Description

Technical Field

[0001] The present invention relates to the technical field of fuel cell preparation, in particular to a splicing device. Background Art

[0002] A fuel cell is a chemical device that converts the chemical energy of a fuel directly into electrical energy. Also known as an electrochemical generator, the performance of the membrane electrode, a core component of a fuel cell, directly impacts the overall performance of the fuel cell.

[0003] The membrane electrode assembly consists of a CCM (catalyst coated membrane), a frame attached to each side of the CCM, and a gas diffusion layer. Carbon paper is often used to form the gas diffusion layer due to its excellent electrical conductivity and permeability. Carbon paper is typically supplied in roll form, and to facilitate automated production processes, consideration must be given to the issue of splicing the rolls.

[0004] Traditional methods of splicing tapes mainly involve manual tape application or staples, which not only results in low work efficiency, but also makes it difficult for manual tape application to meet subsequent requirements in the subsequent processing steps of carbon paper, including impregnation and heating. Staples will affect the accuracy of tape reeling and unwinding, which is not conducive to subsequent continuous automated production. Summary of the Invention

Compared to the manual tape application or stapler method in the prior art, this device has a high degree of automation and improves work efficiency. Furthermore, the pressing mechanism presses the first material tape, the adhesive tape, and the second material tape together, which, compared to manual tape application, provides high-quality glue application, minimizes impact on subsequent processes, and does not affect the tape reeling and unwinding accuracy as would be the case with staplers, thus facilitating subsequent continuous automated production.

[0054] See Figure 1 and Figure 2 One embodiment of the present application provides a splicing device 100 capable of automatically splicing a material strip. Specifically, the splicing device 100 can be used to splice carbon paper or carbon felt. Of course, in other embodiments, the type of material strip suitable for the splicing device 100 is not specifically limited.

[0055] The tape splicing device 100 includes a first tape splicing mechanism 10, a glue preparation mechanism 20, a second tape splicing mechanism 30, and a pressing mechanism. The first tape splicing mechanism 10 is used to fix the first material tape 200, the glue preparation mechanism 20 is used to place the adhesive tape 400 on the first material tape 200 fixed by the first tape splicing mechanism 10, and the second tape splicing mechanism 30 is used to place the second material tape 300 on the side of the adhesive tape 400 away from the first material tape 200. Figure 3 and Figure 4 The pressing mechanism includes a first pressing plate 41 and a second pressing plate 42. The first pressing plate 41 and the second pressing plate 42 can generate relative movement in the thickness direction of the first material strip 200, and respectively press the first material strip 200 and the second material strip 300 from both sides in the thickness direction to press the first material strip 200, the adhesive tape 400 and the second material strip 300, so that the first material strip 200 and the second material strip 300 are bonded and fixed by the adhesive tape 400.

[0056] It should be noted that, generally, the free end of the first material strip 200 is fixed to the first splicing mechanism 10, the adhesive preparation mechanism 20 places the adhesive tape 400 on the fixed portion of the first material strip 200 directly secured by the first splicing mechanism 10, and the free end of the second material strip 300 is placed on the adhesive tape 400. The first pressing plate 41 and the second pressing plate 42 respectively press the free ends of the first and second material strips 200, 300, so that the two are firmly bonded via the adhesive tape 400.

[0057] The tape splicing device 100 provided in the embodiment of the present application has a first tape splicing mechanism 10 that fixes the first material tape 200, a glue preparation mechanism 20 that automatically places the adhesive tape 400 on the first material tape 200, a second tape splicing mechanism 30 that automatically places the second material tape 300 on the adhesive tape 400, and a pressing mechanism that automatically presses the first material tape 200, the adhesive tape 400, and the second material tape 300 together, so that the first material tape 200 and the second material tape 300 are firmly bonded together by the adhesive tape 400. Compared with the manual application of the adhesive tape 400 or the stapler method in the prior art, the degree of automation is high, and work efficiency is improved. At the same time, the first material tape 200, the adhesive tape 400, and the second material tape 300 are pressed together by the pressing mechanism. Compared with the manual application of the adhesive tape 400, the adhesive tape 400 and the second material tape 300 are high in adhesive quality, have little impact on subsequent processes, and do not affect the accuracy of the material tape reeling and unwinding as the stapler method does, which is conducive to subsequent continuous automated production.

[0058] In some embodiments, see Figure 1 and Figure 2The tape splicing device 100 further includes a first mounting base 50 and a second mounting base 60. The first tape splicing mechanism 10 and the first pressing plate 41 are both mounted on the first mounting base 50, and the second tape splicing mechanism 30, the glue preparation mechanism 20, and the second pressing plate 42 are all mounted on the second mounting base 60. This allows each mechanism to be integrated on the first mounting base 50 and the second mounting base 60, resulting in a high degree of integration. Of course, in other embodiments, the tape splicing device 100 may omit the first mounting base 50 and the second mounting base 60, or the first tape splicing mechanism 10, the second tape splicing mechanism 30, the glue preparation mechanism 20, and the pressing mechanism each include a mounting base, and each mounting base is independently provided.

[0059] In a specific application, the second mounting base 60 is located above the first mounting base 50. Therefore, the second tape splicing mechanism 30, the glue preparation mechanism 20, and the second pressing plate 42 are all located above the first tape splicing mechanism 10 and the first pressing plate 41, so that the pressing mechanism can apply force to the tape. In this case, the thickness direction of the tape is parallel to the vertical direction, and the tape conveying direction is perpendicular to the vertical direction. Figure 1 The X direction is the conveying direction of the material belt. Figure 1 It is conceivable that, in other occasions, the second mounting base 60 and the first mounting base 50 may not be arranged in an up-down manner, and may be arranged left-right or front-back, which is not limited here.

[0060] See Figure 3 and Figure 5 The first tape connecting mechanism 10 includes a first suction plate 11, which is used to absorb the first material tape 200. Figure 4 and Figure 6 The second tape splicing mechanism 30 includes a second suction plate 31 for sucking the second material tape 300. Vacuum suction is used to absorb the material tape to prevent damage. It is understood that in other embodiments, the first tape splicing mechanism 10 and the second tape splicing mechanism 30 can also use other methods to fix or pick up the material tape.

[0061] Generally, before splicing, the previous tape needs to be cut to form the end of the tape, thereby reducing the occurrence of flying tape.

[0062] For further information, see Figure 3 The tape splicing device 100 further includes a cutting mechanism 70, which is mounted on the first mounting base 50 or the second mounting base 60. The first suction plate 11 and the second suction plate 31 are capable of relative movement in the thickness direction to compress the first material tape 200 held by the first suction plate 11. The cutting mechanism 70 is used to cut the first material tape 200 to form an end of the first material tape 200. The adhesive preparation mechanism 20 is capable of placing the adhesive tape 400 at the end of the first material tape 200.

[0063] In some embodiments, the first suction plate 11 is movably mounted on the first mounting base 50 in the thickness direction, and the second suction plate 31 is movably mounted on the second mounting base 60 in the thickness direction. Figure 5 The first belt connecting mechanism 10 further includes a first driving assembly 12, which is disposed on the first mounting base 50. The first suction plate 11 is connected to the first driving assembly 12. The first driving assembly 12 can drive the first suction plate 11 to move in the thickness direction to move closer to or away from the second suction plate 31. Figure 6 The second strip splicing mechanism 30 further includes a second drive assembly 32, which is mounted on the second mounting base 60. The second suction plate 31 is connected to the second drive assembly 32 and can drive the second suction plate 31 to move in the thickness direction, moving closer to or further away from the first suction plate 11. Thus, when cutting the first strip 200, the first drive assembly 12 and the second drive assembly 32 can operate simultaneously to move the first suction plate 11 and the second suction plate 31 closer to each other in the thickness direction, thereby clamping the first strip 200.

[0064] Specifically, the first driving assembly 12 and the second driving assembly 32 both use cylinders to respectively drive the first suction plate 11 and the second suction plate 31 to move in the thickness direction.

[0065] It is conceivable that in some other embodiments, one of the first suction plate 11 and the second suction plate 31 can be fixed, and the other can be movable relative to its corresponding mounting seat. Accordingly, the first belt connecting mechanism 10 omits the first drive component 12, or the second belt connecting mechanism 30 omits the second drive component 32.

[0066] For further information, see Figure 3 The first suction plate 11 includes first suction portions 111 arranged in sequence in the direction of conveying the material strip, and a first cutting gap 112 for accommodating the cutting mechanism 70 is formed between the two first suction portions 111. Figure 4 The second suction plate 31 includes two second suction portions 311 arranged sequentially in the direction of web conveyance. A second cutting gap 312 is formed between the two second suction portions 311 to accommodate the cutting mechanism 70. Thus, when the first suction plate 11 and the second suction plate 31 clamp the first web 200, the cutting mechanism 70 can cut the first web 200 through the first cutting gap 112 and the second cutting gap 312, ensuring that the first web 200 is completely severed.

[0067] In some embodiments, the vacuum suction of the two first suction parts 111 of the first suction plate 11 is independently controlled, and the vacuum suction of the two second suction parts 311 of the second suction plate 31 is independently controlled. It is understood that in other embodiments, the vacuum suction of the two first suction parts 111 can be controlled simultaneously, and the vacuum suction of the two second suction parts 311 can also be controlled simultaneously.

[0068] See Figure 5 The cutting mechanism 70 includes a cutting drive assembly and a cutter 71. The cutter 71 is connected to the cutting drive assembly. The cutting drive assembly is used to drive the cutter 71 to move to cut the first material strip 200. Specifically, the cutting drive assembly uses a cylinder to drive the cutter 71 to move, and the cutter 71 cuts in a scratching manner.

[0069] The tape splicing device 100 further includes a dust removal mechanism 80 , which is connected to an external dust removal device and is used to remove dust generated when the cutting mechanism 70 cuts the first material tape 200 . Specifically, the dust removal mechanism 80 and the cutting mechanism 70 are mounted together on the first mounting base 50 .

[0070] In some embodiments, the first suction plate 11 and the second suction plate 31 are capable of relative movement in the direction of web transport, allowing them to switch between a first state and a second state. Thus, when in the first state, the first suction plate 11 and the second suction plate 31 are capable of relative movement in the thickness direction and cooperate to clamp the first web 200, facilitating cutting of the first web 200. Furthermore, the second suction plate 31 is capable of positioning the second web 300 on the side of the adhesive tape 400 facing away from the first web 200. When in the second state, the first suction plate 11 and the second suction plate 31 allow the first pressing plate 41 and the second pressing plate 42 to move relative to each other in the thickness direction to press the first web 200 and the second web together.

[0071] Furthermore, the first suction plate 11 is fixed in the conveying direction of the material strip, and the second suction plate 31 can move in the conveying direction of the material strip so as to generate relative movement with the first suction plate 11. Figure 4 The second web-connecting mechanism 30 further includes a fourth drive assembly 33, which is connected to the second suction plate 31. The fourth drive assembly 33 is capable of driving the second suction plate 31 in the web conveying direction, thereby generating relative motion between the second suction plate 31 and the first suction plate 11. Specifically, the fourth drive assembly 33 utilizes a motor and a screw drive to drive the second suction plate 31 in the web conveying direction.

[0072] In other embodiments, the second suction plate 31 may be fixed in the direction of web conveyance, and the first suction plate 11 may be movable in the direction of web conveyance to generate relative motion between the second suction plate 31 and the first suction plate 11. The first web splicing mechanism 10 further includes a third drive assembly, to which the first suction plate 11 is connected. The third drive assembly can drive the first suction plate 11 to move in the direction of web conveyance, to generate relative motion between the second suction plate 31 and the first suction plate 11.

[0073] In a specific embodiment, see Figure 4 and Figure 6 The fourth drive assembly 33 is directly mounted on the second mounting base 60, the second drive assembly 32 is mounted on the fourth drive assembly 33, the second suction plate 31 is connected to the fourth drive assembly 33 through the second drive assembly 32, and the fourth drive assembly 33 can drive the second suction plate 31 to move in the conveying direction of the material belt through the second drive assembly 32.

[0074] See Figure 4 The second tape connection mechanism 30 further includes a rotating assembly 34, which is mounted on the second drive assembly 32. The second suction plate 31 and the glue preparation mechanism 20 are both mounted on the rotating assembly 34. The fourth drive assembly 33 is capable of driving the rotating assembly 34 in the direction of the tape feed, thereby driving the second suction plate 31 and the glue preparation mechanism 20 in the same direction. The rotating assembly 34 is capable of rotating the second suction plate 31 and the glue preparation mechanism 20, causing one of the second suction plate 31 and the glue preparation mechanism 20 to rotate so that it faces the first suction plate 11. Specifically, the rotating assembly 34 uses a pneumatic cylinder to drive the second suction plate 31 and the glue preparation mechanism 20 to rotate.

[0075] See Figure 4 When the second suction plate 31 faces the first suction plate 11, it can cooperate with the first suction plate 11 to clamp the first material tape 200, or place the second material tape 300 on the side of the tape 400 away from the first tape 400. Figure 7 When the glue preparation mechanism 20 faces the first suction plate 11, it can place the adhesive tape 400 on the first material strip 200. In some embodiments, the rotation assembly 34 can be rotated 90° to switch between the second suction plate 31 and the glue preparation mechanism 20 facing the first suction plate 11 and the other facing the first suction plate 11. It should be understood that in other embodiments, the rotation assembly 34 can also be rotated at other angles to achieve the corresponding switching, which is not limited here.

[0076] It should be noted here that the second suction plate 31 facing the first suction plate 11 means that the adsorption surface of the second suction plate 31 for adsorbing the second material tape 300 faces the adsorption surface of the first suction plate 11 for adsorbing the first material tape 200, and the glue preparation mechanism 20 facing the first suction plate 11 means that the picking surface of the glue preparation mechanism 20 for picking up the adhesive tape 400 faces the first suction plate 11 for adsorbing the first material tape 200.

[0077] The above arrangement enables free switching of the second suction plate 31 and the glue preparation mechanism 20 through the rotating assembly 34 , ensuring that the adhesive tape 400 and the second material tape 300 are placed in sequence, thereby improving work efficiency.

[0078] The adhesive preparation mechanism 20 includes an adhesive preparation board, on which the adhesive tape 400 is manually placed in advance, and the adhesive preparation board can absorb the adhesive tape 400 through adsorption force. Specifically, the adhesive preparation board is connected to the rotating assembly 34 in a quick-release manner to facilitate manual removal.

[0079] In some embodiments, see Figure 3 and Figure 5 The pressing mechanism further includes a fifth driving assembly 43. Specifically, the fifth driving assembly 43 is mounted on the first mounting seat 50. The first pressing plate 41 is connected to the fifth driving assembly 43. The fifth driving assembly 43 can drive the first pressing plate 41 to move in the thickness direction. Figure 4 The laminating mechanism further includes a sixth drive assembly 44, which is mounted on the second mounting base 60. The second laminating plate 42 is connected to the sixth drive assembly 44 and can drive the second laminating plate 42 to move in the thickness direction. Because the fifth drive assembly 43 and the sixth drive assembly 44 can respectively drive the first laminating plate 41 and the second laminating plate 42 to move in the thickness direction, the first laminating plate 41 and the second laminating plate 42 can respectively apply force to the first material strip 200 and the second material strip 300 from both sides of the adhesive tape 400, thereby ensuring the laminating effect.

[0080] It should be understood that in some other embodiments, the pressing mechanism may omit the fifth drive assembly 43 or the sixth drive assembly 44, and this is not limited here. The fifth drive assembly 43 and the sixth drive assembly 44 can respectively drive the first pressing plate 41 and the second pressing plate 42 in the thickness direction using a cylinder. Of course, in other embodiments, a motor and a screw drive can also be used to drive the first pressing plate 41 and the second pressing plate 42 in the thickness direction, and this is not limited here.

[0081] For further information, see Figure 3 The first suction plate 11 is provided with a through hole 113 in the thickness direction, and the first pressing plate 41 can be pressed on the first material strip 200 through the through hole 113 to avoid interference of the first suction plate 11 on the pressing of the first pressing plate 41.

[0082] In some embodiments, the first pressing plate 41 and the second pressing plate 42 are capable of relative movement in the direction of material conveyance, thereby switching between a third state and a fourth state. When the first pressing plate 41 and the second pressing plate 42 are in the third state, the first pressing plate 41 and the second pressing plate 42 allow the adhesive preparation mechanism 20 to place the adhesive tape 400 on the first material tape 200 and allow the second tape splicing mechanism 30 to place the second material tape 300 on the side of the adhesive tape 400 facing away from the first material tape 200. When the first pressing plate 41 and the second pressing plate 42 are in the fourth state, the first pressing plate 41 and the second pressing plate 42 are capable of relative movement in the thickness direction to press the first material tape 200, the adhesive tape 400, and the second material tape 300 together.

[0083] Furthermore, the first suction plate 11 and the first pressing plate 41 are both fixed in the conveying direction of the material strip, and the first pressing plate 41 and the first suction plate 11 are opposite to each other in the thickness direction. Figure 4 The sixth drive assembly 44 is connected to the fourth drive assembly 33. The fourth drive assembly 33 can drive the second pressing plate 42 to move in the material strip conveying direction through the sixth drive assembly 44. In this way, the second suction plate 31 and the second pressing plate 42 move synchronously in the material strip conveying direction, ensuring that when the second suction plate 31 and the first suction plate 11 are in the first state, the second pressing plate 42 and the first pressing plate 41 are in the third state. When the second pressing plate 42 and the first pressing plate 41 are in the fourth state, the second suction plate 31 and the first suction plate 11 are in the second state. This ensures that there is no interference between the placement of the second material strip 300 and the pressing of the material strips.

[0084] In some embodiments, at least one of the first pressing plate 41 and the second pressing plate 42 is a heating plate. Specifically, electric heating is adopted. The heating plate can heat the thermosetting tape 400 so that the tape 400 bonds the first material tape 200 and the second material tape 300 .

[0085] The tape splicing process using the tape splicing device 100 provided in the embodiment of the present application is as follows:

[0086] Manually adsorb the tape 400 on the preparation board in advance and prepare it.

[0087] See Figure 8 The first drive assembly 12 and the second drive assembly 32 respectively drive the first suction plate 11 and the second suction plate 31 to press the first material strip 200 adsorbed on the first suction plate 11. The cutting drive assembly drives the cutter 71 to cut the first material strip 200 and form a tail. The cut portion of the first material strip 200 is reeled up by the reeling mechanism.

[0088] See Figure 9The second drive assembly 32 returns to its original position, and the rotating assembly 34 rotates 90° so that the adhesive preparation plate faces the first material belt 200. The second drive assembly 32 drives the adhesive preparation plate to move closer to the first suction plate 11, and places the adhesive tape 400 on the first material belt 200.

[0089] See Figure 10 The second drive assembly 32 and the rotating assembly 34 return to their original positions, the second suction plate 31 absorbs the second material strip 300, and the fourth drive assembly 33 drives the second suction plate 31 to move so that the second material strip 300 faces the adhesive tape 400. The second drive assembly 32 moves to place the second material strip 300 on the adhesive tape 400.

[0090] See Figure 11 The second drive assembly 32 returns to its original position, and the fourth drive assembly 33 drives the second pressing plate 42 to a position where the adhesive tape 400 is placed, facing the first pressing plate 41 in the thickness direction. The fifth drive assembly 43 and the sixth drive assembly 44 operate simultaneously, causing the first pressing plate 41 and the second pressing plate 42 to clamp and heat the first material strip 200, the adhesive tape 400, and the second material strip 300, completing the strip splicing operation.

[0091] The tape splicing device 100 provided in the embodiment of the present application can not only improve the tape splicing efficiency, but also has strong bonding force after splicing, and will not cause debonding or breaking of the glue, which can meet the production process requirements of coiled materials (such as carbon paper or carbon felt).

[0092] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
