Description

Technical Field

[0001] This application relates to the field of component assembly technology, particularly to the assembly technology of snap rings and E-type retaining rings, and specifically to an assembly mechanism and assembly method. Background Technology

[0002] When components are installed into their corresponding workpieces, they often need to be assembled in a specific posture. For example, during assembly, the component is adjusted to the required posture, and then a drive component is used to push the component towards the corresponding workpiece in that posture until assembly is complete. However, a large space is required during assembly to prevent interference, but a large installation space also results in a long stroke for the component during the pushing process. This makes the component prone to warping, rotation, or other changes in posture during the pushing process, especially for smaller, thinner components, such as E-type retaining rings or E-type retaining rings. These small components are more likely to change posture during the pushing process, thus affecting the assembly with the corresponding workpiece. Summary of the Invention

[0003] The purpose of this application is to provide an assembly mechanism and assembly method that can minimize assembly interference, shorten the stroke of direct component movement, and improve the stability of the component's posture during the movement process.

[0004] To solve the above-mentioned technical problems, this application provides an assembly mechanism that can be used to assemble a first workpiece to a second workpiece. The assembly mechanism includes a pushing component, a picking component, and a positioning component. The positioning component can be used to support the second workpiece. The pushing component includes a receiving seat, a first driving component, and a second driving component.

[0005] The receiving seat is provided with a storage position for placing a first workpiece; the receiving seat can move closer to or away from the positioning component, defined as a first direction being the direction in which the receiving seat moves closer to or away from the positioning component; the receiving seat has a first position and a second position, the second position being closer to the positioning component relative to the first position; the receiving seat is at the first position; the picking component corresponds to the storage position in the thickness direction of the receiving seat; the picking component can move closer to or away from the storage position; the picking component can place the first workpiece to the storage position; the first driving component can drive the receiving seat to move a first distance from the first position along the first direction to the second position;

[0006] The second driving component is directly or indirectly connected to the receiving seat. The second driving component can push the first workpiece on the receiving seat in the second position to move a second distance along the first direction to the assembly position of the second workpiece. The second distance is less than the first distance.

[0007] In this solution, when the assembly mechanism receiving seat is in the first position, the material picking component and the storage position correspond in the thickness direction of the receiving seat. At this time, the material is placed on the receiving seat away from the pushing component, which can avoid interference between the material picking component's material placement action and the pushing component. When the receiving seat is in the second position, the receiving seat abuts against the positioning component, away from the material picking component, avoiding interference from the material picking component in subsequent pushing actions. At the same time, when assembling the first and second workpieces through the pushing component, the first workpiece is not directly pushed to the second workpiece. Instead, the receiving seat containing the first workpiece is first pushed, so that the receiving seat carrying the first workpiece approaches the second workpiece first. In this way, the stroke of the first workpiece moving to the second workpiece will be divided into two stages. In the first stroke stage, the receiving seat carries the first workpiece and moves a first distance to approach the second workpiece. In the second stroke stage, the second driving component pushes the first workpiece alone and moves a second distance to approach and until it is assembled to the second workpiece. The second distance can be set to be less than the first distance, so the stroke of the first workpiece being directly pushed will be shortened, thereby improving the problem of the first workpiece's posture change affecting the assembly due to the excessive stroke during the direct pushing of the first workpiece.

[0008] This solution also provides an assembly method, including:

[0009] Place the first workpiece on the receiving seat;

[0010] Drive the receiving seat to move along a first direction so that the receiving seat carries the first workpiece closer to the second workpiece;

[0011] The first workpiece on the receiving seat is driven to continue moving along the first direction to approach and assemble with the second workpiece, and the second distance is less than the first distance.

[0012] The assembly method divides the movement of the first workpiece into two stages. In the first stroke stage, the receiving seat carries the first workpiece a first distance to approach the second workpiece. In the second stroke stage, the receiving seat no longer moves, but the second driving component pushes the first workpiece a second distance to approach and assemble it with the second workpiece. The second distance can be set to be less than the first distance, so the stroke of the first workpiece being directly pushed will be shortened, thereby improving the problem of the first workpiece's posture change affecting the assembly due to the excessive stroke during the direct pushing of the first workpiece.

[0013] This solution also provides an assembly method, including: preparing the snap ring and the valve core;

[0014] The preparation of the snap ring includes:

[0015] The vibratory feeder of the feeding assembly feeds multiple stacked snap rings;

[0016] The cutting seat of the material picking assembly picks up one of the stacked snap rings at a time;

[0017] The gripping structure of the material handling component grips one of the retaining rings at a time to place the retaining ring on the receiving seat;

[0018] The preparation of the valve core includes:

[0019] The valve core is pressed down by the pressing component, so that the valve core is supported between the supporting component and the pressing component, and the assembly position of the valve core corresponds to the position of the snap ring;

[0020] Drive the receiving seat to move along a first direction so that the receiving seat carries the snap ring close to the valve core;

[0021] The snap ring on the receiving seat is driven to continue moving along the first direction to approach and assemble into the assembly position of the valve core.

[0022] This assembly method divides the movement of the retaining ring into two stages. In the first stage, the receiving seat carries the retaining ring to move close to the valve core. In the second stage, the second driving component pushes the retaining ring to move close to and until it is assembled with the valve core. This shortens the stroke of the retaining ring being directly pushed, thereby improving the problem of the retaining ring's posture change affecting the assembly due to the excessive stroke during the direct pushing process.

[0054] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] In the embodiments of this application, the terms "first," "second," etc., are used only to distinguish the same or similar features, and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0056] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the assembly mechanism from a first-view perspective in one embodiment of this application; Figure 2 for Figure 1 Enlarged diagram of part A in the middle; Figure 3 for Figure 1 A schematic diagram of the assembly mechanism from a second-view perspective; Figure 4 for Figure 3 Enlarged diagram of part B in the middle; Figure 5 for Figure 1 A schematic diagram of the structure of the first workpiece 0A conveyed by the assembly mechanism in the embodiment.

[0057] The assembly mechanism in this embodiment is used to assemble the first workpiece 0A onto the second workpiece 0B. In this embodiment, the first workpiece 0A is a retaining spring. Figure 5 As shown, the second workpiece 0B in this embodiment is a shaft component, such as... Figure 4 As shown, the shaft component is a valve core 0B', which includes a valve core body 0B1 and a rod portion 0B2 located below the valve core body 0B1.

[0058] The assembly mechanism in this embodiment includes a feeding component 10, a picking component 30, a pushing component 20, and a positioning component 40. The feeding component 10 is used to feed the first workpiece 0A, the picking component 30 is used to pick up the first workpiece 0A and place it onto the pushing component 20, the positioning component 40 is used to support and position the second workpiece 0B, and the pushing component 20 is used to push the first workpiece 0A to gradually approach and finally assemble it onto the second workpiece 0B.

[0059] For ease of understanding, the following will describe in detail the feeding component 10, the picking component 30, the pushing component 20, and the positioning component 40 of the assembly mechanism.

[0060] like Figure 1 , 2As shown, the feeding assembly 10 in this embodiment specifically includes a vibratory feeder. When the first workpiece 0A is assembled to the second workpiece 0B, the first workpiece 0A needs to be close to the second workpiece 0B in a predetermined posture to complete the assembly. Therefore, the feeding assembly 10 has a posture correction function for the first workpiece 0A, so that multiple first workpieces 0A are adjusted to the required assembly posture. After multiple first workpieces 0A are loaded into the vibratory feeder, their postures can be unified under the screening action of the vibratory feeder. Figure 5 The first workpiece 0A shown is a retaining circlip, specifically an E-type retaining circlip. This retaining circlip is just one example; any component that needs to be assembled with the second workpiece 0B in a specific posture can use this assembly mechanism, such as an E-type retaining ring. Specifically, as... Figure 5 As shown, the retaining ring, which is the first workpiece 0A, is a ring structure with an opening 0Aa. During assembly, the thickness direction of the retaining ring is parallel to the axial direction of the rod 0B2, and the retaining ring needs to be clamped onto the second workpiece 0B with its opening 0Aa facing the position to be assembled on the rod 0B2 of the second workpiece 0B, so as to complete the press-fit assembly of the second workpiece 0B.

[0061] Figure 2 In the middle, the vibratory feeder of the feeding assembly 10 has a circular track 101, such as Figure 6 As shown, Figure 6 for Figure 2 Enlarged schematic diagram of part J in the middle. The annular track 101 is a Y-shaped contour track with snap rings, that is, the cross-sectional shape of the annular track 101 perpendicular to the conveying direction is approximately T or Y-shaped, with the vertical part of the T or Y shape facing upwards. The vertical part is the first track limiting structure 1012. The opening 0Aa of the snap ring faces downwards to be locked onto the first track limiting structure 1012. In this way, only snap rings with the opening 0Aa facing downwards can enter the annular track 101. Others will fall off and be vibrated and fed again. After vibration, the first workpiece 0A that can be locked into the annular track 101 of the vibrating plate will continue to be conveyed downstream. In this way, the first workpiece 0A conveyed will have a uniform posture, ensuring that the opening 0Aa of the first workpiece 0A conveyed by the annular track 101 locked into the vibrating plate faces the same direction.

[0062] In addition, the vibratory feeder of the feeding assembly 10 in this embodiment also includes a linear vibration track 102, which can be combined with... Figures 7 to 9 understand, Figure 7 for Figure 1 The structural diagram of the assembly mechanism from a third-person perspective does not show the main body of the vibratory feeder, but only the straight vibration track 102. Figure 8 for Figure 7 Enlarged schematic diagram of part C in the middle; Figure 9 for Figure 8 Enlarged schematic diagram of part D in the middle; Figure 10 for Figure 7 A magnified view of the K-section.

[0063] The vibratory feeder's annular track 101 has a first discharge end 1011, and the linear vibratory track 102 has a feed end and a second discharge end 10221. The feed end of the linear vibratory track 102 is connected to the first discharge end 1011 of the annular track 101, and the two can have a small gap. After the first workpiece 0A is output from the annular track 101, it will continue to be conveyed to the linear vibratory track 102. The linear vibratory track 102 is as follows: Figure 10 As shown, the principle is the same as that of the circular track 101, and it is also a contour structure of the first workpiece 0A. It can include a second track limiting structure 102a. The first workpiece 0A can be engaged with the second track limiting structure 102a through its opening 0Aa, that is, the second track limiting structure 102a is inserted into the interior of the first workpiece 0A through the opening 0Aa. The vertical vibration track 102 includes an inclined track section 1021 and a vertical track section 1022, as shown. Figure 7 As shown, one end of the inclined track section 1021 is connected to the circular track 101. The inclined track section 1021 and the vertical track section 1022 are connected, and the two can be transitioned through the arc track section 1023. The lower end of the vertical track section 1022 serves as the second discharge end 10221. In this way, the first workpiece 0A conveyed by the circular track 101 has its opening 0Aa facing downwards. After adjustment by the straight vibrating track 102, the first workpiece 0A can be discharged downwards with its opening 0Aa facing the horizontal direction (specifically, the first direction described below). Figure 5 As shown, when the first workpiece 0A is a ring-shaped retaining spring, it has an outer contour and an inner contour. Both the linear vibration track 102 and the ring track 101 can be contoured structures inside the first workpiece 0A, meaning the contour of the track is the same as the inner contour of the first workpiece 0A, to better match the first workpiece 0A, ensuring that all first workpieces 0A inserted into the track have the same posture and can maintain posture stability during the conveying process. Furthermore, there is a transition section between the first track limiting structure 1012 and the second track limiting structure 102a. The volume of the second track limiting structure 102a can be set to be larger than the volume of the first track limiting structure 1012. The first track limiting structure 1012 is used to initially control the opening orientation of the first workpiece 0A, and the second track limiting structure 102a is used to correct the opening orientation of the first workpiece 0A, improving the accuracy and consistency of the opening orientation of the first workpiece 0A.

[0064] The first discharge end 1011 of the circular track 101 can be equipped with a contouring part (not shown in the figure) to mimic the shape of the first workpiece 0A. Before the first workpiece 0A enters the straight vibration track 102 from the circular track 101, it can be adjusted and regulated by the contouring part to ensure that all the first workpieces 0A entering the straight vibration track 102 maintain the same posture, that is, the opening 0Aa direction is the same.

[0065] You can continue to refer to this. Figures 11 to 13 understand, Figure 11 for Figure 1 A schematic diagram of the assembly mechanism from a fourth-person perspective; Figure 12 for Figure 11 Enlarged schematic diagram of part E in the middle; Figure 13 for Figure 12 Enlarged schematic diagram of part F in the middle.

[0066] In some embodiments, the feeding assembly 10 may further include a storage structure 1031, through which multiple first workpieces 0A conveyed from the vibratory feeder of the feeding assembly 10 can be stacked along a fourth direction. In this embodiment, the fourth direction is the height direction of the storage structure 1031, which is also the vertical direction. Figure 8 , 12 13. It is understood that the feeding component 10 includes a storage seat 103, which includes a storage base 1032 and a storage structure 1031 disposed on the storage base 1032. The storage structure 1031 includes a columnar structure, and the cross-section of the columnar structure can be a contoured structure inside the first workpiece 0A, that is, the outer contour of the cross-section of the storage structure 1031 is the same as the inner contour of the first workpiece 0A. In this way, the first workpiece 0A can be inserted into the storage structure 1031, that is, it can only move along the height direction of the storage structure 1031. Of course, the outer contour of the cross-section of the columnar structure does not necessarily have to be the same as the inner contour of the first workpiece 0A. Especially when the inner contour of the first workpiece 0A is an irregular shape, as long as the storage structure 1031 can restrict the first workpiece 0A from moving along the second direction described below, the second direction is the direction perpendicular to the stacking of multiple first workpieces 0A. The second direction is the material picking direction and the material feeding direction of the cutting seat 301.

[0067] For example, the profile of the cross-section of the columnar structure of the storage structure 1031 includes, for example, arc-shaped segments and rectangular segments, or arc-shaped segments and trapezoidal segments, with the opening of the arc-shaped segment connecting to the rectangular or trapezoidal segment. (Combined with...) Figure 5 In this embodiment, the inner hole of the first workpiece 0A includes a circular hole 0Ab connected to the opening 0Aa. Two concave holes 0Ac are also provided on the side opposite to the opening 0Aa. The circular hole 0Ab is located in the middle of the first workpiece 0A, and the outer contour of the first workpiece 0A is a circle with a notch. At this time, the arc-shaped segment of the cross-section of the columnar structure of the storage structure 1031 can be adapted to the hole wall corresponding to the circular hole 0Ab, and the trapezoidal segment can be adapted to the hole wall corresponding to the gradually expanding opening 0Aa. Of course, the trapezoidal segment can also be a rectangular segment, as long as the width of the rectangular segment is not less than the narrowest point of the opening 0Aa. Therefore, when the first workpiece 0A slides downward into the columnar structure of the storage structure 1031, the first workpiece 0A cannot detach from the columnar structure of the storage structure 1031 along the second direction.

[0068] Clearly, the material storage structure 1031, the aforementioned annular track 101, and the linear vibration track 102 are all contour-following structures inside the first workpiece 0A. One side of the material storage structure 1031 extending along the height direction is connected to the material storage base 1032. The two can be integrally set, that is, the material storage structure 1031 can be a protruding part of the material storage base 1032, or the material storage structure 1031 can be a separate structure from the material storage base 1032.

[0069] Let's look again. Figure 8 The vertical track section 1022 of the vertical vibrating track 102 is connected to the storage structure 1031, specifically, the second discharge end 10221 of the vertical track section 1022 is connected to the storage structure 1031. The first workpiece 0A, which is stuck on the vertical track section 1022, will fall onto the storage structure 1031 under the action of gravity. That is, the opening 0Aa of the retaining spring of the first workpiece 0A continues to be stuck onto the storage structure 1031, thus stacking together along the height direction of the storage structure 1031. Figure 8 , 13 As shown, the storage structure 1031 stores a stack of first workpieces 0A. It is understood that the number of first workpieces 0A stored in the storage structure 1031 is limited. The feeding speed can be controlled according to the assembly speed requirements to ensure that the storage structure 1031 can meet the storage needs. Alternatively, a sensor can be installed to monitor the number of first workpieces 0A stored in the storage structure 1031. This way, when the number of first workpieces 0A stored in the storage structure 1031 is about to exceed the storage capacity, the vibratory feeder can be controlled to slow down or stop feeding altogether. The sensor could be, for example, an infrared sensor.

[0070] The above describes the feeding component 10. After feeding is complete, material needs to be removed. Please refer to the material removal component 30.

[0071] like Figure 8 , 9 As shown, the material handling assembly 30 in this embodiment includes a cutting seat 301 and a driving component for moving the cutting seat 301, which can be defined as a third driving component 302. The third driving component 302 is used to drive the cutting seat 301 to reciprocate along a second direction to reach a first material handling position and a second material handling position. The third driving component 302 is, for example, a cylinder, but it can also be other structures, such as a motor and a lead screw assembly. A cylinder can provide reliable driving force and has a low cost. Other driving components mentioned below have similar structures to the third driving component 302, and can also be cylinders or other structures. They will not be discussed one by one, but can be understood by referring to the third driving component 302.

[0072] In this application, when the cutting seat 301 is in the first material picking position, the material trough 301a and the material storage structure 1031 are arranged opposite each other along the fourth direction, which facilitates the straight material picking of the first driving component 302 in the fourth direction and improves the material picking stability.

[0073] In this application, the distance between the bottom 1033 of the storage structure 1031 and the bottom 301a1 of the material trough 301a in the fourth direction is less than the thickness of two first workpieces 0A and greater than the thickness of one first workpiece 0A. This ensures that only one first workpiece 0A can fall into the material trough 301a, and the fallen first workpiece 0A can be completely detached from the storage structure 1031. Furthermore, the depth of the material trough 301a can be set to be no greater than the thickness of one first workpiece 0A, which can reduce the adverse effects of interference and friction during the cutting process and ensure that the second retaining spring stacked near the cutting seat is not subjected to excessive friction during cutting.

[0074] Specifically, in this embodiment, the fourth direction is the vertical direction. The cutting seat 301 of the material taking component 30 is located below the aforementioned material storage structure 1031. The material storage structure 1031 and the cutting seat 301 can contact one side of the material groove 301a, which in this embodiment is contact with the upper surface of the cutting seat 301a. Alternatively, there can be a very small gap between the material storage structure 1031 and the cutting seat 301, which is less than the thickness of a first workpiece 0A. Figure 9 As shown, the upper surface of the cutting seat 301 is provided with a material groove 301a, which is used to accommodate the first workpiece 0A. The material groove 301a is a contour groove that roughly matches the overall outline of the first workpiece 0A. The first workpiece 0A can be embedded in the material groove 301a. The depth of the material groove 301a can be the same as the thickness of the first workpiece 0A, or slightly less than the thickness of the first workpiece 0A. In this embodiment, the material groove 301a is projected as a circle along the fourth direction, that is, the sidewall of the material groove 301a is a cylindrical wall.

[0075] contrast Figure 8 , 13 understand, Figure 8 In the process, the material groove 301a of the cutting seat 301 is in the material storage state, that is, the inside of the material groove 301a contains the first workpiece 0A. Figure 8 The left-right direction is the second direction. After the first workpiece 0A is taken out, the cutting seat 301 can move to the right under the action of the third driving component 302, achieving... Figure 13The position is such that the lower end of the material trough 301a and the storage structure 1031 are aligned in the height direction, that is, aligned in the fourth direction in this embodiment. Then the first workpiece 0A at the bottom of the storage structure 1031 will fall into the material trough 301a. The first workpiece 0A completely detaches from the storage structure 1031 in the height direction. The third driving component 302 then drives the cutting seat 301 to move to the left in the opposite direction. The cutting seat 301 will carry the first workpiece 0A that has fallen into the material trough 301a to the right. When the bottom first workpiece 0A falls into the material trough 301a, the multiple first workpieces 0A on the storage structure 1031 move down accordingly. The first workpiece 0A that moves down to the bottom will contact the upper surface of the cutting seat 301 and be supported on the upper surface of the cutting seat 301, so as to wait for the next time the cutting seat 301 moves to the right and falls into the material trough 301a again. As can be seen from the working process, since the cutting seat 301 needs to move back and forth along the second direction, a small gap is set between the cutting seat 301 and the storage structure 1031 to reduce wear.

[0076] In some embodiments, the storage structure 1031 includes a columnar structure extending in a fourth direction. A plurality of first workpieces 0A can be stacked on the storage structure 1031 along the fourth direction. A gap may exist between the columnar structure and the upper surface of the cutting seat 301, and this gap is equal to or slightly greater than the thickness of one first workpiece 0A (the sum of this gap and the depth of the material groove 301a must be less than the thickness of two first workpieces 0A). The second direction actually includes the material-taking direction where the cutting seat 301 moves to bring the material groove 301a closer to the storage structure 1031, and the material-feeding direction where the cutting seat 301 moves to move the material groove 301a away from the storage structure 1031. The material-feeding direction and the material-taking direction are... Figure 12 left and right direction in center.

[0077] In some embodiments, the depth of the material trough 301a in the fourth direction is less than the thickness of a first workpiece 0A, the distance between the bottom 1033 of the storage structure 1031 and the top 3010 of the cutting seat 301 in the fourth direction is less than the thickness of a first workpiece 0A, the fourth direction is perpendicular to the first direction, the storage structure 1031 includes a columnar structure extending in the fourth direction, the profile of the cross-section of the columnar structure includes an arc segment and a rectangular segment, or includes an arc segment and a trapezoidal segment; the opening of the arc segment connects with the rectangular segment or the trapezoidal segment, the diameter of the arc segment is greater than the maximum width of the rectangular segment or the trapezoidal segment, which can realize the first workpiece 0A being stuck in the first direction; or, the storage structure 1031 of the storage seat 103 is also provided with a limiting structure (not shown in the figure) that restricts the movement of the first workpiece 0A in the picking direction, because the storage... There is a gap between the columnar structure of structure 1031 and the cutting seat 301 equal to the thickness of the first workpiece 0A. The first workpiece 0A will fall along the storage structure 1031 to the upper surface of the cutting seat 301. It is equivalent to the bottom first workpiece 0A not being restricted by the columnar structure of the storage structure 1031. In order to prevent the cutting seat 301 from moving the first workpiece 0A before the material groove 301a reaches directly below the first workpiece 0A during the movement of the cutting seat 301 in the material picking direction, a limiting structure can be set to restrict the movement of the first workpiece 0A in the material picking direction. The limiting structure can be a contour groove structure of the outer contour of the first workpiece 0A. When the cutting seat 301 reaches directly below the first workpiece 0A, the first workpiece 0A falls into the material groove 301a and the material picking is completed. The limiting structure does not restrict the movement of the first workpiece 0A in the material feeding direction. In this cutting method, the depth of the material groove 301a is set to be less than the thickness of the first workpiece 0A. In this way, the first workpiece 0A protrudes from the material groove 301a, which facilitates the subsequent gripping structure 303 to grip the material from the material groove 301a.

[0078] As can be seen, in this embodiment, the material picking component 30, through the reciprocating motion of the cutting seat 301, can pick up only one first workpiece 0A at a time. Especially for smaller and thinner types of first workpiece 0A, known material picking methods tend to pick up two or more at a time, thus affecting installation. However, in this embodiment, the material picking seat 301 can pick up one at a time, thereby improving the accuracy of material picking and avoiding picking up too many at once, which would affect installation.

[0079] The material handling component 30 in this embodiment may further include a gripping structure 303 and a fourth driving component 304. The gripping structure 303 is specifically as follows: Figure 11 , 12The vacuum adsorption structure shown has a fourth driving component 304 that can drive the gripping structure 303 to move along a third direction. In this embodiment, the third direction is parallel to the stacking direction of the first workpiece 0A (i.e., the fourth direction), so it can move up and down. In this embodiment, the up and down direction is the vertical direction. When the cutting seat 301 cuts off a first workpiece 0A and moves away from the storage structure 1031 to directly below the gripping structure 303, the fourth driving component 304 can drive the gripping structure 303 to move downward to approach the first workpiece 0A and adsorb and grip the first workpiece 0A. Then, the fourth driving component 304 can drive the gripping structure 303 to move upward to move away from the cutting seat 301. The material handling component 30 also includes a fifth driving component 305. In this embodiment, the first direction and the second direction are parallel, and the fifth direction is perpendicular to the first direction and the second direction. That is, after the gripping structure 303 adsorbs and grips the first workpiece 0A, the fifth driving component 305 can drive the gripping structure 303 to move along the fifth direction so as to translate and transport the gripped and adsorbed first workpiece 0A to the following pushing component 20 in the horizontal plane.

[0080] The gripping structure 303 is a vacuum adsorption structure, which facilitates the gripping of the first workpiece 0A in the material tank 301a. This is especially true for small parts, where vacuum adsorption is more reliable and less likely to damage the first workpiece 0A. Of course, the gripping structure 303 is not limited to a vacuum adsorption structure; it could include grippers or similar devices for snap-fit ​​gripping. This embodiment does not limit the specific structure of the gripping structure 303. Furthermore, a second adsorption hole (not shown in the figure) can be provided at the bottom of the material tank 301a of the cutting seat 301. When the first workpiece 0A is located in the material tank 301a, the second adsorption hole can vacuum-adsorb the first workpiece 0A, further ensuring that the first workpiece 0A maintains its posture after falling into the material tank 301a. When the gripping structure 303 grips the first workpiece 0A in the material tank 301a, the gripping adsorption force can be greater than the adsorption force of the second adsorption hole. Alternatively, the vacuum of the second adsorption hole in the material tank 301a can be closed during gripping to remove the vacuum adsorption force, thus facilitating gripping.

[0081] In this embodiment, the fifth direction in which the fifth driving component 305 moves and the second direction in which the cutting seat 301 moves are both horizontal and perpendicular to each other. Therefore, the third and second directions are not limited to being perpendicular; they only need to be mutually non-interfering. Here, the second and third directions are perpendicular to each other, which facilitates the arrangement of the cutting seat 301 and the following pushing assembly 20, resulting in a compact structure.

[0082] In the above embodiments, the feeding assembly 10 achieves reliable adjustment of the posture of the first workpiece 0A by setting up an annular track 101 and a linear vibration track 102, and facilitates the material picking up by the cutting seat 301 in the horizontal direction. In some embodiments, the feeding assembly 10 may not have the linear vibration track 102, and the first workpiece 0A conveyed by the annular track 101 is stacked in the horizontal direction, that is, the fourth direction is horizontal, and the opening 0Aa of the first workpiece 0A faces downward. In this case, the first workpiece 0A can be directly picked up by, for example, a gripping structure and conveyed to the pushing assembly 20. In this case, the first workpiece 0A picked up can be visually inspected one by one by a camera to perform position detection and correction, ensuring that the opening 0Aa of the first workpiece 0A is accurate before installation. In comparison, the feeding accuracy of the feeding assembly 10 and the picking accuracy of the picking assembly 30 are easier to ensure, and the control cost is lower.

[0083] Next, let's look at the pusher assembly 20.

[0084] Please continue to refer to this. Figure 3 and combined Figures 14 to 17 As shown, Figure 14 for Figure 3 A schematic diagram of the structure of the middle positioning component 40 after the pressing component presses down the second workpiece 0B; Figure 15 for Figure 14 Enlarged view of the G-section; Figure 16 for Figure 14 A schematic diagram showing the partial assembly and cooperation of the pusher assembly 20 and the positioning assembly 40; Figure 17 for Figure 16 Another perspective of the schematic diagram does not show the mounting base 50.

[0085] The feeding assembly 20 in this embodiment includes a receiving seat 203, a first driving component 201, and a second driving component 202.

[0086] The fifth driving component 305 of the aforementioned material picking component 30 drives the gripping structure 303 and the fourth driving component 304 to move together along the fifth direction. When they move to directly above the receiving seat 203, the fourth driving component 304 drives the gripping structure 303 to move downward along the sixth direction to place the first workpiece 0A onto the receiving seat 203 located at the first position. That is, the receiving seat 203 is at the first position, and the material picking component 30 and the storage position 2032 correspond in the thickness direction of the receiving seat 203. Then, the fourth driving component 304 moves upward, and the fifth driving component 305 drives the gripping structure 303 and the fourth driving component 304 to move together in the opposite direction along the fifth direction to move away from the pushing component 20, so that the next material picking action from the cutting seat 301 can be performed.

[0087] like Figure 15As shown, the second workpiece 0B is positioned on the assembly position of the assembly mechanism. The first driving component 201 of the pushing component 20 can drive the receiving seat 203 located at the first position to move along the first direction to approach or move away from the second workpiece 0B. That is, the first direction is the direction in which the receiving seat 203 approaches or moves away from the positioning component 40. The positioning component 40 can be used to support the second workpiece 0B. Specifically, when it approaches the second workpiece 0B along the first direction, it moves a first distance to reach the second position. The second position is closer to the positioning component 40 relative to the first position. Then, it moves a second distance in the opposite direction along the first direction to move away from the second workpiece 0B and returns to the first position. In this embodiment, the first direction and the second direction are parallel. It can be understood that the first direction is not limited to this, as long as it can approach or move away from the second workpiece 0B. When the receiving seat 203 approaches the second workpiece 0B, the second driving component 202 can push the first workpiece 0A on the receiving seat 203 in the second position to continue moving along the first direction to approach and assemble it to the second workpiece 0B. After assembly, the receiving seat 203 can move in the opposite direction along the first direction to move away from the position of the second workpiece 0B. Figure 16 As shown, the feeding assembly 20 includes a slider 207 and a slide rail 206. The assembly mechanism also includes a mounting base 50. The slide rail 206 and the first driving component 201 are both mounted on the mounting base 50. The first driving component 201 can drive the slider 207 to move relative to the slide rail 206 in a first direction. In this embodiment, the receiving seat 203 and the slider 207 are separately arranged and mounted on the slider 207. Of course, the receiving seat 203 and the slider 207 can also be integrated.

[0088] As can be seen, in this embodiment, when the assembly mechanism assembles the first workpiece 0A and the second workpiece 0B in the pusher assembly 20, it does not directly push the first workpiece 0A to the second workpiece 0B. Instead, it first pushes the receiving seat 203 containing the first workpiece 0A, so that the receiving seat 203 carrying the first workpiece 0A approaches the second workpiece 0B. In this way, the stroke of the first workpiece 0A moving towards the second workpiece 0B is divided into two stages. In the first stroke stage, the receiving seat 203 carries the first workpiece 0A a first distance to approach the second workpiece 0B. In the second stroke stage, the receiving seat 203 no longer moves, but the second drive component 202 pushes the first workpiece 0A a second distance to approach and until it is assembled into the second workpiece 0B. Since the second distance is set to be less than the first distance, the stroke of the first workpiece 0A being directly pushed during the entire movement stroke will be shortened, thereby improving the problem of the first workpiece 0A's posture change affecting assembly due to excessive stroke during the direct pushing process.

[0089] This process can be continued. Figures 18 to 21 understand, Figure 18 for Figure 17A schematic diagram of the positioning component 40's locking base 404 and receiving base 203 being close to each other at a certain distance; Figure 19 for Figure 16 Enlarged schematic diagram of section H in the middle; Figure 20 for Figure 18 A schematic diagram showing the structure in which the middle clamping base 404 and the receiving base 203 are brought closer together; Figure 21 for Figure 20 Enlarged schematic diagram of part I in the middle.

[0090] like Figure 19 , 21 As shown, the receiving seat 203 is provided with a pusher groove 203b. The pusher groove 203b is a through groove, that is, it extends through the receiving seat 203 along the length direction of the pusher groove 203b, which is also the first direction. When the first workpiece 0A is located in the pusher groove 203, the opening 0Aa of the first workpiece 0A faces the length direction parallel to the pusher groove 203b. At this time, the width of the pusher groove 203b perpendicular to the first direction is approximately equal to the width of the first workpiece 0A. Specifically, the width of the pusher groove 203b is slightly larger than the width of the storage position 2032, that is, slightly larger than the width of the first workpiece 0A. In this way, the side walls of the pusher groove 203 on both sides and the first workpiece 0A have a very small gap to limit the offset direction of the first workpiece 0A when it is pushed. The bottom of the pusher trough 203 can be set with a storage position 2032 for the first workpiece 0A. The storage position 2032 can be provided with a first adsorption hole (not shown in the figure). After the first workpiece 0A is lowered to the storage position 2032 by the gripping structure 303, the first adsorption hole can adsorb the first workpiece 0A and make it stably located in the storage position 2032, which is the same as the purpose of setting the second adsorption hole.

[0091] The pusher assembly 20 may further include a pusher rod 204, and the moving end of the second drive component 202 may be connected to the pusher rod 204. When the second drive component 202 is a cylinder, its moving end is the cylinder rod, which may also be connected to the pusher rod 204. The pusher rod 204 is embedded in the pusher groove 203b, thereby guiding the movement of the pusher rod 204. The pusher rod 204 directly pushes the first workpiece 0A. Setting the pusher rod 204 allows for easy design of its length according to requirements. The moving end of the second drive component 202 may not need adjustment; of course, the moving end can also directly push the first workpiece 0A. Figure 19 , 21 In the middle, the pusher chute 203b is gradually widened at the end away from the second drive component 202.

[0092] In detail, such as Figure 22 , 23 As shown, Figure 22 for Figure 19 Enlarged schematic diagram of position 203b in the middle pusher chute; Figure 23 for Figure 19Enlarged schematic diagram of the location of the 4041a card slot.

[0093] The pusher groove 203b includes a first groove segment 203b1 and a second groove segment 203b2, which are connected to the first groove segment 203b1 along a first direction. The first groove segment 203b1 includes two opposing first groove sidewalls 203b11, which are parallel to each other. The second groove segment 203b2 includes two opposing second groove sidewalls 203b21, which are gradually widened in a direction away from the first groove segment 203b1. That is, this end of the pusher groove 203b is a Y-shaped port, which facilitates the smooth push of the pusher rod 204 and prevents jamming. At this time, the storage position 2032 for storing the first workpiece 0A is located inside the first groove segment 203b1. There are small gaps between the first groove sidewalls 203b11 of the first groove segment 203b1 and the side of the first workpiece 0A, so as to achieve the purpose of limiting the movement of the first workpiece 0A along the first direction.

[0094] The push rod 204 is used to push the rod end 2041 of the first workpiece 0A. It is adapted to contact the first workpiece 0A. The rod end 2041 of the push rod 204 is adapted to the first workpiece 0A, such as... Figure 19 , 21 In 22 and 23, the outer surface of the first workpiece 0A is an arc surface, and the end 2041 of the push rod 204 is also an arc surface. Moreover, the arc surface opening faces the storage position 2032 of the first workpiece 0A, thereby reliably pushing the snap ring that serves as the first workpiece 0A. The two ends of the arc surface have a certain limiting effect on the first workpiece 0A, so that the posture remains stable when it is finally pushed to the second workpiece 0B.

[0095] In some embodiments, such as Figure 19 As shown, the receiving base 203 has a first end 2031, through which the Y-shaped port of the aforementioned push groove 203b passes. The first end 2031 is the end that is away from the second driving component 202 in the first direction. The first end 2031 of the receiving base 203 has a slot 203a. The opening of the slot 203a faces parallel to the first direction, i.e., the slot 203a faces the positioned second workpiece 0B. The slot 203a is a through slot that vertically penetrates the receiving base 203. Furthermore, the corresponding groove wall 203a2 of the slot 203a is adapted to a portion of the outer peripheral wall of the second workpiece 0B. Specifically, the corresponding groove wall 203a2 of the slot 203a can be an arc-shaped wall. In this embodiment, the second workpiece 0B is a shaft component. The retaining ring, which serves as the first workpiece 0A, needs to be engaged with the cylindrical rod 0B2 of the shaft component. Correspondingly, the retaining groove 203a is an arc-shaped groove. Thus, under the action of the first driving component 201, the receiving seat 203 can be pushed to engage with the retaining groove 203a and the rod 0B2 of the second workpiece 0B. Figure 15As shown, when the receiving seat 203 moves to the left, its slot 203a will engage with the rod OB2 ( Figure 15 (The rod portion 0B2 in the middle is not shown). In this way, the relative positions of the second workpiece 0B and the receiving seat 203 are fixed. The process of the receiving seat 203 moving to this position is the first stroke stage of the first workpiece 0A, which is equivalent to further determining the relative positions of the first workpiece 0A and the second workpiece 0B. Then, the second driving component 202 drives the first workpiece 0A to continue moving towards the second workpiece 0B and finally engages with the rod portion 0B2 of the second workpiece 0B. This process is the second stroke stage of the first workpiece 0A. It can be seen that setting the slot 203a for pre-positioning the second workpiece 0B can better ensure the accuracy of the assembly of the first workpiece 0A and the second workpiece 0B.

[0096] It is understood that the groove wall of the slot 203a can match the outer peripheral wall of the second workpiece 0B, and it does not have to be curved. For example, when the part assembled with the second workpiece 0B and the first workpiece 0A is square, the shape of the slot 203a can also be square, which will not be elaborated further.

[0097] In this embodiment, the pushing assembly 20 also includes a pressure plate 205. The pressure plate 205 and the receiving seat 203 are separately arranged and are clamped onto the pushing groove 203b. This limits the pushing rod 204, preventing the long pushing rod 204 from warping and ensuring reliable pushing of the first workpiece 0A. The part of the pushing groove 203b near the first end 2031 exposes the pressure plate 205. That is, the pressure plate 205 only clamps a part of the pushing groove 203b, and the end near the first end 2031 is not clamped, so that the material unloading assembly 30 can unload the material into the storage position 2032 of the pushing groove 203b. This also facilitates the observation of the posture of the first workpiece 0A after placement. This observation can be done manually or automatically by means of an infrared sensor 104, etc. Figure 13 As shown, the infrared sensor 104 can be installed on the storage base 1032, located on one side of the storage structure 1031. Multiple infrared sensors 104 can be set in the height direction of the storage structure 1031 to monitor the posture and the number of first workpieces 0A stacked at the same time.

[0098] In addition, multiple weight-reducing positioning holes 301b are respectively provided on both sides of the cutting seat 301 extending along the second direction. The weight-reducing positioning hole 301b includes two sections extending along the height direction. One section is the weight-reducing hole section 301b1, which has a notch structure, that is, the weight-reducing hole section 301b1 has an opening on one side perpendicular to the second direction, which can reduce weight as much as possible. The other section of the weight-reducing positioning hole 301b is the positioning hole section 301b2, which can fix the cutting seat 301 to the base of the material taking component 30 by fasteners.

[0099] Furthermore, as mentioned above, the first workpiece 0A is pushed through two stroke stages in this embodiment, thus shortening the stroke of the first workpiece 0A being directly pushed. In this embodiment, the storage position 2032 of the first workpiece 0A in the pusher groove 203b can be set closer to the second workpiece 0B. For example, the distance between the center of the storage position 2032 of the first workpiece 0A (the center of the retaining spring in this embodiment) and the edge 2033 of the pusher groove 203b along the first direction (i.e., the edge closer to the second workpiece 0B, specifically the opening edge of the first groove segment 203b1) is defined as the third distance. The third distance is less than or equal to 3.5 times the length of the storage position 2032 along the first direction and greater than or equal to 1.5 times the length of the storage position 2032 along the first direction. The length of the storage position 2032 along the first direction is the length of the first workpiece 0A along the first direction. The shape of the storage position 2032 is adapted to the shape of the first workpiece 0A. In this way, the first workpiece 0A can be as close as possible to the second workpiece 0B, and the distance between them can be shortened as much as possible to reduce the posture changes of the first workpiece 0A during the direct pushing process. Of course, the third distance cannot be too small, and it is necessary to ensure that the first workpiece 0A is not easy to fall off when the material picking component 30 places the first workpiece 0A in the pusher groove 203a.

[0100] As mentioned above, a pick-up component 30 is set between the pusher component 20 and the feeder component 10. It can be seen that the pick-up component 30 is not required; for example, the first workpiece 0A conveyed by the feeder component 10 can be directly conveyed to the pusher component 20. If the feeder component 10 directly feeds to the pusher component 20, feeding or pushing only one workpiece may result in insufficient accuracy. By setting the pick-up component 30, only one workpiece can be picked up at a time, which is beneficial for installation accuracy.

[0101] Next, let's look at the positioning component 40 that positions the second workpiece 0B.

[0102] In this embodiment, the positioning component 40 includes a locking base 404, which can be combined with... Figure 14 , 15As understood in 18, 19, 22, and 23, the locking base 404 has a locking hole 4041a, which penetrates the locking base 404 vertically, that is, the locking hole 4041a penetrates the locking base 404 in the thickness direction. The locking hole 4041a has an opening in the first direction, and its opening is opposite to the groove 203a1 of the locking groove 203a. The hole wall corresponding to the locking hole 4041a is adapted to a part of the outer peripheral wall of the second workpiece 0B. Specifically, in this embodiment, the hole wall corresponding to the locking hole 4041a is an arc-shaped wall. After the second workpiece 0B is positioned, the rod portion 0B2 of the second workpiece 0B is engaged in the locking hole 4041a. When the second workpiece 0B is a shaft member with a cylindrical rod portion 0B2, the locking hole 4041a is also set as an arc-shaped hole. The locking groove 203a and the locking hole 4041a are, for example, enclosed in a complete circle or enclosed in a nearly closed annulus. Figure 21 As shown, the slot 203a of the receiving seat 203 and the slot 4041a of the positioning base 404 can more reliably position the rod 0B2 of the second workpiece 0B in the radial direction of the second workpiece 0B, thereby further ensuring that the second workpiece 0B can be maintained in a predetermined posture for assembly with the first workpiece 0A.

[0103] In detail, the clamping base 404 includes a base body 4042 and a clamping plate 4041 fixed to the base body 4042. A clamping hole 4041a is provided at the end of the clamping plate 4041, specifically penetrating vertically through the clamping plate 4041, which is also the thickness direction of the clamping plate 4041. With this configuration, the clamping plate 4041 can protrude from the base body 4042 towards the receiving seat 203, facilitating the engagement of the clamping hole 4041a and the second workpiece 0B. The base body 4042 ensures sufficient strength, and the clamping plate 4041 can be relatively thin, just enough to clamp the second workpiece 0B. Additionally, as... Figure 16 As shown, the base body 4042 of the card base 404 and the slider 207 of the pusher assembly 20 are also mounted on the mounting base 50 of the assembly mechanism.

[0104] like Figure 24 As shown, Figure 24 for Figure 15 A schematic diagram of the structure after the second workpiece 0B presses against the support component 403.

[0105] It can be seen that the aforementioned card plate 4041 and the push groove 203b of the receiving seat 203 are vertically staggered, that is, the bottom of the card hole 4041a in the vertical direction is not lower than the top of the push groove 203b in the vertical direction. When the first workpiece 0A moves towards the second workpiece 0B in the first direction, it will not be blocked by the card plate 4041, so as not to interfere with the pushing of the first workpiece 0A in the first direction.

[0106] The positioning component 40 in this embodiment further includes a sixth driving component 405, which drives the positioning base 404 to move along a first direction to move closer to or further away from the second workpiece 0B. The sixth driving component 405 can also be mounted on the mounting base 50. That is, the positioning base 404 can also move along the first direction to adjust the distance between the second workpiece 0B and the second workpiece 0B.

[0107] In this embodiment, the positioning component 40 further includes a positioning seat 402, which is used to place the second workpiece OB, such as Figure 3 , 14 As shown, the positioning assembly 40 includes a vertically extending mounting bracket 407, a positioning seat 402 disposed on the mounting bracket 407, and the positioning assembly 40 also includes a support member 403, a pressing member 406, and a seventh driving member 401. The seventh driving member 401 is used to drive the pressing member 406 to move closer to or away from the support member 403. The second workpiece 0B can be positioned in the height direction between the support member 403 and the pressing member 406, and radially engaged by the aforementioned slot 203a and slot hole 4041a, thus the position and orientation of the second workpiece 0B can be reliably positioned.

[0108] like Figures 16 to 21 As shown, the support component 403 includes a support base 4031 and a support rod 4032 supported on the support base 4031. The rod portion OB2 of the second workpiece OB can be supported on the support rod 4032. The support rod 4032 has an elastic component (not shown in the figure) below it. When the seventh driving component 401 drives the pressing component 406 to move downward a certain distance (compared to...), Figure 3 , 14 (Understanding) After the second workpiece 0B on the positioning seat 402 is pressed down, the pressing component 406 and the positioning seat 402 move down together until the rod 0B2 of the second workpiece 0B abuts against the support rod 4032. At this time, the support rod 4032 compresses the elastic component, so that the second workpiece 0B is reliably limited between the pressing component 406 and the support component 403. Moreover, when the first workpiece 0A is assembled, the seventh driving component 401 drives the pressing component 406 to move up. Under the reset action of the elastic component, the second workpiece 0B, which is assembled with the first workpiece 0A, can be disengaged from the locking base 404, which facilitates the next step of assembly and unloading.

[0109] This embodiment provides an assembly method, including:

[0110] Step 1: Loading assembly 10 loads the first workpiece 0A;

[0111] Specifically, after passing through the ring track 101 and the straight track 102 of the vibratory feeder, the snap ring of the first workpiece 0A is conveyed downward with the opening 0Aa having the same horizontal orientation, and is stacked on the storage structure 1031 along the height direction, that is, stacked on the storage structure 1031 along the fourth direction.

[0112] Step 2: The material handling component 30 picks up the material and places the first workpiece 0A onto the material pushing component 20;

[0113] Specifically, the material is picked up by the reciprocating movement of the cutting seat 301 along the second direction. Each time, a first workpiece 0A is picked up. Then, the gripping structure 303 grips the first workpiece 0A on the cutting seat 301 and places it in the push groove 203b of the receiving seat 203 of the pusher assembly 20. That is, the gripping structure 303 reciprocates along the third direction to grip the first workpiece 0A.
