Therefore, the jig plate 11 is connected with the rotation output end of the second rotation module 32, the supporting plate 12 is used for bearing the to-be-detected piece 200, and the supporting plate 12 is detachably connected with the jig plate 11, so that one surface of the supporting plate 12 for bearing the to-be-detected piece 200 can be processed more precisely, for example, one surface of the supporting plate 12 for bearing the to-be-detected piece 200 can be processed into a smooth surface, and damage to the to-be-detected piece 200 caused by burrs, bulges and the like on the supporting plate 12 can be prevented; meanwhile, damage to the pallet 12 for carrying the workpiece 200 to be inspected due to connection of the jig plate 11 and the rotation output end of the second rotation module 32 can be prevented.

And, the supporting plate 12 is detachably connected with the jig plate 11, so that the supporting plate 12 with different thickness can be used for carrying when detecting the to-be-detected pieces 200 with different thickness, so that the to-be-detected pieces 200 carried on the supporting plate 12 can be pressed by the pressing piece 21. For example, when the thickness of the member to be detected 200 is smaller, the supporting plate 12 with a larger thickness may be used, so that the distance between the pressing member 21 and the member to be detected 200 is within the pressing range of the pressing member 21, and thus the member to be detected 200 with a smaller thickness can be pressed on the supporting plate 12 by the pressing member 21; when the thickness of the member to be inspected 200 is thicker, the pallet 12 having a thinner thickness may be used so that the member to be inspected 200 can be placed between the pressing member 21 and the pallet 12 and can be pressed against the pallet 12.

In addition, when the geometric center of the supporting plate 12 coincides with the geometric center of the jig plate 11, and the orthographic projection of the supporting plate 12 on the jig plate 11 is located in the plate surface of the jig plate 11, at this time, the space where the supporting plate 12 is located is set to be a region capable of being detected, and the to-be-detected piece 200 is placed in the plate surface of the supporting plate 12, that is, the to-be-detected piece 200 can be located in the region capable of being detected, that is, the supporting plate 12 can play a certain role in positioning the to-be-detected piece 200. Moreover, when the detection platform 110 includes the first horizontal movement module 41 and the second horizontal movement module 42, the to-be-detected piece 200 moves from one position (for example, the to-be-detected piece 200 is placed on the jig 1 from the feeding area) to a position area that can be detected, only the moving distance of the jig 1 needs to be considered, and the generated position error of each time of placing the to-be-detected piece 200 does not need to be considered additionally, so that the control procedures of the first horizontal movement module 41 and the second horizontal movement module 42 are simplified.

The pressing member 21 may have various implementations, for example, the pressing member 21 may be a pressing block, or the pressing member 21 may be a pressing roller, or the pressing member 21 may be a pressing plate, which is not limited herein.

In addition, the outer surface of the pressing member 21 is coated with an elastic layer, so that when the pressing member 21 presses the member 200 to be detected, soft contact is formed between the pressing member 21 and the member 200 to be detected, and damage to the member 200 to be detected caused by the pressing member 21 is prevented.

The elastic layer may be any of a rubber layer, a sponge layer, a foam layer, and the like, and is not limited thereto.

The compressing element 21 is movably arranged on the jig 1 along the direction approaching or departing from the jig 1, and in one possible implementation manner, the compressing assembly 2 can further comprise an air cylinder, a piston rod of the air cylinder can extend or retract along the direction approaching or departing from the jig 1, the piston rod is connected with the compressing element 21, and the extending or retracting of the piston rod can drive the compressing element 21 to move along the direction approaching or departing from the jig 1.

In another possible implementation, as shown in fig. 3-5, the compressing element 21 is rotatably connected with the fixture 1, the compressing assembly 2 further includes a restoring element 22, one end of the restoring element 22 is connected with the compressing element 21, the other end of the restoring element 22 is connected with the fixture 1, and the restoring element 22 is used for providing a force for the compressing element 21 to rotate towards the fixture 1.

From this, compress tightly piece 21 and tool 1 rotate to be connected, can make compress tightly piece 21 towards the direction that is close to tool 1 to compress tightly the piece 200 that waits to detect that bears on tool 1, perhaps rotate towards the direction that keeps away from tool 1, in order to release the piece 200 that waits to detect that bears on tool 1 and compress tightly. Moreover, the reset piece 22 provides a force for the pressing piece 21 to rotate towards the direction close to the jig 1, so that the pressing piece 21 can automatically press the piece 200 to be detected on the jig 1, and the piece 200 to be detected borne on the jig 1 can be always in a pressed state.

The pressing member 21 is rotatably connected with the jig 1, or the pressing member 21 is rotatably connected with the jig 1 through a rotating shaft, or the pressing member 21 is rotatably connected with the jig 1 through a hinge, which is not limited.

The return member 22 may be any of a spring, a leaf spring, etc., and is not limited thereto.

For example, when the compressing member 21 is connected to the jig 1 through the rotating shaft, the restoring member 22 is a spring, and the spring may be sleeved on the rotating shaft, one end of the spring is connected to the jig 1, and the other end of the spring is connected to the compressing member 21, so that the compressing member 21 has a tendency to rotate toward the direction approaching to the jig 1 under the action of the elastic force of the spring.

In addition, when the pressing member 21 moves away from the jig 1, the force provided by the reset member 22 can be manually overcome to move the pressing member 21 away from the jig 1.

Alternatively, as shown in fig. 1 and 2, the detection platform 110 may further include an opening and clamping assembly 5, where the opening and clamping assembly 5 includes an opening and clamping driving mechanism 51 and a pressing block 52, the driving end of the opening and clamping driving mechanism 51 is connected to the pressing block 52, the opening and clamping driving mechanism 51 is used to drive the pressing block 52 to move toward a direction close to or away from the pressing assembly 2, and when the pressing block 52 presses the pressing piece 21 along a direction close to the pressing assembly 2, the pressing piece 21 can move toward a direction away from the jig 1, so as to release the piece 200 to be detected between the pressing piece 21 and the jig 1.

From this, when pressing from both sides actuating mechanism 51 drive briquetting 52 towards being close to the direction extrusion of compressing tightly subassembly 2 and compressing tightly piece 21, compressing tightly piece 21 removes towards the direction of keeping away from tool 1 for compressing tightly piece 21 can release the compress tightly of treating detecting piece 200, can take off treating detecting piece 200 from tool 1 promptly, easy operation is convenient.

The open-clamp driving mechanism 51 may be a combination of a cylinder, a motor and a screw nut, a combination of a motor and a rack and pinion, or the like, and is not limited thereto.

In addition, when the pressing piece 21 is rotationally connected with the jig 1, one end, far away from the jig 1, of the pressing piece 21 may be provided with a rotating arm, which may extend approximately in a horizontal direction and be rotationally connected with the jig 1 through a rotating shaft, one end, far away from the pressing piece 21, of the rotating arm may be provided with a pressure-bearing piece, which is used for abutting against the pressing piece 52 when the pressing piece 52 approaches the pressing assembly 2, so that when the opening clamp driving mechanism 51 drives the pressing piece 52 to move in a direction approaching the pressing assembly 2, the pressing piece 52 may abut against the pressure-bearing piece, and the pressure-bearing piece is continuously extruded to enable the rotating arm to rotate around the rotating shaft, so that the pressing piece 21 can move in a direction far away from the jig 1.

Optionally, the opening clamp assembly 5 may further include a bracket 53, where the bracket 53 may be disposed on a side of the second rotating module 32 facing away from the first rotating module 31, the opening clamp driving mechanism 51 may be disposed on a top end of the bracket 53, and the opening clamp driving mechanism 51 may drive the pressing block 52 to move up and down along a vertical direction, so that when the pressing piece 21 is required to move in a direction away from the jig 1, the opening clamp driving mechanism 51 may drive the pressing block 52 to move down and press the pressing piece 21 to rotate around the rotating shaft in a direction away from the jig 1, so as to release the pressing of the piece 200 to be detected, or place a new piece 200 to be detected on the jig 1.

The bottom end of the bracket 53 may be connected with a moving mechanism, where the moving mechanism may drive the bracket 53 to move along the first horizontal direction in a direction approaching away from the jig 1, so that when the pressing piece 21 needs to be pressed down, the moving mechanism may drive the bracket 53 to move in a direction approaching to the jig 1 until the pressing block 52 is located above the pressing piece 21; when the pressing member 21 does not need to be pressed down, the moving mechanism can drive the bracket 53 to move away from the jig 1, so that the clamping opening assembly 5 is prevented from interfering with the rotation and detection of the member 200 to be detected.

In addition, when the detection platform 110 includes the first horizontal moving module 41 and the second horizontal moving module 42, the bracket 53 may also be fixedly disposed on the ground, and the jig 1 and the pressing component 2 may move toward a direction approaching or away from the clamping component 5 through the first horizontal moving module 41 and the second horizontal moving module 42, so that when the pressing piece 21 needs to be pressed down, the first horizontal moving module 41 and the second horizontal moving module 42 may drive the rotating component 3 to move toward a direction approaching the clamping component 5, that is, drive the jig 1 and the pressing component 2 to move toward a direction approaching the clamping component 5 until the pressing piece 21 is located below the pressing block 52; when the pressing member 21 does not need to be pressed down, the first horizontal movement module 41 and the second horizontal movement module 42 can drive the rotating assembly 3 to move away from the opening clamp assembly 5, so that the opening clamp assembly 5 is prevented from interfering with the rotation and detection of the member to be detected 200.
