Description

Technical Field

[0001] This specification relates to the field of automation equipment technology, and in particular to a workpiece thin film separation mechanism. Background Technology

[0002] In the automated production of electronic products, it is often necessary to remove multiple workpieces (such as optical lenses, light guide plates, sealing rings, and small electronic components) attached to thin films (such as protective films and release films) one by one for subsequent mounting, testing, or assembly operations. The core challenge of this process lies in how to quickly and reliably separate the workpieces from the film and efficiently complete the individual removal of materials.

[0003] Existing workpiece handling methods primarily employ vacuum suction cups to directly pick up workpieces from a film. However, this direct suction method has significant limitations: the film possesses a certain degree of flexibility and adhesion, resulting in a tight bond between the workpiece and the film. Direct suction often requires considerable suction force to separate the workpiece from the film, but excessive suction can easily cause the workpiece to bounce off or be damaged during the suction process. Furthermore, due to the elasticity of the film itself, it undergoes localized deformation when the suction cup picks up the workpiece, requiring the suction cup to wait for the film to recover and stabilize before removing the workpiece. This waiting period severely limits the improvement of the handling speed. In addition, when workpieces are densely packed on the film, direct suction can easily cause adhesion or interference between adjacent workpieces, further reducing handling efficiency and success rate. To overcome these problems, existing technologies have attempted to use air-blowing assistance and mechanical ejection to aid in the separation of workpieces from the film. However, these solutions either increase the complexity and cost of the equipment or damage the film and workpiece, and still cannot meet the cycle time requirements of high-speed production lines in terms of handling continuity.

[0004] Therefore, how to achieve rapid and reliable separation of the workpiece and the film without waiting for the film to rebound or damaging the workpiece, and how to enable continuous uninterrupted material handling by the material handling chuck to significantly improve material handling efficiency, has become a technical problem that urgently needs to be solved in this field.

[0008] In a preferred embodiment, when the first driving member and the third driving member are started simultaneously, the third driving member drives the take-up roll to unload the material, and the first driving member drives the moving axis to move towards the second end.

[0009] In a preferred embodiment, the material handling component includes: The first slide rail extends along the first direction; A first mounting plate that is slidably connected to the first slide rail; A second slide rail extending vertically is fixedly mounted on the first mounting plate; A second mounting plate is slidably connected to the second slide rail; the second mounting plate is fixedly connected to a plurality of the material-picking suction cups spaced apart in a second direction.

[0010] In a preferred embodiment, the first slide rail is located on one side of the support platform in the second direction and is disposed near the second end; the second slide rail is located above the support platform; the first mounting plate is connected to a fourth driving member for driving the first mounting plate to move in the first direction; the second mounting plate is connected to a fifth driving member for driving the second mounting plate to move in the vertical direction.

[0011] In a preferred embodiment, the second mounting plate is provided with a third slide rail extending along a second direction, and a plurality of the material-picking suction cups are slidably connected to the third slide rail; the material-picking suction cups are connected to a sixth driving member for driving the material-picking suction cups to move along the second direction.

[0012] In a preferred embodiment, a timing belt is provided on the inner side of the fixing frame, and a drive shaft is connected to one end of the timing belt away from the second end. The drive shaft is connected to a first drive member. The first drive member is used to drive the drive shaft to rotate around a third rotation axis extending in the second direction, so as to drive the timing belt to move along the first direction. The two ends of the moving shaft along the second direction are respectively fixedly connected to the two timing belts.

[0013] In a preferred embodiment, the support platform is provided with a heating component near the second end for heating the film and the workpiece.

[0014] In a preferred embodiment, the second end is provided with a separation block, the upper surface of the separation block is provided with a sunken step, and the higher side of the sunken step is located at the second end; the side of the separation block is an inclined surface, and the inclined surface gradually moves away from the second end from top to bottom.

[0016] Beneficial effects

[0017] The workpiece film separation mechanism provided in this embodiment comprises two fixed frames extending in a first direction and spaced apart in a second direction, and a movable shaft extending in the second direction between them (connected to a first driving member to drive it to move in the first direction), a support platform (having opposing first and second ends) fixedly mounted above the fixed frames, a feed roll and a take-up roll disposed below the fixed frames (the tape of the feed roll enters the support platform through the first end of the support platform, then winds around the movable shaft through the second end, and finally reaches the take-up roll; the tape on the support platform is adhesive-side up to adhere to the film with multiple workpieces), and a pick-up suction cup disposed above the support platform near the second end. The mechanism also includes a first driving member, a second driving member, and a first... The three-drive configuration allows for simultaneous activation of either the first and second drives, or the first and third drives. This ensures that after the workpiece at the second end is removed, the first and second drives activate simultaneously to temporarily store a portion of the tape within the space created by the moving shaft. Then, while the chuck continues to pick up material, the first and third drives activate simultaneously to wind the temporarily stored tape onto the take-up roll. This alternating control logic of "tape storage linked to unloading and moving shaft" and "tape release linked to take-up and moving shaft" enables continuous material picking without stopping the chuck, while avoiding tape tension fluctuations caused by frequent start-stop of the unloading and take-up drives, thus ensuring stable tape feeding and picking accuracy. By using tape to adhere to the film and the chuck to pick up the workpiece on the other side of the film, rapid and reliable separation of the workpiece from the film is achieved. This mechanism significantly improves material picking efficiency.

[0027] Please see Figures 1 to 8 This application provides a workpiece film separation mechanism, including: a fixing frame 1, a support platform 2, a feeding roll 31, a receiving roll 32, and a material handling component 4.

[0028] Two fixing brackets 1 extend along the first direction X. The two fixing brackets 1 are spaced apart along the second direction Y. The first direction X, the second direction Y, and the vertical direction Z are mutually perpendicular, and the first direction X and the second direction Y are two perpendicular directions in the horizontal plane.

[0029] like Figure 4 As shown, a movable shaft 11 extending along the second direction Y is provided between the two fixed frames 1. The movable shaft 11 is connected to a first driving member 12 for driving the movable shaft 11 to move along the first direction X. Figure 2 As shown, the support platform 2 is fixedly mounted above the fixing frame 1. The support platform 2 has a first end 21 and a second end 22 opposite each other in the first direction X.

[0030] like Figure 3As shown, the feed roll 31 and take-up roll 32 are positioned below the fixed frame 1. The tape 33 of the feed roll 31 enters the support platform 2 through the first end 21, then winds around the moving shaft 11 through the second end 22, and finally reaches the take-up roll 32. The upward-facing side of the tape 33 on the support platform 2 is adhesive, used to adhere to the film 10 with multiple workpieces 20. The lower surface of the film 10 is adhered to the tape 33, and the upper surface of the film 10 has multiple workpieces 20. The feed roll 31 is connected to a second drive member 34, used to drive the feed roll 31 to rotate around a first rotating axis extending in the second direction Y to feed the material. The take-up roll 32 is connected to a third drive member 35, used to drive the take-up roll 32 to rotate around a second rotating axis extending in the second direction Y to take the material. The first drive member 12, the second drive member 34, and the third drive member 35 are configured such that the first drive member 12 and the second drive member 34 are activated simultaneously, or the first drive member 12 and the third drive member 35 are activated simultaneously.

[0031] like Figure 8 As shown. The material handling assembly 4 includes a material handling suction cup 41 disposed above the support platform 2. The material handling suction cup 41 is disposed near the second end 22 and is used to remove the workpiece 20 from the second end 22. After the material handling suction cup 41 removes the workpiece 20, the empty film 10 moves together with the tape 33 to the take-up roll 32.

[0032] The workpiece film separation mechanism provided in this embodiment comprises two fixed frames 1 extending along the first direction X and spaced apart in the second direction Y, and a movable shaft 11 extending along the second direction Y between them (connected to a first driving member 12 to drive it to move along the first direction X), a support platform 2 (having a first end 21 and a second end 22 opposite to each other) fixedly disposed above the fixed frames 1, a feed roll 31 and a take-up roll 32 disposed below the fixed frames 1 (the tape 33 of the feed roll 31 enters the support platform 2 through the first end 21, then winds around the movable shaft 11 through the second end 22, and finally reaches the take-up roll 32, with the tape 33 on the support platform 2 having its adhesive side facing upward to stick to the film 10 with multiple workpieces 20), and a picking suction cup 41 disposed above the support platform 2 near the second end 22, and the first driving member 12 and the second driving member 34 are connected to the support platform 2. The first drive unit 12 and the second drive unit 34 are configured to start simultaneously, or the first drive unit 12 and the third drive unit 35 are configured to start simultaneously. This allows the first drive unit 12 and the second drive unit 34 to start simultaneously after the workpiece 20 at the second end 22 is removed, temporarily storing part of the tape 33 in the space formed by the movement of the moving shaft 11. Then, while the picking suction cup 41 continues to pick up the material, the first drive unit 12 and the third drive unit 35 start simultaneously to roll the temporarily stored tape 33 onto the take-up roll 32. Through the alternating control logic of "releasing the tape 33 in conjunction with the moving shaft 11" and "releasing the tape 33 in conjunction with the take-up roll 11", the picking suction cup 41 can pick up the material continuously without stopping. At the same time, it avoids the tension fluctuation of the tape 33 caused by frequent start and stop of the picking and unloading drive units, ensuring the smoothness of the tape 33 feeding and the picking accuracy. By using adhesive tape 33 to hold the film 10 in place, and using a suction cup 41 to pick up the workpiece 20 on the other side of the film 10, the workpiece 20 can be quickly and reliably separated from the film 10. This mechanism can significantly improve material handling efficiency.

[0033] In this embodiment, when the first driving member 12 and the second driving member 34 are activated simultaneously, the second driving member 34 drives the unloading roll 31 to unload the material, and the first driving member 12 drives the moving shaft 11 to move away from the second end 22. By limiting the specific actions when the first driving member 12 and the second driving member 34 are activated simultaneously, after the picking suction cup 41 takes away the workpiece 20 from the second end 22, the moving shaft 11 moves away from the second end 22, temporarily storing the tape 33 with the film 10 attached in the space formed by the movement of the moving shaft 11. This achieves the linkage between unloading and the moving shaft 11, avoiding the tape 33 from accumulating too much or becoming loose during the picking process, and providing a stable tape 33 buffer for subsequent material collection.

[0034] Specifically, when the first drive unit 12 and the third drive unit 35 are activated simultaneously, the third drive unit 35 drives the take-up roll 32 to release the material, and the first drive unit 12 drives the moving shaft 11 to move towards the second end 22. By limiting the specific actions of the first drive unit 12 and the third drive unit 35 when they are activated simultaneously, while the material-picking suction cup 41 continues to pick up the material, the moving shaft 11 moves towards the second end 22, gradually releasing the temporarily stored tape 33 and winding it onto the take-up roll 32. This achieves the linkage between the take-up and the moving shaft 11. The slow return of the moving shaft 11 smoothly winds up the temporarily stored tape 33, avoiding sudden tension changes or wrinkles in the tape 33 caused by the take-up roll 32 directly pulling the temporarily stored tape 33, thus ensuring the smoothness of the take-up process.

[0035] In this application, at any given time, only one of the second drive member 34 and the third drive member 35 is in operation, while the first drive member 12 remains continuously open. The direction of rotation when the first drive member 12 and the second drive member 34 are engaged is opposite to the direction of rotation when engaged with the third drive member 35, thereby realizing the forward and reverse movement of the moving shaft 11 in the first direction X. The material handling assembly 4 can operate continuously without stopping.

[0036] like Figure 8 As shown, the material handling assembly 4 also includes a first slide rail 42, a first mounting plate 45, a second slide rail 43, and a second mounting plate 46. The first slide rail 42 extends along a first direction X. The first mounting plate 45 is slidably connected to the first slide rail 42. The second slide rail 43 extends along a vertical direction Z and is fixedly mounted on the first mounting plate 45. The second mounting plate 46 is slidably connected to the second slide rail 43. The second mounting plate 46 is fixedly connected to a plurality of material handling suction cups 41 spaced apart in a second direction Y. This forms a composite motion structure of "horizontal sliding + vertical sliding". The material handling suction cups 41 move horizontally above the workpiece 20 via the first slide rail 42 and descend vertically in the Z direction via the second slide rail 43 to pick up the workpiece 20. The two directions are independently controlled and do not interfere with each other, ensuring the accuracy and flexibility of the material handling action. At the same time, multiple material handling suction cups 41 can pick up multiple workpieces 20 simultaneously, improving the material handling efficiency.

[0037] Specifically, the first slide rail 42 is located on one side of the support platform 2 in the second direction Y, and is positioned close to the second end 22. The second slide rail 43 is located above the support platform 2. Therefore, the material-grabbing suction cup 41 can pick up materials above the second end 22, achieving the shortest path and highest efficiency. The first mounting plate 45 is connected to a fourth driving member 47, which drives the first mounting plate 45 to move along the first direction X. The second mounting plate 46 is connected to a fifth driving member 48, which drives the second mounting plate 46 to move along the vertical direction Z. The independent configuration of the fourth driving member 47 and the fifth driving member 48 ensures the controllable movement accuracy and speed of the material-grabbing suction cup 41 in both directions, further improving the reliability and cycle time of the material-grabbing action.

[0038] Furthermore, the second mounting plate 46 is provided with a third slide rail 44 extending along the second direction Y, and multiple material-picking suction cups 41 are slidably connected to the third slide rail 44. The material-picking suction cups 41 are connected to a sixth driving member 49, which is used to drive the material-picking suction cups 41 to move along the second direction Y. Thus, the spacing between the multiple material-picking suction cups 41 can be flexibly adjusted in the second direction Y to adapt to different arrangement spacings of workpieces 20 on films 10 of different sizes. The material-picking suction cup 41 assembly can be adapted to the material-picking needs of various specifications of products without changing them, which significantly improves the versatility and changeover efficiency of the equipment.

[0039] like Figure 5 As shown, a synchronous belt 13 is provided on the inner side of the fixed frame 1. The end of the synchronous belt 13 away from the second end 22 is connected to a drive shaft 14, which is connected to a first drive member 12. The first drive member 12 is used to drive the drive shaft 14 to rotate around a third rotation axis extending in the second direction Y, thereby driving the synchronous belt 13 to move in the first direction X. The two ends of the moving shaft 11 along the second direction Y are respectively fixedly connected to the two synchronous belts 13. Thus, the two sides of the moving shaft 11 are mechanically linked through the first drive member 12 and the two synchronous belts 13, ensuring that the two ends of the moving shaft 11 are completely synchronized when moving in the first direction X, avoiding the skew or jamming of the moving shaft 11 due to asynchrony. At the same time, the synchronous belt 13 transmission method has a simple structure and smooth transmission, which is conducive to the precise control of the position of the moving shaft 11 during the temporary storage and release of the tape 33.

[0040] Preferably, such as Figure 6 As shown, the support platform 2 is provided with a heating component 23 near the second end 22, which is used to heat the film 10 and the workpiece 20. This allows the film 10 and the workpiece 20, which are stuck on the tape 33, to pass through the area of ​​the heating component 23 before being picked up. This can weaken the adhesion between the film 10 and the workpiece 20, making it easier for the pick-up suction cup 41 to remove the workpiece 20 from the film 10 and improving the success rate of picking up the workpiece.

[0041] like Figure 7 As shown, the second end 22 is provided with a separation block 24, and the upper surface of the separation block 24 is provided with a recessed step 25, with the higher side of the recessed step 25 located at the second end 22. The side of the separation block 24 is a slope 26, which gradually moves away from the second end 22 from top to bottom, so that when the tape 33 passes through the second end 22, it makes a turn at the separation block 24. The higher side of the recessed step 25 causes the tape 33 to be slightly lifted at the recessed step 25. Combined with the guiding effect of the slope 26, it helps the workpiece 20 and the film 10 on the tape 33 to achieve pre-separation at the second end 22, creating favorable conditions for the suction cup 41 to pick up the material, and further improving the success rate of picking up the material.

[0042] In this embodiment, the unwind roll 31 is positioned near the first end 21, and the rewind roll 32 is positioned near the second end 22. The centers of the unwind roll 31 and the rewind roll 32 are located in the same horizontal plane. A first tensioning shaft 27 is fixedly provided on the side of the first end 21 away from the support platform 2 in the first direction X. A second tensioning shaft 28 is fixedly provided below the separating block 24 on the side of the first direction X near the support platform 2. This forms a complete tape 33 path tensioning system. The first tensioning shaft 27 and the second tensioning shaft 28 tension the tape 33 from both vertical and horizontal directions, ensuring the flatness and tension stability of the tape 33 throughout the entire process of unwinding, passing through the support platform 2, winding around the moving shaft 11, and rewinding. The tape 33 between the second tensioning shaft 28 and the moving shaft 11 is horizontally positioned, and the second tensioning shaft 28 is located on the side of the moving shaft 11 closer to the second end 22. This makes the path change of the tape 33 between the moving shaft 11 and the second tensioning shaft 28 smoother when the moving shaft 11 moves along the first direction X, further optimizing the effect of temporary storage and release of the tape 33.

[0043] Furthermore, such as Figure 3 As shown, a third tensioning shaft 29 is located below the second tensioning shaft 28 and away from the second end 22. The third tensioning shaft 29 is situated between the moving shaft 11 and the take-up roll 32. The conveyor belt 33 is horizontally positioned between the third tensioning shaft 29 and the moving shaft 11. To ensure smoother movement of the conveyor belt 33, other tensioning shafts can be installed at predetermined positions as needed, between the unloading roll 31 and the first tensioning shaft 27, and between the third tensioning shaft 29 and the take-up roll 32. Figure 6 As shown, the middle of the support platform 2 can be hollowed out to reduce friction with the tape 33.
