Description

Technical Field

[0001] The present invention relates to the technical field of new energy product processing, and in particular to a scraping and polishing device based on an SMC composite material new energy upper cover. Background Art

[0002] In existing technology, SMC composite materials are typically polished using manual or traditional mechanical polishing methods. While manual polishing offers flexibility, it is inefficient, and polishing quality is significantly affected by the operator's skill level, making it difficult to ensure consistency. While traditional mechanical polishing devices can improve polishing efficiency, they often suffer from complex structures, difficult adjustments, and poor adaptability to complex shapes. This is particularly true when polishing precision components such as new energy battery covers, where traditional methods struggle to meet the high precision and efficiency requirements.

[0003] Furthermore, SMC materials possess unique physical and chemical properties, resulting in high surface hardness and excellent wear resistance. However, this also increases the difficulty of polishing. Improper control of scraping force during the polishing process can easily lead to surface damage or over-polishing, affecting the final product quality. Therefore, developing a polishing device that can precisely control scraping force and accommodate SMC products of varying shapes and sizes is crucial for improving the processing quality and production efficiency of components such as new energy battery top covers.

[0004] At present, there is a lack of scraping and grinding devices specifically for SMC composite material new energy upper covers on the market. Most of the existing technologies have the following shortcomings: first, the grinding accuracy is not high, which makes it difficult to meet the high-precision processing requirements; second, the equipment structure is complex, the operation is cumbersome, and the maintenance cost is high; third, the manual trimming proficiency is inconsistent and the trimming stability is poor. Therefore, it is necessary to design a scraping and grinding device based on SMC composite material new energy upper covers. Summary of the Invention

[0005] The purpose of the present invention is to provide a scraping and polishing device for a new energy upper cover based on SMC composite material to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a scraping and polishing device based on an SMC composite material new energy upper cover, comprising a frame, a processing chamber is arranged on the top of the frame, and a revolving door is arranged on a bearing on the front wall of the processing chamber. When the processing chamber is needed, the revolving door can be flipped up. A transfer assembly is arranged in the processing chamber, and the transfer assembly includes a first vertical frame and a second vertical frame fixedly mounted on the top of the frame, a first sliding rail is longitudinally mounted on the top of the first vertical frame, and a second sliding rail is longitudinally mounted on the top of the second vertical frame, the first sliding rail and the second sliding rail are synchronously slidably connected to a horizontal support column, and a first motor connected to the horizontal support column is arranged at the end of the second vertical frame.

[0007] According to the above technical solution, first side grooves are provided on both side walls of the second sliding track, and the first side grooves on both sides are slidably connected to two inwardly bent first sliding supports provided at the bottom of the transverse support column. A top groove is provided on the top of the second sliding track, and the top groove is slidably connected to a roller provided at the bottom of the transverse support column and located between the two first sliding supports.

[0008] According to the above technical solution, four sets of clamping plates are symmetrically arranged at both ends of the second sliding track. The clamping plates limit the running track area of the horizontal support column so that the scraping and grinding components will not touch the revolving door and the processing chamber.

[0009] According to the above technical solution, a third sliding track is fixedly installed on the top of the horizontal support column, and second side grooves are provided on both side walls of the third sliding track. The second side grooves are slidably connected to two inwardly bent second sliding supports set at the bottom of the support plate. The third sliding support is slidably connected in the second side grooves. An electric control rod is installed on the end bearing of the third sliding support, and a baffle is fixedly installed on the electric control rod. A second motor connected to the second and third sliding supports is provided at the end of the third sliding track. When the support plate needs to be moved, the baffle can be flipped down. When the support plate needs to be fixed or restricted, the baffle can be flipped up.

[0010] According to the above technical solution, the third sliding rail is slidably connected to the support plate, and the scraping and grinding assembly includes a supporting plate welded on the side wall of the support plate. The supporting plate is concave, and the two protruding areas at the bottom are respectively provided with a scraping assembly and a grinding assembly.

[0011] According to the above technical solution, the scraping assembly includes a fourth sliding rail fixed on the side wall of the supporting plate, and the fourth sliding rail is slidably connected to the camera assembly, which monitors the processing of the upper cover. If an upper cover processing error occurs, that is, the upper cover is processed and damaged beyond a preset range or a preset degree, the processing process is stopped immediately.

[0012] According to the above technical solution, a splint is fixedly installed at the bottom of the fourth sliding track, a circular warehouse is fixedly installed at the bottom of the splint, and three groups of lifting chutes are set on the side walls of the circular warehouse. A group of scraping spring heads are slidably connected in each lifting chute.

[0013] According to the above technical solution, a plurality of pressure sensors are evenly arranged on the outer side wall of the scraping spring head from top to bottom.

[0014] According to the above technical solution, the grinding assembly includes a hydraulic press fixed on the side wall of the bearing plate, a base block is fixedly installed on the output end of the hydraulic press, and a plurality of third motors are fixedly installed in the base block, and the output end of each third motor is downward and fixedly installed with a circular grinding head;

[0015] Four groups of short rails are arranged around the bottom of the base block, and a square grinding head is slidably connected to each group of short rails.

[0016] According to the above technical solution, a touch screen is provided on the side of the processing chamber. The touch screen is a liquid crystal screen and can be directly operated manually on the touch screen.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention, by providing a scraping assembly, ensures that only the pressure sensor at the bottom of the scraping spring head always remains in contact with the protruding structure, that is, ensures that the thickness of the protruding structure scraped each time is thinner. This method of multiple scrapings but a small amount of single scraping can ensure that the position of the upper cover will not be deviated by the pressure of the scraping spring head, and can also ensure that the scraping spring head has high scraping accuracy each time. Furthermore, it can also ensure that the scraping spring head has a long service life. If all protruding structures of all heights are scraped in one time, there is a possibility that the scraping spring head will damage the non-protruding structure part of the upper cover.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-11 The present invention provides a technical solution: a scraping and polishing device based on an SMC composite material new energy upper cover, comprising a frame 1. Specifically, a processing chamber 2 for scraping and polishing an upper cover 31 is provided on the top of the frame 1, a revolving door 3 is provided on the front of the processing chamber 2, and the top of the revolving door 3 is connected to the processing chamber 2 through a door shaft. When the upper cover 31 needs to be moved, the revolving door 3 can be flipped up in advance, so that the entire processing process is carried out in a relatively sealed environment, and dust will not overflow.

[0033] Specifically, a touch screen 4 is provided on the side of the processing chamber 2 , wherein the touch screen 4 is used for manually adjusting the structure in the processing chamber 2 , and then scraping and polishing the upper cover 31 , and is also used to display the status of the upper cover 31 during the scraping and polishing process.

[0034] Specifically, a transfer assembly 5 with lateral and longitudinal movement functions is provided in the processing chamber 2. The transfer assembly 5 includes two symmetrical first upright frames 6 and second upright frames 7 fixedly mounted on the top of the frame 1. A first sliding rail 8 is longitudinally fixedly mounted on the top of the first upright frame 6, and a second sliding rail 9 is longitudinally fixedly mounted on the top of the second upright frame 7. The first sliding rail 8 and the second sliding rail 9 are synchronously slidably connected to a transverse support column 10. A first motor 11 connected to the transverse support column 10 is provided at the end of the second upright frame 7. By driving the first motor 11 to operate, the transverse support column 10 slides longitudinally along the first sliding rail 8 and the second sliding rail 9.

[0035] The width of the second sliding track 9 is greater than that of the first sliding track 8. The purpose is to increase the contact area between the transverse support column 10 and the second sliding track 9, thereby increasing the area of the energized end of the transverse support column 10 and stabilizing the energy supply of the transverse support column 10.

[0036] Among them, there are two sliding connection methods between the second sliding rail 9 and the horizontal support column 10. The first is to set first side grooves 14 on both side walls of the second sliding rail 9, and the first side grooves 14 on both sides are slidably connected with two inwardly bent first sliding supports 15 arranged at the bottom of the horizontal support column 10, and the first motor 11 supplies energy to the first sliding supports 15. The second is to set a top groove 16 on the top of the second sliding rail 9, and the top groove 16 is slidably connected with a roller arranged at the bottom of the horizontal support column 10 and located between the two first sliding supports 15. The second sliding connection method is to improve the sliding smoothness of the horizontal support column 10, and to appropriately reduce the power consumption of the first motor 11, so that the heavy horizontal support column 10 can be driven to slide stably with less energy consumption;

[0037] Among them, four sets of clamping plates 12 are symmetrically arranged at both ends of the second sliding track 9. The clamping plates 12 can effectively limit the running track area of the horizontal support column 10, preventing the scraping and grinding components 13 arranged on the horizontal support column 10 from touching the inner wall of the revolving door 3 and the processing chamber 2;

[0038] Among them, a third sliding rail 17 is fixedly installed on the top of the horizontal support column 10, and the third sliding rail 17 is slidably connected to the support plate 19. The scraping and grinding assembly 13 is arranged on the support plate 19. The connection between the third sliding rail 17 and the support plate 19 is as follows: second side grooves 18 are provided on the side walls of both sides of the third sliding rail 17, and two inwardly bent second sliding supports 20 arranged at the bottom of the support plate 19 are slidably connected on the second side grooves 18. A third sliding support 21 is also slidably connected in the second side grooves 18, and an electric control rod 22 is installed on the end bearing of the third sliding support 21. A baffle 23 is fixedly installed on the electric control rod 22, and a second motor 24 connected to the second sliding support 20 and the third sliding support 21 is provided at the end of the third sliding rail 17. By driving the second motor 24 to operate, the support plate 19 slides horizontally along the third sliding rail 17;

[0039] When the baffle 23 is rotated upward to a position perpendicular to the horizontal support column 10, the top position of the baffle 23 is higher than the bottom position of the support plate 19, thereby limiting the sliding trajectory of the support plate 19. When there is no need for the baffle 23 to limit the position of the support plate 19, the electric control rod 22 is driven to operate and drive the baffle 23 to rotate downward. The lateral running trajectory of the scraping and grinding assembly 13 can be controlled by adjusting the baffle 23. The baffles 23 on both sides of the support plate 19 can also be controlled to form a clamping state for the support plate 19, thereby improving the stability of the support plate 19 when it is not in operation, thereby improving the processing and operation stability of the scraping and grinding assembly 13. This arrangement can reduce the number of structures arranged on the horizontal support column 10, and at the same time complete the two functions of limiting the sliding trajectory of the scraping and grinding assembly 13 and improving the operation stability of the scraping and grinding assembly 13.

[0040] The scraping and grinding assembly 13 includes a carrier plate 25 welded to the side wall of the support plate 19. The carrier plate 25 is concave, and two protruding areas at the bottom are respectively provided with a scraping assembly 26 and a grinding assembly 27. The scraping assembly 26 includes a fourth sliding track 28 fixed to the side wall of the carrier plate 25. The fourth sliding track 28 is slidably connected to the camera assembly 29. In this embodiment, the camera assembly 29 is a conventional structure, and its function is to monitor the upper cover 31 being processed below in real time and transmit the acquired information to the equipment system.

[0041] Among them, the bottom of the fourth sliding rail 28 is fixedly installed with a clamping plate 30, and the bottom of the clamping plate 30 is fixedly installed with a circular bin 33. Three sets of lifting slots 34 are provided on the side walls of the circular bin 33, and each lifting slot 34 is slidably connected with a set of scraping spring heads 32. When processing the upper cover 31, the scraping spring heads 32 are pressed on the upper cover 31 by springs, and then the surface of the upper cover 31 is scraped. The purpose of scraping is to remove the protruding parts of the surface of the upper cover 31. The three sets of scraping spring heads 32 are driven by the equipment system to descend along the lifting slots 34 until the scraping spring heads 32 contact the surface of the upper cover 31, and then the scraping spring heads 32 are driven to move longitudinally by driving the horizontal support column 10, and the scraping spring heads 32 are driven to move horizontally by driving the support plate 19, so that the scraping spring heads 32 can scrape the surface of the upper cover 31;

[0042] Among them, a plurality of pressure sensors 35 are evenly arranged on the outer wall of the scraping spring head 32 from top to bottom. In the process of the scraping spring head 32 scraping the upper cover 31, it will contact the protruding structure on the surface of the upper cover 31. As the scraping spring head 32 scrapes the protruding structure, the pressure sensors 35 on its outer wall will contact the protruding structure. Different scraping processes are adopted according to the number of pressure sensors 35 on the same scraping spring head 32 that are contacted by the protruding structure. If the protruding structure only contacts the pressure sensor 35 at the bottom of the scraping spring head 32, the scraping spring head 32 continues to operate until the scraping process is completely completed. If the protruding structure contacts the pressure sensors 35 other than the pressure sensor 35 at the bottom of the scraping spring head 32, it means that the protruding structure that the scraping spring head 32 is scraping at this time has a higher protruding height. At this time, the equipment system drives the scraping spring head 32 along the lifting slide 3 4 rises, and the rising distance is determined by the number of pressure sensors 35 that the protruding structure contacts except the lowest pressure sensor 35 of the scraping spring head 32. The equipment system presets the distance H for a single pressure sensor 35 to be contacted and raised. The equipment system drives the scraping spring head 32 to rise by a distance that ensures that only the lowest pressure sensor 35 of the scraping spring head 32 always keeps in contact with the protruding structure, that is, ensures that the thickness of the protruding structure scraped each time is relatively thin. This method of multiple scraping but small single scraping amount can ensure that the position of the upper cover 31 will not be deviated by the pressure of the scraping spring head 32, and can also ensure that the scraping spring head 32 has high scraping accuracy each time. Moreover, it can also ensure a long service life of the scraping spring head 32. If all protruding structures of all heights are scraped in one go, there is a possibility that the scraping spring head 32 will damage the non-protruding structure part of the upper cover 31.

[0043] The grinding assembly 27 includes a hydraulic press 36 fixed to the side wall of the carrier plate 25. A base block 37 is fixedly mounted on the output end of the hydraulic press 36. A plurality of third motors 38 are fixedly mounted in the base block 37. The output end of each third motor 38 faces downward and is fixedly mounted with a circular grinding head 39. After the scraping assembly 26 completes its work, the scraping assembly 26 is reset, and the equipment system drives the hydraulic press 36 to operate and drive the base block 37 to descend. The descending base block 37 drives the circular grinding head 39 to contact the upper cover 31. Then, the third motor 38 is driven to drive the circular grinding head 39 to rotate and grind the surface of the upper cover 31. The grinding time, number of grinding times, etc. can be preset in the equipment system.

[0044] Among them, the output end of the third motor 38 has a telescopic function, so that the circular grinding head 39 can be raised and lowered. When the circular grinding head 39 needs to be used, the circular grinding head 39 is lowered to the lowest point in advance by the equipment system, so that the circular grinding head 39 protrudes from all structures at the bottom of the base block 37, so as to facilitate the completion of the first step of grinding. Four sets of short rails 40 are set around the bottom of the base block 37, and each set of short rails 40 is slidably connected to the square grinding head 41. After the circular grinding head 39 finishes grinding, the equipment system drives the circular grinding head 39 to reset, and moves the square grinding head 41 to the edge of the upper cover 31 through the horizontal support column 10 and the support plate 19, and then drives the square grinding head 41 to move on the short rails 40 to grind the upper cover 31, and cooperates with the movement of the upper horizontal support column 10 and the support plate 19 to perform the second step of grinding on the upper cover 31 to complete the grinding of the edge of the upper cover 31;

[0045] The square grinding head 41 is connected to a power supply mechanism 49 provided in the base block 37 , and the square grinding head 41 is driven to operate by driving the power supply mechanism 49 .

[0046] Specifically, a support frame 42 is fixedly installed on the top of the processing chamber 2, and a fourth motor 43 is provided on both sides of the support frame 42. A support plate 44 is fixedly installed on the output end of the fourth motor 43, and an adsorption component 45 is provided on the support plate 44. The adsorption component 45 includes a concave hole 46 provided on the support plate 44, and a lifting rod 47 is fixedly installed in the concave hole 46. An electromagnet 48 is fixedly installed on the top of the lifting rod 47. After the upper cover 31 is placed on the support plate 44, the equipment system drives the lifting rod 47 to rise, driving the electromagnet 48 to rise until it is close to the upper cover 31, and then drives the electromagnet 48 to energize and adsorb the upper cover 31, thereby completing the fixation of the upper cover 31;

[0047] When the scraping assembly 26 is scraping the upper cover 31, if there is a need to grind the edge of the upper cover 31, the fourth motor 43 is driven to rotate by the equipment system, driving the support plate 44 to rotate the upper cover 31 to an angle perpendicular to the ground, and then the scraping assembly 26 is driven to scrape the edge of the upper cover 31, and the grinding assembly 27 grinds the edge of the upper cover 31, and the above process is repeated;

[0048] Among them, the processing flow of the upper cover 31 is to first perform a scraping process on the upper cover 31, and then rotate the processed surface of the upper cover 31 to face downward by driving the support plate 44 to rotate, and clean the upper cover 31 through the combination of gravity and rotation, and then perform a grinding process on the upper cover 31. During the grinding process, the power consumption of the third motor 38 and the power supply mechanism 49 is monitored by the equipment system. If the power consumption of the third motor 38 and the power supply mechanism 49 increases, it means that there is still a protruding structure on the surface of the upper cover 31. At this time, the scraping process is repeated in advance, and the automatic grinding and scraping path planning are combined to realize fully automated grinding operations, reduce manual intervention until the final grinding process is completed.
