Technical Field

[0001] The utility model relates to the technical field of silver paste filling, in particular to an integrated silver paste filling device. Background Art

[0002] In the process of manufacturing solar panels, silver paste needs to be printed on the positive field and aluminum paste needs to be printed on the back field. Screen printing has the characteristics of low cost and stable technology and is widely used in the printing of positive and negative poles of solar panels. Silver paste is a viscous paste composed of a mechanical mixture of high-purity metallic silver particles, adhesives, solvents, and additives. It is a paste for making silver electrodes.

[0003] In the past, before using silver paste for screen printing, the original paste tank had to be manually refilled into a specific pressure tank. The refilled silver paste pressure tank was then poured again by a specific pouring device before it could be poured into the filling glue barrel. Finally, the grouting machine could fill the equipment for use.

[0004] The existing integrated silver paste filling machine uses the raw material barrel to feed the material. After the raw material barrel is installed, the entire vacuum feeding box needs to be evacuated to reduce the residual air in the system pipeline when the raw material barrel is fed. However, the volume of the vacuum box is large, and there are several problems with vacuuming:

[0005] 1. The vacuuming time is long and the waiting time is long, resulting in a waste of production time;

[0006] 2. The vacuum degree is not high enough and there is a lot of residual air. Utility Model Content

The integrated silver paste filling equipment of the utility model directly uses the raw material barrel of the silver paste for loading, which reduces the intermediate filling links, reduces labor costs, and also reduces the loss that may be generated during the process of pouring the paste into the special syringe. At the same time, it can reduce the vacuum volume to reduce the amount of air in the pipeline and reduce the impact on the subsequent screen printing.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1-4 As shown, the integrated silver paste filling equipment of the utility model includes: a support frame 1, a filling drive power source 2, a lifting slide 3, a positioning mounting plate 4, a vacuum barrel sleeve 5, an inflatable sealing ring 6, a raw material barrel 7 and a piston 8; the filling drive power source 2 is installed on the support frame 1, and the filling drive power source 2 is used to provide power when the silver paste is filled; the lifting slide 3 is connected to the filling drive power source 2; the positioning mounting plate 4 is fixedly connected to the lifting slide 3; the vacuum barrel sleeve 5, the upper end of which is installed on the positioning mounting plate 4 On, an inflatable sealing ring 6 is provided between the vacuum barrel sleeve 5 and the positioning mounting plate 4, and the inflatable sealing ring 6 seals between the vacuum barrel sleeve 5 and the positioning mounting plate 4 when inflated, so that a vacuum structure is formed in the vacuum barrel sleeve 5; a raw material barrel 7, which is arranged in the vacuum barrel sleeve 5, and silver paste is arranged in the raw material barrel 7; a piston 8, which is arranged in the raw material barrel 7, and a center hole 81 is provided on the piston 8, and the center hole 81 is connected with the raw material barrel 7, and the silver paste in the raw material barrel 7 is discharged through the center hole 81 to realize feeding.

[0028] Preferably, the filling drive power source 2 is a cylinder.

[0029] In the above structure, the support frame 1 is provided with a linear guide 11, the lifting slide 3 is connected with a slider 31, and the slider 31 is slidably connected to the linear guide 11. The linear guide 11 is arranged along the driving direction of the filling driving power source 2. The linear guide 11 is used as a guide and the cylinder is used as a power to drive the raw material barrel 7 to move up and down to realize the feeding / replacing function.

[0030] In the above structure, the lower end of the positioning mounting plate 4 is an open structure, and the vacuum barrel sleeve 5 is installed on the inner wall of the positioning mounting plate 4 through the opening. An annular groove 41 is provided on the inner wall of the positioning mounting plate 4, and the inflatable sealing ring 6 is arranged in the annular groove 41.

[0031] In the above structure, the vacuum barrel sleeve 5 and the raw material barrel 7 are cylindrical structures with an open upper end, and the outer diameter of the raw material barrel 7 is smaller than the inner diameter of the vacuum barrel sleeve 5 .

[0032] In the above structure, the inflatable sealing ring 6 is annular, and an inflatable cavity 61 is provided inside the inflatable sealing ring 6. An inflatable joint 62 is provided on the outer wall of the inflatable sealing ring 6, and the inflatable joint 62 is connected to the inflatable cavity 61. The inflatable sealing ring 6 is used to separate the inner and outer spaces of the vacuum barrel sleeve 5. The appearance of the inflatable sealing ring 6 changes greatly before and after inflation, so that the vacuum barrel sleeve 5 can be easily installed and well sealed. Compared with the O-ring, a certain amount of compression is required to form a sealing effect, and manual installation is very laborious, and the O-ring will also be sheared. Therefore, the inflatable sealing ring 6 is preferably used. When the inflatable sealing ring 6 is inflated, the inflatable sealing ring 6 expands to separate the inside and outside of the vacuum barrel sleeve 5.

[0033] In the above structure, the positioning mounting plate 4 is connected to a piston guide sleeve 9, and the piston 8 is arranged in the piston guide sleeve 9. The piston guide sleeve 9 is provided with a vacuum joint 91, and the vacuum joint 91 is connected to the vacuum barrel sleeve 5. The other end of the vacuum joint 91 is connected to a vacuum negative pressure device, so that the vacuum device vacuums the inside of the vacuum barrel sleeve 5 through the vacuum joint 91.

[0034] In the above structure, the piston 8 is connected to a piston connecting rod 10, the support frame 1 is provided with a pneumatic ball valve 12, the axis of the piston connecting rod 10 is provided with a through hole, and the center hole 81 is connected to the pneumatic ball valve 12 through the through hole. The piston 8 is a polyurethane piston with good corrosion resistance and wear resistance. A Y-shaped lip structure is set at the front end of the center hole 81. This Y-shaped lip structure is resistant to high pressure and can also shrink the outer dimensions to adapt to the small characteristics of the raw material barrel.

[0035] The filling drive power source 2 moves upward, pushing the positioning mounting plate 4, the vacuum barrel sleeve 5 moves upward, the piston 8 enters the raw material barrel 7, and the slurry is squeezed out from the center hole 81 of the piston 8, passes through the pneumatic ball valve 12 above, and then enters the input end of the screw valve, so as to achieve the purpose of feeding the screw valve, and then the slurry is accurately output through the screw valve.

[0036] The working principle of the integrated silver paste filling equipment of the utility model is:

[0037] The cylinder is used as a power to push the raw material barrel 7 upward, and the piston 8 squeezes the slurry in the raw material barrel 7 and squeezes the slurry to the inlet of the glue discharge valve to complete the feeding function.

[0038] During the entire feeding process, the raw material barrel 7 (including slurry) is first placed in the vacuum barrel sleeve 5, and then the whole is installed on the positioning mounting plate 4. Then the inflatable seal ring 6 is inflated to form a closed cavity inside the vacuum barrel sleeve 5, and then the vacuum is started. After the vacuum degree reaches the limit for a period of time, the push cylinder below is pneumatically driven to complete the feeding process. Then the glue dispensing valve is driven by a servo motor to accurately dispense glue. The pneumatic valve has the function of pneumatically opening and closing the pipeline during the material change process to prevent the slurry in the pipeline from being sucked back into the raw material barrel.

[0039] The silver paste filling device of the utility model cancels the original vacuum feeding box, and the vacuumed space is only the space inside the vacuum barrel sleeve 5, which greatly reduces the vacuumed space and can reach a higher vacuum degree in a very short time.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
