Description

Technical Field

[0001] The utility model relates to the technical field of flow control, in particular to a colloid pressure-stabilizing conveying component and a glue spraying device. Background Art

[0002] In the process of processing or assembling parts in industries such as automotive parts and photovoltaic components, high-concentration colloids are often used for fixation. In this process, the coating and infusion of the colloid are mostly achieved through gluing equipment. For example, the colloid in the glue barrel is transported to the glue discharge head by a plunger pump, and the operator adjusts the position of the glue discharge head so that the high-concentration colloid can be transported to the part to be coated.

[0003] However, high-concentration colloids are more likely to solidify quickly and have poor stability. Therefore, during the transportation process, high-concentration colloids may partially solidify or stratify in the transportation pipeline, changing their flow characteristics, thereby causing changes in the pressure value of the high-concentration colloid at the glue discharge head. Changes in pressure values ​​can easily make it difficult to control the amount of glue discharged from the glue discharge head, thereby affecting the glue coating accuracy.

[0004] In addition, when the colloid is transported through some long conveying pipes, due to the friction between the colloid and the conveying pipe, the viscosity and fluidity of the colloid may be affected by temperature changes, which may also cause pressure fluctuations, thereby affecting the glue coating accuracy.

[0005] Therefore, the above problems need to be solved urgently. Utility Model Content

It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] See also Figures 1 to 3 In this embodiment, a glue application device is proposed, which includes a glue barrel 8, a plunger pump 9, a conveying pipe 1, a glue discharge head 10 and a colloid pressure-stabilizing conveying component; the two ends of the conveying pipe 1 are respectively connected to the output port of the plunger pump 9 and the glue discharge head 10, and the plunger pump 9 is used to convey the colloid in the glue barrel 8 to the glue discharge head 10 through the conveying pipe 1, and the colloid pressure-stabilizing conveying component can be connected in series to the conveying pipe 1 for conveying the colloid to stably convey the colloid, that is, the colloid pressure-stabilizing conveying component can keep the pressure value of the colloid at the glue discharge head 10 at a preset pressure value, so as to ensure that the colloid can be stably conveyed in the conveying pipe 1, thereby ensuring the pressure stability at the glue discharge head 10, and then improving the glue coating accuracy.

[0038] Specifically, along the conveying direction of the colloid, the colloid pressure-stabilizing conveying assembly includes an energy storage tank 2, a flow meter 3, a proportional flow control valve 4 and a pressure regulating valve 5 which are sequentially arranged in series.

[0039] Among them, the energy storage tank 2 is arranged on the conveying pipeline 1 through the mounting block, and the energy storage tank 2 is connected with the conveying pipeline 1. When the colloid enters the conveying pipeline 1 under the pressure of the plunger pump 9, if the pressure at this time is greater than the pressure in the energy storage tank 2, the colloid will enter the energy storage tank 2, thereby reducing the pressure in the conveying pipeline 1. Conversely, when the pressure at this time is less than the pressure in the energy storage tank 2, the colloid in the energy storage tank 2 will enter the conveying pipeline 1, thereby increasing the pressure in the conveying pipeline 1. Such an arrangement can ensure that the pressure value at the inlet of the conveying pipeline 1 remains stable. In addition, the pressure inside the energy storage tank 2 is preferably consistent with the preset pressure value at the glue outlet.

[0040] The flow meter 3 is electrically connected to the proportional flow control valve 4 so that the flow of the colloid on the downstream side of the proportional flow control valve 4 can be controlled through the proportional flow control valve 4; the flow meter 3 can detect the colloid flow in the delivery pipeline 1 and transmit a signal to the proportional flow control valve 4 so that the proportional flow control valve 4 can accurately control the colloid flow on the downstream side of the proportional flow control valve 4.

[0041] The proportional flow control valve 4 is electrically connected to the pressure regulating valve 5, and the pressure regulating valve 5 is used to keep the colloid on the downstream side of the pressure regulating valve 5 at a preset pressure value. After the colloid passes through the proportional flow control valve 4, the proportional flow control valve 4 can transmit a signal to the pressure regulating valve 5, so that the pressure regulating valve 5 can adjust the pressure value of the colloid on the downstream side of the pressure regulating valve 5. Among them, the preset pressure value is determined according to actual needs, and no excessive restrictions are made here.

[0042] Furthermore, the colloid pressure-stabilizing delivery assembly further includes a first pressure sensor 6 and a second pressure sensor 7, wherein the first pressure sensor 6 is arranged on the upstream side of the pressure regulating valve 5, and the second pressure sensor 6 is arranged on the downstream side of the pressure regulating valve 5. It is understandable that the first pressure sensor 6 can detect the pressure value at the inlet of the pressure regulating valve 5, and the second sensor can detect the pressure value at the outlet of the pressure regulating valve 5, so that the operator can monitor the pressure value inside the pipeline. When the first sensor and the second sensor detect that the pressure value in the delivery pipeline 1 is abnormal, a feedback signal can be sent to the controller electrically connected thereto, and the controller can control the proportional flow control valve 4 to adjust the air pressure of the pressure regulating valve 5 in real time, thereby ensuring that the delivery pipeline 1 can smoothly and stably feed materials.

[0043] The glue spraying device also includes a lifting device 11, and the plunger pump 9 is arranged at the lifting end of the lifting device 11. In practical applications, the plunger pump 9 can make the input port below the liquid level of the colloid under the action of the lifting device 11. When the plunger pump 9 is pumping glue, the colloid enters from the input port and is discharged from the output port.

[0044] In particular, the lifting device 11 includes a plurality of lifting cylinders 111 and a connecting plate 112, the piston rod of each lifting cylinder 111 is connected to the connecting plate 112, and the plunger pump 9 is arranged on the connecting plate 112. In practical applications, the plurality of lifting cylinders 111 are evenly distributed around the rubber barrel 8, the connecting plate 112 is arranged above the rubber barrel 8, and the plunger pump 9 is directly opposite to the rubber barrel 8, so that under the action of the lifting cylinder 111, the plunger pump 9 can be driven to approach or move away from the colloid.

[0045] Furthermore, the glue-spraying device further includes a mounting seat 12 and a glue pressing plate 13, wherein the mounting seat 12 is arranged on the plunger pump 9, and the glue pressing plate 13 is detachably arranged on the mounting seat 12, and the glue pressing plate 13 is adapted to the inner peripheral wall of the glue barrel 8. In practical applications, different types of glue pressing plates 13 can be selected according to actual working conditions, so as to ensure that the glue pressing plate 13 can seal the colloid during the conveying process, thereby preventing external air from entering the conveying pipeline 1. In addition, the glue pressing plate 13 can be arranged on the mounting seat 12 by a detachable connection structure such as a snap connection or a buckle connection.

[0046] The glue-spraying device further includes a seal 14, which is disposed between the inner peripheral wall of the glue barrel 8 and the glue pressing plate 13. This arrangement can further ensure the sealing effect of the glue, thereby further preventing external air from entering the conveying pipeline 1. The seal 14 is preferably a sealing ring.

[0047] In actual applications, since the overall weight of the glue barrel 8 is relatively heavy when fully loaded, it is inconvenient for workers to move the glue barrel 8 when adjusting the position between the glue barrel 8 and the plunger pump 9. For this reason, in this embodiment, the glue application equipment also includes a roller frame 15, a plurality of rollers 16 and a plurality of locking members. The roller frame 15 is arranged below the plunger pump 9; the plurality of rollers 16 are evenly arranged on the roller frame 15, and any roller 16 can rotate around its own axis; the locking members are arranged one-to-one with the rollers 16, and the locking members are used to limit the rotation of the rollers 16. In actual applications, the glue barrel 8 is placed on the roller 16, and the position of the glue barrel 8 can be adjusted by relying on the rolling friction between the roller 16 and the glue barrel 8. After the adjustment is completed, the roller 16 is locked by the corresponding locking member, so as to prevent the glue barrel 8 from moving when the colloid is transported. Among them, the locking member is preferably a pin.

[0048] Further, a proximity switch is provided on the roller frame 15 so that the glue barrel 8 can be directly opposite to the plunger pump 9. This arrangement is provided so as to provide feedback to the worker on the information that the glue barrel 8 has moved into position.

[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
