Description

Technical fields:

[0001] This invention belongs to the technical field of automotive clip installation equipment, and specifically relates to an automatic clip assembly device. Background technology:

[0002] Automotive clips are connectors used to install certain automotive parts. They are typically made of plastic and are attached to the corresponding automotive components to connect the components to the car body. This is one of the main connection methods for some automotive parts today.

[0003] To improve assembly efficiency, robotic arms are now used to assemble the clips. Referring to the existing publication "An Automatic Assembly Device for Automobile Clips" with the publication number "CN108500584A", the robotic arms are used to automatically install the clips, which can greatly improve the efficiency and quality of clip assembly.

[0004] However, many automated assembly equipment can only assemble parts of the same size, which results in poor application of current assembly equipment. Especially for some small parts, different sizes of parts of the same shape still need to be assembled with different equipment, which directly increases production costs and also increases the waste of resources and production space. Therefore, a snap-fit ​​automatic assembly device is established. Summary of the Invention:

[0005] The purpose of this invention is to provide an automatic snap-fit ​​assembly device to solve the above-mentioned problems. The device uses a movable side plate and a follower block and spring connected to it to drive the movable side plate to move back and forth along the moving groove, thereby clamping and positioning parts of the same shape but different sizes, and realizing the function of processing different parts with one machine.

[0006] To address the aforementioned problems, this invention provides a technical solution for an automatic snap-fit ​​assembly device: It includes a processing table, with fixed seats detachably and uniformly connected to the top sidewall of the processing table. Two rows of fixed seats are arranged, and a placement plate is provided above each fixed seat. A fixed side plate is fixedly connected to the top sidewall of the placement plate at one end edge.

A movable side plate is fixedly connected to the top sidewall of each follower block. Two springs are fixedly connected to the opposite sidewall of each follower block and the fixed side plate. The springs are fixedly connected to the sidewall of one end of the movable slot via their ends away from the follower block. The top edges of the opposite sidewalls of the fixed and movable side plates have downward inclined structures, and anti-slip pads are embedded in the opposite sidewalls of the fixed and movable side plates.

[0007] Preferably, a rotating groove is provided in the middle of the side wall opposite to the placement plate of the fixing seat, and a rotating column is rotatably connected in the rotating groove. The rotating column is detachably connected to the middle of the bottom side wall of the placement plate through its top end. Four auxiliary support columns are evenly fixedly connected to the top of the fixing seat and the side wall near the rotating groove. A rotating ball is rotatably connected to the middle of the top side wall of the auxiliary support column, and the rotating ball is in a fit-fitting structure with the bottom side wall of the placement plate.

[0008] Preferably, a vertical plate is detachably connected to the side wall of the processing table on the top of the table and on one side of the fixed seat. The number of vertical plates corresponds to the number of fixed seats. A rotating shaft is rotatably connected to the top of each vertical plate. A linkage rod is detachably connected between every two rotating shafts. A brushless motor is connected to the top of one of the vertical plates. A driven rod is detachably connected to the top side wall of both the rotating shaft and the brushless motor. The driven rod has a semi-circular structure. A clamping plate is fixedly connected to the end of the driven rod away from the rotating shaft. The clamping plate corresponds to the middle position of the placement plate. A rubber pad is fixedly connected to the opposite side wall of the clamping plate and the placement plate.

[0009] Preferably, a column is fixedly connected to each of the four corners of the top of the processing table. A top plate is fixedly connected to the end of each column away from the processing table. Horizontal guide rails are detachably connected to the top plate near both sides of the processing table. A first slider is slidably connected to the two horizontal guide rails. A vertical guide rail is provided below the first slider, and its two ends are detachably connected to the bottom sidewall of the first slider. A second slider is slidably connected to the vertical guide rail. A main telescopic rod is detachably connected to the middle of the bottom sidewall of the second slider. An assembly box is detachably connected to the output end of the main telescopic rod. The assembly box has an L-shaped structure and a storage trough inside. An opening communicating with the storage trough is provided through the top sidewall of the assembly box. A push telescopic rod is detachably connected to the sidewall near the bottom edge of the assembly box. The output end of the push telescopic rod extends into the processing table and is fixedly connected to a push... The assembly box has a push plate located below the bottom opening of the storage tank. A sealing plate is fixedly connected to the top side wall of the push plate. A pushing groove is opened at one end of the assembly box. A top support telescopic rod is detachably connected to the top side wall of the pushing groove. A pressing column is fixedly connected to the output end of the top support telescopic rod. The pressing column is a hollow cylindrical structure. A movable groove is opened in the side wall of the pressing column. A retractable column is inserted into the movable groove. The retractable column is also a hollow cylindrical structure. A material discharge port is opened through the bottom side wall of the assembly box opposite to the retractable column. The upper edge of the material discharge port is set with an inclined structure. Four infrared locators are evenly embedded in the bottom side wall of the assembly box near the edge of the material discharge port. An inner groove is opened in the side wall of the storage tank near the push plate. The sealing plate is telescopically inserted into the inner groove. One end of the sealing plate is a sloping structure. A ball bearing is rotatably connected to the bottom side wall of the push plate. The ball bearing contacts the bottom side wall of the main telescopic rod.

[0010] Preferably, a conveyor belt is provided on one side of the processing table, and the top sidewall of the conveyor belt is at the same level as the top sidewall of the processing table.

[0011] The beneficial effects of this invention are as follows: The parts that need to be fitted with clips are pressed forcefully between the fixed side plate and the movable side plate. The pushing force generated by pressing pushes the movable side plate outward along the moving groove until the parts are completely placed on the placement plate. The drive of four springs can pull the follower block to move in the moving groove, thereby driving the movable side plate to move synchronously and realize the clamping of the parts. Moreover, the drive of the springs can adaptively adjust to parts of different sizes, realizing the function of processing parts of different sizes with one device, reducing the number of different devices, reducing production costs and the processing space occupied by redundant devices.

[0012] By using a brushless motor to drive the driven rod to rotate, and through the transmission of the linkage rod, one brushless motor can drive multiple driven rods to rotate synchronously for adjustment. The rotation of the driven rods can drive the clamping plate to move synchronously, thereby achieving the pressing and clamping of parts, ensuring the stability of the parts, and avoiding any impact on the processing.

[0022] Example 1,

[0023] The specific implementation method adopts the following technical solution: such as Figure 1 , 5As shown in Figure 6, an automatic buckle assembly device of this embodiment includes a processing table 1. The top sidewall of the processing table 1 is detachably connected with fixed seats 8. Two rows of fixed seats 8 are provided. Each fixed seat 8 has a placement plate 30 above it. The top sidewall of the placement plate 30 and one edge of it are fixedly connected with a fixed side plate 31. The top sidewall of the placement plate 30 has two moving grooves 33. Each moving groove 33 is slidably connected with a follower block 34. The top sidewall of the follower block 34 is fixedly connected with a movable side plate 32. Each follower block 34 and the sidewall opposite to the fixed side plate 31 are fixedly connected with two springs 35. The springs 35 are fixedly connected to one sidewall of the moving groove 33 through the end away from the follower block 34. The top edges of the opposite sidewalls of the fixed side plate 31 and the movable side plate 32 are provided with downward inclined structures. The opposite sidewalls of the fixed side plate 31 and the movable side plate 32 are inlaid with anti-slip pads.

[0024] The technical principle and effect of this solution are as follows: Because the movable side plate 32 is set up to move back and forth along the moving groove 33 by the spring 35 and the follower block 34, and the top inner edges of the fixed side plate 31 and the movable side plate 32 are set up with an inclined structure, when it is necessary to install a component, the component is placed on the fixed side plate 31 and the movable side plate 32, and then the component is pressed down. Under the drive of the downward pressure, the movable side plate 32 can be pushed to move and expand along the moving groove 33. With continuous pressing, the component can be pressed into the placement plate 30, and then the spring 35... The contraction force pulls the follower block 34, causing it to move along the moving groove 33 with the movable side plate 32, forming a clamping of the parts. Thanks to the characteristics of the spring 35, the movable side plate 32 can move automatically, realizing the function of adaptive clamping of different parts. The tilt of the top of the fixed side plate 31 and the movable side plate 32 can improve the smoothness of pressing and placing the parts. In addition, in order to ensure the reliability of clamping the parts, anti-slip pads are embedded in the inner walls of the fixed side plate 31 and the movable side plate 32 to increase the friction between them and the parts, thereby ensuring the stability of the parts placement.

[0025] Example 2

[0026] The specific implementation method adopts the following technical solution: such as Figure 5-7 As shown, a rotating groove 39 is provided in the middle of the side wall opposite to the placement plate 30 of the fixing base 8. A rotating column 36 is rotatably connected in the rotating groove 39. The rotating column 36 is detachably connected to the middle of the bottom side wall of the placement plate 30 through its top end. Four auxiliary support columns 37 are evenly fixedly connected to the top of the fixing base 8 and the side wall near the rotating groove 39. A rotating ball 38 is rotatably connected to the middle of the top side wall of the auxiliary support column 37. The rotating ball 38 is fitted with the bottom side wall of the placement plate 30.

[0027] The technical principle and effect of this solution are as follows: Since some parts have a certain curvature, they can be installed on the placement plate 30 for processing when the curvature is not too large. In order to ensure the function of clamping and positioning the parts with curvature, a rotating column 36 is rotatably connected in the rotating groove 39 at the top of the fixed seat 8. The top of the rotating column 36 is detachably connected to the middle of the bottom side wall of the placement plate 30. In this way, the placement plate 30 can be rotated through the rotating column 36. After adjusting the placement plate 30 to the corresponding angle, the parts can be installed on the placement plate 30 according to the principle described in the processing table 1 of the embodiment for snap-fit ​​assembly.

[0028] In addition, to ensure the stability of the placement plate 30 itself, four auxiliary support columns 37 are set around the rotating column 36, and a rotating ball 38 is rotatably connected to the top center of each auxiliary support column 37. Since the rotating ball 38 is in contact with the bottom side wall of the placement plate 30, the auxiliary support columns 37 can provide stable support for the placement plate 30 through the rotating ball 38, ensuring the smooth rotation of the placement plate 30 and avoiding the instability of the placement plate 30 from affecting the assembly of the component clips.

[0029] Example 3

[0030] The specific implementation method adopts the following technical solution: such as Figure 1 and 5 As shown, a vertical plate 10 is detachably connected to the side wall of the processing table 1 on the top and one side of the fixed base 8. The number of vertical plates 10 corresponds to the fixed base 8. A rotating shaft 9 is rotatably connected to the top of each vertical plate 10. A linkage rod 12 is detachably connected between every two rotating shafts 9. A brushless motor 28 is connected to the top of one of the vertical plates 10. A driven rod 11 is detachably connected to the top side wall of both the rotating shaft 9 and the brushless motor 28. The driven rod 11 has a semi-circular structure. A clamping plate 29 is fixedly connected to the end of the driven rod 11 away from the rotating shaft 9. The clamping plate 29 corresponds to the middle position of the placement plate 30. Rubber pads are fixedly connected to the opposite side walls of the clamping plate 29 and the placement plate 30.

[0031] The technical principle and effect of this solution are as follows: Since the buckle is snapped onto the parts, when the adapter rises after assembly, it will cause the buckle to pull slightly upward. In order to avoid the parts from shifting due to this upward pull and affecting subsequent assembly, a clamping plate 29 is set up to press the parts and prevent the parts from shifting due to the upward pull. Rubber pads are fixed on the side wall of the clamping plate 29 to avoid wear on the parts and increase the stability of clamping.

[0032] To save energy consumption, multiple rotating shafts 9 are connected by linkage rods 12. Then, the brushless motor 28 is installed on the top side wall of the outermost vertical plate 10. The brushless motor 28 is connected to the corresponding driven rods 11 and linkage rods 12. When the brushless motor 28 is started, all the driven rods 11 can be driven to rotate along the rotating shaft 9 through the linkage rods 12, thereby driving the clamping plate 29 to move. Because the driven rods 11 have a semi-circular structure, the clamping plate 29 can be accurately moved onto the placement plate 30 to achieve pressing and positioning of the parts.

[0033] Example 4

[0034] The specific implementation method adopts the following technical solution: such as Figure 1-3 As shown, a column 2 is fixedly connected to each of the four corners of the top of the processing table 1. A top plate 3 is fixedly connected to the end of the column 2 away from the processing table 1. Horizontal guide rails 14 are detachably connected to the top plate 3 opposite to the processing table 1 and near both side edges. A first slider 15 is slidably connected to the two horizontal guide rails 14. A vertical guide rail 16 is set below the first slider 15. The vertical guide rail 16 is detachably connected to the bottom side wall of the first slider 15 through its two ends. A second slider 17 is slidably connected to the vertical guide rail 16. A main telescopic rod 4 is detachably connected to the middle of the bottom side wall of the second slider 17. An assembly box 5 is detachably connected to the output end of the main telescopic rod 4. The assembly box 5 has an L-shaped structure and a storage trough 6 is opened inside the assembly box 5. An opening communicating with the storage tank 6 is provided through the side wall of the assembly box 5. A push telescopic rod 7 is detachably connected to one side wall near the bottom edge. The output end of the push telescopic rod 7 extends into the processing table 1 and is fixedly connected to a push plate 18. The push plate 18 is located below the bottom opening of the storage tank 6. A sealing plate 19 is fixedly connected to the top side wall of the push plate 18. A pressing groove 21 is provided at one end of the assembly box 5. A top support telescopic rod 23 is detachably connected to the top side wall of the pressing groove 21. A pressing column 24 is fixedly connected to the output end of the top support telescopic rod 23. The pressing column 24 is a hollow cylindrical structure. A movable groove 25 is provided in the side wall of the pressing column 24. A retractable column 26 is telescopically inserted into the movable groove 25. The retractable column 26 is also a hollow cylindrical structure.

[0035] The technical principle and effect of this solution are as follows: the longitudinal guide rail 16 is slidably connected to the lower part of the transverse guide rail 14 by the first slider 15, and then the main telescopic rod 4 and the assembly box 5 are slidably connected to the lower part of the longitudinal guide rail 16 by the second slider 17. The cooperation between the transverse guide rail 14 and the longitudinal guide rail 16 enables the assembly box 5 to move in all directions. This function enables the assembly box 5 to move on the parts, thereby snapping the buckles into the corresponding positions of the parts.

[0036] The clips are fed into the storage tank 6 through the opening at the top of the assembly box 5. The clips are stacked in the storage tank 6. The pusher telescopic rod 7 connected to one side wall of the assembly box 5 drives the pusher plate 18 to move, which can push the clips falling from the storage tank 6. The moving space of the pusher plate 18 and the clips in the assembly box 5 is set to the size corresponding to the size of the clips to prevent the clips from tipping over during the movement. When the clips move to the position corresponding to the discharge port 20, the clips will fall into the discharge port 20. Then, the top support telescopic rod 23 is activated to drive the pressing column 24 and the retraction column 26 synchronously. As the device descends, the retracting column 26 contacts the buckle and is retracted into the movable groove 25. As the downward pressure continues, the buckle is pushed out from the discharge port 20 and falls into the corresponding position of the component. At this time, the top support telescopic rod 23 continues to descend, and as the retracting column 26 retracts, the top side wall of the pressing column 24 applies pressure to the buckle. As the pressure increases, the buckle is snapped into the corresponding position of the component, thus completing the buckle assembly. By repeating the above steps and moving the transverse guide rail 14 and the longitudinal guide rail 16, the buckle can be quickly assembled onto the component.

[0037] Example 5

[0038] The specific implementation method adopts the following technical solution: such as Figure 3-4 As shown, the bottom sidewall of the assembly box 5, opposite to the retracting column 26, is provided with a material discharge port 20. The upper edge of the material discharge port 20 is set with an inclined structure. Four infrared positioners 27 are evenly embedded in the bottom sidewall of the assembly box 5 near the edge of the material discharge port 20. The storage tank 6 is provided with an inner groove on the sidewall near the push plate 18. The sealing plate 19 is telescopically inserted into the inner groove. One end of the sealing plate 19 is a sloping structure. The bottom sidewall of the push plate 18 is rotatably connected with a ball bearing 22. The ball bearing 22 contacts the bottom sidewall of the main telescopic rod 4. A conveyor belt 13 is provided on one side of the processing table 1. The top sidewall of the conveyor belt 13 is at the same level as the top sidewall of the processing table 1.

[0039] The technical principle and effect of this solution are as follows: Since the clips are stacked in the storage tank 6, when the bottom clip is pushed away, the clips above will fall naturally. In order to prevent the falling clips from affecting the movement of the push plate 18, a push plate 18 is set up. When the push plate 18 moves, it will also bring out the sealing plate 19 at the same time. The end of the sealing plate 19 is set as an inclined structure. As the sealing plate 19 moves, it can push the clips above upwards. Finally, the sealing plate 19 will seal the bottom opening of the storage tank 6 to prevent the clips above from falling. Only when the push plate 18 retracts and pulls the sealing plate 19 back to the next clip can it fall down to wait for the next operation.

[0040] To ensure that the buckles are accurately assembled in the designated position, infrared positioners 27 are set up around the material drop port 20 for positioning, so as to avoid the buckles from being misaligned and affecting the assembly effect. The assembled parts can then be picked up and placed on the conveyor belt 13 for transport.

[0041] Specifically: In use, the parts are first placed on the placement plate 30 by pressing. The movable side plate 32 and rotating column 36 can stably clamp parts of different sizes or with a certain curvature, ensuring the stability of the parts placement. Then, the horizontal guide rail 14 and the vertical guide rail 16 are activated to drive the assembly box 5 to move in all directions. After the assembly box 5 moves to the designated position, the main telescopic rod 4 is activated to lower the assembly box 5 close to the parts. The infrared positioner 27 is used for auxiliary positioning to ensure that the material drop port 20 is aligned with the assembly position. The push telescopic rod 7 is used to move the buckle into the material drop port 20. Then, the top support telescopic rod 23 drives the pressing column 24 and the retraction column 26 to descend, pushing the buckle out of the assembly box 5 and assembling it on the parts. Repeating the above actions can quickly and accurately assemble the buckle on the parts. Finally, the assembled parts are placed on the conveyor belt 13 and sent away.
