[0002] Faucet is the popular name for water valve, which is used to control the size of the water flow switch and has the effect of saving water. The faucet is updated and replaced very quickly, from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control faucet, stainless steel double-temperature double-control faucet, and kitchen semi-automatic faucet. Now, more and more consumers will consider the material, function, shape and other aspects when purchasing faucets.

[0003] During the faucet assembly process, the cap needs to be tightened, and the traditional tightening method is that multiple assemblers tighten it manually. The efficiency of manual tightening is low, and the task volume is large, which increases labor costs. The existing method uses a screwing mechanism to achieve rapid cap screwing, but the existing equipment can only perform simple screwing. When in use, the workpiece to be screwed is installed and then screwed through the equipment. After the screwing is completed, the screwed workpiece needs to be disassembled before the new workpiece is installed. It does not have a corresponding unloading mechanism, which increases the operation steps and reduces the production efficiency. In addition, the disassembly and assembly work is performed at the same workstation, which is easy to cause confusion. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: an automatic cap screwing mechanism for kitchen faucet assembly, comprising: a workbench 1; a rotating seat 2, the rotating seat 2 is rotatably arranged on the top of the workbench 1 through a rotating shaft, and workpiece embedding grooves 19 for installing component accessories are equidistantly provided on the top of the rotating seat 2; a No. 3 linear module 6 is arranged above the workbench 1, and a lifting frame 7 is fixedly installed on the movable slide of the No. 3 linear module 6, and a tightening sleeve 9 for screwing the cap is installed at the bottom of the lifting frame 7; a rotating arm 15 is rotatably arranged on one side of the lifting frame 7, and a pneumatic clamp 18 for unloading is installed at the end of the rotating arm 15; a rotating driving part is arranged on the outer side of the lifting frame 7, and the rotating driving part includes a driving cylinder 10 fixedly installed on one side of the lifting frame 7, and a driving rack 11 is fixedly connected to the output end of the driving cylinder 10, which is used to drive the rotating arm 15 to rotate to a specified angle for unloading when the lifting frame 7 is raised to a specified height.

[0025] It should be noted that the utility model is provided with a PLC controller and an operation panel. The accessories to be screwed are placed in sequence in the workpiece embedding groove 19 on the top of the rotating seat 2. The No. 1 servo motor 3 drives the rotating seat 2 to rotate counterclockwise. After the No. 1 servo motor 3 drives the rotating seat 2 to rotate to a specified angle, the workpiece is located below the tightening sleeve 9. The controller controls the No. 3 linear module 6 to drive the lifting frame 7 to move. When the lifting frame 7 is contacted with the travel switch at the bottom of the No. 3 linear module 6, the No. 2 servo motor 8 drives the tightening sleeve 9 to rotate through the transmission belt assembly, so that the top cover is tightened by tightening the sleeve 9. When the cylinder 9 is screwed, the pneumatic clamp 18 is located on the outside of the previously screwed workpiece and clamps the workpiece by tightening. Under the action of the timer, the No. 3 linear module 6 drives the lifting frame 7 to rise. When the infrared sensor 20 is at the same height as the contact block during the rising process, the driving cylinder 10 drives the rotating arm 15 to rotate through the driving rack 11 and the driving gear 13, so that the pneumatic clamp 18 is located above the storage box. When the driving cylinder 10 reaches the limit position, the pneumatic clamp 18 opens, allowing the workpiece to fall into the storage box. A conveyor belt can be set at the bottom of the storage box to make the storage box move slowly to avoid collision caused by falling workpieces.

[0026] like Figure 1 As shown, a servo motor No. 3 is fixedly connected to the bottom of the workbench 1, and the output end of the servo motor No. 3 is connected to the center of the bottom of the rotating seat 2 by bolts.

[0027] It should be noted that the No. 1 servo motor 3 of the utility model is electrically connected to the controller. The No. 1 servo motor 3 has a position feedback device (such as an encoder), which is connected to the PLC to realize position closed-loop control. In the PLC program, the fixed angle of each rotation of the rotating disk is set so that the servo motor can drive the rotating disk to rotate a fixed angle each time, so that each time the workpiece to be screwed is located below the tightening sleeve 9, and the screwed workpiece is located below the pneumatic clamp 18.

[0028] like Figure 1 , 2 As shown, a linear module No. 1 4 is fixedly connected to the top of the workbench 1, a linear module No. 2 5 is installed on the movable slide of the linear module No. 1 4, the linear module No. 1 4 and the linear module No. 2 5 are vertically arranged, and a linear module No. 3 6 is installed on the movable slide of the linear module No. 2 5.

[0029] It should be noted that the utility model can replace the rotating seat 2 according to the different workpieces, and at the same time adjust the position of the tightening sleeve 9 in the X-axis direction through the No. 1 linear module 4, and adjust the position of the tightening sleeve 9 in the Y-axis direction according to the No. 2 linear module 5. In this way, the position of the tightening sleeve 9 is adjusted according to the rotating seat 2, so that the tightening sleeve 9 is placed directly above the workpiece embedding groove 19, so that it can adapt to workpieces of different models.

[0030] like Figure 2 , 3 As shown, a No. 2 servo motor 8 is installed on the top of the lifting frame 7, and the No. 2 servo motor 8 is connected to the tightening sleeve 9 through a transmission belt assembly.

[0031] It should be noted that the transmission belt assembly of the utility model includes two pulleys and a transmission belt mounted on the outside of the two pulleys for transmitting the two pulleys. The two pulleys are respectively connected to the output end of the second servo motor 8 and the top of the tightening sleeve 9. The tightening sleeve 9 is driven to rotate by the second servo motor 8 to tighten the screwing part.

[0032] like Figure 3 , 4 As shown, a support block 12 is fixedly connected to one side of the lifting frame 7, a rotating shaft 14 is rotatably connected to the middle part of the support block 12, the bottom of the rotating shaft 14 is fixedly connected to the rotating arm 15, the top of the rotating shaft 14 is fixedly connected to the driving gear 13, the driving rack 11 is meshed with the driving gear 13, a limiting rod 17 is fixedly connected to the top of the support block 12, a limiting groove 16 is provided in the middle part of the driving rack 11, the limiting rod 17 is stuck in the limiting groove 16 and is slidably connected to the limiting groove 16, an infrared sensor 20 is fixedly connected to one side of the No. 3 linear module 6, and a contact block cooperating with the infrared sensor 20 is provided on one side of the lifting frame 7.

[0033] It should be noted that when the No. 3 linear module 6 of the utility model drives the lifting frame 7 to rise, when the contact block is at the same height as the infrared sensor 20, the infrared sensor 20 detects the information, converts it into a signal and sends it to the controller, the controller receives the signal and processes it, and generates a corresponding control signal according to a preset control algorithm; the control signal is transmitted to the driving cylinder 10 through the output module, the driving cylinder 10 pulls the driving rack 11 to slide along the limit rod 17 on the top of the support block 12, the driving rack 11 drives the rotating shaft 14 through the driving gear 13, the rotating shaft 14 drives the rotating arm 15 to rotate, and the rotating arm 15 drives the pneumatic clamp 18 to rotate to the specified position, when the driving cylinder 10 moves to the extreme position, the pneumatic clamp 18 opens, so that the workpiece falls into the material receiving box.
