Description

TECHNICAL FIELD

[0003] The existing electrophoretic lifting appliance has a simple structure and can meet the single hoisting requirement. However, the following problems are generally present.

[0004] 1. The electrophoretic lifting appliance mainly comprises a moving frame and a hooking frame. The moving frame is a moving part on the electrophoretic coating tank and has a hanging ring fixedly welded thereon for hooking the hooking frame.

DETAILED DESCRIPTION

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0040] As shown in the drawings, Figures 1-4 An automobile part electrophoresis lifting appliance is provided in an embodiment of the present application, which comprises:

[0041] The rectangular lifting frame 1 is provided with a moving frame 101 at the top. It is to be noted that the device is installed on the upper side of an existing electrophoresis process coating tank, is hoisted and moved by a gantry crane, and the moving frame 101 is used as a connecting component so that the device as a whole can be moved on the electrophoresis tank.

[0042] The loading and unloading structure 2 comprises two clamping cross rails 201 fixedly connected to the inner top of the rectangular lifting frame 1. The two clamping cross rails 201 are arranged in parallel and are each provided with a strip-shaped through groove 202 at the opposite side. The strip-shaped through grooves 202 are provided with a plurality of limiting grooves 203 arranged along the length direction. The plurality of limiting grooves 203 can be adjusted in position and number as required, increasing flexibility. The jacking plate 204 is vertically and slidingly installed in the inner bottom of the clamping cross rail 201.

[0043] The plurality of hanging racks 3 are hung and installed between the two clamping rails 201, and the hanging rack 3 comprises a hanging rod 301 hung and installed between two limiting grooves 203, the bottom of the rotating disc 302 connected with the hanging rod 301, the rotating end of the rotating disc 302 fixedly connected with a horizontal frame 303, the horizontal frame 303 fixedly connected with two L-shaped vertical plates 304 at both ends, the two L-shaped vertical plates 304 arranged in parallel and each provided with a plurality of hooking grooves 305 along the length direction, and a plurality of bearing frames 4 are hung and installed between the two L-shaped vertical plates 304 through the hooking grooves 305. It should be noted that the hanging rack 3 is hung and connected in the strip-shaped through groove 202 in the clamping rail 201 through the hanging rod 301, and is positioned through the limiting groove 203. When the hanging rack 3 is installed, it is generally placed on the movable frame first, the movable frame is pushed to the side of the rectangular hanging frame 1, and then the hanging rack 3 is manually lifted and hung on the rectangular hanging frame 1. This requires a lot of manpower, and there is a risk of accidental loss of personnel, which may cause the workpieces to scatter. The loading and unloading structure 2 of the device can be used not only on the rectangular hanging frame 1 but also on the movable frame. When the hanging rack 3 is installed, the movable frame is only needed to be pushed to the side of the rectangular hanging frame 1 and connected with the loading and unloading port of the clamping rail 201, and then the limiting groove 203 is covered by moving the lifting plate 204, so that a flat surface is formed at the bottom of the strip-shaped through groove 202. The hanging rod 301 can be horizontally pushed into the groove. Then the lifting plate 204 is lowered, the hanging rod 301 is automatically dropped into the limiting groove 203 to complete the installation operation. When disassembling, the hanging rod 301 can be pushed out by moving the lifting plate 204 upward, and then the hanging rod 301 is pushed horizontally onto the movable frame, thereby saving a lot of manpower and ensuring the safety of loading and unloading.

[0044] The lifting and vibrating mechanism 5 is arranged between the rotating disc 302 and the hanging rod 301 and used to drive the rotating disc 302 to move up and down.

[0045] It should be noted that after the automobile parts are immersed in the electrophoresis tank, a certain period of time is needed for standing to make the bubbles separate, and then the power is turned on. For complex parts, the lifting and vibrating mechanism 5 in the device can be used to drive the whole part to move up and down in the electrophoresis tank, so that the bubbles remaining in the part are quickly discharged, the possibility of bubble retention is reduced, and the quality of subsequent electrophoretic coating is ensured. During electrophoresis, bubbles may be retained on the surface of the workpiece. The rotating disc 302 can be used to drive the horizontal frame 303 and the part to rotate in the electrophoresis tank at regular intervals, so that the bubbles are separated and the quality of electrophoretic coating is ensured. After electrophoresis is completed, the part is lifted out of the electrophoresis tank, and the liquid remaining in the cavity needs a certain period of time to drain. At this time, the lifting and vibrating mechanism 5 can be used to drive the part to vibrate up and down, so that the residual liquid in the cavity flows out quickly, so as to quickly enter the next process and improve the overall efficiency.

[0047] As Figures 2-3 The specific structure of the jacking plate 204 is disclosed, the jacking plate 204 comprises a support plate 2041 vertically slidingly installed in the inner bottom of the U-shaped strip plate 2011, a screw knob 2042 penetrating the U-shaped strip plate 2011 is rotatably arranged on the bottom side of the support plate 2041, sliding columns 2043 slidingly penetrating the U-shaped strip plate 2011 are fixedly connected to both ends of the support plate 2041, when the hanging rod 301 needs to be installed or disassembled, the screw knob 2042 can be rotated to be screwed with the U-shaped strip plate 2011, so as to drive the support plate 2041 to be raised or lowered, thereby facilitating the subsequent moving-in or moving-out operation of the hanging rod 301, the lifting force is converted into a screw rotation force, which can effectively reduce the manpower, facilitate the overall lifting of the hanging rod 301, and facilitate the subsequent translation disassembly operation, thereby increasing the convenience.

[0048] As Figure 4As shown, the connecting structure of the bottom of the cross frame 303 is disclosed, the bottom end of the two L-shaped vertical plates 304 is fixedly connected with a support rod 3041, and a connecting rod 3042 is arranged between the two support rods 3041, and it should be noted that the support rod 3041 and the connecting rod 3042 are both cylindrical, which is convenient for the separation of the solution, and the support rod 3041 can increase the contact area with the bottom surface when the hanging frame 3 is placed on the ground, thereby improving the supporting stability, and the connecting rod 3042 is installed between the support rods 3041, which can form a rectangular frame with the cross frame 303 and the two L-shaped vertical plates 304, thereby increasing the stability of the structure and prolonging the service life.

[0049] As shown in the figure, Figure 5 As shown, the specific structure of the bearing frame 4 is disclosed, the bearing frame 4 comprises a column 401 arranged horizontally, the two ends of the column 401 are provided with positioning vertical plates 402 inserted into the hooking grooves 305, a plurality of extension rods 403 perpendicular to the column 401 are arranged on the column 401 along the length direction of the column 401, the two ends of the extension rod 403 are provided with triangular hooks 404, and the two triangular hooks 404 are arranged upward and oppositely. The triangular hook 404 is a triangular plate structure, which can be inserted into the hole of the part and contact with the hole by the edge, so as to reduce the contact area and facilitate electrophoretic coating. The bearing frame 4 is detachably connected through the positioning vertical plates 402 and the hooking grooves 305, so as to be separately detached to form a modular structure, facilitate batch installation and disassembly operation of the parts, and increase the flexibility of the device.

[0050] As shown in the figure, Figures 6-8As shown in the figure, the specific structure of the rotating disc 302 of the application is disclosed, the rotating disc 302 comprises a circular frame 3021, a rotating column 3022 penetrating through the bottom of the circular frame 3021 is rotatably installed in the circular frame 3021 through a bearing, the bottom of the rotating column 3022 is structured with a connecting disc 3023 connected with the horizontal frame 303, one end of the rotating column 3022 located in the circular frame 3021 is fixedly connected with a pushing rod 3024, the circular frame 3021 is structured with a spacing rod 3025 arranged opposite to the pushing rod 3024, the top of the circular frame 3021 is structured with an air inlet pipe 3026 and an air outlet pipe 3027 communicated with the inside of the circular frame 3021, the air inlet pipe 3026 and the air outlet pipe 3027 are arranged on the two sides of the spacing rod 3025 respectively, the air inlet pipe 3026 and the air outlet pipe 3027 are both installed with a one-way valve 6, the air direction of the one-way valve 6 in the air inlet pipe 3026 is towards the inside of the circular frame 3021, and the air direction of the air outlet pipe 3027 is towards the outside of the circular frame 3021, it is to be noted that the circular frame 3021 is structured with an annular cavity arranged around the rotating column 3022, the spacing rod 3025 is arranged in the annular cavity and located at one side of the rotating column 3022, and the pushing rod 3024 is circumferentially slidably installed in the annular cavity and located at the other side of the rotating column 3022, when the air inlet pipe 3026 is in the air inlet state, the air pressure of the annular cavity on the side of the air inlet pipe 3026 will increase, thereby extruding and moving the pushing rod 3024 to the annular cavity on the other side, and the gas in the annular cavity on the other side will be discharged through the air outlet pipe 3027, so as to drive the rotating column 3022 to rotate through the pushing rod 3024, thereby driving the horizontal frame 303 and the automobile parts to rotate in the electrophoresis tank, facilitating the separation of bubbles and ensuring the quality of electrophoretic coating.

[0051] As shown in the figure, Figures 9-10 The specific structure of the lifting vibration mechanism 5 of the application is disclosed, the lifting vibration mechanism 5 comprises two cylinder barrels 501 fixedly connected at the top of the circular frame 3021, the two cylinder barrels 501 are both slidably inserted with a sliding rod 502 connected with the hanging rod 301, the bottom of the sliding rod 502 is fixedly connected with a piston block 503 slidably installed in the cylinder barrel 501, the cylinder barrel 501 is installed with a vibrating piece 504 for driving the sliding rod 502 to move up and down, the vibrating piece 504 drives the sliding rod 502 to move up and down in the cylinder barrel 501, thereby realizing the up and down movement of the rotating disc 302, the sliding rod 502 is guided by the cylinder barrel 501, avoiding the horizontal shaking of the parts, and cooperating with the triangular hook 404 arranged obliquely, the falling of the parts during the up and down vibration can be effectively avoided.

[0052] As shown in the figure, Figures 9-10The specific structure of the vibrating element 504 of the present invention is disclosed. The vibrating element 504 includes a tension spring 5041 fixedly connected between the piston block 503 and the top of the inner cylinder 501. An inflation pipe 5042 and an exhaust pipe 5043 are respectively constructed on both sides of the cylinder 501. A sealing block 5044 is inserted into each of the two exhaust pipes 5043, and a pull handle 5045 is connected between the two sealing blocks 5044. A one-way valve 7 is installed in the inflation pipe 5042. The air passage direction of the one-way valve 7 is towards the inside of the cylinder 501. It should be noted that the inflation pipe 5042 and the exhaust pipe 5043 are both connected between the piston block 503 and the top of the inner cylinder 501. When air is inflated into the cylinder 501 through the inflation pipe 5042, the piston block 503 will move downward. The movement causes the tension spring 5041 to stretch. Then, when the parts enter the electrophoresis tank, the handle 5045 can be manually grabbed to pull the sealing block 5044 away from the exhaust pipe 5043. At this time, the piston block 503 loses pressure, and the tension spring 5041 will quickly return to its original position through elastic force, thereby squeezing the gas in the cylinder 501 and quickly expelling it from the exhaust pipe 5043. Afterward, the tension spring 5041 will reciprocate through compression and stretching due to inertia, thereby driving the cylinder 501 to move up and down relative to the slide rod 502. This causes the automotive parts to vibrate up and down in the electrophoresis tank, allowing the remaining air bubbles to be quickly expelled, saving time and improving the overall electrophoresis efficiency. The up and down movement is less than the length of the triangular hook 404 to prevent the parts from falling off.

[0053] like Figure 7 and Figure 10 As shown, the specific structures of the one-way valve 6 and the one-way valve 7 of the present invention are disclosed. Both the one-way valve 6 and the one-way valve 7 include an annular plate 601 and an annular block 602 connected in the inlet pipe 3026, the outlet pipe 3027, and the inflation pipe 5042. A semi-circular groove 603 is constructed on the side of the annular block 602 facing the annular plate 601. A sealing ball 605 is connected to the annular plate 601 by a support spring 604 and abuts against the semi-circular groove 603. It should be noted that gas can only enter from the annular block 602, thereby squeezing the side of the sealing ball 605 facing the annular plate 601. The airflow can smoothly flow into the annular plate 601 through the semi-circular groove 603. When the airflow flows in from the annular plate 601, it will squeeze the sealing ball 605 against the semi-circular groove 603 to prevent the gas from flowing out.

[0054] like Figure 1The specific structure of the driving component 8 of the present invention is disclosed, and it also includes a driving component 8 for driving the rotating column 3022 to rotate and the piston block 503 to move. The driving component 8 includes an insulating frame 801 fixedly connected to the side of the moving frame 101. An air pump 802 is fixedly connected to the insulating frame 801. A vent pipe 803 is connected between one of the air inlet pipes 3026 and air outlet pipes 3027 on two adjacent rotating disks 302. The vent pipe 803 is used to connect the adjacent rotating disks 302. An inflation hose 804 is connected to the other air inlet pipe 3026. An inflation hose 804 is connected to the other air inlet pipe 3026. A diversion hose 805 is provided to connect all the cylindrical tubes 501. The other ends of the diversion hose 805 and the inflation hose 804 are connected to the air pump 802 via a switching valve 806. When electrophoretic coating is required on automotive parts, the automotive parts are first mounted on the support frame 4. Then, the support frame 4 is installed in the hook groove 305 of the L-shaped vertical plate 304. The suspension frame 3 is then hung on the rectangular hanging frame 1 via the hanging rod 301 and the loading and unloading structure 2 to achieve the loading and unloading of the parts. Finally, the sealing block 5044 is inserted into the exhaust pipe 504. In step 3, air pump 802 and diversion hose 805 are used to inflate all cylinders 501 until piston block 503 contacts the bottom of cylinder 501. Then, the rectangular hanging frame 1 is placed into the electrophoresis tank using a mobile device, and the sealing block 5044 is manually removed, causing cylinder 501 to depressurize. Cylinder 501 and rotating disk 302 move rapidly downward relative to piston block 503 under the influence of gravity and the tension of tension spring 5041. Then, inertia causes tension spring 5041 to rebound, thereby causing the components to vibrate up and down, which accelerates the removal of air bubbles from the components. To save settling time and improve overall efficiency, the electrophoresis tank is then powered on. During electrophoresis, the air pump 802 and the air inflator 804 are used to inflate the circular frame 3021, causing the lever 3024 to drive the rotating column 3022 to rotate, thus rotating and swinging the parts to remove air bubbles stuck on the surface of the parts and improve the quality of electrophoretic coating. After electrophoresis is completed, the parts are lifted above the electrophoresis tank and vibrated again by the lifting and vibration mechanism 5, so that the residual liquid in the part cavity can flow out quickly, so as to quickly enter the next process and improve overall efficiency.
