Description

Technical Field

[0001] This utility model relates to a hot riveting device, belonging to the technical field of riveting devices. Background Technology

[0002] In the production of PCBA boards and housings for some electronic products, the traditional method is mostly manual operation of the hot riveting tool: the operator holds the hot riveting head, aligns it with the riveting positioning post on the housing, and manually applies force to complete the hot riveting. This method has two problems: first, the manual force is unstable, which can easily lead to uneven shaping of the positioning post during hot riveting, resulting in insufficient strength of the limiting part or damage to the PCBA board; second, manual operation relies on dedicated hot riveting equipment, which is difficult to integrate into non-standard automated production equipment, requiring additional equipment costs, and is inefficient when switching processes, making it difficult to adapt to the needs of mass production.

[0003] The aim is to solve these problems by creating a modular hot riveting mechanism that can be flexibly adapted to non-standard equipment, thereby reducing equipment investment and improving hot riveting stability and assembly efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a hot riveting device is provided, which includes a fixed base and a vertically arranged sliding shaft. The fixed base includes a top plate and a bottom plate, the bottom plate being located below the top plate. The sliding shaft passes through the top plate and the bottom plate and can slide up and down within the top plate and the bottom plate. A slide rail is vertically arranged on the fixed base. A slider is arranged above the bottom plate. One side of the slider is slidably arranged on the slide rail. The lower end of the sliding shaft passes through the slider and extends downward beyond the slider. A spring is sleeved on the sliding shaft. The spring is located between the top plate and the slider. A hot riveting head is arranged at the lower end of the sliding shaft. A heating copper block is arranged on one side of the hot riveting head.

[0005] Preferably, an insulating block is provided above the hot riveting head and the heated copper block.

[0006] Preferably, the sliding shaft is a hollow shaft with openings at both ends.

[0007] Preferably, a thermocouple is provided on the slider.

[0008] Preferably, the top of the sliding shaft is provided with a drive mechanism for driving the sliding shaft to move up and down.

[0009] Preferably, the driving mechanism is a pneumatic cylinder or an electric cylinder.

[0010] The beneficial effects of this utility model are: the hot riveting device of this utility model can be used for hot riveting and fixing of PCBA boards and housings, and can be flexibly adapted to the modular hot riveting mechanism of non-standard equipment, so as to reduce equipment investment and improve the stability and assembly efficiency of hot riveting.

[0011] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort, wherein: Figure 1 This is a schematic diagram of the structure of the hot riveting device of this utility model. Detailed Implementation

[0012] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] Please see Figure 1 A hot riveting device includes a fixed base 1 and a vertically arranged sliding shaft 2. The fixed base 1 includes a top plate 3 and a bottom plate 4, with the bottom plate 4 located below the top plate 3. The sliding shaft 2 passes through the top plate 3 and the bottom plate 4 and can slide up and down within the top plate 3 and the bottom plate 4. A slide rail 5 is vertically arranged on the fixed base 1. A slider 6 is arranged above the bottom plate 4, with one side of the slider 6 slidably mounted on the slide rail 5. The lower end of the sliding shaft 2 passes through the slider 6 and extends downward beyond the slider 6. A spring 7 is sleeved on the sliding shaft 2, with the spring 7 located between the top plate 3 and the slider 6. A hot riveting head 8 is arranged at the lower end of the sliding shaft 2, and a heating copper block 9 is arranged on one side of the hot riveting head 8.

[0014] Preferably, an insulating block 10 is provided above the hot riveting head 8 and the heated copper block 9.

[0015] Preferably, the sliding shaft 2 is a hollow shaft with openings at both ends.

[0016] Preferably, a thermocouple 11 is provided on the slider 6, and the thermocouple 11 monitors the temperature of the hot riveting head 8 in real time to ensure that the heating temperature is kept within the set range.

[0017] Preferably, the top of the sliding shaft 2 is provided with a drive mechanism 12 for driving the sliding shaft 2 to move up and down.

[0018] Preferably, the driving mechanism 12 is a pneumatic cylinder or an electric cylinder, or it can be a corresponding mechanism for non-standard equipment to drive the sliding shaft 2 to move up and down. The hot riveting device of this utility model can be adapted to the modular hot riveting mechanism of non-standard equipment. The hot riveting device of this utility model can also be used as a component of the modular hot riveting mechanism of non-standard equipment to reduce equipment investment and improve the stability and assembly efficiency of hot riveting.

[0019] When this hot riveting device is in operation, the PCBA board and housing to be riveted are fixed below the hot riveting head 8. The heating copper block 9 is energized to heat the hot riveting head 8. The drive mechanism 12 drives the sliding shaft 2 downwards, causing the hot riveting head 8 to move downwards as well. The hot riveting head 8 moves downwards to the riveting positioning post of the housing to be riveted. The riveting positioning post can float upwards (a spring can be installed under the riveting positioning post), generating an upward force on the hot riveting head 8. The slider 6 slides upwards, and the spring 7 is compressed, generating a rebound force. After the forces are balanced, the hot riveting head 8 is stationary, and the hot riveting head 8 performs the hot riveting. After the riveting time is up, the hot riveting ends, and the sliding shaft 2 and the hot riveting head 8 move upwards. Compressed gas is blown through the hollow hole in the sliding shaft 2 to the riveting area, rapidly cooling the riveting point.
