Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing technology, and in particular to a testing and assembly device and method for protective shells of new energy vehicles. Background Technology

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source. During the assembly process of new energy vehicles, each component needs to be tested first. For example... Figure 1 The protective shell for new energy vehicles shown includes a shell, a mounting bracket, and a spring hook. The mounting bracket is installed on the shell, and the spring hook is installed on the mounting bracket. The shell has through holes. Currently, during production, the outer dimensions and hole positions of the shell are first inspected by a testing device. After passing the inspection, the spring hook is then manually assembled onto the mounting bracket. However, since the spring hook and the mounting bracket are interference fit, manual assembly requires considerable force, resulting in low assembly efficiency. Summary of the Invention

[0003] Therefore, it is necessary to provide a testing and assembly device and method for protective shells of new energy vehicles that integrates testing and assembly functions to address the above problems.

[0004] A testing and assembly device for a protective shell of a new energy vehicle includes a support component, a testing component, and an assembly component. The support component includes a base plate, a fixed seat, and a support block. The fixed seat is mounted on the base plate, and the support block protrudes from the fixed seat, supporting the protective shell of the new energy vehicle. The testing component includes a first limiting block and two second limiting blocks. The first limiting block is used to insert a first through hole in the protective shell of the new energy vehicle, and the second limiting blocks are used to insert a second through hole in the protective shell of the new energy vehicle. The assembly component includes a mounting base, a push block, a support arm, a contour block, and a robotic arm. The mounting base is mounted on the base plate, the push block slides on the mounting base, the support arm is detachably mounted on the push block, and the contour block slides on the support arm, fixing a spring hook. The robotic arm is used to install the spring hook onto the contour block. During assembly, as the push block moves towards the mounting base of the protective shell of the new energy vehicle, one end of the contour block abuts against one end of the mounting base, and the push block pushes the spring hook from the contour block onto the mounting base.

[0005] In one embodiment, the cross-sectional dimension of the contour block is larger than the cross-sectional dimension of the card holder.

[0006] In one embodiment, the support component further includes a protruding edge protruding from the fixed base, the protruding edge being disposed along the periphery of the fixed base, and a groove being formed between the protruding edge and the support block; the detection component further includes a gauge, one end of which is a go gauge end and the other end of which is a stop gauge end, the go gauge end and the stop gauge end being selectively slidably disposed in the groove.

[0007] In one embodiment, the assembly component further includes a support and a pressure block, wherein there are multiple supports and pressure blocks, and they correspond one-to-one. The support is installed on the base plate, and each support is arranged along the periphery of the fixed seat. Each pressure block is used to press the periphery of the new energy vehicle protective shell.

[0008] In one embodiment, the assembly further includes a stand, a support rod, a linkage, and a handle. The stand is mounted on the support, one end of the support rod is pivotally connected to the stand, the pressure block is slidably disposed on the support rod, one end of the linkage is pivotally connected to the support rod, and the other end is pivotally connected to the handle. One end of the handle is pivotally connected to the stand. There are multiple supports, stands, support rods, linkages, and handles, and they correspond one-to-one.

[0009] In one embodiment, the contour block has a guide groove on one side, and the assembly assembly further includes a guide post, one end of which is mounted on the push block and the other end is slidably disposed in the guide groove; a limiting part is provided on one side of the contour block, and a snap-fit ​​part is provided on one side of the support arm, the snap-fit ​​part being used to abut against the limiting part.

[0010] In one embodiment, the support assembly further includes a support magnet mounted on the fixed base, and the support arm is magnetically attracted to the support magnet; the assembly assembly further includes an assembly magnet, and the assembly magnet is magnetically attracted to the support arm.

[0011] In one embodiment, the support assembly further includes a first fastener and a second fastener, both of which are mounted on the fixed base. One end of the first limiting block is inserted into the first fastener, and the other end passes through the first through hole. One end of the second limiting block is inserted into the second fastener, and the other end is inserted into the second through hole.

[0012] In one embodiment, the first limiting block includes a first pin portion, a first positioning portion, and a first gripping portion connected in sequence.

The second limiting block includes a second pin portion, a second positioning portion, and a second gripping portion connected in sequence. The second pin portion is used to insert the second fastener, and the second positioning portion is disposed corresponding to the second through hole.

[0013] A testing and assembly method for protective shells for new energy vehicles, based on the aforementioned testing and assembly device for protective shells for new energy vehicles, comprises the following steps: Hole position detection: Place the new energy vehicle protective shell on the support block, and insert the first limiting block and the second limiting block in sequence; if one end of the first limiting block can be inserted into the fixing seat and the other end can pass through the first through hole, and one end of the second limiting block can be inserted into the fixing seat and the other end can pass through the second through hole, then the positions of the first through hole and the second through hole are accurate, and the size of the first through hole and the size of the second through hole meet the requirements; otherwise, it is treated as a defective product; Spring hook assembly: After the support arm is placed on the fixed base, the robotic arm equipped with the spring hook quickly approaches the contour block, thereby installing the spring hook onto the contour block. Next, the support arm with the spring hook installed is inserted into the push block, and then the push block is pushed towards the holder. As the push block moves, one end of the contour block abuts against one end of the holder. Continuing to push the push block, the push block slides onto the contour block, thereby pushing the spring hook from the contour block to the holder, thus completing the installation of the spring hook.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a testing and assembly device for protective shells of new energy vehicles.

A robotic arm installs a spring hook onto a contour block. As the push block moves, one end of the contour block abuts against one end of the mounting base. The push block then pushes the spring hook from the contour block onto the mounting base, thereby completing the installation of the spring hook and improving assembly efficiency. The device integrates testing and assembly functions, eliminating the need for secondary positioning during assembly. Attached Figure Description

[0023] Please refer to Figures 1 to 5An embodiment of the invention provides a testing and assembly device 100 for a protective shell of a new energy vehicle, comprising a support assembly 10, a testing assembly 20, and an assembly assembly 30. The support assembly 10 includes a base plate 11, a fixing seat 12, and a support block 13. The fixing seat 12 is mounted on the base plate 11, and the support block 13 protrudes from the fixing seat 12, supporting the new energy vehicle protective shell 80. The testing assembly 20 includes a first limiting block 21 and two second limiting blocks 22. The first limiting block 21 is used to insert into a first through hole 811 of the new energy vehicle protective shell 80, and the second limiting blocks 22 are used to insert into the second through holes 812 of the new energy vehicle protective shell 80. The assembly component 30 includes a mounting base 31, a push block 32, a support arm 33, a contour block 34, and a robotic arm 35. The mounting base 31 is mounted on the base plate 11. The push block 32 is slidably mounted on the mounting base 31. The support arm 33 is detachably mounted on the push block 32. The contour block 34 is slidably mounted on the support arm 33. The contour block 34 is used to fix the spring hook 85. The robotic arm 35 is used to install the spring hook 85 onto the contour block 34. During assembly, as the push block 32 moves toward the mounting base 82 of the new energy vehicle protective shell 80, one end of the contour block 34 abuts against one end of the mounting base 82. The push block 32 then pushes the spring hook 85 from the contour block 34 onto the mounting base 82. In one embodiment, the protective shell 80 for new energy vehicles includes a shell 81, a mounting base 82, and a spring hook 85. The mounting base 82 is installed on the shell 81, and the spring hook 85 is installed on the mounting base 82. The shell 81 has a first through hole 811 and a second through hole 812. Optionally, there are two second through holes 812. The spring hook 85 is a metal part. The detection and assembly device 100 for the protective shell of new energy vehicles in this embodiment detects the accuracy of the first through hole 811 and the second through hole 812 by cooperating with the first limiting block 21 and the second limiting block 22. The spring hook 85 is installed on the contour block 34 by the robotic arm 35. As the push block 32 moves, one end of the contour block 34 abuts against one end of the mounting base 82. The push block 32 then pushes the spring hook 85 from the contour block 34 to the mounting base 82, thereby completing the installation of the spring hook 85 and improving the assembly efficiency. It integrates detection and assembly functions, and no secondary positioning is required during assembly.

[0024] like Figures 2 to 4As shown, in this embodiment, the support assembly 10 includes a base plate 11, a fixing seat 12, and a support block 13. The fixing seat 12 is mounted on the base plate 11, and the support block 13 protrudes from the fixing seat 12. The support block 13 is used to support the new energy vehicle protective shell 80. Optionally, the fixing seat 12 has two grooves 120. There are multiple support blocks 13, and each support block 13 is spaced apart along the periphery of the fixing seat 12. The periphery shape of the fixing seat 12 corresponds to the outer shape of the new energy vehicle protective shell 80. Further, the support assembly 10 includes multiple pads 14 mounted on the fixing seat 12. The pads 14 are used to support the middle part of the new energy vehicle protective shell 80.

[0025] In one embodiment, the support assembly 10 further includes a protruding edge 15 protruding from the fixing base 12, the protruding edge 15 being disposed along the periphery of the fixing base 12, and a groove 150 forming between the protruding edge 15 and the support block 13. The support assembly 10 also includes support magnets 16 mounted on the fixing base 12. Optionally, there are two support magnets 16, each corresponding to one of the two grooves 120. The support assembly 10 further includes a first fastener 17 and a second fastener 18, both of which are mounted on the fixing base 12. Optionally, there are two second fasteners 18.

[0026] Please check again. Figures 2 to 4The detection component 20 includes a first limiting block 21 and two second limiting blocks 22. The first limiting block 21 is used to insert into the first through hole 811 of the new energy vehicle protective shell 80, and the second limiting block 22 is used to insert into the second through hole 812 of the new energy vehicle protective shell 80. The two second limiting blocks 22 correspond one-to-one with the two second through holes 812. During detection, one end of the first limiting block 21 is inserted into the first fastener 17, and the other end passes through the first through hole 811. One end of the second limiting block 22 is inserted into the second fastener 18, and the other end is inserted into the second through hole 812. If the first limiting block 21 can pass through the first fastener 17 and the first through hole 811, and at the same time, both second limiting blocks 22 can pass through the corresponding second fastener 18 and the corresponding second through hole 812, then the positions of the first through hole 811 and the second through hole 812 are accurate. Furthermore, the first limiting block 21 includes a first pin portion 211, a first positioning portion 212, and a first gripping portion 213 connected in sequence. The first pin portion 211 is used to insert the first fastener 17, and the first positioning portion 212 is set corresponding to the first through hole 811. The second limiting block 22 includes a second pin portion 221, a second positioning portion 222, and a second gripping portion 223 connected in sequence. The second pin portion 221 is used to insert the second fastener 18, and the second positioning portion 222 is set corresponding to the second through hole 812. During testing, if the first pin portion 211 can pass through the first fastener 17, the first positioning portion 212 can pass through the first through hole 811, and at the same time, both second pin portions 221 can pass through the corresponding second fastener 18, and both second positioning portions 222 can pass through the corresponding second through hole 812, then the positions of the first through hole 811 and the second through hole 812 are accurate. Furthermore, if the first positioning part 212 can pass through the first through hole 811, it indicates that the size of the first through hole 811 meets the requirements; if the second positioning part 222 can pass through the second through hole 812, it indicates that the size of the second through hole 812 meets the requirements.

[0027] In one embodiment, the detection component 20 further includes at least two top plates 23, which are respectively installed on two adjacent sides of the fixing base 12. In use, the two sides of the new energy vehicle protective shell 80 are respectively abutted against the two top plates 23 for initial positioning, and then the first limiting block 21 and the second limiting block 22 are inserted. The detection component 20 also includes a gauge 24, one end of which is a go gauge end 241 and the other end is a stop gauge end 242. The go gauge end 241 and the stop gauge end 242 are selectively slidably disposed in the slide groove 150. Optionally, both the go gauge end 241 and the stop gauge end 242 are cylindrical, the diameter of the go gauge end 241 is smaller than the diameter of the stop gauge end 242, and the diameter of the stop gauge end 242 is equal to the width of the slide groove 150. In this embodiment, the edge of the new energy vehicle protective shell 80 that meets the requirements protrudes beyond the edge of each support block 13, that is, the distance between the edge of the new energy vehicle protective shell 80 and the protruding edge 15 is less than the groove width of the slide groove 150. When checking the external dimensions, the new energy vehicle protective shell 80 is placed on the support block 13, and the two sides of the new energy vehicle protective shell 80 abut against the two top plates 23 for preliminary positioning. Then, the first limiting block 21 and the second limiting block 22 are inserted. Next, the go gauge end 241 slides along the gap between the new energy vehicle protective shell 80 and the protruding edge 15. If the go gauge end 241 cannot pass smoothly, it indicates that the size of the new energy vehicle protective shell 80 at that point is too large and does not meet the requirements. The stop gauge end 242 then slides along the gap between the new energy vehicle protective shell 80 and the protruding edge 15. If the go gauge end 241 can be inserted into the slide groove 150, it indicates that the size of the new energy vehicle protective shell 80 at that point is too small and does not meet the requirements.

[0028] like Figures 2 to 5As shown, the assembly component 30 includes a mounting base 31, a push block 32, a support arm 33, a contour block 34, and a robotic arm 35. The mounting base 31 is mounted on the base plate 11. The push block 32 is slidably mounted on the mounting base 31. The support arm 33 is detachably mounted on the push block 32. The contour block 34 is slidably mounted on the support arm 33. The contour block 34 is used to fix the spring hook 85. The robotic arm 35 is used to install the spring hook 85 onto the contour block 34. Optionally, the shape of the cross-section of the contour block 34 corresponds to the shape of the cross-section of one end of the spring hook 85. The cross-sectional dimension of the contour block 34 is larger than the cross-sectional dimension of the card holder 82. The spring hook 85 is widened by the contour block 34 so that the spring hook 85 can be installed onto the card holder 82. Furthermore, a limiting part 341 is provided on one side of the contour block 34, and a locking part 331 is provided on one side of the support arm 33. The locking part 331 is used to abut against the limiting part 341 to prevent the contour block 34 from detaching from the support arm 33. Even further, a guide groove 342 is provided on one side of the contour block 34. The guide groove 342 is a blind groove, and the end of the guide groove 342 away from the limiting part 341 is closed. In one embodiment, one end of the robotic arm 35 is provided with a receiving groove corresponding to one end of the spring hook 85 to accommodate the spring hook 85. A magnet is installed inside the robotic arm 35, and the magnet magnetically attracts the spring hook 85. During assembly, as the push block 32 moves towards the mounting base 82 of the new energy vehicle protective shell 80, one end of the contour block 34 abuts against one end of the mounting base 82, and the push block 32 then pushes the spring hook 85 from the contour block 34 onto the mounting base 82.

[0029] like Figure 5 As shown, the assembly component 30 further includes a guide post 36, one end of which is mounted on the push block 32, and the other end is slidably disposed in the guide groove 342 to limit the sliding of the contour block 34. The sliding of the contour block 34 is limited by the cooperation between the guide post 36 and the guide groove 342, and between the limiting part 341 and the locking part 331, preventing the contour block 34 from detaching from the push block 32. The assembly component 30 also includes an assembly magnet (not shown), which magnetically attracts the support arm 33 to further improve the installation stability. When the contour block 34 is fitted with the spring hook 85, the groove 120 is used to accommodate the support arm 33, and the support arm 33 magnetically attracts the supporting magnet 16 to prevent the support arm 33 from shifting.

[0030] like Figure 2 and Figure 3 As shown, the assembly component 30 also includes supports 37 and pressure blocks 38. Multiple supports 37 and pressure blocks 38 are present and correspond one-to-one. Supports 37 are mounted on the base plate 11, with each support 37 arranged along the periphery of the fixing seat 12. Each pressure block 38 is used to press against the periphery of the new energy vehicle protective shell 80 to prevent the new energy vehicle protective shell 80 from shifting during assembly of the spring hook 85. Optionally, the pressure block 38 is a rubber block; the pressure block 38 is arranged corresponding to the support block 13.

[0031] like Figure 3 As shown, the assembly component 30 also includes a stand 39, a support rod 41, a linkage 42, and a handle 43. The stand 39 is mounted on the support 37. One end of the support rod 41 is pivotally connected to the stand 39, and the pressure block 38 is slidably mounted on the support rod 41 to adjust its position. One end of the linkage 42 is pivotally connected to the support rod 41, and the other end is pivotally connected to the handle 43. One end of the handle 43 is pivotally connected to the stand 39. There are multiple supports 37, stands 39, support rods 41, linkages 42, and handles 43, and they correspond one-to-one. In use, by rotating the handle 43, under the action of the linkage 42, one end of the support rod 41 is driven to rotate around one end of the stand 39, thereby causing the pressure block 38 to move closer to or away from the new energy vehicle protective shell 80. In one embodiment, there are two mounting bases 31, push blocks 32, support arms 33, and contour blocks 34, and they correspond one-to-one. One of the mounting bases 31 is installed inside the fixed base 12.

[0032] During testing, the protective shell 80 of the new energy vehicle is placed on the support block 13, and the two sides of the protective shell 80 are respectively abutted against the two top plates 23 for initial positioning. Then, the first limiting block 21 and the second limiting block 22 are inserted in sequence. If the first fastener 17 can be inserted into one end of the first limiting block 21 and the first through hole 811 can be passed through the other end, and the second fastener 18 can be inserted into one end of the second limiting block 22 and the second through hole 812 can be passed through the other end, then the positions of the first through hole 811 and the second through hole 812 are accurate, and the size of the first through hole 811 and the size of the second through hole 812 meet the requirements. The first limiting block 21 remains inserted in the first fastener 17, and the second limiting block 22 remains inserted in the second fastener 18. Then, the go gauge end 241 slides along the gap between the new energy vehicle protective shell 80 and the raised edge 15. If the go gauge end 241 cannot pass smoothly, it indicates that the size of the new energy vehicle protective shell 80 at that location is too large and does not meet the requirements. The no-go gauge end 242 slides along the gap between the new energy vehicle protective shell 80 and the raised edge 15. If the go gauge end 241 can be inserted into the sliding groove 150, it indicates that the size of the new energy vehicle protective shell 80 at that location is too small and does not meet the requirements.

[0033] After the inspection is completed, the qualified products are assembled with spring hook 85. First, the pressure block 38 is pressed tightly against the new energy vehicle protective shell 80 by the handle 43. Then, the support arm 33 is placed in the groove 120, and the robot arm 35 equipped with spring hook 85 quickly approaches the contour block 34. Since the contour block 34 and spring hook 85 are interference-fitted, and the robot arm 35 and spring hook 85 are magnetically connected, the robot arm 35 installs the spring hook 85 on the contour block 34. Next, the support arm 33 with the spring hook 85 installed is inserted into the push block 32, and then the push block 32 is pushed towards the mounting base 82. As the push block 32 moves, one end of the contour block 34 abuts against one end of the mounting base 82. The push block 32 is then pushed further, and it slides onto the contour block 34, thus pushing the spring hook 85 from the contour block 34 onto the mounting base 82, thereby completing the installation of the spring hook 85. Furthermore, since the cross-section of the contour block 34 is larger than the cross-section of the mounting base 82, it facilitates the installation of the spring hook 85 onto the mounting base 82. This testing and assembly device 100 for protective shells of new energy vehicles integrates testing and assembly functions, eliminating the need for secondary positioning during assembly and improving efficiency.

[0034] A method for testing and assembling a protective shell for new energy vehicles, based on the aforementioned testing and assembly device 100 for new energy vehicle protective shells, comprises the following steps: Hole position detection: Place the new energy vehicle protective shell 80 on the support block 13, and insert the first limiting block 21 and the second limiting block 22 in sequence; if one end of the first limiting block 21 can be inserted into the fixing seat 12 and the other end can pass through the first through hole 811, and one end of the second limiting block 22 can be inserted into the fixing seat 12 and the other end can pass through the second through hole 812, then the positions of the first through hole 811 and the second through hole 812 are accurate, and the size of the first through hole 811 and the size of the second through hole 812 meet the requirements; otherwise, it is treated as a defective product; Optionally, place the new energy vehicle protective shell 80 on the support block 13, and make the two sides of the new energy vehicle protective shell 80 abut against the two top plates 23 for preliminary positioning, and then insert the first limiting block 21 and the second limiting block 22 in sequence; furthermore, one end of the first limiting block 21 can be inserted into the first fastener 17, and one end of the second limiting block 22 can be inserted into the second fastener 18.

[0035] Appearance inspection: After completing the hole position inspection, the first limiting block 21 and the second limiting block 22 remain inserted in the fixed base 12; then, the go gauge end 241 slides along the gap between the new energy vehicle protective shell 80 and the raised edge 15. If the go gauge end 241 cannot pass smoothly, it indicates that the size of the new energy vehicle protective shell 80 at that location is too large and does not meet the requirements; the no-go gauge end 242 slides along the gap between the new energy vehicle protective shell 80 and the raised edge 15. If the go gauge end 241 can be inserted into the sliding groove 150, it indicates that the size of the new energy vehicle protective shell 80 at that location is too small and does not meet the requirements, and is treated as a defective product; optionally, the first limiting block 21 remains inserted in the first fastener 17 and the second limiting block 22 remains inserted in the second fastener 18; Spring hook assembly: After the support arm 33 is placed on the fixed base 12, the robotic arm 35 equipped with the spring hook 85 quickly approaches the contour block 34, thereby installing the spring hook 85 onto the contour block 34. Next, the support arm 33 with the spring hook 85 is inserted into the push block 32, and then the push block 32 is pushed towards the card holder 82. As the push block 32 moves, one end of the contour block 34 abuts against one end of the card holder 82. Continuing to push the push block 32, the push block 32 slides onto the contour block 34, thereby pushing the spring hook 85 from the contour block 34 onto the card holder 82, thus completing the installation of the spring hook 85. Optionally, the pressure block 38 is first pressed against the new energy vehicle protective shell 80 by the handle 43; then, the support arm 33 is placed in the groove 120, and the robotic arm 35 equipped with the spring hook 85 quickly approaches the contour block 34 again.

[0036] The testing and assembly device 100 for protective shells of new energy vehicles of the present invention uses the cooperation of the first limiting block 21 and the second limiting block 22 to test the accuracy of the first through hole 811 and the second through hole 812; the robot arm 35 installs the spring hook 85 onto the contour block 34, and as the push block 32 moves, one end of the contour block 34 abuts against one end of the card seat 82, and the push block 32 then pushes the spring hook 85 from the contour block 34 onto the card seat 82, thereby completing the installation of the spring hook 85 and improving the assembly efficiency; the testing and assembly device 100 for protective shells of new energy vehicles integrates testing and assembly functions, and no secondary positioning is required during assembly.
