Description

Technical Field

[0001] This utility model relates to the field of workpiece inspection technology, and in particular to a multi-station workpiece buckle inspection device. Background Technology

[0002] This multi-station workpiece buckle detection device is used to detect the installation of buckles at various positions on the workpiece, so as to determine whether the buckle installation position is accurate and whether there are any omissions in the buckle installation.

[0003] In the prior art, visual inspection is performed by moving a robot carrying a camera. The workpiece in this application has 20 clips, and each clip needs to be inspected individually. The robot carrying the camera needs to move 20 times to inspect one clip at a time, which involves locking the operation, affecting the inspection efficiency, and is easily affected by the rough edges of the product, leading to inspection failure. Since the camera is on the robot's head, the robot needs to make some large movements, and the camera cable is prone to fatigue damage, resulting in communication failure. Therefore, this application provides a multi-station workpiece clip inspection device.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-station workpiece buckle detection device, which realizes the detection of all buckles on the workpiece being installed in place or missing in one go. The detection is completed within 1 second, which significantly improves work efficiency. Since the laser displacement is a fixed installation method, there is no risk of wire fatigue, and the buckles can be directly detected. The burrs on the product have no impact on the detection.

[0006] To achieve the above objectives, this utility model provides a multi-station workpiece buckle detection device, which is used to detect buckles installed at various positions on a workpiece, and includes:

[0007] The testing table is equipped with a workpiece mounting base for placing the workpiece via a mounting platform;

[0008] A finger-shifting cylinder assembly is installed on the outside of the workpiece mounting base. The finger-shifting cylinder assembly is used to fix the workpiece placed on the workpiece mounting base.

[0009] Multiple laser displacement detection mechanisms are fixed on the detection table, and each laser displacement detection mechanism corresponds to the position of the buckle on the workpiece to realize the installation detection of the buckle.

[0010] Specifically, when inspecting the clips at various positions on the workpiece, the workpiece is placed on the workpiece mounting base, and then the workpiece is fixed by the workpiece mounting base and the finger cylinder assembly on it. Then, the laser displacement detection mechanism detects each clip. Specifically, the laser photoelectric sensor of the laser displacement detection mechanism hits the lower edge of the clip. Since there is a height difference between the clip and the workpiece mounting base, the presence and proper installation of the clip are detected by detecting this height difference. Specifically, if the clip is set as the current zero point, when no clip is installed or the clip is not installed properly, the laser displacement detection mechanism will detect a distance of 3mm. By setting an intermediate threshold of 1.5, when the detection value is greater than 1.5, it is displayed as NG, and less than 1.5 is OK.

[0011] It enables the one-time detection of all buckles installed in place or missing on the workpiece, and the detection is completed within 1 second, which significantly improves work efficiency. Since laser displacement is a fixed installation method, there is no risk of wire fatigue, and it can directly detect buckles. Product burrs have no impact on the detection.

[0012] In one embodiment of this utility model, the workpiece mounting base includes multiple workpiece supports, all of which are mounted on the inspection table via support frames. Each workpiece support has a mounting groove formed on it to fit the workpiece, and its outer side also has a slot for use with a pneumatic cylinder assembly. By configuring the workpiece mounting base as a combination of multiple workpiece supports, adjustments can be made to the workpiece supports to meet different inspection needs, making it more convenient to use. Furthermore, if a single workpiece support malfunctions, it can be directly replaced without replacing the entire workpiece mounting base.

[0013] In one embodiment of this utility model, the finger-shifting cylinder assembly includes an electric cylinder. The electric cylinder is fixed to the outside of the workpiece mounting base via a mounting bracket. A pressure plate is rotatably connected to the top of the electric cylinder via a connecting bracket. A connecting lug is fixed to the tail end of the pressure plate. The movable end of the electric cylinder is rotatably connected to the connecting lug. Specifically, the finger-shifting cylinder assembly fixes the workpiece by driving the pressure plate to rotate via the movable end of the electric cylinder and the connecting lug, thereby fixing the workpiece on the workpiece support.

[0014] In one embodiment of this utility model, a rubber gasket is fixed to the surface of the pressure plate by connecting screws. The rubber gasket improves the stability of the workpiece on the workpiece support during the rotation of the pressure plate, preventing slippage, and also protects the workpiece surface from indentations.

[0015] In one embodiment of the present invention, the laser displacement detection mechanism includes a support rod, which is fixed to the mounting platform by a connecting seat, and a laser displacement sensor is mounted on the support rod by a combined connector.

[0016] In one embodiment of this utility model, the combined connector includes a connecting sleeve that slides onto a support rod, with a locking screw passing through the connecting sleeve. A mounting sleeve is connected to the outer side of the connecting sleeve via a damping shaft, and the laser displacement sensor is fixed within the mounting sleeve. The height of the laser displacement sensor can be adjusted by sliding the connecting sleeve on the support rod, and it is fixed by the locking screw. The mounting sleeve is rotated via the damping shaft, thereby causing the laser displacement sensor to rotate. This allows for arbitrary adjustment of the laser displacement sensor's height and angle, improving detection flexibility and making it more convenient to use.

[0017] In one embodiment of this utility model, a stand is vertically fixed on the testing platform, and a monitoring camera is installed on the stand. Multiple stands are provided, evenly spaced. After the testing is completed, the monitoring camera takes and records the images.

[0018] Compared with the prior art, the multi-station workpiece buckle detection device according to this utility model can detect all buckles on the workpiece in place or missing in one go. The detection is completed within 1 second, which significantly improves work efficiency. Since the laser displacement is a fixed installation method, there is no risk of wire fatigue, and the buckles can be directly detected. The burrs on the product have no impact on the detection.

[0019] By configuring the workpiece mounting base as a combination of multiple workpiece support seats, the workpiece support seats can be adjusted according to different types of inspection needs, making it more convenient to use. Furthermore, when a single workpiece support seat fails, it can be directly replaced without replacing the entire workpiece mounting base.

[0020] The height of the laser displacement sensor can be adjusted by sliding the connecting sleeve on the support rod, and it is fixed by the locking screw. The mounting sleeve can be rotated by the damping shaft, thereby driving the laser displacement sensor to rotate. This allows for arbitrary adjustment of the height and angle of the laser displacement sensor, improving the flexibility of detection and making it more convenient to use.

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0028] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0029] like Figure 1-5 As shown, a multi-station workpiece buckle detection device according to a preferred embodiment of the present invention is used to detect buckles 51 installed at various positions on a workpiece 5, and includes:

[0030] Inspection table 1, the inspection table 1 is equipped with a workpiece mounting seat 20 for placing workpiece 5 via mounting table 2;

[0031] A finger-shifting cylinder assembly 3 is installed on the outside of the workpiece mounting base 20. The finger-shifting cylinder assembly 3 is used to fix the workpiece 5 placed on the workpiece mounting base 20.

[0032] Multiple laser displacement detection mechanisms 4 are fixed on the detection table 1. Each laser displacement detection mechanism 4 corresponds to the position of the buckle 51 on the workpiece 5, so as to realize the installation detection of the buckle 51.

[0033] Specifically, when inspecting the clips 51 at various positions on the workpiece 5 to be inspected, the workpiece 5 is placed on the workpiece mounting base 20, and then the workpiece 5 is fixed by the workpiece mounting base 20 in conjunction with the finger cylinder assembly 3 on it. Then, the laser displacement detection mechanism 4 inspects each clip 51. Specifically, the laser photoelectric sensor of the laser displacement detection mechanism 4 hits the lower edge of the clip 51. Since there is a height difference between the clip 51 and the workpiece mounting base 20, the presence and proper installation of the clip are detected by detecting this height difference. Specifically, if the clip 51 is set as the current zero point, when the clip 51 is not installed or is not installed properly, the laser displacement detection mechanism 4 will detect a distance of 3mm. By setting an intermediate threshold of 1.5, when the detection value is greater than 1.5, it is displayed as NG, and less than 1.5 is OK.

[0034] It enables the one-time detection of all buckles installed in place or missing on the workpiece, and the detection is completed within 1 second, which significantly improves work efficiency. Since laser displacement is a fixed installation method, there is no risk of wire fatigue, and it can directly detect buckles. Product burrs have no impact on the detection.

[0035] Specifically, such as Figure 2 As shown, in this embodiment, the workpiece mounting base 20 includes multiple workpiece support seats 21. All workpiece support seats 21 are mounted on the inspection table 1 via support frames. Each workpiece support seat 21 has a mounting groove 22 formed on it to fit the workpiece 5. The outer side of each workpiece support seat 21 also has a slot 23 for use with the finger-shifting cylinder assembly 3. By configuring the workpiece mounting base 20 as a combination of multiple workpiece support seats 21, adjustments can be made to the workpiece support seats 21 according to different types of inspection needs, making it more convenient to use. Furthermore, when a single workpiece support seat 21 malfunctions, it can be directly replaced without replacing the entire workpiece mounting base 20.

[0036] Specifically, such as Figure 3 As shown, in this embodiment, the finger-shifting cylinder assembly 3 includes an electric cylinder 32. The electric cylinder 32 is fixed to the outside of the workpiece mounting base 20 via a mounting bracket 31. A pressure plate 35 is rotatably connected to the top of the electric cylinder 32 via a connecting bracket 33. A connecting ear 34 is fixed to the tail end of the pressure plate 35. The movable end of the electric cylinder 32 is rotatably connected to the connecting ear 34. Specifically, the finger-shifting cylinder assembly 3 fixes the workpiece 5 by driving the pressure plate 35 to rotate through the movable end of the electric cylinder 32 in conjunction with the connecting ear 34. The rotation of the pressure plate 35 fixes the workpiece 5 on the workpiece support 21.

[0037] A rubber gasket 36 is fixed to the surface of the pressure plate 35 by connecting screws. The rubber gasket 36 improves the stability of the workpiece 5 on the workpiece support 21 when the pressure plate 35 rotates, prevents slippage, and protects the surface of the workpiece 5 to prevent indentation.

[0038] Specifically, such as Figure 4 As shown, in this embodiment, the laser displacement detection mechanism 4 includes a support rod 41, which is fixed on the mounting platform 2 by a connecting seat 42. A laser displacement sensor 47 is mounted on the support rod 41 by a combined connector.

[0039] In one embodiment of this utility model, the combined connector includes a connecting sleeve 43 slidably sleeved on the support rod 41, with a locking screw 44 penetrating through the connecting sleeve 43. A mounting sleeve 46 is connected to the outside of the connecting sleeve 43 via a damping shaft 45, and a laser displacement sensor 47 is fixed in the mounting sleeve 46. The height of the laser displacement sensor 47 can be adjusted by sliding the connecting sleeve 43 on the support rod 41, and fixed by the locking screw 44. The mounting sleeve 46 can be rotated via the damping shaft 45, thereby causing the laser displacement sensor 47 to rotate. This allows for arbitrary adjustment of the height and angle of the laser displacement sensor 47, improving detection flexibility and making it more convenient to use.

[0040] Specifically, such as Figure 1 As shown, in this embodiment, a stand 11 is vertically fixed on the testing platform 1, and a monitoring camera 12 is installed on the stand 11. Multiple stands 11 are provided, and the stands 11 are evenly spaced. After the testing is completed, the monitoring camera 12 takes and stores the images.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
