Description

Technical Field

[0001] The utility model relates to the technical field of short blade battery processing, in particular to a battery turning mechanism. Background Art

[0002] The size of the short blade battery (545×225×38mm) is about 40% shorter than that of traditional long batteries. This size reduction not only helps to improve the flexibility of battery packaging, but also reduces the overall volume and weight of the battery pack to a certain extent, thereby improving the vehicle's energy efficiency and endurance.

[0003] When processing short blade batteries, the pole surface on them needs to be printed. Because poles are set at both ends of the battery, after printing the pole surface on the upper end, the battery needs to be flipped 180° so that the pole on the lower end faces upwards before continuing printing. The existing flipping method is to manually remove the battery from the clamping fixture, manually flip it over, and then clamp it in the clamping fixture. This method, on the one hand, requires repeated disassembly and assembly, which makes the operation more cumbersome, prolongs the printing time, and reduces efficiency. On the other hand, repeated disassembly and assembly lead to large clamping errors, which will reduce the printing quality. Utility Model Content

DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0027] like Figure 1 、 Figure 2 As shown, a battery flip mechanism provided in this embodiment includes a fixing seat 1, a base plate 2, a lower supporting mechanism 3, a driving mechanism 4, a clamping plate 5, a positioning cam 6, a clamping plate 7, a universal wheel 8 and a rotating mechanism 9.

[0028] The mounting base 1 includes a mounting plate 11, a mounting seat 12, and a travel hole 13. The mounting plate 11 has an A side and a B side disposed opposite each other. The mounting seat 12 is fixed to the upper end of the mounting plate 11 on the B side. The mounting seat 12 is used to mount a linear drive mechanism to move components mounted on the mounting base 1 up and down, between the printing station and the flipping station. The flipping station is located below the printing station.

[0029] The mounting plate 11 is provided with a rotation mechanism 9, the end of which is connected to the base plate 2. The base plate 2 is located on the A side, and a universal wheel 8 is provided on one side of the base plate 2, which contacts the surface of the mounting plate 11. The driving mechanism 4 is provided on the other side of the base plate 2.

[0030] The lower support mechanism 3 includes an operating handle 31, a connecting frame 32 and a first slide rail 33. The connecting frame 32 includes a first plate 321, a second plate 322 vertically connected to one end of the first plate 321, and a third plate 323 connected between the first plate 321 and the second plate 322. The first slide rail 33 extends toward the base plate and is simultaneously connected between the mounting plate 11 and the first plate 321. The operating handle 31 is placed in the travel hole 13. One end of the operating handle 31 is connected to the first plate 321 by a screw 34, and the other end of the operating handle 31 extends to the outside of the mounting plate 11. The end of the second plate 322 away from the first plate 321 extends to the bottom of the clamping plate 5. The upper surface of the second plate 322 is connected to a clamping plate 7 and an insulating pad 324 corresponding to the position of the pole 101 of the battery 10. During operation, the insulating pad 324 contacts the surface of the pole 101, supporting the battery 10 through the lower support mechanism 3.

[0031] like Figure 3 As shown, a positioning cam 6 is provided on one side surface of the substrate 2 close to the fixing seat 1, and the positioning cam 6 is provided on the upper and lower sides of the substrate 2. A card slot 71 adapted to the positioning cam 6 is provided at the upper end of the card plate 7. The card slot 71 is an inverted U-shape with an open upper end, and the side walls forming the card slot 71 are elastic walls. When the operating handle 31 is pushed downward, the positioning cam 6 disengages from the card slot 71. At this time, the rotating mechanism 9 can be activated to drive the substrate 2 and the battery 10 clamped thereon to rotate. After rotating to 180°, the operating handle 31 is pushed upward so that the card slot 71 is engaged with the positioning cam 6 to achieve limiting. At this time, the insulating pad 324 is in contact with the pole 101 of the battery 10.

[0032] like Figure 4As shown, in this embodiment, the drive mechanism 4 includes a fixed plate 41, a spring 42, an unlocking plate 43, and a second slide rail 44. The second slide rail 44 is positioned on the base plate 2 in a direction perpendicular to the extension of the first slide rail 33. Two clamping plates 5 are connected to the second slide rail 44. One end of the fixed plate 41 is connected to the base plate 2, and the other end of the fixed plate 41 is connected to the spring 42, which abuts against the clamping plates 5. One end of the unlocking plate 43 passes through the fixed plate 41 and connects to the clamping plates 5. The other end of the unlocking plate 43 is provided with an unlocking hole 431. The fixed plate 41, spring 42, and unlocking plate 43 may be positioned adjacent to both clamping plates 5, or adjacent to only one clamping plate 5, with the other clamping plate 5 in a fixed position. A cylinder is positioned at the location corresponding to the unlocking hole 431, and a wedge is mounted on the telescopic rod of the cylinder. The cylinder is fixed to the mounting structure on the printing station and is not integral to the flipping mechanism.

[0033] During use, the battery 10 is placed between the two clamps 5. During this process, the spring 42 compresses until the battery 10 is in place. The elastic force of the spring 42 pushes the clamps 5 against the battery 10. To release the battery 10, the cylinder is activated and extended, inserting the wedge-shaped block of the cylinder's telescopic rod into the unlocking hole 431. During the insertion process, the unlocking plate 43 moves, causing the spring 42 to compress again. The unlocking plate 43 pulls the clamps 5 outward, releasing the battery 10. When the cylinder is withdrawn, the spring 42, freed from external force, reapplies its elastic force, pushing the clamps 5 outward.

[0034] In the second embodiment, the drive mechanism 4 includes a motor mounted on the fixing base 1, a screw connected to the motor, and a second slide rail 44 connected between the clamping plate 5 and the base plate 2. The screw is threadedly connected to both clamping plates 5. In this case, the motor is used to tighten and loosen the clamping force.

[0035] like Figure 2 As shown, the rotating mechanism 9 includes a rotating shaft 91 which is rotatably arranged on the fixing seat 1 through a bearing, one end of the rotating shaft 91 is connected to the base plate 2, and the other end of the rotating shaft 91 is provided with a gear 92. A rack 93 is provided at the rotating station. When it is necessary to flanging the battery 10, the linear drive mechanism on the mounting seat 12 is started to move the entire flipping mechanism down to the flipping station so that the gear 92 is engaged with the rack 93. The rack 93 is started to move laterally to rotate the gear 92, so that the base plate 2 and the battery 10 thereon are flipped 180°. The movement of the rack 93 is realized by a motor or a cylinder, and the stroke of the motor or cylinder is set in advance so that the gear 92 rotates 180° after one action of the rack 93.

[0036] During operation, first place the short blade battery 10 in the splint 5 and fix it. Start the linear drive mechanism on the mounting seat 12 to move the battery to the printing station, first plasma clean the surface of the pole 101, and then print the surface of the pole 101. After the surface pre-curing and final curing functional modules of the pole 101 are completed, start the linear drive mechanism on the mounting seat 12 to move the entire flipping mechanism down to the flipping station, the gear 92 is engaged with the rack 93, and the lower support mechanism 3 is moved down. The battery 10 flips 180° so that the bottom pole 101 on the battery 10 faces upward and the top pole 101 that has been printed faces downward. Move the lower support mechanism 3 upward so that the insulating pad 324 contacts the pole 101, and start the linear drive mechanism on the mounting seat 12 again to move the battery 10 to the printing station, and start the printer again to print. After printing is completed, start the cylinder to unlock the splint 5 and release the battery 10 offline. Repeat the above steps to print the next battery 10.

[0037] The battery flipping mechanism provided by the utility model can realize an assembly line type short blade battery pole surface printing mass production line.
