[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] like Figures 1 to 21The valve assembly assembly device of this application is used to assemble valve assembly 10, including: a station indexing plate assembly 20, including a fixed plate 210 and a rotatable turntable 220. The fixed plate 210 is disposed on a support base 30, and a plurality of stations 40 are provided on the fixed plate 210 at intervals around the circumference of the turntable 220. The station indexing plate assembly 20 also includes a plurality of workpiece bearing portions 50 at intervals around the rotation axis of the turntable 220; a valve needle assembly 1, a nut assembly 2, a nut locking assembly 3, a nut connecting plate assembly 4, a stop ring assembly 5, and a stop ring locking assembly 6 are arranged at intervals around the circumference of the station indexing plate assembly 20 and are arranged in a one-to-one correspondence with at least a portion of the plurality of stations 40, so as to operate the parts to be assembled on the workpiece bearing portions 50 rotated to the corresponding station 40 to form valve assembly 10.

[0051] In this way, the valve assembly device of this application realizes automated assembly in a production line by distributing different assembly steps to multiple workstations of the workstation indexing plate assembly. This greatly shortens the assembly time of a single valve assembly and improves the throughput of the overall assembly line. In this application, each assembly component, such as the valve needle assembly component, nut assembly component, and nut locking component, precisely matches the workpiece bearing part on the workstation indexing plate assembly, ensuring the correct assembly position and angle of each component. This avoids errors caused by manual operation and improves the assembly accuracy. Furthermore, this application adopts a unified assembly process and standard, and all valve components undergo the same assembly process, which helps to improve the consistency and reliability of product quality, reduce the product failure rate caused by assembly differences, and effectively solve the problem of low assembly efficiency of valve cores and nuts in the prior art.

[0052] like Figures 4 to 6As shown, the valve assembly 10 includes a valve needle 110. The valve needle assembly 1 further includes: a first lateral movement module 11, at least partially movably disposed on the support base 30 along a first direction parallel to the support base; a first longitudinal movement module 12 and a second longitudinal movement module 13, spaced apart on the moving portion of the first lateral movement module 11, at least portions of the first longitudinal movement module 12 and the second longitudinal movement module 13 moving along a second direction perpendicular to the support base; and a valve needle conveying component 14, disposed on the support base 30 and located on the side of the first lateral movement module 11 away from the workstation indexing plate assembly 20, including a first drive unit 141 and a valve needle tray 142, on which a plurality of valve needles 110 are disposed, and the output end of the first drive unit 141 is drivenly connected to the valve needle tray 142. The valve needle tray 142 is driven to move in a predetermined direction; the valve needle gripping component 15, the moving part of the first longitudinal moving module 12 is connected to the valve needle gripping component 15 so that the valve needle gripping component 15 moves in a second direction perpendicular to the support base 30 to grip the valve needle 110 located on the valve needle tray 142; the valve needle detection component 16 is located between the valve needle gripping component 15 and the station indexing plate assembly 20 to carry and detect the valve needle 110 from the valve needle gripping component 15; the valve needle mounting component 17, the moving part of the second longitudinal moving module 13 is connected to the valve needle mounting component 17 so that the valve needle mounting component 17 moves in a second direction perpendicular to the support base 30 to grip the valve needle 110 located on the valve needle detection component 16 and mount it onto the corresponding workpiece bearing part 50.

[0053] This application utilizes the combined movement of a first lateral movement module, a first longitudinal movement module, and a second longitudinal movement module. This allows the valve needle assembly assembly to grasp, inspect, and install the valve needle with higher precision and flexibility, ensuring the valve needle is accurately placed in the preset position, thereby improving assembly accuracy and product quality. The introduction of the valve needle inspection component enables real-time quality control during the assembly process, automatically screening out unqualified valve needles and preventing defective products from entering subsequent assembly stages, significantly improving yield and overall assembly line efficiency.

[0055] The nut assembly assembly of this application ensures that the nut can move accurately above the valve needle according to the preset path through the precise control of the nut feeding component, the nut moving component, and the longitudinal and lateral moving modules, thereby achieving high-precision assembly of the nut and the valve needle and avoiding problems such as nut position deviation or unstable installation during assembly. The combined use of the nut vibratory plate and the nut transport track can continuously feed the nut to the nut moving component, avoiding waiting time and improving the throughput and capacity of the assembly line.

[0056] like Figure 9 and Figure 10As shown, the nut locking assembly 3 further includes: a nut locking assembly mounting base 31, disposed on the support base 30; a nut locking moving part 32, at least a portion of which is movably disposed on the nut locking assembly mounting base 31 along a second direction perpendicular to the support base 30; and a nut locking drive part 33, which is connected to the moving part of the nut locking moving part 32. A nut locking sleeve 331 is disposed on the output end of the nut locking drive part 33. The nut locking sleeve 331 is located above the corresponding workpiece bearing part 50. The inner wall surface of the nut locking sleeve 331 corresponds to the outer peripheral surface of at least a portion of the nut 120, so as to drive the corresponding nut 120 to rotate, so that the nut 120 is tightened on the valve needle 110.

[0057] In this application, the nut locking assembly, through the coordinated operation of the nut locking moving part and the nut locking driving part, can accurately tighten the nut onto the valve needle, ensuring a stable connection between the nut and the valve needle, avoiding connection problems caused by insufficient or excessive locking force, and improving the sealing performance and durability of the valve assembly. The corresponding setting of the nut locking sleeve and the outer circumference of the nut ensures the correct positioning and rotation of the nut during the locking process, avoiding the nut's offset or damage during the locking process, and improving locking accuracy and assembly quality.

The nut connecting plate is moved onto the nut connecting plate transport track 412; the nut connecting plate moving component 42 is disposed on the support base 30 and connected to the outlet of the nut connecting plate transport track 412 to receive and move the nut connecting plate 130 from the nut connecting plate transport track 412; the third lateral moving module 43 is at least partially movably disposed on the support base 30 along a fourth direction parallel to the support base 30; the fourth longitudinal moving module 44 and the fifth longitudinal moving module 45 are spaced apart from each other on the third lateral moving module 412.

[0061] The stop ring assembly component in this application ensures that the stop ring is accurately fitted onto the nut through precise positioning and multi-axis linkage control, avoiding assembly deviations and poor sealing, and significantly improving the assembly accuracy and functionality of the valve assembly. The automated design of the stop ring feeding component and assembly component enables continuous feeding and automated assembly of the stop ring without manual intervention, improving production efficiency and reducing downtime. By adjusting the parameters of the stop ring feeding component and assembly component, the system can adapt to the assembly requirements of stop rings of different sizes and types, enhancing the flexibility and scalability of the production line.
