Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor manufacturing machinery, in particular to a double-sided detection platform. Background Art

[0002] During the production process, it is often necessary to test various samples to ensure that the samples perform well when used. Among them, for thin sheet test pieces, since the test pieces themselves are thin but have a large area, their edge areas are often blocked by the components that fix the test pieces during testing. If it is a single-sided test platform, the components with higher heights can be set on the side that does not need to be tested to avoid shading. For double-sided test platforms, when both sides need to be tested, the components arranged on either side of the test station will block the fill light of the test piece at the test station, making it impossible for the image acquisition module to obtain complete or clear image information of the test piece, resulting in unreliable test results and affecting the quality of the entire finished product.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0046] The utility model provides a double-sided detection platform 100, which is suitable for detecting two surfaces of a detection piece at the same time, and is particularly suitable for detecting a thin sheet-shaped detection piece.

[0047] Specifically, see Figure 1 and Figure 2In this embodiment, the double-sided detection platform 100 includes a base 1, a conveying platform 2 and two groups of image acquisition modules (not shown in the drawings); the conveying platform 2 is arranged on the base 1, and is used to convey the detection member along the lateral direction of the base 1; the two groups of image acquisition modules are movably arranged on the base 1, and are respectively located on the upper and lower sides of the conveying platform 2, and each image acquisition module includes a fill light component, and the fill light component moves along the base 1 to form a fill light area. The thickness of the conveying platform 2 corresponding to the fill light area is less than the thickness of the conveying platform 2 at other positions.

[0048] In this embodiment, the base 1 is used to support the conveying platform 2 and the image acquisition module. The conveying platform 2 can convey and move the detection piece, making the detection of the detection piece more intelligent; the two groups of image acquisition modules can be used to respectively obtain image information of the upper and lower sides of the detection piece, so that the two surfaces of the detection piece can be detected at the same time, the detection efficiency is higher, and the detection structure is simpler; and, because the fill light is irradiated on the detection piece, especially when irradiating the edge area where the detection piece is connected to the conveying platform 2, if the height of the conveying platform 2 is too high, the light irradiated by the fill light will be blocked, resulting in a shadow on the detection piece, making the image acquired by the image acquisition module unclear, therefore, the thickness of the conveying platform 2 corresponding to the fill light area is smaller than the thickness of the rest of the conveying platform 2, so that the fill light can better irradiate various positions of the detection piece, so that the image acquired by the image acquisition module can be clearer, all parts of the detection piece can be detected, and the detection result is more reliable, thereby ensuring better quality of the finished product.

[0049] It should be noted that when the double-sided inspection platform 100 is working normally, the above-mentioned transverse direction refers to a direction along the horizontal plane, and the longitudinal direction in the present invention refers to a direction perpendicular to the transverse direction on the horizontal plane. Figure 1 and Figure 2 As shown, when the transverse direction is the left-right direction of the base 1, the longitudinal direction may refer to the front-back direction along the base 1. If there is no special description about the directions in the present utility model, all of them can be referred to as such.

[0050] The base 1 is a carrier suitable for mounting other components, and the base 1 can also be connected to other structures, so that the double-sided detection platform 100 can be fixed on other structures. The setting form of the base 1 is not specifically limited, and can be set according to actual installation requirements. Preferably, the base 1 can be set as a bottom plate, and a mounting hole can be set on the bottom plate to facilitate the connection and fixation of the double-sided detection platform 100 with other structures.

[0051] Two groups of image acquisition modules are used to detect the two detection surfaces of the detection part. Specifically, each image acquisition module also includes a camera structure, and a fill light is arranged at the front end of the camera structure, specifically, it can be located at the front end of the lens of the camera structure to better illuminate the detection part, so that the acquired image information is clearer. Among them, the camera structure is movably arranged on the base 1, and the movement of the camera structure can better capture various positions of the detection part, and the focusing effect is better. When the camera structure moves, the fill light moves with the camera structure to better illuminate the shooting area. Moreover, the two camera structures located on the upper and lower sides of the conveying platform 2 can simultaneously obtain the image information of the upper and lower detection surfaces of the detection part, and the detection efficiency is higher.

[0052] When the detection part is being transported on the conveying platform 2, only a few places on the edge of the detection part are connected to the conveying platform 2. It is understandable that when the image acquisition module is shooting, when the camera structure needs to capture the image of the edge area of ​​the detection part, if the height of the structure connected to the detection part is high, the light irradiated by the fill light will cause the structure connected to the detection part to form a shadow at the edge of the detection part, thereby making the image at the edge of the detection part unclear, thereby affecting the detection effect. Therefore, the thickness of the conveying platform 2 corresponding to the fill light area is smaller than the thickness of the rest of the conveying platform 2, so that the height of each component of the double-sided detection platform 100 located in the fill light area should be as small as possible, to ensure that the fill light can evenly illuminate each position of the detection part, so that each image information of the detection part obtained is clearer, to ensure better and more reliable detection effect.

[0053] The fill light area includes the area where the detection part is located, and the edge area of ​​the detection part covered by the fill light when the fill light is irradiated to the edge of the detection part. The fill light is generally arranged in a ring shape. When the fill light irradiates the edge area of ​​the detection part, the center of the fill light corresponds to the edge of the detection part. The circular area with the edge of the detection part as the center and the radius of the fill light itself as the radius should all belong to the fill light area. Therefore, in the corresponding fill light area, the height of each component of the double-sided detection platform 100 is relatively low, and preferably, the components with higher height are moved outside the double-sided detection platform 100 or the higher components are laid down to meet the fill light illumination requirements of the fill light, so that the detection part can be illuminated everywhere without forming a shadow.

[0054] Specifically, combined Figure 1 and Figure 2As shown, the conveying platform 2 includes a conveying frame 21, and a first conveying section 22, a detection section 23 and a second conveying section 24 arranged on the conveying frame 21 in sequence. The conveying frame 21 is arranged to extend in the lateral direction of the base 1, and is used for the first conveying section 22, the detection section 23 and the second conveying section 24 to be installed and fixed thereon. The first conveying section 22 can convey the detection piece in the lateral direction of the base 1, so as to convey it in the direction of the detection section 23. The detection section 23 is used to fix the detection piece, so that the image acquisition module can detect the detection piece. The second conveying section 24 is used to move the detection piece in the direction away from the detection section 23, so that the detection piece can automatically enter the next process. The double-sided detection platform 100 also includes a material-dispensing mechanism 3 movably arranged on the conveying platform 2, and the material-dispensing mechanism 3 is used to push the detection piece from the first conveying section 22 to the detection section 23, and to push the detection piece from the detection section 23 to the second conveying section 24, so that the detection piece is better placed in the detection section 23, and after the detection is completed, the detection piece can be moved out from the detection section 23.

[0055] Preferably, the thickness of the detection section 23 is smaller than the thickness of the first transmission section 22 and the second transmission section 24, so that the image acquisition module can better detect and avoid occlusion. The thickness refers to the dimension along the up and down direction of the base 1.

[0056] Moreover, if Figure 1 As shown in the figure, the first conveying section 22 includes a plurality of first conveying wheels rotatably arranged on the conveying frame 21, a first conveying belt 221 sleeved on the plurality of first conveying wheels, and a first conveying driving structure 222 connected to at least one of the first conveying wheels, and at least one of the first conveying wheels is driven to rotate by the first conveying driving structure 222, so as to drive the first conveying belt 221 to move, so that the detection member placed on the first conveying belt 221 can move in the direction of the detection section 23 along the lateral direction of the base 1; the second conveying section 24 includes a plurality of second conveying wheels rotatably arranged on the conveying frame 21, a second conveying belt 241 sleeved on the plurality of second conveying wheels, and a second conveying driving structure 242 connected to at least one of the second conveying wheels, and at least one of the second conveying wheels is driven to rotate by the second conveying driving structure 242, so as to drive the second conveying belt 241 to move, so that the detection member placed on the second conveying belt 241 can move in the direction of the lateral direction of the base 1 away from the detection section 23.

[0057] Since the diameters of the first transmission wheel and the second transmission wheel cannot be too small, in order to make the thickness of the detection section 23 smaller, preferably, the detection section 23 includes a clamping member 231 and a clamping driving structure 233 connected to the clamping member 231, and the clamping driving structure 233 is used to drive the clamping member 231 to move, so as to clamp or release the detection member, so as to fix the detection member by clamping for detection.

[0058] Furthermore, combined with Figures 5 to 8 As shown, the clamping drive structure 233 includes a clamping driver 2331 and a clamping transmission block 2332, the clamping driver 2331 is arranged on the conveying frame 21; the clamping transmission block 2332 is connected to the clamping driver 2331 and has a lateral movable stroke along the base 1; the clamping member 231 includes a first clamping plate 2311, and a rotating shaft 232 rotatably connecting the first clamping plate 2311 and the conveying frame 21; wherein a contact matching structure is formed between the transmission block and the first clamping plate 2311, when the clamping driver 2331 drives the clamping transmission block 2332 to move laterally along the base 1, the first clamping plate 2311 can be driven to rotate around the rotating shaft 232 under the action of the contact matching structure to clamp or release the detection member. By converting the linear motion of the clamping transmission block 2332 driven by the clamping driver 2331 into the rotation of the first clamping plate 2311, the first clamping plate 2311 is not clamped and released by moving up and down, and the movable stroke is smaller, thereby occupying less space, making the overall thickness of the detection section 23 thinner, so that it is not easy to block the light of the fill light, thereby ensuring a better lighting effect.

[0059] Since the volume of the clamping driver 2331 is relatively large, the clamping driver 2331 should be set at a position away from the detection section 23, so as to fix the clamping driver 2331 to the conveying frame 21 at a position corresponding to the second conveying section 24, so as to reduce the overall thickness of the detection section 23. Moreover, since the clamping driver 2331 is preferably configured as a driving cylinder, the driving cylinder is generally configured in an elongated shape to have a long side and a short side, preferably, the long side of the clamping driver 2331 is configured along the lateral direction of the base 1, so as to reduce the thickness of the conveying platform 2 in the up-and-down direction along the base 1.

[0060] Furthermore, if Figure 6 As shown in , the contact matching structure includes a transmission roller 2334 connected to the clamping transmission block 2332, and a first wedge-shaped surface 2312 provided on one side of the first clamping plate 2311. The clamping end of the first clamping plate 2311 and the first wedge-shaped surface 2312 are respectively located on both sides of the rotating shaft 232, and the transmission roller 2334 abuts against the bottom of the first wedge-shaped surface 2312. When the clamping driver 2331 drives the transmission roller 2334 to move along the wedging direction, the transmission roller 2334 can abut against the first wedge-shaped surface 2312, so that the clamping end of the first clamping plate 2311 moves toward the clamping direction. The transmission roller 2334 contacts the first wedge-shaped surface 2312 to abut against the first wedge-shaped surface 2312, so that the first clamping plate 2311 can rotate around the rotating shaft 232, thereby clamping or releasing the detection member.

[0061] Moreover, if Figure 8As shown in , the clamping driving structure 233 also includes an elastic reset member 2333, which is arranged on the conveying frame 21 and abuts between the conveying frame 21 and the first clamping plate 2311; when the clamping driver 2331 drives the transmission roller 2334 to move in the wedging direction, the transmission roller 2334 can gradually move away from the first wedge surface 2312, and the clamping end of the first clamping plate 2311 can be driven to move in the direction of loosening under the action of the elastic reset member 2333. The elastic reset member 2333 can be set as a telescopic spring, which is arranged in the up-down direction, and the two ends of the telescopic spring are respectively abutted on the conveying frame 21 and the first clamping plate 2311. When the clamping driver 2331 drives the clamping transmission block 2332 to move, so that the transmission roller 2334 moves in the wedging direction, the transmission roller 2334 can push against the first wedge surface 2312 and move upward, so that the clamping end of the first clamping plate 2311 moves downward to clamp the detection piece. At this time, the telescopic spring is in a compressed state. When the clamping driver 2331 drives the clamping transmission block 2332 to move, so that the transmission roller 2334 moves in the wedging direction, the abutting force of the transmission roller 2334 on the first wedge surface 2312 gradually decreases, and under the action of the elastic restoring force of the telescopic spring, the clamping end of the first clamping plate 2311 moves upward, thereby making the first clamping plate 2311 in a state of loosening the detection piece, so that the detection piece can be pushed into the detection section 23 or pushed out of the detection section 23 through the material diverting mechanism 3.

[0062] Preferably, combined Figure 3 and Figure 4 As shown, the material shifting mechanism 3 includes a material shifting rod 31 and a material shifting driving structure 32. The material shifting rod 31 is movably arranged on the base 1 and is arranged corresponding to the detection section 23. The material shifting rod 31 has an active stroke along the up-down direction and the lateral direction of the base 1; the material shifting driving structure 32 is arranged on the base 1 and is connected to the material shifting rod 31, and is used to drive the material shifting rod 31 to move along the up-down direction and the lateral direction of the base 1. When the detection piece is transferred to the detection section 23 via the first conveying section 22 and has not been completely moved into place, the material-moving rod 31 can be driven to move by the material-moving driving structure 32, so that the material-moving rod 31 can be moved to the first end of the detection piece close to the first conveying section 22, so as to move the material-moving rod 31 downward to contact the first end of the detection piece, and then the material-moving driving structure 32 drives the material-moving rod 31 to move in the direction of the second conveying section 24 along the lateral direction of the base 1 to push the detection piece to move until it moves into place; when the detection is completed, the detection piece can be driven to move again, and under the push of the material-moving rod 31, the detection piece can enter the second conveying section 24, and then under the conveying action of the second conveying section 24, the detection is transferred to the next process.

[0063] Among them, a first sensor and a second sensor can be respectively arranged at both ends of the detection section 23 in the lateral direction. The first sensor is used to detect that the detection member moves from the first conveying section 22 to the detection section 23, so as to control the material-pickup driving structure 32 to work, so as to drive the material-pickup rod 31 to move and push the material; the second sensor is used to detect the position of the second end of the detection member, and then determine that the detection member moves to the detection section 23. The detection operation of the double-sided detection platform 100 is more intelligent, so that the detection efficiency is higher. Moreover, the first sensor and the second sensor are preferably optical fiber sensors, which are smaller in size and occupy less space, so that the overall thickness of the detection section 23 is smaller.

[0064] As for the conveying frame 21, the conveying frame 21 is a conveying steel frame structure extending along the lateral direction of the base 1. The conveying frame 21 can be integrally arranged at the corresponding first conveying section 22, the detection section 23 and the second conveying section 24, or the conveying frame 21 can be arranged in sections at the corresponding first conveying section 22, the detection section 23 and the second conveying section 24, so as to facilitate disassembly and assembly. The conveying frame 21 includes two conveying guide rails arranged in parallel and spaced apart along the longitudinal direction of the base 1, wherein at least one of the conveying guide rails is movably arranged so that the two conveying guide rails can be close to or away from each other. When the size of the inspection piece is different, the distance between the two conveying guide rails can be adjusted to support and convey the inspection pieces of different sizes, so that the double-sided inspection platform 100 can correspond to the inspection requirements of different inspection pieces and has a wider range of applications.

[0065] Among them, combined Figure 3 and Figure 4 As shown, a first inclined surface 211 is provided at the bottom of the conveyor frame 21. The first inclined surface 211 is located at the detection section 23 to reduce the thickness of the detection section 23, so that when the image acquisition module acquires image information at the edge where the detection piece is connected to the detection section 23, the light of the fill light can be better irradiated to the edge of the detection piece through the first inclined surface 211, thereby ensuring a better detection effect.

[0066] Moreover, two sets of conveying platforms 2 are provided, and the conveying frames 21 of the two sets of conveying platforms 2 are arranged in parallel and at intervals. Two inspection pieces can be inspected at the same time through a double-sided inspection platform 100, and the inspection efficiency is higher.

[0067] The two sets of conveying platforms 2 include four parallel and spaced conveying rails. Figure 1 and Figure 2 As shown, the two conveying guide rails in the middle are movably arranged, which can better ensure the overall width of the conveying platform 2 and can also be adapted to the inspection requirements of different inspection parts.

[0068] Specifically, the double-sided inspection platform 100 includes two sets of guide rail drive structures 4, which are connected to two movable conveying guide rails one by one, so that the movement of each conveying guide rail is more flexible. Each guide rail drive structure 4 includes a guide rail driver 41, a screw rod 32 connected to the guide rail driver 41, and a nut connected to the screw rod 32. The screw rod 32 is extended along the longitudinal direction of the base 1, and the nut is arranged on the movable conveying guide rail. The screw rod 32 is driven to rotate by the guide rail driver 41, so that the nut can move along the screw rod 32, thereby driving the conveying guide rail to move.

[0069] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the specification and drawings of the present invention, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present invention.
