Description

[0002] The surface grinding process of square components plays a key role in the production of electronic components, especially in the field of high precision requirements. In order to meet these high-precision manufacturing requirements, grinding equipment must have the ability to accurately control grinding depth, surface quality and production efficiency. Existing grinding machine equipment generally uses grinding wheels for surface treatment of materials, but during the grinding process, the wear of the grinding wheel itself will affect the grinding accuracy, resulting in inconsistent dimensions and fluctuations in product quality. In addition, the grinding wheel will generate heat during high-speed rotation and grinding, which can easily have a negative impact on components, and thermal deformation of the grinding wheel will also cause a decrease in grinding accuracy. Therefore, how to ensure the high precision and consistency of the grinding process and effectively control the wear of the grinding stone has become a technical problem to improve production efficiency and reduce costs.

[0007] The flattening plane is arranged at one end of the fine grinding part facing the jig, one end of the cutting bevel is connected to the coarse grinding part, and the other end is passed through the medium grinding part and connected to the fine grinding part;

[0008] The distance between one end of the coarse grinding part away from the fine grinding part and the feeding guide rail is greater than the height of the fixture, and the coarse grinding part and the feeding guide rail are clamped together to form a feeding port.

[0009] In one embodiment of the present application, a discharge port is provided at one end of the fine grinding portion away from the feed port, and the distance between the discharge port and the loading guide rail gradually increases along the transmission direction of the jig.

[0010] In one embodiment of the present application, the coarse grinding part is detachably connected to the middle grinding part, the middle grinding part is detachably connected to the fine grinding part, and the coarse grinding part, middle grinding part and fine grinding part move synchronously relative to the grinding guide rail.

[0011] In one embodiment of the present application, the machine table is provided with a fixed material stop structure relative to the grinding structure, the fixed material stop structure is parallel to the feeding guide rail, the fixed material stop structure and the grinding structure are sequentially arranged along the transmission direction of the jig, and the fixed material stop structure is connected to the rough grinding part;

[0019] By adopting the above technical solution, the present invention has the following advantages:

[0020] 1. A feeding guide rail is arranged on the machine along the extension direction of the machine, which is used to make the jig carrying the material slide in a straight line. The mounting frame can suspend the grinding structure so that the grinding structure can reciprocate in the direction perpendicular to the jig. The mounting frame ensures the stability of the position of the grinding structure, and can ensure that the grinding efficiency and grinding accuracy meet the requirements. When the jig carries the material to be ground and pushes it toward the grinding structure, the grinding structure will press on the material while grinding, so that the material is placed stably, which can effectively ensure the grinding effect.

[0021] 2. The grinding structure is provided with a cutting bevel and a leveling plane. The height of the leveling plane is the height when the material meets the standard. After the material is arranged in the fixture, it enters the cutting bevel and is gradually ground along the cutting bevel after contacting the grinding structure. When the material is gradually ground and contacts the wear part, the material is ground to a height that meets the requirements and gradually enters the leveling plane. When the material enters the leveling plane, the grinding structure is still pressed on the top of the material. At this time, the height of the material will not be worn anymore, but the top of the material that cannot shake can be finely trimmed at the micron level by relying on the leveling plane to improve the product quality. The grinding structure under this structure will not be unusable due to wear, and as the grinding structure is used for a long time As the lengthening of the grinding wheel increases, the slope of the cutting bevel generally will not change significantly, but the leveling plane will gradually decrease, and the wear portion will move with the cutting bevel toward the other end of the leveling plane. Except for the smaller area of ​​the leveling plane, the overall structure of the grinding structure will not change with the change of usage time. As long as the area of ​​the leveling plane is not zero, the grinding structure of the present application will be able to work normally and stably, which can effectively improve the life of the machine body, and there is no need to frequently replace the grinding structure. The grinding structure itself will not lead to a decline in product quality due to wear, which can effectively improve the user experience, and the grinding structure installed on the mounting frame can be replaced very conveniently, which can improve the maintenance efficiency of the equipment.

[0022] 3. The material is arranged in the jig before entering the grinding, and can be arranged in multiple rows, with excellent grinding efficiency. The grinding structure is slidably connected to the mounting frame, and the driving structure installed on one side of the mounting frame can drive the grinding structure to reciprocate in a direction perpendicular to the moving direction of the jig to grind the surface of the material. The linear speed of grinding will decrease under this power structure, and the grinding structure squeezes the material, resulting in a relatively low feeding speed of the material, so that for a single piece of material, its processing rate is not high, but the jig can be provided with multiple grinding stations, and the distance from the cutting bevel to the flattening plane of the grinding structure is much greater than the length of the material, so that the grinding structure can simultaneously process a large number of materials in different processing states, so that the grinding efficiency is very high, and compared with grinding wheel grinding, the grinding structure of the present application has a low linear speed, so that the grinding heat is small, and the low heat makes the grinding structure less wear, and after testing, using a diamond-coated grinding stone, when processing small square components such as inductors, the life span exceeds one month and no trimming is required in the middle, and the above structure can efficiently and stably improve the accuracy and efficiency of grinding small components.

[0030] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] Reference Figures 1 to 4 To achieve the above-mentioned purpose, the present invention proposes a grinding mechanism for square components, including a machine table 1, a feeding guide rail 11 is provided on the machine table 1, a jig 7 is slidably connected to the feeding guide rail 11, a mounting frame is provided at one end of the machine table 1 facing the feeding guide rail 11, a grinding guide rail is provided on the mounting frame relative to the feeding guide rail 11, a grinding structure 2 is slidably connected to the grinding guide rail, and the transmission direction of the grinding guide rail is perpendicular to the transmission direction of the feeding guide rail 11;

[0033] A cutting bevel 31 is provided on the bottom wall of one end of the grinding structure 2 toward the transmission direction of the jig 7, and a flattening plane 51 is provided on the other end. The distance between the cutting bevel 31 and the loading guide rail 11 gradually decreases along the transmission direction of the jig 7. The flattening plane 51 is parallel to the track of the jig 7. One end of the flattening plane 51 is connected to the cutting bevel 31, and a wear portion 32 is formed between the flattening plane 51 and the cutting bevel 31.

[0034] A loading guide rail 11 is provided on the machine table 1 along the extension direction of the machine table 1 for making the jig 7 carrying the material slide in a straight line direction. The mounting frame can suspend the grinding structure 2 so that the grinding structure 2 can reciprocate in the direction perpendicular to the jig 7. The mounting frame ensures the stability of the position of the grinding structure 2, and can ensure that the grinding efficiency and grinding accuracy meet the requirements. When the jig 7 carries the material to be ground and pushes it toward the grinding structure 2, the grinding structure 2 will be pressed on the material as a whole during grinding, so that the material is placed stably and the grinding effect can be effectively guaranteed.

[0035] The grinding structure 2 is provided with a cutting bevel 31 and a flattening plane 51. The height of the flattening plane 51 is the height of the material when it meets the standard. After the material is arranged in the fixture 7, it enters the cutting bevel 31 and is gradually ground along the cutting bevel 31 after contacting the grinding structure 2. When the material is gradually ground and contacts the wear portion 32, the material is ground to a height that meets the requirements and gradually enters the flattening plane 51. When the material enters the flattening plane 51, the grinding structure 2 is still pressed on the top of the material. At this time, the height of the material will not be worn anymore, but the flattening plane 51 can be used to perform micron-level finishing on the top of the material that cannot be shaken, so as to improve the product quality. The grinding structure 2 under this structure will not be unusable due to wear. As the grinding structure 2 is used As the usage time increases, the slope of the cutting bevel 31 generally will not change significantly, but the flattening plane 51 will gradually decrease, and the wear portion 32 will move together with the cutting bevel 31 toward the other end of the flattening plane 51. Except for the smaller area of ​​the flattening plane 51, the overall structure of the grinding structure 2 will not change with the change in usage time. As long as the area of ​​the flattening plane 51 is not zero, the grinding structure 2 of the present application will be able to work normally and stably, which can effectively improve the life of the machine body, and there is no need to frequently replace the grinding structure 2. The grinding structure 2 itself will not cause product quality to decline due to wear, which can effectively improve the user experience, and the grinding structure 2 installed on the mounting frame can be replaced very conveniently, which can improve the maintenance efficiency of the equipment.

[0036] The material is arranged in the jig 7 before entering the grinding, and can be arranged in multiple rows, with excellent grinding efficiency. The grinding structure 2 is slidably connected to the mounting frame, and the driving structure installed on one side of the mounting frame can drive the grinding structure 2 to reciprocate in a direction perpendicular to the moving direction of the jig 7 to grind the surface of the material. The linear speed of grinding will decrease under this power structure, and the grinding structure 2 squeezes the material, resulting in a relatively low feeding speed of the material, so that for a single piece of material, its processing rate is not high, but the jig 7 can be provided with multiple grinding stations 8, and the distance from the cutting bevel 31 of the grinding structure 2 to the flattening plane 51 is much greater than the length of the material, so that the grinding structure 2 can simultaneously process a large number of materials in different processing states, so that the grinding efficiency is very high, and compared with grinding wheel grinding, the grinding structure 2 of the present application has a low linear speed, so that the grinding heat is small, and the low heat makes the wear of the grinding structure 2 small, and after testing, using a diamond-coated grinding stone, when processing small square components such as inductors, the life span exceeds one month and no trimming is required in the middle, and the above structure can efficiently and stably improve the accuracy and efficiency of grinding small components.

[0037] Combined with reference Figure 1 to Figure 2The grinding structure 2 includes a coarse grinding part 3, a medium grinding part 4, and a fine grinding part 5, which are arranged in sequence along the transmission direction of the jig 7; a flattening plane 51 is arranged at one end of the fine grinding part 5 facing the jig 7, one end of the cutting bevel 31 is connected to the coarse grinding part 3, and the other end is passed through the medium grinding part 4 and connected to the fine grinding part 5; the distance between one end of the grinding part away from the fine grinding part 5 and the feeding guide rail 11 is greater than the height of the jig 7, and the coarse grinding part 3 and the feeding guide rail 11 are clamped to form a feeding port.

[0038] The grinding structure 2 includes a coarse grinding part 3, a medium grinding part 4, and a fine grinding part 5. The three grinding parts can be arranged in sequence and formed in one piece. The grinding structure 2 is generally a grinding stone, which can rely on the mounting frame to limit and guide the sliding, and the driving structure arranged on one side of the mounting frame is used to make the grinding stone reciprocate on the grinding guide rail. The flattening plane 51 is arranged on the fine grinding part 5. One end of the cutting bevel 31 is connected to the coarse grinding part 3, and the other end is connected to one end of the flattening plane 51, and a wear part 32 is formed. The height of the cutting bevel 31 gradually decreases from the coarse grinding part 3 to the fine grinding part 5. The coarse grinding part 3 is used for grinding. The burrs on the upper end of the grinding material are removed. The middle grinding part 4 is used to grind the material to make it thinner. The fine grinding part 5 accurately grinds the material through the flattening plane 51 to improve the quality of the material. The material must be lower than the feed port before grinding. The grinding structure 2 is provided with a trimming plane and a flattening plane 51. The material enters from the feed port after being arranged in the fixture 7 and is gradually ground along the cutting bevel 31 after contacting the grinding stone. This structure can ensure the grinding efficiency and improve the grinding accuracy. As long as the flattening plane 51 is not completely worn out, the grinding structure 2 can continue to work normally and can be effectively used in large-scale production and processing manufacturing industries.

[0039] Combined with reference Figure 1 to Figure 2 A discharge port 52 is provided at one end of the fine grinding portion 5 away from the feed port, and the distance between the discharge port 52 and the loading guide rail 11 gradually increases along the transmission direction of the fixture 7.

[0040] The setting of the discharge port 52 can release the material gradually. The discharge port 52 can protect the material while gradually releasing the material to prevent the material from flying away. The setting of the discharge port 52 can make the edges and corners of the grinding structure 2 smoother to avoid injuries to users.

[0041] Combined with reference Figure 1 The coarse grinding part 3 is detachably connected to the medium grinding part 4, and the medium grinding part 4 is detachably connected to the fine grinding part 5. The coarse grinding part 3, the medium grinding part 4, and the fine grinding part 5 move synchronously relative to the grinding guide rail.

[0042] The coarse, medium and fine parts of the grinding structure 2 can be a combined structure. Since the coarse grinding part 3 generally plays a guiding role, its service life can be much longer than that of the medium grinding part 4 and the fine grinding part 5. The detachable structure can reduce the equipment cost and facilitate the replacement of the grinding part, which can effectively improve the accuracy and efficiency of grinding small components.

[0043] Combined with reference Figure 1 The machine 1 is provided with a fixed material stop structure 6 relative to the grinding structure 2. The fixed material stop structure 6 is parallel to the feeding guide rail 11. The fixed material stop structure 6 and the grinding structure 2 are sequentially arranged along the transmission direction of the fixture 7. The fixed material stop structure 6 is connected to the rough grinding part 3.

[0044] The distance between one end of the coarse grinding portion 3 away from the fine grinding portion 5 and the feeding guide rail 11 is greater than the distance between the fixed material blocking structure 6 and the feeding guide rail 11 .

[0045] The fixed material retaining structure 6 is used to lower the material to be ground. The end of the rough grinding part 3 is higher than the fixed material retaining structure 6, so that the feed port can better and more stably limit and guide the jig 7 and the material. The fixed material retaining structure 6 can effectively improve the processing accuracy of components.

[0046] Combined with reference Figure 3 to Figure 4 A plurality of grinding stations 8 are arranged in an array on the fixture 7, materials are arranged on the grinding stations 8, the width of the grinding stations 8 is greater than the width of the materials, and air avoidance grooves 83 are arranged at the bottom corners of the grinding stations 8 relative to the materials.

[0047] A plurality of grinding stations 8 can be arranged on the jig 7, and the length of the jig 7 is generally much smaller than the length of the grinding structure 2, so that a large amount of material can be ground in the grinding structure 2 at the same time, so that even if the processing efficiency of a piece of material is not high, a large amount of simultaneous processing can effectively improve the processing efficiency, and the air avoidance groove 83 can effectively protect the bottom edges and corners of the material to prevent the structure that does not need to be ground from being ground. The width of the grinding station 8 is greater than the width of the material, so that the material will not be completely stuck during the initial grinding, and has a certain degree of mobility, which can avoid damage to the material structure and improve the grinding accuracy. The powder ground from the material can gradually fill in the air avoidance groove 83 and the gap between the material and the grinding station 8 when the material is shaken left and right. As the grinding becomes finer, the powder gradually fills the gap on both sides of the material and gradually presses against the material, so that the material will not shake. The material that will not shake can be ground more finely on the left and right of the grinding structure 2. The material is pressed by the powder filler, which can avoid damage to the edges and corners of the material and has a better protection effect on the material.

[0048] Combined with reference Figure 4The grinding station 8 is provided with a side retaining wall 81 and a supporting structure 82. One end of the air avoidance groove 83 is connected to the side retaining wall 81, and the other end is connected to the supporting structure 82. The air avoidance groove 83 surrounds the bottom edge of the material; the distance between the two side retaining walls 81 arranged opposite to each other is greater than the width of the material.

[0049] The side retaining wall 81 can limit the material. The setting of the side retaining wall 81 and the supporting structure 82 allows the edges and corners of the material to be suspended. As the distance between the material and the side retaining wall 81 changes, the powder can enter the air avoidance groove 83 through the gap, so that the material is gradually compressed. The above structure can effectively improve the accuracy and efficiency of grinding small components.

[0050] Combined with reference Figure 4 The grinding station 8 is provided with at least two supporting structures 82 , and an avoidance groove is provided between two adjacent supporting structures 82 .

[0051] The support structure 82 is two slender planes. This structure can move the material left and right. When the material is under the pressure of the upper grinding structure 2, the dust and dirt at the place where the bottom of the material contacts the support surface will fall to both sides. Because there are side baffles 81 and support platform structures on the grinding fixture 7, in the early stage of grinding, since the width of the grinding station 8 is larger than the width of the material, the material moves slightly left and right in the material trough, and the grinding dust falls into the gap of the side baffle 81. The gap keeps opening and closing, and the dust gathers more and more and is gradually compressed, eventually filling the gap, and the material cannot move. During subsequent fine-tuning, the grinding accuracy can be achieved because the product is firmly fixed.

[0052] Combined with reference Figure 3 to Figure 4 A plurality of first ash containing grooves 84 are arranged in an array on the fixture 7 , and the plurality of first ash containing grooves 84 are staggered with the grinding stations 8 , and the first ash containing grooves 84 are located between two adjacent grinding stations 8 .

[0053] There are multiple first ash troughs 84, and they are located between two adjacent grinding stations 8. They can be used to receive dust overflowing from the grinding station 8, keep the surface of the material clean, and prevent the dust from affecting the effect of further grinding of the material. The first ash trough 84 can collect most of the dust and make the dust distribution more even, which is convenient for subsequent dust cleaning and the operation of the cleaning jig 7, and can effectively improve the processing efficiency.

[0054] Combined with reference Figure 3 A second ash containing groove 9 is provided on the outer periphery of the jig 7 relative to the plurality of grinding stations 8 , and the second ash containing groove 9 surrounds the plurality of grinding stations 8 , and the depth of the second ash containing groove 9 is greater than the depth of the first ash containing groove 84 .

[0055] A second ash trough 9 is provided on the periphery of the jig 7 relative to the plurality of grinding stations 8. The second ash trough 9 is used to receive dust that overflows from the first ash trough 84 and that fails to be successfully received by the first ash trough 84. The second ash trough 9 is generally deeper than the first ash trough 84 and has a larger capacity. The second ash trough 9 surrounds the plurality of grinding stations 8 and the plurality of first ash troughs 84 to ensure that dust does not escape from the jig 7, which is beneficial for the subsequent cleaning of the jig 7 and the cleaning of the feeding guide rail 11, and facilitates the subsequent grinding process of the jig 7. Through the cooperation of the above structures, the accuracy and efficiency of grinding small components can be efficiently and stably improved.
