DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1, reference Figure 1-Figure 2 , is the first embodiment of the present invention, which provides a metallized capacitor visual inspection device, which includes a detection conveyor belt 1 for conveying a metallized capacitor a to be inspected, a placement box 2 arranged on the detection conveyor belt 1, a plurality of grooves arranged on the placement box 2 for placing the metallized capacitor a to be inspected, the capacitor pins in the grooves face upward to prevent the pins from being squeezed and deformed, a lifting unit 3 arranged above the detection conveyor belt 1, for lifting the metallized capacitor a on the placement box 2 to facilitate appearance inspection, a visual inspection unit 4 arranged on the lifting unit 3, for performing appearance inspection on the lifted metallized capacitor a and removing unqualified metallized capacitors a from the lifting unit 3, and a collection conveyor belt 5 arranged on one side of the lifting unit 3, for collecting and conveying qualified metallized capacitors a; The lifting unit 3 includes a fixed frame 31 arranged above the detection conveyor belt 1, the fixed frame 31 is fixedly arranged in the detection workshop, and plays a supporting and fixing role; a roller 32 arranged on the fixed frame 31 is used for rotation; a separation conveyor belt 33 arranged on the roller 32 is used to drive the separation conveyor belt 33 to transmit when the roller 32 rotates, and to transmit the metallized capacitor a on the separation conveyor belt 33; a movable support assembly 34 arranged on the roller 32 is used to support the separation conveyor belt 33 through the roller 32, and at the same time, when the shape of the separation conveyor belt 33 changes, the separation conveyor belt 33 is movably supported; and an active assembly 35 arranged on the active support assembly 34 is used to control the shape of the separation conveyor belt 33 to change through the roller 32 and the active support assembly 34, so as to drive the metallized capacitor a to leave the placement box 2, and at the same time drive the metallized capacitor a on the separation conveyor belt 33 to approach the visual inspection unit 4, and perform appearance inspection on the metallized capacitor a.

[0030] In summary, when the device is running, first, the metallized capacitor a is placed on the placement box 2 through the groove, so that the pins of the metallized capacitor a face upwards, and the placement box 2 filled with the metallized capacitor a is placed on the detection conveyor belt 1. At this time, the detection conveyor belt 1 drives the placement box 2 to be transported in the direction close to the separation conveyor belt 33. When the placement box 2 follows the detection conveyor belt 1 to move to the bottom of the separation conveyor belt 33, the movable component 35 is started, and the width of the rectangle formed by the separation conveyor belt 33 is increased and the length is reduced through the cooperation of the movable support component 34. At this time, the bottom of the separation conveyor belt 33, that is, the wide side of the rectangle formed by the separation conveyor belt 33 is close to the placement box 2, and the metallized capacitor a on the placement box 2 is adsorbed by the pins of the metallized capacitor a. At this time, the separation conveyor belt 33 is driven by the movable component 35 and the movable support component 34 to restore its original shape. At this time, the separation conveyor belt 33 drives the metallized capacitor a to leave the placement box 2, and the main part of the metallized capacitor a is fully exposed to the outside; At this time, the separation conveyor belt 33 drives the metallized capacitor a through the visual inspection unit 4. At this time, the visual inspection unit 4 performs visual inspection on the metallized capacitor a on the separation conveyor belt 33, and knocks down the unqualified metallized capacitor a. Since the inspection conveyor belt 1 and the separation conveyor belt 33 move synchronously, the unqualified metallized capacitor a that falls at this time just falls on the placement box 2, which is convenient for recycling. At this time, the inspected metallized capacitor a is transported to the collection conveyor belt 5 through the separation conveyor belt 33. At this time, the collection conveyor belt 5 transports the qualified metallized capacitor a to the next process.

[0031] Example 2, reference Figure 1-Figure 7 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: the metallized capacitor a is lifted up, so that the main body of the metallized capacitor a is fully exposed to the air, which is convenient for the visual inspection unit 4 to inspect. Compared with the embodiment 1, further, the separation conveyor belt 33 is provided with four groups, which are distributed in a rectangular shape; The roller 32 is provided with a support block 321 for supporting the roller 32. The fixed frame 31 is provided with a support groove 311 for matching the upper support block 321. The support groove 311 is horizontally arranged for matching the roller 32 to move back and forth on the support groove 311. The fixing frame 31 is provided with a movable groove 312 which matches the lower supporting block 321 . The movable groove 312 is arranged obliquely. The movable groove 312 is used to control the moving track of the supporting block 321 when the length and width of the rectangle formed by the separation conveyor belt 33 change.

[0032] Among them, a magnet 331 is provided on the separation conveyor belt 33, which is used to attract the pins of the metallized capacitor a. The pins of the metallized capacitor a contain magnetic materials, such as ferrite, etc. These materials are added during the manufacturing process of the metallized capacitor a to stabilize the characteristics of the metallized capacitor a in the high-frequency circuit and prevent the pin from deforming. When the magnet 331 approaches the pins of the metallized capacitor a, the magnetic lines of force will pass through the pins, and the magnetic material in the pins will feel the effect of the magnetic force, thereby being attracted by the magnet 331.

[0033] Among them, the movable support assembly 34 includes a first connecting block 341 arranged on the roller 32 and a second connecting block 342 arranged on another group of rollers 32 below. The first connecting block 341 and the second connecting block 342 are used to connect the upper and lower groups of rollers 32 to play a supporting and connecting role; a plug-in block 343 arranged on the first connecting block 341 and a plug-in groove 344 arranged on the second connecting block 342, which are used to cooperate with the plug-in block 343 to slide up and down, and cooperate with the changes in the length and width of the rectangle formed by the separation conveyor belt 33; and a support spring 345 arranged in the plug-in groove 344, which is used to deform with the up and down sliding of the plug-in block 343, provide stable support for the first connecting block 341 and the second connecting block 342, maintain the support of the roller 32 on the separation conveyor belt 33, prevent the surface of the separation conveyor belt 33 from collapsing, and ensure the normal transmission of the separation conveyor belt 33.

[0034] The movable assembly 35 includes a rotating block 351 arranged on the fixed frame 31, a connecting shaft 352 arranged on the rotating block 351, a first motor 353 arranged on the connecting shaft 352, and a movable rod 354 arranged on the rotating block 351. The rotating block 351 is used to rotate to push and pull the movable rod 354, thereby driving the two groups of movable support assemblies 34 to move closer or farther away, thereby cooperating with the movable support assembly 34 to change the length and width of the rectangle formed by the separation conveyor belt 33. The connecting shaft 352 is used to control the rotation of the rotating block 351 and at the same time support the rotating block 351. The first motor 353 is used to generate power to drive the connecting shaft 352 to rotate, thereby driving the rotating block 351 to rotate. The movable rod 354 is used to push and pull the movable support assembly 34 with the rotation of the rotating block 351, so as to change the length and width of the rectangle formed by the separation conveyor belt 33, thereby controlling the separation conveyor belt 33 to move closer to or away from the detection conveyor belt 1. The fixing frame 31 is provided with a first supporting hole 313 matching the connecting shaft 352, and is used to match the connecting shaft 352 to play a supporting role; The first connection block 341 is provided with a rotation groove 3411 for cooperating with the movable rod 354 , so as to cooperate with the rotation of the movable rod 354 .

[0035] The rest of the structure is the same as that of Example 1.

[0036] In summary, when the placement box 2 should detect that the conveyor belt 1 is transported to the bottom of the separation conveyor belt 33, the first motor 353 is started to drive the connecting shaft 352 to rotate. At this time, the rotating block 351 rotates synchronously. At this time, the rotating block 351 pulls the movable rod 354 to the middle. At this time, the movable rod 354 pulls the first connecting block 341 to the middle through the rotating groove 3411. At this time, the upper support blocks 321 approach each other through the support groove 311, and the lower support blocks 321 approach each other through the movable groove 312 while moving downward. At this time, the support spring 345 is slowly released with the movement of the first connecting block 341, maintaining the tension of the first connecting block 341 and the second connecting block 342 on the roller 32, thereby keeping the separation conveyor belt 33 from collapsing. At this time, the width of the rectangle formed by the separation conveyor belt 33 increases and the length decreases. The bottom of the conveyor belt 33, that is, the wide side of the rectangle formed by the separation conveyor belt 33 is close to the placement box 2. At this time, the magnet 331 adsorbs the metallized capacitor a on the placement box 2 through the pins of the metallized capacitor a. At this time, the first motor 353 is controlled to reverse, and the first connecting block 341 is pushed by the movable rod 354 to drive the movable support assembly 34 to restore its original state as a whole. At this time, the width of the rectangle formed by the separation conveyor belt 33 is reduced and the length is increased. At this time, the bottom of the separation conveyor belt 33 drives the metallized capacitor a to leave the placement box 2. At this time, the metallized capacitor a is suspended on the separation conveyor belt 33 by the attraction of the magnet 331 to the pins. At this time, the main body of the metallized capacitor a is fully exposed to the outside world. At this time, the separation conveyor belt 33 drives the metallized capacitor a through the visual inspection unit 4. At this time, the visual inspection unit 4 can comprehensively inspect the appearance of the metallized capacitor a.

[0037] Example 3, reference Figure 1-Figure 9 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: the metallized capacitor a is inspected for appearance, and unqualified ones are removed. Compared with embodiment 1, further, the visual inspection unit 4 includes a fixing plate 41 disposed on the fixing frame 31 for supporting and fixing, a motion camera 42 disposed on the fixing plate 41 for inspecting the appearance of the metallized capacitor a passing by, and a separation component 43 disposed on the fixing plate 41 for knocking down the unqualified capacitors detected by the motion camera 42 and separating them from qualified capacitors.

[0038] There are multiple groups of motion cameras 42 , and the motion cameras 42 are distributed in an arc shape on the fixing plate 41 , so that the appearance of the metallized capacitor a can be detected more comprehensively from multiple angles.

[0039] The separation assembly 43 includes a second motor 431 disposed on the fixed plate 41 for generating power, a rotating rod 432 disposed on the second motor 431 for rotating in coordination with the second motor 431, and a separation rod 433 disposed on the rotating rod 432 for rotating in coordination with the rotation of the rotating rod 432 to knock down the unqualified metallized capacitor a on the separation conveyor belt 33; The fixing plate 41 is provided with a second supporting hole 411 which cooperates with the rotating rod 432 and plays a supporting role in cooperation with the rotating rod 432 .

[0040] Among them, a guide plate 314 is set on one side of the fixed frame 31, and the upper part of the guide plate 314 is inclined toward one side of the separation conveyor belt 33, which is used to receive qualified metallized capacitors a on the separation conveyor belt 33 and guide the qualified metallized capacitors a into the collection conveyor belt 5. When the separation conveyor belt 33 drives the metallized capacitors a through the motion camera 42, under the action of gravity, the metallized capacitors a stick to the surface of the separation conveyor belt 33, and are transported to the upper surface of the separation conveyor belt 33 along with the separation conveyor belt 33. At this time, the metallized capacitor a lies flat on the separation conveyor belt 33. When the separation conveyor belt 33 drives the metallized capacitor a to approach the guide plate 314, the separation conveyor belt 33 drives the metallized capacitor a to move downward. Since the weight of the main body of the metallized capacitor a is greater than the pins, when the metallized capacitor a is transported to the side of the separation conveyor belt 33, under the action of gravity, the metallized capacitor a flips over. At this time, the pins of the metallized capacitor a are facing upward and the main body is facing downward. At this time, the metallized capacitor a is guided into the guide plate 314 through the first connecting block 341. Through the force generated by the transmission of the separation conveyor belt 33, the metallized capacitor a is left on the guide plate 314 and slides onto the collection conveyor belt 5 through the action of gravity.

[0041] The collecting conveyor belt 5 is disposed below the first supporting hole 313 .

[0042] The rest of the structure is the same as that of Example 2.

[0043] In summary, when the separation conveyor belt 33 drives the metallized capacitor a to pass through the motion camera 42, the motion camera 42 performs an appearance inspection on the suspended metallized capacitor a. When the motion camera 42 detects an unqualified metallized capacitor a, the second motor 431 is started to drive the second motor 431 to rotate by controlling the rotating rod 432 to knock down the unqualified metallized capacitor a. Since the detection conveyor belt 1 and the separation conveyor belt 33 are conveyed synchronously, when the motion camera 42 detects the metallized capacitor a, the placement box 2 just moves to the bottom of the motion camera 42. At this time, the metallized capacitor a knocked down by the separation rod 433 will fall on the placement box 2 and follow the placement box 2 to enter the next process. At this time, the qualified metallized capacitor a continues to be conveyed through the separation conveyor belt 33. At this time, the metallized capacitor a is conveyed to one side of the wide side of the rectangle formed by the separation conveyor belt 33. At this time, under the action of gravity, the metallized capacitor a is attached to the surface of the separation conveyor belt 33 until the metallized capacitor a is conveyed to the upper surface of the separation conveyor belt 33. At this time, the metallized capacitor a lies flat on the separation conveyor belt 33. When the separation conveyor belt 33 drives the metallized capacitor a to the side of the separation conveyor belt 33, under the action of gravity, the metallized capacitor a flips over. At this time, the pins of the metallized capacitor a are facing upward and the main body is facing downward. At this time, the metallized capacitor a is guided into the guide plate 314 through the first connecting block 341. Through the force generated by the transmission of the separation conveyor belt 33, the metallized capacitor a is left on the guide plate 314 and slides into the collection conveyor belt 5 through the action of gravity. It enters the next process with the transportation of the collection conveyor belt 5.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
