Description

[0002] A circulator is a multi-port device in which the electromagnetic wave propagates in a single direction and is isolated or counter-rotating in the opposite direction.

A return line 211 is also provided on the side of the fixture assembly line 210 to facilitate the return of the fixture.

[0028] like Figures 2 to 4As shown, for the strong magnetic sheet discharging mechanism 30, the present invention provides a specific embodiment, in which the strong magnetic sheet 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 by the driving of the rotating motor 302; the discharging turntable 301 is evenly distributed with a plurality of loading sleeves 305 along the circumferential direction, and each loading sleeve 305 is respectively provided with a discharging pipe 306 for holding a strong magnetic sheet; the pushing cylinder 303 is arranged above the discharging turntable 301, and the pushing cylinder 303 is used to push out the strong magnetic sheet in the loading 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 strong magnetic sheet.

[0029] In the above embodiment, a material tube limiting ring 3011 is fixedly provided above the discharge turntable 301, and the material tube limiting ring 3011 is provided with limiting spring pieces 3012 of the same number as the discharge tubes 306, and the discharge tubes 306 are stuck in the limiting spring pieces 3012; a plurality of support columns are provided between the material tube limiting ring 3011 and the discharge turntable 301.

[0030] In this embodiment, Figure 3 As shown, the discharging assembly 304 includes a discharging motor 3042, a synchronous belt 3043, a synchronous wheel 3044 and a strong magnetic sheet material transfer belt 3045; the discharging motor 3042 is fixed below the discharging guide rail 3041, and 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 wheel 3044. The strong magnetic sheet material transfer belt 3045 is rotatably installed inside the discharging guide rail 3041, and a transmission shaft is provided on the synchronous wheel 3044, which is used to drive the strong magnetic sheet material transfer belt 3045 to rotate.

[0031] In addition, a discharge pressing sheet 3047 is provided above the discharge guide rail 3041 for limiting the position of the strong magnetic sheet; a strong magnetic sheet slide 3048 is provided at the end of the discharge guide rail 3041, and the slide is inclined. A strong magnetic sheet holder 3049 is provided at the end of the strong magnetic sheet slide 3048, and a slot for clamping the strong magnetic sheet is provided on the strong magnetic sheet holder 3049, and a strong magnetic sheet lifting cylinder 3050 is provided below the strong magnetic sheet holder 3049, and the cylinder rod of the strong magnetic sheet lifting cylinder 3050 is connected to a push rod, and the strong magnetic sheet is lifted by the push rod. The design of this mechanism allows the strong magnetic sheets to be arranged one by one in the slot, so that the strong magnetic sheets can be fed one by one. At the same time, due to the existence of the strong magnetic sheet lifting cylinder, the strong magnetic sheets can be cached.

[0032] like Figure 4As shown, a positioning column 3051 is arranged inside the feeding sleeve 305, and a limit block 3052 connected to the positioning column 3051 is arranged below the positioning column 3051. The limit block 3052 drives the positioning column 3051 to move up and down in the feeding sleeve 305. A telescopic spring is sleeved on the positioning column 3051, and the telescopic spring is used to keep the positioning column 3051 in an extended state. A positioning assembly 307 is arranged below the discharging turntable 301, and the positioning assembly 307 includes a positioning cylinder 3071 and a lifting seat 3072. The lifting seat 3072 is connected to the cylinder rod of the positioning cylinder 3071. A slot for accommodating the limit block 3052 is arranged inside the lifting seat 3072, and the positioning cylinder 3071 is used to pull the limit block 3052 to move downward.

[0033] Combined with the above structure, the working process of the present invention is described in detail. First, multiple strong magnetic sheets are arranged in the vertical direction in the discharge pipe 306, and the strong magnetic sheets will move downward under the action of their own gravity. The limiting spring sheet 3012 keeps the discharge pipe 306 in a detachable state. When the strong magnetic sheets in the discharge pipe 306 are loaded, the discharge pipe 306 can be replaced. During discharge, the strong magnetic sheet at the bottom of the discharge pipe 306 is located above the positioning column 3051 under the action of gravity, and the positioning is achieved through the positioning column 3051. When discharge is required, the positioning cylinder 3071 drives the lifting seat 3072 to move downward, pulls the limiting block 3052, and drives the positioning column 3051 to retract. Since the card slot of the lifting seat 3072 is in a through state, when the discharge turntable 301 rotates, the limiting block 3052 passes through the card slot, which can achieve the pulling of multiple limiting blocks 3052.

[0034] When the positioning column 3051 is retracted, the cylinder rod of the clamping cylinder 309 extends, and the cylinder rod of the pushing cylinder 303 extends, pushing the strong magnetic sheet onto the strong magnetic sheet conveying belt 3045 of the discharge assembly 304, and the strong magnetic sheet is driven to move horizontally by the strong magnetic sheet conveying belt 3045. In this embodiment,

[0035] The discharge turntable 301 is arrayed with push chutes 3013, the same number as the loading sleeves 305. In the present embodiment, four loading sleeves 305 are evenly distributed on the discharge turntable 301; a sliding push slider 3014 and a push rod 3015 are provided in the push chute 3013, one end of the push rod 3015 is connected to the push slider 3014, and a push nut is fixedly installed on the push slider 3014; the top end of the cylinder rod of the push cylinder 303 is connected to a push clamp 3031, and the push clamp 3031 has an opening, and when the push chute 3013 is docked with the discharge assembly, the push nut is located in the opening of the push clamp 3031. When the cylinder of the push cylinder 303 extends, the push clamp and the push nut cooperate to drive the push slider 3014 and the ejector rod 3015 to move together, and the ejector rod 3015 pushes the strong magnetic sheet to the strong magnetic sheet conveying belt 3045, so as to realize the loading of the strong magnetic sheets one by one. The present invention can realize the automatic discharge of the strong magnetic sheets, improve the discharge efficiency, reduce the labor intensity, and has high discharge efficiency; the discharge pipe 306 can be replaced after the loading is completed, and the mechanism can run uninterruptedly, which greatly improves the discharge efficiency.

[0036] In the above-mentioned embodiment, the strong magnetic sheet manipulator 310 and the isolated uniform magnetic sheet manipulator 201 both adopt the structure of X-axis, Y-axis and Z-axis, which is more common in the prior art, so the structure is not described in detail in this embodiment. In addition, the fixture assembly line and the return line generally include a conveyor belt with a conveying function, which is also very mature in the prior art and is not described in detail in this embodiment.

[0037] After the strong magnetic sheet and the isolated uniform magnetic sheet are transferred to the jig of the jig assembly line 210, they are assembled in the jig, so the jig assembly line 210 needs to position the jig. Figure 1 , Figure 5As shown, a jig lifting assembly 207 is provided below the jig assembly line 210. In this embodiment, the jig lifting assembly 207 includes a lifting cylinder 2071, a lifting block 2072, a lifting guide column 2073, a lifting support plate 2074, a jig limit block 2075 and a jig clamping cylinder 2076; two lifting support plates 2074 are arranged opposite to each other, the lifting block 2072 is located between the two lifting support plates 2074, and the lifting block 2072 is connected to the lifting cylinder 2071. The cylinder rod is connected, and a jig limit block 2075 is fixed on the top of the jacking support plate 2074. After the jacking cylinder 2071 lifts the lifting block 2072, the jig is pressed on the jig limit block 2075; the lifting guide column 2073 is fixed on the jacking support plate 2074 in the vertical direction, and the two ends of the lifting block 2072 are slidably installed on the lifting guide column 2073. The jig pressing cylinder 2076 is fixed on one side of the jig limit block 2075 to realize the clamping of the jig. This structural design facilitates the positioning of the jig, so as to facilitate the assembly of the isolation and uniform magnetic sheet and the strong magnetic sheet.

[0038] The present invention can realize automatic loading of strong magnetic sheets, and can also realize automatic loading of isolated and uniform magnetic sheets, thereby improving assembly efficiency and reducing manual labor intensity; and the strong magnetic sheets can be automatically discharged, thereby improving the discharge efficiency, and the discharge efficiency is high; the discharge pipe can be replaced after the loading is completed, and the mechanism can operate uninterruptedly, thereby greatly improving the discharge efficiency.
