Description

Technical Field

[0001] The present invention relates to the technical field of laser treatment of metal surfaces, and particularly relates to a laser surface treatment process for metal positioning blocks of industrial customized jigs. Background Art

[0002] In industrial automation equipment, as a key component, the metal positioning block of a customized jig plays a decisive role in the overall performance of the jig. Before use, the metal positioning block often needs to be subjected to surface treatments such as laser rust removal to improve its wear resistance, corrosion resistance, and dimensional accuracy.

[0003] In the prior art, when performing surface treatment on a metal positioning block, it is usually directly placed on the surface of the workbench. After the laser scanning treatment of one side is completed, it is flipped manually or with the aid of a mechanical device, and then the treatment of the next side is carried out. Since the metal positioning blocks are mostly rectangular in shape and only one side can be processed at a time, frequent flipping operations are required during the processing, which consume a large amount of time and reduce the overall processing efficiency. Summary of the Invention

[0004] Aiming at the above-mentioned drawbacks of the prior art, the present invention provides a laser surface treatment process for metal positioning blocks of industrial customized jigs, which can effectively solve the problems in the prior art that when performing surface treatment on a metal positioning block, it is usually directly placed on the surface of the workbench. After the laser scanning treatment of one side is completed, it is flipped manually or with the aid of a mechanical device, and then the treatment of the next side is carried out. Since the metal positioning blocks are mostly rectangular in shape and there are a total of six sides, and only one side can be processed at a time, frequent flipping operations are required during the processing, which consume a large amount of time and reduce the overall processing efficiency.

There are two support frames, and the two support frames are symmetrically distributed on both sides of the conveyor belt. A chain plate is fixedly connected to the outer surface of the conveyor belt. A fixing seat is arranged on the side of the chain plate away from the conveyor belt. The fixing seat is provided with a placing part for supporting an external metal positioning block through a placing cavity opened on its upper surface;

[0014] A laser processor for rust removal treatment on the surface of the metal positioning block;

[0015] Among them, the placing part includes a support seat fixedly connected to the surface of the placing cavity. The support seat is rotatably connected to a rotating seat through a rotating rod arranged on its outer side. A fixing plate is fixedly connected to the side of the rotating seat close to the support seat. A rotating plate is rotatably connected to the side of the rotating seat close to the support seat through a rotating shaft. The rotating plate and the fixing plate are perpendicularly distributed. A driving part is arranged on the outer surface of the fixing seat.

[0016] Further, the driving part includes a rack bar slidably connected to the inner wall of the placing cavity. One end of the rotating shaft away from the support seat penetrates through the rotating seat and is fixedly connected to a gear meshing with the outer surface of the rack bar. A torsion spring connected to the inside of the rotating seat is sleeved on the outer surface of the rotating shaft. A sliding rod slidably connected to the inside of the rack bar is fixedly connected to the side surface of the inner wall of the placing cavity. A spring connected to the outer surface of the rack bar is sleeved on the outer surface of the sliding rod.

[0017] Further, one end of the rack bar away from the spring penetrates through the fixing seat, and one end of the rack bar away from the spring is designed with an inclined surface.

[0018] Further, one end of the rotating rod away from the support seat penetrates through the fixing seat and is fixedly connected to a limiting rod.

[0019] Further, a loading platform fixedly connected to the upper surface of the support frame is arranged on one side of the conveyor belt. The outer surface of the loading platform is designed with an arc surface. A limiting block fixedly connected to the upper surface of the support frame is arranged on the side of the conveyor belt away from the loading platform.

After the metal positioning block is loaded, the conveyor belt drives the fixed seat to continue to move. At this time, the inclined end of the rack bar disengages from the loading table 16. Under the action of the torsion spring and the spring, the rotating plate drives the metal positioning block to rotate simultaneously. Two of the side surfaces of the rotating plate are respectively in contact with the outer surfaces of the rotating plate and the rotating seat. At this time, two planes of the metal positioning block are perpendicular upward; the conveyor belt continues to operate. After the limiting rod fixedly connected to the rotating seat passes through the limiting block, it drives the rotating seat, the rotating plate, the fixing plate and the metal positioning block inside to rotate 45 degrees simultaneously. In this state, three of the sides of the metal positioning block are respectively in contact with the surfaces of the rotating seat, the rotating plate and the fixing plate, and the other three sides are perpendicular upward, completely exposed under the laser processor.

The placement member and the driving member can make three sides of the metal positioning block face directly upward at one time, without the need for turning over one by one as in the traditional method, greatly reducing the time of turning over operations, significantly improving the efficiency of laser treatment on the surface of the metal positioning block, and improving the overall processing efficiency. The placement member can ensure the position accuracy of the metal positioning block during transportation, enable the laser processor to accurately act on the predetermined position, improve the stability of rust removal quality, and at the same time ensure that each surface can be fully rust-removed, avoid the occurrence of rust removal dead corners, and improve the comprehensiveness and uniformity of rust removal.

[0049] Among them, in S2, the laser rust removal device includes a conveying part 1. The conveying part 1 includes a conveyor belt 111 connected to the outer surface of the support frame 11. There are two support frames 11, and the two support frames 11 are symmetrically distributed on both sides of the conveyor belt 111. A chain plate 12 is fixedly connected to the outer surface of the conveyor belt 111. A fixing seat 13 is arranged on the side of the chain plate 12 away from the conveyor belt 111. A placing member 14 for supporting an external metal positioning block is arranged in the fixing seat 13 through a placing cavity opened on its upper surface;

[0050] A laser processor 2 for rust removal treatment on the surface of the metal positioning block;

[0051] Among them, the placing member 14 includes a support seat 141 fixedly connected to the surface of the placing cavity. The support seat 141 is rotatably connected to a rotating seat 142 through a rotating rod 1411 arranged on its outer side. A fixing plate 143 is fixedly connected to the side of the rotating seat 142 close to the support seat 141. A rotating plate 145 is rotatably connected to the side of the rotating seat 142 close to the support seat 141 through a rotating shaft 144. The rotating plate 145 and the fixing plate 143 are perpendicularly distributed. A driving member 15 is arranged on the outer surface of the fixing seat 13. The rotating rod 1411 and the rotating shaft 144 are arranged on adjacent sides of the rotating seat 142, and the rotating rod 1411 and the rotating shaft 144 are perpendicularly distributed. Both the fixing plate 143 and the rotating plate 145 adopt a hollow design

[0052] The driving member 15 includes a rack bar 151 slidably connected to the inner wall of the placing cavity. One end of the rotating shaft 144 away from the support seat 141 penetrates through the rotating seat 142 and is fixedly connected to a gear 152 meshing with the outer surface of the rack bar 151. A torsion spring 153 connected to the inside of the rotating seat 142 is sleeved on the outer surface of the rotating shaft 144. A sliding rod slidably connected to the inside of the rack bar 151 is fixedly connected to the side surface of the inner wall of the placing cavity. A spring 154 connected to the outer surface of the rack bar 151 is sleeved on the outer surface of the sliding rod. One end of the spring 154 away from the rack bar 151 is connected to the side surface of the inner wall of the placing cavity.

[0053] One end of the rack bar 151 away from the spring 154 penetrates through the fixing seat 13, and the end of the rack bar 151 away from the spring 154 adopts an inclined surface design.

[0054] One end of the rotating rod 1411 away from the support seat 141 penetrates through the fixing seat 13 and is fixedly connected to a limiting rod 155.

[0055] A loading platform 16 fixedly connected to the upper surface of the support frame 11 is provided on one side of the conveyor belt 111. The outer surface of the loading platform 16 adopts an arc surface design, which can fit with the inclined end of the rack rod 151. A limit block 156 fixedly connected to the upper surface of the support frame 11 is provided on the side of the conveyor belt 111 away from the loading platform 16. The outer surface of the limit block 156 adopts an arc surface design. When the limit rod 155 follows the conveyor belt 111 to move to the position of the limit block 156, under the action of the arc surface of the limit block 156, the limit rod 155 drives the rotating seat 142 to rotate forty-five degrees.

[0056] The inner wall surface of the placement cavity is fixedly connected with an inclined surface block 131 that fits with the side surface of the rotating seat 142. The fixed seat 13 is provided with a disassembly component 17 through a through groove opened in the interior thereof.

[0057] The assembly / disassembly component 17 comprises a reciprocating rod 171 slidably connected to the interior of the through slot. An extension block 172 is fixedly connected to the middle of the reciprocating rod 171. A baffle 173 is fixedly connected to the inner wall of the through slot. The outer surface of baffle 173 is provided with an elastic plate 174 connected to the outer surface of extension block 172. Two reciprocating rods 171 are located within each through slot. These rods 171 are symmetrically distributed within the fixed seat 13. Two extension blocks 172, elastic plates 174, and baffles 173 are symmetrically distributed on either side of each reciprocating rod 171.

[0058] A limiting groove 121 is defined on the side of the chain plate 12 away from the conveyor belt 111 , and an L-shaped block 175 that fits the inner wall surface of the limiting groove 121 is fixedly connected to the side of the reciprocating rod 171 close to the chain plate 12 .

[0059] A turntable 18 is provided on one side of the conveyor belt 111 . A three-sided seat 181 is fixedly connected to the upper surface of the turntable 18 . A limiting frame 1431 is fixedly connected to the outer surface of the fixing plate 143 .

[0060] Among them, there are two laser processors 2, one is fixed above the conveyor belt 111 through the support frame 11, and is used to remove rust on three surfaces of the metal positioning block, and the other laser processor 2 is fixed above the turntable 18, and is used to remove rust on the other three surfaces of the metal positioning block.

[0061] The process of loading the metal positioning block:

[0062] In practical applications, in the conveying unit 1, the conveying device arranged at the loading table 16 gradually moves a plurality of metal positioning blocks onto the upper surface of the conveyor belt 111. The conveyor belt 111 rotates intermittently. A plurality of chain plates 12 are fixedly connected to the outer surface of the conveyor belt 111. Each chain plate 12 corresponds to a fixed seat 13 and a set of placing members 14, and is used to drive the metal positioning blocks to be processed to move below the laser processor 2. The interval between each conveyance of the conveyor belt 111 is the distance between two chain plates 12.

[0063] In the initial state, the placing members 14 located below the conveyor belt 111 are all in a contracted state. Among them, the rotating seat 142 is rotationally connected to the fixed seat 13 through a rotating rod 1411, and the rotating rod 1411 is arranged on one side inside the rotating seat 142, not in the center. When the whole placing member 14 faces downward, under the action of gravity, the lower surface of the rotating seat 142 does not fit the inner wall surface of the placing cavity in the fixed seat 13, and the side of the rotating seat 142 contacts the inclined surface block 131. Among them, the inclined angle of the inclined surface of the inclined surface block 131 is 45 degrees, which limits the maximum rotation angle of the rotating seat 142. Since the rotating plate 145 is rotationally connected to the rotating seat 142 through a rotating shaft 144, when the rotating seat 142 is inclined, the whole rotating plate 145 is also in an inclined state, and the gear 152 at the outer end of the rotating shaft 144 does not mesh with the teeth on the outer surface of the rack bar 151. Under the action of the torsion spring 153, the whole rotating plate 145 rotates around the rotating shaft 144 as the center of rotation and approaches the rotating seat 142, and the rotating plate 145 is vertically distributed with the rotating seat 142.

[0064] At this time, the included angles between the rotating plate 145, the rotating seat 142, and the fixing plate 143 are all 90 degrees, that is, the rotating plate 145 is perpendicular to the rotating seat 142, the rotating plate 145 is perpendicular to the fixing plate 143, and at the same time the rotating seat 142 is perpendicular to the fixing plate 143, making the three present a mutually perpendicular spatial position relationship. The rack bar 151 in the driving member 15 extends to the outer surface of the fixed seat 13 with its inclined surface end under the action of the spring 154. The minimum included angle between the rotating plate 145 and the rotating seat 142 is 90 degrees, and the maximum included angle is 135 degrees.

[0065] When one of the fixed seats 13 moves from below the conveyor belt 111 to above following the chain plate 12 below it, the fixed seat 13 and the whole placing member 14 gradually move upward. Under the action of its own gravity, the rotating seat 142 drives the rotating rod 1411 and the limiting rod 155 to rotate 45 degrees at the same time. The rotating seat 142 separates from the inclined surface of the inclined surface block 131, and the lower surface of the rotating seat 142 fits the inner wall surface of the placing cavity. During this process, the rotating plate 145 and the fixing plate 143 rotate synchronously with the rotating seat 142 around the axis of the rotating rod 1411. At this time, the gear 152 on the outer surface of the rotating shaft 144 meshes with the lower surface of the rack bar 151.

[0066] The loading platform 16 is in close contact with the outer surface of the fixed seat 13. When the fixed seat 13 rotates upward in accordance with the conveyor belt 111, the inclined surface of the outer end of the rack rod 151 contacts the outer surface of the loading platform 16 (the side of the loading platform 16 near the conveyor belt 111 adopts a curved angle design). The loading platform 16 is fixed, and the rack rod 151 moves with the conveyor belt 111, and the two produce relative motion. After the inclined surface of the rack rod 151 contacts the loading platform 16, it moves toward the slide bar. During the movement, the rack rod 151 drives the gear 152 meshing with it to rotate from the upper position of the loading platform 16. The rotating shaft 144 and the rotating plate 145 are fixedly connected to the gear 152. When the inclined end of the rack rod 151 is completely inside the fixed seat 13, the rack rod 151 drives the rotating plate 145 to achieve a 45-degree rotation, and the lower surface of the rotating plate 145 contacts the lower surface of the inner wall of the placement cavity. In this state, the angle between the rotating plate 145 and the rotating seat 142 is one hundred and thirty-five degrees. The spring 154 is in a compressed state under the action of the rack rod 151, and the torsion spring 153 is also in a compressed state at this time, and undergoes elastic deformation.

[0067] After the set of fixed seats 13 is transported to the loading station and stops, the station corresponds to the position of the loading platform 16. The conveying device installed at the loading platform 16 moves the first metal positioning block near the conveyor belt 111 toward the upper surface of the rotating plate 145 (the depth of the placement cavity is greater than the height of the rotating plate 145, that is, when in the loading station, the upper surface of the fixed seat 13 is higher than the height of the rotating plate 145, and the height of the loading platform 16 is not less than the high temperature of the fixed seat 13, thereby preventing the metal positioning block from getting stuck during the loading process). The loading position is on the side of the upper surface of the rotating plate 145 that is relatively far from the fixed plate 143 to avoid pauses caused by the metal positioning block colliding with the fixed plate 143 and the limit frame 1431 on its outer surface during loading.

[0068] The process of surface treating three sides of the metal positioning block:

[0069] After the feeding is completed, the metal positioning block is completely on the upper surface of the rotating plate 145. The conveyor belt 111 continues to rotate intermittently, driving the fixed seat 13 to continue moving. When the set of fixed seats 13 and the placement part 14 move away from the feeding table 16, the rack bar 151 is no longer pressed by the outer surface of the feeding table 16, and both the spring 154 and the torsion spring 153 start to recover their elastic potential energy (using a torsion spring 153 with a strong torsion force can smoothly flip the relatively light metal positioning block). Under their action, the inclined section of the rack bar 151 moves towards the outer surface of the fixed seat 13, and the meshing gear 152 also starts to rotate. The rotating shaft 144, the rotating plate 145, and the gear 152 rotate 45 degrees around the axis of the rotating shaft 144, driving the metal positioning block to rotate. At this time, two sides of the metal positioning block face directly upward. The rotating plate 145, the rotating seat 142, and the fixing plate 143 again present a mutually perpendicular spatial position relationship.

[0070] The conveyor belt 111 continues to rotate, and the lower surface of the rotating seat 142 fits with the lower surface of the inner wall of the placement cavity. In this state, the limiting rod 155 is in an inclined state until the fixed seat 13 and the placement part 14 move to the position where the limiting block 156 is located. The limiting block 156 remains stationary, and the limiting rod 155 moves along with the chain plate 12, and relative movement occurs between the two. When the limiting rod 155 passes by the limiting block 156, the outer surface of the limiting rod 155 contacts the arc-shaped edge of the limiting block 156. Under the action of the limiting block 156, the limiting rod 155 gradually changes from an inclined state to a horizontal state, rotating a total of 45 degrees. Correspondingly, the rotating rod 1411 fixedly connected to the limiting rod 155 and the rotating seat 142 also rotate 45 degrees, driving the internal metal positioning block to rotate synchronously.

[0071] After the rotation is completed, the side surface of the rotating seat 142 fits with the inclined surface of the inclined block 131. At this time, three sides of the metal positioning block face directly upward, and the other three sides are respectively in contact with the outer surfaces of the rotating seat 142, the fixing plate 143, and the rotating plate 145. The placement part 14 places the metal positioning block and keeps it in this state and continues to convey it forward.

[0072] The process of surface treatment of the metal positioning block:

[0073] The placement member 14 stabilizes the metal positioning block in a state where three sides face upward, and moves the metal positioning block towards the laser processor 2 located at the position of the conveyor belt 111. The laser processor 2 emits a laser beam towards the metal positioning block below. Under the laser irradiation, atoms or molecules on the surface of the rust layer of the metal positioning block will absorb sufficient energy, overcome the binding force with the metal substrate, and be directly peeled off from the surface. This photo-stripping effect is particularly obvious when the laser energy is high enough, and can instantly remove the rust layer from the surface of the metal positioning block. The photo-stripping effect cooperates with thermal expansion stripping and photochemical decomposition to jointly achieve an efficient rust removal effect. During the rust removal process of the laser processor 2, the laser beam will scan along the three upward-facing surfaces of the metal positioning block. Parameters such as the scanning speed and the pulse frequency of the laser are also adjusted according to the actual situation to ensure that the rust layer is removed comprehensively and evenly, while avoiding excessive damage to the metal substrate. By precisely controlling the laser parameters and the scanning path, the rust layer can be removed efficiently and quickly without damaging the substrate of the metal positioning block, restoring the smoothness and performance of the metal surface. Thereby ensuring the accuracy of the subsequent metal positioning block during processing and application, and ensuring the processing quality.

[0074] Process of surface treatment for the other three sides of the metal positioning block:

[0075] The metal positioning block that has completed the rust removal treatment on three sides continues to move along with the conveyor belt 111 until the chain plate 12 is no longer in a horizontal state but gradually tilts, causing the fixing seat 13 and the placement member 14 to face downward. During this process, the center of gravity of the metal positioning block shifts to the outer surface of the fixing plate 143. As the degree of inclination increases, only one side of the metal positioning block is in contact with the fixing plate 143, and the other two sides are no longer in contact with the outer surfaces of the rotating seat 142 and the rotating plate 145. After continuing to tilt to a certain extent, one side of the metal positioning block still remains in contact with the fixing plate 143, and the two laser-treated surfaces are in contact with the inner surface of the limiting frame 1431 and are temporarily stopped at this position by the limiting frame 1431.

[0076] After the intermittent stop, it rotates downward to the next station. As the inclination of the turntable 145 increases, the center of gravity of the metal positioning block gradually shifts to the inner wall surface of the limit frame 1431. During the movement of the conveyor belt 111, it is difficult for the narrow limit frame 1431 to continue to support the metal positioning block. Under the action of gravity, the metal positioning block drops to the three-sided seat 181 on the surface of the lower rotary table 18 (the rotary table 18 rotates intermittently following the conveyor belt 111 and arrives in advance below the position where the metal positioning block drops at this station). The three-sided seat 181 is composed of three mutually perpendicular plates. Affected by the limit frame 1431, after the metal positioning block drops, its three surfaces that have completed surface treatment come into contact with the three inner surfaces of the three-sided seat 181, and the other three surfaces that have not been treated are vertically upward and move on the surface of the rotary table 18 following the three-sided seat 181, moving downward below the laser processor 2 at the rotary table 18, and surface rust removal treatment is achieved through the laser beam. Thus, laser rust removal treatment is completed on all six surfaces of the metal positioning block.

[0077] The process of disassembling and assembling the fixed seat 13 on the surface of the chain plate 12:

[0078] During installation, align the fixed seat 13 with the chain plate 12. There are two reciprocating rods 171 inside each fixed seat 13, and the two reciprocating rods 171 are distributed on the left and right sides inside the fixed seat 13. Simultaneously squeeze the two reciprocating rods 171 with hands to make the two reciprocating rods 171 move towards each other. During this process, the distance between the extension block 172 and the baffle 173 gradually decreases, and the elastic plate 174 is squeezed and undergoes elastic deformation. Until the outer ends of the two reciprocating rods 171 are in contact, the planes of the two L-shaped blocks 175 are in contact, and keep the disassembly and assembly part 17 in the fixed seat 13 in this state. Simultaneously penetrate the two L-shaped blocks 175 into the inside of the limit groove 121. After the side of the L-shaped block 175 away from the reciprocating rod 171 fits with the inner wall surface of the limit groove 121, release the reciprocating rod 171, and the reciprocating rod 171 and the L-shaped block 175 move away from each other under the action of the elastic plate 174. The L-shaped block 175 is divided into a rectangular section and a semi-circular section, and the limit groove 121 is also divided into a rectangular section and a circular section. After the rectangular section of the L-shaped block 175 fits with the inner wall of the rectangular section inside the limit groove 121, the locking of the fixed seat 13 is completed.

[0079] When it is necessary to remove the fixed seat 13, simultaneously squeeze the two reciprocating rods 171 with both hands. After the planes of the two L-shaped blocks 175 are in contact, the outer surface of the L-shaped block 175 no longer fits with the inner wall side of the limit groove 121. After the circular section formed by the two L-shaped blocks 175 is smaller than the rectangular section in the limit groove 121, move the fixed seat 13 and the placement part 14 upward as a whole to complete the separation of the fixed seat 13 from the chain plate 12.

[0080] In summary, the laser rust removal equipment has the following advantages:

[0081] Advantage 1. When the placing member 14 moves upward and flips over through the fixed seat 13 and the conveyor belt 111, under the action of gravity, the rotating seat 142 rotates around the axis line of the rotating rod 1411, so that the lower surface of the rotating seat 142 fits with the inner wall surface of the placing cavity; during the movement of the conveyor belt 111, the rack bar 151 fits and presses against the outer surface of the loading table 16, realizing that the rotating plate 145 fits with the inner wall surface of the placing cavity. Thus, the feeding condition is met, and the metal positioning block enters the upper surface of the rotating plate 145. The height of the loading table 16 is not less than the height of the fixed seat 13, and the depth of the placing cavity is greater than the height of the rotating plate 145. At the same time, the selection of the feeding position avoids colliding with the fixing plate 143, effectively avoiding the phenomenon of the metal positioning block getting stuck during the feeding process, realizing the gradual feeding of the metal positioning block, reducing manual intervention, and improving the feeding efficiency and consistency.

[0082] Advantage 2. When the inclined end of the rack bar 151 disengages from the loading table 16, under the action of the torsion spring 153 and the spring 154, the rotating plate 145 drives the metal positioning block to rotate simultaneously. Two of the side surfaces of the rotating plate 145 respectively fit with the outer surfaces of the rotating plate 145 and the rotating seat 142. At this time, two planes of the metal positioning block are perpendicular upward; the conveyor belt 111 continues to operate. After the limiting rod 155 fixedly connected to the rotating seat 142 passes through the limiting block 156, it drives the rotating seat 142, the rotating plate 145, the fixing plate 143 and the metal positioning block inside to rotate by forty-five degrees simultaneously. In this state, three of the surfaces of the metal positioning block respectively fit with the surfaces of the rotating seat 142, the rotating plate 145, and the fixing plate 143, and the other three surfaces are perpendicular to the directly upward direction, being completely exposed below the laser processor 2. After the treatment of these three surfaces, by means of the inclination of the chain plate 12, the center of gravity transfer of the metal positioning block, and the action of the limiting frame 1431, the metal positioning block can be smoothly transferred to the three-sided seat 181, and it is ensured that the treated surface contacts the inner surface of the three-sided seat 181, and the untreated surface faces upward, preparing for the subsequent laser rust removal treatment. The placing member 14 and the driving member 15 can enable three surfaces of the metal positioning block to face directly upward at one time, without the need for one-by-one flipping treatment like the traditional method, greatly reducing the time of flipping operations, significantly improving the efficiency of laser treatment on the surface of the metal positioning block, and enabling the overall processing efficiency to be improved. The placing member 14 can ensure the position accuracy of the metal positioning block during the conveying process, enabling the laser processor 2 to accurately act on the predetermined position, improving the stability of the rust removal quality, and at the same time ensuring that each surface can be fully rust-removed, avoiding the appearance of rust removal dead corners, and improving the comprehensiveness and uniformity of rust removal.

[0083] Advantage 3. The entire processing process of the metal positioning block realizes automatic operation through the coordinated work of components such as the conveyor belt 111, the placing member 14, the driving member 15, and the rotary table 18, reducing manual intervention, lowering the labor intensity, and at the same time improving the stability and consistency of the production process.

[0084] Advantage 4: It can be applied to process rectangular metal blocks of different sizes within a certain range, with high flexibility and wide applicability. It automatically flips during the conveying process without manual intervention, improving production efficiency and enabling continuous processes such as rust removal, reducing the time and labor intensity of manual operations.

[0085] Advantage 5: Laser rust removal uses a laser beam with a high energy density to irradiate the metal surface, causing the rust layer to instantaneously absorb the laser energy and be heated, vaporized, or decomposed, thereby achieving the purpose of rust removal. In this process, the rust layer is removed in the form of tiny particles, and these tiny particles form dust that falls on the placement member 14. The rotary conveyor belt 111 can move the plurality of fixing seats 13 and placement members 14 up and down in a cycle. When the placement member 14 and the fixing seat 13 are in a downward-rotating state, it can help the dust fall off from their outer surfaces.

[0086] Advantage 6: When one of the fixing seats 13 or the placement member 14 is worn, malfunctioning, or requires regular inspection due to long-term use, the fixing seat 13 can be quickly separated from or installed on the outer surface of the chain plate 12 through the disassembly and assembly member 17, without spending a lot of time disassembling the entire conveyor belt 111 or related complex components. This greatly improves the maintenance efficiency, reduces the equipment downtime, reduces the impact on the production schedule, and effectively reduces the maintenance cost.
