[0045] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0046] like Figure 1 and Figure 2 As shown, the present invention provides a glass online sampling and detection system for a glass production line, which can be connected to the control system of the glass production line by wired communication or wireless communication; the glass online sampling and detection system includes a sampling transmission device 1 and a glass detection device; the sampling transmission device 1 includes a first conveying mechanism 11, a second conveying mechanism 12 and a first lifting mechanism 13, and one of the first conveying mechanism 11 and the second conveying mechanism 12 is a roller conveying mechanism, and the other is a belt conveying mechanism.

[0047] Specifically, if Figure 1 and Figure 2 As shown, the first conveying mechanism 11 is arranged between the drop plate area and the lower plate area of ​​the glass production line, and is used to convey the glass 01 horizontally along the first direction, so that the glass 01 moves toward the lower plate area; the second conveying mechanism 12 is used to convey the glass 01 horizontally along the second direction, and the first direction is perpendicular to the second direction; the first lifting mechanism 13 is used to drive the second conveying mechanism 12 to move up and down, so that the second conveying mechanism 12 lifts the glass 01 on the first conveying mechanism 11 or puts the glass 01 on the second conveying mechanism 12 down to the first conveying mechanism 11; when the second conveying mechanism When the glass 01 on the first conveying mechanism 11 is lifted by the first conveying mechanism 12, a conveying space for the glass 01 to be normally conveyed along the first direction is formed between the first conveying mechanism 11 and the second conveying mechanism 12; the glass detection device is arranged beside the sampling and transmission device 1, and is used to detect the glass 01 transmitted by the second conveying mechanism 12, and return the detected glass 01 to the second conveying mechanism 12, so that the detected glass 01 can be lowered to the first conveying mechanism 11 through the second conveying mechanism 12, so that the detected glass can be returned to the glass production line through the first conveying mechanism 11.

[0048] The glass online sampling and detection system involved in the present invention can automatically sample the glass 01 on the glass production line through the sampling and transmission device 1, and automatically reverse and transmit the sampled glass 01 to the glass detection device for automatic detection. The glass after detection can also be returned to the glass production line through the sampling and transmission device 1, thereby realizing the full automation of the glass sampling, transmission and detection process without interfering with the glass production line, which not only improves the accuracy and efficiency of glass detection, but also greatly reduces the number of detection personnel, the labor intensity of detection personnel, and the glass loss and missed detection caused by manual detection, thereby achieving the purpose of reducing costs and increasing efficiency.

[0049] For the convenience of description, the first direction is defined as the X direction in the drawings, and the second direction is defined as the Y direction in the drawings. Based on this, the Z direction in the drawings is the up-down direction.

[0050] Since one of the first conveying mechanism 11 and the second conveying mechanism 12 is a roller conveying mechanism and the other is a belt conveying mechanism, the sampling and transmission device 1 has the following two embodiments:

[0051] Embodiment 1:

[0052] like Figure 2 As shown, the first conveying mechanism 11 is a roller conveying mechanism, which includes a plurality of conveying rollers spaced apart along a first direction, and each conveying roller rotates synchronously; the second conveying mechanism 12 is a belt conveying mechanism installed on a first lifting mechanism 13, which includes a plurality of belt conveying assemblies spaced apart along a first direction, and each belt conveying assemblies transmits synchronously; wherein, the conveying rollers of the first conveying mechanism 11 and the belt conveying assemblies of the second conveying mechanism 12 are staggered in the first direction; in this way, the first lifting mechanism 13 can be used to move the conveying surface of the second conveying mechanism 12 above the conveying surface of the first conveying mechanism 11 or to move the conveying surface of the second conveying mechanism 12 below the conveying surface of the first conveying mechanism 11.

[0053] Embodiment 2:

[0054] The first conveying mechanism 11 is a belt conveying mechanism, which includes a plurality of belt conveying assemblies spaced apart along a first direction, and each belt conveying assemblies transmit synchronously; the second conveying mechanism 12 is a roller conveying mechanism installed on the first lifting mechanism 13, which includes a plurality of conveying rollers spaced apart along the first direction, and each conveying roller rotates synchronously; wherein the belt conveying assemblies of the first conveying mechanism 11 and the conveying rollers of the second conveying mechanism 12 are staggered in the first direction; in this way, the first lifting mechanism 13 can be used to move the conveying surface of the second conveying mechanism 12 above the conveying surface of the first conveying mechanism 11 or to move the conveying surface of the second conveying mechanism 12 below the conveying surface of the first conveying mechanism 11.

[0055] It can be understood that the synchronous rotation of each conveyor roller in the roller conveyor mechanism can be centrally controlled by the same drive source or individually controlled by different drive sources; similarly, the synchronous transmission of each belt conveyor component in the belt conveyor mechanism can also be centrally controlled by the same drive source or individually controlled by different drive sources; based on the control difficulty and control cost considerations, in this embodiment, the rotation of each conveyor roller in the roller conveyor mechanism is preferably controlled by a single drive source, and the synchronous transmission of each belt conveyor component in the belt conveyor mechanism is also preferably controlled by a single drive source.

[0056] It should be noted that the first lifting mechanism 13 has various structural forms, including but not limited to various lifting mechanisms that can achieve height adjustment, such as scissors-type lifts, ball screw lifts, or rack and pinion lifts. There is no limitation on this, as long as it can meet the lifting requirements.

[0057] like Figure 1 and Figure 4 As shown, the glass inspection device includes an appearance inspection and conveying device 2; the appearance inspection and conveying device 2 includes a third conveying mechanism 21, a horizontal position adjustment mechanism 24 and an optical inspection device 25; wherein the third conveying mechanism 21 is used to dock with the second conveying mechanism 12 to receive and convey the glass 01 transmitted by the second conveying mechanism 12 along the second direction; the horizontal position adjustment mechanism 24 is installed on the fixed frame 23, and is used to adjust the position of the optical inspection device 25 to perform appearance inspection on the glass 01 on the third conveying mechanism 21.

[0058] like Figure 4 As shown, the horizontal position adjustment mechanism 24 includes a first horizontal position adjustment mechanism 241 and a second horizontal position adjustment mechanism 242; the first horizontal position adjustment mechanism 241 is installed on the fixing frame 23, and the second horizontal position adjustment mechanism 242 is installed above the first horizontal position adjustment mechanism 241; wherein, the first horizontal position adjustment mechanism 241 is used to adjust the position of the second horizontal position adjustment mechanism 242 in the second direction, and the second horizontal position adjustment mechanism 242 is used to adjust the position of the optical detection device 25 in the first direction.

[0059] It should be noted that the first horizontal position adjustment mechanism 241 and the second horizontal position adjustment mechanism 242 are various existing mechanisms that can achieve position adjustment in a specific direction, and are not limited to this; in this embodiment, the first horizontal position adjustment mechanism 241 and the second horizontal position adjustment mechanism 242 are preferably screw adjustment mechanisms.

[0060] In this embodiment, the optical detection device 25 is a laser displacement sensor; when in use, the horizontal position adjustment mechanism 24 drives the laser displacement sensor to scan the entire glass to be inspected, obtains appearance information such as the thickness, length, width, diagonal size and warping of the glass 01, and completes the appearance inspection of the glass 01.

[0061] Of course, in other embodiments, the optical detection device 25 may also be an integration of one or more sensors among various detection sensors such as an image acquisition sensor, a thickness measurement sensor, and a transmittance detection sensor.

[0062] In a preferred embodiment, if Figure 4 As shown, the appearance inspection conveying device also includes a support platform 231 and a second lifting mechanism 22; wherein the support platform 231 is mounted on the fixing frame 23, and a avoidance hole 2311 is provided on the support platform 231 for the third conveying mechanism 21 to move up and down; the second lifting mechanism 22 is arranged below the third conveying mechanism 21, and is used to drive the third conveying mechanism 21 to move up and down, so as to place the glass 01 on the third conveying mechanism 21 on the support platform 231 or to make the third conveying mechanism 21 lift the glass 01 on the support platform 231; the horizontal position adjustment mechanism 24 is installed on the support platform 231, and is used to adjust the position of the optical inspection device 25, so as to perform appearance inspection on the glass 01 on the support platform 231. The support platform 231 can not only stably support the glass 01, but also act as a light shielding member to reduce the interference of external light sources on the laser, and ensure the accuracy of the appearance inspection of the glass 01.

[0063] It can be understood that the third conveying mechanism 21 is a roller conveying mechanism or a belt conveying mechanism, which is not limited thereto; in the present embodiment, the second conveying mechanism 21 is preferably a belt conveying mechanism.

[0064] Specifically, if Figure 4 and Figure 5 As shown, the second conveying mechanism includes multiple rows of belt conveying assemblies 21a spaced apart along the first direction; the belt conveying assembly 21a includes a belt bracket 211, a belt 212, a driving wheel 213, a driven wheel 214 and a first transition wheel 215; the driving wheel 213, the driven wheel 214 and the first transition wheel 215 are all rotatably mounted on the belt bracket 211, and the belt 212 is sleeved on the driving wheel 213, the driven wheel 214 and the first transition wheel 215; wherein the driven wheel 213 and the first transition wheel 215 are spaced apart in the second direction, and the belt between the driven wheel 213 and the first transition wheel 215 is a conveying section for supporting and conveying the glass 01; the driving wheel 213 is located below the conveying section, and is used to be connected to a driving source.

[0065] Alternatively, if Figure 5As shown, the belt transmission assembly 21a further includes a second transition wheel 216; the second transition wheel 216 is located between the conveying section and the driving wheel 213 to lift the belt between the driving wheel 213 and the driven wheel 214, thereby increasing the contact area between the driving wheel 213, the driven wheel 214 and the belt 212, reducing or avoiding slippage; in addition, the second transition wheel 216 can also serve as a tensioning wheel to achieve belt tensioning. Of course, the belt tensioning can also be achieved by adjusting the position of the driven wheel 214 or the first transition wheel 215 in the second direction.

[0066] like Figure 6 and Figure 7 As shown, the second lifting mechanism 22 includes a belt lifting frame 221 and a bottom frame 222; the belt lifting frame 221 is used to install the second conveying mechanism; a plurality of first horizontal support rods 223 are installed on the top of the bottom frame 222 for rotation at intervals along the first direction or the second direction; first swing arms 224 are fixed at both ends of the first horizontal support rods 223, and each first swing arm 224 is hinged to the bottom of the belt lifting frame 221, so that the first horizontal support rod 223, the first swing arms 224 at both ends of the first horizontal support rod 223 and the belt lifting frame 221 together form a parallelogram lifting component; the first swing arms 224 at the same end of each first horizontal support rod 223 are connected by a first pull rod 226, and a first driving component 225 for driving any first swing arm 224 to swing or any first horizontal support rod 223 to rotate is provided on the bottom frame 222; in this way, each first swing arm 224 can rotate synchronously, thereby causing the belt lifting frame 221 to rise and fall.

[0067] It can be understood that when the first drive component 225 is hinged to the first swing arm 224, the first drive component 225 is a linear drive device such as an electric push rod hinged on the bottom frame 222 or a crank rocker mechanism installed on the bottom frame 222, without limitation; when the first drive component 225 is connected to the first horizontal support rod 223, the first drive component 225 can be an integration of a motor and a gear transmission mechanism or a belt transmission mechanism.

[0068] Of course, in other embodiments, the second lifting mechanism 22 may also be replaced by a lifting mechanism of other structural forms such as a scissor-type lifting platform or a screw lifting platform.

[0069] In a further embodiment, Figure 4As shown, the appearance inspection conveying device includes at least one glass stopper 261 arranged at intervals along the first direction, and the glass stopper 261 is located on the side away from the second conveying mechanism 12; wherein the glass stopper 261 moves up and down under the action of the third lifting mechanism 262 to switch between the stop position and the avoidance position. When the glass stopper 261 is at the stop position, the glass 01 on the third conveying mechanism 21 can be stopped and corrected to avoid the problem that part of the glass cannot be inspected outside the inspection area during the subsequent appearance inspection process; when the glass stopper 261 moves up to the avoidance position, the glass 01 can be smoothly conveyed to the next process through the third conveying mechanism 21.

[0070] Specifically, the glass stopper 261 includes a mounting bracket and a support wheel; wherein the support wheel is vertically rotatably mounted on the mounting bracket, and the mounting bracket is connected to the third lifting mechanism 262; of course, the support wheel can also be replaced by a baffle fixed on the mounting bracket.

[0071] It is understandable that the third lifting mechanism 262 is a linear drive device such as an electric push rod or a cylinder, and this is not limited to this.

[0072] Of course, in a preferred embodiment, in order to ensure the stable transmission of the glass 01 between each process, Figure 4 As shown, an auxiliary conveying roller 27 is arranged at each end of the appearance inspection device 2 in the second direction to ensure the stability of conveying.

[0073] In a further embodiment, Figure 3 and Figure 8 As shown, the glass detection device includes a weighing and conveying device 3; the weighing and conveying device 3 includes a fourth conveying mechanism 31, a fourth lifting mechanism 32 and a weighing bracket 33; the weighing bracket 33 is located below the fourth conveying mechanism 31, and a plurality of vertical support rods 33a for supporting the glass 01 are arranged on the weighing bracket 33; the fourth conveying mechanism 31 is used to receive the glass 01 transmitted by the third conveying mechanism 21; the fourth lifting mechanism 32 is used to drive the fourth conveying mechanism 31 to move up and down, so as to place the glass 01 on the fourth conveying mechanism 31 on the vertical support rods 33a or lift the glass 01 on the vertical support rods 33a.

[0074] It is understandable that the fourth conveying mechanism 31 is a roller conveying mechanism or a belt conveying mechanism, and there is no limitation on this, as long as it is ensured that there is a gap for the vertical support rod 33a to pass through; in this embodiment, the fourth conveying mechanism 31 is preferably a roller conveying mechanism.

[0075] Specifically, Fig. 9As shown, the fourth conveying mechanism 31 includes a plurality of conveying rollers 311 spaced apart along the second direction, and each conveying roller 311 is synchronously driven by a driving assembly. The preferred structure of the driving assembly includes a driven bevel gear 314 coaxially fixed to the same end of each conveying roller 311, a driving bevel gear 313 meshing with each driven bevel gear 314, and a driving shaft 312 coaxially connected to each driving bevel gear 313, and the driving shaft 312 can be driven directly or indirectly by a motor.

[0076] like Figure 8 and Fig.10 As shown, in order to ensure the stability of glass weighing, multiple rows of vertical support rods 33a need to be arranged at intervals along the second direction on the weighing bracket 33, and each row of vertical support rods 33a needs to be staggered with the conveying rollers 311 in the fourth conveying mechanism 31; of course, the vertical support rods 33a in the same row can also be interconnected to form a vertical support frame, as long as they do not interfere with the fourth conveying mechanism 31.

[0077] like Figure 8 and Fig. 9 As shown, the fourth lifting mechanism 32 includes a roller lifting frame 321 and a bottom mounting frame 322; the roller lifting frame 321 is used to install the conveying roller 311 and the driving assembly; a plurality of second horizontal support rods 323 are fixed at intervals along the first direction or the second direction on the top of the bottom mounting frame 322; both ends of the second horizontal support rods 323 are rotatably connected with second swing arms 324, and each second swing arm 324 is hinged to the bottom of the roller lifting frame 321, so that the second horizontal support rod 323, the second swing arms 324 at both ends of the second horizontal support rod 323 and the roller lifting frame 321 together form a parallelogram lifting assembly; the second swing arms 324 at the same end of each second horizontal support rod 323 are connected by a second pull rod 326, and the bottom mounting frame 322 is provided with a second driving assembly 325 for driving the second swing arms 324 at both ends of the second horizontal support rod 323 to rotate respectively; in this way, each second swing arm 324 can be rotated synchronously, thereby causing the roller lifting frame 321 to rise and fall.

[0078] It is understandable that the second driving assembly 325 is a linear driving device such as an electric push rod hinged on the bottom mounting frame 322.

[0079] Of course, in other embodiments, the fourth lifting mechanism 32 may also be replaced by a lifting mechanism of other structural forms such as a scissor-type lifting platform or a screw lifting platform.

[0080] In a preferred embodiment, if Figures 11 to 13As shown, the online sampling and detection system includes a storage device 4; the storage device 4 includes a storage rack 41 located outside the weighing and conveying device 3, and the top of the storage rack 41 protrudes upward from the weighing and conveying device 3; a plurality of lifting mechanisms are arranged on the storage rack 41 at intervals along the second direction, and each lifting mechanism moves synchronously; the lifting mechanism includes two lifting components and a plurality of storage rods 425 arranged at intervals from top to bottom; the two lifting components are arranged at intervals in the first direction, and the two ends of the storage rod 425 are respectively fixed on the movable parts of the corresponding two lifting components; the distance between the two adjacent storage rods 425 is greater than the lifting stroke of the fourth conveying mechanism 31.

[0081] For the convenience of description, the storage rods 425 spaced apart from top to bottom are numbered, wherein the top storage rod 425 is a first-stage storage rod, and the bottom storage rod 425 is a last-stage storage rod.

[0082] In the initial state, each storage rod 425 is located below the supporting surface formed by the top end of the vertical support rod 33a; when the weighing of the weighing bracket 33 is completed, each lifting mechanism moves synchronously to make each storage rod 425 move upward together by a first preset distance, so as to use the first-level storage rod (i.e., the top storage rod 425) to lift and store the glass 01 located on the vertical support rod 33a; at this time, the second-level storage rod is located below the supporting surface formed by the top end of the vertical support rod 33a, and a conveying space for the fourth conveying mechanism 31 to convey the glass is formed between the first-level storage rod and the second-level storage rod 425; the fourth conveying mechanism 31 moves up to the docking position to receive the glass 01 transmitted by the third conveying mechanism 21, and After the glass 01 moves to the top of the weighing bracket 33, it moves downward so that the glass 01 is placed on the vertical support rod 33a of the weighing bracket 33; after the weighing bracket 33 completes the weighing of the glass, the lifting mechanisms move synchronously to make the storage rods 425 move upward together by a first preset distance, so as to use the secondary storage rods to lift and store the glass 01 on the vertical support rod 33a; at this time, the tertiary storage rods are located below the supporting surface formed by the top of the vertical support rods 33a, and a conveying space for the fourth conveying mechanism 31 to convey the glass is formed between the secondary storage rods and the tertiary storage rods; similarly, the subsequent levels of receiving rods will also collect the weighed glass 01 in turn, thereby realizing the weighing and storage of multiple groups of glass in turn.

[0083] When the storage rods of each level of the storage device 4 have stored glass 01, it is necessary to release the glass 01. Specifically, the fourth conveying mechanism 31 is moved up to the docking position, and the storage rods 425 are moved downward together until the glass 01 on the first-level storage rod is placed on the fourth conveying mechanism 31, and the fourth conveying mechanism 31 transfers the lowered glass to the third conveying mechanism 21; when the glass 01 on the fourth conveying mechanism 31 is transferred away, the storage rods 425 are moved downward together again until the glass 01 on the second-level storage rod is placed on the fourth conveying mechanism 31, and the fourth conveying mechanism 31 transfers the lowered glass to the third conveying mechanism 21; similarly, the glass 01 on the subsequent storage rods of each level will also be placed on the fourth conveying mechanism 31 in turn, and the fourth conveying mechanism 31 transfers the lowered glass to the third conveying mechanism 21.

[0084] In a preferred embodiment, if Fig.13 As shown, the lifting mechanism includes a transmission shaft 421 rotatably supported on a material storage frame 41, and the axial direction of the transmission shaft 421 is a first direction; the lifting assembly is a synchronous transmission assembly, and the synchronous transmission assembly includes a first synchronous wheel 422, a second synchronous wheel 423 and a belt-shaped synchronous member 424 sleeved on the first synchronous wheel 422 and the second synchronous wheel 423; the first synchronous wheel 422 is coaxially mounted on the corresponding transmission shaft 421, and the two ends of the material storage rod 425 are respectively fixed on the same side of the corresponding two belt-shaped synchronous members 424.

[0085] It can be understood that the belt-shaped synchronous element 424 is a synchronous belt or a synchronous chain.

[0086] It should be noted that each transmission shaft 421 is driven by the same driving source to achieve synchronous movement of each synchronous transmission component; of course, the second synchronous wheel 423 at the same end of each transmission shaft 421 can also be driven by the same driving source to achieve synchronous movement of each synchronous transmission component; how to achieve synchronous movement of multiple transmission shafts or multiple synchronous transmission components through the same driving source is an existing technology and will not be elaborated on.

[0087] To achieve the above purpose or other purposes, the present invention further discloses a glass online sampling and detection method, which uses the above-mentioned glass online sampling and detection system to perform online sampling and detection, and the online sampling and detection system is communicatively connected with the control system of the glass production line; the glass online sampling and detection method comprises:

[0088] S1, the control system controls the first conveying mechanism 11 to move so that a group of glasses to be inspected from the drop plate area stops directly above the second conveying mechanism 12; wherein the group of glasses to be inspected includes at least one glass spaced apart along the second direction;

[0089] It should be noted that when sampling glass, the transmission speed of the first conveying mechanism 11 can be increased to distance the sampled glass from other subsequent glasses, thereby reserving sufficient time for the second conveying mechanism 12 to be lifted upward, thereby avoiding interference with the normal transmission of other glasses on the glass production line due to insufficient time for the second conveying mechanism 12 to be lifted upward.

[0090] It is understandable that when conveying glass, the glass production line usually takes groups as units. That is, a group of glass includes at least one glass arranged at intervals along the second direction. Figure 1 As shown, two pieces of glass arranged side by side on the glass production line form a group. At this time, when sampling the glass, sampling is also performed in groups to ensure the coordination between the glass online sampling and detection system and the glass production line.

[0091] S2, the control system controls the first lifting mechanism 13 to move, so as to drive the second conveying mechanism 13 to lift the glass to be inspected parked on the first conveying mechanism 11, and transfers the glass to be inspected to the appearance inspection conveying device 2 through the second conveying mechanism 13;

[0092] It should be noted that in order not to affect the normal transmission of other subsequent glasses on the glass production line; when the second conveying mechanism 13 lifts the glass to be inspected parked on the first conveying mechanism 11, a conveying space for the glass to be normally transmitted along the first direction must be formed between the second conveying mechanism 13 and the first conveying mechanism 11.

[0093] S3, the third conveying mechanism 21 in the appearance inspection conveying device 2 receives the glass to be inspected from the second conveying mechanism 13, and positions the glass to be inspected; then, the horizontal position of the optical inspection device 25 is adjusted by the horizontal position adjustment mechanism 24 to optically scan the glass to be inspected, thereby completing the appearance inspection of the glass to be inspected;

[0094] It should be noted that the glass to be inspected can be directly placed on the third conveying mechanism 21 for appearance inspection, or the third conveying mechanism 21 can be driven downward by the second lifting mechanism 22 to place the glass to be inspected on the supporting platform 231 for appearance inspection. Based on stability considerations, this embodiment preferably places the glass to be inspected on the supporting platform 231 for appearance inspection.

[0095] S4, the third conveying mechanism 21 conveys the glass to be inspected after the appearance inspection to the weighing and conveying device 3;

[0096] S5, repeating steps S1 to S4 to sample and inspect the appearance of the next group of glass; at the same time, the fourth lifting mechanism 32 in the weighing and conveying device 3 drives the fourth conveying mechanism 31 to move upward to the docking position to receive the glass to be inspected from the third conveying mechanism 21;

[0097] Since the present application receives the glass to be inspected that has completed the appearance inspection through the weighing and conveying device 3 while performing sampling and appearance inspection of the next group of glass to be inspected, the weighing and conveying of the current group of glass and the sampling and appearance inspection of the next group of glass can be performed simultaneously, which is beneficial to shortening the inspection cycle of multiple groups of glass.

[0098] S6, the fourth conveying mechanism 31 transports the glass to be inspected to the top of the weighing bracket 33; then, the fourth conveying mechanism 31 moves downward under the action of the fourth lifting mechanism 32 to lower the glass to be inspected onto the vertical support rod 33a of the weighing bracket 33 to complete the weighing test; then, the lifting mechanism in the storage device 4 controls the storage rod 425 to rise to lift and store the glass that has completed the weighing test;

[0099] In the initial state, all the storage rods 425 of the storage device 4 are located below the supporting surface formed at the top end of each vertical support rod 33a; when the glass completes the weighing test on each vertical support rod 33a, all the storage rods 425 of the storage device 4 will move up together by a first preset distance, so that the first-level storage rod (i.e., the topmost storage rod 425) lifts the glass placed on the vertical support rod 33a; at this time, except for the first-level storage rod, the remaining storage rods are all located below the supporting surface formed at the top end of each vertical support rod 33a, and a conveying space for the fourth conveying mechanism 31 to convey the glass is formed between the first-level storage rod and the second-level storage rod, preparing for the weighing, transmission and storage of the next group of glass.

[0100] S7, repeating step S6 to complete the weighing, testing and storage of multiple groups of glass in sequence;

[0101] S8, the fourth conveying mechanism 31 moves up to the docking position under the action of the fourth lifting mechanism 32; the lifting mechanism in the storage device 4 controls the storage rod 425 to descend, so as to lower the stored glass to the idle fourth conveying mechanism 31; then, the lowered glass is transmitted to the third conveying mechanism 21 via the fourth conveying mechanism 31;

[0102] This step is performed after the storage device 4 is full of glass or the glass detection quantity meets the requirements.

[0103] S9, repeat step S8 to complete the lowering of multiple groups of glass in sequence; at the same time, the third conveying mechanism 21 transfers the glass transmitted by the fourth conveying mechanism 31 to the second conveying mechanism 12, and the second conveying mechanism 12 moves downward under the action of the first lifting mechanism 13 to lower the glass on the second conveying mechanism 12 to the first conveying mechanism 11; the first conveying mechanism transfers the lowered glass in the direction close to the lower area.

[0104] The glass online sampling and testing method disclosed in the present invention can carry out centralized testing, centralized storage and centralized release and reflow of multiple groups of glass, so as to completely separate the sampling and testing of glass from the reflow of glass. Compared with the traditional solution of immediately reflowing the glass production line after sampling and testing, the present solution can not only avoid the interference between the glass in the reflow route and the glass in the sampling and testing route, but also reduce the coordination difficulty of each device and improve the testing efficiency of multiple groups of glass. In addition, the present invention enables the weighing and transmission of the current group of glass to be carried out simultaneously with the sampling and appearance testing of the next group of glass, further shortening the testing cycle of multiple groups of glass and improving the testing efficiency.

[0105] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0106] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
