Description

Technical Field

[0001] This utility model relates to the field of display panel manufacturing technology, and in particular to a panel heat drying device. Background Technology

[0002] In the process of producing a display panel, a circuit structure needs to be set on one side of a light-transmitting substrate to form a semi-finished display panel. Then, the semi-finished panel needs to be heated to solidify the circuit structure included in the semi-finished panel.

[0003] like Figure 1 As shown, in related technologies, a hot oven 1' is typically used to heat-dry the panels of semi-finished products. Specifically, the hot oven 1' is equipped with support platforms 2' arranged at intervals along the vertical direction L. A hot air heating mechanism is provided on one side of the hot oven 1' along the horizontal direction. During heat drying, the panels of semi-finished products are placed on the support platforms 2', and then the door of the hot oven 1' is closed, so that the hot air heating mechanism 3' blows hot air from one side of the semi-finished product panel along the horizontal direction into the interior of the hot oven 1'.

[0004] However, when using the existing hot oven 1' to heat-bake the panel, two problems are usually encountered. One is that the circuit structure on the panel will generate certain volatiles during the heat-bake curing process. These volatiles will further solidify and form impurities. After the heat-bake is finished, the impurities formed by the solidification of the volatiles are easy to fall downwards, causing impurities to easily adhere to the surface of the circuit structure of the panel at the lower part of the hot oven 1'. The other is that the space inside the hot oven 1' is relatively large, making it difficult for the hot air heating mechanism 3' to blow hot air into the interior of the hot oven 1' from one side along the horizontal direction. This makes it difficult to achieve a roughly the same temperature at different locations inside the hot oven 1', resulting in uneven curing of the panel's circuit structure. Utility Model Content

[0005] The purpose of this invention is to provide a panel heat drying device that can reduce the possibility of impurities adhering to the surface of the circuit structure of the panel during the heat drying process, and can improve the curing uniformity of the circuit structure of the panel.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A panel heating and drying apparatus is provided, comprising:

[0008] Hot drying oven;

[0009] A partition, wherein multiple partitions are arranged vertically at intervals inside the hot drying oven to divide the internal space of the hot drying oven into multiple independent hot drying chambers;

[0010] A hot air heating mechanism, connected to each of the drying chambers, and capable of supplying hot air to each of the drying chambers; and,

[0011] Multiple heating platforms are provided, each corresponding to one of the heating chambers. The heating platforms are connected to the control circuit and are used to support and heat the panel.

[0012] In one embodiment, the heating platform is provided with a plurality of arrayed clearance holes, and the panel heating device further includes a lifting support mechanism. The lifting support mechanism includes a plurality of spaced array support pins and a driving component. The support pins are slidably inserted through the clearance holes one by one, and the driving component is connected to the support pins and can drive the support pins to rise and fall along the vertical direction.

[0013] In one embodiment, the lifting support mechanism further includes a support plate with a plurality of support pins, and the driving member is connected to the support plate and can drive the support plate to move up and down in the vertical direction.

[0014] In one embodiment, the heating stage is equipped with a temperature sensor.

[0015] In one embodiment, the heating stage includes multiple heating sub-plates, each of which is connected to the control circuit.

[0016] In one embodiment, each of the heating sub-plates is provided with a temperature sensor, which is also connected to the control circuit.

[0017] In one embodiment, the heating sub-plate is polygonal, and at least some of the sharp corners of the heating sub-plate are provided with clearance grooves, and the clearance grooves of adjacent heating sub-plates are connected to form clearance holes.

[0018] The panel heating and drying equipment also includes a lifting support mechanism, which includes a plurality of spaced array support pins and a driving component. The support pins are slidably inserted through the clearance holes, and the driving component is connected to the support pins and can drive the support pins to move up and down along the vertical direction.

[0019] In one embodiment, the hot air heating mechanism includes an air supply pipe, a heater, and a hot air fan. The air supply pipe includes a main air supply pipe and multiple sub-pipes connected to the main air supply pipe. Each sub-pipe is connected to a corresponding heating chamber. The heater is located on the main air supply pipe and is used to heat the air in the main air supply pipe. Each sub-pipe is equipped with a hot air fan, which is used to transport the air in the sub-pipe to the heating chamber. Both the heater and the hot air fan are connected to the control circuit.

[0020] In one embodiment, each of the hot drying chambers has an exhaust port on the side away from the hot air heating mechanism.

[0021] In one embodiment, the panel heating and drying equipment further includes an exhaust pipe, which includes a main exhaust pipe and a plurality of exhaust sub-pipes connected to the main exhaust pipe, and each of the exhaust sub-pipes is connected to the exhaust port of each of the heating and drying chambers.

[0022] The beneficial effects of this utility model are:

[0023] This utility model discloses a panel hot drying device. By setting a partition inside the hot drying oven, the interior of the hot drying oven is divided into multiple independent hot drying chambers. A heating platform is set in each hot drying chamber so that the volatiles generated by the panel during the hot drying process will solidify and fall downward onto the partition, instead of falling onto the circuit structure surface of other panels located vertically below.

[0024] Furthermore, by dividing the interior of the hot oven into multiple smaller hot drying chambers using partitions and connecting the hot air heating mechanism to each hot drying chamber, the heating uniformity of the hot air heating mechanism in each hot drying chamber can be improved. At the same time, by enabling the heating platform to generate heat under the control of the control circuit to simultaneously heat the supported panel, the temperature uniformity of each position on the panel can be further improved, thereby improving the curing uniformity of the panel's circuit structure.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] like Figure 2 As shown, this embodiment provides a panel drying device, including a drying oven 1, partitions 2, a hot air heating mechanism 3, and multiple heating platforms 4. The partitions 2 are arranged at intervals along the vertical direction L inside the drying oven 1 to divide the internal space of the drying oven 1 into multiple independent drying chambers 10. The hot air heating mechanism 3 is connected to each drying chamber 10 and can deliver hot air to each drying chamber. Each heating platform 4 is respectively arranged in each drying chamber 10. The heating platform 4 is connected to the control circuit and is used to support and heat the panel.

[0045] By setting a partition 2 inside the hot oven 1, the interior of the hot oven 1 is divided into multiple independent hot oven chambers 10. A heating platform 4 is set in each hot oven chamber 10, so that the volatiles generated by the panel during the hot baking process will fall down onto the partition 2 after solidification, instead of falling onto the circuit structure surface of other panels located below in the vertical direction L.

[0046] Furthermore, by using partition 2 to divide the interior of the hot oven 1 into multiple smaller hot drying chambers 10, and connecting the hot air heating mechanism 3 to each hot drying chamber 10, the heating uniformity of each hot drying chamber 10 can be improved. At the same time, by enabling the heating platform 4 to generate heat under the control of the control circuit to simultaneously heat the supported panel, the temperature uniformity of each position of the panel can be further improved, thereby improving the curing uniformity of the circuit structure of the panel.

[0047] The target heating temperature of the heating platform 4 and the hot air heating mechanism 3 is approximately the same, so that the heating temperature of each part of the panel is relatively uniform.

[0048] Furthermore, it is understood that when the panel is placed on the heating platform 4, specifically the light-transmitting substrate of the panel is placed on the heating platform 4, and the circuit structure of the panel is located on the upper side of the light-transmitting substrate away from the heating platform 4. This can, on the one hand, prevent the circuit structure from contacting the heating platform 4 and deforming or being damaged, and on the other hand, allow the hot air delivered by the hot air heating mechanism 3 to blow directly onto the circuit structure. As a result, the heat convection efficiency in the environment near the circuit structure is high during the hot drying process, and the hot drying efficiency is high.

[0049] It should be noted that the aforementioned vertical direction L specifically refers to the direction parallel to the direction of gravity when the panel heating and drying equipment is in use. The up-down direction along the vertical direction L is the up-down direction along the direction of gravity when the panel heating and drying equipment is in use. Figure 2 The arrows in the diagram indicate the vertical direction L and the up and down directions along the vertical direction L.

[0050] Optionally, the heating platform 4 can be mounted on the partition 2 or connected to the inner wall of the hot oven 1 to make the relative position of the heating platform 4 and the hot oven 1 more stable.

[0051] Please see also Figures 2 to 4 Optionally, the heating platform 4 is provided with multiple arrayed clearance holes 40. The panel heating equipment also includes a lifting support mechanism 5, which includes multiple spaced array support pins 50 and a driving member 51. The support pins 50 are slidably inserted through the clearance holes 40, and the driving member 51 is connected to the support pins 50. The driving member 51 can drive the support pins 50 to rise and fall vertically in the direction L. Thus, before and after heating, the driving member 51 can drive the support pins 50 to rise above the heating platform 4, so that the panel can be placed on top of the support pins 50. In other words, a certain gap can be formed between the panel placement position and the surface of the heating platform 4, which facilitates the panel transfer device to support the panel from below for panel placement operations. For easy observation, Figure 2 The driver component 51 is omitted.

[0052] Optionally, the drive unit 51 may be disposed on the partition 2 or connected to the inner wall of the hot oven 1 so that the relative position of the drive unit 51 and the hot oven 1 is more stable.

[0053] In one alternative embodiment, the drive member 51 can be directly connected to the support pin 50 to directly drive the support pin 50 to rise and fall.

[0054] like Figure 3 and Figure 4 As shown, in another optional embodiment, the lifting support mechanism 5 further includes a support plate 52, on which a plurality of support pins 50 are provided. A driving member 51 is connected to the support plate 52, and the driving member 51 can drive the support plate 52 to rise and fall in the vertical direction L. Thus, the driving member 51 can be connected to the plurality of support pins 50 through the support plate 52 and drive the plurality of support pins 50 to rise and fall at the same time. On the one hand, this simplifies the driving structure of the plurality of support pins 50, and on the other hand, it improves the consistency of the lifting height of the plurality of support pins 50.

[0055] Please combine Figure 5 As shown, optionally, the heating platform 4 is equipped with a temperature sensor 6, which is also connected to the control circuit. The temperature sensor 6 can detect the actual heating temperature of the panel carried by the heating platform 4, so that the control circuit can adjust the heating power of the heating platform 4 in a timely manner according to the actual heating temperature detected by the temperature sensor 6, and avoid the actual heating effect of the heating platform 4 on the panel being too small or too large.

[0056] Optionally, the heating platform 4 includes multiple heating sub-plates 41, each of which is connected to a control circuit. This allows the control circuit to control the heating power of each heating sub-plate 41, enabling more flexible adjustment of the heating effect of the heating platform 4 on different areas of the supported panel. It also allows for more flexible compensation of the uneven heating effect of the hot air heating mechanism 3 through the individual heating sub-plates 41.

[0057] Optionally, each heating sub-plate 41 is equipped with a temperature sensor 6, which allows the actual heating temperature of the supported panel by each heating sub-plate 41 to be detected. This enables the control circuit to flexibly adjust the heating power of each heating sub-plate 41 based on the actual heating temperature detected by the temperature sensor 6. Optionally, the temperature sensor 6 can also be connected to the control circuit so that the control circuit can directly receive the heating temperature data detected by the temperature sensor 6.

[0058] Optionally, the heating stage 4 and the heating sub-plate 41 may include any existing heating plate capable of generating heat when powered by the control circuit, such as including but not limited to mica heating plates and carbon crystal heating plates.

[0059] When the panel heating equipment described in the aforementioned technical solution further includes a support pin 50, and the support pin 50 can be slidably inserted into the clearance hole 40, optionally, the heating sub-plate 41 is polygonal, and at least some of the sharp corners of the heating sub-plate 41 are provided with clearance grooves 410. The clearance grooves 410 of adjacent heating sub-plates 41 are connected to form clearance holes 40, thereby forming clearance grooves 410 at the corners of the heating sub-plate 41, so that multiple adjacent clearance grooves 410 can be connected to form clearance holes 40 for the support pin 50 to pass through. Moreover, the clearance grooves 410 occupy less space on the heating sub-plate 41 and are easier to set on the heating sub-plate 41.

[0060] Please continue to see [the website / information]. Figure 2 Optionally, the hot air heating mechanism 3 includes an air supply pipe 30, a heater 31, and a hot air fan 32. The air supply pipe 30 includes a main air supply pipe 301 and multiple sub-pipes 302 connected to the main air supply pipe 301. Each sub-pipe 302 is connected to each of the heating chambers 10. The heater 31 is located in the main air supply pipe 301 and is used to heat the air in the main air supply pipe 301. Each sub-pipe 302 is equipped with a hot air fan 32. The fan 32 is used to transport the air in the air supply sub-pipe 302 to the hot drying chamber 10. The heater 31 and the hot air fan 32 are both connected to the control circuit, so that the air volume of the hot air obtained in each hot drying chamber 10 can be controlled by each hot air fan 32, so that the air volume of the hot air obtained in each hot drying chamber 10 is more consistent. The hot air fan 32 can be installed in the air supply sub-pipe 302, or the air supply sub-pipe 302 can be connected to the hot drying chamber 10 through the hot air fan 32.

[0061] Optionally, each hot drying chamber 10 is provided with an exhaust port 11 on the side away from the hot air heating mechanism 3, so that the hot air that has completed a certain heat exchange can be discharged from the side away from the hot air heating mechanism 3. This helps to maintain the air pressure in the hot drying chamber 10 and makes it easier for the hot air heating mechanism 3 to deliver the hot air to the hot drying chamber 10 more smoothly.

[0062] Optionally, the panel heat drying equipment also includes an exhaust pipe 7, which includes an exhaust main pipe 71 and multiple exhaust sub-pipes 72 connected to the exhaust main pipe 71. Each exhaust sub-pipe 72 is connected to the exhaust port 11 of each heat drying chamber 10, so that the gas discharged from each heat drying chamber 10 can be collected into the exhaust main pipe 71, so as to uniformly process and discharge the gas discharged from each heat drying chamber 10.

[0063] For the panel to be placed and removed, the hot oven 1 includes an openable and closable door (not shown in the figure). The door can be any existing structure that can be opened and closed, and can seal the space inside the hot oven 1 when closed, which will not be described in detail here.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
