving the car connector body from the fixed fixture 22 position on the annular track 21. The feeding structure 7 includes a horizontal cylinder 71 fixed to the upper side of the worktable 2 by a bracket. The piston rod of the horizontal cylinder 71 is connected to a vertical cylinder 72, and the piston rod of the vertical cylinder 72 is connected to a feeding cylinder 73. The feeding cylinder 73 is a finger cylinder, and the movable end of the feeding cylinder 73 is provided with a feeding gripper 74. At this time, multiple feeding structures 7 can be set at the corresponding inspection structure workstation position, or only one can be set at the end position. Of course, if it is set at the end position of the annular fixture, it can also be used for feeding qualified products.

[0065] In this embodiment, the structures used to move the car connector body and the locking spring are all finger cylinders. After the car connector body or the locking spring is fixed, it is moved to the corresponding position under the action of the horizontally set cylinder and the vertically set cylinder. Therefore, it will not be described in detail here.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
