When supporting, the rear support plate needs to be opened, that is, the support plate and the back adhesive plate are connected by a hinge, and the hinge connection requires punching at one end of the support plate.

[0020] Please refer to Figure 1-Figure 7The present invention proposes a double-sided punching machine, comprising a fixed machine platform 1, an alternating moving mechanical arm 2, a clamp locking mechanism 3, two drilling devices 4, and two feeding mechanisms 5. The alternating moving mechanical arm 2, the clamp locking mechanism 3, the two drilling devices 4, and the two feeding mechanisms 5 are all fixedly connected to the fixed machine platform 1 and are respectively electrically connected to the fixed machine platform 1. The fixed machine platform 1 is provided with a protective cover 11 and a control panel 12. The protective cover 11 protects the alternating moving mechanical arm 2, the clamp locking mechanism 3, the two drilling devices 4, and the two feeding mechanisms 5. The control panel The plate 12 is movably connected to one side of the protective cover 11, and the control panel 12 is electrically connected to the alternating moving robot arm 2, the clamp locking mechanism 3, the two drilling devices 4, and the two feeding mechanisms 5 through conductive wires. The worker can issue processing instructions to the alternating moving robot arm 2, the clamp locking mechanism 3, the two drilling devices 4, and the two feeding mechanisms 5 through the control panel 12 to make them perform automatic full-process operation or semi-automatic segmented operation. The two drilling devices 4 are symmetrically arranged, the clamp locking mechanism 3 is located between the two drilling devices 4, and the two drilling devices 4 are symmetrically arranged. The two positions 4 are all facing the front area of ​​the clamp locking mechanism 3, the alternating transfer robot arm 2 is located on one side of the two drilling devices 4 and extends to the top of the two drilling devices 4, the two feeding mechanisms 5 are respectively located on both sides of the clamp locking mechanism 3, the workpieces are alternately loaded and unloaded through the two feeding mechanisms 5, the alternating transfer robot arm 2 clamps the two workpieces and moves them to the clamp locking mechanism 3 for fixation, one of the drilling devices 4 drills the fixed workpiece, and after the workpiece is drilled, the alternating transfer robot arm 2 clamps and moves the workpiece, and The next workpiece is clamped and moved to the clamp locking mechanism 3 for fixation, and another drilling device 4 drills the fixed workpiece. During drilling, the alternating transfer robot arm 2 moves the drilled workpiece 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 drilled workpiece, and clamps the next workpiece and moves it to the clamp locking mechanism 3 for fixation, so as to perform one-to-one alternating drilling.

[0021] In this embodiment, the fixed machine 1 serves as a control center for issuing operation instructions and a support structure for installation. The fixed machine 1 can issue corresponding operation instructions to the alternating transfer robot arm 2, the clamp locking mechanism 3, the two drilling devices 4, and the two feeding mechanisms 5 through the control panel 12, so that the alternating transfer robot arm 2 alternately clamps and moves the workpiece, the clamp locking mechanism 3 clamps and fixes the workpiece moved by the alternating transfer robot arm 2, and the two drilling devices 4 respectively perform alternate one-to-one corresponding workpiece rotation. The two feeding mechanisms 5 are used for loading or unloading the workpieces respectively. In this way, during the time when the drilling device 4 is drilling, the alternating transfer robot arm 2 can complete the loading and unloading of the workpieces on the two feeding mechanisms. For example, after the machine is started, the alternating transfer robot arm 2 first clamps and moves the two workpieces to the top of the clamp locking mechanism 3 at the same time, and then places a workpiece in the clamp locking mechanism 3, and the clamp locking mechanism 3 clamps and fixes the workpiece. At this time, the alternating transfer robot arm 2 will leave a clamping position vacant, but the alternating The transfer robot arm 2 still stays above the clamp locking mechanism 3, and then the drilling device 4 on the left side drills the workpiece horizontally. After the workpiece is drilled, the alternating transfer robot arm 2 clamps the drilled workpiece out of the clamp locking mechanism 3, and then replaces another workpiece that has not been drilled to the clamp locking mechanism 3 for placement, and then the drilling device 4 on the right side drills the workpiece horizontally. During the drilling time, the alternating transfer robot arm 2 will first move the drilled workpiece to a feeding mechanism 5 for placement , the feeding mechanism 5 sends the workpiece out of the fixed machine table 1, and then the alternating moving robot arm 2 has two clamping positions at this time, and will move to another feeding mechanism 5 to clamp the workpiece to be drilled, and then move it to the top of the clamp locking mechanism 3. This process just completes the drilling of the previous workpiece, and then the alternating moving robot arm 2 repeats the above replacement process, and the two drilling devices 4 repeat the one-to-one corresponding alternating drilling process, so that the entire drilling process is seamlessly connected, and the drilling efficiency and automation of the workpiece are improved; In summary, the double-sided punching machine can improve the degree of automation of punching holes in workpieces, improve the drilling efficiency of workpieces, and thus improve the production efficiency of the enterprise.

[0022] In this embodiment, the alternating transfer robot 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 Z-axis lifting device 24 is used to drive the double-head clamping mechanism 25 to lift and lower, and then clamp, pick up and move 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, and then the Y-axis telescopic device 23 pushes the Z-axis lifting device 24 to the top of the workpiece of the feeding mechanism 5, and then the Z-axis lifting device 24 drives the double-head clamping mechanism 25 to descend to 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, and the subsequent steps are the same as the above steps. The double-sided punching machine also includes a first high-definition camera 7, which is fixedly connected to the fixed machine platform 1, located below the support beam 21 and angled toward the clamp locking mechanism 3.

The first high-definition camera 7 is used to obtain image information of the workpiece drilling, and then transmit it back to the fixed machine platform 1.

The two pneumatic clamps The claws 252 can be separated to perform clamping actions. During the process of replacing the workpiece on the clamp locking mechanism 3, one pneumatic claw 252 does not clamp the workpiece, and the other pneumatic claw 252 has already clamped the workpiece to be drilled. The pneumatic claw 252 that does not clamp the workpiece first clamps the workpiece on the clamp locking mechanism 3, and after lifting and moving it away, the other pneumatic claw 252 places the workpiece to be drilled on the clamp locking mechanism 3 to complete the replacement of the workpiece.

[0024] In this embodiment, the drilling device 4 includes a fixed seat 41, a driving device 42, a first sliding block 43, and a processing head 44. The fixed seat 41 is fixedly connected to the fixed machine table 1, the driving device 42 is fixedly connected to one end of the fixed seat 41, the first sliding block 43 is slidably connected to the upper surface of the fixed seat 41, the rotating shaft of the driving device 42 passes through the first sliding block 43 and forms a screw transmission connection with the first sliding block 43, and the processing head 44 is horizontally fixedly connected to the top of the first sliding block 43 and faces the clamp locking mechanism 3.

When drilling a workpiece, the processing head 44 is turned on, causing the drill bit to rotate at high speed, and the driving device 42 rotates forward to drive the first sliding block 43 to slide toward the workpiece, that is, the drill bit drills the workpiece horizontally at this time. After the drill bit passes through the workpiece, the driving device 42 rotates in the opposite direction to drive the first sliding block 43 to retreat, so that the drill bit is pulled out of the workpiece, completing the drilling process.

An alignment pin is provided on the fixed boss 311, which can be aligned with the positioning hole at the bottom of the workpiece. When the workpiece is fixed, the rotating telescopic cylinder 32 rotates and contracts to drive the pressing block 33 to press down, so that the other end of the pressing block 33 presses and fixes the workpiece. When the workpiece is released, the rotating telescopic cylinder 32 rotates and extends to drive the pressing block 33 to rise, so that the workpiece is released.

When the two drilling devices 4 alternately drill the workpiece clamped on the clamp locking 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 will not break during the drilling process, it is necessary to perform visual inspection on the drill bit within the time interval of alternating drilling. If the drill bit is If the sharpness of the head is less than the preset value, it is determined that the drill bit needs to be replaced, and the drill bit detection device 6 will issue a prompt to the worker to allow the worker to replace the drill bit of the drilling device 4 at the corresponding position; for example, when the drilling device 4 on the left is not drilling, it will retreat to a position where the drill bit detection device 6 can perform detection, and then rotate the drill bit 601 at a slow speed. The drill bit detection device 6 acquires an image of the slowly rotating drill bit 601, and then judges the sharpness of the blade from the gloss and color of the blade, and then judges whether the drill bit 601 has been blunted.

When lifting, the first drive motor 643 rotates to drive the lifting frame 6441 to lift on the support frame. When adjusting the distance, the second drive motor 6442 rotates to drive the front and rear sliding blocks 6443 to move. Slide back and forth so that the drill bit detection module 65 moves back and forth, and then obtains the best drill bit image. Since the drill bit detection module 65 has a certain weight, in order to make the lifting and lowering of the lifting frame 6441 smoother, two fixed pulleys 64411 are respectively provided on both sides of the lifting frame 6441, and a longitudinal guide rail 6421 is provided on the support frame 642. The two fixed pulleys 64411 are installed on both sides of the longitudinal guide rail 6421 in a clamping and sliding manner. The connecting line of the two fixed pulleys 64411 and the rotating shaft of the first driving motor 643 forms a triangular structure, so that the lifting frame 6441 can bear the weight of the drill bit detection module 65 while also being able to be stably lifted and lowered.

[0030] In this embodiment, the drill bit detection device 6 also includes a prompt component 66, which is fixedly connected to the top of the support frame 642 and electrically connected to the control board 62. The prompt component 66 includes a mounting plate 661, a prompt light 662, and a buzzer 663. The mounting plate 661 is fixedly connected to the top of the support frame 642. The prompt light 662 and the buzzer 663 are both fixedly connected to the mounting plate 661. The buzzer 663 is located on one side of the prompt light 662. The prompt light 662 and the buzzer 663 are both electrically connected to the control board 62. In order to be able to notify the workers in time, the prompt light 662 and the buzzer 663 are set. After detecting that the drill bit is passivated, the prompt light 662 will light up red and flash for a prompt, and the buzzer 663 will also sound.

[0031] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
