[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example: Figure 1 As shown, a cylindrical battery sealing production line includes a frame 1, with a mounting plate 11 on the top of the frame 1. A conveyor line is provided on the mounting plate 11. The conveyor line includes a conveyor line bracket 21 and a conveyor chain 22 provided on the conveyor line bracket 21. The conveyor chain 22 is mounted on a sprocket, which is driven by a motor. Multiple battery fixtures 23 are provided at equal intervals on the conveyor chain 22. During conveying, the battery is placed inside the battery fixture.

[0025] In this embodiment, a sealing mechanism 3, a sealing plane shaping mechanism 4, and a sealing plane detection mechanism 5 are arranged sequentially along the conveying direction of the conveyor line. The sealing mechanism 3 seals the battery, and the sealing plane detection mechanism 5 detects the flatness of the seal.

[0026] In this invention, a sealing plane shaping mechanism 4 is configured between the sealing mechanism 3 and the sealing plane detection mechanism 5 to flatten the sealing of the cylindrical battery, making the battery sealing more flat, improving the product qualification rate during subsequent testing, and reducing the waste of raw materials.

[0027] Specifically, such as Figure 2 As shown, the sealing mechanism 3 includes a sealing frame 31 and a sealing punch 32 mounted on the sealing frame 31. The sealing punch 32 has a sealing head 33 and also includes a sealing support 34 mounted below the sealing head 33. The sealing support 34 is vertically connected to the sealing frame 31 and is driven by a lifting drive mechanism mounted on the sealing frame 31. The lifting drive mechanism can be a cylinder.

[0028] The sealing frame 31 includes a base plate 311 connected to the mounting plate 11 and a vertical plate 312 connected to the base plate 311. The sealing punch 32 is fixedly connected to the vertical plate 312. The vertical plate 312 is also provided with a vertical guide groove, in which a slider connected to the sealing support 34 and capable of sliding up and down is engaged. The piston rod of the lifting drive mechanism is connected to the slider. Due to the viewing angle, the lifting drive mechanism is obscured by the vertical plate 312 and cannot be seen. During the sealing operation, the cylinder actuates, causing the sealing support 34 to rise and press against the bottom of the battery fixture. At the same time, the sealing punch 32 operates, and its sealing pressure head 33 acts on the sealing head of the battery to complete the sealing.

[0029] like Figure 3As shown, the sealing plane shaping mechanism 4 includes a shaping frame 41, a shaping pressure head 42, and a shaping support 43. The shaping frame 41 is equipped with a second lifting drive mechanism 44 that can drive the shaping pressure head 42 to rise and fall. The second lifting drive mechanism can be a cylinder, and the shaping pressure head 42 can be directly fixedly connected to the cylinder piston rod. The shaping support 43 is located below the shaping pressure head 42 and can be lifted and lowered on the shaping frame 41. It is driven by a third lifting drive mechanism 45 located on the shaping frame 41. To enable the shaping support 43 to be lifted and lowered, a vertical guide rail can be provided on the shaping frame 41, and the shaping support 43 is installed on the vertical guide rail by a sliding block.

[0030] The shaping frame 41 includes a base plate 411 connected to the mounting plate 11 and a vertical plate 412 connected to the base plate 411. The lifting drive mechanism 44 is mounted on the vertical plate 412. Figure 4 As shown, the bottom of the shaping support 43 is fixed with a force-bearing block, the force-bearing block has a force-bearing inclined surface, and the lifting drive mechanism 45 includes a drive block 47 with a drive inclined surface and a drive cylinder connected to the drive block 47, with the force-bearing inclined surface pressing on the drive inclined surface.

[0031] During the shaping process, the driving cylinder moves, and through the force transmission between the driving block and the force-bearing block, the shaping support 43 rises and presses against the bottom of the battery fixture. At the same time, the shaping pressure head 42 acts on the battery end cap to flatten the cylindrical battery seal, making the battery seal smoother.

[0032] In this embodiment, as Figure 5 As shown, the sealing plane detection mechanism 5 includes a detection frame 51. The detection frame 51 includes a base plate 3 511 connected to the mounting plate 11, a horizontal plate 512 disposed above the base plate 3 511, and a vertical plate 3 513 disposed on the horizontal plate 512. The base plate 3 511 and the horizontal plate 512 are connected by a connecting rod. A clamping block 1 52 and a clamping block 2 53 are movably disposed on the horizontal plate 512. The clamping block 1 52 and the clamping block 2 53 can be driven by a cylinder. The mechanism also includes a plurality of displacement probes 54 and a probe mounting plate 55 for mounting the probes 54. The probe mounting plate 55 is movably mounted on the vertical plate 3 513 and is driven by a lifting drive mechanism 4. The lifting drive mechanism 4 can be a cylinder. To enable the probe mounting plate 55 to be movably mounted on the vertical plate 3 513, a vertical guide rail can be installed on the vertical plate 3 513. The probe mounting plate 55 is mounted on the vertical guide rail by a sliding block. It also includes a vertical support block 56 located below the probe 54, and a lifting drive mechanism 5 for driving the vertical support block 56 to rise and fall. The lifting drive mechanism 5 can be a cylinder, and the vertical support block 56 can be directly connected to the piston rod of the cylinder. The horizontal plate 512 is provided with a clearance hole for the vertical support block 56.

[0033] During the inspection, the battery fixture is placed above the horizontal plate 512 and between clamping block 52 and clamping block 53. At this time, the vertical support block 56 rises and supports the bottom of the battery fixture. Meanwhile, clamping block 52 and clamping block 53 clamp the battery from both sides. The probe 54 descends under the action of the lifting drive mechanism and acts on the battery end cap to inspect the end cap at the seal.

[0034] Preferably, a short-circuit detection mechanism 6 is installed in the conveying direction of the conveyor line, located after the sealing plane detection mechanism 5, to perform battery short-circuit detection on the sealing production line, which is convenient and efficient. Figure 6 As shown, the short-circuit detection mechanism 6 includes a base plate 61 connected to the mounting plate 11, a vertical plate 62 connected to the base plate 61, a positive electrode detection head 63, a negative electrode detection head 64, a lifting drive mechanism 6 connected to the positive electrode detection head 63 and a lifting drive mechanism 7 connected to the negative electrode detection head 64, both mounted on the vertical plate 62. Both the lifting drive mechanism 6 and the lifting drive mechanism 7 can be cylinders. During short-circuit detection, the negative electrode detection head 64 rises under the action of the lifting drive mechanism 7 and contacts the negative electrode of the battery, while the positive electrode detection head 63 descends under the action of the lifting drive mechanism 6 and acts on the positive electrode of the battery.

[0035] To ensure the reliability and accuracy of battery short-circuit detection, a dust removal mechanism 7 is also included, positioned along the conveying direction of the conveyor line. Figure 7 As shown, the dust removal mechanism 7 prevents dust on the battery from affecting the accuracy of the test. The dust removal mechanism 7 includes a liftable dust removal hood 71 with a negative pressure suction port, which is disposed above the conveyor chain 22, and a lifting cylinder 72 connected to the dust removal hood 71. The lifting cylinder 72 is connected to the mounting plate 11. In this embodiment, the dust removal mechanism 7 is provided on the front side of the sealing mechanism 3, the front side of the sealing plane shaping mechanism 4, and the front side of the sealing plane detection mechanism 5.
