Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery production technology, and in particular to a dustproof clamping mechanism for lead-acid battery electrode groups. Background Technology

[0002] In lead-acid battery production, the pre-loading of electrode clusters is a core process, where electrode clusters are formed by clamping the electrode plates and AGM separators. Electrode clusters consist of alternating layers of positive and negative electrode plates and AGM separators, with the surfaces of the positive and negative plates containing active materials such as lead and lead dioxide. During the actual production process, friction and vibration during electrode plate handling, stacking, and pre-loading can easily cause dust to detach, forming lead-containing dust. Lead-containing dust is toxic; long-term inhalation or intake can lead to occupational chronic lead poisoning, seriously endangering employee health. Simultaneously, lead-containing dust is conductive; excessive lead-containing dust adhering to the electrode clusters can cause micro-short circuits within the battery or even render the battery unusable. Furthermore, lead-containing dust can clog separator pores, reducing battery capacity and lifespan. In addition, dust contamination can adhere to equipment and work surfaces, increasing the difficulty of foreign object control and affecting product consistency.

[0003] Traditional clamping mechanisms are mostly fixed clamping mechanisms, which only consider the clamping stability of the electrode group when fixing it, resulting in the powder on the edge of the electrode plate being more likely to fall off and scatter. In the electrode group pre-sinking process, removing the lead-containing dust attached to the clamp and electrode group is of great significance for improving battery quality and improving the working environment.

The first lead screw is drivenly connected to the first clamping part, and the second lead screw is drivenly connected to the second clamping part.

[0008] According to some embodiments of the present invention, the first drive motor / the second drive motor are respectively connected by a flexible coupling and the first lead screw / the second lead screw.

[0009] According to some embodiments of the present invention, the first lead screw / the second lead screw is connected to the first clamping part / the second clamping part respectively via a lead screw nut.

[0010] According to some embodiments of the present invention, the drive assembly is provided with at least two guide rods, and the at least two guide rods are respectively arranged on both sides of the axial direction of the first lead screw / second lead screw; the two guide rods are sequentially connected to the side plate and the partition plate.

[0011] According to some embodiments of the present invention, locking blocks are respectively provided on both sides of the upper part of the clamping block, and the locking blocks fix the upper part of the clamping block in the mounting groove of the fixing block by locking bolts.

[0012] According to some embodiments of the present invention, a contact block is provided on one side of the clamping block, the contact block is exposed on the outside of the fixing block, and the contact block abuts against the vibration element.

[0013] According to some embodiments of the present invention, the clamping plate has a fork-shaped structure and is provided with clearance slots.

[0014] According to some embodiments of this utility model, the vibration element is one or more of an eccentric vibrator, an electromagnetic vibrator, and a pneumatic vibrator.

[0015] A dustproof clamping mechanism for lead-acid battery electrode groups according to an embodiment of the present invention has at least the following beneficial effects: According to the present invention, vibration is applied to the clamping block by a vibration element to control the shedding of lead-containing dust adhering to the electrode group and the clamp, thereby reducing the amount of dust carried by the electrode group during pre-sinking.

Compared with a clamping plate without an inclined surface design, this structure can achieve a stronger end vibration effect under the same vibration element output, improving dust removal efficiency, while avoiding damage to the electrode group due to overall over-vibration.

[0018] According to the present invention, parallel vertical surfaces apply uniformly distributed pressure to both sides of the electrode group, avoiding the problem of excessive local pressure causing additional powder to fall off the electrode edges due to traditional fixing and clamping mechanisms. Stable distributed pressure also keeps the electrode group stacked neatly, reducing electrode misalignment or deformation caused by uneven clamping. Attached Figure Description

[0025] Reference Figures 1 to 5As shown, this utility model discloses a dustproof clamping mechanism for lead-acid battery terminals, including a clamping base 100 and a clamping unit 200. The clamping base 100 is provided with a driving assembly 150; the clamping unit 200 is provided with a first clamping part 201 and a second clamping part 202. The first clamping part 201 and the second clamping part 202 are slidably disposed on the clamping base 100 in a horizontal direction, and the first clamping part 201 and the second clamping part 202 can move closer to or further away from each other under the control of the driving assembly 150; the first clamping part 201 / the second clamping part 202... The two clamping parts 202 are respectively provided with a fixing block 210 and a clamping block 220; the fixing block 210 is connected to the drive assembly 150 for transmission, the fixing block 210 is provided with a mounting groove 211, and the upper part of the clamping block 220 is detachably disposed in the mounting groove 211; a vibration element 230 is provided on one side of the fixing block 210, and the working area of ​​the vibration element 230 abuts against the clamping block 220; a clamping plate 221 is provided at the lower end of the clamping block 220, one side of the clamping plate 221 is provided with a vertical surface 222, and the other side of the clamping plate 221 is provided with an inclined surface 223. Specifically, in this embodiment, the clamping base 100 provides an overall mounting base. The clamping base 100 is provided with a drive assembly 150. The clamping unit 200 is provided with a first clamping part 201 and a second clamping part 202. The first clamping part 201 and the second clamping part 202 are slidably disposed on the clamping base 100 in the horizontal direction. The first clamping part 201 and the second clamping part 202 can move closer to or further away from each other under the control of the drive assembly 150. The first clamping part 201 and the second clamping part 202 are respectively provided with a fixing block 210 and a clamping block 220. The fixing block 210 is connected to the drive assembly 150 via a transmission. The fixing block 210 is provided with a mounting groove 211. The upper part of the clamping block 220 is detachably mounted in the mounting groove 211 of the fixing block 210. The detachable mounting of the clamping block 220 in the mounting groove 211 of the fixing block 210 facilitates daily maintenance and replacement of clamping blocks 220 of different specifications, improving the versatility and maintainability of the equipment. A vibration element 230 is provided on one side of the fixing block 210. The working area of ​​the vibration element 230 abuts against the clamping block 220. A clamping plate 221 is provided at the lower end of the clamping block 220. A vertical surface 222 is provided on one side of the clamping plate 221, and an inclined surface 223 is provided on the other side of the clamping plate 221. When the drive assembly 150 controls the first clamping part 201 and the second clamping part 202 to approach each other, the vertical surface 222 of the clamping plate 221 of the first clamping part 201 and the vertical surface 222 of the clamping plate 221 of the second clamping part 202 approach each other, forming parallel vertical surfaces. This parallel vertical surface applies uniformly distributed pressure to both sides of the pole group, thereby fixing the pole group. The inclined surface 223 on one side of the clamping plate 221 is designed to reduce the cross-sectional area of ​​the clamping plate 221 in the vertical direction, so that the vibration energy is more efficiently concentrated at the end of the clamping plate 221.Compared to the clamping plate 221 without the bevel 223 design, this structure achieves a stronger end vibration effect under the same vibration element 230 output, improving dust removal efficiency while avoiding damage to the electrode group due to overall over-vibration. In the clamping state, the vibration element 230 is activated. The working area of ​​the vibration element 230 directly transmits vibration to the clamping block 220. Since the clamping block 220 and the clamping plate 221 are an integral structure, the vibration is further transmitted to the end of the clamping plate 221. The bevel 223 on one side of the clamping plate 221 reduces the cross-sectional area of ​​the clamping plate 221 in the vertical direction, allowing the vibration energy to be transmitted more concentratedly to the end of the clamping plate 221, thereby improving the vibration effect of the vibration element 230 on the end of the clamping plate 221. This promotes the shedding of lead-containing dust adhering to the electrode group surface and the clamp, achieving dust removal. The upper part of the clamping block 220 is detachably mounted in the mounting groove 211, facilitating the replacement of clamping blocks 220 of different sizes or shapes according to the electrode group specifications. This structure utilizes vibration element 230 to apply vibration to clamping block 220, controlling the shedding of lead-containing dust adhering to the electrode group and clamp, thereby reducing the amount of dust carried during electrode pre-sinking. This reduces the risk of internal micro-short circuits in the battery due to the conductivity of lead-containing dust and decreases the possibility of dust clogging the separator pores, thus improving battery capacity and lifespan.

[0026] In some embodiments of this utility model, the clamping base 100 is provided with a top plate 110, and side plates 120 are respectively provided on both sides of the top plate 110. Multiple partitions 130 are evenly distributed between the side plates 120 on both sides. A slot 111 is provided on the top plate 110, and the upper end of the partition 130 is inserted into the slot 111. The clamping unit 200 is disposed between two horizontally adjacent partitions 130. Specifically, in this embodiment, side plates 120 are respectively provided on both sides of the top plate 110. Multiple partitions 130 are evenly distributed between the side plates 120 on both sides. A slot 111 is provided on the top plate 110. The upper end of the partition 130 is inserted into the slot 111. Through this structural design, a plate-frame support structure is formed. The side plates 120 are used to define the installation range of the partitions 130 and provide overall rigidity. The slots 111 ensure accurate positioning of the upper ends of each partition 130, preventing the partitions 130 from shifting or tilting during use. The clamping unit 200 is disposed between two horizontally adjacent partitions 130. Each horizontally adjacent partition 130 constitutes a relatively independent pole group processing station. At the same time, the partitions 130 can provide support and improve the overall rigidity of the entire clamping base 100.

[0027] In some embodiments of this utility model, the drive assembly 150 includes a first drive motor 151, a second drive motor 152, a first lead screw 153, and a second lead screw 154. The first drive motor 151 and the second drive motor 152 are respectively fixedly disposed on both sides of the clamping base 100. The first lead screw 153 and the second lead screw 154 are respectively rotatably connected to the clamping base 100. The output end of the first drive motor 151 is driveably connected to the first lead screw 153, and the second drive motor 152 is driveably connected to the second lead screw 154. The first lead screw 153 is driveably connected to the first clamping part 201, and the second lead screw 154 is driveably connected to the second clamping part 202. Specifically, in this embodiment, the first drive motor 151 and the second drive motor 152 are respectively fixedly disposed on both sides of the clamping base 100. The first lead screw 153 and the second lead screw 154 are respectively rotatably connected to the clamping base 100. The output end of the first drive motor 151 is driveably connected to the first lead screw 153, and the second drive motor 152 is drively connected to the second lead screw 154. The first lead screw 153 is driven by the first clamping part 201, and the second lead screw 154 is driven by the second clamping part 202. The first drive motor 151 drives the first lead screw 153 to rotate, and the first lead screw 153 drives the first clamping part 201 to move horizontally. The second drive motor 152 drives the second lead screw 154 to rotate, and the second lead screw 154 drives the second clamping part 202 to move horizontally. By controlling the rotation direction and speed of the first drive motor 151 and the second drive motor 152, the first clamping part 201 and the second clamping part 202 can move closer to or further away from each other, thereby realizing the clamping and release of the pole group. The two independent motors, together with the two sets of lead screws, allow the movement of the first clamping part 201 and the second clamping part 202 to be controlled independently, facilitating the adjustment of the clamping position and clamping force.

[0028] In some embodiments of this utility model, the first drive motor 151 and the second drive motor 152 are respectively connected by a flexible coupling 155 and a first lead screw 153 and a second lead screw 154. Specifically, in this embodiment, the flexible coupling 155 can absorb the installation deviations between the first drive motor 151 and the first lead screw 153, including angular deviations, radial deviations, and axial deviations, thereby reducing the requirements for the machining accuracy and assembly accuracy of the clamping base 100.

[0029] In some embodiments of this utility model, the first lead screw 153 and the second lead screw 154 are respectively connected to the first clamping part 201 and the second clamping part 202 via a lead screw nut 156. Specifically, in this embodiment, the lead screw nut 156 transmission connection has a self-locking characteristic. When the first drive motor 151 stops rotating, the first lead screw 153 cannot drive the lead screw nut 156 in the reverse direction, thereby preventing the first clamping part 201 from accidentally retracting under external force and maintaining the stability of the clamping state.

[0030] In some embodiments of this utility model, the drive assembly 150 is provided with at least two guide rods 157, which are respectively arranged on both sides of the axial direction of the first lead screw 153 / second lead screw 154; the two guide rods 157 are connected to the side plate 120 and the partition plate 130 in sequence. Specifically, in this embodiment, the guide rods 157 provide the main support, and the first clamping part 201 and the second clamping part 202 are slidably disposed on the guide rods 157. By cooperating with the arrangement of the partition plate 130, stable support can be provided for the first clamping part 201 and the second clamping part 202. In this embodiment, the guide rods 157 bear the weight of the first clamping part 201 and the second clamping part 202 as well as the reaction force of the pole group, preventing the first lead screw 153 and the second lead screw 154 from bending and deforming. Guide rods 157 are arranged on both sides of the first lead screw 153 and the second lead screw 154 to form a symmetrical support structure. This structure can suppress the rotational tendency of the first clamping part 201 and the second clamping part 202 around the lead screw axis during movement, ensuring that the vertical plane remains parallel. The guide rods 157 are connected to the side plate 120 and the partition plate 130 in sequence, distributing the supporting force of the guide rods 157 to multiple structural components of the clamping base 100, thereby improving the overall rigidity. Specifically, in this embodiment, four guide rods 157 are provided, distributed around the periphery of the first lead screw 153 and the second lead screw 154. The distribution of the four guide rods 157 around the lead screws ensures that the first clamping part 201 and the second clamping part 202 are subjected to uniform force during sliding, avoiding jamming or wear due to unilateral force, and extending the service life of the mechanism.

[0031] In some embodiments of this utility model, locking blocks 240 are respectively provided on both sides of the upper part of the clamping block 220. The locking blocks 240 fix the upper part of the clamping block 220 in the mounting groove 211 of the fixing block 210 by locking bolts 250. Further, a contact block 260 is provided on one side of the clamping block 220. The contact block 260 is exposed on the outside of the fixing block 210 and abuts against the vibration element 230. Specifically, in this embodiment, the clamping plate 221 has a fork-shaped structure and a clearance slot 224 is provided on the clamping plate 221. Specifically, in this embodiment, the contact block 260 is exposed on the outside of the fixing block 210 and directly abuts against the vibration element 230, so that the mechanical vibration of the vibration element 230 is first transmitted to the contact block 260, and then transmitted to the end of the clamping plate 221 through the clamping block 220. This transmission path avoids the vibration energy being absorbed or attenuated by the fixing block 210, and improves the vibration transmission efficiency. The locking block 240 secures the upper part of the clamping block 220 to the mounting groove 211 via the locking bolt 250, forming a rigid connection. The preload of the locking bolt 250 prevents relative sliding between the clamping block 220 and the fixing block 210, ensuring continuous transmission of vibration energy between the contact block 260 and the clamping block 220, and between the clamping block 220 and the clamping plate 221, reducing energy loss due to gaps. The clamping plate 221 has a fork-shaped structure. The fork-shaped structure divides the clamping plate 221 into two independent vibration arms, each of which can independently generate micro-amplitude vibrations at its end. Compared to a single-volume clamping plate 221, the fork-shaped structure increases the number of contact points between the vibration end and the electrode group surface, while reducing the mass of each vibration arm. This makes it easier for the vibration energy output by the vibration element 230 to drive the vibration arm to generate high-frequency, small-amplitude vibrations, improving the dust removal effect. The combination of locking block 240, locking bolt 250, and contact block 260 forms a detachable rigid connection between clamping block 220 and fixing block 210, while ensuring that contact block 260 is always in the optimal force-bearing position outside the fixing block 210. When the vibration element 230 is working, the impact force on contact block 260 is directly transmitted longitudinally along clamping block 220, without generating a lateral component due to interference from fixing block 210, thereby maintaining the directionality and stability of vibration at the end of clamping plate 221.

[0032] In some embodiments of this utility model, the vibration element 230 is a combination of one or more of the following: an eccentric vibrator, an electromagnetic vibrator, and a pneumatic vibrator. Specifically, in this embodiment, the eccentric vibrator adopts a rotary excitation structure with a three-phase asynchronous motor and adjustable eccentric blocks at both ends. The motor drives the main shaft to rotate, and adjustable eccentric counterweights are installed at both ends of the shaft. During rotation, the periodic centrifugal force generated is converted into a stable linear excitation force. The eccentric vibrator has a simple mechanical structure, a large upper limit of output force, and no need for a reaction force application point. The electromagnetic vibrator inputs a periodically changing current into the electromagnet coil, generating a periodically changing excitation force between the excited component and the electromagnet. It is usually composed of an electromagnet core with a coil and an armature. The pneumatic vibrator uses compressed air as the vibration source and is divided into two types: piston reciprocating type and turbine type. The piston vibrator relies on compressed air to drive the piston to reciprocate within the body, transmitting the vibration force through the body. The turbine vibrator adopts an integrated structure of oblique turbine blades and eccentric counterweight. Compressed air is injected at high speed along the oblique guide grooves of the turbine blades, driving the turbine to rotate at high speed, and generating centrifugal excitation force through the eccentric counterweight. Specific models can be selected according to design requirements, which will not be elaborated here.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
