Description

Technical Field

[0001] The present invention belongs to the technical field of battery production, and particularly relates to a palletizing and packaging line for lead-acid battery packs. Background Art

[0002] A storage battery is an important electric energy carrier and is widely used in fields such as automobiles, household appliances, and electronic devices. With the development of the green economy, the demand for storage batteries is increasing year by year. After the production of storage battery products is completed, boxing and packaging are required at the end. Operations such as opening boxes, placing foam, and bagging all need to be completed manually. These operations are usually concentrated at the packing machine and are completed by the cooperation of two to three people.

[0003] With the gradual increase in the demand for production efficiency, there are often situations where employees cannot keep up with the production rhythm due to random factors, and the operation stations of employees move backward along with the products towards the rear of the production line. As the packing operation is the last manual operation process on the production line, material jams often occur at the packing operation because employees cannot keep up with the production rhythm. At this time, only the emergency stop button of the production line can be pressed to pause the entire production line. This way of pausing will cause all the workers and equipment on the entire line to be in a paused state. After restarting, it is difficult for the production line to immediately reach the normal production efficiency, resulting in serious losses in the production line's production capacity. Moreover, the pause causes greater wear and tear on the production line equipment and increases the incidence of equipment failures. Summary of the Invention

[0004] The purpose of the present invention is to provide a palletizing and packaging line for lead-acid battery packs. By setting a packing buffer line body in front of the case sealer for packing the battery sets into the packing boxes, the packing buffer line body leaves sufficient buffer time for employees to operate, solving the problem that in the existing production process, when employees' operations cannot keep up with the rhythm, the production line needs to be paused, resulting in serious losses in the production line's production capacity.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a palletizing and packaging line for lead-acid battery packs. Along the battery conveying direction, it includes a packing buffer line body for packing the battery sets into the packing boxes, a case sealer arranged behind the packing buffer line body, a strapping machine arranged behind the case sealer for winding packing straps around the boxes, a blanking line body arranged behind the strapping machine, and a palletizer arranged on one side of the blanking line body.

[0007] As a preferred technical solution of the present invention, it further includes a labeling and inspection line body arranged in front of the packing buffer line body for pasting barcodes on the battery shell and inspecting whether there are appearance defects such as scratches on the battery shell.

[0008] As a preferred technical solution of the present invention, a bracket is fixedly installed on one side of the label pasting and detecting line body, and a plurality of material boxes are fixedly arranged on the bracket, which is convenient for placing barcodes of different types in different material boxes. A box cover is matched with the material box, and a strip-shaped opening is arranged at one end of the box cover close to the label pasting and detecting line body, which is convenient for employees to pull out the barcode from the strip-shaped opening for operation.

[0009] As a preferred technical solution of the present invention, it further includes a weighing line body arranged in front of the label pasting and detecting line body for detecting whether the weight of the battery is qualified to judge whether the acid liquid addition amount in the battery meets the standard.

[0010] As a preferred technical solution of the present invention, a calibration console for calibrating the weighing line body is arranged on one side of the weighing line body, and a calibration scale is placed on the calibration console to improve the measurement accuracy of the weighing line body.

[0011] As a preferred technical solution of the present invention, a defective product transfer line body is arranged on the other side of the weighing line body, and rollers are arranged at the bottom of the defective product transfer line body, which is convenient for transferring defective products to the repair area for rework.

[0012] As a preferred technical solution of the present invention, the palletizer includes a clamping mechanism and a manipulator for driving the clamping mechanism to move.

[0013] As a preferred technical solution of the present invention, the clamping mechanism includes a support rod and two clamping plate assemblies symmetrically arranged on the support rod. The clamping plate assembly includes a clamping plate and a telescopic cylinder for driving the clamping plate to move. The two clamping plates are perpendicular to the support rod, and one ends of the two clamping plates are slidably connected to the lower surface of the support rod.

[0014] As a preferred technical solution of the present invention, a slide rail is fixedly installed on the lower surface of the support rod, and a slider is fixedly installed at the upper end of the clamping plate. The slider is slidably connected to the slide rail.

[0015] As a preferred technical solution of the present invention, the clamping plate assembly further includes a support block, a first driving block and a second driving block. The support block is fixedly installed at both ends of the support rod. One end of the first driving block is hinged to one side surface of the clamping plate close to the support block. The other end of the first driving block is hinged to one end of the second driving block. The other end of the second driving block is hinged to the support block. Connecting pieces for fixing the telescopic cylinder are fixedly connected to both ends of the support rod. One end of the telescopic cylinder is hinged to the connecting piece, and the other end of the telescopic cylinder is hinged to the hinged part of the first driving block and the second driving block. The telescopic cylinder is perpendicular to the support rod.

[0016] The present invention has the following beneficial effects:

[0017] 1. The present invention provides a packing buffer line for packing battery sets into packing boxes in front of the case sealer. When employees cannot keep up with the line rhythm, the packing buffer line leaves sufficient buffer time for employees to operate, avoiding pausing the entire production line, and thus ensuring the production efficiency of the production line.

[0018] 2. The present invention provides a palletizer, which includes a clamping mechanism and a manipulator for driving the clamping mechanism to move. The clamping mechanism includes a support rod and two clamping plate assemblies symmetrically arranged on the support rod. Each clamping plate assembly includes a clamping plate, a telescopic cylinder, a support block, a first driving block, and a second driving block. When it is necessary to clamp a battery pack, the telescopic cylinder extends, pushing the first driving block, the second driving block, and the support block to gradually tend to be in a straight line. The interaction force between the first driving block, the second driving block, and the support block amplifies the telescopic force of the telescopic cylinder, avoiding directly driving the clamping plate to move by the telescopic cylinder to clamp the battery pack, which may result in insufficient clamping force and cause the battery pack to fall and be damaged, and ensuring the qualification rate of the products offline.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0035] Embodiment 1

[0036] Please refer to Figure 1 - Figure 2As shown in the figure, this embodiment provides a palletizing and packaging line for lead-acid battery packs, which sequentially includes, along the conveying direction of the battery packs: a packing buffer line body 100 for packing the battery sets into packing boxes; a case sealer 200 arranged behind the packing buffer line body 100; a strapping machine 300 arranged behind the case sealer 200 for winding packing straps around the boxes; a blanking line body 400 arranged behind the strapping machine 300; and a palletizer 500 arranged on one side of the blanking line body 400. During operation, the finished batteries are conveyed to the packing buffer line body 100, and operations such as opening the box, placing foam, bagging, and placing accessories are performed on the motors on the packing buffer line body 100. Subsequently, the batteries are conveyed in the packing boxes to the case sealer 200 for case sealing; then, the packaged packing boxes are conveyed to the strapping machine 300 for winding packing straps. Finally, the packed battery packs are conveyed to the blanking line body 400, and the palletizer 500 stacks the battery packs. Among them, the packing buffer line body 100, the case sealer 200, the strapping machine 300, and the blanking line body 400 are all designed based on power roller conveyor lines.

[0037] Please refer to Figure 3 - Figure 6 As shown in the figure, the palletizer 500 includes a clamping mechanism and a manipulator 1 for driving the clamping mechanism to move. The clamping mechanism includes a support rod 2 and two clamping plate assemblies symmetrically arranged on the support rod. The clamping plate assembly includes a clamping plate 3 and a telescopic cylinder 4 for driving the clamping plate 3 to move. The telescopic cylinder 4 uses a pneumatic cylinder. The two clamping plates 3 are perpendicularly arranged with the support rod 2. A slide rail 201 is fixedly installed on the lower surface of the support rod 2, and a slider 301 is fixedly installed at the upper end of the clamping plate 3. The slider 301 is slidably connected with the slide rail 201, enabling the two clamping plates 3 to slide towards each other along the support rod for clamping or loosening the battery packs.

[0038] In addition, to improve the clamping stability between the two clamping plates, the clamping plate assembly is also designed with support blocks 5, a first driving block 6, and a second driving block 7. The support blocks 5 are fixedly installed at both ends of the support rod 2. One end of the first driving block 6 is hinged to the side surface of the clamping plate 3 close to the support block 5. The other end of the first driving block 6 is hinged to one end of the second driving block 7. The other end of the second driving block 7 is hinged to the support block 5. Connecting pieces 8 for fixing the telescopic cylinder 4 are fixedly connected to both ends of the support rod 2. One end of the telescopic cylinder 4 is hinged to the connecting piece 8, and the other end of the telescopic cylinder 4 is hinged to the hinged part of the first driving block 6 and the second driving block 7, so that the telescopic cylinder 4 is perpendicularly arranged with the support rod 2. When it is necessary to clamp the battery pack, the telescopic cylinder 4 extends, pushing the first driving block 6, the second driving block 7, and the support block 5 to gradually tend to be in a straight line. Through the mutual acting forces between the first driving block 6, the second driving block 7, and the support block 5, the telescopic force of the telescopic cylinder 4 is amplified, thus avoiding directly driving the clamping plate to move and clamp the battery pack by the telescopic cylinder, resulting in insufficient clamping force and causing the battery pack to fall and be damaged, and ensuring the qualified rate of the products offline.

[0039] Embodiment Two

[0040] Based on Embodiment 1, the difference in Embodiment 2 is as follows:

[0041] Please refer to Figure 7 - Figure 8 As shown, a labeling and inspection line body 600 is further provided in front of the packing buffer line body 100, which is used to label the qualified batteries and check whether there are defects such as scratches on the appearance of the batteries, so as to ensure the first-pass qualification rate of the batteries when they come off the production line.

[0042] In addition, for the convenience of the employees' labeling operations, a bracket 9 is fixedly installed on one side of the labeling and inspection line body 600. A plurality of material boxes 10 for placing barcodes are fixedly arranged on the bracket 9. The number of material boxes is set according to the types of barcodes to be pasted, and labels are pasted on the material boxes to avoid confusion in taking. A box cover 11 is matched with the material box 10. The box cover 11 and the material box 10 can be in a snap-fit or hinged form, which is convenient for opening and putting barcodes into the material box. The box cover 11 is provided with a strip-shaped opening 1101 at one end close to the labeling and inspection line body 600, which is convenient for the employees to pull out the barcodes from the strip-shaped opening 1101 according to the taking requirements, thereby improving the operation efficiency of the barcode pasting process.

[0043] Embodiment 3

[0044] Based on Embodiment 2, the difference in Embodiment 3 is as follows:

[0045] Please refer to Figure 9 As shown, also to ensure the qualification rate of the products when they come off the production line and avoid the need to rework and unpack the packed batteries, a weighing line body 700 is provided in front of the labeling and inspection line body 600. The weighing line body 700 is used to detect whether the weight of the batteries is qualified, so as to judge whether the amount of acid solution added to the batteries meets the standard. The main working principle of the weighing line body 700 is as follows: when the material is placed on the line body, the polyurethane elastomer will deform due to the working pressure of the material. The deformation of the polyurethane elastomer causes the resistance strain gauges on its surface to deform accordingly. The deformation of the resistance strain gauges causes their resistance values to change. Then, the increased or decreased value of the resistance is converted into an electronic signal through the detection circuit, and thus the weight of the object can be displayed.

[0046] A calibration console 12 for calibrating the weighing line body is also provided on one side of the weighing line body 700. A calibration scale 13 is placed on the calibration console 12. If the weighing line body 700 determines that the battery weight is unqualified, the unqualified battery can be manually measured again, and the weighing line body 700 can be calibrated in combination with the measurement results to ensure the measurement accuracy. On the other side of the weighing line body 700, there is a defective product transfer line body 800. The bottom of the defective product transfer line body 800 is provided with rollers. The unqualified battery cases are temporarily stored on the defective product transfer line body 800 and are uniformly transferred to the repair area for repair.

[0047] In the description of this specification, the descriptions referring to the terms "one embodiment", "example", "specific example", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.
