Description

Technical Field

[0001] The utility model relates to an automatic correction mechanism for a battery pole, belonging to the technical field of battery manufacturing. Background Art

[0002] During the manufacturing process of batteries, their poles are usually easily deflected during transportation, which affects the assembly of terminals, welding terminals and caps in subsequent processes. Therefore, it is necessary to use a shaping mechanism to shape the poles to keep them upright to facilitate subsequent assembly and processing. There are usually two types of automatic correction methods for battery poles at present. One is a step-by-step method that first lifts the pole up and then corrects it from the side; the other is a one-step method that sets multiple clamping structures along the radial direction of the pole to clamp the pole from multiple directions.

[0003] For example, the utility model patent with application number CN202022799084.3 and the name of "A pole correction machine", its shaping device includes a prying assembly, a lateral correction assembly and a longitudinal correction assembly which are arranged in sequence along the moving direction of the conveyor belt assembly and respectively installed on the mobile frame. Another example is the invention application with application number CN202311470210.2 and the name of "A battery pole shaping device", in which a pair of clamping and positioning mechanisms are installed side by side on the battery conveying mechanism, a lifting mechanism is vertically installed on the side of one clamping and positioning mechanism away from the other clamping and positioning mechanism, a first shifting mechanism is horizontally installed on the lifting mechanism, and a first correction member is installed on the first shifting mechanism; a lifting mechanism is vertically installed between the two clamping and positioning mechanisms, a second shifting mechanism is horizontally installed on the lifting mechanism, and a second correction member is installed on the second shifting mechanism. In the above correction method, the correction steps need to be divided into two or even three times, which is very inefficient.

[0004] For example, in the invention application with application number CN202211649519.3 and titled “A pole shaping device for lead-acid batteries”, shaping claws are arranged along a circular array of shaping holes, and the shaping claws are synchronously driven to rotate by an inner gear ring, so that the shaping claws move the battery pole to a position concentric with the shaping hole, thereby achieving the shaping of the battery pole. Another example is the invention application with application number CN202211649519.3 and titled “A pole shaping device for lead-acid batteries”, in which the shaping mechanism includes a fixed plate, which is provided with two shaping holes and is rotatably connected to a number of shaping claws and two inner gear rings; the fixed plate is connected to a driving device for driving the inner gear ring to rotate; a number of shaping claws are arranged in an array along the circumference of the shaping hole and are stacked one on top of another; a gear is connected to one end of the shaping claw, and the gears of a number of shaping claws are all meshed with the inner gear ring, which is used to synchronously drive a number of shaping claws to rotate through the inner gear ring, and use a number of shaping claws to move the battery pole to a position concentric with the shaping hole, thereby realizing the shaping of the battery pole. However, in the above structure, a driving force directly drives a number of shaping claws arranged along the circumference to move at the same time, which has high assembly requirements and a complex structure. Utility Model Content

[0005] The utility model aims at the above-mentioned problems occurring in the current battery pole correction operation, and proposes an automatic battery pole correction mechanism, which utilizes a power component to drive a clamping head to perform linear motion to push the pole from one direction, and drives other clamping heads to push the pole from other directions, so as to achieve the correction effect at one time.

[0006] The technical means adopted by the utility model to solve the above problems are: an automatic correction mechanism for battery poles, including a bracket and a power component and a clamping component arranged on the bracket, wherein the clamping component includes more than two clamping heads arranged on the periphery of the pole, and the clamping heads are divided into a main clamping head and a slave clamping head, the main clamping head is connected to the movable end of the power component and moves linearly under the drive of the power component to approach or move away from the pole from the side, and the slave clamping head is pushed by the main clamping head and then rotated to approach or move away from the pole from the side. When more than two clamping heads approach the pole from different directions, the deflected pole can be pushed to the correct position to achieve the correction effect.

[0007] Furthermore, the main clamping head is slidably connected to the bracket, the slave clamping head is rotatably connected to the bracket, and one surface of the slave clamping head is in contact with one side surface of the main clamping head, so that the main clamping head can drive the slave clamping head to rotate when it moves linearly.

[0008] Further, the surface of the slave clamping head at one end away from the pole is in wedge contact with the side surface of the main clamping head, so that the main clamping head can push the slave clamping head to rotate from the side surface when the main clamping head moves linearly.

[0009] Furthermore, the slave clamping heads include two, which are respectively arranged on both sides of the main clamping head. When the power component drives the main clamping head to move linearly, the three clamping heads squeeze and push the pole from three different directions respectively to achieve the correction effect.

[0010] Furthermore, the main clamping head is in a V-shaped structure, the tip of the V-shape is close to the pole, and both sides of the V-shape are in contact with a slave clamping head respectively.

[0011] Further, a guide post is provided at the position where the slave clamping head contacts the main clamping head. The slave clamping head can be pushed and rotated by the main clamping head through the matching contact between the guide post and the side wall of the main clamping head.

[0012] Further, the guide post is rotatably arranged on the slave clamping head through a center pin. When the master clamping head pushes the slave clamping head to rotate, the guide post also rotates, reducing the friction between the guide post and the master clamping head.

[0013] Furthermore, the automatic correction mechanism also includes a movable component, and the bracket is connected to the movable end of the movable component and is driven by the movable component to move vertically toward or away from the pole along the battery.

[0014] Furthermore, the automatic correction mechanism also includes a pressure plate component arranged on the bracket, and a comb-shaped pressure head is provided at the bottom end of the pressure plate component.

[0015] Furthermore, the end surface of the pressing head close to the electrode plate group exceeds the end surface of the clamping head close to the electrode plate group.

[0016] The beneficial effects of the utility model are:

[0017] 1. The utility model only connects the main clamping head with the power component and performs linear motion under the drive of the power component. The motion mode is simple and easy to implement. The slave clamping head rotates in coordination with the main clamping head to avoid direct contact between the slave clamping head and the power component, making the structure simpler, more coordinated and easier to maintain.

[0018] 2. The utility model makes wedge-shaped contact between the main clamping head and the slave clamping head, so that the main clamping head can drive the slave clamping head to rotate when the power component drives the main clamping head to move linearly, thereby achieving the effect of correcting the pole.

[0019] 3. The utility model provides a pressing component on the bracket, and presses the pole plate into place while correcting the pole, so that two sets of operations are completed at the same time, which simplifies the operating equipment and improves the efficiency.

DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings. The accompanying drawings are only used for exemplary descriptions, and are only schematic diagrams, not actual pictures, and cannot be understood as limiting the present patent; in order to better illustrate the embodiments of the utility model, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. Embodiment 1

[0030] A battery pole automatic correction mechanism, such as Figure 1 and Figure 2As shown, the frame 1 includes a movable part 5, which is provided on the frame 1. In this embodiment, the movable part 5 is a cylinder. The movable end of the movable part 5 is connected to the bracket 2, and a guide column 11 and a guide sleeve 12 are provided between the frame 1 and the bracket 2 as a guide for movement. The bracket 2 reciprocates up and down under the drive of the movable part 5 to approach or move away from the battery 100 below.

[0031] like Figure 2 and Figure 3 As shown, a support plate 25 is provided near the lower part of the bracket 2, a power component 4 is provided on the upper surface of the support plate 25, and a clamping component 3 is provided on the lower surface. In this embodiment, the power component 4 is also a cylinder. Figure 6 As shown, the movable end of the power component 4 is connected to a vertical plate 23 perpendicular to the support plate 25, the other end of the vertical plate 23 is connected to a connecting plate 24 arranged parallel to the support plate 25, the other end of the connecting plate 24 is connected to a main clamping head 31, and the upper surface of the connecting plate 24 is connected to the lower surface of the support plate 25 through a guide rail 22. In this way, the power component 4 and the main clamping head 31 are respectively arranged on the upper and lower surfaces of the support plate 25 through the vertical plate 23 and the connecting plate 24, and the power component 4 drives the main clamping head 31 to reciprocate horizontally when it is in motion.

[0032] like Figure 4 and Figure 5 As shown, in this embodiment, the clamping component 3 includes a main clamping head 31 and two slave clamping heads 32. The main clamping head 31 is V-shaped as a whole, and its V-shaped tip portion faces the position of the pole 102, and the V-shaped large end is connected to the connecting plate 24. The two slave clamping heads 32 are respectively arranged on both sides of the V-shape of the main clamping head 31, and one main clamping head 31 and two slave clamping heads 32 are arranged circumferentially along the pole 102. The slave clamping head 32 is arranged on the support plate 25 through the connecting shaft 21, so that the slave clamping head 32 can rotate relative to the support plate 25 with the connecting shaft 21 as the center. A guide column 33 is provided on the side of the end of the slave clamping head 32 away from the pole 102 close to the main clamping head 31, and the guide column 33 is connected to the slave clamping head 32 through a center pin 34. Preferably, the guide column 33 can rotate relative to the slave clamping head 32 with the center pin 34 as the center. Therefore, when the power component 4 drives the main clamping head 31 to move toward the pole 102 through the vertical plate 23 and the connecting plate 24, the two sides of the V-shaped main clamping head 31 squeeze and push the two slave clamping heads 32 respectively, pushing the slave clamping heads 32 to rotate, and the ends of the two slave clamping heads 32 away from the pole 102 move away from each other, while the ends close to the pole 102 move closer to each other and squeeze and push the pole 102 together with the tip of the main clamping head 31 to calibrate. Preferably, the ends of the two slave clamping heads 32 close to the pole 102 protrude toward the side of the pole 102 respectively, and when calibrating the pole 102, as shown in FIG. Figure 5As shown, a main clamping head 31 and two sub-clamping heads 32 push the pole 102 from three different directions, and the angles formed between any two adjacent clamping heads and the pole 102 are similar, preferably about 120 degrees.

[0033] In this embodiment, two sets of the clamping components 3 are provided to calibrate two poles 102 of a battery 100 at the same time. Embodiment 2

[0034] In this embodiment, Figure 7 and Figure 8 As shown, the support 2 is also provided with a pressure plate component 6, which includes an intermediate plate 62 and a pressure head 61. The pressure head 61 is connected to the support 2 through the intermediate plate 62, and the number of the pressure heads 61 is equal to the number of the plate groups 101 of a battery 100. The plurality of pressure heads 61 are combined into a comb shape so that one pressure head 61 can penetrate into the upper part of one plate group 101. Fig. 9 As shown, the pressure head 61 is arranged at a position close to the front and lower part of the clamping head, so that when working, the pressure head 61 can avoid the position of the pole 102 and fall into the upper surface of the pole group 101. When the movable component 5 drives the bracket 2 downward, the pressure head 61 is pressed down synchronously to squeeze the protective sheet above the pole group 101 into place. At the same time, the power component 4 drives the clamping head to correct the pole into place, completing the operation of pressing the protective sheet and correcting the column head in one step. In the previous operation, a special pressing mechanism is required to press the protective sheet into place. In this embodiment, the same work can be completed by only a simple pressing plate component, which not only reduces the equipment cost but also increases the production speed. Of course, the number and position of the pressure heads can be selected according to different battery specifications to meet different requirements.

[0035] The above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Technicians in the relevant technical field may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the protection scope of the present invention, and the protection scope of the present invention should be defined by the claims.
