Description

Technical Field

[0001] This invention relates to the field of chamfering equipment technology, and more specifically to an automatic chamfering device for permanent magnets. Background Technology

[0002] The traditional method for chamfering the short sides of NdFeB materials is manual chamfering. Due to the specific requirements of traditional production lines, this step cannot be used, necessitating manual assistance. The traditional method involves manually collecting and stacking materials from the previous process. Chamfering is performed on a separate grinding wheel, requiring multiple flips for each material, resulting in low efficiency. The close proximity of employees' hands to the grinding wheel poses safety risks. Furthermore, the magnetic putty left after manual chamfering can easily remain in the air, posing a health hazard if inhaled. Additionally, uneven force during manual chamfering can lead to excessively large or even tilted chamfers, affecting the quality of the material's chamfering. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the present invention provides an automatic chamfering device for permanent magnets.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An automatic chamfering device for permanent magnets includes a conveying mechanism, a pushing mechanism, a chamfering mechanism, a material sorting mechanism, and a flipping mechanism. The conveying mechanism includes a first conveying mechanism, a second conveying mechanism, and a third conveying mechanism. The first conveying mechanism is used to convey the workpiece to the pushing mechanism, which is located at the outlet of the first conveying mechanism. The pushing mechanism is used to convey the workpiece to the second conveying mechanism. The chamfering mechanism is located at the second conveying mechanism and is used to chamfer the workpiece. The third conveying mechanism is used to convey the chamfered workpiece to the material sorting mechanism. The material sorting mechanism is used to convey the workpieces one by one to the flipping mechanism, which is used to flip the workpieces.

[0005] Based on the above technical solution, the present invention can further improve the above technical solution as follows:

[0006] Preferably, it also includes a feeding and conveying mechanism, which includes a first flip plate, a second flip plate, and a first base plate. The first flip plate is provided on one side of the first base plate, and the second flip plate is provided on the other side. The first flip plate and the second flip plate gradually flip from a horizontal state to a vertical state along the conveying direction of the workpiece.

[0007] Preferably, the first conveying mechanism includes a drive motor and a conveyor belt. The output end of the drive motor is connected to the conveyor belt and drives the conveyor belt to transport the workpiece at the loading and conveying mechanism to the pushing mechanism.

[0008] Preferably, the pushing mechanism includes a drive cylinder and a sensor. The output end of the drive cylinder is connected to a push rod, which drives the push rod to transport the workpiece to the second conveying mechanism. The sensor is used to detect the workpiece and transmit the signal to the drive cylinder.

[0009] Preferably, the second conveying mechanism includes a conveying trough and a pressure plate, the conveying trough and the pressure plate extending from the pushing mechanism to the third conveying mechanism, the pressure plate being located above the conveying trough, and the pressure plate being used to keep the workpiece in an upright state.

[0010] Preferably, the chamfering mechanism includes two grinding wheels, with one grinding wheel on each side of the conveying groove, and the grinding wheels are used to chamfer the workpiece.

[0011] Preferably, the third conveying mechanism includes a support plate and a guide cover disposed on the support plate, the guide cover and the support plate cooperating to form a "U" shape.

[0012] Preferably, the material distribution mechanism includes a second drive cylinder and a second sensor.

[0013] Preferably, the flipping mechanism includes a flipping plate three, a flipping plate four, and a base plate two. The flipping plate three is located on one side of the base plate two, and the flipping plate four is located on the other side of the base plate two. The flipping plate three and the flipping plate four gradually flip from a vertical state to a horizontal state along the conveying direction of the workpiece.

[0014] Preferably, it also includes a feeding conveyor mechanism, which is located at the discharge port of the flipping mechanism. The feeding conveyor mechanism includes a second drive motor and a second conveyor belt, and the output end of the second drive motor is connected to the second conveyor belt for transmission.

[0015] The beneficial effects of this invention are as follows: The workpiece is conveyed to the chamfering mechanism via a feeding and conveying mechanism, a pushing mechanism, and a conveying mechanism, where it is automatically chamfered.

[0021] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0022] like Figures 1 to 4 As shown, this invention discloses an automatic chamfering device for permanent magnets, including a frame 1 and a conveying mechanism mounted on the frame 1. It also includes a pushing mechanism, a chamfering mechanism, a sorting mechanism, and a flipping mechanism mounted on the frame 1. The conveying mechanism includes a first conveying mechanism, a second conveying mechanism, and a third conveying mechanism. The first conveying mechanism is used to convey workpieces 22 to the pushing mechanism, which is located at the outlet of the first conveying mechanism. Further, the pushing mechanism is located on one side of the outlet of the first conveying mechanism, and the second conveying mechanism is located on the other side of the outlet of the first conveying mechanism. The pushing mechanism is used to convey workpieces 22 to the second conveying mechanism. The chamfering mechanism is located at the second conveying mechanism and is used to chamfer the workpieces 22. The third conveying mechanism is used to convey the chamfered workpieces 22 to the sorting mechanism, which is used to convey the workpieces 22 one by one to the flipping mechanism, which is used to flip the workpieces 22.

[0023] When the previous process conveys the vertical workpiece 22 to the automatic chamfering equipment, the first conveying mechanism directly conveys the vertical workpiece 22 to the pushing mechanism, and the pushing mechanism conveys the workpiece 22 to the chamfering mechanism for chamfering, thus meeting the usage requirements under different working conditions.

[0024] In this embodiment, the previous process feeds a horizontal workpiece 22 to the automatic chamfering equipment. The workpiece 22 has a cubic structure. The automatic chamfering equipment also includes a feeding and conveying mechanism, which includes a first flipping plate 2, a second flipping plate 3, and a first base plate 4. The first flipping plate 2 is located on one side of the first base plate 4, and the second flipping plate 3 is located on the other side. The first flipping plate 2 and the second flipping plate 3 gradually flip from a horizontal state to a vertical state along the conveying direction of the workpiece 22. At the feed inlet of the feeding and conveying mechanism, the first flipping plate 2, the second flipping plate 3, and the workpiece 22 are all in a horizontal state. When multiple workpieces 22 are placed one by one at the feed inlet of the feeding and conveying mechanism, the subsequent workpieces 22 push the preceding workpieces 22 to move along the first flipping plate 2 and the second flipping plate 3. During the movement, the workpieces 22 gradually flip from a horizontal state to a vertical state. There is no need for manual flipping of the workpieces 22, which reduces labor intensity, saves labor costs, and enables the chamfering equipment to be connected to the workpiece 22 processing production line, thereby improving the overall processing efficiency of the workpieces 22.

[0025] Furthermore, at the feed inlet, the workpiece 22 is placed flat on the tilting plate 2. The height of the tilting plate 2 is greater than the height of the workpiece 22, ensuring the smooth transport of the workpiece 22 and preventing the workpiece 22 from falling.

[0026] Furthermore, the first flip plate 2 and the second flip plate 3 are detachably mounted on the frame 1, and the distance between the first flip plate 2 and the second flip plate 3 can be adjusted to meet the conveying requirements of workpieces 22 of different sizes and improve the applicability.

[0027] Specifically, the first conveying mechanism includes a drive motor 5 and a conveyor belt 6. The output end of the drive motor 5 is connected to the conveyor belt 6, and drives the conveyor belt 6 to transport the workpiece 22 from the loading conveyor to the pushing mechanism. When the drive motor 5 is working, it drives the conveyor belt 6 to rotate, thereby transporting the vertically positioned workpiece 22 to the pushing mechanism, realizing automatic transport of the workpiece 22 and improving processing efficiency. To prevent the vertically positioned workpiece 22 from tilting during transport, baffles 23 are provided on both sides of the workpiece 22 to ensure normal transport of the workpiece 22.

[0028] The pushing mechanism includes a drive cylinder 7 and a sensor 9. The output end of the drive cylinder 7 is connected to a pushing rod 8, which drives the push rod 8 to transport the workpiece 22 to the second conveying mechanism. The sensor 9 detects the workpiece 22 and transmits a signal to the drive cylinder 7. The sensor 9 is a proximity sensor; when it detects the workpiece 22, it transmits a signal to the drive cylinder 7, which then drives the push rod 8 to move, pushing the workpiece 22 to the second conveying mechanism. The direction of movement of the push rod 8 is perpendicular to the discharge direction of the first conveying mechanism, directly pushing the workpiece 22 output from the first conveying mechanism to the second conveying mechanism. This simplifies operation and improves conveying efficiency. By driving the push rod 8 to reciprocate, the workpiece 22 is continuously transported to the second conveying mechanism, improving the processing efficiency of the workpiece 22.

[0029] In this embodiment, the second conveying mechanism includes a conveying trough 10 and a pressure plate 11. The conveying trough 10 and the pressure plate 11 extend from the pushing mechanism to the third conveying mechanism. The pressure plate 11 is located above the conveying trough 10. The pressure plate 11 and the conveying trough 10 cooperate to form a space for the workpiece 22 to pass through, ensuring that the multiple workpieces 22 in the conveying trough 10 are always in an upright state. The structure of the pressure plate 11 can prevent the workpiece 22 from tilting during conveying. Through the cooperation of the conveying trough 10 and the pressure plate 11, the vertical workpiece 22 is conveyed to the chamfering mechanism, ensuring that the workpiece 22 is properly chamfered.

[0030] Furthermore, two limiting plates 24 are detachably mounted on the frame 1. The two limiting plates 24 cooperate to form a conveying trough 10. Each limiting plate 24 is provided with a long strip-shaped mounting groove. Screws or bolts pass through the mounting groove to install the limiting plate 24 on the frame 1. The distance between the two limiting plates 24 can be adjusted through the long strip-shaped mounting groove, thereby adjusting the size of the conveying trough 10 to meet the conveying needs of workpieces 22 of different sizes, improve the applicability, and reduce processing costs.

[0031] Furthermore, the pressure plate 11 is detachably mounted on one of the limiting plates 24 via a connecting plate. The pressure plate 11 is provided with a vertically arranged elongated groove. Screws or bolts pass through the elongated groove to mount the pressure plate 11 onto the connecting plate. The height of the pressure plate 11 can be adjusted via the elongated groove to meet the usage requirements of workpieces 22 of different sizes, thereby increasing the applicability and reducing processing costs.

[0032] The chamfering mechanism includes two grinding wheels 12, one on each side of the conveying groove 10. The grinding wheels 12 are connected to an existing drive device (not shown in the figure) and rotate continuously under the drive of the drive device. The grinding wheels 12 are used to chamfer the workpiece 22. By simultaneously chamfering both sides of the workpiece 22 with the two grinding wheels 12, the chamfering efficiency is improved. The pushing mechanism continuously pushes the workpiece 22 into the conveying groove 10. Multiple workpieces 22 move along the pushing groove 10. When a workpiece 22 moves to the grinding wheel 12, the grinding wheel 12 chamfers the workpiece 22, improving the chamfering efficiency. Due to the squeezing action between adjacent workpieces 22, the shaking of the workpiece 22 during grinding is reduced, thus ensuring that the chamfering dimensions are within the design tolerance range and guaranteeing the chamfering quality.

[0033] In this embodiment, the third conveying mechanism includes a support plate and a guide cover 13 disposed on the support plate. The guide cover 13 and the support plate cooperate to form a "U" shape, which guides the workpiece 22, keeps the chamfered workpiece 22 upright, and prevents individual workpieces 22 from tilting upward, thus ensuring the normal conveying of the workpiece 22.

[0034] Furthermore, the guide cover 13 includes two guide plates, which are detachably mounted on the frame 1. The guide plates are Z-shaped and have elongated fixing grooves. Screws or bolts pass through the fixing grooves to install the guide plates on the frame 1. By adjusting the installation position of the two guide plates, the distance between the two guide plates can be adjusted to meet the usage requirements of workpieces 22 of different sizes, improve the applicability, and reduce processing costs.

[0035] In this embodiment, the material distribution mechanism includes a second drive cylinder 14 and a second sensor 16. The output end of the second drive cylinder 14 is equipped with a material distribution plate 15, which is driven to move. The direction of movement of the material distribution plate 15 is perpendicular to the discharge direction of the third conveying mechanism. The second sensor 16 is used to detect the workpiece 22 and transmit the signal to the second drive cylinder 14. The second sensor 16 is a proximity sensor. When the second sensor 16 detects the workpiece 22, it transmits the signal to the second drive cylinder 14, which drives the material distribution plate 15 to move. The material distribution plate 15 pushes the workpiece 22 from the side, pushing the workpiece 22 one by one to the flipping mechanism, thereby distributing multiple workpieces 22 and ensuring that the workpieces 22 are conveyed to the flipping mechanism one by one, avoiding the accumulation of workpieces 22.

[0036] In this embodiment, the flipping mechanism includes a third flipping plate 17, a fourth flipping plate 18, and a second base plate 19. The third flipping plate 17 is located on one side of the second base plate 19, and the fourth flipping plate 18 is located on the other side of the second base plate 19. The third flipping plate 17 and the fourth flipping plate 18 gradually flip from a vertical state to a horizontal state along the conveying direction of the workpiece 22. Under the action of the third flipping plate 17 and the fourth flipping plate 18, the workpiece 22 is flipped from a vertical state to a horizontal state. Since the material distribution plate 15 continuously pushes the workpiece 22 to the flipping mechanism, the subsequent workpiece 22 pushes the preceding workpiece 22 to move continuously. During the movement, the workpiece 22 gradually flips to a horizontal state, ensuring the normal conveying of the workpiece 22.

[0037] Furthermore, the flip plate 3 17 and the flip plate 4 18 are detachably mounted on the frame 1, and the distance between them can be adjusted by adjusting the mounting position of the flip plate 3 17 and the flip plate 4 18, thereby meeting the usage requirements of workpieces 22 of different sizes and reducing processing costs.

[0038] The automatic chamfering equipment also includes a material feeding and conveying mechanism located at the outlet of the flipping mechanism. The material feeding and conveying mechanism includes a second drive motor 20 and a second conveyor belt 21. The output end of the second drive motor 20 is connected to the second conveyor belt 21 for transmission. When the second drive motor 20 is working, it drives the second conveyor belt 21 to rotate, thereby automatically conveying the workpiece 22 output from the flipping mechanism to the next process, improving the overall processing efficiency of the workpiece 22.

[0039] Furthermore, in order to ensure the normal transport of workpiece 22, the parts in contact with workpiece 22 are all made of non-magnetic materials, such as plastic or aluminum.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
