Description

Technical Field

[0001] The invention relates to the technical field of semiconductor manufacturing, and in particular to a laser debonding device for plastic packaged parts. Background Art

[0002] Laser debonding equipment for plastic encapsulated parts is a device that uses laser to remove the overflow glue caused by the compression molding method in the encapsulation process of plastic encapsulated parts. At present, the automatic debonding equipment for plastic encapsulated parts at home and abroad generally places the plastic encapsulated parts to be debonded on a conveyor line for positioning, the plastic encapsulated parts are fixed, and the laser moves to the plastic encapsulated parts to debond, such as the patent with publication number CN116017865A. The problem with this debonding method is that the debonding accuracy is poor and the application range is small. It can only be applied to the debonding of plastic encapsulated parts with uniform glue thickness. If the thickness of the overflow glue to be removed on the surface of the plastic encapsulated parts is uneven, it cannot be applied, and even causes the problem of excessive debonding. Summary of the invention

[0003] The main purpose of the present invention is to provide a laser debonding device for plastic packaged parts, aiming to solve the problems of poor debonding accuracy and small application range of the existing laser debonding devices for plastic packaged parts.

[0004] In order to solve the above problems, the present invention proposes a plastic package laser debonding device, comprising a machine platform and a loading basket conveying station, a loading product transfer station, a laser debonding station, a unloading product transfer station and an unloading basket conveying station arranged on the machine platform;

[0005] The loading basket conveying station includes a conveyor line 1, a conveyor line 2, a basket lifting device and a material pushing mechanism 1. The material pushing mechanism 1 is located above the conveyor line 1, the conveyor line 2 is located above the material pushing mechanism 1 and is parallel to the conveyor line 1. The basket lifting device is located on the same side of the conveyor line 1, the conveyor line 2 and the material pushing mechanism 1. The basket containing plastic-sealed parts conveyed by the conveyor line 2 is clamped by the basket lifting device and driven to descend. The material pushing mechanism 1 pushes out the plastic-sealed parts in the basket one by one. When there are no plastic-sealed parts in the basket, the basket lifting device places the empty basket on the conveyor line 1 and sends it away.

[0006] The loading product transfer station includes a three-axis material picking component 1 and a conveyor line 3. The pushing mechanism 1 pushes the plastic-sealed parts in the basket onto the conveyor line 3, and the conveyor line 3 conveys the plastic-sealed parts to the material picking position. Then, the three-axis material picking component 1 goes to the material picking position to take away the plastic-sealed parts.

[0007] The laser degumming station includes a translation device four and a mounting frame four, on which a translation device five, a visual camera, and a laser are mounted, and on which a three-dimensional laser line scanner and an ion wind knife one are mounted. The translation action direction of the translation device five is perpendicular to the translation action direction of the translation device four, and on which a rotating module two is mounted, and the rotating module two is connected to a mounting plate four, and on which a dust box and a rotating module three are mounted, and the rotating module three is located directly above the dust box, and a positioning fixture is mounted on the upper end of the rotating module three, and the positioning fixture is driven to rotate around a vertical axis by the rotating module three. The rotating module 2 is used to drive the mounting plate 4 to rotate around the horizontal axis. After the three-axis material picking component 1 places the plastic package on the positioning fixture, the translation device 4 drives the plastic package to pass directly under the visual camera, the three-dimensional laser line scanner, and the ion wind knife 1, and enter the laser for laser debonding. The plastic package first comes directly under the ion wind knife 1, and the ion wind knife 1 cleans the surface of the plastic package. Then the plastic package comes directly under the visual camera, and the debonding range is visually calibrated by the visual camera. Then the plastic package comes directly under the three-dimensional laser line scanner, and the debonding thickness is confirmed by the three-dimensional laser line scanner, and finally enters the laser.

[0008] The unloading product transfer station includes a three-axis material picking component 2, a conveyor, a dust removal device and a pusher mechanism 2. The three-axis material picking component 2 transfers the plastic-sealed parts on the positioning fixture after laser debonding to the dust removal device, and the dust removal device removes dust from the plastic-sealed parts. The plastic-sealed parts after dust removal are transferred to the conveyor by the three-axis material picking component 2. The conveyor drives the plastic-sealed parts to move closer to the unloading basket conveying station. When the plastic-sealed parts move to the end of the conveyor, the pusher mechanism 2 pushes the plastic-sealed parts into the empty basket in the unloading basket conveying station. After the basket is full of plastic-sealed parts, the unloading basket conveying station sends the basket away.

[0069] The present invention proposes a laser degumming device for plastic-sealed parts. The laser degumming device for plastic-sealed parts adopts a basket 214 to load plastic-sealed parts 7 products, which is beneficial to improving the laser degumming efficiency of plastic-sealed parts 7. Before laser degumming, the plastic-sealed parts 7 products must be visually calibrated by a visual camera 412 to determine the degumming range and confirmed by a three-dimensional laser line scanner 49 to enable a laser 413 to accurately remove excess overflow glue of different thicknesses. The degumming device has high degumming accuracy and a wide range of applications. It can be applied to degumming of various different types of plastic-sealed parts 7 products and is not affected by the thickness of the overflow glue. It is very suitable for degumming operations of plastic-sealed parts 7 products with uneven thickness of the overflow glue.

[0070] Specifically, in one embodiment of the invention, Figure 1 As shown, the plastic-encapsulated parts laser debonding equipment includes a machine platform 1 and a loading basket conveying station 2, a loading product transfer station 3, a laser debonding station 4, a unloading product transfer station 5 and a unloading basket conveying station 6 arranged on the machine platform 1.

[0071] Specifically, Figure 2-Figure 7 As shown, the loading basket conveying station 2 includes a conveyor line 1 211, a conveyor line 212, a basket lifting device and a pushing mechanism 1. The pushing mechanism 1 is located above the conveyor line 1 211, the conveyor line 212 is located above the pushing mechanism 1 and is parallel to the conveyor line 1 211, the basket lifting device is located on the same side of the conveyor line 1 211, the conveyor line 212 and the pushing mechanism 1. The basket 214 containing the plastic-sealed parts 7 conveyed by the conveyor line 212 is clamped by the basket lifting device and drives the basket 214 to descend, the pushing mechanism 1 pushes out the plastic-sealed parts 7 in the basket 214 one by one, and when there are no plastic-sealed parts 7 in the basket 214, the basket lifting device places the empty basket 214 on the conveyor line 1 211 and sends it away.

[0072] In this embodiment, if Figure 6As shown, the basket lifting device includes: a translation device 22, a lifting device 23, a mounting plate 24, and a motor 28. The translation direction of the translation device 22 is parallel to the conveyor line 211 and the conveyor line 212. With this design, the upper clamping block 27 and the lower clamping arm 25 can be driven by the translation device 22 to approach the conveyor line 211 and the conveyor line 212, so as to facilitate the removal of the basket 214 from the conveyor line 212 and the placement of the basket 214 on the conveyor line 211; the lifting device 23 is arranged on the translation device 22, and the translation device 22 drives the lifting device 23 to translate; the mounting plate 24 is connected to the lifting device 23, and the lifting device 23 drives the mounting plate 24 to lift The lower end of the mounting plate 1 24 is fixedly mounted with a lower clamping arm 25, and an upper clamping block 27 is arranged above the lower clamping arm 25, and the upper clamping block 27 is connected to the lifting device 2 26, and the lifting device 26 is fixedly connected to the mounting plate 1 24. The upper clamping block 27 and the lower clamping arm 25 are driven by the translation device 1 22 and the lifting device 1 23 to move to the upper and lower ends of the basket 214 containing the plastic-sealed part 7 transported by the conveyor line 2 212, and then the lifting device 2 26 drives the upper clamping block 27 to descend and cooperates with the lower clamping arm 25 to clamp and fix the basket 214, and the basket 214 containing the plastic-sealed part 7 can be placed at the starting end of the conveyor line 2 212 by the robot, and then the conveyor line 212 is started to transport the basket 214 to the end, as shown in FIG. Figure 2 and Figure 3 As shown, the end of the conveyor line 212 is close to the basket lifting device. After the basket 214 is conveyed to the end of the conveyor line 212, the upper clamping block 27 and the lower clamping arm 25 are moved to the upper and lower ends of the basket 214 under the drive of the translation device 1 22 and the lifting device 1 23, and then the lifting device 26 drives the upper clamping block 27 to descend and cooperate with the lower clamping arm 25 to clamp and fix the basket 214, thereby completing the action of removing the basket 214 from the conveyor line 212.

[0073] In this embodiment, if Figure 6 As shown, the motor 28 is vertically fixedly mounted on the mounting plate 24, and a cylindrical rotating block 29 is coaxially fixedly mounted on the lower end of the output shaft of the motor 28. A pair of pins 210 are centrally symmetrically arranged on the lower surface of the rotating block 29, as shown in FIG. Figure 3 and Figure 4As shown, both ends of the basket 214 are open, and the inner wall of the basket 214 is provided with a plurality of mounting grooves 215 from top to bottom, and both ends of the mounting grooves 215 extend to the open ends of the basket 214, and a plastic sealing component 7 is slidably inserted and installed in each mounting groove 215, and the plastic sealing component 7 slides in and out of the mounting grooves 215 from both ends of the basket 214, so as to enter and exit the basket 214, and the upper surfaces of both ends of the basket 214 are provided with receiving grooves 216 for accommodating the rotating block 29, and a rotating arm 217 is rotatably installed in the receiving groove 216, and a blocking rod 218 is fixedly connected to the far end of the rotating arm 217, and the blocking rod 218 is located at the open ends of the basket 214, and the blocking rod 218 is used to block the plastic sealing component 7 from entering and exiting the basket 214, so as to prevent the plastic sealing component 7 from sliding out of the mounting grooves. The slot 215 falls off. In the process that the translation device 22 drives the upper clamping block 27 and the lower clamping arm 25 to translate to the upper and lower ends of the basket 214, the rotating block 29 translates and slides into the accommodating slot 216, and a pair of pin shafts 210 are respectively arranged on both sides of the rotating arm 217. With this design, after the motor 28 is started, it drives the rotating block 29 to rotate. Through the pair of pin shafts 210, the rotating arm 217 is rotated to drive the blocking rod 218 to rotate and leave the opening of the basket 214 so that the plastic sealing part 7 can enter and exit the basket 214. Therefore, after the upper clamping block 27 and the lower clamping arm 25 clamp the basket 214, it is necessary to control the motor 28 to drive the blocking rod 218 to rotate and leave the opening of the basket 214, and then the pushing mechanism 1 can push the plastic sealing part 7 out of the basket 214.

[0074] In this embodiment, if Figure 5 and Figure 7As shown, the push mechanism 1 includes: a mounting frame 1 219, a translation device 3 222, a spring 1 226, and an in-position sensor 228. A slide plate 221 is horizontally slidably installed on the mounting frame 1 219, and the sliding direction of the slide plate 221 is the same as the translation direction of the translation device 1 22. This design facilitates the push mechanism 1 to push the ejector rod 223 to the ejection position, and then the translation device 3 222 pushes the ejector rod 223 to push the plastic package 7 out of the basket 214 at the ejection position. After the pushing is completed, the translation device 1 22 and the translation device 3 22 2 drives the push rod 223 to reset. This design does not affect the lifting of the basket 214. The installation plate 1 24 is fixedly installed with a second translation device 220, and the second translation device 220 is connected to the slide plate 1 221. The slide plate 1 221 is driven to slide through the second translation device 220; the translation device 3 222 is connected to the slide plate 1 221 through a slide rail 1 227 for horizontal sliding, and the sliding direction is perpendicular to the translation direction of the translation device 1 22. The slide plate 1 221 is horizontally slidably installed with a push rod 223, and the push rod 223 is connected to the slide plate 1 221 through a connecting piece 224. The first spring 226 is connected to the translation device 3 222. In addition, the spring 1 226 extends along the sliding direction of the translation device 3 222. The two ends of the spring 1 226 are respectively connected to the translation device 3 222 and the slide plate 1 221 through the second pin 225. When the basket lifting device drives the basket 214 to descend until the push rod 223 is flush with the plastic sealing part 7, the basket 214 stops descending, and then the translation device 220 pushes the push rod 223 to the top material position, and then the translation device 3 222 pushes the push rod 223 to translate at the top material position to push the plastic sealing part 7 out of the basket 214. The translation device three 222 drives the push rod 223 to reset, and then the basket 214 continues to descend, and pauses again when the next plastic-sealed component 7 is flush with the push rod 223. Then the translation device three 222 is controlled to push the push rod 223 to translate at the top material position to push the plastic-sealed component 7 out of the basket 214. This cycle is repeated until all the plastic-sealed components 7 in the basket 214 are pushed out. Finally, the basket lifting device lowers the empty basket 214 and places it on the conveyor line one 211 for delivery, and the baskets 214 containing the plastic-sealed components 7 are continuously delivered by the conveyor line two 212.

[0075] In this embodiment, when the translation device three 222 pushes the push rod 223 to translate without contacting the plastic sealing component 7, but accidentally collides with the basket 214, the spring 1 226 is stretched. This design can protect the safety of the pushing mechanism 1, the plastic sealing component 7, and the basket 214, and at the same time does not affect the translation device three 222 pushing the push rod 223 to translate and push the plastic sealing component 7 out of the basket 214. Under normal circumstances, the spring 1 226 will not be stretched or will be slightly stretched. Only when the push rod 223 accidentally collides with the basket 214, the spring 1 226 will be significantly stretched to protect the safety of the pushing mechanism 1, the plastic sealing component 7, and the basket 214.

The rotating module two 43 is used to drive the mounting plate four 44 to rotate around a horizontal axis. The settings of the rotating module three 46 and the rotating module two 43 are both used to adjust the position and orientation of the plastic sealing component 7 in real time as needed to ensure that the plastic sealing component 7 on the positioning fixture 47 can be completely, reliably and accurately debonded by laser.

[0082] In this embodiment, if Fig.10As shown, after the three-axis material picking component places the plastic package 7 on the positioning fixture 47, the translation device 41 drives the plastic package 7 to pass directly under the visual camera 412, the three-dimensional laser line scanner 49, and the ion wind knife 410, and enters the laser 413 for laser debonding. Specifically, the plastic package 7 first comes directly under the ion wind knife 410, and the surface of the plastic package 7 is cleaned by the ion wind knife 410. Then, the plastic package 7 comes directly under the visual camera 412, and the debonding range is visually calibrated by the visual camera 412. Then, the plastic package 7 comes directly under the three-dimensional laser line scanner 49. Below, the degumming thickness is confirmed by the three-dimensional laser line scanner 49, and finally the degumming enters the laser 413. The laser 413 automatically switches to a degumming program that matches the excess glue thickness under the control of a computer according to the degumming range visually calibrated by the visual camera 412 and the degumming thickness confirmed by the three-dimensional laser line scanner 49. By repeatedly striking the laser and adjusting the orientation of the plastic package 7, it is possible to accurately remove excess excess glue of different thicknesses. The degumming has high precision and a wide range of applications. It can be applied to degumming of various different types of plastic package 7 products, and is not affected by the thickness of the excess glue. It is very suitable for degumming operations of plastic package 7 products with uneven excess glue thickness.

[0083] In this embodiment, the visual camera 412 identifies the position and area on the plastic package 7 that needs to be debonded through the machine vision system, thereby realizing visual calibration of the debonding range; the glue thickness of a normal and qualified plastic package 7 is known, so after the three-dimensional laser line scanner 49 transmits the scanning data to the computer, the computer compares and analyzes it with the corresponding parameters of the normal and qualified plastic package 7 to quickly confirm the debonding thickness, and then controls the laser 413 to use different laser intensities according to different debonding thicknesses, and adjusts the appropriate orientation of the plastic package 7, that is, uses a debonding program that matches the excess glue thickness, and finally achieves the purpose of accurately removing excess excess glue of different thicknesses by multiple laser strikes and adjusting the orientation of the plastic package 7.

[0084] In this embodiment, after the degumming of the plastic-sealed component 7 is completed, the translation device 41 drives the plastic-sealed component 7 to come under the ion wind knife 410 again, and the surface of the plastic-sealed component 7 is cleaned by the ion wind knife 410. The cleaned plastic-sealed component 7 comes under the visual camera 412 again for quality inspection to confirm whether the degumming effect meets the standards. If it is unqualified, the degumming operation is performed again until the visual monitoring is qualified. Only after the qualified plastic-sealed component 7 can be taken away by the three-axis material picking component 2.

[0085] In this embodiment, if Fig.11As shown, the unloading product transfer station 5 includes a three-axis material picking component 2, a conveyor 57, a dust removal device and a pusher mechanism 2. The three-axis material picking component 2, the conveyor 57, the dust removal device and the pusher mechanism 2 are all fixedly connected to the machine 1. The three-axis material picking component 2 transfers the qualified plastic-sealed parts 7 on the positioning fixture 47 after laser debonding to the dust removal device, and the dust removal device performs secondary dust removal on the plastic-sealed parts 7 to ensure that the plastic-sealed parts 7 are clean and tidy. The plastic-sealed parts 7 after dust removal are transferred to the conveyor 57 by the three-axis material picking component 2, and the conveyor 57 drives the plastic-sealed parts 7 to move closer to the unloading basket conveying station 6. When the plastic-sealed parts 7 move to the end of the conveyor 57, the pusher mechanism 2 pushes the plastic-sealed parts 7 into the empty basket 214 in the unloading basket conveying station 6. After the basket 214 is full of plastic-sealed parts 7, the unloading basket conveying station 6 sends the basket 214 away.

After the plastic-sealed component 7 is conveyed to the end of the conveyor 57, it is detected by the in-position sensor three 310, and then the lifting device 311 lifts and blocks the plastic-sealed component 7 from continuing to move, waiting for the pushing mechanism two to push the plastic-sealed component 7 into the empty basket 214 in the unloading basket conveying station 6. When the pushing mechanism two arrives at the working position and prepares to push the plastic-sealed component 7, the lifting device 311 is reset.

[0089] In this embodiment, when the translation device 7 59 drives the lever 513 to translate without contacting the plastic sealing component 7 but accidentally collides with the lifting basket 214, the spring 2 516 is stretched. This design can protect the safety of the pushing mechanism 2, the plastic sealing component 7 and the lifting basket 214, and at the same time does not affect the translation device 7 59 driving the lever 513 to translate and push the plastic sealing component 7 into the empty lifting basket 214 in the unloading lifting basket conveying station 6. Under normal circumstances, the spring 2 516 will not be stretched or will be slightly stretched. Only when the lever 513 accidentally collides with the lifting basket 214, the spring 2 516 will be significantly stretched to protect the safety of the pushing mechanism 2, the plastic sealing component 7 and the lifting basket 214.

[0090] In this embodiment, the structure of the unloading basket conveying station 6 is the same as that of the loading basket conveying station 2. In the unloading basket conveying station 6, the empty basket 214 is delivered to the end by the conveyor line 212, and then the basket lifting device clamps the empty basket 214 and drives the empty basket 214 to descend. At the same time, the motor 28 rotates to drive the blocking rod 218 to rotate and leave the opening of the basket 214. Then, when the empty basket 214 descends to a certain installation groove 215 and is flush with the plastic sealing part 7 on the conveyor 57, The empty basket 214 is suspended from descending when the pushing mechanism 2 pushes the plastic-sealed parts 7 into the empty basket 214, and then the empty basket 214 continues to descend until the next mounting slot 215 is flush with the plastic-sealed parts 7 on the conveyor 57, and then the descent is suspended again, and the aforementioned actions are repeated until the empty basket 214 is filled with plastic-sealed parts 7. After the basket 214 is filled with plastic-sealed parts 7, the motor 28 rotates to drive the blocking rod 218 to rotate in the opposite direction and reset to the open position, and then the basket lifting device lowers the basket 214 to the conveyor line 1 211 for delivery.
