Description

Technical Field

[0001] This utility model relates to an adjustable silver paste feeding mechanism, belonging to the field of silver paste feeding technology. Background Technology

[0002] The silver paste supply system is a precision micro-volume delivery system for conductive silver paste. Through quantitative pressurization, stable extrusion, and constant temperature control, it stably, uniformly, and continuously delivers high-viscosity silver paste to coating, dispensing, and printing stations. The system can precisely control the supply pressure, flow rate, and dispensing volume to prevent silver paste sedimentation, bubbles, material interruption, and leakage, ensuring consistent coating thickness and stable conductivity. It is widely used in precision manufacturing fields such as electronic packaging, photovoltaic electrodes, and precision conductive circuit printing.

[0003] Existing silver paste feeding devices suffer from poor positioning accuracy and slow response speed during actual operation. The feeding station cannot be quickly and accurately aligned, which can easily lead to problems such as glue displacement and unstable feeding volume, seriously affecting the coating and printing accuracy. At the same time, the silver paste storage tank has a bulky overall structure, is cumbersome to disassemble and assemble, and lacks a quick docking and positioning structure. Replacing the tank and adding material are complicated operations, and the installation and alignment take a long time. This not only reduces the production efficiency of the equipment, but also affects the continuity of silver paste feeding and the stability of conductive paste supply, which is not conducive to automated continuous production operations.

[0024] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0025] like Figure 1-6 As shown, the adjustable silver paste feeding mechanism includes a mounting frame 11, a translation component, and a lifting component. The translation component is movably mounted on the side wall of the mounting frame 11, and the lifting component is movably connected to the surface of the translation component. A silver paste storage tank 243 is detachably mounted on the translation component. Thus, the translation component drives the storage tank 243 to move, thereby realizing the fixed-point feeding of silver paste. The lifting component is used to squeeze the storage tank 243 to realize the fixed-point and quantitative feeding of silver paste.

[0026] The side walls of the mounting bracket 11 are fixedly connected to the rack 111 and the transverse guide rail 112 respectively. The rack 111 is located below the transverse guide rail 112. A wire bracket 113 is fixedly connected to the top of the mounting bracket 11, and the bottom of the mounting bracket 11 is fixedly connected to the metal plate 114. In this way, the wire bracket 113 is set for the wiring of electrical equipment on the translation component, and can extend and retract as the translation component moves to ensure stable movement.

[0027] The translation assembly includes a side frame 21 and a partition 22. A transverse slide 211 is fixedly installed on one side of the side frame 21, and the transverse slide 211 slides in contact with the surface of the transverse guide rail 112. The partition 22 is fixedly connected to the other side of the side frame 21. A stepper motor 25 is fixedly installed on the side frame 21 on one side of the partition 22. The output ring of the stepper motor 25 is fixedly connected to a gear 251, and the gear 251 meshes with a rack 111. Thus, the stepper motor 25 drives the gear 251 to rotate, and the cooperation between the gear 251 and the rack 111 causes the side frame 21 to move on the mounting frame 11. The cooperation between the transverse guide rail 112 and the transverse slide 211 realizes the stable translation of the side frame 21.

[0028] A drive mechanism is fixedly installed on the surface of the side frame 21. The drive mechanism is connected to the lifting assembly and can drive the lifting assembly to move vertically on the side frame 21.

[0029] The drive mechanism includes a servo motor 221 and two fixed blocks 222. The servo motor 221 and the fixed blocks 222 are respectively located on both sides of the partition 22. The servo motor 221 is fixedly connected to the surface of the side frame 21, and the fixed blocks 222 are fixedly connected to the side wall of the partition 22. The two fixed blocks 222 are located at the upper and lower ends of the partition 22 respectively. A lead screw 223 is rotatably connected inside the fixed blocks 222. The top end of the lead screw 223 and the output end of the servo motor 221 are both fixedly connected to pulleys 224. The pulleys 224 are connected by a belt 225. Thus, when the servo motor 221 works, the lead screw 223 rotates inside the two fixed blocks 222 through the transmission of the belt 225 and the pulleys 224.

[0030] The lead screw 223 is connected to the lifting assembly for transmission. Optionally, the pulley 224 and belt 225 are preferably toothed pulley 224 and toothed belt 225, which can ensure that slippage will not occur during transmission.

[0031] The side frame 21 is fixedly mounted with a longitudinal guide rail 212, and both the longitudinal guide rail 212 and the transverse guide rail 112 have a T-shaped cross-section.

[0032] The bottom of the side frame 21 is fixedly connected to an installation mechanism, which is fixedly connected to the side wall of the partition 22.

[0033] The lifting assembly includes a side plate 23 and a pressing mechanism. The pressing mechanism is fixed to the surface of the side plate 23, and the mounting mechanism is correspondingly arranged below the pressing mechanism. A longitudinal sliding sleeve 231 is fixedly installed on one side of the side plate 23. The longitudinal sliding sleeve 231 slides in contact with the surface of the longitudinal guide rail 212. The surface of the side plate 23 is fixedly connected to a threaded slider 232, and the threaded slider 232 is threadedly connected to the surface of the lead screw 223. Thus, when the lead screw 223 rotates, the side plate 23 can be moved vertically through the threaded slider 232. The cooperation between the longitudinal guide rail 212 and the longitudinal slider can ensure the stable lifting and lowering of the side plate 23.

[0034] The extrusion mechanism includes a guide seat 233, a connecting rod 234, and a pressure head 235. The guide seat 233 is fixedly connected to the surface of the side plate 23. The guide seat 233 is fixedly connected to the pressure head 235 through the connecting rod 234. The pressure head 235 is located above the installation mechanism.

[0035] The installation mechanism includes a base plate 24 and a can sleeve 242. The base plate 24 is fixedly connected to the bottom of the side frame 21 and the partition plate 22 respectively. A semi-circular groove is provided on the base plate 24. The can sleeve 242 is fitted and snapped into the semi-circular groove on the base plate 24. A groove is provided on the surface of the can sleeve 242 to fit into the base plate 24. In this way, when the can sleeve 242 is fitted onto the base plate 24, the groove will prevent the can sleeve 242 from falling off, thus achieving stable support for the can sleeve 242.

[0036] The bottom plate 24 is threadedly connected to a knob 241 on its side. The knob 241 contacts the surface of the can sleeve 242. When the can sleeve 242 is installed in place, the knob 241 is tightened to limit the can sleeve 242, thereby achieving stable fixation of the can sleeve 242.

[0037] The storage tank 243 is fitted inside the tank sleeve 242. The bottom end of the storage tank 243 has a through hole for feeding silver paste. A sealing ring 244 is sealed inside the storage tank 243. The sealing ring 244 is distributed correspondingly to the pressure head 235. When the pressure head 235 moves downward, it contacts the sealing ring 244 and squeezes the silver paste in the storage tank 243 through the sealing ring 244, so that the gel-like silver paste is discharged from the through hole at the bottom, thereby realizing the feeding of silver paste.

[0038] A stop bar 245 is fitted into the bottom of the can sleeve 242. The stop bar 245 is located on one side of the can sleeve 242. Thus, when the can sleeve 242 is not installed, the stop bar 245 is horizontally positioned below the base plate 24. The can sleeve 242 can only be installed by removing the stop bar 245.

[0039] Optionally, the controller of the servo motor 221 is electrically connected to the display screen of the feeding system via a microcontroller. The working interval of the servo motor 221 is used to determine the downward movement distance of the lifting component, and the working status of the servo motor 221 is fed back to the display screen of the feeding system via the microcontroller. When the servo motor 221 works to drive the lifting component to squeeze the silver paste in the storage tank 243, and the silver paste is about to run out, the display screen triggers a prompt to remind the operator to perform a tank replacement operation.

[0040] A cover 26 is fixedly installed on the side frame 21. The bottom of the cover 26 is fixedly connected to the bottom plate 24. A notch is opened at the bottom of the cover 26, which is distributed correspondingly to the storage tank 243. The cover 26 can protect the components of the feeding mechanism.

[0041] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
