[0037] Refer back to Figures 2 to 4 , Figure 4This is a schematic structural diagram of the pressing and bearing assembly and the pressing mechanism in this embodiment. Further, the following driving mechanism 2 includes a following driving component 21 and a pressing and bearing component 22. The driving end of the following driving component 21 is connected to the pressing and bearing component 22. The pressing and bearing component 22 is slidably connected to the stacking and bearing platform 1 and surrounds the stacking group. The pressing mechanism 3 is arranged on the pressing and bearing component 22. The following driving component 21 drives the pressing and bearing component 22 to linearly move along with the height of the stacking group, and the pressing and bearing component 22 drives the pressing mechanism 3 to linearly move. The following driving component 21 is arranged on the lower surface of the stacking and bearing plate 11 and is located at a corner of the stacking and bearing plate 11.

The following driving member 212 is arranged at the lower end of the following driving carrier 211. The output end of the following driving member 212 is in transmission connection with the following lead screw 213 through the transmission of a driving wheel, a synchronous belt and a driven wheel. The following lead screw 213 is arranged along the height direction of the following driving carrier 211 and is rotatably connected to the following driving carrier 211 through two bearing seats. The following lead screw 213 is adjacent to the sliding position 112. The following linkage block 214 is sleeved on the following lead screw 213. The following driving member 212 drives the following lead screw 213 to rotate, driving the following linkage block 214 to linearly move on the following lead screw 213.

The four pressing sliding members 221 are respectively slidably connected to the four sliding positions 112. One of the pressing sliding members 221 is connected to the following linkage block 214. At the same time, this pressing sliding member 221 forms a sliding connection relationship with the following driving carrier 211 through the cooperation of a slide rail and a slider.

Preferably, the number of the following driving components 21 is two, and the two following driving components 21 are respectively located at the diagonals of the stacking and bearing plate 11. By linearly driving the pressing and bearing component 22 through the two following driving components 21, while providing sufficient driving force, the stability of the linear movement of the pressing and bearing component 22 and the pressing mechanism 3 is also ensured.Preferably, the pressing slider 221 forms a frame structure through the fixing columns to increase its own structural stability, thereby ensuring the stability of linear movement.

[0038] Continue to refer to Figure 4 、 Figure 5 and Figure 6 , Figure 5 which is a schematic structural diagram of the pressing mechanism in this embodiment, Figure 6 and which is a schematic structural diagram of the pressing mechanism from another perspective in this embodiment. Further, the pressing mechanism 3 includes a first pressing component 31 and a second pressing component 32. The first pressing component 31 and the second pressing component 32 are respectively arranged on the pressing and bearing component 22. The first pressing component 31 and the second pressing component 32 alternately press the stacking group. The number of the first pressing component 31 and the second pressing component 32 in this embodiment is two each. The two first pressing components 31 and the two second pressing components 32 are respectively arranged on the pressing and bearing frame 222, wherein the two first pressing components 31 are arranged oppositely, and the two second pressing components 32 are arranged oppositely. When pressing alternately, the two first pressing components 31 synchronously press the stacking group, and the two second pressing components 32 synchronously press the stacking group to ensure the pressing quality of the stacking group.

[0039] Refer back to Figure 5 and Figure 6, Further, the first pressing component 31 includes a first pressing carrier plate 311, a pressing sliding plate 312, a first pressing driving member 313, a second pressing carrier plate 314, a pressing sliding frame 315, a second pressing driving member 316, and a pressing plate 317. The first pressing carrier plate 311 is disposed on the pressing carrier frame 222, and the first pressing carrier plate 311 is parallel to the stacking carrier plate 11. The pressing sliding plate 312 is located above the first pressing carrier plate 311, and forms a sliding connection relationship with the first pressing sliding plate 311 through the cooperation of a slide rail and a slider. The driving end of the first pressing driving member 313 is connected to the pressing sliding plate 312, and drives the pressing sliding plate 312 to linearly move along a direction parallel to the stacking carrier plate 11. In this embodiment, the first pressing driving member 313 is a combination of a motor, a driving wheel, a synchronous belt, a driven wheel, and a lead screw pair. One end of the second pressing carrier plate 314 is connected to the pressing sliding plate 312, and the other end extends towards the stacking carrier plate 11. The second pressing carrier plate 314 is perpendicular to the pressing sliding plate 312. The pressing sliding frame 315 forms a sliding connection relationship with the second pressing carrier plate 314 through the cooperation of a slide rail and a slider. The driving end of the second pressing driving member 316 is connected to the pressing sliding frame 315. The pressing plate 317 is disposed on the pressing sliding frame 315. Specifically, one end of the pressing plate 317 is disposed on the pressing sliding frame 315, and the other end extends above the stacking position 12. The pressing plate 317 is parallel to the stacking carrier plate 11. The second pressing driving member 316 drives the pressing sliding frame 315 to linearly move along a direction perpendicular to the stacking carrier plate 11, thereby driving the pressing plate 317 to linearly move along a direction perpendicular to the stacking carrier plate 11, and the pressing plate 317 presses the stacked group carried on the stacking position 12. In this embodiment, the second pressing driving member 316 is also a combination of a motor, a driving wheel, a synchronous belt, a driven wheel, and a lead screw pair. Thus, through the cooperative driving of the first driving member 313 and the second driving member 316, the pressing plate 317 can be linearly moved along directions parallel to and perpendicular to the stacking carrier plate 11. The structure and operating principle of the second pressing component 32 are the same as those of the first pressing component 31, and will not be elaborated here. After a component is stacked on the stacked group at the stacking position 12, following the driving component 21 to drive the pressing carrier frame 222 to be lifted to a suitable height as a whole, driving the first pressing component 31 and the second pressing component 32 to be lifted accordingly. Then, the first driving member 313 drives the pressing plate 317 to approach above the stacked group, and the second driving member 316 then drives the pressing plate 317 to press down, pressing the stacked group, and realizing the pressing of the component by the first pressing component 31.After that, the next component is placed on the stacking group. At this time, the pressing plate 317 of the first pressing group 31 is located between two adjacent components. Then, the second pressing component 32 presses the next component. After that, while the second pressing component 32 remains in the pressed state, the first pressing component 31 moves upward a certain distance, for example, the thickness distance of the component. Then, the pressing plate 317 of the first pressing component 31 is withdrawn from between two adjacent components. Then, the second pressing component 32 continues to press down to complete the pressing of the next component, and so on. The first pressing component 31 and the second pressing component 32 alternately press the stacked components. When the height of the stacking group increases beyond the stroke of the first pressing component 31 and the second pressing component 32, the driving component 21 continues to drive the first pressing component 31 and the second pressing component 32 to lift as a whole, finally realizing the stacking of the entire stacking group. The spaces at the four corners of the avoidance space 111 respectively provide avoidance spaces for the pressing actions of the first pressing component 31 and the second pressing component 32 along the direction perpendicular to the stacking carrier plate 11. Preferably, the end of the pressing plate 317 has an inclined surface 3171, and the inclined surface 3171 is formed on the upper surface of the pressing plate 317. Through the setting of the inclined surface 3171, it is convenient for the withdrawal action of the pressing plate 317.

[0040] Preferably, the pressing mechanism 3 further includes a clamping assembly 33. The clamping end surface of the clamping assembly 33 faces the stacking group. In this embodiment, the number of the clamping assemblies 33 is four, and the four clamping assemblies 33 are respectively arranged on two first pressing assemblies 31 and two second pressing assemblies 32. It can be understood that after the upper end plates are stacked, the upper and lower end plates need to be screwed in by screws so that the stacking group formed by the membrane electrode and the bipolar plates forms a stable structure. The clamping assembly 33 is provided to clamp and fix the screw, so as to facilitate the assembly of the screw and the fixation when the stacking group moves. Specifically, the clamping assembly 33 includes a clamping support plate 331, a first clamping driving member 332, a second clamping driving member 333 and a clamping member 334. The clamping support plate 331 is slidably connected to the pressing sliding plate 312 through the cooperation of a slide rail and a slider. The first clamping driving member 332 is arranged on the pressing sliding plate 312, and its output end is connected to the clamping support plate 331. The first clamping driving member 332 drives the clamping support plate 331 to linearly move along a direction parallel to the stacking carrier plate 11. In this embodiment, the longitudinal section of the clamping support plate 331 is a "U" - shaped structure, which has a bottom plate 3311 and two end plates 3312. The two end plates 3312 are respectively located on the opposite side walls of the pressing sliding plate 312. The bottom plate 3311 is located above the pressing sliding plate 312, and there is a gap between them. The two end plates 3312 of the clamping support plate 331 are slidably connected to the opposite side walls of the pressing sliding plate 312.

The second clamping driving member 333 drives the clamping member 334 to perform a clamping action. Specifically, the clamping member 334 includes a first clamping plate 3341 and a second clamping plate 3342. One ends of the first clamping plate 3341 and the second clamping plate 3342 are respectively slidably connected to the bottom plate 3311 through the cooperation of a slide rail and a slider, and the first clamping plate 3341 and the second clamping plate 3342 extend upward above the stacking carrier plate 11. The second clamping driving member 333 drives the first clamping plate 3341 and the second clamping plate 3342 to approach each other to achieve a clamping action. In this embodiment, the second clamping driving member 333 can adopt a double - acting cylinder. The first clamping driving member 332 and the second pressing driving member 316 cooperate to drive the first clamping plate 3341 and the second clamping plate 3342 to approach the stacking group. Then, the second clamping driving member 333 drives the first clamping plate 3341 and the second clamping plate 3342 to clamp the screw of the stacking group.Preferably, one end of the first clamping plate 3341 close to the stacking and bearing plate 11 is of a U-shaped structure.

The two first clamping notches 33411 are located on the same side of the U-shaped structure of the first clamping plate 3341. Similarly, one end of the second clamping plate 3342 close to the stacking and bearing plate 11 is of a U-shaped structure adapted to the first clamping plate 3341.

The second clamping notches 33421 are adapted to the first clamping notches 33411, and the two cooperate to form a circular hole. The two second clamping notches 33421 are formed on the same side of the U-shaped structure of the second clamping plate 3342 and are respectively opposite to the two first clamping notches 33411. In this way, when the second clamping driving member 333 drives the first clamping plate 3341 and the second clamping plate 3342 to approach and move away from each other, the two first clamping notches 33411 and the two second clamping notches 33421 cooperate to clamp and release the two screws. Preferably, a screw fixing post 335 is provided on the bottom plate 3311. The screw fixing post 335 is parallel to the stacking and bearing plate 11. An arc-shaped structure adapted to the screw is provided at the end of the screw fixing post 335, and a suction cup capable of adsorbing the screw is provided inside.

The output end of the stacked group transfer drive assembly 41 is connected to the stacked carrier table 1, and the stacked group transfer drive assembly 41 drives the stacked carrier table 1 to move linearly. The overall transfer of the stacked group is realized through the stacked group transfer mechanism 4, so as to facilitate the processing of the stacked group by other processes. For example, the operation of locking the screw rods on the upper end plate and the lower end plate is performed to fix the stacked group of membrane electrodes and bipolar plates.

[0043] Continue Figure 1 、 Figure 2 and Figure 9 , Figure 9This is a schematic structural diagram of the wire fixing component in this embodiment. Further, the wire arranging mechanism 6 includes a wire arranging component 61 and a wire fixing component 62. The wire arranging component 61 regularizes the wires of the stacked group, and the wire fixing component 62 fixes the regularized wires. It can be understood that there are wires on the components to be stacked, such as the inspection wires on the bipolar plates. When stacking, the above-mentioned wires need to be regularized and fixed to avoid affecting the stacking of the stacked group. The wire arranging component 61 is arranged on the surface of the stacking carrier plate 11 and is located on the side of the pressing carrier 222 away from the stacking position 12. The wire arranging component 61 includes a wire arranging support frame 611 and a wire arranging part 612. The wire arranging support frame 611 is vertically arranged on the stacking carrier plate 11, and the wire arranging part 612 is arranged at the upper end of the wire arranging support frame 611. The wire arranging part 612 has a "U" - shaped structure. When the component is transferred to the stacking position 12 for stacking, it passes through the "U" - shaped structure of the wire arranging part 612, and the wires of the component are regularized by the "U" - shaped structure. Preferably, the wire arranging support frame 611 is a telescopic support frame. The wire fixing component 62 is located between the wire arranging component 61 and the stacking position 12. The wire fixing component 62 includes a fixed carrier plate 621, a fixed plate 622, a fixed driving part 623 and a fixed limiting plate 624. The fixed carrier plate 621 is vertically arranged on the stacking carrier plate 11. The fixed driving part 623 is arranged on the fixed carrier plate 621, and its output end is connected to one end of the fixed plate 622. A fixed notch 6221 is formed at the other end of the fixed plate 622, and this fixed notch 6221 faces the fixed carrier plate 621. The fixed notch 6221 in this embodiment is an arc - shaped notch. Preferably, a semi - circular notch can be used. The fixed driving part 623 drives the fixed plate 622 to rotate so that the fixed notch 6221 can be buckled on the fixed carrier plate 621. The fixed driving part 623 in this embodiment can be a rotary cylinder. The fixed limiting plate 624 is located on the side of the fixed plate 622 close to the wire arranging support frame 611. Preferably, the fixed limiting plate 624 is adjacent to the fixed plate 622. One end of the fixed limiting plate 624 is arranged on the fixed carrier plate 621, and the other end extends towards the end of the fixed plate 622 with the fixed notch 6221. The fixed limiting plate 624 in this embodiment is an arc - shaped plate. Initially, the fixed driving part 623 drives the fixed plate 622 away from the fixed carrier plate 621. After the wire passes through the "U" - shaped wire arranging part 612, it then passes through the fixed limiting plate 624 and then passes above the fixed plate 622. At this time, the fixed limiting plate 624 supports and limits the wire. Then, the fixed driving part 623 drives the fixed plate 622 close to the fixed carrier plate 621, and the fixed notch 6221 is buckled on the fixed carrier plate 621 to fix the wire.
