[0002] Automotive injection-molded air ducts are frequently used in automotive air conditioning systems. These ducts typically consist of an upper cover and a lower cover that snap together to form a duct assembly. Existing automotive air ducts are assembled manually by snapping the buckles of the upper cover into the rings of the lower cover. However, due to the numerous buckles on the upper cover, manual assembly is inefficient and buckles often miss or fail to snap into place, resulting in substandard air leakage and reduced duct quality.

[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0026] like Figure 1-5The figure shows an automobile air duct assembly and detection equipment, comprising a base 1, a support plate 2 is provided above the base 1, both ends of the bottom of the support plate 2 are fixedly connected to a fixing plate 11, the bottom of the fixing plate 11 is fixed to the top of the base 1, a plurality of support columns 3 are installed on the top of the base 1, a photoelectric sensor 4 is installed on the right side of the support column 3, and two oppositely arranged splints 12 are fixedly connected to the left side of the support column 3, the side of the two splints 12 close to each other is a concave arc surface, and a cylindrical shielding rod 5 is slidably connected between the two splints 12, and a soft pad 13 for placing a clamping ring 21 of the lower cover of the air duct is fixedly connected to the top of the support column 3. The soft pad 13 can buffer the pressure on the air duct to prevent the air duct from being crushed; a positioning block 14 is fixedly connected to the inside of the soft pad 13, and a pressure rod 6 is fixedly connected to the top of the shielding rod 5. The top of the rod 6 passes through the positioning block 14 and contacts the bottom of the buckle 22 on which the air duct cover is placed, and the pressure rod 6 is pushed downward by the bottom of the buckle 22, thereby driving the shielding rod 5 to move downward; the bottom of the positioning block 14 and the top of the shielding rod 5 are connected by a spring 15. When the shielding rod 5 moves downward, the spring 15 is stretched so that the shielding rod 5 is not subjected to the action of external force, and the elastic action of the spring 15 drives the shielding rod 5 to return to its initial position; a through hole 7 is provided on the support column 3 and between the photoelectric sensor 4 and the shielding rod 5. When the shielding rod 5 is in its initial position without the action of external force, the sensing end of the photoelectric sensor 4 passes through the through hole 7 without sensing any object. When the shielding rod 5 moves downward and moves in front of the sensing end of the photoelectric sensor 4, the photoelectric sensor 4 will send a signal after sensing the shielding rod 5.

[0027] An alarm is installed on the top of the base 1, and a cylinder 8 and a panel 16 are installed on the top of the support plate 2. A display light 9 electrically connected to the photoelectric sensor 4 in a one-to-one correspondence is installed on the panel 16. A controller is provided inside the panel 16. The alarm, the display light 9 and the photoelectric sensor 4 are all electrically connected to the controller. The photoelectric sensor 4 transmits a signal to the controller, and the controller controls the display light 9 corresponding to the photoelectric sensor 4 to light up. If the display light 9 is not all lit, the controller will also control the alarm to sound an alarm; a pressure plate 17 is installed on the output end of the cylinder 8, and a pressure head 10 corresponding to the support column 3 is installed at the bottom of the pressure plate 17. The pressure head 10 is connected to the buckle The top of 22 contacts, drives the pressure plate 17 to press down through the cylinder 8, and the pressure plate 17 drives the pressure head 10 to press down, so that the pressure head 10 pushes the buckle 22 to press down; the pressure plate 17 is located between the two fixed plates 11, and the two fixed plates 11 are close to each other on one side. A slide rail 18 is installed on the pressure plate 17 and is slidably connected to the slide rail 18. Through the cooperation of the slider 19 and the slide rail 18, the pressure plate 17 will not shake during the downward pressing process, thereby improving stability; a limiting column 20 is installed on the top of the base 1, and the limiting column 20 is located directly below the pressure plate 17. The limiting column 20 can prevent the pressure plate 17 from being excessively pressed down to avoid damaging the air duct.

[0028] Working principle:

[0029] like Figure 1-5 As shown, when the assembly inspection device is used, the assembled air duct is first placed on the cushion block 13 of the support column 3, and the clamping ring 21 of the air duct lower cover is aligned with the cushion block 13. At this time, the top of the clamping buckle 22 of the air duct upper cover is aligned with the pressure head 10, and the cylinder 8 is started. The cylinder 8 drives the pressing plate 17 to press down, and the pressing plate 17 drives the pressure head 10 to press down, so that the pressure head 10 pushes the clamping buckle 22 downward, and the clamping buckle 22 is buckled into the clamping ring 21, replacing the traditional manual assembly of the air duct and improving the assembly efficiency.

[0030] After the buckle 22 is buckled into the buckle ring 21, the bottom of the buckle 22 will contact the top of the pressure rod 6. As the pressure head 10 continues to press downward, it will push the pressure rod 6 downward, thereby driving the shielding rod 5 to move downward, so that the shielding rod 5 moves in front of the sensing end of the photoelectric sensor 4. After the photoelectric sensor 4 senses the shielding rod, it will send a signal and transmit it to the controller. The controller then controls the display light 9 corresponding to the photoelectric sensor 4 to light up. If the buckle 22 is fully buckled into the buckle 21, the display light 9 will all light up. On the contrary, if the buckle is missed or not buckled in place, it proves that the pressure head 10 did not push the buckle 22 downward or The buckle 22 is pushed down but is not completely buckled into the snap ring 21. In this case, although the pressure head 10 is pressing down, due to the lack of good contact between the buckle 22 and the pressure rod 6, the pressure head cannot push the pressure rod 6 downward or cannot push the pressure rod 6 to move downward in front of the sensing end of the photoelectric sensor 4. In this way, the shielding rod 5 will not sense, so that the display light 9 corresponding to the missed or unfastened buckle 22 will not light up, and the controller will also control the alarm to sound an alarm, prompting the product NG. The missed or unfastened buckle 22 can be reinserted to avoid air leakage in the air duct and substandard conditions, thereby improving the quality of the air duct.
