Description

Technical Field

[0001] This invention relates to the field of semiconductor testing tray transfer technology, specifically a multi-directional transfer device for testing trays. Background Technology

[0002] Semiconductors are a core component of modern electronic devices, such as the CPU of a computer and the processor of a mobile phone, which realize various complex calculation and control functions. In the semiconductor production or testing environment, multi-directional transfer equipment for test trays is required. The purpose is to efficiently and accurately transfer trays carrying products (such as wafers, electronic chips, etc.) between different testing stations, processing equipment or storage areas. In order to ensure that the products are not damaged, the products are mostly placed on the trays, and the multi-directional transfer equipment only needs to transfer the trays.

[0003] Different products need to be tested after production. Different products need to be tested by different testing machines. The current multi-directional transfer equipment is like a distributor, which can transfer different products to the appropriate testing machine conveyor belt. However, the current multi-directional transfer equipment needs to use a conveyor to transport the pallet to the transfer tray, and then use the transfer tray to transfer the pallet to the different testing machine conveyor belt.

[0004] However, to save space, trays containing products are often stacked together (the products on stacked trays may be different). Existing multi-directional transfer equipment cannot sequentially pick up these stacked trays and transfer them onto a transfer tray, reducing the flexibility of the equipment. Secondly, current transfer trays can only support the trays, not stabilize them during transfer. During multi-directional movement, acceleration, deceleration, and turning operations in each direction generate varying degrees of vibration and sway, easily causing the trays to shift on the transfer tray. This makes it difficult to quickly and accurately transfer the trays onto the conveyor belt of the testing machine, affecting the transfer efficiency. Therefore, we propose a multi-directional transfer device for testing trays. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example: Figure 1-9 As shown, the present invention provides a multi-directional transfer device for detection trays, including a support box 1, a material placement base on the top of the support box 1 for placing stacked trays, a material picking mechanism 4 on the top of the support box 1, a transfer mechanism 2 on the top of the support box 1, and three sets of conveying devices 6 on the top of the support box 1.

[0033] The transfer mechanism 2 includes a transfer plate 200 on the top of the support box 1, a stabilizing mechanism 3 on the top of the transfer plate 200, a support tube 202 installed through the top of the transfer plate 200, a partition on the inner wall of the support box 1, one end of the support tube 202 connected to a bearing on the top of the partition, a driven pulley 201 sleeved on the outer wall of the support tube 202, a motor 205 on the top of the partition, a drive pulley 204 connected to the output end of the motor 205, and a belt 203 sleeved on the outer wall of the drive pulley 204 and the driven pulley 201.

[0034] By adopting the above technical solution, the transfer tray 200 can be rotated, and the product on the tray can be rotated to be aligned with the conveying device 6, so that the product can enter the corresponding testing machine for product testing.

[0035] The stabilizing mechanism 3 includes a fixed frame 300 on the top of the transfer tray 200, a pushing mechanism 5 on the outer wall of the fixed frame 300, four sets of fixed brackets 305 on the top of the fixed frame 300, each of the four sets of fixed brackets 305 having a pressing block 304 hinged inside, a connecting plate 301 inside the fixed frame 300, four sets of hinge seats 306 on the outer wall of the connecting plate 301, each of the four sets of hinge seats 306 having a rotating block 307 hinged inside, one end of the rotating block 307 being connected to the outer wall of the pressing block 304, a sliding plate 308 slidably connected inside the support tube 202, a second spring 311 at the bottom of the sliding plate 308, one end of the second spring 311 being connected to the bottom of the support tube 202, a lifting rod 302 on the top of the sliding plate 308, one end of the lifting rod 302 being connected to the bottom of the connecting plate 301, a first spring 309 sleeved on the outer wall of the lifting rod 302, one end of the first spring 309 being... The first spring 309 is connected to the top of the inner wall of the support tube 202, and the other end of the first spring 309 is connected to the top of the sliding plate 308. The outer wall of the sliding plate 308 is provided with a fixing block 310, and the outer wall of the support tube 202 is provided with a sliding groove. The fixing block 310 is slidably connected in the sliding groove. Under the action of the sliding groove, the fixing block 310 moves up and down more stably. The bottom of the fixing block 310 is provided with a pressing rod 312. The outer wall of the support tube 202 is fitted with a connecting ring 314. The top of the connecting ring 314 is rotatably provided with a support ring 303. The top of the support ring 303 is provided with a groove 313. The outer wall of the connecting ring 314 is provided with a horizontal plate 316. One end of the horizontal plate 316 is connected to the inner wall of the support box 1. The outer wall of the support ring 303 is provided with multiple sets of teeth 318. The bottom of the horizontal plate 316 is provided with a drive motor 315. The output end of the drive motor 315 is connected to a first gear 317 that meshes with the teeth 318.

[0036] By adopting the above technical solution, the carrier plate placed on the push plate 504 can be pressed and fixed under the action of the stabilizing mechanism 3, so that it will not be displaced during the transfer. If displacement occurs, the carrier plate will deviate from the conveying device 6, affecting the transfer effect. When it is necessary to loosen the carrier plate, the rotating support ring 303 is used to make the groove 313 cooperate with the corresponding conveying device 6, so that the pressing rod 312 will move downward on the support ring 303. The pressing rod 312 drives the fixing block 310 and the sliding plate 308 to move downward. The sliding plate 308 drives the lifting rod 302 to move downward, thereby realizing the downward movement of the connecting plate 301. The downward movement of the connecting plate 301 will produce a chain reaction. The connecting plate 301 will loosen the pressing block 304, thereby loosening the carrier plate. At the same time, the push plate 504 and the carrier plate will be pushed out, and the conveying device 6 can convey the carrier plate into the testing machine for testing.

[0037] The pushing mechanism 5 includes four sets of movable rods 505 that are movably connected through the outer wall of the fixed frame 300. Each set of movable rods 505 has a pushing plate 504 at one end and a sliding block 501 at the other end. The top of the transfer plate 200 has a guide groove, and the bottom of each sliding block 501 has a guide block that matches the guide groove. Under the action of the guide groove and the guide block, the sliding plate 501 is more stable when moving. The bottom of each connecting plate 301 has a pressing block 500 that matches the sliding block 501. Each set of movable rods 505 has a return spring 502 sleeved on the outer wall. One end of the return spring 502 is connected to the outer wall of the sliding block 501, and the other end of the return spring 502 is connected to the inner wall of the fixed frame 300.

[0038] By adopting the above technical solution, the connecting plate 301 moves downward, and the inclined surface of the pressing block 500 presses the inclined surface of the sliding block 501. As a result, the sliding block 501 presses the movable rod 505 and the return spring 502. The movable rod 505 pushes out the push plate 505, and the clamping block 304 is in the open state. Then, the suction head 408 places the carrier plate on the push plate 504 to realize the feeding. At the same time as feeding, the remaining three sets of push plates 504 are also pressed out. The push plates 504 with carrier plates will be pushed to contact the conveying device 6. Then the carrier plates will be conveyed out by the corresponding conveying device 6, realizing the simultaneous feeding and unloading. Then the connecting plate 301 moves upward, the pressing block 500 and the sliding block 501 separate, and the push plate 504 is reset under the action of the return spring 502. At the same time, the clamping block 304 rotates downward and clamps and fixes the carrier plate.

[0039] Both the extrusion block 500 and the sliding block 501 are arranged in the shape of a right-angled trapezoid, and the inclined surface of the sliding block 501 is in contact with the inclined surface of the extrusion block 500.

[0040] By adopting the above technical solution, when the extrusion block 500 moves downward, it will extrude the sliding block 501, thereby extruding the movable rod 505 by the sliding block 501.

[0041] Four sets of push plates 504 are arranged in a rectangular array outside the fixed frame 300, and the push plates 504 are arranged in an L shape.

[0042] By adopting the above technical solution, four sets of push plates 504 can cooperate with three sets of conveying devices 6 and the discharge point. When the adsorption head 408 places the tray on the push plate 504, a section of the tray is located on the outer wall of the push plate 504 (which facilitates contact between the tray and the conveying device 6). Thus, when the push plate 504 pushes the tray, the tray can contact the conveying device 6. The conveying device 6 then uses the friction of the conveyor belt to transport the tray. The conveying device 6 is equipped with a limiting device to limit the tray (this is the prior art), so that it can be stably transported to the testing machine for testing.

[0043] The material handling mechanism 4 includes a guide rail 400 on the top of the support box 1. A guide block 401 is slidably sleeved on the outer wall of the guide rail 400. A mounting plate 402 is provided on the outer wall of the guide block 401. A first guide strip 403 is provided on the right side wall of the mounting plate 402. A first slider 404 is slidably connected to the outer wall of the first guide strip 403. A second slider 406 is provided on the outer wall of the first slider 404. A second guide strip 405 is slidably connected to the outer wall of the second slider 406. A fixing plate 407 is provided on the outer wall of the second guide strip 405. An adsorption head 408 is provided at one end of the fixing plate 407. A second rotating shaft 409 is rotatably connected to the outer wall of the fixing plate 407. A rotating block is provided at one end of the second rotating shaft 409. 417. A first rotating shaft 418 is provided on the outer wall of the rotating block 417. A second gear 409 is provided at one end of the first rotating shaft 418. A third guide bar 411 is provided on the left side wall of the mounting plate 402. A third slider 412 is slidably connected to the outer wall of the third guide bar 411. A rack 410 matching the first gear 409 is provided at the top of the third slider 412. A first connecting rod 413 is hinged to the outer wall of the third slider 412. A second connecting rod 414 is hinged to one end of the first connecting rod 413. A rotary motor 415 is provided on the left side wall of the mounting plate 402. A disk 416 is connected to the output end of the rotary motor 415. One end of the second connecting rod 414 is hinged to the left side wall of the disk 416.

[0044] By adopting the above technical solution, the trays stacked on the material placement base can be picked up from top to bottom and placed on the push plate 504 of the transfer tray 200.

[0045] The mounting plate 402 has a positioning groove on its outer side wall, and the rotating block 417 has a positioning block on its outer side wall that matches the positioning groove.

[0046] By adopting the above technical solution, the rotation path of the rotating block 417 can be limited under the action of the positioning groove and the positioning block, thereby controlling the movement path of the adsorption head 408, so that the adsorption head 408 can be located above the material placement base when picking up materials, and above the push plate 504 when discharging materials.

[0047] Working principle: When it is necessary to transfer pallets containing products, the stacked pallets are placed on the material placement base. The guide block 401 drives the mounting plate 402 to move upward on the outer wall of the guide rail 400. After moving to the appropriate position, the rotary motor 415 drives the disc 416 to rotate. The disc 416 drives the first connecting rod 413 and the second connecting rod 414 to move in a circle. The first connecting rod 413 drives the third slider 412 to move left and right on the outer wall of the third guide bar 411. The third slider 412 drives the rack 410 to move. The rack 410 drives the second gear 409 to rotate. The second gear 409 drives the first rotating shaft 418 and the rotating block 417 to rotate. The rotating block 417 drives the second rotating shaft 419 and the fixed plate 407 to rotate. With the cooperation of the first guide bar 403, the fixed plate 407 can move left and right. Under the action of the second slider 406 and the second guide bar 405, the fixed plate 407 moves up and down, thereby driving the adsorption head 408 to move back and forth left and right. Thus, the adsorption head 408 can adsorb the carrier and move it above the transfer tray 200. Then, the guide block 401 drives the mounting plate 402 to move downward. The adsorption head 408 places the adsorbed and fixed carrier on the push plate 504 (this is where the extrusion block 500 and the sliding block 501 extrude, and the extrusion rod 312 is located in the groove 313 of the support ring 303). Then, the drive motor 315 drives the gear 317 to rotate. The gear 317 drives the teeth 314 to rotate. The teeth 314 drive the support ring 303 to rotate. When the extrusion rod 312... When the support ring 303 is moved to the top, the pressing rod 312 drives the fixed block 310 and the sliding plate 308 to move upward. The sliding plate 308 drives the lifting rod 302 to move upward, thereby enabling the connecting plate 301 to move upward. The upward movement of the connecting plate 301 will cause a chain reaction, separating the pressing block 500 and the sliding block 501. Under the action of the return spring 502, the plate 504 is pushed to reset. At the same time, the connecting plate 301 will drive the rotating block 307 to rotate. The rotating block 307 drives the pressing block 304 to press and fix the carrier plate. Then, the motor 205 drives the driving pulley 204 to rotate. The driving pulley 204 drives the belt 203 to rotate. The belt 203 drives the driven pulley 201 to rotate. The driven pulley 201 drives the support ring 303 to rotate. The support tube 202 rotates, causing the transfer disk 200 to rotate. The transfer disk 200 then rotates the carrier disk. When it rotates to engage with the corresponding conveying device 6, the drive motor 315 drives the gear 317 to rotate. The gear 317 drives the teeth 314 to rotate, which in turn drives the support ring 303 to rotate. When the pressing rod 312 moves into the groove 313, it moves downward on the support ring 303. This causes the pressing rod 312 to move the fixed block 310 and the sliding plate 308 downward. The sliding plate 308 then drives the lifting rod 302 downward, thus enabling the connecting plate 301 to move downward. The downward movement of the connecting plate 301 creates a chain reaction, causing it to release the clamping block 304.The carrier tray is released, and simultaneously the pusher plate 504 and the carrier tray are pushed out. The conveyor device 6 can transport the carrier tray into the testing machine for testing, while the suction head 408 can place the carrier tray on the pusher plate 504 to achieve loading, realizing simultaneous loading and unloading.
