Description

Technical Field

[0001] The present invention belongs to the technical field of carbon paper transportation, and specifically relates to equipment for carbon paper firewood stacking, and more particularly to a carbon paper feeding system and a feeding method for preparing electrode sheets. Background Art

[0002] Carbon paper is the core carrier of the gas diffusion layer of the electrode sheet, and its loading efficiency is one of the core factors restricting the efficiency of electrode sheet preparation.

[0003] In conventional carbon paper feeding systems, friction between adjacent sheets of stacked carbon paper during loading creates an electrostatic attraction effect, which can cause multiple layers of carbon paper to be pulled together during the gripping process, severely impacting single-sheet loading and efficiency. While inserting a separator between adjacent sheets of carbon paper can prevent simultaneous extraction of multiple layers, it reduces the amount of carbon paper in the stack, impacting overall loading efficiency.

[0004] Therefore, how to reduce the impact of the static environment on the accuracy of single-sheet feeding without affecting the feeding efficiency of carbon paper is a technical problem that needs to be solved urgently.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0074] Research has found that carbon paper loading systems used in related technologies often extract multiple sheets of carbon paper during loading and grabbing. This leads to uneven thickness of the membrane electrode gas diffusion layer during subsequent electrode sheet preparation, directly affecting the current distribution and output performance of the fuel cell. Using separators to separate adjacent carbon paper sheets reduces the amount of carbon paper in each material tray, affecting carbon paper loading efficiency.

[0075] Based on the above research, the embodiment of the present disclosure provides a carbon paper feeding system and feeding method for electrode sheet preparation. Through the cooperation of the dividing plate 422 and the pushing block 210, the top carbon paper 500 is tightly pressed against the bottom surface of the dividing plate 422, and the grasping mechanism 300 is used to grasp the carbon paper 500 and the top surface of the next layer of material to avoid interlayer adhesion caused by electrostatic adsorption. While not affecting the loading efficiency, the accuracy of single-sheet loading is improved.

[0076] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0077] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0078] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0079] See also Figure 1 and Figure 2At least one embodiment provides a carbon paper feeding system for preparing an electrode sheet, comprising: a working platform 100; a feeding mechanism 200, which is arranged on the working platform 100 and is used to transport a material tray 400; a grabbing mechanism 300, which is arranged above the feeding mechanism 200 and is used to grab the carbon paper 500 in the material tray 400 to complete the feeding; wherein, the material tray 400 comprises: a tray body 410, and at least one supporting assembly 420 is provided on the top surface; the supporting assembly 420 comprises: four limiting columns 421, and the four limiting columns 421 are arranged relative to each other to form a cubic stacking space 423 for The carbon paper 500 is stacked; wherein, the four limiting columns 421 are arranged in pairs, the two groups of limiting columns 421 are arranged in parallel, and the top surface of each group of limiting columns 421 is connected to a dividing plate 422; a discharge port 424 is reserved between the two dividing plates 422; the stacked carbon paper 500 is pushed by the pushing block 210 of the loading mechanism 200, so that the top carbon paper 500 is abutted against the bottom surface of the dividing plate 422, and the grasping mechanism 300 grasps the top carbon paper 500, so that the dividing plate 422 separates the top carbon paper 500 from the top surface of the next layer of material to avoid bringing out the next layer of material, so that the top carbon paper 500 is taken out from the discharge port 424 to complete the loading.

[0080] By cooperating with the stacking space 423 formed by the four limiting columns 421 and the dividing plate 422, the top carbon paper 500 is tightly pressed against the bottom surface of the dividing plate 422 under the action of the pushing block 210, and the grasping mechanism 300 is used to grasp the carbon paper 500 and separate the top surface of the next layer of material, avoiding interlayer adhesion caused by electrostatic adsorption, and improving the accuracy of single-sheet loading without affecting the loading efficiency.

[0081] The grabbing direction of the grabbing mechanism 300 is as follows: Figure 5 As shown in F1, when the carbon paper 500 is separated, Figure 5 Separation is performed as shown in the direction of F2.

[0082] See also Figure 2 and Figure 3 The position where the limiting pillars 421 abut against the stacked carbon paper 500 is provided with a notch 4211 ; the notches 4211 of the four limiting pillars 421 are arranged opposite to each other to form a cubic stacking space 423 for stacking the carbon paper 500 .

[0083] By providing the notch 4211 in the limiting column 421 , a stable stacking space 423 is formed, which reduces interlayer displacement of the carbon paper 500 during transportation, reduces interlayer friction, and thus reduces interlayer adsorption when the carbon paper 500 is separated.

[0084] See also Figure 3 and Figure 5 The bottom surface of the dividing plate 422 includes a separation surface 422a and a guide surface 422b; wherein, the separation surface 422a is arranged parallel to the top surface of the tray body 410; the guide surface 422b is inclined upward and arranged toward the discharge port 424, and the separation surface 422a is deep into the notch 4211; and, the intersection line 422c of the separation surface 422a and the guide surface 422b is arranged above the notch 4211.

[0085] The separation surface 422a is designed to be parallel to the top surface of the material tray 400 to ensure uniform transmission of the pushing force and avoid warping caused by uneven local force on the carbon paper 500; the guide surface 422b is inclined at an angle of 15-30 degrees to guide the grabbing of the carbon paper 500 so that the carbon paper 500 slides out along the guide surface 422b (such as Figure 5 As shown in F2 in FIG. 5 ), the success rate of separating the carbon paper 500 from each other is improved.

[0086] See also Figure 3 The separator plate 422 is made of a conductive material. A grounding plug 425 is provided on the side of the separator plate 422 away from the discharge port 424. A ground wire is electrically connected to the grounding plug 425 and is used to discharge static electricity generated by friction with the carbon paper 500. The separator plate 422 and the grounding plug 425 form a static discharge circuit, actively dissipating static electricity and reducing the static charge on the surface of the carbon paper 500. This reduces the interlayer adsorption force of the carbon paper 500 and improves the accuracy of gripping the carbon paper 500.

[0087] See also Figure 4 An air inlet 426 is provided on the side of the dividing plate 422 away from the discharge port 424; an air cavity 427 connected to the air inlet 426 is provided in the dividing plate 422, and the air cavity 427 is connected to the jet hole 428 of the guide surface 422b; the air inlet 426 is connected to an external ion wind generator, and is used to remove static electricity generated by the friction of the carbon paper 500, and at the same time, provide downward pressure on the next layer of material to prevent the grabbing mechanism 300 from bringing out the next layer of material.

[0088] The air inlet 426 is linked to the ion wind generator to form a directional airflow at the air jet hole 428 of the material separation plate 422, which can remove the static charge on the surface of the carbon paper 500 and exert pressure on the underlying material, thereby reducing the error rate of carbon paper 500.

[0089] See also Figure 6The loading mechanism 200 includes: a loading conveyor belt 220; a unloading conveyor belt 230, which is arranged side by side with the loading conveyor belt 220; two lifting transfer conveyor belts 240, which are respectively arranged in the loading conveyor belt 220 and the unloading conveyor belt 230, and the conveying direction of the lifting transfer conveyor belt 240 is arranged perpendicular to the conveying direction of the loading conveyor belt 220; the lifting transfer conveyor belt 240 is used to transfer the material tray 400 in the loading conveyor belt 220 to the unloading conveyor belt 230.

[0090] The loading conveyor 220 and unloading conveyor 230 are arranged in parallel, and cooperate with the lifting transfer conveyor 240 to realize the continuous transfer of material trays 400. Compared with traditional single-line operation, this design reduces manual tray changing time, enables continuous grasping of carbon paper 500, and improves the grasping efficiency of carbon paper 500.

[0091] Specifically, the grabbing mechanism 300 includes: a horizontal driving unit 310; two vertical driving units 320, both of which are arranged on the horizontal driving unit 310; a negative pressure adsorption frame 330 is arranged under each of the vertical driving units 320; wherein, in the stacked carbon paper 500, a padding paper 600 is arranged between adjacent carbon papers 500, and when the grabbing mechanism grabs the carbon paper 500, one of the negative pressure adsorption frames 330 is used to grab the carbon paper 500, and the other negative pressure adsorption frame 330 is used to grab the padding paper 600.

[0092] Two negative pressure suction frames 330 work in a time-sharing system: after one negative pressure suction frame 330 grabs the carbon paper 500, the other immediately grabs the next layer of padding paper 600. The dual negative pressure suction frame 330 design allows a double layer of material to be processed in a single cycle, improving the efficiency of grabbing the carbon paper 500 compared to traditional manual picking.

[0093] See also Figure 7 The present disclosure also provides a method for feeding carbon paper used in the above-mentioned electrode sheet preparation system. The method comprises:

[0094] S110 : The carbon paper 500 is stacked in the stacking space 423 of the material tray 400 .

[0095] S120 : The loading mechanism 200 transports the material tray 400 to the bottom of the grabbing mechanism 300 .

[0096] S130 : The pushing block 210 of the loading mechanism 200 pushes the stacked carbon papers 500 so that the top carbon paper 500 abuts against the bottom surface of the dividing plate 422 .

[0097] S140: The grabbing mechanism 300 grabs the top carbon paper 500, and the separating plate 422 separates the top carbon paper 500 from the top surface of the next layer of material.

[0098] S150: The grabbing mechanism 300 takes out the carbon paper 500, completing the feeding.

[0099] The cooperation of the stacking space 423 formed by the four limiting columns 421 and the distribution plate 422 allows the top carbon paper 500 to be tightly abutted against the bottom surface of the distribution plate 422 under the action of the push block 210, and separates the carbon paper 500 from the top surface of the material in the next layer through the cooperation of the grabbing mechanism 300, avoiding the interlayer adhesion caused by electrostatic adsorption, improving the accuracy of single feeding while not affecting the feeding efficiency.

[0100] After completing the grabbing of the carbon paper 500 once, the feeding method further comprises:

[0101] The push block 210 of the feeding mechanism 200 pushes the stacked carbon paper 500, so that the top pad paper 600 abuts against the bottom surface of the distribution plate 422;

[0102] The grabbing mechanism 300 grabs the top pad paper 600, so that the distribution plate 422 separates the top pad paper 600 from the top surface of the material in the next layer;

[0103] The grabbing mechanism 300 takes out the pad paper 600, completing the taking out of the pad paper 600.

[0104] The two negative pressure adsorption frames 330 work at different times: after one of the negative pressure adsorption frames 330 grabs the carbon paper 500, the other one immediately grabs the pad paper 600 in the next layer. The design of the double negative pressure adsorption frames 330 allows the single cycle to complete the processing of double layers of materials, improving the grabbing efficiency of the carbon paper 500 compared with the traditional manual picking.
