[0078] Please refer to Figure 4。Embodiments of the present application provide an angle detection device for automatically detecting the opening angle of a workpiece 1 to be measured.

[0079] Figure 1 and Figure 2 are the front view and top view of a workpiece 1 to be measured provided in this embodiment. Figure 3 is a schematic diagram of the workpiece 1 to be measured after the second workpiece 102 is flipped relative to the first workpiece 101.

[0080] As Figure 1 and Figure 2 shown, the workpiece 1 to be measured is a box for placing a Bluetooth headset. The workpiece 1 to be measured includes a first workpiece 101 and a second workpiece 102 that are hinged to each other. Specifically, the first workpiece 101 and the second workpiece 102 are hinged by a hinge shaft 103. The first workpiece 101 and the second workpiece 102 can rotate relative to each other around the axis of the hinge shaft 103. In the initial posture shown in Figure 1 , a cavity 104 is formed between the first workpiece 101 and the second workpiece 102.

[0081] As Figure 3 shown, the second workpiece 102 is flipped relative to the first workpiece 101, so as to have an opening angle. An elastic component can be provided between the first workpiece 101 and the second workpiece 102 for maintaining the opening angle.

[0082] The angle detection device provided by the present application can automatically detect the above-mentioned opening angle.

[0083] Figure 4 is the top view of an embodiment of the angle detection device of the present application.

[0084] As Figure 4 shown, the angle detection device includes a loading component 2, a flipping component 3, and a detection component 4. The loading component 2 is used to fix the first workpiece 101. The flipping component 3 is arranged on one side of the loading component 2 and is used to drive the second workpiece 102 to flip relative to the first workpiece 101, so that the second workpiece 102 has an opening angle relative to the first workpiece 101. The detection component 4 is arranged on one side of the loading component 2 and is used to detect the opening angle. The detection component 4 and the flipping component 3 are located on the same side or different sides of the loading component 2, and the present application does not limit this.

[0085] The angle detection device provided by the embodiments of the present application has a simple structure. The angle detection device fixes the first workpiece 101 of the workpiece 1 to be measured through the loading component 2, drives the second workpiece 102 to flip relative to the first workpiece 101 through the flipping component 3 to form an opening angle, and then detects the opening angle through the detection component 4. Thus, the angle detection device can automatically detect the opening angle of the second workpiece 102 relative to the first workpiece 101 without manual assistance.

[0086] In addition, since the angle detection device can automatically detect the opening angle, it has the advantages of high detection efficiency and high accuracy.

[0087] The flip assembly 3 is described in detail below.

[0088] Figure 5 It is a front view of a flip assembly 3 provided in this embodiment. Figure 6 for Figure 5 Left view of . Figure 7 for Figure 5 A top view of the Figures 5 to 7 As shown, the flip assembly 3 includes a toggle member 31 and a first power member 33 .

[0089] The toggle member 31 is used to contact the second workpiece 102. When the toggle member 31 contacts the second workpiece 102, the toggle member 31 can flip the second workpiece 102 relative to the first workpiece 101. Preferably, the contact point between the toggle member 31 and the second workpiece 102 can be a point far from the hinge shaft 103, so that the toggle member 31 applies a small force to the second workpiece 102, so that the second workpiece 102 can be flipped relative to the first workpiece 101.

[0090] In this embodiment, the flip assembly 3 may further include a first support 35 and a first rotating shaft 36. The first rotating shaft 36 is rotatably mounted on the first support 35, and the toggle member 31 is fixed to one end of the first rotating shaft 36 close to the loading assembly 2. The toggle member 31 includes a first toggle rod 311. The axis of the first toggle rod 311 is eccentrically arranged with the axis of the first rotating shaft 36, that is, the axis of the first toggle rod 311 is not colinear with the axis of the first rotating shaft 36, so that when the first rotating shaft 36 rotates, the first toggle rod 311 can drive the second workpiece 102 to flip relative to the first workpiece 101.

[0091] The first power member 33 is used to drive the toggle member 31 to drive the second workpiece 102 to flip. The first power member 33 can be a motor fixed to the first support 35. The rotating end of the motor is connected to the end of the first rotating shaft 36 away from the loading assembly 2. In this embodiment, the motion trajectory of the toggle member 31 is an arc. In other embodiments, the motion trajectory of the toggle member 31 can also be a straight line. In this case, the first power member 33 can be a cylinder, an electric cylinder, a linear motor, etc. It is only necessary to ensure that the toggle member 31 can be applied with a force to flip relative to the first workpiece 101.

[0092] The flipping assembly 3 may further include a fifth power member 32 for driving the toggling member 31 away from or closer to the second workpiece 102. The fifth power member 32 may be a cylinder. The cylinder block of the cylinder is fixedly provided on the second support 34. The piston rod of the cylinder is fixedly connected to the first support 35. The fifth power member 32 drives the first support 35, and the first support 35 drives the toggling member 31 away from or closer to the second workpiece 102. In other embodiments, the fifth power member 32 may also be an electric cylinder, a linear motor, etc.

[0093] The flipping assembly 3 is in an initial state at the beginning. When the second workpiece 102 needs to be flipped, the fifth power member 32 drives the first support 35 to drive the toggling member 31 closer to the second workpiece 102, and then the first power member 33 drives the first rotating shaft 36 to drive the toggling member 31 to rotate, so that the second workpiece 102 is flipped relative to the first workpiece 101. After the second workpiece 102 is flipped relative to the first workpiece 101 to the opening angle, the first power member 33 stops, and the fifth power member 32 drives the first support 35 to drive the toggling member 31 away from the second workpiece 102. Thereafter, the flipping assembly 3 returns to the initial state.

[0094] In a preferred embodiment, the first rotating shaft 36 and the hinge shaft 103 are coaxially arranged. The toggling member 31 further includes a second toggle rod 312, and the axis of the second toggle rod 312 is also eccentrically arranged with respect to the axis of the first rotating shaft 36, that is, the axis of the second toggle rod 312 is not collinear with the axis of the first rotating shaft 36. When the toggling member 31 contacts the second workpiece 102, the second workpiece 102 is located between the first toggle rod 311 and the second toggle rod 312. The fifth power member 32 can drive the first toggle rod 311 and the second toggle rod 312 to move, so that the second workpiece 102 is located between the first toggle rod 311 and the second toggle rod 312, and then the first power member 33 drives the first toggle rod 311 and the second toggle rod 312 to rotate around the first rotating shaft 36, thereby driving the second workpiece 102 to flip a certain angle. Since an elastic component is provided between the first workpiece 101 and the second workpiece 102, under the action of this elastic component, the second workpiece 102 will be rotated to the corresponding opening angle.

[0095] The loading assembly 2 will be introduced in detail below.

[0096] Figure 8 This is the front view of a loading assembly 2 provided in this embodiment. Figure 9 For Figure 8 the right view. Figure 10 For Figure 8 the top view. As Figures 8 to 10 shown, the loading assembly 2 includes a base 21, a first positioning portion 22, a second positioning portion 23, a first moving member 24, and a second moving member 25.

[0097] The base 21 has a bearing surface for bearing the first workpiece 101. The first positioning portion 22 and the second positioning portion 23 are fixed to the base 21 and protrude from the bearing surface. The first positioning portion 22 is used to position the first workpiece 101 in the first direction X, and the second positioning portion 23 is used to position the first workpiece 101 in the second direction Y. The first moving member 24 is slidably connected to the base 21 in the first direction X and can approach or move away from the first positioning portion 22. The second moving member 25 is slidably connected to the base 21 in the second direction Y and can approach or move away from the second positioning portion 23. Here, the sliding connection can adopt a linear guide slider structure 8 or other sliding connection methods, and the present application does not make a unique limitation on this. The first direction X and the second direction Y intersect. In this embodiment, the first direction X and the second direction Y are perpendicular and both parallel to the bearing surface. More specifically, in Figure 10 it, the first direction X is the horizontal direction, and the second direction Y is the vertical direction.

[0098] For Figure 4 the angle detection device shown, it can be considered that the first direction X is Figure 4 the horizontal direction in Figure 4 it, the second direction Y is Figure 4 the vertical direction in

[0099] The process of fixing the first workpiece 101 by the loading assembly 2 is as follows:

[0100] Place the first workpiece 101 on the bearing surface and make the first positioning portion 22 received in the cavity 104 of the workpiece 1 to be measured. In the first direction X, the first workpiece 101 is located between the first positioning portion 22 and the first moving member 24 and is clamped. In the second direction Y, the first workpiece 101 is located between the second positioning portion 23 and the second moving member 25 and is clamped.

[0101] In a preferred embodiment, the loading assembly 2 further includes a first elastic member 27 and a second elastic member 28. The first elastic member 27 is disposed between the first moving member 24 and the base 21 along the first direction X, and is used to apply an elastic force to the first moving member 24, so that the first moving member 24 approaches the first positioning portion 22, and further enables the first moving member 24 to elastically press against the first workpiece 101. The second elastic member 28 is disposed between the second moving member 25 and the base 21 along the second direction Y, and is used to apply an elastic force to the second moving member 25, so that the second moving member 25 approaches the second positioning portion 23, and further enables the second moving member 25 to elastically press against the first workpiece 101. The first elastic member 27 and the second elastic member 28 may be springs or other elastic elements, and the present application does not limit this. By providing the first elastic member 27 and the second elastic member 28, the first moving member 24 and the second moving member 25 can press the first workpiece 101 against the first positioning portion 22 and the second positioning portion 23 respectively in the initial state.

[0102] In this embodiment, the first moving member 24 and the second moving member 25 are in transmission cooperation to be able to move synchronously. That is, the first moving member 24 and the second moving member 25 can at least move away from the first positioning portion 22 and the second positioning portion 23 synchronously, or approach the first positioning portion 22 and the second positioning portion 23 synchronously. The loading assembly 2 further includes a second power member 29, which is used to drive the first moving member 24 away from the first positioning portion 22 and drive the second moving member 25 away from the second positioning portion 23, or is used to drive the second moving member 25 away from the second positioning portion 23 and drive the first moving member 24 away from the first positioning portion 22. In this embodiment, the second power member 29 is used to drive the first moving member 24 away from the first positioning portion 22. Specifically, the second power member 29 may be a cylinder. The cylinder body of the cylinder is fixedly provided on the base 21. The piston rod of the cylinder extends and retracts in the first direction X and acts on the connecting member 218. The connecting member 218 is slidably mounted on the base 21 in the first direction X and is fixedly connected to the first moving member 24. When the piston rod of the cylinder extends, it can drive the connecting member 218 and the first moving member 24 to move in a direction away from the first positioning portion 22. In other embodiments, the second power member 29 may also be an electric cylinder, a linear motor, etc.

[0103] Specifically, one of the first moving member 24 and the second moving member 25 has an inclined surface 26. The inclined surface 26 intersects with the first direction X and the second direction Y respectively. The loading assembly 2 further includes a roller 210 that abuts against the inclined surface 26. The roller 210 is rotatably provided on the one of the first moving member 24 and the second moving member 25 that does not have the inclined surface 26.

[0104] In this embodiment, the first moving member 24 is provided with an inclined surface 26, and the second moving member 25 is rotatably installed with a roller 210. When the second power member 29 operates to move the first moving member 24 away from the first positioning portion 22, at the same time, it drives the second moving member 25 to move away from the second positioning portion 23 synchronously.

[0105] In a preferred embodiment, in order to further improve the measurement efficiency, a plurality of loading components 2 can be provided, and the number of flipping components 3 is equal to the number of loading components 2. One flipping component 3 corresponds to one loading component 2, so that the second workpieces 102 of a plurality of workpieces to be measured 1 can be flipped simultaneously.

[0106] As Figure 5 and Figure 7 shown, the first rotating shafts 36 of a plurality of flipping components 3 can be respectively connected with a third pulley 37, and the plurality of third pulleys 37 are connected by a belt and share a first power member 33, so that only one first power member 33 needs to be provided to drive the first rotating shafts 36 of the plurality of flipping components 3 to rotate.

[0107] Furthermore, in order to improve the automation performance of the loading component 2 and enable the loading component 2 to rotate to adjust the posture of the workpiece to be measured 1 on the loading component 2 to meet different detection requirements, as Figures 8 to 12 shown, the angle detection device can further include a first mounting plate 211, a first pulley 214, a second pulley 216, a conveyor belt 217 and a third power member 215.

[0108] A plurality of loading components 2 are rotatably installed on the first mounting plate 211 at intervals along the first direction X. Specifically, the base 21 of the loading component 2 is rotatably installed on the first mounting plate 211. The first pulley 214 is fixedly arranged on the plurality of loading components 2. The second pulley 216 is rotatably installed on the first mounting plate 211. The first pulley 214 and the second pulley 216 are connected by the conveyor belt 217. The third power member 215 is used to drive the second pulley 216 to rotate. When the second pulley 216 is driven, it drives the first pulley 214 to rotate through the conveyor belt 217, thereby driving the loading component 2 to rotate.

[0109] Specifically, a bearing seat 212 and a third power member 215 are fixedly arranged on the first mounting plate 211. One end of the base 21 of the loading component 2 is fixedly connected with a second rotating shaft 213. The second rotating shaft 213 is rotatably installed in the bearing seat 212. The first pulley 214 is fixedly arranged on the second rotating shaft 213 and is coaxially arranged with the second rotating shaft 213. The third power member 215 can be a motor. The second pulley 216 is fixedly connected with the rotating end of the third power member 215. When the third power member 215 operates, it will drive the second pulley 216 to rotate, then drive the first pulley 214 to rotate through the conveyor belt 217, then drive the second rotating shaft 213 to rotate, and finally drive the loading component 2 to rotate, so as to adjust the posture of the workpiece to be measured 1.

[0110] Preferably, a second rotating shaft 213 is fixedly provided at each of the two opposite ends of the base 21 in the second direction Y. The two bearing seats 212 are fixedly arranged on the first mounting plate 211 along the second direction Y. The two second rotating shafts 213 are coaxial and are respectively rotatably mounted on the two bearing seats 212.

[0111] As Figure 4 shown, the angle detection device may further include a conveying component 5 for driving the loading component 2 to move, so that the workpiece 1 with an opening angle to be measured is conveyed to the detection area of the detection component 4. The moving end of the conveying component 5 is fixedly connected to the loading component 2. The conveying component 5 may adopt a linear motor or a motor screw nut group. Preferably, the moving direction of the moving end of the conveying component 5 is parallel to the first direction X.

[0112] In this embodiment, the first mounting plate 211 may be mounted on the moving end of the conveying component 5. The detection component 4 and the flipping component 3 are located on different sides of the conveying component 5.

[0113] In this embodiment, the detection component 4 can automatically detect the opening angle of the second workpiece 102 relative to the first workpiece 101. As Figures 13 to 14 shown, the detection component 4 includes a third support 41, a camera 42 and a light source 43. The camera 42 and the light source 43 are fixedly arranged on the third support 41. The light source 43 is located between the camera 42 and the workpiece 1 to be measured. The camera 42 can take a picture of the workpiece 1 to be measured to obtain an image of the workpiece 1 to be measured with an opening angle, so as to detect the opening angle. Specifically, the computer can detect the opening angle according to the obtained image posture.

[0114] In this embodiment, in order to further improve the measurement efficiency, the angle detection device further includes an adsorption component 6.

[0115] Figure 15 is the front view of an adsorption component 6 provided in this embodiment. Figure 16 For Figure 15 the left view. Figure 17 For Figure 15 the top view. As Figures 15 to 17 shown, the adsorption component 6 includes a second mounting plate 61, a moving plate 62, a suction cup 63, a fourth power component 64 and a third elastic component 66.

[0116] The moving plate 62 is slidably connected to the second mounting plate 61. Here, the sliding connection can adopt a linear guide slider structure 8, or other sliding connection methods. This application does not make a unique limitation on this. The moving plate 62 can move relative to the second mounting plate 61 in the third direction Z. The suction cup 63 is fixedly arranged at one end of the moving plate 62 close to the workpiece to be measured 1, and is used for adsorbing the first workpiece 101 and / or the second workpiece 102. In this embodiment, the third direction Z is the direction perpendicular to the bearing surface. More specifically, in Figure 15 and Figure 16 it, the third direction Z is the vertical direction.

[0117] The fourth power member 64 is used to drive the moving plate 62 and the suction cup 63 fixedly connected thereto to move towards the end of the second mounting plate 61 away from the workpiece to be measured 1. That is, the fourth power member 64 is used to drive the moving plate 62 and the suction cup 63 fixedly connected thereto to move upward along the third direction Z. The fourth power member 64 can be a cylinder. The cylinder block of the cylinder is fixedly arranged on the second mounting plate 61. The piston rod of the cylinder expands and contracts in the third direction Z and acts on the moving plate 62. In other embodiments, the fourth power member 64 can also be an electric cylinder, a linear motor, etc.

[0118] Both ends of the third elastic member 66 are respectively connected to the second mounting plate 61 and the moving plate 62, so as to have a buffering effect when the moving plate moves in the third direction, so that the workpiece to be measured 1 on the suction cup 63 can be smoothly placed on the bearing surface. The third elastic member 66 can be a tension spring.

[0119] Preferably, in the first direction X, a plurality of moving plates 62 are arranged at intervals on the second mounting plate 61, so as to be able to simultaneously transport a plurality of workpieces to be measured 1 to the loading assembly 2, thereby improving the feeding efficiency. The number of moving plates 62 can be equal to the number of loading assemblies 2. A limiting member 67 is fixedly arranged at the end of the moving plate 62 away from the workpiece to be measured 1, and is used to prevent the moving plate 62 from falling off the second mounting plate 61. The limiting member 67 can be a baffle.

[0120] The adsorption assembly 6 can also include a sixth power member 65, which is used to drive the second mounting plate 61 to move in the third direction Z. The sixth power member 65 can be a cylinder. The piston rod of the cylinder expands and contracts in the third direction Z and is fixedly connected to the second mounting plate 61. In other embodiments, the sixth power member 65 can also be an electric cylinder, a linear motor, etc. Among them, the sixth power member 65 can drive the second mounting plate 61 to move towards the workpiece to be adsorbed 1 along the third direction Z (that is, move downward), and the fourth power member 64 drives the moving plate 62 and the suction cup 63 fixedly connected thereto to move in the direction opposite to the moving direction of the second mounting plate 61 (that is, move upward).

[0121] Preferably, the suction cup 63 is used to adsorb the second workpiece 102. As Figure 15As shown, a pressing block 68 is further provided at one end of the movable plate 62 close to the workpiece 1 to be tested, and is used to contact the first workpiece 101. When the suction cup 63 is adsorbed to the second workpiece 102, and the adsorption assembly 6 brings the workpiece 1 to be tested above the loading assembly 2, the pressing block 68 can press the first workpiece 101 to the receiving surface of the base 21, ensuring that the first workpiece 101 and the receiving surface are in good contact and can fit together better, so that the first workpiece 101 can be fixed more stably on the bearing surface.

[0122] like Figure 4 As shown, the adsorption component 6 is slidably connected to the guide rail 7 along the first direction X, so that after adsorbing the test piece 1, the adsorption component 6 can slide along the first direction X to the top of the loading component 2 to realize the conveying of the test piece 1 to the loading component 2. The flipping component 3 and the detection component 4 are respectively located on both sides of the loading component 2 along the second direction Y. After the loading component 2 fixes the first workpiece 101, the flipping component 3 flips the second workpiece 102, and the conveying component 5 drives the loading component 2 to move, so that the test piece 1 with an opening angle is conveyed to the detection area of ​​the detection component 4, and the detection component 4 automatically detects the opening angle.
