Description

Technical Field

[0002] A circulator is a multi-port device in which the transmission of electromagnetic waves circulates in a single direction, and is isolated or counter-rotating in the reverse direction. The principle of the circulator is the anisotropic characteristic of the magnetic field-biased ferrite material. Using the ferrite material as the medium, with a conductive strip structure on it and a constant magnetic field applied, the circulator has a circular characteristic. If the direction of the bias magnetic field is changed, the circulation direction will change. In a base station system, a device with a single-direction circulation characteristic is required. For example, a circulator is commonly used at the output port of a base station power amplifier to isolate signals and prevent signal backflow.

[0032] Refer to Figure 1As shown in the figure, the present invention provides an assembly mechanism for a center conductor and a ferrite, which includes an iron working platform 10, a ferrite discharging mechanism 30, a ferrite manipulator 20, a center conductor discharging assembly 40, a center conductor manipulator 50, and a fixture assembly line 60; the ferrite manipulator 20 and the center conductor manipulator 50 are arranged side by side on the working platform. Both the ferrite manipulator 20 and the center conductor manipulator 50 adopt a three-axis linkage mechanism of the X-axis, Y-axis, and Z-axis. This kind of mechanism is relatively common in the prior art, so the structures of the ferrite manipulator 20 and the center conductor manipulator 50 will not be elaborated in detail in this embodiment. The fixture assembly line 60 is located below the ferrite manipulator 20 and the center conductor manipulator 50. The ferrite discharging mechanism 30 is located at one end of the ferrite manipulator 20. The center conductor discharging assembly 40 is located at one end of the center conductor manipulator 50. The center conductor manipulator 50 is used to transfer the center conductor provided by the center conductor discharging assembly 40 into the fixture of the fixture assembly line 60, and the ferrite manipulator 20 is used to transfer the ferrite into the fixture of the fixture assembly line 60; a return line is also arranged beside the fixture assembly line 60 for realizing the return of the fixture.

[0033] For the ferrite discharging mechanism 30, as Figures 2 to 4 shown, the present invention provides a specific embodiment. The ferrite discharging mechanism 30 includes a discharging turntable 301, a rotating motor 302, a pushing cylinder 303, and a discharging assembly 304; the discharging turntable 301 is fixed on the motor shaft of the rotating motor 302 and rotates driven by the rotating motor 302; a plurality of feeding sleeves 305 are evenly distributed along the circumferential direction of the discharging turntable 301, and a discharging pipe 306 for containing the ferrite is respectively arranged on each feeding sleeve 305; the pushing cylinder 303 is arranged above the discharging turntable 301, and the pushing cylinder 303 is used to push out the ferrite in the feeding sleeve 305; the discharging assembly 304 is located on one side of the discharging turntable 301, and the discharging assembly 304 includes a discharging guide rail 3041 for receiving the ferrite.

[0034] In the above embodiment, a material pipe limiting ring 3011 is fixedly arranged above the discharging turntable 301. The cover material pipe limiting ring 3011 is provided with limiting elastic pieces 3012 having the same number as the discharging pipes 306, and the discharging pipes 306 are stuck in the limiting elastic pieces 3012; a plurality of support columns are arranged between the material pipe limiting ring 3011 and the discharging turntable 301.

[0035] In this embodiment, the discharging assembly 304 includes a discharging motor 3042, a synchronous belt 3043, a synchronous pulley 3044, and a ferrite feeding belt 3045. The discharging motor 3042 is fixed below the discharging guide rail 3041. A driving wheel 3046 is installed on the output shaft of the discharging motor 3042. The synchronous belt 3043 is sleeved between the driving wheel 3046 and the synchronous pulley 3044. The ferrite feeding belt 3045 is rotatably installed inside the discharging guide rail 3041. A transmission shaft is provided on the synchronous pulley 3044, and this transmission shaft is used to drive the ferrite feeding belt 3045 to rotate.

[0036] In addition, a positioning column 3051 is arranged inside the feeding sleeve 305. A limiting block 3052 connected thereto is arranged below the positioning column 3051. The limiting block 3052 drives the positioning column 3051 to move up and down inside the feeding sleeve 305. A telescopic spring is sleeved on the positioning column 3051, and this telescopic spring is used to keep the positioning column 3051 in a protruding state. A positioning assembly 307 is arranged below the discharging turntable 301. This positioning assembly 307 includes a positioning cylinder 3071 and a lifting clamp seat 3072. The lifting clamp seat 3072 is connected to the cylinder rod of the positioning cylinder 3071. A slot for accommodating the limiting block 3052 is arranged inside the lifting clamp seat 3072. The positioning cylinder 3071 is used to pull the limiting block 3052 downward.

[0037] Combined with the above structure, the working process of the present invention will be described in detail. First, a plurality of ferrites are arranged vertically in the discharging pipe 306, and the ferrites will move downward under the action of their own gravity. The limiting elastic piece 3012 keeps the discharging pipe 306 in a detachable state. When the feeding of the ferrites in the discharging pipe 306 is completed, the discharging pipe 306 can be replaced. During discharging, the lowermost ferrite in the discharging pipe 306 is located above the positioning column 3051 under the action of gravity and is positioned by the positioning column 3051. When discharging is required, the positioning cylinder 3071 drives the lifting clamp seat 3072 to move downward, pulls the limiting block 3052, and drives the positioning column 3051 to retract. Since the slot of the lifting clamp seat 3072 is in a penetrating state, when the discharging turntable 301 rotates, the limiting block 3052 passes through the slot, and the pulling of a plurality of limiting blocks 3052 can be realized.

[0038] After the positioning column 3051 retracts, the cylinder rod of the material clamping cylinder 309 extends, and the cylinder rod of the material pushing cylinder 303 extends to push the ferrite onto the ferrite feeding belt 3045 of the discharging assembly 304, and the ferrite is driven to translate by the ferrite feeding belt 3045. In this embodiment,

[0039] The discharging turntable 301 is arrayed with pushing chute grooves equal in number to the feeding sleeves 305. In this embodiment, four feeding sleeves 305 are evenly distributed on the discharging turntable 301. A sliding pushing slider 3014 and a pushing rod 3015 are arranged in the pushing chute groove 3013. One end of the pushing rod 3015 is connected to the pushing slider 3014, and a pushing nut is fixedly installed on the pushing slider 3014. The top end of the cylinder rod of the pushing cylinder 303 is connected to a pushing clamping part 3031, and the pushing clamping part 3031 has an opening. When the pushing chute groove 3013 is docked with the discharging assembly, the pushing nut is located within the opening of the pushing clamping part 3031. When the cylinder of the pushing cylinder 303 extends, through the cooperation of the pushing clamping part and the pushing nut, the pushing slider 3014 and the discharging rod 3015 are driven to move together, and the discharging rod 3015 pushes the ferrite onto the ferrite conveying belt 3045, realizing the individual feeding of the ferrite. The present invention can realize the automatic discharging of the ferrite, improve the discharging efficiency, reduce the manual labor intensity, and has a high discharging efficiency; the discharging pipe 306 can be replaced after the feeding is completed, and this mechanism can operate continuously, greatly improving the discharging efficiency.

[0040] Combined with Figure 1 、 Figure 5 As shown, for the central conductor discharging assembly 40, the present invention provides a specific embodiment. The central conductor discharging assembly 40 includes a central conductor turntable 401, a central conductor motor 402, a central conductor material pipe 403, and a central conductor feeding assembly 404. Two central conductor turntables 401 are arranged vertically opposite to each other. The central conductor material pipes 403 are evenly distributed along the circumferential direction of the central conductor turntable 401 and are detachably fixed on the two central conductor turntables 401. In this embodiment, the detachable fixation of the central conductor material pipe 403 is realized through an elastic snap. The central conductor turntable 401 is connected to the motor shaft of the central conductor motor 402 and rotates driven by the central conductor motor 402. The central conductor feeding assembly 404 is arranged on one side of the central conductor turntable 401. The central conductor feeding assembly 404 includes a feeding push rod 4041. The feeding push rod 4041 extends into the central conductor material pipe 403 and pushes the central conductor in the central conductor material pipe 403 from bottom to top. The central conductor manipulator 50 is used to suck the central conductor from the top of the central conductor material pipe 403 and transfer it into the fixture on the fixture assembly line 60.

[0041] Further, the central conductor feeding assembly 404 further includes a feeding motor 4042, a rotating lead screw 4043, and a lifting slider 4044; the rotating lead screw 4043 is connected to the motor shaft of the feeding motor 4042, and a lead screw nut is provided on the lifting slider 4044, and this lead screw nut is adapted to the rotating lead screw 4043. The top end of the feeding push rod 4041 is fixed on the lifting slider 4044. By the rotation of the feeding motor 4042, the lifting slider 4044 is driven to perform a lifting motion, thereby driving the feeding push rod 4041 to perform a lifting motion. The central conductor feeding assembly 404 further includes a lifting guide rod 4045. The feeding motor 4042 is fixed on a motor fixing plate 4046. The bottom end of the rotating lead screw 4043 is rotatably installed on a limiting plate 4047. Both ends of the lifting guide rod 4045 are respectively fixed on the motor fixing plate 4046 and the limiting plate 4047. A guide sleeve 4048 adapted to the lifting guide rail is provided on the lifting slider 4044. Through the design of this structure, when the feeding motor 4042 rotates, the cooperation of the rotating lead screw 4043 and the lifting slider 4044 enables the feeding push rod to perform a lifting motion. When moving upward, the central conductor in the central conductor material tube can be ejected, and through the cooperation of the central conductor manipulator, the automatic feeding of the central conductor is completed; this central conductor discharging assembly 40 with such a structure can feed the central conductors one by one from top to bottom. After one central conductor material tube is loaded, only its replacement is required, and uninterrupted feeding can be achieved, improving the feeding efficiency and assembly efficiency, and having high feeding precision and small deviation after the central conductor is fed.

[0042] In summary, an assembly mechanism for a central conductor and a ferrite of the present invention can realize the automatic discharging and feeding of the ferrite and the central conductor. The whole process does not require manual participation, and only the feeding sleeve and the central conductor material tube need to be replaced; moreover, the feeding efficiency is high, the precision is high, and the labor intensity of workers is reduced.
