Description

Technical Field

[0001] The utility model relates to the technical field of battery testing equipment, in particular to a tray, a testing device and a testing system. Background Art

[0002] During the research and development of batteries, battery cells need to be tested, and they can only be put into production after passing various performance tests. Therefore, the testing process of battery cells is particularly important in the entire battery production process. When testing battery cells, it is necessary to use a tray to carry the battery cells to be tested, and place the tray together with the battery cells on a carrying mechanism so that the battery cells to be tested can be electrically connected to the external testing device through the tray. In related technologies, in order to test multiple parameters of battery cells, the tray is provided with multiple conductive terminals. However, due to the different required parameters, the sizes of the conductive terminals are also different, making it difficult to install multiple conductive terminals on the same part. Utility Model Content

[0003] In view of the above problems, the present invention provides a tray, a testing device and a testing system, which at least solve the technical problem that multiple conductive terminals of the tray are difficult to install on the same part.

[0004] In the first aspect, the utility model provides a tray, which includes a tray body and a power connection mechanism, wherein the tray body is used to carry battery cells; the power connection mechanism includes a support frame and multiple pairs of conductive terminals, the multiple pairs of conductive terminals are arranged on the support frame, and the support frame is installed on the tray body, and the multiple pairs of conductive terminals are used to electrically connect with the battery cells, the support frame includes a main body and a connecting piece, the connecting piece is detachably connected to the main body, and the conductive terminals include a first terminal and a second terminal both arranged in pairs, the first terminal is arranged on the main body, and the second terminal is arranged on the connecting piece, and the size of the first terminal is different from the size of the second terminal.

[0005] In the tray of this embodiment of the utility model, when the tray body carries a battery cell, multiple pairs of conductive terminals can be electrically connected to the battery cell. This allows external testing equipment outside the tray to collect multiple parameters of the battery cell through the multiple pairs of conductive terminals, thereby simultaneously testing multiple parameters of the battery cell, thereby improving battery cell testing efficiency. In addition, the first and second terminals of different sizes are respectively arranged on the main body and connecting piece of the support frame, and the main body and connecting piece are detachably connected, making the first and second terminals easier to install.

[0006] In certain embodiments, the thickness of the body is greater than the thickness of the connecting piece, the length of the first terminal is greater than the length of the second terminal, the first terminal is disposed along its length through the body, and the second terminal is disposed along its length through the connecting piece. Thus, the longer first terminal, when mounted on the thicker body, allows for a stable installation; the shorter second terminal, when mounted on the thinner connecting piece, allows for a stable installation.

[0007] In some embodiments, the cross-sectional area of ​​the first terminal is larger than the cross-sectional area of ​​the second terminal. Thus, the first terminal and the second terminal have different current conducting capacities, so that multiple pairs of conductive terminals can meet different parameter testing requirements.

[0008] In some embodiments, multiple pairs of conductive terminals are arranged in the same direction. This simplifies the arrangement of the multiple pairs of conductive terminals, making the power connection mechanism easier to manufacture and reducing the manufacturing cost of the tray. Furthermore, arranging the multiple pairs of conductive terminals in the same direction also makes it easier to connect the conductive terminals and connect them to the battery cells.

[0009] In certain embodiments, the support frame is connected to the side of the tray, the top surface of the tray is configured to support the battery cells, and multiple pairs of conductive terminals are located on the side of the tray facing the top surface. Thus, the support frame is connected to the side of the tray, which reduces the space occupied by the support frame on the top surface of the tray, allowing more space on the top surface of the tray to support the battery cells, thereby miniaturizing the tray. Furthermore, multiple pairs of conductive terminals are located on the side of the tray facing the top surface, which facilitates connection between the conductive terminals and the battery cells.

[0010] In some embodiments, the tray further includes a stopper disposed on the top surface, the stopper being used to stop the battery cells. In this way, the stopper can reduce the movement of the battery cells and reduce the risk of poor contact between the battery cells and the conductive terminals.

[0011] In some embodiments, the tray includes a wire, one end of which is connected to the conductive terminal and the other end of which is used to connect to the battery cell or sensor. In this way, the conductive terminal is connected to the battery cell through the wire, making the electrical connection between the conductive terminal and the battery cell more stable.

[0012] In a second aspect, the testing device according to an embodiment of the present invention includes a carrying mechanism and the above-mentioned tray, wherein the tray is arranged on the carrying mechanism.

[0013] In certain embodiments, the testing device further includes an electrical adapter mechanism comprising multiple pairs of conductive probes configured to abut the conductive terminals. Thus, the testing device, through the abutment of the conductive probes of the electrical adapter mechanism with the conductive terminals, enables the battery cells to be electrically connected to external testing equipment via the conductive terminals and the conductive probes, facilitating smooth testing of the battery cells.

[0014] In certain embodiments, the support mechanism includes a support plate and a bracket mounted on the support plate, the tray mounted on the bracket, and multiple brackets arranged in intervals, with each bracket being provided with a tray. In this manner, the support plate provides support for the bracket, which in turn supports the tray, thereby stabilizing the position of the tray. Multiple brackets and trays, when combined, enable simultaneous testing of multiple battery cells, improving battery cell testing efficiency.

[0015] In a third aspect, the present invention provides a testing system, which includes the testing device in the above embodiment.

[0016] The above description is only an overview of the technical solution of the present invention.

[0031] In the description of the embodiments of the present invention, "top" refers to the side of the component facing horizontally upward when the battery or battery cell is in normal use.

[0032] During the battery R&D process, battery cells need to be tested. For example, parameters such as current, voltage, and resistance need to be tested. Only after all performance tests are passed can they be put into production. When testing battery cells, a tray is used to support the battery cells to be tested. The tray and the battery cells are placed on a supporting mechanism to establish an electrical connection between the battery cells to be tested and external testing equipment.

[0033] In the related art, during battery cell testing, a tray and battery cells are placed on a supporting structure. An external testing device then connects to the battery cell terminals via a pair of wires to collect battery cell parameters for testing. However, to test multiple battery cell parameters, the tray is equipped with multiple conductive terminals. However, due to the different required parameters, the conductive terminals have different sizes, making it difficult to install multiple conductive terminals on the same part.

[0034] To address the technical issue of high test frequency and low efficiency when testing multiple parameters of battery cells, the present invention provides a power connection mechanism on the tray body. The power connection mechanism includes multiple pairs of conductive terminals. When the tray body carries the battery cells, the multiple pairs of conductive terminals can be electrically connected to the battery cells. This allows external testing equipment outside the tray to collect multiple parameters of the battery cells through the multiple pairs of conductive terminals, thereby simultaneously testing multiple parameters of the battery cells and improving battery testing efficiency. In addition, first and second terminals of different sizes are respectively disposed on the support frame body and connecting piece, and the body and connecting piece are detachably connected, making the first and second terminals easier to install.

[0035] It should be pointed out that the battery cell testing process referred to in the present invention refers to the entire process from the time the battery cell is placed on the tray to the time the external testing equipment completes the testing of the battery cell.

[0036] See also Figure 1 and Figure 2 The testing device 1000 of the embodiment of the present invention includes a tray 100 and a supporting mechanism 200, wherein the tray 100 is disposed on the supporting mechanism 200. Specifically, the tray 100 is used to place battery cells 1100. For example, the battery cells 1100 can be fixed to the tray 100 by fixing elements such as straps, so that the position of the tray 100 relative to the tray 100 remains stable. The supporting mechanism 200 can support the tray 100, so that the position of the tray 100 is stable, and thus the position of the battery cells 1100 remains stable, which is conducive to smooth testing of the battery cells 1100.

[0037] In one example, the battery cells 1100 may be first fixed on the tray 100 and then transferred to the supporting mechanism 200 along with the tray 100 , so that parameters of the battery cells 1100 can be collected and tested.

[0038] See also Figure 3 and Figure 4The tray 100 of the embodiment of the present invention includes a tray body 10 and a power connection mechanism 20. The tray body 10 is used to carry battery cells 1100; the power connection mechanism 20 includes a support frame 21 and multiple pairs of conductive terminals 22. The multiple pairs of conductive terminals 22 are arranged on the support frame 21. The support frame 21 is installed on the tray body 10. The multiple pairs of conductive terminals 22 are used to electrically connect with the battery cells 1100. The support frame 21 includes a main body 211 and a connecting piece 212. The connecting piece 212 is detachably connected to the main body 211. The conductive terminals 22 include a first terminal 221 and a second terminal 222, both of which are arranged in pairs. The first terminal 221 is arranged on the main body 211, and the second terminal 222 is arranged on the connecting piece 212. The size of the first terminal 221 is different from that of the second terminal 222.

[0039] Specifically, the tray 10 is a supporting member that provides support for the battery cells 1100. The tray 10 can be made of metal materials such as stainless steel and aluminum alloy, or plastic. The power connection mechanism 20 serves as an intermediary for achieving electrical connection between the battery cells 1100 and external testing equipment. In other words, external testing equipment can achieve electrical connection with the battery cells 1100 through the power connection mechanism 20.

[0040] The support frame 21 provides support for the multiple pairs of conductive terminals 22, ensuring that the positions of the multiple pairs of conductive terminals 22 remain stable. It will be appreciated that the conductive terminals 22 are conductive elements. Therefore, to reduce the risk of short circuits between the multiple pairs of conductive terminals 22, the support frame 21 is generally made of an insulating material. For example, the support frame 21 may be made of plastic. The support frame 21 may be secured to the tray body 10 by screws, adhesive bonding, welding, or other methods.

[0041] The main body 211 is in the shape of a sheet as a whole, and may be an irregular shape so that the main body 211 can adapt to the shape of the tray 10. The connecting piece 212 can be mounted on the main body 211 by screws.

[0042] The conductive terminal 22 is a conductive member in a sheet, block, or columnar shape. It can be made of a conductive material such as copper. The conductive terminal 22 can be electrically connected to the battery cell 1100's terminal post 1110, the battery housing, and other components. The conductive terminal 22 can be embedded in the support frame 21, with one side of the conductive terminal 22 exposed outside the support frame 21 to facilitate electrical connection.

[0043] It will be appreciated that a pair of conductive terminals 22 includes two conductive terminals 22. Therefore, in the embodiment of the present invention, the number of conductive terminals 22 is at least four. The pair of conductive terminals 22 forms a loop for the acquisition circuit of the battery cell 1100, thereby facilitating the acquisition of parameters of the battery cell 1100. The parameters of the battery cell 1100 include, but are not limited to, temperature, voltage, resistance, and current.

[0044] The dimensions of the first terminal 221 and the second terminal 222 may be length, width or cross-sectional area, or in other words, the length of the first terminal 221 may be greater than the length of the second terminal 222; the width of the first terminal 221 may be greater than the width of the second terminal 222; the cross-sectional area of ​​the first terminal 221 may be greater than the cross-sectional area of ​​the second terminal 222.

[0045] Therefore, in the tray 100 of the embodiment of the present invention, when the tray body 10 carries the battery cells 1100, multiple pairs of conductive terminals 22 can be electrically connected to the battery cells 1100, allowing external testing equipment outside the tray 100 to collect multiple parameters of the battery cells 1100 through the multiple pairs of conductive terminals 22, thereby simultaneously testing multiple parameters of the battery cells 1100 and improving the testing efficiency of the battery cells 1100. In addition, the first terminals 221 and the second terminals 222 of different sizes are respectively disposed on the main body 211 and the connecting piece 212 of the support frame 21, and the main body 211 and the connecting piece 212 are detachably connected, making the first terminals 211 and the second terminals 222 easier to install.

[0046] like Figure 3 and Figure 4 As shown, in some embodiments, the tray body 10 includes a bottom plate 11 and support bars 12, which are connected to the bottom edge of the bottom plate 11. The support bars 12 are provided on two opposite edges of the bottom plate 11, so that the tray 100 can be more stably placed on the supporting mechanism 200 via the support bars 12. The bottom plate 11 is used to support the battery cells 1100, or in other words, the battery cells 1100 are placed on the bottom plate 11.

[0047] In some embodiments, multiple pairs of conductive terminals 22 are arranged in the same direction. In other words, the centers of all conductive terminals 22 are arranged on the same virtual straight line. This simplifies the arrangement of multiple pairs of conductive terminals 22, making the power connection mechanism 20 easier to manufacture and reducing the manufacturing cost of the tray 100. Furthermore, arranging multiple pairs of conductive terminals 22 in the same direction also makes it easier to connect the conductive terminals 22 to the battery cells 1100.

[0048] In some embodiments, at least two pairs of conductive terminals 22 have different flow areas. Specifically, the flow areas of the conductive terminals 22 may be the cross-sectional areas of the conductive terminals 22. It is understood that the larger the flow area of ​​the conductive terminals 22, the greater the flow conductivity of the conductive terminals 22.

[0049] For example, when testing the current of a battery cell 1100, the output current of the battery cell 1100 may be relatively high, thus requiring a conductive terminal 22 with a larger flow area. When testing the temperature of the battery cell 1100, the current generated by the sensor is relatively small, so a conductive terminal 22 with a smaller flow area can be used. Thus, conductive terminals 22 with different cross-sectional areas have different flow capacities, allowing multiple pairs of conductive terminals 22 to meet different parameter testing requirements.

[0050] In some embodiments, the cross-sectional area of ​​the first terminal 211 is larger than the cross-sectional area of ​​the second terminal 222. Thus, the first terminal 211 and the second terminal 222 have different current conducting capacities, so that multiple pairs of conductive terminals 21 can meet different parameter testing requirements.

[0051] In some embodiments, the thickness of the body 211 is greater than the thickness of the connecting piece 212, and the length of the first terminal 221 is greater than the length of the second terminal 222. The first terminal 221 is disposed along its length through the body 211, and the second terminal 222 is disposed along its length through the connecting piece 212. Thus, the first terminal 221 is longer and can be mounted on the thicker body 211, allowing the first terminal 221 to be mounted stably. Furthermore, the second terminal 222 is shorter and can be mounted on the thinner connecting piece 212, allowing the second terminal 222 to be mounted stably.

[0052] In some embodiments, the support frame 21 is connected to the side surface 13 of the tray 10 , the top surface 14 of the tray 10 is configured to support the battery cells 1100 , and the multiple pairs of conductive terminals 22 are located on the side facing the top surface 14 of the tray 10 .

[0053] Specifically, the upper surface of the bottom plate 11 of the tray body 10 forms the top surface 14 of the tray body 10, while the bottom plate 11 and the support bars 12 together form the side surfaces 13 of the tray body 10. The main body 211 of the support frame 21 is disposed on the side surfaces 13 of the tray body 10. Multiple pairs of conductive terminals 22 are located on the side of the tray body 10 facing the top surface 14. In other words, all conductive terminals 22 are located above the top surface 14 of the tray body 10.

[0054] During testing, the battery cell 1100 is placed on the top surface 14 of the tray 10, with the bottom of the battery cell 1100 in contact with the top surface 14 of the tray 10, and the terminal 1110 of the battery cell 1100 is located on top of the battery cell 1100. Placing all of the conductive terminals 22 above the top surface 14 of the tray 10 facilitates connection between the conductive terminals 22 and the terminal 1110 of the battery cell 1100.

[0055] Therefore, the support frame 21 is connected to the side surface 13 of the tray body 10, which reduces the space occupied by the support frame 21 on the top surface 14 of the tray body 10, leaving more space on the top surface 14 of the tray body 10 to support the battery cells 1100, thereby miniaturizing the tray body 10. In addition, multiple pairs of conductive terminals 22 are located on the side facing the top surface 14 of the tray body 10, which facilitates the connection between the conductive terminals 22 and the battery cells 1100.

[0056] See also Figure 3 and Figure 4 In some embodiments, the tray 100 further includes a stopper 30 disposed on the top surface 14 of the tray body 10. The stopper 30 is used to limit the position of the battery cell 1100. Specifically, the stopper 30 can be made of a material with high rigidity so that the stopper 30 deforms less after contact with the battery cell 1100, thereby limiting the position of the battery cell 1100. The stopper 30 can contact the side surface 13 of the battery cell 1100, thereby limiting the position of the battery cell 1100.

[0057] During the testing process of the battery cell 1100, the position of the battery cell 1100 needs to remain stable so that the battery cell 1100 remains electrically connected to the external testing equipment. Therefore, the limit member 30 can reduce the position movement of the battery cell 1100 and reduce the risk of poor contact between the battery cell 1100 and the conductive terminal 22.

[0058] In some embodiments, the limiting member 30 includes a first limiting plate 31 and a second limiting plate 32 intersecting the first limiting plate 31 . The first limiting plate 31 , the second limiting plate 32 and the top surface 14 of the disk body 10 together form a storage space for accommodating the battery cell 1100 .

[0059] Specifically, the first limiting plate 31 and the second limiting plate 32 intersect to adapt to the shape of the battery cell 1100. The first limiting plate 31 and the second limiting plate 32 work together to give the limiting member 30 a bent shape. For example, the first limiting plate 31 can be perpendicular to the second limiting plate 32, and the heights of the first limiting plate 31 and the second limiting plate 32 can be perpendicular to the top surface 14 of the tray 10. The first limiting plate 31 can contact the first outer wall of the battery cell 1100, the second limiting plate 32 can contact the second outer wall of the battery cell 1100, and the top surface 14 of the tray 10 can contact the bottom surface of the battery cell 1100. The first limiting plate 31, the second limiting plate 32, and the top surface 14 of the tray 10 work together to limit the freedom of the battery cell 1100 in three directions, so that the position of the battery cell 1100 remains stable.

[0060] In this way, the first limiting plate 31, the second limiting plate 32, and the top surface 14 of the tray body 10 can respectively limit the degrees of freedom of the battery cell 1100 in different directions, thereby limiting the position of the battery cell 1100. In addition, the first limiting plate 31 and the second limiting plate 32 can also position the battery cell 1100 when it is placed on the top surface 14 of the tray body 10, which helps to accurately place the battery cell 1100 on the top surface 14 of the tray body 10.

[0061] It should be noted that after the battery cell 1100 is placed on the top surface 14 of the tray 10 , the battery cell 1100 can be further fixed using fixing elements such as straps.

[0062] See also Figure 3 and Figure 4 In some embodiments, the first limiting plate 31 and / or the second limiting plate 32 are formed with through holes 33, which extend through both sides of the first limiting plate 31 and / or the second limiting plate 32 in the thickness direction. In other words, in some embodiments, the first limiting plate 31 is formed with a through hole 33. In some embodiments, the second limiting plate 32 is formed with a through hole 33. In some embodiments, both the first limiting plate 31 and the second limiting plate 32 are formed with a through hole 33.

[0063] The through hole 33 can be a circular hole, a square hole, or other shapes. The number of through holes 33 can be one, two, or more. In this way, the through hole 33 not only reduces the weight of the retaining member 30, but also reduces the contact area between the battery cell 1100 and the retaining member 30, thereby improving the heat dissipation efficiency of the battery cell 1100 during testing, reducing the risk of thermal failure of the battery cell 1100, and facilitating the smooth completion of the battery cell 1100 testing process.

[0064] See also Figure 1 、 Figure 2 and Figure 4 In some embodiments, the conductive terminal 22 includes a conductive surface 223 , which is used to contact the conductive probe 310 , and the conductive surface 223 is perpendicular to the top surface 14 of the disk body 10 .

[0065] Specifically, the conductive surface 223 is the surface of the conductive terminal 22 facing away from the battery cell 1100. The conductive surface 223 can be a flat surface, and its shape includes but is not limited to a circle or a square. The top surface 14 of the tray 10 is generally arranged horizontally to provide greater stability for the battery cell 1100. The conductive surface 223 is perpendicular to the top surface 14 of the tray 10, that is, the conductive surface 223 can be a vertical surface. During the movement of the conductive probe 310, the conductive probe 310 generally moves horizontally, which increases the contact area between one end of the conductive probe 310 and the conductive surface 223.

[0066] Therefore, the conductive surface 223 is perpendicular to the top surface 14 , making the contact between the conductive surface 223 and the conductive probe 310 more stable. The conductive terminal 22 can be electrically connected to an external testing device through the conductive probe 310 , thereby improving the stability of the battery cell 1100 test.

[0067] See also Figure 3 and Figure 4 In some embodiments, the tray 100 includes a wire 40 , one end of which is connected to the conductive terminal 22 , and the other end of which is used to connect to the battery cell 1100 or the sensor.

[0068] Specifically, the wire 40 can be a flexible wire. One end of the wire 40 can be fixedly connected to the conductive terminal 22, for example, by welding the conductive terminal 22. The other end of the wire 40 can be detachably connected to the battery cell 1100, for example, by attaching the wire 40 to the battery cell 1100 using adhesive. The cross-section of the wire 40 matches the current-passing surface of the conductive terminal 22. Thus, the connection between the conductive terminal 22 and the battery cell 1100 via the wire 40 provides a more stable electrical connection between the conductive terminal 22 and the battery cell 1100.

[0069] In some embodiments, the wire 20 includes a first wire 41 and a second wire 42, the cross-sectional area of ​​the first wire 41 is larger than the cross-sectional area of ​​the second wire 42, the first wire 41 is connected to the first terminal 221, and the second wire 42 is connected to the second terminal 222, so that the cross-sectional area of ​​the conductive terminal 22 matches the cross-sectional area of ​​the wire 40.

[0070] Please refer again Figure 1 and Figure 2 In some embodiments, the testing device 1000 further includes an electrical transfer mechanism 300 , which includes a plurality of pairs of conductive probes 310 , and the conductive probes 310 are configured to abut against the conductive terminals 22 .

[0071] Specifically, the conductive probe 310 can be cylindrical. The conductive probe 310 can maintain electrical connection with external testing equipment. After the conductive probe 310 contacts the conductive terminal 22, the battery cell 1100 can be electrically connected to the external testing equipment. In this way, the testing device 1000, through the conductive probe 310 of the electrical adapter mechanism 300 abutting the conductive terminal 22, allows the battery cell 1100 to be electrically connected to the external testing equipment through the conductive terminal 22 and the conductive probe 310, facilitating smooth testing of the battery cell 1100.

[0072] In some embodiments, the supporting mechanism 200 includes a supporting plate 210 and a bracket 220 disposed on the supporting plate 210 , and the tray 100 is disposed on the bracket 220 . There are multiple brackets 220 , and the multiple brackets 220 are arranged at intervals, with a tray 100 disposed on each bracket 220 .

[0073] Specifically, the support plate 210 is a foundational component of the support mechanism 200 and provides support for the bracket 220. The support plate 210 can be made of a strong material such as steel or aluminum alloy, ensuring that the support mechanism 200 is not easily deformed when carrying the tray 100 and battery cells 1100. This facilitates accurate contact between the conductive terminals 22 and the conductive probes 310, allowing for smooth testing of the battery cells 1100.

[0074] The carrier plate 210 provides support for the bracket 220, which in turn supports the tray 100, thereby stabilizing the position of the tray 100 and enabling smooth testing of the battery cells 1100. Multiple brackets 220 and trays 100 can be used to simultaneously test multiple battery cells 1100, improving the efficiency of testing the battery cells 1100.

[0075] Please refer again Figure 1 and Figure 2 In some embodiments, the testing device 1000 may further include a driving assembly 400, which is connected to the power adapter mechanism 300 and is configured to drive the power adapter mechanism 300 to abut or separate from the power connection mechanism 20. In this way, the driving assembly 400 drives the power adapter mechanism 300 to abut or separate from the power connection mechanism 20, allowing external testing equipment to collect parameters of the battery cell 1100 through the power adapter mechanism 300 and the power connection mechanism 20, thereby automating the testing of the battery cell 1100. This eliminates the need for manual connection between the battery cell 1100 and the external testing equipment, thereby improving the testing efficiency of the battery cell 1100.

[0076] The test system of the present invention includes the test device 1000 of any of the above embodiments. The test system may include external test equipment and a transfer device. The transfer device may be, for example, a manipulator or the like.

[0077] In one embodiment, when testing the battery cell 1100, the battery cell 1100 can be first placed on the tray 100 and fixed with a fixing element such as a strap, and then the battery cell 1100 can be connected using a wire 40, or a sensor can be arranged on the battery cell 1100. Thereafter, the tray 100 with the battery cell 1100 can be transferred to the supporting mechanism 200 by a transport device, and then the conductive probe 310 of the electrical adapter mechanism 300 is brought into contact with the conductive terminal 22, so that the external testing equipment can collect the parameters of the battery cell 1100, thereby completing the test of the battery cell 1100.
