[0003] The warpage laser detection equipment for semiconductor components emits a laser beam to the surface of the semiconductor component. The laser beam is captured by the receiving device after being reflected from the surface of the component.

DETAILED DESCRIPTION
[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0034] like Figures 1 to 11 As shown, a laser detection device for warping of a semiconductor component according to an embodiment of the present invention comprises: a detection box 1, an assembly box 3 is arranged inside the detection box 1, an assembly seat 4 is arranged inside the assembly box 3, an assembly disk 41 is arranged on one side of the assembly seat 4, a vacuum adsorption component 7 is arranged at the bottom of the assembly disk 41, a semiconductor component 42 to be detected is arranged on the top of the assembly disk 41, a laser detection component 6 is arranged on one side inside the detection box 1, the laser detection component 6 is located above the semiconductor component 42 to be detected, side frames 43 are fixed at both ends of the assembly seat 4, a blocking block 1 53 is arranged in the side frame 43, a blocking block 2 54 is arranged on one side of the blocking block 1 53, top rods 5 are arranged on both ends of one side of the top of the assembly box 3, the assembly seat 4 is installed inside the assembly box 3 from bottom to top, and the laser detection component 6 is located above the top assembly disk 41.
[0035] A plurality of semiconductor components 42 to be inspected are mounted on an assembly tray 41, and the semiconductor components 42 to be inspected are adsorbed and fixed by a vacuum adsorption component 7. A plurality of assembly seats 4 are arranged inside the assembly box 3, and an assembly tray 41 is arranged in each assembly seat 4. A semiconductor component 42 to be inspected is mounted on each assembly tray 41. The laser detection component 6 preferentially detects the warpage of the semiconductor component 42 to be inspected at the top, and the position of the semiconductor component 42 to be inspected at the top is set as the detection position, which is marked with a.
[0036] After the inspection of the top semiconductor component 42 to be inspected is completed, the assembly box 3 moves upward, the blocking block 2 54 retracts, and the blocking block 1 53 is no longer blocked, so that the assembly plate 41 located at the top is retracted into the assembly seat 4, and the assembly plate 41 drives the semiconductor component 42 to be inspected installed on the top thereof to be retracted into the assembly seat 4 together;
[0037] After a semiconductor component 42 to be detected located above is retracted into the assembly seat 4, a semiconductor component 42 to be detected below it follows the assembly box 3 to move up to the detection position a. After the detection is completed, the assembly box 3 moves up to make the semiconductor component 42 to be detected that has completed the detection retract into the assembly seat 4, and the next semiconductor component 42 to be detected is moved to the detection position a again. In this way, not only can the device detect multiple semiconductor components 42 to be detected without repeated clamping, thus saving the time required for repeated clamping, but also, the detection distance between the semiconductor component 42 to be detected and the laser detection component 6 is the same each time, thus ensuring the detection of the laser detection component 6, and the detection of the semiconductor component 42 to be detected will not be affected by the change in the distance between the semiconductor component 42 to be detected and the laser detection component 6.
[0038] like Figures 1 to 11As shown, a slide rod 47 is fixed at both ends inside the assembly seat 4, and a slide sleeve 46 is sleeved on the outside of the slide rod 47. The slide sleeve 46 is fixed to both ends of one side of the assembly disk 41, and one end of the slide sleeve 46 is fixedly connected to a blocking block 53. The blocking block 53 is placed in the side frame 43 and can slide in the side frame 43. The blocking block 54 can prevent the assembly disk 41 from moving into the assembly seat 4 by blocking the movement of the blocking block 53. A spring 48 is wound around the outside of the slide rod 47, and one end of the spring 48 is fixedly connected to the slide sleeve 46, and the other end of the spring 48 is fixedly connected to the inner wall of the assembly seat 4. A guide rod 45 is fixed to one side of the assembly disk 41, and the guide rod 45 protrudes from one side of the assembly seat 4.
[0039] In the default state, the assembly plate 41 is retracted into the assembly seat 4. When loading the semiconductor component 42 to be tested, the assembly plate 41 is pulled out of the assembly seat 4, and the assembly plate 41 drives the sliding sleeve 46 and the blocking block 53 to move with it. The sliding sleeve 46 slides outside the sliding rod 47 and pulls one end of the spring 48 to extend it.
[0040] The blocking block 1 53 moves toward the position of the blocking block 2 54. After the inclined surface of the blocking block 1 53 contacts the inclined surface of the blocking block 2 54, the blocking block 2 54 is pushed to retract. When the blocking block 1 53 moves to the straight part of the blocking block 2 54, the blocking block 2 54 is reset. The straight part of the blocking block 2 54 contacts the straight part of the blocking block 1 53 tightly. The blocking block 2 54 blocks the blocking block 1 53, preventing the sliding sleeve 1 46 from moving under the elastic force of the spring 2 48 to retract the assembly disk 41 into the assembly seat 4.
[0041] After the inspection of the semiconductor component 42 to be inspected is completed, the blocking block 2 54 retracts and stops blocking the blocking block 1 53. At this time, the elastic force of the spring 2 48 is used to pull the sliding sleeve 1 46 to move, so as to drive the assembly disk 41 to retract into the assembly seat 4, and the semiconductor component 42 to be inspected mounted on the top of the assembly disk 41 is retracted into the assembly seat 4.
[0042] like Figures 1 to 11 As shown, a side block 44 is fixed at one end of the side frame 43, and a blocking block 2 54 is arranged at the end of the side block 44 facing the side frame 43, and the blocking block 2 54 conflicts with the blocking block 1 53. A guide rod 542 is arranged at the top and bottom ends inside the side block 44, and the guide rod 542 is fixed to the top and bottom ends of the back of the blocking block 2 54. A guide groove 543 is provided at the top and bottom ends of the back of the side block 44, and the guide rod 542 is placed in the guide groove 543 and slides in the guide groove 543. A spring 3 541 is fixed inside the side block 44, and the spring 3 541 is located between the guide rods 542, and one end of the spring 3 541 is fixedly connected to the back of the blocking block 2 54.
[0043] When the assembly plate 41 is pulled out from the assembly seat 4, the blocking block 1 53 moves toward the position of the blocking block 2 54. After the inclined surface of the blocking block 1 53 conflicts with the inclined surface of the blocking block 2 54, the blocking block 2 54 is pushed to retract into the side block 44. The blocking block 2 54 pushes the guide rod 542 to slide in the guide groove 543. The guide rod 542 and the guide groove 543 guide the blocking block 2 54. At the same time, the blocking block 2 54 squeezes the spring 3 541 to contract. When the blocking block 1 53 After moving to the straight part of blocking block 2 54, blocking block 2 54 loses the pressure of blocking block 1 53, and spring 3 541 pushes blocking block 2 54 out of side block 44. At this time, blocking block 2 54 is reset, and the straight part of blocking block 2 54 is tightly pressed against the straight part of blocking block 1 53. Blocking block 2 54 blocks blocking block 1 53 to prevent sliding sleeve 1 46 from moving under the elastic force of spring 2 48 so that assembly disk 41 is retracted into assembly seat 4.
[0044] like Figures 1 to 11 As shown, a sliding sleeve 2 55 is fixed to the top and bottom of the side block 44, a sliding rod 2 56 is arranged inside the sliding sleeve 2 55, and the sliding rod 2 56 is fixed to the push block 2 52. Push blocks 2 52 are fixed on both sides of the side block 44, and a push block 1 51 is arranged above the push block 2 52, and the push block 1 51 is fixed to the top rod 5.
[0045] After the inspection of the top semiconductor component 42 to be inspected is completed, the assembly box 3 moves up, so that the push rod 5 is gradually moved into the assembly box 3, and the push block 1 51 fixed on the push rod 5 moves toward the push block 2 52 on the side walls of the side blocks 44 on both sides of the top assembly seat 4 and pushes downward on the top of the push block 2 52, and the inclined surface of the push block 1 51 is used to push the push block 2 52 to move the side block 44 backward, and the side block 44 drives the sliding sleeve 2 55 to slide outside the sliding rod 2 56, and the blocking block 2 54 placed on the side block 44 retracts with the side block 44 and stops blocking the blocking block 1 53, and the elastic force of the spring 2 48 is used to pull the sliding sleeve 1 46 to move, so as to drive the assembly plate 41 to retract into the assembly seat 4, and the semiconductor component 42 to be inspected mounted on the top of the assembly plate 41 is retracted into the assembly seat 4;
[0046] When the assembly box 3 moves upward, the semiconductor component 42 to be inspected that has been inspected at the top is retracted into the assembly seat 4, and the next semiconductor component 42 to be inspected is moved to the top position again for inspection.
[0047] like Figures 1 to 11As shown, a movable rod 552 is provided at the top and bottom ends of the side block 44, one end of the movable rod 552 is fixed with a connecting block 2 551, the connecting block 2 551 is fixed on the sliding sleeve 2 55, the other end of the movable rod 552 is sleeved with a connecting block 3 553 on the outside, the connecting block 3 553 is fixed on the sliding rod 2 56, a spring 4 554 is wound around the outside of the movable rod 552, one end of the spring 4 554 is fixedly connected to the connecting block 2 551, and the other end of the spring 4 554 is fixedly connected to the connecting block 3 553.
[0048] When the push block 1 51 pushes the push block 2 52 to drive the side block 44 to move, the sliding sleeve 2 55 slides outside the sliding rod 2 56, the sliding sleeve 2 55 drives the connecting block 2 551 and the movable rod 552 to move, the movable rod 552 slides in the connecting block 3 553, the connecting block 2 551 squeezes the spring 4 554 to shrink it, when the push block 1 51 finishes pushing the push block 2 52 and moves to the bottom of the push block 2 52, the push block 1 51 gradually loses the pressure on the push block 2 52, the spring 4 554 uses its own elastic force to push the connecting block 2 551 to move, under the action of the spring 4 554, the sliding sleeve 2 55 slides outside the sliding rod 2 56, the side block 44 follows the sliding sleeve 2 55 to move back to the initial position, and the blocking block 2 54 set on the side block 44 is reset;
[0049] It should be noted that the second blocking block 54 plays a blocking role. When the assembly disk 41 is removed from the assembly seat 4 to install the semiconductor component 42 to be tested, the straight portion of the second blocking block 54 is pressed against the straight portion of the first blocking block 53. The second blocking block 54 keeps the assembly disk 41 in the state of being removed from the assembly seat 4 through the first blocking block 53. In this state, the semiconductor component 42 to be tested can be installed and tested.
[0050] Secondly, the retraction of the blocking block 2 54 itself is that the assembly plate 41 is moved out of the assembly seat 4, the inclined surface of the blocking block 1 53 contacts the inclined surface of the blocking block 2 54, and the blocking block 2 54 is pushed into the side block 44 by the inclined surface of the blocking block 1 53, and after the blocking block 1 53 moves from the position of the blocking block 2 54, the blocking block 2 54 is reset, and the straight portion of the blocking block 1 53 contacts the straight portion of the blocking block 1 53 to block the blocking block 1 53;
[0051] Finally, the side block 44 as a whole drives the blocking block 2 54 to move backward, which is achieved by the pushing block 1 51 pushing the pushing block 2 52, so that after the semiconductor component 42 to be inspected is inspected, the inspected semiconductor component 42 to be inspected is moved into the assembly seat 4, and the semiconductor component 42 to be inspected at the next station can be moved to the inspection position again, and the inspected semiconductor component 42 to be inspected will not collide with the laser detection component 6 due to its own upward movement.
[0052] like Figures 1 to 11As shown, a slide rail 62 is provided at the front and rear ends of the laser detection component 6, an electric slider 61 is provided on the slide rail 62, the electric slider 61 is fixed to the front and back of the laser detection component 6, a slide rail 64 is provided on one side of the slide rail 62, the slide rail 64 is installed on one side of the detection box 1, an electric slider 63 is provided on the slide rail 64, and one side of the electric slider 63 is fixedly connected to the slide rail 62.
[0053] The electric slider 61 and the slide rail 62 are used to enable the laser detection component 6 to move horizontally above the semiconductor component 42 to be detected. The electric slider 63 and the slide rail 64 are used to enable the laser detection component 6 to move vertically above the semiconductor component 42 to be detected. The laser detection component 6 moves above the semiconductor component 42 to be detected to detect various parts of the semiconductor component 42 to be detected.
[0054] like Figures 1 to 11 As shown, a box seat 2 is fixed to the bottom of the detection box 1, an assembly table 31 is fixed to the bottom of the assembly box 3, an assembly table 32 is arranged at the bottom of the assembly table 31, and the assembly table 32 is fixed to the bottom end of the inside of the detection box 1, and a telescopic rod 33 is installed at the top end of the inside of the box seat 2, and the top of the telescopic rod 33 protrudes from the bottom end of the inside of the detection box 1 and is fixedly connected to the bottom of the assembly table 32.
[0055] The assembly platform 1 31 at the bottom of the assembly box 3 is installed on the assembly platform 2 32. When the assembly box 3 needs to be moved up, the assembly platform 2 32 is pushed up by the telescopic rod 33 to drive the assembly platform 1 31 to move up, so that the assembly box 3 can be moved up with it.
[0056] like Figures 1 to 11 As shown, connecting blocks 1 34 are fixed on both sides of the top of the second assembly platform 32, and connecting grooves 35 are opened on both sides of the bottom of the first assembly platform 31. The sizes of the connecting block 1 34 and the connecting groove 35 match, and the connecting groove 35 can slide on the outside of the connecting block 1 34.
[0057] Push out multiple assembly trays 41 from the assembly seat 4, and install the semiconductor components 42 to be tested on the assembly trays 41. By aligning the connecting grooves 35 on both sides of the bottom of the assembly platform 1 31 with the connecting blocks 1 34 on both sides of the top of the assembly platform 2 32, and sliding the connecting grooves 35 to the outside of the connecting blocks 1 34, the assembly platform 1 31 and the assembly platform 2 32 can be connected. The assembly box 3 is installed on the assembly platform 2 32 to complete the loading operation of multiple semiconductor components 42 to be tested.
[0058] like Figures 1 to 11As shown, a fixing hole 341 is provided at one end of the connecting block 34, and built-in cavities 342 are provided on both sides of the assembly table 31. The built-in cavity 342 is communicated with the interior of the connecting groove 35, and the position corresponds to the fixing hole 341. A fixing pin 343 is provided in the built-in cavity 342, and the fixing pin 343 can be inserted into the fixing hole 341.

[0059] When connecting the assembly platform 1 31 with the assembly platform 2 32, first pull the fixing pin 343 out of the connecting groove 35 to prevent the fixing pin 343 from blocking the connecting block 1 34 from sliding into the connecting groove 35. When pulling the fixing pin 343, the built-in block 344 moves with it and squeezes the spring 1 345 in the built-in cavity 342. When the connecting block 1 34 completely slides into the connecting groove 35, the fixing hole 341 and the fixing pin 343 are aligned. Release the pulled fixing pin 343, and the spring 1 345 drives the fixing pin 343 to be inserted into the fixing hole 341 by pushing the built-in block 344, thereby fixing the connection between the connecting block 1 34 and the connecting groove 35. In this way, the connection between the assembly platform 1 31 and the assembly platform 2 32 can be completed, so that the assembly box 3 can be loaded into the equipment for warpage detection.
[0060] By loading multiple semiconductor components 42 to be inspected at one time, the equipment can inspect multiple semiconductor components 42 to be inspected during inspection, without repeatedly clamping the semiconductor components 42 to be inspected. During the inspection process, the next batch of semiconductor components 42 to be inspected can be loaded.
