[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4This utility model provides a technical solution: a device for precise positioning of loading and unloading equipment, including a loading and unloading frame 1 and a gripping component 2 for gripping goods. A first push rod 3 is bolted to the top of the loading and unloading frame 1. The push rod portion of the first push rod 3 passes through the loading and unloading frame 1 and is bolted to a lifting seat 4. A positioning groove 5 is formed on the surface of the lifting seat 4. A positioning plate 6, adapted to the positioning groove 5, is provided in the inner cavity of the positioning groove 5. The surface of the positioning plate 6 is slidably connected to the inner cavity of the positioning groove 5. The positioning plate 6 is bolted to the inner wall of the loading and unloading frame 1. Furthermore, the surface of the positioning plate 6 is provided with scale lines, and it also includes a moving component 7 for adjusting the position of the goods. The moving component 7 is installed at the bottom of the lifting seat 4, and the bottom of the moving component 7 is provided with a mounting seat 8 for installing the gripping component 2. The first push rod 3 is connected to an external power cord, and the first push rod 3 is connected to a control switch through the power cord. The first push rod 3 is set as an electric push rod. Electric push rods are well-known existing technologies, and this utility model does not specifically protect or limit the first push rod 3. The first push rod 3 can be purchased from the market and used as an electric push rod with the same function.
[0024] When loading and unloading goods, the first push rod 3 is activated, which pushes the lifting seat 4 to move, causing the lifting seat 4 to slide on the surface of the positioning plate 6. The lifting seat 4 drives the gripping component 2 at the bottom to move. The staff adjusts the height of the lifting seat 4 according to the height of the goods. By observing the scale lines on the positioning plate 6, the height at which the loading and unloading equipment grips the goods is accurately positioned. Then, the gripping component 2 grips the goods, and the moving component 7 moves the goods to be transferred. When gripping goods of the same size again, it is only necessary to control the lifting seat 4 to quickly move to the position of the previous positioning height to grip again. The above scheme avoids the gripping position from floating and can accurately position the height of the gripped goods, avoiding damage or falling of goods during loading and unloading.
[0025] The positioning plate 6 is T-shaped and there are four sets of positioning plates 6. The four sets of positioning plates 6 are distributed on the inner side wall of the loading and unloading frame 1. By setting the positioning plates 6, the staff can observe the position of the lifting seat 4 on the positioning plate 6 at both the front and rear ends of the loading and unloading frame 1, which makes it convenient for the staff to adjust the positioning height.
[0026] A support rod 9 is fixedly connected to the top of the lifting seat 4. A through hole adapted to the support rod 9 is opened on the upper surface of the loading and unloading frame 1. The top of the support rod 9 passes through the through hole of the loading and unloading frame 1 and is fixedly connected to a fixing block. The support rod 9 can support the lifting seat 4 from all sides, preventing the angular deviation of the lifting seat 4 from causing damage to the positioning plate 6 when it moves vertically, and improving the stability of the lifting seat 4 when it moves in the loading and unloading frame 1.
[0027] The gripping assembly 2 includes a clamping frame 21 mounted on the bottom of the mounting base 8 and a stepper motor 22. The stepper motor 22 is fixedly mounted on the outer wall of the clamping frame 21 via a mounting plate. The output shaft of the stepper motor 22 is connected to a bidirectional screw 23 via a gearbox. The bidirectional screw 23 is located in the inner cavity of the clamping frame 21 and is rotatably connected to the inner wall of the clamping frame 21 via a rotating shaft. Clamping seats 24 are provided on both sides of the bidirectional screw 23, and clamping plates 25 are bolted to the surface of the clamping seats 24. When the stepper motor 22 is started, the output shaft of the stepper motor 22 drives the gearbox... The double-acting screw 23 rotates clockwise, causing the clamping seats 24 on both sides to move inward, so that the clamping plate 25 clamps and grabs the goods inward. Rotating counterclockwise will cause the clamping seats 24 to separate and release the goods. The stepper motor 22 is connected to an external power supply line, and the stepper motor 22 is connected to a switch that controls the forward and reverse rotation of the motor through the power supply line. The stepper motor 22 is a well-known existing technology, and this utility model does not impose specific protection or limitations on the stepper motor 22. The stepper motor 22 can be purchased from the market and used with motors of the same function.
[0028] A threaded tube 10 adapted to the bidirectional screw 23 is welded and fixed to the surface of the clamping seat 24. The inner cavity of the threaded tube 10 is threadedly connected to the bidirectional screw 23. Through the cooperation between the threaded tube 10 and the bidirectional screw 23, when the bidirectional screw 23 rotates, the threaded tube 10 can be driven to move on the surface of the bidirectional screw 23 through the threaded connection, thereby driving the clamping seat 24 to move.
[0029] The inner wall of the clamping frame 21 is provided with a support groove 11. A support block 12 is slidably connected to the inner cavity of the support groove 11. The surface of the support block 12 is fixedly connected to the surface of the clamping seat 24 by bolts. The surface of the clamping frame 21 is provided with scale lines. Through the cooperation of the support block 12 and the support groove 11, the two sides of the clamping seat 24 are supported, which improves the stability of the clamping seat 24 when it moves in the clamping frame 21. The scale lines allow the staff to accurately locate the gripping position of the gripping component 2 on the goods by observing the scale lines.
[0030] This embodiment also includes a rubber pad that is fixed to the inner wall of the clamping seat 24 by adhesive or bolts. The rubber pad is used to prevent the clamping plate 25 from clamping too hard and damaging the surface of the goods.
[0031] The moving component 7 includes a second push rod 71, which is fixed to the lower surface of the lifting seat 4 by bolts. The push rod part of the second push rod 71 is fixedly connected to a slide block 72 by bolts. The slide block 72 is fixedly connected to the mounting seat 8 by bolts. A slide groove is provided at the top of the slide block 72, and a slide rail 73 is slidably connected to the inner cavity of the slide groove. The slide rail 73 is fixedly connected to the lower surface of the lifting seat 4 by bolts. Activating the second push rod 71 moves the slide block 72, causing the slide block 72 to push the mounting seat 8 at the bottom to move. This allows the mounting seat 8 to move the gripped goods through the clamping frame 21, thus transferring the goods. The second push rod 71 is connected to an external power cord, and a control switch is connected to the power cord. The second push rod 71 is an electric push rod. Electric push rods are well-known existing technology, and this utility model does not specifically protect or limit the second push rod 71. The second push rod 71 can be purchased from the market and used with electric push rods of the same function.
[0032] In practical use: During unloading, the first push rod 3 is activated to move the lifting seat 4, allowing it to be initially adjusted according to the height of the goods. Then, the staff compares the height of the lifting seat 4 with the scale lines on the positioning plate 6 to make precise adjustments. After adjusting the height, the staff records the height of the lifting seat 4 on the scale lines. Then, the stepper motor 22 is activated. The output shaft of the stepper motor 22 drives the bidirectional screw 23 to rotate clockwise through the gearbox. This causes the bidirectional screw 23 to move the clamping seats 24 on both sides inward, so that the clamping plates 25 clamp and grab the goods inward. After grabbing, the lifting seat 4 moves upward, and the second push rod is activated. The lever 71 pushes the slide 72 to move, causing the slide 72 to move the goods above the unloading conveyor belt. The lifting seat 4 descends, and the output shaft of the stepper motor 22 drives the bidirectional screw 23 to rotate counterclockwise through the gearbox, causing the clamping plate 25 to release the goods, completing the unloading operation. After unloading, the slide 72 drives the lifting seat 4 to move above another set of goods. The lifting seat 4 is adjusted to the height of the scale line recorded by the staff, and the gripping operation can be performed again. The above scheme avoids the gripping position from floating and can accurately position the height of the gripped goods, avoiding damage or falling of goods during loading and unloading.
