[0036] To further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail in conjunction with the accompanying drawings:

[0037] Refer to Figure 1 , the stacking production equipment in this embodiment includes a stacking loading device 1, a stacking transfer device 2, a stacking device 3 and an assembly and fixing device 4. The stacking loading device 1 and the stacking device 3 are respectively arranged on the transfer path of the stacking transfer device 2, and the assembly and fixing device 4 is adjacent to the stacking device 3. The stacking loading device 1 is used for loading stacked components, the stacking transfer device 2 transfers the stacked components to the stacking device 3 for stacking to form a stacked group, and the assembly and fixing device 4 receives the stacked group and fixes the stacked group to form a finished product. Through the cooperative setting of the stacking loading device 1, the stacking transfer device 2, the stacking device 3 and the assembly and fixing device 4, the processes of loading, stacking and assembly and fixing of the stacked components can be carried out smoothly and continuously, improving the production efficiency of the finished product, and the overall layout is reasonable, reducing the floor area of the equipment, and thus reducing the manufacturing cost of the enterprise.

[0038] Refer back to Figure 1, Further, the stacking production equipment in this embodiment further includes a transfer device 5 and a leak detection device 6. The transfer device 5 receives the finished products and transfers them to the leak detection device 6 for leak testing. The leak detection device 6 performs leak testing on the finished products to ensure the quality of the finished products. Preferably, the stacking production equipment in this embodiment further includes a blanking device 7 and a marking device 8. The blanking device 7 receives the finished products after leak testing and performs blanking, and the marking device 8 marks the finished products before blanking. The marking device 8 marks the identification codes of the blanked finished products to facilitate the production management of the finished products.

[0039] Refer back to Figure 1 , Furthermore, the stacking loading device 1 includes an end plate loading mechanism 11, a first stacking loading mechanism 12, and a second stacking loading mechanism 13. The end plate loading mechanism 11, the first stacking loading mechanism 12, and the second stacking loading mechanism 13 are respectively located on the transfer path of the stacking transfer device 2. The end plate loading mechanism 11 is used for loading the upper end plate and the lower end plate, the first stacking loading mechanism 12 is used for loading the first stacking plate, and the second stacking loading mechanism 13 is used for loading the second stacking plate. The stacking transfer device 2 first transfers the lower end plate loaded by the end plate loading mechanism 11, then transfers the first stacking plate and the second stacking plate loaded alternately by the first stacking loading mechanism 12 and the second stacking loading mechanism 13, and finally transfers the upper end plate loaded by the end plate loading mechanism 11 to complete the transfer and loading of each stacking component required for the stacking group stacking. In this embodiment, the first stacking plate is a bipolar plate, and the second stacking plate is a membrane electrode assembly. The end plate loading mechanism 11 can use tray loading. Two trays are arranged side by side, and the upper end plate and the lower end plate are respectively stacked on the two trays. The stacking transfer device 2 is located on one side of the end plate loading mechanism 11 close to the stacking device 3. The first stacking loading mechanism 12 and the second stacking loading mechanism 13 are respectively located on opposite sides of the end plate loading mechanism 11, and both the first stacking loading mechanism 12 and the second stacking loading mechanism 13 are adjacent to the stacking transfer device 2. Such a layout facilitates the transfer operation of the stacking transfer device 2. Among them, the second stacking loading mechanism 13 can use tray stacking loading. Preferably, the tray forms a stack of two second stacking plates to achieve double-station loading and improve the loading efficiency.

[0040] Continue to refer to Figures 1 to 3, Further, the first stacking and feeding mechanism 12 includes a storage part 121 and a rotation and switching part 122. The storage part 121 is used to store two rows of first stacking plates placed side by side. The rotation and switching part 122 is arranged on the moving path of the storage part 121, and the rotation and switching part 122 rotates and switches the storage part 121 that moves thereto. The rotation and switching part 122 is located on one side of the stacking transfer device 2. After pretreatment, the first stacking plates are placed in the storage part 121. The first stacking plates move with the storage part 121 to the position where the rotation and switching part 122 is located and are directly above the rotation and switching part 122. One row of the first stacking plates stored in the storage part 121 faces the stacking transfer device 2. After the stacking transfer device 2 transfers this row of first stacking plates to the stacking device 3, the rotation and switching part 122 drives the storage part 121 to rotate 180 degrees, so that the other row of first stacking plates stored in the storage part 121 faces the stacking transfer device 2, and then the stacking transfer device 2 transfers this row of first stacking plates. Preferably, two first stacking and feeding mechanisms 12 are arranged side by side. Through the above settings, feeding of a relatively large number of first stacking plates can be achieved at one time.

[0041] Continue to refer to Figure 3 , Figure 4 and Figure 5, Further, the material storage part 121 includes a material storage rack 1211, a material storage upper plate 1212, and a material storage lower plate 1213. The material storage upper plate 1212 and the material storage lower plate 1213 are sequentially arranged inside the material storage rack 1211 along the height direction of the material storage rack 1211. There is a gap between the material storage upper plate 1212 and the material storage lower plate 1213, and the two are facing each other, so that two side-by-side arranged material storage cavities 12111 are formed therebetween for storing two rows of juxtaposed first stacked plates. Specifically, a plurality of material storage grooves 12121 are respectively formed on the mutually facing surfaces of the material storage upper plate 1212 and the material storage lower plate 1213. The plurality of material storage grooves 12121 on the material storage upper plate 1212 are in one-to-one correspondence with the plurality of material storage grooves 12121 on the material storage lower plate 1213. The two facing material storage grooves 12121 clamp the opposite side edges of the first stacked plate, thereby completing the storage of the first stacked plate. Preferably, the distance between the material storage upper plate 1212 and the material storage lower plate 1213 can be adjusted relatively to adapt to first stacked plates of different specifications and sizes. The stacking and transferring device 2 picks up and feeds materials from the outside of the material storage cavity 12111. Preferably, the number of the material storage upper plate 1212 and the material storage lower plate 1213 is two. The other two material storage upper plates 1212 and the other two material storage lower plates 1213 form two other side-by-side arranged material storage cavities 12111 in the height direction of the material storage rack 1211 to double the material storage capacity of the material storage part 121. Preferably, the material storage part 121 further includes a material storage limiting component 1214. The material storage limiting component 1214 is arranged on the material storage upper plate 1212 and is close to the outer side edge of the material storage upper plate 1212. The material storage limiting component 1214 is used for laterally limiting the first stacked plate in the material storage cavity 12111 to prevent the material from being thrown off due to uneven bottom surface or obstacles. Specifically, the material storage limiting component 1214 includes a material storage limiting plate 12141, a material storage limiting guide 12142, and a material storage limiting clamping member 12143. The material storage limiting plate 12141 is located at the outer side edge of the material storage upper plate 1212 and can move relative to the material storage upper plate 1212. The material storage limiting guide 12142 is arranged on the upper surface of the material storage upper plate 1212 and is close to the outer side edge of the material storage upper plate 1212. The material storage limiting guide 12142 is connected to the material storage limiting plate 12141. In this embodiment, the number of the material storage limiting guides 12142 is three, and the three material storage limiting guides 12142 are respectively located at both ends and the middle position of the material storage upper plate 1212.Each storage limiting and guiding member 12142 includes a storage guiding fixed block 121421 and a storage guiding rod 121422. One end of the guiding fixed block 121421 is arranged on the upper surface of the storage upper plate 1212, and one end thereof is exposed outside the storage upper plate 1212. The storage guiding rod 121422 is inserted through one end of the guiding fixed block 121421 that is exposed outside the storage upper plate 1212. The storage guiding rod 121422 is slidably connected to the guiding fixed block 121421. The lower end of the storage guiding rod 121422 is connected to the storage limiting plate 12141. From the upper end to the lower end of the storage guiding rod 121422, the diameter of the storage guiding rod 121422 gradually becomes smaller, so that the storage guiding rod 121422 can be automatically limited and locked after sliding downward along the guiding fixed block 121421 for a certain distance. For example, when the storage limiting plate 12141 blocks the storage groove 12121. The storage limiting clamping member 12143 is arranged on the upper surface of the storage upper plate 1212 and is close to the middle part of the storage upper plate 1212. The storage limiting clamping member 12143 is detachably connected to the storage limiting plate 12141. The storage limiting clamping member 12143 drives the storage limiting plate 12141 to rise and fall. When rising, the storage groove 12121 is exposed from the storage limiting plate 12141, and the lateral limit on the first stacked plate disappears. When falling, the storage limiting plate 12141 blocks the storage groove 12121 to perform lateral limit on the first stacked plate. Specifically, the storage limiting clamping member 12143 includes a clamping rod 121431, a clamping driving rod 121432, a clamping elastic member 121433 and a clamping block 121434. One end of the clamping rod 121431 is rotatably connected to the upper surface of the storage upper plate 1212 through a bearing seat. The other end of the clamping rod 121431 has a wedge-shaped portion 1214311. The wedge-shaped portion 1214311 in this embodiment is in the shape of an inclined plane. The clamping driving rod 121432 is vertically connected to the clamping rod 121431. The clamping elastic member 121433 is sleeved on the clamping rod 121431. One end of the clamping elastic member 121433 abuts against the bearing seat, and the other end of the clamping elastic member 121433 abuts against the clamping driving rod 121432. The clamping elastic member 121433 in this embodiment is a spring. The clamping block 121434 is sleeved outside the clamping elastic member 121433. The clamping block 121434 has a channel (not shown in the figure) for the clamping driving rod 121432 to move along a direction parallel to the storage upper plate 1212 and a clamping notch 1214341 for the clamping driving rod 121432 to be clamped. The storage limiting plate 12141 is provided with a lifting block 121411 corresponding to the wedge-shaped portion 1214311. The lifting block 121411 has a lifting groove adapted to the wedge-shaped portion 1214311.When the storage part 121 moves while being full of materials, the clamping release driving rod 121432 is toggled, so that the clamping release driving rod 121432 is clamped in the clamping release notch 1214341. At this time, the clamping release elastic member 121433 is compressed, and the wedge-shaped portion 1214311 of the clamping release rod 121431 exits the lifting groove of the lifting block 121411, so that the storage limiting plate 12141 descends under its own gravity and blocks the storage groove 12121, performing a lateral limit on the first stacking plate. When reaching the feeding position of the first stacking plate, the clamping release driving rod 121432 is toggled to leave the clamping release notch 1214341. At this time, the clamping release elastic member 121433 resets and pushes the wedge-shaped portion 1214311 of the clamping release rod 121431 to insert into the lifting groove of the lifting block 121411, so that the storage limiting plate 12141 is lifted, and the storage groove 12121 is exposed from the storage limiting plate 12141, and the lateral limit on the first stacking plate disappears, and then the stacking transfer device 2 performs the operation of picking and transferring materials. Preferably, rollers are respectively arranged at the four corners of the bottom of the storage rack 1211 to facilitate the overall movement of the storage part 121.

[0042] Continue to refer to Figure 3 、 Figure 6 and Figure 7, further, the rotation switching part 122 includes a rotary cutting assembly 1221 and a jacking assembly 1222. The rotary cutting assembly 1221 includes a mounting base 12211, a rotating shaft 12212, a rotating plate 12213, a rotating gear 12214, a rotary cutting rack 12215 and a rotary cutting driving member 12216. The rotating shaft 12212 is rotatably arranged on the mounting base 12211. One end of the rotating shaft 12212 is connected to the rotating plate 12213. The rotating gear 12214 is sleeved on the rotating shaft 12212. The rotary cutting rack 12215 is slidably arranged on the mounting base 12211 through a guide rail and slider, and the rotary cutting rack 12215 meshes with the rotating gear 12214. The rotary cutting driving member 12216 is arranged on the mounting base 12211, and the output end of the rotary cutting driving member 12216 is connected to the rotary cutting rack 12215. The rotary cutting driving member 12216 is a cylinder. Further, the jacking assembly 1222 includes a jacking driving member 12221 and a jacking column 12222. The jacking driving member 12221 is arranged on the rotating plate 12213, and the jacking driving member 12221 is a cylinder. The jacking column 12222 is arranged at the output end of the jacking driving member 12221, and the jacking column 12222 is movably connected to the storage rack 111. In this embodiment, the number of the jacking driving members 12221 is four. Correspondingly, the number of the jacking columns 12222 is also four. The four jacking driving members 12221 are arranged at the four corners of the rotating plate 12213. The storage part 121 further includes four jacking plates 1215, and the four jacking plates 1215 are respectively arranged at the four corners near the bottom of the storage rack 1211. After the storage part 121 is in place, the four jacking columns 12222 are aligned with the four jacking plates 1215. The jacking driving member 12221 drives the jacking column 12222 to move towards the jacking plate 1215 of the storage rack 1211. The jacking plate 1215 has a positioning hole matching the shape of the jacking column 12222. The jacking column 12222 is inserted into the positioning hole, and the storage rack 1211 leaves the ground under the action of the jacking assembly 1222. Then, the rotary cutting driving member 12216 drives the rotary cutting rack 12215 to move. The rotary cutting rack 12215 drives the rotating gear 12214 to rotate. The rotating gear 12214 drives the rotating shaft 12212 to rotate, thereby driving the rotating plate 12213 to rotate. The rotating plate 12213 drives the storage rack 1211 to rotate 180 degrees to realize the switching of the two rows of first stacking plates on the storage part 121. Preferably, the rotary cutting assembly 1221 further includes supporting wheels 12217. The supporting wheels 12217 are arranged on the mounting base 12211 through a support frame, and the supporting wheels 12217 abut against the lower surface of the rotating plate 12213. In this embodiment, the number of the supporting wheels 12217 is four. The four supporting wheels 12217 support the rotating plate 12213 to drive the storage rack 1211 to rotate smoothly.Preferably, an auxiliary rotating assembly can also be provided directly above the center of the upper end of the storage rack 1211 to further increase the rotation center and rotational stability when the storage rack 1211 rotates. For example, a positioning hole is formed at the center of the upper end of the storage rack 1211, and the cooperation of a cylinder and a rotating shaft is adopted. Before the storage rack 1211 rotates, the cylinder drives the rotating shaft to insert into the positioning hole, and the rotating shaft forms a rotational fit with the storage rack 1211. To ensure that the storage part 121 accurately moves to a predetermined position, the storage device 1 of the present application further includes a guiding and limiting part 123. Refer back again. Figure 3, as shown in the figure, the guiding and limiting part 123 includes a first guiding and limiting component 1231 and a second guiding and limiting component 1232. The first guiding and limiting component 1231 is arranged above the material storage part 121, and it includes a U-shaped guiding groove 12311, a first guiding driving part 12312 and a locking column 12313. The output end of the first guiding driving part 12312 is connected to the locking column 12313, the locking column 12313 is directly opposite to the bottom of the U-shaped guiding groove 12311, and there is a through hole at the bottom of the U-shaped guiding groove 12311 for the locking column 12313 to pass through. The first guiding driving part 12312 is a cylinder. In specific applications, the top of the material storage rack 1211 has a column 12314. When moving the movable material storage rack 1211, the column 12314 moves along the U-shaped guiding groove 12311. The diameter of the column 12314 matches the groove width of the U-shaped guiding groove 12311. When the column 12314 moves to the bottom of the U-shaped guiding groove 12311, the first guiding driving part 12312 drives the locking column 12313 to extend, and the locking column 12313 is inserted into the U-shaped guiding groove 12311 to realize the limiting of the column 12314, thereby realizing the limiting of the material storage rack 1211 and preventing it from moving. The second guiding and limiting component 1232 includes two relatively arranged guiding plates 12321, a front limiting part 12322 and a rear limiting part 12323. A guiding groove 123211 is formed between the two guiding plates 12321, and the width of the guiding groove 123211 matches the width of the rollers of the material storage part 121, so that the rollers of the material storage part 121 can move along the length direction of the guiding groove 123211. Preferably, a blocking block 1232111 is arranged at one end of the guiding groove 123211 to block the rollers and prevent them from rolling out of the guiding groove 123211. The front limiting part 12322 includes a front stop cylinder 123221 and a front stop rod 123222. The front stop cylinder 123221 is arranged on one side of the guiding plate 12321 through a mounting vertical plate, and the front stop rod 123222 is connected to the output end of the front stop cylinder 123221. The rear limiting part 12323 includes a rear limiting cylinder 123231 and a rear limiting plate 123232. The rear limiting plate 123232 is slidably arranged through a guide rail slider, and the rear limiting plate 123232 is connected to the output end of the rear limiting cylinder 123231. In specific applications, the material storage rack 1211 is pushed along the guiding groove 123211. When the rear wheel abuts against the blocking block 1232111, the front stop cylinder 123221 drives the front stop rod 123222 to extend. Then, the rear limiting cylinder 123231 drives the rear limiting plate 123232 to move towards the material storage rack 1211, and the rear limiting plate 123232 pushes the material storage rack 1211 to abut against the front stop rod 123222. The front limiting part 12322 and the rear limiting part 12323 realize the limiting of the material storage rack 1211 and prevent it from moving.

[0043] Continue to refer to Figure 1 ,Figure 2 , Figure 8 , Figure 9 and Figure 10, Further, the stacking and transferring device 2 includes a stacking and transferring mechanism 21 and a transfer table 22. The transfer table 22 is provided on the transfer path of the stacking and transferring mechanism 21. The stacking and transferring mechanism 21 transfers the first stacked plate to the transfer table 22 for shaping, and transfers the shaped first stacked plate to the stacking device 3 for stacking. In this embodiment, the number of the stacking and transferring mechanisms 21 is two, and the two stacking and transferring mechanisms 21 are arranged side by side, both located between the end plate loading mechanism 11 and the stacking device 3. One of the stacking and transferring mechanisms 21 is adjacent to the first stacked plate loading mechanism 12 and is used for transferring and loading the first stacked plate, the upper end plate or the lower end plate. The other stacking and transferring mechanism 21 is adjacent to the second stacked plate loading mechanism 13 and is used for transferring and loading the second stacked plate, the upper end plate or the lower end plate. The transfer table 22 is located on the transfer path of the stacking and transferring mechanism 21 adjacent to the first stacked plate loading mechanism 12. Now, taking the stacking and transferring mechanism 21 adjacent to the first stacked plate loading mechanism 12 as an example, the loading and transfer will be described. The stacking and transferring mechanism 21 includes a stacking and transferring part 211, a material taking part 212 and a shaping part 213. The material taking part 212 and the shaping part 213 are respectively arranged on the stacking and transferring part 211. Preferably, the stacking and transferring mechanism 21 further includes an image sensing part 214, and the image sensing part 214 is arranged on the stacking and transferring part 211. The stacking and transferring part 211 is a four-axis or six-axis robot, and its end has a fixing plate 2111. The material taking part 212, the shaping part 213 and the image sensing part 214 are all arranged on the fixing plate 2111. The hand of the stacking and transferring part 211 is connected to the fixing plate 2111 through a quick-change joint 2112. The stacking and transferring part 211 drives the material taking part 212 to move to the corresponding first stacked plate loading mechanism 12. The material taking part 212 takes out the first stacked plate from the first stacked plate loading mechanism 12 and places it in the placement area 221 of the transfer table 22. The placement area 221 matches the shape of the first stacked plate. Then, the stacking and transferring part 211 drives the shaping part 213 to move to the corresponding first stacked plate. The shaping part 213 fixes and shapes the first stacked plate, and after shaping, conveys the first stacked plate to the stacking device 3 for stacking. Before the stacking and transferring part 211 drives the material taking part 212 or the shaping part 213 to move, the first stacked plate can be photographed and positioned by the image sensing part 214 to control the stacking and transferring part 211 to drive the material taking part 212 or the shaping part 213 to accurately clamp or fix and shape the first stacked plate. The material taking part 212 includes a material taking driving part 2121, a material taking clamping part 2122, a material taking detecting part 2123 and a material taking limiting part 2124. The material taking driving part 2121 is arranged on the fixing plate 2111, and the material taking driving part 2121 is a two-way cylinder. The material taking clamping part 2122 includes a material taking moving plate 21221 and material taking claws 21222 arranged at both ends of the material taking moving plate 21221. The material taking moving plate 21221 is slidably arranged on the fixing plate 2111 through a guide rail and a slider, and the material taking moving plate 21221 is connected to the output end of the material taking driving part 2121.The material taking and detecting member 2123 is arranged on the fixed plate 2111. The material taking and detecting member 2123 faces the first stacking and feeding mechanism 12 or the material taking and clamping member 2122. The material taking and detecting member 2123 is used to detect whether there is material in the storage cavity of the first stacking and feeding mechanism 12 or whether the material taking and clamping member 2122 successfully takes the material. The material taking and detecting member 2123 is a reflective photoelectric sensor. The material taking limiting member 2124 is arranged on the fixed plate 2111. The material taking limiting member 2124 is a limiting block. The material taking limiting member 2124 abuts against the material taking moving plate 21221 movably. In this embodiment, the number of the material taking and clamping members 2122 is two. Correspondingly, the number of the material taking limiting members 2124 is also two. The two material taking and clamping members 2122 are arranged oppositely. The two material taking limiting members 2124 are also arranged oppositely. The two material taking limiting members 2124 are located on both sides of the two material taking and clamping members 2122. When taking the material, the stacking transfer part 211 drives the material taking part 212 to correspond to the first stacking plate. The material taking driving member 2121 drives the two material taking moving plates 21221 to move towards each other. The material taking claws 21222 on the two material taking moving plates 21221 approach to clamp the first stacking plate. Then, under the drive of the stacking transfer part 211, the first stacking plate is transferred to the corresponding transfer platform. The material taking driving member 2121 drives the two material taking moving plates 21221 to move away from each other. The material taking claws 21222 on the two material taking moving plates 21221 move away to release the first stacking plate. The first stacking plate is placed in the placing area 221 of the transfer table 22. During the movement of the material taking moving plate 21221, the material taking limiting member 2124 limits the material taking moving plate 21221 so that it can only slide within a certain distance. In this way, it can be avoided that the material taking moving plate 21221 and the material taking claws 21222 affect the first stacking plate adjacent to the first stacking plate to be clamped in the first stacking and feeding mechanism 12 when taking the material. The shaping part 213 includes a shaping suction component 2131 and a shaping component 2132. The shaping suction component 2131 and the shaping component 2132 are both arranged on the fixed plate 2111. The shaping suction component 2131 includes a suction cup 21311 and a suction detecting member 21312. The suction cup 21311 is arranged on the fixed plate 2111. The suction cup 21311 faces the first stacking plate. The suction detecting member 21312 is arranged on the fixed plate 2111. The suction detecting member 21312 faces the first stacking plate. The suction detecting member 21312 is a reflective photoelectric sensor. Before the suction cup 21311 sucks the first stacking plate, the suction detecting member 21312 detects whether there is a first stacking plate at a predetermined position. If there is a first stacking plate at the predetermined position, it takes a picture for positioning and then sucks it. The shaping component 2132 shapes the first stacking plate. The shaping component 2132 includes a first shaping driving member 21321, a second shaping driving member 21322, a shaping clamping member 21323, a buffer member 21324 and a shaping limiting member 21325. The first shaping driving member 21321 is arranged on the fixed plate 2111. The first shaping driving member 21321 is a double-acting cylinder.The second shaping drive member 21322 is disposed on a slide plate 21326 that is slidably disposed on a fixed plate 2111 through a guide rail slider. The slide plate 21326 is connected to the output end of the first shaping drive member 21321 through a connecting block 21327. The shaping clamping member 21323 includes a shaping moving plate 213231 and shaping jaws 213232 provided at both ends of the shaping moving plate 213231. The shaping moving plate 213231 is connected to the output end of the second shaping drive member 21322. The buffer member 21324 is disposed on the fixed plate 2111. The buffer member 21324 is movably abutted against the connecting block 21327. The buffer member 21324 is a buffer. During the sliding process of the slide plate 21326, the buffer member 21324 plays a role of buffering and limiting. The shaping limiting member 21325 is disposed on the fixed plate 2111. The shaping material limiting member is a limiting block. The shaping limiting member 21325 is movably abutted against the shaping moving plate 213231. During the shaping process, the shaping limiting member 21325 limits the shaping moving plate 213231 so that it can only slide within a certain distance. In this way, it is avoided that its moving distance is too large and it collides with other components. In this embodiment, the number of the second shaping drive members 21322, the shaping clamping members 21323, the buffer members 21324, and the shaping limiting members 21325 is two. During shaping, the stacking and transferring portion 211 drives the shaping portion 213 to move to the first stacking plate on the corresponding transfer table. The first shaping drive member 21321 respectively drives the two second shaping drive members 21322 to slide towards each other along the guide rail slider until the shaping jaws 213232 respectively correspond to the four corners of the first stacking plate. The two second shaping drive members 21322 respectively drive the two groups of oppositely arranged shaping moving plates 213231 to move towards each other. The shaping moving plates 213231 drive the shaping jaws 213232 to move towards each other. The shaping jaws 213232 clamp and shape the four corners of the first stacking plate. It should be noted that the second shaping drive member 21322 close to the material taking portion 212 can be omitted. The shaping assembly 2132 and the material taking portion 212 share the material taking drive member 2121 of the material taking portion 212 for material taking and clamping and shaping, that is, the shaping moving plate 213231 and the material taking moving plate 21221 are simultaneously connected to the output end of the material taking drive member 2121. In this way, the production cost can be saved. In addition, the shared material taking drive member 2121 can be disposed on an external connecting plate connected to the fixed plate 2111. In this way, it is convenient to assemble and replace the material taking drive member 2121. The image sensing portion 214 includes an image sensor 2141 and a light source 2142. The image sensor 2141 is disposed on the fixed plate 2111. The light source 2142 is disposed at the image acquisition end of the image sensor 2141.In this embodiment, the image sensor 2141 is a CCD camera, and the light source 2142 is a plate-shaped LED lamp. In specific applications, the image sensor 2141 takes pictures of the first stacked board to collect images. Through the CCD positioning system, the control system of the loading and shaping device 2 controls the stacking transfer unit 211 to drive the material taking unit 212 or the shaping unit 213 to move, so as to achieve accurate material taking and shaping. When the image sensor 2141 takes pictures of the first stacked board, the light source 2142 plays an auxiliary lighting role to obtain clear images. The transfer table 22 has a first guide groove 222 and a second guide groove 223. The shape of the first guide groove 222 matches the shape of the shaping jaw 213232, and the shape of the second guide groove 223 matches the shape of the material taking jaw 21222. When the shaping jaw 213232 clamps the first stacked board, it moves along the first guide groove 222, and the first guide groove 222 guides the shaping jaw 213232 to ensure that it accurately clamps the first stacked board for shaping; when the material taking jaw 21222 clamps the first stacked board and transfers it to the transfer table 22, the material taking jaw 21222 moves along the first guide groove 222, and the first guide groove 222 guides the material taking jaw 21222 to ensure that it accurately places the first stacked board at the predetermined position in the placement area 221. Preferably, refer back. Figure 2 , an auxiliary stacking positioning part 23 is arranged on one side of the transfer table 22. The auxiliary stacking positioning part 23 is a combination of a CCD and a light source, which further positions the transferred first stacked board so that the position of the first stacked board when placed on the stacking device 3 for stacking is accurate. Of course, an auxiliary stacking positioning part can also be arranged on the side of the second stacking loading mechanism 13 close to the stacking transfer mechanism 21 to further position the loading of the second stacked board. It should be noted that the second stacked board does not need to be shaped. Therefore, in specific applications, the stacking transfer mechanism 21 close to the second stacking loading mechanism 13 does not have a transfer table and a shaping part.

Through the cooperation of the following driving mechanism 32 and the pressing mechanism 33, the pressing mechanism 33 can move following the stacking height of the stacking group and press the stacking group during the forming process, avoiding the dislocation and inclination of the stacking group and ensuring the stacking quality. Preferably, the stacking device 3 further includes a stacking group transfer mechanism 34. The transfer end of the stacking group transfer mechanism 34 is connected to the stacking carrier 31. The stacking group transfer mechanism 34 drives the stacking carrier 31 to be transferred to the assembly and fixing position of the assembly and fixing device 4. Preferably, the number of the stacking devices 3 is at least two, and at least two stacking devices 3 are arranged side by side. In this embodiment, the number of the stacking devices 3 is two, and the two stacking group transfer mechanisms 34 are arranged side by side, and they are respectively located on one side of the stacking transfer mechanism 21 away from the end plate feeding mechanism 11. The assembly and fixing device 4 is located on one side of the stacking group transfer mechanism 34 away from the stacking transfer mechanism 21 and is adjacent to it. The two stacking group transfer mechanisms 34 can alternately transfer the stacking carrier 31, and the assembly and fixing device 4 sequentially receives the stacking groups transferred by the two stacking devices 3 for assembly and fixing, so as to improve the overall production efficiency. Preferably, the stacking device 3 further includes a fixing mechanism 35. The fixing mechanism 35 is arranged on the stacking carrier 31, and its fixing end faces the stacking group. The fixing mechanism 35 fixes the stacking group during the transfer process to prevent the stacking group from tilting during the movement. Preferably, the stacking device 3 further includes a wire arranging mechanism 36. The wire arranging mechanism 36 is arranged on the stacking carrier 31. The wire arranging mechanism 36 regularizes and fixes the wires of the stacking group, thus avoiding the chaos at the stacking site and further ensuring the smooth progress of the stacking process.

The lower end plate, bipolar plates, membrane electrodes and upper end plate to be stacked are transferred by the stacking transfer device 2 and carried on the carrier main body 3121 for stacking. During the transfer, the lower end plate is transferred first, and then multiple bipolar plates and multiple membrane electrodes are transferred alternately and stacked on the lower end plate. Finally, the upper end plate is transferred. Starting from the transfer of the lower end plate, each stacking will form a stacking group. As the stacking progresses, the height of the stacking group continuously increases. The four corners of the avoidance position 3111 provide an avoidance space for the pressing mechanism 33 to press the stacking group, so as to facilitate the smooth pressing operation of the pressing mechanism 33. After the stacking is completed, the stacking group is transferred to the assembly and fixing device 4, and the upper end plate and the lower end plate are fixed by fixing components, such as screws, so that the entire stacking group forms a stable whole to form a finished product.

[0047] Continue to refer to Figures 13 to 15, further, the pressing mechanism 33 includes a first pressing assembly 331 and a second pressing assembly 332. The first pressing assembly 331 and the second pressing assembly 332 are respectively arranged on the pressing and carrying assembly 322. The first pressing assembly 331 and the second pressing assembly 332 alternately press the stacking group. In this embodiment, the number of the first pressing assembly 331 and the second pressing assembly 332 is two each. The two first pressing assemblies 331 and the two second pressing assemblies 332 are respectively arranged on the pressing and carrying member 3222, wherein the two first pressing assemblies 331 are arranged oppositely, and the two second pressing assemblies 332 are arranged oppositely. When pressing alternately, the two first pressing assemblies 331 synchronously press the stacking group, and the two second pressing assemblies 332 synchronously press the stacking group to ensure the pressing quality of the stacking group. Specifically, the first pressing assembly 331 includes a first pressing and carrying plate 3311, a pressing sliding plate 3312, a first pressing driving member 3313, a second pressing and carrying plate 3314, a pressing sliding frame 3315, a second pressing driving member 3316 and a pressing plate 3317. The first pressing and carrying plate 3311 is arranged on the pressing and carrying member 3222, and the first pressing and carrying plate 3311 is parallel to the stacking and carrying plate 311. The pressing sliding plate 3312 is located above the first pressing and carrying plate 3311, and it forms a sliding connection relationship with the first pressing and carrying plate 3311 through the cooperation of a slide rail and a slider. The driving end of the first pressing driving member 3313 is connected to the pressing sliding plate 3312, and it drives the pressing sliding plate 3312 to linearly move along a direction parallel to the stacking and carrying plate 311. In this embodiment, the first pressing driving member 3313 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 and carrying plate 3314 is connected to the pressing sliding plate 3312, and the other end extends towards the stacking and carrying plate 311. The second pressing and carrying plate 3314 is perpendicular to the pressing sliding plate 3312.

In this embodiment, the second pressing driving member 3316 is also a combination of a motor, a driving wheel, a synchronous belt, a driven wheel and a lead screw pair. In this way, through the combined driving of the first driving member 313 and the second driving member 316, the pressing plate 3317 can be linearly moved along directions parallel to and perpendicular to the stacking and carrying plate 311.The structure and operating principle of the second pressing component 332 are the same as those of the first pressing component 331, and will not be elaborated here. According to the height of the stack group stacked on the stacking bearing position 312, the driving component 321 drives the pressing bearing member 3222 to be lifted to a suitable height as a whole, driving the first pressing component 331 and the second pressing component 332 to be lifted accordingly. Then, the first driving member 313 drives the pressing plate 3317 close to the upper part of the stack group, and the second driving member 316 then drives the pressing plate 3317 to press down, pressing the stack group to realize the pressing of the first pressing component 331 on the stacking plate. After that, the next stacking plate is placed on the stack group. At this time, the pressing plate 3317 of the first pressing group 31 is located between two adjacent stacking plates. Then, the second pressing component 332 presses the next stacking plate. Then, while the second pressing component 332 remains in the pressing state, the first pressing component 331 moves upward a certain distance, and then the pressing plate 3317 of the first pressing component 331 is withdrawn from between two adjacent stacking plates. Then, the second pressing component 332 continues to press down to complete the pressing of the next stacking plate, and so on. Through the staggered pressing of the stack group by the first pressing component 331 and the second pressing component 332, when the height of the stack group increases beyond the stroke of the first pressing component 331 and the second pressing component 332, the driving component 321 continues to drive the first pressing component 331 and the second pressing component 332 to be lifted as a whole, finally realizing the stacking of the entire stack group. The spaces at the four corners of the avoidance position 3111 respectively provide avoidance spaces for the pressing actions of the first pressing component 331 and the second pressing component 332 along the direction perpendicular to the stacking bearing plate 311. Preferably, the end of the pressing plate 3317 has an inclined surface 3171, which is opened on the upper surface of the pressing plate 3317. Through the setting of the inclined surface 3171, it is convenient for the withdrawal action of the pressing plate 3317. Preferably, the pressing mechanism 33 further includes a clamping component 33. The clamping end of the clamping component 33 faces the stack group. The number of clamping components 33 in this embodiment is four, and the four clamping components 33 are respectively arranged on two first pressing components 331 and two second pressing components 332.

Specifically, the clamping component 33 includes a clamping support plate 3331, a first clamping driving member 3332, a second clamping driving member 3333, and a clamping member 3334. The clamping support plate 3331 forms a sliding connection relationship with the pressing sliding plate 3312 through the cooperation of a slide rail and a slider. The first clamping driving member 3332 is arranged on the pressing sliding plate 3312, and its output end is connected to the clamping support plate 3331. The first clamping driving member 3332 drives the clamping support plate 3331 to linearly move along the direction parallel to the stacking bearing plate 311.In this embodiment, the longitudinal section of the clamping support plate 3331 is a "U"-shaped structure, which has a bottom plate 33311 and two end plates 33312. The two end plates 33312 are respectively located on the opposite side walls of the pressing sliding plate 3312. The bottom plate 33311 is located above the pressing sliding plate 3312, and there is a gap between the two. The two end plates 33312 of the clamping support plate 3331 are slidably connected to the opposite side walls of the pressing sliding plate 3312. The second clamping driving member 3333 is arranged on the side of the bottom plate 33311 facing the pressing sliding plate 3312, and its output end is connected to the clamping member 3334. The second clamping driving member 3333 drives the clamping member 3334 to perform a clamping action.

The second clamping driving member 3333 in this embodiment can adopt a double-acting cylinder. The first clamping driving member 3332 and the second pressing driving member 3316 cooperate to drive the first clamping plate 33341 and the second clamping plate 33342 to approach the stacking group. Then, the second clamping driving member 3333 drives the first clamping plate 33341 and the second clamping plate 33342 to clamp the screw of the stacking group. Preferably, one end of the first clamping plate 33341 close to the stacking carrier plate 311 is a "U"-shaped structure, and two first clamping notches 333411 are formed at the end of the "U"-shaped structure of the first clamping plate 33341. The two first clamping notches 333411 are located on the same side of the "U"-shaped structure of the first clamping plate 33341. Similarly, one end of the second clamping plate 33342 close to the stacking carrier plate 311 is a "U"-shaped structure adapted to the first clamping plate 33341, and two second clamping notches 333421 are formed at the end of the "U"-shaped structure of the second clamping plate 33342.

The two second clamping notches 333421 are formed on the same side of the "U"-shaped structure of the second clamping plate 33342 and are respectively aligned with the two first clamping notches 333411. In this way, when the second clamping driving member 3333 drives the first clamping plate 33341 and the second clamping plate 33342 to approach and separate from each other, the two first clamping notches 333411 and the two second clamping notches 333421 cooperate to clamp and release the two screws. Preferably, a screw fixing post 3335 is arranged on the bottom plate 33311.The screw fixing column 3335 is parallel to the stacking carrier plate 311, has an arc-shaped structure adapted to the screw at the end, and has a suction cup inside that can adsorb the screw.

After the wire passes through the wire arranging part 3612 with a "U"-shaped structure, it then passes through the fixed limiting plate 3624, and then passes above the fixed plate 3622. At this time, the fixed limiting plate 3624 supports and limits the wire. Then, the fixed driving part 3623 drives the fixed plate 3622 to approach the fixed carrier plate 3621, and the fixed notch 36221 is buckled on the fixed carrier plate 3621 to fix the wire.

The preloading top plate 4342 is located above the preloading bottom plate 4341. The preloading top plate 4342 is parallel to the preloading bottom plate 4341 and the two are facing each other. In this embodiment, both the preloading bottom plate 4341 and the preloading top plate 4342 are rectangular plates, and the four corners of the two are respectively connected and fixed by the four preloading support columns 4343. The preloading support columns 4343 are perpendicular to the preloading bottom plate 4341 and the preloading top plate 4342 respectively, so that the entire preloading support frame 434 forms a stable frame structure. A preloading opening 43421 is provided in the middle of the preloading top plate 4342. In this embodiment, the preloading opening 43421 is a rectangular through opening, which facilitates the movement of the fixing component during feeding and preloading assembly. The preloading drive assembly 431 includes a preloading drive member 4311 and a preloading transmission member 4312. The output end of the preloading drive member 4311 is connected to the preloading transmission member 4312, and the preloading transmission member 4312 is connected to the preloading assembly 432. The preloading assembly 432 includes a preloading member 4321 and a preloading sliding member 4322. The two ends of the preloading sliding member 4322 are respectively connected to the preloading bottom plate 4341 and the preloading top plate 4342. The preloading sliding member 4322 is adjacent to the preloading opening 43421. The preloading member 4321 is slidably connected to the preloading sliding member 4322 and is connected to the preloading transmission member 4312. The preloading member 4321 preloads and bears the fixing component. The preloading drive member 4311 drives the preloading transmission member 4312, and the preloading transmission member 4312 drives the preloading assembly 432 to approach or move away from the preloading opening 43421. Among them, the preloading drive member 4311 is a drive motor, which is fixed to the preloading bottom plate 4341 through a bracket. The preloading transmission member 4312 includes a preloading driving wheel 43121, a preloading synchronous belt 43122, a plurality of idler wheels 43123, two driven wheels 43124, and two preloading transmission lead screws 43125.The output end of the pre-installed driving part 4311 is connected to the pre-installed driving wheel 43121. The pre-installed driving wheel 43121 is respectively connected to a plurality of idler wheels 43123 and two driven wheels 43124 through the pre-installed synchronous belt 43122. The two pre-installed transmission lead screws 43125 are respectively located at the diagonals of the pre-installed bottom plate 4341. The pre-installed transmission lead screws 43125 are perpendicular to the pre-installed bottom plate 4341. The two ends of the pre-installed transmission lead screws 43125 are respectively rotatably connected to the pre-installed bottom plate 4341 and the pre-installed top plate 4342. The two driven wheels 43124 are respectively sleeved on the two pre-installed transmission lead screws 43125. The plurality of idler wheels 43123 are respectively located between the pre-installed driving wheel 43121 and the two driven wheels 43124, and are respectively connected to the pre-installed synchronous belt 43122 for changing the direction of the pre-installed synchronous belt 43122 to avoid interference with other components. Thus, driven by the pre-installed driving part 4311, through the transmission of the pre-installed driving wheel 43121, the pre-installed synchronous belt 43122, the plurality of idler wheels 43123 and the two driven wheels 43124, the two pre-installed transmission lead screws 43125 can rotate synchronously. A pre-installed nut 43126 is sleeved on the pre-installed transmission lead screw 43125. The rotation of the pre-installed transmission lead screw 43125 becomes the linear movement of the pre-installed nut 43126. The pre-installed nut 43126 is connected to the pre-installed component 432. In this way, the pre-installed component 432 can be driven to perform a reciprocating linear motion between the pre-installed bottom plate 4341 and the pre-installed top plate 4342. The pre-installed sliding part 4322 includes four pre-installed sliding rods 43221 and a pre-installed sliding plate 43222. The two ends of the four pre-installed sliding rods 43221 are respectively connected to the pre-installed bottom plate 4341 and the pre-installed top plate 4342. The four pre-installed sliding rods 43221 are respectively located inside the four pre-installed support columns 4343. The pre-installed sliding rods 43221 are parallel to the pre-installed support columns 4343. The four corners of the pre-installed sliding plate 43222 are respectively slidably connected to the four pre-installed sliding rods 43221. The pre-installed sliding plate 43222 is connected to the pre-installed nut 43126.The pre-installed part 4321 is arranged on the pre-installed slide plate 43222. The pre-installed part 4321 is a frame body, on which a screw bearing position 43211 for carrying the fixing part is provided. The number and position of the screw bearing positions 43211 are adapted to the number and position of the screw holes to be assembled in the stacking group. When the pre-installed screw nut 43126 moves linearly, it drives the pre-installed slide plate 43222 to slide on the pre-installed slide rod 43221, driving the pre-installed slide plate 43222 to perform reciprocating linear motion between the pre-installed bottom plate 4341 and the pre-installed top plate 4342, so that the screw bearing position 43211 can approach or move away from the pre-installation port 43421. When the screw bearing position 43211 approaches the pre-installation port 43421, the feeding and transferring assembly 422 sequentially transfers the fixing parts to the screw bearing position 43211, and then the screw bearing position 43211 moves away from the pre-installation port 43421 again. When the stacking group arrives, the screw bearing position 43211 approaches the pre-installation port 43421 again, so that after the fixing part passes through the pre-installation port 43421, it is correspondingly assembled onto the stacking group. The screw bearing position 43211 in this embodiment can adopt a slot or a frame with a hexagonal structure, so as to facilitate the bearing of the end of the screw with a hexagonal nut. When the screw is arranged in the screw bearing position 43211, it is perpendicular to the pre-installed bottom plate 4341.

[0057] Continue to refer to Figure 22 and Figure 23, Further, the preloading mechanism 43 further includes a guiding component 433. The guiding component 433 guides the fixed components that the preloading component 432 moves. Preferably, the number of guiding components 433 is four. The four guiding components 433 are respectively arranged on the lower surface of the preloading top plate 4342 and adjacent to the four sides of the preloading port 43421 to guide the moving mechanical energy of the plurality of fixed components. Specifically, the guiding component 433 includes a guiding support plate 4331, a first guiding driving member 4332, a guiding sliding plate 4333, a second guiding driving member 4334, a third guiding driving member 4335, and a guiding member 4336. The longitudinal section of the guiding support plate 4331 is an "L"-shaped plate. One end of it is slidably connected to the lower surface of the preloading top plate 4342, and the other end of the guiding support plate 4331 extends towards the preloading bottom plate 4341 and is adjacent to the preloading port 43421. The first guiding driving member 4332 is arranged on the preloading top plate 4342, and its output end is connected to the guiding support plate 4331. The first guiding driving member 4332 drives the guiding support plate 4331 to move along a direction parallel to the preloading top plate 4342. The first guiding driving member 4332 in this embodiment is a cylinder. The guiding sliding plate 4333 is slidably connected to one end of the guiding support plate 4331 that extends towards the preloading bottom plate 4341, and the guiding sliding plate 4333 is adjacent to the preloading port 43421. The second guiding driving member 4334 is arranged on the guiding support plate 4331, and its output end is connected to the guiding sliding plate 4333. The second guiding driving member 4334 drives the guiding sliding plate 4333 to linearly move along a direction perpendicular to the preloading top plate 4342. The second guiding driving member 4334 in this embodiment can be a cylinder. The third guiding driving member 4335 is arranged on the side wall of the guiding sliding plate 4333 adjacent to the preloading port 43421, and its output end is connected to the guiding member 4336. The guiding member 4336 includes two guiding blocks 43361. The two guiding blocks 43361 are respectively slidably connected to the guiding sliding plate 4333, and semi-circular grooves are formed on the opposite sides of the two guiding blocks 43361. The semi-circular grooves of the two guiding blocks 43361 form a circular channel, and the circular channel is adapted to the fixed components. The third guiding driving member 4335 drives the two guiding blocks 43361 to approach and separate from each other. The third guiding driving member 4335 in this embodiment can be a double-acting cylinder. In this way, through the combined driving of the first guiding driving member 4332 and the second guiding driving member 4334, the guiding member 4336 is driven to approach or move away from the preloading port 43421, and the opening and closing control of the guiding member 4336 is realized through the third guiding driving member 4335. In specific applications, the number of the third guiding driving member 4335 and the guiding member 4336 is adapted to the screw bearing positions 43221 to guide the plurality of fixed components preloaded on the same side of the preloading port 43421.When the feeding and transferring assembly 422 transfers the fixing component through the preloading opening 43421, the third guiding and driving member 4335 drives the guiding member 4336 to open and remains in the open state. The first guiding and driving member 4332 drives the guiding member 4336 to approach the preloading opening 43421, so that the opened guiding member 4336 faces the preloading opening 43421. At this time, the second guiding and driving member 4334 remains undriven. In this way, after the fixing component moved by the feeding and transferring assembly 422 passes through the preloading opening 43421, it directly passes through the opened guiding member 4336 and is fed to the screw bearing position 43211, so that the subsequent guiding member 4336 can quickly perform clamping and guiding. At the same time, the preloading driving member 4311 can drive the screw bearing position 43211 to lift a certain distance, or lift to a position close to the preloading opening 43421 to receive the fixing component fed by the feeding and transferring assembly 422. The specific lifting height of the screw bearing position 43211 can be determined according to the length of the fixing component, so as to realize the receiving and bearing of fixing components of different lengths. Then, the preloading driving member 4311 drives the screw bearing position 43211 to descend again and move away from the preloading opening 43421. At this time, the third guiding and driving member 4335 can drive the guiding member 4336 to clamp, and a circular channel is formed by the semi-circular grooves of the two guiding blocks 43361 to guide the fixing component. Of course, the guiding member 4336 can also perform clamping and guiding after the screw bearing position 43211 descends in place. Then, after the slide plate of the bearing and stacking group is in place, the second guiding and driving member 4334 drives the clamped guiding member 4336 to lift and abut against the lower surface of the slide plate of the bearing and stacking group, so that the circular channel of the guiding member 4336 faces the through hole position of the slide plate of the bearing and stacking group. In this way, accurate guiding can be carried out for the lifting and assembling of the fixing component. After that, the preloading driving member 4311 drives the screw bearing position 43211 to lift again, driving the fixing component to lift along the guiding direction of the guiding member 4336 and approach the preloading opening 43421, so that after the threaded end of the fixing component passes through the preloading opening 43421, it accurately passes through the through hole of the slide plate of the bearing and stacking group and then passes through the through hole of the lower end plate of the stacking group. After that, the screw bearing position 43211 continues to lift until the fixing component passes through the upper end plate of the stacking group. At the same time, the third guiding and driving member 4335 drives the guiding member 4336 to open, and the first guiding and driving member 4332 and the second guiding and driving member 4334 cooperate to drive the guiding member 4336 away from the preloading opening 43421 to avoid the continuous movement of the screw bearing position 43211.

[0058] Continue to refer to 19 and Figure 24, Further, the press-fitting mechanism 44 includes a press-fitting drive assembly 441 and a press-fitting assembly 442. The output end of the press-fitting drive assembly 441 is connected to the press-fitting assembly 442. The press-fitting drive assembly 441 drives the press-fitting assembly 442 to move, and the press-fitting assembly 442 compresses the stacked group after assembling the fixing components. Preferably, the press-fitting mechanism 44 further includes a locking assembly 43. The locking assembly 43 receives the locking components transferred by the loading and transfer assembly 422 and locks the fixing components assembled on the stacked group. Specifically, the press-fitting drive assembly 441 includes a press-fitting drive member 4411, a press-fitting transmission member 4412, and a press-fitting guiding member 4413. The press-fitting drive member 4411 is disposed within the fixed bearing frame 412. Specifically, the press-fitting drive member 4411 is disposed on the lower plate 4122 through a bracket, and its output end is connected to the press-fitting transmission member 4412. The press-fitting transmission member 4412 consists of a driving wheel, a synchronous belt, a driven wheel, a press-fitting lead screw 44121, and a press-fitting lead plate 44122. The two ends of the press-fitting lead screw 44121 are respectively rotatably connected to the upper plate 4121 and the lower plate 4122 of the fixed bearing frame 412 through bearing seats, and the press-fitting lead screw 44121 is perpendicular to the pre-assembled bottom plate 4341. The press-fitting lead plate 44122 is sleeved on the press-fitting lead screw 44121, and the driven wheel is sleeved on the end of the press-fitting lead screw 44121. The output end of the press-fitting drive member 4411 is connected to the driving wheel, and the driving wheel is connected to the driven wheel through the synchronous belt. Thus, when the press-fitting drive member 4411 drives the driving wheel, it can sequentially drive the synchronous belt, the driven wheel, and the press-fitting lead screw 44121 to rotate, and then drive the press-fitting lead plate 44122 to linearly move along the press-fitting lead screw 44121. The press-fitting guiding member 4413 includes two press-fitting guide rods 44131. The two press-fitting guide rods 44131 respectively pass through the upper plate 4121 vertically and form a sliding connection relationship with the upper plate 4121 through linear bearings. The two press-fitting guide rods 44131 are respectively connected to the press-fitting lead plate 44122. When the press-fitting lead plate 44122 linearly moves, it drives the two press-fitting guide rods 44131 to linearly move. There are two groups of press-fitting drive assemblies 441, and the two groups of press-fitting drive assemblies 441 are respectively disposed within the two fixed bearing frames 412. Thus, a support and guiding structure composed of four press-fitting guide rods 44131 can be formed. The press-fitting assembly 442 is disposed at the upper ends of the four press-fitting guide rods 44131. When the four press-fitting guide rods 44131 linearly move, they can drive the press-fitting assembly 442 to approach or move away from the pre-assembly port 43421. The press-fitting assembly 442 includes a press-fitting table 4421 and a press-fitting sensing member 4422. The four corners of the press-fitting table 4421 are respectively connected to the upper ends of the four press-fitting guide rods 44131, and the press-fitting table 4421 is parallel to the pre-assembled bottom plate 4341. The press-fitting sensing member 4422 is disposed on the lower surface of the press-fitting table 4421. A screw position 44211 is provided at the middle part of the press-fitting table 4421. The number and position of the screw positions 44211 are the same as the number and position of the fixing components assembled on the stacked group. The screw position 44211 in this embodiment is in the shape of a through hole.Preferably, a locking groove 44212 is further formed in the middle part of the press-fitting table 4421, and the screw position 44211 is formed on the bottom wall of the locking groove 44212. Such a groove structure is provided to facilitate leaving space for the locking operation of the locking assembly 43. The press-fitting table 4421 moves downward and presses on the stacked group, and the threaded end of the fixing part assembled on the stacked group passes through the screw position 44211. At this time, the pressure sensing part 422 senses the pressure of the press-fitting table 4421 on the stacked group. When the pressure value reaches the established press-fitting value, the press-fitting table 4421 stops pressing down and maintains a constant pressure. Then, the feeding and transferring assembly 422 sequentially transfers the flat gasket, spring gasket and nut fed by the locking part feeding assembly 423 to the threaded end of the fixing part. Then, the locking assembly 43 locks the nut, so that the fixing part is fixed to the stacked group. There are two groups of locking assemblies 43 in this embodiment, and the two locking assemblies 43 are respectively arranged oppositely on the upper surface of the press-fitting table 4421. Each locking assembly 43 includes a locking driving part 431 and a locking part 432. The locking driving part 431 is arranged on the upper surface of the press-fitting table 4421, and its output end is connected to the locking part 432. The locking driving part 431 drives the locking part 432 to perform linear movement in the three degrees of freedom directions of XYZ axes respectively, so that the locking part 432 can lock the nut opposite to the threaded end of the fixing part. The locking driving part 431 in this embodiment can adopt an XYZ three-axis linear module, and the locking part 432 can adopt an electric screwdriver. Of course, the X-axis linear module of the locking driving part 431 can also be replaced by a belt transmission method, which is not limited here. The overall operation process of the assembly and fixing device in this embodiment is as follows: When one of the stacking devices 3 finishes stacking at the previous station, the transfer mechanism 45 transfers the fixed loading and carrying mechanism 41 and docks with the stacking device 3. Then, the feeding and transferring assembly 422 feeds the fixing part to the screw bearing position 43211 of the pre-assembly mechanism 43. Then, after the stacked group is transferred between the pre-assembly mechanism 43 and the press-fitting mechanism 44, the press-fitting driving assembly 441 first drives the press-fitting assembly 442 to press down on the stacked group and maintain a constant pressure. Then, the screw bearing position 43211 assembles the fixing part into the stacked group. Then, the feeding and transferring assembly 422 feeds the flat gasket, spring gasket and nut to the threaded end of the fixing part in sequence, and the locking assembly 43 locks the nut again.
