Technical Field

[0001] The present invention relates to the field of machinery, and in particular to an error-proofing tool for inserting a wire into a connector. Background Art

[0002] At present, with the rapid development of the new energy vehicle industry, various electrical and electronic components and control systems need to be closely connected to provide users with a better experience. Among them, the wiring harness is equivalent to blood vessels. It must ensure the transmission of electrical signals, ensure the reliability of the connection circuit, supply the specified current value to the correct circuit, and prevent wrong paths.

[0003] Wire harness processing, particularly the wiring insertion process, relies heavily on manual labor. This leads to numerous errors during production, such as misplaced wire insertion. This leads to rework, wasted labor time, and potentially damaged parts. To prevent misplaced wire insertion, manual inspections or color sensors are often added for re-identification. These are post-processing technologies that fail to prevent problems beforehand, resulting in unnecessary waste and rework. This negatively impacts product quality and production efficiency.

[0022] Combine Figures 1 to 4 As shown in the content, the present invention discloses an anti-error tooling for inserting a wire into a connector, including a base 1, a fixing seat 7 is provided on the base 1, a contoured cavity for placing a connector 10 is opened on the fixing seat 7, a baffle mechanism is provided on one side of the contoured cavity, the baffle mechanism is arranged corresponding to the wire insertion hole on the connector 10 for connecting the wire 9, a sensor 11 is provided above the contoured cavity, and the sensor 11 is used to identify the wire 9.

[0023] A sensor fixing mechanism is provided on the base 1, and the sensor fixing mechanism includes a bracket 15 and a positioning block 12. The bottom of the bracket 15 is connected to the base 1, and the positioning block 12 is connected to the upper end of the bracket 15. The positioning block 12 is connected to the sensor 11, wherein the bottom of the positioning block 12 is provided with a groove for accommodating the sensor 11, and the positioning block 12 is provided with through holes around the groove. Connecting holes are provided on the sensor 11 corresponding to the through holes. The sensor 11 and the positioning block 12 are locked and fixed by screws inserted into the through holes and the connecting holes in sequence.

[0024] In some specific implementations, the bracket 15 and the positioning block 12, as well as the positioning block 12 and the sensor 11, are both detachably connected, for example:

[0025] A fixing rod 13 is provided on one side of the bracket 15, and the positioning block 12 is sleeved on the fixing rod 13, and the end of the fixing rod 13 away from the bracket 15 passes through the positioning block 12, and a rod sleeve 14 is provided on the fixing rod 13 passing through the positioning block 12, and the positioning block 12 is locked by the rod sleeve 14.

[0026] In some specific implementations, the bracket 15 is connected to the positioning block 12 via a position adjustment device, and the position adjustment device and the positioning block 12, as well as the positioning block 12 and the sensor 11, are both detachably connected.

[0027] The position adjustment device includes a vertical mechanism and / or a horizontal mechanism,

[0028] The vertical mechanism is used to control the distance between the sensor 11 and the base 1 in the vertical direction;

[0029] The horizontal mechanism is used to adjust the horizontal position of the sensor 11;

[0030] The vertical mechanism, horizontal mechanism, connection structure between the adjustment device and the positioning block 12, and connection structure between the positioning block 12 and the sensor 11 can all be directly implemented using existing technologies, and therefore will not be described in detail here.

[0031] It should be noted that the sensor 11 is a visual sensor, which recognizes the color of the wire 9 through the visual sensor.

[0032] The fixing base 7 is also provided with a locking device for fixing the connector 10. For example, a cylinder 8 connected to the air pump is provided on the fixing base 7. The air pump and the cylinder 8 can also be replaced by other existing telescopic components. An opening is provided on one side of the wire insertion hole of the connector 10 on the fixing base 7, and one end of the cylinder 8 is embedded in the side wall on the side of the opening.

[0033] The baffle mechanism includes a baffle positioning block 4 arranged on the base 1, a telescopic member group arranged on the baffle positioning block 4, a baffle 5 arranged corresponding to the telescopic member group, and a contact switch 6. The telescopic member group includes multiple telescopic members 3, the telescopic member 3 is connected to the contact switch 6, each telescopic member is provided with a baffle 5, the baffle 5 corresponds to the wire insertion hole of the connector 10, a connecting rod is provided on the baffle positioning block 4 to connect the contact switch 6, and the contact switch 6 passes through the fixed seat 7 to the profiling mold cavity (the contact switch 6 can also be directly arranged on the hole wall of the profiling mold cavity), and the contact switch 6 is connected to the cylinder 8. When the connector 10 is placed into the profiling mold cavity, the connector 10 touches the contact switch 6, and the cylinder 8 extends the telescopic rod on the cylinder 8 from the side to lock the connector 10 (at this time, the connector 10 is placed between the telescopic rod and the hole wall of the profiling mold cavity). At the same time, under the action of the telescopic member, the baffle 5 is controlled to rise, so as to achieve the purpose of using the baffle 5 to cover the wire insertion hole on the connector 10. The telescopic device 3 described herein can directly adopt any one of the existing electric, pneumatic and hydraulic controlled telescopic devices.

[0034] A plurality of through holes are provided on the fixing base 7 at an opening on one side of the wire insertion hole of the connector 10 , corresponding to the wire insertion hole, and the through holes correspond to the baffle 5 one by one.

[0035] The error-proofing tool for inserting a wire into the connector further includes a button 2 , which can be directly mounted on the base 1 . The button 2 is used to control the working state of the entire error-proofing tool for inserting a wire into the connector.

[0036] Taking a connector 10 with three wire insertion holes corresponding to three wires 9 of different colors, and a baffle mechanism with three telescopic members 3 and three baffles 5 as an example, the working principle of the error-proofing tooling for inserting wires into the connector is as follows:

[0037] Take a wire and place it under the sensor. The sensor identifies the wire color and sends a signal to control one of the three baffles 5 to drop, exposing the corresponding wire insertion hole on the connector. The employee can then insert the wire into this exposed wire insertion hole. Repeat the process of taking the wire → sensor identification → baffle drop → inserting the wire until all three wires of different colors are inserted into the connector. The sensor automatically identifies that the connector has been inserted and sends a signal to control the cylinder 8 to open and lock. At this time, the plugged-in connector can be taken out and wait for the next product to be produced. The sensor identification and related automated control procedures involved can be directly implemented using existing technologies, so they will not be described in detail here.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several similar variations and improvements without departing from the creative concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
