Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and particularly relates to a battery formation and grading needle bed. Background Art

[0002] Before leaving the factory, batteries need to go through the formation and grading process. When carried out in batches simultaneously, a battery formation and grading needle bed is used. Currently, in some battery formation and grading needle beds, the power supply module is integrated in the needle bed. However, when the power supply module fails, users need to disassemble the power supply module for repair.

[0003] In the current battery formation and grading needle bed, test probes are generally integrated on the power supply module of the needle bed frame, and the power supply module is fixed. Thus, the relative position between the test probe and the battery under test is inconvenient to adjust, and misalignment is likely to occur, affecting the test accuracy. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a battery formation and grading needle bed, aiming to solve the problem that the relative position between the test probe and the battery under test is inconvenient to adjust.

[0005] To achieve the above purpose, the battery formation and grading needle bed proposed by the utility model includes:

[0006] A frame, on which multiple columns of guide rails are provided;

[0007] A tray, installed on the frame, and the tray is used for placing a plurality of batteries under test arranged side by side;

[0008] Multiple power supply modules, on which test probes are provided, and slide rails are provided on both sides of the power supply module, and the slide rails can slide relative to the guide rails;

[0009] An adjustment hole is opened at the end of each column of the guide rails, and the adjustment hole is used for a adjusting bolt to pass through and connect to abut against the end of the power supply module, so that the position of the test probe relative to the battery under test can be adjusted;

[0010] A connecting plate, which is used for fixedly connecting the power supply module and the frame.

[0011] Further, each column of the guide rails includes a plurality of sub-guide rails arranged at intervals, and each sub-guide rail includes a bottom plate and a side plate connected perpendicularly to each other. The shape of the slide rail is a cuboid, the bottom plate contacts the bottom surface of the slide rail, and the side plate contacts the side surface of the slide rail.

[0012] Further, in the sub-guide rail at the end, a baffle is connected between the bottom plate and the side plate. The baffle is parallel to the connecting plate, and the adjustment hole is opened on the baffle.

[0013] Furthermore, the sub-guide rail located at the front end protrudes from the front end of the frame.

[0014] Furthermore, a handle is provided on the power module.

[0015] Furthermore, the connecting plate is provided with a plurality of through holes, and the through holes can be connected to the power module or the frame by fixing bolts.

[0016] Furthermore, the frame includes a bracket and an upper frame installed on the bracket, the upper frame includes two vertical beams and a plurality of cross beams connected between the two vertical beams, and the sub-guide rail is arranged on each of the cross beams.

[0017] The process of assembling the power module to the frame in the technical solution of the utility model is as follows: first align the upper slide rail of the power module and place it on the guide rail, then push the power module so that the upper slide rail of the power module slides on the guide rail until it is held by the adjusting bolt at the end. The adjusting bolt can be screwed in or out of the adjusting hole so that the position of the power module can be easily adjusted, thereby achieving the relative position of the test probe on the power module and the battery cell to be tested facing each other.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 6 , the present invention provides a battery formation and capacitance testing needle bed.

[0027] The battery formation and capacitance testing needle bed includes a frame 100, a tray 120, a plurality of power supply modules 200 and a connecting plate 300. A plurality of columns of guide rails 110 are provided on the frame 100; the tray 120 is installed on the frame 100 and is used for placing a plurality of battery cells 121 to be tested arranged in parallel; test probes 210 are provided on the power supply module 200, and slide rails 220 are provided on both sides of the power supply module 200, and the slide rails 220 can slide relative to the guide rails 110; adjustment holes 111 are opened at the ends of each column of guide rails 110, and the adjustment holes 111 are used for a adjusting bolt to pass through and connect to abut against the end of the power supply module 200, so that the position of the test probe 210 relative to the battery cell 121 to be tested can be adjusted; the connecting plate 300 is used to fixedly connect the power supply module 200 and the frame 100.

[0028] Specifically, the battery component capacity needle bed also includes a lifting drive mechanism, etc., which is used to drive the power module 200 to drive the test probe 210 to move, so as to achieve the contact and disconnection between the test probe 210 and the battery cell 121 to be tested. The adjustment hole 111 can be a threaded hole or a conventional hole position. For example: the adjustment hole 111 is a threaded hole, in which case the adjustment bolt only needs to be screwed into the adjustment hole 111; or the adjustment hole 111 is a conventional hole position, in which case the adjustment bolt can be fixedly connected with a nut. The process of assembling the power module 200 to the frame 100 is as follows: first align the slide rail 220 on the power module 200 and place it on the guide rail 110, and then push the power module 200 so that the slide rail 220 on the power module 200 slides on the guide rail 110 until it is supported by the adjusting bolt at the end. The adjusting bolt can be screwed in or out of the adjusting hole 111, so that the position of the power module 200 can be easily adjusted, thereby achieving the relative position of the test probe 210 on the power module 200 and the battery cell 121 to be tested to be aligned. At this time, a good position is selected to keep the power module 200 stationary, and the connecting plate 300 is used to fix the power module 200 on the frame 100, which can ensure that the test probe 210 and the battery cell 121 to be tested are in contact and conductive during the test, thereby completing the battery cell charge and discharge test. With such a configuration, it is only necessary to manually rotate the adjustment bolt and slide the power module 200 to conveniently adjust the position of the test probe 210 on the power module 200 relative to the battery cell 121 to be tested, so that the test probe 210 is directly above the battery cell 121 to be tested, thereby preventing the test probe 210 from being misaligned with the battery cell to be tested, thereby improving installation efficiency and test accuracy.

[0029] See also Figure 1 and Figure 4 Furthermore, each column of guide rails 110 includes a plurality of spaced-apart sub-guide rails 112, each sub-guide rail 112 includes a bottom plate 113 and a side plate 114 vertically connected to each other, and the slide rail 220 is in the shape of a rectangular parallelepiped, the bottom plate 113 contacts the bottom surface of the slide rail 220, and the side plate 114 contacts the side surface of the slide rail 220. It should be noted that, at present, the battery-type capacity needle bed is slidably connected by adapting the slide rail 220 of the power module 200 to the guide rail 110 of the needle bed, but due to the structural shape restrictions of the slide rail 220 of the power module 200 and the guide rail 110 of the needle bed, the two are not easy to be disassembled, so that the power module 200 cannot be disassembled for maintenance, causing inconvenience to maintenance. In this embodiment, the slide rail 220 is set to a rectangular shape, and the sub-guide rail 112 is composed of a bottom plate 113 and a side plate 114, so that the slide rail 220 can be directly overlapped on the sub-guide rail 112 to achieve a sliding connection. When the power module 200 needs to be repaired and disassembled, it only needs to slide the power module 200 to the corresponding position and pick it up for repair. The operation is simple and convenient.

[0030] See also Figure 1 andFigure 4 Further, in the sub-guide rail 112 at the end, a baffle 115 is connected between the bottom plate 113 and the side plate 114, the baffle 115 is parallel to the connecting plate 300, and an adjustment hole 111 is opened on the baffle 115. The bottom plate 113, the side plate 114, and the baffle 115 can be set to be perpendicular to each other, and the shapes of the bottom plate 113, the side plate 114, and the baffle 115 can all be rectangular. When the power module 200 is installed in the frame 100, the adjustment bolt is adjusted to a predetermined position, and the power module 200 is gradually slid in until it is supported by the adjustment bolt or the baffle 115. At this time, it is ensured that the test probe 210 on the power module 200 is directly at the position of the battery cell 121 to be tested.

[0031] See also Figure 1 and Figure 4 Furthermore, the sub-guide rail 112 at the front end protrudes from the front end of the frame 100. With such a configuration, when installing the power module 200, the staff can first place the power module 200 directly on the sub-guide rail 112 at the front end, and then gradually slide it in until the end is supported by the adjusting bolt, which can improve the installation efficiency of the power module 200.

[0032] See also Figure 2 In order to facilitate dragging of the power module 200, a handle 400 is further provided on the power module 200. The staff can use the handle 400 to move the power module 200 and adjust the position of the test probe 210 on the power module 200 relative to the battery cell 121 to be tested.

[0033] See also Figure 1 and Figure 6 In order to facilitate the installation of the power module 200, the connecting plate 300 can also be set to be detachable. Furthermore, a plurality of through holes 310 are provided on the connecting plate 300, and the through holes 310 can be connected to the power module 200 or the frame 100 through fixing bolts. In this way, after the power module 200 is slid and installed into the frame 100 to the bottom, the connecting plate 300 and the power module 200 are first connected by the fixing bolts penetrating the through holes 310, and then the connecting plate 300 and the frame 100 are connected by the fixing bolts, so that the connecting plate 300 can cooperate with the adjusting bolts on the rear side to adapt to different positions of the power module 200, and the front and rear adjusting bolts and the connecting plate 300 are mutually limited and fixedly connected to ensure the connection stability of the power module 200.

[0034] See also Figure 1 and Figure 4, Further, the frame 100 includes a bracket 130 and an upper frame 140 mounted on the bracket 130. The upper frame 140 includes two vertical beams 141 and a plurality of cross beams 142 connected between the two vertical beams 141. Each cross beam 142 is provided with a sub-guide rail 112. Each sub-guide rail 112 is spaced apart, which can save material costs. Each vertical beam 141 and cross beam 142 may all be in the shape of a cuboid.

[0035] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
