DETAILED DESCRIPTION

[0020] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1-Figure 2 The utility model provides a technical solution: a feeding structure, including: an edge grinding machine 1 and a feeding machine housing 2, the feeding machine housing 2 is fixedly installed on one side of the edge grinding machine 1, and the feeding machine will send the circuit board into the edge grinding machine 1 after feeding, and a symmetrical first slide 3 is provided on the upper surface of the feeding machine housing 2, and a sliding frame 17 is slidably connected in the first slide 3, and a side wall of the first slide 3 is provided with a plurality of through holes, screws pass through the through holes and the sliding frame 17 and are threadedly connected to the two, and a driving mechanism 6 is arranged on the sliding frame 17, and the driving mechanism 6 is used to provide power for feeding the circuit board.

[0023] A discharge box 11 is fixedly installed inside the feeder housing 2, and a discharge plate 9 is arranged in the discharge box 11. A first lifting column 14 is fixedly installed on the lower surface of the discharge plate 9, and each first lifting column 14 is sleeved with a first spring 15. The discharge plate 9 is used to place PCB plates. Under the action of the first spring 15, the plates placed on the discharge plate 9 need downward pressure, otherwise they will be bounced up. At this time, the limit block 30 plays a particularly important role. The limit block 30 will contact the highest plate in the discharge box 11, and the first lifting column 14 extends into the bottom of the discharge box 11 and is slidably connected to it. The inner side wall of the discharge box 11 is provided with symmetrical limit grooves 8. The limit grooves 8 are for limiting the PCB board that is subjected to the elastic force upward, preventing the PCB board from popping out, and also preventing it from bringing out two boards that need to be polished at one time. A limit component 7 is arranged in each limit groove 8.

[0024] When in use, due to the existence of the limit block 30 and the pressure of the first spring 15, the highest point of one or more PCB boards will be the lower surface of the limit block 30. The limit component 7 limits the highest point of the PCB board after unloading. The sliding frame 17 can slide in the first slideway 3. When unloading, the unloading plate 9 will continue to move downward until it cannot move. When the driving mechanism 6 is started, the uppermost PCB board will be transported to the feed port under the action of friction.

[0025] Embodiment 2

[0026] See also Figure 3 On the basis of the first embodiment, the driving mechanism 6 includes an electric push rod 16 and a motor 23. The electric push rod 16 is fixedly mounted on the upper surface of the sliding frame 17. The output end of the electric push rod 16 is fixedly connected to the lifting box 19. The electric push rod 16 can drive the lifting of the lifting box 19. Both sides of the lifting box 19 are provided with symmetrical second slideways 22. Each second slideway 22 is slidably connected with a slider 24. The upper surface of each slider 24 is fixedly mounted with a second lifting column 20. The second lifting column 20 is sleeved with a second spring 21. The top of the second lifting column 20 passes through the top wall of the second slideway 22 and the top wall of the sliding frame 17 and is slidably connected with the two. The second lifting column 2 0 not only provides a track for the spring, but also provides a stable track for the lifting box 19. A motor 23 is fixedly installed on one side of a slider 24. The output end of the motor 23 penetrates the slider 24 and is fixedly connected to a plurality of rollers 27 through a rotating shaft. The rotation of the motor 23 drives the rotation of the rollers 27. The bottom wall of the lifting box 19 is provided with a plurality of rectangular holes 25. The plurality of rollers 27 penetrate the plurality of rectangular holes 25 and extend into the lower surface of the lifting box 19. The plurality of rollers 27 are sleeved with rubber rings 26. The rubber rings 26 increase the friction to ensure that when a slight pressure is provided between the rollers 27 and the PCB board, the rollers 27 can drive the PCB board to move and enter the feed port.

[0027] When the driving mechanism 6 is started, the electric push rod 16 is started first, and the electric push rod 16 will drive the lifting box 19 to rise and fall. When the roller 27 in the lifting box 19 contacts the PCB board and continues to descend, the spring is compressed and the roller 27 shrinks toward the inside of the lifting box 19. However, the pressure between the roller 27 and the PCB board will increase, and the motor 23 will also move upward with the roller 27. The rotation of the motor 23 will drive the rotation of the roller 27, and the rotation of the roller 27 will cause the PCB board to separate from the discharge box 11.

[0028] Embodiment 3

[0029] See also Figure 4On the basis of the second embodiment, the limiting assembly 7 includes a threaded column 28 and a limiting block 30, the limiting block 30 is slidably connected with the limiting groove 8, and the limiting block 30 slides in the limiting groove 8. The lower the limiting block 30 is, the lower the highest point of the PCB board in the material discharge box 11 is limited. The difference between the highest point of the PCB and the upper surface of the baffle 10 on the rear side of the material discharge box 11 is slightly greater than the thickness of a PCB board, which is the best. At this time, it can be ensured that the PCB board can be brought to the feeding port by the driving mechanism 6 and that only one PCB board is driven each time. B board, a third spring 31 is fixedly installed between the lower surface of the limit block 30 and the lower surface of the limit groove 8, the threaded column 28 passes through the top wall of the limit groove 8, and the lower surface of the threaded column 28 is rotatably connected with the limit block 29. The limit block 30 often contacts the limit block 30 in the limit groove 8. The limit block 30 controls the height of the limit block 30 when the threaded column 28 rotates. Therefore, the height of the limit block 30 can be controlled by rotating the threaded column 28, and the appropriate height can be selected corresponding to PCB boards of different thicknesses.

[0030] A second slide groove 13 is provided at one end of the discharge box 11, and a baffle 10 is slidably connected in the second slide groove 13. The baffle 10 can be removed. In order to facilitate loading, a first slide groove 12 is provided in the middle of the inner side of the discharge box 11, and the first slide groove 12 and the second slide groove 13 are cross-intersected. When loading, the discharge plate 9 is always at the top of the discharge box 11 under the action of the first spring 15. At this time, the discharge plate 9 must be pressed down for each added sheet. At this time, the discharge plate 9 can be pressed down and the baffle 10 can be inserted into the first slide groove 12, and the PCB board can be directly placed on the baffle 10, and the discharge plate 9 can be directly pulled out after placement.

[0031] When the PCB board is placed in actual use, the baffle plate 10 needs to be removed, and the discharge plate 9 is pressed to insert the baffle plate 10 into the first slide groove 12. After the discharge is completed, the discharge plate 9 in the first slide groove 12 can be removed to complete the discharge of the PCB board. Then, the threaded column 28 is rotated according to the thickness of the PCB board so that the difference between the highest point of the PCB and the upper surface of the baffle plate 10 on the rear side of the discharge box 11 is slightly greater than the thickness of a PCB board, which is optimal. At this time, the driving mechanism 6 is started, and the electric push rod 16 will drive the lifting box 19 to rise and fall. When the roller 27 in the lifting box 19 contacts the PCB board and continues to descend, the second spring 21 will be compressed at this time, and the roller 27 will shrink toward the inside of the lifting box 19, but the pressure between the roller 27 and the PCB board will increase, and the motor 23 will also move upward with the roller 27. The rotation of the motor 23 will drive the rotation of the roller 27, and the rotation of the roller 27 will cause the PCB board to leave the discharge box 11 and enter the feed port.
