Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0028] This embodiment provides a multi-station glue spraying rotating mechanism, see Figure 1 , 2 ,include:

[0029] A turntable assembly 1, wherein the bottom of the turntable assembly 1 is supported by a support frame 2;

[0030] The workstation units are multiple in number and are installed in a ring array on the turntable assembly 1. They can rotate clockwise / counterclockwise on a horizontal plane under the drive of the rotating assembly;

[0031] There are three workstation units, which are distinguished by function as a loading unit 3, a glue spraying unit 4 and a unloading unit 5. The operator loads the leather cover 22 in the loading unit 3, and the turntable assembly 1 controls the leather cover 22 in the loading unit 3 to rotate 120 degrees clockwise / counterclockwise to the glue spraying unit 4, and the leather cover 22 is glued in the glue spraying unit 4. After the glue spraying is completed, the turntable assembly 1 controls the leather cover 22 in the glue spraying unit 4 to rotate 120 degrees clockwise / counterclockwise to the unloading unit 5. The leather cover 22 after the glue spraying is removed in the unloading unit 5, and the turntable assembly 1 continues to control the rotation of the working unit to repeat the above-mentioned loading, glue spraying and unloading processes. Compared with the traditional leather cover 22 set on a glue spraying station for operation, in this solution, multiple stations and multiple people collaborate to achieve uninterrupted operation, which greatly improves the glue spraying efficiency.

[0032] In a specific embodiment, the structure of the turntable assembly 1 includes: a turntable 6, a fixed seat 7 and a motor drive unit. The fixed seat 7 is installed below the turntable 6 to support the turntable 6. The turntable 6 and the fixed seat 7 are connected by a bearing 8, so that the turntable 6 can rotate around its own axis above the fixed seat 7. The motor drive unit includes a transmission rod 19 arranged at the bottom of the turntable 6. The transmission rod 19 is in a vertical direction, and a bevel gear 10 is fixed at its end. The motor drive unit also includes a horizontal transmission rod 11, and a bevel gear 12 meshing with the bevel gear 10 is arranged at the end of the transmission rod 11. The other end of the transmission rod away from the bevel gear 12 is fixedly connected to the drive shaft of the motor 13 through a coupling. Through the above, the motor drive unit can control the horizontal rotation movement of the turntable 6 by rotating the transmission rod 19 and the transmission rod 211, thereby realizing precise driving and control of the turntable 6.

[0033] In a further embodiment, the turntable assembly 1 structure further includes a housing 14, which is disposed outside the turntable 6, the fixing base 7, and the motor drive unit to wrap and protect these components, prevent external objects from entering, and provide structural support and beautify the appearance. The housing 14 is generally made of a solid material, such as metal or plastic, with appropriate strength and durability.

[0034] The functions of the housing 14 include but are not limited to:

[0035] Protecting internal components: The housing 14 can effectively protect the internal components such as the rotating table 6, the fixing base 7 and the motor drive unit from being damaged or disturbed by external objects. This is crucial for the normal operation and stability of the device.

[0036] Prevent dust and debris from entering: The housing 14 can prevent dust, water vapor and other debris from entering the interior, keep the internal environment clean and dry, and reduce equipment failures and maintenance times.

[0037] Providing structural support: As a part of the external structure, the shell 14 can provide additional structural support to enhance the stability and load-bearing capacity of the entire turntable assembly 1.

[0038] Appearance beautification: The design and appearance of the shell 14 can be beautified according to actual needs, making the appearance of the turntable assembly 1 more beautiful and neat, thereby enhancing the visual appeal and market competitiveness of the product.

[0039] Therefore, the shell 14 plays a very important role in the structure of the turntable assembly 1. It not only protects the internal components, but also provides structural support and beautifies the appearance, thereby ensuring the normal operation and good appearance of the entire turntable assembly 1.

[0040] In a specific embodiment, see Figure 3 , 4 The structures of the feeding unit 3, the glue spraying unit 4 and the unloading unit 5 are consistent, including:

[0041] The body 15 is a rectangular frame structure composed of several plates, and is hollow inside, and is used to install components such as cylinders and sensors;

[0042] Support members, there are two of them, which are respectively arranged at the left and right ends of the body 15, one of which is fixed on the body 15, and the other is connected to the body 15 through a telescopic component. The support members are used to open the leather case 22 to both sides to ensure that the leather case 22 remains open during the glue application process;

[0043] The profiling plate 16 is installed on the upper and lower end surfaces of the main body 15. The profiling plate 16 is adapted to the shape of the leather case 22 so that the surface of the leather case 22 can be laid flat on the profiling plate 16 to provide a stable working surface for brushing glue.

[0044] The connecting rod 17 is fixed on the side plate of the main body 15, one end of which is fixedly connected to the main body 15, and the other end is threadedly connected to the rotating table 6. The function of this rod is to fix the main body 15 on the rotating table 6. Through the connection of the connecting rod 17, the movement on the rotating table 6 can directly affect the main body 15, thereby realizing the synchronous movement of the two.

[0045] With the above technical solution, the support member can stretch and fix the leather cases 22 of different sizes. By installing the profiling plate 16 corresponding to the leather case 22 on the main body 15, it is convenient to apply glue to the surface of the leather case 22, making the glue application uniform. Through the design of the support member and the profiling plate 16, it can adapt to leather cases 22 of different sizes and ensure that the surface of the leather case 22 remains flat and uniform during the glue application process. This design makes the glue application process simpler and more efficient, and at the same time improves the quality and stability of the glue application, providing convenience and guarantee for related production processes.

[0046] Further, the connection method between the connecting rod 17 and the rotating table 6 is that the rotating table 6 is provided with a threaded hole 20, and the end of the connecting rod 17 is correspondingly provided with an external thread 21. The threaded connection method can facilitate installation and disassembly. Just screw the threaded end of the connecting rod 17 into the threaded hole 20 on the rotating table 6 and fix the other end on the main body 15 to complete the connection. Such a design makes installation and maintenance more convenient and fast.

[0047] Further, the support member includes a first support member 18 and a second support member 19, and their shapes are both "C"-shaped. Among them, the first support member 18 is connected to the main body 15 through a telescopic assembly, while the second support member 19 is fixedly connected to the other end of the main body 15. When the leather case 22 is sleeved on the main body 15, the stretching length of the first support member 18 can be adjusted, so as to realize the stretching of the two ends of the leather case 22 by the first support member 18 and the second support member 19. This design makes the support system have better adaptability, can flexibly adapt to leather cases 22 of different sizes, and ensures the stability and uniformity of the leather case 22.

[0048] Further, the telescopic assembly includes a telescopic cylinder (inside the bellows 23), a bellows 23, a connecting plate 24 and a cylinder mounting seat 25. The cylinder mounting seat 25 is fixedly arranged inside the main body 15, and the fixed end of the telescopic cylinder is connected and fixed to the cylinder mounting seat 25. The first support member 18 is fixedly arranged at the piston end of the telescopic cylinder, while the connecting plate 24 is fixed to one end of the main body 15. The bellows 23, as a telescopic member, is connected and fixed to the connecting plate 24 at one end and to the first support member 18 at the other end. Through such a design, the telescopic cylinder drives the first support member 18 to reciprocate along the length direction of the main body 15, so as to achieve the purpose of adjusting the distance between the first support member 18 and the second support member 19. This structural design makes the entire support system more flexible, can adapt to leather cases 22 of different sizes, and ensures the accuracy and stability of the installation of the leather case 22.

[0049] It should be noted that, in addition to manual loading, glue spraying and unloading, the corresponding operations in the loading unit 3, the glue spraying unit 4 and the unloading unit 5 in the utility model can also be performed in conjunction with a robotic arm, which can further improve the automation level of the equipment, realize unmanned and uninterrupted operation, and greatly improve the glue spraying efficiency.

[0050] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
