Description

Technical Field

[0001] This utility model relates to the field of chip processing technology, specifically to a memory chip positioning and detection device. Background Technology

[0002] With the rapid development of electronic information technology, memory chips, as core components of various electronic devices, face increasingly stringent quality requirements in their production. In the modern semiconductor manufacturing field, precise chip positioning and rapid testing have become crucial links in the production process, directly affecting product yield and production efficiency.

[0003] According to CN218370419U, a chip detection and handling device and chip detection equipment are disclosed. This technology discloses a technical solution that includes: "at least two handling modules, a first linear motion module driving the handling module to rise and fall, the handling module including a handling cylinder, a rotary drive source, a suction nozzle and a rotating shaft, the working end of the handling cylinder connected to the rotary drive source, the output end of the rotary drive source connected to the rotating shaft, the rotating shaft connected to the suction nozzle, and the suction nozzle picking up the chip; a chip detection posture module, a second linear motion module driving the detection posture module to rise and fall, the chip detection posture module including a light source, a camera adjustment base and a camera, the camera mounted on the camera adjustment base, the camera adjustment base being located on a second guide module; wherein, the light source, the first linear motion module and the second linear motion module are all mounted on the same fixed plate." This technical solution has the technical effect of "effectively combining the relatively independent chip handling and handling device and the posture detection device to improve detection efficiency."

[0004] The above solution has difficulty in reliably clamping and stabilizing chip trays of different sizes during continuous feeding. The trays are prone to shaking or changes in position during lifting or movement, which directly leads to the failure of the pick-and-place components to pick up chips or inaccurate positioning, as well as blurry images or positioning deviations in the vision inspection system, which in turn causes a series of problems such as missed detections, false detections, or even chip damage. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a memory chip positioning and detection device. Through an adaptive clamping mechanism and automatic lifting, it achieves precise positioning and continuous feeding of chip trays of different specifications, ensuring the stability and efficiency of the detection process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a memory chip positioning and detection device, comprising a processing table, wherein a processing mechanism is provided on the processing table for chip feeding, and the processing mechanism includes:

[0007] The lifting assembly includes a base located on the left side of the machining table;

[0008] The feeding assembly includes two base plates fixed at the top of the machine base and fixed back-to-back. Four circumferentially arranged guide rails are fixed on the top of the base plates. Sliders are slidably mounted on the guide rails. A circular block is fixed on the upper end of the slider. A limit frame is fixed on the upper end of the circular block. A disc is rotatably mounted on the upper end of the base plates. A servo motor is mounted on the bottom of the base plates to drive the disc to rotate. Four circumferentially arranged arc grooves are opened inside the disc, and the circular block is located inside the arc grooves. A cross bracket is set above the disc. Uprights are fixed at both ends of the top of the base plates and are slidably mounted on the cross brackets. Rollers are installed at the four corners of the bottom of the base plates.

[0009] A pick-and-place component is mounted on the feeding component and used for picking up and placing chips.

[0010] The inspection component is set on the processing table and used for chip visual inspection.

[0011] Preferably, the lifting assembly includes wheel rails fixed to the left and right ends of the top of the base and cooperating with rollers, and a first cylinder is installed at the upper end of the base for driving the base plate to move.

[0012] Preferably, the lifting assembly further includes a vertical frame fixed to the left and right ends of the base, with a first sprocket rotatably mounted on both the upper and lower ends of the vertical frame, a first chain installed between the two first sprockets, and a bracket slidably mounted on the vertical frame, with the bracket fixed to the first chain.

[0013] Preferably, the lifting assembly further includes a shaft fixed between the first sprockets on both sides of the lower end, a second sprocket fixed in the middle of the outer wall of the shaft, a reduction motor installed at the bottom of the base, and a second chain installed between the output end of the reduction motor and the second sprocket through the sprocket.

[0014] Preferably, the pick-and-place assembly includes a column fixed on the base, a transverse slide fixed on the column, a second cylinder mounted on the transverse slide, and a suction cup mounted on the output end of the second cylinder.

[0015] Preferably, the detection component includes a body located at the center of the top of the processing table, an industrial camera mounted on the body, and a conveyor belt located on the left side of the top of the processing table.

[0016] Beneficial effects

[0017] This invention provides a memory chip positioning and detection device. Compared with the prior art, it has the following advantages:

[0018] 1. By stacking the chip-containing trays on the cross bracket, the servo motor at the bottom of the substrate drives the disk to rotate. The four arc-shaped grooves inside the disk form a precise sliding fit with the circular blocks fixed on the sliders, converting the rotational motion of the disk into the synchronous radial motion of the four sliders along the guide rail. The upper end of the slider is connected to the limit frame through the circular block, so that the four limit frames can achieve precise synchronous opening and closing action. By adjusting the rotation angle of the servo motor, the clamping stroke of the limit frame can be precisely controlled, thereby realizing adaptive centering clamping or loosening of trays of different specifications. In addition, the cross bracket maintains vertical guidance through the upright, ensuring that the tray always maintains a stable vertical posture during the clamping process, preventing tilting or displacement.

[0019] 2. When the geared motor starts, the sprocket at its output end begins to rotate. Connected to the second sprocket via a second chain, the second chain transmits the power of the geared motor to the second sprocket, which in turn drives the shaft to rotate. Since the shaft is fixed to the first sprockets on both sides of the lower end, its rotation drives the first sprockets to rotate. When the first sprocket at the lower end rotates, the first chain, installed between the two first sprockets, will circulate according to the chain drive principle. The bracket is longitudinally slidably mounted on the upright and fixedly connected to the first chain. This allows the first chain to drive the bracket to move longitudinally up or down along the upright during its movement. The bracket is also connected to the cross bracket in the feeding assembly; as the bracket rises and falls, it pushes the cross bracket to rise and fall together. This ensures a continuous supply of chips to the trays stacked on the cross brackets, guaranteeing the continuity and efficiency of the chip positioning and detection work.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a memory chip positioning and detection device, including a processing table 1, on which a processing mechanism 2 is provided for chip feeding, the processing mechanism 2 including:

[0028] The lifting assembly 21 includes a base 211 disposed on the left side of the processing table 1;

[0029] The feeding assembly 22 includes two base plates 221 disposed above the base 211 and fixed to each other front and back. Four circumferentially arranged guide rails 222 are fixed on the top of the base plates 221. A slider 223 is slidably mounted on the guide rails 222. A circular block 224 is fixed on the upper end of the slider 223. A limit frame 225 is fixed on the upper end of the circular block 224. A disc 226 is rotatably mounted on the upper end of the base plates 221. A servo motor is mounted on the bottom of the base plates 221 to drive the disc 226 to rotate. Four circumferentially arranged arc grooves 227 are opened inside the disc 226, and the circular block 224 is located inside the arc grooves 227. A cross bracket 228 is disposed above the disc 226. Uprights 229 are fixed at both ends of the top of the base plates 221 and are slidably mounted with the cross bracket 228. Rollers 2210 are mounted at the four corners of the bottom of the base plates 221.

[0030] The pick-and-place component 23 is disposed on the feeding component 22 and is used for chip pick-and-place;

[0031] The detection component 24 is set on the processing table 1 and is used for chip visual inspection.

[0032] In this embodiment, by stacking the chip-containing trays on the cross bracket 228, the servo motor at the bottom of the substrate 221 drives the disk 226 to rotate. The four arc-shaped grooves 227 inside the disk form a precise sliding fit with the circular blocks 224 fixed on the sliders 223, converting the rotational motion of the disk into the synchronous radial motion of the four sliders 223 along the guide rail 222. The upper end of the sliders 223 is connected to the limiting frame 225 through the circular blocks 224, so that the four limiting frames 225 can achieve precise synchronous opening and closing actions. By adjusting the rotation angle of the servo motor, the clamping stroke of the limiting frame 225 can be precisely controlled, thereby realizing adaptive centering clamping or loosening of trays of different specifications. In addition, the cross bracket 228 maintains vertical guidance through the upright 229, ensuring that the tray always maintains a stable vertical posture during the clamping process, preventing tilting or displacement.

[0033] Specifically, the lifting assembly 21 includes wheel rails 212 fixed at both ends of the top of the base 211 and cooperating with rollers 2210. A first cylinder 213 is installed on the upper end of the base 211 and is used to drive the base plate 221 to move.

[0034] In this embodiment, the first cylinder 213 drives the two feeding components 22 to move simultaneously. The rollers 2210 of the feeding components 22 cooperate with the wheel rails 212, enabling the feeding components 22 to move stably along a predetermined route in the horizontal direction, effectively avoiding deviation or jamming during the movement. Furthermore, since two feeding components 22 are provided, the feeding component 22 located between the two end supports 214 is used to normally supply the trays containing chips to the subsequent testing process, ensuring the continuous operation of the testing process. The other feeding component 22 serves as a replenishment unit, which can quickly replenish the chips supplied by the former when the quantity is insufficient or when it is necessary to replace the chips with chips of different specifications, ensuring that the testing work is not interrupted due to supply problems.

[0035] Specifically, the lifting assembly 21 also includes a frame 214 fixed to the left and right ends of the base 211. The upper and lower ends of the frame 214 are rotatably mounted with first sprockets 215. A first chain 216 is installed between the two first sprockets 215. A bracket 217 is longitudinally slidably mounted on the frame 214 and is fixed to the first chain 216.

[0036] In this embodiment, when the lower first sprocket 215 rotates, the first chain 216, which is installed between the two first sprockets 215, will circulate according to the principle of chain drive. The bracket 217 is longitudinally slidably installed on the upright 214 and is fixedly connected to the first chain 216. This allows the first chain 216 to drive the bracket 217 to move longitudinally up or down along the upright 214 during the movement. The bracket 217 is also connected to the cross bracket 228 in the feeding assembly 22. As the bracket 217 rises and falls, it can push the cross bracket 228 to rise and fall together. This ensures that the tray containing the chips stacked on the cross bracket 228 is continuously fed, guaranteeing the continuity and efficiency of the chip positioning and detection work.

[0037] Specifically, the lifting assembly 21 also includes a shaft 218 fixed between the first sprockets 215 on both sides of the lower end, a second sprocket 219 fixed in the middle of the outer wall of the shaft 218, a reduction motor 2110 installed at the bottom of the base 211, and a second chain 2111 installed between the output end of the reduction motor 2110 and the second sprocket 219 through the sprocket.

[0038] In this embodiment, when the geared motor 2110 starts, the sprocket at its output end begins to rotate. It is connected to the second sprocket 219 via the second chain 2111. According to the principle of chain drive, the second chain 2111 transmits the power of the geared motor 2110 to the second sprocket 219, thereby driving the shaft 218 to rotate. Since the shaft 218 is fixed to the first sprockets 215 on both sides of the lower end, the rotation of the shaft 218 will drive the first sprockets 215 to rotate.

[0039] Specifically, the pick-and-place assembly 23 includes a column 231 fixed on the base 211, a transverse slide 232 fixed on the column 231, a second cylinder 233 installed on the transverse slide 232, and a suction cup 234 installed at the output end of the second cylinder 233.

[0040] In this embodiment, the transverse slide 232 drives the second cylinder 233 mounted on it to move laterally to a suitable position. Then, the second cylinder 233 is activated, and its output end extends downward, pushing the suction cup 234 mounted on the output end closer to the chip. The suction cup 234 uses the principle of negative pressure to attract the chip. Afterward, the output end of the second cylinder 233 retracts, lifting the chip. Then, through the movement of the transverse slide 232, the tray containing the chip is accurately placed onto the conveyor belt 243.

[0041] Specifically, the detection component 24 includes a body 241 located at the top center of the processing table 1, an industrial camera 242 mounted on the body 241, and a conveyor belt 243 located on the top left side of the processing table 1.

[0042] In this embodiment, after the tray containing the chip is placed on the conveyor belt 243, it is transported to the area below the industrial camera 242. The industrial camera 242 can quickly and accurately capture the image information of the chip and transmit this information to the subsequent image processing system for analysis and judgment, thereby achieving precise positioning and quality inspection of the chip.

[0043] The working principle and usage process of this utility model are as follows: First, the first cylinder 213 drives the two feeding components 22 to move simultaneously. The rollers 2210 of the feeding components 22 cooperate with the wheel rails 212, enabling the feeding components 22 to move stably along a predetermined route in the horizontal direction, effectively avoiding deviation or jamming during the movement. Furthermore, since two feeding components 22 are set, the feeding component 22 located between the two end supports 214 is used to normally supply the trays containing chips to the subsequent testing process, ensuring the continuous operation of the testing process. The other feeding component 22 serves as a replenishment unit, which can quickly replenish the chips supplied by the former when the quantity is insufficient or when it is necessary to replace the chips with different specifications, ensuring that the testing work is not interrupted due to feeding problems.

[0044] Then, by stacking the chip-containing trays on the cross bracket 228, the servo motor at the bottom of the substrate 221 drives the disk 226 to rotate. The four arc-shaped grooves 227 inside the disk form a precise sliding fit with the circular blocks 224 fixed on the sliders 223, converting the rotational motion of the disk into the synchronous radial motion of the four sliders 223 along the guide rail 222. The upper end of the sliders 223 is connected to the limiting frame 225 through the circular blocks 224, so that the four limiting frames 225 can achieve precise synchronous opening and closing actions. By adjusting the rotation angle of the servo motor, the clamping stroke of the limiting frame 225 can be precisely controlled, thereby realizing adaptive centering clamping or loosening of trays of different specifications. In addition, the cross bracket 228 maintains vertical guidance through the upright 229, ensuring that the tray always maintains a stable vertical posture during the clamping process, preventing tilting or displacement.

[0045] Subsequently, when the geared motor 2110 starts, the sprocket at its output end begins to rotate. It is connected to the second sprocket 219 via the second chain 2111. Based on the principle of chain drive, the second chain 2111 transmits the power of the geared motor 2110 to the second sprocket 219, which in turn drives the shaft 218 to rotate. Since the shaft 218 is fixed to the first sprockets 215 on both lower ends, the rotation of the shaft 218 drives the first sprockets 215 to rotate. When the lower first sprockets 215 rotate, because a first chain 216 is installed between the two first sprockets 215, according to the principle of chain drive, the first chain... The first chain 216 will perform a cyclical movement, while the bracket 217 is longitudinally slidably mounted on the upright 214 and fixedly connected to the first chain 216. This allows the first chain 216 to drive the bracket 217 to move longitudinally up or down along the upright 214 during movement. The bracket 217 is also connected to the cross bracket 228 in the feeding assembly 22. As the bracket 217 rises and falls, it can push the cross bracket 228 to rise and fall together. This ensures that the tray containing the chips stacked on the cross bracket 228 is continuously fed, guaranteeing the continuity and efficiency of the chip positioning and detection work.

[0046] Finally, the horizontal slide 232 drives the second cylinder 233 mounted on it to move laterally to a suitable position. Then, the second cylinder 233 is activated, and its output end extends downward, pushing the suction cup 234 mounted on the output end closer to the chip. The suction cup 234 uses the principle of negative pressure to attract the chip. Then, the output end of the second cylinder 233 retracts, lifting the chip. Then, through the movement of the horizontal slide 232, the tray containing the chip is accurately placed onto the conveyor belt 243. After the tray containing the chip is placed on the conveyor belt 243, it is transported to the area below the industrial camera 242. The industrial camera 242 can quickly and accurately capture the image information of the chip and transmit this information to the subsequent image processing system for analysis and judgment, thereby achieving precise positioning and quality inspection of the chip.
