Description

[0002] At present, the drying tank of the photovoltaic trough equipment is basically welded by plates made of PVDF (polyvinylidene fluoride). Due to its weak heat preservation performance, especially after the cover of the drying tank is opened, during the process of the robotic arm grasping and placing the flower basket, the temperature inside the tank body of the drying tank drops significantly. After the temperature drops, the heating is slow, seriously affecting the drying effect of the drying tank, delaying and increasing the drying time, resulting in low efficiency of the drying tank and defective products.

[0045] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0046] Please refer to Figures 1 to 6 , in this embodiment, the drying device includes:

[0047] A tank body 110 and a cover plate 120. A cavity for placing the component 01 to be dried is provided inside the tank body 110, and the cover plate 120 is arranged on the opening side of the tank body 110;

[0048] A first pipeline 210 and a heat-insulating branch pipe 220 communicating with the first pipeline 210. The heat-insulating branch pipe 220 can be one or more. When the number of the heat-insulating branch pipes 220 is one, it can be arranged in a surrounding manner; the first pipeline 210 can be connected to the tank body 110. The heat-insulating branch pipe 220 is located on the side of the cavity close to the cover plate 120, and a nozzle 221 facing the cavity side is provided on the heat-insulating branch pipe 220; the nozzle 221 can jet air along the extending direction of the cover plate 120;

[0049] A second pipeline 310 and at least one group of drying branch pipes 320. The second pipeline 310 is connected to the tank body 110. For example, it can be connected to the middle of the tank body 110 for convenient arrangement. The drying branch pipes 320 are located inside the cavity and communicate with the second pipeline 310. A number of exhaust parts for hot air to flow into the cavity are provided on the drying branch pipes 320.

[0050] Specifically, the component 01 to be dried can be a flower basket and battery wafers, or other components that need to be dried; the first pipeline 210 and the second pipeline 310 adopt an up-and-down segmented design; the tank body 110 can be welded from PVDF material and can be in a cubic shape. An opening is provided on one side of the tank body 110, and the cover plate 120 is located on the opening side of the tank body 110, which is convenient for the robotic arm to pick and place the component 01 to be dried when the cover plate 120 is opened; the heat-insulating branch pipe 220 extends along the long side of the opening side of the tank body 110. Such an arrangement can ensure that the gas ejected by the nozzle 221 can cover the entire opening of the tank body 110; the nozzles 221 can be evenly arranged along the heat-insulating branch pipe 220 to ensure the uniformity of the blocking effect.

[0051] Furthermore, there can be multiple groups of drying branch pipes 320, which are arranged side by side inside the tank body 110. The number of each group of drying branch pipes 320 is 4 - 8, and they are distributed around the inside of the tank body 110, so that each drying branch pipe 320 of each group of drying branch pipes 320 is located around the component 01 to be dried, which is convenient for drying it; the exhaust parts on the drying branch pipes 320 can be structures such as exhaust holes or exhaust grooves, and any structure that can discharge gas is acceptable.

[0052] The drying device is provided with a second pipeline 310 and at least one set of drying branch pipes 320. The second pipeline 310 is located outside the tank body 110, and the drying branch pipes 320 are located inside the tank body 110. The second pipeline 310 can supply hot air to the drying branch pipes 320, and the drying branch pipes 320 transport the hot air into the cavity of the tank body 110. By using the heat and fluidity of the hot air, the components 01 to be dried are dried. At the same time, by setting a first pipeline 210 and several heat insulation branch pipes 220, the first pipeline 210 is located outside the tank body 110, and the heat insulation branch pipes 220 are located inside the tank body 110. The first pipeline 210 is used to transport hot air to the heat insulation branch pipes 220, and the heat insulation branch pipes 220 are used to blow the hot air into the cavity. Moreover, since the heat insulation branch pipes 220 are located on the side of the cavity close to the cover plate 120 and the heat insulation branch pipes 220 are provided with nozzles 221 that can jet air along the extension direction of the cover plate 120, when the cover plate 120 is opened, through the action of the heat insulation branch pipes 220 and the nozzles 221, a barrier can be formed at the opening of the tank body 110, effectively preventing the cold air outside the tank body 110 from entering the tank body 110 and at the same time preventing the hot air inside the tank body 110 from flowing out, achieving the effects of blocking air and heat preservation, avoiding the temperature inside the tank body 110 from dropping too fast, improving the drying efficiency, reducing energy consumption and saving costs.

[0053] In some embodiments, the number of the heat insulation branch pipes 220 is at least two, and at least one heat insulation branch pipe 220 is arranged on each side of the tank body 110. The nozzle 221 is arranged on the side of the heat insulation branch pipe 220 close to the cavity. Specifically, by arranging heat insulation branch pipes 220 on the opposite sides of the opening side of the tank body 110 and the nozzles 221 are arranged oppositely, it can ensure that the gas ejected by the nozzles 221 more completely covers the opening of the tank body 110. After the cover plate 120 is opened, the temperature drop inside the tank body 110 is reduced and delayed, and the rapid temperature drop inside the tank body 110 is avoided.

[0054] In some embodiments, the nozzles 221 on the heat insulation branch pipes 220 located on both sides of the tank body 110 are arranged in a staggered manner. By arranging the nozzles 221 on the two heat insulation branch pipes 220 in a staggered manner, it is to avoid forming a gap between adjacent nozzles 221 on the same heat insulation branch pipe 220, so as to prevent the gas inside and outside the tank body 110 from entering and leaving through the gap, and the blocking effect can be further improved.

[0055] In some embodiments, as Figure 3 shown, the cavity includes a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 are arranged along the depth direction of the tank body 110. The first cavity 111 is close to the cover plate 120, and the heat insulation branch pipes 220 are located in the first cavity 111 for blocking air. The drying branch pipes 320 are located in the second cavity 112 for performing the drying process.

[0056] In some embodiments, asFigure 5 As shown, a limiting member 113 is provided on the side wall of the first cavity 111. The drying branch pipe 320 is placed within the limiting member 113. The limiting member 113 is L-shaped and fixed to the inner wall of the tank body 110. A groove is formed between the limiting member 113 and the inner wall of the tank body 110. The drying branch pipe 320 is placed into the groove. The size of the limiting member 113 is adapted to the size of the drying branch pipe 320, ensuring that the drying branch pipe 320 is convenient to install and does not shake.

[0057] In some embodiments, a plurality of air extraction branch pipes 400 are further provided at the bottom of the tank body 110. An air extraction pneumatic valve 410 is provided on each air extraction branch pipe 400. The air extraction pneumatic valve 410 is used to control the opening or closing of the air extraction branch pipe 400, thereby realizing the discharge of the gas in the tank body 110.

[0058] In some embodiments, there are at least two groups of drying branch pipes 320. The number of cover plates 120 is at least two, and the cover plates 120, each group of drying branch pipes 320, and the air extraction branch pipes 400 correspond one by one. Multiple groups of drying branch pipes 320 can be provided within a single tank body 110. Each group of drying branch pipes 320 corresponds to a cover plate 120 and an air extraction branch pipe 400. During actual use, the corresponding drying branch pipes 320 and air extraction branch pipes 400 can be selected and opened according to the placement position of the component 01 to be dried, saving costs.

[0059] In some embodiments, a main pipeline 500 is further included. The first pipeline 210 and the second pipeline 310 are both connected to the main pipeline 500. A first intake air pneumatic valve 211 for opening or closing the first pipeline 210 is provided on the first pipeline 210. A second intake air pneumatic valve 311 for opening or closing the second pipeline 310 is provided on the second pipeline 310. Further, a controller is included. The controller is connected to the first intake air pneumatic valve 211 and the second intake air pneumatic valve 311 and is used to control the opening and closing of the first intake air pneumatic valve 211 and the second intake air pneumatic valve 311, thereby cooperating with the opening or closing of the cover plate 120.

[0060] Specifically, in a specific embodiment, the cover plate 120 at least includes a first cover plate 121 and a second cover plate 122. The extending directions of the first cover plate 121 and the second cover plate 122 are parallel to the extending directions of the drying branch pipe 320 and the heat insulation branch pipe 220. The first cover plate 121 and the second cover plate 122 are arranged along the width direction of the tank body 110; the air extraction branch pipe 400 includes a first air extraction branch pipe 400 and a second air extraction branch pipe 400. A first air extraction pneumatic valve is provided on the first air extraction branch pipe 400, and a second air extraction pneumatic valve is provided on the second air extraction branch pipe 400; the drying branch pipe 320 includes a first group of drying branch pipes 320 and a second group of drying branch pipes 320. The first cover plate 121, the first group of drying branch pipes 320 and the first air extraction branch pipe 400 are arranged in sequence, and the second cover plate 122, the second group of drying branch pipes 320 and the second air extraction branch pipe 400 are arranged in sequence. Of course, a third cover plate 120, a third group of drying branch pipes 320 and a third air extraction branch pipe 400 can also be provided, which can be set according to actual needs. In this article, an example is introduced with two cover plates 120, two groups of drying branch pipes 320, and two air extraction branch pipes 400.

[0061] When there is no component 01 to be dried inside the tank body 110, the first cover plate 121 and the second cover plate 122 on the left and right sides of the tank body 110 are in a closed state, the second air inlet pneumatic valve 311, the first air extraction pneumatic valve and the second air extraction pneumatic valve are opened. After the hot air in the main pipeline 500 passes through the second pipeline 310, it passes through the second cavity 112 of the tank body 110 and then converges into each drying branch pipe 320. The number of partition branch pipes can be 4 - 8. At that time, the temperature inside the tank body 110 will rise. At the same time, the mixed air volume inside the tank body 110 will be taken away through the first air extraction branch pipe 400 and the second air extraction branch pipe 400 at the bottom of the tank body 110 and then circulated and heated to keep the temperature of the tank body 110 rising stably.

[0062] When the tank body 110 reaches the process temperature, it will send out a feeding requirement. Before feeding, the first intake pneumatic valve 211 will be opened first, and then the second intake pneumatic valve 311, the first exhaust pneumatic valve and the second exhaust pneumatic valve will be closed. At this time, hot air will enter the first cavity 111 from the first pipeline 210, then converge into the heat insulation branch pipe 220, and horizontally shoot out from the nozzle 221 of the heat insulation branch pipe 220, forming a gas isolation layer above the tank body 110, making the inside and outside of the tank body 110 form two regions, keeping the temperature inside the tank body 110 from losing, and at the same time blocking the air flow outside the tank body 110 from entering the inside of the tank body 110. At this time, the first cover plate 121 and the second cover plate 122 of the tank body 110 are opened, and the robotic arm places the components 01 to be dried. For example, there can be four, and two components 01 to be dried are placed on each group of drying branch pipes 320. After the placement is completed, the first cover plate 121 and the second cover plate 122 are closed. Then, the second intake pneumatic valve 311, the first exhaust pneumatic valve and the second exhaust pneumatic valve will be opened first for heating up, and then the first intake pneumatic valve 211 will be closed to keep the heat energy of the tank body 110 from losing and effectively raise the temperature inside the tank body 110 to perform the drying process.

[0063] When the drying process inside the tank body 110 is completed, the first intake pneumatic valve 211 will be opened first again, then the second intake pneumatic valve 311, the first exhaust pneumatic valve and the second exhaust pneumatic valve will be closed, and then the first cover plate 121 and the second cover plate 122 will be opened to keep a gas isolation layer between the inside and outside of the tank body 110, so that the temperature inside the tank body 110 will not drop due to the peripheral operating state. After the robotic arm grabs the components 01 to be dried, repeat the above steps to cause reciprocating cyclic operation.

[0064] In some embodiments, please refer to Figures 7 to 10 , to further improve the drying efficiency, there are multiple tank bodies 110, and each tank body 110 is connected with a first pipeline 210 and a second pipeline 310.

[0065] Furthermore, it further includes a heater 610, a first fan 620 and a second fan 630. The first fan 620, the heater 610, the second fan 630 and the tank body 110 are sequentially connected by pipelines, that is, the gas in the second fan 630 enters each tank body 110 in turn, then converges into the first fan 620, and then flows back to the second fan 630 after passing through the heater 610, so as to circulate like this; the number of tank bodies 110 is multiple, and a regulating valve 510 is provided on the total pipeline 500 of each tank body 110 to regulate the air flow rate entering the cavity of each tank body 110. Specifically, the tank body 110 is provided with an exhaust branch pipe 400, and the exhaust branch pipe 400 is communicated with the first fan 620.

[0066] In some embodiments, as Figure 9 shown, a first intake pipe 640 is provided between the first fan 620 and the heater 610, and a second intake pipe 650 and a third intake pipe 660 are provided between the first fan 620 and the main pipeline 500.

One end of the second intake pipe 650 is connected to the first fan 620, and the other end is connected to the middle of the third intake pipe 660. The main pipeline 500 of each tank body 110 is sequentially connected to the third intake pipe 660; specifically, the heater 610 is located between the first fan 620 and the second fan 630. Through the above arrangement, the occupied space of the device can be minimized.

[0072] When the first tank body and the second tank body are in the drying process and the third tank body starts the drying process, the air intake of the first regulating valve drops to 20% of the total air volume, the air intake of the second regulating valve drops to 30% of the total air volume, and the air intake of the third regulating valve is controlled to increase to 40% of the total air volume; the fourth tank body remains in the standby state, and the air intake of the fourth regulating valve is controlled to account for 10% of the total air volume.

[0073] When the fourth tank body starts the drying process, at this time, the component 01 to be dried in the first tank body is taken out after the process is completed, and the first tank body enters the standby state. The air intake of the first regulating valve is controlled to drop to 10% of the total air volume; the second tank body is in the drying process, and the air intake of the second regulating valve is controlled to drop to 20% of the total air volume; the third tank body is in the drying process, and the air intake of the third regulating valve is controlled to drop to 30% of the total air volume; the air intake of the fourth regulating valve is controlled to increase to 40% of the total air volume.

[0074] Through the above settings, by setting multiple tank bodies 110 and cooperating with the heater 610 and two fans, the existing heating control operation mode is changed structurally, which can realize automatic control and energy conservation. Through adding a circulation pipeline and an electric angle regulating valve 510 to achieve the above overall control, according to the sequence rhythm of the components 01 to be dried entering the tank body 110, the air intake and hot air circulation of each tank body 110 are adjusted in turn to achieve the purpose of precise control. In summary, cycling in turn, the drying time is between 600 - 700 seconds. Generally, 4 states are divided according to the above states, and the corresponding drying times are also equal. The tank body 110 is filled with fast heat, and when the process temperature state is reached, the air intake is appropriately decreased. Correspondingly, the air intake of all tank bodies 110 can be controlled, reducing the state of the original single-tank independent process and realizing centralized distribution control. When the output is not high, other tank bodies 110 remain in the standby state or can be closed, so that the energy consumption loss of the heater 610 can be reduced, and the existing output process can be completed with a small amount of energy consumption. When the output increases, the temperature can also be quickly increased to maintain the process state and enter production at any time.

[0075] In some embodiments, the first fan 620, the second fan 630, and the heater 610 are arranged outside the main machine platform, avoiding the influence of the heat generated by the continuous operation of the fan on the operation of the main machine platform and ensuring the safe and stable operation of the main machine platform; the gas is transmitted over a long distance through the second air inlet pipe 650 and the second exhaust main pipe 680.

[0076] In a specific embodiment, the drying of the tank body 110 relies on the combined operation of the first fan 620, the second fan 630 and the heater 610, continuously circulating hot air inside the tank body 110 to achieve the purpose of hot air drying. Since it is an integrated hot air control and distribution system, the opening and closing angle of the electric angle regulating valve 510 will be adjusted sequentially according to the production sequence rhythm to automatically control the air intake volume of the tank body 110 and achieve the purpose of precise drying. The adjustment angles of the electric angle regulating valve 510 are set to four working modes of 40%, 30%, 20%, and 10% of the total air volume respectively, corresponding to the drying state inside the tank body 110. Of course, the proportion of the air intake volume of each regulating valve 510 in the total air volume can also be adjusted as needed, not limited to the proportions given in this embodiment.

[0077] The specific operation is as follows: After the main equipment is started, the first fan 620 and the second fan 630 keep working. The first fan 620 passes the internal air flow of the tank body 110 through the main pipeline 500 of each tank body 110, and then through the first pipeline 210 and the second pipeline 310 of each tank body 110, enters the tank body 110, and then enters the second exhaust main pipe 680 through the exhaust branch pipe 400 of each tank body 110, flows back to the first fan 620, and enters the first exhaust main pipe 670 after being compressed by the first fan 620. At this time, the compressed air will enter the heater 610 to be heated, and the output reaches the process temperature, between 140°C and 160°C. The output hot air reaches the first intake pipe 640, is pressurized by the second fan 630 and transported to the second intake pipe 650, and then injected into the third intake pipe 660 and respectively corresponds to the main pipeline 500 of each tank body 110. The main pipeline 500 of each tank body 110 is provided with an electric angle regulating valve 510, and then four opening and closing angle states are adjusted according to the process conditions;

[0078] When the drying process of the first tank body is carried out, the first regulating valve will inject 40% of the total air volume into the first cavity 111 and the second cavity 112 of the first tank body through the first intake pneumatic valve 211 and the second intake pneumatic valve 311 of the first tank body respectively and enter the interior of the first tank body to rapidly increase the temperature. When it reaches 1 / 3 of the total process time, the first regulating valve will reduce the air volume of 40% of the total air volume to 30% of the air volume. At this time, the first intake pneumatic valve 211 of the first tank body will close, and the hot air can only enter the second cavity 112 through the second intake pneumatic valve 311 of the first tank body and heat the interior of the first tank body. When it reaches 2 / 3 of the total process time, the first regulating valve will reduce the air volume of 30% of the total air volume to 20% and transport it to the interior of the first tank body. It still enters the second cavity 112 through the second intake pneumatic valve 311 and heats the interior of the first tank body. During the whole process, the second intake pneumatic valve 311 of the first tank body remains open, and a complete set of circulation will be formed inside the first tank body. The hot air enters the second exhaust main pipe through the exhaust pipe branch at the bottom of the first tank body for sequential circulation heating, fully maintaining the drying circulation effect of the first tank body and meeting the process requirements. When the process time is completed, the first regulating valve reduces the air volume of 20% of the total air volume to 10%. At the same time, the exhaust pneumatic valve of the first tank body is closed. After closing the circulation of the first tank body, the hot air enters the second cavity 112 through the second intake pneumatic valve 311 to keep the interior of the first tank body at a controlled temperature, so that the temperature inside the first tank body can be maintained without decreasing. The above is a process cycle, and the process operations of multiple corresponding tank bodies 110 are also in this mode, achieving the function of integrated drying and maintaining hot air control to ensure safe and effective operation.

[0079] This drying device can reduce the temperature loss caused by the opening of the cover plate 120; the slow decrease in the temperature of the tank body 110 results in a shorter heating-up time and can quickly reach the process temperature; the shortening of the heating time can reduce the heating energy consumption; reducing the heating time can improve the equipment production capacity, and can avoid the problems of equipment production cost caused by the increase of the tank body 110 and the insufficient utilization rate of the workshop site.
