Description

Technical Field

[0001] This invention relates to the field of cathode copper stripping devices, and more specifically, to a cathode copper stripping device and method. Background Technology

[0002] The original four-blade simultaneous one-time peeling method, because four peeling blades act on both sides of the cathode copper plate at the same time, is prone to incomplete peeling in some areas, especially for high-hardness or thick metals, due to the tight adhesion between the cathode metal and the initial bonding points of the cathode copper plate. This results in incomplete peeling of some areas, requiring secondary processing of residual metal and increasing process costs. Secondly, different cathode metals, such as copper, nickel, and zinc, have significant differences in physical properties, with varying hardness and brittleness. When the four blades apply force simultaneously, the more brittle zinc metal is prone to cracking or shattering due to uneven instantaneous force, affecting product integrity. Existing equipment is ill-suited for stripping various types of cathode metals. The original four-blade synchronous method, with its fixed stripping force and speed, cannot adjust the initial stripping for different metals. Changing the metal type requires readjusting the blade parameters, which is time-consuming and makes continuous operation difficult. With all four blades acting on both sides of the cathode copper plate simultaneously, if the cathode copper plate itself has slight deformation or uneven thickness, lateral forces are easily generated during synchronous stripping, causing the cathode copper plate to bend or warp, affecting its reusability and increasing the cathode copper plate wear rate.

[0003] Therefore, a simple and effective solution is needed to address the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a cathode copper stripping device that can simplify the production process and has high production efficiency, low cost and good reliability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a cathode copper stripping device, comprising a frame, two cathode copper plate conveyors for conveying unstripped cathode copper plates and stripped cathode copper plates respectively, a spraying device mounted on one of the cathode copper plate conveyors, and a transfer clamping mechanism mounted on both cathode copper plate conveyors; characterized in that: It also includes a peeling device, a vibratory hammer assembly, a guide and positioning assembly used in conjunction with the vibratory hammer assembly, and a first screw drive mechanism for driving the peeling device and the vibratory hammer assembly to move horizontally and laterally, all of which are fixedly mounted on the frame; the frame is also provided with a buffer receiving assembly and the palletizing device. The stripping device includes two sets of stripping blades capable of bidirectional synchronous movement, a second lead screw transmission mechanism for driving the stripping blades to move bidirectional synchronously, and a third lead screw transmission mechanism for driving the stripping blades to move vertically along the cathode copper plate; the stripping device is connected to the frame via a connecting frame. The vibratory hammer assembly includes a fixed plate connected to the connecting frame, a first drive cylinder connected to the fixed plate via a hinge seat, and a hammer head hinged to the telescopic rod of the first drive cylinder. The guiding and positioning assembly includes a U-shaped frame located on the frame, a second drive cylinder connected by a fixed seat, and a guide frame hinged to the telescopic rod of the second drive cylinder. The guide frame is hinged to the connecting seat fixed to one side of the fixed base; a guide plate connected to the connecting seat is also provided below the connecting seat.

[0006] In one embodiment, the cathode copper plate conveyor includes a positioning frame, a drive device, multiple plate-laying chains, a drive shaft, and several gears. The gears are respectively mounted on the positioning frame and the drive shaft. The drive device is used to drive the drive shaft to rotate, and the plate-laying chains mesh with the several gears.

[0007] In one embodiment, the spraying device includes a spray chamber, a plurality of spray pipes located in the spray chamber, nozzles disposed on the spray pipes, and a water pump.

[0008] In one embodiment, the transfer clamping mechanism includes a lifting mechanism, a robotic arm mechanism for gripping the cathode, and a support frame; the robotic arm mechanism is located at the bottom of the lifting mechanism. The robotic arm mechanism includes a hydraulic cylinder support frame fixed to one end of the positioning support, a transfer cylinder fixed at an inclination on the hydraulic cylinder support frame, a rotating shaft rotatably connected to the piston rod of the transfer cylinder, hooks fixed at both ends of the rotating shaft, and bearing seats symmetrically arranged at both ends of the rotating shaft and fixedly connected to the positioning support. The control terminal of the transfer cylinder is electrically connected to the shaft encoder. The piston rod of the transfer cylinder is connected to the rotating shaft via a hinge seat fixed in the middle of the rotating shaft; The lifting mechanism includes lifting cylinders fixed on the support frame, lifting shafts symmetrically arranged at both ends of the lifting cylinders and passing through the support frame, and guide bearing seats sleeved on the lifting shafts; the piston rod of the lifting cylinder extends downward through the support frame and is fixedly connected to the positioning support.

[0009] In one embodiment, the outer side of the support frame is provided with an elastic positioning mechanism, which is used for positioning the stripped cathode copper plate during lifting and transfer. The elastic positioning mechanism includes a base plate fixedly connected to the support frame, a positioning slide fixedly disposed on the positioning slide, a slide rail slidably connected to the positioning slide, and a spring positioning part for elastically positioning the slide rail.

[0010] In one embodiment, the peeling blade includes a peeling blade head and a connecting portion integrally formed with the peeling blade head; the cross-section of the peeling blade head is triangular.

[0011] In one embodiment, in order to achieve buffering, straightening and stacking of the stripped finished cathode copper plate, the buffer receiving assembly works in conjunction with the stacking device. The buffer receiving assembly includes an inclined slide rail and a pair of openable and closable receiving plates located at the end of the slide rail; the receiving plates have a left-right symmetrical structure and are driven to open and close by a cylinder or hydraulic cylinder. The stacking device includes a pusher mechanism, which is used to push the cathode copper plate that has slid onto the receiving plate to a predetermined position, and to push the stack of metal plates below to align after the receiving plate is opened. In one embodiment, a shock absorber is also provided on the slide to reduce the impact when the cathode copper plate slides down.

[0012] This embodiment also provides a stripping method using a cathode copper stripping device, including the following steps: S1: The unpeeled cathode copper plate is transported by the first cathode copper plate conveyor and the unpeeled cathode copper plate is sprayed and cleaned by the spraying device. S2: Activate the transfer clamping mechanism to clamp the unpeeled cathode copper plate after spray cleaning, rotate it 90° and transfer it to the preset peeling operation area, and use the transfer clamping mechanism and the guide positioning component to coordinate the positioning of the unpeeled cathode copper plate. S3: Start the vibration hammering assembly, drive the vibration hammering assembly to move laterally to the working surface of the unpeeled cathode copper plate through the first lead screw transmission mechanism, and hammer the unpeeled cathode copper plate. The hammering time is controlled at 5-10 seconds. After the hammering is completed, the vibration hammering assembly is reset. S4: Start the stripping device, drive the two sets of stripping blades to move synchronously in both directions through the second lead screw transmission mechanism to cut into the unstripped cathode copper plate, and drive the stripping blades to perform staged stripping and cutting along the vertical direction of the cathode copper plate by the third lead screw transmission mechanism, and sequentially complete the stripping of the first preset size A1, the second preset size A2 and the third preset size A3, and finally achieve the complete stripping of the cathode copper plate. S5: Restart the transfer clamping mechanism to transfer the stripped cathode copper plate to the second cathode copper plate conveyor, and the second cathode copper plate conveyor will output it.

[0013] The beneficial effects of this invention are as follows: In this invention, a cathode copper stripping device is provided. After the transfer clamping mechanism 4 delivers the cathode copper plate to the stripping station, the second drive cylinder 72 of the guide positioning assembly 7 drives the guide frame 73 to move, stably fixing the copper plate within the U-shaped frame 71. Subsequently, the first screw transmission mechanism 8 drives the entire vibratory hammering assembly 6 to move laterally to the working surface of the copper plate. The first drive cylinder 62 then starts, and its telescopic rod drives the hammer head 63 to perform rapid hammering within 5-10 seconds. The vibration wave generated by the hammering propagates along the plate surface, generating shear stress at the metal bonding interface, thereby achieving pre-loosening. Directly using a stripping knife for one-time stripping, if the initial bonding is too tight, will lead to stress concentration, easily causing incomplete stripping or brittle metal plate breakage. This invention uses a method of loosening before stripping. Although the impact force applied by the vibratory hammering is insufficient to cause macroscopic separation, its energy is sufficient to break the van der Waals forces or tiny metallurgical bonding points between metals at the microscopic level, equivalent to pre-creating countless tiny cracks. Therefore, when the subsequent peeling blade intervenes, it only needs to overcome the residual adhesion, not the original, strong bonding force; this makes the initial peeling more efficient and convenient, greatly reducing the risk of peeling failure and metal residue; this pretreatment method avoids plate cracking caused by instantaneous stress concentration, improving yield and product integrity. It ensures streamlined operation in the production process, saves coordination time between processes, achieves high production efficiency, ensures stable production at low cost, and has good reliability.

Detailed Implementation

[0014] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Please see Figures 1 to 16 As shown, it includes a frame 1, two cathode copper plate conveyors 2 for conveying unstripped cathode copper plates and for conveying stripped cathode copper plates respectively, a spraying device 3 installed on one of the cathode copper plate conveyors 2, and a transfer clamping mechanism 4 installed on the two cathode copper plate conveyors 2. It also includes a peeling device 5, a vibratory hammer assembly 6, a guide and positioning assembly 7 used in conjunction with the vibratory hammer assembly 6, and a first screw drive mechanism 8 for driving the peeling device 5 and the vibratory hammer assembly 6 to move horizontally and laterally, all fixedly mounted on the frame 1. The frame 1 is also equipped with a buffer receiving assembly 9 and a palletizing device 10. Its internal structure has a layered design for classifying and neatly stacking the peeled finished metal sheets. Specifically, after the finished sheets are conveyed to the palletizing device, they are placed on designated layers via internal lifting or sorting mechanisms. This facilitates subsequent management, counting, and transfer of finished products of different batches and specifications, achieving automation and standardization of the production process and further improving overall production efficiency.

[0016] The stripping device 5 includes two sets of stripping blades 51 capable of bidirectional synchronous movement, a second screw transmission mechanism 52 for driving the stripping blades 51 to move bidirectional synchronously, and a third screw transmission mechanism 53 for driving the stripping blades 51 to move vertically along the cathode copper plate; the stripping device 5 is connected to the frame 1 via a connecting frame 11. The vibratory hammer assembly 6 includes a fixed plate 61 connected to the connecting frame 11, a first drive cylinder 62 connected to the fixed plate 61 via a hinge seat 11, and a hammer head 63 hinged to the telescopic rod of the first drive cylinder 62. The guide positioning assembly 7 includes a U-shaped frame 71 located on the frame 1, a second drive cylinder 72 connected by a fixed seat 13, and a guide frame 73 hinged to the telescopic rod of the second drive cylinder 72. The guide frame 73 is hinged to the connecting seat 13 which is fixed to one side of the fixed seat 12; a guide plate 14 connected to the connecting seat 13 is also provided below the connecting seat 13.

[0017] Specifically, in the above implementation, the unpeeled cathode copper plate is fed in by a cathode copper plate conveyor 2, and after being sprayed and cleaned, it is gripped, rotated, and transported to the peeling station by the transfer clamping mechanism 4. At the peeling station, the guide positioning component 7 first precisely positions the copper plate, then the vibration hammering component 6 pre-treats the copper plate, and then the peeling device 5 performs staged peeling; after peeling, the transfer clamping mechanism 4 transfers the peeled copper plate and the starting electrode sheet (i.e., the cathode copper plate) to another cathode copper plate conveyor, and finally to the buffer receiving group 9 and the stacking device 10; the entire process is uniformly scheduled by the central control system PLC, and each component operates in coordination according to the preset program. The function of the guide positioning component 7 is to fix the position of the cathode copper plate before hammering and peeling, to prevent it from shifting or vibrating under force, and to provide a stable reference for subsequent processes. The function of the vibration hammering component 6 is not to directly peel, but to pre-break the initial bonding force between the cathode and anode metals through high-frequency, controllable hammering force before the peeling blade intervenes, especially in tightly bonded areas such as edges and corners. It includes two sets of bidirectional synchronously moving stripping blades, a second lead screw drive mechanism that drives them to cut synchronously, and a third lead screw drive mechanism that drives them to move vertically. The stripping blade head has a triangular cross-section. Its function is to achieve a staged, gradual stripping method. The second lead screw drive mechanism controls the two sets of stripping blades to cut synchronously into the edge of the cathode copper plate from both sides, ensuring balanced force. The third lead screw drive mechanism controls the stripping blade to move upward, performing the stripping. The triangular blade head design, utilizing its wedge-shaped structure, enables separation with minimal resistance during cutting.

[0018] More specifically, after the transfer clamping mechanism 4 delivers the cathode copper plate to the stripping station, the second drive cylinder 72 of the guide positioning assembly 7 drives the guide frame 73 to move, stably fixing the copper plate within the U-shaped frame 71. Subsequently, the first lead screw transmission mechanism 8 drives the entire vibratory hammering assembly 6 to move laterally to the working surface of the copper plate. The first drive cylinder 62 then starts, and its telescopic rod drives the hammer head 63 to perform 4-6 rapid hammer blows within 5-10 seconds. The vibration waves generated by the hammering propagate along the plate surface, generating shear stress at the metal bonding interface, thereby achieving pre-loosening. Directly using a stripping knife for one-time stripping, if the initial bonding is too tight, will lead to stress concentration, easily causing incomplete stripping or brittle metal plate breakage. This invention uses a method of loosening before stripping. Although the impact force applied by the vibratory hammering is insufficient to cause macroscopic separation, its energy is sufficient to break the van der Waals forces or tiny metallurgical bonding points between metals at the microscopic level, equivalent to pre-creating countless tiny cracks. Therefore, when the subsequent peeling blade intervenes, it only needs to overcome the residual adhesion, rather than the original, strong bonding force; making the initial peeling more efficient and convenient, greatly reducing the risk of peeling failure and metal residue; this pretreatment method avoids plate cracking caused by instantaneous stress concentration, improving the yield and product integrity.

[0019] Preferably, the cathode copper plate conveyor 2 includes a positioning frame 21, a drive unit 22, multiple plate-laying chains 23, a drive shaft 24, and several gears 25. The gears 25 are respectively mounted on the positioning frame 21 and the drive shaft 24. The drive unit 22 drives the drive shaft 24 to rotate, and the plate-laying chains 23 mesh with the gears 25. This chain and gear meshing transmission provides stable and reliable linear conveying of the plates. Specifically, the drive unit drives the drive shaft and gears to rotate, thereby driving the plate-laying chains to circulate and carry the cathode copper plates forward. The advantages are that the chain drive structure is simple, easy to maintain, and has a strong load-bearing capacity, adapting to the heavy-load and continuous operation requirements of industrial environments and ensuring smooth connection between upstream and downstream processes.

[0020] Preferably, the spraying device 3 includes a spray chamber 31, multiple spray pipes 32 located in the spray chamber 31, nozzles 33 mounted on the spray pipes 32, and a water pump 34. Specifically, the cathode copper plate is cleaned before peeling. Water is pressurized by the water pump and sent to the spray pipes, forming a high-pressure water mist through the nozzles to thoroughly rinse the surface of the cathode copper plate. Using this spraying method effectively removes electrolyte residue, dust, and other impurities from the surface of the plate, preventing impurities from scratching the plate or affecting the normal operation of the peeling blade during subsequent peeling, which is a prerequisite for ensuring high-quality peeling.

[0021] Preferably, the transfer and clamping mechanism 4 includes a lifting mechanism 41, a robotic arm mechanism 42 for gripping the cathode, and a support frame 43; the robotic arm mechanism 42 is located at the bottom of the lifting mechanism 41. The robotic arm mechanism 42 includes a cylinder support frame 421 fixed to one end of the positioning support 15, a transfer cylinder 422 tilted and fixed on the cylinder support frame 421, a rotating shaft 423 rotatably connected to the piston rod of the transfer cylinder 422, hooks 424 fixedly disposed at both ends of the rotating shaft 423, and bearing seats 425 symmetrically disposed at both ends of the rotating shaft 423 and fixedly connected to the positioning support 15; The control terminal of the transfer cylinder 422 is electrically connected to the shaft encoder; The piston rod of the transfer cylinder 422 is connected to the rotating shaft 423 via a hinge seat 16 fixed in the middle of the rotating shaft 423; The lifting mechanism 41 includes a lifting cylinder 411 fixed on the support frame 43, a lifting shaft 412 symmetrically arranged at both ends of the lifting cylinder 411 and passing through the support frame 43, and a guide bearing seat 413 sleeved on the lifting shaft 412; the piston rod of the lifting cylinder 411 extends downward through the support frame 43 and is fixedly connected to the positioning support 15.

[0022] Specifically, it employs a combination of a lifting cylinder and a transfer cylinder, with rotation controlled by a shaft encoder. Its function is to grip, rotate, lift, and transfer the cathode copper plate between the conveyor and the stripping station. The lifting cylinder controls the overall vertical movement, while the transfer cylinder drives the rotating shaft via its piston rod, achieving the rotating gripping / releasing action of the hook. This application achieves rapid, stable, and high-load operation through the combination of pneumatic and hydraulic systems. The introduction of the shaft encoder ensures precise control of the rotation angle, guaranteeing that the plate can be accurately fed into and out of the stripping station.

[0023] Preferably, the outer side of the support frame 43 is provided with an elastic positioning mechanism 16, which is used for positioning when the stripped cathode copper plate is lifted and transferred. The elastic positioning mechanism 16 includes a base plate 161 fixedly connected to the support frame 43, a positioning slide 162 fixedly provided thereon, a slide rail 163 slidably connected to the positioning slide 162, and a spring positioning part 164 for elastically positioning the slide rail 163.

[0024] Specifically, the elastic positioning mechanism 16 is used to position the stripped cathode copper plate during the lifting and transfer process. Through the coordinated action of the slide rail 163 and the spring positioning part 164 that elastically positions the slide rail 163, the elastic positioning mechanism 16 can provide a certain buffer and absorb vibration when clamping the copper plate, while ensuring that the copper plate is stably fixed in the predetermined position, thereby preventing shaking or displacement during the transfer process, ensuring accurate docking of subsequent processes and stable operation of the equipment.

[0025] Preferably, the stripping blade 51 includes a stripping blade head 511 and a connecting portion 512 integrally formed with the stripping blade head 511; the cross-section of the stripping blade head 511 is triangular. It is understood that the integrally formed connecting portion 512 design enhances the structural strength and rigidity of the stripping blade 51, making it less prone to breakage or deformation under stripping force, thus extending its service life. The triangular blade head forms a wedge-shaped structure. The core advantage of this design is that when the blade cuts into the gap between the cathode copper plate and the starting plate, it can generate an efficient separation force with minimal resistance. The wedge-shaped surface can smoothly convert the force into a pushing force on the metal plates on both sides, achieving gradual and low-damage stripping, effectively avoiding deformation or breakage of the copper plate caused by violent tearing, improving the yield and the reusable service life of the starting plate.

[0026] Preferably, in order to achieve buffering, straightening and stacking of the stripped finished cathode copper plates, the buffer receiving assembly 9 and the stacking device 10 work together. The buffer receiving assembly 9 includes an inclined slide 91 and a pair of openable receiving plates 92 located at the end of the slide 91; the receiving plates 92 have a left-right symmetrical structure and are driven to open and close by a cylinder or a hydraulic cylinder. The stacking device 10 includes a pusher mechanism 101, which is used to push the cathode copper plate that has slid onto the receiving plate 92 to a predetermined position, and to push the metal plate stack below to align after the receiving plate 92 is opened. Preferably, in order to reduce the impact when the cathode copper plate slides down, a shock absorber 17 is also provided on the slide 91.

[0027] Specifically, the buffer receiving assembly 9 and the stacking device 10 work together to buffer, receive, organize, and stack the stripped finished cathode copper plates. The stripped metal plates are conveyed to the buffer receiving assembly 9, which includes an inclined slide. The metal plates slide along the slide onto a pair of symmetrically arranged receiving plates at its end. To reduce the impact force during the sliding process, shock absorbers 17 can be installed on the slide. Once the metal plate is stable on the receiving plates, the pushing mechanism of the stacking device 10 is activated, pushing the metal plate forward horizontally to accurately position it. Subsequently, the receiving plates, driven by a cylinder or hydraulic cylinder, open to both sides, and the metal plate falls vertically into the stacking area below. Each time a metal plate falls, the pushing mechanism can be activated again to push the stacked metal plates, ensuring the edges of the entire stack are neat. The stacking area of ​​the palletizing device 10 has reserved space for forklift operation below. When the metal plates are stacked to the predetermined height, the forklift can easily enter and carry away the entire stack of finished products, realizing the automation and efficiency of the collection, palletizing and transfer process.

[0028] This embodiment also provides a stripping method using a cathode copper stripping device, including the following steps: S1: The unpeeled cathode copper plates are transported by the first cathode copper plate conveyor and sprayed and cleaned by the spraying device. S2: Start the transfer clamping mechanism to clamp the unpeeled cathode copper plate after spray cleaning, rotate it 90° and transfer it to the preset peeling operation area, and use the transfer clamping mechanism and guide positioning components to coordinate the positioning of the unpeeled cathode copper plate. S3: Start the vibration hammer assembly. Drive the vibration hammer assembly laterally to the working surface of the unpeeled cathode copper plate through the first lead screw transmission mechanism, and hammer the unpeeled cathode copper plate. The hammering time is controlled at 5-10 seconds. After the hammering is completed, the vibration hammer assembly is reset. S4: Start the stripping device, drive the two sets of stripping blades to move synchronously in both directions through the second screw transmission mechanism to cut into the unstripped cathode copper plate, and drive the stripping blades along the vertical direction of the cathode copper plate by the third screw transmission mechanism to strip and cut in stages, and complete the stripping of the first preset size A1, the second preset size A2 and the third preset size A3 in sequence, and finally achieve the complete stripping of the cathode copper plate. S5: Restart the transfer clamping mechanism to transfer the stripped cathode copper plate to the second cathode copper plate conveyor, which will then output the plate.

[0029] Specifically, the traditional peeling method utilizes external mechanical force to overcome the original, intact bonding force between the cathode metal and the starting plate. This implementation step, S3: Activate the vibratory hammer assembly, driven laterally by the first lead screw transmission mechanism to the working surface of the unpeeled cathode copper plate, and hammer the unpeeled cathode copper plate. The hammering time is controlled within 5-10 seconds. After hammering, the vibratory hammer assembly resets. This step, precisely positioned by the first lead screw transmission mechanism, controls the hammering time to 5-10 seconds. The purpose is to inject high-frequency vibration energy into the metal bonding interface before macroscopic peeling occurs. This energy generates microscopic shear stress and fatigue effects at the interface of the two different materials. Invisible microcracks are created at the bonding surface, thus preemptively destroying the strongest initial adhesion forces between the metals, such as van der Waals forces or micrometallurgical bonds, without causing macroscopic damage. This significantly reduces the initial peeling force required for the S4 peeling step, avoiding the fragmentation of brittle metals due to excessive instantaneous stress, and ensuring product integrity. It solves the problems of incomplete peeling and metal residue caused by overly tight edge bonding, eliminating the need for secondary processing and associated costs.

[0030] After pre-loosening, proceed to S4: Start the peeling device, drive two sets of peeling blades to move synchronously in both directions through the second screw drive mechanism to cut into the unpeeled cathode copper plate, and drive the peeling blades along the vertical direction of the cathode copper plate by the third screw drive mechanism to peel and cut in stages, sequentially completing the peeling of the first preset size A1, the second preset size A2, and the third preset size A3, and finally achieving complete peeling of the cathode copper plate; Specifically, through the cooperation of the second and third screw drive mechanisms, it is decomposed into three peeling steps. First, the peeling of the first stage A1 distance takes advantage of the pre-loosening and uses relatively small force to create an initial stable separation opening at the edge; the peeling of the second stage A2 distance and the peeling of the third stage A3 distance directly and continuously expand the separation area along the interface line by tearing along the existing separation line in the first stage peeling; by adopting the above method, the force is highly concentrated on the leading edge of the separation. Since the force is always gentle and localized, it avoids generating huge lateral forces or bending moments on the cathode copper plate, fundamentally preventing the bending and warping deformation of the starting plate, so that it can be reused for a long time and at a high frequency.

[0031] Understandably, since the dimensions, peeling speed, and force of A1, A2, and A3 can all be adjusted programmatically, suitable parameters can be selected for different thicknesses and batches of physical characteristics. It should also be noted that the cleaning in step S1 ensures that the hammering energy in step S3 is transferred to the metal interface without attenuation and ensures that the tool in step S4 is not worn by impurities. The cooperative positioning in step S2 provides a reference for the hammering in step S3 and the precise tool entry in step S4.
