Description

Technical Field

[0001] The invention relates to the technical field of plastic connection, and in particular to a conductive foam connection device. Background Art

[0002] Foam is a special plastic, which is made of plastic particles. Foam can be divided into PU foam, anti-static foam, conductive foam, aluminum foil foam, CR foam, etc. Among them, conductive foam is widely used in electronic products such as PDP TV, LCD monitor, LCD TV, mobile phone, notebook computer, MP3, communication cabinet, medical equipment, as well as military and aerospace fields. Plastic film is a plastic film, which can be made of PET, BOPP, PVC, PP, PE and other materials.

[0003] A plastic product purchased by a customer from our company requires two types of conductive foams to be connected to the surface of a plastic film. These two types of conductive foams are arranged in multiples along the length direction of the plastic film, one to one, and the corresponding conductive foams are very close. Among them, the length direction of the first type of conductive foam corresponds to the length direction of the plastic film; the length direction of the second type of conductive foam corresponds to the width direction of the plastic film, and it needs to be flattened when connected. Based on comprehensive consideration of product requirements, production efficiency, material saving, production line length and other factors, our company's technical personnel designed a production process of multiple connections:

[0004] One-time connection: unwind the plastic film, connect the first conductive foam one by one to the surface of the plastic film by pasting, and then rewind the plastic film.

[0005] Secondary connection: unwind the rewound plastic film again, and stick the second conductive foam on the surface of the plastic film one by one; and punch the second conductive foam stuck on the surface of the plastic film to flatten it; in this way, the connection of the second conductive foam can be completed.

[0006] During the secondary connection, since the first conductive foam and the second conductive foam are very close to each other, before punching the second conductive foam, the plastic film needs to be positioned with the help of the positioning holes on the plastic film to ensure accurate punching of the second conductive foam and avoid punching of the first conductive foam. However, the existing conductive foam connection device often keeps the plastic film in a taut state; in this case, the plastic film cannot be positioned because it is difficult to fine-tune the position.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] like Figure 1 to Figure 6As shown, an embodiment of the present invention provides a conductive foam connection device. The conductive foam connection device includes: a pasting mechanism 1 for pasting the conductive foam on the plastic film, a stamping mechanism 2 arranged on the right side of the pasting mechanism 1 and stamping the conductive foam pasted on the plastic film, and a conveying mechanism 3 arranged on the right side of the stamping mechanism 2 and driving the plastic film to move to the right. Among them, the stamping mechanism 2 includes: a stamping table 4, a first lifting seat 5 located above the stamping table 4, a first power source 6 for driving the first lifting seat 5 to move up and down, a die 7 installed at the bottom of the first lifting seat 5, and a first positioning rod 8. It should be understood that from the perspective of saving costs and speeding up the stamping frequency, the first power source 6 is preferably a linear cylinder; of course, according to the actual needs, it can also be changed to other driving devices such as electric push rods and oil cylinders. In order to make full use of the space, the first power source 6 is usually set below the punching table 4; the first lifting seat 5 can be fixedly connected to the first lifting frame below the punching table 4 through the first column, and the first power source 6 can drive the first lifting frame to move up and down, thereby driving the first lifting seat 5 to move up and down; a first guide through hole for the first column to pass through can be set on the punching table 4. In addition, in order to facilitate the first positioning rod 8 to be inserted into the positioning hole of the plastic film, the lower end of the first positioning rod 8 can be set to a spherical crown or a hemispherical shape. The conveying mechanism 3 includes: a roller 9 that supports the plastic film, a third power source 10 that drives the roller 9 to rotate, a pressure wheel 11 located above the roller 9, and a lifting unit that drives the pressure wheel 11 to swing up and down. It should be understood that the third power source 10 can be set as a servo motor or a stepping motor. When the first positioning rod 8 moves downward with the first lifting seat 5 to position the plastic film, the lifting unit lifts the pressure wheel 11 away from the roller 9. When the first positioning rod 8 moves upward with the first lifting seat 5 to be separated from the plastic film, the lifting unit lowers the pressing wheel 11 so that the pressing wheel 11 and the roller 9 can clamp the plastic film. It should be understood that when the pressing wheel 11 and the roller 9 can clamp the plastic film, the third power source 10 can drive the roller 9 to rotate, so that the plastic film can be moved to the right.

[0044] The specific implementation of the present invention is described below: the conveying mechanism 3 is made to move rightward with the plastic film in a stepping manner, so that the plastic film passes through the pasting mechanism 1 and the punching mechanism 2 in sequence. When the plastic film stops moving; for the part of the plastic film located at the pasting mechanism 1, the pasting mechanism 1 will initially paste the conductive foam on the part of the plastic film; for the part of the plastic film located at the punching mechanism 2, the punching mechanism 2 will punch the corresponding conductive foam of the part of the plastic film to flatten the corresponding conductive foam, thereby completing the connection between the conductive foam and the plastic film. Among them, before the die 7 of the punching mechanism 2 punches the conductive foam, the first positioning rod 8 of the punching mechanism 2 will be inserted into the positioning hole of the plastic film in advance to accurately position the part of the plastic film located at the punching mechanism 2, thereby ensuring accurate punching of the conductive foam. When the first positioning rod 8 is about to be inserted into the positioning hole of the plastic film, the lifting and placing unit will lift the pressing wheel 11 upward to make the pressing wheel 11 loosen the plastic film, so that the position of the plastic film can be fine-tuned with the insertion of the first positioning rod 8, thereby completing the accurate positioning of the plastic film. When the first positioning rod 8 moves upward to the positioning hole that is out of the plastic film, the lifting and placing unit will lower the pressing wheel 11, and the pressing wheel 11 will cooperate with the roller 9 to clamp the plastic film; at this time, the third power source 10 drives the roller 9 to rotate, and the plastic film can be moved to the right to be sent downstream for subsequent processing operations. In addition, the present invention can also be used for connecting other foam and film materials.

[0045] Example 2

[0046] like Figure 1 to Figure 5 As shown, on the basis of Example 1, the roller 9 is installed on the support platform 12, and the surface of the support platform 12 supports the plastic film; the lifting unit includes: a swing frame 13 whose right part is rotatably connected to the support platform 12, and a supporting member 14 for supporting the left part of the swing frame 13; the left part of the swing frame 13 is installed with an axle 15 extending in the front-to-back direction, and the pressure wheel 11 is installed on the axle 15; the middle part of the supporting member 14 is rotatably installed on the suspension 16; the left part of the swing frame 13 is connected to the supported member 17; when the first lifting seat 5 moves downward to drive the left part of the supporting member 14 to rotate downward, the right part of the supporting member 14 rotates upward and applies force to the supported member 17 to lift the left part of the swing frame 13 upward; when the first positioning rod 8 moves upward with the first lifting seat 5 to separate from the plastic film, the first lifting seat 5 releases the left part of the supporting member 14, and the left part of the swing frame 13 automatically falls with the pressure wheel 11, and drives the supporting member 14 to reset.

[0047] It should be understood that the table surface of the support 12 is roughly flush with the top of the roller 9; an opening can be set in the support 12 to allow the top of the roller 9 to be exposed and cooperate with the pressure wheel 11 to clamp the plastic film. The suspension 16 can be installed above the punching table 4 or the support 12, and there is a gap between the suspension 16 and the punching table 4 or the support 12 to allow the plastic film to pass through. The middle part of the supporting member 14 is rotatably connected to the suspension 16, and the rotating shaft points to the front and rear direction; when the first lifting seat 5 moves downward with the first positioning rod 8 and the die 7, the first lifting seat 5 will also press down the left part of the supporting member 14, so that the right part of the supporting member 14 rotates upward and applies force to the supported member 17 to lift the left part of the swing frame 13 upward; in this way, the wheel axle 15 installed on the left part of the swing frame 13 can lift the pressure wheel 11 upward away from the roller 9. The lifting and placing unit adopting the above-mentioned structure can better cooperate with the stamping mechanism 2 in synchronization, and the following actions are connected in sequence: as the first lifting seat 5 moves downward; first lift the pressure wheel 11 upward and away from the roller 9; then, the first positioning rod 8 is immediately inserted into the positioning hole of the plastic film, and the position of the plastic film is fine-tuned to position the plastic film; then, the die 7 cooperates with the stamping table 4 to accurately flatten the corresponding conductive foam; then, as the first lifting seat 5 moves upward, the die 7 is separated from the conductive foam, and the first positioning rod 8 is separated from the positioning hole of the plastic film; when the left part of the supporting member 14 is no longer subjected to the downward pressure applied by the first lifting seat 5, the pressure wheel 11 will fall back on the top of the roller 9 under the action of gravity, thereby cooperating with the roller 9 to clamp the plastic film; the third power source 10 drives the roller 9 to rotate, and the plastic film can continue to move to the right.

[0048] Example 3

[0049] like Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig.10 As shown, on the basis of Example 2, a pressing member 18 extending in the up-down direction is installed on the right side of the first lifting seat 5, and a first roller 19 is installed on the left part of the supporting member 14; the first lifting seat 5 applies force to the circumference of the first roller 19 through the lower part of the pressing member 18 to press the left part of the supporting member 14; the pressing member 18 includes: a main rod portion, a truncated cone portion, and a pressing portion connected in sequence from top to bottom; the diameter of the truncated cone portion gradually decreases from top to bottom, and the pressing portion is spherical or hemispherical; a second roller 20 is installed on the right part of the supporting member 14, and a force is applied to the entrusted member 17 through the circumference of the second roller 20 to lift the left part of the swing frame 13.

[0050] It should be understood that the top pressing member 18 can be installed on the right side of the first lifting seat 5 through the connecting member 55; specifically, the connecting member 55 includes: a connecting portion 56, two clamping portions 57 extending to the right from the connecting portion 56; the connecting portion 56 can be fixedly connected to the right side of the first lifting seat 5 through a fourth bolt; the two clamping portions 57 are provided with grooves on opposite sides to form a match with the main rod portion of the top pressing member 18; one of the clamping portions 57 is provided with a third threaded hole, and the other clamping portion 57 is provided with a light hole, so that the fifth bolt passes through the light hole and is screwed into the third threaded hole, so that the grooves of the two clamping portions 57 can clamp the main rod portion of the top pressing member 18; the fifth bolt is withdrawn from the third threaded hole, so that the main rod portion of the top pressing member 18 can be loosened, thereby adjusting the height of the top pressing member 18. In this way, the height of the top pressing member 18 is adjustable, and the lifting and lowering of the pressure wheel 11 can be controlled more flexibly. In addition, anti-slip grooves can be provided on the main rod portion of the top pressing member 18. In addition, whether the left part of the supporting member 14 is pressed down or the right part of the supporting member 14 is used to lift the receiving member 17 upward, there is a relative displacement in the left and right directions and the friction generated therefrom; the pressing part of the pressing member 18 applies force to the circumference of the first roller 19 to press down the left part of the supporting member 14; the circumference of the second roller 20 applies force to the receiving member 17 to lift the left part of the swing frame 13; the friction can be greatly reduced, thereby greatly reducing the wear. In addition, the strength of the mutual impact between the pressing member 18 and the supporting member 14 at the moment of contact can also be alleviated.

[0051] Example 4

[0052] like Figure 5 , Fig. 9 , Fig.10 As shown, on the basis of Example 2 or Example 3, the conveying mechanism 3 also includes: an anti-jump unit 21; the anti-jump unit 21 includes: a pressing piece 22 and a compression spring 23 that drives the pressing piece 22 to return downward; the pressing piece 22 is located at the top end of the left part of the swing frame 13 to transmit the downward pressure applied by the compression spring 23 to the left part of the swing frame 13.

[0053] It should be understood that if the pressure wheel 11 is purely dependent on gravity to fall back to the top of the roller 9, the pressure wheel 11 may easily rebound upward; in this case, the pressure wheel 11 cannot quickly and stably cooperate with the roller 9 to clamp the plastic film, which will cause the conveying mechanism 3 to be unable to stably and reliably convey the light plastic film to the right; especially in the case of high-frequency stamping of the stamping mechanism 2, the adverse effect on the stability of the conveying mechanism 3 is particularly obvious. By setting the anti-jump unit 21, the above situation can be avoided, ensuring the stability and reliability of the conveying mechanism 3.

[0054] Example 5

[0055] like Figures 9 to 11As shown, on the basis of Example 4, a third roller 24 is installed at the bottom of the pressing member 22; the top of the left part of the swing frame 13 has an arc-shaped notch that cooperates with the third roller 24; the anti-jump unit 21 also includes: a bracket 25, a guide rod 26 installed on the bracket 25; the bracket 25 includes: a vertical portion 27, a horizontal folding portion 28 located at the top of the vertical portion 27; the horizontal folding portion 28 is provided with a first threaded hole 29 running through from top to bottom; the guide rod 26 includes: a screw segment 30 that cooperates with the first threaded hole 29, and a guide segment 31 extending downward from the bottom end of the screw segment 30; the compression spring 23 is sleeved on the guide segment 31, the diameter of the screw segment 30 is larger than the diameter of the guide segment 31, the upper end of the compression spring 23 abuts against the lower end of the screw segment 30, and the lower end of the compression spring 23 abuts against the top of the pressing member 22; the top of the pressing member 22 has a guide hole 32 extending downward for the guide segment 31 of the guide rod 26 to be inserted.

[0056] It should be understood that by screwing the guide rod 26, the height of the guide rod 26 can be adjusted, thereby adjusting the bottom height of the screw section 30 of the guide rod 26; in this way, the degree to which the anti-jump unit 21 presses the left part of the swing frame 13 can be flexibly adjusted. When the left part of the swing frame 13 swings up and down, the left part of the swing frame 13 will also produce left and right displacement relative to the pressing member 22; the pressing member 22 applies pressure to the left part of the swing frame 13 through the third roller 24, which can greatly reduce the friction caused by this left and right displacement, thereby greatly reducing wear. In addition, an arc-shaped notch that cooperates with the third roller 24 is provided at the top of the left part of the swing frame 13, which can prevent the third roller 24 and the pressing member 22 from rotating around the guide rod 26 to a certain extent.

[0057] Example 6

[0058] like Fig. 9 As shown, on the basis of Example 5, the vertical portion 27 is provided with a strip hole 33 extending in the up-down direction; the pressing member 22 is connected to a limiting plate 34 on one side of the vertical portion 27 through a first bolt; the limiting plate 34 and the pressing member 22 are relatively restricted on both sides of the vertical portion 27, and the rod of the first bolt passes through the strip hole 33.

[0059] It should be understood that the above structure can prevent the pressing member 22 from rotating around the guide rod 26 and can prevent the pressing member 22 from shaking back and forth.

[0071] It should be understood that from the perspective of cost saving and frequency acceleration, the second power source 48 is preferably a linear cylinder; of course, according to the actual needs, it can also be changed to other driving devices such as electric push rods and oil cylinders. In order to make full use of space, the second power source 48 is usually set below the pasting table 46; the second lifting seat 47 can be fixed to the second lifting frame below the pasting table 46 through the second column, and the second power source 48 can drive the second lifting seat 47 to move up and down by driving the second lifting frame to move up and down; a second guide through hole for the second column to pass through can be set on the pasting table 46.

The pasting mechanism 1 may be provided with two unwinding rollers 53, one for unwinding the plastic film and the other for unwinding the conductive foam; the plastic film may be conveyed to the pasting table 46 from the bottom of the support plate 51 to the right, and the conductive foam may be conveyed to the pasting table 46 from the top of the support plate 51 to the right. The double-sided adhesive release paper peeled off from the lower surface of the conductive foam may bypass the right edge of the support plate 51 and be pulled to the left from the bottom of the support plate 51 to the rewinding roller 52. The rewinding roller 52 is made to rewind the double-sided adhesive release paper peeled off from the lower surface of the conductive foam, and the conductive foam may be conveyed to the right, and the double-sided adhesive release paper on the lower surface of the conductive foam may be peeled off with the help of the right edge of the support plate 51, thereby exposing the adhesive layer on the lower surface of the conductive foam. In this way, the second lifting seat 47 is moved downward with the cutter 49 to cut off the rightmost end of the conductive foam, and the cut conductive foam may be initially pasted on the upper surface of the plastic film with the help of the adhesive layer. The fourth power source 54 may be set as a servo motor or a stepping motor. The two unwinding rollers 53 can be set to rotate passively; or the two unwinding rollers 53 can be respectively adapted to servo motors or stepper motors, and the two unwinding rollers 53 can be set to rotate actively. The winding roller 52 and the unwinding roller 53 can be rotatably mounted on the roller frame through bearings.
