Description

Technical Field

[0001] The invention relates to the technical field of cable terminal crimping, and in particular to a portable cable crimping connection terminal device. Background Art

[0002] Cable terminal crimping machines are mainly used to crimp the ends of wires and cables to the corresponding terminals to ensure stable transmission of electrical signals. This type of equipment is widely used in industrial automation, automotive electronics, household appliances and other fields.

[0003] After searching, the Chinese patent with publication number CN104836095A discloses an automatic continuous terminal machine, including a machine platform, and a wire conveying mechanism, a wire end cutting mechanism, a wire end stripping mechanism, a stamping mechanism and a terminal conveying mechanism arranged on the machine platform. The wire conveying mechanism conveys the wires in strips, so that the wires pass through the wire end cutting mechanism, the wire end stripping mechanism and the stamping mechanism in sequence. The wire end cutting mechanism is used to cut off the end of the wire to be stamped to meet the preset processing length. The wire end stripping mechanism removes the cortex of the wire end to be stamped to expose the metal wire. The terminal conveying mechanism conveys the terminals on the terminal strip to the stamping mechanism one by one, and the stamping mechanism stamps the metal wire exposed at the wire end to be stamped with the terminal. The automatic continuous terminal machine proposed in the above scheme has a high degree of automation, and the terminal is convenient to connect with the wire end, which greatly improves the production efficiency. However, the above scheme still has the following shortcomings when it is actually used:

[0004] The terminal crimping machine proposed in the above scheme does not have the function of automatic wire feeding. When crimping multiple cables from the same batch, the staff needs to insert the cable ends into the crimping machine one by one. Inserting the cable ends one by one will consume a lot of time and manpower, especially when processing large quantities of cables. This manual operation will significantly reduce the overall production efficiency. The automated wire feeding system can greatly reduce the number and time of manual operations, thereby improving the efficiency of the crimping operation. In addition, manual insertion of the cable ends requires the staff to have high operating skills and patience to avoid operating errors. Performing this repetitive manual operation for a long time will easily make the staff feel tired, thereby increasing the risk of operating errors.

[0005] Therefore, it is necessary to design a portable cable crimping terminal device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1-11A portable cable crimping terminal device comprises a terminal crimping machine 1, a wire feeding unit, an adjustment unit and a control unit. A linear drive module 2 is installed on the side of the terminal crimping machine 1, and a linear slide 3 is assembled on the linear drive module 2. A cylinder bracket 4 is also fixed on the side of the terminal crimping machine 1, and a push cylinder 5 is installed on the cylinder bracket 4. The push cylinder 5 is arranged opposite to the cable insertion port on the terminal crimping machine 1.

[0039] The wire feeding unit includes a cable placement structure, a cable pushing structure and a transmission structure. The cable placement structure is composed of a wire feeding plate 61 and a plurality of wire feeding parts. The plurality of wire feeding parts are arranged on the wire feeding plate 61. The plurality of wire feeding parts are distributed in a linear array along the length direction of the wire feeding plate 61. The wire feeding plate 61 is connected to the linear slide 3 by a connecting rod. The wire feeding part includes a groove 62, a sliding sleeve 63, a sliding mouth 64, a connecting plate 65 and a limiting sleeve plate 66. The groove 62 is opened on the top surface of the wire feeding plate 61. The sliding sleeve 63 is slidably arranged in the groove 62. The sliding sleeve The cross-section of 63 is a semi-annular structure, and the outer surface of the sliding sleeve 63 and the inner surface of the groove 62 are fitted with each other. The sliding opening 64 is opened on the bottom surface of the wire feeding plate 61, and the sliding opening 64 and the groove 62 are connected. The connecting plate 65 is slidably arranged in the sliding opening 64, and the top end of the connecting plate 65 is fixedly connected to the sliding sleeve 63. The limiting sleeve 66 is fixedly sleeved on the connecting plate 65. The limiting sleeve 66 is located below the wire feeding plate 61, and the top surface of the limiting sleeve 66 is in contact with the bottom surface of the wire feeding plate 61. The limiting sleeve 66 is made of rubber material. When the cable at the end position moves to the position opposite to the cable insertion port on the terminal crimping machine 1, the linear drive module 2 stops running, and the linear slide 3 and the wire feeding plate 61 also stop moving. At this time, the push cylinder 5 starts running and pushes the opposite connecting plate 65 to move. When the connecting plate 65 moves, it can drive the sliding sleeve 63 to move, and the cable located on the sliding sleeve 63 will also move accordingly, which enables the end of the cable to be inserted into the cable insertion port on the terminal crimping machine 1. When the end position of the cable completes the insertion action, the terminal crimping machine 1 automatically crimps the cable.

[0040] The cable pushing structure includes a wire pushing plate 75, which is arranged above the wire feeding plate 61. The cable pushing structure also includes two fixed frames 71, a reciprocating screw rod 72, a guide rod 73 and a movable plate 74. The two fixed frames 71 are respectively fixed at both ends of the wire feeding plate 61, the reciprocating screw rod 72 is rotatably installed between the two fixed frames 71, the guide rod 73 is fixed between the two fixed frames 71, the movable plate 74 is fixed on the top surface of the wire pushing plate 75, the movable plate 74 is threadedly sleeved on the reciprocating screw rod 72, and the movable plate 74 is slidably sleeved on the guide rod 73, and a plurality of slots 76 are provided on the bottom surface of the wire pushing plate 75, and a rollable roller 77 is provided in each slot 76, and each roller 77 is arranged along the length direction of the wire pushing plate 75. During the reciprocating movement of the wire pushing plate 75, the several rollers 77 thereon can push the cables between the wire feeding plate 61 and the wire pushing plate 75 to move. When the cables move to a position facing the sliding sleeve 63, the cables will fall into the sliding sleeve 63. In summary, during the reciprocating movement of the wire pushing plate 75, several cables can fall into several sliding sleeves 63 respectively under the movement of the wire pushing plate 75, thereby realizing automatic arrangement of the cables.

[0041] The transmission structure is arranged on one side of the wire feeding plate 61, and the transmission structure is used to drive the wire pushing plate 75 to reciprocate. The transmission structure includes a mounting frame 81, a rotating shaft 82, a transmission shaft 83, two bevel gears 84 and a first gear 85. The mounting frame 81 is fixed at one end of the wire feeding plate 61, and the rotating shaft 82 is rotatably mounted on the mounting frame 81 through a bearing seat. One end of the rotating shaft 82 is fixedly connected to the reciprocating screw rod 72, and the rotating shaft 82 and the reciprocating screw rod 72 are coaxially arranged. The transmission shaft 83 passes through the mounting frame 81 and is rotatably connected to the mounting frame 81. One of the bevel gears 84 is fixedly sleeved on the rotating shaft 82, and the other bevel gear 84 is fixedly sleeved on the transmission shaft 83. The two bevel gears 84 are meshed with each other, and the first gear 85 is fixedly sleeved on the end of the transmission shaft 83 away from the mounting frame 81. In the initial stage of the movement of the wire feeding plate 61, the first gear 85 will move to a position meshing with the fixed rack 112, and rotate under the action of the fixed rack 112. When the first gear 85 rotates, it will drive the transmission shaft 83 to rotate. When the transmission shaft 83 rotates, it drives the rotating shaft 82 to rotate through two mutually meshing bevel gears 84. When the rotating shaft 82 rotates, it can drive the reciprocating screw 72 to rotate. Under the limiting action of the guide rod 73, the movable plate 74 cannot rotate with the reciprocating screw 72, but will reciprocate under the rotation of the reciprocating screw 72, which makes the wire pushing plate 75 move back and forth accordingly.

[0042] The adjustment unit includes a pushing structure and a driving structure, both of which are arranged on the wire pushing plate 75. The pushing structure includes two movable active pushing plates 93, and the two active pushing plates 93 are respectively located at the front and rear ends of the wire feeding plate 61. The pushing structure also includes an assembly frame 91, four elastic connecting parts 92, a wire outlet 94 and a magnetic baffle 95. The fixed frame 71 is fixed on the top surface of the wire pushing plate 75, and the fixed frame 71 is a U-shaped structure. Each active pushing plate 93 is connected to the wire pushing plate 75 through two elastic connecting parts 92. The elastic connecting member 92 includes an outer cylinder, an inner rod and a spring. The outer cylinder is fixed on the side of the push plate 75, and the inner rod is movably inserted in the outer cylinder. One end of the inner rod extends to the outside of the outer cylinder and is fixedly connected to the movable push plate 93. The spring is arranged between the outer cylinder and the inner rod. The wire outlet 94 is opened on the movable push plate 93 close to the terminal crimping machine 1, and the wire outlet 94 is arranged opposite to a plurality of grooves 62. The magnetic baffle 95 is slidably assembled on the side of the movable push plate 93 close to the terminal crimping machine 1, and the magnetic baffle 95 is arranged opposite to the wire outlet 94. The magnetic baffle 95 is made of magnetic material.

[0043] The driving structure includes an axle 101, a winding wheel 102, two pull wires 103, a second gear 104, a movable rack 105 and a push rod 106. The axle 101 is rotatably installed on the top surface of the assembly frame 91, the winding wheel 102 is fixedly sleeved on the axle 101, one end of the two pull wires 103 are connected to the winding wheel 102, and the other end is respectively connected to two movable push plates 93, the second gear 104 is fixedly sleeved on the axle 101, the movable rack 105 is slidably set on the assembly frame 91, and the movable rack 105 and the second gear 104 are meshed with each other, the push rod 106 is fixed on one end of the movable rack 105, and the movable rack 105 and the assembly frame 91 are connected by a tension spring 107. During the contact between the push rod 106 and the plurality of protrusions 114, the two movable push plates 93 can alternately approach and move away from each other. During this process, the two movable push plates 93 can continuously push the end positions of the cables so that the end positions of multiple cables are arranged neatly to prepare for subsequent crimping operations. The pushing process is automatically achieved through mechanical components without manual intervention.

[0044] The control unit is arranged on the side of the terminal crimping machine 1, and the control unit includes a strip plate 111, a fixed rack 112, a transverse plate 113, a plurality of protrusions 114 and a magnetic plate 116. The strip plate 111 is fixed on the side of the terminal crimping machine 1, the fixed rack 112 and the transverse plate 113 are both fixed on the side of the strip plate 111, the fixed rack 112 is arranged opposite to the first gear 85, each protrusion 114 is fixed on the transverse plate 113, each protrusion 114 is provided with an arc surface, and a plurality of protrusions 114 are distributed in a linear array along the length direction of the transverse plate 113, and a plurality of protrusions 114 are arranged opposite to the top rod 106, and there is a gap between two adjacent protrusions 114. The magnetic plate 116 is fixed on the side of the strip plate 111 through the connecting block 115, and the magnetic plate 116 is made of a magnet.

[0045] The specific working principle of the present invention is as follows:

[0046] When the portable cable crimping terminal device proposed by the present invention is in use, in the initial state, the linear slide 3 is located at the end position of the linear drive module 2. At this time, the linear slide 3 and the wire feeding plate 61 are away from the cable insertion port on the terminal crimping machine 1. When multiple cables of the same specification need to be crimped, the staff places the multiple cables between the wire feeding plate 61 and the wire pushing plate 75, and then starts the linear drive module 2. When the linear drive module 2 is running, it drives the linear slide 3 to move. When the linear slide 3 moves, it drives the wire feeding plate 61 to move through the connecting rod, and the wire pushing plate 75 will also move accordingly. In the initial state, the first gear 85 is not meshed with the fixed rack 112. In the initial stage of the movement of the wire feeding plate 61, the first gear 85 will move to a position meshed with the fixed rack 112 and rotate under the action of the fixed rack 112. When the first gear 85 rotates, it will drive the transmission shaft 83 to rotate. When the transmission shaft 83 rotates, it drives the rotating shaft 82 to rotate through two mutually meshing bevel gears 84. When the rotating shaft 82 rotates, it can also drive the reciprocating screw rod 72 to rotate. Under the limiting action of the guide rod 73, the movable plate 74 cannot follow the reciprocating screw. The rod 72 rotates and moves back and forth under the rotation of the reciprocating screw rod 72, which causes the wire pushing plate 75 to move back and forth accordingly. During the reciprocating movement of the wire pushing plate 75, several rollers 77 thereon can push the cables between the wire feeding plate 61 and the wire pushing plate 75 to move. When the cables move to a position facing the sliding sleeve 63, the cables will fall into the sliding sleeve 63. In summary, during the reciprocating movement of the wire pushing plate 75, several cables can fall into several sliding sleeves 63 respectively under the movement of the wire pushing plate 75, thereby realizing automatic arrangement of the cables.

[0047] Furthermore, with the movement of the linear slide 3 and the wire feeding plate 61, the first gear 85 will separate from the fixed rack 112, and the push rod 106 will come into contact with a plurality of protrusions 114. When the push rod 106 and the protrusions 114 are in contact, the protrusions 114 will hinder the movement of the push rod 106, so that the push rod 106 moves along the surface of the protrusions 114. When the push rod 106 moves, it can drive the movable rack 105 to move. When the push rod 106 moves to two adjacent protrusions, 114, the protrusion 114 no longer squeezes the push rod 106, and the movable rack 105 will be reset under the elastic force of the tension spring 107. Therefore, under the action of several protrusions 114, the push rod 106 can move back and forth during the linear movement, and drive the movable rack 105 to move back and forth. The movable rack 105 can drive the second gear 104 to rotate forward and reverse continuously during the reciprocating movement, which makes the shaft 101 and the winding wheel 102 rotate forward and reverse accordingly. When the winding wheel 102 rotates forward, the winding wheel 102 can reel in two pull wires 103, and at this time, the two pull wires 103 can pull the two movable push plates 93, so that the two movable push plates 93 are close to each other. When the winding wheel 102 reverses, the winding wheel 102 no longer reels the two pull wires 103. Lacking the traction of the two pull wires 103, the two movable push plates 93 will reset under the action of the corresponding springs. Based on the above process, in the process of the top rod 106 contacting the plurality of protrusions 114, the two movable push plates 93 can alternately approach and move away from each other. In this process, the two movable push plates 93 can continuously push the end positions of the cables, so that the end positions of multiple cables are arranged neatly to prepare for subsequent crimping operations. The pushing process is automatically achieved through mechanical components without manual intervention.

[0048] As the linear slide 3 and the wire feeding plate 61 continue to move, the push rod 106 will separate from the several protrusions 114, and the two movable push plates 93 will also stop moving. When one end of the wire feeding plate 61 moves to a position opposite to the cable insertion port on the terminal crimping machine 1, the magnetic baffle 95 also happens to move to a position opposite to the magnetic suction plate 116. At this time, the magnetic baffle 95 will move upward under the attraction of the magnetic suction plate 116 and be adsorbed on the magnetic suction plate 116. When the magnetic baffle 95 is adsorbed on the magnetic suction plate 116, the magnetic baffle 95 is completely offset from the wire outlet 94. At this time, the magnetic baffle 95 will not block the wire outlet 94, so that the cable can be smoothly inserted into the terminal crimping machine 1.

[0049] Furthermore, when the cable at the end position moves to the position opposite to the cable insertion port on the terminal crimping machine 1, the linear drive module 2 stops running, and the linear slide 3 and the wire feeding plate 61 also stop moving. At this time, the push cylinder 5 starts running and pushes the opposite connecting plate 65 to move. When the connecting plate 65 moves, it can drive the sliding sleeve 63 to move, and the cable located on the sliding sleeve 63 will also move accordingly, which enables the end of the cable to be inserted into the cable insertion port on the terminal crimping machine 1. When the end of the cable completes the insertion action, the terminal crimping machine 1 automatically crimps the cable. After the crimping action is completed, the pushing cylinder 5 is reset, and the linear slide 3 continues to drive the wire feeding plate 61 to move until the next cable moves to the position opposite the cable insertion port. At this time, the pushing cylinder 5 starts to operate again and pushes the opposite connecting plate 65 to move again until the cable is inserted into the cable insertion port again. In summary, the periodic operation of the linear slide 3 and the pushing cylinder 5 realizes the crimping process of multiple cables without manual pushing of cables. The operation is convenient, the labor intensity of manual labor is reduced, and the working efficiency of the device is improved.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
