DETAILED DESCRIPTION

[0024] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0028] Please refer to Figure 1 , Figure 1 It is a schematic diagram of the structure of the storage device 1 in the embodiment of the present invention. As shown in the figure, the storage device 1 of the present application includes a storage mechanism 11 and a rotary switching mechanism 12. The rotary switching mechanism 12 is arranged on the ground, and the rotary switching mechanism 12 is located on the moving path of the storage mechanism 11. In specific application, the storage cavity 1111 of the storage mechanism 11 stores two rows of workpieces placed side by side. The storage mechanism 11 is pushed to a predetermined position. At this time, the storage mechanism 11 is aligned with the rotary switching mechanism 12, and a row of workpieces in the storage cavity 1111 faces the loading mechanism. The loading mechanism takes out a row of workpieces in the storage cavity 1111 one by one for loading. After all the workpieces in the storage cavity 1111 are loaded, the rotary switching mechanism 12 drives the storage mechanism 11 to rotate 180 degrees, so that another row of workpieces in the storage cavity 1111 faces the loading mechanism, and the loading mechanism can continue to grab the workpieces for loading. In this embodiment, the workpieces are bipolar plates.

[0029] Refer to Figure 2 and Figure 3 , Figure 2 Schematic diagram of the structure of the material storage mechanism 11 in the embodiment of the present invention; Figure 3It is a partial schematic diagram of the material storage mechanism 11 in the embodiment of the present invention. As shown in the figure, the material storage mechanism 11 includes a material storage rack 111, a first material storage plate 112 and a second material storage plate 113. The material storage rack 111 has a material storage cavity 1111, and the first material storage plate 112 and the second material storage plate 113 are arranged opposite to each other on the material storage rack 111 and are located in the material storage cavity 1111. The surfaces opposite to the first material storage plate 112 and the second material storage plate 113 are provided with a plurality of grooves 1121, and the workpieces are arranged in sequence in the plurality of grooves 1121. In this embodiment, the number of the first material storage plate 112 and the second material storage plate 113 are both two. The use of two first material storage plates 112 and two second material storage plates 113 can store more workpieces. Of course, the number of the first material storage plate 112 and the second material storage plate 113 can be adaptively increased or decreased according to actual needs. The above is only one embodiment of the present invention and should not be limited thereto.

[0030] Refer to Figure 4 , Figure 4 1 is a schematic diagram of the structure of the first material storage plate 112 in an embodiment of the present invention. As shown in the figure, a clamping handle 114 is provided on the material storage rack 111. The clamping handle 114 includes a clamping rod 1141, a driving rod 1142 and an elastic member 1143. One end of the clamping rod 1141 is rotatably arranged on the first material storage plate 112 through a bearing seat, the other end of the clamping rod 1141 has an inclined surface 11411, the driving rod 1142 is connected to the clamping rod 1141, and the elastic member 1143 is sleeved on the clamping rod 1141. One end of the elastic member 1143 abuts against the bearing seat, and the other end of the elastic member 1143 abuts against the driving rod 1142. The elastic member 1143 is a spring.

[0031] When the material storage mechanism 11 is filled with materials for transportation, the inclined surface 11411 of the clamping rod 1141 faces upward, and the clamping rod 1141 acts on the upper surface of the lifting block 1122 of the first material storage plate 112, so that the lifting block 1122 and the baffle 1131 arranged on the second material storage plate 113 can realize the lateral limitation of the workpiece to avoid material falling due to uneven ground or obstacles. After the material storage mechanism 11 reaches the predetermined position, the driving rod 1142 is rotated so that the inclined surface 11411 of the clamping rod 1141 moves downward and pulls the lifting block 1122 upward. The inclined surface 11411 moves inward under the force. At this time, the elastic member 1143 is compressed. When the lifting block 1122 is lifted to the predetermined position, the clamping rod 1141 corresponds to the lifting slot 11221, and the compressed elastic member 1143 restores to the uncompressed state. The elastic force of the elastic member 1143 pushes the driving rod 1142 and thereby pushes the clamping rod 1141 to move in the direction of the lifting slot 11221. The end of the clamping rod 1141 with the inclined surface 11411 is inserted into the lifting slot 11221 to support the lifting block 1122. One side of the workpiece loses the obstruction of the lifting block 1122, so that the loading mechanism can take out the workpiece and load it along the groove 1121.

[0032] In specific applications, the material storage mechanism 11 has a position adjustment plate 115. The position adjustment plate 115 is slidably arranged on the material storage rack 111, and can be fixed to the material storage rack 111 by adjusting the hand wheel. The first material storage plate 112 is arranged on the position adjustment plate 115. The position of the first material storage plate 112 can be changed by adjusting the position of the position adjustment plate 11. When the position adjustment plate 115 moves toward the direction of approaching the second material storage plate 113, the distance between the first material storage plate 112 and the second material storage plate 113 becomes smaller. When the position adjustment plate 115 moves away from the second material storage plate 113, the distance between the first material storage plate 112 and the second material storage plate 113 becomes larger. The position adjustment plate 115 is adjusted according to workpieces of different sizes to change the distance between the first material storage plate 112 and the second material storage plate 113, so as to realize compatible material storage for workpieces of different specifications.

[0033] In specific application, a limiting column 1123 is inserted into the lifting block 1122. The limiting column 1123 is slidably arranged on the fixing block 1113 on the first material storage plate 112. When the lifting block 1122 is pulled upward to prepare for loading, the limiting column 1123 slides along the fixed block 1113 to guide the lifting block 1122. When loading is completed or transportation is required, the driving rod 1142 is toggled to drive the clamping rod 1141 to be pulled out of the lifting slot 11221. The lifting block 1122 slides toward the second material storage plate 113 under the action of gravity. Since the diameter of the limiting column 1123 inserted at one end of the lifting block 1122 is smaller than the diameter of the limiting column 1123 away from the end of the lifting block 1122, the downward movement distance of the lifting block 1122 is limited to achieve positioning. After the lifting block 1122 moves down to its position, the clamping rod 1141 extends out and acts on the upper surface of the lifting block 1122 again to prevent the lifting block 1122 from moving upward during the movement, so that the lifting block 1122 and the baffle 1131 cooperate again to limit the workpiece and prevent material from being thrown off during transportation. Figure 5 and Figure 6 , Figure 5 Schematic diagram of the structure of the rotary switching mechanism 12 in an embodiment of the present invention; Figure 6It is a schematic diagram of the structure of the rotating component 121 in the embodiment of the present invention. As shown in the figure, the rotary switching mechanism 12 includes a rotating component 121 and a lifting component 122. Further, the rotating component 121 includes a mounting seat 1211, a rotating shaft 1212, a rotating plate 1213, a rotating gear 1214, a rack 1215 and a rotating driving member 1216. The rotating shaft 1212 is rotatably arranged on the mounting seat 1211. The rotating plate 1213 is connected to one end of the rotating shaft 1212. The rotating gear 1214 is sleeved on the rotating shaft 1212. The rack 1215 is slidably arranged on the mounting seat 1211 through a guide rail slider, and the rack 1215 is meshed with the rotating gear 1214. The rotating driving member 1216 is arranged on the mounting seat 1211, and the output end of the rotating driving member 1216 is connected to the rack 1215, and the rotating driving member 1216 is a cylinder. Furthermore, the lifting assembly 122 includes a lifting drive member 1221 and a lifting column 1222. The lifting drive member 1221 is disposed on the rotating plate 1213, and the lifting drive member 1221 is a cylinder. The lifting column 1222 is disposed at the output end of the lifting drive member 1221, and the lifting column 1222 is movably connected to the storage rack 111. In this embodiment, the number of the lifting drive members 1221 is four, and correspondingly, the number of the lifting columns 1222 is also four, and the four lifting drive members 1221 are disposed at the four corners of the rotating plate 1213. Of course, the number of the lifting drive members 1221 and the lifting columns 1222 can be adaptively increased or decreased according to actual needs. The above is only one embodiment of the present invention and should not be limited thereto.

[0034] After the storage mechanism 11 is in place, the jacking drive member 1221 drives the jacking column 1222 to move toward the jacking plate 1114 of the storage rack 111. The jacking plate 1114 has a positioning hole 11141 that matches the shape of the jacking column 1222. The jacking column 1222 is inserted into the positioning hole 11141, and the storage rack 111 leaves the ground under the action of the jacking assembly 122. Then, the rotating drive member 1216 drives the rack 1215 to move, and the rack 1215 drives the rotating gear 1214 to rotate, and the rotating gear 1214 drives the rotating shaft 1212 to rotate, thereby driving the rotating plate 1213 to rotate, and the rotating plate 1213 drives the storage rack 111 to rotate 180 degrees, so as to realize the switching of the two rows of workpieces on the storage mechanism 11.

[0035] Preferably, the rotating assembly 121 further includes a supporting wheel 1217. The supporting wheel 1217 is disposed on the mounting seat 1211 through a supporting frame, and the supporting wheel 1217 abuts against the lower surface of the rotating plate 1213. In this embodiment, there are four supporting wheels 1217, and the four supporting wheels 1217 support the rotating plate 1213 so that the rotating plate 1213 can be driven to rotate smoothly. Of course, the number of supporting wheels 1217 can be adaptively increased or decreased according to actual needs. The above is only one embodiment of the present invention and should not be limited thereto.

[0036] Preferably, the rotation switching mechanism 12 also includes an auxiliary rotation assembly 123. The auxiliary rotation assembly 123 includes an auxiliary rotation driving member 1231 and an auxiliary rotating shaft 1232. The auxiliary rotation driving member 1231 is arranged on the outer cover of the storage mechanism 11 through a fixed plate, and the auxiliary rotation driving member 1231 is a cylinder. One end of the auxiliary rotating shaft 1232 is connected to the output end of the auxiliary rotation driving member 1231, and the other end of the auxiliary rotating shaft 1232 is movably connected to the storage rack 111. Before the rotating assembly 121 drives the storage rack 111 to rotate, the auxiliary rotation driving member 1231 drives the auxiliary rotating shaft 1232 to move, and the other end of the auxiliary rotating shaft 1232 is inserted into the rotating shaft hole at the top of the storage rack 111, so as to ensure the rotation center and rotation stability of the storage rack 111 when rotating.

[0037] In order to ensure that the storage mechanism 11 is accurately aligned with the rotation switching mechanism 12, the rotation switching mechanism 12 of the present application further includes a positioning assembly 124. The positioning assembly 124 includes a positioning block 1241 and a proximity switch 1242, and the positioning block 1241 and the proximity switch 1242 are both arranged on the rotating plate 1213. When the storage mechanism 11 moves toward the rotation switching mechanism 12, the positioning block 1241 blocks the storage rack 111, that is, when the storage mechanism 11 moves into position, the storage rack 111 just abuts against the positioning block 1241, and the proximity switch 1242 senses the storage rack 111 during the movement of the storage mechanism 11. After the proximity switch 1242 senses the storage rack 111, it feeds back a signal to the control system of the storage device 1, and the control system of the storage device 1 controls the lifting assembly 122 to lift, thereby ensuring accurate lifting. In this embodiment, the rotation switching mechanism 12 may not be provided with the positioning assembly 124. When the positioning assembly 124 is not provided, the mounting seat 1211 is directly fixed to the ground through the supporting feet and the anchor bolts.

[0038] In order to ensure that the storage mechanism 11 accurately moves to the predetermined position, the storage device 1 of the present application further includes a guide limit mechanism 13. Figure 7 , Figure 7 1 is a schematic diagram of the structure of the material storage mechanism 11 and the guide and limit mechanism 13 in the embodiment of the present invention. As shown in the figure, the guide and limit mechanism 13 includes a first guide and limit assembly 131 and a second guide and limit assembly 132.

[0039] The first guide limit assembly 131 includes a U-shaped guide groove 1311, a first guide drive 1312 and a locking column 1313. The U-shaped guide groove 1311 is arranged on the outer cover of the storage mechanism 11. The first guide drive 1312 is arranged on the storage rack 111, and the first guide drive 1312 is a cylinder. The locking column 1313 is connected to the output end of the first guide drive 1312. In specific application, the top of the storage rack 111 has a column 1314. When the storage rack 111 is moved, the column 1314 moves along the U-shaped guide groove 1311. The diameter of the column 1314 matches the groove width of the U-shaped guide groove 1311. When the column 1314 moves to the innermost end of the U-shaped guide groove 1311,

[0040] The first guide drive member 1312 drives the locking column 1313 to extend, and the locking column 1313 is inserted into the locking hole 131111 of the locking block 13111 on the U-shaped guide groove 1311, thereby limiting the column 1314, thereby limiting the storage rack 111 to prevent it from moving. In addition, the column 1314 replaces the auxiliary rotating component 123 to play an auxiliary rotation role. The auxiliary rotating component 123 is omitted while fully ensuring the rotation center and rotation stability of the storage rack 111 during rotation, reducing assembly steps and saving production costs.

[0041] The second guide limiter assembly 132 includes two guide plates 1321 arranged opposite to each other, a front limiter 1322 and a rear limiter 1323. A guide groove 13211 is formed between the two guide plates 1321, and the width of the guide groove 13211 matches the width of the moving wheel 110 of the storage mechanism 11, so that the moving wheel 110 of the storage mechanism 11 moves along the length direction of the guide groove 13211. Preferably, a blocking block 132111 is provided at one end of the guide groove 13211, and the blocking block 132111 blocks the moving wheel 110 to prevent it from rolling out of the guide groove 13211. The front limiter 1322 includes a front stop cylinder 13221 and a front stop rod 13222. The front stop cylinder 13221 is arranged on one side of the guide plate 1321 by installing a vertical plate, and the front stop rod 13222 is connected to the output end of the front stop cylinder 13221. The rear limiter 1323 includes a rear limiter cylinder 13231 and a rear limiter plate 13232. The rear limiter plate 13232 is slidably arranged by a guide rail slider, and the rear limiter plate 13232 is connected to the output end of the rear limiter cylinder 13231. In specific application, the material storage rack 111 is pushed along the guide groove 13211, and when the rear wheel abuts against the blocking block 132111, the front stop cylinder 13221 drives the front gear rod 13222 to extend, and then the rear limiter cylinder 13231 drives the rear limiter plate 13232 to move toward the material storage rack 111, and the rear limiter plate 13232 pushes the material storage rack 111 to abut against the front gear rod 13222, and the front limiter 1322 and the rear limiter 1323 realize the limiting of the material storage rack 111 to prevent it from moving.

[0042] In specific applications, the above-mentioned rotation switching mechanism 12 and the guide limiting mechanism 13 are electrically connected to the control system of the storage device 1, and the control system of the storage device 1 controls the rotation switching mechanism 12 and the guide limiting mechanism 13 to actuate, so as to achieve the effect of automatic control of the storage device 1. Of course, the control system of the storage device 1 can be any one of an industrial computer, a PLC or a single-chip microcomputer, which will not be described in detail here.

The switching is convenient, and the labor intensity of workers is effectively reduced. Moreover, the stored workpieces can be fixed during the movement of the material storage mechanism to avoid the occurrence of material falling.
