DETAILED DESCRIPTION

[0062] The automatic installation machine of the lip type sealing ring and the control method thereof will be described in detail below in combination with the drawings and specific embodiments.

[0063] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Similarly, the terms "first," "second," etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship, and therefore should not be construed as a limitation of this invention.

[0064] Example 1

[0065] like Figure 1 As shown, an automatic lip seal installation machine includes:

[0066] Base 1, used to support the entire installation machine;

[0067] Product placement platform 2 is movably mounted on base 1 to accommodate the product to be installed;

[0068] The oiling unit 3 is placed above the product placement platform 2 and is used to automatically apply oil to the sealing ring 5 to be installed on the product to be installed.

[0069] The sealing ring installation unit 4 is fixedly installed on the base 1. After the sealing ring 5 is coated with oil, it is moved to the sealing ring installation unit 4. The sealing ring installation unit 4 presses down on the sealing ring to complete the installation of the sealing ring.

[0070] Specifically, in the aforementioned automatic lip seal installation machine, the product to be installed is first placed on the product placement platform 2, and then the seal 5 to be installed is placed in the seal 5 installation area of ​​the product. Next, the oiling unit 3 is activated, pressing down to apply oil to the seal 5. Subsequently, the product placement platform 2 moves to the seal 5 installation unit 4, which presses down, causing the seal 5 to snap into the seal 5 installation area of ​​the product, thus achieving fully automatic installation of the seal 5. The entire process requires no additional manual operation, automatically completing the oiling and installation of the seal 5, significantly accelerating installation efficiency and reducing labor costs. Furthermore, the oiling and installation process eliminates the need for manual operation by workers, preventing them from coming into contact with the lubricating oil, making the entire installation process cleaner.

[0071] Furthermore, such as Figure 2 As shown, the oiling unit 3 includes:

[0072] The first cylinder 31 is fixedly mounted on the base 1;

[0073] The glue dispenser host 32 can be installed on the base 1 or beside the base 1.

[0074] The rubber tube 33 is used to contain lubricating oil, is fixedly installed on the telescopic shaft of the first cylinder 31, and is connected with the glue dispenser host 32. The glue dispenser host 32 drives the lubricating oil in the rubber tube 33 to press down to extrude after being started;

[0075] The oil coating nozzle 34 is fixedly installed at the bottom of the rubber tube 33 and is located directly above the sealing ring installation area. The extruded lubricating oil in the rubber tube 33 is coated on the sealing ring through the oil coating nozzle 34.

[0076] Specifically, when the sealing ring needs to be coated with oil, the product to be installed is placed on the product placement table 2, and the sealing ring to be installed is placed on the sealing ring installation area of the product to be installed. Then, the first cylinder 31 is started to drive the rubber tube 33 and the oil coating nozzle 34 to move downward together until the oil coating nozzle 34 moves to the sealing ring and is inserted into the sealing ring. At this time, the glue dispenser host 32 is started, the lubricating oil in the rubber tube 33 is extruded, enters the oil coating nozzle 34, and is injected into the sealing ring, so as to realize the oil coating process of the sealing ring. It is worth pointing out that the process of moving the oil coating nozzle 34 to the sealing ring and extruding the lubricating oil by the glue dispenser host 32 does not need manual operation, that is, the lubricating oil coating process is fully automatic. The whole process is efficient and saves labor.

[0077] Further, as shown in Figure 3 and 4 , the product placement table 2 comprises:

[0078] The cylinder support plate 21 is arranged on the base 1, and the stroke groove 26 is formed in the cylinder support plate 21.

[0079] The rotating push head 22 is inserted into the stroke groove 26 and moves in the stroke groove 26.

[0080] The rotating column 23 is fixedly installed on the cylinder support plate 21.

[0081] The product positioning plate 24 is movably arranged on the cylinder support plate 21, and the rotating column 23 is movably inserted into the product positioning plate 24. The upper end of the rotating push head 22 abuts below the product positioning plate 24, the positioning shape of which matches the shape of the product to be installed, and the extension line of the rotating column 23 passes through the center of the sealing ring installation area.

[0082] The second cylinder 25 is installed on the base 1, and the lower end of the rotating push head 22 is fixedly installed on the telescopic shaft of the second cylinder 25.

[0083] Specifically, in the product placing table 2, when the sealing ring is oiled, the second cylinder 25 is started, the telescopic shaft moves away from the sealing ring mounting unit 4, pushes the rotating push head to move in the stroke groove 26, and further pushes the product positioning plate 24 to rotate around the rotating column 23. Correspondingly, the to-be-mounted product and the to-be-mounted sealing ring 5 in the product positioning plate 24 are also rotated around the rotating column 23. Since the extension line of the rotating column 23 passes through the center of the sealing ring mounting area, the entire to-be-mounted sealing ring 5 rotates around the center of the sealing ring, thereby achieving all-around oiling of the to-be-mounted sealing ring 5 and ensuring uniform and comprehensive oiling. That is, the oiling is changed from point to surface oiling of the entire inner / outer ring, so that the oiling achieves a point-to-surface conversion effect. In addition, when it is needed to move the to-be-mounted product to below the sealing ring mounting unit 4, only the second cylinder 25 needs to be started, and the telescopic shaft is retracted. When the rotating push head 22 reacts and moves to abut against the side edge of the stroke groove 26 close to the sealing ring mounting unit 4, the entire cylinder supporting plate 21 is pushed by the rotating push head 22 and moves along a straight line direction toward the sealing ring mounting unit 4 along with the second cylinder 25. That is, the forward pushing of the second cylinder 25 can realize the rotation of the product positioning plate 24, and the rearward retraction can realize the straight line movement of the entire cylinder supporting plate 21, that is, it can ensure all-around oiling of the to-be-mounted sealing ring 5 and can also realize the movement of the to-be-mounted product and the to-be-mounted sealing ring to below the sealing ring mounting unit 4. The device uses one cylinder to realize multiple functions, simplifies the structure and saves the cost of the instrument.

[0084] Further, due to the limitation of the stroke groove 26, the pushing distance of the second cylinder 25 is limited, and the rotation angle of the product positioning plate 24 is limited, and the rotation angle is at most 30 degrees. Since the oil nozzle 343 is uniformly provided with multiple transverse oil guide cavities 346, the product positioning plate 24 only needs to rotate by a small angle, and the entire ring of the sealing ring can be uniformly oiled. That is, under the condition of ensuring uniform oiling, the entire rotation process is shorter and more efficient. In addition, the small rotation angle can reduce the rotation space of the product and the space required by the entire device, so that the entire device structure is more compact and small.

[0085] Further, the bottom of the cylinder supporting plate 21 is further provided with a cylinder seat 27, and the telescopic shaft of the second cylinder 25 is fixedly installed on the rotating push head 22 after penetrating through the cylinder seat 27.

[0086] Further, as shown in Figures 5-7 the oiling nozzle 34 includes:

[0087] a nozzle fixing plate 341 fixedly connected with the bottom of the rubber pipe 33 and communicated with the bottom of the rubber pipe 33;

[0088] The oil storage tube 342 is internally provided with an oil storage cavity 344, is located at the bottom of the nozzle fixing plate 341 and is communicated with the rubber tube 33, and the bottom of the oil storage tube 342 is provided with a plurality of longitudinal oil guide cavities 345, which are all communicated with the oil outlet cavity;

[0089] The oil nozzle 343 is fixedly arranged at the bottom of the oil storage tube 342, and a plurality of transverse oil guide cavities 346 are distributed on the oil nozzle 343 and are communicated with the longitudinal oil guide cavities 345 one by one.

[0090] Specifically, when the glue dispensing machine host 32 drives the lubricating oil in the rubber tube 33 to be extruded, the lubricating oil enters the oil storage cavity 344 of the oil storage tube 342, and then enters the corresponding transverse oil guide cavity 346 through the longitudinal oil guide cavity 345 one by one. It is worth pointing out that, since the oil nozzle 343 is inserted into the inner side of the to-be-installed sealing ring after moving downward, the arrangement of the plurality of transverse oil guide cavities 346 helps the lubricating oil to be evenly applied to the sealing ring in multiple directions, and in cooperation with the action of the second cylinder 25, the uniform oil application process to the sealing ring can be completed.

[0091] Further, the lower part of the oil nozzle 343 is in a ring structure, that is, it is a groove inside, and the transverse oil guide cavities 346 penetrate through the inner and outer sides of the ring-shaped oil nozzle 343. As shown in Figure 8 for the sealing ring with the ring-shaped track inside, the lower part of the above-mentioned nozzle can be clamped on the ring-shaped track of the sealing ring, and the transversely arranged transverse oil guide cavities 346 can apply oil to both sides of the ring-shaped track of the sealing ring, thereby ensuring the comprehensiveness of oil application.

[0092] Further, the above-mentioned oil application unit 3 further comprises a cylinder fixing plate 35 and a rubber tube support plate 36, the cylinder fixing plate 35 is fixedly installed on the base 1, the first cylinder 31 is fixedly installed on the cylinder fixing plate 35, and the rubber tube support plate 36 is fixedly connected with the rubber tube 33. The output shaft of the first cylinder 31 abuts against the rubber tube support plate 36, thereby driving the rubber tube support plate 36 and the rubber tube 33 to move upward or downward.

[0093] Further, the above-mentioned oil application unit 3 further comprises a connecting plate 37 fixedly installed on the rubber tube support plate 36, the connecting plate 37 is arranged between the rubber tube 33 and the oil application nozzle 34, and is used to fix the oil application nozzle 34 to prevent the oil application nozzle 34 from being loose.

[0094] Further, as shown in Figure 9 the nozzle fixing plate 341 of the oil application nozzle 34 is fixedly connected with the connecting plate 37 through bolts.

[0095] Further, the sealing ring installation unit 4 comprises:

[0096] The cylinder fixing seat 41 is fixedly installed on the base 1;

[0097] The third cylinder 42 is installed on the top of the cylinder fixing base 41 and extends vertically downward;

[0098] The pressing head device 43 is installed on the bottom of the third cylinder 42 and is used to install the oiled sealing ring on the product.

[0099] Specifically, when the sealing ring is oiled, the second cylinder 25 drives the product positioning plate 24 and the sealing ring to be installed 5 on the sealing ring installation area to move to the pressing head device 43, and the third motor is started to drive the pressing head device 43 to press down on the sealing ring, so as to fix the sealing ring on the sealing ring installation area, and the automatic installation of the sealing ring is completed.

[0100] Further, as shown in the drawings, the pressing head device 43 comprises: Figures 10-12

[0101] The guide block 431 is horizontally arranged and fixedly installed on both sides of the cylinder fixing base 41, and the guide hole is arranged on the guide block 431;

[0102] The linear bushing 432 moves up and down along the guide hole;

[0103] The sealing ring installation pressing head 433 is arranged in the linear bushing 432, and the output shaft of the third cylinder 42 abuts against the top of the sealing ring installation pressing head 433;

[0104] The magnet 434 is arranged at the bottom of the sealing ring installation pressing head 433.

[0105] Specifically, when the sealing ring needs to be installed, the third cylinder 42 is started to drive the sealing ring installation pressing head 433 to press down, at this time, the linear bushing 432 also moves downward. Since the linear bushing 432 needs to move vertically up and down along the guide hole, the sealing ring installation pressing head 433 is limited, and it is not easy to have angle deflection and the like, so as to ensure that the sealing ring installation pressing head 433 can accurately press down on the corresponding area of the sealing ring to be installed 5. In addition, since the sealing ring has a metal skeleton, the arrangement of the magnet 434 ensures that the sealing ring will not fall off during the pressing process, and the accuracy of the entire pressing process is ensured.

[0106] Further, the bottom of the sealing ring installation pressing head 433 is in a ring structure, which cooperates with the size of the ring-shaped track of the sealing ring, can abut against the ring-shaped track, ensures that the sealing ring is installed without damaging the sealing ring. Due to the special design of the sealing ring shape, the phenomenon of the sealing ring being installed in reverse can be effectively prevented.

[0107] Further, as shown in the drawings, Figure 13 ​As shown, the guiding block 431 is further provided with an anti-lifting rod 45, the rod body is provided with threads, and the anti-lifting rod 45 is fixedly installed on the guiding block 431 through a nut. The height can be adjusted according to actual needs, so that the bottom can abut against the product to be installed. Because there is suction force between the sealing ring and the pressure head device 43, the product will be lifted during the resetting process after installation. The anti-lifting rod abutting against the product can well solve this problem.

[0108] Further, the above-mentioned installation machine further comprises a main machine, the first cylinder 31, the second cylinder 25 and the third cylinder 42 are electrically connected with the main machine, and the main machine controls the error-proofing of the installation machine in the movement process by using the inductors on the cylinders and the motor and cooperating with the main machine control program. When the specified position is not reached, the main machine controls the device to stop forcibly, and the next step cannot be performed, so that the occurrence and outflow of defective products are completely eliminated, and the quality defects caused by changes in human factors are reduced.

[0109] In the above-mentioned automatic installation machine for lip-type sealing rings, first, the product to be installed is placed on the product placing table 2, and the sealing ring to be installed is placed on the sealing ring installation area of the product to be installed. Then, the oiling unit 3 is started, and the oiling unit 3 is pressed down to realize oiling of the sealing ring. Subsequently, the product placing table 2 moves to the sealing ring installation unit 4, the sealing ring installation unit 4 is pressed down, and the sealing ring is immediately clamped into the sealing ring installation area of the product to be installed, so as to realize automatic installation of the sealing ring of the product. In the whole process, no additional manual operation is required, and the labor cost is reduced due to the arrangement of multiple horizontal oil guide cavities 346. In addition, the process from oiling to installation does not require manual operation by workers, and the workers will not touch the lubricating oil, so that the whole installation process is cleaner. The arrangement of multiple horizontal oil guide cavities 346 helps to uniformly apply the lubricating oil to multiple directions of the sealing ring, and the forward pushing of the second cylinder 25 can complete the uniform oiling process of the sealing ring. In addition, smaller rotation angle can reduce the rotation space of the product, reduce the space required by the whole device, and make the whole device more compact and small. In addition, the whole installation machine is designed according to ergonomics (i.e., the left hand places the product and the right hand places the sealing ring), and the movement is planned to achieve reasonable distribution of man-machine operation time, reduce operation waste, and improve efficiency.

[0110] Embodiment Two

[0111] According to the automatic installation machine for lip-type sealing rings proposed in the above-mentioned embodiment, the present embodiment proposes a control method of the automatic installation machine for lip-type sealing rings.

[0112] As shown in Figure 14 A control method of an automatic installation machine for lip-type sealing rings, comprising the steps of:

[0113] S1, the artificial in turn on the product positioning plate 24 placed to be installed products and in the sealing ring installation area placed to be installed sealing ring 5, start the main machine;

[0114] S2, the first cylinder 31 starts, drives the rubber tube 33 to move down to the place where the sealing ring 5 to be installed, the glue gun starts, the lubricating oil in the rubber tube 33 is coated in the sealing ring 5 to be installed through the oil coating nozzle 34;

[0115] S3, the second cylinder 25 starts, drives the rotary push head 22 to move in the stroke groove 26, and then drives the product positioning plate 24 to rotate around the rotary column 23 by a preset angle and then returns to the original position;

[0116] S4, the first cylinder 31 starts to drive the oil coating nozzle 34 to move away from the sealing ring 5 to be installed, and the second cylinder 25 drags the rotary push head 22 away from the stroke groove 26, the rotary push head 22 abuts against the side of the stroke groove 26 to drag the cylinder support plate 21 to move together, and drives the product positioning plate 24 to move to the lower side of the sealing ring installation unit 4;

[0117] S5, the third cylinder 42 in the sealing ring installation unit 4 starts, drives the pressure head device 43 to press down, the sealing ring installation pressure head 433 abuts against the sealing ring 5 to be installed, and then continues to press down until the sealing ring 5 to be installed is fixed in the sealing ring installation area.

[0118] Specifically, in the control method of the above-mentioned automatic lip seal installation machine, after the operator places the product to be installed on the product positioning plate 24, the seal 5 to be installed is placed in the seal 5 placement area of ​​the product to be installed. Then, the oiling unit 3 starts working. The first cylinder 31 drives the oiling nozzle 34 to move down to the seal area to be installed, and the dispensing machine starts to apply the lubricating oil in the glue tube 33 through the oiling nozzle to the seal area to be installed. Afterwards, the second cylinder 25 in the product placement table 2 starts, driving the rotating push head 22 to move in the stroke groove 26, which in turn drives the product positioning plate 24 to rotate around the rotating column 23, which in turn drives the seal 5 to be installed to rotate, thereby achieving all-round oiling of the seal. After oiling, the first cylinder 31 moves the oiling nozzle 34 away from the sealing ring 5 to be installed. The second cylinder 25 drags the rotating push head 22 away from the stroke groove 26. After the rotating push head 22 abuts against the side of the stroke groove 26, it drags the cylinder support plate 21 to move together, thus moving the product to be installed and the sealing ring 5 to be installed to the sealing ring installation unit 4. The third cylinder 42 is activated, driving the pressure head device 43 to press down. The sealing ring installation pressure head 433 abuts against the sealing ring 5 to be installed, and continues to press down until the sealing ring is completely installed in the sealing ring installation area, thus realizing the oiling and installation process of the sealing ring. The entire process, except for the placement of the product and the sealing ring, does not require additional manual operation. It can realize the oiling and installation of the sealing ring automatically, which greatly speeds up the installation efficiency of the sealing ring and reduces labor costs. In addition, the process from oiling to installation does not require manual operation by workers, and workers will not come into contact with lubricating oil, so the entire installation process is cleaner.

[0119] Furthermore, in step S3 above, the preset angle is 30 degrees.

[0120] Furthermore, in step S5 above, when the sealing ring installation head 433 abuts against the sealing ring 5 to be installed, the magnet 434 at the bottom of the sealing ring installation head 433 generates an attractive force with the metal wire in the sealing ring 5 to be installed, ensuring that the sealing ring will not fall off the sealing ring installation head 433 during the pressing and installation process, thus ensuring the accuracy of the entire installation.

[0121] Furthermore, such as Figure 15 As shown, the step S5 above is followed by the following step:

[0122] S6. The third cylinder 42 starts, driving the sealing ring installation head 433 to move upward. The anti-slip rod 45 abuts against the product, and the sealing ring installation head 433 disengages from the sealing ring, ending the installation process.

[0123] During this process, due to the suction between the sealing ring and the pressure head device 43, the product will be lifted during the reset process after installation. The release rod that abuts against the product can solve this problem well.

[0124] Further, the inductors on each cylinder and motor are used to control the error-proofing during the operation process in cooperation with the main control program. When the specified position is not reached, the main control device will be forced to stop and the next step will not be performed, thus completely eliminating the occurrence and outflow of defective products and reducing the quality defects caused by human factors.

[0125] In the control method of the automatic lip seal ring installation machine, the entire process can be fully automated to realize the oiling and installation of the seal ring without additional manual operation, greatly improving the installation efficiency of the seal ring and reducing the labor cost. In addition, the process from oiling to installation does not require manual operation by workers, and the workers will not touch the lubricating oil, so the entire installation process is cleaner. In addition, each action device is precisely controlled by the main machine, completely eliminating the occurrence and outflow of defective products and reducing the quality defects caused by human factors.

[0126] For those skilled in the art, after reading the above description, various changes and modifications will undoubtedly be apparent. Therefore, the appended claims should be considered as covering all changes and modifications within the true intent and scope of the present application. Any and all equivalent ranges and contents within the scope of the claims should be considered as still within the intent and scope of the present application.
