Description

Technical Field

[0001] This invention relates to the field of battery testing technology, and more specifically to a rapid testing device for new energy vehicle batteries. Background Technology

[0002] New energy vehicle batteries are power devices with electrochemical energy storage technology at their core. They mainly use lithium-ion batteries as energy carriers and achieve the storage and release of electrical energy through the oxidation-reduction reaction of positive and negative electrode materials and electrolytes. They have the characteristics of high energy density and long cycle life. With the help of the electronic control system, the charging and discharging process is precisely controlled to provide continuous power to the vehicle. At the same time, they emphasize safety, fast charging performance and the application of environmentally friendly materials.

[0003] However, existing new energy vehicle battery testing devices often have the following problems when in use:

[0004] Currently, when testing the surface flatness of new energy vehicle batteries, a single-point, multiple-coverage method is often used. This method often makes it difficult to continuously test the flatness of the battery surface, resulting in low battery testing efficiency. Secondly, new energy vehicle batteries come in various widths and sizes, making it impossible to adaptably and quickly test batteries of different widths, thus resulting in poor battery testing versatility. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rapid testing device for new energy vehicle batteries, which can effectively solve the problems of the difficulty in continuously testing the flatness of the battery surface, resulting in low battery testing efficiency, and the inability to adapt to rapid testing of batteries with different widths, resulting in poor battery testing versatility.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a rapid testing device for new energy vehicle batteries, comprising:

[0008] A detection base, wherein two lateral support frames are fixedly connected to the upper end face of the detection base;

[0009] A rapid detection component includes two transverse limiting slide rails fixedly connected to the upper positions of the outer walls of two lateral support frames. A transverse moving frame is slidably connected to the inner sides of the two transverse limiting slide rails. A reciprocating ball screw is rotatably connected to the side wall of the transverse moving frame. A translation slider is threaded onto the reciprocating ball screw. A laser ranging sensor is fixedly installed on the lower end face of the translation slider. The two ends of the reciprocating ball screw pass through the two lateral support frames respectively, and both ends are fixedly connected to transmission gears. Transmission gear plates are fixedly connected to the outer walls of the two lateral support frames. The two transmission gears mesh with the two transmission gear plates respectively. A detection drive component is fixedly connected to the outer walls of the lateral support frames.

[0010] The outer wall of the translation slider is fixedly connected to a detection mark assembly, and the upper surface of the transverse frame is fixedly connected to two spacing adjustment assemblies.

[0011] Furthermore, the detection drive component includes a linear guide rail fixedly connected to the outer wall of the lateral support frame, a plurality of rollers slidably connected on the linear guide rail, a fixed bracket fixedly connected to the upper end of the plurality of rollers, a stepper motor fixedly installed in the middle of the fixed bracket, and the output end of the stepper motor fixedly connected to the end of the reciprocating ball screw through a coupling.

[0012] Furthermore, the lateral support frame is provided with a strip-shaped sliding hole, and the reciprocating ball screw is in contact with and rolls with the inner side of the strip-shaped sliding hole.

[0013] Furthermore, the detection marking assembly includes a T-shaped plate fixedly connected to the outer wall of the translation slider. A limiting sliding hole is provided on the side wall of the transverse frame. The end of the T-shaped plate near the translation slider is in contact with the limiting sliding hole and slides. A support plate is fixedly connected to the end of the T-shaped plate away from the translation slider. A sprayer is fixedly connected to the lower end face of the support plate. A PLC controller is fixedly installed on the upper end face of the transverse frame. The PLC controller, the laser rangefinder, the sprayer, and an external power supply are electrically connected.

[0014] Furthermore, the detection marking assembly also includes a liquid storage cylinder fixedly connected to the upper surface of the support plate, and a connecting pipe connects the liquid storage cylinder to the sprayer.

[0015] Furthermore, the spacing adjustment assembly includes two bearing seats fixedly connected to the upper end face of the transverse frame, an adjustment screw is rotatably connected between the two bearing seats, an adjustment slider is threadedly connected to the adjustment screw, an adapter frame is fixedly connected to the lower end face of the adjustment slider, and an abutment collar is fixedly connected to the lower end of the adapter frame, the abutment collar being in sliding engagement with a reciprocating ball screw.

[0016] Furthermore, the spacing adjustment assembly also includes a rotary motor fixedly installed on the outer wall of one of the bearing seats, and the output end of the rotary motor is fixedly connected to the end of the adjustment screw.

[0017] Furthermore, a through hole is provided at the upper end of the transverse frame, and the adapter frame slides in contact with the through hole.

[0018] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0019] 1. The present invention includes a rapid detection component, which drives a reciprocating ball screw to rotate via a stepper motor. The reciprocating ball screw is driven to move by the meshing of a transmission gear and a transmission toothed plate. That is, the reciprocating ball screw can move relative to the lateral support frame when it rotates. At the same time, the reciprocating ball screw can cause the translation slider to move horizontally back and forth when it rotates, which in turn drives the laser range sensor to move synchronously. This allows the laser range sensor to move in a wave-shaped trajectory and perform a comprehensive detection of the battery surface, thereby enabling rapid and continuous detection of the battery surface, which is beneficial to improving battery detection efficiency.

[0020] 2. In this invention, a detection marking component is provided. When the laser rangefinder detects a dent or uneven defect on the battery surface, it can transmit a corresponding electrical signal to the PLC controller, which then sends a start signal to the sprayer. This allows the sprayer to spray a mark onto the corresponding defect location, thereby enabling real-time detection of defect marks for subsequent battery inspection and processing.

[0021] 3. The present invention includes a spacing adjustment component, which drives the adjustment screw to rotate via a rotary motor. This causes the adjustment slider on the adjustment screw to move closer to or further away from the end of the transverse frame, thereby moving the abutment collar closer to or further away from the transverse slider. This adjusts the limiting distance of the abutment collar on the transverse slider, thus facilitating the adjustment of the battery detection width coverage and improving the versatility of battery detection.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to embodiments.

[0032] Example: Refer to Figures 1 to 6A rapid testing device for new energy vehicle batteries includes: a testing base 1 and a rapid testing component 3. Two lateral support frames 2 are fixedly connected to the upper surface of the testing base 1. The rapid testing component 3 includes two transverse limiting slide rails 31 fixedly connected to the upper outer walls of the two lateral support frames 2. A transverse moving frame 32 is slidably connected to the inner side of the two transverse limiting slide rails 31. A reciprocating ball screw 33 is rotatably connected to the side wall of the transverse moving frame 32. A strip-shaped sliding hole 7 is provided on the lateral support frame 2. The reciprocating ball screw 33 rolls and contacts the inner side of the strip-shaped sliding hole 7. A translation slider 34 is threaded onto the reciprocating ball screw 33. A laser ranging sensor 35 is fixedly installed on the lower end face of the translation slider 34. The two ends of the reciprocating ball screw 33 pass through the two side support frames 2 respectively, and the two ends of the reciprocating ball screw 33 are fixedly connected to the transmission gears 36. The outer walls of the two side support frames 2 are fixedly connected to the transmission gear plates 37 respectively. The two transmission gears 36 mesh with the two transmission gear plates 37 respectively. The outer wall of the side support frame 2 is fixedly connected to the detection drive component 4. The detection drive component 4 includes a linear guide rail 41 fixedly connected to the outer wall of the side support frame 2. Several rollers 42 are slidably connected on the linear guide rail 41. The upper end of the several rollers 42 is fixedly connected to the fixed bracket 43. The middle part of the fixed bracket 43 is fixedly installed with a stepper motor 44. The output end of the stepper motor 44 is fixedly connected to the end of the reciprocating ball screw 33 through a coupling.

[0033] Specifically, when the stepper motor 44 drives the reciprocating ball screw 33 to rotate, that is, when the reciprocating ball screw 33 moves horizontally relative to the lateral support frame 2, the sliding cooperation between the rollers 42 and the linear guide rail 41 can fully limit the stepper motor 44, so that the stepper motor 44 can move horizontally synchronously and maintain stable drive of the reciprocating ball screw 33.

[0034] The reciprocating ball screw 33 is driven to rotate by the stepper motor 44. The reciprocating ball screw 33 is driven to move by the meshing transmission of the transmission gear 36 and the transmission tooth plate 37. That is, when the reciprocating ball screw 33 rotates, it can move relative to the lateral support frame 2. At the same time, when the reciprocating ball screw 33 rotates, it can cause the translation slider 34 to move horizontally back and forth, which can drive the laser range sensor 35 to move synchronously. This allows the laser range sensor 35 to move in a wave-shaped trajectory and perform a comprehensive inspection of the battery surface. This enables rapid and continuous inspection of the battery surface, which helps to improve the battery inspection efficiency.

[0035] A detection marking assembly 5 is fixedly connected to the outer wall of the translation slider 34. The detection marking assembly 5 includes a T-shaped plate 51 fixedly connected to the outer wall of the translation slider 34. A limiting sliding hole 52 is opened on the side wall of the transverse frame 32. The end of the T-shaped plate 51 near the translation slider 34 contacts and slides with the limiting sliding hole 52. A support plate 53 is fixedly connected to the end of the T-shaped plate 51 away from the translation slider 34. A sprayer 54 is fixedly connected to the lower end face of the support plate 53. A PLC controller 55 is fixedly installed on the upper end face of the transverse frame 32. The PLC controller 55, the laser range sensor 35, the sprayer 54 are electrically connected to an external power supply. The detection marking assembly 5 also includes a liquid storage cylinder 8 fixedly connected to the upper end face of the support plate 53. A connecting pipe connects the liquid storage cylinder 8 and the sprayer 54.

[0036] When the laser rangefinder 35 detects a dent or unevenness on the battery surface, it immediately transmits a corresponding electrical signal to the PLC controller 55, which then sends a start signal to the sprayer 54. This allows the sprayer 54 to spray a mark onto the corresponding defect location, enabling real-time detection of the defect mark for subsequent battery inspection and processing.

[0037] Two spacing adjustment components 6 are fixedly connected to the upper end face of the transverse frame 32. The spacing adjustment component 6 includes two bearing seats 61 fixedly connected to the upper end face of the transverse frame 32. An adjusting screw 62 is rotatably connected between the two bearing seats 61. An adjusting slider 63 is threadedly connected to the adjusting screw 62. An adapter frame 64 is fixedly connected to the lower end face of the adjusting slider 63. An abutment collar 65 is fixedly connected to the lower end of the adapter frame 64. A through hole 9 is opened at the upper end of the transverse frame 32. The adapter frame 64 is in contact with the through hole 9 and slides. The abutment collar 65 is in sliding contact with the reciprocating ball screw 33. The spacing adjustment component 6 also includes a rotary motor 66 fixedly installed on the outer wall of one of the bearing seats 61. The output end of the rotary motor 66 is fixedly connected to the end of the adjusting screw 62.

[0038] The adjusting screw 62 is driven to rotate by the rotary motor 66, causing the adjusting slider 63 on the adjusting screw 62 to move closer to or away from the end of the transverse frame 32. This, in turn, causes the abutment collar 65 to move closer to or away from the translation slider 34. When the reciprocating ball screw 33 rotates to drive the translation slider 34 to move horizontally, the abutment collar 65 limits the horizontal movement of the translation slider 34. If the translation slider 34 contacts the abutment collar 65 during horizontal reciprocating movement, it will immediately move in the opposite direction to adjust the limiting distance of the abutment collar 65 on the translation slider 34. This allows for convenient adjustment of the battery detection range and improves the versatility of battery detection.

[0039] The working principle of this invention is as follows:

[0040] In use, the battery to be tested is first placed on the testing base 1, and the stepper motor 44 is started. The stepper motor 44 drives the reciprocating ball screw 33 to rotate. The reciprocating ball screw 33 is driven to move by the meshing of the transmission gear 36 and the transmission tooth plate 37. That is, the reciprocating ball screw 33 can move relative to the side support frame 2 when it rotates. At the same time, the reciprocating ball screw 33 can make the translation slider 34 move horizontally back and forth when it rotates, which can drive the laser range sensor 35 to move synchronously, so that the laser range sensor 35 can move in a wave-shaped trajectory and perform a comprehensive detection on the surface of the battery.

[0041] When the drive translation slider 34 moves in a wave-shaped trajectory, if the laser range sensor 35 detects a dent or uneven defect on the battery surface, it can immediately transmit a corresponding electrical signal to the PLC controller 55, and cause the PLC controller 55 to start transmitting a start signal to the sprayer 54, so that the sprayer 54 can spray a mark on the corresponding defect location.

[0042] If the detection coverage needs to be adjusted according to the battery width, the rotary motor 66 can be started to drive the adjusting screw 62 to rotate, causing the adjusting slider 63 on the adjusting screw 62 to move closer to or away from the end of the transverse frame 32. This, in turn, can drive the abutting collar 65 to move closer to or away from the translation slider 34. When the reciprocating ball screw 33 rotates to drive the translation slider 34 to move horizontally, the abutting collar 65 will limit the horizontal movement of the translation slider 34. If the translation slider 34 contacts the abutting collar 65 during horizontal reciprocating movement, it will immediately move in the opposite direction to adjust the limiting distance of the abutting collar 65 on the translation slider 34, thereby adjusting the detection width coverage of the battery.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
