Description

Technical Field

[0001] The present invention relates to the technical field of automotive wire harnesses, and more particularly to an automatic connection device for a new energy vehicle wire harness and a terminal block. Background Art

[0002] An automotive wire harness refers to a component formed by crimping contact terminals made of copper with an automotive cable, and then molding an insulator outside or adding a metal housing, etc., and bundling the wire harnesses to form a connecting circuit. The electrical system of an automobile includes many circuit units, each circuit unit includes several wire harnesses, and the terminals of several wire harnesses are commonly inserted into the same terminal block. The wire harnesses are fixed by the pressing force between the terminals and the interfaces of the terminal block. For some circuit units, a sealant also needs to be applied at the junction of the wire harness and the terminal block.

[0003] The process of inserting several wire harnesses into the terminal block is currently mainly completed by manual operation. That is, an operator holds the terminal block with one hand and inserts the wire harness terminals into the interfaces of the terminal block in sequence with the other hand. Repeating the same connection work of wire harness terminals and terminal blocks manually for a long time is rather cumbersome and easily causes fatigue, which will affect the connection efficiency of the wire harness terminals and the terminal block. In addition, due to the uneven operation levels of the operators, it is difficult to ensure that the wire harness terminals can be inserted along the axial direction of the interface each time during the insertion process, which will also have an adverse impact on the production yield.

[0045] As a technical optimization solution of the present invention, loading racks 13 are installed on the four outer walls of the rectangular block 40. A second placement groove 29 is provided at the central position inside the loading rack 13. Limiting strip plates 31 are rotatably installed on the inner walls on both sides of the second placement groove 29. Second soft pads are installed on the outer walls of the two limiting strip plates 31 on the side close to each other. When the rectangular block 40 rotates, it can drive multiple loading racks 13 to rotate and adjust together. A fourth driving motor is preset inside the loading rack 13, and the output end of the fourth driving motor is connected to the rotating part of the limiting strip plate 31, so as to drive the limiting strip plate 31 to rotate and adjust.

[0046] As a technical optimization solution of the present invention, two third sliding grooves 30 are provided on the outer wall of one side of the loading rack 13. Third sliding blocks 32 are installed inside the two third sliding grooves 30. Fourth electric telescopic rods 37 are installed inside the two third sliding blocks 32. The telescopic ends of the two fourth electric telescopic rods 37 are jointly connected to a moving plate 33. A first dust suction head 34 and a second dust suction head 35 are respectively installed on the upper and lower outer walls and the outer wall far from the fourth electric telescopic rod 37 of the moving plate 33. Third linear motors are preset inside the two third sliding grooves 30. The two third linear motors can drive the two third sliding blocks 32 to move back and forth inside the corresponding third sliding grooves 30, and then drive multiple components such as the fourth electric telescopic rod 37 and the moving plate 33 to move together. The two first dust suction heads 34 and the second dust suction head 35 are respectively connected to the output end of a preset dust suction device outside through hoses, so that the two first dust suction heads 34 and the second dust suction head 35 can have a dust suction effect.

[0047] As a technical optimization solution of the present invention, a third groove 38 is provided on the outer wall of the moving plate 33 close to the fourth electric telescopic rod 37. A third double-headed screw 39 is rotatably installed inside the third groove 38. Cleaning plates 36 for cleaning the outer walls of the terminals of the wire harness body 6 are installed on the outer wall of the third double-headed screw 39. A driving device is preset inside the moving plate 33, and the output end of the driving device is connected to one end of the third double-headed screw 39, so as to drive the third double-headed screw 39 to rotate inside the third groove 38, and then drive the two cleaning plates 36 to move in the direction of approaching or separating from each other.

[0048] In the present invention, when the user uses the device, refer to Figure 2 and Figure 10As shown in the figure, first control the two uppermost third sliders 32 to move upward to the top inside the corresponding third chute 30, and then drive the moving plate 33 to move to the top accordingly. Then, the terminals of multiple wire harness bodies 6 that need to be connected to the terminal block body 5 can be placed in the second placement groove 29 inside the uppermost loading rack 13 by means of an external manipulator. At this time, the bottom of the terminal of the wire harness body 6 is in contact with the top of the two cleaning plates 36. The bottom of the terminal can be cleaned by means of the two approaching cleaning plates 36. Then, control the two cleaning plates 36 to move in the direction away from each other to reset, so that the terminal of the wire harness body 6 slides downward to the bottom inside the second placement groove 29. At this time, control the two third sliders 32 to drive multiple components such as the moving plate 33 to move downward to the top of the terminal of the wire harness body 6, so that the bottom of the two cleaning plates 36 abuts against the top of the terminal. By means of the movement of the two cleaning plates 36, the top of the terminal can be cleaned. When the terminals of the subsequent other wire harness bodies 6 are sequentially placed inside the second placement groove 29, the above operations can be repeated to clean the upper and lower outer walls of the terminals of the multiple wire harness bodies 6.

[0049] After placing a sufficient amount of terminals of the wire harness body 6 inside the second placement groove 29, at this time, control the externally preset dust suction device to start, so that the two first dust suction heads 34 start. As the third slider 32 continues to move up and down inside the third chute 30, it can drive the two cleaning plates 36 to clean the two side walls of the multiple terminals, and by means of the two first dust suction heads 34, dust suction treatment can be carried out on the multiple jacks provided on the outer wall of the side where the multiple terminals are connected to the terminal block body 5, avoiding problems such as poor contact or short circuit between the subsequent wire harness body 6 and the terminal block body 5 caused by dust and other sundries on the terminal surface and inside the jacks, which is convenient for improving the connection stability of the wire harness body 6 and the terminal block body 5 and the reliability of subsequent use.

[0050] At the same time, after placing the terminals of multiple wiring harness bodies 6 inside the second placement groove 29 and cleaning the terminal surfaces with the help of the cleaning plate 36 and the first dust suction head 34, the two third sliders 32 can be controlled to move in turn inside the corresponding third slide groove 30 to the terminal position close to each wiring harness body 6, and then the two sides of the terminal are clamped and fixed with the help of two cleaning plates 36 moving in the direction of approaching each other, and then the telescopic ends of the two fourth electric telescopic rods 37 are controlled to extend together, driving the moving plate 33 and the two cleaning plates 36 to move in the direction away from the loading rack 13, and the wiring harness body 6 is pulled by the two cleaning plates 36 to clamp the terminals. Since the other end of the wiring harness body 6 is limited by two limiting strips 31 and the second soft pad, the two second soft pads are in flexible contact with the other end of the wiring harness body 6. In the process of pulling the wiring harness body 6, the cable and terminal connection quality of the wiring harness body 6 itself can be tested to avoid defects in the wiring harness body 6 itself, which may cause problems in the subsequent connection with the terminal row body 5 for use.

[0051] If there is no problem with the tested wiring harness body 6, the two third sliders 32 can be used to drive the movable plate 33 and the cleaning plate 36 to test other wiring harness bodies 6. If there is a problem with the tested wiring harness body 6, the two limiting strips 31 can be controlled to rotate outward from the inside of the second placement slot 29, and the two limiting strips 31 no longer limit the cable part of the wiring harness body 6. After the terminals of the wiring harness body 6 with problems are clamped with the help of the two cleaning plates 36, the two fourth electric telescopic rods 37 are controlled to extend their telescopic ends, driving the cleaning plates 36 and the terminals of the clamped wiring harness body 6 to move together in a direction away from the loading rack 13, and the wiring harness body 6 with problems is automatically removed from the inside of the second placement slot 29 to avoid affecting the subsequent connection with the terminal block body 5.

[0052] Then the terminal block body 5 can be placed in the top center position of the fixing block 4, and the first double-headed screw 17 can be controlled to rotate, driving the two clamping plates 18 to clamp and fix the outer walls on both sides of the terminal block body 5, waiting for the subsequent terminals of multiple wiring harness bodies 6 to be plugged and connected with the multiple slots on the outer wall of one side of the terminal block body 5.

[0053] After ensuring that there are no problems with the multiple harness bodies 6 temporarily stored in the second placement slot 29, the rectangular block 40 can be controlled to drive the loading rack 13 to rotate 90 degrees toward the direction close to the top plate 3, so that the top loading rack 13 rotates to a position flush with the moving rack 7, such as Figure 2As shown, the opening position of the second placement groove 29 abuts and corresponds to the opening position of the first placement groove 23 inside the moving frame 7. At this time, by controlling the two third sliders 32 to drive components such as the moving plate 33 to move to the end away from the bottom plate 1, after clamping and fixing the terminals of one of the wire harness bodies 6 at the leftmost end with the two cleaning plates 36, by controlling the two third sliders 32 to drive components such as the moving plate 33 to move towards the right end, the terminals of all the wire harness bodies 6 inside the second placement groove 29 can be smoothly pushed into the first placement groove 23, so that multiple wire harness bodies 6 can be automatically fed into the moving frame 7, achieving the effect of automatic feeding.

[0054] After transferring multiple wire harness bodies 6 inside the loading rack 13 to the inside of the moving frame 7, the second slider 28 can be controlled to move inside the second sliding groove 14, and then drive multiple components such as the vertical rod 10 and the loading rack 13 to move together, so that the loading rack 13 at the right end at this time moves to a position close to the terminal block body 5. By controlling the telescopic ends of the two electric push rods 8 to contract, the moving seat 9 is driven to move towards the direction close to the bottom plate 1, so that the loading rack 13 at the right end moves to a position between the moving frame 7 and the terminal block body 5. At this time, by controlling the externally preset dust suction device to start, the second dust suction head 35 can generate suction. As the two third sliders 32 move inside the corresponding third sliding grooves 30, the moving plate 33 and the second dust suction head 35 are driven to perform dust suction treatment on the multiple slots inside the terminal block body 5, avoiding dust and other sundries adhering to the inside of the slots and affecting the subsequent connection with the terminals of multiple wire harness bodies 6, so as to further improve the stability and reliability of the connection and use of multiple wire harness bodies 6 and the terminal block body 5, and reduce the occurrence of poor contact and short circuit conditions.

[0055] The rectangular block 40 can be controlled to drive the loading rack 13 to continue to rotate downward by 90 degrees, so that the loading rack 13 at the left end rotates to the uppermost position. Repeating the above steps of placing the terminals of multiple wire harness bodies 6 inside the second placement groove 29 can achieve the effect of continuous feeding, facilitating the improvement of the connection efficiency between the wire harness body 6 and the terminal block body 5.

[0056] After the terminals of multiple wire harness bodies 6 enter the inside of the first placement groove 23, two fourth sliders 44 can be controlled to move downward inside the corresponding fourth sliding grooves 42, thereby driving the moving strip plate 41 and multiple mounting blocks 22 and multiple groups of adjusting plates 24 at its bottom to move downward and pass through the through slots 43, so that multiple groups of adjusting plates 24 are respectively located between the terminals of two adjacent wire harness bodies 6, and drive the movable block 25 to block the opening of the first placement groove 23. Then, the second double-headed screw 27 inside the multiple second grooves 26 is controlled to rotate, driving two corresponding adjusting plates 24 to move away from each other, and pushing the outer walls of the adjacent sides of the terminals of multiple wire harness bodies 6 inside the first placement groove 23, so that the distances between the terminals of multiple wire harness bodies 6 inside the first placement groove 23 are kept the same, ensuring that the terminals of multiple wire harness bodies 6 can correspond to the slots of the terminal block body 5 one by one, which brings convenience for the subsequent synchronous insertion of the terminals of multiple wire harness bodies 6 into the slots.

[0057] Then, two first sliders 19 can be controlled to move in the corresponding first sliding grooves 15 towards the direction close to the fixed block 4, thereby driving the moving frame 7 and the terminals of multiple wire harness bodies 6 inside it to be automatically inserted into the slots of the terminal block body 5, realizing the rapid automatic connection of the wire harness body 6 and the terminal block body 5 and improving the connection efficiency of the wire harness body 6 and the terminal block body 5; moreover, if the slots on the outer wall of the terminal block body 5 are multi-row, after the feeding frame 13 conveys multiple wire harness bodies 6 inside the second placement groove 29 to the inside of the first placement groove 23 of the moving frame 7, by controlling the telescopic ends of two first electric telescopic rods 20 to extend upward, the moving frame 7 is driven to correspond to other slot positions of the terminal block body 5, and the telescopic ends of two third electric telescopic rods 11 are controlled to adaptively extend upward as the telescopic ends of two first electric telescopic rods 20 extend, which is convenient for subsequent conveying of the wire harness bodies 6 inside the feeding frame 13 to the inside of the moving frame 7, so that the automatic connection mechanism can also be applicable to the connection of more wire harness bodies 6 and terminal block bodies 5, further improving the applicability of the device.
