Description

Technical Field

[0001] This invention relates to the field of panel processing technology, specifically to an automatic panel material changing processing machine that is easy to adjust and adapt to different sizes. Background Technology

[0002] A panel processing machine is a CNC mechanical device that drills, engraves, and processes graphics on panels. It can process a wide variety of panels, mainly made of glass, wood, metal, etc.

[0003] The invention, with publication number CN209793230U and titled "A Calibration Device for Single-Sided Panel Drilling," states that "existing calibration devices for single-sided panel drilling have some shortcomings during use. For example, they cannot perform multiple calibrations inside the single-sided panel drilling equipment, resulting in reduced accuracy of single-sided panel drilling and failing to meet user needs." Specifically, existing panel processing machines are not convenient for adjusting internal precision, leading to reduced processing accuracy. The aforementioned panel processing equipment only achieves calibration by adjusting the internal position of the cutting head, thereby improving the accuracy of the processed panel. However, this equipment does not consider the position calibration step of the panel to be processed before processing.

[0004] Therefore, the above-mentioned equipment still has the following defects:

[0005] ① Because the above-mentioned equipment did not consider the calibration steps for the position of the panel to be processed before processing, the processing accuracy of the panel will be seriously affected by the non-alignment of the panel on the processing table. Some existing mature panel processing equipment is generally equipped with auxiliary fixtures, but these fixtures only achieve the clamping effect of the panel. They cannot adapt well to panels of different sizes, nor can they automatically correct and calibrate the position of the panel after it is placed. If this process is done manually, it will undoubtedly increase the workload of the workers. In addition, during the panel processing, the drill bit will cause the panel to be deflected due to friction. If the panel is not properly positioned and corrected, the overall accuracy of the panel processed by the panel processing machine will be greatly reduced, resulting in the processed panel failing to meet the standards.

[0006] ② At the same time, before the panel is processed, there may be some hard particles or debris on its surface. If it is not pre-treated, when the processing tool on the equipment comes into contact with the hard particles, it is very easy to cause the tool to chip, which will affect the service life and stability of the tool. In addition, the dust that falls off during grinding or drilling during the equipment processing also needs to be cleaned up in time. The existing dust handling methods mostly use air pump blowing or vacuum cleaner collection. However, the air pump blowing method will cause the dust to float around the equipment body, which will deteriorate the overall working environment of the equipment. At the same time, the addition of air pumps or vacuum cleaners will also increase the overall energy consumption of the equipment, resulting in greater energy consumption of the equipment, which is not conducive to the green development of the production process.

[0007] ③ In addition, after the existing panel processing machine finishes processing the panel, the worker usually picks it up directly. Since the panel is placed under the cutting tool during the processing, if the worker is not careful, he may directly touch the cutting edge of the tool when picking up the panel, which seriously threatens the worker's safety and is not conducive to safe production.

[0008] Therefore, in view of this, the present invention proposes an automatic panel changing processing machine that is easy to adjust in size to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0009] To address the aforementioned technical problems, this invention provides an automatic panel material changing machine that facilitates size adjustment and adaptation, thereby resolving the corresponding technical issues raised in the background section.

[0019] Preferably, in this invention, one end of the torsion spring is fixedly connected to the outer wall of the cam, and the other end of the torsion spring is fixedly connected to the bottom surface of the processing table.

[0020] Compared with the prior art, the beneficial effects achieved by the technical solution of the present invention are:

[0021] (1) Through the cooperation between the T-frame, swing rod, eccentric rod, connecting shaft, right angle adjuster and roller, the workpieces of different sizes can be automatically calibrated to the center of the processing table before processing, so as to achieve the center calibration effect of the workpieces. This can correct the skewed part of the workpieces when they are placed, avoid the processing error caused by the non-standard placement of the workpieces, prevent the offset caused by friction during the drilling and carving process, and greatly improve the processing accuracy of the workpieces.

[0022] (2) The brush head connected to the brush plate sweeps across the surface of the workpiece and moves backward, thereby automatically sweeping off hard particles, chips and other impurities on the surface of the workpiece, avoiding damage to the drilling tool caused by impurities, thereby reducing wear and tear on the drilling tool during operation and effectively improving the service life of the drilling tool.

[0023] (3) The spring piston rod at the front end of the piston cylinder is squeezed multiple times by the front end of the brush plate. When the pressure valve installed at the front end of the collection cylinder reaches the rated pressure value, the compressed gas inside the collection cylinder releases pressure instantly through the pressure valve. The collection cylinder will use the suction pipe to achieve the effect of timed suction of impurities, thus completing the cleaning of the processing table and cleaning of the debris left after processing. This avoids dust diffusion caused by the air pump blowing method and energy consumption of other air pump or vacuum cleaner equipment.

[0024] (4) The brush plate that moves forward pushes the workpiece lifted by the cam to move forward together, so that the workpiece can be taken away more easily after processing. The workpiece is pushed to a position closer to the worker, making it easier to pick up. This reduces the time consumption of manual labor and improves the production efficiency. At the same time, the brush plate pushes the workpiece away from the processing drill bit, thus effectively reducing the possibility of the worker being injured by contact with the processing drill bit during the process of taking away the workpiece, thereby improving the safety of the worker's operation during the process of taking the workpiece.

[0025] (5) By setting the rectangular frame on the brush plate, the operator only needs to place the workpiece in the rectangular frame to make simple pre-positioning of the workpiece. Therefore, the rectangular frame of the brush plate can play a good role in pre-positioning the workpiece. Attached Figure Description

[0050] The complete usage steps and working principle of the above embodiments are as follows:

[0051] Initial state: such as Figure 1 and Figure 13 As shown in the comparison, Figure 13 This is the initial state of the device in use. At this time, the brush plate 31 is at its maximum stroke, and simultaneously... Figure 1 As shown, since a through hole is provided on the rear side of the panel processing machine body 1 corresponding to the brush plate 31, and when the brush plate 31 is in the initial state, its rear end is inserted into the through hole on the rear side of the panel processing machine body 1, and at this time the T-shaped frame 21 is far away from the center of the processing table 12, the bottom cylinder 210 is in the push stroke state, and the initial state of the cam 45 protrusion is flush with the upper surface of the processing table 12.

[0052] In use: The operator places the workpiece 14 from the rectangular frame above the brush plate 31 onto the upper surface of the processing table 12. The operator only needs to align the workpiece 14 with the rectangular frame to make simple pre-positioning of the workpiece 14. Therefore, the rectangular frame of the brush plate 31 can play a good role in pre-positioning and limiting the placement of the workpiece 14.

[0053] like Figure 2 As shown, the operator adjusts knob 23 to rotate the adjusting shaft 22. Since the movable adjusting block 25 is connected to the adjusting shaft 22 by a thread, and the threads at both ends of the adjusting shaft 22 rotate in opposite directions, based on the principle of screw drive, the movable adjusting block 25 will move horizontally in opposite directions. Thus, the center distance between the movable adjusting blocks 25 can be adjusted by adjusting knob 23. Since the right angle adjuster 26 is rotatably connected to the movable adjusting block 25, the distance between the right angle adjusters 26 can be adjusted by adjusting the distance between the movable adjusting blocks 25. Before processing, the distance between the two sides of the right angle adjuster 26 needs to be adjusted to match the width of the workpiece 14. Since the distance between the two sides of the right angle adjuster 26 can be adjusted to match each other, and the distance between the right angle adjusters 26 corresponds to the width of the workpiece 14, the size of the workpiece 14 can be adjusted according to its specific width for different sizes of workpieces 14.

[0054] like Figure 9 As shown, the T-shaped frames 21 on the left and right sides are symmetrically distributed about the center of the processing table 12. There are two swing rods 212 connected to the T-shaped frames 21, and the swing rods 212 are symmetrical about the center of the connecting shaft 214. The swing rods 212 can swing around the hinge point between the swing rods 212 and the eccentric rod 213, and the eccentric rod 213 can rotate around the connecting shaft 214.

[0055] When the equipment starts, the controller 13 controls the cylinder 210 at the bottom of the processing table 12 to begin its return motion, such as... Figure 9As shown, at this time, the connecting plate 211 is driven by the cylinder 210 to begin horizontal displacement, and the T-shaped frame 21 connected to the connecting plate 211 is subjected to tension and, under the limitation of the fixed track 29, will be horizontally pushed towards the center of the processing table 12. Figure 4 and Figure 2 As shown, since the distance between the right-angle adjusters 26 has been adjusted to match the width of the workpiece 14 before processing, and due to the cooperation between the T-frame 21, the swing rod 212, the eccentric rod 213, the connecting shaft 214, and the right-angle adjusters 26, the right-angle adjusters 26 can move forward synchronously under the push of the T-frame 21. This causes the right-angle adjusters 26 and the rollers 28 to approach the outer walls of the four right angles of the workpiece 14. Since the included angle between the right-angle adjusters 26 is ninety degrees, when the rollers 28 contact the outer walls of the four right angles of the workpiece 14 during the movement, the rollers 28 rotate. As the T-frame 21 continues to advance, due to the synchronous movement, when the right angles of the right-angle adjusters 26 are completely aligned with the four corners of the workpiece 14... When fully aligned, the workpiece 14 will automatically adjust to the center of the processing table 12 under the action of the right-angle adjuster 26. At this time, the operator controls the cylinder 210 to stop moving through the controller 13, so that the workpiece 14 is clamped to a tight state. The distance that the cylinder 210 drives the right-angle adjuster 26 to move synchronously towards the center of the processing table 12 depends on the length of the workpiece 14. Therefore, for workpieces 14 of different sizes, they can be automatically calibrated to the center of the processing table 12 before processing, so as to achieve the center calibration effect of the workpiece 14. This can correct the skewed part of the workpiece 14 when it is placed, avoid the processing error caused by the non-standard placement of the workpiece 14 by manual placement, and thus greatly improve the processing accuracy of the workpiece 14.

[0056] like Figure 6 and Figure 7 As shown, when the eccentric rod 213 rotates, the swing rod 32 connected to the eccentric rod 213 rotates relative to the hinge point. Since a through hole is provided on the rear side of the panel processing machine body 1 corresponding to the brush plate 31, the brush plate 31 moves horizontally along the through hole as the swing rod 32 rotates. The brush head 33 is connected to the brush plate 31, and the brush plate 31 gradually moves horizontally to the rear from its initial state. Figure 13 and Figure 1 As shown in the comparison, at this time, the brush head 33 connected to the brush plate 31 sweeps across the surface of the workpiece 14 and moves backward synchronously, thereby automatically removing impurities such as particles and debris from the surface of the workpiece 14 that affect the processing accuracy.

[0057] At the same time, when the front end of the brush plate 31 moves backward, such as Figure 7As shown, the bottom front end of the brush plate 31 moves backward and contacts the spring piston rod of the piston cylinder 311 during the movement. At this time, air is squeezed into the piston cylinder 311. The air inside the piston cylinder 311 is first transported to the air guide pipe 310 through the one-way valve 312, and then enters the collection cylinder 37 through the air guide pipe 310. The front end of the brush plate 31 squeezes the spring piston rod at the front end of the piston cylinder 311 multiple times. When the pressure valve 39 installed at the front end of the collection cylinder 37 reaches the rated pressure value, the compressed gas inside the collection cylinder 37 releases pressure instantly through the pressure valve 39. The collection cylinder 37 will then use the suction pipe 36 to allow the suction port 35 to remove impurities at regular intervals, thus completing the cleaning of the processing table 12 and cleaning up the debris left after processing.

[0058] The front end of the collection cylinder 37 is equipped with an openable cylinder cover 38 for post-dust collection treatment. A dust filter screen is installed on the cylinder cover 38 to prevent dust leakage during the exhaust process. At this time, the processing table 12 and the processing parts 14 can be effectively cleaned and the dust can be effectively collected.

[0059] After processing is completed, the cylinder 210 drives the T-shaped frame 21 to move away from the workpiece 14. At this time, the brush plate 31 moves forward, and the push rod 41 connected to the front end of the brush plate 31 also moves synchronously with the brush plate 31. Figure 10As shown, the incomplete gear 42, mounted at the front end of the push rod 41, moves forward along its straight path. Since the gear rod 43 is on the path of the incomplete gear 42, and the incomplete gear 42 and the gear rod 43 can rotate relative to each other through gear meshing, when the incomplete gear 42 moves to the meshing position with the gear rod 43, the gear rod 43 will rotate. Since the gear rod 43 is fixed to the shaft at its center of rotation, and cams 45 are fixedly mounted at both ends of the shaft, when the gear rod 43 rotates, it will drive the cam 45 to rotate. At this time, the cam 45 will start rotating from the initial state. When the protruding part of the cam 45 rotates to the top, since its protruding part is horizontal in the initial state and the highest point of the cam 45 is flush with the upper surface of the processing table 12, when the tip moves upward, The workpiece 14, which has already been processed, is lifted and placed on the upper surface of the processing table 12. At the same time, since the incomplete gear 42 follows the movement of the brush plate 31, the upper part of the brush plate 31 is moving forward. The forward-moving brush plate 31 will push the workpiece 14, which is lifted by the cam 45, to move forward together. This makes it easier to remove the workpiece 14 after processing, and the workpiece 14 is pushed to a position closer to the operator, making it easier to pick up. This reduces the time spent by the operator and improves the production efficiency. Since the brush plate 31 pushes the workpiece 14 away from the processing drill 11, it effectively reduces the possibility of the operator coming into contact with the processing drill 11 and being injured during the process of removing the workpiece 14, thereby improving the safety of the operator during the process of picking up the workpiece.
