[0049] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0050] This embodiment relates to a terminal crimping device. In terms of the overall structure, the terminal crimping device includes a frame 1, a plurality of terminal installation mechanisms arranged on the frame 1 at intervals along the first direction, a crimping mechanism slidably arranged on the frame 1 along the first direction, a first driving part 7 corresponding to each of the plurality of terminal installation mechanisms one by one, and a second driving part 11 for driving the crimping mechanism to slide.

[0051] Among them, each terminal installation mechanism includes a terminal conveying part arranged at the power output end of the corresponding first driving part 7 and an installation part for installing the crimping die 10. And the first driving part 7 can drive the terminal installation mechanism to slide along the second direction and switch between the standby position and the working position. The terminal conveying part can convey the terminals into the crimping die 10. The crimping mechanism includes a pressing part 12 arranged at the power output end of the second driving part 11 and a wire harness conveying part arranged on the pressing part 12. The second driving part 11 can drive the crimping mechanism to move to any terminal installation mechanism in the working position. The wire harness conveying part can convey the wire harness 14 into the crimping die 10, and the pressing part 12 can crimp the terminals and the wire harness 14 in the crimping die 10 together.

[0052] The terminal crimping device described in this embodiment can install various types of terminals by setting multiple terminal installation mechanisms. The first driving part 7 drives the terminal installation mechanism to switch between the standby position and the working position, and the second driving part 11 drives the crimping mechanism to move to any terminal installation mechanism in the working position and can move the crimping mechanism to the corresponding terminal installation mechanism according to requirements, so as to facilitate crimping the terminal and the corresponding wire harness 14 together. Compared with the prior art, there is no need to replace the terminal installation mechanism, the terminal and the wire harness 14, so the time for model change can be saved, and thus the crimping efficiency of the terminal and the wire harness 14 can be improved.

[0053] Based on the above overall introduction, an exemplary structure of the terminal crimping device described in this embodiment is as Figures 1 to 3 shown in the figure. The terminal installation mechanism and the crimping mechanism are arranged on the top of the frame 1. The first direction is preferably the length direction or the width direction of the frame 1, and the second direction is perpendicular to the first direction. The specific standby position of each terminal installation mechanism is on one side of the frame 1, and the crimping mechanism is arranged on the other side of the frame 1 relative to the terminal installation mechanism. The number of terminal installation mechanisms in this embodiment can be four as shown in the figure, or can be adaptively increased or decreased according to the usage requirements. Among them, different models of terminals are respectively wound on each terminal mounting disk 3.

[0054] As a preferred implementation manner, the terminal conveying part in this embodiment includes a base 8 arranged at the power output end of the first driving part 7, a conveying plate 2, a terminal mounting disk 3 and a paper winder 4 arranged on the base 8. The terminal mounting disk 3 is located above the conveying plate 2, and the paper winder 4 is located below the terminal mounting disk 3. Corresponding to each terminal installation mechanism, a first detection part 8051 is arranged on the frame 1, and the first detection part 8051 can send a signal to the control part to enable the control part to control the action of the paper winder 4. Here, the setting of the terminal mounting disk 3 and the paper winder 4 is conducive to the unwinding of the terminal and the winding of the separator paper, and the setting of the first detection part 8051 is conducive to the control part to control the action of the paper winder 4, so as to facilitate the unwinding of the terminal.

[0055] Specifically, as Figure 3 and Figure 4 shown in the figure, a support plate 101 is arranged on the top of the frame 1. The base 8 is located on the support plate 101 and is rectangular and extends along the second direction. The first driving part 7 is respectively located in the installation cavity below the support plate 101. Preferably, the first driving part 7 can adopt a first motor in the prior art that can output linear driving force. Corresponding to each base 8, through holes 1011 extending along the second direction are respectively arranged on the support plate 101, and the bottom of the base 8 is specifically connected to the power output end of the first driving part 7 through a plurality of connecting blocks passing through the through holes 1011.

[0056] Here, the first driving part 7 drives the connecting block to slide in the through hole 1011, so that the terminal mounting mechanism can reciprocally slide between the standby position at one end of the through hole 1011 and the tooling position at the other end of the through hole 1011. In addition, the guiding sliding of the connecting block in the through hole 1011 is also beneficial to improving the stability of the base 8 during sliding. In addition to using a motor, the first driving part 7 can also use other power devices that can output linear driving force.

[0057] Still referring to Figure 4 As shown in

[0058] In this embodiment, after the terminals and the separator paper unwound from the terminal mounting disk 3 are separated, the terminals enter the feeding channel, and the separator paper is also wound on the reel 4. To improve the winding effect of the reel 4, an arc-shaped guiding plate 205 is provided on the side of the conveying housing 204 facing the reel 4. The free end of the guiding plate 205 is located above the reel 4, and the separator paper separated from the terminals can be wound on the reel 4 under the guidance of the guiding plate 205.

[0059] As a preferred embodiment, as Figure 4 and Figure 5 shown in

[0060] Among them, the mounting bracket 801 is arranged at the feeding end of the horizontal part 202, and one end of the load-bearing plate 804 far from the vertical part 201 is rotatably arranged on the mounting bracket 801. To improve the use effect of the load-bearing plate 804, in this embodiment, a limiting part is provided on the mounting bracket 801, and the load-bearing plate 804 is lapped on the limiting part, and a gap for the terminals to pass through is formed between the load-bearing plate 804 and the conveying plate 2. Through the limiting part, it is beneficial to improve the convenience of the terminals passing through. In addition, a gap for the terminals to pass through is formed between the load-bearing plate 804 and the conveying plate 2, which is beneficial to the conveying of the terminals. At the same time, when the material of the terminals is insufficient, the terminals can easily lift the load-bearing plate 804, which is beneficial for the first detection part 8051 to cooperate with the control part to start the paper reel 4.

[0061] In terms of the specific structure, the limiting part includes limiting platforms 802 arranged on the mounting bracket 801 and located on both sides below the load-bearing plate 804. The structure of the limiting platform 802 here is simple and convenient for layout and implementation. In addition, a limiting rod 803 can also be arranged on the mounting bracket 801 above the free end of the load-bearing plate 804 to limit the upward rotation angle of the load-bearing plate 804 through the limiting rod 803. That is to say, the limiting platform 802 and the limiting rod 803 cooperate to limit the rotation angle of the load-bearing plate 804.

[0062] In this embodiment, the structure of the detection plate 206 is as Figure 5 shown in the figure. Relative to the connecting part 203, the detection plate 206 is arranged on the other side of the conveying housing 204. The detection plate 206 is also arc-shaped and has the same shape as the connecting part 203. The top end of the detection plate 206 is connected to the conveying housing 204, and the bottom end is located on the rotation path of the load-bearing plate 804. The measured block 207 is located above the bottom end of the detection plate 206.

[0063] During the upward rotation of the load-bearing plate 804, the feeding end of the load-bearing plate 804 can push the detection plate 206 upward, causing the detection plate 206 to tilt upward, and further causing the measured block 207 to move upward. To improve the conveying effect of the terminals, a tilted-up part is provided on the feeding plate of the load-bearing plate 804. Due to the setting of the tilted-up part, the vertical distance between the feeding end of the load-bearing plate 804 and the conveying plate 2 is gradually reduced.

[0064] As Figure 4 shown in the figure, a vertical plate 805 is provided on the base 8 on one side of the conveying plate 2 and downstream of the load-bearing plate 804. The first detection part includes a position sensor arranged on the vertical plate 805, and this position sensor can adopt products in the prior art. When the bottom end of the detection plate 206 is not tilted up, the measured block 207 is outside the detection path of the position sensor. When the rear end of the detection plate 206 tilts upward to make the measured block 207 located on the detection path of the position sensor, the measured block 207 can be detected.

[0065] During specific use, the terminal is intermittently unrolled. In the initial state after unrolling, the terminal is relatively loose, and the terminal is arranged close to the vertical part 201 and the connecting part 203 of the conveying plate 2. When the terminal becomes shorter and shorter as it is conveyed, the terminal is tightened and attached to the load-bearing plate 804, driving the load-bearing plate 804 to rotate, and then pushing the detection plate 206 to act, thereby driving the measured block 207 to be located on the detection path of the first detection part 8051. This indicates that the terminal needs to be unrolled continuously. At this time, the first detection part 8051 sends a signal to the control part to enable the control part to control the paper reel 4 to act, so that the isolation paper drives the terminal to be unrolled, which is conducive to realizing the continuous feeding and crimping of the terminal, and thus conducive to improving work efficiency. The control part can adopt a programmable controller in the prior art. The control part is electrically connected to both the first detection part 8051 and the paper reel 4, and has good performance in use.

[0066] As a preferred implementation manner, a pressing plate 9 is slidably arranged on the conveying plate 2, and a first elastic member 905 is pushed against the pressing plate 9. Under the action of the first elastic member 905, the pressing plate 9 is pressed against the conveying plate 2 and can be pushed upward by the conveyed terminal. Through the first elastic member 905, the pressing plate 9 can be pressed against the terminal, which is conducive to improving the stability of the terminal during conveying, and thus conducive to improving the crimping effect between the terminal and the wire harness 14.

[0067] As shown in the figure, the pressing plate 9 includes a first part 901 and a second part 902 arranged at intervals along the conveying direction of the terminal. Among them, the first part 901 is located above the conveying plate 2, the second part 902 is attached to the conveying plate 2, and the pressing plate 9 further includes an intermediate part 903 connected between the first part 901 and the second part 902. A guiding column extending in the height direction is arranged on the mounting frame 801, and the first part 901 is slidably arranged on the guiding column, so that the pressing plate 9 can only slide up and down.

[0068] For the convenience of arranging and installing the first elastic member 905, as Figure 4 shown in the figure, a mounting block 904 is arranged above the second part 902 of the pressing plate 9. The first elastic member 905 is a first spring arranged at the bottom of the mounting block 904, and the bottom end of the first spring abuts against the second part 902. When the terminal passes through, the second part 902 is pushed by the terminal to move the pressing plate 9 upward, and the first spring is compressed and stores energy, and the pressing plate 9 is pressed against the conveyed terminal.

[0069] In addition, a second detection part is provided on the conveying plate 2, and the second detection part is used to detect the terminals on the conveying plate 2. Specifically, in implementation, the second detection part can also be a position sensor arranged on the mounting block 904, and a detection port located on the detection path of the second detection part is provided on the pressing plate 9. During the process of the terminals being conveyed on the conveying plate 2, the second detection part can detect the terminals. When the second detection part fails to detect the terminals, it indicates that the terminal mounting disc 3 needs to be replaced. The setting of the second detection part in this embodiment facilitates the continuous feeding of the terminals, thereby facilitating the improvement of the processing efficiency.

[0070] In this embodiment, the crimping die 10 is located downstream of the pressing plate 9, and it can adopt products in the prior art, such as Figure 6 As shown in, the crimping die 10 has a feeding channel located on the terminal conveying path, a lower jaw 1001 at the discharging end of the feeding channel, a bearing rod 1002 slidably arranged above the lower jaw 1001, and an upper jaw 1003 corresponding to the lower jaw 1001 is provided at the bottom end of the bearing rod 1002. As for other structures of the crimping die 10 not mentioned in this embodiment, they can all refer to the prior art.

[0071] As a preferred implementation manner, the installation part includes a fixed block 806 and a locking block 807 spaced apart on the base 8, and a second elastic member 808 arranged between the locking block 807 and the base 8. The fixed block 806 can abut against one side of the crimping die 10, the locking block 807 is slidably arranged on the base 8, and under the pushing of the second elastic member 808, the locking block 807 abuts against the other side of the crimping die 10. Here, the cooperation of the fixed block 806 and the locking block 807, and the pushing of the second elastic member 808 on the locking block 807 are beneficial to improving the installation effect of the crimping die 10.

[0072] In terms of the specific structure, as shown in Figure 6 and Figure 7 The fixed block 806 is located at the end of the crimping die 10 away from the conveying plate 2, and the locking block 807 is arranged opposite to the fixed block 806 on the side of the crimping die 10 close to the conveying plate 2. Among them, the locking block 807 is in a long strip shape, and a sliding groove for the locking block 807 to slide is provided on the base 8. To facilitate the arrangement of the second elastic member 808, a convex block 8071 is provided at the top of the locking block 807 close to the conveying plate 2, and the convex block 8071 is slidably arranged on the base 8 through a guide post 8072 provided on itself. The second elastic member 808 is a second spring sleeved on the guide post 8072 and located between the convex block 8071 and the base 8, and the second spring applies a force towards the crimping die 10 to the locking block 807, thereby facilitating the pre-positioning of the crimping die 10 on the base 8.

[0073] In order to further improve the installation effect of the crimping die 10 on the base 8, in this embodiment, a locking cylinder 809 is provided on the base 8, and a tightening block 8091 is provided at the power output end of the locking cylinder 809. The locking cylinder 809 can drive the tightening block 8091 to push the locking block 807 toward the side of the fixed block 806. The arrangement of the locking cylinder 809 and the tightening block 8091 here is conducive to further improving the installation firmness of the crimping die 10 on the base 8.

[0074] Specifically, refer to Figure 6 As shown in the figure, the locking cylinder 809 is specifically installed below the base 8, the middle part of the abutting block 8091 is rotatably arranged on the base 8, the power output end of the locking cylinder 809 is hingedly connected to the bottom of the abutting block 8091, so that the abutting block is driven to rotate by the extension and contraction of the cylinder rod. The top end of the abutting block can push the locking block 807 when rotating, so that the locking block 807 is firmly abutted against the other side of the crimping die 10.

[0075] As a preferred embodiment, Figure 1 and Figure 8 As shown, a fixing frame 102 is provided on the frame 1, and the crimping mechanism is slidably arranged on the fixing frame 102 along the first direction. Preferably, the second driving part 11 can adopt the lead screw 1101 motor in the prior art. In terms of specific structure, mounting plates 103 are respectively provided on both sides of the crimping mechanism, and the lead screw 1101 of the second driving part 11 is rotatably arranged on the mounting frame 801 and is screwed and connected with the mounting plate 103. In addition, a limiting column 1021 is provided on the mounting frame 801 through each mounting plate 103. The second driving part 11 drives the lead screw 1101 to rotate, and can drive the crimping mechanism to slide along the first direction through the mounting plate 103. At the same time, under the action of the limiting column 1021, the crimping mechanism can only slide along the first direction, and will not rotate around the axis of the lead screw 1101, thereby having better stability.

[0076] As a preferred embodiment, Figure 10 As shown in , the press-fitting part 12 in this embodiment includes a mounting seat 1206 arranged at the power output end of the second driving part 11, a third driving part 5 arranged on the mounting seat 1206, an output shaft 1202 connected to the power output end of the third driving part 5, a punch 1201 slidingly arranged on the mounting seat 1206 along the up-down direction, and a transmission rod 1204 connected between the punch 1201 and the output shaft 1202. An eccentrically arranged connecting column 1203 is arranged on the output shaft 1202, one end of the transmission rod 1204 is connected to the connecting column 1203, and the other end is connected to the punch 1201 through a ball head 1205. The arrangement of the third driving part 5, the punch 1201, the transmission rod 1204 and the connecting column 1203 on the press-fitting part 12 here is conducive to applying downward pressure to the crimping die 10.

[0077] Specifically, as shown in Figure 10 , the mounting base 1206 is arranged between two fixed plates. The third driving part 5 can adopt a motor, which can output a rotational driving force and drive the connecting column 1203 to rotate through the output shaft 1202. The transmission rod 1204 is slidably arranged in the mounting base 1206 in the height direction. The top end of the transmission rod 1204 is sleeved on the connecting column 1203, and the bottom end is connected to the punch 1201 through a ball head 1205. When the connecting column 1203 is driven to rotate with the power output end of the third driving part 5, it can drive the transmission rod 1204 and the punch 1201 to slide downward, thereby pressing down the crimping die 10.

[0078] As a preferred embodiment, the wire harness conveying part includes a fourth driving part 6 arranged on the pressing part 12, a fifth driving part 15 arranged on the power output end of the fourth driving part 6, a sixth driving part 16 arranged on the power output end of the fifth driving part 15, and a clamp 13 arranged on the power output end of the sixth driving part 16. Among them, the fourth driving part 6 can output a linear driving force along the second direction, the fifth driving part 15 can output a linear driving force along the up and down direction, the sixth driving part 16 can output a rotational power, and the clamp 13 is used for clamping the wire harness.

[0079] In terms of the detailed structure, referring to Figure 9 , Figure 11 and Figure 12 , a first connecting plate 104 is arranged on one side of the mounting base 1206. The wire harness conveying part is specifically arranged on one side of the first connecting plate 104. A first sliding rail 1041 extending along the second direction is arranged on the first connecting plate 104. The wire harness conveying part includes a moving seat 105 slidably arranged on the first sliding rail 1041. The fourth driving part 6 and the wire harness conveying part are arranged on the other side of the first connecting plate 104 opposite to each other.

[0080] Preferably, the fourth driving part 6 includes a motor, a lead screw 106 rotatably arranged on the first connecting plate 104, and an intermediate block 1061 screwed on the lead screw 106. The intermediate block 1061 extends across the first connecting plate 104 and is connected to the moving seat 105. The power output end of the fourth driving part 6 and the lead screw 106 are connected by a chain drive. The fourth driving part 6 can drive the lead screw 106 to rotate and drive the moving seat 105 to slide along the second direction, thereby outputting a linear driving force through the intermediate block 1061.

[0081] As shown in Figure 12As shown in the figure, a second slide rail 1051 extending in the vertical direction is provided on the moving seat 105, and a second connecting plate 107 slidably guided on the second slide rail 1051 is provided on the moving seat 105. The sixth driving part 16 is specifically arranged on the second connecting plate 107. The fifth driving part 15 can drive the second connecting plate 107 to slide up and down along the second slide rail 1051, so as to drive the sixth driving part 16 and the clamping jaw 13 to slide up and down. In specific implementation, the fifth driving part 15 can adopt a cylinder, and the cylinder rod is connected to the second connecting plate 107, which has the advantages of simple structure and convenient layout and implementation.

[0082] Preferably, as Figure 12 shown in the figure, the clamping jaw 13 is arranged at the power output end of the sixth driving part 16 through a belt transmission mechanism. Among them, the belt transmission mechanism includes a belt 1601 sleeved on the rotating shaft of the clamping jaw 13 and the power output end of the sixth driving part 16. The sixth driving part 16 can drive the clamping jaw 13 to rotate through the belt 1601, so as to change the crimping angle between the wire harness 14 and the terminal. Of course, in addition to adopting the belt transmission mechanism, a chain transmission mechanism can also be used to replace the belt transmission mechanism, and a good transmission effect can also be achieved at this time. The sixth driving part 16 here preferably adopts a motor, so that it is beneficial to output a linear driving force, thereby rotating the clamping jaw 13, and further beneficial to changing the angle of the wire harness 14 relative to the terminal.

[0083] In this embodiment, the setting of the fourth driving part 6 is beneficial to adjusting the distance between the wire harness 14 and the crimping die 10 in the second direction, and the sixth driving part 16 is beneficial to adjusting the wire harness 14 to the target angle, and the fifth driving part 15 is beneficial to enabling the wire harness 14 to move downward synchronously with the upper clamping jaw 1003, thereby being beneficial to improving the wiring effect between the terminal and the wire harness 14.

[0084] When the terminal crimping device in this embodiment is used, first select the models of the terminal and the wire harness according to the use requirements, then start the first driving part 7 to slide the terminal installation mechanism from the standby position to the tooling position, and make the terminal installation disc 3 perform a first unwinding of the terminal. The second driving part 11 moves the crimping mechanism to a position corresponding to the terminal installation structure. Then the terminal is conveyed on the conveying plate 2 until the terminal is conveyed to the lower clamping jaw 1001 of the crimping die 10. The fourth driving part 6 drives the moving seat 105 to slide in the second direction to a position corresponding to the upper clamping jaw 1003, and then the sixth driving part 16 drives the clamping jaw 13 to rotate 90°, so that the terminal and the wire harness 14 are arranged at 90°. Then the third driving part 5 presses down the punch 1201, so that the punch 1201 presses down the top of the bearing rod 1002. At the same time, the fifth driving part 15 drives the second connecting plate 107 to move downward synchronously with the lower clamping jaw 1001 until the upper clamping jaw 1003 and the lower clamping jaw 1001 cooperate to crimp the terminal and the wire harness 14 together in a horizontal state.

[0085] With the use of the terminal, when the load-bearing plate 804 pushes the detection plate 206 under the action of the terminal, and the measured block 207 is located on the detection path of the first detection part 8051, the paper winder 4 is triggered to wind the isolation paper, and the re-unwinding of the terminal is realized, which is conducive to the continuous use of the terminal.

[0086] The terminal crimping device of this embodiment optimizes its own structure, so that the terminal installation mechanism and the crimping die 10 are placed side by side, and multiple crimping operations can be achieved with one machine (one device can crimp different types of terminals and wire harnesses), and it has good integration and versatility. During the production process, the positions of the terminal installation mechanism and the crimping mechanism can be moved according to the processing requirements to complete the crimping of the terminal and the wire harness 14. At the same time, through the settings of the first driving part 7 and the second driving part 11, the automatic replacement of the terminal installation mechanism and the crimping mechanism can be realized, which is conducive to improving the changeover efficiency. When this terminal crimping device is in use, there is no need to replace the terminal, the wire harness 14, the terminal conveying mechanism, etc. one by one as in the prior art, which greatly saves the time for changeover, thus facilitating the improvement of the crimping efficiency of the terminal and the wire harness 14, as well as the production efficiency.

[0087] The terminal crimping device of this embodiment can realize the production of multiple dies by one device. When producing the same wire harness 14 circuit, the number of changeovers can be reduced several times compared with the existing crimping equipment, which is conducive to improving the changeover efficiency. In addition, this device does not need to change the existing crimping die 10, so there is no need to change the existing chain connection method of the terminal. Since the chain terminal can be well positioned and fixed in the crimping die 10, the stability of the terminal crimping can be ensured, and the crimping quality of the terminal and the wire harness 14 can be guaranteed.

[0088] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
