Description

Technical Field

[0001] The invention belongs to the technical field of sealing ring installation, and in particular relates to an automatic sealing ring assembly machine. Background Art

[0002] In the process of mechanical manufacturing and assembly, sealing rings are an important component and are widely used in various mechanical equipment to prevent leakage, maintain pressure and prevent impurities from entering. The traditional sealing ring assembly method mainly relies on manual operation to open the sealing ring and insert it into the card slot of the workpiece or the corresponding structure, but this method has the following problems: manual operation requires repeated opening and inserting actions, which is labor-intensive and inefficient, and the accuracy and consistency of manual operation are difficult to guarantee.

[0003] In order to solve the above problems, various automated sealing ring assembly equipment have emerged in recent years. The Chinese utility model patent with application number 2023222184350 discloses an automatic sealing ring assembly device, which mainly includes multiple hook ring parts, a radial drive mechanism and multiple extendable push rods; the device expands the sealing ring by synchronously expanding multiple hook columns, which reduces the difficulty of installing the sealing ring. At the same time, the push rod drive can realize the sealing ring from the workpiece, which is convenient for operation.

[0004] Most of the existing sealing ring installation methods use more expansion devices to expand the inner diameter of the sealing ring, and then place the workpiece into the sealing ring to complete the subsequent installation of the sealing ring. However, in this method, multiple expansion devices need to operate precisely and synchronously to ensure uniform expansion of the sealing ring; if one of the expansion devices fails or has a working error, it will cause uneven expansion of the sealing ring, thereby affecting the installation quality and efficiency. Summary of the invention

[0005] The present invention proposes an automatic sealing ring assembly machine, which realizes full automation of the sealing ring assembly process through the design of a sealing ring guide rod and a push-in and push-out mechanism coordinated therewith, which not only simplifies the equipment structure and reduces the failure rate, but also effectively avoids instantaneous tension damage to the sealing ring caused by traditional methods, ensures the accuracy and safety of the sealing ring assembly, and improves production efficiency and product quality.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

[0007] An automatic sealing ring assembly machine includes a feeding mechanism and an ejection mechanism and an ejection mechanism arranged on both sides of the feeding mechanism, the feeding mechanism is used for feeding the sealing ring, the discharge end of the feeding mechanism is provided with a through hole, the size of the through hole is smaller than the size of the sealing ring and can be coaxial with the sealing ring, and also includes a sealing ring guide rod, the sealing ring guide rod is fixedly mounted on the working end of the ejection mechanism and slidably cooperates with the through hole, the sealing ring guide rod is provided with an inclined portion inclined toward a direction away from the ejection mechanism and with a gradually increasing radial size, and the ejection mechanism is located on one side of the sealing ring guide rod.

[0008] The principle of the present invention is: first, place the workpiece with the sealing ring groove on the ejection mechanism; then, when the sealing ring reaches the through hole at the discharge end of the feeding mechanism, the ejection mechanism will drive the sealing ring guide rod to move in the direction close to itself, at which time the sealing ring guide rod will continue to approach the through hole and gradually pass through the through hole, and at the same time, the ejection mechanism will make the workpiece move together with the tail end of the sealing ring guide rod. In this process, the sealing ring will first be clamped into the top of the sealing ring guide rod, and because the size of the through hole is smaller than the size of the sealing ring, the sealing ring will be blocked by the through hole, but the sealing ring guide rod will still penetrate from the through hole. In this way, the discharge end of the feeding mechanism will limit the movement of the sealing ring, and under the continuous movement of the sealing ring guide rod, the sealing ring guide rod will gradually pass through the sealing ring; and due to the existence of the inclined portion, the inner hole of the sealing ring will be continuously enlarged until it slides from the tail of the sealing ring guide rod into the sealing ring groove of the workpiece. After the workpiece and the sealing ring are assembled, the ejection mechanism and the ejection mechanism will drive the workpiece and the sealing ring guide rod to retreat. When the top of the sealing ring guide rod exits the through hole, the subsequent sealing ring will be sent to the through hole again, and the ejection mechanism will be replaced with another workpiece to be processed and the above steps will be repeated. The feeding mechanism can use a vibration plate.

[0009] In the present invention, the expansion method of the sealing ring does not require a complex execution structure. Only a sealing ring guide rod and a mutually cooperating push-in mechanism and ejection mechanism are required to complete the feeding, expansion and assembly of the sealing ring, which greatly reduces the complexity of the equipment and improves the overall fault tolerance of the equipment. Moreover, after the sealing ring guide rod exits the through hole at the discharge end of the feeding mechanism, the sealing ring will automatically fill in the through hole, so that there is no need to manually install the sealing ring on the processing station or the expansion mechanism, thereby realizing the automation of the sealing ring assembly process.

[0010] It is worth mentioning that the expansion device in the prior art will give the sealing ring installed thereon a momentary tension when starting, which is easy to cause damage to the sealing ring. In the present invention, the sealing ring guide rod is gradually inserted into the sealing ring, and the design of the inclined portion allows the inner hole of the sealing ring to be gradually expanded, avoiding momentary large-scale expansion and further reducing damage to the sealing ring; and the way the sealing ring moves on the surface of the sealing ring guide rod can prevent the sealing ring from being offset or tilted.

[0011] Preferably, the inclined portion is a frustum-shaped structure. The frustum-shaped structure may be a prism, a truncated cone, or a trapezoidal frustum, so as to adapt to sealing rings with different inner hole shapes. Among them, sealing rings with circular inner holes are more commonly used, so the inclined portion can be designed to be frustum-shaped. In this way, the inner hole of the sealing ring can fit the surface of the inclined portion as much as possible, so that the force applied to the sealing ring during the movement on the sealing ring guide rod is more uniform, reducing the risk of excessive local force, thereby reducing the probability of damage to the sealing ring.

[0012] It is worth mentioning that the smooth transition characteristics of the frustum-shaped structure make the movement of the sealing ring on the sealing ring guide rod smoother, and there will be no jamming and stopping due to sudden changes in radial dimensions, ensuring that the sealing ring can slide smoothly into the sealing ring groove of the workpiece.

[0013] Preferably, a groove is provided at one end of the inclined portion facing the ejection mechanism. In the prior art, the sealing ring installation method usually does not restrict the placement position of the workpiece, which may cause the workpiece to tilt or shift, further affecting the installation accuracy and sealing performance of the sealing ring. The present invention provides a groove on the inclined portion so that the workpiece and the sealing ring guide rod on the ejection mechanism can be accurately positioned. The ejection mechanism can first allow the workpiece to be inserted into the groove, and then push the workpiece so that the workpiece and the sealing ring guide rod move synchronously toward the sealing ring. In this way, the workpiece and the sealing guide rod can have better coaxiality, ensuring that the sealing ring falls accurately into the workpiece sealing groove.

[0014] Preferably, it also includes a clamping mechanism, which is arranged between the ejection mechanism and the discharge end of the loading mechanism, and the clamping mechanism includes a first driving device and a clamping claw installed on the first driving device, and two clamping claws are arranged opposite to each other, and half holes are arranged on the opposite surfaces of the clamping claws, and the half holes can be slidably matched with the sealing ring guide rod, and the two opposite half holes form a guide hole, and the guide hole is coaxial with the through hole. After the clamping mechanism is set up, the efficiency of sealing ring installation can be effectively improved. The specific operating principle is as follows: first, the two clamping claws are closed, and the sealing ring guide rod is inserted from the guide hole until its top end clamps the sealing ring at the discharge end of the feeding mechanism; then, the clamping claws are released, and the sealing ring guide rod will move with the sealing ring in the direction of the ejection mechanism, and stop moving after the sealing ring is away from the clamping claws; then, the workpiece is placed on the ejection mechanism, and the clamping claws are closed again; then, the ejection mechanism and the ejection mechanism simultaneously drive the workpiece and the sealing ring guide rod to move toward the discharge end of the feeding mechanism. At this time, the workpiece on the ejection mechanism is close to the tail of the sealing ring guide rod; then, because the clamping claws are In the closed state, the sealing ring guide rod will pass through the guide hole, so the sealing ring originally sleeved on the surface of the sealing ring guide rod will be squeezed and pushed by the clamping claws, so that the sealing ring moves along the surface of the sealing ring guide rod and is stretched, and finally slides from the tail of the sealing ring guide rod into the sealing ring groove of the workpiece. It is worth mentioning that in this process, as the sealing ring guide rod moves toward the discharge end of the feeding mechanism, its top end will clamp a new sealing ring at the discharge end of the feeding mechanism again; finally, the clamping claw is released again, so that the sealing ring guide rod and the workpiece with the sealing ring installed return to their original position together, and a new sealing ring will be clamped on the sealing ring guide rod. Then the next cycle is carried out.

[0015] In this way, the movement stroke of the sealing ring guide rod can be effectively shortened, and the sealing ring guide rod can complete the sealing ring loading and unloading actions at the same time, so that there is always a sealing ring to be installed on the sealing ring guide rod, which effectively improves the installation efficiency. The guide hole in the clamping mechanism ensures the stability of the sealing ring guide rod during the movement process, avoiding damage to the sealing ring or inaccurate installation position caused by unstable movement. Similarly, the sealing ring guide rod can be accurately positioned on the sealing ring at the discharge end of the feeding mechanism, ensuring the accuracy of the sealing ring and the sealing ring guide rod in the matching process.

[0016] Preferably, the discharge end of the feeding mechanism is further provided with a feeding trough, the through hole is provided at the end of the feeding trough, and the feeding trough and the sealing ring guide rod are perpendicular to each other. The design of the feeding trough ensures the accurate guidance of the sealing ring before entering the through hole, reduces the deviation of the sealing ring during the movement, improves the feeding accuracy of the sealing ring, and also enables the sealing ring to be quickly positioned at the through hole, ensuring the accurate matching between the sealing ring guide rod and the sealing ring.

[0017] The width of the feeding trough is the same as the size of the sealing ring. In this way, the sealing rings can only fall one by one into the through hole at the end of the feeding trough, avoiding accumulation, thereby improving the orderliness and reliability of the sealing ring feeding and installation matching process.

[0018] Preferably, the ejection mechanism comprises a second driving device and a push rod having one end fixedly connected to the working end of the second driving device, the push rod can move axially under the control of the second driving device, and the other end of the push rod is fixedly connected to the sealing ring guide rod. In this way, the axial movement of the push rod can accurately control the position of the sealing ring guide rod, thereby improving the stability and accuracy of the sealing ring during the loading and unloading process at the sealing ring guide rod, and ensuring the sealing performance of the sealing ring and the workpiece.

[0019] Preferably, the ejection mechanism includes a third driving device and an ejection part fixedly connected to the working end of the third driving device, the ejection part can perform axial movement under the control of the third driving device, and a discharge trough is provided at the upper end of the ejection part, and the motion trajectory of the discharge trough is the same as the motion trajectory of the sealing ring guide rod. Such a design simplifies the operation process, and the operator or the discharge mechanism only needs to place the workpiece on the ejection mechanism, and then the installation of the sealing ring is completed through the coordinated work of the ejection mechanism and the ejection mechanism, which reduces the operation steps and improves the production efficiency. Moreover, since the motion trajectory of the discharge trough is the same as the motion trajectory of the sealing ring guide rod, the workpiece can always be located at the tail of the sealing ring guide rod, thereby ensuring that the sealing ring is accurately docked with the sealing ring groove of the workpiece during the installation process, thereby improving the installation accuracy of the sealing ring.

[0020] Preferably, the size of the through hole is the same as the maximum size on the inclined portion. In this way, the sealing ring guide rod can move unhindered at the discharge end of the feeding mechanism, making the movement of the sealing ring guide rod smoother, avoiding vibration or shaking when it cooperates with the sealing ring, and ensuring the accuracy of the equipment. In addition, since the size of the sealing ring is larger than the size of the through hole, the sealing ring cannot pass through the through hole, so that the sealing ring can only move along the surface of the sealing ring guide rod, ensuring the correct position of the sealing ring during the movement.

[0021] Preferably, a baffle is further included, the baffle being fixedly arranged on the material chute to cover the material chute, the baffle being provided with a notch, the notch being coaxial with the through hole, and the size of the notch being larger than the size of the sealing ring. The baffle can prevent the sealing ring from falling out of the material chute during movement, ensuring the orderly falling of the sealing ring and preventing foreign matter from entering the material chute. The notch is provided to ensure that the sealing ring guide rod will not collide with the baffle during movement, thereby ensuring the safety of the equipment.

[0022] To sum up, such an automatic sealing ring assembly machine, through the sealing ring guide rod design and the matching ejection and ejection mechanism, realizes the full automation of the sealing ring assembly process, which not only simplifies the equipment structure and reduces the failure rate, but also effectively avoids the instantaneous tension damage to the sealing ring caused by the traditional method, ensures the accuracy and safety of the sealing ring assembly, and improves the production efficiency and product quality.

[0036] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Reference Figure 1 and Figure 3 As shown, an automatic sealing ring assembly machine includes a feeding mechanism 1 and an ejection mechanism 2 and an ejection mechanism 3 arranged on both sides of the feeding mechanism 1. The feeding mechanism 1 is used for feeding the sealing ring 6. A through hole 11 is provided at the discharge end of the feeding mechanism 1. The size of the through hole 11 is smaller than the size of the sealing ring 6 and can be coaxial with the sealing ring 6. It also includes a sealing ring guide rod 4, which is fixedly mounted on the working end of the ejection mechanism 3 and slidably cooperates with the through hole 11. The sealing ring guide rod 4 is provided with an inclined portion 41 which is inclined toward a direction away from the ejection mechanism 3 and has a gradually increasing radial size. The ejection mechanism 2 is located on one side of the sealing ring guide rod 4.

[0038] The principle of the present invention is as follows: first, the workpiece 7 with the sealing ring groove is placed on the ejection mechanism 2; then, when the sealing ring 6 reaches the through hole 11 at the discharge end of the feeding mechanism 1, the ejection mechanism 3 drives the sealing ring guide rod 4 to move in the direction close to itself, at which time the sealing ring guide rod 4 will continue to approach the through hole 11 and gradually pass through the through hole 11, and at the same time, the ejection mechanism 2 will make the workpiece 7 move together with the tail end of the sealing ring guide rod 4. In this process, the sealing ring 6 will first be clamped into the top of the sealing ring guide rod 4, and because the size of the through hole 11 is smaller than the size of the sealing ring 6, the sealing ring 6 will be blocked by the through hole 11, but the sealing ring guide rod 4 will still penetrate through the through hole 11. In this way, the discharge end of the feeding mechanism 1 will limit the movement of the sealing ring 6, and under the continuous movement of the sealing ring guide rod 4, the sealing ring guide rod 4 will gradually pass through the sealing ring 6; and due to the existence of the inclined portion 41, the inner hole of the sealing ring 6 will be continuously expanded until it slides from the tail of the sealing ring guide rod 4 into the sealing ring groove of the workpiece 7. After the workpiece 7 and the sealing ring 6 are assembled, the ejection mechanism 2 and the ejection mechanism 3 will drive the workpiece 7 and the sealing ring guide rod 4 to retreat. When the top end of the sealing ring guide rod 4 exits the through hole 11, the subsequent sealing ring 6 will be sent to the through hole 11 again, and the above steps will be repeated after the ejection mechanism 2 is replaced with another workpiece 7 to be processed. The feeding mechanism 1 can use a vibrating plate.

[0039] In the present invention, the expansion method of the sealing ring 6 does not require a complex execution structure. Only a sealing ring guide rod 4 and a mutually cooperating push-in mechanism 2 and ejection mechanism 3 are required to complete the feeding, expansion and assembly of the sealing ring 6, which greatly reduces the complexity of the equipment and improves the overall fault tolerance of the equipment. Moreover, after the sealing ring guide rod 4 exits the through hole 11 at the discharge end of the feeding mechanism 1, the sealing ring 6 will automatically fill in the through hole 11, so that there is no need to manually install the sealing ring 6 on the processing station or the expansion mechanism, thereby realizing the automation of the assembly process of the sealing ring 6.

[0040] It is worth mentioning that the expansion device in the prior art will give the sealing ring 6 installed thereon a momentary tension when starting, which is easy to cause damage to the sealing ring 6. In the present invention, the sealing ring guide rod 4 is gradually inserted into the sealing ring 6, and the design of the inclined portion 41 allows the inner hole of the sealing ring 6 to be gradually expanded, avoiding momentary large-scale expansion and further reducing damage to the sealing ring 6; and the way the sealing ring 6 moves on the surface of the sealing ring guide rod 4 can prevent the sealing ring 6 from being offset or tilted.

[0041] In addition, refer to Figure 4 As shown, the inclined portion 41 is a frustum-shaped structure. The frustum-shaped structure can be a prism, a truncated cone or a trapezoidal frustum to adapt to the sealing rings 6 with different inner hole shapes. Among them, the sealing ring 6 with a circular inner hole is more commonly used, so the inclined portion 41 can be designed to be a truncated cone. In this way, the inner hole of the sealing ring 6 can fit the surface of the inclined portion 41 as much as possible, so that the force applied to the sealing ring 6 during the movement on the sealing ring guide rod 4 is more uniform, reducing the risk of excessive local force, thereby reducing the probability of damage to the sealing ring 6.

[0042] It is worth mentioning that the smooth transition characteristics of the frustum-shaped structure make the movement of the sealing ring 6 on the sealing ring guide rod 4 smoother, and there will be no jamming or stopping due to sudden changes in radial dimensions, ensuring that the sealing ring 6 can smoothly slide into the sealing ring groove of the workpiece 7.

[0043] In addition, refer to Figure 4 As shown, a groove 42 is provided at one end of the inclined portion 41 facing the push-in mechanism 2. In the prior art, the installation method of the sealing ring 6 usually does not restrict the placement position of the workpiece 7, which may cause the workpiece 7 to be tilted or offset, further affecting the installation accuracy and sealing performance of the sealing ring 6. The present invention provides a groove 42 on the inclined portion 41 so that the workpiece 7 on the push-in mechanism 2 can be accurately positioned with the sealing ring guide rod 4. The push-in mechanism 2 can first allow the workpiece 7 to be inserted into the groove 42, and then push the workpiece 7 so that the workpiece 7 and the sealing ring guide rod 4 move synchronously toward the sealing ring 6. In this way, the workpiece 7 and the sealing guide rod can have better coaxiality, ensuring that the sealing ring 6 falls accurately into the sealing groove 42 of the workpiece 7.

[0044] In addition, refer to Figure 2 As shown, it also includes a clamping mechanism 5, which is arranged between the ejection mechanism 2 and the discharge end of the feeding mechanism 1. The clamping mechanism 5 includes a first driving device 51 and a clamping claw 52 installed on the first driving device 51. Two clamping claws 52 are relatively arranged, and half holes 521 are arranged on the opposite surfaces of the clamping claws 52. The half holes 521 can be slidably matched with the sealing ring guide rod 4. The two opposite half holes 521 form a guide hole, and the guide hole is coaxial with the through hole 11. After the clamping mechanism 5 is set, the installation efficiency of the sealing ring 6 can be effectively improved. The specific operating principle is as follows: first, the two clamping claws 52 are closed, and the sealing ring guide rod 4 is inserted from the guide hole until its top end clamps the sealing ring 6 at the discharge end of the feeding mechanism 1; then, the clamping claws 52 are released, and the sealing ring guide rod 4 will move with the sealing ring 6 in the direction of the ramming mechanism 2, and stop moving after the sealing ring 6 is away from the clamping claws 52; then, the workpiece 7 is placed on the ramming mechanism 2, and the clamping claws 52 are closed again; then, the ramming mechanism 2 and the ejection mechanism 3 simultaneously drive the workpiece 7 and the sealing ring guide rod 4 to move toward the discharge end of the feeding mechanism 1, and at this time, the workpiece 7 on the ramming mechanism 2 is close to the tail of the sealing ring guide rod 4; then, due to the clamping The clamping claw 52 is in a closed state, and the sealing ring guide rod 4 will pass through the guide hole, so that the sealing ring 6 originally sleeved on the surface of the sealing ring guide rod 4 will be squeezed and pushed by the clamping claw 52, ​​so that the sealing ring 6 moves along the surface of the sealing ring guide rod 4 and is stretched, and finally slides from the tail of the sealing ring guide rod 4 into the sealing ring groove of the workpiece 7. It is worth mentioning that in this process, as the sealing ring guide rod 4 moves toward the discharge end of the feeding mechanism 1, its top end will clamp a new sealing ring 6 at the discharge end of the feeding mechanism 1 again; finally, the clamping claw 52 is released again, so that the sealing ring guide rod 4 and the workpiece 7 with the sealing ring 6 installed return to their original positions, and at this time a new sealing ring 6 will be clamped on the sealing ring guide rod 4. Then the next cycle is carried out.

[0045] In this way, the movement stroke of the sealing ring guide rod 4 can be effectively shortened, and the sealing ring guide rod 4 can simultaneously complete the feeding and unloading of the sealing ring 6, so that there is always a sealing ring 6 to be installed on the sealing ring guide rod 4, which effectively improves the installation efficiency. The guide hole in the clamping mechanism 5 ensures the stability of the sealing ring guide rod 4 during the movement process, avoiding damage to the sealing ring 6 or inaccurate installation position caused by unstable movement. Similarly, the sealing ring guide rod 4 can be accurately positioned on the sealing ring 6 at the discharge end of the feeding mechanism 1, ensuring the accuracy of the matching process between the sealing ring 6 and the sealing ring guide rod 4.

[0046] In addition, refer to Figure 2As shown, the discharge end of the feeding mechanism 1 is also provided with a feeding trough 12, and the through hole 11 is provided at the end of the feeding trough 12, and the feeding trough 12 is perpendicular to the sealing ring guide rod 4. The design of the feeding trough 12 ensures the accurate guidance of the sealing ring 6 before entering the through hole 11, reduces the deviation of the sealing ring 6 during the movement, improves the feeding accuracy of the sealing ring 6, and also enables the sealing ring 6 to be quickly positioned at the through hole 11, ensuring the accurate matching of the sealing ring guide rod 4 and the sealing ring 6.

[0047] The width of the feed chute 12 is the same as the size of the sealing ring 6. In this way, the sealing rings 6 can only fall one by one to the through hole 11 at the end of the feed chute 12, avoiding accumulation, thereby improving the orderliness and reliability of the feeding and installation process of the sealing ring 6.

[0048] In addition, refer to Figure 1 As shown, the ejection mechanism 3 includes a second driving device 31 and a push rod 32 with one end fixedly connected to the working end of the second driving device 31. The push rod 32 can move axially under the control of the second driving device 31, and the other end of the push rod 32 is fixedly connected to the sealing ring guide rod 4. In this way, the axial movement of the push rod 32 can accurately control the position of the sealing ring guide rod 4, thereby improving the stability and accuracy of the sealing ring 6 during the loading and unloading process at the sealing ring guide rod 4, and ensuring the sealing performance of the sealing ring 6 and the workpiece 7.

[0049] In addition, refer to Figure 1 As shown, the push-in mechanism 2 includes a third driving device 21 and a push-in portion 22 fixedly connected to the working end of the third driving device 21. The push-in portion 22 can perform axial movement under the control of the third driving device 21. A discharge groove 221 is provided at the upper end of the push-in portion 22. The motion trajectory of the discharge groove 221 is the same as the motion trajectory of the sealing ring guide rod 4. Such a design simplifies the operation process. The operator or the discharge mechanism only needs to place the workpiece 7 on the push-in mechanism 2, and then the installation of the sealing ring 6 is completed through the coordinated work of the push-in mechanism 2 and the ejection mechanism 3, which reduces the operation steps and improves the production efficiency. Moreover, since the motion trajectory of the discharge groove 221 is the same as the motion trajectory of the sealing ring guide rod 4, the workpiece 7 can always be located at the tail of the sealing ring guide rod 4, thereby ensuring that the sealing ring 6 is accurately docked with the sealing ring groove of the workpiece 7 during the installation process, thereby improving the installation accuracy of the sealing ring 6.

[0050] In addition, the size of the through hole 11 is the same as the maximum size on the inclined portion 41. In this way, the sealing ring guide rod 4 can move unhindered at the discharge end of the feeding mechanism 1, making the movement of the sealing ring guide rod 4 smoother, avoiding vibration or shaking when it cooperates with the sealing ring 6, and ensuring the accuracy of the equipment. Moreover, since the size of the sealing ring 6 is larger than the size of the through hole 11, the sealing ring 6 cannot pass through the through hole 11, so that the sealing ring 6 can only move along the surface of the sealing ring guide rod 4, ensuring the correct position of the sealing ring 6 during the movement.

[0051] In addition, refer to Figure 1 and Figure 3 As shown, it also includes a baffle 121, which is fixedly arranged on the material chute 12 to cover the material chute 12, and a notch 122 is arranged on the baffle 121, and the notch 122 is coaxial with the through hole 11, and the size of the notch 122 is larger than the size of the sealing ring 6. The baffle 121 can prevent the sealing ring 6 from falling out of the material chute 12 during movement, ensuring the orderly falling of the sealing ring 6 and preventing foreign matter from entering the material chute 12. The notch 122 is provided to ensure that the sealing ring guide rod 4 will not collide with the baffle 121 during movement, thereby ensuring the safety of the equipment.

[0052] To sum up, such an automatic sealing ring assembly machine, through the design of the sealing ring guide rod 4 and the matching push-in and push-out mechanism, realizes the full automation of the sealing ring 6 assembly process, which not only simplifies the equipment structure and reduces the failure rate, but also effectively avoids the instantaneous tension damage to the sealing ring caused by the traditional method, ensures the accuracy and safety of the sealing ring assembly, and improves the production efficiency and product quality.
