[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] The utility model provides: an automatic board feeding mechanism for a high-speed placement machine, such as Figure 1-5As shown, it includes a supporting side plate 1 and a mounting plate 7, and two groups of supporting side plates 1 and mounting plates 7 are provided. A material storage rack 4 is commonly connected above the two groups of supporting side plates 1, and a feeding plate assembly 3 for automatic material pushing is provided on the corresponding surfaces of the two groups of supporting side plates 1;

[0026] The two sets of supporting side plates 1 are provided with blanking plates 6 on their sides, and the corresponding surfaces of the two sets of supporting side plates 1 and the side surfaces of the storage rack 4 are provided with moving components for driving the plates to move above the blanking plates 6;

[0027] The plate feeding assembly 3 includes a moving block 18, a pushing block 19 and a swinging module. The pushing block 19 is fixedly installed on the upper surface of the moving block 18, and the pushing block 19 is slidably set on the lower surface of the storage rack 4. The special-shaped disk 14 is driven to rotate by the first motor 2. When the limiting column 15 contacts the plane side of the special-shaped disk 14, the tension spring 20 pulls the moving block 18 to move toward the direction close to the blanking plate 6, so that it moves into the pushing groove 22 through the pushing block 19, and pushes the plate inside the storage rack 4 out of the storage rack 4, and then moves to the inside of the placement machine through the moving assembly and the blanking plate 6, thereby improving the efficiency of the placement machine in feeding the plate.

[0028] Preferably, the swing module includes a first motor 2, a special-shaped disk 14, a limit column 15, a mounting block 16 and a connecting plate 17. The first motor 2 is fixedly mounted on the side of the supporting side plate 1. The output end of the first motor 2 is keyed to a rotating shaft. The special-shaped disk 14 is fixedly sleeved on the outer arc surface of the rotating shaft. One end of the connecting plate 17 is rotatably arranged on the side of the mounting block 16. The other end of the connecting plate 17 is fixedly connected to the lower surface of the moving block 18. The mounting block 16 is fixedly mounted on the bottom plate. The connecting plate 17 rotates with the side of the mounting block 16 as the center, thereby driving the moving block 18 to rotate.

[0029] Furthermore, the limit column 15 is rotatably arranged on the side of the connecting plate 17 away from the mounting block 16, and the limit column 15 contacts the outer arc surface of the special-shaped disk 14, and one side of the special-shaped disk 14 is set as a plane. The first motor 2 is started to drive the special-shaped disk 14 to rotate. When the arc surface of the special-shaped disk 14 contacts the limit column 15, the limit column 15 will be squeezed to move in the direction away from the blanking plate 6, thereby driving the connecting plate 17, the moving block 18 and the pushing block 19 to move in the direction away from the blanking plate 6.

[0030] Furthermore, the swing module also includes a tension spring 20 and a connecting block 21. The connecting block 21 is fixedly installed on the lower surface of the storage rack 4. One end of the tension spring 20 is fixedly installed on the side of the moving block 18, and the other end of the tension spring 20 is fixedly connected to the connecting block 21. When the plane of the special-shaped disk 14 contacts the limiting column 15, the tension spring 20 pulls the moving block 18 to move toward the lower material plate 6, and at the same time drives the connecting plate 17 and the limiting column 15 to move toward the direction close to the lower material plate 6, thereby driving the pushing block 19 to move toward the direction close to the lower material plate 6.

[0031] It is worth mentioning that the moving assembly includes a second motor 8, an upper transmission roller 9, a lower transmission roller 10, a first belt pulley 11, a belt 12 and a second belt pulley 13. The second motor 8 is fixedly mounted on the side of the mounting plate 7. The upper transmission roller 9 and the lower transmission roller 10 are both rotatably arranged on the corresponding surfaces of the two sets of mounting plates 7, and the upper transmission roller 9 is connected to the output end of the second motor 8. The first belt pulley 11 is rotatably arranged at one end of the lower transmission roller 10. The upper transmission roller 9 rotates counterclockwise, and the lower transmission roller 10 rotates clockwise. The gap between the upper transmission roller 9 and the lower transmission roller 10 is consistent with the height of the plate, and the upper transmission roller 9 and the lower transmission roller 10 are both located on the side of the storage rack 4. When the plate inside the storage rack 4 is pushed out by the push block 19, the plate is driven by the rotation of the upper transmission roller 9 and the lower transmission roller 10 to move toward the direction close to the blanking plate 6, and then enters the inside of the placement machine through the blanking plate 6, thereby improving the plate feeding efficiency.

[0032] Specifically, the second belt pulley 13 is fixedly sleeved on the outer arc surface of the rotating shaft, and the first belt pulley 11 is sleeved on the outer arc surfaces of the first belt pulley 11 and the second belt pulley 13. The first motor 2 is started to drive the second belt pulley 13 to rotate, and the second belt pulley 13 drives the first belt pulley 11 to rotate through the belt 12, thereby driving the lower transmission roller 10 to rotate, so that a first motor 2 is set up to drive the lower transmission roller 10 and the special-shaped disk 14 to rotate at the same time.

[0033] In addition, a push groove 22 corresponding to the push block 19 is opened on the side of the storage rack 4 away from the unloading plate 6, and a front baffle 24 is fixedly installed on the side of the storage rack 4 close to the unloading plate 6, and a discharge groove 23 is opened between the storage rack 4 and the front baffle 24. The push block 19 pushes out a group of plates at the bottom layer inside the storage rack 4 by entering the push groove 22, and the height of the discharge groove 23 is consistent with the height of a group of plates, thereby ensuring that only one group of plates comes out each time.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
