[0048] At present, the battery manufacturing industry is accelerating its development, and automation and less manpower have become important development directions in the battery manufacturing field. By integrating advanced manufacturing technology and intelligent equipment, a highly automated and low-manpower-dependent production environment is constructed, and then the latest production forces are utilized to achieve a significant improvement in battery production efficiency while ensuring the consistency and reliability of product quality.

[0049] Taking a battery module composed of multiple cells as an example, the production process of the battery module includes a glue pressing process, which means that each cell is glued and then stacked in a specified direction, and then the stacked whole is heated and pressurized to cure the glue and complete the fixation of the battery module. The heating and pressurization process needs to be completed by a battery clamp, and the pressure plate of the battery clamp can provide high-temperature heating function while applying pressure to the stacked cells to accelerate the extension and curing of the glue.

[0050] In actual production, the glue pressing process has very high requirements for the parallelism of the pressure plate of the battery fixture. If the parallelism of the pressure plate does not meet the requirements, it will not be possible to apply stable pressure to the sides of the stacked cells, and further affect the conduction of the heating temperature to the stacked cells. At this time, the glue that is not evenly pressed and solidified will spread out in a dendrite shape, reducing the assembly quality of the battery module.

[0051] In response to the above problems, an embodiment of the present application provides a battery clamp testing tool and a battery production system, which tests the flatness of the clamping surface of the battery clamp and makes timely adjustments and maintenance to improve the uniformity of glue curing and the processing quality of the battery module.

[0052] See also Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of a battery fixture testing tooling according to an embodiment of the present application; Figure 2 for Figure 1 The internal structure schematic diagram of the battery fixture testing tool is shown. The battery fixture testing tool provided by the present application is first introduced below.

[0053] In a first aspect, an embodiment of the present application provides a battery clamp test tool, comprising a base 100, a covering member 200 and a test assembly, wherein the covering member 200 is arranged on one side of the base 100 along a first direction, and the covering member 200 is used to fit the clamping surface of the battery clamp; the test assembly is detachably connected to the base 100, and the test assembly is arranged in contact with the covering member 200 to obtain a parameter to be measured of the clamping surface of the battery clamp; wherein the parameter to be measured includes at least one of pressure data, temperature data and distance data to characterize the flatness of the clamping surface of the battery clamp.

[0054] The first direction is set perpendicular to the clamping surface of the battery clamp so that the covering piece 200 is parallel to the reference plane of the clamping surface of the battery clamp. When the covering piece 200 is attached to the clamping surface of the battery clamp, the uneven areas on the clamping surface will contact the covering piece 200 before or after other areas, thereby causing differences in the time for the test component to obtain the parameter to be measured or differences in the values ​​of the parameter to be measured, thereby achieving the characterization of the flatness of the clamping surface.

[0055] The covering member 200 refers to a member used to adhere to and cover the clamping surface of the battery clamp. It is understood that the covering member 200 has the same shape as the clamping surface of the battery clamp, or the orthographic projection of the clamping surface of the battery clamp on a plane perpendicular to the first direction falls within the orthographic projection of the covering member 200 on a plane perpendicular to the first direction, so that any area of ​​the clamping surface of the battery clamp is in contact with the covering member 200 of the test fixture, thereby improving the reliability of the test results.

[0056] The distance data includes at least one of the distance between the test assembly and the clamping surface of the battery fixture to be tested and the distance between the cover 200 and the clamping surface of the battery fixture to be tested.

[0057] The battery clamp test fixture provided in the embodiment of the present application can be loaded into the battery clamp and clamped by the battery clamp to test its clamping surface. The battery clamp test fixture adheres to the clamping surface through the covering 200, and obtains the parameters to be tested of the clamping surface of the battery clamp through the test component that is arranged in contact with the covering 200. The parameters to be tested are used to characterize the pressure uniformity, temperature uniformity or surface roughness of the clamping surface, thereby realizing the test of the flatness of the clamping surface, and timely repairing and adjusting the battery clamp according to the test results, thereby improving the processing quality of the glue pressing process.

[0058] According to some embodiments of the present application, the test assembly includes at least one detection element 301, and the detection element 301 is disposed in contact with the covering 200. The detection element 301 includes at least one of a pressure sensor, a temperature sensor, and a distance sensor.

[0059] Optionally, the test component includes a plurality of identical detection elements 301 , for example, the test component includes a plurality of pressure sensors; or, the test component includes a plurality of different detection elements 301 , for example, the test component includes at least one pressure sensor and at least one temperature sensor.

[0060] Optionally, the pressure sensor is at least one of a resistive strain pressure sensor, a capacitive pressure sensor, an inductive pressure sensor, a piezoelectric pressure sensor, a piezoresistive pressure sensor, and a Hall pressure sensor.

[0061] Optionally, the temperature sensor is a contact temperature sensor or a non-contact temperature sensor.

[0062] Optionally, the distance sensor is at least one of a laser distance sensor, an infrared distance sensor, an acoustic wave distance sensor, and a capacitive distance sensor.

[0063] Further optionally, when the detection element 301 is a distance sensor, the covering member 200 in contact with the detection element 301 is opened to expose the distance sensor to complete the detection.

[0064] Thus, the test component collects the parameter to be measured at at least one collection point on the clamping surface through at least one detection element 301, so as to achieve the characterization of the flatness of the clamping surface through at least one parameter to be measured.

[0065] According to some embodiments of the present application, two covering members 200 are provided, and the two covering members 200 are disposed on both sides of the base 100 along the first direction to simultaneously adhere to two clamping surfaces of the battery clamp.

[0066] Optionally, the detection element 301 is disposed in contact with two covering members 200 at the same time, and the detection element 301 can detect two clamping surfaces at the same time through the two covering members 200 to improve the detection efficiency. Exemplarily, the detection element 301 uses a pressure sensor, which can directly measure the pressure difference between the two clamping surfaces, and more intuitively shows the pressurization effect at different collection points between the two clamping surfaces of the battery clamp.

[0067] Optionally, the two covering members 200 have the same shape, or the two covering members 200 have different shapes.

[0068] Therefore, the battery clamp test tooling can simultaneously contact the two clamping surfaces of the battery clamp through the two covering parts 200, so as to simultaneously detect the flatness of the two clamping surfaces to improve the test efficiency, and at the same time improve the correlation between the parameters to be tested between the two clamping surfaces, thereby better analyzing the clamping stress distribution of the battery clamp to improve the quality of the glue pressing.

[0069] According to some embodiments of the present application, the covering member 200 is a hard plate material.

[0070] Optionally, the covering member 200 is made of a metal plate, which can form a shielding effect to reduce electromagnetic interference in the detection environment and improve detection accuracy.

[0071] Further optionally, the covering member 200 is made of an aluminum plate, which has excellent thermal conductivity and helps to improve the temperature detection accuracy. It is understandable that the aluminum plate is made of an aluminum plate or an aluminum alloy plate.

[0072] Further optionally, the thickness of the aluminum plate is less than 20 mm, so that the aluminum plate has better deformation transfer performance, which helps to improve the pressure detection accuracy.

[0073] As a result, the hard plate is not easily deformed under the clamping action of the battery fixture, which improves the rigidity of the test fixture to obtain better deformation transfer performance and improves the pressure measurement accuracy of the test fixture.

[0074] According to some embodiments of the present application, the test assembly is disposed on a side of the covering member 200 that is away from the clamping surface of the battery clamp.

[0075] Therefore, it is convenient to accommodate the test assembly in the base 100 to improve the integration of the test tooling, reduce the volume of the test tooling, and be applicable to battery fixture tests of various specifications.

[0076] According to some embodiments of the present application, two test assemblies are provided, the two test assemblies are provided in a one-to-one correspondence with the two covering members 200 , and the two test assemblies are provided along a first direction.

[0077] Optionally, the detection elements 301 of the two test assemblies are arranged in the same manner so that the parameters to be measured on the two clamping surfaces can be compared with each other.

[0078] Optionally, the detection elements 301 of the two test assemblies are arranged in an alternating manner, and the two test assemblies can complement each other. By moving the base 100, the two test assemblies can respectively detect the same clamping surface to achieve more comprehensive collection point detection on one clamping surface.

[0079] As a result, the two test components can simultaneously obtain the parameters to be measured on the two clamping surfaces, and conveniently and quickly realize the characterization of the consistency of clamping stress at different collection points.

[0080] According to some embodiments of the present application, the test assembly includes a plurality of detection elements 301 .

[0081] Optionally, multiple detection elements 301 are symmetrically distributed along the midline of the covering member 200 along the second direction. Referring to the figure, the second direction is perpendicular to the first direction. Exemplarily, the second direction is the length direction of the clamping surface of the battery clamp. Thus, the symmetrically distributed multiple detection elements 301 can be used as references to each other, thereby quickly determining the flatness of the clamping surface.

[0082] Thus, the multiple detection elements 301 can simultaneously obtain the parameters to be measured at multiple collection points, so as to improve the accuracy of characterizing the flatness through the parameters to be measured, thereby improving the detection accuracy of the test fixture.

[0083] According to some embodiments of the present application, the base 100 is provided with a first fixing structure, and the detection element 301 is detachably mounted on the first fixing structure.

[0084] Optionally, the number of the first fixed structures is greater than the number of the detection elements 301 , so that the detection elements 301 can switch between different first fixed structures to acquire parameters to be measured at different acquisition points on the clamping surface.

[0085] Optionally, the detection element 301 is connected and fixed to the first fixing structure by snap connection, threaded connection, magnetic connection or other forms that are easy to disassemble.

[0086] Therefore, the first fixed structure can be used to adjust the position of the detection element 301 to achieve detection of different collection points on the clamping surface, so that the test fixture can improve the authenticity of the fitting plane through multiple detections, thereby improving the measurement accuracy of flatness.

[0087] According to some embodiments of the present application, the base 100 is provided with a second fixed structure, the second fixed structure is movably disposed on the base 100 at least along the second direction, and the detection element 301 is installed on the second fixed structure.

[0088] Optionally, the second fixing structure is movable along a third direction, which is perpendicular to the second direction, and the second fixing structure drives the detection element 301 to contact different positions of the covering member 200 to realize detection of different collection points of the clamping surface.

[0089] Thus, the detection element 301 can move in the base 100 through the second fixed structure to detect different acquisition points on the clamping surface, and obtain more parameters to be measured to improve the measurement accuracy of the flatness of the clamping surface.

[0090] According to some embodiments of the present application, the plurality of detection elements 301 are symmetrically distributed along a midline of the covering member 200 along a third direction, and the third direction is perpendicular to the first direction and the second direction.

[0091] Thus, the plurality of detection elements 301 are distributed in a centrally symmetrical manner, wherein any four detection elements 301 distributed in a rectangular shape can serve as references to each other to quickly determine the flatness of the corresponding four acquisition points, thereby improving the detection efficiency of the test fixture.

[0092] According to some embodiments of the present application, the battery fixture test tool further includes a power supply component 410, which is electrically connected to the test component, and the power supply component 410 is used to provide electrical energy to the test component.

[0093] Optionally, the energy supply unit 410 includes a power supply, and the power supply is a rechargeable power supply or a disposable power supply. Exemplarily, the power supply is detachably mounted on the base 100, and the power supply is arranged in the middle of the base 100 along the first direction to shorten the wiring distance between the power supply and the two test components and reduce the volume of the battery fixture test tooling.

[0094] Optionally, the energy supply component 410 uses a power cord, and the test component is connected to electricity through the power cord for use.

[0095] Therefore, the battery clamp test fixture can ensure the normal operation of the detection element 301 through the energy supply component 410 to complete the flatness test of the clamping surface.

[0096] According to some embodiments of the present application, the battery fixture test tool further includes a wireless transmission component 420, which is communicatively connected to the test component, and the wireless transmission component 420 is used to wirelessly transmit and output the parameters to be tested.

[0097] Thus, the wireless transmission component 420 can transmit the measured data to other smart terminals to complete further calculation or fitting operations.

[0098] According to some embodiments of the present application, the battery fixture testing tool further includes a junction box 430 , which is disposed in the base 100 and is used to organize circuit cables and signal cables inside the base 100 .

[0099] Optionally, the junction box 430 is made of insulating material to improve the insulation safety performance of the battery fixture test tooling.

[0100] This facilitates the normal operation of the internal components of the battery fixture test tooling and organizes the internal cables to reduce the difficulty of subsequent maintenance.

[0101] In a second aspect, an embodiment of the present application provides a battery production system, including a battery fixture and a battery fixture testing tool provided by any embodiment of the first aspect. By introducing the battery fixture testing tool, the battery production system can regularly detect the flatness of the clamping surface of the battery fixture to improve the product yield of the glue pressing process during the battery module assembly process.

[0102] According to some embodiments of the present application, the battery production system further includes a moving mechanism, and the base 100 of the battery fixture testing tool is installed at the output end of the moving mechanism, and the moving mechanism drives the battery fixture testing tool to move into the battery fixture to complete the inspection.

[0103] Optionally, the battery production system is detachably connected to the moving mechanism.

[0104] See also Figure 1 and Figure 2The embodiment of the present application provides a battery fixture test tool, including a base 100, two covering members 200 and two test components. The two covering members 200 are arranged on both sides of the base 100 along a first direction to fit the two clamping surfaces of the battery fixture. The two test components are detachably installed in the base 100 and are arranged in contact with the two sides of the covering members 200 facing away from the battery fixture in a one-to-one correspondence. Among them, the test component includes multiple pressure sensors. The battery fixture test tool measures the clamping pressure of multiple collection points on the clamping surface and realizes the characterization of the flatness of the clamping surface through the uniformity between the multiple clamping pressures, and then repairs and maintains the battery fixture based on this, improving the processing quality of the glue pressing process and the product yield.
