Description

Technical Field

[0001] This utility model belongs to the field of pallets, and specifically relates to an automatic pallet loading and unloading platform. Background Technology

[0002] In general, during equipment manufacturing and processing, loading and unloading devices are required for loading and unloading. Some smaller materials (products) are usually placed on pallets for loading and unloading. Pallets are sometimes called material trays. When loading and unloading, pallets are usually located on movable platforms such as conveyor belts and production lines. There are also fixed platforms or semi-fixed platforms. Semi-fixed platforms are usually fixed at the work station when working, but can be moved freely when not working. Existing semi-fixed platforms usually require manual placement of each support component when fixed, which is cumbersome. Utility Model Content

[0003] (1) Technical problems to be solved This utility model provides an automatic pallet loading and unloading platform, which aims to solve the problem of cumbersome operation that requires manual placement of each support component.

[0004] (2) Technical solution This utility model provides an automatic pallet loading and unloading platform, including a robot arm and a lifting platform. The robot arm is used to place or remove pallets on the lifting platform. The lifting platform includes a main frame, a receiving part, and a fixing part. The main frame is provided with pulleys at the bottom and a movable opening at the top. A bidirectional drive mechanism is provided inside the main frame. One output end of the bidirectional drive mechanism is used to drive the receiving part to move up and down within the movable opening, and the other output end is used to drive the fixing part to slide through the bottom of the main frame, so that the fixing part abuts against or moves away from the workshop floor.

[0005] Preferably, the bidirectional drive mechanism includes a drive component and a main shaft. The drive component is used to drive the main shaft to move. The main shaft is rotatably connected to two lifting rods, one of which is rotatably connected to the bottom of the receiving part, and the other lifting rod is rotatably connected to the top of the fixing part.

[0006] Preferably, at least two sets of bidirectional drive mechanisms are provided, and the bidirectional drive mechanisms are symmetrically distributed among each other.

[0007] Preferably, a gear is rotatably connected to the main shaft, the gear meshes with a guide tooth plate, and the guide tooth plate is fixedly installed in the main frame body.

[0008] Preferably, the main frame body is provided with a first lifting frame and a second lifting frame, the first lifting frame and the second lifting frame are rotatably connected to each of the lifting rods, the first lifting frame is used to support the receiving part, and the second lifting frame is used to install the fixing part.

[0009] Preferably, the first lifting frame and the second lifting frame have sliding parts, and the main frame body is provided with a guide ring that slides with the sliding parts.

[0010] Preferably, the main frame body is provided with a guide rod, the upper and lower ends of which pass through the first lifting frame and the second lifting frame respectively, and slide in a guiding manner with the first lifting frame and the second lifting frame.

[0011] Preferably, the fixing part includes a plurality of support legs.

[0012] Preferably, a movable position is formed within the movable opening, and limiting portions are provided at both the upper and lower ends of the movable position.

[0013] Preferably, a control module is provided on the side of the main frame for controlling the bidirectional drive mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The lifting platform is moved using pulleys. In use, the platform is pushed to the workstation, and a bidirectional drive mechanism simultaneously moves the receiving and fixing parts towards the upper and lower ends of the main frame. The receiving part is then exposed outside the opening, while the fixing part contacts the workshop floor, thus securing the lifting platform within the workstation. A robotic arm places or removes a pallet from the top of the receiving part. During movement, the bidirectional drive mechanism moves the receiving and fixing parts into the main frame, retracting the receiving part into the main frame and moving the fixing part away from the workshop floor. This allows the lifting platform to move. After the receiving part is retracted into the main frame, the platform height can be lowered during transfer, allowing personnel to better observe the road conditions ahead while pushing the platform. The height of the receiving part can be manually observed to determine its operational status. This system simultaneously secures the lifting platform and raises the receiving part, reducing the cumbersome process of fixing the platform within the workstation. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1-5 As shown, this utility model provides an automatic pallet loading and unloading platform, including a robot arm 1 and a lifting platform 2. The robot arm 1 is used to place or remove pallets on the lifting platform 2. The lifting platform 2 includes a main frame 21, a receiving part 22 and a fixing part 23. The main frame 21 is provided with pulleys 211 at the bottom and a movable opening 212 at the top. A bidirectional drive mechanism 3 is provided inside the main frame 21. One output end of the bidirectional drive mechanism 3 is used to drive the receiving part 22 to move up and down within the movable opening 212, and the other output end is used to drive the fixing part 23 to slide through the bottom of the main frame 21, so that the fixing part 23 abuts against or moves away from the workshop floor.

[0023] Furthermore, such as Figures 1-5 As shown, the bidirectional drive mechanism 3 includes a drive component 31 and a main shaft 32. The drive component 31 drives the main shaft 32 to move. The main shaft 32 is rotatably connected to two lifting rods 321, one of which is rotatably connected to the bottom of the receiving part 22, and the other is rotatably connected to the top of the fixing part 23. At least two sets of bidirectional drive mechanisms 3 are provided, and each bidirectional drive mechanism 3 is symmetrically distributed. A gear 322 is rotatably connected to the main shaft 32, and the gear 322 meshes with a guide toothed plate 323, which is fixedly installed inside the main frame 21.

[0024] Specifically, such as Figures 1-5As shown, the main shaft 32 is provided with at least two sets of lifting rods 321. Each set of lifting rods 321 includes a lifting rod 321 rotatably connected to the receiving part 22 and a lifting rod 321 rotatably connected to the fixing part 23. When the main shaft 32 is pushed by the driving member 31, the included angle between the two lifting rods 321 increases, thereby increasing the distance between the receiving part 22 and the fixing part 23, thus simultaneously bringing the fixing part 23 against the workshop floor and exposing the receiving part 22 to the movable opening 212. When the main shaft 32 is pulled by the driving member 31, the included angle between the two lifting rods 321 decreases, thereby shortening the distance between the receiving part 22 and the fixing part 23, thus simultaneously moving the fixing part 23 away from the workshop floor. The receiving part 22 is retracted into the movable opening 212 on the workshop floor, which facilitates movement. In addition, when the driving part 31 pushes the main shaft 32 to move, the gear 322 rotates simultaneously and meshes with the guide tooth plate 323. The guide tooth plate 323 supports the main shaft 32. It is worth noting that the main shaft 32 is provided with a groove for mounting the gear 322. The two sides of the gear 322 are limited to the inner walls of the groove, which can better maintain stability when the gear 322 rotates. The guide tooth plate 323 can be connected and fixed to the main frame 21 through an L-shaped support plate. The vertical part of the support plate is fixedly installed in the main frame 21, and the horizontal part is fixedly installed in the guide tooth plate 323.

[0025] In other embodiments, the two ends of the main shaft 32 are connecting ends 320, each of which is driven by a driving member 31. The driving member 31 pushes the connecting ends 320 to drive the main shaft 32, thereby achieving the lifting effect of the receiving part 22 and the fixing part 23.

[0026] It is worth noting that the drive component 31 can be a lead screw drive structure, or a cylinder, linear guide, etc., which are existing technologies and will not be described in detail here.

[0027] Furthermore, such as Figures 1-5 As shown, the main frame 21 is provided with a first lifting frame 213 and a second lifting frame 214. The first lifting frame 213 and the second lifting frame 214 are rotatably connected to each of the lifting rods 321. The first lifting frame 213 is used to support the receiving part 22, and the second lifting frame 214 is used to install the fixing part 23. The first lifting frame 213 and the second lifting frame 214 form a sliding part 210. The main frame 21 is provided with a guide ring 24 that slides with the sliding part 210. The main frame 21 is provided with a guide rod 241. The upper and lower ends of the guide rod 241 pass through the first lifting frame 213 and the second lifting frame 214 respectively, and slide with the first lifting frame 213 and the second lifting frame 214.

[0028] Specifically, such as Figures 1-5As shown, the first lifting frame 213 and the second lifting frame 214 support and fix the receiving part 22 and the fixing part 23 respectively. In some embodiments, the structure of the first lifting frame 213 and the second lifting frame 214 is composed of two sliding parts 210 and a connecting part for connecting the two sliding parts 210. The connecting part is rotatably connected to the lifting rod 321, and the sliding parts 210 slide with the guide rod 241, making the receiving part 22 and the fixing part 23 more linear during lifting and lowering. At the same time, a guide rod 241 is provided in the main frame 21. The upper and lower ends of the guide rod 241 slide with the first lifting frame 213 and the second lifting frame 214 respectively, further improving the guiding effect. In some embodiments, the guide rod 241 can be set in the middle of the main frame 21 to supplement the guiding function of the middle of the first lifting frame 213 and the second lifting frame 214, achieving a better linear movement effect.

[0029] Furthermore, such as Figures 1-5 As shown, the fixing part 23 includes several support feet. Specifically, when the driving member 31 pushes or pulls the main shaft 32 to move, the second lifting frame 214 is driven to descend or rise through the lifting rod 321, so that the support feet contact or move away from the workshop floor, thereby achieving the effect of fixing the main frame 21.

[0030] Furthermore, such as Figures 1-5 As shown, a movable position 4 is formed within the movable opening 212, and limiting portions 41 are provided at both the upper and lower ends of the movable position 4. Specifically, when the receiving part 22 is in the working state, the driving member 31 drives the receiving part 22 to rise, and the top surface of the receiving part 22 abuts against the limiting portion 41 at the upper end of the movable position 4. When the receiving part 22 is in the stopped state, the driving member 31 drives the receiving part 22 to fall, and the ground of the receiving part 22 abuts against the limiting portion 41 at the lower end of the movable position 4, thereby achieving a limiting effect.

[0031] Furthermore, such as Figures 1-5 As shown, a control module 20 is provided on the side of the main frame 21 for controlling the bidirectional drive mechanism 3.

[0032] The following is a detailed explanation of the working principle of this utility model; The lifting platform 2 is moved by pulleys 211. In use, the lifting platform 2 is pushed to the workstation, and the bidirectional drive mechanism 3 simultaneously drives the receiving part 22 and the fixing part 23 to move towards the upper and lower ends of the main frame 21. Ultimately, the receiving part 22 is exposed outside the movable opening 212, and the fixing part 23 abuts against the workshop floor, thus fixing the lifting platform 2 within the workstation. The robot arm 1 places or removes a pallet onto the top surface of the receiving part 22. During movement, the bidirectional drive mechanism 3 drives the receiving part 22 and the fixing part 23 into the main frame 21, causing the receiving part 22 to move. 2. The receiving part 22 is retracted into the main frame 21, and the fixing part 23 is away from the workshop floor to realize the movement of the lifting platform 2. After the receiving part 22 is retracted into the main frame 21, the height of the lifting platform 2 can be reduced when the lifting platform 2 is transferred, so that the personnel can better observe the road conditions in front of the lifting platform 2 when pushing the lifting platform 2. The height of the receiving part 22 can be manually observed to determine whether the receiving part 22 is in working condition, and the fixing of the lifting platform 2 and the lifting of the receiving part 22 can be realized at the same time, reducing the extra process of fixing the lifting platform 2 in the work position.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
