Description

Technical Field

[0001] The present invention relates to the technical field of aluminum sheet oxidation treatment, and specifically, to an aluminum sheet surface oxidation treatment process and a transfer clamping member. Background Art

[0002] After the aluminum sheet is produced, in order to improve the oxidation resistance of the aluminum sheet, electroplating is used to perform oxidation treatment on the surface of the aluminum sheet, so as to form a protective film on the surface of the aluminum sheet, thereby improving the service life of the aluminum sheet. Currently, when performing oxidation treatment on the aluminum sheet, several aluminum sheets are placed on the hanger at one time, and then the aluminum sheets are subjected to oxidation treatment.

[0003] In order to ensure that both sides of each aluminum sheet can be oxidized, the aluminum sheets are set vertically. However, because the thickness of the aluminum sheet is relatively thin, when the aluminum sheet is set vertically, under the action of its own gravity, the middle part of the aluminum sheet will bend to one side, causing the whole aluminum sheet to form a crescent shape. And several aluminum sheets are placed on the hanger at one time. When several aluminum sheets bend, the side walls between adjacent aluminum sheets will come into contact with each other. Since the aluminum sheet is processed in several solutions during the oxidation treatment process, when the aluminum sheet comes out of one solution and then enters another solution, it is necessary to remove the liquid on the aluminum sheet before it can be added to another solution. And the mutually contacting aluminum sheets will store some liquid. When removing the liquid from the aluminum sheet, it will prolong the time for removing the liquid, thereby prolonging the oxidation time of the aluminum sheet and reducing the oxidation efficiency of the aluminum sheet. Summary of the Invention

[0004] The purpose of the present invention is to provide an aluminum sheet surface oxidation treatment process and a transfer clamping member to solve the problems raised in the above background art.

[0005] To achieve the above purpose, one of the purposes of the present invention is to provide an aluminum sheet surface oxidation treatment process, including the following steps:

[0006] S1. Place one end of several aluminum sheets to be processed on the positioning device. The positioning device receives the aluminum sheets, then pushes the aluminum sheets so that the aluminum sheets are placed on the storage rack, and then rotates the positioning device to position the aluminum sheets.

[0007] S2. When the positioning device positions the aluminum sheets, the positioning device separates several aluminum sheets so that there is a gap between several aluminum sheets. At the same time, when the positioning device separates the aluminum sheets, it restricts the sides of the aluminum sheets so that the middle part of the aluminum sheets does not bend.

[0008] S3. The crane lifts the storage rack and transports the storage rack to the cleaning pool. The aluminum sheets in the clear water pool are cleaned of impurities. The cleaned aluminum sheets are lifted out of the clear water pool. The aluminum sheets that are not bent this time will not block the liquid, and the liquid drops from the aluminum sheets.

[0009] S4. The cleaned aluminum sheets are continuously transported by the crane to the pickling pool, and then go through neutralization, electrolytic oxidation, and are sealed after oxidation.

[0010] A second object of the present invention is to provide a transfer clamping member for realizing the transfer of aluminum sheets in the aluminum sheet surface oxidation treatment process described above. The positioning device is arranged on the storage rack. The storage rack is used to support the positioning device. The positioning device is used to receive the aluminum sheets and assist the aluminum sheets to move on the storage rack after receiving them. After the position of the aluminum sheets is determined, the positioning device positions the aluminum sheets, separates the aluminum sheets when positioning them, and supports the middle part of the aluminum sheets after separation. The positioning device includes two upper positioning members rotatably arranged on the storage rack. An auxiliary moving member is arranged at a position close to the bottom side inside the storage rack. The auxiliary moving member is used to assist in moving the position of the aluminum sheets. Lower positioning members are arranged at both ends of the auxiliary moving member. The two lower positioning members are respectively arranged on the lower sides of the two upper positioning members. A linkage mechanism is arranged between the upper positioning member and the lower positioning member. When the upper positioning member rotates, the lower positioning member rotates together with the upper positioning member through the linkage mechanism. The upper positioning member and the lower positioning member position the aluminum sheets and separate a plurality of aluminum sheets during the positioning process. At the same time, when the upper positioning member and the lower positioning member separate a plurality of aluminum sheets, they support the middle position of the aluminum sheets.

[0011] As a further improvement of this technical solution, the storage rack includes a placement frame in the shape of a hexahedron frame structure. A hanging rod is fixed at the middle position on the upper side of the placement frame. The lifting tool lifts the placement frame by hooking the hanging rod. A plurality of side rods are symmetrically fixed on the left and right inside the placement frame. A partition board is arranged between two corresponding side rods on the left and right sides. A placement interval for placing aluminum sheets is formed between a plurality of the partition boards and between the partition boards and the placement frame. The aluminum sheets to be processed are placed in the placement interval.

[0012] As a further improvement of this technical solution, a collision prevention strip is fixedly installed on the side of the side rod away from the partition board. A plurality of collision prevention blocks are fixed on both sides of the partition board. The side of the collision prevention block away from the partition board and the side of the collision prevention strip are on the same vertical plane. When the aluminum sheets are placed in the placement interval, the collision prevention blocks and the collision prevention strip are in contact with the side walls of the aluminum sheets.

[0013] As a further improvement of the technical solution, balance rods fixed to the placement frame are arranged on both sides of the hanging rod. A connecting plate is fixedly installed on the balance rod. A supporting diagonal rod is fixed to the lower side of the connecting plate. The other end of the supporting diagonal rod is fixed to the bottom of the placement frame, and the midlines of the supporting diagonal rod and one of the side rods are in the same vertical plane.

[0014] As a further improvement of the technical solution, the upper positioning member includes a rotating rod rotatably arranged on the placement frame, and the rotating rod is also rotatably arranged on several side rods. Several positioning groups are arranged on the rotating rod, and the positions of the positioning groups correspond to the positions of the placement intervals. Each positioning group includes two connecting strips fixed to the side wall of the rotating rod. One end of the connecting strip is inclined upward when the upper positioning member is not in use. A rubber block is fixed to the upwardly inclined end of the connecting strip. When the rubber block moves downward, it positions the upper end of the aluminum thin plate in the middle of the placement interval.

[0015] As a further improvement of the technical solution, the lower positioning member includes a rotating rod rotatably arranged at the bottom of the placement frame. Several positioning and separating members are fixed to both the rotating rod and the rotating rod. The positioning and separating members are fan-shaped. The positioning and separating members are used to separate several aluminum thin plates inside the placement interval. At the same time, when the positioning and separating members rotate, the positioning and separating members push two aluminum thin plates to both sides, and further position the aluminum thin plates during the process of the positioning and separating members pushing the aluminum thin plates.

[0016] As a further improvement of the technical solution, the positioning and separating member includes several push rods with one end fixed together. A separating rod is fixed to one end of the push rod. The lengths of several push rods gradually increase from the position close to the middle of the placement frame to the position far from the middle of the placement frame. The separating rod and the extending direction of the push rod form a 90-degree angle. When the aluminum thin plates are placed in the placement interval, the separating rod separates several aluminum thin plates. When the positioning and separating member rotates towards the direction close to the aluminum thin plates, the push rods push the aluminum thin plates on both sides of the push rods to both sides.

[0017] As a further improvement of the technical solution, the auxiliary moving member includes several receiving rods. Several of the receiving rods are connected together by several connecting rods, and the connecting rods are fixed to the bottom position of the placement frame. Several receiving rods are respectively arranged in the placement interval. Several positioning and separating members on the lower positioning member are respectively arranged in the gaps between two receiving rods. A slider is slidably arranged on the receiving rod. Blocking blocks are fixed to the upper sides of both ends of the receiving rod. The blocking blocks block the slider, and several roller shafts are fixed to the upper side of the slider. One end of the aluminum thin plate is placed on the roller shafts, and then the aluminum thin plate is pushed to drive the slider to place the aluminum thin plate inside the placement frame.

[0018] As a further improvement of the technical solution, a top block is fixed on one side of one of the blocking blocks close to the other blocking block, a plug-in slot is opened on the end of the sliding block close to the top block, a card block is slidably arranged in the plug-in slot, a spring is arranged on one side of the card block to push the card block away from the sliding block, and at the same time, a flip plate is hingedly connected to the top of the plug-in slot through a torsion spring, the torsion spring drives the flip plate to be set vertically, and when the flip plate is set vertically, one end of the card block is inserted into the interior of the flip plate, and when one side of the sliding block contacts the blocking block fixed with the top block, the top block pushes the card block to release the position restriction of the flip plate on the card block.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the surface oxidation treatment process of the aluminum sheet and the transfer clamp, when one end of the aluminum sheet is placed on the extension plate, the extension plate receives the aluminum sheet, and then by pushing the aluminum sheet, the extension plate drives one end of the aluminum sheet to move, so as to facilitate the placement of the aluminum sheet on the placement frame, reduce the difficulty of placing the aluminum sheet on the placement frame, and speed up the placement of the aluminum sheet.

[0021] 2. In the surface oxidation treatment process and transfer clamp of the aluminum sheet, during the movement of the aluminum sheet, the positioning and dividing parts on the upper positioning parts and the lower positioning parts restrict the aluminum sheet so that the aluminum sheet will not tilt when moving, thereby improving the accuracy of the placement of the aluminum sheet. At the same time, after the aluminum sheet is placed, the upper positioning parts and the lower positioning parts are rotated to position the aluminum sheet, and in the process of positioning the aluminum sheet, the positioning and dividing parts push two adjacent aluminum sheets apart to prevent adjacent aluminum sheets from fitting together and blocking the retention of liquid, thereby speeding up the processing speed of the aluminum sheet.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention. Example

[0043] One of the purposes of this embodiment is to provide a surface oxidation treatment process for an aluminum sheet, comprising the following steps:

[0044] S1. Place one end of several aluminum sheets to be processed on the positioning device 2, the positioning device 2 receives the aluminum sheet, and then pushes the aluminum sheet to place it on the holding rack 1, and then rotates the positioning device 2 to position the aluminum sheet;

[0045] S2. When the positioning device 2 positions the aluminum sheet, the positioning device 2 separates the plurality of aluminum sheets so that there are gaps between the plurality of aluminum sheets. At the same time, when the positioning device 2 separates the aluminum sheets, the side edges of the aluminum sheets are restricted so that the middle portion of the aluminum sheets does not bend.

[0046] S3, the crane lifts the holding rack 1 and transports the holding rack 1 to the cleaning tank, and the aluminum sheet in the clean water tank is cleaned of impurities, and the cleaned aluminum sheet is lifted out of the clean water tank. The unbent aluminum sheet will not block the liquid, and the liquid falls from the aluminum sheet;

[0047] S4. The cleaned aluminum sheet is continuously sent to the pickling tank by a crane, and then neutralized, electrolytically oxidized, and sealed after oxidation.

[0048] The second object of the present invention is to provide a transfer clamp for transferring the aluminum sheet in the above-mentioned aluminum sheet surface oxidation treatment process, see Figures 1 - 12As shown in the figure, the positioning device 2 is arranged on the storage rack 1. The storage rack 1 is used to support the positioning device 2. The storage rack 1 includes a placement frame 11 with a hexahedron frame structure. That is, the storage rack 1 is formed by welding the heads and tails of several metal rods and belongs to the frame structure. A hanging rod 12 is fixed at the middle position on the upper side of the placement frame 11. The lifting device hooks the hanging rod 12 to lift the placement frame 11. At the same time, several side rods 16 are symmetrically fixed on the left and right inside the placement frame 11. A partition plate 17 is arranged between two corresponding side rods 16 on the left and right sides. Placement intervals for placing aluminum sheets are formed between several partition plates 17 and between the partition plates 17 and the placement frame 11. The aluminum sheets to be processed are placed in the placement intervals. By setting several placement intervals, the activity space of the aluminum sheets is restricted to prevent the aluminum sheets from having enough space to fall down when bending. When the aluminum sheets inside the placement intervals are bent, the partition plates 17, the placement frame 11, the side rods 16 and the side walls of the aluminum sheets are in contact to restrict the bending of the aluminum sheets and ensure that the aluminum sheets can be placed on the placement frame 11. At the same time, anti-collision strips 18 are fixedly installed on the side of the side rods 16 far from the partition plates 17, and several anti-collision blocks 19 are fixed on both sides of the partition plates 17. When the aluminum sheets are placed in the placement intervals, the anti-collision blocks 19 and the anti-collision strips 18 are in contact with the side walls of the aluminum sheets. The anti-collision strips 18 and the anti-collision blocks 19 are used to protect the side rods 16 and the partition plates 17, so as to avoid the friction between the aluminum sheets and the side rods 16 and the partition plates 17 and reduce the wear of the aluminum sheets. At the same time, the side of the anti-collision block 19 far from the partition plate 17 and the side of the anti-collision strip 18 are on the same vertical plane. In this way, the protrusions of the anti-collision strip 18 and the anti-collision block 19 are avoided from affecting the vertical placement of the aluminum sheets.

[0049] At the same time, when several aluminum sheets are placed on the placement frame 11, the weight of the storage rack 1 will be very heavy. If the storage rack 1 slides during use, the aluminum sheets will fall off the storage rack 1. Therefore, balance rods 13 fixed on the placement frame 11 are arranged on both sides of the hanging rod 12. There are two balance rods 13 on one side of the placement frame 11. Connecting plates 14 are fixedly installed on the balance rods 13. Support diagonal rods 15 are fixed on the lower side of the connecting plates 14. The other ends of the support diagonal rods 15 are fixed at the bottom of the placement frame 11, and the center lines of the support diagonal rods 15 and one of the side rods 16 are on the same vertical plane. The connecting plates 14 are supported by the support diagonal rods 15 to increase the lateral width of the storage rack 1. After the lateral width of the storage rack 1 is increased, the stability of the storage rack 1 will be improved to prevent the aluminum sheets from falling off the storage rack 1 due to large-angle shaking when the storage rack 1 is lifted.

[0050] The positioning device 2 is used to hold the aluminum thin plates and assist the aluminum thin plates to move on the storage rack 1 after holding. After the position of the aluminum thin plates is determined, the positioning device 2 positions the aluminum thin plates. When positioning the aluminum thin plates, the aluminum thin plates are separated so that there is space between the aluminum thin plates, facilitating the electrolyte to enter between the two aluminum thin plates. At the same time, after separation, the middle part of the aluminum thin plates is supported so that the middle position of the aluminum thin plates does not bulge to one side, thereby preventing the two aluminum thin plates from bending and contacting, and preventing the two contacting aluminum thin plates from blocking the falling liquid.

[0051] The structure of the positioning device 2 is refined as follows. The positioning device 2 includes two upper positioning members 21 rotatably arranged on the storage rack 1. The upper positioning member 21 includes a rotating rod 211 rotatably arranged on the placement frame 11. The rotating rod 211 is arranged on one side of the placement frame 11. There is a side rod 16 on this side, and the rotating rod 211 is also rotatably arranged on a plurality of side rods 16. The rotating rod 211 is arranged at a position near the top of the placement frame 11. At the same time, a plurality of positioning groups are arranged on the rotating rod 211. The positions of the positioning groups correspond to the positions of the placement intervals. Each positioning group includes two connecting strips 212 fixed on the side wall of the rotating rod 211. The connecting strips 212 are arranged on the side of the rotating rod 211 away from the middle of the placement frame 11. When the upper positioning member 21 is not in use, one end of the connecting strip 212 is inclined upward. A rubber block 213 is fixed at the upwardly inclined end of the connecting strip 212. There is an inclined surface between the two rubber blocks 213. The inclined surface guides the aluminum thin plates to move between the two rubber blocks 213. When the rubber blocks 213 move downward, the rubber blocks 213 move towards the aluminum thin plates. After the rubber blocks 213 contact the aluminum thin plates, the upper ends of the aluminum thin plates in the middle of the placement interval are positioned, so that the upper sides of the aluminum thin plates in the middle of the placement interval are clamped, thereby reducing the space of the aluminum thin plates in the placement interval and further reducing the space for the aluminum thin plates to bend.

[0052] At the same time, an auxiliary moving member 22 is arranged at a position near the bottom inside the storage rack 1. The auxiliary moving member 22 is used to assist in moving the position of the aluminum thin plates. Lower positioning members 23 are arranged at both ends of the auxiliary moving member 22. The two lower positioning members 23 are respectively arranged below the two upper positioning members 21. A linkage mechanism is arranged between the upper positioning member 21 and the lower positioning member 23. When the upper positioning member 21 rotates, the lower positioning member 23 rotates together with the upper positioning member 21 through the linkage mechanism. The upper positioning member 21 and the lower positioning member 23 position the aluminum thin plates and separate a plurality of aluminum thin plates during the positioning process. At the same time, when the upper positioning member 21 and the lower positioning member 23 separate a plurality of aluminum thin plates, they support the middle positions of the aluminum thin plates.

[0053] The lower positioning member 23 includes a rotating rod 231 rotatably arranged at the bottom of the placing frame 11. The rotating rod 231 is arranged directly below the rotating rod 211. At the same time, a number of positioning and separating members 214 are fixed on both the rotating rod 231 and the rotating rod 211. The positioning and separating members 214 are fan-shaped. The positioning and separating members 214 are used to separate a number of aluminum thin plates inside the placing area, so that each aluminum thin plate has its own placement space. At the same time, when the positioning and separating members 214 rotate, the positioning and separating members 214 push two aluminum thin plates to both sides, and further position the aluminum thin plates during the process of pushing the aluminum thin plates by the positioning and separating members 214, so as to fix the position of the aluminum thin plates in the placing area. At the same time, the positioning and separating members 214 support the middle position of the aluminum thin plates after rotation, so that the middle part of the aluminum thin plates will not contact due to bending with adjacent aluminum thin plates, ensuring that the aluminum thin plates placed on the placing frame 11 will not block the falling of the liquid. At the same time, by means of the restriction of the positioning and separating members 214 on the aluminum thin plates, the stability of the aluminum thin plates placed on the placing rack 1 is improved, avoiding the aluminum thin plates falling off the placing rack 1 when the placing rack 1 transports the aluminum thin plates.

[0054] The following further details the positioning and separating members 214. The positioning and separating members 214 include a number of lever rods fixed together at one end. The lengths of the number of lever rods gradually increase from the position close to the middle of the placing frame 11 to the position far from the middle of the placing frame 11. A separating rod is fixed at one end of the lever rod. The extending direction of the separating rod and the lever rod forms a 90-degree angle. An arc-shaped guiding surface is arranged at the connection position of the separating rod and the lever rod. When the aluminum thin plates are placed in the placing area, part of the separating rods and lever rods are arranged between two aluminum thin plates. The separating rods separate a number of aluminum thin plates, leaving a space between adjacent two aluminum thin plates. Then, when the positioning and separating members 214 rotate towards the direction close to the aluminum thin plates, all the separating rods and lever rods enter between the aluminum thin plates. During the process of the positioning and separating members 214 rotating and moving downwards, the longer lever rods on the positioning and separating members 214 move towards the middle position of the placing frame 11. At this time, the lever rods drive the separating rods to move towards the middle position of the aluminum thin plates. During the rotation of the positioning and separating members 214, the position close to the middle of the aluminum thin plates is separated by the separating rods, and the lever rods push the aluminum thin plates on both sides of the lever rods to both sides, expanding the distance between the two aluminum thin plates. At the same time, the separating rods and lever rods on both sides of the aluminum thin plates restrict the two sides of the aluminum thin plates, reducing the bending degree of the aluminum thin plates, so that the bending interval of each aluminum thin plate is restricted. By this method, the possibility of the side walls of adjacent aluminum thin plates contacting is avoided. When the placing rack 1 comes out of the solution, the liquid on the aluminum thin plates drops downward due to gravity, thus avoiding the bent and contacting aluminum thin plates blocking the leaving of the liquid.

[0055] The auxiliary moving member 22 includes a plurality of receiving rods 221. The plurality of receiving rods 221 are respectively arranged in the placing intervals. Each placing interval has the same number of receiving rods 221, and the number of receiving rods 221 corresponds to the number of aluminum thin plates to be placed. At the same time, the plurality of receiving rods 221 are connected together by a plurality of connecting rods 222, that is, the connecting rods 222 penetrate through the receiving rods 221, and their two ends are fixed to the bottom position of the placing frame 11 with screws. A plurality of positioning and separating members 214 on the lower positioning member 23 are respectively arranged in the gaps between two receiving rods 221. A slider 224 is slidably arranged on the receiving rod 221. Blocking blocks 227 are fixed to the upper sides of both ends of the receiving rod 221. The blocking blocks 227 block the slider 224 to prevent the slider 224 from falling off the receiving rod 221. A plurality of roller shafts 2241 are fixed to the upper side of the slider 224. Since the thickness of the aluminum thin plate is relatively thin, when placing the aluminum thin plate on the placing frame 11, two workers need to each lift one end and then cooperate with each other to place the aluminum thin plate on the placing frame 11. During this process, the two workers need to continuously adjust the position of the aluminum thin plate, and the operation of placing the aluminum thin plate is relatively complicated, thus increasing the difficulty of placing the aluminum thin plate. However, through the guidance of the auxiliary moving member 22 for the aluminum thin plate, the difficulty of the workers placing the aluminum thin plate is reduced. During the process, only one person needs to push the aluminum thin plate, and the other person adjusts the position of the aluminum thin plate, reducing the difficulty of placing the aluminum thin plate. The operation of placing the aluminum thin plate on the placing frame 11 is as follows:

[0056] Two workers lift the aluminum thin plate. First, place one end of the aluminum thin plate on the roller shafts 2241. To facilitate the workers to place one end of the aluminum thin plate on the roller shafts 2241, an extension plate 225 is fixed to one end of the slider 224, and one end of the extension plate 225 extends outward. When the slider 224 moves to one end of the receiving rod 221, one end of the extension plate 225 extends out from the plurality of positioning and separating members 214. After the workers place one end of the aluminum thin plate on the roller shafts 2241, one of the workers does not need to carry the aluminum thin plate, and the worker away from the storage rack 1 pushes the aluminum thin plate. At this time, the aluminum thin plate will move on the roller shafts 2241, and the worker who does not lift the aluminum thin plate adjusts one end of the aluminum thin plate placed on the roller shafts 2241 to make one end of the aluminum thin plate between two corresponding positioning and separating members 214 on the upper positioning member 21 and the lower positioning member 23. The positioning and separating members 214 limit the position of the aluminum thin plate. During the process of the worker pushing the aluminum thin plate, one end of the aluminum thin plate will move on the roller shafts 2241, causing the slider 224 to drive the aluminum thin plate to be placed inside the placing frame 11.

[0057] In order to enable the slider 224 to move together with the aluminum thin plate and enable the aluminum thin plate to move stably, a top block 226 is fixed on one side of one plug block 227 close to the other plug block 227. The position where the top block 226 is arranged is at one end of the slider 224 away from the extension plate 225. At the same time, a plug slot is formed at one end of the slider 224 close to the top block 226. A clamping block 229 is slidably arranged in the plug slot. One side of the clamping block 229 is provided with a spring 2291 that pushes the clamping block 229 away from the slider 224. At the same time, a turning plate 228 is hinged in the plug slot near the top through a torsion spring. The torsion spring drives the turning plate 228 to be vertically arranged. A socket is formed on one side of the turning plate 228 close to the axis hinged to the slider 224. When the turning plate 228 is vertically arranged, one end of the clamping block 229 is inserted into the interior of the turning plate 228, that is, one end of the clamping block 229 is inserted into the socket. At this time, the vertically arranged position of the turning plate 228 is fixed. During the continuous movement of the aluminum thin plate, one end of the aluminum thin plate contacts one side of the turning plate 228. During the process of the worker continuously pushing the aluminum thin plate, because the turning plate 228 blocks the aluminum thin plate, the slider 224 moves together with the aluminum thin plate. At this time, the slider 224 slides on the receiving rod 221. During the process of the worker pushing the aluminum thin plate, another worker adjusts one end of the aluminum thin plate inserted into the placement frame 11 so that this end can be placed between the two positioning and separating parts 214 on the other side of the placement frame 11. These two positioning and separating parts 214 correspond to the two positioning and separating parts 214 when the aluminum thin plate is just placed on the auxiliary moving part 22. When the slider 224 moves to the other end of the receiving rod 221, the top block 226 contacts one end of the clamping block 229. When one side of the slider 224 contacts the plug block 227 fixed with the top block 226, at this time, the clamping block 229 is blocked by the top block 226 and is pushed into the plug slot by the top block 226. After the clamping block 229 is pushed into the interior of the plug slot by the top block 226, the top block 226 pushes the clamping block 229 to release the position restriction of the clamping block 229 on the turning plate 228. At this time, the moving aluminum thin plate will push the turning plate 228 to rotate. (The height of the plug block 227 is restricted here. When the turning plate 228 is horizontally arranged and contacts the top of the plug block 227, the side of the turning plate 228 away from the plug block 227 is lower than the upper end of the roller shaft 2241). During the rotation of the turning plate 228, the aluminum thin plate continues to move forward. At this time, one end of the aluminum thin plate moves away from the slider 224, so that one end of the aluminum thin plate extends out of the placement frame 11. When the distances between the two ends of the aluminum thin plate and the end extending out of the placement frame 11 are the same, the worker stops pushing the aluminum thin plate.

[0058] The linkage mechanism includes two sprockets 24 and two meshing gears. One of the gears is fixed on the rotating rod 211, and the other gear and one sprocket 24 are coaxially rotatably arranged on the side wall of the placement frame 11. The other sprocket 24 is fixed at the end of the rotating rod 231. A chain 25 is sleeved between the two sprockets 24. At the same time, grip rods are fixed at both ends of the rotating rod 211. After the worker places the aluminum sheet, by rotating the grip rods, the rotating rod 211 drives the gear to rotate, so that the two sprockets 24 rotate together through the connection of the chain 25. The rotating sprocket 24 drives the rotating rod 231 to rotate together. At this time, due to the meshing of the two gears, the rotation directions of the rotating rod 211 and the rotating rod 231 are opposite. When one end of the rotating rod 211 moves downward, the rotating rod 211 and the rotating rod 231 respectively drive the positioning and dividing member 214 to move toward the position close to the center of the placement frame 11. At this time, the moving positioning and dividing member 214 supports and restricts the aluminum sheet, so that while the aluminum sheet is positioned by the upper positioning member 21, the side wall of the aluminum sheet is also restricted, separating several aluminum sheets. At the same time, the middle position of the aluminum sheet is restricted by the positioning and dividing member 214, restricting the bendable space of the aluminum sheet, avoiding the aluminum sheets from fitting together due to bending, and avoiding adjacent aluminum sheets from fitting together and blocking the flow of liquid, thus accelerating the processing speed of the aluminum sheet.
