Description

Technical Field

[0001] The present invention relates to the field of detection devices, and in particular to a pushing mechanism and a detection system. Background Art

[0002] In the detection device, the object can be pushed to the detection position by the push mechanism, and the detection device detects the object to determine whether it is qualified. When the object is transmitted to the front of the push mechanism, the push mechanism can push the object and correct the position of the object to ensure the detection effect. In the prior art, the push mechanism can rotate. When the object is transmitted from the back of the push mechanism to the front and contacts the push mechanism, the push mechanism rotates a certain angle. At this time, the push mechanism can avoid on the transmission path of the object so that the object passes horizontally above the push mechanism. When the object moves to the front of the push mechanism, the push mechanism can rotate back to the initial position under the action of its own gravity. At this time, the push mechanism can move forward to push and correct the position of the object. The object can only move from the back of the push mechanism to the front, and will be blocked when the object moves from the front of the push mechanism to the back. When the object is detected, the object that is successfully detected can continue to move forward, and the object that fails to be detected needs to be returned. At this time, the push mechanism blocks the object and the return operation cannot be completed. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] Reference below Figure 1-Figure 10 A pushing mechanism 100 according to an embodiment of the present invention is described.

[0057] like Figure 1-Figure 3 As shown, the pushing mechanism 100 according to the embodiment of the present invention includes: a displacement device 10 , a driving device 20 and a guiding device 30 .

[0058] The displacement device 10 includes a main board 11 and a pusher 12 movably arranged on the side of the main board 11. The driving device 20 is connected to the main board 11 and is used to drive the displacement device 10 to move. After the guide device 30 contacts the pusher 12, the pusher 12 can be switched between the first state and the second state. The highest point of the pusher 12 in the first state is higher than the highest point in the second state.

[0059] Specifically, the displacement device 10 is connected to the driving device 20 via the main board 11, the pusher 12 on the displacement device 10 can contact with the guide device 30 and guide the pusher 12, and the driving device 20 can drive the displacement device 10 to move, so that the pusher 12 of the displacement device 10 contacts with the guide device 30, and drives the pusher 12 to switch between the first state and the second state. Figure 2 As shown, when the pusher 12 is in the first state, it can push the object in front of it to complete the detection of the object by the detection device. When the detection fails, the object is returned. At this time, the driving device 20 can drive the displacement device 10 to switch the pusher 12 from the first state to the second state under the guidance of the guiding device 30. Figure 3 As shown, the object can be avoided on its moving trajectory.

[0060] Exemplarily, the push mechanism 100 is arranged in the detection system, and the detection system also has a conveying device and a detection device. The conveying device is provided with two guide rails, and the guide rails can transport objects. The push mechanism 100 is arranged in the gap between the two guide rails. The driving device 20 is fixed relative to the conveying device. The driving device 20 drives the push member 12 to switch the state. The highest point of the push member 12 in the first state is higher than the upper surface of the guide rail, and the highest point of the push member 12 in the second state is lower than the upper surface of the guide rail. Therefore, in the first state, the push member 12 can push the object through the part that is higher than the upper surface of the guide rail to transport the object to the detection position. In the second state, since the highest point of the push member 12 is lower than the upper surface of the guide rail, the object's retreat path can be avoided, thereby improving the detection efficiency.

[0061] According to the pushing mechanism 100 of the embodiment of the present invention, when the detection device detects the object, the pushing mechanism 100 can push the object and correct the position. After the detection fails, the pushing member 12 can be switched to the second state under the drive of the driving device 20. At this time, the highest point of the pushing member 12 is lower than the lower surface of the object. The pushing mechanism 100 can avoid on the return path of the object, so that the detection mechanism can complete the object return operation, thereby improving the detection efficiency.

[0062] Optionally, the pushing mechanism 100 is arranged above the detection system, the driving device 20 is arranged higher than the detection system through a door frame, the displacement device 10 is connected to the driving device 20 and extends downward from the driving device 20, the displacement device 10 has a pushing member 12, the lowest point of the pushing member 12 is lower than the top surface of the object in the first state, and the lowest point of the pushing member 12 is higher than the top surface of the object in the second state.

[0063] Specifically, the driving device 20 is fixed by the gantry so that the pushing mechanism 100 is higher than the detection system setting. The displacement device 10 extends downward and can selectively push the object through the pushing member 12. When the pushing member 12 is in the first state, the lowest point of the pushing member 12 is lower than the top surface of the object. At this time, under the drive of the driving device 20, the pushing member can push the object to transport the object to the detection position. When the object detection fails, the pushing member 12 switches to the second state. At this time, the lowest point of the pushing member 12 is higher than the top surface of the object. The driving member 12 can avoid the object on the object's retreat path, thereby improving the detection efficiency.

[0064] like Figure 1 As shown, in some embodiments, the guiding device 30 includes a guiding groove 31 , and a guiding rod 121 is disposed on the pushing member 12 . The guiding rod 121 can drive the pushing member 12 to move under the guidance of the guiding groove 31 .

[0065] Specifically, when the driving device 20 drives the displacement device 10 to switch the state of the pusher 12, the guide rod 121 first contacts the guide groove 31, and then under the guidance of the guide groove 31, the guide rod 121 can move according to the shape of the guide groove 31, and finally the pusher 12 is switched from the first state to the second state or from the second state to the first state. When the pusher 12 switches its state, the guide rod 121 always keeps in contact with the guide groove 31, and the guide groove 31 can constrain the movement trajectory of the guide rod 121.

[0066] Therefore, through the cooperation between the guide rod 121 and the guide groove 31 , the switching of the pushing member 12 between the first state and the second state can be made more stable, thereby improving the reliability of the pushing mechanism 100 .

[0067] like Figure 5 As shown, optionally, the pusher 12 further includes a rolling bearing 122, which is sleeved on the outside of the guide rod 121. When the guide rod 121 on the pusher 12 cooperates with the guide groove 31 on the guide device 30, the rolling bearing 122 sleeved on the outside of the guide rod 121 can contact the guide groove 31, and when the pusher 12 switches between the first state and the second state, the rolling bearing 122 can roll in the guide groove 31, thereby reducing the friction resistance between the pusher 12 and the guide device 30, making the movement of the pusher 12 smoother, thereby improving the reliability of the pushing mechanism 100.

[0068] It should be noted that a roller may be sleeved on the outside of the guide rod 121 or grease may be applied between the guide rod 121 and the guide groove 31 . There is no specific limitation here and the selection may be made according to actual needs.

[0069] like Figure 4-Figure 5As shown, further, the pusher 12 is rotatably connected to the mainboard 11 via a rotating shaft 123 , and the pusher 12 includes an adjacent first edge 124 and a first corner 125 , and the distance between the first corner 125 and the rotating shaft 123 is greater than the vertical distance between the first edge 124 and the rotating shaft 123 .

[0070] Specifically, the pusher 12 is fixed to the main board 11 via the rotating shaft 123, and the pusher 12 can rotate relative to the main board 11. When the pusher 12 is in the first state, the highest point of the pusher 12 is located at the first corner 125, and when the pusher 12 is in the second state, the highest point of the pusher 12 is located on the first side 124. Figure 5 As shown, the difference H between the highest point of the pushing member 12 in the first state and the highest point in the second state is.

[0071] That is to say, when the pushing member 12 moves from the first state to the second state, the driving device 20 first drives the displacement device 10, and the driving device 20 drives the main board 11 to move synchronously. The pushing member 12 rotates relative to the main board 11 under the constraint of the rotating shaft 123. When the pushing member 12 switches from the first state to the second state, the height of the highest point of the pushing member 12 changes in the direction perpendicular to the main board 11, and the distance between the first corner 125 and the rotating shaft 123 is greater than the vertical distance between the first side 124 and the rotating shaft 123.

[0072] Therefore, in the second state, the highest point of the pusher 12 is lower than the highest point in the first state. At this time, the pusher 12 can avoid the object's conveying path to enable the detection device to complete the retraction operation, thereby improving the detection efficiency of the detection device.

[0073] like Figure 6 As shown, optionally, a counterweight block 126 is provided on the pusher 12, and the counterweight block 126 and the first angle 125 are respectively located on both sides of the axis of the rotating shaft 123 in the horizontal direction, so that the pusher 12 has a tendency to remain in the first state. The counterweight block 126 can be an integral structure with the pusher 12 or the counterweight block 126 can be fixed to the pusher 12 through a connecting device.

[0074] Specifically, in the horizontal direction, the first angle 125 and the counterweight 126 are respectively located on both sides of the axis of the rotating shaft 123. When the pusher 12 is connected to the main board 11 through the rotating shaft 123, the center of gravity of the pusher 12 is located on the side of the axis of the rotating shaft 123 that is biased toward the counterweight 126, that is, when there is no external force interference, the pusher 12 will rotate toward the side of the counterweight 126, so that the pusher 12 remains in the first state, and the first angle 125 at this time is the highest point of the pusher 12 in the first state.

[0075] As title 2, Figure 4As shown, illustratively, the pusher 12 can be formed as a triangular block, the rotation axis 123 is arranged at one corner of the triangular block, the first corner 125 and the counterweight block 126 are respectively arranged at the other two corners of the triangular block, and the side connecting the first corner 125 and the corner where the counterweight block 126 is located is the first side 124. The pusher 12 can rotate freely along the rotation axis 123, and the counterweight block 126 can make the pusher 12 have a tendency to rotate clockwise under the action of gravity, and the highest point of the pusher 12 is located at the first corner 125, and the pusher 12 is in the first state.

[0076] When the object is pushed by the pushing mechanism 100, the object is located in front of the pushing mechanism 100, the pushing member 12 is in the first state, the driving device 20 drives the displacement device 10 to move forward, and the pushing member 12 can push the object forward for detection. The pushing member 12 and the object stop, so that the pushing member 12 is always in the first state. When the object detection fails, the object needs to be returned. At this time, the driving device 20 drives the displacement device 10 to move backward. Under the guidance of the guiding device 30, the pushing member 12 can switch from the first state to the second state. The highest point of the pushing member 12 is lower than the lowest point of the object, and it can avoid it on the return path of the object.

[0077] When the object completes the retraction operation and needs to be pushed by the pushing mechanism 100, the driving device 20 drives the displacement device 10 to move forward, and the pushing member 12 rotates toward the side of the counterweight block 126 under the action of its own gravity to switch from the second state to the first state and continue to push the object.

[0078] Therefore, by setting the counterweight block 126, the pushing member 12 can have a tendency to remain in the first state. After providing avoidance for the object to retreat, it can automatically switch back to the first state to push the next object, which can improve the pushing efficiency of the pushing mechanism 100 and further improve the detection efficiency of the detection device.

[0079] It should be noted that the counterweight 126 can be an integral structure with the pusher 12, or can be fixedly connected to the pusher 12 through a connecting device. When the counterweight 126 is an integral structure with the pusher 12, the counterweight 126 can be integrally formed with the pusher 12 by casting or forging to reduce the assembly process. When the counterweight 126 is connected to the pusher 12 through a connecting device, the connecting device can be a bolt, a rivet or a pin. During assembly, the counterweight 126 is connected to the pusher 12 through the connecting device. The weight of the counterweight 126 can be adjusted according to demand so that the pusher 12 has a tendency to remain in the first state when not subject to external force.

[0080] like Figure 6As shown, optionally, a positioning block 112 is provided on the main board 11 , and a positioning portion 120 is further provided on the side of the pusher 12 opposite to the counterweight block 126 . When the pusher 12 is in the first state, the positioning portion 120 can abut against the positioning block 112 .

[0081] Specifically, the positioning portion 120 is located on the side of the pusher 12 and is arranged opposite to the counterweight block 126. The positioning portion 120 is formed as an inwardly concave avoidance groove on the side of the pusher 12, and a positioning surface is provided in the avoidance groove, and the positioning surface can abut against the positioning block 112. When the pusher 12 is in the first state, under the gravity of the counterweight block 126, the pusher 12 has a tendency to remain in the first state, that is, the pusher 12 has a tendency to rotate toward the side of the counterweight block 126. When the positioning portion 120 abuts against the positioning block 112, the rotation of the pusher 12 can be limited, so that the pusher 12 remains stable in the first state, thereby improving the pushing effect of the pusher 12 on the object.

[0082] like Figure 7 As shown, in some embodiments, the surface of the guide groove 31 is a curved surface, which includes a lower section 311, a middle section 312 and an upper section 313 connected in sequence, wherein the slope of the middle section 312 is greater than that of the lower section 311, and the angle between the upper section 313 and the middle section 312 is less than or equal to 90 degrees. The slope of the lower section 311 gradually increases from bottom to top.

[0083] Specifically, when the guide rod 121 on the pushing member 12 cooperates with the guide groove 31, the guide groove 31 can guide the movement of the guide rod 121. When the driving device 20 drives the displacement device 10 to switch from the first state to the second state, the guide rod 121 first contacts the lower section 311 of the guide groove 31. The slope of the lower section 31 is small, which can provide a buffer for the guide rod 121 when the guide rod 121 contacts the surface of the guide groove 31, thereby preventing the guide rod 121 from colliding with the guide groove 31 when contacting, causing wear on the surface of the guide groove 31.

[0084] Then, the guide rod 121 gradually moves from the lower section 311 to the middle section 312 under the guidance of the guide groove 31. During the movement, the slope of the guide groove 31 increases continuously, so that the push member 12 can switch from the first state to the second state more quickly in a shorter stroke, thereby improving the switching efficiency of the push member 12.

[0085] Finally, when the guide rod 121 moves to the junction of the upper section 313 and the middle section 312 of the guide groove 31, the pusher 12 is in the second state, and the angle between the upper section 313 and the middle section 312 can limit the guide rod 121 so that the pusher 12 remains stable in the second state. The angle between the upper section 313 and the middle section 312 is less than or equal to 90 degrees, which can prevent the guide rod 121 from continuing to move along the guide groove 31 after the pusher 12 switches to the second state.

[0086] Therefore, the switching efficiency of the pusher 12 from the first state to the second state can be higher, and the pusher 12 can be kept stable in the second state.

[0087] like Figure 8 As shown, optionally, a ball joint is used between the driving device 20 and the main board 11.

[0088] Specifically, when the driving device 20 is connected to the main board 11 through the ball joint, a sphere is provided on one of the driving device 20 and the main board 11, and a spherical shell is provided on the other of the driving device 20 and the main board 11. The sphere is sealed and connected to the spherical shell, and lubricating oil is contained in the spherical shell. When the driving device 20 drives the displacement device 10 to move, the sphere can rotate within a certain range in the spherical shell. Since the pushing member 12 is arranged on the side of the main board 11, the pushing member 12 can rotate within a certain range. Before the object is detected by the detection device, the object may be in a tilted state. At this time, the detection of the object will produce a large error and cannot meet the detection requirements. The object is pushed by the pushing member 12, and since the pushing member 12 can rotate within a certain range, the posture of the object can be slightly corrected to straighten the object, thereby meeting the detection requirements.

[0089] Thereby, the detection efficiency of the detection device can be improved.

[0090] like Figure 3 , Figure 8 As shown, in some embodiments, the driving device 20 and the main board 11 are connected in an articulated manner. A groove 21 is provided on one of the driving device 20 and the main board 11, and a plate-like portion 111 that can be horizontally inserted into the groove 21 is provided on the other. A pin 22 is vertically passed through the groove 21 and the plate-like portion 111, wherein there is a gap between the front edge of the plate-like portion 111 and the bottom of the groove 21. By inserting the pin 22 into the groove 21 and the plate-like portion 111, the driving device 20 can be connected to the main board 11, and because there is a gap between the front edge of the plate-like portion 111 and the bottom of the groove 21, the main board 11 can be rotated in the horizontal direction relative to the driving device 20, thereby making a slight correction to the posture of the object.

[0091] Thereby, the detection efficiency of the detection device can be improved.

[0092] It should be noted that the size of the gap between the front edge of the plate-like portion 111 and the bottom of the groove 21 is not specifically limited and can be set according to actual needs.

[0093] Preferably, the gap between the front edge of the plate-like portion 111 and the bottom of the groove 21 is L, L = 1 mm. By setting a gap of 1 mm, the displacement device 10 can rotate 2 degrees on the horizontal plane, and the connection stability between the displacement device 10 and the driving device 20 can be higher while the displacement device 10 corrects the posture of the object.

[0094] In some embodiments, the motion mode of the pusher 12 from the first state to the second state is movement, rotation or a combination thereof. There is no specific limitation on the motion mode of the pusher 12 switching between the first state and the second state. The pusher 12 can switch between the first state and the second state by movement, rotation or a combination thereof. When the pusher 12 uses different motion modes, the guiding means 30 for guiding the pusher 12 also needs to be adjusted accordingly.

[0095] like Fig. 9 , Fig.10 As shown, according to the pushing mechanism of the second embodiment of the present invention, the pushing member 12 is movably connected to the main board 11. The guiding device 30 includes a slide rail 32 with a lifting stroke, and a slider 128 is provided on the pushing member 12 and can slide in the slide rail 32. The slide rail 32 contacts the upper and lower surfaces of the slider 128, and guides the slider 128 to rise and fall as the slide rail 32 moves.

[0096] Specifically, the pusher 12 has a sliding groove 127, and the rotating shaft 123 can slide up and down in the sliding groove 127. The slider 128 on the pusher 12 can move in the slide rail 32 of the guide device 30, and the slide rail 32 can constrain the slider 128 on the upper and lower surfaces. When the driving device 20 drives the displacement device 10 to move, so that the pusher 12 switches from the first state to the second state, the main board 11 moves backward under the drive of the driving device 20, and the slider 128 of the pusher 12 can descend along the slide rail 32 under the constraints of the upper and lower surfaces of the slide rail 32. Through the cooperation of the sliding groove 127 and the rotating shaft 123, the pusher 12 can move downward, so that the height of the highest point of the pusher 12 is continuously reduced. When the pusher 12 is in the second state, the height of the highest point of the pusher 12 is lower than the height of the lowest point of the object, thereby providing avoidance for the object.

[0097] like Fig. 9 , Fig.11 As shown, according to the pushing mechanism of the third embodiment of the present invention, the pushing member 12 is movably connected to the main board 11. The guiding device 30 includes a slide rail 32 with a lifting stroke, and a slider 128 is provided on the pushing member 12, which can slide in the slide rail 32. The slide rail 32 is in contact with the upper surface of the slider 128, and the displacement device 10 includes a reset member 129, which is used to apply an upward force to the pushing member 12, and the slider 128 is lifted and lowered during the movement of the slide rail 32 through the combined force of the slide rail 32 and the reset member 129.

[0098] Specifically, the pusher 12 has a sliding groove 127, and the rotating shaft 123 can slide up and down in the sliding groove 127. The slider 128 on the pusher 12 can move in the slide rail 32 of the guide device 30. The slider 128 of the pusher 12 can always contact the upper surface of the slide rail 32 through the force of the reset member 129 on the pusher 12. When the driving device 20 drives the displacement device 10 to move, so that the pusher 12 switches from the first state to the second state, the main board 11 moves backward under the drive of the driving device 20, and the slider 128 of the pusher 12 can be close to the upper surface of the slide rail 32 and descend. Through the cooperation of the sliding groove 127 and the rotating shaft 123, the pusher 12 can move downward, so that the height of the highest point of the pusher 12 is continuously reduced. When the pusher 12 is in the second state, the height of the highest point of the pusher 12 is lower than the height of the lowest point of the object, thereby providing avoidance for the object.

[0099] According to the detection system of the second embodiment of the present invention, the detection system comprises: the pushing mechanism 100, the conveying mechanism and the detecting mechanism described in any one of the above embodiments. The pushing mechanism 100 can push the object on the conveying mechanism to move to the detection position, and the detecting mechanism is used to detect the object at the detection position.

[0100] According to the detection system implemented in the second embodiment of the present invention, by setting the above-mentioned pushing mechanism 100 in the detection system, the object can be returned by the conveying mechanism after the object detection fails, and the pushing mechanism 100 can avoid on the return path of the object, thereby improving the detection efficiency of the detection system.
