Description

Technical Field

[0001] The present invention relates to the field of chip detection equipment, especially to the field of tooling equipment for chip aging test, and specifically to a chip placing device for chip aging test. Background Art

[0002] With the rapid development of semiconductor technology and the increasing complexity of chips year by year, chip testing has run through the entire design, R & D and production process and has become increasingly challenging. Among them, aging test is an important test for eliminating early failure products before the chips are delivered to customers for use. Usually, for chip aging test, each chip to be tested needs to be placed in the test socket of the aging test fixture board first, and then the aging test fixture board with the chips clamped is put into the aging test equipment for aging test; in order to improve the efficiency of chip aging test, most of the existing aging test fixture boards are arranged with multiple chip test sockets in a matrix form, but in the actual operation process, the chips to be tested are manually placed and inserted into the chip test sockets of the aging test fixture board one by one. Similarly, after the chips after aging test are cooled, the tested chips also need to be taken out of the aging test fixture one by one manually and classified and stored according to the test results as qualified products and unqualified products; this leads to the problems of low efficiency of the entire chip aging test and high working intensity of workers. At present, in this field, an automatic placing mechanism that uses a manipulator to place chips into the aging test sockets of the aging test fixture board has gradually emerged, but this placing mechanism still requires manual taking and placing of the aging test fixture board during operation, so there is still a problem of low efficiency.

The front side transfer trolley 50a is pushed towards the frame lifting assembly 70 located in the longitudinal front side (i.e., the frame lifting assembly 70 of the fixture board upper plate mechanism 30). During this process, on the one hand, the frame support bracket 72 of the frame lifting assembly 70 gradually extends into the bottom of the frame rail 60a of the front side transfer trolley 50a until the frame rail 60a is completely supported by the frame support bracket 72. At this time, the front side transfer trolley 50a abuts against the bottom gearbox 71 in the frame lifting assembly 70 of the fixture board upper plate mechanism 30. On the other hand, the second top plate 331 of the fixed frame in the fixture board upper plate mechanism 30 extends into the frame rail 60a from the open area at the longitudinal rear side until the second top plate 331 is located above the aging test fixture board within the frame rail 60a; Subsequently, the rotary cylinder 77 in the front side transfer trolley locking assembly operates, thereby driving the locking plate 78 to rotate and locking the positioning lock block of the front side transfer trolley 50a to the bottom gearbox 71;Meanwhile, the longitudinal linear module 32 of the upper plate mechanism 30 of the fixture plate operates and drives its slide table 321 to drive the loading push plate 31 to translate forward longitudinally to the most forward side. Then, the lifting drive motor 73 in the frame lifting mechanism rotates. The lifting drive motor 73 drives the second drive gear 742, and the second drive gear 742 drives the second transmission gear 743 to rotate. Thereby, the lifting transmission lead screw 741 is driven to rotate, and the nut connecting piece 724, the transmission connecting plate 723, and the frame support bracket 72 as a whole are driven to rise through the lead screw nut. Thus, the frame bar 60a supported on the frame support bracket 72 is lifted synchronously until the first aging test fixture plate located at the uppermost part within the frame bar 60a reaches below the loading push plate 31 of the upper plate mechanism 30 of the fixture plate. Then, the longitudinal linear module 32 drives its slide table 321 to operate, and the slide table 321 drives the loading push plate 31 to translate backward longitudinally. Thus, the right-angled barb 31a at the longitudinal front end of the loading push plate 31 can hook the first aging test fixture plate located at the uppermost part and drive it to translate backward longitudinally and leave the frame bar 60a from the open part at the longitudinal rear side and enter the position of the fixture plate bearing mechanism 20 through the top platform plate 76 of the frame lifting mechanism. Subsequently, under the limiting and guiding action of the limiting bars 231a and 231b, the aging test fixture plate translates onto the support plate 221 until the longitudinal rear end face of the aging test fixture plate is abutted and limited by the limiting plate 234 (before this, the support plate 221 has been driven by the lifting cylinder 222 to descend to the same height as the limiting plane of the limiting bars 231a and 231b, and the limiting plate 234 has risen to the same height as the limiting plane of the limiting bars 231a and 231b under the lifting drive of the cylinder 232). Subsequently, the lifting cylinder 222 pushes the support plate 221, and the support plate 221 drives the aging test fixture plate to rise vertically together until the aging test fixture plate abuts tightly against the bottom surface of the positioning pressure plate 235. At this time, each chip socket on the aging test fixture plate is located below the chip positioning hole 238 at the corresponding position of the positioning pressure plate 235, thereby realizing the positioning and support of the first aging test fixture plate. Subsequently, the manipulator picks up or sucks the chips from the chip tray and transfers and places the chips into the chip sockets of the aging test fixture plate on the support plate 221 until all the chip sockets of the entire aging test fixture plate are filled with chips. Then, the lifting cylinder 222 descends and resets, thereby driving the support plate 221 and the aging test fixture plate to descend together until the lateral two sides of the aging test fixture plate are respectively supported and limited by the limiting bars 231a and 231b, and at the same time, the cylinder 232 drives the limiting plate 234 to descend together;After that, the lower plate mechanism 40 of the fixture plate starts to work (during the process of loading the aging test fixture plate onto the support plate 221, the unloading push plate 41 of the lower plate mechanism 40 of the fixture plate tilts upward under the action of the push plate rotation mechanism 43 to form an avoidance state to prevent it from hindering the upper plate operation of the support plate 421). The driving rotating link 432 of the push plate rotation mechanism 43 rotates around the longitudinal rotating shaft 434, and then drives the unloading push plate 41 to rotate by the rotating link 432 until the unloading push plate 41 is in a horizontal state extending longitudinally backward and is located at the longitudinal front end side of the aging test fixture plate. The longitudinal movement servo motor 421 rotates to drive the first driving gear, the first transmission belt 425, and the first transmission gear 423 to act. Then, the first transmission belt 425 drives the longitudinal movement slider 422 and the push plate rotation assembly 43 connected and installed on the first longitudinal movement slider 422 to move longitudinally backward along the longitudinal movement slide rail 426 as a whole. Thus, the horizontally placed unloading push plate 41 at the end of the rotating link 432 installed on the push plate rotation assembly 43 moves longitudinally backward synchronously. As a result, the unloading push plate 41 pushes the aging test fixture plate to move longitudinally backward. After passing through the top platform plate 76 of the frame lifting assembly 70 of the lower plate mechanism 40 of the fixture plate, it slides into the empty frame bar 60b carried by the rear transfer trolley 50b from the open area at the longitudinal front side (at this time, the frame bar 60b has been lifted by the frame lifting assembly 70 of the lower plate mechanism 40 of the fixture plate to a state where the bottom surface of its frame is at the same height as the top platform plate 76 of the frame lifting assembly 70). Thus, the process of loading the upper plate of an aging test fixture plate, arranging the chips on the plate, and unloading the lower plate of the aging test fixture plate is completed. After that, the frame lifting assembly 70 of the upper plate mechanism 30 of the fixture plate drives the frame bar 60a to rise by a distance equal to the overall height of an aging test fixture plate. The longitudinal movement servo motor 421 of the lower plate mechanism 40 of the fixture plate rotates in the reverse direction to make the unloading push plate 41 move longitudinally forward and return to the avoidance state when loading the upper plate of the aging test fixture plate. At the same time, the frame lifting mechanism 70 of the lower plate mechanism 40 of the fixture plate drives the frame bar 60b to descend by a distance equal to the overall height of an aging test fixture plate. Then, the operation of loading the upper plate of the next aging test fixture plate, placing the chips, and unloading the lower plate of the fixture plate is carried out until all the aging test fixture plates in the front frame bar 50a are fully filled with chips and then unloaded and stacked into the frame bar 60b.;
