The assembly speed is high and efficient. In addition, the positions of each mechanism in the front and rear sections are compactly arranged, which can reduce the space occupied by the entire assembly machine and the space occupied in the production workshop.

[0065] Furthermore, through the ingenious design of the position setting and arrangement of the assembly parts mechanism at the front and rear ends of the assembly machine, combined with the multiple flipping mechanism, during assembly, the front end clamps the parts and assembles them sequentially at the workstation as valve stem shell, valve seat, rubber gasket, irregular ring, valve stem, upper ceramic plate, and lower ceramic plate to form the first semi-finished chip; the rear end first clamps the first semi-finished chip and sequentially inserts the assembly rubber ring, outer shell and first O-ring to form the second semi-finished valve core, and then clamps the second O-ring onto the transfer mechanism to assemble with the second semi-finished valve core; compared with assembling the parts sequentially at the workstation, the assembly efficiency is greatly improved; and the distribution of each assembly mechanism is reasonable and compact, saving space.

[0066] In specific implementation, the material conveying device 110 is a turntable structure, and a motor that drives the turntable to rotate is provided at the bottom of the turntable; a number of workstations 111 are arranged sequentially along the material conveying direction, i.e., the circumferential direction, on the outer circumference of the turntable; each workstation 111 is provided with at least a valve stem housing fixing hole 1111 and a valve seat fixing hole 1112 along the material conveying direction; the shape of the valve stem housing fixing hole 1111 is adapted to the bottom shape of the valve stem housing G70; the shape of the valve seat fixing hole 1112 is adapted to the upper end shape of the valve seat G20.

[0067] Furthermore, the valve stem housing assembly mechanism 120, the valve seat assembly mechanism 130, the irregular ring assembly mechanism 140, and the valve stem assembly mechanism 160 are each equipped with at least two of the following: material transfer grippers, rotating grippers, pressure rods, and adsorption devices.

[0068] In specific implementation, the valve stem housing assembly mechanism 120 includes a liftable first gripper 121 and a second gripper 122; the second gripper 122 can rotate horizontally; the first gripper 121 is used to clamp the valve stem housing G70 from the valve stem housing feeding device 126 into the valve stem housing fixing hole 1111 on the work station 111; when the first gripper 121 clamps the valve stem housing G70 into the valve stem housing fixing hole 1111, the second gripper 122 adjusts the position of the valve stem housing G70;

[0069] The valve seat assembly mechanism 130 includes a third gripper 131 and a fourth gripper 132 that can be raised and lowered independently; the fourth gripper 132 can rotate horizontally; the fourth gripper 132 is used to grip the valve seat G20 from the valve seat feeding device 1310 to the rubber pad feeding device 1121 to assemble the rubber pad G10; when the fourth gripper 132 returns to the valve seat feeding device 1310 to grip the valve seat G20, the third gripper 131 grips the valve seat G20 with the assembled rubber pad G10 into the valve seat fixing hole 1112 on the work station 111;

[0070] The irregular ring assembly mechanism 140 includes an independently liftable irregular ring transfer gripper 142 and a first pressure rod 145; the irregular ring transfer gripper 142 is used to grip the irregular ring G30 from the irregular ring feeding device 141 and assemble it with the irregular ring mounting groove on the valve seat G20 at the work station 111; when the irregular ring transfer gripper 142 grips the irregular ring G30 from the irregular ring feeding device 141 again, the first pressure rod 145 presses the irregular ring G30 on the work station 111 against the irregular ring mounting groove, and engages the irregular ring G30 in the irregular ring mounting groove;

[0071] The valve stem assembly mechanism 160 includes a liftable fifth gripper 165 and a first adsorption device 166. The first adsorption device 166 is used to adsorb the lower ceramic piece G50 to the valve stem feeding device 161 for assembly with the valve stem G60. The fifth gripper 165 is used to clamp the valve stem G60 with the lower ceramic piece G50 assembled on it and place it on the work station 111 for assembly with the valve stem housing G70. In this embodiment, the valve stem housing assembly mechanism 120, valve seat assembly mechanism 130, irregular ring assembly mechanism 140, and valve stem assembly mechanism 160 are equipped with at least two functional devices, which can save space and improve assembly efficiency and quality.

[0072] In specific implementation, the valve stem housing assembly mechanism 120 is equipped with a valve stem housing sensor 127; the valve seat assembly mechanism 130 has a valve seat detection sensor 149 at its rear end; the irregular ring assembly mechanism 140 has an irregular ring detection sensor 157 at its rear end; the valve stem assembly mechanism 160 has a valve stem detection sensor; the gasket assembly device 320 has a gasket sensor 324 in its parts mounting slot; the outer shell assembly device 330 has an outer shell sensor 333 in its parts mounting slot; the second O-ring assembly mechanism 350 has a second O-ring detection sensor in its parts mounting slot; and the gasket assembly device 1120 has a gasket sensor at its feeding end. All of the above sensors communicate with the controller. Part arrival sensors include, but are not limited to, pressure sensors and vision sensors. Detecting materials using pressure sensors and vision sensors is a common technique in this field and will not be elaborated upon here. The system detects whether the material is in place by using a part arrival sensor and sends the detection signal to the controller. When the part is not delivered to the corresponding position, the controller controls the corresponding mechanism to wait for the part to arrive before starting. This can avoid assembly abnormalities caused by feeding gaps when there is insufficient material in the feeding device, thereby reducing the output of defective products.

[0073] In specific implementation, the oiling device includes a first oiling device 1620 and a second oiling device 370. The first oiling device 1620 is located on one side of the valve stem assembly mechanism 161 and is used to apply oil to the side wall of the valve stem G60 after the lower ceramic plate G50 is assembled. The second oiling device 370 is located below the insertion mechanism 310 and is used to apply oil to the side wall of the first semi-finished valve core. The oiling device is connected to an oil injection machine, which supplies oil to the oiling device. The oiling device uses existing equipment, and its oiling principle and structure are existing technologies, which will not be described in detail here. In this embodiment, the design of the oiling device enables oil to be applied to the side wall of the valve stem G60, thereby reducing the frictional resistance between the valve stem G60 and the parts, improving the quality and efficiency of parts assembly, and reducing the defect rate. Especially in the case of the rear rubber gasket, outer shell, and first O-ring, which are all assembled by insertion, if the frictional resistance between the inner valve stem G60 and the parts is too large, it can easily affect the installation effect and increase the defect rate.

[0074] Furthermore, the oiling device below the insertion mechanism 310 is a second oiling device 370; the transfer mechanism 200 is laterally provided with the second oiling device 370 and the outer casing assembly device 330; the gasket assembly device 320 and the first O-ring assembly device 340 are respectively located on both sides of the outer casing assembly device 330. During assembly, the grippers of the insertion mechanism 310 move to the transfer mechanism 200 to grip the first semi-finished valve core; after gripping the first semi-finished valve core, the insertion mechanism 310's grippers move sequentially to the second oiling device 370, the gasket assembly device 320, the outer casing assembly device 330, and the first O-ring assembly device 340 to assemble the parts, and then return to the transfer mechanism 200 to place the assembled second semi-finished valve core on the transfer mechanism 200, allowing the transfer mechanism 200 to drive the second semi-finished valve core into the next part assembly position.

[0075] In this embodiment, the second oiling device 370, the outer shell assembly device 330, the gasket assembly device 320, and the first O-ring assembly device 340 can make the structure more compact on the one hand, and on the other hand, can minimize the movement trajectory of the transfer mechanism 200 along the part assembly sequence direction, thereby reducing the movement distance of the gripper of the insertion mechanism 310 and improving the part assembly efficiency.

[0076] like Figure 4 , Figure 7 As shown, the valve stem housing assembly mechanism includes a first gripper 121, a second gripper 122, a first slide rail 123, a first cylinder 1231, a second slide rail 124, a second cylinder 1241, a first rotary cylinder 125, a valve stem housing feeding device 126, a valve stem housing sensor 127, a valve stem housing rotating rod 128, a rotating housing clamping part 1281, a first bracket 129, and a valve stem housing installation detection sensor 1271, wherein;

[0077] The first support 129 and the valve stem housing feeding device 126 are both located on one side of the conveying device 110. The first support 129 is horizontally equipped with a first slide rail 123 and a first cylinder 1231. The first cylinder 1231 pushes the slider on the first slide rail 123 to move horizontally along the slide rail. The slider on the first slide rail 123 is vertically equipped with a second slide rail 124 and a second cylinder 1241. The second cylinder 1241 pushes the slider on the second slide rail 124 to move up and down. The slider on the second slide rail 124 is equipped with a first gripper 121 and a second gripper 122. The second gripper 122 is connected to the rotating end of the first rotary cylinder 125. The first rotary cylinder 125 drives the second gripper 122 to rotate horizontally. The feeding end of the valve stem housing feeding device 126 is equipped with a valve stem housing sensor 127 for detecting whether the valve stem housing is in place. A valve stem housing installation detection sensor 1271 is provided between the valve stem housing assembly station and the valve seat assembly station for detecting whether a valve stem housing is installed.

[0078] During valve stem housing assembly, at least one of the first gripper 121 and the second gripper 122 clamps the valve stem housing G70 from the valve stem housing feeding device 126 and places it into the valve stem housing fixing hole 1111 on the conveying device 111. When the valve stem housing G70 and the valve stem housing fixing hole 1111 are not aligned, the first rotary cylinder 125 drives the second gripper 122 to rotate horizontally to adjust the angle of the valve stem housing G70 so that the valve stem housing G70 can be inserted into the valve stem housing fixing hole 1111.

[0079] Preferably, the second gripper 122 is equipped with a valve stem housing position detection camera to detect whether the directional position of the valve stem housing is consistent with the valve stem housing fixing hole 1111, so as to adjust the rotation angle of the first rotary cylinder 125.

[0080] Preferably, the valve stem housing feeding device 126 adopts a feeding device with a fixed valve stem housing feeding direction, thereby avoiding the problem of inconsistent position and direction between the valve stem housing G70 and the valve stem housing fixing hole 1111. Feeding devices with a fixed feeding direction are also quite common in the art, and will not be described in detail here.

Then the movable rod of the sixth cylinder 1123 retracts downward so that the rubber pad with the adjusted angle is placed back into the rubber pad feeding end 1124, waiting to be assembled with the valve seat.

[0084] When assembling the gasket G10 and valve seat G20, the fourth gripper 132 picks up the valve seat G20 and places it on the gasket feeding end for gasket assembly. Then, the fourth gripper 132 returns to the valve seat feeding end to pick up the second valve seat G20. At this time, the third gripper 131 picks up the valve seat G20 with the gasket assembled on the gasket feeding end. When the fourth gripper 132 places the second valve seat G20 on the gasket feeding end for assembly, the third gripper 131 places the first valve seat G20 with the gasket assembled into the valve seat fixing hole 1112 on the conveying device 110, thus completing the assembly of the gasket G10 and valve seat G20.

Then, the irregular ring gripper 142 is horizontally braked to the irregular ring assembly station on the material conveying device 111 to assemble the irregular ring G30 with the valve seat G20. After that, the irregular ring gripper 142 returns to the irregular ring feeding end to grip the second irregular ring G30. At this time, the first pressure rod 145 moves downward to press the irregular ring G30 into the irregular pad mounting groove, completing the assembly of the irregular ring G30.

[0093] During the assembly of the valve stem G60 and the lower ceramic plate G50, the first adsorption device 166 adsorbs the lower ceramic plate G50 onto the valve stem feeding end of the valve stem feeding device 161 and places it on the upper end of the valve stem G60, engaging with the upper end of the valve stem G60. Then, the fifth gripper 165 grips the valve stem G60 with the lower ceramic plate G50 on its upper end and inserts it into the first oiling device 1620 for oiling. After oiling is completed, the fifth gripper 165 grips the oiled valve stem G60 and inserts it into the valve stem assembly station on the conveying device 111, thus completing the assembly of the valve stem G60 and the lower ceramic plate G50. The upper and lower ceramic plate feeding mechanisms are commonly used devices in this field and will not be described in detail here.

[0097] like Figure 15 As shown, the first unloading mechanism 190 includes a second tilting gripper 191, a fifth rotary cylinder 192, and a thirteenth slide rail 193, wherein:

[0098] The second flipping gripper 191 is horizontally positioned above the unloading station of the material conveying device 111; the end of the second flipping gripper 191 is connected to the fifth rotary cylinder 192; the fifth rotary cylinder 192 is positioned on the vertically arranged thirteenth slide rail 193; the fifteenth cylinder (not marked in the figure) pushes the fifth rotary cylinder 192 to move up and down on the thirteenth slide rail 193;

[0099] During unloading, the second flipping gripper 191 picks up the first semi-finished valve core, flips the first semi-finished valve core 180° from the valve seat fixing hole 1112 and places it on the transfer mechanism 200.

[0100] like Figure 24 , Figure 25 As shown, the second O-ring assembly mechanism 350 includes a second O-ring feeding device, a second O-ring sensor 3511, a second O-ring transfer groove 352, a second transfer pin 353, a first expansion part 354, a second O-ring assembly cylinder 355, a second push sleeve 356, a seventeenth cylinder 357, an eighteenth cylinder 358, a nineteenth cylinder 359, and a fourteenth slide rail 3591, wherein:

[0101] The second O-ring assembly mechanism 350 includes a second O-ring feeding device, a second transfer pin 353, a first spreading part 354, a second O-ring assembly cylinder 355, a second push sleeve 356, a seventeenth cylinder 357, an eighteenth cylinder 358, and a nineteenth cylinder 359; wherein:

[0102] The second O-ring feeding device is provided with a second O-ring feeding groove 352; the structure of the second O-ring feeding groove 352 is the same as that of the first O-ring transfer groove 342; the first supporting part 354 and the second O-ring assembly cylinder 355 are both set on a vertically set slide rail; the movable end of the eighteenth cylinder 358 drives the slider on the slide rail to move up and down, thereby driving the first supporting part 354 and the second O-ring assembly cylinder 355 to move up and down; the eighteenth cylinder 358 is set on the slider of the horizontally set fourteenth slide rail 3591; the movable end of the nineteenth cylinder 359 pushes the slider of the fourteenth slide rail 3591 to move horizontally;

[0103] The bottom of the first support portion 354 is cylindrical, and the diameter of the cylinder is larger than the diameter of the second O-ring G110 in its natural state. The cylindrical sidewall has several notches. The upper sidewall of the second transfer needle 353 has several protruding side plates. The notches in the first support portion 354 can be used to insert the side plates. The diameter of the first support portion 354 is smaller than the diameter formed by the protruding side plates. The bottom of the second O-ring assembly cylinder 355 has a notch that matches the shape of the upper part of the second transfer needle 353. The outer wall of the second O-ring assembly cylinder 355 has a second push sleeve 356. The second push sleeve 356 is connected to the movable end of the seventeenth cylinder 357. The seventeenth cylinder 357 drives the second push sleeve 356 to move in the vertical direction.

[0104] When assembling the second O-ring G110, the first supporting part 354 moves to the feeding end of the second O-ring and inserts into the part assembly slot of the feeding end of the second O-ring. After supporting the second O-ring G110 with the cylindrical part, it moves upward and transfers to above the second transfer pin 353. Then, the first supporting part 354 moves downward, so that the side plate of the second transfer pin 353 inserts into the notch of the cylindrical part of the first supporting part 354. Since the diameter formed by the side plate of the second transfer pin 353 is larger than the diameter of the cylindrical part of the first supporting part 354, the second O-ring G110 is transferred to the second transfer pin 353 during the downward movement of the first supporting part 354. Afterward, the first supporting part 354 returns to its original position. The second O-ring feeding end supports the second O-ring; at this time, the second O-ring assembly cylinder 355 moves above the second transfer needle 353, and the second O-ring assembly cylinder 355 moves downward to the second transfer needle 353, so that the side plate of the second transfer needle 353 enters the notch in the side wall of the second O-ring assembly cylinder 355. Since the diameter of the second O-ring assembly cylinder 355 is slightly larger than the diameter of the second transfer needle 353, when the second O-ring assembly cylinder 355 moves downward, when the second O-ring reaches the bottom of the second transfer needle 353, the bottom of the second O-ring assembly cylinder 355 squeezes into the second O-ring and supports the second O-ring, thereby transferring the second O-ring onto the second O-ring assembly cylinder 355;

[0105] When the first opening part 354 supports the second second O-ring G110 and moves upward, the second O-ring assembly cylinder 355 moves upward accordingly. When the first opening part 354 moves to the second transfer needle 353, the second O-ring assembly cylinder 355 moves to the top of the second semi-finished valve core on the second transfer mechanism 220. When the first opening part 354 moves downward to transfer the second second O-ring to the second transfer needle 353, the second push sleeve 356 of the second O-ring assembly cylinder 355 moves downward to install the first second O-ring on the second semi-finished valve core, forming the finished valve core.

[0106] The second unloading mechanism 360 is a gripper structure. Using grippers to pick up and unload materials is a common technique in this field, and will not be described in detail here.

[0107] like Figure 25 As shown, a detection device 380 is provided on one side of the second O-ring assembly mechanism along the transport direction of the second transfer mechanism. The detection device 380 is used to detect the performance of the finished valve core. The detection device 380 can be an existing valve core detection device, which will not be described in detail here.

[0108] Preferably, defective product frames are provided on one side of the first feeding mechanism 190 and on one side of the second feeding mechanism 360 for collecting defective products.

[0109] In specific implementation, such as Figure 17 As shown, the present invention provides a faucet valve core elastic ring and outer shell assembly mechanism, including a transfer mechanism 200, an insertion mechanism 310, a washer assembly device 320, an outer shell assembly device 330 and a first O-ring assembly device 340.

[0110] The gasket assembly device 320, the housing assembly device 330, and the first O-ring assembly device 340 are sequentially arranged on one side of the transfer mechanism 200. Each of the gasket assembly device 320, the housing assembly device 330, and the first O-ring assembly device 340 is provided with a part assembly slot that matches the shape of the part to be assembled. The part assembly slot is used to place the part to be assembled. The insertion mechanism 310 can drive the first semi-finished valve core to move horizontally between the transfer mechanism 200, the gasket assembly device 320, the housing assembly device 330, and the first O-ring assembly device 340, and to vertically insert the valve core G10 into the part assembly slot to assemble the part.

[0111] During assembly, the ninth gripper of the transfer mechanism 200 moves the first semi-finished valve core sequentially to the parts assembly slots of the gasket assembly device 320, the housing assembly device 330, and the first O-ring assembly device 340. The parts assembly slots contain corresponding parts. The transfer mechanism 200 moves the first semi-finished valve core downward so that it is inserted into each parts assembly slot for the assembly of gasket G80, housing G70, and first O-ring G90. After assembly, the transfer mechanism 200 moves the finished valve core upward and transfers the assembled valve core to the material or to the transfer mechanism 200. The transfer mechanism 200 then continues to transfer the finished valve core to the next process.

[0112] The faucet valve core elastic ring and housing assembly mechanism provided in this embodiment drives the first semi-finished valve core to move horizontally between the gasket assembly device, the housing assembly device and the first O-ring assembly device through the transfer mechanism, and inserts the first semi-finished valve core into the corresponding part mounting slot for gasket, housing and first O-ring assembly. The process steps are simple and the installation speed of each part is fast, which improves the assembly efficiency of gasket, housing and first O-ring assembly.

[0114] The swing arm 313 drives the ninth gripper 311 to move horizontally between the transfer mechanism 200, the washer assembly device 320, the outer shell assembly device 330 and the first O-ring assembly device 340.

[0115] The lifting cylinder 314 drives the ninth gripper 311 to move vertically on the transfer mechanism 200, the washer assembly device 320, the outer shell assembly device 330 and the first O-ring assembly device 340, thereby inserting or pulling the first semi-finished valve core G10 into or out of the parts assembly slot.

[0116] This embodiment provides a valve insertion mechanism structure, which realizes the purpose of driving the first semi-finished valve core to move in various parts assembly devices and insert into the parts assembly slot for parts assembly, with a wide range of movement.

[0121] The structure of the first O-ring transfer groove 342 is the same as that of the first mounting groove 322 and the second mounting groove 323. Alternatively, the bottom of the first O-ring transfer groove 342 may have a groove that matches the shape of the bottom of the first O-ring transfer pin 312, so that the first O-ring transfer pin 312 can be inserted into the first O-ring transfer groove 342. The side wall of the first O-ring assembly cylinder 345 may have several notches that match the shape of the bottom of the first O-ring transfer pin 312, providing a certain deformation space for the first O-ring assembly cylinder 345. Furthermore, the bottom side plate of the first O-ring assembly cylinder 345 is stepped, and the diameter of the first O-ring assembly cylinder 345 is slightly larger than that of the bottom side plate of the first O-ring transfer pin 312. The diameter of the lower step is smaller than the diameter of the upper step formed by the bottom side plate of the first O-ring transfer needle 312. When the lower step of the first O-ring transfer needle 312 drives the first O-ring G90 to insert into the inner wall of the first O-ring assembly cylinder 345, the outer wall of the first O-ring assembly cylinder 345 will open the first O-ring G90, thereby achieving the purpose of transferring the first O-ring group G30 onto the first O-ring assembly cylinder 345. The outer wall of the first O-ring assembly cylinder 345 is provided with a first push sleeve 346. The first push sleeve 346 is connected to the movable rod of the sixteenth cylinder 347. The first push sleeve 346 can move up and down along the first O-ring assembly cylinder 345 under the drive of the sixteenth cylinder 347.

The second oiling device 370 consists of upper and lower parts; the upper and lower parts enclose an oiling channel 371; an oiling through hole 372 is provided on the side wall of the oiling channel 371 near the valve stem oiling groove; an oil injection hole 373 is provided on the side wall of the oiling channel 371 away from the valve stem oiling groove; an oil injection machine is connected to the oil injection hole 373; the oil injection machine injects oil into the oiling channel 371 through the oil injection hole 373. Grease from the oiling channel 371 is applied to the valve stem surface via the oiling through-hole 372. The second oiling device 370 is used to apply oil to the first semi-finished valve core G10. Placing the second oiling device 370 on a bracket at the bottom of the housing mounting end 332 saves on bracket mounting parts and allows it to be positioned around the housing mounting end 332, facilitating oiling of the first semi-finished valve core G10 before assembly. In this embodiment, since the assembly mechanism provided by the present invention uses insertion-type assembly, excessive frictional resistance between the first semi-finished valve core and the parts can easily affect the installation effect. This embodiment, through the design of the second oiling device, allows oiling of the first semi-finished valve core G10 before assembly, thereby reducing the frictional resistance between the first semi-finished valve core G10 and the parts, improving the quality and efficiency of parts assembly, and reducing the defect rate.

[0131] Furthermore, it also includes a drip-proof box; the drip-proof box is located below the second oiling device 370. In practice, the second oiling device 370 may overflow during use. The drip-proof box can prevent the overflowing oil from dripping onto the ground, thereby reducing the floor cleaning work for workers and preventing slips.

[0132] The above-mentioned feeding devices are all commonly used equipment in this field, and will not be described in detail here.

[0133] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
