Description

Technical Field

[0001] The invention relates to the field of special-shaped copper strip production, in particular to copper strip forging equipment and method with cleaning and drying functions. Background Art

[0002] As a key substrate required by semiconductor discrete devices and new energy vehicle industries, special-shaped copper strips play an extremely important role in the field of modern information technology. Special-shaped copper strips produced by forging and rolling have the characteristics of dense grains and excellent mechanical properties, and are widely favored by the high-end market. However, limited by the current level of technology, copper strips produced by forging often have high residual stress inside. In the subsequent cooling process, they are in direct contact with cooling water, which will lead to uneven cooling rates inside and outside, resulting in reduced structural accuracy. In the subsequent stamping process, the frame may be twisted or deformed, limiting its application in the precision electronics industry.

[0003] Moreover, the existing special-shaped copper strips are often cooled and lubricated with rolling oil during production. The surface of the copper strips processed in this way will be stained with oil. Although water cooling is used in subsequent steps, due to the complex cross-sectional structure of the special-shaped copper strips, simple water cooling cannot completely remove the oil stains attached to the surface. The oil stains will cause poor bonding between the plastic packaging material and the lead frame, resulting in abnormal stratification, thereby affecting the airtightness of the integrated circuit product after plastic packaging, and further causing oxidation of the chip and the welding wire in the plastic package, which may cause the failure of the electronic product in severe cases. Summary of the invention

[0007] Preferably, the cooling and brushing assembly includes a cleaning pool, a bracket A, a conveying roller A, a polishing mechanism and a spray pipe. The bracket A is fixed to the bottom of the cleaning pool to support the cleaning pool. The bottom wall of the cleaning pool is provided with a drainage hole. Two conveying rollers A are provided, both of which are located in the cleaning pool and rotatably connected thereto. The copper belt passes through the cleaning pool and is supported by the two conveying rollers A. There are three spray pipes and three polishing mechanisms. The three spray pipes and the three polishing mechanisms are staggeredly installed on the cleaning pool. The output direction of any spray pipe is relative to the polishing mechanism and the position corresponds. The spray pipe is supplied with water by a central water pump.

[0008] Preferably, the polishing mechanism includes a motor B and a brush wheel, the motor B is fixed to the cleaning tank, the brush wheel is connected to its output end, and the brush wheel fits the surface of the copper belt.

[0009] Preferably, the pretreatment component includes a processing box, a conveying roller B, a support frame and a support frame B. The support frame B is fixed at the bottom of the processing box to support the processing box. There are multiple conveying rollers B, all of which are installed in the processing box and rotatably connected thereto. The copper belt is supported by the conveying rollers B when passing through the processing box. The support frame is fixed at the upper end of the processing box. A pressure plate is provided below the support frame. Multiple adjustment springs are installed between the top of the support frame and the pressure plate. The two ends of the adjustment springs are respectively fixed to the support frame and the pressure plate. A hard brush is fixedly installed at the bottom of the pressure plate. The adjustment spring makes the hard brush contact the upper surface of the copper belt.

[0010] Preferably, the air sleeve and the closing structure are both annular structures, and the inner diameter of the end of the air sleeve away from the closing structure is smaller than the inner diameter of the closing structure.

[0011] Preferably, a gear ring is fixed to the outer ring of the centrifugal cylinder, and a gear is fixedly installed at the output end of the motor A, and the gear is meshed with the gear ring.

[0014] A cleaning and drying method for a copper strip forging and rolling equipment with cleaning and drying functions comprises the following steps:

[0015] S1: The forging molds of the special-shaped copper strips of the production specifications are installed on three independent forging devices at angles of 14°, 16° and 18° respectively; the copper strips pass through the multi-directional forging device at a speed of 2.6-3.2m / min, and the hard brush treats the surface of the copper strips during this process;

[0016] S2: The copper strip passes through the cooling and brushing assembly, the strip running speed is 2.6m / min, and 25-degree cooling water is used to pre-cool the strip using a spray pipe. During this process, the polishing mechanism processes both sides of the copper strip, and the brush roller rotates at a speed of 1500rpm for polishing and brushing;

[0017] S3: By passing through the cooling and drying component, cooling water is sprayed into the centrifugal drum and onto the surface of the copper belt to further evenly reduce the temperature of the copper belt. When the copper belt moves out of the centrifugal drum, the air jacket mixed with nitrogen will blow air to the copper belt through the wedge-shaped groove to achieve drying, and finally reel it up.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The copper strip forging equipment and method with cleaning and drying functions are provided with a cooling brushing component. First, after the copper strip is forged, the copper strip is cooled by spraying water after cooling. Since the copper strip is not immersed in cooling water, the difference in the cooling rate inside and outside is small. In this gradual cooling process, the motor B drives the brush wheel to treat the surface of the copper strip, which can effectively remove stains, oil stains, rust, etc. Compared with the treatment after complete cooling, the treatment effect is better, the treatment process is easier, and the copper strip will not be deformed due to the large temperature difference, thereby preventing subsequent distortion and deformation during the cleaning process of the copper strip.

[0020] 2. Copper strip forging equipment and method with cleaning and drying functions. By setting a cooling and drying component, the copper strip will pass through a centrifugal cylinder after initial cooling. Cooling water is provided in the centrifugal cylinder. When rotating, the cooling water will surround the surface of the copper strip to flush and cool it. During the flushing process, the cooling is linear, and the surface stains are more easily washed away. The excess cooling water of the centrifugal cylinder will overflow from the left end. When the copper strip is about to be removed from the centrifugal cylinder, it can be flushed by high-pressure airflow, and the water droplets on its surface will be blown away and dried, which is convenient for subsequent processing, and some stress is released, and the probability of subsequent distortion is lower.

[0021] 3. The copper strip forging equipment and method with cleaning and drying functions is provided with a pretreatment component. During the forging process, the pretreatment component can promptly scrape off the forging debris to avoid the forging residues from adhering to the surface of the copper strip, which would cause pits on the surface of the copper strip during the next treatment. In addition, during the timely cleaning process, the hard brush can also play an oiling effect, and timely cleaning and oiling are convenient for subsequent cooling and flushing.

[0036] like Figure 1-9 As shown, the copper strip forging equipment with cleaning and drying functions includes a multi-directional forging device 1, and the multi-directional forging device 1 is provided with three groups. A pretreatment component 2 is provided between each adjacent multi-directional forging device 1, and also includes arranged and distributed cooling and brushing components 3 and cooling and drying components 4. After the copper strip passes through the three multi-directional forging devices 1 and the two pretreatment components 2, it passes through the cooling and brushing components 3 and the cooling and drying components 4 respectively.

[0037] The cooling and drying assembly 4 includes a water tank 401, a motor A402, a centrifugal cylinder 403, an air jacket 404 and a central water pump 405. The water tank 401 uses a water supply pipe 406 to supply water to the central water pump 405. The output end of the central water pump 405 is respectively equipped with an upper water spray pipe 407 and a lower water spray pipe 408. The centrifugal cylinder 403 is located above the water tank 401 and is rotatably connected thereto. The motor A402 is fixedly installed on the upper surface of the water tank 401 to drive the centrifugal cylinder 403 to rotate. The copper belt passes through the centrifugal cylinder 403. The upper water spray pipe 407 and the lower water spray pipe 408 leave one end of the central water pump 405 and extend into the centrifugal cylinder 403. The end of the upper water spray pipe 407 faces the inner wall of the centrifugal cylinder 403. Towards the circular inner wall of the centrifugal cylinder 403, the end of the lower water spray pipe 408 faces the upper surface of the copper belt, and both ends of the centrifugal cylinder 403 are provided with a closing structure 409. The outer circle of the closing structure 409 at the output end of the centrifugal cylinder 403 corresponding to the copper belt is provided with a circle of wedge-shaped grooves 410, and the wedge-shaped grooves 410 penetrate the closing structure 409 inwardly. The air sleeve 404 is sleeved outside the closing structure 409 and is rotatably connected to it. The air sleeve 404 and the closing structure 409 are sealed, and a cavity 411 is provided inside the air sleeve 404, and the cavity 411 is connected to the wedge-shaped groove 410. The outer circle of the air sleeve 404 is provided with an air inlet 412 connected to the cavity 411, and the air inlet 412 is connected to a high-pressure nitrogen pump.

[0038] The device also includes an unwinding device, a welding device, an inlet clamping device, a cleaning and dust removal device, a rolling device, an outlet clamping device and a winding device. The preformed special-shaped copper alloy billet is prepared by a progressive multi-directional forging method. Among them, the progressive multi-directional forging method is divided into three stages. Specifically, it includes: in the first stage, the angle of entering the die is 14°, the forging frequency is 700r / min, and the forging force is 650KN for forging to change the sliding direction of the grains so that they grow evenly in different directions. In the second stage, the angle of entering the die is 16°, the forging frequency is 750r / min, and the forging force is 700KN for further forging. In the third stage, the angle of entering the die is 18°, the forging frequency is 800r / min, and the forging force is 750KN to complete the entire forging process.

[0039] The water tank 401 is connected to the water pump and the water supply pipe 406 to pre-store cooling water. Similarly, a water receiving device is also provided on the top of the water tank 401. When the upper water spray pipe 407 and the lower water spray pipe 408 spray water into the centrifugal cylinder 403, there is a limit to the water storage in the centrifugal cylinder 403. When the maximum limit is reached, the cooling water will flow out from the copper belt inlet end of the centrifugal cylinder 403. The cooling water after flowing out can be reused after cooling. The inner wall of the centrifugal cylinder 403 will achieve the effect of water storage under the action of centrifugal force. The rotating stored water will surround the copper belt, and then flush and cool the copper belt. The hot water that first contacts the copper belt will overflow and flow out, so the copper belt can always be cooled by cooling water. The cooling effect is linear, which avoids uneven cooling and deformation of the copper belt.

[0040] The upper water spray pipe 407 mainly serves to supply water to the centrifugal cylinder 403, while the lower water spray pipe 408 mainly serves to flush and cool the copper belt. When the copper belt moves out of the centrifugal cylinder 403, high-pressure gas will be blown out from the wedge-shaped groove 410 around the copper belt, and the blown high-pressure rotating airflow will flush the water droplets on the surface of the copper belt, and the copper plate can be dried after the water droplets escape.

[0041] The cooling and brushing assembly 3 includes a cleaning pool 301, a bracket A302, a conveying roller A303, a polishing mechanism 304 and a spray pipe 305. The bracket A302 is fixed at the bottom of the cleaning pool 301 to support the cleaning pool 301. The bottom wall of the cleaning pool 301 is provided with a drainage hole 306. Two conveying rollers A303 are provided, both of which are located in the cleaning pool 301 and are rotatably connected thereto. The copper belt passes through the cleaning pool 301 and is supported by the two conveying rollers A303. There are three spray pipes 305 and three polishing mechanisms 304. The three spray pipes 305 and the three polishing mechanisms 304 are staggeredly installed on the cleaning pool 301. The output direction of any spray pipe 305 is relative to the polishing mechanism 304 and the position corresponds. The spray pipe 305 is supplied with water by a central water pump 405.

[0042] When the copper strip passes through the cleaning pool 301, the three polishing mechanisms 304 can process the surface of the copper strip. During the processing, the spray pipe 305 always sprays cooling water to the copper strip. A small amount of cooling water can not only play a preliminary cooling effect, but also cooperate with the polishing mechanism 304 to better process the surface of the copper strip. During polishing, the copper strip will not be burned, and the stains and oil stains on the surface of the copper strip are easier to remove.

[0043] The polishing mechanism 304 includes a motor B3041 and a brush wheel 3042. The motor B3041 is fixed to the cleaning pool 301, and the brush wheel 3042 is connected to the output end thereof. The brush wheel 3042 is in contact with the surface of the copper strip.

[0044] The brush wheel 3042 uses a soft metal wire brush or a hard fiber brush, which needs to meet the requirements of not damaging the surface of the copper belt and not changing the shape of the copper belt when cleaning the copper belt.

[0045] The pretreatment component 2 includes a processing box 201, a conveying roller B202, a support frame 203 and a bracket B204. The bracket B204 is fixed at the bottom of the processing box 201 to support the processing box 201. There are multiple conveying rollers B202, all of which are installed in the processing box 201 and rotatably connected thereto. When the copper belt passes through the processing box 201, it is supported by the conveying roller B202. The support frame 203 is fixed at the upper end of the processing box 201. A pressure plate 205 is provided below the support frame 203. A plurality of adjusting springs 206 are installed between the top of the support frame 203 and the pressure plate 205. The two ends of the adjusting spring 206 are respectively fixed to the support frame 203 and the pressure plate 205. A hard brush 207 is fixedly installed at the bottom of the pressure plate 205. The adjusting spring 206 makes the hard brush 207 contact with the upper surface of the copper belt.

[0046] The hard brush 207 is a metal brush, and the contact force between it and the copper belt is controlled by the adjusting spring 206. The contact force between the pressure plate 205 and the copper belt can be changed by changing the compression amount of the adjusting spring 206. When the copper belt passes through the hard brush 207, its surface will be preliminarily processed.

[0047] The air sleeve 404 and the closing structure 409 are both annular structures, and the inner diameter of the end of the air sleeve 404 away from the closing structure 409 is smaller than the inner diameter of the closing structure 409 .

[0048] When the air jacket 404 is filled with high-pressure gas, the gas inside it will be discharged around the wedge-shaped groove 410, and the wedge-shaped groove 410 is in a rotating state, so the dry gas for treating the copper belt is in a surrounding copper belt type. In this treatment process, the cooling water is in a centrifugal surrounding state, so after the water volume reaches the limit, it will be thrown out according to the inner circle of the closing structure 409, and the cooling water inside the centrifugal cylinder 403 will be thrown out from the large diameter outlet first. Since the inner circle diameter of the end of the air jacket 404 away from the closing structure 409 is smaller than the inner circle diameter of the closing structure 409, and there will be high-pressure gas in the inner circle of the air jacket 404, the cooling water can only be discharged from the closing structure 409 at the other end, so the cooling water will not wet the copper belt again.

[0049] A gear ring 413 is fixed to the outer ring of the centrifugal cylinder 403 , and a gear 414 is fixedly installed on the output end of the motor A402 , and the gear 414 meshes with the gear ring 413 .

[0050] The motor A402 drives the centrifugal cylinder 403 to rotate through the gear 414 and the gear ring 413, and the rotation speed is adjustable.

[0051] Two circular tracks 415 are provided outside the centrifugal drum 403 , two annular frames 416 are fixedly installed on the water tank 401 , a plurality of rotatable rollers 417 are installed inside the annular frames 416 , the centrifugal drum 403 passes through the two annular frames 416 , and the plurality of rollers 417 are distributed in a circle outside the circular track 415 .

[0052] The end of the cleaning tank 301 corresponding to the output of the copper strip is respectively installed with brush rollers 307 distributed up and down, and the rotation direction of the brush rollers 307 is opposite to the conveying direction of the copper strip.

[0053] The rotation speed of the brush roller 307 is 1500 rpm, which can realize the reprocessing of the copper strip.

[0054] A cleaning and drying method for a copper strip forging and rolling equipment with cleaning and drying functions comprises the following steps:

[0055] S1: The forging molds of the special-shaped copper strips of the production specifications are respectively installed on three independent forging devices at angles of 14°, 16° and 18°; the copper strips pass through the multi-directional forging device 1 at a speed of 2.6-3.2 m / min, and the hard brush 207 treats the surface of the copper strips in this process;

[0056] S2: The copper strip passes through the cooling and brushing assembly 3, the strip running speed is 2.6m / min, and 25-degree cooling water is used to pre-cool the strip using the spray pipe 305. During this process, the polishing mechanism 304 processes both sides of the copper strip, and the brush roller 307 rotates at a speed of 1500rpm for polishing and brushing;

[0057] S3: By passing through the cooling and drying component 4, cooling water is sprayed into the centrifugal drum 403 and onto the surface of the copper belt to further evenly reduce the temperature of the copper belt. When the copper belt moves out of the centrifugal drum 403, the air jacket 404 mixed with nitrogen will blow air to the copper belt through the wedge-shaped groove 410 to achieve drying, and finally roll it up.

[0058] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0059] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
