Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery plate production equipment, in particular to a high-speed plate stacking mechanism and a plate collecting device. 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 introducing the plate stack into a heating device for curing and drying.

[0003] The stacking mechanism of the plate usually includes a first conveyor belt and a stacking platform located at the discharge side of the first conveyor belt. The first conveyor belt outputs the plates in sequence, and the stacking platform gradually decreases in height to ensure that its top has a fixed height difference with the discharge end of the first conveyor belt. The plates have similar masses, so the displacement caused by their inertia is also similar. The fixed height difference allows the plates to be separated from the first conveyor and transported to a predetermined position, ensuring that the plates are neatly stacked.

[0004] The defect of the above stacking operation is that when the stacking platform descends to the lowest position, that is, when a predetermined number of plates are stacked on the stacking platform, the plate stack of the stacking platform is unloaded, and then the stacking platform must rise from its lowest position to the highest position to start stacking the subsequent continuously output plates. The plates obtained by the continuous slitting mechanism are distributed in sequence and unloaded by the first conveyor belt. The slitting mechanism and the first conveyor belt must be suspended during the rising period of the stacking platform, which is not conducive to improving the production efficiency of the slitting mechanism and the stacking mechanism, and is not conducive to achieving high-speed production of lead-acid battery plates. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects in the prior art and provide a high-speed plate stacking mechanism to ensure continuous production of the slitting mechanism and the first conveyor belt, thereby improving the production efficiency of the slitting mechanism and the stacking mechanism.

[0006] In order to achieve the above technical effects, the technical solution of the utility model is: a high-speed plate stacking mechanism, comprising:

[0007] The first conveyor belt;

[0008] A lifting and stacking platform is fixedly arranged on the discharge side of the first conveyor belt, and includes a first supporting surface for carrying the electrode plate;

[0009] A discharging mechanism configured to discharge the plate stack; and further comprising:

[0010] The stacking transfer mechanism has a second supporting surface for carrying the electrode plate and is removable and liftable and arranged directly above the first supporting surface, and is configured to drive the electrode plate or the electrode plate stack on the second supporting surface to be transferred to the first supporting surface along the plumb direction.

[0011] A preferred technical solution is that the width direction of the first conveyor belt is the first direction;

[0012] The lifting and stacking platform comprises a first supporting member having a first supporting surface;

[0013] The stacking transfer mechanism comprises a second supporting member having a second supporting surface, wherein the second supporting member is removable and is arranged opposite to both sides of the first supporting member in the first direction along the plumb direction and / or spaced apart from the first supporting member in the first direction.

[0014] A preferred technical solution is that the conveying direction of the first conveyor belt is the second direction; the second supporting member is removably arranged on the side of the lifting and stacking platform away from the first conveyor belt;

[0015] The palletizing transfer mechanism includes a transverse movement mechanism, and the transverse movement mechanism is configured to drive the second supporting member to move back and forth along the second direction.

[0016] A preferred technical solution is that the stacking transfer mechanism includes a lifting mechanism, and the lifting mechanism is configured to drive the second supporting member to move along the plumb direction.

[0017] A preferred technical solution is that the second supporting member has a free end close to the lifting and stacking platform, the plumb bob thickness of the free end gradually increases along the second direction, and an acute angle is formed between the bottom surface of the free end and the second supporting surface.

[0018] A preferred technical solution is that the discharging mechanism is a second conveyor belt.

[0019] A preferred technical solution is that the stacking transfer mechanism further includes a baffle, which is fixedly disposed on the side of the lifting stacking platform away from the first conveyor belt, and the baffle is provided with a through hole or a notch for accommodating the passage of the second supporting member.

[0020] The preferred technical solution is that the opening of the notch is arranged plumb downward.

[0021] The preferred technical solution is that it also includes a stacking and sorting mechanism arranged on the feed side and / or discharge side of the lifting stacking platform, and the stacking and sorting mechanism has a pushing surface that pushes against the thickness side of the electrode plate, and a pushing mechanism that drives the pushing surface to move toward or away from the lifting stacking platform.

[0022] The second object of the utility model is to provide a sheet collecting device, including the above-mentioned high-speed plate stacking mechanism.

[0023] The advantages and beneficial effects of the utility model are:

[0024] The plate high-speed stacking mechanism has a reasonable structure. During a relatively long period of time when the lifting stacking platform rises from its lowest position to a predetermined top surface height, the plates continuously guided out by the first conveyor belt are discharged to the second supporting surface of the stacking transfer mechanism and stacked. During the rising process of the lifting stacking platform, the plates or plate stacks on the second supporting surface and the first supporting surface are transferred and handed over.

[0025] By adding a stacking transfer mechanism, the slitting mechanism and the first conveyor belt do not need to be paused to adapt to the lifting stacking platform, which is beneficial to improving the production efficiency of the slitting mechanism and the stacking mechanism to achieve high-speed production of lead-acid battery plates.

[0039] 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.

[0040] 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.

[0041] 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

[0042] like Figure 1-5 As shown, the embodiment of the high-speed stacking mechanism of the plate comprises a first conveyor belt 1, a lifting stacking platform 2, a discharging mechanism 3 and a stacking transfer mechanism 4; the lifting stacking platform 2 is fixedly arranged on the discharging side of the first conveyor belt 1, and the lifting stacking platform 2 comprises a first supporting surface 2a for carrying the plate; the discharging mechanism 3 is configured to export the plate stack; the stacking transfer mechanism 4 has a second supporting surface 4a for carrying the plate, which is removable and liftable and arranged directly above the first supporting surface 2a, and the stacking transfer mechanism 4 is configured to drive the plate or the plate stack on the second supporting surface 4a to transfer to the first supporting surface 2a along the plumb direction.

[0043] The function of the first conveyor belt 1 is to continuously output the cut single-piece plates. It has a working surface for carrying the plates and enables the single-piece plates to have a predetermined conveying direction speed so that the plates separated from the first conveyor belt 1 maintain their linear motion state and fall to the lifting and stacking platform 2.

[0044] The function of the lifting and stacking platform 2 is to carry the stacked plates. The more the number of stacked plates, the higher the plate stack. In order to ensure that the assembly of the lifting and stacking platform 2 and the plates on it has a top surface of a predetermined height, the first supporting member with the first supporting surface 2a must be lifted and set with the corresponding frame. It can be understood that the lifting and lowering of the first supporting member is in the plumb bob direction.

[0045] The function of the discharging mechanism 3 is to discharge the electrode plate stack, including but not limited to a conveyor belt, a robot and other mechanisms that cooperate with the movement of the lifting and stacking platform 2.

[0046] The function of the stacking transfer mechanism 4 is to provide a second supporting surface 4a as a base surface for stacking the plates, and to realize the transfer and handover of the plates or plate stacks between the second supporting surface 4a and the first supporting surface 2a. The number of plates transferred from the second supporting surface 4a to the first supporting surface 2a depends on the rising time of the lifting stacking platform 2, and the factors affecting the rising time of the lifting stacking platform 2 include the number of plate stacks that meet the export requirements, the thickness of the plates, the rising speed of the lifting stacking platform 2, and the plate discharge frequency of the first conveyor belt 1. When the rising time period of the lifting stacking platform 2 is short enough, the second supporting surface 4a can be used to carry only a single plate and transfer it to the first supporting surface 2a; when the rising time period of the lifting stacking platform 2 is long, the second supporting surface 4a carries more than two plates and transfers them to the first supporting surface 2a.

[0047] The first supporting surface 2a and the second supporting surface 4a are both used to support the electrode plates or electrode plate stacks. The top surfaces of the electrode plates or electrode plate stacks on the first supporting surface 2a and the second supporting surface 4a are not blocked, so that the top surfaces of the electrode plates or electrode plate stacks can still be used to receive the discharged electrode plates during the transfer and handover process, thereby meeting the high frequency of the first conveyor belt 1 to export the electrode plates.

[0048] The electrode plate or electrode plate stack is transferred to the first supporting surface 2a along the plumb direction. During the handover process, the electrode plate or electrode plate stack is located directly above the first supporting surface 2a to prevent the electrode plate or electrode plate stack from exerting a horizontal force on the discharged electrode plate. If the electrode plate or electrode plate stack is translated laterally in the width direction of the conveyor belt to the handover position, the movement direction of the electrode plate or electrode plate stack on the second supporting surface 4a is not the same as or opposite to the movement direction of the discharged electrode plate of the first conveyor belt 1, but is sandwiched at a right angle, an acute angle or an obtuse angle. The angle of the movement direction will cause the electrode plate stack to be less neat, especially the upper electrode plate.

[0049] In this embodiment, the first conveyor belt 1 is a conveyor chain.

[0050] like Figure 1-4 As shown, in some preferred embodiments, the width direction of the first conveyor belt 1 is the first direction ( Figure 1 , 2X direction); the lifting and stacking platform 2 includes a first supporting member 201 with a first supporting surface 2a; the stacking transfer mechanism 4 includes a second supporting member 401 with a second supporting surface 4a, and the second supporting member 401 is removable and arranged along the plumb direction on both sides of the first direction of the first supporting member 201 and / or the first direction of the first supporting member 201.

[0051] The lifting and stacking platform 2 further includes a lifting mechanism 202 for driving the first supporting member 201 to rise and fall.

[0052] The second supporting member 401 has an avoidance station and a stacking station. The second supporting surface 4a of the avoidance station is located above the side of the first supporting surface 2a, including but not limited to the side above the length direction or width direction of the first conveyor belt 1, and any position around the first supporting surface 2a can be selected. The second supporting surface 4a of the stacking station is located directly above the first supporting surface 2a, which does not mean that the second supporting member 401 is located directly above the first supporting member 201. When the first supporting surface 2a and the second supporting surface 4a are both composed of two or more corresponding supporting member top surfaces, the combination center of the second supporting surface 4a is located directly above the combination center of the first supporting surface 2a.

[0053] The relative positions of the first supporting member 201 and the second supporting member 401 of the palletizing station include but are not limited to: two second supporting members 401 are respectively arranged above the first direction side of a first supporting member 201; one second supporting member 401 is located above the interval area between the two first supporting members 201; as shown in the figure, two or more second supporting members 401 along the first direction are arranged in the interval between two or more first supporting members 201 in the vertical direction.

[0054] like Figure 1-4 As shown, in some preferred embodiments, the conveying direction of the first conveyor belt 1 is the second direction ( Figure 1 , 2 Y direction); the second supporting member 401 is removably arranged on the side of the lifting and stacking platform 2 away from the first conveyor belt 1; the stacking transfer mechanism 4 includes a transverse movement mechanism 402, which is configured to drive the second supporting member 401 to move back and forth along the second direction.

[0055] The second supporting member 401 of the avoidance station is located on the side of the lifting and stacking platform 2 away from the first conveyor belt 1. When the second supporting member 401 is switched from the avoidance station to the stacking station, it is displaced in the opposite direction of the second direction. Compared with the displacement of the second supporting member 401 in any direction having a component in the first direction, the movement of the second supporting member 401 can avoid the stacking deviation of its upper plate in the first direction.

[0056] like Figure 2 , 3As shown, in some preferred embodiments, the palletizing transfer mechanism 4 includes a lifting mechanism 403, and the lifting mechanism 403 is configured to drive the second supporting member 401 to move along the plumb direction.

[0057] In this embodiment, the lifting mechanism 403 is connected to the second supporting member 401 through the transverse movement mechanism 402. The lifting mechanism 403 includes but is not limited to a cylinder, a hydraulic cylinder and an electric cylinder.

[0058] like Figure 4 As shown, in some preferred embodiments, the second supporting member 401 has a free end 4011 close to the lifting and stacking platform 2, the plumb thickness of the free end 4011 gradually increases along the second direction, and the bottom surface of the free end 4011 is provided with an acute angle with the second supporting surface 4a.

[0059] When the lifting and stacking platform 2 is at the lowest position, the top surface of the assembly of the lifting and stacking platform 2 and the plate stack is at a predetermined stacking height, the second supporting member 401 is switched from the avoidance position to the stacking position, the height of the second supporting member 401 is also at the predetermined stacking height, and the lifting and stacking platform 2 further descends to avoid the lateral movement of the second supporting member 401.

[0060] During the lateral movement, there is no electrode plate on the second supporting member 401, and the lateral movement stroke of the second supporting member 401 is much larger than the descending stroke of the lifting and stacking platform 2. Therefore, the descending speed of the lifting and stacking platform 2 is much smaller than the lateral movement speed of the second supporting member 401 without electrode plates. The preferred structure of the free end 4011 is beneficial for the second supporting member 401 to avoid the descending electrode plate stack; it prevents the free end 4011 of the second supporting member 401 from impacting the top electrode plate of the lifting and stacking platform 2 during the lateral movement, thereby affecting the neatness of stacking.

[0061] It can be understood that in order to ensure the supporting stability of the electrode plate stacking structure, the first supporting surface 2a and the second supporting surface 4a are horizontal surfaces.

[0062] like Figure 3 As shown, in some preferred embodiments, the discharging mechanism 3 is a second conveyor belt. In this embodiment, the second conveyor belt is a conveyor chain.

[0063] Compared with the grabbing mechanism, the second conveyor belt is carried under the pole plate stack, which meets the continuous output production requirements of the pole plate stack and has a fast response speed.

[0064] In this embodiment, there are two second conveyor belts and they are arranged in the interval of the first supporting member 201. The second conveyor belt maintains the conveying speed. When the first supporting surface 2a drops below the working surface of the second conveyor belt, the pole plate stack is transferred to the working surface of the second conveyor belt and is guided out along the conveying direction; when the pole plate stack is moved to the upper side of the first supporting surface 2a, the first supporting member 201 moves upward and resets.

[0065] like Figure 3 , 4 As shown, in some preferred embodiments, the stacking transfer mechanism 4 also includes a baffle 404, which is fixedly arranged on the side of the lifting stacking platform 2 away from the first conveyor belt 1, and the baffle 404 is provided with a through hole or a notch 405 for accommodating the passage of the second supporting member 401.

[0066] The baffle 404 is used to limit the displacement of the inertial plates discharged from the first conveyor belt 1 along the second direction, block the plates and guide them to fall into place, and improve the neatness of the stacking of the plates; usually, the lifting and driving mechanism accuracy of the second supporting member 401 is less than the lifting and driving mechanism accuracy of the second supporting member 401. When the time for the first supporting member 201 to rise from the lowest position to the transfer position is too long, the second supporting member 401 needs to carry more plates, and the baffle 404 is conducive to improving the stability of the plate stack on the second supporting member 401.

[0067] like Figure 4 As shown, in some preferred embodiments, the opening of the notch 405 is arranged to be plumb downward.

[0068] The vertical height of the through hole is related to the time it takes for the first supporting member 201 to rise from the lowest position to the intermediate transfer position. When the time it takes for the first supporting member 201 to rise from the lowest position to the intermediate transfer position is longer, compared with the through hole, the downward opening of the notch 405 makes the number of plates carried by the second supporting member 401 limited only by the lifting stroke of the second supporting member 401, which is helpful for dealing with the sudden problems of the first supporting member 201 failure and the upward time process.

[0069] like Figure 3 As shown, in some preferred embodiments, the high-speed plate stacking mechanism also includes a stacking and sorting mechanism 5 arranged on the feed side and / or the discharge side of the lifting stacking platform 2, and the stacking and sorting mechanism 5 has a pushing surface 5a that pushes against the thickness side of the plate, and a pushing mechanism 501 that drives the pushing surface 5a to move toward or away from the lifting stacking platform 2.

[0070] The stacking and sorting mechanism 5 acts to push the side of the plate thickness in the second direction or the opposite direction of the second direction, thereby increasing the stacking positive degree of the side opposite to the second direction of the plate. Furthermore, the stacking and sorting mechanism 5 is arranged based on the baffle 404. The plate discharged from the first conveyor belt 1 collides with the baffle 404, rebounds to varying degrees or falls along the baffle 404, and the side of the rebounded plate protrudes from the side of the plate below it, and the push surface 5a pushes the protruding plate to be flush with the side of the other plate.

[0071] Optionally, the number of plate discharges corresponds one-to-one to the number of reciprocating movements of the push surface 5a, or the number of plate discharges is an integer multiple greater than 1 of the number of reciprocating movements of the push surface 5a.

[0072] The sheet collecting device of the embodiment includes the above-mentioned electrode plate high-speed stacking mechanism. The stacking and sorting mechanism 5 is arranged on two opposite sides of the lifting stacking platform 2 in the second direction.

[0073] The working process of the plate high-speed stacking mechanism is:

[0074] S1, the first conveyor belt 1 discharges the plate to the first supporting surface 2a of the lifting stacking platform 2, and the lifting stacking platform 2 gradually decreases in height, such as Figure 5 As shown;

[0075] S2. When the plates on the lifting and stacking platform 2 reach a predetermined number, the lifting and stacking platform 2 descends and transfers the plate stack to the discharging mechanism 3. The discharging mechanism 3 discharges the plate stack, and the lifting and stacking platform 2 moves upward and resets. At the same time, the transverse movement mechanism 402 drives the second supporting member 401 to extend in the opposite direction of the second direction until the second supporting surface 4a is located directly above the first supporting surface 2a. The first conveyor belt 1 discharges the plate to the second supporting surface 4a, and the lifting mechanism 403 drives the second supporting member 401 to descend in height successively. Figure 6 As shown;

[0076] S3, the lifting mechanism 403 drives the second supporting member 401 downward, and the lifting mechanism 202 drives the first supporting member 201 upward. When the first supporting surface 2a is higher than the second supporting surface 4a, the plate stack is transferred to the first supporting surface 2a. Figure 7 As shown;

[0077] S4, the lateral movement mechanism 402 drives the second supporting member 401 to reset along the second direction. Figure 8 As shown, the lifting mechanism 403 then drives the second supporting member 401 upward to Figure 5 Position shown.

[0078] 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.
