Description

A connection system and method for the cold end of a photovoltaic glass production line and a deep processing production line Technical Field

[0001] The present invention relates to the technical field of glass production, and in particular to a connection system and a connection method between a cold end of a photovoltaic glass production line and a deep processing production line. Background Art

[0002] In the existing photovoltaic glass production process, the cold-end production line and the deep-processing production line operate independently. A glass unloader unloads glass sheets onto glass racks at the end of the cold-end production line. A forklift then transports the entire rack of glass to the front end of the deep-processing production line, where a loading machine loads the glass again. This method has a low degree of automation, high labor intensity, and high equipment investment costs. Typically, the output of a photovoltaic glass cold-end production line matches the processing capacity of two deep-processing production lines, with two cold-end production lines corresponding to four deep-processing production lines. However, the glass delivered by the cold-end production line is mostly center-split panels, meaning two sheets are delivered side by side, while the glass on the deep-processing production line is delivered and processed individually, making it impossible to directly connect the cold-end production line and the deep-processing production line.

[0003] Connecting the cold-end production line and the deep-processing production line is a major challenge for technicians in this field. This patent attempts to solve the problem of automatically connecting the two cold-end production lines and the four deep-processing production lines. During the connection process, two pieces of glass transported side by side are automatically converted into a single piece of glass transported, meeting the needs of deep processing. This eliminates a series of processes such as glass stacking, transfer, loading and unloading, reduces manual labor intensity, realizes the automation of the entire photovoltaic glass production line, improves the company's production efficiency, and reduces equipment investment costs.

[0004] Publication No. CN218931039U discloses a photovoltaic glass production line. The system employs a first conveying mechanism disposed on one side of a material unloading mechanism, and a second conveying mechanism disposed on a side of the first conveying mechanism away from the material unloading mechanism. An elevator is disposed on the second conveying mechanism. The first conveying mechanism conveys the photovoltaic glass produced by the glass sheet production line to the second conveying mechanism. The second conveying mechanism then conveys the photovoltaic glass to the elevator. Finally, the elevator transports the photovoltaic glass to a storage area. By providing the first and second conveying mechanisms to replace manual conveying, collisions between workers and the warehouse are reduced, conveying safety is improved, and production and transportation stability is enhanced.

[0005] Publication No. CN116395398A discloses an automatic sheet removal and stacking device for a photovoltaic glass production line. The device, with suction cups, can directly suck and remove the photovoltaic glass. Compared with negative pressure suction machines, it is less expensive to use. After suction, an air guide assembly allows outside air to enter the suction cups, facilitating separation of the photovoltaic glass from the suction cups and making unloading more convenient. Air can be simultaneously introduced into both suction cups by driving the air cylinder.

[0006] Publication No. CN215478314U discloses a buffering and storage device for an ultra-thin photovoltaic glass production line. The device is arranged between two sections of equipment. When the front section equipment fails, the hydraulic cylinder will intermittently drive the first, second, and third lifting plates to rise. The three lifting plates can buffer the photovoltaic glass delivered by the rear section equipment one by one, thus avoiding collision and squeezing with the photovoltaic glass on the front section equipment, thereby preventing damage to the photovoltaic glass, and having strong practicality. At the same time, when the equipment is operating normally, the first, second, and third lifting plates are reset and the buffered photovoltaic glass is transported one by one to the front section equipment via a roller conveyor belt. This allows the buffered photovoltaic glass to proceed to subsequent production processes, and has a good use effect.

[0007] The above-mentioned existing technologies cannot overcome the above-mentioned technical defects in the material connection and transfer between the cold end of the photovoltaic glass production line and the deep processing production line. Therefore, technical improvements are needed to solve the above-mentioned difficulties.

[0057] A method for connecting a cold end of a photovoltaic glass production line and a deep processing production line comprises the following steps:

[0059] Step 2: The materials temporarily stored in the film receiving device 1 are delivered to the shuttle conveyor 2 at one time. The materials received by the shuttle conveyor 2 are delivered to the film sending device 3 in left and right order.

[0060] Step 3: The sheet-sending device 3 delivers the materials one by one to the deep processing production line;

[0061] Step 4: Repeat steps 1 to 3, or repeat step 2.

[0062] The present application provides a connection system and method for the cold end of a photovoltaic glass production line and a deep processing production line, which has the following characteristics: as shown in FIG1 , taking the connection of a cold end production line and two deep processing production lines as an example, the sheet collecting device 1 collects the grouped glass sheets of the cold end production line in sequence, and after storing a certain number, delivers all the glass to the shuttle conveyor 2 located at station A at one time, and then the shuttle conveyor 2 moves to station A1, and the shuttle conveyor 2 divides all the glass into left and right sides and delivers them in sequence to the sheet sending device 3, and then the sheet sending device delivers them in sequence to the deep processing production line, and the above process is repeated to realize the connection between the cold end production line A and the deep processing production line A1; the shuttle conveyor 2 returns to station A, and the sheet collecting device 1 The grouped glass pieces of the cold end production line are collected again in sequence. After a certain number of pieces are stored, all the glass is transported to the shuttle conveyor 2 located at the A station at one time. Then the shuttle conveyor 2 moves to the A2 station. The shuttle conveyor 2 divides all the glass into left and right sides and transports them to the sheet sending device 3 in sequence. Then the sheet device transports them to the deep processing production line in sequence. Repeating the above process realizes the connection between the cold end production line A and the deep processing production line A2; repeating the above process completes the connection between one cold end production line and two deep processing production lines, and in the connection process, the two pieces of grouped glass transported side by side are automatically converted into single-piece glass, meeting the deep processing capacity requirements.

[0063] Specifically, taking the connection of two cold-end production lines and four deep-processing production lines as an example, as shown in Figure 8, the glass of the cold-end production line A is normally transported to the deep-processing production line A1 and the deep-processing production line A2 in sequence; the glass of the cold-end production line B is normally transported to the deep-processing production line B1 and the deep-processing production line B2 in sequence; when the glass of the cold-end production line needs to be quality inspected, the shuttle conveyor 2 of the cold-end production line will move to the AB station. At this time, the glass of the cold-end production line can be transported to the quality inspection and piece-picking device to complete the glass quality inspection. After the inspection is completed, it is transported back to the AB station of the shuttle conveyor 2, and then it can be transported to the deep-processing production line as needed.

[0064] Specifically, taking the connection of two cold-end production lines and four deep-processing production lines as an example, under normal circumstances, the two cold-end production lines operate independently, see Figure 8; under normal circumstances, the glass of cold-end production line A is transported to deep-processing production line A1 and deep-processing production line A2 in sequence; under normal circumstances, the glass of cold-end production line B is transported to deep-processing production line B1 and deep-processing production line B2 in sequence; when one of the cold-end production lines fails, the shuttle conveyor 2 of the cold-end production line will move to the AB station, and at this time, the glass of the cold-end production line can be transported to the loading and unloading device 6 to complete the loading and unloading of the glass, ensuring the efficient operation of the deep-processing production line; when the fault is resolved, the shuttle conveyor 2 of the cold-end production line will re-convey the glass transported from the cold-end production line to the corresponding deep-processing production line in sequence.

[0065] Specifically, taking the connection of two cold-end production lines and four deep-processing production lines as an example, the two cold-end production lines and the four deep-processing production lines are automatically connected. At the same time, the two cold-end production lines and the four deep-processing production lines can be interconnected. When the cold-end production line A fails, the glass of the cold-end production line B can be transported to the A1 deep-processing production line and the A2 deep-processing production line; the same applies vice versa; the two cold-end production lines and the four deep-processing production lines communicate data and share resources, which can achieve the most efficient glass production.

[0066] Specifically, the glass collecting device 1 at the end of the cold end production line, as shown in Figure 1, is used to receive the original glass sheets continuously produced by the cold end production line. The original glass sheets can be transported in pairs or as a whole piece of glass, which is called a group of glass. The device is composed of two or more vertically stacked rollers, as shown in Figure 2; each roller layer can receive a group of glass; the glass collecting device 1 can be raised or lowered in a step-by-step manner in the vertical direction, and the step distance is the same as the distance between each roller layer, so that each roller layer is connected to the main line roller in turn. Receive the glass delivered from the main line; each roller of the glass receiving device 1 is a single-drive belt conveyor A, which can simultaneously connect to the grouped glass delivered from the cold end production line, see Figure 5; the glass receiving device 1 consists of an active transmission shaft A13, a synchronous belt assembly A11, a synchronous belt assembly B14, a synchronous belt assembly C16, a synchronous belt assembly D101, a commutator A15, a commutator B102, a frame A17, and a single-drive belt conveyor A; the main motor A12 transmits power to the synchronous belt assembly A11, the synchronous belt assembly B14, the synchronous belt assembly C16, and the synchronous belt assembly D101 through the commutator, and the synchronous belt assembly A11, the synchronous belt assembly B14, the synchronous belt assembly C16, and the synchronous belt assembly D101 simultaneously tighten the frame of the multi-layer belt conveyor, so that the multi-layer single-drive belt conveyor A can be lifted and lowered at the same time according to the layer spacing.

[0067] Specifically, the shuttle conveyor 2, shown as part 1 in the attached figure, is located next to the sheet collecting device 1. The shuttle conveyor 2 is composed of two or more layers of rollers stacked vertically, as shown in the attached figure 3. The number of roller layers is the same as that of the sheet collecting device 1, and each layer of rollers can receive a group of glass. The glass from a cold end production line usually needs to be supplied to two deep processing production lines. Therefore, the shuttle conveyor 2 has three stations in the connection between the cold end production line A and the deep processing production line A1, and in the connection between the cold end production line A and the deep processing production line A2, namely station A, station A1, and station A2. The shuttle conveyor 2 can switch back and forth between the three stations, and transfer the glass transferred from the sheet collecting device 1 to the sheet sending device 3 in sequence.

[0068] Each roller conveyor on each layer of the glass receiving device 1 is a double-drive belt conveyor, which can first deliver the left glass to the glass sending device 3, and then deliver the right glass to the glass sending device 3, see Figure 6; the conveying process completes the conversion of glass from double-piece conveying to single-piece conveying; the shuttle conveyor device 2 consists of an active drive shaft B23, a synchronous belt assembly D101, a synchronous belt assembly E24, a synchronous belt assembly F26, a synchronous belt assembly G204, a commutator C25, a commutator D205, a frame B27, a single-drive belt conveyor B, a travel motor 201 and a travel wheel A29 , and walking wheel B203; the main motor B22 transmits power to the synchronous belt assembly D101, synchronous belt assembly E24, synchronous belt assembly F26, and synchronous belt assembly G204 through the commutator C25 and the commutator D205. The synchronous belt assembly D101, the synchronous belt assembly E24, the synchronous belt assembly F26, and the synchronous belt assembly G204 simultaneously tighten the frame of the multi-layer belt conveyor, so that the multi-layer single-drive belt conveyor B can be lifted and lowered according to the layer spacing at the same time; the walking motor 201 drives the walking wheel to move back and forth, so that the shuttle conveyor 2 can move at different stations.

[0069] Specifically, a glass sending device 3 is placed at the front end of the deep processing production line, as shown in part 1 in the accompanying drawings. The glass sending device 3 is composed of two or more vertically stacked rollers, as shown in Figure 4. The number of rollers is the same as that of the glass receiving device 1. Each roller layer can receive a group of glass. The glass sending device 3 can be raised or lowered in a step-by-step manner in the vertical direction. The step distance is the same as the distance between each roller layer, so that each roller layer is sequentially connected to the glass splicing roller, and the glass is sequentially sent to the roller of the deep processing production line.

[0070] Each roller conveyor on each layer of the glass launching device 3 is a single-drive belt conveyor, which can simultaneously dock the single-side glass delivered by the shuttle conveyor device 2, see Figure 7; the glass launching device 3 consists of an active transmission shaft C33, a synchronous belt assembly H31, a synchronous belt assembly I34, a synchronous belt assembly J36, a synchronous belt assembly K301, a commutator E35, a commutator F302, a frame C37, and a single-drive belt conveyor B; the main motor C32 transmits power to the synchronous belt assembly H31, the synchronous belt assembly I34, the synchronous belt assembly J36, and the synchronous belt assembly K301 through the commutator E35 and the commutator F302. The synchronous belt assembly H31, the synchronous belt assembly I34, the synchronous belt assembly J36, and the synchronous belt assembly K301 simultaneously tighten the frame of the multi-layer belt conveyor, so that the multi-layer single-drive belt conveyor B can be raised and lowered simultaneously according to the layer spacing.

[0071] In general, the technical solution of this application has the following characteristics:

[0072] Taking the glass conveying from cold end production line A to deep processing production line A1 and deep processing production line A2 as an example, this article explains how one deep processing production line is connected to two deep processing production lines. The glass conveying from cold end production line B to deep processing production line AB and deep processing production line B2 follows the same principle.

[0073] The glass collecting device 1 at the end of the cold end production line, see Figure 1, is used to receive the original glass sheets continuously produced by the cold end production line; the device is composed of more than two layers of rollers stacked vertically, see Figure 2; each layer of rollers can receive a group of glass; the glass collecting device 1 can be raised or lowered in a step-by-step manner in the vertical direction, with the step distance being the same as the distance between each layer of rollers, so that each layer of rollers can be docked with the main line rollers in turn to receive the glass conveyed by the main line; each layer of rollers in the glass collecting device 1 is a single-drive belt conveyor type, which can simultaneously dock with the group of glass conveyed from the cold end production line, see Figure 5; when each layer of rollers in the glass collecting device 1 is full of glass, the glass sending device 3 delivers all the stored glass to the shuttle conveyor device 2 at one time; after being emptied, the glass collecting device 1 collects the glass conveyed from the cold end production line again at one time;

[0074] The shuttle conveyor 2 is next to the glass collecting device 1, see item 1 in the attached figure; the shuttle conveyor 2 is composed of more than two layers of rollers stacked vertically, see attached figure 3, the number of roller layers is the same as that of the glass collecting device 1, and each layer of rollers can receive a group of glass; the glass of a cold end production line usually needs to be supplied to two deep processing production lines, so the shuttle conveyor 2 has three stations in completing the connection between the cold end production line A and the deep processing production line A1, and in completing the connection between the cold end production line A and the deep processing production line A2, namely the shuttle conveyor 2, station A, and the shuttle conveyor 2. Station A1 and shuttle conveyor 2, station A2, the shuttle conveyor 2 can switch back and forth between the three stations, and transfer the glass transferred from the glass receiving device 1 to the glass sending device 3 in sequence; each roller on the glass receiving device 1 is a double-drive belt conveyor, which can first butt-transfer the left glass to the glass sending device 3, and then butt-transfer the right glass to the glass sending device 3, see Figure 6, the conveying process completes the conversion of glass from double-piece conveying to single-piece conveying; the shuttle conveyor 2 transfers all the glass transferred from the glass receiving device 1 to the glass sending device 3 in sequence according to the left and right sides;

[0075] A glass ejection device 3 is placed at the front end of the deep processing production line, as shown in component 1 in the accompanying drawings. The glass ejection device 3 is composed of two or more vertically stacked roller conveyors (see Figure 4). The number of roller conveyor layers is the same as that of the glass receiving device 1. Each roller conveyor layer can receive a group of glass. The glass ejection device 3 can be raised or lowered in a step-by-step manner in the vertical direction. The step distance is the same as the distance between each roller conveyor layer, so that each roller conveyor layer is sequentially connected to the roller conveyor of the deep processing production line, and the glass is sequentially sent to the roller conveyor of the deep processing production line. Each roller conveyor layer of the glass ejection device 3 is a single-drive belt conveyor, which can simultaneously connect with a single side of glass delivered by the shuttle conveyor device 2. See Figure 7.

[0076] By repeating the above process, the double-sheet glass on the cold-end production line can be transformed into single sheets and transported to the corresponding deep-processing production line, thereby completing the automated connection between the photovoltaic glass cold-end production line and the deep-processing production line;

[0077] At the same time, under normal circumstances, the two cold-end production lines operate independently, as shown in Figure 8; the glass of the cold-end production line A is normally transported to the deep-processing production line A1 and the deep-processing production line A2 in sequence; the glass of the cold-end production line B is normally transported to the deep-processing production line B1 and the deep-processing production line B2 in sequence; when the glass of the cold-end production line needs to be quality inspected, the shuttle conveyor 2 of the cold-end production line will move to the shuttle conveyor 2, AB station, at which time the glass of the cold-end production line can be transported to the quality inspection and piece-picking device to complete the glass quality inspection. After the additional inspection is completed, the glass is transported back to the shuttle conveyor 2, AB station, and then can be transported to the deep-processing production line according to the needs;

[0078] At the same time, under normal circumstances, the two cold-end production lines operate independently, as shown in Figure 8; under normal circumstances, the glass of the cold-end production line A is transported to the deep-processing production line A1 and the deep-processing production line A2 in sequence; under normal circumstances, the glass of the cold-end production line B is transported to the deep-processing production line B1 and the deep-processing production line B2 in sequence; when one of the cold-end production lines fails, the shuttle conveyor 2 of the cold-end production line will move to the shuttle conveyor 2, AB station, at which time the glass of the cold-end production line can be transported to the upper and lower glass loading and unloading device 6 to complete the loading and unloading of the glass, ensuring the efficient operation of the deep-processing production line; when the failure is resolved, the shuttle conveyor 2 of the cold-end production line will re-transport the glass transported from the cold-end production line to the corresponding deep-processing production line in sequence;

[0079] Complete the automated connection of two cold-end production lines and four deep-processing production lines for photovoltaic glass. The automated connection is not limited to the number of cold-end production lines and deep-processing production lines; it is not limited to photovoltaic glass, and is also applicable to the transportation of other flat glass or plate-shaped items.

[0080] The double sheets or grouped glasses conveyed from the cold end production line are transformed into single sheets of glass and sequentially conveyed to the deep processing production line. The glass conveyed from the cold end production line is not limited to double sheets, but can also be single sheets or three or more sheets, which can also be transformed into single sheets and conveyed to the deep processing production line at once.

[0081] This application can realize the automated connection of two cold-end production lines and four deep-processing production lines. At the same time, the method is also equipped with a quality inspection and sheet picking process to facilitate the detection of glass quality. The quality of glass includes various properties related to glass quality, such as the size, shape, flatness, transmittance, thickness, residual stress, etc.

[0082] The present application can realize the automatic connection of two cold-end production lines and four deep-processing production lines. At the same time, the method also has loading and unloading stations. When the production capacity of one cold-end production line is greater than the production capacity of the corresponding deep-processing production line, the glass can be unloaded. Or when the production capacity of the cold-end production line does not meet the production capacity requirements of the deep-processing production line, the working efficiency of the deep-processing production line can be increased by loading the glass.

[0083] This application can realize the automatic connection of two cold-end production lines and four deep-processing production lines. At the same time, the two cold-end production lines and the four deep-processing production lines can be interconnected. When the cold-end production line A fails, the glass of the cold-end production line B can be transported to the A1 deep-processing production line and the A2 deep-processing production line; the same applies vice versa. The two cold-end production lines and the four deep-processing production lines can communicate data and share resources to achieve the most efficient glass production.

[0084] The movement of the shuttle conveyor 2 between various workstations is achieved by driving the traveling wheels on both sides to move on the guide rails 202 through the travel motor through the transmission shaft, and each shuttle conveyor 2 has two travel motors on the front and rear sides to drive the two traveling wheels respectively, and the travel motor and the transmission shaft are connected by a clutch; when one of the motors drives the traveling wheels through the transmission shaft, the other travel motor is in a disconnected state. At this time, two of the four traveling wheels are driving wheels, and the other two are following wheels; when one of the motors fails, the motor can be disconnected from the transmission shaft and the other travel motor is activated; therefore, the two travel motors are in a one-in-one and one-in-standby working condition, which increases the stability of the shuttle conveyor 2 equipment; the completion of the traveling action of the shuttle conveyor 2 is not limited to the traveling wheel method, and feasible traveling methods such as gears, belts, and chains are all within the protection scope of this solution;

[0085] The lifting mechanisms of the film receiving device 1, the shuttle conveying device 2 and the film sending device 3 can be realized by chain drive, gear drive, synchronous belt drive, etc.

[0086] The multi-layer roller conveyor in the glass receiving device 1, shuttle conveyor 2 and glass sending device 3 has more than 2 layers. The number of layers must be sufficient to ensure that the shuttle conveyor 2 has returned from other workstations and is in a waiting position before the glass receiving device 1 is full of glass. The glass can be transported by belt conveyor, roller, drum or other means.

[0087] The functions of the quality inspection and film retrieval station and the film loading and unloading station are not limited, and can also be other stations, such as glass storage stations or adding other production lines.

[0088] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
