[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1-10The present invention provides a workpiece drilling device, including a base frame 1, a drive motor 8 on the top of the base frame 1, a drill bit 9 fixed to the output shaft of the drive motor 8 through a drill chuck, and the drive motor 8 being connected to the base frame 1 through an adjustment module, the adjustment module being used to adjust the drilling position of the drill bit 9. The top of the base frame 1 is fixed with a base 4 by bolts. The top of the base 4 is slidably connected with a slide table 10. A linear drive module for driving the slide table 10 to move longitudinally is provided between the slide table 10 and the base 4. The top of the slide table 10 is provided with a placement frame 26 that can rotate 90° laterally along the slide table 10. The placement frame 26 is connected to the slide table 10 through a rotation drive module. Both sides of the placement frame 26 are provided with a fixing module for fixing and limiting diagonal codes. When using, first place the corner bracket on the placement rack 26, and then use the fixing module to fix the corner bracket on the placement rack 26; Then the linear drive module is activated, which drives the slide table 10 to move longitudinally along the base 4, and delivers the corner code to the drilling position directly below the drill bit 9; Next, the position of the drive motor 8 is adjusted by adjusting the module to ensure that the drill bit 9 is aligned with the drilling mark of the corner code. The drive motor 8 is started, and its output shaft drives the drill bit 9 to rotate at high speed. At the same time, the adjustment module drives the drive motor 8 to move downward, so that the rotating drill bit 9 gradually contacts the corner code and completes the drilling, thereby completing the corner code drilling operation of the single board. After drilling on one side is completed, the rotary drive module is activated, which can rotate the placement frame 26 by 90° according to the drilling requirements, so that the other side of the corner code is parallel to the slide table 10. The slide table 10 supports the corner code and the placement frame 26. The linear drive module is activated to adjust the longitudinal position of the corner code to ensure that the corner code is accurately located below the drill bit 9. The position of the drive motor 8 is adjusted by adjusting the module, and the drive motor 8 is started. Its output shaft drives the drill bit 9 to rotate at high speed. At the same time, the adjustment module drives the drive motor 8 to move downward, so that the rotating drill bit 9 gradually contacts the corner code and completes the drilling, thereby completing the double-sided corner code drilling operation. After the drilling is completed, the drive motor 8 stops rotating and resets under the action of the adjustment module. The fixing module loosens the fixing of the corner code, and the linear drive module drives the slide table 10 back to the initial position so that the processed corner code can be taken out and a new corner code to be processed can be placed to start the next round of drilling operation. By using multiple modules in combination, the corner code punching process is automated, effectively reducing the intensity of manual labor. At the same time, the automated process avoids the safety risks that may be caused by manual operation, making the overall processing more stable and reliable.

[0035] In order to achieve an accurate 90° rotation of the placement rack 26; like Figures 4-6As shown, the rotary drive module includes two sliders 11 that slide on the top of the slide table 10. A connecting shaft 25 is provided between the two sliders 11, and the connecting shaft 25 passes through the placement frame 26 and is fixed to the placement frame 26. The placement frame 26 rotates along the connecting shaft 25. Both ends of the connecting shaft 25 pass through the sliders 11 and are connected to gears 24 by key. A rack 23 that works with the gears 24 is fixed to the top of the slide table 10 by bolts. When the placement rack 26 needs to be flipped, the movement of the slider 11 will drive the connecting shaft 25 to move, which in turn will drive the gear 24 to move. Since the gear 24 meshes with the rack 23, the gear 24 will rotate, which will drive the connecting shaft 25 to rotate synchronously with the placement rack 26, thus realizing the flipping operation of the placement rack 26. The top of the slide table 10 is fixed with a protective cover 17 by bolts. The gear 23 and the rack 24 are both located inside the protective cover 17. A clearance opening 18 is provided on one side of the protective cover 17. The clearance opening 18 is used to avoid the movement of the connecting shaft 25. The protective cover 17 provides a safe operating environment for the gear 24 and rack 23, preventing external debris from being drawn into the meshing area of ​​the gear 24 and rack 23. It also prevents operators from accidentally touching moving parts during equipment operation and causing injury, and can extend the service life of the gear 24 and rack 23.

[0036] A connecting rod 22 is fixed between two sliders 11 by bolts. A guide hole 21 is provided through one side of the slide table 10, and the connecting rod 22 slides in the guide hole 21. An electric push rod 12 is fixed to one side of the slide table 10 by bolts, and the movable end of the electric push rod 12 is fixed to the connecting rod 22. When the slider 11 needs to move, the electric push rod 12 is activated. Its movable end will drive the connecting rod 22 to move linearly along the guide hole 21. Since the connecting rod 22 is fixedly connected to the two sliders 11, the movement of the connecting rod 22 will synchronously drive the two sliders 11 to slide on the top of the slide table 10. Then, through the connecting shaft 25, the gear 24 and the placement frame 26 are moved as a whole. Under the meshing action of the gear 24 and the rack 23, the placement frame 26 is rotated 90° to meet the drilling requirements of different sides of the corner code. The guide hole 21 can precisely limit the movement direction of the connecting rod 22, ensuring the stability of the movement trajectory of the slider 11 and avoiding abnormal meshing of the gear 24 and rack 23 due to deviation, thereby ensuring the accuracy of the flipping angle of the placement frame 26 and the smoothness of the flipping process. By using the electric push rod 12, slider 11, gear 24, rack 23 and connecting shaft 25 together, the placement rack 26 can be automatically rotated 90°. This not only simplifies the manual operation process, but also ensures the consistency of the rotation angle through the precise cooperation of the mechanical structure, avoiding the angle deviation that may be caused by manual rotation, and further improving the positional accuracy of the double-sided punching of the corner code.

[0037] It should be noted that the electric push rod 12 is existing technology. It is used in conjunction with a magnetic switch, proximity switch or photoelectric switch to achieve precise control of the push rod's extension and retraction displacement. Those skilled in the art can set it according to actual needs.

[0038] In order to adjust the drilling position of drill bit 9; The adjustment module includes a fixed frame 3 fixed on the base frame 1. A hydraulic cylinder 5 is fixed to the top of the fixed frame 3 by bolts. A slide 7 is fixed to the movable end of the hydraulic cylinder 5 by bolts. A mounting seat 6 for mounting the drive motor 8 is provided on one side of the slide 7, and the mounting seat 6 is slidably connected on the slide 7. A guide frame 2 for moving and guiding the slide 7 is fixed to the top of the base frame 1 by bolts. The guide frame 2 can provide stable guidance for the up and down movement of the slide 7, so as to prevent the slide 7 from shaking or deviating during the movement and ensure the accuracy of the vertical position adjustment of the drill bit 9. When it is necessary to adjust the drilling position of drill bit 9, the slide 7 can be moved up and down along guide frame 2 by controlling the extension and retraction of hydraulic cylinder 5, thereby adjusting the vertical height of drill bit 9 and ensuring that its distance from the corner code surface meets the drilling requirements; at the same time, mounting base 6 can slide laterally along slide 7 to adjust the position of drill bit 9 in the horizontal direction and realize the lateral adjustment of drilling position. The sliding fit between the mounting base 6 and the slide 7 provides flexible operating space for adjusting the lateral position of the drill bit 9, enabling the drill bit 9 to accurately align with the drilling mark points at different lateral positions on the corner code. By combining the drive of the hydraulic cylinder 5 and the sliding adjustment of the mounting base 6, the adjustment module can achieve precise control of the drilling position of the drill bit 9 in three-dimensional space, meet the drilling requirements of different positions of the corner code, and further improve the applicability and drilling accuracy of the equipment. The mounting base 6 and the slide 7 are connected by a linear motor, and the mover of the linear motor is fixed to the mounting base 6. When the drill bit 9 needs to be adjusted laterally, the linear motor is started, and its mover will drive the mounting base 6 to slide smoothly along the lateral guide rail of the slide 7. Through the closed-loop control of the linear motor, the displacement of the mounting base 6 can be precisely adjusted, ensuring that the drill bit 9 can move quickly and accurately to the preset lateral drilling position. Compared to the traditional manual adjustment method, the linear motor drive not only improves the response speed of position adjustment, but also avoids the adjustment error caused by mechanical transmission backlash, which significantly improves the lateral positioning accuracy of drill bit 9 and meets the high-precision drilling requirements for multiple lateral holes in corner code processing.

[0039] In order to drive the slide 10 to move longitudinally; The linear drive module includes a clearance groove 13 on the top of the base 4. A DC motor 16 is fixed in the clearance groove 13 by bolts. The output shaft of the DC motor 16 is fixed to a lead screw 15 by a coupling. A connecting block 14 is provided on the outer circumference of the lead screw 15 for use with the lead screw 15, and the connecting block 14 is fixed to the slide table 10. When the slide table 10 needs to move longitudinally, the DC motor 16 is started. Its output shaft drives the lead screw 15 to rotate in the relief groove 13 through the coupling. Since the connecting block 14 is threadedly connected to the lead screw 15 and fixed to the slide table 10, the rotation of the lead screw 15 will be converted into the linear motion of the connecting block 14, thereby driving the slide table 10 to slide smoothly along the top guide rail of the base 4, realizing the position conveying of the corner code in the longitudinal direction. The placement of the clearance slot 13 provides installation space for the DC motor 16, lead screw 15 and connecting block 14, while avoiding interference between the moving parts of the linear drive module and other structures of the base 4, ensuring the smoothness of the longitudinal movement process. It should be noted that the cooperation between the lead screw 15 and the connecting block 14 is the cooperation between the slider, ball and lead screw of the ball screw module. Its structure and principle can be learned by those skilled in the art through the technical manual, and will not be described in detail here. The DC motor 16 can achieve precise control of speed and direction through the encoder. Combined with the lead parameter of the lead screw 15, it can accurately calculate and control the moving distance of the slide table 10 to meet the drilling position requirements after the corner code is flipped, further improving the automation level and processing accuracy of the equipment.

[0040] To fix the corner code in a fixed position; Please refer to Figures 7-9 The fixing module includes multiple sets of snap-fit ​​groups respectively arranged in the horizontal and vertical directions of the placement frame 26. The snap-fit ​​group includes at least two L-shaped frames 30 fixed to the placement frame 26. One end of the two L-shaped frames 30 is slidably connected to a clip 31. A clip groove 33 is opened on one side of the clip 31. A locking component for clamping the workpiece is provided between the L-shaped frame 30 and the clip 31. The locking assembly includes limiting holes 36 on the opposite sides of the card holder 31 and the L-shaped frame 30. The two limiting holes 36 are provided with elastic components that push the card holder 31 away from the L-shaped frame 30. The elastic components can be springs 35, elastic rubber columns, or gas springs, etc. In practical applications, the appropriate type of elastic component can be selected according to the fixing force requirements. The two card holders 31 located on the same side are fixed together by a connecting plate 32. When it is necessary to fix the installed corner bracket, first align the edge of the corner bracket with the positioning reference of the placement bracket 26, and press the corner bracket down. At this time, the side of the corner bracket will squeeze the inclined surface of the bracket 31, causing the bracket 31 to slide towards the L-shaped bracket 30. The spring 35 is compressed in the limiting hole 36 and generates a reverse elastic force. After the corner bracket is fully placed, the spring 35 releases its elastic force to push the card holder 31 back to its original position. The card slot 33 will lock the edge of the corner bracket. At the same time, the horizontal and vertical locking groups form a surrounding auxiliary fixation for the corner bracket from different directions to ensure that the corner bracket will not be displaced vertically or vertically on the placement frame 26. After the card holder 31 is reset, a single screw can be used to fix the card holder 31 and the L-shaped frame 30 to ensure that the card holder 31 will not be displaced during the drilling process. As a better option, such as Figure 10 As shown, the locking component can also be an indexing pin. After the diagonal brackets are closed and fixed, the indexing pin can be used to replace the spring 35 to fix the card holder 31 and the L-shaped frame 30. The indexing pin is installed on the card holder 31, and the pin end (pin head) of the indexing pin is inserted into the gap between the L-shaped frame 30 and the card holder 31, thereby restricting the sliding of the card holder 31 on the L-shaped frame 30, thereby completing the position fixation of the L-shaped frame 31. The specific model of the indexing pin can be selected according to actual needs. It is preferred to be a self-locking indexing pin, so as to ensure that the corner brackets will not be laterally displaced on the placement frame 26. When it is necessary to remove the processed corner bracket, pull the connecting plate 32 outward, which will cause the two brackets 31 on the same side to overcome the elastic force of the spring 35 and move towards the L-shaped frame 30, so that the slot 33 is disengaged from the edge of the corner bracket, and the corner bracket can be easily removed from the placement rack 26. The operation is convenient and efficient. The flexible components allow the fixing module to quickly and easily fix the corner code without the need for manual tightening or adjustment of complex fixing structures, which greatly shortens the corner code clamping time and improves the overall processing efficiency. The connecting plate 32 connects the two brackets 31 on the same side into a whole, so that when the operator releases the fixing, he only needs to pull one connecting plate 32 to control the movement of both brackets 31 at the same time. This simplifies the operation steps, improves the efficiency of corner code replacement, reduces non-processing time, and helps to improve the continuous operation capability of the overall equipment. In addition, the enclosed design of the horizontal and vertical locking assemblies restricts the freedom of the corner brackets from multiple dimensions, effectively preventing displacement of the corner brackets in the vertical, horizontal and vertical directions, and providing a reliable fixing guarantee for high-quality drilling operations.

[0041] To quickly replace corner brackets; At least one arc-shaped groove 29 is provided on both inner walls of the placement rack 26. An elastic ball 28 is placed in the arc-shaped groove 29 and protrudes from the arc-shaped groove 29. The arc-shaped groove 29 is semi-ellipsoidal (the cross-section is higher than the center of the ellipsoid), and the central axis and minor axis of the ellipsoid are the same length. The minor axis of the ellipsoid is the same as the diameter of the elastic ball 28. Grooves 27 are provided on both sides of the placement rack 26. The grooves 27 are designed to provide hand grip space when the operator picks up and puts down the corner brackets, so as to avoid difficulty in applying force due to the smooth edge of the placement rack 26, and to facilitate quick removal of the corner brackets from the placement rack 26. The side of the card holder 31 with the card slot 33 is a flat surface 34. When the corner bracket is installed on the placement rack 26, the corner bracket will compress the elastic ball 28 and deform it, and it will be completely located in the arc groove 29; Once the corner bracket is fully in place, the elastic ball 28 will compress the corner bracket under its own elasticity, forming elastic support for the corner bracket from below. Combined with the limiting effect of the fixed module, this further enhances the stability of the corner bracket placement. When the corner bracket needs to be removed from the placement rack 26, pull the connecting plate 32 outward, which will cause the two clips 31 on the same side to move against the elastic force of the spring 35 towards the L-shaped frame 30, so that the clip 33 is separated from the edge of the corner bracket. At this time, the elastic ball 28 that was squeezed and deformed will reset and push the corner bracket away from the placement rack 26. During this process, the flat surface 34 will contact the corner bracket to prevent the corner bracket from slipping off the placement rack 26 due to excessive pushing force, which plays a buffering and limiting role and ensures that the corner bracket can be taken out smoothly. The combination of the elastic ball 28 and the arc-shaped groove 29 utilizes elastic deformation to achieve auxiliary support and pop-out function for the corner code, simplifying the operation steps for changing the corner code, reducing manual intervention time, making the picking and placing of the corner code more convenient and efficient, and further improving the continuous operation capability of the equipment.

[0042] To ensure that the placement rack 26 will not be unable to rotate 90° due to the obstruction of debris; Please refer to Figure 5 Two suction heads 20 are provided on opposite sides of the two sliders 11. Both suction heads 20 are inclined. The top of the slider 11 is provided with an external air pipe 19 connected to an external negative pressure vacuum cleaner. The external air pipe 19 is connected to the two suction heads 20 on the same slider 11. When the placement rack 26 is flipped under the action of the rotary drive module, the negative pressure vacuum cleaner can be started simultaneously. The negative pressure vacuum cleaner generates negative pressure, which is transmitted to the vacuum head 20 through the external air pipe 19. The vacuum head 20 sucks up the debris and performs directional vacuuming on the gap between the placement rack 26 and the slide table 10, so as to remove the metal debris and dust generated during the drilling process in a timely manner. The tilted vacuum head 20 can remove debris in advance, preventing debris from getting stuck and causing the storage rack 26 to flip over; The use of the vacuum head 20 in conjunction with the external air pipe 19 provides a clean guarantee for the smooth rotation of the placement rack 26, effectively avoids equipment failure caused by debris interference, extends the service life of mechanical parts in the rotary drive module, and also reduces production interruptions caused by downtime for cleaning debris, further improving the continuity and stability of the overall processing.

[0043] It should be noted that both the drive motor 8 and the DC motor 16 are used in conjunction with the encoder, and the output rotation number and rotation angle are controllable and highly accurate. Those skilled in the art can set them according to actual needs. Furthermore, the technology of using a negative pressure vacuum cleaner is a mature existing technology, and the model XC5500-80 can be used. The specific structure and working principle are common knowledge well known to those skilled in the art. Those skilled in the art can select appropriate power and matching pipes and collection devices according to actual vacuuming needs, which will not be elaborated on here.

[0044] The present invention is used in the following steps: S1: First, align the edge of the corner bracket with the positioning reference of the placement bracket 26, and press the corner bracket down. At this time, the side of the corner bracket will press the inclined surface of the card holder 31, causing the card holder 31 to slide towards the L-shaped bracket 30. The spring 35 is compressed in the limiting hole 36 and generates a reverse elastic force. S2: After the corner bracket is fully placed, the spring 35 releases its elastic force to push the card holder 31 to reset. The card slot 33 will lock the edge of the corner bracket. At the same time, the horizontal and vertical locking groups form a surrounding auxiliary fixation on the corner bracket from different directions to ensure that the corner bracket will not be displaced vertically or vertically on the placement frame 26. S3: Start the DC motor 16. Its output shaft drives the lead screw 15 to rotate in the relief groove 13 through the coupling. Since the connecting block 14 is threadedly connected to the lead screw 15 and fixed to the slide table 10, the rotation of the lead screw 15 will be converted into the linear motion of the connecting block 14, which in turn drives the slide table 10 to slide smoothly along the top guide rail of the base 4, so that the angle code is located below the drill bit 9. S4: By controlling the extension and retraction of the hydraulic cylinder 5, the slide 7 is moved up and down along the guide frame 2, thereby adjusting the vertical height of the drill bit 9 and completing a single drilling operation. S5: The linear motor moves to drive the mounting base 6 to slide smoothly along the transverse guide rail of the slide block 7, changing the horizontal position of the drill bit 9, and realizing multiple drilling operations on one side. After drilling on one side is completed, the drive motor 8 stops rotating and resets. S6: Start the electric push rod 12. Its movable end will drive the connecting rod 22 to move linearly along the guide hole 21, thereby synchronously driving the two sliders 11 to slide on the top of the slide table 10. Then, through the connecting shaft 25, the gear 24 and the placement frame 26 move as a whole. Under the meshing action of the gear 24 and the rack 23, the placement frame 26 is rotated 90°. S7: During the flipping of the placement frame 26, the DC motor 16 is started again to change the position of the slide table 10, ensuring that the corner code is below the drill bit 9. Repeat steps S5-S6 to complete the corner code opening operation on the other side, and then complete the corner code drilling operation on both sides. S8: After the operation is completed, start DC motor 16 again to reset the corner code; S9: Pull the connecting plate 32 outward, causing the two card holders 31 on the same side to overcome the elastic force of the spring 35 and move towards the L-shaped frame 30, so that the card slot 33 is separated from the edge of the corner code. At this time, the elastic ball 28 that was squeezed and deformed returns to its original position and pushes the corner code away from the placement frame 26. During this process, the flat surface 34 will contact the corner code to prevent the corner code from slipping off the placement frame 26 due to excessive pushing force, thus playing a buffering and limiting role and ensuring that the corner code can be taken out smoothly. S10: Repeat steps S1-S10 in sequence to perform hole-opening operations on multiple corner codes. Through this cyclic operation mode, the equipment can achieve continuous and automated processing of corner codes, reducing manual intervention and lowering the risk of processing deviations caused by human error.
