Description

Technical Field

[0001] The utility model relates to the technical field of mechanical conveying equipment, and particularly relates to a tray return box. Background Art

[0002] During the processing of batteries, electrolytic solution will adhere to the trays for holding the batteries. Therefore, after the battery processing, the electrolytic solution on the trays needs to be cleaned before the trays can re-enter the battery processing station.

[0003] The prior art discloses a Chinese invention patent with the publication number of CN116393471B and the patent name of a battery tray cleaning device. It specifically discloses a tray feeding conveyor line, a tray support roller return conveyor line, a tray discharging conveyor line, a tray loading manipulator, a tray discharging manipulator, and a drying mechanism. The tray support roller return conveyor line is composed of an ultrasonic roller conveyor line, a drying roller conveyor line, a drying roller conveyor line, and a tray return roller conveyor line. Tray support transfer mechanisms are provided at the output ends of the ultrasonic roller conveyor line, the drying roller conveyor line, the drying roller conveyor line, and the tray return roller conveyor line. The drying mechanism is arranged on the drying roller conveyor line, and a plurality of ultrasonic cleaning tanks are arranged at intervals on the ultrasonic roller conveyor line.

[0004] The above solution uses a circulating return conveyor line to convey the tray supports. Multiple trays can be arranged and placed on the tray supports, and they do not need to be separated from the tray supports during the cleaning, drying, and drying processes, enabling batch cleaning, drying, and drying of multiple trays in multiple columns, with high cleaning efficiency.

[0005] However, in the actual use process, when the trays are separated from the battery processing production line, external air will enter the battery processing production line. Since there is a certain amount of moisture in the air, the moisture will enter the battery processing production line during the process of the trays entering and leaving, affecting the processing quality of the batteries in the battery processing production line.

[0006] Therefore, a tray return box is proposed to solve the above-mentioned problems. Utility Model Content

[0035] The present utility model will be further described below in conjunction with embodiments.

[0036] Embodiment:

[0037] This case proposes a tray return box. Refer to the attached Figures 1-5 , which mainly includes a box body 1. The interior of the box body 1 is hollow, and a tray inlet 2 and a tray outlet 3 are provided on the box body 1. In this case, a battery processing station is connected to the rear side of the tray inlet 2. After processing, the tray will enter the interior of the box body 1 from the tray inlet 2. The separation of the tray and the battery is a well-known technology and will not be elaborated here.

[0038] A nitrogen injection pipe 10 and an air extraction pipe 11 are provided at the upper end of the box body 1. When the tray enters the interior of the box body 1, the air extraction pipe 11 extracts the air inside the box body 1 and fills nitrogen into the nitrogen injection pipe 10, thereby reducing the air specific gravity inside the box body 1 and further preventing the moisture in the air from entering the battery processing station through the tray inlet 2 and affecting the processing quality of the battery.

[0039] And a vertically liftable movable plate 4 is provided inside the box body 1. Two fixed panels 41 are respectively vertically provided on both sides of the upper end of the movable plate 4. A transmission belt 42 is respectively provided on the corresponding end faces of the two fixed panels 41. The transmission direction of the transmission belt 42 is set facing the tray inlet 2. The two transmission belts 42 are synchronously driven by two connecting rollers. When the tray entering the box body 1 touches the transmission belt 42, it will directly fall above the transmission belt 42, and at this time, the transmission of the transmission belt 42 is stopped.

[0040] Two parallel transfer belts 5 are also arranged in the box body 1. The movable plate 4 is located between the two transfer belts 5, and the driving direction of the transfer belt 5 is set facing the tray outlet 3.

[0041] In this case, a tray cleaning structure can be arranged on one side of the tray outlet 3 of the box body 1, and the cleaned tray is then conveyed back into the battery processing station. This is a well-known technology and will not be elaborated here too much, nor is it shown in the drawings.

[0042] In this case, a telescopic push rod 13 is arranged at the lower end of the box body 1. The telescopic push rod 13 is provided with two output shaft ends, and the two output shaft ends are connected to the bottom end of the movable plate 4 for controlling the up and down lifting of the movable plate 4.

[0043] It should be noted that the height of the tray inlet 2 in this case is higher than the height of the tray outlet 3. When the tray reaches the conveyor belt 42, at this time, the telescopic push rod 13 makes its output shaft end drive the movable plate 4 to descend, and the height of the transfer belt 5 is flush with the tray outlet 3. When the movable plate 4 descends, the tray on the conveyor belt 42 will "rest" on the transfer belt 5. At this time, start the transfer belt 5 to drive, and convey the tray out of the box body 1 through the tray outlet 3.

[0044] In this case, in order to keep the trays entering the conveyor belt 42 level and correct the placement angle of the trays, a number of equally spaced rollers 43 are respectively arranged at the upper ends of each fixed panel 41. When the tray passes through the roller 43 arrays on both sides of it, it is ensured that the tray is directly above the conveyor belt 42 and perpendicular to the transfer belt 5.

[0045] Optionally, a transition bin 6 is arranged at the side end of the box body 1. The tray outlet 3 is arranged at one end of the transition bin 6 far from the box body 1. A vertically liftable sealing door 61 is arranged at one end of the transition bin 6 facing the box body 1. When the tray is conveyed on the conveyor belt 42, the sealing door 61 is opened. When the tray leaves the sealing door 61, at this time, air will enter the box body 1 through the sealing door 61. After closing the sealing door 61, the air extraction pipe 11 extracts the air inside the box body 1, and nitrogen is injected into the box body 1 through the nitrogen injection pipe 10 to reduce the air specific gravity inside the box body 1, thereby avoiding the moisture in the air entering the battery processing station through the tray inlet 2 and affecting the processing quality of the battery.

[0046] It is worth noting that a safety valve 7 is arranged at the upper end of the box body 1 in this case. When the internal pressure of the box body 1 is too high, the safety valve 7 can release the internal pressure of the box body 1 to avoid potential safety hazards.

[0047] A dew point meter 8 for detecting the dew point value inside the box body 1 is arranged at the upper end of the box body 1. In practice, ensure that the dew point value inside the box body 1 is about -40°C.

[0048] A pressure gauge 9 is provided at the upper end of the box body 1 for monitoring the real-time pressure value inside the box body 1.

[0049] In order to prevent the pallet from being misaligned or jammed during transmission inside the box body 1, an observation window 13 is hinged at one end of the box body 1 away from the pallet inlet 2, so as to facilitate the staff to observe in real time.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the present invention in each embodiment.
