[0030] The following is combined with Figure 1-2 The utility model is further described.

[0031] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0032] Reference Figure 1 and Figure 2The utility model provides a coating machine winding and unwinding turret mechanism, which can be applied to the winding and unwinding operation of a large coil 8 with a heavy weight or an extra-long specification. The coating machine winding and unwinding turret mechanism includes a mounting frame 1, a turning frame 2, and an air expansion chuck assembly 3, wherein the air expansion chuck assembly 3 is slidably arranged on the turning frame 2 to tighten and fix the coil 8, the turning frame 2 is rotatably arranged on the mounting frame 1 to switch between at least two target stations, and the mounting frame 1 is used to support the entire structure. The mounting frame 1 is connected to a turning drive unit, and the turning drive unit is used to drive the turning frame 2 to turn over. Specifically, the turning drive unit includes a driving assembly 4 and a turning assembly 5, and the turning assembly 5 is symmetrically arranged on both sides of the turning frame 2. The driving assembly 4 simultaneously drives the turning assemblies 5 located on both sides of the turning frame 2 to work, driving the turning frame 2 to turn over. The turning assemblies 5 located on both sides of the turning frame 2 are driven by the same driving source, ensuring that the two groups of turning assemblies 5 respond to and drive the turning frame 2 to turn over at the same time. Compared with the solution in which the two sides of the turning frame 2 are driven by different driving sources, the turning synchronization and turning reliability are higher.

[0033] The mounting frame 1 is the base of the entire structure, which serves to hold various components and provide a certain rotation space for the flip frame 2. In this embodiment, the mounting frame 1 includes a bottom plate 12 and a side plate 11. The two side plates 11 are symmetrically erected on the opposite side ends of the bottom plate 12, and the flip frame 2 is rotatably arranged on the side plates 11 on both sides. In other embodiments, the mounting frame 1 can also be other structural forms, such as a gantry type, a frame type, a box type, etc. This application does not limit the specific structure of the mounting frame 1, as long as it can play the above role. The mounting frame 1 and the flip frame 2 can be made of materials with greater structural strength and structural rigidity, such as metal alloy materials such as ferroalloys. The mounting frame 1 and the flip frame 2 have great structural strength and rigidity, and can effectively support the large coil 8 to ensure the stability of flipping.

[0034] The flip assembly 5 includes a rotary reducer 51, a bearing seat 6 is fixedly connected to the mounting frame 1, and a rotating spindle 61 is rotatably connected to the bearing seat 6. Specifically, the rotating spindle 61 is rotatably arranged on the bearing seat 6 around its own axial direction, and one end of the rotating spindle 61 close to the bearing seat 6 is fixedly connected to the output end of the rotary reducer 51, and one end of the rotating spindle 61 away from the rotary reducer 51 is fixedly connected to the flip frame 2, and the center lines of the rotating spindles 61 located on both sides of the flip frame 2 are located on the same straight line. In this embodiment, the flip frame 2 is a rectangular frame structure, and the two rotating spindles 61 are respectively fixedly arranged at the midpoints of the two short sides of the flip frame 2, that is, the axes of the two rotating spindles 61 are located on the same straight line with the center lines of the short sides of the flip frame 2. When the rotating spindle 61 rotates, it drives the flip frame 2 to flip to switch to different target workstations. Such a setting is conducive to ensuring the stability and reliability of the flipping of the flip frame 2. The rotary reducer 51 is a worm gear transmission, which has the characteristic of reverse self-locking and can realize reverse self-locking, that is, the worm can only drive the worm wheel, but the worm wheel cannot drive the worm to move. The rotary reducer 51 is used to drive the turning frame 2 to turn over, and the turning frame 2 is locked and positioned after the turning is completed without rotating, which is conducive to improving the stability of the turning switching target station and the safety factor of the operation.

[0035] Furthermore, the rotating main shaft 61 can be made of a material with high structural strength and rigidity, such as a metal alloy material. The rotating main shaft 61 has high strength and can effectively support the flip frame 2 to ensure the stability and safety of flipping. The rotating main shaft 61 is installed on the mounting frame 1 through the bearing seat 6. The bearing can make the rotating main shaft 61 rotate more smoothly, which is conducive to the stable and smooth flipping of the flip frame 2.

[0036] Reference Figure 1 and Figure 2 The driving assembly 4 includes a servo motor 41 and a first commutator 42. The servo motor 41 and the first commutator 42 are fixedly arranged on the base plate 12, and the input end of the first commutator 42 is connected to the output end of the servo motor 41. The transmission shaft 43 is symmetrically connected to both sides of the first commutator 42. The flip assembly 5 also includes a second commutator 53. The second commutator 53 is fixedly installed on the mounting frame 1. One end of the transmission shaft 43 away from the first commutator 42 is connected to the input end of the second commutator 53, and the output end of the second commutator 53 is connected to the rotary reducer 51.

[0037] Specifically, the transmission shafts 43 on both sides are coaxially arranged, and the output shaft of the servo motor 41 is perpendicular to the axes of the transmission shafts 43 on both sides. The first commutator 42 transmits the power output by the servo motor 41 to the transmission shafts 43 on both sides, so that the transmission shafts 43 on both sides rotate around their own axes. The second commutator 53 commutates the power transmitted to the transmission shafts 43 on both sides again, and transmits the power to the rotary reducer 51. Then the rotary reducers 51 on both sides output the power to drive the flip frame 2 to flip and position. Through the coordinated use of the transmission shafts 43, the second commutator 53 and the rotary reducer 51 symmetrically arranged on both sides of the first commutator 42, when the servo motor 41 is started, the rotary reducers 51 on both sides can simultaneously respond and drive the flip frame 2 to flip and position. The two sides of the flip frame 2 have high synchronization and strong structural stability, which is safe and reliable.

[0038] The flip assembly 5 also includes a planetary reducer 52, which is arranged between the second commutator 53 and the rotary reducer 51. Specifically, the planetary reducer 52 is fixedly mounted on the mounting frame 1, and the output end of the second commutator 53 is fixedly connected to the input end of the planetary reducer 52, and the output end of the planetary reducer 52 is fixedly connected to the input end of the rotary reducer 51. The planetary reducer 52 is arranged to ensure that the flip drive unit can realize stable operation and output appropriate torque to the rotary reducer 51, so as to ensure the stable operation of the entire device.

[0039] Furthermore, the transmission shaft 43 and the second commutator 53 are fixedly connected by a coupling 54, and the second commutator 53 and the planetary reducer 52 are also fixedly connected by a coupling 54. The provision of the coupling 54 is conducive to ensuring that the structures on both sides thereof rotate together when transmitting motion and power, and can reduce the possibility of separation of the structures on both sides under normal circumstances, thereby ensuring the stability of the operation of the device.

[0040] Reference Figure 1 and Figure 2 The pneumatic chuck assembly 3 is slidably arranged on the turning frame 2, and a linear guide assembly 7 is fixedly arranged on the turning frame 2. The pneumatic chuck assembly 3 includes a pneumatic clamp 31 and a mounting seat 32. The pneumatic clamp 31 is fixedly mounted on the mounting seat 32. The linear guide assembly 7 drives the pneumatic chuck assemblies 3 on both sides to move toward or away from each other along the length direction of the turning frame 2, so that the distance between the clamps of the pneumatic clamp 31 can be adaptively adjusted according to the width of the coil 8, so that the winding turret mechanism of the coating machine can carry out the winding and unwinding of coils 8 of more width specifications, which is conducive to reducing the waste of coils 8 caused by multiple roll changes when producing small coils 8.

[0041] Specifically, the linear guide assembly 7 includes a linear guide rail 71, a slider 72 and a driving member, the mounting seat 32 is fixedly connected to the slider 72, and the driving member drives the slider 72 to slide on the linear guide rail 71 to change the distance between the clamps of the pneumatic clamp 31. Furthermore, the linear guide rail 71 is a roller-type linear guide rail 71, which has the advantages of low friction and high precision, and the roller-type linear guide rail 71 has a strong bearing capacity and can withstand a large load. When performing the winding and unwinding operation of the large coil 8, it can also ensure stable operation and high precision.

[0042] The implementation process of the utility model is:

[0043] When the equipment is running, the servo motor 41 drives the transmission shaft 43 on both sides of the first commutator 42 to rotate, and the transmission shaft 43 transfers power to the second commutator 53 through the coupling 54. After the second commutator 53 is reversed, the power is transmitted to the coupling 54 on the other side of the second commutator 53, and then transmitted to the planetary reducer 52. The planetary reducer 52 transmits the power to the rotary reducer 51. The rotary reducers 51 on both sides simultaneously drive the rotating main shafts 61 on both sides to rotate, and finally drive the turning frame 2 to switch the target station, thereby realizing the turning and positioning of the overlong and overweight coil 8.
