[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Reference Figures 1-2 The utility model provides a positioning device for full-automatic welding of cathode plate, including the table 2 for placing the plate spare and the base 1 for supporting the table 2, the included angle between the table 2 and horizontal plane forms the included angle greater than zero, and the plate spare to be positioned slides along the table 2, and the blocking structure 3 is arranged along the plate spare sliding path direction on the table 2, the blocking structure 3 is composed of two limit plates 31 forming the included angle, and the end of two limit plates 31 close to each other is swingly arranged on the table 2, and further including the locking mechanism 4 for limiting limit plate 31 and locking the included angle of two limit plates 31.

[0022] It can be understood that the base 1 is a component for tilting supporting the table 2, for example, can be a plurality of support rods of different lengths, can also be a top-tilted pedestal structure, but is not limited to this. The table 2 is a component for carrying and moving the plate, for example, can be a smooth panel structure on the top, can also be a plurality of universal balls uniformly distributed on the top of the table 2, but is not limited to this. The limit plate 31 is a component for guiding and positioning the plate, for example, can be a long strip plate structure, can also be a long strip structure composed of a plurality of rollers, but is not limited to this. The locking mechanism 4 is a component for locking the rotation angle of the limit plate 31, for example, can adopt a bolt locking structure or a shaft hole limiting structure, but is not limited to this. The swing of the limit plate 31 can be manual swing or automatic swing by a motor or a telescopic driving piece.

[0023] In this way, when in use, the plate is placed on the table 2, and the plate moves along the tilting direction of the table 2 and is finally positioned on the blocking structure 3. If the model or shape of the plate is changed, the edge and corner of the plate that needs to be positioned can be measured, and then the included angle of the two limit plates 31 is adjusted by swinging the limit plates 31 to correspond to the edge and corner of the plate, and then the position of the two limit plates 31 is locked by the locking mechanism 4, so as to lock the size of the included angle of the two limit plates 31. In this way, the included angle of the two limit plates 31 can be adjusted according to the angle of the side of the plate, so as to be suitable for plates of different shapes and improve the application range.

[0024] In some embodiments, reference Figures 2-3The angle end of the limiting plate 31 is provided with a rotating shaft 32 which is rotatably installed on the tabletop 2 and extends below the tabletop 2; the locking mechanism 4 comprises a swing lever 41 which is fixed at one end of the rotating shaft 32 extending below the tabletop 2, and a locking piece 42 which is arranged on the swing lever 41 and is locked and positioned at the bottom of the tabletop 2. The rotating cooperation between the rotating shaft 32 and the tabletop 2 can be achieved by shaft hole cooperation, or by cooperation with bearings, but is not limited thereto. The locking piece 42 is a component for locking the swing lever 41, for example, a bolt or a latch. In this way, the swing lever 41 is swung to drive the rotating shaft 32 and then the limiting plate 31, and after the angle is determined, the swing lever 41 is locked by the locking piece 42 to lock the position of the limiting plate 31.

[0025] In some embodiments, an arc slot 43 is formed at the bottom of the tabletop 2 with the rotating shaft 32 as the center; the locking piece 42 comprises a screw rod 421 which is rotatably connected to the swing lever 41, and the top of the screw rod 421 is provided with a clamping head 422 which is embedded in the arc slot 43; a locking ring 423 is threadedly installed on the screw rod 421, and the screw rod 421 is locked by rotating the locking ring 423 upward. It can be understood that the clamping head 422 can slide in the arc slot 43, or can be limited by each other, for example, both the sliding slot and the clamping head 422 are arranged in a T-shaped structure. In this way, the clamping head 422 is locked by rotating the locking ring 423 upward, and then the screw rod 421 and the swing lever 41 are locked. Further, a gasket 424 is arranged between the locking ring 423 and the bottom of the tabletop 2. The gasket 424 is a component for evenly distributing the force of the locking ring 423 acting on the bottom of the tabletop 2, for example, a steel sheet, an iron sheet, or a non-slip material such as plastic or rubber, but is not limited thereto.

[0026] In some embodiments, referring to Figure 4 The bottom of the tabletop 2 is arranged with positioning holes 44 in an arc shape and at intervals with the rotating shaft 32 as the center, and the locking piece 42 is a positioning shaft 45 which is movably installed on the swing lever 41 and can be inserted into the positioning hole 44. Here, the positioning shaft 45 and the swing lever 41 can be threadedly connected, and the positioning shaft 45 is inserted into the positioning hole 44 by rotating the positioning shaft 45. Of course, the positioning shaft 45 and the swing lever 41 can also be cooperated by sliding shaft hole, and the positioning shaft 45 and the positioning hole 44 are threadedly connected, so that the positioning shaft 45 and the positioning hole 44 can also be cooperated.

[0027] In some embodiments, referring to Figures 1-2 The two side edges of the tabletop 2 close to the blocking structure 3 are at an angle greater than 90 degrees. Since the tabletop 2 in the prior art is a square structure, the angle of the inclined side is 90 degrees. When the angle of the limiting plate 31 is greater than 90 degrees, the area of the tabletop 2 is not enough, so the angle of the side edge of the tabletop 2 is expanded to correspond to the adjustable limiting plate 31.

[0028] The above merely describes a preferred embodiment of the present application; the scope of protection of the present application is not limited thereto. Any skilled person in the art, according to the technical scheme and improvement concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the scope of protection of the present application.
