The angle detection device fixes a first workpiece 101 of a to-be-detected piece 1 through the charging assembly 2, drives a second workpiece 102 to overturn relative to the first workpiece 101 through the overturning assembly 3 to form an opening angle, and then detects the opening angle through the detection assembly 4. Therefore, the angle detection device can automatically detect the opening angle of the second workpiece 102 with respect to the first workpiece 101 without manual operation.

The flip assembly 3 is described in detail below.

Fig. 5 is a front view of the flip assembly 3 provided in the present embodiment. Fig. 6 is a left side view of fig. 5. Fig. 7 is a top view of fig. 5. As shown in fig. 5 to 7, the flipping unit 3 includes a toggle member 31 and a first power member 33.

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 turn the second workpiece 102 relative to the first workpiece 101. Preferably, the contact point of the toggle 31 with the second workpiece 102 may be a point farther from the hinge shaft 103, so that the toggle 31 exerts a smaller force on the second workpiece 102, i.e., the second workpiece 102 can be turned over with respect to the first workpiece 101.

In the present embodiment, the flipping module 3 may further include a first support 35 and a first rotation shaft 36. The first rotating shaft 36 is rotatably mounted on the first support 35, and the toggle member 31 is fixedly mounted on one end of the first rotating shaft 36 close to the loading assembly 2. The toggle member 31 includes a first toggle lever 311. The axis of the first shift lever 311 is eccentric to the axis of the first rotating shaft 36, that is, the axis of the first shift lever 311 is not collinear with the axis of the first rotating shaft 36, so that when the first rotating shaft 36 rotates, the first shift lever 311 can drive the second workpiece 102 to turn relative to the first workpiece 101.

The first power member 33 is used for driving the toggle member 31 to drive the second workpiece 102 to turn over. The first power member 33 may be a motor fixedly mounted on the first support 35. The rotating end of the motor is in driving connection with the end of the first shaft 36 remote from the charging assembly 2. In the present embodiment, the movement locus of the toggle member 31 is a circular arc. In other embodiments, the movement track of the toggle member 31 may also be a straight line, and in this case, the first power member 33 may be an air cylinder, an electric cylinder, a linear motor, or the like. It is only necessary to ensure that a force that is turned over with respect to the first workpiece 101 can be applied to the toggle member 31.

The turnover assembly 3 may further include a fifth power member 32 for driving the toggle member 31 away from or toward the second workpiece 102. The fifth power member 32 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the second support 34. The piston rod of the cylinder is fixedly connected with the first support 35. The fifth power member 32 drives the first support 35, and the first support 35 drives the toggle member 31 to move away from or close to the second workpiece 102. In other embodiments, the fifth power component 32 can also be an electric cylinder, a linear motor, etc.

When the turning assembly 3 is in an initial state at the beginning and needs to turn over the second workpiece 102, the fifth power member 32 drives the first support 35 to drive the shifting member 31 to be close to the second workpiece 102, and then the first power member 33 drives the first rotating shaft 36 to drive the shifting member 31 to rotate, so that the second workpiece 102 turns over relative to the first workpiece 101. After the second workpiece 102 is turned over to an open angle relative to the first workpiece 101, the first power element 33 is stopped, and the fifth power element 32 drives the first support 35 to drive the toggle element 31 to move away from the second workpiece 102. Thereafter, the flip member 3 is returned to the initial state.

In a preferred embodiment, first shaft 36 and hinge shaft 103 are coaxially disposed. The toggle member 31 further includes a second toggle lever 312, and an axis of the second toggle lever 312 is also disposed eccentrically to an axis of the first rotating shaft 36, i.e., the axis of the second toggle lever 312 is not collinear with the axis of the first rotating shaft 36. When the toggle member 31 contacts the second workpiece 102, the second workpiece 102 is located between the first toggle lever 311 and the second toggle lever 312. The fifth power element 32 can drive the first driving lever 311 and the second driving lever 312 to move, so that the second workpiece 102 is located between the first driving lever 311 and the second driving lever 312, and then the first power element 33 drives the first driving lever 311 and the second driving lever 312 to rotate around the first rotating shaft 36, so as to drive the second workpiece 102 to turn over a certain angle.

The charging assembly 2 is described in detail below.

Fig. 8 is a front view of a charging assembly 2 provided in the present embodiment. Fig. 9 is a right side view of fig. 8. Fig. 10 is a top view of fig. 8. As shown in fig. 8 to 10, the charging 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.

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 separate 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 separate from the second positioning portion 23. The sliding connection may be a wire-rail slider structure 8 or other sliding connection, which is not limited in this application. 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 parallel to the bearing surface.

For the angle detection device shown in fig. 4, it can be considered that the first direction X is a horizontal direction in fig. 4, the second direction Y is a vertical direction in fig. 4, and the third direction Z is a direction perpendicular to the paper surface in fig. 4.

The process of fixing the first workpiece 101 by the charging assembly 2 is as follows:

the first workpiece 101 is placed on the bearing surface, and the first positioning portion 22 is accommodated in the cavity 104 of the object 1. In the first direction X, the first workpiece 101 is positioned between the first positioning portion 22 and the first moving member 24, and is clamped.

The second elastic element 28 is disposed between the second moving element 25 and the base 21 along the second direction Y, and is used for applying an elastic force to the second moving element 25, so that the second moving element 25 approaches the second positioning portion 23, and the second moving element 25 elastically presses the first workpiece 101. The first elastic member 27 and the second elastic member 28 may be springs or other elastic elements, which are not limited in this application. 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.

In this embodiment, the first moving member 24 is in driving engagement with the second moving member 25 so as to be capable of synchronous movement. That is, the first moving member 24 and the second moving member 25 can be at least synchronously away from the first positioning portion 22 and the second positioning portion 23, or synchronously close to the first positioning portion 22 and the second positioning portion 23. The charging assembly 2 further comprises a second power member 29 for driving the first moving member 24 away from the first positioning portion 22 and bringing the second moving member 25 away from the second positioning portion 23, or for driving the second moving member 25 away from the second positioning portion 23 and bringing the first moving member 24 away from the first positioning portion 22. In this embodiment, the second power member 29 is used for driving 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 arranged 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, the connecting member 218 and the first moving member 24 are driven to move away from the first positioning portion 22. In other embodiments, the second power member 29 may also be an electric cylinder, a linear motor, or the like.

Specifically, one of the first moving member 24 and the second moving member 25 has a slope 26. The inclined surface 26 intersects the first direction X and the second direction Y, respectively. The loading assembly 2 further comprises a roller 210 which is in abutment with the ramp 26. The roller 210 is rotatably disposed on one of the first moving member 24 and the second moving member 25, on which the inclined surface 26 is not disposed.

In a preferred embodiment, in order to further improve the measurement efficiency, a plurality of loading assemblies 2 may be provided, the number of the turnover assemblies 3 is equal to that of the loading assemblies 2, and one turnover assembly 3 corresponds to one loading assembly 2, so that the second workpieces 102 of a plurality of workpieces 1 to be measured can be turned over at the same time.

As shown in fig. 5 and 7, the first rotating shafts 36 of the plurality of turnover assemblies 3 may be respectively connected with a third belt wheel 37, and the plurality of third belt wheels 37 are connected by a belt and share a first power member 33, so that the first rotating shafts 36 of the plurality of turnover assemblies 3 can be driven to rotate only by arranging one first power member 33.

Further, in order to improve the automation performance of the charging assembly 2, the charging assembly 2 may be rotated to adjust the posture of the to-be-detected member 1 on the charging assembly 2, so as to meet different detection requirements, as shown in fig. 8 to 12, the angle detection device may 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.

The fourth power element 64 is used for driving the moving plate 62 and the suction cup 63 fixedly connected thereto to move towards one end of the second mounting plate 61 away from the object 1 to be tested. That is, the fourth power member 64 is used for driving the moving plate 62 and the suction cup 63 fixedly connected thereto to move in the third direction Z. The fourth power member 64 may be a cylinder. The cylinder body of the cylinder is fixedly arranged on the second mounting plate 61. The piston rod of the cylinder extends and contracts in the third direction Z and acts on the moving plate 62. In other embodiments, the fourth power member 64 may also be an electric cylinder, a linear motor, or the like.

The two ends of the third elastic member 66 are respectively connected to the second mounting plate 61 and the moving plate 62, so that the moving plate has a buffering effect when moving in the third direction, and the to-be-measured object 1 on the suction cup 63 can be stably placed on the bearing surface. The third elastic member 66 may be a tension spring.

Preferably, a plurality of moving plates 62 are arranged on the second mounting plate 61 at intervals in the first direction X, so that a plurality of pieces to be tested 1 can be conveyed to the loading assembly 2 at the same time, and the loading efficiency can be improved. The number of moving plates 62 may be equal to the number of loading assemblies 2. A limiting member 67 is fixedly disposed at an end of the moving plate 62 away from the to-be-tested object 1, for preventing the moving plate 62 from falling off from the second mounting plate 61. The limiting member 67 may be a baffle.

The adsorption assembly 6 may further include a sixth power member 65 for driving the second mounting plate 61 to move in the third direction Z. The sixth power member 65 may be a cylinder. The piston rod of the cylinder extends and retracts in the third direction Z and is fixedly connected with the second mounting plate 61. In other embodiments, the sixth power member 65 may also be an electric cylinder, a linear motor, or the like. The sixth power member 65 can drive the second mounting plate 61 to move (i.e. move downwards) in the third direction Z toward the to-be-adsorbed object 1, and the fourth power member 64 drives the moving plate 62 and the suction cup 63 fixedly connected thereto to move (i.e. move upwards) in a direction opposite to the moving direction of the second mounting plate 61.

Preferably, the suction cup 63 is used to suck the second workpiece 102. As shown in fig. 15, a pressing block 68 is further provided at one end of the moving plate 62 near the workpiece 1 for contacting the first workpiece 101. When the suction cup 63 sucks the second workpiece 102, and the sucking assembly 6 brings the to-be-detected part 1 to the upper side of the loading assembly 2, the pressing block 68 can press the first workpiece 101 to the bearing surface of the base 21, so that the first workpiece 101 and the bearing surface are in good contact and can be better attached together, and the first workpiece 101 can be more stably fixed on the bearing surface.

As shown in fig. 4, the adsorption component 6 is slidably connected to the guide rail 7 along the first direction X, so that after the to-be-detected piece 1 is adsorbed, the adsorption component 6 can slide to the upper side of the loading component 2 along the first direction X, and the to-be-detected piece 1 is conveyed to the loading component 2. The overturning assembly 3 and the detecting assembly 4 are respectively positioned on two sides of the loading assembly 2 along the second direction Y. After the loading assembly 2 fixes the first workpiece 101, the overturning assembly 3 overturns the second workpiece 102, the conveying assembly 5 drives the loading assembly 2 to move, so that the to-be-detected workpiece 1 with the opening angle is conveyed to the detection area of the detection assembly 4, and the detection assembly 4 automatically detects the opening angle.
