[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following is combined Figures 1 to 3 The following describes embodiments of the present invention.

[0027] According to an embodiment of the present invention, a feed rate detection and compensation device is provided, comprising: a working mechanism, a detection mechanism 5, and a control mechanism 6.

[0028] Specifically, the working mechanism includes a cutting tool 1 and a cutting tool drive structure 2. A worktable 3 is disposed below the cutting tool 1, and a substrate 4 is supported on the worktable 3. The cutting tool drive structure 2 is used to drive the cutting tool 1 to move towards or away from the worktable 3. A detection mechanism 5 is disposed above the cutting tool 1. The detection mechanism 5 includes a sensor 501 and a detection element 502. The detection element 502 is movably disposed above the cutting tool 1. The cutting tool drive structure 2 is used to drive the cutting tool 1 to move towards the detection element 502, so that the cutting tool 1 abuts against the detection element 502 and drives the detection element 502 to move. The sensor 501 is used to detect the position information of the detection element 502.

[0029] In this embodiment, the cutting tool 1 is a disc cutting tool 1, and a worktable 3 is provided below the cutting tool 1. The worktable 3 carries the substrate 4. The cutting tool driving structure 2 is used to drive the cutting tool 1 to move towards the worktable 3 to cut the substrate 4 on the worktable 3. After the cutting is completed, the cutting tool driving structure 2 can drive the cutting tool 1 to move away from the worktable 3 to complete the reset. After the tool 1 has been used for a period of time, its diameter will change, and the tool 1 needs to be detected and compensated. At this time, the tool drive structure 2 can drive the tool 1 to move away from the worktable 3, that is, to move closer to the detection part 502, so that the tool 1 abuts against the detection part 502. The tool 1 can drive the detection part 502 to move. The sensor 501 is set above the detection part 502 and located on one side of the detection part 502. When the detection part 502 moves to the same plane as the detection part of the sensor 501, the sensor 501 will transmit the detection data to the control mechanism 6. The control mechanism 6 can calculate the diameter of the tool 1 based on the detection data. The control mechanism 6 can calculate the compensation value based on the diameter of the tool 1, and control the driving amount of the tool drive structure 2 based on the compensation value, thereby adjusting the feed amount of the tool 1.

[0030] Specifically, such as Figure 1 and Figure 2As shown, the feed rate of the tool driven by the tool drive structure 2 is H, and the distance between the tool 1 and the end face of the worktable 3 is H1. Therefore, the feed rate H

[0031] Specifically, the formula for calculating the diameter d1 of the worn tool 1 is: d1 = H2 - |P2 - P1|; the formula for calculating the distance H1 between the tool 1 and the end face of the worktable 3 is:

[0032] Preferably, in this embodiment, the control mechanism 6 is a PLC controller, and the sensor 501 is a photoelectric sensor 501.

[0033] ​It should be noted that by periodically detecting the wear condition of tool 1 and feeding the data back to control mechanism 6, control mechanism 6 can automatically adjust the feed rate of tool 1, thereby ensuring the accuracy and efficiency of the cutting equipment during machining. Furthermore, this feed rate detection and compensation device has a simple structure, is easy to operate and maintain, and greatly improves the machining efficiency and quality of the cutting equipment. In practice, the user can set the time interval for periodically detecting the wear condition of tool 1 through the operation interface of control mechanism 6. When the set time is reached, control mechanism 6 will automatically activate detection mechanism 5 to detect tool 1. In addition, this feed rate detection and compensation device can also be integrated with the control mechanism 6 of the cutting equipment to achieve automated control and intelligent management. By communicating with the control mechanism 6, the device can obtain the operating status and machining parameters of the cutting equipment in real time, further improving the machining efficiency and quality of the cutting equipment.

[0034] In one embodiment, the detection mechanism 5 further includes a reset structure 503 for resetting the detection element 502.

[0035] In this embodiment, as Figure 1 As shown, after the thrust of the tool 1 on the detection element 502 disappears, the reset structure 503 can drive the detection element 502 to reset in preparation for the next detection.

[0036] In one embodiment, the detection mechanism 5 further includes a detection fixing seat 504 and a first guide rod 505. The first guide rod 505 is movably inserted through the detection fixing seat 504, and one end of the first guide rod 505 is fixedly connected to the detection element 502.

[0037] In this embodiment, as Figure 1 As shown, the detection mechanism 5 includes two first guide rods 505, which are spaced apart. The lower ends of the two first guide rods 505 are fixedly connected to the detection element 502. When the detection element 502 is moved by force, it will drive the first guide rods 505 to move. The first guide rods 505 can guide the detection element 502 to prevent it from deviating, which would cause the detection element 502 to fail to detect and affect the accuracy of the data.

[0038] In one embodiment, the detection mechanism 5 further includes a limiting rod 506, which is movably inserted through the detection fixing seat 504. One end of the limiting rod 506 is fixedly connected to the detection element 502. A limiting element 507 is provided on the detection fixing seat 504 to limit the other end of the limiting rod 506.

[0039] In this embodiment, as Figure 1As shown, the limiting rod 506 is located between the two first guide rods 505. The upper end of the detection fixing seat 504 is provided with a limiting member 507. The lower end of the limiting rod 506 is fixedly connected to the detection member 502. When the detection member 502 is moved by force, the detection member 502 will drive the limiting member 507 to move. The upper end of the limiting rod 506 will move away from the limiting member 507. When the pushing force of the tool 1 on the detection member 502 disappears, the reset structure 503 drives the detection member 502 to reset. At this time, the upper end of the limiting rod 506 is reset, and the limiting member 507 limits the upper end of the limiting rod 506 to prevent the upper end of the limiting rod 506 from coming out of the detection fixing seat 504, thereby fixing the detection member 502 and preventing the detection member 502 from falling. Preferably, the reset structure 503 is a compression spring, which is sleeved on the limiting rod 506. One end of the compression spring is connected to the bottom of the detection fixing seat 504, and the other end of the compression spring is connected to the detection component 502.

[0040] Specifically, the upper end of the limiting rod 506 has a limiting part (not shown), the limiting member 507 is a nut, the diameter of the limiting rod 506 is smaller than the inner diameter of the nut, the diameter of the limiting part is larger than the inner diameter of the nut, and the limiting part can abut against the nut, thereby limiting the limiting rod 506.

[0041] In one embodiment, the tool drive structure 2 includes a drive fixed base 201, a movable member, and a drive member. The drive fixed base 201 is disposed above the tool 1, the drive member is disposed at the end of the drive fixed base 201 away from the tool 1, and the movable member is movably disposed through the drive fixed base 201. The movable member is connected to the tool 1, and one end of the movable member is connected to the drive member.

[0042] In this embodiment, as Figure 2 and Figure 3 As shown, the drive fixing seat 201 is positioned above the tool 1. The drive component can drive the tool 1 to move through the movable component. It should be noted that the drive fixing seat 201 is not located directly above the tool 1. The tool 1 and the drive fixing seat 201 are offset. The detection component 502 is located directly above the tool 1, and the detection fixing seat 504 is located on one side of the drive fixing seat 201.

[0043] Preferred, such as Figure 2As shown, the movable component is a lead screw 202, and the driving component is a servo motor 203. The lead screw 202 is rotatably mounted on the drive mounting base 201, and the servo motor 203 is fixedly mounted on the upper end face of the drive mounting base 201. The servo motor 203 is connected to the upper end of the lead screw 202, and a lifting nut 204 is threaded onto the lead screw 202. The cutting tool 1 is connected to the lifting nut 204. The servo motor 203 drives the lead screw 202 to rotate, and the lifting nut 204 on the lead screw 202 moves relative to it along the guide direction of the lead screw 202, thereby driving the cutting tool 1 to move. It should be noted that the driving amount in this embodiment is the servo position of the servo motor 203. The servo motor 203 is signal-connected to the control mechanism 6, and the servo motor 203 can transmit servo position information to the control mechanism 6. The control mechanism 6 adjusts the feed amount of the cutting tool 1 by controlling the output amount of the servo motor 203.

[0044] In other alternative embodiments, the movable component may be a connecting rod, the driving component may be a cylinder, the output end of the cylinder is connected to the connecting rod, and the output end of the cylinder is connected to the detection component 502 through the connecting rod.

[0045] In one embodiment, the tool drive structure 2 further includes a second guide rod 205, which is disposed on both sides of the lead screw 202. The second guide rod 205 is movably inserted through the drive fixing seat 201, and one end of the second guide rod 205 is fixedly connected to the tool 1.

[0046] In this embodiment, as Figure 2 As shown, the tool drive structure 2 includes two second guide rods 205, which are respectively disposed on both sides of the lead screw 202. The lower ends of the two second guide rods 205 are connected to the tool 1. When the tool 1 moves, the tool 1 will drive the second guide rods 205 to move. The second guide rods 205 can provide guidance for the tool 1 and prevent the tool 1 from deviating.

[0047] In this embodiment, as Figure 2 As shown, the working mechanism also includes a cutting fixed seat 206, which is fixedly connected to the lifting nut 204. One end of the second guide rod 205 is fixedly connected to the cutting fixed seat 206, and the tool 1 is rotatably mounted on the cutting fixed seat 206.

[0048] In this embodiment, as Figure 2 As shown, a cutting motor 207 is mounted on the cutting fixture 206, and the cutting motor 207 is connected to the cutting tool 1.

[0049] In this embodiment, as Figure 1 As shown, a probe 508 is provided on the detection component 502, and the cutter 1 abuts against the probe 508, thereby applying a thrust to the detection component 502.
