[0001] The invention relates to the field of aluminum material heat treatment, and in particular to aluminum material raw material heat treatment equipment for producing aluminum-based copper-clad plates. Background Art

[0002] Aluminum-based copper-clad laminates are aluminum plates covered with a layer of copper foil. During the production process of aluminum-based copper-clad laminates, the aluminum substrate needs to be heat-treated to improve its strength. For example, Chinese patent publication number CN218710694U discloses a uniform annealing device for aluminum plate production. The device is equipped with a clamping mechanism and a servo motor to drive the placement plate to rotate the aluminum plate, so that the aluminum plate is heated more evenly, avoiding uneven heating of aluminum plates at different positions, resulting in different degrees of annealing and affecting production. While the heating tube heats the aluminum plate, the circulating fan can more quickly form a high-temperature environment in the equipment body, better meeting production needs.

[0003] However, during the annealing heating process, the aluminum substrate will expand due to thermal expansion and contraction, causing the aluminum substrate to deform, which in turn causes the size of the aluminum substrate to change, affecting the processing quality of the aluminum substrate. During annealing cooling, outside air will enter the annealing barrel, causing excessive oxidation on the surface of the aluminum substrate, increasing the subsequent grinding load on the aluminum substrate.

[0032] It also includes a DD motor 1011, a connecting plate 1012, and a preheating plate 1013; each clamping plate Ⅰ103 and clamping plate Ⅱ104 is fixedly connected to a DD motor 1011; each output shaft of the DD motor 1011 is fixedly connected to a connecting plate 1012; each connecting plate 1012 is fixedly connected to a preheating plate 1013 made of a heat-conducting material, and the preheating plate 1013 is in contact with the inner wall of the annealing tube 3, and the preheating plate 1013 is in contact with the corresponding clamping plate Ⅰ103 and clamping plate Ⅱ104, and each preheating plate 1013 is provided with a plurality of air holes.

[0033] It also includes a hollow tube 1014; the rotating rod 101 is hollow; the rotating rod 101 is provided with a plurality of circular holes 1001, and the positions of the circular holes 1001 correspond to the two adjacent clamping plates Ⅰ103 and the clamping plates Ⅱ104; the inner side of the rotating rod 101 is rotatably connected with a hollow tube 1014, and the hollow tube 1014 is fixedly connected to the support 1; a plurality of conveying holes 1002 are provided on the lower side of the hollow tube 1014, and the conveying holes 1002 are intermittently connected with the circular holes 1001.

[0034] When in use, first connect the external pump to the hollow tube 1014, then manually take out the sealing plate 5 from the notch 21 and the feed port 31, then manually push the aluminum plate 6 to be heat treated upward through the notch 21 and the feed port 31 into between the clamping plate I 103 and the clamping plate II 104, after the aluminum plate 6 contacts the limiting rod 1010, the limiting rod 1010 is squeezed, and the spring rod III 109 is in a compressed state until the aluminum plate 6 completely enters the annealing tube 3, and the limiting rod 1010 pops out under the elastic force of the spring rod III 109, and then the limiting rod 1010 limits the lower side of the aluminum plate 6, from Figure 4 and Figure 5 At this time, the clamping plate Ⅰ103 and the clamping plate Ⅱ104 clamp the aluminum plate 6, and the two limit plates 105 limit the front and rear sides of the aluminum plate 6. Then, during annealing heating, the aluminum plate 6 is limited by the clamping plate Ⅰ103, the clamping plate Ⅱ104, the limit plate 105 and the limit rod 1010 to prevent the aluminum plate 6 from deforming during the heating process.

[0035] Next, the driving machine of the control driver 102 is started, and the output shaft of the driving machine drives the gear to rotate, and the gear drives the rotating rod 101, the clamping plate Ⅰ103, the clamping plate Ⅱ104, the limit plate 105 and the aluminum plate 6 to rotate through the gear ring until the next clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105 are aligned with the feed port 31, and then the next one to be heat-treated is manually pushed upward into the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105, and so on, until all the clamping plates Ⅰ103, the clamping plates Ⅱ104 and the limit plate 105 clamp an aluminum plate 6, and then multiple aluminum plates 6 are heat-treated at one time to improve the heat treatment efficiency, and then the electric heating rod 4 is controlled to start, so that the heat generated by the electric heating rod 4 is transferred to the annealing tube 3, so that The air in the annealing tube 3 heats the aluminum plate 6 in the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105, and the heating temperature does not exceed 200 degrees Celsius. At the same time, the driving machine of the control driver 102 is started, and the gear is driven to rotate through the output shaft of the driving machine. The gear drives the rotating rod 101 to rotate through the gear ring, and the rotating rod 101 drives the corresponding clamping plate Ⅰ103, the clamping plate Ⅱ104, the limit plate 105 and the aluminum plate 6 to rotate, thereby changing the position of the aluminum plate 6, so that all parts of the aluminum plate 6 are heated evenly. Since the clamping plates Ⅰ103 and Ⅱ104 are provided with air holes to dissipate heat for the aluminum plate 6, even if the clamping plates Ⅰ103 and Ⅱ104 wrap the aluminum plate 6, the temperature of the aluminum plate 6 will not be too high locally due to poor heat dissipation.

[0036] When the aluminum plate 6 is pushed between the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105, the aluminum plate 6 will rub against the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105, thereby causing excessive wear of the aluminum plate 6. Therefore, the electromagnet 108 is powered off at the beginning, and the clamping plate Ⅱ104 is away from the clamping plate Ⅰ103 under the elastic force of the spring rod Ⅰ106, and the two limit plates 105 are away from each other under the elastic force of their respective spring rods Ⅱ107, thereby preventing the aluminum plate 6 from being pushed between the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105. Friction occurs between the limit plates 105, causing wear of the aluminum plate 6. After the aluminum plate 6 is pushed into the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105, the electromagnet 108 is energized, and the clamping plate Ⅱ104 moves toward the side close to the clamping plate Ⅰ103 under the magnetic force of the electromagnet 108, and the spring rod Ⅰ106 is compressed, so that the clamping plate Ⅰ103 and the clamping plate Ⅱ104 clamp the left and right sides of the aluminum plate 6, and the two limit plates 105 move toward each other under the magnetic force of the electromagnet 108 and clamp the front and rear sides of the aluminum plate 6.

[0037] In order to make the aluminum plate 6 be heated better and reduce the stress caused by the temperature difference during the annealing heating process, the aluminum plate 6 needs to be preheated. Therefore, after the annealing tube 3 is heated, the DD motor 1011 is controlled to start, and the connecting plate 1012 and the preheating plate 1013 are driven to rotate by the output shaft of the DD motor 1011, so that the preheating plate 1013 contacts the inner wall of the annealing tube 3, and then after the annealing tube 3 is heated, the heat can be immediately transferred to the clamping plate Ⅰ103 and the clamping plate Ⅱ104 through the preheating plate 1013, and then the aluminum plate 6 is preheated by the clamping plate Ⅰ103 and the clamping plate Ⅱ104, so that the aluminum plate 6 gradually heats up. Initially, the clamping plate Ⅰ103 and the clamping plate Ⅱ104 do not contact the inner wall of the annealing tube 3, thereby reducing the wear between the clamping plate Ⅰ103 and the clamping plate Ⅱ104 and the inner wall of the annealing tube 3 during rotation.

[0038] After annealing and heating of a batch of aluminum plates 6 are completed, the cooling assembly is controlled to slowly cool the aluminum plates 6. After cooling is completed, the electromagnet 108 is powered off, and the clamping plate II 104 moves to the side away from the clamping plate I 103 under the elastic force of the spring rod I 106. The two limit plates 105 move away from each other under the elastic force of their respective spring rods II 107, thereby releasing the plates. Subsequently, the DD motor 1011 is controlled to start, and the output shaft of the DD motor 1011 drives the connecting plate 1012 and the preheating plate 1013 to rotate, so that the preheating plate 1013 is separated from the inner wall of the annealing tube 3 until the preheating plate 1013 and the corresponding clamping plate I 103 and the clamping plate II 104 are perpendicular, then, the driving machine of the control driver 102 is started, and the gear is driven to rotate through the output shaft of the driving machine, and the gear drives the rotating rod 101, the clamping plate I 103, the clamping plate II 104, the limit plate 105 and the aluminum plate 6 to rotate through the gear ring until the aluminum plate 6 is aligned with the notch 21 and the feed port 31, and then, the sealing plate 5 is manually pulled downward, and then, the limit rod 1010 is manually pushed to both sides through an external tool, the spring rod III 109 is compressed, and the aluminum plate 6 falls out of the clamping plate I 103 and the clamping plate II 104 under the action of its own gravity, and then the annealed aluminum plate 6 is taken out.

[0039] Since dust, impurities, oil, etc. may adhere to the surface of the aluminum plate 6 during storage and transportation, impurities and debris on the aluminum plate 6 may fall onto the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limiting plate 105 under the action of high temperature during the annealing and heating process of the aluminum plate 6. Therefore, when the next batch of aluminum plates 6 are heat-treated, it is necessary to remove the impurities remaining on the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limiting plate 105 to prevent the impurities from affecting the annealing of the next aluminum plate 6. When the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limiting plate 105 are rotated to the position aligned with the notch 21 After being aligned with the feed inlet 31, the circular hole 1001 and the conveying hole 1002 are aligned and connected. Then, the external pump is controlled to start and gas is input into the hollow tube 1014. The gas is sprayed into between the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105 through the connected circular hole 1001 and the conveying hole 1002, and then the impurities remaining on the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105 are blown downward from the circular hole 1001 and the conveying hole 1002, and then the clamping plate Ⅰ103, the clamping plate Ⅱ104 and the limit plate 105 are cleaned.

[0040] Example 2

[0041] On the basis of Example 1, Figure 3As shown, the cooling assembly includes a round tube 201, a solenoid valve 202, a circulation tube 203, a cooling tube 204 and an air pump 205; the outer tube 2 is fixedly connected to two round tubes 201, and the round tubes 201 are connected to the annealing tube 3; each round tube 201 is fixedly connected to a solenoid valve 202; all the round tubes 201 are connected to a circulation tube 203, and the circulation tube 203 is fixedly connected to the solenoid valve 202, and the circulation tube 203 is located between the outer tube 2 and the annealing tube 3; the circulation tube 203 is fixedly connected to the air pump 205; all the round tubes 201 are connected to a cooling tube 204, and the cooling tube 204 is located outside the outer tube 2.

[0042] A drying block 206 is also included; a drying block 206 is fixedly connected to the end of each circular tube 201 .

[0043] The drying block 206 is made of a high temperature resistant material, which increases the service life of the drying block 206 .

[0044] The external delivery pump is connected to the round tube 201. During the annealing process of the aluminum plate 6, the electromagnetic valve 202 is controlled to make the round tube 201 connected only to the circulation tube 203. Then, the air pump 205 is controlled to start. The air pump 205 circulates the gas in the annealing tube 3 through the circulation tube 203, thereby improving the heat uniformity in the annealing tube 3 and the heating efficiency of the aluminum plate 6. When cooling the aluminum plate 6, the external pump is controlled to start first to suck the hollow tube 1014, and the closed annealing tube 3 is sucked through the connected round hole 1001 and the delivery hole 1002 to cool the annealing tube 3. The air inside is sucked out, then, the solenoid valve 202 is controlled to make the round tube 201 connected only to the cooling tube 204, and then, the external delivery pump is controlled to start, and a protective atmosphere such as nitrogen is introduced into the annealing tube 3 through the round tube 201. The temperature of the nitrogen is reduced after heat exchange with the outside air when passing through the cooling tube 204, and the nitrogen after cooling is re-delivered into the annealing tube 3, thereby cooling the aluminum plate 6 in the annealing tube 3, accelerating the cooling efficiency of the aluminum plate 6, and at the same time, the protective atmosphere such as nitrogen prevents the aluminum plate 6 from contacting with the outside air during annealing cooling, resulting in oxidation on the surface of the aluminum plate 6.

[0045] When the high-temperature nitrogen exchanges heat with the outside air while passing through the cooling tube 204, condensed water is generated in the cooling tube 204, so that the cooled nitrogen will carry moisture when it is transported into the annealing tube 3 again through the circular tube 201. Therefore, a drying block 206 is provided on the circular tube 201, so that when the cooled nitrogen is transported into the annealing tube 3 again through the circular tube 201, the drying block 206 absorbs the moisture in the nitrogen.

[0046] Example 3

[0047] On the basis of Example 2, Figure 6As shown, it also includes an insulation ring 301, a motor 302 and a wire rope 303; the outer cylinder 2 is slidably connected to the insulation ring 301; the annealing cylinder 3 is bolted to the motor 302, and the output shaft of the motor 302 is wrapped with one end of the wire rope 303, and the other end of the wire rope 303 is passed around the inner side of the annealing cylinder 3 and fixed to the insulation ring 301.

[0048] When the aluminum plate 6 is cooled down in the annealing tube 3, since the annealing tube 3 is still in a high-temperature residual heat state at this time, the annealing tube 3 with high-temperature residual heat will continue to heat the aluminum plate 6, resulting in a low cooling efficiency of the aluminum plate 6. Therefore, the motor 302 is controlled to start, and the steel wire rope 303 is wound by rotating the output shaft of the motor 302, so that the steel wire rope 303 pulls the insulation ring 301 to move to the left, and then the insulation ring 301 covers the inner wall of the annealing tube 3 with high-temperature residual heat, thereby isolating the heat of the annealing tube 3 and improving the cooling efficiency of the aluminum plate 6.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
