Description

Technical Field

[0001] This invention relates to the field of drilling machine technology, and more particularly to a double-sided drilling machine. Background Technology

[0002] As a support structure for the back of a mobile phone, mobile phone stands are becoming increasingly miniaturized in production. They consist of a back adhesive plate and a support plate. When providing support, the support plate needs to be pried open, as it is connected to the back adhesive plate via a hinge. This hinge connection requires drilling a hole at one end of the support plate. Due to the extremely small size of the support plate, a fixture is needed to pre-clamp the support plate (the fixture holding the support plate can be referred to as the workpiece) before drilling the hole at the exposed end.

[0003] Due to the huge demand for these small phone stands, companies are overwhelmed with orders. However, there is currently no equipment that can quickly and automatically drill holes in the support plate. A fully automatic horizontal double-sided drilling machine with patent number CN213593044U drills holes in objects by installing electric drill bits on both sides. However, its automation level is low. If it is applied to drilling holes in the support plate, the production efficiency will be low, and it will be difficult to increase the output per unit time.

[0004] Therefore, it is necessary to propose a double-sided punching machine to improve the automation of punching workpieces, thereby increasing production efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a double-sided punching machine to improve the automation of punching workpieces, thereby increasing production efficiency.

[0006] This invention is achieved through the following technical solution:

[0007] This invention proposes a double-sided drilling machine, comprising a fixed machine base, an alternating transfer robotic arm, a clamping mechanism, two drilling devices, and two feeding mechanisms. The alternating transfer robotic arm, the clamping mechanism, the two drilling devices, and the two feeding mechanisms are all fixedly connected to the fixed machine base and electrically connected to it. The two drilling devices are symmetrically arranged, and the clamping mechanism is located between them, with both drilling devices facing forward of the clamping mechanism. The alternating transfer robotic arm is located on one side of the two drilling devices and extends above them. The two feeding mechanisms are located on either side of the clamping mechanism. Workpieces are alternately loaded and unloaded via the two feeding mechanisms. The alternating transfer robotic arm clamps two workpieces and moves them to the clamping locking mechanism for fixation. One of the drilling devices drills a hole in the fixed workpiece. After drilling is completed, the alternating transfer robotic arm clamps and moves the workpiece, and then clamps and moves the next workpiece to the clamping locking mechanism for fixation. The other drilling device drills a hole in the fixed workpiece. During drilling, the alternating transfer robotic arm moves the drilled workpiece to one of the feeding mechanisms and clamps the workpiece to be drilled on the other feeding mechanism. After drilling is completed, the alternating transfer robotic arm clamps and moves the drilled workpiece, and then clamps and moves the next workpiece to the clamping locking mechanism for fixation, thus performing alternating drilling in a one-to-one correspondence.

[0008] Furthermore, the alternating transfer robotic arm includes a support beam, an X-axis sliding device, a Y-axis telescopic device, a Z-axis lifting device, and a dual-head clamping mechanism.

The rotary telescopic cylinder is vertically fixedly connected to one side of the alignment platform. One end of the pressing block is fixedly connected to the push rod of the rotary telescopic cylinder. The other side of the alignment platform is provided with a fixing boss for placing the workpiece. When fixing the workpiece, the rotary telescopic cylinder rotates and retracts, causing the pressing block to press down, so that the other end of the pressing block presses and fixes the workpiece.

[0012] Furthermore, the double-sided drilling machine also includes a drill bit detection device, which is fixedly connected to the fixed machine base and electrically connected to the fixed machine base. The drill bit detection device is located on one side of the two drilling devices, and both sides of the drill bit detection device face the drill bits of the two drilling devices respectively. When the two drilling devices alternately drill the workpiece clamped on the clamping mechanism, the drill bit detection device performs drill bit detection on one of the idle drilling devices.

[0013] Furthermore, the drill bit detection device includes a slide, a control board, a dual-bar motor, two sliding lifting mechanisms, and two drill bit detection modules. The bottom of the slide is fixedly connected to the fixed machine base. The dual-bar motor is laterally fixedly connected to the bottom of the slide. Sliding rails are provided at both ends of the slide. The two rotating shafts of the dual-bar motor extend into the two sliding rails respectively. The bottoms of the two sliding lifting mechanisms are slidably connected to the two sliding rails respectively, and the bottoms of the two sliding lifting mechanisms are respectively connected to the two rotating shafts of the dual-bar motor to form a screw drive connection. The two drill bit detection modules are fixedly connected to the two sliding lifting mechanisms respectively, and the two drill bit detection modules face the drill bits of the two drilling devices respectively.

[0014] Furthermore, the drill bit detection module includes a mounting frame, a second high-definition camera, and a linear infrared distance detection module. The mounting frame is fixedly connected to the lifting end of the sliding lifting mechanism. The second high-definition camera and the linear infrared distance detection module are both fixedly connected to the mounting frame. The linear infrared distance detection module is located on one side of the second high-definition camera and close to the drill bit clamping end of the drilling device. The second high-definition camera and the linear infrared distance detection module are both electrically connected to the control board.

[0015] Furthermore, the sliding lifting mechanism includes a second sliding block, a support frame, a first drive motor, and a lifting distance adjustment mechanism. The second sliding block is slidably connected to the sliding track. Each of the two shafts of the dual-bar motor is equipped with a lead screw, which forms a lead screw transmission connection with the second sliding block. The bottom of the support frame is fixedly connected to the top of the second sliding block. The first drive motor is vertically fixedly connected to the support frame. The support frame passes through the lifting distance adjustment mechanism and is slidably connected to it. The shaft of the first drive motor passes through the lifting distance adjustment mechanism and forms a lead screw transmission connection with it. The drill bit detection module is fixedly connected to the lifting distance adjustment mechanism.

[0016] Furthermore, the drill bit detection device also includes a prompting component, which is fixedly connected to the top of the support frame and electrically connected to the control board. The prompting component includes a mounting plate, a prompting light, and a buzzer. The mounting plate is fixedly connected to the top of the support frame, and the prompting light and the buzzer are both fixedly connected to the mounting plate. The buzzer is located on one side of the prompting light, and both the prompting light and the buzzer are electrically connected to the control board.

[0017] The beneficial effects of this invention are:

[0018] This invention uses a fixed machine base as the control center for issuing operating commands and as the supporting structure for installation. The fixed machine base can issue corresponding operating commands to the alternating transfer robotic arm, the clamping and locking mechanism, the two drilling devices, and the two feeding mechanisms. This allows the alternating transfer robotic arm to alternately clamp and move the workpiece, the clamping and locking mechanism to clamp and fix the workpiece moved by the alternating transfer robotic arm, the two drilling devices to perform alternating drilling on the workpieces to be drilled, and the two feeding mechanisms to load or unload the workpieces. In this way, while the drilling devices are drilling, the alternating transfer robotic arm can complete the loading and unloading of the workpieces on the two feeding mechanisms, making the entire drilling process seamless and improving the drilling efficiency and automation level. In summary, this double-sided drilling machine can improve the automation level of drilling workpieces, improve the drilling efficiency of workpieces, and thus improve the production efficiency of enterprises.

[0034] To more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0035] Please refer to Figures 1-7This invention proposes a double-sided drilling machine, comprising a fixed machine base 1, an alternating transfer robotic arm 2, a clamping locking mechanism 3, two drilling devices 4, and two feeding mechanisms 5. The alternating transfer robotic arm 2, clamping locking mechanism 3, two drilling devices 4, and two feeding mechanisms 5 are all fixedly connected to the fixed machine base 1 and electrically connected to it. The fixed machine base 1 is equipped with a protective cover 11 and a control panel 12. The protective cover 11 protects the alternating transfer robotic arm 2, clamping locking mechanism 3, two drilling devices 4, and two feeding mechanisms 5. Plate 12 is movably connected to one side of protective cover 11. Control panel 12 is electrically connected via conductive wires to alternating transfer robotic arm 2, clamping mechanism 3, two drilling devices 4, and two feeding mechanisms 5. Workers can issue processing commands to the alternating transfer robotic arm 2, clamping mechanism 3, two drilling devices 4, and two feeding mechanisms 5 through control panel 12, enabling them to operate automatically throughout the entire process or semi-automatically in segments. The two drilling devices 4 are symmetrically arranged, and the clamping mechanism 3 is located between the two drilling devices 4. The two workpieces are positioned facing the front area of ​​the clamping mechanism 3. The alternating transfer robotic arm 2 is located on one side of the two drilling devices 4 and extends above them. Two feeding mechanisms 5 are located on either side of the clamping mechanism 3. Workpieces are alternately loaded and unloaded via the two feeding mechanisms 5. The alternating transfer robotic arm 2 clamps two workpieces and moves them to the clamping mechanism 3 for fixation. One of the drilling devices 4 drills a hole in the fixed workpiece. After drilling is complete, the alternating transfer robotic arm 2 clamps and moves the workpiece. After clamping the next workpiece, it is moved to the clamping mechanism 3 for fixation. Another drilling device 4 drills holes in the fixed workpiece. During drilling, the alternating transfer robot arm 2 moves the workpiece that has been drilled to one of the feeding mechanisms 5, and clamps the workpiece to be drilled on the other feeding mechanism 5. After the previous workpiece is drilled, the alternating transfer robot arm 2 clamps and moves the workpiece that has been drilled, and clamps the next workpiece and moves it to the clamping mechanism 3 for fixation, so as to perform one-to-one alternating drilling.

[0036] In this embodiment, the fixed machine base 1 serves as the control center for issuing operating commands and the supporting structure for installation. The fixed machine base 1 can issue corresponding operating commands to the alternating transfer robotic arm 2, the clamping locking mechanism 3, the two drilling devices 4, and the two feeding mechanisms 5 through the control panel 12. This allows the alternating transfer robotic arm 2 to alternately clamp and transfer the workpiece, the clamping locking mechanism 3 to clamp and fix the workpiece transferred by the alternating transfer robotic arm 2, and the two drilling devices 4 to alternately drill holes in the workpieces to be drilled. The drilling device 4 performs drilling, while the two feeding mechanisms 5 respectively load or unload the workpiece. During the drilling time, the alternating transfer robotic arm 2 can handle the loading and unloading of the workpiece between the two feeding mechanisms. For example, after the machine starts, the alternating transfer robotic arm 2 first clamps and moves two workpieces simultaneously above the clamping locking mechanism 3. Then, it places one workpiece in the clamping locking mechanism 3, which then clamps and fixes it. At this point, the alternating transfer robotic arm 2 will have an empty clamping position. While the transfer robot arm 2 remains above the clamping mechanism 3, the drilling device 4 on the left performs a transverse drilling on the workpiece. After drilling is complete, the alternating transfer robot arm 2 removes the drilled workpiece from the clamping mechanism 3 and replaces it with another un-drilled workpiece placed on the clamping mechanism 3. Then, the drilling device 4 on the right performs a transverse drilling on the workpiece. During the drilling process, the alternating transfer robot arm 2 first moves the drilled workpiece to a feeding mechanism 5 for placement. The feeding mechanism 5 sends the workpiece out of the fixed machine base 1. Then, the alternating transfer robot arm 2 has two clamping positions and moves to another feeding mechanism 5 to clamp the workpiece to be drilled. Then it is moved to the top of the clamping locking mechanism 3. This process completes the drilling of the previous workpiece. Then the alternating transfer robot arm 2 repeats the above replacement process. The two drilling devices 4 repeat the one-to-one alternating drilling process. This makes the entire drilling process seamless and improves the drilling efficiency and automation of the workpiece.

[0037] In summary, this double-sided drilling machine can improve the automation of drilling workpieces, increase drilling efficiency, and thus improve the production efficiency of enterprises.

[0038] In this embodiment, the alternating transfer robotic arm 2 includes a support beam 21, an X-axis sliding device 22, a Y-axis telescopic device 23, a Z-axis lifting device 24, and a double-headed clamping mechanism 25. The bottom of the support beam 21 is fixedly connected to the fixed machine base 1. The X-axis sliding device 22 is fixedly connected to the top of the support beam 21. The Y-axis telescopic device 23 is fixedly connected to the sliding table 221 of the X-axis sliding device 22. The Z-axis lifting device 24 is fixedly connected to the push rod of the Y-axis telescopic device 23. The double-headed clamping mechanism 25 is fixedly connected to the push rod of the Z-axis lifting device 24 and faces downward. The X-axis sliding device 22, the Y-axis telescopic device 23, the Z-axis lifting device 24, and the double-headed clamping mechanism 25 are all electrically connected to the fixed machine base 1. The X-axis sliding device 22 is a lead screw motor used to drive the Y-axis telescopic device 23 to move horizontally. The Y-axis telescopic device 23 is driven by a cylinder. The device uses a cylinder to push out a push rod, which can quickly drive the Z-axis lifting device 24 to extend and retract. The Z-axis lifting device 24 is used to drive the double-headed clamping mechanism 25 to lift and retract, thereby clamping, picking up and moving the workpiece. When clamping the workpiece, since the feeding mechanism 5 is in two different positions, the X-axis sliding device 22 needs to first drive the Y-axis telescopic device 23 to the top of the feeding mechanism 5 on the left. Then, the Y-axis telescopic device 23 pushes the Z-axis lifting device 24 to the top of the workpiece in the feeding mechanism 5. Then, the Z-axis lifting device 24 drives the double-headed clamping mechanism 25 to descend and clamp the workpiece. Similarly, to clamp the workpiece in the feeding mechanism 5 on the right, the X-axis sliding device 22 needs to first drive the Y-axis telescopic device 23 to the top of the feeding mechanism 5 on the right. The subsequent steps are the same as described above.

[0039] The double-sided drilling machine also includes a first high-definition camera 7, which is fixedly connected inside the fixed machine base 1, located below the support beam 21 and angled toward the clamping mechanism 3. The first high-definition camera 7 is electrically connected to the fixed machine base 1 through a conductive wire. The first high-definition camera 7 is used to acquire image information of the workpiece drilling and then transmit it back to the fixed machine base 1. The fixed machine base 1 can then calculate the drilling time range of the workpiece and issue operation instructions corresponding to the time range to the alternating transfer robotic arm 2 to make it operate.

[0040] In this embodiment, the dual-head clamping mechanism 25 includes a U-shaped frame 251 and two pneumatic grippers 252. One end of the U-shaped frame 251 is fixedly connected to the push rod of the Z-axis lifting device 24, and the opening of the U-shaped frame 251 faces downward. The two pneumatic grippers 252 are respectively fixedly connected to the other end of the U-shaped frame 251 and are symmetrically arranged. Both pneumatic grippers 252 are electrically connected to the fixed machine base 1. The U-shaped frame 251 serves as a fixing structure for the two pneumatic grippers 252. The claws 252 can be separated to perform clamping actions. During the replacement of the workpiece on the clamping mechanism 3, one pneumatic claw 252 is not clamping the workpiece, while the other pneumatic claw 252 has already clamped the workpiece to be drilled. The pneumatic claw 252 that is not clamping the workpiece first clamps the workpiece on the clamping mechanism 3, lifts and moves it away, and then the other pneumatic claw 252 places the workpiece to be drilled on the clamping mechanism 3 to complete the replacement of the workpiece.

[0041] In this embodiment, the drilling device 4 includes a fixed base 41, a driving device 42, a first sliding block 43, and a machining head 44. The fixed base 41 is fixedly connected to the fixed machine base 1. The driving device 42 is fixedly connected to one end of the fixed base 41. The first sliding block 43 is slidably connected to the upper surface of the fixed base 41. The rotating shaft of the driving device 42 passes through the first sliding block 43 and forms a lead screw drive connection with the first sliding block 43. The machining head 44 is laterally fixedly connected to the top of the first sliding block 43 and faces the clamping locking mechanism 3. In the front area, the drive device 42 and the processing head 44 are both electrically connected to the fixed machine base 1. The drive device 42 is a high-torque stepper motor. When drilling a workpiece, the processing head 44 is turned on, causing the drill bit to rotate at high speed. The drive device 42 rotates in the forward direction, causing the first sliding block 43 to slide towards the workpiece. That is, at this time, the drill bit is drilling the workpiece laterally. After the drill bit passes through the workpiece, the drive device 42 rotates in the reverse direction, causing the first sliding block 43 to retract, so that the drill bit is pulled out of the workpiece, completing the drilling process.

[0042] In this embodiment, the clamping mechanism 3 includes an alignment platform 31, a rotary telescopic cylinder 32, and a pressing block 33. The bottom of the alignment platform 31 is fixedly connected to the fixed machine base 1. The alignment platform 31 is located between two drilling devices 4. The rotary telescopic cylinder 32 is vertically fixedly connected to one side of the alignment platform 31. One end of the pressing block 33 is fixedly connected to the push rod of the rotary telescopic cylinder 32. The other side of the alignment platform 31 is provided with a fixing boss 311 for placing the workpiece. The fixing boss 311 is provided with an alignment pin, which can be aligned with the positioning hole at the bottom of the workpiece. When fixing the workpiece, the rotary telescopic cylinder 32 rotates and retracts, causing the pressing block 33 to press down, so that the other end of the pressing block 33 presses and fixes the workpiece. When releasing the workpiece, the rotary telescopic cylinder 32 rotates and extends, causing the pressing block 33 to rise, so that the workpiece is released. At this time, the workpiece can be clamped and moved by the alternating transfer robot arm 2.

[0043] In this embodiment, the double-sided drilling machine also includes a drill bit detection device 6. The drill bit detection device 6 is fixedly connected to the fixed machine base 1 and electrically connected to the fixed machine base 1. The drill bit detection device 6 is located on one side of the two drilling devices 4, with both sides of the drill bit detection device 6 facing the drill bits of the two drilling devices 4 respectively. When the two drilling devices 4 alternately drill the workpiece clamped on the clamping mechanism 3, the drill bit detection device 6 performs drill bit detection on one of the idle drilling devices 4. In order to ensure that the drill bit does not break during the drilling process, it is necessary to perform visual inspection on the drill bit during the time interval between alternating drilling. If the drill bit... If the sharpness of the drill bit is less than a preset value, it is determined that the drill bit needs to be replaced. The drill bit detection device 6 will then issue a prompt to the worker, instructing the worker to replace the drill bit of the corresponding drilling device 4. For example, if the drilling device 4 on the left side is not drilling, it will retract to a position where the drill bit detection device 6 can perform the detection, and then slowly rotate the drill bit 601. The drill bit detection device 6 will acquire an image of the slowly rotating drill bit 601, and then determine the sharpness of the cutting edge from the gloss and color of the cutting edge, thereby determining whether the drill bit 601 has become dull. If the drill bit 601 has become dull, it will issue a prompt to the worker.

[0044] In this embodiment, the drill bit detection device 6 includes a slide 61, a control board 62, a dual-bar motor 63, two sliding lifting mechanisms 64, and two drill bit detection modules 65. The slide 61 has an inverted T-shaped structure, and its bottom is fixedly connected to the fixed machine base 1. The dual-bar motor 63 is laterally fixedly connected to the bottom of the slide 61. Sliding rails 611 are provided at both ends of the slide 61. The two rotating shafts of the dual-bar motor 63 extend into the two sliding rails 611 respectively. The bottoms of the two sliding lifting mechanisms 64 are slidably connected to the two sliding rails 611 respectively. The bottom of each component is connected to the two shafts of the dual-bar motor 63 via lead screw transmission. Two drill bit detection modules 65 are fixedly connected to two sliding lifting mechanisms 64, each facing the drill bit of the two drilling devices 4. The control board 62 is electrically connected to the fixed machine base 1, the dual-bar motor 63, the two sliding lifting mechanisms 64, and the two drill bit detection modules 65. The drill bit detection device 6 can adjust its detection position according to the height and retraction position of the drilling device 4. During adjustment, the drill bit detection module 65 first acquires the image and distance of the drill bit, and then transmits the information back to the control board. On the control board 62, based on the returned information, the control board 62 issues corresponding operation commands to the dual-bar motor 63 and the two sliding lifting mechanisms 64, thereby driving the sliding lifting mechanisms 64 to slide left and right, and simultaneously move up and down. This allows the drill bit detection module 65 to be positioned horizontally with the drill bit, and the tip of the drill bit to be located in the center area of ​​the image acquired by the drill bit detection module 65. After the position is adjusted, the drill bit needs to rotate slowly, and then the drill bit detection module 65 acquires an image of the drill bit rotating one revolution, which is then transmitted back to the control board 62 for judgment. The control board 62 is equipped with a data processing module, an image processing module, a storage module, and a drive module. The data processing module is electrically connected to the image processing module, the storage module, and the drive module. The data processing module is used to judge the image information returned by the image processing module, and to call the pre-stored images in the storage module for comparison. At the same time, it issues corresponding operation instructions to the drive module. The image processing module is used to receive the images returned by the drill bit detection module 65. The storage module is used to store the comparison images. The drive module is used to issue instructions to the dual-bar motor 63 and the two sliding lifting mechanisms 64.

[0045] In this embodiment, the drill bit detection module 65 includes a mounting frame 651, a second high-definition camera 652, and a linear infrared distance detection module 653. The mounting frame 651 is fixedly connected to the lifting end of the sliding lifting mechanism 64. The second high-definition camera 652 and the linear infrared distance detection module 653 are both fixedly connected to the mounting frame 651. The linear infrared distance detection module 653 is located on one side of the second high-definition camera 652 and close to the drill bit clamping end of the drilling device 4. The second high-definition camera 652 and the linear infrared distance detection module 653 are both electrically connected to the control board 62. The mounting frame 651 provides a stable mounting structure for the second high-definition camera 652 and the linear infrared distance detection module 653. 52 is used to acquire image information of the drill bit and transmit it back to the control board 62. The linear infrared distance detection module 653 is used to measure whether the drill bit is located at the center height of the second high-definition camera 652. The linear infrared distance detection module 653 is equipped with multiple small infrared distance sensors arranged in sequence, with a minimum of 9. The small infrared distance sensor located in the middle is at the height centerline of the second high-definition camera 652. When measuring the center of the drill bit, if the reading of the small infrared distance sensor located in the middle is the minimum value, and the readings of the small infrared distance sensors located on both sides of the middle gradually increase, it indicates that the drill bit is at the height centerline of the second high-definition camera 652, and the drill bit can be detected at this time.

[0046] In this embodiment, the sliding lifting mechanism 64 includes a second sliding block 641, a support frame 642, a first drive motor 643, and a lifting distance adjustment mechanism 644. The second sliding block 641 is slidably connected to the sliding rail 611. Both shafts of the dual-bar motor 63 are equipped with lead screws 631, which form a lead screw transmission connection with the second sliding block 641. The bottom of the support frame 642 is fixedly connected to the top of the second sliding block 641. The first drive motor 643 is vertically fixedly connected to the support frame 642. The support frame 642 passes through the lifting distance adjustment mechanism 644 and is slidably connected to it. The shaft of the first drive motor 643 passes through... The lifting distance adjustment mechanism 644 is connected to the lifting distance adjustment mechanism 644 via a screw drive. The drill bit detection module 65 is fixedly connected to the lifting distance adjustment mechanism 644. The first drive motor 643 and the lifting distance adjustment mechanism 644 are both electrically connected to the control board 62. When adjusting the horizontal position, the dual-rod motor 63 rotates, driving the screw 631 to rotate, which in turn drives the second sliding block 641 to slide laterally to adjust the position. When adjusting the height, the first drive motor 643 rotates, driving the lifting distance adjustment mechanism 644 to slide longitudinally relative to the support frame 642 to perform lifting and lowering movements, thereby adjusting the height of the drill bit detection module 65. The lifting distance adjustment mechanism 644 can adjust the distance between the drill bit detection module 65 and the drill bit, thereby adapting to different sizes of drill bits to obtain clearer images and compensating for the distance adjustment effect caused by focusing failure. The lifting distance adjustment mechanism 644 includes a lifting frame 6441, a second drive motor 6442, and front and rear sliding blocks 6443. The lifting frame 6441 and the support frame 642 form a longitudinal sliding connection, and the lifting frame 6441 and the rotating shaft of the first drive motor 643 form a screw connection. During lifting, the first drive motor 643 rotates to drive the lifting frame 6441 to rise and fall on the support frame. During distance adjustment, the second drive motor 6442 rotates to drive the front and rear sliding blocks 6443 to move. The drill bit detection module 65 is moved back and forth to obtain the best drill bit image. Since the drill bit detection module 65 has a certain weight, in order to make the lifting frame 6441 rise and fall more smoothly, two fixed pulleys 64411 are provided on both sides of the lifting frame 6441. The support frame 642 is provided with a longitudinal guide rail 6421. The two fixed pulleys 64411 are installed on both sides of the longitudinal guide rail 6421 in a clamping and sliding manner. The line connecting the two fixed pulleys 64411 and the shaft of the first drive motor 643 forms a triangular structure, so that the lifting frame 6441 can rise and fall stably while bearing the weight of the drill bit detection module 65.

[0047] In this embodiment, the drill bit detection device 6 further includes a prompting component 66, which is fixedly connected to the top of the support frame 642 and electrically connected to the control board 62. The prompting component 66 includes a mounting plate 661, a prompting light 662, and a buzzer 663. The mounting plate 661 is fixedly connected to the top of the support frame 642, and the prompting light 662 and the buzzer 663 are both fixedly connected to the mounting plate 661. The buzzer 663 is located to one side of the prompting light 662, and both the prompting light 662 and the buzzer 663 are electrically connected to the control board 62. In order to notify the workers in a timely manner, the prompting light 662 and the buzzer 663 are provided. After detecting that the drill bit is dull, the prompting light 662 will light up red and flash to indicate, and the buzzer 663 will also sound.

[0048] Of course, the present invention may have many other embodiments. Based on this embodiment, other embodiments obtained by those skilled in the art without any creative effort are all within the scope of protection of the present invention.
