Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment technology, and in particular to an automatic battery marking and loading / unloading device. Background Technology

[0002] Button batteries, as miniaturized, high-energy-density power sources, are widely used in consumer electronics, medical devices, and the Internet of Things (IoT). To facilitate product traceability and identification management, laser marking is typically applied to the battery surface. Traditional marking processes require ensuring the clarity and consistency of the markings, while manual operation is inefficient and prone to errors. Therefore, automated marking equipment is urgently needed to meet the demands of large-scale production.

[0003] Currently, most button battery marking equipment adopts a semi-automatic design, requiring manual operation for tasks such as tray loading, positioning, and unloading. This is not only inefficient, but manual intervention can easily lead to misalignment or missed markings. Although some equipment is equipped with a conveyor mechanism, it lacks integrated automatic loading and unloading functions, making continuous operation difficult and affecting overall production efficiency. In addition, manual handling of trays may introduce risks of contamination or impact, which is detrimental to battery quality control. Utility Model Content

[0027] like Figures 1 to 4 As shown, this is an automatic battery marking and unloading device of the present invention, capable of loading, marking, and unloading button batteries. In actual operation, to improve processing efficiency and accuracy, multiple button batteries are placed into a tray for processing. The aforementioned automatic battery marking and unloading device includes a conveying mechanism 10, a loading mechanism 20, an unloading mechanism 30, and a laser marking mechanism 40. The conveying mechanism 10 extends horizontally, while the loading mechanism 20 and the unloading mechanism 30 are respectively located at the starting and ending ends of the conveying mechanism 10, and are used to load and unload the trays, respectively. The laser marking mechanism 40 is located above the middle section of the conveying mechanism 10 to facilitate laser marking of the button batteries in the tray. The laser marking mechanism 40 includes a marking head 41, a focusing unit 42 connected to the marking head 41, and a laser generating unit 43 connected to the marking head 41. Before laser marking, the focusing unit 42 automatically detects the distance between the marking head 41 and the surface of the button battery and adjusts the focus to ensure the quality of laser marking.

[0028] Please see Figure 1 and Figure 2 The conveying mechanism 10 includes a belt conveyor 11 and a servo motor (not shown in the figure) connected by a drive connection; the servo motor is used to drive the belt conveyor 11 to feed the material tray. Specifically, a transmission roller (not shown in the figure) is provided inside the belt conveyor 11, and the drive end of the servo motor is connected to the transmission roller through a coupling to realize transmission.

[0029] Please see Figure 2 It also includes a loading rack 50 and a unloading rack 60. The loading rack 50 is located on the side of the starting end of the conveying mechanism 10 and is used to stack unmarked trays; during operation, the loading mechanism 20 transfers the unmarked trays on the loading rack 50 to the conveying mechanism 10. The unloading rack 60 is located on the side of the ending end of the conveying mechanism 10 and is used to store marked trays; during operation, the unloading mechanism 30 transfers the marked trays on the conveying mechanism 10 to the unloading rack 60 for storage.

[0030] Please see Figures 1 to 3 In this embodiment, the feeding mechanism 20 and the unloading mechanism 30 have identical structures. Both the feeding mechanism 20 and the unloading mechanism 30 include a linear drive assembly 21, a movable seat 22 connected to the linear drive assembly 21, a lifting drive assembly 23 fixed to the movable seat 22, and a gripping assembly 24 fixed to the lifting drive assembly 23. The linear drive assembly 21 drives the movable seat 22 to move horizontally perpendicular to the conveying direction of the conveying mechanism 10; the lifting drive assembly 23 drives the gripping assembly 24 to move vertically. The linear drive assembly 21, the lifting drive assembly 23, and the gripping assembly 24 work together to flexibly and quickly transfer the material tray from the feeding rack 50 to the conveying mechanism 10 and from the conveying mechanism 10 to the unloading rack 60. In addition, to facilitate the assembly of the feeding mechanism 20 and the unloading mechanism 30, and for a reasonable layout, a frame 70 is also provided, on which both the feeding mechanism 20 and the unloading mechanism 30 are mounted.

[0031] Specifically, a slide rail 71 is fixedly mounted on the top of the frame 70, and a slider 221 is fixedly mounted on the bottom of the movable seat 22. The slider 221 is slidably connected to the slide rail 71, enabling the movable seat 22 to slide horizontally. The linear drive assembly 21 includes a transmission rack 211 fixed on the frame 70 and a drive motor 212 fixed on the movable seat 22. The drive motor 212 is vertically positioned, and its output shaft extends vertically downward through the movable seat 22. A transmission gear 213 is fixedly mounted at the bottom of the output shaft. The transmission gear 213 meshes with the rack. The drive motor 212 transmits power through the meshing of the transmission gear 213 and the rack, converting the rotational motion of the output shaft into the horizontal linear motion of the movable seat 22 along the slide rail 71. The rigid meshing of the gear and rack completely avoids positioning errors caused by belt slippage or lead screw backlash, thus improving the accuracy of loading and unloading the material tray. Meanwhile, the gear and rack transmission has the advantage of consistent transmission accuracy in both forward and reverse directions, which meets the needs of the loading mechanism 20 and unloading mechanism 30 in this embodiment for frequent reversing loading and unloading operations.

[0032] Specifically, the lifting drive assembly 23 includes a lifting cylinder 231 and a lifting seat 232 connected by a drive connection; the lifting cylinder 231 is vertically arranged, and a telescopic shaft 233 extends vertically downward through the movable seat 22 from the lifting cylinder 231; the lifting seat 232 is fixed to the bottom of the telescopic shaft 233; the lifting cylinder 231 drives the lifting seat 232 to rise and fall vertically; the gripping assembly 24 is assembled on the lifting seat 232; understandably, the lifting cylinder 231 drives the lifting seat 232 to rise and fall vertically, that is, drives the lifting and falling of the gripping assembly 24, to meet the action requirements of gripping the material tray. Further, multiple guide posts 234 are fixedly provided on the top of the lifting seat 232, and multiple guide sleeves 222 are fixedly provided on the movable seat 22; the guide posts 234 are inserted into the guide sleeves 222 to limit the sway of the lifting seat 232 in the Z-axis direction, improve the movement stability of the lifting seat 232, and ensure the gripping stability of the material tray.

[0033] Specifically, the gripping component 24 includes multiple suction nozzles 241 fixed on the lifting base 232. The top of the suction nozzle 241 is connected to a negative pressure tube, which forms a negative pressure at the suction nozzle 241 to facilitate the adsorption of the material tray and complete the gripping of the material tray.

[0034] Please see Figure 4 The focusing unit 42 includes a Z-axis adjustment module fixed to the top of the marking head 41 and a distance sensor fixed to the bottom of the marking head 41. The sensing end of the distance sensor points vertically downwards and uses an ultrasonic sensor or an infrared sensor to detect the distance between the marking head 41 and the button battery in real time. The distance data is then transmitted to the Z-axis adjustment module, which can drive the marking head 41 to make fine adjustments in the Z-axis direction using a motor drive or other methods to achieve focusing. In addition, a light shield 44 is provided on the side of the marking head 41 to ensure the quality of laser marking. A light-emitting element 45 is also located at the bottom of the marking head 41. The light-emitting element 45 uses LEDs or other lights to provide supplementary illumination, facilitating real-time detection of the marking quality.

[0035] Compared to existing technologies, the automatic battery marking and unloading device of this utility model achieves fully automated marking operations for button battery trays through the coordinated layout of the loading mechanism 20, the conveying mechanism 10, the laser marking mechanism 40, and the unloading mechanism 30. The laser marking mechanism 40 is positioned above the middle section of the conveying mechanism 10, forming a compact linear production layout in conjunction with the loading / unloading mechanisms 30 arranged at both ends. The loading and unloading mechanisms 30 have identical structures and operate independently, improving marking efficiency in conjunction with the belt conveyor 11 driven by a servo motor. Furthermore, the loading and unloading mechanism 30 uses a combination of a gear and rack driven linear motion component and a lifting mechanism with guide columns 234 to achieve precise positioning and movement of the gripping component 24 in the horizontal and vertical directions. In addition, the laser marking mechanism 40 is equipped with a focusing unit 42, which integrates a distance sensor to monitor the marking distance in real time.

[0036] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
