Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery plate production equipment, in particular to a continuous plate conveying and sorting mechanism. 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 a plate stack, and drying and curing the plate stack to obtain a finished plate.

[0003] The existing stacking method to keep a single plate in a flat state is to use a conveyor belt to continuously output to the stacking mechanism, and the output method is mainly suction cup pick-up and inertial discharge self-stacking. The former method has low production efficiency, and the latter method has a faster discharge response speed. However, both of the above methods have the following problems: the grid is prone to slippage and displacement on the working surface of the conveyor belt, and the grid in a high-speed conveying state cannot adjust its bandwidth direction position in real time. During the inertial discharge process, the guide will shorten the stroke of the plate due to inertia, causing the grid to fall to a position close to the conveyor belt, affecting the normal stacking of the plate. Utility Model Content

[0004] The utility model aims to overcome the defects in the prior art and provide a continuous plate conveying and sorting mechanism, which uses the push-stopping member of the sorting assembly and the position change of the plate in the fan-shaped receiving space to correct the position of the plate.

[0005] In order to achieve the above technical effects, the technical solution of the utility model is: a plate continuous conveying and sorting mechanism, comprising:

[0006] The conveying roller comprises a rotatably arranged roller body, a plurality of supporting and limiting members alternately arranged on the circumference of the roller surface, and a fan-shaped receiving space for receiving at least one electrode plate;

[0011] A preferred technical solution is that the push member includes an extension portion located radially outside the annular arc portion, and the push surface includes an extended push area located on the extension portion;

[0012] The extension portion is located directly above the top end of the roller surface of the roller body, and the arc portion is extended on both sides of the extension portion.

[0013] A preferred technical solution is that the central angle corresponding to the extension portion is not less than the central angle corresponding to one of the fan-shaped receiving spaces.

[0014] A preferred technical solution is that the extension portion has a first end and a second end opposite to each other in the vertical direction, the first end is connected to the arc portion, and the push member is suspended above the roller body through the second end.

[0015] A preferred technical solution is that the finishing assembly further includes a reciprocating drive member, the reciprocating drive member has a driving end that reciprocates along the axial direction of the roller body, and the driving end is connected to the second end portion.

When the conveying roller rotates, the plate thickness side of the electrode plate close to the roller body abuts against the roller body, so that the positions of the electrode plates in the same or different fan-shaped receiving spaces along the radial direction of the roller body are consistent. The sorting mechanism pushes the electrode plates in the fan-shaped receiving spaces on the outer periphery of the conveying roller to align, so that the positions of the electrode plates in the same or different fan-shaped receiving spaces along the axial direction of the roller body are consistent.

DETAILED DESCRIPTION

[0030] 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.

[0031] 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.

[0032] 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. Example

[0033] like Figure 1-4As shown, the embodiment of the continuous conveying and sorting mechanism of the electrode plate includes a conveying roller 1 and a sorting assembly, the conveying roller 1 includes a rotatably arranged roller body 101, a plurality of supporting and limiting members 102 alternately arranged on the circumferential side of the roller surface, and a fan-shaped accommodating space for accommodating at least one electrode plate; the sorting assembly is arranged on at least one side of the roller body axial direction of the supporting and limiting member 102, and the sorting assembly 2 includes a pushing member 201; the pushing member 201 has a pushing surface for pushing the electrode plate.

[0034] The supporting limiter 102 and the fan-shaped receiving space are alternately arranged on the circumference of the roller surface. The supporting limiter 102 has the dual functions of supporting the pole plate and limiting the pole plate. The end of the supporting limiter 102 away from the roller body 101 is the free end, and the end of the supporting limiter 102 connected to the roller body 101 is the fixed end. When the supporting limiter 102 rotates to the side with the roller body 101, and the free end is flush with or higher than the fixed end, the supporting limiter 102 supports the pole plate; when the supporting limiter 102 rotates to the oblique upper side of the roller body 101, the plate thickness side of the pole plate abuts against the roller surface of the roller body 101, and the pole plate abuts against the side of the supporting limiter 102.

[0035] The cross section of the fan-shaped receiving space is fan-shaped, which is a through groove formed by adjacent supporting limit members 102 and the roller surface of the conveying roller 1. The slot of the through groove is away from the roller surface of the conveying roller 1, and the bottom of the slot is a partial roller surface of the conveying roller 1. The slot width gradually increases from the bottom of the slot to the slot, and a slot with a larger width is more conducive to the introduction of the electrode plate.

[0036] The roller surface of the conveying roller 1 is provided with a plurality of supporting and limiting members 102, and the central angle corresponding to the fan-shaped receiving space is preferably less than 45°, more preferably less than 30°, so that the plate can be turned over in the fan-shaped receiving space and does not leave the fan-shaped receiving space. If the central angle corresponding to the fan-shaped receiving space is too large, the force of turning the plate to abut against another supporting and limiting member 102 will be increased, and the probability of the lead paste coating being deformed by impact will be increased.

[0037] In this embodiment, 24 supporting and limiting members 102 are disposed on the roller surface of the conveying roller 1 .

[0038] The number of plates contained in the fan-shaped receiving space may be one, two, three or even more. Furthermore, the number of plates contained in a single fan-shaped receiving space is based on whether the plates can be turned over and moved in the fan-shaped receiving space. When the number of plates contained in the fan-shaped receiving space is more than two, the conveying rollers stack the plates in advance, and the plates in the same fan-shaped receiving space that rotate to the top of the conveying rollers are turned over in sequence or simultaneously.

[0039] Taking the clockwise rotation of the conveying roller 1 as an example, the first supporting and limiting member 102 is located on the clockwise side of the fan-shaped receiving space, and the second supporting and limiting member 102 is located on the counterclockwise side of the fan-shaped receiving space. In the process of the pole plate flipping with the conveying roller 1, the functions of the supporting and limiting members 102 on both sides of the fan-shaped receiving space change as follows: when the pole plate is located on the left side of the roller body 101 in the horizontal direction and the roller body 101 does not carry the pole plate, the second supporting and limiting member 102 carries the pole plate; when the pole plate is located on the left side of the roller body 101 in the horizontal direction and the roller body 101 carries the pole plate, the second supporting and limiting member 102 is located on the left side of the pole plate, and the pole plate abuts against the second supporting and limiting member 102; when the target fan-shaped receiving space is located directly above the roller body 101, the pole plate flips and the center of gravity shifts until the pole plate abuts against the second supporting and limiting member 102 on its right side, and the roller body 101 carries the pole plate; when the pole plate is located on the right side of the roller body 101 in the horizontal direction and the roller body 101 does not carry the pole plate, the first supporting and limiting member 102 carries the pole plate.

[0040] The sorting component 2 is arranged on the side of the plate transmission path of the conveying roller 1 to sort the plates in the fan-shaped receiving space, and the plates are always kept in the fan-shaped receiving space, which has high feasibility. In comparison, the front and back of the plates on the conveyor belt are arranged in sequence. When the sorting components 2 are arranged on both sides of the conveyor belt to adjust the position of the plates in the direction of the belt width, there are no blocking limiters on both sides of the conveying direction of the plates. Due to the pushing force, the plates are prone to relative displacement in the reverse conveying direction, which leads to the front plate overlapping with the rear plate or pushing the rear plate to displace, which is not conducive to the normal export of the plates from the conveyor belt, and has low feasibility.

[0041] Preferably, the finishing assembly 2 is arranged on both axial sides of the roller body supporting the limiting member 102 .

[0042] like Figure 1 As shown, in some preferred embodiments, the push member 201 includes an arc portion 2011 , and the push surface includes an arc push area located on the arc portion 2011 ; the arc portion 2011 is arranged above the roller body 101 .

[0043] The electrode plate has a first side surface and a second side surface that are opposite to each other along the axial direction of the roller body. The electrode plate flips with the conveying roller 1, and the path of the first side surface and the second side surface is an annular arc. One function of the annular arc portion 2011 is to block the outside of the first side surface and / or the second side surface to ensure that the electrode plate will not escape from the fan-shaped receiving space through the axial ends of the roller body of the fan-shaped receiving space; the second function of the annular arc portion 2011 is to push the first side surface and / or the second side surface of the electrode plate to achieve fine adjustment of the position of the electrode plate along the axial direction of the roller body.

[0044] When the electrode plate is a wet electrode plate, the area of ​​its first side and second side is much smaller than its plate surface. In addition, the wet electrode plate has a large weight. When the supporting limit member 102 is supported under the electrode plate, the paste has a slight deformation. The axial displacement of the roller body of the electrode plate not only overcomes the deformation of the wet electrode plate, but also needs to overcome the friction between the electrode plate and the supporting limit member 102. Therefore, the arc portion 2011 fine-tunes the axial position of the roller body of the electrode plate.

[0045] In some preferred embodiments, the push member 201 is an elastic sheet-shaped push member.

[0046] The dynamic friction between the push-stop 201 and the plate in the fan-shaped receiving space has a component in the thickness direction of the plate, which may cause the lead paste coating to separate from the grid body of the plate, or cause the adhesion between the grid body and the lead paste coating to decrease. Compared with the rigid push-stop 201, the elastic sheet-shaped push-stop has a larger deformation amplitude, which is conducive to reducing the pushing force between the push-stop 201 and the first side and / or the second side, and is conducive to reducing the deformation of the lead paste coating on the first side and / or the second side, avoiding defects such as separation of the edge of the lead paste coating from the grid body and reduced adhesion.

[0047] like Figure 1 As shown, in some preferred embodiments, the push member 201 includes an extension portion 2012 located radially outside the annular arc portion 2011, and the push surface includes an extended push area located at the extension portion 2012;

[0048] The extending portion 2012 is located directly above the top of the roller surface of the roller body 101 , and the arc portion 2011 is extended on both sides of the extending portion 2012 .

[0049] When the fan-shaped receiving space where the electrode plate is located rotates to the top of the roller body 101, the center of gravity of the electrode plate shifts and flips, and only the bottom surface of the electrode plate contacts the roller surface during the flipping process. The force required to drive the flipped electrode plate to move along the axial direction of the roller body is the first force, and the force required to drive the electrode plate supported by the supporting limiter 102 to move along the axial direction of the roller body is the second force. The deformation of the wet electrode plate and the friction between the supporting limiter 102 and the electrode plate surface make the first force much smaller than the second force. Therefore, compared with the annular arc portion 2011, the extension portion 2012 has the main function of correcting the position of the electrode plate.

[0050] Optionally, the push member 201 including the arc portion 2011 and the extension portion 2012 has a fixed position relative to the roller body 101 .

[0051] like Figure 2 As shown, in some preferred embodiments, the central angle α corresponding to the extension portion 2012 is not less than the central angle β corresponding to a sector-shaped receiving space.

[0052] When the fan-shaped receiving space rotates to the top of the roller body 101, the center of gravity of the pole plate shifts and flips, and the extension portion 2012 with the preferred central angle is completely blocked on the side of the fan-shaped receiving space, continuously pushing the pole plate during the flipping process, which is beneficial to further optimize the correction effect of the pole plate position.

[0053] Furthermore, the length of the radial extension portion 2012 along the roller body is greater than the length of the electrode plate, so that the extension portion 2012 pushes against the entire first side and / or second side of the electrode plate to disperse the abutting force and further reduce the deformation effect of the abutting force on the edge of the lead paste.

[0054] like Figure 1 As shown, in some preferred embodiments, the portion extending in the vertical direction 2012 has a first end a1 and a second end a2 relative to each other, the first end a1 is connected to the arc portion 2011 , and the push member 201 is suspended above the roller body 101 through the second end a2 .

[0055] Compared with the arc portion 2011, the extension portion 2012 is closer to the suspension connection. In addition to avoiding the rotation of the conveying roller 1, the gravity of the arc portion 2011 makes the extension portion 2012 smaller in the axial direction of the roller body, which is more conducive to correcting the center of gravity offset and flipping state of the pole plate; the arc portion 2011 has a larger deformation range.

[0056] like Figure 1 As shown, in some preferred embodiments, the finishing assembly 2 further includes a reciprocating driving member 202, and the reciprocating driving member 202 has a driving end that reciprocates along the axial direction of the roller body, and the driving end is connected to the second end a2.

[0057] Preferably, during the rotation of the conveying roller 1, the reciprocating driving member 202 drives the pushing member 201 to reciprocate along the axial direction of the roller body. As mentioned above, the arc portion 2011 has a larger deformation amplitude, and the deformation of the area of ​​the arc portion 2011 away from the extension portion 2012 is larger, and the axial pushing force of the roller body generated by the deformation is also larger; while the deformation amplitude of the extension portion 2012 is smaller, and the axial pushing force of the roller body generated by the deformation is also smaller. The changes in the pushing force and the pushing amplitude caused by the reciprocating driving member 202 are consistent with the pushing force and displacement changes required for the electrode plate to be in different positions, which is beneficial to further optimize the position correction effect of the electrode plate, reduce the deformation of the lead paste coating, and reduce the defective rate and loss of the continuous conveying of the electrode plate.

[0058] like Figure 1As shown, in some preferred embodiments, the arc portion 2011 is concentric with the roller body 101 and is spaced apart from each other. The arc portion 2011 abuts against the push area of ​​the first side surface and / or the second side surface, and the push area is spaced apart from the roller surface of the conveying roller 1. The arc portion 2011 is spaced apart from the roller body 101, and when the reciprocating driving member 202 drives the push member 201, the arc portion 2011 is ensured to have a predetermined deformation amplitude, so as to avoid direct contact between the deformed arc portion 2011 and the roller surface.

[0059] like Figure 4 As shown, in some preferred embodiments, the outer diameter of the arc portion 2011 is L1, the supporting limit member 102 has a first area for supporting the electrode plate, the length of the first area along the radial direction of the roller body is L2, and L1 is not less than half of L2, so that the outer edge of the arc portion 2011 is blocked in the radial middle area of ​​the roller body on the first side and / or the second side and the outside of the middle area, further optimizing the pushing and fine-tuning effect of the arc portion 2011 on the electrode plate.

[0060] like Figure 3 , 5 As shown, in some preferred embodiments, the electrode plate continuous conveying and sorting mechanism also includes a continuous feeding mechanism and a continuous discharging mechanism; the continuous feeding mechanism is configured to feed the electrode plates into the fan-shaped receiving space in sequence along the circumference of the conveying roller 1; the continuous discharging mechanism is configured to guide the electrode plates in the fan-shaped receiving space in sequence along the circumference of the conveying roller 1.

[0061] The continuous feeding mechanism is a plate-by-plate feeding mechanism, including but not limited to the combination of the feeding conveyor belt 3 and the accelerating roller 4 of the present embodiment; similarly, the function of the continuous discharging mechanism is to guide out the plate supporting the limiter 102, including but not limited to the discharging conveyor belt 5 of the present embodiment, and can also be a known device such as a manipulator. It can be understood that in order to increase the inertial force of the feeding plate, the feeding conveyor belt 3 can optionally include at least two unit conveyor belts with successively increasing conveying speeds. The feeding conveyor belt 3 and the discharging conveyor belt 5 can be selected as conveyor chains.

[0062] The structure of the support and limit member 102 is determined according to the selection of the continuous feeding mechanism and the continuous discharging mechanism, including but not limited to the comb shape in this embodiment. The optional feeding direction of the continuous feeding mechanism and the optional discharging direction of the continuous discharging mechanism are as follows: Figure 3 Indicated by the arrow.

[0063] Taking the push-stop members 201 disposed on both sides of the roller body supporting the limit member 102 as an example, the working process of the electrode plate continuous conveying and sorting mechanism includes the following steps:

[0064] S1: The electrode plate is located in a fan-shaped receiving space on the side of the central axis of the conveying roller 1 and is supported by the supporting and limiting member 102 below it;

[0065] S2: As the conveying roller 1 continues to rotate, the electrode plate gradually moves to the upper side of the central axis of the conveying roller 1. Except for the supporting limiter 102 supported below, the thick bottom surface of the electrode plate abuts against the roller surface of the conveying roller 1.

[0066] In this process, the arc portion 2011 of the push member 201 is disposed on both sides of the roller body in the fan-shaped receiving space, and the reciprocating driving member 202 drives the push member 201 to reciprocate along the axial direction of the roller body, and the arc portion 2011 slaps the first side surface and the second side surface of the electrode plate to fine-tune the axial position of the roller body of the electrode plate;

[0067] S3: As the conveying roller 1 continues to rotate, the electrode plate gradually moves to the top of the conveying roller 1, and the center of gravity of the electrode plate shifts and turns to abut against another supporting stopper 102 on the side of the conveying roller 1 in the rotation direction, and at the same time, the thick bottom surface of the electrode plate abuts against the roller surface of the conveying roller 1;

[0068] During the flipping process, the extension part 2012 of the push member 201 pushes the electrode plate to further correct and adjust the axial position of the roller body of the electrode plate;

[0069] S4: As the conveying roller 1 continues to rotate, the electrode plate gradually moves to the other side of the central axis of the conveying roller 1 and is carried by another supporting and limiting member 102 in S3;

[0070] During this process, due to the push of the annular arc portion 2011, the electrode plate maintains the corrected axial position of the roller body, or the axial position of the roller body of the electrode plate is further fine-tuned.

[0071] 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.
