Description

A laser edge cutting and shaping machine for arc-shaped irregular batteries Technical Field

[0001] This utility model relates to the field of lithium battery production equipment technology, and in particular to a cutting and shaping machine for arc-shaped irregular batteries. Background Technology

[0002] Some electronic products, such as some smartwatches, use curved, irregularly shaped batteries due to their structural requirements. Compared to square or round batteries, curved batteries are more difficult to manufacture due to their unevenness. For example, the traditional method for trimming and shaping curved batteries involves using metal cutting tools to cut the edges first, followed by shaping using bending machines or other forming mechanisms. However, this method not only results in poor trimming accuracy and the potential presence of powder after trimming, affecting product performance and appearance, but also requires multiple machines to be combined into a production line. The limited number of automated integrated lines leads to low production efficiency and high production costs, making it difficult to meet the current demands for high-precision, automated, integrated, and high-volume production of curved, irregularly shaped batteries. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a laser cutting and shaping machine for curved irregularly shaped batteries, which features a more rational process structure, higher automation, higher production efficiency, more concentrated functions, and better cutting effect.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a laser edge cutting and shaping machine for arc-shaped irregular batteries, including a main body, a feeding mechanism, a CCD positioning mechanism, a unloading mechanism, and a rejection mechanism. The main body has an electronic control system and a drive mechanism. A turntable is installed on the main body and connected to the drive mechanism. The CCD positioning mechanism is located next to the turntable and close to the feeding mechanism. The feeding mechanism and the unloading mechanism are located close to the turntable. Several fixtures for placing arc-shaped batteries are provided on the turntable. A laser edge cutting mechanism, a glue dispensing mechanism, a folding mechanism, and a hot-pressing mechanism are arranged sequentially around the edge of the turntable. The laser edge cutting mechanism is located at the next station after the CCD positioning mechanism, and the hot-pressing mechanism is located at the previous station after the unloading mechanism. The folding mechanism includes a heating element connected to a heating tube. The bottom of the heating element has a downward-extending folding head. The folding operation of the arc-shaped battery is achieved by the heating element moving downward with the folding head.

[0005] Furthermore, the laser cutting mechanism has a laser cutting head connected to the laser cutting host, which is mounted on the main body via a support column. A screw is installed on the support column, and the laser cutting host is connected to the screw via a nut. A rocker wheel is installed at the top of the screw. A waste box is installed below the laser cutting head, and the waste box is installed on the main body and located next to the cutting station.

[0006] Furthermore, the dispensing host of the dispensing mechanism is mounted on the host body, and the dispensing head of the dispensing mechanism is mounted on the dispensing host through a dispensing cylinder to form a structure that can perform lifting and lowering movements.

[0007] Furthermore, the heating element is connected to a drive cylinder to form a structure capable of lifting and lowering. The drive cylinder is mounted on a mounting bracket, which is mounted on the main body.

[0008] Furthermore, a rotating shaft is mounted on the main body of the fixture via bearings. A rotary motor is connected to the tail end of the rotating shaft, and an eccentrically mounted mounting arm is fixed to the front end. A lifting cylinder is mounted on the mounting arm, and a fixed head is connected to the lifting cylinder. The fixed head is connected to a support arm whose shape matches the arc-shaped battery, and the arc-shaped battery is placed on the support arm.

[0009] Furthermore, the support arm is equipped with adsorption holes and connected to a vacuum pumping device, allowing the arc-shaped battery to be adsorbed onto the support arm through the adsorption holes.

[0010] Preferably, the drive mechanism uses a servo motor to drive the turntable to rotate.

[0011] Furthermore, a weighing mechanism is set up between the dispensing mechanism and the folding mechanism as a weighing station, and a rejection mechanism for products that fail to meet the weighing requirements is set up next to the weighing mechanism.

[0012] Furthermore, a precision slip ring is set at the center of the turntable. The precision slip ring is connected to the electronic control system, and multiple adapters for connecting each cylinder and each motor are set on the side wall of the precision slip ring.

[0013] The hot-edge mechanism has the same structure as the folding mechanism, the only difference being that the hot-edge mechanism is used to hot-edge the folded edge of the arc-shaped battery.

[0014] This invention integrates existing laser cutting, dispensing, folding (heating), and CCD positioning mechanisms into a single machine. Through a rational process design, it forms a structure for continuous operation around a turntable. This allows for the high-precision cutting, dispensing, folding, and heat-pressing of curved batteries, resulting in a high degree of automation, significantly improving production efficiency, reducing production costs, and improving the cutting effect of the batteries. Furthermore, a precision slip ring is installed in the center of the turntable for electrical connections between motors and cylinders, making the entire machine cleaner, more organized, less prone to failure, and more reliable.

Detailed Implementation

[0022] In this embodiment, referring to Figures 1-6, the laser edge-cutting and shaping machine for arc-shaped irregular batteries includes a main body 1, a feeding mechanism 2, a CCD positioning mechanism 3, a discharging mechanism 9, and a rejection mechanism 10. The main body 1 contains an electronic control system and a drive mechanism. A turntable 11 is mounted on the main body 1 and connected to the drive mechanism. The CCD positioning mechanism 3 is located next to the turntable 11 and close to the feeding mechanism 2. The feeding mechanism 2 and the discharging mechanism 9 are located close to the turntable 11 and are used to achieve automatic feeding and automatic discharging, respectively. The turntable 11 is provided with several mounting points for placing arc-shaped batteries A. Fixture 12; around the edge of turntable 11, a laser cutting mechanism 4, a dispensing mechanism 5, a folding mechanism 7, and a heating mechanism 8 are arranged in sequence. The laser cutting mechanism 4 is located at the next station after the CCD positioning mechanism 3, and the heating mechanism 8 is located at the previous station after the unloading mechanism 9. The folding mechanism 7 includes a heating body 73, which is connected to a heating tube 74. The bottom of the heating body 73 is provided with a downward-extending folding head 75. The heating body 73 moves the folding head 75 downward together, and the folding head 75 presses down on the edge of the arc-shaped battery A. The folding is achieved with the cooperation of fixture 12.

[0023] The laser cutting mechanism 4 has a laser cutting host 41 connected to a laser cutting head 42. The laser cutting host 42 is mounted on the main body 1 via a support column 43. A screw is provided on the support column 43. The laser cutting host 41 is connected to the screw via a nut. A rocker wheel 44 is provided at the top of the screw. The laser cutting host 41 can be driven to rise or fall by rotating the rocker wheel 44. A waste box 14 is provided below the laser cutting head 42. The waste box 14 is mounted on the main body 1 and located next to the cutting station. It is used to receive the cut waste.

[0024] The dispensing host 51 of the dispensing mechanism 5 is installed on the host body 1. The dispensing head 52 of the dispensing mechanism 5 is installed on the dispensing host 51 through a dispensing cylinder 53 to form a structure that can move up and down. The dispensing head 52 is driven by the dispensing cylinder 53 to descend and dispense glue to the edge of the arc-shaped battery A that has been cut off.

[0025] The heating element 73 is connected to a drive cylinder 72 to form a structure that can perform lifting and lowering movements. The drive cylinder 72 is mounted on a mounting bracket 71, which is mounted on the main body 1.

[0026] A rotating shaft 123 is mounted on the main body 121 of the fixture 12 via bearings. A rotating motor 122 is connected to the tail end of the rotating shaft 123, and an eccentrically mounted mounting arm 124 is fixed to the front end. A lifting cylinder 125 is mounted on the mounting arm 124. The lifting cylinder 125 is connected to a fixing head 126. The fixing head 126 is connected to a support arm 127 whose shape matches the arc-shaped battery A. The arc-shaped battery A is placed on the support arm 127.

[0027] During edge trimming, the rotary motor 122 drives the rotating shaft 123 to rotate, causing the arc-shaped battery A to rotate around the shaft, thus completing the edge trimming operation in conjunction with the laser trimming head 42. During edge folding, the folding head 75 moves downward along the edge of the support arm 127, thereby bending the outwardly protruding edge of the arc-shaped battery A downward. The lifting cylinder 125 drives the fixing head 126 to rise, causing the support arm 127 to rise along with the arc-shaped battery A above the mounting arm 124, thus achieving clearance to facilitate the folding of the other side of the arc-shaped battery A. In addition, the entire fixture 12 can achieve fine-tuning of horizontal displacement.

[0028] The support arm 127 is provided with adsorption holes and is connected to a vacuum device. The arc-shaped battery A is adsorbed onto the support arm 127 through the adsorption holes.

[0029] The drive mechanism uses a servo motor to drive the turntable 11 to rotate.

[0030] A weighing mechanism 6 is set between the dispensing mechanism 5 and the folding mechanism 7 as a weighing station, and a rejection mechanism 10 for products that fail to meet the weighing requirements is set next to the weighing mechanism 6.

[0031] A precision slip ring 13 is located at the center of the turntable 11. The precision slip ring 13 is connected to the electronic control system. Multiple adapters for connecting each cylinder and each motor are provided on the side wall of the precision slip ring 13. This takes advantage of the centralized adapters of the precision slip ring 13, avoiding the messy arrangement of various cables.

[0032] In addition, the hot edge mechanism 8 has the same structure and operation process as the folding mechanism 7. The only difference is that the hot edge mechanism 8 hot edges the folded edge of the arc-shaped battery A.

[0033] Work process: The manual places the entire stack of material trays in the loading area. The robotic arm of the loading mechanism 2 picks up and places the arc-shaped battery A into fixture 12. The CCD positioning mechanism 3 takes pictures and corrects the position. The laser cutting mechanism 4 cuts off the excess two sides of the arc-shaped battery A. Weighing (optional station) is performed. The glue dispensing mechanism 5 applies glue to the two sides of the arc-shaped battery A that have been cut off. CCD glue dispensing inspection (NG products are discharged through rejection mechanism 10). The two sides of the arc-shaped battery A are folded by the folding mechanism 7. The two sides of the arc-shaped battery A are heated by the heating mechanism 8. The battery is weighed after scanning the code (NG products are discharged, and a barcode scanning and weighing mechanism can be added). The robotic arm of the unloading mechanism 9 picks up the material and places it on a tray. The manual removes the entire stack of material trays.

[0034] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
