[0034] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0035] Embodiment one

[0036] The present embodiment relates to a hot riveting head, which is beneficial to improve the riveting quality and efficiency.

[0037] In the overall structure, as shown in Figures 1 to 4 The hot riveting head of the present embodiment includes a main body 1 made of a heat-conducting material, and a riveting head 101 provided at one end of the main body 1. The main body 1 is provided with a channel 110 for the passage of gas to cool at least the riveting head 101. The riveting head 101 is provided with a molding portion 1010 for riveting the end of the hot riveting column to a predetermined shape.

[0038] It should be noted that when the hot riveting head of the present embodiment is used to assist in the riveting of the CCS assembly, a riveting column is reserved on the plastic suction bracket, and a through hole is reserved on the aluminum bar or FPC (Flexible Printed Circuit). When the aluminum bar or FPC is installed, the riveting column on the plastic suction bracket passes through the through hole, and the riveting column has a protruding portion protruding from the surface of the aluminum bar or FPC. During hot riveting, the protruding portion is softened and pressed tightly by the hot riveting head and cooled. In this way, the aluminum bar and the plastic suction bracket, or the FPC and the plastic suction bracket are riveted and assembled together.

[0039] At this time, in the structure, the hot riveting head is made of heat-conducting material, which is beneficial to the rapid heating of the riveting head 101 and the smooth progress of the hot riveting. Moreover, the channel 110 arranged in the main body 1 can at least cool the riveting head 101 by the gas entering into the channel 110 after the hot riveting head completes the hot riveting, so as to realize the rapid cooling of the riveting head 101, facilitate the demolding after the rivet hot riveting, ensure the appearance of the rivet point, and also ensure that the pull-out force of the rivet point meets the use requirement, thereby facilitating the improvement of the riveting quality and the riveting efficiency.

[0040] In detail, continuing to refer to Figures 1 to 4 In the embodiment, the main body 1 includes a connecting block and a cylinder which are connected. The riveting head 101 is arranged at the end of the cylinder away from the connecting block. As a preferred embodiment, the connecting block and the cylinder are formed in one body.

[0041] In the embodiment, the plastic part 1010 at the end of the riveting head 101 is a feasible embodiment, which includes a plastic flat surface arranged at the end of the riveting head 101. Of course, as another feasible embodiment, the plastic part 1010 can also include a plastic groove arranged at the end of the riveting head 101. At this time, the plastic part 1010 adopts the plastic flat surface or the plastic groove, which is simple in structure, convenient for the design and preparation of the riveting head 101, and can ensure the quality of the rivet point. Moreover, when the plastic part 1010 adopts the plastic groove, the forming quality of the rivet point can be further improved.

[0042] Still referring to Figures 1 to 4 In the embodiment, the channel 110 includes a cavity extending from one end of the main body 1 to the direction of the riveting head 101. Specifically, the cavity penetrates through the connecting block and extends into the cylinder, and the bottom wall of the cavity is formed by the top of the plastic part 1010. Moreover, the main body 1 is also provided with a slit 100, which is arranged along the axial direction of the cavity and communicates with the cavity. At this time, the cavity arranged in the main body 1 and the communication between the slit 100 and the cavity can increase the cooling area, so as to facilitate the rapid cooling of the main body 1 and the rapid cooling of the riveting head 101, and further facilitate the demolding after the rivet hot riveting and ensure the appearance of the rivet point.

[0043] As a preferred embodiment, in the embodiment, the hot riveting head is made of titanium alloy TC4 or die steel S136. At this time, the characteristics of the above-mentioned materials can ensure the hardness of the hot riveting head, so that the hot riveting head is resistant to high temperature and is not easy to deform, has a long service life, and has good heat-conducting performance, which is beneficial to the rapid heating of the riveting head 101.

[0044] In addition, in the embodiment, the body part 1 is provided with a connecting part for connecting with the heating part in the hot riveting device. In this way, the hot riveting head is connected with the heating part in the hot riveting device. The body part 1 is heated by the heating part, i.e. the riveting head 101 is heated, so that the hot riveting column on the plastic suction support is heated and softened, ensuring the smooth progress of the hot riveting.

[0045] As shown in Figures 1 to 4 , the connecting part specifically includes a plurality of connecting holes 111 arranged on the body part 1, and the body part 1 is connected with the heating part through the connecting part. The heating part includes a heating wire and a copper sheet connected to the heating wire. In specific implementation, the copper sheet is wrapped around the body part 1 and connected to the body part 1 through a connecting screw.

[0046] When the hot riveting head is heated, the heat of the copper sheet is transferred to the body part 1 and the riveting head 101, so that the riveting head 101 is heated to a certain temperature. In hot riveting, the side of the plastic suction support away from the riveting column is provided with a clamping part for clamping on the riveting column position. When the hot riveting head is pressed down, the clamping part is tightly clamped, so that the protruding part of the riveting column is pressed into a predetermined shape.

[0047] Embodiment two

[0048] The embodiment relates to a hot riveting device provided with the hot riveting head of the first embodiment.

[0049] As a better embodiment, as shown in Figure 5 and Figure 6 , in the embodiment, the blowing pipe 2 in the hot riveting device extends into the channel 110 in the body part 1, and the distance L between the air outlet of the blowing pipe 2 and the top of the riveting head 101 is between 3mm and 5mm. At this time, the blowing pipe 2 extends into the channel 110, and the distance between the air outlet of the blowing pipe 2 and the top of the riveting head 101 is limited, which can further ensure the gas flow into the channel 110 and further improve the cooling effect of the riveting head 101.

[0050] In specific implementation, the distance L can be 3mm, 4mm or 5mm. In addition, the diameter of the blowing pipe 2 is smaller than the diameter of the cavity, i.e. a gap is formed between the blowing pipe 2 and the inner wall of the cavity. When the blowing pipe 2 blows, the gas discharged from the air outlet of the blowing pipe 2 can directly act on the top of the riveting head 101, which is beneficial to the rapid cooling of the riveting head 101. At the same time, the discharged gas can flow through the gap between the blowing pipe 2 and the inner wall of the cavity and finally be discharged through the slit 100. At this time, the flow of the gas can also cool the body part 1, which can further improve the cooling effect of the riveting head 101.

[0051] The hot riveting device of the embodiment is favorable for demolding after hot riveting of the riveting column by adopting the hot riveting head of the first embodiment, and is also favorable for guaranteeing the appearance of the riveting point, and can also guarantee that the drawing force of the riveting point meets the use requirement, so that the hot riveting efficiency and the hot riveting quality can be improved.

[0052] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
