DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0017] like Figure 1-2 As shown, a chip collector comprises an outer shell 11 and a bottom shell 7 arranged in the outer shell 11, chip trays 1 are arranged on both sides of the bottom shell 7, a cavity for accommodating the chip tray 1 is arranged on the outer shell 11, the chip tray 1 is interference fit with the outer shell 11, the chip tray 1 comprises accommodating cavities 102 located on both sides, the accommodating cavities 102 can be used to hold chip iron, and a weight sensing device (not shown) is arranged at the bottom of the chip tray 1, when the chip iron in the chip tray exceeds the limit value, a signal is released to cut off the power supply.

[0018] A parking area 101 is provided in the middle of the iron chip tray 1 . The parking area 101 is a groove with an opening at one end, and the opening is a passage for the second rotating arm 9 to enter and exit.

[0019] The parking area 101 is located between the two accommodating cavities 102, a height adjustment device is provided above the bottom shell 7, an iron chip adsorption device 20 fixedly connected to the height adjustment device is provided above the iron chip tray 1, the height adjustment device passes through a through hole 111 on the outer shell 11, the iron chip adsorption device 20 includes a rotating block 10, the rotating block 10 corresponds to the center of the parking area 101, a first stepper motor 12 for driving its rotation is provided above the rotating block 10, a circular hole 112 is provided on the outer shell 11 corresponding to the position of the first stepper motor 12, the shaft of the first stepper motor 12 passes through the circular hole 112 and is connected to the rotating block 10, and the shaft of the first stepper motor 12 can move up and down in the circular hole 112.

[0020] The rotating block 10 includes a first rotating arm 21 disposed at the lower part thereof. A second rotating arm 9 is disposed below the first rotating arm 21 . The second rotating arm 9 is driven by a second stepping motor 13 . An electromagnet 8 is disposed on a side of the second rotating arm 9 away from the first rotating arm 21 .

[0021] like Figure 3 As shown, when the present invention is in a resting state, the first rotating arm 21 rotates to be parallel to the width section 1012, and the second rotating arm 9 rotates to above the parking area 101, and the two electromagnets 8 are brought into contact with each other.

[0022] like Figure 4As shown, when the present invention is in working state, the first stepper motor 12 drives the rotating block 10 to rotate 90° clockwise, so that the first rotating arm 21 rotates to be parallel to the position of the length section 1011 and then stops, and the second stepper motor 13 on the right side drives the second rotating arm 9 to rotate counterclockwise to the working position at the same time. When the second rotating arm 9 rotates to be collinear with the first rotating arm 21 (i.e., the working position) and then stops, the height adjustment device drives the rotating block 10 to move downward, so that the electromagnet 8 on the right side is close to the ground and then powered on to enter the working state; when the electromagnet 8 on the right side absorbs iron filings to a certain amount, the height adjustment device drives the rotating block 10 to move upward, and at the same time the second stepper motor 13 on the right side drives the second rotating arm 9 to rotate clockwise to the release position. When When the electromagnet 8 on the right side moves to the top of the accommodating chamber 102 (i.e., the release position), the power supply is cut off, and the iron filings fall into the accommodating chamber 102; the second stepper motor 13 on the right side drives the second rotating arm 9 to rotate counterclockwise to the working position, and the height adjustment device drives the rotating block 10 to move downward so that the electromagnet 8 on the right side is close to the ground and then powered on to enter the working state; when the electromagnet 8 on the right side absorbs the iron filings to a certain amount, the height adjustment device drives the rotating block 10 to move upward, and at the same time, the second stepper motor 13 on the right side drives the second rotating arm 9 to rotate counterclockwise to the release position. When the electromagnet 8 on the right side moves to the top of the accommodating chamber 102 (i.e., the release position), the power supply is cut off, and the iron filings fall into the accommodating chamber 102, completing a cycle of operation.

[0023] On the other side of the rotating block 10, another set of first rotating arm 21, second rotating arm 9, second stepper motor 13 and electromagnet 8 are provided as backup devices. When the main electromagnet fails, the first stepper motor 12 rotates in the opposite direction to activate the backup device.

[0024] A bottom plate 4 for sealing is disposed below the bottom shell 7 , and a motion system for moving the iron chip collector device and a battery pack (not shown) for driving the motion system are disposed between the bottom plate 4 and the bottom shell 7 .

[0025] The height adjustment device is a ball screw mechanism 19, and a third stepper motor 14 is provided on the side of the ball screw mechanism 19 away from the bottom shell 7. The ball screw mechanism 19 includes a slide rail 15 fixedly connected to the bottom shell 7, and a screw rod 16 arranged in the slide rail 15. A screw nut is sleeved on the screw rod 16, and a moving block 17 is fixedly connected to the screw nut. Both sides of the moving block 17 are movably connected to the slide rail 15. The left and right sides of the moving block 17 are respectively provided with outwardly extending fixed rods 18, and the fixed rods 18 are fixedly connected to the first stepper motor 12. The forward and reverse rotation of the third stepper motor 14 can drive the screw rod 16 clockwise or counterclockwise, so that the moving block 17 moves up and down, driving the iron chip adsorption device 20 to move up and down. The setting of the third stepper motor 14 can make the up and down movement of the iron chip adsorption device 20 more accurate.

[0026] like Figure 5 , grooves 41 are provided on both sides of the chassis 4, the motion system includes a driving wheel 6, the driving wheel 6 is driven by a motor 5, the motor 5 is fixed in the groove 41, the motion system also includes a universal wheel frame 3 fixed to the chassis 4, a universal wheel 2 is provided below the universal wheel frame 3, the motor 5 drives the driving wheel 6 to rotate, driving the universal wheel to move, so that the device can move freely.

[0027] The parking area 101 includes a length section 1011 and a width section 1012. The total length of the two first rotating arms 21 is smaller than the width section 1012, so that the iron chip adsorption device can move up and down in the parking area 101 when it is in the working position. The total length of the first rotating arm 21 and the second rotating arm 9 is greater than 1 / 2 of the length section 1011, so that the electromagnet 8 can extend out of the iron chip tray 1 to adsorb iron chips.
