Description

Technical Field

[0001] This utility model relates to the field of transparent conductive electrode coating technology, specifically to a thermosetting transparent conductive electrode coating device with thickness adjustment. Background Technology

[0002] Thermosetting transparent conductive electrodes are special materials that combine high light transmittance and conductivity. They are usually made by using thermosetting resins such as epoxy resin as the matrix and combining them with conductive fillers such as silver powder and copper powder.

[0003] Thermosetting transparent conductive electrodes are used in electronic displays, solar cells, touch screens, and other fields. In practical applications, they often need to be coated onto the electrodes of circuit boards. However, due to the different power of electronic devices, the required thickness of the thermosetting transparent conductive electrodes varies. Traditional coating mechanisms are inadequate in adjusting the thickness of thermosetting transparent conductive electrodes, thus failing to meet the needs of coating thermosetting transparent conductive electrodes of different thicknesses for electronic devices with different power levels, and thus failing to meet practical application requirements. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing a thermosetting transparent conductive electrode coating device with adjustable thickness.

[0005] The specific technical solution is as follows: A thermosetting transparent conductive electrode coating device with thickness adjustment includes a base, an mounting block fixedly installed on the right side of the top of the base, a placement plate provided on the top of the base and to the left of the mounting block, mounting frames provided on the front and rear sides of the placement plate, a slot provided on the top of the mounting frame, a pressing rod inserted into the slot, a blocking plate fixedly installed on the left side of the top of the placement plate, and a thermosetting transparent conductive electrode coating mechanism provided on the top of the base and to the left of the placement plate. The thermosetting transparent conductive electrode coating mechanism includes an arched frame fixedly installed on the top of the base and a rectangular frame disposed inside the arched frame. A mounting base is fixedly installed inside the rectangular frame. A transparent electrode guide cavity is opened inside the mounting base. A threaded interface is fixedly installed on the outside of the transparent electrode guide cavity and on the right side of the mounting base. A transparent electrode guide groove is fixedly installed on the left side of the mounting base. The transparent electrode guide cavity is located inside the transparent electrode guide groove. An adjusting pressure plate is provided on the top of the transparent electrode guide groove.

[0006] As a preferred embodiment of this utility model, a limiting cavity is formed at the top of the left side of the mounting base, and a limiting seat is slidably connected inside the limiting cavity. The left side of the limiting seat is fixedly connected to the adjusting pressure plate.

[0007] In a preferred embodiment of this utility model, a threaded cylinder is fixedly installed inside the limiting cavity, and a threaded rod is rotatably connected inside the limiting seat via a bearing, with the bottom of the threaded rod threadedly connected to the inside of the threaded cylinder.

[0008] As a preferred embodiment of this utility model, a first electric push rod is fixedly installed on the top of the arched frame, and the output shaft of the first electric push rod passes through the arched frame and is fixedly connected to the top of the rectangular frame.

[0009] As a preferred embodiment of this utility model, the top of the base has two guide grooves, and two guide wheels are tactilely connected inside each guide groove. The top of the guide wheels is fixedly connected to the bottom of the placement plate.

[0010] As a preferred embodiment of this utility model, a second electric push rod is fixedly installed on the right side of the mounting block, and the output shaft of the second electric push rod passes through the mounting block and is fixedly connected to the placement plate.

[0011] As a preferred embodiment of this utility model, both sides of the placement plate are provided with receiving grooves, and an installation rod is inserted into the inside of the receiving groove. A spring is sleeved on the outside of the installation rod and inside the receiving groove, and one side of the spring is fixedly connected to the mounting frame.

[0012] As a preferred embodiment of this utility model, two limiting grooves are provided on the front and rear sides of the placement plate, and a limiting rod is inserted into the inside of the limiting groove. One side of the limiting rod is fixedly connected to the mounting bracket.

[0013] This utility model has the following beneficial effects: 1. The equipment achieves thickness adjustment through the collaborative structure of "threaded rod + threaded cylinder + adjusting pressure plate": When the threaded rod is rotated, the limiting seat slides along the limiting cavity, driving the adjusting pressure plate to rise and fall, accurately changing the gap height of the transparent electrode guide groove outlet, which is fully adapted to the "conductivity and thickness correlation" requirements of different electronic devices, compared with traditional manual coating or fixed mold coating.

[0014] 2. The transparent electrode guide trough and guide cavity are made of transparent material, allowing real-time observation of gap changes during adjustment and avoiding blind adjustment. At the same time, the adjusting pressure plate is limited by the sliding limit seat and the limit cavity to ensure no deviation during lifting and lowering, and uniform gap at the outlet of the guide trough, which significantly improves the stability of large-scale production and reduces the difficulty of quality control.

The mounting base 304 is used to install the transparent electrode guide groove 305 and to open the transparent electrode guide cavity 306. The threaded interface is used to connect to the melting equipment of the thermosetting conductive electrode, so as to facilitate the subsequent delivery of the molten conductive electrode into the interior of the transparent electrode guide groove 305 for subsequent coating. The adjusting plate 308 is used to adjust the volume of the inner cavity of the transparent electrode guide groove 305, thereby adjusting the thickness of the subsequently coated conductive electrode to meet the power requirements of different thicknesses.

[0022] A limiting cavity 311 is provided on the top left side of the mounting base 304. A limiting seat 310 is slidably connected inside the limiting cavity 311.

Under the adjustment of the adjusting plate 308, the volume of the transparent electrode guide groove 305 is adjusted, thereby controlling the thickness of the discharged thermosetting conductive electrode to meet different specification requirements.

[0024] A first electric push rod 302 is fixedly installed on the top of the arched frame 301. The output shaft of the first electric push rod 302 passes through the arched frame 301 and is fixedly connected to the top of the rectangular frame 303. The first electric push rod 302 is used to drive the rectangular frame 303 to rise and fall, thereby driving the transparent electrode guide groove 305 to rise and fall to achieve electrode coating on electronic devices.

[0025] The top of the base 1 has two guide grooves 4, and two guide wheels 10 are rolled inside each guide groove 4. The top of the guide wheels 10 is fixedly connected to the bottom of the placement plate 2.

[0026] A second electric push rod 6 is fixedly installed on the right side of the mounting block 5. The output shaft of the second electric push rod 6 passes through the mounting block 5 and is fixedly connected to the placement plate 2. The second electric push rod 6 is set to drive the placement plate 2 to move, thereby moving the placement plate 2 and the electronic device to facilitate subsequent electrode coating.

[0027] Both sides of the placement plate 2 are provided with receiving grooves 11. A mounting rod 16 is inserted into the receiving groove 11. A spring 15 is sleeved on the outside of the mounting rod 16 and inside the receiving groove 11. One side of the spring 15 is fixedly connected to the mounting frame 9. The receiving groove 11 is provided to accommodate the mounting rod 16 and the spring 15. The spring 15 is used to compress the mounting rod 16, thereby causing the mounting rod 16 to move into the receiving groove 11. This further drives the mounting frame 9 and the compression rod 7 to move towards the center, thereby clamping and fixing the electronic device for subsequent coating.

[0028] Two limiting grooves 12 are provided on the front and rear sides of the placement plate 2. A limiting rod 14 is inserted into the inside of the limiting groove 12. One side of the limiting rod 14 is fixedly connected to the mounting frame 9. The limiting grooves 12 and the limiting rod 14 are provided to limit the mounting frame 9 and increase the stability of the mounting frame 9 when it is moved and used.

[0029] Working principle: 1. Equipment initialization and parameter confirmation The operator first checks the status of each component of the equipment: confirms that the base 1 is placed horizontally, the guide wheel 10 rolls smoothly in the guide groove 4, and the lifting and extension functions of the first electric push rod 302 and the second electric push rod 6 are normal; at the same time, the coating process parameters are determined according to the parameters of the electronic device to be coated, including the outlet gap of the transparent electrode guide groove 305, the moving speed of the placement plate 2, and the lifting height of the first electric push rod 302.

[0030] 2. Connecting auxiliary equipment: Connect the melting equipment for the thermosetting conductive electrode to the transparent electrode guide cavity 306 of the mounting base 304 through the threaded interface, ensuring a sealed connection. Start the melting equipment to heat the thermosetting conductive electrode material to a molten state. After the material reaches a stable fluid state, it is ready to enter the coating process.

[0031] 3. Pre-adjustment of the thickness adjustment mechanism According to the preset coating thickness, adjust the outlet gap of the transparent electrode guide channel 305: The operator rotates the threaded rod 309. Since the bottom of the threaded rod is threadedly connected to the threaded cylinder 307 in the limiting cavity 311, the threaded transmission drives the limiting seat 310 to slide up and down along the limiting cavity 311, thereby pushing the adjusting plate 308 to rise and fall; observe the change of the outlet gap through the transparent guide channel until the gap reaches the preset thickness. During the adjustment process, the sliding cooperation between the limiting cavity and the limiting seat ensures that the adjusting plate does not deviate and ensures the uniformity of the gap.

[0032] 4. Workpiece placement and preliminary positioning The operator places the electronic device to be coated on the top of the placement plate 2, so that the left side of the workpiece is in contact with the barrier plate 8, ensuring that the coating area of ​​the workpiece is aligned with the outlet of the transparent electrode guide groove 305. If the workpiece is small, the insertion position of the extrusion rod 7 in the slot 13 of the mounting bracket 9 can be adjusted so that the extrusion rod is facing the clamping area of ​​the workpiece, thus avoiding damage to the edge of the workpiece or the coating area during clamping.

[0033] 5. Flexible clamping and stability assurance The springs 15 on both sides of the placement plate 2 are in a naturally extended state. The elastic force pushes the mounting rod 16 to move outward of the receiving groove 11, thereby driving the mounting frame 9 and the extrusion rod 7 to move closer to the center of the placement plate. The inner side of the extrusion rod is in contact with the front and rear sides of the workpiece to achieve elastic clamping. At the same time, the mounting frame 9 is connected to the limiting groove 12 of the placement plate 2 through the limiting rod 14. During the clamping process, the mounting frame can only slide back and forth along the limiting groove to ensure accurate clamping position and avoid workpiece displacement that may cause coating deviation.

[0034] After clamping is complete, check the workpiece's fixation: gently push the workpiece; if the workpiece does not loosen, confirm that the clamping is reliable, then prepare to proceed to the coating stage.

[0035] 6. Height calibration of thermosetting transparent conductive electrode coating mechanism The first electric push rod 302 is activated, and its output axis extends and retracts downward, driving the rectangular frame 303 to descend along the inner side of the arched frame 301, thereby pushing the mounting base 304 and the transparent electrode guide groove 305 to descend synchronously; when the outlet of the guide groove contacts the coating surface of the workpiece, the first electric push rod 302 stops moving, completing the coating height calibration, ensuring that the outlet of the guide groove is tightly attached to the surface of the workpiece, without gaps or glue leakage.

[0036] 7. Molten material conveying and workpiece movement coating The conveying pump of the melting equipment is turned on, and the molten thermosetting conductive electrode material enters the transparent electrode guide cavity 306 through the threaded interface. After being guided by the guide cavity, it enters the transparent electrode guide groove 305 and finally flows out evenly from the outlet of the guide groove, covering the coating surface of the workpiece. At the same time, the second electric push rod 6 is started, and its output axis extends and retracts to the left, driving the placement plate 2 to move to the left along the guide groove 4. The guide wheel 10 rolls in the guide groove, reducing the resistance of the placement plate and ensuring that the placement plate moves at a uniform speed.

[0037] During the coating process, the molten material flowing out of the feed trough moves with the placement plate, forming a continuous and uniform conductive electrode coating on the workpiece surface. Since the feed trough outlet gap is preset to the coating thickness and the placement plate moves at a stable speed, the transparent feed trough allows for real-time observation of the material flow. If material flow interruption or overflow occurs, the delivery pump pressure can be adjusted in time to ensure coating continuity.

[0038] 8. Automatic identification and stopping of coating endpoint When the placement plate 2 moves to the preset position, the stroke sensor of the second electric push rod 6 sends a feedback signal to control the second electric push rod to stop extending and retracting, and the placement plate stops moving; at the same time, the conveying pump of the melting equipment is turned off to stop the conveying of molten material, the first electric push rod 302 is started, and the guide trough is driven to rise and reset, so as to avoid the guide trough from sticking to the coating in the curing process, and the single coating operation is completed.

[0039] 9. Safe removal of the workpiece After coating is completed, the operator pulls the mounting bracket 9 to both sides, the mounting bracket compresses the spring 15, and drives the mounting rod 16 to move into the receiving groove 11, the squeezing rod separates from the workpiece, and the clamping is released; then the workpiece is taken out from the placement plate 2 and placed in the curing equipment for thermosetting treatment, so that the conductive electrode coating is cured and formed, and has stable conductive properties.

[0040] 10. Cleaning and resetting of equipment If the same specification of workpieces needs to be produced continuously, the "workpiece placement-clamping-coating" process only needs to be repeated. If the workpiece specification is changed, the outlet gap of the guide groove needs to be readjusted. After production is completed, clean the transparent electrode guide groove 305 and guide cavity 306, reset the first electric push rod 302 and the second electric push rod 6 to the initial position, turn off the power of the equipment, and complete the production process.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
