[0001] The utility model relates to the technical field of workpiece processing equipment, and particularly relates to a production equipment for fully automatic dacromet dip coating and rust prevention. Background Art

[0002] At present, large workpieces are usually applied in special equipment such as offshore wind turbines, for example, bolts of model M64. Such large workpieces need to undergo dacromet dip coating process. Dacromet dip coating is a new surface treatment technology, also known as "green electroplating". It mainly consists of zinc powder, aluminum powder, chromic acid and deionized water. Through a series of process flows, including degreasing, surface oxide layer treatment, multi-alloy co-permeation, cooling, shot blasting, passivation, dipping or spraying dacromet solution, and sintering and curing oxidation-reduction at a temperature of about 300°C, a protective coating is finally formed on the surface of the workpiece to improve the corrosion resistance and stability of the workpiece.

[0003] However, since the dacromet coating contains chromium ions, especially hexavalent chromium ions, which are harmful to the environment and human body to a certain extent. Therefore, a device capable of automatically performing dacromet dip coating process on workpieces is needed. At the same time, work efficiency and the reliability of dip coating treatment on the surface of workpieces also need to be ensured. Summary of the Utility Model

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] It should be understood that although the terms upper, middle, lower, top, one end, etc. appear in this text to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for easy understanding, rather than to define any directional or sequential limitations.

[0043] As Figures 1-9 shown, a fully automatic dacromet dip coating and rust prevention production device includes:

[0044] A carrier plate 1, on which workpieces 2 are accommodated and arranged;

[0045] A conveyor line 3 for conveying the carrier plate 1, and the conveyor line 3 includes a primary dip coating station 4 and a secondary spraying station 5 arranged in sequence along the conveying direction;

[0046] The first dip coating station 4 includes a dip coating barrel 4.1 and a centrifugal barrel 4.2. A barrel cover is provided on the centrifugal barrel 4.2. The dip coating barrel 4.1 contains a dacromet solution. The centrifugal barrel 4.2 dries the workpiece 2 after dip coating. Above the first dip coating station 4, there is a first gantry 4.3 arranged along the conveying direction. A carrier plate clamping assembly 6 is provided on the first gantry 4.3. The first gantry 4.3 is connected with a multi-axis moving module 14. By means of the carrier plate clamping assembly 6, the carrier plate 1 is grabbed, so that the first gantry 4.3 clamps and transports the carrier plate 1 into the dip coating barrel 4.1, the centrifugal barrel 4.2 and the second spraying station 5 in sequence.

[0047] The second spraying station 5 includes a second treatment chamber 5.1, a spraying assembly 5.2 arranged in the second treatment chamber 5.1, a lifting and transferring module 7 arranged at the bottom and on both sides of the second treatment chamber 5.1, and a second gantry 5.3 arranged along the conveying direction. The second gantry 5.3 is connected with a multi-axis moving module 14. A workpiece clamping assembly 8 is provided on the second gantry 5.3. The second gantry 5.3 is used to transport the workpiece 2 on the carrier plate 1 through the second treatment chamber 5.1 and the lifting and transferring module 7.

[0048] Among them, the multi-axis moving module 14 is used to provide the actions of the carrier plate clamping assembly 6 on the first gantry 4.3 and the workpiece clamping assembly 8 on the second gantry 5.3 in the conveying direction, the vertical direction and the vertical rotation direction. The multi-axis moving module 14 is a conventional technical means in the art and will not be elaborated here.

[0049] In the first dip coating station 4, the first gantry 4.3 immerses the carrier plate 1 loaded with the workpiece 2 in the dip coating barrel 4.1 to ensure that hexavalent chromium and the steel substrate fully react to form a stable purification film. After being immersed for a specified time, then the first gantry 4.3 grabs the carrier plate 1 again and places the carrier plate 1 in the centrifugal barrel 4.2, and the centrifugal barrel 4.2 dries the carrier plate 1 and the workpiece 2 on the carrier plate 1 to ensure that there is no liquid accumulation, hanging liquid, bubbles or missed coating on the workpiece. Then the first gantry 4.3 grabs the dried carrier plate 1 and moves it to the second spraying station 5.

[0050] In the second spraying station 5, the lifting and transferring module 7 includes a transfer belt 7.1 arranged at the bottom of the second treatment chamber 5.1 and lifting platforms 7.2 arranged at the front and rear ends of the transfer belt 7.1. The lifting platforms 7.2 move between the second treatment chamber 5.1 and the transfer belt 7.1. The first gantry 4.3 grabs the carrier plate 1 to the front lifting platform. Then the second gantry 5.3 grabs the workpiece 2 in the carrier plate 1 through the workpiece clamping assembly 8 and enters the second treatment chamber 5.1. At this time, the empty carrier plate 1 descends to the position of the transfer belt 7.1 through the front lifting platform 7.2 and is transported to the rear lifting platform 7.2 through the transfer belt 7.1. Then the rear lifting platform 7.2 rises to receive the workpiece 2 after the second spraying treatment. Among them, the second gantry 5.3 grabs the workpiece 2 after the second treatment spraying and places it on the empty carrier plate 1.

[0051] As a further implementation of the spraying component 5.2, the secondary treatment chamber 5.1 is arranged perpendicular to the moving direction of the secondary truss 5.3. The spraying component 5.2 includes a treatment rack 5.21 arranged in the secondary treatment chamber 5.1. The treatment rack 5.21 is movably arranged along the length direction of the secondary treatment chamber 5.1. An output pipe 5.22 arranged along the length direction of the workpiece 2 is provided on the treatment rack 5.21. The output pipe 5.22 is used to output dacromet solution and / or cleaning gas. Among them, the number of output pipes 5.22 is multiple and is arranged with respect to the length direction of the workpiece 2.

[0052] Specifically, the length of the secondary treatment chamber 5.1 matches the length of the workpieces 2 arranged on the carrier plate 1, and the length of the action end of the workpiece clamping component 8 matches the length of the arranged workpieces 2, so that the transfer of the entire column of workpieces 2 in the carrier plate 1 can be completed through one clamping action.

[0053] As Figure 8 shown, preferably, the number of treatment racks 5.21 in the secondary treatment chamber 5.1 is two, and an in-chamber moving module 5.7 is provided at the top of the secondary treatment chamber 5.1. The moving module can be selected as the driving mode of the lead screw nut, which will not be elaborated here too much, or a multi-axis moving module 14, so as to achieve high-degree-of-freedom actions in the secondary treatment chamber 5.1. Among them, the workpieces 2 in the secondary treatment chamber 5.1 are processed by the two treatment racks 5.21 to improve the working efficiency of the spraying treatment.

[0054] As an arrangement mode of the spraying component 5.2, cleaning gas can be output in some of the output pipes 5.22, and dacromet solution spraying can be output in the other part of the output pipes 5.22.

[0055] As an arrangement mode of the spraying component 5.2, dacromet solution spraying can be output in the output pipe 5.22, and at the same time, it can play the role of cleaning the surface of the workpiece 2.

[0056] Continue to refer to Figure 8 , as a further implementation of the secondary treatment chamber 5.1, a plurality of rotating rollers 5.4 are provided at the bottom of the secondary treatment chamber 5.1, and two protective covers 5.5 are arranged at intervals above the rotating rollers 5.4. The rotating rollers 5.4 are parallel to the workpiece 2. A space for placing the workpiece 2 is formed between two adjacent rotating rollers 5.4, and the workpiece 2 is driven to rotate under the action of the rotating rollers 5.4 to cooperate with the treatment rack 5.21 and the output pipe 5.22 above to perform uniform surface spraying treatment on the workpiece 2 and ensure the processing quality.

[0057] Specifically, a vertical gap is provided between the protective cover 5.5 and the rotating roller 5.4, and a traveling space 5.6 for the workpiece clamping module and the moving parts of the secondary gantry 5.3 to pass through is formed between the two protective covers 5.5 arranged at intervals. The secondary gantry 5.3 at least extends above the rear lifting table 7.2 to transfer the workpiece 2 in the secondary treatment chamber 5.1 to the empty carrier plate 1 at the rear end.

[0058] In the secondary spraying station 5, the workpiece clamping module clamps the workpiece 2 between the two rotating rollers 5.4, and the workpiece 2 is placed in a posture parallel to the rotating rollers 5.4.

[0059] In the above embodiment, by applying the spraying of the secondary dacromet solution, it is ensured that the dacromet solution adheres to the surface of the workpiece 2 more uniformly and firmly, and the thickness and uniformity of the coating are precisely controlled, avoiding the situation of uneven thickness or missed coating. By combining the immersion and spraying of the dacromet solution, the performance of the workpiece in terms of anti-corrosion, wear resistance, aesthetics, etc. is comprehensively improved.

[0060] As shown in Figures 1 to 3 In this embodiment, in order to further improve the working efficiency of the workpiece 2 processing, a transfer manipulator 9 is also provided at the conveying end of the conveying line 3, and transfer stations 10 are arranged on both sides of the transfer manipulator 9. A carrier plate clamping assembly 6 is provided on the transfer manipulator 9; the two transfer stations 10 are used for loading the unprocessed full-load carrier plates 1 and receiving the full-load carrier plates 1 processed on the conveying line 3. The transfer manipulator 9 grabs the carrier plate 1 to the transfer station 10 through the carrier plate clamping assembly 6, or takes out the carrier plate 1 from the transfer station 10 to the conveying line 3.

[0061] Preferably, the transfer station 10 includes a linearly arranged transfer track 11 and a transfer table sliding on the transfer track 11. The transfer table is used to carry the carrier plate 1. A linear movement module 6.2 is arranged between the transfer track 11 and the transfer table. In this way, the movement of the transfer table is realized, so as to load and unload materials outside the equipment, which is beneficial to improving the safety of the operators.

[0062] As shown in Figure 9 In an embodiment of the carrier plate 1, the carrier plate 1 includes side plates surrounding the periphery. The upper and lower sides of the carrier plate 1 are open. A support plate 1.1 for spacing and supporting a plurality of workpieces 2 is provided on the carrier plate 1. The support plate 1.1 is arranged at both ends of the workpiece 2 and fixed by the side plates. A card slot 1.2 for cooperating with the moving end of the carrier plate clamping assembly 6 is also provided on the side plate of the carrier plate 1. Of course, in some other embodiments, the carrier plate 1 can also be grabbed and transferred by directly supporting the carrier plate 1 at the bottom.

[0063] Among them, the support plate 1.1 is arranged along the length direction of the carrier plate 1. A first V-shaped groove 1.3 is provided on the support plate 1.1, and the workpiece 2 is positioned through the first V-shaped groove 1.3.

[0064] Preferably, a gap is further provided between the side plate and the end of the workpiece 2, and the Dacromet solution in the dip coating barrel 4.1 can fully contact the end of the workpiece 2 through this gap.

[0065] Referring to Figure 3 and Figure 4 , as an embodiment of the carrier plate clamping assembly 6, the carrier plate clamping assembly 6 includes a connecting seat 6.1, and two groups of linear movement modules 6.2 and two groups of clamping blocks 6.3 oppositely arranged on the connecting seat 6.1. The clamping blocks 6.3 are in transmission connection with the linear movement modules 6.2. The actuation directions of the two groups of linear movement modules 6.2 on the clamping blocks 6.3 are opposite. The linear movement module 6.2 can be selected as the driving mode of the screw nut, so that the two groups of clamping blocks 6.3 move relatively to clamp the carrier plate 1. And a clamping block 6.31 corresponding to the card slot 1.2 is provided on the clamping block 6.3. The carrier plate 1 is stably and reliably transported by clamping the clamping block 6.31 into the card slot 1.2.

[0066] As Figure 6 shown, as an embodiment of the workpiece clamping assembly 8, the workpiece clamping assembly 8 includes clamping plates 8.2 oppositely arranged at both ends of the workpiece 2, and a plurality of clamping heads 8.1 arranged on the clamping plates 8.2. Among them, the number of clamping heads 8.1 on the clamping plates 8.2 is opposite to the number and position of the workpieces 2. A second V-shaped groove 1.4 opposite to the clamping heads 8.1 is provided on the carrier plate 1. Both ends of the workpiece 2 are exposed on the second V-shaped groove 1.4. Through the relative movement of the clamping plates 8.2, the clamping heads 8.1 pass through the second V-shaped groove 1.4 and relatively clamp and release the workpiece 2.

[0067] Preferably, the clamping heads 8.1 can be flexibly arranged, and the distance between the clamping heads 8.1 matches the length of the workpiece 2, and the number of the clamping heads 8.1 matches the number of the workpieces 2.

[0068] Among them, the two oppositely arranged clamping plates 8.2 can be driven by a double-nut screw rod, so that the two clamping plates 8.2 approach or move away relatively.

[0069] From Figures 6 to 8As shown in the figure, specifically, the lifting and transfer module 7 includes a transfer belt 7.1 provided at the bottom of the secondary treatment bin 5.1, and lifting platforms 7.2 provided at the front and rear ends of the transfer belt 7.1. The lifting platforms 7.2 move between the vertical positions of the secondary treatment bin 5.1 and the transfer belt 7.1. And a linear movement module is also provided on the lifting platform 7.2 and arranged towards the secondary treatment bin 5.1 to transfer the carrier plate 1 in the front-rear direction. Among them, the lifting platform 7.2 realizes lifting through a vertically arranged screw-nut mechanism.

[0070] Specifically, a drying channel 12 and / or a cooling channel 13 are also provided at the rear of the conveyor line 3 in the secondary spraying station 5.

[0071] Among them, the carrier plate 1 and the workpiece 2 after secondary treatment enter the drying channel 12. The drying channel 12 evaporates the surface moisture of the workpiece 2 and strengthens the bonding force between the coating and the workpiece 2.

[0072] Among them, by cooling the dried carrier plate 1 and workpiece 2, it helps to form a denser and more uniform coating structure, thereby improving the hardness, wear resistance and corrosion resistance of the coating. On the other hand, it is also beneficial to reduce the deformation of the workpiece 2.

[0073] In some other embodiments, the drying channel 12 and the cooling channel 13 are arranged in parallel. Between the drying channel 12 and the cooling channel 13, and at the position of the conveyor line 3 corresponding to the manipulator, a lifting and transfer module is provided. This lifting and transfer module is used to block the carrier plate 1 on the conveyor line 3 for the manipulator to grab the carrier plate 1, or to load and unload materials after the drying channel 12. At the same time, the lifting and transfer module is also used to transfer the carrier plate on one side of the conveyor line to the other side.

[0074] Among them, the lifting and transfer module includes a top plate, a conveyor chain provided on the top plate, and a lifting cylinder for driving the top plate to lift.

[0075] Preferably, the conveyor chain is connected between two parallel sections of the conveyor line 3.

[0076] Specifically, the conveyor line 3 is arranged in a loop. The transfer manipulator 9 and the transfer station 10 are arranged at the end of the conveyor line 3. In this way, the workpiece 2 can undergo a primary dipping station 4 and a secondary spraying station 5 in a secondary cycle to ensure the surface treatment quality of the workpiece 2.

[0077] In the above embodiments, the primary treatment and secondary treatment of the workpiece 2 are both carried out in the barrel and the bin, which is beneficial to improving the processing quality and reducing the influence of dust and impurities on the coating quality.

[0078] It should be noted that only bolts are shown as workpieces in the specification drawings of the present utility model for surface treatment with Dacromet solution. It can also be other workpieces that need surface treatment.

[0079] This specific embodiment is only an interpretation of the present utility model, and it is not a limitation to the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the Patent Law.
