Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a coating mold for processing ceramic substrates. Background Technology

[0002] Ceramic substrates possess excellent insulation properties, superior high-temperature resistance, high strength and hardness, outstanding chemical stability, and good machinability. They effectively isolate circuits, withstand high temperatures and chemical corrosion, and meet complex processing and high-precision dimensional requirements. By filling the gaps between the ceramic substrate and the heat source / heat sink with thermally conductive grease, the thermal resistance of the ceramic substrate can be effectively reduced by 13-15%. Most ceramic substrate thermal grease application is done manually, requiring custom-made equipment, which is expensive and places high demands on the work site and operators.

[0010] Preferably, each set of replenishment boxes has an observation window installed through the front side, a pressure box installed at the top of each set of replenishment boxes, an output conduit sealed on the corresponding sides of the two sets of replenishment boxes, and a replenishment pipe installed on the outside of each set of replenishment boxes.

[0011] Preferably, a set of grooves is provided on the upper part of the left and right sides of the force-bearing base, and a set of jacks is installed inside each set of grooves. A set of limiting seats is installed on the lower part of the grooves on the left and right sides of the force-bearing base, and a limiting rod is fixedly installed on the top of the limiting seat. A limiting plate is fixedly bolted to the limiting rod.

[0012] Preferably, the movable plate has another set of slots corresponding to the slots opened on the left and right sides of the force-bearing base. The telescopic top of the jack is bolted to the inner wall of the slots on the left and right sides of the movable plate. A set of limiting sleeves is installed on the left and right sides of the movable plate corresponding to the limiting seat positions. The two sets of limiting sleeves are respectively fitted onto the outer arc surface of the corresponding side limiting rod.

[0013] Preferably, a set of electric slides is embedded in the middle of both the force-bearing base and the moving plate. Two sets of mounting seats are installed on the left and right sides of each set of electric slides, and the mounting seats on the upper and lower sides are movably fitted together.

[0014] Preferably, the upper and lower sets of coating racks are bolted to the load-bearing base and the front mounting seat of the movable plate, respectively. The coating rack has a through-hole in the center, and the inner wall of the mounting hole has symmetrical side grooves.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The key to improving processing efficiency lies in the synchronous operation of two sets of working feed boxes. A precise control system ensures that both feed boxes can simultaneously coat both sides of the ceramic substrate. This simultaneous coating method significantly shortens the coating time compared to traditional single-sided coating. Furthermore, synchronous coating ensures consistency and uniformity of coating on both sides of the substrate, improving product quality.

[0021] Furthermore, the electric slide table provides high-precision vertical displacement control. Its advanced drive system and precise displacement sensors ensure that the vertical movement error of the working feed box is controlled within a minimal range. This allows the pressure plate to be accurately inserted into the container rack, guaranteeing the accuracy of the starting position of the coating operation and laying the foundation for subsequent uniform coating. The movable design of the container rack within the coating rack, combined with the lifting control component, brings great flexibility to the coating operation. The synchronizer in the lifting control component can precisely synchronize the movements of the two sets of first electric push rods, ensuring smooth lifting and lowering of the container rack. Operators can easily and quickly adjust the spacing between the two sets of stencils according to the different specifications of the ceramic substrate and the coating thickness requirements. This flexible spacing adjustment function allows the mold to adapt to diverse coating needs, improving the mold's versatility and applicability. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 This utility model provides a coating mold for ceramic substrate processing, including a force-bearing base 1 and two sets of replenishing boxes 2 symmetrically installed on the upper surface of the force-bearing base 1, a movable plate 11 movably installed on the upper part of the force-bearing base 1, two sets of coating racks 15 respectively installed on the front side of the force-bearing base 1 and the movable plate 11, a set of working feed boxes 25 movably installed corresponding to each set of coating racks 15, and pressure plates 28 installed on the output side of the working feed boxes 25 corresponding to each side of the coating racks 15. The replenishing boxes 2 can effectively replenish the coating material to the working feed boxes 25, so that the working feed boxes 25 can... It can work continuously, avoiding material interruption during use. The movable plate 11 on the upper part of the force base 1 can be raised and lowered to control the usage interval of the two sets of coating racks 15, making it more convenient to put and take ceramic substrates. The pressure plate 28 installed at the bottom of the working feed box 25 can perform the function of pressing the material, making the coating work more efficient and convenient. The pressure plate 28 can complete the coating work on the ceramic substrate at a fixed point. In addition, the two sets of working feed boxes 25 work synchronously, and can coat both sides of the ceramic substrate at one time, greatly improving the processing efficiency.

[0030] A holding rack 23 is movably installed inside the coating rack 15. A stencil 24 is embedded inside the holding rack 23. The two sets of coating racks 15 are movably fitted together. The holding rack 23 installed inside the coating rack 15 can connect with the pressure plate 28, so that the pressure plate 28 can be fully inserted. The coating material is extruded by moving the sealing plate 26.

[0031] The other side of each working feed box 25 corresponding to the pressure plate 28 is open, and a movable sealing plate 26 is slidably installed on the inner wall of the open side of the working feed box 25. The two working feed boxes 25 are respectively connected to a replenishment box 2. The movable sealing plate 26 is attached to the inner wall of the working feed box 25, which can prevent the coating material from being squeezed out when the movable sealing plate 26 moves, thus improving the overall safety of the device.

[0032] The pressure plate 28 has several sets of leakage holes 29 in the center, and each set of leakage holes 29 has a set of conical rubber heads 30 embedded inside. The conical rubber heads 30 have cross openings, which are based on the principle of heart valves and are similar to the structure of common scream bottle mouths. They need to be opened by external pressure to improve their protection of the coating material.

[0033] In a further preferred embodiment, such as Figure 2 As shown, each set of replenishment boxes 2 has an observation window 3 installed through the front side, and a pressure box 4 installed at the top of each set of replenishment boxes 2. Each set of two sets of replenishment boxes 2 has an output conduit 5 sealed on the corresponding side. Each set of replenishment pipes 6 is installed on the outside of each set of replenishment boxes 2. The observation window 3 installed at the front of the replenishment box 2 allows the staff to see the remaining material inside the replenishment box 2 in real time, and allows the staff to replenish the inside of the replenishment box 2 through the replenishment pipe 6. The pressure box 4 installed at the top of the replenishment box 2 can pressurize the replenishment box 2, and continuously squeeze the coating material into the working feed box 25 to complete the material replenishment of the working feed box 25.

[0034] In this embodiment, as Figure 2 As shown, a set of slots is opened on the upper part of the left and right sides of the force-bearing base 1, and a set of jacks 7 is installed in each set of slots. A set of limiting seats 8 is installed on the lower part of the slots on the left and right sides of the force-bearing base 1. A limiting rod 9 is fixedly installed on the top of the limiting seat 8, and a limiting plate 10 is fixedly bolted to the limiting rod 9. The height of the moving plate 11 can be controlled by the jacks 7. The jack 7 is an Enerpac RAR-50, which is a hydraulic, high-precision jack that can accurately control the height of the moving plate 11, making it easier for workers to remove the ceramic substrates inside the two sets of coating racks 15. The limiting seats 8, limiting rods 9 and limiting plates 10 are all set to limit the moving plate 11 and ensure the stability of the moving plate 11.

[0035] It is worth noting that, such as Figure 2As shown, the movable plate 11 has another set of slots corresponding to the slots opened on the left and right sides of the force-bearing base 1. The telescopic top of the jack 7 is bolted to the inner wall of the slots on the left and right sides of the movable plate 11. A set of limiting sleeves 12 is installed on the left and right sides of the movable plate 11 corresponding to the positions of the limiting seats 8. The two sets of limiting sleeves 12 are respectively sleeved on the outer arc surface of the corresponding side limiting rods 9. The limiting sleeves 12 cooperate with the limiting rods 9 to prevent the movable plate 11 from being misaligned when it slides up and down, which would cause the two sets of coating racks 15 to be misaligned and unable to stably coat the ceramic substrate.

[0036] Specifically, such as Figure 2 As shown, a set of electric slide tables 13 are embedded in the middle of the force-bearing base 1 and the moving plate 11. Two sets of mounting seats 14 are installed on the left and right sides of each set of electric slide tables 13. The upper and lower mounting seats 14 are movably fitted together. The electric slide tables 13 can stably control the working height of the working feed box 25, so that the working feed box 25 can move downward to align with the holding rack 23 to ensure that the pressure plate 28 is inserted into the holding rack 23, making the coating operation more accurate.

[0037] Furthermore, such as Figure 3 and Figure 4 As shown, the upper and lower coating racks 15 are bolted to the force-bearing base 1 and the front mounting seat 14 of the moving plate 11, respectively. The coating rack 15 has a through-hole in the center, and the inner wall of the mounting hole has symmetrical side grooves 16. The container rack 23 is movably installed inside the mounting hole. The filter plate 24 is fixedly installed inside the container rack 23. The mounting hole limits the container rack 23, and the side grooves 16 limit the second connecting plate 22 to ensure that the container rack 23 can move inside the mounting hole, thereby adjusting the usage distance between the two sets of filter plates 24 and thus changing the overall coating state of the device.

[0038] Furthermore, such as Figure 4 As shown, a set of lifting control components is installed on the left and right sides of the coating rack 15. The lifting control components include mounting plates 17. A synchronizer 18 is bolted to the surface of each mounting plate 17. Two sets of first electric push rods 19 are synchronously installed on both sides of the synchronizer 18. The mounting plates 17 limit the synchronizer 18 and the first electric push rods 19. When the two sets of first electric push rods 19 work, the overall lifting of the container rack 23 is controlled. The synchronizer 18 can synchronize the two sets of first electric push rods 19 to work, thereby improving the overall controllability of the container rack 23.

[0039] Preferred, such as Figure 4As shown, a first connecting plate 20 is bolted to the telescopic end of the first electric push rod 19. A pressure rod 21 is installed on the surface of the first connecting plate 20 corresponding to the first electric push rod 19. A second connecting plate 22 is bolted to the bottom of both pressure rods 21. The second connecting plate 22 is movably installed inside the side groove 16 and is bolted to the surface of the holding rack 23. The first connecting plate 20 can synchronize the movement of the first electric push rod 19 and the second connecting plate 22, so that the first electric push rod 19 can stably control the movement of the second connecting plate 22, thereby better controlling the holding rack 23.

[0040] In addition, such as Figure 5 As shown, the working feed box 25 and the replenishment box 2 are connected and installed through the output conduit 5. The movable sealing plate 26 is located inside the working feed box 25 and a rubber layer 27 is fixedly installed on one side. The rubber layer 27 is set to fit against the inner wall of the working feed box 25. The rubber layer 27 installed at the bottom of the movable sealing plate 26 further improves the sealing performance and can also push down the coating material adhering to the inner wall of the working feed box 25, further improving the efficiency of material use.

[0041] It is worth noting that, such as Figure 5 As shown, each set of working feed boxes 25 has two additional sets of lifting control components installed on the left and right sides. The internal pressure rod 21 of the lifting control components installed on both sides of the working feed box 25 is bolted to the movable sealing plate 26. The lifting control components installed on both sides of the coating rack 15 and the working feed box 25 use the first electric push rod 19 and the second electric push rod 31, respectively. The two electric push rods have different strokes. The second electric push rod 31 has a longer stroke, which can better push the movable sealing plate 26 to move, thereby pressing out the coating material inside the working feed box 25. The first electric push rod 19 uses the JPT-500 model, and the second electric push rod 31 uses the ADS-1000 model. They both have the advantages of high cost performance and are suitable for light industrial or commercial use.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
