Referring to fig. 1, the present invention provides a sheet-to-roll laminating apparatus 10 and a transfer mechanism 300. The sheet roll-to-roll bonding apparatus 10 includes a sheet material feeding mechanism 100, a bonding roller 200, and a transfer mechanism 300.
The sheet-to-roll attaching device 10 is used to attach a sheet material to a material tape. Sheet material supply mechanism 100 can provide sheet material at a first speed, a web of material to be bonded can be wrapped around bonding roller 200, and bonding roller 200 can drive the web of material to be fed at a second speed. The first speed and the second speed are both linear speeds, and the first speed is lower than the second speed.
The sheet-to-roll laminating apparatus 10 can be applied to the production of fuel cells, and the sheet is referred to as CCM sheet 21, and the web is referred to as frame web 30. The CCM sheet 21 is laminated to the frame tape 30 to form the first composite tape 40 shown in fig. 6, and the frame tape 30 can be used as an upper frame or a lower frame. The side of the frame material tape 30 opposite to the CCM sheet 21 is generally attached with a protective film material tape 31, and the side of the CCM sheet 21 opposite to the frame material tape 30 is generally attached with a support film sheet 23.
In the process of manufacturing the fuel cell, after the first composite tape 40 is obtained, further processing is required, for example, another frame tape is attached to the side of the first composite tape 40 on which the CCM sheets 21 are disposed, so as to complete the preparation of the five-in-one tape.
The sheet material feeding mechanism 100 sequentially cuts the CCM material tape 20 into CCM sheet materials 21 and supplies them, typically by continuous roll cutting, thereby achieving continuous feeding of the CCM sheet materials 21. The laminating roller 200 is typically driven by a separate drive member, such as a servo motor. The frame material tape 30 to be bonded is generally pre-coated with a hot melt adhesive during preparation, so the bonding roller 200 is generally a heating roller. Therefore, when the frame material tape 30 is wound around the laminating roller 200, the laminating roller 200 can activate the hot melt adhesive on the frame material tape 30 by heating so as to be laminated with the CCM sheet material 21. Of course, if the initial viscosity of the frame material tape 30 is high, the applying roller 200 may be a general pressing roller.
As shown in fig. 5, the frame tape 30 has a plurality of inner frames 301 sequentially formed in the extending direction, and the material of the inner frame 301 is hollowed out. In the lamination, a plurality of CCM sheet materials 21 are required to be aligned in sequence with the regions corresponding to the plurality of inner frames 301.
The transfer mechanism 300 is configured to receive the CCM sheets 21 provided by the sheet feeding mechanism 100, and sequentially transfer the CCM sheets 21 to the laminating roller 200, so that the CCM sheets 21 are laminated to the frame material tape 30 wound around the laminating roller 200.
Referring to fig. 2 to 4, the transfer mechanism 300 includes an endless track 310, a suction plate 320, a first cam 330, a first follower 340, and a speed change assembly 350.
The circular rail 310 is fixedly disposed and can be fixed to a frame (not shown). The suction plate 320 is provided in plurality, and the plurality of suction plates 320 can slide along the circular rail 310, so as to switch between a material receiving position and a fitting position. The suction plate 320 can receive and adsorb the CCM sheet 21 supplied from the sheet supply mechanism 100 at the receiving position, and can cooperate with the laminating roller 200 at the adhering position, so that the adsorbed CCM sheet 21 is adhered to the frame material tape 30 wound around the laminating roller 200.
Furthermore, at the receiving position, at least two suction plates 320 are generally densely distributed, that is, two adjacent suction plates 320 are close to each other. Thus, the suction plate 320 can continuously receive the CCM sheet materials 21, and a skip distance does not need to be formed between two adjacent CCM sheet materials 21, thereby being beneficial to saving materials and improving efficiency.
In the embodiment, the suction plates 320 have an arc-shaped plate structure, and a curvature center of each suction plate 320 coincides with a center of the circular track 310. Therefore, when a plurality of suction plates 320 are densely distributed at the material receiving position, a larger arc-shaped plate structure can be spliced together, and the larger arc-shaped plate structure can be well attached to the annular rail 310, so that the transition between two adjacent suction plates 320 is smoother. Further, when the suction plate 320 is engaged with the bonding roller 200, the surface thereof can be brought into contact with the surface of the bonding roller 200 more favorably.
The first cam 330 is disposed concentrically with the annular track 310 and is rotatable about an axis. During the operation of the frame attaching device 10, the rotation speed of the first cam 330 is fixed. Specifically, the transferring mechanism 300 further includes a transmission shaft 360, the transmission shaft 360 is rotatably disposed through the circular track 310 and connected to the first cam 330, and the transmission shaft 360 is disposed coaxially with the first cam 330. The transmission shaft 360 may be in transmission connection with an external power assembly such as a motor, a rotary cylinder, etc., so as to drive the first cam 330 to rotate. The surface of the first cam 330 is circumferentially opened with a plurality of first cam grooves 331 arranged at intervals, and each of the first cam grooves 331 includes a parallel section 3311 extending in the axial direction of the first cam 330 and an inclined section 3312 inclined with respect to the parallel section 3311.
The number of the first followers 340 corresponds to the number of the suction plates 320, and the plurality of first followers 340 are respectively mounted to the plurality of suction plates 320. Further, each of the first followers 340 is capable of sliding in the axial direction of the endless track 310 with respect to the suction plate 320 on which it is located. Specifically, a guide rail pad (not shown) is installed on the lower side of the suction plate 320, a linear guide rail (not shown) extending along the axial direction of the annular rail 310 is installed on the guide rail pad, the slider connecting plate 341 is slidably installed on the linear guide rail through a slider, and the first follower 340 is fixed on the slider connecting plate 341.
Further, a plurality of first followers 340 are slidably provided to the plurality of first cam grooves 331, respectively, so that the suction plate 320 can slide along the endless track 310 by the first cam 330. The rotational torque of the first cam 330 may be transmitted to the corresponding suction plate 320 by the first follower 340, thereby driving the suction plate 320 to slide. During the sliding of the suction plate 320 along the endless track 310, since the first follower 340 can also slide along the suction plate 320, the position of the first follower 340 can be switched within the parallel section 3311 and the inclined section 3312 of the first cam groove 331.
Specifically, when the first follower 340 is located within the parallel section 3311, the angular velocities of the first follower 340 and the suction plate 320 coincide with the angular velocity of the first cam 330. Therefore, by properly setting the rotation speed of the first cam 330, the suction plate 320 can slide along the circular track 310 at a second speed; when the first follower 340 is located at the inclined section 3312, the first follower 340 not only rotates with the first cam 330, but also slides along the inclined section 3312. At this time, the actual angular velocity of the suction plate 320 is required to be added to the angular velocity of the first cam 330, based on the angular velocity of the first cam 330, of the first follower 340 with respect to the first cam 330. The trajectory of the first follower 340 within the inclined section 3312 can determine the magnitude of the additional angular velocity. Therefore, by properly setting the shape of the first cam groove 331, the suction plate 320 can be slid along the endless track 310 at the first speed.
The speed changing assembly 350 can slide the first follower 340 along the axial direction of the circular track 310. Specifically, when the suction plate 320 enters the material receiving position, the speed changing assembly 350 can drive the first follower 340 to enter the inclined section 3312. At this time, the first follower 340 slides within the inclined section 3312, and the suction plate 320 slides along the circular rail 310 at a first speed. When the suction plate 320 moves out of the receiving position, the speed changing assembly 350 can drive the first follower 340 to enter the parallel section 3311 from the inclined section 3312. At this time, the speed of the sliding of the suction plate 320 along the endless track 310 will be switched from the first speed to the second speed.
It follows that the suction plate 320 can be switched to different speeds at different positions. Specifically, the suction plate 320 can pass through the material receiving position at a first speed, so that the suction plate and the CCM sheet material 21 are kept relatively stationary at the material receiving position, and the CCM sheet material 21 is smoothly received; further, the suction plate 320 can pass through the bonding position at the second speed. In this way, the CCM sheet 21 on the suction plate 320 can be attached to the frame tape 30 on the attaching roller 200 in synchronization with the cooperation of the attaching roller 200 and the suction plate 320.
Although the feeding speed of the CCM sheet materials 21 is less than the linear speed of the laminating roller 200 (i.e., the tape-feeding speed of the frame tape 30), the frame tape 30 can be continuously fed in the laminating process through the transition of the plurality of suction plates 320, thereby significantly improving the production efficiency of the fuel cell.
Since the interval between the parallel sections 3311 of the adjacent two first cam grooves 331 is fixed. Further, before the suction plate 320 carrying the CCM sheet 21 enters the joining position, the corresponding first followers 340 each move to the parallel section 3311 of the first cam groove 331. Therefore, by reasonably setting the distance between two adjacent parallel segments 3311, two adjacent suction plates 320 can keep a preset distance, so that the distance between two adjacent CCM sheet materials 21 entering the attaching position can be conveniently controlled, and a plurality of CCM sheet materials 21 can be aligned with a plurality of inner frames 301 on the frame material belt 30 one by one.
Further, the distance between the inclined sections 3312 of the adjacent two first cam grooves 331 is smaller than the distance between the parallel sections 3311. Thus, when the suction plates 320 move to the material receiving position and the first follower 340 enters the inclined section 3312, the first follower 340 can drive the two adjacent suction plates 320 to approach each other, so that the suction plates 320 are densely distributed at the material receiving position.
Specifically, in the present embodiment, the circular track 310 includes two concentric circular sliding rails (not shown) disposed opposite to each other, two ends of each suction plate 320 are slidably disposed on the two circular sliding rails, and the first cam 330 is located between the two circular sliding rails. When the first cam 330 drives the suction plate 320 to slide along the circular slide rail through the first follower 340, the suction plate 320 is stressed more evenly.
More specifically, two ends of each suction plate 320 are disposed on two circular slide rails through the arc-shaped sliding blocks 321, and the curvature centers of the arc-shaped sliding blocks 321 coincide with the circle centers of the circular slide rails. The arc-shaped sliding block 321 is more attached to the surface of the circular sliding rail and is not easy to block. In this way, the suction plate 320 can be smoothly slid along the endless track 310.
Further, in the present embodiment, the speed changing assembly 350 includes a second cam 351, a plurality of links 352, and a plurality of second followers 353.
The second cam 351 is positioned at one side of the first cam 330 and is fixedly disposed with respect to the circular track 310. Specifically, the second cam 351 may be fixed to the frame. The surface of the second cam 351 is provided with a second cam groove 3511, and the second cam groove 3511 extends along the circumferential direction of the second cam 351. The width of the second cam groove 3511 (i.e., the dimension h shown in fig. 4) varies in the extending direction of the second cam groove 3511.
The number of the links 352 corresponds to the number of the first followers 340 and the second followers 353. Wherein, a plurality of connecting rods 352 are respectively connected with a plurality of first followers 340, and one end of each connecting rod 352 far away from the first followers 340 is provided with a second follower 353. A plurality of second followers 353 are provided to the second cam groove 3511. Also, the suction plate 320 slides along the ring rail 310, and the second follower 353 is carried along the second cam groove 3511.
When the second follower 353 slides along the second cam groove 3511, it is engaged with the second cam groove 3511 and moves the link 352 in the axial direction of the annular rail 310, i.e., the left-right direction shown in fig. 3 and 4. Specifically, when the suction plate 320 enters the material receiving position, the second follower 353 drives the corresponding connecting rod 352 to drive the first follower 340 to enter the inclined section 3312. The second follower 353 interacts with the second cam 351 such that the first follower 340 can slide at a uniform speed within the inclined section 3312. Accordingly, the suction plate 320 can slide along the endless track 310 at the first speed by the cooperation of the first cam 330, the first follower 340, the second cam 351, and the second follower 353.
When the suction plate 320 moves out of the material receiving position, the connecting rod 352 drives the first follower 340 to enter the parallel section 3311 from the inclined section 3312. The second follower 353 interacts with the second cam 351 such that the first follower 340 can be held at the parallel section 3311. At this time, the suction plate 320, the first follower 340, and the first cam 330 are in accordance with the angular velocity, so that the suction plate 320 can slide along the endless track 310 at the second velocity.
Further, the direction and distance in which the link 352 moves in the axial direction of the annular rail 310 are determined by the width h of the second cam groove 3511. It can be seen that the above requirements can be met only by reasonably designing the width h of the second cam groove 3511, so that the sliding speed of the suction plate 320 at different positions of the annular rail 310 can be automatically adjusted.
Taking fig. 3 and 4 as an example, the second cam 351 is located at the right side of the first cam 330, and the width h of the portion of the second cam groove 3511 corresponding to the material receiving position is greater than the width h of the other portions. Therefore, when the suction plate 320 enters the material receiving position, the connecting rod 352 drives the first follower 340 to the right, so that the first follower 340 enters the inclined section 3312. When the suction plate 320 moves out of the receiving position, the connecting rod 352 drives the first follower 340 to the left, so that the first follower 340 enters the parallel section 3311.
Further, in this embodiment, the speed changing assembly 350 further includes an elastic member 354, the elastic member 354 provides an elastic force to the first follower 340, and the elastic force can push the first follower 340 from the parallel portion 3311 to the inclined portion 3312 when the suction plate 320 enters the material receiving position. Thus, the suction plate 320 is decelerated to a first speed. When the suction plate 320 moves out of the receiving position, the connecting rod 352 drives the first follower 340 to overcome the elastic force, and the first follower 340 enters the parallel section 3311 from the inclined section 3312. Thus, the suction plate 320 is accelerated to the second speed.
It can be seen that the second follower 353 cooperates with the second cam groove 3511 by providing a force to move the first follower 340 from the inclined section 3312 into the parallel section 3311, while a force to move the first follower 340 from the parallel section 3311 into the inclined section 3312 is provided by the resilient member 354. In this manner, the second follower 353 only needs to be in contact with one side (right side in the drawing) of the second cam groove 3511 in the axial direction of the second cam 351, so that the second follower 353 can be effectively prevented from being stuck during sliding along the second cam groove 3511.
Furthermore, in the present embodiment, each suction plate 320 is provided with a guide post 322 and a spring guide rod 323 extending along the axial direction of the circular track 310, the guide post 322 is sleeved with a linear bearing 324, a bearing mounting plate 325 is fixedly arranged on the linear bearing 324, the elastic member 354 is a compression spring sleeved on the spring guide rod 323, and the compression spring supports the bearing mounting plate 325 against the slider connecting plate 341.
Specifically, the guide post 322 and the spring guide 323 can be fixed on the arc-shaped sliding block 321. The elastic force of the elastic member 354 is transmitted to the linear bearing 324 through the bearing mounting plate 325, thereby driving the linear bearing 324 to slide along the guide post 322 and acting on the slider attachment plate 341 through the bearing mounting plate 325. Thus, the connecting plate 341 pushes the first follower 340 to push the first follower 340 from the parallel portion 3311 into the inclined portion 3312.
Specifically, in this embodiment, the speed change assembly 350 further includes a third follower 355, the third follower 355 is mounted to the bearing mounting plate 325, and the bearing mounting plate 325 abuts against the slider connection plate 341 through the third follower 355. The third follower 355 directly contacts the slider coupling plate 341, and the bearing mounting plate 325 acts on the slider coupling plate 341 through the third follower 355. The third follower 355 can roll with respect to the surface of the slider coupling plate 341 in the process of pushing the slider coupling plate 341 to move in the axial direction of the endless track 310. In this manner, the friction between the third follower 355 and the slider coupling plate 341 is small, which helps to reduce wear, thereby making the movement of the suction plate 320 more accurate and enabling the extension of the life span of the apparatus.
In the sheet roll attaching apparatus 10, the suction plate 320 receives the sheet material at the receiving position, and then the sheet material can be transferred to the attaching station and attached to the material tape. When the suction plate 320 enters the receiving position, the first follower 340 slides along the inclined section 3312 of the first cam groove 331 to switch the suction plate 320 to the first speed, and the suction plate 320 can be kept in conformity with the feeding speed of the sheet. After the suction plate 320 carrying the sheet moves out of the set position, the first follower 340 enters the parallel section 3311 of the first cam groove 331, so that the suction plate 320 can be accelerated to the second speed, thereby achieving synchronization with the laminating roller 200. The plurality of suction plates 320 continuously circulate along the endless track 310, and continuously receive the sheet material supplied from the sheet material supply mechanism 100 and continuously transfer the sheet material to the bonding position. So, the material area can realize walking in succession at the laminating in-process to showing the efficiency that promotes the piece and laminate to rolling up.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
