The technical scheme of the present invention has at least the following advantages and beneficial effects:

1. The present invention adopts the three-in-one system of tangent, string, plug, and crimp. For most factory production lines, there are fully automatic or semi-automatic machines that integrate tangent and crimping, and there are also independent crimping machines. The tangent, string, plug, and pressure end integrated machine introduced by the plug requires manual connection of the sealing plug stations. The problem of bad and waste of materials and the failure of subsequent crimping terminals caused by the bending of copper wires exposed outside the sealing plug, etc., are time-consuming and labor-intensive, and waste human resources. In this process, the machine is used instead of manual operation, which avoids various risks and errors in the manual production process, and greatly improves the efficiency of the sealing plug in series.

2. In order to improve the efficiency of the present invention, a wire-stripping device is designed for this machine. The design of this device is considered from two aspects. At present, there is no system machine that integrates the operation of the sealing plug in series and the crimping terminal. It can be said that It is all done by manually connecting the sealing plug and then moving it to the end-pressing machine to perform the end-pressing operation. Bending, and in this three-in-one machine for the tangent, string, plug, and pressure end, a string plug system is added to the middle link, and the copper wire of the tangent bundle may be bent after the sealing plug is connected in series. These two aspects will cause In the process of crimping the terminal, it is necessary to manually straighten the copper wire. If the manual straightening operation is not carried out, it may lead to unqualified items such as no core wire crimping, leakage of the core wire, etc. Therefore, the wire harness copper wire must be accurate during the crimping process. To maintain its straight state, during the crimping process, the copper wire of the wire head is easy to bend, which may lead to unqualified items such as no-core wire crimping and core wire leakage. It can keep the copper wire in a straight state, prevent unqualified phenomena such as leakage of the core wire, and complete the straightening operation of the copper wire. Compared with the pressing end after the sealing plug is connected in series, the design of this wire drawing device has a very large effect, which can prevent the failure of the later work station from reciprocating, and can obviously improve the efficiency.

3. In order to improve the efficiency of the present invention, the machine is also equipped with a length measuring sensor. In order to prevent the failure of the crimping process, the length of the wire head copper wire crimping during the crimping process cannot be fully guaranteed, which may cause the terminal to be covered with glue. , terminal hanging neck, terminal cutting head is too long, no core wire crimping and other unqualified items, install a length measuring sensor 10 on the right side of the crimping tool to keep the front copper wire within the range of 0 ~ 0.5mm to prevent When the terminal cutting head is too long and other unqualified phenomena, when the position of the pressing end is normal, the length measuring sensor will be normal. When the position of the pressing end is too long or too short, the length measuring sensor 10 on the right side will alarm, effective The failure of the pressing end is avoided and the efficiency is improved.

4. In order to improve the efficiency of the present invention, the machine is also designed with a baffle plate and a sliding wire collecting plate. For the excessively cut wire, it is easy to cause the wire to be rolled after the cutting, and it is necessary to manually connect the tail of the collecting plate. It is time-consuming and labor-intensive, and the efficiency is extremely low. Therefore, a baffle is added at the machine collecting steel plates, and a sliding wire gathering plate is added at the lower end to gather the wire harnesses, which can significantly reduce the coiling of the wire harnesses and improve the efficiency.

As a preferred embodiment of the present invention, the present invention discloses an operation method of a three-in-one machine for tangent, string-plugging, and pressing ends, comprising the following steps:

1) Before performing the tangent series connection sealing plug crimping terminal, it is necessary to carry out the inspection operation of the relevant machine, introduce the wire harness into the wire feeder 4 in advance and wait, place the sealing plug in the drum of the plug series plug 8 and add a small amount of oil. , install the terminal to be crimped through the terminal turntable sleeve 13 and the terminal inlet and outlet channel 11, and introduce the paper sheet between the terminal and the terminal into the paper sheet collector 12;

2) Turn on the power supply, and the wire harness enters through the wire feeder 4. There is an automatic propulsion device in the wire feeder 4 to realize the stable wire feeding operation of the wire harness. Cut and peel off both ends of the required wire harness;

3) When one end of the wire harness enters the cutter position, start the first wire harness end cutting, due to the continuous automatic advancement of the wire feeder 4, when the other end of the cut wire harness is at the cutter position, start the second wire harness end. Cut, cut, and then remove the cut wire harness sheath through the wire stripper 6, when one end of the wire harness enters the position of the wire stripper 6, start the first wire harness end stripping operation;

4) Due to the continuous and automatic advancement of the wire feeder 4, when the other end of the cut wire harness is at the position of the wire stripper 6, start the second wire harness end stripping operation to strip the wire. 7 performs lateral displacement so that the wire harness can be perfectly connected with the wire clamp b 9. When the wire clamp a 7 moves the cut and stripped wire harness laterally, the wire clamp b 9 can be rotated to operate the clamp. The wire harness is cut at the residence, and the wire harness can be moved to one side during the operation of the conveyor belt, so that the entire wire harness can be kept as straight as possible, and the cut wire harness can be transported to the next station. The wire harness of the plugs reaches the plug stringer 8 for tandem sealing plugs.

Further, the design of the sealing plug in the present invention is the main aspect. Since most factories now operate the sealing plugs in series by manual manual connection of the sealing plugs, no machine can be used, and the manual connection is done manually. During the sealing plug process, firstly, the sealing plugs of the required wire harnesses need to be manually oiled. Then, since there is no integrated machine for cutting and connecting the sealing plugs in the factory, the cut wire harnesses can only be manually moved to the serial connection. The sealing plug station continues to operate, because the wire harness cut in the previous station may bend the copper wire of the required wire harness in the process of manual movement, thus causing the need to manually straighten the copper wire in the process of connecting the sealing plug in series. , Manually straightening the copper wire may cause damage to the hand, and the hand must be damaged after a long-term straightening operation. If the copper wire is not straightened due to manual errors, the copper wire of the required wiring harness may be exposed, and may even be tied The hand is broken, which in turn causes the failure of the pressing end of the subsequent station. It can be seen that the manual operation of connecting the sealing plugs in series is time-consuming and labor-intensive, and it is very easy to cause danger. Therefore, a component that connects the sealing plugs in series and is also a system part integrated with the tangent is particularly important.

As a preferred embodiment of the present invention, a small amount of oil is manually added to the drum 801 before the machine is running. After the machine is running, the drum 801 is driven to rotate by the small motor 2. The sealing plug keeps moving in the drum 801 and passes through the drum 801 The arc-shaped blade 803 rotates the sealing plug together with the drum 801. A sliding plate 802 is arranged in the middle of the drum 801, and the sealing plug that falls on the upper side can be slid down through the sealing plug set below the collection plate 804 and lined up in a row.

At the same time, the thread clamp a 7 guides the wire into the position that can be controlled by the thread clamp b 9, the clamped wire harness is removed from the thread clamp a 7 through the thread clamp b 9, and the thread clamp b 9 is clamped. The trapped wire is connected in series with the sealing plug in the sliding collecting plate 804. After the sealing plug is connected in series, the wire tie of the stringed sealing plug is removed to the wire-pulling device 19 through the wire clamp b9, and then The wire harness connected with the sealing plug is introduced into the pressing end station through the rotating shaft for the pressing end operation. When placing the pressing end tool under the pressing end tool, a length measuring sensor 10 is installed on the right side to detect the failure of the pressing end end.

According to the wire harness model, select a reasonable terminal for the rear end crimping operation. The wire drawing device is also an important part of this invention. From two aspects:

1) In the first aspect, for the current factory, there is no system machine that integrates the operation of connecting the sealing plug in series with the crimping terminal. It can be said that the sealing plug is manually connected in series and then moved to the end-pressing machine for end-crimping. Operation, the wire harness connected with the sealing plug in series in the sealing plug station may cause the bending of the copper wire of the required wire harness in the process of manual movement;

2) In the second aspect, in this three-in-one machine for tangent, string-plugging, and pressing ends, a string-plug system is added to the middle link, which may cause the copper wire of the tangent bundle to be bent after the sealing plug is connected in series; these two All aspects will result in the need to manually straighten the copper wire in the process of crimping the terminal. The wire harness copper wire keeps its straight state accurately;

As a preferred embodiment of the present invention, during the crimping process, the copper wire at the end of the wire is easy to bend, which may lead to unqualified items such as no-core wire crimping, leakage of the core wire, etc., install a stroking wire on the left side of the crimping tool The device 19, the fixing plate 1902 plays a fixed role, the wire-pulling arm 1903 is controlled by the control box 1901, and the wire-pulling arm 1903 can be moved back and forth, and then the rubber ring 1904 is used to straighten the wire harness, which can keep the copper wire in a straight state, To prevent unqualified phenomena such as core wire leakage, complete the straightening operation of the copper wire.

Then use the wire clamp b 9 to place the straightened wire harness on the position of the crimping end, in order to prevent the failure of the crimping process, the length of the wire head copper wire crimping during the crimping process cannot be fully guaranteed, which may cause the terminal to be covered with glue. For unqualified items such as connection, terminal hanging neck, terminal cutting head is too long, no core wire crimping, etc., a length measuring sensor 10 is installed on the right side of the crimping tool. The length measuring sensor 10 here is also installed in this invention. It is an important part to keep the front-end copper wire within the range of 0-0.5mm to prevent the occurrence of unqualified phenomena such as the terminal cutting head being too long. When the position of the pressing end is normal, the length measuring sensor 10 will be normal. When the length is too long or too short, the length measuring sensor 10 on the right side will alarm, which effectively avoids the failure of the pressing end and improves the efficiency.

Further, after the end of pressing, the front part of the wire harness is moved to the wire harness collection plate 22 by the wire clamp b 9, and the rear part of the wire harness is moved to the wire harness collection plate 22 through the conveyor belt. It causes the wire to be coiled after cutting. After the wire harness is coiled, the coiled wire harness needs to be manually pulled out one by one, and in the process of pulling out, it is easy to cause the exposed copper wire at the end of the wire to be bent, and the copper wire needs to be manually stretched when it is bent. Straight copper wire operation, manual straightening of the copper wire may cause damage to the hand, and may even puncture the hand.

If the copper wire is not straightened due to manual error, the copper wire of the required wire harness is bent, so it is necessary to manually connect the tail of the collecting plate, and the manual tail is manually connected, which is time-consuming and laborious, so add a steel plate to the machine. baffle plate 23, and a sliding wire gathering plate 24 is added at the lower end to gather the wire harnesses. The installation of the baffle plate and the wire gathering plate here is also an important part of this invention, which can significantly reduce the coiling of the wire harness and improve the efficiency.

The above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Any modifications or partial substitutions that do not depart from the spirit of the present invention should be included in the scope of the claims of the present invention.
