An installation frame and a conveyor belt are arranged inside the passivation tank, and lifting mechanisms for lifting the installation frame are arranged on both sides of the passivation tank. By setting the connecting column, the connecting column can move along with the sliding frame and the connecting plate, so that the connecting column can penetrate through the gaps of the conveyor belt, increasing the partial distance between the conveyor belts, thereby accelerating the flow of the electrolyte from the conveyor belt.

Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel passivation, and in particular to an electrochemical passivation treatment device for stainless steel. Background Art

[0002] Electrochemical passivation is to use stainless steel as the anode and place it in the electrolyte. Through the action of current, an oxidation-reduction reaction occurs on the surface of the stainless steel to form an oxide film. The time of electrochemical passivation is relatively short, generally between dozens of minutes and several hours. The passivation film should form a uniform and dense covering layer on the entire surface of the stainless steel to provide effective anti-corrosion protection. If the passivation film is uneven or has pores, local corrosion will occur, thereby reducing the service life of the stainless steel.

[0003] When performing stainless steel passivation treatment, the stainless steel workpiece needs to be placed in the passivation tank, and the electrolyte is injected into the passivation tank and current is applied. However, the stainless steel workpiece is generally in a stationary state when placed in the passivation tank, and the fusion effect with the electrolyte is poor, resulting in uneven passivation. Moreover, when performing electrochemical passivation, a passivating agent needs to be added to the electrolyte, and the passivating agent is not fully fused inside the electrolyte, further reducing the passivation effect. In addition, after the workpiece is passivated, it is necessary to remove the residual passivation solution and ensure the stability of the passivation film. In the prior art, the workpiece is directly fished out, and the passivation solution on the surface of the workpiece directly drips onto the ground, causing waste and having a poor effect on removing the passivation solution of the workpiece, which is not convenient for actual use.

[0039] Refer to Figure 1-11, a stainless steel electrochemically passivating treatment device, including a passivation tank 1. Inside the passivation tank 1, there is an installation frame 3 and a conveyor belt 9. On both sides of the passivation tank 1, there are lifting mechanisms 2 for lifting the installation frame 3. On the surface of the installation frame 3, there are four groups of driving rollers 4. The conveyor belt 9 is sleeved on the surface of the four groups of driving rollers 4. On the surface of the installation frame 3, there are a support plate 8 and a vibration mechanism 7. During the vibration process, the vibration mechanism 7 can mix the electrolyte. The surface of the support plate 8 is evenly provided with drain grooves 81. The conveyor belt 9 contacts the top of the support plate 8 to achieve the state where the support plate 8 supports the conveyor belt 9. The vibration mechanism 7 includes a connecting plate 71 and a sliding frame 75. The sliding frame 75 and the connecting plate 71 are slidably connected. At the positions near the four corners of the top of the connecting plate 71, thickening blocks 73 are fixedly installed. On the top of the sliding frame 75, connecting columns 74 are evenly fixedly installed. The conveyor belt 9 is set in a strip shape and is evenly sleeved on the surface of the four groups of driving rollers 4. The connecting columns 74 are arranged between two adjacent conveyor belts 9. On the surface of the installation frame 3, there is a driving mechanism 5 for driving the vibration mechanism 7 and the conveyor belt 9 to operate. During use, first, use the lifting mechanism 2 to lift the entire installation frame 3 upward, then place the stainless steel workpiece on the conveyor belt 9 on the surface, and then use the lifting mechanism 2 to move the entire installation frame 3 downward again, so that the stainless steel workpiece on the conveyor belt 9 can be immersed in the electrolyte. At this time, use the driving mechanism 5 to drive the vibration mechanism 7 to work. When the vibration mechanism 7 is working, it will use the connecting plate 71 and the sliding frame 75 to make the connecting columns 74 on the surface move upward intermittently. When moving upward, it can penetrate the gap between two adjacent conveyor belts 9. After penetrating, the connecting columns 74 will directly push against the workpiece, causing the workpiece to be stressed and move or flip, thereby improving the contact effect between the workpiece and the electrolyte, and also helping to separate the stacked workpieces, further improving the contact between the workpiece and the electrolyte. The provided support plate 8 is located at the bottom of the conveyor belt 9, which can support the conveyor belt 9, reducing the phenomenon of deformation of the conveyor belt 9 caused by the gravity of the workpiece. Moreover, when the driving mechanism 5 drives the connecting plate 71 to move upward, it will contact the support plate 8, causing the support plate 8 to suddenly be stressed and vibrate upward, so that the workpiece on the conveyor belt 9 vibrates. Therefore, the workpiece on the conveyor belt 9 will not only be vibrated by the support plate 8 but also be moved upward by the connecting columns 74. Moreover, the vibration of the support plate 8 and the reciprocating upward pushing of the connecting columns 74 are both operated by controlling the connecting plate 71, enhancing the practicability and functionality of the device. Similarly, when the workpiece is passivated, use the lifting mechanism 2 to lift the entire installation frame 3 upward by a certain distance to make it away from the liquid level of the electrolyte, and then use the driving mechanism 5 to drive the connecting plate 71 and the sliding frame 75 to move again, so that the connecting columns 74 push the workpiece from below again to make some workpieces can be flipped and use the connecting plate 71 to vibrate the support plate 8, causing the support plate 8 to drive the workpiece on the conveyor belt 9 to vibrate, which can accelerate the detachment of the residual electrolyte on the workpiece from the workpiece. The connecting columns 74 continuously pass through the gaps between adjacent conveyor belts 9,When passing through, the partial spacing between the conveyor belts 9 can be increased, so that the electrolyte can flow down from the conveyor belts 9 more quickly. Since the connecting columns 74 are evenly distributed and there is a certain distance between adjacent connecting columns 74, and the conveyor belts 9 have the ability to deform, when the connecting columns 74 penetrate between the two conveyor belts 9, only slight deformations will occur on both sides of the conveyor belts 9, and the workpieces will not leak from the deformed positions.

[0040] Furthermore, the mounting frame 3 includes a cross-shaped connecting frame 31. Both arms of the cross-shaped connecting frame 31 are provided with a first vertical hole 34 and a second vertical hole 35. Second convex blocks 82 are fixedly installed on both sides of the support plate 8, and the second convex blocks 82 are slidably connected to the second vertical holes 35. First convex blocks 72 are fixedly installed on both sides of the connecting plate 71, and the first convex blocks 72 are slidably connected to the first vertical holes 34. Two limit columns 33 are fixedly installed on the surface of the cross-shaped connecting frame 31, and both of the two limit columns 33 slidably penetrate through the connecting plate 71. The mounting frame 3 is used to support each component, so that the conveyor belts 9, the support plate 8, the connecting plate 71 and the sliding frame 75 are all installed on the mounting frame 3, which is convenient for moving the whole up and down, thus facilitating loading and unloading. The first vertical hole 34 can limit the connecting plate 71 to only slide in the vertical direction, and the limit columns 33 can further function to limit the connecting plate 71 to only move in the vertical direction, making the driving mechanism 5 more stable when driving the sliding frame 75 and the connecting plate 71. The second vertical hole 35 can limit the support plate 8 to only move in the vertical direction, so that the support plate 8 can only vibrate in the vertical direction.

[0041] Furthermore, the lifting mechanism 2 includes two cushion blocks 21, which are respectively fixedly installed on both sides of the passivation tank 1. Hydraulic cylinders 22 are fixedly installed on the surfaces of the two cushion blocks 21. Connecting rods 23 are fixedly installed at the output ends of the two hydraulic cylinders 22. The cross-shaped connecting frame 31 includes vertical rods fixedly installed on both sides. Vertical grooves 101 are provided on the two inner walls of the passivation tank 1, and the cross-shaped connecting frame 31 is slidably connected to the passivation tank 1 through the vertical rods and the vertical grooves 101. The two connecting rods 23 are respectively fixedly connected to the two vertical rods. In use of the lifting mechanism 2, the hydraulic cylinders 22 are started, and the hydraulic cylinders 22 drive the connecting rods 23 to move in the vertical direction. The connecting rods 23 drive the mounting frame 3 and the vertical rods to move in the vertical direction, thereby driving the entire conveyor belt 9 and the support plate 8 and other structures to move in the vertical direction, performing the functions of loading, unloading and treating the residual electrolyte of the workpieces.

[0042] Furthermore, the driving mechanism 5 includes a motor 53 and a second driven rotating disk 54. The motor 53 is fixedly mounted on the surface of the vertical rod of the cross-shaped connecting frame 31. The output shaft port of the motor 53 is fixedly mounted with a double rotating disk 51. The interior of the cross-shaped connecting frame 31 is rotatably connected with a rotating shaft 59. The two ends of the rotating shaft 59 are respectively fixedly mounted with a first driven rotating disk 52 and a connecting disk 55. A first transmission belt 57 is provided between the double rotating disk 51 and the first driven rotating disk 52, and the two are connected through the first transmission belt 57. The distance between the connecting disk 55 and the first driven rotating disk 52 is 1 / 4 of the first driven rotating disk 52. A connecting rod 56 is rotatably connected to the side wall of the rotating shaft 59 and near the edge thereof. The connecting rod 56 is rotatably connected to the bottom of the sliding frame 75. A second transmission belt 58 is provided between the double rotating disk 51 and the second driven rotating disk 54, and the two are connected to each other through the second transmission belt 58. An auxiliary mechanism 6 is provided on the surface of the second driven rotating disk 54. When the driving mechanism 5 is in use, the motor 53 is started, and the motor 53 drives the double rotating disk 51 to rotate. The double rotating disk 51 drives the first driven rotating disk 52 to rotate through the first transmission belt 57. 2 drives the rotating shaft 59 to rotate, the rotating shaft 59 drives the connecting plate 55 to rotate, the connecting plate 55 drives the connecting rod 56 to move, and the connecting rod 56 is rotatably connected to the vibration mechanism 7, so that the vibration mechanism 7 can reciprocate in the vertical direction. The double turntable 51 can also use the second transmission belt 58 to drive the second driven turntable 54 to rotate, and the second driven turntable 54 uses the auxiliary mechanism 6 to drive the transmission roller 4 to rotate. The four transmission rollers 4 use the conveyor belt 9 to rotate synchronously, which plays the function of operating the conveyor belt 9. The auxiliary mechanism 6 can be used to control the connection relationship between the transmission roller 4 and the second driven turntable 54, so as to control the movement or stop of the conveyor belt 9. During the electrolysis process and the electrolyte removal process, the conveyor belt 9 can be made to move and stop intermittently, because during the electrolysis and removal process, the connecting column 74 will play the role of shifting the workpiece toward one side. The intermittent operation of the conveyor belt 9 can prevent the workpiece from falling off the conveyor belt 9 under the shifting of the connecting column 74. When unloading, the conveyor belt 9 can be started normally to facilitate the workpiece to be transferred from the conveyor belt 9.

[0043] Further, the driving roller 4 includes a connecting shaft 41, a rubber sleeve 42, and a spacer 43. The rubber sleeve 42 is uniformly fixed on the surface of the connecting shaft 41. The spacer 43 is uniformly arranged between two rubber sleeves 42 and fixedly connected to the connecting shaft 41 to divide the rubber sleeve 42 and the conveyor belt 9. The conveyor belt 9 is sleeved on the driving roller 4, and each conveyor belt 9 corresponds to the rubber sleeve 42 of each connecting shaft 41. Each conveyor belt 9 is divided by the spacer 43, so that each conveyor belt 9 rotates in a fixed position and will not deviate from the track. Moreover, during use, the support plate 8 can not only support the conveyor belt 9 to prevent the conveyor belt 9 from deforming due to the gravity of the workpiece, but also play an up-and-down vibration effect. During the upward vibration process, the conveyor belt 9 will be subjected to a large pulling force. Since the length of the conveyor belt 9 remains unchanged and the positions of the four driving rollers 4 remain unchanged, in order to enable the conveyor belt 9 to cooperate with the upward vibration of the support plate 8, the rubber sleeve 42 is provided with a deformation function. When the conveyor belt 9 is stressed, the force will directly act on the rubber sleeve 42, causing the rubber sleeve 42 to deform, so as to adapt to the deformation of the conveyor belt 9. The rubber sleeve 42 has the ability to recover from deformation, which will not affect normal use. Moreover, the rubber sleeve 42 can increase the friction force between it and the conveyor belt 9, making the operation of the conveyor belt 9 smoother and reducing the phenomenon of conveyor belt slipping.

[0044] Further, the mounting bracket 3 further includes four groups of extension rods 32. The number of each group of extension rods 32 is two, and one driving roller 4 is correspondingly installed. The four groups of extension rods 32 are respectively fixedly installed on both sides of the cross-shaped connecting frame 31 so that the four driving rollers 4 are arranged in a rectangular array.

[0045] Further, the auxiliary mechanism 6 includes a connecting sleeve 61 and a fixed shaft 63. The fixed shaft 63 is fixedly installed on the side wall of the second driven turntable 54. The connecting sleeve 61 is fixedly installed at the end of the connecting shaft 41. The connecting sleeve 61 rotatably penetrates through the extension rod 32. The fixed shaft 63 is rotatably connected inside the connecting sleeve 61. A plug rod 64 is slidably inserted at the end of the fixed shaft 63. A magnet block 67 and a spring 66 are fixedly installed at the port of the plug rod 64 located inside the fixed shaft 63. One end of the spring 66 away from the plug rod 64 is fixedly connected to the inner wall of the fixed shaft 63. An electromagnet 65 is fixedly installed on the inner wall of the fixed shaft 63. A slot 62 adapted to the size of the plug rod 64 is formed in the inner wall of the connecting sleeve 61 so that when the plug rod 64 is inserted into the slot 62, the fixed shaft 63 and the connecting sleeve 61 can rotate synchronously. During the use of the auxiliary mechanism 6, when it is necessary to drive the conveyor belt 9 by the driving roller 4 to operate, the electromagnet 65 is energized, so that there is a large repulsive force between the electromagnet 65 and the magnet block 67, and then the plug rod 64 can be pushed out of the fixed shaft 63, and the plug rod 64 is inserted into the slot 62 of the connecting sleeve 61. At this time, the second driven turntable 54 will drive the fixed shaft 63 to rotate. The fixed shaft 63 will drive the plug rod 64 to rotate. The plug rod 64 will drive the connecting sleeve 61 to rotate. The connecting sleeve 61 will drive the connecting shaft 41 to rotate, so that the entire driving roller 4 rotates. When it is not necessary to use the conveyor belt 9 to operate, the electromagnet 65 can be powered off. At this time, the repulsive force between the electromagnet 65 and the magnet block 67 becomes smaller. Under the pulling force of the spring 66, the plug rod 64 can be pulled out of the slot 62. At this time, when the second driven turntable 54 drives the fixed shaft 63 and the plug rod 64 to rotate, since the plug rod 64 is not in the slot 62, the connecting sleeve 61 will not be driven to rotate.

[0046] Further, the positions of both sides of the connecting column 74 near the top are set as the first inclined surfaces 741, and the position of the front side of the connecting column 74 near the top is set as the second inclined surface 742, and the side of the connecting column 74 away from the second inclined surface 742 is set as a vertical plane so that the top of the connecting column 74 is in a pointed state.

[0047] Furthermore, the connecting plate 71 is arranged in a frame structure. The sliding frame 75 slides horizontally left and right inside the connecting plate 71. The connecting plate 71 slides vertically up and down in the first vertical hole 34 on the surface of the mounting frame 3 through the first bump 72. The purpose of setting the connecting column 74 with a pointed top is to enable it to easily penetrate the gap between the two conveyor belts 9, avoiding the phenomenon that the larger size of the top of the connecting column 74 directly pushes the conveyor belt 9 from the bottom during the penetration process, resulting in damage to the conveyor belt 9. The set second inclined surface 742 can, when the connecting column 74 penetrates the conveyor belt 9 and acts on the bottom position of the workpiece, make it more conducive to turning over the workpiece by using the second inclined surface 742 and the pointed top at the top. At the same time, the connecting column 74 is installed on the sliding frame 75, and the sliding frame 75 is slidably connected to the connecting plate 71. When the connecting rod 56 moves, it directly acts on the sliding frame 75. Moreover, the moving speed of the connecting rod 56 is relatively fast. Therefore, at the moment of movement, the entire sliding frame 75 can be subjected to a horizontal acting force and a vertical acting force. Among them, the horizontal acting force can make the sliding frame 75 move horizontally on the connecting plate 71, thereby driving the connecting column 74 to perform reciprocating motion. The vertical acting force can make the connecting plate 71 perform reciprocating vertical movement in the limiting column 33 and the first vertical hole 34. Among them, when the sliding frame 75 moves to the leftmost side, the rising position of the connecting plate 71 just enables the connecting column 74 to penetrate the gap of the conveyor belt 9. As the connecting plate 71 continues to rise, the entire sliding frame 75 also just slides from the leftmost side to the rightmost side, so that after the connecting column 74 penetrates the conveyor belt 9, it still has a moving distance toward the right. That is, during the process of the connecting column 74 passing through the gap of the conveyor belt 9 to separating from the gap, the top of the connecting column 74 has an arc-shaped movement trajectory. This moving method can enable the connecting column 74 to not only have the function of jacking up the workpiece but also have the function of pushing the workpiece forward, further strengthening the contact between the workpiece and the electrolyte. And during the process of the top of the connecting column 74 rising from the surface position of the conveyor belt 9 to the highest point, the connecting plate 71 just uses the thickening block 73 to contact the support plate 8 from the bottom until it jacks it up to the highest point and then drops, causing the support plate 8 to vibrate.

[0048] Furthermore, the conveyor belt 9 is arranged in a mesh structure. By setting the conveyor belt 9 in a mesh shape, it helps the electrolyte to be quickly discharged, and the mesh structure can compress the mesh voids during the deformation of the conveyor belt 9 when the connecting column 74 penetrates the gap of the conveyor belt 9, achieving the purpose of protecting the conveyor belt 9.

[0049] In summary, during use, first use the lifting mechanism 2 to lift the entire mounting frame 3 upward, then place the stainless steel workpiece on the conveyor belt 9 on the surface, and then use the lifting mechanism 2 to move the entire mounting frame 3 downward again, so that the stainless steel workpiece on the surface of the conveyor belt 9 can be immersed in the electrolyte. At this time, use the driving mechanism 5 to drive the vibrating mechanism 7 to work. When the vibrating mechanism 7 is working, it will use the connecting plate 71 and the sliding frame 75 to intermittently move the connecting column 74 on the surface upward. When moving upward, it can penetrate the gap between two adjacent conveyor belts 9. After passing through, the connecting column 74 will directly push against the workpiece, causing the workpiece to move or flip under force, thereby improving the contact effect between the workpiece and the electrolyte, and helping to separate the stacked workpieces, further improving the contact between the workpiece and the electrolyte. The provided support plate 8 is located at the bottom of the conveyor belt 9, which can support the conveyor belt 9, reducing the phenomenon of deformation of the conveyor belt 9 caused by the gravity of the workpiece. Moreover, when the driving mechanism 5 drives the connecting plate 71 to move upward, it will contact the support plate 8, causing the support plate 8 to suddenly vibrate upward under force, thereby causing the workpiece on the surface of the conveyor belt 9 to vibrate. Therefore, the workpiece on the conveyor belt 9 will not only be vibrated by the support plate 8 but also be moved upward by the connecting column 74. Moreover, the vibration of the support plate 8 and the reciprocating upward pushing of the connecting column 74 are both operated by controlling the connecting plate 71, enhancing the practicality and functionality of the device. Similarly, when the workpiece is passivated, use the lifting mechanism 2 to lift the entire mounting frame 3 upward by a certain distance to make it away from the liquid level of the electrolyte, and then use the driving mechanism 5 to drive the connecting plate 71 and the sliding frame 75 to move again, so as to use the connecting column 74 to push the workpiece from below again to make some workpieces can be flipped and use the vibration of the connecting plate 71 on the support plate 8 to make the support plate 8 drive the workpiece on the surface of the conveyor belt 9 to vibrate, which can accelerate the detachment of the residual electrolyte on the workpiece from the workpiece. The connecting column 74 continuously passes through the gap between two adjacent conveyor belts 9. When passing through, it can increase the partial distance between the conveyor belts 9, thereby accelerating the flow of the electrolyte down from the conveyor belt 9. Since the connecting columns 74 are evenly distributed and there is a certain distance between adjacent connecting columns 74, and the conveyor belt 9 has the ability to deform, when the connecting column 74 penetrates between two conveyor belts 9, only slight deformation will occur on both sides of the conveyor belt 9, and the workpiece will not leak from the deformed position. The mounting frame 3 is used to support each component, so that the conveyor belt 9, the support plate 8, the connecting plate 71 and the sliding frame 75 are all installed on the mounting frame 3, facilitating the up and down movement of the whole, so as to facilitate loading and unloading. The first vertical hole 34 can limit the connecting plate 71 to only slide in the vertical direction, and the limit post 33 can further play the function of limiting the connecting plate 71 to only move in the vertical direction, making the process of the driving mechanism 5 driving the sliding frame 75 and the connecting plate 71 more stable. The second vertical hole 35 can limit the support plate 8 to only move in the vertical direction, so that the support plate 8 can only vibrate in the vertical direction. During the use of the lifting mechanism 2, start the hydraulic cylinder 22,The hydraulic cylinder 22 drives the connecting rod 23 to move in the vertical direction. The connecting rod 23 drives the mounting bracket 3 and the vertical rod to move in the vertical direction, thereby driving the entire conveyor belt 9, the pallet 8 and other structures to move in the vertical direction, serving the functions of loading, unloading and treating the residual electrolyte of the workpiece. During the use of the driving mechanism 5, the motor 53 is started. The motor 53 drives the double turntable 51 to rotate. The double turntable 51 drives the first driven turntable 52 to rotate through the first transmission belt 57. The first driven turntable 52 drives the rotating shaft 59 to rotate. The rotating shaft 59 drives the connecting disc 55 to rotate. The connecting disc 55 drives the connecting rod 56 to move. The connecting rod 56 is also rotationally connected to the vibration mechanism 7. Therefore, the vibration mechanism 7 can perform reciprocating motion in the vertical direction. The double turntable 51 can also drive the second driven turntable 54 to rotate through the second transmission belt 58. The second driven turntable 54 drives the transmission roller 4 to rotate through the auxiliary mechanism 6. The four transmission rollers 4 rotate synchronously through the conveyor belt 9, serving the function of operating the conveyor belt 9. Among them, the auxiliary mechanism 6 can be used to control the connection relationship between the transmission roller 4 and the second driven turntable 54, so as to control the movement or stop of the conveyor belt 9. During the electrolysis process and the process of removing the electrolyte, the conveyor belt 9 can perform intermittent movement and stop. Because during the electrolysis and removal process, the connecting column 74 will push the workpiece towards one side. The intermittent operation of the conveyor belt 9 can prevent the workpiece from falling off the conveyor belt 9 under the push of the connecting column 74. During unloading, the conveyor belt 9 can be normally started to facilitate the transfer of the workpiece from the conveyor belt 9. The conveyor belt 9 is sleeved on the transmission roller 4, and each conveyor belt 9 corresponds to the rubber sleeve 42 of each connecting shaft 41. Each conveyor belt 9 is divided by the partition piece 43, so that each conveyor belt 9 rotates at a fixed position and will not deviate from the track. Moreover, during the use of the pallet 8, in addition to supporting the conveyor belt 9 to prevent the conveyor belt 9 from deforming due to the gravity of the workpiece, it can also produce an up-and-down vibration effect. During the upward vibration process, the conveyor belt 9 will be subjected to a large pulling force. Since the length of the conveyor belt 9 remains unchanged and the positions of the four transmission rollers 4 remain unchanged, in order to make the conveyor belt 9 cooperate with the upward vibration of the pallet 8, the rubber sleeve 42 is provided with a deformation function. When the conveyor belt 9 is stressed, the force will be directly applied to the rubber sleeve 42, causing the rubber sleeve 42 to deform, so as to adapt to the deformation of the conveyor belt 9. The rubber sleeve 42 has the ability to recover from deformation and will not affect normal use. Moreover, the rubber sleeve 42 can increase the friction force between it and the conveyor belt 9, making the operation of the conveyor belt 9 smoother and reducing the phenomenon of transmission slipping. During the use of the auxiliary mechanism 6, when it is necessary to make the transmission roller 4 drive the conveyor belt 9 to operate, the electromagnet 65 is energized, so that there is a large repulsive force between the electromagnet 65 and the magnet block 67, and then the plug rod 64 can be pushed out of the fixed shaft 63, and the plug rod 64 is inserted into the slot 62 of the connecting sleeve 61. At this time, the second driven turntable 54 will drive the fixed shaft 63 to rotate, and the fixed shaft 63 will drive the plug rod 64 to rotate.The insertion rod 64 will drive the connecting sleeve 61 to rotate, and the connecting sleeve 61 will drive the connecting shaft 41 to rotate, thereby causing the entire driving roller 4 to rotate. When it is not necessary to use the conveyor belt 9 to operate, the electromagnet 65 can be powered off. At this time, the repulsive force between the electromagnet 65 and the magnet block 67 will become smaller. Under the pulling force of the spring 66, the insertion rod 64 can be pulled out of the slot 62. At this time, when the second driven turntable 54 drives the fixed shaft 63 and the insertion rod 64 to rotate, since the insertion rod 64 is not in the slot 62, it will not drive the connecting sleeve 61 to rotate. The connecting column 74 is set with a pointed top so that it can easily penetrate the gap between the two conveyor belts 9, avoiding the phenomenon that the larger size of the top of the connecting column 74 will directly push the conveyor belt 9 from the bottom during the penetration process, resulting in damage to the conveyor belt 9. The set second inclined surface 742 can be used to turn the workpiece more effectively when the connecting column 74 penetrates the conveyor belt 9 and acts on the bottom position of the workpiece by using the second inclined surface 742 and the pointed top. At the same time, the connecting column 74 is installed on the sliding frame 75, and the sliding frame 75 is slidably connected to the connecting plate 71. When the connecting rod 56 moves, it directly acts on the sliding frame 75, and the moving speed of the connecting rod 56 is relatively fast. Therefore, at the moment of movement, the entire sliding frame 75 can be subjected to a horizontal force and a vertical force. The horizontal force can cause the sliding frame 75 to move horizontally on the connecting plate 71, thereby driving the connecting column 74 to move reciprocally. The vertical force can cause the connecting plate 71 to move reciprocally in the vertical direction in the limit post 33 and the first vertical hole 34. When the sliding frame 75 moves to the leftmost side, the rising position of the connecting plate 71 just makes the connecting column 74 penetrate the gap of the conveyor belt 9. As the connecting plate 71 continues to rise, the entire sliding frame 75 also just slides from the leftmost side to the rightmost side, so that the connecting column 74 still has a moving distance toward the right after penetrating the conveyor belt 9. That is, during the process of the connecting column 74 passing through the gap of the conveyor belt 9 to separating from the gap, the top of the connecting column 74 moves in an arc-shaped trajectory. This moving method can enable the connecting column 74 to not only have the function of lifting the workpiece but also have the function of pushing the workpiece forward, further strengthening the contact between the workpiece and the electrolyte. When the top of the connecting column 74 rises from the surface position of the conveyor belt 9 to the highest point, the connecting plate 71 just uses the thickening block 73 to contact the support plate 8 from the bottom until it is pushed to the highest point and then falls, causing the support plate 8 to vibrate. By setting the conveyor belt 9 as a mesh, it helps the electrolyte to be discharged quickly.
