Technical Field

[0001] The invention relates to a high-efficiency saw plate double-side grinding device. Background Art

[0002] The front and back of the saw blade need to be ground to ensure that the saw plate reaches the designed flatness and smoothness of the front and back surfaces, and its thickness meets the higher tolerance accuracy and equal thickness requirements;

[0003] In the prior art, the double-sided grinding equipment for the front and back sides of the saw plate generally includes an equipment body and a robotic arm. The robotic arm is responsible for loading and unloading and turning over the saw plate. During the turning over process, the robotic arm needs to take the saw plate out of the equipment body, turn the saw plate over with the cooperation of another robotic arm, and then put the saw plate back into the equipment body. In this way, a single or two grinding devices need to be equipped with two robotic arms to work normally, and the purchase cost of the robotic arms is relatively high. In addition, the saw plate is repeatedly placed in and taken out of the equipment body, which reduces the processing efficiency. Summary of the invention

[0007] The transfer arm swings 180 degrees with the rotating shaft to buckle the saw plate on the grinding table and then reset it. The grinding table drives the saw plate to slowly move back to the reset position, so that the grinding mechanism grinds the saw plate.

[0009] When one side of the saw board is ground, the transfer arm repeats the first action to suck up the saw board from the grinding table.

[0010] A wall panel is provided on both sides of the top of the machine body, and a clamping block is respectively connected to the two wall panels through a micro electric cylinder, and the two clamping blocks are respectively provided with a clamping groove corresponding to the saw board;

[0011] The transfer arm drives the turned-over saw board to be lifted until the saw board is between the two clamping blocks, and the two clamping blocks extend to clamp the saw board, and then the transfer arm releases the saw board and swings toward the grinding table again, and the second arm body retracts into the first arm body; then the transfer arm swings away from the grinding table again, passes under the clamped saw board and returns to the end of the machine body away from the grinding table, and during the return process, the first arm body rotates 180° in the opposite direction and the second arm body is reset, and finally the two clamping blocks retrieve the saw board and place the turned-over saw board on the grinding table again;

[0012] The clamping block is rotatably connected to the telescopic rod of the micro-electric cylinder through a torsion spring so as to adapt to the deviation between the electromagnet and the saw plate after the self-adaptive transfer arm rotates.

[0013] Specifically, the first driving mechanism is a multi-section electric cylinder, and the connecting block is connected to the piston rod of the multi-section electric cylinder.

[0014] Furthermore, a plurality of first nozzles are provided in the machine body on a side away from the grinding table.

[0015] Furthermore, a movable frame is connected to the left and right sides of the machine body, the grinding table is fixed on the top of the movable frame, and a second driving mechanism for driving the grinding table to rotate is also provided at the bottom of the movable frame.

[0016] Furthermore, a third driving mechanism for driving the movable frame to move is also provided in the machine body. The third driving mechanism is two first electric cylinders. The two first electric cylinders are respectively fixed on both sides of the machine body. The telescopic rods of the two first electric cylinders are respectively connected to the movable frame.

[0017] Furthermore, second nozzles are respectively provided on the movable frames on both sides of the grinding table.

[0018] Furthermore, a drainage groove is provided at the lower end of the body, and the drainage groove is a non-contrasting V-shaped groove.

A water guide groove is also provided below the discharge outlet of the drainage groove.

[0019] Furthermore, a positioning column corresponding to the central hole of the saw plate is also provided at the front end of the second arm body, and two electromagnets are symmetrically arranged at the front end of the second arm body, and the positioning column is located between the two electromagnets.

[0022] The beneficial effects of the present invention are:

[0023] The present invention designs a transfer arm that can flip the saw board in the machine body, which can improve the efficiency of the saw board in the double-sided grinding process, and has the advantages of simple structure and low manufacturing cost, so that multiple high-efficiency saw board double-sided grinding devices can be equipped with one mechanical arm to realize the automatic processing of saw board double-sided grinding, which can effectively reduce the purchase cost of the mechanical arm and reduce the manufacturing cost of the saw board;

[0024] The transfer arm is driven by a rotating shaft arranged in the machine body to swing. When turning over a saw board that has been ground on one side, the first arm body rotates 180° during the process of adsorbing and lifting the saw board to turn over the saw board. When it is lifted to be vertical to the horizontal plane, the transfer arm transfers the turned saw board to the two clamping blocks above the machine body for clamping, while its second arm body retracts and retrieves the saw board between the two clamping blocks after being reset from the bottom of the saw board. The rhythm is compact, which can improve the turning efficiency of the saw board and thus improve the processing efficiency.

[0025] In addition, after the transfer arm transfers the saw plate to between the two clamping blocks, it swings 5-30° toward the grinding table again to avoid the electromagnet rubbing against the saw plate surface during the retraction of the second arm body;

[0026] Finally, the transfer arm is also designed to be lightweight. Guide grooves are provided on both sides of the front of the first arm body. The second arm body is slidably connected to the first arm body on both sides through sliders. The first driving mechanism for driving the second arm body to extend and retract is arranged on the back of the first arm body and a turntable is arranged to avoid the position. The first driving mechanism is connected to the rear end of the second arm body through a connecting block, and the connecting block is displaced in the long groove of the first arm body.

[0037] When the transfer arm 3 swings with the rotating shaft 2 to one end of the body 1 away from the grinding table 4, the second arm body 9 is in an extended state, the electromagnet 10 is set upward, the mechanical arm clamps the saw board 11 to be ground and places it on the electromagnet 10 of the second arm body 9, the electromagnet 10 is energized to adsorb the saw board 11, and then the transfer arm 3 swings 180° with the rotating shaft 2, buckles the saw board 11 on the grinding table 4 and resets, the grinding table 4 drives the saw board 11 to slowly move back to the reset position, so that the grinding mechanism 5 grinds the saw board 11;

[0038] The front sides of the first arm body 8 are respectively provided with guide grooves corresponding to the second arm body 9, and the two sides of the second arm body 9 are respectively provided with sliders, and the two sliders are respectively located in the corresponding guide grooves to avoid the second arm body 9 from deflecting when the second arm body 9 is extended; in addition, in order to reduce the deadweight of the transfer arm 3, the thickness of the first arm body 8 and the second arm body 9 needs to be compressed. The guide groove structure not only ensures the strength of the first arm body 8 and the second arm body 9, but also plays a role in avoiding the electromagnet 10 on the second arm body 9; a first driving mechanism 12 that drives the second arm body 9 to retract and retract is also fixed to the rear end of the back side of the first arm body 8, a long groove 13 is also provided in the middle part of the first arm body 8, and a connecting block 14 is fixed to the rear end of the second arm body 9, and the connecting block 14 passes through the long groove 13 and is connected to the first driving mechanism 12, and the first driving mechanism 12 is arranged to avoid the turntable 7 to avoid affecting the rotation of the second arm body 9;

[0039] When one side of the saw board 11 is ground, the transfer arm 3 repeats the first action to suck up the saw board 11 from the grinding table 4; during the lifting process after the transfer arm 3 sucks up the saw board 11, the turntable 7 drives the first arm body 8 to rotate 180 degrees, so that the unground surface of the saw board 11 is set upward;

[0040] The top sides of the machine body 1 are provided with a wall panel 15, respectively. The two wall panels 15 are respectively connected with a clamping block 16 through a micro electric cylinder 17, and the two clamping blocks 16 are respectively provided with a clamping groove corresponding to the saw board 11;

[0041] When the transfer arm 3 drives the flipped saw plate 11 to be lifted to a state vertical to the horizontal plane, the saw plate 11 is located between the two clamping blocks 16, and the two clamping blocks 16 extend to clamp the saw plate 11, then the electromagnet 10 is powered off and stops adsorbing the saw plate 11, and the transfer arm 3 swings 5-30° toward the grinding table 4 again, and then the second arm body 9 retracts into the first arm body 8 (the design purpose of this action is to avoid the electromagnet 10 rubbing against the surface of the saw plate 11 during the retraction of the second arm body 9); the transfer arm 3 is driven by the rotating shaft 2 to swing 50-30° away from the grinding table 4 again. 75°, the transfer arm 3 passes under the clamped saw board 11 and returns to the end of the machine body 1 away from the grinding table 4. During the return process, the first arm body 8 reversely rotates 180° to reset, so as to make full use of the time during the return process and improve the processing rhythm; finally, the second arm body 9 extends out, and the transfer arm 3 swings toward the grinding table 4 again. When the electromagnet 10 abuts against the clamped saw board 11, the electromagnet 10 absorbs the saw board 11, and the two clamping blocks 16 retract and reset. The transfer arm 3 buckles the saw board 11 on the grinding table 4 again, and the grinding mechanism 5 grinds the other side of the saw board 11;

[0042] The clamping block 16 is rotatably connected to the telescopic rod of the micro-electric cylinder 17 through a torsion spring, so that the two clamping blocks 16 can swing to a certain extent, so as to adapt to the deviation between the electromagnet 10 and the saw plate 11 after the rotation of the adaptive transfer arm 3, thereby preventing the electromagnet 10 from being unable to effectively adsorb the saw plate 11 between the two clamping blocks 16.

[0043] Specifically, the first driving mechanism 12 is a multi-section electric cylinder, and the connecting block 14 is connected to the piston rod of the multi-section electric cylinder.

[0044] In another embodiment, in combination Figure 1-3 As shown, a plurality of first nozzles 18 are provided on a side of the machine body 1 away from the grinding table 4 , and the plurality of first nozzles 18 are used to flush the surface of the saw board 11 just placed into the machine body 1 .

[0045] In another embodiment, in combination Figure 1-3 As shown, a movable frame 19 is connected to the left and right sides of the machine body 1, the grinding table 4 is fixed on the top of the movable frame 19, and a second driving mechanism 20 for driving the grinding table 4 to rotate is also provided at the bottom of the movable frame 19. The movable frame 19 is a concave-shaped movable frame 19, and the tops of the two side plates and the two outer sides of the movable frame 19 are respectively provided with sliders. The machine body 1 is provided with guide rails 21 corresponding to each slider, and each slider is matched with the corresponding guide rail 21 to drive the grinding table 4 to rotate stably during the displacement process.

[0046] Specifically, the second driving mechanism 20 is a motor.

[0047] In another embodiment, in combination Figure 1 and Figure 2 As shown, the body 1 is also provided with a third driving mechanism 23 for driving the movable frame 19 to move. The third driving mechanism 23 is two first electric cylinders. The two first electric cylinders are respectively fixed on both sides of the body 1, and the telescopic rods of the two first electric cylinders are respectively connected to the movable frame 19.

[0048] In another embodiment, in combination Figure 1-3 As shown, the movable frames 19 on both sides of the grinding table 4 are also provided with second nozzles 24, which are used to spray water to rinse the surface of the saw plate 11 during grinding and rinse the grinding table 4 after grinding to avoid residual debris on the grinding table 4 and scratching the surface of the saw plate 11.

[0049] In another embodiment, if Figure 3 As shown, a drainage groove 25 is further provided at the lower end of the machine body 1. The drainage groove 25 is a non-contrasting V-shaped groove. The inclination amplitude of the drainage groove 25 on one side corresponding to the position of the grinding table 4 is greater than the inclination amplitude of the drainage groove 25 on the other side, so as to more thoroughly flush out the debris generated during the grinding process of the saw plate 11; a water guide groove 26 is also provided below the discharge port of the drainage groove 25 to guide water out of the machine body 1.

[0050] In another embodiment, in combination Figure 1 , Figure 2 and Figure 6 As shown, the front end of the second arm body 9 is also provided with a positioning column corresponding to the central hole of the saw plate 11, and the front end of the second arm body 9 is symmetrically provided with two electromagnets 10, and the positioning column is located between the two electromagnets 10 to facilitate the positioning of the saw plate 11 when it is inserted.

[0051] In another embodiment, a robotic arm is further included, and the robotic arm is arranged corresponding to multiple high-efficiency saw board 11 double-sided grinding devices. One robotic arm can alternately load and unload multiple high-efficiency saw board 11 double-sided grinding devices to save purchase costs without affecting processing efficiency.

[0052] In another embodiment, a detection mechanism is further included. After the saw plate 11 is ground, the robot arm clamps the saw plate 11 and places it on the detection mechanism to detect the grinding accuracy of the saw plate 11.

[0053] The working principle of the above structure is: initially, the transfer arm 3 in the machine body 1 is set away from the grinding table 4, the mechanical arm clamps a saw board 11 and places it on the front end of the second arm body 9 of the transfer arm 3, the electromagnet 10 of the second arm body 9 is energized to adsorb the saw board 11, and the first nozzle 18 sprays water to wash the saw board 11;

[0054] After the flushing is completed, the transfer arm 3 swings 180 degrees under the driving of the rotation, and the saw plate 11 is buckled on the grinding table 4 and reset. The grinding table 4 drives the saw plate 11 to rotate and move back and forth slowly at a uniform speed, so that the saw plate 11 passes under the grinding head of the grinding mechanism 5 for grinding;

[0055] After grinding, the grinding table 4 drives the saw plate 11 to be output from the bottom of the grinding mechanism 5, and the saw plate 11 keeps rotating for 5-10 seconds to dry the residual water on the saw plate 11, and then the grinding table 4 stops rotating; the transfer arm 3 swings 180 degrees again, sucks the saw plate 11 from the grinding table 4, and then the second nozzle 24 sprays water to rinse the grinding table 4;

[0056] When the transfer arm 3 sucks up the saw board 11 and then lifts it, the turntable 7 drives the first arm body 8 to rotate 180 degrees, so that the unground surface of the saw board 11 is arranged upward;

[0057] When the transfer arm 3 drives the flipped saw plate 11 to be lifted to a state vertical to the horizontal plane, the saw plate 11 is located between the two clamping blocks 16, and the two clamping blocks 16 extend to clamp the saw plate 11. Then, the electromagnet 10 is powered off and stops adsorbing the saw plate 11. The transfer arm 3 swings 5-30° toward the grinding table 4 again, and the second arm body 9 retracts into the first arm body 8. Then, the transfer arm 3 is driven by the rotating shaft 2 to swing away from the grinding table 4 again by 50-75°, and the transfer arm 3 is clamped. The held saw board 11 passes under and returns to the end of the machine body 1 away from the grinding table 4. During the return process, the first arm body 8 rotates 180° in the opposite direction to reset; finally, the second arm body 9 extends out, and the transfer arm 3 swings toward the grinding table 4 again. When the electromagnet 10 abuts against the clamped saw board 11, the electromagnet 10 absorbs the saw board 11, and the two clamping blocks 16 retract and reset. The transfer arm 3 buckles the flipped saw board 11 on the grinding table 4 again, and the grinding mechanism 5 grinds the other side of the saw board 11;

[0058] After both sides of the saw board 11 are ground, the transfer arm 3 swings again to suck the saw board 11 from the grinding table 4. The mechanical arm clamps the saw board 11 from the transfer arm 3 and places it on the detection mechanism to detect the grinding accuracy of the saw board 11. The saw board 11 that passes the detection is transported to the next process.
