Description

Technical Field

[0001] This invention belongs to the field of material testing and sorting technology, and more specifically, relates to a tray feeding mechanism, testing equipment and testing method for preventing material from being left in a tray. Background Technology

[0002] Integrated circuit testing mainly involves testing various digital, analog, and mixed-signal integrated circuits. The test results determine whether the tested devices are qualified and can also provide information on manufacturing process and design issues. Therefore, the accuracy of integrated circuit testing plays a crucial role. Chip Final Test (FT) refers to the functional verification and electrical parameter testing of the finished product after chip packaging. FT testing equipment mainly consists of two parts: a tester and a sorter. The sorter physically classifies the chips according to different performance characteristics or good / bad results.

[0003] like Figure 1 As shown, the existing sorting machine's workflow is as follows: a tray containing the material to be tested is conveyed to a position near the testing machine 9 via the infeed conveyor line 1. The suction head of the robotic arm 3 picks up the material from the tray and transfers it to the testing machine 9 for testing and sorting. After the material on the tray is picked up and moved by the robotic arm 3, the suction cup mechanism places the tray at the outlet conveyor line 11 and pushes it out of the sorting machine. The operator can check whether each tray that has been pushed out has any material left. Trays without material are placed on the infeed conveyor line 10. Empty trays are then conveyed to a position near the testing machine 9, where the suction cup mechanism places the empty trays on the respective outlet conveyor lines 2. After the trays are filled with the tested and sorted material, they are automatically conveyed to the material pick-up position via the outlet conveyor line 2.

[0004] If a tray containing residual material is used to load and test sorted materials, it will cause mixing. Once mixed, the mixed materials cannot be traced, and the entire batch needs to be retested and screened. This situation poses a significant quality risk and reduces production efficiency. To avoid this, the sorting machine automatically removes the trays from the sorting machine via an outgoing conveyor. Operators check that the trays are empty before placing them into the next position near the testing machine for reuse. Since the amount of material that a single tray can hold is limited, the larger the material, the fewer materials the trays can hold, and the more trays are needed. Therefore, operators need to frequently and extensively check the trays and put them into the outgoing conveyor. Based on a 1 / 5 human-machine ratio (6.5mm x 8.6mm products / UPH 2000), the number of tray checks required per day is approximately 1000, greatly increasing the workload of operators. At the same time, the repeated tray loading and unloading operations of the entire equipment also increase the overall idle time of the equipment, reducing the overall production efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a tray feeding mechanism, testing equipment, and testing method for preventing material residue in the tray. This addresses the problems mentioned in the background art, where the trays of existing sorting machines need to be pushed out of the sorting machine after unloading for operators to check for any remaining material. This requires operators to spend a significant amount of time each shift checking the pushed-out trays, increasing their workload. Furthermore, the sorting machine needs to convey the trays out for inspection before conveying them to the testing position, increasing the idle running time of the testing equipment and affecting the equipment's production efficiency.

[0006] To achieve the above objectives, the present invention provides a tray feeding mechanism for preventing material residue in a sorting machine, which is disposed above the feed conveyor line and multiple discharge conveyor lines of the sorting machine. The tray feeding mechanism includes:

[0007] A spatial conveying module is disposed above the infeed conveyor line and the plurality of outfeed conveyor lines;

[0008] A flipping mechanism is connected to the space transport module, and the space transport module can drive the flipping mechanism to move laterally or vertically.

[0009] A clamping mechanism is connected to the flipping part of the flipping mechanism. The clamping mechanism is used to clamp the tray, and the flipping mechanism is used to flip the tray so that the material to be tested remaining in the tray is removed from the tray.

[0010] Preferably, the tray feeding mechanism of the sorting machine for preventing material from being left behind further includes a striking mechanism. The striking mechanism is connected to the clamping mechanism. The striking mechanism is used to strike the tray containing material to be tested. The striking mechanism includes a striking drive and a striking block. The striking block is connected to the striking end of the striking drive.

[0011] Preferably, the space transport module includes:

[0012] Lateral linear module;

[0013] A vertical linear module is connected to the lateral moving part of the horizontal linear module, and a flipping mechanism is connected to the vertical moving part of the vertical linear module.

[0014] Preferably, the clamping mechanism includes:

[0015] Telescopic drive component;

[0016] Two grippers, which are respectively connected to the two telescopic ends of the telescopic drive member.

[0017] Preferably, the material feeding mechanism of the sorting machine for preventing material from being left behind further includes a collection tray, which is disposed below the feed conveyor line and the plurality of discharge conveyor lines.

[0018] A testing device comprising:

[0019] The sorting machine includes an infeed conveyor line, at least one outfeed conveyor line, and a tray feeding mechanism to prevent material from being left behind. The tray feeding mechanism is located above the infeed conveyor line and at least one outfeed conveyor line.

[0020] A testing machine, wherein the testing machine is positioned close to the sorting machine;

[0021] At least one robotic arm is provided, positioned near the sorting machine and the testing machine. The robotic arm is capable of moving the material to be tested from the tray on the feed conveyor line into the testing machine, or moving the tested material in the testing machine into the trays on multiple discharge conveyor lines according to the quality.

[0022] The control unit can set the quantity of material to be tested that the tray on the feeding conveyor line can carry. The control unit can detect the quantity of material to be tested picked up by the robot arm. When the robot arm picks up or puts down the material to be tested and an alarm is triggered, the control unit can control the flipping mechanism to flip the tray.

[0023] The control unit is equipped with a logic judgment program, which can compare the quantity of materials to be tested picked up by the robot arm from the material tray with the quantity of materials to be tested carried by the material tray on the feeding conveyor line. The control unit can control the flipping mechanism to flip the material tray according to the comparison result.

[0024] Preferably, the sorting machine further includes:

[0025] The tray infeed conveyor line and the tray outfeed conveyor line are arranged between the tray infeed conveyor line and the tray outfeed conveyor line.

[0026] Multiple support trays are provided on the discharge conveyor line, the infeed conveyor line, the tray infeed conveyor line, and the tray discharge conveyor line. The support trays are used to carry the material trays.

[0027] A testing method, the method comprising:

[0028] The material tray containing the material to be tested is fed into the testing position via the feeding conveyor line.

[0029] Remove the material to be tested;

[0030] Tested using a testing machine;

[0031] The material tray of the sorting machine is clamped and flipped by the tray feeding mechanism to prevent the material to be tested from remaining in the tray.

[0032] Place the empty tray on the discharge conveyor line.

[0033] Preferably, when the material feeding mechanism of the sorting machine for preventing material residue includes a striking mechanism, and the striking mechanism includes a striking drive and a striking block, and the striking block is connected to the striking end of the striking drive, the method further includes:

[0034] A tapping mechanism is used to tap the tray to prevent any remaining material to be tested from remaining in the tray.

[0036] When the control unit receives an alarm signal from the robotic arm picking up or putting down the material to be tested, it flips the feeding mechanism of the clamping tray.

[0037] The logic judgment program compares the number of materials to be tested picked up by the robot arm from the material tray with the number of materials to be tested carried on the material tray on the feeding conveyor line. Based on the comparison result, the feeding mechanism holding the material tray is controlled to flip.

[0038] This invention provides a tray feeding mechanism, testing equipment, and testing method for preventing material residue on a tray. Its advantages are as follows: the tray feeding mechanism's flipping mechanism is connected to a spatial conveying module, and the clamping mechanism is connected to the flipping part of the flipping mechanism. When the material on the tray on the infeed conveyor line is unloaded by a robotic arm, the tray is flipped by the flipping mechanism, allowing any remaining material on the tray to fall off naturally. The spatial conveying module can then directly move the tray to one of the discharge conveyor lines, where the tested material can be loaded onto the tray. This reduces manual operation and the time required for tray loading and unloading, lowering the labor intensity of operators and improving work efficiency.

[0039] The control unit of this testing equipment is equipped with a logic judgment program that can automatically calculate and compare the quantity of materials to be tested picked up from the tray by the robotic arm with the quantity of materials to be tested carried by the tray on the feeding conveyor line. It determines whether there is any residual material in the tray held by the clamping mechanism. If there is residual material, the flipping mechanism flips the tray, and the residual material on the tray can fall off naturally. If there is no residual material in the tray, the spatial conveying module can directly move the tray to one of the discharge conveyor lines, further improving work efficiency and reducing the labor intensity of operators.

[0051] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0052] like Figure 3 As shown, the present invention provides a tray feeding mechanism for preventing material residue in a sorting machine, which is installed above the feed conveyor line 1 and multiple discharge conveyor lines 2 of the sorting machine. The tray feeding mechanism includes:

[0053] Space conveying module 4 is positioned above the infeed conveyor line 1 and multiple outfeed conveyor lines 2.

[0054] The flipping mechanism 5 is connected to the space transmission module 4, which can drive the flipping mechanism 5 to move laterally or vertically.

[0055] The clamping mechanism 6 is connected to the flipping part of the flipping mechanism 5. The clamping mechanism 6 is used to clamp the material tray, and the flipping mechanism 5 is used to flip the material tray so that the material to be tested remaining in the material tray is removed from the material tray.

[0056] Specifically, to address the issue that existing sorting machines require operators to inspect the trays after unloading for any remaining material, which consumes significant time per shift, increasing workload, and the need for the sorting machine to convey the trays for inspection before transferring them to the testing position, thus increasing idle time, the present invention provides a tray feeding mechanism to prevent material residue from remaining in the sorting machine's trays. This mechanism is positioned above the sorting machine's infeed conveyor line 1 and multiple outfeed conveyor lines 2. The tray carrying the material to be tested is conveyed to the testing position via the infeed conveyor line 1, and the material is unloaded by a robotic arm 3 for testing and sorting. The tray can then move the unloaded tray from the infeed conveyor line 1 to one of the outfeed conveyor lines 2. The tray on the outfeed conveyor line 2 is used to load the tested material and can be conveyed to the material pick-up position.

[0057] The flipping mechanism 5 of the feeding mechanism is connected to the spatial conveying module 4, and the clamping mechanism 6 is connected to the flipping part of the flipping mechanism 5. When the material in the tray on the feeding conveyor line 1 is unloaded by the robot arm 3, the tray with unloaded material is clamped by the clamping mechanism 6, and the tray is flipped by the flipping mechanism 5. The material left on the tray can fall off naturally. The spatial conveying module 4 can move the tray directly to one of the discharging conveyor lines 2. At this time, the tested material can be loaded onto the tray, reducing manual operation and the time for tray loading and unloading, reducing the labor intensity of operators and improving work efficiency.

[0058] To address the issue that existing suction cup mechanisms use sponge suction cups to pick up and place material trays, creating a vacuum suction that leads to wear and tear on the sponge suction cups after a certain period of use, resulting in indentations and cracks and requiring replacement with new sponge parts, this tray feeding mechanism changes the original method of sponge suction cup adsorption. It adopts a clamping mechanism 6 for clamping and placing the tray, which is used to clamp and fix the material tray, saving on spare parts usage, reducing equipment malfunction alarms, and lowering the actual operating cost of the equipment.

[0059] like Figure 6 As shown, preferably, the tray feeding mechanism of the sorting machine for preventing material from being left behind also includes a striking mechanism 7. The striking mechanism 7 is connected to the clamping mechanism 6. The striking mechanism 7 is used to strike the tray containing material to be tested. The striking mechanism 7 includes a striking drive 71 and a striking block 72. The striking block 72 is connected to the striking end of the striking drive 71.

[0060] Specifically, the striking drive 71 can be a striking cylinder that drives the striking block 72 to extend and retract to strike the material tray. Its main function is to strike the material tray after it is flipped, further ensuring that the material left on the tray falls off. It can be set to strike multiple times continuously to effectively prevent the material left in the tray from falling off and ensure that the material left on the tray falls off.

[0061] like Figure 4 As shown, preferably, the space transport module 4 includes:

[0062] Lateral linear module 41;

[0063] The vertical linear module 42 is connected to the lateral moving part of the horizontal linear module 41, and the flipping mechanism 5 is connected to the vertical moving part of the vertical linear module 42.

[0064] Specifically, the horizontal linear module 41 can be a horizontal linear guide rail, used to move the material tray from the infeed conveyor line to one of the outfeed conveyor lines. The vertical linear module 42 can be a vertical linear guide rail, controlled by a moving cylinder, used to move the flipping mechanism 5 and the clamping mechanism 6 up and down. When in the lower position, it can pick up and put down the material tray. When in the upper position, it can move horizontally to avoid other mechanisms.

[0065] like Figure 5 As shown, preferably, the clamping mechanism 6 includes:

[0066] Telescopic drive component 61;

[0067] Two grippers 62 are respectively connected to the two telescopic ends of the telescopic drive member 61.

[0068] Specifically, the telescopic drive mechanism 61 can be a telescopic cylinder with two telescopic ends, used to switch and adjust the position of the gripper for laterally fastening the material tray. The gripper 62 can be a pneumatic gripper, which opens and closes by pressing air, so that the gripper 62 can fasten the material tray. The original method of the sponge suction cup of the suction cup mechanism to pick up the material tray is changed to the method of the pneumatic gripper of the clamping mechanism 6 to clamp and fix the material tray, thus solving the problem of the use of sponge suction cup consumables.

[0069] Preferably, the gripper 62 is connected to the telescopic end of the telescopic drive member 61 via a gripper bracket.

[0070] Specifically, the telescopic end of the telescopic drive component 61 is connected to the gripper 62.

[0071] Preferably, the material feeding mechanism of the sorting machine to prevent material from being left behind also includes a collection tray 8, which is located below the feed conveyor line 1 and multiple discharge conveyor lines 2.

[0072] Specifically, a collection tray 8 is added to collect and retain fallen materials so that subsequent operators can collect and process them in a unified manner.

[0073] Preferably, the flipping mechanism 5 includes a rotary motor 51, and the flipping part is the rotating end of the rotary motor 51.

[0074] Specifically, the rotary motor 51 can be a servo motor. Adding the rotary motor 51 allows the material tray to rotate, and it can rotate according to different positions, so that the remaining material can fall off naturally.

[0075] A testing device comprising:

[0076] The sorting machine includes a feed conveyor line 1, at least one discharge conveyor line 2, and a tray feeding mechanism to prevent material from being left behind. The tray feeding mechanism is located above the feed conveyor line 1 and at least one discharge conveyor line 2.

[0077] Test machine 9 is located near the sorting machine;

[0078] At least one robotic arm 3 is positioned near the sorting machine and the testing machine 9. The robotic arm 3 is capable of moving the material to be tested from the tray on the feed conveyor line 1 into the testing machine 9, or moving the tested material in the testing machine 9 into the trays on multiple discharge conveyor lines 2 according to the quality.

[0079] The control unit can set the quantity of material to be tested that the tray on the feed conveyor line 1 can carry. The control unit can detect the quantity of material to be tested picked up by the robot arm. When the robot arm picks up or puts down the material to be tested and an alarm is triggered, the control unit can control the flipping mechanism 5 to flip the tray.

[0080] The control unit is equipped with a logic judgment program, which can compare the quantity of materials to be tested picked up by the robot arm 3 from the material tray with the quantity of materials to be tested carried on the material tray on the feeding conveyor line 1. The control unit can control the flipping mechanism 5 to flip the material tray according to the comparison result.

[0081] Specifically, to address the issue of quality accidents and reduced production efficiency caused by operators failing to check for materials in a tray and then reusing it, this invention provides a testing device. The control unit of this testing device has a logic judgment program that can automatically calculate and specifically detect trays, determining whether the trays need to be flipped and tapped to prevent material residue. Specifically, it compares the quantity of material to be tested picked up by the robotic arm 3 from the tray with the quantity of material to be tested carried by the tray on the infeed conveyor line 1. It determines whether there is any residual material in the tray held by the clamping mechanism 6. If residual material is found, the flipping mechanism 5 flips and taps the tray, causing the residual material to fall off naturally. If no residual material is found, the spatial conveying module 4 can directly move the tray to one of the outfeed conveyor lines 2, further improving work efficiency, reducing the labor intensity of operators, and preventing material mixing.

[0082] Preferably, the sorting machine further includes:

[0083] The tray infeed conveyor line 10 and the tray outfeed conveyor line 11 are arranged between the tray infeed conveyor line 1 and the tray outfeed conveyor line 2, and the tray infeed conveyor line 10 is arranged between the tray outfeed conveyor line 11 and the tray outfeed conveyor line 2.

[0084] Multiple support trays 12 are provided on the discharge conveyor line 2, the infeed conveyor line 1, the tray infeed conveyor line 10, and the tray discharge conveyor line 11. The support trays are used to carry the material trays.

[0085] like Figure 2 As shown, a testing method includes:

[0086] The material tray containing the material to be tested is fed to the test position via the feeding conveyor line 1.

[0087] Remove the material to be tested;

[0088] Tested using test machine 9;

[0089] The material tray of the sorting machine is clamped and flipped by the tray feeding mechanism to prevent the material to be tested from remaining in the tray.

[0090] Place the empty tray on the discharge conveyor line 2.

[0091] Preferably, when the material feeding mechanism of the sorting machine for preventing material residue includes a striking mechanism 7, and the striking mechanism 7 includes a striking drive 71 and a striking block 72, with the striking block 72 connected to the striking end of the striking drive 71, the method further includes:

[0092] The material tray is tapped using the tapping mechanism 7 to prevent any remaining material to be tested from remaining in the tray.

[0093] Preferably, when the control unit can set the quantity of material to be tested that the tray on the feed conveyor line 1 can hold, the robot arm 3 can move the material to be tested from the tray on the feed conveyor line 1 into the testing machine 9, the control unit can detect the quantity of material to be tested picked up by the robot arm 3, and the control unit is equipped with a logic judgment program, the method further includes:

[0094] When the control unit receives an alarm signal from the robot arm 3 picking up or putting down the material to be tested, it flips the feeding mechanism of the clamping tray.

[0095] The logic judgment program compares the number of materials to be tested picked up from the material tray by the robot arm 3 with the number of materials to be tested carried on the material tray on the feeding conveyor line 1. Based on the comparison result, the feeding mechanism holding the material tray is controlled to flip.

[0096] Preferably, the logic judgment program determines whether there is a possibility of residual material in the material tray. If there is, it performs a rotation and tapping action. Through this action, the residual material is effectively physically separated and then directly transported to the material waiting position of the discharge conveyor line 2.

[0097] This logic judgment program can reduce the dwell time of the clamping mechanism 6 caused by continuous plate feeding and dispensing, and improve the utilization efficiency of the equipment.

[0098] This logical judgment procedure reduces the operator's work process of retrieving, checking, and re-inserting the disk, thus reducing the operator's workload.

[0099] This logical judgment procedure reduces human involvement, avoids omissions in inspections due to human oversight, and mitigates the possibility of reusing leftover materials.

[0100] In summary, as Figure 7 As shown, when using this testing equipment, the specific method includes:

[0101] a. The material is placed into the material tray according to the set quantity, and the material tray is placed on the feeding conveyor line 1;

[0102] b. Set the number of times the robotic arm picks up materials;

[0103] c. Determine whether the quantity of materials taken is consistent with the set quantity;

[0104] d. If consistent judgment is made, whether an alarm is triggered when the suction head of the robotic arm 3 picks up or places materials into the testing machine 9;

[0105] e. If no alarm is triggered and the quantity of material taken is consistent with the set quantity;

[0106] f. The clamping mechanism 6 grabs the empty material tray and places it at the material waiting position of the discharge conveyor line 2;

[0107] g. Robotic arm 3 places the tested material into the material tray;

[0108] h. The discharge conveyor line 2 automatically transports the material tray to the material waiting position;

[0109] i. The tray has been used up;

[0110] j. When determining whether the quantity of material taken is consistent with the set quantity, if they are inconsistent, the clamping mechanism 6 will grab the empty material tray and transfer it to the top of the collection tray 8.

[0111] k. The servo motor rotates 180 degrees;

[0112] 1. Tap block 72 repeatedly;

[0113] m. After the servo motor rotates 180 degrees in the opposite direction, the material tray is placed at the material waiting position on the discharge conveyor line 2, and then the subsequent actions continue to convey the material tray to the material waiting position.

[0114] n. When determining whether an alarm is triggered when the suction head of the robotic arm 3 picks up or puts materials into the testing machine 9, if an alarm is triggered, the clamping mechanism 6 grabs the empty material tray and transfers it to the top of the collection tray 8, and then continues the subsequent action to transfer the material tray to the material waiting position.

[0115] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
