Description

Technical Field

[0001] This application relates to the field of material feeding technology, specifically to an automatic O-ring feeding device. Background Technology

[0002] Pressure sensors are used to measure the pressure of a medium or environment. They require a tight seal at the interface to prevent leakage, and electronic components must be isolated from the medium or environment to prevent corrosion. Many other products also require a certain level of sealing. Using O-rings is often a highly effective method. O-rings require specialized equipment for loading and assembly with other components. Because O-rings are flexible, unlike typical workpieces, they are not easily loaded using conventional methods.

[0003] The statements in this section are provided only as background information in relation to this application and may not constitute prior art. Summary of the Invention

[0034] like Figure 1 As shown, the automatic O-ring feeding device of this application includes at least a vibrating feeding plate 3, a top feeding mechanism 1, a transfer mechanism 2, and a first unloading mechanism 25. The top feeding mechanism 1 receives the O-rings fed by the corresponding vibrating feeding plate 3 in a horizontal orientation (with the O-rings on a horizontal plane) and ejects the O-rings upwards at the ejection station. The transfer mechanism 2 includes at least a vertically arranged first tensioning cylinder 209, which holds the O-rings ejected upwards by the top feeding mechanism 1 against its outer wall. The first unloading mechanism 25 releases the O-rings held by the transfer mechanism 2 downwards.

[0035] Please refer to the following: Figure 2In the first embodiment, the top feeding mechanism 1 includes a first support 100 and a top plate 102 fixed to the top of the first support 100. Two guide members 104 are fixed on the top plate 102, respectively positioned opposite each other on the left and right sides of the vibrating feeding plate 3 in the discharge direction. A receiving groove 103 is formed between the two guide members 104 to receive O-rings conveyed by the vibrating feeding plate 3. The top feeding mechanism 1 also includes a pushing mechanism, which pushes the O-rings on the receiving groove 103 one by one along a pushing groove 106 to a vertical through-hole 113 opened on a fixed block 105. The pushing mechanism specifically includes a pushing cylinder 108, a connecting member 110, and a pushing member 107. A first guide rail 109 is fixed on the top plate 102, and the pushing member 107 is fixed to a connecting member 110, which is slidably disposed on the first guide rail 109. A fixing block 105 is fixed to the first support 100, and a pusher groove 106 is formed thereon to guide one end of the pusher 107. The pusher groove 106 intersects the end of the top plate 102 away from the vibrating feed plate 3. The cylinder body of the pusher cylinder 108 is fixed to the top plate 102, and the piston rod of the pusher cylinder 108 is fixed to the connector 110. The cylinder body of a top-feeding cylinder 111 is fixed to the first support 100, and its piston rod is fixedly connected upward to a support cone 101 and a top-feeding cylinder 112. The support cone 101 is fixed at the center of the top-feeding cylinder 112 and passes upward through the top-feeding cylinder 112 to support the first O-ring seal 01 on the conical surface of the support cone 101. When the top-loading cylinder 111 moves upward to drive the support cone 101 upward into the first tensioning cylinder 209, the top-loading cylinder 112 presses the first O-ring 01 against the outer wall of the first tensioning cylinder 209, and the outer wall of the first tensioning cylinder 209 tightens and holds the first O-ring 01. In order to make the first O-ring 01 more smoothly pressed upward by the top-loading cylinder 112 against the outer wall of the first tensioning cylinder 209, the lower end of the inner cavity of the first tensioning cylinder 209 forms a first flared opening 05 to accommodate the top of the support cone 101, and the lower inner diameter of the flared opening should be as close as possible to the lower outer diameter of the support cone 101.

[0036] The material transfer mechanism 2 includes a horizontal plate 208 fixed to the upper end of the first tensioning cylinder 209. Driven by a first drive mechanism (not labeled), the horizontal plate 208 moves vertically downwards towards the ejection station to receive the ejected O-rings. The first drive mechanism can be any known type of drive mechanism, including lifting drive mechanisms, two-axis drive mechanisms, or multi-axis drive mechanisms.

[0037] Please refer to the following: Figure 3The first ejection mechanism 25 of the first embodiment includes a finger cylinder 253 and a second drive mechanism for driving the finger cylinder 253 to rise and fall. The finger cylinder 253 has fingers 254 that can open and close inwards. A first paddle 255 is fixed on the finger 254 to push the O-ring seals downwards away from the first tensioning cylinder 209. In some other embodiments, preferably, a second paddle 256 is also fixed on the finger 254. The second paddle 256 and the first paddle 255 are vertically aligned and can only accommodate one O-ring seal between them. This allows multiple first O-ring seals 01 to be tensioned at once and then ejected one by one, thereby improving production efficiency. The second drive mechanism may include a second lifting cylinder 251, a third support 250, and a third seat plate 252. The cylinder body of the second lifting cylinder 251 is fixed on the third support 250, and the piston rod of the second lifting cylinder 251 is fixed upward on the third seat plate 252. The cylinder body of the finger cylinder 253 is fixed on the third seat plate 252.

[0038] Please refer to the following: Figure 4 The second embodiment provides a second ejection mechanism 24 that can replace the first ejection mechanism 25. The second ejection mechanism 24 may include an ejection cylinder 240 that is movably sleeved outside the first tensioning cylinder 209. For example, a horizontal plate 208 is fixedly connected to the cylinder body of a third lifting cylinder 242. The piston rod of the third lifting cylinder 242 extends downward into the interior of the first tensioning cylinder 209 and is fixedly connected to a connecting core 241. The connecting core 241 and the ejection cylinder 240 are fixedly connected by fasteners such as locking screws. The first tensioning cylinder 209 is provided with a clearance groove for the locking screw.

[0039] Please refer to the following: Figure 5Based on the second embodiment, the automatic O-ring feeding device of the third embodiment further includes a second tensioning cylinder 26. The second O-ring 02 has a smaller inner diameter than the first O-ring 01. The second tensioning cylinder 26 is fixed to the lower end of the connecting core 241 and located inside the first tensioning cylinder 209. When the second tensioning cylinder 26 descends with the ejector cylinder 240, it can receive and hold the second O-ring 02 from the ejector station of an additional ejector mechanism 1. The second O-ring 02 can be accommodated in the space between the second tensioning cylinder 26 and the first flared opening 05 of the first O-ring 01. When the second tensioning cylinder 26 rises with the ejector cylinder 240, the second O-ring 02 is released under the pressure of the first flared opening 05 of the first O-ring 01 (the radial gap between the first tensioning cylinder 209 and the second tensioning cylinder 26 is preferably smaller than the wire diameter of the second O-ring 02 to ensure that the second O-ring 02 can be removed by the inner wall of the first flared opening 05). The additional ejector mechanism 1 can be fed by an additional vibrating feeder 3. The lower end of the inner cavity of the second tensioning cylinder 26 forms a second flared opening 06 that can accommodate the top of the support cone 101.

[0040] Thus, for applications requiring double sealing using two O-rings with different inner diameters (e.g.) Figure 6 As shown, in the case where the first component 03 and the second component 04 are sealed with two O-rings for inner and outer double-layer sealing, the first O-ring 01 and the second O-ring 02 can be received first, and then the second O-ring 02 can be released first and the first O-ring 01 can be released only by driving the connecting core 241 down and then up once, so as to improve efficiency.

[0041] Please refer to the following: Figure 7 In other embodiments, two first tensioning cylinders 209 can be provided on the horizontal plate 208, and two second unloading mechanisms 24 can be provided correspondingly. A top-loading mechanism 1 and a vibrating feeding plate 3 can also be added, such that when the first tensioning cylinder 209 is in the ejection position of one top-loading mechanism 1, the second tensioning cylinder 209 is in the release position; when the first tensioning cylinder 209 is in the release position, the second tensioning cylinder 209 is in the ejection position of the other top-loading mechanism 1. For example, the ejection positions of the two top-loading mechanisms 1 can be respectively set on opposite horizontal sides of the release position, and the distance between them is equal to the distance between the two horizontal plates 208. The two tensioning cylinders 209 and the two ejection positions are located on the same horizontal straight line, and one of the tensioning cylinders 209 can be moved back and forth between the corresponding ejection position and the release position by a first driving mechanism. In this case, the first driving mechanism can be... Figure 6The XY two-axis drive mechanism shown includes a linear drive mechanism and a first lifting cylinder 206. The linear drive mechanism includes a horizontal cylinder 204, a first base plate 203, a second guide rail 205, a mounting plate 202, and a second support 201. The mounting plate 202 is fixed to the top of the second support 201, the second guide rail 205 is mounted on the mounting plate 202, the first base plate 203 is slidably mounted on the second guide rail 205, the cylinder body of the horizontal cylinder 204 is fixed to the mounting plate 202, and the piston rod of the horizontal cylinder 204 is fixed to the first base plate 203. The cylinder body of the first lifting cylinder 206 is fixed to the first base plate 203, and the piston rod of the first lifting cylinder 206 is fixed downwards to the horizontal plate 208.
