Description

Technical Field

[0001] This invention relates to flexible sheet assembly equipment, and more particularly to a flexible sheet tearing mechanism and flexible sheet assembly equipment. Background Technology

[0002] In the manufacturing of electronic devices, the assembly of multiple parts is usually involved, and these assembly processes are required to be completed automatically by assembly equipment. For some parts, there is a release film on their surface, which needs to be removed before assembly. The release film is removed by a specially configured film-peeling mechanism.

[0003] In related technologies, for typical parts, which possess a certain degree of hardness, the release film on the surface of the part is relatively easy to remove during the film removal process without damaging the part itself. However, for flexible sheet materials, such as thin metal frames, the flexible sheet material tends to curl upwards with the robotic arm during the film removal process, leading to deformation and even rendering the flexible sheet material unusable. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the object of this invention is to provide a flexible sheet film tearing mechanism and a flexible sheet assembly device.

[0005] To achieve the above objectives, on one hand, a flexible sheet film removal mechanism according to an embodiment of the present invention is used to remove the release film from the surface of the flexible sheet, comprising:

[0006] Multi-axis robotic arm;

[0007] A film-tearing gripper assembly is mounted on the multi-axis robotic arm to grip the handle of the release film and move along the X-axis direction under the drive of the multi-axis robotic arm to remove the release film.

[0008] A film-peeling blade assembly is mounted on the multi-axis robotic arm and arranged side-by-side with the film-peeling gripper assembly in the X-axis direction. The film-peeling blade assembly includes a peeling plate and a lifting drive device. The peeling plate is connected to the lifting drive device so that the peeling plate is driven to descend along the Z-axis direction to approach the release film, and moves synchronously with the film-peeling gripper assembly in the X-axis direction during film peeling.

[0009] In addition, the flexible sheet film tearing mechanism according to the above embodiments of the present invention may also have the following additional technical features:

[0010] According to one embodiment of the present invention, the film-tearing gripper assembly includes:

[0011] First finger pinch;

[0012] The second clamping finger is positioned opposite to the first clamping finger;

[0013] A driver, connected to the first and second gripping fingers, is used to drive the first and second gripping fingers to move relative to each other to perform a clamping or releasing action.

[0014] According to one embodiment of the present invention, the peeling blade is provided with a cut on one side adjacent to the film-tearing gripper assembly, and the projection of the lower ends of the first and second grippers in the Z-axis direction is at least partially located within the cut.

[0015] According to one embodiment of the present invention, an elastic element is provided between the peeling blade and the lifting drive device so that the peeling blade can float elastically.

[0016] According to one embodiment of the present invention, the peeling plate is provided with roller assemblies on both sides in the Y-axis direction. The roller assemblies are pivotable about the axis in the Y-axis direction, and the lowest point of the roller surface is located below the bottom surface of the peeling plate to define the gap between the bottom surface of the peeling plate and the release film.

[0017] According to one embodiment of the present invention, the film-peeling blade assembly further includes:

[0018] A sliding arm, which is connected to the lifting drive device, is driven by the lifting drive device to slide in the Z-axis direction;

[0019] A blade holder, the top of which is pivotally connected to the sliding arm via a pivot member, the axis of which extends along the X-axis, and the peeling blade is fixed to the bottom of the blade holder;

[0020] The elastic element is a plurality of such elements, which are respectively disposed on both sides of the rotating shaft in the Y-axis direction. The elastic element is located between the sliding arm and the blade holder and is in a compressed state. When the blade holder rotates, the compressed state of the elastic element changes accordingly.

[0021] According to one embodiment of the present invention, the lower end of the sliding arm has two lips arranged opposite to each other in the X-axis direction, and a pivot groove is defined between the two lips;

[0022] The top of the blade holder has a pivot portion, which is located in the pivot groove. The rotating shaft passes through the two lips and the pivot portion along the X-axis to form a pivot connection.

[0023] The elastic element is a compression spring, the lower end of which abuts against the top end of the blade holder, and the upper end of which abuts against the lip.

[0024] According to one embodiment of the present invention, the roller assembly includes:

[0025] An adjustable bracket, which is slidable relative to the stripper plate in the Z-axis direction;

[0026] A roller, which is pivotally mounted on the bottom of the adjustable bracket;

[0027] A locking element is provided to selectively lock and fix the adjustable bracket to the peeler plate so that the height position of the roller in the Z-axis direction is adjustable.

[0028] According to one embodiment of the present invention, the lower end of the first gripper finger has a fingertip portion that bends toward the side of the film-peeling blade assembly;

[0029] The fingertip has a first clamping slope, which is inclined upward in the X-axis direction from the side closest to the film peeling blade assembly to the other side;

[0030] The second clamping finger is located between the first clamping finger and the film-peeling blade assembly, and the lower end of the second clamping finger has a second clamping slope, which is parallel to the first clamping slope.

[0031] The driver is connected to the upper ends of the first and second gripping fingers to drive the first and second gripping fingers to move relative to each other along the Z-axis, so that the first and second gripping inclined surfaces move closer to or further away from each other.

[0032] On the other hand, the flexible sheet assembly equipment according to an embodiment of the present invention has a flexible sheet film tearing mechanism as described above.

[0033] According to the flexible sheet tearing mechanism and flexible sheet assembly equipment provided in the embodiments of the present invention, the tearing gripper assembly can hold the handle of the release film, while the lifting drive device in the tearing blade assembly can drive the blade plate to descend along the Z-axis direction and approach the release film, and move synchronously with the tearing gripper assembly along the X-axis direction during tearing. In this way, by utilizing the blocking effect of the blade plate on the release film, the flexible sheet is prevented from deforming upwards during tearing, ensuring that the flexible sheet is not deformed or even damaged during tearing, thus realizing the reliable and effective automatic tearing of the flexible sheet, and improving the assembly efficiency and quality of the flexible sheet.

[0075] The flexible sheet tearing mechanism and flexible sheet assembly equipment of the present invention are described in detail below with reference to the accompanying drawings.

[0076] Reference Figures 1 to 7 As shown, the flexible sheet film tearing mechanism provided in the embodiment of the present invention is used to remove the release film 40 on the surface of the flexible sheet, and includes a multi-axis robotic arm, a film tearing gripper assembly 20 and a film tearing blade assembly 30.

[0077] Specifically, the multi-axis robotic arm can move in multiple axes, such as the X-axis and Z-axis, and drives the film-tearing gripper assembly 20 and the film-tearing blade assembly 30 to move.

[0078] A film-tearing gripper assembly 20 is mounted on the multi-axis robotic arm to grip the handle of the release film 40 and move along the X-axis direction under the drive of the multi-axis robotic arm to remove the release film 40. During film tearing, the multi-axis robotic arm can first drive the film-tearing gripper assembly 20 to descend to the tearing position, and then the film-tearing gripper assembly 20 can be used to grip the handle 401 of the release film 40.

[0079] The film-peeling blade assembly 30 is mounted on the multi-axis robotic arm and arranged side-by-side with the film-peeling gripper assembly 20 in the X-axis direction. This side-by-side arrangement ensures that when the film-peeling gripper assembly 20 approaches the handle 401 of the release film 40 on the flexible sheet, the film-peeling blade assembly 30 is positioned just above the release film 40. Exemplarily, a mounting base 10 is connected to the lower end of the multi-axis moving arm, and the film-peeling blade assembly and the film-peeling gripper assembly 20 are mounted side-by-side on this mounting base 10 in the X-axis direction.

[0080] The film-peeling blade assembly 30 includes a peeling blade plate 301 and a lifting drive device 302. The peeling blade plate 301 is connected to the lifting drive device 302 so that the lifting drive device 302 drives the peeling blade plate 301 to descend along the Z-axis direction and approach the release film 40. When peeling the film, it moves synchronously with the film-peeling gripper assembly 20 along the X-axis direction.

[0081] In other words, the film-peeling blade assembly 30 mainly consists of a peeling blade 301 and a lifting drive device 302. The lifting drive device 302 can drive the peeling blade 301 to move up and down along the Z-axis. When the peeling blade 301 moves downward, it gradually approaches the release film 40 on the upper surface of the flexible sheet. When the peeling blade 301 moves upward, it gradually moves away from the upper surface of the flexible sheet. Driven by the lifting drive device 302, the peeling blade 301 can be close to the release film 40 below it.

[0082] During the actual film-tearing process, the flexible sheet with release film 40 is located on the fixture table, with the release film 40 on the upper surface of the flexible sheet, and the handle 401 of the release film 40 extending to one side. First, the film-tearing gripper assembly 20 and the film-tearing blade assembly 30 are driven by a multi-axis robotic arm to descend to a predetermined position, and then the film-tearing gripper assembly 20 clamps the handle 401 of the release film 40 on the upper surface of the flexible sheet. Next, the lifting drive device 302 drives the peeling blade 301 to move downward, so that the peeling blade 301 is close to the release film 40. Finally, the multi-axis robotic arm drives the film-tearing gripper assembly 20 and the film-tearing blade assembly 30 to translate along the X-axis towards the side where the film-tearing blade assembly 30 is located. In this way, the film-tearing gripper assembly 20 and the film-tearing blade assembly 30 move synchronously. During this process, since the peeling blade 301 always stays close to the release film 40, when the film-tearing gripper assembly 20 moves to tear off the release film 40, the peeling blade 301 prevents the flexible sheet from bending and deforming upward, thereby maintaining a horizontal state and ensuring that the flexible sheet does not deform during the entire film-tearing process.

[0083] According to the flexible sheet film tearing mechanism provided in the embodiment of the present invention, the film tearing gripper assembly 20 can hold the handle portion 401 of the release film 40, while the lifting drive device 302 in the film tearing blade assembly 30 can drive the peeling blade 301 to descend along the Z-axis direction and approach the release film 40. During film tearing, it moves synchronously with the film tearing gripper assembly 20 along the X-axis direction. In this way, by utilizing the blocking effect of the peeling blade 301 on the release film 40, the flexible sheet material is prevented from deforming upwards during film tearing, ensuring that the flexible sheet material is not deformed or even damaged during film tearing. This achieves reliable and effective automatic film tearing of the flexible sheet material, improving the assembly efficiency and quality of the flexible sheet material.

[0084] Reference Figures 2 to 3 and Figure 7 As shown, in one embodiment of the present invention, the film-tear gripper assembly 20 includes a first gripper finger 201, a second gripper finger 202, and a driver 203, wherein the second gripper finger 202 is disposed opposite to the first gripper finger 201. The driver 203 is connected to the first gripper finger 201 and the second gripper finger 202 to drive the first gripper finger 201 and the second gripper finger 202 to move relative to each other to perform a clamping or releasing action.

[0085] For example, the first gripper 201 and the second gripper 202 are arranged side by side relative to each other in the X-axis direction. The driver 203 is a clamping cylinder. The upper end of the first gripper 201 is fixed on one of the clamping arms of the clamping cylinder, and the upper end of the second gripper 202 is fixed on the other clamping arm of the clamping cylinder. When the clamping cylinder is activated, it can drive the first gripper 201 and the second gripper 202 to move relative to each other, thereby realizing the clamping or releasing action.

[0086] In this embodiment, the first gripper 201 and the second gripper 202 are driven by the driver 203 to move relative to each other and clamp the handle 401 of the release film 40, simulating the gripping action of human fingers. The gripping operation is more flexible and convenient, and it occupies little space and is easy to cooperate with other mechanisms. In addition, the gripping action is reliable and firm.

[0087] Reference Figures 5 to 6 As shown, in one embodiment of the present invention, the peeling blade 301 has a cut H301 on the side adjacent to the film-tearing gripper assembly 20, and the projection of the lower ends of the first gripper finger 201 and the second gripper finger 202 in the Z-axis direction is at least partially located within the cut H301.

[0088] In this embodiment, a cut H301 is provided on the peeling plate 301, and the projections of the lower ends of the first gripper 201 and the second gripper 202 in the Z-axis direction are at least partially located within the cut H301. During the film peeling process, after the lower ends of the first gripper 201 and the second gripper 202 clamp the handle 401 on the release film 40, when the lifting drive device 302 drives the peeling plate 301 to move downward and approach the release film 40, the first gripper 201 and the second gripper 202 are just located within the cut H301. The edge of the peeling plate 301 adjacent to the film peeling gripper assembly 20 can extend to the starting edge of the release film 40. During the movement of the first gripper 201 and the second gripper 202, since the lower ends of the first gripper 201 and the second gripper 202 remain within the cut H301, under this positional relationship, the dynamic tearing force position can always be restricted by the peeling plate 301, thereby achieving a better effect of preventing the flexible sheet material from deforming upward.

[0089] Reference Figure 6 As shown, in one embodiment of the present invention, an elastic element 305 is provided between the peeling plate 301 and the lifting drive device 302 so that the peeling plate 301 can float elastically.

[0090] In this embodiment, this elastic floating structure can, on the one hand, prevent damage to the flexible sheet caused by hard contact between the peeling blade 301 and the release film 40. On the other hand, under the condition of errors in size, assembly, etc., the peeling blade 301 may not be able to maintain an absolutely horizontal state. Therefore, when the peeling blade 301 is not parallel to the flexible sheet, the elastic floating structure can make the peeling blade 301 automatically adapt after being pressed down and keep it attached to the flexible sheet, thereby ensuring a good deformation blocking effect on the flexible sheet during film peeling.

[0091] Reference Figures 1 to 6As shown, in one embodiment of the present invention, the peeling plate 301 is provided with roller assemblies 304 on both sides in the Y-axis direction. The roller assemblies 304 are pivotable about the axis in the Y-axis direction, and the lowest point of the roller surface of the roller assembly 304 is located below the bottom surface of the peeling plate 301, so as to limit the gap H between the bottom surface of the peeling plate 301 and the release film 40.

[0092] When the multi-axis robotic arm drives the film-tearing gripper assembly 20 and the film-tearing blade assembly 30 to descend, the roller assembly 304 contacts the fixture table. Since the lowest point of the roller assembly 304 is located below the bottom surface of the peeling blade 301, a small gap H is formed between the peeling blade 301 and the release film 40. This small gap H does not affect the function of preventing deformation of the flexible sheet, and also ensures that the peeling blade 301 does not contact the flexible sheet, minimizing pressure damage to the flexible sheet and improving the film-tearing quality.

[0093] Reference Figures 2 to 6 As shown, in some embodiments of the present invention, the film peeling blade assembly 30 further includes a sliding arm 31 and a blade plate seat 303. The sliding arm 31 is connected to the lifting drive device 302 so as to be driven to slide in the Z-axis direction by the lifting drive device 302.

[0094] The top of the blade holder 303 is pivotally connected to the sliding arm 31 via a pivot 306. The axis of the pivot 306 extends along the X-axis. The peeling blade 301 is fixed to the bottom of the blade holder 303.

[0095] There are multiple elastic elements 305, which are respectively disposed on both sides of the rotating shaft 306 in the Y-axis direction. The elastic elements 305 are located between the sliding arm 31 and the blade holder 303 and are in a compressed state. When the blade holder 303 rotates, the compression state of the elastic elements 305 changes accordingly. For example, there are four elastic elements 305, which are arranged in pairs. One pair of elastic elements 305 is located on one side of the rotating shaft 306 in the Y-axis direction, and the other pair is located on the other side of the rotating shaft 306 in the Y-axis direction.

[0096] In other words, the peeling blade 301 is fixedly installed at the bottom of the blade holder 303, and the top of the blade holder 303 is pivotally connected to the lower end of the sliding arm 31. The blade holder 303 can rotate around the axis in the Y-axis direction. Since the elastic element 305 is provided on both sides of the rotating shaft 306 in the Y-axis direction, when the blade holder 303 rotates to one side around the axis in the Y-axis direction, the elastic element 305 on that side is compressed. When the blade holder 303 rotates to the other side around the axis in the Y-axis direction, the elastic element 305 on that side is compressed.

[0097] As the lifting drive device 302 drives the sliding arm 31 to slide downward, the blade seat 303 and the peeling blade 301 at the lower end of the sliding arm 31 move downward accordingly. The peeling blade 301 gradually approaches the release film 40 below. When the peeling blade 301 is not parallel to the release film 40, as the peeling blade 301 descends, one end of the peeling blade 301 contacts the release film 40, and the elastic element 305 on that side is compressed, thereby allowing the entire peeling blade 301 to adhere to the release film 40. In this way, the peeling blade 301 has a good deformation blocking effect on the flexible sheet material. This structure, which combines pivot connection and elastic floating, can play a better self-adaptive role and ensure that the peeling blade 301 adheres to the release film 40.

[0098] Reference Figures 2 to 3 and Figures 5 to 6 As shown, in one embodiment of the present invention, the lower end of the sliding arm 31 has two lips 311 arranged opposite to each other in the X-axis direction, and a pivot groove H31 is defined between the two lips 311.

[0099] The top of the blade holder 303 has a pivot portion 3031, which is located in the pivot groove H31. The rotating shaft 306 passes through the two lips 311 and the pivot portion 3031 along the X-axis to form a pivot connection.

[0100] The elastic element 305 is a compression spring. The lower end of the compression spring abuts against the top end of the blade plate seat 303, and the upper end of the compression spring abuts against the lip edge 311.

[0101] In this embodiment, a pivot groove H31 is formed at the lower end of the sliding arm 31, and a pivot part 3031 is provided at the top of the blade plate holder 303. The pivot part 3031 is placed in the pivot groove H31 and a pivot connection is formed through the rotating shaft 306. This kind of cooperation ensures that the blade plate holder 303 is fixed in the X-axis direction and can reliably rotate around the axis in the Y-axis direction. Furthermore, a compression spring is provided between the top of the blade plate holder 303 and the lip edge 311. In this way, not only can the blade plate holder 303 be kept in balance, but also a reliable elastic floating effect can be formed when the blade plate holder 303 rotates.

[0102] Reference Figure 6 As shown, in some embodiments of the present invention, the roller assembly 304 includes an adjustable bracket 3041, a roller 3042 and a locking member. The adjustable bracket 3041 is slidable relative to the peeler plate 301 in the Z-axis direction; the roller 3042 is pivotally mounted on the bottom of the adjustable bracket 3041.

[0103] The locking element is used to selectively lock and fix the adjustable bracket 3041 and the stripper plate 301, so that the height position of the roller 3042 in the Z-axis direction is adjustable. For example, the adjustable bracket 3041 has a strip-shaped hole extending in the vertical direction, the side of the stripper plate holder 303 has a threaded hole, and the locking element is a bolt. The bolt passes through the strip-shaped hole and is threadedly connected to the threaded hole on the stripper plate holder 303. The adjustable bracket 3041 and the stripper plate holder 303 are selectively locked by adjusting the tightness of the bolt.

[0104] When the height of roller 3042 needs to be adjusted, the locking device can be loosened first, and then the adjustable bracket 3041 can be slid up and down to the desired position. Then, the locking device can be used to lock the adjustable bracket 3041 back to the blade holder 303. Since the height of roller 3042 changes, when roller 3042 contacts the fixture table, the gap H between the peeling blade 301 and the release film 40 will also change. In this way, by adjusting the height of roller 3042, the gap H between peeling blade 301 and release film 40 can be adjusted. By adjusting the gap H, the film peeling requirements of different products can be met, making it flexible, convenient and more applicable.

[0105] Reference Figures 2 to 3 and Figure 7 As shown, in one embodiment of the present invention, the lower end of the first gripping finger 201 has a fingertip portion 2011 that bends toward one side of the film-peeling blade assembly 30. The fingertip portion 2011 has a first gripping slope S2a, which is inclined upward in the X-axis direction from one side near the film-peeling blade assembly 30 to the other side.

[0106] The second clamping finger 202 is located between the first clamping finger 201 and the film-peeling blade assembly 30, and the lower end of the second clamping finger 202 has a second clamping slope S2b, which is parallel to the first clamping slope S2a.

[0107] The driver 203 is connected to the upper ends of the first clamping finger 201 and the second clamping finger 202 to drive the first clamping finger 201 and the second clamping finger 202 to move relative to each other along the Z-axis direction, so that the first clamping inclined surface S2a and the second clamping inclined surface S2b move closer to or further away from each other.

[0108] In other words, in this embodiment, the lower ends of the first clamping finger 201 and the second clamping finger 202 respectively form a first clamping inclined surface S2a and a second clamping inclined surface S2b. The first clamping inclined surface S2a and the second clamping inclined surface S2b form an angle with the X-axis direction. In terms of driving method, the first clamping finger 201 and the second clamping finger 202 are driven to move up and down in the Z-axis direction by the driver 203. In this way, when performing the clamping action, the handle part 401 on the release film 40 can be lifted upward. After being lifted, it can be moved along the X-axis direction to tear the film. The clamping position is located above the release film 40, making the film tearing smoother and more reliable.

[0109] The flexible sheet assembly equipment according to an embodiment of the present invention has a flexible sheet film-tearing mechanism as described above. It is understood that the assembly equipment also includes a jig table, an assembly robot, etc., which will not be described in detail here.

[0110] According to the flexible sheet assembly equipment provided in the embodiments of the present invention, the film-tearing gripper assembly 20 can hold the handle portion 401 of the release film 40, while the lifting drive device 302 in the film-tearing blade assembly 30 can drive the peeling blade 301 to descend along the Z-axis direction and approach the release film 40. During film tearing, it moves synchronously with the film-tearing gripper assembly 20 along the X-axis direction. In this way, by utilizing the blocking effect of the peeling blade 301 on the release film 40, the flexible sheet is prevented from deforming upwards during film tearing, ensuring that the flexible sheet is not deformed or even damaged during film tearing. This achieves reliable and effective automatic film tearing of the flexible sheet, improving the assembly efficiency and quality of the flexible sheet.
