Description

Technical Field

[0001] The utility model relates to the technical field of ball bonding machines, in particular to an auxiliary device for a ball bonding machine. Background Art

[0002] A ball bonder is a device used to manufacture microelectronic devices. Its working principle is to heat a metal wire (such as gold wire or aluminum wire) to a high temperature to form a ball at its end, and then bond the ball-shaped wire to the chip pin.

[0003] At present, before processing, the bonding machine usually needs to fix the workpiece on the base so that the bonding machine can weld it. When the workpiece is fixed, a positioning rod is usually inserted into the socket at the corresponding position of the workpiece to achieve positioning and clamping of the workpiece. This fixing method requires the staff to fix multiple points, which is cumbersome to operate and affects the processing efficiency of the bonding machine.

[0004] Therefore, it is necessary to design a ball bonding machine auxiliary device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A ball bonding machine auxiliary device includes a chassis 1, a processing chamber 11 provided on the chassis 1, and a base plate 2 provided in the processing chamber 11. A bonding arm 3 adapted to the base plate 2 is provided in the processing chamber 11. Four slide grooves 22 distributed in a ring array are provided on the base plate 2. A slider 23 is slidably installed in the slide groove 22. A push rod 231 is fixedly installed on the slider 23. A push plate 2311 is fixedly installed at one end of the push rod 231 away from the slider 23. A driving mechanism 4 is provided at one end of the base plate 2 away from the push plate 2311. The driving mechanism 4 can drive the slider 23 to slide along the slide groove 22, and then drive the push rod 231 and the push plate 2311, so that the four push plates 2311 can move synchronously, and the workpiece on the base plate 2 can be clamped and fixed.

[0022] Reference Figure 3 The driving mechanism 4 includes a transmission disc 41 rotatably mounted on the base disc 2, a servo motor 42 fixedly mounted on the base disc 2 through a bracket, and four adjusting rods 43 articulated on the transmission disc 41 and distributed in a ring array. The output end of the servo motor 42 is fixedly connected to the transmission disc 41, and a connecting rod 431 is rotatably mounted on the end of the adjusting rod 43 away from the transmission disc 41, and the end of the connecting rod 431 away from the adjusting rod 43 is fixedly connected to the slider 23. When the servo motor 42 is turned on, the transmission disc 41 can be driven to rotate. One end of the adjusting rod 43 is articulated with the transmission disc 41, and the other end is rotatably connected to the slider 23 through the connecting rod 431. Therefore, when the transmission disc 41 rotates, the slider 23 can be driven to slide in the slide groove 22 through the adjusting rod 43 to drive the slider 23.

[0023] Reference Figure 2 The base plate 2 is provided with a plurality of evenly distributed through holes 21, a connecting sleeve 5 is fixedly mounted on the base plate 2, an exhaust pipe 51 is fixedly mounted on one end of the connecting sleeve 5 away from the base plate 2, and an exhaust mechanism 52 is arranged in the exhaust pipe 51. The through holes 21 can connect one end of the base plate 2 with the connecting sleeve 5, so that the workpiece can be ventilated during the processing.

[0024] Reference Figure 2The exhaust mechanism 52 includes a mounting frame 521 fixedly mounted in the exhaust pipe 51, an exhaust fan 522 disposed in the mounting frame 521, and a filter screen 523 fixedly mounted at one end of the mounting frame 521. When the exhaust fan 522 is turned on, air can pass through the through hole 21 and enter the connecting sleeve 5, so that the workpiece can be cooled during welding, and the smoke generated during the processing can be discharged.

[0025] Reference Figure 2 The end of the connecting sleeve 5 away from the base plate 2 is set in a frustum shape. One end of the connecting sleeve 5 is set in a frustum shape to facilitate connection with the exhaust pipe 51 and facilitate assembly.

[0026] Reference Figure 1 The push plate 2311 is provided with anti-skid patterns on one side away from the push rod 231. The anti-skid patterns can ensure that the connection between the push plate 2311 and the workpiece is more stable, and avoid slipping during the processing.

[0027] The specific working principle of the utility model is as follows:

[0028] First, the cover of the processing chamber 11 can be opened and the workpiece can be fixed. When fixing, the workpiece can be placed at the center of the base plate 2, and then the servo motor 42 is turned on to drive the transmission plate 41 to rotate. One end of the adjustment rod 43 is hinged to the transmission plate 41, and the other end is rotatably connected to the slider 23 through the connecting rod 431. Therefore, when the transmission plate 41 rotates, it can drive the slider 23 to slide along the slide groove 22, and then drive the push rod 231 and the push plate 2311 to move to clamp and fix the workpiece. After the workpiece is fixed, the key arm 3 can be opened to adjust the workpiece. The workpiece is welded, and during the processing, the exhaust fan 522 is turned on to allow the air on the upper part of the base plate 2 to enter the connecting sleeve 5 through the through hole 21 and be discharged through the exhaust pipe 51. The air flow rate around the workpiece is increased, and the heat generated during the processing can be discharged, ensuring that the workpiece can be processed stably. After the processing is completed, the servo motor 42 can be reversed to loosen the workpiece, and the staff can take the material. The working principle and connection method of the bonding arm 3 and the exhaust fan 522 are all existing mature technologies and will not be described in detail here.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
