Description

Technical Field

[0001] This utility model relates to the field of flatness measurement technology, and in particular to a multi-position flatness measurement device. Background Technology

[0002] With the development of new energy vehicle technology and the continuous increase in market demand, battery modules, as the core component of electric vehicles, require strict control of their bottom flatness during the manufacturing process to meet the requirements of bottom adhesive coating.

[0003] Currently, the flatness of the bottom of the module in the manufacturing process often needs to be measured one cell at a time using a feeler gauge. This is time-consuming and labor-intensive, and it can also cause the feeler gauge to be inserted into the bottom of the cell at different positions, affecting the measurement accuracy of the cell flatness.

[0004] Therefore, a device is needed that can be used to quickly measure the flatness of the bottom of each cell in a module. Utility Model Content

[0005] The main objective of this invention is to provide a multi-position flatness measuring device, which aims to improve the measurement efficiency of battery cells while ensuring the measurement accuracy of battery cell flatness.

[0006] To achieve the above objectives, this utility model proposes a multi-position flatness measuring device comprising:

[0007] A positioning box is provided with several through grooves, and a measuring hole is provided on the side wall of the positioning box, the measuring hole communicating with the grooves;

[0008] A measuring assembly comprising a plurality of measuring units disposed in the slide, the number of measuring units being at most the same as the slide;

[0009] A telescopic mechanism, the output end of which is connected to the measuring unit, drives the measuring unit to move out or in from the end of the slide.

[0010] In the above scheme, multiple slides are horizontally arranged to ensure that the measuring unit can move into or out of the slide in a horizontal direction, further improving measurement efficiency. A scale is provided on one side of the measuring orifice, which is opened vertically from the top surface of the positioning box towards the slide, allowing the measuring orifice to see the moving measuring unit within the slide. This helps personnel observe the scale indicated by the measuring unit. Preferably, the periphery of the measuring orifice is set as a zero-gradient line, making it easy for personnel to observe and read the actual measurement scale. The number of measuring units corresponds to the number of slides; however, a measuring unit may also correspond to only a portion of the slides, and specific requirements can be selected as needed.

[0011] Furthermore, the measuring unit includes a measuring block, a protrusion, and a feeler gauge. The protrusion is connected to at least one side wall of the measuring block, the feeler gauge is located at the end of the measuring block away from the telescopic mechanism, and the groove is configured to conform to the cross-section of the measuring unit.

[0012] Furthermore, the protrusion is located on the opposite side of the measuring block.

[0013] Furthermore, the protrusion is integrally formed with the measuring block.

[0014] Furthermore, the protrusion is detachably connected to the side wall of the measuring block.

[0015] Furthermore, the number of measuring holes corresponds one-to-one with the number of grooves and is placed at the measuring end of the groove.

[0016] Furthermore, the telescopic mechanism includes a push plate and mounting rods, a plurality of mounting rods being connected to the side of the push plate facing the positioning box and corresponding to the slide groove, and the mounting rods being connected to the measuring block.

[0017] Furthermore, the measuring block and the mounting rod are connected to the same elastic element at opposite ends, and both the measuring block and the mounting rod have mounting holes at opposite ends, which cover the end of the elastic element.

[0018] Furthermore, the telescopic mechanism includes a fixed plate and a screw. The screw is threadedly connected to the fixed plate, and one end of the screw is connected to the push plate. When the screw is threaded forward, it drives the push plate to move towards the positioning box.

[0019] The above technical solution has the following advantages:

[0020] This invention improves the synchronization and speed of measurement by moving several measuring units in and out of the groove of the positioning box, thereby enabling multiple measuring units to move synchronously from the end of the groove to the bottom of several battery cells. At the same time, it avoids the need for the original feeler gauge to measure each individual battery cell, greatly improving the measurement efficiency of the battery cells.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0028] like Figure 1 and Figure 2 As shown, a multi-position flatness measuring device includes a positioning box 3, a measuring component 4, and a telescopic mechanism 2. The positioning box 3 is provided with a plurality of through grooves 31, and a measuring hole 32 is opened on the side wall of the positioning box 3, which communicates with the grooves 31. The measuring component 4 has a plurality of measuring units 41 placed in the grooves 31, and the number of measuring units 41 is at most the same as the number of grooves 31. The output end of the telescopic mechanism 2 is connected to the measuring unit 41 and drives the measuring unit 41 to move out or in from the end of the groove 31. The slides 31 are arranged in multiple ways, and are set at the same height. Preferably, the slides 31 are set horizontally to ensure that the measuring unit 41 can move into or out of the slides 31 in a horizontal direction, thereby improving measurement efficiency. The measuring hole 32 is provided with a scale on one side. The measuring hole 32 is opened vertically from the top surface of the positioning box 3 toward the slide 31, so that the measuring unit 41 moving in the slide 31 can be seen from the measuring hole 32. This helps the personnel to observe the scale pointed to by the measuring unit 41. Preferably, the periphery of the measuring hole 32 is set as a zero scale line, so that the actual measurement scale can be observed by the personnel and the reading can be easily read. The number of measuring units 41 corresponds to the number of slides 31. The measuring units 41 may also correspond to only some of the slides 31. The specific requirements can be selected as needed.

[0029] like Figure 2 and Figure 4As shown, the measuring unit 41 includes a measuring block 411, a protrusion 412, and a feeler gauge 413. The protrusion 412 is connected to at least one side wall of the measuring block 411, and the feeler gauge 413 is located at the end of the measuring block 411 away from the telescopic mechanism 2. The slide groove 31 is configured to conform to the cross-section of the measuring unit 41. The measuring block 411 is slidably connected to the inner wall of the slide groove 31, and the protrusion 412 protrudes from the side wall of the measuring block 411 and is embedded in the inner wall of the slide groove 31. During the sliding process of the measuring block 411, the protrusion 412 can improve the stability of the measuring block 411. The slide groove 31 is opened according to the shape of the measuring block 411 and the protrusion 412. In addition, the feeler gauge 413 of the measuring unit 41 can also be replaced by a knife-edge straight edge.

[0030] Specifically, the protrusions 412 are preferably located on opposite sides of the measuring block 411, i.e., on the left and right sides of the measuring block 411, which can greatly improve the stability of the movement of the measuring block 411. The protrusions 412 and the measuring block 411 are integrally formed. The measuring block 411 and the protrusions 412 are directly drawn together by a mold to form the required structure, reducing costs. In addition, the protrusions 412 are detachably connected to the side wall of the measuring block 411. Specifically, one end of the protrusion 412 is embedded into the measuring block 411 and locked in place when embedded to the limit position, thus completing the detachable connection between the protrusion 412 and the measuring block 411. The middle part of the protrusion 412 can be directly locked onto the measuring block 411 by bolts, rivets, or other means to ensure that the protrusion 412 can be fixed on the measuring block 411.

[0031] like Figure 1 and Figure 2 As shown, the measuring orifice 32 can be a single transverse groove, which only needs to connect multiple slides 31 to observe the moving measuring unit 41 in each slide 31. Preferably, the number of measuring orifices 32 corresponds one-to-one with the slides 31 and is placed at the measuring end of the slide 31.

[0032] like Figures 1-4 As shown, this application includes a base plate 1, a positioning box 3 fixedly installed on the upper surface of the base plate 1, and a telescopic mechanism 2 including a push plate 23 and mounting rods 24. Several mounting rods 24 are connected to the side of the push plate 23 facing the positioning box 3 and correspond to the slide groove 31. The mounting rods 24 are connected to the measuring block 411. The push plate 23 moves on the upper surface of the base plate 1 and moves towards or away from the positioning box 3. When the push plate 23 approaches the positioning box 3, it drives the measuring unit 41 to move in the slide groove 31 through the multiple mounting rods 24, so that the measuring unit 41 moves out from the measuring end of the slide groove 31. The measuring end of the slide groove 31 is provided with a tray 5. The tray 5 can hold several battery cells, or several battery cells can be placed directly on the measuring end of the slide groove 31. The specific measuring object can be selected as needed.

[0033] The measuring end of the slide groove 31 refers to the end where the object to be measured is placed. By moving the measuring unit 41 out of the measuring end of the slide groove 31, the flatness of the object to be measured can be measured.

[0034] like Figures 2-4 As shown, the same elastic element 42 is connected to the opposite end of the measuring block 411 and the mounting rod 24. The opposite ends of the measuring block 411 and the mounting rod 24 are provided with mounting holes 25, which cover the end of the elastic element 42. Each measuring block 411 and the mounting rod 24 are connected to the elastic element 42. The elastic element 42 is used to buffer and assist in the measurement when the measuring block 411 moves and measures. The setting of the mounting hole 25 allows the end of the elastic element 42 to be embedded, which on the one hand restricts the deformation of the end of the elastic element 42, and on the other hand hides part of the elastic element 42, reducing the risk of corrosion of the elastic element 42. The elastic element 42 is preferably a spring, but airbags, buffers, etc. can also be selected.

[0035] like Figures 2-4 As shown, the telescopic mechanism 2 can be selected in various ways, such as using a telescopic cylinder, such as a pneumatic cylinder or an electric cylinder, or it can be driven by a motor and a lead screw. In this application, manual measurement and observation are used. Preferably, the telescopic mechanism 2 includes a fixed plate 22 and a screw 21. The screw 21 is threadedly connected to the fixed plate 22. One end of the screw 21 is connected to the push plate 23. When the screw 21 is threaded forward, it drives the push plate 23 to push towards the positioning box 3. The fixed plate 22 is fixed to the upper surface of the base plate 1. When the screw 21 rotates, its top end is rotatably connected to the push plate 23, and it drives the push plate 23 to push towards the positioning box 3. The mounting rod 24 and the elastic element 42 drive the measuring block 411 to the measuring end of the slide groove 31, so that the feeler gauge 413 gradually extends into the object being measured. When the wedge-shaped structure at the front end of any feeler gauge 413 is tightly fitted with the bottom gap of the object being measured, the screw 21 is rotated again. The corresponding elastic element 42 is deformed and compressed, and the feeler gauge 413 will no longer move forward. The other feeler gauges 413 will continue to move forward until all feeler gauges 413 stop moving forward. At this point, the flatness parameters at different positions on the bottom of the object being measured can be quickly read through the measuring orifice 32.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
