Description

Technical Field

[0001] This invention relates to the field of semiconductor packaging technology, and more specifically to a chip laser cutting and printing substrate. Background Technology

[0002] In semiconductor packaging processes, laser cutting and die placement are critical steps determining packaging quality and efficiency. Traditionally, the cutting and die placement processes typically use independent carrier equipment. After cutting, the chip must be transferred manually or by a robotic arm and repositioned onto the die placement carrier before subsequent die placement can proceed. This step-by-step approach has several significant drawbacks: First, multiple clamping operations can introduce positional deviations, affecting placement accuracy, especially when processing miniaturized and thin chips, where positioning errors directly impact yield. Second, cut chips are prone to shifting, flipping, or contamination during transfer, increasing operational risks and quality control difficulties. Third, the independent operation of the cutting and die placement carriers prevents rapid connection between workstations, limiting production cycle time and resulting in low overall efficiency. Fourth, existing carriers often use simple vacuum adsorption or mechanical clamping to fix chips, which lacks precise corner positioning for laser cutting, leading to micro-movements or warping during cutting and affecting the quality of the cut surface. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed and easy-to-use chip laser cutting and printing substrate carrier. It achieves precise positioning of the chip during cutting through an adjustable contact rod and a limiting mechanism. Combined with the integrated design of a rotatable substrate carrier and a heating rod, it realizes the integrated operation of rapid chip transfer, preheating and substrate placement after cutting, which significantly improves the efficiency of process connection and substrate placement quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it comprises a fixing plate, a cutting carrier plate, and a patch carrier plate, wherein the cutting carrier plate is fixed to one side of the upper surface of the fixing plate, and the patch carrier plate is connected to the other side of the upper surface of the fixing plate via a shaft; it further comprises: The abutment rods are a plurality of rods arranged in a matrix on the upper surface of the cutting plate, and the abutment rods are connected to the cutting plate through an adjustment mechanism. The limiting mechanism consists of four parts, each located on the top of abutment rods at one of the four corners. An equal-angle rotation mechanism is provided inside the fixed plate and is connected to the shaft at the bottom of the patch carrier plate. The fixing rods are multiple in number and are set at equal angles on the upper side of the patch carrier plate. The top of the fixing rods is connected to the patch module through a connecting mechanism. The heating rods are of several kinds and are equally arranged in a matrix inside the upper end of the fixed rod. The upper end of the heating rod is inserted into the groove on the lower side wall of the patch module. The above technical solution involves selecting a corresponding number of contact rods based on the chip specifications, adjusting the distribution range of the contact rods to match the chip size using an adjustment mechanism, placing the chip on the contact rods, and then using a limiting mechanism to position the four corners of the chip before cutting. The cut chip is then transferred by a mechanical gripper to the mounting module on the mounting carrier. An equal-angle rotation mechanism drives the mounting carrier to rotate intermittently, enabling sequential loading of materials at each station. Simultaneously, a heating rod preheats the chip, providing the necessary process conditions for subsequent mounting operations.

[0005] As a further improvement of the present invention, the adjusting mechanism includes: The telescopic linkage consists of four links, which are respectively suspended on the upper side of the cutting plate. The two ends of the telescopic linkage away from the center of the cutting plate are connected to a connecting plate by bearings. The connecting plate on one side is fixed to one side wall of the cutting plate, and the connecting plate on the other side is slidably set in a groove on the side wall of the cutting plate by a slider. The adjustment screws consist of four screws, each screwed to a slider on a connecting plate via a thread. Both ends of the adjustment screws are screwed into the cutting plate via bearings. Two opposing adjustment screws are connected by a synchronous pulley transmission assembly. One end of one of the two connected adjustment screws is connected to an adjustment motor, which is embedded and fixed inside the cutting plate. Adjusting rods, there are several adjusting rods, and their two ends are respectively fixed on the shaft at the intersection of the telescopic connecting rods on both sides of the symmetry. The abutment rod is movably sleeved on the adjusting rod; The above technical solution involves starting an adjustment motor, which drives a connected adjustment screw to rotate. This adjustment screw rotates synchronously with the oppositely positioned adjustment screw via a synchronous wheel transmission assembly. The adjustment screw drives a slider to move via a thread, which in turn moves a connecting plate. The connecting plate pulls one end of a telescopic connecting rod, causing the telescopic connecting rod to extend and retract. The shaft at the intersection of the telescopic connecting rods moves the adjustment rod, which in turn moves the abutment rods fitted on the adjustment rod until each abutment rod is adjusted to a position that matches the chip size.

[0006] As a further improvement of the present invention, each of the abutment rods is provided with a movable roller at its bottom, and the movable roller is movably disposed on the upper surface of the cutting plate; this can increase the smoothness of the abutment rod when it moves.

[0007] As a further improvement of the present invention, the limiting mechanism includes: The limiting plate consists of two plates, each disposed on the side of the abutment rod away from the center of the cutting plate. A push rod is screwed into the side wall of the limiting plate adjacent to the abutment rod via a shaft. The push link consists of four push links, which are arranged symmetrically in pairs. The two support rods at the inner end of the push link are connected to the outer end of the push rod through the shaft. After the two support rods at the outer end of the push link pass through the limiting plate, they are screwed with hinge blocks through the shaft. The hinge blocks are slidably arranged in the groove on the side wall of the abutment rod. The double-acting lead screw consists of four screws, which are symmetrically connected to the top of the contact rod via bearings. The two ends of the double-acting lead screw are respectively connected to the corresponding hinge blocks via threads. The symmetrical double-acting lead screws are connected to each other via a synchronous pulley transmission assembly. One end of one of the double-acting lead screws is exposed on the outside of the contact rod. A linkage bevel gear pair is provided inside one corner of the abutment rod, and the two bevel gears in the linkage bevel gear pair are respectively sleeved and fixed on the corresponding two bidirectional lead screws. Through the above technical solution, the bidirectional lead screw exposed on the outside of the contact rod is rotated. The bidirectional lead screw drives the corresponding bidirectional lead screw to rotate synchronously through the synchronous wheel transmission assembly. At the same time, it drives the bidirectional lead screw on the other side to rotate through the bevel gear pair. When each bidirectional lead screw rotates, the hinge blocks on both sides are driven to move towards or away from each other along the slide groove through the thread. The hinge blocks drive the end of the push rod to move, and the support rod at the inner end of the push rod drives the push rod to rotate. The push rod then drives the limit plate to move until the limit plate abuts against the four corners of the chip, thus completing the limit.

[0008] As a further improvement of the present invention, the constant angle rotation mechanism includes: A rotating disk is sleeved and fixed on a shaft on the lower side of the patch carrier plate. The rotating disk is provided with staggered actuation grooves and arc-shaped contact grooves at equal angles. The drive disk is mounted in the fixed plate via a shaft. The drive disk is engaged with the arc-shaped contact groove. A drive rod is fixed at the bottom of the drive disk. A protrusion on the drive rod is inserted into the actuating groove. A rotating motor is fixed on the upper surface of the fixed plate and is located between the cutting carrier plate and the patch carrier plate. The output shaft of the rotating motor is inserted into the fixed plate and is connected to the shaft on the drive disk through a synchronous wheel transmission assembly. The above technical solution involves starting a rotating motor, which drives a drive disk to rotate via a synchronous wheel transmission assembly. The drive disk then drives a drive rod to rotate. When the drive rod rotates to one side of the rotating disk, its protrusion inserts into the actuation groove. As it continues to rotate, it drives the rotating disk to rotate at a certain angle. When the protrusion moves out of the actuation groove, the drive disk abuts against the arc-shaped contact groove, locking the position of the rotating disk. This cycle repeats, achieving intermittent, constant-angle rotation of the patch carrier.

[0009] As a further improvement of the present invention, an annular slide rail is fixed on the lower surface of the patch carrier plate, and the annular slide rail is slidably disposed in an annular groove on the fixed plate. The above technical solutions can increase the stability of the patch carrier when it rotates.

[0010] As a further improvement of the present invention, the connecting mechanism includes: The connecting plate consists of two plates, which are disposed on both sides of the fixing rod. Each connecting plate has an insert plate fixed on the upper side of the side wall adjacent to the fixing rod, and the insert plate is inserted into the slot on the side wall of the patch module. The toothed plates are of several kinds and are equally spaced from top to bottom inside the fixing rod. The toothed plates are fixed to the side walls of the connecting plates on both sides in an alternating manner. The rotating gears are of several kinds and are meshed one-to-one between two symmetrical toothed plates. The rotating gears are screwed to the fixed rod through bearings. The linkage rod is screwed into the fixed rod via a bearing. The linkage rod is connected to the shaft on one of the rotating gears via a bevel gear pair. The other end of the linkage rod is connected to a rotating shaft via a worm gear pair. The rotating shaft is screwed onto the fixed rod via a bearing, and one end of the rotating shaft is exposed on the outside of the fixed rod. With the above technical solution, when it is necessary to replace the surface mount module, rotate the rotating shaft exposed on the outside of the fixed rod. The rotating shaft drives the linkage rod to rotate through the worm gear pair. The linkage rod drives the rotating gear connected to it to rotate through the bevel gear pair. The rotating gear drives the toothed plates on the upper and lower sides to move in opposite directions. At the same time, through the linkage of the other rotating gears, all toothed plates move synchronously. The toothed plates drive the connecting plates and insert plates on both sides to retract inward, so that the insert plates are removed from the slots on the side wall of the surface mount module, and the surface mount module can be removed for replacement.

[0011] As a further improvement of the present invention, a limiting block is embedded in the strip-shaped limiting groove on both sides of the toothed plate, and the limiting block is fixed on the inner wall of the fixing rod. The above technical solution can prevent the toothed plate from moving out of the fixed rod, thus increasing the stability of the toothed plate.

[0012] As a further improvement of the present invention, a limiting ring is sleeved and fixed on the middle end of the heating rod, and a pushing spring is fixed at the lower end of the limiting ring. The pushing spring is sleeved on the lower end of the heating rod and the lower end of the pushing spring is fixed inside the fixing rod. With the above technical solution, when heating the patch module, the heating rod can be pushed by the spring so that the heating rod remains in contact with the patch module.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Adjust the motor drive screw to drive the telescopic connecting rod to deform, and adjust the distribution range of the matrix-type abutment rod synchronously through the adjusting rod, so that the positioning point can quickly adapt to chips of different sizes, achieving precise support and versatility; 2. The bidirectional lead screw drives the hinge block to move inward and clamp the chip at the four corners through the bevel gear pair and synchronous wheel, thereby achieving rapid centering and clamping and ensuring the chip is in a stable position during cutting. 3. The rotating motor drives the cam to intermittently move the rotating disk through the drive disk, and the arc-shaped contact groove locks the station, so that the chip carrier can rotate intermittently at the same angle, which facilitates the sequential feeding of multiple stations and improves the efficiency of chip mounting operation. 4. The rotating shaft drives the insert plate on the connecting plate to extend and retract synchronously through the linkage rod and gear plate mechanism, realizing the quick assembly and disassembly of the patch module; the heating rod is pushed by the spring to always keep in contact with the module, ensuring stable preheating.

Example

[0020] See Figure 2 , Figure 6 As shown, based on Embodiment 1, the equal-angle rotation mechanism 7 includes: Rotating disk 7-1, the rotating disk 7-1 is sleeved and fixed on the shaft on the lower side of the patch carrier plate 3, and the rotating disk 7-1 is provided with actuating grooves 7-1-1 and arc-shaped contact grooves 7-1-2 at equal angles. The drive disk 7-2 is mounted in the fixed plate 1 via a shaft. The drive disk 7-2 is engaged with the arc-shaped contact groove 7-1-2. A drive rod 7-3 is welded and fixed to the bottom of the drive disk 7-2. The protrusion on the drive rod 7-3 is engaged with the actuation groove 7-1-1. The rotating motor 7-4 is fixed on the upper surface of the fixed plate 1 and is located between the cutting carrier plate 2 and the patch carrier plate 3. The output shaft of the rotating motor 7-4 is inserted into the fixed plate 1 and is connected to the shaft on the drive disk 7-2 through the synchronous wheel transmission assembly. Example

[0021] See Figure 1-2 , Figure 7 As shown, based on Embodiment 1, the connecting mechanism 9 includes: There are two connecting plates 9-1, which are located on both sides of the fixing rod 8. Each connecting plate 9-1 is welded and fixed with an insert plate 9-2 on the upper side of the side wall adjacent to the fixing rod 8. The insert plate 9-2 is inserted into the slot on the side wall of the patch module 10. The toothed plates 9-3 are multiple in number and are equidistantly arranged from top to bottom within the fixing rod 8. The toothed plates 9-3 are staggered and fixed to the side walls of the connecting plates 9-1 on both sides. The strip-shaped limiting grooves on both sides of the toothed plates 9-3 are each embedded with a limiting block 14, which is fixed to the inner wall of the fixing rod 8. Rotating gear 9-4, there are several rotating gears 9-4, and they are meshed one-to-one between two symmetrical toothed plates 9-3. The rotating gear 9-4 is screwed to the fixed rod 8 through a bearing. Linkage rod 9-5 is screwed into fixed rod 8 via bearing. Linkage rod 9-5 is connected to the shaft on one of the rotating gears 9-4 via bevel gear pair. The other end of linkage rod 9-5 is connected to rotating shaft 9-6 via worm gear pair. Rotating shaft 9-6 is screwed onto fixed rod 8 via bearing, and one end of rotating shaft 9-6 is exposed on the outside of fixed rod 8.

[0022] When using this invention, according to the chip specifications, the adjusting motor 5-4 is started. The adjusting motor 5-4 drives the adjusting screw 5-3 to rotate. Through the synchronous wheel transmission assembly, the relatively set adjusting screws 5-3 rotate synchronously, driving the slider to move the connecting plate 5-2, which in turn drives the telescopic connecting rod 5-1 to extend and retract. The shaft at the intersection of the telescopic connecting rod 5-1 drives each abutment rod 4 to move through the adjusting rod 5-5, so that the distribution range of the abutment rod 4 array matches the chip size. The moving rollers 12 at the bottom of the abutment rod 4 ensure smooth movement. After completion, the chip is placed on the contact rod 4 and positioned by the four corner limiting mechanisms 6. The bidirectional lead screw 6-5 exposed on the outside of the contact rod 4 is rotated. The bidirectional lead screw 6-5 drives the other bidirectional lead screws 6-5 to rotate synchronously through the synchronous wheel transmission assembly and bevel gear pair, driving the hinge block 6-4 to move along the slide groove on the side wall of the contact rod 4. The hinge block 6-4 drives the push rod 6-2 to rotate through the push connecting rod 6-3. The push rod 6-2 drives the limiting plate 6-1 to move to the four corners of the chip to complete the limiting. At this time, the chip can be cut. After cutting, the cut chips are transferred one by one to the mounting modules 10 on the mounting carrier 3 by a mechanical gripper. The rotating motor 7-4 is started, and the rotating motor 7-4 drives the drive disk 7-2 to rotate through the synchronous wheel transmission assembly. The drive rod 7-3 at the bottom of the drive disk 7-2 rotates accordingly. When the drive rod 7-3 rotates to one side of the rotating disk 7-1, the protrusion on the drive rod 7-3 inserts into the actuation groove 7-1-1 on the rotating disk 7-1, causing the rotating disk 7-1 to rotate at a certain angle. When the protrusion moves out of the actuation groove 7-1-1, the drive disk 7-2 abuts against the arc-shaped contact groove 7-1-2 on the rotating disk 7-1, achieving intermittent positioning. The annular slide rail 13 at the bottom of the mounting carrier 3 cooperates with the annular slide groove on the fixed plate 1 to ensure the stability of the rotation process. Through the intermittent drive of the equal angle rotation mechanism 7, the mounting carrier 3 sequentially delivers each mounting module 10 to the working position. While the chip is placed on the surface mount module 10, the heating rod 11 inside the fixing rod 8 is activated. Under the action of the pushing spring 16, the heating rod 11 always keeps in close contact with the groove at the bottom of the surface mount module 10 to preheat the chip and provide temperature conditions for subsequent surface mount operations. When it is necessary to replace the surface mount module 10 of different specifications, the rotating shaft 9-6 exposed on the outside of the fixing rod 8 is rotated. The rotating shaft 9-6 drives the linkage rod 9-5 to rotate through the worm gear pair. The linkage rod 9-5 drives the rotating gear 9-4 to rotate through the bevel gear pair. The rotating gear 9-4 drives the upper and lower interlocking toothed plates 9-3 to move. The toothed plates 9-3 drive the insertion plate 9-2 to exit from the slot on the side wall of the surface mount module 10 through the connecting plate 9-1, so that the surface mount module 10 can be easily replaced. The limiting blocks 14 on both sides of the toothed plates 9-3 cooperate with the limiting groove to prevent the toothed plates 9-3 from moving excessively. Through its integrated structural design, this equipment enables continuous operation, allowing chips to be directly transferred to the placement process after dicing, reducing intermediate transfer links and improving production efficiency. Meanwhile, the adjustable array of contact rods 4 and the limiting mechanism 6 adapt to various chip sizes, the equal-angle rotation mechanism 7 ensures the accuracy of the placement position, and the modular placement module 10 allows for easy process switching by changing its structure.

[0023] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. Adjust the motor 5-4 to drive the lead screw to deform the telescopic connecting rod 5-1. Adjust the distribution range of the matrix-type abutment rod 4 synchronously through the adjusting rod 5-5, so that the positioning point can quickly adapt to chips of different sizes, achieving precise support and high versatility. 2. Rotating the bidirectional lead screw 6-5 drives the hinge block 6-4 to drive the linkage mechanism through the bevel gear pair and synchronous wheel transmission, so that the limiting plate 6-1 synchronously presses against the four corners of the chip, realizing rapid centering and clamping, and ensuring that the chip position is firm and stable during cutting; 3. The rotating motor 7-4 drives the convex rod to intermittently move the rotating disk 7-1 through the drive disk 7-2, and locks the station position with the arc-shaped contact groove 7-1-2, so that the chip carrier 3 can achieve intermittent rotation at equal angles, which facilitates the sequential feeding of materials at multiple stations and significantly improves the efficiency of chip mounting operations. 4. The rotating shaft 9-6 drives the insert plate 9-2 on the connecting plate 9-1 to extend and retract synchronously through the linkage rod 9-5 and the gear plate mechanism, so as to realize the quick installation and removal of the patch module 10; the heating rod 11 is pushed by the push spring 16 to always fit the module, ensuring continuous and stable preheating.
