Description

Technical Field

[0001] The present invention relates to the technical field of valve assembly, in particular to a lock valve assembly machine. Background Art

[0002] Existing locking valves are usually composed of a valve body, valve stem, valve ball, valve cover, magnet, positioning rod, lock cap, pin, etc. The magnets are a group, repel each other, and penetrate the valve stem and valve body. Only by using a special key to push the magnet out of the valve body can the opening and closing operation be achieved, thereby limiting the use of the locking valve and meeting the needs of standardized operation or unified management.

[0003] At present, locking valves usually need to be equipped with magnets, positioning rods, pins and other accessories to ensure the locking function. This requires the processing of corresponding small holes on the valve body and valve stem. The holes on the valve stem and the valve body must be coaxial, and the relative positions of several groups of holes have angle requirements. This places high demands on the processing accuracy of the valve body and valve stem.

[0004] Furthermore, the lockshield's magnets, positioning rods, and pins are relatively small, typically 3-4mm in diameter. Installing these components into their corresponding small holes places high demands on the assembler, requiring both skilled and meticulous work, resulting in low assembly efficiency. The lockshield's magnets must be installed in a repelling state to achieve the locking function. Manual assembly can result in reverse installation, resulting in defective products and a low pass rate.

[0005] In view of this, this application is hereby filed. Summary of the Invention

[0070] Example

[0071] This embodiment provides a locking valve assembly machine 100, the assembly process of the locking valve assembly machine 100 is as follows: Figure 1 As indicated by the arrow.

[0072] The locking valve assembly machine 100 includes a guide rail 2, a work station fixture 13, and a valve body feeding device 3, a valve body clamping device 4, a valve stem assembly device 5, a valve ball assembly device 6, a valve cover assembly device 7, a magnet assembly device 8, a positioning rod assembly device 9, a lock cap assembly device 10, a pin assembly device 11 and a locking valve unloading device 12 arranged in sequence along the guide rail 2.

[0073] The guide rail 2 is used to be laid on the workbench 1. For reference, the guide rail 2 may include two rails arranged at intervals, so as to achieve stable operation of the station fixture 13.

[0074] The valve body feeding device 3 is used to receive valve bodies 210 to be assembled. When there are multiple valve bodies 210 to be assembled, the multiple valve bodies 210 to be assembled are sequentially arranged in the valve body feeding device 3. The valve body clamping device 4 is used to clamp the valve bodies 210 sequentially output from the valve body feeding device 3; the valve stem assembly device 5 is used to assemble the valve stem 220 on the valve body 210; the valve ball assembly device 6 is used to assemble the valve ball on the valve body 210; the valve cover assembly device 7 is used to assemble the valve cover on the valve body 210; the magnet assembly device 8 is used to assemble the magnet 230 on the valve body 210; the positioning rod assembly device 9 is used to assemble the positioning rod on the valve body 210; the locking cap assembly device 10 is used to assemble the locking cap 240 on the valve body 210; the pin assembly device 11 is used to assemble the pins on the valve body 210 to form the lock valve 200; and the lock valve unloading device 12 is used to unload the lock valve 200.

[0075] The work station fixture 13 is arranged on the guide rail 2 and is used to move along the extension direction of the guide rail 2 during the assembly process of the locking valve 200 so as to assemble the valve body 210 output from the valve body clamping device 4 in sequence through the valve stem assembly device 5, the valve ball assembly device 6, the valve cover assembly device 7, the magnet assembly device 8, the positioning rod assembly device 9, the lock cap assembly device 10, the pin assembly device 11 and the locking valve unloading device 12, and further, it can circulate to the work station corresponding to the valve body clamping device 4.

[0076] In addition, a vibrating material tray 50 may be provided on the workbench 1 to realize sequential conveyance of the valve stems 220 , thereby feeding the valve stem assembly device 5 .

[0077] Please continue to combine Figure 1 The assembly process of the lock valve assembly machine 100 provided in this application includes the following:

[0078] Station fixture 13 along Figure 1The assembly process in the process circulates on the guide rail 2. The valve body feeding device 3 receives several valve bodies 210 arranged in sequence from the outside (the case of only one valve body 210 is not excluded). Under the clamping action of the valve body clamping device 4, the valve bodies 210 are removed in order and placed on the work station fixture 13. The work station fixture 13 loads the valve body 210 and passes through the corresponding work stations of the valve stem assembly device 5, valve ball assembly device 6, valve cover assembly device 7, magnet assembly device 8, positioning rod assembly device 9, lock cap assembly device 10, pin assembly device 11, and lock valve unloading device 12 in sequence, finally completing the assembly of the lock valve 200. Subsequently, the work station fixture 13 returns to the work station where it receives the valve body 210 from the valve body clamping device 4, thus completing one cycle.

[0079] Please refer to Figure 2 The locking valve 200 includes a valve body 210, a valve stem 220, a magnet 230, and a locking cap 240. The valve stem 220, the locking cap 240, and the pair of magnets 230 are correspondingly mounted on the valve body 210. Under normal circumstances, the pair of magnets 230 are in a repulsive state, thereby achieving a locking function.

[0080] Please combine Figures 3 to 15 It should be noted that for ease of description, the following description introduces certain relative displacement directions, such as "vertical," "lateral," or "horizontal movement," which are all relative directions that are understandable to those skilled in the art. Furthermore, the various power sources mentioned below, such as those for lifting or translation, can be pneumatic cylinders, hydraulic cylinders, or electric cylinders, and those for rotation can be electric motors or pneumatic motors.

[0081] Please refer to Figure 3 and Figure 4 The valve body feeding device 3 includes a feeding rack 31 , a first power source 32 , a second power source 33 , a first feeding fixture 34 , a third power source 35 , a fourth power source 36 and a second feeding fixture 37 .

[0082] The feeding rack 31 is disposed on the workbench 1 , and the feeding rack 31 has a valve body conveying channel 310 for conveying the valve bodies 210 to be assembled.

[0083] The first power source 32 is provided on the workbench 1, and the second power source 33 is provided on the first power source 32 and is used to achieve vertical movement under the drive of the first power source 32. Similarly, the third power source 35 is provided on the workbench 1, and the fourth power source 36 is provided on the third power source 35 and is used to achieve vertical movement under the drive of the third power source 35.

[0084] The first feeding fixture 34 is provided at the second power source 33 and is used to realize lateral movement under the drive of the second power source 33. Similarly, the second feeding fixture 37 is provided at the fourth power source 36 and is used to realize lateral movement under the drive of the fourth power source 36.

[0085] The above-mentioned first feeding clamp 34 and second feeding clamp 37 are arranged opposite to each other at the output port of the feeding rack 31, and are respectively driven by the second power source 33 and the fourth power source 36 to approach or move away from each other to clamp or release the valve body 210 output from the feeding rack 31, and are driven by the first power source 32 and the third power source 35 to approach or move away from the valve body clamping device 4 to transport or reset the valve body 210.

[0086] In the present application, the top of the valve body conveying channel 310 is open so that the valve body 210 can be kept in a vertical state. Preferably, the valve body conveying channel 310 is designed according to the cross-sectional profile of the valve body 210, with a small top and a large bottom, so as to keep the valve body 210 in a vertical state for conveying. When the valve body 210 is conveyed to the tail end of the feeding rack 31, it immediately falls between the first feeding clamp 34 and the second feeding clamp 37 under the action of gravity. The two clamps are clamped under the action of the second power source 33 and the fourth power source 36, and are driven by the first power source 32 and the third power source 35 to rise to the corresponding clamping position of the valve body clamping device 4. After the valve body 210 is taken away by the valve body clamping device 4, the first power source 32 and the third power source 35 drive the valve body 210 to descend in height, so that the first feeding clamp 34 and the second feeding clamp 37 are reset to the tail end of the feeding rack 31.

[0087] Please refer to Figure 5 The valve body clamping device 4 includes a fifth power source 41 , a sixth power source 42 , a seventh power source 43 and a clamping fixture 44 .

[0088] A fifth power source 41 is provided on the workbench 1 , a sixth power source 42 is provided on the fifth power source 41 and is driven by the fifth power source 41 to achieve vertical rotation, and a seventh power source 43 is provided on the sixth power source 42 and is driven by the sixth power source 42 to achieve vertical movement. A gripping fixture 44 is provided on the seventh power source 43 and is driven by the seventh power source 43 to grip and transfer the valve body 210 output from the valve body feeding device 3 to the workstation fixture 13 .

[0089] When the valve body 210 reaches the corresponding clamping position, the seventh power source 43 is lowered to the clamping position under the drive of the sixth power source 42. At the same time, the clamping fixture 44 is driven by the seventh power source 43 to clamp the valve body 210. Through the rotation of the fifth power source 41, the valve body 210 is transferred to the station fixture 13. The provision of the fifth power source 41, the sixth power source 42, and the seventh power source 43 can achieve stable transportation of the valve body 210.

[0090] Please refer to Figure 6 The workstation fixture 13 includes a base plate 131 , a first workstation power source 132 , a second workstation power source 133 , a first fixture block 134 and a second fixture block 135 .

[0091] The bottom plate 131 is disposed on the guide rail 2 and is used to move along the extending direction of the guide rail 2 during the assembly process of the lock valve 200 .

[0092] The first station power source 132 and the second station power source 133 are both disposed on the base plate 131. The first clamp block 134 and the second clamp block 135 are respectively disposed on the first station power source 132 and the second station power source 133 and are configured to move closer to each other (corresponding to clamping the valve body 210) or farther away from each other (corresponding to releasing the valve body 210) under the drive of the first station power source 132 and the second station power source 133.

[0093] Furthermore, the workstation fixture 13 further includes a first auxiliary magnetic pole 136 and a second auxiliary magnetic pole 137 . The first auxiliary magnetic pole 136 and the second auxiliary magnetic pole 137 are respectively disposed opposite to the first fixture block 134 and the second fixture block 135 .

[0094] The provision of auxiliary magnetic poles ensures that the magnets 230 will not repel each other and fall off after subsequent assembly. Preferably, the first and second auxiliary magnetic poles 136 and 137 are highly magnetic, with the same polarity as the magnets 230 installed within the valve body 210, to ensure that the magnets 230 will not fall off after being installed within the valve body 210. Furthermore, the auxiliary magnetic poles can detect whether the positive and negative poles of the magnets 230 are correctly installed. If the magnets 230 are installed incorrectly, they will be attracted by the strong magnets, preventing them from being scrapped.

[0095] Please refer to Figure 7 The valve stem assembly device 5 includes an eighth power source 51, a ninth power source 52, and a valve stem chuck 53. The eighth power source 51 is disposed on the workbench 1, and the ninth power source 52 is disposed on the eighth power source 51 and is configured to move vertically under the drive of the eighth power source 51; the valve stem chuck 53 is disposed on the ninth power source 52 and is configured to move horizontally under the drive of the ninth power source 52; the valve stem chuck 53 is configured to clamp or release the valve stem 220.

[0096] The valve stem chuck 53 can first clamp the valve stem 220 output from the vibrating material disk 50. When the work station fixture 13 carries the valve body 210 to the work station corresponding to the valve stem assembly device 5, the valve stem chuck 53 approaches the valve body 210 under the drive of the ninth power source 52. After reaching the installation position, the valve stem 220 is installed into the valve body 210 (the valve stem 220 hole of the valve body 210) under the drive of the eighth power source 51. Since the O-ring on the valve stem 220 is compressed, the valve stem 220 can stay in the valve body 210.

[0097] After the valve stem 220 is assembled, the workstation fixture 13 continues to be transported to the workstation corresponding to the valve ball assembly device 6.

[0098] Please refer to Figure 8 The valve ball assembly device 6 includes a tenth power source 61 , an eleventh power source 62 , a twelfth power source 63 and a valve ball chuck 64 .

[0099] The tenth power source 61 is arranged on the workbench 1, the eleventh power source 62 is arranged on the tenth power source 61 and is used to move vertically under the drive of the tenth power source 61; the twelfth power source 63 is arranged on the eleventh power source 62 and is used to move laterally under the drive of the eleventh power source 62; the valve ball clamp 64 is arranged on the twelfth power source 63 and is used to clamp or release the valve ball under the drive of the twelfth power source 63.

[0100] The valve ball clamp 64 can first clamp the valve ball and push it into the valve body 210 for installation under the drive of the tenth power source 61, the eleventh power source 62 and the twelfth power source 63. The tenth power source 61, the eleventh power source 62 and the twelfth power source 63 can facilitate the movement of the valve ball up, down, left and right, making it easier to align and assemble.

[0101] After the valve ball is assembled, the workstation fixture 13 is transported to the workstation corresponding to the valve cover assembly device 7 .

[0102] Please refer to Figure 9 The valve cover assembly device 7 includes a thirteenth power source 71 , a fourteenth power source 72 , a fifteenth power source 73 , a gear box 74 , a sixteenth power source 75 and a valve cover clamp 76 .

[0103] The thirteenth power source 71 is provided on the workbench 1, the fourteenth power source 72 is provided on the thirteenth power source 71 and is used for vertical movement under the drive of the thirteenth power source 71; the fifteenth power source 73 is provided on the fourteenth power source 72 and is used for horizontal movement under the drive of the fourteenth power source 72. The gear box 74 is provided on the fifteenth power source 73 and is used for horizontal movement under the drive of the fifteenth power source 73.

[0104] The sixteenth power source 75 is disposed in the gear box 74 and is connected to the valve cover clamp 76 through the gear box 74 . The valve cover clamp 76 is used to install the valve cover into the valve body 210 .

[0105] The above-mentioned thirteenth power source 71, fourteenth power source 72, fifteenth power source 73 and sixteenth power source 75 are used to control the movement of the valve cover clamp 76 to facilitate alignment and assembly. The presence of the gear box 74 can increase the torque, thereby realizing the rotation of the valve cover into the valve body 210.

[0106] After the valve cover is assembled, the station fixture 13 is transported to the station corresponding to the magnet assembly device 8 .

[0107] Typically, the magnet 230 needs to be screened to achieve certainty in the direction of the magnetic poles.

[0108] Please refer to Figure 10 The lock valve assembly machine 100 further includes a magnet screening device 14 , and the magnet screening device 14 includes a magnet channel 141 , a third auxiliary magnetic pole 142 , and a fourth auxiliary magnetic pole 143 .

[0109] A magnet channel 141 is provided on the workbench 1 for the horizontal passage of the magnet 230. A leakage hole 1411 is provided in the magnet channel 141. A third auxiliary magnetic pole 142 is provided on one side of the magnet channel 141, corresponding to the leakage hole 1411. It acts on magnets 230 that are misaligned, forcing them toward the leakage hole 1411. A fourth auxiliary magnetic pole 143 is spaced below the third auxiliary magnetic pole 142 to assist the magnet 230 in filtering out leakage.

[0110] In the present application, the magnet channel 141 is flat, and the magnet 230 passes horizontally through the magnet channel 141. A third auxiliary magnetic pole 142 is provided on one side of the channel. When the direction of the magnet 230 is not consistent, it acts with the third auxiliary magnetic pole 142 and moves into the leakage hole 1411. Under the action of the vibration disk, the gravity of the magnet 230 and the fourth auxiliary magnetic pole 143, the magnet 230 that does not conform to the direction is screened out, thereby facilitating the magnet assembly device 8 to take the magnet 230 that meets the requirements.

[0111] Please refer to Figure 11 and Figure 12 The magnet assembly device 8 includes a seventeenth power source 81 , an eighteenth power source 82 , a nineteenth power source 83 , a carrier 84 , a first drilling rig 85 , a second drilling rig 86 , a first manipulator 87 and a second manipulator 88 .

[0112] The seventeenth power source 81 is arranged on the workbench 1, the eighteenth power source 82 is arranged on the seventeenth power source 81 and is used for vertical movement under the drive of the seventeenth power source 81; the nineteenth power source 83 is arranged on the eighteenth power source 82 and is used for horizontal movement under the drive of the eighteenth power source 82; the carrier 84 is arranged on the nineteenth power source 83 and is used for horizontal movement under the drive of the nineteenth power source 83.

[0113] The first drill 85 and the second drill 86 are distributed at 180 degrees on the carrier 84 and are used to drill holes in the valve body 210. The first manipulator 87 and the second manipulator 88 are both set on the carrier 84 to clamp the magnet 230 output from the magnet screening device 14 and install it into the valve body 210.

[0114] The seventeenth power source 81 , the eighteenth power source 82 , the nineteenth power source 83 and the like can enable the first drilling rig 85 and the second drilling rig 86 to move in up, down, left, and right directions, thereby facilitating alignment. Figure 12 In the figure, the first drilling rig 85 and the second drilling rig 86 are distributed up and down, thereby drilling holes on opposite sides of the valve body 210. After the drilling is completed, the first manipulator 87 and the second manipulator 88 clamp the magnet 230 output from the magnet screening device 14 and assemble it to the valve body 210.

[0115] The positioning rod can also be assembled at the same workstation. Specifically, in this embodiment, the positioning rod assembly device 9 includes a third drilling rig 91 , a fourth drilling rig 92 and a third manipulator 93 .

[0116] The third drilling rig 91 and the fourth drilling rig 92 are distributed at 90° on the carrier 84 and symmetrically distributed between the first drilling rig 85 and the second drilling rig 86. The third drilling rig 91 and the fourth drilling rig 92 are used to drill holes in the valve body 210, and the third manipulator 93 is used to clamp the positioning rod and install it into the valve body 210.

[0117] The third and fourth drilling rigs 91 and 92 drill corresponding holes in the valve body 210. After drilling is complete, the third manipulator 93 grips the positioning rod and installs it into the valve body 210. The first and third drilling rigs 85 and 91 are arranged at a 45-degree angle, and the fourth and second drilling rigs 92 and 86 are also arranged at a 45-degree angle. Because the third and fourth drilling rigs 91 and 92 are already set at a 90-degree angle, the opening and closing angle of the lockshield valve 200 is ensured to be exactly 90 degrees, further improving the product qualification rate. Because the first, second, third, and fourth drilling rigs 85, 86, 91, 92, first and second manipulators 87, 88, and third manipulators 93 are all integrated, they can be processed simultaneously and at the same station, further improving efficiency and accuracy. Furthermore, the first and second drilling rigs 85 and 86 are arranged at a 180-degree angle, ensuring that the assembled pair of magnets 230 are aligned at a 180-degree angle, ensuring product stability.

[0118] After the magnet 230 and the positioning rod are assembled, the station fixture 13 continues to be transported to reach the station corresponding to the lock cap assembly device 10.

[0119] Please refer to Figure 13 The locking cap assembly device 10 includes a twentieth power source 101 , a twenty-first power source 102 , a twenty-second power source 103 , a twenty-third power source 104 and a locking cap chuck 105 .

[0120] The twentieth power source 101 is arranged on the workbench 1, the twenty-first power source 102 is arranged on the twentieth power source 101 and is used for vertical movement under the drive of the twentieth power source 101; the twenty-second power source 103 is arranged on the twenty-first power source 102 and is used for horizontal movement under the drive of the twenty-first power source 102; the twenty-third power source 104 is arranged on the twenty-second power source 103 and is used for vertical movement under the drive of the twenty-first power source 102; the locking cap chuck 105 is arranged on the twenty-third power source 104 and is used for clamping or releasing the locking cap 240 under the drive of the twenty-third power source 104.

[0121] The lock cap chuck 105 can be aligned through the twentieth power source 101 , the twenty-first power source 102 , the twenty-second power source 103 , the twenty-third power source 104 , etc. The lock cap chuck 105 clamps the lock cap 240 and is assembled to the valve body 210 accordingly.

[0122] After the lock cap 240 is assembled, the pin is assembled immediately. Since the lock cap 240 and the pin are assembled at the same station, the assembly station does not move during the entire process, ensuring the assembly qualification rate.

[0123] Please refer to Figure 14 The pin assembly device 11 includes a fifth drilling machine 111 and a fourth manipulator 112. The fifth drilling machine 111 is set on the workbench 1 and is used to drill holes in the valve body 210; the fourth manipulator 112 is used to clamp the pin and install it into the valve body 210.

[0124] The fifth drilling machine 111 drills a hole in the valve body 210 to form a pin hole. The fourth manipulator 112 clamps the pin and transfers it into the valve body 210 .

[0125] The first drilling rig 85 , the second drilling rig 86 , the third drilling rig 91 , the fourth drilling rig 92 and the fifth drilling rig 111 mentioned above may all adopt a structure in which a motor drives the drill bit to rotate.

[0126] After the locking cap 240 and the pin are assembled, the material can be discharged through the locking valve discharge device 12.

[0127] Please refer to Figure 15The lock valve unloading device 12 includes a twenty-fourth power source 121, a twenty-fifth power source 122, a twenty-sixth power source 123, and a unloading fixture 124. The twenty-fourth power source 121 is disposed on the workbench 1, the twenty-fifth power source 122 is disposed on the twenty-fourth power source 121 and is driven by the twenty-fourth power source 121 to move vertically; the twenty-sixth power source 123 is disposed on the twenty-fifth power source 122 and is driven by the twenty-fifth power source 122 to move horizontally; and the unloading fixture 124 is disposed on the twenty-sixth power source 123 and is driven by the twenty-sixth power source 123 to unload the assembled lock valve 200.

[0128] The position of the unloading fixture 124 can be adjusted using the twenty-fourth and twenty-fifth power sources 121 and 122. The twenty-sixth power source 123 drives the unloading fixture 124 to clamp the lock valve 200 and transfer it to the unloading station, completing the unloading process. The unloaded lock valve 200 can then be pushed onto the finished product conveyor for outward transport. When the lock valve 200 is released from the station fixture 13, i.e., separated from the first auxiliary magnetic pole 136 and the second auxiliary magnetic pole 137, the pair of magnets 230 within the valve body 210 repel each other and move in opposite directions, thereby locking the lock valve 200.

[0129] Based on the above, the lockshield valve assembly machine 100 provided by the present application has at least the following advantages:

[0130] (1) By rationally arranging the assembly stations of parts, the continuous automatic assembly of the lock valve 200 and the multi-step assembly at the same station are realized, thereby solving the problem of processing accuracy and improving the assembly efficiency and qualification rate.

[0131] (2) The valve stem 220, valve ball, valve cover and magnet 230 can all be fed by vibration feeding, which is convenient for clamping by the corresponding device.

[0132] (3) Almost all assembly steps are performed on the workstation fixture 13, which improves consistency and assembly accuracy.

[0133] (4) A PLC control system can be designed to make the entire assembly process fully automatic in order to improve efficiency.

[0134] (5) The processing of the magnet 230 hole, the processing of the positioning rod hole, the assembly of the magnet 230, the assembly of the positioning rod, etc. are all completed in the same step. The full combination of processing and assembly ensures the coaxiality of the hole and the installed accessories, which can effectively improve the product qualification rate.

[0135] (6) The assembly of the lock cap 240, the pin hole processing, and the pin assembly are all performed at the same workstation, which reduces the assembly difficulty and improves the assembly accuracy.

[0136] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
