Technical Field

[0001] The present application relates to the field of notebook assembly, and in particular to a small iron sheet assembly machine. Background Art

[0002] Small iron sheets are widely used in the manufacturing process of electronic devices such as laptops. These small iron sheets usually have adhesive backing so that they can be fixed in a specific position.

[0003] For example, in the process of assembling a laptop, the DB board and the MB (Main Board) are usually connected through the AB10 board's PIN pins to ensure normal signal transmission. An AB10 iron sheet needs to be mounted at the connection between the AB10 board and the MB to enhance the stability of the connection.

[0004] However, currently the placement of small iron sheets is usually done manually. However, the efficiency of manual placement is low, and the quality of placement varies, and stable placement quality cannot be guaranteed. Summary of the invention

[0005] In order to solve the problem of low efficiency and low quality of small iron sheet mounting, the present application provides a small iron sheet assembly machine.

[0006] The small iron sheet assembly machine provided in this application adopts the following technical solution: A small iron sheet assembly machine, comprising: The feeding assembly is used for conveying small iron sheets, the back of which is provided with adhesive backing, and the adhesive backing is covered with a protective film.

[0007] The film tearing assembly comprises a first recognition unit and a film tearing unit, wherein the first recognition unit is used to recognize the small iron sheet, and the film tearing unit has a grabbing and film tearing state and a mounting state.

[0008] In the grabbing and film-tearing state, the film-tearing unit is used to grab the small iron piece identified by the first identification unit and tear off the protective film on the back of the small iron piece.

[0009] In the mounting state, the film-tearing unit is used to mount the small iron sheet with the protective film torn off on a substrate to which the small iron sheet needs to be attached.

[0010] The identification component is used to identify the position of the substrate in the mounting state, and the relative position of the film tearing unit and the small iron piece grasped by the film tearing unit.

[0011] By adopting the above scheme, the first recognition unit can recognize the small iron sheet conveyed by the feeding component, so that the film-tearing unit can accurately grab the small iron sheet and tear off the protective film on the back of the small iron sheet, so that the adhesive on the back of the small iron sheet is exposed. After the protective film is torn off, the recognition component can recognize the position of the substrate, and can also recognize the relative position of the film-tearing unit and the small iron sheet grabbed by the film-tearing unit, so that the film-tearing unit can move the small iron sheet after the film is torn to a precise position with the substrate, and then accurately mount the small iron sheet on the substrate, completing the automatic and precise mounting of the small iron sheet.

[0012] Preferably, the feeding assembly comprises: A feeding unit is used for conveying the small iron pieces.

[0013] The turning unit is used to turn over the small iron sheet conveyed by the feeding unit, so that the small iron sheet is turned over to a preset posture.

[0014] The first recognition unit is used to recognize the small iron piece in a preset posture.

[0015] By adopting the above solution, the feeding unit can convey an appropriate amount of small iron sheets to the flipping unit, and the flipping unit flips the small iron sheets to a preset posture, so as to facilitate the subsequent film tearing and mounting process of the small iron sheets.

[0016] Preferably, the feeding unit comprises a vibrating feeding tray having a feeding port and a guide portion.

[0017] The turning unit comprises a vibrating turning plate, and the guide portion is used to connect the feeding port and the vibrating turning plate.

[0018] The first identification unit is used to identify the small iron pieces in a preset posture in the vibrating material turning tray, and is also used to identify the total number of the small iron pieces in the vibrating material turning tray.

[0019] By adopting the above scheme, when the first recognition unit recognizes that the total number of small iron pieces in the vibrating material turning tray is less than the preset number, the vibrating feeding tray can feed the material to the vibrating material turning tray by vibration. The vibrating material turning tray flips the small iron pieces to a preset posture by vibration. The first recognition unit recognizes whether there are small iron pieces in a preset posture in the vibrating material turning tray. When there are no small iron pieces in the preset posture, the vibrating material turning tray continues to vibrate and turn the material; when there are small iron pieces in the preset posture, the small iron pieces in the preset posture are recognized, so that the film tearing assembly can accurately grasp the small iron pieces in the preset posture.

[0020] Preferably, the film tearing unit comprises a grabbing and moving module and an auxiliary film tearing module.

[0021] In the film-tearing state, the grabbing and moving module is used to grab the small iron piece identified by the first identification unit and move the small iron piece to the auxiliary film-tearing module.

[0022] The auxiliary film tearing module is used to fix the protective film.

[0023] The grabbing and moving module is also used for relative movement with the auxiliary film-tearing module when the protective film is fixed, so that the protective film on the small iron sheet is torn off.

[0024] By adopting the above solution, the grabbing and moving module can grab the small iron sheet in a preset posture and then transport the small iron sheet to the auxiliary film-tearing module, so that the auxiliary film-tearing module can fix the protective film on the back of the small iron sheet. When the protective film is fixed, the grabbing and moving module and the auxiliary film-tearing module can separate the small iron sheet from the protective film through relative movement, completing the film-tearing process.

[0025] Preferably, the small iron sheet assembly machine also includes a waste film recovery component.

[0026] The waste film recovery component includes a recovery box and a collection generator.

[0027] The recovery box is located below the auxiliary film tearing module, and both upper and lower ends of the recovery box are open.

[0028] The collection generator is communicated with the lower end opening of the recovery box, and the collection generator is used for transporting the protective film in the recovery box.

[0029] By adopting the above solution, the torn protective film can fall into the recovery box for temporary collection. The collection generator can transfer the collected protective film so as to centrally process the discarded protective film.

[0030] Preferably, the auxiliary film tearing module comprises a clamping cylinder, the protective film is provided with a gripping portion, and the clamping cylinder is used to clamp the gripping portion.

[0031] By adopting the above solution, the auxiliary film tearing module clamps the gripping portion of the protective film through the clamping claw cylinder, thereby achieving rapid fixation of the protective film.

[0032] Preferably, the auxiliary film tearing module further comprises a rotating cylinder, and the rotating cylinder is connected to the clamping cylinder.

[0033] By adopting the above solution, the rotating cylinder can drive the clamping cylinder to rotate, thereby changing the posture of the clamping cylinder, so that the clamping cylinder can better cooperate with the grabbing and moving module to perform the film tearing process.

[0034] Preferably, the identification component comprises a second identification unit and a third identification unit.

[0035] The second identification unit is used to identify the relative position of the grabbing and moving module and the small iron piece grabbed by the grabbing and moving module.

[0036] The third identification unit is used to identify the position of the substrate, and the third identification unit is arranged on the grabbing and moving module.

[0037] In the mounting state, the grabbing and moving module is used to mount the small iron sheet with the protective film torn off on the substrate.

[0038] By adopting the above scheme, before the grabbing and moving module mounts the small iron sheet, the second recognition unit can identify the relative position of the grabbing and moving module and the small iron sheet grabbed by the grabbing and moving module, and the third recognition unit can identify the position of the substrate. The grabbing and moving module can accurately drive the small iron sheet to move according to the recognition results of the second recognition unit and the third recognition unit, so that the small iron sheet and the substrate are accurately positioned to ensure that the mounting position of the small iron sheet will not deviate. Among them, the third recognition unit is set on the grabbing and moving module, which can realize the real-time and accurate acquisition of the position information of the substrate during the mounting process, thereby improving the accuracy and reliability of the mounting of the small iron sheet. Specifically, the third recognition unit can dynamically detect the specific position of the substrate with the movement of the grabbing and moving module, ensuring that each mounting can be accurately aligned with the target area, avoiding mounting failure or defective products caused by position deviation. At the same time, this design can also reduce the influence of external environmental factors on the recognition accuracy, and improve the work efficiency and stability of the entire assembly machine.

[0039] Preferably, at least one of the first identification unit, the second identification unit and the third identification unit is a visual identification element.

[0040] By adopting the above solution, it is possible to achieve high-precision recognition of the position of small iron sheets and substrates, ensuring the accuracy and reliability of the film tearing and mounting process. Through the application of visual recognition parts, the automation level and production efficiency of the entire assembly machine are improved, the need for manual intervention is reduced, the error rate is reduced, and product quality is improved.

[0041] The present application identifies the small iron sheet through the first recognition unit, so that the film-tearing unit can accurately grab the small iron sheet identified by the first recognition unit, and tear off the protective film on the small iron sheet to expose the adhesive backing. The recognition component also accurately identifies the position of the substrate, and the relative position of the film-tearing unit and the small iron sheet grabbed by the film-tearing unit, so that the film-tearing unit can accurately complete the positioning between the small iron sheet and the substrate, and mount the small iron sheet on the substrate, effectively solving the problem of low mounting efficiency and poor mounting quality of the small iron sheet.

[0048] The following is combined with Figures 1 to 5 This application is described in further detail.

[0049] like Figure 1 As shown, an embodiment of the present application discloses a small iron sheet assembly machine, including a feeding component 1, a film tearing component 2, an identification component 3, a mounting frame 4 and a control module.

[0050] The feeding assembly 1, the film tearing assembly 2 and the identification assembly 3 are all arranged on the mounting frame 4, and the mounting frame 4 can be made of stainless steel. The feeding assembly 1, the film tearing assembly 2 and the identification assembly 3 are all connected to the control module signal.

[0051] The feeding assembly 1 is used to convey the small iron sheet, thereby completing the feeding. The back of the small iron sheet is provided with a backing adhesive, and the backing adhesive is covered with a protective film. The backing adhesive is used to bond the small iron sheet to the substrate. By tearing off the protective film and exposing the backing adhesive, the small iron sheet can be mounted on the substrate.

[0052] like Figure 1 and Figure 2As shown, the feeding assembly 1 includes a feeding unit 11 and a flipping unit 12. The feeding unit 11 is used to convey small iron sheets for feeding. The flipping unit 12 is used to flip the small iron sheets conveyed by the feeding unit 11, so that the small iron sheets are flipped to a preset posture.

[0053] For example, the feeding unit 11 includes a vibrating feeding tray, and the turning unit 12 includes a vibrating turning tray.

[0054] The vibrating feeding tray has a feeding port and a guide portion, and the guide portion can specifically be an inclined guide plate, and the guide portion is used to connect the feeding port and the vibrating turning tray.

[0055] Both the vibrating feeding tray and the vibrating turning tray can be made to vibrate by arranging a vibrating motor.

[0056] There are many small iron pieces in the vibrating feeding tray. When the vibrating feeding tray vibrates, the small iron pieces inside can enter the vibrating turning tray through the feeding port and the guide part.

[0057] like Figure 2 and Figure 3 As shown, the film tearing assembly 2 includes a first recognition unit 21 and a film tearing unit 22. The first recognition unit 21 can be a large-viewing industrial camera. The first recognition unit 21 can recognize the total number of the small iron pieces in the vibrating turning tray. When the total number of the small iron pieces in the vibrating turning tray is lower than a preset number, the control module can control the vibration feeding tray to vibrate, so that the small iron pieces in the vibrating feeding tray enter the vibrating turning tray.

[0058] The vibrating material turning plate can turn over the small iron sheet inside by vibration, so as to turn the small iron sheet to a preset posture. For example, the state where the front side of the small iron sheet faces upward can be defined as the preset state.

[0059] The film tearing unit 22 has a film grabbing and tearing state and a film mounting state.

[0060] In the grabbing and tearing film state, the first recognition unit 21 can also recognize a small iron sheet in a preset posture in the vibrating material turning tray. When the first recognition unit 21 recognizes that there is no small iron sheet in a preset state in the vibrating material turning tray, the control module can control the vibration turning tray to vibrate until a small iron sheet in a preset state appears in the vibrating material turning tray. When there is a small iron sheet in a preset state in the vibrating material turning tray, the control module can drive the tearing film unit 22 to grab the small iron sheet identified by the first recognition unit 21 according to the position and posture of the small iron sheet identified by the first recognition unit 21, and tear off the protective film on the back of the small iron sheet. After tearing off the protective film, the tearing film unit 22 enters the mounting state.

[0061] In the mounting state, the recognition component 3 can recognize the position of the substrate, and the relative position of the film-tearing unit 22 and the small iron sheet captured by the film-tearing unit 22, so that the control module can control the film-tearing unit 22 to accurately drive the small iron sheet to move according to the recognition result of the recognition component 3, so as to accurately mount the small iron sheet with the protective film torn off on the substrate, and complete the mounting process. Ensure that the mounting position of the small iron sheet will not deviate.

[0062] The embodiment of the present application recognizes the small iron sheet through the first recognition unit 21, so that the film-tearing unit 22 can accurately grab the small iron sheet recognized by the first recognition unit 21, and tear off the protective film on the small iron sheet to expose the adhesive backing. The recognition component 3 also accurately recognizes the position of the substrate, and the relative position of the film-tearing unit 22 and the small iron sheet grabbed by the film-tearing unit 22, so that the film-tearing unit 22 can accurately complete the positioning between the small iron sheet and the substrate, and mount the small iron sheet on the substrate, effectively solving the problem of low mounting efficiency and poor mounting quality of the small iron sheet.

[0063] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the film tearing unit 22 includes a grabbing and moving module 221 and an auxiliary film tearing module 222 .

[0064] In the film tearing state, the grabbing and moving module 221 is used to grab the small iron piece identified by the first identification unit 21 and move the small iron piece to the auxiliary film tearing module 222 .

[0065] The grabbing and moving module 221 may be an industrial robot, such as a four-axis robot. The way in which the four-axis robot grabs the small iron sheet is not strictly limited. For example, a suction cup may be provided on the four-axis robot, and the suction cup is connected to a negative pressure generating part such as an air pump, so that the suction cup can hold the small iron sheet by generating negative pressure. A slide cylinder may be provided on the four-axis robot, and the slide cylinder is connected to the suction cup to assist in driving the suction cup to move.

[0066] like Figure 4 As shown, the auxiliary film tearing module 222 is used to fix the protective film. The auxiliary film tearing module 222 includes a clamping cylinder 2221 and a rotating cylinder 2222.

[0067] The protective film has a gripping portion, which can be a gripping ear extending outside the edge of the small iron sheet. When the gripping moving module 221 moves the small iron sheet to the vicinity of the clamping claw cylinder 2221, the clamping claw cylinder 2221 can clamp the gripping portion. After the protective film is clamped, the gripping moving module 221 and the auxiliary film tearing module 222 can be moved relative to each other, so that the protective film and the small iron sheet can be separated. For example, after the protective film is clamped by the clamping claw cylinder 2221, the protective film can be torn off by making the four-axis robot drive the small iron sheet away from the clamping claw cylinder 2221.

[0068] The rotating cylinder 2222 is connected to the clamping cylinder 2221, and the rotating cylinder 2222 can drive the clamping cylinder 2221 to rotate, thereby changing the posture of the clamping cylinder 2221, so that the clamping cylinder 2221 can better cooperate with the grabbing and moving module 221 to perform the film tearing process.

[0069] like Figure 1 and Figure 4 As shown, in some embodiments, the small iron sheet assembly machine also includes a waste film recovery component 5.

[0070] The waste film recovery component 5 includes a recovery box 51 and a collection generator 52 . The recovery box 51 has openings at both upper and lower ends, and the collection generator 52 is connected to the lower end opening of the recovery box 51 .

[0071] The recovery box 51 is located below the clamping claw cylinder 2221 of the auxiliary film tearing module 222. When the protective film is torn off, the clamping claw cylinder 2221 releases the clamped protective film, and the discarded protective film can fall into the recovery box 51 under the action of gravity.

[0072] The collection generator 52 may be a negative pressure generating member or a conveyor belt, and is used to transport the protective film in the recovery box 51 so as to centrally process the discarded protective film. For example, the collection generator 52 may include a pneumatic conveyor. The pneumatic conveyor creates negative pressure at the lower end opening of the recovery box 51, thereby sucking away and transferring the discarded protective film.

[0073] like Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, the identification component 3 includes a second identification unit 31 and a third identification unit 32 .

[0074] The second identification unit 31 is disposed on the mounting frame 4 , and is used to accurately identify the relative position of the grabbing and moving module 221 and the small iron piece grabbed by the grabbing and moving module 221 .

[0075] The third recognition unit 32 is used to accurately recognize the position of the substrate.

[0076] Specifically, in the mounting state, the grabbing and moving module 221 moves the small iron sheet after the film is torn off to the recognition area of ​​the second recognition unit 31. After the second recognition unit 31 accurately identifies the relative position of the grabbing and moving module 221 and the small iron sheet grabbed by the grabbing and moving module 221, the control module controls the grabbing and moving module 221 to drive the small iron sheet to move to the placement area of ​​the substrate.

[0077] The third identification unit 32 is arranged on the grabbing and moving module 221, so that the third identification unit 32 can dynamically detect the specific position of the substrate as the grabbing and moving module 221 moves. The control module controls the grabbing and moving module 221 to drive the small iron sheet to move according to the identification information of the second identification unit 31 and the third identification unit 32, so that the small iron sheet can be accurately positioned with the substrate, and further mount the small iron sheet on the substrate. Among them, after the identification by the second identification unit 31 and the third identification unit 32, it can be ensured that each mounting can be accurately aligned with the target area, avoiding mounting failure or defective products caused by position deviation.

[0078] Further, at least one of the first recognition unit 21, the second recognition unit 31 and the third recognition unit 32 is a visual recognition component. For example, the first recognition unit 21, the second recognition unit 31 and the third recognition unit 32 can all be industrial cameras, and all three are connected to the control module signal. Taking the second recognition unit 31 as an example, the second recognition unit 31 includes a CCD camera 311, a lens 312 and a light source 313. The lens 312 is installed on the CCD camera 311, and the recognition process is performed by the CCD camera 311. The light source 313 is used to fill in the light during the operation of the CCD camera 311. In addition, since the positioning accuracy is required to be high during the mounting process, the recognition accuracy of the second recognition unit 31 and the third recognition unit 32 is usually higher than the recognition accuracy of the first recognition unit 21. Of course, there is no mandatory limitation on this, and it needs to be based on actual needs.
