Description

Technical Field

[0001] The present invention relates to the field of terminals, and more particularly to a jet-type high-speed oiling and testing device for PCB female terminals. Background Art

[0002] At present, the domestic PCB terminal oiling method is mostly immersion oiling, which is uneven and most of the terminal interiors cannot be oiled. The existing jet oiling equipment abroad is slow, with a speed of 5 terminals per second, which seriously affects efficiency.

[0003] With the continued growth of the automotive market, the demand for relay boxes is also increasing, and the demand for and quality of PCB terminals are also getting higher and higher. If there is a deviation in the terminal positioning, the relative position of the nozzle and the terminal will change, which will lead to uneven oiling or omissions. At the same time, the surface roughness and contamination degree of terminals in different batches may be different, which will affect the formation of the oil film. Summary of the Invention

[0046] It should be supplemented that the outer wall of the circulation assembly 340 is covered with a cover plate 370 to prevent the terminal oil sprayed from the oil injection nozzle 360 ​​from splashing into the interior of the circulation assembly 340 .

[0047] In one embodiment of the present invention, the cleaning assembly 500 includes a sand box 510, a cleaning chamber 520, and a connecting air nozzle 530. The cleaning chamber 520 is provided on the top outer wall of the sand box 510, and the connecting air nozzle 530 is installed on the bottom outer wall of the sand box 510.

The PCB female terminal body 200 is cleaned in the cleaning area. After cleaning, the terminal surface of the PCB female terminal body 200 can be better cleaned, and the surface of the terminal is processed to have a surface structure with a certain degree of roughness.

[0048] The blowing assembly 700 includes a blower, an oil tank and a filter. The filter is installed in the inner wall of the bottom end of the oil tank. The filter is connected to an oil pump, which is connected to the circulation assembly 340 through an oil pipe.

[0049] In one embodiment of the present invention, Figure 7As shown, a detection device is provided at both ends of a conveying assembly 100, namely a front detection assembly 400 and a rear detection assembly 600. The detection ends of the front detection assembly 400 and the rear detection assembly 600 can be on different sides or the same side. The front detection assembly 400 and the rear detection assembly 600 both include a detection bracket 410, a telescopic rod group 420, a CCD and a lens holder 440. The telescopic rod group 420 is mounted on the detection bracket 410, and the CCD 430 and the lens holder 440 are both mounted on the telescopic rod group 420. A magnifying lens is provided in the lens holder 440. The CCD 430 is used to visually monitor the PCB female terminal body 200 after oil injection.

[0050] It should be noted that the telescopic rod assembly 420 includes at least two groups of telescopic rods, and the ends of the telescopic rods are provided with supports, and the CCD 430 and the lens holder 440 are both mounted on the supports;

[0051] It should be noted that the front detection component 400 and the rear detection component 600 are connected to the same comparison system, which is used to process the collected images of the PCB female terminal body 200 before and after oil injection;

[0052] It should also be noted that a phase-collecting port is provided on the outer wall of the sliding track 150 close to the detection assembly, and the phase-collecting port is facing the PCB female terminal body 200 on the workstation;

[0053] In one embodiment of the present invention, the PCB female terminal body 200 is oiled by spraying oil. The oiling process includes the following steps:

[0054] The oiling device is installed in a terminal production line. The PCB female terminal body 200 moves step by step along the sliding track 150 in the conveying assembly 100. The movement is achieved by a stepping component.

[0055] During the stepping component conveying process, a positioning sensor 120 is provided at each station. The positioning sensor 120 is used to position the PCB female terminal body 200 after each step, and at the same time, the elastic member is used to correct the deviation of the PCB female terminal body 200.

[0056] When the PCB female terminal body 200 moves to the cleaning area, the open end of the PCB female terminal body 200 extends into the cleaning chamber 520, and the surface is sandblasted by circulating diamond abrasives. Four PCB female terminal bodies 200 are sandblasted once in a group.

[0057] Then step to the work station where the oil spray component 300 is located, and the oil spray component 300 sprays oil on the PCB female terminal body 200. The oil spraying process is as follows: the three-axis moving seat 320 drives the pneumatic clamp 330 and the PCB female terminal body 200 clamped by it to move back and forth along the axis of the circulation component 340, and the terminal oil is sprayed out through the oil nozzle 360 ​​in the oil spray component 300 for spraying. During the spraying process, the pull rod 350 is driven to rotate by the telescopic cylinder 380, and the pull rod 350 drives the opening and closing block 342 to move together along the radial direction, driving the oil spraying distance of the oil spray nozzle 360 ​​to change. The oil can be sprayed at a close distance first, and then the PCB female terminal body 200 after the oil spraying can be continuously sprayed at a long distance. The close-range spraying is used to control the rapid wetting and bonding of the coating with the substrate, and the long-distance spraying is used for comprehensive coverage to avoid local accumulation and sagging.

[0058] At the same time, during spraying, the pneumatic clamp 330 is driven to rotate circumferentially through the circumferential rotating seat to cooperate with the oil spraying assembly 300 to spray;

[0059] After spraying, it enters the blowing area, which evenly distributes the terminal oil on the surface to reduce the dripping of the terminal oil on the surface, and at the same time, the terminal oil is stably attached to the PCB female terminal body 200;

[0060] Then it is transported to the rear inspection component 600 station, where it is imaged by the CCD 430. Similarly, when it is input to the front end of the sliding track 150, the CCD 430 in the front inspection component 400 captures the image of the PCB female terminal body 200 that has not been sprayed with oil. The two captured images of the PCB female terminal body 200 before and after the oil spraying are compared to ensure that the terminal size of the PCB female terminal body 200 is consistent and the oil coating state meets the qualified standards.

[0061] This equipment uses multiple nozzles in the circulation component 340 for annular oiling and coordinates spraying at long and short distances, which can greatly improve production efficiency from the original 1s / 5pcs to 1s / 10pcs. The stability of oiling and quality inspection are also improved through detection equipment.

[0062] The above describes the embodiments of this embodiment, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
