Description

Technical Field

[0001] This invention belongs to the field of integrated circuit manufacturing technology, and specifically relates to an integrated circuit testing and packaging machine. Background Technology

[0002] Integrated circuit manufacturing is a complex process of integrating electronic components such as transistors, resistors, and capacitors, along with their interconnections, onto semiconductor wafers to ultimately form miniature circuits with specific functions. After integrated circuit manufacturing, test tape and reel equipment is required. This equipment is a key component in the semiconductor back-end packaging and testing process, primarily used for electrical performance testing of chip pins and tape and reel packaging. It is suitable for the chip packaging process of small outline integrated circuits. Existing gravity-type test tape and reel machines rely on the weight of the chip to feed it from a height, using customized slides and interception structures to systematically complete the integrated circuit testing and packaging work. While this can meet the needs of daily production, the connection between the packaging and testing parts of the test tape and reel equipment is a guide-type slide dock. Although it can facilitate process transitions, the sliding integrated circuit is prone to collisions at corners, causing misalignment. Misaligned integrated circuits can lead to packaging abnormalities, thus affecting the packaging stability of the test tape and reel equipment. At the same time, the vision inspection structure before packaging is fixed on a bracket, allowing only single-directional visual inspection from the vertical direction, resulting in blind spots that cannot be monitored, affecting the accuracy of inspection. Therefore, designing an integrated circuit test tape and reel machine is essential. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated circuit test tape and reel machine with a simple structure and reasonable design in order to solve the above problems.

[0004] The present invention achieves the above objectives through the following technical solutions: An integrated circuit test tape and reel machine includes a bottom support, a feeding bracket on the bottom support, an automatic feeding mechanism on the feeding bracket, a pin testing mechanism on one side of the feeding bracket, a packaging mechanism and a process conversion mechanism on the bottom support, and a multi-angle vision inspection mechanism on the process conversion mechanism.

[0005] As a further optimization of the present invention, the automatic feeding mechanism includes a material rack fixed to the top of the feeding bracket. A material transfer platform is slidably connected to the top of the feeding bracket, and a pusher arm is rotatably connected to the bottom of the material transfer platform. The pusher arm is rotatably connected to the feeding bracket, and one end of the pusher arm is rotatably connected to the output end of a pusher cylinder. The pusher cylinder is fixed in the feeding bracket. A top-loading cylinder is symmetrically arranged at the top of the inside of the feeding bracket, and a tilting cylinder is rotatably connected to the inside of the feeding bracket. A pressure platform is rotatably connected to the output end of the tilting cylinder. A pressure cylinder is arranged on the pressure platform, and the pressure platform is rotatably connected to a docking bracket. A first sliding table is arranged between the docking brackets.

[0006] As a further optimization of the present invention, the pin testing mechanism includes a sliding motor symmetrically arranged on the feeding bracket, a belt roller assembly is provided on the output end of the sliding motor, a sliding stage is provided on the belt roller assembly, a first cylinder is symmetrically arranged on the sliding stage, a second cylinder is symmetrically arranged on the top of the feeding bracket, and a pin clamp is fixedly connected to the output end of the second cylinder.

[0007] As a further optimization of the present invention, a second slide is provided on the feeding bracket, and a limit cylinder is provided on one side of both the second slide and the first slide, and a limit component is provided at the output end of the limit cylinder.

[0008] As a further optimization of the present invention, the process conversion mechanism includes a lead screw motor fixed on the bottom support, a sliding lead screw fixedly connected to the output end of the lead screw motor, a support platform provided on the sliding lead screw, the support platform being slidably connected to the bottom support, and a support frame fixedly connected to the top of the support platform.

[0009] As a further optimization of the present invention, a rotary motor is slidably connected to the support frame, the rotary motor is fixedly connected to the output end of the adjusting cylinder, the adjusting cylinder is fixed to the support frame, a clamping cylinder is fixedly connected to the output end of the rotary motor, a material clamping cylinder is fixedly connected to the output end of the clamping cylinder, and a material clamping rod is fixedly connected to the output end of the material clamping cylinder.

[0010] As a further optimization of the present invention, the multi-angle visual inspection mechanism includes a mounting frame fixedly connected to an adjusting cylinder, a detection bracket is provided on the mounting frame, and a mounting plate is rotatably connected to the detection bracket.

[0011] As a further optimization of the present invention, the mounting plate is fixedly connected to the output end of the adjusting motor, the adjusting motor is fixed in the mounting frame, a vision camera is fixedly mounted on the mounting plate, and the vision camera is slidably connected in the detection bracket.

[0012] The beneficial effects of this invention are as follows: This invention utilizes a process conversion mechanism to actively clamp the integrated circuit (IC) after pin testing. During this process, the IC slides down a second slide. An adjusting cylinder drives a rotary motor and a clamping cylinder to approach the second slide, intercepting the IC between two clamping rods. Subsequently, the clamping cylinder drives a material clamping cylinder to approach, clamping the IC through the two clamping rods. The adjusting cylinder then returns the clamping cylinder to its original position. A lead screw motor drives a sliding lead screw to rotate, moving the support platform along the axis of the sliding lead screw. Simultaneously, the rotary motor drives the clamping cylinder to rotate, moving the IC to the loading position of the packaging mechanism. Then, the two clamping cylinders simultaneously move the clamping rods downwards, placing the IC into the packaging mechanism. This replaces the existing sliding material transfer process, preventing the IC from tilting due to collisions at corners and ensuring the packaging stability of the equipment.

[0013] This invention utilizes a rotary motor to drive a clamping cylinder during the clamping and transfer of integrated circuits. Simultaneously, the cylinder pulls the rotary motor closer to the inspection bracket, moving the integrated circuit between the clamping rods to the center of the inspection bracket. Subsequently, visual inspection is performed using a vision camera. During the inspection process, the motor drives the mounting plate to rotate, adjusting the position of the vision camera relative to the integrated circuit. This eliminates blind spots in visual inspection and improves the accuracy of the inspection. Attached Figure Description

A pin testing mechanism 4 is located on one side of the feeding bracket 2 and is located on the inclined surface of one side of the feeding bracket 2. After the integrated circuit is fed by the automatic feeding mechanism 3, it will slide down the inclined surface on the feeding bracket 2 under the action of gravity. During the sliding process, the pin testing mechanism 4 performs limiting and testing. A packaging mechanism 5 and a process conversion mechanism 6 are respectively provided on the bottom support 1. The process conversion mechanism 6 is used to put the tested integrated circuit into the packaging mechanism 5. The hot pressing structure in the packaging mechanism 5 can package the integrated circuit placed in the plastic shell. After packaging, tape and reel are performed. A multi-angle vision inspection mechanism 7 is provided on the process conversion mechanism 6. The multi-angle vision inspection mechanism 7 can perform visual inspection of the integrated circuit from multiple angles before packaging and tape. The automatic feeding mechanism 3 includes a material rack 31 fixed to the top of the feeding support 2. The material rack 31 includes symmetrical guide frames, and a material tube for placing integrated circuits is arranged between the guide frames. A transfer platform 32 is slidably connected to the top of the feeding support 2. A pusher arm 33 is rotatably connected to the bottom of the transfer platform 32. The pusher arm 33 is rotatably connected to the feeding support 2, and one end of the pusher arm 33 is rotatably connected to the output end of a pusher cylinder 34. The pusher cylinder 34 is selected according to the actual use and is fixed in the feeding support 2. The pusher cylinder 34 can drive the pusher arm 33 to swing, thereby pulling the transfer platform 32 to slide during the swing. The transfer platform 32 has a groove to restrict the movement of the material tube. A top-loading cylinder 35 is symmetrically arranged at the top of the inside of the feeding support 2. The top-loading cylinder 35 is selected according to the actual use. 5. Support the vertically stacked tubes from below. When feeding is required, the top cylinder 35 lowers the tubes so that the bottom tube is embedded in the groove on the transfer table 32. The feeding bracket 2 is rotatably connected to the inside of the rotating cylinder 36. The rotating cylinder 36 is selected according to the actual use. The output end of the rotating cylinder 36 is rotatably connected to the pressing table 37. The pressing table 37 is equipped with a pressing cylinder 38. The pressing cylinder 38 is selected according to the actual use. The pressing table 37 is rotatably connected to the docking bracket 39. A first slide 8 is set between the docking brackets 39. When the tubes move to one side of the pressing table 37 as the transfer table 32 moves, the pressing cylinder 38 presses down to hold one end of the tube. Then the output end of the rotating cylinder 36 extends, driving the pressing table 37 to rotate around the docking bracket 39, and putting the integrated circuit in the tube into the first slide 8. The pin testing mechanism 4 includes a sliding motor 41 symmetrically arranged on the loading bracket 2. A belt roller assembly is provided at the output end of the sliding motor 41. The rollers in the belt roller assembly are rotatably connected to the loading bracket 2. The belt wraps around the rollers and the drive wheel at the output end of the sliding motor 41. A sliding platform 42 is fixed on the belt. A first cylinder 43 is symmetrically arranged on the sliding platform 42. A housing for supporting integrated circuits is provided in the sliding platform 42. After the integrated circuit falls into the housing, it is limited by the first cylinder 43 to prevent it from falling out of the bottom of the housing. A second cylinder 44 is symmetrically arranged on the top of the loading bracket 2. A pin clamp 45 is fixedly connected to the output end of the second cylinder 44. The first cylinder 43 and the second cylinder 44 are selected according to the actual application. When the integrated circuit falls between the second cylinders 44, the cylinders arranged on the loading bracket 2 limit the integrated circuit and intercept it at the test position. Then, the second cylinders 44 drive the pin clamps 45 on both sides to approach and connect with the pins of the integrated circuit for testing. The loading bracket 2 is equipped with a second slide 9, and both the second slide 9 and the first slide 8 are equipped with a limit cylinder 46 on one side. The output end of the limit cylinder 46 is equipped with a limit element 47. The limit cylinder 46 is selected according to the actual use. After the pin test, the integrated circuit will enter the second slide 9. During the fall, the limit cylinder 46 drives the limit element 47 to move down to temporarily limit the integrated circuit. When the process needs to be transferred, the limit cylinder 46 drives the limit element 47 to move up, so that the integrated circuit continues to slide down. The process conversion mechanism 6 includes a lead screw motor 61 fixed on the bottom support 1. The lead screw motor 61 is selected according to the actual use. The output end of the lead screw motor 61 is fixedly connected to a sliding lead screw 62. A support platform 63 is provided on the sliding lead screw 62. The support platform 63 is connected to the sliding lead screw 62 through an internal ball nut. The lead screw motor 61 drives the sliding lead screw 62 to rotate, which can drive the support platform 63 to move along the axis of the sliding lead screw 62. The support platform 63 is slidably connected to the guide rail provided on the bottom support 1. A support frame 64 is fixedly connected to the top of the support platform 63. The support frame 64 slides within the support platform 64. A rotary motor 65 is connected, and the appropriate model of the rotary motor 65 is selected according to the actual use. The rotary motor 65 is fixedly connected to the output end of the adjusting cylinder 66, which is fixed to the support frame 64. The adjusting cylinder 66 is also selected according to the actual use. The sliders on both sides of the rotary motor 65 are slidably connected to the guide rails on the inner wall of the support frame 64. A cylinder bracket is fixedly connected to the output end of the rotary motor 65, and a clamping cylinder 67 is fixed in the cylinder bracket. The appropriate model of the clamping cylinder 67 is selected according to the actual use. A material clamping cylinder 68 is fixedly connected to the output end of the clamping cylinder 67. The clamping cylinder 67 can drive two clamping cylinders 67 to move closer to each other. The output end of the clamping cylinder 68 is fixedly connected to the clamping rod 69. When the integrated circuit slides down the second slide table 9, the adjusting cylinder 66 drives the rotary motor 65 and the clamping cylinder 67 to move down, intercepting the integrated circuit between the two clamping rods 69. Then the clamping cylinder 67 drives the clamping cylinder 68 to move closer, and the integrated circuit is clamped by the two clamping rods 69. The multi-angle visual inspection mechanism 7 includes a mounting frame 71 fixedly connected to the adjusting cylinder 66. A detection bracket 72 is provided on the mounting frame 71. A mounting plate 73 is rotatably connected to the detection bracket 72. The output end of the adjusting motor 75 is fixedly connected to the mounting plate 73. The adjusting motor 75 is fixedly installed in the mounting frame 71. A visual camera 74 is fixedly installed on the mounting plate 73. During the process of the adjusting motor 75 driving the mounting plate 73 to rotate, the visual camera 74 on the mounting plate 73 can slide in the detection bracket 72.

[0018] It should be noted that, in use, this integrated circuit testing tape and reel machine first stacks the tubes containing integrated circuits sequentially between the material racks 31 at the top of the loading bracket 2. When loading is required, the top-loading cylinder 35 lowers the tubes, causing the bottom tube to embed into the groove on the transfer table 32. Then, the pushing cylinder 34 drives the pushing arm 33 to swing, which in turn pulls the transfer table 32 to slide. As the transfer table 32 moves, the tubes move to one side of the pressing table 37, where the pressing cylinder 38 presses down to hold one end of the tube. Then, the output end of the flipping cylinder 36 extends, causing the pressing table 37 to rotate around the docking bracket 39, putting the integrated circuit in the tube into the first slide table 8. During the process, the limiting cylinder 46 on one side of the first slide table 8 provides a limiting function. To prevent material accumulation, the integrated circuits slide down independently and sequentially under the interception action of the limiting cylinder 46, sliding into the housing on the sliding stage 42. There, the first cylinder 43 then limits the movement, preventing the integrated circuits from detaching from the bottom of the housing. Subsequently, the sliding motor 41 drives the belt roller assembly, moving the sliding stage 42 to the pin testing area. At this point, the first cylinder 43 releases its interception of the integrated circuit, allowing it to enter the testing area. Simultaneously, the cylinders on the loading bracket 2 limit the movement, stopping the integrated circuit at the testing position. Then, the second cylinder 44 moves the pin clamps 45 on both sides closer to engage the pins of the integrated circuit for testing. After testing, the second cylinder 44 returns to its original position, and the cylinder used to stop the integrated circuit also returns to its original position. The integrated circuit enters the second slide 9 from the testing area and is limited by the limiting cylinder 46 on one side of the second slide 9 to prevent material accumulation. Then, under the interception action of the limiting cylinder 46, the integrated circuit slides down independently and sequentially. As the integrated circuit slides down the second slide 9, the adjusting cylinder 66 drives the rotary motor 65 and the clamping cylinder 67 to move downwards, intercepting the integrated circuit between the two clamping rods 69. Subsequently, the clamping cylinder 67 drives the clamping cylinder 68 to approach, clamping the integrated circuit through the two clamping rods 69. Then, the rotary motor 65 drives the clamping cylinder 67 to rotate, while the adjusting cylinder 66 pulls the rotary motor 65 closer to the detection bracket 72, moving the integrated circuit between the clamping rods 69 to the center of the detection bracket 72. Then, visual inspection is performed using a vision camera 74. Simultaneously, during the inspection process, an adjusting motor 75 drives the mounting plate 73 to rotate. This rotation adjusts the position of the vision camera 74 relative to the integrated circuit, eliminating blind spots and improving inspection accuracy. After the visual test, a rotary motor 65 drives the clamping cylinder 67 to rotate and return to its original position. Simultaneously, an adjusting cylinder 66 drives the clamping cylinder 67 to return to its original position. A lead screw motor 61 drives the sliding lead screw 62 to rotate, causing the support platform 63 to move along the axis of the sliding lead screw 62. At the same time, the rotary motor 65 drives the clamping cylinder 67 to continue rotating, moving the integrated circuit to the loading position of the packaging mechanism 5. Then, two clamping cylinders 68 simultaneously drive the clamping rod 69 to move downwards, placing the integrated circuit into the packaging mechanism 5.The thermoforming structure in packaging mechanism 5 can encapsulate the integrated circuit placed in the plastic casing, and then the package is reeled in and wound up.

[0019] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
