Description

Technical Field

[0001] This utility model relates to the technical field of chip carrier tape production equipment, specifically an ultrasonic deburring device for chip carrier tape production. Background Technology

[0002] In the chip carrier tape manufacturing process, burrs often exist on the carrier tape surface. These burrs not only affect the appearance quality of the carrier tape but can also adversely affect subsequent chip packaging processes, reducing chip production yield and reliability. Therefore, removing burrs from the carrier tape surface is a crucial step in chip carrier tape production. Traditional carrier tape deburring methods mainly include mechanical polishing and chemical etching. While mechanical polishing can remove some burrs, it easily damages the carrier tape surface, increasing surface roughness and potentially altering dimensional accuracy, thus affecting the carrier tape's performance. Moreover, mechanical polishing is inefficient and cannot meet the demands of large-scale production. Chemical etching, while removing burrs to some extent, uses large amounts of chemicals, which not only pollute the environment but may also harm the health of operators. Furthermore, the chemical etching process is difficult to control precisely, easily leading to over-etching of the carrier tape surface and affecting its quality.

[0003] With the continuous development of technology, ultrasonic technology has been increasingly applied to the field of deburring. However, existing ultrasonic deburring devices suffer from problems such as insufficient contact between the carrier and the processing liquid and uneven deburring effect when processing chip carriers. Furthermore, the processing liquid is often directly discharged after use, resulting in resource waste and increased production costs. In addition, some devices have low levels of automation, requiring frequent manual intervention, which not only increases labor intensity but also reduces production efficiency. Therefore, we propose an ultrasonic deburring device for chip carrier production. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic deburring device for chip carrier production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An ultrasonic deburring device for chip carrier tape production includes a processing box. A carrier tape roll is mounted on the upper right outer wall of the processing box via a mounting bracket. A take-up roller is mounted on the left outer wall of the processing box via a mounting bracket. An opening for the carrier tape to pass through is provided on the side wall of the processing box. Two guide rollers are rotatably mounted inside the processing box. An ultrasonic generator is also provided on the inner walls of the left and right sides of the processing box. A telescopic rod is also provided inside the processing box between the two guide rollers. A tension roller is mounted on the end of the telescopic arm of the telescopic rod via a fixing bracket. A return spring is sleeved on the outside of the telescopic rod. One end of the return spring contacts the lower inner wall of the processing box, and the other end of the return spring is connected to the fixing bracket.

[0007] As a further embodiment of this utility model, a sealing plate is also slidably provided on the top of the processing box.

[0008] As a further improvement of this utility model: a reflux chamber is also provided at the bottom of the inside of the processing box, and a filter screen is provided at the contact part between the reflux chamber and the processing box. A pump is also provided on the outer wall of the right side of the processing box. The inlet end of the pump is connected to the reflux chamber through the outlet pipe. The outlet end of the pump is provided with a reflux pipe. The outlet end of the reflux pipe passes through the sealing plate and extends into the inside of the processing box.

[0009] As a further improvement of this utility model, a handle is also provided on the top of the sealing plate.

[0010] As a further improvement of this utility model: a drive motor is also provided on the side wall of the mounting bracket on the left side, and the power output shaft of the drive motor is connected to the rotating shaft of the take-up roller through a coupling.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The device utilizes ultrasonic waves generated by an ultrasonic generator to induce cavitation, direct impact, and micro-jet effects in the liquid medium within the processing chamber. This effectively impacts and removes burrs from the carrier tape surface. Simultaneously, the guide rollers and tension rollers installed within the processing chamber ensure full contact between the carrier tape and the processing liquid. Combined with the adaptively adjustable tension rollers, this guarantees uniform deburring, improves deburring quality, and meets the high-precision requirements of chip carrier tape production.

[0013] 2. The return chamber and filter screen installed at the bottom of the treatment tank can filter out burrs in the treatment liquid.

[0019] Example

[0020] Please see Figures 1-3 In this embodiment of the present invention, an ultrasonic deburring device for chip carrier tape production includes a processing box 1. A carrier tape roll 3 is mounted on the upper right outer wall of the processing box 1 via a mounting frame 2. A take-up roller 4 is mounted on the left outer wall of the processing box 1 via a mounting frame 2. The take-up roller 4 can be used to recycle the processed carrier tape, thereby reducing the workload of subsequent carrier tape recycling and enabling the device to achieve automated carrier tape deburring. A drive motor 5 is also mounted on the side wall of the left mounting frame 2. The power output shaft of the drive motor 5 is connected to the rotation shaft of the take-up roller 4 via a coupling. At this time, the drive motor 5 can drive the take-up roller 4 to rotate, thereby facilitating the winding of the processed carrier tape. An opening for the carrier tape to pass through is provided on the side wall of the processing box 1.

[0021] Inside the processing chamber 1, two guide rollers 7 are rotatably installed on the left and right sides. Under the action of the guide rollers 7, the carrier belt can make more sufficient contact with the liquid inside the processing chamber 1. Ultrasonic generators 16 are also installed on the inner walls of the left and right sides of the processing chamber 1. Under the action of the ultrasonic generators 16, ultrasonic waves can be generated. The cavitation effect, direct impact effect, and micro-jet effect generated by the ultrasonic waves in the liquid medium, when the ultrasonic transducer converts high-frequency electrical energy into mechanical vibration energy and transmits it to the liquid medium (such as water or special solutions), a large number of tiny bubbles are generated inside the liquid and rapidly expand and burst. The powerful energy released in this process is sufficient to impact and peel off the burrs on the surface of the workpiece. Inside the treatment box 1, between the two guide rollers 7, there is a telescopic rod 8. The end of the telescopic arm of the telescopic rod 8 is connected to a tension roller 9 via a fixed frame. Under the action of the tension roller 9, the carrier belt can be tensioned, so that the carrier belt can better contact the liquid inside the treatment box 1, thereby ensuring the quality of deburring the carrier belt. A return spring 10 is sleeved on the outside of the telescopic rod 8. One end of the return spring 10 contacts the lower inner wall of the treatment box 1, and the other end of the return spring 10 is connected to the fixed frame. At this time, under the action of the return spring 10, the height of the tension roller 9 can be adjusted, thus allowing it to adapt to changes, thereby ensuring the quality and efficiency of deburring the carrier belt surface.

[0022] A sealing plate 6 is slidably installed on the top of the treatment box 1. The sealing plate 6 ensures the airtightness of the treatment box 1 during actual use, thereby reducing the possibility of internal liquid leakage. A handle 601 is also provided on the top of the sealing plate 6, allowing it to be removed for cleaning of the inside of the treatment box 1, thus ensuring the efficiency of its use. A return chamber 11 is also provided at the bottom inside the treatment box 1. A filter screen 12 is installed at the contact point between the return chamber 11 and the treatment box 1. The filter screen 12 helps to filter out... The burrs in the liquid are filtered out. A pump 14 is also installed on the outer right side of the treatment tank 1. The inlet end of the pump 14 is connected to the return chamber 11 through the outlet pipe 13. The outlet end of the pump 14 is provided with a return pipe 15. The outlet end of the return pipe 15 passes through the sealing plate 6 and extends into the interior of the treatment tank 1. In actual use, the liquid water used to treat the burrs is filtered by the filter screen plate 12. Then, the filtered liquid is returned to the interior of the treatment tank 1 through the pump 14 and the return pipe 15, thereby realizing the reuse of the liquid.

[0023] In actual use, the carrier tape is released from the carrier tape roll 3 set by the mounting bracket 2 above the right outer wall of the treatment box 1. The carrier tape enters the interior of the treatment box 1 through the opening and passes around the two guide rollers 7 inside the treatment box 1. The guide rollers 7 ensure that the carrier tape is in full contact with the treatment liquid inside the treatment box 1. The ultrasonic generator 16 on the inner wall of the left and right sides of the treatment box 1 generates ultrasonic waves. The ultrasonic transducer converts high-frequency electrical energy into mechanical vibration energy and transmits it to the liquid medium. A large number of tiny bubbles are generated inside the liquid and rapidly expand and burst. The cavitation effect, direct impact effect and micro-jet effect are used to impact and peel off the burrs on the surface of the carrier tape. The telescopic rod 8 located between the two guide rollers 7 inside the treatment box 1 has a tension roller 9 set at the end of its telescopic arm through the fixing bracket. The tension roller 9 tensions the carrier tape, allowing the carrier tape to better contact the treatment liquid and ensuring the quality of deburring. A return spring 10, sleeved on the outside of the telescopic rod 8, contacts the inner wall below the processing tank 1 at one end and connects to the fixed frame at the other end, allowing the height of the tension roller 9 to be adjusted to adapt to changes in the carrier belt, ensuring deburring quality and efficiency. The drive motor 5 is connected to the rotating shaft of the take-up roller 4 via a coupling, driving the take-up roller 4 to rotate and retract the processed carrier belt, realizing automated deburring. A sealing plate 6, slidably mounted on the top of the processing tank 1, ensures the device's airtightness and reduces internal liquid outflow. A handle 601 on its top facilitates the removal of the sealing plate 6 for cleaning the inside of the processing tank 1. A filter screen 12 is installed at the contact point between the return chamber 11 at the bottom of the processing tank 1 and the processing tank 1 to filter out burrs from the liquid. The inlet end of the pump 14 is connected to the return chamber 11 via an outlet pipe 13. A return pipe 15 is installed at the outlet end, extending through the sealing plate 6 into the processing tank 1, enabling the reuse of filtered liquid and improving resource utilization.
