DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] The battery separators that pass the inspection will be wound into rolls and packaged for storage and transportation.

[0031] The rolled battery separator has high density and heavy weight, and needs to be transported by dedicated conveyor lines and pallets. Due to the existence of multiple parallel production lines, the conveyor lines in the production workshop are cross-arranged.

[0032] During the process of conveying battery diaphragms between intersecting conveyor lines, the conveying direction of the battery diaphragms needs to be switched due to the different conveying directions of different production lines. Some small manufacturing companies will set universal ball bearings or lifting structures at the intersection of the conveyor lines to perform reverse conveying of battery diaphragms and pallets. The reverse conveying at this stage requires manual assistance.

[0033] In order to improve the degree of automation of conveyor lines and the efficiency of conveying rolled battery diaphragms, some companies have improved the conveyor lines and designed electric reversing structures at the intersections of different conveyor lines; these reversing structures include but are not limited to: belt-lifting reversing conveying structures, rotating disks with reversing rollers mounted on the surface, reversing push rods and other structures; however, during the reversing process through the above structures, the rolled battery diaphragms need to be conveyed to a predetermined position under the action of inertia or external force, which requires high requirements for the conveying control of rolled battery diaphragms of different sizes and types, requires greater modifications to the conveying production line, and has limited adaptability and efficiency for the reversing conveying of rolled battery diaphragms with larger mass.

[0034] Refer to the attached Figure 1 -Attached Figure 8 A membrane reversing conveying production line includes a first conveying line 600 and a second conveying line 100 arranged crosswise with each other, and also includes a carrying device 400 for carrying a rolled battery separator 300. The carrying device 400 reverses and moves continuously between the first conveying line 600 and the second conveying line 100 to complete the continuous reversing conveying of the rolled battery separator 300.

[0035] A first reversing conveying area 110 is provided on the side of the second conveyor line 100 close to the first conveyor line 600. The carrying device 400 is located in the first reversing conveying area 110 and is conveyed from the surface of the second conveyor line 100 to the surface of the first conveyor line 600. The first reversing conveying area 110 includes a first step conveying roller 111 and a first reversing conveying bottom plate 112. The first reversing conveying bottom plate 112 extends toward the first conveyor line 600. A plurality of self-powered carrying rollers are installed on the surface of the first conveyor line 600. A notch is provided on the side wall of the first conveyor line 600 for the first reversing conveying bottom plate 112 to pass through. The upper end surface of the first reversing conveying bottom plate 112 is lower than the top end surface of the first step conveying roller 111 and the carrying roller. The existence of the first reversing conveying bottom plate 112 will not affect the normal conveying of the carrying device 400.

[0036] Specifically, the carrying device 400 includes a carrying body 410, a receiving groove is opened at the bottom of the carrying body 410, and a retractable automatic power conveying component 430 is arranged in the receiving groove. The automatic power conveying component 430 has an extended state and a retracted state, and the automatic power conveying component 430 is opposite to the first reversing conveying bottom plate 112; it should be noted that the receiving groove and the automatic power conveying component 430 are symmetrically arranged in two groups, and the first reversing conveying bottom plate 112 here is two symmetrically arranged with the automatic power conveying component 430.

[0037] Among them, after the carrying device 400 moves to the first reversing conveying area 110, the automatic power conveying component 430 is controlled to extend and move to the surface of the first conveying line 600 to complete the reversing conveying. In the state of reversing conveying, the automatic power conveying component 430 is controlled to be in an extended state. The extended automatic power conveying component 430 can be tightly pressed against the upper end surface of the first reversing conveying bottom plate 112, so that the carrying device 400 is in a lifted state, that is, the bottom surface of the carrying device 400 is separated from the upper end surface of the first step conveying roller 111; after the carrying device 400 is lifted and is in a stable state, the automatic power conveying component 430 drives the carrying device 400 to move toward the first conveying line 600, and drives the rolled battery diaphragm 300 to move from the upper end of the second conveying line 100 to the upper end of the first conveying line 600, thereby realizing the reversing conveying of the rolled battery diaphragm 300 and meeting the requirements of continuous reversing conveying of the rolled battery diaphragm 300 on the surfaces of different conveying lines.

[0038] After the carrying device 400 is transported to the surface of the first conveyor line 600, the automatic power conveying component 430 is controlled to be in a retracted state. At this time, the automatic power conveying component 430 can be completely retracted into the receiving groove, and the automatic power conveying component 430 will not interfere with the carrying rollers on the surface of the first conveyor line 600. Subsequently, under the power of the carrying rollers on the surface of the first conveyor line 600, the carrying device 400 is continuously transported on the surface of the first conveyor line 600.

[0039] In summary, through the above-mentioned structural design, during the conveying process, the carrying rollers and step rollers on the surface of the second conveyor line 100 are used for conveying, and the conveying process of the carrying device 400 is uniform and stable, and can be transported to the predetermined area without the help of external force and inertia, thereby ensuring the stability of the rolled battery diaphragm 300 during the conveying process; and compared with the traditional belt-lifting reversing conveying structure, reversing push rod, etc., its reversing conveying structure is simpler, the operation process is simple, and the efficiency and stability of the rolled battery diaphragm conveying are greatly improved; and the invention has little improvement on the existing conveyor line, which is convenient for transformation and promotion.

[0040] Please refer to the attached Figure 8Specifically, the automatic power conveying assembly 430 includes a conveying mounting frame 431, at least two automatic power wheels 432 are installed on the side wall of the conveying mounting frame 431, and the automatic power wheels 432 are externally connected to a motor and can rotate automatically. A hydraulic telescopic element 434 is installed between the conveying mounting frame 431 and the accommodating groove. The hydraulic telescopic element 434 is connected to the oil tank through a first pumping pipeline with a built-in pump body. The oil in the oil tank is directionally pumped into the hydraulic telescopic element 434 through the pump body in the first pumping pipeline. After the hydraulic telescopic element 434 is extended, the conveying mounting frame 431 can be pushed up The automatic power wheels 432 are raised to extend and press against the surface of the first reversing conveying bottom plate 112. After the supporting device 400 and the rolled battery separator 300 are stabilized as a whole, the automatic power wheels 432 are controlled to rotate to realize the self-driving control of the supporting device 400. The supporting device 400 moves along the surface of the first reversing conveying bottom plate 112 toward the first conveying line 600 to realize automatic reversing conveying. In the process of contraction, the pump body can be controlled to control the reverse conveying of the control oil to realize the contraction control of the hydraulic telescopic element 434, the conveying mounting frame 431 and other structures.

[0041] Furthermore, a rotating platform 420 is rotatably connected to the upper end of the supporting body 410, and the rolled battery separator 300 is placed on the upper end surface of the rotating platform 420. The rotation direction of the rolled battery separator 300 can be adjusted through the rotating platform 420, and the deflection angle of the rolled battery separator 300 is adjusted according to the angle between the second conveyor line 100 and the first conveyor line 600, so that the axis of the rolled battery separator 300 is perpendicular to the conveying direction, which is convenient for subsequent lifting equipment to be in a constant posture to lift and unload the rolled battery separator 300, ensuring the stable conveying state of the rolled battery separator 300 while improving the efficiency of subsequent lifting and unloading.

[0042] It should be noted here that the battery diaphragm is continuously rolled up on the surface of the cylindrical mold. During the transportation process, the lifting equipment extends into the interior of the cylindrical mold to limit the overall position of the rolled battery diaphragm 300, thereby achieving efficient lifting, unloading and transportation of the rolled battery diaphragm 300.

[0043] Furthermore, a hydraulic rotating element 440 is installed inside the carrying body 410, and the bottom of the rotating platform 420 is connected to the rotating end of the hydraulic rotating element 440 through a connecting shaft 421. The rotation of the rotating platform 420 is controlled by the hydraulic rotating element 440, and the hydraulic rotating element 440 is connected to the hydraulic telescopic element 434 through a second pumping pipeline with a built-in solenoid valve. Through the setting of the above structure, the oil in the hydraulic telescopic element 434 is controlled to enter the hydraulic rotating element 440, so as to realize the rotation control of the hydraulic rotating element 440, and then adjust the deflection angle of the rolled battery diaphragm 300; specifically, after the carrying device 400 is transported to a predetermined position (middle position) on the surface of the first conveying line 600, the control solenoid valve is in a conducting state, and the carrying device 400 automatically contracts the automatic power conveying component 430 under the action of the gravity of the rolled battery diaphragm 300. In this process, the control oil in the hydraulic telescopic element 434 can be squeezed into the hydraulic rotating element 440, and the rotating platform 420 is driven to rotate and control by the hydraulic rotating element 440.

[0044] Through the above-mentioned structural design, the driving control method of the hydraulic rotating element 440 is simplified, and the pressurized control oil in the automatic power conveying component 430 can be utilized. The gravity of the rolled battery diaphragm 300 is cleverly used to drive the rolled battery diaphragm 300 to deflect a predetermined angle. There is no need to specially set up a driving source for rotation control, which simplifies the internal structure of the carrying device 400 and improves its control and reversing transportation efficiency.

[0045] It should also be noted here that when the control oil in the hydraulic telescopic element 434 enters the hydraulic rotating element 440, the control solenoid valve is in a closed state to prevent the oil from flowing in the opposite direction and causing the rolled battery diaphragm 300 to reverse. After the solenoid valve is closed, the remaining control oil in the hydraulic telescopic element 434 is pumped back into the oil tank through the pump body in the first pumping pipeline, thereby achieving complete contraction of the overall structure of the automatic power conveying component 430 and avoiding the impact of the carrier 400 on the surface of the first conveying line 600.

[0046] Furthermore; a first elastic element is built into the hydraulic telescopic element 434, and a second elastic element is sleeved on the outer side of the connecting shaft 421. The first elastic element can be selected as a spring, and the second elastic element is a torsion elastic element 422, which can be selected as a torsion spring; through the design of the first elastic element, the contraction of the hydraulic telescopic element 434 can be accelerated, so that the overall structure of the automatic power conveying component 430 can be more quickly and completely contracted into the receiving groove; through the design of the second elastic element, the oil in the hydraulic rotating element 440 can also be quickly discharged into the oil tank, so as to achieve rapid resetting of the carrying device 400, so as to facilitate the subsequent transfer and transportation of the rolled battery diaphragm 300; through the above-mentioned structural design, the reflux of the oil can be completed by controlling the pump body and the solenoid valve to be in a predetermined state, without manual resetting and adjustment, which further improves the degree of automation of the carrying device 400 and improves the overall reversing transportation efficiency.

[0047] It should be noted that after the carrying device 400 completes the transportation of a single rolled battery diaphragm 300, the solenoid valve is controlled to be in an open state, and at the same time, the pump body is controlled to reversely pump the oil in the hydraulic telescopic element 434 and the hydraulic rotating element 440 into the oil tank, which can realize the reset of the automatic power conveying component 430 and the rotating platform 420, and realize the subsequent repeated and rapid transportation of the rolled battery diaphragm 300.

[0048] An auxiliary lifting device 500 is installed outside the first reversing conveying area 110. The auxiliary lifting device 500 is used to lift the rolled battery diaphragm 300 to a predetermined height and separate it from the carrying device 400. The structural design of the auxiliary lifting device 500 is suitable for rapid reversing conveying of the rolled battery diaphragm 300 with huge mass. Before the automatic power conveying component 430 is extended, the auxiliary lifting device 500 is used to lift the rolled battery diaphragm 300 to a predetermined height to reduce the mass that needs to be overcome during the lifting process of the carrying device 400, thereby achieving rapid lifting of the carrying device 400 and reducing the requirements for the internal pump body and related parts of the carrying device 400. While improving the durability of related parts, the efficiency of reversing conveying of the rolled battery diaphragm 300 is improved.

[0049] Specifically, as a preferred auxiliary lifting device 500, it includes two vertically arranged first electric rails 510 and a first electric slider 511, a second electric rail 520 and a second electric slider 521 are installed between the two first electric sliders 511, and a lifting assembly 530 adapted to the rolled battery separator 300 is fixed to the side wall of the second electric slider 521, and the lifting assembly 530 can be extended into the interior along the axis of the rolled battery separator 300 through the second electric slider 521 to support the rolled battery separator 300, and at the same time, the second electric rails 520 and the rolled battery separator 300 can be lifted through the first electric rails 510 on both sides to achieve rapid lifting of the overall structure of the rolled battery separator 300; the above-mentioned structure has a simple control process. Compared with the traditional electric hoist lifting structure, the structure does not require manual lifting and positioning, and the lifting process of the rolled battery separator 300 is automatically carried out, which further improves the degree of automation and improves the efficiency of the rolled battery separator 300 before reversing transportation.

[0050] A second reversing conveying area 130 is arranged on the side of the second conveyor line 100 away from the first conveyor line 600. The structure of the second reversing conveying area 130 is the same as that of the first reversing conveying area 110. A lifting assembly 200 is installed on the outer side of the second reversing conveying area 130. The lifting assembly 200 can transport the carrying device 400 and the rolled battery separator 300 on the ground to the upper end of the second conveyor line 100, thereby realizing fully automatic loading and transportation of the rolled battery separator 300 in the production workshop without manual adjustment, thereby improving the efficiency of the front-end transportation of the rolled battery separator 300.

[0051] The preferred second reversing conveying area 130 includes a second step conveying roller 131 and a second reversing conveying bottom plate 132. The lifting assembly 200 includes a lifting platform 210 adapted to the second reversing conveying bottom plate 132. A telescopic device 220 is installed at the lower end of the lifting platform 210. After the lifting platform 210 is lifted to the horizontal stage, it can be flush with the second reversing conveying bottom plate 132 to achieve continuous conveying of the carrying device 400. During the conveying process, the lifting platform 210 is first controlled to be in an inclined state, and the automatic power conveying assembly 430 at the bottom of the carrying device 400 is in an extended state. , driving the carrying device 400 and the rolled battery separator 300 to move on the ground. After the carrying device 400 moves to the surface of the lifting platform 210, the telescopic device 220 is controlled to extend, and the lifting platform 210 is adjusted to be in a horizontal state. After the carrying device 400 is lifted to a predetermined height, it is continuously transported on the surface of the second conveyor line 100; after the carrying device 400 is transported to the surface of the second reversing conveying area 130, similarly, the automatic power conveying component 430 is controlled to be in a retracted state, and the carrying device 400 is continuously transported by the carrying rollers on the surface of the second conveyor line 100.

[0052] The above-mentioned reversing conveying method eliminates the need for sinking the floor of the workshop and the need to install a vertical lifting structure in the sunken area, and is suitable for more production workshops that are difficult to renovate.

[0053] A load-bearing conveying area 120 is arranged between the first reversing conveying area 110 and the second reversing conveying area 130. The load-bearing conveying area 120 includes a plurality of load-bearing rollers. The load-bearing rollers and the tops of the step rollers are located on the same horizontal plane to achieve continuous conveyance of the load-bearing device 400. The load-bearing conveying area 120 can also continuously convey the load-bearing device 400, so that the load-bearing device 400 is continuously conveyed on the surface of the second conveyor line 100. The above arrangement can save the power consumption of the load-bearing device 400 and increase the transfer frequency of the load-bearing device 400.

[0056] S1. The carrying device 400 carrying the rolled battery separator 300 is conveyed to the upper end of the first reversing conveying area 110 through the second conveyor line 100. During the conveying process, the carrying rollers and step rollers on the surface of the second conveyor line 100 are used for conveying. The conveying process of the carrying device 400 is uniform and stable without the need for external force and inertia, thereby ensuring the stability of the rolled battery separator 300 during the conveying process.

[0057] S2. After the carrying device 400 is stably located at the upper end of the first reversing conveying area 110, the automatic power conveying assembly 430 is controlled to extend until the carrying device 400 is out of contact with the first step conveying roller 111. During this process, the carrying device 400 and the rolled battery separator 300 are lifted to a predetermined height, preparing for the automatic power conveying assembly 430 to subsequently drive the carrying device 400 to reversing conveyance.

[0058] S3. Control the automatic power conveying component 430 to move along the first reversing conveying bottom plate 112 to a predetermined position on the surface of the first conveyor line 600. After the carrying device 400 is stable, control the automatic power conveying component 430 to retract. Subsequently, the reversing conveying of the rolled battery separator 300 is completed through the first conveyor line 600. During the process of the automatic power conveying component 430 moving directional along the first reversing conveying bottom plate 112 toward the first conveyor line 600, the reversing conveying of the rolled battery separator 300 is completed. Subsequently, the automatic power conveying component 430 is controlled to retract. The carrying device 400 and the rolled battery separator 300 are conveyed again through the automatic power bearing rollers on the surface of the first conveyor line 600, thereby ensuring the efficiency of continuous conveying of the rolled battery separator 300 and the carrying device 400.
