[0046] Embodiment 1:

[0047] In the prior art, the transfer mechanism adopts a conveyor belt form, which can only transport the workpiece to be cured in the horizontal direction. Therefore, the preheating chamber 11, the curing chamber 12 and the cooling chamber 13 can only be arranged in a horizontal straight line. The waste heat after curing in the curing chamber 12 is generally discharged directly to the outside, or a pipeline is set between the curing chamber 12 and the preheating chamber 11 for communication, and then a fan is set to provide driving force to transport the waste heat in the curing chamber 12 to the preheating chamber 11 through the pipeline. The waste heat loss in the pipeline is relatively large, and the utilization rate of the waste heat is relatively low.

[0048] To solve the above problems, as shown in Figures 1 and 2, the embodiment of the present application provides a photovoltaic curing device for curing a workpiece 5 to be cured. The present application mainly relates to the improvement of the photovoltaic curing device, and does not limit the workpiece 5 to be processed by the photovoltaic curing device.

[0049] Specifically, the photovoltaic curing device includes a preheating chamber 11, a curing chamber 12, and a cooling chamber 13 arranged along a first direction. The preheating chamber 11 and the curing chamber 12 are interconnected, and the airflow in the curing chamber 12 can naturally rise and flow into the preheating chamber 11. The curing chamber 12 is interconnected with the cooling chamber 13. In some embodiments, the first direction is the up-down direction shown in 1, the preheating chamber 11 is directly above the curing chamber 12, and the airflow in the curing chamber 12 directly enters the preheating chamber 11 when it rises vertically upward; in some other embodiments, the first direction is an inclined upward direction, the preheating chamber 11 is obliquely above the curing chamber 12, and the airflow in the curing chamber 12 can also enter the preheating chamber 11 when it rises upward in a natural state.

[0050] By arranging the preheating chamber 11, the curing chamber 12 and the cooling chamber 13 along the first direction, and arranging the preheating chamber 11 and the curing chamber 12 to be fluidically connected, the heat generated during the curing operation in the curing chamber 12 can naturally rise and flow into the preheating chamber 11 to preheat the workpiece 5, thereby improving the utilization rate of the waste heat after curing in the curing chamber 12, which is beneficial to saving the energy consumption for preheating. Moreover, by making full use of the principle that waste heat naturally moves in the direction of movement, there is no need to set up an additional conveying device to convey the waste heat to the preheating chamber 11. Compared with the technical solution in the prior art that the preheating chamber 11, the curing chamber 12 and the cooling chamber 13 are arranged horizontally and an additional conveying device is set up to transfer waste heat between the curing chamber 12 and the preheating chamber 11, the overall structure of the photovoltaic curing equipment is simplified. When the first direction is a vertical direction, the vertical arrangement of the preheating chamber 11, the curing chamber 12 and the cooling chamber 13 can make full use of the height space of the workshop, shorten the length of the production line, and is beneficial to improving the utilization rate of the unit workshop area.

[0051] In one embodiment, the preheating chamber 11 and the curing chamber 12 are connected, and no partition or other blocking structure is provided therebetween, so that the waste heat in the curing chamber 12 can quickly enter the preheating chamber 11 .

[0052] In one embodiment, the side wall of the preheating chamber 11 and the side wall of the curing chamber 12 are connected to form a first channel defined by the side wall of the preheating chamber 11 and the side wall of the curing chamber 12; the airflow in the curing chamber 12 naturally rises through the first channel and flows into the preheating chamber 11. By directly connecting the curing chamber 12 and the preheating chamber 11, the waste heat in the curing chamber 12 can directly enter the preheating chamber 11 without passing through other connecting pipes.

[0053] In one embodiment, the side walls of the curing cavity 12 and the cooling cavity 13 are connected to form a second channel defined by the side walls of the curing cavity 12 and the cooling cavity 13. Moreover, the preheating cavity 11 is connected with the curing cavity 12 to form a first channel, and the workpiece 5 reciprocates between the preheating cavity 11, the curing cavity 12 and the cooling cavity 13 through the first channel and the second channel, so that preheating, curing and cooling operations can be realized in sequence.

[0054] In one embodiment, the preheating cavity 11, the curing cavity 12 and the cooling cavity 13 are an integrated structure to form the working cavity 1. In the direction perpendicular to the first direction, the preheating cavity 11, the curing cavity 12 and the cooling cavity 13 have the same size. The preheating cavity 11, the curing cavity 12 and the cooling cavity 13 form a through state. The upper part of the working cavity 1 is the preheating cavity 11, the middle part is the curing cavity 12, and the bottom is the cooling cavity 13. The transfer channel of the workpiece 5 in the working cavity 1 is relatively smooth, and the integrated structure processing is also faster.

[0055] In one embodiment, as shown in FIG1 , a feed port 111 is provided on the cavity wall of the preheating cavity 11, and a discharge port 131 is provided on the cavity wall of the cooling cavity 13. The workpiece 5 enters the preheating cavity 11 from the feed port 111, moves downward to the curing cavity 12 for curing after preheating, continues to move downward to the cooling cavity 13 for cooling after curing, and moves out from the discharge port 131 after cooling.

[0056] At the beginning of curing, waste heat has not been generated in the curing cavity 12 or the temperature of the waste heat alone cannot make the temperature in the preheating cavity 11 reach the preheating requirement. Therefore, a second heater is provided in the preheating cavity 11, and the second heater is used to heat the preheating cavity 11. When the temperature in the preheating cavity 11 is lower than the required preheating temperature, the second heater is started to heat the preheating cavity 11. When the waste heat transmitted by the curing cavity 12 in the preheating cavity 11 can reach the required preheating temperature, the second heater is turned off. Specifically, the second heater can be a heating wire, and the heating wire is attached to the inner wall of the preheating cavity 11.

[0057] Optionally, a first temperature sensor is provided in the preheating cavity 11, and the first temperature sensor is used to detect the temperature in the preheating cavity 11. When the first temperature sensor detects that the temperature in the preheating cavity 11 is lower than the required preheating temperature, the second heater is started for heating; when the first temperature sensor detects that the temperature in the preheating cavity 11 is higher than the required preheating temperature, the preheating cavity 11 needs to be cooled.

[0058] As shown in FIG1 , in order to adjust the temperature of the preheating cavity 11, a heat dissipation port 112 is also provided on the cavity wall of the preheating cavity 11, and a movable baffle or shutter is provided at the heat dissipation port 112. By pushing and pulling the movable baffle or adjusting the angle of the shutter, the ventilation volume of the heat dissipation port 112 can be adjusted. When the temperature in the preheating cavity 11 is too high, the ventilation volume of the heat dissipation port 112 is increased to quickly dissipate the heat in the preheating cavity 11, thereby achieving the purpose of lowering the temperature in the preheating cavity 11; when the temperature in the preheating cavity 11 is too low, the ventilation volume of the heat dissipation port 112 is reduced or the heat dissipation port 112 is closed, so that the temperature in the preheating cavity 11 can be quickly restored.

[0059] Please continue to refer to Figure 1. In order to realize the up and down movement of the workpiece 5 in the working chamber 1, the photovoltaic curing equipment also includes a transfer mechanism 2. The transfer mechanism 2 is used to carry the workpiece 5 to be cured, and drive the workpiece 5 to move back and forth between the preheating chamber 11, the curing chamber 12 and the cooling chamber 13 through the first channel and the second channel, so as to make the preheating, curing and cooling operation processes of the workpiece 5 continuous, which is conducive to improving the operation efficiency.

[0060] Specifically, the transfer mechanism 2 includes a carrier 21 and a transfer drive. The carrier 21 is used to carry the workpiece 5 . The transfer drive is used to drive the carrier 21 to reciprocate along a first direction to transport the workpiece 5 .

[0061] In one embodiment, the transfer mechanism 2 also includes a guide column 22, which is extended along a first direction in the preheating chamber 11, the curing chamber 12 and the cooling chamber 13, and the carrier 21 is slidably set on the guide column 22, and the transfer drive member is used to drive the carrier 21 to slide along the guide column 22.

[0062] There are two guide posts 22, which are respectively arranged on opposite sides of the carrier 21 to provide better guidance for the sliding of the carrier 21. The transfer drive member can be a cylinder, an electric cylinder or a motor screw module, etc., which can drive the carrier 21 to move linearly, and its specific structural form is not limited here.

[0063] Optionally, as shown in Fig. 3, connecting ears 212 are respectively provided on opposite sides of the carrier 21, and connecting holes are provided on the connecting ears 212, and the guide column 22 is slidably inserted into the connecting holes. By arranging the connecting ears 212 to be slidably connected with the guide column 22, the guide column 22 can avoid the bearing surface of the carrier 21, thereby facilitating the loading and unloading of the workpiece 5 on the carrier 21.

[0064] In order to improve the curing effect, a first heater is provided on the carrier 21, and the first heater is used to heat the workpiece 5. The heating temperature is generally controlled at 70°C-90°C. The first heater can be a heating wire, a water-cooling plate or a water bath. When a heating wire or a water-cooling plate is used, the heating wire or the water-cooling plate can be directly embedded in the upper surface of the carrier 21, so that the heating wire or the water-cooling plate contacts the workpiece 5 and heats the back of the workpiece 5.

[0065] Optionally, a second temperature sensor is provided on the carrier 21, and the second temperature sensor is used to detect the upper surface temperature of the carrier 21 in real time. When the detected temperature is lower than the set temperature, the input power of the first heater is increased to increase the heating temperature; when the detected temperature is higher than the set temperature, the input power of the first heater is reduced to lower the heating temperature.

[0066] In this embodiment, the workpiece 5 is heated in a water bath. To achieve this purpose, the carrier 21 is set as a carrier plate, and the carrier plate can contain liquid, which can heat the workpiece 5. The liquid level is 3mm-5mm higher than the upper surface of the workpiece 5 to ensure uniform heating of the workpiece 5.

[0067] Optionally, a heating wire is provided on the upper surface of the carrier plate, and the liquid in the carrier plate is heated by the heating wire to keep the liquid at an optimal temperature.

[0068] Please refer back to Figure 1. The photovoltaic curing equipment also includes a light source module 4. The light source module 4 is arranged in the curing chamber 12. The light source module 4 includes a curing lamp 41 and a movable driving member. An inlet and outlet 121 is arranged on the cavity wall of the curing chamber 12. The movable driving member can drive the curing lamp 41 to enter the curing chamber 12 through the inlet and outlet 121 or move out of the curing chamber 12 from the inlet and outlet 121. In the process of the carrier 21 moving up and down, the movable driving member drives the curing lamp 41 to move out of the curing chamber 12 from the inlet and outlet 121 to prevent the curing lamp 41 from blocking the movement of the carrier 21. When the carrier 21 carries the workpiece 5 to the position below the inlet and outlet 121, the curing lamp 41 is moved to the position above the workpiece 5 in the curing chamber 12 to start curing the workpiece 5. Optionally, when the curing lamp 41 is working, it maintains a distance of 3cm-5cm from the upper surface of the workpiece 5.

[0069] In some embodiments, the mobile driving member adopts a cylinder or an electric cylinder, the fixed end of the cylinder or the electric cylinder is connected to the outer wall of the working chamber 1, and the curing light 41 is connected to the driving end of the cylinder or the electric cylinder through two connecting rods 42. The cylinder or the electric cylinder drives the connecting rod 42 to move linearly to drive the curing light 41 in and out of the curing chamber 12.

[0070] It is understandable that in some other embodiments, the mobile driving member may also adopt a motor screw module that can drive the curing lamp 41 to move back and forth in a straight line, and the specific structural form of the mobile driving member is not limited herein.

[0071] After the workpiece 5 is cooled, a mechanical claw is used to extend from the discharge port 131 into the cooling cavity 13 to clamp the workpiece 5 out. Since the workpiece 5 is usually a thin sheet and is attached to the upper surface of the carrier 21, it is not convenient to clamp it directly. To this end, in combination with Figures 1 and 4, the photovoltaic curing equipment also includes an ejection device 3, which is arranged in the cooling cavity 13. The ejection device 3 includes a plurality of ejector rods 31. The carrier 21 is provided with a plurality of sockets 211 corresponding to the ejector rods 31. The ejector rods 31 can pass through the sockets 211 to push the workpiece 5 on the carrier 21 away from the carrier 21. The workpiece 5 leaves the upper surface of the carrier 21, which is convenient for the mechanical claw to clamp the workpiece 5.

[0072] In one embodiment, four push rods 31 are provided. The four push rods 31 are distributed in a square shape and can respectively abut against four corners of the workpiece 5 to lift the workpiece 5 stably.

[0073] Optionally, the push rod 31 is made of stainless steel, aluminum or quartz, and the top of the push rod 31 is set as an arc surface to prevent the push rod 31 from damaging the workpiece 5. Further, the top of the push rod 31 is coated with silica gel or sponge to better protect the workpiece 5.

[0074] In order to facilitate the installation of the ejector rod 31, as shown in Figure 1, the ejector device 3 also includes a base 32, which is arranged on the bottom plate of the working chamber 1, and the ejector rod 31 is arranged on the base 32. Specifically, the base 32 is arranged as a square structure, and the four ejector rods 31 are respectively arranged at the four corners of the upper surface of the base 32.

[0075] When the workpiece 5 is heated in a water bath, the carrier 21 contains liquid. In order to prevent the liquid from leaking from the insertion hole 211, a rubber sealing plug is provided in the insertion hole 211. The rubber sealing plug is provided with a self-sealing hole. The push rod 31 can pass through the self-sealing hole and extend to the upper surface of the carrier 21 to lift the workpiece 5. When the push rod 31 is pulled out of the self-sealing hole, the self-sealing hole can be automatically sealed, and the liquid cannot leak from the sealing hole.

[0076] In the cooling cavity 13, the workpiece 5 needs to be cooled down quickly. At this time, the liquid used in the water bath will affect the cooling speed. For this reason, after the workpiece 5 is transported to the cooling cavity 13, it is considered to discharge the liquid in the carrier plate. In this embodiment, the water in the carrier plate is discharged into the base 32 by designing the base 32 and the push rod 31. Specifically, as shown in Figures 1 and 5, a liquid storage cavity is provided in the base 32, a liquid discharge channel is provided in the push rod 31, and the liquid discharge channel is connected to the liquid storage cavity. A through hole 311 is provided at the upper end of the push rod 31, and the through hole 311 is connected to the liquid discharge channel. When the push rod 31 is extended into the carrier plate, the liquid in the carrier plate can flow into the liquid storage cavity through the through hole 311 and the liquid discharge channel to prevent the high-temperature liquid in the carrier plate from affecting the rapid cooling of the workpiece 5.

[0077] Optionally, two through holes 311 are provided along the upper and lower extension directions of the push rod 31, wherein when the push rod 31 is inserted into the insertion hole 211, the upper side of the lower through hole 311 is higher than the bottom of the supporting plate, while the lower side of the lower through hole 311 is not higher than the bottom of the supporting plate, so that all the liquid in the supporting plate can flow out through the lower through hole 311.

[0078] Furthermore, a water return pipe is provided between the liquid storage cavity of the base 32 and the carrier plate, and a water pump is provided on the water return pipe, and the water pump can pump the liquid in the liquid storage cavity back to the carrier plate. When the workpiece 5 is cooled and taken away by the manipulator, the liquid in the liquid storage cavity is pumped back to the carrier plate, and then the carrier plate continues to move up to the preheating cavity 11 to receive the next workpiece 5.

[0079] Furthermore, in order to accelerate the cooling of the workpiece 5, a fan is also provided in the cooling chamber 13, and the fan cools down the solidified workpiece 5. Furthermore, the fan can also accelerate the upward movement of the heat emitted by the workpiece 5, so that the heat quickly reaches the preheating chamber 11.

[0080] Embodiment 2:

[0081] As shown in FIG. 6 and FIG. 7 , the embodiment of the present application further improves the photovoltaic curing equipment based on the first embodiment.

[0082] In order to improve the working efficiency of the photovoltaic curing equipment, at least two groups of transfer mechanisms 2 are provided, and at least two groups of transfer mechanisms 2 are arranged along a second direction perpendicular to the first direction to alternately transport the workpieces 5. The second direction is the left-right direction shown in FIG. 6 .

[0083] In one embodiment, two groups of transfer mechanisms 2 are provided. When one group of transfer mechanisms 2 transports the workpiece 5 to the curing chamber 12 for curing, the other group of transfer mechanisms 2 moves to the cooling chamber 13 to cool the workpiece 5, and immediately returns to the preheating chamber 11 after cooling to receive the next workpiece 5.

[0084] Generally, the curing process takes a long time, and two sets of transfer mechanisms 2 can meet the alternating conveying requirements, so that the curing operation can be continuously performed in the curing cavity 12 .

[0085] In some other embodiments, when two groups of transfer mechanisms 2 cannot meet the alternating conveying requirements, three or more groups of transfer mechanisms 2 may be provided.

[0086] At least the transfer mechanism 2 is arranged in the left and right direction. In order to save the light source module 4, only one set of light source module 4 can be set. It is only necessary to increase the left and right moving stroke of the curing light 41 so that the curing light 41 can be moved above the carrier 21 of each transfer mechanism 2.

[0087] In order to allow the waste heat to heat the preheating cavity 11 to the required temperature and reduce the opening of the second heater in the preheating cavity 11, the volume of the preheating cavity 11 should be reduced as much as possible. At least two sets of transfer mechanisms 2 are arranged in the left and right directions. If the size of the preheating cavity 11 is too small, especially when the width in the left and right directions is small, it is easy to cause interference between two adjacent carriers 21 during the up and down movement.

[0088] To solve the above problems, in one embodiment, the transfer mechanism 2 further includes a rotating drive member 23, the fixed end of the rotating drive member 23 is connected to the driving end of the transfer drive member, and the driving end of the rotating drive member 23 is connected to the carrier 21, and is used to drive the carrier 21 to rotate around the axis in the third direction so that two adjacent carriers 21 avoid each other, and the third direction is perpendicular to the first direction and the second direction. Among them, the third direction is the front-to-back direction shown in Figure 6, and the rotating drive member 23 can be a rotating cylinder.

[0089] After the workpiece 5 on the carrier 21 in the cooling chamber 13 is removed, the carrier 21 is driven to move upward in a horizontal state. After leaving the ejection device 3 for a certain distance, the rotating drive member 23 is started to drive the carrier 21 to rotate, so that the carrier 21 is tilted or even reaches a vertical state, so as to reduce the space occupied by the carrier 21 in the left and right directions, so that it can be staggered with another adjacent carrier 21 and rise into the preheating chamber 11.

[0090] In order to facilitate the installation of the rotating driving member 23, the transfer mechanism 2 further includes a connecting block 24, which is slidably connected to the guide column 22, and the fixed end of the rotating driving member 23 is arranged on the connecting block 24. Optionally, the guide columns 22 at both ends of the carrier 21 are provided with connecting blocks 24 and the rotating driving member 23, so as to more easily drive the carrier 21 to rotate.

[0091] In one embodiment, the transfer mechanism 2 further includes a support frame 25, which is disposed on the back of the carrier 21 and is used to support the carrier 21. The support frame 25 extends outward to form a rotating shaft, which is connected to the driving shaft of the rotating driving member 23, so that the rotating shaft is driven to rotate by the rotating driving member 23, thereby driving the support frame 25 and the carrier 21 to rotate.

[0092] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
