[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0030] It should also be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0032] like Figures 1 to 5 As shown, an automatic belt winding station device includes a base 1 and a vehicle guide assembly 2, a vehicle clamping assembly 3, a vehicle moving assembly 4, an I-beam wheel rotating assembly 5, a magnetic powder brake assembly 6, and a vehicle fixing assembly 7 disposed on the base 1.
[0033] An inlet end 11 is provided on the base 1 of the device, and the vehicle guide assembly 2 is provided at the inlet end 11. The vehicle clamping assembly 3 and the vehicle moving assembly 4 are both arranged along the straight line L1 and are respectively installed on the left and right sides of the inlet end 11. The belt harness tooling car is moved to a specific position by the vehicle clamping assembly 3 and the vehicle moving assembly 4, and then fixed by the vehicle fixing assembly 7. The I-beam wheel rotating assembly 5 and the magnetic powder brake assembly 6 control the curling and tension of the belt harness on the vehicle.
[0034] This device enables automatic positioning of belt-driven tooling vehicles for entry, exit, and winding operations, significantly reducing the labor intensity of employees pushing and pulling tooling vehicles, minimizing employee actions while operating equipment, and improving production efficiency.
[0035] like Figure 1As shown, the vehicle guiding assembly 2 includes guide supports 21 and guide rods 22. Two sets of guide supports 21 are respectively located on the left and right sides of the inlet end 11 of the base 1. Two sets of guide rods 22 are symmetrically installed on the two guide supports 21 along the straight line L1. The guide rods 22 have a flared opening at the point away from the inlet, allowing the belt-driven tooling vehicle to be pushed into the device more easily.
[0036] To ensure greater precision in moving and securing the vehicle, the vehicle clamping assembly 3 and the vehicle moving assembly 4 are equipped with photoelectric sensors 23 on the vehicle guide assembly 2. Two sets of photoelectric sensors 23 are positioned opposite each other on the two guide rods 22. When the belt-loaded tooling vehicle is pushed into the device from the inlet end 11, the vehicle clamping assembly 3 and the vehicle moving assembly 4 begin to operate when the front end of the vehicle passes the photoelectric sensor 23, and stop operating when the rear end passes the photoelectric sensor 23.
[0037] The aforementioned vehicle clamping assembly 3 and vehicle moving assembly 4 are specifically as follows: Figures 1 to 3 As shown.
[0038] The vehicle clamping assembly 3 includes a clamping housing 31 and a clamping cylinder 32, a linkage mechanism, and a driven wheel 34 mounted on the clamping housing 31. The clamping housing 31 is arranged along the straight line L1 and is located on the left side of the inlet end 11 of the base 1. The clamping cylinder 32 is hinged to the clamping housing 31. The output end of the clamping cylinder 32 is driven to one end of the linkage mechanism, and the other end of the linkage mechanism is driven to the driven wheel 34. The axial movement of the clamping cylinder 32 drives the linkage mechanism and drives the driven wheel 34 to move toward / away from the vehicle moving assembly 4.
[0039] The linkage mechanism includes a rotating part 332, which includes a rotating bearing 334 mounted on the clamping housing 31, a rotating shaft 335 rotatably connected to the rotating bearing 334, and an output transmission member 336 fixed to the top of the rotating shaft 335. The driven wheel 34 is mounted at the end of the output transmission member 336 away from the rotating shaft 335.
[0040] Since the aforementioned linkage mechanism can be either a fixed or non-fixed structure, when it is a non-fixed structure, the overall stability of the vehicle clamping assembly 3 cannot be well guaranteed. To ensure the stability of the overall structure, the linkage mechanism is set to a fixed structure (described later). However, a fixed structure requires transmission through the clamping cylinder 32. When the clamping cylinder 32 is also a fixed structure, the device cannot operate normally. Therefore, the clamping cylinder 32 is set to have its tail end hinged to the clamping housing 31, so that the overall structure can ensure both stability and normal operation.
[0041] like Figures 1 to 2 As shown, the linkage mechanism also includes a transmission plate 331 fixedly connected to the rotating shaft 335, and the transmission plate 331 is connected to the output end of the clamping cylinder 32; by driving the clamping cylinder 32, it drives the transmission plate 331 and the rotating part 332 to rotate.
[0042] The rotating part 332 has several forms:
[0043] Example 1: There are several rotating parts 332, and each rotating part 332 is provided with a transmission plate 331. All transmission plates 331 are connected by a first connecting rod. One end of the first connecting rod is hinged to the output end of the clamping cylinder 32.
[0044] Example 2: There are several rotating parts 332, one of which is the main rotating part 332 and the rest are secondary rotating parts 332; the main rotating part 332 is provided with a transmission plate 331, which is hinged to the output end of the clamping cylinder 32; all rotating parts 332 are connected together by a connecting part 333.
[0045] Example 3: There are a total of several rotating parts 332, which are divided into several equal parts. Each part has a main rotating part 332 and the rest of the secondary rotating parts 332. Each main rotating part 332 is provided with a transmission plate 331. The transmission plates 331 of all the main rotating parts 332 are connected by a first connecting rod. Then, a connecting part 333 is provided to connect the main rotating part 332 and the secondary rotating parts 332 in each part.
[0046] Specifically, the connecting part 333 includes a connecting plate 337 fixedly connected to the rotating shaft and a second connecting rod 338 for connecting multiple connecting plates 337.
[0047] like Figure 3 As shown, the vehicle moving assembly 4 includes a moving housing 41 and a moving motor 42, a moving chain 43, a moving gear 44, and a drive wheel 45 mounted on the moving housing 41. The moving housing 41 is arranged along the straight line L1 and is located on the right side of the inlet end 11 of the base 1. Several vertically arranged moving rotating shafts 46 are mounted on the moving housing 41. Moving gears 44 are mounted on the moving rotating shafts 46 and the output shafts of the moving motor 42, and are connected by the moving chain 43. The drive wheel 45 is mounted on the top of the moving rotating shaft 46 and is driven by the moving motor 42.
[0048] When the belt-mounted tooling car passes the photoelectric sensor switch 23, it simultaneously drives the clamping cylinder 32 and the moving motor 42, so that the two components operate at the same time.
[0049] Specifically, the output end of the clamping cylinder 32 begins axial movement, driving the transmission plate 331 to move. Since the transmission plate 331 is fixedly connected to the rotating shaft 335, during the aforementioned movement, the transmission plate 331 will cause the rotating shaft 335 to move in a circular motion (the direction of the circular motion is related to the axial movement direction of the output end of the clamping cylinder 32). When the rotating shaft 335 rotates, it will also drive the output transmission component 336 to rotate, causing the driven wheel 34 to move towards the belt harness fixture. After the two come into contact, the belt harness fixture continues to be pushed, causing its other side to abut against the driving wheel 45 of the vehicle moving assembly 4. Under the action of other components of the vehicle moving assembly 4, the driving wheel 45 drives the belt harness fixture towards the vehicle fixing assembly 7 inside the device for active transport. This structure can reduce the number of steps for workers and better ensure the accuracy and precision of the operation.
[0050] like Figures 3 to 4 As shown, the I-beam wheel rotating assembly 5 includes a rotating support base 51, a rotating connecting base 52, a rotating cylinder 53, a rotating slide rail 54, a rotating connecting disc 55, and a rotating motor 56.
[0051] A rotating support base 51 is installed on the top of the movable housing 41. A rotating slide rail 54 is located on the top of the rotating support base 51 along the straight line L2. A rotating connecting base 52 is slidably connected to the rotating slide rail 54. A rotating motor 56 is installed on the rotating connecting base 52 and a rotating connecting disc 55 is installed on the output shaft. A rotating cylinder 53 is fixedly connected to the rotating support base 51 and its output end is fixedly connected to the rotating connecting base 52.
[0052] After the belt harness carriage has moved, the I-beam rotating assembly 5 will connect with the I-beam assembly for collecting the belt harness on the carriage. When it is necessary to collect the belt harness, rotating the connecting disc 55 will drive the I-beam to rotate together, making it easier to collect the belt harness material.
[0053] The magnetic powder brake assembly 6 includes a brake support 61, a brake connector 62, a brake cylinder 63, a brake slide rail 64, a brake connecting disc 65, and a magnetic powder brake component 66. The brake support 61 is mounted on the top of the movable housing 41. The brake connector 62 is connected to the brake support 61 via the brake slide rail 64, which is located on the brake support 61 along the straight line L2. The brake cylinder 63 is fixedly connected to the brake support 61, and its output end is connected to the brake connector 62. A brake connecting shaft, which is located along the straight line L2, is mounted on the brake connector 62. The brake connecting disc 65 is mounted on the left end of the brake connecting shaft, and the magnetic powder brake component 66 is mounted on the right end of the brake connecting shaft.
[0054] This component controls the tension of the lining used to collect the belt on the belt harness tooling vehicle.
[0055] like Figure 1 and Figure 5 As shown, in order to ensure the accurate and stable positioning of the belt harness tooling vehicle, the device also includes a vehicle fixing assembly 7, which includes a fixing support plate 71, a first fixing module 72, and a second fixing module 73. The two ends of the fixing support plate 71 are respectively fixedly connected to the clamping housing 31 and the end of the moving housing 41 away from the inlet end 11. The first fixing module 72 is located at the top center of the fixing support plate 71. Two sets of the second fixing module 73 are provided and are respectively installed on the fixing support plate 71 and located on both sides of the first fixing module 72. Through the cooperation of the first fixing module 72 and the second fixing module 73, the belt harness tooling vehicle is fixed in a specific position.
[0056] Specifically, the first fixing module 72 includes a fixing guide rod 721, a fixing connecting block 722, a fixing cylinder 723, and a fixing hook 724. The fixing guide rod 721 is arranged on the top of the fixing support plate 71 along the straight line L1. The fixing guide rod 721 is provided with a fixing sliding groove 725. The fixing connecting block 722 is slidably connected to the fixing sliding groove 725. The fixing cylinder 723 is fixedly connected to the fixing guide rod 721 and its output end is fixedly connected to the fixing connecting block 722. One end of the fixing hook 724 is provided with a hook and this end faces the inlet end 11. The other end is fixedly connected to the fixing connecting block 722.
[0057] The second fixing module 73 includes a rigid fixing block 731, a rigid fixing plate 732, a rigid fixing shaft 733, and a rigid abutment block 734. The rigid fixing block 731 is disposed on the top surface of the fixing support plate 71. The rigid fixing plate 732 is fixedly connected to the side of the rigid fixing block 731 near the inlet end 11, and the top of the rigid fixing plate 732 is higher than the rigid fixing block 731. The rigid fixing shaft 733 passes through and is fixedly connected to the top of the rigid fixing plate 732. The rigid abutment block 734 is fixedly connected to the end of the rigid fixing shaft 733 near the inlet end 11.
[0058] When the belt harness fixture needs to be secured, it abuts against the vehicle fixing component 7 of the device under the continuous movement of the vehicle clamping assembly 3 and the vehicle moving assembly 4. At this time, the fixing cylinder 723 pushes the fixing connecting block 722 to move, and the fixing connecting block 722 drives the fixing hook 724 to move towards the inlet end 11. Under continuous movement, the end of the belt harness fixture first abuts against the hard abutment block 734 to stop its movement (the vehicle clamping assembly 3 and the vehicle moving assembly 4 no longer operate). At the same time, the fixing cylinder 723 drives the output end to retract, and the fixing hook 724 retracts to hook the belt harness fixture. The belt harness fixture achieves stable fixation of the three-point fixing structure under the action of the two second fixing modules 73 and the first fixing module 72.
[0059] When it is necessary to remove the belt harness fixture, simply activate the fixing cylinder 723 to release the vehicle fixing component 7 from its fixation on the belt harness fixture. At the same time, the vehicle moving component 4 drives the drive wheel 45 in the opposite direction, causing the belt harness fixture to move toward the inlet end 11 until the entire belt harness fixture is pushed out of the entire device. After the movement is completed, all components of the entire device are reset.
[0060] To better ensure the actual operation of the entire device, motor reducers are installed on both the moving motor 42 and the rotating motor 56. By setting up the reducer motor, it is possible to better ensure that the motor speed is not too fast.
[0061] Both the driving wheel 45 and the driven wheel 34 of the device are made of polyurethane material, which makes the device more stable when moving and fixing the belt harness tooling car, and also reduces wear on the belt harness tooling car.

Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
