[0017] Compared with the prior art, the utility model has the following beneficial effects: the device has a simple structure, reasonable design, and is easy to use. After the chip completes the high-temperature chip detection work, it is necessary to sort the qualified or unqualified chips. The chips are input to the sorting mechanism, and the chips are sorted by the sorting mechanism. When the sorting mechanism is working, the sorting seat first moves to the designated position to receive the qualified or unqualified chips into the chip conveying channel of the sorting seat. If the received chip is unqualified, the sorting seat moves to the input end of the unqualified chip conveying channel, and the chip conveying channel of the sorting seat is aligned and connected with the unqualified chip conveying channel. At this time, the sorting telescopic cylinder of the sorting seat drives the sorting block to move upward, and the output end position of the chip conveying channel is unblocked, so the chip in the conveying channel in the sorting seat can slide to the inside of the unqualified chip conveying channel; similarly, when the received chip is a qualified chip, the sorting seat moves to the input end of the qualified chip conveying channel, and the chip conveying channel of the sorting seat is aligned and connected with the qualified chip conveying channel. At this time, the sorting telescopic cylinder of the sorting seat drives the sorting block to move upward, and the output end position of the chip conveying channel is unblocked, so the chip in the conveying channel in the sorting seat can slide to the inside of the qualified chip conveying channel;

[0018] Since the chip has just undergone high-temperature testing, the chip itself has a relatively high temperature at this time and needs to be cooled; when the qualified chips enter the qualified chip conveying channel in turn, the first blowing head above the qualified chip conveying channel blows air at an angle along the length direction of the qualified chip conveying channel to cool the qualified chips, and the chips in the qualified chip conveying channel enter the qualified material receiving sleeve one by one, which can ensure that the chips that have not entered the qualified material receiving sleeve can stay in the qualified chip conveying channel for a longer time, thereby increasing the blowing and cooling time, which is conducive to better cooling of the chips; when the chips in the qualified chip conveying channel need to enter the qualified material receiving sleeve, the finger cylinder drives the first stopper to move upward, so that the chip closest to the output end in the qualified chip conveying channel can be output, and at the same time the stopper moves downward to press the second chip. After the first chip is output, the first stopper is reset downward, the stopper is reset upward, and the second chip moves to the original position of the first chip. The third chip moves to the position where the second chip was originally located, and this cycle repeats; when a certain number of chips are installed in the qualified material receiving sleeve, the push block cylinder drives the push block and the qualified material receiving sleeve to move toward the blanking trough. When the push block and the qualified material receiving sleeve move to the edge of the blanking trough, the blocking pressure cylinder drives the blocking pressure block to move upward. When the push block cylinder drives the push block to reset, the qualified material receiving sleeve is blocked by the blocking pressure block and will not reset with the push block again. At this time, the push block is reset, and The qualified material receiving sleeve is blocked by the blocking block and is pushed out into the blanking trough under the reaction force. When the qualified material receiving sleeve is pushed toward the blanking trough, since an L-shaped positioning plate is arranged in front of the rear blanking seat, the open end of the qualified material receiving sleeve will not fall first, and the closed end of the qualified material receiving sleeve will fall into the blanking trough first due to the lack of support, and then the open end of the qualified material receiving sleeve will slide into the blanking trough, thereby ensuring that the chips in the qualified material receiving sleeve will not fall out from the open end of the qualified material receiving sleeve. When the qualified chips enter the unqualified chip conveying channel one by one, the gas blown out by the second blowing head can be blown along the length direction of the unqualified chip conveying channel, so that all the chips in the unqualified chip conveying channel can be blown, which is conducive to faster cooling of the chips in the unqualified chip conveying channel; when the unqualified chips in the unqualified chip conveying channel are cooled down, the second cylinder drives the second stopper to move downward and leave the unqualified chip conveying channel. The unqualified chips lose the obstruction of the second stopper and can enter the unqualified material receiving sleeve from the unqualified chip conveying channel for storage.

[0047] When the sorting mechanism is working: when the chip after high-temperature detection is input into the chip conveying channel of the sorting seat, the belt drive mechanism drives the sorting seat to move to the input end position of the qualified chip conveying and cooling mechanism or the unqualified chip conveying and cooling mechanism, and then the sorting telescopic cylinder drives the sorting block to move upward, and the chip is conveyed along the chip conveying channel to the qualified chip conveying and cooling mechanism or the unqualified chip conveying and cooling mechanism. After the chips in the sorting seat are conveyed, the sorting telescopic cylinder drives the sorting block to reset.

[0048] In an embodiment of the utility model, the first air blowing mechanism 302 includes a first air blowing head 3021 arranged at an interval above the qualified chip conveying channel, a first air blowing channel 3022 is arranged inside the first air blowing head, and the air port of the first air blowing channel is inclined toward the qualified chip conveying channel to ensure that the gas blown out by the first air blowing head can be blown along the length direction of the qualified chip conveying channel, so that all the chips in the qualified chip conveying channel can be blown, which is conducive to faster cooling of the chips in the qualified chip conveying channel; the above-mentioned first air blowing head is connected to an external air source via an air pipe.

[0055] A fixed block 311 is provided at the bottom of the rear blanking seat 3092, a mounting block 312 is provided below the front blanking seat 3091, a movable block 313 that moves forward and backward is provided in the middle of the mounting block, the movable block is located on the inner bottom surface of the front blanking seat, the upper surface of the movable block is higher than the upper surface of the mounting block, a top opening 314 for supporting the end of a qualified material receiving sleeve is provided at the rear of the movable block, the top opening includes an upper rectangular top opening and a lower triangular top opening, and the movable block is driven to move by a first cylinder 315 provided in front of the mounting block;

[0056] When the qualified receiving sleeve filled with chips at the bottom is conveyed into the blanking trough, the new qualified receiving sleeve falls downward to the movable block surface of the front blanking seat and the fixed block surface of the rear blanking seat. The first cylinder first drives the movable block to retract forward, and then the closed end part of the new qualified receiving sleeve is separated from the movable block surface, and the closed end part of the qualified receiving sleeve moves downward for a distance and is supported by the mounting block surface. At this time, the first cylinder drives the movable block to move backward again, and the top of the movable block abuts against the closed end part of the qualified receiving sleeve, and pushes the qualified receiving sleeve backward, so that the open end of the qualified receiving sleeve passes through the slot of the rear blanking seat until the open end of the qualified receiving sleeve is aligned and connected with the output end of the qualified chip conveying channel; then the pressure block of the pressure block structure of the rear blanking seat presses down on the rear end surface of the qualified receiving sleeve to further limit the qualified receiving sleeve.

[0057] A pressure block structure 316 is arranged at the rear of the rear blanking seat, and the pressure block mechanism includes a vertical guide rail 3161 installed on the rear blanking seat, and a vertical slide 3162 which can slide along the vertical guide rail is sleeved on the vertical guide rail, and a pressure block 3163 is arranged below the vertical slide, and a pressure groove suitable for receiving a qualified sleeve is arranged below the pressure block, and a third cylinder 3164 for driving the vertical slide and the pressure block to rise and fall is arranged above the vertical slide; the third cylinder is installed on the rear blanking seat through the third cylinder seat 3165, and the output shaft of the third cylinder is sleeved with a spring 3166 on the outside, and the two ends of the spring are against the third cylinder seat and the vertical slide, and the third cylinder can drive the pressure block to press down the rear end surface of the qualified receiving sleeve, so as to better limit the qualified receiving sleeve.

[0058] The qualified sleeve blanking mechanism 310 includes two push blocks 3101, which are arranged at the front and rear lower parts of the lowest qualified receiving sleeve, and a connecting block 3102 is arranged between the two push blocks. A push block cylinder 3103 is arranged on the side of the connecting block, and the output shaft of the push block cylinder is connected to the connecting block.

[0059] When the qualified sleeve blanking mechanism is working: when a certain number of chips are loaded in the qualified material receiving sleeve, the push block cylinder drives the push block and the qualified material receiving sleeve on the push block to move toward the blanking trough. When the qualified material receiving sleeve moves to the edge of the blanking trough with the push block, the blocking pressure cylinder located at the edge drives the blocking pressure block to move upward. When the push block cylinder drives the push block to reset, the qualified material receiving sleeve is blocked by the blocking pressure block and will not reset again with the push block, so that the qualified material receiving sleeve falls into the blanking trough; at the same time, since the open end of the qualified material receiving sleeve is provided with an L-shaped clamping plate, the open end of the qualified material receiving sleeve is restricted from falling first, which can ensure the closure of the qualified material receiving sleeve. The end first falls into the drop trough, and the open end of the qualified receiving sleeve slowly slides down, thereby preventing the chips in the qualified receiving sleeve from falling out from the open end of the qualified receiving sleeve; it is worth explaining here that the drop trough is an inclined surface. When the qualified receiving sleeve falls into the drop trough, the qualified receiving sleeve is in an inclined state, that is, the height of the closed end of the qualified receiving sleeve is less than the height of the open end of the qualified receiving sleeve. At the same time, the chips in the qualified receiving sleeve will not be full, and the chip closest to the opening of the qualified receiving sleeve is still some distance away from the open end of the qualified receiving sleeve, thereby ensuring that when the qualified receiving sleeve falls into the drop trough, the chip is not easily shaken out.

[0060] In an embodiment of the utility model, the second air blowing mechanism 402 includes a second air blowing head 4021 arranged above the unqualified chip conveying channel, and a plurality of unqualified chip conveying channels are arranged side by side. A plurality of second air blowing grooves 4022 are correspondingly arranged inside the second air blowing head. The air blowing port of each second air blowing groove is inclined toward each unqualified chip conveying channel, and a connector 4023 for connecting to an external air source is provided at the air inlet of each second air blowing groove to ensure that the gas blown out by the second air blowing head can be blown away along the length direction of the unqualified chip conveying channel, so that all chips in the unqualified chip conveying channel can be blown, which is beneficial to faster cooling of the chips in the unqualified chip conveying channel; the above-mentioned second air blowing head is connected to the external air source via an air pipe.

[0061] In the embodiment of the utility model, each unqualified chip conveying channel is provided with a second stopper 403 near its output end to block the channel. The second stopper is driven to rise and fall by a second cylinder 404, and a mounting seat 405 is provided between the second stopper and the output shaft of the second cylinder.

[0062] In the initial state, the second cylinder drives the second stopper to rise upward to the output end of the unqualified chip conveying channel to block the movement of chips in the unqualified chip conveying channel; when the chip is cooled down, the second cylinder drives the second stopper to move downward and leave the unqualified chip conveying channel. The chip loses the obstruction of the second stopper and can enter the unqualified material receiving sleeve from the unqualified chip conveying channel.

[0063] In an embodiment of the utility model, an unqualified material receiving sleeve 406 is provided at the output end of the unqualified chip conveying channel, and the end of the unqualified material receiving sleeve away from the output end of the unqualified chip conveying channel is a closed end, and the end of the unqualified material receiving sleeve away from the output end of the unqualified chip conveying channel is an open end, which is connected and aligned with the output end of the unqualified chip conveying channel, and can receive the chips in the unqualified chip conveying channel into the unqualified material receiving sleeve.

[0064] In an embodiment of the utility model, a fixed socket 407 is arranged in front of the unqualified chip conveying channel, a slot 408 for inserting and fixing an unqualified material receiving sleeve is arranged in the middle of the fixed socket, and an elastic fixing mechanism 409 is arranged inside the slot; the elastic fixing mechanism includes a fixed seat 4091 arranged under the base, and a fixed spring piece 4092 is arranged on the fixed seat, and the fixed spring piece includes an inclined portion 4093 and an arc portion 4094, and the arc portion extends into the slot to contact with the unqualified chip conveying channel.

[0065] When the unqualified material receiving sleeve is fixed: by inserting the unqualified material receiving sleeve along the slot of the fixed socket until the opening end of the unqualified material receiving sleeve contacts the output end of the unqualified chip conveying channel, the output port of the unqualified chip conveying channel is aligned with the opening end of the qualified material receiving sleeve, and when the unqualified material receiving sleeve is inserted, the fixed spring piece is squeezed downward by the insertion of the unqualified material receiving sleeve, thereby forming a limit for the unqualified material receiving sleeve by the fixed spring piece.

[0066] In the embodiment of the utility model, when the high temperature test cooling device of the sorting machine is working:

[0067] After the chip completes the high-temperature chip detection work, it is necessary to sort the qualified or unqualified chips. The chips are input into the sorting mechanism, and the chips are sorted by the sorting mechanism. When the sorting mechanism is working, the sorting seat first moves to the designated position to receive qualified or unqualified chips to the chip conveying channel of the sorting seat. If the received chip is unqualified, the sorting seat moves to the input end of the unqualified chip conveying channel, and the chip conveying channel of the sorting seat is aligned and connected with the unqualified chip conveying channel. At this time, the sorting telescopic cylinder of the sorting seat drives the sorting block to move upward, and the output end position of the chip conveying channel is unblocked, then the chip in the conveying channel in the sorting seat can slide to the inside of the unqualified chip conveying channel; similarly, when the received chip is a qualified chip, the sorting seat moves to the input end of the qualified chip conveying channel, and the chip conveying channel of the sorting seat is aligned and connected with the qualified chip conveying channel. At this time, the sorting telescopic cylinder of the sorting seat drives the sorting block to move upward, and the output end position of the chip conveying channel is unblocked, then the chip in the conveying channel in the sorting seat can slide to the inside of the qualified chip conveying channel;

[0068] Since the chip has just undergone high-temperature testing, the chip itself has a relatively high temperature at this time and needs to be cooled; when the qualified chips enter the qualified chip conveying channel in turn, the first blowing head above the qualified chip conveying channel blows air at an angle along the length direction of the qualified chip conveying channel to cool the qualified chips, and the chips in the qualified chip conveying channel enter the qualified material receiving sleeve one by one, which can ensure that the chips that have not entered the qualified material receiving sleeve can stay in the qualified chip conveying channel for a longer time, thereby increasing the blowing and cooling time, which is conducive to better cooling of the chips; when the chips in the qualified chip conveying channel need to enter the qualified material receiving sleeve, the finger cylinder drives the first stopper to move upward, so that the chip closest to the output end in the qualified chip conveying channel can be output, and at the same time the stopper moves downward to press the second chip. After the first chip is output, the first stopper is reset downward, the stopper is reset upward, and the second chip moves to the original position of the first chip. The third chip moves to the position where the second chip was originally located, and this cycle repeats; when a certain number of chips are installed in the qualified material receiving sleeve, the push block cylinder drives the push block and the qualified material receiving sleeve to move toward the blanking trough. When the push block and the qualified material receiving sleeve move to the edge of the blanking trough, the blocking pressure cylinder drives the blocking pressure block to move upward. When the push block cylinder drives the push block to reset, the qualified material receiving sleeve is blocked by the blocking pressure block and will not reset with the push block again. At this time, the push block is reset, and The qualified material receiving sleeve is blocked by the blocking block and is pushed out into the blanking trough under the reaction force. When the qualified material receiving sleeve is pushed toward the blanking trough, since an L-shaped positioning plate is arranged in front of the rear blanking seat, the open end of the qualified material receiving sleeve will not fall first, and the closed end of the qualified material receiving sleeve will fall into the blanking trough first due to the lack of support, and then the open end of the qualified material receiving sleeve will slide into the blanking trough, thereby ensuring that the chips in the qualified material receiving sleeve will not fall out from the open end of the qualified material receiving sleeve.

[0069] When the qualified chips enter the unqualified chip conveying channel one by one, the gas blown out by the second blowing head can be blown along the length direction of the unqualified chip conveying channel, so that all the chips in the unqualified chip conveying channel can be blown, which is conducive to faster cooling of the chips in the unqualified chip conveying channel; when the unqualified chips in the unqualified chip conveying channel are cooled down, the second cylinder drives the second stopper to move downward and leave the unqualified chip conveying channel. The unqualified chips lose the obstruction of the second stopper and can enter the unqualified material receiving sleeve from the unqualified chip conveying channel for storage.
