DETAILED DESCRIPTION

[0034] The present invention will be described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] A precise splitting device for the production and processing of copper strips, such as Figure 1 and Figure 2 As shown, it includes a front box 1, a workbench 2, a collection box 3, a drawer 4, a cutter 5, a connecting rod 12, a pulling mechanism 6 and a blanking mechanism 7. The workbench 2 is fixedly connected to the upper side of the front box 1, and the rear part of the workbench 2 is connected to the connecting rod 12 by sliding. The upper part of the connecting rod 12 is connected to the cutter 5. A collecting box 3 is welded to the lower rear part of the front box 1, and a drawer 4 that can collect the cut copper plates and strips is slidably connected to the collecting box 3. A blanking mechanism 7 is provided on the workbench 2, and the blanking mechanism 7 is used to unload the cut copper plates and strips. A pulling mechanism 6 is provided on the front box 1, and the pulling mechanism 6 is used to move the copper plates and strips.

[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the pulling mechanism 6 includes a first connecting frame 61, a driving wheel 62, a motor 63, a pulley assembly 64, a first limiting rod 65, a first return spring 66 and a driven wheel 67. The rear side of the front box 1 is slidably connected to the first connecting frame 61. Four first limiting rods 65 that can guide and limit the first connecting frame 61 are welded to the rear side of the front box 1. The first connecting frame 61 is located in front of the first limiting rod 65. The first connecting frame 61 is slidably connected to the first limiting rod 65. The upper part of the first connecting frame 61 is rotatably connected to the driving wheel 62. The surface of the driving wheel 62 is concave and convex, which can increase the friction between it and the copper plate and strip, thereby improving the conveying efficiency of the copper plate and strip. The right side of the first connecting frame 61 is connected to the motor 63 by bolts. A pulley assembly 64 is connected between the output shaft of the motor 63 and the right side of the driving pulley 62. The pulley assembly 64 consists of two pulleys and a belt. A pulley is connected to the output shaft of the motor 63, and a pulley is also connected to the right side of the driving pulley 62. A belt is wound between the two pulleys. The rotation of the output shaft of the motor 63 drives the pulley assembly 64 to rotate. A first return spring 66 is connected between the lower part of the first limiting rod 65 and the first connecting frame 61. The first return spring 66 is wound on the first limiting rod 65. The first return spring 66 can make the first connecting frame 61 move and reset. The upper rear part of the front box 1 is rotatably connected to a driven pulley 67. The driven pulley 67 is located below the driving pulley 62. The driven pulley 67 can assist the copper plate belt to move.

[0038] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, the unloading mechanism 7 includes a cylinder 72, a small rounded frame 73 and a second return spring 71. The cutter 5 is slidably connected to a small rounded frame 73 that can facilitate the unloading of the cut copper plate strip. Two second return springs 71 are connected between the upper part of the small rounded frame 73 and the upper part of the cutter 5. The two second return springs 71 are symmetrically arranged on the left and right. The second return springs 71 are both wound on the small rounded frame 73. The lower side of the workbench 2 is connected to two cylinders 72 by bolts. The two cylinders 72 are symmetrically arranged on the left and right. The telescopic rods of the cylinders 72 are fixedly connected to the connecting rod 12.

[0039] When people need to cut the copper strip accurately, this device can be used to achieve it. First, people move the first connecting frame 61 upward according to the thickness of the copper strip, and the first limiting rod 65 can play a guiding and limiting role on the first connecting frame 61. At this time, the first return spring 66 is stretched, and the first connecting frame 61 moves upward to drive the driving wheel 62 to move upward. Then people pass one end of the copper strip through the driving wheel 62 and the driven wheel 67. Then people release the first connecting frame 61, and the first connecting frame 61 moves downward under the action of the first return spring 66. At this time, the driving wheel 62 and the driven wheel 67 are in close contact with the copper strip. Then people turn on the motor 63, and the output shaft of the motor 63 rotates to drive the pulley assembly 64 and the driving wheel 62 to rotate. The rotation of the driving wheel 62 can transport the copper plate to the front side, and the driven wheel 67 can rotate to assist the copper plate strip to move forward, so that the copper plate can be automatically pulled to the front side, thereby reducing people's labor. When the copper plate strip moves to the position directly below the cutter 5, people turn off the motor 63 and turn on the cylinder 72. The telescopic rod of the cylinder 72 extends downward, driving the connecting rod 12, the cutter 5 and the small fillet frame 73 to move downward. When the cutter 5 contacts the copper plate strip, the cutter 5 can accurately cut the copper plate strip, and the small fillet frame 73 contacts the copper plate strip, and then the cutter 5 continues to move downward, and the small fillet frame 73 stops moving. At this time, the second return spring 71 is compressed, and then when the copper plate strip cutting is completed The second return spring 71 is used to move the small rounded frame 73 downward relative to the cutter 5. The downward movement of the small rounded frame 73 will push the cut copper strip to the downward side for unloading. The divided copper strip will then fall into the drawer 4, and the drawer 4 can collect the divided copper strip. Then people control the telescopic rod of the cylinder 72 to shorten upward, driving the connecting rod 12 to move upward and reset. The connecting rod 12 moves upward to drive the cutter 5 and the small rounded frame 73 to move upward and reset. Then people close the cylinder 72, so that the copper strip can be accurately segmented in turn, and the segmented copper strip can be smoothly unloaded downward. Then, when the copper strip on the workbench 2 is segmented, and the copper strip is When the belt is separated from the driving wheel 62, the first connecting frame 61 moves downward and resets under the action of the first reset spring 66, driving the driving wheel 62 to move downward and reset, and then people pull the drawer 4 to the left, and then people take out the divided copper plate strip collected in the drawer 4. After taking it out, people move the drawer 4 to the right and reset it. Repeat the above operation through the cooperation of the driving wheel 62 and the driven wheel 67, so that the copper plate strip can automatically move to the front side, thereby reducing people's labor. At the same time, the cutter 5 automatically moves downward to accurately split the copper plate strip, and the small rounded frame 73 can push the split copper plate strip downward, which can facilitate the unloading of the split copper plate strip, thereby improving the unloading efficiency of the copper plate strip.

[0040] Example 2

[0041] On the basis of Example 1, Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, it also includes a secondary pressing mechanism 8 for pressing the position around the cutting part of the copper plate strip. The secondary pressing mechanism 8 includes a connecting block 81, a sliding plate 82 and a third return spring 83. Three connecting blocks 81 are welded on the front and rear sides of the cutter 5. The three connecting blocks 81 on the front side are slidably connected with a sliding plate 82. The three connecting blocks 81 on the rear side are also slidably connected with a sliding plate 82 that can press the position around the cutting part of the copper plate strip. The third return spring 83 is connected between the lower part of the sliding plate 82 and the lower sides of the connecting blocks 81 on the left and right sides. The third return spring 83 is wound on the sliding plate 82, and the third return spring 83 can make the sliding plate 82 move and reset.

[0042] Since the copper strip is a copper plate, when it is precisely cut, the cutter 5 may cause the position around the cut part to be recessed, which makes it inconvenient for people to handle the remaining copper strip later. In order to prevent the position around the cut part of the copper strip from being deformed, it is necessary to press it. First, when the cutter 5 moves downward, the cutter 5 moves downward to drive the connecting block 81 and the sliding plate 82 to move downward. When the cutter 5 continues to move downward to cut the copper strip, the sliding plate 82 contacts the copper strip and does not move downward. Then the sliding plate 82 moves upward relative to the cutter 5. At this time, the third return spring 83 is compressed, and the sliding plate 82 The position around the split portion of the copper strip can be pressed, thereby preventing the position around the split portion of the copper strip from being deformed. Then, when the splitting of the copper strip is completed and the cutter 5 moves upward to reset, the cutter 5 moves upward to drive the connecting block 81 and the sliding plate 82 to move upward. Then, when the sliding plate 82 is separated from the copper strip, the sliding plate 82 moves downward relative to the cutter 5 under the action of the third reset spring 83, and then the sliding plate 82 and the cutter 5 are reset. Repeating the above operation can suppress the position around the split portion of the copper strip through the sliding plate 82, thereby preventing the position around the split portion of the copper strip from being deformed.

[0043] like Figure 1 、 Figure 2 、 Figure 10 、 Figure 11 and Figure 12As shown, it also includes a connecting mechanism 9 that enables the first connecting frame 61 to move automatically. The connecting mechanism 9 includes a connecting plate 91, a rotating hole plate 92, a connecting fine plate 93, a second limiting rod 94 and a connecting arc rod 95. The left and right sides of the rear of the workbench 2 are fixedly connected to the connecting plates 91. The rotating hole plates 92 are rotatably connected to the connecting plates 91. The rear of the rotating hole plates 92 are rotatably and slidably connected to the left and right sides of the first connecting frame 61. The left and right sides of the upper part of the connecting rod 12 are connected to the connecting fine plates 93. The connecting fine plates 93 are connected to the rotating hole plates 92. The upper part is connected in a rotating and sliding manner, and two second limit rods 94 are connected on both sides of the workbench 2. The two second limit rods 94 on the left are symmetrically arranged front to back, and the two second limit rods 94 on the right are also symmetrically arranged front to back. A connecting arc rod 95 is slidably connected between the two second limit rods 94 on the left, and a connecting arc rod 95 is also slidably connected between the two second limit rods 94 on the right. The second limit rods 94 can play a guiding and limiting role for the connecting arc rods 95, and the connecting arc rods 95 are all rotatably and slidably connected to the rear side of the rotating orifice plate 92.

[0044] When people need to accurately split the copper strip, first, when the cutter 5 and the connecting rod 12 move downward, the connecting rod 12 moves downward to drive the connecting thin plate 93 to move downward, and the connecting thin plate 93 moves downward to make the rotating hole plate 92 rotate. The rotating hole plate 92 rotates to make the first connecting frame 61 and the connecting arc rod 95 move upward, and the second limiting rod 94 can play a guiding and limiting role on the connecting arc rod 95. The first connecting frame 61 moves upward to stop the copper strip from being transported to the front side, and then the copper strip can be split. When the copper strip is split, and when the cutter 5 and the connecting rod 12 move upward to reset, The connecting rod 12 moves upward, driving the connecting thin plate 93 to move upward. The upward movement of the connecting thin plate 93 causes the rotating hole plate 92 to reverse. The reversal of the rotating hole plate 92 causes the first connecting frame 61 and the connecting arc rod 95 to move downward and reset, and then the copper strip can continue to be transported to the front side. In this way, during the copper strip segmentation process, the copper strip will not continue to be transported to the front side. Repeat the above operation to rotate the rotating hole plate 92, so that during the copper strip segmentation process, the copper strip will not continue to be transported to the front side, and people do not need to turn the motor 63 on and off many times, thereby improving the copper strip segmentation efficiency.

[0045] like Figure 1 、 Figure 2 、 Figure 13 and Figure 14As shown, it also includes a limit mechanism 10 for limiting the copper plate and strip, and the limit mechanism 10 includes a sliding frame 101, a limit frame 102 and a fourth return spring 103. The limit frames 102 are welded on the front and back sides of the bottom wall of the workbench 2, and the limit frames 102 are slidably connected to the sliding frames 101 that can limit the copper plate and strip. The sliding frame 101 passes through the workbench 2, and the sliding frame 101 is slidably connected to the workbench 2. The limit frame 102 can play a guiding and limiting role for the sliding frame 101. Two fourth return springs 103 are connected between the lower part of the sliding frame 101 and the bottom wall of the workbench 2. The two fourth return springs 103 are symmetrically arranged on the left and right. The fourth return springs 103 are all wound on the limit frame 102, and the fourth return spring 103 can make the sliding frame 101 move and reset.

[0046] When people need to limit the copper strip, first, when the copper strip moves to the position of the sliding rack 101, if the copper strip is thicker, the sliding rack 101 will move upward, and the limiting rack 102 can guide and limit the sliding rack 101. At this time, the fourth return spring 103 is compressed, and the sliding rack 101 can limit the copper strip, thereby preventing the copper strip from shifting. Subsequently, when the copper strip is separated from the sliding rack 101, the sliding rack 101 moves downward and resets under the action of the fourth return spring 103. Repeating the above operation can limit the copper strip through the sliding rack 101, thereby preventing the copper strip from shifting during precise segmentation.

[0047] like Figure 1 、 Figure 2 、 Figure 15 and Figure 16 As shown, it also includes an anti-warping mechanism 11 for pressing the front side of the copper plate strip, thereby preventing the front side of the copper plate strip from warping. The anti-warping mechanism 11 includes a second connecting frame 111, a large rounded frame 112 and a fifth return spring 113. The left and right sides of the front of the workbench 2 are slidably connected to the second connecting frame 111, and the second connecting frame 111 is connected to the front of the connecting arc rod 95. The upper part of the second connecting frame 111 is slidably connected with a large rounded frame 112 that can press the front of the copper plate strip, thereby preventing the front of the copper plate strip from warping. The left and right sides of the large rounded frame 112 are connected to the second connecting frame 111. The fifth return spring 113 is wound on the large rounded frame 112, and the fifth return spring 113 can move and reset the large rounded frame 112.

[0048] When people need to accurately split the copper strip, first, when the connecting arc rod 95 moves upward, the connecting arc rod 95 moves upward, driving the second connecting frame 111 and the large rounded corner frame 112 to move upward, and then the copper strip can be accurately split. When the copper strip is split, and when the connecting arc rod 95 moves downward to reset, the connecting arc rod 95 moves downward, driving the second connecting frame 111 and the large rounded corner frame 112 to move downward, the large rounded corner frame 112 contacts the copper strip, and then the second connecting frame 111 continues to move downward, which will cause the large rounded corner frame 112 to move upward relative to the second connecting frame 111. At this time, the fifth reset spring 113 is compressed, and the large rounded corner frame 112 can press the copper strip, thereby preventing the copper strip from warping during transportation. Repeating the above operation can press the front of the copper strip, thereby preventing the copper strip from warping during transportation.
