Description

Technical Field

[0001] The invention relates to the field of mechanical equipment manufacturing, and more specifically to an automatically adjustable fuel cell bipolar plate graphite sheet receiving vehicle. Background Art

[0002] The graphite sheet receiving trolley is used to receive graphite sheets. In the production process of graphite sheets, the graphite sheets need to be assembled on the receiving trolley after processing to prevent the graphite sheets from falling directly on the ground. The receiving trolley will then push them to the next production link. Therefore, the graphite sheet receiving trolley plays a very important role and can save time in the entire production process.

[0003] However, the existing graphite sheet receiving cart is relatively simple and can only be adapted to equipment of one specification height, resulting in low utilization rate of the receiving cart and large space occupation. In addition, the existing receiving cart carries a small number of graphite sheets, and the graphite sheets will be worn when entering the receiving table, affecting product quality. Summary of the invention

[0004] The purpose of the present invention is to address the shortcomings of the prior art and provide an automatically adjustable fuel cell bipolar plate graphite sheet receiving vehicle. By setting an adjustment component, the disadvantage that the height of the current receiving vehicle cannot adapt to equipment of different specifications and heights is solved, and the utilization rate of the receiving vehicle is improved. In addition, by setting a lifting component, the load capacity of the receiving platform is increased, the possibility of graphite sheet wear is reduced, and the quality of the graphite sheet is improved.

[0005] The technical solutions of the present invention are as follows:

[0006] An automatically adjustable fuel cell bipolar plate graphite sheet receiving vehicle comprises a frame, a conveyor belt running in the frame and a receiving vehicle cooperating with the conveyor belt, the receiving vehicle comprises a bottom plate, a bearing seat, an adjustment component arranged between the bottom plate and the bearing seat, a receiving platform and a plurality of lifting components arranged between the receiving platform and the bearing seat, the adjustment component is used to adjust the height of the receiving vehicle, and the lifting component is used to adjust the height of the receiving platform under the action of the gravity of the graphite sheet so that the graphite sheet outputted by the conveyor belt each time is translated to the receiving platform in a horizontal posture.

[0007] Preferably, the adjustment assembly comprises a rack arranged between the base plate and the bearing seat, a gear meshing with the rack, and a rocker rotatably arranged in the middle of the gear, and the gear is fixedly arranged on the bearing seat.

[0008] As a preference, a plurality of empty slots are provided on the top of the bearing seat, a plurality of sliding slots are provided at the right ends of the empty slots and a cover plate is slidably arranged in the sliding slot, and a limiting plate is also arranged at the right end of the bearing seat.

[0009] Preferably, the lifting assembly comprises a telescopic rod arranged in the empty slot, a spring sleeved on the telescopic rod, and a connecting plate fixedly connected to the top of the spring.

[0010] As a preference, the frame is further provided with a pushing assembly, which includes a driving cylinder fixedly arranged on the frame, a pushing rod driven by the driving cylinder, and a pushing plate fixedly connected to the pushing rod.

[0011] Preferably, the length of the push plate is at least equal to the thickness of three graphite sheets.

[0012] As a preference, baffles are provided on both sides of the material receiving platform, and the upper ends of the baffles are arranged in an arc shape.

[0013] As a preference, the slide groove is arranged in a "T" shape.

[0014] As another preferred embodiment, a plurality of universal wheels are also provided on the bottom plate.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention is provided with an adjustment component, which can adjust the height of the material receiving trolley by arranging a gear and a rack, rotating the gear and meshing the gear and the rack, so that it can adapt to equipment of different heights, thereby realizing the universality and interchangeability of the material receiving trolley, improving the utilization rate and compatibility of the material receiving trolley, and reducing the cost of production equipment.

[0017] 2. The present invention is provided with a lifting assembly, and a telescopic rod and a spring are provided to enable the receiving platform to descend under the action of the gravity of the graphite sheet. Since the specifications and weight of the graphite sheets of the same batch are consistent, according to the principle of Hooke's law, after the receiving platform is lowered, the thickness of the graphite sheet can be inferred according to the compression amount of the spring, and thus the weight of the graphite sheet can be inferred. The weight of the graphite sheet is equal to the elastic force of the spring, and thus the spring with a matching elastic coefficient is selected by adjusting the elastic force to make the receiving height of the receiving platform consistent with the height of the conveyor belt after each discharge, thereby increasing the carrying capacity of the receiving vehicle. In addition, since the graphite sheet has a certain flexibility, it will bend when entering the receiving platform. This method can also reduce the possibility of wear of the graphite sheet and improve product quality.

[0018] 3. The present invention is also provided with a pushing assembly and a baffle. By arranging the pushing plate to cooperate with the limit plate on the supporting plate, the graphite sheets are kept flush on both sides in the longitudinal direction, and when three graphite sheets are piled up, the graphite sheets are pushed together, thereby reducing the working time of the cylinder and extending the service life of the cylinder. In addition, by arranging the baffle, the graphite sheets are kept flush on both sides in the width direction, thereby avoiding the possibility of the graphite sheets falling out of the receiving vehicle during the discharging process and improving the neatness of the graphite sheets.

[0019] In summary, the present invention has functions such as adjustable height of the material receiving cart and adjustable elasticity, and is suitable for the field of mechanical equipment manufacturing. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings.

[0029] Embodiment 1

[0030] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0031] As Figures 1 to 7 shown, an automatically adjustable material receiving cart for fuel cell bipolar plate graphite sheets includes a frame 1, a conveyor belt 11 running inside the frame 1, and a material receiving cart 2 cooperating with the conveyor belt 11. The material receiving cart 2 includes a bottom plate 21, a bearing seat 22, an adjustment assembly 3 provided between the bottom plate 21 and the bearing seat 22, a receiving table 23, and a plurality of lifting assemblies 4 provided between the receiving table 23 and the bearing seat 22. The adjustment assembly 3 is used to adjust the height of the material receiving cart 2, and the lifting assembly 4 is used to adjust the height of the receiving table 23 under the gravity of the graphite sheet 6 so that each graphite sheet 6 output by the conveyor belt 11 is translated to the receiving table 23 in a horizontal posture.

[0032] like Figure 1 and Figure 2 As shown, the adjustment assembly 3 includes a rack 31 disposed between the base plate 21 and the bearing seat 22 , a gear 32 meshing with the rack 31 , and a rocker 33 rotatably disposed in the middle of the gear 32 , and the gear 32 is fixedly disposed on the bearing seat 22 .

[0033] It is worth mentioning that the present invention is provided with an adjustment component 3. By setting a gear 32 and a rack 31, after the gear 32 is rotated, the height of the material receiving trolley 2 is adjusted under the meshing of the gear 32 and the rack 31, so that it can adapt to equipment of different heights, thereby realizing the universality and interchangeability of the material receiving trolley 2, improving the utilization rate of the material receiving trolley 2 and the compatibility of the material receiving trolley 2, and reducing the cost of production equipment.

[0034] like Figure 3 As shown, a plurality of slots 24 are formed on the top of the bearing seat 22 , a slide slot 25 is formed at the right end of the plurality of slots 24 , a cover plate 26 is slidably disposed in the slide slot 25 , and a limit plate 27 is also disposed at the right end of the bearing seat 22 .

[0035] like Figure 3 As shown, the lifting assembly 4 includes a telescopic rod 41 arranged in the empty slot 24 , a spring 42 sleeved on the telescopic rod 41 , and a connecting plate 43 fixedly connected to the top of the spring 42 .

[0036] It should be further explained that the present invention is provided with a lifting component 4. The present invention is provided with a lifting component 4. By arranging a telescopic rod 41 and a spring 42, the receiving platform 23 is lowered under the gravity of the graphite sheet 6. Since the specifications and weights of the graphite sheets 6 of the same batch are consistent, according to the principle of Hooke's law, after the receiving platform 23 is lowered, the thickness of the graphite sheet 6 can be inferred according to the compression amount of the spring 42, and the weight of the graphite sheet 6 can be inferred. The weight of the graphite sheet 6 is equal to the elastic force of the spring 42. Therefore, by adjusting the elastic force and selecting a spring 42 with a matching elastic coefficient, the receiving height of the receiving platform 23 after each discharge is consistent with the height of the conveyor belt 11, thereby increasing the carrying capacity of the receiving vehicle 2. In addition, since the graphite sheet 6 has a certain flexibility, there will be a problem of bending when entering the receiving platform 23. This method can also reduce the possibility of wear of the graphite sheet 6 and improve product quality.

[0037] like Figure 4 As shown, a pushing assembly 5 is also provided on the frame 1 , and the pushing assembly 5 includes a driving cylinder 51 fixedly arranged on the frame 1 , a pushing rod 52 driven by the driving cylinder 51 , and a pushing plate 53 fixedly connected to the pushing rod 52 .

[0038] like Figure 4 As shown, the length of the push plate 53 is at least equal to the thickness of three graphite sheets 6.

[0039] As Figure 1 shown, baffles 28 are provided on both sides of the material receiving table 23.

[0040] In addition, the present invention is also provided with a pushing component 5 and a baffle 28. By setting the top pushing plate 5 to cooperate with the limiting plate 27 on the bearing seat 22, the graphite sheets 6 are kept flush on both sides in the longitudinal direction, and when the graphite sheets 6 are stacked to three pieces, the graphite sheets 6 are pushed together, reducing the working duration of the air cylinder 51 and prolonging the service life of the air cylinder 51. In addition, by setting the baffle 28, the graphite sheets 6 are kept flush on both sides in the width direction, avoiding the possibility of the graphite sheets 6 falling out of the material receiving cart 2 during the discharging process and improving the neatness of the graphite sheets 6.

[0041] As Figure 3 shown, the sliding groove 25 is set in a "T" shape to play a role of limiting and sliding.

[0042] As Figure 1 shown, a plurality of universal wheels 7 are further provided on the bottom plate 21, which is convenient for workers to push away the material receiving cart 2 when it is full, making it convenient and labor-saving.

[0043] Embodiment 2

[0044] As Figure 3 shown, the same or corresponding components as those in Embodiment 1 are adopted with the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below; the difference between this Embodiment 2 and Embodiment 1 is that the upper end of the baffle 28 is set to be arc-shaped.

[0045] In this embodiment, by setting the upper end of the baffle 28 to be arc-shaped, it is convenient for the graphite sheets 6 to enter the material receiving table 23 more smoothly.

[0046] Working process

[0047] First, adjust the material receiving cart 2 to the height suitable for the equipment. Then, transfer the graphite sheet 6 from the conveyor belt 11 to the material receiving table 23. Under the gravity of the graphite sheet 6, the material receiving table 23 descends. The worker selects springs 42 with different elastic coefficients according to the weight of the graphite sheet 6. At this time, the worker needs to slide the cover plate 26 covering the empty slot 24 to the right to eject the telescopic rod 41 and the spring 42. By selecting springs 42 with different elastic coefficients, the material receiving table 23 rises when the next graphite sheet 6 is transferred, and the material receiving height of the material receiving table 23 is at the same height as the conveyor table 11, so as to ensure that the material receiving height is consistent with the height of the conveyor belt 11 after each discharge. When the material receiving table 23 is filled with graphite sheets 6 and descends to the lowest height, the lifting assembly 4 retracts into the empty slot 24. The worker slides the cover plate 26 to the left to cover the connecting plate 26. After receiving the material, the worker moves the material receiving cart 2 away for discharging, completing the whole process. Similarly, when the specification of the graphite sheet 6 changes, the material receiving height can also be made consistent with the height of the conveyor belt 11 after each discharge by selecting springs 42 with different elastic coefficients.

[0048] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "front and back", "left and right", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0049] Certainly, in this technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation on the quantity.

[0050] The above is only the preferred embodiment of the present invention in combination with the drawings, but the present invention is not limited to the above embodiment. It should be noted that for those skilled in the art, without departing from the structure of the present invention, various deformations and improvements can be made, which should also be regarded as the protection scope of the present invention and will not affect the implementation effect and practicality of the present invention.
