Description

Technical Field

[0001] This invention relates to the field of adhesive equipment technology, and more specifically to an acoustic foam bonding and fixing device. Background Technology

[0002] Acoustic foam, as a core auxiliary material for achieving sound insulation and noise reduction, cushioning and shock absorption, sealing and dust prevention, and acoustic performance optimization, needs to be precisely fitted to the designated assembly area of ​​the product, which is a key process in the mass production process of related products.

[0003] Currently, most acoustic foam bonding operations in the industry employ a purely manual bonding method. Operators fix the product to be processed on a general workbench, complete the initial positioning of the product by visual alignment or reference line comparison, and manually align the bonding area to complete the bonding. However, the existing technology has significant defects and shortcomings: low operating efficiency, inconvenience in handling hands and foam components during manual operation, resulting in unstable bonding accuracy, easy occurrence of problems such as foam tilting and positional deviation, significantly increasing the product defect rate, and making it difficult to match the capacity requirements of large-scale mass production.

[0004] In summary, traditional acoustic foam bonding technology is no longer adequate to meet the current industry's demands for product bonding accuracy and production capacity efficiency. Therefore, it is necessary to develop an acoustic foam bonding and fixing device that can improve bonding accuracy and efficiency.

[0059] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Please see Figures 1-21 The present invention will describe the above technical solution in detail through the following embodiments:

[0061] This example demonstrates a bonding and fixing device, using the bonding of a smart stylus to an acoustic foam body 6 as an example. The bonding area is equipped with a bonding groove, such as... Figure 9 and Figure 10 The structure shown requires the acoustic foam body 6 to accurately and efficiently complete the processes of picking up, aligning, bonding, and peeling off the equipment in order to meet the needs of stable and reliable assembly line production.

[0062] Specifically, the equipment includes an operating base 1 equipped with start / stop buttons. Before bonding operations, the positioning module 3 and flipping module 4 of the bonding fixing part need to be aligned and adjusted to ensure accurate bonding. In this embodiment, two XYR alignment platforms 5 are installed on the operating base 1 as the mounting base for the positioning module 3 and flipping module 4. The XYR alignment platform 5 is an application of existing products and is a three-axis parallel motion mechanism. Spatial position adjustment is achieved through the parallel movement of linear moving axes. This structure is commonly used in existing pick-and-place machines and will not be explained in detail. Its purpose is to obtain the height difference and position alignment function during bonding, and it is suitable for adjusting different bonding parts of various product specifications, with strong applicability and adjustability.

[0063] like Figures 8-11 As shown in the structure, the positioning module 3 in this embodiment is used to clamp and fix the product to be bonded. Since this embodiment takes a smart stylus as an example, a limiting slot 301 is provided in the middle of the horizontal base plate 31 with a first limiting protrusion 311 and a second limiting protrusion 312 at both ends to support the smart stylus to be bonded. In order to maintain good support and positioning capabilities, a base plate 36 is fixedly installed on the horizontal base plate 31 between the first limiting protrusion 311 and the second limiting protrusion 312. At the same time, a positioning block 35 is installed within the support range of the limiting slot 301. A limiting pad 37 with the same height as the positioning block 35 is provided on the base plate 36.

[0064] The positioning plate 32 is rotatably mounted on the horizontal base plate 31 via the base plate 36, which can hold and fix the smart stylus when closed. In order to facilitate opening and replacement of the smart stylus to be bonded, in this embodiment, locking buckles 33 and locking blocks 34 are respectively installed on the outside of the positioning plate 32 and the base plate 36 for quick locking.

[0065] In this embodiment, to avoid structural interference during the bonding process, such as... Figure 5 As shown in the positional relationship, after the smart stylus is clamped, its height is higher than the second limiting protrusion 312, which can prevent it from colliding with the positioning pin 4610 that fixes the acoustic foam body 6; specifically, in this embodiment, the flip module 4 is as follows Figures 12-15 As shown, the system includes a base plate 41 on which a cover plate 42 is rotatably mounted. To maintain automatic engagement and ensure consistent fit, the cover plate 42 is rotatably mounted on the base plate 41 via a rotating seat 411. A ferromagnetic plate 43 is mounted at the bottom of the cover plate 42. An electromagnet 44 aligned with the ferromagnetic plate 43 is mounted on the base plate 41, along with a horizontal pad 47 that stably supports the cover plate 42 at a consistent horizontal height. Spring posts 48 are mounted on both sides of the horizontal pad 47 to promptly release the cover plate 42 when the power is disconnected, facilitating subsequent repetitive operations. A flipping stop 45 is mounted on the outer side of the base plate 41 to support and flip the cover plate 42. A hand handle 421 is horizontally mounted on the outer edge of the cover plate 42. A magnetic switch is provided on the horizontal pad 47. When the cover plate 42 is closed, the electromagnet 44 is activated and magnetically attracted. When the electromagnet 44 is de-energized, a buzzer sounds a warning.

[0066] like Figure 5 ,like Figures 16-19As shown in the structure, a bonding component 46 is installed on the side of the cover plate 42 near the positioning module 3. Specifically, it includes a first cylinder 461 on the cover plate 42, which is vertically slidably mounted on the lifting frame 463 via a vertical slide rail 466 and a guide slider 467. In order to obtain a buffer protection function to avoid hard contact during bonding, a vertical displacement distance is required. Therefore, in this embodiment, a top plate 462 is installed on the output shaft of the first cylinder 461. The top plate 462 is provided with a horizontal baffle 4621 for embedding in the groove 4631. A reset spring 464 is installed in the groove 4631. When the cover plate 42 is closed, the smart touch pen clip in the fixed position will abut against and compress the reset spring 464, so that the lifting frame 463 is initially raised. At this time, the cylinder does not move. When the acoustic foam body 6 is subsequently peeled off from the device, it can be lifted upward to complete the separation. Before this, the bottom plate 465, which is relatively stationary at the bottom of the lifting frame 463, will be kept in a downward pressing state to keep the acoustic foam body 6 from peeling off.

[0067] In order to achieve reliable and stable transfer of the acoustic foam body 6 for bonding operations, and to avoid problems such as falling off during the transfer process and offset during the bonding process, this embodiment has a second cylinder 468 fixedly installed above the base plate 465, that is, outside the lifting frame 463. The output shaft of the second cylinder 468 is mounted with a suction plate 469 for pressing on the base plate 465 and keeping the bottom level.

[0068] It should be noted that, as Figure 20 , Figure 21 The structure shown has a suction plate 469 with a pressing opening groove 4691 for pressing onto the base plate 465. The opening is for inserting the pressure arm plate 4651 on the outer side of the base plate 465. Symmetrically arranged suction holes 4693 and pin holes 4692 are located at the bottom of the suction plate 469 and on both sides of the pressure arm plate 4651. Suction is provided by a negative pressure pump pipe connected to the negative pressure hole 4694, which communicates with the suction hole 4693, allowing suction to be applied to the acoustic foam body 6. The acoustic foam body 6 is then fixedly inserted into the pin hole 4692 by a positioning pin 4610 to prevent displacement during contact. Because of the stability of the positioning pin 4610, the acoustic foam body 6 cannot be separated after depressurization alone. Therefore, a creative design is used with a return spring 464 cooperating with the base plate 465 to maintain the acoustic foam body 6 stably attached to the contact position based on pressure during the peeling of the positioning pin 4610. After the magnetic attraction closes, the return spring 464 is compressed, as... Figure 5 As shown, the bottom horizontal suction plate 469 and pressure arm plate 4651 are pressed together simultaneously. Then the suction plate 469 is lifted to separate the positioning pin 4610. Since the pressure arm plate 4651 still maintains the positioning of the acoustic foam body 6, the first cylinder 461 lifts the pressure arm plate 4651 to complete the separation. At this time, the acoustic foam body 6 is attached to the smart stylus.

[0069] It should be noted that in this embodiment, in order to determine and verify whether the bonding position is accurate, reference is made. Figure 9 , Figure 17 , Figure 19 For example, the intelligent stylus, the acoustic foam body 6, and the pressure plate 4651 are all equipped with calibration holes to facilitate verification of whether the bonding positions are aligned; therefore, in this embodiment, the operating box base 1 is equipped with such... Figures 1-4 The movable frame 2 shown includes a mounting frame 22 mounted on the forward and backward guide rail 21. A vertical plate 24 is mounted on the mounting frame 22 by a vertical slider 23. A camera 7 is mounted on the vertical plate by horizontal movement. The camera 7 is used to adjust the three-dimensional spatial position to align with the fitting position. The camera feeds back the calibration hole image to determine whether it is aligned.

[0070] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0071] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
