Description

Technical Field

[0001] This application relates to the field of automotive wiring harnesses, and more particularly to a cable tray sorting rack. Background Technology

[0002] As an important component of automobiles, automotive wiring harnesses are used to connect electrical components in the vehicle.

[0003] Automotive wiring harnesses typically consist of wiring harnesses with terminals and connectors. The wiring harnesses are often quite long to facilitate the connection of electrical components that are located far apart in the vehicle.

[0004] Chinese Patent No. CN217281596U discloses a power strip sorting rack, which includes a rack body, a wire harness box, an accessory box, and a wire harness fixing clip. The rack body is provided with an upper shelf and a lower shelf, and the front of the rack body is provided with a sliding groove plate, and the wire harness fixing clip is slidably snapped onto the sliding groove plate.

[0005] During assembly, select the corresponding wire harness from different wire harness boxes according to the actual wire harness requirements of the automotive wiring harness. For example, if an automotive wiring harness requires 5 types of wire harnesses, then the corresponding wire harnesses need to be taken from 5 wire harness boxes. Then, fix the wire harnesses on the wire harness fixing clips with the terminals facing upwards. Then, select connectors and other accessories from the accessory box to assemble the wire harnesses and accessories.

[0006] However, when there are too many types of wiring harnesses required for automotive wiring harnesses, operators need to reach out multiple times to retrieve the harnesses from multiple harness boxes, which is inconvenient. Furthermore, when some harness boxes are placed at a height that is relatively high for the operator, it is even more inconvenient for shorter operators to retrieve the harnesses, thus affecting assembly efficiency. Summary of the Invention

[0007] To improve assembly efficiency, this application provides a power strip sorting rack.

[0008] This application provides a power strip sorting rack, which adopts the following technical solution:

[0009] A power strip sorting rack includes a frame, on which multiple sets of transfer mechanisms and accessory boxes for placing accessories are provided. Each transfer mechanism includes a rotating frame and a drive assembly for rotating the rotating frame. The rotating frame is provided with multiple fixed rods, which are inclined and have their front ends lower than their rear ends. Each fixed rod is provided with a wire harness box, the length of which is along the length of the fixed rod. The center of the top of the wire harness box is rotatably connected to the fixed rod about its axis. The two ends of the wire harness box are respectively provided with an inlet and an outlet. The position at the lowest point of the rotating frame is designated as the picking station.

[0010] By adopting the above technical solution, and by setting up a rotating frame to move multiple wire harness boxes to the picking station in sequence, operators can pick up the wire harnesses in the wire harness boxes through the discharge port without having to reach to different places or high places multiple times, which greatly improves the picking efficiency.

[0011] Furthermore, since the wire harness box is connected to a fixed rotating mechanism, it remains balanced under the influence of gravity and the rotating frame, making it more stable and easier to handle.

[0012] Secondly, according to the matching requirements of the types of automotive wiring harnesses, multiple wiring harnesses can be placed sequentially on a continuously arranged wiring harness box. Therefore, as long as the rotation sequence of the rotating frame is followed, the corresponding wiring harnesses can be picked up in sequence, which greatly improves the accuracy of picking and facilitates subsequent assembly.

[0013] Optionally, the discharge port is located at the front end of the bottom of the wire harness box, and the frame is provided with a wire pulling assembly. The wire pulling assembly is used to clamp the wire harness and drive the wire harness to move towards the front of the frame. The wire pulling assembly is located below the front of the picking station.

[0014] By adopting the above technical solution and setting the position of the discharge port, the operator can prioritize extracting the wire harness located at the bottom of the wire harness box, while the new wire harness enters the wire harness box from the top, thus achieving the purpose of new material exiting last and old material exiting new.

[0015] Furthermore, when the operator pulls a wire harness out of the wire harness box, the wire harness is placed into the wire pulling assembly. The wire pulling assembly is activated and continuously moves the wire harness to quickly pull it out of the wire harness box. This is mainly suitable for situations where the wire harness is long and there is too much wire harness accumulation. Because when the wire harness is too long, the operator's pulling action takes too long, or the wire harness is too large, and the bottom wire harness is subjected to pressure from the top wire harness, which makes the pulling friction of the bottom wire harness extremely large and increases the difficulty of pulling it out. Therefore, the wire pulling assembly can greatly simplify the difficulty of pulling out the wire harness and improve the pulling efficiency.

[0016] Optionally, the wire drawing assembly includes two first drive motors mounted on the frame. The output shaft of the first drive motor is provided with a wire drawing roller. The wire drawing roller is located below the front side of the picking station. The circumferential surface of the wire drawing roller is covered with a sponge sleeve, and a clamping gap is formed between the sponge sleeves of two adjacent wire drawing rollers.

[0017] By adopting the above technical solution, the two sponge sleeves can elastically clamp the wire harness. Then, the first drive motor starts and the wire puller rotates to use friction to drive the wire harness forward, so as to realize the wire harness being pulled out of the wire harness box, which is convenient and quick.

[0018] Optionally, the upper end of the drawing roller is inclined toward the front side of the frame, and the circumferential surface of the drawing roller is a conical surface. The tip of the conical surface of one drawing roller is set downward, and the tip of the conical surface of the other drawing roller is set upward. The two drawing rollers are located at the same height.

[0019] By adopting the above technical solution, the frictional force applied to the wire harness by the conical surface of the drawing roller is a combination of the tangential direction and the generatrix direction. The partial components of the frictional force applied by the two drawing rollers will cancel each other out, thereby keeping the wire harness moving at a specific position on the conical surface of the drawing roller (the specific position is the vertical resultant force balance position), thereby reducing the vertical movement of the wire harness and improving the wire harness extraction stability.

[0020] Optionally, the shortest distance between the conical surfaces of the two drawing rollers gradually increases from bottom to top, and the upper end of the clamping gap is used to allow the wire harness to enter the clamping gap.

[0021] By adopting the above technical solution, the wire harness is inserted into the clamping gap from the upper end of the clamping gap. The width of the clamping gap that can be inserted varies depending on the diameter of the wire harness, so it can be adapted to clamp wire harnesses of different diameters, making it more adaptable.

[0022] Optionally, the frame is provided with an oscillation component, which is used to oscillate the wire harness box located at the picking station.

[0023] Because the wire harnesses inside the harness box are too large, the resistance to pulling out the bottom wire harness is high and it may also pull on the nearby wire harness terminals, or cause the terminals to detach or shift. By adopting the above technical solution, the accumulated wire harnesses inside the harness box are oscillated by an oscillation component to achieve a vibration liquefaction phenomenon. The friction between adjacent wire harnesses is greatly reduced, which greatly facilitates the removal of the bottom wire harness.

[0024] Optionally, the wire harness box includes a box body and a base plate. The box body has a lower opening, and the base plate is located at the lower opening of the box body. The base plate and the box body are connected by a first spring, and the base plate is made of steel plate. The oscillation assembly includes a first lifting cylinder and two oscillation motors mounted on the frame. The first lifting cylinder is located directly below the base plate. A vertically arranged second spring is fixed to the upper end of the piston rod of the lifting cylinder. Both oscillation motors are fixed to the upper ends of the second springs. The oscillation force of the two oscillation motors is in the up-down direction. A first electromagnet is fixed to both oscillation motors. The first electromagnet is used for magnetic connection with the base plate.

[0025] By adopting the above technical solution, when the wire harness box moves to the picking station, the operator first pulls out a wire harness and places it into the wire pulling assembly. The wire pulling assembly and the oscillation assembly are started simultaneously. The first lifting cylinder drives the second spring and the oscillation motor to move up close to the base plate. Then the first electromagnet is started, and the oscillation motor is connected to the base plate. The oscillation motor is then started, and the oscillation force of the oscillation motor is transmitted to the base plate to drive the stacked wire harnesses in the wire harness box to oscillate, which greatly reduces the friction between adjacent wire harnesses, thereby greatly facilitating the removal of the bottom wire harness.

[0026] Furthermore, the first lifting cylinder can adjust the height of the second spring, so that the second spring is in a state of near-unstressed condition, allowing the oscillation force of the oscillating motor to be transmitted more directly to the base plate, resulting in a stronger oscillation effect.

[0027] Furthermore, by setting up dual oscillating motors, the direction of the oscillation force can be kept vertical, thereby improving the oscillation effect.

[0028] Optionally, the base plate is densely covered with multiple ventilation holes, and the frame is equipped with an air blowing assembly for blowing air into the wire harness box. The air blowing assembly includes a second lifting cylinder, a blower, and a bellows cover tube located on the frame. The second lifting cylinder is located directly below the base plate. The lower end of the bellows cover tube is closed and fixed to the piston rod of the second lifting cylinder. The blower is used to blow air into the bellows cover tube. A second electromagnet is provided at the upper port edge of the bellows cover tube for magnetic connection with the base plate. When the upper port of the bellows cover tube is magnetically connected to the base plate, the ventilation holes communicate with the inner cavity of the bellows cover tube.

[0029] By adopting the above technical solution, when the oscillation component oscillates the wire harness box, the second lifting cylinder is activated, driving the upper end of the bellows cover tube to magnetically connect with the base plate. The ventilation hole is connected to the inner cavity of the bellows cover tube. At this time, the airflow of the blower will enter the wire harness box upward through the bellows cover tube and the ventilation hole to apply an upward force to the wire harness inside, thereby offsetting part of the weight of the wire harness and reducing the downward pressure of the wire harness on the base plate. This allows the oscillation force to better drive the wire harness to vibrate up and down, thereby improving the oscillation effect.

[0030] The bellows cover design reduces the transmission of vibrational force to the second lifting cylinder, thus minimizing the waste of vibrational force.

[0031] Optionally, the axes of each of the ventilation holes are not parallel.

[0032] By adopting the above technical solution, the air blowing direction of each ventilation hole is different, and the direction of the air blowing force on the wire harness is also different, which aggravates the irregularity of the wire harness movement during oscillation, thereby improving the oscillation liquefaction effect and reducing the resistance between adjacent wire harnesses.

[0033] Optionally, the diameter of the ventilation holes gradually increases from top to bottom.

[0034] By adopting the above technical solution, when the oscillation component drives the base plate to oscillate up and down, it will also compress and release the air inside the bellows tube. Therefore, by setting the diameter of the ventilation hole, the air in the wire harness box is less likely to enter the bellows tube, while the air inside the bellows tube is more likely to enter the wire harness box. As a result, the airflow in the bellows tube will spray a relatively high-pressure airflow into the wire harness box according to the oscillation frequency, thereby increasing the force applied to the wire harness and also assisting the oscillation to improve the oscillation effect.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. By setting up a rotating frame, multiple wire harness boxes are moved sequentially to the picking station, so that operators can pick up the wire harnesses in the wire harness boxes through the discharge port without having to reach to different places or high places multiple times, which greatly improves the picking efficiency.

[0037] 2. By setting the position of the discharge port, operators can prioritize pulling out the wire harnesses located at the bottom of the wire harness box, thus achieving the goal of new materials being discharged last and old materials being discharged new. Furthermore, the wire pulling component allows for the rapid extraction of wire harnesses from the wire harness box, thereby improving retrieval efficiency.

[0038] 3. By using an oscillation component to oscillate the stacked wire harnesses inside the wire harness box, a vibration liquefaction phenomenon is achieved, which greatly reduces the friction between adjacent wire harnesses, thereby greatly facilitating the removal of the bottom wire harness;

[0039] 4. By setting up a blower assembly to apply an upward force to the wire harness, a portion of the wire harness's weight is counteracted, thereby reducing the downward pressure of the wire harness on the base plate. This allows the oscillation force to better drive the wire harness to vibrate up and down, thus improving the oscillation effect. Attached Figure Description

[0047] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0048] Embodiment 1 of this application discloses a power strip sorting rack.

[0049] Reference Figure 1 The power strip sorting rack includes a frame 10, which is equipped with multiple sets of transfer mechanisms 20, an accessory box 104 for placing accessories, a wire harness fixing clip 101, and a slide plate 102. The accessory box 104 can be located on the front side of the frame 10 for easy access by operators.

[0050] In use, the operator removes the wire harness from the transfer mechanism 20, then fixes the wire harness to the wire harness fixing clamp 101, assembles the accessories, and then moves the wire harness fixing clamp 101 and the wire harness to the next station or to the next transfer mechanism 20 via the slide plate 102 to install another part of the wire harness, etc., until the assembly of all wire harnesses and accessories is completed.

[0051] like Figure 1 As shown, the frame 10 is provided with U-shaped dust covers 103 with upward openings on both the front and rear sides, so as to catch the excessively long part of the wire harness and reduce the dust falling to the ground at the end of the wire harness.

[0052] like Figure 2As shown, the material transfer mechanism 20 includes a rotating frame 1, a drive assembly, a wire drawing assembly 2, and an oscillation assembly 3. A vertical arm 12 is fixed to the rear side of the frame 10. A rotating shaft 13 is rotatably mounted on the upper end of the vertical arm 12. The rotating shaft 13 is inclined, and the front end of the rotating shaft 13 near the front side of the frame 10 is lower than the rear end of the rotating shaft 13. The rotating frame 1 is coaxially and fixedly connected to the rotating shaft 13. The drive assembly includes a second drive motor 11, which is mounted on the frame 10. The second drive motor 11 drives the rotating shaft 13 to rotate through belt transmission, thereby driving the rotating frame 1 to rotate.

[0053] like Figure 2 , Figure 3 As shown, multiple fixing rods 14 are fixed circumferentially on the rotating frame 1. The fixing rods 14 are parallel to the rotating shaft 13 and are evenly arranged along the circumference of the rotating frame 1. A long strip-shaped wire harness box 4 is mounted on each fixing rod 14. The length of the wire harness box 4 is along the length of the fixing rod 14. The wire harness box 4 includes a box body 41 and a base plate 42. A ring 15 is fixed at the center of the top of the box body 41. The ring 15 is rotatably fitted onto the fixing rod 14, thereby achieving a rotatable connection between the box body 41 and the fixing rod 14. 1. It has a bottom opening, and the bottom plate 42 is located at the bottom opening of the box body 41. The side of the bottom plate 42 is connected to the box body 41 through the first spring 45. The rear end of the box body 41 is provided with a feeding port 43 for the wire harness to enter the inner cavity of the wire harness box 4 for stacking. There is a gap between the bottom plate 42 and the front end of the box body 41. This gap is the discharge port 44, that is, the operator can take the wire harness from the bottom of the front end of the wire harness box 4. That is, the wire harness at the bottom is pulled out each time, so as to achieve the purpose of new material going out last and old material going out first.

[0054] The lowest position of the rotating frame 1 is set as the picking station 100, that is, the rotating frame 1 can move each wire harness box 4 to the picking station 100 in sequence, so that the operator can pick up the wire harness.

[0055] like Figure 2 , Figure 4 As shown, the wire drawing assembly 2 is located below the front side of the picking station 100. The wire drawing assembly 2 includes two first drive motors 21. The first drive motors 21 are mounted on the frame 10 and located below the front side of the picking station 100. The first drive motors 21 are arranged side by side. The output shaft of the first drive motors 21 is fixed with a wire drawing roller 22. The upper end of the wire drawing roller 22 is inclined towards the front side of the frame 10. The circumferential surface of the wire drawing roller 22 is a conical surface. The tip of the conical surface of one wire drawing roller 22 is set downward, and the tip of the conical surface of the other wire drawing roller 22 is set upward. The two wire drawing rollers 22 are at the same height, and the conical angles of the two wire drawing rollers 22 are different, so that the shortest distance between the conical surfaces of the two wire drawing rollers 22 gradually increases from bottom to top.

[0056] The conical surfaces of the drawing rollers 22 are all covered with sponge sleeves 23. A clamping gap 24 is formed between the sponge sleeves 23 of two adjacent drawing rollers 22. The upper end of the clamping gap 24 is used for the wire bundle to enter the clamping gap 24.

[0057] like Figure 5 As shown, the oscillation assembly 3 is located directly below the rotating frame 1. The oscillation assembly 3 includes a first lifting cylinder 31 and two oscillation motors 34. The first lifting cylinder 31 is fixed on the frame 10 and is located directly below the rotating frame 1. A vertically arranged second spring 32 is fixed to the upper end of the piston rod of the first lifting cylinder 31. A bearing plate 33 is fixed to the upper end of the second spring 32. Both oscillation motors 34 are mounted on the bearing plate 33. The eccentric structures of the two oscillation motors 34 rotate together upward or downward, but the eccentric structures in the horizontal direction are opposite, so that the oscillation resultant force of the two oscillation motors 34 is only upward or downward. The two oscillation motors 34 are jointly fixed with a first electromagnet 35, which is used to magnetically connect with the base plate 42.

[0058] In use, the rotating frame 1 moves one of the wire harness boxes 4 to the picking station 100. The operator first pulls out a wire harness located at the bottom of the wire harness box 4 through the discharge port 44, and puts the wire harness into the clamping gap 24 from the upper port of the clamping gap 24. The two sponge sleeves 23 can elastically clamp the wire harness. Then the first drive motor 21 starts, and the wire pulling roller 22 rotates to use friction to drive the wire harness forward, so as to realize the wire harness is pulled out from the wire harness box 4. It is convenient and quick, so as to reduce the extraction time of excessively long wire harnesses (such as wire harnesses with a length of about 3 meters).

[0059] At the same time, the first lifting cylinder 31 is activated, which drives the second spring 32 and the oscillating motor 34 to move up and closer to the base plate 42. Then the first electromagnet 35 is activated, which connects the oscillating motor 34 to the base plate 42. The oscillating motor 34 is then activated, and the oscillation force of the oscillating motor 34 is transmitted to the base plate 42 to drive the stacked wire harnesses in the wire harness box 4 to oscillate. By utilizing the vibration liquefaction phenomenon, the friction between adjacent wire harnesses is greatly reduced, thereby reducing the resistance of the pulled wire harnesses and the damage to nearby wire harnesses caused by the pulled wire harnesses.

[0060] In this way, by using the rotating frame 1, multiple wire harness boxes 4 can be moved sequentially to the picking station 100, so that the operator can pick up the wire harness in the wire harness box 4 through the discharge port 44 without having to reach to different places or high places multiple times, which greatly improves the picking efficiency.

[0061] Furthermore, in conjunction with the wire-pulling component 2 and the oscillation component 3, the difficulty of pulling out the wire harness is greatly reduced, further improving the retrieval efficiency. Secondly, according to the wire harness type and ratio requirements of the automotive wiring harness, multiple wire harnesses can be placed sequentially on the continuously arranged wire harness box 4. Therefore, as long as the rotation sequence of the rotating frame 1 is followed, the corresponding wire harnesses can be retrieved in sequence, greatly improving the retrieval accuracy and facilitating subsequent assembly.

[0062] Example 2

[0063] Example 2 adds the following settings to Example 1, such as... Figure 6 As shown, the base plate 42 is densely covered with a plurality of ventilation holes 421. The axis of each ventilation hole 421 can be perpendicular to the base plate 42, or the axes of each ventilation hole 421 can be non-parallel. In this embodiment, the axes of each ventilation hole 421 are non-parallel, and the diameter of the ventilation hole 421 gradually increases from top to bottom.

[0064] The frame 10 is equipped with an air blowing assembly. There are two air blowing assemblies, which are located on the front and rear sides below the wire harness box 4, respectively. The oscillation assembly 3 is located in the middle of the wire harness box 4 (not shown in the figure).

[0065] The air blowing assembly includes a second lifting cylinder 51, a blower 54, and a bellows cover tube 52. The second lifting cylinder 51 is located directly below the base plate 42, and the cylinder body of the second lifting cylinder 51 is mounted on the frame 10. The lower end of the bellows cover tube 52 is closed and fixed to the piston rod of the second lifting cylinder 51. The retractable direction of the bellows cover tube 52 is vertical. The air outlet of the blower 54 is connected to the lower end of the bellows cover tube 52 through a hose 55. A second electromagnet 53 is provided circumferentially at the upper port of the bellows cover tube 52. The second electromagnet 53 has a ring structure.

[0066] When the oscillation component 3 needs to oscillate the wire harness box 4, the second lifting cylinder 51 is activated, driving the bellows cover tube 52 to move upward. The second electromagnet 53 on the bellows cover tube 52 is magnetically connected to the base plate 42. At this time, the upper end of the second bellows cover tube 52 is closed, and the ventilation hole 421 is connected to the inner cavity of the bellows cover tube 52. Then the blower is activated, and the airflow of the blower 54 will enter the wire harness box 4 upward through the bellows cover tube 52 and the ventilation hole 421 to apply an upward force to the piled wire harnesses, thereby offsetting part of the weight of the wire harnesses and reducing the downward pressure of the wire harnesses on the base plate 42. This allows the oscillation force to better drive the wire harnesses to vibrate up and down, thereby improving the oscillation effect.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
