Description

Technical Field

[0001] The utility model relates to the field of photovoltaic cell preparation, in particular to an integrated device for on-line adjustment of glue viscosity, a glue viscosity on-line adjustment system including the integrated device for on-line adjustment of glue viscosity, and a glue coating device including the integrated device for on-line adjustment of glue viscosity. Background Art

[0002] In the production process of some products, a glue coating process is involved. For example, in the preparation process of photovoltaic cells, the edges of the cells need to be evenly coated with glue, and a large amount of glue is wasted during the coating process. To save costs, the excess glue generated during the coating process needs to be recycled and reused after ensuring that the viscosity and performance meet the usage requirements. However, the glue has a certain viscosity and is extremely easy to cure, resulting in the blockage and failure of the entire pipeline system.

[0003] Patent 202322156128.4 discloses a glue coating system, but it only discloses the principle flow chart of glue recycling and does not disclose the specific structure of the equipment. On the other hand, the injection of glue from the glue injection container into the glue coating machine is controlled by an electromagnetic valve for on-off, and compressed air is used as the power for glue injection. There are disadvantages that the glue injection volume is uncontrollable, and the viscosity of the glue rises rapidly and is extremely easy to cure when it meets air. Using compressed air will accelerate the curing of the glue, resulting in frequent blockage of the electromagnetic valve and the need for cleaning. Summary of the Utility Model

Detailed implementation manners

[0028] In order to enable those in the technical field to better understand the technical solutions of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Such as Figures 1-4As shown in the figure, the integrated device 1 for on-line adjustment of glue viscosity in this embodiment includes a frame 2, a first space 31, a second space 32, and a third space 33 that are sequentially arranged on the frame 2. A stirring container 41 and a diluent container 42 are arranged in the first space 31, a glue supply container 43 is arranged in the second space 32, and a glue return container 44 is arranged in the third space 33. A pump body 6 is arranged below the first space 31, the second space 32, and the third space 33. The pump body 6 is used to provide the power for the colloid to flow between the containers. By arranging each container above the frame 2 and each pump body 6 below the frame 2, an integrated device is formed, with a high degree of space integration. Moreover, the pump body 6 is used as the driving force for colloid transportation between the containers, and the glue volume is controllable, avoiding the problems of glue curing and cleaning caused by the transportation method combining solenoid valves and compressed air.

[0030] In this embodiment, each of the stirring container 41, the diluent container 42, the glue supply container 43, and the glue return container 44 is provided with a high liquid level sensor 8 and a low liquid level sensor 8. The high liquid level sensor 8 corresponds to the upper limit of the liquid level in the container, and the low liquid level sensor 8 corresponds to the lower limit of the liquid level in the container. The liquid level state inside each container is monitored in real time to avoid too much or too little glue volume in the container.

[0031] The containers are connected through pipelines. The pump body 6 is arranged on the pipelines and is used to provide the driving force for the colloid to flow. The pipelines include a first pipeline 51, a second pipeline 52, a third pipeline 53, a fourth pipeline 54, and a fifth pipeline 55. The pump body 6 includes a first pump body 61, a second pump body 62, a third pump body 63, a fourth pump body 64, and a fifth pump body 65 arranged on the corresponding pipelines.

[0032] As Figure 4 shown, the connection relationship between the pipelines, the pump body 6, and the containers is specifically set as follows:

[0033] The glue supply container 43 is communicated with the glue coating device 10 through the first pipeline 51, and the first pump body 61 is arranged on the first pipeline 51. The glue supply container 43 stores the colloid within a predetermined viscosity range. The first pipeline 51, in cooperation with the first pump body 61, is used to transport the colloid within the predetermined viscosity range in the glue supply container 43 to the glue coating device 10 for use in glue coating by the glue coating device 10.

[0034] The glue coating device 10 is communicated with the glue return container 44 through the second pipeline 52 for recovering glue. The second pump body 62 is arranged on the second pipeline 52. During the glue coating process of the glue coating device 10, excess colloid is generated. The second pipeline 52, in cooperation with the second pump body 62, is used to recover the excess colloid generated during the glue coating process to the glue return container 44.

[0035] The glue return container 44 and the stirring container 41 are connected through a third pipeline 53. A third pump body 63 is arranged on the third pipeline 53. The third pipeline 53 and the third pump body 63 are used to transport the recycled colloid stored in the glue return container 44 to the stirring container 41.

[0036] The diluent container 42 and the stirring container 41 are connected through a fourth pipeline 54. A fourth pump body 64 is arranged on the fourth pipeline 54. Diluent is stored in the diluent container 42. The fourth pipeline 54 and the fourth pump body 64 are used to transport the diluent stored in the diluent container 42 to the stirring container 41 to be mixed with the glue in the stirring container 41 to make its viscosity reach the set value.

[0037] The stirring container 41 and the glue supply container 43 are connected through a fifth pipeline 55. A fifth pump body 65 is arranged on the fifth pipeline 55. The fifth pipeline 55 and the fifth pump body 65 are used to transport the qualified colloid stirred in the stirring container 41 to the glue supply container 43 for reuse.

[0038] Among them, the glue supply container 43, the first pipeline 51, the glue coating device 10, the second pipeline 52, the glue return container 44, the third pipeline 53, the stirring container 41, and the fifth pipeline 55 form a loop to realize the cycle of glue supply, recycling, glue mixing, and reuse.

[0039] One or more of the pump bodies 6 are metering pumps. Preferably, the first pump body 61 for supplying glue to the glue coating device 10 and the fourth pump body 64 for supplying diluent to the stirring container 41 are metering pumps, such as peristaltic pumps, gear pumps, plunger pumps, etc., to accurately control the delivery volume of the colloid or diluent. The number of the first pump bodies 61 is equipped with multiple groups according to the glue coating requirements, and multiple groups of the first pump bodies 61 can be arranged below the frame 2. The remaining other pump bodies 6 (the second pump body 62, the third pump body 63, and the fifth pump body 65) are ordinary pump bodies 6, such as pneumatic pumps, diaphragm pumps, etc.

[0040] A filtering device 12 is arranged at the pipeline opening of the glue return container 44 corresponding to the second pipeline 52, which is used to filter the excess colloid generated in the glue coating process transported by the second pipeline 52, filter out the sundries generated in the glue path circulation process, and then store them in the glue return container 44. An on-line viscometer 7 is arranged on the stirring container 41, which is used to detect the viscosity of the glue in the stirring container 41.

[0041] Discharge pipes 91 are arranged at the bottoms of the stirring container 41, the glue supply container 43, and the glue return container 44. Preferably, the discharge pipes 91 at the bottoms of the stirring container 41, the glue supply container 43, and the glue return container 44 are interconnected and have a discharge port 92. A valve body 11 is arranged on the discharge pipes 91 corresponding to the stirring container 41, the glue supply container 43, and the glue return container 44. The valve body 11 is arranged at the bottom of each container and is used to empty the colloid in the container to avoid the adverse effects caused by the solidification of the residual colloid.

[0042] The working process of the integrated device 1 for on-line adjustment of glue viscosity in this embodiment is briefly described as follows:

[0043] During glue coating production, first, initial glue with a predetermined viscosity is added to the glue supply container 43, and the added volume is between the high-level sensor 8 and the low-level sensor 8.

[0044] The first pump body 61 is started, and through the first pipeline 51 and the first pump body 61, the initial glue in the glue supply container 43 is transported to the glue coating device 10 for glue coating.

[0045] During the glue coating process, excess glue is generated, and through the second pipeline 52 and the second pump body 62, the excess glue is transported to the glue return container 44 for collection and storage.

[0046] When the volume of the recycled glue in the glue return container 44 reaches a predetermined value, such as the volume corresponding to the high-level sensor 8 in the glue return container 44, the third pump body 63 is started, and through the third pipeline 53 and the third pump body 63, the colloid in the glue return container 44 is transported to the stirring container 41. The on-line viscometer 7 on the stirring container 41 detects the viscosity of the colloid in the stirring container 41 and compares it with the standard value to determine whether the viscosity value of the colloid in the stirring container 41 is within the range required by the process. If the viscosity value of the colloid is within the required range, after direct stirring and standing, the fifth pump body 65 is started, and through the fifth pipeline 55 and the fifth pump body 65, the colloid is transported to the glue supply container 43 to realize the recycling of the colloid and ensure continuous production.

[0047] If the measured viscosity value of the colloid in the stirring container 41 exceeds the range required by the process, the fourth pump body 64 is started, and through the fourth pipeline 54 and the fourth pump body 64, the diluent in the diluent container 42 is quantitatively transported to the stirring container 41 and mixed and stirred with the colloid in the stirring container 41. Then, the viscosity of the colloid after stirring and adjustment is detected again. If the viscosity value of the colloid is within the required range at this time, after standing, the adjusted colloid is transported to the glue supply container 43 through the fifth pipeline 55 and the fifth pump body 65. If the viscosity value of the colloid still exceeds the range required by the process at this time, diluent is continuously added to the stirring container 41 quantitatively, and the above steps are repeated until the detected colloid viscosity is within the required range, and then it is transported to the glue supply container 43.

[0048] The integrated device for on-line adjustment of glue viscosity includes an alarm device. After the glue coating device 10 operates for a certain period of time and the glue amount is insufficient and the colloid in the glue supply container 43 is lower than the set minimum liquid level, the alarm device gives an alarm, and manual intervention is required to supplement the initial colloid.

[0049] When the glue application production ends or is suspended periodically, it is necessary to empty the residual glue inside the container. At this time, the valve body 11 at the bottom of the corresponding container is opened, or opened simultaneously, and the waste glue is discharged through the glue discharge pipe 91 and the glue discharge port 92 to avoid the solidification of the residual glue.

[0050] This embodiment also provides a glue viscosity online adjustment system including the glue viscosity online adjustment integrated device as described above. A metering pump is used as the power for injecting glue. The glue injection amount is controllable, there is no large amount of air in the glue bucket, which will not accelerate the solidification of the glue, and the metering pump will not be blocked by the glue. High and low liquid level sensors 8 are installed in each container to monitor the liquid level of the glue in the container. At the same time, when the viscosity of the recycled glue is too high, the viscosity of the glue can be adjusted by automatically adding a diluent to ensure the stability of the glue application production process.

[0051] This embodiment also provides a glue application device including the glue viscosity online adjustment integrated device as described above, which can be used to recycle glue online and in real time during the glue application process, effectively reducing glue waste and lowering production costs. The setting of the integrated device can facilitate moving and matching different glue application devices.

[0052] In summary, the present utility model provides a glue viscosity online adjustment integrated device, system and glue application device. The glue viscosity online adjustment integrated device includes a frame 2, a first space 31, a second space 32 and a third space 33 sequentially arranged on the frame 2. A stirring container 41 and a diluent container 42 are arranged in the first space 31, a glue supply container 43 is arranged in the second space 32, and a glue recycling container 44 is arranged in the third space 33. A pump body 6 is arranged below the first space 31, the second space 32 and the third space 33, and the pump body 6 is used to provide the power for the glue to flow between the containers. The glue supply container 43 is communicated with the glue application device for supplying glue to the glue application device. The glue application device is communicated with the glue recycling container 44 for recycling glue. The glue recycling container 44 is communicated with the stirring container 41 for transporting the recycled glue to the stirring container 41. The diluent container 42 is communicated with the stirring container 41 for injecting diluent into the stirring container 41. The stirring container 41 is communicated with the glue supply container 43. In the glue viscosity online adjustment integrated device of the present utility model, by integrating each container and the pump body in the frame to form an integrated device, the space integration degree is high, which is convenient for installation and maintenance. Moreover, a pump body is used as the driving force for transporting the glue between the containers, and the glue amount is controllable, avoiding the cleaning problem brought by the combination of the solenoid valve and the compressed air transportation method and reducing the maintenance cost.
