DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall into the protective scope of the present application.

[0037] As shown in Figures 1-5 the embodiment of the present application, a hydrogen fuel cell stack inspection wire winding device is provided, which comprises a tool base plate 6, a wire harness winding module and a motor control module 8. The wire harness winding module is arranged on the tool base plate 6, and the wire harness winding module is electrically connected with the motor control module 8.

[0038] The wire harness winding module is used to drive the rubber belt to rotate to complete the winding of the inspection wire.

[0039] The wire harness winding module comprises a supporting plate 1, a fixing plate 10, a rotating mechanism, a winding disc 11, a rubber belt fixing seat 19 and a cutting mechanism 20. The supporting plate 1 is horizontally placed, and the motor control module 8 and the vertical fixing plate 10 are fixedly installed on the supporting plate 1. The rotating mechanism and the winding disc 11 are both arranged on the fixing plate 10. The rubber belt fixing seat 19 and the cutting mechanism 20 are both arranged on the winding disc 11. The cutting mechanism 20 comprises a cutting fixing block 20-1, a cutter head 20-2 and a spring 20-3. The cutting fixing block 20-1 is fixedly installed on the winding disc 11. The cutter head 20-2 has an oblique cutting surface at the front end. A cutting part is arranged at the front end of the oblique cutting surface along the direction of the oblique cutting surface. The rear end of the cutter head 20-2 is movably connected with one end of the cutting fixing block 20-1. The front end of the cutter head 20-2 is connected with the other end of the cutting fixing block 20-1 through the spring 20-3.

[0040] The fixing plate 10 has a round hole on one side and a horizontal notch to facilitate the inspection of the wire harness entering the round hole. The winding disc 11 is annular and is arranged concentrically with the round hole. The annular winding disc 11 has a notch to facilitate the inspection of the wire harness entering.

[0041] The rotating mechanism includes a rotating drive unit and a rotating support unit. The winding disk 11 is disposed on the rotating support unit, and the rotating drive unit drives the winding disk 11 to rotate.

[0042] The rotary drive unit includes a geared motor 9, a first drive pulley 23, an idler pulley 21, and a first synchronous toothed belt 22. The geared motor 9, mounted on a fixed plate, drives the first drive pulley 23 to rotate. At least two idler pulleys 21 are arranged circumferentially along one side of the outer ring of the winding disc 11. The inner surface of the first synchronous toothed belt 22 is provided with several transmission teeth, which mesh with the first drive pulley 23 and the idler pulleys 21. When the geared motor 9 rotates forward, the first drive pulley 23 rotates, thereby driving the idler pulleys 21 to rotate. The outer surface of the first synchronous toothed belt 22 is rough, and part of the rough surface of the first synchronous toothed belt 22 engages with the side of the winding disc 11 through transmission. Friction forces drive the winding disc 11 to rotate, thereby causing the tape to rotate circumferentially and wrap the tape around the inspection wire harness.

[0043] The rotating support includes at least two support guide wheels 18, which are arranged along the circumference of the other side of the outer ring of the winding disc 11. The support guide wheels 18, in conjunction with the idler wheel 21, ensure the stable rotation of the winding disc 11.

[0044] A tape holder 19 is fixedly installed on the annular winding reel 11. The tape holder 19 is located on the opposite side of the notch of the winding reel 11, and the tape used for winding and bundling the inspection wire harness is installed on the tape holder 19. A cutting mechanism 20 for cutting the tape is provided next to the tape holder 19. When the notch of the winding reel 11 is in a horizontal state, the cutting mechanism 20 is fixedly installed on the tape holder 19 at a position slightly to the right in the vertical direction.

[0045] Specifically, the position of the cutting mechanism can be determined based on the diameter of the winding harness, the initial inner and outer diameters of the tape, and the center distance.

[0046] Preferably, when the notch of the winding disc 11 is in a horizontal state, the cutting mechanism 20 is fixedly installed at a position 10° to the right in the vertical direction of the tape fixing seat 19.

[0047] The blade 20-2 is generally rectangular, and the cutting part at the front end of the blade 20-2 is a row of serrations or blades.

[0048] like Figure 4 As shown, in order to avoid cutting the tape during the tape wrapping process, the angle formed by the beveled surface of the cutter head should not be too small. The minimum angle formed by the beveled surface of the cutter head is 22.5°, and the preferred angle is 25°.

[0049] When the reduction motor 9 rotates forward, the winding disc 11 drives the circumferential movement of the adhesive tape to wind the adhesive tape on the inspection harness, at this time the adhesive tape has tension, the adhesive tape is closely attached to the oblique cutting surface at the front end of the tool bit 20-2, under the action of the tension of the adhesive tape, the tool bit 20-2 rotates counterclockwise, so that the spring 20-3 is compressed; after winding is completed, the reduction motor 9 reverses, the tension of the adhesive tape becomes smaller, the spring 20-3 in the compressed state rebounds and presses downward, so that the tool bit 20-2 rotates clockwise, the sawtooth at the front end of the oblique cutting surface of the tool bit 20-2 instantaneously contacts the adhesive tape, and the adhesive tape is cut under the action of the elastic force.

[0050] By setting the cutting mechanism on the harness winding module, the structure and position are ingeniously set, and under the premise of not adding additional control mechanism, the reduction motor driving the circumferential movement of the adhesive tape is reversed, so that the cutting mechanism can automatically cut the adhesive tape, further simplifying the structure of the hydrogen fuel cell stack inspection harness winding device, and making it small and compact.

[0051] The hydrogen fuel cell stack inspection harness winding device further comprises a sliding assembly module, which is arranged on the tool base plate 6 and is used to drive the harness winding module to reciprocate in a direction perpendicular to the fixed plate 10, and the sliding assembly module is electrically connected with the motor control module 8.

[0052] The sliding assembly module comprises a synchronous motor 7, a motor fixing seat 13, a second driving pulley 14, a driven pulley 2, a pulley fixing seat 3 and a second synchronous toothed belt 12.

[0053] The motor fixing seat 13 and the pulley fixing seat 3 are arranged on the tool base plate 6, the synchronous motor 7 is installed on the motor fixing seat 13, the synchronous motor 7 drives the second driving pulley 14 to rotate, the driven pulley 2 is installed on the pulley fixing seat 3, and the second driving pulley 14 and the driven pulley 2 are connected through the second synchronous toothed belt 12.

[0054] The contact part of the supporting plate 1 below and the second synchronous toothed belt 12 is fixedly bonded, when the second synchronous toothed belt 12 rotates, the harness winding module can reciprocate in a direction perpendicular to the fixed plate 10 along with the second synchronous toothed belt 12.

[0055] The motor control module 8 comprises a motor controller, an inverter and a display unit. The rotation direction, rotation speed and rotation time of the synchronous motor 7 and the reduction motor 9 can be set through the motor control module 8, so as to control the winding density and length of the adhesive tape of the inspection harness.

[0056] Further, in order to make the movement of the harness winding module more stable, two straight guide rails 5 are arranged on both sides of the second synchronous toothed belt 12 on the tool base plate 6, and two straight guide rail sliders 4 are correspondingly arranged below the supporting plate 1, the two straight guide rail sliders 4 are matched with the two straight guide rails 5 respectively, so as to ensure the stable movement of the harness winding module.

[0057] In order to automatically identify the required winding length of the inspection wire harness, two position sensors, i.e., a first position sensor 16 and a second position sensor 17, are arranged on the tool base plate 6 along the length direction of the linear guide rail 5. The distance between the first position sensor 16 and the second position sensor 17 is the winding length of the inspection wire harness, and the first position sensor 16 and the second position sensor 17 are electrically connected with the motor control module 8.

[0058] Further, in order to adapt to the winding length requirements of different inspection wire harnesses, the positions of the first position sensor 16 and the second position sensor 17 can be adjusted, and the installation distance of the first position sensor 16 and the second position sensor 17 can be determined according to the winding length of the inspection wire harness. By adjusting the position of the position sensor, the running distance of the synchronous motor 7 is controlled to adapt to the winding length requirements of different inspection wire harnesses.

[0059] In order to ensure that the flatness of the inspection wire harness tape winding and bundling meets the requirements, the inspection wire harness needs to be in a fixed placement state during bundling and winding, and therefore a wire harness fixing mechanism 15 can be arranged on the tool base plate 6 to fix the inspection wire harness. The wire harness fixing mechanism 15 includes a support column and a clamping part, the clamping part is arranged at the top end of the support column, the clamping part includes two clamping plates, the two clamping plates are relatively moved by screw adjustment, and when the wire harness is placed between the two clamping plates, the wire harness is clamped by adjusting the distance between the two clamping plates.

[0060] It should be noted that although in the embodiment, the clamping part is two clamping plates, the two clamping plates are relatively moved by screw adjustment, but other clamping parts with clamping function, such as openable and closable clamps, can also be used as the clamping part applied to the present application without departing from the essential content of the present application.

[0061] During work, the inspection wire harness enters the inner ring of the winding disc 11 through the gap, one end of the inspection wire harness is connected to the bipolar plate of a single battery of the stack, and the other end of the inspection wire harness is fixed on the wire harness fixing mechanism 15.

[0062] As shown in FIG. 5, the working principle of the inspection wire harness winding device of the hydrogen fuel cell stack according to the embodiment of the present application is as follows: Figure 6

[0063] ​When the hydrogen fuel cell stack inspection wire harness winding device is connected to the external power supply, the motor control module 8 can control the reduction motor 9 to rotate forward, thereby controlling the first synchronous toothed belt 22 to drive the winding disc 11 to rotate, and winding and bundling the inspection wire harness; the motor control module 8 can also control the synchronous motor 7 to rotate, cooperating with the position sensor, to drive the wire harness winding module to move a proper distance, to realize winding and bundling of a certain length of the inspection wire harness; after the inspection wire harness is bundled, the motor control module 8 can control the reduction motor 9 to rotate reversely, thereby controlling the first synchronous toothed belt 22 to drive the winding disc 11 to rotate reversely, so that the cutting mechanism 20 cuts the adhesive tape.

[0064] The motor control module 8 controls the rotating speed of the winding disc 11 and the horizontal moving speed of the wire harness winding module according to the rotating direction, rotating speed and rotating time of the synchronous motor 7 and the reduction motor 9, that is, controls the adhesive tape winding density of the inspection wire harness; by cooperating with the two position sensors, the motor control module 8 controls the horizontal moving distance of the wire harness winding module, that is, controls the adhesive tape winding length of the inspection wire harness.

[0065] The specific working method of the hydrogen fuel cell stack inspection wire harness winding device is as follows:

[0068] The positions of the first position sensor 16 and the second position sensor 17 are adjusted according to the required winding length of the inspection wire harness, so that the distance between the first position sensor 16 and the second position sensor 17 is equal to the required winding length of the inspection wire harness. Then the synchronous motor 7 is controlled to rotate, so that the wire harness winding module moves to the starting position, that is, the position when the fixed plate 10 and the first position sensor 16 are located in the same horizontal plane;

[0069] The inspection wire harness fixed on the bipolar plate of the stack is divided into multiple parts according to the number of connector pins, one part of the inspection wire harness to be wound and bundled is taken, the inspection wire harness is passed through the gap into the inner ring of the winding disc 11, the other end of the inspection wire harness is fixed on the wire harness fixing mechanism 15, and the adhesive tape is manually stuck on the inspection wire harness, so as to complete the preparation work;

[0070] The motor control module 8 first sends a command to the reduction motor 9, the reduction motor 9 starts to work, drives the first driving pulley 23 to rotate, thereby driving the adhesive tape on the winding disc 11 to move in a circle through the first synchronous toothed belt 22, and winding the adhesive tape on the wire harness;

[0071] After winding 2-3 turns, the motor control module 8 sends a command to the synchronous motor 7, the synchronous motor 7 drives the second driving pulley 14 to rotate, thereby driving the wire harness winding module to run from the first position sensor 16 to the second position sensor 17 through the second synchronous toothed belt 12;

[0072] The motor control module 8 controls the reverse rotation of the reduction motor 9, and the adhesive tape is cut off under the action of the cutting mechanism 20, the motor stops working, and the winding and bundling of the inspection wire harness are completed.

[0073] Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
