Technical Field

[0001] The invention relates to the field of glue coating equipment, in particular to a quantitative machine used in a glue coating system. Background Art

[0002] Under the existing technology, the gluing process of photovoltaic module manufacturing equipment basically adopts the PCF gluing system. The key component of this gluing system, the contact flow meter, is an imported device, which has the disadvantages of high price, limited glue supply distance, measurement accuracy will decrease with use due to gear wear, and output pressure is affected by glue supply pressure.

[0003] Therefore, a dosing machine for a glue coating system is needed, which can meet the requirements of continuously maintaining the metering accuracy of the dosing machine and stabilizing the output pressure under a preset glue supply distance, and can also control the cost of the dosing machine downward, which is conducive to the promotion and application of glue coating equipment. Summary of the invention

[0004] In view of this, the purpose of the present invention is to overcome the defects in the prior art and provide a dosing machine for a glue coating system, which can meet the continuous maintenance of the metering accuracy of the dosing machine and the stable maintenance of the output pressure under a preset glue supply distance, and can also control the cost of the dosing machine downward, which is conducive to the promotion and application of glue coating equipment.

[0005] The quantitative machine for the glue coating system of the present invention comprises a coating cylinder and a power assembly, wherein the power assembly comprises a thrust cylinder and a thrust piston, wherein the thrust cylinder has a chamber I and a chamber II, and the thrust piston has a power rod, a piston I and a piston II;

[0006] The piston I and the piston II are coaxially arranged on the power rod, the piston I is driven by the power rod to make a reciprocating motion in the chamber I, and the piston II is driven by the power rod to make a reciprocating motion in the chamber II;

[0007] The power rod is also coaxially connected to the piston rod of the paint cylinder;

[0008] It also includes a stroke monitoring element, which is used to monitor the movement stroke of the power rod.

[0009] Furthermore, it also includes a support frame arranged between the paint cylinder and the thrust cylinder, and the support frame fixedly connects the paint cylinder and the thrust cylinder.

[0010] Furthermore, it also includes an inlet valve arranged at the feed port of the paint tank, and the inlet valve is controlled to open and close.

[0011] Furthermore, the middle part of the thrust cylinder in the height direction is partitioned by a partition plate to form chamber I and chamber II, and the power rod passes through the center of the partition plate to connect piston I and piston II, so that chambers I and chambers II of the thrust cylinder are stacked in the vertical direction.

[0012] Furthermore, the piston I is arranged at the top of the power rod, the piston II is arranged at the middle of the power rod, and the bottom end of the power rod is connected to the piston rod of the paint cylinder, so that the piston rod of the paint cylinder drives piston I and piston II to move up and down at the same time.

[0013] Furthermore, the stroke monitoring element is a displacement sensor, the measuring end of the displacement sensor extends into the thrust cylinder and is connected to the piston I, the housing of the displacement sensor is arranged on the outside of the thrust cylinder, and the connection between the housing of the displacement sensor and the thrust cylinder is sealed.

[0014] Furthermore, the central axis of the displacement sensor is coaxially arranged with the power rod so that the measuring end of the displacement sensor is located at the center of the piston I.

[0015] The displacement sensor is a non-contact magnetostrictive displacement sensor, which uses internal non-contact measurement and control technology to accurately detect the absolute position of the movable magnetic ring to measure the actual displacement value of the detected product.

[0016] Furthermore, the volumes of chamber I and chamber II are the same, and the height of the position of piston I in chamber I is consistent with the height of the position of piston II in chamber II.

[0017] In view of the deficiencies in the prior art, the present invention forms a multi-cylinder series structure through chamber I and chamber II connected in series by a thrust cylinder, so that the glue supply pressure can be stabilized, and the non-contact quantitative control of the magnetostrictive displacement sensor is used to ensure the glue discharge accuracy, and the metering is more accurate. An inlet valve is added to ensure that the glue supply pressure does not affect the output pressure, thereby increasing the glue supply distance, improving the stability of the metering accuracy and the stability of the output pressure, and at the same time, due to its simple structure, it has better maintainability and cost-effectiveness. The present invention also has the advantages of high output pressure, high metering accuracy and good stability, simple structure, compact appearance, easy installation and long service life.

[0018] In the present invention, chamber I and piston I form an upper cylinder, chamber II and piston II form a lower cylinder, and the upper cylinder and the lower cylinder are connected in series as a whole through a power rod. Air is simultaneously introduced into the upper cylinder and the lower cylinder so that they act on the paint cylinder at the same time, thereby forming a double driving force to push the piston rod of the paint cylinder, so that the medium in the paint cylinder can be pushed out with precise control, and the driving stroke of the paint cylinder piston rod is controlled by a magnetostrictive displacement sensor, thereby realizing quantitative, precise and stable output of the medium.

[0019] This solution also has the following advantages:

[0020] 1) The upper cylinder and the lower cylinder are connected in series through the power rod, which can output double thrust, thereby increasing the glue supply distance.

[0021] 2) The quantitative output control of the medium in the paint tank is achieved through a non-contact magnetostrictive displacement sensor. The two are not in direct contact, which extends the service life of the displacement sensor.

[0022] 3) The upper cylinder and the lower cylinder act on the piston rod of the paint cylinder at the same time. When the piston rod of the paint cylinder pushes out the medium in the paint cylinder, the inlet valve is in the closed state, so that the pressure of the glue supply does not affect the output pressure of the dosing machine, thereby improving the stability of the output pressure.

[0023] 4) The overall structure adopts a split structure, connecting the paint cylinder and the thrust cylinder through a support frame, which is simple and convenient to maintain and has stronger versatility.

[0024] The beneficial effects of the present invention are as follows: the quantitative machine for a glue coating system disclosed by the present invention increases the glue supply distance, improves the stability of metering accuracy and the stability of output pressure through multi-cylinder series connection, non-contact quantitative control, and the addition of an inlet valve to ensure that the glue supply pressure does not affect the output pressure. At the same time, due to its simple structure, it has better maintainability and cost-effectiveness. BRIEF DESCRIPTION OF THE DRAWINGS

The chamber Ⅰ1 and the chamber Ⅱ3 are independent of each other. The power rod 4 passes through the center of the partition plate 11 to connect the piston Ⅰ12 and the piston Ⅱ13, so that the chamber Ⅰ1 and the chamber Ⅱ3 of the thrust cylinder 9 are stacked in the vertical direction; so that the power rod 4 is more convenient to drive and has better control stability;

[0032] The space utilization rate is the highest, and the momentum of the thrust cylinder 9 is easier to calculate, which is conducive to more accurate and reliable determination of the glue output of the paint cylinder 6, and the glue supply distance can be relatively extended.

[0033] The power rod 4 is also coaxially connected to the piston rod 5 of the paint cylinder 6; the power stability and the accuracy of determining the discharge amount are better.

[0034] It also includes a stroke monitoring element, which is used to monitor the movement stroke of the power rod 4; the stroke monitoring element is a displacement sensor 2, the measuring end of the displacement sensor 2 extends into the thrust cylinder 9 and is connected to the piston Ⅰ12, the housing of the displacement sensor 2 is arranged on the outside of the thrust cylinder 9, and the connection between the housing of the displacement sensor 2 and the thrust cylinder 9 is sealed; the central axis of the displacement sensor 2 is coaxially arranged with the power rod 4 so that the measuring end of the displacement sensor is located at the center of the piston Ⅰ12. More specifically, the displacement sensor 2 is any non-contact magnetostrictive displacement sensor 2 in the prior art. It is used in this solution, and the absolute position of the active magnetic ring is accurately detected by the internal non-contact measurement and control technology to measure the actual displacement value of the detected product, which will not be repeated here.

[0035] In this embodiment, a support frame 10 is further included, which is arranged between the paint cylinder 6 and the thrust cylinder 9, and the support frame 10 fixedly connects the paint cylinder 6 and the thrust cylinder 9. The support frame 10 described in this solution is columnar, and the paint cylinder 6 and the thrust cylinder 9 are connected to form a whole in a disassembled and separable manner by bolt locking, which is conducive to ensuring the centrifugal property of the power rod 4 and the piston rod 5, meeting the stability of the motion stroke, and improving the glue discharging accuracy of the paint cylinder 6.

[0036] In this embodiment, an inlet valve 7 is also provided at the feed port of the paint tank 6, and the inlet valve 7 is controlled to open and close. The inlet valve 7 can be provided to ensure the stability of the glue discharge pressure, so that the glue discharge accuracy is guaranteed and the measurement is more accurate; the inlet valve 7 can be selected from any one of the existing technologies to meet the corresponding opening and closing functions, which will not be described in detail here. The paint tank discharge port 8 is connected to an external glue coating device to meet the glue application function at a designated position.
