Description

Technical Field

[0001] The present invention relates to the technical field of electrophoresis equipment, in particular to an electrophoresis equipment for producing automobile parts. Background Art

[0002] Electrophoretic coating is a special coating method in which the conductive object to be coated is immersed in a tank filled with water-diluted electrophoretic paint of relatively low concentration as the anode, and a corresponding cathode is set in the tank. After direct current is passed between the two electrodes for a period of time, a uniform, fine, and water-insoluble coating film is deposited on the surface of the coated object.

[0003] Chinese patent application number CN221701671U discloses an electrophoretic coating device for automotive parts, which relates to the field of automotive parts processing technology. The device comprises a main body and a moving mechanism. The main body comprises an electrophoretic tank, a sub-box mounted on one side of the electrophoretic tank, a deflector mounted on the top of the sub-box, air drying boxes mounted on both sides of the top of the deflector, a storage box mounted inside the sub-box, and fans mounted inside the air drying boxes. The moving mechanism comprises a moving frame, a hanging basket, a pair of mounting frames, and a power box. The width of the moving frame is greater than the width of the deflector. A pair of hydraulic rods are inserted into the top of the moving frame. The output ends of the pair of hydraulic rods extend through the top of the moving frame to the outside and are respectively mounted with fixing blocks. One side of the fixing blocks has a threaded groove. Both sides of the top of the hanging basket have slots, which match the fixing blocks. The slots are threadedly connected to fastening bolts, which are threaded into the threaded grooves. This patent can effectively improve the efficiency of electrophoretic coating on the surface of automotive parts and has high practical value.

[0004] In the electrophoretic coating production system for automotive parts, after the workpiece is electrophoretically coated, it needs to be transferred to the subsequent drainage section through a vertical lifting mechanism. This process inevitably produces loss of tank liquid. As continuous production continues, the accumulated tank liquid loss will cause the electrophoretic tank liquid level to gradually decrease. When the liquid level height is lower than the process set threshold, the tank liquid will not be able to completely cover the automotive parts, affecting the quality of the electroplating of automotive parts. Summary of the Invention

[0005] The present invention provides an electrophoretic coating device for automobile parts production, aiming to solve the technical problem in the related art that in the electrophoretic coating production system of automobile parts, after the workpiece is completed by electrophoresis, it needs to be transferred to the subsequent leaching section through a vertical lifting mechanism. This process inevitably produces tank liquid loss. As continuous production continues, the accumulated tank liquid loss will cause the liquid level of the electrophoretic tank to show a gradual downward trend. When the liquid level height is lower than the process set threshold, the tank liquid will not be able to completely cover the automobile parts, affecting the electroplating quality of the automobile parts.

[0006] The present invention provides an electrophoresis device for automobile parts production, comprising: a bracket, an electrophoresis tank, a mobile component arranged on the bracket, and a carrier arranged at the output end of the mobile component. An overflow port and a liquid inlet are provided on the side wall of the electrophoresis tank, a one-way valve is provided in the liquid inlet, and a liquid replenishing module is also provided on the electrophoresis tank. The liquid replenishing module includes a circulation unit and a liquid replenishing unit; the circulation unit includes a sub-box body arranged in the electrophoresis tank, a partition is provided in the sub-box body, so that an upper chamber and a lower chamber are formed therein, the overflow port is located in the upper chamber, the liquid inlet is located in the lower chamber, a connecting groove communicating with the lower chamber is provided in the upper chamber, and a lifting plate is elastically slidably fitted up and down in the upper chamber. The side wall of the electrophoresis tank is elastically sliding with a limit plate, and the electrophoresis tank is vertically elastically slid with a driving frame, the driving frame has a driving part that abuts against the limit plate, and can push the limit plate to slide when the driving frame is lifted or lowered, and a pushing part is also provided on the driving frame, and an extrusion plate is horizontally sealed and slidable in the lower chamber; the liquid replenishing unit includes a sliding plate that elastically slides on the side wall of the electrophoresis tank, and can push the sliding plate to slide when the pushing part descends, and a sealing plate is elastically slidably matched on the sliding plate, and the sealing plate is provided with a socket, and an insert adapted to the socket is provided on the lifting plate, and a liquid storage tank is provided on the auxiliary box body, and the liquid storage tank is provided with a drain port connected to the lower chamber, and the sealing plate is inserted into the drain port to control its opening and closing.

[0007] As the auto parts gradually enter the electrophoresis buffer, the buffer gradually overflows from the overflow port and enters the upper chamber, causing the lifting plate to rapidly descend until the lower surface of the lifting plate's horizontal portion abuts the upper surface of the limit plate. When the support frame approaches its lower limit, the mounting portion of the support frame presses downward on the horizontal rod of the drive frame, causing the drive frame to descend. The lower inclined section abuts the first side rod and pushes it to the left, causing the limit plate to move leftward. The limit plate fully retracts into the right panel of the electrophoresis tank, releasing the restraint on the lifting plate. The lifting plate rapidly descends and passes over the limit plate. When the first side rod enters the upper inclined section, the force of the second spring is released, driving the first side rod back to the right. The limit plate extends to the right again, blocking the lifting plate. The electrophoresis buffer above the horizontal portion enters the lower chamber. The cylinder drives the extrusion plate to the left, squeezing the electrophoresis buffer in the lower chamber through the liquid inlet and into the electrophoresis tank. When the drive frame descends, the pushing part will push the second side rod to the left. When the plug is inserted into the socket, it means that there is enough electrophoresis buffer in the electrophoresis tank, and the sliding plate cannot pull the blocking plate to move. When the electrophoresis buffer in the electrophoresis tank decreases, the plug cannot be inserted into the socket. The sliding plate pulls the blocking plate to the left, opening the drain port. The electrophoresis buffer in the liquid reservoir enters the lower chamber to replenish the electrophoresis buffer. The automobile parts enter the electrophoresis buffer, causing the electrophoresis buffer to overflow from the overflow port. The amount of overflowed electrophoresis buffer is used to determine whether the electrophoresis buffer in the electrophoresis tank has decreased. At the same time, when the electrophoresis buffer in the electrophoresis tank decreases, new electrophoresis buffer can be automatically added through the liquid reservoir to always keep a sufficient amount of electrophoresis buffer in the electrophoresis tank to ensure the electrophoresis quality of the automobile parts.

[0008] Preferably, a screen is provided in the upper chamber, and the screen is located below the overflow port.

[0009] When the auto parts enter the electrophoresis buffer, the upper liquid will overflow from the overflow port, and the dust and impurities on the upper layer will also be brought out. Finally, after being filtered through the screen, the dust and impurities on the surface of the electrophoresis buffer are cleaned.

[0010] Preferably, a first spring is provided between the lifting plate and the partition plate, the lifting plate is in an L-shaped structure, and has a horizontal portion and a vertical portion.

[0011] Preferably, the driving frame is an inverted U-shaped structure, and the driving frame has a horizontal rod and two vertical rods. The horizontal rod is fixed to the upper ends of the two vertical rods. A vertically arranged mounting groove is opened on the electrophoresis tank, and the vertical rod is slidably assembled in the mounting groove. The upper end of the vertical rod is located above the electrophoresis tank.

[0012] The lowering of the carrier frame is used to control the lifting of the driving frame, and the lifting of the driving frame can control the movement of the limit plate and the sliding plate.

[0013] Preferably, the driving portion includes a lower vertical section, a lower inclined section, an upper inclined section and an upper vertical section. The lower vertical section, the lower inclined section, the upper inclined section and the upper vertical section are arranged in sequence from bottom to top and are connected to each other. The lower inclined section gradually tilts downward from left to right, and the upper inclined section gradually tilts upward from left to right. The lower inclined section and the upper inclined section are arranged in an eight-shaped shape.

[0014] Preferably, the pushing portion is arranged obliquely, and the pushing portion gradually tilts downward from left to right.

[0015] By arranging the lower vertical section, the lower inclined section, the upper inclined section and the upper vertical section, the limit plate can be driven to slide when the driving frame is raised or lowered.

[0016] Preferably, first side rods are fixedly mounted on the front and rear side walls of the limiting plate, the two first side rods are both cylindrical structures, and the two first side rods are coaxially arranged.

[0017] Preferably, a stirring blade is rotatably mounted on the bottom of the electrophoresis tank, and the liquid inlet faces the blade of the stirring blade.

[0018] When the electrophoresis buffer in the lower chamber enters the electrophoresis tank from the liquid inlet, it can drive the stirring blade to rotate. The stirring blade can disturb the electrophoresis buffer in the electrophoresis tank, so that the components in the electrophoresis buffer can be distributed more evenly.

[0019] Preferably, the fluid replenishment modules are provided in two groups, and the two groups of fluid replenishment modules are respectively arranged on the left and right sides of the electrophoresis tank, and the left and right groups of fluid replenishment modules are symmetrically arranged with each other.

[0020] Preferably, the moving assembly includes a lifting frame that slides up and down to cooperate with the bracket, a track is provided at the bottom of the lifting frame, the length of the track extends in the left and right directions, a sliding block is installed on the track for sliding in the left and right directions, a connecting rod is fixedly installed on the lower surface of the sliding block, and the supporting frame is fixed to the lower end of the connecting rod.

[0021] The above technical solution provides the following beneficial effects: as the automotive parts gradually enter the electrophoresis buffer, the electrophoresis buffer gradually overflows from the overflow port, and the overflowed electrophoresis buffer enters the upper chamber, causing the lifting plate to rapidly descend until the lower surface of the horizontal portion of the lifting plate abuts the upper surface of the limit plate. When the support frame descends close to the limit position, the mounting portion of the support frame presses the horizontal rod portion of the drive frame downward, causing the drive frame to descend. The lower inclined section abuts the first side rod and pushes the first side rod to move to the left, causing the limit plate to move to the left. The limit plate fully retracts into the right panel of the electrophoresis tank, releasing the restriction on the lifting plate. The lifting plate rapidly descends and passes over the limit plate. When the first side rod enters the upper inclined section, the elastic force of the second spring is released, driving the first side rod to reset to the right, and the limit plate extends to the right again, blocking the lifting plate. The electrophoresis buffer above the horizontal portion enters the lower chamber. The cylinder drives the extrusion plate to move to the left, squeezing the electrophoresis buffer in the lower chamber through the liquid inlet into the electrophoresis tank. When the drive frame descends, the pushing part will push the second side rod to the left. When the plug is inserted into the socket, it means that there is enough electrophoresis buffer in the electrophoresis tank, and the sliding plate cannot pull the blocking plate to move. When the electrophoresis buffer in the electrophoresis tank decreases, the plug cannot be inserted into the socket. The sliding plate pulls the blocking plate to the left, opening the drain port. The electrophoresis buffer in the liquid reservoir enters the lower chamber to replenish the electrophoresis buffer. The automobile parts enter the electrophoresis buffer, causing the electrophoresis buffer to overflow from the overflow port. The amount of overflowed electrophoresis buffer is used to determine whether the electrophoresis buffer in the electrophoresis tank has decreased. At the same time, when the electrophoresis buffer in the electrophoresis tank decreases, new electrophoresis buffer can be automatically added through the liquid reservoir to always keep a sufficient amount of electrophoresis buffer in the electrophoresis tank to ensure the electrophoresis quality of the automobile parts.

[0022] When the auto parts enter the electrophoresis buffer, the upper liquid will overflow from the overflow port, and the dust and impurities on the upper layer will also be brought out. Finally, after being filtered through the screen, the dust and impurities on the surface of the electrophoresis buffer are cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 8 As shown, a specific embodiment of the electrophoresis equipment for automobile parts production of the present invention includes an electrophoresis module and a fluid replenishment module.

[0035] like Figure 1 and Figure 2 As shown, the electrophoresis module includes a carrying unit and an electrophoresis unit. The carrying unit includes a bracket 10 , a lifting frame 11 , a track 12 , a sliding block 13 , a connecting rod 14 and a carrying frame 15 .

[0036] The bracket 10 is fixed vertically on the ground. In this embodiment, the brackets 10 are arranged in two rows, with two brackets spaced apart in each row. A lifting frame 11 slides up and down on the bracket 10. The bracket 10 is provided with a vertically arranged slideway, and a slider is provided on the bracket 10 to cooperate with the slideway. The slider and the slideway cooperate to enable the lifting frame 11 to be raised and lowered along the bracket 10. The bracket 10 is provided with a drive mechanism to drive the lifting frame 11 up and down. The drive mechanism can be a telescopic cylinder or a screw structure, etc.

[0037] A track 12 is provided at the bottom of the lifting frame 11. The track 12 extends in the left-right direction. A sliding block 13 is slidably mounted on the track 12 in the left-right direction. The sliding block 13 is provided with a driving source to drive the sliding block 13 along the track 12. In this embodiment, the driving source can be a motor and a roller. That is, a motor is fixedly mounted on the sliding block 13, and a roller is mounted on the output end of the motor. The roller is in transmission cooperation with the track 12, so that when the motor drives the roller to rotate, the sliding block 13 can move along the track 12.

[0038] A connecting rod 14 is fixedly installed on the lower surface of the sliding block 13. In this embodiment, the connecting rod 14 is a rod-shaped structure made of metal. A supporting frame 15 is fixedly installed on the lower end of the connecting rod 14. The supporting frame 15 has a horizontally arranged mounting portion and multiple vertically arranged hanging portions. The mounting portion is fixedly connected to the lower end of the connecting rod 14. Multiple hanging portions are fixedly installed on the bottom of the mounting portion. The hanging portion is used to install and fix automobile parts, so that multiple hanging portions can install multiple automobile parts at the same time.

[0039] The electrophoresis unit includes an electrophoresis tank 16, a rectangular structure with an upper opening. The tank 16 comprises a base plate and four circumferential panels. Electrophoresis buffer is contained within the tank 16, and when an automotive part enters the electrophoresis buffer, it undergoes electrophoresis treatment. Two side walls of the tank 16, near the upper end, each feature a rectangular overflow port 17 extending longitudinally.

[0040] The liquid level of the electrophoresis buffer in the electrophoresis tank 16 is slightly lower than the overflow port 17 , so when the carrier 15 drives the automobile parts into the electrophoresis buffer, the liquid level will flow out from the overflow port 17 to the rehydration module, which will be described in detail below.

[0041] like Figure 2 As shown, in this embodiment, two groups of rehydration modules are provided, and the two groups of rehydration modules are respectively arranged on the left and right sides of the electrophoresis tank 16, and the left and right groups of rehydration modules are arranged symmetrically with each other. Each group of rehydration modules includes a circulation unit and a rehydration unit. The following description will be expanded on the rehydration module located on the right side as an example.

[0042] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 as well as Figure 8 As shown, the circulation unit includes a sub-box 20, a screen 21, a partition 22, a lifting plate 30, a first spring 31, a horizontal part 32, a vertical part 33, an insert block 35, a limit plate 40, a second spring 41, a first side rod 42, a drive frame 50, a third spring 51, a drive part 52, a cylinder 60 and an extrusion plate 61.

[0043] The sub-box 20 is fixedly mounted on the side of the electrophoretic tank 16 and is welded to the tank 16. The sub-box 20 defines a chamber with an upper opening on its interior. A horizontally arranged partition 22 is fixedly mounted on the interior of the sub-box 20, dividing the chamber within the sub-box 20 into an upper chamber 23 and a lower chamber 24. A through-hole 25 extending vertically through the side of the partition 22 facing away from the electrophoretic tank 16 is provided. Specifically, the left end of the partition 22 is fixedly connected to the right sidewall of the electrophoretic tank 16, and a gap is formed between the right end of the partition 22 and the sub-box 20, forming the through-hole 25.

[0044] A screen 21 is fixedly installed in the upper chamber 23. The screen 21 is arranged horizontally. It should be noted that the screen 21 is lower than the height of the overflow port 17, so that the electrophoresis buffer overflowing from the overflow port 17 can pass through the screen 21 and fall. The screen 21 can filter the electrophoresis buffer overflowing from the overflow port 17. When the automotive parts enter the electrophoresis tank 16, dust and impurities on the automotive parts may float on the upper surface of the electrophoresis buffer. At the same time, dust floating in the air in the workshop will also fall on the surface of the electrophoresis buffer. When the electrophoresed automotive parts leave the electrophoresis buffer, the dust and impurities floating on the liquid surface will adhere to the automotive parts, thereby affecting the electrophoresis quality of the automotive parts. When the automotive parts enter the electrophoresis buffer, the upper layer of liquid will overflow from the overflow port 17, and the dust and impurities on the upper layer will also be taken out. Finally, after being filtered by the screen 21, the dust and impurities on the upper surface of the electrophoresis buffer are cleaned.

[0045] A communication groove 26 is provided on the right side wall of the upper chamber 23 near the bottom. The bottom of the communication groove 26 corresponds to and is connected to the through-hole 25 , that is, the communication groove 26 is connected to the lower chamber 24 through the through-hole 25 .

[0046] A lifting plate 30 is sealed and slidably mounted within the upper chamber 23. The lifting plate 30 can slide up and down within the upper chamber 23. A first spring 31 is disposed between the lifting plate 30 and the partition 22. One end of the first spring 31 is fixedly connected to the partition 22, and the other end of the first spring 31 is fixedly connected to the lifting plate 30. The first spring 31 can provide elastic force to reset the lifting plate 30.

[0047] like Figure 3 and Figure 5 As shown, the lifting plate 30 is located below the screen 21. The lifting plate 30 has an L-shaped structure and includes a horizontal portion 32 and a vertical portion 33. The horizontal portion 32 is in sealed sliding engagement with the inner wall of the upper chamber 23. The vertical portion 33 of the lifting plate 30 is in sliding engagement with the right side wall of the upper chamber 23, and the lower end of the vertical portion 33 passes through the through hole 25 and penetrates into the lower chamber 24 below.

[0048] An escape groove 34 is formed on the vertical portion 33 of the lifting plate 30 . The escape groove 34 is a square structure, and a plurality of inserting blocks 35 are spaced apart along the front-to-back direction on the top wall of the escape groove 34 .

[0049] like Figure 3 、 Figure 4 、 Figure 5 as well as Figure 7 As shown, a mounting groove is provided on the outer side wall of the right side panel of the electrophoresis tank 16. A limit plate 40 is mounted in the mounting groove for horizontal sliding in the left-right direction. The right end of the limit plate 40 extends into the upper chamber 23. The left end of the limit plate 40 is connected to the electrophoresis tank 16 via a second spring 41. That is, one end of the second spring 41 is connected to the electrophoresis tank 16, and the other end of the second spring 41 is fixedly connected to the limit plate 40. The second spring 41 can provide elastic force to reset the limit plate 40.

[0050] First side rods 42 are fixedly mounted on the front and rear side walls of the limiting plate 40 near the left end. The front and rear first side rods 42 are both cylindrical structures, and the two first side rods 42 are coaxially arranged with their axes extending in the front-to-back direction.

[0051] like Figure 4 、 Figure 6 and Figure 7 As shown, a drive frame 50 is vertically slidably installed on the right side panel of the electrophoresis tank 16. The drive frame 50 is an inverted U-shaped structure. A third spring 51 is arranged between the drive frame 50 and the electrophoresis tank 16. One end of the third spring 51 is fixedly connected to the electrophoresis tank 16, and the other end of the third spring 51 is fixedly connected to the drive frame 50. The third spring 51 can provide elastic force for resetting the drive frame 50.

[0052] The drive frame 50 comprises a horizontal rod and two vertical rods, spaced apart in the front-to-back direction. The horizontal rod is fixed to the upper ends of the two vertical rods. The right side panel of the electrophoresis tank 16 is provided with vertically spaced mounting slots, each of which slides vertically into its corresponding mounting slot. The upper ends of the vertical rods are positioned above the right side panel of the electrophoresis tank 16. In other words, in the initial state, the horizontal rod is positioned above the electrophoresis tank 16.

[0053] like Figure 7 As shown, each vertical rod of the drive frame 50 is provided with a driving portion 52, which abuts against the first side rod 42 to push the first side rod 42 to move. The driving portion 52 includes a lower vertical section 53, a lower inclined section 54, an upper inclined section 55, and an upper vertical section 56. The lower vertical section 53, the lower inclined section 54, the upper inclined section 55, and the upper vertical section 56 are arranged in sequence from bottom to top and are interconnected.

[0054] The lower inclined section 54 gradually slopes downward from left to right, and the upper inclined section 55 gradually slopes upward from left to right, and the lower inclined section 54 and the upper inclined section 55 are arranged in an V-shape. The lower vertical section 53 and the upper vertical section 56 are both arranged vertically, with the lower end of the lower inclined section 54 connected to the upper end of the lower vertical section 53, the lower end of the upper inclined section 55 connected to the upper end of the lower inclined section 54, and the lower end of the upper vertical section 56 connected to the upper end of the upper inclined section 55.

[0055] A pushing portion 57 is further provided near the lower end of the vertical rod portion of the driving frame 50 . The pushing portion 57 is tilted and gradually tilts downward from left to right.

[0056] In the initial state, the first side rod 42 is located at the lower vertical section 53. When the driving frame 50 descends, the lower inclined section 54 gradually abuts against the first side rod 42 and pushes the first side rod 42 to move to the left. The second spring 41 will be compressed. When the first side rod 42 enters the upper inclined section 55, the elastic force of the second spring 41 is released, driving the first side rod 42 to reset to the right. Finally, when the driving frame 50 descends to the limit position, the first side rod 42 reaches the upper vertical section 56.

[0057] When the sliding block 13 drives the automobile parts on the carrier 15 to move to the top of the electrophoresis tank 16, electrophoresis of the automobile parts begins. The lifting frame 11 drives the carrier 15 to descend and enter the electrophoresis buffer in the electrophoresis tank 16, so that the automobile parts enter the electrophoresis buffer. As the automobile parts gradually enter the electrophoresis buffer, the liquid level of the electrophoresis buffer rises, and the electrophoresis buffer gradually overflows from the overflow port 17. The overflowed electrophoresis buffer enters the upper chamber 23. The overflowed electrophoresis buffer is filtered by the screen 21 and falls above the lifting plate 30 below. As the overflowed electrophoresis buffer increases, the lifting plate 30 is rapidly lowered under the action of gravity, and the first spring 31 is compressed until the lower surface of the horizontal portion 32 of the lifting plate 30 abuts the upper surface of the limit plate 40, that is, the limit plate 40 limits the descent of the lifting plate 30. At this time, the vertical portion 33 of the lifting plate 30 completely blocks the connecting groove 26, and the horizontal portion 32 is located above the connecting groove 26.

[0058] When the lifting frame 11 drives the carrier 15 to continue to descend, and the carrier 15 descends and approaches the limit position, the mounting portion of the carrier 15 will press the horizontal rod portion of the driving frame 50 downward, causing the driving frame 50 to descend, and the first side rod 42 reaches the lower inclined section 54 from the lower vertical section 53. The lower inclined section 54 abuts against the first side rod 42 and pushes the first side rod 42 to move to the left, and the second spring 41 will be compressed, causing the limit plate 40 to move to the left, and the limit plate 40 is completely retracted into the right side panel of the electrophoresis tank 16, releasing the restriction on the lifting plate 30, and the lifting plate 30 quickly descends and passes over the limit plate 40. When the first side rod 42 enters the upper inclined section 55, the elastic force of the second spring 41 is released, driving the first side rod 42 to reset to the right side. Finally, when the driving frame 50 descends to the limit position, the first side rod 42 reaches the position of the upper vertical section 56. At this time, the limit plate 40 extends to the right again, blocking the top of the lifting plate 30.

[0059] At this time, the horizontal portion 32 of the lifting plate 30 reaches the position of the connecting groove 26, and the upper surface of the horizontal portion 32 is lower than the upper groove wall of the connecting groove 26. The electrophoresis buffer above the horizontal portion 32 will enter the connecting groove 26, and then enter the lower chamber 24 through the perforation 25.

[0060] After the electrophoresis of the automobile parts is completed, the lifting frame 11 drives the carrier frame 15 to rise, so that the automobile parts are removed from the electrophoresis tank 16, and then the driving frame 50 and the lifting plate 30 are both raised and reset.

[0061] like Figure 2As shown, a cylinder 60 is installed near the bottom on the right side of the auxiliary box 20, and the telescopic part of the cylinder 60 penetrates into the lower chamber 24. The lower chamber 24 is sealed and slidably installed with an extrusion plate 61 in the left and right directions, and the extrusion plate 61 is fixedly connected to the telescopic part of the cylinder 60. A liquid inlet 18 that passes through the left and right sides is opened near the bottom of the right side panel of the electrophoresis tank 16. A one-way valve (not shown in the figure) is installed in the liquid inlet 18. The lower chamber 24 is connected to the electrophoresis tank 16 through the liquid inlet 18. The cylinder 60 drives the extrusion plate 61 to move to the left, squeezing the electrophoresis buffer in the lower chamber 24 into the electrophoresis tank 16 through the liquid inlet 18.

[0062] like Figure 3 、 Figure 4 and Figure 7 As shown, the liquid replenishing unit includes a sliding plate 70 , a fourth spring 71 , a second side rod 72 , a blocking plate 73 and a liquid storage tank 75 .

[0063] A sliding plate 70 is installed on the right side panel of the electrophoretic tank 16 for horizontal sliding in the left and right directions. The sliding plate 70 and the electrophoretic tank 16 are connected by a fourth spring 71, that is, one end of the fourth spring 71 is fixedly connected to the sliding plate 70, and the other end is fixedly connected to the electrophoretic tank 16. The fourth spring 71 can provide elastic force for the sliding plate 70 to be reset.

[0064] Second side rods 72 are fixedly mounted on both the front and rear sides of the sliding plate 70. The two front and rear second side rods 72 are coaxially arranged, with their axes extending in the front-to-back direction. The second side rods 72 are located in the lifting path of the push portion 57 on the drive frame 50. When the push portion 57 descends, it can abut against the second side rods 72.

[0065] A blocking plate 73 is mounted horizontally and slidably on the right side of the sliding plate 70, and is connected to the sliding plate 70 via a spring. The blocking plate 73 is located at the bottom of the partition 22 and slides in engagement with it. The blocking plate 73 is provided with a plurality of sockets 74, which correspond to the insert blocks 35 above and below.

[0066] A liquid reservoir 75 is located on the right side of the auxiliary housing 20, storing fresh electrophoresis buffer. A drain port 76 is provided on the sidewall of the auxiliary housing 20, connecting the liquid reservoir 75 with the lower chamber 24. The right end of the sealing plate 73 has a raised portion that inserts into the drain port 76, sealing it.

[0067] When enough electrophoresis buffer overflows from the electrophoresis tank 16, the lifting plate 30 can descend to the bottom limit position. When the overflowing electrophoresis buffer gradually decreases, the lifting plate 30 cannot descend to the limit position and cannot cross the limit plate 40. When the lifting plate 30 can descend to the bottom limit position, the insert 35 will be inserted into the insertion hole 74, limiting the sliding of the blocking plate 73.

[0068] Each time the drive frame 50 descends, the push portion 57 pushes the second side rod 72 to the left. When the insert 35 is inserted into the receptacle 74, it indicates that there is sufficient electrophoresis buffer in the electrophoresis tank 16. The sliding plate 70 cannot pull the blocking plate 73 to move, and the spring connecting the two will be stretched. When the electrophoresis buffer in the electrophoresis tank 16 is low, the insert 35 cannot be inserted into the receptacle 74. The sliding plate 70 pulls the blocking plate 73 to the left, opening the drain port 76. The electrophoresis buffer in the reservoir 75 enters the lower chamber 24, replenishing the electrophoresis buffer and maintaining a sufficient amount of electrophoresis buffer in the electrophoresis tank 16.

[0069] A stirring blade 19 is also rotatably mounted at the bottom of the electrophoresis tank 16. The liquid inlets 18 in the rehydration modules on the left and right sides are staggered front to back, with the liquid inlets 18 facing the blades of the stirring blade 19. That is, the liquid inlet 18 on the right panel of the electrophoresis tank 16 is located near the bottom and the rear side, while the liquid inlet 18 on the left panel of the electrophoresis tank 16 is located near the bottom and the front side. As a result, when the electrophoresis buffer in the lower chambers 24 on the left and right sides enters the electrophoresis tank 16 through the liquid inlets 18, it can drive the stirring blade 19 to rotate, disturbing the electrophoresis buffer in the electrophoresis tank 16, so that the components in the electrophoresis buffer are more evenly distributed.

[0070] The working principle of the present invention is as follows: when the sliding block 13 drives the automobile parts on the carrier 15 to move to the top of the electrophoresis tank 16, electrophoresis of the automobile parts begins, and the lifting frame 11 drives the carrier 15 to descend and enter the electrophoresis buffer in the electrophoresis tank 16, so that the automobile parts enter the electrophoresis buffer. As the automobile parts gradually enter the electrophoresis buffer, the liquid level of the electrophoresis buffer rises, and the electrophoresis buffer gradually overflows from the overflow port 17. The overflowed electrophoresis buffer enters the upper chamber 23, and the overflowed electrophoresis buffer is filtered by the screen 21 and falls above the lifting plate 30 below. As the overflowed electrophoresis buffer increases, the lifting plate 30 is rapidly lowered under the action of gravity, and the first spring 31 is compressed until the lower surface of the horizontal portion 32 of the lifting plate 30 abuts against the upper surface of the limit plate 40, that is, the limit plate 40 limits the descent of the lifting plate 30. At this time, the vertical portion 33 of the lifting plate 30 completely blocks the connecting groove 26, and the horizontal portion 32 is located above the connecting groove 26. When the lifting frame 11 drives the carrier 15 to continue to descend, and the carrier 15 descends and approaches the limit position, the mounting portion of the carrier 15 will press the horizontal rod portion of the driving frame 50 downward, causing the driving frame 50 to descend, and the first side rod 42 reaches the lower inclined section 54 from the lower vertical section 53. The lower inclined section 54 abuts against the first side rod 42 and pushes the first side rod 42 to move to the left, and the second spring 41 will be compressed, causing the limit plate 40 to move to the left, and the limit plate 40 is completely retracted into the right side panel of the electrophoresis tank 16, releasing the restriction on the lifting plate 30, and the lifting plate 30 quickly descends and passes over the limit plate 40. When the first side rod 42 enters the upper inclined section 55, the elastic force of the second spring 41 is released, driving the first side rod 42 to reset to the right side. Finally, when the driving frame 50 descends to the limit position, the first side rod 42 reaches the position of the upper vertical section 56. At this time, the limit plate 40 extends to the right again, blocking the top of the lifting plate 30. At this point, the horizontal portion 32 of the lifting plate 30 reaches the position of the connecting groove 26, and the upper surface of the horizontal portion 32 is lower than the upper groove wall of the connecting groove 26. The electrophoresis buffer above the horizontal portion 32 will enter the connecting groove 26 and then enter the lower chamber 24 through the perforation 25. After completing the electrophoresis of the automobile parts, the lifting frame 11 drives the supporting frame 15 to rise, allowing the automobile parts to leave the electrophoresis tank 16. Then, the driving frame 50 and the lifting plate 30 are both raised and reset. The cylinder 60 drives the extrusion plate 61 to move to the left, squeezing the electrophoresis buffer in the lower chamber 24 into the electrophoresis tank 16 through the liquid inlet 18.

[0071] Each time the drive frame 50 descends, the push portion 57 pushes the second side rod 72 to the left. When the insert 35 is inserted into the receptacle 74, it indicates that there is sufficient electrophoresis buffer in the electrophoresis tank 16. The sliding plate 70 is unable to pull the blocking plate 73 to move, and the spring connecting the two is stretched. When the electrophoresis buffer in the electrophoresis tank 16 is low, the insert 35 cannot be inserted into the receptacle 74. The sliding plate 70 pulls the blocking plate 73 to the left, opening the drain port 76. The electrophoresis buffer in the reservoir 75 enters the lower chamber 24, replenishing the electrophoresis buffer and maintaining a sufficient amount of electrophoresis buffer in the electrophoresis tank 16.

A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
