Description

Technical Field

[0001] This utility model belongs to the field of testing equipment, and in particular relates to an electronic component sorting system. Background Technology

[0002] In the production process of electronic components, component sorting technology directly affects the quality and reliability of the final product. Traditional sorting systems typically employ a multi-pallet assembly line layout, where pallets containing electronic components are sequentially transported via conveyor tracks for inspection and sorting.

[0003] However, the existing layout has a significant efficiency bottleneck: when a defective product is detected and rejected on a pallet (e.g., the first pallet), the system needs to repeatedly pick up good products from subsequent pallets (e.g., the second pallet) to replenish the previous pallet, it then becomes empty due to the rejection of defective products and needs to continue picking up good products from the third pallet. This progressive compensation mechanism not only prolongs the unloading cycle of a single pallet but also causes congestion on the conveyor track, resulting in low actual equipment efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an electronic component sorting system that improves the sorting efficiency of electronic components.

[0005] To achieve the above objectives, the electronic component sorting system of this utility model includes: Multiple conveyor tracks are spaced apart along a first direction for conveying material trays; these are a feeding track, a defective product discharge track, a good product discharge track, and a buffer track; the buffer track is used to provide good products and defective products to the good product discharge track and the defective product discharge track, respectively. Testing institutions are used to detect defects in components under test. A tray handling mechanism is used to move trays between multiple conveyor tracks; The sorting mechanism is used to remove defective products from the good product discharge track and the buffer track and send them to the defective product discharge track, and to pick up good products from the buffer track to replenish the good product discharge track.

[0006] In one embodiment of the electronic component sorting system of this utility model, the electronic component sorting system further includes an empty material tray stacking mechanism, which is disposed on one side of the feeding track, and the material tray conveying mechanism conveys the empty material tray from the empty material tray stacking mechanism to the defective product discharge track.

The first detection module is disposed below one side of the feeding track, and the second detection module is disposed above the good product discharge track and the buffer track and can reciprocate between the two conveying tracks.

[0008] In one embodiment of the electronic component sorting system of this utility model, the electronic component sorting system further includes a picking mechanism, which is used to pick up multiple components to be tested and reciprocate between the first detection module and the feeding track.

The picking mechanism and the sorting mechanism are both slidably mounted on the first support frame. The material tray conveying mechanism and the second detection module are both slidably mounted on the second support frame. The second direction is perpendicular to the first direction in the horizontal plane.

[0010] In one embodiment of the electronic component sorting system of this utility model, two picking mechanisms are provided, and the first detection module is driven to move along the second direction.

[0011] In one embodiment of the electronic component sorting system of this utility model, the picking mechanism includes a mounting frame, an adsorption module and a pressing module, wherein the adsorption module is pressed against the mounting frame by the pressing module.

The pressing wheel is elastically mounted on the clamping mounting plate through a first pressing member. The pressing wheel and the mounting frame press against the upper and lower surfaces of the adsorption module, respectively.

[0014] In one embodiment of the electronic component sorting system of this utility model, the side wall of the pressing mounting plate facing the pressing module is further provided with a second pressing member for pressing the side surface of the adsorption module.

[0015] In summary, the electronic component sorting system of this utility model uses a buffer track to replenish the trays on the good product discharge track and the defective product discharge track with good and defective products respectively.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0022] like Figure 1As shown, an embodiment of the electronic component sorting system of this utility model is used to classify and unload good and defective products in a tray. The electronic component sorting system includes multiple conveyor tracks 100 spaced apart along a first direction A. The multiple conveyor tracks 100 are a loading track 110, a defective product unloading track 120, a good product unloading track 130, and a buffer track 140. Each of the multiple conveyor tracks 100 has a first end 150 and a second end 160 along a second direction B, and the second direction B is perpendicular to the first direction A in a horizontal plane. The feeding track 110 is used to convey a full tray containing components to be tested from the first end 150 to the second end 160; the defective product discharge track 120 is used to unload a full tray containing defective products from the first end 150; the good product discharge track 130 is used to unload a full tray containing good products from the first end 150; the buffer track 140 is used to temporarily store full trays and to replenish good and defective products to the trays on the good product discharge track 130 and the defective product discharge track 120, respectively. The feeding direction of the feeding track 110 is opposite to the unloading direction of the defective product discharge track 120 and the good product discharge track 130.

[0023] In this embodiment, the feeding track 110, the defective product discharge track 120, the good product discharge track 130, and the buffer track 140 are arranged sequentially from left to right. Two defective product discharge tracks 120 are provided, allowing for sorting and unloading according to defect type. In other embodiments, the order of the feeding track 110, defective product discharge track 120, good product discharge track 130, and buffer track 140 can be changed. For example, the buffer track 140 can be positioned between the defective product discharge track 120 and the good product discharge track 130 to shorten the transfer route for good and defective products on the buffer track 140.

[0024] The electronic component sorting system also includes a detection mechanism 200, which comprises a first detection module 210 and a second detection module 220. The first detection module 210 is located below one side of the feeding track 110, facing the lower surface of the component to be tested, and is used to detect the lower surface of the component. The second detection module 220 is located above the good product discharge track 130 and the buffer track 140 and can reciprocate between the two conveyor tracks. The second detection module 220 faces the upper surface of the component to be tested and is used to detect the upper surface of the component. The first detection module 210 is a 3D detection module, and the second detection module 220 is a 2D detection module.

[0025] Multiple conveyor tracks 100 are set on the installation platform 300, and the first support frame 310 and the second support frame 320 are set at intervals along the second direction B on the installation platform 300 and span the multiple conveyor tracks 100.

[0026] The first support frame 310 is slidably equipped with a picking mechanism 400 and a sorting mechanism 500. The lower part of the first support frame 310 is divided into a picking area 410 and a sorting area 510.

[0027] The pickup area 410 is the area covered by the first detection module 210 and the area adjacent to the feeding track 110 and the first detection module 210. The pickup mechanism 400 is used to pick up multiple components to be tested and move them back and forth between the first detection module 210 and the feeding track 110 (i.e., the pickup area 410). The pickup mechanism 400 picks up multiple components to be tested from the tray of the feeding track 110 at one time, transfers them to the top of the first detection module 210, detects and records the detection results, and then puts the multiple components to be tested back to their original positions.

[0028] Two pickup mechanisms 400 are provided, located on both sides of the first support frame 310 respectively. The two pickup mechanisms 400 can work alternately to improve detection efficiency. The first detection module 210 is slidably mounted on the lower surface of the mounting platform 300. The pickup area 410 of the mounting platform 300 is provided with an opening 330. The first detection module 210 is driven to move along the second direction B, switching to the position below the two pickup mechanisms 400 to detect the component under test.

[0029] The sorting area 510 is located below the first support frame 310 and spans the defective product discharge track 120, the good product discharge track 130, and the buffer track 140. The sorting mechanism 500 is used to remove defective products from the good product discharge track 130 and the buffer track 140 to the defective product discharge track 120, and to pick up good products from the buffer track 140 to replenish the good product discharge track 130. The sorting mechanism 500 picks up defective products from the trays of the good product discharge track 130 to the trays of the defective product discharge track 120, picks up defective products from the trays of the buffer track 140 to the trays of the defective product discharge track 120, and picks up good products from the trays of the buffer track 140 to the trays of the good product discharge track 130, until the trays of the good product discharge track 130 are full and the trays of the defective product discharge track 120 are full and the products are discharged.

[0030] A material tray conveying mechanism 600 and a second detection module 220 are slidably mounted on the second support frame 320, respectively located on both sides of the second support frame 320. The lower part of the second support frame 320 is divided into a conveying area 610 and a detection area 230.

[0031] The electronic component sorting system also includes an empty material tray stacking mechanism 700, which is located on one side of the feeding track 110. The material tray conveying mechanism 600 carries the empty material tray from the empty material tray stacking mechanism 700 to the defective product discharge track 120.

[0032] The transport area 610 is the area covered by the pallet transport mechanism 600, which moves along the first direction A and spans multiple conveyor tracks 100 and the empty pallet stacking mechanism 700. The pallet transport mechanism 600 is used to transport pallets between the multiple conveyor tracks 100. The pallet transport mechanism 600 transports pallets from the loading track 110 to the good product discharge track 130 and the buffer track 140; and transports empty pallets from the empty pallet stacking mechanism 700 or the buffer track 140 to the defective product discharge track 120.

[0033] The detection area 230 is the area covered by the second detection module 220 moving along the first direction A and spanning the good product discharge track 130 and the buffer track 140. The second detection module 220 is used to detect the upper surface of the component to be tested in the loading tray of the good product discharge track 130 and the buffer track 140.

[0034] The multiple conveyor tracks 100 have roughly the same structure. Each conveyor track 100 has a lifting mechanism at its first end 150 for storing trays, and each conveyor track 100 has at least one transfer slider for conveying trays. After the trays in the buffer track 140 are emptied, the empty trays can be conveyed to the lifting mechanism of the buffer track 140 for storage, or the empty trays can be conveyed to the second end of the buffer track 140, where the tray handling mechanism 600 will transport the empty trays to the defective product discharge track 120.

[0035] The feeding track 110 is equipped with two transfer sliders, which move between the first end 150 and the pickup area 410, and between the pickup area 410 and the second end 160, respectively. The two transfer sliders allow the second tray to be transferred to the pickup area 410 simultaneously as the first tray is detected and transferred to the second end 160, thus improving transfer efficiency. Other conveyor tracks 100 can also be equipped with two transfer sliders to improve transfer efficiency.

[0036] The sorting area 510 of the buffer track 140 can also be optionally equipped with a lifting mechanism. After the material is unloaded from the tray of the defective product discharge track 120, the lifting mechanism of the sorting area 510 of the buffer track 140 lifts the tray of the sorting area 510. The buffer track 140 conveys the empty tray at the first end 150 to the second end 160, providing an empty tray for the defective product discharge track 120.

[0037] The setting of buffer track 140 optimizes the track layout and sorting logic, reduces unnecessary handling, and improves the sorting efficiency of electronic components.

[0038] like Figure 2 As shown, the pickup mechanism 400 includes a mounting frame 420, an adsorption module 430, and a pressing module 440, with the adsorption module 430 being pressed against the mounting frame 420 by the pressing module 440.

[0039] like Figure 3 , Figure 4As shown, the adsorption module 430 includes a mounting plate 431 and multiple suction nozzles 432. The suction nozzles 432 are elastically mounted on the mounting plate 431. The mounting plate 431 has multiple air passages inside, and first air ports 4311 and second air ports 4312 are formed on its upper and side surfaces, respectively. The suction nozzles 432 are connected to the first air ports 4311. The mounting bracket 420 has multiple air nozzles 421 connected to the second air ports 4312. In this embodiment, the number of suction nozzles 432 is set to 14, based on the number of test elements in each row of the material tray. The number of air passages is also set to 14, corresponding to the number of suction nozzles 432. The adsorption module 430 can be quickly installed and disassembled via the clamping module 440, and can be quickly connected to the air nozzles 421 via the second air ports 4312, facilitating rapid replacement of the adsorption module 430.

[0040] The mounting plate 431 has protruding mounting portions 4313 on its left and right sides for mounting on the mounting bracket 420.

[0041] like Figure 4 As shown, the mounting bracket 420 includes two L-shaped supports 422 and a nozzle holder 423. The two L-shaped supports 422 are mounted on both sides of the sliding plate 450, and the nozzle holder 423 is mounted between the two L-shaped supports 422. Multiple nozzles 421 are mounted on the nozzle holder 423. Multiple air passages are provided inside the nozzle holder 423. Air pipe connectors 424 are connected to the mounting surfaces of the nozzle holder 423 (different from the nozzles 421) of the multiple air passages. The air pipe connectors 424 are connected to a vacuum device. There are 14 nozzles 421, which are connected to the second air port 4312 of the adsorption module 430. The nozzle holder 423 and the adsorption module 430 can be replaced synchronously, allowing for the replacement of the nozzle holder 423 and adsorption module 430 with different numbers of nozzles 421 and suction nozzles 432. A receiving portion 425 is formed between the two L-shaped supports 422 to accommodate the adsorption module 430. The adsorption module 430 is mounted on the upper surface of the horizontal section of the L-shaped bracket 422 via the mounting part 4313 and is pressed by the pressing module 440.

[0042] Two clamping modules 440 are provided, each mounted on an L-shaped bracket 422. Each clamping module 440 includes a clamping mounting plate 441 and a pressing roller 442. The clamping mounting plate 441 is vertically mounted on the side surface of the L-shaped bracket 422. The pressing roller 442 is mounted on the end of a pressing arm 443. The clamping mounting plate 441 has a slotted hole 4411 extending through the plate body. The pressing arm 443 is rotatably mounted on the clamping mounting plate 441 via screws 444 and the slotted hole 4411. A fixing block 445 is provided on the upper surface of the clamping mounting plate 441, and a through hole 4412 communicating with the slotted hole 4411 is machined inward on the upper surface of the clamping mounting plate 441. A first pressing member 446 is provided within the through hole 4412, with one end of the first pressing member 446 pressing against the screw 444 and the other end pressing against the fixing block 445. The first pressing member 446 is preferably a spring, and under the action of the first pressing member 446, the pressing wheel 442 can always press against the upper surface of the mounting plate 441.

[0043] A second pressing member 447 is also provided on the side wall of the clamping mounting plate 441 facing the clamping module 440, for pressing against the side surface of the adsorption module 430. The second pressing member 447 is preferably a ball-head plunger. The pressing wheel 442, the second pressing member 447, and the L-shaped bracket 422 fix the adsorption module 430 from the four surfaces of the mounting plate 431, which facilitates the disassembly and installation of the adsorption module 430.

[0044] The upper surface of the horizontal section of the L-shaped bracket 422 is provided with a groove 4221, forming two stepped surfaces that restrict the front and rear surfaces of the mounting plate 431.

[0045] The sliding plate 450 is connected to a driving component 460, which is preferably a combination of a motor and a lead screw, to drive the sliding plate 450 to move up and down, thereby driving the adsorption module 430 to move up and down.

[0046] Refer again Figure 1 As shown, the working process of this embodiment is as follows: The first end of the feeding track 110 has multiple layers of full trays containing components to be tested. The lifting mechanism of the feeding track releases the first tray to the transfer slider of the feeding track 110. The transfer slider conveys the tray to the pickup area 410. Two pickup mechanisms 400 alternately pick up the entire row of components to be tested. The pickup mechanism 400 is driven to the top of the first detection module 210. The first detection module 210 is driven to move along the second direction B, alternately corresponding to the two pickup mechanisms 400 to detect the components to be tested.

[0047] After the test components in the tray are tested, another transfer slider of the loading track 110 transfers the first tray to the second end 160 of the loading track 110. At the same time, another transfer slider transfers the second tray to the pickup area 410.

[0048] The tray conveying mechanism 600 moves in the conveying area 610, transporting the first tray from the second end 160 of the loading track 110 to the second end 160 of the good product discharge track 130. The good product discharge track 130 conveys the first tray to the inspection area 230, where the second inspection module 220 inspects the upper surface of the component to be tested in the first tray. After inspection, the good product discharge track 130 conveys the first tray to the sorting area 510.

[0049] The pallet handling mechanism 600 picks up an empty pallet from the empty pallet stacking mechanism 700 or the second end 160 of the buffer track 140 and transfers it to the defective product discharge track 120. The defective product discharge track 120 then conveys the empty pallet to the sorting area 510.

[0050] After the components to be tested in the second tray are tested by the first detection module 210, the second tray is conveyed to the second end 160 of the loading track 110. The tray transport mechanism 600 then transports the second tray to the second end 160 of the buffer track 140. The buffer track 140 conveys the second tray to the detection area 230, and the second detection module 220 moves above the buffer track 140 to test the upper surface of the components to be tested in the second tray. After the test is completed, the buffer track 140 conveys the second tray to the sorting area 510.

[0051] The sorting mechanism 500 picks up defective products from the first tray and transfers them to the trays on the defective product discharge track 120, creating vacancies in the first tray due to the removal of defective products. The sorting mechanism 500 then picks up defective products from the second tray and transfers them to the trays on the defective product discharge track 120. The sorting mechanism 500 then picks up good products from the second tray and transfers them to the empty slots on the good product discharge track 130.

[0052] After the trays of the good product discharge track 130 are replenished with good products, the trays are conveyed to the first end 150 of the good product discharge track 130, and the lifting mechanism lifts and stacks the good product trays.

[0053] After the tray of the defective product discharge track 120 is filled with defective products, the tray is conveyed to the first end 150 of the defective product discharge track 120, and the lifting mechanism lifts and stacks the defective product tray.

[0054] After the material trays of the buffer track 140 are emptied, the empty material trays are conveyed to the first end of the buffer track 140, and the lifting mechanism lifts and stacks the empty material trays.

[0055] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model is defined by the claims.
