Description

Technical Field

[0001] The invention relates to the technical field of automobile wiring harness terminal processing and feeding, in particular to an automatic feeding device for automobile high-voltage wiring harness components. Background Art

[0002] The automotive high-voltage wire harness assembly is the core component of the high-voltage system of new energy vehicles. It is mainly used for power transmission and signal shielding. Its design and selection directly affect the performance, safety and reliability of the vehicle. The high-voltage wire harness assembly is mainly composed of connectors, terminals, wires, coverings (such as insulation layers, shielding layers, sheath layers), etc. During processing, in order to reduce the workload of personnel, personnel usually place a large number of automotive high-voltage wire harnesses on a feeding device to transport them to a designated location for the next process.

[0003] For example, an existing patent (publication number: CN220810744U) discloses an automatic feeding device for wire harness bundling, which realizes automatic conveying of material boxes through the setting of servo motors, driving wheels, driven wheels, conveyor belts and rubber pads, and continuously conveys the material boxes to nearby workstations, thereby improving work efficiency.

[0004] However, the automatic feeding device for wire harness bundling designed above still has some disadvantages in actual use: although the automatic feeding device for wire harness bundling can use the box body to centrally transport a large number of wire harnesses, due to the high height of the box body, it is extremely inconvenient for personnel to take the wire harness components or terminals located deep in the box body, and usually they need to bend over to do so.

[0005] Therefore, we designed an automatic feeding device for automotive high-voltage wire harness components to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide an automatic feeding device for automotive high-voltage wire harness assemblies. By taking out the wire harness terminals from the feeding hopper, the support box will slide upward due to the reduction of gravity, thereby ensuring that the wire harness terminals are always located at the top of the feeding hopper, making it convenient for personnel to take them out without bending over to take them out, thereby improving the feeding effect and solving the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the present invention provides an automatic feeding device for automotive high-voltage wire harness assemblies, comprising a feed frame and a conveyor arranged on the top of the feed frame, the conveyor is provided with a feed hopper, a support box is slidably arranged in the feed hopper, two first sliders are symmetrically slidably arranged on the bottom wall of the feed hopper, two second sliders are symmetrically slidably arranged on the bottom of the support box, a rotating part is rotatably arranged between the first slider and the second slider, two limit members are symmetrically arranged at the bottom of the support box, and a reset spring is fixedly installed between the limit member and the second slider.

Since the support box is against the inner wall of the feed hopper, it is inevitable that there will be a problem of unsmooth sliding due to excessive friction. At this time, the driving member is turned on to drive the storage member to rotate, so that the sliding member slides in the slide groove under the influence of centrifugal force and compresses the support spring, so that the sliding member releases the closure of the oil injection channel, thereby facilitating the lubricating liquid in the storage cavity to be thrown onto the inner wall of the feed hopper through the oil injection channel, thereby achieving the effect of lubricating the support box and ensuring smooth sliding of the support box in the feed hopper.

[0014] Furthermore, a telescopic rod is fixedly installed in the slide groove, and the telescopic end of the telescopic rod is fixedly connected to one side of the slide, so that the slide can only slide along the direction of the telescopic end of the telescopic rod, avoiding the problem of movement tilt of the slide.

[0015] Furthermore, an annular groove is provided at the top of one of the sliding sheets, and two guide members are symmetrically slidably arranged in the annular groove. The top of the guide member is fixedly connected to the bottom of the storage member.

[0018] Compared with the prior art, the beneficial effect of the present invention is that by turning on the motor, the storage part can be rotated, so that the slide is affected by the centrifugal force to slide in the slide groove and compress the support spring, so that the slide releases the closure of the oil injection channel, thereby facilitating the lubricating liquid in the storage chamber to be thrown onto the inner wall of the feed hopper through the oil injection channel, thereby achieving the effect of lubricating the support box, ensuring that the support box slides smoothly in the feed hopper, and avoiding the problem of uneven sliding of the support box due to the large friction between the support box and the feed hopper.

The two ends of the rotating member 6 are rotatably sleeved on the first pin shaft and the second pin shaft respectively.

[0026] In specific implementation, during processing, personnel take out the wiring harness terminal from the feed hopper 2. At this time, the support box 3 will slide upward due to the reduction of gravity, thereby ensuring that the wiring harness terminal is always located at the top of the feed hopper 2, which is convenient for personnel to take out without bending over to take it out, thereby improving the feeding effect.

[0027] The top of the feeding frame 1 is provided with a mounting groove 27, and the conveyor includes two feeding rollers 28, which are symmetrically mounted in the mounting groove 27, and the feeding rollers 28 are tightened with a belt 29. A motor 30 is provided on one side of the feeding frame 1, and the driving shaft of the motor 30 is transmission-connected with one end of one of the feeding rollers 28, and the support box 3 is fixedly mounted on the outer surface of the belt 29. On the basis of the above implementation, a large number of automotive wiring harness terminal assemblies are placed on the support box 3 in the feeding hopper 2. At this time, the support box 3 is pressed downward in the feeding hopper 2 due to the gravity of the wiring harness. In this process, the rotating member 6 drives the two second sliders 5 and the first slider 4 away from each other along the direction set by the limit rod 10 and the guide rod 9, and then the motor 30 is turned on to rotate the feeding rollers 28, so that the belt 29 moves, which is convenient for automatically feeding the wiring harness terminal assemblies in the feeding hopper 2.

[0028] See also Figure 1-6 The two rotating members 6 are arranged to abut against each other and cross each other, and a limit axis 13 is inserted at the intersection of the two rotating members 6. The two rotating members 6 abut against each other to increase the supporting force, thereby increasing the stability during rotation.

[0029] See also Figure 1-6The support box 3 includes two sliding plates 31, a spacing is left between the two sliding plates 31 and a through hole 14 is provided, the limit member 7 is fixedly installed at the bottom of one of the sliding plates 31, a driving member is provided at the bottom center of the other sliding plate 31, a storage member 15 is provided on the driving member, a storage chamber 16, a slide groove 17 and an oil injection passage 18 are respectively provided inside and on the side of the storage member 15, the storage chamber 16, the slide groove 17 and the oil injection passage 18 are connected, the storage chamber 16 stores lubricating fluid, a support spring 19 is fixedly installed in the slide groove 17, a sliding member 20 is provided on one side of the support spring 19, the sliding member 20 is slidably arranged in the slide groove 17, a piston 21 is provided on one side of the sliding member 20, and the piston 21 is against the inner wall of the slide groove 17, the driving member includes a motor 22, the motor 22 is fixedly installed at the bottom of one of the sliding plates 31, a rotating shaft 23 is fixedly installed at the center of the top of the storage member 15, and the driving shaft of the motor 22 is transmission-connected to one end of the rotating shaft 23.

[0030] During the specific implementation, based on the above implementation, since the support box 3 and the inner wall of the feed hopper 2 are against each other, it is inevitable that there will be a problem of excessive friction resulting in unsmooth sliding. At this time, the motor 22 is turned on, so that the driving shaft of the motor 22 drives the rotating shaft 23 and the storage member 15 to rotate, so that the slide 20 is affected by the centrifugal force and slides in the slide groove 17 and compresses the support spring 19, so that the slide 20 releases the closure of the oil injection channel 18, thereby facilitating the lubricating liquid in the storage chamber 16 to be thrown onto the inner wall of the feed hopper 2 through the oil injection channel 18, thereby achieving the effect of lubricating the support box 3 and ensuring that the support box 3 slides smoothly in the feed hopper 2.

[0031] See also Figure 1-6 A telescopic rod 24 is fixedly installed in the slide groove 17, and the telescopic end of the telescopic rod 24 is fixedly connected to one side of the slide 20. The slide 20 can only slide along the direction of the telescopic end of the telescopic rod 24, avoiding the problem of movement tilt of the slide 20.

[0032] See also Figure 1-6 A circular groove 25 is formed at the top of one of the sliding sheets 31, and two guide members 26 are symmetrically slidably arranged in the circular groove 25, and the top of the guide member 26 is fixedly connected to the bottom of the storage member 15. When the storage member 15 rotates, the guide member 26 can be driven to slide in the circular groove 25, and the storage member 15 can be supported, thereby improving the stability of the storage member 15 when rotating.

[0033] Working principle: Before use, it is necessary to connect all the electrical appliances involved in the automatic feeding device of the automotive high-voltage wire harness assembly to an external power supply, or install a battery pack on the feeding rack 1 in an area that does not interfere with other components, and then connect the battery pack to the electrical appliances through lines to power the electrical appliances, thereby ensuring the normal operation of the electrical appliances. Since connecting an external power supply to the electrical appliances or setting up a battery pack to power the appliances belongs to the prior art and is not a problem to be solved in the background technology of this specification, it will not be explained in detail.

[0034] When in use, first place a large number of automotive wiring harness terminal assemblies on the support box 3 in the feed hopper 2. At this time, the support box 3 is pressed downward in the feed hopper 2 due to the gravity of the wiring harness. During this process, the rotating member 6 will drive the two second sliders 5 and the first slider 4 to move away from each other along the direction set by the limit rod 10 and the guide rod 9. Then turn on the motor 30 to rotate the feed roller 28 and move the belt 29 to facilitate the automatic feeding of the wiring harness terminal assemblies in the feed hopper 2. During processing, personnel take out the wiring harness terminals from the feed hopper 2. At this time, the support box 3 will slide upward due to the reduction of gravity, thereby ensuring that the wiring harness terminals are always located at the top of the feed hopper 2, which is convenient for personnel to take and there is no need for personnel to bend down to take them out, thereby improving the feeding effect.

[0035] Since the support box 3 is against the inner wall of the feed hopper 2, it is inevitable that there will be excessive friction resulting in unsmooth sliding. At this time, the motor 22 is turned on, so that the driving shaft of the motor 22 drives the rotating shaft 23 and the storage member 15 to rotate, so that the slide 20 is affected by the centrifugal force and slides in the slide groove 17 and compresses the support spring 19, so that the slide 20 releases the closure of the oil injection channel 18, thereby facilitating the lubricating liquid in the storage chamber 16 to be thrown around the inner wall of the feed hopper 2 through the oil injection channel 18, thereby achieving the effect of lubricating the support box 3 and ensuring that the support box 3 slides smoothly in the feed hopper 2.

[0036] In addition, by providing the telescopic rod 24 , the slide 20 can only slide along the direction of the telescopic end of the telescopic rod 24 , thereby avoiding the problem of the slide 20 tilting during movement.
