DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0026] The present invention provides a technical solution: a processing device for photovoltaic device production, comprising a working tank 1 and a conductive rod 13 placed on the working tank 1, the conductive rod 13 is fixedly connected to a hook 131 for hanging a workpiece, a cathode 12 is fixedly connected in the working tank 1, a base 11 is fixedly connected to the working tank 1, a motor 2 is fixedly connected to the base 11, a drive shaft 21 is fixedly connected to the output end of the motor 2, a hole adapted to the drive shaft 21 is opened on the working tank 1, a gear 211 is fixedly connected to one end of the drive shaft 21 located in the working tank 1, a hollow disk 44 is connected to a fixed axis rotation in the working tank 1, a gear ring 441 is fixedly connected to the hollow disk 44, the gear 211 is meshed with the gear ring 441, a plurality of connecting rods 442 are fixedly connected to the hollow disk 44, and an inclined plate 443 is fixedly connected to the end of the plurality of connecting rods 442 away from the hollow disk 44.

[0027] Reference Figure 1-Figure 3 , the workpiece to be processed is hung on the hook 131, which is made of metal, so that the current on the conductive rod 13 can be transferred to the workpiece through the hook 131. After the workpiece is hung, the conductive rod 13 is placed on the working tank 1. At this time, the conductive rod 13 and the cathode 12 are energized to start the electrochemical treatment of the workpiece. When the electrochemical treatment starts, the motor 2 is started so that the drive shaft 21 on the motor 2 drives the gear 211 to rotate. Since the gear 211 is fixedly connected to the gear on the hollow disk 44, the gear 211 is rotated. The ring 441 is engaged, and the hollow disk 44 is connected to the working tank 1 for fixed-axis rotation, so that when the gear 211 rotates, it can drive the hollow disk 44 to rotate with its own axis as the center of the circle, and then the rotating hollow disk 44 drives the inclined plate 443 to rotate through the connecting rod 442. Since there are multiple inclined plates 443 and they all have a certain inclination, when the inclined plate 443 is driven by the hollow disk 44 to rotate, it can disturb the electrolyte in the working tank 1, so that the concentration of the electrolyte is uniform, which is convenient for processing the workpiece.

[0028] A cleaning mechanism for removing reactants from the cathode 12 is provided in the working tank 1. The cleaning mechanism includes a ground mounting frame 7, to which a slider 73 and a scraper 72 are fixedly connected. The slider 73 and the scraper 72 are both slidably connected in the working tank 1, and the scraper 72 fits the cathode 12. The cleaning mechanism also includes a telescopic rod 74, the two ends of which are respectively fixedly connected to the mounting frame 7 and the working tank 1. A spring 741 is sleeved on the ground of the telescopic rod 74, and the two ends of the spring 741 are respectively against the mounting frame 7 and the working tank 1. A spoiler 71 for disturbing the electrolyte in the working tank 1 is fixedly connected to the mounting frame 7.

[0029] Reference Figure 2-Figure 4When the hollow disk 44 rotates, the nozzle 444 fixedly connected to the hollow disk 44 will revolve around the axis of the hollow disk 44, and the nozzle 444 will contact the mounting frame 7 and squeeze the mounting frame 7 during the revolution. At this time, the mounting frame 7 overcomes the elastic force of the spring 741 and moves downward. Due to the revolution of the nozzle 444, the movement trajectory of the nozzle 444 is arc-shaped, and when the nozzle 444 reaches the lowest point in the vertical height, it will gradually move away from the mounting frame 7. At this time, the mounting frame 7 moves upward under the action of the spring 741, and the slider 73 and the scraper 72 on the mounting frame 7 are slidably connected in the working groove 1, The mounting frame 7 can slide back and forth vertically in the working tank 1, and since the scraper block 72 is in contact with the cathode 12, the scraper block 72 can scrape off the reactants on the cathode 12 when following the mounting frame 7 to move up and down, so that the contact area between the cathode 12 and the electrolyte in the working tank 1 remains unchanged, thereby maintaining the electrochemical treatment effect. When the mounting frame 7 moves up and down, the spoiler 71 fixedly connected to the mounting frame 7 also moves up and down synchronously, and the spoiler 71 moving up and down can further disturb the electrolyte in the working tank 1, thereby enhancing the flow effect of the electrolyte, promoting the uniform concentration of the electrolyte at each position, and ensuring the treatment of the workpiece.

[0030] The cleaning mechanism also includes a circulation pipe 4, one end of the circulation pipe 4 is fixedly connected to the working tank 1, and the hollow disk 44 is rotatably connected to the other end of the circulation pipe 4. A nozzle 444 is fixedly connected to the hollow disk 44, and the axis of the nozzle of the nozzle 444 is located in the same plane as the scraper block 72, and the nozzle of the nozzle 444 is opened in the direction away from the axis of the hollow disk 44, and the nozzle 444 is intermittently abutted against the mounting bracket 7. The cleaning mechanism also includes a piston cylinder 3 fixedly connected to the working tank 1, and the bottom of the piston cylinder 3 is fixedly connected to a connecting pipe 33 and is connected to the circulation pipe 4 through the connecting pipe 33. A piston plate 31 is slidably connected in the piston cylinder 3, and an inverted U-shaped rod 32 is fixedly connected to the piston plate 31. One end of the inverted U-shaped rod 32 away from the piston plate 31 is fixedly connected to the mounting bracket 7. A first one-way valve 41 and a second one-way valve 42 are respectively provided on both sides of the connecting pipe 33 on the circulation pipe 4.

[0031] Reference Figure 2-Figure 4When the mounting bracket 7 reciprocates vertically, the inverted U-shaped rod 32 fixedly connected to the mounting bracket 7 reciprocates vertically synchronously with the mounting bracket 7, and then the piston plate 31 fixedly connected to the inverted U-shaped rod 32 reciprocates vertically. Since the piston plate 31 is slidably connected to the piston cylinder 3, when the piston plate 31 is pulled upward in the piston cylinder 3, the electrolyte in the working tank 1 can be pumped out into the piston cylinder 3 through the connecting pipe 33 and the circulation pipe 4, and when the piston plate 31 slides downward in the piston cylinder 3, the electrolyte in the working tank 1 can be pumped out. The taken electrolyte is discharged into the hollow disk 44 through the connecting pipe 33 and the circulation pipe 4, and then sprayed out from the nozzle 444 on the hollow disk 44. Since the nozzle of the nozzle 444 is facing away from the axis of the hollow disk 44, and the axis of the nozzle on the nozzle 444 is located in the same plane as the scraper 72, and the scraper 72 is in contact with the cathode 12, the nozzle 444 can eventually spray the electrolyte toward the cathode 12 when rotating with the hollow disk 44, so that the reactants scraped off the cathode 12 by the scraper 72 can be washed away.

[0032] The cleaning mechanism also includes a first semicircular cavity 5 and a second semicircular cavity 51. A mounting block 54 is fixedly connected to the working groove 1. The first semicircular cavity 5 is fixedly connected to the mounting block 54. The second semicircular cavity 51 is rotatably connected to the first semicircular cavity 5. A filter plate 52 is fixedly connected to the second semicircular cavity 51. The side wall of the filter plate 52 fits the inner wall of the first semicircular cavity 5. The first semicircular cavity 5 is fixedly connected to the circulation pipe 4, and the circulation pipe 4 is communicated with the inner cavity of the first semicircular cavity 5 and the second semicircular cavity 51.

[0033] Reference Figure 1 、 Figure 2 and Figure 7 The flushed reactants are pumped together with the electrolyte in the working tank 1 by the piston cylinder 3. The reactants flow through the filter plate 52 in the circulation pipe 4 along with the electrolyte, and the reactants that are cleaned up will be intercepted, so that the reactants can be discharged from the working tank 1. Example

[0034] On the basis of embodiment 1, further, the cleaning mechanism is provided with a replenishing mechanism for replenishing the electrolyte into the working tank 1, the replenishing mechanism includes a replenishing tube 45 connected to the external electrolyte, the replenishing tube 45 is fixedly connected to the circulation tube 4, and the connection between the replenishing tube 45 and the circulation tube 4 is located between the first semicircular cavity 5 and the first one-way valve 41, and the connection between the replenishing tube 45 and the circulation tube 4 is provided with an electromagnetic valve 43, and the replenishing mechanism also includes a floating plate 6 floating on the electrolyte in the working tank 1, and two symmetrically arranged limit rods 65 are fixedly connected in the working tank 1, and the floating plate 6 is located between the two limit rods 65. A vertical plate 62 is fixedly connected to the floating plate 6, and a vertical plate 62 is provided on the vertical plate A guide rod 611 is slidably connected to the through hole, one end of the guide rod 611 is fixedly connected to the rectangular block 61, and the other end of the guide rod 611 is fixedly connected to a retaining ring 612 for preventing the guide rod 611 from separating from the vertical plate 62. A tension spring 613 is sleeved on the guide rod 611, and the two ends of the tension spring 613 are respectively fixedly connected to the rectangular block 61 and the vertical plate 62. Two cross bars 614 are symmetrically fixedly connected to the rectangular block 61, and the two cross bars 614 are respectively fitted with two limit rods 65. An L-shaped rod 63 is fixedly connected to the rectangular block 61, and the L-shaped rod 63 is provided with a pressure-sensitive switch 631 for controlling the solenoid valve 43. The pressure-sensitive switch 631 intermittently abuts against the inner wall of the working tank 1.

[0035] Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As the reaction proceeds, the electrolyte in the working tank 1 is continuously consumed. The consumption of the electrolyte in the working tank 1 causes the float 6 floating on the electrolyte in the working tank 1 to gradually move downward. Since the limit rods 65 are arranged on both sides of the float 6, when the electrolyte in the working tank 1 is disturbed, the float 6 will not deviate far from the original position. The gravity of the float 6 is greater than the tension of the tension spring 613, so that when the float 6 moves downward, the cross bar 614 slides along the limit rod 65 with sufficient force to overcome the tension of the tension spring 613, so that the rectangular block 61 moves toward the inner wall of the working tank 1. The continuous decline of the liquid level can make the rectangular block 61 closer and closer to the inner wall of the working tank 1, so that the rectangular block 61 is fixed on the rectangular block 61. The pressure-sensitive switch 631 on the fixedly connected L-shaped rod 63 also approaches the inner wall of the working tank 1 and finally makes contact. At this time, the pressure-sensitive switch 631 receives pressure from the working tank 1 and controls the solenoid valve 43 to cut off the connection between the end of the circulation pipe 4 away from the hollow disk 44 and the working tank 1 and convert it into a connection between the circulation pipe 4 and the replenishing pipe 45. After the solenoid valve 43 switches the connection direction of the circulation pipe 4, it will maintain for a period of time, and the motor 2 is always in working state, and the hollow disk 44 continues to rotate, and the piston plate 31 continues to slide in the piston cylinder 3. In this state, the piston cylinder 3 transmits new electrolyte to the working tank 1 through the replenishing pipe 45, and the electrolyte in the working tank 1 can be replenished and continue to maintain the reaction. Example

[0036] On the basis of Example 2, further, the supplementary mechanism is provided with a discharge mechanism for discharging impurities in the first semicircular cavity 5 and the second semicircular cavity 51, the discharge mechanism includes a push rack 64 fixedly connected to the floating plate 6, an insertion rod 641 fixedly connected to the working groove 1, a push plate 642 fixedly connected to the insertion rod 641, the push rack 64 and the push plate 642 intermittently abut against each other, a shift rod 511 fixedly connected to the second semicircular cavity 51, the push plate 642 and the shift rod 511 intermittently abut against each other, and a first magnet 53 and a second magnet 512 fixedly connected to the first semicircular cavity 5 and the second semicircular cavity 51 are respectively fixedly connected to each other.

[0037] Reference Figure 1 、 Figure 5 、 Figure 6 and Figure 7 As the rectangular block 61 gradually approaches the inner wall of the working groove 1, the push frame 64 fixedly connected to the rectangular block 61 also gradually approaches the push plate 642 and finally pushes the push plate 642 to slide in the direction away from the working groove 1. Since there are two insertion rods 641, the push plate 642 will not swing when being pushed, and the push plate 642 can always contact the shift rod 511. Therefore, when the push plate 642 is pushed by the push frame 64 to move in the direction away from the working groove 1, it can apply a thrust to the shift rod 511, and the push plate 642 can push the shift rod 511 to make the second semicircular cavity 5 1 rotates relative to the first semicircular cavity 5, and then the reactant residues removed in the first semicircular cavity 5 and the second semicircular cavity 51 can fall mostly by gravity, and the rest can be handled manually. When the liquid level in the working tank 1 is replenished, the float plate 6 rises, and the tension spring 613 pulls the rectangular block 61 back to its original position. At this time, the push frame 64 no longer applies thrust to the push plate 642, and the push plate 642 no longer applies thrust to the lever 511. Then, under the magnetic attraction of the first magnet 53 and the second magnet 512, the second semicircular cavity 51 is again engaged with the first semicircular cavity 5.

[0038] Working principle: When using this processing device for photovoltaic device production, the workpiece to be processed is hung on the hook 131. The hook 131 is made of metal, so that the current on the conductive rod 13 can be transferred to the workpiece through the hook 131. After the workpiece is hung, the conductive rod 13 is placed on the working tank 1. At this time, the conductive rod 13 and the cathode 12 are energized to start electrochemical treatment of the workpiece.

[0039] When the electrochemical treatment starts, the motor 2 is started so that the drive shaft 21 on the motor 2 drives the gear 211 to rotate. Since the gear 211 is engaged with the gear ring 441 fixedly connected to the hollow disk 44, and the hollow disk 44 is connected to the working tank 1 for fixed-axis rotation, the rotation of the gear 211 can drive the hollow disk 44 to rotate around its own axis. The rotating hollow disk 44 then drives the inclined plate 443 to rotate via the connecting rod 442. Since there are multiple inclined plates 443 and each has a certain inclination, when the inclined plate 443 is driven by the hollow disk 44 to rotate, the electrolyte in the working tank 1 can be disturbed, so that the concentration of the electrolyte is uniform, which is convenient for processing the workpiece.

[0040] When the hollow disk 44 rotates, the nozzle 444 fixedly connected to the hollow disk 44 will revolve around the axis of the hollow disk 44 as the center of the circle, and then the nozzle 444 can contact the mounting frame 7 during the revolution and squeeze the mounting frame 7. At this time, the mounting frame 7 overcomes the elastic force of the spring 741 and moves downward. Due to the revolution of the nozzle 444, the movement trajectory of the nozzle 444 is arc-shaped, and then when the nozzle 444 runs to the lowest point of the vertical height, it will gradually move away from the mounting frame 7. At this time, the mounting frame 7 moves upward under the action of the spring 741, and the slider 73 and the scraper 72 on the mounting frame 7 are slidably connected in the working groove 1, and then The mounting frame 7 can slide back and forth vertically in the working tank 1, and because the scraper block 72 is in contact with the cathode 12, the scraper block 72 can scrape the reactants on the cathode 12 when following the up and down movement of the mounting frame 7, so that the contact area between the cathode 12 and the electrolyte in the working tank 1 remains unchanged, thereby maintaining the electrochemical treatment effect. When the mounting frame 7 moves up and down, the spoiler 71 fixedly connected to the mounting frame 7 also moves up and down synchronously, and the spoiler 71 that moves up and down can further disturb the electrolyte in the working tank 1, thereby enhancing the flow effect of the electrolyte, promoting the uniformity of the concentration of the electrolyte at each position, and ensuring the treatment of the workpiece;

[0041] When the mounting frame 7 reciprocates vertically, the inverted U-shaped rod 32 fixedly connected to the mounting frame 7 reciprocates vertically synchronously with the mounting frame 7, and then the piston plate 31 fixedly connected to the inverted U-shaped rod 32 reciprocates vertically. Since the piston plate 31 is slidably connected in the piston cylinder 3, when the piston plate 31 is pulled upward in the piston cylinder 3, the electrolyte in the working tank 1 can be extracted into the piston cylinder 3 through the connecting pipe 33 and the circulation pipe 4. When the piston plate 31 slides downward in the piston cylinder 3, the extracted electrolyte can be discharged into the hollow disk 44 through the connecting pipe 33 and the circulation pipe 4, and then sprayed out from the nozzle 444 on the hollow disk 44. Since the nozzle of the nozzle 444 is oriented away from the axis of the hollow disk 44, and the axis of the nozzle of the nozzle 444 is in the same plane as the scraper 72, and the scraper 72 is in contact with the cathode 12, the nozzle 444 can eventually spray the electrolyte toward the cathode 12 as it rotates with the hollow disk 44, so that the reactants scraped off the cathode 12 by the scraper 72 can be flushed away. The flushed reactants are pumped by the piston cylinder 3 together with the electrolyte in the working tank 1. The reactants are removed after the electrolyte flows through the filter plate 52 in the circulation pipe 4, and the reactants are intercepted, so that the reactants can be discharged from the working tank 1.

[0042] The provision of the first one-way valve 41 and the second one-way valve 42 can ensure that the liquid in the circulation pipe 4 flows in a constant direction toward the hollow disk 44 , thereby preventing the cleaned reactants from flowing back into the working tank 1 .

[0043] As the reaction proceeds, the electrolyte in the working tank 1 is continuously consumed. The consumption of the electrolyte in the working tank 1 causes the float 6 floating on the electrolyte in the working tank 1 to gradually move downward. Since the limit rods 65 are arranged on both sides of the float 6, the float 6 will not deviate far from the original position when the electrolyte in the working tank 1 is disturbed. The gravity of the float 6 is greater than the tension of the tension spring 613, so that the float 6 can move downward. The cross bar 614 slides along the limit rod 65 with enough force to overcome the tension of the tension spring 613, so that the rectangular block 61 moves toward the inner wall of the working tank 1, and the continuous decline of the liquid level can make the rectangular block 61 closer and closer to the inner wall of the working tank 1, so that the rectangular block 61 is fixed on the rectangular block 61. The pressure-sensitive switch 631 on the L-shaped rod 63 connected to the working tank 1 also approaches and eventually makes contact with the inner wall of the working tank 1. At this time, the pressure-sensitive switch 631 receives pressure from the working tank 1 and controls the solenoid valve 43 to cut off the connection between the end of the circulation pipe 4 away from the hollow disk 44 and the working tank 1 and switch the circulation pipe 4 to be connected with the replenishing pipe 45. After the solenoid valve 43 switches the connection direction of the circulation pipe 4, it will maintain for a period of time, and the motor 2 will always be in the working state, so that the hollow disk 44 will continue to rotate, and the piston plate 31 will continue to slide in the piston cylinder 3. In this state, the piston cylinder 3 transmits new electrolyte to the working tank 1 through the replenishing pipe 45, so that the electrolyte in the working tank 1 can be replenished and the reaction can continue.

[0044] When the time for the solenoid valve 43 to switch is reached, the solenoid valve 43 will switch back to its original state. At this time, the electrolyte in the working tank 1 is basically replenished, and then when the solenoid valve 43 switches back to its original state, the electrolyte in the working tank 1 can continue to circulate and filter.

[0045] As the rectangular block 61 gradually approaches the inner wall of the working groove 1, the push frame 64 fixedly connected to the rectangular block 61 also gradually approaches the push plate 642 and finally pushes the push plate 642 to slide in the direction away from the working groove 1. Since there are two insertion rods 641, the push plate 642 will not swing when being pushed, and the push plate 642 can always contact the detent rod 511, so that when the push plate 642 is pushed by the push frame 64 to move in the direction away from the working groove 1, it can apply a thrust to the detent rod 511, and the push plate 642 can push the detent rod 511 to make the second semicircular cavity 51 and the first semicircular cavity 5 rotate relative to each other, and then at this time, it is in the first semicircular cavity 5 The reactant residues removed from the second semicircular cavity 51 can mostly fall due to gravity, and the rest can be handled manually. When the liquid level in the working tank 1 is replenished, the float plate 6 rises, and the tension spring 613 pulls the rectangular block 61 back to its original position. At this time, the push frame 64 no longer applies thrust to the push plate 642, and the push plate 642 no longer applies thrust to the lever 511. Then, under the magnetic attraction of the first magnet 53 and the second magnet 512, the second semicircular cavity 51 is again engaged with the first semicircular cavity 5. The contact surfaces of the first semicircular cavity 5 and the second semicircular cavity 51 are both flat, so that when the electrolyte passes through the first semicircular cavity 5 and the second semicircular cavity 51, there will be no leakage.

[0046] When the electrochemical treatment of the workpiece is completed, the power supply to the conductive rod 13 and the cathode 12 and the rotation of the motor 2 are stopped, and the workpiece can be removed from the hook 131 at this time.
