[0003] At present, a Chinese utility model patent application with publication number CN220105695U and publication date November 28, 2023 proposes a battery scanning device, including a base plate and a scanning mechanism; the scanning mechanism includes a column, a first connecting rod and a scanning gun, the column is arranged on the base plate, the first connecting rod is height-adjustably connected to the column, the scanning gun is arranged on the first connecting rod, and is used to scan the identification code on the battery to be tested, and the position of the scanning gun relative to the first connecting rod is adjustable.

[0004] When in use, place the reworked battery to be tested on the bottom plate, adjust the scanning height and angle of the barcode scanner, and scan and retest various types of batteries to be tested.

[0005] With respect to the above-mentioned related technologies, the problem of multiple background colors is often encountered during the battery code scanning process, that is, the background colors of the battery identification code are diverse. When the identification code and the background color of the battery are similar, it is difficult to distinguish the identification code and the background color during the scanning process, resulting in low scanning and recognition efficiency. Utility Model Content

[0006] In order to reduce the influence of the multi-background color problem on the scanning and recognition efficiency of the identification code, the utility model provides a battery scanning structure and a battery detection cabinet.

[0007] First aspect: The utility model provides a battery code scanning structure and a battery testing cabinet, which adopts the following technical solutions:

[0008] A battery code scanning structure, comprising a housing, a code scanning mechanism mounted on the housing, and a power source;

[0009] It also includes a camera, a control unit and a light source, wherein the camera is mounted on the housing, the camera, the code scanning mechanism and the light source are arranged in the same direction, the control unit is mounted inside the housing, the light source is mounted on the housing, and the camera and the light source are electrically connected to the control unit;

[0010] The light sources include a red light source, a green light source and a blue light source.

[0011] By adopting this technical solution, when the battery code scanning structure scans the identification code on the battery, the camera will first identify the background color of the battery identification. After the identification is completed, the control unit calculates the complementary color of the background color of the identification code based on the background color of the battery identification code, and controls the three-color light source to emit the complementary color light, so that the code scanning mechanism can more easily identify the identification code on the battery. After the code scanning mechanism completes the identification code recognition, the control unit stores and uploads the scanning result. According to the complementary light source color, the color corresponding to the background color on the color wheel is selected as the complementary color light source, which can maximize the color contrast between the background color and the identification code, so that the identification code can be more quickly identified when the identification code is recognized by the scanning mechanism, thereby improving the scanning efficiency of the battery code scanning structure.

[0012] Optionally: a concave mirror is also installed on the shell, the concave mirror is arranged corresponding to the light source, the light source is arranged on the concave side of the concave mirror, and the direction of the concave mirror is the same as that of the code scanning mechanism.

[0013] By adopting this technical solution, the light source is arranged on the spherical side of the concave mirror, and the concave mirror faces the direction in which the scanning mechanism scans and identifies the identification code. The light source is installed at the focus of the concave mirror, and the light emitted by the light source can be converged and uniformly reflected in the direction of the identification code, thereby increasing the light intensity of the light source irradiating the identification code, making the color difference between the identification code and the background color more obvious, which is conducive to the scanning mechanism to quickly identify the identification code on the battery.

[0014] Optionally, a diffuser is also installed on the shell, and the diffuser cover is arranged at the opening where the concave mirror reflects light out.

[0015] By adopting this technical solution, the diffuser can diverge the light converged by the concave mirror to increase the effective area of ​​the light source, so that the light emitted by the light source can cover a larger area of ​​the battery surface after being strengthened by the concave mirror. At the same time, the setting of the diffuser can also make the light more evenly dispersed when it is irradiated on the battery and the identification code, reducing the reflection of light on the battery surface and the identification code surface, so that the scanning mechanism can identify the identification code more quickly.

[0016] Optionally: a supporting base plate is further provided on the shell, and a first limiting member and a second limiting member are further provided on the end surface of the supporting base plate close to the code scanning mechanism, and the second limiting member is provided on one side of the first limiting member.

[0017] By adopting this technical solution, when placing the battery, the battery can be placed on the supporting bottom plate, and the two edges of the battery are respectively attached to the first limiter and the second limiter, so that the first limiter and the second limiter limit the position of the battery. When the battery is placed on the bottom plate and scanned for identification, the identification code of the battery can be aligned with the scanning mechanism, increasing the recognition efficiency of the scanning mechanism, and at the same time, it can also avoid the identification code being aligned with the light source position, reducing the light generated by the light source irradiating the surface of the identification code, and improving the recognition efficiency of the identification code by the scanning mechanism.

[0018] Optionally: the second limit member is arranged at the upper edge of the support base plate, and the second limit member is slidably arranged on the support base plate along the extension direction of the first limit member. A linear drive component for driving the second limit member to move is also arranged on the support base plate, and the linear drive component is electrically connected to the control unit by signals.

[0019] By adopting this technical solution, since the size of the battery is not uniform and the position of the identification code relative to the battery is not uniform, directly placing the battery in a fixed position can easily cause the identification code to not align with the scanning mechanism, making it impossible for the scanning mechanism to recognize the identification code. When the second limit component is set at the edge of the support base, the battery is placed at the edge of the support base against the second limit component, and then the limiting component is driven to control the second limit component to drive the battery to move to a position close to the middle until the scanning mechanism can recognize the identification code on the battery and stops moving. In this way, the position of the battery can be adjusted automatically according to the recognition of the scanning mechanism, reducing the situation where the identification code cannot be recognized due to the misalignment between the identification code and the scanning mechanism, so that the scanning mechanism can scan and identify batteries of more sizes and models.

[0020] Optionally: a groove portion is also provided on the supporting base plate, and the groove portion is aligned with the code scanning mechanism.

[0021] By adopting this technical solution, the groove portion can limit the circular battery. When the battery is placed in the groove portion, the rotation of the battery can be reduced, so that the identification code on the circular battery can be quickly aligned with the scanning mechanism, thereby increasing the scanning mechanism's recognition efficiency of the identification code on the circular battery.

[0022] Optionally: a rotating shaft is provided on one side of the groove portion, and a driving shaft is provided on the other side, the rotating shaft and the driving shaft are both rotatably provided on the supporting base plate, the rotating shaft and the driving shaft are provided in parallel, the axial directions of the rotating shaft and the driving shaft are parallel to the extension direction of the groove portion, and the driving shaft is electrically signal-connected to the control unit.

[0023] By adopting this technical solution, when the cylindrical battery is placed in the groove, the identification code is set on the arc surface of the cylindrical battery, and it is not easy to determine whether the identification code is aligned with the code scanning mechanism set above. At this time, the rotating shaft will drive the cylindrical battery placed in the groove to rotate until the code scanning mechanism can recognize that the identification code on the cylindrical arc surface is the rotating mechanism stops rotating and fixes the cylindrical battery in the current position. In this way, the battery is driven to rotate by the driving shaft, which can reduce the probability that the identification code is not aligned with the code scanning mechanism after the battery is placed in the groove, resulting in the code scanning mechanism being unable to recognize the battery identification code.

[0024] Optionally: two shading members are also installed on the shell, and the two shading members are respectively installed at the light inlets of the camera and the code scanning mechanism.

[0025] By adopting this technical solution, the shading member arranged at the light inlet of the camera can reduce the light from the surrounding environment entering the camera, and reduce the interference of the ambient light when the camera recognizes the background color of the identification code. The shading member at the light inlet of the scanning mechanism can reduce the interference caused by the ambient light when recognizing the identification code, and enhance the recognition efficiency of the scanning mechanism for the identification code.

[0026] Second aspect: The utility model provides a battery testing cabinet, which adopts the following technical solutions:

[0027] A battery testing cabinet comprises a cabinet body and a battery code scanning structure as described in the first aspect, wherein the battery code scanning structure is fixedly installed in a detection unit of the cabinet body.

[0028] By adopting this technical solution, the battery is placed in the detection bin, and the position of the battery is limited and fixed by the first and second limiters or grooves set on the support bottom plate of the battery scanning structure, so that the battery can face the scanning mechanism. After the cabinet door is closed, the battery scanning mechanism starts to work, and the battery is sequentially identified by the background color, complementary color light source fill light and scanning recognition, and after the recognition is completed, the identified identification code information is stored and uploaded by the control unit. In this way, the color contrast between the identification code and the background color can be increased by setting the complementary color light source, and the efficiency of the scanning mechanism in identifying the identification code can be increased; the coordinated setting of the first limiter, the second limiter and the linear drive assembly on the support bottom plate can adjust the position of the square battery placed on the support bottom plate, and the setting of the rotating shaft and the driving shaft can adjust the position of the cylindrical battery placed on the support bottom plate, thereby reducing the probability that the identification code on the battery cannot be recognized due to the identification code not being aligned with the scanning mechanism.

[0029] In summary, the present invention includes at least one of the following beneficial technical effects:

[0030] 1. By installing a camera and red, green and blue primary color light sources on the battery detection structure, when the battery identification code is on a different background color, the background color of the identification code can be identified by the camera, and then the complementary color of the background color of the identification code is calculated inside the control unit, and the three primary color light sources are controlled to emit light of complementary colors of the background color to illuminate the identification code and the background color. This can increase the color contrast between the identification code and the background color, and increase the efficiency of the code scanning mechanism in identifying the identification code.

[0031] 2. The setting of the concave mirror and the diffuser on the light source can enhance the light intensity while reducing the reflection caused by the light directly shining on the identification code, thereby improving the recognition efficiency of the identification code by the code scanning mechanism.

[0032] 3. By setting a first limiter on the supporting base plate and a second limiter connected to the linear drive assembly, the position of the battery can be adjusted automatically after being placed on the supporting base plate, thereby reducing the probability that the identification code on the battery cannot be recognized due to the identification code not being aligned with the scanning mechanism, so that the battery scanning structure can scan and identify batteries of more sizes and models, thereby improving the recognition rate of the battery identification code.

[0033] 4. By setting a groove, a rotating shaft and a driving shaft on the supporting base plate, the cylindrical battery can be placed in the groove on the supporting base plate and then the cylindrical battery can be controlled to rotate automatically, thereby reducing the probability that the identification code on the cylindrical battery cannot be recognized due to the identification code not being aligned with the scanning mechanism, and improving the recognition rate of the battery identification code.

[0040] The following combination Figures 1 to 5 The utility model is described in further detail.

[0041] The utility model embodiment discloses a battery code scanning structure and a battery detection cabinet. Figure 1 to Figure 2 A battery detection cabinet includes a cabinet body 9 and a battery code scanning structure. The battery code scanning structure includes a shell 1, a power supply 3, a code scanning mechanism 2, a camera 4, a light source 6, a control unit 5 and a supporting base plate 11. The supporting base plate 11 of the battery code scanning structure is fixedly installed in a detection bin arranged on the cabinet body 9. The shell body 1 is connected above the supporting base plate 11 through a supporting rod. The power supply 3 and the control unit 5 are fixedly installed inside the shell body 1. The code scanning mechanism 2, the camera 4 and the light source 6 are all aligned with the supporting base plate 11.

[0042] Reference Figure 2 The shell 1 includes a shell 1, a support rod and a support base plate 11. The shell 1 and the support base plate 11 are connected through the support rod. The shell 1 is arranged above the support base plate 11. Three mounting holes are opened on the end surface of the shell 1 facing the support base plate 11. The camera 4, the code scanning mechanism 2 and the light source 6 are installed in turn in the three mounting holes. The control unit 5 is fixedly installed inside the shell 1. The camera 4, the code scanning mechanism 2, the light source 6 are all connected to the control unit 5 through wire electrical signals. A connecting block is fixedly connected to the end surface of the shell 1 away from the three mounting holes. The support rod includes a horizontal support rod and a vertical support rod. The connecting block is fixedly clamped on the horizontal support rod by bolts. The horizontal support rod is fixedly connected to one end of the vertical support rod through the connecting block, and the other end of the vertical support rod is fixedly connected to the support base plate 11.

[0043] In this way, by adjusting the position of the connecting quick clamp on the vertical support rod and the horizontal support rod, the position of the shell 1 relative to the supporting base plate 11 can be adjusted, and the camera 4, the code scanning mechanism 2 and the light source 6 on the shell 1 can be flexibly adjusted to align with the position on the supporting base plate 11, which makes it convenient to adjust the code scanning mechanism 2 to align with the identification codes at different positions when testing batteries of different models and sizes.

[0044] Reference Figure 3The support base 11 is connected to a vertical support rod and is provided with a first limiting member 111 and a second limiting member 112 on one end surface. The first limiting member 111 is a limiting rod connected to the support base 11 by bolts. At the same time, the first limiting member 111 can also be a boss structure or a baffle provided on the support base 11. In other embodiments, the limiting effect can be achieved by a convex structure provided on the support base 11. A slide groove is also provided on the side of the first limiting member 111. The extension direction of the slide groove is parallel to the extension direction of the first limiting member 111. A ball screw is also rotatably provided in the slide groove. The axis of the ball screw is in the same direction as the extension direction of the slide groove. One end of the ball screw is fixedly installed on the support The output shaft of the motor on the base plate 11 is connected, and the second limiter 112 is a slider arranged in the slide groove. The slider is provided with a through hole, and a screw sleeve arranged in cooperation with the ball screw is installed inside the through hole. The screw sleeve, the motor and the ball screw together constitute a linear drive component 113 for driving the second limiter component to move in the slide groove. The top of the slider is higher than the bottom surface of the support base plate 11, thereby playing a limiting role. When the motor drives the ball screw to rotate, the screw sleeve arranged in cooperation with the ball screw will drive the slider to move in the slide groove. When the battery is attached to the slider, the slider will move from the edge of the support base plate 11 to the middle position of the support base plate 11, thereby driving the battery to move to the middle position. In other embodiments, the linear drive component 113 can also be a cylinder or a power slide rail installed on the support base plate 11. The second limiter 112 and the piston rod of the cylinder or the second limiter 112 and the moving end of the power slide rail can be fixedly connected to drive the second limiter 112 to move on the support base plate 11.

[0045] In this way, when placing a battery on the supporting base plate 11, the edges of the battery are respectively attached to the edges of the first limit member 111 and the second limit member 112. The second limit member 112 will move from the edge of the supporting base plate 11 to the middle position of the supporting base plate 11 under the drive of the linear drive component 113. After the linear drive component 113 and the control unit 5 are connected by electrical signals, the control unit 5 will determine the position of the battery through the code scanning mechanism 2 in real time. When the code scanning mechanism 2 can recognize the identification code on the battery, the control unit 5 controls the linear drive component 113 to stop moving and complete the code scanning. By linking the code scanning mechanism 2 and the linear drive component 113, the battery code scanning structure can control the position of the battery by itself, thereby reducing the probability that the identification code on the battery is not aligned with the code scanning mechanism 2, resulting in the inability to recognize the identification code.

[0046] Reference Figure 3A groove portion 114 is also provided at the side of the first limit member 111. The groove portion 114 is provided directly below the code scanning mechanism 2. The groove portion 114 is an arc-shaped concave surface provided on the bottom plate. Two rotating shafts 115 are symmetrically provided in the arc-shaped concave surface. One rotating shaft 115 is rotatably provided in the arc-shaped concave surface, and the other rotating shaft 115 is fixedly connected to the output shaft of the stepper motor to form a driving shaft 116. The stepper motor is fixed on the supporting bottom plate 11 and is electrically connected to the control unit 5. The stepper motor has a self-locking function so that the driving shaft 116 has a static holding function when the rotation signal of the control unit 5 is not received. When the cylindrical battery is placed in the groove portion 114, the driving shaft 116 and the rotating shaft 115 can support the cylindrical battery and keep it stationary.

[0047] In this way, when the cylindrical battery is placed in the groove 114, the cylindrical battery can be aligned with the code scanning mechanism 2, and the driving shaft 116 and the rotating shaft 115 can drive the cylindrical battery to rotate in the groove 114. After the driving shaft 116 and the control unit 5 are electrically connected, the control unit 5 can control the driving shaft 116 to rotate, drive the battery to scan the code, and judge the position of the identification code based on the code scanning mechanism 2. When the code scanning mechanism 2 recognizes the identification code on the cylindrical battery, it controls the driving shaft 116 to stop rotating to complete the code scanning; through the linkage setting of the rotating shaft and the control unit 5, when it is impossible to determine whether the identification code on the cylindrical battery is aligned with the code scanning mechanism 2, the cylindrical battery can be rotated automatically to adjust the position of the identification code, thereby reducing the probability that the identification code cannot be recognized due to the identification code on the cylindrical battery not being aligned with the code scanning mechanism 2.

[0048] Reference Figures 4 to 5 The light source 6 includes a concave mirror 61 fixedly mounted on the shell 1 and a three-color light source 6. The concave mirror 61 is fixedly mounted in an opening at the side of the shell 1. The concave mirror 61 is arranged toward the support plate. A red light source 6, a green light source 6 and a blue light source 6 are fixedly mounted at the focus of the concave mirror 61. The red light source 6, the green light source 6 and the blue light source 6 are all LED lamps. The red LED, the green LED and the blue LED are all connected to the control unit 5 by electrical signals.

[0049] In this way, the red light source 6, the green light source 6 and the blue light source 6 are installed at the focus of the concave mirror 61. The concave mirror 61 can converge the light emitted by the three light sources 6 and make it parallel light to irradiate in the direction of the supporting base plate 11. Converging the light source 6 emitted by the LED lamp has the effect of increasing the intensity of light irradiated on the identification code, making the color contrast between the identification code and the background color more obvious, and increasing the recognition efficiency of the identification code by the scanning mechanism 2.

[0050] Reference Figures 4 to 5The end of the concave mirror 61 that emits light is also provided with a threaded structure, and a soft light component 8 is sleeved on the threaded structure. The soft light component 8 is a soft light cover installed on the end of the concave mirror 61 through the threaded structure. At the same time, the soft light component 8 can also be a soft light sheet or concave lens covered on the concave mirror 61, and any structure that can diverge and scatter light.

[0051] In this way, after the concave mirror 61 collects and converges the light emitted by the light source 6, the soft light component 8 can soften and diverge it before irradiating the identification code, so that the light is dispersed more evenly when irradiating the battery and the identification code, reducing the reflection of light on the battery surface and the identification code surface, so that the scanning mechanism 2 can identify the identification code more quickly.

[0052] Reference Figures 4 to 5 The code scanning mechanism 2 is installed in the middle mounting hole on the shell 1, and a shading member 7 is fixedly installed on one side of the code scanning mechanism 2 close to the supporting base plate 11. The shading member 7 is a shading baffle formed by four baffles standing on the edge of the code scanning mechanism 2, and a shading member 7 is also provided at the light inlet of the camera 4.

[0053] In this way, the shading member 7 can play a certain shielding role at the light inlet of the code scanning mechanism 2 and the camera 4, reducing the ambient light entering the code scanning mechanism 2 and the camera 4, allowing the camera 4 to quickly identify the background color of the identification code and the code scanning mechanism 2 to quickly identify the identification code, thereby improving the recognition efficiency.

[0054] The specific working principle of a battery code scanning structure and a battery detection cabinet in an embodiment of the utility model is as follows: open the detection chamber and place the battery with the identification code on the supporting base plate 11; if it is a square battery, stick the edge of the battery to the edge of the first limit piece 111 and the second limit piece 112 to preliminarily determine the position of the battery; after closing the door of the detection chamber, the code scanning mechanism 2 recognizes the identification code in real time; the control unit 5 controls the linear drive assembly 113 to drive the second limit piece 112 to drive the battery to move; after the code scanning mechanism 2 recognizes the identification code on the battery, the control unit 5 controls the second drive member to stop moving to complete the code scanning; if it is a round battery, place the battery on the rotating shaft 115 and the driving shaft 116 of the groove portion 114 on the supporting base plate 11, and stick the identification code on the battery to the edges ... Place the identification code upward to preliminarily determine the position of the cylindrical battery. After closing the door of the detection chamber, the code scanning mechanism 2 recognizes the identification code on the surface of the cylindrical battery in real time, and the control unit 5 controls the drive shaft 116 to rotate and drive the battery to rotate. After the code scanning mechanism 2 recognizes the identification code on the surface of the cylindrical battery, the control unit 5 controls the drive shaft 116 to stop rotating to complete the code scanning; during the scanning and identification process of the identification code by the code scanning mechanism 2, the camera 4 will first identify the battery and the identification code. After the camera 4 recognizes the background color of the identification code, the light source 6 emits a complementary color of the background color according to the signal of the control unit 5. After the light source 6 emits the light, the concave mirror 61 will converge the light emitted by the light source 6. The converged light is scattered by the soft light component 8 and then irradiated on the battery surface.

[0055] In summary, the utility model installs a camera 4 and a red, green and blue primary color light source 6 on the battery detection structure. When the battery identification code is on a different background color, the background color of the identification code can be identified by the camera 4, and the three primary color light source 6 is controlled to emit a light source 6 of a complementary color to the background color to supplement the identification code and the background color, thereby increasing the color contrast between the identification code and the background color and improving the identification code recognition efficiency; the concave mirror 61 and the soft light member 8 can converge the emitted light, enhance the light intensity and avoid the light directly shining on the identification code to produce reflections, thereby improving the identification code recognition efficiency of the code scanning mechanism 2; the first limit member 1 provided on the support base plate 11 11. The cooperation between the second limit member 112 and the linear drive assembly 113 enables the battery scanning mechanism 2 to adjust the position of the battery by itself, thereby reducing the situation where the identification code cannot be recognized due to the misalignment between the identification code and the scanning mechanism 2, and enables the scanning mechanism 2 to scan and identify batteries of more sizes and models; the setting of the groove portion 114, the rotating shaft 115 and the driving shaft 116 enables the battery scanning mechanism 2 to control the rotation of the cylindrical battery and adjust the position of the identification code of the cylindrical battery, thereby reducing the probability that the identification code is not aligned with the scanning mechanism 2 after the battery is placed in the groove portion 114, resulting in the scanning mechanism 2 being unable to recognize the battery identification code.

[0056] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
