Detailed Implementation

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0053] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0054] Example 1: The specific structure of this utility model is as follows:

[0055] Please refer to the appendix. Figure 1-8 The present invention provides a membrane peeling mechanism, comprising a support frame 300, a Z-axis drive mechanism 100, a first clamping mechanism 200, a Y-axis sliding mechanism 400, a second clamping mechanism 500, and a tension mechanism 600.

[0056] like Figure 5 As shown, the support frame 300 has a peeling platform, which is provided with an adsorption structure and a Y-axis clearance space; the support frame 300 includes a first upright plate 10, a second upright plate 8 and a U-shaped bracket 11, and the first upright plate 10 and the second upright plate 8 are connected horizontally at the top through the U-shaped bracket 11 after being erected.

[0057] The upper surface of the U-shaped support 11 has adsorption holes, and its interior has a negative pressure channel communicating with the adsorption holes. A negative pressure connector 34 is connected to the side of the U-shaped support 11, and the negative pressure connector 34 is connected to the negative pressure channel. After the membrane material is sent to the peeling platform, it is adsorbed through the adsorption holes. At this time, the membrane material needs to be tensioned for peeling.

[0058] like Figure 3 As shown, the Z-axis drive mechanism 100 is mounted on the support frame 300. The Z-axis drive mechanism 100 has a Z-axis power source and a Z-axis movable part that is driven and connected to the Z-axis power source. After being driven, the Z-axis movable part performs a Z-axis lifting and lowering action. The Z-axis power source of the Z-axis drive mechanism 100 is a linear motor 28, and a motor seat 18 is provided on the housing of the linear motor 28.

[0059] The linear motor 28 has a lead screw connected to the upward-facing drive shaft, and the lead screw is threadedly connected to the Z-axis movable part;

[0060] The Z-axis movable part includes a lifting block 19, which is slidably connected to the Z-axis guide rail 25 via a first slider 26. The Z-axis guide rail 25 is mounted on a third vertical plate 17, and the third vertical plate 17 is fixed to the support frame 300.

[0061] The Z-axis drive mechanism 100 further includes:

[0062] The sensing plate 20 is fixed to the lifting block 19 on the side;

[0063] A photoelectric sensor 29 is disposed on the upright plate 17 and adjacent to the Z-axis guide rail 25. The photoelectric sensor 29 has a slot through which the moving path of the sensing element 20 can pass. The photoelectric sensor 29 has multiple positions for sensing the position of the sensing element 20, and thus the position of the lifting block 19.

[0064] The operation process of the Z-axis drive mechanism 100 is as follows: the linear motor 28 drives the lead screw to rotate, the rotation of the lead screw drives the lifting block 19 to rise and fall, and the lifting block 19 drives the entire first clamping mechanism 200 to rise and fall synchronously.

[0065] like Figure 4 As shown, the first clamping mechanism 200 is installed on the Z-axis movable part. The first clamping mechanism 200 has a first clamping power source and a first clamping part that is driven and connected to the first clamping power source. After the first clamping part is driven, it performs an opening and closing action in the Z-axis direction, and its first clamping jaw faces the upper region of the support frame 300.

[0066] The first clamping power source is a first pneumatic slide 30, which is connected to the Z-axis movable part through a first cylinder seat 21;

[0067] The first clamping part includes a first upper clamping plate 24 and a first lower clamping plate 22 arranged vertically. The driving end of the first pneumatic slide 30 is connected to the first upper clamping plate 24 and controls the lifting and lowering of the first upper clamping plate 24.

[0068] The first lower clamping plate 22 is fixed to the upper end of the first cylinder seat 21 and is located directly below the first upper clamping plate 24. The first clamping opening is formed between the first upper clamping plate 24 and the first lower clamping plate 22. The opposing clamping surfaces of the first upper clamping plate 24 and the first lower clamping plate 22 are provided with concave and convex textures. The function of the concave and convex textures is to increase the friction and clamp the membrane material more tightly.

[0069] The operation of the first clamping mechanism 200 is as follows: When the lifting block 19 reaches the position of the upper photoelectric sensor 29, the sensing plate 20 is in the slot of the upper photoelectric sensor 29. The sensing plate 20 sends a position signal to the processor, and the processor controls the linear motor 28 to stop working. Initially, the first pneumatic slide 30 drives the first upper clamping plate 24 to rise, so that the first clamping jaws of the first upper clamping plate 24 and the first lower clamping plate 22 are in an open state. When the first clamping mechanism 200 arrives at the position of the upper photoelectric sensor 29 in sync with the lifting block 19, the film material is fed into the peeling platform by the external feeding device and one end of the film material is in the first clamping jaw area. The first pneumatic slide 30 drives the first upper clamping plate 24 to descend, and the first clamping jaw closes to clamp one end of the film material.

[0070] like Figure 6 As shown, the Y-axis sliding mechanism 400 is mounted on the support frame 300 and located below the peeling platform, and has a Y-axis movable part capable of moving along the Y-axis. The Y-axis sliding mechanism 400 includes:

[0071] Base plate 1;

[0072] A Y-axis linear guide rail 32 is set on the upper surface of the base plate 1 along the Y-axis. The movable part of the Y-axis is a sliding plate 2, which is slidably connected to the Y-axis linear guide rail 32 via a second slider 31.

[0073] The limiting block 7 is fixed to the base plate 1 and is used to limit the second clamping mechanism 500.

[0074] like Figure 7 As shown, the second clamping mechanism 500 is installed on the Y-axis movable part and moves within the Y-axis clearance space. The second clamping mechanism 500 has the same structure as the first clamping mechanism 200. It has a second clamping power source and a second clamping part that is driven and connected to the second clamping power source. After the second clamping part is driven, it performs an opening and closing action in the Z-axis direction, and its second clamping jaw faces the upper region of the support frame 300.

[0075] The second clamping power source is a second pneumatic slide 36, which is connected to the Y-axis movable part through a second cylinder seat 3;

[0076] The second clamping part includes a second upper clamping plate 6 and a second lower clamping plate 4 arranged vertically. The driving end of the second pneumatic slide 36 is connected to the second upper clamping plate 6 and controls the lifting and lowering of the second upper clamping plate 6.

[0077] The second lower clamping plate 4 is fixed to the upper end of the second cylinder seat 3 and is located directly below the second upper clamping plate 6, and the second clamping opening is formed between the second upper clamping plate 6 and the second lower clamping plate 4.

[0078] like Figure 8 As shown, the tension mechanism 600 is installed on the support frame 300, and after being connected with the second clamping mechanism 500, it forms a force-bearing structure in which the second clamping mechanism 500 moves away from the first clamping mechanism 200.

[0079] The tension mechanism 600 includes:

[0080] A fixing block 13 is fixed to the support frame 300 on the side. The fixing block 13 has a through hole and locking holes on both sides of the through hole.

[0081] The guide rod 14 has two rods, and the upper ends of the two guide rods 14 are respectively fixed with two lock holes;

[0082] The gravity hammer 15 has two through holes on the top and bottom, and the two through holes are fitted one-to-one onto the two guide rods 14.

[0083] A roller assembly having a fixed shaft 12 and rollers 33 rotatably connected to the fixed shaft 12, the fixed shaft 12 being fixed to the support frame 300;

[0084] One end of the pull rope 35 is connected and fixed to the Y-axis movable part, and the other end passes around the roller 33 and is connected and fixed to the gravity hammer 15.

[0085] Tension mechanism 600 provides tension. When the membrane material is clamped by first clamping mechanism 200 and second clamping mechanism 500, the pull rope is tightened by the gravity of gravity hammer 15. The pull rope is connected to second clamping mechanism 500, which slides on Y-axis linear guide rail 32. The pull rope is pulled by gravity hammer 15, thereby causing second clamping mechanism 500 to tighten the membrane material and make the membrane material taut.

[0086] Taking membrane material feeding as an example, the membrane material peeling mechanism of this utility model is installed on the Y / O axis of the feeding platform, and in conjunction with the picking robot mechanism on the X / Z axis, after the material picking CCD is aligned, the feeding platform moves the membrane material to the center of the suction head of the picking robot mechanism, and then the suction head picks up the membrane material, thereby achieving efficient and highly stable feeding of the membrane material.

[0087] In summary, the membrane peeling mechanism of this invention has a simple structure, with all components working in concert to efficiently peel and feed the membrane. The Z-axis drive mechanism drives the first clamping mechanism to reciprocate in the Z-direction, clamping the membrane material, which is then vacuum-adsorbed onto the peeling platform for peeling. Simultaneously, the second clamping mechanism is fixed to the Y-axis sliding mechanism and connected to the tension mechanism via a pull rope. The second clamping mechanism clamps the membrane material and provides it with a certain tension, ensuring a stable and reliable process. This membrane peeling mechanism is applicable to a wide variety of membrane types, meeting the needs of various production scenarios for feeding multiple membrane materials. By adjusting the clamping force of each clamping mechanism and the tension of the tension mechanism, it can adapt to membrane materials of different thicknesses and materials, greatly improving the mechanism's versatility. It significantly improves the feeding cycle time and yield of the membrane material, thereby increasing production efficiency. The precise drive mechanism and stable clamping and tension structure prevent wrinkles and damage during peeling and feeding, ensuring membrane quality, while the rapid operating cycle meets the requirements of high-speed production.

Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
