Description

Technical Field

[0001] This utility model relates to the technical field of the workbench device of a differential pressure coating machine, and particularly to a cooling structure for the workbench device of a differential pressure coating machine and the differential pressure coating machine itself. Background Technology

[0002] A differential pressure coating machine is a device that uses a pressure difference to coat a product with a diaphragm. It includes a worktable and a coating reaction chamber positioned vertically opposite to the worktable. Its working principle is as follows:

[0003] First: The coating reaction chamber has an upper chamber and a lower chamber. The worktable includes a membrane fixture and a product fixture installed below the membrane fixture. First, the coating reaction chamber covers the worktable, placing the membrane fixture between the upper and lower chambers and separating them (making them disconnected). Next, vacuum is drawn into both the upper and lower chambers, creating vacuum conditions. Then, the membrane fixture is radiantly heated in the upper chamber until it reaches a certain temperature. Next, the product fixture is raised to the bottom of the membrane fixture via a lifting mechanism. Finally, high-pressure gas is introduced into the upper chamber to press the membrane fixture onto the product fixture, thus completing the coating of the product.

[0004] Second: After the product is coated, it is kept warm and pressed (i.e., baked at high temperature and pressed under high pressure for a period of time); finally, the coating reaction chamber opens upward, the product fixture descends and returns to its position, the product is removed, and the next product and membrane are placed in to perform the next coating process.

[0005] For details on the working principle of the differential pressure coating machine, please refer to:

[0006] 1. Chinese invention patent application with patent document number CN115339090A and patent title: A differential pressure coating machine;

[0007] 2. Chinese utility model patent with patent document number CN222360629U and patent title: A double-plate covering reaction chamber support mechanism and covering machine;

[0008] Currently, the worktable device in the differential pressure coating machine has the following defects:

[0009] The current differential pressure coating machine's worktable device lacks a corresponding cooling and temperature control mechanism. This results in either the product fixture in the worktable device continuously overheating, leading to lower coating quality for the next product, or the product fixture in the worktable device requiring a certain amount of time for passive cooling, resulting in long idle times and low production efficiency. Specifically:

[0010] As mentioned in the second point of the working principle of the differential pressure coating machine, the coated product is kept warm and pressurized. During the warm and pressurization process, the product fixture will inevitably be heated. Finally, when the coating reaction chamber is opened and the product on the product fixture is removed, the product fixture is in a high temperature state. However, if there is no relevant cooling and temperature control mechanism, the initial temperature of the product fixture will be very high. At this time, the product fixture must either choose passive heat dissipation, resulting in low production efficiency, or choose to directly place the product for the next coating process, but this will result in poor coating quality. (For example, if a plastic or fiberglass product is initially placed on a high-temperature product fixture, the surface of the plastic or fiberglass product will soften and deform, resulting in incomplete adhesion during coating. Therefore, it is necessary to ensure that the product fixture is within a reasonable temperature range during the time interval from when the product is placed on it until the coating process begins. Thus, it is necessary to ensure that the temperature of the product fixture is below this reasonable temperature range when the next coating process begins, in order to avoid affecting the quality of the next coating process.) Utility Model Content

[0011] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide a cooling structure for the workbench device of a differential pressure coating machine and the differential pressure coating machine itself. After the product coating is completed, the cooling structure of the workbench device can actively dissipate heat from the product fixture, thereby improving production efficiency and ensuring the coating quality of the next product.

[0012] To achieve the above objectives, this utility model includes the following two aspects:

[0013] In a first aspect, this utility model provides a cooling structure for the workbench device of a differential pressure coating machine, including a frame and a workbench mounted on the top of the frame. A slide rod assembly is mounted on the workbench, and a stop plate is slidably connected to the slide rod assembly. A first lifting drive mechanism is mounted at the bottom of the stop plate. A product fixture is mounted on the stop plate, and a diaphragm fixture is mounted above the product fixture. An air intake cooling assembly is mounted at the bottom of the product fixture. An air intake channel structure communicating with the air intake cooling assembly is opened inside the product fixture. Several cooling air holes communicating with the air intake channel structure are opened at the top of the product fixture. A temperature control sensor is mounted on the product fixture.

[0014] Preferably, the diaphragm fixture is mounted on top of the slide bar assembly.

[0015] Preferably, the slide bar assembly includes four slide bars surrounding the edge of the stop plate and slidably connected to the stop plate, and the diaphragm fixture is mounted on the top of the four slide bars.

[0016] Preferably, the air intake cooling assembly includes two air intake cooling pipes installed at the bottom of the product fixture, and the air intake channel structure includes two air intake channels opened inside the product fixture, with the two air intake channels respectively corresponding to and connected to the two air intake cooling pipes.

[0017] Preferably, the air intake channel includes an air intake groove located at the bottom of the product fixture and connected to the air intake cooling pipe, a longitudinal air intake hole located inside the product fixture and connected to the air intake groove, and an air outlet groove located at the top of the longitudinal air intake hole and connected to the longitudinal air intake hole. The air outlet groove is connected to a plurality of cooling air holes.

[0018] Preferably, a plurality of cooling vents are arranged linearly to form a plurality of cooling vent rows, and each cooling vent row has a transverse groove at its bottom that communicates with the cooling vent row, and each transverse groove communicates with the air outlet groove of the air inlet channel.

[0019] Preferably, the product fixture includes a heat-connecting plate mounted on the stop plate and a product carrier plate mounted on the heat-connecting plate.

[0020] Preferably, the air intake cooling component is installed at the bottom of the heat connection plate, the air intake channel structure is opened on the heat connection plate, the temperature control sensor is installed at the bottom of the heat connection plate, and the cooling air hole is opened on the product carrier plate.

[0021] Preferably, the first lifting drive mechanism includes a rotary drive motor mounted on the frame, a lifting transmission linkage assembly mounted on the rotary drive motor, and a lifting rod mounted between the lifting transmission linkage assembly and the stop plate.

[0022] Secondly, this utility model provides a differential pressure coating machine, including a workbench device cooling structure of a differential pressure coating machine as described in the first aspect above, and a coating reaction chamber device arranged vertically opposite to the workbench device cooling structure of the differential pressure coating machine.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. A cooling structure for the workbench device of a differential pressure coating machine according to the present invention, comprising an air intake cooling component installed at the bottom of the product fixture, an air intake channel structure opened inside the product fixture, and a plurality of cooling air holes opened at the top of the product fixture.

[0025] After the product coating is completed and the product fixture is removed, cooling gas can be introduced into the product fixture through the air intake cooling component, and after passing through the air intake channel structure, it is finally sprayed out from the cooling air hole, thereby quickly cooling the product fixture. The temperature control sensor ensures that the product fixture is cooled to a certain reasonable temperature range.

[0026] Therefore, the advantages of this structural design are:

[0027] A. The structure is simple and can be adapted to various types of differential pressure coating machines;

[0028] B. High coating efficiency, ensuring the coating quality of the next product;

[0029] C. Avoid setting the initial temperature of the product fixture too low, as this may affect the coating quality of the next product (if the initial temperature of the product fixture is too low, the adhesive on the bottom of the film will not dry completely when coating the next product, resulting in an unstable coating).

[0030] 2. In summary, the cooling structure of the workbench device and the differential pressure coating machine provided by this utility model can effectively improve coating efficiency and ensure the coating quality of the next product. Attached Figure Description

Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0045] The diaphragm fixture 16 is mounted on top of the slide rod assembly 13.

[0046] The slide bar assembly 13 includes four slide bars 131 surrounding the edge of the stop plate 14 and slidably connected to the stop plate 14, and a diaphragm fixture 16 is mounted on the top of the four slide bars 131.

[0048] The air intake channel 1550 includes an air intake groove 15501 located at the bottom of the product fixture 15 and connected to the air intake cooling pipe 171, a longitudinal air intake hole 15502 located inside the product fixture 15 and connected to the air intake groove 15501, and an air outlet groove 15503 located at the top of the longitudinal air intake hole 15502 and connected to the longitudinal air intake hole 15502.

[0049] A number of cooling vents 1570 are arranged linearly to form a number of cooling vent rows 157. Each cooling vent row 157 has a transverse groove 156 at its bottom that is connected to the cooling vent row 157. Each transverse groove 156 is connected to the air outlet groove 15503 of the air inlet channel 1550.

[0050] Product fixture 15 includes a heat-connecting plate 152 mounted on a stop plate 14 and a product carrier plate 153 mounted on the heat-connecting plate 152.

[0051] The air intake cooling component 17 is installed at the bottom of the heat connection plate 152, the air intake channel structure 155 is opened on the heat connection plate 152, the temperature control sensor 18 is installed at the bottom of the heat connection plate 152, and the cooling air hole 1570 is opened on the product carrier plate 153.

[0052] More specifically, the air inlet slot 15501 is formed at the bottom of the heat connection plate 152, the longitudinal air inlet hole 15502 is formed on the heat connection plate 152, the air outlet slot 15503 is formed at the top of the heat connection plate 152, the transverse slot 156 is formed at the bottom of the product carrier plate 153, and several cooling air holes 1570 are formed on the product carrier plate 153.

[0055] The cooling structure 1 of the workbench device of the differential pressure coating machine according to Embodiment 1 of this utility model has the following technical advantages:

[0056] When the cooling structure 1 of the workbench device of the differential pressure coating machine of this utility model and the coating reaction chamber device 2 of the prior art complete the coating of the product and remove the product, the product fixture 15 is cooled down. At this time, the cooling method is as follows: cooling gas is introduced into the cooling pipe 171 of the cooling pipe 17 of the cooling pipe 17 -> the air inlet groove 15501 of the air inlet channel 155 of the air inlet channel structure 155 -> the longitudinal air inlet hole 15502 -> the air outlet groove 15503 -> the transverse groove 156 -> the cooling air hole arrangement row 157, that is, cooling gas is sprayed out to each cooling air hole 1570, thereby quickly cooling down the product fixture 15, thereby effectively improving the coating efficiency of the next coating and avoiding the product fixture 15 being too hot and affecting the coating quality of the next product.

[0057] In addition, a temperature control sensor 18 is added to control the temperature of the product fixture 15, further precisely controlling the cooling of the product fixture 15, avoiding the initial temperature of the product fixture 15 being far below the reasonable temperature range, thereby avoiding the influence of the low temperature of the product fixture 15 on the drying of the adhesive at the bottom of the film during the next coating, thus avoiding affecting the quality of the next coating.

[0058] In addition, the heat dissipation vents are preferably set to 2mm. Since the vents are small and the amount of cooling air ejected is small, it is only necessary to cool the product fixture 15 to a reasonable temperature range. It is not necessary to cool it too low. Moreover, the surface area of ​​the product fixture 15 is not large, so the amount of cooling air required is small. Therefore, this small amount of cooling air will not affect the clean and tidy environment requirements of the differential pressure coating machine, thus ensuring a dust-free environment and preventing dust from getting on the bottom of the diaphragm.

[0061] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
