Description

Technical Field

[0001] The present application relates to the technical field of automotive sun visor detection devices, and more particularly to a test bench for detecting connectors of automotive sun visors. Background Art

[0002] An automotive sun visor is a baffle installed above the driver's seat of a vehicle to block sunlight. The automotive sun visor is rotatably connected to the vehicle body and can be horizontally hidden above the vehicle body under normal conditions. When in use, the automotive sun visor can be flipped down to block sunlight. Most existing automotive sun visors are provided with a vanity mirror and a lighting lamp for illuminating the vanity mirror area. To supply power to the lighting lamp, the wire of the lighting lamp passes through the base of the sun visor and is led out, and abuts and conducts with the pins on the connector, providing a prerequisite for supplying power to the lighting lamp by clamping the connector to the interface on the vehicle body.

[0003] Our company currently has an automotive sun visor, as Figure 1 shown. The automotive sun visor includes a sun visor body 90, a base 91, and a connector 92. The base 91 is provided on one side of the sun visor body 90. The connector 92 is electrically connected to the components inside the sun visor body 90 through a cable. More specifically, as Figure 2 shown, the connector 92 includes a housing 921 and two pins 922. The housing 921 has an interface cavity 9211 with an opening. The two pins 922 are arranged at intervals and are placed inside the interface cavity 9211 and are clamped to the housing 921. And the end of the pin 922 facing away from the opening of the interface cavity 9211 abuts against the copper wire inside the cable. It should be noted that before leaving the factory, it is necessary to detect whether the pin 922 is firmly clamped on the housing 921, whether its position is deviated, and whether the pin 922 is in good contact with the copper wire and can conduct. Currently, when detecting whether the pin 922 is firm and its position size, it is mostly detected manually, and the detection results are greatly affected by personal experience and state, and it is not easy to ensure the continuity and stability of the detection.

[0004] Therefore, there is a need to provide a test bench for detecting connectors of automotive sun visors with a relatively high degree of automation, which helps to improve the detection efficiency, stability, and continuity. Summary of the Invention

[0032] A test bench schematically for detecting the connector of an automotive sun visor

[0033] Referring to Figures 3 to 6 , a test bench for detecting the connector of an automotive sun visor according to a preferred embodiment of the present invention is used to test as Figure 2The connector 92 on the automobile sun visor shown in the figure comprises a shell 921 and two pins 922, the shell 921 has an interface cavity 9211 with an opening, the two pins 922 are arranged at intervals and placed in the interface cavity 9211 and snap-fitted to the shell 921, and the end of the pin 922 facing away from the opening of the interface cavity 9211 abuts against the copper wire on the automobile sun visor.

[0034] Furthermore, if Figure 3 As shown, the test bench for detecting automobile sun visor connectors includes a base 10, a detachment detection device 20 for testing whether the two pins 922 are firmly clamped on the shell 921, a positioning device 30 for testing whether the positions of the two pins 922 are offset, a power-on detection device 40 for testing whether the pins 922 are in contact with the copper wire and are conductive, and a placement table 50 for placing the automobile sun visor, the placement table 50 is slidably set on the base 10 and selectively makes the interface cavity 9211 face the detachment detection device 20 or the positioning device 30 or the power-on detection device 40.

[0035] It should be noted that in the embodiments of the present application, Figure 3 As shown, the positioning device 30 is located between the detachment detection device 20 and the power-on detection device 40 , and the placement platform 50 is reciprocatingly slidably disposed on the base 10 between the detachment detection device 20 and the power-on detection device 40 .

[0036] Specifically, in order to realize that the placing table 50 is slidably arranged on the base 10, as shown in FIG. Figure 3 As shown, the test bench for detecting automobile sun visor connectors also includes a rotation drive device 501, a threaded rod 502 and a plurality of guide rods 503, the guide rods 503 are fixedly connected to the base 10 and pass through the placement table 50, the rotation drive device 501 is fixedly installed on the base 10, and the rotating shaft of the rotation drive device 501 is fixedly connected to the threaded rod 502, the end of the threaded rod 502 facing away from the rotation drive device 501 is rotatably installed on the base 10, and the threaded rod 502 is threadedly connected to the placement table 50.

[0037] It should be noted that the rotation driving device 501 is further implemented as a rotary motor. The number of the guide rods 503 is two. The two guide rods 503 are located on both sides of the placement table 50. The lead screw 502 is located between the two guide rods 503. When the rotating shaft of the rotation driving device 501 rotates, the lead screw 502 rotates and drives the placement table 50 to reciprocate along the guide rods 503 in the length direction of the base 10. The length of the threaded part of the lead screw 502 and the length of the guide rods 503 are both greater than the distance between the detection and disconnection device 20 and the detection and energization device 40.

[0038] In addition, as Figure 3 shown, the top surface of the placement table 50 has a groove 504 and an extension part 505. The groove 504 has a notch 5041 on the side close to the detection and disconnection device 20. The extension part 505 has a clamping seat 5051. When an external automotive sun visor to be detected is placed on the placement table 50, the body of the automotive sun visor is placed in the groove 504, the cable of the automotive sun visor passes through the notch 5041, and the connector 92 is placed in the through groove of the clamping seat 5051. It should be noted that when the connector 92 is placed on the clamping seat 5051, the orifice of the interface cavity 9211 of the connector 92 faces away from the groove 504.

[0039] It should be noted that after the connector 92 is placed in the groove 504, by operating the rotation driving device 501, the interface cavity 9211 is aligned with the detection and disconnection device 20. Then the detection and disconnection device 20 extends into the interface cavity 9211 and applies a pressure to the two pins 922. If the pins 922 do not displace or only have a slight displacement under this specified pressure, the fastening test of the pins 922 is qualified. If the displacement distance of the pins 922 is greater than the predetermined size under this specified pressure or even the pins 922 come out of the housing 921, the fastening test of the pins 922 fails and it is a defective product.

[0040] In addition, after the fastening test of the pins 922, the positioning device 30 extends into the interface cavity 9211 and engages with the two pins 922. If the positioning device 30 can engage with the pins 922, it proves that the position dimensions of the two pins 922 are qualified. If the positioning device 30 is blocked by the pins 922 and cannot engage, at least one of the position dimensions of the pins 922 is unqualified and it is a defective product.

[0041] In addition, after the position and dimension of the pin 922 are tested, the pin 922 is tested for electrical connection by the power-on testing device 40, that is, the live power cord is joined to the pin 922. If it can conduct electricity normally, it is a qualified product. If it cannot conduct electricity normally after being powered on, such as the lighting lamp cannot light up normally after the lens cover is opened, it means that the contact between the pin 922 and the copper wire in the cable is poor, and it is a defective product.

[0042] When the connector 92 of the sun visor being tested passes the above three tests, a qualified product is obtained. Otherwise, it is a defective product waiting to be processed. Obviously, compared with the prior art, in the embodiment of the present application, by providing the detachment testing device 20, the position testing device 30, and the power-on testing device 40, the tightness, position and dimension, and contact with the copper wire of the pin 922 on the connector 92 are all detected. Compared with the prior art where it is still necessary to manually clamp and pull the pin 922 with a fixture to judge its tightness, manually insert the plug mold into the interface cavity 9211 to see if it fits with the pin 922, and separately test the electrical connection between the pin 922 and the copper wire on a single work station to check if the contact is good, the embodiment of the present application has the advantages of a higher degree of automation, which helps to improve the detection efficiency, stability, and continuity.

[0043] Further, in the embodiment of the present application, as Figure 4 shown, the detachment testing device 20 includes a first linear driving device 201, a support seat 202, two abutting members 203, two first elastic members 204, and two proximity switches 205. The first linear driving device 201 is installed on the base 10. The support seat 202 is fixedly connected to the push rod of the first linear driving device 201. The two abutting members 203 are slidably arranged on the support seat 202. A first elastic member 204 is connected between each abutting member 203 and the push rod of the first linear driving device 201. The two proximity switches 205 are respectively arranged on the opposite sides of the two abutting members 203.

[0044] It should be noted that it is assumed that at this time the interface cavity 9211 is facing the detection and removal device 20, and the two pins 922 are respectively facing the two abutting members 203. By operating the first linear driving device 201, the two abutting members 203 move towards the interface cavity 9211. At a certain moment, the two abutting members 203 abut against the two pins 922. As the abutting members 203 further apply a predetermined value of pressure towards the pins 922, if the clamping and fastening force at the pins 922 is greater than this preset pressure, it should be noted that the elastic force of the two first elastic members 204 is less than this preset pressure, then the pins 922 remain stationary, the two first elastic members 204 are deformed by the force, and the two abutting members 203 are moved in a direction away from the pins 922. At a certain moment, the proximity switch 205 is triggered. When the proximity switch 205 collects the displacement signal from the abutting member 203, this signal is transmitted to an external controller, and the tester can know that the clamping and fastening forces of the two pins 922 are both within the standard values, and the clamping and fastening force tests of the two pins 922 are qualified. It should also be noted that if after the abutting member 203 abuts against the pin 922 and the abutting member 203 further applies a predetermined value of pressure towards the pin 922, and at this time the first elastic member 204 does not move the corresponding abutting member 203 in a direction away from the pin 922 and trigger the proximity switch 205, it means that the clamping and fastening force of the pin 922 is less than the elastic force when the first elastic member 204 is compressed to a predetermined position, that is, the first elastic member 204 has not been moved to the predetermined position, and the pin 922 has come out of the housing 921, then the clamping and fastening force test of the pin 922 is unqualified.

[0045] More specifically, as Figure 5 shown, each abutting member 203 includes a narrowing portion 2031, a protruding portion 2032, and an insertion portion 2033. The protruding portion 2032 is located between the narrowing portion 2031 and the insertion portion 2033. The width of the abutting member 203 at the protruding portion 2032 is greater than the width of the abutting member 203 at the narrowing portion 2031. When the first elastic member 204 is in an undeformed state, the proximity switch 205 faces the narrowing portion 2031. When the first elastic member 204 is deformed by the force and triggers the pin switch, the proximity switch 205 faces the protruding portion 2032. Since the technology of the proximity switch 205 is mature and it is widely used in the market, the specific structure and model of the proximity switch 205 will not be elaborated here. The proximity switch 205 includes, but is not limited to, the proximity switch 205 disclosed in the patent document (CN110880927A).

[0046] Furthermore, as Figure 4As shown, the positioning device 30 includes a second linear driving device 301, a first sliding seat 302, and a first insert 303. The second linear driving device 301 is fixedly installed on the base 10. The first sliding seat 302 is slidably disposed on the base 10, and the push rod of the second linear driving device 301 is fixedly connected to the first sliding seat 302. The first insert 303 is disposed on the first sliding seat 302. As Figure 6 shown, the end of the first insert 303 has two slots 3031.

[0047] It should be noted that assuming that the interface cavity 9211 is facing the positioning device 30 at this time, when the push rod of the second linear driving device 301 moves, the first sliding seat 302 moves accordingly, and the first insert 303 is inserted into the interface cavity 9211. If the height positions of the two pins 922 are within the rated dimensions, then as the first insert 303 further extends into the interface cavity 9211, the two pins 922 extend into the corresponding slots 3031. On the contrary, if the two pins 922 cannot extend into the corresponding slots 3031, that is, the first insert 303 is blocked by at least one of the pins 922, it indicates that the position dimensions of the pins 922 are unqualified.

[0048] Furthermore, to prevent the pins 922 from breaking when the first insert 303 is blocked by the pins 922, as Figure 4 shown, the first sliding seat 302 has a guide rail 3021. The positioning device 30 further includes a second sliding seat 304, a sliding rod 305, and a second elastic member 306. The second sliding seat 304 is slidably disposed on the guide rail 3021. The first insert 303 is fixedly installed at one end of the second sliding seat 304 close to the placement table 50. The sliding rod 305 is slidably disposed on the first sliding seat 302 and is fixedly connected to the end of the second sliding seat 304 away from the first insert 303. The second elastic member 306 is sleeved on the sliding rod 305, and both ends of the second elastic member 306 are abutted against the second sliding seat 304 and the first sliding seat 302 respectively.

[0049] It should be noted that when the first insert 303 is blocked by the pins 922, the second sliding seat 304 moves in a direction away from the pins 922, and the second elastic member 306 is compressed and deformed to provide an axial space to prevent the first insert 303 from bending the pins 922.

[0050] Furthermore, as Figure 4As shown in the figure, the power-on testing device 40 includes a third linear driving device 401, a second insert 402, and a base body 403. The third linear driving device 401 is fixedly installed on the base 10, and the push rod of the third linear driving device 401 is connected to the base body 403. The base body 403 has a through external wiring hole 4031. The second insert 402 is connected to the side of the base body 403 close to the placement table 50, and one end of the second insert 402 extends into the external wiring hole 4031 by a predetermined distance.

[0051] It should be noted that assuming that the interface cavity 9211 is directly opposite to the power-on testing device 40, an external power cord interface is inserted into the external wiring hole 4031. After the third linear driving device 401 operates, the external power cord interface is brought into contact with and conductively connected to the two pins 922. If current data can be measured or the lighting lamp lights up after the car sun visor mirror cover is opened, it proves that the pins 922 are in good contact with the copper wire; otherwise, it is a defective product.

[0052] Furthermore, as Figure 3 shown in the figure, the test bench for detecting the car sun visor connector further includes a pressing device 60 for pressing the connector. The pressing device 60 includes a lifting driving device and a pressing member (not marked in the figure). The lifting driving device is fixedly installed on the extension part 505 of the base 10. The pressing member is fixedly connected to the push rod of the lifting driving device, and the pressing member is located directly above the card seat 5051. During testing, the lifting driving device moves downward, and the pressing member presses the connector 92.

[0053] In summary, the test bench for detecting the car sun visor connector based on the embodiment of the present application is clarified. It provides advantages such as a relatively high degree of automation, which helps to improve the detection efficiency, stability, and continuity for the test bench for detecting the car sun visor connector.

[0054] It is worth mentioning that in the embodiment of the present application, the test bench for detecting the car sun visor connector has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economy. At the same time, for manufacturers, the test bench for detecting the car sun visor connector provided by the present application is easy to produce and has a low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
