DETAILED DESCRIPTION

[0017] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0018] like Figures 1 to 3As shown, a high-efficiency grinder for workpieces of the present application comprises: a workbench 1111, on which a conveyor platform 12 is provided for conveying workpieces. The conveyor platform 12 is provided with: a loading port 122 and a unloading port 126, between which are provided three stations, namely, a first grinding station 123, a second detection station 124, and a third grinding station 125, and at the same time, a position detection sensor 127 is provided on the conveyor platform 12 corresponding to the loading port 122, the unloading port 126 and the three stations, so as to sense the position arrival of the workpiece through the position detection sensor 127. Transfer components are provided below the conveyor 12, between the loading port 122 and the first grinding station 123, between the first grinding station 123 and the second inspection station 124, between the second inspection station 124 and the third grinding station 125, and between the third grinding station 125 and the unloading port 126, for transferring workpieces. A first grinding component is installed above the conveyor 12, through which the workpiece on the first grinding station 123 can be polished, a second inspection component is installed above the second inspection station 124 for image inspection of the polished surface of the workpiece, and a third grinding component is installed above the third grinding station 125, through which the unqualified parts of the workpiece can be re-polished, which can effectively improve the polishing accuracy of the workpiece, and evenly distribute re-polishing by image inspection can ensure the consistency of the polishing state of the workpiece, and the product quality is more uniform. During installation, a clamping cylinder 33 is arranged above the three workstations, and a clamping block 34 is provided at the end of the cylinder rod of the clamping cylinder 33 for clamping the workpieces on the multiple workstations, thereby ensuring the stability of the workpiece grinding state.

[0019] Specifically, a guide plate 13 is provided below the conveying platform 12, a slide plate 14 is slidably provided above the guide plate 13, and a driving cylinder 15 for driving the slide plate 14 to slide is installed at one end of the guide plate 13. A lifting cylinder 16 is installed above the slide plate 14, and a lifting plate 17 is installed at the lifting end of the lifting cylinder 16. A transfer screw 18 and a transfer motor 19 are rotatably installed above the lifting plate 17, and the transfer motor 19 drives the transfer screw 18 to rotate. The above-mentioned transfer assembly includes: a transfer plate 20 and a fixed baffle 21, the transfer plate 20 is threadedly sleeved on the outer periphery of the transfer screw 18 to be threadedly driven by the transfer screw 18, and performs linear motion to push the workpiece to the next station, and the fixed baffle 21 is sleeved on the outer periphery of the transfer screw 18 and fixed to the lifting plate 17, so as to receive the workpiece pushed by the transfer plate 20 and stop the workpiece at the designated grinding position. The conveying platform 12 is formed with a through slot 121 in the extending direction thereof, and the through slot 121 is used for the transfer plate 20 and the fixed baffle plate 21 to extend to push the workpiece and block the movement of the workpiece.

[0020] That is to say, when the grinder is running, after the workpiece is placed at the loading port 122 by an external manipulator, the driving cylinder 15 drives the slide plate 14 to move the transfer plate 20 and the fixed baffle 21 to the initial position, and the lifting cylinder 16 lifts the transfer plate 20 and the fixed baffle 21 upwards through the lifting operation until the transfer plate 20 and the fixed baffle pass through the through slot 121, and the transfer plate 20 is located on one side of the workpiece. Then the transfer motor 19 is started, and the first of the four transfer plates 20 is driven by the screw to push the workpiece from the loading port 122 to the first grinding station 123, the second one pushes the workpiece at the first grinding station 123 to the second inspection station 124, the third one pushes the workpiece on the second inspection station 124 to the third grinding station 125, and the fourth one pushes the workpiece on the third grinding station 125 to the material port. When the corresponding workpiece moves to the corresponding designated position, it is blocked by the corresponding fixed baffle 21, and the transfer motor 19 stops moving. At the same time, the pressing cylinder 33 moves downward until the pressing block 34 presses the workpiece, and the lifting cylinder 16 drives the transfer plate 20 and the fixed baffle 21 to move downward to disengage from the through slot 121. At this time, the first grinding assembly, the second detection assembly and the third grinding assembly work simultaneously. The electric control during this operation is controlled by the controller on the workbench 1111. The overall structure is simple, the cost is low, and automatic grinding is realized, the grinding efficiency is high, and the grinding accuracy is significantly improved.

[0021] Furthermore, the controller can perform data analysis and issue instructions based on the analyzed data. Specifically, the second detection component sends the detection image of the workpiece after being polished by the first polishing component to the controller. The image analysis module set in the controller identifies the light spot or dark spot based on the detection image, and virtualizes the workpiece into a chessboard model, calculates the position of the light spot or dark spot, and controls the driving cylinder 15, the lifting cylinder 16, the transfer motor 19, the position detection sensor 127 and the clamping cylinder 33 through the controller to transfer the workpiece to the third polishing position, and controls the third polishing component to polish the light spot or dark spot position. Through this image detection and analysis, the unpolished parts of the workpiece can be polished again, thereby ensuring the accuracy of the workpiece polishing.

[0022] Specifically, the second detection component includes: a connecting frame 31, and two sides of the connecting frame 31 are respectively provided with inclined image collectors 32, and the two sides and the inner side of the workpiece can be imaged by the inclined image collectors 32. The two image collectors 32 send the collected images to the controller, and then the image analysis module of the controller performs a three-dimensional puzzle of the two image collectors 32 to form a complete workpiece image, making the image analysis more accurate.

[0023] As a further solution, the first grinding component and the third grinding component are also provided with an industrial camera 30, which is connected to the controller for communication. When in operation, the industrial camera 30 is used to take real-time photos of the workpiece being ground, and send the collected pictures to the controller in real time. The air conditioner performs picture analysis and processing inside: the picture analysis module performs real-time analysis on the pictures collected by the first grinding component, identifies the light spots and dark spots on the grinding surface in real time, and virtualizes the workpiece into a chess grid model, calculates the position of the light spots or dark spots, and the controller controls and adjusts the grinding position of the grinding head 23 of the first grinding component according to the real-time position of the light spots or dark spots; the picture analysis module performs real-time analysis on the pictures collected by the third grinding component, identifies the light spots and dark spots on the grinding surface in real time, and virtualizes the workpiece into a chess grid model, calculates the position of the light spots or dark spots, and then the picture analysis module compares the real-time position of the light spots or dark spots in the pictures collected by the third grinding component with the position of the light spots or dark spots in the detection picture, calculates the error value of the two pictures, and controls the corresponding grinding head 23 to grind the overlapping position of the two positions and the position within the error value range. The error value here is the part that exceeds each other in the two pictures. Through such control operation, the grinding head 23 can be driven to grind the workpiece accurately, and the grinding position of the grinding head 23 can be adjusted in real time according to the shooting situation, so that the grinding accuracy is higher.

[0024] As a specific structure, the first grinding assembly and the third grinding assembly each include: two grinding cylinders 22, a grinding head 23 installed on the cylinder rod end of the grinding cylinder 22, and an adjustment structure adapted to each grinding cylinder 22. The grinding cylinder 22 is installed above the adjustment mechanism, so that the position of the corresponding grinding cylinder 22 and the grinding head 23 is adjusted by the adjustment mechanism, thereby realizing all-round grinding of the workpiece, that is, after grinding one side of the workpiece, the grinding head is moved to the other side of the workpiece for grinding.

[0025] The above-mentioned adjustment mechanism includes: a transverse guide rail 24, a transverse slider 25 slidably mounted on the transverse guide rail 24, and a transverse driving screw 26 mounted on the workbench 1111 to drive the transverse slider 25 to slide, so that the grinding cylinder 22 and the grinding head 23 can be driven to move in the transverse direction through the transverse driving screw 26. Above the above-mentioned transverse slider 25, there are: a vertical slide rail 27, a vertical slider 28 slidably mounted on the vertical slide rail 27, and a vertical driving screw 29 mounted on the transverse slider 25 to drive the vertical slider 28 to slide. The grinding cylinder 22 is mounted on the vertical slider 28, so that the grinding cylinder 22 and the grinding head 23 can be driven to move in the vertical direction through the vertical driving screw. Through the above-mentioned mechanical structure, the position of the die head can be adjusted in the horizontal direction, so that the grinding head 23 can fully contact the grinding surface of the workpiece, and move and grind on the grinding surface, so that the grinding is more uniform.

[0026] In the above scheme, a first mounting frame 101 is provided on the vertical slider 28 of the third grinding assembly for mounting the grinding cylinder 22, and a first angle adjustment cylinder 102 is also installed for adjusting the angle between the first mounting frame 101 and the vertical slider, thereby adjusting the grinding angle of the grinding head 23. The cylinder rod of the first angle adjustment cylinder 102 is rotatably connected to the oblique push plate of the mounting frame, so that when the cylinder is extended or retracted, the corresponding grinding cylinder 22 can be pushed to perform angle fine adjustment.

[0027] In the above scheme, the adjustment structure of the first grinding assembly is further provided with an adjustment frame 201, a second mounting frame 202 and a second angle adjustment cylinder 203, and the adjustment frame 201 is provided with a height adjustment cylinder 204 for driving the grinding cylinder 22 to move up and down. Among them, the adjustment frame 201 is used to raise the grinding head 23, the second mounting frame 202 is used to install the grinding cylinder 22, and the second angle adjustment cylinder 203 is used to adjust the grinding angle of the grinding head 23. During installation, the second mounting frame 202 is slidably arranged in the adjustment frame 201 along the up and down direction, the cylinder rod end of the height adjustment cylinder 204 is connected to the upper end of the second mounting frame 202 to drive the grinding cylinder 22 to move up and down, and the second angle adjustment cylinder 203 is installed in the adjustment frame 201, and its cylinder rod end is connected to the second mounting frame 202 so that the second mounting frame 202 rotates relative to the adjustment frame 201, thereby adjusting the corresponding grinding cylinder 22, that is, the grinding angle of the grinding head 23. In this way, the grinding position of the grinding head 23 can be adjusted according to workpieces of different sizes, and the corners of the workpiece can be effectively ground by controlling various components through the controller, resulting in a better grinding effect.

[0028] Specifically, the second mounting frame 202 includes: an upper and lower sliding frame 205 and an oblique rotating frame 206. During installation, the upper and lower sliding frame 205 is slidably connected to the adjusting frame 201 and fixedly connected to the cylinder rod end of the height adjusting cylinder 204. The oblique rotating frame 206 is rotatably mounted on the upper and lower sliding frame 205. Then, the polishing cylinder 22 is mounted on the oblique rotating frame 206. The second angle adjusting cylinder 203 is mounted on the upper and lower sliding frame 205, and its cylinder rod end is rotatably connected to the oblique rotating frame 206. The polishing cylinder 22 is installed by such a split frame, so that the upper and lower sliding structure and the angle adjustment structure are independent of each other, the installation structure is simple, and the structure is stable.

[0029] The position and angle adjustment of the grinding head 23 are all performed by the controller to analyze the pictures collected by the industrial camera 30 and the image collector in real time, and the components are controlled in real time to drive and adjust according to the picture analysis results, which is more intelligent. During operation, the first grinding component first grinds according to the preset grinding path, and then performs targeted grinding of unqualified parts according to the picture detection results, so that the grinding effect is better.

[0030] As a specific embodiment, the outer circumference of the grinding head 23 is detachably covered with a dust collection assembly. The dust collection assembly includes: a dust box 302, a negative pressure pipeline 304 and a negative pressure pump 305, one end of the negative pressure pipeline 304 is connected to the box cavity of the dust box 302, and the negative pressure pump 305 is connected to the other end of the negative pressure pipeline 304. During installation, the dust box 302 is covered on the outer circumference of the grinding head 23, so that the grinding dust can be collected by the dust collection assembly to prevent dust splashing and affecting the picture collection. At the same time, the grinding station and the workpiece are cleaner. Specifically, the sliding cover of the dust box 302 is set on the outer circumference of the mounting rod 301 of the grinding head 23, and the mounting rod 301 of the grinding head 23 is provided with a micro cylinder 306 for driving the dust box 302 to extend and retract along the extension direction of the mounting rod 301. In this way, the micro cylinder 306 controls the dust box 302 to move between the dust collecting position and the retracted position to control the distance between the end of the dust box 302 and the end of the grinding head 23 within a preset range to ensure that the grinding operation of the grinding head 23 is not affected and the image collection is not affected.

[0031] Furthermore, a distance sensor 303 is provided at the end of the dust box 302 for detecting the distance from the dust box 302 to the grinding surface of the workpiece. When the detection value of the distance sensor 303 is less than a preset value, information on replacing the grinding head 23 is sent. In this way, the wear of the grinding head 23 can be understood in real time based on the detection information of the distance sensor 303. When the change value of the distance from the dust box 302 to the grinding surface of the workpiece exceeds the preset value, the controller will remind you to replace the grinding head 23. For each new workpiece, the controller can control the grinding head 23 to move to the detection position. The detection position of this solution is the side of the grinding head 23 facing the horizontal surface to be polished of the workpiece, thereby improving the accuracy and reliability of the wear information of the grinding head 23 detected by the distance sensor 303.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present invention.
