[0001] The utility model relates to the technical field of aluminum foil production, in particular to a foil picking device. Background Art

[0002] During the electrochemical etching production process of capacitor aluminum foil, due to factors such as equipment, there are occasional phenomena of local damage on continuous aluminum foil. The fallen foils adhere to the inner wall of the etching tank or float on the surface of the liquid inside the etching tank, which has a great impact on subsequent production. In the prior art, in order to pick up the foils, it is necessary to go through steps such as shutting down the machine, discharging the tank liquid, disassembling the electrode, manually picking up in the tank, installing the electrode, preparing the tank liquid, and starting the machine.

When the lifting mechanism operates, it can drive the clamping mechanism to take the connection point between the clamping mechanism and the bottom plate as a fulcrum, change the posture of the clamping mechanism, and make the clamping mechanism cooperate with the bottom plate to pick up broken foils.

[0004] Although the above clamping device has a better effect on picking up the foils floating on the surface of the liquid inside the etching tank, the picking efficiency for the foils adhering to the inner wall of the etching tank is not good. Summary of the Utility Model

[0047] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0048] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0049] To solve the problem of poor picking efficiency of the foil attached to the inner wall of the etching tank in the prior art. The embodiments of the present invention provide a foil picking device, including: an upper clamp body 1, a lower clamp body 2, an elastic airbag 4, a pressing rod 5, a lifting assembly and other parts.

[0050] Among them, the upper clamp body 1 is hinged to the lower clamp body 2. Taking the hinge as the demarcation line, the part located at the left end of the hinge is defined as the front end, and the part located at the right end of the hinge is defined as the rear end. The fitting part between the upper clamp body 1 and the lower clamp body 2, that is, the front end of the upper clamp body 1 and the lower clamp body 2, is the clamping part, and the clamping part is mainly used for clamping the foil. The pressing rod 5 is movably arranged at the lower end of the upper clamp body 1 and can move up and down under the drive of the upper clamp body 1. The lifting assembly is arranged at the rear end of the lower clamp body 2 and is hinged to the rear end of the upper clamp body 1 at the same time. The action of the lifting assembly can drive the upper clamp body 1 to take the hinge point between the upper clamp body 1 and the lower clamp body 2 as the fulcrum, and use the lever principle to change the posture of the upper clamp body 1, that is, if the front end of the upper clamp body 1 moves away from the lower clamp body 2, the rear end will move closer to the lower clamp body 2, and if the front end of the upper clamp body 1 moves closer to the lower clamp body 2, the rear end will move away from the lower clamp body 2; through the cooperation between the lower clamp body 2 and the upper clamp body 1, the picking operation of the foil is realized.

[0051] An elastic airbag 4 is arranged at a position adjacent to the lifting assembly at the rear end of the lower clamp body 2. The upper side of the elastic airbag 4 is connected to the lower end of the pressing rod 5. When the pressing rod 5 moves, the elastic airbag 4 deforms. An opening is formed at the lower end of the elastic airbag 4, and the opening is communicated with an air passage 25 opened inside the lower clamp body 2, so that the elastic airbag 4 can exhaust or inhale air through the air passage 25. When the lifting assembly acts on the upper clamp body 1, the elastic airbag 4 contracts or expands under the action of the pressing rod 5. While contracting or expanding, the elastic airbag 4 deflates or inhales air from the foil through the air passage 25 inside the lower clamp body 2; by deflating, the foil attached to the surface of the object is separated from the surface of the object, and then a certain suction force is provided to the foil by inhaling air. The suction force plays a certain role in adsorbing and fixing the foil. By the mutual cooperation of the elastic airbag 4 and the clamping part, the efficient picking of the foil separated from the surface of the object can be effectively realized.

[0052] Specifically, as Figure 1 shown, the lower clamp body 2 is in the shape of a rectangular plate, and the dimension in the length direction is much larger than the dimension in the width direction. Preferably, in this embodiment, the length of the lower clamp body 2 is about 0.25 m. In order to facilitate the lower clamp body 2 to shovel the foil, as Figure 1 shown, the width direction of the front end of the lower clamp body 2 is processed into a slope structure, that is, the thickness at the front edge of the lower clamp body 2 gradually increases from 0 to the thickness of the rest of the lower clamp body 2, forming a shoveling slope 21. An air passage 25 running along the length direction of the lower clamp body 2 and extending towards the front end of the lower clamp body 2 is penetrated inside the lower clamp body 2. In order to prevent liquid from entering the air passage 25, a PTFE film (not shown in the figure) is hermetically covered at the air inlet (air outlet) of the air passage 25, that is, at the front end of the lower clamp body 2, so as to achieve the effect that gas passes through the air passage 25 while liquid does not pass through the air passage 25.

[0053] As Figure 1 , 3 , as shown in Figure 4, the inside of the upper clamping body 1 is a hollow structure, including a fitting portion 11 and a separating portion 12 which are integrally formed. Among them, the fitting portion 11 can be fitted with the front end of the lower clamping body 2, and the shape and size of the fitting portion 11 are adapted to the corresponding part of the lower clamping body 2, so that the picking device can conveniently clamp the foil. A first notch 123 and a second notch 124 adjacent to the first notch 123 are formed at the lower end of the separating portion 12 along the length direction of the separating portion 12. The upper end of the first upper connecting plate 121 is movably arranged in the first notch 123, and the upper end of the pressing rod 5 is movably arranged in the second notch 124. The lengths of the first notch 123 and the second notch 124 are strictly calculated. When the upper clamping body 1 rotates upward or downward relative to the lower clamping body 2, it can ensure that the first upper connecting plate 121 can rotate around the hinge point at its lower end, and at the same time, the pressing rod 5 only moves up and down within a limited vertical path. That is to say, the lengths of the first notch 123 and the second notch 124 can respectively provide a certain sliding space for the upper end of the first upper connecting plate 121 and the upper end of the pressing rod 5, so that the picking device will not malfunction due to mechanical interference between components. In other implementation scenarios, a sliding sleeve can be respectively arranged at the upper end of the first upper connecting plate 121 and the upper end of the pressing rod 5. Through their respective sliding sleeves, the first upper connecting plate 121 and the pressing rod 5 are indirectly slidably sleeved on the separating portion 12.

[0054] A second upper connecting plate 122 is fixedly arranged at the rear end position of the separating portion 12, and the second upper connecting plate 122 is hinged to the lifting assembly through a second pivot shaft 34. Corresponding to the first upper connecting plate 121, a lower connecting plate 22 is also arranged on the lower clamping body 2, and the first upper connecting plate 121 is hinged to the lower connecting plate 22 through a first pivot shaft 24.

[0055] As Figure 1 , 3 shown, the aforementioned lifting assembly includes: a connecting rod 31, a movable tube 32, and a connecting block 33. Among them, the length of the connecting rod 31 is about 3m, and it is fixedly arranged at the rear end of the lower clamping body 2 adjacent to the rear end. The connecting rod 31 can be vertically arranged on the rear end of the lower clamping body 2, or can be arranged in a manner of inclining at a certain angle relative to the rear end of the lower clamping body 2. The movable tube 32 is installed on the connecting rod 31 and can slide along the length direction of the connecting rod 31. The length of the movable tube 32 is less than the length of the connecting rod 31. A connecting block 33 is fixedly arranged at one end of the movable tube 32 adjacent to the upper clamping body 1. The second pivot shaft 34 sequentially passes through the second upper connecting plate 122 and the connecting block 33 to realize the hinging of the upper clamping body 1 and the movable tube 32. Pull the movable tube 32, the connecting block 33 drives the second upper connecting plate 122 to move, and the front end of the upper clamping body 1 moves in the opposite direction relative to the second upper connecting plate 122.

[0056] AsFigures 2 - 5 As shown, in this embodiment, the elastic airbag 4 is disposed in the accommodation chamber 23 at the rear end of the lower clamp body 2. An opening is formed at the lower end thereof, and the opening is communicated with the air passage 25 penetrating through the inside of the lower clamp body 2. In this embodiment, the air passage 25 can be in the shape of "[" or "7".

[0057] As Figure 3 As shown in or 4, a pressure rod 5 is disposed above the elastic airbag 4. The pressure rod 5 is generally in the shape of "I". It includes a horizontally disposed part 51 and a vertically disposed part 52 integrally formed. Among them, the horizontally disposed part 51 is a plate-shaped pressing plate, which is located in the accommodation chamber 23 and abuts against the top of the elastic airbag 4. The size of the horizontally disposed part 51 is adapted to the accommodation chamber 23 and can move up and down in the accommodation chamber 23. The vertically disposed part 52 is generally in the shape of "T". One end thereof penetrates through the accommodation chamber 23 and is disposed in the accommodation chamber 23, and the other end penetrates through the second notch 124 and is located in the hollow part inside the upper clamp body 1. The vertically disposed part 52 and the second notch 124 are horizontally movable through notch cooperation; similarly, the vertically disposed part 52 can move up and down relative to the accommodation chamber 23.

[0058] During specific operation, first place the slope 21 of the lower clamp body 2 near the foil. Then move the movable tube 32 downward. The movable tube 32 drives the rear end of the upper clamp body 1 to move downward synchronously. The downward moving rear end of the upper clamp body 1 simultaneously drives the front end of the upper clamp body 1 to move upward and the pressure rod 5 to move downward; during the upward movement of the front end of the upper clamp body 1, it gradually separates from the front end of the lower clamp body 2, and the clamping part is in an open state; when the pressure rod 5 moves downward, the elastic airbag 4 is compressed, and the gas therein is discharged through the air passage 25 and acts on the foil, causing the foil to separate from the object surface; at the same time, shovel the slope 21 of the lower clamp body 2 under the foil; then move the movable tube 32 upward. During the upward movement of the movable tube 32, the clamping part gradually closes and at the same time the elastic airbag 4 performs an inhalation action under its own elastic force, generating a suction force on the foil, causing the foil to be adsorbed and fixed on the surface of the lower clamp body 2. As the clamping part gradually closes, the picking operation of the foil is completed; the efficient picking of the foil is realized through the cooperation of the clamping part and the elastic airbag 4.

[0059] In order to further improve the clamping force of the clamping part, a torsion spring 6 is also disposed at the hinged position between the upper clamp body 1 and the lower clamp body 2. The torsion spring 6 realizes the function of further clamping the front clamping part by pushing the rear end of the upper clamp body 1 upward and the front end of the upper clamp body 1 downward.

[0060] Furthermore, in order to facilitate pulling the movable tube 32, as Figure 1 As shown in or 2, a handle 321 is disposed at one end of the movable tube 32 away from the lower clamp body 2. Similarly, a limit ball 311 is disposed at one end of the connecting rod 31 away from the lower clamp body 2.

[0061] Further, in order to reduce the resistance when the movable tube 32 moves, the inner diameter of the movable tube 32 is slightly larger than the outer diameter of the connecting rod 31, such as 1 to 5 mm larger.

[0062] Further, in order to improve the service life of the picking device, a corrosion layer for preventing electrochemical corrosion is wrapped on the outer sides of the upper clamp body 1, the lower clamp body 2, the pressure rod 5 and the lifting assembly.

[0063] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
