Description

Technical Field

[0001] The present invention relates to the technical field of automobile coat rack detection tooling, and specifically provides an automobile coat rack vision detection tooling and a detection method therefor. Background Art

[0002] After the assembly of the automobile coat rack is completed, it needs to be placed on the tooling for inspection. The inspection includes vision inspection and laser inspection. The vision inspection is used to detect whether the installation positions and directions of components such as child locks and sponges on the automobile coat rack are correct. The laser inspection is used to detect the edge of the small hole on the edge of the automobile coat rack by using a laser sensor to detect the excellent opening of the small hole. The specific structure is as shown in the automobile coat rack vision detection tooling disclosed in the existing publication number CN206235579U; The inspection tooling provided by the above-mentioned prior art greatly improves the inspection efficiency and accuracy compared with the traditional manual inspection. However, there are still certain problems in the actual use process: When the automobile coat rack is installed, since it is directly spread on the sheet metal in the rear row of the automobile, it does not require high hardness. And because it needs to play a certain buffering effect, the existing automobile coat rack has a certain softness. And due to the requirements of the automobile shape, the automobile coat rack is mostly arranged in an L shape. The small hole that needs to be detected by laser is opened on the shorter side of the L-shaped automobile coat rack. In the actual inspection process, after the automobile coat rack is spread on the tooling manually, the automobile coat rack is not stable after being placed firmly because it is soft and movable. Therefore, each time it is spread on the tooling, it cannot ensure that the small hole is always directly facing the laser sensor. It is necessary to manually press the long side part of the automobile coat rack to make it fit the tooling stably, and then press the short side part of the automobile coat rack to ensure that the short side part fits the tooling to ensure that the small hole can be accurately aligned with the laser sensor. Otherwise, the inspection cannot be carried out normally. After such operation, after the small hole inspection is completed, the operator leaves and then conducts the vision inspection. In order to ensure normal inspection, there are many manual operation steps and the operation is cumbersome, which greatly increases the manual labor intensity during inspection. At the same time, the existing technology only uses one inspection station, resulting in the need to manually remove the inspected automobile coat rack after the inspection is completed, and then load a new coat rack before continuing the inspection work, with low inspection efficiency.

[0003] Therefore, it is necessary to provide an automobile coat rack vision detection tooling and a detection method therefor to solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 6 The embodiment of the present invention provides a technical solution: a visual inspection tool for automobile coat racks, comprising a tool frame 1, a stabilizing component and a visual inspection component, two jigs 2 are symmetrically fixed in the middle of the tool frame 1, a plurality of laser detection devices are fixed at equal intervals on one side of the jig 2, notches 201 are formed at equal intervals on the opposite sides of the two jigs 2, a mounting frame 202 is fixed on the inner wall of the notch 201, the laser detection device comprises a laser sensor 8 fixed on the inner wall of the mounting frame 202, the stabilizing component is mounted on the tool frame 1, and is used for laser inspection of automobile coat racks. During the inspection, the visual inspection component is kept close to the clothes rack. The visual inspection component is fixed on the stabilizing component and is used to perform visual inspection on the automobile clothes rack. The stabilizing component includes a rotating component 3 installed in the middle of the upper end of the tooling frame 1, a lifting component 4 fixed on the rotating component 3, a carrier plate 5 fixed on the protruding end of the lifting component 4, a longitudinal pressing component 6 fixed on the carrier plate 5, and a transverse pressing component 7 fixed on the carrier plate 5. The carrier plate 5 is facing a mold 2, and openings 51 are symmetrically opened on the carrier plate 5. The visual inspection component includes a CCD camera 11 fixed on the inner wall of the opening 51.

[0020] During detection, when the carrier plate 5 faces a tooling 2 and a car coat hanger positioned on the tooling 2 is being detected, workers can remove and install the car coat hanger on another tooling 2. In this way, the loading and unloading operation of the car coat hanger is completed during the detection process, saving time and improving the detection efficiency. During the detection process, the lifting assembly 4 drives the carrier plate 5 to descend, enabling the longitudinal clamping assembly 6 to clamp the car coat hanger so that its long side is closely attached to the tooling 2, and the transverse clamping assembly 7 makes the short side of the car coat hanger closely attached to the tooling 2, automatically completing the stable positioning of the car coat hanger, ensuring that the small holes on the car coat hanger can be directly opposite the laser detection device, enabling the small hole detection work to proceed normally, reducing the probability of the misalignment between the position of the small holes and the laser detection device, eliminating the need for manual operation, saving manpower. The CCD camera 11 is used to photograph the car coat hanger to detect whether the components installed on it are correct, and the laser sensor 8 is used for edge detection of the small holes on the car coat hanger; The lifting assembly 4 pushes the carrier plate 5 to descend, and then the longitudinal clamping assembly 6 clamps the car coat hanger, ensuring that the long side part of the car coat hanger is in contact with the inner wall of the tooling 2. Subsequently, the transverse clamping assembly 7 operates to make the short side part of the car coat hanger in contact with the inner wall of the tooling 2, ensuring that the small holes on the car coat hanger can be accurately aligned with the laser detection device. There is no need for manual operation to keep the car coat hanger stable, greatly saving manpower and improving the detection efficiency, ensuring that the laser detection of the small holes can proceed normally; The longitudinal clamping assembly 6 includes longitudinal clamping rods 61 slidably connected to the carrier plate 5 at equal intervals through sliding holes. A disc 62 is fixed to the top of the longitudinal clamping rod 61. A stabilizing sleeve 63 is fixed to the top of the carrier plate 5 corresponding to the position of the longitudinal clamping rod 61. The longitudinal clamping rod 61 is slidably connected to the inner wall of the stabilizing sleeve 63. A first spring 64 is sleeved outside the stabilizing sleeve 63. The upper end of the first spring 64 is fixed to the outer wall of the disc 62, and the lower end of the first spring 64 is fixed to the outer wall of the stabilizing sleeve 63. The bottom surface of the disc 62 abuts against the top surface of the stabilizing sleeve 63. The transverse clamping assembly 7 includes a first electric push rod 71 fixed to the middle of the top surface of the carrier plate 5. The extending end of the first electric push rod 71 is fixed with a transverse clamping plate 72, and the transverse clamping plate 72 is slidably connected to the carrier plate 5; The lifting assembly 4 operates to drive the carrier plate 5 to descend. After reaching a certain height, the bottom of the longitudinal clamping rod 61 abuts against the car coat hanger, pressing the car coat hanger against the tooling 2. After the longitudinal pressing is completed, the first electric push rod 71 operates to drive the transverse clamping plate 72 to translate, pressing the short side of the car coat hanger against the tooling 2, so as to ensure that all positions of the car coat hanger are accurately aligned, and the small holes to be detected on the car coat hanger can be directly opposite the laser detection device; The rotating assembly 3 includes a transmission rod 31 that is rotatably connected to the middle of the tooling rack 1 through a bearing and is longitudinally arranged. A motor 32 is fixed on the top surface of the tooling rack 1. The output end of the motor 32 is fixed to the top of the transmission rod 31. A rotating mounting strip 33 is fixed to the upper end of the transmission rod 31. A plurality of elastic rubber strips 19 are fixedly arranged at equal intervals from top to bottom on the lower end of the outer wall of the transmission rod 31. When it is necessary to rotate the carrier plate 5 to another automotive coat rack after the inspection of an automotive coat rack on one tooling 2 is completed, the transmission rod 31 can be rotated by driving the motor 32 to rotate. An arc-shaped sliding strip 10 is fixed to the top surface of the rotating mounting strip 33. An annular sliding rail 9 is fixed to the upper end of the tooling rack 1. The arc-shaped sliding strip 10 is slidably connected to the outer wall of the annular sliding rail 9. Moreover, the axis of the arc-shaped sliding strip 10 and the axis of the annular sliding rail 9 both coincide with the axis of the transmission rod 31. The arrangement of the arc-shaped sliding strip 10 and the annular sliding rail 9 enables the rotating mounting strip 33 to be slidably connected to the tooling rack 1; The lifting assembly 4 includes a second electric push rod 41 that is longitudinally arranged and fixed to the rotating mounting strip 33. The extending end of the second electric push rod 41 is fixed to the top surface of the carrier plate 5. Four sliding rods 42 are symmetrically fixed to the middle of the top surface of the carrier plate 5. The sliding rods 42 are slidably connected to the rotating mounting strip 33 through sliding holes. The lifting of the carrier plate 5 can be driven by driving the second electric push rod 41 to extend or contract; Since there are two toolings 2, the entire tooling has two inspection stations. While the inspection work of the automotive coat rack on one tooling 2 is in progress, workers can perform the installation positioning and removal work of the automotive coat rack on the other tooling 2. In this way, it is not necessary to perform the work of removing and reinstalling the automotive coat rack in sequence after the inspection work in the prior art and then perform the inspection. After the inspection is completed, it can quickly enter the next inspection work, improving the inspection efficiency.

[0021] Embodiment 2, please refer to Figures 7 to 9 , this embodiment provides a further technical solution based on Embodiment 1. A protective push plate 12 is slidably installed on the outer wall of one side of the tooling rack 1. A sliding frame 13 is fixed to the side of the protective push plate 12 close to the tooling rack 1. Connecting sleeves 14 are symmetrically fixed on the tooling rack 1. The sliding frame 13 is slidably connected to the inner wall of the connecting sleeve 14. A cam 15 is fixed to the lower end of the transmission rod 31. A push rod 16 is fixed to the middle of the side of the sliding frame 13 close to the cam 15. A roller 17 is rotatably installed on the side of the push rod 16 close to the cam 15. The roller 17 abuts against the outer periphery of the cam 15. Second springs 18 are symmetrically sleeved on the outside of the sliding frame 13. One end of each second spring 18 is in pressing contact with the outer wall of the sliding frame 13 and the other end is in pressing contact with the outer wall of the connecting sleeve 14; When driving the carrier plate 5 to rotate, the transmission rod 31 rotates. The rotation of the transmission rod 31 drives the cam 15 to rotate. By pushing the roller 17 with the cam 15, the sliding frame 13 drives the protective push plate 12 to move away from the tooling rack 1. If a worker is observing whether the coat rack on the tool 2 on the other side of the carrier plate 5 is installed in place, the worker can be pushed away from the rotation path of the carrier plate 5 before the carrier plate 5 rotates to the worker's position, thus protecting the worker. The elastic rubber strip 19 has the same function, reminding the worker to leave. Compared with the method of using sound and light alarms, it can avoid the problem that there is a lot of noise in the factory building, the worker observes more attentively, and cannot find the reminder in time.

[0022] Embodiment 3, please refer to Figures 10 to 12 , this embodiment provides a further technical solution based on Embodiment 1. The top of the carrier plate 5 is symmetrically and slidably connected with side push strips 20. Side push plates 21 are fixed at the mutually remote ends of the two side push strips 20. A driving frame 22 is fixed on the top of the side push strip 20. A driving column 23 is fixed on the side of the rotating mounting strip 33 close to the driving frame 22. The driving columns 23 are respectively inserted inside the two driving frames 22. When the second electric push rod 41 extends, the carrier plate 5 descends, driving the side push strips 20 to descend together. When the driving frame 22 descends and is blocked by the driving column 23, the two driving frames 22 slide towards the two sides of the carrier plate 5, so that the side push strips 20 push the side push plates 21 to slide, so as to remind the worker to leave the descending path of the carrier plate 5 through the side push plates 21 during the descending process of the carrier plate 5, further improving the safety of use.

[0023] Embodiment 4, this embodiment provides a visual inspection method for an automotive coat rack, using a visual inspection tool for an automotive coat rack, which specifically includes the following steps: A1. The worker spreads the automotive coat rack on a tool 2 for positioning; A2. The rotating assembly 3 works to rotate the carrier plate 5 above the positioned automotive coat rack, and the visual inspection assembly conducts visual inspection work on the automotive coat rack; A3. The lifting assembly 4 drives the carrier plate 5 to descend, and the longitudinal pressing assembly 6 presses multiple points of the automotive coat rack to complete the spreading and positioning, ensuring that the automotive coat rack fits the top surface of the tool 2; A4. Subsequently, the transverse pressing assembly 7 works to press the longitudinal part of the automotive coat rack against the inner wall of the tool 2, ensuring that the round holes on the longitudinal part of the automotive coat rack are aligned with the laser detection device.

[0024] In summary, the present application solves the problem in the prior art that in order to ensure that the small holes on the automotive coat hanger are directly facing the laser detection device during detection, manual labor is required to continuously maintain the stability of the automotive coat hanger, resulting in a large manual labor intensity for detection. It greatly saves manpower and improves the detection efficiency. Moreover, by setting two detection stations, during the detection process, the unloading of the tested automotive coat hanger and the loading of the automotive coat hanger to be tested can be carried out synchronously, further improving the detection efficiency.
