Description

Technical Field

[0001] The invention belongs to the technical field of battery production, and particularly relates to a pole post shaping device for a lead-acid battery. Background Art

[0002] A storage battery includes a housing and a plate group inside the housing. The plate group needs to go through a casting and welding operation to form a lead channel for conducting current and positive and negative pole posts. During the production and manufacturing process of the storage battery, after the casting and welding of the storage battery are completed, the pole posts of the storage battery are often skewed due to handling and transfer, which affects the subsequent assembly of the sealing ring and the cover.

[0003] For example, Chinese invention CN111162238B discloses a lead-acid battery end pole post shaping device, which shapes the end pole post of the lead-acid battery through a shaping mechanism. Four shaping push plates push the end pole post from four different directions, so that the position of the end pole post on the lead-acid battery does not shift.

[0004] However, in the above technical solution, multiple cylinders need to act to shape the pole post, making the overall structure relatively complex, prone to position errors, resulting in reduced positioning accuracy and affecting the overall pole post shaping effect. Summary of the Invention

[0005] The purpose of the invention is to provide a pole post shaping device for a lead-acid battery, which synchronously drives the shaping claws to rotate through an internal gear ring, and uses the shaping claws to move the battery pole post to a position concentric with the shaping hole, so as to realize the shaping of the battery pole post, and solves the problems of low shaping positioning accuracy and poor shaping effect of the existing battery pole post.

[0006] To solve the above technical problems, the invention is realized through the following technical solutions:

[0011] As a preferred technical solution of the present invention, the levers connecting the two inner gear rings are connected by a connecting rod; the telescopic end of the driving device is hinged to the connecting rod, so that one driving device drives the two inner gear rings to rotate synchronously.

[0012] As a preferred technical solution of the present invention, a circular ring plate arranged concentrically with the shaping hole is fixedly connected to the upper surface of the fixing plate; the outer wall of the inner gear ring is rotatably connected to the inner wall of the circular ring plate.

[0013] As a preferred technical solution of the present invention, the shaping claw can be rotated to be completely located between the outer edge of the shaping hole and the inner gear ring when the shaping operation is not being performed.

[0016] The present invention has the following beneficial effects:

[0017] 1.

[0018] 2. The present invention realizes synchronous shaping and positioning of the battery pole in all directions through the synchronous rotation of multiple shaping claws, thereby effectively improving the shaping efficiency of the battery pole and ensuring the overall production efficiency.

[0030] Embodiment 1

[0031] Please refer to Figures 1 to 3As shown in the figure, the present invention is a pole shaping device for a lead-acid battery, including a conveyor, a lifting mechanism, and a shaping mechanism. The conveyor is used to convey the battery, and the lifting mechanism is used to lift the battery to the position of the shaping mechanism.

[0032] The shaping mechanism includes a fixing plate 1, which is fixedly installed through a support rod. The fixing plate 1 is provided with two shaping holes 101. The positions of the two shaping holes 101 are adapted to the positions of the two poles on the battery. And several shaping claws 2 and two internal gear rings 3 are rotatably connected to the upper surface of the fixing plate 1. The internal gear rings 3 are concentrically arranged with the shaping holes 101. Among them, a circular ring plate 102 concentrically arranged with the shaping holes 101 is welded or bolted to the upper surface of the fixing plate 1. The outer wall of the internal gear ring 3 is rotatably connected to the inner wall of the circular ring plate 102 through a bearing, so as to realize the rotational connection between the internal gear ring 3 and the fixing plate 1.

[0033] A driving device 4 is connected to the upper surface of the fixing plate 1 for driving the internal gear ring 3 to rotate through the driving device 4.

[0034] Several shaping claws 2 are arranged in a circumferential array along the shaping holes 101 and are stacked on each other in sequence. Specifically, each group of shaping claws 2 can be six or eight or more, such as six shown in the figure. The six shaping claws 2 are rotatably connected to the fixing plate 1 through a rotating shaft and are arranged in a circumferential array along the shaping holes 101, so that the shape formed after the shaping holes 101 rotate synchronously into the shaping holes 101 is a regular polygon and is concentric with the shaping holes 101.

[0035] As Figure 4 shown, one end of the shaping claw 2 is connected with a gear 201, and the gears 201 of the six shaping claws 2 in each group are all meshed with the internal gear ring 3 for synchronously driving the six shaping claws 2 to rotate through the internal gear ring 3, and using the six shaping claws 2 to dial the battery poles to the concentric position with the shaping holes 101 to realize the shaping of the battery poles.

[0036] Among them, the gear 201 is an incomplete gear, and the gear 201 and the shaping claw 2 are of an integral structure. And the shaping claw 2 is in a hooked shape structure, and the side surface is a curved surface structure, and the curved surface structure can avoid the situation of pinching the battery poles.

[0037] During shaping, the lifting mechanism lifts the battery from bottom to top, so that the two poles of the battery are respectively inserted into the two shaping holes 101. At this time, the driving device 4 is used to drive the internal gear ring 3 to rotate, and the internal gear ring 3 is used to synchronously drive the shaping claws 2 to rotate, so that the end of the shaping claws 2 rotates into the shaping holes 101, and thus the battery poles are dialed towards the center of the shaping holes 101 through the shaping claws 2.

[0038] When the six shaping claws 2 gradually rotate and clamp the battery pole, the battery pole and the shaping hole 101 are in a concentric position, thereby completing the shaping of the battery pole. The synchronous rotation of the shaping claws 2 makes the overall positioning accuracy better, which is conducive to improving the overall shaping effect.

[0039] Moreover, by synchronously rotating the multiple shaping fingers 2, the battery poles can be shaped and positioned synchronously in all directions at the same time, thereby effectively improving the shaping efficiency of the battery poles and ensuring the overall production efficiency.

[0040] At the same time, if Figure 5 As shown in the figure, the shaping claw 2 can be rotated to be completely located between the outer edge of the shaping hole 101 and the inner gear ring 3 when the shaping operation is not being performed, so as to avoid the situation where the battery pole position is greatly offset and is blocked by the shaping claw 2 when inserted into the shaping hole 101, thereby improving the overall reliability of use. In addition, the length of the shaping claw 2 is greater than the radius of the shaping hole 101, so that after the battery pole is inserted into the shaping hole 101, it can be accurately moved by the shaping claw 2, thereby avoiding the situation where the shaping claw 2 is too short, the battery pole position is greatly offset, and cannot be moved by the shaping claw 2, thereby effectively improving the overall reliability and stability of use.

[0041] Example 2

[0042] Based on the first embodiment, the inner gear ring 3 is fixedly connected to a lever 301 arranged radially, and the lever 301 and the inner gear ring 3 are connected by screws or welding. The driving device is a cylinder, a hydraulic cylinder or an electric push rod; one end of the driving device is hinged to the fixed plate 1, and the other end is hinged to the lever 301, so that the inner gear ring 3 is driven to rotate through the telescopic action of the telescopic end of the driving device.

[0043] In addition, the lever 301 connected to the two inner gear rings 3 is hingedly connected through a connecting rod 302; the telescopic end of the driving device is hingedly connected to the connecting rod 302, so that the two inner gear rings 3 can be driven to rotate synchronously through a driving device, which is beneficial to reducing the cost of components. At the same time, the two inner gear rings 3 are packaged to rotate synchronously, so that the shaping claws 2 in the two inner gear rings 3 rotate at the same angle, which is beneficial to improve the overall shaping accuracy and make the position accuracy of the two battery poles after shaping higher.

[0044] At the same time, the driving device 4 can also be a motor, and is connected to the fixed plate 1 through a motor frame. The motor is connected to a driving gear meshing with the inner gear ring 3, and is used to drive the inner gear ring 3 to rotate through the driving gear.

[0045] ​​Or, two rotating shafts are rotationally connected through a bearing bracket. One end of each rotating shaft is connected to a driving wheel meshing with the internal gear ring 3, and the other end is connected to a transmission wheel. The motor drives the two rotating shafts to rotate simultaneously through a chain or a belt, so as to synchronously drive the two internal gear rings 3 to rotate, and the shaping operation of the battery pole column is also realized.
