[0027] The present invention will be described in detail below in conjunction with specific embodiments and the accompanying drawings of the specification.

[0028] Please refer to Figures 1-7 As shown, the present invention relates to an automatic glue cutting and pasting device for a carbon brush arm, which is characterized in that it includes a feeding mechanism 5, a material grabbing mechanism 1, a glue cutting mechanism 2, and a glue sucking and pasting mechanism 3;

[0029] Wherein, the feeding mechanism 5 includes a circular vibration device 51 and a linear vibration device 52, which sort and discharge the carbon brush arms 115 according to production requirements. The carbon brush arms 115 are discharged from the circular vibration device 51 to the linear vibration device 52. A sensor 53 for stopping vibration when the material is full is installed above the linear vibration device 52. When the material storage in the material channel of the linear vibration device 52 reaches the full material position, the circular vibration device 51 stops vibrating, reducing noise pollution and preventing the carbon brush arms 115 from being damaged, deformed or jammed due to long-term vibration. The linear vibration device 52 smoothly supplies the carbon brush arms 115 to the feeding waiting material station;

[0033] The working process is as follows:

[0034] The carbon brush arms 115 are sorted and arranged to the waiting material station of the carbon brush arms 115 by the special feeding mechanism 5 as required. The carbon brush arm 115 in-place sensor detects that the material is in place, and the carbon brush arm 115 feeding mechanism 5 operates. The manipulator assembly picks up the carbon brush arm 115 at the waiting material station and sends it to the gluing station; on the other side, in the glue cutting mechanism 2, the first glue cutting driving device drives the glue strip in the feeding track 25 to move towards the glue strip waiting material groove 22, and the second glue cutting driving device drives the glue cutting component to move towards the connection of the feeding track 25 and the glue strip waiting material groove 22 and finally cuts the glue strip; the glue sucking component in the glue sucking and gluing mechanism 3 sucks the processed glue strip in the glue strip waiting material groove 22.

[0058] Please refer to Figures 1-7 as shown, the specific working process of the present invention:

[0059] Step 1: The carbon brush arm 115 is discharged from the circular vibrating device to the linear vibrating device, and the linear vibrating device sends the carbon brush arm 115 to the material waiting station. When the material full stop vibration sensor detects that the material channel of the linear vibrating device is full to the full material position, the circular vibrating device is controlled to stop vibrating;

[0060] Step 2: The first baffle driving device 122 drives the first baffle 124 to stop the carbon brush arm 115 in the material waiting station;

[0061] Step 3: When the material arrival sensor 114 above the material waiting station detects that the carbon brush arm 115 is in place, the second baffle driving device 123 drives the second baffle 116 and stops the carbon brush arm 115 outside the material waiting station;

[0062] Step 4: The manipulator grabs the carbon brush arm 115 in the material waiting station. At the same time, the second baffle driving device 123 drives the first baffle 124 to retract and not block the carbon brush arm 115;

[0063] Step 5: The first pushing cylinder 119 drives the manipulator to drive the carbon brush arm 115 to move from the material waiting station to the gluing station;

[0064] Step 6: The support plate driving device 121 drives the gluing fixed support plate 120 to move to the gluing station to support the back of the gluing position of the carbon brush arm 115;

[0065] Step 7: The glue feeding motor 29 drives the feeding roller 24 to drive the rubber strip in the feeding track 25 to move towards the rubber strip waiting groove 22;

[0066] Step 8: When the rubber strip enters the rubber strip waiting bin 22 and triggers the rubber strip in-place sensor 26, the rubber strip in-place sensor 26 sends an electrical signal to the second rubber cutting driving device. After receiving the electrical signal, the second rubber cutting driving device drives the blade 27 aligned at the connection of the feeding track 25 and the rubber strip waiting bin 22 to move towards the position of the rubber strip and finally cuts the rubber strip.

[0067] Step 9: The rubber strip suction assembly sucks the processed rubber strip located in the rubber strip waiting bin 22. Through the cooperation between the first linear module and the second linear module, the processed rubber strip is moved from the waiting bin to the rubber sticking station, and through the cooperation between the first linear module and the second linear module, the rubber strip is driven to be attached to the designated position of the carbon brush arm 115, so that the shock-absorbing rubber and the carbon brush arm 115 are attached into one body, realizing automatic rubber sticking.

[0068] Step 10: The defective product detection sensor 113 detects the carbon brush arm 115. When the defective product detection sensor 113 detects that the carbon brush arm 115 is a qualified product, the carbon brush arm 115 will directly fall onto the qualified product flow channel 44 and then be conveyed to the qualified product box through the qualified product flow channel 44. When the defective product detection sensor 113 detects that the carbon brush arm 115 is a defective product, the driving part drives the first defective product flow channel 45 and the qualified product flow channel 44 to move, so that the first defective product flow channel 45 is communicated with the defective product hole 421, and the carbon brush arm 115 will fall into the defective product box 47 and then fall into the defective product box 47 from the defective product hole 421. When the defective product detection sensor 113 detects that the carbon brush arm 115 becomes a qualified product, the driving part drives the first defective product flow channel 45 and the qualified product flow channel 44 to move, so that the first defective product flow channel 45 returns to its original position.

[0069] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
