[0042] In the tray transfer mechanism, guide rail one and the pallet mainly play a guiding role, and guide rail two and the pallet are in contact with rollers, which have small friction resistance and can ultimately enable the pallet to smoothly translate between guide rails one and two, with relatively high stability.

[0043] After the driving wheel rotates forward and reverse according to the set action, the tray can move back and forth smoothly on the frame, thereby realizing the rapid feeding of the material tray. Its operating efficiency is not only relatively high, but also the feeding is stable, and it has high practical value.

[0044] Since the connection points between the tray and the first guide rail, and between the tray and the second guide rail are all located at the lower part of the tray, the structure is relatively compact.

[0045] Since the material tray can independently translate left and right relative to the frame, after the material tray is moved out by the grabbing assembly, the operator's operation of loading the material tray into the material tray is relatively safe because it is far away from the robot arm. Of course, the corresponding protection effect is also achieved for the robot arm.

[0046] At the same time, since the grabbing component can be raised and lowered according to the actual situation, it can effectively adapt to the material tray with corresponding storage height, and its applicability is relatively high.

[0047] In addition, since the driving component 1 and the driving component 2 are centrally arranged, the entire mechanism occupies relatively less space, the overall structure is relatively high, and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0061] The novel film tearing machine comprises a frame 1, on which a film tearing mechanism, a tray transfer mechanism and a tray collection and lifting mechanism are provided. The film tearing mechanism is used to tear off the protective film on the workpiece, and the tray transfer mechanism can send the workpiece after the film is torn off at the film tearing mechanism to the tray collection and lifting mechanism.

[0062] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 and Figure 7 and Figure 8 and Fig. 9 As shown, the film tearing mechanism includes a frame 1, and also includes a feed channel 23, a bracket 24, a material tape reel 1 25, a material tape reel 26, a film tearing roller 27 and a driving assembly. The above-mentioned feed channel 23 and the bracket 24 are both fixedly connected to the frame 1, and the above-mentioned material tape reel 1 25 and the material tape reel 26 are axially fixed at the two ends of the bracket 24 respectively. Along the feeding direction of the feed channel 23, the above-mentioned material tape reel 1 25 is located at the rear part of the material tape reel 26, and the film tearing roller 27 is movably connected to the lower part of the bracket 24. The tape stored at the material tape reel 1 25 is wound around the film tearing roller 27 and connected to the material tape reel 26. The above-mentioned driving assembly is connected to the bracket 1. In the initial state, the film tearing roller 27 is located directly above the feed channel 23. After the driving assembly drives the film tearing roller 27 to swing, the film tearing roller 27 can move closer to the feed channel 23.

[0063] The workpiece to be torn off passes through the feed channel 23 intermittently.

[0064] The tape reel 1 25 is used for storing the adhesive tape, and the tape reel 2 26 is used for winding up the waste adhesive tape.

[0065] When the workpiece to be torn off at the feeding channel 23 moves to the right below the film-tearing roller 27, the driving assembly drives the film-tearing roller 27 to move downward. Since the adhesive tape is wound around the film-tearing roller 27, the adhesive tape will be closely attached to the workpiece to be torn off, and after the material tape reel 26 is wound up, the film on the workpiece can be stably torn off, and the torn film can be stably taken away with the adhesive tape.

[0066] Once the film tearing operation is completed, the driving assembly resets the film tearing roller 27. The reset film tearing roller 27 moves upward away from the workpiece at the feeding channel 23, waiting for the next workpiece to be film-torn to enter.

[0067] Along the moving direction of the workpiece at the feeding channel 23, the film tearing roller 27, the second material belt reel 26 and the first material belt reel 25 are arranged from front to back.

[0068] A transition roller 28 fixedly connected to the bracket 24 is provided between the second material tape reel 26 and the film tearing roller 27 , and the adhesive tape can be wound around the transition roller 28 .

[0069] The setting of the transition roller 28 can properly tension the adhesive tape to prevent the adhesive tape from being too loose.

[0070] The bracket 24 is also provided with a tensioning assembly, and the tensioning assembly and the first material belt reel 25 are respectively located on both sides of the second material belt reel 26.

[0071] The tensioning assembly can prevent the adhesive tape entering the material reel 26 from being too loose.

[0072] The tensioning assembly includes a fixed roller 29 and a movable roller 30. The fixed roller 29 is fixedly connected to the bracket 24. The movable roller 30 is connected to the bracket 24 through a fastener and the movable roller 30 is adjacent to the fixed roller 29. A material passage for the tape to pass through is formed between the fixed roller 29 and the movable roller 30.

[0073] After the fastener is adjusted, the gap between the movable roller 30 and the fixed roller 29 can be changed accordingly, so that the tension of the tape can be properly adjusted, and corresponding adjustments can be made according to different operating requirements, effectively improving its applicability.

[0074] The driving assembly includes a film tearing cylinder 31, a rocker arm 32 and a roller seat 33. The middle part of the roller seat 33 is hinged on the bracket 24. The film tearing roller 27 is movably connected to the outer end of the roller seat 33. The middle part of the rocker arm 32 is hinged on the bracket 24. The film tearing cylinder 31 is fixedly connected to the bracket 24 and the piston rod of the film tearing cylinder 31 is directly opposite to one end of the rocker arm 32. The other end of the rocker arm 32 is located at the inner end of the roller seat 33. The roller seat 33 has a tendency to swing down to its inner end and abut against the other end of the rocker arm 32 under the action of its own gravity.

[0075] In the initial state, the film-tearing roller 27 on the roller seat 33 is away from the feeding channel 23 .

[0076] After the film tearing cylinder 31 presses the swing rod 32, the swing rod 32 presses the roller seat 33. After the roller seat 33 is pressed, the film tearing roller 27 thereon swings down to the feeding channel 23, thereby driving the adhesive tape to be stably attached to the workpiece to be torn.

[0077] The frame 1 also has a material moving assembly for grabbing the workpiece after film tearing and turning the grabbed workpiece over.

[0078] The workpiece after the film is torn can be stably moved out from the feeding channel 23 by the material moving assembly. And the workpiece after being moved out is turned over to facilitate the robot to grab it in the subsequent process.

[0079] The material moving assembly includes a material moving block 34, a slide plate 1 35, a slide plate 2 36, a driving member 1 37 and a driving member 2 38. The material moving block 34 is in the shape of a long block and is fixedly connected to the frame 1. The slide plate 1 35 is connected to the upper part of the material moving block 34. The driving member 1 37 is fixedly connected to the material moving block 34 and the driving member 1 37 can drive the slide plate 1 35 to translate along the material moving block 34. The slide plate 2 36 is connected to the slide plate 1 35. The driving member 2 38 is fixedly connected to the slide plate 1 35 and the driving member 2 38 can drive the slide plate 2 36 to translate along the slide plate 1 35. The slide plate 1 35 is also connected to a vacuum suction cup 39 for grabbing a workpiece. A transmission mechanism is provided between the slide plate 1 35 and the slide plate 2 36, which can flip the vacuum suction cup 39 when the slide plate 2 36 moves relative to the slide plate 1 35.

[0080] The transmission mechanism includes a rotating shaft 40, a transmission gear 41 and a rack 42. The vacuum suction cup 39 includes a frame-shaped body 39a and a suction cup 39b fixedly connected to the body 39a. The rotating shaft 40 is fixedly connected to the body 39a and the transmission gear 41 is located in the middle of the rotating shaft 40. The rotating shaft 40 is axially fixedly connected to the slide 1 35 and the rotating shaft 40 can rotate relative to the slide 1 35. The rack 42 is fixedly connected to the slide 2 36 and the rack 42 is meshed with the transmission gear 41.

[0081] The vacuum suction cup 39 is used to grab the workpiece after the film is torn off.

[0082] After the driving member 1 37 drives the slide plate 1 35 and the slide plate 2 36 to move together, the vacuum suction cup 9 and the film-torn workpiece grasped can be stably withdrawn from the feeding channel 23.

[0083] At this time, the driving member 2 38 drives the slide plate 2 36 to move independently. The vacuum suction cup 39 is turned over under the action of the transmission gear 41 and the rack 42. After turning over, the grasped workpiece faces upward, which is convenient for the robot hand of the subsequent process to grasp it.

[0084] In this embodiment, the flip angle of the vacuum suction cup 39 is 180 degrees.

[0085] The above-mentioned feeding channel 23, bracket 24, material tape reel 1 25, material tape reel 26, film tearing roller 27 and driving assembly form a film tearing unit, and the number of the said adsorption disk 39b is two, and the two adsorption disks 39b are respectively connected to the left and right ends of the main body 39a, and each adsorption disk 39b corresponds to a film tearing unit.

[0086] One material moving assembly corresponds to two film tearing units, thus simplifying the structure of the whole machine and appropriately reducing its cost.

[0087] The film tearing mechanism can quickly complete the film tearing operation after the workpiece to be torn off moves intermittently along the feeding channel, and has a relatively high degree of automation and high operating efficiency.

[0088] At the same time, the material transfer component corresponds to the coordinated action of the two film tearing units, which not only further improves its operating efficiency, but also makes the workpiece after film tearing easier to be grasped by the robot in subsequent processes, and its discharge stability is also relatively high.

[0089] In addition, the material moving assembly is arranged adjacent to the corresponding two film tearing units, and the structure of the whole machine is relatively compact, which has high practical value.

[0090] The material tray transfer mechanism comprises a frame 1 and a material tray located on the frame 1 .

[0091] The transfer mechanism also includes a tray 13, a guide rail and a transmission belt assembly. The tray 13 is frame-shaped and a mounting portion for supporting and positioning the material tray is formed inside the tray 13. The edge of the tray 13 is connected to the guide rail, and the transmission belt assembly is connected to the frame 1. The tray 13 is connected to the transmission belt assembly and the transmission belt assembly can drive the tray 13 to translate along the guide rail.

[0092] After the transmission belt assembly drives the tray 13 to translate on the guide rail, since a corresponding material tray is positioned at the mounting portion of the tray 13, rapid transportation of the material tray is achieved.

[0093] The frame 1 has two guide rails: guide rail 1 14 and guide rail 2 15 . The guide rail 1 14 and guide rail 2 15 are symmetrically arranged in parallel on the frame 1 . One edge of the tray 13 is connected to the guide rail 1 14 , and the other edge of the tray 13 is connected to the guide rail 2 15 .

[0094] The guide rail 14 and the guide rail 2 15 support and guide the two edges of the tray 131 respectively, so as to ensure that the tray 13 can move smoothly along the guide rails.

[0095] The transmission belt assembly includes a driving wheel 16, a driven wheel 17 and a transmission belt 18. The driving wheel 16 and the driven wheel 17 are axially fixed on the frame 1. The transmission belt 18 is sleeved on the driving wheel 16 and the driven wheel 17. The driving wheel 16 is used to be connected to a driving member that can drive it to rotate continuously. The tray 13 is connected to the transmission belt 18.

[0096] The driving member is a motor, and when the driving member drives the driving wheel 16 to rotate, the transmission belt 18 will move steadily. Since the tray 13 is fixedly connected to the transmission belt 18, the tray 13 can be translated stably in the end.

[0097] A block-shaped positioning block 13a is fixedly connected to the tray 13, a plate-shaped positioning plate 19 is fixedly connected to the driving belt 18, the positioning plate 19 is fixedly connected to the positioning block 13a by fasteners, and the driving belt 18 is tightly pressed against the positioning plate 19 and the positioning block 13a.

[0098] After the transmission belt 18 is tightly pressed against the positioning plate 19 and the positioning block 13 a , the tray 13 can be stably fixed on the transmission belt 18 .

[0099] The positioning plate 19 is in the shape of a long plate, and has a plurality of protruding pressing edges 19 a at the lower part of the positioning plate 19 along its length direction. The transmission belt 18 is tightly pressed between the plurality of pressing edges 19 a and the positioning block 13 a.

[0100] The multiple protruding pressure edges 19 a can be embedded in the transmission belt 18 , thereby improving the connection stability between the transmission belt 18 and the tray 13 .

[0101] A guide bar 20 is fixedly connected to the lower portion of one edge of the tray 13 . The lower portion of the guide bar 20 has a guide rail groove 20 a matching the guide rail 14 . The guide bar 20 is embedded in the guide rail groove 20 a of the guide bar 20 .

[0102] The guide rail 14 is embedded in the guide rail groove 20 a of the guide bar 20 . Such a structure enables the guide rail 14 to guide the tray 13 stably.

[0103] The tray 13 has a roller 21 at the lower portion of the other edge thereof, and the roller 21 abuts against the upper portion of the second guide rail 15 .

[0104] The friction resistance between the roller 21 and the second guide rail 15 is relatively small, and such a structure can make the tray 13 translate smoothly.

[0105] That is to say, the guide rail 1 14 plays a guiding role, and the guide rail 2 15 plays a role in supporting the tray 13 and reducing friction resistance.

[0106] There are a plurality of rollers 21 , which are evenly distributed along the length direction of the second guide rail 15 .

[0107] The arrangement of the plurality of rollers 21 can ensure that the connection between the guide rail 2 15 and the tray 13 is more stable.

[0108] The connecting piece 22 is a sheet-shaped connecting piece 22, the lower end of which is fixedly connected to the guide rail 15, and the upper end of which is used to fix the position sensor.

[0109] The position sensor can accurately detect the current position of the tray 13 on the rack 1 , thereby effectively improving the travel accuracy of the tray 13 .

[0110] There are a plurality of connecting pieces 22 , and the connecting pieces 22 are evenly distributed along the length direction of the second guide rail 15 .

[0111] Since each connecting piece 22 is connected to a position sensor corresponding thereto, the arrangement of multiple connecting pieces 22 effectively improves the movement accuracy of the tray 13 .

[0112] In the material tray transfer mechanism, the guide rail 1 and the pallet mainly play a guiding role, and the guide rail 2 and the pallet are in contact with rollers, which have small friction resistance and can ultimately enable the pallet to smoothly translate between the guide rails 1 and 2, with relatively high stability.

[0113] At the same time, after the active wheel rotates forward and reverse according to the set action, the tray can move back and forth smoothly on the frame, thereby realizing the rapid feeding of the material tray. Its operating efficiency is not only relatively high, but also the feeding is stable, and it has high practical value.

[0114] In addition, since the connection points between the tray and the first guide rail, and between the tray and the second guide rail are all located at the lower part of the tray, the structure is relatively compact.

[0115] The material tray collection and lifting mechanism includes a frame 1, and also includes a material tray rack 2, a grabbing assembly 3, a driving assembly 1 and a driving assembly 2. A guide assembly is provided between the lower end of the material tray rack 2 and the frame 1. The driving assembly 1 is arranged between the frame 1 and the lower end of the material tray rack 2. Under the action of the driving assembly 1, the material tray rack 2 can translate left and right relative to the frame 1. The driving assembly 2 is arranged between the frame 1 and the grabbing assembly 3. The driving assembly 2 can drive the grabbing assembly 3 to move up and down relative to the frame 1. In the initial state, the grabbing assembly 3 is located directly above the material tray rack 2. When the driving assembly 1 drives the material tray rack 2 to move, the material tray rack 2 can be moved out from directly below the grabbing assembly 3.

[0116] The driving component 1 and the driving component 2 are two independent components, that is, the material tray rack 2 can independently move left and right relative to the frame 1, and the grabbing component 3 can independently move up and down relative to the frame 1.

[0117] After the tray rack 2 moves, the tray rack 2 can be moved out of the frame 1 and away from the grab assembly 3. Once the tray rack 2 is moved out, the operator can load the tray into the tray rack 2 conveniently and in a safe working environment.

[0118] After the stacking operation of the trays at the tray rack 2 is completed, the tray rack 2 is moved again to the position directly below the grabbing assembly 3 under the action of the driving assembly 1. After a period of operation, the highest position of the stacked trays will become lower and lower. At this time, the driving assembly 2 drives the grabbing assembly 3 to perform the corresponding action matched with it, so that the grabbing assembly 3 can still stably grab the trays.

[0119] The tray rack 2 includes a bottom plate 2a and a bracket 2b fixedly connected to the upper portion of the bottom plate 2a. The bracket 2b is used to store stacked trays. The guide assembly is located between the bottom plate 2a and the frame 1.

[0120] The bottom plate 2a serves as a connecting guide, and the bracket 2b serves as a loading tray. It can be seen that the bottom plate 2a and the bracket 2b serve as independent functions, which effectively improves the stability of the entire tray rack 2.

[0121] The guide assembly includes an upper guide plate 4 and a lower guide plate 5. The upper guide plate 4 is fixedly connected to the frame 1. The inner edge of the lower part of the upper guide plate 4 has a recessed guide groove 4a. The outer edge of the bottom plate 2 is embedded in the guide groove 4a. The lower guide plate 5 is fixedly connected to the frame 1 and the lower guide plate 5 rests on the bottom plate 2a.

[0122] Under the action of the upper guide plate 4 and the lower guide plate 5, the material tray frame 2 can eventually move smoothly left and right.

[0123] The bottom of the bottom plate 2 a has a connection plate 6 protruding downward, the lower guide plate 5 abuts against the inner side of the connection plate 6 , and the upper guide plate 4 is located at one end of the outer side of the connection plate 6 .

[0124] The connecting plate 6 contacts the lower guide plate 5 with a relatively large contact area, thereby improving the guiding stability.

[0125] At the same time, the upper guide plate 4 and the lower guide plate 5 are respectively located on both sides of the connecting plate 6, which further improves the guiding stability and ensures that the material tray frame 2 can move smoothly left and right.

[0126] There are two connecting plates 6 , which are symmetrically arranged on both sides of the bottom plate 2 a . The frame 1 has lower guide plates 5 corresponding to the connecting plates 6 one by one.

[0127] Such a structure further increases the contact area, and ultimately ensures that the material tray rack 2 can translate left and right more stably.

[0128] The first driving component is a transversely arranged cylinder 7, a cylinder body of the cylinder 7 is fixedly connected to the frame 1, and a piston rod of the cylinder 7 is fixedly connected to the bottom plate 2a.

[0129] The cylinder 7 can stably drive the bottom plate 2a to translate.

[0130] The driving assembly includes a motor 8, a screw rod 9 and a base plate 10. The screw rod 9 is vertically arranged and axially fixed on the frame 1. The rotating shaft of the motor 8 is fixedly connected to the screw rod 9. The base plate 10 is connected to the screw rod 9 and is located on the upper part of the bracket 2b. The grabbing assembly 3 is connected to the base plate 10. In this embodiment, the grabbing assembly 3 is a manipulator.

[0131] When the motor 8 drives the screw rod 9 to rotate continuously, the base plate 10 can move up and down smoothly because the base plate 10 is threadedly connected to the screw rod 9 .

[0132] A cylindrical connecting tube 11 is fixedly connected to the end of the base plate 10 . The connecting tube 11 is sleeved on the screw rod 9 and the two are threadedly connected.

[0133] The connecting tube 11 can effectively improve the connection stability between the connecting tube 11 and the screw rod 9 .

[0134] The screw rod 9 and the connecting tube 11 form a lifting assembly. There are several lifting assemblies, and the motor 8 is connected to the screw rod 9 in one of the lifting assemblies.

[0135] Multiple lifting components share one motor, and such a structure can ensure that the substrate 10 moves up and down more smoothly.

[0136] There are several material tray racks, each material tray rack 2 has a one-to-one corresponding drive component 1, and there are one drive component 2 and one grabbing component 3. A fixed plate 12 is fixedly connected to the edge of the base plate 10, and several connecting tubes 11 are evenly distributed along the length direction of the fixed plate 12 and the connecting tubes 11 are fixedly connected to the fixed plate 12.

[0137] Such a structure not only improves the compactness of the structure, but also simplifies the structure of the entire mechanism, ensuring that the cost is moderate and the structure is compact while the stability of the entire mechanism is relatively high.

[0138] In the present tray collection and lifting mechanism, since the tray can independently translate left and right relative to the frame, after the tray is moved out by the grabbing assembly, the operator's operation of loading the tray into the tray is relatively safe because the operator is far away from the manipulator. Of course, the manipulator is also protected accordingly.

[0139] At the same time, since the grabbing component can be raised and lowered according to the actual situation, it can effectively adapt to the material tray with corresponding storage height, and its applicability is relatively high.

[0140] In addition, since the driving component 1 and the driving component 2 are centrally arranged, the entire mechanism occupies relatively less space, the overall structure is relatively high, and has high practical value.
