Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor appearance inspection equipment technology, and in particular to a fully automatic inspection and sorting system. Background Technology
[0002] After semiconductor chips are manufactured, their outer surface needs to be inspected to ensure they are qualified for shipment. For example, Chinese invention patent CN202410728157.X discloses a fully automatic appearance inspection system, including a first flow channel, a second flow channel, a third flow channel, an inspection mechanism, a first conveying device, and a second conveying device. The first flow channel is used to transport trays containing products to be inspected. The first conveying device is used to transport the products in the trays of the first flow channel to the inspection mechanism for inspection and to return the inspected products to the trays. The second and third flow channels can receive the inspected trays. The second conveying device is used to transport unqualified products from the trays of the third flow channel to the trays of the second flow channel and qualified products from the trays of the second flow channel to the trays of the third flow channel. Then, the second and third flow channels unload and stack the sorted trays.
[0003] In addition, the detection system includes a tape-and-reel device located in the third flow channel. When qualified products need to be tape-and-reeled, the tape-and-reel device can remove qualified products from the material tray in the third flow channel and then tape and rewind them. However, with the above structure, when tape-and-reeling is performed, the material trays stacked after unloading from the third flow channel are empty. Operators may easily mistake these empty trays for trays of qualified products when retrieving them later, causing abnormalities in subsequent processes. Furthermore, when the tape-and-reel device is handling products in the trays, subsequent trays are difficult to flow to the third flow channel. That is, during the operation of the tape-and-reel device, the second handling device is in standby mode, affecting work efficiency.
[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0061] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0062] Please see Figures 1 to 3 As shown, a fully automatic detection and sorting system corresponding to a preferred embodiment of this utility model includes: a flow channel device, including a first flow channel 110, a second flow channel 120, a third flow channel 130, and a fourth flow channel 140; the first flow channel 110 is used to convey a tray 150 containing products to be detected; the second flow channel 120 is used to load empty trays 150; the third flow channel 130 is used to receive trays 150 after detection by the first flow channel 110; and the fourth flow channel 140 is used to receive trays 150 after sorting by the third flow channel 130; a detection device for detecting the appearance of the products; and a handling and sorting device. 200 includes a first conveying mechanism 210 and a sorting mechanism 220. The first conveying mechanism 210 is used to convey products in the loading tray 150 of the first flow channel 110 to the testing device, and the sorting mechanism 220 is used to convey unqualified products in the loading tray 150 of the third flow channel 130 to the loading tray 150 of the second flow channel 120. A tape-making device 500 is adapted to remove products from the loading tray 150 of the fourth flow channel 140 and tape them. A transfer device is adapted to transfer the loading tray 150 between the first flow channel 110, the second flow channel 120, the third flow channel 130 and the fourth flow channel 140.
[0063] This invention, by setting a fourth flow channel 140, allows the transfer device to move the sorted trays 150 to the fourth flow channel 140 after the trays 150 on the third flow channel 130 have finished sorting. The tape-making device 500 is adapted to remove the products from the trays 150 on the fourth flow channel 140 and tape them. During this process, the transfer device can continue to transfer the trays 150 on the first flow channel 110 to the third flow channel 130 so that the sorting mechanism 220 can sort them, thus avoiding the sorting mechanism 220 being in a standby state and improving work efficiency. In addition, the empty trays 150 after the products are removed by the tape-making device 500 can be unloaded from the fourth flow channel 140, thereby avoiding the unloading of empty trays 150 from the third flow channel 130. This effectively prevents operators from misoperating after removing the trays 150 from the third flow channel 130 and ensures the smooth progress of subsequent processes.
[0064] Furthermore, the first flow channel 110, the second flow channel 120, and the third flow channel 130 are arranged side by side along the X-axis, and their length direction is parallel to the Y-axis. The first flow channel 110 is provided with a first loading position, a first conveying position, and a first unloading position in sequence along its length direction. The tray 150 containing the product to be tested can be loaded from the first loading position to the first flow channel 110. Then, the first flow channel 110 sequentially moves the tray 150 to the first conveying position and the first unloading position. At the first conveying position, the first conveying mechanism 210 can transport the product in the tray 150 to the testing device for appearance inspection, and then put it back into the tray 150. At the first unloading position, the transfer device can transfer the tray 150 to the third flow channel 130.
[0065] The second flow channel 120 is provided with a second loading position, a first sorting position and a second unloading position in sequence along its length. The transfer device can transfer the tray 150 on the third flow channel 130 to the second loading position. The second flow channel 120 can drive the tray 150 to the first sorting position and the second unloading position in sequence. At the first sorting position, the sorting mechanism 220 can sort the products in the tray 150. At the second unloading position, the tray 150 containing defective products can be unloaded after sorting.
[0066] The third flow channel 130 is sequentially provided with a transfer station, a third loading station, a second sorting station, and a third unloading station along its length. The transfer device can transfer the tray 150 from the first unloading station to the third loading station. The third flow channel 130 can drive the tray 150 to the second sorting station and the third unloading station in sequence. At the second sorting station, the sorting mechanism 220 can sort the products in the tray 150. At the third unloading station, the tray 150 containing qualified products after sorting can be unloaded. In addition, when it is necessary to tape the qualified products in the tray 150, the third flow channel 130 drives the tray 150 to the transfer station from the second sorting station, and the transfer device can transfer the tray 150 to the fourth flow channel 140.
[0067] Preferably, the first loading position, the first unloading position, and the second unloading position are located on the same straight line parallel to the X-axis, and are situated at one end of the flow channel, thereby facilitating the loading and unloading of the material tray 150 by the operator. A stacking mechanism 160 is provided at each of the first loading position, the first unloading position, and the second unloading position. The stacking mechanism 160 is adapted to stack and receive the material tray 150, allowing it to be lowered into the flow channel or received from the flow channel. The stacking mechanism 160 is a known structure and will not be described in detail here.
[0068] Preferably, the first conveying station, the first sorting station, and the second sorting station are located on the same straight line parallel to the X-axis, which effectively simplifies the structure of the sorting mechanism 220 and facilitates efficient reciprocating transport of products by the sorting mechanism 220. The first unloading station, the second loading station, and the third loading station are located on the same straight line parallel to the X-axis, which effectively simplifies the structure of the transfer device and facilitates efficient reciprocating transport of the material tray 150 by the transfer device.
[0069] The fourth flow channel 140 is located outside the third flow channel 130 in the X-axis direction, meaning the side of the third flow channel 130 away from the second flow channel 120. The fourth flow channel 140 has a fourth loading position, a second transport position, and a fourth unloading position sequentially along its length. The transfer position and the fourth loading position are preferably located on the same straight line parallel to the X-axis. The fourth loading position is suitable for receiving the tray 150 transferred from the third flow channel 130. The fourth flow channel 140 is suitable for driving the tray 150 to flow sequentially to the second transport position and the fourth unloading position. At the second transport position, the tape-and-reel device 500 can remove the product from the tray 150. At the fourth unloading position, it can unload empty trays 150. A stacking mechanism 160 is also provided at the fourth unloading position to stack and unload trays 150, facilitating centralized removal by operators.
[0070] Furthermore, the first flow channel 110, the third flow channel 130, and the fourth flow channel 140 have the same structure. Taking the first flow channel 110 as an example, refer to... Figure 4 and Figure 5 As shown, the first flow channel 110 includes a first guide frame 111, a first material pulling mechanism 112, and a first drive mechanism 113. The first material pulling mechanism 112 is slidably disposed on the first guide frame 111 and is adapted to slide along the Y-axis. The first drive mechanism 113 is specifically a belt drive structure, which is adapted to drive the first material pulling mechanism 112 to slide along the first guide frame 111.
[0071] The length direction of the first guide frame 111 is parallel to the Y-axis. Two guide rails 1111 are provided on the first guide frame 111, with their length directions parallel to the Y-axis. These guide rails 1111 are arranged opposite each other along the X-axis. The cross-section of each guide rail 1111 is L-shaped. The two guide rails 1111 can cooperate to support the material tray 150 and limit the material tray 150 in the X-axis direction, so that the material tray 150 can reliably move along the Y-axis.
[0072] The first material pulling mechanism 112 includes a first fixed plate 1121, a first positioning block 1122, and a first clamping assembly 1123. The first fixed plate 1121 is slidably connected to the first guide frame 111 via a slide rail structure and is located below the guide rail 1111. The first positioning block 1122 is fixed to one side of the first fixed plate 1121 on the Y-axis and protrudes upward from the guide rail 1111 along the Z-axis. The first clamping assembly 1123 is disposed on the first fixed plate 1121 and includes a first clamping block 1124 located on the other side of the first fixed plate 1121 on the Y-axis. The first clamping block 1124 has a clamping state and a released state. When the first clamping block 1124 switches from the released state to the clamping state, it is adapted to flip upward to push the material tray 150 on the side of the Y-axis, so that the material tray 150 is clamped between the first positioning block 1122 and the first clamping block 1124. When the material tray 150 switches from the clamping state to the released state, the first clamping block 1124 is adapted to flip downward to below the guide rail 1111 to avoid obstructing the first pulling mechanism 112 from moving directly below the material tray 150. The specific structure of the first clamping assembly 1123 is similar to that of the existing structure, and will not be described in detail here. Preferably, a first limiting block 1125 may also be provided on the top of the first positioning block 1122. When the first clamping block 1124 pushes the material tray 150 against the first positioning block 1122, the first limiting block 1125 blocks the material tray 150 above it to restrict the material tray 150 from moving upward away from the first pulling mechanism 112.
[0073] Furthermore, the structure of the second flow channel 120 is similar to that of the first flow channel 110, as shown in the reference. Figure 6 and Figure 7 As shown, it includes a second guide frame 121, a second pulling mechanism 122, and a second driving mechanism 123. The structure of the second guide frame 121 is the same as that of the first guide frame 111. The second pulling mechanism 122 is slidably disposed on the second guide frame 121. The structure of the second driving mechanism 123 is the same as that of the first driving mechanism 113, and it is adapted to drive the second pulling mechanism 122 to slide along the Y-axis.
[0074] The second material pulling mechanism 122 includes a second fixed plate 1221, a second positioning block 1222, and a second clamping assembly 1223. The structure of the second clamping assembly 1223 is the same as that of the first clamping assembly 1123, and there are two sets of them. Each second clamping assembly 1223 has a second clamping block 1224. The second clamping blocks 1224 of the two second clamping assemblies 1223 are located on both sides of the second fixed plate 1221 in the Y-axis direction. The second positioning block 1222 is fixed to the middle position of the second fixed plate 1221 in the Y-axis direction. A receiving area for a material tray 150 is formed between one second clamping block 1224 and the second positioning block 1222, and a receiving area for a material tray 150 is also formed between the other second clamping block 1224 and the second positioning block 1222. A second limiting block 1225 is provided at the top of the second positioning block 1222 to prevent the material tray 150 from disengaging upwards. By adopting the above structure, the second flow channel 120 can receive empty material trays 150 in addition to receiving the material trays 150 flowing out of the first flow channel 110, so as to facilitate subsequent sorting.
[0075] Preferably, the end of the second guide frame 121 corresponding to the second unloading position extends along the Y-axis with an extension section 1211. The extension section 1211 is adapted to carry an unloaded tray 150. When one of the receiving areas corresponds to the second unloading position, the other receiving area corresponds to the extension section 1211, so that the second pulling mechanism 122 pulls the tray 150 on the extension section 1211.
[0076] Furthermore, referring to Figure 1 and Figure 2As shown, the detection device includes a first lower detection mechanism 310, a second lower detection mechanism 330, and an upper detection mechanism 320. The first lower detection mechanism 310 is used to detect the back of the product, the second lower detection mechanism 330 is used to detect the side of the product, and the upper detection mechanism 320 is used to detect the front of the product. The first lower detection mechanism 310 is located outside the first flow channel 110 in the X-axis direction, which refers to the side of the first flow channel 110 away from the second flow channel 120. The first lower detection mechanism 310 and the first transport position are on the same straight line parallel to the X-axis. The second lower detection mechanism 330 is located outside the first lower detection mechanism 310 in the X-axis direction. The second lower detection mechanism 330 and the first transport position are on the same straight line parallel to the X-axis. The first transport mechanism 210 is adapted to transport the product from the tray 150 of the first transport position to the first lower detection mechanism 310 along the X-axis direction. The upper inspection mechanism 320 is mounted on the sorting mechanism 220. The sorting mechanism 220 is adapted to sort products back and forth between the first and second sorting positions along the X-axis. The upper inspection mechanism 320 is adapted to move synchronously with the sorting mechanism 220 to the top of the tray 150 of the third flow channel 130 to perform appearance inspection on the products in the tray 150. The first conveying mechanism 210 and the sorting mechanism 220 are existing structures, which drive the vacuum nozzle through the cooperation of the X-axis linear module and the Z-axis linear module to realize the conveying of products. This utility model will not be described in detail here.
[0077] Furthermore, referring to Figure 8 and Figure 9 As shown, the first lower detection mechanism 310 includes a first ring light source 311, a first back-side detection camera 312, and a second back-side detection camera 313. The axis of the first ring light source 311 is parallel to the Z-axis. The first back-side detection camera 312 is located below the first ring light source 311, with its shooting direction upward along the Z-axis and pointing towards the center of the first ring light source 311. There are several second back-side detection cameras 313, located below the first ring light source 311, evenly distributed along the circumference of the first ring light source 311, with their shooting direction inclined to the Z-axis and pointing upward towards the center of the first ring light source 311.
[0078] The first ring light source 311 includes a ring-shaped outer shell 3111 and a ring-shaped lamp plate 3112. The outer shell 3111 includes a plurality of ring portions 3113 with gradually decreasing inner diameters from top to bottom. The ring-shaped lamp plate 3112 is coaxially disposed on the ring portion 3113. There are multiple ring-shaped lamp plates 3112, and each ring portion 3113 corresponds to one of them.
[0079] Preferably, the angles between the emitted light from the multiple ring-shaped light panels 3112 and the axis of the outer shell 3111 parallel to the Z-axis are different, and the wavelength of the emitted light is adjustable. Specifically, in this embodiment, there are three ring-shaped portions 3113. The angle between the emitted light from the bottom ring-shaped light panel 3112 and the axis of the outer shell 3111 is 30°, the angle between the emitted light from the middle ring-shaped light panel 3112 and the axis of the outer shell 3111 is 45°, and the angle between the emitted light from the top ring-shaped light panel 3112 and the axis of the outer shell 3111 is 60°, thereby simulating high-angle and low-angle lighting methods, thus effectively improving the detection capability of product defects. Several LEDs in the ring-shaped light panel 3112 can emit light of different wavelengths, such as red light with a wavelength of 625nm, blue light with a wavelength of 440nm, and green light with a wavelength of 525nm. By combining these LEDs, the effect of multi-wavelength light is achieved, improving the surface recognition of products made of different materials and making it compatible with products made of multiple materials. The LED beads in the 3112 ring light board are preferably high-brightness plug-in LED beads, which have good consistency and long service life. Their light emission angle is 30°, which reduces the reflection angle, avoids stray light interference with the camera, increases image contrast, and improves the accuracy of product detection.
[0080] Furthermore, the first lower detection mechanism 310 includes a mounting frame 314, on which the first annular light source 311, the first back-side detection camera 312, and the second back-side detection camera 313 are all mounted. Preferably, the first lower detection mechanism 310 further includes an auxiliary light source 315 mounted on the mounting frame 314. The auxiliary light source 315 is also annular, with an outer diameter smaller than the minimum inner diameter of the first annular light source 311, and is coaxially located at the bottom of the first annular light source 311. The auxiliary light source 315 is adapted to irradiate the back of the product upward along the Z-axis.
[0081] Furthermore, the second inspection mechanism 330 uses a camera in conjunction with a prism to inspect the side of the product, which will not be described in detail here.
[0082] Furthermore, referring to Figure 10 and Figure 11 As shown, the upper detection mechanism 320 includes a second ring light source 321 and a front detection camera 322. The second ring light source 321 is located above the third flow channel 130, and the front detection camera 322 is located above the second ring light source 321 and is used to detect the front of the product. The shooting direction of the front detection camera 322 is downward along the Z-axis and coincides with the center of the second ring light source 321.
[0083] In this embodiment, the inner contour of the second ring light source 321 is a polygonal structure, such as a hexagon or an octagon, with an octagon being preferred in this embodiment. Compared to traditional square or circular light sources, it offers more lighting angles, meeting the lighting needs of diverse and multi-shaped products. The second ring light source 321 includes a polygonal lamp panel assembly 3211, which is composed of multiple strip lamp panels 3212. There are multiple sets of lamp panel assemblies 3211, which are arranged at intervals along the Z-axis. The emitted light from the multiple sets of lamp panel assemblies 3211 is all emitted downwards, and the angles between the emitted light and the central axis of the polygon parallel to the Z-axis are different, and the wavelength of the emitted light is adjustable.
[0084] In this embodiment, there are five sets of light panel assemblies 3211, each with a different angle. The angle between the emitted light from each light panel assembly 3211 and the central axis of the polygon, from bottom to top, is 10°, 30°, 45°, 60°, and 75°. Different angles produce different lighting effects, which can simulate a dark field for the same product, detect product surface defects, and improve the detection of abnormal products. At the same time, it can simulate a bright field to identify chip characters and mark points. The structure of the strip light panel 3212 is similar to that of the ring light panel 3112. It can also emit red, blue, and green light to improve the surface recognition of products with different materials and colors, and is compatible with products of various materials.
[0085] Furthermore, the second annular light source 321 includes fixed posts 3213 and cooling fans 3214. There are multiple fixed posts 3213, located at different vertices of the polygon. The length direction of each fixed post 3213 is parallel to the Z-axis. Strip light panels 3212 are connected between adjacent fixed posts 3213. Cooling fans 3214 are located on the outside of the light panel assembly 3211, between adjacent fixed posts 3213. Multiple cooling fans 3214 are evenly distributed along the circumference of the light panel assembly 3211. The cooling fans 3214 can blow airflow through the gaps between adjacent fixed posts 3213 to different layers of strip light panels 3212, using a physical method to dissipate heat from the light source, effectively extending its lifespan. Furthermore, the gaps between different layers of strip light panels 3212 further improve the heat dissipation of the light panel assembly 3211. In this embodiment, there are specifically four cooling fans 3214.
[0086] In addition, the second ring light source 321 also includes an outer cover 3215 and a base plate 3216. The outer cover 3216 covers the outer periphery of the lamp panel assembly 3211 and the fixing post 3213, and has a through structure in the Z-axis direction. The base plate 3216 is located at the bottom of the outer cover 3216, and has a clearance opening in the Z-axis direction corresponding to the area enclosed by the lamp panel assembly 3211. The fixing post 3213 and the cooling fan 3214 are both fixed to the bottom of the base plate 3216. The periphery of the outer cover 3215 has a hollow structure to improve the heat dissipation of the lamp panel assembly 3211. The surfaces of the outer cover 3215 and the base plate 3216 are coated with a black matte oxide coating to avoid interference from stray light on the product surface.
[0087] Furthermore, referring to Figures 1 to 3 As shown, the transfer device includes a first transfer mechanism 410 and a second transfer mechanism 420. The first transfer mechanism 410 is adapted to transfer the material tray 150 between a first unloading position, a second loading position, and a third loading position along the X-axis direction. The second transfer mechanism 420 is adapted to transfer the material tray 150 from the intermediate transfer position to the fourth loading position along the X-axis direction. The first transfer mechanism 410 and the second transfer mechanism 420 use X-axis linear modules and Z-axis linear modules in conjunction with grippers to transport the material tray 150, which will not be described in detail here.
[0088] The tape-and-reel device 500 includes a tape-and-reel mechanism 510 and a second conveying mechanism 520. The tape-and-reel mechanism 510 is arranged parallel to the fourth flow channel 140 along the Y-axis and is used for tape-and-reeling products. The tape-and-reel mechanism 510 is an existing structure and will not be described in detail here. The second conveying mechanism 520 is adapted to convey products from a second conveying position to the tape-and-reel mechanism 510 along the Y-axis. Specifically, the second conveying mechanism 520 consists of a Y-axis linear module and a Z-axis linear module working in conjunction with a suction nozzle structure to convey products.
[0089] Preferably, the length direction of the fourth flow channel 140 is parallel to the X-axis, so that the tape feeding mechanism 510, the third flow channel 130 and the fourth flow channel 140 are more compact. Since the length direction of the fourth flow channel 140 is not parallel to the length direction of the third flow channel 130, the second transfer mechanism 420 is provided with a rotating module so that the tray 150 on it can rotate 90° around the Z-axis to simultaneously match the third flow channel 130 and the fourth flow channel 140.
[0090] The working process of this fully automatic detection and sorting system is as follows: When there is no need to tape the product, the operator places an empty tray 150 on the second guide frame 121 of the second flow channel 120. The second pulling mechanism 122 moves toward the tray 150 and clamps the tray 150 in one of the receiving areas. The second pulling mechanism 122 drives the tray 150 to move to the first sorting position.
[0091] At the same time, the stacking mechanism 160 at the first flow channel 110 lowers the tray 150 containing the product to be tested to the first loading position. The first flow channel 110 transfers the tray 150 to the first transport position through the first pulling mechanism 112. The first transport mechanism 210 transports the product to the first lower inspection mechanism 310 and the second lower inspection mechanism 330 in sequence to perform appearance inspection on the back and sides of the product respectively.
[0092] After all the products in the tray 150 have been inspected, the first flow channel 110 transfers the tray 150 to the first unloading position, the first transfer mechanism 410 moves the tray 150 to the third loading position, the third flow channel 130 moves the tray 150 to the third sorting position, the sorting mechanism 220 drives the upper inspection mechanism 320 to move above the tray 150 to inspect the front of the products, and then the sorting mechanism 220 sorts the products in the tray 150 to transfer the unqualified products to the tray 150 of the second flow channel 120;
[0093] After the trays 150 on the third flow channel 130 have finished sorting, the third flow channel 130 moves the trays 150 to the third loading position. The first transfer mechanism 410 moves the trays 150 to the second loading position as a replenishment tray, which is held in another receiving space of the second pulling mechanism 122. During this process, the first transfer mechanism 410 moves back to the first flow channel 110 to move another tray 150, which has been tested on the back and sides of the product, to the third flow channel 130 for continued front-side inspection. Then, the sorting mechanism 220 transports the defective products to the second flow channel 120. After sorting is completed in tray 150, the sorting mechanism 220 fills the tray 150 of the third channel 130 with qualified products from the replenishment tray of the second channel 120. The third channel 130 unloads the tray 150 full of qualified products. The above actions are repeated. When the tray 150 of the second channel 120 is full of unqualified products, the second channel 120 unloads the tray 150 and reloads the empty tray 150. When the replenishment tray is empty, the first transfer mechanism 410 transfers the tray 150 of qualified products from the third channel 130 back to the second channel 120 as a new replenishment tray.
[0094] When product tape feeding is required, the difference lies in the initial loading process. Initially, the operator simultaneously loads two empty trays 150 into the second flow channel 120, allowing the second pulling mechanism 122 to clamp the two trays 150 and move them to the second sorting position. After the sorting mechanism 220 moves defective products from the trays 150 in the third flow channel 130 to the trays 150 in the second flow channel 120, it then organizes the products in the trays 150 of the third flow channel 130 by taking material from the back of the tray and replenishing it from the front. The first empty space is cleared to improve subsequent handling efficiency; then the third flow channel 130 moves the regulated tray 150 to the transfer position, the second transfer mechanism 420 moves the tray 150 from the transfer position to the fourth loading position, and the tray 150 moves to the second handling position under the drive of the fourth flow channel 140. The second handling mechanism 520 can transport the product to the tape-making mechanism 510 for tape-making. After the tray 150 is unloaded, the fourth flow channel 140 moves the tray 150 to the fourth unloading position for stacking and unloading.
