[0002] Semiconductor plastic packaging press is a kind of equipment specially used in the packaging process of semiconductor devices. It is mainly used to combine semiconductor chips and packaging materials together to protect the electronic components inside the package.
[0003] During its use, in order to prevent dust and debris in the air from being adsorbed onto the upper or lower mold of the press body, the prior art mostly uses an air gun to manually blow the mold surface after each molding operation to remove dust and impurities on the upper or lower mold.

In addition, manual blowing actions need to be repeated during operation, which is labor-intensive.

The dust suction assembly 50 is connected with the roller brush head assembly 40 through the dust extraction pipe assembly 60, and the trigger mechanism and the electric control part are arranged on the carrier 10, and when the trigger mechanism is triggered, the electric control part controls the movement of the moving assembly 30, and the moving assembly 30 drives the roller brush head assembly 40 to reciprocate along the length direction of the carrier 10.
[0059] The working principle and beneficial effects of the above technical solution are:
[0060] First, the carrier platform 10 is detachably mounted on the square tube of the upper beam of the semiconductor molding press by means of the clamping assembly 20. The specific operation is to adjust the position of the carrier platform 10 and the column 21 thereon so that the column 21 is located directly below the square tube at the upper beam of the molding press. Then, the carrier platform 10 is moved upward so that the upper surfaces of the two columns 21 contact and squeeze the lower surface of the square tube at the corresponding position. The triggering part 23 on the column 21 is squeezed by the reaction force of the square tube, thereby driving the two clamping blocks 22 to clamp onto the square tube, connecting and fixing the carrier platform 10 relative to the square tube, and completing the installation process of the device.
[0061] Then, after each mold brushing is completed, the safety light curtain of the semiconductor plastic packaging press detects that the product has been removed, the trigger mechanism is triggered, and the electronic control unit drives the moving assembly 30 to feed, driving the roller brush head assembly 40 to move to the middle position of the opened upper mold and the lower mold. At this time, the lifting part 42 starts, driving the two cleaning blocks 41 away from each other until the two cleaning blocks 41 are respectively against the upper mold or the lower mold, and the mold surface cooperates with the cleaning cavity 43 to form a closed cavity. Then, the dust brushing part 44 starts to operate to clean the dust and impurities on the mold surface. At the same time, the dust suction component 50 works to suck out and store the dust and impurities floating in the sealed cavity through the dust extraction duct assembly 60.
[0062] This embodiment adopts the technical means of cooperating with the moving component 30 and the roller brush head component 40. After each molding operation is completed, the moving component 30 is used to drive the two cleaning blocks 41 to approach the corresponding molds respectively, and automatically clean the dust and impurities thereon, and basically no missed cleaning phenomenon will occur. The technical problems of easy missed cleaning and high work intensity in manual cleaning are overcome, thereby achieving the technical effect of improving the yield rate and reducing the work intensity.
[0063] In a specific embodiment, the triggering part 23 includes a vertical plate 231 slidably arranged in the column 21, a force-bearing plate 232 is fixedly connected to the upper surface of the vertical plate 231, and a fitting groove for the force-bearing plate 232 to be embedded is provided on the upper surface of the column 21, and racks 233 are fixedly connected to both sides of the vertical plate 231, and a pair of parallel horizontal shafts 234 are rotatably connected in the column 21, and both ends of each horizontal shaft 234 are fixedly connected to the corresponding clamping block 22, and the middle part of the horizontal shaft 234 is fixedly connected to the gear 233. 5, each rack 233 is meshed with the corresponding gear 235, the clamping assembly 20 also includes a pair of symmetrically arranged columns 24 fixedly connected to the carrier 10, the upper end of the column 24 is fixedly connected to the cover 25, the cover 25 is fixedly installed on the top of the semiconductor plastic packaging press, each column 1 21 is fixedly connected to a cross column 26, the cross column 26 is fixedly connected to the corresponding column 24, the two clamping blocks 22 are locked by a U-shaped connecting plate 27, one of the clamping blocks 22 has a pair of parallel An extension plate 221 is set, and a corresponding position on the other clamping block 22 is provided with a card slot for the extension plate 221 to be embedded. Each extension plate 221 is threadedly connected with a fastening bolt 222, and a mounting groove is provided on the corresponding clamping block 22, and an internal thread matching the external thread on the fastening bolt 222 is provided in the mounting groove. A pair of vertical grooves are provided in the clamping block 22 with the card slot, and each vertical groove is concentrically arranged and communicated with the corresponding mounting groove, and an extrusion rod 223 is slidably provided in the vertical groove, and each extrusion rod The lower end of 223 has a convex portion, and a pair of relatively arranged force blocks 224 are slidably arranged in the clamping block 22 with a slot, and the cross-section of each force block 224 is arranged in a right-angle trapezoidal shape. The convex portion at the lower end of the extrusion rod 223 contacts and cooperates with the inclined surface of the corresponding force block 224, and the opposite sides of the two force blocks 224 are fixedly connected with a limiting rod 225, and a spring 226 is sleeved on the limiting rod 225. The symmetrical plate body of the U-shaped connecting plate 27 is penetrated by a limiting hole 227 for the limiting rod 225 to penetrate.
[0064] The working principle and beneficial effects of the above technical solution are:
[0065] During installation, first adjust the position of the support platform 10 and the column 21 thereon so that the column 21 moves to the bottom of the square tube at the upper beam of the plastic sealing press, and then move the support platform 10 upward so that the upper surfaces of the two columns 21 contact and squeeze the lower surface of the corresponding position of the square tube, and the force plate 232 on the column 21 is squeezed by the reaction force of the square tube, and the force plate 232 drives the vertical plate 231 to slide synchronously with the corresponding column 21 until the force plate 232 is embedded in the fitting groove on the column 21. During this process, the two racks 233 on the vertical plate 231 drive the corresponding gear 235 to rotate, so that the two gears 235 rotate in opposite directions, and the gear 235 drives the corresponding horizontal axis 234 to rotate synchronously, thereby driving the two clamping blocks 22 to embrace the square tube.
[0066] After the two clamping blocks 22 are closed, the two extension plates 221 on one of the clamping blocks 22 are inserted into the corresponding slots on the other clamping block 22, and then the fastening bolts 222 on the two extension plates 221 are tightened. Since the fastening bolts 222 are relatively long, their lower ends push the extrusion rods 223 downwards during the process of being screwed into the vertical slots. The convex parts at the lower ends of the two extrusion rods 223 respectively contact and squeeze the inclined surfaces of the corresponding force-bearing blocks 224, so that the two force-bearing blocks 224 move away from each other, the spring 226 is deformed, and the two limit rods 225 respectively penetrate into the U-shaped connecting The U-shaped connecting plate 27 is locked relative to the two clamping blocks 22 in the corresponding limiting holes 227 on the plate 27. At the same time, the U-shaped connecting plate 27, with the cooperation of the limiting rod 225, tightly clamps the two clamping blocks 22 to improve the stability of the clamping blocks 22 after being clamped together. Conversely, when disassembly is required, the two fastening bolts 222 are screwed out, and the two limiting rods 225 approach each other under the elastic force of the spring 226 and come out of the corresponding limiting holes 227. Then, the U-shaped connecting plate 27 is removed, and the two clamping blocks 22 are pried apart to both sides to release their clamping state.
[0067] It should be noted that the distance between the upper surface and the lower surface of the square tube is smaller than the distance between the top and the bottom of the clamping block 22, and the distance difference between the two is greater than the distance from the upper surface of the force block 224 to the upper surface of the column 21 when the clamping block 22 is not closed. At the same time, positioning holes are provided on the clamping block 22 and the square tube. After the supporting platform 10 is installed, the positioning holes on the clamping block 22 and the square tube can be fine-tuned to calibrate the position so that they are aligned, and then the positioning pins are inserted to further improve the accuracy of the device. This is a conventional prior art, so it is not described in detail.
[0068] The present embodiment adopts the technical means of cooperating the clamping assembly 20 and the square tube provided on the plastic packaging press. When installing the supporting platform 10, the reaction force when the upper sides of the two uprights 21 and the lower surface of the square tube are connected drives the force plate 232 on the upright 21 to move downward, thereby driving the two clamping blocks 22 to clamp together, and then manually locking, so that the supporting platform 10 is quickly installed on the plastic packaging press. Compared with the method of using multiple bolt connections in the prior art, this operation is simpler and more convenient, saves time and effort, and achieves the technical effect of improving installation efficiency.
[0069] At the same time, the support platform 10 and the cover plate 25 are further connected and fixed by the second column 24, and the horizontal column 26 connects and fixes the first column 21 and the corresponding second column 24, which has a further reinforcement effect, so that the device can be stably installed on the semiconductor plastic packaging press.
[0070] It should be noted that the clamping block 22 on the device can be compatible with various types of semiconductor plastic packaging presses, such as 250T / 450T / 600T, etc., which expands the adaptability of the device and further improves the practicability of the device.

[0072] The working principle and beneficial effects of the above technical scheme are as follows: the servo motor 31 provides power to drive the wheel axle 32 and the synchronous wheel 33 to rotate, thereby driving the synchronous belt 34 and the moving block 354 and the engaging plate 355 thereon to move synchronously; the moving block 354 drives the L-shaped bracket 352 connected thereto to move synchronously; the L-shaped bracket 352 is restricted in its movement trajectory by the cooperation of the slide rail 351 and the slider 353, and can only move back and forth along the length direction of the slide rail 351, thereby driving the extension frame 356 and the roller brush head assembly 40 thereon to move synchronously, thereby realizing the feeding and retraction of the roller brush head assembly 40, and the positioning is accurate and reliable.
[0073] In a specific embodiment, the lifting part 42 includes a pair of symmetrically arranged mounting frames 421, each mounting frame 421 is fixedly connected to the corresponding cleaning block 41, a lifting cylinder 422 is fixedly connected to the corresponding position of the extension frame 356, and the moving end of the lifting cylinder 422 is fixedly connected to the corresponding mounting frame 421, and the dust brush part 44 includes a spiral brush 441 rotatably arranged in the cleaning chamber 43, and each cleaning block 41 is fixedly connected to a speed regulating motor 442, and the output shaft of the speed regulating motor 442 is fixedly connected to the central axis of the corresponding spiral brush 441, and each cleaning block 41 is provided with a blowing part 45, and the blowing part 45 includes multiple A blowing block 451 is fixedly connected to the cleaning block 41, and a plurality of equidistant blowing channels are provided on the blowing block 451, and the blowing channels are inclined.

[0074] The working principle and beneficial effects of the above technical solution are as follows: after each mold brushing is completed, the lifting cylinder 422 drives the corresponding cleaning block 41 to move, so that the two cleaning blocks 41 move away from each other, until the soft silicone skins 46 on the two cleaning blocks 41 are pressed against the corresponding upper mold or lower mold, and the cleaning cavity 43 cooperates with the corresponding mold surface to form a sealed cavity. At this time, the blowing block 451 starts to blow air to lift the dust on the mold, and the speed regulating motor 442 drives the spiral brush 441 to rotate to gather the dust particles to the middle position close to the side of the dust extraction pipe assembly 60, and at the same time, the dust suction assembly 50 is turned on to suck out the dust, thereby realizing the mold blowing-sweeping-suction cleaning function.

[0075] In a specific embodiment: the dust collection component 50 includes a dust collecting box 51, on the top of which a dust extraction fan 52 is fixedly installed and connected thereto, at least one dust collecting box 53 is detachably installed on the inner bottom of the dust collecting box 51, a filter element 54 is arranged directly above the dust collecting box 53, a partition 55 is fixedly connected inside the dust collecting box 51, the filter element 54 is fixedly connected to the lower surface of the partition 55, and a dust inlet hole connected to the filter element 54 is penetrated through the partition 55, a back-blowing air storage tank 56 is fixedly connected to the upper surface of the partition 55, and a back-blowing pulse valve 57 corresponding to the number of the filter element 54 is installed on the back-blowing air storage tank 56, and an electric butterfly valve 58 corresponding to the number of the dust collecting box 53 is fixedly connected to the outer side of the dust collecting box 51 and connected thereto.
[0076] The working principle and beneficial effects of the above technical solution are as follows: the dust extraction fan 52 works to suck dust impurities into the dust collecting box 51 through the electric butterfly valve 58, and the dust impurities are blocked by the filter element 54, and most of them fall into the dust collecting box 53, completing the collection of dust impurities. At regular intervals, the back-blowing pulse valve 57 on the back-blowing air storage tank 56 is opened, and the positive pressure gas in the back-blowing air storage tank 56 is released to blow away the dust attached to the filter element 54, causing it to fall into the dust collecting box 53, completing the self-cleaning of the filter element 54. When there is a lot of dust in the dust collecting box 53, it can be taken out and cleaned.

[0078] The working principle and beneficial effects of the above technical solution are as follows: when three blowing blocks 451 are set to cooperate with the four-way pipe joint 455, the installation of the air supply pipe 453 is relatively convenient and not prone to bending. A high-pressure air pump can be externally connected to the pipe port of the four-way pipe joint 455 that is not connected to the air supply pipe 453. After the airflow output by the high-pressure air pump is transported to the air supply pipe 453, it is ejected from the multiple blowing channels on the multiple blowing blocks 451 to blow up the dust impurities on the corresponding mold surfaces. By setting the electric butterfly valve 58 to two, one-to-two can be achieved, that is, one dust extraction fan 52 corresponds to two sets of mold brushing equipment. This can be achieved by controlling the valve switch of the electric butterfly valve 58. When one of the mold brushing equipment is working and the other is not working, the dust extraction fan 52 is turned on, and the electric butterfly valve 58 can be turned on and off by one. When the mold brushing equipment is not working, the dust extraction fan 52 is turned off, which is energy-saving and environmentally friendly. The setting of the explosion-proof electrical box 59 can improve the safety of the device.
[0079] In a specific embodiment: the dust extraction duct assembly 60 includes a main pipe 61, the end of the main pipe 61 away from the exhaust duct cavity 452 is connected to the corresponding electric butterfly valve 58, the end of the main pipe 61 close to the exhaust duct cavity 452 is sealed, and a pair of parallel inner tubes 62 are fixedly connected to the side of the tube body, and a corresponding number of outer tubes 63 are fixedly connected to the L-shaped bracket 352, each outer tube 63 is slidably matched with the corresponding inner tube 62, and the end of the outer tube 63 away from the L-shaped bracket 352 is connected to the corresponding exhaust duct cavity 452.
[0080] The working principle and beneficial effects of the above technical solution are as follows: when the moving component 30 moves, the inner tube 62 and the outer tube 63 slide relative to each other, and while completing the dust extraction work, it does not affect the feeding and retraction of the roller brush head assembly 40. The dust impurities in the cleaning block 41 are first discharged through the exhaust pipe cavity 452, and then collected into the main tube 61 through the two inner tubes 62 and the outer tube 63, and finally transported to the dust extraction fan 52.
[0081] In a specific embodiment, the trigger mechanism is configured as an electric control box 70 , and the electric control box 70 is fixedly mounted on the upper surface of the supporting platform 10 .
[0082] The working principle and beneficial effects of the above technical solution are as follows: a control program is pre-set in the electrical control box 70 to control the start-up and shutdown sequence and time of the servo motor 31, the dust extraction fan 52, the lifting cylinder 422, the speed regulating motor 442, the wind knife 454 and the external high-pressure air pump, so as to realize the automated operation of the device. At the same time, the independent electrical control box 70 has the advantages of neat wiring, safety and reliability, and easy disassembly and assembly.
[0083] In a specific embodiment: it also includes a rear protective cover assembly 80, which is arranged on the back side of the semiconductor molding press. The rear protective cover assembly 80 includes a detachable cover shell 81 installed on the back side of the semiconductor molding press. A pair of symmetrically arranged protective doors 82 are hinged on the cover shell 81, and each protective door 82 is provided with an observation window 83, and the observation window 83 is set to a transparent material.
[0084] The working principle and beneficial effects of the above technical solution are as follows: the cover 81 has a safety protection function to prevent the movement of the mold brushing equipment from causing harm to personnel, the observation window 83 is convenient for the staff to observe the working conditions of the mold brushing equipment, and the protective door 82 is convenient for the maintenance of the mold brushing equipment.
[0085] In a specific embodiment: it also includes a safety detection component 90, which is arranged on the front side of the semiconductor molding press. The safety detection component 90 includes a pair of symmetrically arranged support frames 91 and opposing photoelectric devices 92. Each support frame 91 is fixedly connected to the semiconductor molding press. The light-emitting end and the photosensitive end of the opposing photoelectric device 92 are respectively fixedly installed on the opposite sides of the two support frames 91.
[0086] The working principle and beneficial effects of the above technical solution are as follows: the reflected photoelectric device 92 senses the handle of the product bracket to determine whether there is material on the mold, and the original light curtain on the press determines whether there is a human hand entering the machine. The roller brush head assembly 40 is allowed to enter the mold only after dual detection and determination by the reflected photoelectric device 92 and the safety light curtain. For example, only when the bracket is taken away and the reflected photoelectric device 92 is not blocked, it is determined that there is no material on the mold. At the same time, the safety light curtain is not triggered, and it is determined that no human hand has entered the machine and the bracket has been completely removed, the roller brush head assembly 40 can enter to clean the mold. After cleaning, the roller brush head assembly 40 is returned, and manual feeding can continue. If any of the safety light curtain and the reflected photoelectric device 92 is triggered in the middle, the roller brush head assembly 40 will suspend its action and can only continue to act after the abnormality is resolved, thereby ensuring safety.
[0087] Working principle:
[0088] First, two upright posts 21 are connected and fixed to the square passage on the upper beam of the semiconductor plastic packaging press by means of the clamping assembly 20, so that the device is stably installed on the semiconductor plastic packaging press.
[0089] Then, after each mold brushing is completed, the safety light curtain and the reflected photoelectric 92 of the semiconductor plastic sealing press detect that the product bracket has been moved out, and the electric control box 70 drives the servo motor 31 to rotate, driving the wheel shaft 32 and the synchronous wheel 33 to rotate, and then driving the synchronous belt 34 and the moving block 354 and the meshing plate 355 thereon to move synchronously. The moving block 354 drives the L-shaped bracket 352 connected to it to move synchronously. When the L-shaped bracket 352 moves, the inner tube 62 and the outer tube 63 slide relative to each other. While completing the dust extraction work, it does not affect the feeding and retraction of the roller brush head assembly 40. The L-shaped bracket 352 is restricted in its movement trajectory under the cooperation of the slide rail 351 and the slider 353, and can only move back and forth along the length direction of the slide rail 351, thereby driving the extension frame 356 and the roller brush head assembly 40 thereon to move synchronously, realizing the feeding of the roller brush head assembly 40 and driving the roller brush The head assembly 40 moves to the middle position between the opened and closed upper and lower molds, and the lifting cylinder 422 drives the corresponding cleaning block 41 to move, so that the two cleaning blocks 41 move away from each other, and the two cleaning blocks 41 are respectively against the upper mold or the lower mold, and the mold surface cooperates with the cleaning cavity 43 to form a closed cavity. At this time, the blowing block 451 starts to blow air to lift the dust on the mold, and the speed regulating motor 442 drives the spiral brush 441 to rotate to gather the dust particles to the middle position close to the side of the dust extraction pipe assembly 60. At the same time, the dust suction assembly 50 is turned on to suck out the dust, realizing the mold blowing-sweeping-suction cleaning function. During this process, the moving assembly 30 drives the cleaning block 41 to move along the length direction of the slide rail 351, so that it can cover the entire mold surface and comprehensively clean the mold surface. Finally, the wind knife 454 blows the mold surface once, and the double cleaning eliminates cleaning omissions and dead corners, thereby completing the entire cleaning action.
[0090] At the same time, the dust extraction fan 52 works, and the dust impurities in the cleaning block 41 are first discharged through the exhaust pipe cavity 452, and then collected in the main pipe 61 through two inner tubes 62 and the outer tube 63, and finally sucked into the dust collecting box 51 through the electric butterfly valve 58. The dust impurities are blocked by the filter element 54, and most of them fall into the dust collecting box 53. The filtered air is discharged from the air outlet on the dust extraction fan 52 to complete the collection of dust impurities. At regular intervals, the back-blowing pulse valve 57 on the back-blowing air storage tank 56 is opened, and the positive pressure gas in the back-blowing air storage tank 56 is released to purge the dust attached to the filter element 54, completing the self-cleaning of the filter element 54. When there is a lot of dust in the dust collecting box 53, it can be taken out and cleaned.
[0091] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
