Description

Technical Field

[0001] This invention relates to the field of equipment assembly technology, and in particular to a water jet and mixing valve body installation machine. Background Technology

[0002] In fluid control systems such as plumbing and air conditioning, the assembly of the water jet and mixing valve body is a critical production step, and its assembly quality directly affects the fluid control accuracy and service life of the equipment. Currently, the industry mostly uses manual or semi-automated equipment for assembly, which presents the following problems: In the existing assembly method, components such as connecting sleeves, water jets, and water distribution rings need to be manually positioned and installed one by one. This is not only inefficient, but also prone to poor component fit due to operational errors. For example, the coaxiality deviation between the water distribution ring and the connecting sleeve may cause fluid leakage. In addition, the assembly of small components such as stainless steel mesh and plugs relies on manual placement, resulting in a high rate of omissions and misassemblies. Furthermore, the assembly of water jets is disconnected from the assembly of the mixing valve body, requiring manual transfer of semi-finished products, which further increases the production cycle and quality risks.

Furthermore, the feeding and connecting device 200 uses a vibrating feeder in conjunction with a pneumatic manipulator to place the connecting sleeves one by one onto the fixing fixture 120. Each assembly mechanism is arranged sequentially along the conveying direction of the conveying mechanism 110, achieving streamlined operation.

[0020] This installation machine achieves full automation from feeding the connecting sleeve to assembling the water jet and mixing valve body by integrating various assembly mechanisms. The conveying mechanism drives the continuous rotation of the fixed fixture, and the various mechanisms work together to significantly improve production efficiency. At the same time, mechanical positioning ensures assembly accuracy and reduces human operation errors, while the modular design facilitates maintenance and adapts to the assembly needs of different product specifications.

A positioning cylinder 323 is provided on the output end of the water-distributing ring feeding component 321, and a receiving positioning seat 324 is connected to the positioning cylinder 323. The positioning cylinder 323 can drive the receiving positioning seat 324 to receive the water-distributing ring output from the output end of the water-distributing ring feeding component 321 in the first position and transfer it to the second position. When the receiving positioning seat 324 is in the second position, the water-distributing ring installation robot 322 can clamp the water-distributing ring on the receiving positioning seat 324 and transfer it to the connecting sleeve installed on the fixed fixture 120. The water distribution ring feeding assembly 321 is a vibrating feeder. The straight vibrating track at the output end will transport the water distribution ring in an orderly manner. After the positioning cylinder 323 drives the receiving positioning seat 324 to receive the water distribution ring at the first position, it will drive the water distribution ring to the second position. The water distribution ring installation robot 322 will clamp the water distribution ring and install it in the connecting sleeve.

[0023] It should be noted that in this application, the water ring installation robot 322 and the water jet installation robot 314 share a single robot body, and perform separate operations through different end effectors.

[0024] Reference Figure 4 and Figure 5As shown, the cap assembly mechanism 330 includes a cap vibrating feeder 331, an O-ring feeder 332, a transfer robot 333, a cap spraying treatment assembly 334, an O-ring assembly assembly, and a cap assembly robot 335, all mounted on the frame 100. The transfer robot 333 can transfer the caps output by the cap vibrating feeder 331 to the cap spraying treatment assembly 334 and transfer the O-rings output by the O-ring feeder 332 to the working end of the O-ring assembly assembly. The transfer robot 333 can transfer the caps that have been sprayed with oil from the cap spraying treatment assembly 334 to the working end of the O-ring assembly assembly. The O-ring assembly assembly can open the O-rings and fit them onto the caps. The cap assembly robot 335 can transfer the caps from the O-ring assembly assembly and install them onto the connecting sleeve on the fixing fixture 120. Both the transfer robot 333 and the cap assembly robot 335 are multi-axis robots, configured according to actual needs. The screening track at the output end of the cap vibrating feeder 331 ensures that the caps are oriented in the same direction. The transfer robot 333 transfers the caps to the cap oil spraying assembly 334 for lubricant spraying, and then transfers them to the O-ring assembly assembly.

Opening and closing cylinder 338 can drive the pair of grippers 339 to open the O-rings. Lifting cylinder 33a pushes the O-rings through L-shaped support plate 33b so that the O-rings slide onto the plugs. The O-rings output by O-ring feeder 332 are transferred by transfer robot 333 to the grippers 339 of O-ring assembly assembly. Opening and closing cylinder 338 drives grippers 339 to open the O-rings so that they are mounted in the plug mounting groove. Finally, plug assembly robot 335 installs the plugs onto the connecting sleeve. In the above embodiments, the adjusting screw module 336 of the O-ring assembly component drives the support 337 to move, adapting to the assembly requirements of plugs of different specifications. The lifting cylinder 33a drives the L-shaped support plate 33b to rise and fall, adjusting the height of the plug. After the gripper 339 passes through the through hole 33c, it opens the O-ring, ensuring that the O-ring is accurately fitted onto the plug. At this time, the L-shaped support plate 33b pushes the O-ring on the gripper 339 into the mounting groove of the plug or the corresponding mounting area.

[0026] Reference Figures 1 to 4 As shown, the stainless steel mesh assembly mechanism 340 includes a stainless steel mesh feeder 341 and a stainless steel mesh assembly robot 342. The stainless steel mesh feeder 341 is a stacking feeder, which, in conjunction with a vibrating feeder, separates and pushes out the stainless steel mesh one by one.

Each adjusting cylinder 424 can clamp the corresponding sides of the connecting sleeve through the adjusting plate 425 and the corresponding limiting plate 423. The valve body transfer robot 410 is used to transfer the connecting sleeve that has been assembled on the conveying mechanism 110 to the clamping space. The mixing valve assembly robot 450 can install and fix the valve plugs and mixing valve assemblies output from the valve plug feeding assembly 430 and the mixing valve feeding assembly 440 onto the connecting sleeves in the clamping space. The slide table 421 drives the mounting plate 422 to move and adjust its position to match the movement of the mixing valve assembly robot 450. The limiting plate 423 and the adjusting plate 425 on the mounting plate 422 form a clamping space. The adjusting cylinder 424 pushes the adjusting plate 425, which, together with the limiting plate 423, clamps the connecting sleeve to ensure the positioning accuracy during the assembly of the mixing valve body. The valve body transfer robot 410 transfers the connecting sleeve, which has completed the water jet assembly, to the clamping space. The mixing valve assembly robot 450 picks up materials from the valve plug feeding assembly 430 and the mixing valve feeding assembly 440 respectively, completing the installation of the valve plug and the mixing valve assembly.

[0029] To facilitate material handling, the valve plug feeding assembly 430 uses a vibrating feeder in conjunction with a linear vibrating track to orderly output valve plugs to preset picking positions. However, the mixing valve assembly, due to its elongated and slender shape, is not conducive to feeding. Therefore, in one embodiment of this application, the mixing valve feeding assembly 440 mounts multiple mixing valve assemblies on a material tray, facilitating subsequent gripping by the mixing valve assembly robot 450. The grippers of the mixing valve assembly robot 450 are adapted to the valve plugs and mixing valve assemblies, achieving precise gripping and installation.

The flat support plate 445 can support the material tray lifted by the two picking cylinders 448. A suction cup picker 44a can be lifted and lowered on the top of the lifting frame 441. The suction cup picker 44a can adjust the position of the mixing valve assembly on the material tray in cooperation with the flat support plate 445. The mixing valve assembly robot 450 can install and fix the mixing valve assembly on the material tray onto the connecting sleeve on the fixture transfer mechanism 420. A horizontal conveyor 442 transports a tray loaded with mixing valve assemblies. A lifting platform 443 raises the tray to the top of a lifting frame 441. A lifting clamping cylinder 447 drives a material-picking cylinder 448 to descend. Two material-picking cylinders 448 respectively drive clamping plates 449 to lift the tray from its bottom or side wall. A horizontal actuator 446 drives a flat support plate 445 to move along a horizontal rail 444 to receive the tray. A suction cup material picker 44a, in conjunction with the flat support plate 445, adjusts the position of the tray. A mixing valve assembly robot 450 picks up the material from the tray and installs it onto the connecting sleeve. The horizontal actuator 446 is a motor-driven synchronous belt design, but it can also be a linear electric cylinder design.

[0031] Reference Figure 7 As shown, the mixing valve body assembly device 400 also includes a screw-locking assembly 460, which is vertically mounted on the frame 100. The screw-locking assembly 460, in conjunction with the fixture transfer mechanism 420, tightens the screws on the connecting sleeve. Specifically, the slide table 421 drives the mounting plate 422 to move and adjust its position. The working end of the screw-locking assembly 460 lowers or rises to tighten the screws, completing the final assembly. The screws are pre-installed on the mixing valve assembly or valve plug; the screw-locking assembly 460 only needs to tighten the screws onto the connecting sleeve. A conventional electric screwdriver is used for the screw-locking assembly 460.
