Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, and in particular to an automatic feeding mechanism for chip carrier trays. Background Technology

[0002] In automated packaging and testing production lines for semiconductor chips, chip carriers serve as crucial carriers for supporting and protecting the chips during transport. The stability and positional accuracy of their feeding directly impact the overall production line's operational efficiency. Traditional automated feeding methods typically use a dropping mechanism to separate stacked chip carriers one by one and place them on a conveyor line, which then transports them to the next process for inspection or processing.

[0003] However, in actual production, because the chip carrier trays are usually made of anti-static plastic and are lightweight, they are prone to uncontrollable lateral slippage or rotational deflection on the conveyor belt when they fall from the unloading mechanism onto the conveyor belt surface due to the effects of gravity and the instantaneous reaction force upon contact. This random positional deviation makes it difficult for the carrier tray to accurately enter the subsequent inspection station or the gripping position of the robotic arm. This can cause equipment alarms and shutdowns at best, and at worst, lead to missed chip detection or damage from mechanical crushing. Existing solutions attempt to add guide rails, but rigid rails not only fail to eliminate small angular deflections, but also often fail to provide active centering correction force when facing carrier trays of different sizes, making it difficult to meet the consistency requirements of material position in high-precision automated production lines.

[0004] Therefore, this utility model proposes an automatic feeding mechanism for chip carrier disks to overcome the shortcomings of the prior art. Utility Model Content

[0005] In the existing technology, during the process of placing the chip carrier tray from the unloading mechanism onto the conveyor belt, the carrier tray is easily affected by gravity and contact reaction force, causing positional displacement or rotation, which makes it difficult for subsequent processes to accurately grasp or detect it. The present invention aims to provide an improved chip carrier tray automatic feeding mechanism that can effectively solve the above problems.

[0006] This utility model provides an automatic chip carrier tray feeding mechanism, including: a frame, a conveyor belt disposed on the top of the frame, a dropping mechanism located above the conveyor belt, and a correction mechanism disposed on the top of the frame and located on both sides of the conveyor belt.

[0007] The correction mechanism has a precise linkage transmission structure, including a mounting plate symmetrically rotatably connected to the frame. The mounting plate is rotatably engaged with the frame via a rotating shaft. A drive assembly is fixedly mounted on the frame. The drive assembly drives and connects to a connecting block. Connecting blocks are rotatably connected to both ends of the connecting block. One end of a connecting rod is rotatably connected to the connecting block. The other end of the connecting rod is rotatably connected to a mounting block. The mounting block is fixedly mounted on the side of the mounting plate near the rotating shaft.

[0008] Furthermore, a correction block is provided at the end of the mounting plate away from the rotation axis, and a correction plate is provided on the side of the correction block facing the center of the conveyor belt. A spring post is connected between the correction block and the correction plate. A spring is sleeved on the outer periphery of the spring post. The correction plate forms a buffer structure by squeezing the spring post and the spring. The driving component drives the connecting block to slide, and drives the mounting plate to rotate around the rotation axis through the connecting rod, so that the correction plate moves inward in a flexible contact manner to correct the position of the chip board.

[0009] Preferably, the drive assembly is designed as follows: it includes a fixed block fixedly connected to the frame and a slide rail fixedly mounted on the frame. The slide rail has a groove inside, and a slider is slidably fitted in the groove. A connecting block is fixedly connected to the top of the slider. A hydraulic cylinder is connected between the fixed block and the connecting block. The connecting block is driven by the hydraulic cylinder. The hydraulic shaft of the hydraulic cylinder retracts, causing the connecting block to slide linearly back and forth along the groove, thereby ensuring a stable output of driving force.

[0010] Preferably, the feeding mechanism adopts a dual-cylinder collaborative feeding structure, including opposing limiting plates, forming a feeding channel between the limiting plates for accommodating the chip board, a lifting cylinder is provided below the feeding channel, the lifting cylinder is used to push the chip board out from inside the limiting plates, and a telescopic cylinder is provided outside the limiting plates, the extension end of the telescopic cylinder extends into the feeding channel to support the upper chip board and assist the lifting cylinder in completing the single-chip separation action.

[0011] Preferably, the bottom of the limiting plate is connected to an adjustment mechanism for quickly adjusting the width between the limiting plates to accommodate products of different specifications. The adjustment mechanism includes a base plate fixedly installed on the top of the frame, and a connecting column is fixedly provided at the bottom of the limiting plate.

[0012] Furthermore, the internal structure of the connecting column is a self-locking adjustment structure with a blind hole inside. The blind hole houses a second spring and a limiting bead. One end of the second spring abuts against the bottom of the blind hole, and the other end abuts against the limiting bead. The limiting bead extends out of the connecting column under the action of the second spring.

[0013] Preferably, the upper surface of the base plate is provided with a plurality of linearly arranged limiting grooves. The limiting bead can be inserted into the limiting groove by the elastic force of the second spring to fix the position of the limiting plate. When adjustment is required, the limiting plate is slid, and the limiting bead is compressed and retracts into the connecting column until it moves to the preset position, releases the pressure and enters the corresponding limiting groove, thereby achieving rapid positioning and anti-displacement.

[0014] Preferably, a detection element and a dust removal element are arranged sequentially above the conveyor belt and behind the unloading mechanism. The detection element is arranged in a gate shape above the conveyor belt for visual or position detection of the chip board, and the dust removal element is installed on the side for surface cleaning of the qualified chip board.

[0015] Preferably, a control element is fixedly installed on the rear side of the frame. The control element is electrically connected to the conveyor belt, the material feeding mechanism, the correction mechanism, the detection element, and the dust removal element to achieve automated integrated control.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting a correction mechanism on both sides of the conveyor belt, uses a hydraulic cylinder to drive the slider to make linear motion, and drives the mounting plates on both sides to swing inward synchronously through a linkage mechanism, so that the correction plate with a buffer structure can automatically center and correct the chip board on the conveyor belt. This solves the problem that the existing chip carrier tray is prone to positional deviation during the loading and unloading process, which affects the accuracy of subsequent processing or inspection processes. It achieves the technical effect of ensuring that the chip board is in the preset accurate conveying position and improving the accuracy and stability of automated processing of the production line.

[0018] 2. This utility model solves the problem that rigid correction mechanisms are prone to causing physical damage to fragile or lightweight chip carriers at the moment of contact by setting a spring column and spring buffer structure between the correction block and the correction plate, and using the elastic deformation of the spring to absorb the impact force when the correction plate contacts the chip board. It achieves the technical effect of flexibly protecting the workpiece while realizing accurate correction, and reducing the product scrap rate and process error rate.

[0019] 3. This utility model, by setting an adjustment mechanism including a spring and a limiting bead at the bottom of the limiting plate, and cooperating with multiple limiting grooves preset on the base plate, realizes the elastic locking adjustment of the spacing between the limiting plates. It solves the problem that the existing limiting device is cumbersome to adjust when adapting to different specifications of chip boards and is prone to displacement in a vibration environment. It achieves the technical effect of quickly adapting to the production switching of multiple specifications of products and ensuring that the limiting plate is stable and does not shift during the feeding process.

[0020] 4. This utility model, through the coordinated operation of the lifting cylinder and the telescopic cylinder in the feeding mechanism, uses the telescopic cylinder to support the upper chip board and the lifting cylinder to receive and lower the lower chip board, which solves the problem of multiple chips falling together or jamming in the traditional gravity feeding method. It achieves the technical effect of accurate and stable separation and feeding of a single chip board, and improves the reliability of the feeding device. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Example:

[0032] Reference Figures 1 to 7 This utility model provides an automatic feeding mechanism for a chip carrier tray, which aims to solve the technical problems of existing chip boards 32 being prone to positional displacement when falling onto the conveyor belt 2 during the feeding process, which affects the subsequent processing accuracy, and existing feeding limit devices being difficult to quickly adapt to chip boards 32 of different specifications and being prone to displacement after adjustment.

[0033] The main structure of the automatic chip tray feeding mechanism includes a frame 1, which serves as the mounting base for the entire device and provides a stable support platform for each functional component. A conveyor belt 2 is fixedly installed on the top of the frame 1, extending along the length of the frame 1 to transport the chip boards 32 supported on its surface from the loading end to the unloading end. A dropping mechanism 3 is installed above the starting end of the conveyor belt 2. The dropping mechanism 3 mainly consists of a limiting plate 31, a telescopic cylinder 33, and a lifting cylinder 34, which is used to separate the stacked chip boards 32 one by one and place them stably on the surface of the conveyor belt 2.

[0034] A correction mechanism 4 is provided at the top of the frame 1 and on both sides of the conveyor belt 2. Located on both sides of the conveyor belt 2, the correction mechanism 4 automatically aligns and corrects the chip board 32 after it has been unloaded, eliminating positional deviations during the loading process, through the linkage of a mechanical linkage structure. The correction mechanism 4 includes a drive assembly 47 fixedly mounted on the frame 1, and transmission components such as a connecting block 46, a connecting rod 45, and a mounting plate 41 driven by the drive assembly 47. The components are tightly fitted together to ensure the synchronicity and accuracy of the correction action.

[0035] Along the conveyor belt 2, a detection element 6 and a dust removal element 7 are arranged sequentially behind the unloading mechanism 3. The detection element 6, in a gate-shaped frame structure, spans above the conveyor belt 2 and is used to detect the appearance quality or positional status of the chip boards 32 passing below. The dust removal element 7 is fixedly installed on the side of the conveyor belt 2, with its output end facing the workpiece area on the conveyor belt 2, and is used to perform surface dust removal treatment on the qualified chip boards 32 to prevent dust from affecting subsequent processes.

[0036] A control element 8 is fixedly installed on the rear side of the frame 1. The control element 8 serves as the human-machine interface and electrical control center. It is electrically connected via wires to the conveyor belt 2, the cylinder assembly in the unloading mechanism 3, the drive assembly 47 in the correction mechanism 4, the detection element 6, and the dust removal element 7, respectively, enabling centralized control and status monitoring of the entire automatic feeding process. Through the coordinated operation of these mechanisms, the device achieves a fully automated feeding process from feeding, correction, detection, to dust removal.

[0037] The correction mechanism 4 includes two mounting plates 41 symmetrically arranged on the frame 1. The mounting plates 41, as the main swing components, are rotatably connected to the top of the frame 1 via a rotating shaft 42, allowing the mounting plates 41 to reciprocate horizontally around the axis of the rotating shaft 42. A drive assembly 47 is fixedly mounted on the frame 1, serving as the power source for the correction mechanism 4 and driving the movement of the entire linkage transmission device. The drive assembly 47 includes a fixing block 471 bolted to the frame 1 and a slide rail 473 fixedly arranged parallel to the frame 1. The slide rail 473 has a linearly extending groove 475 inside, within which a slider 474 slidably engages, allowing the slider 474 to perform smooth linear reciprocating motion guided by the groove 475.

[0038] A connecting block 46 is fixedly connected to the top of the slider 474. The connecting block 46 is elongated and horizontally arranged, with both ends extending to positions near the mounting plates 41 on both sides. A hydraulic cylinder 472 is connected between the fixed block 471 and the connecting block 46. The cylinder body end of the hydraulic cylinder 472 is connected to the fixed block 471, and the telescopic end is fixedly connected to the middle of the connecting block 46. When the hydraulic cylinder 472 is activated, the telescopic movement of its telescopic shaft directly pushes the connecting block 46, causing the slider 474 to move linearly along the slide rail 473. The design of dual hydraulic cylinders 472 or center drive helps to avoid uneven force during movement and ensures smooth execution of corrective actions.

[0039] Connecting blocks 44 are rotatably connected to both ends of the connecting block 46. One end of a connecting rod 45 is rotatably connected to each connecting block 44, and the other end of the connecting rod 45 extends to the inside of the mounting plate 41 and is rotatably connected to the mounting block 43 fixed on the mounting plate 41. The mounting block 43 is located on the side of the mounting plate 41 closer to the rotation shaft 42, thus forming a lever arm. When the connecting block 46 slides along the slide rail 473, the connecting rod 45 is pulled or pushed by the connecting block 44, and the connecting rod 45 in turn pushes and pulls the mounting block 43, driving the mounting plate 41 to deflect around the rotation shaft 42.

[0040] A correction block 48 is fixedly connected to the end of the mounting plate 41 away from the rotating shaft 42. The correction block 48 moves towards or away from the center of the conveyor belt 2 as the mounting plate 41 swings. A correction plate 411 is provided on the side of the correction block 48 facing the center of the conveyor belt 2. The correction plate 411 is the component that directly contacts the chip board 32 and performs the correction action. To prevent rigid contact from damaging the fragile chip board 32, a buffer structure is designed between the correction block 48 and the correction plate 411. Specifically, a number of spring posts 49 are connected between the two, and springs 410 are sleeved on the outer periphery of the spring posts 49. The two ends of the springs 410 abut against the side wall of the correction block 48 and the side wall of the correction plate 411, respectively.

[0041] When the correction mechanism 4 is working, the hydraulic cylinder 472 retracts, causing the connecting block 46 to slide, and through the linkage transmission, the mounting plates 41 on both sides swing inward synchronously. At this time, the correction plate 411 contacts the side of the chip board 32 that has shifted. During the process of pushing the chip board 32 back to its original position, the correction plate 411 is subjected to a reaction force that compresses the spring post 49 and the spring 410. The spring 410 is compressed to generate a buffering force, making the correction process smooth. This ensures that the chip board 32 is pushed to the preset processing and conveying position, and effectively avoids workpiece damage caused by hard collisions, greatly reducing the process error rate.

[0042] In a preferred embodiment, the feeding mechanism 3 employs a multi-cylinder collaborative feeding structure. The feeding mechanism 3 includes two opposing limiting plates 31, forming a feeding channel between the two limiting plates 31 that matches the size of the chip board 32. A lifting cylinder 34 is vertically installed at the center directly below the feeding channel. The top of the telescopic shaft of the lifting cylinder 34 is equipped with a tray for receiving and pushing the bottommost chip board 32 upwards. Simultaneously, a telescopic cylinder 33 is horizontally installed on the outer wall of the limiting plates 31. The telescopic end of the telescopic cylinder 33 can extend into the feeding channel through an opening or notch in the side wall of the limiting plates 31.

[0043] When material separation is required, the telescopic cylinder 33 extends to support the penultimate layer of chip board 32, and the lifting cylinder 34 supports the bottom layer of chip board 32 to descend, thereby achieving precise separation of single chips and avoiding the situation where multiple chips fall together, ensuring the stability and reliability of the feeding process.

[0044] In a preferred embodiment, the bottom of the limiting plate 31 is connected to an adjustment mechanism 5. The adjustment mechanism 5 includes a base plate 51 fixedly mounted on the top of the frame 1. The upper surface of the base plate 51 has multiple equally spaced limiting grooves 55 arranged linearly along the conveying direction perpendicular to the conveyor belt 2. These limiting grooves 55 not only serve a positioning function but also form an adjustment scale.

[0045] A connecting post 52 is fixedly installed at the bottom of the limiting plate 31. A blind hole with a downward-facing opening is opened inside the connecting post 52. A second spring 53 and a limiting bead 54 are sequentially installed inside the blind hole. The second spring 53 is in a compressed state, with one end abutting the bottom of the blind hole and the other end continuously pushing the limiting bead 54 downwards, causing a portion of the spherical surface of the limiting bead 54 to protrude from the bottom surface of the connecting post 52 in its natural state. When the operator needs to adjust the spacing of the limiting plates 31, a lateral thrust is applied to slide the limiting plates 31. The limiting bead 54 is compressed by the plane of the bottom plate 51 and retracts into the connecting post 52, compressing the second spring 53. When the limiting plate 31 moves to the predetermined position, the limiting bead 54 aligns with the lower limiting groove 55 and, under the elastic force of the second spring 53, quickly pops out and locks into the limiting groove 55, achieving automatic locking. This elastic ball-head locking structure not only facilitates adjustment but also effectively prevents accidental displacement of the limiting plate 31 during equipment operation vibration by utilizing the preload of the second spring 53.

[0046] In another preferred embodiment, a detection element 6 and a dust removal element 7 are sequentially arranged above the conveyor belt 2 and behind the unloading mechanism 3. The detection element 6 is installed across the conveyor belt 2 using a gantry-type structure, which can cover the detection field of the chip board 32 from above. The dust removal element 7 is installed immediately behind it on the side of the conveyor belt 2, which can promptly blow or vacuum the good chip boards 32 that have passed the inspection, remove micro-dust contamination from uncontrolled environments, and improve product yield.

[0047] The implementation principle of this application embodiment is as follows: The chip carrier tray automatic feeding mechanism consists of a frame 1, a conveyor belt 2 at the top of the frame 1, and a dropping mechanism 3 on the conveyor belt 2. The chip board 32 is dropped onto the conveyor belt 2 by the dropping mechanism 3. During the feeding process, the position can easily be offset. The correction mechanism 4 is used to correct this. An adjustment mechanism 5 is installed at the bottom of the limiting plate 31. The distance of the limiting plate 31 is adjusted by the adjustment mechanism 5. The chip board 32 is detected by the detection element 6 on the conveyor belt 2. When the detection is successful, the dust is removed by the dust removal element 7 on the frame 1. The control element 8 is installed on the rear side of the frame 1.

[0048] The chip carrier tray automatic feeding mechanism feeds the chip through the unloading mechanism 3. The chip board 32 is installed in the limiting plate 31. The lifting cylinder 34 is responsible for pushing the chip board 32 out of the limiting plate 31 and pushing the product to the discharge position. The telescopic cylinder 33 extends to support the chip board 32 and assists the lifting cylinder 34. The cylinder descends, and the bottom product can fall smoothly onto the conveyor belt 2. The chip board 32 enters the next process and falls onto the conveyor belt 2. This causes the chip board 32 to easily shift position during the feeding process, and the chip board 32 needs to be corrected.

[0049] A correction mechanism 4 is installed between the top of the frame 1 and the bottom of the conveyor belt 2. A mounting plate 41 is installed on the frame 1. The correction mechanism 4 is driven by a drive assembly 47. A hydraulic cylinder 472 connects the fixed block 471 and the connecting block 46. Driving the hydraulic cylinder 472 causes its hydraulic shaft to retract, causing the connecting block 46 to slide along the slider 474 within the groove 475 of the slide rail 473. This prevents uneven force distribution and ensures smooth execution of the correction action. Both ends of the connecting block 46 have hydraulic cylinders 472, allowing them to simultaneously drive the connecting block 46 to slide. The mounting plate 41 and rotating shaft 42 then rotate, causing the connecting block 46 to rotate as it slides. The connecting rod 45 is rotatably connected to the connecting block 44 and the mounting block 43. The movement of the connecting rod 45 drives the mounting block 43 to rotate through the rotating shaft 42, so that the correction block 48 on the connecting block 46 corrects the chip board 32, ensuring that the chip board 32 is in the preset processing and conveying position, providing reliable guarantee for the next process, and reducing the process error rate caused by positioning deviation. The correction block 48 is connected to the correction plate 411 through the spring post 49. The correction plate 411 contacts the chip board 32, so that the correction plate 411 squeezes the spring post 49. The spring 410 is sleeved on the spring post 49. The correction plate 411 squeezes the spring 410 synchronously, so that the correction plate 411 buffers the correction of the chip board 32 and prevents damage to the chip board 32.

[0050] When the chip board 32 is calibrated, it is tested by the detection element 6. If the chip board 32 is not tested well, it is ejected by the ejection element. If the chip board 32 is good, it proceeds to the next process. The chip board 32 is cleaned by the dust removal element 7. When the dust removal is good, the chip board 32 proceeds to the next process by the unloading and transfer element.

[0051] When the limiting plate 31 of the automatic feeding mechanism for the chip carrier tray cannot limit the chip boards 32 of different specifications, the width of the limiting plate 31 is adjusted by the adjusting mechanism 5. A connecting column 52 is installed at the bottom of the limiting plate 31, and the limiting plate 31 is installed on the base plate 51. The connecting column 52 contains a second spring 53 and a limiting bead 54. By sliding the limiting plate 31, the limiting bead 54 in the connecting column 52 is squeezed by the base plate 51, and the limiting bead 54 squeezes the second spring 53 to shrink. The second spring 53 in the connecting column 52 effectively prevents the limiting plate 31 from displacing due to external forces such as vibration of the conveyor belt 2 during the feeding process. When the limiting plate 31 is adjusted, multiple limiting grooves 55 are opened on the base plate 51. The pressure is released by the second spring 53 to fix the limiting bead 54 and the limiting grooves 55 opened on the base plate 51, preventing the limiting plate 31 from displacing.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
