Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, specifically to a fully automated sorting mechanism for medium and large density electrode plates. Background Technology

[0002] Medium-density plates refer to a type of plate in lead-acid batteries. In the production process of lead-acid batteries, the coated and dried plates need to be automatically stacked and palletized by a sorting mechanism.

[0003] The existing fully automatic sorting mechanism for medium and large density electrode plates includes a transfer mechanism and a stacking mechanism. The transfer mechanism transfers the electrode sheets on the feed belt to the feeding point of the stacking mechanism, thereby stacking the electrode sheets into piles.

[0004] However, in actual use, when the fully automatic sorting mechanism of Zhongda dense electrode plates malfunctions, such as when the stacking mechanism jams, the transfer mechanism will continue to feed material towards the stacking mechanism. Even if the transfer mechanism is stopped, the electrode sheets on the feeding belt will still accumulate and scatter on the transfer mechanism, which can easily lead to an increase in the amount of scrapped electrode sheets. Therefore, in order to deal with the above problems, we have adopted a new technical solution to address the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic sorting mechanism for medium and large density electrode plates to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The fully automatic sorting mechanism for Zhongda dense electrode plates includes a support frame near the feeding point of the stacking mechanism. The support frame is equipped with a conveyor belt assembly and a receiving box. One end of the frame of the conveyor belt assembly is rotatably connected to the support frame via a shaft column. The conveyor belt assembly and the support frame are connected by a support component. The support component has a first support position that aligns the conveyor belt assembly with the feeding point of the stacking mechanism, and a second support position that aligns the conveyor belt assembly with the receiving box.

[0008] Preferably, a drive assembly is also installed on the support frame. The drive assembly includes a toothed roller that is rotatably mounted to the support frame. An internal toothed ring is coaxially fixed on the toothed roller. A connecting gear set that is connected to the redirecting shaft of the conveyor belt assembly is installed at the other end of the frame of the conveyor belt assembly.

[0009] Preferably, the connecting gear set includes a first gear disk coaxially fixed to a redirecting shaft at one end of the conveyor belt assembly, a second gear disk meshing with the bottom of the first gear disk, and the second gear disk being rotatably connected to the frame of the conveyor belt assembly via a shaft.

[0010] Preferably, the centerline of the shaft column coincides with the centerline of the redirecting shaft at one end of the conveyor belt assembly frame.

[0011] Preferably, the support assembly includes a telescopic cylinder fixed to the bottom of the support frame, a crossbeam rod is movably mounted on the output shaft of the telescopic cylinder, and a sliding groove is provided on the frame of the conveyor belt assembly for the crossbeam rod to slide and adapt.

[0012] Preferably, the support frame includes a base plate, on which two side support plates are fixed respectively on both sides of the conveyor belt assembly, and the receiving box is located on the base plate between the two side support plates.

[0013] Preferably, the receiving box includes a long frame box body, and a cushioning foam pad is fixed on the inner wall surface of the long frame box body.

[0014] Preferably, the roller shaft of the toothed roller extends out of the side of the support frame, and a drive motor that is connected to the roller shaft of the toothed roller is fixed on the support frame.

[0015] Preferably, the internal gear ring disc includes a connecting disc coaxially fixed to the gear roller, and an internal gear ring is fixed on the surface of the connecting disc.

[0016] Preferably, a gap is formed between the inner toothed ring and the roller surface of the toothed roller. The support assembly is connected to the gear set and the inner ring tooth surface of the inner toothed ring disk for transmission engagement in the first support position. The support assembly is connected to the gear set and the roller surface of the toothed roller for transmission engagement in the second support position.

[0017] In the above technical solution, the fully automatic sorting mechanism for medium and large density electrode plates provided by the present invention adds a receiving box and connects the conveyor belt assembly to the support frame rotatably through the shaft column. Then, by switching the support position of the support assembly, the corresponding position of the discharge end of the conveyor belt assembly is changed. For example, under normal conditions, the discharge position of the conveyor belt assembly is aligned with the feeding position of the stacking mechanism. When the stacking mechanism or the subsequent production line station of the stacking mechanism fails, the discharge position of the conveyor belt assembly is aligned with the receiving box, so that the receiving box can temporarily receive the electrode plates, thereby reducing the amount of scrapped electrode plates when the production line fails.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Medium-to-large density electrode plates refer to a type of electrode plate in lead-acid batteries. The "medium-to-large density" in "medium-to-large density electrode plate" usually refers to the battery's capacity level and application scenario, i.e., medium-to-large, high-density lead-acid batteries. In the lead-acid battery production process, the coated and dried electrode plates need to be automatically stacked by a sorting mechanism, with each stack containing 18-25 plates. Then, a corresponding handling robot loads the stacked electrode plates into the battery box. Existing fully automated sorting mechanisms for medium-to-large density electrode plates include a transfer mechanism and a stacking mechanism. The transfer mechanism's conveying speed is greater than the feed belt's conveying speed, resulting in a larger spacing between the electrode plates on the transfer mechanism. This serves to accelerate the electrode plate processing and increase the spacing between the electrode plates. The transfer mechanism... The electrode sheets on the feed strip are transferred to the feeding point of the stacking mechanism, which facilitates the stacking mechanism to stack the electrode sheets into piles. However, in actual use, we found that when the fully automatic sorting mechanism for medium-density electrode plates malfunctions, such as when the stacking mechanism jams, the transfer mechanism will still receive the electrode sheets from the feed strip and continue to feed them rapidly toward the stacking mechanism. Even if the transfer mechanism is stopped, the electrode sheets on the feed strip will still accumulate and scatter on the transfer mechanism, which can easily cause electrode plate deformation and peeling off of the dry coating on the electrode plates, thus increasing the amount of scrapped electrode sheets. In addition, since the feed strip connects the entire production line, the feed strip cannot be stopped arbitrarily. Therefore, in order to address the above problems and reduce the amount of scrapped electrode sheets, we have adopted a new technical solution to address these issues.

[0029] Please see Figures 1-6 The fully automatic sorting mechanism for medium and large density plates provided in this embodiment of the invention includes a support frame 1 near the feeding point of the stacking mechanism. The support frame 1 is provided with a conveyor belt assembly 2 and a receiving box 6. One end of the frame of the conveyor belt assembly 2 is rotatably connected to the support frame 1 through a shaft column 4. The conveyor belt assembly 2 and the support frame 1 are connected through a support assembly 5. The support assembly 5 has a first support position that aligns the conveyor belt assembly 2 with the feeding point of the stacking mechanism, and the support assembly 5 also has a second support position that aligns the conveyor belt assembly 2 with the receiving box 6.

[0030] Specifically, when the support component 5 is in the first position, the receiving end of the conveyor belt component 2 is aligned with the feeding belt, and the discharge end of the conveyor belt component 2 is aligned with the feeding point of the stacking mechanism. When the fully automatic sorting mechanism for the dense electrode plates malfunctions, the support component 5 switches from the first support position to the second support position. At this time, the conveyor belt component 2 can deflect downward around the shaft column 4 under the drive of the support component 5, so that the discharge end of the conveyor belt component 2 is transferred from the feeding point of the stacking mechanism to the position aligned with the receiving box 6. Thus, the receiving box 6 can temporarily receive the electrode plates, thereby reducing the amount of scrapped electrode plates when the production line malfunctions.

[0031] It should be noted that the extension and retraction state of the support component 5 can be triggered by manual control or by the corresponding sensor control mechanism. The specific triggering principle and method are existing technologies. In addition, the conveyor belt component 2 has the same structure as the existing conveyor belt. The conveyor belt component 2 mainly includes a frame and redirecting shafts rotatably installed at both ends of the frame. Multiple idlers located between the two redirecting shafts are rotatably installed in the frame. The frame is equipped with an annular conveyor belt that is driven and sleeved on the two redirecting shafts. These details will not be elaborated further.

[0032] In another embodiment of the present invention, a drive assembly 3 is also installed on the support frame 1. The drive assembly 3 provides driving force for the forward conveying of the conveyor belt assembly 2. The forward conveying of the conveyor belt assembly 2 refers to the movement of the electrode plate above the conveyor belt assembly 2 in a direction away from the feeding belt. The drive assembly 3 includes a toothed roller 3.1 rotatably mounted on the support frame 1. The axis of the toothed roller 3.1 is parallel to the axis of the reversing roller of the conveyor belt assembly 2. The toothed roller 3.1 is located below the conveyor belt assembly 2. An inner toothed ring disk 3.2 is coaxially fixed on the toothed roller 3.1. The inner toothed ring disk 3.2 includes a connecting disk 3.21 coaxially fixed on the toothed roller 3.1. An inner toothed ring 3.22 is fixed on the disk surface of the connecting disk 3.21. The inner toothed ring 3.22 forms the inner ring toothed surface of the inner toothed ring disk 3.2. An interval space is formed between the inner toothed ring 3.22 and the roller surface of the toothed roller 3.1.

[0033] The other end of the frame of the conveyor belt assembly 2 is equipped with a connecting gear set 3.3 that is connected to the redirection shaft of the conveyor belt assembly 2. The connecting gear set 3.3 is located in the interval space. In the first support position, the connecting gear set 3.3 is engaged with the inner ring tooth surface of the internal toothed disc 3.2. In the second support position, the connecting gear set 3.3 is engaged with the roller surface of the toothed roller 3.1. The roller shaft of the toothed roller 3.1 extends out of the side of the support frame 1. A drive motor that is connected to the roller shaft of the toothed roller 3.1 is fixed on the support frame 1.

[0034] In actual use, the drive motor drives the toothed roller 3.1 to rotate on the support frame 1, thereby driving the coaxially fixed inner ring toothed disk 3.2 to rotate synchronously. Since the support assembly 5 is connected to the gear set 3.3 and the inner ring tooth surface of the inner toothed disk 3.2 for transmission and meshing in the first support position, and the support assembly 5 is connected to the gear set 3.3 and the roller surface of the toothed roller 3.1 for transmission and meshing in the second support position, when the support assembly 5 switches from the first support position to the second support position, the conveyor belt assembly 2 can still receive the power transmission from the drive assembly 3. That is to say, if the position of the drive assembly 3 does not change, the power transmission provided by the drive assembly 3 will not be interrupted due to the change in the position of the conveyor belt assembly 2.

[0035] In addition, the radius of the inner ring toothed disc 3.2 is larger than the radius of the toothed roller 3.1. Therefore, the linear velocity of the inner ring toothed disc 3.2 is greater than the linear velocity of the toothed roller 3.1. Thus, when the support assembly 5 switches from the first support position to the second support position, the conveying speed of the conveyor belt assembly 2 in the second position is less than the conveying speed in the first position, thereby reducing the speed of the conveyor belt assembly 2 when feeding material toward the receiving box 6.

[0036] In other words, when the support component 5 is in the first support position, the conveying speed V1 of the transfer mechanism is greater than the conveying speed V_su of the feeding belt. Therefore, the interval between each electrode plate on the transfer mechanism is larger, which plays the role of speeding up the electrode and expanding the spacing between each electrode, thus making it easier for the stacking mechanism to stack the electrode into a stack.

[0037] When the support component 5 is in the second support position, the conveying speed V2 of the transfer mechanism is less than the conveying speed Vsu of the feeding belt. At this time, the interval between each electrode plate on the transfer mechanism is reduced, and a stepped overlapping state with the ends connected appears between each electrode plate. In this way, on the one hand, the electrode plates are pre-stacked on the conveyor belt of the transfer mechanism, which is beneficial for the electrode plates to be in a neat state when the receiving box 6 is received. On the other hand, while keeping the capacity of the receiving box 6 unchanged, the time for the receiving box 6 to be filled with electrode plates is extended, which is beneficial for reducing the emptying frequency of the receiving box 6 per unit time.

[0038] In another embodiment of the present invention, the connecting gear set 3.3 includes a first gear disk 3.31 coaxially fixed to the redirection shaft at one end of the conveyor belt assembly 2. A second gear disk 3.32 is engaged with the bottom of the first gear disk 3.31. The second gear disk 3.32 is rotatably connected to the frame of the conveyor belt assembly 2 through a shaft 3.33. The axis of the shaft 3.33 is parallel to the axis of the redirection shaft of the conveyor belt assembly 2. The support assembly 5 is in the first support position, at which time the inner ring gear disk 3.2 engages with the first gear disk 3.31 to provide driving force for the forward conveying of the conveyor belt assembly 2. The support assembly 5 is in the second support position, at which time the roller surface of the toothed roller 3.1 engages with the second gear disk 3.32, and the second gear disk 3.32 engages with the first gear disk 3.31 to provide driving force for the forward conveying of the conveyor belt assembly 2. Therefore, the conveying direction of the conveyor belt of the conveyor belt assembly 2 is forward in both the first support position and the second support position.

[0039] In another embodiment of the present invention, the centerline of the shaft post 4 coincides with the centerline of the redirection shaft at one end of the frame of the conveyor belt assembly 2, thereby ensuring that the receiving end of the conveyor belt assembly 2 and the feeding belt are always in a relatively aligned state during the deflection process, so as to properly receive the electrode sheets on the feeding belt.

[0040] In another embodiment of the present invention, the support assembly 5 includes a telescopic cylinder 5.1 fixed to the bottom of the support frame 1, a crossbeam rod 5.2 is movably mounted on the output shaft of the telescopic cylinder 5.1, and a sliding groove 5.3 is provided on the frame of the conveyor belt assembly 2 for the crossbeam rod 5.2 to slide and adapt.

[0041] The telescopic cylinder 5.1 can be a linear retraction drive device, such as a hydraulic cylinder, a telescopic air cylinder, an air spring, or a straight rod motor. The first support position and the second support position correspond to the maximum extension point and the maximum retraction point of the telescopic cylinder 5.1's telescopic stroke. The axis of the crossbeam 5.2 is perpendicular to the stroke direction line of the telescopic cylinder 5.1, and the axis of the crossbeam 5.2 is parallel to the axis of the redirecting roller of the conveyor belt assembly 2. When the telescopic cylinder 5.1 drives the conveyor belt assembly 2 to deflect around the shaft column 4, the crossbeam 5.2 can slide accordingly in the chute 5.3 to ensure that the conveyor belt assembly 2 can deflect normally.

[0042] In another embodiment of the present invention, the support frame 1 includes a base plate 1.1, on which two side support plates 1.2 are fixed respectively on both sides of the conveyor belt assembly 2. The receiving box 6 is located on the base plate 1.1 between the two side support plates. With the support of the side support plates 1.2, an active space is formed between the conveyor belt assembly 2 and the ground, and the conveyor belt assembly 2 can be on the same conveying line as the stacking mechanism feed point and the feeding belt.

[0043] In another embodiment of the present invention, the receiving box 6 includes a long frame box body 6.1, and a cushioning foam pad 6.2 is fixed on the inner wall surface of the long frame box body 6.1. The long frame box body 6.1 is a top-opening box, and the cushioning foam pad 6.2 plays the role of cushioning and supporting the electrode sheet.

[0044] In another embodiment of the present invention, a through-hole 7 is provided on the side of the frame of the conveyor belt assembly 2, and a connecting channel 8 is provided inside the frame of the conveyor belt assembly 2. The through-hole 7 and the slide groove 5.3 are both on the connecting channel 8. A connecting plate 9 is movably disposed in the connecting channel 8. A notch 10 is provided on the connecting plate 9, which is aligned and communicating with the through-hole 7. A right-angled trapezoidal opening is provided on the connecting plate 9, which is connected to the slide groove 5.3, as shown in the attached drawings of the specification. Figure 6 As shown, an extension groove is provided on the hypotenuse of the right-angled trapezoidal opening. The groove wall on one side of the extension groove is flush with the fixed edge line of the right-angled trapezoidal opening. A relief opening is provided on the bottom edge line of the right-angled trapezoidal opening. The right-angled trapezoidal opening, the relief opening, and the extension groove constitute a connecting joint 15 that is connected to the slide 5.3. The corners of the joint 15 are ABCDEFG in sequence, and the edge line of the joint 15 is formed by connecting the lines ABCDEFG in sequence.

[0045] A pin tube 11 is inserted into the through-hole 7. The pin tube 11 has a threaded part 12 on the outside. The inner contour surface of the cross-section of the pin tube 11 is rectangular. A square rod 13 is adapted to be inserted into the pin tube 11. One end of the square rod 13 is fixed coaxially with the end of the idler of the conveyor belt assembly 2. A limiting hole 14 is opened on the side of the side support plate 1.2, which is aligned with the through-hole 7. The idler of the conveyor belt assembly 2 can rotate synchronously with the conveyor belt of the conveyor belt assembly 2.

[0046] In actual use, the support component 5 is in the first support position, with one end of the pin tube 11 located in the through hole 7 and the other end of the pin tube 11 located in the limiting hole 14, thereby working with the telescopic cylinder 5.1 to support and limit the conveyor belt assembly 2, and improve the stability of the conveyor belt assembly 2.

[0047] When the support assembly 5 is in the first support position, the crossbeam 5.2 is in contact with the edge of the EF segment of the assembly port 15. When the support assembly 5 switches from the first support position to the second support position, the crossbeam 5.2 disengages from the edge of the EF segment of the assembly port 15 and moves toward the edge of the AG segment of the assembly port 15. During the approach, the crossbeam 5.2 contacts and is squeezed with the BC inclined section of the assembly port 15. Under the squeezing force of the crossbeam 5.2, the connecting plate 9 slides forward along the length of the connecting channel 8, while the crossbeam 5.2 slides relative to the BC segment of the assembly port 15 until the crossbeam 5.2 disengages from the BC inclined section of the assembly port 15. At this time, the forward sliding of the connecting plate 9 also reaches the end position. At this time, the groove wall of the notch 10 engages with the threaded part 12 outside the pin tube 11.

[0048] Since the idler rollers of the conveyor belt assembly 2 can rotate synchronously with the conveyor belt of the conveyor belt assembly 2, the pin tube 11 can be driven by the conveyor belt of the conveyor belt assembly 2 to rotate under the connecting transmission action of the square rod 13. When the rotating pin tube 11 is adapted to engage with the groove wall of the notch 10 through the threaded part 12, the pin tube 11 can undergo axial helical displacement under the helical force, thereby causing the pin tube 11 to disengage from the limiting port 14, thereby releasing the pin tube 11 from supporting and limiting the conveyor belt assembly 2, so that the conveyor belt assembly 2 can deflect downward.

[0049] The speed at which the conveyor belt assembly 2 deflects downward is greater than the moving speed of the crossbeam 5.2 within the splicing opening 15, thereby causing the crossbeam 5.2 to re-contact the edge of the EF segment of the splicing opening 15. At this time, the conveyor belt assembly 2 is supported by the support assembly 5 and deflects synchronously as the support assembly 5 descends, until the support assembly 5 reaches the second support position.

[0050] In other words, when the support component 5 is in the first support position, the conveyor belt assembly 2 is also in the corresponding first support position. The conveyor belt assembly 2 can normally transport the electrode sheet on the feed belt to the feed point of the stacking mechanism at a speed of V1. At this time, the conveyor belt assembly 2 is limited and supported by the three points of the shaft column 4, the support component 5 in the first support position, and the pin tube 11. The pin tube 11 is supported in such a way that one end is located in the frame of the conveyor belt assembly 2, and the other end is located in the limiting port 14 on the side support plate 1.2 of the support frame 1.

[0051] During the transition from the first support position to the second support position, the telescopic cylinder 5.1 of the support assembly 5 first drives the crossbeam 5.2 to move downward within the assembly opening 15. At this time, the conveyor belt assembly 2 is limited and supported by the shaft column 4 and the pin tube 11. When the crossbeam 5.2 pushes the connecting plate 9 to make the threaded part 12 fit and engage with the groove wall of the notch 10, the pin tube 11 disengages from the limiting opening 14. At this time, the conveyor belt assembly 2 is limited and supported by the shaft column 4. Under the action of gravity, the conveyor belt assembly 2 deflects downward around the shaft column 4. The downward deflection speed of the conveyor belt assembly 2 around the shaft column 4 is greater than the downward movement speed of the crossbeam 5.2 driven by the telescopic cylinder 5.1 within the assembly opening 15. Thus, the telescopic cylinder 5.1 finally moves downward through the crossbeam 5.2. The conveyor belt assembly 2 is resupported, that is, the crossbeam 5.2 is restored to contact with the edge of the EF segment of the splice port 15. At this time, the conveyor belt assembly 2 is limited and supported by the shaft column 4 and the support assembly 5. As the support assembly 5 continues to move towards the second support position, the conveyor belt assembly 2 moves synchronously with the support assembly 5 under the action of gravity until the support assembly 5 reaches the second support position. At this time, the conveyor belt assembly 2 is driven by the toothed roller 3.1 through the connecting gear set 3.3.

[0052] It should be noted that when the crossbeam 5.2 returns to contact with the edge of the EF segment of the assembly port 15, the conveyor belt assembly 2 tilts at an angle as the support assembly 5 moves toward the second support position. As a result, the crossbeam 5.2 slides from the EF segment of the assembly port 15 toward the FG segment of the assembly port 15, causing the connecting plate 9 to slide in the opposite direction along the length of the connecting channel 8 under the squeezing force of the crossbeam 5.2, thereby causing the threaded part 12 to separate from the groove wall of the notch 10.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
