[0002] In the manufacturing process of electronic materials, visual inspection equipment is required to inspect the appearance of the materials, including front and back inspection. Currently, multiple materials are usually transported to various processes on a pallet. Existing visual inspection equipment includes a conveying mechanism, a front inspection mechanism, and a back inspection mechanism. During inspection, the conveying mechanism first transports the pallet and the multiple materials it carries to the front inspection mechanism, which inspects the upper surface of the multiple materials on the pallet. Then, the multiple materials on the pallet are manually flipped over so that the lower surface of the multiple materials on the pallet faces upward. Finally, the conveying mechanism transports the pallet with the flipped materials to the back inspection mechanism, which inspects the lower surface of the multiple materials on the pallet.

[0019] Please see Figures 1 to 6As shown in the embodiment of this application, a pallet-based material overall flipping device includes a drive mechanism 10 and a clamping mechanism 20. The drive end of the drive mechanism 10 is connected to the clamping mechanism 20. The drive mechanism 10 is configured to drive the clamping mechanism 20 to rotate, thereby causing the clamping mechanism 20 to alternately move to a loading station, a waiting station, or a unloading station. The loading station and the unloading station are located on opposite sides of the waiting station. The clamping mechanism 20 is configured to clamp a first pallet 30 at the waiting station, clamp stacked first pallets 30 and second pallets 40 at the loading station, and clamp a second pallet 40 at the unloading station. Multiple material slots are correspondingly provided on the first and second surfaces of the first pallet 30 and the second pallet 40, and each material slot is configured to accommodate one material. The drive mechanism 10 drives the clamping mechanism 20 and... The first pallet 30 held by the clamping mechanism is moved from the waiting station to the loading station. The clamping mechanism 20 releases the first pallet 30 to stack it on top of the second pallet 40 at the loading station. The first surface of the second pallet 40 at the loading station faces upward and one material is placed in each groove of the first surface. After stacking, the grooves of the first pallet 30 and the second pallet 40 correspond one-to-one. The driving mechanism 10 drives the clamping mechanism 20 and the first pallet 30 and the second pallet 40 held by the clamping mechanism to move from the loading station to the unloading station to flip all the materials in the grooves of the second pallet 40 and transfer them to the corresponding grooves in the first pallet 30. The driving mechanism 10 drives the clamping mechanism 20 and the second pallet 40 held by the clamping mechanism to move from the unloading station to the waiting station so that the second pallet 40 is converted into the first pallet 30.

[0020] Specifically, the loading and unloading stations are set up at intervals along the horizontal direction.

[0021] The pallet-based material flipping device provided in this embodiment of the invention uses a clamping mechanism 20 to clamp stacked first pallets 30 and second pallets 40. The drive mechanism 10 rotates the clamping mechanism 20 from the loading station to the unloading station, enabling automatic flipping of the entire pallet at once, significantly improving work efficiency. Automated operation ensures the continuity and stability of material flipping. The use of a first pallet 30 and a second pallet 40 with material troughs on both sides allows the second pallet 40 to automatically transform into the first pallet 30 at the waiting station, further improving the continuity and efficiency of material flipping.

[0022] In one embodiment, the clamping mechanism 20 includes a first drive assembly 21, a flipping frame 22, a first clamping member 23, and a second clamping member 24. The drive end of the drive mechanism 10 is connected to the flipping frame 22, and the drive mechanism 10 drives the flipping frame 22 to flip at a preset angle. The fixed end of the first drive assembly 21 is disposed on the flipping frame 22. The first clamping member 23 and the second clamping member 24 are mounted on the flipping frame 22, which can be close to or far away from each other. The drive end of the first drive assembly 21 is connected to the first clamping member 23 and / or the second clamping member 24. The first drive assembly 21 is configured to drive the first clamping member 23 and the second clamping member 24 to move closer to or further away from each other, so as to clamp or release the opposite two side walls of the first tray 30 and / or the second tray 40.

[0023] Specifically, the flipping frame 22 is equipped with two sets of sliding guide pairs 27. The two sets of sliding guide pairs 27 correspond to the first clamping member 23 and the second clamping member 24 respectively. Each set of sliding guide pairs 27 includes a slide rail 270 and a slider 271. The slide rail 270 extends along the length of the clamping surface and is disposed on the corresponding clamping member. The slider 271 is fixedly connected to the flipping frame 22 and slidably sleeved on the slide rail 270.

[0024] Specifically, both the first clamping member 23 and the second clamping member 24 include a connecting arm 230 and a clamping arm 231. The first end of the connecting arm 230 is connected to the driving end of the first driving assembly 21, and the second end of the connecting arm 230 is connected to the clamping arm 231 by bolts. The clamping arm 231 has at least one clearance groove 2310. The clearance groove 2310 has a waist-shaped hole extending along the width direction of the clamping surface near the bottom of the connecting arm 230. The connecting arm 230 has at least one threaded hole corresponding to the waist-shaped hole. The threaded section of the bolt passes through the waist-shaped hole and is tightened in the corresponding threaded hole, and the pressing surface of the bolt presses against the bottom of the clearance groove 2310. This not only realizes the detachable connection between the clamping arm 231 and the connecting arm 230, making it easy to replace the clamping arm 231, but also realizes the adjustable installation of the clamping arm 231 along the length direction of the clamping surface, thereby making it easier to adapt to different material feeding station conditions and improving the applicability of the device.

[0025] Specifically, the drive end of the first drive component 21 is connected to the first clamping member 23 and the second clamping member 24.

[0026] By cooperating with the first drive assembly 21, the flipping frame 22, the first clamping member 23, and the second clamping member 24, a clamping mechanism that provides stable, precise, and simple clamping is provided.

[0027] In one embodiment, the clamping mechanism 20 further includes two sets of positioning components 25, which are respectively disposed on the first clamping member 23 and the second clamping member 24. Each positioning component 25 includes a limiting member 250 and at least one set of clamping components 251. The limiting member 250 protrudes from the clamping surface of the first clamping member 23 or the second clamping member 24, and the clamping components 251 are disposed on the first clamping member 23 or the second clamping member 24. The clamping components 251 and the limiting member 250 are spaced apart. The clamping components 251 are configured to clamp and fix the side of the corresponding tray to the limiting member 250 after the first clamping member 23 and the second clamping member 24 clamp the corresponding tray and before the drive mechanism 10 drives the flipping frame 22 to flip.

[0028] Specifically, the limiting member 250 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 23 or second clamping member 24. The cylinder is installed on the second side of the clamping surface of the corresponding first clamping member 23 or second clamping member 24. 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.

[0029] Specifically, there are two sets of clamping components 251. The two sets of clamping components 251 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.

[0030] By setting clamping components 251 on the first clamping member 23 and the second clamping member 24 respectively, after clamping the pallet, the clamping components 251 cooperate with the corresponding limiting member 250 to clamp and fix the side of the corresponding pallet, thereby achieving dual fixation of the pallet sidewall clamping and side clamping, which has a good fixing effect and effectively prevents the corresponding pallet from shifting during the flipping process.

[0031] In one embodiment, each set of clamping components 251 includes a mounting plate 2510, a cylinder 2511, and a clamping member (not shown in the figure). The mounting plate 2510 is fixedly mounted on the corresponding first clamping member 23 or second clamping member 24. The fixed end of the cylinder 2511 is mounted on the mounting plate 2510, and the driving end of the cylinder 2511 extends toward the limiting member 250. The clamping member is mounted on the driving end of the cylinder 2511, and the cylinder 2511 drives the clamping member to move closer to or away from the limiting member 250.

[0032] Specifically, the clamping component is a clamping rod, which is coaxial with and fixedly installed with the corresponding cylinder 2511.

[0033] The cylinder 2511 is fixed to the corresponding clamping component by the mounting plate 2510, and the cylinder 2511 drives the clamping component to move closer to or away from the limiting component 250, so as to realize the automatic clamping and loosening of the corresponding pallet side. While responding quickly, it ensures stable and continuous pressure on the pallet, further ensuring the stability of the pallet fixation.

[0034] In one embodiment, the clamping mechanism 20 further includes an auxiliary clamping component 26, which is disposed between the first clamping member 23 and the second clamping member 24. The auxiliary clamping component 26 includes a transverse sliding member 260, a second driving component 261, a third driving component 262, a third clamping member 263, and a fourth clamping member 264. The third clamping member 263 and the fourth clamping member 264 are disposed on the transverse sliding member 260, either close to or far from each other. The fixed end of the third driving component 262 is disposed on the transverse sliding member 260, and the driving end of the third driving component 262 is connected to the third clamping member 264. The third drive assembly 262 is configured to drive the third clamping member 263 and the fourth clamping member 264 to move closer to or further away from each other to clamp or release the upper and lower surfaces of the first tray 30 and the second tray 40; the fixed end of the second drive assembly 261 is mounted on the flipping frame 22, and the drive end of the second drive assembly 261 is connected to the transverse member 260. The second drive assembly 261 is configured to drive the transverse member 260 to move closer to or further away from the first tray 30 and the second tray 40 clamped by the first clamping member 23 and the second clamping member 24.

[0035] Specifically, the second drive assembly 261 includes a conventional cylinder with its extension and retraction end facing the transverse member 260.

[0036] Specifically, the drive end of the third drive component 262 is connected to the third clamping member 263 and the fourth clamping member 264.

[0037] Specifically, both the first drive assembly 21 and the third drive assembly 262 include a dual-piston rod cylinder, with the two piston rods on each dual-piston rod cylinder driving in opposite directions.

[0038] By providing an auxiliary clamping assembly 26 between the first clamping member 23 and the second clamping member 24, the upper surface of the first tray 30 and the lower surface of the second tray 40 after being clamped are further fixed, thereby improving the stability during the flipping process.

[0039] In one embodiment, the drive mechanism 10 is further configured to drive the clamping mechanism 20 to rise and fall. The drive mechanism 10 includes a base 11, a fourth drive component 12, and a fifth drive component 13. The fixed end of the fourth drive component 12 is disposed on the base 11, and the flipping frame 22 is rotatably disposed on the base 11. The drive end of the fourth drive component 12 is connected to the flipping frame 22, and the fourth drive component 12 is configured to drive the flipping frame 22 to rotate by a preset angle. The drive end of the fifth drive component 13 is connected to the base 11, and the fifth drive component 13 is configured to drive the base 11 to rise and fall, so as to synchronously drive the clamped first tray 30 and / or second tray 40 to rise and fall through the clamping mechanism 20.

[0040] Specifically, the fourth drive assembly 12 is a rotary drive module that uses a motor and a coupling.

[0041] Specifically, the fifth drive component 13 adopts a conventional lifting drive module.

[0042] Through the cooperation of the base 11, the fourth drive assembly 12 and the fifth drive assembly 13, a drive mechanism 10 is provided that can drive the clamping mechanism 20 to rotate and lift, which is convenient to adapt to loading and unloading stations of different heights and improves the applicability of the device; the structure is simple and compact.

[0043] In one embodiment, the pallet-based material overall flipping device further includes a first conveying mechanism 50 and a second conveying mechanism 60. The loading station is located at the discharge end of the first conveying mechanism 50, and the first conveying mechanism 50 is configured to receive a full second pallet 40 and convey the second pallet 40 to the loading station. The unloading station is located at the feed end of the second conveying mechanism 60, and the second conveying mechanism 60 is configured to receive a full first pallet 30 and convey the first pallet 30 to the next process.

[0044] Specifically, both the first conveying mechanism 50 and the second conveying mechanism 60 include a sixth drive assembly 53. The drive end of the sixth drive assembly 53 is connected to the corresponding lifting mechanism, and the sixth drive assembly 53 is configured to drive the corresponding lifting mechanism along the second horizontal direction. Figure 1 (In the direction of Y) it moves back and forth.

[0045] The first conveyor mechanism 50 and the second conveyor mechanism 60 are respectively connected to the loading station and the unloading station to realize automatic loading of full pallets and automatic unloading of pallets after flipping, eliminating the need for manual loading and unloading and improving the overall inspection efficiency.

[0046] In one embodiment, a first lifting mechanism 70 and a first lifting member are provided at the loading station. The first lifting member is located directly below the loading station. The discharge end of the first conveying mechanism 50 is provided with a lifting channel that avoids the first lifting member in a vertical direction. The drive end of the first lifting mechanism 70 is connected to the first lifting member. The first lifting mechanism 70 is configured to drive the first lifting member to rise and fall, so that the first lifting member passes through the lifting channel and drives the second tray 40 to move closer to the first tray 30.

[0047] Specifically, the unloading station is equipped with a second lifting mechanism that has the same structure as the first lifting mechanism 70 and a second lifting component 71 that has the same structure as the first lifting component.

[0048] Specifically, both the first conveying mechanism 50 and the second conveying mechanism 60 include a first bearing member 51 and a second bearing member 52, the first bearing member 51 and the second bearing member 52 being along a first horizontal direction ( Figure 1 The first and second load-bearing members 51 and 52 are arranged in parallel and extend along the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction. A lifting channel is formed between the first load-bearing member 51 and the second load-bearing member 52. A first limiting step is provided on the inner side of the first load-bearing member 51 and a second limiting step is provided on the inner side of the second load-bearing member 52. The first limiting step is configured to support and position the first end of the corresponding pallet in the first horizontal direction, and the second limiting step is configured to support and position the second end of the corresponding pallet in the first horizontal direction.

[0049] The first lifting mechanism 70, in cooperation with the first lifting component, lifts the second pallet 40 upwards and brings it close to the first pallet 30, thereby achieving automatic bonding of the double-layer pallets, which is stable and precise.

[0050] In one embodiment, a plurality of support members 80 are arranged directly above the loading station. The plurality of support members 80 are fixedly installed at intervals at the discharge end of the first conveying mechanism 50. Each support member 80 includes a fixing block 81 and a support plate 82. The fixing block 81 is fixedly installed on the first conveying mechanism, and the support plate 82 is rotatably installed on the fixing block 81. The first side of the support plate 82 is the support surface. When the support plate 82 is in a horizontal state, the support surface faces upward and is horizontally arranged. The support surfaces of the plurality of support plates 82 jointly support the first pallet 30. The support plate 82 in the horizontal state interferes with the second pallet 40 in the vertical direction. When the second pallet 40 rises, it abuts against the second side of the support plate 82. Then, during the rising process of the second pallet 40, the support plate 82 is rotated to a vertical state. The support plate 82 in the vertical state does not interfere with the second pallet 40 in the vertical direction, and then the first pallet 30 and the second pallet 40 are attached to the first lifting member.

[0051] Specifically, several support members 80 are arranged one-to-one on the first bearing member 51 and the second bearing member 52 along the first horizontal direction.

[0052] The rotatable support plate 82 automatically avoids the first tray 30 when it is closed and resets to support it after the tray is closed, realizing the automatic switching between the closed and supported states of the first tray 30. The structure is simple, the operation is reliable, and it provides stable support for the first tray 30 without affecting the fit.

S2: Drive mechanism 10 drives clamping mechanism 20 to clamp the stacked first tray 30 and second tray 40; S3: The drive mechanism 10 drives the clamping mechanism 20 and the clamped first tray 30 and second tray 40 to rotate 180°, so that the first tray 30 and second tray 40 are moved from the loading station to the unloading station and the second tray 40 is located above the first tray 30. During the rotation process, the material in the second tray 40 is moved into the corresponding material trough of the first tray 30. S4: The clamping mechanism 20 releases the first pallet 30 of the unloading station and clamps the empty second pallet 40 of the unloading station.
