Description

Technical Field

[0001] The invention relates to a technology in the field of energy storage batteries, in particular to a solid electrolyte clamping and rotating fixture. Background Art

[0002] The solid electrolyte surface spraying equipment currently on the market is too simple. For example, the fixture for clamping the rotating solid electrolyte is clamped by a cylinder or a single-sided positioning clamping mechanism, which cannot be quickly replaced for products of different models and sizes. The product positioning and centering accuracy is also not high, and there is a problem of uneven spraying of the conductor, which cannot meet the requirements of solid electrolytes for surface spraying quality. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a solid electrolyte clamping rotating fixture, which has high solid electrolyte positioning and centering accuracy and can improve the surface spraying quality of the solid electrolyte.

[0004] The present invention is achieved through the following technical solutions:

[0005] The invention comprises: a spring seat, a guard plate, a positioning shaft, a clamping push block, a mounting plate and a base;

[0006] The bottom of the mounting plate is rotatably connected to the base via a ball bearing structure, and the positioning shaft is arranged at the center of the mounting plate;

[0007] There are no less than two spring seats fixed on the mounting plate and evenly arranged around the positioning shaft; the spring seats are fixed with clamping springs; and the intervals between the spring seats are arranged with clamping push blocks;

[0008] There are no less than two guard plates, which are evenly distributed around the positioning shaft. The internal contour of the guard plates matches the shape of the solid electrolyte and wraps the parts of the solid electrolyte that do not need to be sprayed. The guard plates are fixed with protrusions through positioning pins, and each protrusion is fixedly connected to the clamping spring; two adjacent protrusions are hinged to the clamping push block through a hinge plate; the clamping push block is movably arranged on the mounting plate, and synchronously moves to control the closing or separation of the guard plates.

[0009] Preferably, there are two guard plates; the same clamping and pushing block is hinged to the protrusions of the two guard plates respectively through hinge plates, and the two clamping and pushing blocks synchronously control the closing or separation of the guard plates.

[0010] Preferably, each of the clamping and pushing blocks is respectively arranged on a corresponding linear displacement mechanism.

[0011] Preferably, the protrusions are respectively arranged on corresponding linear displacement mechanisms.

[0012] The bottom of the mounting plate is convex in the axial direction of the positioning shaft and is cylindrical, and a concave annular groove is arranged on the outer circumference.

[0013] Technical Effects

[0014] Compared with the prior art, the present invention has the following technical effects:

[0015] 1) The spring pushes the guard plate to complete the clamping and the solid electrolyte and the positioning axis are relatively stationary, so that the positioning and clamping of the solid electrolyte are stable and reliable, ensuring the reliability of the surface spraying quality of the solid electrolyte;

[0016] 2) The center positioning method is adopted to ensure that the center axis position of the same batch of products is consistent, and the concentricity can reach 0.1mm;

[0017] 3) When producing different types of solid electrolytes, only the protective plate needs to be replaced, which improves the efficiency of the changeover work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, this embodiment relates to a solid electrolyte clamping rotating fixture 1, comprising: a pair of spring seats 11, a pair of guard plates 12, a positioning shaft 13, a pair of clamping push blocks 14, a mounting plate 15, a hinge plate 16 and a base 18;

[0026] The mounting plate 15 is a cross structure, the bottom is rotatably connected to the base 18 via a ball bearing structure, and a positioning shaft 13 is provided at the center of the mounting plate 15;

[0027] The pair of spring seats 11 are both fixed with a clamping spring 17, and the other end of the clamping spring 17 is fixedly connected to the protrusion 19;

[0028] The protrusion 19 is connected to the guard plate 12 through a positioning pin, and the two protrusions 19 are hinged to a pair of clamping and pushing blocks 14 through a hinge plate 16. The clamping and pushing blocks 14 are movably arranged on the mounting plate 15. The two clamping and pushing blocks 14 move synchronously to control the closing or separation of the guard plate 12.

[0029] The pair of guard plates 12 are symmetrically arranged around the positioning shaft 13, and the inner contour of the guard plate 12 matches the outer shape of the solid electrolyte 2 and wraps the part of the solid electrolyte 2 that does not need to be sprayed; for solid electrolytes of different models and spraying requirements, only the guard plate 12 needs to be replaced, such as Figure 3 shown.

[0030] The two clamping and pushing blocks 14 are respectively arranged on the linear displacement mechanisms, and the two linear displacement mechanisms are symmetrical with respect to the positioning shaft 13 .

[0031] The two protrusions 19 are respectively arranged on the linear displacement mechanisms, and the two linear displacement mechanisms are symmetrical with respect to the positioning shaft 13 .

[0032] The bottom of the mounting plate 15 is convex in the axial direction of the positioning shaft and is cylindrical, and a concave annular groove is provided on the outer circumference.

[0033] In this embodiment, an external clamping cylinder pushes a pair of clamping push blocks 14, and a pair of guard plates 12 are linked to open and close the clamp through a hinge plate 16. After the solid electrolyte 2 is placed on or taken out of the positioning shaft 13, the external clamping cylinder is reset, and the guard plates 12 are closed under the tension of the closing spring 17; Figure 4 As shown, the base 18 is fixed on the accessory shaft of the jig transmission assembly 4. As the jig transmission assembly 4 performs stepping motion, the O-belt on the rotary drive assembly 3 abuts against the concave annular groove at the bottom of the mounting plate 15, and uniform rotation is achieved through friction transmission, thereby spraying the conductive powder on the surface of the solid electrolyte.

[0034] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
