[0001] This utility model belongs to the field of film-tearing technology in 3C product processing, and particularly relates to a quick-release film-tearing gripper structure. Background Technology

[0002] Previous film-tear designs used two flat jaws to directly clamp the film, which resulted in issues such as the film being pulled up during tearing, failing to tear off, or failing to be thrown off, occurring in about 4% of cases. This led to increased production costs and reduced production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems by providing a quick-release film-tearing gripper structure that can solve the above-mentioned technical issues.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This quick-release film-tear gripper structure includes an adapter base, at least one gripper arm on the adapter base, at least one fixed gripper portion at one end of the gripper arm away from the adapter base, and at least one movable gripper portion hinged to the gripper arm to form a gripping space with the fixed gripper portion. The movable gripper portion is connected to a drive assembly, and an air vent for blowing air into the gripping space is provided in the fixed gripper portion.

[0006] In the above-described quick-release film-tear gripper structure, at least a portion of the air vent is perpendicular to the clamping space.

[0007] In the above-mentioned quick-release film-tearing gripper structure, each of the fixed gripper portions is provided with 1-N air vents.

[0008] In the above-mentioned quick-release film-tearing gripper structure, an ion air delivery hole communicating with the air outlet is provided inside the gripper arm.

[0009] In the above-described quick-release film-tear gripper structure, the number of movable gripper portions corresponds one-to-one with the number of fixed gripper portions.

[0010] In the above-described quick-release film-tear gripper structure, a hinge seat is connected to the end of the gripper arm away from the adapter fixing seat via a concave-convex structure, and the movable gripper part is hinged to the hinge seat.

[0011] In the above-mentioned quick-release film-tear gripper structure, the concave-convex structure includes a concave step and a convex protrusion, one of which is provided on the gripper arm and the other is provided on the hinge seat.

[0012] In the above-described quick-release film-tearing gripper structure, the fixed gripper portion is fixed to the fixed block, and the fixed block is fixed to the hinge seat. At least a portion of the hinge seat extends to the side of the fixed gripper portion, and the movable gripper portion is hinged to at least a portion of the hinge seat.

[0013] In the above-mentioned quick-release film-tearing gripper structure, the driving component includes any one of a hydraulic cylinder driving component, a pneumatic cylinder driving component, and a linear motor; a plurality of gripper arms are arranged on the adapter fixing seat, and the plurality of gripper arms are distributed at equal or non-equal intervals.

[0014] In the above-mentioned quick-release film-tear gripper structure, a transfer positioning hole is provided on the adapter fixing seat.

[0015] Compared with existing technologies, the advantages of this application are:

[0016] The improved membrane gripping and the addition of an ion air vent above the grippers for air-assisted material ejection can control the proportion of membrane lifting / unremovable / unremovable material ejection to around 1%, aiming to reduce the cost waste caused by the risk of membrane lifting during the tearing process. The integrated design also reduces debugging time.

Detailed Implementation

[0024] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the utility model. However, the utility model is not limited to these embodiments.

[0025] This embodiment provides a three-axis coordinate system, namely, the XYZ axes, with the X and Y axes perpendicular to each other in a plane perpendicular to the Z axis.

[0026] Example 1

[0027] like Figure 1 and Figure 3 As shown, this quick-release film-tear gripper structure includes an adapter fixing base 1, which is plate-shaped. To facilitate positioning and connection, the adapter fixing base 1 is provided with adapter positioning holes 10. In this embodiment, there are two adapter positioning holes 10 arranged in an array. With this structure, the adapter fixing base 1 is provided with adapter positioning holes 10, and positioning pins are inserted into the adapter positioning holes 10. The positioning pins are matched with the installation terminal position, which can greatly reduce the installation and debugging time and improve the work efficiency.

[0028] At least one gripper arm 2 is provided on the adapter fixing seat 1. For example, several gripper arms 2 are arranged in a row on the adapter fixing seat 1. The several gripper arms 2 are distributed at equal or non-equal intervals.

[0029] The gripper arms 2 are arranged in a row, which can enable multiple production lines to operate simultaneously.

[0030] According to the Z-axis, such as Figure 1 and Figure 5 As shown, the gripper arm 2 includes an upper fixed seat 21 and an extension arm 22 connected to the side of the upper fixed seat 21. The upper fixed seat 21 and the extension arm 22 are connected by multiple sets of bolt pairs. Meanwhile, a positioning notch is provided on the side of the upper fixed seat 21, and a positioning protrusion that is engaged in the positioning notch is provided on the side of the extension arm 22. In this way, the stability of the overall structural strength and the accuracy of the position can be ensured.

[0031] At least one fixed gripper 3 is provided at the end of the gripper arm 2 away from the adapter fixing seat 1. Of course, two fixed gripper parts 3 spaced apart can be provided on one gripper arm 2 at the same time. The corresponding number of fixed gripper parts 3 can be set according to actual requirements to meet the film tearing requirements.

[0032] And at least one movable gripper 4 is hinged to the gripper arm 2 to form a gripping space with the fixed gripper 3. The movable gripper 4 is equivalent to being able to rotate around the hinge center, that is, to alternate between the gripping position and the non-gripping position.

[0033] Secondly, the movable gripper 4 is connected to the drive assembly 5. The drive assembly 5 includes any one of a hydraulic cylinder drive assembly, a pneumatic cylinder drive assembly, and a linear motor. Taking the pneumatic cylinder drive assembly as an example, it can be a pen-shaped cylinder, with one end of the pen-shaped cylinder hinged to the gripper arm 2, and the telescopic rod of the pen-shaped cylinder hinged to the movable gripper 4. When the pen-shaped cylinder performs telescopic movement, the movable gripper 4 can alternately switch between the gripping position and the non-gripping position.

[0034] One end of the pen-shaped cylinder is hinged to a hinged U-shaped seat, which is fixed to the side of the gripper arm 2. The fixing method includes bolts, etc.

[0035] Preferably, the number of movable gripper parts 4 corresponds one-to-one with the number of fixed gripper parts 3 to meet the clamping requirements. Of course, the number of movable gripper parts 4 hinged to the same gripper arm 2 is, for example, 1-2. If the number exceeds 1, the movable gripper parts 4 can be an integral structure or a split structure. The two split movable gripper parts 4 can be driven by one drive component 5 or by two separate drive components 5. The gripper arms 2 are arranged in an array, and the number of movable gripper parts 4 is, for example, 1 or 2.

[0036] Preferably, such as Figure 2 and Figure 4 As shown, an air vent 30 is provided inside the fixed gripper portion 3 to blow air into the clamping space, and at least a portion of the air vent 30 is vertically distributed with respect to the clamping space. The blown air is ionizing air, and an external ionizing air source is connected to the air vent 30 to perform the air supply action.

[0037] Along the Z-axis, the air vent 30 is positioned above the movable gripper 4, providing air-assisted material throwing. This can control the proportion of film being picked up / not torn off / not thrown off to around 1%, reducing cost losses. For example, in mobile phone production, this design aims to reduce the cost waste caused by the risk of film being picked up during the tearing process, through integrated design, and by reducing debugging time.

[0038] In a preferred embodiment, each fixed gripper 3 is provided with 1-N air vents 30. When there is more than one air vent 30, for example, two air vents 30 are arranged at intervals but connected in parallel. The external ion air source can be one air source directly connected to the two air vents 30 to reduce costs.

[0039] Secondly, an ion air delivery hole 20, communicating with the air outlet 30, is provided inside the gripper arm 2. The ion air delivery hole 20 is connected to an external ion air source. The ion air delivery hole 20 is L-shaped to facilitate communication with the external ion air source. At the same time, the diameter of the ion air delivery hole 20 is larger than the diameter of the air outlet 30, so that the air has a compression and acceleration effect.

[0040] In this embodiment, the film can be clamped by the fixed gripper 3 and the movable gripper 4, and the designed air vent 30 can control the proportion of film being pulled up / not being torn off / not being thrown off to about 1%, thereby reducing cost losses.

[0041] The shape of the air vent 30 can be any one of a circle, an ellipse, or a rectangle.

[0042] Example 2

[0043] Based on Embodiment 1, this embodiment further discloses the following: Figure 4 As shown, a hinge seat 6 is connected to the end of the gripper arm 2 away from the adapter fixing seat 1 via a concave-convex structure. For example, the concave-convex structure includes a concave step 60 and a convex protrusion 61. Either the concave step 60 or the convex protrusion 61 is provided on the gripper arm 2, and the other is provided on the hinge seat 6. The concave step 60 and the convex protrusion 61 are connected by several fasteners.

[0044] Secondly, the movable gripper part 4 is hinged to the hinge seat 6.

[0045] In addition, such as Figure 2 and Figure 4 As shown, the fixed gripper 3 is fixed to the fixed block 3a, and the fixed block 3a is fixed to the hinge seat 6. At least a portion of the hinge seat 6 extends to the side of the fixed gripper 3, and the movable gripper 4 is hinged to at least a portion of the hinge seat 6. The hinge includes a hinge hole and a hinge shaft, either of which is located in the movable gripper 4, and the other is located in at least a portion of the hinge seat 6.
