Description

Technical Field

[0001] The utility model relates to the technical field of lithium-ion battery equipment, in particular to a device for cleaning foreign matter and dust from a tray in a logistics system. Background Art

[0002] Under normal circumstances, the pallets in the logistics system contain foreign matter and dust. When the batteries are reloaded in the return assembly workshop, it is necessary to ensure that there are no foreign matter and dust in the pallets. If there is dust and foreign matter, it may cause the battery cells to be dirty and require a full inspection and wiping. Severe large particles of foreign matter may cause the battery cells to be uneven inside the pallet, causing abnormalities in the equipment clamps and mechanical failures. Entering the equipment for charging and discharging may cause the pin points to bend, and even worse, cause the positive and negative poles of the battery cells to short-circuit, creating fire risks and hidden dangers, resulting in safety accidents.

[0003] Currently, there are no commercially available products or structures suitable for removing foreign matter from pallets in chemical logistics systems. Lithium battery production workshops repeatedly encounter foreign matter trapped in pallets. Without an effective device for removing foreign matter from finished products, the problem can only be detected by the battery's condition within the pallet and the equipment's pressure test. Once the equipment detects an abnormality, the presence of foreign matter is detected, which then poses a safety risk and requires manual intervention. Therefore, it is urgent to design a device that can flip and remove large foreign matter from pallets and blow air to remove contaminants from them. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a device for cleaning foreign matter and dust from pallets in a logistics system, which can flip the pallet and remove large foreign matter particles in the pallet, and blow air to clean the pallet to avoid safety accidents.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a device for cleaning foreign matter and dust from pallets in a logistics system, comprising a pallet clamping mechanism, a flipping and tipping mechanism, and an air blowing mechanism. The action portion of the flipping and tipping mechanism is connected to the pallet clamping mechanism, and the flipping and tipping mechanism drives the pallet clamping mechanism to move back and forth between a standby avoidance position and a lifting and tipping position. The blowing end of the air blowing mechanism is directed toward the lifting and tipping position, and the blowing mechanism blows air toward the pallet clamped by the pallet clamping mechanism in the lifting and tipping position to clean it. The flipping and tipping mechanism clamps, lifts, and flips the pallet being transported on the logistics system, while the air blowing mechanism blows air onto the pallet to fully clean it. After cleaning, the flipping and tipping mechanism lowers the pallet back to the logistics system for continued transportation.

[0006] As an optional technical solution, the blowing mechanism includes an air source mechanism and an air blowing control mechanism. The air blowing control mechanism is arranged at the air outlet port of the air source mechanism and controls the air source mechanism to switch between a blowing state and a standby state.

[0007] As an optional technical solution, the outlet port of the air blowing control mechanism is equipped with an air guide tube, which can be a flat-nosed tube or a shaped hose with a flat nozzle at the outlet. This facilitates adjusting the blowing direction of the air blowing mechanism and expands the blowing range, achieving thorough cleaning of the pallet.

[0008] As an optional technical solution, the flipping and tipping mechanism includes a tipping drive member, which includes a vertical drive member, a horizontal drive member and a rotary drive member. The action part of the vertical drive member is connected to the horizontal drive member and the vertical drive member drives the horizontal drive member to move up and down. The action part of the horizontal drive member is connected to the rotary drive member and the horizontal drive member drives the rotary drive member to move horizontally. The action part of the rotary drive member is connected to the tray clamping mechanism and the rotary drive member drives the tray clamping mechanism to rotate.

[0009] As an optional technical solution, the tipping drive member is arranged on the machine platform, and a vertical guide mechanism is arranged on the machine platform. The vertical guide mechanism includes a vertical guide rod and a vertical slider. The vertical guide rod is arranged on the machine platform, and the vertical slider is arranged on the vertical guide rod and moves along the vertical guide rod. The action part of the vertical drive member is provided with a vertical moving platform, the vertical moving platform is connected to the vertical slider and the horizontal drive member is arranged on the vertical moving platform.

[0010] As an optional technical solution, the pallet clamping mechanism includes a pallet claw, and the flipping and dumping mechanism includes two dumping drive members. The two dumping drive members are symmetrically arranged and a pallet conveyor installation position is reserved between them. The action part of the rotating drive member of each dumping drive member is provided with a pallet claw.

[0011] As an optional technical solution, the vertical driving member is a rodless cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The flipping and dumping mechanism in the present invention drives the pallet clamping mechanism to lift and flip the pallet 180 degrees, so that large particles of debris in the pallet fall under the action of gravity. When the pallet is lifted and flipped, the blowing mechanism blows air to the pallet to remove dust adhering to the inside and bottom of the pallet, reducing the abnormality caused by the unstable placement of battery cells in the pallet due to the presence of foreign matter in the pallet, and reducing the risk of fire; 2. The present invention can be used in conjunction with a logistics system. After being connected to the control system of the logistics system, it can cooperate with the logistics system to realize automatic cleaning of the pallet, reducing the labor intensity of personnel.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative work are within the scope of protection of the present invention. Example

[0018] like Figure 1 As shown, a device for cleaning foreign matter and dust from pallets on a logistics system includes a pallet clamping mechanism 1, a flipping and dumping mechanism 2 and a blowing mechanism 3. The flipping and dumping mechanism 2 is arranged at a position corresponding to the pallet conveying line of the logistics system, and the action part of the flipping and dumping mechanism 2 is connected to the pallet clamping mechanism 1. The pallet clamping mechanism 1 is a tooling suitable for grabbing pallets, and the flipping and dumping mechanism 2 drives the pallet clamping mechanism 1 to move back and forth between a standby avoidance position and a lifting and dumping position. When the pallet clamping mechanism 1 is in the standby avoidance position, the pallet clamping mechanism 1 is located at the side position of the pallet conveying line of the logistics system and does not affect the logistics system from conveying pallets. The logistics system can convey pallets through the pallet clamping mechanism 1. When the pallet to be cleaned is conveyed by the logistics system to a position suitable for being grasped by the pallet clamping mechanism 1, the flipping and dumping mechanism 2 drives the pallet clamping mechanism 1 to move to grasp the pallet, and drives the pallet clamping mechanism 1 and the grasped pallet to lift and flip 180°. The pallet stays for a period of time so that the residual particles and other debris in it fall under the action of gravity.

[0019] The blowing mechanism 3 is used to blow air to clean the pallet. The blowing end of the blowing mechanism 3 is directed toward the lifting and dumping position. When the pallet clamping mechanism 1 is in the lifting and dumping position, the pallet clamped by the pallet clamping mechanism 1 is within the blowing range of the blowing mechanism 3. The blowing mechanism 3 blows air to clean the pallet clamping mechanism 1 and the clamped pallet to remove dust and other foreign matter adhering to the pallet.

[0020] In addition, when the flipping and tipping mechanism 2 drives the pallet clamping mechanism 1 and the clamped pallet to move, the blowing mechanism 3 can continue to work to blow and clean part of the outer wall of the pallet.

[0021] The blowing mechanism 3 includes an air source mechanism and an air blowing control mechanism. The air source mechanism is a compressed air source device. The air blowing control mechanism includes an electromagnetic valve and a PLC control system adapted to the electromagnetic valve. The electromagnetic valve is arranged at the air outlet port of the air source device. The state of the electromagnetic valve is controlled by the PLC control system to realize the control of the air source mechanism. When the PLC system controls the solenoid valve to be in the open state, the air source mechanism is in the blowing state, and the air blowing mechanism 3 blows air toward the lifting and dumping position. When the PLC system controls the electromagnetic valve to be in the closed state, the air source device is in the standby state, and the blowing system does not blow air outward.

[0022] In order to facilitate the adjustment and control of the blowing direction of the blowing mechanism 3, the air outlet port of the blowing control mechanism, that is, the air outlet port of the solenoid valve, is provided with an air guide pipe. The air guide pipe is connected to the air outlet port of the solenoid valve and guides the air blown by the air source mechanism to a specified position. The air guide pipe can be a flat-mouthed pipe. The use of a flat-mouthed pipe is conducive to improving the blowing coverage range of the blowing mechanism 3, thereby realizing all-round blowing cleaning of the pallet. The air guide pipe can also be a shaped hose with a flat mouth at the blowing port. The use of a shaped hose facilitates the adjustment of the shape of the air guide pipe, thereby facilitating the adjustment of the blowing direction of the blowing mechanism 3.

[0023] See also Figure 1 and Figure 2 The flipping and tipping mechanism 2 includes a tipping drive component, which includes a vertical drive component 21, a horizontal drive component 22 and a rotation drive component 23.

[0024] In some embodiments, the actuating portion of the vertical drive member 21 is connected to the transverse drive member 22, and the vertical drive member 21 drives the transverse drive member 22 to move up and down. The actuating portion of the transverse drive member 22 is connected to the rotary drive member 23, and the transverse drive member 22 drives the rotary drive member 23 to move laterally. The actuating portion of the rotary drive member 23 is connected to the pallet clamping mechanism 1, and the rotary drive member 23 drives the pallet clamping mechanism 1 to rotate. The main function of the transverse drive member 22 is to drive the pallet clamping mechanism 1 close to the pallet being transported by the logistics system, so that the pallet clamping mechanism 1 moves to a position where it can clamp the pallet or return the pallet to the logistics system; the function of the vertical drive member 21 is to drive the pallet clamping mechanism 1 that clamps the pallet to rise or fall; and the function of the rotary drive member 23 is to drive the pallet clamping mechanism 1 that clamps the pallet to rotate. Under the linkage cooperation of the vertical drive member 21, the horizontal drive member 22 and the rotary drive member 23, the pallet clamping mechanism 1 can start moving from the standby avoidance position, clamp, lift and flip over the pallet transported by the logistics system, and the pallet clamping mechanism 1 can also start moving from the lifting and dumping position, reverse and reset the pallet in the lifted and flipped state and place it on the logistics system.

[0025] Furthermore, the device of this embodiment also includes a machine platform 24, and the tipping drive member is arranged on the machine platform 24. The machine platform 24 is arranged on one side of the logistics system and serves as an installation base for the tipping drive member. The vertical drive member 21 is arranged on the machine platform 24, and the horizontal drive member 22, the rotation drive member 23, the tray clamping mechanism 1, etc. are all installed on the action part of the vertical drive member 21. In order to reduce the load of the vertical drive member 21 and limit the moving direction of each component installed in the action part of the vertical drive member 21, a vertical guide mechanism 25 is also provided on the machine platform 24. The vertical guide mechanism 25 includes a vertical guide rod and a vertical slider. The vertical guide rod is arranged on the machine table 24. The vertical guide rod is parallel to the driving direction of the vertical driving member 21. The vertical slider is arranged on the vertical guide rod and moves along the vertical guide rod. The vertical slider can be a linear bearing installed on the vertical guide rod. The action part of the vertical driving member 21 is provided with a vertical moving platform. The vertical moving platform is connected to the vertical slider. The vertical driving member 21 drives the vertical moving platform to move up and down along the direction limited by the vertical guide rod. The horizontal driving member 22 is arranged on the vertical moving platform.

[0026] The vertical driving member 21 can be a rodless cylinder, which is used in conjunction with the vertical guide mechanism 25 to drive the horizontal driving member 22, the rotary driving member 23, the tray clamping mechanism 1 and the tray to move stably up and down.

[0027] The machine platform 24 is provided with a side end plate, and the side end plate is provided with a mounting hole. The air guide pipe of the blowing mechanism 3 can be set through the mounting hole to achieve fixation of the air guide pipe.
