Description

Technical Field

[0001] The utility model belongs to the technical field of new energy battery cold plates, and relates to a novel battery cold plate insulation withstanding voltage test tooling. Background Art

[0002] In today's battery technology field, the insulation withstanding voltage performance of battery cold plates is crucial. With the continuous development of battery technology, the quality requirements for battery cold plates are also increasing day by day.

[0003] The traditional battery cold plate insulation withstanding voltage test method mainly uses a multimeter for testing. During the test, employees use test leads to select individual points on the product surface for testing. This test method has many drawbacks.

[0004] First of all, the test is not comprehensive enough. Since only individual points are selected for testing, the entire surface of the battery cold plate cannot be covered, and some areas with potential problems may be missed. This greatly reduces the accuracy of the test results and cannot truly reflect the insulation withstanding voltage performance of the battery cold plate.

[0005] Secondly, it is easy to damage the surface insulation layer of the product. When the test lead contacts the product surface, the insulation layer may be damaged due to improper operation or other reasons, resulting in defective products. Once defective products occur, rework is required, which not only wastes a lot of manpower but also increases the production manufacturing cost.

[0006] Moreover, employees need to spend a lot of time when using the traditional test method. Because each point needs to be tested one by one, the operation is cumbersome and the efficiency is low. This undoubtedly increases the labor cost and also affects the production progress.

[0007] In addition, the traditional test method also has certain potential safety hazards. During the test, employees may come into contact with high voltage electricity. If the operation is improper, safety accidents may occur, threatening the lives and safety of employees.

[0040] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0041] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0042] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are generally in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions of the components themselves; similarly, for ease of understanding and description, "inner, outer" refer to the inner and outer of the contours of the components themselves, but the above orientation words do not limit the present utility model. Embodiment

[0043] See Figures 1 - 6 As shown, a new type of battery cold plate insulation withstand voltage test tooling includes an insulating carrier plate 2 for placing product 1. The insulating carrier plate 2 is made of high-performance insulating material, which can effectively prevent current leakage and ensure the accuracy of the test. At its edge, there is a jaw cylinder assembly 3 in contact with product 1. The jaw cylinder assembly 3 adopts advanced pneumatic control technology and can stably clamp product 1 to ensure that product 1 does not displace during the test.

[0044] Above the insulating carrier plate 2, there is an insulating bearing plate 4 that can move vertically. The insulating bearing plate 4 is also made of high-quality insulating material and plays a key supporting and conductive connection role during the test. At the lower end of the insulating bearing plate 4, there is a pressing plate 5 fixedly installed. At the lower end of the pressing plate 5, there is a conductive rubber layer 6 that can be pressed on product 1. The conductive rubber layer has good conductivity and flexibility and can closely cover the entire surface of the product to ensure the comprehensiveness and accuracy of the test.

[0045] The pressing plate 5 and the jaw cylinder assembly 3 are respectively conductively connected to a withstand voltage test instrument (the withstand voltage test instrument is not shown in the figure). During the test, the insulating bearing plate 4 descends vertically, so that the conductive rubber layer 6 on the pressing plate 5 is pressed on the product surface. The conductive rubber layer 6 has good conductivity and flexibility and can evenly distribute voltage when contacting product 1 to ensure that every part of the product surface can receive the action of the test voltage.

[0046] One set of wires of the withstand voltage test instrument is connected to the pressing plate 5 to supply power to the pressing plate 5. After the current flows into the pressing plate 5 through the wires, due to the good conductivity of the conductive rubber layer 6, the voltage quickly acts on the surface of product 1. At the same time, the other set of wires of the withstand voltage test instrument is connected to the jaw cylinder assembly 3. After the voltage acts on the product surface, the voltage on product 1 flows back to the withstand voltage test instrument through the jaw cylinder assembly 3. In this way, a complete test circuit is formed.

[0047] The design of this test circuit has many advantages. On the one hand, it realizes a comprehensive test of the entire surface of the product. Traditional test methods often can only test individual points of the product and cannot cover the entire surface, which is likely to lead to inaccurate test results. With this new test tooling, the conductive rubber layer can be closely pressed on the product surface to ensure that every part of the product can receive the action of the test voltage, greatly improving the accuracy of the test. On the other hand, this test method avoids damaging the insulating film on the product surface. The traditional pen test method is likely to damage the insulating film during the test, thus affecting the quality of the product. The soft characteristic of the conductive rubber layer makes it not damage the insulating film when contacting the product, ensuring the quality of the product.

[0048] Furthermore, several insulating connection plates 7 are provided at the edges of the insulating carrier plate 4 and the pressing plate 5. These insulating connection plates 7 play an important role in connection and fixation. The insulating connection plates 7 are tightly and fixedly connected to the insulating carrier plate 4 and the pressing plate 5 by screws. Specifically, the above-mentioned insulating connection plates 7 have carefully designed notches. During installation, the edges of the insulating carrier plate 4 and the pressing plate 5 are simultaneously clamped in the notches, so that the positions of the three are accurately aligned. Subsequently, screws are used to firmly lock the insulating carrier plate 4, the pressing plate 5 and the insulating connection plates 7 together. Such a design ensures the stability and reliability of the insulating carrier plate 4 and the pressing plate 5 during the test process. The existence of the insulating connection plates 7 not only enhances the strength of the overall structure, but also effectively prevents current leakage in unnecessary places, ensuring the accuracy and safety of the test.

[0049] In this embodiment, a profiling groove for placing the product 1 is provided on the insulating carrier plate 2. The shape of the profiling groove perfectly fits the outer shape of the product, which can ensure that the product 1 is stably placed on the insulating carrier plate 2 and will not shake or displace during the test process. A notch 21 communicating with the profiling groove is also provided on the insulating carrier plate 2. A jaw cylinder assembly 3 is provided at the notch 21. The jaw cylinder assembly 3 can pass through the notch 21 and be clamped and connected to the product 1 in the profiling groove.

[0050] Preferably, the conductive rubber layer 6 is composed of flexible conductive rubber. This flexible conductive rubber has good conductivity and flexibility, can be tightly pressed on the product surface, ensuring the comprehensiveness and accuracy of the test. At the same time, its soft characteristics also avoid damaging the insulating film on the product surface, providing a strong guarantee for the quality of the product.

[0051] In this embodiment, a lifting mechanism 8 with double-layer downward pressure is provided on the periphery of the insulating carrier plate 4. This lifting mechanism 8 plays a crucial role in the entire test tooling, providing stable and precise power for the vertical movement of the insulating carrier plate 4.

[0052] As Figure 3 shown, the lifting mechanism 8 includes a fixed carrier plate 801 and a movable carrier plate 802 located below it. Guide sleeves are provided at the corners of the movable carrier plate 802, and vertical guide rods 803 are provided inside the guide sleeves. The upper ends of the vertical guide rods 803 are firmly fixed to the fixed carrier plate 801, and the lower ends are provided with floor feet. These vertical guide rods 803 provide stable guidance for the up and down movement of the movable carrier plate 802, ensuring that it will not shift or shake during the movement process.

[0053] A fixed base plate 801 is provided with a fixed seat 804, and a servo motor 805 is installed on the fixed seat 804. The servo motor 805 serves as the main power source of the lifting mechanism 8 and is connected to one end of the lead screw through a coupling 806. A lead screw nut 807 on the lead screw is fixed to the fixed seat 804 through an adapter 808 to ensure the stability of the lead screw during rotation. The lead screw nut 809 on the lead screw is connected to a fixed sleeve 810. When the servo motor 805 drives the lead screw to rotate, the lead screw nut 809 moves up and down along the lead screw, thereby driving the fixed sleeve 810 to move together. The lower end of the fixed sleeve 810 is fixedly connected to the movable base plate 802. In this way, the rotation of the servo motor 805 is converted into the up and down movement of the movable base plate 802.

[0054] On the movable base plate 802 where the outer periphery of the fixed sleeve 810 is located, a driving cylinder 811 is provided. The number of the driving cylinders 811 is four, and they are distributed in a matrix on the movable base plate 802. The piston of the driving cylinder 811 is fixedly connected to the insulating carrier plate 4. When the movable base plate 802 moves to a certain position under the action of the servo motor 805 and the lead screw, the driving cylinder 811 starts to work, further pushing the insulating carrier plate 4 downward to tightly press the conductive rubber layer 6 on the pressing plate 5 against the surface of the product 1. This double-layer downward pressing design not only ensures the accuracy and stability of the movement of the insulating carrier plate 4 but also can provide sufficient pressure to ensure good contact between the conductive rubber layer 6 and the surface of the product 1, thereby realizing accurate testing of the product.

[0055] Furthermore, a distance measuring sensor 812 for measuring the moving distance of the insulating carrier plate 4 is provided on the fixed base plate 801. The presence of this distance measuring sensor 812 plays a key role in the precise operation of the entire testing tooling. Avoidance grooves for the light of the distance measuring sensor 812 to pass through are provided on both the fixed base plate 801 and the movable base plate 802. Such a design ensures that the distance measuring sensor 812 can work normally without being interfered by the structure of the base plate. When the insulating carrier plate 4 moves vertically under the action of the lifting mechanism, the distance measuring sensor 812 can monitor its moving distance in real time. By accurately monitoring the vertical moving distance of the insulating carrier plate 4, the contact pressure between the pressing plate 5 and the product surface during the testing process can be better controlled to ensure the accuracy and stability of the testing. At the same time, it can also timely detect possible failures or abnormal conditions of the lifting mechanism, providing a strong guarantee for the safe operation of the testing tooling.

[0056] In this embodiment, a moving mechanism 9 is provided below the insulating base plate 2. This moving mechanism 9 brings higher flexibility and convenience to the entire testing tooling.

[0057] The moving mechanism 9 is equipped with a moving carrier plate 901 that can move horizontally in a straight line. This moving carrier plate 901 is the core component of the entire moving mechanism. It bears the weight of the insulating carrier plate 2 and the products 1 placed on the insulating carrier plate 2, and can achieve smooth horizontal linear motion under specific driving. The moving carrier plate 901 is fixedly connected to the insulating carrier plate 2 through a plurality of pads by bolts. These pads play a role in supporting and buffering, ensuring that the insulating carrier plate 2 remains stable during movement and does not shake or tilt.

[0058] As Figure 4 shown, the moving mechanism 9 includes a horizontal lead screw assembly 903 and a linear slide rail 904 driven by a servo motor 902. The servo motor 902 serves as the power source and provides precise driving force for the horizontal lead screw assembly 903. The horizontal lead screw assembly 903 consists of components such as a lead screw and a lead screw nut, which can be directly purchased from the market and belong to the prior art. When the servo motor 902 drives the lead screw to rotate, the lead screw nut moves horizontally in a straight line along the lead screw, thereby driving the connected moving carrier plate 901 to move together. The linear slide rail 904 provides additional guidance and support for the movement of the moving carrier plate 901. The linear slider on the linear slide rail 904 is fixedly connected to the moving carrier plate 901 to ensure the smoothness and accuracy of the moving carrier plate 901 during horizontal linear motion.

[0059] The horizontal lead screw assembly and the linear slide rail are distributed in parallel. This design makes the force on the moving carrier plate 901 more uniform during movement and the movement more stable. The lead screw slider on the horizontal lead screw assembly and the linear slider on the linear slide rail are both fixedly connected to the moving carrier plate. Through the synergistic effect of the two, the precise horizontal linear motion of the moving carrier plate is achieved. Such a design enables the product to be quickly and accurately moved to a specific position according to needs during the test, improving the test efficiency and the convenience of operation.

[0060] As Figure 5 shown, the moving carrier plate 901 is fixedly connected to the jaw cylinder assembly 3. Specifically, the jaw cylinder assembly 3 includes a jaw carrier plate 301 fixed on the moving carrier plate 901. This jaw carrier plate 301 serves as the installation base of the jaw cylinder assembly and plays a role in stable support. It is firmly connected and fixed to the moving carrier plate 901 by bolts to ensure that the jaw cylinder assembly 3 can always maintain a stable working state during the movement of the moving carrier plate.

[0061] The jaw carrier plate 301 is provided with first cylinders 302 distributed left and right. The first cylinders 302 are used to adjust the clamping position. The piston of the first cylinder 302 is fixedly connected to the connecting carrier plate 303. The connecting carrier plate 303 plays a role in connecting and transmitting power in the entire jaw cylinder assembly.

[0062] On the connecting carrier plate 303, there are clamping jaw cylinders 304 distributed front and back. The clamping jaw cylinder 304 is the core component of the clamping jaw cylinder assembly and is responsible for clamping the product. During use, the clamping jaw part of the clamping jaw cylinder 304 tightly clamps the product placed on the insulating carrier plate. After the test is completed, the clamping jaw cylinder will release the clamping jaw to release the product for the test operation of the next product.

[0063] In this embodiment, the clamping jaw of the clamping jaw cylinder 304 is responsible for grasping one side of the product 1. During the test, this clamping jaw plays a crucial role. The clamping jaw is connected to the withstand voltage test instrument through a wire to ensure the transmission of the test signal. When the clamping jaw cylinder 304 works, the clamping jaw tightly holds the product, and at the same time transmits the test signal of the product to the withstand voltage test instrument through the wire for analysis and judgment.

[0064] The above-mentioned wire passes through the spacer block and is limited by the spacer block. The spacer block plays an important role in this process. On the one hand, the spacer block provides a passage for the wire to pass through, enabling the wire to be smoothly connected to the clamping jaw and the withstand voltage test instrument. On the other hand, the spacer block plays a role in limiting the wire, standardizing the routing of the wire. This can avoid the wire being in a mess during the test, prevent the wire from being damaged due to entanglement or pulling, and ensure the stability and reliability of the test system. At the same time, the standardized routing also makes the entire test tooling cleaner and more beautiful, facilitating maintenance and management.

[0065] The novel battery cold plate insulation withstand voltage test tooling of the present utility model is an integral part of the entire production line, and is connected to the control unit, power supply unit, and air supply unit on the production line for unified control to achieve automated testing.

[0066] In summary, the present utility model can achieve testing that can cover the entire surface end of the product. Compared with the traditional testing method that can only detect local points, this comprehensive testing method enables the obtained data to be more comprehensive. The comprehensive data can more accurately reflect the insulation withstand voltage performance of the product, making the test results more accurate and reliable. At the same time, the test tooling integrates flexible conductive rubber, and when testing, the flexible conductive rubber contacts the end face of the product. The flexible conductive rubber has good flexibility and conductivity. On the one hand, it can ensure full contact with the end face of the product to ensure the accuracy of the test; on the other hand, due to its soft characteristics, it also avoids damage to the surface insulation film of the product, effectively guaranteeing the quality of the product. At the same time, the automated testing process not only improves production efficiency, reduces the time and error of manual operation, but also makes the employee operation simpler and faster. Eliminating the potential safety hazards in the traditional testing method, the working environment of employees is safer.
