Description

Technical Field

[0001] This application relates to the technical field of production and processing of electrical components, specifically to a terminal bending and cutting machine. Background Art

[0002] A terminal is a component for connecting a storage battery to an external conductor. In electrical engineering, a terminal mostly refers to a wiring terminal, also called a connection terminal. When processing and producing such terminals, it is necessary to bend them so that the terminals have a specific shape. And in order to store and access the terminals, it is necessary to cut the terminals into multiple groups or small pieces according to the processing requirements, and perform blanking or collection after the cutting is completed. For this purpose, a terminal bending and cutting machine is required to process the terminals.

[0003] For example, the patent with the publication number CN204012144U specifically discloses a USB terminal bending and cutting machine. By combining a cutting knife and a vertical bending block on a fixed block, the bent terminals can be cut. Its structure is simple and the integration degree is high. The transverse shaping block is driven by a guiding block to further improve the integration degree of the device and reduce the volume of the device.

[0004] In the above patent, by setting positioning columns, the device can conveniently and stably position the workpiece during bending and improve the bending quality. When blanking, after the terminals are cut, they will directly fall into the discharge chute. However, this blanking method may cause the tail of the just-bent terminal to collide with the discharge chute, which may damage the terminal, cause the tail of the terminal to deform, and affect the overall shape and dimensional accuracy of the terminal. Secondly, the collision may also generate cracks or scratches, reducing the quality and reliability of the terminal. Therefore, it is necessary to provide a terminal bending and cutting machine to solve the above problems.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0042] Embodiment 1: This embodiment specifically describes the basic structure and working principle of the terminal bending and cutting machine, specifically:

[0043] like Figures 1-5 As shown, the present application provides a terminal bending and cutting machine, including a shaping mechanism 1, which is arranged in a terminal processing plant, and the shaping mechanism 1 includes a bottom plate 11, which is fixedly installed in the processing plant, and a controller is arranged on the top of the bottom plate 11, and a support seat 121 is fixedly arranged on the top of the controller;

[0044] A feeding assembly 2 is provided on one side of the support seat 121, and the feeding assembly 2 includes a bracket 21. A terminal tray 22 is provided on one side of the bracket 21. The terminal tray 22 is used to convey the terminal strips to be processed. The terminal strips are composed of a plurality of groups of small terminals that are easy to cut in series, including a terminal piece at the front end and a connecting strip fixed at the rear end of the terminal piece, and a plurality of groups of holes are provided on the terminal piece for subsequent connection.

[0045] A driving unit for driving the terminal tray 22 to rotate is provided on the back side of the terminal tray 22, and two sets of trays 23 are fixedly installed at the bottom of the terminal tray 22, and the trays 23 are used to receive the terminals conveyed by the terminal tray 22, providing a smooth path for the transmission of the terminals, and the trays 23 extend away from one side of the terminal tray 22 to the top of the support seat 121;

[0046] Meanwhile, a feeding track 24 is provided at the top of the support base 121. A feeding groove 25 is provided on the feeding track 24, and the feeding track 24 communicates with the tray 23. The terminals are adapted to enter the feeding track 24 from the tray 23 driven by the terminal tray 22. Meanwhile, a feeding part 3 is provided on one side of the feeding track 24. The feeding part 3 includes a driving motor 31. A turntable 32 is fixedly installed on the output end of the driving motor 31. The turntable 32 is located above the feeding groove 25, and a part of the turntable 32 extends into the feeding track 24 and contacts the terminals.

[0047] Meanwhile, a plurality of protrusions matching the holes on the terminals are provided outside the turntable 32. When the feeding starts, the protrusions on the turntable 32 enter the holes on the terminals. At this time, the driving motor 31 drives the turntable 32 to rotate, so that the turntable 32 drives the terminals to move forward, preparing for the next process.

[0048] As Figures 2-5 shown, a bending assembly 4 is provided outside the feeding groove 25. The bending assembly 4 includes a lower die 41. The lower die 41 is provided on one side of the feeding track 24. A connecting frame 42 is fixedly installed on the top side of the lower die 41. A first cylinder 43 is fixedly installed on the top of the connecting frame 42. The output end of the first cylinder 43 is arranged towards the lower die 41 and a upper die 44 is fixedly installed. The upper die 44 is adapted to contact the lower die 41. When the terminals are conveyed between the upper die 44 and the lower die 41 by the feeding part 3, the first cylinder 43 drives the upper die 44 to move towards the lower die 41, so that the terminal material on the top of the lower die 41 is bent and formed.

[0049] Meanwhile, a cutting component 5 is also provided on one side of the lower die 41. The cutting component 5 is used to divide the bent terminals. The cutting component 5 includes a second cylinder 51. The output end of the second cylinder 51 is arranged upwards. A support rod 52 is installed on one side of the second cylinder 51. The top of the support rod 52 is rotatably connected with a lever 53. One end of the lever 53 is rotatably installed on the output end of the second cylinder 51. A cutting knife 54 is installed downward at the end of the lever 53 far from the second cylinder 51. The position of the cutting knife 54 matches the position of the discharging end of the lower die 41. Then the bent terminals are pushed out of the lower die 41 by the feeding part 3 and cut by the cutting knife 54. In this embodiment, the cut terminals are formed by connecting five to six groups of terminals.

[0050] Meanwhile, a connecting plate 12 is also provided outside the cutting component 5. A receiving groove 13 is fixedly installed on the top of the connecting plate 12. A slideway 14 is provided on one side of the receiving groove 13. After the terminals are cut, they will directly fall into the receiving groove 13 and move to the next process through the slideway 14.

[0051] Embodiment 2: Since the cut material may directly fall downward into the material receiving groove 13, this may cause the bent part of the connecting strip at the rear end of the terminal piece to be scratched or damaged. Therefore, improvements are made to the material cutting assembly 5. Specifically:

[0052] As Figures 4-8 shown, a material turning assembly 6 is further provided on one side of the material cutting assembly 5. The material turning assembly 6 includes a base 61, which is fixedly installed on one side of the connecting plate 12 close to the material receiving groove 13. At the same time, three sets of vertical plates 62 are vertically installed on the top of the base 61. And a rotating motor 63 is fixedly installed on one side of one set of vertical plates 62. The output end of the rotating motor 63 penetrates through the vertical plate 62 and is fixedly installed with a rotating rod 64. The rotating rod 64 is installed between the other two sets of vertical plates 62 through bearings. And a placing plate 65 is fixedly installed on the rotating rod 64. The position of the placing plate 65 is close to one side of the material cutting assembly 5. Thus, after the terminal is cut by the material cutting assembly 5, it will directly fall on the top of the placing plate 65;

[0053] At the same time, in order to accurately place the materials, a plurality of placing grooves 66 are opened on the top of the placing plate 65. The number of the placing grooves 66 can be adjusted according to production needs. And in order to enable the placing plate 65 to orderly place a plurality of materials, a material pushing part 7 is provided on one side of the connecting plate 12 close to the material turning assembly 6. The material pushing part 7 includes a slide rail 71, which is fixedly installed on the top of the connecting plate 12. And a slider 72 is slidably installed on the slide rail 71. The slider 72 is adapted to move on the slide rail 71 under the drive of an external driving device. At the same time, a pushing block 73 is fixedly installed on the top of the slider 72. A plurality of clamping blocks 74 are arranged on one side of the top of the pushing block 73 facing the placing plate 65. The size of the clamping blocks 74 is adapted to the size of the placing grooves 66, and the clamping blocks 74 and the placing grooves 66 are arranged staggeredly;

[0054] When the terminals need to be stored, first, the bent terminals will continue to move forward a certain distance under the drive of the feeding part 3. When the number of suspended terminals matches the number of the placing grooves 66, the terminals are cut off by the material cutting assembly 5. At this time, the suspended terminals will directly fall on the placing plate 65, and the terminal pieces at the front end will remain on the placing plate 65, while the connecting strips will enter the inside of the placing grooves 66. Then, the slider 72 drives the pushing block 73 to move towards the direction of the placing grooves 66, so that a plurality of clamping blocks 74 are in contact with the connecting strips and push the whole terminals towards the inside of the placing grooves 66. When the terminals are in place, the clamping blocks 74 are withdrawn, and this process is repeated continuously until the placing grooves 66 are filled;

[0055] As Figure 8As shown in the figure, in order to prevent the terminals on the top of the placement groove 66 from falling off the placement plate 65 during flipping, an adsorption assembly 9 is further provided on the placement plate 65. The adsorption assembly 9 includes two groups of air pumps 91, and the two groups of air pumps 91 are fixedly installed at the bottom of the placement plate 65. At the same time, in order to cooperate with the air pump 91, the interior of the placement plate 65 is set to be hollow, and two groups of holes are provided at the positions corresponding to the air pumps 91 at the bottom of the placement plate 65. These holes are connected to the air pumps 91 to form an adsorption system.

[0056] On the top of the placement plate 65, there are multiple groups of air extraction holes 92 corresponding to the number of terminals. The air extraction holes 92 are communicated with the interior of the placement plate 65 and are used to adsorb the terminal pieces at the front ends of the terminals. When the terminals fall onto the top of the placement plate 65 after being cut off, the air extraction holes 92 will adsorb the terminal pieces, and the adsorption force is slightly less than the thrust of the pushing part 7 to ensure that the terminals will not be restricted when being pushed by the pushing part 7.

[0057] Furthermore, when it is necessary to collect the cut terminals, first, the bent terminals will continue to move forward a certain distance under the drive of the feeding part 3, and then the terminals will be cut off by the cutting component 5. At this time, the terminals will directly fall into the placement groove 66 and be adsorbed by the air extraction holes 92, and then the terminals will be pushed to the appropriate position by the pushing part 7;

[0058] When the placement groove 66 is full of terminals, the rotating motor 63 will drive the placement plate 65 to rotate 180 degrees, so that the terminals are located on the top of the receiving groove 13. At this time, the air pump 91 is controlled to stop pumping air, and the terminals lose their fixation and will separate from the placement plate 65 under the action of gravity, and the terminal pieces at the front ends of the terminals will first contact the bottom of the receiving groove 13, effectively avoiding the situation where the connecting bars of the terminals just after bending collide with the receiving groove 13 and are damaged.

[0059] Embodiment 3: In order to enable the air pump 91 to be adaptively turned on or off according to the position of the terminals when fixing and discharging the terminals, improvements are made to the adsorption assembly 9. Specifically:

[0060] As Figures 7-8 shown in the figure, a control assembly 8 is provided on the adsorption assembly 9. The control assembly 8 includes a fixing block 81, and the fixing block 81 is detachably installed on one side of the placement plate 65. At the same time, a panel is provided inside the fixing block 81, a shielding shell is provided on the outside of the panel, and two groups of electric control switches are provided inside the panel. The electric control switches are used to control the turning on and off of the air pump 91. When the placement plate 65 is in the initial position on the side of the cutting component 5, the electric control switches are in the on state, so that the air pump 91 continuously pumps air. When the terminals are driven by the placement plate 65 to rotate 180 degrees, the electric control switches are correspondingly turned off, so that the terminals inside the placement plate 65 fall downward into the storage groove.

[0061] To facilitate the feeding of terminals by the feeding section 7, the air extraction force of the air pump 91 is relatively small. As a result, the terminals may fall off when the placement plate 65 is flipped. To solve this problem, another embodiment of controlling the adsorption component 9 is described below;

[0062] As Figures 8-10 shown, multiple groups of channels are provided on the panel, including the first channel 82. A trigger ball 87 is provided in the first channel 82, and the trigger ball 87 is adapted to roll in the first channel 82. At the same time, a first contact 83 is provided on one side of the first channel 82, and a trigger switch of the air pump 91 is provided in the first contact 83 for turning on the air pump 91. And the trigger ball 87 is located in the first contact 83 in the initial state.

[0063] At the same time, a retention groove 84 is communicatively provided on the side of the first channel 82 away from the first contact 83. The retention groove 84 is used for the trigger ball 87 to stay briefly, and a gear-up switch is provided in the retention groove 84. The gear-up switch is used to increase the air extraction gear of the air pump 91, thereby strengthening the air extraction force of the air pump 91 when the placement plate 65 rotates. At the same time, a convex block 841 is provided on the side of the retention groove 84 away from the first channel 82, and an electrically controlled baffle is rotatably installed outside the convex block 841. The electrically controlled baffle is in a closed state in the initial state and is used to limit the falling position of the trigger ball 87;

[0064] At the same time, a second channel 85 is inclined and communicatively provided on the side of the retention groove 84 away from the first channel 82. The second channel 85 is also used for the trigger ball 87 to move, and a second contact 86 is provided on the side of the second channel 85 away from the retention groove 84. A trigger switch is also provided in the second contact 86 for turning off the air pump 91.

[0065] When the trigger ball 87 is in the initial position, the air pump 91 is in the on state. At this time, the placement plate 65 is in a horizontal state, continuously receives the terminals, and adsorbs and fixes the terminals through the air extraction holes 92. When the number of terminals inside the placement plate 65 reaches the transportation standard, the placement plate 65 is driven by the rotation motor 63 to rotate towards the material receiving groove 13, thereby causing the first channel 82 to tilt. At this time, the trigger ball 87 located in the first channel 82 will slide from the first channel 82 into the retention groove 84 due to gravity and contact the gear-up switch inside the retention groove 84, thereby increasing the air extraction force of the air pump 91 and making its fixation of the terminals more firm. At the same time, due to the setting of the electrically controlled baffle outside the convex block 841, the placement plate 65 will not slide out of the retention groove 84 when rotating;

[0066] When the placement plate 65 stops after rotating 180 degrees, the electric control baffle will open. At this time, the trigger ball 87 will only break away from the temporary storage groove 84 and slide to the second contact 86 at the end of the second channel 85, and come into contact with the trigger switch, causing the air pump 91 to stop working and the air extraction hole 92 to stop adsorbing and fixing the terminal. At this time, the terminal will fall from the placement plate 65 into the material receiving groove 13;

[0067] After the terminal unloading is completed, the placement plate 65 will retreat to the initial position driven by the rotating motor 63. At this time, the trigger ball 87 located in the second contact 86 will enter the temporary storage groove 84 through the second channel 85. Since the air pump 91 is still in the closed state, even if the trigger ball 87 comes into contact with the upshift switch, the air pump 91 will not be turned on. As the angle of the placement plate 65 changes, it will re-enter the first contact 83 at the end of the first channel 82 from the temporary storage groove 84 and contact the trigger switch in the first contact 83, causing the air pump 91 to be turned on again, facilitating the subsequent adsorption and fixation of the terminal. This not only realizes the precise control of the adsorption and release of the terminal, but also greatly improves the efficiency and stability of automated production.

[0068] In summary, by adding the material turning component 6 and the adsorption component 9 and optimizing the design of the material pushing part 7, the orderly arrangement, stable adsorption and safe turning of the terminals after cutting are successfully realized, effectively improving the production efficiency and product quality.

[0069] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
