[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] This utility model provides a hinge testing device for testing a product 40. The product 40 includes a first connecting part 41 and a second connecting part 42 rotatably connected by a hinge. Figure 1 and Figure 2 As shown,

[0051] like Figure 2 As shown, the flipping mechanism 20 includes a driving member 21 and a flipping bracket 22. The first end of the flipping bracket 22 is connected to the driving member 21, and the second end of the flipping bracket 22 is provided with a flipping chuck. The driving member 21 is used to drive the flipping bracket 22 to rotate around the first axis as the rotation center, so that the flipping chuck flips the second connecting part 42 of the product 40 to a preset angle with the first connecting part 41. After the second connecting part 42 is flipped to a preset angle with the first connecting part 41, the driving member 21 also drives the flipping bracket 22 to apply a preset flipping force to the second connecting part 42.

[0052] like Figure 1 As shown, the visual inspection module 30 is disposed on one side of the support mechanism 10 and is used to detect whether the preset angle changes after the second connecting part 42 is subjected to a preset flipping force.

[0053] In this technical solution, during use, the first connecting part 41 of the product 40 is first placed and fixed on the bearing mechanism 10. At this time, the first connecting part 41 and the second connecting part 42 are in a 180° open state, and the second connecting part 42 is clamped in the flipping chuck. The flipping mechanism 20 is activated, and the driving component 21 drives the flipping bracket 22 to rotate in the first direction around the first axis as the rotation center (rotation direction as follows). Figure 2 As shown, the second connecting part 42 is rotated to a preset angle with the first connecting part 41. After the second connecting part 42 and the first connecting part 41 reach the preset angle, the driving member 21 continues to drive the rotating bracket 22 to apply a preset rotating force to the second connecting part 42. The vision inspection module 30 detects whether the preset angle has changed after the preset rotating force has been applied to the second connecting part 42. The first axis can be parallel to the axis of the rotating bracket 22. In the above technical solution, through the coordinated work of the bearing mechanism 10, the rotating mechanism 20 and the vision inspection module 30, this hinge inspection device can automatically detect the hinge condition to improve inspection efficiency and accuracy.

[0054] In a specific embodiment, the preset angle can be 105°, and the preset flipping force is 0.3N. In some products 40, 105° is the hovering angle. The product 40 can be placed on the bearing mechanism 10 using a robotic arm or manually, and then the hinge detection equipment can be used to detect the product 40. After the detection is completed, the driving component 21 drives the second connecting part 42 to rotate in the second direction around the first axis as the rotation center. After rotating to a certain angle, the first connecting part 41 is disengaged from the bearing mechanism 10, and the product 40 is removed. The first direction and the second direction are opposite directions. Preferably, the driving component 21 is a servo motor, and the flipping mechanism 20 also includes a reducer. The reducer can reduce the speed, amplify the torque, and improve the transmission accuracy and stability. When the servo motor and the reducer work together, they achieve high-precision, high-torque power transmission, meeting the motion control requirements of the hinge detection equipment.

[0055] In one of the alternative technical solutions, such as Figure 2 and Figure 3 As shown, in order to quickly fix the first connecting part 41, the bearing mechanism 10 includes: a positioning fixture 11 and a vacuum nozzle 12;

[0056] The positioning fixture 11 has a positioning area for supporting the first connecting part 41. The positioning area has a suction nozzle through hole extending along the thickness of the positioning fixture 11. A vacuum nozzle 12 is installed in the suction nozzle through hole. The suction end of the vacuum nozzle 12 is used to suction and fix the first connecting part 41. The connecting end of the vacuum nozzle 12 is connected to a negative pressure system. The negative pressure system may include a vacuum generator.

[0057] In the above technical solution, after the first connecting part 41 is placed in the positioning area, the first connecting part 41 is fixed by adsorption end of vacuum nozzle 12, so that the first connecting part 41 remains fixed during the detection process, thereby improving the detection accuracy.

[0058] In one of the alternative technical solutions, Figure 3 and Figure 4 As shown, the bearing mechanism 10 also includes: a locking assembly 13;

[0059] The locking assembly 13 includes a cylinder 131 and a locking rod 132. The driving end of the cylinder 131 is connected to the first end of the locking rod 132, and the second end of the locking rod 132 is constructed as a T-shaped end.

[0060] The positioning fixture 11 also has a through hole extending along its thickness, and the first connecting part 41 has a first waist-shaped through hole;

[0061] The length of the first waist-shaped through hole is greater than the length of the longitudinal section of the T-shaped end, and the width is less than the length of the longitudinal section of the T-shaped end, so that the T-shaped end can pass through the through hole and the first waist-shaped through hole in sequence to lock or release the first connecting part 41 located in the positioning area.

[0062] In the above technical solution, when it is necessary to lock the first connecting part 41 located within the positioning area, the cylinder 131 drives the locking rod 132 to rotate first, and then drives the locking rod 132 to move axially downward, so that the T-shaped end of the locking rod 132 locks the first connecting part 41 (at this time, the longitudinal section direction of the T-shaped end intersects with the width direction of the first waist shape, such as...). Figure 5 As shown, if it is necessary to release the first connecting part 41, drive the locking rod 132 to rotate until the length direction of the T-shaped end is consistent with the length direction of the first waist-shaped through hole, and the first connecting part 41 can be dislodged from the T-shaped end.

[0063] To optimize the above technical solution, the through hole of the positioning fixture 11 is a second waist-shaped through hole. The shape and size of the first waist-shaped through hole and the second waist-shaped through hole are the same, so that the T-shaped end can pass through the second waist-shaped through hole and the first waist-shaped through hole in sequence to lock or release the first connecting part 41 located in the positioning area.

[0064] In one of the alternative technical solutions, such as Figure 6 and Figure 7 As shown, the flipping chuck includes a first side arm 221 and a second side arm 222;

[0065] The first side arm 221 and the second side arm 222, which are arranged at intervals, are respectively connected to the second end of the flipping bracket 22 to construct the flipping chuck into a U-shaped chuck. The interval between the first side arm 221 and the second side arm 222 forms a flipping space. The flipping space is used to accommodate the second connecting part 42 and is driven by the driving member 21 to flip the second connecting part 42 relative to the first connecting part 41.

[0066] In the above technical solution, the edge portion of the second connecting part 42 away from the first connecting part 41 is engaged in the flipping space. When the flipping bracket 22 rotates (rotation direction as shown in the image), Figure 2 As shown), the first surface of the second connecting part 42 abuts against the second side arm 222 and rotates in the first direction with the second side arm 222 to perform the corresponding test; after the test is completed, the flip bracket 22 rotates in the second direction, the second surface of the second connecting part 42 abuts against the first side arm 221 and rotates in the second direction with the first side arm 222, and after rotating to the predetermined position, the product 40 is taken away.

[0067] In one alternative technical solution, the hinge detection device also includes a pressure sensor;

[0068] A pressure sensor is disposed on the first side arm 221 and configured to abut against the product 40; and / or,

[0069] A pressure sensor is located on the second side arm 222 and is configured to interact with the product 40.

[0070] In the above technical solutions, such as Figure 6 and Figure 7 As shown, a pressure sensor can detect the force applied to the product 40 by the first side arm 221 and the second side arm 222, thereby improving the accuracy of the detection results. In one specific embodiment, the pressure sensor is located at the part where the second side arm 222 abuts against the product 40. When the second connecting part 42 flips to a preset angle with the first connecting part 41, the flipping mechanism 20 continues to drive the second side arm 222 to apply a preset flipping force to the second connecting part 42. This preset flipping force is detected by the pressure sensor. In one embodiment, the pressure value detected by the pressure sensor is compared with the preset flipping force value to ensure the accuracy of the detection results.

[0071] Optimize the above technical solutions, such as Figure 7 As shown, a first protrusion is provided on the side of the first side arm 221 facing the second side arm 222, and a second protrusion is provided on the side of the second side arm 222 facing the first side arm 221.

[0072] The first protrusion and the second protrusion are respectively used to abut against the opposite sides of the second connecting part 42 located in the flipping space.

[0073] In the above technical solution, the gap between the first protrusion and the second protrusion is smaller than that between the first side arm 221 and the second side arm 222, which better enables the second connecting part 42 to achieve a flipping fit.

[0074] In one of the alternative technical solutions, such as Figure 8 As shown, the supporting mechanism 10 also includes: a lead screw assembly; the lead screw assembly includes: a motor 14, a lead screw, and a base 15;

[0075] The output shaft of motor 14 is connected to a lead screw drive, and the lead screw is driven to the bottom surface of base 15 so that base 15 is subjected to the helical force of the lead screw and moves linearly along the axis of the lead screw; wherein, the first axis is perpendicular to the axis of the lead screw.

[0076] The base has a positioning fixture 11 on its front side.

[0077] In the above technical solution, the motor 14 starts, driving the lead screw to rotate. Through the dynamic engagement between the lead screw and the base 15, the rotational motion of the motor 14 is converted into linear motion. When it is necessary to move the positioning fixture 11 to a corresponding position, the motor 14 is started, allowing the positioning fixture 11, which is located on the front of the base 15, to move to the preset position. It should be noted that the bottom surface of the base 15 is provided with a nut that engages with the lead screw. The screw and the nut form a helical pair, realizing the conversion between rotational motion and linear motion. Preferably, the motor 14 is a servo motor.

[0078] In an alternative technical solution, the lead screw assembly also includes: a guide rail 16;

[0079] The extension direction of the guide rail 16 is consistent with the extension direction of the lead screw. The bottom surface of the base is provided with a slider that cooperates with the guide rail. The guide rail 16 improves the positional accuracy and smoothness of the lead screw transmission. Preferably, the lead screw assembly also includes a photoelectric sensor and a light-blocking plate. The combined use of the photoelectric sensor and the light-blocking plate enables the base 15 to reach a preset position.

[0080] In an alternative technical solution, the hinge testing device also includes a support component 50 for support, such as... Figure 1 As shown.

[0081] In one optional technical solution, the visual inspection module 30 includes: a detection module and an image processing module; the detection module includes: a light source 31, a lens 32 and a CCD 33; wherein the CCD 33 is a charge-coupled device used to convert light signals into electrical signals;

[0082] Light source 31 illuminates product 40 located on support mechanism 10;

[0083] The lens 32 is positioned between the light source 31 and the CCD 33 to capture the relative positions of the first connecting part 41 and the second connecting part 42 and project the image onto the CCD 33.

[0084] The image processing module is used to receive the image uploaded by CCD33 and judge whether the product 40 has deviated from the image. The image includes a first image and a second image. The first image is the image when the first connecting part 41 and the second connecting part 42 are at a preset angle. The second image is the image of the relative position of the first connecting part 41 and the second connecting part 42 after the first connecting part 41 and the second connecting part 42 are at a preset angle and the flipping chuck applies a preset flipping force to the second connecting part 42 under the drive of the driving member 21.

[0085] In the above technical solution, in order to avoid dim lighting in the working environment, the light source 31 is turned on, the lens 32 captures the first image and the second image, and uploads them to the image processing module via the CCD 33. The processing module records the first angle between the first connecting part 41 and the second connecting part 42 in the first image, records the second angle between the first connecting part 41 and the second connecting part 42 in the second image, and determines whether the preset angle has changed by comparing the first angle and the second angle; wherein the first angle is the preset angle.

[0086] In one of the alternative technical solutions, such as Figure 2 As shown, there are two sets of detection modules, which are symmetrically arranged on the first and second sides of the product 40.

[0087] One set of detection modules uses lenses 32 to capture images of the relative positions of the first connecting part 41 and the second connecting part 42 on the first side, while another set of detection modules uses lenses 32 to capture images of the relative positions of the first connecting part 41 and the second connecting part 42 on the second side.

[0088] In one embodiment, the first connecting portion 41 of the product 40 is a first panel, and the first connecting portion 42 is a second panel.

[0089] In the above technical solution, specifically, the area corresponding to the first side can be referred to... Figure 2 The left virtual image box area, and the corresponding area on the second side can be referenced. Figure 2 The right-side virtual image box area; when in use, different detection modules can be used to detect different areas to improve detection efficiency.
