Description

Technical Field

[0001] This utility model relates to the field of sodium battery processing technology, specifically a composite electrode mounting mechanism for sodium batteries. Background Technology

[0002] With the increasing demand for energy storage, sodium batteries, as a promising new battery technology, have attracted widespread attention. In the production process of sodium batteries, the installation of composite electrodes is a crucial step.

The feeding mechanism is mounted on the feeding frame, and the distributing mechanism is located on one side of the feeding frame, below the feeding mechanism. The feeding mechanism is either a magnetic feeding mechanism or a roller feeding mechanism. The patent also discloses an electrode feeding installation structure, including an electrode installation robot, an electrode positioning mechanism, and the electrode feeding mechanism. The electrode positioning mechanism includes a first CCD positioning mechanism and a second CCD positioning mechanism. The first CCD positioning mechanism is located above the electrode feeding mechanism, and the second CCD positioning mechanism is located below the electrode installation robot. This utility model's electrode feeding mechanism and electrode feeding installation structure effectively ensure the accurate state of the electrodes picked up by the electrode installation robot, effectively ensuring the installation accuracy of the operation.

[0004] The above-mentioned technical solutions have a cumbersome traditional installation process. Each composite electrode requires manual adjustment of its position and angle multiple times, which takes a long time. In large-scale production, this seriously restricts the increase in production capacity. During the installation process, the traditional method lacks comprehensive protection measures for the composite electrode, which can easily cause damage to the electrode. Whether it is direct manual contact or improper operation of simple machinery, it may scratch the coating on the surface of the electrode or even deform the electrode, resulting in a decrease in electrode performance and thus affecting the performance and safety of the entire sodium battery.

[0005] Therefore, this utility model provides a composite electrode mounting mechanism for sodium batteries. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a composite electrode mounting mechanism for sodium batteries, thereby solving the aforementioned problems.

[0016] Beneficial effects

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) The sodium battery uses a composite electrode mounting mechanism. The motor in the adjustment mechanism is controlled by a controller. After starting, the motor drives the lead screw to rotate. Since the lead screw is threadedly connected to the moving block, the moving block will move along the sliding groove direction at the top of the L-shaped plate when the lead screw rotates. The connecting rod at the bottom of the moving block is fixed to the top of the connecting plate. Therefore, the movement of the moving block can drive the connecting plate and the entire extrusion mounting mechanism to move horizontally, thereby realizing flexible adjustment of the position of the pressing plate.

[0019] (2) The sodium battery uses a composite electrode installation mechanism. When the composite electrode is placed in the workpiece slot of the placement plate, the placement plate can be lowered a certain distance under the action of the lifting mechanism. The reset springs that are evenly and symmetrically distributed at the bottom of the placement plate play a buffering role to avoid the rapid descent of the placement plate from impacting the composite electrode. After installation, the placement plate can be raised and reset under the action of the reset spring, making it convenient to remove the installed battery. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4A composite electrode mounting mechanism for sodium batteries includes a worktable 1, a controller 2 on the outside of the worktable 1, a processing groove 3 inside the worktable 1, a pressing mounting mechanism 4 above the worktable 1, and an adjustment mechanism 5 on the outside of the worktable 1.

[0027] The extrusion installation mechanism 4 includes a rotating plate 41, an electric telescopic rod 42 fixedly connected to the bottom of the rotating plate 41, a piston rod 43 fixedly connected to the bottom of the electric telescopic rod 42, and a pressing plate 44 fixedly connected to the bottom of the piston rod 43.

[0028] The adjustment mechanism 5 includes an L-shaped plate 51, a connecting plate 52 fixedly connected to the top of the L-shaped plate 51, a motor 53 fixedly connected to the outside of the connecting plate 52, a lead screw 54 fixedly connected to the output end of the motor 53, a moving block 55 threadedly connected to the outside of the lead screw 54, a connecting rod 56 fixedly connected to the bottom of the moving block 55, a sliding groove 57 opened in the top of the L-shaped plate 51, a stabilizing plate 58 fixedly connected to the top of the worktable 1, a limiting groove 59 opened in the inner wall of the stabilizing plate 58, and a sliding rod 510 slidably connected inside the limiting groove 59.

[0029] Furthermore: the electric telescopic rods 42 are evenly distributed at the bottom of the operating plate 41, the L-shaped plate 51 is fixedly connected to the top of the workbench 1, the moving block 55 is slidably connected to the top of the L-shaped plate 51, the connecting rod 56 is slidably connected inside the slide groove 57, and the bottom of the connecting rod 56 is fixedly connected to the top of the operating plate 41, the stabilizing plate 58 is symmetrically distributed at the top of the workbench 1, the end of the slide rod 510 away from the limiting groove 59 is fixedly connected to both sides of the operating plate 41, and the electric telescopic rods 42 are evenly distributed below the operating plate 41.

[0030] It should be noted that the electric telescopic rod 42 is a high-precision servo electric telescopic rod 42, which can accurately control the stroke and thrust. It has a position feedback function, which can feed back the position information of the pressing plate 44 to the controller 2 in real time, ensuring that the pressure is always kept within the optimal range during the extrusion process, avoiding damage to the composite electrode due to excessive pressure, or insecure installation due to insufficient pressure. The surface of the pressing plate 44 is made of a special flexible material, such as a silicone coating, which can not only ensure full contact with the composite electrode, but also buffer and protect the electrode during extrusion, preventing scratches or deformation of the electrode surface.

[0031] Specifically: the lead screw 54 adopts a ball screw body, which has higher transmission efficiency and precision than ordinary lead screw bodies, enabling more precise position adjustment. At the same time, high-precision limit sensors are installed at both ends of the lead screw 54. When the moving block 55 reaches the limit position, the sensor will send a signal to the controller 2 in time to avoid over-driving of the motor 53 and causing damage to the equipment. In addition, the L-shaped plate 51 and the connecting plate 52 are made of high-strength aluminum alloy, which reduces the overall weight while ensuring structural strength, reduces the load on the motor 53, and improves the operating stability and response speed of the adjustment mechanism 5.

[0032] As a further improvement of this utility model, a placement plate 31 is installed inside the processing groove 3, and a workpiece groove 32 is opened inside the placement plate 31. A lifting mechanism 6 is provided on the outside of the placement plate 31. The lifting mechanism 6 includes a transmission rod 61. A moving groove 62 is opened inside the stabilizing plate 58. A pulling block 63 is fixedly connected to the outside of the transmission rod 61. A return spring 64 is fixedly connected to the bottom of the placement plate 31.

[0033] It should be noted that: the workpiece grooves 32 are evenly distributed inside the placement plate 31, and the workpiece grooves 32 are adapted to the pressing plate 44; one end of the transmission rod 61 is slidably connected inside the moving groove 62; the pulling block 63 is movably connected to the outside of the stabilizing plate 58; and the return springs 64 are evenly and symmetrically distributed between the placement plate 31 and the inner bottom wall of the processing groove 3.

[0034] Furthermore, the transmission rod 61 and the pulling block 63 are connected in an adjustable manner, which allows the position of the pulling block 63 to be flexibly adjusted according to the different sizes of the placement plate 31 and composite pole pieces, ensuring that the placement plate 31 can be pushed evenly during the descent. The return spring 64 is made of high elasticity and fatigue-resistant spring material and has undergone rigorous fatigue testing to ensure that the spring performance remains stable during long-term use and that there will be no weakening of elasticity or breakage, thereby ensuring that the placement plate 31 can be reliably raised and reset.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] Working principle: During the installation of the sodium battery composite electrode, the installation mechanism coordinates the operation of the extrusion installation mechanism 4, the adjustment mechanism 5 and the lifting mechanism 6 through the controller 2. First, the composite electrode and the battery casing are placed on the placement plate 31 in the processing groove 3 of the workbench 1. Then, each mechanism moves in sequence to complete the precise installation of the composite electrode.

[0037] The operator issues an installation command through controller 2, and the extrusion installation mechanism 4 starts working. The electric telescopic rods 42, which are evenly distributed at the bottom of the operating plate 41, extend synchronously after receiving the signal from controller 2. The extension of the electric telescopic rods 42 pushes the piston rod 43 connected to them to move downward. The piston rod 43 then drives the bottom pressing plate 44 to descend towards the composite electrode and battery shell in the processing groove 3. Because the electric telescopic rods 42 are evenly distributed, the descent of the pressing plate 44 can be guaranteed to be stable, avoiding tilting and damage to the electrode and shell. As the pressing plate 44 descends, it contacts the composite electrode and battery shell in the workpiece groove 32 of the placement plate 31. Under the continuous thrust of the electric telescopic rods 42, the pressing plate 44 applies uniform pressure to the composite electrode, so that the composite electrode is tightly attached to the battery shell, completing the extrusion action in the installation process, ensuring a stable connection between the electrode and the shell, optimizing the internal electrical connection of the battery, and improving battery performance. After the installation is completed, controller 2 controls the electric telescopic rods 42 to retract, driving the pressing plate 44 to rise and reset, ready for the next installation operation.

[0038] When the position of the extrusion mounting mechanism 4 needs to be adjusted according to the different specifications of composite electrode sheets and battery casings, the operator starts the motor 53 in the adjustment mechanism 5 through the controller 2. The motor 53 is fixed on the outside of the connecting plate 52. After starting, its output end drives the lead screw 54 to rotate. The lead screw 54 is threadedly connected to the moving block 55. When the lead screw 54 rotates, according to the thread transmission principle, the moving block 55 will move horizontally along the slide groove 57 on the top of the L-shaped plate 51. The L-shaped plate 51 is fixed on the top of the workbench 1 to provide stable support for the movement of the moving block 55. The connecting rod 56 fixedly connected to the bottom of the moving block 55 slides synchronously in the slide groove 57. The bottom of the connecting rod 56 is connected to the top of the operating plate 41. Therefore, the horizontal movement of the moving block 55 can drive the operating plate 41 and the entire extrusion mounting mechanism 4 to move horizontally, realize the flexible adjustment of the position of the pressing plate 44, so that it can be accurately aligned with the installation position of different specifications of products, and enhance the adaptability of the mounting mechanism to a variety of products.

[0039] After the composite electrode and battery casing are placed onto the placement plate 31, the lifting mechanism 6 starts to operate. The operator controls the transmission rod 61 to slide within the moving groove 62 inside the stabilizing plate 58. The pulling block 63, which is fixedly connected to the outside of the transmission rod 61, moves accordingly. The pulling block 63 contacts the placement plate 31 and pushes it down. The return springs 64, which are evenly and symmetrically distributed at the bottom of the placement plate 31, are compressed during the descent of the placement plate 31, playing a buffering role and preventing the placement plate 31 from impacting the composite electrode during rapid descent. The placement plate 31 stops after descending a certain distance, paving the way for subsequent pressing and installation operations. After preparation, once the composite electrode is installed and the extrusion installation mechanism 4 rises and resets, the transmission rod 61 is controlled to move in the opposite direction. The pulling block 63 no longer applies pressure to the placement plate 31. At this time, the reset spring 64 recovers its deformation, releases elastic potential energy, and pushes the placement plate 31 to rise and reset, making it convenient for operators to remove the installed sodium battery and enter the next round of production. At the same time, the cooperation between the stabilizing plate 58 and the internal limiting groove 59 and the slide rod 510 provides stable support for the operating plate 41 during the movement and operation of the extrusion installation mechanism 4, ensuring the stability of the operation of each mechanism.
