Description

Technical Field

[0001] This utility model relates to the field of anode plate pickling technology, specifically to an anode plate pickling fixture. Background Technology

[0002] The anode plate undergoes a redox reaction to form copper foil on its surface, which is used to produce copper foil for lithium batteries. Before the redox reaction, the anode plate needs to be acid-washed to ensure its surface cleanliness.

[0003] During the pickling process, the anode plate is placed in the anode plate pickling fixture. The hook lifts the anode plate pickling fixture into the "pickling tank", "pure water tank", "ultrasonic tank (vibration cleaning)" and "pure water tank (hot water)" in sequence to clean the anode plate.

[0004] The anode plate pickling fixture is cage-like, with vertical and longitudinal bars forming a grid. The anode plate is placed by inserting it into the corresponding grid. However, in existing anode plate pickling fixtures, the vertical and longitudinal bars are fixed, resulting in a fixed grid size. When the anode plate is smaller than the grid size, multiple anode plates can only be stacked on top of each other within that grid. The overlapping areas are not adequately cleaned by the acid solution, thus affecting the pickling effect. Utility Model Content

[0005] The purpose of this invention is to provide an anode plate pickling fixture that can adjust the grid size according to the size of the anode plate so that the anode plates are placed as separately as possible to avoid stacking, thereby improving the pickling effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pickling fixture for an anode plate includes several central square tubes and two rows of vertical corner strips. The central square tubes have several rectangular elongated holes on both sides of their transverse sides. The vertical corner strips have several supporting notches on their transverse sections, each supporting notch having a connecting hole on its upper side. Several transverse strips connect the central square tubes and the vertical corner strips. The inner end of each transverse strip has a protrusion, and the bottom side of the protrusion has an insertion groove. The rectangular elongated holes allow the protrusion to be inserted, and the insertion groove can engage with the bottom edge of the rectangular elongated hole. The outer end of each transverse strip has a protrusion with a bent strip on its bottom edge. The protrusion has a connecting hole, and the bent strip can engage with the supporting notch. The protrusion and the vertical corner strips are connected by bolts. Two adjacent middle square tubes are connected by connecting corner strips along the longitudinal direction. The front and back sides of the middle square tubes are provided with figure-9 shaped through holes, through which the connecting corner strips can pass. The bottom edge of the vertical piece of the connecting corner strip is provided with several slots, which can be inserted into the strip-shaped opening of the figure-9 shaped through hole. Two adjacent vertical corner strips are connected by longitudinal corner strips. There is an insertion gap between the outer end of the horizontal strip and the horizontal piece of the vertical corner strip. Each insertion gap allows the vertical piece of the longitudinal corner strip to be inserted. The bottom edge of the vertical piece of the longitudinal corner strip is provided with several insertion notches, which can be engaged with the upper edge of the protrusion. When the insertion notch is engaged with the upper edge of the protrusion, the horizontal piece of the longitudinal corner strip abuts against the top edge of each horizontal strip.

[0008] Specifically, six rectangular elongated holes are provided on both sides of the central square tube, and the six rectangular elongated holes are evenly distributed vertically.

[0009] Specifically, the transverse sidewall of the central square tube has six figure-9 shaped perforations, which are evenly distributed vertically.

[0010] Specifically, the bottom edge of the vertical piece connecting the corner strip has five slots, which are evenly distributed along the longitudinal direction.

[0011] Specifically, the bottom edge of the vertical strip of the longitudinal corner bar is provided with five insertion notches, which are evenly distributed along the longitudinal direction.

[0012] Specifically, the top of each vertical corner strip on the front and rear sides and each middle square tube is connected to a horizontal frame strip by screws, and the horizontal frame strip has a lifting hole.

[0013] Specifically, the top of each vertical corner strip on both sides of the horizontal axis is connected to a longitudinal frame strip by screws.

[0014] Specifically, the central square tube, vertical corner strips, horizontal strips, connecting corner strips, longitudinal corner strips, horizontal frame strips, and longitudinal frame strips are all made of acid-resistant rubber.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] Depending on the required width of the anode plate to be pickled, assemble an appropriate number of longitudinal corner strips 5 and connecting corner strips 4, ensuring that the height between two adjacent layers of connecting corner strips 4 (and longitudinal corner strips 5) matches the width of the anode plate. For example, if the anode plate is large, it can be assembled as follows: Figure 1 The diagram shows a three-layer longitudinal corner strip structure 5; if the anode plate width is small, it can be assembled into a six-layer longitudinal corner strip structure 5 (not shown in the figure).

[0017] In this way, the distance between two adjacent vertical connecting corner strips 4 (and longitudinal corner strips 5) is adapted to the width of the anode plate, so that as many anode plates as possible can be placed individually in the grid formed by the two adjacent connecting corner strips 4 (and longitudinal corner strips 5), avoiding multiple anode plates being clustered together in the same grid and stacked on top of each other, which would affect the pickling effect.

[0018] For anode plates of different widths, this invention allows for quick assembly and disassembly to form a grid of a suitable size.

[0019] The front and rear sides of the central square tube 1 are provided with figure-9 shaped through holes 12, through which the connecting corner strip 4 can pass. The bottom edge of the vertical piece of the connecting corner strip 4 is provided with several slots 41, which can be inserted into the strip-shaped slits 121 of the figure-9 shaped through holes 12, so that the connecting corner strip 4 can be quickly assembled and disassembled.

[0020] The bottom edge of the vertical strip 5 has several insertion notches 51 (see...) Figure 3 The insertion notch 51 can be inserted into the upper edge of the protrusion 33. When the insertion notch 51 is inserted into the upper edge of the protrusion 33, the horizontal piece of the longitudinal corner strip 5 abuts against the top edge of each horizontal strip 3, so that the longitudinal corner strip 5 can be quickly disassembled and assembled.

[0021] In addition, several horizontal bars 3 connect the central square tube 1 and the vertical corner strip 2. The inner end of the horizontal bar 3 is provided with a protrusion 31, and the bottom side of the protrusion 31 is provided with a insertion groove 32. The square elongated hole 11 allows the protrusion 31 to be inserted, and the insertion groove 32 can form a snap-fit ​​with the bottom edge of the square elongated hole 11 (see reference). Figure 2 , Figure 3 This ensures the overall structure of the pickling fixture is stable and reliable. Attached Figure Description

When the insertion notch 51 is inserted into the upper edge of the protrusion 33, the horizontal piece of the longitudinal corner strip 5 abuts against the top edge of each horizontal strip 3, so that the longitudinal corner strip 5 can be quickly disassembled and assembled.

[0055] In addition, several horizontal bars 3 connect the central square tube 1 and the vertical corner strip 2. The inner end of the horizontal bar 3 is provided with a protrusion 31, and the bottom side of the protrusion 31 is provided with a insertion groove 32.
