Description

Technical Field

[0001] This application relates to, but is not limited to, the field of mobile phone manufacturing technology, and in particular to a hot pressing device. Background Technology

[0002] In the processing of mobile phone components, metal sheets (such as nickel and copper) are often hot-pressed with PI adhesive to form the desired components. In related technologies, the materials are typically fed manually into a hot-pressing machine for hot pressing. However, in practical applications, to ensure production efficiency, the metal sheets are often quite long, requiring multiple manual movements of the metal sheet and PI adhesive. This method is prone to missed pressing, and manual feeding cannot ensure that the material strip delivered to the hot-pressing area of ​​the hot-pressing assembly is horizontal, easily leading to poor hot-pressing. Therefore, there is an urgent need for a hot-pressing device that can improve the pressing efficiency and yield rate of the metal strip formed by the metal sheet and PI adhesive.

[0033] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0034] Reference Figures 1 to 5 As shown, the hot pressing apparatus according to an embodiment of this application includes:

[0035] The feeding assembly includes a metal strip feeding component 110; the metal strip feeding component 110 is used to feed metal strip.

[0036] Support assembly 200 is located on the first side of metal strip feeding member 110. Support assembly 200 is provided with a support plane to support horizontal conveying of metal strip.

[0037] The hot pressing assembly 300 is provided with a hot pressing zone 310. The hot pressing assembly 300 is located on the first side of the support assembly 200 away from the metal strip feeding member 110, and the plane where the hot pressing zone 310 is located is parallel to the support plane so that the metal strip enters the hot pressing zone 310 horizontally. The hot pressing assembly 300 is used to perform hot pressing treatment on the metal strip in the hot pressing zone 310.

[0038] The material receiving assembly 400 includes a metal strip receiving component 410 and a first puller 420. The first puller 420 is located on the first side of the hot pressing assembly 300 away from the support component 200. The first puller 420 is used to repeatedly pull the metal strip horizontally a preset distance and then stop for a preset hot pressing time. The metal strip receiving component 410 is located on the first side of the first puller 420 away from the hot pressing assembly 300. The metal strip receiving component 410 is used to wind up the hot-pressed metal strip.

[0039] Therefore, by providing the metal strip feeding component 110, continuous feeding of the metal strip can be achieved. By setting the first feeder 420, the metal strip can be stopped at preset intervals to facilitate pressing by the hot pressing assembly 300, ensuring continuous hot pressing of the metal strip and reducing the probability of missed pressing. Simultaneously, the metal strip receiving component 410 collects the hot-pressed strip, reducing the probability of manual intervention and increasing hot pressing efficiency. Furthermore, by setting the support component 200, the metal strip enters the hot pressing zone 310 horizontally, resulting in better hot pressing and reducing the probability of defective hot pressing marks. Therefore, the embodiments of this application can improve the pressing efficiency of the metal strip and the yield rate of the pressed product.

[0040] Understandably, the metal strip is a strip formed by laminating metal material and PI adhesive.

[0041] The metal strip feeding component 110 can be simply configured as a rotatable drum. The metal strip taking component 410 can include a drum and a drive component, which can be a motor, cylinder, or other drive that can drive the drum to rotate. The drive will rotate the corresponding drum, allowing feeding to occur simultaneously with taking the strip. Alternatively, the metal strip feeding component 110 can include both a drum and a drive component; therefore, this embodiment does not limit the composition of the metal strip feeding component 110.

[0042] The embodiments of this application do not limit the structure of the support component 200, and those skilled in the art can selectively set it according to actual needs.

[0043] The hot press assembly 300 includes an upper pressing mold, a lower pressing mold, and a pressing drive (such as a motor or cylinder). The pressing drive controls the upper and lower pressing molds to perform pressing. This application embodiment does not limit the pressing parameters such as temperature and pressure of the hot press assembly 300; those skilled in the art can selectively set these parameters according to actual needs.

[0044] The embodiments of this application do not limit the structure of the first feeder 420, and those skilled in the art can selectively set it according to actual needs.

[0045] Understandably, referring to Figure 2 and Figure 3 As shown, the support assembly 200 includes a support frame 210 and two positioning rollers 220. The two positioning rollers 220 are arranged vertically and vertically with a gap. The support frame 210 is located between the positioning rollers 220 and the metal strip feeding component 110. The upper surface of the support frame 210 forms a support plane and is parallel to the plane where the hot pressing zone 310 is located.

[0046] By setting two positioning rollers 220 vertically, the height direction can be limited, and by setting the support component 200, the material belt can be kept as horizontal as possible.

[0047] Understandably, referring to Figure 1 , Figure 2 as well as Figure 4 As shown, the feeding assembly also includes an upper resist film feeding component 120 and a lower resist film feeding component 130, which are located above and below the metal strip feeding component 110, respectively. The upper resist film feeding component 120 is used to feed the upper resist film to the hot pressing zone 310; the lower resist film feeding component 130 is used to feed the lower resist film to the hot pressing zone 310. The receiving assembly 400 includes an upper resist film receiving component 430 and a lower resist film receiving component 440, which are used to wind up the hot-pressed upper resist film and the lower resist film receiving component 440.

[0048] This application does not limit the materials of the upper and lower resist films, and those skilled in the art can selectively set them according to actual needs. It is understood that in some embodiments, both the upper and lower resist films pass through the gap between the two positioning rollers 220 into the hot-pressing zone 310. Positioning the upper resist film feeder 120 and the lower resist film feeder 130 close to the hot-pressing assembly 300 can shorten the conveying distance of the upper and lower resist films.

[0049] Understandably, referring to Figure 4 and Figure 5As shown, the receiving assembly 400 also includes two second material pullers 450. The two second material pullers 450 are located on the first side of the hot pressing assembly 300 and on the upper and lower sides of the first material puller 420. The two second material pullers 450 are used to repeatedly pull the lower and upper resist films horizontally a preset distance and then stop the preset hot pressing time.

[0050] By providing a second feeder 450 for both the upper and lower resist film, the first feeder 420 and the second feeder 450 can be adjusted and tested separately, thereby improving the efficiency of the adjustment and testing.

Material belt openings 540 are provided on the two adjacent sides of the third housing 530 and the first housing 510, and on the two adjacent sides of the third housing 530 and the housing, to ensure the conveying of the material belt.

[0052] By providing housings for the feeding assembly, receiving assembly 400 and hot pressing assembly 300 respectively, the hot pressing assembly 300, feeding assembly and receiving assembly 400 can be isolated and assembled using existing equipment, thereby reducing the R&D cost of the device.

[0053] It is understood that some components of the feeding assembly may be placed inside the first housing 510, and some may be located on the outer wall of the first housing 510. In other embodiments, all components may be placed inside the first housing 510. Therefore, this application does not limit how the feeding assembly is packaged through the first housing. For example, as shown... Figure 1 As shown, the metal strip feeding component 110 is installed on the outer side of the first side wall of the first housing 510, and the upper resist film feeding component 120 and the lower resist film feeding component 130 are both located inside the first housing 510.

[0055] Understandably, the start button, temperature display 610, and control display 620 are all located on the surface of the third housing 530, which can improve safety during use.

[0056] For example, such as Figure 4 As shown, the temperature display 610 has two parts, which display the upper mold temperature and the lower mold temperature respectively.

[0057] Understandably, referring to Figure 4 As shown, the hot pressing device also includes a display mounting bracket 630, which is configured as a right-angle bracket, with the control display screen 620 and the hot pressing assembly 300 connected to its two ends respectively.

[0058] Understandably, in some embodiments, the two ends of the right-angle bracket can also be rotatably configured with corresponding connected components, such as the end of the right-angle bracket being rotatably configured with the control display screen 620. The end of the right-angle bracket is rotatably configured with the hot-pressing assembly 300.

[0059] Understandably, the third housing 530 is also equipped with a safety sensor to provide a safe distance warning.

[0060] Safety sensing devices can be configured as optical gratings or similar components.
