Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a surface grinding device. Background Technology

[0002] Surface grinding equipment can grind products on a fixture. During the loading process, the product is placed on the upper surface of the fixture. However, surface grinding equipment can usually only grind the product from below. Therefore, before processing the product, the fixture needs to be flipped so that the product is located below the fixture, allowing the surface grinding equipment to process the product. In the existing technology, the fixture is flipped manually, which is inefficient, and the product is prone to falling out of the fixture during the flipping process. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a surface grinding device that can automatically rotate the fixture and reduce the risk of the product falling off the fixture during the rotation process.

[0004] This utility model provides a flat grinding device, which includes a feeding mechanism, a flat grinding mechanism, a transfer mechanism, and a tilting mechanism. The feeding mechanism is equipped with a jig, which carries the product and exposes the surface of the product to be ground on the top side of the jig. The grinding mechanism is used to grind the surface of the product. The transfer mechanism is used to transfer the jig. The flipping mechanism includes a flipping drive, a flipping platform, a first component, and a second component. The flipping drive is connected to the flipping platform. The flipping platform has a through hole with a first opening and a second opening. The first component is located at the first opening, and the second component is located at the second opening. When the transfer mechanism transfers the jig to the flipping platform, the first component opens the first opening, and the second component closes the second opening, allowing the jig to enter the through hole from the first opening and be supported by the second component. When the flipping drive drives the flipping platform to rotate, the first component closes the first opening, and the second component closes the second opening to prevent the jig from leaving the through hole. After the flipping platform has flipped, the jig is supported by the first component, and the surface of the product to be ground on the jig is exposed on the bottom side. The second component opens the second opening, allowing the transfer mechanism to transfer the jig in the through hole to the grinding mechanism.

[0005] The surface grinding equipment provided by this utility model has at least the following beneficial effects:

[0006] On the one hand, the transfer mechanism can transfer the fixture to the through hole on the flipping platform. The flipping platform can drive the fixture inside the through hole to flip, exposing the surface of the product to be ground on the fixture to the bottom, thereby realizing automatic fixture flipping. On the other hand, the first component can close the first opening, and the second component can close the second opening. The flipping platform, the first component, and the second component work together to enclose the fixture and the product, thereby reducing the risk of the product falling out of the fixture.

[0007] In one embodiment of this implementation, a first plane and a first axis are defined. The rotation axis of the flipping platform is the first axis, which is located in the first plane.

[0009] In one embodiment of this implementation, the first limiting member can move relative to the flipping platform along a first direction, the first direction being perpendicular to the first axis direction, and the sum of the dimensions of the two first limiting members in the first direction is half the dimension of the flipping platform in the first direction.

[0010] In one embodiment of this implementation, the second component includes two second limiting members. The projections of the two second limiting members on the first plane are symmetrically distributed around the first axis. The second limiting members are movably connected to the flipping platform. The two second limiting members can move to the second opening to restrict the fixture from leaving the through hole.

[0011] In one embodiment of this implementation, the flipping platform is provided with multiple through holes to accommodate multiple jigs.

[0012] In one embodiment of this implementation, a plurality of through holes are arranged at intervals along a second direction.

The spacing adjustment assembly is connected to the plurality of grippers and can adjust the spacing between the plurality of grippers to adjust the spacing between the plurality of fixtures connected to the grippers.

[0014] In one embodiment of this implementation, the flat grinding equipment includes two flat grinding mechanisms arranged at intervals, the two flat grinding mechanisms, the feeding mechanism and the turning mechanism are arranged in a straight line, the turning mechanism and the feeding mechanism are located between the two flat grinding mechanisms, and the transfer drive assembly can drive the gripper to move in a straight line from one of the flat grinding mechanisms to the other flat grinding mechanism.

[0015] In one embodiment of this implementation, the surface grinding equipment further includes a first transfer component, a second transfer component, a conveying component, and multiple variable-pitch sliders. The first transfer component is adjacent to the material receiving position, on which multiple products are placed. The variable-pitch sliders have fixed grooves.

[0038] Please see Figures 1 to 6 , Figure 8 , Figure 1 This is a three-dimensional structural schematic diagram of a surface grinding device 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 A top view of the surface grinding equipment 100; Figure 3 yes Figure 1 A schematic diagram of the flipping mechanism 40; Figure 4 yes Figure 3 A schematic diagram of the flipping mechanism 40 from another perspective; Figure 5 yes Figure 3 A schematic diagram of the structure of the flipping platform 42; Figure 6 yes Figure 1 A schematic diagram of the transfer mechanism 30; Figure 8 yes Figure 1A schematic diagram of the structure of the feeding mechanism 10. This utility model provides a surface grinding device 100, which includes a feeding mechanism 10, a surface grinding mechanism 20, a transfer mechanism 30, and a tilting mechanism 40. The feeding mechanism 10 is equipped with a fixture 200, which carries a product 300 and exposes the surface of the product 300 to be ground on the top side of the fixture 200. The surface grinding mechanism 20 is used to grind the surface of the product 300. The transfer mechanism 30 is used to transfer the fixture 200. The tilting mechanism 40 includes a tilting drive 41, a tilting platform 42, a first component 43, and a second component 44. The tilting drive 41 is connected to the tilting platform 42. The tilting platform 42 has a through hole 421 with opposing first openings 4211 and second openings 4212. The first component 43 is located at the first opening 4211, and the second component 44 is located at the second opening 4212. When the transfer mechanism 30 transfers the fixture 200 to the tilting platform... When the platform 42 is rotated, the first component 43 opens the first opening 4211 and the second component 44 closes the second opening 4212, allowing the fixture 200 to enter the through hole 421 from the first opening 4211 and be supported by the second component 44. When the flipping drive 41 drives the flipping platform 42 to rotate, the first component 43 closes the first opening 4211 and the second component 44 closes the second opening 4212 to restrict the fixture 200 from leaving the through hole 421. After the flipping platform 42 has flipped, the fixture 200 is supported by the first component 43, and the surface of the product 300 on the fixture 200 is exposed to the bottom. The second component 44 opens the second opening 4212, allowing the transfer mechanism 30 to transfer the fixture 200 in the through hole 421 to the surface grinding mechanism 20.

[0039] Specifically, the surface grinding equipment 100 grinds the product 300 using a grinding disc. The grinding disc can grind the product 300 located above it. A first component 43 is movably connected to a tilting platform 42, and a second component 44 is movably connected to the tilting platform 42. The tilting platform 42 is flat, and a through hole 421 penetrates both surfaces 422 of the tilting platform 42, with the axis of the through hole 421 perpendicular to the surfaces 422 of the tilting platform 42. The dimensions of the first opening 4211 and the second opening 4212 are adapted to the dimensions of the fixture 200, allowing the fixture 200 to enter and exit the through hole 421 through the first opening 4211 and the second opening 4212. The first component 43 and the second component 44 can move along the two opposite surfaces 422 of the tilting platform 42 towards the through hole 421, respectively, to reach... When the first component 43 moves to one side of the through hole 421 along the axial direction of the through hole 421, it covers the first opening 4211 to close the first opening 4211. When the second component 44 moves to one side of the through hole 421 along the axial direction of the through hole 421, it covers part of the second opening 4212 to close the second opening 4212. The first component 43 and the second component 44 can move away from the through hole 421 along the two opposite plates 422 of the flipping platform 42 to open the first opening 4211 and the second opening 4212. The flipping drive 41 is connected to the flipping platform 42 by a transmission belt. The flipping drive 41 can drive the flipping platform 42 to rotate around an axis parallel to the horizontal plane.

[0040] In this embodiment, the flipping platform 42 first flips so that the plate surface 422 on which the first component 43 is installed faces upward. The second component 44 moves to below the through hole 421. The transfer mechanism 30 inserts the fixture 200 from above the flipping platform 42 into the through hole 421. The second component 44 generates an upward supporting force on the fixture 200. Then, the first component 43 moves above the through hole 421 and covers the first opening 4211. The flipping platform 42 rotates 180 degrees around an axis parallel to the horizontal plane so that the plate surface 422 on which the second component 44 is installed faces upward. The first component 43 generates an upward supporting force on the fixture 200, and the surface of the product 300 to be ground faces downward. At this time, the fixture 200 has completed its flipping. Subsequently, the second component 44 moves along the plate surface 422 away from the second opening 4212, causing the second opening 4212 to open, so that the transfer mechanism 30 can transfer the fixture 200 to the surface grinding mechanism 20 through the second opening 4212. The cycle of the above process constitutes the working process of the flipping mechanism 40. It should be noted that in the through hole 421, the product 300 is located on the side of the fixture 200 opposite to the first opening 4211.

[0041] Understandably, the first component 43 covers the first opening 4211, which can restrict the product 300 from moving out of the first opening 4211, thereby reducing the risk of the product 300 falling off the fixture 200.

[0042] The surface grinding equipment 100 of this utility model has two aspects. First, the transfer mechanism 30 can transfer the fixture 200 to the through hole 421 on the flipping platform 42. The flipping platform 42 can drive the fixture 200 in the through hole 421 to flip, so that the surface of the product 300 to be ground on the fixture 200 is exposed to the bottom side, thereby realizing automatic flipping of the fixture 200. Second, the first component 43 can close the first opening 4211, and the second component 44 can close the second opening 4212. The flipping platform 42, the first component 43, and the second component 44 work together to enclose the fixture 200 and the product 300, thereby reducing the risk of the product 300 falling out of the fixture 200.

[0043] Please see Figures 3 to 5 , Figure 3 yes Figure 1 A schematic diagram of the flipping mechanism 40; Figure 4 yes Figure 3 A schematic diagram of the flipping mechanism 40 from another perspective; Figure 5 yes Figure 3 A schematic diagram of the structure of the flipping platform 42; in one embodiment of this implementation, a first plane and a first axis 400 are defined, the rotation axis of the flipping platform 42 is the first axis 400, the first axis 400 is located in the first plane, and the geometric center of the projection of the flipping platform 42 in the first plane is located on the first axis 400.

[0044] Specifically, the flipping platform 42 is a generally rectangular plate. The first plane is parallel to the plate surface 422 of the flipping platform 42. The projection of the flipping platform 42 onto the first plane is generally rectangular, with two parallel long sides. The first axis 400 is parallel to the long sides of the rectangular projection, and the distance between the first axis 400 and the two long sides is equal. The two parts of the flipping platform 42 located on either side of the first axis 400 have equal dimensions in the direction perpendicular to the first axis 400.

[0045] It is understandable that the rotating platform 42 sweeps over a cylindrical area during its rotation. The rotating platform 42 rotates around the first axis 400, and the geometric center of the projection of the rotating platform 42 in the first plane is located on the first axis 400. This can reduce the radius of the cylindrical area swept by the rotating platform 42, thereby reducing the space required to ensure the normal operation of the rotating platform 42, which is beneficial to reducing the size of the surface grinding equipment 100.

[0046] Please see Figure 3In one embodiment of this implementation, the first component 43 includes two first limiting members 431. The projections of the two first limiting members 431 on the first plane are symmetrically distributed with the first axis 400 as the center. The first limiting members 431 are movably connected to the flipping platform 42. The two first limiting members 431 can move to the first opening 4211 to restrict the fixture 200 from leaving the through hole 421.

[0047] Specifically, a guide rail is installed on the flipping platform 42, and the first limiting member 431 slides with the guide rail. The extension direction of the guide rail is parallel to the plate surface 422, and the first limiting member 431 can move along the plate surface 422. The distance between the two first limiting members 431 and the rotation axis of the flipping platform 42 is equal. In the direction perpendicular to the first axis 400, the two first limiting members 431 are located on both sides of the first axis 400. The first component 43 also includes two first limiting cylinders 432, which are connected one-to-one with the two first limiting members 431. The driving directions of the two first limiting cylinders 432 are opposite, and the first limiting cylinders 432 can drive the first limiting members 431 to move.

[0048] Understandably, the two first limiting members 431 can move in opposite directions. They can approach the through hole 421 from both sides to cover a portion of the first opening 4211. They can also move in opposite directions to open the first opening 4211. When the size of the first opening 4211 is large, setting the first component 43 as two first limiting members 431 moving in opposite directions, compared to the scheme where the first component 43 moves in one direction to open and close the first opening 4211, helps reduce the volume of the cylindrical space swept by the entire structure of the rotating platform 42 and the first component 43 during rotation, thus reducing the size of the surface grinding equipment 100.

[0049] Please see Figure 3 In one embodiment of this implementation, the first limiting member 431 can move relative to the flipping platform 42 along a first direction, the first direction being perpendicular to the first axis 400, and the sum of the dimensions of the two first limiting members 431 in the first direction is half the dimension of the flipping platform 42 in the first direction.

[0050] Specifically, the first direction is the Y direction. The movable distance of the first limiting member 431 relative to the flipping platform 42 in the Y direction is equal to the dimension of the first limiting member 431 in the Y direction. When the first opening 4211 is closed, the two first limiting members 431 abut against each other. This arrangement can reduce the radius of the cylindrical space swept by the flipping platform 42 and the first component 43, while increasing the coverage area of ​​the two first limiting members 431 on the flipping platform 42.

[0051] Please see Figures 3 to 4 In one embodiment of this implementation, the second component 44 includes two second limiting members 441. The projections of the two second limiting members 441 on the first plane are symmetrically distributed with the first axis 400 as the center. The second limiting members 441 are movably connected to the flipping platform 42. The two second limiting members 441 can move to the second opening 4212 to restrict the fixture 200 from leaving the through hole 421.

[0052] Specifically, a guide rail is installed on the flipping platform 42, and the second limiting member 441 slides with the guide rail. The extension direction of the guide rail is parallel to the plate surface 422. The second limiting member 441 moves on the plate surface 422 in a direction perpendicular to the first axis 400. The distance between the two second limiting members 441 and the first axis 400 is equal. In the direction perpendicular to the first axis 400, the two second limiting members 441 are located on both sides of the first axis 400. The second component 44 also includes two second limiting cylinders 442, which are connected one-to-one with the two second limiting members 441. The driving directions of the two second limiting cylinders 442 are opposite, and the second limiting cylinders 442 can drive the second limiting members 441 to move.

[0053] Understandably, the two second limiting members 441 can move in opposite directions. They can approach the through hole 421 from both sides along a direction perpendicular to the first axis 400, respectively, to cover a portion of the second opening 4212. They can also move in opposite directions to open the second opening 4212. When the size of the second opening 4212 is large, setting the first component 43 as two second limiting members 441 moving in opposite directions, compared to the scheme where the first component 43 moves in one direction to open and close the second opening 4212, helps reduce the volume of the cylindrical space swept by the entire structure of the tilting platform 42 and the first component 43 during the rotation of the tilting platform 42, thereby reducing the volume of the surface grinding equipment 100.

[0054] Please see Figures 3 to 5 In one embodiment of this implementation, the flipping platform 42 is provided with a plurality of through holes 421 to accommodate a plurality of fixtures 200.

[0055] Specifically, multiple through holes 421 are arranged at intervals on the flipping platform 42. It can be understood that by opening multiple through holes 421 on the flipping platform 42, the flipping platform 42 can flip multiple fixtures 200 at the same time, which is beneficial to improving the efficiency of the surface grinding equipment 100.

[0056] Please see Figures 1 to 3 , Figure 8 and Figure 9 , Figure 8 yes Figure 1 A schematic diagram of the feeding mechanism 10; Figure 9 yes Figure 8 A schematic diagram of the positioning component 12 is shown. In one embodiment of this implementation, a plurality of through holes 421 are arranged at intervals along a second direction. The feeding mechanism 10 includes a bearing component 11 and a plurality of positioning components 12. A plurality of fixtures 200 are arranged at intervals along the second direction on the bearing component 11. The plurality of positioning components 12 are arranged at intervals along the second direction on the bearing component 11. The positioning components 12 can abut against the fixtures 200 on the bearing component 11 and are used to adapt the spacing between two adjacent fixtures 200 on the bearing component 11 to the spacing between two adjacent through holes 421.

[0057] Specifically, the second direction is parallel to the X direction. The positioning component 12 includes a positioning cylinder 121 and a positioning block 122. The piston rod of the positioning cylinder 121 is connected to the positioning block 122. The fixture 200 is cylindrical. The positioning block 122 is provided with an arc surface 1221 that matches the radius of the outer circumference of the fixture 200. The positioning cylinder 121 can drive the positioning block 122 to approach the fixture 200 so that the arc surface 1221 on the positioning block 122 abuts against the outer circumference of the fixture 200.

[0058] It is understandable that the spacing between two adjacent positioning blocks 122 is adapted to the spacing between two adjacent through holes 421. The arc surface 1221 on the positioning block 122 can provide guidance for the fixture 200. During the process of the positioning cylinder 121 driving close to the fixture 200, the positioning block 122 can correct the position of the fixture 200 so that the spacing between two adjacent fixtures 200 on the bearing assembly 11 is adapted to the spacing between two adjacent through holes 421. This setting can facilitate the process of the transfer mechanism 30 moving multiple fixtures 200 into the through holes 421.

[0059] Please see Figure 1 , Figures 6 to 7 , Figure 6 yes Figure 1 A schematic diagram of the transfer mechanism 30. Figure 7 yes Figure 6 A schematic diagram of the structure of the spacing adjustment component 32 and the gripper 33. In one embodiment of this implementation, the transfer mechanism 30 includes a transfer drive component 31, a spacing adjustment component 32, and a plurality of grippers 33. The grippers 33 are used to connect the fixture 200. The transfer drive component 31 is connected to the plurality of grippers 33 and can drive the grippers 33 to move so as to move the fixture 200 in the through hole 421 to the surface grinding mechanism 20. The spacing adjustment component 32 is connected to the plurality of grippers 33 and can adjust the spacing of the plurality of grippers 33 so as to adjust the spacing of the plurality of fixtures 200 connected to the grippers 33.

[0060] Specifically, multiple spacing adjustment components 32 are provided. Multiple spacing adjustment components 32 and multiple gripping elements 33 are all set on the drive end of the transfer drive component 31. Multiple spacing adjustment components 32 and multiple gripping elements 33 are connected one-to-one. The transfer drive component 31 is a motor. The driving direction of the transfer drive component 31 is along the Y direction. The driving direction of the spacing adjustment component 32 is along the X direction. The spacing adjustment component 32 includes a motor and a gear. The motor is connected to the gear and to the gripping element 33. The motor can drive the gear to rotate. The transfer mechanism 30 also includes a rack (not shown) extending along the X direction. The gear meshes with the rack. When the gear rotates, the gear moves along the rack in the X direction and drives the gripping element 33 to move in the X direction.

[0061] Understandably, multiple spacing adjustment components 32 can drive multiple grippers 33 to move relative to each other in the X direction, thereby changing the spacing between two adjacent grippers 33. The surface grinding mechanism 20 has multiple surface grinding stations, which can perform surface grinding on the fixtures 200 at the surface grinding stations. The multiple surface grinding stations are not collinear. After the grippers 33 grip the multiple fixtures 200 arranged in a straight line on the flipping platform 42, the transfer drive component 31 and the spacing adjustment component 32 work together to sequentially drive the multiple fixtures 200 to align with the corresponding surface grinding stations and enter the surface grinding stations.

[0062] Please see Figure 1 and Figure 2 In one embodiment of this implementation, the flat grinding equipment 100 includes two flat grinding mechanisms 20 arranged at intervals. The two flat grinding mechanisms 20, the feeding mechanism 10 and the flipping mechanism 40 are arranged in a straight line. The flipping mechanism 40 and the feeding mechanism 10 are located between the two flat grinding mechanisms 20. The transfer drive assembly 31 can drive the gripper 33 to move in a straight line from one of the flat grinding mechanisms 20 to the other flat grinding mechanism 20.

[0063] Specifically, the two surface grinding mechanisms 20 are arranged along the Y direction, and the transfer drive assembly 31 can drive the gripper 33 to move along the Y direction to transfer the fixture 200 in the through hole 421 to the two surface grinding mechanisms 20 respectively. It can be understood that the two surface grinding mechanisms 20 can simultaneously perform grinding on the products 300 on multiple fixtures 200, which is beneficial to improving the processing efficiency of the surface grinding equipment 100.

[0064] Please see Figures 10 to 13 , Figure 10 yes Figure 1 A schematic diagram of the structure of the conveying component 53, the first transfer component 51, and the second transfer component 52; Figure 11 yes Figure 10 Top view of the conveyor assembly 53; Figure 12 yes Figure 10 A top view of the variable pitch slider 54, the first transfer component 51, and the second transfer component 52; Figure 13 yes Figure 12 A schematic diagram of the structure of the variable pitch slider 54. In one embodiment of this implementation, the surface grinding equipment 100 further includes a first transfer component 51, a second transfer component 52, a conveying component 53, and multiple variable pitch sliders 54. The first transfer component 51 is adjacent to the material receiving position, on which multiple products 300 are placed. The variable pitch sliders 54 are provided with fixed grooves 541. The first transfer component 51 is used to transfer the products 300 on the material receiving position to the fixed grooves 541. The multiple variable pitch sliders 54 are movably connected to each other and can move relative to each other to change the spacing between the products 300 on adjacent variable pitch sliders 54. The variable pitch sliders 54 are used to make the spacing between the multiple products 300 meet the expectation. The second transfer component 52 is used to transfer the products 300 on the variable pitch sliders 54 with the expected spacing to the fixture 200 on the material receiving position. One end of the conveying component 53 is located at the material receiving position, and the other end extends to the feeding mechanism 10. The conveying component 53 is used to convey the fixture 200 on the material receiving position to the feeding mechanism 10.

[0065] Specifically, the fixture 200 has thirty-six receiving slots, which can accommodate products 300 and are used to restrict the movement of products 300 relative to the fixture 200. The multiple receiving slots on the fixture 200 are divided into four groups of nine. The nine receiving slots in one group are arranged in a matrix of three rows and three columns, and the four groups of receiving slots are arranged in a matrix of two rows and two columns. A material tray 500 is placed on the material receiving position, and thirty-six products 300 are placed on the material tray 500, arranged in a matrix of six rows and six columns. The variable pitch slider 54 is provided with nine fixed slots 541, which are arranged in a matrix of three rows and three columns. There are four variable pitch sliders 54, which slide and cooperate with four intersecting guide rails respectively. When the four variable pitch sliders 54 are relatively close, the thirty-six fixed slots 541 on the four variable pitch sliders 54 form a six-row, six-column matrix that matches the multiple products 300 on the tray 500. When the four variable pitch sliders 54 are relatively far apart, the fixed slots 541 on the four variable pitch sliders 54 are divided into four groups of nine, and the four groups of fixed slots 541 form a two-row, two-column matrix that matches the receiving slots on the fixture 200. The conveying assembly 53 includes a conveying surface extending along the Y direction. The conveying assembly 53 can drive the fixture 200 on the conveying surface to move along the Y direction to convey the fixture 200 from the loading position to one side of the feeding mechanism 10 along the X direction. The conveying assembly 53 is provided with a reversing assembly 55. The reversing assembly 55 can move relative to the conveying surface along the Z direction to approach or move away from the fixture 200 on the conveying surface. When the reversing assembly 55 abuts against the fixture 200, it can drive the fixture 200 to move along the X direction to transfer the fixture 200 on the conveying surface to the feeding mechanism 10.

[0066] Understandably, before loading the fixture 200, the four variable-pitch sliders 54 approach each other, and the first transfer component 51 transfers the products 300 on the tray 500 to the fixed slot 541. Subsequently, the four variable-pitch sliders 54 move away from each other, causing the multiple products 300 in the fixed slot 541 to be divided into four groups, so that the four groups of products 300 form a two-row, two-column matrix that matches the four sets of receiving slots on the fixture 200. Then, the second transfer component 52 transfers the products 300 in the fixed slot 541 to the receiving slots according to the existing arrangement, thus completing the loading of the fixture 200. This setup, on the one hand, enables automatic loading, which is beneficial to improving production efficiency; on the other hand, it allows for adjustment of the arrangement of multiple products 300 on the tray 500 to adapt to the fixture 200, which is beneficial to improving the adaptability of the surface grinding equipment 100.
