[0012] The bottom lifting device includes a vertical threaded sleeve 32 that is movably connected to the bottom surface of the mounting cavity 30 via a bearing. A transmission gear 33 is fixed on the lower outer wall of the vertical threaded sleeve 32. A vertical lifting screw 34 is screwed into the vertical threaded sleeve 32.

A motor mounting bracket 35 is fixed on the bottom surface of the mounting cavity 30, and a lifting motor 36 is fixed on the top surface of the top plate of the motor mounting bracket 35. A drive gear 361 is fixed on the output shaft of the lifting motor 36, and the drive gear 361 meshes with the transmission gear 33.

The limit rod 313 is sensed by the upper third proximity switch 38 through its sensing end, indicating that it has been raised to the highest position and cannot be raised further. Similarly, the limit rod 313 is sensed by the lower third proximity switch 38, indicating that the lifting block 31 has been lowered to the bottom and cannot be lowered further.

[0013] Furthermore, the two support legs 11 at the front of the main frame 10 are fixed with the same front vertical baffle 19, and the rear wall of the front vertical baffle 19 faces the front end of the flat product 100.

[0014] Furthermore, upper vertical frames 50 are fixed to the outer front parts of the left crossbeam 13 and the right crossbeam 14. Upper horizontal beams 51 are fixed to the two upper vertical frames 50. Guide sliders 52 and adjusting cylinders 53 are fixed to the middle rear of the upper horizontal beams 51. The top of the push rod of the adjusting cylinder 53 is fixed to a first lifting block 54. A vertical lifting rod 55 is fixed to the bottom surface of the first lifting block 54. A vertical guide rail 56 is fixed from the middle to the bottom of the front side wall of the vertical lifting rod 55. The vertical guide rail 56 is inserted into the vertical guide groove formed in the middle of the rear wall of the guide slider 52 and cooperates with the vertical guide groove. A laser range sensor 57 is fixed to the bottom of the vertical guide rail 56. The laser of the laser range sensor 57 illuminates the topmost flat plate product 100.

[0015] Furthermore, a horizontal limiting plate 551 is fixed on the front side wall of the middle part of the vertical lifting rod 55. A first proximity switch 552 and a first limiting anti-collision component 553 are fixed on the horizontal limiting plate 551. The sensing end of the first proximity switch 552 and the anti-collision rubber block of the first limiting anti-collision component 553 face the top surface of the upper transverse beam 51.

[0016] When the first proximity switch 552 and the first limit anti-collision member 553 descend, the anti-collision rubber block of the first limit anti-collision member 553 first presses against the top surface of the upper transverse beam 51, while the sensing end of the first proximity switch 552 does not press against the top surface of the upper transverse beam 51, but it can sense the top surface of the upper transverse beam 51, indicating that it has moved into place.

[0017] Furthermore, a trolley limit frame 60 is fixed on the ground in front of the main frame 10. Two clamping cylinders 61 are fixed on the front wall of the transverse connecting plate of the trolley limit frame 60. The clamping blocks 62 of the two clamping cylinders 61 extend out of the front wall of the trolley limit frame 60 and correspond to the material receiving and lifting trolley 200.

[0018] Furthermore, two corresponding side extension plates are fixed on the ground at the left and right sides of the front of the trolley limiting frame 60. A middle limiting groove for limiting the wheels is formed between the two corresponding side extension plates. The front ends of the two corresponding side extension plates are formed with obliquely outwardly extending oblique guide portions 66.

[0019] Furthermore, connecting frames are fixed on the outer side walls of the left and right sides of the trolley limiting frame 60, and a second proximity switch 63 is fixed on each connecting frame. The second proximity switch 63 corresponds to the rear end of the receiving and lifting trolley 200, and the plane of the sensing end of the second proximity switch 63 is behind the front wall of the trolley limiting frame 60.

[0020] All electrical components in this embodiment are electrically connected to the control host via electrical connection lines. The control host is electrically connected to a control panel, which can be manually operated to perform corresponding operations, or it can be automatically controlled by the control host. These are all existing conventional structures and will not be described in detail here.

[0021] In this embodiment, the flat products 100 stacked one on top of the other are first placed on the top surface of the feeding rack 40.

[0022] When it is necessary to move the material receiving and lifting trolley 200, it is moved to the front of the main frame 10. The material receiving and lifting trolley 200 is a manual hydraulic platform truck that can be directly purchased on the market. It is existing technology and will not be described in detail here. At the same time, the material receiving and lifting trolley 200 in the attached figure is just a simple illustration and is not shown in detail.

[0023] In this embodiment, all cylinders are connected to the corresponding solenoid control valves of the pneumatic system via connecting pipes. The pneumatic system is a known existing structure and will not be described in detail here. It is controlled by a control host.

[0024] In this embodiment, the clamping cylinder 61 is a lever cylinder. When the receiving and lifting trolley 200 has not moved over, its push rod is in a retracted state, causing the clamping block 62 to tilt forward at an angle. The two rear wheels of the receiving and lifting trolley 200 move backward along the middle limiting groove until the rear wall of the crossbeam at the rear of the receiving and lifting trolley 200 presses against the front wall of the trolley limiting frame 60. The sensing end of the second proximity switch 63 senses the rear end of the receiving and lifting trolley 200, indicating that it has moved into place. At this time, the top of the clamping block 62 is lower than the bottom surface of the left and right extending crossbeam at the rear of the receiving and lifting trolley 200. Therefore, it can be pushed into place normally. Then, by pushing the push rod of the clamping cylinder 61, the clamping block 62 is flipped backward, and its top is raised above the bottom surface of the crossbeam and is in front of the crossbeam, thus limiting its movement. Then, manually operate the material receiving and lifting trolley 200 to raise its top plate to be level with the top surface of the front vertical baffle 19. By adjusting the push rod of cylinder 53 to retract, the laser rangefinder 57 descends to the bottom. The laser of the laser rangefinder 57 illuminates the topmost flat product 100 to detect its specific distance. The lifting motor 36 then operates, causing the first lifting block 54 to rise, thus lifting all the flat products 100. The height can be set according to the amount of material being picked up; for example, it can pick up 10 flat products 100 at a time. The top 10 flat products 100 are positioned above the top surface of the front vertical baffle 19. The laser range sensor 57 detects the distance they extend by irradiating the surface. When the distance reaches the specified value, it indicates that the product has moved into position. Then, the push rod of the cylinder 53 is adjusted to push the laser range sensor 57 back to its original position. Then, the servo motor 18 is activated, causing the front push plate 22 to press against the rear wall of the 10 flat products 100 and push them forward to the top plate of the receiving and lifting trolley 200. This process requires manual assistance to ensure the material handling effect. When the material receiving and lifting trolley 200 needs to pick up 20 pieces, it can be manually operated to lower the top plate a certain distance so that the topmost flat product 100 is level with the top surface of the front vertical baffle 19. Then, the material is picked up again in the same way as before. At this time, manual assistance is required to place the flat product 100 to prevent it from shifting. After the material is picked up, the push rod of the clamping cylinder 61 retracts, lowering the height of the clamping block 62. The material receiving trolley 200 can then be manually moved out to pick up the material and push it to the subsequent processing area for further processing, which is very convenient.
