[0028] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment.
[0029] Embodiment 1
[0030] Referring to Figures 1 to 5 For the first embodiment of the present application, the embodiment provides a power battery structure composite pole cleaning and passivation device, comprising,
[0031] The cleaning mechanism 100 comprises a treatment box 101 for cleaning and passivating the composite pole, a water inlet pipe 102 fixedly installed outside the treatment box 101, and a drain pipe 103 fixedly installed at the bottom of the treatment box 101;
[0032] The bearing mechanism 200 comprises a horizontal plate 201, an adjusting assembly 202 arranged below the horizontal plate 201 for placing the composite pole for cleaning, and a driving assembly 203 arranged at the top of the horizontal plate 201 for driving the adjusting assembly 202 to adjust the height;
[0033] And the guide mechanism 300 cooperates with the bearing mechanism 200 to automatically discharge the cleaned composite pole;
[0034] The adjusting assembly 202 comprises a box 202a, a bearing net plate 202b fixedly installed in the inner cavity of the box 202a, and a rotating rod 202c hinged at the top of the box 202a.
[0035] Among them, the cleaning mechanism 100 realizes efficient cleaning and passivation treatment of the composite pole through the synergistic effect of the treatment box 101, the water inlet pipe 102 and the drain pipe 103. The treatment box 101 as the core container can accommodate cleaning liquid and passivation liquid, and realize the circulation and replacement of liquid through the water inlet pipe 102 and the drain pipe 103, to ensure the continuity and stability of the cleaning and passivation process.
[0036] Specifically, the adjusting assembly 202 further comprises a connecting plate 202d fixedly installed outside the rotating rod 202c, a cross rod 202e hingedly installed at a groove of the connecting plate 202d, a positioning plate 202f fixedly installed outside the cross rod 202e, and an ejector 202g arranged at the top of the box 202a and used to push one side of the box 202a to adjust the angle.
[0037] The box 202a and the bearing net plate 202b in the adjusting assembly 202 provide a stable bearing platform for the composite pole, avoid direct sinking and stacking, and ensure that each composite pole can fully contact the cleaning liquid and the passivation liquid. The design of the rotating rod 202c and the ejector 202g enables the box 202a to adjust the angle, facilitates the placement and removal of the composite pole, and avoids the sliding or deviation of the composite pole during processing.
[0038] Further, the ejector 202g comprises a shaft seat 202g-1 fixedly installed at the top of the box 202a, a shaft rod 202g-2 rotatably installed in the inner cavity of the shaft seat 202g-1, a limiting sleeve 202g-3 movably sleeved outside the shaft rod 202g-2, and an electric push rod 202g-4 fixedly installed at the top of the limiting sleeve 202g-3.
[0039] The electric push rod 202g-4 in the ejector 202g cooperates with the shaft rod 202g-2 and the limiting sleeve 202g-3 to accurately adjust the angle of the box 202a. When the electric push rod 202g-4 is extended, it pushes the box 202a to rotate downward on one side around the rotating rod 202c, so that the box 202a as a whole presents a left-high and right-low state, thereby enabling the composite pole to roll downward after processing.
[0040] Preferably, the driving assembly 203 comprises a top plate 203a fixedly installed at the top of the processing box 101, a gas cylinder 203b fixedly installed at the top of the top plate 203a, and a limiting piece 203c arranged outside the cross plate 201 and used to vertically guide the height adjustment of the adjusting assembly 202.
[0041] The driving assembly 203 cooperates with the top plate 203a, the gas cylinder 203b and the limiting piece 203c to adjust the height of the adjusting assembly 202, so that the composite pole can be completely immersed in the liquid while being vertically guided, thereby avoiding affecting the processing effect due to improper height, and the driving assembly 203 can also move the adjusting assembly 202 and the material guiding mechanism 300 up and down in the liquid, thereby further improving the processing effect of the cleaning and passivation liquids.
[0042] Further, the limiting member 203c includes a rack plate 203c-1 fixedly installed in the inner cavity of the processing box 101, a gear 203c-2 engaged with the rack plate 203c-1, a connecting block 203c-3 fixedly installed on the top of the horizontal plate 201, and a connecting rod 203c-4 rotatably installed in the inner cavity of the connecting block 203c-3, the end of the connecting rod 203c-4 being fixedly connected with the outer side of the gear 203c-2.
[0043] The engagement design of the rack plate 203c-1 and the gear 203c-2 in the limiting member 203c ensures the stability and accuracy of the adjusting assembly 202 during height adjustment, and the design of the connecting block 203c-3 and the connecting rod 203c-4 further enhances the stability and reliability of the structure, ensuring that the driving assembly 203 can still maintain high efficiency in long-term operation.
[0044] Further, the cleaning mechanism 100 further comprises a liquid adding pump 104 fixedly installed on the outer side of the processing box 101, and a water injection bucket 105 fixedly installed on the processing box 101 for temporary water addition.
[0045] The introduction of the liquid adding pump 104 ensures the supply efficiency of the passivation liquid, and the water injection bucket 105 provides the convenience of temporary water addition, avoiding the interruption of the process due to insufficient liquid.
[0046] In use, first, the composite pole is placed on the bearing net plate 202b of the tray 202a, and the driving assembly 203 adjusts the adjusting assembly 202 to the appropriate height through the cooperation of the air cylinder 203b and the limiting member 203c, so that the pole is completely immersed in the cleaning liquid or passivation liquid in the processing box 101.
[0047] During the cleaning and passivation process, the liquid adding pump 104 and the water injection bucket 105 ensure the continuous supply and concentration stability of the liquid; after the processing is completed, the electric push rod 202g-4 of the ejector 202g pushes the tray 202a to tilt around the rotating rod 202c, so that the pole is smoothly rolled into the inclined box 307 under the guidance of the partition plate 302, and the automatic discharge is completed; the reset spring 305 ensures the quick reset of the partition plate 302, preparing for the processing of the next batch of poles.
[0048] In summary, through the cooperation of the cleaning mechanism 100, the bearing mechanism 200 and the material guiding mechanism 300, the efficient cleaning, passivation and automatic discharge functions of the composite pole are realized.
[0049] The cleaning mechanism 100 ensures the uniform distribution and continuous supply of the cleaning and passivation liquid through the circulation design of the processing box 101, the water inlet pipe 102 and the drain pipe 103.
[0050] The bearing mechanism 200 solves the problems of easy accumulation and difficult extraction of the composite pole by adjusting the cooperation of the adjusting assembly 202 and the driving assembly 203, and ensures that the pole is completely immersed in the liquid.
[0051] The material guiding mechanism 300 realizes the stable discharge of the pole by the inclined design of the box 202a and the guiding effect of the partition plate 302, and avoids collision or damage.
[0052] Embodiment 2
[0053] Referring to Figure 3 and Figure 4 The second embodiment of the utility model is different from the previous embodiment, and the material guiding mechanism 300 for slowing down the speed of the composite pole when the box 202a is inclined is provided.
[0054] Specifically, the material guiding mechanism 300 comprises a movable rod 301 hinged to the outside of the box 202a, a partition plate 302 fixedly installed on the outside of the movable rod 301 and used for blocking or guiding the falling of the composite pole, a bearing block 303 fixedly installed on the outside of the partition plate 302, a telescopic rod 304 hinged to the outside of the bearing block 303, a reset spring 305 movably sleeved on the outside of the telescopic rod 304 and used for pushing out the partition plate 302 at the inclined angle, a fixed seat 306 fixedly installed on the end of the reset spring 305, and an inclined box 307 fixedly installed on the outside of the partition plate 302 and used for guiding the falling of the composite pole.
[0055] Further, the partition plate 302 can be flexibly adjusted in position according to the inclined angle, blocks or guides the falling of the pole, the design of the reset spring 305 and the telescopic rod 304 ensures that the partition plate 302 can be quickly reset and kept stable, and the inclined box 307 further guides the orderly falling of the pole, ensures the stability and safety of the material guiding process, and improves the practicability and reliability of the overall device.
[0056] In use, when the box 202a is inclined, the movable rod 301 drives the partition plate 302 to adjust the position, blocks or guides the falling of the composite pole, and at the same time, the bearing block 303 and the telescopic rod 304 cooperate to make the partition plate 302 move flexibly according to the inclined angle; the reset spring 305 provides elastic support during the movement of the partition plate 302, ensures that it can be quickly reset and kept stable, and the inclined box 307 further guides the orderly falling of the pole, avoids collision or damage caused by rapid falling, thereby realizing the smooth transition and safe discharge of the composite pole in the material guiding process.
[0057] In summary, the material guiding mechanism 300 effectively slows down the falling speed of the composite pole after the box 202a is inclined, and avoids the collision or damage caused by the rapid falling of the pole.
