TECHNICAL FIELD
[0001] The utility model relates to robot design technical field, in particular to a kind of turnover suction label mechanism. BACKGROUND
[0002] In the process of product packaging, the outer package is often required to be labeled. Generally, in the labeling process, the label is first taken, and then attached to the surface of the outer package (such as a color box or a carton). To achieve the above labeling process, a multi-axis robot is usually used to drive a suction label clamp. This design has the advantages of high flexibility, but the multi-axis robot requires precise positioning and program control, which is complex and costly. SUMMARY
[0003] Therefore, the utility model provides a turnover suction label mechanism, which can drive the suction label clamp to complete the combined action of oblique displacement and rotation with one driver, with low control difficulty and low equipment cost.
[0004] A turnover suction label mechanism includes:
[0005] A base is provided with a guide sliding groove;
[0006] A transmission assembly is installed on the base. The transmission assembly includes a first swing arm hingedly connected to one end of the base, a transmission shaft pivotally connected to the other end of the first swing arm, a carrier plate connected to the transmission shaft, a second swing arm connected to one end of the transmission shaft, and a rolling element pivotally connected to the other end of the second swing arm. The transmission shaft, carrier plate, and second swing arm rotate synchronously. The rolling element is slidingly connected to the guide sliding groove.
[0007] A first driver is connected between the base and the transmission assembly. The first driver is provided with a piston rod that performs linear extension and retraction. The tail of the first driver is hingedly connected to the base, and the piston rod is hingedly connected to the first swing arm. The first driver drives the first swing arm to swing through the linear extension and retraction of the piston rod.
[0008] A suction label clamp is connected to the transmission assembly. The suction label clamp is installed on the carrier plate.
[0009] The above-mentioned turnover label suction mechanism, when working, the piston rod of the first driver extends and retracts, and further drives the first swing arm to swing. At the same time when the first swing arm swings, the drive transmission shaft is displaced obliquely, so as to force the carrier plate and the second swing arm to move with the first swing arm. At this time, since one end of the second swing arm is pivotally connected to the rolling element, and the carrier plate and the second swing arm are synchronously rotated, and the rolling element is limited by the guide sliding groove, and further forces the second swing arm to swing, so that the carrier plate also swings in the process of following the first swing arm. Therefore, under the driving of the first driver, the carrier plate can be driven to be obliquely displaced while rotating, so that the label suction clamp completes the displacement while realizing the turnover. Through the above design, one driver can drive the label suction clamp to complete the combined action of oblique displacement and rotation, which has low control difficulty and low equipment cost.
[0010] In one of the embodiments, the transmission assembly further comprises: an elastic element connected to the first swing arm; the elastic element is used to provide an auxiliary force required for resetting the first swing arm. When it is needed to drive the first swing arm to reset, the auxiliary force can be provided by means of the elastic element, so as to reduce the load of the first driver.
[0011] In one of the embodiments, the label suction clamp comprises: a second driver mounted on the carrier plate and a vacuum suction head connected to the second driver; the second driver is used to drive the vacuum suction head to extend and retract.
[0012] In one of the embodiments, the label suction clamp further comprises: a third driver located between the second driver and the vacuum suction head; the third driver is used to drive the vacuum suction head to rotate. The third driver is used to drive the vacuum suction head to rotate to adjust the orientation of the label.
[0013] In one of the embodiments, the turnover label suction mechanism further comprises: a position detection assembly connected to the base; the position detection assembly comprises: an arc-shaped plate mounted on the base, a first position sensor located at one end of the arc-shaped plate, and a second position sensor located at the other end of the arc-shaped plate; the shape of the arc-shaped plate is the same as the swing track of the first swing arm; the first position sensor and the second position sensor are both used to detect whether the first swing arm swings to the end of the arc-shaped plate. Through the electrical signals fed back by the first position sensor and the first position sensor, it can be judged whether the first swing arm has moved to the preset position.
[0014] In one of the embodiments, the turnover label suction mechanism further comprises: a sliding rail slidably connected to the base and a fourth driver connected to the base; the fourth driver is used to drive the base to move laterally along the sliding rail. Under the driving of the fourth driver, the lateral movement of the label suction clamp can be realized.
[0015] In one of the embodiments, the turnover label suction mechanism further comprises a third position sensor on one side of the base; the third position sensor is used to detect whether the base is moved to a preset position laterally. The electrical signal fed back by the third position sensor can be used to determine whether the base has been moved to the preset position. BRIEF DESCRIPTION OF DRAWINGS

[0038] like Figures 1 to 6 As shown, it is a flip-label suction mechanism 100 of this utility model.
[0039] like Figure 1 As shown, the label-flipping mechanism 100 includes: a base 10, a transmission assembly 20 mounted on the base 10, a first driver 30 connected between the base 10 and the transmission assembly 20, and a label-flipping clamp 40 connected to the transmission assembly 20. The base 10 supports the transmission assembly 20 and the first driver 30, and works with the transmission assembly 20 to control the movement trajectory of the label-flipping clamp 40. The first driver 30 transmits power to the label-flipping clamp 40 via the transmission assembly 20, causing the label-flipping clamp 40 to move and flip along a preset trajectory. The label-flipping clamp 40 is used to pick up labels and attach them to target objects (e.g., product packaging).
[0040] like Figure 1 As shown, the base 10 is provided with a guide groove 11. In this embodiment, the guide groove 11 is a horizontally arranged groove.
[0041] like Figure 2 As shown, the transmission assembly 20 includes: a first swing arm 21 hinged at one end to the base 10, a transmission shaft 22 pivotally connected to the other end of the first swing arm 21, a carrier plate 23 connected to the transmission shaft 22, a second swing arm 24 connected at one end to the transmission shaft 22, and a rolling element 25 pivotally connected to the other end of the second swing arm 24. The transmission shaft 22, the carrier plate 23, and the second swing arm 24 rotate synchronously. The rolling element 25 is slidably connected to the guide groove 11. In this embodiment, the rolling element 25 is a roller.
[0042] As shown in Figure 1 , the first driver 30 is provided with a piston rod 31 which can perform linear extension and retraction. The tail of the first driver 30 is hinged on the base 10, and the piston rod 31 is hinged on the first swing arm 21. The first driver 30 drives the first swing arm 21 to swing through the linear extension and retraction of the piston rod 31. In the embodiment, the first driver 30 is a linear extension and retraction cylinder.
[0043] In order to reduce the working load of the first driver 30, as shown in Figure 4 , in the embodiment, the transmission assembly 20 can further include an elastic member 26 connected to the first swing arm 21. The elastic member 26 is used to provide an auxiliary force required for the reset of the first swing arm 21. When the first swing arm 21 needs to be reset, the auxiliary force can be provided by means of the elastic member 26, thereby reducing the load of the first driver 30. In the embodiment, the elastic member 26 is a coil spring.
[0044] As shown in Figure 1 and 2 , the label clamp 40 is installed on the carrier plate 23. As shown in Figure 2 , in the embodiment, the label clamp 40 includes a second driver 41 installed on the carrier plate 23 and a vacuum suction head 42 connected to the second driver 41. The second driver 41 is used to drive the vacuum suction head 42 to perform extension and retraction. In the embodiment, the second driver 41 is a linear extension and retraction cylinder.
[0045] Further, as shown in Figure 2 , the label clamp 40 can further include a third driver 43 located between the second driver 41 and the vacuum suction head 42. The third driver 43 is used to drive the vacuum suction head 42 to perform rotary motion. The third driver 43 is used to drive the vacuum suction head 42 to rotate to adjust the orientation of the label. In the embodiment, the third driver 43 is a rotary cylinder.
[0046] Working principle:
[0047] As shown in Figure 5 , in operation, the piston rod 31 of the first driver 30 performs extension and retraction, thereby driving the first swing arm 21 to swing. At the same time when the first swing arm 21 swings, the drive transmission shaft 22 is forced to perform oblique displacement, thereby forcing the carrier plate 23 and the second swing arm 24 to move with the first swing arm 21. At this time, since one end of the second swing arm 24 is hinged on the rolling member 25, and the carrier plate 23 and the second swing arm 24 are synchronously rotated, and the rolling member 25 is limited by the guide sliding groove 11, thereby forcing the second swing arm 24 to swing, so in the process of the carrier plate 23 following the first swing arm 21, the carrier plate 23 will also swing. Therefore, as shown in Figure 6As shown, under the drive of the first driver 30, the carrier plate 23 can be moved obliquely and rotated at the same time, so that the label suction clamp 40 can be rotated at the same time as it is moved.
[0048] by Figure 5 For example, assuming the label-absorbing fixture 40 is located at the label-picking station, after the label-absorbing fixture 40 absorbs the label, the piston rod 31 of the first driver 30 extends to force the first swing arm 21 to swing counterclockwise. During the counterclockwise swing of the first swing arm 21, the transmission shaft 22 is displaced to the upper left, which in turn drags the second swing arm 24 to the upper left as well. Since the second swing arm 24 is restricted by the rolling element 25 and the guide groove 11, when the first swing arm 21 swings counterclockwise, the second swing arm 24 will also swing clockwise around the pivot point with the rolling element 25. At the same time, the rolling element 25 adapts its posture by sliding to the left, ultimately causing the carrier plate 23 to move to the upper left while swinging clockwise, thereby achieving... Figure 6 The state shown indicates that the label suction clamp 40 has reached the labeling station.
[0049] Combination Figure 3 and Figure 4 As shown, the flipping label-absorbing mechanism 100 may further include a position detection component 50 connected to the base 10. The position detection component 50 includes an arc-shaped plate 51 mounted on the base 10, a first position sensor 52 located at one end of the arc-shaped plate 51, and a second position sensor 53 located at the other end of the arc-shaped plate 51. The shape of the arc-shaped plate 51 is the same as the swing trajectory of the first swing arm 21. Both the first position sensor 52 and the second position sensor 53 are used to detect whether the first swing arm 21 has swung to the end of the arc-shaped plate 51. The electrical signals fed back by the first position sensor 52 and the second position sensor 53 can be used to determine whether the first swing arm has moved to a preset position.
[0050] To facilitate other processes in product manufacturing and to allow for the space needed for those processes, lateral clearance can be implemented when the product is not being labeled. For example, ... Figure 2 and Figure 3 As shown, in this embodiment, the flipping label-absorbing mechanism 100 further includes: a slide rail 60 slidably connected to the base 10 and a fourth driver 70 connected to the base 10. The fourth driver 70 is used to drive the base 10 to move laterally along the slide rail 60. Under the drive of the fourth driver 70, the label-absorbing clamp 40 can move laterally. In this embodiment, the fourth driver 70 is a linear telescopic cylinder.
[0051] Furthermore, such as Figure 2 and Figure 3As shown, the turnover label suction mechanism 100 can further include a third position sensor 80 located on one side of the base 10. The third position sensor 80 is used to detect whether the base 10 is moved laterally to a preset position. The electrical signal fed back by the third position sensor 80 can be used to determine whether the base 10 has been moved to the preset position.
[0052] The turnover label suction mechanism 100 described above can drive the label suction clamp 40 to complete the composite action of oblique displacement and rotation by using one driver, and has low control difficulty and low equipment cost.
[0053] The technical features of the above embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as the scope of the description.
[0054] The above embodiments only express the preferred implementation manners of the utility model, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
