DETAILED DESCRIPTION

[0023] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0024] See also Figure 1 The utility model provides an automatic grinding machine, including a grinding machine body 1, a transmission inlet 2, a transmission outlet 3 and an automatic feeding device 4. The grinding machine body 1 is provided with a transmission inlet 2 at the rear, the grinding machine body 1 is provided with a transmission outlet 3 at the front, and the grinding machine body 1 is provided with an automatic feeding device 4 at the rear, and the automatic feeding device 4 is docked with the transmission inlet 2.

[0025] See also Figure 2-5 The utility model provides an automatic grinding machine. The automatic feeding device 4 includes a feeding rack 41, a feeding motor 42, a conveyor belt 43, a storage frame 44, a discharge port 45, an adjustment plate 46 and an adjustment screw 47. The feeding rack 41 is arranged at the rear of the grinding machine body 1, and the feeding rack 41 is connected with the transmission entrance 2. The right side wall of the feeding rack 41 is installed with a feeding motor 42, and the inner side of the feeding rack 41 is installed with a conveyor belt 43, and the conveyor belt 43 is driven to rotate by the feeding motor 42. A storage frame 44 is arranged inside the feeding rack 41. The storage frame 44 is used to store PCB substrates. The storage frame 44 is bolted to the inner side walls of the feeding rack 41. The storage frame 44 is located directly above the conveyor belt 43. A discharge port 45 is provided at the bottom of the front side of the frame 44, and an adjusting plate 46 is provided inside the discharge port 45. The two sides of the top surface of the adjusting plate 46 are longitudinally slidably connected to the discharge port 45 through sliding rods, and an adjusting screw 47 is rotatably connected to the middle of the top surface of the adjusting plate 46, wherein the adjusting screw 47 longitudinally passes through the screw hole at the top of the discharge port 45 and is threadedly connected thereto. The adjustment plate 46 is controlled to rise and fall in the discharge port 45 by rotating the adjusting screw 47. When the adjusting plate 46 is raised, the internal height of the discharge port 45 increases, and when the adjusting plate 46 is lowered, the internal height of the discharge port 45 decreases. The internal height of the discharge port 45 can be adjusted according to the thickness of the substrate to ensure that only one substrate in the storage frame 44 can be discharged at a time.

[0026] It is further explained that the lifting height range of the adjustment plate 46 is not less than 2 cm, so that the automatic feeding device 4 has sufficient adjustment margin and can be better adapted to substrates of different thickness specifications.

[0027] Further explanation, the edges on both sides of the conveyor belt 43 are symmetrically provided with side guards 431, the height of the side guards 431 is not less than 5 mm, and the side guards 431 have a limiting function to prevent the substrate transported on the surface of the conveyor belt 43 from deviating from its original position, ensuring that the conveyor belt 43 can accurately deliver the substrate to the conveying entrance 2.

[0028] See also Figure 6-7 The utility model provides an automatic grinding machine, the automatic feeding device 4 also includes a discharge port 48, a movable door plate 49 and a positioning and stopping hinge seat 410, a discharge port 48 is opened on the top of the rear side wall of the material storage frame 44, a movable door plate 49 is arranged inside the discharge port 48, a positioning and stopping hinge seat 410 is installed at the bottom of the movable door plate 49, the positioning and stopping hinge seat 410 is fixed to the bottom surface of the discharge port 48, and the movable door plate 49 is hinged and rotated with the discharge port 48 through the positioning and stopping hinge seat 410.

[0029] It is further explained that the rotation angle range of the positioning stop hinge seat 410 is 90 degrees, and the positioning stop hinge seat 410 can be fixed and stopped at the maximum angle position, which can prevent the movable door panel 49 from flipping over and colliding with the conveyor belt 43. At the same time, the positioning stop hinge seat 410 can help the movable door panel 49 to be fixed in the open and closed states, which is easy to operate.

[0030] To further illustrate, the height difference between the discharge port 48 and the conveyor belt 43 does not exceed 5 cm. Placing the substrate from the discharge port 48 onto the conveyor belt 43 inside the storage frame 44 can ensure that the substrate is placed more stably and is not prone to strong collision with the conveyor belt 43 during placement.

[0031] Here’s how it works:

[0032] First, connect the loading motor 42 to the external power supply to ensure that it is powered normally, and then store the substrate to be processed into the storage frame 44. The specific operation process is: flip the movable door panel 49 outward to the maximum angle to open the discharge port 48, and then put the substrate from the discharge port 48 onto the conveyor belt 43 inside the storage frame 44. Because the height difference between the discharge port 48 and the conveyor belt 43 is smaller, the substrate can be placed more stably, and it is not easy to collide with the conveyor belt 43 during the placement process. After the substrates are stacked and placed on the inside of the storage frame 44, flip up the movable door panel 49 to close the inside of the discharge port 48. The positioning stop hinge seat 410 will fix the movable door panel 49 in a closed state. No additional reinforcement operation is required, and it is easy to use.

[0033] Second, the adjusting plate 46 is controlled to rise and fall in the discharge port 45 by rotating the adjusting screw 47. When the adjusting plate 46 rises, the internal height of the discharge port 45 increases. When the adjusting plate 46 is lowered, the internal height of the discharge port 45 decreases. The internal height of the discharge port 45 can be adjusted according to the thickness of the substrate to ensure that only one substrate in the storage frame 44 can be discharged at a time.

[0034] Third, an automatic loading device 4 is provided by docking with the conveying entrance 2. When in use, the loading motor 42 is started, and the loading motor 42 drives the conveyor belt 43 to run at a constant speed. During this process, the substrate at the lowest layer in the storage frame 44 will be pushed into the discharge port 45 by the conveyor belt 43 and taken out to the outside. Then the conveyor belt 43 will guide the substrate along the loading rack 41 to the conveying entrance 2. The conveying entrance 2 sends the substrate into the inside of the grinder body 1 and discharges it from the conveying outlet 3 after grinding, thereby realizing automatic loading. Compared with the original manual feeding method, it is more efficient and reduces the burden of manual labor.

[0035] The above are only preferred examples of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
