Description

Technical Field

[0001] This utility model relates to the field of positioning equipment technology, and more specifically, to a corrugated paper gluing positioning device. Background Technology

[0002] As a transducer that converts audio electrical energy into sound energy, the speaker is the terminal component of an audio system, and its performance directly determines the final sound reproduction effect of the entire system. Therefore, in professional acoustic environments such as performance halls, theaters, and large-scale artistic performances, there are extremely high requirements for the quality and reliability of speakers.

[0003] To ensure product quality and meet the needs of different users, speakers typically undergo rigorous drop tests before leaving the factory to assess their impact resistance. During this testing process, to prevent damage from direct impact to the ground, a protective component is usually installed on the bottom of the speaker. This protective component can be a paper or foam base, depending on the testing requirements. When a paper base 1 is used, it typically includes a bottom plate 101 and positioning guards 102 surrounding the bottom plate 101, forming a rectangular cross-section support structure. Please refer to the appendix for details. Figure 1 This type of paper base is typically manufactured by cutting a single piece of corrugated cardboard to obtain the main body, which serves as the base plate, and four folding panels that can be bent upwards around the main body to form the positioning guards. After the bending operation is completed, the outer ends of the folding panels need to be glued to the corresponding parts of the base plate to form a stable three-dimensional structure.

[0004] In the aforementioned existing technologies, when fixing the folding plate to the base plate, after applying adhesive, operators need to manually press the adhesive area between the folding plate and the base plate and wait for 2 to 3 minutes to ensure the adhesive has initially cured. This positioning method, which relies on manual pressing, is not only time-consuming and labor-intensive, but also prone to uneven pressure on the positioning edges around the paper base due to the difficulty in maintaining uniform and stable force applied manually. This can lead to problems such as skewing, unevenness, or poor adhesion of the side plates (i.e., positioning edges). This manufacturing defect directly affects the dimensional accuracy and structural strength of the paper base, ultimately resulting in an unsmooth and loose fit between it and the bottom of the speaker. It may fail to provide effective and uniform protection for the speaker during drop tests, affecting the accuracy and reliability of the test results.

[0005] Therefore, there is an urgent need in this field for a solution that can improve upon the above-mentioned shortcomings and achieve efficient, stable and automated press-bonding. Utility Model Content

[0006] To overcome at least one of the defects in the prior art, this utility model provides a corrugated paper gluing and positioning device that can automatically press the side plate of the paper base to achieve efficient and stable positioning and improve work efficiency.

[0007] The technical solution adopted by this utility model is to provide a corrugated paper gluing and positioning device, including a base, on which four positioning baffles are provided. The four positioning baffles are used to form a rectangular positioning space. At least two positioning baffles distributed at right angles can slide horizontally in the direction of approaching and moving away from the positioning space. Each sliding positioning baffle is provided with an elastic reset member between itself and the base, so that the corresponding positioning baffle always has a tendency to move towards the side of the positioning space.

[0008] Compared with the prior art, the corrugated paper gluing and positioning device of this utility model has the following advantages: This utility model relates to a corrugated paper gluing and positioning device, which is a dedicated range-limiting device. It is mainly used to press and limit the side panels of rectangular paper positioning bases during bonding, ensuring that the side panels remain perpendicular and flat to the base plate after gluing. Specifically, four positioning baffles are set on the base to form a rectangular positioning space for placing the paper base to be bonded and pressed. In use, the horizontally movable positioning baffles are first moved outwards, then the paper base with the four side panels folded is placed into the positioning space. The force acting on the sliding positioning baffles is released, and under the action of the elastic reset element, the corresponding positioning baffles move towards the positioning space. The center of the plate automatically resets and moves until it presses firmly against the side plate of the paper base, achieving automatic pressing. Simultaneously, with the assistance of the fixed positioning baffles, the four positioning baffles of the paper base are perpendicular to the base plate, and the free end of the folded plate remains pressed against the base plate, achieving accurate positioning of the bonding position. After the adhesive cures, the sliding positioning baffles are pulled outward again, and the paper base can be removed from the positioning space. The entire process achieves automatic pressing and positioning of the side plate of the paper base and the base plate, replacing the existing manual pressing, ensuring balanced and uniform pressing force, freeing up labor, and improving work efficiency.

[0009] Furthermore, the positioning baffle includes two fixed baffles distributed at right angles, a first sliding baffle and a second sliding baffle distributed at right angles; the base is provided with guide grooves for the first sliding baffle and the second sliding baffle to slide and engage respectively.

[0010] In a further step, the base comprises a mounting base plate, the guiding sliding grooves are formed on the mounting base plate, the lower end surface of the mounting base plate is provided with positioning convex strips respectively corresponding to each of the guiding sliding grooves, each positioning convex strip is provided with a positioning sliding groove which extends along the length direction thereof and has a convex-shaped cross-section at a side close to the mounting base plate, positioning bolts are connected to both the first sliding baffle and the second sliding baffle, and the bolt heads of the positioning bolts respectively pass through the corresponding guiding sliding grooves and are slidably fitted in the positioning sliding grooves.

[0011] As an improvement, avoiding grooves extending along the sliding direction of the sliding baffles are respectively provided on two sides of the two guiding sliding grooves on the mounting base plate, two first connecting plates respectively passing through the avoiding grooves are provided on both the first sliding baffle and the second sliding baffle, second connecting plates respectively disposed opposite to each of the first connecting plates are provided on the lower end surface of the mounting base plate, and an elastic reset member is connected between each of the first connecting plates and the corresponding second connecting plate.

[0012] In a further improvement, the elastic reset member is a tension spring, both ends of the tension spring are provided with pull hooks, and mounting holes for respectively connecting the pull hooks are provided on the first connecting plate and the second connecting plate.

[0013] In a further improvement, four support columns are connected to the lower end of the mounting base plate, and a roller with a brake is connected to the lower end of each support column.

[0014] Other improved features and advantages of the present utility model will be set forth in the following detailed description, and partially will become apparent from the specification, or be understood through implementing the present utility model. The objectives and other advantages of the present utility model can be achieved and obtained through the structures particularly pointed out in the specification and the accompanying drawings.
