Circuit boards need to be transported by a feeding machine during production.

[0003] The existing feeder has the following problems: The existing feeder does not allow for easy adjustment of the conveyor belt tension, which leads to problems with the inconvenience of tension adjustment after the conveyor belt is replaced. Utility Model Content

[0004] The purpose of this invention is to provide a circuit board feeder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circuit board feeder, comprising a frame, a driver mounted on the frame, a rotating wheel mounted on the frame, a conveyor belt mounted on the rotating wheel, an adjustment structure mounted on the frame, the adjustment structure comprising a rotating rod, the rotating rod disposed within the frame, a sealing box mounted on the frame, a worm gear connected within the sealing box, a worm wheel disposed inside the sealing box, a gear mounted on the rotating rod, a slide seat disposed within the frame, a toothed plate disposed on the surface of the slide seat, and a docking structure disposed within the slide seat.

[0006] Preferably, the slide is provided with a rolling element, and the frame is provided with a fixing groove.

[0007] Preferably, the slide is provided with rolling elements at both the upper and lower ends, and two rolling elements are provided at one end, which are located at the left and right ends of the slide respectively.

[0008] Preferably, the rolling element abuts against the inside of the fixed groove.

[0009] Preferably, the docking structure includes a docking rod, which is connected to the rotating wheel. A push rod is connected to the docking rod via a spring. A locking rod is provided in the docking rod, and a spring is connected to the locking rod. A groove is provided on the push rod.

[0010] Preferably, the toothed plate has a protruding plate at its end.

[0011] Compared with the prior art, the beneficial effects of this utility model are: Rotating the worm gear drives the worm wheel to rotate, which in turn drives the rotating rod to rotate, and at the same time drives the gear to rotate. Since the gear meshes with the toothed plate, the rotation of the gear will drive the toothed plate to slide, which will drive the slide block to slide, and then drive the rotating wheel to slide in parallel. This will push the conveyor belt to adjust the tension of the conveyor belt, thus achieving a convenient and effective way to adjust the tension of the conveyor belt.

[0012] When the rotating wheel is damaged and needs to be replaced, push the push rod to make the groove slide, which releases the limit on the locking rod. Under the action of the spring, the locking rod moves out of the slide, releasing the limit on the connecting rod. Then the rotating wheel can be removed for replacement and maintenance.

Detailed Implementation

[0015] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides a circuit board feeding machine, including a frame 1, a driver 2 installed at the lower end of the frame 1, a rotating wheel 3 rotatably connected to the frame 1, the rotating wheel 3 being respectively installed on the frame 1, the driver 2 and the adjustment structure 5, a conveyor belt 4 being sleeved on the rotating wheel 3, and the adjustment structure 5 being provided on the frame 1.

[0017] Specifically, the rotating wheel 3 on the driver 2 is driven to rotate, thereby driving the conveyor belt 4 to rotate. The circuit board is placed on the conveyor belt 4, and the rotating conveyor belt 4 will drive the circuit board to be transported, so as to realize the feeding of the circuit board.

[0018] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 This utility model provides a circuit board feeder. The adjusting structure 5 includes a rotating rod 51. The rotating rod 51 is rotatably connected to the frame 1. A sealing box 52 is provided on the frame 1. A worm gear 53 is rotatably connected to the sealing box 52. A worm wheel 54 is provided inside the sealing box 52. The worm wheel 54 is fixed to the rotating rod 51 and meshes with the worm gear 53. A gear 55 is provided on the rotating rod 51. A slide 56 is provided in the frame 1. A toothed plate 57 is provided on the surface of the slide 56 and meshes with the gear 55. A docking structure 58 is provided in the slide 56.

[0019] The toothed plate 57 has a protruding plate at its end, which prevents the gear 55 from disengaging from the toothed plate 57.

[0020] The slide 56 is provided with rolling elements 59, and the frame 1 is provided with a fixing groove 510. Rolling elements 59 are provided at both the upper and lower ends of the slide 56. Two rolling elements 59 are provided at one end, and they are located at the left and right ends of the slide 56 respectively. The rolling elements 59 abut against the inside of the fixing groove 510 to avoid friction between the slide 56 and the frame 1, while ensuring the flexibility and stability of the slide 56.

[0021] The docking structure 58 includes a docking rod 581, which is connected to the rotating wheel 3. A push rod 582 is connected to the docking rod 581 via a spring. A locking rod 583 is provided in the docking rod 581, and a spring 584 is connected to the locking rod 583. A groove 585 is provided on the push rod 582. The rotating wheel 3 is connected to the slide block 56 through the docking structure 58.

[0022] Specifically, rotating the worm gear 53 drives the worm wheel 54 to rotate, which in turn drives the rotating rod 51 to rotate, and simultaneously drives the gear 55 to rotate. Since the gear 55 is meshed with the toothed plate 57, the rotation of the gear 55 will drive the toothed plate 57 to slide, which will drive the slide block 56 to slide, and then drive the rotating wheel 3 to slide in parallel. This will then push the conveyor belt 4 to adjust the tension of the conveyor belt 4, thus achieving a convenient and effective adjustment of the tension of the conveyor belt 4.

[0023] When the rotating wheel 3 is damaged and needs to be replaced, push the push rod 582 to cause the groove 585 to slide, releasing the limit on the locking rod 583. Under the action of the spring 584, the locking rod 583 moves out of the slide 56, releasing the limit on the connecting rod 581. Then the rotating wheel 3 can be removed for replacement and maintenance.
