Description

Technical Field

[0001] This utility model relates to the technical field of battery formation and capacity testing equipment, and in particular to a battery formation and capacity testing needle bed. Background Technology

[0002] Before being manufactured and shipped, lithium batteries require a capacity formation process. The lithium batteries are placed in a battery tray, and then a capacity formation needle bed is used to perform the formation and capacity separation operations. The battery tray is a key structural component in the formation and capacity separation needle bed, primarily used to support, fix, and protect the batteries, while also possessing characteristics such as lightweight, corrosion resistance, and insulation.

[0003] However, in existing battery formation and capacity testing needle beds, the battery tray used to support the batteries does not form a smooth airflow channel. At the same time, the battery formation and capacity testing needle bed lacks an active air blowing auxiliary mechanism for targeted heat dissipation, resulting in poor heat dissipation of the internal batteries and poor temperature consistency of the batteries during charging and discharging. Utility Model Content

[0004] The main purpose of this invention is to propose a battery-forming capacitor needle bed, which aims to solve the problem of poor heat dissipation in existing battery-forming capacitor needle beds.

[0005] To achieve the above objectives, the present invention proposes a battery-forming and capacity-determining needle bed, comprising:

[0006] The main body of the needle bed;

[0007] A battery tray is provided on the needle bed body, and the battery tray is used to hold multiple batteries;

[0008] A heat dissipation assembly is disposed on the main body of the needle bed. The heat dissipation assembly is installed on both sides of the battery tray. The heat dissipation assembly includes multiple air supply devices and a mounting bracket. The multiple air supply devices are installed on the mounting bracket.

[0009] The battery tray has multiple first heat dissipation holes cut out at the positions corresponding to the battery tabs. The mounting bracket is movably mounted on the needle bed body, so that the mounting bracket drives multiple air supply devices to move and attach to the multiple first heat dissipation holes of the battery tray, so that air is blown towards the battery tabs.

[0010] Furthermore, the mounting bracket is rotatably mounted on the needle bed body, allowing the mounting bracket to switch back and forth between an extended position and a retracted position;

[0011] In the unfolded position, the heat dissipation components on both sides are open to the outside away from the battery tray; in the retracted position, the plurality of air supply devices are pressed against the heat dissipation holes of the battery tray.

[0012] Furthermore, a drive cylinder is installed on the main body of the needle bed, the drive cylinder drives a moving frame, a support seat is provided on the moving frame, and the mounting bracket is rotatably mounted on the support seat.

[0013] The mounting bracket is provided with a protrusion. When the drive cylinder drives the moving frame to rise, the protrusion can be pressed by the battery tray, causing the mounting bracket to rotate, thereby switching the mounting bracket from the unfolded position to the retracted position.

[0014] Furthermore, a first protruding post is provided on the support base, and a second protruding post is provided on the mounting bracket. A tension spring is connected between the first protruding post and the second protruding post. Under the tension of the tension spring, the mounting bracket switches from the retracted position to the extended position.

[0015] Furthermore, the support base is provided with a rotating shaft, and the mounting bracket is provided with a rotating shaft hole. The mounting bracket is rotatably connected to the support base through the rotating shaft passing through the rotating shaft hole.

[0016] Furthermore, the battery tray has a receiving cavity, in which a plurality of supporting liners are provided, and battery slots are provided on the supporting liners. The battery slots of any adjacent pair of supporting liners are used to support the battery, and a heat dissipation air duct is formed between each adjacent row of batteries.

[0017] Furthermore, the side of the battery tray has multiple first vent holes formed through it.

[0018] Furthermore, the supporting liner has multiple second vent holes formed through it.

[0019] Furthermore, each of the aforementioned heat dissipation ducts connects a portion of the first vent and the second vent, allowing air to flow along the side surface of the battery.

[0020] Furthermore, the support liner has a heat dissipation groove formed in the side wall of the battery slot.

[0021] Furthermore, the bottom of the battery tray is provided with a plurality of second heat dissipation holes, which are connected to the bottom of the heat dissipation duct.

[0022] Furthermore, the bottom of the battery tray is provided with multiple third heat dissipation holes, which are positioned directly opposite the battery.

[0023] Compared with existing technologies, the present invention provides a novel solution by densely distributing first heat dissipation holes at the positions corresponding to the battery tabs on the battery tray. These holes are arranged in a "comb" shape to improve the temperature uniformity of each battery, directing airflow directly to the battery tabs and enhancing heat dissipation efficiency. Simultaneously, the mounting bracket is movable, allowing multiple air delivery devices to be directly attached to the first heat dissipation holes on the battery tray, shortening the airflow distance, reducing airflow obstruction, and ensuring that the air delivery devices can blow air directly onto the first heat dissipation holes, further improving heat dissipation efficiency.

Detailed Implementation

[0034] 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.

[0035] Please see Figures 1 to 9 This utility model also proposes a battery-forming capacity needle bed.

[0036] The battery formation and capacity testing needle bed includes a needle bed body 100, a battery tray 200, and a heat dissipation assembly 300. The battery tray 200 is disposed on the needle bed body 100 and is used to support multiple batteries 210. The heat dissipation assembly 300 is disposed on the needle bed body 100, and heat dissipation assemblies 300 are installed on both sides of the battery tray 200. The heat dissipation assembly 300 includes multiple air supply devices 310 and a mounting bracket 320. The multiple air supply devices 310 are mounted on the mounting bracket 320. Multiple first heat dissipation holes 311 are hollowed out at the positions corresponding to the tabs of the batteries in the battery tray 200. The mounting bracket 320 is movably mounted on the needle bed body 100, so that the mounting bracket 320 drives the multiple air supply devices 310 to move and attach to the multiple first heat dissipation holes 311 of the battery tray 200, so that air is blown to the tabs 120 of the batteries 210.

[0037] Specifically, the needle bed body 100 is also equipped with a probe module 110. The probes in the probe module 110 are used to contact the tabs 120 of the battery 210 for charging and discharging. The air supply device 310 can be a fan or blower to supply air, which has a heat dissipation effect on the battery. It can be understood that the tabs 120 are the parts of the battery 210 where the heat is most concentrated during the formation or capacity grading process. By distributing dense first heat dissipation holes 311 at the positions corresponding to the battery tabs on the battery tray 200, and arranging multiple first heat dissipation holes 311 in a "comb" shape, it is more conducive to airflow and improves the temperature uniformity of each battery 210. The airflow is directed directly to the tabs 120 of the battery 210 where the heat is most concentrated, thereby improving the heat dissipation efficiency of the battery 210. Meanwhile, the mounting bracket 320 can be moved so that multiple air supply devices 310 can be directly attached to the first heat dissipation hole 311 of the battery tray 200 to actively assist in airflow and heat dissipation, shorten the airflow distance, reduce the obstruction of airflow, and ensure that the air supply device 310 can blow air directly at the first heat dissipation hole 311, thereby further improving the heat dissipation efficiency of the battery 210.

[0038] Please see Figures 1 to 3 Furthermore, the mounting bracket 320 is rotatably mounted on the needle bed body 100, allowing the mounting bracket 320 to switch back and forth between an extended position and a retracted position. In the extended position, the heat dissipation components 300 on both sides are open towards the outside, away from the battery tray 200. In the retracted position, multiple air supply devices 310 are pressed against the heat dissipation holes of the battery tray 200. Specifically, Figure 1 For the unfolding position, Figure 2 In the retracted position, the mounting brackets 320 on both sides are open to avoid the lifting and lowering of the battery tray 200. When the battery tabs 120 of the battery tray 200 are pressed against the test probes of the needle bed body 100, the mounting brackets 320 rotate from the retracted position to the extended position. The rotation of the mounting brackets 320 drives the air supply device 310 to directly press against the upper periphery of the battery tray 200 and blow air onto the first heat dissipation hole 311, making the distance between the air supply device 310 and the battery 210 shorter and improving heat dissipation efficiency.

[0039] Please see Figures 1 to 8Furthermore, a drive cylinder 400 is installed on the needle bed body 100, which drives a moving frame 410. A support base 411 is provided on the moving frame 410, and a mounting bracket 320 is rotatably mounted on the support base 411. A protrusion 321 is provided on the mounting bracket 320. When the drive cylinder 400 drives the moving frame 410 to rise, the protrusion 321 can be pressed by the battery tray 200, causing the mounting bracket 320 to rotate, thus switching the mounting bracket 320 from the extended position to the retracted position. Specifically, a tray support component 130 is also installed on the needle bed body 100, which supports the battery tray 200. When the drive cylinder 400 drives the moving frame 410 to rise, the protrusion 321 of the mounting bracket 320 on the moving frame 410 rises and is first pressed down by the battery tray 200. As the moving frame 410 continues to rise, the protrusion 321 of the mounting bracket 320 is pressured by the battery tray 200, causing the mounting bracket 320 to rotate until the air supply device 310 on the mounting bracket 320 is pressed against the side of the battery tray 200, ensuring that the air supply device 310 can directly press against the battery tray 200 and blow air. The moving frame 410 then drives the battery tray 200 and the heat dissipation component 300 to continue to rise. The drive cylinder 400 stops driving until the tabs 120 of the battery 210 in the battery tray 200 are pressed against the probes of the probe module 110. After the battery 210 has finished charging and discharging, the drive cylinder 400 drives the motion frame 410 to descend, which in turn drives the battery tray 200 and the heat dissipation component 300 to descend. After descending a certain distance, the battery tray 200 is supported by the tray support component 130 of the needle bed body 100 and stops descending. The battery tray 200 gradually loses its force on the protrusions 321 of the mounting bracket 320. At this time, the mounting bracket 320 can drive the air supply device 310 to switch from the retracted position to the extended position. With this setting, the heat dissipation component 300 has a high degree of automation in switching, and the position switching is completed by mechanical structure cooperation. There is no need to set up an additional power to drive the heat dissipation component 300 to switch back and forth between the extended and retracted positions, which reduces structural costs and improves heat dissipation efficiency.

[0040] Please see Figures 1 to 8Furthermore, the support base 411 is provided with a first protrusion 412, and the mounting bracket 320 is provided with a second protrusion 322. A tension spring 413 connects the first protrusion 412 and the second protrusion 322. Under the tension of the tension spring 413, the mounting bracket 320 switches from the retracted position to the extended position. Specifically, both the first protrusion 412 and the second protrusion 322 are cylindrical. Of course, the first protrusion 412 and the second protrusion 322 can also adopt other shapes, as long as the connection and fixing effect of the tension spring 413 is ensured. In the initial state, the mounting bracket 320 is in the extended position under the tension of the spring 413, and the air supply devices 310 on both sides are not pressed against the sides of the battery tray 200. When the drive cylinder 400 drives the moving frame 410 to rise, as the moving frame 410 rises, the protrusion 321 on the mounting bracket 320 of the moving frame 410 is pressed against the bottom of the battery tray 200. At this time, the spring 413 is in a stretched state, and the pressure exerted by the battery tray 200 on the protrusion 321 is greater than the tension of the spring 413, allowing the mounting bracket 320 to rotate until the air supply devices 310 press against the battery tray 200 to provide heat dissipation. The moving frame 410 drives the battery tray 200 and the heat dissipation assembly. The component 300 continues to rise until the tab 120 of the battery 210 in the battery tray 200 is pressed against the probe of the probe module 110, at which point the drive cylinder 400 stops driving. After the battery 210 has finished charging and discharging, the drive cylinder 400 drives the motion frame 410 to descend, which in turn drives the battery tray 200 and the heat dissipation component 300 to descend. After descending a certain distance, the battery tray 200 is supported by the tray support component 130 of the needle bed body 100 and stops descending, while the mounting bracket 320 continues to descend. At this time, the battery tray 200 gradually loses its force on the protrusion 321 of the mounting bracket 320. Under the action of the tension spring, the mounting bracket 320 drives the air supply device 310 to switch from the retracted position to the extended position.

[0041] Please see Figures 7 to 8 Furthermore, a rotating shaft 414 is provided on the support base 411, and a rotating shaft hole 323 is provided on the mounting bracket 320. The mounting bracket 320 is rotatably connected to the support base 411 through the rotating shaft 414 passing through the rotating shaft hole 323. In this way, the structure is stable and reliable, and the cost is low. The mounting bracket 320 can rotate relative to the support base 411, thereby enabling the air supply device 310 on the mounting bracket 320 to be pressed onto the battery tray 200.

[0042] Please see Figures 1 to 6Furthermore, the battery tray 200 has a receiving cavity 220, within which multiple supporting liners 221 are provided. Each supporting liner 221 has a battery slot 222. The battery slots 222 of any adjacent pair of supporting liners 221 support batteries 210, forming a heat dissipation duct 211 between adjacent rows of batteries 210. Specifically, the supporting liners 221 are the basic components for supporting the batteries 210, allowing space between the bottom of the batteries 210 and the base plate of the battery tray 200, further improving heat dissipation efficiency. Simultaneously, with each battery 210 spaced apart, the heat dissipation duct 211 blows air between each row of batteries 210, exchanging heat with the surfaces on both sides of the batteries 210, increasing the contact area between the batteries 210 and the air, and carrying away the heat from the batteries 210, further improving heat dissipation efficiency.

[0043] Please see Figures 5 to 6 Furthermore, the battery tray 200 has multiple first vent holes 223 extending through its side. Specifically, the shape of the first vent holes 223 can be rectangular, square, or other irregular shapes, and the shapes of each first vent hole 223 can also be different. By extending numerous first vent holes 223 through the battery tray 200, the contact area between the airflow and the battery 210 is increased, thereby improving the heat dissipation efficiency of the battery 210.

[0044] Please see Figure 9 Furthermore, the supporting liner 221 has multiple second vent holes 224 formed through it. Specifically, the shape of the second vent holes 224 can be rectangular, square, or other irregular shapes, and the shape of each second vent hole 224 can also be different. In this way, by using a through-hole design in various parts of the base component supporting the battery 210, the contact area between the battery 210 and the air is greatly increased, and the heat dissipation efficiency of the battery 210 is greatly improved under the action of the air supply device 310 or external wind.

[0045] Please see Figure 5 Furthermore, each heat dissipation duct 211 is connected to a portion of the first vent 223 and the second vent 224, allowing air to flow along the side surface of the battery 210. In this way, air can enter from the first vent 223 on one side of the battery tray 200, pass through the second vent 224, flow into the heat dissipation duct 211, and, following the airflow in the heat dissipation duct 211, flow through the second vent 224, enter the heat dissipation duct 211 located on the same plane, and flow through the second vent 224 of the supporting liner 221 before exiting from the first vent 223 of the battery tray 200. This promotes airflow within the heat dissipation duct 211 between adjacent rows of batteries 210, improving the heat dissipation efficiency of the batteries 210.

[0046] Please see Figures 1 to 8Furthermore, the support liner 221 has a heat dissipation groove 225 recessed into the side wall of the battery slot 222. In this way, by providing the heat dissipation groove 225 on the side wall of the battery slot 222, the contact area between the battery 210 and the battery slot 222 is reduced, thereby increasing the contact area between the battery 210 and the air and improving the heat dissipation efficiency of the battery 210.

[0047] Please see Figure 4 and Figure 6 Furthermore, the bottom of the battery tray 200 is provided with a plurality of second heat dissipation holes 226, which are connected to the bottom of the heat dissipation duct 211. Specifically, the second heat dissipation holes 226 at the bottom of the battery tray 200 are connected to the bottom of the heat dissipation duct 211 to promote airflow in the heat dissipation duct 211 and improve the heat dissipation effect of the heat dissipation duct 211 on the side of the battery 210.

[0048] Please see Figure 4 Furthermore, the bottom of the battery tray 200 is provided with multiple third heat dissipation holes 227, which are directly facing the battery 210. Thus, the tabs 120 of the battery 210 are cooled by the first heat dissipation hole 311, the bottom of the battery 210 is cooled by the third heat dissipation hole 227, and the sides of the battery 210 are cooled by the multiple second vent holes 224, the multiple third heat dissipation holes 227, and the heat dissipation ducts 211 of the battery tray 200. This achieves heat dissipation from the air to the entire surface of the battery 210, increases the contact area between the air and the various surfaces of the battery 210, and improves heat dissipation efficiency.

[0049] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. All equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
