[0031] Currently, the operation mode of seal ring assembly is mostly manual assembly operation, and the assembly efficiency of manual operation is low, which cannot meet the assembly speed of products, and thus cannot meet the market demand. To meet the market demand, it is necessary to improve the efficiency of seal ring assembly of products.

[0032] To solve the above problems, the present utility model proposes a middle turntable for seal ring assembly and a seal ring assembly machine, aiming to provide a middle turntable for seal ring assembly and a seal ring assembly machine that can improve the efficiency of product seal ring assembly. Figures 1 to 3 It is a schematic structural diagram of an embodiment provided for the middle turntable for seal ring assembly of the present utility model.

[0033] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the middle turntable 100 for seal ring assembly includes a mounting base 1, a carrier plate 2, and a plurality of carriers 3; the carrier plate 2 is movably mounted on the mounting base 1 and has a movement stroke of rotating along an axis extending in the vertical direction; the plurality of carriers 3 are arranged at intervals and evenly distributed on the circumferential side of the upper end surface of the carrier plate 2 for rotating and flowing through each station of the seal ring assembly machine along with the carrier plate 2; the carrier 3 is used for placing the seal ring.

[0034] The technical solution of the present utility model places the seal ring by using the carrier 3, and a plurality of the carriers 3 are arranged at intervals and evenly distributed on the circumferential side of the upper end surface of the carrier plate 2, so as to rotate and flow through each station of the seal ring assembly machine along with the carrier plate 2. Furthermore, a plurality of the seal rings can simultaneously perform different-step assembly processes, thereby improving the efficiency of the product assembling the seal ring.

[0035] Furthermore, please refer to Figure 2 , a plurality of accommodating grooves 31 are provided on the carrier 3, which are arranged at intervals and evenly, and the plurality of accommodating grooves 31 are all used for accommodating the seal ring. It can be understood that, in order to further improve the efficiency of assembling the seal ring and repeat the same assembling step for as many seal rings as possible at the same station, thereby further accelerating the assembling speed of the seal ring. In this application, two accommodating grooves 31 are provided on the carrier 3 for respectively accommodating two seal rings and performing the assembling steps on the two seal rings.

[0036] Furthermore, please refer to Figure 1, the middle turntable 100 for seal ring assembly further includes a negative pressure device 4, which is connected to the carrier 3; the bottom of the accommodating groove 31 is penetrated with an air hole 311, and the air hole 311 communicates with the negative pressure device 4 to fix the seal ring in the accommodating groove 31. It can be understood that, in some embodiments, due to the circumferential movement of the carrier plate 2, the seal ring is affected by the centrifugal force on the carrier plate 2 and disengages from the carrier 3, thereby affecting the special matching of the product to the seal ring; thus, in order to ensure that the seal ring does not disengage from the carrier plate 2 when flowing on the carrier plate 2, specifically, the middle turntable 100 for seal ring assembly further includes the negative pressure device 4 connected to the carrier 3; the bottom of the accommodating groove 31 is penetrated with the air hole 311, and the air hole 311 communicates with the negative pressure device 4, and then the negative pressure device 4 generates negative pressure, and through the air hole 311, the seal ring is firmly adsorbed in the accommodating groove 31.

[0037] In addition, please refer to Figure 2 , the carrier 3 includes a carrier seat 32 and a carrier plate 33; the carrier seat 32 is fixed on the carrier plate 2; the carrier plate 33 is adsorbed on the carrier seat 32 by the negative pressure device 4, and the accommodating groove 31 is recessed on the carrier plate 33. It can be understood that the models of the seal rings are ever-changing. In order to improve the adaptability of the middle turntable 100 for seal ring assembly, specifically, the carrier 3 includes the carrier seat 32 and the carrier plate 33; the carrier seat 32 is fixed on the carrier plate 2; the carrier plate 33 is adsorbed on the carrier seat 32 by the negative pressure device 4, and the accommodating groove 31 is recessed on the carrier plate 33, and the carrier plate 33 can have more models according to the model of the seal ring. In this way, for the assembly of different models of the seal rings, only the corresponding model of the carrier plate 33 is required in this application. In this way, the adaptability of the middle turntable 100 for seal ring assembly is further improved, and it can have more usage occasions.

[0038] Further, please refer to Figure 2 and Figure 3, the carrier base 32 is provided with a first negative pressure chamber 321; a second negative pressure chamber 331 is provided in the carrier plate 33, one end of the second negative pressure chamber 331 communicates with the first negative pressure chamber 321, and the other end communicates with the air hole 311. It can be understood that in order to adsorb the carrier plate 33 on the carrier base 32 and the sealing ring on the accommodating groove 31, the carrier base 32 is provided with the first negative pressure chamber 321; the carrier plate 33 is provided with the second negative pressure chamber 331, wherein one end of the second negative pressure chamber 331 communicates with the first negative pressure chamber 321, and the other end communicates with the air hole 311. In this way, the negative pressure generated by the negative pressure device 4 is transmitted in the first negative pressure chamber 321 and the second negative pressure chamber 331 until it is transmitted to the sealing ring through the air hole 311, so that the sealing ring is adsorbed in the accommodating groove 31, and at the same time the carrier plate 33 is adsorbed on the carrier base 32. In this way, when the carrier disk 2 rotates, the sealing ring and the carrier plate 33 will not be thrown out due to the centrifugal force of rotation, improving the reliability of the middle turntable 100 for assembling the sealing ring.

[0039] Further, please refer to Figure 3 , the carrier 3 further includes a seal 34 disposed at the connection between the first negative pressure chamber 321 and the second negative pressure chamber 331. It can be understood that the plane between the carrier plate 33 and the carrier base 32, and the first negative pressure chamber 321 and the second negative pressure chamber 331 communicate. If there is a difference in flatness between the carrier plate 33 and the carrier base 32 and there are defects on the joint surface, it will be difficult for the negative pressure generated by the negative pressure device 4 to be transmitted to the air hole 311. Therefore, the carrier 3 further includes the seal 34 disposed at the connection between the first negative pressure chamber 321 and the second negative pressure chamber 331 to ensure that there is no air leakage between the carrier base 32 and the carrier plate 33. In this way, the negative pressure generated by the negative pressure device 4 can be well transmitted to the air hole 311.

[0040] In addition, please refer to Figure 1, the middle turntable 100 for seal ring assembly further includes a pressure dividing device 5, which is installed on the air path between the negative pressure device 4 and the carrier 3 to evenly distribute the negative pressure to each of the accommodation grooves 31. It can be understood that, as described above, a plurality of the accommodation grooves 31 are provided on the carrier plate 33, and air holes 311 are opened at the bottoms of the accommodation grooves 31. The negative pressure generated by the negative pressure device 4 is used to adsorb the seal rings. In some embodiments, the second negative pressure chambers 331 corresponding to the accommodation grooves 31 are communicated as a whole. The drawback is that if there is a leaking air hole 311 in one place, the entire carrier plate 33 will not have the function of adsorbing the seal rings because the negative pressure leaks out. Therefore, to avoid this situation, the second negative pressure chambers 331 corresponding to the accommodation grooves 31 are independent of each other. Thus, the middle turntable 100 for seal ring assembly further includes the pressure dividing device 5, which is installed on the air path between the negative pressure device 4 and the carrier 3 to evenly distribute the negative pressure to each of the accommodation grooves 31. In this way, each of the accommodation grooves 31 has the ability to adsorb the seal rings.

[0041] In addition, please refer to Figure 1 , the middle turntable 100 for seal ring assembly further includes a direct drive motor 6. The direct drive motor 6 is installed on the installation base 1 and is drivingly connected to the carrier disk 2 to drive the carrier disk 2 to rotate about an axis extending in the vertical direction. It can be understood that, in order to realize the rotation of the carrier disk 2, in some embodiments, the driving member for driving the carrier disk 2 to rotate can be a rotating motor or other devices, but it has a large noise, a high space occupancy rate, and a slow response speed. Therefore, in another embodiment, the middle turntable 100 for seal ring assembly further includes the direct drive motor 6. The direct drive motor 6 is installed on the installation base 1 and is drivingly connected to the carrier disk 2 to drive the carrier disk 2 to rotate about an axis extending in the vertical direction. The direct drive motor 6 has the following advantages:

[0042] High efficiency: The direct drive motor 6 avoids the energy loss caused by traditional transmission devices, improves the energy utilization rate, and makes the motor more efficient.

[0043] High precision: Due to the absence of the influence of the transmission device, the direct drive motor 6 has a very high precision, can directly drive the load, reduces the positioning error caused by the mechanical structure, and improves the process precision.

[0044] High response speed: The direct drive motor 6 can quickly respond to the drive signal, and has a fast response speed for speed regulation, and is suitable for occasions that require quick response.

[0045] Low noise: The direct drive motor 6 has a simple structure, reduces mechanical contact and vibration, and effectively reduces noise and vibration.

[0046] Easy to maintain: The direct drive motor 6 has a simple structure, reducing the transmission part, lowering the probability of mechanical failures, and facilitating maintenance at the same time.

[0047] High acceleration: The direct drive motor 6 has a high acceleration, even reaching more than 30 to 50 times the gravitational acceleration.

[0048] Wide range of applications: The direct drive motor 6 is widely used in various industries, including but not limited to industrial, medical equipment, automation equipment, robotics and other fields.

[0049] High speed and high acceleration: The normal peak speed of the direct drive motor 6 can reach 5 - 10 m / s, and the acceleration can reach 3 - 5g or higher.

[0050] Further, please refer to Figure 1 , the middle turntable 100 for seal ring assembly further includes a conductive slip ring 7, which is fixedly installed relative to the carrier plate 2 and is drivingly connected to the direct drive motor 6. It can be understood that the air paths on the negative pressure device 4 are respectively connected and evenly distributed around the circumference of the carrier plate 2. If the negative pressure device 4 does not rotate with the carrier plate 2, these air paths and other wires will get entangled. Therefore, the middle turntable 100 for seal ring assembly further includes the conductive slip ring 7, which is fixedly installed relative to the carrier plate 2 and is drivingly connected to the direct drive motor 6, thereby driving the negative pressure device 4 to work and rotating with the negative pressure device 4 at the same time, so that the rotation of the negative pressure device 4 is relatively stationary with respect to the carrier plate 2, thus avoiding the possibility of line entanglement and resulting in failures.

[0051] The present utility model also proposes a seal ring assembly machine, which includes the middle turntable 100 for seal ring assembly. The specific structure of the middle turntable 100 for seal ring assembly refers to the above-mentioned embodiment. Since the seal ring assembly machine adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated herein one by one.

[0052] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
