DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present application embodiment discloses a vehicle front-end frame metal accessory missing detection device, referring to Figure 2 , Figure 3 and Figure 4 , including a mounting platform 2, on which two positioning plates 3 are symmetrically bolted, a front end frame 1 equipped with metal accessories 14 is horizontally clamped between the two positioning plates 3, and the protrusions 13 on both sides of the front end frame 1 are respectively in contact with the positioning plates 3 on the corresponding sides. A plurality of mounting plates are bolted to the outside of the two cross bars 11 of the front end frame 1 on the mounting platform 2, and the number of mounting plates corresponds to the metal accessories 14 on the two cross bars 11. A first sensor 4 for detecting the metal accessories 14 on the cross bars 11 is plugged into the mounting plate. Two mounting frames 5 are horizontally oppositely slidably connected along a direction parallel to the cross bars 11 on the outside of the two side bars 12 of the front end frame 1 on the mounting platform 2, and a plurality of second sensors 51 for detecting the metal accessories 14 on the side bars 12 are plugged into the mounting frame 5. A third sensor 31 for detecting the metal accessories 14 on the protrusions 13 of the front end frame 1 is plugged into the positioning plate 3. The mounting platform 2 is provided with a first driving member 6 for driving the two mounting frames 5 to move. The first sensor 4, the second sensor 51 and the third sensor 31 are all operatively connected to a controller, and the controller is operatively connected to an alarm device 7. The alarm device 7 is used to sound an alarm when any sensor detects that the metal auxiliary part 14 is missing from the front frame 1.

[0020] In the embodiment of the present application, the front frame 1 is made of plastic, the first sensor 4, the second sensor 51 and the third sensor 31 are all metal sensors, and the alarm device 7 can be a buzzer or an indicator light. The front frame 1 is horizontally installed between the two positioning plates 3, and the two side protrusions 13 of the front frame 1 are respectively in contact with the positioning plates 3 on the corresponding sides. Then, the installation frames 5 on both sides are driven by the first driving member 6 to slide synchronously in opposite directions to approach the two side rods 12 of the front frame 1. Then all the first sensors 4, the second sensors 51 and the third sensors 31 are started to detect the positions for installing each metal auxiliary part 14 on the front frame 1. When any sensor detects that the metal auxiliary part 14 is missing on the front frame 1, the controller sends an execution signal to make the alarm device 7 sound an alarm. The controller can use a PLC integrated circuit system or a computer control system. The staff does not need to screen out the front frame 1 with the missing metal auxiliary part 14 one by one by human eyes, and the situation of missed detection is reduced. It has the advantages of reducing labor intensity and improving detection effect.

[0021] Furthermore, a pressing assembly 8 for pressing down and fixing the front end frame 1 is installed on the mounting platform 2. The pressing assembly 8 includes a plurality of rotary pressing cylinders 81, which are mounted on the mounting platform 2 and located on the inner side of the front end frame 1. The piston rods of the rotary pressing cylinders 81 are vertically upward and connected to a pressing block 82 at the end, and the pressing block 82 is located above the front end frame 1. When the front end frame 1 is horizontally mounted between the two positioning plates 3, the rotary pressing cylinder 81 is started to drive the pressing block 82 to rotate and move downward to press the front end frame 1 below. The stability of the front end frame 1 on the mounting platform 2 is further improved.

[0022] Specifically, the first driving member 6 includes a bidirectional cylinder. The bidirectional cylinder is horizontally mounted on the mounting platform 2 and is located on the inner side of the front frame 1. Piston rods are slidably arranged at both ends of the bidirectional cylinder, and the piston rods are parallel to the two flat side walls of the mounting frame 5. The piston rods of the two bidirectional cylinders are bolted to the mounting frames 5 on the corresponding sides. After the rotating clamping cylinder 81 is pressed down to fix the front frame 1, the bidirectional cylinder is started, and the mounting frames 5 on both sides can be driven to move synchronously in opposite directions and approach the corresponding side rods 12, so that the second sensor 51 can detect the metal accessories 14 on the side rods 12.

[0023] In order to improve the stability of the installation frame 5 during the sliding process, a slide rail 20 is horizontally arranged on the installation platform 2 below the installation frame 5 along the sliding direction of the installation frame 5. A slider is slidably connected to the slide rail 20, and the bottom bolt of the installation frame 5 is connected to the slider.

[0024] Furthermore, a stamping mechanism for stamping a qualified mark on the inner side wall of the crossbar 11 is also installed on the mounting platform 2. The stamping mechanism includes a push block 9 with a qualified mark engraved on the surface, and the push block 9 is horizontally slidably arranged on the mounting platform 2 in a direction perpendicular to the crossbar 11, and the qualified mark on the push block 9 faces the inner side wall of the crossbar 11. A second driving member 10 for driving the push block 9 to move is installed on the mounting platform 2.

[0025] In the embodiment of the present application, the qualified mark can be the first letter of the pinyin of the word "qualified", or other symbols. When the first sensor 4, the second sensor 51 and the third sensor 31 all detect that the metal accessories 14 on the front end frame 1 are fully installed, the second drive member 10 can drive the push block 9 to abut against the inner wall of the corresponding cross bar 11. Since the front end frame 1 is made of plastic, the qualified mark is easily printed on the cross bar 11. In other embodiments of the present application, the second drive member 10 can be connected to the controller. When the first sensor 4, the second sensor 51 and the third sensor 31 all detect that the metal accessories 14 on the front end frame 1 are fully installed, the controller controls the second drive member 10 to start, thereby pushing the push block 9. In this way, only the front end frame 1 with the qualified mark printed on it can be used for automobile assembly, which further improves the control of product quality.

[0026] Specifically, the second driving member 10 includes a cylinder. The cylinder is mounted on the mounting platform 2 and located on the inner side of the front frame 1. The piston rod of the cylinder is horizontally perpendicular to the two cross bars 11 of the front frame 1. The push block 9 is bolted to the end of the piston rod of the cylinder. The cylinder drives the piston rod to slide, so that the push block 9 can be pushed to press the inner side of the cross bar 11.

[0027] The implementation principle of the device for detecting missing metal accessories of the front-end frame of an automobile in the embodiment of the present application is as follows: the front-end frame 1 is horizontally installed between two positioning plates 3, and the two side protrusions 13 of the front-end frame 1 are respectively in contact with the positioning plates 3 on the corresponding sides; then the first driving member 6 is used to drive the installation frames 5 on both sides to slide synchronously in opposite directions to approach the two side rods 12 of the front-end frame 1; then all the first sensors 4, second sensors 51 and third sensors 31 are started to detect the positions on the front-end frame 1 for installing each metal accessory 14. When any sensor detects that a metal accessory 14 is missing on the front-end frame 1, the alarm device 7 sounds an alarm to prompt the staff. The staff does not need to screen out the front-end frames 1 with missing metal accessories 14 one by one by human eyes, and the situation of missed detection is reduced. It has the advantages of reducing labor intensity and improving detection effect.
