Description

Technical Field

[0001] This application relates to the field of integrated circuit visual inspection technology, and in particular to an integrated circuit inspection device. Background Technology

[0002] When performing visual inspection on integrated circuits such as central processing units, graphics processing units, memory, and power chips, a camera is first used to detect whether there are defects in the integrated circuits on the carrier tape. Then, a vacuum nozzle is used to remove the defective integrated circuits from the carrier tape and drop them into the waste box.

[0003] The existing technical solutions described above have the following drawbacks: Defective integrated circuits are stacked disorderly in the waste bin, causing wear and tear between them, which can easily lead to secondary damage to the integrated circuits and render even slightly defective integrated circuits completely unusable. Furthermore, the disorderly stacking of defective integrated circuits in the waste bin makes recycling and reuse of these integrated circuits quite difficult. Summary of the Invention

[0004] To prevent defective integrated circuits from suffering secondary damage and to reduce the difficulty of recycling and reusing integrated circuits, this application provides an integrated circuit testing device.

The rejection mechanism, located between the receiving mechanism and the feeding mechanism, drives the conveyor belt to remove defective integrated circuits from the carrier belt.

[0006] By employing the above technical solution, a vision inspection mechanism detects defects in the integrated circuits (ICs) on the carrier tape as it moves along the channel. For defective ICs, a rejection mechanism uses adhesive tape to detach them from the carrier tape. This ensures that the defective ICs are arranged in an orderly manner on the tape, maintaining a consistent orientation and preventing disordered stacking, thus avoiding secondary damage and reducing the scrap rate.

[0015] This application further includes: The housing is installed outside the supporting mechanism, feeding mechanism, receiving mechanism, conveying mechanism, visual inspection mechanism, and rejection mechanism.

[0016] In summary, the beneficial technical effects of this application are as follows: 1. A support mechanism forms a channel through which the feed tape passes. A feeding mechanism supplies the feed tape to the support mechanism. A take-up mechanism winds up the feed tape from the support mechanism. A conveying mechanism moves the feed tape along the channel. During the movement of the feed tape along the channel, a vision inspection mechanism detects defects in the integrated circuits on the carrier tape. For defective integrated circuits, a rejection mechanism uses adhesive tape to remove them from the carrier tape. This ensures that the defective integrated circuits are arranged in an orderly manner on the adhesive tape, maintaining a consistent orientation, avoiding disorderly stacking, and thus preventing secondary damage and reducing the scrap rate. Simultaneously, it facilitates secondary processing of the defective integrated circuits, effectively reducing the difficulty of recycling and reusing them.

[0017] 2. When the vision inspection mechanism detects a defect in one or more integrated circuits on the top surface of the carrier tape, the pressing component moves the tape downwards in a localized area, using the adhesive layer on the tape to detach the defective integrated circuit from the carrier tape and attach it to the tape. Then, the first rotary driver drives the first take-up reel to rotate, winding up the tape with the attached integrated circuit. The first linear module can drive the first moving base to move along the Y-axis, thereby moving the second linear module, the second moving base, the first unwind reel, the first take-up reel, the pressing component, and the tape along the Y-axis. The second linear module can drive the second moving base to move along the X-axis, thereby moving the first unwind reel, the first take-up reel, the pressing component, and the tape along the X-axis. In this way, the position of the tape can be adjusted in both the X and Y axes to pick up integrated circuits in different positions, ensuring both picking efficiency and picking accuracy.

[0018] 3. The first linear actuator drives the lifting platform downwards, which in turn moves the top plate, airbag, bottom plate, spring, and second pressing rod downwards via the first pressing rod, thus pressing down the adhesive tape and bringing the adhesive layer of the tape into contact with the defective integrated circuit. Then, the second linear actuator drives the lifting platform upwards, which in turn moves the top plate, airbag, bottom plate, spring, and second pressing rod upwards via the first pressing rod, thus moving the integrated circuit upwards with the tape. Gas can be injected into or released from the airbag via an air nozzle to adjust the airbag's stiffness. This ensures good contact between the tape and the integrated circuit, guaranteeing effective removal, while preventing excessive force on the integrated circuit during removal, thus avoiding secondary damage. The limiting screw and the limiting part cooperate to limit the maximum downward movement of the lifting platform, preventing severe compression of the integrated circuit. Furthermore, the height of the top surface of the limiting screw can be adjusted according to the thickness of the integrated circuit, allowing for adjustment of the maximum downward movement of the lifting platform, effectively improving the versatility of the pressing components and preventing secondary damage to the integrated circuit.

[0019] 4. The position of the locking lever can be adjusted by adjusting the position of the traction block, so that the middle part of the locking lever is in contact with the brake wheel or no longer in contact. When the middle part of the locking lever is in contact with the brake wheel, it can restrict the rotation of the brake wheel, thereby restricting the rotation of the shaft and the first unwinding reel. When the middle part of the locking lever is no longer in contact with the brake wheel, it can release the restriction on the brake wheel, allowing the shaft and the first unwinding reel to rotate.

[0022] It should be noted in advance that, if Figure 1 As shown, the existing tape 200 includes a carrier tape 210 and multiple integrated circuits 220. The multiple integrated circuits 220 are all attached to the carrier tape 210 and are distributed in multiple rows and columns.

[0023] The following is in conjunction with the appendix Figure 2-15 This application will be described in further detail.

[0024] Reference Figure 2 and Figure 3 This application discloses an integrated circuit testing device, including a support mechanism 110, a feeding mechanism 120, a receiving mechanism 130, a conveying mechanism 140, a vision inspection mechanism 150, and a rejection mechanism 160. The support mechanism 110 forms a channel through which a feeding tape 200 passes. The feeding mechanism 120 is disposed at one end of the support mechanism 110 and is used to supply the feeding tape 200 to the support mechanism 110. The receiving mechanism 130 is disposed at the other end of the support mechanism 110 and is used to wind up the feeding tape 200 from the support mechanism 110. The conveying mechanism 140 is mounted on the support mechanism 110 and is used to move the feeding tape 200 along the channel. The vision inspection mechanism 150 is disposed between the receiving mechanism 130 and the feeding mechanism 120 and is used to detect whether there are defects in the integrated circuit 220 on the carrier tape 210. A rejection mechanism 160 is positioned between the receiving mechanism 130 and the feeding mechanism 120, driving the conveyor belt 300 to detach defective integrated circuits 220 from the carrier belt 210. As the conveyor belt 200 moves along the channel, a vision inspection mechanism 150 detects defects in the integrated circuits 220 on the carrier belt 210. For defective integrated circuits 220, the rejection mechanism 160 uses the conveyor belt 300 to detach them from the carrier belt 210. This ensures that the defective integrated circuits 220 are arranged in an orderly manner on the conveyor belt 300, maintaining a consistent orientation, preventing disorderly stacking and thus avoiding secondary damage and reducing the scrap rate. Simultaneously, it facilitates secondary processing of the defective integrated circuits 220, effectively reducing the difficulty of recycling and reusing them.

[0025] Reference Figure 3 and Figure 4In one embodiment, the rejection mechanism 160 includes a first linear module 161, a first movable seat 162, a second linear module 163, a second movable seat 164, a first unwinding reel 1651, a first take-up reel 1652, a first rotary driver 1653, a first reversing wheel 1661, a second reversing wheel 1662, a third reversing wheel 1663, a fourth reversing wheel 1664, a fifth reversing wheel 1665, and a pressing assembly 167. The first linear module 161 is disposed on one side of the supporting mechanism 110 and extends along the Y-axis. The first movable seat 162 is disposed on one side of the supporting mechanism 110, and its bottom end is fixedly connected to the slide of the first linear module 161. The first linear module 161 drives the first movable seat 162 to move along the Y-axis. The second linear module 163 is mounted on the first movable seat 162 and extends along the X-axis. The second movable seat 164 is fixedly connected to the slide of the second linear module 163. The second linear module 163 drives the second movable seat 164 to move along the X-axis. A first unwind reel 1651 is rotatably mounted on the second movable seat 164 for releasing the tape 300. A first take-up reel 1652 is rotatably mounted on the second movable seat 164 for winding the tape 300. A first rotary driver 1653 is mounted on the second movable seat 164, and its output shaft is fixedly connected to the first take-up reel 1652 for driving the first take-up reel 1652 to rotate. A first reversing wheel 1661 is rotatably mounted on the lower part of the second movable seat 164. A second reversing wheel 1662 is rotatably mounted on the bottom of the second movable seat 164. A third reversing wheel 1663 is rotatably mounted on the bottom of the second movable seat 164. A fourth reversing wheel 1664 is rotatably mounted on the lower part of the second movable seat 164. A fifth reversing wheel 1665 is rotatably mounted on the upper part of the second movable seat 164. The tape 300 from the first unwind reel 1651 passes sequentially through the first reversing roller 1661, the second reversing roller 1662, the third reversing roller 1663, the fourth reversing roller 1664, and the fifth reversing roller 1665 before being wound onto the first take-up reel 1652. The pressing assembly 167 is mounted on the bottom of the second movable seat 164 and located between the third reversing roller 1663 and the second reversing roller 1662. It is used to move the adhesive layer of the tape 300 toward or away from the support mechanism 110, thereby causing the defective integrated circuit 220 to detach from the carrier tape 210 and adhere to the tape 300.

[0026] The working process and principle of the rejection mechanism 160 are as follows: When the visual inspection mechanism 150 detects a defect in one or more integrated circuits 220 on the top surface of the carrier tape 210, the pressing component 167 causes a local downward movement of the tape 300, using the adhesive layer on the tape 300 to detach the defective integrated circuit 220 from the carrier tape 210 and attach it to the tape 300. Then, the first rotary driver 1653 drives the first take-up reel 1652 to rotate, so as to take up the tape 300 with the integrated circuit 220 attached. The first linear module 161 can drive the first moving seat 162 to move along the Y-axis direction, so as to drive the second linear module 163, the second moving seat 164, the first unwinding reel 1651, the first take-up reel 1652, the pressing component 167 and the tape 300 to move along the Y-axis direction. The second linear module 163 can drive the second movable seat 164 to move along the X-axis, thereby moving the first unwinding reel 1651, the first take-up reel 1652, the pressing assembly 167, and the tape 300 along the X-axis. This allows the position of the tape 300 to be adjusted in both the X and Y axes to pick up integrated circuits 220 at different positions, ensuring both picking efficiency and accuracy.

[0027] Preferably, the second reversing wheel 1662 is movably mounted on the bottom of the second movable base 164. The third reversing wheel 1663 is movably mounted on the bottom of the second movable base 164. Thus, by adjusting the vertical height of the second reversing wheel 1662 and the third reversing wheel 1663, the tension of the tape 300 can be adjusted, thereby improving the tape removal effect. Specifically, an adjustment hole is formed at the bottom of the second movable base 164, and one end of the second reversing wheel 1662 and the third reversing wheel 1663 are respectively connected to the second movable base 164 through the adjustment hole. The adjustment hole allows the vertical position of the second reversing wheel 1662 / third reversing wheel 1663 to be adjusted.

[0028] Preferably, the first rotary driver 1653 can be a servo motor, which has high motion accuracy. The first rotary driver 1653 can also be a stepper motor, which has lower cost.

[0029] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7In one embodiment, the pressing assembly 167 includes a lifting seat 1671, a first linear actuator 1672, a top plate 1673, an airbag 1674, a bottom plate 1675, a waist ring 1676, a spring 1677, a second pressing rod 1678, a first fixing plate 16791, and a limiting screw 16792. The lifting seat 1671 is movably mounted on the bottom of the second movable seat 164, and the bottom has a first pressing rod 16711 formed thereon. The first linear actuator 1672 is mounted on the bottom of the second movable seat 164, and its output shaft is fixedly connected to the lifting seat 1671 for driving the lifting seat 1671 to move up and down. The top plate 1673 is fixedly connected to the bottom end of the first pressing rod 16711. An air nozzle 16731 ​​is formed on the top plate 1673. The axis of the airbag 1674 is vertically arranged, and its top end is fixedly connected to the top plate 1673. The base plate 1675 is fixedly connected to the bottom end of the airbag 1674. A waist ring 1676 is fitted over the airbag 1674 to limit the radial deformation of the airbag 1674. A spring 1677 passes through the airbag 1674, its top end fixedly connected to the top plate 1673, and its bottom end fixedly connected to the base plate 1675. A second pressing rod 1678 is vertically positioned, its top end fixedly connected to the base plate 1675, and its bottom end pressing against the tape 300. First, the first linear actuator 1672 drives the lifting seat 1671 to move downwards, which in turn drives the top plate 1673, airbag 1674, base plate 1675, spring 1677, and second pressing rod 1678 to move downwards, thereby pressing down the tape 300 and bringing the adhesive layer of the tape 300 into contact with the defective integrated circuit 220. Subsequently, the second linear actuator 1184 drives the lifting seat 1671 to move upward, which in turn drives the top plate 1673, airbag 1674, bottom plate 1675, spring 1677, and second pressing rod 1678 to move upward, thereby causing the integrated circuit 220 to move upward with the tape 300. Gas can be introduced into or released from the airbag 1674 through the air nozzle 16731 ​​to adjust the stiffness of the airbag 1674. This ensures good contact between the tape 300 and the integrated circuit 220, thus guaranteeing the adhesive removal effect, while also preventing excessive force from being applied to the integrated circuit 220 during the removal process, thereby avoiding secondary damage to the integrated circuit 220. A restrictive portion 16712 is formed on the top of the lifting seat 1671. The pressing assembly 167 also includes a first fixing plate 16791 and a limiting screw 16792. The first fixing plate 16791 is mounted on the bottom of the second moving seat 164. The limiting screw 16792 has a vertically oriented axis and is rotatably mounted on the first fixed plate 16791. Its top end can abut against the bottom end of the restricted part 16712. The limiting screw 16792 and the restricted part 16712 cooperate with each other to limit the maximum downward movement of the lifting seat 1671, thus preventing the integrated circuit 220 from being severely squeezed.Furthermore, based on the thickness of the integrated circuit 220, the height of the top surface of the limiting screw 16792 can be adjusted by rotating the limiting screw 16792, allowing the maximum downward movement of the lifting seat 1671 to be adjusted. This effectively improves the versatility of the pressing component 167 and prevents secondary damage to the integrated circuit 220. One end of the second reversing wheel 1662 has an air inlet 16621, the interior of its sidewall has a gas flow cavity 16622, and the outer wall has multiple air outlets 16623, each communicating with the gas flow cavity 16622. One end of the third reversing wheel 1663 has an air inlet 16621, the interior of its sidewall has a gas flow cavity 16622, and the outer wall has multiple air outlets 16623, each communicating with the gas flow cavity 16622. Gas is introduced into the gas flow chamber 16622 through the air inlet 16621, and the gas flows out through the air outlet 16623. The gas flow through the gas flow chamber 16622 and agitates the surface of the conveyor belt 300, causing the conveyor belt 300 to float on the outer walls of the second reversing wheel 1662 and the third reversing wheel 1663. This reduces the wear between the conveyor belt 300 and the second / third reversing wheel 1662 and 1663, and also allows the direction of the conveyor belt 300 to better match the position of the second pressure rod 1678.

[0030] Preferably, the first linear actuator 1672 is a cylinder, hydraulic cylinder, or electric actuator, etc.

[0031] Reference Figure 8 and Figure 9 In one embodiment, the first unwinding reel 1651 is rotatably connected to the top of the second movable seat 164 via a rotating shaft. The rejection mechanism 160 also includes a brake wheel 1681, a second fixed plate 1682, a traction block 1683, a locking pin (not shown), and a locking lever 1684. The brake wheel 1681 is sleeved on the rotating shaft. The second fixed plate 1682 is mounted on the top of the second movable seat 164. A locking hole is formed in the second fixed plate 1682. An adjustment hole 16831 is formed in the traction block 1683. The locking pin connects the traction block 1683 and the second fixed plate 1682 through the adjustment hole 16831 and the locking hole. The middle portion of the locking lever 1684 passes around the brake wheel 1681, and its opposite ends are fixedly connected to the traction block 1683. The position of the locking rod 1684 can be adjusted by adjusting the position of the traction block 1683, so that the middle part of the locking rod 1684 is in contact with or no longer in contact with the brake wheel 1681. When the middle part of the locking rod 1684 is in contact with the brake wheel 1681, the rotation of the brake wheel 1681 can be restricted, thereby restricting the rotation of the shaft and the first unwinding reel 1651. When the middle part of the locking rod 1684 is no longer in contact with the brake wheel 1681, the restriction on the brake wheel 1681 can be released, allowing the shaft and the first unwinding reel 1651 to rotate.

[0032] Reference Figure 3 , Figure 4 and Figure 10 In one embodiment, the rejection mechanism 160 further includes a first backlight 1691, two first sidelights 1692, a first coaxial light source 1693, and a first camera 1694. The first backlight 1691 is movably mounted on the bottom of the second movable base 164, moving with the second movable base 164, and emits light towards the top surface of the supporting mechanism 110. The two first sidelights 1692 are movably positioned below the supporting mechanism 110, respectively, and emit light towards the bottom surface of the supporting mechanism 110. The first coaxial light source 1693 is movably positioned below the two first sidelights 1692. The first camera 1694 has a vertically oriented axis and an upward-facing lens, and is movably positioned below the first coaxial light source 1693. The first camera 1694 is used to acquire images below the conveyor belt 200. The first backlight 1691 emits light onto the top surface of the strip 200, creating a transmitted light effect. For transparent / semi-transparent products, this clearly reveals internal defects such as cracks and bubbles. For opaque products, it highlights edge features through contour lighting, facilitating positioning by the first camera 1694. Two tilted first sidelights 1692 illuminate the product from below the support mechanism 110, using diffused light to illuminate three-dimensional features such as recesses, steps, and textures on the product's sides, avoiding shadow blind spots caused by a single vertical light source. The first coaxial light source 1693 effectively reduces interference from surface reflections, allowing fine defects such as scratches and dents to be clearly visible, improving the accuracy of visual inspection. The first backlight 1691, the two first sidelights 1692, the first coaxial light source 1693, and the first camera 1694 work together to perform both visual inspection and positioning of the bottom surface of the integrated circuit 220, assisting the tape 300 in accurately removing defective integrated circuits 220. Based on the size, material, and detection characteristics of the integrated circuit 220, the height of each light source and the shooting distance can be flexibly adjusted. When the integrated circuit 220 is thin, the intensity of transmitted light can be enhanced by lowering the height of the first backlight 1691. When the surface of the integrated circuit 220 has strong reflection, the incident angle of the light can be optimized by adjusting the height of the first coaxial light source 1693. For side defects of the integrated circuit 220 at different tilt angles, the incident angle of the light can be adjusted by adjusting the height of the two first side light sources 1692 in the vertical direction, ensuring the best supplementary lighting effect and further improving the identification of defects.

[0033] Preferably, adjustment holes are formed on the first backlight 1691, the two first sidelights 1692, the first coaxial light source 1693, and the first camera 1694, and the adjustment holes allow the vertical positions of the first backlight 1691, the two first sidelights 1692, the first coaxial light source 1693, and the first camera 1694 to be adjustable.

[0034] Reference Figure 11 and Figure 12In one embodiment, the supporting mechanism 110 includes a first bracket 111, a second bracket 112, a supporting plate 113, a first light-transmitting plate 114, a second light-transmitting plate 115, a first stop bar 116, and a second stop bar 117. The first bracket 111 is disposed near the feeding mechanism 120. The second bracket 112 is disposed near the receiving mechanism 130. One end of the supporting plate 113 is fixedly connected to the first bracket 111, and the other end is fixedly connected to the second bracket 112. A first clearance hole 1131 and a second clearance hole 1132 are formed on the supporting plate 113. The first light-transmitting plate 114 is installed in the first clearance hole 1131. The second light-transmitting plate 115 is installed in the second clearance hole 1132. The first stop bar 116 is fixed to one side of the top surface of the supporting plate 113. The second stop bar 117 is movably mounted on the other side of the top surface of the supporting plate 113, facing or away from the first stop bar 116. A channel is formed between the adjacent sides of the second stop 117 and the first stop 116. The width of the channel is adjusted by moving the second stop 117 toward or away from the first stop 116, so that the width of the channel matches the width of the conveyor belt 200. This effectively improves the versatility of the support mechanism 110. Multiple suction holes 1133 are formed on the support plate 113. The suction holes 1133 can communicate with a negative pressure generating device. The suction holes 1133 allow the bottom surface of the conveyor belt 200 to adhere well to the top surface of the support plate 113. This improves the accuracy of the detection results and facilitates the removal of defective integrated circuits 220. The support mechanism 110 also includes multiple third fixing plates 1181, multiple pressure plates 1182, multiple buffer pads 1183, and multiple second linear actuators 1184. At least one is fixed to the top surface of the first stop 116, and at least one is fixed to the top surface of the second stop 117. Multiple pressure plates 1182 are slidably mounted on the third fixed plates 1181 in a one-to-one correspondence. One end of each pressure plate 1182 is bent downward to form a pressure part 11821. Multiple buffer pads 1183 are fixed to the bottom surface of the pressure part 11821 in a one-to-one correspondence with the multiple pressure plates 1182. Multiple second linear actuators 1184 are fixed to the third fixed plates 1181 in a one-to-one correspondence. The output shafts of the multiple second linear actuators 1184 are fixedly connected to the multiple pressure plates 1182 in a one-to-one correspondence, and are used to drive the corresponding pressure plate 1182 to move up and down. When it is necessary to remove a defective integrated circuit 220, multiple second linear actuators 1184 respectively drive the corresponding pressure plates 1182 to move downwards, so that the pressure portions 11821 of the multiple pressure plates 1182 press against the top surface of the carrier tape 210, which facilitates the smooth removal of the defective integrated circuit 220 from the carrier tape 210. The buffer pad 1183 plays a buffering role, reducing the impact force on the carrier tape 210 and preventing damage to the carrier tape 210.

[0035] Preferably, the second stop 117 is connected to the top surface of the support plate 113 through an adjustment hole so that the position of the second stop 117 can be adjusted.

[0036] Preferably, each second linear actuator 1184 is a cylinder, hydraulic cylinder, or electric actuator, etc.

[0037] Reference Figure 11 and Figure 13In one embodiment, the conveying mechanism 140 includes a feeding roller 141, a second rotary driver 142, a support rod 143, multiple pressure rollers 144, two lead screws 145, two lifting blocks 146, two locking nuts 148, two adjusting sleeves 1491, and two compression springs 1492. The feeding roller 141 is rotatably mounted on the second bracket 112, with its sidewall abutting against one side of the carrier belt 210. The second rotary driver 142 is mounted on the second bracket 112, and its output shaft is fixedly connected to one end of the feeding roller 141 to drive the feeding roller 141 to rotate. The support rod 143 is disposed above the feeding roller 141, and its axis is parallel to the axis of the feeding roller 141. The multiple pressure rollers 144 are rotatably sleeved on the support rod 143 via bearings, and their sidewalls abut against the other side of the carrier belt 210. The second rotary driver 142 drives the feeding roller 141 to rotate. The rotating feeding roller 141 cooperates with multiple pressure rollers 144, causing the material belt 200 to move along the channel. The axes of the two lead screws 145 are both vertically arranged and rotatably mounted on opposite sides of the second bracket 112. One lifting block 146 is mounted on one lead screw 145 via one lead screw nut 147 and fixedly connected to one end of the support rod 143. The other lifting block 146 is mounted on the other lead screw 145 via another lead screw nut 147 and fixedly connected to the other end of the support rod 143. By rotating the two lead screws 145, the vertical height of the corresponding lifting block 146 can be adjusted, thereby adjusting the vertical height of the support rod 143, thus adjusting the downward pressure effect of the multiple pressure rollers 144, and consequently adjusting the conveying speed. Two locking nuts 148 are screwed onto two lead screws 145 in a one-to-one correspondence. Their bottom ends abut against the top of the second bracket 112, limiting the spontaneous rotation of the corresponding lead screws 145 and ensuring the stability of the positions of the two lifting blocks 146, thereby ensuring the stability of the positions of the support rod 143 and the pressure roller 144. When the bottom ends of both locking nuts 148 are disengaged from the top of the second bracket 112, the two lead screws 145 can rotate. Two adjusting sleeves 1491 are screwed onto the lead screws 145 in a one-to-one correspondence. Two compression springs 1492 are sleeved onto the lead screws 145 in a one-to-one correspondence. Their top ends abut against the bottom ends of the two adjusting sleeves 1491 in a one-to-one correspondence, and their bottom ends abut against the top ends of the two lifting blocks 146 in a one-to-one correspondence. The compression springs 1492 provide elastic cushioning. When there is a thickness deviation in the carrier belt 210, the compression spring 1492 can automatically extend and retract to compensate, ensuring that the pressure of the pressure roller 144 on the carrier belt 210 remains stable, thus preventing slippage or damage to the carrier belt 210 caused by uneven thickness. At the same time, the compression spring 1492 can also absorb vibrations generated during the conveying process, further improving the smoothness of the conveying.

[0038] Preferably, the second rotary driver 142 can be a servo motor, which has high motion accuracy. Alternatively, the second rotary driver 142 can be a stepper motor, which has lower cost.

[0039] Reference Figure 3 and Figure 14In one embodiment, the visual inspection mechanism 150 includes a third support 151, a third linear module 152, a third movable base 153, a second camera 154, a second coaxial light source 155, two second side light sources 156, and a second backlight 157. The third support 151 is disposed on one side of the support mechanism 110 and supports the third linear module 152, the third movable base 153, the second camera 154, the second coaxial light source 155, and the two second side light sources 156. The third linear module 152 is mounted on the top of the third support 151 and extends along the X-axis. The third movable base 153 is fixedly connected to the slide of the third linear module 152. The third linear module 152 drives the third movable base 153 to move along the X-axis. The second camera 154 is vertically oriented with its lens facing downwards and is movably mounted on the third movable base 153. The second coaxial light source 155 is movably mounted on the third movable base 153 and is located below the second camera 154. Two second side light sources 156 are mounted vertically on the third movable base 153, both located below the second coaxial light source 155, and can emit light towards the top surface of the support mechanism 110. A second backlight source 157 is positioned below the support mechanism 110 and can emit light towards the bottom surface of the support mechanism 110. A second camera 154 is used to capture images above the conveyor belt 200. The second backlight source 157 emits light towards the bottom surface of the conveyor belt 200, creating a transmitted light effect. For transparent / semi-transparent products, this clearly reveals internal defects such as cracks and bubbles. For opaque products, it can also highlight edge features through contour lighting, facilitating positioning by the second camera 154. The two tilted second side light sources 156 illuminate obliquely from above the support mechanism 110, using diffused light to illuminate three-dimensional features such as recesses, steps, and textures on the sides of the product, avoiding shadow blind spots caused by a single vertical light source. The second coaxial light source 155 effectively reduces interference from surface reflections, allowing fine defects such as scratches and dents to be clearly visible, thus improving the accuracy of visual inspection. The second backlight 157, two second side light sources 156, the second coaxial light source 155, and the second camera 154 work together to perform visual inspection of the top surface of the integrated circuit 220. The height and shooting distance of each light source can be flexibly adjusted according to the size, material, and inspection characteristics of the integrated circuit 220. The third linear module 152 drives the third moving base 153 to move along the X-axis, thereby moving the second camera 154, the second coaxial light source 155, and the two second side light sources 156 along the X-axis. This enables segmented scanning inspection and allows for the inspection of integrated circuits 220 in different positions at the same workstation without needing to readjust the product placement, greatly improving inspection flexibility.Meanwhile, the second camera 154, the second coaxial light source 155, and the two second side light sources 156 move synchronously, ensuring the stability of the relative position of the second camera 154 with the second coaxial light source 155 / second side light source 156, and improving the repeatability and consistency of the detection results.

[0040] Preferably, adjustment holes are formed on the second backlight 157, the two second sidelights 156, the second coaxial light source 155, and the second camera 154, so that the positions of the second backlight 157, the two second sidelights 156, the second coaxial light source 155, and the second camera 154 in the vertical direction can be adjusted.

The structure and working principle of the first unwinding assembly 121, the first winding assembly 122, the second unwinding assembly 131, and the second winding assembly 132 are existing technologies and will not be described in detail here.

[0042] Reference Figure 15 In one embodiment, the integrated circuit testing equipment further includes a housing 170 and a controller 180. The housing 170 covers the support mechanism 110, the feeding mechanism 120, the receiving mechanism 130, the conveying mechanism 140, the vision inspection mechanism 150, and the rejection mechanism 160, providing protection for these components and extending their service life. The controller 180 is mounted on the outer wall of the housing 170 and is electrically connected to the feeding mechanism 120, the receiving mechanism 130, the conveying mechanism 140, the vision inspection mechanism 150, and the rejection mechanism 160, respectively, for controlling their operation.

[0043] The implementation principle of this embodiment is as follows: The supporting mechanism 110 forms a channel through which the feed tape 200 passes. The feeding mechanism 120 is used to supply the feed tape 200 to the supporting mechanism 110. The take-up mechanism 130 is used to take up the feed tape 200 from the supporting mechanism 110. The conveying mechanism 140 is used to move the feed tape 200 along the channel. The vision inspection mechanism 150 is used to detect whether there are defects in the integrated circuits 220 on the carrier tape 210. The rejection mechanism 160 drives the tape 300 to rotate, using the tape 300 to remove the defective integrated circuits 220 from the carrier tape 210. During the movement of the feed tape 200 along the channel, the vision inspection mechanism 150 detects whether there are defects in the integrated circuits 220 on the carrier tape 210. For the defective integrated circuits 220, the rejection mechanism 160 uses the tape 300 to remove the defective integrated circuits 220 from the carrier tape 210. In this way, the defective integrated circuits 220 are arranged in an orderly manner on the tape 300, maintaining a generally consistent orientation. This avoids disorderly stacking of the defective integrated circuits 220, thereby preventing secondary damage and reducing the scrap rate. Simultaneously, it facilitates secondary processing of the defective integrated circuits 220, effectively reducing the difficulty of recycling and reusing them.

[0044] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
