[0002] Battery chips are a key component of batteries, primarily used to monitor, control, and protect them, ensuring battery safety and stable performance. During the manufacturing process, battery chips require wire bonding, typically using a wire bonding machine. To prevent dust from falling onto the bonding surfaces of the battery chips, protective covers are usually installed on the bonding workbench.

[0003] In related technologies, protective covers typically enclose both the wire bonding machine and the chip. When the chip needs to be replaced, the protective cover must be opened and closed manually or a separate drive structure must be used to control the opening and closing of the protective cover in order to replace the chip. The opening efficiency of the protective cover is low, which reduces the chip replacement efficiency. Furthermore, during the opening and closing process, dust adhering to the protective cover is easily dropped onto the chip, reducing the effectiveness of the protective cover. Based on this, this application proposes a protective cover for a wire bonding machine. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a protective cover for a chip wire bonding machine. Addressing the problem of low opening and closing efficiency, this application designs the protective cover and the welding structure of the chip wire bonding machine to be linked. When the welding structure of the chip wire bonding machine moves, it can drive the protective cover to move, achieving simultaneous movement of the welding structure and the protective cover, thereby improving the opening and closing speed of the protective cover. Specifically, the protective cover for a chip wire bonding machine proposed in this application includes two parts: a fixed part 1 and a moving part 7. A telescopic tube 18 is fixedly connected to the middle of the top of the moving part 7, and a fixing ring 10 is fixedly connected to the other end of the telescopic tube 18. During use, the fixing ring 10 and the welding structure of the chip wire bonding machine are connected. The protective cover can protect the welding structure of the chip wire bonding machine, and when the chip is replaced, the welding structure of the chip wire bonding machine can drive the protective cover to move, achieving simultaneous movement of the welding structure and the protective cover, thus improving the opening and closing speed of the protective cover. By setting the telescopic tube 18, the distance between the fixing ring 10 and the moving part 7 can be changed, facilitating the lifting and lowering of the chip wire bonding machine.

[0024] The bottom of the movable part 7 is fixedly connected to a fixed frame 8, and the top of the fixed part 1 is fixedly connected to a fixed frame 3. The top of the fixed frame 3 is at the same height as the bottom of the fixed frame 8. An electromagnet 211 is provided on the side wall of the fixed frame 23. When the electromagnet 211 is energized, it is magnetically attracted to the fixed frame 8. With the electromagnet 211 energized, the movable part 7 and the fixed part 1 form a whole. When the welding structure of the chip wire bonding machine moves, it can drive the movable part 7 and the fixed part 1 to move simultaneously. When the electromagnet 211 is de-energized, the movable part 7 and the fixed part 1 are in contact. When the welding structure of the chip wire bonding machine moves, it can only drive the movable part 7 to move, which facilitates the chip wire bonding machine to weld different parts of the battery chip.

[0025] In order to protect the chip even when the moving part 7 and the fixed part 1 are misaligned, this application provides a sealing structure 4 on the outer sides of the two adjacent sides of the fixed frame 3, and uses the sealing structure 4 to seal the gap when the moving part 7 and the fixed part 1 are misaligned.

[0026] In some embodiments of this application, the sealing structure 4 includes an automatic winding structure. The automatic winding structure includes a housing 12, a central rod 17 is movably connected to the center of the inner cavity of the housing 12, a coil spring 16 is provided on the outer ring of the central rod 17, one end of the coil spring 16 is fixedly connected to the central rod 17, and the other end of the coil spring 16 is fixedly connected to the sealing strip 15. The sealing strip 15 is wound around the coil spring 16. The housing 12 has a slot on the side near the moving part 7. The other end of the sealing strip 15 extends to the outside of the housing 12 through the slot. The sealing strip 15 is movably connected to the inner cavity of the slot. With the automatic winding structure, the length of the sealing strip 15 exposed to the outside can be changed under the action of external force, thus releasing the restriction on the sealing strip 15. Under the action of the rebound force of the coil spring 16, the sealing strip 15 can be rewound onto the coil spring 16, realizing the automatic storage of the sealing strip 15.

[0027] The other end of the sealing strip 15 is fixedly connected to the connecting plate 14. When the electromagnet 9 is energized, the electromagnet 9 and the connecting plate 14 in contact with it are magnetically attracted. The bottom of the other end of the sealing strip 15, the bottom of the connecting plate 14, the bottom of the fixed frame 8, and the top of the fixed frame 3 are at the same height. When the moving part 7 moves in the direction of the connecting plate 14, the moving part 7 can drive the connecting plate 14 to move through the electromagnet 9. The connecting plate 14 drives the sealing strip 15 to move. The sealing strip 15 can be used to cover the gap between the moving part 7 and the fixed part 1.

[0028] A dust-sweeping strip is fixedly connected to the outside of the groove. The dust-sweeping strip can be used to clean the dust that falls on the sealing strip 15. The dust-sweeping strip can be a cleaning brush. The inside of the groove is provided with rounded corners to reduce the friction between the sealing strip 15 and the groove.

[0029] The connecting plate 14 is located between the electromagnet 9 and the automatic winding structure. A pressure sensor 13 is fixed on the side of the automatic winding structure near the connecting plate 14. The pressure sensor 13 can be used to detect the distance between the connecting plate 14 and the automatic winding structure, thereby determining whether the dust between the connecting plate 14 and the automatic winding structure needs to be cleaned or whether the coil spring 16 has failed.

[0030] The bottom of the fixed part 1 is fixedly connected to a counterweight frame 2. By setting the counterweight frame 2, the center of gravity of the fixed part 1 is lowered, which can improve the stability of the fixed part 1. The bottom of the counterweight frame 2 is fixedly connected to a sealing gasket. The sealing gasket material can be rubber. The sealing gasket is used to reduce the impact force when the fixed part 1 contacts the welding workbench.

[0031] To address the issue of dust easily falling onto the chip during the opening and closing of the protective cover, this application includes a baffle 6 fixedly connected to the outer ring of the counterweight frame 2. The baffle 6, the counterweight frame 2, and the fixing part 1 form a dust collection chamber. The sealing structure 4 and the fixing frame 3 are both located above the dust collection chamber. The outer surface of the baffle 6 is provided with an anti-stick coating. During the opening and closing of the protective cover, the dust falling from the protective cover can be collected using the dust collection chamber.

[0032] The connecting plate 14 and the fixed frame 1 8 can both be made of metal iron. By setting the fixed frame 1 8 and the fixed frame 2 3, the overlapping area of ​​the fixed part 1 and the moving part 7 can be increased, thereby increasing the moving range of the chip wire bonding machine welding structure.

[0033] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0034] In summary: When using this protective cover for the chip wire bonding machine, the welding structure of the chip wire bonding machine is inserted into the inner cavity of the protective cover through the inner cavities of both the fixing ring 10 and the telescopic tube 18. Operators use bolts or other tools to fix the fixing ring 10 and the welding structure of the chip wire bonding machine together. When the protective cover needs to be opened or closed, the electromagnet 11 is energized. The electromagnet 11 is magnetically attracted to the fixed frame 8. Under the action of this attraction, the movement of the welding structure of the chip wire bonding machine drives the movement of the protective cover, achieving the purpose of synchronous opening and closing of the welding structure of the chip wire bonding machine and the protective cover, thus improving the opening and closing efficiency of the protective cover.

[0035] During the wire bonding process, electromagnet 11 is de-energized, and the battery chip with the wire bonded is covered by the protective cover. When the wire bonding machine needs to bond multiple parts on the chip that are on the same straight line, electromagnet 9 on that straight line is energized. Electromagnet 9 and the connecting plate 14 in contact with it are magnetically attracted. As the wire bonding machine moves the moving part 7, the moving part 7 pulls the sealing strip 15 through the connecting plate 14, increasing the exposed length of the sealing strip 15. The sealing strip 15 can be used to offset the gap between the moving part 7 and the fixed part 1. When the welding structure of the chip wire bonding machine needs to weld other parts on the chip, and the distance between the welding structure of the chip wire bonding machine and the part to be welded is greater than the width of the overlapping part of the fixed frame 1 8 and the fixed frame 2 3, that is, when the welding structure of the chip wire bonding machine moves to the part to be welded, a misalignment will be generated between the fixed part 1 and the moving part 7, and the sealing strip 15 cannot cover the misalignment. Then the welding structure of the chip wire bonding machine will drive the entire protective cover to move until the welding structure of the chip wire bonding machine and the part to be welded are on the same straight line. At this time, the protective cover can still protect the chip.
