Description

Technical Field

[0001] The present invention relates to the technical field of automated equipment, and in particular to a batch loading and unloading device and method for aging equipment. Background Art

[0002] During the chip production process, burn-in testing accelerates the exposure of potential chip defects by simulating extreme conditions such as high temperature and high pressure. This effectively screens for premature failures and predicts service life, thereby improving the reliability of chips used in key sectors such as automotive and medical applications. However, the loading and unloading processes of current burn-in equipment still rely on traditional manual or semi-automated operations, resulting in low chip positioning accuracy and time-consuming fixture switching.

Figure 12 This is a schematic structural diagram of the replacement mechanism 620 of the batch loading and unloading device of the aging equipment provided in this embodiment.

[0083] The batch loading and unloading device for aging equipment provided in this embodiment has the following beneficial effects:

[0084] 1. This invention realizes the full process closed-loop operation of automatic loading and unloading, opening and closing of covers, pre-testing and abnormal handling of chips 100 and boards 330 through the tray loading and unloading assembly 200, board loading and unloading assembly 300, cover opening assembly 400, cover closing assembly 500, pre-testing assembly 600 and transplanting assembly 700, realizes the full automation operation of batch loading and unloading of aging equipment, and improves the efficiency of batch loading and unloading of aging equipment;

[0085] 2. The pre-test component 600 can promptly detect faults in the chip 100 or the tooling 331 on the board 330, and can confirm that the abnormality is specifically in the chip 100 or the tooling 331 by replacing the structure, and promptly process the abnormal chip 100 or tooling 331 to avoid aging testing of the abnormal chip 100 or tooling 331, thereby improving the efficiency of the aging test.

[0086] In some embodiments, as Figure 4 and Figure 5 As shown, the tray loading and unloading assembly 200 includes:

[0087] The silo assembly includes an upper silo 211, a lower silo 212, and an abnormal sorting silo 213, which are used to store the upper tray 221, the lower tray 222, and the abnormal tray 223 respectively;

[0088] The depalletizing and palletizing mechanism 230 is used to perform depalletizing and palletizing operations on the pallets in the silo assembly, wherein the depalletizing operation removes the loading pallet 221 from the loading silo 211, and the palletizing operation is used to store the unloading pallet 222 and the abnormal pallet 223 in the unloading silo 212 and the abnormal sorting silo 213 respectively;

[0089] The transplanting assembly 700 includes a pallet transplanting mechanism 710, which is used to receive the loading pallet 221 from the depalletizing and stacking mechanism 230 and transplant it to the loading station, and to transplant the unloading pallet 222 and the abnormal pallet 223 from the unloading station to the depalletizing and stacking mechanism 230 at the unloading bin 212 and the abnormal sorting bin 213 respectively.

[0090] Among them, multiple loading bins 211, unloading bins 212 and abnormal sorting bins 213 can be provided to facilitate temporary storage of pallets and reduce the demand for pallet transportation.

[0091] Among them, the loading bin 211, the unloading bin 212 and the abnormal sorting bin 213 can be arranged along a straight line, and the tray transfer mechanism 710 can adopt a linear moving module, such as Figure 4 and 5 As shown, the pallet can be transplanted by moving in a straight line. The loading station and the unloading station can also be set at a position between the loading bin 211, the unloading bin 212 and the abnormal sorting bin 213, such as Figure 4 and 5 As shown, multiple loading bins 211 and unloading bins 212 are arranged adjacent to each other, and are discontinuously arranged with the abnormal sorting bin 213, with empty spaces formed between them to serve as loading stations and unloading stations. This structural arrangement also facilitates the storage of incoming material pallets into the equipment and the removal of unloading pallets 222 from the equipment, and the equipment can be equipped with more centralized loading and unloading windows.

[0092] Each loading bin 211, unloading bin 212, and abnormal sorting bin 213 may be provided with a depalletizing and stacking mechanism 230, or the depalletizing and stacking mechanism 230 may also be provided as a movable mechanism. The depalletizing and stacking mechanism 230 for pallets is conventional technology, and this application does not limit the specific structure of the depalletizing and stacking mechanism 230.

[0093] In some embodiments, as Figure 6 and Figure 7 The board loading and unloading assembly 300 includes:

[0094] Multi-layer board material bin 310, each layer of board material bin 310 is used to store at least one board 330;

[0095] The lifting mechanism 320 is used to adjust the height of the multi-layer board hopper 310;

[0096] The detection sensor monitors the empty or full status of each layer of the board material bin 310 in real time.

[0097] The multi-layer board hopper 310 can improve equipment space utilization. After the detection sensor detects the empty or full state of the board hopper 310, the lifting mechanism 320 can lift the board hopper 310 according to the empty or full state. When the board loading and unloading assembly 300 needs to receive boards 330, such as when boards 330 need to be stored after pre-testing or after aging testing, the empty board hopper 310 is moved to the receiving position. When the board loading and unloading assembly 300 needs to provide boards 330, such as when boards 330 are removed from the board loading and unloading assembly 300 for aging testing or when the cover opening assembly 400 needs to remove boards 330 for opening the cover, the full board hopper 310 is moved to the receiving position. The receiving positions can be specifically configured to correspond to different mechanisms, and the lifting mechanism 320 can be adjusted according to the state of the board hopper 310.

[0098] In some embodiments, as Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, the cover opening assembly 400 includes an X-axis moving module 410, a Z-axis lifting module 420 and a plate pulling finger 430. The plate pulling finger 430 is used to connect with the board 330, and the X-axis moving module 410 and the Z-axis lifting module 420 are used to drive the plate pulling finger 430.

[0099] in, Figure 8 This is a three-dimensional schematic diagram of the cover opening assembly 400 of the batch loading and unloading device for aging equipment provided in this embodiment. Figure 9 This is a schematic diagram of the partial structure of the cover opening assembly 400 of the batch loading and unloading device of the aging equipment provided in this embodiment.

[0100] like Figure 1 As shown, the cover opening assembly 400 and the board loading and unloading assembly 300 are arranged adjacent to each other, and the direction of the adjacent arrangement is defined as the X-axis. The X-axis moving module 410 is used to drive the plate pulling fingers 430 to move into the board loading and unloading assembly 300, and the Z-axis lifting module 420 can drive the plate pulling fingers 430 to move up and down. For example, before the plate pulling fingers 430 move to the board loading and unloading assembly 300, the plate pulling fingers 430 are in a higher position. After the plate pulling fingers 430 move to the board loading and unloading assembly 300, the Z-axis lifting module 420 drives the plate pulling fingers 430 to descend, and the plate pulling fingers 430 engage with the board 330. Thereafter, the X-axis moving module 410 drives the plate pulling fingers 430 back to their original position, thereby completing the operation of removing the board 330 from the board loading and unloading assembly 300. The action logic of the cover opening component 400 to remove the board 330 is not limited to this. According to the specific structure of the board 330 and the specific structure of the board pulling finger 430, a variety of matching modes and operation modes can be flexibly set, and the present invention does not limit this.

[0101] In some embodiments, as Figure 6 、 Figure 8 and Figure 9 As shown, the box cover of the tooling 331 includes a pull rod 332, and the cover opening assembly 400 includes: an X-axis moving module 410, used to drive the Z-axis lifting module 420 to move horizontally; the Z-axis lifting module 420, used to drive the cover opening finger 440 to lift vertically; the cover opening finger 440, including a closed state and an open state, the cover opening finger 440 can clamp the pull rod 332 in the closed state, the Z-axis lifting module 420 drives the cover opening finger 440 to move upward, the cover opening finger 440 drives the pull rod 332 to open the box cover, and the cover opening finger 440 is separated from the pull rod 332 in the open state.

[0102] On the board 330, the chip 100 is placed in the tooling 331, and the cover of the tooling 331 is used to protect the chip 100. When the board 330 is located in the board loading and unloading assembly 300, the cover is in a closed state. The lid-opening finger 440 can open the box lid by cooperating with the pull rod 332 of the box lid. The specific operation logic is as follows: the X-axis moving module 410 drives the Z-axis lifting module 420 to move horizontally until the lid-opening finger 440 is vertically aligned with the pull rod 332. During the movement, the Z-axis lifting module 420 places the lid-opening finger 440 in a relatively high position. After alignment, the Z-axis lifting module 420 lowers the lid-opening finger 440 until the lid-opening finger 440 is horizontally aligned with the pull rod 332. Then, the lid-opening finger 440 closes to clamp the pull rod 332. Then, the Z-axis lifting module 420 drives the lid-opening finger 440 to move upward. The lid-opening finger 440 drives the pull rod 332 to open the box lid. During this process, the X-axis moving module 410 can also move synchronously to achieve compound movement. After the box lid is fully opened, the lid-opening finger 440 opens, and the X-axis moving module 410 and the Z-axis lifting module 420 drive the lid-opening finger 440 to move away.

[0103] like Figure 9 As shown, the opening fingers 440 can be arranged in pairs. The opening fingers 440 arranged in pairs move toward each other to achieve a closed state and move away from each other to achieve an open state. The movement of the opening fingers 440 can be driven by a cylinder or a servo motor.

[0104] In the cover opening assembly 400, a plurality of cover opening fingers 440 can be provided to realize batch opening. Figure 6 As shown, the tooling 331 on the board 330 can be arranged in multiple rows and columns. After multiple opening fingers 440 are provided, the opening of the box covers of one row or one column can be processed at one time, thereby improving the operation efficiency.

[0105] In some embodiments, as Figure 6 and Figure 10As shown, the box cover of the tooling 331 includes a pull rod 332, and the cover closing assembly 500 includes: an X-axis displacement module, configured to drive the Z-axis pressing module to move horizontally; and the Z-axis pressing module, configured to drive the cover closing finger 510 to press down vertically to close the box cover.

[0106] wherein, Figure 10 A perspective view of a cover closing assembly 500 of a batch feeding and discharging device of an aging equipment is provided in the embodiment. As shown, Figure 10 The lower end of the cover closing finger 510 can be further provided with a roller or the like, so that the cover closing finger 510 and the box cover are in rolling contact, reducing damage to the box cover. As shown, Figure 10 The cover closing assembly 500 can be further provided with an opening cover finger 440. The opening cover finger 440 can cooperate with the pull rod 332 to further increase the effect of the box cover after the box cover is closed through the pull rod 332, while reducing damage to the box cover. The opening cover finger 440 moves through the X-axis displacement module and the Z-axis pressing module. The opening and closing operations of the opening cover finger 440 can be similar to the above embodiments.

[0107] In some embodiments, as shown in Figure 11 and 12 The pre-test mechanism 610 includes a pre-test machine 611 including a port for connecting with the board card 330, and a crimping module 612 for crimping the port of the board card 330 with the port of the pre-test machine 611. The crimping module 612 can fix the board card 330, so as to ensure that the port of the board card 330 is crimped with the port of the pre-test machine 611. The crimping module 612 can include a linear movement mechanism, such as a linear servo motor, so as to drive the board card 330 to connect with the pre-test machine 611.

[0108] In some embodiments, as shown in Figure 11 and 12 The box cover of the tooling 331 includes a pull rod 332, and the exchange mechanism 620 includes: an opening cover finger 440, including a closed state and an open state, the opening cover finger 440 can clamp the pull rod 332 in the closed state, and the opening cover finger 440 is separated from the pull rod 332 in the open state; a suction nozzle 621, which can be used to suck and release the chip 100 in the tooling 331; and a three-axis movement module 613, configured to drive the opening cover finger 440 and the suction nozzle 621 to move. The opening cover finger 440 can be provided in pairs, and the opening and closing operations of the opening cover finger 440 can be similar to the above embodiments. The suction nozzle 621 can be provided with an additional Z-axis movement distance, as shown in Figure 12As shown, the suction nozzle 621 does not interfere with the box cover during the operation of the cover opening finger 440. After the cover is opened, the suction nozzle 621 moves downward a longer distance to exceed the lower end of the cover opening finger 440, thereby sucking the chip 100 in the tooling 331. The suction nozzle 621 and cover opening finger 440 can be provided in two groups, and the cover opening and chip 100 sucking operations can be performed on two toolings 331 simultaneously, thereby improving operational efficiency. The exchange mechanism 620 can also be provided with a cover pushing finger 510. The structure and control method of the cover pushing finger 510 can be similar to those of the above embodiment.

[0109] In some embodiments, as Figure 13 and 14 As shown, the transfer assembly 700 includes: a board transfer mechanism 720, which is used to transfer the board 330 between the tray loading and unloading assembly 200, the cover opening assembly 400, the cover closing assembly 500, the pre-test assembly 600 and the board loading and unloading assembly 300; and a chip transfer mechanism 730, which is used to transfer the chip 100 between the tray and the tooling 331.

[0110] in, Figure 13 This is a schematic diagram of the structure of the chip transfer mechanism 730 of the batch loading and unloading device of the aging equipment provided in this embodiment. Figure 14 This is a structural diagram of the board transfer mechanism 720 of the batch loading and unloading device for the aging equipment provided in this embodiment.

[0111] Specifically, after the cover opening assembly 400 opens the board 330, the board transfer mechanism 720 can remove the board 330 from the cover opening assembly 400 and transfer it to the loading station, and the chip transfer mechanism 730 transfers the chip 100 from the tray to the board 330 at the loading station. Figure 13 As shown, the chip transfer mechanism 730 can be equipped with multiple suction nozzles 621 to simultaneously pick up multiple chips 100. The chip transfer mechanism 730 can also be equipped with a pitch-changing mechanism to change the spacing between the multiple chips 100, thereby adapting to different arrangements of the chips 100 on the tray and the board 330. The pitch-changing mechanism can be in the form of a multi-stage cylinder, a multi-stage motor, or a pitch-changing guide groove, etc., and the pitch-changing effect is achieved by adjusting the positions of the multiple suction nozzles 621.

[0112] A batch loading and unloading method for aging equipment

[0113] This embodiment provides a batch loading and unloading method for aging equipment, which uses the batch loading and unloading device for aging equipment as described in any of the above embodiments, including the following steps:

[0114] Using the transfer assembly 700, tray loading and unloading assembly 200, board loading and unloading assembly 300, cover opening assembly 400, and cover closing assembly 500, the chip 100 to be tested is transferred from the loading tray 221 to the tooling 331 of the board 330. After closing the box cover, the board 330 is transferred to the pre-test assembly 600.

[0115] The pre-test mechanism 610 performs a first round of pre-test on the board 330. If a pre-test abnormality is detected, the replacement mechanism 620 opens the cover of the tooling 331 with the abnormal pre-test and the adjacent tooling 331 with normal pre-test on the aged board 330, replaces the chip 100, and closes the cover to perform a second round of pre-test. If the same tooling 331 is abnormal in both the first and second rounds of pre-test, the corresponding tooling 331 is evaluated as abnormal and shielded. If the same chip 100 is abnormal in both the first and second rounds of pre-test, the corresponding chip 100 is evaluated as abnormal, and the transfer mechanism transfers the chip 100 evaluated as abnormal to the abnormal tray 223.

[0116] The transfer mechanism transfers the pre-tested board 330 from the pre-test assembly 600 to the board loading and unloading assembly 300;

[0117] Taking out the board 330 from the board loading and unloading assembly 300 to perform an aging test, and returning the board 330 after the aging test to the board loading and unloading assembly 300;

[0118] The chips 100 in the board 330 that have completed the aging test are transferred to the unloading tray 222 in the tray unloading assembly 200 using the transfer assembly 700 , the tray unloading assembly 200 , the board unloading assembly 300 , the cover opening assembly 400 and the cover closing assembly 500 .

[0119] The batch loading and unloading method for aging equipment provided in this embodiment has the following beneficial effects:

[0120] 1. The present invention can automatically transfer the chip 100 from the tray to the board 330, and then perform pre-testing, promptly handle abnormal chips 100 or tooling 331, and then automatically send them to the board loading and unloading assembly 300 for the next step of aging test. After the aging test is completed, the chip 100 can also be automatically moved from the board 330 to the tray to facilitate subsequent production links.

[0121] 2. When using the pre-test component 600 for pre-testing, not only can the abnormality of the specific tooling 331 on the board 330 be discovered, but the chip 100 in the abnormal tooling 331 and its adjacent tooling 331 can also be replaced through the replacement mechanism 620, thereby confirming that the chip 100 or the tooling 331 is abnormal, so that the chip 100 can be sorted out or the tooling 331 can be shielded in time, thereby improving the efficiency of the aging test.

[0122] This method involves multiple components, which can operate synchronously without causing interference to improve operational efficiency.

[0123] During the pre-test, if the second round of interpretation results show no abnormalities, it is determined that an error such as placement deviation occurred during the first round of testing, and there is no need to determine that the chip 100 and the tool 331 are abnormal. If both toolings 331 are abnormal during the second round of testing, both toolings 331 and the chip 100 can be determined to be abnormal, both toolings 331 can be blocked, and the abnormal chip 100 can be moved to the abnormal tray 223.

[0124] The specific operation of transferring the abnormal chip 100 to the abnormal tray 223 may be that the board transfer mechanism 720 transfers the board 330 from the pre-test mechanism 610 to the loading and unloading station, and the chip transfer mechanism 730 transfers the chip 100 to the abnormal tray 223 at the loading and unloading station.

[0125] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
