The first roller assemblies 110 are arranged in parallel, and the driving assembly 120 includes a first driving motor 121 and a synchronous chain belt 122. The first driving motor 121 is linked to the first transmission gears 113 on the plurality of first roller assemblies 110 through the synchronous chain belt 122. When the first driving motor 121 rotates, the synchronous chain belt 122 cooperates with the plurality of first transmission gears 113 to realize synchronous rotation of the plurality of first rotating shafts 111. The material sheet is carried on the plurality of first rollers 112, and the plurality of first rollers 112 rotate synchronously, which can ensure that the material sheet is transmitted in a stable direction, and prevent the material sheet from turning during the transmission process, resulting in inaccurate subsequent positioning.

[0037] The lifting assembly 130 is located at the bottom of the multiple groups of first roller assemblies 110. The lifting assembly 130 includes a first lifting module 131 and a plurality of lifting parts 132 arranged on the top of the first lifting module 131.

The plurality of lifting parts 132 pass through the gap between two adjacent first roller assemblies 110 from bottom to top. The pulley 133 lifts the material sheet, so that the material sheet and the first roller 112 are out of contact with each other, thereby preventing the first roller 112 from continuously transmitting the material sheet.

[0038] The interception assembly 150 includes a second lifting module 151 and a baffle 152 arranged on the top of the second lifting module 151. The interception mechanism 150 is located at the end of the transmission area of ​​multiple first roller assemblies 110; in this embodiment, the baffle 152 is located between the last two groups of first roller assemblies 110, and the second lifting module 151 drives the baffle 152 to rise upward.

The pressure plate 144 is also provided with an avoidance groove 145 that is adapted to the shape of the first roller assembly 110 and the lifting portion 132. The avoidance groove 145 is used to avoid the first roller assembly 110 and the lifting portion 132 to prevent the pressure plates 144 from contacting and blocking each other when driving in opposite or opposite directions. When the two pressure plates 144 are driven in opposite directions, they contact with both sides of the material plate, so that the material plate is driven toward the center direction, thereby realizing secondary positioning, which is convenient for the mechanical equipment to clamp the material plate and transmit it to the flipping mechanism 200.

When the third lifting module 231 drives the movable seat 232 to transmit upward, the connecting rod 233 rotates, and at the same time, the connecting part 202 and the connecting rod 233 rotate, the connecting rod 233 gives the flip frame 202 an oblique upward thrust, and the flip frame 202 rotates with the first rotating rod 203 as the axis to achieve a 90-degree flip; when the third lifting module 231 drives the movable seat 232 to transmit downward, the connecting rod 233 gives the flip frame 202 an oblique downward pulling force, and the flip frame 202 rotates and resets with the rotating rod 203 as the axis, and the material plate is fixed on the flip frame 202, and a 90-degree vertical flip can be achieved through the flip frame 202.

The clamping part 733 of the clamp 40 is unfolded and located at the material plate of the first manipulator 300 through the three-axis transmission module. The fourth propulsion module 701 resets inward, and the clamping part 714 is disconnected from the clamping part 722 on the top of the clamp 700. The clamp 700 uses its own reset mechanism to shrink the clamping part to clamp the material plate, clamp the material plate on the first manipulator 300, and move to above the nickel plating tank 410.

[0063] The nickel plating tank 410 is used to load the chemical liquid, and the material plate is immersed in the chemical liquid for chemical nickel plating. The transmission mechanism 500 includes a fifth lifting module 501, a mounting frame 502 arranged on the top of the fifth lifting module 501, and a transmission component 520 arranged on both sides of the mounting frame 502. The transmission component 520 includes a third driving motor 521, a synchronous wheel (not shown) and a transmission belt 523. The synchronous wheel is rotatably connected to the side of the mounting frame 502. The third driving motor 521 is connected to a driving wheel (not shown). The inner side of the transmission belt 523 is respectively meshed with the driving wheel and the synchronous wheel to form a An annular transmission structure is provided, and a plurality of clamp seats 525 are arranged on the transmission belt 523. The clamp seats 525 are provided with a groove body adapted to the clamp 700. The two sides of the clamp 700 are respectively embedded in the clamp seats 525 corresponding to the two transmission components 520, and the transmission belt 523 is driven to transmit in real time by the rotation of the third driving motor 521. The nickel-plated groove body 510 is located between the two transmission components 520. The clamp 700 is transmitted from left to right, and the material plate is synchronously transmitted in the chemical liquid. The material plate is in full contact with the chemical liquid, so that the nickel molecules are evenly adhered to the material plate, nickel plating is achieved, and the nickel plating effect is improved.

[0064] Furthermore, when the production line needs to stop working, the third drive motor 521 stops rotating, and the fifth lifting module 501 drives the transmission mechanism 500 and the clamp 700 engaged on the transmission mechanism 500 and the material plate to rise upward, so that the material plate is away from the liquid in the chemical nickel plating tank 410, preventing the material plate from being immersed in the chemical liquid for a long time, thereby ensuring the chemical nickel plating effect of the product.

[0065] After the nickel plating is completed, the material plate is driven by the three-axis transmission module and the clamping mechanism to move the clamp 700 and the corresponding clamped material plate close to the second manipulator 800. The second manipulator 800 hooks the material plate, and the clamping part 733 of the clamp 700 is unfolded. The material plate is located to the discharge device through the second manipulator 800; the clamp 700 that does not clamp the material plate is located on the side close to the first manipulator 300, clamps the material plate of the first manipulator 300, and transmits it to the nickel plating device.

[0066] The flipping assembly 900 includes a discharging frame 901 and a receiving member 902 and a propulsion cylinder 903 arranged on the discharging frame 901. The discharging frame 901 is rotatably connected to a second rotating rod 904, the receiving member 902 is fixedly arranged on the second rotating rod 904, the propulsion cylinder 903 is located below the second rotating rod 904, and the fixed end of the propulsion cylinder 903 is rotatably connected to the discharging frame 901, the movable end of the propulsion cylinder 903 is rotatably connected to a second connecting rod 905, and the end of the second connecting rod 905 away from the propulsion cylinder 903 is fixedly connected to the second rotating rod 905, and the discharging assembly includes a plurality of third roller assemblies 906 arranged on the discharging frame 901.

[0067] The receiving part 902 is in a "J" shape. The second robot 800 places the material plate on the receiving part 902, and the thrust cylinder 903 pushes the second connecting rod 905, while driving the receiving part 902 to flip upward with the second rotating rod 904 as the axis. When the material plate is in a horizontal state, the material plate simultaneously contacts with multiple third roller assemblies 906, and the multiple third roller assemblies 906 rotate to complete the discharge.

[0068] The above solution realizes fully automatic chemical nickel plating, which saves manpower and improves production efficiency, improves the uniformity of nickel plating, and improves quality. At the same time, it has the advantage of high adaptability and can process products of different sizes.
