Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor processing, and specifically to a packaging and engraving platform that can support dual-model compatible operations. Background Art

[0002] Semiconductors are used in fields such as integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, and high-power power conversion. For example, diodes are devices made of semiconductors; during the semiconductor processing process, operations such as packaging and engraving need to be performed, and the engraving platform is an important part during semiconductor packaging and engraving.

[0003] When performing packaging and engraving, some companies use a 77.5-mm wide substrate engraving solution, but it cannot meet the engraving process requirements of a 74-mm substrate. When processing different product models, the engraving platform needs to be frequently replaced during each processing operation. And during each installation, in order to ensure the processing accuracy, its position needs to be calibrated. This not only increases the work intensity of the staff, but also greatly increases the error rate due to multiple disassembly, installation, and positioning, affecting the processing accuracy, and at the same time resulting in low processing efficiency, which is not conducive to actual use.

[0009] As a further solution of the present invention, the clamping mechanism includes turning shaft rods symmetrically installed up and down on one side inside the cavity of the rotating frame. Two parallel mounting surfaces are symmetrically cut on the side of the turning shaft rod. Clamping plates are fixedly installed on the two parallel mounting surfaces of the two turning shaft rods facing away from each other. The two clamping plates on the two turning shaft rods are symmetrically distributed up and down. Both ends of the turning shaft rod are rotatably connected to the rotating frame through bearings. One end of the two turning shaft rods close to the positioning block penetrates the rotating frame and is fixedly connected to the turning connection block. The two turning connection blocks at the ends of the two turning shaft rods are symmetrically distributed in an inverted V shape up and down. A transmission cylinder is fixedly installed on the side of the two turning connection blocks, and the transmission cylinder is connected to the clamping driving mechanism.

[0010] As a further solution of the present invention, the clamping driving mechanism includes a convex slide seat slidably sleeved on two smooth rods. Adjusting grooves are symmetrically penetrated through the side of the convex slide seat. An adjusting cylinder is fixedly installed on the side of the convex slide seat away from the rotating frame. A return spring is inserted on the side of the convex slide seat close to the positioning block. A guiding round rod is fixedly installed on the side of the positioning block close to the convex slide seat. One end of the return spring abuts against the positioning block, and the return spring is sleeved on the guiding round rod.

[0011] As a further solution of the present invention, circular through holes are symmetrically penetrated through the side of the convex slide seat. The smooth rod penetrates the circular through hole, and the circular through hole is slidably connected to the smooth rod. The transmission cylinder is inserted into the adjusting groove, and the transmission cylinder is slidably connected to the adjusting groove.

[0012] As a further solution of the present invention, the unlocking transmission mechanism includes a bidirectional transmission screw rotatably installed in the groove.

One end of the transmission seat passes through the L-shaped groove and extends to the outside.

[0013] As a further solution of the present invention, a locking mechanism is fixedly installed inside the concave support seat. The locking mechanism is arranged below the rotating shaft. The locking mechanism includes a cylinder fixedly installed on the concave support seat. The upper end of the piston rod of the cylinder is fixedly installed with a locking tooth plate.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. During operation, a new substrate needs to be placed on the upper end of the double-sided platform first. At this time, the unlocking transmission mechanism drives the two clamping drive mechanisms to move away from each other. The clamping drive mechanisms push the two clamping mechanisms to open, so that the clamping plates in the clamping mechanisms move away from the double-sided platform. At this time, if there are processed parts on the double-sided platform, they can be removed from the double-sided platform first, and then a new substrate can be installed. If not, a new substrate can be directly installed. The substrate is inserted downward along the positioning vertical plate on the side of the double-sided platform, so as to complete the accurate installation of the substrate.

[0017] 2. After the installation of the new substrate is completed, the second knob is rotated reversely to drive the bidirectional transmission screw to rotate reversely, so that the two movable plates drive the two transmission seats to move closer to each other. At this time, under the action of the elastic force of the two return springs, the two convex sliding seats are pushed to slide back. The two convex sliding seats both push the transmission cylinder and the flipping connecting block to rotate closer to each other, so that the clamping plates clamp on the upper end of the substrate, thus completing the clamping and fixing of the substrate. At this time, the encapsulation and engraving processing operations can be carried out well.

[0018] 3. When it is necessary to process semiconductors of different models, that is, when the lower side of the double-sided platform needs to be used, first, the piston rod of the cylinder contracts to separate the locking tooth plate from the gear ring. At this time, the output shaft of the stepping motor drives the rotating shaft to rotate a half circle, and the rotating shaft drives the rotating frame to rotate 180 degrees through the fixed seat, so that the rotating frame flips. The rotating frame drives the double-sided platform to flip through the positioning mechanism and the clamping mechanism, so that the lower side of the double-sided platform flips to the upper end. After the adjustment is completed, the locking tooth plate is clamped with the gear ring to lock the gear ring, so that the rotating frame can be kept stable, and then the double-sided platform can be kept stable, ensuring that the subsequent processing can be carried out stably.

[0019] 4. When it is necessary to disassemble the double-sided platform, the unlocking transmission mechanism drives the two clamping driving mechanisms to move away from each other, and the clamping driving mechanisms push the two clamping mechanisms to open, so that the clamping plates in the clamping mechanisms move away from the double-sided platform; at this time, by turning the first knob, the round shaft rotates, and the round shaft drives the threaded column to rotate, so that the strip plate moves away from the double-sided platform, and the strip plate drives the positioning card plate to move out of the card slot on the side of the double-sided platform, thus loosening the locking of the double-sided platform. At this time, the double-sided platform can be conveniently disassembled. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 9 , the present invention provides a technical solution: an encapsulation and engraving platform that supports dual-machine type compatible operation, including a concave support base 1. A rotating frame 2 is rotatably installed inside the concave support base 1. One side of the rotating frame 2 is fixedly connected to a fixed seat 22. The side of the fixed seat 22 away from the rotating frame 2 is fixedly connected to a rotating shaft 23. The rotating shaft 23 is rotationally connected to the concave support base 1 through a bearing. The rotating shaft 23 is driven by the output shaft of a stepping motor fixedly installed on the outer side surface of the concave support base 1. The side of the rotating frame 2 away from the fixed seat 22 is fixedly connected to a rotating shaft. The rotating frame 2 is rotationally connected to the concave support base 1 through the rotating shaft and the rotating shaft 23;

[0032] The concave support base 1 is fixedly installed on a sliding table or a moving device, which can realize the movement adjustment of the concave support base 1, thereby facilitating loading and unloading;

[0033] A double-sided platform 4 is installed inside the rotating frame 2. The double-sided platform 4 has workbenches on both the upper and lower sides of a platform. The workbenches on both sides can perform encapsulation and engraving processing on two different types of semiconductor products as needed. For example, the upper side surface of the double-sided platform 4 can be set to meet the engraving process requirements of a 74mm substrate, and the lower side surface of the double-sided platform 4 can be set to meet the engraving process requirements of a 775.5mm substrate. Clamping mechanisms are symmetrically installed on the left and right sides of the double-sided platform 4;

[0034] A positioning block 24 is symmetrically fixedly connected to one side of the rotating frame 2, and a polished rod 25 is symmetrically fixedly connected between the two positioning blocks 24. The two polished rods 25 are arranged in parallel, and the two positioning blocks 24 and the fixed seat 22 are on the same side of the rotating frame 2. The two polished rods 25 are both inserted into the fixed seat 22, and the clamping drive mechanisms are symmetrically sleeved on the two polished rods 25. One end of the concave support seat 1 is recessed downward to open a groove 11, and an unlocking transmission mechanism is installed in the groove 11.

[0035] See also Figure 8 and Figure 9 Guide grooves 21 are provided on the left and right sides of the rotating frame 2, and a positioning mechanism of a double-sided platform 4 is symmetrically installed on the inner side of the rotating frame 2. The positioning mechanism includes a circular shaft 3 rotatably installed on the side of the rotating frame 2, and the two ends of the circular shaft 3 are respectively fixedly connected with a first knob 31 and a threaded column 32. Notches are symmetrically provided on the left and right sides of the rotating frame 2, and the first knob 31 is installed in the notch to ensure that the first knob 31 will not collide with other components during the rotation of the rotating frame 2. A strip plate 33 is sleeved on the threaded column 32, and the strip plate 33 is threadedly connected to the threaded column 32. A guide plate 34 is fixedly connected to one side of the strip plate 33, and a plurality of positioning clamping plates 35 are equidistantly fixedly connected to the side of the strip plate 33 away from the guide plate 34.

[0036] The guide plate 34 is slidably connected to the guide groove 21 . A plurality of slots 41 are equidistantly formed on the left and right sides of the double-sided platform 4 . The positioning clamping plate 35 is clamped to the slots 41 .

[0037] The first knob 31 is rotated to drive the round shaft 3 to rotate, and the round shaft 3 drives the threaded column 32 to rotate, and the threaded column 32 rotates along the strip plate 33. At this time, the strip plate 33 moves left and right along the threaded column 32. When the strip plate 33 moves, the guide plate 34 is driven to slide left and right along the guide groove 21, so that the strip plate 33 can move stably.

[0038] As the strip plate 33 moves, it drives the positioning card plate 35. When the positioning card plate 35 is inserted into the card slot 41, the double-sided platform 4 is clamped and positioned. When the positioning card plate 35 is removed from the card slot 41, the fixation of the double-sided platform 4 is released, so that the double-sided platform 4 can be easily installed and disassembled.

[0039] The sides of the double-sided platform 4 are all fixedly connected with positioning vertical plates, and the substrate can be guided by the arranged positioning vertical plates, so that the substrate can be conveniently installed on the double-sided platform 4.

[0040] See also Figure 1 , Figure 7 and Figure 9, the clamping mechanism includes turning shafts 5 that are symmetrically installed up and down on one side of the inner cavity of the rotating frame 2. The two turning shafts 5 are arranged on one side of the double-sided platform 4, and the turning shafts 5 do not contact the double-sided platform 4. Two parallel mounting surfaces are symmetrically removed from the upper and lower sides of the side surface of the turning shaft 5. Clamping plates 51 are fixedly installed on the two parallel mounting surfaces that are relatively far away from each other on the two turning shafts 5. The two clamping plates 51 on the two turning shafts 5 are symmetrically distributed up and down. Both ends of the turning shaft 5 are rotationally connected to the rotating frame 2 through bearings. One end of the two turning shafts 5 close to the positioning block 24 penetrates through the rotating frame 2 and is fixedly connected to the flipping connection block 52. The two flipping connection blocks 52 at the ends of the two turning shafts 5 are symmetrically distributed in an inverted V shape up and down. A transmission cylinder 53 is fixedly installed on the side surface of the two flipping connection blocks 52. The transmission cylinder 53 is connected to the clamping driving mechanism.

[0041] On the side where the two clamping plates 51 face each other, a clamping portion protrudes downward. The two clamping plates 51 are symmetrically distributed above and below the double-sided platform 4. After the substrate is installed on the double-sided platform 4, the clamping plates 51 in the two clamping mechanisms cooperate to press the substrate downward, so that the substrate is stably located on the double-sided platform 4. The substrate is clamped through the cooperation of the clamping mechanism and the double-sided platform 4, so that the substrate is stably placed on the double-sided platform 4.

[0042] Please refer to Figures 5 to 9 , the clamping driving mechanism includes a convex slide 6 that is slidably sleeved on two optical rods 25. Adjustment slots 61 are symmetrically penetrated through the upper and lower sides of the side surface of the convex slide 6. An adjustment cylinder 62 is fixedly installed on the side of the convex slide 6 away from the rotating frame 2. A return spring 63 is inserted on the side of the convex slide 6 close to the positioning block 24. A guiding round rod 26 is fixedly installed on the side of the positioning block 24 close to the convex slide 6. One end of the return spring 63 abuts against the positioning block 24, and the return spring 63 is sleeved on the guiding round rod 26.

[0043] The length of the return spring 63 is longer than that of the guiding round rod 26. When the return spring 63 is in a compressed state, the end of the guiding round rod 26 is still inside the return spring 63, and the return spring 63 exerts an elastic force on the convex slide 6;

[0044] Circular through holes are symmetrically penetrated through the upper and lower sides of the side surface of the convex slide 6. The optical rods 25 penetrate through the circular through holes, and the circular through holes are slidably connected to the optical rods 25. The transmission cylinder 53 is inserted into the adjustment slot 61, and the transmission cylinder 53 is slidably connected to the adjustment slot 61.

[0045] By pushing the adjusting cylinder 62, the convex slide 6 is driven to slide along the optical rod 25, so that the convex slide 6 can move stably. When the convex slide 6 moves, the convex slide 6 presses the return spring 63, and at the same time, the transmission cylinder 53 slides along the adjustment groove 61. By the convex slide 6 pushing the transmission cylinder 53 and the flipping connecting block 52 to rotate, the two flipping connecting blocks 52 in a clamping drive mechanism rotate outward and open, making the V-shaped opening of the two flipping connecting blocks 52 larger.

[0046] When the flipping connecting block 52 rotates, it drives the flipping shaft rod 5 to rotate. The rotation directions of the two flipping connecting blocks 52 in a clamping drive mechanism are opposite, so that the rotation directions of the two flipping shaft rods 5 in a clamping mechanism are opposite. The two clamping plates 51 are driven to rotate and open by the two flipping shaft rods 5, so that the clamping plates 51 release the clamping of the substrate. At this time, the substrate can be conveniently taken out from the double-sided platform 4.

[0047] The positioning card plate 35 is arranged between the two flipping shaft rods 5, and the positioning card plate 35 does not affect the normal rotation of the flipping shaft rods 5 and the clamping plates 51.

[0048] Please refer to Figure 1 、 Figure 2 and Figure 7 As shown in FIGS.

[0049] The unlocking transmission mechanism includes a bidirectional transmission screw 8 rotatably installed in the groove 11. Shafts are integrally formed at both ends of the bidirectional transmission screw 8. The bidirectional transmission screw 8 is rotatably connected to the concave support 1 through the shafts. One end of each of the two shafts penetrates through the concave support 1 and is fixedly sleeved with a second knob 81. Movable plates 82 are symmetrically sleeved on the left and right sides of the bidirectional transmission screw 8. The movable plates 82 are threadedly connected to the bidirectional transmission screw 8. The movable plates 82 are arranged in the groove 11. A transmission seat 83 is fixedly connected to the lower end of the side surface of the movable plate 82. L-shaped grooves 12 are symmetrically opened at the bottom of the groove 11. The lower ends of the L-shaped grooves 12 penetrate through the concave support 1 and communicate with the outside. The movable plate 82 and the transmission seat 83 form an L-shaped movable seat, and both the movable plate 82 and the transmission seat 83 are slidably connected to the L-shaped groove 12. One end of the transmission seat 83 passes through the L-shaped groove 12 and extends to the outside.

[0050] A semi-cylindrical groove is formed on one side of the transmission seat 83. The semi-cylindrical groove matches the adjusting cylinder 62. When the transmission seat 83 approaches the adjusting cylinder 62, the semi-cylindrical groove on the side surface of the transmission seat 83 is stuck on the adjusting cylinder 62.

[0051] By rotating the second knob 81 to drive the bidirectional transmission screw 8 to rotate, when the bidirectional transmission screw 8 rotates, it drives the two movable plates 82 thereon to approach or move away from each other, and the movable plate 82 drives the transmission seat 83 to slide left and right along the L-shaped groove 12.

[0052] Please refer to Figure 3 , Figure 4 and Figure 7 , a locking mechanism is fixedly installed inside the concave support base 1. The locking mechanism is arranged below the rotating shaft 23. The locking mechanism includes a cylinder 7 fixedly installed on the concave support base 1. The upper end of the piston rod of the cylinder 7 is fixedly installed with a locking tooth plate 71. The side of the locking tooth plate 71 is slidably connected with a T-shaped guide rail 72. The T-shaped guide rail 72 is fixedly connected to the inside of the concave support base 1. A gear ring 73 is fixedly sleeved on the rotating shaft 23. The locking tooth plate 71 is engaged with the gear ring 73.

[0053] A T-shaped groove is formed on one side of the locking tooth plate 71 close to the inside of the concave support base 1. The T-shaped groove is slidably connected with the T-shaped guide rail 72 up and down.

[0054] The output shaft of the stepping motor rotates a half circle each time. The output shaft of the stepping motor drives the rotating shaft 23 to rotate a half circle. The rotating shaft 23 drives the rotating frame 2 to rotate 180 degrees through the fixed seat 22, so as to turn the rotating frame 2;

[0055] When the rotating frame 2 needs to be turned over, the piston rod of the cylinder 7 needs to contract first, so that the locking tooth plate 71 slides along the T-shaped guide rail 72, so that the locking tooth plate 71 can move stably. After the locking tooth plate 71 moves downward, it is separated from the gear ring 73, so that the locking tooth plate 71 releases the locking of the gear ring 73. At this time, the rotating shaft 23 can rotate;

[0056] When the turning adjustment of the rotating frame 2 is completed, the piston rod of the cylinder 7 drives the locking tooth plate 71 to move upward, so that the locking tooth plate 71 is engaged with the gear ring 73, so as to lock the gear ring 73. Since the gear ring 73 is fixedly connected to the rotating shaft 23, the rotating shaft 23 cannot rotate at this time, and further the fixed seat 22 and the rotating frame 2 cannot rotate, completing the locking of the rotating frame 2, so that the rotating frame 2 can be kept stable.

[0057] Working principle: During operation, a new substrate needs to be placed on the upper end of the double-sided platform 4 first. At this time, turning the second knob 81 drives the bidirectional transmission screw 8 to rotate. The bidirectional transmission screw 8 drives the two movable plates 82 thereon to move away from each other. The two movable plates 82 drive the two transmission seats 83 to slide left and right along the L-shaped groove 12. The two transmission seats 83 push the two adjusting cylinders 62 to move away from each other. The adjusting cylinder 62 drives the convex slide block 6 to slide along the optical rod 25, so that the transmission cylinder 53 slides along the adjusting groove 61. The convex slide block 6 pushes the transmission cylinder 53 and the flipping connecting block 52 to rotate, so that the two flipping connecting blocks 52 in a clamping drive mechanism open outwards and rotate. The flipping connecting block 52 drives the flipping shaft rod 5 to rotate, so that the rotation directions of the two flipping shaft rods 5 in a clamping mechanism are opposite. The two flipping shaft rods 5 drive the two clamping plates 51 to rotate and open;

[0058] At this time, if there are processed parts on the double-sided platform 4, they can be removed from the double-sided platform 4 first, and then a new substrate can be installed. If not, a new substrate can be directly installed. The substrate is inserted downward along the positioning vertical plate on the side of the double-sided platform 4, so as to complete the accurate installation of the substrate;

[0059] After the installation of the new substrate is completed, turn the second knob 81 in the reverse direction. The second knob 81 drives the bidirectional transmission screw 8 to rotate in the reverse direction. The bidirectional transmission screw 8 drives the two movable plates 82 thereon to move closer to each other. The two movable plates 82 drive the two transmission seats 83 to move closer to each other;

[0060] At this time, under the action of the elastic force of the two return springs 63, the two convex slide blocks 6 are pushed to slide back. The two convex slide blocks 6 both push the transmission cylinder 53 and the flipping connecting block 52 to rotate closer to each other. The flipping connecting block 52 drives the flipping shaft rod 5 to rotate. The flipping shaft rod 5 drives the clamping plate 51 to rotate back, so that the clamping plate 51 clamps on the upper end of the substrate, thus completing the clamping and fixing of the substrate. At this time, the encapsulation and engraving processing operations can be carried out well.

[0061] When different models of semiconductors need to be processed, that is, when the lower side of the double-sided platform 4 needs to be used, first, the piston rod of the cylinder 7 contracts, so that the locking tooth plate 71 is separated from the gear ring 73;

[0062] At this time, the output shaft of the stepping motor drives the rotating shaft 23 to rotate by a half circle. The rotating shaft 23 drives the rotating frame 2 to rotate by 180 degrees through the fixed seat 22, so that the rotating frame 2 flips. The rotating frame 2 drives the double-sided platform 4 to flip through the positioning mechanism and the clamping mechanism, so that the lower side of the double-sided platform 4 is flipped to the upper end;

[0063] After the adjustment is completed, the piston rod of the air cylinder 7 drives the locking tooth plate 71 to move upward, so that the locking tooth plate 71 is engaged with the gear ring 73, thereby locking the gear ring 73. At this time, the rotating shaft 23 cannot rotate, and further the fixed seat 22 and the rotating frame 2 cannot rotate, completing the locking of the rotating frame 2, enabling the rotating frame 2 to maintain stability, and further enabling the double-sided platform 4 to maintain stability, ensuring that the subsequent processing can proceed stably.

[0064] When the double-sided platform 4 needs to be disassembled, the unlocking transmission mechanism drives the two clamping drive mechanisms to move away from each other. The clamping drive mechanisms push the two clamping mechanisms to open, so that the clamping plates 51 in the clamping mechanisms move away from the double-sided platform 4;

[0065] At this time, by rotating the first knob 31 to drive the round shaft 3 to rotate, the round shaft 3 drives the threaded column 32 to rotate, so that the strip plate 33 moves away from the double-sided platform 4. The strip plate 33 drives the positioning card plate 35 to move out of the card slot 41 on the side of the double-sided platform 4, thereby releasing the locking of the double-sided platform 4. At this time, the double-sided platform 4 can be conveniently disassembled.

[0066] During installation, first place the double-sided platform 4 between the two positioning mechanisms. By rotating the two first knobs 31, the strip plates 33 in the two positioning mechanisms move closer to the double-sided platform 4. The strip plates 33 drive the positioning card plates 35 to be inserted into the card slot 41, thereby completing the fixation of the double-sided platform 4.
