Description

Technical Field

[0001] The utility model relates to the field of dispensing equipment for conductive silver glue, in particular to a dispensing equipment for conductive silver glue. Background Technique

[0002] Conductive silver glue is a silver powder-containing glue with conductive function. When processing conductive silver glue, it needs to be quantitatively filled into a dispensing syringe to separate the conductive silver glue for easy use.

[0003] The existing dispensing equipment for conductive silver glue generally uses a solenoid valve or pneumatic valve with a valve seat or valve ball built into the equipment as a stop valve. The front and back of the stop valve are connected to a stirring kettle for stirring silver glue through a stainless steel pipe in a chuck joint manner. The stop valve controls the flow of silver glue inside the stainless steel pipe, thereby controlling the interruption or start of the dispensing process.

[0004] However, the existing dispensing equipment for conductive silver glue uses an internal stop valve to control the stop of silver glue. A large amount of glue is easily left on the inside of the silver glue pipeline, at the interface, inside the valve body, on the valve seat, and on the valve ball, and it is difficult to clean it up completely, resulting in high production losses. Moreover, if the residual glue is not cleaned in time, as the placement time increases, the curing agent in the glue will gradually crosslink and cure with the active groups, blocking the pipeline and the valve body. If the valve body and the pipeline are disassembled and cleaned of the residual glue, it is relatively troublesome. Therefore, a dispensing equipment for conductive silver glue is proposed.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] A glue dispensing device for conductive silver glue, as Figures 1 - 4 shown, includes a base 1. An upper feeding component and a glue dispensing component are fixedly connected to the upper end of the base 1. The upper feeding component is located on one side of the glue dispensing component. A silver glue tube 4 is fixedly connected in communication between the upper feeding component and the glue dispensing component. The glue dispensing component includes a vertical plate vertically fixedly connected to the upper end of the base 1. A stop-flow valve component for controlling the on-off inside the silver glue tube 4 and a glue injection component for injecting glue into a dispensing syringe are fixedly connected to the side wall of the vertical plate. The glue injection component is located above the stop-flow valve component. The silver glue tube 4 penetrates through the stop-flow valve component, and one end of the silver glue tube 4 is clamped to the lower end of the stop-flow valve component.

[0024] The upper feeding component stirs the conductive silver glue and controls the flow of the conductive silver glue. The glue dispensing component divides the silver glue inside the upper feeding component into independent dispensing syringes. The upper feeding component and the glue dispensing component are connected in communication by a silver glue tube 4. The device adopts an external design of the stop-flow valve component. The silver glue tube 4 penetrates through the stop-flow valve component. The silver glue in the silver glue tube 4 will not contact the stop-flow valve component. The stop-flow valve component extrudes the outside of the silver glue tube 4 to control the stop flow of the silver glue. Therefore, there will be no residual glue on the stop-flow valve component, reducing the production loss of the conductive silver glue and avoiding the disassembly and assembly of the stop-flow valve component, fundamentally solving the problem of residual glue.

[0025] The stop-flow valve component includes a mounting seat 5 fixedly connected to one side of the support plate 22. One end of the mounting seat 5 is fixedly connected to a control seat 6. A control port 8 is penetrated and opened on the side wall of the control seat 6. The silver glue tube 4 vertically penetrates through the control seat 6. A stop-flow cylinder 7 is fixedly connected to one side of the control seat 6. The output end of the stop-flow cylinder 7 is fixedly connected to a knife gate 9. The knife gate 9 is located inside the control port 8, and the end of the knife gate 9 is in extrusion fit with the silver glue tube 4.

[0026] As Figure 3As shown in the figure, the silver glue tube 4 penetrates through the mounting seat 5 and passes through the control port 8. The output end of the stop-flow air cylinder 7 controls the movement of the knife gate 9. When the knife gate 9 extends forward, it will squeeze the silver glue tube 4, causing the silver glue tube 4 to be deformed under pressure, and the silver glue inside the silver glue tube 4 is cut off. The stop-flow valve assembly has no contact with the silver glue inside the silver glue tube 4, preventing silver glue from remaining on the stop-flow valve assembly, and the silver glue tube 4 is convenient to disassemble and replace from the stop-flow valve assembly.

[0027] The glue injection assembly includes a fixed seat 19, which is fixedly connected to one side of the support plate 22. A glue distribution plate 11 is fixedly connected to the lower end of the fixed seat 19. A joint 10 is clamped on the glue distribution plate 11. One end of the silver glue tube 4 is connected and clamped to the lower end of the joint 10. A sliding seat 13 is slidably connected to one side of the fixed seat 19. A bottom plate 14 for clamping the lower end of the dispensing syringe is fixedly connected to the lower end of the sliding seat 13. A jig tooling 15 for clamping the upper end of the dispensing syringe is fixedly connected to the middle of the sliding seat 13. A top plate 16 is fixedly connected to the upper end of the sliding seat 13.

[0028] As Figures 1 - 2 shown, the upper end of the dispensing syringe is clamped to the jig tooling 15, and the lower end is just clamped to the bottom plate 14. The dispensing syringe is installed on the glue injection assembly. The joint 10 on the glue distribution plate 11 is convenient for disassembly and replacement, making the joint 10 and the silver glue tube 4 easy to replace, and the connection conversion is simple.

[0029] A metering air cylinder 17 is fixedly connected to the upper end of the top plate 16. A push rod 18 is fixedly connected to the output end of the metering air cylinder 17. The push rod 18 is in press-fitting connection with the piston inside the dispensing syringe. A pressing disc oil cylinder 12 (model TN10-30) is fixedly connected to one side of the fixed seat 19. The pressing disc oil cylinder 12 is located between the fixed seat 19 and the sliding seat 13, and the output end of the pressing disc oil cylinder 12 is fixedly connected to the top plate 16.

[0030] As Figures 1 - 2 shown, the pressing disc oil cylinder 12 drives the sliding seat 13 to descend. The push rod 18 at the output end of the metering air cylinder 17 squeezes the piston inside the dispensing syringe. When injecting glue inside the dispensing syringe, the piston squeezes the push rod 18, causing the push rod 18 to rise. A magnetic switch is set on the equipment. When the push rod 18 moves to trigger the magnetic switch, the silver glue is stopped.

[0031] The feeding assembly includes a stirring device 2, which is fixedly connected to the upper end of the base 1. The end of the silver glue tube 4 far from the glue distribution assembly is connected and fixedly communicated with the inside of the stirring device 2.

[0032] As Figure 1 shown, the stirring device 2 keeps the silver glue in a uniform state. The stirring device 2 is internally provided with a pressure feeding structure, so that the silver glue inside the stirring device 2 flows along the silver glue tube 4 to the glue distribution assembly.

[0033] A clamping fixture tooling 15 is provided with a first clamping groove 20, and the upper end of the dispensing syringe is clamped and matched with the first clamping groove 20. A bottom plate 14 is provided with a second clamping groove 21, and the lower end of the dispensing syringe is clamped and matched with the second clamping groove 21.

[0034] As Figure 4 shown, the upper and lower ends of the dispensing syringe are clamped by the first clamping groove 20 and the second clamping groove 21.

[0035] The working principle of a dispensing device for conductive silver paste provided by the present utility model is as follows:

[0036] During use, the dispensing syringe is installed on the clamping fixture tooling 15 and the bottom plate 14. The dispensing button is activated, and the knife gate 9 pressing on the silver paste tube 4 is opened, allowing the silver paste to flow. The pressing plate cylinder operates to connect the dispensing syringe port with the connector 10. The metering cylinder 17 controls the push rod 18 to descend and press against the syringe piston. The silver paste in the stirring device 2 is injected into the dispensing syringe through the silver paste tube 4 and pushes up the syringe piston. After the push rod 18 rises to a certain extent, the knife gate 9 presses down on the silver paste tube 4, and the silver paste in the silver paste tube 4 stops flowing. The dispensing syringe is controlled to retreat to the material taking position, and the dispensing syringe is disconnected from the connector 10. There will be no residual paste on this non-return valve assembly, reducing the production loss of conductive silver paste and avoiding the disassembly and assembly of the non-return valve assembly, fundamentally solving the problem of residual paste.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
