[0010] For example, see below. Figures 1 to 7As shown, an automatic feeding and stacking device for diffusion plates includes a main frame 10. A central feeding channel 11 extending forward and backward is formed in the middle of the top plate of the main frame 10. A lower mounting cavity (not shown in the attached diagram) is formed on the ground below the center of the central feeding channel 11. An electric lifting platform 200 is located in the lower mounting cavity, with its bottom surface fixed to the bottom surface of the lower mounting cavity. The top surface of the lifting plate of the electric lifting platform 200 is flush with the ground. A material picking channel 101 is formed on the lower side wall of the main frame 10 corresponding to the electric lifting platform 200. A wire displacement sensor is installed in the channel to control and sense the lifting height of its lifting plate. The electric lifting platform 200 is a known existing device and can be purchased directly from the market; therefore, it will not be described in detail here.

[0011] Meanwhile, the distance between the front and rear side walls of the material receiving channel 101 is about 150mm to 200mm greater than the distance between the front and rear side walls of the stacked diffuser plates, so that the two forks of the hydraulic pallet truck can be moved to the left and right sides of the lifting plate by manual labor to receive the stacked diffuser plates.

[0012] The top surface of the main frame 10 is fixed with horizontal guide rails 12 extending to the left and right at the front and rear. The two horizontal support plates 20 extending forward and backward are located above the left and right sides of the central material discharge channel 11. The bottom surfaces of the front and rear of the two horizontal support plates 20 are fixed with guide sliders. The horizontal guide rails 12 are inserted into the guide grooves formed in the middle of the bottom surface of the corresponding guide sliders and cooperate with the guide grooves. A servo motor 13 is fixed to the top surface of the left or right middle part of the top plate of the main frame 10. Two bearing seats are fixed to the top surface of the top plate of the main frame 10 near the output shaft of the servo motor 13. The rotating shafts of the drive synchronous pulley 14 and the transmission synchronous pulley 15 are fixed on the inner rings of the bearings in the corresponding bearing seats. The output shaft of the servo motor 13 is fixed to one end of the rotating shaft of the drive synchronous pulley 14 through a coupling. The first synchronous belt 16 is tensioned on the drive synchronous pulley 14 and the transmission synchronous pulley 15. The front and rear parts of the left and right sides of the top plate of the main frame 10 are all open. Each of the support bearing seats has a movable synchronous belt pulley 17 connected to it via bearings.

[0013] Furthermore, the top surface of the horizontal support plate 20 is formed with a plurality of mounting recesses, the universal ball 21 is located in the mounting recesses and fixed on the horizontal support plate 20, and the top of the ball of the universal ball 21 extends out of the top surface of the horizontal support plate 20.

[0014] Furthermore, a front guide plate 19 is fixed to the top surface of the top plate of the main frame 10. Multiple mounting recesses are formed on the top surface of the front guide plate 19. The universal ball 21 is located in the mounting recesses and fixed on the front guide plate 19. The top of the ball of the universal ball 21 extends out of the top surface of the front guide plate 19 and is level with the top of the ball of the universal ball 21 of the horizontal support plate 20.

[0015] Furthermore, an upper support frame 30 is fixed on the top surface of the top plate of the main frame 10. On the opposite walls of the intermediate support frames fixed on the left and right sides of the upper support frame 30, front-to-back extending limiting beams 31 are fixed. On the opposite walls of the two limiting beams 31, guide plates 32 are fixed. The bottom surface of the guide plates 32 is formed with downward extending guide protrusions 321. The middle part of the horizontal support plate 20 is formed with multiple left-to-right extending guide grooves. The guide protrusions 321 are inserted into the corresponding guide grooves and cooperate with the guide grooves.

[0016] Furthermore, vertical fixing plates are fixed to the middle of the opposite walls of the transverse beams of the intermediate support frame fixed on the left and right sides of the upper support frame 30. Electric push rods 320 (one electric push rod 320 is omitted in the figure) are fixed to the outer walls of the vertical fixing plates. The end of the push rod of the electric push rod 320 extends out of the vertical fixing plate and is fixed with a vertically downward extending side adjustment positioning plate 33. The two side adjustment positioning plates 33 are opposite each other on the left and right. The left and right side walls of the diffusion plate 100 to be stacked on the top surface of the two horizontal support plates 20 face the two side adjustment positioning plates 33.

[0017] Furthermore, a connecting support frame extending forward and backward is fixed on the bottom surface of the top frame of the upper support frame 30. A first linear motor module 40 extending forward and backward is fixed at the rear part of the bottom surface of the connecting support frame, and a second linear motor module 50 is fixed at the front part of the bottom surface of the connecting support frame. A bottom component is fixed on the moving block of the first linear motor module 40, and a double-cylinder is fixed on the front wall of the bottom component. A rear limiting plate 41 is fixed at the bottom end of the double push rod of the double-cylinder. A double-cylinder is fixed on the bottom component fixed on the moving block of the second linear motor module 50, and a front limiting plate 51 is fixed at the bottom of the double push rod of the double-cylinder. The front and rear side walls of the diffusion plate 100 to be stacked, placed on the top surface of the two horizontal support plates 20, face the front limiting plate 51 and the rear limiting plate 41.

[0018] Rollers 1 are movably connected to opposite sides of the two horizontal support plates 20 via hinge shafts. The top of the rollers 1 is higher than the top surface of the horizontal support plate 20, but lower than the top of the universal ball 21 of the horizontal support plate 20. The outer sides of the rollers 1 of the two horizontal support plates 20 extend out of the opposite walls of the two horizontal support plates 20.

[0019] All electrical components in this embodiment are electrically connected to the control host via electrical connection lines, and are controlled by the control host. This is a conventional structure and will not be described in detail here.

[0020] In this embodiment, during use, the front part of the connecting support frame extends beyond the front part of the upper support frame 30. Then, the diffuser plate 100 is conveyed by the aforementioned equipment to the top of the universal balls 21 of the two horizontal support plates 20 and the front guide plate 19. Then, the double push rods of the double-cylinder of the second linear motor module 50 push, causing the front limit plate 51 to descend. Through the movement of the moving block of the second linear motor module 50, the front limit plate 51 is pressed against the front end of the diffuser plate 100 and moved backward. At the same time, the moving block of the first linear motor module 40 moves forward to the corresponding position (according to the feed diffuser plate). The size of the diffuser plate 100 is predetermined (its moving position is set in advance), and it is pushed by the double push rods of the corresponding double-cylinder cylinder, so that the rear limit plate 41 is lowered until the rear wall surface of the diffuser plate 100 contacts the rear limit plate 41 of the moving block of the first linear motor module 40, while its front end surface rests on the rear wall surface of the front limit plate 51. Then, the push rods of the electric push rods 320 on both sides push, so that the left and right sides of the diffuser plate 100 contact the two side adjustment positioning plates 33 (the pushing distance of the push rods of the electric push rods 320 is also predetermined according to the specifications of the diffuser plate 100 being transported). At this point, the position adjustment is completed. After completion, the servo motor 13 is operated to make the two horizontal support plates 20 relatively far apart. At this time, the lifting plate of the electric lifting platform 200 is below and close to the horizontal support plate 20. As the horizontal support plate 20 moves, the diffuser plate 100 descends and falls onto the lifting plate of the electric lifting platform 200 (the top surface of the lifting plate is fixed with an elastic layer to reduce the occurrence of breakage) to receive the material (the distance between it and the top surface of the lifting plate when it falls is about 10mm, so there will be basically no excessive movement or breakage). Then, the lifting plate of the electric lifting platform 200 descends by the thickness of the diffuser plate 100. Then, all components return to their original positions and continue to receive newly delivered diffuser plates 100. This stacking and receiving method can be used to receive materials. In this embodiment, when the lifting plate of the electric lifting platform 200 is receiving material, the forks of the hydraulic pallet truck can be manually positioned on the left and right sides of the electric lifting platform 200. After receiving material such as 50 diffuser plates 100, the lifting plate of the electric lifting platform 200 can be lowered to the bottom. When it reaches the lowest point, the top surface of the lifting plate is level with the ground. At this time, the stacked diffuser plates 100 are placed on the top surface of the forks of the hydraulic pallet truck. Subsequently, the hydraulic pallet truck can be manually removed from the material retrieval channel 101 to retrieve the material, which is very convenient.
