Description

Technical Field

[0001] This invention relates to the field of new energy film bonding technology, and in particular to equipment for feeding, conveying and bonding roll-to-roll sheets and membrane electrode carbon paper. Background Technology

[0002] With the development of hydrogen fuel cells, the current stand-alone equipment is not enough to meet the requirements for mass production. In order to increase production capacity, a fully automated roll-to-roll membrane electrode carbon paper bonding line has been developed.

[0003] In existing technologies, the transfer of carbon paper is mostly carried out by mechanical grippers or manual handling. Since it is made of flexible material, problems such as edge tearing and surface indentation are prone to occur during clamping and positioning, resulting in a high breakage rate during transfer. In addition, after dispensing, the glue residue on the dispensing nozzle drips directly, which not only contaminates the product and equipment but also wastes a lot of glue. The glue utilization rate is usually low, and the glue at the dispensing nozzle is prone to leakage and overflow when the machine is stopped, which increases the cost of equipment cleaning and consumable consumption. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding, conveying, and bonding device for roll-to-roll and film electrode carbon paper, addressing the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A feeding, conveying, and bonding device for roll-to-roll and film electrode carbon paper includes a first processing station and a second processing station. The first processing station includes a first rotating disk, and the second processing station includes a second rotating disk. Multiple positioning fixtures for positioning the carbon paper are arranged in a ring at equal intervals on both the first and second rotating disks. The device is characterized in that: a carbon paper feeding mechanism, a first carbon paper dispensing mechanism, and a first carbon paper laminating mechanism are sequentially arranged around the first rotating disk; a second carbon paper dispensing mechanism, a second carbon paper laminating mechanism, and a carbon paper unloading mechanism are arranged around the second rotating disk. The first carbon paper dispensing mechanism includes a dispensing robot arm disposed between the carbon paper feeding mechanism and the first carbon paper laminating mechanism. The driving end of the dispensing robot arm is equipped with a robot arm driving seat. The robot arm driving seat is equipped with a longitudinally arranged dispensing driving plate. The dispensing driving plate is equipped with a longitudinally arranged dispensing linear module. The driving end of the dispensing linear module is equipped with a dispensing lifting plate. The dispensing lifting plate is equipped with a plurality of parallel and spaced glue coating cylinders. The glue coating cylinders are arranged longitudinally, and a glue coating nozzle is installed at the bottom of the glue coating cylinder. A glue receiving seat is provided below the glue dispensing lifting plate. The glue receiving seat is formed with a glue receiving cavity to hold glue. The top of the glue receiving seat is formed with a glue receiving hole coaxially aligned with the glue dispensing nozzle. The side of the glue receiving seat is formed with a glue extraction hole, and a glue extraction connector is installed in the glue extraction hole. A bottom glue extraction plate is slidably connected to the bottom of the glue dispensing drive plate. The glue dispensing drive plate is equipped with a glue receiving lifting cylinder that drives the bottom glue extraction plate to move up and down. A horizontally arranged glue receiving telescopic cylinder is installed on the bottom glue extraction plate. The driving end of the glue receiving telescopic cylinder is connected to the glue receiving seat. The glue receiving seat is also equipped with a unblocking structure, which includes multiple unblocking needles that can move up and down. The first carbon paper film application mechanism includes a gantry transfer module, which is equipped with an adsorption seat for adsorbing and transferring the membrane electrode to the first rotating disk. A transfer robot is provided between the first rotating disk and the second rotating disk. The transfer robot includes a transfer linear module disposed between the first rotating disk and the second rotating disk. A transfer frame is installed at the drive end of the transfer linear module. A transfer lifting cylinder is installed on the transfer frame. An adsorption frame is installed at the drive end of the transfer lifting cylinder. The adsorption frame is equipped with multiple adsorption plates for adsorbing products.

[0006] The beneficial effects of this invention are: the first rotating disk and the second rotating disk operate synchronously, and the equidistantly distributed positioning fixtures provide a precise reference, ensuring the consistency of processing at each station; by changing the positioning fixtures, it can adapt to the production of carbon paper of various specifications and different types of film electrodes, increasing the versatility of the production line.

[0007] The adsorption rack adopts a multi-adsorption plate structure to increase the contact area with the carbon paper. Combined with vacuum adsorption pressure adjustment, it solves the problem of easy deformation of thin carbon paper materials. The entire process from carbon paper feeding to finished product unloading is unmanned. The roll-to-sheet process combined with precise positioning improves material utilization. After the positioning fixture reaches the first carbon paper dispensing mechanism, the dispensing robot arm drives the robot arm drive seat to swing laterally until it is vertically aligned with the positioning fixture. The dispensing linear module of the dispensing drive plate drives the dispensing lifting plate to descend, so that the glue applicator can descend synchronously, which facilitates the glue applicator nozzle to cooperate with the carbon paper of the positioning fixture and apply glue to the surface of the carbon paper. By using multiple glue applicators and applying glue simultaneously, the glue application efficiency is greatly improved. The glue-receiving hole at the top of the glue-receiving base is coaxially aligned with the glue-applying nozzle. After the glue-applying operation is completed, when the nozzle rises, the remaining glue will precisely drip into the glue-receiving chamber, preventing glue from randomly dripping onto the carbon paper, positioning fixture, or equipment. This eliminates problems such as carbon paper waste and fixture sticking caused by glue dripping, significantly improving product yield. Simultaneously, the glue-receiving base is driven by a glue-receiving lifting cylinder and a glue-receiving telescopic cylinder, allowing for precise movement and alignment according to the position of the glue-applying nozzle. During glue application, the glue-receiving telescopic cylinder retracts the glue-receiving base, preventing interference with the glue-applying cylinder and ensuring normal glue application operation. It boasts strong adaptability. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings.

[0017] like Figure 1-5 As shown, the equipment for feeding, conveying, and bonding roll-to-roll sheet and film electrode carbon paper includes a first processing station and a second processing station. The first processing station includes a first rotating disk 1, and the second processing station includes a second rotating disk 5. The first rotating disk 1 and the second rotating disk 5 are respectively arranged in a ring with multiple positioning fixtures 100 for positioning carbon paper. The carbon paper feeding mechanism 10, the first carbon paper dispensing mechanism 18, and the first carbon paper film bonding mechanism 2 are arranged in sequence around the first rotating disk 1. The second carbon paper dispensing mechanism 51, the second carbon paper film bonding mechanism 52, and the carbon paper unloading mechanism 53 are arranged around the second rotating disk 5.

[0018] The first rotating disk 1 and the second rotating disk 5 operate synchronously. The equidistantly distributed positioning fixtures 100 provide a precise reference to ensure the consistency of processing at each station. By changing the positioning fixtures 100, it can adapt to the production of carbon paper of various specifications and different models of film electrodes, increasing the versatility of the production line.

[0019] The carbon paper feeding mechanism 10 includes a feeding robot 11 and feeding platforms 12 arranged on the left and right sides of the feeding robot 11. The feeding platforms 12 are equipped with lifting support plates 13, which support the stacked carbon papers. The feeding robot 11 can individually pick up and transfer the carbon papers from the feeding support plates 13 to the positioning fixture 100 of the first rotating disk 1. A lifting cylinder is installed below the feeding platform 12, which drives the feeding support plates 13 to move up and down. Each time a carbon paper is picked up, the lifting cylinder raises the feeding support plates 13 by the height of one carbon paper, ensuring accurate carbon paper pickup by the feeding robot 11 each time. When the carbon paper on the left feeding support plate 13 is exhausted, the feeding robot 11 automatically switches to the right feeding platform 12 to pick up more paper. The replenishment personnel can replenish the stacked carbon paper on the left side while the right side is being fed, reducing downtime for replenishment.

[0020] In addition, a support column 14 is installed at the bottom of the feeding support plate 13, and the feeding platform 12 is formed with a bottom guide hole 15 for the support column 14 to pass through. The feeding support plate 13 is formed with multiple guide grooves 16, and the feeding platform 12 is equipped with vertical guide strips 17 that slide in conjunction with the guide grooves 16. The multiple vertical guide strips 17 position the stacked carbon paper sideways. The enclosure structure formed by the vertical guide strips 17 can reduce the impact of airflow on the stacking of carbon paper in the workshop and avoid the failure of picking up thin carbon paper due to airflow.

[0021] The carbon paper feeding mechanism 10 feeds carbon paper one by one into the positioning fixture 100 of the first rotating disk 1 for positioning. Then the first rotating disk 1 rotates, and the positioning fixture 100 rotates to align with the first carbon paper dispensing mechanism 18, so that the first carbon paper dispensing mechanism 18 can apply adhesive to the carbon paper in the positioning fixture 100.

[0022] The first carbon paper dispensing mechanism 18 includes a dispensing robot 19 disposed between the carbon paper feeding mechanism 10 and the first carbon paper laminating mechanism 2. A robot drive base 180 is mounted on the drive end of the dispensing robot 19. A longitudinally arranged dispensing drive plate 181 is mounted on the robot drive base 180. A longitudinally arranged dispensing linear module 182 is mounted on the dispensing drive plate 181. A dispensing lifting plate 183 is mounted on the drive end of the dispensing linear module 182. Multiple parallel-spaced glue-coating cylinders 184 are mounted on the dispensing lifting plate 183. The glue-applying cylinder 184 is arranged longitudinally, with a glue-applying nozzle 185 installed at the bottom. After the positioning fixture 100 is in place, the glue-applying robot arm drives the robot arm drive base 180 to swing laterally until it is vertically aligned with the positioning fixture 100. The glue-applying linear module 182 of the glue-applying drive plate 181 drives the glue-applying lifting plate 183 to descend, so that the glue-applying cylinder 184 descends synchronously. This facilitates the glue-applying nozzle 185 to cooperate with the carbon paper of the positioning fixture 100 to apply glue to the surface of the carbon paper. By using multiple glue-applying cylinders 184 and applying glue simultaneously, the glue-applying efficiency is greatly improved.

[0023] Below the dispensing lifting plate 183, there is a glue receiving seat 190. The glue receiving seat 190 is formed with a glue receiving cavity to hold glue. The top of the glue receiving seat 190 is formed with a glue receiving hole 191 that is coaxially aligned with the glue applicator 185. The side of the glue receiving seat 190 is formed with a glue extraction hole 192, and a glue extraction connector 193 is installed in the glue extraction hole 192. The bottom of the dispensing drive plate 181 is slidably connected to a bottom glue extraction plate 194. The dispensing drive plate 181 is provided with a glue receiving lifting cylinder 195 that drives the bottom glue extraction plate 194 to move up and down. The bottom glue extraction plate 194 is equipped with a horizontally arranged glue receiving telescopic cylinder 196. The driving end of the glue receiving telescopic cylinder 196 is connected to the glue receiving seat 190. In this embodiment, the glue-receiving hole 191 at the top of the glue-receiving base 190 is coaxially aligned with the glue-applying nozzle 185. After the glue-applying operation is completed, when the glue-applying nozzle 185 rises, the residual glue will drip precisely into the glue-receiving cavity, avoiding random glue dripping onto the carbon paper, positioning fixture, or equipment. This eliminates problems such as carbon paper scrapping and fixture sticking caused by glue dripping, significantly improving product yield. At the same time, the glue-receiving base 190 is driven by the glue-receiving lifting cylinder 195 and the glue-receiving telescopic cylinder 196, which can move precisely to align according to the position of the glue-applying nozzle 185. During glue application, the glue-receiving telescopic cylinder 196 drives the glue-receiving base 190 to retract, without interfering with the glue-applying cylinder 184, ensuring normal glue application operation and strong adaptability.

[0024] In addition, the residual glue collected in the dispensing chamber can be extracted and recycled by connecting a negative pressure device through the side glue extraction hole 192 and glue extraction connector 193. The residual glue that would otherwise be wasted can be reintroduced into the dispensing system for recycling, which significantly improves glue utilization and reduces glue procurement costs.

[0025] Furthermore, the adhesive receiving base 190 is also equipped with a unblocking structure 200, which includes unblocking needles 201. An unblocking base 202 is installed beside the adhesive receiving base 190, connected to it. A bottom drive frame 203 is installed at the bottom of the unblocking base 202, and an unblocking lifting cylinder 204 is installed on the bottom drive frame 203. The unblocking lifting cylinder 204 is equipped with a lifting drive plate 205, and multiple unblocking needles 201 are installed on the top of the lifting drive plate 205. The unblocking base 202 has longitudinally formed unblocking holes 206 for the unblocking needles 201 to pass through, and these holes 206 can be coaxially aligned with the adhesive applicator 184. The unblocking base 202 can be extended by the adhesive receiving telescopic cylinder 196 until it is vertically aligned with the adhesive applicator 184, i.e., coaxially aligned with the adhesive applicator nozzle 185. Driven by the unblocking lifting cylinder 204, the lifting drive plate 205 is raised, and multiple unblocking needles 201 simultaneously pass through the unblocking hole 206 and cooperate with the glue applicator 185, ensuring that each unblocking needle 201 can accurately extend into the corresponding glue applicator 185. With the drive of the unblocking lifting cylinder 204, multiple unblocking needles 201 can simultaneously complete the lifting and unblocking action. This can clean and unblock the hardened glue in the glue applicator 185, avoiding problems such as uneven glue dispensing and missed coating caused by clogging of the glue applicator 185, reducing the frequency of manual disassembly and cleaning, reducing equipment downtime, and ensuring continuous and stable operation of the production line. In addition, the coaxial layout of the unclogging hole 206 and the liquid receiving hole provides precise guidance for the unclogging needle 201, avoiding deviation or jamming during the lifting and lowering of the unclogging needle 201. This not only thoroughly cleans the cured glue residue inside the glue applicator 185 and prevents blockage of the glue dispensing channel, but also prevents the unclogging needle 201 from scratching the inner wall of the glue applicator 185 and causing damage, thus extending the service life of the glue applicator 185 and reducing the cost of replacing parts.

[0026] Furthermore, the dispensing lifting plate 183 is also equipped with a dispensing adjustment mechanism for adjusting the dispensing amount. The dispensing adjustment mechanism includes an adjusting rod 197 inserted into the coating cylinder 184. The bottom of the coating cylinder 184 is formed with a dispensing port 198 communicating with the coating nozzle 185. The dispensing port 198 is conical. A frustum-shaped adjusting block 199, coaxially aligned with the dispensing port 198, is installed at the bottom of the adjusting rod 197. The dispensing adjustment mechanism also includes a lifting drive component 207 that drives the adjusting rod 197 to move up and down in the coating cylinder 184. The conical dispensing port 198 and the coaxial frustum-shaped adjusting block 199 form a variable gap dispensing channel. When the lifting drive component 207 drives the adjusting rod 197 to move up and down, the radial gap between the frustum and the dispensing port 198 will change, thereby achieving precise fine-tuning of the dispensing amount. Without disassembling the parts, it can be dynamically adjusted during equipment operation, which can meet the dispensing amount requirements of carbon paper of different thicknesses and sizes, and can also adapt to the dispensing of glues of different viscosities. When the equipment is stopped or changed, or when the glue holder 190 retracts, the adjusting rod 197 can be lowered by the lifting drive component 207, so that the truncated cone adjusting block 199 is fully embedded in the conical glue outlet 198, thereby sealing the glue outlet 198 and preventing glue leakage when the equipment is stopped.

[0027] Preferably, the lifting drive component 207 is a lifting cylinder.

[0028] Furthermore, the dispensing lifting plate 183 is equipped with a horizontally arranged dispensing top plate 186. The top of the glue-applying cylinder 184 is connected to the dispensing top plate 186. The dispensing top plate 186 is formed with a glue supply port 187 connected to the glue-applying cylinder 184 and a pneumatic hole 188. It is also formed with an adjustment hole 189 into which the adjustment rod 197 is inserted. A cylinder drive plate 208 is installed above the dispensing top plate 186. The cylinder drive plate 208 is equipped with an adjustment lifting cylinder. The drive end of the adjustment lifting cylinder is connected to the top of the adjustment rod 197.

[0029] The top plate integrates three types of functional holes: glue supply port 187, pneumatic hole 188, and adjustment hole 189. It also connects to the top of the multi-coating cylinder 184. The glue supply, air pressure adjustment, and glue dispensing volume adjustment structures are all arranged in the top area of ​​the dispensing lifting plate 183, which greatly reduces the vertical space occupied by the equipment and makes the dispensing module structure more compact.

[0030] In one embodiment, the pneumatic hole 188 of the dispensing top plate 186 can be connected to a pneumatic system. By adjusting the air pressure, the flowability of the adhesive in the dispensing cylinder 184 can be controlled: for high-viscosity adhesives, the air pressure can be increased to assist in pushing the adhesive and avoid poor dispensing; for low-viscosity adhesives, the air pressure can be reduced to prevent excessively fast dispensing and resulting in an excessively thick adhesive layer. This design significantly expands the adhesive compatibility range of the equipment, eliminating the need to replace the dedicated adhesive supply module to meet different types of dispensing needs and improving process flexibility.

[0031] It should be noted that both the loading robot 11 and the dispensing robot 19 are planar robots, which have the advantages of high movement speed and high precision.

[0032] After the adhesive application is completed, the first rotating disk 1 continues to rotate, causing the positioning fixture 100 to rotate until it is aligned with the first carbon paper laminating mechanism 2. The first carbon paper laminating mechanism 2 includes a gantry transfer module 3, which is provided with an adsorption seat 36 for adsorbing and transferring the membrane electrode to the first rotating disk 1.

[0033] Furthermore, the first carbon paper laminating mechanism 2 also includes a longitudinally arranged conveyor plate 21. The conveyor plate 21 is equipped with an unwinding shaft 22 for unwinding the film electrode and a take-up shaft 23 for winding the waste film. The conveyor plate 21 is also equipped with multiple conveyor shafts 24 for feeding the film belt forward. Below the gantry transfer module 3, there is a conveyor seat 25 and a screw drive mechanism 26 that drives the conveyor seat 25 to move along the forward direction of the film electrode. The conveyor seat 25 is equipped with a conveyor shaft 27 that cooperates with the film belt. The conveyor seat 25 can move along the forward direction of the film electrode.

[0034] There are two take-up shafts 23. One take-up shaft 23 is used to collect waste from the top film, and the other take-up shaft 23 is used to collect waste from the bottom film. The take-up shafts 23 rotate under the drive of the motor to achieve winding and waste collection. After the top film is peeled off, the individual whole film electrode is exposed facing upward. Then, under the movement of the conveyor seat 25, the individual whole film electrode can be matched with the adsorption seat 36 of the gantry transfer module 3. The adsorption seat 36 can adsorb the film electrode.

[0035] The gantry transfer module 3 includes a transfer support frame 31. The transfer support frame 31 has an adsorption transverse linear module 32 arranged along its length. The drive end of the adsorption transverse linear module 32 is equipped with a transfer gantry frame 33. The transfer gantry frame 33 is equipped with a longitudinally arranged adsorption longitudinal linear module 34. The drive end of the adsorption longitudinal linear module 34 is equipped with a rotary cylinder 35. The adsorption seat 36 is installed on the drive end of the rotary cylinder 35. The adsorption longitudinal linear module 34, in conjunction with the adsorption transverse linear module 32, drives the adsorption seat 36 to move back and forth and to move up and down, so as to transfer the membrane electrode onto the first rotating disk 1 to be bonded to the carbon paper.

[0036] The rotary cylinder 35 can align the adsorption seat 36 to prevent the misaligned membrane electrode from sticking to the carbon paper, thereby further improving the sticking accuracy.

[0037] When bonding the carbon paper to the membrane electrode, the peeled membrane electrode is adsorbed by the adsorption seat 36, and then moved along the length of the gantry transfer module 3 to above the positioning fixture 100. Then, it is precisely bonded longitudinally to achieve bonding between the carbon paper and the membrane electrode. A transfer robot 4 is provided between the first rotating disk 1 and the second rotating disk 5. After the bonding between the carbon paper and the membrane electrode is completed, the first rotating disk 1 continues to rotate, causing the positioning fixture 100 to rotate until it aligns with the transfer robot 4. The transfer robot 4, in cooperation with the transfer linear module 40, the transfer lifting cylinder 42, and the adsorption plate 49, transfers the first bonded carbon paper to the positioning fixture 100 of the second rotating disk 5 for secondary processing.

[0038] The transfer robot 4 includes a linear transfer module 40 positioned between the first rotating disk 1 and the second rotating disk 5. A transfer frame 41 is mounted on the drive end of the linear transfer module 40. A transfer lifting cylinder 42 is mounted on the transfer frame 41. An adsorption frame 43 is mounted on the drive end of the transfer lifting cylinder 42. The adsorption frame 43 is equipped with multiple adsorption plates 49 for adsorbing the product. The adsorption frame 43 uses a multi-adsorption plate structure to increase the contact area with the carbon paper. Combined with vacuum adsorption pressure adjustment, this solves the problem of easy deformation of thin carbon paper materials. The entire process from carbon paper loading to finished product unloading is unmanned. The roll-to-sheet process, combined with precise positioning, improves material utilization.

[0039] Specifically, the adsorption frame 43 is equipped with an upright guide rod 44, the transfer and lifting cylinder 42 is equipped with a guide frame 45, the guide frame 45 is equipped with a guide sleeve 46 that slides with the guide rod 44, the bottom of the guide rod 44 is connected to the adsorption frame 43, and a connecting plate 47 is installed at the bottom of the adsorption frame 43. A connecting rod 48 is provided between the connecting plate 47 and the adsorption plate 49. When the adsorption frame 43 moves up and down, the sliding cooperation between the guide rod 44 and the guide sleeve 46 can improve the stability during the lifting and lowering process, ensure that the adsorption plate 49 is vertically aligned with the positioning fixture 100, and ensure the accuracy of adsorption.

[0040] In the second rotating disk 5, the positioning fixture 100 sequentially passes through the second carbon paper dispensing mechanism 51, the second carbon paper film-applying mechanism 52, and the carbon paper unloading mechanism 53. It dispenses adhesive onto the film electrode with carbon paper attached, and then applies another layer of carbon paper to the top before unloading via the carbon paper unloading mechanism 53. The carbon paper unloading mechanism 53 includes a unloading robot 6. The drive end of the unloading robot 6 is equipped with an unloading bracket 61. The unloading bracket 61 includes a first mounting strip 62 and second mounting strips 63 installed at both ends of the first mounting strip 62. The second mounting strips 63 are arranged horizontally and vertically relative to the first mounting strip 62. An unloading suction cup 64 is installed on the second mounting strip 63. The first mounting strip 62 has a first adjusting groove 65 formed along its length. The second mounting strip 63 has a first tightening member 66 that is loosely connected to the first adjusting groove 65. The second mounting strip 63 also has a second adjusting groove 67 formed along its length. The unloading suction cup 64 has a second tightening member 68 that is loosely connected to the second adjusting groove 67.

[0041] The first adjustment groove 65 of the first mounting strip 62 can adjust the distance between the two ends of the second mounting strip 63 laterally, and the second adjustment groove 67 of the second mounting strip 63 can adjust the arrangement position of the feeding suction cup 64 longitudinally. The first tensioning member 66 and the second tensioning member 68 adopt a quick-release bolt design. The adjustment process does not require special tools. Only three steps of manual loosening, adjusting and tightening are required to complete the layout calibration of the feeding suction cup 64.

[0042] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0043] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
