Description

Technical Field

[0001] This application relates to the field of sealing ring assembly technology, specifically to an assembly device. Background Technology

[0002] Currently, when it is necessary to assemble sealing rings onto products, the assembly is usually done manually. However, manual assembly of sealing rings is inefficient and can easily cause the sealing rings to twist, resulting in a low yield rate. Utility Model Content

[0003] In view of the above, it is necessary to propose an assembly device to improve the efficiency and yield of assembling sealing rings.

[0004] This application provides an assembly device for assembling a sealing ring onto a product, including an elongation mechanism and a widening mechanism. The elongation mechanism carries the sealing ring and elongates it. The widening mechanism includes a moving component, a moving base, and a widening component. The moving component is located on one side of the elongation mechanism, and the moving base is located on the moving component and is used to move under the drive of the moving component. The widening component includes an opening and closing drive member and a first widening component and a second widening component that are pulsatorically connected to the opening and closing drive member. The opening and closing drive member is located on the moving base. The first widening component and the second widening component are spaced apart and are used to move closer to or further away from each other under the drive of the opening and closing drive member to widen the elongated sealing ring and assemble the widened sealing ring onto the product.

[0005] The assembly device of this application embodiment, by setting an elongation mechanism and a widening mechanism, when assembling the sealing ring onto the product, the elongation mechanism first carries the sealing ring and elongates it. Then, the moving component drives the moving seat and the widening component to move toward the elongation mechanism. The first widening component and the second widening component are inserted into the elongated sealing ring. The opening and closing drive component drives the first widening component and the second widening component to move away from each other, so that the first widening component and the second widening component widen the elongated sealing ring. Then, the moving component drives the moving seat and the widening component to move toward the product and make the sealing ring surround the outside of the product. The opening and closing drive component drives the first widening component and the second widening component to disengage from the sealing ring, so that the sealing ring is fitted onto the product. This realizes the function of automatically assembling the sealing ring, reduces the probability of the sealing ring being twisted when assembled onto the product, and improves the efficiency and yield of assembling the sealing ring.

The width of the limiting hole along the sliding direction of the sliding seat is greater than the width of the lifting member along the sliding direction of the sliding seat. The lifting drive is used to drive the sliding seat closer to the opening and closing drive through the lifting member.

[0011] In some embodiments, the widening mechanism further includes a stop member disposed on the movable seat and located on the side of one of the mounting seats opposite to the other mounting seat. The stop member is used to abut against the corresponding mounting seat when the two mounting seats move away from each other, so as to limit the distance between the two mounting seats.

[0012] In some embodiments, the elongation mechanism includes an elongation assembly, which includes a support frame, a lifting drive, an elongation drive, a first elongation member, and a second elongation member.

The first elongation member is drivenly connected to the elongation drive. The second elongation member is drivenly connected to the elongation drive and is disposed opposite to the first elongation member. The first elongation member and the second elongation member are used to pass through the through hole and insert into the sealing ring when the elongation drive approaches the bearing position, and are used to move away from each other under the drive of the elongation drive to elongate the sealing ring.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0030] Please see Figure 1 and Figure 9 This application provides an assembly device 100 for assembling a sealing ring 800 onto a product 900. The sealing ring 800 can be an O-ring, D-ring, square ring, or other elastic sealing element with a hollow center; the product 900 can be a lens, sound module, or other component of an electronic device. For ease of understanding, this application uses an O-ring as the sealing ring 800 and a mobile phone lens as the product 900 as an example for illustration; however, this is not intended to limit the scope of this application.

[0031] Please see Figure 1 , Figure 4 , Figure 5 and Figure 9 In this embodiment, the assembly device 100 includes a lengthening mechanism 10 and a widthening mechanism 20.

[0032] The elongation mechanism 10 is used to support the sealing ring 800 and elongate the sealing ring 800.

[0033] The widening mechanism 20 includes a moving component 21, a moving base 22, and a widening component 23. The moving component 21 is located on one side of the elongation mechanism 10, and the moving base 22 is located on the moving component 21. The moving base 22 is used to move under the drive of the moving component 21. The widening component 23 includes an opening and closing drive member 231 and a first widening member 234 and a second widening member 235 that are connected to the opening and closing drive member 231. The opening and closing drive member 231 is located on the moving base 22. The first widening member 234 and the second widening member 235 are spaced apart. The first widening member 234 and the second widening member 235 are used to move closer to each other or further away from each other under the drive of the opening and closing drive member 231 to widen the elongated sealing ring 800 and assemble the widened sealing ring 800 onto the product 900.

[0034] When the assembly device 100 assembles the sealing ring 800 onto the product 900, the elongation mechanism 10 first supports the sealing ring 800 and elongates it. Then, the moving component 21 drives the moving seat 22 and the widening component 23 to move toward the elongation mechanism 10. The first widening component 234 and the second widening component 235 are inserted into the elongated sealing ring 800. The opening and closing drive component 231 drives the first widening component 234 and the second widening component 235 to move away from each other, so that the first widening component 234 and the second widening component 235 elongate the sealing ring. The sealing ring 800 is widened, and then the moving component 21 drives the moving seat 22 and the widening component 23 to move toward the product 900 and make the sealing ring 800 surround the outside of the product 900. The opening and closing drive component 231 drives the first widening component 234 and the second widening component 235 to disengage from the sealing ring 800 so that the sealing ring 800 is fitted onto the product 900, thereby realizing the function of automatic assembly of the sealing ring 800, reducing the probability of the sealing ring 800 being twisted when assembled onto the product 900, and improving the efficiency and yield of assembling the sealing ring 800.

[0035] In this embodiment, the moving component 21 can be a linear slide or part of a three-coordinate moving platform (not shown), thereby enabling the moving base 22 to move accurately. In other embodiments, the moving component 21 can also be a robotic arm, which is not specifically limited in this application.

[0036] Please see Figure 2 and Figure 3 The extension mechanism 10 includes an extension component 11, which includes a support frame 111, a lifting drive component 112, an extension drive component 113, a first extension component 116, and a second extension component 117. A support frame 111 is located on one side of the movable component 21. The support frame 111 has a bearing position 1111 for bearing the sealing ring 800. A through hole 1112 is provided at the bearing position 1111 of the support frame 111. A lifting drive 112 is located on the support frame 111 and below the bearing position 1111. An extension drive 113 is connected to the lifting drive 112 to move closer to or away from the bearing position 1111 under the drive of the lifting drive 112. A first extension member 116 is drivenly connected to the extension drive 113. A second extension member 117 is drivenly connected to the extension drive 113 and is positioned opposite to the first extension member 116. The first extension member 116 and the second extension member 117 are used to pass through the through hole 1112 and insert the sealing ring 800 when the extension drive 113 moves closer to the bearing position 1111, and to move away from each other under the drive of the extension drive 113 to extend the sealing ring 800. Among them, the lifting drive component 112 can be a telescopic cylinder, and the extension drive component 113 can be a finger-clamping cylinder.

[0037] When the elongation assembly 11 elongates the sealing ring 800, the lifting drive 112 drives the elongation drive 113 to move towards the bearing position 1111. The elongation drive 113 drives the first elongation member 116 and the second elongation member 117 to insert into the sealing ring 800. Then, the elongation drive 113 drives the first elongation member 116 and the second elongation member 117 to move away from each other, thus elongating the sealing ring 800. In this way, the elongation assembly 11 can automatically elongate the sealing ring 800, improving the efficiency of elongating the sealing ring 800.

[0038] In this embodiment, there are multiple first elongation members 116 and multiple second elongation members 117, each corresponding to the other. The elongation assembly 11 also includes a first connector 114 and a second connector 115, which are connected to the elongation drive 113. Multiple first elongation members 116 are spaced apart from the first connector 114, and multiple second elongation members 117 are spaced apart from the first connector 114. Each first elongation member 116 is directly opposite to its corresponding second elongation member 117. The elongation drive 113 drives the first connector 114 and the second connector 115 to move in opposite directions, causing each first elongation member 116 and its corresponding second connector 115 to move closer to or further away from each other. Thus, the elongation assembly 11 can simultaneously elongate multiple sealing rings 800, thereby further improving the efficiency of elongating the sealing rings 800.

[0039] In this embodiment, the extension mechanism 10 further includes a support component 12 and a linear module 13. The support component 12 includes a fixed frame 121, a moving drive component 122, and a support seat 123. The fixed frame 121 is located on one side of the support frame 111, the moving drive component 122 is located on the fixed frame 121, and the support seat 123 is connected to the moving drive component 122 to move up and down under the drive of the moving drive component 122. The support seat 123 has a support position 1231, which is used to support the material belt 700 carrying the sealing ring 800. The support seat 123 has a clearance opening 1232 at the support position 1231. The linear module 13 is connected to the support frame 111 and extends toward the fixed frame 121. The linear module 13 is used to drive the support frame 111 to move closer to or away from the fixed frame 121, and when the support frame 111 moves closer to the fixed frame 121, the through hole 1112 is aligned with the clearance opening 1232.

[0040] Specifically, the sealing rings 800 are spaced on the carrier belt 700, facilitating storage and transportation and preventing twisting and entanglement. A clearance opening (not shown) extending along the length of the carrier belt 700 is provided in the middle. The moving drive 122 can be a telescopic cylinder. When the extension mechanism 10 extends the sealing rings 800, the robot (not shown) first places the carrier belt 700 carrying the sealing rings 800 onto the support position 1231 of the support seat 123, directly opposite the clearance opening 1232. Then, the linear module 13 drives the extension assembly 11 to move towards the fixed frame 121, positioning the extension assembly 11 below the support seat 123. Afterward, the moving drive 122 drives the support seat 123 towards the support frame 111, with the first extension member 116 and the second extension member 117 passing through the through hole 111. 2. The clearance opening 1232 and the clearance opening extend into the sealing ring 800. The extension drive 113 drives the first extension member 116 and the second extension member 117 to move away from each other, extending the sealing ring 800 and separating it from the carrier belt 700. Then, the movement drive 122 drives the carrier seat 123 away from the support frame 111. The extended sealing ring 800 passes through the clearance opening to avoid interference with the carrier belt 700. The linear module 13 drives the extension assembly 11 to return to its original position so that the widening mechanism 20 can widen the sealing ring 800. In this way, by setting the carrier assembly 12 and the linear module 13, the widening mechanism 10 can easily remove the sealing ring 800 from the carrier belt 700 and extend the sealing ring 800.

[0041] In this embodiment, the extension mechanism 10 further includes a base 14, which has a slide rail 141. A fixing frame 121 is disposed on the base 14 and located at one end of the slide rail 141. A linear module 13 is disposed on the base 14 and located on one side of the slide rail 141. The extension direction of the linear module 13 is the same as the extension direction of the slide rail 141. A support frame 111 is slidably disposed on the slide rail 141 and connected to the linear module 13. The linear module 13 drives the support frame 111 to slide on the slide rail 141 so that the support frame 111 moves closer to or away from the fixing frame 121. This helps to improve the accuracy and smoothness of the linear module 13 driving the extension mechanism 10 to move closer to or away from the fixing frame 121.

[0042] Please refer to the following: Figure 5 and Figure 6 Both the first support member 234 and the second support member 235 have a limiting part 2342, which is used to limit the sealing ring 800. By providing the limiting part 2342 on the first support member 234 and the second support member 235 to limit the sealing ring 800, the probability of the sealing ring 800 being twisted due to movement on the first support member 234 and the second support member 235 can be effectively reduced, thereby effectively reducing the probability of the sealing ring 800 being twisted when assembled onto the product 900, and further improving the yield of the assembly device 100 in assembling the sealing ring 800.

[0043] In this embodiment, the limiting part 2342 is a limiting groove, which is formed on the side opposite to the first supporting member 234 and the second supporting member 235. When the first supporting member 234 and the second supporting member 235 expand the sealing ring 800, the sealing ring 800 abuts against the groove wall of the limiting groove. The limiting groove can fix the sealing ring 800 on a flatter plane, effectively preventing the uneven height of the sealing ring 800 on the first supporting member 234 and the second supporting member 235 caused by the tilt of the material carrier belt 700. This effectively reduces the probability of the sealing ring 800 tilting and twisting when it is fitted on the product 900.

[0044] In this embodiment, the first support member 234 and the second support member 235, both located away from the engagement and disengagement drive member 231, are provided with claws 2341 for opening the sealing ring 800. A limiting groove is formed on the claws 2341. The claws 2341 can reduce the contact area between the first support member 234 and the second support member 235 and the sealing ring 800, thereby facilitating the sealing ring 800 to disengage from the first support member 234 and the second support member 235.

[0045] In this embodiment, the surface of the gripper 2341 is polished, which reduces the friction between the gripper 2341 and the sealing ring 800, making it easier for the sealing ring 800 to disengage, and further reducing the probability of the sealing ring 800 being twisted or deformed.

[0046] Please refer to the following: Figure 7 In another embodiment, the limiting portion 2342 is the area formed between the side of the first support member 234 and the second support member 235 that are far apart from each other and the corresponding gripper 2341, and the limiting portion 2342 is provided with a notch 2343.

[0047] Specifically, the limiting part 2342 is an L-shaped stepped area formed between the side of the first widening member 234 and the second widening member 235 that is far apart from each other and the corresponding gripper 2341. When the first widening member 234 and the second widening member 235 open the sealing ring 800, the sealing ring 800 abuts against the limiting part 2342, and the limiting part 2342 can also fix the sealing ring 800 on a flatter plane, thereby effectively reducing the probability of the sealing ring 800 tilting and twisting when it is fitted onto the product 900. In addition, the notch 2343 divides the end of the gripper 2341 that is far away from the engagement drive member 231 into two parts, thereby reducing the contact area between the gripper 2341 and the sealing ring 800 when the sealing ring 800 is disengaged from the first widening member 234 and the second widening member 235, thus facilitating the disengagement of the sealing ring 800 from the first widening member 234 and the second widening member 235.

[0048] In another embodiment, both the first support member 234 and the second support member 235 are provided with adsorption holes 2344 extending to the limiting portion 2342. The adsorption holes 2344 can provide negative pressure gas to increase the stability of the contact between the sealing ring 800 and the limiting portion 2342, thereby helping to reduce the probability of the sealing ring 800 being twisted or deformed.

[0049] Please refer to the following: Figure 8 In another embodiment, when the limiting part 2342 is the area formed between the side of the first support member 234 and the second support member 235 that are far apart from each other and the corresponding gripper 2341, a limiting groove can also be opened at the position of the gripper 2341 near the limiting part 2342. Then the limiting part 2342 and the limiting groove cooperate to limit the sealing ring 800 twice, thereby further reducing the probability of the sealing ring 800 tilting and twisting when it is fitted on the product 900.

[0050] Please see Figure 5 and Figure 9 In this embodiment, the widening mechanism 20 further includes a first opening and closing unit 232 and a second opening and closing unit 233 disposed opposite to each other. Both the first opening and closing unit 232 and the second opening and closing unit 233 include a mounting base 2321, a sliding base 2322 and an elastic element 2323. Mounting base 2321 is connected to opening and closing drive member 231. Mounting base 2321 of the first opening and closing unit 232 and the second opening and closing unit 233 are used to move closer or further away from each other under the drive of opening and closing drive member 231. Sliding seat 2322 is slidably disposed on mounting base 2321 for lifting and lowering. First support member 234 and second support member 235 are respectively disposed on sliding seat 2322 of the first opening and closing unit 232 and sliding seat 2322 of the second opening and closing unit 233. Elastic member 2323 can be a tension spring. Both ends of elastic member 2323 are respectively connected to sliding seat 2322 and mounting base 2321. Elastic member 2323 is used to drive sliding seat 2322 to slide away from opening and closing drive member 231.

[0051] When the first support member 234 and the second support member 235 abut against the positioning mechanism (not shown) that carries the product 900, the sliding seat 2322 can drive the first support member 234 and the second support member 235 to float under the action of the elastic member 2323, thereby avoiding the first support member 234 and the second support member 235 from rigidly abutting against the positioning mechanism, and thus reducing the probability of damage to the first support member 234 and the second support member 235.

[0052] In this embodiment, there are multiple first support members 234 and multiple second support members 235, each corresponding to the other. Multiple first support members 234 are spaced apart on the sliding seat 2322 of the first opening and closing unit 232, and multiple second support members 235 are spaced apart on the sliding seat 2322 of the second opening and closing unit 233. Each first support member 234 is directly opposite to the corresponding second support member 235. The opening and closing drive member 231 drives multiple first support members 234 and multiple second support members 235 to simultaneously widen multiple sealing rings 800 for assembly through the first opening and closing unit 232 and the second opening and closing unit 233, thereby improving the efficiency of the assembly device 100 in assembling the sealing rings 800.

[0053] In this embodiment, the sliding seat 2322 has a limiting hole 2322a. The widening mechanism 20 also includes a lifting assembly 24, which includes a lifting drive 241 and a lifting member 242. The lifting drive 241 is disposed on the movable seat 22, and the lifting member 242 passes through the limiting hole 2322a and is connected to the lifting drive 241. The width of the limiting hole 2322a along the sliding direction of the sliding seat 2322 is greater than the width of the lifting member 242 along the sliding direction of the sliding seat 2322. The lifting drive 241 drives the sliding seat 2322 to move closer to the opening and closing drive 231 through the lifting member 242. The lifting drive 241 can be a telescopic cylinder.

[0054] By setting the lifting member 242 to pass through the limiting hole 2322a opened in the sliding seat 2322, the floating distance of the sliding seat 2322 can be limited, making the assembly of the first support member 234 and the second support member 235 of the sealing ring 800 more precise. By setting the lifting drive member 241 to drive the lifting member 242 to move, the lifting member 242 moves the sliding seat 2322 closer to the opening and closing drive member 231, so that when the sealing ring 800 is fitted on the product 900, the sliding seat 2322 can quickly pull the first support member 234 and the second support member 235 out of the sealing ring 800.

[0055] Please refer to the following: Figure 10In this embodiment, the movable seat 22 includes an upper seat body 221, a lower seat body 222, and a plurality of support rods 223. The upper seat body 221 and the lower seat body 222 are arranged vertically at intervals. The upper seat body 221 is connected to the movable component 21. The plurality of support rods 223 are arranged at intervals between the upper seat body 221 and the lower seat body 222, and the two ends of each support rod 223 are respectively connected to the upper seat body 221 and the lower seat body 222. The lower seat body 222 has a plurality of through holes 2221 arranged at intervals. The opening and closing drive member 231 is located on the side of the upper seat body 221 facing the lower seat body 222. The first opening and closing unit 232 and the second opening and closing unit 233 are both located between the upper seat body 221 and the lower seat body 222. Each set of first support members 234 and second support members 235 respectively passes through a through hole 2221. The inner wall of each through hole 2221 is provided with a plurality of actuating protrusions 2221a arranged at intervals.

[0056] After the first widening member 234 and the second widening member 235 widen the sealing ring 800, the moving component 21 drives the moving seat 22 and the widening component 23 to move towards the product 900, causing multiple products 900 to extend into their respective through holes 2221. Then, the lifting drive member 241 drives the lifting member 242 to move, causing the lifting member 242 to move the sliding seat 2322 closer to the opening and closing drive member 231. Multiple actuating protrusions 2221a in each through hole 2221 respectively stop the corresponding sealing ring 800. Multiple sets of the first widening member 234 and the second widening member 235 are then pulled out from their respective sealing rings 800, causing the sealing ring 800 to shrink and fit onto the corresponding product 900. This improves the accuracy of assembling the sealing ring 800 onto the product 900.

[0057] Please refer to it again. Figure 5 and Figure 9 In this embodiment, the widening mechanism 20 further includes a stop 25. The stop 25 is disposed on the movable seat 22 and located on the side of one mounting seat 2321 opposite to the other mounting seat 2321. The stop 25 can be a hydraulic damper. The stop 25 is used to abut against the corresponding mounting seat 2321 when the two mounting seats 2321 move away from each other, thereby limiting the distance between the two mounting seats 2321. This helps to improve the accuracy of the opening and closing drive 231 in driving the first widening member 234 and the second widening member 235 to widen the sealing ring 800, and reduces the probability of the first widening member 234 and the second widening member 235 damaging the sealing ring 800.

[0058] In this embodiment, the widening mechanism 20 includes a limiting component 26. The limiting component 26 includes a limiting drive member 261 and a limiting block 262. The limiting drive member 261 is disposed on the upper seat body 221 of the movable seat 22. The limiting drive member 261 can be a telescopic cylinder. The limiting block 262 is connected to the limiting drive member 261 and extends between the two mounting seats 2321. The limiting drive member 261 is used to drive the limiting block 262 to move between the two mounting seats 2321 when the two mounting seats 2321 approach each other, so as to limit the distance between the two mounting seats 2321 approaching each other, thereby improving the accuracy of the opening and closing drive member 231 driving the first widening member 234 and the second widening member 235 to approach each other.

[0059] Please refer to it again. Figure 1 The assembly device 100 also includes a first detection component 30, a second detection component 40, a third detection component 50, and a fourth detection component 60. Figure 1 The placement of the first detection element 30, second detection element 40, third detection element 50, and fourth detection element 60 is for illustrative purposes only and their positions can be set according to actual needs. The first detection element 30 is located on one side of the moving component 21 and is used to detect whether the sealing ring 800 of the incoming material is twisted. The second detection element 40 is located on one side of the moving component 21 and is used to detect whether the sealing ring 800, widened by the first widening component 234 and the second widening component 235, is evenly stretched or damaged. The third detection element 50 is located on one side of the moving component 21 and is used to detect whether the sealing ring 800 is assembled on the product 900. The fourth detection element 60 is located on one side of the moving component 21 and is used to detect whether the sealing ring 800 assembled on the product 900 is twisted.

[0060] Specifically, the first inspection component 30, the second inspection component 40, the third inspection component 50, and the fourth inspection component 60 can all be CCD cameras. These components use a vision system to inspect the sealing ring 800. The fourth inspection component 60 further uses line scanning to acquire the structure of the sealing ring 800 and determine whether it is twisted or deformed. The first and second inspection components 30 and 40 monitor the assembly process of the sealing ring 800, promptly marking defective or poorly opened sealing rings 800 to enhance control over the assembly process. The third and fourth inspection components 50 and 60 perform a final screening of the assembled product to prevent defective products from flowing to the next process. This improves the yield rate of assembling the sealing ring 800 onto the product 900.

[0061] In some other embodiments, the assembly device 100 may include only a portion of the first detection element 30, the second detection element 40, the third detection element 50, and the fourth detection element 60. This application does not specifically limit this aspect.

[0062] In summary, the assembly device 100 of this application embodiment, by providing an elongation mechanism 10 and a widening mechanism 20, when assembling the sealing ring 800 onto the product 900, the elongation mechanism 10 first supports the sealing ring 800 and elongates it. Then, the moving component 21 drives the moving seat 22 and the widening component 23 to move toward the elongation mechanism 10. The first widening member 234 and the second widening member 235 are inserted into the elongated sealing ring 800. The opening and closing drive component 231 drives the first widening member 234 and the second widening member 235 to move away from each other, so that the first widening member 234 and the second widening member 235 widen the elongated sealing ring 800. Then, the moving component 21 drives the moving seat 22 and the widening component 23 to move toward the product 900, so that the sealing ring 800 surrounds the outside of the product 900. The opening and closing drive component 231 drives the first support component 234 and the second support component 235 to disengage from the sealing ring 800, so that the sealing ring 800 is fitted onto the product 900, thereby realizing the function of automatic assembly of the sealing ring 800, reducing the probability of the sealing ring 800 being twisted when assembled onto the product 900, and improving the efficiency and yield of assembling the sealing ring 800. In addition, by setting the limiting part 2342 on the first support component 234 and the second support component 235 to limit the sealing ring 800, the probability of the sealing ring 800 being twisted due to movement on the first support component 234 and the second support component 235 can be effectively reduced, thereby effectively reducing the probability of the sealing ring 800 being twisted when assembled onto the product 900, and further improving the yield of the assembly device 100 in assembling the sealing ring 800.
