Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to an automatic dotting device. Background Art

[0002] A wiring harness is a device used to transmit signals between electronic components in a car, facilitating the installation and maintenance of electronic components and ensuring the car can operate in harsh environments. In practice, the wiring harness is cut according to the different needs of the customer, and is dotted and marked before cutting. The existing wiring harness dotting process is as follows: the operator holds a dotting machine, moves the dotting machine directly above the wiring harness, and aligns the dotting end of the dotting machine with the position on the wiring harness that needs to be dotted, and then turns on the dotting machine to dot the wiring harness with the dotting end. This processing method has low work efficiency, poor accuracy, and high work intensity. Therefore, how to develop a new type of automatic dotting device to overcome the above-mentioned problems in the prior art is a research direction for those skilled in the art. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic marking device, which can improve the efficiency of cable marking processing, improve the accuracy of operation, and reduce the work intensity of staff.

[0004] The utility model discloses an automatic dotting device, which comprises:

[0005] A processing table, wherein the upper side of the processing table is provided with a plurality of mutually parallel wire troughs, and the wire troughs are used to place the wire harness to be processed;

[0006] A first thread end barrel, the first thread end barrel is fixedly mounted on one end of the processing table, and the first thread end barrel is used to fix one end of the wire harness to be processed;

[0007] A second thread end barrel, the second thread end barrel is fixedly mounted on the other end of the processing table, and the second thread end barrel is used to fix the other end of the wire harness to be processed;

[0008] Two X-axis ball screws, the two X-axis ball screws are symmetrically mounted on the fixed platform; the nut seats of the two X-axis ball screws are respectively fixedly connected to the Y-axis fixing seat and the Y-axis supporting seat;

[0009] A Y-axis ball screw, with both ends of the rod body of the Y-axis ball screw being respectively mounted on the Y-axis fixing seat and the Y-axis supporting seat;

[0010] A dotting machine, the dotting machine being fixedly connected to the nut seat of the Y-axis ball screw, and the dotting machine being configured to perform dotting processing on the wiring harness to be processed;

[0011] A controller is electrically connected to the dotting machine and is used to control the dotting machine.

[0012] By adopting this technical solution: the two ends of the multiple wire harnesses to be processed are respectively fixed in the first wire end barrel and the second wire end barrel in advance, and the middle sections of the multiple wire harnesses to be processed are respectively placed in the wire grooves, and the Y-axis ball screw is operated to rotate to drive the dotting machine to move to the wire harnesses aligned with each wire groove in sequence, and the controller is started to perform dotting through the dotting machine. During the process, since the dotting machine does not move in the x-axis direction when moving, the accuracy of the processing is improved. At the same time, continuous operation of multiple wire harnesses to be processed is also achieved, thereby improving processing efficiency. In addition, this solution can also switch the position of the dotting machine in the x-axis direction by synchronously operating the two X-axis ball screws, thereby meeting the dotting requirements for different wire harnesses.

[0013] Preferably, the dotting machine is provided with a dotting end and an elastic positioning component; the dotting end is used to dot the wire harness to be processed; the elastic positioning component is installed on both sides of the dotting end and is used to position the wire harness to be processed by the dotting end.

[0014] By adopting this technical solution: during the dotting process, the two sides of the wiring harness to be processed are positioned by the elastic positioning component, so that the wiring harness to be processed remains stable when the dotting end contacts the wiring harness to be processed.

[0015] Preferably, the elastic positioning assembly includes two springs, one end of the two springs is symmetrically installed at both ends of the dotting end; the other ends of the two springs are respectively fixedly connected to a material support, and the two material supports are respectively provided with facing metal slopes.

[0016] By adopting this technical solution: during the dotting process, the controller controls the dotting machine to start. At this time, the dotting end drives the two material supports to move synchronously toward the wire harness to be processed. The facing metal inclined surfaces of the two material supports contact the left and right sides of the upper side of the wire harness to be processed and press the wire harness to be processed. The spring is compressed until the dotting end contacts the wire harness to be processed to complete the dotting. Then the dotting end is reset, and then the spring is reset from the compressed state.

[0017] Preferably, the apparatus further comprises: a driving mechanism, wherein the driving mechanism is connected to the first thread barrel and the second thread barrel respectively, and the driving mechanism is configured to drive the first thread barrel and the second thread barrel to move closer to / away from each other.

[0018] By adopting this technical solution: by adjusting the distance between the first wire end barrel and the second wire end barrel, it is possible to achieve positioning and clamping of wire harnesses to be processed of different lengths.

[0019] Preferably, the driving mechanism comprises:

[0020] a first slide rail, the first slide rail being fixedly mounted on one end of the processing table, the first thread barrel being mounted with a first slider, the first slider being slidably mounted on the first slide rail;

[0025] A lifting cylinder is fixedly installed on the lower side of the processing table, and the movable end of the lifting cylinder is connected to the airbag.

[0026] By adopting this solution: when the distance between the first and second thread barrels is adjusted to increase, the lifting cylinder is activated, and its movable end is lifted upward to squeeze the airbag. Due to the squeezing of the airbags, the first and second telescopic airbag columns expand along the first and second sleeves respectively, synchronously pushing the first and second push rods to move in opposite directions, and then realizing the opposite movement between the first and second thread barrels through the first and second sliders. When the distance between the first and second thread barrels is adjusted to decrease, the lifting cylinder is activated, and its movable end is lowered to pull the airbag back to its original position. The first and second telescopic airbag columns are synchronously reset, driving the first and second thread barrels to move toward each other.

[0027] Preferably, a side baffle is further installed on the upper side of the processing table, and a placement gap is provided on the side baffle.

[0028] By adopting this technical solution: the spare parts needed in the processing process are temporarily placed in the placement gap.

[0049] It should be noted that, in the above solution, the ball screw is a mature existing technology, so its working principle will not be elaborated in this article. At the same time, the motor structure for providing power to each ball screw is omitted in the relevant figures.

[0050] In practice, the process works as follows:

[0051] The two ends of the plurality of wire harnesses to be processed are fixed in the first wire end barrel 210 and the second wire end barrel 220 respectively, and the middle sections of the plurality of wire harnesses to be processed are placed in the respective wire grooves 110 respectively.
