[0002] During the processing of ceramic sheets, silver paste is applied. Applying silver paste to ceramic sheets involves coating the surface of the ceramic sheet with silver paste through processes such as screen printing to form a conductive layer or electrode. This process is mainly used to make electrodes or circuits for electronic components.

[0003] Traditional ceramic sheet silver paste brushing equipment relies on frequent manual replenishment of materials such as ceramic sheets and aluminum plates, and requires manual placement of materials one by one at the processing station, resulting in long material interruption times and low production efficiency.

[0004] Therefore, we urgently need a silver paste brushing machine with continuous feeding. Utility Model Content

The patching mechanism includes a patch cylinder, and a rejection suction cup is installed at the bottom of the patch cylinder; The upper aluminum plate mechanism includes a lifting module, and a spring clip-type hopper is installed on the top of the lifting module; The flipping and conveying mechanism includes a second X, Y, Z three-axis module. A flipping seat is installed on the outside of the second X, Y, Z three-axis module. A flipping suction cup is rotatably connected to the inside of the flipping seat. A rotary cylinder is installed at one end of the flipping suction cup. The silver paste brushing mechanism includes a silver paste brushing frame, one end of which is equipped with a third X, Y, Z three-axis module. A brushing machine is installed on the outside of the third X, Y, Z three-axis module, and a wire mesh is provided on the inside of the silver paste brushing frame. The material handling mechanism includes a fourth X, Y, Z three-axis module, and a material handling robot is installed at one end of the fourth X, Y, Z three-axis module.

[0007] Preferably, the positioning plate has a tapered hole that matches the edge of the ceramic sheet.

[0008] Preferably, of the plurality of industrial cameras, at least one industrial camera is positioned toward the positioning fixture, and at least one industrial camera is positioned toward the screen.

[0009] Preferably, the positioning fixture is fixedly connected to the inner side of the frame.

[0011] Preferably, an oven conveyor line is provided on the side of the frame.

[0012] Preferably, a feeding bin is fixedly connected to the inner side of the frame.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: Firstly, this utility model achieves continuous automated operation of the ceramic sheet silver paste brushing process by batching ceramic sheets into a ceramic sheet hopper, stacking aluminum plates into a spring clip hopper, and placing a material tray into a tooling fixture. The ceramic sheet feeding mechanism automatically picks up and transports the ceramic sheets to the positioning fixture via a first X, Y, Z three-axis module driven by a first suction cup. The positioning mechanism automatically corrects and fixes the position of the ceramic sheets. After the vision inspection mechanism automatically identifies broken ceramic sheets, the replacement mechanism can automatically remove the broken pieces and the ceramic sheet feeding mechanism can replenish complete ceramic sheets from the replacement hopper. The aluminum plate feeding mechanism automatically conveys the aluminum plates, and the flipping and conveying mechanism automatically flips and accurately transports them to the silver paste brushing station. The silver paste brushing mechanism automatically adjusts the position and applies silver paste. The conveying mechanism automatically transports the finished products to the oven conveyor line. This significantly reduces manual intervention and improves production efficiency.

[0014] Secondly, this utility model uses a lifting cylinder driven by a positioning mechanism to drive a second suction cup that engages with a conical hole on a positioning plate that matches the edge of the ceramic sheet. This automatically corrects the position of the ceramic sheet and secures it, preventing displacement in subsequent processes. The visual inspection mechanism can identify broken ceramic sheets in advance, and the replacement mechanism promptly removes and replaces them with complete pieces, preventing broken pieces from entering the silver paste application process and affecting the coating quality or scratching the equipment. Before applying the silver paste, an industrial camera facing the screen in the visual inspection mechanism takes a visual impression of the ceramic sheet. The controller adjusts the relative position of the brushing machine and the screen through a third X, Y, and Z three-axis module to ensure precise alignment of the screen mesh with the center of the ceramic sheet, resulting in uniform and concentric silver paste coating. After applying the silver paste, the system can also detect screen adhesion issues and trigger an alarm to prevent adhesion from affecting the coating effect of subsequent products, thereby effectively improving the product qualification rate.

A rotary cylinder 74 is installed at one end of the flipping suction cup 73. The silver paste brushing mechanism 8 includes a silver paste brushing frame 81, a third X, Y, Z three-axis module 82 is installed at one end of the silver paste brushing frame 81, a brushing machine 83 is installed on the outside of the third X, Y, Z three-axis module 82, and a wire mesh 84 is provided on the inside of the silver paste brushing frame 81. The handling mechanism 9 includes a fourth X, Y, Z three-axis module 91, and a handling robot 92 is installed at one end of the fourth X, Y, Z three-axis module 91.

[0019] The positioning plate 34 has a tapered hole that matches the edge of the ceramic sheet.

[0020] Of the plurality of industrial cameras 42, at least one industrial camera 42 is positioned toward the positioning fixture 31 and at least one industrial camera 42 is positioned toward the screen 84.

[0021] The positioning fixture 31 is fixedly connected to the inside of the frame 1.

[0022] There are two silver paste brush holders 81, and both silver paste brush holders 81 are fixedly connected to the inside of the frame 1.

[0023] The side of the frame 1 is equipped with an oven conveyor line 10.

[0024] The inner side of the frame 1 is fixedly connected to a feeding bin 53.

[0025] Its working principle is as follows: Ceramic sheets are manually placed in batches into the ceramic sheet hopper 23, aluminum plates are stacked and placed into the spring-loaded hopper 62 of the upper aluminum plate mechanism 6, and the material tray is placed into the corresponding tooling fixture. Then, the upper ceramic sheet mechanism 2 is activated, and its first X, Y, Z three-axis module 21 drives the first suction cup 22 to move above the ceramic sheet hopper 23. After the ceramic sheets are adsorbed by negative pressure, they are transported to the positioning plate 34 on the positioning fixture 31 of the positioning mechanism 3. Next, the lifting cylinder 32 drives the second suction cup 33 to move upwards. The position of the ceramic sheets is corrected by using the conical holes on the positioning plate 34 that match the edge of the ceramic sheet. Simultaneously, the second suction cup 33 uses negative pressure to stably fix the corrected ceramic sheets, preventing displacement in subsequent processes and ensuring positioning accuracy. Afterwards, the visual inspection mechanism 4... An industrial camera 42, positioned inside the protective cover 41 and facing the positioning fixture 31, captures images of the ceramic sheet. Image recognition determines whether the ceramic sheet is broken. If a broken ceramic sheet is detected, the patching cylinder 51 of the patching mechanism 5 drives the removal suction cup 52 to move above the positioning fixture 31, adsorbing the broken ceramic sheet and removing it to the waste area. Simultaneously, the first X, Y, Z three-axis module 21 of the ceramic sheet feeding mechanism 2 drives the first suction cup 22 to move above the feeding bin 53 fixedly connected to the inner side of the frame 1, picking up intact ceramic sheets and replenishing them into the positioning fixture 31. This achieves automatic processing of broken parts and continuous material replenishment. After patching, the lifting module 61 of the aluminum plate feeding mechanism 6 drives the spring-loaded hopper 62 to rise layer by layer, placing the aluminum plate at a height suitable for pickup. Then, the first suction cup 22... 2. The aluminum plate is picked up and placed over the ceramic sheet in the positioning fixture 31. Then, the second X, Y, Z three-axis module 71 of the flipping and conveying mechanism 7 drives the flipping seat 72 to move above the positioning fixture 31. The flipping suction cup 73 simultaneously adsorbs the aluminum plate and the ceramic sheet through negative pressure. Then, the rotary cylinder 74 drives the flipping suction cup 73 to flip 180 degrees, so that the ceramic sheet faces upward to meet the requirements of silver paste application. Then, the second X, Y, Z three-axis module 71 accurately transports the flipped aluminum plate and ceramic sheet to the corresponding silver paste application station of the two fixedly connected silver paste application frames 81 inside the frame 1. After reaching the silver paste application station, the industrial camera 42 in the vision inspection mechanism 4, which is set towards the screen 84, performs visual imaging of the ceramic sheet position, obtains the center coordinate data of the ceramic sheet, and transmits it to the equipment control. The controller controls the third X, Y, Z axis module 82 of the silver paste brushing mechanism 8 to adjust the relative position of the brushing machine 83 and the screen 84, ensuring that the mesh of the screen 84 is precisely aligned with the center of the ceramic sheet. Then, the brushing machine 83 starts, evenly coating the surface of the ceramic sheet with silver paste through the screen 84. After the silver paste is brushed, the industrial camera 42 facing the screen 84 checks again whether there is any material adhering to the screen 84. If there is, the equipment alarms to prompt manual removal of the screen 84. If not, the flipping mechanism 7 drives the ceramic sheet after silver paste brushing to reset. Then, the fourth X, Y, Z axis module 91 of the transport mechanism 9 drives the transport robot 92 to move above the flipping suction cup 73, adsorbs the silver paste-brushed ceramic sheet and aluminum plate, and smoothly transports them to the oven conveyor line 10 set on the side of the frame 1.The ceramic sheet is conveyed to the subsequent drying oven by the oven conveyor line 10, thus completing the continuous automated operation of the ceramic sheet from feeding, positioning, inspection and patching, aluminum plate covering, flipping and handling, silver paste application to subsequent conveying. This effectively reduces manual intervention and avoids positioning deviations or material breaks caused by human operation errors, thereby improving the production efficiency and product qualification rate of the ceramic sheet silver paste application process.
