Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and in particular relates to an automatic detection, positioning and film sticking device. Background Art

[0002] In production operations, it is often necessary to attach protective films to the surfaces of small parts. However, in the existing technology, the film is usually attached manually, which is inefficient. For this reason, film attaching equipment for automatic film attaching has appeared on the market. This type of film attaching equipment is mainly composed of a film supply machine and a robot. The film supply machine is used to convey the film tape, so that the protective film sheets installed on the film tape are moved one by one to the loading station, and the material suction cup on the robot will absorb the protective film at the loading station and transfer it to the workpiece at the operating station for attachment, which has high work efficiency.

[0003] However, in actual use, it was found that the protective film transported by the film supply machine to the loading station may be offset, or the workpiece at the operating station may also be offset. This will cause the protective film sucked by the robot to be offset from the workpiece, resulting in the protective film being unable to be accurately aligned and attached to the workpiece, resulting in a low yield rate.

[0036] Specifically, when in use, the protective film sheets on the film belt are transported one by one to the loading station 10 by the film feeding machine 1, and the workpiece is placed at the operating station 20 by a conveyor belt (not shown) or manually by a worker; then, the driving unit 21 drives the suction cup 22 to move along the Z axis to suck up the protective film sheet at the loading station 10, and the driving unit 21 drives the suction cup 22 to move along the X axis to move the protective film sheet to the first identifier 31; at this time, the first identifier 31 identifies the position information of the sucked protective film sheet and feeds it back to The driving unit 21 is provided with a second identifier 32, which identifies the position information of the workpiece at the operating station 20 and feeds it back to the driving unit 21. The driving unit 21 performs comparative analysis based on the position information of the protective film and the position information of the workpiece to drive the suction cup 22 to rotate around the α axis, thereby adjusting the position of the protective film. Finally, the driving unit 21 continues to drive the suction cup 22 to move along the X axis, so that the protective film is accurately aligned with the workpiece. The driving unit 21 then drives the suction cup 22 to move along the Z axis, so that the protective film can be accurately attached to the workpiece.

[0037] In summary, the utility model provides a film supply machine 1 for conveying protective film sheets one by one, provides a visual recognition unit 3 for identifying protective film sheets and workpieces, and feeds back the position information of the protective film sheets and the workpieces to the driving unit 21, so that the driving unit 21 adjusts the position of the suction cup 22, thereby enabling the protective film sheets to be accurately aligned and attached to the workpiece; therefore, the above-mentioned structures are used in combination to ensure high work efficiency and improve the yield rate.

[0038] See attached Figure 1 -Attached Figure 7 There are various types of driving units 21, which are not limited in the present invention. For ease of understanding, in this embodiment, the driving unit 21 includes a moving part 211, a carrier 212, a vertical driving member 213 and a steering driving member 214; the moving part 211 is driven and connected to the carrier 212 to drive the carrier 212 to move along the X-axis; the vertical driving member 213 is installed on the carrier 212 and is driven and connected to the steering driving member 214 to drive the steering driving member 214 to move along the Z-axis; the steering driving member 214 is driven and connected to the suction cup 22 to drive the suction cup 22 to rotate around the α-axis; the visual recognition unit 3 is electrically connected to the moving part 211 and the steering driving member 214.

[0039] Specifically, when in use, the moving part 211 drives the carrier 212 to move along the X-axis, so that the suction cup 22 moves to the loading station 10, and then the vertical driving part 213 drives the steering driving part 214 to move downward, so that the suction cup 22 absorbs the protective film; after the vertical driving part 213 drives the suction cup 22 to move upward, so that the protective film is separated from the loading station 10, the visual recognition unit 3 feeds back the position information of the protective film and the workpiece to the steering driving part 214, so that the steering driving part 214 drives the suction cup 22 to rotate around the α axis, and then adjusts the position of the protective film so that the position of the protective film is adapted to the position of the workpiece; then, the moving part 211 moves the suction cup 22 along the X-axis to the operating station 20 according to the information fed back by the visual recognition unit 3, so that the protective film after the adjustment is accurately aligned with the workpiece, and finally, the vertical driving part 213 drives the suction cup 22 to move downward, so that the protective film can be accurately attached to the workpiece.

[0040] See attached Figure 1 -Attached Figure 7 The driving unit 21 also includes a longitudinal driving member 215, the moving part 211 is driven and connected to the longitudinal driving member 215 to drive the longitudinal driving member 215 to move along the X-axis; the longitudinal driving member 215 is driven and connected to the carrier 212 to drive the carrier 212 to move along the Y-axis; the visual recognition unit 3 is electrically connected to the longitudinal driving member 215.

[0041] Specifically, during use, the vertical drive 213 drives the suction cup 22 to move upward, so that the protective film is separated from the loading station 10, and the visual recognition unit 3 synchronously feeds back the position information of the protective film and the workpiece to the steering drive 214 and the longitudinal drive 215. The steering drive 214 drives the suction cup 22 to rotate around the α axis, and the longitudinal drive 215 drives the suction cup 22 to move along the Y axis to further adjust the position of the protective film so that the protective film can adapt to the workpiece more accurately.

[0042] See attached Figure 1 -Attached Figure 7The moving part 211 includes a bracket 2111, a first guide rail 2112, a first guide block 2113 and a first screw motor 2114. The first guide rail 2112 is mounted on the bracket 2111 and extends along the X-axis. The first guide block 2113 is slidably mounted on the first guide rail 2112. The first screw motor 2114 is mounted on the first guide rail 2112 and is drivingly connected to the first guide block 2113 to drive the first guide block 2113 to slide along the first guide rail 2112. The longitudinal driving member 21 The second guide rail 2151 includes a second guide block 2152 and a second lead screw motor 2153. The second guide rail 2151 is mounted on the first guide block 2153 and extends along the Y-axis. The second guide block 2152 is slidably mounted on the second guide rail 2151. The second lead screw motor 2153 is mounted on the second guide rail 2151 and is drivingly connected to the second guide block 2152 to drive the second guide block 2152 to slide along the second guide rail 2151. The carrier 212 is mounted on the second guide block 2152.

[0043] Specifically, the visual recognition unit 3 synchronously feeds back the position information of the protective film and the workpiece to the first screw motor 2114 and the second screw motor 2153. The first screw motor 2114 drives the first guide block 2113 to move along the first guide rail 2112, so that the carrier 212 moves in the X-axis, ensuring that the protective film can be aligned with the protective film in the X-axis direction; the second screw motor 2153 drives the second guide block 2152 to move along the second guide rail 2151, so that the carrier 212 moves in the Y-axis, ensuring that the protective film can be aligned with the protective film in the Y-axis direction.

[0044] See attached Figure 1 -Attached Figure 7 The vertical driving component 213 includes a third guide rail 2131, a third guide block 2132, a first servo motor 2133 and a transmission belt 2134. The third guide rail 2131 is mounted on the carrier 212 and extends along the Z axis. The third guide block 2132 is slidably mounted on the third guide rail 2131; two rotating wheels 2135 are also rotatably mounted on the carrier 212, the transmission belt 2134 is wound around the two rotating wheels 2135 and connected to the third guide block 2132, the first servo motor 2133 is mounted on the carrier 212 and is driven and connected to any one of the rotating wheels 2135 to drive the third guide block 2132 to slide along the third guide rail 2131; the steering driving component 214 is a second servo motor, which is vertically mounted on the third guide block 2132 and connected to the suction cup 22 to drive the suction cup 22 to rotate around the α axis.

[0045] Specifically, the first servo motor 2133 drives the rotating wheel 2135 to rotate, thereby causing the third guide block 2132 to move along the third guide rail 2131 to facilitate the suction cup 22 to move up and down along the Z axis; the visual recognition unit 3 synchronously feeds back the position information of the protective film and the workpiece to the second servo motor, and the second servo motor drives the suction cup 22 to rotate around the α axis at a suitable angle to ensure that the protective film is aligned with the protective film.

[0046] See attached Figure 1 -Attached Figure 7 The visual recognition unit 3 further includes a detector 33, which is disposed beside the operating station 20 to detect whether the protective film on the workpiece is adsorbed in place; therefore, the design of the detector 33 can accurately screen out defective products.

[0047] See attached Figure 1 -Attached Figure 7 The first identifier 31, the second identifier 32 and the detector 33 are of various types, and the present invention does not impose any restrictions on this. For ease of understanding, in this embodiment, the first identifier 31, the second identifier 32 and the detector 33 all use visual cameras. The first identifier 31 and the second identifier 32 can respectively photograph and analyze the position information of the protective film and the workpiece, and transmit the information to the drive unit 21, so that the drive unit 21 drives the suction cup 22 to adjust the position of the protective film; the detector 33 can photograph and analyze the workpiece with the protective film adsorbed on it to detect defective products.

[0048] Among them, visual cameras are existing products, which are generally used in conjunction with compatible systems. The relevant technologies are relatively conventional, so there is no restriction on this here.

[0049] See attached Figure 1 -Attached Figure 7 The film supply machine 1 is an existing product. For ease of understanding, in this embodiment, the film supply machine 1 includes a body 11, on which are provided a receiving wheel 12, a supporting platform 13, a partition 14, a feed roller 15, a winding roller 16 and a drive assembly 17; the receiving wheel 12 is used to install the film roll, and the supporting platform 13 and the partition 14 are mutually enclosed to form an isolation gap 130, and the drive assembly 17 is synchronously driven and connected with the feed roller 15 and the winding roller 16.

[0050] Specifically, when in use, the film tape roll is installed on the receiving wheel 12 of the film supply machine 1 body, and the film tape is pulled out and passed through the loading station 10 and the feed roller 15 in sequence, and fixed on the winding roller 16. Then, the driving unit 21 is started to drive the feed roller 15 and the winding roller 16 to rotate synchronously, so as to drive the film tape to move, so as to transfer the protective film sheet to the loading station 10 for use, while the winding roller 16 reels the discarded film tape at the same time.

[0051] See attached Figure 1 -Attached Figure 7The film feeding machine 1 also includes an adjusting unit 18, which includes a fixed seat 181, a fixed frame 182 and an elastic member 183; the fixed seat 181 is mounted on the machine body 11 and is located next to the feed roller 15; a pressing roller 184 is rotatably mounted on the fixed frame 182, and a guide rod 1820 is provided on the fixed frame 182 which is slidably connected to the fixed seat 181, so that the pressing roller 184 can be away from the feed roller 15; the two ends of the elastic member 183 respectively abut the fixed seat 181 and the fixed frame 182, and when the pressing roller 184 is away from the feed roller 15, the elastic member 183 deforms and stores energy.

[0052] Specifically, in the process of winding the waste film tape, the pressure roller 184 squeezes the waste film tape under the action of the elastic member 183 to ensure the stable movement of the waste film tape by increasing the friction force. If there is a missing protective film sheet on the waste film tape, the protective film sheet will apply pressure to the pressure roller 184 when passing through the feed roller 15, so that the pressure roller 184 moves to avoid the position and provide a passage space to ensure that the protective film sheet can pass smoothly; and after the protective film sheet passes smoothly, the elastic member 183 that has deformed and stored energy returns to its original state to drive the pressure roller 184 to reset, so as to increase the friction force on the waste film tape again.

[0053] In summary, the present invention designs a pressure roller 184 to be used in conjunction with the feed roller 15 to increase the friction on the waste film strip, ensuring that the waste film strip can move stably; and since the fixed frame 182 on which the pressure roller 184 is installed is slidably connected to the fixed seat 181, the use of the elastic member 183 will enable the pressure roller 184 to have a avoidance function, ensuring that the missed protective film sheet can also smoothly pass through the gap between the pressure roller 184 and the feed roller 15, solving the problem that the waste film strip is easily retained and accumulated.

[0054] See attached Figure 1 -Attached Figure 7 The adjustment unit 18 also includes a slider 185 and a driving bolt 186. A slide groove 19 is provided on the main body of the film supply machine 1. The slider 185 is arranged on the fixed seat 181 and is slidably connected to the slide groove 19. The driving bolt 186 is rotatably mounted on the machine body 11, and one end of the driving bolt 186 extends into the slide groove 19 and is threadedly connected to the slider 185.

[0055] Among them, if the elastic potential energy of the elastic part 183 is too large, it will drive the pressure roller 184 to tightly squeeze and fit the feed roller 15, resulting in the film strip being unable to pass smoothly, but if the elastic potential energy of the elastic part 183 is too small, it will not be able to increase the friction force on the discarded film; and by setting the adjustment part and the driving part at the same time, it is possible to adjust the distance between the pressure roller 184 and the feed roller 15 without changing the elastic potential energy of the elastic part 183.

[0056] Specifically, when in use, the elastic potential energy of the elastic member 183 is first adjusted through the adjustment part, then the thickness of the discarded film is measured, and the position of the fixing seat 181 is adjusted through the driving part, and then the distance between the pressing roller 184 and the feeding roller 15 is adjusted; therefore, the coordinated use of the adjustment part and the driving part can not only improve the adaptability to adapt to film strips of different thickness specifications, but also make the pressing roller 184 accurately fit the discarded film strip.

[0057] It should also be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
