Description

TECHNICAL FIELD

[0001] The utility model belongs to lithium ion battery technical field, concretely relates to a new energy battery box body bottom gumming device. BACKGROUND

[0002] In industrial production, the gluing operation of box body parts is a common and important process link, which is widely used in many fields such as electronic equipment shell, automobile parts, aerospace equipment, etc. The quality and efficiency of gluing directly affect the sealing performance, connection strength and overall production benefit of the product.

[0003] The traditional box body gluing method mainly relies on manual operation. Although manual gluing has certain flexibility, it has many significant drawbacks. First, the gluing quality is unstable, and there are differences in the operation proficiency and experience of different workers, which makes it difficult to maintain consistency in the thickness and uniformity of the glue, and it is easy to cause too much or too little glue, which affects the sealing effect and connection reliability of the product. Second, manual gluing is low in efficiency, and in mass production, manual gluing speed cannot meet the production demand, increasing production cost and production cycle. Moreover, long-term gluing operation can cause workers to feel tired, further reducing the gluing quality and efficiency.

[0004] In order to improve the gluing efficiency and quality, some enterprises begin to use simple mechanical gluing equipment. However, the existing mechanical gluing equipment also has certain limitations. The structure design of some equipment is not reasonable enough, and it cannot adapt to the gluing requirements of box bodies of different specifications and shapes, and the universality is poor. For example, for some special-shaped box bodies or products with special gluing path requirements, the existing equipment is difficult to accurately complete the gluing task. In addition, the existing mechanical gluing equipment is not accurate enough in the positioning and extrusion control of the glue pipe, which can easily cause unstable glue extrusion, affecting the consistency of gluing. Moreover, the automation degree of some equipment is low, and still needs more manual intervention, which cannot realize efficient automatic production.

[0005] In summary, there is a lack of a box body gluing device that can adapt to different box body specifications, has stable gluing quality, high automation degree and reasonable structure in the market. Therefore, it is of great practical significance and market demand to develop a new type of box body gluing device. UTILITY MODEL CONTENTS

[0041] As a preferred technical scheme of the utility model, the servo motor can automatically discharge the front end mixed uneven glue after the glue filling is completed.

[0042] The use method of the device is:

[0043] Firstly, the operator installs the glue pipe of appropriate specification into the glue pipe positioning structure. The glue pipe passes through the positioning slots on the upper positioning plate and the lower positioning plate, and the glue pipe guide rod provides guidance for the installation of the glue pipe, thereby ensuring that the glue pipe is accurately installed in place. Then, the height position of the clamping jaw cylinder on the back plate is adjusted, so that the clamping jaw can accurately clamp the appropriate part of the glue pipe. Subsequently, the entire device is installed on the end of the industrial robot through the flange plate, and the industrial robot is programmed according to the shape, size and gluing requirement of the to-be-glued box body, and the gluing path and speed parameters are set.

[0044] When the device is started, the industrial robot moves the entire gluing device to the starting position of the to-be-glued box body according to the pre-set program. At this time, the driving mechanism starts to work, the servo motor is powered on and started, and the output shaft drives the lead screw to rotate through the shaft coupling. Due to the cooperation between the nut and the lead screw, the rotation of the lead screw will make the nut move linearly along the lead screw, and the nut is connected with the extrusion plate, thereby driving the extrusion plate to move synchronously. The symmetrically arranged extrusion rods and extrusion heads on the extrusion plate also move, and the extrusion heads exert extrusion force on the glue pipe, so that the glue in the glue pipe is extruded out.

[0045] During the movement of the extrusion plate, the guide shaft plays a guiding role on the extrusion plate, ensuring that the extrusion plate moves stably and linearly, avoiding the deviation of the extrusion plate, and thereby ensuring the stability of the glue extrusion amount. At the same time, the U-shaped sensor monitors the position of the extrusion plate in real time, and when the extrusion plate moves to a specific position, the U-shaped sensor sends a signal, and the control system controls the action of the servo motor according to the signal, so as to realize the accurate control of the glue extrusion amount and the gluing process.

[0046] At the same time of extruding the glue, the industrial robot moves according to the set path and speed, drives the gluing device to perform gluing work along the gluing part of the box body, and ensures that the glue is evenly applied on the surface of the box body.

[0047] When the glue in the glue pipe is used up and the glue pipe needs to be replaced, the clamping jaw cylinder acts, the piston rod retracts, and the clamping jaw releases the glue pipe that has run out of glue. The operator takes out the empty glue pipe, installs a new glue pipe into the glue pipe positioning structure, and the clamping jaw cylinder acts again, the piston rod extends, so that the clamping jaw clamps the new glue pipe again, and then the device continues the gluing work.

[0048] In summary, the box gluing device realizes efficient, stable and high-quality box gluing operation through the accurate control of the industrial robot, the precise adjustment of the glue extrusion amount of the driving mechanism and the cooperation between the components.

[0049] For those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of protection of the present application.
