Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology, specifically relating to a battery electrode compaction device. Background Technology

[0002] Chinese Patent (Announcement No.: CN217589338U, Announcement Date: October 14, 2022) discloses a battery electrode compaction device. This device securely clamps the battery and applies a uniform pushing force to the electrode group, enabling the electrode group to quickly and stably reach the bottom of the tank cavity. However, this device applies downward pressure to the busbars of the electrode group to ensure it is fully seated at the bottom of the tank. During this downward pressing process, the electrode group's lugs are easily bent and damaged, leading to premature battery lifespan. Therefore, existing battery electrode compaction devices need to be upgraded to ensure the electrode group is firmly seated at the bottom of the tank without damaging the electrode group or causing the lugs to bend. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery electrode group compaction device. The device solves the problem of electrode group plate ear deformation and bending by using an elastic electrode group pressure rod design, thereby improving the reliability of assembly quality.

[0004] The technical solution of this utility model is as follows: Above the horizontal plate is a cylinder for driving the horizontal plate to rise and fall vertically, and a guide rod for guiding the horizontal plate to rise and fall. The upper end of the guide rod is mounted on a fixed plate A via a linear bearing. The cylinder barrel is fixed to the horizontal plate, and the piston rod of the cylinder is fixed to the fixed plate A. At each end below the horizontal plate is a vertical plate, with a sliding groove at the bottom of the vertical plate. Below the horizontal plate is a horizontally arranged movable plate, which is screwed onto the sliding groove at the bottom of the vertical plate. A horizontally arranged sliding groove is opened in the middle of the movable plate, and multiple elastic pole pressure rods are vertically arranged at the sliding groove on each movable plate. Each elastic pole pressure rod includes a long screw, a spring, and a pressing block. The upper part of the long screw is fitted with a spring, and an adjustment hole is provided near the lower end of the spring on the long screw. The pressing block is movably mounted at the adjustment hole of the long screw via a fixing screw. When the spring is in its naturally extended state, the lower end of the spring contacts the upper end of the pressing block.

[0005] The upper side of the pressing block has a fixing hole corresponding to the adjustment hole, and the fixing screw passes through the fixing hole and the adjustment hole.

[0006] The upper part of the pressing block is detachably connected to a sleeve, and the upper side of the sleeve is provided with a fixing hole, and the lower end of the spring contacts the upper end of the sleeve.

[0007] A guide rod is provided on each of the left and right sides above the horizontal plate, and a cylinder is provided between the two guide rods.

[0008] The upper end of the long screw is detachably and fixedly connected to the slide groove.

[0009] The long screw has a threaded section at its upper end. The fastening nut assembly for securing the long screw at the sliding groove of the movable plate includes nut one installed on the threaded section above the sliding groove and nut two installed on the threaded section below the sliding groove.

[0010] The nut is mounted on the slide groove by a slider; the slider has a slot below it that engages with the slide groove, and a clearance hole in the middle of the slider to accommodate the long screw.

[0011] The movable plate consists of two pieces, with a groove in the middle of each piece. Each movable plate has six elastic pressure rods at the groove.

[0012] The adjustment hole is an oblong hole.

[0013] The pressing block includes a pressure plate and a connecting screw connected to the middle of the pressure plate. The connecting screw is threadedly connected to the sleeve.

[0014] This invention upgrades and modifies the existing battery electrode group compaction device by pressing the electrode group pressure bar onto the bottom of the tank, thereby pressing the electrode group firmly without damaging the electrode group or causing the plate ears to bend, thus improving the battery assembly quality. At the same time, the position of the electrode group pressure bar is flexibly adjustable, improving the applicability of the device. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Figure 1 , 2 In this utility model, a battery electrode compaction device includes a horizontal plate 1, with a guide rod 2 on each side above the horizontal plate 1. A cylinder 3 is located between the two guide rods 2 to drive the entire compaction device to move vertically up and down. The upper ends of the guide rods 2 are mounted on a fixed plate A via linear bearings. The cylinder barrel of the cylinder 3 is fixed to the horizontal plate 1, and the piston rod of the cylinder 3 is fixed to the fixed plate A. The fixed plate A is fixedly installed.

[0021] A vertical plate 4 is provided at each of the two ends below the horizontal plate 1. The bottom of the vertical plate 4 is provided with a sliding groove. Two movable plates 5 are provided below the horizontal plate 1. The movable plates 5 are installed on the sliding groove at the bottom of the vertical plate 4. They can be moved on the sliding groove to adjust their position. After the position is aligned, they are fixed with screws.

[0022] Two movable plates 5, each with a groove in the middle, and each movable plate 5 has a fastening nut assembly for six pole pressure rods at the groove. The fastening nut assembly includes a nut 6 at the threaded section above the groove and a nut 13 at the threaded section below the groove. Nut 6 is mounted on the groove via a slider 14. The slider 14 has a slot at its bottom that engages with the groove, and a clearance hole in its center for accommodating the long screw 7.

[0023] The pole group pressure rod is equipped with a long screw 7, which passes through the movable block 6 of the pole group pressure rod for fixed connection. A spring 8 is sleeved on the upper part of the long screw 7, and an adjustment hole is provided at the lower part of the long screw 7. A sleeve 9 is sleeved on the lower adjustment hole of the long screw 7. A fixing screw 10 passes through the sleeve 9 and through the adjustment hole of the long screw 7. The pressing block 11 is provided with a threaded thread, and the pressing block 11 is connected to the bottom end of the sleeve 9 through the threaded thread.

[0024] After the electrode group clamping fixture is correctly positioned, the operator places the electrode group into the battery compartment (at this point, the electrode group is not yet at the bottom of the compartment). In automatic operation mode, the battery is automatically fed into the compaction fixture. Cylinder 3 drives the entire compaction device downwards. During the descent, the electrode group compaction fixture presses down on the electrode group busbar, causing the electrode group to slowly press down until it is firmly placed at the bottom of the compartment.

[0025] Before the electrode group pressure rod presses down, the spring is in a relaxed state (i.e., naturally extended state). The fixing screw 10 is at the bottom of the adjustment hole. When the pressing block 11 presses down on the manifold, it drives the sleeve 9 to move slightly upward at the adjustment hole. At this time, the spring 8 is in a slightly compressed state. After the pressing block 11 presses down further until the electrode group is placed at the bottom of the tank, the pressing block 11 is supported by the bottom electrode group and stops pressing down. It pushes the sleeve 9 to continue moving upward at the adjustment hole. At this time, the spring 8 is in a compressed state, which can effectively prevent the pressing block 11 from continuing to exert pressure on the manifold and solve the problem of plate ear deformation and bending.

[0026] After the pressing action is completed, cylinder 3 drives the entire compaction device to rise, and the battery is transported to the next process.

[0027] This design ensures that the electrode group is pressed down to the bottom of the groove, while also preventing the electrode group from being excessively pressed down to the point that the plate ears bend and deform, thus improving the reliability of the assembly quality.

[0028] The above describes one embodiment of the present invention in detail. However, the present invention is not limited to the described embodiment. Those skilled in the art can make other equivalent modifications or substitutions without departing from the spirit of the present invention. These equivalent modifications or substitutions are included within the scope defined by the claims of this application.
