[0020] Based on the above, reference Figure 1 and 3 As shown, a guide channel is provided near the opening in each working pool 2, and an exhaust gas treatment device 10 is provided in the nickel plating station 1. The exhaust gas treatment device 10 is connected to the guide channel and is used to guide the airflow in the working pool 2 to flow in a specified direction; through the guide channel, the exhaust gas in the working pool 2 is guided to the exhaust gas treatment device 10 for treatment; In a specific embodiment, referring to Figure 3 as shown, the diversion channel includes an air inlet hole 5 located at the opening of the working pool 2 and communicating with the working pool 2, and a diversion chamber 6. The diversion chamber 6 communicates with the air inlet hole 5, and two slopes 7 are arranged in the diversion chamber 6. The two slopes 7 are arranged in an inverted "entry" shape, and a break 8 is arranged near the two slopes 7; the air flow detaches from the diversion chamber 6 through the break 8; and a connection channel 9 for connecting the break 8 and the waste gas treatment device 10; during treatment, the waste gas in the working pool 2 rises to the opening and flows into the diversion chamber 6 through the air inlet hole 5. In the diversion chamber 6, the waste gas first flows along one slope 7, that is, Figure 3 the upper slope 7 in Figure 3 , and the waste gas is guided by this slope 7 to flow to the intersection point of the "entry". The intersection point is the break 8 of the two slopes 7. The waste gas passes through the intersection point and continues to flow along the extension section of the other slope 7, and flows into the connection channel 9.

The air flow recovery channel 12 covers all the working pools 2, and the air flow recovery channel 12 is connected to the waste gas treatment device 10 through a connecting pipe. Through the air flow recovery channel 12, the waste gas overflowing after the door panel 4 is opened can be recovered, so as to realize the all-round waste gas recovery work.

[0022] For the conveying mechanism, referring to Figure 4 as shown, it is arranged above the working pool 2 and includes a circulating slideway 13 and a plurality of sliders 14 arranged in the circulating slideway 13. The function of the circulating slideway 13 is to provide each slider 14 to slide through all the working pools 2. The circulating slideway 13 is an annular slideway, part of which is arranged inside the nickel plating table 1 and part of which faces the working pool 2. Referring to Figure 4As shown, the slideway and the slider 14 facing the working pool 2 are shown, and the slider 14 can reciprocate on each working pool 2 along the circulating slideway 13, and each slider 14 slides synchronously, and each slider 14 is installed with a clamping structure; the clamping structure can clamp the hanger 21 for transportation between each working pool 2; For the transportation of the rack 21 between the conveying mechanism and the working pool 2, in this embodiment, a transfer mechanism is installed on one side of each working pool 2. Figure 5-Figure 6 As shown, the transfer mechanism includes a pallet and a sliding structure. The pallet is used to support the rack 21, and the pallet is configured to be spliced ​​with the rack 21 in the horizontal direction when it goes deep into the working pool 2; the sliding structure is connected to the pallet, and is used to drive the pallet to go deep into the working pool 2 or move toward the conveying mechanism. In a specific embodiment, reference Figure 3 , Figure 7-Figure 8 As shown, the support plate is mainly composed of two symmetrically arranged support rods 15, the sliding structure includes a screw rod 16 arranged in the vertical direction, and a sliding block 17 with a screw rod 16 nut arranged on the screw rod 16, and through holes 18 are opened on the sliding block 17 corresponding to the two support rods 15, and the ends of the support rods 15 pass through the through holes 18 and are slidably arranged in the through holes 18 along the horizontal direction; grooves 19 are opened on both sides of the working pool 2 in the vertical direction, and a top block 20 is arranged in at least one groove 19, and the top block 20 is configured to squeeze the two support rods 15 to move away from each other when the two support rods 15 enter the groove 19; and a splicing block 25 is installed on each support rod 15, and the top of the hanger 21 is an inverted "mountain" shape structure, and the two support rods 15 are respectively inserted into the two notches 22 of the "mountain" structure, and splicing holes 26 are opened in the notches 22 and at the positions of the splicing blocks 25.

[0023] The screw rod 16 is equipped with a driving motor or other power source to drive the screw rod 16 to rotate, thereby driving the sliding block 17 to move up and down. When moving up, it moves to the clamping structure to support the hanger 21 released from the clamping structure, that is, the two support rods 15 are placed in the two notches 22 of the "mountain"-shaped structure of the hanger 21 to lift the hanger 21. As the screw rod 16 is driven, the support rod 15 and the hanger 21 are driven to move down into the working pool 2. As the support rod 15 moves down, it will contact the top block 20, and the top block 20 is a cone-like structure, which gradually drives the two support rods 15 to move away from each other, thereby driving the splicing block 25 to be inserted into the corresponding splicing hole 26, realizing the splicing between the support rod 15 and the hanger 21, and stably fixing the hanger 21 on the support rod 15 for corresponding processing work; refer to Fig. 9As shown, a square frame 23 may be sleeved on each support rod 15, and the square frame 23 is used to limit the two support rods 15 from sliding in a direction away from each other, so that the two support rods can move stably. Corresponding to the separation between the support rod 15 and the hanger 21, an elastic structure 24 may be provided in the square frame 23, and the elastic structure 24 is used to drive the two support rods 15 to move closer to each other, that is, when the support rod 15 moves upward and gradually separates from the top block 20, the two support rods 15 can be driven to reset closer to each other under the action of the elastic structure 24, and the splicing block 25 is separated from the splicing hole 26, so as to facilitate the subsequent transfer of the hanger 21 to the clamping structure; In a specific embodiment, based on the above, in this embodiment, a vibration structure is further provided, which is configured to drive the support plate deep in the working pool 2 to vibrate in the horizontal direction; Figure 7-Figure 8 As shown, the end of the support rod 15 passes through the through hole 18 and extends to one side of the vibration structure. The vibration structure includes a vibration motor 27. A cam 28 is installed at the end of the vibration motor 27. The cam 28 is configured to periodically squeeze the support rod 15 when rotating; Figure 7-Figure 8 As shown, vibration structures are provided at both ends of the support rod 15, and the cams 28 of the two vibration structures rotate staggered. On the one hand, the cam 28 is driven to rotate by the vibration motor 27 to periodically squeeze the support rod 15, so that the support rod 15 reciprocates in the horizontal direction, and the synchronous bracket 21 realizes vibration. On the other hand, the cam 28 is staggered with the end of the support rod 15 in the initial state, and coincides with the end of the support rod 15 after the top separation. The vibration operation can only be performed when the two support rods 15 are separated, that is, the support rod 15 is stably connected to the bracket 21, so as to avoid vibration when the two support rods 15 are not in place, thereby improving work safety and stability.

[0024] For the clamping structure, in a specific embodiment, based on the above, refer to Fig.10 As shown, the clamping structure includes a U-shaped block 29, a limiting mechanism is arranged in the U-shaped block 29, a connecting rod 33 is arranged on the hanger 21 at a position corresponding to the U-shaped block 29, and the limiting mechanism is configured to lock the connecting rod 33 inserted into the U-shaped block 29, or unlock the connecting rod 33 inserted into the U-shaped block 29; that is, when the connecting rod 33 of the hanger 21 is transferred and inserted into the U-shaped block 29 by the supporting plate, the limiting mechanism locks the connecting rod 33 to separate the hanger 21 from the supporting rod 15, and then the supporting plate is reset, and the clamping structure drives the hanger 21 to be transferred; For further reference, Fig.10As shown, in this embodiment, the limiting mechanism includes at least one cross bar 30 arranged parallel to the opening of the U-shaped block 29, and in this embodiment, there are two cross bars 30, which are symmetrically arranged. The cross bar 30 is slidably installed in the U-shaped block 29, and one end of the cross bar 30 is deeply inserted into the notch 22 of the U-shaped block 29, and a triangular block 32 is installed at the deep end of the U-shaped block 29; a spring 31 is arranged on the cross bar 30, and the spring 31 area drives the cross bar 30 to move toward the notch 22 of the U-shaped block 29; a first truncated cone block 34 is installed on the connecting rod 33 toward one end of the U-shaped block 29, and a second truncated cone block 35 is coaxially installed on the connecting rod 33 below the first truncated cone block 34, the first truncated cone block 34 and the second truncated cone block 35 are symmetrically arranged, and the second truncated cone block 35 is slidably installed on the connecting rod 33; The hanger 21 is transferred from the support plate to the clamping structure: the support plate moves up, and the connecting rod 33 is inserted into the U-shaped block 29. At this time, the upward movement distance is controlled to be the first distance, and the first truncated cone block 34 contacts the triangular blocks 32 on both sides. The triangular blocks 32 compress the crossbar 30 to move to both sides until the triangular block 32 is located between the first truncated cone block 34 and the second truncated cone block 35, and the triangular block 32 is inserted under the first truncated cone. At this time, the upward movement is completed, and the first truncated cone block 34 can be hung on the two triangular blocks 32; The hanger 21 is transferred from the clamping structure to the support plate: the support plate moves up, and the upward movement distance is controlled to be the second distance. The support rod 15 is inserted into the two notches 22 of the "mountain" shaped structure to lift the hanger 21 and continue to drive the hanger 21 to move upward. At this time, under the action of the second truncated cone block 35, the two triangular blocks 32 will be pushed to compress the cross bar 30 to move to both sides. The two triangular blocks 32 contact the second truncated cone block 35, and the support plate starts to move downward. Since the second truncated cone block 35 is slidably installed on the connecting rod 33, the second truncated cone block 35 will be synchronously moved up to contact with the first truncated cone under the clamping action of the two triangular blocks 32. Through the cooperation of the first truncated cone block 34 and the second truncated cone block 35, the two triangular blocks 32 will automatically disengage from the first truncated cone block 34 and the second truncated cone block 35, so that the connecting rod 33 is separated from the clamping structure; By repeating the above operation, the transfer of the hanger 21 can be completed. There is no need to set a power structure on the clamping structure. Only the upward movement distance of the working pallet is controlled. The operation is simple and the work efficiency is improved.
