The lifting driver drives the lifting plate to move upward, thus lifting the stack of boxes until the top box reaches the designated position. The robotic arm then picks up the chips to be tested one by one from the top box and sends them to the testing device for testing. Once the top box is empty, the horizontal drive component drives the box clamping assembly to move horizontally to the hopper, the vertical drive component drives the box arm to move vertically into the hopper, and the vertical drive component drives the box arm to move vertically downward. The box arm clamps the empty box and moves upward, then moves vertically out of the hopper and horizontally to another hopper to place the empty box into that hopper.

This automatic chip loading and unloading device and chip testing machine can automatically remove chips one by one for testing and automatically classify and arrange the tested chips, improving production efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0061] Traditional chip testing mainly involves manually placing individual chips into a testing device for testing. After testing, the tested chips are then manually sorted and arranged on trays, resulting in low production efficiency and failing to meet the needs of large-scale, high-efficiency production.
[0062] The following is a preferred embodiment of a chip testing machine and an automatic chip loading and unloading device provided by this utility model, which can solve the above-mentioned technical problems.
[0063] A preferred embodiment of this utility model provides a chip testing machine. Please refer to... Figure 1 The chip testing machine includes an automatic chip loading and unloading device 1 and a testing device 2. The testing device 2 is used to test the chips under test, and the automatic chip loading and unloading device 1 is used to move the chips under test one by one to the testing device 2, and then unload the chips one by one after the testing is completed.
[0064] Please refer to Figures 1-8 The automatic chip loading and unloading device 1 includes a mounting frame 11, multiple material boxes 12, multiple lifting mechanisms 13, a box-changing mechanism 14, and a robotic arm 15. The mounting frame 11 has multiple material boxes 111 arranged horizontally. Each material box 12 carries multiple chips, and the multiple material boxes 12 can be arranged vertically within the material box 111. Multiple lifting mechanisms 13 are respectively arranged one-to-one with each of the multiple material boxes 111. Each lifting mechanism 13 includes a lifting plate 131 and a lifting driver 132. Both sides of the lifting plate 131 have locking blocks 1311, which cooperate to limit the movement of the material boxes 12. The lifting driver 132 is located on the mounting frame 11 and connected to the lifting plate 131, used to drive the lifting plate 131 to move vertically, thereby causing the material boxes 12 to rise and fall.
[0065] A box-changing mechanism 14 is located on one longitudinal side of the hopper 111 and is used to move the box 12 between the two hoppers 111. The box-changing mechanism 14 includes a box-clamping assembly 141 and a lateral drive component 142. The box-clamping assembly 141 includes a box arm 1411, a vertical drive component 1412, and a longitudinal drive component 1413. The box arm 1411 is used to clamp the box 12. The vertical drive component 1412 is connected to the box arm 1411 and is used to drive the box arm 1411 to move vertically. The longitudinal drive component 1413 is connected to the vertical drive component 1412 and is used to drive the vertical drive component 1412 and the box arm 1411 to move longitudinally, so that the box arm 1411 can enter and exit the hopper 111. The lateral drive component 142 is connected to the longitudinal drive component 1413 and is used to drive the box-clamping assembly 141 to move laterally, so that the box 12 can be moved to the corresponding hopper 111.
[0066] The robotic arm 15 is mounted on the mounting frame 11 and is used to pick up and place chips at the top of the hopper 111 and transfer the chips between the hopper 12 and the detection device 2.
[0067] In the diagram, the x-direction is horizontal, the y-direction is vertical, and the z-direction is vertical.
[0068] In operation, the automatic chip loading and unloading device 1 and the chip testing machine of this utility model place a stack of material boxes 12 filled with chips to be tested into one of the material bins 111. The lifting driver 132 drives the lifting plate 131 to move upward, thereby lifting the stack of material boxes 12 upward until the uppermost material box 12 reaches the designated position. The robot arm 15 picks up the multiple chips to be tested from the uppermost material box 12 one by one and sends them to the testing device 2 for testing. Once the topmost hopper 12 is empty, the horizontal drive 142 drives the hopper clamping assembly 141 to move laterally to the hopper 111. The vertical drive 1413 drives the hopper arm 1411 to move longitudinally into the hopper 111. The vertical drive 1412 drives the hopper arm 1411 to move vertically downwards. The hopper arm 1411 clamps the empty hopper 12 and moves upwards, then longitudinally out of the hopper 111, and laterally to another hopper 111 to place the empty hopper 12 into that hopper 111. The lifting drive 132 drives the lifting plate 131 to continue moving upwards, continuing to lift all the hoppers 12 until the topmost hopper 12 reaches the designated position, and the operation is repeated. If the chip is a qualified chip after testing, the robot arm 15 places the qualified chip onto the hopper 12 in the corresponding hopper 111. Once the top hopper 12 is full of qualified chips, the lifting driver 132 drives the lifting platen 131 downwards. The hopper-changing mechanism 14 places the empty hopper 12 on top of the lifting platen 131 and continues loading qualified chips, repeating the cycle. Similarly, if a chip is defective after testing, the robotic arm 15 places the defective chip on the hopper 12 in the corresponding bin 111. Once the top hopper 12 is full of defective chips, the lifting driver 132 drives the lifting platen 131 downwards. The hopper-changing mechanism 14 places the empty hopper 12 on top of the lifting platen 131 and continues loading defective chips, repeating the cycle. This automatic chip loading and unloading device 1 and chip testing machine can automatically remove chips to be tested one by one and automatically classify and place the tested chips, improving production efficiency.
[0069] Please refer to Figure 3 and Figure 4The lifting mechanism 13 is located on the lateral side of the corresponding hopper 111. Each hopper 111 has a tray 16 at its bottom, which is slidably connected to the mounting frame 11 along the longitudinal direction. The tray 16 has a clearance notch 161. The tray 16 has a first position and a second position along its sliding trajectory. When the tray 16 is in the first position, it is inside the hopper 111, and the clearance notch 161 is vertically opposite to the lifting plate 131 to avoid affecting the vertical movement of the lifting plate 131. When the tray 16 is in the second position, it extends to the outside of the hopper 111 and is farther away from the box-changing mechanism 14 relative to the first position. During operation, pulling the tray 16 from the first position to the second position allows a stack of boxes 12 filled with chips to be tested to be placed on the tray 16 outside the hopper 111. Then, pushing the tray 16 back to the first position places the stack of boxes 12 filled with chips to be tested inside the hopper 111. The above structure facilitates the placement of the cassette 12 filled with chips to be tested into the hopper 111. The usage of other hoppers 111 is similar to that of the hopper 111 described above. This structure also facilitates the removal of cassettes 12 filled with defective and qualified chips from the hopper 111. The lifting mechanism 13 is located on the lateral side of the corresponding hopper 111, thus avoiding any impact on the longitudinal movement of the tray 16.
[0070] Please refer to Figure 4 and Figure 9 Each tray 16 is provided with a locking hole 162, the axis of which is transverse. The automatic chip loading and unloading device 1 also includes multiple locking devices 17, each including a locking shaft 171 and a locking cylinder 172. The locking shaft 171 moves laterally at the locking hole 162. The locking cylinder 172 is disposed on the mounting bracket 11 and connected to the locking shaft 171, and is used to drive the locking shaft 171 to move laterally and enter and exit the locking hole 162 to lock or unlock the tray 16 in a first position. After the material box 12 is loaded on the tray 16 and moved to the first position, the locking shaft 171 is moved into the locking hole 162 by the locking cylinder 172, which can lock the tray 16 in the first position, prevent it from moving longitudinally, and prevent the robot arm 15 from being unable to smoothly pick up or place the chip on the material box 12. The locking cylinder 172 drives the locking shaft 171 to move outside the locking hole 162, releasing the locking of the tray 16 in the first position. The tray 16 can then be pulled out without affecting normal use.
[0071] Please refer to Figure 4The 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, are arranged longitudinally at intervals, and extend laterally, forming a clearance notch 161 between the two extension plates 164. The lifting tray 131 can lift the material box 12 upward through the clearance notch 161 formed by the connecting plate 163 and the two extension plates 164, which facilitates operation and manufacturing.
[0072] Corner limiting blocks 165 are provided at both ends of the two extension plates 164. The four corner limiting blocks 165 are used to limit the four corners of the material box 12. By limiting the four corners of the material box 12 with the four corner limiting blocks 165, displacement of the material box 12 can be prevented.
[0073] Please refer to Figure 1 The mounting frame 11 has a working surface 112 on its top. The hopper 111 and the box-changing mechanism 14 are located below the working surface 112. The robot arm 15 is mounted on the working surface 112 and located directly above the box-changing mechanism 14. A material inlet 1121 is provided on the working surface 112 at the position corresponding to the hopper 111 for the robot arm 15 to pick up and put in chips. With the above structure, the entire device can be made compact.
[0074] Please refer to Figure 1 and Figure 2 The multiple hoppers 111 include an empty hopper for recycling, a hopper for chips to be tested, a hopper for qualified chips, a hopper for defective chips, and a hopper for loading empty hoppers. In this embodiment, there are 8 hoppers 111. Figure 1 From left to right, the contents are: an empty material box recycling bin, two chip bins to be tested, two qualified chip bins, two defective chip bins, and an empty material box loading bin.
[0075] There are two robotic arms 15 arranged horizontally. One robotic arm 15 is used to take the chip to be tested from the material box 12 in the chip to be tested hopper from the corresponding material port 1121. The other robotic arm 15 is used to place qualified chips from the corresponding material port 1121 onto the material box 12 in the qualified chip hopper, and to place defective chips from the corresponding material port 1121 onto the material box 12 in the defective chip hopper.
[0076] In this embodiment, the left robotic arm 15 is located at the empty material box recycling bin and the chip to be tested bin, and is used to take the chip to be tested from the material box 12 in the chip to be tested bin from the corresponding material port 1121 and move it to the testing device 2. The right robotic arm 15 is located at the qualified chip bin, the defective chip bin and the empty material box loading bin, and is used to place the qualified chip from the testing device 2 from the corresponding material port 1121 onto the material box 12 in the qualified chip bin, and to place the defective chip from the corresponding material port 1121 onto the material box 12 in the defective chip bin.
[0077] Two robotic arms working simultaneously can effectively improve work efficiency.
[0078] Please refer to Figure 6 and Figure 7 The lateral drive component 142 is a linear motor. There are two material box clamping assemblies 141: one moves empty material boxes 12 from the chip-to-be-tested hopper to the empty material box recycling hopper, and the other moves empty material boxes 12 from the empty material box loading hopper to the qualified chip hopper and the defective chip hopper, respectively. Using a linear motor, the two material box clamping assemblies 141 can be controlled to operate simultaneously, facilitating individual control. The two material box clamping assemblies 141 respectively transfer the material boxes 12 at the loading and unloading points, improving work efficiency.
[0079] Please refer to Figure 8 The material box arm 1411 includes a mounting plate 14111, a base plate 14112, at least two first clamping assemblies 14113, and at least two second clamping assemblies 14116. The mounting plate 14111 is connected to the vertical drive member 1412. The base plate 14112 is fixed below the mounting plate 14111 and the two are spaced apart. The base plate 14112 is square. The first clamping assembly 14113 includes a first gripper 14114 and a first clamping driver 14115. The first gripper 14114 moves laterally and extends to the underside of the substrate 14112. The first gripper 14114 is provided on both sides of the substrate 14112 laterally. The first clamping driver 14115 is disposed between the substrate 14112 and the mounting plate 14111 and is connected to the first gripper 14114. It is used to drive the first gripper 14114 to move laterally. The first gripper 14114 on both sides of the substrate 14112 can clamp the two sides of the material box 12 laterally. The second clamping assembly 14116 includes a second gripper 14117 and a second clamping driver 14118. The second gripper 14117 moves longitudinally and extends below the substrate 14112. The substrate 14112 has two grippers 14117 on each of its longitudinal sides. The second clamping driver 14118 is located between the substrate 14112 and the mounting plate 14111 and is connected to the second gripper 14117. It drives the second gripper 14117 to move longitudinally. The second grippers 14117 on both longitudinal sides of the substrate 14112 can clamp the two longitudinal sides of the material box 12. By clamping the two transverse sides of the material box 12 with the first grippers 14114 on both transverse sides of the substrate 14112 and the two longitudinal sides of the material box 12 with the second grippers 14117 on both longitudinal sides of the substrate 14112, the material box 12 can be clamped stably. The first clamping driver 14115 is disposed between the substrate 14112 and the mounting plate 14111, and the second clamping driver 14118 is disposed between the substrate 14112 and the mounting plate 14111, which can effectively protect the first clamping driver 14115 and the second clamping driver 14118.
[0080] Please refer to Figure 8 The cassette arm 1411 also includes at least four guide blocks 14119. Guide blocks 14119 are provided on all four sides of the substrate 14112, protruding downwards from the substrate 14112 to guide the chip cassette 12. During operation, the cassette arm 1411 moves downwards, and the guide blocks 14119 first move to the cassette 12. The at least four guide blocks 14119 guide and position the cassette 12 around its perimeter. Then, at least two first clamping components 14113 and at least two second clamping components 14116 cooperate to clamp the cassette 12, thereby improving the accuracy of clamping the cassette 12.
[0081] The working principle of the chip testing machine of the preferred embodiment of this utility model:
[0082] The tray 16 of the chip under test hopper is pulled to the second position, and a stack of cassettes 12 filled with chips under test is placed on the tray 16. Then, the tray 16 is pushed to the first position. The lifting driver 132 drives the lifting plate 131 to move upward, thereby lifting the stack of cassettes 12 upward until the top cassette 12 reaches the designated position. The robot arm 15 removes the chip under test from the top cassette 12 and sends it to the testing device 2 for testing. After the top cassette 12 is empty, the horizontal drive 142 drives the cassette clamping assembly 141 to move laterally to the chip under test hopper, the vertical drive 1413 drives the cassette arm 1411 to move longitudinally into the chip under test hopper, and the vertical drive 1412 drives the cassette arm 1411 to move vertically downward. The material box arm 1411 first guides the material box 12 through at least four guide blocks 14119, and then clamps the material box 12 with the cooperation of at least two first clamping components 14113 and at least two second clamping components 14116. After clamping the empty material box 12, the material box arm 1411 moves upward, moves longitudinally to exit the material bin 111, and moves laterally to the empty material box recycling bin, where the empty material box 12 is placed. In the chip under test bin, the lifting driver 132 drives the lifting plate 131 to continue moving upward, continuing to lift all the material boxes 12 upward until the uppermost material box 12 reaches the designated position, and the operation is repeated. If the chip is a qualified chip after testing, the robot arm 15 places the qualified chip on the material box 12 in the qualified chip bin. Once the top hopper 12 is full of qualified chips, the lifting driver 132 drives the lifting platen 131 downwards. The hopper changing mechanism 14 then places the empty hopper 12 from the empty hopper's upper hopper onto the top of the lifting platen 131, continuing to load qualified chips, and the cycle repeats. Similarly, if a chip is defective after testing, the robotic arm 15 places the defective chip onto the hopper 12 in the defective chip hopper. Once the top hopper 12 is full of defective chips, the lifting driver 132 drives the lifting platen 131 downwards. The hopper changing mechanism 14 then places the empty hopper 12 from the empty hopper's upper hopper onto the top of the lifting platen 131, continuing to load unqualified chips, and the cycle repeats.
[0083] This completes the working process of the chip testing machine in this preferred embodiment.
[0084] This invention relates to an automatic chip loading and unloading device and a chip testing machine. During operation, a stack of boxes filled with chips to be tested is placed in one of the hoppers. A lifting driver drives a lifting platen upwards, lifting the stack of boxes until the top box reaches a designated position. A robotic arm then removes the chip from the top box and delivers it to the testing device. Once the top box is empty, a horizontal drive component moves the box clamping assembly horizontally to the hopper, a vertical drive component moves the box arm vertically into the hopper, and a vertical drive component moves the box arm vertically downwards. The box arm clamps the empty box and moves upwards, then vertically out of the hopper and horizontally to another hopper, where an empty box is placed. The lifting driver continues to move the lifting platen upwards, lifting all the boxes until the top box reaches a designated position, and this cycle repeats. If a chip passes the test, the robotic arm places it in the corresponding hopper. Once the top hopper is full of qualified chips, the lifting driver moves the lifting plate downwards, and the hopper-changing mechanism places the empty hopper on top of the lifting plate, continuing to load qualified chips, and the cycle repeats. Similarly, if a chip is found to be defective after testing, the robotic arm places the defective chip on the corresponding hopper. Once the top hopper is full of defective chips, the lifting driver moves the lifting plate downwards, and the hopper-changing mechanism places the empty hopper on top of the lifting plate, continuing to load defective chips, and the cycle repeats. This automatic chip loading and unloading device and chip testing machine can automatically remove chips to be tested one by one and automatically classify and place the tested chips, improving production efficiency.
[0085] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the concept of the technical solution of the present invention, should be included within the scope of protection of the present invention.
