Description

Technical Field

[0001] This utility model relates to the field of cabinet processing technology, specifically a safety flipping mechanism for cabinet production. Background Technology

[0002] In the cabinet production process, a large number of boards often need to be carved. In order to facilitate the processing of both sides of the boards, a flipping device is usually used.

However, in actual use, many existing flipping devices simply clamp the left and right sides of the boards to fix them. Due to the simple and limited fixing method, the fixing effect is poor. The boards may fall off during processing and flipping, which may cause injury to workers. The safety is poor and it is not conducive to use. Therefore, a safe flipping mechanism for cabinet production is proposed. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a safe flipping mechanism for cabinet production, which has the following beneficial effects:

[0014] This safety flipping mechanism for cabinet production works by placing the left and right ends of the board material on top of two support blocks. The board material is then positioned between two second clamping plates and below two pressure blocks. Next, the first electric telescopic rods on both sides are activated to move the two first clamping plates relative to each other until their opposite sides are tightly fitted against the left and right sides of the board material, thus clamping and fixing the left and right ends of the board. Then, two servo motors are activated to drive two drive bevel gears to rotate, which in turn drive two threaded rods to rotate via two driven bevel gears. During the rotation of the two threaded rods... This will cause two moving blocks and two pressing blocks to move downwards until the bottom of the two pressing blocks are tightly fitted with the top of the board, thereby clamping and fixing the top of the board. Finally, the two second electric telescopic rods can be activated to drive the two second clamping plates to move relative to each other until the opposite sides of the two second clamping plates are tightly fitted with the front and rear sides of the board, thereby clamping and fixing the front and rear ends of the board. By clamping and fixing the board from all directions—left, right, top, bottom, front, and back—the fixing effect is improved, thereby preventing the board from falling off, thus improving safety and ensuring the smooth progress of processing operations.

[0021] A first drive assembly 7 is fixedly installed on the outer side of the left mounting shaft 5, with one end movably connected to the inner top wall of the left U-shaped plate 4 and the other end extending to the bottom of the left U-shaped plate 4. The first drive assembly 7 includes a stepper motor 71. The stepper motor 71 is fixedly installed at the bottom of the left U-shaped plate 4. The model of the stepper motor 71 can be TDA101-5.

[0022] Two first clamping plates 8 are movably installed between the front and rear sides of the inner wall of the rectangular frame 6 and are symmetrically distributed from left to right. The first clamping plates 8 only have the tendency to move left and right. The front and rear ends of the left and right sides of the inner wall of the rectangular frame 6 are fixedly installed with first electric telescopic rods 9. The output ends of the first electric telescopic rods 9 on the left and right sides are fixedly connected to the opposite sides of the two first clamping plates 8 respectively. The two first electric telescopic rods 9 on the left and the two first electric telescopic rods 9 on the right are all driven synchronously by a synchronous control device. Support blocks 10 are fixedly installed at the bottom of the opposite sides of the two first clamping plates 8.

[0023] A rectangular block 11 is fixedly installed on the opposite sides of the two first clamping plates 8, located between the first electric telescopic rods 9 on the front and rear sides. A rectangular groove 12 is opened on the opposite sides of the two rectangular blocks 11. A threaded rod 13 is movably installed between the upper and lower sides of the inner wall of the two rectangular grooves 12. The lead angle of the threaded rod 13 is extremely small. A movable block 14 is movably installed on the top of the inner wall of the two rectangular grooves 12, with one end threadedly connected to the outer side of the two threaded rods 13 and the other end extending above the two first clamping plates 8. A third bearing is fixedly installed on the upper and lower sides of the inner wall of the two rectangular grooves 12. The threaded rod 13 is rotatably connected to the inner wall of the rectangular groove 12 through the third bearing. A threaded hole is opened on the top of the two movable blocks 14, which is adapted to the two threaded rods 13. A pressure block 15 is fixedly installed on the opposite side of the two movable blocks 14, with one end abutting against the opposite side of the two first clamping plates 8. The two pressure blocks 15 are located above the two support blocks 10.

[0024] Two rectangular blocks 11 are each fixedly mounted on opposite sides with a second drive assembly 16, one end of which extends into the interior of the two rectangular slots 12 and is fixedly connected to the outside of the two threaded rods 13. The second drive assembly 16 includes a servo motor 161. The bottom of the opposite sides of the two rectangular blocks 11 is fixedly mounted with a servo motor 161. The model of the servo motor 161 can be YB2-315S-6-70. The output shafts of the two servo motors 161 extend into the interior of the two rectangular slots 12 and are fixedly mounted with drive bevel gears 162. The outside of the two threaded rods 13 is fixedly mounted with a driven bevel gear 163 located below the moving block 14 and one end of which meshes with the two drive bevel gears 162.

[0025] The rectangular frame 6 has a mounting block 17 that extends into its interior at both ends on the front and rear sides. The rectangular frame 6 has connection holes that are compatible with the mounting block 17 at both ends on the front and rear sides. The two mounting blocks 17 on the left side are fixedly mounted with a second clamping plate 18 that is fixedly connected to the opposite side of the two mounting blocks 17 on the right side. The rectangular frame 6 has a second electric telescopic rod 19 that is fixedly mounted between the mounting blocks 17 on the left and right sides. The output ends of the two second electric telescopic rods 19 extend into the rectangular frame 6 and are fixedly connected to the opposite side of the two second clamping plates 18. The first electric telescopic rod 9 and the second electric telescopic rod 19 are both model YNT-03.

[0026] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0027] In use, place the left and right ends of the plate on top of the two support blocks 10 respectively. At this time, the plate is located between the two second clamping plates 18 and below the two pressure blocks 15. Then, activate the first electric telescopic rods 9 on both sides to drive the two first clamping plates 8 to move relative to each other until the opposite sides of the two first clamping plates 8 are tightly attached to the left and right sides of the plate, thereby clamping and fixing the left and right ends of the plate. Then, activate the two servo motors 161 to drive the two drive bevel gears 162 to rotate, which in turn drive the two threaded rods 13 through the two driven bevel gears 163. The two threaded rods 13 rotate, causing the two moving blocks 14 and two pressing blocks 15 to move downwards until the bottom of the two pressing blocks 15 are tightly fitted against the top of the plate, thus clamping and fixing the top of the plate. Finally, the two second electric telescopic rods 19 are activated to move the two second clamping plates 18 relative to each other until the opposite sides of the two second clamping plates 18 are tightly fitted against the front and rear sides of the plate, thus clamping and fixing the front and rear ends of the plate. By clamping and fixing the plate from all directions (left, right, top, bottom, front, and back), the fixing effect is improved. This prevents the board from falling off, thus improving safety and ensuring smooth processing. At this point, the top of the board can be engraved. When the board needs to be flipped, the stepper motor 71 is started to drive the worm gear 72 to rotate, which in turn drives the two mounting shafts 5 and the rectangular frame 6 to rotate as a whole via the worm wheel 73. By rotating the rectangular frame 6 180 degrees, the board is flipped, facilitating double-sided processing. After the board processing is complete, the stepper motor 71 can be started to rotate in the opposite direction... This causes the rectangular frame 6 to rotate 180 degrees in the opposite direction, thereby resetting the rectangular frame 6 (therefore, the rectangular frame 6 in this application rotates back and forth, rather than in one direction, in order to ensure the normal operation of the equipment). At this time, the two second electric telescopic rods 19 can be activated to drive the two second clamping plates 18 to move in opposite directions, the two servo motors 161 can be activated to drive the two pressure blocks 15 to move upward, and the first electric telescopic rods 9 on the left and right sides can be activated to drive the two first clamping plates 8 to move in opposite directions, thereby releasing the fixation of the board material. Then the board material can be removed for cabinet production and processing.

[0028] In summary, this safety flipping mechanism for cabinet production works by placing the left and right ends of the board material on top of two support blocks 10. The board material is then positioned between two second clamping plates 18 and below two pressure blocks 15. Next, the first electric telescopic rods 9 on both sides are activated to move the two first clamping plates 8 relative to each other until their opposite sides are tightly fitted against the left and right sides of the board material, thus clamping and fixing the left and right ends of the board material. Then, two servo motors 161 are activated to drive two drive bevel gears 162 to rotate, which in turn drive two threaded rods 13 to rotate via two driven bevel gears 163. During rotation, the threaded rods 13 move the two moving blocks 14 and two pressure blocks 15 downwards until the bottom of the two pressure blocks 15 is tightly fitted against the top of the board material, thus clamping and fixing the top of the board material. Finally, the two second electric telescopic rods 19 can be activated to move the two second clamping plates 18 relative to each other until the opposite sides of the two second clamping plates 18 are tightly fitted with the front and rear sides of the board, thereby clamping and fixing the front and rear ends of the board. By clamping and fixing the board from all directions (left, right, top, bottom, front, and back), the fixing effect is improved, thus preventing the board from falling off and improving safety. It also ensures the smooth progress of processing operations. This solves the problem that many existing flipping devices only clamp the left and right sides of the board to fix it in actual use. Due to the simple and limited fixing method, the fixing effect is poor, and the board may fall off during processing and flipping, which may easily cause injury to workers and has poor safety, thus making it unsuitable for use.
