The dry cell jelly defect visual inspection apparatus according to claim 1, wherein The inclination detection member comprises a movable guide rail (22) mounted on one side of the swing connecting plate (31), the inner side of the movable guide rail (22) is slidably connected with a bayonet (34), the end of the bayonet (34) away from the swing connecting plate (31) is mounted with a pull rod (33), one side of the pull rod (33) is provided with an extension rod (21), the top of the base (1) is mounted with a threaded rod (15) located on one side of the guide column (2), the threaded rod (15) is sleeved with a movable sleeve frame (18), one side of the top of the movable sleeve frame (18) is mounted with a telescopic cylinder (19), the output end of the telescopic cylinder (19) is connected with a connecting plate (20) connected with the extension rod (21), one side of the pull rod (33) away from the bayonet (34) is mounted with an indicating mark (30), one side of the side connecting seat (4) is mounted with an angle measuring clasp (29) located outside the indicating mark (30).

7. The apparatus for visual inspection of the defects of the paste layer of the dry cell according to claim 6, wherein The diameter of the bayonet (34) is equal to the width of the inner wall of the movable guide rail (22).

8. The dry cell jelly defect visual inspection apparatus according to claim 6, wherein The swing connecting plate (31) and the side connecting seat (4) are rotationally connected through the rotating shaft, the rotation center of the movable guide rail (22) is coaxial with the rotation center of the swing connecting plate (31), and the movable guide rail (22) is aligned with the swing connecting plate (31).

9. A method for visually detecting a defect of a dry cell jelly layer, characterized by, The dry battery pulp layer defect visual detection equipment of any one of claims 1-8 comprises the following steps: S1: according to the size of the pulp layer paper to be detected, the synchronous distance adjusting member is operated to make the size of the rectangle surrounded by the limiting plates (10) on the observation table (3) equal to the size of the pulp layer paper, and in this process, the visual detector main body (13) is raised or lowered with the movement of the limiting plates (10) through the operation of the synchronous distance adjusting member; S2: when the limiting plates (10) move away from the center of the observation table (3), it indicates that the pulp layer paper is larger, at this time, the visual detector main body (13) is raised under the action of the synchronous distance adjusting member, so as to increase the shooting range of the visual detector main body (13), and similarly, if the pulp layer paper is smaller, the distance between the visual detector main body (13) and the observation table (3) is shorter; S3: the pulp layer paper is placed in the rectangle surrounded by the limiting plates (10), so that the edge of the pulp layer paper is attached to the limiting plates (10), and then the visual detector main body (13) is used to shoot the pulp layer paper attached to the limiting plates (10) in the vertical direction; S4: the shooting angle of the visual detector main body (13) is adjusted by the inclination detection member, so as to make the visual detector main body (13) shoot the pulp layer paper at different angles.
