Description

Technical Field

[0001] This application relates to the field of metal tube cutting technology, and more specifically, to a device for cutting conductive tubes for flashlights. Background Technology

[0002] A flashlight is a handheld electronic lighting tool that is mainly powered by batteries and is convenient to carry and use. The conductive tube is set inside the flashlight body and works with the tail spring to act as a wire, which is then used to connect the battery, switch and light bulb to form a circuit.

[0003] Because one end of the conductive tube needs to be beveled, the current processing method involves first cutting the conductive tube to a specified length, and then using a cutting device to bevel one end to form the bevel. Therefore, only one conductive tube can be processed at a time, resulting in low processing efficiency. Furthermore, the existing cutting equipment has a low degree of automation and limited functionality, requiring manual feeding and unloading. The grinding of the beveled surface after cutting must be done in a separate grinding device, making the processing steps cumbersome, time-consuming, labor-intensive, and with high labor costs. This issue urgently needs to be addressed. Summary of the Invention

[0034] Each of the two grinding components is also provided with a receiving component 6 below the grinding wheel 54. The receiving component 6 includes a receiving chute 61 that is horizontally fixed to the bottom surface of the chip receiving disk 2, a guide chute 62 that is inclinedly fixed to the bottom surface of the chip receiving disk 2 and located to the left of the receiving chute 61, a pusher plate 63 that is vertically and movably disposed inside the receiving chute 61, and a pusher cylinder 64 that is fixed to the bottom surface of the chip receiving disk 2 and located on one side of the receiving chute 61.

The telescopic end of the pusher cylinder 64 is set horizontally to the left or right and fixed on the pusher plate 63.

[0035] Working principle: A certain number of metal tubes are horizontally placed into the storage hopper 45 of the feeding assembly 4. The moving end of the third electric slide 418 is driven to move downwards, causing the lifting plate 44 and the storage bar 411 to move synchronously until the swing side of the storage bar 411 is no higher than the top outer wall of the frame plate 43. The metal tubes inside the storage hopper 45 will then roll and rearrange themselves due to the gap in the positions of the lifting plate 44 and the storage bar 411. One metal tube will be above the storage bar 411 and roll into the limiting groove 4111. Then, the same process is repeated, using the third electric slide 418 to drive the lifting plate 44 and the storage bar 411 to move synchronously. All bars 411 move upward, thereby lifting the metal tube located in the limiting groove 4111 upward. The square shaft 46 moves synchronously with the storage bar 411. Since the square shaft 46 can only slide up and down in the guide groove 452 and cannot rotate, the metal tube will not fall off. When the square shaft 46 reaches the upper end of the guide groove 452, the moving end of the third electric slide 418 stops moving. During this process, the steering motor 414 is started to rotate its rotating shaft, which in turn drives the beam plate 413 and the two clamping modules to rotate through the steering shaft 412 until one of the clamping modules rotates to the top of the storage hopper 45.

[0036] Next, the telescopic end of the first lifting cylinder 415 in the drive clamping module extends outward to drive the first pneumatic finger 416 to move downward. At the same time, the two grippers of the first pneumatic finger 416 are driven to move away from each other to drive the two U-shaped clamps 417 to separate left and right until the two U-shaped clamps 417 are respectively located on the left and right sides of the metal tube. Then, the two grippers of the first pneumatic finger 416 are driven to move closer to each other to drive the two U-shaped clamps 417 to move towards the metal tube. This causes the two ends of each U-shaped clamp 417 to enter the two clearance grooves 4112 and clamp the metal tube. Then, the telescopic end of the first lifting cylinder 415 is driven to retract inward to drive the metal tube to leave the limiting groove 4111 and move upward to the top of the storage hopper 45. Then, the rotating shaft of the steering motor 414 is driven to rotate 180 degrees to drive the metal tube to the top right end of the second electric slide 39.

[0037] Next, the moving end of the second electric slide 39 is driven to move to the right to drive the clamping mechanism to move synchronously until it is above the two material support blocks 3121 on the moving clamping plate 312 in the clamping mechanism. Then, the first lifting cylinder 415 and the first pneumatic finger 416 are operated in the same way to lower the metal tube onto the two material support blocks 3121 and position it between the fixed clamping block 310 and the moving clamping plate 312. Then, the telescopic end of the clamping cylinder 311 is driven to extend outward to drive the moving clamping plate 312 to move to the right until the right outer wall of the fixed clamping block 310 presses the metal tube against the inner wall of the notch groove 3101. This completes the clamping and fixing of the metal tube.

[0038] Next, the moving end of the first electric slide 32 in the drive cutting assembly 3 moves downward to drive the cutting unit to move synchronously. Before moving, the blade 38 in the cutting unit is located above the middle of the metal tube. At the same time, the cutting motor 35 is started to make its rotating shaft rotate. Then, the cutting shaft 34 is driven to rotate by the two pulleys 36 and the belt 37, thereby driving the blade 38 to rotate. The metal tube is then cut into two sections of equal length to form two conductive tubes. Since the blade 38 is at a certain angle to the axis of the metal tube, the cutting surfaces of the two conductive tubes are both inclined planes with equal inclination. The first blade avoidance groove 3102 and the second blade avoidance groove 3122 can accommodate the blade 38 during cutting to prevent the blade 38 from contacting the fixed clamping block 310 and the moving clamping plate 312.

[0039] Next, the first reversing motor 57 in the gripping components of the two grinding mechanisms 5 is simultaneously activated to rotate its rotating shaft, thereby driving the second reversing motor 58 and the double-jaw chuck 59 to rotate 90 degrees. This causes the double-jaw chucks 59 in both gripping components to face the outer end of a conductive tube on the same side. Then, the jaws of the double-jaw chuck 59 are driven to move away from each other, and the telescopic end of the second lifting cylinder 56 is driven to extend outward, thereby driving the first reversing motor 57 to move downward. In turn, the second reversing motor 58 drives the double-jaw chuck 59 to rotate downward. 9. Move down until the outer end of the conductive tube is between the two jaws of the double-jaw chuck 59. Before that, the rotating shaft of the second reversing motor 58 needs to be driven to rotate so that the two jaws of the double-jaw chuck 59 are distributed left and right. Then, drive the two jaws of the double-jaw chuck 59 to move closer to each other to clamp the outer end of the conductive tube. Then, operate the second lifting cylinder 56 and the first reversing motor 57 in the same way to drive the conductive tube to move up first and then rotate, so that the beveled surfaces of the two conductive tubes are both located below the grinding wheel 54 in a grinding assembly on the same side.

[0040] Next, the telescopic ends of the moving cylinders 511 in the two anti-bending components are extended outward to drive each second pneumatic finger 512 to move horizontally toward a conductive tube on the same side. At the same time, the two grippers of each second pneumatic finger 512 are driven to separate until the two grippers of the second pneumatic finger 512 are respectively located on the upper and lower sides of the corresponding conductive tube. Then, the two grippers of each second pneumatic finger 512 are driven to move closer together to clamp the middle of each conductive tube. Then, the grinding motor 53 in the grinding component is started to rotate its rotating shaft, thereby driving each grinding wheel 54 to rotate. Then, the telescopic end of the second lifting cylinder 56 is driven to retract inward to drive the conductive tube to move upward, thereby causing the grinding wheel 54 to grind the beveled surface of the conductive tube.

[0041] After grinding is completed, the grinding motor 53 is turned off first. Then, the two jaws of the second pneumatic finger 512 are driven to separate to release the conductive tube. Next, the telescopic end of the moving cylinder 511 is driven to retract inward to make the second pneumatic finger 512 leave the conductive tube. Then, the two jaws of the double-jaw chuck 59 are driven to separate to release the conductive tube. The conductive tube will fall into the receiving chute 61 in a receiving assembly 6 on the same side and be located to the left of the pusher plate 63. When the conductive tubes in the receiving chute 61 accumulate to a certain number, the telescopic end of the pusher cylinder 64 is driven to retract inward or extend outward to drive the pusher plate 63 to move to the left, thereby pushing each conductive tube into the guide chute 62. Thus, each conductive tube rolls out automatically along the slope of the guide chute 62 to achieve automatic collection.

[0042] It is worth mentioning that when the metal tube is placed horizontally into the storage hopper 45, short pieces may be mixed in. These short pieces are generated in the previous fixed-length cutting process. In the past, metal tube cutting was done manually, so they could be manually removed. However, this invention uses automatic feeding, so short pieces cannot be manually removed. Therefore, a sorting unit must be used to automatically sort out the short pieces. If a short piece enters the limiting groove 4111 and is lifted to the highest point by the lifting plate 44 and the storage bar 411, the sensing ends of the two position sensors 418 in the sorting unit will detect both ends of the short piece. If either position sensor 418 fails to detect the short piece, the moving end of the third electric slide 418 will drive the lifting plate 44 and the storage bar 411 to continue moving upwards until... The worm gear 47 and worm 48 mesh with each other, and the square shaft 46 enters the round hole 453 and can rotate within the round hole 453. Then, the material removal motor 49 is started to rotate its rotating shaft, which in turn drives the worm gear 47 to rotate through the worm 48. This causes the square shaft 46 to drive the swing side of the storage bar 411 to swing to the right and above the left side of the guide plate 410. When it swings to a certain angle, the short material will leave the limiting groove 4111 by its own gravity and fall to the top of the guide plate 410. Then, it will roll along the slope of the guide plate 410, pass through the slot 451, and roll outward from the storage hopper 45, thus automatically removing the short material. After removal, the rotating shaft of the material removal motor 49 must be driven to reverse so that the swing side of the storage bar 411 can swing to the left and return to the vertical direction in the same way.

[0043] This invention can generate two conductive tubes with a single cut and simultaneously process bevels with equal angles at one end of both conductive tubes, thereby effectively improving processing efficiency. At the same time, automatic feeding and discharging are achieved by means of the feeding component 4, the gripping component and the receiving component 6 in the grinding mechanism 5, and the grinding component in the grinding mechanism 5 integrates the grinding process into the same equipment, thereby greatly improving the degree of automation and increasing processing functions to simplify the processing steps and achieve the effect of saving time and labor, and also significantly reducing labor costs.
