It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0064] As used herein, the terms "comprise," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0065] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0066] See also Figure 1 As shown, a fully automatic electrical testing system corresponding to a preferred embodiment of the present invention includes: a main tower device 100, including a first turntable 110 and a plurality of suction nozzle mechanisms 120 for picking up and placing products, the plurality of suction nozzle mechanisms 120 are evenly distributed on the first turntable 110 along the circumference of the first turntable 110, and the first turntable 110 is suitable for driving the suction nozzle mechanisms 120 to move to the transfer station; a sub-tower device 200, including a second turntable 210 and a plurality of carrier mechanisms 220, the plurality of carrier mechanisms 220 are evenly distributed on the second turntable 210 along the circumference of the second turntable 210, and the second turntable 210 is suitable for driving the carrier mechanisms 220 to move to the transfer station and the electrical testing station; an electrical testing device 300, arranged at the electrical testing station; wherein the carrier mechanism 220 includes a socket 221 that can absorb or release the product, and the socket 221 is suitable for being electrically connected to the product and the electrical testing device 300, respectively.

[0067] The present invention sets a main tower device 100 and a sub-tower device 200, and the first turntable 110 and the second turntable 210 cooperate with each other, so that the product can be continuously and quickly lowered from the suction nozzle mechanism 120 to different carrier mechanisms 220 at the transfer station, and the carrier mechanism 220 can be moved from the transfer station to the electrical testing station under the drive of the second turntable 210, so that the electrical testing device 300 is electrically connected to the socket 221 to perform electrical testing of the product, thereby realizing large-scale and efficient transfer and electrical testing of the product; in addition, the carrier mechanism 220 includes a socket 221 suitable for electrical connection with the electrical testing device 300 and the product. The socket 221 uses an adsorption method to fix or release the product, has a simple structure, and is more convenient for taking and placing products.

[0068] Furthermore, the axes of the first turntable 110 and the second turntable 210 are parallel to the vertical direction, and the first turntable 110 is located above the second turntable 210. The nozzle mechanism 120 at the transfer station is located directly above the carrier mechanism 220 at the transfer station. The nozzle mechanism 120 is suitable for vertical lifting to place products on or remove products from the carrier mechanism 220.

[0069] Furthermore, the main tower device 100 includes a mounting plate 130 located above the first rotating disk 110, and the mounting plate 130 is a fixed structure. Figures 2 to 4 As shown, the nozzle mechanism 120 includes a nozzle assembly 121 and a pressure assembly 122. The nozzle assembly 121 is mounted on the first turntable 110 to suck or release products. The pressure assembly 122 is mounted on the mounting plate 130 and cooperates with the nozzle assembly 121 to drive the nozzle assembly 121. By mounting the pressure assembly 122 on the mounting plate 130, the load-bearing capacity of the first turntable 110 can be reduced, the service life of the first turntable 110 can be increased, and the cost of use can be reduced. Of course, in other embodiments, the pressure assembly 122 can also be mounted directly on the first turntable 110.

[0070] Furthermore, in one embodiment, the first turntable 110 is provided with a hole extending through it in the vertical direction, and the suction nozzle assembly 121 is inserted into the hole and can be raised and lowered in the vertical direction. Preferably, in this embodiment, the suction nozzle assembly 121 includes a suction nozzle holder 1211 and a suction nozzle member 1212. The suction nozzle holder 1211 is fixed to a position near the edge of the first turntable 110, and the suction nozzle holder 1211 is provided with a hole extending through it in the vertical direction. The suction nozzle member 1212 can be movably inserted into the hole in the vertical direction, and in the vertical direction, the projection of the suction nozzle member 1212 does not overlap with the projection of the first turntable 110, so as not to hinder the raising and lowering of the suction nozzle member 1212. With the above structure, the first turntable 110 does not need to be provided with a hole for accommodating the suction nozzle member 1212, thereby improving versatility and facilitating the disassembly, assembly and replacement of the suction nozzle assembly 121.

[0071] Preferably, the nozzle assembly 121 includes a first linear bearing 1213 coaxially fixed in an opening in the nozzle holder 1211. The nozzle member 1212 is a round rod-shaped structure that is adapted to fit within the first linear bearing 1213 and is movable along the axial direction of the first linear bearing 1213. Since the nozzle holder 1211 has a relatively complex structure and high cost, the above-described structure prevents direct contact between the nozzle member 1212 and the nozzle holder 1211, thereby preventing wear of the nozzle holder 1211. Furthermore, after extended use, only the worn first linear bearing 1213 needs to be replaced, effectively reducing costs.

[0072] In addition, a first upper fixing block 1214 is fixed to the upper end of the suction nozzle member 1212, and a lower fixing block 1215 is fixed to the lower end, so that the suction nozzle member 1212 is limited in the vertical direction by the first upper fixing block 1214 and the lower fixing block 1215 to prevent it from separating from the suction nozzle seat 1211. In this embodiment, the upper and lower ends of the first linear bearing 1213 both protrude from the suction nozzle seat 1211, and the upper and lower ends of the suction nozzle member 1212 both extend out of the first linear bearing 1213. The first upper fixing block 1214 and the lower fixing block 1215 are fixed to the protruding portion of the suction nozzle member 1212. When the suction nozzle member 1212 moves downward to the extreme position, the first upper fixing block 1214 can abut against the upper end of the first linear bearing 1213. When the suction nozzle member 1212 moves upward to the extreme position, the lower fixing block 1215 can abut against the lower end of the first linear bearing 1213.

[0073] Furthermore, the downward pressure assembly 122 includes a first mounting seat 1221, a pressure rod 1222, and a downward pressure driving member 1223. The first mounting seat 1221 is disposed on the mounting plate 130 and is located above the suction nozzle assembly 121. The first mounting seat 1221 has an opening extending vertically therethrough, and the opening on the first mounting seat 1221 is coaxial with the opening on the suction nozzle seat 1211. The pressure rod 1222 is disposed in the opening of the first mounting seat 1221 and can be raised and lowered vertically.

[0074] Preferably, a second linear bearing 1224 is fixed in the opening, and the pressure rod 1222 is adapted to be inserted into the second linear bearing 1224. The second linear bearing 1224 does not protrude relative to the first mounting seat 1221. The upper and lower ends of the pressure rod 1222 both extend out of the first mounting seat 1221. A second upper fixing block 1225 is fixed to the upper end of the pressure rod 1222 to prevent the pressure rod 1222 from disengaging from the first mounting seat 1221. The lower end of the pressure rod 1222 abuts against the upper end of the nozzle member 1212.

[0075] The downward driving member 1223 is fixed to the mounting plate 130. A cam 1226 is provided at the output end of the downward driving member 1223. The cam 1226 pushes the pressing rod 1222 downward in response to the action of the downward driving member 1223. Specifically, the downward driving member 1223 is a rotary motor whose rotation axis is parallel to the vertical direction. The upper end of the pressing rod 1222 is provided with a first follower 1227. The first follower 1227 is specifically a cam bearing follower, which is fixed to the second upper fixed block 1225. The first follower 1227 contacts the cam 1226. When the downward driving member 1223 drives the cam 1226 to rotate, the first follower 1227 is adapted to move downward under the push of the cam 1226.

[0076] Preferably, the suction nozzle mechanism 120 includes a first reset member 123 acting on the suction nozzle assembly 121 and a second reset member 124 acting on the pressing assembly 122. The first reset member 123 is suitable for driving the suction nozzle assembly 121 to rise and reset so that the pressure rod 1222 can reliably act on the suction nozzle member 1212. The second reset member 124 is suitable for driving the pressure rod 1222 to rise and reset so that the first follower 1227 always contacts the cam 1226, ensuring that the cam 1226 can reliably act on the pressure rod 1222.

[0077] Specifically, the first return member 123 and the second return member 124 are both springs. The first return member 123 is sleeved outside the suction nozzle member 1212, and its two ends are abutted between the suction nozzle seat 1211 and the first upper fixed block 1214. The second return member 124 is sleeved outside the pressure rod 1222, and its two ends are abutted between the first mounting seat 1221 and the second upper fixed block 1225. Preferably, the upper end of the second linear bearing 1224 is recessed inward relative to the top of the first mounting seat 1221, and the lower end of the second return member 124 is received in the opening and abutted against the second linear bearing 1224 to improve the reliability of the second return member 124 after installation.

[0078] Further, refer to Figures 5 to 7 As shown, the top surface of the socket 221 is recessed inward to form a receiving groove 2211, which is suitable for positioning and adsorbing products. The inner contour of the receiving groove 2211 matches the outer contour of the product. The inner wall of the receiving groove 2211 is provided with an electrical connection structure to electrically connect the product placed in the receiving groove 2211 to the socket 221. The bottom of the receiving groove 2211 is provided with a suction hole, which is connected to the external vacuum generating structure to provide suction force to the bottom of the receiving groove 2211 to attract the product.

[0079] However, with the above structure, during the high-speed rotation of the second turntable 210, the product may fly out of the receiving groove 2211 under the action of centrifugal force. As a preferred embodiment, the carrier mechanism 220 includes a carrier seat 222, a cover assembly 223 and a transmission assembly 224. The carrier seat 222 is arranged on the second turntable 210, and the socket 221 is arranged on the carrier seat 222. The cover assembly 223 is arranged on the carrier seat 222, and the cover assembly 223 can be moved in the horizontal direction to a closed state to cover the receiving groove 2211, or moved to an open state to open the receiving groove 2211. The transmission assembly 224 is connected to the cover assembly 223, and the sub-tower device 200 includes a switching mechanism 230 located at the transfer station. The transmission assembly 224 is suitable for driving the cover assembly 223 to switch to the open state under the drive of the switching mechanism 230, and when the switching mechanism 230 is deactivated, the cover assembly 223 is suitable for resetting from the open state to the closed state. By adopting the above structure, the switching mechanism 230 does not need to be set on the second turntable 210, which reduces the burden on the second turntable 210, and only one needs to be set, which simplifies the structure of the sub-tower device 200 and improves the service life of the second turntable 210. When the carrier mechanism 220 moves to the transfer station, the switching mechanism 230 can act on the cover assembly 223 to switch it to an open state to avoid hindering the removal and placement of products. When the switching mechanism 230 does not act on the cover assembly 223, it can be reset to a closed state, thereby preventing the product from flying out of the receiving groove 2211 from the carrier mechanism 220.

[0080] Specifically, the second turntable 210 is recessed inward from its outer peripheral side to form a first mounting groove 211, and the first mounting groove 211 passes through the top and bottom of the second turntable 210 in the vertical direction. The carrier seat 222 is fixedly embedded in the first mounting groove 211. There are multiple first mounting grooves 211, and they correspond one-to-one to the carrier seats 222.

[0081] The carrier base 222 has a first mounting hole 2221 extending vertically therethrough. The socket 221 is secured within the first mounting hole 2221. The bottom of the socket 221 is provided with an electrical connection structure for electrically connecting to the electrical measuring device 300. A second mounting slot 2222 is formed vertically inwardly from the top surface of the carrier base 222. The cover assembly 223 is mounted within the second mounting slot 2222. A second mounting hole 2223 extends vertically therethrough. The transmission assembly 224 is vertically mounted within the second mounting hole 2223 so as to be liftable therein.

[0082] The length direction of the carrier seat 222 is parallel to the recessed direction of the first mounting groove 211. The first mounting hole 2221, the second mounting groove 2222 and the second mounting hole 2223 are arranged side by side along the length direction of the carrier seat 222, and the first mounting hole 2221 is close to the slot opening of the first mounting groove 211, the second mounting hole 2223 is close to the bottom of the first mounting groove 211, and the second mounting groove 2222 is located between the first mounting hole 2221 and the second mounting hole 2223.

[0083] The cover assembly 223 includes a cover 2231 and connecting posts 2232. The ends of the connecting posts 2232 are fixed to opposite inner walls of the second mounting slot 2222. The cover 2231 is mounted over the connecting posts 2232 and is slidable along them. In this embodiment, the axial direction of the connecting posts 2232 is parallel to the width of the carrier 222. The cover 2231 is received in the second mounting slot 2222 and mounted over the connecting posts 2232. The cover 2231 partially extends out of the second mounting slot 2222 to form a cover portion that covers the socket 221 and is adapted to slide along the axial direction of the connecting posts 2232 to seal or open the receiving slot 2211.

[0084] Preferably, there are two cover plates 2231 arranged side by side along the width of the carrier base 222. The two cover plates 2231 are adapted to move toward each other under the drive of the transmission assembly 224 to close the receiving slot 2211, or move away from each other to open the receiving slot 2211. By adopting this structure, the movement path of a single cover plate 2231 can be shortened, thereby improving opening and closing efficiency.

[0085] The transmission assembly 224 includes a transmission plate 2241, a second follower 2242, and a third reset member 2243. The transmission plate 2241 can be vertically raised and lowered within the second mounting hole 2223. The transmission plate 2241 is provided with two guide holes 2244 extending along the length of the carrier base 222. The guide holes 2244 are strip-shaped and arranged in an "eight" pattern. The distance between the upper ends of the two guide holes 2244 is smaller than the distance between the lower ends. A notch 2224 is provided between the second mounting slot 2222 and the second mounting hole 2223. The second follower 2242 is secured to the cover plate 2231 and is at least partially embedded in the guide hole 2244 through the notch 2224. The second follower 2242 corresponds one-to-one with the cover plate 2231 and / or the guide holes 2244. The transmission plate 2241 has a protrusion 2245 that opposes the bottom of the carrier seat 222. The third return member 2243 is specifically a spring whose expansion and contraction direction is parallel to the vertical direction. The third return member 2243 is positioned between the bottom of the carrier seat 222 and the protrusion 2245. The third return member 2243 is adapted to provide a force that drives the transmission plate 2241 downward, causing the second follower 2242 to abut against the upper end of the guide hole 2244. The switching mechanism 230 is adapted to lift the transmission plate 2241. The guide hole 2244 is adapted to rise to move the two cover plates 2231 away from each other to an open state. When the switching mechanism 230 descends, the guide hole 2244 is adapted to descend due to the rebound action of the third return member 2243, driving the cover plates 2231 to move toward each other to a closed state.

[0086] Furthermore, the switching mechanism 230 includes a second mounting seat 231, a lifting drive member 232 and a third follower 233. The lifting drive member 232 is arranged on the second mounting seat 231. The lifting drive member 232 is specifically a linear cylinder arranged along the vertical direction. The output end of the lifting drive member 232 is fixed with a connecting block 234. The third follower 233 is installed on the connecting block 234 and corresponds to the bottom of the transmission plate 2241. The lifting drive member 232 is suitable for driving the third follower 233 to rise to lift the transmission plate 2241.

[0087] Further, refer to Figure 1 、 Figure 8 and Figure 9 As shown, there are preferably multiple electrical testing stations, arranged sequentially along the transfer path of the carrier mechanism 220. Each electrical testing device 300 corresponds to each testing station, improving electrical testing efficiency. Specifically, there are N electrical testing devices 300 and 2N carrier mechanisms 220. The product is a photosensitive chip, and the electrical testing device 300 needs to illuminate the photosensitive area of ​​the product for photosensitivity testing.

[0088] In this embodiment, the electrical measuring device 300 includes a first mounting frame 310, an electrical measuring mechanism 320, a light source mechanism 330, a connecting rod mechanism 340, and a connecting rod driver 350. The electrical measuring mechanism 320 is vertically movable on the first mounting frame 310 and is located below the second turntable 210. It can be raised to electrically connect with the socket 221 or lowered to disconnect. Specifically, the electrical measuring mechanism 320 includes a first lifting plate 321 and an electrical measuring board 322 mounted on the first lifting plate 321. The first lifting plate 321 is slidably connected to the first mounting frame 310 via a slide rail structure. The electrical measuring board 322 is a PCB located below the socket 221. The top of the electrical measuring board 322 is equipped with a connection structure that mates with the electrical connection structure at the bottom of the socket 221.

[0089] The light source mechanism 330 is located above the second turntable 210 and can be vertically raised and lowered on the first mounting frame 310. It can be lowered to approach the product so that the product can be reliably illuminated, or raised to avoid the second turntable 210. The light source mechanism 330 includes a second lifting plate 331 and a light source 332 mounted on the second lifting plate 331. The second lifting plate 331 is slidably connected to the first mounting frame 310 via a slide rail structure. The output end of the light source 332 faces the cover plate 2231. The cover plate 2231 is provided with an avoidance portion 2233 corresponding to the light source mechanism 330 along the vertical direction. The avoidance portion 2233 avoids the photosensitive area of ​​the product, and the product will not escape from the receiving groove 2211 through the avoidance portion 2233.

[0090] The connecting rod mechanism 340 is connected to the electric measuring mechanism 320 and the light source mechanism 330, respectively. The connecting rod driver 350 is disposed on the first mounting frame 310 and is in transmission connection with the connecting rod mechanism 340. Driven by the connecting rod driver 350, the connecting rod mechanism 340 is adapted to drive the electric measuring mechanism 320 and the light source mechanism 330 to move toward or away from each other in the vertical direction. The connecting rod mechanism 340 comprises a rotating shaft 341, a lever 342, a short connecting rod 343, and a long connecting rod 344. The rotating shaft 341 is rotatably connected to the first mounting frame 310, with its axis parallel to the horizontal direction. The lever 342 is located below the electric measuring mechanism 320 and fixedly sleeved around the rotating shaft 341. One end of the short connecting rod 343 is hinged to one end of the lever 342, and the other end is hinged to the first lifting plate 321. One end of the long connecting rod 344 is hinged to the other end of the lever 342, and the other end is hinged to the second lifting plate 331. The connecting rod driver 350 is a rotary motor, whose output end is connected to the rotating shaft 341 to drive the rotation of the rotating shaft 341 and the lever 342. When the electrical measuring device 300 needs to cooperate with the carrier mechanism 220, the lever 342 rotates clockwise. One end of the lever 342 is adapted to push the first lifting plate 321 upward, while the other end is adapted to pull the second lifting plate 331 downward, so that the electrical measuring device 320 and the light source mechanism 330 move toward each other and toward the carrier mechanism 220. When the electrical measuring device 300 needs to separate from the carrier mechanism 220, the lever 342 rotates counterclockwise. One end of the lever 342 is adapted to pull the first lifting plate 321 downward, while the other end is adapted to push the second lifting plate 331 upward, so that the electrical measuring device 320 and the light source mechanism 330 move away from the carrier mechanism 220.

[0091] Furthermore, the first turntable 110 is suitable for driving the nozzle mechanism 120 to move to the loading station, the transfer station, the appearance inspection station and the unloading station in sequence. Figures 10 to 13 As shown, the fully automatic electrical testing system includes a loading device 400, an appearance inspection device 500, and an unloading device 600. The loading device 400 is located at the loading station and is used to load products to be tested. The appearance inspection device 500 is located at the appearance inspection station and is used to inspect the appearance of the products. The unloading device 600 is located at the unloading station and is suitable for unloading products. After the product on the sub-tower device 200 undergoes electrical testing, the main tower device 100 is suitable for removing the product from the sub-tower device 200 at the transfer station and transferring it to the appearance testing station and the unloading station in sequence.

[0092] The loading device 400 utilizes a vibrating plate for loading, and the appearance inspection device 500 uses a camera to capture the product's exterior surface to obtain appearance information. This description is omitted here. The unloading device 600 includes a sorting mechanism 610, a taping mechanism 620, and a first waste discharge mechanism 630. The sorting mechanism 610 receives and categorizes qualified products, the taping mechanism 620 receives and taps qualified products, and the first waste discharge mechanism 630 receives unqualified products.

[0093] The sorting mechanism 610 includes a second mounting frame 611, a hopper 612, a first feed pipe 613, a sorting drive 614, and a first hopper 615. The hopper 612 is mounted on the second mounting frame 611 to receive products dropped from the suction nozzle mechanism 120. The first feed pipe 613 is rotatably connected to the second mounting frame 611. One end of the first feed pipe 613 is located directly below the hopper 612, abutting the bottom of the hopper 612, and the other end extends downward at an angle. The first hopper 615 is located below the first feed pipe 613. There are multiple first hoppers 615 with open tops. In response to rotation, the first feed pipe 613 rotates so that its lower end aligns with the top of different first hoppers 615. These multiple first hoppers 615 are suitable for accommodating different types of products. The sorting drive 614 is a rotary motor, which is connected to the first feed pipe 613 via a belt structure 616 to drive its rotation.

[0094] Furthermore, the taping mechanism 620 is an existing chip taping machine and will not be described in detail herein. The first waste discharge mechanism 630 includes a magazine frame 631 and a second magazine 632. The side of the magazine frame 631 is open for loading and unloading the second magazine 632. A second feed pipe 633 is provided at the top of the magazine frame 631. The second feed pipe 633 extends into the magazine frame 631 to correspond to the open top of the second magazine 632. The nozzle mechanism 120 is adapted to feed unqualified products into the top of the second feed pipe 633. The products are guided by the second feed pipe 633 and fall into the second magazine 632.

[0095] Because the loading device 400 utilizes a vibrating plate loading structure, it has difficulty positioning the product. This results in poor product positioning accuracy after the suction nozzle mechanism 120 absorbs the product. As a preferred embodiment, an adjustment station is provided between the loading station and the transfer station. The fully automatic electrical testing system includes an adjustment device 700 located at the adjustment station. The adjustment device 700 includes a direction determination mechanism 710, a rotation adjustment mechanism 720, and a second waste discharge mechanism 730. The direction determination mechanism 710 is adapted to photograph the product on the suction nozzle mechanism 120. The rotation adjustment mechanism 720 is adapted to receive the product from the suction nozzle mechanism 120 and adjust the product's position based on the photographic results of the direction determination mechanism 710. The second waste discharge mechanism 730 is adapted to receive unqualified products. After the suction nozzle mechanism 120 absorbs the product from the loading device 400, the first turntable 110 is adapted to drive the suction nozzle mechanism 120 to sequentially pass through the direction determination mechanism 710, the rotation adjustment mechanism 720, and the second waste discharge mechanism 730. The direction determination mechanism 710 is a visual structure located below the suction nozzle mechanism 120. It captures an image of the product's position and can also perform a rough inspection of the product's appearance to eliminate clearly unqualified products. The rotation adjustment mechanism 720 is a rotating suction table that is suitable for receiving products and rotating around an axis parallel to the vertical direction to adjust the product's angle. The suction nozzle mechanism 120 can remove the adjusted product. The structure of the second waste discharge mechanism 730 is the same as that of the first waste discharge mechanism 630. Qualified products with adjusted angles can be transferred from the suction nozzle mechanism 120 to the carrier mechanism 220, while unqualified products can be placed in the second waste discharge mechanism 730.

[0096] The working process of the fully automatic electrical testing system of the present invention is as follows: the suction nozzle mechanism 120 is driven by the first turntable 110 to move to the loading device 400 to suck the product to be tested; then the suction nozzle mechanism 120 flows in sequence to the direction determination mechanism 710, the rotation adjustment mechanism 720 and the second waste discharge mechanism 730. At the direction determination mechanism 710, the direction determination mechanism 710 can take a picture of the product to obtain the position of the product. The rotation adjustment mechanism 720 can receive the product on the suction nozzle mechanism 120 to rotate and position the product. If the product is unqualified, the suction nozzle mechanism 120 does not need to place the product on the rotation adjustment mechanism 720, and it can directly put the product into the second waste discharge mechanism 730; then the suction nozzle mechanism 120 takes out the positioned product and flows to the transfer station to place the product on the carrier mechanism 220. The above-mentioned actions are repeated until all N carrier mechanisms 220 are loaded with products. At this time, the N carrier mechanisms 220 loaded with products correspond one-to-one to the electrical testing devices 300. As the second turntable 210 rotates, multiple electrical testing devices 300 can simultaneously perform electrical tests on the products. The carrier mechanism 220 carrying the tested products moves back to the transfer station, and the nozzle mechanism 120 takes the products off the carrier mechanism 220 and transfers them to the appearance inspection device 500, the sorting mechanism 610, the taping mechanism 620 and the first waste discharge mechanism 630 in sequence. The appearance inspection device 500 can perform appearance inspection on the products after the electrical test. Qualified products can be selectively flowed into the sorting mechanism 610 or the taping mechanism 620 according to actual needs to achieve sorting or taping, and unqualified products directly flow into the first waste discharge mechanism 630.
