[0001] The utility model relates to the technical field of lead-acid battery plate production equipment, in particular to a pre-stacking mechanism and plate stacking equipment. Background Art

[0002] The production process of lead-acid battery plates mainly includes the following steps: coating a continuous lead strip with paste and then covering it with paste paper to obtain a continuous plate, cutting the continuous plate to obtain a single plate, stacking the single plates to obtain plate piles, and introducing the plate piles into a heating device for curing and drying.

[0003] First, the existing stacking method to keep the single plate in a flat state is: use a conveyor belt to continuously output to the stacking mechanism, and the output method is mainly to pick up and place with a suction cup. The defect of the above method is that the working surface of the conveyor belt is flat to keep the wet plate flat. The grid is prone to slippage and displacement on the working surface of the conveyor belt, and the grid in the high-speed conveying state cannot adjust its position in time, which leads to poor neatness of the side of the plate, and it is necessary to adapt to add a stacking mechanism;

[0004] Second, after the proximity switch detects that the plate is transported to the predetermined position, the suction cup drive drives the suction cup to adsorb the plate to complete the pick-up and placement of a single plate. The stacking speed is limited by the response speed of the proximity switch, the speed of the suction cup to pick up and place the plate, etc., and the stacking efficiency is low. Based on the length of continuous plates, the fastest stacking speed of the existing method is 30 to 40 m / min. Utility Model Content

[0013] A preferred technical solution is that the push member includes an arc portion, and the push surface includes an arc push area located in the arc portion; the arc portion is arranged between the feeding mechanism and the discharging conveyor belt along the circumferential direction of the side surface of the roller body.

[0014] A preferred technical solution is that the first tidying component includes a first driving member connected to the pushing member and driving the pushing member to reciprocate along the axial direction of the roller body.

[0015] A preferred technical solution is that the push member is an elastic sheet-shaped push member.

[0038] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0039] In the description of the present application, it should be noted that, unless otherwise specified, “plurality” means more than two; the terms “upper”, “lower”, “left”, “right”, “inside”, “outside”, etc., indicating directions or positional relationships, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0040] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0041] If the width direction of the plates in the existing sorting and discharging conveyor belt is relative to the side, since there is no infinite structure on both sides of the conveying direction of the plates, the sorting mechanism will cause the plates to move along the conveying direction, including but not limited to the displacement of the plates to partial overlap, thereby affecting the normal overlap of the plates, and the feasibility is poor. Example

[0042] like Figure 1-5 As shown, the pre-stacking mechanism of the embodiment includes a lamination roller 1, a feeding mechanism 2 and a discharge conveyor belt 3, the lamination roller 1 includes a rotatably arranged roller body 101, and a plurality of supporting and limiting members 102 arranged circumferentially and spaced apart from each other on the side of the roller body 101; the feeding mechanism 2 is arranged on the feeding side of the lamination roller 1, and the feeding mechanism 2 is configured to feed at least two electrode plates between adjacent supporting and limiting members 102; the working surface of the discharge conveyor belt 3 is arranged on the horizontal discharge side of the central axis of the roller body 101, and the feeding end of the discharge conveyor belt 3 is extended between the vertical direction positive projections of the supporting and limiting members 102 and / or to the side in the width direction.

[0043] The support and limiter 102 divides the space around the lamination roller into several lamination spaces. Preferably, the support and limiter 102 is arranged to extend radially along the lamination roller 1. The number of polar plates fed into a single lamination space is more than two, and may be three, four, five or even more.

[0044] The lamination roller 1 has a relative feed side and a discharge side. It can be understood that the electrode plate is guided by the feed mechanism 2 to the supporting limit member 102 in a load-bearing state; the supporting limit member 102 has a first end close to the central axis of the roller body 101 and a second end away from the central axis of the roller body 101. The top surface of the first end must be equal to or lower than the second end and the supporting limit member 102 is located on the side of the central axis of the roller body 101, and the supporting limit member 102 is in a load-bearing state; on the contrary, if the top surface of the first end of the supporting limit member 102 is higher than the top surface of the second end, the electrode plate placed on the supporting limit member 102 will fall due to its own weight.

[0045] The supporting and limiting member 102 is used to support the electrode plate or the electrode plate stack and to limit the displacement range of the electrode plate or the electrode plate stack along the circumferential direction of the side surface of the roller body during the rotation of the lamination roller 1 .

[0046] It can be understood that, taking the feeding mechanism 2, the lamination roller 1 and the discharge conveyor belt 3 arranged in sequence from left to right as an example, the lamination roller 1 rotates clockwise, and the electrode plates between adjacent supporting limiters 102 follow the supporting limiters 102 and are sequentially transferred from the left side and the top of the lamination roller 1 to the right side of the lamination roller 1. In the above conveying process, at least two electrode plates between adjacent supporting limiters 102 are arranged due to their own weight, and the plate thickness side of the electrode plate close to the roller body 101 abuts against the side of the roller body 101, and the side faces of the discharge electrode plate stack opposite to each other along the conveying direction of the discharge conveyor belt 3 are neat.

[0047] like Figure 1-4 As shown, in some preferred embodiments, the feeding mechanism 2 includes a feeding conveyor belt 201, and the discharge end of the feeding conveyor belt 201 is higher than the central axis of the roller body 101, so that the feeding conveyor belt 201 can discharge more than two electrode plates to between adjacent supporting limit members 102.

[0048] The conveying direction of the feed conveyor belt 201 and the rotation direction of the lamination roller 1 are as follows: Figure 4 As indicated by the arrow.

[0049] Optionally, the feed end of the feed conveyor belt 201 is higher, lower or flush with the discharge end. When the feed end is flush with the discharge end, the conveying direction of the feed conveyor belt 201 is horizontal. When the feed end is higher than the discharge end, the conveying direction of the feed conveyor belt 201 is inclined downward. When the feed end is lower than the discharge end, the conveying direction of the feed conveyor belt 201 is inclined upward.

[0050] In the process of forming the plate stack, the collision between the plates will inevitably cause the wet lead paste at the cutting edge to deform. Compared with horizontal conveying and inclined upward conveying, inclined upward high-speed conveying is conducive to reducing the probability of the subsequent plate colliding with the previous plate during the landing process, thereby reducing the probability of the landing process affecting the deformation of the subsequent plate, which is conducive to improving the coating quality of the cutting edge of the subsequent plate and the coating quality of the collision position of the previous plate surface. Therefore, further, the feeding end of the feeding conveyor belt 201 is lower than the discharging end.

[0051] like Figure 3 , 4 As shown, in some preferred embodiments, the feeding mechanism 2 also includes an acceleration mechanism, which is arranged between the feeding end of the feeding conveyor belt 201 and the lamination roller 1, and the conveying speed of the acceleration mechanism along the conveying direction of the feeding conveyor belt 201 is greater than the conveying speed of the feeding conveyor belt 201.

[0052] The electrode plate needs to overcome the dynamic friction of the supporting limiter 102 when it falls to the support limiter 102. The conveying speed of the feed conveyor belt 201 is limited by the slippage of the electrode plate on the feed conveyor belt 201, and the deadweight of a single electrode plate is small, so the inertia of the electrode plate output by the feed conveyor belt 201 is limited. The additional acceleration mechanism applies a force to the electrode plate toward the lamination roller 1, so that the electrode plate that is completely or partially separated from the feed conveyor belt 201 has greater kinetic energy toward the roller body 101, so as to overcome the dynamic friction with the supporting limiter 102, thereby making the electrode plate fall to a position closer to the side of the roller body 101, reducing the influence of the displacement of the electrode plate on the deformation of the lead paste on the cutting side during the rotation of the roller. The acceleration mechanism includes but is not limited to a conveyor belt and an acceleration roller 202.

[0053] like Figure 5 As shown, in some preferred embodiments, the pre-stacking mechanism includes a first arranging component 4, which is disposed on both axial sides of the roller body supporting the limiting member 102, and has a blocking surface 4a for blocking the side of the electrode plate.

[0054] The electrode plates in the lamination roller 1 have first side surfaces that are opposite to each other along the axial direction of the roller body. The first arranging assembly 4 is used to arrange the combined surfaces of the first side surfaces of at least two electrode plates.

[0055] During the rotation of the lamination roller 1, the position of the electrode plate is limited by the adjacent support limiter 102 and the push surface 4a. During the sorting process, the electrode plate does not move in the conveying direction of the discharge conveyor belt 3, that is, the addition of the lamination roller 1 makes the sorting of the first side of the electrode plate feasible.

[0056] like Figure 5As shown, in some preferred embodiments, the push member 401 includes an arc portion 4011, and the push surface 4a includes an arc push area 4a1 located at the arc portion 4011; the arc portion 4011 is arranged along the side circumferential direction of the roller body 101 between the feeding mechanism 2 and the discharge conveyor belt 3.

[0057] As the lamination roller 1 rotates continuously, the pole plate continuously adjusts its own position due to position change and deadweight. When adjusting the position, the pole plates of the pole plate stack abut against the push surface 4a respectively, and are guided to the predetermined first side position through the push surface 4a to achieve the first side arrangement. Compared with the push surface 4a partially set on the radial side of the roller body 101, the annular arc push area 4a1 is conducive to increasing the path length of the pole plate to be arranged and pushed when the lamination roller 1 is turned over, and optimizing the arrangement effect of the pole plate position along the axial direction of the roller body.

[0058] like Figure 5 As shown, in some preferred embodiments, the first sorting assembly 4 includes a first driving member 402 connected to the push member 401 and driving the push member 401 to reciprocate along the axial direction of the roller body 101. The first driving member 402 is used to adjust the position of the push surface 4a to adapt to the pre-stack of different-sized plates. In addition, compared with the guiding effect of the fixed push surface 4a, the position of the push member 401 along the axial direction of the roller body is slightly adjusted while the lamination roller 1 rotates, driving the push member 401 to relatively beat the first side surface, which is conducive to further optimizing the sorting effect of the position of the plate along the axial direction of the roller body.

[0059] In some preferred embodiments, the push member 401 is an elastic sheet push member. Compared with the rigid push member 401, the elastic sheet push member has a predetermined deformation amplitude, which is beneficial to reduce the deformation effect of the push member 401 on the lead paste on the first side of the plate, and improve the qualified rate of the plate. In addition, based on the annular arc push block area 4a1 and the extended plate sorting path, the elastic sheet push member can achieve a predetermined first side sorting effect.

[0060] The elastic sheet-like push-off member includes but is not limited to a plastic sheet, a foam sheet, etc., so as to reduce the push-off damage to the electrode plate caused by the push-off surface 4a.

[0061] like Figure 5 As shown, in some preferred embodiments, the push member 401 includes an extension portion 4012 located radially outside the arc portion 4011, and the push surface 4a includes an extended push area 4a2 located in the extension portion 4012; the extension portion 4012 is located directly above the top of the roller surface of the roller body 101, and the push surface 4a is extended on both sides of the extension portion 4012.

[0062] Compared with only the first side of the arc portion 4011 pushing the electrode plate, the extended pushing zone 4a2 of the extended portion 4012 and the combined pushing surface of the top of the arc portion 4011 are arranged on both sides of the axial direction of the roller body of the electrode plate, and the pushing area with the first side of the electrode plate is larger. When the stacking roller 1 is positioned above the roller body 101, the displacement and flipping amplitude of the electrode plate is larger, and the larger pushing area is more conducive to adjusting the axial position of the roller body of the electrode plate.

[0063] Furthermore, the end of the extension portion 4012 away from the arc portion 4011 is fixedly connected to the first driving member 402 or the frame. Based on the elastic sheet-like push-stop member 401, the extension portion 4012 is closer to the fixed connection end, and its deformable amplitude is smaller than the arc portion 4011. In the path where the electrode plate in the stacking roller 1 rises from the feed side to the top of the roller body 101 and then descends to the discharge side, the deformable amplitude of the push-stop member has a trend of gradually increasing first and then gradually decreasing. The combined push-stop surface of the extension portion 4012 extending the push-stop area 4a2 and the top of the arc portion 4011 is beneficial to further optimize the guiding effect of the electrode plate.

[0064] Furthermore, the push-stop member 401 including the extension portion 4012 and the arc portion 4011 is suspended, and one end of the extension portion 4012 away from the arc portion 4011 is suspended and connected to the frame.

[0065] The extension portion 4012 has a predetermined width, and the central angle corresponding to the extension portion 4012 is not less than the central angle corresponding to a sector-shaped receiving space. Furthermore, the length of the extension portion 4012 along the radial direction of the roller body is greater than the length of the electrode plate.

[0066] like Figure 3 As shown, in some preferred embodiments, the supporting and limiting member 102 includes a comb-tooth member, and the comb teeth of the comb-tooth member in the same supporting member are arranged at intervals along the axial direction of the roller body 101. The number of comb teeth of the comb-tooth member is more than two, and in this embodiment, there are three comb teeth, which is conducive to improving the bearing stability and limiting performance of the electrode plate.

[0067] In this embodiment, the discharge conveyor belt 3 is composed of four unit conveyor belts, and the four unit conveyor belts and three comb teeth are alternately arranged along the axial direction of the roller body.

[0068] As an alternative, the supporting and limiting member is a single supporting member with a continuous bearing surface, and the discharge conveyor belts 3 are correspondingly arranged on both sides of the single supporting member.

[0069] In this embodiment, the feed conveyor belt 201 and the discharge conveyor belt 3 are both conveyor chains, and the conveyor chains are driven by sprockets. The length of the feed conveyor belt 201 is controlled to be as short as possible, which is conducive to improving the position stability of the electrode plate on the working surface of the feed conveyor belt 201.

[0070] like Figure 3 , 4As shown, in some preferred embodiments, the feed end of the feed conveyor belt 201 is lower than the discharge end; the feed conveyor belt 201 includes a first supporting member 2011, and the first supporting member 2011 is supported and arranged below the working surface of the feed conveyor belt 201. The conveying direction of the feed conveyor belt 201 is inclined upward, and the first supporting member 2011 is conducive to improving the flatness of the working surface of the feed conveyor belt 201, and improving the position stability of the plate during high-speed conveying on its working surface.

[0071] like Figure 4 As shown, in some preferred embodiments, the working surface of the discharge conveyor belt 3 is horizontally arranged, and the discharge conveyor belt 3 includes a second supporting member 301, and the second supporting member 301 is supported and arranged below the working surface of at least the feed end of the discharge conveyor belt 3.

[0072] In this embodiment, the second supporting member 301 is only supported and arranged below at least the working surface of the feed end of the discharge conveyor belt 3. The second supporting member 301 is conducive to improving the flatness of the feed end of the discharge conveyor belt 3, and is conducive to ensuring that the electrode stack transferred to the discharge conveyor belt 3 maintains its roller main body axial position in the lamination roller 1.

[0073] The second supporting member 301 is only arranged below the working surface of the feed end, or the second supporting member 301 is extended and arranged below the entire working surface of the discharge conveyor belt 3. Compared with a single-piece electrode plate, the position stability of the electrode plate stack on the working surface of the discharge conveyor belt 3 is higher. Therefore, the preferred second supporting member 301 is only arranged below the working surface of the feed end, which is conducive to simplifying the equipment structure.

[0074] like Figure 6 , 7 As shown, the plate stacking equipment of the embodiment includes the above-mentioned pre-stacking mechanism and the stacking mechanism 5, and the stacking mechanism 5 includes a lifting stacking platform 501 arranged on the discharge side of the pre-stacking mechanism.

[0075] The conveying speeds of the plate slitting device, the feeding conveyor belt 201, the lamination roller 1, and the discharging conveyor belt 3 are improved as a whole, that is, the stacking efficiency of the plate stacking equipment is improved.

[0076] like Figure 7 As shown, in some preferred embodiments, the stacking mechanism 5 includes a second sorting component 502, and the second sorting component 502 is configured to push the discharge electrode plate and / or lift the electrode plate stack above the stacking platform 501 along the discharge direction.

[0077] In this embodiment, the conveying direction of the discharge conveyor belt is the first direction, and the opposite direction of the first direction is the second direction. The second sorting component 502 includes a baffle 5021 and a push member 5022, the baffle 5021 and the push member 5022 are arranged opposite to each other along the first direction, the push member 5022 is arranged on the side of the lifting and stacking platform 501 in the second direction, the baffle 5021 is arranged on the side of the lifting and stacking platform 501 in the first direction, the push member 5022 is connected to the second driving member, and the second driving member 5023 drives the push member 5022 to reciprocate along the first direction.

[0078] Based on the first arranging component 4 and the second arranging component 502 of the pre-stacking device, the alignment of the two groups of opposite sides in the plate stack is achieved, and the side of the plate stack is highly neat. Based on the first arranging component 4 of the pre-stacking device, the stacking mechanism 5 does not need to be provided with an arranging component in the width direction of the discharge conveyor belt, which facilitates the side arrangement of more than two groups of discharge conveyor belts and the corresponding stacking mechanism 5 and the feed conveyor belt 201, and more than two groups of supporting limit members 102 are provided in the axial direction of the roller body 101.

[0079] The plate collecting method is based on the above-mentioned plate stacking equipment, and includes the following steps:

[0080] S1: feeding at least two electrode plates into the space between adjacent supporting and limiting members 102 in the lamination roller 1;

[0081] S2: The stacking roller 1 rotates continuously, and the discharge conveyor belt 3 receives the stack of plates between the support limiters 102 and inertially guides the stacked plates to the lifting and stacking platform 501 .

[0082] Furthermore, S2: the stacking roller 1 continuously rotates while adjusting the position of the electrode plate along the axial direction of the roller body, and then the discharge conveyor belt 3 receives the electrode plate stack between the supporting limit members 102 and inertially guides it to the lifting and stacking platform 501.

[0083] The specific working process of the plate stacking equipment includes the following steps:

[0084] S1, the lamination roller 1 rotates continuously, the feeding conveyor belt 201 continuously conveys the electrode plates, and the electrode plates are discharged piece by piece at the discharge end of the feeding conveyor belt 201, and after being accelerated by the acceleration roller 202, the electrode plates fall above the supporting and limiting members 102, and two or more electrode plates are introduced into adjacent supporting and limiting members 102;

[0085] S2, the electrode plate turns over as the lamination roller 1 rotates, and a single electrode plate turned over or multiple electrode plates turned over at the same time abut against the push surface 4a, and the electrode plate is guided to a predetermined position along the axial direction of the roller body;

[0086] S3, when the blocking plate follows the rotation of the lamination roller 1 and turns to the discharge side, the discharge conveyor belt 3 receives the plate stack above the support limiter 102, and the discharge conveyor belt 3 continuously outputs the plate stack;

[0087] S4, the electrode plates are stacked on the discharge end of the discharge conveyor belt 3 and are inertially led to the lifting and stacking platform 501 on the discharge side, and the electrode plates are stacked on the lifting and stacking platform 501.

[0088] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
