DETAILED DESCRIPTION

[0050] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0051] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0052] The following describes a crimping die 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0053] like Figure 1 As shown, the crimping mold 100 according to the embodiment of the present invention includes a first mold 101 and a second mold 102 .

[0054] The first mold 101 has a first mold base 1011 and a plurality of first crimping knives 1012, which are arranged at intervals around the circumference of the first mold base 1011 on the outer circumference of the first mold base 1011; the second mold 102 and the first mold 101 can move relative to each other; the second mold 102 has a second mold base 1021 and a plurality of second crimping knives 1022, which are arranged at intervals around the circumference of the second mold base 1021 on the outer circumference of the second mold base 1021; the plurality of second crimping knives 1022 are matched with the plurality of first crimping knives 1021 in a one-to-one correspondence; when the first mold 101 and the second mold 102 move relative to each other to a position of facing each other, each second crimping knife 1022 and its matching first crimping knife 1012 jointly define a crimping portion 103. In this embodiment, the second mold 102 can be arranged below the first mold 101.

[0055] That is to say, a plurality of first crimping knives 1012 and a plurality of second crimping knives 1022 can be matched and combined into a plurality of pairs of crimping dies in a one-to-one manner, and the crimping parts 103 of the plurality of pairs of crimping dies are designed corresponding to various types of terminals; the plurality of crimping parts 103 for crimping corresponding to various terminal models are arranged at circumferential intervals, and the crimping parts 103 can be switched by synchronously rotating the first die base 1011 and the second die base 1021, so that a crimping device equipped with the crimping die 100 can crimp terminals of different types. Then, the first mold 101 and the second mold 102 can move relative to each other. It can be understood that when the second mold 102 moves toward the first mold 101 to a position where it matches with each other, the crimping portion 103 is formed, so that the terminal can be clamped or the crimping portion 103 that has already clamped the terminal and the terminal is passed through the wire can be crimped; it can also be that when the first mold 101 moves toward the second mold 102 to a position where it matches with each other, the crimping portion 103 is formed, so that the terminal can be clamped or the crimping portion 103 that has already clamped the terminal and the terminal is passed through the wire can be crimped. Among them, the position where it matches with each other can be the position where the crimping portion 103 clamps the terminal, or it can be the position where the terminal and the wire are crimped together, that is, the crimping position.

[0056] Therefore, by arranging a plurality of first crimping knives 1012 at circumferential intervals on the first die base 1011, and arranging a plurality of second crimping knives 1022 at circumferential intervals on the second die base 1021, the first crimping knives 1012 and the second crimping knives 1022 are arranged in one-to-one correspondence, and can jointly define the crimping portion 103, so that the plurality of crimping portions 103 of the crimping mold 100 are arranged at circumferential intervals, and by rotating the crimping portion 103, the crimping of terminals of different types can be switched; in this way, when it is necessary to switch to crimping of different terminals, the crimping portion 103 corresponding to the terminal model to be crimped is rotated to a position where the terminal to be crimped can be received and a position where the terminal can be crimped, thereby achieving crimping of terminals of different types.

[0057] Therefore, the crimping die 100 according to the embodiment of the present invention can improve the crimping efficiency of the wire harness processing equipment for terminals of various types, and the various crimping blades are arranged at circumferential intervals, so that the entire crimping die structure is compact and the equipment manufacturing cost can be reduced.

[0058] Specifically, the outer circumferential surface of the first die base 1011 may be provided with a plurality of first mounting grooves 1013 arranged at intervals along the circumference of the first die 1011, and the first mounting grooves 1013 are suitable for mounting the first crimping knife 1012; the outer circumferential surface of the second die base 1021 is provided with a plurality of second mounting grooves 1023 arranged at intervals along the circumference of the second die base 1021, and the second mounting grooves 1023 are suitable for mounting the second crimping knife 1022; the plurality of first mounting grooves 1013 and the plurality of second mounting grooves 1023 are aligned and arranged one by one. The crimping knife can be mounted in the mounting groove by a fastener, such as a bolt or a snap-on connection structure. It can be understood that the crimping knife is arranged on the outer circumferential surface of the first die base 1011 perpendicular to the end face of the first die base 1011. Thus, the crimping knife is circumferentially spaced and detachably mounted on the die base through the mounting grooves arranged at intervals along the circumference. Of course, the crimping knife can also be directly mounted on the die base by a fastener. Then, the plurality of first mounting grooves 1013 and the plurality of second mounting grooves 1023 are aligned and arranged one by one, which can ensure that when the first die base 1011 and the second die base 1021 rotate synchronously, the matching first crimping knife 1012 and the second crimping knife 1022 can always accurately cooperate to form the crimping portion 103, so that when switching to crimp different terminals, only the crimping portion 103 is rotated and switched. In this embodiment, the number of the crimping portion 103, the crimping knife and the mounting grooves is the same, and the specific number is not limited, and can be reasonably designed according to the size of the die base.

[0059] In some examples, the first die holder 1011 and the second die holder 1021 may be polyhedrons, such as disc-shaped, so that a variety of crimping knives can be arranged more compactly and spaced apart on the outer circumference of the disc around the circumference of the disc.

[0060] The following describes a crimping device 10 according to an embodiment of the present invention with reference to the drawings.

[0061] like Figure 1-Figure 5 According to the embodiment of the present invention, the crimping device 10 includes the above-mentioned crimping mold 100, a moving driving member 200, a rotating driving member 300, a clamping driving assembly 400 and a crimping driving assembly 500.

[0062] The moving driving member 200 is connected to the crimping die 100 to drive the crimping die 100 to move between a first position for receiving a terminal and a second position for crimping the terminal with the wire; the rotating driving member 300 is arranged on the moving driving member 200 and is connected to the crimping die 100 to drive the crimping die 100 to rotate at the first position so that each crimping portion 103 receives a terminal of a crimping model corresponding to the crimping portion 103, and also drives the crimping die 100 to rotate at the second position so that the wire to be crimped is provided. Insert into the terminal to be crimped received by the crimping part 103; the clamping drive component 400 is suitable for contacting the second die base 1021 to drive the second die base 1021 to move toward the first die base 1011 so that the crimping part 103 is opened and clamps the terminal at the first position; the crimping drive component 500 is suitable for contacting the first die base 1011 to drive the first die base 1011 to move toward the second die base 1021 so that the crimping part 103 crimps the terminal to be crimped and the wire to be crimped together at the second position.

[0063] That is to say, the first position allows the crimping die 100 to receive the terminal, and the second position allows the crimping die to allow the received terminal to be crimped to be inserted into the wire to be crimped and crimp the two together; then, the movement of the crimping die 100 between the first position and the second position can be driven by the mobile driving member 200. When the crimping die 100 is in the first position, it receives the terminal to be crimped and clamps the terminal to be crimped; when the crimping die 100 is in the second position, it allows the wire to be crimped to be inserted into the terminal to be crimped, and crimps the terminal to be crimped and the wire to be crimped together after the insertion, and the crimping action can be achieved by the crimping driving assembly 500. When selecting the corresponding crimping part 103 for different terminal models, the crimping die 100 can be driven to rotate by the rotating driving member 300. It can be understood that the station for providing the terminal to the crimping die 100 and the station for the crimping die 100 to perform the crimping action are different positions, so that the entire wire harness processing equipment can be reasonably arranged. For example, in this embodiment, the first position and the second position can be Figure 2 Along the front-to-back direction, the second position is located at the rear position, which is close to the crimping drive assembly 500, and the second position is located at the front position, which is far away from the crimping drive assembly 500.

[0064] Therefore, by rotating the crimping part 103, the crimping of terminals of different types can be switched; by setting the crimping mold 100, the movable driving part 200, the rotating driving part 300, the clamping driving component 400 and the crimping driving component 500, the entire crimping device 10 has a compact structure and can use the existing crimping driving parts to perform crimping actions, which can improve the crimping efficiency and reduce the equipment manufacturing cost while realizing the crimping of terminals of different types.

[0065] Specifically, combined with reference Figure 2 and Figure 4 , the first die base 1011 and the second die base 1021 are connected by a rotating shaft 104, and the first die base 1011 and the second die base 1021 are arranged relatively along the axis of the rotating shaft 104; the rotating driving member 300 is connected to the rotating shaft 104 in a transmission manner to drive the rotating shaft 104 to drive the crimping die 100 to rotate; the rotating shaft 104 is pivotally connected to the moving driving member 200, so as to drive the rotating shaft 104 to drive the crimping die 100 to move between the first position and the second position through the moving driving member 200. It can be understood that the rotating shaft 104 penetrates from the center of the cylindrical first die base 1011 and the second die base 1021, connects the first die base 1011 and the second die base 1021, and is arranged relatively along the axis of the rotating shaft 104. That is, the rotating shaft 104 can drive the first mold base 1011 and the second mold base 1021 to rotate synchronously, and the first mold base 1011 and the second mold base 1021 can also move relatively on the rotating shaft 104 along the axis of the rotating shaft 104. Specifically, the rotating shaft 104 can be in a cube shape, or can be connected by a key or a rack, so that the first mold base 1011 and the second mold base 1021 can rotate synchronously and move relatively.

[0066] Among them, combined Figure 2 The mobile driving member 200 may include a first slider 201, a first slide rail 202, a first cylinder 203 and a connecting plate 204. The first slider 201 is slidably disposed on the first slide rail 202. The connecting plate 204 is connected to the first slider 201, and one end of the connecting plate 204 is sleeved on the rotating shaft 104 through a bearing, and the other end is connected to the first cylinder 203. Thus, through the telescopic movement of the first cylinder 203, the connecting plate 204 can drive the rotating shaft 104 to drive the crimping die 100 to move between the first position and the second position. The rotating driving member 300 can be connected to the rotating shaft 104 through a synchronous belt between the first motor 301 and the rotating shaft 104, and the driving rotating shaft 104 drives the crimping die to rotate, thereby switching the position of each crimping part 103, so that each crimping part 103 receives a terminal of a crimping model corresponding to it, and each crimping part 103 that clamps the terminal to be crimped rotates and the power supply line penetrates into the terminal to be crimped. In this embodiment, the first motor 104 is fixed on the connecting plate 204 and moves along with the movement of the connecting plate 204 , so that the synchronous belt between the first motor 104 and the rotating shaft 104 will not be loosened.

[0067] In some examples, combined Figure 3 and Figure 5The clamping drive assembly 400 may include a lifting block 401 and a lifting drive member 402 for driving the lifting block 401 to move upward and downward. The top surface of the lifting block 401 is suitable for contacting the second die base 1021, and the bottom surface of the lifting block 401 is suitable for contacting the lifting drive member 402. Thus, the lifting block 401 is driven to move upward and downward by the lifting drive member 402, so that the lifting block 401 drives the second die base 1021 to move toward the first die base 1011, so that the crimping part 103 closes and clamps the terminal.

[0068] Specifically, the lifting drive member 402 includes a second slide rail 4021, a second slider 4022 and a roller 4023, the second slider 4022 is slidably connected to the second slide rail 4021, and the roller 4023 is pivotally arranged on the second slider 4021; the bottom surface of the lifting block 401 has an inclined surface 401a and two planes 401b, one end of the inclined surface 401a is connected to one of the planes 401b1, and the other end of the inclined surface 401a is connected to the other plane 401b2; when the second slider 4022 slides on the second slide rail 4021, the roller 4023 rolls between the plane 401b1 located at a high position, the inclined surface 401a and the plane 401b2 located at a low position to drive the lifting block 401 to perform a lifting movement, thereby driving the second mold base 1021 to move up and down toward the first mold base 1011, so that the crimping part 103 opens and closes to clamp the terminal. Among them, sliding grooves can be set on both sides of the lifting block 401 to enable the lifting block 401 to move up and down stably.
