Referring to fig. 4 and 5, fig. 4 and 5 are a front view and a top view of an embodiment of the glue tearing device of the present application, respectively.

A tearing device for removing a flexible member (1) partially adhered to an object (2) comprises a first driving member (10), a grabbing component (20) and a first airflow generator (30) (figure 7).

The first air flow generator 30 is used to generate an air flow to blow the non-bonded portion 102 of the flexible member 1. The non-adhesive portion 102 may be partially folded or entirely folded.

The grabbing component 20 is disposed at the driving end of the first driving component 10, and is driven by the first driving component 10 to move. In one embodiment, the driving end of the first driver 10 is capable of moving in three dimensions with X, Y and Z degrees of freedom. The first driver 10 may include a first sub-driver 11, a second sub-driver 12, and a third sub-driver 13. The second sub-driving member 12 is disposed at the driving end of the first sub-driving member 11, and can reciprocate along the X-axis under the driving of the first sub-driving member 11. The third sub-driving member 13 is disposed at the driving end of the second sub-driving member 12, and can reciprocate along the Y-axis under the driving of the second sub-driving member 12. The grabbing component 20 is arranged at the driving end of the third sub-driving piece 13 and can reciprocate along the Z-axis under the driving of the third sub-driving piece 13. The first sub-driving member 11, the second sub-driving member 12 and the third sub-driving member 13 may be linear motors. The number of the grasping assemblies 20 may be provided in plural (four in the drawing) to improve the working efficiency.

The grabbing assembly 20 is used for grabbing the turned-over part of the flexible piece 1 and removing the flexible piece 1 from the object 2 under the driving of the first driving piece 10.

Fig. 6 is a schematic diagram of a process for removing the flexible member 1 from the object 2 in an embodiment of the present invention. The operation of the glue tearing device will be described with reference to fig. 6.

Section 6a of fig. 6 is detailed below.

The portion 6b in fig. 6 shows the state after the flexible member 1 is folded.

The first air flow generator 30 blows an air flow which causes the non-bonded portion 102 of the flexible element 1 to fold over. After the non-bonded part 102 is folded, a part of the flexible member 1 is tilted, that is, a part of the flexible member 1 is not attached to the object 2. Specifically, the flexible member 1 is blown by the air flow, and the non-bonded portion 102 is turned over as a whole, that is, the non-bonded portion 102 is turned counterclockwise around the upper edge of the bonded portion 101.

The portion 6c in fig. 6 shows a state where the grasping assembly 20 grasps the flexible member 1. The grasping assembly 20 grasps the folded part of the flexible member 1 after the flexible member 1 is folded.

Fig. 6 shows a state where a part of the flexible member 1 is removed from the article 2 in a portion 6d, and a state where the flexible member 1 is completely removed from the article 2 in a portion 6 e.

The first driving member 10 drives the flexible member 1 to move, so as to remove the flexible member 1 from the object 2. In the illustrated embodiment, the first driving member 10 drives the grabbing assembly 20 to move along the negative direction of the X-axis and the negative direction of the Z-axis simultaneously to remove the flexible member 1 from the object 2, but in other embodiments, the first driving member 10 may drive the grabbing assembly 20 to move along the negative direction of the Z-axis first and then along the negative direction of the X-axis to remove the flexible member 1 from the object 2.

In the glue tearing device, the non-bonding part 102 of the flexible part 1 is blown by air flow to be turned over, so that the grabbing component 20 can grab the turned-over part of the flexible part 1, the flexible part 1 can be automatically torn off from the object 2, and the efficiency is improved.

In some application scenarios, the adhesion between the flexible element 1 and the object 2 is small, and the air flow may blow the flexible element 1 away from the object 2 directly. In this case, although the object of removing the flexible member 1 is achieved directly by the air flow, the position of the flexible member 1 is not controllable, and the flexible member 1 cannot be placed at a specified place. To this end, in some embodiments, the grasping assembly 20 is configured to partially press the flexible member 1 against the object 2 under the driving of the first driving member 10 before generating the air flow, and to release the pressing when removing the flexible member 1. It is thereby ensured that the flexible member 1 is not blown off the object 2 before gripping the flexible member 1.

The portion 6a in fig. 6 shows a state where the grasping assembly 20 is pressed against the flexible member 1.

The first driving member 10 drives the grabbing assembly 20 to move along the X-axis, so that the grabbing assembly 20 presses the flexible member 1 against the object 2. The grasping assembly 20 can be pressed against any position of the flexible member 1, so that the flexible member 1 cannot be directly separated from the object 2 under the blowing of the air flow generated by the first air flow generator 30. Illustratively, the upper edge of the abutting surface of the grasping assembly 20 and the flexible member 1 is aligned with the upper edge of the bonded portion 101 in the flexible member 1.

After the air flow blows the flexible part 1 to be turned over, the grabbing component 20 grabs the turned-over part of the flexible part 1 and uncovers the flexible part 1. In this embodiment, the grasping assembly 20 is away from the object 2 and no longer presses against the flexible member 1 during the process of removing the flexible member 1.

In order to make the grasping assembly 20 firmly grasp the flexible member 1 (the tearing process does not break away), in some embodiments, the grasping assembly 20 grasps the folded portion of the flexible member 1 by clamping. Compared with a vacuum adsorption mode, the flexible part 1 can be grabbed more firmly by adopting a clamping mode.

Referring to fig. 7 and 8, fig. 7 and 8 are a front view and a side view of a driving end of the first driving member 10 in an embodiment of the glue tearing device of the present application, respectively.

In some embodiments, the grasping assembly 20 includes a first jaw 21, a second jaw 22, a second driving member 23, a pressing member 24, and an elastic member 25.

To facilitate mounting of the components of the gripping assembly 20, the drive end of the first drive member 10 is provided with a mounting socket 14.

The first jaw 21 and the second jaw 22 can be drawn together to grip the folded portion of the flexible member 1. The second driving member 23 is used for driving the first clamping jaw 21 and the second clamping jaw 22 to close. Illustratively, first jaw 21 is disposed on mount 14, and second jaw 22 is slidably coupled to mount 14 and is movable toward and away from first jaw 21.

The second driver 23 may be a cylinder. Second driving piece 23 is disposed on mounting seat 14, a driving end of second driving piece 23 is connected to second clamping jaw 22, and second driving piece 23 drives second clamping jaw 22 to approach or separate from first clamping jaw 21.

The pressing part 24 is movably connected with the first clamping jaw 21 and can move relatively. In some embodiments, the pressing member 24 is slidably engaged with the first jaw 21 in a predetermined direction.

The elastic member 25 is configured to apply an elastic force to the pressing member 24, so that the pressing member 24 presses the flexible member 1 under the driving of the first driving member 10. In some embodiments, opposite ends of the elastic member 25 in the predetermined direction elastically connect/abut against the pressing member 24 and the first jaw 21, respectively. For example, the elastic member 25 is a spring interposed between the pressing member 24 and the first jaw 21, and the spring has a buffering function when the pressing member 24 presses the flexible member 1.

In this embodiment, the first driving member 10 drives the grasping assembly 20 to move, and the pressing member 24 in the grasping assembly 20 presses against the flexible member 1 at the predetermined position, then the first airflow generator 30 generates airflow, the airflow blows the folded flexible member 1, the folded part of the flexible member 1 enters the area between the first clamping jaw 21 and the second clamping jaw 22, and the second driving member 23 drives the first clamping jaw 21 and the second clamping jaw 22 to clamp the folded part of the flexible member 1.

Through the structural design, the first clamping jaw 21 can be prevented from damaging the flexible part 1 when being pressed against the flexible part 1.

In some embodiments, the first jaw 21 is used to abut against one side of the flexible member 1 after the flexible member 1 is folded, and the second jaw 22 is used to abut against the other side of the flexible member 1 to clamp the folded portion of the flexible member 1. Specifically, under the blowing of the air flow, the turned-over part of the flexible part 1 is attached to the clamping surface 211a of the first clamping jaw 21 (see part 6b in fig. 6), and the position of the turned-over part of the flexible part 1 is stable, so that the clamping success rate of the first clamping jaw 21 and the second clamping jaw 22 can be improved.

Referring to FIG. 6, section 6b, in some embodiments, the direction of the airflow is directed toward the surface of the object 2 and is inclined relative to the surface. Specifically, the direction of the airflow blown out by the first airflow generator 30 is located in the plane of the X-axis and the Z-axis, and extends along the positive direction of the X-axis and the negative direction of the Z-axis. The air flow is turned after blowing to the surface of the object 2 and blows the surface of the flexible piece 1 facing to one side of the object 2, so that the flexible piece 1 is turned over.

In some embodiments, the first airflow generator 30 is disposed at the driving end of the first driver 10 or the grasping element 20. In the illustrated embodiment, the first airflow generator 30 is disposed at the drive end of the first driver 10. When sequentially removing the flexible members 1 at different positions, the first air flow generator 30 can move along with the grasping assembly 20 without separately adjusting the position of the first air flow generator 30. Meanwhile, the flowing direction of the air flow generated by the first air flow generator 30 is always kept unchanged, which is beneficial to keeping the working stability of the glue tearing device. To facilitate adjustment of the angle of the airflow, the mounting position of the first airflow generator 30 may be adjusted. Specifically, a connecting rod is disposed on the upper side of the mounting seat 14, the first airflow generator 30 is fixedly disposed on the connecting rod, a kidney-shaped groove is formed in the surface of the connecting rod, and the position between the connecting rod and the mounting seat 14 is adjusted through the kidney-shaped groove.

The specific configuration of the first airflow generator 30 is not limited in this application. In some embodiments, the first flow generator 30 comprises a housing having a sidewall defining an air outlet 31 communicating with the interior and exterior of the housing, the housing having a cavity for communicating with a source of pressurized air. The high-pressure gas source delivers high-pressure gas into the housing, and the high-pressure gas flows out from the gas outlet 31 to form gas flow. In some embodiments, first airflow generator 30 includes a fan that drives a flow of air to generate an airflow.

In some embodiments, the grasping assembly 20 can also release the grasped flexure 1. After the adhesive tearing device takes off the flexible part 1 from the object 2, the first driving part 10 drives the grabbing component 20 to move to the waste recovery area, the grabbing component 20 releases the grabbed flexible part 1, so that the flexible part 1 falls into the waste recovery area, and the first driving part 10 drives the grabbing component 20 to take off the next flexible part 1. To ensure that the flexible part 1 can be separated from the grabbing assembly 20, the glue tearing device further comprises a second air flow generator 40, wherein the second air flow generator 40 is used for generating air flow to blow the flexible part 1 away from the grabbing assembly 20 after the grabbing assembly 20 releases the grabbed flexible part 1. The specific structure of the second airflow generator 40 may be referred to the first airflow generator 30. In some embodiments, the second airflow generator 40 is disposed at the drive end of the first driver 10 or the grasping element 20.

In some embodiments, the glue-tearing apparatus further comprises a sensor. The sensor may be located at the driving end of the first driver 10 or at the grasping assembly 20. The sensor is used to detect the presence of the flexible member 1 on the gripper assembly 20. The sensor may be used to confirm whether the folded portion of the flexible member 1 is located between the first jaw 21 and the second jaw 22, and further to confirm whether the folded portion of the flexible member 1 abuts against the clamping surface 211a of the first jaw 21, and the sensor may also be used to confirm whether the air flow generated by the second air flow generator 40 blows the flexible member 1 off the gripper assembly 20.

Referring to fig. 9, fig. 9 is a schematic structural diagram of an embodiment of the adhesive tearing device of the present application.

In some embodiments, the glue-tearing apparatus further comprises a flipping assembly 50. The upender assembly 50 comprises a support 51, a mount 52, a quick-fit unit 53 and a third drive 54. The mounting member 52 is rotatably provided to the support 51. The third drive member 54 is used to drive the rotation of the mounting member 52. The third drive member 54 may be a motor. In one application scenario, the third driving member 54 turns the mounting member 52 by 90 °. The quick-mounting unit 53 is provided to the mounting member 52, and is used to fix the object 2 to the mounting member 52. The quick assembly unit 53 may include a rotary compacting cylinder and a clamping block attached to a rotating end of the rotary compacting cylinder. The clamping blocks are spaced from the mounting member 52. The action of the rotary pressing cylinder drives the clamping block to rotate around the reference axis and move along the direction of the reference axis, so that the object 2 is fixed on the mounting piece 52. The reference axis is parallel to the direction in which the clamping block is spaced from the mount 52.
