Description

Technical Field

[0001] This utility model relates to the field of passivation equipment technology, specifically a clamping mechanism for automatic passivation equipment. Background Technology

[0002] Automatic passivation equipment is a specialized device that integrates automated control technology with metal surface treatment processes. Its core function is to form a dense passivation film on the metal surface through chemical or electrochemical methods, thereby improving the material's corrosion resistance, oxidation resistance, and stability. The clamping mechanism of the automatic passivation equipment is a core component used to fix, position, and transport workpieces (such as scrapers, metal parts, etc.). Its design directly affects the uniformity, efficiency, and product quality of the passivation process. For example, in prior art 1 (Chinese patent application number CN201921297395.0, application date 2019-08-12), a passivation device for tinplate production can automatically scrape off the passivation liquid on the upper surface of the passivated tinplate, saving passivation liquid, protecting the surrounding environment, protecting the safety of equipment and workers, and eliminating the need for manual removal of passivation liquid, saving operation time and reducing operation steps.

[0003] While existing technologies can improve the passivation efficiency of products and save operation time, most passivation processes involve directly placing the product on the surface of the processing plate. However, this direct placement method can lead to loosening and displacement during subsequent passivation processes, thus affecting the passivation efficiency and making it impractical. Therefore, a clamping mechanism for automatic passivation equipment has been proposed to effectively solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping mechanism for an automatic passivation device, in order to solve the problem mentioned in the background art that the current market method of directly placing the product on the surface of the processing plate for passivation processing, but this direct placement method will cause loosening and displacement during the passivation process, thereby affecting the passivation efficiency of the product and having poor practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism for an automatic passivation device, comprising a body and two mounting seats disposed inside the body, wherein two atomizing spray discs for spraying passivation liquid are rotatably mounted below the two mounting seats, wherein the two atomizing spray discs are sealed to a first storage tank via hoses, the first storage tank being positioned above the body, an mounting plate being positioned inside the body, and two positioning clamps being slidably mounted above the mounting plate, with the atomizing spray discs corresponding to the positions above the two positioning clamps, and a gap existing between the mounting plate and the body.

[0006] Preferably, a control panel is mounted on the front side of the machine body, and the control panel is connected to a drive motor via a wiring harness, and the drive motor is located on the left side of the machine body.

[0007] Preferably, the output end of the drive motor is connected to a bidirectional lead screw, which is rotatably mounted inside the mounting plate, and positioning clamps are threaded through both sides of the bidirectional lead screw.

[0008] Preferably, mounting brackets are screwed onto the top of the two positioning clamps, and a first magnet is mounted on the top of the two mounting brackets.

[0009] Preferably, two second magnets are positioned and installed on the outer surfaces of the two atomizing spray discs, and a first magnet is located on the outer side of each of the two second magnets.

[0010] Preferably, the magnetic poles of the first magnet and the second magnet are opposite.

[0011] Preferably, a rotating shaft is fixedly installed on the rear side of the two atomizing spray discs, and a suction disc is fixedly connected to the rear side of the two rotating shafts. The two suction discs are located inside the machine body, and the two suction discs are sealed to a second storage box through a hose. The second storage box is positioned and installed above the machine body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Equipped with positioning clamps, the machine utilizes an internal mounting plate with two slidable positioning clamps mounted on top of it. When passivation treatment is required, the product can be placed on the upper surface of the mounting plate, and then the two positioning clamps can be moved to retract and position the product, preventing it from loosening or shifting during passivation. This improves the efficiency of passivation treatment and enhances practicality.

[0014] Furthermore, when passivation treatment of the product is required, simply start the drive motor through the control panel to rotate the bidirectional lead screw inside the mounting plate. At this time, the rotating bidirectional lead screw will simultaneously drive the two threaded positioning clamps to retract and move, thereby realizing the retraction and clamping treatment of the placed product. This eliminates the need for complicated manual operation steps and saves operation time.

[0015] Equipped with mounting brackets, the machine features two mounting seats inside the main body. Atomizing spray discs are rotatably mounted below these seats. When the passivation liquid stored inside the atomizing spray discs is sealed and delivered to the discs via a hose for atomized spraying and passivation, two retractable positioning clamps simultaneously drive the first magnets located above the mounting brackets and the second magnets located on the outer sides of the two atomizing spray discs to attract and oscillate based on the principle of magnetic attraction. This drives the two atomizing spray discs to oscillate and concentrate the spray, improving the passivation efficiency and enhancing practicality.

[0016] Furthermore, after the two positioning clamps separate and release their clamping position, the two positioning clamps will separate simultaneously, causing the mounting bracket connected above the two positioning clamps to separate the two first magnets from the two second magnets. At this time, the two atomizing spray discs, after being adsorbed and oscillating, can swing and reset under their own gravity, which facilitates the subsequent passivation treatment and improves the passivation treatment efficiency of the product.

[0017] Equipped with suction discs, which are connected to the rear of the two atomizing spray discs via a rotating shaft, the two atomizing spray discs, after being separated and released from their clamping positions, will drive the two suction discs via the two rotating shafts to absorb the residual passivation liquid inside the machine body. The liquid is then transported to the inside of the second storage tank through a hose, thus avoiding waste of the passivation liquid. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution: a clamping mechanism for an automatic passivation device:

[0027] Example 1: To address the problem that existing methods of directly placing products on the surface of a processing plate for passivation processing result in loosening and displacement during subsequent passivation, affecting the efficiency of the passivation process and leading to poor practicality, the following invention is disclosed: a machine body 1, and two mounting seats 15 disposed inside the machine body 1. Two atomizing spray discs 9 for spraying passivation liquid are rotatably mounted below the two mounting seats 15. The two atomizing spray discs 9 are sealed to a first storage tank 2 via flexible hoses. The first storage tank 2 is positioned above the machine body 1. An mounting plate 5 is positioned inside the machine body 1, and two positioning clamps 6 are slidably mounted above the mounting plate 5. The atomizing spray discs 9 are positioned above the two positioning clamps 6. A gap exists between the mounting plate 5 and the machine body 1.

[0028] A control panel 4 is mounted on the front side of the machine body 1, and the control panel 4 is connected to a drive motor 7 via a wiring harness. The drive motor 7 is located on the left side of the machine body 1. The output end of the drive motor 7 is connected to a bidirectional lead screw 8, which is rotatably mounted inside the mounting plate 5. Positioning clamps 6 are threaded through both sides of the bidirectional lead screw 8.

[0029] like Figure 1 As shown, when passivation treatment of the product is required, simply place the product on the upper surface of the mounting plate 5, and then start the drive motor 7 via the control panel 4 to rotate the bidirectional lead screw 8. At this time, the two positioning clamps 6 connected by the outer threads of the bidirectional lead screw 8 will retract and move, so that the two retracted positioning clamps 6 will automatically retract and clamp the placed product for positioning. Figure 2 and Figure 3As shown, this avoids the product from becoming loose or shifting due to passivation, which would affect the efficiency of subsequent passivation processes. It eliminates the need for complex manual steps, saving operation time.

[0030] Example 2 differs from Example 1 in that, during the passivation process of the product in the passivation equipment, the two atomizing spray discs 9 can be driven to swing and spray, allowing the two atomizing spray discs 9 to perform more uniform passivation treatment on the product. Furthermore, the two suction discs 14 can absorb the residual passivation liquid from the atomizing spray into the inner wall of the second storage tank 3, avoiding waste of the passivation liquid. The following is disclosed:

[0031] Mounting brackets 10 are screwed onto the top of the two positioning clamps 6, and first magnets 11 are mounted on the top of the two mounting brackets 10. Two second magnets 12 are positioned on the outer side of the two atomizing spray discs 9, and the outer side of the two second magnets 12 corresponds to the first magnets 11. The magnetic poles of the first magnets 11 and the second magnets 12 are opposite. Rotating shafts 13 are fixedly mounted on the rear side of the two atomizing spray discs 9, and suction discs 14 are fixedly connected to the rear side of the two rotating shafts 13. The two suction discs 14 are located inside the machine body 1. The two suction discs 14 are sealed to the second storage box 3 through a hose, and the second storage box 3 is positioned on the top of the machine body 1.

[0032] When the two positioning clamps 6 passivate the placed product, the two retractable and moving positioning clamps 6 will cause the first magnets 11 set above the two mounting brackets 10 to retract and move, such as Figures 3-5 As shown, the two first magnets 11 will then attract and oscillate with the two second magnets 12 located on the outer side of the two atomizing spray disks 9 through the principle of attraction between opposite magnetic poles, as... Figure 4 As shown, this allows the two atomizing spray discs 9 to swing and concentrate the spray, thereby improving the passivation efficiency of the passivation equipment. After the two positioning clamps 6 separate and release their clamping and positioning, the two reset and swinging atomizing spray discs 9 will drive the two suction discs 14 through the two rotating shafts 13 to absorb the residual passivation liquid inside the machine body 1. Figure 6 As shown, the passivation solution is then transported to the interior of the second storage tank 3 via a hose to avoid waste.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
