Abstract
Description
Technical Field
[0001] This application relates to the field of chip testing technology, and in particular to a testing device. Background Technology
[0002] After the chip is programmed, it needs to be tested to check if the programming was successful. In related technologies, a robotic arm picks up the chip and places it in the testing slot of a testing fixture. The terminals of the detector are located at the bottom of the testing slot, and the chip contacts the terminals of the detector. The detector is electrically connected to the chip to test it. The testing fixture is usually equipped with a gripper to close the testing slot. When it is necessary to pick up or put down the chip relative to the testing slot, a linkage module is required to cooperate with the gripper to open the testing slot. After the gripper opens the testing slot, the picking module picks up or puts down the chip relative to the testing slot. The picking module and the linkage module are usually driven by two drive modules, which results in the mechanism occupying more space, having a larger size, and higher production costs.

[0039] Reference Figure 2 and Figure 3 The material handling mechanism 1000 according to an embodiment of this application includes: a mounting base 400, a material handling module 200, a linkage module 300, and a drive module 100.
[0040] Mounting base 400 has a first mounting surface 410 and a second mounting surface 420.
[0041] The material handling module 200 includes a first lifting driver 210 and a material handling head 220. The first lifting driver 210 drives the material handling head 220 to lift and lower. The material handling head 220 is used to adsorb chips.
[0042] The linkage module 300 includes a second lifting driver 310 and a pressure plate 320. The second lifting driver 310 is fixed to the second mounting surface 420. The second lifting driver 310 drives the pressure plate 320 to lift and lower. The pressure plate 320 is used to cooperate in pushing the gripper 600 on the detection fixture 500 to open and close the detection slot 510 on the detection fixture 500.
[0043] The drive module 100 drives the mounting base 400 to drive the material handling module 200 and the linkage module 300 to approach or move away from the detection fixture 500 carrying the chip.
[0044] It should be noted that, referring to Figure 1 The material handling mechanism of this application is applied to a testing device, with reference to... Figure 4 The testing equipment also includes a testing mechanism 2000 and a picking mechanism 1000 for picking up and placing chips on the testing mechanism. The testing mechanism 2000 includes a testing fixture 500, a gripper 600, and a detector (not shown in the figure). The testing fixture 500 has a testing slot 510 for placing chips. The terminals of the detector are disposed in the testing slot 510 for electrical connection with the chips in the testing slot 510. The detector can detect the chips in the testing slot 510. The gripper 600 is oscillatingly disposed on the testing fixture 500 to open and close the testing slot.
[0045] Understandably, the drive module 100 can drive the picking module 200 and the linkage module 300 to move, so that the picking module 200 and the linkage module 300 move above the detection fixture 500. Initially, the gripper 600 is positioned to shield the detection slot 510, and the projection of the gripper 600 onto the horizontal plane overlaps with that of the detection slot 510. The gripper 600 would obstruct the picking module 200 from placing the chip into the detection slot 510. Therefore, the linkage module 300 can first push the gripper 600 to swing it, causing the gripper 600 to deviate from the projection of the detection slot 510 onto the horizontal plane. This opens and exposes the detection slot 510, and the gripper 600 no longer obstructs the picking module 200 from placing the chip into the detection slot 510, allowing the picking module 200 to place the chip into the detection slot 510 or remove the chip that has completed detection from the detection slot 510.
[0046] Specifically, after the picking module 200 is moved above the testing fixture 500, the first lifting driver 210 drives the picking head 220 to descend, bringing it closer to the testing slot 510 of the testing fixture 500. The picking head 220 places the chip it has attracted into the testing slot 510. Subsequently, the first lifting driver 210 drives the picking head 220 to rise away from the testing fixture 500. Correspondingly, after the chip testing is completed, the first lifting driver 210 drives the picking head 220 to descend, bringing it closer to the testing slot 510 of the testing fixture 500. The picking head 220 attracts the tested chip in the testing slot 510, and subsequently, the first lifting driver 210 drives the picking head 220 to rise away from the testing fixture 500.
[0047] Understandably, after the pick-up module 200 moves to above the inspection fixture 500, the second lifting driver 310 drives the pressure plate 320 to descend. The pressure plate 320 approaches the gripper 600 on the inspection fixture 500, and the pressure plate 320 pushes the gripper 600 to swing, opening the inspection slot 510. After the pick-up head 220 places the chip into the inspection slot 510, the second lifting driver 310 drives the pressure plate 320 to rise away from the inspection fixture 500, and the gripper 600 swings back to the position covering the inspection slot 510. Correspondingly, after the chip inspection is completed, the second lifting driver 310 drives the pressure plate 320 to descend. The pressure plate 320 approaches the gripper 600 on the inspection fixture 500, and the pressure plate 320 pushes the gripper 600 to swing, opening the inspection slot 510. The pick-up head 220 picks up the inspected chip in the inspection slot 510, and then the second lifting driver 310 drives the pressure plate 320 to rise away from the inspection fixture 500.
[0048] Understandably, both the material handling module 200 and the linkage module 300 are mounted on the mounting base 400. The drive module 100 drives and connects to the mounting base 400. By moving the mounting base 400, the drive module 100 simultaneously moves the material handling module 200 and the linkage module 300, reducing the need for a driver and thus reducing the space occupied by the material handling mechanism 1000, thereby saving production costs. Furthermore, by placing the material handling module 200 and the linkage module 300 on the intersecting first mounting surface 410 and second mounting surface 420 respectively, the space occupied by the material handling mechanism 1000 can be further reduced, making the structure more compact.
[0049] Specifically, the mounting base 400 has an L-shaped cross-section, with the first mounting surface 410 and the second mounting surface 420 perpendicular to each other and being two adjacent vertical surfaces of the L-shaped mounting base 400.
[0050] Specifically, in this embodiment, the drive module 100 includes a translation screw assembly, which drives the mounting base 400 to translate in a straight line, thereby allowing the material handling module 200 and the linkage module 300 to move above the loading station, above the inspection fixture 500, and above the unloading station. In other embodiments, the drive module 100 may also include a lifting screw assembly, which is disposed at the drive end of the translation screw assembly, and the mounting base 400 is disposed at the drive end of the lifting screw assembly. The lifting screw assembly can drive the material handling module 200 and the linkage module 300 to move up and down respectively.
[0051] Reference Figure 2 and Figure 3According to some embodiments of this application, the first lifting driver 210 includes a belt drive assembly 211 and a first motor 212. The mounting base 400 forms a third mounting surface 430 on the side opposite to the first mounting surface 410. The first motor 212 is disposed on the third mounting surface 430. The driving end of the first motor 212 passes through the mounting base 400 and is drivenly connected to the belt drive assembly 211. The belt drive assembly 211 is drivenly connected to the material pick-up head 220. The belt drive assembly 211 is located between the material pick-up module 200 and the first mounting surface 410.
[0052] Understandably, the first motor 212 drives the material handling head 220 to rise and fall via the belt drive assembly 211. The first motor 212 is positioned on the third mounting surface 430, reducing the space occupied on the first mounting surface 410. The third mounting surface 430 and the first mounting surface 410 are located on opposite sides of the mounting base 400. The drive end of the first motor 212 passes through the mounting base 400 and connects to the belt drive assembly 211 on the first mounting surface 410, facilitating connection. Furthermore, the belt drive assembly 211 has a small width and is located between the material handling module 200 and the first mounting surface 410, making good use of the space between them and resulting in a compact structure.
[0053] Reference Figure 2 According to some embodiments of this application, the belt drive assembly 211 includes a first drive wheel 2111, a second drive wheel 2112, and a drive belt 2113. The first drive wheel 2111 and the second drive wheel 2112 are rotatably connected to the first mounting surface 410. A first motor 212 drives the first drive wheel 2111. The drive belt 2113 is wound around the first drive wheel 2111 and the second drive wheel 2112. The material pick-up head 220 is connected to the drive belt 2113. The first drive wheel 2111 and the second drive wheel 2112 are distributed along the height direction. The axis of the first drive wheel 2111 and the axis of the second drive wheel 2112 are both perpendicular to the first mounting surface 410.
[0054] Understandably, the first motor 212 drives the first transmission wheel 2111 to rotate. The first transmission wheel 2111, in conjunction with the second transmission wheel 2112, drives the transmission belt 2113 to rotate. Since the first transmission wheel 2111 and the second transmission wheel 2112 are distributed along the height direction, and the transmission belt 2113 is partially arranged in the vertical direction, the material picker head 220 is connected to the vertical part of the transmission belt 2113. Thus, the first motor 212 drives the first transmission wheel 2111 to rotate forward or backward, thereby driving the transmission belt 2113 to rotate forward or backward. The vertical part of the transmission belt 2113 drives the material picker head 220 to rise and fall. The radial dimensions of the first transmission wheel 2111 and the second transmission wheel 2112 are relatively small. The axis of the first transmission wheel 2111 and the axis of the second transmission wheel 2112 are both perpendicular to the first mounting surface 410, which allows the gap between the material picker module 200 and the first mounting surface 410 to be set smaller, making the structure more compact.
[0055] Reference Figure 2 According to some embodiments of this application, the material handling module 200 further includes a first guide component 240, which includes a first slide rail 241 and a first slide block 242. The first slide rail 241 is fixed to the first mounting surface 410 and is located beside the belt drive component 211. The first slide rail 241 extends along the height direction, and the first slide block 242 is slidably connected to the first slide rail 241. The material handling head 220 is fixed to the first slide block 242.
[0056] Understandably, during the process of the first lifting driver 210 driving the material-taking head 220 to rise and fall, the first slide block 242 moves along the first slide rail 241, and the sliding engagement between the first slide rail 241 and the first slide block 242 guides the rising and falling process of the material-taking head 220. Since both the first slide rail 241 and the belt drive assembly 211 extend along the height direction, placing the first slide rail 241 beside the belt drive assembly 211 utilizes the horizontal space of the first mounting surface 410, making the structure more compact.
[0057] Specifically, the drive belt 2113 of the belt drive assembly 211 is connected to the first slide 242, and the first slide 242 is driven to rise and fall, thereby driving the material pick-up head 220 to rise and fall.
[0058] Reference Figure 2 and Figure 3According to some embodiments of this application, the material handling module 200 further includes a first shielding plate 250 and at least two first position sensors 260. The first position sensors 260 are disposed on the third mounting surface 430. The multiple first position sensors 260 are distributed along the height direction. The first position sensors 260 are electrically connected to the first lifting driver 210. The mounting base 400 has a through groove 440 that penetrates the first mounting surface 410 and the second mounting surface 420. The first shielding plate 250 is movable along the height direction and passes through the through groove 440. One end of the first shielding plate 250 is fixedly connected to the first slide 242, and the other end of the first shielding plate 250 can pass through the detection area of the first position sensor 260.
[0059] It is understandable that when the first slide 242 drives the material handling head 220 to rise and fall, the first baffle 250 rises and falls with the first slide 242. When the first slide 242 slides to a certain horizontal height, the first baffle 250 can pass through the detection area of the first position sensor 260. The first position sensor 260 can transmit the signal to the first lifting driver 210 to control the first lifting driver 210 to stop driving. For example, there are two first position sensors 260. When the first slide 242 rises, it drives the pick-up head 220 away from the detection fixture 500. The first shield 250 will reach the detection area of the first position sensor 260 located at the higher position, that is, the pick-up head 220 has completed picking up or putting down the material. The first lifting driver 210 stops driving so that the pick-up head 220 is kept at the current height. When the first slide 242 falls, it drives the pick-up head 220 closer to the detection fixture 500. The first shield 250 will reach the detection area of the first position sensor 260 located at the lower position, that is, the pick-up head 220 has reached the height where the chip can be placed in the detection slot 510 or can be attracted to the chip in the detection slot 510. The first lifting driver 210 stops driving so that the pick-up head 220 can pick up and put down the chip.
[0060] It is also understandable that the first position sensor 260 is located on the third mounting surface 430, which can reduce the space occupied on the first mounting surface 410. The third mounting surface 430 and the first mounting surface 410 are located on opposite sides of the mounting base 400, and the first shielding plate 250 can cooperate with the first position sensor 260 on the third mounting surface 430 by passing through the through slot 440 on the mounting base 400.
[0061] Reference Figure 2 According to some embodiments of this application, the second lifting driver 310 includes a second motor 311 and a connecting block 312. The second motor 311 is fixed to the second mounting surface 420. The driving end of the second motor 311 is connected to the upper end of the connecting block 312. The connecting block 312 is located between the material picking head 220 and the second mounting surface 420. The pressure plate 320 is fixed to the lower end of the connecting block 312.
[0062] Understandably, the second motor 311 drives the connecting block 312 to rise and fall, thereby raising and lowering the pressure plate 320. The second motor 311 is connected to the upper end of the connecting block 312, and the pressure plate 320 is located at the lower end of the connecting block 312, so that the second motor 311, the connecting block 312, and the pressure plate 320 are distributed along the height direction to utilize the height space on the second mounting surface 420. The connecting block 312 is only used to connect the pressure plate 320 and the second motor 311, and the connecting block 312 is located between the material picking head 220 and the second mounting surface 420. The thickness of the connecting block 312 can be set to be smaller, so that the gap between the material picking head 220 and the second mounting surface 420 can be set to be smaller, making the structure more compact.
[0063] Reference Figure 2 According to some embodiments of this application, the linkage module 300 further includes a second guide component 330, which includes a second slide rail 331 and a second slide block 332. The second slide rail 331 is fixed to the second mounting surface 420. The second slide rail 331 and the second slide block 332 are located between the connecting block 312 and the second mounting surface 420. The second slide rail 331 extends along the height direction. The second slide block 332 is slidably connected to the second slide rail 331. The connecting block 312 is fixed to the second slide block 332.
[0064] Understandably, during the process of the second motor 311 driving the pressure plate 320 to rise and fall via the connecting block 312, the second slide block 332 moves along the second slide rail 331. The sliding cooperation between the second slide rail 331 and the second slide block 332 guides the rising and falling process of the pressure plate 320. Both the second slide rail 331 and the connecting block 312 extend along the height direction, and the second slide rail 331 and the second slide block 332 are positioned between the connecting block 312 and the second mounting surface 420, so that the projections of the connecting block 312, the second slide rail 331, and the second slide block 332 on the second mounting surface 420 overlap, thereby reducing the space occupied in the width direction of the second mounting surface 420.
[0065] Reference Figure 2 According to some embodiments of this application, the linkage module 300 further includes a second shielding plate 340 and at least two second position sensors 350. The second position sensors 350 are disposed on the second mounting surface 420 and located beside the connecting block 312. The multiple second position sensors 350 are distributed along the height direction. The second position sensors 350 are signal connected to the second lifting driver 310. One end of the second shielding plate 340 is fixedly connected to the connecting block 312, and the other end of the second shielding plate 340 can pass through the detection area of the second position sensor 350.
[0066] Understandably, when the connecting block 312 drives the pressure plate 320 to rise and fall, the second baffle 340 rises and falls along with the connecting block 312. When the connecting block 312 slides to a certain horizontal height, the second baffle 340 can pass through the detection area of the second position sensor 350. The second position sensor 350 can transmit this signal to the second lifting driver 310 to control the second lifting driver 310 to stop driving. For example, there are two second position sensors 350. When the connecting block 312 descends, it drives the pressure plate 320 closer to the detection fixture 500. The second baffle 340 will reach the detection area of the second position sensor 350 located at the lower position. That is, the pressure plate 320 has pushed the gripper 600 to a position away from the detection slot 510. The second lifting driver 310 stops driving, keeping the pressure plate 320 at the current height and the gripper 600 at the current position, so that the subsequent pick-up head 220 can pick up and put in the chip. The connecting block 312 rises, causing the pressure plate 320 to move away from the detection fixture 500. The second shielding plate 340 will reach the detection area of the second position sensor 350 located at a high position. That is, the picking head 220 completes the picking of the detected chip and the pressure plate 320 returns to the initial height. The second lifting driver 310 stops driving so that the next chip can be detected.
[0067] Reference Figure 2 According to some embodiments of this application, a clearance hole 321 is provided in the middle of the pressure plate 320, and the material taking head 220 corresponds to the clearance hole 321 along the height direction and can pass through the clearance hole 321.
[0068] Understandably, in the initial state, the pressure plate 320 is located below the pick-up head 220. After the pressure plate 320 pushes the gripper 600, the pick-up head 220 can move down through the clearance hole 321 in the middle of the pressure plate 320 to pick up and put down the chip relative to the detection slot 510.
[0069] Reference Figure 2 According to some embodiments of this application, the material handling module 200 also includes a pump body 230, which is fixed to the mounting base 400, and the suction end of the pump body 230 is connected to the material handling head 220.
[0070] It is understandable that the pump body 230 is connected to the pick-up head 220. When the pump body 230 is working, it can create a vacuum in the pick-up head 220, allowing the pick-up head 220 to pick up the chip. Fixing the pump body 230 to the mounting base 400 reduces the length of the air pipe connecting the pump body 230 and the pick-up head 220. Furthermore, the pump body 230 and the pick-up head 220 move simultaneously with the mounting base 400, thus preventing excessive bending of the air pipe during the movement of the mounting base 400.
[0071] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
