Technical Field

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

[0002] In the prior art, manual polishing or traditional mechanical polishing is often used for the polishing of SMC composite products. Although manual polishing is highly flexible, it is inefficient, and the polishing quality is greatly affected by the skill level of the operator, making it difficult to ensure consistency. Although traditional mechanical polishing devices can improve polishing efficiency, they often have problems such as complex structure, inconvenient adjustment, and poor adaptability to complex shapes. Especially in the polishing process of precision parts such as new energy battery covers, traditional methods are difficult to meet the requirements of high precision and high efficiency.

[0003] In addition, SMC materials have unique physical and chemical properties, with high surface hardness and good wear resistance, but at the same time, it also increases the difficulty of grinding. During the grinding process, if the scraping force is not properly controlled, it is easy to cause surface damage or excessive grinding of the material, affecting the final quality of the product. Therefore, developing a grinding device that can accurately control the scraping force and adapt to SMC products of different shapes and sizes is of great significance for improving the processing quality and production efficiency of new energy battery covers and other components.

[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, and it is 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

A top groove is arranged on the top of the second sliding track, and the top groove is slidably connected to a roller arranged 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, and 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 scheme, a third sliding track is fixedly installed on the top of the horizontal support column, and second side grooves are arranged on the side walls on both sides of the third sliding track. The second side grooves are slidably connected to two second sliding supports bent inwardly arranged at the bottom of the support plate, and 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 arranged 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 bearing plate welded on the side wall of the support plate. The bearing 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.

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 head has high precision each time scraping. Furthermore, it can also ensure that the scraping spring head has a long service life. If all protruding structures of all heights are scraped at one time, there is a possibility that the scraping spring head will damage the non-protruding structure part of the upper cover.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-11 The present invention provides a technical solution: a scraping and grinding device based on an SMC composite material new energy upper cover, comprising a frame 1. Specifically, a processing chamber 2 for scraping and grinding an upper cover 31 is arranged on the top of the frame 1, a revolving door 3 is arranged 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.

[0020] 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 for displaying the state of the upper cover 31 during the scraping and polishing process.

[0021] Specifically, a transfer assembly 5 with lateral and longitudinal movement functions is arranged in the processing chamber 2, and the transfer assembly 5 includes two symmetrical first frames 6 and second frames 7 fixedly mounted on the top of the frame 1, a first sliding track 8 is longitudinally fixedly mounted on the top of the first frame 6, and a second sliding track 9 is longitudinally fixedly mounted on the top of the second frame 7, a transverse support column 10 is synchronously slidably connected to the first sliding track 8 and the second sliding track 9, and a first motor 11 connected to the transverse support column 10 is arranged at the end of the second frame 7, and the first motor 11 is driven to operate, so that the transverse support column 10 slides longitudinally along the first sliding track 8 and the second sliding track 9; The width of the second sliding track 9 is greater than that of the first sliding track 8, the purpose of which is to increase the contact area between the transverse support column 10 and the second sliding track 9, so that the area of ​​the powered end of the transverse support column 10 is increased, so that the energy receiving of the transverse support column 10 is stable; Among them, there are two sliding connection modes between the second sliding track 9 and the transverse support column 10. The first is to set first side grooves 14 on the side walls of the second sliding track 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 transverse 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 track 9, and the top groove 16 is slidably connected with a roller arranged at the bottom of the transverse support column 10 and located between the two first sliding supports 15. The second sliding connection mode is set to improve the sliding smoothness of the transverse support column 10, and is also to appropriately reduce the power consumption of the first motor 11, so that the heavy transverse support column 10 can be driven to slide stably with less energy consumption; Among them, four groups of card plates 12 are symmetrically arranged at both ends of the second sliding track 9, and the card plates 12 can effectively limit the running track area of ​​the horizontal support column 10, so as to prevent 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; Among them, a third sliding track 17 is fixedly installed on the top of the horizontal support column 10, and a support plate 19 is slidably connected to the third sliding track 17. The scraping and grinding assembly 13 is arranged on the support plate 19. The connection method between the third sliding track 17 and the support plate 19 is that second side grooves 18 are arranged on the side walls of both sides of the third sliding track 17, and two inwardly bent second sliding supports 20 arranged at the bottom of the support plate 19 are slidably connected to 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. A second motor 24 connected to the second sliding support 20 and the third sliding support 21 is arranged at the end of the third sliding track 17. By driving the second motor 24 to operate, the support plate 19 slides horizontally along the third sliding track 17; The baffle plate 23 is driven to rotate 180 degrees up and down by driving the electric control rod 22. When the baffle plate 23 rotates upward to a state perpendicular to the horizontal support column 10, the top position of the baffle plate 23 is higher than the bottom position of the support plate 19, thereby limiting the sliding trajectory of the support plate 19. When the baffle plate 23 is not needed to limit the position of the support plate 19, the electric control rod 22 is driven to rotate downward. The lateral running trajectory of the scraping and grinding assembly 13 is controlled by adjusting the baffle plate 23. The baffle plates 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 running, thereby improving the processing and running stability of the scraping and grinding assembly 13. This arrangement can reduce the number of structures arranged on the horizontal support column 10, and simultaneously complete the two functions of limiting the sliding trajectory of the scraping and grinding assembly 13 and improving the running stability of the scraping and grinding assembly 13. The scraping and grinding assembly 13 includes a carrier plate 25 welded on 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 on the side wall of the carrier plate 25, and a camera assembly 29 is slidably connected to the fourth sliding track 28. In this embodiment, the camera assembly 29 is a prior art 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; Among them, a clamping plate 30 is fixedly installed at the bottom of the fourth sliding track 28, and a round bin 33 is fixedly installed at the bottom of the clamping plate 30. Three groups of lifting slots 34 are arranged on the side walls of the round bin 33. A group of scraping elastic heads 32 are slidably connected in each lifting slot 34. When processing the upper cover 31, the scraping elastic heads 32 are pressed on the upper cover 31 by a spring, 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 groups of scraping elastic heads 32 are driven to descend along the lifting slots 34 by the equipment system until the scraping elastic heads 32 contact the surface of the upper cover 31, and then the scraping elastic heads 32 are driven to move longitudinally by driving the horizontal support column 10, and the scraping elastic heads 32 are driven to move horizontally by driving the support plate 19, so that the scraping elastic heads 32 can scrape the surface of the upper cover 31. 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. When the scraping spring head 32 scrapes 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 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 run 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 height of the protruding structure that the scraping spring head 32 is scraping at this time is relatively high, and 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 contacted by the protruding structure except the lowest pressure sensor 35 of the scraping elastic head 32. The equipment system presets the rising distance of a single pressure sensor 35 as H. The equipment system drives the scraping elastic head 32 to rise by a distance to ensure that only the lowest pressure sensor 35 of the scraping elastic head 32 always keeps in contact with the protruding structure, that is, to ensure that the thickness of the protruding structure scraped each time is relatively thin. This method of multiple scrapings but a small amount of scraping in a single time can ensure that the position of the upper cover 31 will not be deviated by the pressure of the scraping elastic head 32, and can also ensure that the scraping elastic head 32 has high scraping accuracy each time. Moreover, it can also ensure that the scraping elastic head 32 has a long service life. If all protruding structures of all heights are scraped at a single time, the scraping elastic head 32 may damage the non-protruding structure part of the upper cover 31. The grinding assembly 27 includes a hydraulic press 36 fixed on the side wall of the carrier plate 25, a base block 37 is fixedly installed on the output end of the hydraulic press 36, a plurality of third motors 38 are fixedly installed in the base block 37, the output end of each third motor 38 is downward and a circular grinding head 39 is fixedly installed, after the scraping assembly 26 completes the work, the scraping assembly 26 is reset, the equipment system drives the hydraulic press 36 to drive the base block 37 to descend, the base block 37 descends and drives the circular grinding head 39 to contact the upper cover 31, and then drives the third motor 38 to drive the circular grinding head 39 to rotate to grind the surface of the upper cover 31, and the grinding time, grinding times, etc. can be preset in the equipment system; 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 is needed, the circular grinding head 39 is lowered to the lowest point in advance through 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 complete the first step of grinding. Four groups of short rails 40 are arranged around the bottom of the base block 37, and each group of short rails 40 is slidably connected to a square grinding head 41. After the circular grinding head 39 is finished 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; The square grinding head 41 is connected to a power supply mechanism 49 disposed in the base block 37 , and the square grinding head 41 is driven to operate by driving the power supply mechanism 49 .

[0022] Specifically, a support frame 42 is fixedly installed on the top of the processing warehouse 2, and a fourth motor 43 is arranged 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 arranged on the support plate 44. The adsorption component 45 includes a concave hole 46 arranged 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; When the scraping assembly 26 scrapes 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; 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, clean the upper cover 31 by the cooperation 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, and the automatic grinding and scraping path planning are combined to realize fully automated grinding operations and reduce manual intervention until the final grinding process is completed.
