Description

Technical Field

[0001] This utility model relates to the technical field of valve spring assembly, and in particular to an automatic valve spring assembly device and its automatic feeding assembly device. Background Technology

[0002] The assembly structure of valves and springs is used in fluid control, mechanical transmission, and pressure regulation. Valves (such as valves, solenoid valves, and check valves) are usually key components for opening, closing, or regulating fluid passages, while springs provide restoring force, maintain sealing pressure, or buffer mechanical vibrations. The spring needs to be fitted onto one end of the valve while preventing the valve from falling off. After the spring and valve are assembled, they are placed in the assembly position on the product, thus completing the assembly of the spring and valve.

[0003] (The difficulty of automating the assembly of valves and springs into products is analyzed below:)

[0004] 1. The spring needs to be fitted onto the valve. There are unstable factors in the fitting process. The spring may be compressed and deformed or twisted. How to overcome this is a difficult problem.

[0005] 2. After assembling the spring and valve, how to clamp them into the assembly position on the product while avoiding factors that might cause spring instability;

[0006] Currently, there are no automated assembly devices for assembling valves and springs onto products. Valve and spring assembly is still done manually, which has the disadvantages of low assembly efficiency and high labor intensity. Utility Model Content

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model uses a transfer component of the assembly mechanism to move the assembly component to the spring placement station. The clamping cylinder of the clamping component of the assembly component drives a pair of clamps to close, thereby clamping the spring onto the clamping hole. The transfer component then moves the clamping component to the top of the valve placement station. The ejection cylinder of the ejection mechanism drives the ejection rod to pass through the ejection hole, thereby fitting the valve onto the spring. This ensures the assembly of the valve and the spring. During this process, the spring assembly is relatively stable and will not deform or twist, which would lead to unsuccessful assembly.

[0022] 2. After the clamping component of this utility model clamps the spring and the valve, the transfer component of the assembly mechanism moves the assembly component to the product assembly position. Then, the push cylinder of the push component of the assembly component drives the push rod to push the spring located on the clamping hole into the product assembly position. At the same time, the transfer component slowly rises to prevent the assembled spring from flying out of the product, thus ensuring that the valve and the spring are stably assembled on the product.

[0023] 3. The present invention provides an automatic assembly device for valve springs and an automatic feeding and assembly device thereof. The spring feeding device feeds the springs, the valve feeding device feeds the valves, and the valve spring individual feeding device feeds individual springs to the spring placement station and individual valves to the valve placement station. Then, the automatic assembly device assembles the springs and valves and then assembles them onto the product. It realizes the function of automating the assembly of springs and valves and assembling them onto the product, and has the advantages of high production efficiency and greatly reducing the intensity of manual labor.

[0059] The valve feeding device 2 includes a valve vibrating plate 21 and a linear vibrator 22 installed at one end of the valve vibrating plate 21. The linear vibrator 22 is installed at one end of the valve spring single feeding device 3.

[0060] The working principle of the automatic valve spring feeding and assembly device of Embodiment 2 of this utility model is as follows:

[0061] S1: First, the feeding cylinder 32 of the valve spring single feeding device 3 drives the feeding slider 33, so that the feeding slider 33 comes to the valve inlet 310 and the side of the first detection sensor 36, so that the valve placement groove 35 on the feeding slider 33 corresponds to the valve inlet 310, and the spring placement groove 34 is located directly below the feeding conveyor block 1342 of the spring feeding device 1.

[0062] S2: The valve feeding device 2 starts feeding. The valve vibrating plate 21 vibrates the valve 8 onto the linear vibrator 22. The feeding port at one end of the linear vibrator 22 is connected to the valve inlet 310. At this time, the valve inlet 310 is connected to the valve placement groove 35 (the groove shape of the valve placement groove 35 is only for a single valve 8 to be placed). Therefore, the linear vibrator 22 feeds a single valve 8 onto the valve placement groove 35.

[0063] S3: The spring feeding device 1 starts feeding, which includes the following sub-steps:

[0064] S31: The spring vibrating plate 11 feeds the spring 9 onto the first feeding pipe 110, and the spring 9 of the first feeding pipe 110 is sent to the receiving block 123 of the feeding and storage mechanism 12.

[0065] S32: The material handling and storage mechanism 12 begins to perform material handling and storage, which also includes the following sub-steps:

[0066] S321: Initially, the first switch drive cylinder 1251 of the first switch assembly 125 drives the first switch stop block 1252 to block the receiving pipe 124, so that the receiving pipe 124 cannot drop the spring 9 onto the spring feeding mechanism 13.

[0067] S322: At this time, the material storage mechanism 12 begins to store material. In this embodiment, there are three storage holes 1263, and three detection sensors are inserted at one end of the corresponding slide block 122 to detect whether the storage hole 1263 contains the spring 9 and to perform logic control on the storage (the program content of this logic control is prior art and will not be described here). The operating principle of the material storage mechanism 12 starting to store material is as follows:

[0068] Initially, the storage slider 1262 is located at the starting end. At this time, the first storage hole 1263 of the storage slider 1262 corresponds to the receiving block 123. After the first storage hole 1263 stores material in the first spring 9;

[0069] Next, the stroke blocking cylinder 1271 of the stroke blocking assembly 127 pushes the blocking block 1272 into one side of the storage slider 1262. Since the connection between the storage slider 1262 and the storage drive cylinder 1261 is wider than the storage slider 1262, when the storage drive cylinder 1261 drives the storage slider 1262 to slide forward a certain distance, the connection between the two will be blocked by the blocking block 1272. At this time, the second storage hole 1263 of the storage slider 1262 corresponds to the receiving block 123. After the second storage hole 1263 stores material for the second spring 9;

[0070] Next, the stroke blocking cylinder 1271 of the stroke blocking assembly 127 pushes the blocking block 1272 away from the side of the storage slider 1262. At this time, the storage driving cylinder 1261 drives the storage slider 1262 to slide forward to the farthest distance. At this time, the third storage hole 1263 of the storage slider 1262 corresponds to the receiving block 123. After the third storage hole 1263 stores material for the third spring 9, the material storage mechanism 12 completes the storage action. At this time, the storage driving cylinder 1261 drives the storage slider 1262 to reset to the starting end, waiting for the spring 9 to feed material.

[0071] S323: When it is necessary to feed spring 9, the first switch drive cylinder 1251 of the first switch assembly 125 drives the first switch stop 1252 to open the receiving pipe 124, so that the first switch hole 12520 is aligned with the receiving pipe 124. With the same action as S322, the storage drive cylinder 1261 sequentially lowers the spring 9 on the three storage holes 1263 onto the receiving pipe 124.

[0072] The purpose of the material feeding mechanism 12 is twofold: firstly, it serves as a material storage mechanism to facilitate feeding of the spring 9; secondly, its mechanical structure is connected to the spring vibrating plate 11, but separated from the valve spring single feeding device 3, thereby preventing the vibration of the spring vibrating plate 11 from affecting the stability of the valve spring single feeding device 3.

[0073] S33: When the receiving pipe 124 feeds the spring 9, the feeding block 132 cooperates with and is connected to the receiving pipe 124. At this time, the spring 9 falls onto the feeding block 132, and the spring 9 of the feeding block 132 flows into the second feeding pipe 133. The spring 9 of the second feeding pipe 133 flows into the feeding trough 13420 of the feeding conveying block 1342.

[0074] The lifting conveying cylinder 1341 of the feeding conveying assembly 134 drives the feeding conveying block 1342 to descend to the top of the spring placement groove 34. Then, the second switch driving cylinder 13431 of the second switch assembly 1343 drives the second switch stop block 13432 to open the feeding groove 13420 of the feeding conveying block 1342, so that the spring 9 flows into the spring placement groove 34. Then the lifting driving cylinder drives the feeding conveying block 1342 to return to its original position.

[0075] S4: After the first detection sensor 36 of the valve spring single feeding device 3 senses the spring 9, the feeding cylinder 32 drives the feeding slider 33 to slide along the feeding track 31 to one end of the feeding track 31. At this time, the spring placement groove 34 comes to the spring placement station 41, the second detection sensor 37 detects the spring 9, the valve placement groove 35 comes to the valve placement station 42, the second detection sensor 37 detects the valve 8, and the ejection hole 420 is opened at the bottom of the valve placement station 42.

[0076] S5: An automatic valve spring assembly device 4 begins the assembly operation, which includes the following sub-steps:

[0077] S51: Assemble the spring 9 with the valve 8:

[0078] The clamping component 4321 of the assembly component 432 is quickly moved above the spring placement station 41 by the y-axis drive module 4311, the primary z-axis drive module 4312 and the x-axis drive module 4314 of the transfer component 431. The secondary z-axis drive module 4313 makes the grippers 43212 of the clamping component 4321 located on both sides of the spring 9. Then, the clamping cylinder 43211 of the clamping component 4321 drives the grippers 43212 to grab the spring 9, so that the spring 9 is located on the clamping hole 43213.

[0079] The spring 9 held by the clamping assembly 4321 is positioned at the top of the valve placement station 42 by the y-axis drive module 4311, the primary z-axis drive module 4312, the secondary z-axis drive module 4313 and the x-axis drive module 4314. The ejection cylinder 442 of the ejection mechanism 44 drives the ejection rod 443 to rise and eject the valve rod, thereby assembling the valve rod onto the spring 9.

[0080] S51: Assemble the assembled spring 9 and valve 8 onto the product:

[0081] By using the y-axis drive module 4311, primary z-axis drive module 4312, secondary z-axis drive module 4313, and x-axis drive module 4314 of the transfer component 431, the clamping component 4321 is brought to the top of the product. At this time, the ejection component 4322 drives the push rod 43223 downward to push the assembled spring 9 and valve 8 onto the product. Simultaneously, the secondary z-axis drive module 4313 slowly rises to prevent the spring 9 from being excessively compressed and popping out of the product during the pushing process.

[0082] The advantages of the automatic valve spring feeding and assembly device of Embodiment 2 of this utility model are as follows: the spring feeding device 1 can feed springs 9 individually and store springs 9, thereby improving the feeding speed of springs 9; the valve spring individual feeding device 3 accurately feeds valve parts 8 and springs 9 individually; and finally, the automatic valve spring assembly device 4 assembles springs 9 and valve parts 8 and then assembles them onto the product. It realizes the function of automatically assembling springs 9 and valve parts 8 and assembling them onto the product, and has the advantages of stable assembly, high assembly accuracy, high production efficiency, and greatly reduced manual labor intensity.

[0083] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
