Description

Technical Field

[0001] This invention relates to the field of lithium battery testing, and in particular to a square battery restraint tray with fixed-distance water circulation temperature control. Background Technology

[0002] With the rapid development of the lithium battery industry, battery quality and safety issues have attracted increasing attention. A crucial aspect of battery manufacturing for safe use is conducting charge and discharge tests to ensure that the battery's performance indicators meet the required standards.

[0003] During the charge-discharge testing of lithium batteries, the batteries placed in the fixture undergo four steps: charging, discharging, resting, and cycling. During this process, test probes inject a constant voltage and current into the battery. The electrolyte inside the lithium battery reacts chemically under the influence of the current, generating heat. The battery casing on the outer surface expands under the influence of the internal heating environment. Most existing square battery trays only serve to place and fix the batteries. During the charging and cycling steps, they rely solely on temperature probes to detect the surface temperature of the battery to determine its performance. If the temperature probe malfunctions or the battery itself has poor performance during manufacturing, the surface temperature may become too high or too low, and expansion may occur, posing a risk and affecting other batteries in the tray.

[0004] Therefore, when conducting charge and discharge tests on square lithium batteries, it is necessary not only to use a tray to uniformly compress the batteries in the expanded state to control their expansion and deformation, but also to have the function of timely temperature adjustment for batteries with abnormal temperatures. This requires a square battery restraint tray with fixed-distance water circulation temperature control. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a square battery restraint tray with fixed-distance water circulation temperature control. On one hand, it has the advantage of fixing and limiting the degree of battery expansion to prevent deformation. On the other hand, it also has the function of reducing battery charging temperature and detecting abnormally heated areas of the battery.

[0006] The present invention provides a square battery restraint tray with fixed-distance water circulation temperature control, characterized in that it comprises:

[0007] The clamping mechanism includes a tray frame, a transmission screw assembly, and a movable pressure plate. The transmission screw assembly is rotatably mounted on the left end of the tray frame, with the axis of the transmission screw assembly as the longitudinal direction. The power input end of the transmission screw assembly is connected to a power drive system, and the power output end of the transmission screw assembly is connected to the movable pressure plate for driving the movable pressure plate to move longitudinally. The movable pressure plate is slidably disposed in the tray frame for driving the shaping mechanism to clamp or release the square battery.

[0008] A shaping mechanism, disposed within the tray frame, comprises several interconnected shaping plates. These plates are arranged vertically between the movable pressure plate and the right end of the tray frame, connected to each other and slidably fitted to the tray frame. The two outermost shaping plates are fixed to the surfaces of the movable pressure plate and the right end of the tray frame facing the square battery, respectively. A clamping gap for holding the square battery is provided between adjacent shaping plates. Temperature control pipes are installed inside each shaping plate. The shaping mechanism, through the transmission screw assembly, provides a longitudinal clamping force to the battery tray, clamping the placed square battery.

[0009] A temperature control device is provided on the side of the shaping mechanism, including a main pipeline system, multiple branch pipeline systems, and an inlet / outlet water pipeline system. The main pipeline system is connected to the water supply system through the inlet / outlet water pipeline system, and a temperature sensor for detecting the water temperature in the main pipeline system is provided in the inlet / outlet water pipeline system. The main pipeline system is connected to the temperature control pipeline provided in the shaping plate through the branch pipeline system, and is used to control the temperature of the square battery clamped in the clamping gap.

[0010] Furthermore, the tray frame has opposing left and right end plates, and the bottom of the left and right end plates are connected to support plates for supporting the bottom of the square battery; a guide shaft is provided between the left and right end plates; the transmission screw assembly is rotatably inserted through the left end plate.

[0011] Furthermore, the shaping mechanism is divided into multiple circulating temperature control zones along the longitudinal direction, and each circulating temperature control zone is connected to a set of the diversion pipeline system. The shaping plate is connected to the main pipeline system through the corresponding diversion pipeline system.

[0012] Furthermore, the shaping plate has at least one groove on its surface facing the square battery; the groove is a vertically arranged through groove suitable for the square battery, and an insulating plate is laid on the surface of the groove; when the shaping mechanism presses, the grooves of two adjacent shaping plates can be joined to form a clamping gap that matches the shape of the square battery, which is used to clamp the battery while fitting against the surface of the square battery to prevent deformation caused by expansion.

[0013] Furthermore, the side of the shaping plate is provided with a temperature-controlled water inlet and a temperature-controlled water outlet. Both the temperature-controlled water inlet and the temperature-controlled water outlet are connected to the temperature-controlled pipeline. Water flows through the diversion pipeline system into the interior of the temperature-controlled pipeline. The outer wall of the shaping plate is made of a thermally conductive material for heat transfer in contact with the battery. At the same time, the internal temperature is regulated by the water flow to achieve a temperature control effect.

[0014] Furthermore, the main pipeline system includes an inlet pipe, an outlet pipe, a water guide block assembly, and inlet and outlet pipes;

[0015] The water guide block assembly includes a connecting rod and multiple water guide blocks. The two ends of the connecting rod are respectively fixed to the left end plate and the right end plate. The water guide blocks are divided into two groups, and the number of water guide blocks in the first group is the same as the number of circulating temperature control zones divided by the shaping mechanism. The water guide blocks in the first group and the water guide blocks in the second group are arranged alternately on the connecting rod.

[0016] Multiple water inlet pipes are sequentially connected to form a main water inlet pipe through the first group of water guide blocks; the water guide blocks of the first group are respectively connected to the temperature-controlled water inlet of the shaping plate through the diversion pipeline system of the corresponding area.

[0017] Multiple water outlet pipes are sequentially connected to form a main water outlet pipe through the second group of water guide blocks; the second group of water guide blocks are respectively connected to the temperature-controlled water outlet of the shaping plate through the diversion pipeline system.

[0018] Furthermore, the inlet and outlet water pipeline includes an inlet and outlet water connector, an inlet connecting pipe, and an outlet connecting pipe. The inlet and outlet water connector is provided with an inlet channel and an outlet channel. The inlet channel of the inlet and outlet water pipeline system is connected to the inlet end of the main inlet water pipeline through the inlet connecting pipe, and the outlet channel of the inlet and outlet water pipeline system is connected to the outlet end of the main outlet water pipeline through the outlet connecting pipe. A temperature sensor is provided at the outlet channel of the inlet and outlet water connector.

[0019] Furthermore, the diversion pipeline system includes an inlet diversion pipe, a shaping plate connecting pipe, and an outlet diversion pipe; within the same circulating temperature control area, the temperature control pipelines of two adjacent shaping plates are connected through the shaping plate connecting pipe, the remaining temperature control inlets are connected to the first group of corresponding water guide blocks through the inlet diversion pipe, and the remaining temperature control outlets are connected to the second group of corresponding water guide blocks through the outlet diversion pipe.

[0020] Furthermore, the water guide block is provided with three interconnected interfaces, namely a first interface, a second interface and a third interface, wherein the first interface is located at the top or bottom of the water guide block; the second interface and the third interface are located on opposite sides of the water guide block.

[0021] The beneficial effects of this invention are as follows: 1. Unlike the principle of ordinary tray-fixed batteries, the restriction of batteries within the tray is controllable by setting transmission screws and moving pressure plates, and because the clamping blocks are uniformly fitted to the square battery specifications, it is not easy for the batteries to deform during expansion; 2. During battery charging and discharging, the water circulation of the temperature control device is activated to perform regional water circulation temperature control on the batteries. While controlling the battery temperature, it can also detect areas of abnormal battery temperature rise and troubleshoot faulty batteries. Attached Figure Description

It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0032] The present invention provides a square battery restraint tray with fixed-distance water circulation temperature control, comprising:

[0033] The clamping mechanism 100 includes a tray frame 110, a transmission screw assembly 120, and a movable pressure plate 130. The tray frame 110 is a rectangular frame. The transmission screw assembly 120 is rotatably inserted through the left end of the tray frame, with the axial direction of the transmission screw assembly (i.e., the length direction of the tray frame 110) as the longitudinal direction and the width direction of the tray frame 110 as the transverse direction. The power input end of the transmission screw assembly 120 is connected to a power drive system, and the power output end of the transmission screw assembly 120 is connected to the movable pressure plate 130 to drive the movable pressure plate to move longitudinally. The movable pressure plate 130 is slidably disposed in the tray frame 110 to drive the shaping mechanism to clamp or release the square battery 400.

[0034] A shaping mechanism 200, disposed within the tray frame 110, includes several shaping plates 210. These shaping plates 210 are arranged vertically between the movable pressure plate 130 and the right end of the tray frame 110, and are slidably engaged with the tray frame. The two outermost shaping plates are fixed to the surface of the movable pressure plate facing the square battery and the surface of the right end of the tray frame facing the square battery. A clamping gap for holding the square battery is provided between adjacent shaping plates 210. A temperature control pipe 211 is provided inside each shaping plate 210. The shaping mechanism 220, through the transmission screw assembly 120, provides a longitudinal clamping force to the battery tray, clamping the placed square battery.

[0035] A temperature control device 300 is provided on the side of the shaping mechanism 200, including a main pipeline system 310, multiple sets of branch pipeline systems 320, and an inlet and outlet water pipeline system 330. The main pipeline system 310 is connected to the water supply system through the inlet and outlet water pipeline system, and a temperature sensor for detecting the water temperature in the main pipeline system is provided in the inlet and outlet water pipeline system 330. The main pipeline system 310 is connected to the temperature control pipeline 211 provided in the shaping plate 210 through the branch pipeline system 320, and is used to control the temperature of the square battery clamped in the clamping gap.

[0036] In one embodiment, the tray frame 110 has a left end plate 111 and a right end plate 112 facing each other. The bottom of the left end plate 111 and the right end plate 112 are connected to a support plate 113 for supporting the bottom of the square battery. Six guide shafts 114 of the same specification are provided between the left end plate 111 and the right end plate 112.

[0037] In one embodiment, each of the guide shafts 114 is longitudinally disposed between the left end plate 111 and the right end plate 112, and the six guide shafts 114 are divided into upper and lower layers, wherein the upper layer has four guide shafts arranged in parallel in the transverse direction; and the lower layer has two guide shafts arranged in parallel in the transverse direction.

[0038] In one embodiment, there are two sets of transmission screw assemblies 120, symmetrically arranged on the left end plate 111. The outer ends of the two sets of transmission screw assemblies 120 serve as power input ends and can be connected to an external power drive system to achieve automatic control. Alternatively, handles can be directly installed on the outer ends of the two sets of transmission screw assemblies 120 for manual control. The two sets of transmission screw assemblies 120 need to maintain synchronous and unidirectional transmission. The inner ends of the two sets of transmission screw assemblies 120 serve as power output ends and pass through the left end plate to connect with the movable pressure plate 130. The rotation of the transmission screw assembly 120 is converted into longitudinal reciprocating motion of the movable pressure plate 130, providing longitudinal driving force for the shaping mechanism 200.

[0039] In one embodiment, the movable pressure plate 130 is vertically disposed within the pallet frame 110 and located at the left end of the pallet frame 110; the movable pressure plate 130 is disposed laterally; the movable pressure plate 130 can be rotatably connected to the inner end of the transmission screw assembly 120, or can be directly screwed to the transmission screw assembly 120, etc., as long as the rotation of the transmission screw assembly 120 can be converted into the longitudinal movement of the movable pressure plate 130.

[0040] In one embodiment, the movable pressure plate 130 has through holes on both sides of its lateral side that can slide with the guide shaft, and the guide shaft 114 is slidably inserted in the through holes, so that the movable pressure plate 130 can slide sequentially along the guide shaft without obstruction.

[0041] In one embodiment, the shaping mechanism 200 is divided longitudinally into multiple cyclic temperature control zones, such as... Figure 7 As shown, the shaping mechanism 200 is divided into four circulating temperature control zones along the longitudinal direction, and each circulating temperature control zone is connected to a set of the diversion pipeline system 320. The shaping plate 210 is connected to the main pipeline system 310 through the corresponding diversion pipeline system 320.

[0042] In one embodiment, the shaping plate 210 has three grooves 213 on its surface facing the square battery 400. The three grooves 213 are arranged horizontally, and each groove 213 is a vertically arranged through groove suitable for the square battery. An insulating plate 212 is laid on the surface of the groove 213. When the shaping mechanism presses, the grooves of two adjacent shaping plates 210 can be joined to form a clamping gap that matches the shape of the square battery 400, which is used to clamp the battery while fitting against the surface of the square battery to prevent deformation caused by expansion.

[0043] In one embodiment, the shaping plate 210 is a rectangular plate, and the length direction of the shaping plate is consistent with the transverse direction of the pallet frame; both ends of the length direction of the shaping plate 210 and the upper edge of the shaping plate 210 are provided with lugs for sliding cooperation with the guide shaft, so that the shaping plate 210 arranged between the movable pressure plate 130 and the right end plate 111 can be directly hung on the guide shaft 114.

[0044] In one embodiment, the side of the shaping plate 210 is provided with a temperature-controlled water inlet and a temperature-controlled water outlet. Both the temperature-controlled water inlet and the temperature-controlled water outlet are connected to the temperature-controlled pipeline 211. Water flows through the diversion pipeline system 320 and enters the interior of the temperature-controlled pipeline 211. The outer wall of the shaping plate 210 is made of a thermally conductive material for contacting and transferring heat with the square battery 400. At the same time, the internal temperature is regulated by the water flow to achieve a temperature control effect.

[0045] In one embodiment, the main pipeline system 310 includes an inlet pipe 311, an outlet pipe 312, and a water guide block assembly 313;

[0046] The water guide block assembly 313 includes a connecting rod 315 and multiple water guide blocks 314. The two ends of the connecting rod 315 are respectively fixed to the left end plate 111 and the right end plate 112. The water guide blocks 314 are divided into two groups, and the number of water guide blocks 314 in the first group is the same as the number of circulating temperature control zones divided by the shaping mechanism 200, totaling four blocks. The water guide blocks of the first group and the water guide blocks of the second group are arranged alternately on the connecting rod 315. Multiple water inlet pipes 311 are connected sequentially through the water guide blocks of the first group to form a main water inlet pipe for water intake. The water guide blocks of the first group are respectively connected to the temperature control inlet of the shaping plate 210 through the diversion pipeline system 320 of the corresponding area.

[0047] Multiple water outlet pipes 312 are sequentially connected to form a main water outlet pipe through the second group of water guide blocks for water outlet; the second group of water guide blocks are respectively connected to the temperature control outlet of the shaping plate through the diversion pipeline system.

[0048] In one embodiment, the inlet and outlet water pipes 330 include an inlet and outlet water connector 331, an inlet connecting pipe 332, and an outlet connecting pipe 333. The inlet and outlet water connector 331 is provided with an inlet channel 334 and an outlet channel 335. The inlet channel 334 of the inlet and outlet water pipe system is connected to the inlet end of the main inlet water pipe through the inlet connecting pipe 332. The outlet channel 335 of the inlet and outlet water pipe system is connected to the outlet end of the main outlet water pipe through the outlet connecting pipe 333. A temperature sensor is provided at the outlet channel of the inlet and outlet water connector 331.

[0049] In one embodiment, the diversion pipeline system 320 includes an inlet diversion pipe 321, a shaping plate connecting pipe 322, and an outlet diversion pipe 323; within the same circulating temperature control area, the temperature control pipelines 211 of two adjacent shaping plates 210 are connected through the shaping plate connecting pipe 322, the remaining temperature control inlets are connected to the first group of corresponding water guide blocks through the inlet diversion pipe, and the remaining temperature control outlets are connected to the second group of corresponding water guide blocks through the outlet diversion pipe.

[0050] In one embodiment, the water guide block operates similarly to a T-joint. When controlling the temperature of incoming water within a region, only the joint connecting to the main flow pipe needs to be opened. When multiple regions converge, the joint connecting to the main flow pipe is closed after the water in one or two regions reaches a certain value, thus achieving water outflow from different regions. Then, the lower pipe is connected to pump the water away. Specifically, the water guide block 314 has three interconnected interfaces: a first interface 317, a second interface 318, and a third interface 319. The first interface 317 is located at the top or bottom of the water guide block; the second and third interfaces are coaxial and located on opposite sides of the water guide block.
