Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and in particular to an automatic feeding device for a copper rod production line and a use method thereof. Background Art

[0002] In the automated production line of copper rods, the traditional process usually involves multiple links such as loading, cutting to length, chamfering, marking and storage. The traditional production line adopts a serial layout, and the copper rods need to pass through independently set cutting machines, chamfering machines and other equipment in turn. This design results in a large equipment footprint and waste of factory space. In addition, before cutting the copper rods, the existing equipment needs to measure the length and width of the copper rods through the measuring device on the feeding device because the initial lengths of each copper rod are different. The copper rods are then fed under the cutting machine through the feeding device, and the excess parts at both ends of the copper rods are cut off in turn. In addition, the width of the copper rods is usually only measured at the ends, which may cause dimensional defects in other parts of the copper rods to go undetected.

[0003] In addition, some copper rods are prone to slight bending due to residual stress during the manufacturing or storage process. If such bent copper rods are cut directly, the actual unfolded length will be greater than the straight-line measured length, causing the length of the finished product after cutting to exceed the tolerance requirements, resulting in material waste or product failure. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing automatic feeding and changing device of the copper rod production line that occupies a large area and causes waste of factory space, the present invention provides an automatic feeding and changing device of the copper rod production line and a use method thereof.

[0013] In addition, it is particularly preferred that the limiting plate is slidably connected to the fixing block, and the fixing block is provided with a fastening screw for fixing the limiting plate.

[0014] A method for using an automatic feeding device for a copper rod production line comprises the following specific steps: Step 1: placing a plurality of copper rods side by side on a first placement rack, and then a top block transfers the copper rod located at the bottom to a first limit block; Step 2: straightening the copper rods by reciprocating movement of an electric rotary wheel, and then a slider drives abutting rods to contact the surfaces of the copper rods to measure the widths of the copper rods; Step 3: fixing the two ends of the copper rods with a clamping block, and sequentially driving the clamping parts of the copper rods to directly below two cutting mechanisms, and then using the cutting mechanisms to cut off excess parts of the copper rods; Step 4: transferring the copper rods to a chamfering mechanism and a laser marking mechanism for processing in sequence with a support plate, and then storing them on a second placement rack.

[0015] Beneficial effects: The present invention realizes the coordinated control of the first electric slide rail and the second electric slide rail, and the copper rod is transferred from the first placement rack to the processing position through the cooperation of the top block and the support plate. The copper rod is processed in sequence through the cutting mechanism, the chamfering mechanism and the laser marking mechanism, and is finally stored in the second placement rack. The cutting mechanism, the chamfering mechanism and the laser marking mechanism are integrated on both sides of the rack in sequence, replacing the traditional serial production line layout, effectively saving production space, and applying alternating pressure to the bent copper rod through the reciprocating rotation of the inclined electric wheel, effectively correcting the bending caused by residual stress and avoiding the length error after cutting caused by bending; Before cutting the copper rod, there is no need to measure the length of the copper rod first. The clamping spacing of the clamping blocks can be directly adjusted by the second driving member to adapt to the different finished lengths of the copper rod. Then, the two ends of the copper rod are fixed by the clamping blocks, and the clamping parts of the copper rod are driven to the bottom of the two cutting mechanisms in sequence by the second driving member. Then, the excess part is accurately cut off by the cutting mechanism. Therefore, it is only necessary to adjust the clamping spacing of the clamping blocks without adjusting the position of the cutting mechanism to achieve fixed-length cutting. The adaptability is strong and the operation is simple. After the electric wheel straightens the copper rod, the slider drives the abutment rod to contact the surface of the copper rod. The displacement sensor on the slider is used to measure the width of the copper rod. As the electric wheel drives the copper rod to move back and forth, the width of all areas of the copper rod can be fully tested to see if it meets the specifications, so that defective products can be discovered and eliminated in time.

[0020] The straightening assembly includes a connecting plate 101, a connecting rod 102 and an electric wheel 103; the connecting plate 101 is fixedly connected to the frame 1; ten third electric slide rails 10101 are provided on the connecting plate 101; each third electric slide rail 10101 is slidably connected to two connecting rods 102; each connecting rod 102 is fixedly connected to an electric wheel 103, which is composed of a motor and a rotating wheel.

The dynamic wheel 103 is tilted, and the electric wheel 103 located on the left side of the copper rod 111 is tilted from the front lower side to the rear upper side, and the electric wheel 103 located on the right side of the copper rod 111 is opposite to it. Therefore, through the reverse tilting setting of the electric wheel 103, the tangential components of the electric wheel 103 are in opposite directions, forming a balanced force couple to enhance its clamping and locking effect on the copper rod 111, and avoid the copper rod 111 being easily rotated and slipped due to the unidirectional torque caused by the electric wheel 103 being tilted in the same direction.

When the torque sensor detects that the abutment rod 303 generates torque on the slider 302, the slider 302 stops moving.

[0024] The top block 8 , the first limiting block 1001 and the second limiting block 7001 are all made of plastic to prevent them from causing wear to the copper rod 111 .

[0025] A guide plate is provided on the frame 1 and is located at the lower side of the connecting block 202 . The cutting waste of the copper rod 111 is guided by the guide plate, so that the cutting waste is easily collected.

[0026] The working process of the automatic feeding device of the copper rod production line of the present invention is as follows: Initially, a number of copper rods 111 are placed side by side on the first placement rack 2. The copper rod 111 at the bottom is limited by the left edge of the rack 1 to prevent the copper rod 111 from sliding downward along the inclined first placement rack 2, and cutting mechanisms 222, chamfering mechanisms and laser marking mechanisms are sequentially installed on both sides of the rack 1. When the copper rod 111 needs to be processed, the first moving part 4001 on the first electric slide rail 4 is controlled to drive the second electric slide rail 5 and the parts connected thereto to move to the left until the top block 8 is located below the bottom copper rod 111, and then the second moving part 5001 on the second electric slide rail 5 is controlled to drive the connecting bar 6 to move upward, and the connecting bar 6 drives The support plate 7 and the top block 8 move upward, so that the wedge-shaped inclined surface of the top block 8 is inserted into the gap between the adjacent copper rods 111 from below, and as the top block 8 continues to move upward, the top block 8 pushes the lowest copper rod 111 upward, so that it passes over the left edge of the frame 1 and is stuck in the groove of the top block 8, so that the copper rod 111 is separated from the first placement rack 2, and then the remaining copper rods 111 adaptively slide down under the action of gravity, and the second electric slide rail 5 and the parts connected to it are driven to move to the right by controlling the first moving part 4001, and the copper rod 111 is driven to move to the right by the top block 8 until the copper rod 111 is aligned with the connecting plate 101 located on the leftmost side, and then the second moving part 5001 is controlled to drive the connecting bar 6, The support plate 7, top block 8 and copper rod 111 move downward, and the copper rod 111 is placed in the second limiting groove of the first limiting block 1001 on the far left. The copper rod 111 is cut by controlling the cutting mechanism 222 to move downward, and the excess parts at both ends of the copper rod 111 are removed to cut the copper rod 111 into a length that meets the production requirements. Then, the second moving part 5001 is controlled to drive the connecting bar 6, the support plate 7 and the top block 8 to move downward, and then the first moving part 4001 is controlled to drive the second electric slide rail 5 and the parts connected thereto to reset to the left. Repeat the above steps to make the second moving part 5001 drive the support plate 7 and the top block 8 to move upward, so that the top block 8 can move the copper rod at the bottom of the first placement rack 2. 111 is lifted up, and at the same time, the second limit block 7001 lifts up the copper rod 111 placed on the first limit block 1001, and limits the copper rod 111 through the first limit groove of the second limit block 7001, and then the first moving part 4001 drives the second electric slide rail 5 and the parts connected to it to move to the right, so that the original copper rod 111 is transferred to the second limit groove of the next first limit block 1001, and is chamfered by the chamfering mechanism, and then the above steps are repeated to transfer the original copper rod 111 to be aligned with the laser marking mechanism. After the copper rod 111 is laser marked by the laser marking mechanism, the copper rod 111 is transferred to the second placement rack 3 for storage.

[0027] It should be noted that, since some of the copper rods 111 are slightly bent due to residual stress, if they are cut directly, the length of the finished copper rod 111 will actually be longer than the required length. Therefore, before the copper rod 111 is cut by the cutting mechanism 222, the copper rod 111 is located between the electric wheels 103. By controlling the third electric slide rail 10101 on the connecting plate 101 to drive the connecting rods 102 to move closer to each other, the connecting rods 102 drive the corresponding electric wheels 103 to move closer to each other until the electric wheels 103 are moved closer to each other. 103 clamps the copper rod 111, and then controls the motor to drive the electric wheel 103 to rotate, and the electric wheel 103 drives the copper rod 111 to move back and forth. Since the electric wheel 103 is tilted, the rotating wheel with an arc-shaped concave side wall also generates torque on the copper rod 111, thereby driving the copper rod 111 to move back and forth while causing it to rotate, and then multiple electric wheels 103 alternately apply positive and negative pressure to the bent part of the copper rod 111 to gradually straighten the copper rod 111.

[0028] After the copper rod 111 is straightened by the electric rotary wheel 103, in order to ensure the stability of the cutting part of the copper rod 111, the electric rotary wheel 103 stops driving the copper rod 111 to move back and forth, and first controls the first driving member 204 to push the two sliding blocks 203 on the same connecting block 202 to approach each other, and clamps the two ends of the copper rod 111 by the clamping block 20301, and then makes the saw blade of the cutting mechanism 222 enter the gap between the clamping blocks 20301 to cut the copper rod 111. Furthermore, since the spacing between the two cutting mechanisms 222 is different from the finished length of the copper rod 111, before cutting the copper rod 111, the second driving member 205 is controlled to drive the connecting block 202 and the parts connected thereto to move toward or away from each other until the spacing between the center points of the two connecting blocks 202 is the same as the finished length of the copper rod 111, and then controls the first driving member 204 to push the sliding blocks 203 to approach each other. Nearly, the two ends of the copper rod 111 are clamped and fixed by the clamping block 20301, and then the second driving member 205 is controlled to drive the connecting block 202 and the parts connected thereto and the copper rod 111 to move to the same side, so that the center point of one of the connecting blocks 202 is aligned with the saw blade of a cutting mechanism 222, and then the cutting mechanism 222 is controlled to move downward to cut the clamped part of the copper rod 111, and then the second driving member 205 is controlled to drive the connecting block 202 and the parts connected thereto and the copper rod 111 to move to the other side, so that the center point of the other connecting block 202 is aligned with the saw blade of another cutting mechanism 222, and then the cutting mechanism 222 is moved downward to cut the clamped part of the copper rod 111, so as to cut the copper rod 111 into a length that meets the production requirements and specifications, and when cutting the copper rod 111 into finished products of different lengths, there is no need to precisely adjust the spacing between the two cutting mechanisms 222.

[0029] Furthermore, when the saw blade of the cutting mechanism 222 enters the gap between the clamping blocks 20301 to cut the copper rod 111, the external suction device is controlled to suck the internal hollow connecting block 202 through the telescopic tube 206, so as to promptly suck away the dust and debris generated during the cutting process to prevent it from polluting the surrounding environment.

[0030] It should be noted that after the copper rod 111 is straightened by the electric wheel 103, the electric wheel 103 is controlled to continue to drive the copper rod 111 to move back and forth, and at the same time, the slider 302 is controlled to drive the abutment rod 303 along the fourth electric slide rail 301 to approach the copper rod 111 until the abutment rod 303 contacts the copper rod 111, that is, the torque sensor at the connection between the abutment rod 303 and the slider 302 detects the torque and stops. At this time, the width of the copper rod 111 is measured by the displacement sensor on the slider 302, and as the electric wheel 103 drives the copper rod 111 to move back and forth, the width of all areas of the copper rod 111 is detected, so as to detect whether the copper rod 111 meets the production specifications.

[0031] According to the above workflow, we can know that the present invention has the following effects: Through the coordinated control of the first electric slide rail 4 and the second electric slide rail 5, the copper rod 111 is removed from the first placement rack 2 and transferred to the processing position through the top block 8 and the support plate 7, and then continuously processed by the cutting mechanism 222, the chamfering mechanism and the laser marking mechanism, and finally stored in the second placement rack 3. The cutting mechanism 222, the chamfering mechanism and the laser marking mechanism are integrated on both sides of the frame 1 in sequence, replacing the traditional serial production line layout, effectively saving production space, and the inclined electric turntable 103 rotates back and forth, applying alternating positive and reverse pressure to the bending part of the copper rod 111, effectively straightening the bending caused by residual stress, and avoiding the length error after cutting caused by bending.

[0032] Before cutting the copper rod 111, there is no need to measure the length of the copper rod 111 first. The clamping spacing of the clamping block 20301 can be directly adjusted through the second driving member 205 to adapt to the different finished lengths of the copper rod 111. Then, the two ends of the copper rod 111 are fixed by the clamping block 20301, and the clamping parts of the copper rod 111 are driven to the bottom of the two cutting mechanisms 222 in turn through the second driving member 205. Then, the excess part of the copper rod 111 is accurately cut off through the cutting mechanism 222. Therefore, it is only necessary to adjust the clamping spacing of the clamping block 20301, and there is no need to adjust the position of the cutting mechanism 222 to achieve fixed-length cutting. It has strong adaptability and is easy to operate.

[0033] After the electric wheel 103 straightens the copper rod 111, the slider 302 drives the abutting rod 303 to contact the surface of the copper rod 111 (the contact is determined by the torque sensor). The displacement sensor on the slider 302 is used to measure the width of the copper rod 111. As the electric wheel 103 drives the copper rod 111 to move back and forth, the width of all areas of the copper rod 111 can be fully detected to see if it meets the specifications, so that defective products can be discovered and rejected in a timely manner.

[0034] The additional technical effects of the present invention are as follows: Among them, such as Figure 3 As shown, the top block 8 , the first limit block 1001 and the second limit block 7001 are all made of plastic material to prevent the top block 8 , the first limit block 1001 and the second limit block 7001 from causing wear to the copper rod 111 .

[0035] Example 2: Based on Example 1, Figure 1-Figure 3 As shown, it also includes a fixed block 401 and a limiting plate 402; two fixed blocks 401 are fixedly connected to one side of the rack 1 close to the first placement rack 2; the two fixed blocks 401 are commonly connected to the limiting plate 402; and a plurality of limiting pieces 40201 are provided on the limiting plate 402.

[0036] The limiting plate 402 is slidably connected to the fixing block 401 , and a fastening screw is provided on the fixing block 401 to facilitate adjustment of the distance between the limiting plate 402 and the first placement rack 2 to accommodate copper rods 111 of different specifications.

[0037] A method for using an automatic feeding device for a copper rod production line, the specific steps are as follows: Step 1: Place several copper rods 111 side by side on the first placement rack 2, and then use the top block 8 to transfer the copper rod 111 located at the bottom to the first limit block 1001; Step 2: The copper rod 111 is straightened by reciprocating the electric wheel 103, and then the slider 302 drives the abutting rod 303 to contact the surface of the copper rod 111 to measure the width of the copper rod 111; Step 3: Use the clamping block 20301 to fix the two ends of the copper rod 111, and sequentially move the clamping parts of the copper rod 111 to the bottom of the two cutting mechanisms 222, and then use the cutting mechanisms 222 to cut off the excess part of the copper rod 111; Step 4: The support plate 7 transfers the copper rod 111 to the chamfering mechanism and the laser marking mechanism in sequence for processing, and then stores it on the second placement rack 3.

[0038] The workflow of the above embodiment is as follows: When the copper rod 111 is lifted and transferred by the top block 8, it is necessary to ensure that the copper rod 111 is placed side by side on the first placement rack 2 to avoid overlapping of the copper rods 111, otherwise it is easy for the top block 8 to lift multiple copper rods 111 at the same time, affecting subsequent operations. Therefore, the limit plate 402 is manually driven to slide on the fixed block 401 so that the distance between the limit plate 402 and the first placement rack 2 is the same as the width of the copper rod 111, and then the fastening screws on the fixed block 401 are tightened to fix the limit plate 402 to the fixed block 401, so that the limit plate 40201 on the limit plate 402 limits the copper rod 111, so that only one copper rod 111 can enter between the limit plate 40201 and the first placement rack 2, thereby effectively avoiding overlapping of multiple copper rods 111.
