Description

Technical Field

[0001] This invention belongs to the field of visual inspection device technology, and particularly relates to a pallet-based double-sided visual inspection device for materials. Background Technology

[0002] In the manufacturing process of electronic materials, visual inspection equipment is needed to inspect the appearance of the materials, including front and back inspection. Currently, multiple materials are usually transferred to various processes of the visual inspection equipment by carrying them on a tray.

[0003] Existing visual inspection devices typically include a conveying mechanism, a front inspection mechanism, a back inspection mechanism, and a flipping mechanism. The conveying mechanism transports a pallet carrying multiple materials to be inspected to various workstations. The conveying path of the conveying mechanism is equipped with front inspection workstations and back inspection workstations. The front inspection mechanism and the back inspection mechanism are respectively set at the front inspection workstations and back inspection workstations. The conveying mechanism transports the materials on the pallet to the front inspection workstation for front visual inspection. Then, the flipping mechanism flips the materials after front inspection so that the back side of all materials on the pallet is facing up. The conveying mechanism then transports the materials on the flipped pallet to the back inspection workstation for back visual inspection.

[0004] However, existing flipping mechanisms typically flip materials one by one, resulting in low flipping efficiency and affecting the detection efficiency of the testing device. Summary of the Invention

[0020] Please see Figures 1 to 9 As shown, an embodiment of the present invention provides a pallet-based double-sided visual inspection device for materials, which includes a first conveying section 10, a first detection section 20, a second conveying section 30, a second detection section 40, and a flipping section 50. The first conveying section 10 and the second conveying section 30 are along a first horizontal direction ( Figure 1 The conveying sections (in the X direction) are arranged in parallel intervals. The first conveying section 10 has a first inspection station and a first flipping station along its conveying path. The first conveying section 10 is configured to receive the first pallet 60 and sequentially convey the received first pallet 60 to the first inspection station and the first flipping station. The first inspection section 20 is located at the first inspection station and is configured to inspect the front of all materials on the first pallet 60 at the first inspection station. The first pallet 60 is a full pallet. The second conveying section 30 has a second inspection station and a second flipping station along its conveying path. The flipping unit 50 is connected to the first flipping station and the second flipping station. The flipping unit 50 is configured to pick up the first pallet 60 after the front side inspection at the first flipping station, flip the material on the first pallet 60 as a whole, and place it on the second flipping station. The second conveying unit 30 is configured to receive the first pallet 60 after it has been flipped by the flipping unit 50 and convey the received first pallet 60 to the second inspection station. The second inspection unit 40 is set at the second inspection station and is configured to inspect the reverse side of all the material on the first pallet 60 at the second inspection station.

[0021] The pallet-based double-sided visual inspection device provided in this embodiment of the invention sets up a flipping part 50 between the first flipping station of the first conveying part 10 and the feeding station of the second conveying part 30. The flipping part 50 flips the entire pallet at the first flipping station and places it on the second flipping station, thereby realizing the automatic flipping of the entire pallet at one time and greatly improving the efficiency of material flipping.

[0022] In one embodiment, the first conveying unit 10 further includes a loading station, at which the first conveying unit 10 receives the first pallet 60 and conveys the received first pallet 60 to the first inspection station. The second conveying unit 30 further includes a unloading station, and the second conveying unit 30 is further configured to convey the first pallet 60 after reverse inspection at the second inspection station to the unloading station. Both the first conveying unit 10 and the second conveying unit 30 are along a second horizontal direction. Figure 1 Extending in the Y direction, with the first horizontal direction perpendicular to the second horizontal direction, the flipping part 50 includes a drive mechanism 51 and a clamping mechanism 52. The drive end of the drive mechanism 51 is connected to the clamping mechanism 52. The drive mechanism 51 is configured to drive the clamping mechanism 52 to rotate, thereby causing the clamping mechanism 52 to alternately move to a first flipping station, a waiting station, or a second flipping station. The first flipping station and the second flipping station are located on opposite sides of the waiting station, respectively. The clamping mechanism 52 is configured to clamp the second pallet 70 at the waiting station, clamp the stacked first pallet 60 and second pallet 70 at the first flipping station, and clamp the second pallet 70 at the second flipping station. The first and second surfaces of the first pallet 60 and the second pallet 70 are respectively provided with multiple material slots, each material slot being configured to accommodate one material. The drive mechanism 51 drives the clamping mechanism 52 to rotate so that the second pallet clamped by the clamping mechanism 52... The second pallet 70 is moved from the waiting station to the first flipping station and released, so that the second pallet 70 is stacked on top of the first pallet 60 at the first flipping station. The first surface of the first pallet 60 at the first flipping station is facing upward and one material is placed in each material slot of the first surface. After stacking, the material slots of the first pallet 60 and the second pallet 70 correspond one-to-one. The driving mechanism 51 drives the clamping mechanism 52 to rotate so that the first pallet 60 and the second pallet 70 held by the clamping mechanism 52 are moved from the first flipping station to the second flipping station, so that the material in all the material slots in the first pallet 60 is flipped and transferred to the corresponding material slots in the second pallet 70, so that the second pallet 70 is converted into the first pallet 60. The driving mechanism 51 drives the clamping mechanism 52 to rotate so that the second pallet 70 held by the clamping mechanism 52 is moved from the second flipping station to the waiting station, so that the first pallet 60 is converted into the second pallet 70.

[0023] Specifically, the second pallet, number 70, was empty.

[0024] Through the cooperation of the drive mechanism 51 and the clamping mechanism 52, a flipping part 50 is provided to drive the first pallet 60 and / or the second pallet 70 to switch smoothly and efficiently between different work stations; by using the first pallet 60 and the second pallet 70 with material troughs on both sides, the second pallet 70 can be automatically converted into the first pallet 60 at the waiting work station, further improving the continuity of material flipping and work efficiency.

[0025] In one embodiment, the clamping mechanism 52 includes a first drive assembly 520, a flipping frame 521, a first clamping member 522, and a second clamping member 523. The drive end of the drive mechanism 51 is connected to the flipping frame 521, and the drive mechanism 51 drives the flipping frame 521 to flip by a preset angle. The fixed end of the first drive assembly 520 is disposed on the flipping frame 521. The first clamping member 522 and the second clamping member 523 are spaced apart along a second horizontal direction and can be mounted on the flipping frame 521 close to or far from each other. The drive end of the first drive assembly 520 is connected to the first clamping member 522 and / or the second clamping member 523. The first drive assembly 520 is configured to drive the first clamping member 522 and the second clamping member 523 to move closer to or further away from each other to clamp or release the opposite two side walls of the first tray 60 and / or the second tray 70.

[0026] Specifically, both the first clamping member 522 and the second clamping member 523 include a connecting arm 5220 and a clamping arm 5221. The first end of the connecting arm 5220 is connected to the driving end of the first driving assembly 520, and the second end of the connecting arm 5220 is connected to the clamping arm 5221 by bolts. The clamping arm 5221 has at least one clearance groove. A slotted hole extending along the width direction of the clamping surface is provided in the clearance groove near the bottom of the connecting arm 5220. The connecting arm 5221 has at least one threaded hole corresponding to the slotted hole. The threaded section of the bolt passes through the slotted hole and is tightened in the corresponding threaded hole, and the pressing surface of the bolt presses against the bottom of the clearance groove. This not only realizes the detachable connection between the clamping arm 5221 and the connecting arm 5220, making it easy to replace the clamping arm 5221, but also enables the clamping arm 5221 to be installed in an adjustable manner along the length direction of the clamping surface, thereby facilitating adaptation to different material handling conditions and improving the applicability of the device.

[0027] Specifically, the drive end of the first drive component 520 is connected to the first clamping member 522 and the second clamping member 523.

[0028] By cooperating with the first drive assembly 520, the flipping frame 521, the first clamping member 522, and the second clamping member 523, a clamping mechanism 52 that provides stable, precise, and simple clamping is provided.

[0029] In one embodiment, the clamping mechanism 52 further includes two sets of positioning components 524, which are respectively disposed on the first clamping member 522 and the second clamping member 523. Each positioning component 524 includes a limiting member 5240 and at least one set of clamping components 5241. The limiting member 5240 protrudes from the clamping surface of the first clamping member 522 or the second clamping member 523. The clamping components 5241 are disposed on the first clamping member 522 or the second clamping member 523. The clamping components 5241 are spaced apart from the limiting member 5240. The clamping components 5241 are configured to clamp and fix the side of the corresponding pallet to the corresponding limiting member 5240 after the first clamping member 522 and the second clamping member 523 clamp the corresponding pallet and before the driving mechanism 51 drives the flipping frame 521 to flip.

[0030] Specifically, the limiting member 5240 is a boss extending along the length of the clamping surface. The boss is set on the first side of the clamping surface of the corresponding first clamping member 522 or second clamping member 523. The cylinder is installed on the second side of the clamping surface of the corresponding first clamping member 522 or second clamping member 523. The limiting surface of the boss is a plane, which ensures stable contact with the corresponding pallet and uniform force distribution. This not only further ensures the stability of the pallet when it is clamped, but also has a simple structure.

[0031] Specifically, there are two sets of clamping components 5241. The two sets of clamping components 5241 are spaced apart along the length of the clamping surface to achieve multi-point synchronous clamping on the side of the pallet. The clamping is more uniform and the force is more balanced, avoiding uneven force on the corresponding pallet due to single-point clamping, which may cause it to shift or even be damaged. This ensures accurate and reliable positioning throughout the flipping process.

[0032] Specifically, each set of clamping components 5241 includes a mounting plate, a first cylinder, and a clamping member. The mounting plate is fixedly mounted on the corresponding first clamping member 522 or second clamping member 523. The fixed end of the first cylinder is mounted on the mounting plate, and the driving end of the first cylinder extends toward the limiting member 5240. The clamping member is mounted on the driving end of the first cylinder, and the first cylinder drives the clamping member to move closer to or away from the limiting member 5240.

[0033] Specifically, the clamping component is a clamping rod, which is coaxial with and fixedly installed with the corresponding first cylinder.

[0034] By setting clamping components 5241 on the first clamping member 522 and the second clamping member 523 respectively, after clamping the pallet, the clamping components 5241 cooperate with the corresponding limiting member 5240 to clamp and fix the side of the corresponding pallet, thereby achieving dual fixation of the pallet sidewall clamping and side clamping, with good fixing effect and effectively preventing the corresponding pallet from shifting during the flipping process.

[0035] In one embodiment, the clamping mechanism 52 further includes an auxiliary clamping component 525, which is disposed between the first clamping member 522 and the second clamping member 523. The auxiliary clamping component 525 includes a transverse member 5250, a second driving component 5251, a third driving component 5252, a third clamping member 5253, and a fourth clamping member 5254. The third clamping member 5253 and the fourth clamping member 5254 are disposed on the transverse member 5250, either close to or far from each other. The fixed end of the third driving component 5252 is disposed on the transverse member 5250, and the driving end of the third driving component 5252 is connected to the first clamping member 5250. The third drive assembly 5252 is configured to drive the third clamping member 5253 and the fourth clamping member 5254 to move closer to or further away from each other to clamp or release the upper and lower surfaces of the first tray 60 and the second tray 70; the fixed end of the second drive assembly 5251 is mounted on the flipping frame 521, and the drive end of the second drive assembly 5251 is connected to the transverse member 5250. The second drive assembly 5251 is configured to drive the transverse member 5250 to move closer to or further away from the first tray 60 and the second tray 70 clamped by the first clamping member 522 and the second clamping member 523.

[0036] Specifically, the second drive assembly 5251 includes a second cylinder, the telescopic end of which faces the transverse member 5250.

[0037] Specifically, the drive end of the third drive component 5252 is connected to the third clamping member 5253 and the fourth clamping member 5254.

[0038] Specifically, both the first drive assembly 520 and the third drive assembly 5252 include a dual-piston rod cylinder, with the two piston rods on each dual-piston rod cylinder driving in opposite directions.

[0039] By providing an auxiliary clamping component 525 between the first clamping member 522 and the second clamping member 523, the upper surface of the first tray 60 and the lower surface of the second tray 70 after being clamped are clamped, thereby further fixing the first tray 60 and the second tray 70 and improving the stability during the flipping process.

[0040] In one embodiment, the drive mechanism 51 is further configured to drive the clamping mechanism 52 to rise and fall. The drive mechanism 51 includes a base 510, a fourth drive component 511, and a sixth drive component 512. The fixed end of the fourth drive component 511 is disposed on the base 510, and the flipping frame 521 is rotatably disposed on the base 510. The drive end of the fourth drive component 511 is connected to the flipping frame 521, and the fourth drive component 511 is configured to drive the flipping frame 521 to rotate by a preset angle. The drive end of the sixth drive component 512 is connected to the base 510, and the sixth drive component 512 is configured to drive the base 510 to rise and fall, so as to synchronously drive the clamped first tray 60 and / or second tray 70 to rise and fall through the clamping mechanism 52.

[0041] Specifically, the fourth drive assembly 511 is a rotary drive module that uses a motor and a coupling.

[0042] Specifically, the sixth drive component 512 adopts a conventional lifting drive module.

[0043] Through the cooperation of the base 510, the fourth drive assembly 511 and the sixth drive assembly 512, a drive mechanism 51 is provided that can drive the rotation and lifting of the clamping mechanism 52, which is convenient to adapt to the first and second flipping stations of different heights, thus improving the applicability of the device; the structure is simple and compact.

[0044] In one embodiment, both the first conveying unit 10 and the second conveying unit 30 include a carrying component 11, a fifth driving component 12, and a lifting component 13.
