Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor electronic product production, and particularly relates to a loading mechanism and a loading method for a full-automatic integrated circuit plastic encapsulation machine. Background Art

[0002] When loading a full-automatic integrated circuit plastic encapsulation machine, first manually load the frame wafers into a cassette, and then place the cassette at a designated position. The plastic encapsulation machine automatically moves the cassette to the designated position and then transfers the frame wafers to the plastic encapsulation station. The plastic encapsulation machine in the prior art uses a conveyor belt and a pressing air cylinder in cooperation to transfer the frame wafers to the loading port. This method has the following problems: Chips are installed on the frame wafers, and the operation of the pressing air cylinder is likely to squeeze the chips, causing chip damage.

[0003] The Chinese utility model patent with the publication number CN201142321 discloses an "automatic loading machine for integrated circuit plastic encapsulation", which drives a manipulator gripper to grab and load the frame wafers through transmission components. However, in the actual production process, the following technical problems exist:

[0004] First, the size of the loading port of the full-automatic integrated circuit plastic encapsulation machine is small. When using a manipulator gripper to transfer the frame wafers into the loading port, the frame wafers are likely to fall or the frame wafers are likely to collide with the edge of the loading port and deform.

[0005] Second, the manipulator gripper generates pressure on the frame wafers when grabbing the frame wafers, and it is extremely easy to have a situation of pressure overload, resulting in deformation of the frame wafers.

[0006] Therefore, how to stably and accurately transfer the frame wafers into the loading port and timely avoid deformation of the frame wafers is the problem to be solved. Summary of the Invention

[0007] The present invention aims to solve at least one of the above-mentioned technical problems, and provides a loading mechanism and a loading method for a full-automatic integrated circuit plastic encapsulation machine, which can effectively avoid the chips on the frame wafers from being squeezed and damaged and can timely avoid deformation of the frame wafers.

[0008] To achieve the above object, the technical solution adopted by the present invention is:

[0009] The feeding mechanism for a full-automatic integrated circuit plastic packaging machine, which is used to convey frame wafers towards the feeding port of the full-automatic integrated circuit plastic packaging machine, includes a material box, a feeding and discharging conveyor line, and a wafer pushing assembly.

[0018] A feeding method for an integrated circuit fully automatic plastic packaging machine comprises the following steps:

[0019] Providing device: Providing the above-mentioned feeding mechanism for the fully automatic plastic packaging machine for integrated circuits

[0020] The material box is lowered: the lifting drive unit drives the receiving rod to move toward the box carrier plate in a single lowering manner by a preset lowering distance;

[0021] Loading: When the cartridge descends a preset distance, the frame sheet at the bottom of the cartridge corresponds to the pushing bar, and the pushing piece driving part drives the mounting block to move towards the loading port, then the pushing bar pushes the frame sheet into the loading port; as the cartridge gradually moves towards the carrier plate, the pushing bar sequentially pushes the frame sheets in the cartridge into the loading port; when all the frame sheets are pushed out, the cartridge continues to move towards the carrier plate direction;

[0022] When the pushing bar is stuck by the frame sheet, the thrust is greater than the pushing elastic force, then the pushing bar drives the trigger piece to move out of the sensing groove through the driving part and triggers the overload inductor, while giving a warning and stopping the loading operation;

[0023] Cartridge recycling: When the receiving rod moves into the avoiding port, the cartridge is received on the carrier plate; the cartridge pushing driving part drives the cartridge pushing bar to drive the cartridge pushing strip to move along the length of the avoiding port towards the full sensor, then the cartridge is recycled on the carrier plate.

[0024] Due to the above technical solutions, the present invention has the following beneficial effects:

[0025] First, when the pushing bar extends into the card slot, the frame sheet can be sent into the loading port. It can be seen that the present invention uses the pushing bar to push the frame sheet for loading. The pushing bar does not contact the chip, and can effectively avoid the chip on the frame sheet from being squeezed and damaged.

[0026] Second, when the thrust received by the pushing bar is greater than the pushing elastic force, the pushing bar moves in the direction away from the loading port and compresses the pressing spring through the pressing piece. During the compression of the pressing spring, the trigger piece is driven to move out of the sensing groove and trigger the overload inductor, so that the whole device stops the loading operation, that is, the pushing bar no longer moves towards the loading port direction, then the frame sheet is no longer squeezed by the pushing bar. It can be seen that the present invention can timely avoid the deformation of the frame sheet. Description of the Drawings

Specifically, one end of the mounting block 22 is connected to the other end of the vertical rod 274, and the other end of the mounting block 22 extends towards the driving part installation frame 511; when the working rod of the pushing cylinder 272 drives the block to reciprocate along the width direction of the installation frame 31, the mounting block 22 can reciprocate towards or away from the feeding port driven by the vertical rod 274. The brand of the overload inductor 23 is Omron, and the model is EE-SX672. The overload inductor 23 is installed at the bottom of the other end of the mounting block 22, and an induction groove 231 is provided on the overload inductor 23.

[0049] The triggering part includes a driving part 24 and a triggering piece 26. The driving part 24 is located on the side of the mounting block 22 away from the feeding port. The triggering piece 26 is connected to the driving part 24 and the triggering piece 26 extends into the induction groove 231. The pushing strip 21 is slidably installed on the mounting block 22. Specifically, a sliding groove 220 is opened at one end of the mounting block 22 away from the vertical rod 274. The sliding groove 220 penetrates the mounting block 22 along the width direction of the installation frame 31. The pushing strip 21 is slidably arranged through the sliding groove 220; the sliding groove 220 also penetrates the top surface of the mounting block 22 and extends to the bottom of the mounting block 22, forming guide grooves 221 on the top surface and the bottom of the mounting block 22. A bearing 222 is rotatably arranged in each guide groove 221, and the side surface of the bearing 222 contacts the pushing strip 21; when the pushing strip 21 is forced to slide along the sliding groove 220, the bearing 222 can guide the sliding of the pushing strip 21.

[0050] The pushing strip 21 extends towards the feeding port, and one end of the pushing strip 21 away from the feeding port is fixedly connected to the driving part 24. When the pushing strip 21 receives a thrust in the direction away from the feeding port and the thrust is too large, the pushing strip 21 drives the triggering piece 26 to move out of the induction groove 231 through the driving part 24 and triggers the overload inductor 23. Specifically:

[0051] The driving part 24 includes an overload bolt 241, a pressure piece 242, a pressure spring 243 and a connecting plate 244. One end of the overload bolt 241 is fixedly mounted on the mounting block 22, and the other end of the overload bolt 241 extends in a direction away from the loading port. The pressure piece 242 is sleeved on the overload bolt 241. The pressure spring 243 is sleeved on the overload bolt 241. One end of the pressure spring 243 is connected to the end of the overload bolt 241 away from the mounting block 22, and the other end of the pressure spring 243 presses the pressure piece 242 to contact the mounting block 22, so as to give a pushing elastic force to the pressure piece 242. When the thrust applied to the push-out strip 21 is greater than the pushing elastic force, the push-out strip 21 moves in a direction away from the loading port and compresses the pressure spring 243 through the pressure piece 242. During the compression of the pressure spring 243, the trigger piece 26 is driven to move out of the sensing slot 231 and trigger the overload sensor 23.

[0052] In this embodiment, the lifting assembly 5 further includes a front and rear positioning portion 53, which includes a frame plate 531, a vertical plate 532 and a limit plate 533. One side of the frame plate 531 is connected to the side of the drive unit mounting frame 511 away from the loading port, and the frame plate 531 extends in a direction away from the loading port. One end of the vertical plate 532 is placed on the top surface of the frame plate 531 away from the box carrier plate 41, and the other end of the vertical plate 532 extends in a direction toward the box carrier plate 41, and the vertical plate 532 is detachably connected to the frame plate 531. Specifically, the vertical plate 532 is provided with a fixing groove 535, and the fixing groove 535 penetrates the frame plate 531. The frame plate 531 is provided with bolt holes at intervals in a direction away from the loading port, and the vertical plate 532 is detachably connected to the frame plate 531 by bolts 536; one end of the vertical plate 532 is provided with a mounting shaft 534. The limiting plate 533 is located on the side of the frame plate 531 facing the installation frame 31. The side of the limiting plate 533 facing the loading port includes a plane 5331 and an inclined surface 5332. One side of the plane 5331 contacts the frame plate 531. The plane 5331 is parallel to the length direction of the pushing groove 311. One side of the inclined surface 5332 connects the side of the plane 5331 away from the frame plate 531. The horizontal distance from the inclined surface 5332 to the loading port gradually decreases in the direction away from the pushing assembly 3. One end of the limiting plate 533 is sleeved on the installation shaft 534. In the process of the material box 1 moving from the installation frame 31 to the receiving rod 52, under the push of the pushing plate 33, the end of the material box 1 away from the loading port contacts the inclined surface 5332, and under the guidance of the inclined surface 5332, the material box 1 moves until the end of the material box 1 away from the loading port contacts the plane 5331, so that the end of the material box 1 away from the loading port reaches a preset feeding position. Since the frame plate 531 is provided with threaded holes, when the bolts 536 are detached, the vertical connecting plate 532 can be moved to a preset position and then connected to the frame plate 531 , so that the limiting plate 533 can be used to position material boxes 1 of different widths.

[0053] In this embodiment, the lifting assembly 5 further includes a rising limit portion 6, and the rising limit portion includes a mounting strip 61, a height-adjusting shaft 62, and a limit strip 63. The mounting strip 61 is installed at one end of the driving portion mounting frame 511 facing away from the cartridge pushing assembly 4, and one end of the mounting strip 61 extends towards the pushing assembly 3. The height-adjusting shaft 62 is inserted through one end of the mounting strip 61 facing the pushing assembly 3 and can move or be fixed relative to the mounting strip 61. Specifically, a limit threaded hole is provided at one end of the mounting strip 61 facing the pushing assembly 3. When a bolt is screwed into the limit threaded hole and abuts against the height-adjusting shaft 62, the height-adjusting shaft 62 is fixed relative to the mounting strip 61; when the bolt does not abut against the height-adjusting shaft 62, the height-adjusting shaft 62 can move relative to the mounting strip 61. One end of the limit strip 63 is connected to one end of the height-adjusting shaft 62 facing the cartridge pushing assembly 4 and extends towards the pushing assembly 3. A top inclined surface is provided at one end of the bottom surface of the limit strip 63 facing the pushing assembly 3, and the distance from the top inclined surface to the cartridge pushing assembly 4 gradually decreases in the direction away from the pushing assembly 3. During the process of the cartridge 1 moving from the mounting frame 31 to the receiving rod 52, under the pushing of the pushing plate 33, the top surface of the cartridge 1 contacts the top inclined surface, and under the guiding action of the top inclined surface, the cartridge 1 moves until the top surface of the cartridge 1 contacts the bottom surface of the limit strip 63, so that the top surface of the cartridge 1 reaches a preset starting height position. Since the height-adjusting shaft 62 can move or be fixed relative to the mounting strip 61, the distance from the bottom surface of the limit strip 63 to the cartridge carrier plate 41 can be adjusted, so that the limit strip 63 can be used to position cartridges 1 of different heights.

[0054] In this embodiment, the receiving rod 52 includes a strip-shaped shell 521 and an extension strip 523. One end of the strip-shaped shell 521 is connected to the lifting block 513. An adjustment groove 522 is provided on the strip-shaped shell 521. The adjustment groove 522 penetrates through one end of the strip-shaped shell 521 facing away from the lifting block 513, the top surface of the strip-shaped shell 521, and the opposite sides of the strip-shaped shell 521. The extension strip 523 is slidably disposed in the adjustment groove 522, and the opposite sides of the extension strip 523 are limited to the opposite sides of the strip-shaped shell 521 by pins 524. The top surface of the extension strip 523 is flush with the top surface of the strip-shaped shell 521. When the extension strip 523 slides out of the adjustment groove 522, the overall length of the receiving rod 52 can be extended, so that the receiving rod 52 can support a cartridge 1 with a larger width.

[0055] In this embodiment, the pushing assembly 3 further includes an extension plate 34. The extension plate 34 is disposed at one end of the mounting frame 31 facing the lifting driving portion 51 and can slide along the length direction of the mounting frame 31. The width of the extension plate 34 is smaller than the distance between the two receiving rods 52. Specifically, see Figure 4, the propulsion assembly 3 further includes an extension rail 341, an extension cylinder 342, and an extension push bar 343. The number of extension rails 341 is two. The two extension rails 341 are provided at one end of the mounting frame 31 facing the driving part mounting frame 511 and are spaced apart along the width direction of the mounting frame 31. Both of the two extension rails 341 are located between the two moving conveyor belts 327 and extend along the length direction of the mounting frame 31. The extension cylinder 342 is a rotary clamping cylinder of AirTAC brand. The extension cylinder 342 is provided between the two extension rails 341. The operating rod of the extension cylinder 342 extends towards the driving part mounting frame 511. The extension push bar 343 is connected to the operating rod of the extension cylinder 342. Guide blocks are provided on opposite sides of the extension plate 34. The guide blocks are slidably sleeved on the corresponding extension rail 341 on one side. One end of the extension plate 34 is fixedly connected to the extension push bar 343. When the cartridge 1 is too small, the extension cylinder 342 is activated. The operating rod of the extension cylinder 342 pushes the extension plate 34 towards the driving part mounting frame 511 through the extension push bar 343, and the extension plate 34 can support the cartridge 1.

[0056] In this embodiment, on the side of the driving part mounting frame 511 facing the propulsion assembly 3 at the end away from the cartridge plate 41, a feeding inductor 71 is provided. The brand of the feeding inductor 71 is Omron, and the model is EE-SPY401. The feeding inductor 71 is used to collect displacement data of the cartridge 1 along the top surface of the mounting frame 31. On the side of the driving part mounting frame 511 where the frame plate 531 is installed, an initial inductor 72 and a lifting inductor 73 are installed. The brand of the initial inductor 72 is Omron, and the model is EE-SX670. The initial inductor 72 corresponds to the position of the frame plate 531. Specifically, an induction through slot is provided through the side of the frame plate 531 facing the loading port, and the initial inductor 72 corresponds to the induction through slot so that the initial inductor 72 can sense the cartridge 1; the initial inductor 72 is used to collect position data of the cartridge 1 at the top of the lead screw of the lifting motor 512. The brand of the lifting inductor 73 is Omron, and the model is EE-SX670. The lifting inductor 73 is installed at one end of the driving part mounting frame 511 connecting to the table surface 200. The lifting inductor 73 is used to collect the distance data between the bottom surface of the cartridge 1 and the cartridge plate 41. A number of times inductor is provided on the pusher driving part 27. The brand of the number of times inductor is Omron, and the model is ZX-SAM14. Specifically, the number of times inductor is installed on the block; the number of times inductor is used to record the number of operations of the pusher driving part 27.

[0057] In this embodiment, referring to Figure 9 , a feeding mechanism for an integrated circuit full-automatic plastic sealing machine further includes a control system, including a feeding positioning module, an initial positioning module, a distance judgment module, a full module, an overload module, a counting module, a host computer, an alarm, a reminder, and a control module.

[0058] The feeding positioning module is connected to the feeding inductor 71, and the feeding positioning module is used to determine whether the cartridge 1 is located on the receiving rod 52.

[0059] The initial positioning module is connected to the initial inductor 72, and the initial positioning module is used to determine whether the cartridge 1 is located at the preset feeding position.

[0060] The distance judgment module is connected to the lifting inductor 73. The preset descending distance of the cartridge 1 in a single descent in the lifting space is entered in the distance judgment module, and the distance judgment module is used to judge the descending displacement of the cartridge 1.

[0061] The full module is connected to the full inductor 44, and the full module is used to determine whether the cartridge plates 41 are fully filled with the cartridges 1.

[0062] The overload module is connected to the overload inductor 23, and the overload module is used to determine whether the trigger piece 26 is located in the induction groove 231.

[0063] The counting module is connected to the number of times inductor, and the counting module is used to record the number of operations of the pusher driving part 27.

[0064] The feeding positioning module, the initial positioning module, the distance judgment module, the full module, the overload module, and the counting module are all connected to the host computer, and the host computer is connected to the control module.

[0065] The control module is respectively connected to the pusher cylinder 272 of the pusher driving part 27, the propulsion motor 322 of the propulsion driving part 32, the cartridge pushing driving part 42, the lifting motor 512 of the lifting driving part 51, the extension cylinder 342, the alarm and the reminder.

[0066] After receiving the analysis data of different modules, the host computer generates a control instruction, and the control module is used to receive the control instruction from the host computer and control the corresponding components to complete the operation.

[0067] This embodiment also provides a feeding method for an integrated circuit full-automatic plastic sealing machine, including the following steps:

[0068] The cartridge 1 is in place: A number of frame pieces 100 are placed in the cartridge 1, and the number of frame pieces 100 are arranged at intervals according to the preset descending distance; the cartridge 1 is placed in the feeding slot of the mounting frame 31 and the first cartridge 1 is in contact with the pusher plate 33.

[0069] Push the cartridge 1: The control module controls the propulsion motor 322 to drive the pusher plate 33 to move along the length direction of the propulsion slot 311 through the propulsion rod 321, and the cartridge 1 moves towards the driving part mounting frame 511. When the propulsion rod 321 moves to the end of the propulsion slot 311, the cartridge 1 is located on the receiving rod 52.

[0070] The material box 1 descends: The material box 1 blocks the feeding inductor and the initial inductor and generates in-position signals respectively. The feeding inductor feeds the in-position signal back to the feeding positioning module, and the feeding positioning module determines that the material box 1 is already on the receiving rod 52; the initial inductor feeds the in-position signal back to the initial positioning module, and the initial positioning module determines that the material box 1 is already at the preset feeding position. Both the feeding positioning module and the initial positioning module send the judgment results to the host computer. After the host computer generates a control command, the control module controls the lifting motor 512 to drive the receiving rod 52 to move towards the carrier plate 41 in a manner of descending a preset descending distance each time.

[0071] Feeding: When the material box 1 descends a preset descending distance, the frame material sheet 100 at the bottom of the material box 1 corresponds to the pushing strip 21. The pushing sheet cylinder 272 drives the mounting block 22 to move towards the feeding port, and then the pushing strip 21 pushes the frame material sheet 100 into the feeding port; as the material box 1 gradually moves towards the carrier plate 41, the pushing strip 21 successively pushes the frame material sheets 100 in the material box 1 into the feeding port. When all the frame material sheets 100 are pushed out, the material box 1 continues to move towards the carrier plate 41. Specifically, when the number of times inductor feeds the operation times of the pushing sheet driving part 27 back to the counting module, and the counting module determines that the operation times of the pushing sheet driving part 27 are the same as the total quantity, the material box 1 no longer descends at the preset descending distance, but moves towards the carrier plate 41 at a constant speed.

[0072] When the pushing strip 21 is stuck by the frame material sheet 100, the thrust is greater than the pushing elastic force, then the pushing strip 21 drives the trigger piece 26 to move out of the induction groove 231 through the driving part 24 and triggers the overload inductor 23, and at the same time issues a warning and stops the feeding operation; specifically, when the trigger piece 26 moves out of the induction groove 231, the overload inductor 23 senses that the trigger piece 26 is no longer in the induction groove 231 and generates a no-piece signal, and feeds the no-piece signal back to the overload module. The overload module determines that the trigger piece 26 is not in the induction groove 231, and the overload module sends the judgment result to the host computer. After the host computer generates a control command, the control module controls the alarm to sound an alarm and controls the pushing sheet cylinder to stop operating. The operator goes to deal with it after receiving the alarm signal.

[0073] Recycling of the material box 1: When the receiving rod 52 moves into the avoidance port 411, the material box 1 is received on the placement plate of the carrier plate 41. When the lifting inductor 73 senses that the lifting distance between the material box 1 and the carrier plate 41 is zero, the control module controls the pushing box driving part 42 to drive the pushing box bar 421 to drive the pushing box strip 43 to move along the length of the avoidance port 411 towards the full sensor 44, and then the material box 1 is recycled on the carrier plate 41. When the full sensor 44 is blocked by the material box 1, it can be judged that the carrier plate 41 is already full of material boxes 1. At this time, the control module controls the reminder to give a reminder, and then the operator takes out the empty material box 1.

[0074] When feeding the frame sheet 100 using the above feeding mechanism and method, the beneficial effects are as follows:

[0075] First, when the pushing bar 21 extends into the card slot 11, the frame sheet 100 can be fed into the feeding port. It can be seen that the present invention uses the pushing bar 21 to push the frame sheet 100 for feeding. The pushing bar 21 does not contact the chip, effectively avoiding extrusion damage to the chip on the frame sheet 100.

[0076] Second, when the thrust received by the pushing bar 21 is greater than the pushing elastic force, the pushing bar 21 moves in the direction away from the feeding port and compresses the pressing spring 243 through the pressing piece 242. During the compression of the pressing spring 243, the trigger piece 26 is driven to move out of the induction groove 231 and trigger the overload inductor 23, causing the entire device to stop the feeding operation, that is, the pushing bar 21 no longer moves in the direction of the feeding port, so the frame sheet 100 is no longer extruded by the pushing bar 21. It can be seen that the present invention can timely avoid deformation of the frame sheet 100.

[0077] The above description is a detailed description of the preferred feasible embodiment of the present invention, but the embodiment is not intended to limit the scope of the patent application of the present invention. Any equivalent changes or modifications made under the technical spirit disclosed by the present invention should fall within the scope of the patent covered by the present invention.
