Description

Technical Field

[0001] This utility model relates to the field of automotive inspection tools, and in particular to a main carpet assembly inspection tool. Background Technology

[0002] Car floor mats are decorative pieces installed on the floor of a car's passenger compartment, offering some noise reduction. The shape of the car floor mat matches the shape of the passenger compartment floor. To ensure a better fit after installation and for ease of manufacturing, car floor mats are molded as a single piece. This means the floor mat is not pieced together in sections, maintaining the overall integrity of the space. The contour of this one-piece car floor mat matches the shape of the passenger compartment floor, ensuring a better fit.

[0003] After the main carpet is cut, the cutting accuracy needs to be tested, that is, the positional and dimensional accuracy of the main carpet cutting and hole cutting needs to be tested using a fixture. However, existing fixtures only test the position through mechanical structure. For example, the automotive floor carpet assembly accuracy testing device disclosed in CN220489938U discloses the mechanical structure of the profile fixture, seat surface fixture, and foot surface fixture for testing. However, this testing structure makes it difficult to put the integrated main carpet into the cavity of the testing fixture, and it does not have the function of positioning and testing the accuracy of the hole cutting on the main carpet. At the same time, the accuracy of the front and rear door sills and instrument panel positions needs to be considered when installing the main carpet. This testing device cannot simulate this situation. Moreover, this fixture can only be adapted to one type of automotive main carpet. Different fixtures are required for different main carpet models, resulting in poor applicability. Therefore, this utility model proposes a main carpet assembly fixture to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to propose a main carpet assembly inspection fixture. This fixture, by setting an adjustable clamping structure, facilitates the loading and unloading of the main carpet, avoiding mechanical obstruction of its placement. An extended inspection mechanism allows for simulated inspection of instrument panel and front and rear door sill positions as needed. Furthermore, it allows for quick replacement of corresponding positioning fixtures and inspection simulation blocks for different models of automotive main carpets, thus expanding its adaptability. Through a detection camera in conjunction with the main controller, visual inspection is used to automatically detect and determine the accuracy of the main carpet's outer edge and central opening position.

[0005] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a main carpet assembly inspection fixture, including an inspection table, an adjusting pressing mechanism, an extended inspection mechanism, an upper frame, an industrial inspection camera, and a main controller. The adjusting pressing mechanism is symmetrically arranged on the inspection table. An upper frame is fixedly arranged above the inspection table. An industrial inspection camera is arranged at the center of the lower side of the upper frame for automated high-precision inspection through machine vision. A main controller is arranged on one side of the upper frame for adjusting and controlling the inspection program and visually viewing the inspection image. A positioning fixture is detachably arranged on the inspection table via positioning columns for easy quick mold change. The extended inspection mechanism includes an avoidance opening slot, a lifting cylinder, a lifting seat, multi-segment push rods, an instrument simulation block, and a sill simulation block. Avoidance opening slots are symmetrically arranged on one side and the front and rear sides of the inspection table. A lifting seat is symmetrically arranged below the inspection table via a lifting cylinder. An instrument simulation block and a sill simulation block are arranged on the lifting seat via multi-segment push rods.

[0006] A further improvement is made in that: the adjusting pressing mechanism includes a sliding rail, a sliding column, a through groove, a telescopic plate, a pressing rod, and a fixed pressure plate. A sliding rail is fixedly installed on the outside of the clearance opening groove on the inspection table. A sliding column is slidably installed on the sliding rail. A telescopic plate is installed on the sliding column through the through groove. The telescopic plate is slidably adapted to the through groove. A fixed pressure plate is installed at the front end of the telescopic plate through the pressing rod. The telescopic end of the pressing rod is set downwards, and the fixed pressure plate is set at the telescopic end of the pressing rod.

[0007] A further improvement is that locking bolts are provided through the top and bottom of the sliding column. The locking bolts are respectively locked and adapted to the sliding track and the telescopic plate for adjusting and locking the downward fixed position, so as to avoid the downward structure blocking the opening position on the main carpet and affecting the detection.

[0008] Further improvements include: the lifting seat and the clearance opening slot are correspondingly adapted; after the lifting seat is raised, its upper side is flush with the surface of the positioning fixture; the telescopic end of the multi-segment push rod is horizontally oriented towards the positioning fixture and is provided with a mounting plate; the instrument simulation block and the sill simulation block are detachably installed with the mounting plate, which facilitates the replacement of the instrument simulation block and the sill simulation block for the main carpet of different vehicle models.

[0009] A further improvement is that: the instrument simulation block is located on the lifting seat on the left side of the positioning fixture, the threshold simulation block is located on the lifting seat on the front and rear sides of the positioning fixture, and the lower sides of the instrument simulation block and the threshold simulation block are slidably adapted to the upper surface of the lifting seat.

[0010] A further improvement is that an alarm indicator light is also provided on the upper side of the upper frame. The industrial inspection camera and the alarm indicator light are electrically connected to the main controller. When a failure occurs during inspection, the main controller controls the alarm indicator light to sound an alarm.

[0011] The beneficial effects of this utility model are as follows: By setting an adjustable pressing structure, this utility model can facilitate the loading and unloading of the main carpet, avoiding mechanical obstruction of the main carpet placement. By setting an extended detection mechanism, it can simulate the detection of instrument position and front and rear door sill positions as needed. At the same time, it can quickly change the corresponding positioning gauges and detection simulation blocks according to different models of automotive main carpets, thus improving the adaptability. By using a detection camera in conjunction with the main controller, it can automatically detect and judge the accuracy of the outer edge and center opening position of the main carpet using visual detection, without the need for manual observation and judgment, which is very convenient and fast.

The positioning fixture 6 is detachably arranged on the inspection table 1 through the positioning column 5 for quick mold change. The extended inspection mechanism includes an avoidance opening slot 7, a lifting cylinder 8, a lifting seat 9, a multi-segment push rod 10, an instrument simulation block 11, and a threshold simulation block 12. The avoidance opening slot 7 is symmetrically arranged on one side and the front and rear sides of the inspection table 1. The lifting seat 9 is symmetrically arranged below the inspection table 1 through the lifting cylinder 8. The instrument simulation block 11 and the threshold simulation block 12 are arranged on the lifting seat 9 through the multi-segment push rod 10, which can realize multi-functional positioning inspection simulation and has a wide range of applications.

[0018] The adjusting pressing mechanism includes a sliding rail 13, a sliding column 14, a through groove 15, a telescopic plate 16, a pressing rod 17, and a fixed pressure plate 18. The sliding rail 13 is fixedly installed on the outside of the clearance opening groove 7 on the inspection table 1. The sliding column 14 is slidably installed on the sliding rail 13. The telescopic plate 16 is installed on the sliding column 14 through the through groove 15. The telescopic plate is slidably adapted to the through groove. The front end of the telescopic plate 16 is provided with a fixed pressure plate 18 through the pressing rod 17. The telescopic end of the pressing rod is set downwards, and the fixed pressure plate is set at the telescopic end of the pressing rod.

[0019] Locking bolts 19 are provided at the top and bottom of the sliding column 14. The locking bolts 19 are respectively locked to the sliding track 13 and the telescopic plate 16 for adjusting and locking the downward fixed position, so as to avoid the downward structure blocking the opening position on the main carpet and affecting the inspection.

[0020] The lifting seat 9 is adapted to the clearance opening slot 7. After the lifting seat 9 is raised, its upper side is flush with the surface of the positioning fixture 6. The telescopic end of the multi-segment push rod 10 is horizontally oriented towards the positioning fixture 6 and is provided with a mounting plate 20.

[0024] During inspection, the positioning and fitting image of the main carpet is obtained through an industrial inspection camera, and the range markings in the image are used to determine whether the cutting and hole-cutting are qualified. If they are not qualified, an alarm light will be issued to indicate that they are qualified. If they are qualified, the fixing plate will be released and the main carpet will be removed for the next set of inspections.

[0025] When it is necessary to change to a different model of main carpet for testing, remove the positioning gauge and replace it with a new positioning gauge. Then select another program. During the first test, the position of the pressing mechanism needs to be moved and adjusted to avoid the hollowed-out position. Finally, the automatic test can be performed.
