Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and more specifically to a temperature-changing device. Background Technology

[0002] In traditional material feeding mechanisms, the forklift loading method generally requires high alignment accuracy. This not only increases the difficulty of manual operation but also causes significant impact on the equipment mechanism during loading, thus limiting the equipment's lifespan and the reliability of its components. Furthermore, traditional equipment cannot meet the heating or cooling requirements of some battery processing steps. Because traditional temperature control mechanisms use heat dissipation components, the distance between these components and the pallet is unstable, making it difficult to maintain stable heat dissipation during critical processes such as formation, charging, and capacity testing.

[0003] Furthermore, traditional mechanisms typically employ fixed wind speeds or fluid parameters, making it impossible to flexibly adjust heat dissipation intensity based on battery temperature variations. Because traditional temperature control mechanisms use fixed heat dissipation components, the distance between the heat dissipation surface and the bottom of the tray must be maintained within a narrow range to ensure efficient heat transfer. Therefore, the tray's entry height into the workstation must precisely match this distance. When processes require switching between heating, ambient temperature, and cooling, differences in different temperature control modules lead to varying required distances, forcing the tray to adjust its entry height each time a process is switched. This significantly increases the vertical space requirements and structural complexity of the equipment. Therefore, existing technologies struggle to meet the high requirements for tray entry height space in processes with varying temperature control needs, resulting in a larger overall equipment height and consequently higher material costs.

[0004] The applicant's research revealed that current traditional equipment cannot meet the heating or cooling requirements of some battery processing steps in different battery manufacturing processes. Utility Model Content

[0044] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0045] like Figures 1-11 As shown, the variable temperature device of this utility model is applicable to a battery variable temperature needle bed, which includes a testing device 1 and a probe device 2.

[0046] Example 1

[0047] like Figures 1-4 As shown, the testing device 1 of this utility model is used for batteries and includes: a driving device 11, a sliding component 12, a base 13, and at least two probe mounting seats 14; the driving device 11 is fixedly mounted on the base; the sliding component 12 is connected to the driving device 11, and the driving device 11 drives the sliding component 12 to move on the base 13; the driving device 11 drives at least two probe mounting seats 14 to move in opposite directions or in the same direction through the sliding component 12, so as to realize the proportional adjustment of the probe spacing.

[0048] Understandably, the drive device 11 provides the power source for the entire testing device 1, ensuring the stability and reliability of the movement. The sliding component 12 is connected to the drive device 11 and forms a sliding pair with the base 13, realizing the linear movement of the sliding component 12 on the base 13. The drive device 11 drives at least two probe mounting seats 14 to perform synchronous reverse or same-direction linear movements through the sliding component 12, thereby realizing the proportional adjustment of the probe spacing to adapt to the testing requirements of batteries of different specifications and improve the versatility and applicability of the probe module 22.

[0049] In one embodiment, such as Figure 2 As shown, the driving device 11 includes a motor 111, a transmission assembly 112, a driven rod 113, and a linkage rod 114. The motor 111 serves as a power source. One end of the transmission assembly 112 is connected to the output shaft of the motor 111, and the other end of the transmission assembly 112 forms a rotary transmission pair with the driven rod 113. The driven rod 113 and the linkage rod 114 form a synchronous rotation mechanism through two pairs of meshing gear trains 115. Both ends of the linkage rod 114 are mounted on the base 13 through bearing seats. When the motor 111 drives the transmission assembly 112 to rotate, the driven rod 113 drives the linkage rod 114 to rotate synchronously through the gear trains 115, causing the sliding assembly 12 to generate linear displacement. Both ends of the driven rod 113 are provided with gear trains 115, and one end of the linkage rod 114 is meshed with the corresponding end of the driven rod 113 through the gear trains 115.

[0050] Furthermore, the transmission component 112 is a lead screw, one end of which is connected to the output shaft of the motor 111 via a coupling 1111.

[0051] Understandably, motor 111 serves as the power source for the entire drive unit 11. Motor 111 is fixedly mounted on base 13, and its output shaft is connected to one end of transmission assembly 112 via coupling 1111. The selection of motor 111 should be determined based on the maximum driving force and adjustment speed required by probe module 22 to ensure sufficient power output while meeting the requirements for rapid adjustment of probe spacing. The installation of motor 111 should ensure the concentricity of its output shaft connection with transmission assembly 112 to reduce vibration and errors during transmission, thereby improving the operational stability and accuracy of the device.

[0052] The transmission component 112 is a lead screw, one end of which is connected to the output shaft of the motor 111 via a coupling 1111. The function of the coupling 1111 is to accurately transmit the rotational motion of the motor 111 to the lead screw, while compensating for any minor coaxiality errors that may exist between the output shaft of the motor 111 and the lead screw, ensuring the smoothness and reliability of the transmission. The other end of the lead screw and the driven rod 113 form a rotary transmission pair, typically connected by bearings and a gear train 115. The specifications of the lead screw (such as pitch and diameter) are selected based on the adjustment stroke and load requirements of the probe module 22 during actual use to ensure that the required linear displacement and load-bearing capacity can be achieved under the drive of the motor 111.

[0053] Driven rod 113 is connected to transmission assembly 112. When transmission assembly 112 rotates, driven rod 113 rotates accordingly. Gear trains 115 are provided at both ends of driven rod 113. Each gear train 115 typically consists of two meshing gears, mounted on driven rod 113 and linkage rod 114 respectively. The gears on driven rod 113 and linkage rod 114 mesh with each other, forming a synchronous rotation mechanism to achieve power transmission between driven rod 113 and linkage rod 114. The parameters of gear train 115 (such as module, number of teeth, pressure angle, etc.) are selected according to the transmission ratio and torque requirements to ensure the accuracy and reliability of the transmission, while reducing noise and wear during gear meshing.

[0054] The linkage rod 114 is mounted on the base 13 at both ends via bearing seats 116. The bearing seats 116 provide stable support and rotational freedom for the linkage rod 114, ensuring its concentricity and stability during rotation. One end of the linkage rod 114 is meshed with the corresponding gear train 115 of the driven rod 113 via a gear train 115. When the driven rod 113 rotates, the linkage rod 114 rotates synchronously through the meshing transmission of the gear train 115. The rotational movement of the linkage rod 114, in turn, causes the sliding component 12 to produce linear displacement through its connection with the sliding assembly 12, thereby moving the probe mounting base 14 and adjusting the probe spacing.

[0055] like Figures 2-4As shown, when the motor 111 drives the transmission assembly 112 to rotate, the rotational motion of the transmission assembly 112 is transmitted to the driven rod 113 through a rotary transmission pair with the driven rod 113, causing the driven rod 113 to rotate. The gear train 115 at both ends of the driven rod 113 meshes with the gear train 115 on the linkage rod 114, so the rotation of the driven rod 113 drives the linkage rod 114 to rotate synchronously. The rotational motion of the linkage rod 114 is converted into linear motion of the sliding assembly 12 through its connection with the sliding assembly 12, thereby causing the sliding assembly 12 to produce linear displacement on the base 13. The sliding assembly 12 is connected to the probe mounting seat 14, so the probe mounting seat 14 moves accordingly, realizing proportional adjustment of the probe spacing. By controlling the rotation direction and speed of the motor 111, the synchronous reverse or same-direction linear motion of the probe mounting seat 14 can be achieved to meet the requirements of different battery tests for probe spacing.

[0056] In a preferred embodiment, such as Figure 2 As shown, the base 13 includes a base plate 131 and a support plate 132 disposed perpendicular to the base plate 131; the support plate 132 is used to support the drive device 11; two parallel slide rails 1311 are disposed on the upper surface of the base plate 131 along the pitch direction.

[0057] The base 13 includes a base plate 131 and a support plate 132 perpendicular to the base plate 131. The base plate 131, as the fundamental support structure of the entire testing device 1, is typically made of materials with certain strength and rigidity (such as aluminum alloy or steel) to ensure the stability and load-bearing capacity of the device. Two parallel slide rails 1311 are arranged on the upper surface of the base plate 131 along the pitch direction. The slide rails 1311 provide a track for the linear motion of the sliding component 12, ensuring the straightness and smoothness of the sliding component 12 during movement. The cross-sectional shape of the slide rails 1311 can be dovetail, T-shaped, or rectangular, etc., and their dimensions and surface roughness should meet the sliding requirements of the sliding component 12 while ensuring sufficient strength and wear resistance.

[0058] The support plate 132 is perpendicular to the base plate 131 and is mainly used to support the drive device 11. The structure and dimensions of the support plate 132 should be designed according to the weight and size of the drive device 11 to ensure the installation stability of the drive device 11. The support plate 132 can be connected to the base plate 131 by bolts, welding or other fixing methods to form an integral structure, thereby improving the rigidity and stability of the device.

[0059] Furthermore, the sliding assembly 12 includes a first sliding block 121 and a second sliding block 122; the first sliding block 121 and the second sliding block 122 respectively form a U-shaped structure with the probe mounting base 14; the openings of the U-shaped structures are respectively sleeved on the shoulder of the transmission assembly 112 and the linkage rod 114; the first sliding block 121 and the second sliding block 122 are symmetrically arranged along the axis of the slide rail 1311.

[0060] Understandably, the sliding assembly 12 includes a first sliding block 121 and a second sliding block 122. The first sliding block 121 and the second sliding block 122 respectively form a U-shaped structure with the probe mounting base 14. This U-shaped structure design increases the connection strength and stability between the sliding assembly 12 and the probe mounting base 14, while providing installation space and support for the transmission assembly 112 and the linkage rod 114. The openings of the U-shaped structure are respectively fitted onto the shoulder of the transmission assembly 112 and the linkage rod 114, axially positioning and supporting the sliding assembly 12 through the shoulder and the linkage rod 114, ensuring the stability and synchronization of the sliding assembly 12 during movement. The first sliding block 121 and the second sliding block 122 are symmetrically arranged along the axis of the slide rail 1311. The symmetrical arrangement of the sliding blocks ensures that the probe mounting base 14 is subjected to uniform force during movement, avoiding probe spacing adjustment errors caused by uneven force, and improving adjustment accuracy and stability.

[0061] In a further preferred embodiment, a first sliding member is provided on the outer side of the bottom of the U-shaped structure of the first sliding block 121; a first sliding groove is provided on the first sliding member to match the slide rail 1311 on the base plate 131 of the base 13, and the first sliding member slides in cooperation with the slide rail 1311 through the first sliding groove.

[0062] Understandably, a first sliding element is provided on the outer side of the bottom of the U-shaped structure of the first sliding block 121. The first sliding element is typically made of a wear-resistant, low-friction coefficient material (such as engineering plastics, bronze, etc.) to reduce friction and wear between it and the slide rail 1311, thereby improving the service life and sliding performance of the sliding element. A first groove is provided on the first sliding element to match the slide rail 1311 on the base plate 131. The shape and size of the first groove should match the slide rail 1311 to ensure that the sliding element can slide smoothly along the slide rail 1311 and maintain good contact and fit during sliding. The first sliding element slides into the slide rail 1311 through the first groove. This sliding fit allows the sliding assembly 12 to move smoothly and steadily along the variable pitch direction on the slide rail 1311, achieving precise adjustment of the probe spacing. Simultaneously, the fit clearance between the sliding element and the slide rail 1311 meets the standard to prevent the sliding assembly 12 from becoming loose or wobbling during movement, which would affect the adjustment accuracy.

[0063] Similarly, a second sliding member is also provided on the outer side of the bottom of the U-shaped structure of the second sliding block 122. The second sliding member has a second sliding groove that matches the slide rail 1311 on the base plate 131 of the base 13. The second sliding member slides with the slide rail 1311 through the second sliding groove to ensure the stable sliding of the second sliding block 122 on the slide rail 1311, and works in coordination with the first sliding block 121 to realize the synchronous linear movement of the probe mounting base 14.

[0064] In actual operation, when the drive device 11 is started, the motor 111 drives the transmission assembly 112 to rotate. Through gear transmission between the driven rod 113 and the linkage rod 114, the linkage rod 114 is driven to rotate. The rotational motion of the linkage rod 114 is converted into linear motion of the sliding assembly 12 through its connection with the sliding assembly 12 (such as a threaded connection or other transmission mechanism). The first sliding block 121 and the second sliding block 122 slide along the variable pitch direction on the slide rail 1311, respectively, driving the probe mounting base 14 to move, thereby realizing the proportional adjustment of the probe spacing. Since the sliding assembly 12 and the probe mounting base 14 form a U-shaped structure, and the sliding cooperation between the sliding component and the slide rail 1311 ensures the straightness and stability of the movement, the adjustment accuracy of the probe spacing is effectively guaranteed, which can meet the testing requirements of batteries of different specifications.

[0065] In a preferred embodiment, a fixed base 1321 and a strip-shaped through hole 1161 parallel to the direction of the slide rail 1311 are mounted on the support plate 132. The fixed base 1321 includes a sensor 124. Both the first sliding block 121 and the second sliding block 122 are provided with sensing plates 123. The fixed base 1321 extends into the strip-shaped through hole 1161 and can slide along the strip-shaped through hole 1161. The sensing plates 123 cooperate with the sensor 124 to achieve adjustment and positioning.

[0066] A mounting base 1321 is installed on the surface of the support plate 132. The length direction of the mounting base 1321 and the strip-shaped through hole 1161 is parallel to the slide rail 1311.

[0067] Both the first sliding block 121 and the second sliding block 122 are provided with sensing plates 123. The fixing seat 1321 extends into the strip-shaped through hole 1161 and can slide along the strip-shaped through hole 1161 to achieve the positioning of the probe spacing. The sensing plate 123 is installed on the sliding block by threaded connection, interference fit or other fixing methods. The shape of the strip-shaped through hole 1161 is usually elongated, and its length direction is consistent with the direction of the slide rail 1311. The setting position of the strip-shaped through hole 1161 on the support plate 132 should be precisely calculated and designed to ensure that the sensing plate 123 can move accurately along the direction of the slide rail 1311 during the sliding process, without affecting the installation and operation of other components. When the sliding block moves along the slide rail 1311, the strip-shaped through hole 1161 plays a guiding and limiting role for the sliding of the sensing plate 123. A sensor 124 is arranged on the fixed base 1321. When any sliding block moves the sensing plate 123 to align with the sensor 124, the sensing plate 123 blocks the light emitted by the sensor 124, causing the sensor 124 to receive a corresponding position signal. The sensor 124 immediately outputs a positioning signal to the external control system, thereby achieving precise adjustment and positioning of the end point of the stroke or any set position. This ensures that the sliding block moves smoothly and accurately along the slide rail 1311, preventing the sliding block from deviating or wobbling during movement, further improving the accuracy and stability of the probe spacing adjustment.

[0068] Furthermore, a scale 1312 is provided on the base plate 131 along the direction of the slide rail 1311; the scale 1312 is used to indicate the position of the sliding component 12 to assist in adjusting the spacing of the probe module 22.

[0069] A scale 1312 is provided on the base plate 131 along the direction of the slide rail 1311. The scale 1312 is typically made of metal or high-strength plastic and has clear, uniform graduation markings. The graduation unit can be millimeters, centimeters, etc., and the graduation accuracy should meet the requirements for probe spacing adjustment. The scale 1312 is mounted on the base plate 131 by bolts, adhesive, or other fixing methods, and is strictly parallel to the direction of the slide rail 1311 to ensure that the scale 1312 can accurately reflect the positional changes of the sliding component 12. The scale 1312 is used to indicate the position of the sliding component 12. Operators can intuitively understand the position of the sliding component 12 on the slide rail 1311 by observing the graduation markings on the scale 1312, thereby assisting in adjusting the spacing of the probe modules 22. When adjusting the probe spacing, the operator can precisely control the movement distance of the sliding component 12 by referring to the scale on the ruler 1312 according to the required target spacing, so as to achieve rapid and accurate adjustment of the probe spacing, improve adjustment efficiency and accuracy, and reduce the problem of inaccurate adjustment caused by insufficient experience or visual error.

[0070] The drive unit 11, fixedly mounted on the base 13, is activated, generating rotational power output. This power is transmitted to the connected sliding assembly 12 via a specific transmission mechanism. The sliding assembly 12 ensures its movement trajectory is a precise straight line. The power of the drive unit 11 is transmitted synchronously to and drives at least two probe mounting seats 14 via a linkage mechanism in the sliding assembly 12. When the drive unit 11 pushes the slider in a straight line, it forces the two probe mounting seats 14 to move in a straight line along their respective guide rails at the same speed but in opposite directions (one moving towards the center, the other away from the center). This directly changes the distance between the two probe mounting seats 14. When the linkage mechanism is designed for overall translation, the drive unit 11 drives the entire sliding assembly 12 and the probe mounting seats 14 fixed thereon to move in a straight line along the guide rail of the base 13 in the same direction. At this time, the relative distance between all the probe mounting seats 14 remains unchanged, but the position of the whole relative to the base 13 changes. In the synchronous reverse motion mode, due to the symmetry of the linkage mechanism, the absolute values ​​of the distances moved by the two probe mounting seats 14 are equal. Therefore, the change in the spacing between them is twice the moving distance of each mounting base, achieving linear proportional adjustment of the spacing (the adjustment amount is directly proportional to the input displacement of the drive device 11).

[0071] Example 2

[0072] like Figures 5-8 As shown, the probe device of this utility model is applicable to a battery tray and includes an outer frame 21, several sets of probe modules 22, and two or more straightening mechanisms 23. The probe modules 22 are inserted into the hollow area in the middle of the outer frame 21. Several reinforcing plates 24 are evenly spaced on the inner surface of the outer frame 21, and the lower end of each reinforcing plate 24 is connected to an adjusting block 241. The probe modules 22 are connected to the straightening mechanisms 23. Several adjusting plates 231 are provided on the straightening mechanisms 23, and adjusting tracks 232 are provided on each adjusting plate 231. The adjusting blocks 241 are adapted to the adjusting tracks 232 and are connected to the adjusting tracks 232 for the straightening mechanisms 23 to adjust the battery tray 4.

[0073] Understandably, the outer frame 21, as the supporting structure of the entire device, is shaped to fit the battery tray 4 and is made of high-strength material to ensure the stability and durability of the device. A hollow area is provided in the middle of the outer frame 21. The shape and size of this area are designed according to the layout of the probe modules 22, providing sufficient space for the placement of the probe modules 22, allowing them to be smoothly inserted. The probe modules 22 are used to perform various detection operations on the battery tray 4. Several sets of probe modules 22 are inserted in the hollow area in the middle of the outer frame 21. Each set of probe modules 22 includes a positive electrode probe assembly 221, a negative electrode probe assembly 222, a temperature probe assembly 223, and a negative pressure assembly 224. Among them, the positive electrode probe assembly 221 and the negative electrode probe assembly 222 are used to detect the electrode state of the battery to ensure the normal charging and discharging of the battery; the temperature probe assembly 223 is used to monitor the temperature change of the battery in real time during operation to prevent the battery from being dangerous due to excessive temperature; the negative pressure assembly 224 is used to extract the gas generated during the battery process to maintain the stability of the internal environment of the battery.

[0074] The probes of the probe assembly pass through the adjustment plate 231 at equal intervals and are arranged sequentially on the same horizontal plane. This arrangement allows the probe module 22 to perform comprehensive and uniform testing of the battery tray 4, improving the accuracy and reliability of the testing. The shape and size of the probes can be adjusted according to the shape and size of the terminals in actual production to ensure close contact with the terminals and achieve accurate testing.

[0075] There are two or more straightening mechanisms 23, used to adjust and fix the position of the battery cell, ensuring that the probe module 22 can accurately contact the battery cell terminal, injection port, and other parts. The straightening mechanism 23 is provided with several adjustment plates 231, and the adjustment plates 231 are provided with adjustment rails 232. The shape and size of the adjustment rails 232 are designed according to the shape and size of the adjustment blocks 241, so that the adjustment blocks 241 can be adapted to the adjustment rails 232 and move along the rails.

[0076] The inner surface of the outer frame 21 is provided with several reinforcing plates 24 at equal intervals. The lower end of each reinforcing plate 24 is connected to an adjusting block 241, which is connected to an adjusting track 232. When adjusting the battery tray 4, the driving device 11 (such as a motor or cylinder) moves the adjusting block 241 along the adjusting track 232, thereby moving the straightening mechanism 23 as a whole, thus adjusting the position of the battery tray 4. The connection between the adjusting block 241 and the adjusting track 232 can be a sliding connection or a rolling connection to reduce friction and improve the accuracy and flexibility of the adjustment.

[0077] Reinforcing plates 24 are evenly distributed on the inner surface of the outer frame 21. Their function is to enhance the structural strength of the outer frame 21 and prevent deformation due to external forces during use, thereby ensuring the overall stability and reliability of the probe device 2. The shape and size of the reinforcing plates 24 are designed according to the shape and size of the outer frame 21 to ensure that they fit tightly against the outer frame 21 and provide good reinforcement. A protrusion 242 extends from the lower end of the reinforcing plate 24. The protrusion 242 allows the probe module 22 to be embedded inside the tray 4 during operation, further preventing interference between the probe module 22 and the tray 4 and ensuring that the probe module 22 can smoothly perform detection operations on the battery tray 4.

[0078] This embodiment features a straightening mechanism 23, which uses dynamic adaptive positioning to ensure precise alignment of the battery tray 4 during material loading, testing, and repositioning. In one embodiment, the straightening mechanism 23 includes a first straightening mechanism and a second straightening mechanism. The first straightening mechanism is located on the side of the outermost battery, with its guide end extending into the gap between the edge of the battery pack and the frame of the tray 4. The second straightening mechanism is located on the other side, with its guide end extending into the gap between two adjacent batteries. Because the horizontal width of the straightening mechanism is smaller than the gap width between the frame of the tray 4 and the edge of the battery pack, this design allows the guide end to effectively contact and guide the tray 4 or the side of the battery when inserted into the gap, thereby achieving radial (horizontal) position correction of the battery cells. To accommodate battery trays 4 of different sizes, the straightening mechanism 23 can move along a preset adjustment track 232 to adjust its relative position, ensuring compatibility with different specifications of trays 4.

[0079] Furthermore, the probe module 22 includes a positive probe assembly 221, a negative probe assembly 222, a temperature probe assembly 223, and a negative pressure assembly 224; the probe ends of the probe assemblies pass through the adjustment plate 231 at equal intervals. The positive probe assembly 221, the temperature probe assembly 223, the negative pressure assembly 224, and the negative probe assembly 222 are arranged sequentially on the same horizontal plane.

[0080] The probe module 22 is the core component of the probe device 2 of this invention, used for various detections and operations on the battery tray 4. The probe module 22 includes a positive electrode probe assembly 221, a negative electrode probe assembly 222, a temperature probe assembly 223, and a negative pressure assembly 224. These components work together to achieve comprehensive detection and process operations on the battery tray 4. The positive electrode probe assembly 221 is used to detect the positive electrode state of the battery, including electrical parameters such as voltage and current. This assembly includes a probe tip, connecting wires, and a signal processing unit. The probe tip is made of a highly conductive material to ensure good contact with the positive electrode of the battery. The connecting wires connect the probe tip to the signal processing unit, which amplifies, filters, and converts the detected signal for subsequent analysis and processing. The negative electrode probe assembly 222 is used to detect the negative electrode state of the battery, also including a probe tip, connecting wires, and a signal processing unit. The probe tip design is similar to that of the positive electrode probe assembly 221, using a highly conductive material to ensure good contact with the negative electrode of the battery. The negative electrode probe assembly 222 accurately measures parameters such as voltage and current at the battery's negative electrode, providing crucial data for battery performance evaluation. The temperature probe assembly 223 monitors the battery's temperature changes in real time during the manufacturing process. This assembly includes a temperature sensor, a probe tip, and a signal transmission line. The temperature sensor employs a high-precision thermistor or thermocouple to accurately measure the temperature of the cell surface. The probe tip is designed for close contact with the battery surface to ensure accurate temperature measurement. The signal transmission line transmits the signal collected by the temperature sensor to an external temperature display or control device for real-time monitoring of the battery's temperature status, preventing safety issues caused by excessively high temperatures.

[0081] The negative pressure component 224 is used to extract gases generated during the battery manufacturing process, maintaining a stable internal environment for the battery. The components of the probe module 22 are arranged sequentially on the same horizontal plane. In this embodiment, the arrangement is: positive electrode probe component 221, temperature probe component 223, negative pressure component 224, and negative electrode probe component 222. This arrangement ensures that the probe module 22 can perform comprehensive and uniform detection and operation on the battery tray 4. The positive electrode probe component 221 is located at the front, first contacting the positive electrode of the battery to detect electrical parameters. The temperature probe component 223 follows immediately, used to monitor the temperature change of the battery in real time during the detection process, ensuring the safety and reliability of the detection process. The negative pressure component 224 is located in the middle, responsible for extracting gases generated during the battery manufacturing process, maintaining a stable internal environment for the battery. The negative electrode probe component 222 is located at the rear, contacting the negative electrode of the battery to detect electrical parameters.

[0082] The probe tips of each probe assembly pass through the adjustment plate 231 at equal intervals, ensuring that the probe module 22 maintains a stable position during adjustment. The adjustment plate 231 has multiple through holes through which the probe tips extend to contact corresponding parts of the battery tray 4, such as the cell terminals and electrolyte inlets. The spacing and size of the through holes are designed according to the electrode spacing and size of the battery tray 4 to ensure accurate contact between the probe tips and the electrodes.

[0083] Furthermore, such as Figure 8 As shown, the negative pressure assembly 224 includes a negative pressure hose 2241, a hose clamp 2242, a hose connector 2243, a negative pressure cup 2244, a guide sleeve 2245, a negative pressure suction rod 2246, a connector 2247, and a negative pressure suction nozzle 2248. One end of the negative pressure hose 2241 is connected to the manifold 211 on the outer frame 21 via the hose connector 2249, and the other end of the negative pressure hose 2241 is connected to the connector 2246 via the hose clamp 2242. The head 2243; the bottom of the negative pressure cup 2244 is connected to one end of the negative pressure suction rod 2246, the guide sleeve 2245 is sleeved on the negative pressure suction rod 2246, and the negative pressure suction rod 2246 is connected to the negative pressure suction nozzle 2248; wherein, the connector 2247 is sandwiched between the negative pressure suction nozzle 2248 and the guide sleeve 2245, and the negative pressure suction nozzle 2248 is in direct contact with the battery filling port, and the gas generated during the battery process is extracted by negative pressure.

[0084] The negative pressure assembly 224 is mainly used to extract the gas generated during the battery manufacturing process to maintain a stable and clean internal environment for the battery. The specific structure and working principle of this assembly are as follows: The negative pressure hose 2241 is used to transmit negative pressure gas. One end of the negative pressure hose 2241 is connected to the manifold 211 on the outer frame 21 via a hose connector 2249. The manifold 211 serves as the interface for the negative pressure source, connecting to an externally provided negative pressure source to extract the gas generated during the battery manufacturing process. The hose connector 2249 adopts a quick-connect design for easy installation and maintenance, while ensuring a tight seal. The other end of the negative pressure hose 2241 is connected to the hose connector 2243 via a hose clamp 2242. In this embodiment, the hose clamp 2242 is a nut made of stainless steel, which can firmly fix the negative pressure hose 2241, preventing it from loosening or falling off during use due to negative pressure. The pipe fitting 2243 is used to connect the negative pressure hose 2241 and the negative pressure cup 2244 to ensure that the negative pressure gas can be smoothly transmitted to the negative pressure cup 2244.

[0085] Furthermore, the interior of the negative pressure cup 2244 is a vacuum chamber.

[0086] Understandably, the negative pressure cup 2244 has a vacuum chamber inside, used to store the gas or liquid extracted under negative pressure. The negative pressure cup 2244 is made of high-strength, vacuum-resistant material to ensure its stability and safety under negative pressure conditions. The bottom of the negative pressure cup 2244 is connected to one end of the negative pressure suction rod 2246. Through this connection, the negative pressure inside the negative pressure cup 2244 can be effectively transferred to the negative pressure suction rod 2246. The design of the negative pressure cup 2244 considers its connection method with the external negative pressure source and its sealing performance with the negative pressure suction rod 2246. The inner wall of the negative pressure cup 2244 is smooth, reducing resistance to gas flow and improving the transmission efficiency of negative pressure. Furthermore, a pressure sensor is also provided in the negative pressure circuit to monitor the magnitude of the negative pressure in real time, ensuring that the negative pressure remains within the process requirements. The guide sleeve 2245 is fitted onto the negative pressure suction rod 2246, serving a guiding and supporting function. The guide sleeve 2245 is machined with high precision to ensure the fit accuracy between it and the negative pressure suction rod 2246, allowing the negative pressure suction rod 2246 to move smoothly while maintaining good sealing. The negative pressure suction rod 2246 is a key component of the negative pressure assembly 224, used to transmit negative pressure to the negative pressure nozzle 2248 and contact the battery filling port. The negative pressure suction rod 2246 has an internal air passage for drawing negative pressure gas. The design of the air passage takes into account the smoothness and efficiency of gas flow, ensuring that negative pressure can be effectively drawn out from the negative pressure nozzle 2248.

[0087] The negative pressure nozzle 2248 is the end component of the negative pressure assembly 224 and directly contacts the battery filling port. The tight contact between the negative pressure nozzle 2248 and the battery filling port ensures a good seal. The shape and size of the negative pressure nozzle 2248 can be customized according to the design of the battery filling port in actual production to ensure accurate matching. A connector 2247 is sandwiched between the negative pressure nozzle 2248 and the guide sleeve 2245. The connector 2247 is made of elastic material and can buffer the mechanical impact between the negative pressure nozzle 2248 and the guide sleeve 2245, while ensuring an airtight connection between the negative pressure nozzle 2248 and the negative pressure suction rod 2246. The negative pressure nozzle 2248 communicates with the negative pressure suction rod 2246 through the connector 2247, ensuring that negative pressure gas can be smoothly extracted from the negative pressure nozzle 2248. During operation, an external negative pressure source extracts gases generated during the battery manufacturing process through manifold 211 and negative pressure hose 2241. The negative pressure within the negative pressure cup 2244 is transmitted to the negative pressure suction nozzle 2248 via the negative pressure suction rod 2246 and extracted from the nozzle. The negative pressure suction nozzle 2248 is in close contact with the battery filling port, using negative pressure to extract gases generated during the battery manufacturing process, maintaining a stable and clean internal environment for the battery. The entire negative pressure assembly 224 is designed with airtightness, durability, and ease of operation in mind, ensuring efficient and stable operation during the battery manufacturing process.

[0088] In practical applications, the negative pressure nozzle 2248 is in direct, tight contact with the battery filling port, extracting the gas generated during the battery manufacturing process through negative pressure. This design not only effectively improves the safety of battery production but also significantly enhances production efficiency, fully demonstrating the significant advancements and application advantages of the negative pressure component 224 in the battery manufacturing process. In one embodiment, the negative pressure cup 2244 and the negative pressure suction rod 2246 are integrally formed. The integrally formed negative pressure cup 2244 and negative pressure suction rod 2246 have the following beneficial effects: First, it reduces the length of the negative pressure hose 2241 between the negative pressure suction rod 2246 and the negative pressure cup 2244, thereby reducing the cost of using the negative pressure hose 2241; Second, it effectively reduces the residual electrolyte content in the negative pressure hose 2241 during the negative pressure process, reducing the probability of leakage of the negative pressure component 224; Third, it reduces the number of interfaces in the negative pressure system, thereby improving the overall airtightness and stability of the negative pressure system, making the system more reliable; Fourth, the integral design reduces the assembly volume of the component, improving the convenience of later maintenance and disassembly.

[0089] It should be noted that the connection between the negative pressure component 224 and the manifold 211 has been optimized from a fixed connector to a universal rotating connector, which can adapt to negative pressure hoses 2241 coming from different angles and prevent electrolyte residue from being caused by bending of the negative pressure hoses 2241.

[0090] Furthermore, a boss 242 extends from the lower end of the reinforcing plate 24. The boss 242 allows the probe module 22 to be embedded inside the tray 4 when it is working, thereby preventing the probe module 22 from interfering with the tray 4.

[0091] Understandably, the reinforcing plate 24 is an important structural component inside the outer frame 21. The reinforcing plate 24 enhances the structural strength of the outer frame 21, ensuring the stability and reliability of the entire probe device 2 during operation. The reinforcing plate 24 is made of high-strength material to withstand various external forces that may be encountered during use. The reinforcing plates 24 are evenly spaced on the inner surface of the outer frame 21, and their shape and size are optimized according to the internal space of the outer frame 21. A boss 242 extends from the lower end of the reinforcing plate 24. This boss 242 is a specially designed part of the reinforcing plate 24, and its main function is to ensure that the probe module 22 can be accurately embedded inside the tray 4 during operation, avoiding interference between the probe module 22 and the tray 4. The boss 242 can be trapezoidal or rectangular. Its upper surface smoothly transitions to the lower end of the reinforcing plate 24 to ensure the integrity and aesthetics of the structure. The sides of the boss 242 are designed with an appropriate slope to facilitate its smooth embedding inside the tray 4. The height of the boss 242 is adjusted according to the working height of the probe module 22 to ensure that the probe module 22 can accurately contact the battery cell terminals, liquid injection ports and other parts on the battery tray 4 when it is working.

[0092] When the probe device 2 is in operation, the probe module 22 is embedded into the tray 4 via the boss 242 at the lower end of the reinforcing plate 24. The shape and size design of the boss 242 ensures that the probe module 22 will not collide or interfere with other parts of the tray 4 during operation, thus protecting the probe module 22 and the tray 4 from damage. Guided by the boss 242, the probe module 22 can more accurately position itself to the battery terminal, liquid injection port, and other parts inside the tray 4, improving the accuracy of detection and operation. The design of the boss 242 increases the contact area between the probe module 22 and the tray 4, improving the stability of the entire device during operation and reducing errors caused by vibration or other external forces. During installation, the compatibility between the boss 242 and the interior of the tray 4 is crucial. Through precise machining and adjustment, it is ensured that the boss 242 can be smoothly embedded into the interior of the tray 4 and fit tightly with the internal structure of the tray 4. In addition, the design of the boss 242 also considers the maintainability of the device, facilitating disassembly and replacement when necessary.

[0093] Furthermore, the horizontal width of the straightening mechanism 23 is designed to be smaller than the gap width between the tray 4 frame 41 and the edge of the battery pack.

[0094] Understandably, the horizontal width of the straightening mechanism 23 is designed to be smaller than the gap width between the edge 41 of the tray 4 and the edge of the battery pack. This design allows the straightening mechanism 23 to smoothly enter the interior of the tray 4 without interfering with the battery pack, and to straighten and fix the battery cells on the battery tray 4. The shape and size of the straightening mechanism 23 are designed according to the shape and size of the battery tray 4 to ensure that the probe module fits tightly with the battery cell terminal, and at the same time, the negative pressure suction nozzle fits tightly with the liquid injection port to achieve a stable straightening effect.

[0095] Furthermore, the straightening mechanism 23 is provided with a scale 1312, which is used to adjust the spacing of the probe module 22.

[0096] Understandably, the straightening mechanism 23 is also equipped with a scale 1312, which is used to indicate the position of the adjustment block 241 on the adjustment track 232, thereby achieving precise adjustment of the spacing of the probe modules 22. The scale of the scale 1312 is clear and accurate. By observing the scale on the scale 1312, the operator can intuitively understand the spacing adjustment of the probe modules 22, ensuring that the probe modules 22 can accurately contact the battery cell terminals, liquid injection ports, and other parts, thereby improving the accuracy and reliability of the detection.

[0097] Example 3

[0098] like Figures 9-10As shown, the present invention discloses a temperature-regulating device suitable for battery trays, comprising a lifting frame 5 and a temperature-regulating component 32; the lifting frame 5 is used to support the battery tray; the temperature-regulating component 32 is connected to the lifting frame 5, and the temperature-regulating component 32 includes an air duct 321, a fan 322, and a temperature regulator 323; the fan 322 is installed at the end of the air duct 321; the temperature regulator 323 is provided with a medium pipe 324, which is used to load a temperature-regulating medium.

[0099] Understandably, when the battery tray 4 is placed on the lifting frame 5, the temperature control component 32 begins to operate. The air duct 321 serves as a gas guide channel, and the fan 322 activates, drawing air through the duct 321 into the temperature controller 323. In the temperature controller 323, the air comes into contact with the temperature-regulating medium, which absorbs or releases heat according to the temperature requirements of the battery tray 4, thereby regulating the air temperature. The fan 322 then directs the regulated air towards the battery tray 4, heating or cooling it to achieve the desired temperature range. By adjusting the fan speed 322 and the type and state of the temperature-regulating medium, the temperature of the battery tray 4 can be precisely controlled, ensuring the battery operates at its optimal operating temperature. This variable temperature device 3 effectively regulates the temperature of the battery tray 4, improving battery performance and lifespan, while also offering high flexibility and adaptability to meet temperature control needs in various scenarios.

[0100] The lifting frame 5 is made of high-strength aluminum alloy, which has good corrosion resistance and light weight, while ensuring sufficient structural strength to support the battery tray 4. The frame has a rectangular shape, and the surface is treated with plastic spraying to enhance surface corrosion resistance and improve appearance. The temperature control component 32 is connected to the lifting frame 5 by bolts or snap-fit, ensuring that the temperature control component 32 will not loosen during operation.

[0101] The air duct 321 is made of high-temperature and corrosion-resistant materials, such as stainless steel or high-strength plastic. Its inner surface is smooth to reduce airflow resistance and improve airflow transmission efficiency. The cross-sectional shape of the air duct 321 can be rectangular or flared. One end of the air duct 321 is connected to the thermostat 323, and the other end is connected to the fan 322. In this embodiment, the fan 322 is a high-efficiency, energy-saving DC brushless fan. This fan 322 has a long service life and low noise. Its speed can be adjusted according to the temperature requirements of the battery tray 4. For example, when the battery needs rapid cooling, the fan 322 can operate at high speed; when maintaining a stable battery temperature, the fan 322 can operate at low speed. The blades of the fan 322 adopt a special aerodynamic design, which can generate a large air volume. The blades are made of high-strength plastic or aluminum alloy, with good resistance to deformation. The motor of the fan 322 is equipped with a temperature sensor. When the motor temperature is too high, it can automatically reduce the speed or stop working to protect the fan 322 itself.

[0102] The thermostat 323 is equipped with multiple medium tubes 324, which divide the interior of the medium tubes 324 into multiple small chambers, each of which is filled with a temperature-regulating medium. These chambers are connected by tiny channels, allowing the temperature-regulating medium to flow between the chambers, thereby achieving uniform heat distribution.

[0103] The medium tube 324 is made of high-temperature and corrosion-resistant stainless steel. Its wall thickness is uniform, allowing it to withstand certain pressure. The medium tube 324 is rectangular or cylindrical in shape.

[0104] The medium pipe 324 has a spiral guide channel inside. When the temperature-regulating medium flows inside the pipe, the guide channel enables the medium to generate a spiral motion, increasing the contact area between the medium and the pipe wall and improving heat transfer efficiency. For example, compared with straight flow, spiral motion can increase the contact time between the temperature-regulating medium and the pipe wall by 35%, thereby more effectively absorbing or releasing heat.

[0105] When the battery tray 4 needs cooling, the temperature-regulating medium (such as a liquid) in the temperature controller 323 begins to absorb heat, and its temperature gradually rises. The fan 322 starts, blowing air from the end of the air duct 321 to the beginning. When the air passes through the temperature controller 323, it comes into contact with the temperature-regulating medium, which absorbs heat from the air, thus lowering the air temperature.

[0106] The fan 322 blows the cooled air through the air duct 321 to the battery tray 4 to cool the battery and effectively reduce the battery temperature.

[0107] When the battery tray 4 needs to be heated, the temperature-regulating medium (such as a heated liquid or solid particles after a phase change) in the temperature controller 323 begins to release heat. The fan 322 also starts, blowing air from the end of the air duct 321 towards the beginning. As the air passes through the temperature controller 323, the temperature-regulating medium transfers heat to the air, raising its temperature. The heated air is then directed by the fan 322 through the air duct 321 towards the battery tray 4, heating the battery and raising its temperature to the required operating temperature range.

[0108] In one embodiment, the temperature-changing device 3 further includes a feeder 31; the feeder 31 includes a roller frame 317, a roller group 311, a front guide plate 312, a side guide plate 313, a rear guide plate 314, an inlet roller 315, and a press baffle 316; the inlet roller 315, the front guide plate 312, and the press baffle 316 are arranged on a fixed frame 318 and are on the same horizontal line; the inlet roller 315 and the front guide plate 312 are used to guide the battery tray 4 into the feeder.

[0109] Understandably, such as Figures 9-10As shown, the roller frame 317 has a frame structure, facilitating the installation and maintenance of the roller assembly 311. The dimensions of the roller frame 317 are customized according to the dimensions of the battery tray 4 and the feeding path to ensure that the battery tray 4 can pass smoothly. The roller assembly 311 consists of multiple roller groups 311, each roller is mounted on an independent bearing to ensure flexible rotation. The front guide plate 312 is located at the front end of the roller frame 317, on the same horizontal line as the inlet roller 315. Its shape is arc-shaped or inclined, used to guide the battery tray 4 smoothly into the roller assembly 311. In this embodiment, the front guide plate 312 is made of stainless steel or aluminum alloy, and the surface is polished to reduce friction with the battery tray 4. Side guide plates 313 are installed on both sides of the roller frame 317 to limit the lateral movement of the battery tray 4 during the conveying process, ensuring that the tray 4 moves along the predetermined path. The height of the side guide plates 313 matches the height of the battery tray 4, and its shape is a straight plate or a plate with a certain curvature to accommodate different shapes of trays 4. The rear guide plate 314 is located at the rear end of the roller frame 317 and is used to further guide the battery tray 4 into the air duct 321 area of ​​the temperature control device 3. In this embodiment, the rear guide plate 314 is also made of stainless steel or aluminum alloy with a smooth surface to reduce friction with the tray 4. The inlet roller 315 is mounted on the fixed frame 318 and is on the same horizontal line as the front guide plate 312 and the press baffle 316. The diameter and material of the inlet roller 315 are the same as those of the rollers in the roller assembly 311, and it is used to initially guide the battery tray 4 into the feeder 31. The rotation speed of the inlet roller 315 can be controlled by a motor to ensure that the tray 4 can enter the conveying system smoothly. The press baffle 316 is located between the inlet roller 315 and the front guide plate 312 and is used to prevent the battery tray 4 from tilting or deviating when entering the conveying system. The shape of the press baffle 316 is rectangular or arc-shaped, and its height can be adjusted according to the height of the battery tray 4. The press baffle 316 is made of high-strength plastic or aluminum alloy, and has good elasticity and wear resistance. The press baffle 316 is fixed to the bottom frame 319 with screws, and can automatically adjust the pressure according to the shape of the pallet 4 to ensure that the pallet 4 remains stable during the conveying process.

[0110] When the battery tray 4 enters the feeder 31, it first contacts the inlet roller 315. Driven by a motor, the inlet roller 315 begins to rotate, conveying the tray 4 forward. Driven by the inlet roller 315, the tray 4 enters the roller assembly 311 along the arc or slope of the front guide plate 312. The shape and angle design of the front guide plate 312 ensures a smooth transition of the tray 4 into the roller assembly 311, preventing jamming or collisions during entry. The side guide plate 313 begins to function after the tray 4 enters the roller assembly 311, restricting the lateral movement of the tray 4 and ensuring that it moves along the centerline of the roller assembly 311. The height and shape of the side guide plate 313 can be finely adjusted according to the size of the tray 4 to accommodate different specifications of battery trays 4. The tray 4 continues to move forward under the conveying of the roller assembly 311, eventually reaching the rear guide plate 314. The rear guide plate 314 further guides the tray 4 into the air duct 321 area of ​​the temperature control device 3, ensuring that the tray 4 can accurately enter the effective range of the temperature control component 32. The pressure plate baffle 316 begins to work between the tray 4 entry roller 315 and the front guide plate 312. The pressure plate baffle 316 prevents the tray 4 from tilting or deviating when entering the conveying system.

[0111] Furthermore, the roller assembly 311 is used to assist the battery tray 4 in rolling feeding, and the rear guide plate 314 is used for positioning the battery tray 4; wherein, the press baffle 316 is used to limit the battery tray 4 after it is in place.

[0112] The roller assembly 311 consists of multiple evenly distributed rollers, each mounted on a roller frame 317 via an independent bearing. When the battery tray 4 enters the roller assembly 311, the rollers begin to rotate under the friction of the tray 4, assisting the tray 4 in rolling along a predetermined path. In one embodiment, the rotation speed of the roller assembly 311 can be controlled by a motor to adapt to different feeding speed requirements. For example, during rapid feeding, the roller assembly 311 can rotate at high speed; during fine positioning, the roller assembly 311 can rotate at low speed to ensure the precise position of the tray 4.

[0113] Once the battery tray 4 reaches the designated position, the press baffle 316 secures the tray 4 in place. In one embodiment, the press baffle 316 is provided with an anti-slip rubber layer to effectively prevent the tray 4 from sliding and ensure that the tray 4 remains stable during the operation of the temperature regulating device 3.

[0114] The above configuration has the following beneficial effects: First, by adding a roller-feeding method to the traditional forklift feeding method, the alignment accuracy of manual pallet 4 feeding is reduced, which facilitates personnel operation and improves work efficiency; Second, the impact force of the feeder 31 on other mechanisms of the equipment is lower and more controllable, which can extend the service life of the mechanism and enhance the reliability of some parts of the equipment; Third, the roller-feeding method requires less space for the pallet 4 to enter, so the space for the pallet 4 to enter can be reduced accordingly, thereby reducing the height of the equipment and reducing the material cost of the equipment.

[0115] Furthermore, the temperature regulating component 32 is mounted on the lifting frame 5 through the feeder 31. The lifting frame 5 is connected to a starting device 51, which causes the lifting frame 5 to move vertically. The temperature regulating component 32 can move along with the vertical movement of the lifting frame 5. The roller assembly 311 is mounted on the roller frame 317, and the bottom of the roller frame 317 is connected to the bottom frame 319.

[0116] Understandably, the lifting frame 5 supports the temperature control component 32 and the feeder 31. The frame is rectangular or cubic in shape, with the specific shape designed according to the size and layout of the temperature control component 32 and the feeder 31. In this embodiment, the surface of the frame is treated with anti-corrosion measures, such as painting or hot-dip galvanizing, to prevent rusting in harsh environments. The frame has internal reinforcing ribs to improve its resistance to deformation. The actuation device 51 can be a hydraulic cylinder, a pneumatic cylinder, or an electric actuator. Taking a hydraulic cylinder as an example, its cylinder body is made of high-strength aluminum alloy, and the piston rod is made of stainless steel, which has good wear resistance and corrosion resistance. A sealing ring is installed inside the hydraulic cylinder to prevent hydraulic oil leakage. The hydraulic system of the hydraulic cylinder includes a hydraulic pump, hydraulic valves, and a hydraulic oil tank. The hydraulic pump is a piston pump or gear pump, which can provide stable hydraulic pressure. The hydraulic valve is used to control the extension and retraction speed and direction of the hydraulic cylinder. The lifting frame 5 is connected to the actuation device 51 via a connector 2247. The connector 2247 can be bolted, welded, or riveted. When the actuation device 51 operates, such as by extending or retracting the piston rod of a hydraulic cylinder, the lifting frame 5 moves vertically accordingly. The temperature control assembly 32 is located in the middle of the feeder 31 and mounted on the lifting frame 5; therefore, the temperature control assembly 32 moves with the vertical movement of the lifting frame 5. This design allows the temperature control assembly 32 to adjust its height as needed to adapt to different working scenarios. For example, during the feeding operation of the battery tray 4, the lifting frame 5 can descend to a lower position for easier placement of the tray 4; during temperature control, the lifting frame 5 can rise to a suitable position, enabling the temperature control assembly 32 to better regulate the temperature of the battery tray 4.

[0117] The bottom of the roller frame 317 is designed with a connection interface for connecting to the bottom frame 319. The connection interface can be a flange or a plug-in interface. For example, when using a flange connection, the flange has multiple bolt holes, and the roller frame 317 is securely fixed to the bottom frame 319 with bolts. The roller frame 317 is made of the same material as the lifting frame 5 and is treated with anti-corrosion coating. The roller frame 317 also has internal reinforcing ribs to improve its load-bearing capacity. For example, the reinforcing ribs of the roller frame 317 can be distributed in a grid pattern to evenly distribute the weight of the pallet 4.

[0118] Furthermore, the temperature-regulating medium can be a liquid (such as water, ethylene glycol, etc.) or a gas (such as nitrogen, etc.). For liquid temperature-regulating media, good fluidity allows for rapid circulation between the temperature controller 323 and the medium pipe 324, absorbing or releasing large amounts of heat. For example, water has a high specific heat capacity; when absorbing the same amount of heat, its temperature change is relatively small, making it suitable for applications requiring stable temperatures and economical.

[0119] For gaseous temperature-regulating media, temperature regulation is mainly achieved through expansion and compression. The gas expands when heated in the temperature controller 323, driving airflow and thus carrying away heat; during cooling, the gas contracts, absorbing heat from the surrounding environment. The advantage of this temperature-regulating medium is its light weight, making it suitable for battery tray 4 systems where weight is a critical factor.

[0120] The specific working principle is as follows: the airflow is constrained by the air duct 321 to form a certain flow direction, and the fan fixes this flow direction. When the airflow passes through the temperature controller 323, it exchanges heat with the liquid in the medium tube 324 of the temperature controller 323 through a process of convection-conduction-convection. The medium in the tube can be a low-temperature liquid or a high-temperature liquid. Different media are selected according to different battery processes. When cooling is required during the battery process, a low-temperature liquid is selected as the medium in the tube. Since the temperature of the airflow is higher than that of the liquid in the tube, when the airflow passes through the air duct 321, the low-temperature medium in the tube carries away the heat and is blown out by the fan after reaching the end.

[0121] When heating is required during the battery manufacturing process, the medium inside the tube is a high-temperature liquid. When air passes through the air duct 321, the high-temperature medium inside the tube raises the temperature of the air, and it is blown out by the fan after reaching the end.

[0122] The temperature control component 32 is installed on the bottom surface of the lifting frame 5 and rises and falls with the lifting frame 5. Therefore, the distance between the temperature control component 32 and the battery tray on the lifting frame 5 remains fixed, and stable heat dissipation conditions can be maintained during operation.

[0123] On the other hand, the temperature control component 32 can control the battery cooling effect in two ways. The first is to use an adjustable-speed fan, using a PWM signal to control the fan speed at the top of the lifting frame 5, thereby controlling the battery temperature. The second is to adjust the fluid speed and temperature inside the thermostat 323 pipe. By adjusting the water flow temperature at the water supply end or using a flow proportional valve to control the fluid speed inside the pipe, the temperature of the air after passing through the thermostat 323 is regulated, thereby controlling the battery temperature. The two control methods can be used individually or in combination, depending on the temperature to be controlled.
