Description

Technical Field

[0001] This utility model relates to the field of battery cell testing technology, specifically to a multi-channel, equally spaced needle bed probe spacing adjustment device. Background Technology

[0002] A battery cell testing probe bed module is a device used for testing batteries (especially lithium batteries). It is mainly used to test the electrical performance of battery cells. The module usually consists of multiple probes that can be connected to the battery's contact points to measure parameters such as battery voltage, current, and internal resistance.

[0003] However, the design and use of traditional battery cell testing probe bed modules are limited by the assembly method of the required battery cell tray, which restricts the spacing of the probe group and the number of testing channels. When the required number of test cell channels and spacing change, the currently used probe bed cannot be used and needs to be redesigned and put into production. This increases the cost of using the battery cell testing device. In order to make the battery cell testing device more versatile and reduce the cost of using the device, a multi-channel equally spaced probe bed spacing adjustment device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a compatible multi-channel equally spaced needle bed probe spacing adjustment device. It has the advantages of good versatility and reduced usage costs. It solves the problem that the design and use of traditional battery cell testing needle bed probe modules are limited by the assembly method of the required battery cell tray, which restricts the spacing of the probe group and the number of testing channels. When the required number and spacing of the battery cell testing channels change, the currently used needle bed cannot be used and needs to be redesigned and put into production, which increases the usage cost of the battery cell testing device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-channel equidistant needle bed probe spacing adjustment device, comprising a mounting frame, an adjustment limiting shaft rotatably mounted on the surface of the mounting frame, a double-pitch adjusting cylinder sleeved on the surface of the adjustment limiting shaft, a probe adjusting bracket and a screw sleeve threadedly connected to the outer surface of the double-pitch adjusting cylinder, a probe fixing bracket fixedly mounted on the surface of the screw sleeve, a probe fixedly mounted on the surface of the probe fixing bracket, and an adjusting nut fixedly mounted on one end of the adjustment limiting shaft.

[0006] Furthermore, a protective plate is fixedly installed on the surface of the mounting frame, and a mounting pad is fixedly installed on the surface of the protective plate.

[0007] Furthermore, an adjustment display located outside the mounting frame is sleeved on the surface of the adjustment limiting shaft.

[0008] Furthermore, the surface of the dual-pitch adjusting cylinder is designed with two sections of threads with different pitches. The thread pitch of the section in contact with the probe adjusting bracket and the surface of the dual-pitch adjusting cylinder is 1.0; the thread pitch of the section in contact with the screw sleeve shaft and the surface of the dual-pitch adjusting cylinder is 2.0.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] This multi-channel, equally spaced needle bed probe spacing adjustment device adjusts the spacing by mounting the probes on a screw mechanism and utilizing the screw's transmission performance to achieve equally spaced, synchronous adjustment based on different screw pitch combinations. When the number of channels needs to be increased or decreased, the combined adjusting screw structure can be added or removed as needed. When the thickness of the battery cell changes, thus altering the spacing, the adjusting screw structure can achieve freely adjustable equally spaced spacing. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 2This embodiment discloses a multi-channel, equally spaced needle bed probe spacing adjustment device, comprising a mounting frame 1, a protective plate 9 fixedly mounted on the surface of the mounting frame 1, a mounting pad 10 fixedly mounted on the surface of the protective plate 9, an adjustment limit shaft 2 rotatably mounted on the surface of the mounting frame 1, a double-pitch adjustment cylinder 3 sleeved on the surface of the adjustment limit shaft 2, a probe adjustment bracket 4 and a screw sleeve shaft 5 threadedly connected to the outer surface of the double-pitch adjustment cylinder 3, the surface of the double-pitch adjustment cylinder 3 being designed with two sections of threads with different pitches, the thread pitch of the contact section between the probe adjustment bracket 4 and the surface of the double-pitch adjustment cylinder 3 being 1.0; the thread pitch of the contact section between the screw sleeve shaft 5 and the surface of the double-pitch adjustment cylinder 3 being 2.0, a probe fixing bracket 6 fixedly mounted on the surface of the screw sleeve shaft 5, a probe 7 fixedly mounted on the surface of the probe fixing bracket 6, an adjustment nut 8 fixedly mounted on one end of the adjustment limit shaft 2, and an adjustment display 11 located outside the mounting frame 1 sleeved on the surface of the adjustment limit shaft 2.

[0016] It should be noted that when the adjusting limit shaft 2 rotates one revolution, the 1.0 pitch section of the double pitch adjusting cylinder 3 is driven by 1 mm; the 2.0 pitch section is driven by 2 mm; thus ensuring that the two sets of probes 7 achieve equal spacing adjustment.

[0017] An adjustment display 11 is designed in front of the adjusting nut 2-1 to achieve visual equidistant adjustment. When adjusting, the change in the value of the adjustment display 11 can be observed to determine the number of turns of the current adjustment limit shaft 2, thereby determining whether the probe 7 spacing is adjusted to the correct position.

[0018] It should be noted that the adjustment limit shaft 2 in this embodiment is an optical shaft with a limit groove, which facilitates the disassembly and assembly of the double pitch adjustment cylinder 3 while also enabling the synchronous rotation of the double pitch adjustment cylinder 3.

[0019] The working principle of the above embodiments is as follows:

[0020] In use, use a tool to screw on the adjusting nut 8 fitted on the adjusting limit shaft 2, which drives the adjusting limit shaft 2 to rotate. The mounting frame 1 limits the position of the double pitch adjusting cylinder 3. The double pitch adjusting cylinder 3 and the screw sleeve shaft 5 fit together. The double pitch adjusting cylinder 3 is designed with two sections of threads with different pitches. When the adjusting limit shaft 2 rotates one revolution, the 1.0 pitch section on the double pitch adjusting cylinder 3 is driven by 1 mm; the 2.0 pitch section is driven by 2 mm. This ensures that the two sets of probes on the double pitch adjusting cylinder 3 achieve equal spacing adjustment.

[0021] By adjusting the display 11, the change in the value of the position display 2-2 can be observed to determine the current number of turns for adjustment, thereby determining whether the probe 7 spacing is properly adjusted.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
