Detailed Implementation

[0014] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] This embodiment proposes an electric lifting drive mechanism for a conveying system, such as... Figure 1 As shown, it includes a drive module 1, a lifting module 2, a positioning bracket 3, and a control module 4, as follows: Figure 2 As shown, the drive module 1 includes a DC motor 101 and a motor driver 102. The DC motor 101 is controlled by the motor driver 102 to rotate forward, rotate in reverse, or stop.

[0016] like Figure 2 Figure 3As shown, the lifting module 2 is responsible for converting the rotational motion into linear lifting motion. All components work together to achieve smooth lifting. The lifting module 2 includes a guide rail connecting plate 201, a guide rail 202, a slider 203, a lifting plate 204, a rotating arm 205, and a photoelectric sensor plate 206. The DC motor 101 is fixed to the front end of the guide rail connecting plate 201. The positioning bracket 3 is fixedly connected to the front end of the guide rail connecting plate 201. The motor driver 102 is fixed to one side of the positioning bracket 3. One end of the rotating arm 205 is fixedly connected to the output shaft of the DC motor 101.

[0017] like Figure 4 As shown, the positioning bracket 3 serves as a support component for the drive module 1. It is made of high-strength sheet metal material through laser cutting, bending and welding processes. The connecting surface of the positioning bracket 3 is provided with holes of various specifications for connection with other components.

[0018] The lower part of the lifting plate 204 is provided with a waist-shaped hole 207 along the horizontal direction. A bearing follower 208 that slides horizontally is provided in the waist-shaped hole 207. The other end of the rotating arm 205 is hinged to the bearing follower 208. The lifting plate 204 and the guide rail connecting plate 201 are connected vertically by the cooperation of the slider 203 and the guide rail 202.

[0019] like Figure 2 As shown, the control module 4 includes a limit switch 401, a limit bracket 402, an upper slot type photoelectric sensor 403, and a lower slot type photoelectric sensor 404. The limit switch 401 is fixed to the upper part of the lifting plate 204 through the limit bracket 402. The limit switch 401 is used to detect the position of the workpiece. When the conveying roller transports the material to the preset processing station or detection area, the limit switch 401 is triggered and transmits a signal to the control system. After receiving the signal, the control system issues a command to stop the conveying roller and the mechanical equipment operates on the workpiece.

[0020] When the control module 4 sends a start signal, the motor driver 102 receives the signal and converts the external power supply into voltage and current suitable for the DC motor 101. Under the control of the motor driver 102, the DC motor 101 rotates forward or backward, converting electrical energy into rotational mechanical energy. The motor driver 102 supports PWM (Pulse Width Modulation) speed regulation. By changing the duty cycle of the output pulse, the average value of the input voltage of the DC motor 101 is adjusted, thereby realizing stepless adjustment of the speed of the DC motor 101. The speed regulation accuracy can reach ±5%. The rotational motion of the output shaft of the DC motor 101 is directly transmitted to the rotating arm 205, providing power for the lifting action.

[0021] When the work is completed, the limit switch 401 is triggered again, sending a signal that the process is completed to the control system. The conveyor rollers restart, the lifting module is also started simultaneously, the lifting plate 204 descends, and the workpiece passes through and is transported to the next stage.

[0022] The upper slot type photoelectric sensor 403 and the lower slot type photoelectric sensor 404 are combined and fixed as one unit on the rear side of the guide rail connecting plate 201. The photoelectric sensing plate 206 cooperates with the detection slots of the upper slot type photoelectric sensor 403 and the lower slot type photoelectric sensor 404. The upper slot type photoelectric sensor 403, the lower slot type photoelectric sensor 404 and the motor driver 102 are connected in communication.

[0023] The guide rail 202 is fixed vertically to the rear end of the guide rail connecting plate 201. The lifting plate 204 is located on the rear side of the guide rail connecting plate 201. The slider 203 is fixed to the front end of the lifting plate 204. The slider 203 and the guide rail 202 are slidably connected vertically. The front end of the lifting plate 204 is provided with a slider connecting plate 210 vertically. The slider 203 is fixed to the front end of the slider connecting plate 210.

[0024] A support plate 209 is fixedly provided at the bottom end of the guide rail connecting plate 201. The support plate 209 protrudes forward in the horizontal direction. A positioning base plate 301 is bent forward in the horizontal direction at the bottom end of the positioning bracket 3. The positioning base plate 301 and the support plate 209 are fixedly connected by screws. Positioning side plates 302 are bent forward at both ends of the positioning bracket 3. The positioning side plates 302 and the positioning base plate 301 support and fix the motor driver 102.

[0025] The output shaft of DC motor 101 drives the rotating arm 205 to rotate. Since the rotating arm 205 is eccentrically set on the output shaft of DC motor 101, as the output shaft rotates, the bearing follower 208 rolls and contacts in the waist-shaped hole 207 at the bottom of the lifting plate 204 and generates thrust, pushing the lifting plate 204 to move up and down along the guide rail. When DC motor 101 rotates forward, it drives the lifting plate 204 to rise. When DC motor 101 rotates in reverse, it drives the lifting plate 204 to fall. The photoelectric sensor plate 206 moves synchronously with the lifting plate 204, providing a position detection signal for the limit switch 401.

[0026] During the lifting process, the photoelectric sensor plate moves with the lifting plate 204. When it rises to the set height, the photoelectric sensor plate 204 inserts into the detection slot of the upper slot type photoelectric sensor 403. The upper slot type photoelectric sensor 403 detects the position signal through light signal blocking and sends a signal to the motor driver 102. The motor driver 102 controls the DC motor 101 to stop, realizing non-contact precise positioning. When descending, the photoelectric sensor plate 204 inserts into the detection slot of the lower slot type photoelectric sensor 404, triggering the DC motor 101 to stop.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
