Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular provides an automatic battery rolling device. Background Technology

[0002] In the assembly process of electronic product batteries, rolling is a crucial step to ensure a tight bond between the battery and the casing or adhesive backing. However, existing rolling equipment and processes generally lack precise pressure control mechanisms and effective mechanical buffering mechanisms. This leads to the rolling process relying primarily on operator experience or simple mechanical limits, resulting in uncontrollable and unstable pressure applied to the battery surface. Insufficient pressure can lead to false pressure or mis-pressure, resulting in poor battery adhesion and the risk of detachment; excessive pressure can cause irreversible physical damage to the fragile battery cells due to rigid impact, such as separator perforation or electrode deformation, directly affecting battery safety and lifespan. Therefore, existing technologies suffer from high risks of battery damage and difficulty in guaranteeing product yield. Utility Model Content

[0003] Therefore, it is necessary to provide an automatic battery rolling device to solve at least one of the technical problems in the background art.

The rolling mechanism is installed on the third moving module. The rolling mechanism includes: a linear guide rail, a roller bracket, an elastic buffer assembly, a rolling sensor, and a roller. The roller bracket is installed on the linear guide rail, and the elastic buffer assembly, the rolling sensor, and the roller are arranged sequentially from top to bottom on one side of the roller bracket.

[0005] Preferably, the elastic buffer assembly includes a buffer spring and a rolling guide shaft, the buffer spring being sleeved on the outer periphery of the rolling guide shaft, and one end of the buffer spring abutting against the rolling sensor.

[0009] Preferably, an ion air knife is provided on the outer side of the main body of the chassis, located above the starting end of the movement path of the second moving module.

[0010] Preferably, a barcode scanning assembly is provided inside the main body of the chassis. The barcode scanning assembly includes a barcode scanner and a through-beam fiber optic sensor. The barcode scanner is positioned above the movement path of the second moving module, and the through-beam fiber optic sensor is positioned on both sides of the second moving module.

[0011] The beneficial effects of this utility model are as follows: 1. By setting up a rolling mechanism to perform the pressing operation between the battery and the casing, combined with three lead screw moving modules to realize the precise movement of the jig and rollers that carry the battery products, the rollers are driven to press down vertically, lift up, and reciprocate horizontally, and the rolling path can be completed according to the preset, thus completing the precise pressing between the battery and the casing.

[0012] 2. By incorporating an elastic buffer component to absorb impact and maintain stable pressure, and a rolling pressure sensor to monitor rolling pressure in real time, the rolling pressure can be adjusted in real time through the cooperation of the elastic buffer component and the rolling pressure sensor.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please see Figures 1 to 2 This application provides an automatic battery rolling device, including a chassis body 10, a first movable module 20, a second movable module 30, a third movable module 40 and a rolling mechanism 50, wherein the first movable module 20, the second movable module 30, the third movable module 40 and the rolling mechanism 50 are all adaptedly disposed within the chassis body 10. like Figure 3As shown, the rolling mechanism 50 is mounted on the third moving module 40. The rolling mechanism 50 includes: a linear guide rail 510, a roller bracket 520, an elastic buffer assembly 530, a rolling sensor 540, and a roller 550. The roller bracket 520 is mounted on the linear guide rail 510, and the elastic buffer assembly 530, the rolling sensor 540, and the roller 550 are arranged sequentially from top to bottom on one side of the roller bracket 520.

[0025] Specifically, the roller bracket 520 is slidably connected to the linear guide rail 510 via a rolling slider, the roller roller 550 is rotatably disposed below the roller bracket 520, the rolling sensor 540 is disposed on the other side of the roller bracket 520 away from the roller roller 550, and the elastic buffer assembly 530 abuts against the rolling sensor 540.

[0026] like Figure 3 As shown, the elastic buffer assembly 530 includes a buffer spring 531 and a rolling guide shaft 532. The buffer spring 531 is sleeved on the outer periphery of the rolling guide shaft 532, and one end of the buffer spring 531 abuts against the rolling sensor 540.

[0027] During use, when the roller 550 contacts the battery surface and is subjected to uneven pressure or slight fluctuations during the rolling process, the roller support 520 will push the rolling sensor 540 and compress the buffer spring 531. The elastic deformation of the buffer spring 531 can absorb and buffer the impact, ensuring that the rolling pressure applied to the battery remains dynamically constant. At the same time, the rolling guide shaft 532 provides precise linear guidance for the compression and rebound of the buffer spring 531, effectively preventing the roller support from swaying. This protects the battery from damage caused by sudden pressure changes and ensures the smoothness and consistency of the rolling process.

[0028] The outer periphery of the roller 550 is fitted with an elastic wear-resistant layer.

[0029] Specifically, the material of the elastic wear-resistant layer includes, but is not limited to, silicone or polyurethane. In some embodiments, the overall hardness of the elastic wear-resistant layer is Shore A60-65, which is suitable for protecting the battery surface from damage during rolling. In addition, to facilitate the use of the rolling mechanism 50, the roller 550 is designed to be replaceable to accommodate products with different surface features.

[0030] A scratch-resistant baffle 560 is provided on the outer side of the roller 550.

[0031] Specifically, the anti-scratch baffle 560 is disposed on the side of the roller bracket 520 facing the battery rolling path. The anti-scratch baffle 560 is partially wrapped around the roller 550 and has a gap with the elastic wear-resistant layer on the outer periphery of the roller 550. Its bottom end is lower than the bottom end of the roller 550.

[0032] In some embodiments, the anti-scratch baffle 560 can prevent the edge of the roller 550 and the peripheral components of the rolling mechanism 50 from directly contacting the non-rolling area of ​​the battery. It also prevents friction between the battery and other structures of the equipment when the battery shifts during the rolling process, protecting the integrity of the battery surface. Impurities such as elastic wear-resistant layer debris and environmental dust that may be generated during the rolling process are blocked by the anti-scratch baffle 560. This prevents impurities from adhering to the battery surface and affecting product quality, and also prevents impurities from entering the mating gap between the roller 550 and the linear guide 510, ensuring smooth movement of the rolling mechanism. Simultaneously, its bottom design, lower than the roller, also provides a mechanical limit in abnormal situations, preventing excessive pressure from the roller from damaging the battery, thereby ensuring the reliability of the rolling process and product quality.

[0033] like Figure 2 As shown, the second moving module 30 is used to carry and move the fixture, the first moving module 20 is used to drive the third moving module 40 to move in the horizontal direction, and the third moving module 40 is used to drive the rolling mechanism 50 to move in the vertical direction.

[0034] Specifically, the second moving module 30 is also equipped with a fixture fixing plate, which can be used to place fixtures and battery compartments. By changing the fixtures and adjusting the motion parameters, the equipment can handle batteries of various shapes and sizes within a certain range. For ease of use, the fixture adopts a modular design and is fixed to the fixture fixing plate by positioning pins and quick-change clips. A milled through-hole is cut in the middle of the fixture to avoid gaps. In conjunction with the through-beam fiber optic sensor 720 fixed inside the main body 10, it can be used to detect whether a product is placed on the fixture. If the fixture is empty, the sensor signal is missing, and the equipment will not start the rolling action to prevent air compression.

[0035] Furthermore, the second moving module 30 is used to drive the fixture to move linearly in the horizontal direction. The second moving module 30 is driven by a servo motor and a high-precision ball screw, and works in conjunction with a linear guide rail to ensure the smoothness and accuracy of the fixture's movement. The second moving module 30 is controlled to run according to a preset program, driving the fixture to pass through the ion air knife 60 for dust removal and cleaning, through the barcode scanning component 70 for data scanning and identification, and then through the rolling mechanism 50 for rolling treatment of the products on the fixture.

[0036] Furthermore, the first moving module 20 drives the roller 550 to reciprocate linearly in the horizontal direction to perform the rolling operation. The first moving module 20 and the second moving module 30 are linked by a control system to achieve coordinated work and obstacle avoidance. The third moving module 40 drives the roller 550 to perform vertical pressing and lifting actions. Through the linkage between the third moving module 40 and the first moving module 20, and in conjunction with the high-precision rolling sensor 540 and the elastic buffer assembly 530 on the rolling mechanism 50, the dynamic pressure can be accurately maintained during the rolling process.

[0037] It is worth noting that the rolling mechanism 50 is used to perform the pressing operation between the battery and the casing. Its core includes three moving modules: a first moving module 20, a second moving module 30, and a third moving module 40; a roller 550; and a pressure control mechanism consisting of a rolling sensor 540 and an elastic buffer assembly 530. To facilitate the rolling operation, the second moving module 30 enables the jig carrying the battery product to perform horizontal reciprocating motion. The first moving module 20 and the third moving module 40 are used for the precise movement of the roller 550, driving it to press down vertically, lift, and reciprocate horizontally, thus completing the rolling path according to a preset procedure and achieving precise pressing between the battery and the casing. Furthermore, the elastic buffer assembly 530 absorbs impact and maintains stable pressure, while the rolling sensor 540 monitors the rolling pressure in real time. The rolling pressure can be adjusted in real time through the cooperation of the elastic buffer assembly 530 and the rolling sensor 540. Therefore, the pressure control mechanism formed by the rolling sensor 540 and the elastic buffer assembly 530, together with the movement of the three lead screw moving modules, constitutes a closed-loop control, thereby achieving precise adjustment and maintenance of dynamic pressure during the battery rolling process.

[0038] The first moving module 20, the second moving module 30, and the third moving module 40 are all lead screw modules.

[0039] In some embodiments, the first moving module 20, the second moving module 30, and the third moving module 40 each include a drive motor, a lead screw slide, and a fixed base plate. The drive motor is drivenly connected to the lead screw slide, and the fixed base plate is fixed to the main body of the chassis or an adjacent moving module. The specific structure and drive configuration of the first moving module 20, the second moving module 30, and the third moving module 40 are known to those skilled in the art and are achievable, and will not be described in detail in this embodiment.

[0040] To facilitate equipment use, the first moving module 20, the second moving module 30, and the third moving module 40 achieve micron-level positioning through the screw and nut helical transmission. This ensures precise contact between the rolling mechanism and the battery, preventing uneven rolling due to positioning deviations and guaranteeing consistent battery rolling quality. Furthermore, the low-vibration, smooth transmission characteristics of the aforementioned screw module, combined with the anti-scratch baffle 560 and the elastic buffer component 530, reduce damage to the battery surface. The module's compact structure makes it easy to integrate into the chassis, requiring only periodic lubrication and maintenance to meet the needs of continuous industrial rolling operations.

[0041] Furthermore, the movement speed and acceleration of the first moving module 20, the second moving module 30 and the third moving module 40 are all adjustable, and the coverage width of the rolling operation of the rolling mechanism 50 is adjustable to adapt to different production needs.

[0042] To facilitate the use of the equipment, in some embodiments, the motion control of the equipment can achieve closed-loop control through encoder feedback, thereby ensuring the positional accuracy of the first moving module 20, the second moving module 30, and the third moving module 40, as well as the pressure control accuracy of the rolling mechanism 50. In addition, each moving module is equipped with a limit protection device, including photoelectric and mechanical limit structures, to prevent the moving parts from exceeding the preset stroke and ensure the safe operation of the equipment.

[0043] like Figure 1 As shown, an ion air knife 60 is provided on the outer side of the chassis body 10, located above the starting end of the movement path of the second moving module 30. The ion air knife 60 is fixedly installed on the outer surface of the chassis body 10, located above the starting end of the movement path of the second moving module 30.

[0044] In some embodiments, the ion air knife 60 integrates an ion generator to produce a uniform ion airflow to neutralize static electricity on the product surface and remove adhering substances. The outlet width of the ion air knife 60 is adapted to the width of the fixture, and its outlet air velocity can be adjusted according to different usage requirements via a pneumatic control element. The ion air knife 60 is linked to the equipment control system and automatically starts when the fixture moves under the ion air knife 60. The blowing time is synchronized with the fixture movement speed to ensure continuous cleaning. When the second moving module 30 stops abnormally, the ion air knife 60 automatically shuts down.

[0045] like Figure 5 , Figure 6 As shown, a barcode scanning assembly 70 is provided inside the main body 10 of the chassis. The barcode scanning assembly 70 includes a barcode scanner 710 and a through-beam fiber optic sensor 720. The barcode scanner 710 is located above the movement path of the second moving module 30, and the through-beam fiber optic sensor 720 is located on both sides of the second moving module 30.

[0046] Specifically, the barcode scanner 710 is fixedly mounted on the inner surface of the chassis body 10 and is positioned opposite to the ion air knife 60. At least two through-beam fiber optic sensors 720 are provided. In some embodiments, the two through-beam fiber optic sensors 720 are fixedly connected to the chassis body 10 respectively through fiber optic head fixing blocks. The two through-beam fiber optic sensors 720 are located on both sides of the second moving module 30 and are arranged obliquely opposite to each other.

[0047] To facilitate the use of the barcode scanning component 70, the barcode scanning component 70 also includes an optical fiber amplifier. The optical fiber amplifier is fixedly mounted on the equipment base plate near the second moving module 30. The optical fiber amplifier works in conjunction with the through-beam optical fiber sensor 720 to amplify and adjust the threshold of the fixture position signal detected by the through-beam optical fiber sensor.

[0048] In some embodiments, the barcode scanner 710 employs an industrial-grade QR code scanner with an adjustable mounting height to ensure optimal scanning distance. Specifically, the barcode scanner 710 can communicate in real time with the equipment control system and the MES (Manufacturing Execution System) to read product identification information when the fixture passes through the barcode scanning component 70 and upload the information to the equipment control system. After scanning, the data is immediately uploaded to the MES (Manufacturing Execution System) and compared with the system database. If the QR code is already bound to a rolling record, the equipment automatically stops, the fixture returns to the starting position, and an audible and visual alarm is triggered to prevent rework.

[0049] In some embodiments, the through-beam fiber optic sensor 720 is used to detect the actual height of the product surface. When the fixture carrying the product moves to the detection station, if the product floats due to not being placed in place, causing the optical path of the through-beam fiber optic sensor 720 to be blocked, the through-beam fiber optic sensor 720 will send a signal to the control system. The control system will then control the equipment to stop running and sound an alarm to ensure that only products with qualified positions can enter the subsequent rolling process.

[0050] In use, the battery automatic rolling equipment of this application, the fixture carrying the battery, driven by the second moving module 30, passes through the ion air knife 60, the barcode scanning component 70 and the rolling mechanism 50 in sequence. Through the motion linkage between the third moving module 40 and the first moving module 20, the rolling mechanism 50 is driven to press down to the appropriate position and roll the product, so as to realize the automated operation.

[0051] The complete processing procedure is as follows: First, the fixture moves to a position below the ion air knife 60, which generates a uniform ion airflow to neutralize static electricity and remove any adhering substances from the product and fixture surfaces. Next, the fixture enters the processing station of the barcode scanning component 70. The barcode scanner 710 reads the product identification information and binds it to the database. Simultaneously, the through-beam fiber optic sensor 720 verifies the product placement status, ensuring that only qualified products proceed to subsequent processes. Finally, the fixture reaches the processing station of the rolling mechanism 50. The rolling mechanism 50, through an integrated high-precision rolling sensor 540 and an elastic buffer component 530, applies and maintains a stable and controllable pressure on the battery, while simultaneously driving the roller 550 to reciprocate along a preset path, completing the precise pressing of the battery and casing. Through the spatial layout and coordinated control of multiple mechanisms, the equipment achieves fully automated integration of battery cleaning, information binding, and precision rolling, effectively avoiding secondary contamination and repetitive processing, and significantly improving production efficiency and product yield.

[0052] This automatic battery rolling equipment can achieve: (1) By setting the rolling mechanism 50 to perform the pressing operation between the battery and the casing, and combining it with three lead screw moving modules to realize the precise movement of the fixture and rollers that carry the battery products, the rollers 550 are driven to press down vertically, lift up and reciprocate horizontally, and the rolling path can be completed according to the preset, thus completing the precise pressing between the battery and the casing.

[0053] (2) By setting an elastic buffer component 530 to absorb impact and maintain pressure stability, and setting a rolling pressure sensor 540 to monitor the rolling pressure in real time, the rolling pressure can be adjusted in real time through the cooperation of the elastic buffer component 530 and the rolling pressure sensor 540. Therefore, the pressure control mechanism formed by the rolling pressure sensor 540 and the elastic buffer component 530 and the three lead screw moving modules constitute a closed-loop control, thereby realizing the precise adjustment and maintenance of dynamic pressure during the battery rolling process.

[0054] (3) Through the spatial layout and linkage control of multiple mechanisms, the equipment realizes the full-process automated assembly process integration of battery dust cleaning, information scanning and identification binding and precision rolling, effectively avoiding secondary pollution and repeated processing, and significantly improving production efficiency and product yield.

[0055] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this 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 these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
