Description

Technical Field

[0001] This invention relates to the field of assembly line testing technology, specifically to an automated assembly and testing production line for new energy vehicle covers. Background Technology

[0002] The assembly sequence of new energy vehicle cover molding parts in the production process is generally as follows: surface cleaning, steel sleeve installation, foam application, and finished product packaging. Various quality inspections are interspersed throughout the process, mainly including quality inspection of whether the steel sleeve and foam are installed in place, and airtightness testing of the molding parts.

[0003] Surface cleaning and foam application are done manually, airtightness testing is semi-automatic, and steel sleeve installation is a combination of semi-automatic and manual operations. Product inspection during production is done manually, which can lead to missed inspections or issues that are not detected manually. Furthermore, manual operation makes it difficult to guarantee product consistency and results in low production efficiency. Therefore, modern assembly lines often use dedicated testing equipment to achieve automated production lines.

[0004] While airtightness testing requires additional equipment, the installation quality of steel sleeves and foam often only needs to be inspected visually. However, molded parts have varying shapes, making it difficult to inspect them comprehensively with a single camera. Furthermore, some areas are in shadow, making it difficult for the camera to capture them accurately, thus affecting the inspection accuracy. Summary of the Invention

A force sensor is provided at the connection end of the pull rod and the tension spring. A rotating rod is rotatably connected to the other end of the pull rod. At least one section of a spiral inclined cam groove is machined on the surface of the rotating rod. A brush rod is sleeved on one end of the rotating rod that extends out of the circular groove. At least one radially protruding guide key is provided on the surface of the circular groove in conjunction with the spiral inclined cam groove. The head of the guide key is embedded in the spiral inclined cam groove.

[0009] According to the above technical solution, the positioning block is connected to a suction tube, and a suction pump is connected to the outside of the suction tube.

[0010] According to the above technical solution, an illumination tube is provided inside the illumination block, and a ring of toothed grooves is provided on the outer surface of the illumination tube. A small gear is provided inside the illumination block to rotate in coordination with the toothed grooves. The upper end of the small gear protrudes from the surface of the illumination block. A rack is provided on the upper plate corresponding to the small gear, and the rack and the small gear are engaged.

[0011] According to the above technical solution, cylinders are installed on both sides of the testing platform, and lifting blocks are fixed at the cylinder drive end. The lifting blocks are connected to a support frame, and the lighting box is installed on the support frame.

[0012] According to the above technical solution, the detection mechanism includes a mobile component, a second mounting block is fixed to the driving end of the mobile component, a second driver is provided on the second mounting block, a disk is fixed to the driving end of the second driver, an x-axis is rotatably provided on the lower side of the disk, a first driving component is connected to the x-axis, a y-axis is rotatably provided at both ends of the x-axis, a second driving component is connected to the y-axis, and cameras are provided at both ends of the y-axis.

[0013] According to the above technical solution, a feeding platform is set on one side of the testing platform, a recycling platform is set on one side of the feeding platform, and a discharging platform is set on the other side of the testing platform.

[0015] According to the above technical solution, a lower limit ring and an upper limit ring are spaced apart on the surface of the suction rod. The lower limit ring and the upper limit ring are located on the upper side of the connecting frame. The upper limit ring is connected to a spring, and the other end of the spring is connected to the connecting frame.

[0016] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention, by incorporating a belt-driven mechanism, allows for the flexible movement and reorganization of multiple independent lighting blocks, enabling on-demand allocation of lighting areas, illumination angles, and the number of light sources. This allows the system to quickly adjust the lighting scheme for different products and different inspection areas, providing optimized lighting conditions for high-precision visual inspection and greatly improving defect identification capabilities.

[0017] With the addition of toothed grooves, pinions, and racks, the brush rod automatically deflects and cleans the surface of the lighting tube during the movement of the lighting block, effectively preventing dust and dirt from accumulating on the surface of the light source. This ensures the stability and uniformity of the light intensity, avoids misjudgment caused by light source pollution from the source, and reduces the frequency of manual cleaning and maintenance costs.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-11The present invention provides a technical solution: an automated assembly and testing production line for new energy vehicle covers, comprising a testing platform 1, lighting mechanisms 2 on both sides of the testing platform 1, a testing mechanism 3 mounted on the upper side of the testing platform 1, and a material-grabbing robot 41 and a material-grabbing robot 42 respectively mounted on the other two sides of the testing platform 1. The lighting mechanism 2 includes a lighting box, which is composed of an upper plate 211, a lower plate 212, and two side plates 213. Several lighting blocks 22 are slidably arranged between the upper plate 211 and the lower plate 212. The lighting blocks 22 have positioning grooves 221 on their outward-facing side, and mounting blocks 211 are arranged on both sides of the lower plate 212 corresponding to the direction of the positioning grooves 221. 3. A driver 231 is fixed on the lower side of the mounting block 23. The driving end of the driver 231 passes through the mounting block 23 and is fitted with a driving roller 232. A driven roller 233 is rotatably mounted on the mounting block 23. The driven roller 233 and the driving roller 232 are spaced apart. A belt 234 is connected between the driving roller 232 and the driven roller 233. A mounting block 235 is fixed on the side of the belt 234 facing the positioning groove 221. The mounting block 235 has a receiving groove 2351 corresponding to the positioning groove 221. A positioning block 236 is set in the receiving groove 2351. A cylinder 237 is connected to one side of the positioning block 236. The cylinder 237 is fixed on the mounting block 235.

[0022] In actual operation, the driver 231 controls the rotation of the drive roller 232, causing the belt 234 to move the mounting block 235. When the mounting block 235 moves to correspond with a certain lighting block 22, the cylinder 237 pushes out the positioning block 236 located in the receiving groove 2351, so that the positioning block 236 extends into the positioning groove 221, realizing the indirect connection between the mounting block 235 and the lighting block 22.

[0023] Furthermore, such as Figure 4 , Figure 11 As shown, the mounting block 235 has overlapping plates 2352 fixed on both sides. The overlapping plates 2352 slide with the surface of the upper plate 211 and are used for guiding and limiting the movement of the mounting block 235. The positioning block 236 is chamfered so that the positioning block 236 can extend into the receiving groove 2351. The upper plate 211 and the lower plate 212 have two sliding grooves 214 spaced apart on opposite sides. The upper and lower surfaces of the lighting block 22 have long grooves 222 that cooperate with the sliding grooves 214. Several rollers 223 are provided in the long grooves 222. The surface of the sliding grooves 214 is provided with a pressure detection module.

[0024] The following is a supplementary explanation based on the above structure: When the lighting block 22 needs to be moved, the belt 234 drives the mounting block 235 to the corresponding position, and the positioning block 236 extends into the positioning groove 221 to achieve connection. The movement of the belt 234 drives the lighting block 22 to move on the slide groove 214. After the position is adjusted, the positioning block 236 disengages from the positioning groove 221, and the connection is released. According to the lighting requirements, the light source deflection can be flexibly adjusted and the number of lighting sources can be specifically allocated by moving and arranging the lighting blocks 22. The pressure detection module is used to detect the pressure value generated when the roller 223 passes over the surface of the slide groove 214, and lock the position of the corresponding lighting block 22 in the lighting box. The pressure detection module adopts, but is not limited to, a thin-film pressure sensor. Through an ultra-thin flexible structure, it can be directly pasted on the surface of the slide groove 214 without affecting the normal rolling of the roller 223.

[0025] In one embodiment, such as Figure 5 As shown, a circular groove 224 extending through the front and back is provided at one corner of the lighting block 22. A tension spring 24 is connected to the open end of the circular groove 224 facing the positioning groove 221. A pull rod 25 is connected to the other end of the tension spring 24. A force sensor 26 is provided at the connection end of the pull rod 25 and the tension spring 24. A rotating rod 27 is rotatably connected to the other end of the pull rod 25. At least one section of spiral inclined cam groove 271 is machined on the surface of the rod body of the rotating rod 27. A brush rod 28 is sleeved on one end of the rotating rod 27 that extends out of the circular groove 224. At least one radially protruding guide key 272 is provided on the surface of the circular groove 224 in conjunction with the spiral inclined cam groove 271. The head of the guide key 272 is embedded in the spiral inclined cam groove 271.

[0026] It should be further noted that the pull rod 25 and the rotating rod 27 are preferably made of lightweight materials, and the roller 223 should be positioned to avoid the location of the circular groove 224. Under no external force, the tension spring 24 is in an extended state, at which point the brush rod 28 is biased towards the outside of the lighting block 22, with a distance between the surface of the brush rod 28 and the surface of the lighting block 22. When the tension spring 24 contracts under external force, the pull rod 25 moves synchronously, pulling the brush rod 28 closer to the surface of the lighting block 22. Simultaneously, due to the fixed guide key 272, the spiral inclined cam groove 271 on the rotating rod 27 slides relative to the guide key 272. The inclined surface forces the axial movement into rotational motion of the rotating rod 27 around its own axis, thereby causing the brush rod 28 to deflect at a certain angle. When the external force disappears, under the restoring force of the tension spring 24, the rotating rod 27 returns to its axial position and rotates in the opposite direction through the cooperation of the spiral inclined cam groove 271 and the guide key 272, causing the brush rod 28 to return to its initial position. Force sensor 26 is used to detect the extension and retraction state of tension spring 24. Brush rod 28 has bristles of a certain length on the side facing the lighting block 22.

[0027] In one embodiment, such as Figure 11As shown, the positioning block 236 is connected to a suction tube 238, and a suction pump 225 is connected to the outside of the suction tube 238. The diameter of the nozzle section of the suction tube 238 is smaller than the diameter of the circular groove 224, while the diameter of the body section of the suction tube 238 is larger than the diameter of the circular groove 224. When the cylinder 237 pushes the positioning block 236 into the receiving groove 2351, the nozzle section of the suction tube 238 simultaneously extends into the circular groove 224. When the positioning block 236 is in place, the surface of the body section of the suction tube 238 covers the surface of the circular groove 224, sealing the opening. When the suction pump 225 draws air, the negative pressure in the circular groove 224 increases, and the tension spring 24 contracts. When the suction pump 225 releases air, the negative pressure is released, and the tension spring 24 returns to its original position.

[0028] Furthermore, such as Figure 6 , Figure 7 As shown, an illumination tube 226 is provided inside the illumination block 22. A toothed groove 2261 is provided on the outer surface of the illumination tube 226. A pinion 227 is provided inside the illumination block 22 to rotate in conjunction with the toothed groove 2261. The upper end of the pinion 227 protrudes from the surface of the illumination block 22. A rack 2111 is provided on the upper plate 211 corresponding to the pinion 227. The rack 2111 and the pinion 227 cooperate with each other.

[0029] In actual operation, the lighting cylinder 226 serves as the actual lighting source, and the lighting block 22 is connected to the belt 234. Simultaneously, the brush rod 28 is in contact with the surface of the lighting cylinder 226. The rack 2111 is fixed to the upper plate 211. When the lighting block 22 moves along the slide groove 214, the rack 2111 remains stationary, and the pinion 227 rolls along the rack 2111, thereby driving the lighting cylinder 226 to rotate. The driving source is the movement of the lighting block 22 itself, requiring no additional driving device. While adjusting the position of the lighting block 22, the pinion 227 is driven to rotate by the rack 2111, synchronously driving the entire lighting cylinder 226 to rotate. During rotation, the surface of the lighting cylinder 226 fully contacts the brush rod 28, allowing any impurities or dirt on the surface to be brushed away, ensuring the reliability of the light source. When the lighting block 22 is in position, the connection is released, and the brush rod 28 resets and deviates from the lighting cylinder 226, avoiding any impact on the lighting effect.

[0030] In one embodiment, such as Figure 2 As shown, cylinders 11 are installed on both sides of the testing platform 1. A lifting block 12 is fixed to the driving end of cylinder 11. The lifting block 12 is connected to a support frame 13. The lighting box is installed on the support frame 13.

[0031] like Figure 8As shown, the detection mechanism 3 includes a moving component 31. The driving end of the moving component 31 is fixed with a second mounting block 32. The second mounting block 32 is equipped with a second driver 33. The driving end of the second driver 33 is fixed with a disc 34. An x-axis 35 is rotatably arranged on the lower side of the disc 34. The x-axis 35 is connected to a first driving component 36. A y-axis 37 is rotatably arranged at both ends of the x-axis 35. The y-axis 37 is connected to a second driving component 38. Cameras 39 are arranged at both ends of the y-axis 37.

[0032] In actual operation, the moving component 31 adopts, but is not limited to, a screw motor linkage structure, and is diagonally positioned on the detection platform 1 to control the overall movement of the camera 39. The second driver 33 controls the rotation of the disk 34, thereby adjusting the circumferential direction of the camera 39. The first driver component 36 and the second driver component 38 preferably adopt a gear motor linkage structure, respectively controlling the rotation of the x-axis 35 and y-axis 37, thereby adjusting the detection angle of the camera 39 in two directions and improving the comprehensiveness of the detection.

[0033] like Figure 1 As shown, a feeding platform 5 is set on one side of the detection platform 1, a recycling platform 6 is set on one side of the feeding platform 5, and a discharging platform 7 is set on the other side of the detection platform 1. A first grabbing robot 41 is located between the feeding platform 5 and the detection platform 1, and a second grabbing robot 42 is located between the discharging platform 7 and the detection platform 1.

[0034] Furthermore, such as Figure 9 As shown, a material gripping mechanism 8 is respectively installed on the feeding platform 5 and the recycling platform 6. The material gripping mechanism 8 includes a transverse moving component 811. A longitudinal moving component 812 is provided at the driving end of the transverse moving component 811. A connecting frame 82 is installed at the driving end of the longitudinal moving component 812. Several suction rods 83 are movably arranged on the connecting frame 82. A suction cup 84 is provided at the lower end of the suction rod 83. An air pump is externally connected to the upper end of the suction rod 83.

[0035] Furthermore, such as Figure 10 As shown, a lower limit ring 85 and an upper limit ring 86 are spaced apart on the surface of the suction rod 83. The lower limit ring 85 and the upper limit ring 86 are located on the upper side of the connecting frame 82. The upper limit ring 86 is connected to a spring 87, and the other end of the spring 87 is connected to the connecting frame 82.

[0036] In actual operation, the feeding platform 5 is connected to the discharge port of a processing line. The lateral movement component 811 adopts a belt pulley motor linkage structure, and the longitudinal movement component 812 adopts a screw motor linkage structure to control the lateral and longitudinal movement of the connecting frame 82. The lower limit ring 85 serves as the lower limit of the movement of the suction rod 83. When the lower limit ring 85 is in contact with the connecting frame 82, the suction rod 83 is restricted and cannot move further down. The spring 87 provides a buffer stroke for the suction rod 83, enabling it to adapt to irregular product surfaces and ensuring that all suction cups 84 can effectively adsorb. The first gripping robot 41 is used to grip the product to be inspected on the feeding platform 5 and transfer it to the inspection platform 1. If the quality meets the standard, the second gripping robot 42 transfers it to the discharge platform 7; if the quality does not meet the standard, the first gripping robot 41 transfers it to the recycling platform 6.

[0037] The specific implementation method is as follows: For large-area flat products, light sources need to be paired and symmetrically distributed on both sides of the inspection area. Multiple illumination blocks 22 are evenly distributed above the inspection area. The height of the illumination blocks 22 is adjusted to an appropriate position. This creates a large-area, uniform bright-field illumination, ensuring that the light covers the entire product surface and avoiding localized overexposure or shadows caused by concentrated light sources.

[0038] For products with uneven surfaces, it is necessary to highlight and "eliminate" the shadows cast by the minor bumps and imperfections themselves. Move most or all available light sources to one side of the product and adjust the height of the illumination tube 226 so that the light passes parallel across the product surface. At this point, the shaded side of the protrusion will produce a deep shadow, highlighting the defect.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0040] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
