Description
Technical Field
[0001] This invention relates to the field of chip delivery technology, and more particularly to a chip delivery device. Background Technology
[0002] During the chip manufacturing process, the solder balls and mirror surfaces of the chip need to be visually inspected to ensure product quality.
[0003] In existing technologies, chip conveying devices are equipment that transport chips to corresponding workstations to enable double-sided chip inspection. However, traditional chip conveying devices mostly use linear conveyor lines, which leads to the following shortcomings: Firstly, empty carriers that have completed inspection must return to the loading station via an independent return channel (such as a lower-level conveyor line, a hoist, and a circular line), which significantly increases the overall length, floor space, and mechanical complexity of the equipment. Secondly, the travel time of the carriers on the long return path becomes a potential factor affecting the overall cycle time. At the same time, the movement of a large number of carriers on the line also increases the risk of malfunctions such as jamming and collisions, affecting the overall efficiency of the equipment.
[0004] Therefore, existing chip delivery devices suffer from long return paths and low operating efficiency. Summary of the Invention
[0005] The purpose of this invention is to provide a chip delivery device that solves the problems of long return paths and low operating efficiency in existing chip delivery devices.
[0006] To achieve this objective, the present invention adopts the following technical solution: A chip delivery device includes a delivery component and a loading component. The delivery component includes a delivery frame on which a loop slide rail is mounted. The loop slide rail includes two linear slide rails and two arc-shaped slide rails. The track length of the linear slide rails is at least three times the track length of the arc-shaped slide rails, so that the running time of the loading component on the linear slide rails meets the preset stabilization time required for double-sided visual inspection of the chip. One of the arc-shaped slide rails is provided with a material detection sensor and a feeding station on one side, and a waiting station is provided on one side of the other arc-shaped slide rail. One of the linear slide rails is provided with a first detection station and a material turning station side by side on one side, and a second detection station and a material unloading station located between the second detection station and the feeding station are provided on one side of the other linear slide rail. The conveying component is used to drive the material carrier component to circulate on the loop slide rail according to a preset rhythm, and the time taken to move from the previous station to the next adjacent station is constant, so as to realize the double-sided visual inspection of the chip.
[0007] Optionally, one side of one of the linear slide rails is also provided with a cleaning station for cleaning the chip after it has been flipped. The cleaning station, the flipping station and the first detection station are arranged side by side in sequence, and the cleaning station is located between the flipping station and the second detection station. Another linear slide rail has a replenishment station on one side, which is used to remove the defective chips detected and replenish the defective chips with good chips; the second detection station, the replenishment station and the unloading station are arranged side by side in sequence.
[0008] Optionally, the material loading assembly has a positioning rod located outside the loop slide rail, and seven positioning cylinders are installed on one side of the conveyor frame. The seven positioning cylinders correspond one-to-one with the loading station, the first detection station, the turning station, the cleaning station, the second detection station, the replenishing station, and the unloading station. A positioning block is fixedly installed on the telescopic rod of the positioning cylinder. The positioning block is provided with a U-shaped positioning groove. The material loading assembly is positioned at the corresponding work station by the insertion and cooperation of the positioning rod with the positioning groove.
[0009] Optionally, the material loading assembly includes a material loading platform slidably connected to a loop slide rail, a first carrier plate and a second carrier plate are fixedly mounted on the material loading platform, a carrier tray carrying multiple chips is pressed onto the first carrier plate, and an empty and inverted carrier tray is embedded in the second carrier plate. The loading platform is equipped with a locking component for positioning and locking the trays on the first loading plate. The locking component is used to be locked during chip transport and unlocked during chip flipping. By flipping the two trays on the loading platform by 180 degrees at the flipping station, the chip in one of the trays falls into the empty tray.
[0010] Optionally, the locking assembly includes a locking disc, a locking member, and a locking spring. The locking disc is rotatably connected to the material carrier platform. One end of the locking member is slidably connected to the material carrier platform, and the other end of the locking member extends out of the first carrier plate and presses against the carrier disc. The two ends of the locking spring are connected to the locking disc and the material carrier respectively, and the two oppositely arranged locking springs are used to provide locking clamping force to the locking component.
[0011] Optionally, the locking disc is provided with an arc-shaped movable groove, the locking member is rotatably connected to a movable wheel that abuts against the movable groove, and the bottom of the locking disc is fixedly connected to an unlocking rod, which is used to cause the locking disc to slide along the direction away from the clamped carrier disc under the action of external thrust.
[0012] Optionally, the locking component includes a first locking block and a second locking block connected to each other. The first locking block is arranged in an inverted L shape and is slidably connected to the material carrier. The moving wheel is rotatably connected to the first locking block. The first carrier plate has a through hole, and the second locking block has an L-shaped locking part that passes through the through hole. The locking part clamps and engages with the carrier plate on the first carrier plate.
[0013] Optionally, the bottom of the loading platform is provided with two sliders located on the inner and outer sides of the spiral slide rail, and the bottom of the loading platform is rotatably connected with a pulley arranged adjacent to the sliders; Each slider has a heat dissipation hole for dissipating heat from the material carrier platform. One end of the heat dissipation hole faces the inner or outer side wall of the spiral slide rail, and the other end of the heat dissipation hole passes through the side of the slider that is away from the spiral slide rail.
[0014] Optionally, the conveying assembly further includes a rotating component located inside the loop slide rail and two oppositely arranged conveying wheels, one of which is rotatably connected to the conveyor frame and the other of which is connected to the rotating component; A conveyor belt is wound around the two conveyor wheels. The rotating component is used to drive the conveyor wheels to rotate according to a preset rhythm, so that the conveyor belt pulls the material loading assembly to circulate on the loop slide rail.
[0015] Optionally, the circumference of the conveyor belt is smaller than the circumference of the loop slide rail, the outer diameters of the two conveyor wheels are the same, the height of the rotating component is lower than the height of the conveyor wheels, and the rotating component is a rotary motor or a rotary cylinder. The conveyor belt is fixedly connected to the connecting block of the material loading assembly via a connecting flexible plate. Each conveyor wheel has a circular groove for avoiding the connecting flexible plate.
[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a chip delivery device that integrates multiple workstations on the side of a closed loop slide rail. The material carrier can circulate within the same loop, significantly reducing the overall length and floor space of the equipment, as well as lowering the complexity of the mechanical structure and manufacturing costs. Since the linear slide rail is at least three times the length of the arc slide rail, it ensures that the material carrier has a sufficiently long and stable running distance and time on the straight sections corresponding to the critical first and second inspection workstations, thereby meeting the preset stabilization time required for double-sided chip visual inspection and guaranteeing image quality. Because the carrier circulates within a single, compact loop track, it reduces the risks of carrier accumulation, mutual interference, jamming, and collisions caused by long distances and multiple loops. The constant movement time between all workstations facilitates precise synchronization and control, thereby improving the stability and reliability of equipment operation, reducing the failure rate, and contributing to continuous production and overall equipment efficiency. Therefore, this invention solves the problems of long loop paths and low operating efficiency in existing chip delivery devices. Attached Figure Description

[0021] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0022] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.
[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0024] This invention provides a chip delivery device, such as... Figures 1 to 8 As shown, the assembly includes a conveying component 10 and a loading component 20. The conveying component 10 includes a conveyor frame 11, on which a spiral slide rail 12 is mounted. The spiral slide rail 12 includes two linear slide rails 121 and two arc slide rails 122. The track length of the linear slide rail 121 is at least three times the track length of the arc slide rail 122, so that the running time of the loading component 20 on the linear slide rail 121 meets the preset stabilization time required for the double-sided visual inspection of the chip 200. One side of one of the arc-shaped slide rails 122 is provided with a material detection sensor 13 and a feeding station 41. The other side of the arc-shaped slide rail 122 is provided with a waiting station 45. One side of one of the linear slide rails 121 is provided with a first detection station 42 and a material turning station 43 side by side. The other side of the linear slide rail 121 is provided with a second detection station 46 and a material unloading station 48 located between the second detection station 46 and the feeding station 41. The conveying component 10 is used to drive the material carrier component 20 to circulate on the loop slide rail 12 according to a preset rhythm, and the time taken to move from the previous station to the next adjacent station is constant, so as to realize the double-sided visual inspection of the chip 200.
[0025] It should be noted that the chip conveying device provided by this invention integrates multiple workstations on the side of a closed loop slide rail 12, allowing the material carrier 20 to circulate within the same loop. This significantly reduces the overall length and floor space of the equipment, as well as the complexity of the mechanical structure and manufacturing costs. Since the track length of the linear slide rail 121 is at least three times that of the arc-shaped slide rail 122, it ensures that the material carrier 20 has a sufficiently long and stable running distance and time on the straight sections corresponding to the critical first detection workstation 42 and the second detection workstation 46, thereby meeting the preset stable time required for double-sided visual inspection of the chip 200 and guaranteeing imaging quality. Because the carrier circulates within a single, compact loop track, the risks of carrier accumulation, mutual interference, jamming, and collisions caused by long distances and multiple loops are reduced. The constant movement time between all workstations facilitates precise synchronization and control, thereby improving the stability and reliability of equipment operation, reducing the failure rate, and contributing to continuous production and overall equipment efficiency. Therefore, this invention solves the problems of long loop paths and low operating efficiency in existing chip conveying devices.
[0026] like Figure 1 As shown, one side of one of the linear slide rails 121 is also provided with a cleaning station 44 for cleaning the chip 200 after it has been flipped. The cleaning station 44, the flipping station 43 and the first inspection station 42 are arranged side by side in sequence, and the cleaning station 44 is located between the flipping station 43 and the second inspection station 46. Another linear slide rail 121 has a replenishment station 47 on one side. The replenishment station 47 is used to remove the defective chip 200 and replenish the good chip 200 to the position of the defective chip 200. The second detection station 46, the replenishment station 47 and the unloading station 48 are arranged side by side in sequence.
[0027] In practical implementation, by directly setting up a cleaning station 44 on the conveying path, particles or stains adhering to the chip 200 during the flipping operation can be removed online. This ensures the cleanliness of the second side of the chip 200 during inspection, effectively avoiding misjudgments caused by contamination, thereby significantly improving the accuracy and reliability of double-sided visual inspection of the chip 200. Simultaneously, integrating the replenishment station 47 after the second inspection station 46 and before the unloading station 48 enables online, real-time, and continuous operation from detection and rejection to replenishment. The system can complete rejection and replenishment of good products within the same cycle the instant defective products are detected, ensuring that each carrier exits with a full load of good products. This not only improves the quality consistency of the final chip 200 output but also provides directly usable qualified semi-finished products for subsequent processes.
[0028] like Figures 1 to 7As shown, the material loading assembly 20 has a positioning rod 22 located on the outside of the loop slide rail 12. Seven positioning cylinders 17 are installed on one side of the conveyor frame 11. The seven positioning cylinders 17 correspond one-to-one with the loading station 41, the first inspection station 42, the turning station 43, the cleaning station 44, the second inspection station 46, the replenishing station 47, and the unloading station 48. A positioning block 18 is fixedly installed on the telescopic rod of the positioning cylinder 17. The positioning block 18 is provided with a U-shaped positioning groove 181. The material loading assembly 20 is positioned at the corresponding work station by the insertion and cooperation of the positioning rod 22 with the positioning groove 181.
[0029] In practice, the positioning block 18 with a U-shaped positioning groove 181 is moved by the positioning cylinder 17, so that the positioning block 18 can be inserted and engaged with the positioning rod 22 on the outside of the material carrier 20, realizing the mechanical hard positioning of the material carrier 20 at each key operation station. This forced physical locking can instantly eliminate the slight shaking or positional deviation of the carrier after the conveying stops, ensuring that the chip 200 has high repeatability and static stability in its spatial position during processes such as visual inspection, flipping, and cleaning.
[0030] like Figures 2 to 4 As shown, the material loading assembly 20 includes a material loading platform 21 slidably connected to the loop slide rail 12. A first carrier plate 23 and a second carrier plate 24 are fixedly mounted on the material loading platform 21. A carrier plate 100 carrying multiple chips 200 is pressed onto the first carrier plate 23. An empty and inverted carrier plate 100 is embedded in the second carrier plate 24. The loading platform 21 is equipped with a locking assembly 30 for positioning and locking the tray 100 on the first loading plate 23. The locking assembly 30 is used to lock the chip 200 during its conveying movement and to unlock it during the chip 200 flipping operation. By flipping the two trays 100 on the loading platform 21 by 180 degrees at the flipping station 43, the chip 200 in one of the trays 100 falls into the empty tray 100. In this embodiment, the tray 100 is provided with a placement slot 101 for placing the chip 200, and the four sides of the tray 100 are provided with clamping slots 102 for easy gripping by an external robotic arm. The first loading plate 23 is provided with a notch 232, which facilitates the external flipping structure to clamp the tray 100. The second loading plate 24 is provided with a stepped groove 241 for insertion and engagement with the inverted tray 100. With the step groove 241 in place, the inverted tray 100 will not shift or fall off when the material loading assembly 20 moves on the loop slide rail 12.
[0031] In practical implementation, a first carrier plate 23 (carrying the chip to be inspected 200) and a second carrier plate 24 (embedded with an inverted empty tray 100) are integrated on the loading platform 21. An external mechanism at the flipping station 43 flips the two trays 100 180 degrees, allowing the chip 200 to automatically and smoothly fall into the previously empty tray 100 under gravity, instantly completing the flipping of the entire tray of chips 200. A locking component 30 is provided within the loading platform 21, its working logic and process perfectly coordinated: it automatically locks during chip 200 transport, firmly fixing the tray 100 carrying the chip 200 to the first carrier plate 23, effectively preventing any slippage or vibration of the tray 100 during high-speed start-stop and arc-shaped turns; the locking component 30 only switches to the unlocked state when reaching the flipping station 43, providing operating space for the external flipping mechanism.
[0032] like Figures 2 to 6 As shown, the locking assembly 30 includes a locking disc 31, a locking member 32, and a locking spring 33. The locking disc 31 is rotatably connected to the material carrier 21. One end of the locking member 32 is slidably connected to the material carrier 21, and the other end of the locking member 32 passes through the first carrier plate 23 and is pressed against the carrier disc 100. The two ends of the locking spring 33 are connected to the locking disc 31 and the loading platform 21, respectively. The two oppositely arranged locking springs 33 are used to provide locking clamping force to the locking member 32. In this embodiment, locking screws are fixedly connected to both the locking disc 31 and the loading platform 21, and the ends of the locking springs 33 are fixedly connected to the locking screws. The locking springs 33 are arranged in an inclined state. For example, the number of locking members 32 can be two or four, and the number of locking springs 33 is two.
[0033] In practical implementation, by employing two oppositely arranged and inclined locking springs 33 as the core force-applying elements, this design provides a continuous, stable, and directionally optimized clamping preload for the locking element 32. The inclined locking springs 33 effectively convert their force into an axial pressing force on the locking element 32, thereby ensuring that the other end of the locking element 32 firmly presses the carrier plate 100 onto the first carrier plate 23. This purely mechanical locking method maintains the locking state without relying on external power. Even in the event of a sudden power outage or air supply failure, the carrier plate 100 can still be reliably fixed, preventing the risk of displacement or loosening of the carrier plate 100 due to vibration or inertia during transport, thus ensuring the safety of the chip 200. By overcoming the clamping force of the locking springs 33, the locking disc 31 is driven to rotate, causing the locking element 32 to move away from the carrier plate 100 on the first carrier plate 23, thereby achieving rapid and consistent unlocking.
[0034] like Figures 3 to 6As shown, the locking disc 31 has an arc-shaped moving groove 311 inside, and the locking member 32 is rotatably connected to a moving wheel 34 that abuts against the moving groove 311. The bottom of the locking disc 31 is fixedly connected to an unlocking rod 35, which is used to make the locking disc 31 drive the locking member 32 to slide in a direction away from the clamping carrier disc 100 under the action of external thrust.
[0035] In specific implementation, an arc-shaped movable groove 311 is provided within the locking disc 31, which cooperates with the movable wheel 34 on the locking member 32 to convert the rotational motion of the locking disc 31 into the precise linear reciprocating motion of the locking member 32. This wheel-groove cooperation greatly reduces frictional resistance and wear during the motion conversion process, making the unlocking and locking actions smoother and less strenuous. Simultaneously, the trajectory constraint of the movable groove 311 on the movable wheel 34 ensures the precision and consistency of the locking member 32's movement path, avoiding potential jamming or deflection, thereby significantly improving the reliability and repeatability of the locking state switching. The unlocking lever 35, as an extended mechanical interface, provides a clear and direct point of application for the external unlocking mechanism. The external unlocking mechanism only needs to apply a simple linear thrust to the unlocking lever 35 to efficiently drive the locking disc 31 to rotate through the lever principle, moving the locking member 32 away from the carrier plate 100 on the first carrier plate 23, thus completing the unlocking action. Conversely, when the external unlocking mechanism's thrust disappears, the locking disc 31 rotates in the opposite direction under the elastic force of the locking spring 33, causing the locking member 32 to move linearly, so that the locking member 32 clamps and fixes the carrier disc 100 on the first carrier plate 23.
[0036] like Figure 5 and Figure 6 As shown, the locking member 32 includes a first locking block 321 and a second locking block 322 connected to each other. The first locking block 321 is arranged in an inverted L shape and is slidably connected to the material platform 21. The moving wheel 34 is rotatably connected to the first locking block 321. The first carrier plate 23 has a through hole 231, and the second locking block 322 has an L-shaped locking part 3221 that passes through the through hole 231. The locking part 3221 is clamped and engaged with the carrier plate 100 on the first carrier plate 23.
[0037] In practical implementation, since the locking part 3221 of the second locking block 322 passes through the perforation 231 on the first carrier plate 23 and acts directly on the four corners of the carrier plate 100, the carrier plate 100 is clamped, effectively avoiding the risk of slight twisting or tilting of the carrier plate 100 in the locked state. Combined with the support of the first carrier plate 23 itself, a reliable clamping of the carrier plate 100 is formed. The perforation 231 is designed to provide precise guidance and avoidance for the movement of the locking part 3221, preventing motion interference between the locking part 3221 and the first carrier plate 23.
[0038] like Figure 2 and Figure 3 As shown, the bottom of the loading platform 21 is provided with two sliders 26 located on the inner and outer sides of the spiral slide rail 12, and the bottom of the loading platform 21 is rotatably connected with a pulley 27 arranged adjacent to the sliders 26. Each slider 26 has a heat dissipation hole 261 for cooling the loading platform 21. One end of the heat dissipation hole 261 is gapped towards the inner or outer side wall of the loop slide rail 12, and the other end of the heat dissipation hole 261 extends through the side of the slider 26 facing away from the loop slide rail 12. It is worth mentioning that the heat dissipation hole 261 includes a first hole segment 2611 and a second hole segment 2612 that extend through in sequence. The first hole segment 2611 is close to the loop slide rail 12, and the cross-sectional area of the first hole segment 2611 is larger than the cross-sectional area of the second hole segment 2612.
[0039] In practical implementation, during the high-frequency cyclic movement of the material carrier assembly 20 along the loop slide rail 12, the continuous friction between the slider 26 and the rail is the main heat source. By opening heat dissipation holes 261 on the slider 26, with one end of the holes facing the inner or outer wall of the rail, the relative movement between the slider 26 and the rail wall naturally compresses the air as the platform 21 moves. This forces the airflow through the heat dissipation holes 261, creating a directional "piston effect" or "pumped airflow." This forced convection cooling, driven by its own kinetic energy, efficiently removes frictional heat from the contact area of the slider 26 without the need for any external fan or cooling system. This significantly reduces the operating temperature of the slider 26 and even the entire platform 21, effectively preventing lubricant failure, material softening and accelerated wear, or localized thermal deformation due to overheating, thus ensuring positioning accuracy and mechanical stability during long-term operation.
[0040] Furthermore, the heat dissipation hole 261 adopts a variable cross-section design of "large inlet and small outlet" (the cross-sectional area of the first hole section 2611 is larger than that of the second hole section 2612), which produces multiple synergistic effects: First, the first hole section 2611, which is closer to the loop slide rail 12 and has a larger cross-sectional area, can more effectively "capture" and guide the airflow generated by relative motion into the hole, thereby increasing the airflow rate; Second, when the airflow enters the narrower second hole section 2612 from the larger cross-sectional area of the first hole section 2611, the flow velocity increases; according to the principle of fluid dynamics, the increase in flow velocity can enhance the convective heat transfer coefficient between the airflow and the hole wall, thereby transferring the heat of the metal material of the slider 26 to the air more quickly and carrying it away; Third, the second hole section 2612 extends to the side of the slider 26 facing away from the loop slide rail 12, guiding the heated airflow to a relatively open and low-pressure area inside the equipment for smooth discharge, avoiding the accumulation of hot air near the loop slide rail 12, and forming an effective closed-loop airflow of "inhaling cold air → flowing through the heat source to accelerate heat exchange → discharging hot air".
[0041] like Figure 1 and Figure 8As shown, the conveying assembly 10 also includes a rotating component 14 located inside the loop slide rail 12 and two oppositely arranged conveying wheels 15, one of which is rotatably connected to the conveyor frame 11 and the other is connected to the rotating component 14. Two conveyor wheels 15 are wound with conveyor belts 16. A rotating component 14 drives the conveyor wheels 15 to rotate according to a preset rhythm, so that the conveyor belts 16 pull the material loading assembly 20 to circulate on the loop slide rail 12. In this embodiment, the conveyor wheels 15 and the conveyor belts 16 are connected by toothed meshing.
[0042] In practical implementation, the rotating component 14 located inside the loop slide rail 12 drives the conveyor wheel 15 to rotate, and the rotation is transmitted to the conveyor belt 16 through a toothed meshing connection, thus constructing a rigid synchronous drive system. This design eliminates the slippage phenomenon of belt drive, ensuring that the drive displacement is accurately transmitted to the material loading assembly 20. This allows the material loading assembly 20 to move between workstations on the loop slide rail 12 strictly according to the preset rhythm, achieving a constant duration of stepping motion, laying a solid foundation for a stable and predictable production rhythm for the entire system. Integrating the drive source (rotating component 14) and the main transmission component (conveyor wheel 15) inside the loop slide rail 12 makes full use of the internal space of the rail and avoids the expansion of the overall equipment layout caused by external drive mechanisms. This embedded design further enhances the compactness of the equipment structure and reduces the floor space.
[0043] like Figures 1 to 8 As shown, the circumference of the conveyor belt 16 is smaller than the circumference of the loop slide rail 12, the outer diameters of the two conveyor wheels 15 are the same, the height of the rotating component 14 is lower than the height of the conveyor wheels 15, and the rotating component 14 is a rotary motor or a rotary cylinder. The conveyor belt 16 is fixedly connected to the connecting block 25 of the material loading assembly 20 via a connecting flexible plate (not shown). Each conveyor wheel 15 has a ring-shaped clearance groove 151 for avoiding obstruction of the connecting flexible plate. In this embodiment, the conveyor wheel 15 has two rings of teeth, and the clearance groove 151 is located between the two rings of teeth. The connecting block 25 is fastened to the material loading platform 21 with screws.
[0044] In practical implementation, since the circumference of the conveyor belt 16 is smaller than that of the loop slide rail 12, and it is connected to the connecting block 25 of the material loading assembly 20 with the connecting flexible plate (not shown), a "short belt driving long stroke" traction mode is creatively realized. This design allows the rotating component 14, the conveyor wheel 15, and the conveyor belt 16 to be arranged in the limited space inside the track without matching the full length of the track, which greatly reduces the size and space occupied by the above components, making the entire drive unit more compact. By designing the height of the rotating component 14 to be lower than that of the conveyor wheel 15, the vertical space utilization is further optimized, making the overall structure more flat. As a flexible connector, the connecting flexible plate effectively absorbs the assembly stress caused by the change in path curvature between the fixed point of the conveyor belt 16 and the material loading assembly 20, and prevents motion interference, ensuring the smooth transmission of traction force. By opening an annular clearance groove 151 on each conveyor wheel 15 and precisely setting the clearance groove 151 between two rings of teeth, a dedicated physical clearance space is provided for the connecting flexible plate as it passes around the conveyor wheel 15 with the conveyor belt 16. This design avoids squeezing, scraping, or interference between the connecting flexible plate and the teeth of the conveyor wheel 15, ensuring the integrity and reliability of the tooth meshing transmission, thereby guaranteeing the stability and lifespan of the conveying assembly 10 during long-term high-speed cyclic operation.
[0045] Working Principle: The chip conveying device provided by this invention integrates multiple workstations on the side of a closed loop slide rail 12, allowing the material carrier assembly 20 to circulate within the same loop. This significantly reduces the overall length and floor space of the equipment, as well as the complexity of the mechanical structure and manufacturing costs. Since the track length of the linear slide rail 121 is at least three times that of the arc-shaped slide rail 122, it ensures that the material carrier assembly 20 has a sufficiently long and stable running distance and time on the straight sections corresponding to the critical first detection workstation 42 and the second detection workstation 46. This meets the preset stable time required for double-sided visual inspection of the chip 200, ensuring imaging quality. Because the carrier circulates within a single, compact loop track, it reduces the risks of carrier accumulation, mutual interference, jamming, and collisions caused by long distances and multiple loops. The constant movement time between all workstations facilitates precise synchronization and control, thereby improving the stability and reliability of the equipment operation, reducing the failure rate, and contributing to continuous production and overall equipment efficiency. Therefore, this invention solves the problems of long loop paths and low operating efficiency in existing chip conveying devices.
