Description

Technical Field

[0001] The present invention relates to the technical field of body pretreatment, and particularly to an electrophoretic rotary turning and dipping conveying device for body pretreatment. Background Technique

[0002] The electrophoretic operation of the body is an important technology for providing protective coating for the body. The body is delivered into the electrophoresis tank through a pipeline-type automatic turning and conveying device until the delivered body is turned in the solution inside the electrophoresis tank. Combined with the action of a DC power supply, the colloidal particles are accelerated to move directionally towards the cathode or anode in the dispersion medium, thereby achieving the purpose of electroplating the body.

[0003] In the current electrophoretic operation of the body, the body mainly uses the turning in the head and tail directions. However, this turning method requires a large amount of space, and the turning amplitude of the head and tail of the body is too large. When the body enters the electrophoresis tank, the solution in the electrophoresis tank will be greatly agitated under pressure. At the same time, the internal structure of the body is complex, so when the solution enters the special-shaped structure inside the body, a bubble cavity will appear. Seriously, due to the bubble problem, the inner wall of the special-shaped structure inside the body cannot be fully immersed in the solution, resulting in poor local electrophoretic effect inside the body. At the same time, after the body is turned and lifted greatly after electrophoresis, the accumulated solution will increase the sputtering range when it falls due to the sharp increase in the height of the body, and it will also cause certain loss of the electrophoretic solution.

[0004] In view of this, an electrophoretic rotary turning and dipping conveying device for body pretreatment is designed to solve the above problems. Summary of the Invention

Detailed implementation manners

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0022] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0023] The following describes a body pre - treatment electrophoresis rotary dipping and conveying device provided by some embodiments of the present invention with reference to the accompanying drawings.

[0024] Embodiment 1: Combined withFigures 1 to 11 As shown in the figure, a body pre-treatment electrophoresis rotary dipping and conveying device provided by the present invention includes a vehicle frame 100, four groups of body calibration mechanisms 500 arranged outside the vehicle frame 100, a ring loading mechanism 400 arranged outside two of the four groups of body calibration mechanisms 500, and the number of the ring loading mechanisms 400 is two. An adaptability-width assisting rotation mechanism 600 is arranged inside the two ring loading mechanisms 400. The adaptability-width assisting rotation mechanism 600 is used to assist in rotating the four groups of body calibration mechanisms 500. A body coordination mechanism 300 is arranged on the two ring loading mechanisms 400, and a beam rail 200 is arranged inside the body coordination mechanism 300. The beam rail 200 is used to provide a lifting platform for conveying the body coordination mechanism 300. The body coordination mechanism 300 is used to provide a platform for free extension for the two ring loading mechanisms 400. The two ring loading mechanisms 400 are used to adapt to both ends of the vehicle frame 100. The four groups of body calibration mechanisms 500 are used to quickly clamp four shaft holes at both ends of the vehicle frame 100 and fix the vehicle frame 100 with the smallest area. The adaptability-width assisting rotation mechanism 600 is used to control the four groups of body calibration mechanisms 500 to rotate self in the inner side of the two ring loading mechanisms 400 and drive the suspended rear vehicle frame 100 to rotate with the smallest amplitude in the electrophoresis tank.

[0025] The ring loading mechanism 400 includes an internal toothed ring 440, an external toothed ring 450, two first ring rails 410 and two second ring rails 420. A ring tooth 430 is arranged on one side of the second ring rail 420 away from the first ring rail 410; The number of the internal toothed ring 440 and the external toothed ring 450 is two. Arc-shaped racks are arranged in the grooves on the inner side of the internal toothed ring 440 and the grooves on the outer side of the external toothed ring 450; Two first feet are arranged on the outer wall of the first ring rail 410, two second feet are arranged on the outer wall of the second ring rail 420, and the first feet and the second feet are fixed by a combined bolt; The body calibration mechanism 500 includes a second slider 520 and a first slider 510 arranged in the inner slideways of the first ring rail 410 and the second ring rail 420, a fifth traction frame 560 movably installed at the outer end of the second slider 520, a sixth traction frame 570 movably installed at the other end of the fifth traction frame 560, a third traction frame 540 movably installed at the outer end of the first slider 510, a fourth traction frame 550 movably installed at the other end of the third traction frame 540, a chuck 580 movably installed between the sixth traction frame 570 and the fourth traction frame 550, and a bushing positioning member 590 arranged inside the chuck 580. A nut 5901 is arranged on the threaded section of the bushing positioning member 590; Pins are installed in the middle of the two second sliders 520. The bottom end of the internal toothed ring 440 is movably installed in the middle of one of the pins, and the bottom end of the external toothed ring 450 is movably installed at the outer end of the other pin; The built-in gear ring 440 and the external gear ring 450 are stacked along the head-tail direction of the vehicle frame 100, and are used to control the synchronous extension and contraction of the two groups of vehicle body calibration mechanisms 500; The number of the bushing positioning members 590 is four, and the four bushing positioning members 590 are used for adaptively clamping four shaft holes at the head end and the tail end of the vehicle frame 100; The third towing frame 540 and the fifth towing frame 560 have the same structure, and are both composed of two arc-shaped gaskets and two end rods; One end of the bushing positioning member 590 facing the shaft hole of the vehicle frame 100 is provided with a T-shaped insertion rod, and the T-shaped insertion rod is used for adapting to the shaft holes in different models of the vehicle frame 100.

[0026] By using the vehicle body coordination mechanism 300 to fix the two groups of ring loading mechanisms 400, at this time, the two groups of ring loading mechanisms 400 will provide an annular support carrier for the fixation of the vehicle frame 100. When the vehicle frame 100 is inserted by the four bushing positioning members 590 and suspended in the middle of the inner cavities of the two groups of ring loading mechanisms 400, the whole vehicle frame 100 can be fixed in the way of the smallest contact area. After the two groups of ring loading mechanisms 400 are transferred to directly above the electrophoresis tank, the fixed vehicle frame 100 can cooperate with the two groups of ring loading mechanisms 400 to enter the electrophoresis tank with the smallest amplitude. As the vehicle frame 100 is completely immersed in the electrophoresis solution, the circumferential rotation of the four groups of vehicle body calibration mechanisms 500 is driven by the width-adjusting and assisting rotation mechanism 600. At this time, the vehicle frame 100 can rotate uniformly inside the electrophoresis solution. This process can avoid excessive head-tail flipping of the vehicle frame 100 and prevent the electrophoresis solution from overflowing due to pressure, and at the same time, it can improve the full coverage of the complex cavity structure inside the vehicle frame 100 by the electrophoresis solution.

[0027] Embodiment 2: Combined with Figure 3 、 Figure 8 And Figure 9 As shown, on the basis of Embodiment 1, the number of the first ring rail 410 and the second ring rail 420 is four, and two adjacent first ring rails 410 and two adjacent second ring rails 420 form a circular track; The vehicle body coordination mechanism 300 includes a sliding seat 310 movably installed outside the beam rail 200, a hydraulic component 320 fixedly installed in the middle of the sliding seat 310, two stability-enhancing covers 330 movably installed at both ends of the sliding seat 310, a first towing frame 340 movably installed at the inner ends of the stability-enhancing covers 330, and an end plate 350 movably installed at the adjacent end heads of the two first towing frames 340; Four grooves are opened at the bottom of the outer end of the stability-enhancing cover 330, and the four grooves are used for limiting and constraining the tops of two adjacent first ring rails 410 and two adjacent second ring rails 420; The body coordination mechanism 300 controls the lateral extension of two sets of ring loading mechanisms 400 for adapting to the head end and the tail end of the vehicle frame 100.

[0028] Preferably, the sliding seat 310 is composed of a sliding table, an oval cushion plate, and two U-shaped outer frames, and two stability-enhancing cover plates 330 are movably installed on the two U-shaped outer frames, while the hydraulic component 320 is fixedly installed in the middle of the oval cushion plate; When the sliding table is horizontally moved along the beam rail 200 by an external driving device, along with the regular lifting movement of the beam rail 200, the entire driven sliding seat 310 can finally drive two sets of ring loading mechanisms 400 and the fixed vehicle frame 100 to enter and exit the electrophoresis tank. After the hydraulic component 320 operates, the internal hydraulic sub-rod thereof will push the end plate 350 to lift or lower. Finally, the two first traction frames 340 and the stability-enhancing cover plates 330 obtained by traction will drive two sets of ring loading mechanisms 400 to quickly adapt to vehicle frames 100 of different lengths.

[0029] Embodiment 3: Combined with Figures 4 to 11 As shown, on the basis of Embodiment 1, the body calibration mechanism 500 further includes two second traction frames 530, and the two second traction frames 530 are respectively movably installed in the middle of the two first sliders 510.

[0030] Preferably, the length of the second traction frame 530 is the same as the length of the inner arc-shaped gaskets of the third traction frame 540 and the fifth traction frame 560, and the two second traction frames 530 are used to control the initial height of the two first sliders 510.

[0031] The width-adjusting and assisting rotation mechanism 600 includes four support plates 640, and the tops of the two second traction frames 530 are respectively connected to two of the support plates 640. There are tail bases 620 provided at the bottoms of two of the support plates 640, head bases 630 provided at the bottoms of the other two support plates 640, a cross beam 610 movably installed outside the sliders at the bottoms of the head bases 630, and the tail bases 620 are fixedly installed at the other end of the cross beam 610. There are two clamping plates 650 fixedly installed at the top of the other end of the cross beam 610, a sliding gear 660 movably installed inside the two clamping plates 650, a position control motor 670 fixedly installed inside the head base 630, an extended shaft rod 680 installed at one end of the transmission shaft inside the position control motor 670, and the sliding gear 660 is movably installed outside the extended shaft rod 680, and the other end of the transmission shaft inside the position control motor 670 is installed with a fixed gear 690; The inside of the sliding gear 660 is provided with a cross-shaped jack, the outer wall of the extended shaft rod 680 is provided with a cross-shaped protrusion, and the sliding gear 660 slides along the outside of the extended shaft rod 680, for providing stable kinetic energy for the two sets of extended ring loading mechanisms 400; Preferably, two support plates 640 are fixed to both ends of the tail base 620 by welding. Here, the two support plates 640 form a U-shaped structure due to the tail base 620. The other two support plates 640 are also fixed to the head base 630 by welding. When the position control motor 670 is started, the internal transmission shaft thereof will rotate in cooperation with the lengthening shaft rod 680. At this time, the fixed gear 690 installed at the other end of the transmission shaft inside the position control motor 670 and the sliding gear 660 at the other end of the lengthening shaft rod 680 will be driven at the same speed. At this time, the two sets of ring loading mechanisms 400 can be freely extended and then can be provided with stable kinetic energy by the fixed gear 690 and the sliding gear 660, so as to ensure the constant extension angle of the two internal toothed rings 440 and the two external toothed rings 450.

[0032] The other end of the cross beam 610 is fixedly installed with a machine cover 6101. A rotary motor 6102 is installed inside the machine cover 6101, and a toothed disk 6103 is installed on the transmission shaft inside the rotary motor 6102. The toothed disk 6103 rotates circumferentially along the two closed ring teeth 430, and is used to drive the whole width-adjusting auxiliary rotation mechanism 600 and the four groups of vehicle body calibration mechanisms 500 to rotate.

[0033] Preferably, the end of the inner side of the machine cover 6101 is fixed to the cross beam 610 by two rivets. When the rotary motor 6102 operates, the internal transmission shaft thereof will rotate at a constant speed in cooperation with the toothed disk 6103. Finally, the toothed disk 6103 will uniformly surround along the two ring teeth 430 on the outer sides of the adjacent group of internal toothed ring 440 and external toothed ring 450, so as to ensure that the vehicle frame 100 fixed by the four groups of vehicle body calibration mechanisms 500 can be flipped with the smallest amplitude in the electrophoresis solution.

[0034] The fixed gear 690 is arranged in the two arc-shaped racks of one group of internal toothed ring 440 and external toothed ring 450. The sliding gear 660 is arranged in the two arc-shaped racks of the other group of internal toothed ring 440 and external toothed ring 450.

[0035] The working principle and usage process of the present invention: First, the position control motor 670 is operated. As the transmission shaft inside the position control motor 670 rotates reversely, the fixed gear 690 installed at one end of the internal transmission shaft and the sliding gear 660 movably installed on the lengthening shaft rod 680 will be driven simultaneously. At this time, the two internal toothed rings 440 and the two external toothed rings 450 symmetrically distributed in the two sets of ring loading mechanisms 400 will be respectively driven by the fixed gear 690 and the sliding gear 660. As the bottom ends of the inner gear ring 440 and the outer gear ring 450 approach each other, the two second sliders 520 provided at the bottoms of the inner gear ring 440 and the outer gear ring 450 will continuously approach. Then, the two sleeve positioning members 590 symmetrically distributed horizontally will be compressed and extend outwards. Next, the frame 100 is delivered to the gap in the middle of the two sets of ring loading mechanisms 400 by the conveying device. According to the vehicle length of the frame 100, the hydraulic component 320 is operated. At this time, the internal hydraulic sub-rod will push the end plate 350 to rise and fall, and the two first traction frames 340 movably mounted on the end plate 350 will push the two stability-increasing cover plates 330 to relatively extend along the slide base 310. Finally, the two sets of ring loading mechanisms 400 can adapt to the head end and the tail end of the frame 100 until the two sets of sleeve positioning members 590 in the two sets of ring loading mechanisms 400 are symmetrically adapted to the shaft holes at the head end and the tail end of the frame 100; Then, the positioning control motor 670 is operated to rotate forward again until the inner gear ring 440 and the outer gear ring 450 contract relatively. Then, the two second sliders 520 provided at the bottoms of the inner gear ring 440 and the outer gear ring 450 will be pulled up. At this time, the two sleeve positioning members 590 symmetrically distributed will be quickly inserted into the shaft holes of the frame 100 under the lateral extrusion force. After the four shaft holes at the head end and the tail end of the frame 100 are quickly inserted by the four sleeve positioning members 590, they will be located at the center position of the two sets of ring loading mechanisms 400. At this time, the frame 100 can be suspended in the minimum contact state; As the entire body coordination mechanism 300 is externally driven to move horizontally along the beam rail 200 at a constant speed to the position directly above the electrophoresis tank, by lowering the entire beam rail 200, the suspended frame 100 can then be immersed into the solution inside the electrophoresis tank. As the frame 100 is completely immersed in the electrophoresis tank, the rotary circular motor 6102 can be operated. As the transmission shaft in the rotary circular motor 6102 rotates forward, the gear disk 6103 installed at the top end of the transmission shaft in the rotary circular motor 6102 will run and rotate along the outside of the two closed second ring rails 420. After the two second ring rails 420 are closed, the two ring teeth 430 provided on the outside thereof will form a closed ring tooth structure. Finally, the gear disk 6103 will rotate along the two closed ring teeth 430 until the entire width-adjusting auxiliary rotation mechanism 600 is compressed and rotates along the annular cavity of the two sets of ring loading mechanisms 400. Finally, the suspended frame 100 can rotate inside the electrophoresis tank. This process can perform electrophoresis operations on the frame 100 in the smallest space, and at the same time reduce the problem that the pressure on the solution in the electrophoresis tank increases due to the head and tail reversal of the current frame 100, thereby avoiding the problem of the solution in the electrophoresis tank overflowing due to excessive flipping pressure of the frame 100.
