[0070] Figure 1 A schematic structural diagram of a packaging auxiliary device in one embodiment of the present application is shown; Figure 2 It shows a product flow diagram of a packaging auxiliary device in one embodiment of the present application; Figure 3 A structural diagram of a detection mechanism in an embodiment of the present application is shown.

[0071] In some embodiments, see Figures 1 to 3 The present invention provides a packaging auxiliary device 100. The packaging auxiliary device 100 is sequentially arranged along a first direction (direction x in the figure), including a loading station A, an assembly station B, an inspection station C, and an unloading station D. The inspection station C is divided into a position to be inspected C1, a position to be inspected C2, and a position to be inspected C3 along the first direction. Specifically, the packaging auxiliary device 100 includes a frame 110, on which the aforementioned stations and the various mechanisms described below are disposed.

[0072] The packaging auxiliary device 100 includes a detection mechanism 120, a first feeding mechanism 130, and a second feeding mechanism 140. The detection mechanism 120 is located at the detection station C. The detection mechanism 120 includes a movable platform 122 and a detection assembly 121 located at the current measurement position C2. The movable platform 122 is configured to reciprocate along a first direction between the to-be-measured position C1, the current measurement position C2, and the measured position C3. The first feeding mechanism 130 is configured to reciprocate along a first direction between the loading station A, the assembly station B, and the to-be-measured position C1. The second feeding mechanism 140 is configured to reciprocate along the first direction between the measured position C3 and the unloading station D.

[0073] The first feeding mechanism 130 is located at the loading station A and is used to obtain the expansion ring 11. The first feeding mechanism 130 is located at the assembly station B and is used to assemble the obtained expansion ring 11 with the fixture 12 located at the assembly station B into the assembly 10. The first feeding mechanism 130 is located at the test position C1 and is used to place the assembly 10 on the movable carrier 122 located at the test position C1. The second feeding mechanism 140 is located at the measured position C3 and is used to obtain the assembly 10 from the movable carrier 122 located at the measured position C3. The second feeding mechanism 140 is located at the unloading station D and is used to place the assembly 10 on the unloading station D.

[0074] The detection component 121 is used for optical detection of chips, including a visual camera and a light source module, which can obtain the position and angle information of the chip, and can also be expanded to detect chip defects, etc., to facilitate chip screening. The first feeding mechanism 130 and the second feeding mechanism 140 can obtain the products on the preceding station in the first direction and place the products on the subsequent station. Optionally, the first feeding mechanism 130 and the second feeding mechanism 140 can use a robotic arm. In particular, the fixture 12 is provided with a mounting hole for accommodating the crystal expansion ring 11. The first feeding mechanism 130 places the crystal expansion ring 11 in the mounting hole of the fixture 12 to complete the assembly of the crystal expansion ring 11 and the fixture 12.

[0075] The working process of the packaging auxiliary device 100 is as follows: the first feeding mechanism 130 transfers the wafer expansion ring 11 from the loading station A to the assembly station B for assembly with the fixture 12, and then transfers the assembled assembly 10 from the assembly station B to the movable carrier 122 located at the test position C1. The movable carrier 122 moves the assembly 10 to the test position C2 and uses the detection component 121 to perform chip optical detection, and then moves the assembly 10 after detection from the test position C2 to the measured position C3. The second feeding mechanism 140 transfers the assembly 10 from the movable carrier 122 located at the measured position C3 to the unloading station D. The above-mentioned packaging auxiliary device 100 can realize the functions of wafer expansion ring loading and chip optical detection. The various workstations are arranged compactly. The transfer of products between different workstations is realized through the first feeding mechanism 130 and the second feeding mechanism 140. The movement of products between different positions of the detection station C is realized through the movable carrier 122. While realizing the flow of products, interference between different mechanisms is avoided, which helps to carry out each process efficiently and orderly, thereby simplifying the operation process and improving operation efficiency.

[0076] Figure 4 A structural schematic diagram of the first feeding mechanism in an embodiment of the present application is shown.

[0077] In some embodiments, see Figure 1 、 Figure 2 and Figure 4 The first feeding mechanism 130 includes a first lateral moving member 131, a first vertical moving member 132, and a first clamping member 133. The first lateral moving member 131 is connected to the first vertical moving member 132, and the first vertical moving member 132 is connected to the first clamping member 133. The first clamping member 133, the wafer expansion ring 11, and the clamp 12 are aligned in the second direction (the y direction in the figure). The first lateral moving member 131 is configured to drive the first vertical moving member 132 and the first clamping member 133 to reciprocate along the first direction (the x direction in the figure). The first vertical moving member 132 is configured to drive the first clamping member 133 to reciprocate along the third direction (the z direction in the figure). The first direction, the second direction, and the third direction are perpendicular to each other.

[0078] By mechanically or manually adjusting the placement position of the expansion ring 11 on the loading station A and the placement position of the clamp 12 on the assembly station B, the expansion ring 11 and the clamp 12 are aligned with the first clamp 133 in the second direction. In this way, the first feeding mechanism 130 only needs to be configured with automatic movement in the first direction and the third direction to achieve precise placement of the expansion ring 11, the clamp 12, and the assembly 10 formed by the two, which helps to reduce the difficulty of positioning and simplify the mechanical structure. Optionally, the first transverse moving member 131 and the first vertical moving member 132 can adopt linear transmission mechanisms such as electric push rods, electric cylinders, linear motors, and gear racks, and the first clamp 133 can adopt electric clamps or pneumatic clamps. Furthermore, the first clamp 133 can adopt a centering clamping structure to improve the accuracy of placement.

[0079] It should be noted that the first direction, the second direction and the third direction in the present application may correspond to the horizontal direction, the longitudinal direction and the vertical direction respectively.

[0080] In some embodiments, see Figure 1 and Figure 2 The packaging auxiliary device 100 further includes a first loading mechanism 150 and a second loading mechanism 160. The first loading mechanism 150 is located at the loading station A and is used to obtain the wafer expansion ring 11 from the first magazine (not shown) and align the wafer expansion ring 11 with the first clamping member 133 in the second direction. The second loading mechanism 160 is located at the assembly station B and is used to obtain the clamp 12 from the second magazine (not shown) and align the clamp 12 with the first clamping member 133 in the second direction. It can be understood that the first magazine is located at the loading station A and contains a plurality of wafer expansion rings 11. The second magazine is located at the assembly station B and contains a plurality of clamps 12. In this way, the first loading mechanism 150 is used to obtain the crystal expansion ring 11 in the first material box and place the crystal expansion ring 11 in a position aligned with the first clamping member 133 in the second direction. The second loading mechanism 160 is used to obtain the clamp 12 in the second material box and place the clamp 12 in a position aligned with the first clamping member 133 in the second direction. This can reduce manual participation, improve the degree of automation of the packaging auxiliary device 100, and thus improve work efficiency.

[0081] Figure 5 A schematic diagram showing a partial structure of a first feeding mechanism in one embodiment of the present application is shown; Figure 6 A schematic diagram showing a partial structure of the second feeding mechanism in one embodiment of the present application is shown.

[0082] In some embodiments, see Figure 2 and Figure 5The first loading mechanism 150 includes two first guide members 151, a second clamping member 152, and a first lifting member 153. The two first guide members 151 are spaced apart along the first direction, and each first guide member 151 is provided with a first slide groove 1511 extending along the second direction. The second clamping member 152 is located between the two first guide members 151 and is configured to clamp the expander ring 11 in the first magazine and move it in the second direction. The first lifting member 153 is configured to move the first magazine in the third direction, so that the expander ring 11 in the first magazine is aligned with the second clamping member 152 in the third direction.

[0083] The two first guide members 151 support the expanding ring 11 in the third direction and guide its movement in the second direction. With the continuous support and guidance of the first guide members 151, the second clamping member 152 only needs to apply traction and a small clamping force to the expanding ring 11 to achieve stable transfer of the expanding ring 11, preventing damage to the expanding ring 11 caused by excessive clamping force. Multiple expanding rings 11 are stacked in the first magazine along the third direction. The first lifting member 153 facilitates relative movement of the first magazine and the second clamping member 152 in the third direction, helping to reduce positioning difficulty and simplify the mechanical structure. Optionally, the first magazine can be a basket-type magazine, and the second clamping member 152 can be an electric or pneumatic clamp.

[0084] Specific to Figure 5 In the illustrated embodiment, the first loading mechanism 150 further includes a first longitudinal motion member 154, which is connected to the second clamping member 152. The first longitudinal motion member 154 is configured to drive the second clamping member 152 to reciprocate in a second direction, thereby enabling the second clamping member 152 to drive the wafer expanding ring 11 to move in the second direction. Alternatively, the first longitudinal motion member 154 may be a linear transmission mechanism such as an electric push rod, an electric cylinder, a linear motor, or a rack and pinion.

[0085] In some embodiments, see Figure 2 and Figure 6 The second loading mechanism 160 includes two second guide members 161, a third clamping member 162, and a second lifting member 163. The two second guide members 161 are spaced apart along the first direction, and each second guide member 161 is provided with a second slide 1611 extending along the second direction. The third clamping member 162 is located between the two second guide members 161 and is configured to clamp the clamp 12 in the second magazine and move the clamp 12 in the second direction. The second lifting member 163 is configured to move the second magazine in the third direction so that the clamp 12 in the second magazine is aligned with the third clamping member 162 in the third direction.

[0086] The two second guide members 161 support the clamp 12 in the third direction and guide its movement in the second direction. With the continuous support and guidance of the second guide members 161, the third clamping member 162 only needs to apply traction and a small clamping force to the clamp 12 to achieve stable transfer of the clamp 12, preventing damage to the clamp 12 caused by excessive clamping force. Multiple clamps 12 are stacked in the second magazine along the third direction, and the second lifting member 163 is used to achieve relative movement between the second magazine and the third clamping member 162 in the third direction, which helps to reduce positioning difficulty and simplify the mechanical structure. Optionally, the second magazine can be a basket-type magazine, and the third clamping member 162 can be an electric or pneumatic gripper.

[0087] Specific to Figure 6 In the illustrated embodiment, the second loading mechanism 160 further includes a second longitudinal motion member 164, which is connected to the third clamping member 162. The second longitudinal motion member 164 is configured to drive the third clamping member 162 to reciprocate in the second direction, thereby enabling the third clamping member 162 to drive the fixture 12 to move in the second direction. Alternatively, the second longitudinal motion member 164 may be a linear transmission mechanism such as an electric push rod, an electric cylinder, a linear motor, or a rack and pinion.

[0088] It should be noted that in some embodiments, the first loading mechanism 150 and the second loading mechanism 160 may adopt similar mechanical structures as in the illustrated embodiment (details may vary) to facilitate manufacturing and achieve synchronous control. Of course, in other embodiments, the first loading mechanism 150 and the second loading mechanism 160 may also adopt different mechanical structures, and this application is not limited to this.

[0089] In some embodiments, see Figure 5 and Figure 6 The first loading mechanism 150 further includes two first connecting plates 155 and a first base plate 156. Each first guide member 151 is connected to the first base plate 156 via a first connecting plate 155, and at least one first connecting plate 155 is slidably connected to the first base plate 156 along the first direction. The second loading mechanism 160 further includes two second connecting plates 165 and a second base plate 166. Each second guide member 161 is connected to the second base plate 166 via a second connecting plate 165, and at least one second connecting plate 165 is slidably connected to the second base plate 166 along the first direction. Thus, by sliding at least one first connecting plate 155 relative to the first base plate 156, the spacing between the two first guide members 151 in the first direction can be adjusted. By sliding at least one second connecting plate 165 relative to the second base plate 166, the spacing between the two second guide members 161 in the first direction can be adjusted. This allows the assembly to accommodate wafer expansion rings 11 and fixtures 12 of varying sizes, thereby improving the applicability of the packaging auxiliary device 100.

[0090] Figure 7 A structural schematic diagram of the second feeding mechanism in one embodiment of the present application is shown.

[0091] In some embodiments, see Figure 1 、 Figure 2 and Figure 7 The second feeding mechanism 140 includes a second lateral moving member 141, a second vertical moving member 142 and a fourth clamping member 143. The second lateral moving member 141 is connected to the second vertical moving member 142, and the second vertical moving member 142 is connected to the fourth clamping member 143. The fourth clamping member 143 and the assembly 10 (y direction in the figure) are aligned in the second direction. The second lateral moving member 141 is configured to drive the second vertical moving member 142 and the fourth clamping member 143 to reciprocate along the first direction (x direction in the figure). The second vertical moving member 142 is configured to drive the fourth clamping member 143 to reciprocate along the third direction (z direction in the figure). The first direction, the second direction and the third direction are perpendicular to each other.

[0092] By adjusting the placement position of the assembly 10 on the mobile platform 122 or by moving the mobile platform 122 itself, the assembly 10 on the mobile platform 122 is aligned with the fourth clamping member 143 in the second direction. In this way, the second feeding mechanism 140 only needs to be configured with the movement automation in the first direction and the third direction to achieve accurate pick-up and placement of the assembly 10, which helps to reduce the difficulty of positioning and simplify the mechanical structure. Optionally, the second lateral moving member 141 and the second vertical moving member 142 can adopt linear transmission mechanisms such as electric push rods, electric cylinders, linear motors, gear racks, etc., and the fourth clamping member 143 can adopt electric clamps or pneumatic clamps. Furthermore, the fourth clamping member 143 can adopt a centering clamping structure to improve the accuracy of pick-up and placement.

[0093] It should be noted that in some embodiments, the first feeding mechanism 130 and the second feeding mechanism 140 may adopt similar mechanical structures as in the illustrated embodiment (the details may vary) to facilitate manufacturing and achieve synchronous control. Of course, in other embodiments, the first feeding mechanism 130 and the second feeding mechanism 140 may also adopt different mechanical structures, and this application is not limited to this.

[0094] In some embodiments, see Figure 1 and Figure 2The packaging assistance device 100 further includes a feeding mechanism 170. This feeding mechanism 170 is located at the feeding station D and is used to move the assembly 10 along the second direction into the third magazine 20. It will be appreciated that the third magazine 20, located at the feeding station D, has multiple spaces for accommodating the assembly 10. Thus, by using the feeding mechanism 170 to transfer the assembly 10 from a position aligned with the second feeding mechanism 140 in the second direction to the third magazine 20, manual intervention can be reduced, the degree of automation of the packaging assistance device 100 can be increased, and thus operational efficiency can be improved.

[0095] Figure 8 A schematic diagram showing a partial structure of a blanking mechanism in an embodiment of the present application is shown.

[0096] In some embodiments, see Figure 2 and Figure 8 The unloading mechanism 170 includes two third guide members 171, a pusher 172, and a third lifter 173. The two third guide members 171 are spaced apart along the first direction, and each third guide member 171 is provided with a third slide 1711 extending along the second direction. The pusher 172 is located between the two third guide members 171 and is configured to abut against the assembly 10 and push it along the second direction into the empty space of the third magazine 20. The third lifter 173 is configured to move the third magazine 20 along the third direction so that the empty space of the third magazine 20 is aligned with the assembly 10 in the third direction.

[0097] The two third guide members 171 support the assembly 10 in the third direction and guide its movement in the second direction. With the continuous support and guidance of the third guide members 171, the material stripper only needs to apply a thrust to the assembly 10 to achieve stable transfer of the assembly 10, eliminating the need for clamping the assembly 10. This simplifies the structure and reduces energy consumption. Multiple spaces for accommodating the assembly 10 are stacked in the third magazine 20 along the third direction. The third lift member 173 facilitates relative movement between the third magazine 20 and the assembly 10 in the third direction, helping to reduce positioning difficulty and simplify the mechanical structure. Alternatively, the third magazine 20 can be a basket-type magazine.

[0098] Specific to Figure 8 In the illustrated embodiment, the unloading mechanism 170 further includes a third longitudinal motion member 174, which is connected to the pusher 172. The third longitudinal motion member 174 is configured to drive the pusher 172 to reciprocate in the second direction, thereby enabling the pusher 172 to push the assembly 10 in the second direction. Alternatively, the third longitudinal motion member 174 may be a linear transmission mechanism such as an electric push rod, an electric cylinder, a linear motor, or a rack and pinion.

[0099] In some embodiments, the unloading mechanism 170 further includes two third connecting plates 175 and a third base plate 176. Each third guide member 171 is connected to the third base plate 176 via a third connecting plate 175, and at least one third connecting plate 175 is slidably connected to the third base plate 176 along the first direction. Thus, by sliding at least one third connecting plate 175 relative to the third base plate 176, the spacing between the two third guide members 171 in the first direction can be adjusted, thereby accommodating assemblies 10 of varying sizes and specifications, thereby improving the applicability of the packaging assisting device 100.

[0100] Figure 9 A structural schematic diagram of another part of the blanking mechanism in one embodiment of the present application is shown.

[0101] In some embodiments, see Figure 9 The unloading mechanism 170 further includes a lifting drive 177 connected to the third lifting member 173. The lifting drive 177 is configured to drive the third lifting member 173 to reciprocate along the third direction, thereby enabling the third lifting member 173 to drive the third material box 20 to move along the third direction. Alternatively, the lifting drive 177 can be a linear transmission mechanism such as an electric push rod, an electric cylinder, a linear motor, or a gear rack, and the third lifting member 173 is configured as a support plate.

[0102] It can be understood that the first lifting member 153 of the first loading mechanism 150, the second lifting member 163 of the second loading mechanism 160 and the third lifting member 173 of the unloading mechanism 170 can adopt similar structures and driving methods, which will not be elaborated here.

[0103] In some embodiments, see Figure 2 and Figure 3 , the detection component 121 is fixed at the measurement position C2, and the movable carrier 122 is configured to be able to reciprocate along the second direction (y direction in the figure) perpendicular to the first direction (x direction in the figure). In this way, when performing optical inspection of the chip, the visual camera does not move, and the movable carrier 122 drives the assembly 10 to move along the first direction and the second direction, so that the inspection area can cover the entire wafer chip area. This form of detection avoids the visual system error caused by camera movement and has a higher detection accuracy. In addition, by configuring the movable carrier 122 to be able to reciprocate along the second direction, the movable carrier 122 can drive the assembly 10 to align with the fourth clamping member 143 of the second feeding mechanism 140 in the second direction, which helps to reduce the difficulty of positioning and simplify the mechanical structure.

[0104] In some embodiments, the detection mechanism 120 further includes an anti-vibration platform 123, on which the detection assembly 121 and the movable platform 122 are mounted, thereby preventing vibration from affecting the detection accuracy of the device. Optionally, the anti-vibration platform 123 may be a marble platform.

[0105] In some embodiments, the detection mechanism 120 further includes a clamping member 124, which is used to clamp the assembly 10 to the movable platform 122 to prevent the assembly 10 from slipping relative to the movable platform 122 when the movable platform 122 moves, thereby further ensuring detection accuracy. It will be understood that when the clamping member 124 clamps the assembly 10, it should not block the wafer chip area. Optionally, the clamping member 124 is provided with a clearance hole for exposing the wafer chip area.

[0106] In some embodiments, see Figure 1 The packaging auxiliary device 100 further includes a positioning mechanism 180 located at the loading station A. Positioning mechanism 180 is used to obtain position information of the wafer expansion ring 11 in the first direction. The first transverse moving member 131 in the first feeding mechanism 130 aligns the first clamping member 133 with the wafer expansion ring 11 in the first direction in response to the position information fed back by positioning mechanism 180. Optionally, positioning mechanism 180 may employ a positioning camera.

[0107] Specifically, in the illustrated embodiment, given the consistent dimensions of the expanding ring 11 and the fixture 12, the first loading mechanism 150 and the second loading mechanism 160 ensure that the expanding ring 11 and the fixture 12 are positioned consistently at loading station A and assembly station B. After the first clamping member 133 is aligned with the expanding ring 11 in the first direction by the positioning mechanism 180, the first transverse moving member 131 drives the first clamping member 133 to move a fixed distance in the first direction, thereby achieving alignment of the first clamping member 133 with the fixture 12 in the first direction. Therefore, a positioning mechanism is not required at assembly station B.

[0108] In summary, see Figure 1 and Figure 2The packaging auxiliary device 100 of the present embodiment includes a frame 110, a detection mechanism 120, a first feeding mechanism 130, a second feeding mechanism 140, a first loading mechanism 150, a second loading mechanism 160, an unloading mechanism 170, and a positioning mechanism 180. The packaging auxiliary device 100 operates as follows: the first loading mechanism 150 retrieves the expansion ring 11 from the first magazine and aligns the expansion ring 11 with the first clamping member 133 in the second direction. The second loading mechanism 160 retrieves the clamp 12 from the second magazine and aligns the clamp 12 with the first clamping member 133 in the second direction. In response to the position information fed back by the positioning mechanism 180, the first transverse moving member 131 aligns the first clamping member 133 with the wafer expansion ring 11 in the first direction. The first feeding mechanism 130 transfers the wafer expansion ring 11 from the loading station A to the assembly station B for assembly with the fixture 12. The assembled assembly 10 is then transferred from the assembly station B to the movable carrier 122 at the test position C1. The movable carrier 122 then moves the assembly 10 to the test position C2 for optical chip inspection using the inspection component 121. The inspected assembly 10 is then transferred from the test position C2 to the tested position C3. The second feeding mechanism 140 transfers the assembly 10 from the movable carrier 122 at the tested position C3 to the unloading station D. The unloading station D moves the assembly 10 along the second direction into the third magazine 20.

[0109] The above-mentioned packaging auxiliary device 100 can realize the functions of wafer expansion ring loading and chip optical detection. The various workstations are arranged compactly. The transfer of products between different workstations is realized through the first feeding mechanism 130 and the second feeding mechanism 140. The movement of products between different positions of the detection station C is realized through the movable carrier 122. While realizing the flow of products, interference between different mechanisms is avoided, which helps to carry out each process efficiently and orderly, thereby simplifying the operation process and improving operation efficiency.

[0110] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0111] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of this patent shall be determined by the appended claims.
