Description

Technical Field

[0001] The utility model relates to the technical field of electronic processing equipment, in particular to a terminal limiting mechanism and a wire harness terminal crimping machine. Background Art

[0002] A terminal crimping machine is an electronic processing equipment specially used to crimp wires and terminals to achieve electrical connection. Its working principle is mainly to crimp the end of the wire or cable to the terminal through mechanical pressure to ensure the stable transmission of electrical signals.

[0003] During the crimping process of existing terminal crimping machines, different terminals are used in different devices, and most of the existing terminal crimping machines can only crimp one type of terminal and wire, which will lead to low processing efficiency. In addition, most crimping machines are not equipped with a material blocking component and a pushing component, which makes the feeding rate of the terminal different during the feeding process. In this case, the wire will be squeezed without being connected to the terminal, which not only affects the production efficiency, but also requires secondary processing, which increases the production cost.

[0004] Therefore, how to provide a terminal limiting mechanism and a wire harness terminal crimping machine to solve the defects of the existing terminal crimping machines is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] To this end, the utility model provides a terminal limiting mechanism and a wire harness terminal crimping machine to solve the problem in the prior art that the terminal and the wire are not properly connected due to the lack of a blocking component and a pushing component in the terminal crimping machine.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] The utility model discloses a terminal limiting mechanism and a wiring harness terminal crimping machine, comprising:

DETAILED DESCRIPTION

[0040] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0041] Please refer to Figure 1-Figure 5 Now, a terminal limiting mechanism and a wire harness terminal crimping machine disclosed in the utility model are described. The utility model is composed of seven parts, such as Figure 1 , including a connecting plate 1, a propulsion component 2, a wire pressing component 3, a material blocking component 4, a detection component 5, a feed channel 6 and a feeding component 7. The connecting plate 1 is installed in the shell, and several feeding components 7 are installed on the upper surface of the connecting plate 1. The feed channel 6 is installed on the upper surface of the connecting plate 1. The output end of the feeding component 7 is connected to the feed channel 6. The propulsion component 2 is installed on the upper surface of the connecting plate 1. The propulsion component 2 is arranged below the feed channel 6. The wire pressing component 3 is installed at the end of the feed channel 6. The bottom end of the wire pressing component 3 is installed on the shell, and the material blocking component 4 and the detection component 5 are installed on the upper surface of the wire pressing component 3.

[0042] When the utility model is in use, the feeding component 7 is started to feed the terminal to the feeding channel 6, and the terminal moves along the feeding channel 6 to the bottom of the connecting frame 42, and the driving cylinder 46 pushes the first baffle 43 to move downward so that the bottom of the first baffle 43 abuts against the end of the terminal insulation shell, so that the terminal stops moving. At this time, the next terminal moves to the blocking component 4 and is detected by the detection component 5. Then the driving cylinder 46 pushes the second baffle 44 downward. At this time, the bottom of the second baffle 44 will abut against the end of the insulation shell of the second terminal, thereby limiting the movement of the terminal. The insulation shell of each terminal in the rectangular slot has a different color. The required terminal color signal is detected by the detection probe 51. After the terminal color is detected, the signal is fed back to the driver The cylinder 46 drives the cylinder 46 to start, pulling the first baffle 43 and the second baffle 44 upward. At this time, the lifting cylinder 27 is started, driving the push block 26 to move upward, and the upper end of the push block 26 is against the surface of the insulating shell of the second terminal. After the above action is completed, the propulsion member 23 will drive the movable plate 28 to move through the propulsion rod 21. During the movement of the movable plate 28, the first terminal is pushed toward the wire crimping assembly 3 for crimping. When the second terminal moves to the initial position of the first terminal, the driving cylinder 46 moves the first baffle 43 downward quickly to prevent the second terminal from moving toward the wire crimping assembly 3. At the same time, the lifting cylinder 27 pulls the push block 26 downward, and then the propulsion member 23 pulls the movable plate 28 back to the initial position to prepare for the next terminal feeding.

[0043] In a specific embodiment, Figure 2 The propulsion assembly 2 includes a propulsion rod 21, a support frame 22, a propulsion member 23, a placement plate 24, a drive guide rail 25, a push block 26, a lifting cylinder 27 and a mobile plate 28. The support frame 22 is installed above the connecting plate 1. The propulsion member 23 is installed above the support frame 22. The propulsion member 23 is connected to the propulsion rod 21 in a transmission manner. The placement plate 24 is installed on the wire pressing assembly 3. The placement plate 24 is installed on the wire pressing assembly 3. The drive guide rail 25 is arranged above the placement plate 24. The drive guide rails 25 are arranged in pairs. The drive guide rails 25 are connected to the mobile plate 28 in a transmission manner. The other end of the mobile plate 28 is connected to the end of the propulsion rod 21. Several lifting cylinders 27 are installed on the mobile plate 28. The upper end of the lifting cylinder 27 is connected to the push block 26 in a transmission manner. The setting of the drive guide rail 25 can not only limit the moving direction of the mobile plate 28, but also improve the moving efficiency of the mobile plate 28.

[0044] In a specific embodiment, Figure 3The material blocking assembly 4 includes an L-shaped block 41, a connecting frame 42, a first baffle 43, a second baffle 44, a guide block 45 and a driving cylinder 46. One end of the connecting frame 42 is installed on the wire pressing assembly 3, and a number of L-shaped blocks 41 and a detection assembly 5 are installed on the upper end of the connecting frame 42. The driving cylinder 46 is installed on the other end of the L-shaped block 41. A number of guide blocks 45 are installed at the bottom of the top plate of the connecting frame 42. A guide groove is opened in the guide block 45. A number of first baffles 43 are transmission-connected to the bottom of the driving cylinder 46, and a number of second baffles 44 are transmission-connected to the bottom of the driving cylinder 46. The first baffle 43 is arranged on the right side of the second baffle 44. The first baffle 43 and the second baffle 44 are staggered, and the order of movement of the first baffle 43 and the second baffle 44 is set by driving the cylinder 46, so that each time crimping, only one terminal enters the wire crimping assembly 3. When one terminal enters the wire crimping assembly 3, the first baffle 43 will quickly block the movement of the second terminal. This method not only improves the processing efficiency, but also reduces the situation where the terminal and the wire are not connected together, and reduces rework. The L-shaped block 41 is used to adjust the installation position of the driving cylinder 46. After the terminal enters the guide block 45, the guide groove will shape the terminal to prevent the terminal from entering the wire crimping assembly 3 in the incorrect position.

[0045] In a specific embodiment, Figure 4 The detection assembly 5 includes a detection probe 51 and a support rod 52. The support rod 52 is mounted on the upper end of the connecting frame 42, and the detection probe 51 is mounted on the other end of the support rod 52. The support rod 52 is designed to elevate the detection probe 51 so that the detection range of the detection probe 51 is wider.

[0046] In a specific embodiment, the detection probe 51 is a color sensor. The color sensor is used to determine whether the terminal entering the wire crimping assembly 3 is correct to prevent the terminal from not matching the wire. At the same time, the detection probe 51 can also determine whether the terminal is aligned.

[0047] In a specific embodiment, Figure 5The wire pressing assembly 3 includes a mounting plate 31, a lower clamping member 32, an upper clamping member 33, a moving member 34, a lower mold 35 and an upper mold 36. The mounting plate 31 is mounted on the housing, and the lower mold 35 is mounted above the mounting plate 31. The lower mold 35 is transmission-connected with the upper mold 36. The upper end of the upper mold 36 is connected to the driving device. One end of the propulsion assembly 2 is also mounted on the upper surface of the mounting plate 31. The moving member 34 is mounted on the side of the lower mold 35. One end of the moving member 34 is connected to the upper clamping member 33 and the lower clamping member 32. The upper clamping member 33 and the lower clamping member 32 are transmission-connected to the outside of the lower mold 35. During the wire crimping operation, the upper mold 36 moves upward through the driving device, and the terminal will enter the lower clamping member 32 through the guide groove. The lower clamping member 32 and the upper clamping member 33 are respectively provided with half a conical groove. The terminal enters the conical groove, and the propulsion component 2 aligns the end of the terminal with the surface of the conical groove. Then the moving member 34 drives the upper clamping member 33 to move downward to clamp the terminal. After clamping, the wire is input along the hole of the terminal through the robot. After the wire is inserted, the upper mold 36 moves downward under the drive of the driving device, and the wire and the terminal are crimped together through the lower mold 35 and the upper mold 36.

[0048] In a specific embodiment, a plurality of rectangular slots are formed in the feeding channel 6. Terminals of different styles are transported through the plurality of rectangular slots.

[0049] In a specific embodiment, the feeding component 7 is a vibrating plate, which vibrates to cause the terminal to spiral upward for feeding.
