[0021] Reference Figure 1-7 The figure shows a preferred embodiment of the present invention.

[0022] The deflection positioning method of the electric stapler includes a control board 1, a motor assembly 2, a transmission member 3 and a photoelectric sensor 4, wherein the photoelectric sensor 4 is electrically connected to the control board 1, the motor assembly 2 is used to drive the transmission member 3 to move forward or backward, and the transmission member 3 is used to push the jaws to deflect; the deflection positioning steps are as follows: (1) The control board 1 receives the carrier signal, analyzes the carrier signal, and outputs a control instruction to drive the motor assembly 2; (2) The control board 1 initializes the positions of the motor assembly 2 and the transmission member 3 respectively; (3) Entering the normal working state, the control board 1 outputs instructions to control the jaws to deflect to the left or right; (4) The transmission member 3 has a left notch, a middle notch and a right notch. When the left notch triggers the photoelectric sensor 4, the jaws deflect to the left to the extreme position, deflect to the left to the position, and stop responding to the left deflection instruction; when the middle notch triggers the photoelectric sensor 4, the transmission member 3 moves to the middle position, and the control board 1 controls the motor assembly 2 to be in a stopped state until the deflection instruction is received again; when the right notch triggers the photoelectric sensor 4, the jaws deflect to the right to the extreme position, deflect to the right to the position, and stop responding to the right deflection instruction.

[0023] In the above-mentioned electric stapler deflection positioning method, when the electric stapler is adjusting its angle, the control board 1 first initializes the position of the motor assembly 2 and the transmission member 3 respectively, so that the jaws are in a middle non-deflected state. Based on the operation requirements, the control board 1 outputs instructions to control the jaws to deflect to the left or to the right, so as to realize the normal operation of the electric stapler. At the same time, during the deflection of the jaws, based on the respective triggering of the photoelectric sensor 4 and the left notch, the middle notch and the right notch, the deflection of the jaws is positioned, and precise positioning is achieved, thereby making the electric stapler more stable and reliable, and improving the operability of the electric stapler, thereby improving the safety of the operation.

[0024] The electric stapler deflection positioning method includes a current monitoring module. In step (2), during the initialization process, when the transmission member 3 is driven to the front and rear limit positions and is blocked, the current monitoring module detects abnormal current, and the control board 1 controls the motor assembly 2 to reverse.

[0025] In this way, based on the abnormal current fed back by the current monitoring module, the control board 1 controls the motor assembly 2 to reverse, thereby facilitating the initialization of the motor assembly 2 and the transmission member 3 .

[0026] Specifically, when the transmission member 3 is in the front limit position and is blocked, the jaw is in the left deflection limit position, and the control board 1 controls the motor assembly 2 to reverse, controls the jaw to deflect to the right until it is in the initialization state, that is, the non-deflection state, and controls the transmission member 3 to retreat to the middle, thereby completing the initialization of the motor assembly 2 and the transmission member 3.

[0027] When the transmission member 3 is in the rear limit position and is blocked, the jaws are in the right deflection limit position, and the control board 1 controls the motor assembly 2 to reverse, controls the jaws to deflect to the left until it is in the initialization state, that is, the non-deflection state, and controls the transmission member 3 to move forward to the middle, completing the initialization of the motor assembly 2 and the transmission member 3.

[0028] In step (2), during the initialization process, when the middle notch triggers the photoelectric sensor 4, the jaws are at the center position under the traction of the transmission member 3, and the control board 1 stops driving the motor assembly 2, thereby achieving the initialization of the motor assembly 2.

[0029] The initialization of the motor assembly 2 and the transmission member 3 is completed to improve the deflection positioning accuracy of the jaws.

[0030] In step (2), the electric stapler deflection positioning method includes a decoding module, the decoding module is used to analyze the carrier signal, and the decoding module is electrically connected to the control board 1.

[0033] Since the rotating head 72 is rotatably connected to the shell 71 by 360 degrees, it is not convenient to use multi-line transmission for the front and rear electrical connections.

In this way, the layer-by-layer transmission of the driving force is realized, which facilitates the control of the size of the driving force.

[0037] The first reduction gear set includes a first drive gear, and the medium reduction gear set includes a medium-large gear and a medium-small gear. The number of teeth of the medium-large gear is greater than that of the small and medium gears, and the medium-large gear and the small and medium gears are arranged to rotate coaxially. The first drive gear is meshed with the medium-large gear, and the number of teeth of the first drive gear is less than that of the medium-large gear. In this way, the deceleration of the driving force is achieved.

[0065] The photoelectric sensor 4 can also be replaced by a touch switch.

[0066] The motor assembly includes a DC motor 21, a reduction box 22 and a motor shaft 23.

The worm 221 is axially connected to the DC motor 21, and the worm is used to drive the turbine to rotate. The reduction gear set 222 is meshed with the worm wheel, and the worm wheel and the worm 221 cooperate to switch the axial driving force output to the radial driving force output. In this way, it is convenient to realize the layout of the motor assembly of the stapler within the effective space, and at the same time, realize the switching of the driving force output direction, effectively save space, and improve the coordination effect between the DC motor 21, the reduction box 22 and the motor shaft 23.

[0067] The multiple reduction gear sets 222 include a first reduction gear set, multiple middle reduction gear sets and a tail reduction gear set. The middle reduction gear sets are arranged in a row, and the middle reduction gear sets are meshed in sequence. The first reduction gear set is meshed with one of the middle reduction gear sets and the worm 221, and the tail reduction gear set is meshed with one of the middle reduction gear sets 222 and the motor shaft 23. In this way, the layer-by-layer transmission of the driving force is realized, which facilitates the control of the size of the driving force.

[0068] The first reduction gear set includes a first drive gear, and the medium reduction gear set includes a medium-large gear and a medium-small gear. The number of teeth of the medium-large gear is greater than that of the small and medium gears, and the medium-large gear and the small and medium gears are arranged to rotate coaxially. The first drive gear is meshed with the medium-large gear, and the number of teeth of the first drive gear is less than that of the medium-large gear. In this way, the deceleration of the driving force is achieved.

[0069] The tail reduction gear set includes a tail drive gear, and the medium reduction gear set includes a medium-large gear and a small and medium gear. The number of teeth of the medium-large gear is greater than that of the small and medium gears, and the medium-large gear and the small and medium gears are arranged to rotate coaxially; the tail drive gear is meshed with the small and medium gears, and the number of teeth of the tail drive gear is greater than that of the small and medium gears; in this way, when the small and medium gears transmit the driving force to the tail drive gear, they are arranged to reduce speed, which has a deceleration effect on the tail reduction gear set, so that the driving force transmitted to the motor shaft 23 by the tail reduction gear set is more stable.

[0070] Furthermore, the various intermediate reduction gear sets are arranged in layers to achieve multi-level reduction, thereby improving the output stability of the driving force and facilitating the control of the driving force output.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
