TECHNICAL FIELD

[0001] The present application relates to the technical field of battery code spraying equipment, in particular to a polymer battery automatic code spraying equipment. BACKGROUND

[0002] In the production process of large polymer batteries, the code spraying equipment used is composed of a common belt conveying line and a code spraying machine. At least two employees are needed to operate the code spraying equipment. One employee needs to place the batteries in the tray one by one onto the conveying line, and the other employee needs to receive the batteries at the other end of the conveying line and place them one by one into the finished product tray.

[0003] The currently used equipment has low production efficiency. Since the loading and unloading are manual, it is particularly easy to cause the batteries to fall off, resulting in waste products, and batch mixing often occurs. When a single battery flows on the conveying line, it can also cause wear and tear on the appearance of the battery, also resulting in waste products. SUMMARY

[0010] The lower feeding station comprises a horizontally arranged lower feeding tray transfer mechanism and a lower feeding tray lifting mechanism arranged above the lower feeding tray transfer mechanism, and the lower feeding tray lifting mechanism is located below the lower feeding mechanical arm.

[0011] The lower feeding tray transfer mechanism comprises two transmission belts arranged along the width direction, and the lower feeding tray lifting mechanism comprises a lifting plate arranged between the two transmission belts and vertically lifted by driving.

[0012] The upper feeding mechanical arm and the lower feeding mechanical arm have the same structure and can be horizontally moved by driving, and each of the upper feeding mechanical arm and the lower feeding mechanical arm comprises at least four clamping rods capable of clamping and placing the tray at the outer periphery, and the outer surface of the clamping rod forms a limiting groove.

[0027] In a preferred embodiment, the first coding mechanism 5 is located on one side of the coding transfer mechanism, and the second coding mechanism 6 is located on the opposite side of the coding transfer mechanism. Figure 2 The specific arrangement shown can be determined by the position of the battery cells on the tray, and is not limited to the position shown in this figure.

[0028] In one preferred embodiment, the pallet loading module and the pallet unloading module are symmetrically arranged, and the two parallel loading stations and the two parallel unloading stations are each symmetrically arranged with respect to the axis of the inkjet printing transfer mechanism.

[0029] In a preferred embodiment, the loading station includes a horizontally arranged loading pallet transfer mechanism 12 and a loading pallet lifting mechanism 14 arranged above the loading pallet transfer mechanism, with the loading pallet lifting mechanism located below the loading robot 3. When the loading pallet is moved to the inner side and stops by the loading pallet transfer mechanism, it stops above the tray of the pallet lifting mechanism 14. At this time, the pallet lifting mechanism 14 lifts the pallet and battery to a predetermined height, where the loading robot grabs them and moves them to the inkjet printing transfer mechanism for inkjet printing.

[0030] In addition, limit plates 11 are installed on the outside of the feeding station to limit the battery cells on the outside and prevent them from tipping over. The feeding side of the limit plate 11 is bent outward to form a flared feeding port for easy feeding.

[0031] In a preferred embodiment, the pallet loading and transfer mechanism includes a conveyor belt arranged along the width direction, and the pallet lifting mechanism includes a pallet 13 placed between the two conveyor belts and capable of vertical lifting and lowering.

[0032] The unloading station includes a horizontally arranged unloading pallet transfer mechanism and an unloading pallet lifting mechanism arranged above the unloading pallet transfer mechanism, with the lifting mechanism located below the unloading robot. This structure is the same as the loading pallet transfer mechanism and loading lifting structure of the loading station; please refer to the description of the structure of the loading pallet transfer mechanism and loading pallet lifting mechanism described above, and will not be repeated here.

[0033] In one preferred embodiment, the unloading pallet transfer mechanism includes a conveyor belt arranged along its width, and the unloading pallet lifting mechanism includes a pallet positioned between two of the conveyor belts and capable of vertical lifting and lowering under drive. This structure is the same as the loading lifting structure of the loading station; please refer to the description of the structure of the loading pallet lifting mechanism described above, and it will not be repeated here.

[0034] In one preferred embodiment, the loading and unloading robots have identical structures and are driven to move horizontally. Taking the loading robot as an example, it includes at least four clamping rods 32 capable of gripping and placing pallets around its periphery. Limiting grooves are formed on the outer surfaces of the clamping rods. The clamping rods 32 are mounted on the bottom of a mounting plate 31, which can be driven to move back and forth, thus causing the clamping rods 32 to move synchronously. When the clamping rods move above the loading station, they can pick up two pallets from the loading station and then move them onto the inkjet printing transfer mechanism.

[0035] In one preferred embodiment, the two ends of the inkjet printing transfer mechanism extend into the interior of the pallet loading module and the pallet unloading module. Two parallel loading stations are arranged below the corresponding sections of the inkjet printing transfer mechanism extending into the pallet loading module along their length direction. Two parallel unloading stations are arranged below the corresponding sections of the inkjet printing transfer mechanism extending into the pallet unloading module along their length direction.

[0036] In a preferred embodiment, the upper surface of the internal section of the inkjet printing transfer mechanism extending into the pallet loading module and the pallet unloading module is provided with limiting plates 41 on both sides along the axial direction, and the two limiting plates 41 at each end are arranged opposite to each other, such as... Figure 5 As shown.

[0037] During operation, the operator manually places several trays containing battery cells to be marked into the first loading station 1 and the second loading station 2. The loading robot 3 then sequentially places the trays from the first loading station 1 and the second loading station 2 onto the marking transfer mechanism 4, and marks the cells at the first marking mechanism 5 and the second marking mechanism 6.

[0038] After the coding is completed, the pallet is transferred to the unloading position by the coding transfer mechanism 4, and the unloading robot 9 grabs the pallet and places it at the first unloading station 7. After the first unloading station 7 is full of pallets, the unloading robot 9 transfers the pallet to the second unloading station 8. At the same time, the first unloading station 7 moves the full pallet out and is picked up manually.

[0039] The automatic inkjet printing equipment for polymer battery cells in this embodiment of the invention can replace manual loading with a robotic arm and can simultaneously print inkjet prints on an entire tray of batteries. It can replace the work that originally required 2-3 people with the work of 1 person. The automatic inkjet printing equipment for polymer battery cells in this embodiment of the invention can print inkjet prints on an entire tray of batteries, thereby improving production efficiency and reducing wear and tear on the batteries from the conveyor line.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0041] Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the 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 the equivalents of the claims be included within the invention.
