[0033] Traditional chip testing mainly involves manually placing a single chip into a detection device for testing, and then manually classifying and arranging the tested chips after the test. The production efficiency is low and cannot meet the requirements of large-scale and high-efficiency production.

[0034] The following is a preferred embodiment of a chip testing machine and a chip loading and unloading device provided by the present invention that can solve the above technical problems.

[0035] A preferred embodiment of the present invention provides a chip testing machine. Please refer to Figure 1 , the chip testing machine includes a chip loading and unloading device 1 and a detection device 2. The detection device 2 is used to test the chip to be tested, and the chip loading and unloading device 1 is used to move the chips to be tested to the detection device 2 one by one, and then unload the tested chips one by one.

[0036] Please refer to Figures 1-8, the chip loading and unloading device 1 includes a mounting frame 11, a plurality of cassettes 12, a plurality of lifting mechanisms 13, a cassette changing mechanism 14 and a manipulator 15. The mounting frame 11 is provided with a plurality of bins 111 arranged horizontally. Each cassette 12 is used to carry a plurality of chips, and the plurality of cassettes 12 can be arranged vertically in the bins 111. The plurality of lifting mechanisms 13 are respectively arranged in the plurality of bins 111 in one-to-one correspondence. The lifting mechanism 13 includes a lifting plate 131 and a lifting driver 132. The lifting driver 132 is arranged on the mounting frame 11 and is connected to the lifting plate 131 for driving the lifting plate 131 to move vertically to drive the cassette 12 to rise and fall.

[0037] The cassette changing mechanism 14 is arranged on one longitudinal side of the bin 111 and is used to move the cassette 12 between two bins 111. The cassette changing mechanism 14 includes a cassette clamping and placing component 141 and a transverse driving member 142. The cassette clamping and placing component 141 includes a cassette arm 1411, a vertical driving member 1412 and a longitudinal driving member 1413. The cassette arm 1411 is used to clamp the cassette 12. The vertical driving member 1412 is connected to the cassette arm 1411 and is used to drive the cassette arm 1411 to move vertically. The longitudinal driving member 1413 is connected to the vertical driving member 1412 and is used to drive the vertical driving member 1412 and the cassette arm 1411 to move longitudinally so that the cassette arm 1411 can enter and exit the bin 111. The transverse driving member 142 is connected to the longitudinal driving member 1413 and is used to drive the cassette clamping and placing component 141 to move horizontally so that the cassette 12 can be moved to the corresponding bin 111.

[0038] The manipulator 15 is arranged on the mounting frame 11 and is used to pick and place chips at the top of the bin 111 and transfer the chips between the cassette 12 and the detection device 2.

[0039] In the figure, the x direction is the horizontal direction, the y direction is the longitudinal direction, and the z direction is the vertical direction.

[0040] The chip loading and unloading device 1 and the chip tester of the present invention, during operation, place a stack of cassettes 12 filled with chips to be tested in one of the storage bins 111. The lifting driver 132 drives the lifting plate 131 to move upward, thereby jacking up the stack of cassettes 12 until the uppermost cassette 12 reaches the specified position. The manipulator 15 takes away the multiple chips to be tested on the uppermost cassette 12 one by one and sends them to the detection device 2 for testing. After the uppermost cassette 12 is empty, the lateral driving member 142 drives the cassette clamping and placing assembly 141 to move laterally to the storage bin 111. The longitudinal driving member 1413 drives the cassette arm 1411 to move longitudinally into the storage bin 111. The vertical driving member 1412 drives the cassette arm 1411 to move downward vertically. The cassette arm 1411 clamps the empty cassette 12 and moves upward, exits the storage bin 111 longitudinally, and moves laterally to other storage bins 111, and places the empty cassette 12 into the storage bin 111. The lifting driver 132 drives the lifting plate 131 to continue moving upward, continues to jack up all the cassettes 12 until the uppermost cassette 12 reaches the specified position, and performs cyclic operation. If the chips are qualified after the chip test, the manipulator 15 places the qualified chips on the cassettes 12 in the corresponding storage bins 111. After the uppermost cassette 12 is filled with qualified chips, the lifting driver 132 drives the lifting plate 131 to move downward. The cassette changing mechanism 14 places an empty cassette 12 on the uppermost part of the lifting plate 131 and continues to load qualified chips, performing cyclic operation. Similarly, if the chips are defective after the chip test, the manipulator 15 places the defective chips on the cassettes 12 in the corresponding storage bins 111. After the uppermost cassette 12 is filled with defective chips, the lifting driver 132 drives the lifting plate 131 to move downward. The cassette changing mechanism 14 places an empty cassette 12 on the uppermost part of the lifting plate 131 and continues to load unqualified chips, performing cyclic operation. The chip loading and unloading device 1 and the chip tester of the present invention can automatically take away the chips to be tested one by one for testing and automatically classify and place the tested chips, improving the production efficiency.

[0041] Please refer to Figure 3 and Figure 4, the lifting mechanism 13 is located on the lateral side of the corresponding storage bin 111. A tray 16 is provided at the bottom of each storage bin 111. The tray 16 is slidably connected to the mounting rack 11 longitudinally. The tray 16 is provided with an avoidance notch 161. The tray 16 includes a first position and a second position on its sliding track. When the tray 16 is in the first position, the tray 16 is located inside the storage bin 111, and the avoidance notch 161 is vertically opposite to the lifting disc 131 to prevent the tray 16 from affecting the vertical movement of the lifting disc 131. When the tray 16 is in the second position, the tray 16 extends outside the storage bin 111 and is farther from the cartridge changing mechanism 14 relative to the first position. During operation, the tray 16 is pulled from the first position to the second position, and a stack of cartridges 12 filled with chips to be tested can be placed on the tray 16 outside the storage bin 111. Then, the tray 16 is pushed back to the first position, and a stack of cartridges 12 filled with chips to be tested is located in the storage bin 111. With the above structure, it is convenient to place the cartridges 12 filled with chips to be tested in the storage bin 111. The usage method of other storage bins 111 is similar to that of the above storage bin 111. With the above structure, it is convenient to take out the cartridges 12 filled with defective chips and qualified chips from the storage bin 111. The lifting mechanism 13 is located on the lateral side of the corresponding storage bin 111, which can prevent affecting the longitudinal movement of the tray 16.

[0042] Please refer to Figure 4 and Figure 9 , each tray 16 is provided with a locking hole 162, and the axial direction of the locking hole 162 is horizontal. The chip loading and unloading device 1 further includes a plurality of locking devices 17. The locking device 17 includes a locking shaft 171 and a locking cylinder 172. The locking shaft 171 moves horizontally at the locking hole 162. The locking cylinder 172 is arranged on the mounting rack 11 and is connected to the locking shaft 171 for driving the locking shaft 171 to move horizontally in and out of the locking hole 162 to lock or unlock the tray 16 at the first position. After the tray 16 is loaded with the cartridge 12 and moved to the first position, the locking cylinder 172 is used to move the locking shaft 171 into the locking hole 162, which can lock the tray 16 at the first position, prevent it from moving longitudinally, and avoid the manipulator 15 being unable to smoothly pick up or place chips on the cartridge 12. The locking cylinder 172 drives the locking shaft 171 to move outside the locking hole 162 to release the locking of the tray 16 at the first position, and the tray 16 can be pulled out without affecting normal use.

[0043] Please refer to Figure 4, the tray 16 includes a connecting plate 163 and two extension plates 164. The connecting plate 163 extends longitudinally and is slidably connected to the mounting frame 11. The two extension plates 164 are both connected to the connecting plate 163, arranged at intervals longitudinally, and extend transversely. A clearance notch 161 is formed between the two extension plates 164. The lifting plate 131 can lift the cartridge 12 upward through the clearance notch 161 surrounded by the connecting plate 163 and the two extension plates 164, which is convenient for operation and manufacturing.

[0044] Corner limit blocks 165 are provided at both transverse ends of the two extension plates 164. The four corner limit blocks 165 are used to limit the four corners of the cartridge 12. Limiting the four corners of the cartridge 12 by the four corner limit blocks 165 can prevent the cartridge 12 from shifting.

[0045] Please refer to Figure 1 , a working surface 112 is provided at the top of the mounting frame 11. The magazine 111 and the cassette changing mechanism 14 are located below the working surface 112.

By clamping both horizontal sides of the cartridge 12 with the first clamping jaws 14114 on both horizontal sides of the base plate 14112 and clamping both vertical sides of the cartridge 12 with the second clamping jaws 14117 on both vertical sides of the base plate 14112, the cartridge 12 can be stably clamped. The first clamping driver 14115 is arranged between the base plate 14112 and the mounting plate 14111, and the second clamping driver 14118 is arranged between the base plate 14112 and the mounting plate 14111, which can effectively protect the first clamping driver 14115 and the second clamping driver 14118.

[0052] Please refer to Figure 8 Figure 8 , the cassette arm 1411 further includes at least four guiding blocks 14119. The four sides of the substrate 14112 are provided with guiding blocks 14119, and the guiding blocks 14119 protrude downward from the substrate 14112 for guiding the chip cassette 12. During operation, the cassette arm 1411 moves downward, and the guiding blocks 14119 first move to the position of the cassette 12. The cassette 12 is guided and positioned around by at least four guiding blocks 14119, and then the cassette 12 is clamped by the cooperation of at least two first clamping components 14113 and at least two second clamping components 14116, which can improve the accuracy of clamping the cassette 12.

[0053] The working principle of the chip tester according to the preferred embodiment of the present invention: Pull the tray 16 of the chip bin to be tested to the second position, place a stack of cartridge cases 12 filled with chips to be tested on the tray 16, and then push the tray 16 to the first position. The lifting driver 132 drives the lifting plate 131 to move upward, thereby jacking up the stack of cartridge cases 12 until the uppermost cartridge case 12 reaches the designated position. The manipulator 15 takes the chips to be tested on the uppermost cartridge case 12 and sends them to the testing device 2 for testing. After the uppermost cartridge case 12 is empty, the lateral driving member 142 drives the cartridge case clamping and placing assembly 141 to move laterally to the chip bin to be tested. The longitudinal driving member 1413 drives the cartridge case arm 1411 to move longitudinally into the chip bin to be tested, and the vertical driving member 1412 drives the cartridge case arm 1411 to move downward vertically.

[0054] In this way, the working process of the chip testing machine of the present preferred embodiment is completed.

[0055] For the chip loading and unloading device and chip testing machine of the present invention, during operation, a stack of cartridges filled with chips to be tested is placed in one of the storage bins. The lifting driver drives the lifting plate to move upward, thereby jacking up the stack of cartridges until the uppermost cartridge reaches the specified position. The manipulator picks up the chips to be tested on the uppermost cartridge and sends them to the detection device for testing. After the uppermost cartridge is empty, the lateral driving member drives the cartridge clamping and placing assembly to move laterally to the position of this storage bin. The longitudinal driving member drives the cartridge arm to move longitudinally into the storage bin. The vertical driving member drives the cartridge arm to move downward vertically. The cartridge arm clamps the empty cartridge and moves upward, exits the storage bin along the longitudinal direction, and moves laterally to other storage bins, and places the empty cartridge into this storage bin. The lifting driver drives the lifting plate to continue moving upward, and continues to jack up all the cartridges until the uppermost cartridge reaches the specified position, and the cycle operation is carried out. If the chips are qualified after the chip testing is completed, the manipulator places the qualified chips on the cartridges in the corresponding storage bin. After the uppermost cartridge is filled with qualified chips, the lifting driver drives the lifting plate to move downward. The cartridge changing mechanism places an empty cartridge on the uppermost part of the lifting plate, and continues to load the qualified chips, and the cycle operation is carried out. Similarly, if the chips are defective after the chip testing is completed, the manipulator places the defective chips on the cartridges in the corresponding storage bin. After the uppermost cartridge is filled with defective chips, the lifting driver drives the lifting plate to move downward. The cartridge changing mechanism places an empty cartridge on the uppermost part of the lifting plate, and continues to load the unqualified chips, and the cycle operation is carried out. The chip loading and unloading device and chip testing machine of the present invention can automatically pick up the chips to be tested one by one for testing, and automatically classify and place the tested chips, improving the production efficiency.
