Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, specifically to an automatic feeding device for surface mount PCB circuit boards. Background Technology

[0002] Circuit boards make circuits miniaturized and more intuitive, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards are an indispensable component in modern electronic devices. All electronic devices, whether large machinery, personal computers, communication base stations or mobile phones, home appliances or electronic toys, use circuit boards. Circuit boards need to be processed multiple times during the production process. After a circuit board has gone through one processing step, it needs to be transported to the next processing step by a feeding device.

[0003] Chinese invention patent CN202222659984.7 discloses an automatic feeding device for a high-speed SMT pick-and-place machine, including a hopper, a pushing mechanism installed on one side of the hopper, and a guiding mechanism installed on the other side of the hopper. The pushing mechanism includes a mounting frame, a pushing cylinder fixedly connected to the side of the mounting frame, a pushing rod fixedly connected to the output end of the pushing cylinder, and a pushing block fixedly connected to the end of the pushing rod away from the pushing cylinder. This invention, through the cooperation of the hopper, pushing mechanism, and guiding mechanism, realizes an automatic feeding device for a high-speed SMT pick-and-place machine. It not only adopts a stacking method for feeding, effectively reducing the floor space, but also achieves precise feeding of the circuit boards to be processed through the feeding mechanism, and facilitates adjustment of the feeding height, thus adapting to processing tables of different heights and improving the practicality of the feeding device.

[0004] After the device pushes the lower circuit board, the stacked circuit boards will fall onto the push rod by gravity, affecting the retraction of the push block, causing jamming, and easily leading to machine downtime. The continuity of feeding is poor.

[0005] To address this, an automatic feeding device for surface mount PCB circuit boards is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an automatic feeding device for surface mount PCB circuit boards to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for surface mount PCB circuit boards, comprising a base, a pair of storage racks on the upper surface of the base, PCB bodies evenly distributed sliding on the inner sidewall of the storage racks, a movable plate between the lower side of the storage racks and the upper surface of the base, a pair of grooves on the inner sidewall of the movable plate, a material dropping area on the left side of the upper surface of the movable plate, a mounting plate fixedly connected to the right sidewall of the base, a cylinder mounted on the right sidewall of the mounting plate, a central rod fixedly connected to the lower side of the left sidewall of the storage racks, and a rotating plate rotatably connected to the outer sidewall of the central rod.

[0008] As a further preferred embodiment of this technical solution: an iron sheet is fixedly connected to the right side wall of the rotating plate, and a magnet is fixedly connected to the left side wall of the storage rack.

[0009] As a further preferred embodiment of this technical solution: the outer side wall of the storage rack is fixedly connected with an ear plate, and the upper surface of the base is provided with evenly distributed threaded holes, and the inner side wall of the threaded holes is threadedly connected with a threaded rod.

[0010] As a further preferred embodiment of this technical solution: the upper surface of the base is provided with a sliding groove, the inner sidewall of the sliding groove is slidably connected to a slider, the right end of the slider is fixedly connected to the output end of the cylinder, and the upper surface of the slider is fixedly connected to the lower surface of the moving plate.

[0011] As a further preferred embodiment of this technical solution: a guide plate is hinged to the left side wall of the base, and a pair of support rods are installed on the left side wall of the base.

[0012] As a further preferred embodiment of this technical solution: the lower surface of the base is fixedly connected with evenly distributed support legs.

[0013] As a further preferred embodiment of this technical solution: the thickness of the blanking area is equal to the thickness of the circuit board body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In use, the cylinder pulls the moving plate to the right, and the slider slides in the groove, improving the stability of the moving plate. When the material dropping area moves to below the circuit board body, the bottom circuit board body falls into it. The moving plate is then controlled to move the circuit board body to the left, and the rotating plate rotates clockwise under the thrust. After losing the push of the circuit board body, it resets by gravity. The iron sheet and magnet come into contact and attract each other, reducing the shaking when the rotating plate resets. At this time, the moving plate is controlled to move to the right again, and the circuit board body is blocked by the rotating plate. After losing the support of the moving plate, it falls and is caught by the guide plate and slid to the material loading area. At this time, a new circuit board body fills the material dropping area again. This process is repeated to continuously and stably load materials, making it less likely to cause jamming and reducing downtime. Attached Figure Description

A moving plate 4 is provided between the lower side of the storage racks 2 and the upper surface of the base 1. A pair of grooves 5 are formed on the inner sidewall of the moving plate 4. A material dropping area 6 is formed on the left side of the upper surface of the moving plate 4. A mounting plate 7 is fixedly connected to the right side wall of the base 1. A cylinder 8 is installed on the right side wall of the mounting plate 7. A central rod 9 is fixedly connected to the lower side of the left side wall of the storage racks 2. A rotating plate 10 is rotatably connected to the outer side wall of the central rod 9. In use, multiple circuit board bodies are fed into the storage racks. 3. The stacked circuit boards are placed inside the storage rack 2 and supported at the bottom by the moving plate 4. When feeding, the cylinder 8 is activated to pull the moving plate 4 to the right. When the dropping area 6 moves to below the circuit board body 3, the bottom circuit board body 3 falls into it. The moving plate 4 is then controlled to move the circuit board body 3 to the left. The rotating plate 10 is pushed and rotates clockwise. After losing the push of the circuit board body 3, it resets by gravity. At this time, the moving plate 4 is controlled to move to the right again. The circuit board body 3 is blocked by the rotating plate 10 and falls after losing the support of the moving plate 4. At this time, a new circuit board body 3 fills the dropping area 6 again. This process is repeated to continuously and stably feed the circuit board body, which is less likely to cause jamming and reduces downtime.

[0024] In this embodiment, specifically: an iron sheet 11 is fixedly connected to the right side wall of the rotating plate 10, and a magnet 12 is fixedly connected to the left side wall of the storage rack 2; the iron sheet 11 and the magnet 12 are attracted to each other, reducing the shaking of the rotating plate 10 when it is reset.

[0025] In this embodiment, specifically: an ear plate 13 is fixedly connected to the outer side wall of the storage rack 2, and a threaded hole 14 is evenly distributed on the upper surface of the base 1. A threaded rod 15 is threadedly connected to the inner side wall of the threaded hole 14. The threaded rod 15 is screwed into the threaded hole 14 to fix the storage rack 2 on the base 1.

[0026] In this embodiment, specifically: a groove 16 is provided on the upper surface of the base 1, and a slider 17 is slidably connected to the inner side wall of the groove 16. The right end of the slider 17 is fixedly connected to the output end of the cylinder 8, and the upper surface of the slider 17 is fixedly connected to the lower surface of the moving plate 4. The slider 17 slides in the groove 16, which improves the stability of the moving plate 4.

[0027] In this embodiment, specifically: a guide plate 18 is hinged to the left side wall of the base 1, and a pair of support rods 19 are installed on the left side wall of the base 1; the circuit board body 3 is held by the guide plate 18, and the inclined setting facilitates the sliding of the circuit board body 3 to the material loading area.

[0028] In this embodiment, specifically: the lower surface of the base 1 is fixedly connected with evenly distributed support legs 20; the support legs 20 are used to support and fix the base 1.

[0029] In this embodiment, specifically: the thickness of the material dropping area 6 is equal to the thickness of one circuit board body 3; ensuring that the material dropping area 6 can only move one circuit board body 3 at a time.

[0030] The working principle of this utility model is as follows: In use, multiple circuit board bodies 3 are stacked in the storage rack 2, and the bottom is supported by the moving plate 4. When loading, the cylinder 8 is activated to pull the moving plate 4 to the right, and the slider 17 slides in the slide groove 16, which improves the stability of the moving plate 4. When the dropping area 6 moves to the bottom of the circuit board body 3, the bottom circuit board body 3 falls into it. The moving plate 4 is controlled to drive the circuit board body 3 to move to the left. The rotating plate 10 is pushed and rotates clockwise. After losing the push of the circuit board body 3, it is reset by gravity. The iron plate 11 and the magnet 12 come into contact and attract each other, reducing the shaking when the rotating plate 10 is reset. At this time, the moving plate 4 is controlled to move to the right again. The circuit board body 3 is blocked by the rotating plate 10. After losing the support of the moving plate 4, it falls and is caught by the guide plate 18. The inclined setting makes it easy for the circuit board body 3 to slide to the loading area. At this time, the new circuit board body 3 is filled into the dropping area 6 again. This process is repeated to continuously and stably load the circuit board body 3, which is less likely to cause jamming and reduces downtime.
