While meeting normal transportation needs, the public is increasingly concerned about the safety and additional functional attributes of cars. As a necessity for the safety and functionality of cars in today's society, on-board cameras are of indispensable importance in terms of safety, accident records, and convenience during driving.

[0003] The existing technology has the following disadvantages when pre-assembling the front shell and the rear shell of the vehicle camera:

[0004] Firstly, in the past daily production, poor contact of products always occurred. After verification and analysis, it was found that when pre-assembly is performed manually by hand, the front shell and the back shell cannot ensure that the height of the product remains consistent after each pre-assembly, which may cause problems in the subsequent production process.

[0005] Secondly, during manual assembly, since the operator can only observe with the naked eye whether there is any installation error or misalignment, due to long-term operation and different levels of proficiency of the personnel, it cannot be guaranteed that each installation is correct. Misalignment may occur, which will directly lead to product scrapping and increase the company's losses.

[0029] The present invention will be further described with reference to the accompanying drawings.

[0030] like Figures 1 to 9As shown, a pre-assembly device for the front and rear shells of a vehicle-mounted camera includes a vacuum generator, an assembly frame, a lifting device 2, an upper mold 4, a lower mold 6, an upper pressure block 42-1, a lower pressure block 62, a laser sensor 57, a pressure gauge 56, a nitrogen buffer 53, a buffer bracket 54, a lower adjustment device and a switch 16.

[0031] The assembly frame includes an assembly base plate 11 and a fixed bracket, which is fixed on the assembly base plate 11. The fixed bracket includes four columns 12 and a fixed seat 13. The column 12 is fixed on the assembly base plate 11, and the fixed seat 13 is fixed on the column 12. The column 12 is convenient for installing other components. The lifting device 2 adopts a slide cylinder, which is fixed on the fixed seat 13 and is vertically arranged. The slide cylinder has a simple structure and is easy to install. It has a guiding function and simplifies the lifting structure. The top of the upper mold 4 is fixed to the slide of the slide cylinder through a buffer plate 31. The bottom of the upper mold 4 is provided with an upper positioning groove 41. The upper positioning groove 41 matches the rear shell 91. The rear shell 91 is inserted into the upper positioning groove 41, and the upper positioning groove 41 is slightly larger than the rear shell 91. Four upper slide grooves 42-2 are provided on the four corners of the upper positioning groove 41, and the upper slide grooves 42-2 are communicated with the upper positioning groove 41. Four upper pressing blocks 42-1 are provided, and upper pressing grooves 43 are provided at the ends of the upper pressing blocks 42-1. The upper pressing grooves 43 match the four prisms of the rear shell 91. The upper pressing block 42-1 is also provided with a waist-shaped upper fixing hole 44, and the upper fixing hole 44 is arranged along the axis of the upper slide groove 42-2. The upper pressing block 42-1 is installed in the upper slide groove 42-2, and the upper fixing hole 44 is fixed in the upper slide groove 42-2 by screws. The upper fixing hole 44 facilitates the adjustment of the position of the upper pressing block 42-1. The upper pressing grooves 43 reduce the contact area with the front shell 92, and the positioning is more accurate. Quick plug connectors 51 are installed on both sides of the upper mold 4, and the quick plug connectors 51 are communicated with the upper positioning groove 41, and the quick plug connectors 51 are connected to the vacuum generator.

[0032] like Figure 5 and Figure 6 As shown, the top of the lower mold 6 is provided with a lower positioning groove 61 and a lower sliding groove 64, the lower positioning groove 61 matches the front shell 92, the front shell 92 is inserted into the lower positioning groove 61, and the lower positioning groove 61 is slightly larger than the rear shell 91. The lower positioning groove 61 is connected to the lower sliding groove 64, and the top of the lower pressing block 62 is provided with a lower fixing hole 63, which is a waist-shaped hole and is arranged along the axis of the lower sliding groove 64. The lower fixing hole 63 facilitates the adjustment of the position of the lower pressing block 62.

[0033] The lower adjustment device includes a lower adjustment plate 71, an upper adjustment plate 72, a lower positioning pin 73 and an upper positioning pin 74. The lower adjustment plate 71 is fixed on the assembly base plate 11; the upper adjustment plate 72 is provided with a waist-shaped positioning adjustment hole 721, and the positioning adjustment hole 721 is fixed to the lower adjustment plate 71 by bolts, and the lower mold 6 is fixed to the upper adjustment plate 72; the lower positioning pin 73 is fixed to the lower adjustment plate 71 and is located on both sides of the upper adjustment plate 72 to limit the position of the upper adjustment plate 72; the upper positioning pin 74 is fixed to the upper adjustment plate 72 and is located on both sides of the lower mold 6 to limit the position of the lower mold 6.

[0034] The laser sensor 57 is mounted on the assembly base plate 11 and is located on one side of the lower mold 6, and is used to detect whether the front shell 92 is installed. The pressure gauge 56 is fixed on the assembly base plate 11 and is located at one end of the assembly base plate 11. The pressure gauge 56 is connected to the vacuum generator and is used to display the pressure. The pressure gauge 56 adopts a digital display.

[0035] The nitrogen buffer 53 is mounted on the buffer plate 31 and is located on one side of the upper mold 4. The buffer bracket 54 is mounted on the assembly base plate 11 and is arranged opposite to the nitrogen buffer 53. When the upper mold 4 drives the rear shell 91 to descend to the front shell 92, the nitrogen buffer 53 can reduce the descending speed of the rear shell 91 to prevent the front shell 92 from being crushed by the excessive speed.

[0036] There are two switches 16 , which are fixed on both sides of the assembly base plate 11 , respectively. The slide cylinder can only be started when the two switches 16 are pressed down at the same time.

[0037] In the initial state, the front shell 92 is not placed on the lower mold 6, the laser sensor 57 does not sense the product, and the vacuum generator does not work, saving compressed air and reducing energy consumption. At this time, the switch 16 does not work. The front shell 92 is installed in the lower positioning groove 61, the laser sensor 57 will sense the front shell 92, the vacuum generator is started, and the rear shell 91 is inserted into the upper positioning groove 41. The rear shell 91 can be perfectly adsorbed on the upper mold 4 without falling. At the same time, the pressure gauge 56 can detect the change in pressure, and compare it with the pre-given value to observe whether there is a deviation, and reflect whether the rear shell 91 is completely adsorbed in the upper mold 4 from the intuitive digital. After the product is placed, press the switch 16 with both hands, the slide cylinder will automatically press down, and the nitrogen buffer 53 will buffer when the rear shell 91 contacts the front shell 92. When the rear shell 91 is pressed onto the front shell 92, the slide cylinder will stay at the downward position for 2S to ensure that the pressing position of the pre-assembled product is in place. When the assembly is completed, the vacuum generator stops working, the upper mold 4 releases the rear shell 91, the slide cylinder retracts, and the operator only takes off the pre-assembled product.

[0038] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the protection scope of the claims of the present invention.
