Description

Technical Field

[0001] This application relates to the field of intelligent equipment technology for lead-acid batteries, and in particular to a small-to-medium density positive and negative electrode plate collecting machine. Background Technology

[0002] The small- and medium-density positive and negative electrode plates output from the surface-drying kiln still contain moisture and heat. If two electrode plates overlap completely or partially, the moisture on their surfaces will cause them to stick together. Currently, the plate-collecting equipment for small- and medium-density electrode plates uses vacuum adsorption to transfer the plates to the collection line. However, the vacuum breaking process of the vacuum conveyor is affected by factors such as air volume, the current adsorption force of the perforated belt, and time accumulation. Actual errors in vacuum breaking can lead to some electrode plates overlapping and sticking together after falling, resulting in uneven edges on the electrode plate assembly and making subsequent finishing difficult. Furthermore, the electrode plates are 2-3mm thick; if the adhesion is severe, it can damage the plates during finishing, requiring frequent shutdowns for vacuum line alignment. This prevents the collection equipment from operating continuously for the entire shift, impacting production speed. Summary of the Invention

[0003] In view of this, the present invention provides a small-to-medium density positive and negative electrode plate collecting machine, which can realize the collecting, stacking and sorting of small-to-medium density plates, and is set to operate continuously with high production efficiency.

[0004] An embodiment of the present invention provides a small-to-medium density positive and negative electrode plate collecting machine, comprising: A frame; a first conveyor unit is disposed within the frame; a vacuum conveyor belt is disposed above the first conveyor unit; one end of the vacuum conveyor belt extends forward past the starting end of the first conveyor unit; a transfer line is disposed between the first conveyor unit and the vacuum conveyor belt; the transfer line includes a first conveyor line and a second conveyor line arranged in a front-to-back configuration; the main chamber of the vacuum conveyor belt contains an independent first chamber and a second chamber that are not connected to the main chamber, the first chamber being located above the first conveyor line and the second chamber being located above the second conveyor line; a first shuttle valve assembly connected to the first chamber is disposed on the vacuum conveyor belt, the first shuttle valve assembly being configured to create a vacuum negative pressure and break the vacuum within the first chamber; air blowing assemblies are disposed in the first chamber and the second chamber; a plate-collecting device is configured to stack several electrode plates into an electrode plate assembly, disposed within the first conveyor unit; the plate-collecting assembly is disposed at the end of both the first and second conveyor lines; a sorting device is disposed at the end of the first conveyor unit and is configured to sort and flatten the electrode plate assembly; a second conveyor unit is configured to convey the electrode plate assembly within the sorting device to the rear end.

[0005] In a preferred embodiment, the vacuum conveyor belt includes a base and a perforated belt covering the base. The base contains a main chamber, and a main pipe connected to a negative pressure fan is located above the base. Several branch pipes connecting the main chamber and the main pipe are located on the top of the base. A perforated plate is located at the bottom of the base. When the perforated belt is running, it adheres to the lower surface of the perforated plate. After the negative pressure fan is started, the perforated belt forms an adsorption force.

[0006] The front end of the vacuum belt conveyor extends above the surface drying kiln conveyor line. The electrode plates conveyed below the vacuum belt conveyor are attracted by its lower surface. The perforated belt drive within the vacuum belt conveyor transports the electrode plates above the first conveyor line. The first shuttle valve assembly in the first chamber breaks the vacuum, allowing the electrode plates to automatically fall onto the first conveyor line. The first conveyor line transports the electrode plates one by one to the plate-collecting device. After the current plate-collecting device completes the stacking and collecting of one electrode plate assembly, the material support assembly descends below the first conveyor unit, and the electrode plate assembly automatically transfers to the first conveyor unit. The moment the plate-collecting device completes collecting, the first conveyor line stops operating. The first shuttle valve assembly in the first chamber creates a negative pressure in the chamber, allowing the electrode plates attracted below the vacuum belt conveyor to be transported backward through the first chamber to the top of the second conveyor line. Since no negative pressure is created in the second chamber, the electrode plates automatically fall onto the second conveyor line after reaching the bottom of the second chamber. The first and second conveyor lines serve as intermediate links between the vacuum belt conveyor and the plate take-up device. The speed of the plates after transmission is adjusted by the conveyor lines, eliminating the occurrence of adhesion.

[0007] Furthermore, guide components are provided at both ends of the base; the guide components include two guide wheels located on both sides of the pulley, and the side of the perforated belt contacts the outer circular surface of the guide wheel.

[0008] Furthermore, both the first and second conveyor lines include two opposing support plates, which are connected to a bracket; a conveyor assembly including several circulating conveyor chains is provided between the support plates; a tray is provided between the support plates, passing through the annular space formed by the circulating conveyor chains, and a guide block is provided on the top of the tray that contacts the lower surface of the upper chain.

[0009] Furthermore, guide components are provided at the ends of both the first and second conveyor lines. Each guide component includes a pressure roller and several smooth wheels. The smooth wheels are mounted on the sprockets of the conveyor components, and the smooth wheels and sprockets are fixedly connected by welding. The pressure roller is located above the smooth wheels. Connecting plates at both ends of the pressure roller are connected to the support plate via rotating shafts. A first pin is provided on the connecting plate, and a second pin is provided on the support plate; the first pin and the second pin are connected by a tension spring.

[0010] In a preferred embodiment, the receiving device includes a baffle assembly, a material support assembly, and a drive assembly. The material support assembly includes a horizontally placed base plate and several support plates fixed to the top of the base plate. The top of the support plates forms a platform for receiving the electrode plates. The baffle assembly is an integral stamped sheet metal sheet, including a fixing part fixedly connected to a support plate. Several L-shaped baffles are provided on one side of the fixing part corresponding to the support plate. An interval area is formed between adjacent L-shaped baffles, and one end of the support plate corresponding to the L-shaped baffle is located in the interval area.

[0011] In a preferred embodiment, the sorting unit is disposed between the first conveying unit and the second conveying unit. The sorting device includes a bracket, a rotating shaft, a square rotating part, and a motor. The rotating shaft is horizontally disposed in the bracket and is fixedly connected to the rotating part. The motor drives the rotating shaft to rotate. The rotating part includes a first side plate, a second side plate, a third side plate, and a fourth side plate connected end to end. Mounting seats are provided on the first side plate and the third side plate. A receiving device including a carrier plate and a vibrator is installed on the rotating part. The carrier plate and the mounting seat are connected by a rubber pad. The vibrator is installed between the carrier plate and the mounting seat, and the output shaft of the vibrator is connected to the carrier plate. Limiting plates extending to both sides of the mounting seat are provided on the second side plate and the fourth side plate. A receiving space for the electrode assembly is formed between the limiting plates and the carrier plate.

[0012] Furthermore, the sorting device also includes a patting mechanism located above the rotating part. The patting mechanism includes a guide rod whose end is connected to the bracket, and two patting plates sleeved on the guide rod. A third cylinder mounted on the bracket drives the two patting plates to move towards each other or away from each other.

[0013] In a preferred embodiment, a proximity switch or photoelectric sensor is provided on the side of the vacuum conveyor belt; a third chamber, independent and not connected to the main chamber of the vacuum conveyor belt, is located on the side of the first chamber relative to the second chamber; a second shuttle valve assembly connected to the third chamber is provided on the vacuum conveyor belt, and the second shuttle valve assembly is configured to create a vacuum negative pressure and break the vacuum in the third chamber. In another preferred embodiment, a cylinder is provided above the end of the vacuum conveyor belt, and the extension rod of the cylinder is hinged to the end of the vacuum conveyor belt.

[0014] In summary, the first and second conveyor lines serve as intermediate transfer lines between the vacuum belt conveyor and the plate-receiving device. The speed at which the plates are transferred backward is adjusted by the conveyor lines, eliminating adhesion and ensuring normal operation of the equipment. Furthermore, the two conveyor lines, matched with the vacuum belt conveyor for plate receiving, enable non-stop plate receiving, thereby improving the production efficiency of the plate-receiving machine.

Detailed Implementation

[0016] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] Figure 1 The image shown is electrode assembly A, formed by stacking several electrode plates. The function of this equipment is to collect, stack, and arrange the electrode plates output from the surface drying kiln. Figure 1 The shape shown.

[0018] Figure 2 and Figure 3 The small-to-medium density positive and negative electrode plate collecting machine shown includes a frame 100. Two opposing front upright plates 101 are positioned above the frame, and a first conveying unit 200 is located between the two front upright plates. A vacuum conveyor belt 300 is positioned above the first conveying unit, with the side of the vacuum conveyor belt corresponding to the first conveying unit serving as an adsorption surface. (See also...) Figure 3A first conveyor line 400 and a second conveyor line 500 are arranged in a front-to-back manner between the vacuum belt conveyor and the first conveying unit. A plate collection device 600 is provided at the end of both the first and second conveyor lines. The electrode plates adsorbed below the vacuum belt conveyor fall downward into the first or second conveyor line, and the plate collection device stacks several electrode plates into an electrode plate assembly.

[0019] like Figure 4 As shown, the vacuum belt conveyor 300 includes a base 310 and a perforated belt 311 covering the base. Guide components are provided at both ends of the base 310, including two guide wheels 313 located on either side of the pulleys 312. The side of the perforated belt contacts the outer surface of the guide wheels. A main chamber is provided inside the base of the vacuum belt conveyor. A main pipe 314 connected to a negative pressure fan is provided above the base. Several branch pipes 315 connecting the main chamber and the main pipe are provided at the top of the base. A perforated plate is provided at the bottom of the base 310. During operation, the perforated belt adheres to the lower surface of the perforated plate 316. After the negative pressure fan starts, the perforated belt generates an adsorption force, firmly adsorbing the electrode plates onto the lower surface.

[0020] The main chamber of the vacuum conveyor belt is equipped with an independent first chamber and a second chamber that are not connected to the main chamber. The first chamber is located above the first conveyor line, and the second chamber is located above the second conveyor line. Since the first chamber is not connected to the main chamber, the perforated belt running below the first chamber has no suction force. After the electrode plate reaches the bottom of the first chamber, it will automatically fall onto the first conveyor line 400, which then transports the electrode plate to the receiving device 600.

[0021] After collecting one electrode assembly, the collecting device 600 needs to transfer the assembly to the first conveying unit 200. During this transfer, the collecting device 600 cannot receive any more electrodes from the vacuum conveyor belt. Therefore, this embodiment includes a second conveyor line 500. Since the first chamber is not connected to the main chamber, the perforated belt running below the second chamber has no suction force. After reaching the bottom of the second chamber, the electrodes automatically fall onto the second conveyor line 500, which then transports them to the corresponding collecting device.

[0022] A first shuttle valve assembly 320 connected to the first chamber is provided on the vacuum belt. The first shuttle valve assembly is configured to create a vacuum negative pressure and break the vacuum in the first chamber. When the first conveyor line starts to receive the electrode plate, the first shuttle valve assembly breaks the vacuum in the first chamber. When the second conveyor line starts to receive the electrode plate, the first shuttle valve assembly creates a vacuum negative pressure in the first chamber, and the electrode plate is smoothly conveyed to the bottom of the second chamber.

[0023] In this embodiment, both the first and second chambers are equipped with downward blowing assemblies 330 to assist the electrode plate in disengaging downwards from the vacuum conveyor belt, preventing the electrode plate from being transported to the rear by the vacuum conveyor belt and ensuring the smooth operation of the entire device. Preferably, the blowing assembly uses a stainless steel flat nozzle.

[0024] The base has two first partitions 340 extending towards the perforated plate, forming a first chamber inside the base; the base also has two second partitions extending towards the perforated plate, forming a second chamber inside the base. Supports 350 are provided on the inner sides of the first and second partitions, and the air-blowing assembly is mounted on the supports.

[0025] In actual operation, the front end of the vacuum belt conveyor extends above the surface drying kiln conveyor line, with the lower adsorption surface of the perforated belt approximately 10mm-15mm away from the kiln conveyor line. The perforated belt is a wear part and requires regular replacement and maintenance. In this embodiment, a first cylinder 360 is installed above the end of the vacuum belt conveyor. The telescopic rod of the first cylinder is hinged to the end of the vacuum belt conveyor. When the telescopic rod retracts, the end of the vacuum belt conveyor 300 is raised, increasing the distance between the front end of the vacuum belt conveyor and the surface drying kiln conveyor line, facilitating operator control.

[0026] In some embodiments, if the plate-collecting speed of the first and second conveyor lines is lower than the speed of the surface drying kiln conveyor line, one or more conveyor lines can be added between the first and second conveyor lines, and an independent chamber can be added in the main chamber corresponding to the conveyor line, and an independent shuttle valve assembly can be provided for the chamber.

[0027] The main structures of the first and second conveyor lines are the same, as described below. Figure 7 The main structures of both are described below. The first conveyor line 400 includes two opposing support plates 410, which are fixedly connected to the front upright plate 101. A conveyor assembly 420, comprising several circulating conveyor chains, is disposed between the two support plates. A support plate 430, passing through an annular space formed by the circulating conveyor chains, is disposed between the two support plates. A guide block 440, contacting the lower surface of the upper chain, is located on the top of the support plate. The guide block lifts the circulating conveyor chains upward, keeping the conveying surface of the first conveyor line horizontal. A second cylinder 450, connected to the conveyor assembly, is mounted on the support plate. When maintenance is required for both the first and second conveyor lines, the second cylinder 450 lifts the conveyor assembly upward.

[0028] See Figure 9The plate collecting device 600 includes a baffle assembly 610, a material support assembly 620, and a drive assembly 630. The baffle assembly blocks the electrode plates, causing them to fall downwards onto the material support assembly. The drive assembly drives the material support assembly to descend in stages, achieving multi-stage plate collecting. The material support assembly 610 includes a horizontally placed base plate 611 and several support plates 612 fixed to the top of the base plate. The top of the support plates forms a platform for receiving the electrode plates. The electrode plates enter the collecting device one by one for stacking. The drive assembly drives the material release assembly to descend in stages, keeping the receiving surface at a set height. The drive assembly 630 includes a base 631, a ball screw 632, and a servo motor 633. The base plate 611 is fixed to the top of the base. One end of the base is connected to the bushing of the ball screw, and the other end extends to the bottom of the base plate and is fixed thereto. The servo motor drives the screw in the ball screw to rotate through a pulley assembly 634, thereby driving the support plates to rise and fall. The baffle assembly includes a fixing part 611 fixedly connected to the support plate. Several L-shaped baffles 612 are provided on one side of the fixing part corresponding to the support plate, and a gap is formed between adjacent L-shaped baffles. The end of the support plate corresponding to the L-shaped baffle is located in the gap. The baffle assembly is a one-piece stamped sheet metal sheet. When the electrode plate flies forward and touches the vertical plate of the L-shaped baffle, the L-shaped baffle 612 deforms slightly to buffer the impact and effectively prevent the electrode plate from being damaged or deformed.

[0029] The top of the base plate 611 has slots 611a corresponding to the support plates. The protrusions 612a at the bottom of the support plates 612 are inserted into these slots to ensure all support plates remain parallel. The base plate has strip holes 611b on both sides of the slots. Screw holes for fixing the support plates to the base plate are located at the bottom. Bolts pass through these strip holes to fix the support plates to the base plate. The protrusions can be moved along the slots to adjust the spacing between the support plates.

[0030] Guide components are installed at the ends of both the first and second conveyor lines. The guide components include a pressure roller 461 and several smooth round wheels 462. The smooth round wheels are mounted on the sprockets of the conveyor components, and the smooth round wheels and sprockets are fixedly connected by welding. The pressure roller is located above the smooth round wheels. Connecting plates at both ends of the pressure roller are connected to a support plate 410 via rotating shafts. A first pin is installed on the connecting plate, and a second pin is installed on the support plate. The first and second pins are connected by a tension spring 463. When the electrode plate passes under the pressure roller, the pressure roller is slightly lifted upwards. The electrode plate's speed is reduced when passing between the pressure roller and the smooth round wheels, effectively preventing damage to the electrode plate due to high-speed impact with the L-shaped baffle.

[0031] The front end of the vacuum belt conveyor extends above the surface drying kiln conveyor line. The electrode plates conveyed below the vacuum belt conveyor are attracted by its lower surface. The perforated belt drive within the vacuum belt conveyor transports the electrode plates above the first conveyor line. The first shuttle valve assembly in the first chamber breaks the vacuum, allowing the electrode plates to automatically fall onto the first conveyor line. The first conveyor line transports the electrode plates one by one to the plate-collecting device. After the current plate-collecting device completes the stacking and collecting of one electrode plate assembly, the material support assembly descends below the first conveyor unit, and the electrode plate assembly automatically transfers to the first conveyor unit. The moment the plate-collecting device completes collecting, the first conveyor line stops operating. The first shuttle valve assembly in the first chamber creates a negative pressure in the chamber, allowing the electrode plates attracted below the vacuum belt conveyor to be transported backward through the first chamber to the top of the second conveyor line. Since no negative pressure is created in the second chamber, the electrode plates automatically fall onto the second conveyor line after reaching the bottom of the second chamber. The second conveyor line transports the electrode plates one by one to the plate-collecting device. After the current plate-collecting device completes the stacking and collecting of one electrode plate assembly, the material support assembly descends below the first conveyor unit, and the electrode plate assembly is automatically transferred to the first conveyor unit. The moment the plate-collecting device completes collecting the plates, the second conveyor line stops operating, and the first shuttle valve assembly in the first chamber breaks the vacuum in that chamber.

[0032] In this embodiment, the first and second conveyor lines are set up as transfer points between the vacuum belt line and the plate take-up device. The speed of the plate after transmission is adjusted by the conveyor lines, eliminating the occurrence of adhesion.

[0033] A sorting device 700 is provided at the end of the first conveying unit. The electrode assembly is conveyed from the first conveying unit into the sorting device, where it is tapped to align the edges of all the electrode plates. A second conveying unit 800 is provided on one side of the sorting device opposite to the first conveying unit. The sorted electrode assembly is transported to the subsequent process by the second conveying unit. In this embodiment, a sorting table 900 is provided beside and at the end of the second conveying unit. The operator takes the electrode assembly from the second conveying unit and places it on the sorting table to await subsequent operations.

[0034] The sorting device 700 includes a bracket 710 disposed at the top of the rear upright plate 801 of the second conveying unit 800. A rotating shaft 720 is disposed at corresponding intervals on the bracket, and a motor 730 disposed on one side of the bracket drives the rotating shaft to rotate. A square rotating part 740 is mounted on the rotating shaft. The rotating part includes a first side plate 741, a second side plate 742, a third side plate 743, and a fourth side plate 744 connected end-to-end. Mounting seats 750 are disposed on the first and third side plates. A receiving device including a carrier plate 761 and a vibrator 762 is mounted on the rotating part. The carrier plate 761 is connected to the mounting seat via a rubber pad 763. The vibrator is mounted between the carrier plate and the mounting seat, and the output shaft of the vibrator is connected to the carrier plate. Limiting plates 770 extending to both sides of the mounting seat are disposed on the second and fourth side plates, forming a receiving space for the electrode assembly between the limiting plates and the carrier plate. The sorting unit has two opposing receiving spaces. When the electrode assembly is received from the first conveying unit in one receiving space, the electrode assembly in the other receiving space is transferred to the second conveying unit. The sorting unit has the function of synchronous feeding and unloading.

[0035] The sorting device 700 also includes a tapping mechanism 780 located above the rotating part. The tapping mechanism includes a guide rod 781 whose end is connected to the bracket 710, and two tapping plates 782 sleeved on the guide rod. A third cylinder 783 mounted on the bracket drives the two tapping plates to move towards or away from each other. When the motor drives the rotating part to rotate 90°, so that one of the carrier plates faces upward, the electrode assembly is exactly between the two tapping plates. The vibrator works to make the carrier plate shake continuously, loosening the adsorbed and adhered electrode plates. The third cylinder 783 drives the two tapping plates to reciprocate several times to flatten the electrode assembly.

[0036] like Figure 1 As shown, the electrode assembly includes a first surface A1, a second surface A2, a third surface A3, and a fourth surface A4. When the electrode assembly is formed in the plate-collecting device, the first surface A1 of the electrode assembly contacts an L-shaped baffle. The limiting and blocking function of the L-shaped baffle initially flattens the first surface A1 and the third surface A3 of the electrode assembly. The electrode assembly enters the finishing unit, where a rotating part drives the electrode assembly to rotate 90° so that the third surface A3 faces upwards. A vibrator drives the carrier plate to continuously shake, loosening the electrode assembly. Under the action of gravity, the first surface A1 and the third surface A3 of the electrode assembly are further flattened. Simultaneously, a striking plate continuously and repeatedly strikes the second surface A2 and the fourth surface A4 of the electrode assembly, flattening these two surfaces.

[0037] The width of the vacuum conveyor belt is smaller than the width of the electrode plate. A proximity switch or photoelectric sensor is installed on the side of the vacuum conveyor belt. If the electrode plate is damaged or incomplete, the signal duration of the proximity switch 380 or photoelectric sensor will be incomplete, and the equipment's PLC control system can identify this electrode plate as NG (Not Found). Figure 2As shown, a third chamber, independent and not connected to the main chamber of the vacuum conveyor belt, is located on the side of the first chamber relative to the second chamber. A second shuttle valve assembly 390 connected to the third chamber is installed on the vacuum conveyor belt. The second shuttle valve assembly is configured to create a vacuum negative pressure and break the vacuum in the third chamber. When the PLC control system determines that the current electrode plate is NG, the second shuttle valve assembly breaks the vacuum in the third chamber, and the electrode plate automatically falls into the NG tray 1000 below.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
