[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0038] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] like Figure 1 , Figure 2 As shown, the present invention provides an automatic plastic gasket feeding device, including a workbench module 1, a feeding module 3, a hopper module 2, and a pushing module 4. The feeding module 3, the hopper module 2, and the pushing module 4 are all installed on the workbench module 1. The hopper module 2 is used to store the plastic gaskets to be fed, the feeding module 3 is used to pick up and transfer the plastic gaskets on the hopper module 2, and the pushing module 4 is used to push the plastic gaskets in the hopper module 2 to ensure that the position where the feeding module 3 picks up the material on the hopper module 2 always has a plastic gasket, thereby ensuring the picking and transfer of the material by the feeding module 3.

[0040] The hopper module 2 has multiple gasket storage stations, each capable of storing plastic gaskets to be picked up and transferred. These gasket storage stations can be adjusted by rotating the hopper module 2, ensuring that the gasket storage station corresponding to the feeding module 3 is not a fixed station. This allows the feeding module 3 to pick up and transfer plastic gaskets from one of the gasket storage stations in the hopper module 2 while the other gasket storage stations replenish the gaskets to be picked up and transferred. This avoids the need to stop the machine to replenish gaskets at each storage station after they have been picked up and transferred by the feeding module 3, thus improving the feeding efficiency of plastic gaskets.

[0041] In this utility model, in order to meet the requirement of replenishing plastic gaskets to the gasket storage station without stopping the machine, there are at least two gasket storage stations. Of course, the number of gasket storage stations can also be three, four, or even more. The number of gasket storage stations can be determined by comprehensively considering factors such as the time required to replenish plastic gaskets to the gasket storage station and the area occupied by the hopper module 2 on the workbench module 1.

[0042] In this utility model, it should be noted that the adjustable position of the multiple gasket storage stations means that the position of the multiple gasket storage stations relative to the feeding module 3 can be adjusted. That is, the gasket storage station can be located at the material picking position of the feeding module 3, or the gasket storage station can be offset from the material picking position of the feeding module 3, so that after all the plastic gaskets on one gasket storage station are picked up and transferred by the feeding module 3, the other gasket storage station can move to a position for the feeding module 3 to pick up, thereby satisfying continuous feeding.

[0043] Of course, in this utility model, the positions of the multiple gasket storage stations can be adjusted not only by rotation but also by translation. For example, after all the plastic gaskets on the first gasket storage station are picked up and transferred by the feeding module 3, the first gasket storage station is translated and moved away from the picking position of the feeding module 3. At this time, the gasket storage station can replenish the plastic gaskets. The next gasket storage station is translated to the picking position of the feeding module 3. After all the plastic gaskets on the gasket storage station are picked up and transferred by the feeding module 3, the two gasket storage stations are reset, so that the gasket storage station that has completed the replenishment of plastic gaskets corresponds to the picking position of the feeding module 3, and plastic gaskets are replenished to the gasket storage station that has finished picking up plastic gaskets. This can be repeated to meet the continuous feeding requirements.

[0044] As the feeding module 3 picks up and transfers plastic washers from the washer storage station, the number of plastic washers in the storage station decreases. Therefore, in order to ensure that the picking position of the plastic washer in the washer storage station for the feeding module 3 to pick up plastic washers is always available, the pushing module 4 can push the plastic washers in the washer storage station. The pushing module 4 pushes the plastic washer in the washer storage station a distance equal to the thickness of one plastic washer each time, so as to ensure that the picking position of the plastic washer in the washer storage station for the feeding module 3 to pick up plastic washers can always meet the picking needs of the feeding module 3.

[0045] In this utility model, such as Figure 3As shown, the hopper module 2 includes a support frame 201, which is supported on the workbench module 1 by multiple support legs. A rotating element is installed on the support frame 201, and a turntable 203 is installed at the output end of the rotating element. The turntable 203 is arranged horizontally, and multiple washer storage stations are evenly spaced circumferentially around the rotation center of the turntable 203. That is, during the process of the rotating element driving the turntable 203 to rotate, the distance between the multiple washer storage stations and the rotation center of the turntable 203 remains constant. When one of the washer storage stations in the hopper module 2 corresponds to the picking station of the feeding module 3, the rotation of the rotating element can rotate the next washer storage station to the picking station corresponding to the feeding module 3, thereby satisfying the feeding module 3 to pick up and transfer the plastic washers on the multiple washer storage stations.

[0046] In this invention, the rotating element is a rotary cylinder 202; of course, if noise and other requirements are not considered, the rotating element can also be replaced by a drive motor or the like.

[0047] To ensure the stability of the plastic washer in the washer storage station, the washer storage station also includes a base 208 mounted on the turntable 203. The base 208 supports the plastic washer, and a limiting guide shaft 204 that mates with the inner ring of the plastic washer is also installed on the base 208. When the plastic washer needs to be placed in the washer storage station, the plastic washer is fitted inside the limiting guide shaft 204, thereby preventing the plastic washer from having a horizontal position in the washer storage station, thus achieving horizontal limiting of the plastic washer in the washer storage station.

[0048] Because the plastic washer in this invention has a locking tab on its outer edge, in order to ensure that the locking tab on the plastic washer in the storage station remains fixed when the feeding module 3 picks up the plastic washer, it is necessary to prevent the plastic washer from rotating horizontally in the storage station after it is placed in the storage station. Therefore, two limiting rods 205 are also installed on the base 208. The two limiting rods 205 are symmetrically arranged about the central axis of the limiting guide shaft 204, and the limiting rods 205 are locked to the locking tab on the plastic washer. The design incorporates a snap-fit ​​mechanism, allowing workers to directly insert plastic washers into the washer storage station by aligning the snap-fit ​​on the plastic washer with the limiting rod 205. The engagement of the limiting rod 205 with the snap-fit ​​on the plastic washer effectively prevents the plastic washer from rotating after being fitted onto the limiting guide shaft 204. This ensures that the position of the plastic washer remains fixed when the feeding module 3 picks it up from the storage station, allowing for direct installation of the plastic washer after it has been transferred by the feeding module 3, without the need to readjust its orientation.

[0049] In this invention, to facilitate the pushing of plastic washers in the washer storage station by the pushing module 4, a support plate 206 for holding the plastic washers is also installed on the base 208, and the support plate 206 has a through hole that fits with the limiting guide shaft 204. Through the through hole on the support plate 206 and the clearance fit with the limiting guide shaft 204, after the plastic washer is fitted onto the limiting guide shaft 204, the support plate 206 moves up and down on the limiting guide shaft 204, pushing the plastic washer on the limiting guide shaft 204. This avoids damage to the plastic washer caused by the pushing module 4 during the pushing process, and also prevents the pushing module 4 from failing to effectively clamp the plastic washer during the pushing process.

[0050] In this invention, to ensure that the feeding module 3 can promptly detect whether there are plastic washers at the washer storage station before picking up materials, a mounting frame supported by a support shaft is also installed on the support frame 201. The mounting frame is U-shaped and located outside the picking position of the feeding module 3 at the washer storage station. Both ends of the mounting frame are equipped with photoelectric switches 207. The photoelectric switches 207 detect whether there are plastic washers at the picking position of the feeding module 3 at the washer storage station. This ensures that the feeding module 3 can pick up and transfer plastic washers in the future. On the other hand, it ensures that when the photoelectric switches 207 detect that there are no plastic washers at the picking position of the feeding module 3 at the washer storage station, the position of the washer storage station can be adjusted in time, thereby transferring the washer storage station containing plastic washers to the picking position of the feeding module 3.

[0051] In this utility model, in order to ensure the picking up and transfer of plastic gaskets by the feeding module 3, such as Figure 4As shown, the feeding module 3 includes a stand 301 fixed on the workbench module 1. The stand 301 is located on one side of the hopper module 2, and a horizontally extending linear guide rail 303 is installed on the stand 301. A slider 304 that can reciprocate along its axis is installed on the linear guide rail 303. A connecting plate 305 is installed on the slider 304. The slider 304 moves on the linear guide rail 303, which drives the connecting plate 305 to move. A vertical telescopic element 306 is also installed on the connecting plate 305. The driving direction of the vertical telescopic element 306 is consistent with the vertical direction, and a vacuum suction cup 307 is installed on the output shaft of the vertical telescopic element 306. With the cooperation of linear guide rail 303 and slider 304, when slider 304 slides on linear guide rail 303, slider 304 drives connecting plate 305, vertical telescopic element 306 and cylinder to move synchronously, so that vacuum suction cup 307 enters above the gasket storage station for material feeding and picking. At this time, with the extension and retraction of vertical telescopic element 306, vertical telescopic element 306 drives vacuum suction cup 307 to move up and down, so that vacuum suction cup 307 moves closer to or away from the picking position on gasket storage station, thereby facilitating vacuum suction cup 307 to pick up plastic gaskets in gasket storage station.

[0052] To ensure the sliding of the slider 304, a horizontal drive element 302 is also installed on the stand 301. The horizontal drive element 302 is a linear motor. The direction of movement of the horizontal drive element 302 is consistent with the axial direction of the linear guide rail 303. The output end of the horizontal drive element 302 is connected to the connecting plate 305, so that the horizontal drive element 302 drives the connecting plate 305 to move synchronously while moving. Through the cooperation of the slider 304 and the linear guide rail 303, the movement of the connecting plate 305 is made more stable, so that the vacuum suction cup 307 and the vertical telescopic element 306 move more smoothly with the connecting plate 305.

[0053] In this utility model, the number of linear guide rails 303 can be one or more. When there are multiple linear guide rails 303, sliders 304 are installed on each of the multiple linear guide rails 303. At this time, connecting plates 305 are installed on multiple sliders 304. Meanwhile, without considering noise and other requirements, the horizontal drive element 302 can also adopt a screw and nut structure or a rodless cylinder structure.

[0054] In this invention, to ensure a more stable gripping of the plastic pad by the vacuum suction cup 307, there can be two, three, or four vacuum suction cups 307. When there are multiple vacuum suction cups 307, since the plastic pad is annular, the multiple vacuum suction cups 307 are arranged in a ring. In this invention, the vertical telescopic element 306 can be directly a cylinder. Of course, if noise and other requirements are not considered, the vertical telescopic element 306 can also be replaced by a hydraulic cylinder, an electronic telescopic rod, etc.

[0055] In this utility model, to ensure that the plastic gaskets are pushed from the gasket storage station to the position for pickup by the vacuum suction cup 307 during the feeding process, the pushing module 4 can promptly push the plastic gaskets to the position for pickup by the vacuum suction cup 307. Figure 5 As shown, the feeding module 4 includes a vertical drive element 401 installed on the workbench module 1. The driving direction of the vertical telescopic element 306 is consistent with the stacking direction of the plastic gaskets in the gasket storage station. The vertical drive element 401 is located outside the gasket storage station where the feeding module 3 picks up the plastic gaskets. A horizontal telescopic element 402 is also installed at the output end of the vertical telescopic element 306. The horizontal telescopic element 402 extends and retracts in the horizontal direction. A lifting claw 403 is also installed at the output end of the horizontal telescopic element 402. By retracting the horizontal telescopic element 402, the lifting claw 403 can be inserted into or removed from under the pad 206. Since the plastic washer is supported by the pad 206 when it is fitted onto the limiting guide shaft 204, when the lifting claw 403 is inserted below the pad 206, the vertical telescopic element 306 drives the horizontal telescopic element 402 and the lifting claw 403 to move upward. The lifting claw 403 will push the pad 206 and the plastic washer fitted onto the limiting guide shaft 204 upward, thereby realizing the pushing of the plastic washer.

[0056] In this invention, to ensure a more balanced pushing force on the pad 206 during the pushing process of the lifting claw 403, the lifting claw 403 is U-shaped. After the lifting claw 403 is inserted under the pad 206, both sides of the pad 206 can receive the pushing force of the lifting claw 403, making the movement of the pad 206 on the limiting guide shaft 204 more stable, avoiding tilting due to uneven force on the pad 206, and ensuring that the pad 206 can move smoothly along the limiting guide shaft 204.

[0057] In this invention, to facilitate the smooth insertion of the lifting claw 403 under the pad 206 when pushing the plastic washer on the pad 206, the lower surface of the pad 206 also has a support structure. This support structure is integral with the pad 206, and its height is greater than that of the lifting claw 403. By supporting the pad 206 with the support structure, after the pad 206 is fitted onto the limiting guide shaft 204, a certain gap is maintained between the lower surface of the pad 206 and the upper surface of the limiting guide shaft 204. This gap allows the lifting claw 403 to be smoothly inserted under the pad 206, thus enabling the lifting claw 403 to smoothly push the pad 206 and the plastic washer on it upwards during the upward movement driven by the vertical telescopic element 306, thereby achieving the pushing of the plastic washer.

[0058] In this invention, the support structure on the lower surface of the pad 206 can be a sleeve, with a clearance fit between the sleeve and the limiting guide shaft 204. In this case, the pad 206 has a flange structure, which makes the up-and-down movement of the pad 206 on the limiting guide shaft 204 smoother. Of course, in this invention, in addition to the sleeve, the support structure on the lower surface of the pad 206 can also be a support column directly located on the lower surface of the pad 206. In this case, there are two support columns, which are symmetrically arranged on the pad 206. However, in order to avoid the support columns obstructing the insertion of the lifting claw 403, the positions of the two support columns need to avoid the insertion of the lifting claw 403.

[0059] In this utility model, the vertical drive element 401 is a linear motor. If noise and other requirements are not considered, the horizontal drive element 302 can also adopt a screw and nut structure or a rodless cylinder structure. The horizontal telescopic element 402 is a cylinder. If noise and other requirements are not considered, the vertical telescopic element 306 can also be replaced by a hydraulic cylinder, an electronic telescopic rod, etc.

[0060] In this utility model, the workbench module 1 includes a frame structure frame 101, which is formed by constructing profiles. Angle brackets are installed inside the right angles at the connection nodes of the frame 101 to ensure the sturdiness of the frame 101 itself. At the same time, multiple foot cups 103 and multiple foot supports 102 are installed at the lower end of the frame 101. The multiple foot cups 103 are evenly installed at the lower end of the frame 101, and each foot cup 103 corresponds to one foot support 102. After the foot supports 102 and foot cups 103 are installed, the foot supports 102, foot cups 103 and the ground form a triangular structure, making the frame 101 more stable on the ground.

[0061] In use, the pad 206 is first placed on the limiting guide shaft 204, and then the plastic pad to be loaded is placed on the limiting guide shaft 204. During the process of loading the plastic pad, the buckle on the plastic pad is aligned with the limiting rod 205. This process is repeated so that the plastic pads to be loaded are loaded at multiple washer storage stations.

[0062] Next, the horizontal telescopic element 402 extends, pushing the lifting claw 403 to insert below the pad 206; the vertical telescopic element 306 extends, pushing the vacuum suction cup 307 to move until it comes into contact with the plastic pad to be loaded, and the vacuum suction cup 307 picks up the plastic pad, causing it to adhere to the vacuum suction cup 307; the vertical telescopic element 306 retracts, causing the vacuum suction cup 307 to move upward, causing the plastic pad adhered to the vacuum suction cup 307 to move synchronously; the horizontal drive element 302 actuates, and the water... The horizontal drive element 302 drives the connecting plate 305, the vertical telescopic element 306, the vacuum suction cup 307, and the plastic gasket being picked up to move synchronously. During this movement, the slider 304 slides on the linear guide rail 303, providing secondary guidance for the movement of the connecting plate 305, so that the plastic gasket being picked up can be transferred. After the plastic gasket reaches the feeding position, the vertical telescopic element 306 descends again, the vacuum of the vacuum suction cup 307 is broken, and the vacuum suction cup 307 releases the plastic gasket, placing it accurately in the set position. Thus, the entire automatic feeding process of the plastic gasket is successfully completed.

[0063] During the transfer process of the plastic gasket being sucked up, the vertical drive element 401 drives the horizontal telescopic element 402 and the lifting claw 403 to move upward. As the lifting claw 403 moves upward, it pushes the pad 206 to move upward synchronously. As the pad 206 moves upward, it pushes the plastic pad 206 sleeved on the limiting guide shaft 204 to move upward, thereby realizing the pushing of plastic gaskets in the gasket storage station.

[0064] During the transfer of the sucked plastic gaskets, the through-beam switch 207 monitors the status of the plastic gaskets at the material retrieval station within the gasket storage station in real time. When the through-beam switch 207 detects that there are no plastic gaskets at the material retrieval station within the gasket storage station, the horizontal telescopic element 402 retracts. Simultaneously, the horizontal telescopic element retracts, causing the lifting claw 403 to move synchronously, thus retracting the lifting claw 403 from the gasket storage station. Then, the rotary cylinder 202 rotates, causing the turntable 203 and the gasket storage station on the turntable 203 to move synchronously. The rotation causes the gasket storage station, after loading, to rotate to a position offset from the vacuum suction cup 307, and the gasket storage station containing the plastic gasket rotates to the position for picking up the plastic gasket from the vacuum suction cup 307. Simultaneously, the rotary cylinder 202 rotates, and the vertical drive element 401 drives the horizontal telescopic element 402 and the lifting claw 403 downwards, causing the lifting claw 403 to move to its lowest position. Finally, the horizontal telescopic element 402 extends, pushing the lifting claw 403 to insert it under the pad 206, and the above steps are repeated.

[0065] In this utility model, the distance that the pushing module 4 pushes the plastic washer in the washer storage station each time can be greater than the thickness of one plastic washer. At this time, the vacuum suction cup 307 has a certain range of motion at the output end of the vertical telescopic element 306. For example, a fixed plate is installed at the output end of the vertical telescopic element 306, the connecting tube of the vacuum suction cup 307 passes through the fixed plate, and limit nuts are installed at both ends of the connecting tube of the vacuum suction cup 307. A compression spring is sleeved on the connecting tube of the vacuum suction cup 307, one end of the compression spring abuts against one of the limit nuts, and the other end of the compression spring abuts against the fixed plate. This design can compensate for certain positional changes by moving the connecting tube of the vacuum suction cup 307 up and down on the fixed plate, while the compression spring can also ensure the stability of the vacuum suction cup 307. At this time, after the vacuum suction cup 307 picks up a certain number of plastic washers in the washer storage station, the vertical drive element 401 drives the horizontal telescopic element 402 and the lifting claw 403 to move upward. That is, the vacuum suction cup 307 can pick up a certain number of plastic washers in the washer storage station and then push the plastic washers in the washer storage station.

[0066] The automatic plastic gasket feeding device provided by this utility model ingeniously integrates four core components: a workbench module 1, a feeding module 3, a hopper module 2, and a pushing module 4. These components work together to achieve a highly efficient and smooth automated process. First, the workbench module 1, as the stable foundation of the device, not only supports the operation of the entire system but also, through the cooperation of the foot cup 103 and the foot bracket 102, ensures the precise positioning and stable operation of the device in different environments.

[0067] The material hopper module 2 features a unique design with a "dual material hopper" structure driven by a swing-table cylinder, which significantly increases storage capacity and greatly increases the loading of plastic gaskets, thereby effectively reducing the frequency of manual feeding and interference with the production process. At the same time, the photoelectric switch 207 configured in the material hopper module 2 can accurately monitor the status of the material hopper, ensuring real-time monitoring of inventory.

[0068] The core structure of workbench module 1 uses standardized profiles to construct the framework, achieving a stable connection through precision corner brackets. The vertically extending profiles within the frame 101 feature carefully designed tapping at both ends. One side is cleverly fitted with feet 103 to ensure the workbench can be finely adjusted to a level position as needed, while the other side is tightly secured to the large base plate using high-strength screws for a secure connection. The flexibility of workbench module 1 lies in its modular design. Except for the large base plate, all components use standard parts, allowing for flexible selection of profile lengths and adjustment of the large base plate size according to the actual space available at the installation site, thus easily changing the overall dimensions of the workbench.

[0069] The upper part of the workbench module 1 integrates a highly efficient and collaborative material storage module 2, a feeding module 3, and a pushing module 4. The material storage module 2 serves as the storage center, responsible for storing plastic gaskets to be processed. The pushing module 4 plays the role of automated transportation. Through the precise extension and retraction of the horizontal telescopic element 402 and the close cooperation of the vertical drive element 401, as well as the precise sensing of the through-beam switch 207, the plastic gaskets in the gasket storage station are accurately pushed to the preset picking position.

[0070] The entire automated process is cyclical, efficient, and continuous. When the plastic washers in a certain washer storage station are used up, the pusher module 4 will automatically return to its initial position, and the lifting claw 403 will return to its original position. At this time, the swing table cylinder starts its rotation function, automatically switching to the next washer storage station filled with plastic washers, seamlessly connecting to the next round of material handling operations, ensuring the continuity and efficiency of the production process.

[0071] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
