Description

Technical Field

[0001] The utility model relates to the technical field of battery testing equipment, and particularly relates to a moving probe follow-up device and a battery restraint device. Background Technique

[0002] During the production and manufacturing process of lithium batteries, it is necessary to test the charging and discharging of the batteries. This is not only a necessary link for quality control but also an important step to ensure product safety, reliable performance, and compliance with market regulations. In the prior art, generally, a battery restraint device is used to test the batteries. During the test, it is required that the test probes of the battery restraint device are directly opposite to the positions of the battery poles to ensure effective contact between the test probes and the battery poles, thereby avoiding affecting the charging and discharging of the batteries.

[0003] However, due to errors in the thickness of the batteries, errors in the thickness of the spacers of the battery restraint device, and the fact that the batteries will expand during charging and discharging, resulting in errors in the thickness of the batteries. In particular, these errors will accumulate in the battery queue, causing the deviation degree between the batteries farther from the blocking platform of the battery restraint device (or closer to the restraint mechanism of the battery restraint device) and their corresponding test probes to reach a level that affects the effective progress of battery charging and discharging. Currently, existing battery restraint devices are all of fixed structures. Once the battery thickness is different, the test probe mechanism needs to be redesigned and manufactured, and they cannot be compatible with batteries of other thicknesses, which is inconvenient to use and has a high cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a moving probe follow-up device and a battery restraint device, which can follow up and adjust the actual position of the probe according to batteries of different thicknesses, thereby solving the problem that the fixed-structure battery restraint device in the prior art cannot be compatible with batteries of different thicknesses.

[0005] The embodiments of the utility model are implemented as follows:

[0006] In the first aspect of the embodiment of the present utility model, a motion probe follower device is provided, which is used to be assembled on one side of a restraint tray. At least two mounting spacers and at least one battery cell to be tested are slidably arranged on the restraint tray. At least two of the mounting spacers and at least one of the battery cells to be tested are alternately arranged in sequence along a first direction. The motion probe follower device includes a probe follower mechanism, and the probe follower mechanism includes a mounting plate, a plurality of follower sliders, a plurality of guiding components, and a plurality of probe components. The plurality of follower sliders are slidably arranged on the mounting plate along the first direction. The guiding components are fixedly arranged on the follower sliders one by one. The probe components are slidably arranged on the follower sliders one by one. Wherein, the same guiding component is docked with two adjacent mounting spacers, and two adjacent guiding components are docked with the same mounting spacer. The mounting spacer is driven to slide relative to the restraint tray along the first direction, so as to drive the follower slider to move synchronously relative to the mounting plate through the guiding component. The probe component is driven to move towards the side close to the restraint tray, so that the probes of the probe component are respectively docked with the pole columns of the battery cells to be tested. This motion probe follower device can adjust the actual position of the probe according to the battery with different thicknesses, thus solving the problem that the battery restraint device with a fixed structure in the prior art cannot be compatible with batteries of different thicknesses.

[0007] As an implementable manner, the guiding component includes a T-shaped frame and two guiding blocks. The cross bar of the T-shaped frame extends along the first direction, and the vertical bar of the T-shaped frame extends along a second direction perpendicular to the first direction. The two guiding blocks are respectively located on opposite sides of the vertical bar. One end of the guiding block is slidably arranged on the cross bar, and the other end of the guiding block is used to be docked with the mounting spacer.

[0008] As an implementable manner, the guiding component further includes two guiding rods. The two guiding rods are arranged corresponding to the two guiding blocks one by one. The guiding block is sleeved on the guiding rod to guide the sliding of the guiding block relative to the cross bar of the T-shaped frame through the guiding rod.

[0009] As an implementable manner, the guiding component further includes two elastic members. The two elastic members are arranged corresponding to the two guiding blocks one by one. The elastic member is sleeved on the guiding rod. Opposite ends of the elastic member are respectively connected to one side of the guiding block and one side of the vertical bar.

[0010] As an implementable manner, the probe component includes a probe, a mounting slider, and a mounting slide rail. The probe is fixedly arranged on the mounting slider. The mounting slider is slidably arranged on the mounting slide rail. The mounting slide rail is fixedly arranged on the follower slider, and the mounting slide rail extends along a second direction perpendicular to the first direction.

[0011] As an implementable manner, the probe assembly further includes a pushing plate and a first driving member. One side of the mounting slider away from the restraint tray is fixedly arranged on the pushing plate, and the first driving member is in transmission connection with the pushing plate and is used to drive the mounting slider to slide along the second direction through the pushing plate.

[0012] As an implementable manner, the moving probe follower device further includes a frame and a second driving member. The probe follower mechanism is movably arranged on the frame, and the second driving member is in transmission connection with the probe follower mechanism and is used to drive the probe follower mechanism to move relative to the frame along a second direction perpendicular to the first direction.

[0013] As an implementable manner, the moving probe follower device further includes a third driving member. The third driving member is in transmission connection with the probe follower mechanism and is used to drive the probe follower mechanism to move relative to the frame along a third direction perpendicular to both the first direction and the second direction.

[0014] As an implementable manner, the moving probe follower device further includes a frame guide rail. The frame guide rail extends along the first direction, and the frame is slidably arranged on the frame guide rail.

[0015] In a second aspect of the embodiments of the present invention, a battery restraint device is provided, including the above-mentioned moving probe follower device. This moving probe follower device can follow and adjust the actual position of the probe according to batteries of different thicknesses, thereby solving the problem that the battery restraint device with a fixed structure in the prior art cannot be compatible with batteries of different thicknesses.

[0016] The beneficial effects of the embodiments of the present invention include:

[0017] The moving probe follower device is used to be assembled on one side of the restraint tray. At least two mounting spacers and at least one battery cell to be tested are slidably arranged on the restraint tray. The at least two mounting spacers and the at least one battery cell to be tested are alternately arranged in sequence along a first direction. The moving probe follower device includes a probe follower mechanism, and the probe follower mechanism includes a mounting plate, a plurality of follower sliders, a plurality of guiding components, and a plurality of probe components. The plurality of follower sliders are slidably arranged on the mounting plate along the first direction. The guiding components are fixedly arranged on the follower sliders in one-to-one correspondence. The probe components are slidably arranged on the follower sliders in one-to-one correspondence. Among them, the same guiding component is docked with two adjacent mounting spacers, and two adjacent guiding components are docked with the same mounting spacer. The mounting spacer is driven to slide relative to the restraint tray along the first direction, so as to drive the follower slider to move synchronously relative to the mounting plate through the guiding component. The probe component is driven to move towards the side close to the restraint tray, so that the probes of the probe components are docked with the pole columns of the battery cells to be tested in one-to-one correspondence. Compared with the battery restraint device with a fixed structure in the prior art, for the battery restraint device provided in the present application, first, by arranging a plurality of follower sliders on the mounting plate to slide along the first direction, a following relationship with parallel sliding directions can be formed between the mounting spacer and the follower slider. Then, due to the special corresponding relationship between the guiding component and the mounting spacer (that is, the same guiding component is docked with two adjacent mounting spacers, and two adjacent guiding components are docked with the same mounting spacer), a following relationship with matching sliding distances can be formed between the mounting spacer and the follower slider. Subsequently, due to the one-to-one mounting relationship between the probe component and the follower slider, the probes of the probe components can be docked with the pole columns of the battery cells to be tested in one-to-one correspondence.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] Please refer to Figures 1 to 6 , an embodiment of the present application provides a battery restraint device, including a moving probe follower device 100 and a restraint tray 200. Among them, at least two mounting spacers 210 and at least one battery under test 220 are slidably arranged on the restraint tray 200. At least two mounting spacers 210 and at least one battery under test 220 are alternately arranged in sequence along the first direction a. The moving probe follower device 100 is assembled on one side of the restraint tray 200 to test the battery under test 220 on the restraint tray 200 through the moving probe follower device 100. The moving probe follower device 100 can follow and adjust the actual position of the probe 141 according to the batteries of different thicknesses, thereby solving the problem that the battery restraint device with a fixed structure in the prior art cannot be compatible with batteries of different thicknesses.

[0033] It should be noted that, as Figure 1 and Figure 2As shown in the figure, the battery restraint device includes a moving probe follower 100 and a restraint tray 200 to carry the battery cell 220 to be tested by the restraint tray 200 and test the battery cell 220 to be tested on the restraint tray 200 through the moving probe follower 100. In addition, the battery restraint device may further include a positioning mechanism, a restraint mechanism, a power supply module, a cooling mechanism, a fire extinguishing mechanism, etc., to position and install the restraint tray 200 through the positioning mechanism, apply a restraint force to the battery cell 220 to be tested through the restraint mechanism, charge and discharge the battery cell 220 to be tested through the power supply module, cool and dissipate heat from the battery cell 220 to be tested through the cooling mechanism, and perform a fire extinguishing operation on the battery cell 220 to be tested that has experienced thermal runaway through the fire extinguishing mechanism. Regarding other mechanisms of the battery restraint device, those skilled in the art can make reasonable selections and designs with reference to the prior art, and no specific limitations are made here.

[0034] During the actual testing process, first, at least one battery cell 220 to be tested and at least two mounting spacers 210 can be slidably arranged on the restraint tray 200. Then, the restraint tray 200 is transported to the feed port of the battery restraint device through an external stacking device, and the restraint tray 200 is positioned and installed through the positioning mechanism. Subsequently, the moving probe follower 100 is used to dock with the battery cell 220 to be tested on the restraint tray 200. Thus, relevant tests can be performed on the battery cell 220 to be tested during the charging and discharging process of the power supply module to the battery cell 220 to be tested, and finally, test results can be obtained.

[0035] The quantitative relationship between the above-mentioned battery cell 220 to be tested and the mounting spacer 210 is that the number of mounting spacers 210 is one more than the number of battery cells 220 to be tested; the positional relationship between the above-mentioned battery cell 220 to be tested and the mounting spacer 210 is that the mounting spacer 210 and the battery cell 220 to be tested are alternately arranged in sequence along the first direction a. In this way, there is one mounting spacer 210 on each of the opposite sides of each battery cell 220 to be tested, which can not only play a role in installing and fixing the battery cell 220 to be tested through the mounting spacer 210, but also play a clamping role on the opposite sides of the battery cell 220 to be tested under the action of the restraint mechanism through the mounting spacer 210, thereby preventing the battery cell 220 to be tested from experiencing a large degree of expansion during the charging and discharging process. Of course, as the battery expansion phenomenon occurs, the magnitude of the restraint force applied by the restraint mechanism needs to be adjusted in real time to avoid battery damage.

[0036] Specifically, as Figure 3 and Figure 4As shown in the figure, the movement probe follower device 100 includes a probe follower mechanism 10. The probe follower mechanism 10 includes a mounting plate 11, a plurality of follower sliders 12, a plurality of guiding components 13, and a plurality of probe components 14. The plurality of follower sliders 12 are slidably arranged on the mounting plate 11 along the first direction a. The guiding components 13 are fixedly arranged on the follower sliders 12 in a one-to-one correspondence. The probe components 14 are slidably arranged on the follower sliders 12 in a one-to-one correspondence. Among them, the same guiding component 13 is docked with two adjacent mounting spacers 210, and two adjacent guiding components 13 are docked with the same mounting spacer 210. The mounting spacer 210 is driven to slide relative to the restraint tray 200 along the first direction a, so as to drive the follower sliders 12 to move synchronously relative to the mounting plate 11 through the guiding components 13. The probe components 14 are driven to move towards the side close to the restraint tray 200, so that the probes 141 of the probe components 14 are docked with the electrode terminals of the cells 220 to be tested in a one-to-one correspondence.

[0037] It should be noted that, as Figure 3 and Figure 4 shown in the figure, the probe follower mechanism 10 includes a mounting plate 11 and a plurality of follower sliders 12. The plurality of follower sliders 12 are slidably arranged on the mounting plate 11 along the first direction a, so as to play the role of mounting and supporting the follower sliders 12 through the mounting plate 11. Moreover, since the movement direction of the follower sliders 12 is parallel to the movement direction of the mounting spacer 210, the mounting spacer 210 can slide relative to the restraint tray 200 along the first direction a, and the follower sliders 12 can slide relative to the mounting plate 11 along the same direction (i.e., the first direction a). On this basis, the probe follower mechanism 10 further includes a plurality of guiding components 13 and a plurality of probe components 14. The guiding components 13 are fixedly arranged on the follower sliders 12 in a one-to-one correspondence. The probe components 14 are slidably arranged on the follower sliders 12 in a one-to-one correspondence, so as to play the role of mounting and supporting the guiding components 13 and the probe components 14 through the follower sliders 12.

[0038] During the actual working process, the following corresponding relationship exists between the above-mentioned guiding component 13 and the mounting spacer 210: The same guiding component 13 is docked with two adjacent mounting spacers 210, and two adjacent guiding components 13 are docked with the same mounting spacer 210. In this way, on the one hand, it can enable two adjacent mounting spacers 210 to drive the same guiding component 13 to slide synchronously relative to the mounting plate 11. On the other hand, it can also enable the same mounting spacer 210 to drive two adjacent guiding components 13 to slide synchronously relative to the mounting plate 11. Also, since the guiding components 13 are fixedly arranged on the follower sliders 12 one by one, not only can two adjacent mounting spacers 210 drive the same follower slider 12 (fixedly connected to the same guiding component 13) to slide synchronously relative to the mounting plate 11, but the same mounting spacer 210 can also drive two adjacent follower sliders 12 (fixedly connected to two adjacent guiding components 13) to slide synchronously relative to the mounting plate 11.

[0039] Through the mutual cooperation of the above two aspects, a follower relationship with matching sliding distances can be established between the mounting spacer 210 and the follower slider 12. That is to say, when the mounting spacer 210 is driven to slide relative to the restraint tray 200 along the first direction a, the guiding component 13 can drive the follower slider 12 to move synchronously relative to the mounting plate 11. Also, since the probe assemblies 14 are slidably arranged on the follower sliders 12 one by one, it can enable the probe assemblies 14 connected to the same follower slider 12 one by one to be aligned with the position of the battery cell 220 to be tested located between two mounting spacers 210. In this way, when the probe assemblies 14 are driven to move towards the side close to the restraint tray 200, the probes 141 of the probe assemblies 14 can be docked with the electrode posts of the battery cell 220 to be tested one by one, so that the moving probe follower device 100 can test the battery cell 220 to be tested.

[0040] Compared with the battery restraint device with a fixed structure in the prior art, for the battery restraint device provided in the present application, firstly, by arranging a plurality of follower sliders 12 to slide on the mounting plate 11 along the first direction a, a follower relationship with parallel sliding directions can be formed between the mounting spacer 210 and the follower sliders 12. Then, through a special corresponding relationship between the guiding component 13 and the mounting spacer 210 (that is, the same guiding component 13 is docked with two adjacent mounting spacers 210, and two adjacent guiding components 13 are docked with the same mounting spacer 210), a follower relationship with matching sliding distances can be formed between the mounting spacer 210 and the follower sliders 12. Subsequently, through a one-to-one mounting relationship between the probe component 14 and the follower sliders 12, the probes 141 of the probe component 14 can be docked with the electrode posts of the cells 220 to be tested one by one. In this way, regardless of how the battery thickness changes, the moving probe follower device 100 provided in the present application can follow and adjust the actual position of the probe 141 according to batteries of different thicknesses, thereby solving the problem that the battery restraint device with a fixed structure in the prior art cannot be compatible with batteries of different thicknesses.

[0041] As an implementable mode, as Figure 1 、 Figure 2 and Figure 5 shown, the guiding component 13 includes a T-shaped frame 131 and two guiding blocks 132. The cross bar 1311 of the T-shaped frame 131 extends along the first direction a, and the vertical bar 1312 of the T-shaped frame 131 extends along the second direction b perpendicular to the first direction a. Moreover, the vertical bar 1312 is located at the middle position of the cross bar 1311 to form the T-shaped frame 131 through the cross bar 1311 and the vertical bar 1312. Among them, the two guiding blocks 132 are respectively located on the opposite sides of the vertical bar 1312. One end of the guiding block 132 is slidably arranged on the cross bar 1311, and the other end of the guiding block 132 is used for docking with the mounting spacer 210. Exemplarily, a groove is arranged on the cross bar 1311 as a sliding groove for the guiding block 132 to slide relative to the cross bar 1311.

[0042] In this way, when the two guiding blocks 132 respectively abut against the opposite sides of the longitudinal rod 1312, the opening distance between the two guiding blocks 132 is the smallest. Correspondingly, at this time, the thickness of the battery cell 220 to be tested is the smallest. Therefore, the width of the longitudinal rod 1312 in the first direction a (or the smallest opening distance between the two guiding blocks 132) needs to be designed according to the smallest thickness of the battery cell 220 to be tested, and no specific limitation is made here. When the two guiding blocks 132 move towards the side away from each other, the opening distance between the two guiding blocks 132 gradually increases. Correspondingly, at this time, the thickness of the battery cell 220 to be tested gradually increases. Therefore, the length of the cross rod 1311 in the first direction a (or the largest opening distance between the two guiding blocks 132) needs to be designed according to the largest thickness of the battery cell 220 to be tested, and no specific limitation is made here either.

[0043] As an implementable way, as Figure 5 shown, the guiding assembly 13 further includes two guiding rods 133. The two guiding rods 133 are arranged in one-to-one correspondence with the two guiding blocks 132. The guiding block 132 is sleeved on the guiding rod 133 to guide the sliding of the guiding block 132 relative to the cross rod 1311 of the T-shaped frame 131 through the guiding rod 133, so as to avoid the phenomenon that the guiding block 132 tilts itself during the sliding process relative to the cross rod 1311 when the length of the guiding block 132 in the second direction b is long. Exemplarily, in the actual use process, a screw rod with a threaded surface at one end, a smooth surface in the middle section, and a nut at the other end can be used as the guiding rod 133. In this way, one end of the screw rod can be threadedly connected to the longitudinal rod 1312 for easy disassembly and assembly, and the other end of the screw rod can also abut against the guiding block 132. That is to say, when the two guiding blocks 132 move towards the side away from each other until they abut against the nuts of the corresponding screw rods, the opening distance between the two guiding blocks 132 reaches the maximum, and, under the action of the nuts, the phenomenon that the guiding block 132 falls off from the guiding rod 133 (and the cross rod 1311) can be avoided.

[0044] As an implementable way, as Figure 5 shown, the guiding assembly 13 further includes two elastic members 134. The two elastic members 134 are arranged in one-to-one correspondence with the two guiding blocks 132. The elastic member 134 is sleeved on the guiding rod 133, and the opposite ends of the elastic member 134 are respectively connected to one side of the guiding block 132 and one side of the longitudinal rod 1312. On the basis that the installation spacer 210 drives the guiding block 132 to slide synchronously along the cross rod 1311, by arranging the elastic member 134 between the guiding block 132 and the longitudinal rod 1312, under the action of the elastic potential energy of the elastic member 134, it can not only assist the sliding of the guiding block 132 along the cross rod 1311, but also improve the reliability of the docking between the guiding block 132 and the installation spacer 210.

[0045] As an implementation method, Figure 4 and Figure 6 As shown, the probe assembly 14 includes a probe 141, a mounting slider 142 and a mounting rail 143. The probe 141 is fixedly mounted on the mounting slider 142, the mounting slider 142 is slidably mounted on the mounting rail 143, the mounting rail 143 is fixedly mounted on the follower slider 12, and the mounting rail 143 extends along a second direction b perpendicular to the first direction a. Thus, the probe 141 can be driven by the mounting slider 142 to move relative to the mounting rail 143 along the second direction b toward the side close to the battery cell 220 to be tested, so as to dock with the pole on the battery cell 220 to be tested.

[0046] As an implementation method, Figure 3 and Figure 4 As shown, the probe assembly 14 further includes a push plate 144 and a first driving member 145. The side of the mounting sliders 142 of the multiple probe assemblies 14 away from the restraint tray 200 is fixedly arranged on the push plate 144. The first driving member 145 is in transmission connection with the push plate 144, and is used to drive the mounting sliders 142 to slide along the second direction b through the push plate 144. Thus, the push plate 144 can be driven to move by the first driving member 145, thereby driving the multiple mounting sliders 142 to move synchronously, and then the probes 141 on the multiple mounting sliders 142 to move synchronously.

[0047] In addition, if Figure 6 As shown, the probe assembly 14 may also include a wiring harness 146, which is connected to the power module through the wiring harness 146, so as to charge and discharge the battery cell 220 to be tested; the probe assembly 14 may also include a temperature sensing head 147, which is used to monitor the temperature of the battery cell 220 to be tested in real time through the temperature sensing head 147, so as to avoid poor cooling of the battery cell 220 to be tested as much as possible, which may easily cause thermal runaway; the probe assembly 14 may also include a tension spring 148, which is connected between the mounting slider 142 and the push plate 144 to ensure that multiple probe assemblies 14 remain flush.

[0048] As an implementation method, Figures 1 to 3As shown, the moving probe follower device 100 further includes a frame 20 and a second driving member 30. The probe follower mechanism 10 is movably arranged on the frame 20. The second driving member 30 is in transmission connection with the probe follower mechanism 10 and is used to drive the probe follower mechanism 10 to move relative to the frame 20 along a second direction b perpendicular to the first direction a. In the initial state, the probe follower mechanism 10 can be arranged at an interval from the restraint tray 200. After the restraint tray 200 is installed in place, under the action of the second driving member 30, the probe follower mechanism 10 moves relative to the frame 20 toward the side close to the restraint tray 200, so that the same guiding component 13 is docked with two adjacent mounting spacers 210, and two adjacent guiding components 13 are docked with the same mounting spacer 210.

[0049] As an implementable manner, as Figures 1 to 3 shown, the moving probe follower device 100 further includes a third driving member 40. The third driving member 40 is in transmission connection with the probe follower mechanism 10 and is used to drive the probe follower mechanism 10 to move relative to the frame 20 along a third direction c perpendicular to both the first direction a and the second direction b. Thus, the moving probe follower device 100 can be matched with the to-be-tested battery cells 220 of different heights, or in other words, the to-be-tested battery cells 220 with different pole post heights, thereby improving the compatibility of the moving probe follower device 100.

[0050] As an implementable manner, as Figure 1 and Figure 2 shown, the moving probe follower device 100 further includes a frame guide rail 50. The frame guide rail 50 extends along the first direction a, and the frame 20 is slidably arranged on the frame guide rail 50, so that the moving probe follower device 100 can be installed and disassembled along the frame guide rail 50, which is convenient for overhauling the moving probe follower device 100.
