[0055] The core of the present invention is to disclose a material detection device to connect with the existing production line to complete the automatic detection of materials.

[0056] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0057] Combination Figure 1 and Figure 2 The material detection equipment disclosed in the present invention includes a detection module, a material loading module, a loading robot arm, an NG material transmission line, an OK material unloading module and an unloading robot arm 1400. The detection module includes a carrier for carrying material 6000 and a visual detection submodule for detecting material 6000; the material loading module is used to convey material 6000; the loading robot arm is used to transfer material 6000 from the material loading module to the carrier; the NG material transmission line is used to convey unqualified materials; the OK material unloading module is used to convey qualified materials; the unloading robot arm 1400 is used to transfer qualified materials detected by the visual detection submodule from the carrier to the OK material unloading module, and transfer unqualified materials to the NG material transmission line.

[0058] The material loading module is connected to the incoming material conveyor line. After the material 6000 is loaded by the material loading module, the loading robot arm transfers the material 6000 from the material loading module to the carrier. After the visual inspection submodule captures the image of the material 6000 on the carrier and inspects the material 6000 based on the image, the unloading robot arm 1400 transfers the qualified materials after inspection from the carrier to the OK material unloading module for plate unloading according to the inspection results, and the unqualified materials are transferred to the NG material transmission line, completing the inspection process of material 6000.

[0059] Compared with the prior art, the material detection equipment disclosed in the present invention realizes automatic loading and detection of material 6000, automatic plating and collecting of qualified products, and automatic unloading of unqualified products. It has a high degree of automation, can be connected to the existing production line, completes automatic detection of materials, and improves production efficiency.

[0060] The NG material transmission line can be a conveyor belt, and the unqualified materials are directly transported to the waste material 6000 for processing. The qualified materials need to be accurately placed in the tray 5000 and transported to the downstream material 6000. Therefore, the unloading robot arm 1400 can be one or two. When there is one, the robot arm unloads qualified materials and unqualified materials at the same time. When there are two, the two robot arms unload qualified materials and unqualified materials respectively.

[0061] In order to be able to automatically switch between empty and full trays, combined Figure 2 The OK material unloading module disclosed in the embodiment of the present invention includes a first pallet conveying assembly 1100, a second pallet conveying assembly 1200 and a transmission mechanism 1300, wherein the first pallet conveying assembly 1100 is used to convey an empty pallet 5000 to a transmission station, the transmission mechanism 1300 is used to transfer the pallet 5000 from the transmission station to the loading station, and the unloading robot arm 1400 is used to convey qualified materials to the pallet 5000 at the loading station. After the material 6000 fills the pallet 5000, the second transmission mechanism 1300 is used to transfer the pallet 5000 from the loading station to the downstream equipment, thereby completing the unloading process of the material 6000.

[0062] Specifically, combined Figure 3 and Figure 4 The first pallet conveying assembly 1100 includes a first carrier 1110, a first lifting member 1120 and a first transmission member 1130. The first carrier 1110 is used to carry empty pallets 5000. The first transmission member 1130 is used to transmit the stacked empty pallets 5000 to the loading station. The first lifting member 1120 is used to drive the first carrier 1110 to lift the stacked empty pallets 5000 from the loading station to the transmission station in sequence, and the pallets are transported away by the transmission mechanism 1300. After a group of empty pallets 5000 are transmitted, the first lifting member 1120 drives the first carrier 1110 to descend to the loading station. After the first transmission member 1130 transmits a group of empty pallets 5000 to the loading station again, the first carrier 1110 lifts the pallets 5000 from the loading station to the transmission station in sequence again.

[0063] Combination Figure 5 and Figure 6The second pallet conveying assembly 1200 includes a second carrier 1210, a second lifting member 1220 and a second transmission member 1230. The second carrier 1210 is used to carry the pallet 5000. The second lifting member 1220 is used to drive the second carrier 1210 to descend in sequence so that the pallets 5000 at the loading station can be stacked one by one on the second carrier 1210, and the pallets 5000 are transmitted to the unloading station on the second transmission member 1230. After the conveying mechanism 1300 moves the pallet 5000 to the loading station, the pallet 5000 is carried by the second carrier 1210. As the second carrier 1210 descends in sequence, each pallet 5000 is stacked on the second carrier 1210 in sequence. After the stacking number of pallets 5000 reaches a preset number, the first carrier 1110 drives the pallet 5000 to descend to the unloading station and completes the handover of the pallet 5000 with the second conveying member 1230. After the second conveying member 1230 moves the pallet 5000 away from the unloading station, the second carrier 1210 is reset and continues to receive subsequent pallets 5000.

[0064] Herein, a group of trays 5000 refers to a plurality of trays 5000 stacked in sequence in a vertical direction.

[0065] The present invention can realize automatic loading of an empty pallet 5000 and automatic unloading of a fully loaded pallet 5000, thereby ensuring a continuous supply of pallets 5000, promoting the degree of automation in the unloading process of materials 6000, improving production efficiency, and reducing production costs.

[0066] Specifically, in order to ensure the stable flow of the pallet 5000 between the loading station, the transfer station and the loading station, the Figure 2 and Figure 7 The first pallet conveying assembly 1100 includes a pre-positioning assembly 1150, and the pre-positioning assembly 1150 includes two initial positioning plates movably arranged on the first transmission member 1130 along an adjustment direction, and the adjustment direction is perpendicular to the conveying direction of the first transmission member 1130, and along the conveying direction of the first transmission member 1130, the two initial positioning plates are respectively arranged on both sides of the first transmission member 1130, for positioning the pallet 5000 on the first transmission member 1130.

[0067] Combination Figure 7, after a group of pallets 5000 are placed on the first transmission member 1130 manually or mechanically, the two initial positioning plates are adjusted so that the initial positioning plates respectively press the two sides of the pallets 5000, ensuring that when the pallets 5000 move to the loading station, they are already in a preset posture. Alternatively, the spacing between the two initial positioning plates can be pre-adjusted, and when a group of pallets 5000 are placed on the first transmission member 1130, as the first transmission member 1130 is transported, when the pallets 5000 pass through the transmission channel formed by the two initial positioning plates, the posture of the pallets 5000 can be adjusted. The two initial positioning plates can be driven to move by a cylinder or adjusted manually.

[0068] In addition, along the conveying direction of the first conveying member 1130, an auxiliary baffle or other limiting member is provided at the downstream position of the first conveying member 1130, and the auxiliary baffle is used to limit the tray 5000 at the loading station. A relative photoelectric sensor can be provided on the first conveying member 1130 as a detection member to detect whether the tray 5000 moves to the loading station. When the tray 5000 is detected to appear at the loading station, the first conveying member 1130 stops conveying.

[0069] In order to avoid the situation where the pallet 5000 at the transfer station is stuck to the pallet 5000 located below the pallet 5000 when the transmission mechanism 1300 transmits the pallet 5000, in some embodiments, the first pallet conveying assembly 1100 also includes at least one group of auxiliary separation assemblies 1140, each group of auxiliary separation assemblies 1140 includes a separation drive 1141 and a separation plate 1142, and the separation plate 1142 is arranged at the output end of the separation drive 1141. Taking the auxiliary separation assemblies 1140 as two groups as an example, the two groups of auxiliary separation assemblies 1140 are used to press the two sides of the adjacent pallets 5000 located on the first carrier 1110 below the loading station to avoid the transmission mechanism 1300 driving two pallets 5000 to transfer at one time.

[0070] Specifically, after the first carrier 1110 lifts the pallet 5000 at the top to the transfer station, the tray separation drive 1141 drives the tray separation plate 1142 to press the pallet 5000 under the transfer station, and at the same time the transfer mechanism 1300 grabs the pallet 5000 at the transfer station. After the pallet 5000 at the transfer station is transferred away, the auxiliary tray separation assembly 1140 releases the pressure on the pallet 5000, and the first carrier 1110 continues to lift the pallet 5000 to the transfer station.

[0071] According to a further optimization scheme, the first pallet conveying assembly 1100 also includes a first sensor, which is used to detect whether the first carrier 1110 carries a pallet 5000, that is, to detect whether all the pallets 5000 on the first carrier 1110 are transferred. The sensor can be specifically arranged on the first carrier 1110 and is a photoelectric detection sensor.

[0072] In order to ensure the continuity of the production rhythm, the second pallet conveying assembly 1200 also includes an auxiliary carrier 1240 and an auxiliary driving member. The auxiliary carrier 1240 moves between an avoidance position and a carrying position through the auxiliary driving member. The avoidance position refers to the position of avoiding the second carrier 1210 and the pallet 5000 located on the second carrier 1210, and the carrying position refers to the position of carrying the pallet 5000.

[0073] When the second carrier 1210 descends from the loading station to the unloading station, the auxiliary carrier 1240 moves from the avoidance position to the carrying position and is used to carry the pallet 5000 located at the loading station. When the second carrier 1210 moves from the unloading station to the loading station, the pallet 5000 on the auxiliary carrier 1240 is transferred to the second carrier 1210, and then the auxiliary carrier 1240 moves from the carrying position to the avoidance position which does not affect the descent of the pallet 5000.

[0074] The auxiliary driving parts include but are not limited to cylinders, motors, etc. The position movement of the auxiliary bearing member 1240 between the bearing position and the avoidance position includes but is not limited to translation, rotation and a combination of the two, which will not be repeated here.

[0075] It is defined that the second carrier 1210 is provided with a first carrying surface for carrying at least one pallet 5000, and the second lifting member 1220 is used to drive the second carrier 1210 to rise and fall, so that the first carrying surface can move between a loading station for carrying one pallet 5000, an intermediate position for carrying multiple pallets 5000, and an unloading station for transmitting the pallets 5000 to downstream equipment, and along the descending direction of the second carrier 1210, the loading station, the intermediate position and the unloading station are arranged in sequence; the auxiliary carrier 1240 is provided with a second carrying surface for carrying the pallet 5000. When the second carrier 1210 is in the unloading station, the auxiliary carrier 1240 is in the carrying position, and the second carrying surface is located above the first carrying surface and is in a carrying state capable of carrying the pallet 5000; when the second carrier 1210 is in the loading station and the auxiliary carrier 1240 is in the carrying position, the second carrying surface is located below the first carrying surface and is in an unloaded state or the first carrying surface is flush with the second carrying surface, and the second carrier 1210 and the auxiliary carrier 1240 jointly carry the pallet 5000; when the second carrier 1210 is in the middle position, the auxiliary carrier 1240 is in an avoidance position to avoid the second carrier 1210 and the pallet 5000 located on the second carrier 1210.

[0076] In the specific unloading process of the pallet 5000, in the initial situation, the auxiliary carrier 1240 is in the avoidance position, and the second carrier 1210 is in the loading station. When the first pallet 5000 is transferred to the loading station by the conveying mechanism 1300, it is carried by the second carrier 1210 located at the loading station. After the loading is completed, the second carrier 1210 moves down to the middle position. After the second pallet 5000 is moved to the loading station by the conveying mechanism 1300, the second pallet 5000 is also carried by the second carrier 1210 and stacked on top of the first pallet 5000 on the second carrier 1210. Then the second carrier 1210 repeats the above process, gradually descends, and continues to support more pallets 5000. After the second carrier 1210 supports a preset number of pallets 5000, the second carrier 1210 moves down to the unloading station. The second transmission member 1230 is provided with a conveying surface for conveying the pallet 5000. When the second lifting member 1220 is in the unloading station, the first bearing surface is below the conveying surface. At this time, the auxiliary bearing member 1240 moves from the avoidance position to the bearing position to support the next pallet 5000 transferred by the transmission mechanism 1300 through the second bearing surface, thereby ensuring the consistency and continuity of the production rhythm. After the second carrier 1210 transfers all the pallets 5000 it carries to the second transmission member 1230 at the unloading station, the second carrier 1210 moves to the loading station again, and during the process of the second carrier 1210 rising to the loading station, it can lift a pallet 5000 on the auxiliary carrier 1240 and carry it on its first carrying surface, so that the auxiliary carrier 1240 is in an empty state or the second carrier 1210 rises to a position where it can support the pallet 5000 on the auxiliary carrier 1240 together with the auxiliary carrier 1240, and then the auxiliary carrier 1240 moves to a evasive position through the auxiliary driving member, without affecting the second carrier 1210 and the pallet 5000 on the second carrier 1210. Repeat the above process to achieve uninterrupted unloading of pallets 5000.

[0077] The middle position of the second carrier 1210 actually includes multiple positions. According to the number of pallets 5000 that the second carrier 1210 can actually carry or the number of pallets 5000 that the second carrier 1210 can carry, the second carrier 1210 is sequentially lowered to ensure that the transmission mechanism 1300 can sequentially stack multiple pallets 5000 on the second carrier 1210 at the loading station. The material detection device disclosed in the present invention realizes uninterrupted unloading of pallets 5000 through the setting of the auxiliary carrier 1240, ensures production efficiency, and has a simple structure.

[0078] The first pallet conveying assembly 1100, the second pallet conveying assembly 1200 and the transmission mechanism 1300 can be arranged on the ground or on a frame through a bracket. The first lifting member 1120 and the second lifting member 1220 can specifically be a lifting screw mechanism, a cylinder slider mechanism, etc. The first transmission member 1130 and the second transmission member 1230 can be a conveyor belt.

[0079] In addition, a sensor can be provided through the bracket to detect whether the tray 5000 is fed to the loading station. When the feeding of the tray 5000 is detected, the second carrier 1210 is driven downward by the second lifting member 1220 .

[0080] Typically, the first transmission member 1130 has two stations for simultaneously placing two groups of pallets 5000, one of which is used as a material preparation station, and the other is used as a loading station. The first transmission member 1130 drives the pallets 5000 to move from the material preparation station to the loading station to ensure a continuous supply of pallets 5000.

[0081] Correspondingly, the second transmission member 1230 has two stations for placing two groups of pallets 5000 at the same time, one of which is used as a material unloading station, and the other is used as a docking station for docking with downstream equipment. The second transmission member 1230 drives the pallet 5000 to move from the material unloading station to the docking station.

[0082] In order to ensure the accuracy of the placement of material 6000 on the pallet 5000, taking the example of the pallet 5000 being placed with material 6000 at the loading station, the second pallet conveying assembly 1200 disclosed in the present invention also includes a centering positioning assembly, which is used to center the pallet 5000 located at the loading station along two directions perpendicular to each other. After the positioning is completed, the material 6000 is loaded onto the pallet 5000. After the loading is completed, the pallet 5000 is driven downward by the second carrier 1210, and the new pallet 5000 is transferred to the loading station by the transmission mechanism 1300 for the next round of pallet 5000 positioning and material loading.

[0083] Specifically, the centering positioning assembly includes a reference positioning plate 1251, a first positioning baffle 1250 and a first positioning motor. The first positioning baffle 1250 is arranged at the output end of the first positioning motor, and the first positioning motor is used to push the first positioning baffle 1250 in a direction close to or away from the reference positioning plate 1251. The tray 5000 is located between the reference positioning plate 1251 and the first positioning baffle 1250. The reference positioning plate 1251 and the first positioning baffle 1250 are used to press and position the tray 5000 on both sides along the first direction.

[0084] In addition, the centering positioning assembly also includes two second positioning baffles 1252 and two second positioning motors. The second positioning baffles 1252 are arranged one by one at the output end of the second positioning motor, and the second positioning motors are used to push the corresponding second positioning baffles 1252 to move closer to or away from each other. The tray 5000 is located between the two second positioning baffles 1252. The two second positioning baffles 1252 are used to press and position the two sides of the tray 5000 along the second direction. The first direction and the second direction are perpendicular, and the second direction and the second direction are perpendicular. Figure 5 , that is, the moving directions of the first positioning baffle 1250 and the second positioning baffle 1252 are perpendicular to each other, so as to respectively position the length direction and the width direction of the pallet 5000. The scheme of setting the reference positioning plate 1251, the first positioning baffle 1250 and the second positioning baffle 1252 together can realize the calibration of pallets 5000 of different sizes, and effectively ensure the accuracy of the position of the pallet 5000, thereby ensuring the accuracy of the placement position of the material 6000.

[0085] A protrusion is protruded from the edge of the bearing surface of the tray 5000, and the protrusion can be used for the centering positioning component to perform compression positioning, and for the conveying mechanism 1300 to perform adsorption and conveying. In addition, it can also prevent the material 6000 in the tray 5000 from falling.

[0086] In a specific embodiment, in combination Figure 6 The second lifting member 1220 and the auxiliary supporting member 1240 are respectively arranged on both sides of the pallet 5000 located on the loading station through brackets, and the reference positioning plate 1251 and the second lifting member 1220 are arranged on the same side of the pallet 5000 and on the same bracket, and the first positioning motor and the auxiliary supporting member 1240 are arranged on the same side of the pallet 5000 and on the same bracket.

[0087] Combination Figure 5 The second carrier 1210 includes at least two first support members, each of which constitutes a first bearing surface. The auxiliary carrier 1240 includes at least two second support members, each of which constitutes a second bearing surface. When the auxiliary carrier 1240 is in the bearing position, the first support members and the second support members are staggered along the lifting direction of the second lifting member 1220, so that when the first support member is lifted and moved from the unloading station to the loading station, it can be staggered with the auxiliary carrier 1240 and correspondingly support the pallet 5000 located on the auxiliary support member.

[0088] In addition to being arranged on the same bracket as the first positioning motor, the auxiliary bearing member 1240 can also be arranged on the same bracket as the second positioning motor. Correspondingly, two groups of auxiliary bearing members 1240 are also arranged and supported by the two ends of the tray 5000 respectively.

[0089] Further optimize the solution, combined with Figure 6 , by adjusting the installation position of the auxiliary driving component on the bracket, the auxiliary load-bearing of pallets 5000 of different sizes can be adapted.

[0090] In some embodiments, the transfer station and the loading station are on the same horizontal plane, and the transfer mechanism 1300 includes a first guide rail, a sliding bracket and a first suction cup. The two ends of the first guide rail extend to the transfer station and the loading station respectively. The sliding bracket is movably disposed on the first guide rail, and the first suction cup is disposed on the sliding bracket for sucking the tray 5000. Figure 2 The sliding bracket can be in an I-shape, so that the suction cup can respectively adsorb the four corners of the tray 5000.

[0091] In some embodiments, in combination Figure 8 The unloading robot arm 1400 includes a second guide rail 1420 and a robot 1410. One end of the guide rail 1420 extends to the NG material unloading module and the loading station or loading station of the OK material unloading module, and the other end extends to the carrier. The robot 1410 is slidably arranged on the guide rail 1420 and can slide along the guide rail 1420. A suction cup 1411 and / or a supporting plate 1412 are arranged on the robot 1410. The suction cup 1411 can adsorb the upper surface of the material 6000, and the supporting plate 1412 can be supported on the bottom of the material 6000 to prevent the material 6000 from falling. The robot 1410 can transfer the qualified material 6000 detected on the carrier to the tray 5000 at the loading station or the loading station along the guide rail 1420, and transfer the unqualified material 6000 to the NG material unloading module.

[0092] Combination Fig. 9 and Fig.10 The material loading module disclosed in the present invention includes a transmission component 2100, a guiding mechanism and a positioning mechanism. The transmission component 2100 is used to transmit the material 6000. The guiding mechanism is arranged on the transmission component 2100 and is used to guide the material 6000 from the initial posture when the material is fed to the intermediate posture; the positioning mechanism is arranged on the transmission component 2100 and is arranged along the conveying direction ( Fig. 9 and Fig.10 The positioning mechanism is arranged downstream of the guiding mechanism, and the positioning mechanism is used to adjust the material 6000 from the intermediate posture to the preset posture, and the loading robot arm is used to grab the material 6000 in the preset posture.

[0093] The material 6000 is transmitted at intervals on the transmission component 2100. When the material 6000 is received on the transmission component 2100, the material 6000 passes through the guiding mechanism and the positioning mechanism in sequence along the conveying direction of the transmission component 2100. At the guiding mechanism, the incoming material 6000 with different postures (initial posture) is guided by the guiding mechanism into an intermediate posture that is convenient for the positioning mechanism to position. When the material 6000 continues to be conveyed to the positioning mechanism, the positioning mechanism can position the material 6000 and further adjust the material 6000 from the intermediate posture to the preset posture, so as to facilitate the subsequent transfer or grasping of the material 6000 in a uniform preset posture.

[0094] The material loading module disclosed in the present invention can accurately guide and position the material 6000 during the loading process of the material 6000, realize automatic adjustment of the posture of the material 6000, and ensure the smooth progress of subsequent processes such as material 6000 detection.

[0095] Take the material 6000 as an example, which is a cubic backlight module. Figure 8 One end of the backlight module has a connection terminal (or a structure such as a flexible printed circuit board), and the guiding mechanism can roughly guide the backlight module to an intermediate posture in which the end with the connection terminal is closer to the upstream position and the end without the connection terminal is closer to the downstream position. The two sides of the backlight module can cooperate with the positioning mechanism to achieve posture adjustment from the intermediate posture to the preset posture.

[0096] The above-mentioned transmission assembly 2100 specifically includes a conveyor belt and a bracket. The material 6000 is transmitted on the conveyor belt, and the conveyor belt is supported on the ground or a frame through the bracket. The guiding mechanism and the positioning mechanism are both arranged on the bracket, and do not affect the conveying of the conveyor belt.

[0097] Combination Figure 8 and Fig. 9 In one embodiment, the guiding mechanism includes a guiding bridge 2200 and a guiding member 2210. The guiding bridge 2200 is supported above the transmission assembly 2100 and does not affect the transmission assembly 2100 for conveying the material 6000. The guiding bridge 2200 is provided with a first adjustment slot 2201, which is arranged along the extension direction of the guiding bridge 2200. The guiding member 2210 is adjustably fixed on the guiding bridge 2200 through the first adjustment slot 2201, and the guiding member 2210 is used to guide the material 6000 to the above-mentioned intermediate posture.

[0098] The installation position of the guide member 2210 can be adjusted through the first adjustment slot 2201, so that the guide member 2210 is set on the actual transmission path of the material 6000, so that the material 6000 in the initial posture can be pushed to adjust to the intermediate posture. Fig. 9, the guiding member 2210 can specifically be a rod-shaped member, and one end of the guiding member 2210 for pushing the material 6000 to adjust its posture is an arc structure to avoid damaging the material 6000 during the process of adjusting the posture of the material 6000.

[0099] Among them, the guiding bridge 2200 is usually arranged perpendicular to the conveying direction of the conveying component 2100. The first adjustment slot 2201 can be one or multiple arranged in parallel. When there are multiple, they can be fixed to different positions of the guiding member 2210 respectively to adjust the posture of the guiding member 2210.

[0100] In an embodiment, combined with Fig. 9 , the guiding member 2210 is generally in a shape similar to a "C", and the opening is arranged towards the conveying surface of the conveying component 2100. Specifically, the guiding member 2210 includes a connecting portion and two guiding portions. The connecting portion is adjustably fixed on the guiding bridge 2200 through the first adjustment slot 2201. The two guiding portions are respectively connected to both ends of the connecting portion and are arranged on the conveying surface of the conveying component 2100. The guiding portions are used to guide the material 6000 from the initial posture to the intermediate posture. Among them, the connecting portion and the guiding portion are usually perpendicularly arranged, and the connecting portion and the guiding portion can be an integral structure and are prepared by bending steel plates or the like.

[0101] In order to ensure the accurate positioning of the material 6000, in a specific embodiment disclosed in the present invention, the positioning mechanism includes a rough positioning component and a fine positioning component. Along the conveying direction of the conveying component 2100, the rough positioning component is arranged upstream of the fine positioning component. Among them, the rough positioning component is used to perform rough positioning on the material 6000, and the fine positioning component is used to perform fine positioning on the material 6000 and adjust it to a preset posture.

[0102] Specifically, the rough positioning component includes a positioning bridge 2300 and two first positioning members 2310. The positioning bridge 2300 is supported above the conveying component 2100 without affecting the conveying of the material 6000 by the conveying component 2100. The first positioning members 2310 are arranged on the positioning bridge 2300, and the placement angle on the conveying surface of the conveying component 2100 is adjustable. The first positioning members 2310 are provided with guiding surfaces, and a guiding channel for the material 6000 to pass through and guide the material 6000 is formed between the guiding surfaces of the two first positioning members 2310. Along the conveying direction of the conveying component 2100, the width of the guiding channel gradually narrows ( Figure 8 the first positioning member 2310 in [[ ]] has not been adjusted).

[0103] After the material 6000 is guided by the guide member 2210, the material 6000 is in an intermediate posture that is convenient for passing through the guiding channel, and can effectively prevent the material 6000 from being blocked in the guiding channel. At the same time, during the transmission process in the guiding channel, the material 6000 can further adjust its posture under the action of the guiding surface. Usually, the width of the guiding channel at the exit position is slightly larger than the width of the material 6000 (the maximum dimension perpendicular to the conveying direction of the transmission component 2100 when the material 6000 is in a preset posture).

[0104] In order to facilitate the entry and exit of material 6000 in the guiding channel, combined with Figure 8 Along the conveying direction of the transmission component 2100, the two ends of the guide front side are arc-shaped guide structures inclined in the direction opposite to the guide channel. The arc-shaped guide structure can also play a guiding effect on the material 6000.

[0105] In order to facilitate the adjustment of the shape and size of the guiding channel according to the material 6000, a second adjustment groove 2301 is provided on the positioning bridge 2300. The second adjustment groove 2301 is arranged along the extension direction of the positioning bridge 2300. The first positioning member 2310 is adjustably fixed on the guiding bridge 2200 through the second adjustment groove 2301 to be able to adjust the size of the guiding channel. At the same time, the first positioning member 2310 can be rotated relative to the second adjustment groove 2301 to adjust the shape of the guiding channel.

[0106] The positioning bridge 2300 is usually arranged perpendicular to the conveying direction of the transmission assembly 2100. The second adjustment slot 2301 can be one or multiple arranged in parallel. When there are multiple, they can be fixed to different positions of the first positioning member 2310 respectively to adjust the posture of the first positioning member 2310.

[0107] For ease of description, taking the conveying plane of the conveyor belt as a plane reference, the conveying direction of the transmission component 2100 is a first direction, and the direction perpendicular to the conveying direction of the transmission component 2100 is a second direction.

[0108] In a specific embodiment disclosed in the present invention, the precision positioning assembly includes two sets of push assemblies, combined with Fig. 9 The pushing assembly includes a positioning drive member 2400 and a second positioning member 2410. The positioning drive member 2400 is arranged on the transmission assembly 2100, and the second positioning member 2410 is arranged at the output end of the positioning drive member 2400. The positioning drive member 2400 is used to push the second positioning member 2410 to move along the second direction; the second positioning members 2410 of the two groups of pushing assemblies are used to push the two sides of the material 6000 respectively in a direction perpendicular to the conveying direction under the action of their respective positioning drive members 2400.

[0109] When the material 6000 moves to the position of the precision positioning component, the positioning drive 2400 drives the two second positioning components 2410 to push on both sides of the material 6000 respectively to adjust the posture of the material 6000. After the adjustment is completed, the positioning drive 2400 drives the second positioning components 2410 to retract, and the material 6000 continues to be transmitted to the downstream by the transmission component 2100.

[0110] Combination Figure 8 The upstream end of the second positioning member 2410 can be configured as an open structure that is open in the upstream direction. During the process of the fine positioning assembly guiding the material 6000, the transmission assembly 2100 can be stopped or not.

[0111] In another embodiment disclosed in the present invention, the precision positioning assembly includes a lifting positioning plate 2430, a lifting drive 2420, a positioning drive 2400 and a second positioning member 2410. The positioning drive 2400 and the lifting drive 2420 are both arranged on the transmission assembly 2100. The second positioning member 2410 is arranged at the output end of the positioning drive 2400, and is used to push the second positioning member 2410 to move along the second direction. The lifting positioning plate 2430 is arranged at the output end of the lifting drive 2420. The lifting drive 2420 is used to drive the lifting positioning plate 2430 to move in a direction perpendicular to the conveying plane of the conveyor belt (usually a vertical direction). Specifically, the lifting positioning plate 2430 moves between the positioning position and the avoidance position. The material 6000 is used to pass between the second positioning member 2410 and the lifting positioning plate 2430.

[0112] When the material 6000 is conveyed to the position where the above-mentioned precise positioning component is located, the lifting and positioning plate 2430 is driven by the lifting drive 2420 to descend to the positioning position, and the positioning drive 2400 drives the second positioning member 2410 to move along the second direction toward the direction of the lifting and positioning plate 2430 until the material 6000 is pushed tightly against the plate surface of the lifting and positioning plate 2430 facing the second positioning member 2410, thereby achieving precise adjustment of the material 6000. After the adjustment is completed, the lifting and positioning plate 2430 is raised in the vertical direction by the lifting drive 2420 to a avoidance position that does not affect the conveying of the material 6000, and the positioning drive 2400 synchronously drives the second positioning member 2410 to retreat, and the material 6000 continues to be conveyed downstream.

[0113] In some embodiments, two sets of guiding mechanisms and positioning mechanisms can be simultaneously arranged on a set of transmission components 2100, and two rows of materials 6000 can be transported and positioned at the same time. Fig.10The lifting and positioning plates 2430 of the two positioning mechanisms can be shared, and the two columns of materials 6000 are staggered and transported on the transmission component 2100. Correspondingly, the two positioning mechanisms are staggered along the conveying direction. When one material 6000 in each of the two columns of materials 6000 moves to its respective precision positioning component, the two groups of precision positioning components act simultaneously to position the material 6000. After the positioning is completed, the two columns of materials 6000 are transported to the downstream and transferred in sequence.

[0114] The second positioning member 2410 and the lifting positioning plate 2430 mentioned above can both be plate-shaped members, and the lifting driving member 2420 and the positioning driving member 2400 can both be cylinders.

[0115] The transfer of the material 6000 between the transmission component 2100 (material loading module) and the carrier is realized by the loading robot arm. In order to ensure the consistency of the posture of the material 6000 in the subsequent inspection process, a third positioning member 2110 for contacting the material 6000 is provided at the downstream end of the transmission component 2100, and the third positioning member 2110 is provided downstream of the positioning mechanism along the conveying direction of the transmission component 2100. When the material 6000 is conveyed by the transmission component 2100 to the position where the third positioning member 2110 is located, the material 6000 cannot be moved further due to the influence of the third positioning member 2110 (the end of the backlight module without the wiring terminal is in contact with the third positioning member 2110), and can be grasped by the robot arm for the transportation of the material 6000. Exemplarily, the third positioning member 2110 can be a plate-shaped member.

[0116] The transmission component 2100 is provided with a detection component 2120, and the detection component 2120 is used to detect whether the material 6000 is in a transfer position for transferring the material 6000. Specifically, the detection component 2120 can be provided on the third positioning member 2110 or the bracket of the transmission component 2100 to detect whether the material 6000 is conveyed to the third positioning member 2110. The detection component 2120 can be a distance sensor or a photoelectric switch.

[0117] In addition, a detection component 2120 can be provided between the coarse positioning component and the fine positioning component, and the detection component 2120 is used to detect whether there is material at the fine positioning component, and when the material is detected, the fine positioning component starts the positioning action. The detection component 2120 can be a distance sensor, a photoelectric switch, or an optical fiber.

[0118] According to the posture of the material 6000 on the material loading module, the loading robot arm can use structures such as clamps or suction cups to transfer the material 6000, and the unloading robot arm 1400 usually uses the same structure as the loading robot arm.

[0119] For the material 6000 on the carrier, the detection surface of the material 6000 needs to be arranged toward the visual detection submodule. For example, if the visual detection submodule is arranged in the carrier, and the detection surface of the material 6000 on the carrier needs to be arranged toward the carrier, if the material 6000 is in the material loading module, the detection surface is arranged toward the conveyor belt of the material loading module, then the loading robot can keep the material 6000 facing the material loading module and move it to the carrier. If the material 6000 is in the material loading module, the detection surface is arranged away from the conveyor belt of the material loading module, then a flip mechanism is provided on the loading robot arm, and the flip mechanism is used to drive the loading robot arm to flip, so as to flip the material 6000 to the detection surface facing downward during the transfer of the material 6000, and then place it on the carrier for detection. Alternatively, a flip robot arm can be provided separately, and the detection surface of the material 6000 on the carrier can be flipped by the flip robot arm to face the visual detection submodule.

[0120] In other embodiments, the inspection surface of the material 6000 located on the carrying position of the carrier needs to be arranged upward for inspection by the visual inspection sub-module located on the top of the carrying position of the carrier, while the material 6000 on the OK material unloading module needs to be arranged with the back of the inspection surface facing upward to facilitate subsequent processes. Therefore, after the visual inspection sub-module completes the inspection of the material 6000 on the carrier, the material 6000 needs to be flipped over by a flipping robot arm so that the back of the inspection surface faces upward, and then the material 6000 is transferred to the OK material unloading module or the NG material unloading module with the back of the inspection surface facing upward by the unloading robot arm 1400.

[0121] Specifically, the flipping robot arm can use suction cup adsorption, claw clamping and other methods to drive the material 6000 to flip. Taking the flipping robot arm with a suction cup capable of adsorbing material 6000 as an example, after the material 6000 is inspected by the visual inspection sub-module, the suction cup of the flipping robot arm can adsorb the inspection surface of the material 6000. After the adsorption is completed, the flipping robot arm can drive the material 6000 to flip 180° so that the back of the inspection surface of the material 6000 faces upward. At this time, the suction cup releases the adsorption of the material 6000, and the unloading robot arm 1400 can transfer the material 6000 on the flipping robot arm to the OK material unloading module or the NG material unloading module.

[0122] After the flipping robot arm drives the material 6000 to flip, the material 6000 is in the unloading position, which avoids the carrier and has enough space for the unloading robot arm 1400 to transfer the material 6000.

[0123] The above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present invention. Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
