Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy processing, in particular to an anodizing device for an aluminum alloy workpiece. Background Art

[0002] In traditional processes, the anodizing process of aluminum alloy workpieces requires steps such as degreasing, neutralization, chemical polishing, anodizing, surface conditioning, dyeing and drying. These steps are mostly carried out in a reaction tank. The worker needs to clamp the aluminum alloy workpiece on the fixture first, and then each time the next process is required, the workpiece in the previous process needs to be taken out of the reaction tank and then transferred to the next reaction tank. However, the solution in the reaction tank will be taken out with the workpiece, which will not only pollute the surrounding environment, but also adhere to the clothes and shoes of the workers, not only polluting the clothes, but also damaging the health of the workers. In addition, the transfer method of workpieces between processes mentioned above has slow processing efficiency and high cost.

[0003] Therefore, we urgently need to design an aluminum alloy workpiece anodizing device that can automatically transfer the workpiece between reaction tanks. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the utility model provides an aluminum alloy workpiece anodizing device which can automatically transfer the workpiece between reaction tanks.

[0005] The technical solution is: an anodizing device for aluminum alloy workpieces, comprising a plurality of reaction pools arranged in sequence, each of the reaction pools having downwardly concave limit grooves on opposite sides of the upper end opening, and a cross bar for hanging a fixture is provided on the upper side of the limit groove; it also includes a driving mechanism for driving the cross bar to move toward the previous reaction pool, which includes a reciprocating slide, a cylinder and two transmission plates, the moving direction of the reciprocating slide is consistent with the arrangement direction of the reaction pool, the two transmission plates are respectively arranged on both sides of the reaction pool, and the transmission plates are synchronously provided with limit grooves relative to each reaction pool, the housing of the cylinder is fixed to the movable end of the reciprocating slide, and the piston rod of the cylinder is connected to the transmission plate, which can drive the transmission plate to rise and fall; the length of the cross bar is greater than the distance between the two transmission plates.

[0006] Furthermore, a frame is provided at the front end of the last reaction pool, the two sides of the frame are inclined, and a connecting rod is provided horizontally at the inclined bottom end. The cross bar for hanging the clamp is moved to the frame and slides down along the inclined side of the frame onto the connecting rod.

[0007] Furthermore, both ends of the crossbar are provided with annular grooves adapted to the inclined sides of the frame and the lap rods.

[0008] Furthermore, the crossbar is provided with a plurality of hanging slots for hanging the clamps along the length direction.

[0009] Furthermore, short rods are provided on both sides of the crossbar, and the short rods are used to hang the clamps, and the maximum distance between the short rods is less than the inner length of the reaction tank.

[0010] Furthermore, a water collecting box is provided at the bottom of the overlapping rod, and a filter is provided in the water collecting box.

[0011] Furthermore, a drying device is installed at the front end of the frame for drying the workpieces placed on the overlapping rods.

[0012] The beneficial effects are: this device moves back and forth through the reciprocating slide, and cooperates with the cylinder to drive the transmission plate to rise and fall, and transfers the cross bar placed on the limit slot of the rear reaction tank forward to the front reaction tank. In addition, the upper end of the reaction tank is provided with a limit slot and a cross bar structure for hanging the clamp, which can provide good support during the workpiece transfer process, making the workpiece more stable during transfer and storage. This device can not only transfer workpieces automatically and efficiently, but also be safe and stable, saving labor costs.

[0013] Furthermore, the device features a frame and a connecting rod at the end, allowing the workpiece to slide naturally into the drying position for easy subsequent operation. The grooves on the crossbar ensure stability and prevent tilting as it moves forward. Furthermore, the water collection tank and filter effectively collect chemical liquids generated during the process, preventing contamination and ensuring a clean working environment. The drying device at the front of the frame dries the workpiece in real time, improving operational continuity and efficiency.

[0014] In addition, by providing multiple hanging slots, the number of workpieces that can be processed in the same batch can be increased.

[0015] In addition, adding short rods can also increase the number of suspended workpieces and improve processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0024] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as the direction of the examples described in the drawings. It is understood that if the device in the illustration is turned upside down, the component described as "upper" will become the component "lower". Other relative terms such as "high", "low", "top", "bottom", "left", "right" and the like also have similar meanings. When a structure is "on" another structure, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" set on the other structure, or that the structure is "indirectly" set on the other structure through another structure. The following is a detailed description of the present invention in conjunction with the drawings and specific embodiments, but it is not intended to limit the present invention.

[0025] like Figure 1The aluminum alloy workpiece anodizing device shown includes a plurality of reaction pools 1 arranged in sequence, and each reaction pool 1 has downwardly recessed limit grooves 11 on opposite sides of the upper end opening. A cross bar 2 is placed in the limit groove 11 on each reaction pool 1, and the cross bar 2 is used to hang the aluminum alloy workpiece fixture 3. In order to realize the automatic transfer of the workpiece in each reaction pool 1, a driving mechanism 4 is also provided. The driving mechanism 4 can drive the cross bar 2 to move toward the previous reaction pool 1. It consists of a reciprocating slide 41, a cylinder 42 and two transmission plates 43, wherein the moving direction of the reciprocating slide 41 is consistent with the arrangement direction of the reaction pool 1, and the reciprocating slide 41 provides a reciprocating driving force in the horizontal direction. The two transmission plates 43 are respectively arranged on both sides of the reaction pool 1, preferably in a symmetrical manner. The transmission plate 43 is synchronously provided with a relative position relative to each reaction pool 1. The limiting groove 11 and the length of the transmission plate 43 can be the same as the total length of the reaction pool 1. The cylinder 42 is arranged in a vertical direction, and the piston rod is facing. The piston rod of the cylinder 42 is connected to the transmission plate 43, which can drive the transmission plate 43 to rise up or fall back down. It should be noted that when selecting the cylinder 42, it is necessary to try to select a cylinder with a stroke greater than the height of the reaction pool 1. This can ensure that when the piston rod of the cylinder 42 is extended, the workpiece is separated from the immersion liquid and the reaction pool 1. In this embodiment, the number of cylinders 42 is four, with two on each side of the reaction pool 1. The bottom end of the casing of the cylinder 42 is fixedly set at the movable end of the reciprocating slide 41 and moves synchronously with the movable end of the reciprocating slide. It is particularly important to note that the length of the cross bar 2 is greater than the distance between the two transmission plates 43. This can ensure that when the transmission plate 43 rises or falls, it synchronously drives the cross bar 2 and the workpiece thereon to transfer.

[0026] The reaction pool 1 referred to in this embodiment generally includes a degreasing pool, a neutralization pool, a chemical polishing pool, an anodic oxidation pool, a surface conditioning pool and a dyeing pool. The specific number can be increased or decreased according to the process requirements. In this embodiment, only three reaction pools 1 are shown for reference.

[0027] When in use, the aluminum alloy workpiece is first clamped on the fixture 3, and then the fixture 3 is hung on the crossbar 2, and the crossbar 2 for hanging the workpiece is placed on the limit groove 11 on the first reaction pool 1, and then the device is started, the piston rod of the cylinder 42 extends, driving the transmission plate 43 to rise, and the transmission plate 43 drives the crossbar 2 to rise upward through the constraint of the limit groove 11, and then the movable end of the reciprocating slide 41 moves forward, driving the cylinder 42 and the transmission plate 43, the crossbar 2, etc. to move towards the next reaction pool 1, and after reaching the designated position, the piston rod of the cylinder 42 retracts, and the crossbar 2 is transferred to the limit groove 11 on the next reaction pool 1, and then the movable end of the reciprocating slide 41 moves backward, driving the cylinder 42 and the transmission plate 43 to return to the initial position, waiting for the next operation, so that the automatic transfer of the aluminum alloy workpiece is realized. The present device can realize the automatic transfer of the workpiece by providing a plurality of reaction pools 1 and the automatic driving mechanism 4 arranged in sequence. Compared to traditional manual transfer methods, the device can quickly and continuously move workpieces from one reaction tank 1 to the next, significantly improving work efficiency and reducing workpiece processing time. The application of this device effectively shortens production cycles and improves the overall production capacity of aluminum alloy workpiece anodizing.

[0028] like Figure 2 As shown, based on the technology of the above-mentioned mechanism, the present device further adds a frame 5 and a bridge rod 51 structure. Specifically, the frame 5 is arranged at the front end of the last reaction pool 1. The two sides of the frame 5 are inclined, and the inclined sides are consistent with the conveying direction of the cross bar 2. At the bottom ends of the inclined sides of the frame 5, a bridge rod 51 is horizontally arranged. When the cross bar 2 of the hanging fixture 3 is moved to the frame 5, the cross bar 2 will slide down along the inclined sides of the frame 5 to the bridge rod 51 and stay to dry.

[0029] like Figure 4 As shown, in order to prevent the crossbar 2 from tilting or deflecting during free sliding, annular grooves 21 are provided at both ends of the crossbar 2 to match the inclined edges of the frame 5 and the lap rods 51 .

[0030] like Figure 5 As shown, in a preferred embodiment, the crossbar 2 is provided with a plurality of hanging slots 22 for hanging the fixtures 3 along the length direction. This can increase the number of hanging fixtures and improve the processing efficiency of the workpiece.

[0031] like Figure 6 As shown, in another preferred embodiment, short rods 23 are further provided on both sides of the cross bar 2. In this embodiment, a short rod 23 is provided on each side of the cross bar 2. The short rod 23 is fixedly connected to the center position of the cross bar 2 through a connecting rod. The function of the short rod 23 is also to hang the clamp 3. It should be noted that the maximum distance between the short rods 23 should be less than the inner length of the reaction pool 1, so as to ensure that the reaction pool 1 can accommodate the short rods 23 and the cross bar 2.

[0032] In addition, if Figure 2 As shown, the device also includes a water collecting tank 6, which is arranged at the bottom of the overlapping rod 51. A filter screen 61 is provided in the water collecting tank 6. The water collecting tank 6 is used to collect chemical liquids dripping from the workpieces on the overlapping rod 51 to prevent pollution of the workshop and ensure a clean and safe working environment.

[0033] Furthermore, the device also includes a drying device, which is installed at the front end of the frame 5. The drying device can select a fan with hot air, which can dry the workpiece in real time, thereby improving operating efficiency.

[0034] like Figure 3 As shown, the reciprocating slide 41 described in the present device includes a slide rail 411, a slider 412, a power source 413 and a table 414, wherein two slide rails 411 are arranged in parallel, and the slide rails 411 are installed on the base frame 8. The base frame 8 is a double-layer frame, the upper layer is used to install the reaction pool 1, and the lower layer is used to install the slide rail 411 and the power source 413. The setting direction of the slide rail 411 is consistent with the arrangement direction of the reaction pool 1. A slider 412 is set on each slide rail 411, and a table 414 is set on the upper side of the slider 412. The table 414 is used to install the cylinder 42. The casing of the power source 413 is fixed on the lower layer of the base frame 8, and the movable end of the power source 413 is connected to the table 414 or the slider 412.

[0035] In addition, in order to ensure the stability of the lifting and lowering of the transmission plate 43, the present device also includes a plurality of guide mechanisms. In this embodiment, four guide mechanisms are provided, and two are provided at the bottom of each transmission plate 43. Taking one of the guide mechanisms as an example, it includes a guide column 44 and a slide rod 45, wherein the upper end of the slide rod 45 is fixedly mounted on the horizontal extension end of the transmission plate 43, the guide column 44 is mounted on the table 414, and a vertical through hole is provided in the center of the guide column 44. The slide rod 45 is slidably connected to the vertical through hole in the center of the guide column 44. The specific structure can be understood by referring to 1-3.

[0036] In addition, it should be noted that the electrical components in the present invention are all connected to the control center PLC, which controls the operation of each component in an integrated manner. PLC is a well-known mature technology and will not be described in detail here.

[0037] The use of this device can greatly improve the work efficiency of the anodizing process, protect the health and safety of workers, and ensure the stability of workpieces during transfer and processing. At the same time, it meets the automation needs of modern production and has broad application prospects and market value.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
