[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-3 The present invention provides a technical solution: a lifting device capable of automatic unloading, comprising: a lifting structure 5, a cylinder 4, a connecting plate 2 and a support plate 1, wherein the support plate 1 is used to support and fix the support structure 11, and the support plate 1 is in a Y shape, and the support structure 11 is supported on the support plate 1, and the lifting structure 5 comprises a worm gear 52, which is used to change the lateral rotation force into the up and down movement force of the lifting rod 55, thereby being used to adjust the position of the connecting plate 2, and a power connecting rod 53 and a lifting rod 55 are provided on the worm gear 52, and a turbine is provided in the worm gear 52, which drives the thread to rotate through the power connecting rod 53, thereby driving the lifting rod 55 to move up and down, and the power connecting rod 53 rotates The lifting rod 55 is driven up and down by the worm gear 52, and the connecting plate 2 and the support plate 1 are driven to move by the lifting rod 55. The overall height of the adjustment device is convenient for use by workers of various body shapes. The cylinder 4 is used to adjust the height of the support plate 1 separately, so that the height of the connecting plate 2 exceeds the height of the support plate 1, so that the workpiece supported by the support plate 1 can be supported by the connecting plate 2 and separated from the support plate 1. When using the inclined plate 21 of the connecting plate 2, the workpiece rolls and falls to one side along the inclined plate 21, thereby completing the automatic unloading of the workpiece. The support plate 1 is used to support the workpiece and is used to process the workpiece when the support plate 1 supports it. The connecting plate 2 includes an inclined plate 21, and the inclined plate 21 automatically unloads the workpiece.

[0025] The worm gear 52 of the lifting mechanism 5 rotates via the power connecting rod 53, driving the internal turbine to rotate the threads, which in turn transforms the lateral rotational force into the up-and-down force of the lifting rod 55. This in turn drives the connecting plate 2 and the support plate 1 to move, adjusting the overall height of the device to accommodate workers of different sizes. When unloading is required, the cylinder 4 operates independently, adjusting the height of the support plate 1 so that the connecting plate 2 exceeds the height of the support plate 1. At this time, the workpiece is transferred from the support plate 1 to the connecting plate 2. Because the connecting plate 2 is equipped with an inclined plate 21, the workpiece rolls and falls to one side along the inclined plate 21, completing the automatic unloading process. While the workpiece is supported by the support plate 1, the corresponding processing operations can be performed on the workpiece.

[0026] The support plate 1 is also provided with a support structure 11 for supporting the workpiece. The support structure 11 is Y-shaped and is provided with a number of rotating beads 111. The rotating beads 111 are used to reduce friction on the workpiece. The support structure 11 is also provided with rotating beads 111. The rotating beads 111 are used to ensure that the workpiece can rotate when supporting the workpiece.

[0027] The support structure 11 is Y-shaped and arranged on the support plate 1 to support the workpiece. The several rotating balls 111 arranged thereon play a key role during operation. When the workpiece is placed on the support structure 11, the rotating balls 111 come into contact with the workpiece. Since the rotating balls 111 can roll freely, when the workpiece needs to be moved or adjusted in position, the rotating balls 111 greatly reduce the friction between the workpiece and the support structure 11. When the workpiece needs to be rotated, the external force applied to the workpiece can be used with the help of the rolling characteristics of the rotating balls 111, allowing the workpiece to rotate easily around the support structure 11, thereby achieving flexible adjustment of the workpiece position and angle, meeting the requirements of different processes for the workpiece posture.

[0028] The bottom of the support plate 1 and the connecting plate 2 are both arranged on the separation structure 3. This arrangement can ensure that the separation structure 3 can move the support plate 1 and the connecting plate 2 up and down as a whole, thereby adjusting the overall height of the device. The separation structure 3 includes a lifting plate 31 and a first fixed plate 32. The lifting plate 31 is provided with a support plate 1, and the support plate 1 can move up and down. The lifting plate 31 is provided with a limit seat 34, and the limit seat 34 is used to limit the pneumatic rod 33, and the pneumatic rod 33 is used to push the support bottom plate 12 up and down, thereby adjusting the height of the support plate 1. The pneumatic rod 33 is inserted in the limit seat 34. When the pneumatic rod 33 is pushed upward by the cylinder 4, the height of the support plate 1 can exceed the connecting plate 2. When the pneumatic rod 33 is pulled downward by the cylinder 4, the height of the support plate 1 can be lower than the connecting plate 2, allowing the connecting plate 2 to lift the workpiece on the support plate 1, allowing the workpiece to roll down along the inclined plate 21 to complete the unloading operation.

[0029] The bottoms of the support plate 1 and the connecting plate 2 are both arranged on the separation structure 3, so that the separation structure 3 can move the two up and down as a whole, thereby adjusting the overall height of the device. The separation structure 3 includes a lifting plate 31 and a first fixed plate 32. The lifting plate 31 carries the support plate 1 and can drive it to move up and down. The limit seat 34 on the lifting plate 31 limits the pneumatic rod 33. The pneumatic rod 33 is responsible for pushing the support bottom plate 12 up and down, thereby adjusting the height of the support plate 1. When the cylinder 4 pushes the pneumatic rod 33 upward, the height of the support plate 1 exceeds the connecting plate 2; when the cylinder 4 pulls the pneumatic rod 33 downward, the height of the support plate 1 is lower than the connecting plate 2. At this time, the connecting plate 2 receives the workpiece on the support plate 1, and the workpiece rolls downward with the help of the inclined plate 21 of the connecting plate 2, thereby completing the unloading operation.

[0030] A cylinder 4 is provided at the bottom of the separation structure 3, and a valve 42 is provided on the cylinder 4. The cylinder 4 is used to intake air into the cylinder 4, so that the cylinder 4 can push the pneumatic rod 33 to move upward. The cylinder 4 is provided on a mounting seat 41, and the mounting seat 41 is used to fix the cylinder 4 in the first fixed plate 32. The mounting seat 41 is provided at the bottom of the first fixed plate 32.

[0031] The lifting structure 5 also includes a lifting port 51 provided at the top of the worm gear 52. The lifting port 51 is used to limit the power connecting rod 53 to ensure that the power connecting rod 53 can move in a straight line. The worm gear 52 is used to limit the lifting rod 55. A bearing seat 54 is provided at the bottom of the worm gear 52. The bearing seat 54 is used to stabilize the worm gear 52. The worm gear 52 is used to transfer the rotational force of the power connecting rod 53 so that the lifting rod 55 can move up and down.

[0032] In the lifting structure 5, the rotational force of the power connecting rod 53 is the starting power source for the entire lifting action. When the power connecting rod 53 is running, the worm gear 52 plays a key role. It converts the rotational force of the power connecting rod 53, and then drives the lifting rod 55 to move up and down. In this process, the lifting port 51 provided at the top of the worm gear 52 limits the power connecting rod 53, ensuring that the power connecting rod 53 always moves in a straight line, and provides stable power input for the worm gear 52. At the same time, the internal structure of the worm gear 52 limits the lifting rod 55, ensuring that the lifting rod 55 can only move along the predetermined up and down direction to achieve precise lifting action. The supporting seat 54 at the bottom of the worm gear 52 provides stable support for the entire worm gear 52, ensuring that it will not be displaced or shaken due to factors such as uneven force during operation, ensuring that the entire lifting structure 5 operates stably and reliably, and realizing efficient lifting function.

[0033] The bottom of the supporting seat 54 is provided with a connecting structure 6, including a second fixing plate 62 for connecting the lifting structure 5, and the second fixing plate 62 is used to support the first fixing plate 32 and the second fixing plate 62, thereby stabilizing the overall connection of the device and ensuring that it will not tilt when in use. A connecting seat 64 is provided on the sliding rod 61, and the connecting seat 64 is used to connect the support rod 63. The support rod 63 is fixed on the connecting seat 64, and the support rod 63 is used to connect the first fixing plate 32 and the second fixing plate 62. A separation structure 3 is provided on the top of the support rod 63, and a limiting sleeve 611 is provided at the bottom of the first fixing plate 32. The limiting sleeve 611 is used to limit the sliding rod 61, and the limiting sleeve 611 is sleeved with the sliding rod 61, and the sliding rod 61 can be adjusted along with the lifting and lowering of the worm gear 52. The sliding rod 61 is provided on the sliding opening 65 of the second fixing plate 62, and the sliding opening 65 is used to clamp the sliding rod 61, and the sliding opening 65 is used to allow the sliding rod 61 to pass through the second fixing plate 62.

[0034] The lifting structure 5 is used to support the lifting plate 31 and adjust the height of the lifting plate 31 .

[0035] When the lifting device capable of automatically unloading is in use, the connecting structure 6 at the bottom of the support seat 54 plays a key role in connecting and stabilizing the device. The second fixed plate 62 is responsible for connecting the lifting structure 5 and supporting the first fixed plate 32 and itself, thereby stabilizing the overall connection of the device and preventing tilting during use. The connecting seat 64 on the sliding rod 61 securely connects the support rod 63, which in turn connects the first fixed plate 32 to the second fixed plate 62. A separation structure 3 is also provided on the top. The limiting sleeve 611 at the bottom of the first fixed plate 32 is sleeved onto the sliding rod 61, limiting its position and ensuring that the sliding rod 61 can only move in a specific direction. When the worm gear 52 is raised or lowered, it drives the sliding rod 61 to adjust its position accordingly. The sliding opening 65 on the second fixed plate 62 clamps the sliding rod 61, allowing it to pass through the second fixed plate 62 while limiting its range of motion to a certain extent. This allows the entire connecting structure 6 to flexibly adapt to the lifting and lowering movement of the worm gear 52 while ensuring the stable connection of the various parts of the device, maintaining the stable operation of the device.
