Description

Technical Field

[0001] This utility model relates to the field of side airbag connector mating detection technology, and specifically to a side airbag connector mating detection device. Background Technology

[0002] like Figure 1 As shown, the side airbag 200 includes a covering layer and a gas generator and air bag disposed within the covering layer. The connector 201 of the side airbag 200 also needs to be connected to the wiring harness 300.

[0003] The existing side airbag connector insertion detection device 100 usually uses a cylinder to drive the wiring harness 300 directly into the connector 201 on the side airbag 200. However, since the wiring harness 300 itself is relatively fragile, the existing method of directly inserting the wiring harness 300 by driving it with a cylinder can easily result in excessive insertion force, which can easily damage the wiring harness 300 and thus affect the insertion effect. Utility Model Content

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a side airbag connector insertion detection device, comprising:

[0005] A carrier frame for placing side airbags;

[0006] A plug-in assembly includes a telescopic cylinder and a connecting frame connected to the output end of the telescopic cylinder. The connecting frame is provided with a slide rail, a support block, and a plug-in block. The plug-in block is provided with a connecting rod passing through the support block. A compression spring is sleeved on the connecting rod. The two ends of the compression spring press against the support block and the plug-in block respectively. The plug-in block is slidably mounted on the slide rail through the compression spring. A connector is provided on the plug-in block. The plug-in block is elastically connected to the plug-in rod through the connector. The telescopic cylinder is used to drive the plug-in rod to push the wire harness plug-in.

[0007] A displacement sensor is disposed on the plug-in block, and the detection end of the displacement sensor corresponds to the plug-in rod. The displacement sensor is used to detect whether the wire harness is plugged in properly.

[0008] Furthermore, the connector includes a compression spring two sleeved on the plug rod and a supporting part disposed on the plug rod. The plug block is provided with a sliding groove. The two ends of the compression spring two are respectively pressed between the supporting part and the sliding groove. The plug rod is slidably disposed in the sliding groove by means of the compression spring two.

[0009] Furthermore, the carrier is provided with a limiting component, which includes a limiting cylinder and a first clamping plate rotatably connected to the output end of the limiting cylinder. The carrier is provided with a second clamping plate corresponding to the first clamping plate. The limiting cylinder is used to drive the first clamping plate to move to the joint of the side airbag that is clamped by the second clamping plate.

[0010] Furthermore, both the first clamping plate and the second clamping plate are provided with clamping grooves that fit with the connector of the side airbag, and the clamping grooves are arc-shaped grooves.

[0011] Furthermore, a support plate is connected to the carrier, and a limit plate is rotatably connected to the support plate. The limit plate and the first clamping plate are rotatably connected.

[0012] Furthermore, it also includes a pressing assembly, which includes a pressing cylinder and a pressing plate connected to the output end of the pressing cylinder. The pressing cylinder is used to drive the pressing plate to move to press the side airbag.

[0013] Furthermore, it also includes a movable cylinder and a lifting cylinder disposed at the output end of the movable cylinder. The output end of the lifting cylinder is provided with a support frame for placing the pressing cylinder. The movable cylinder is used to cooperate with the lifting cylinder to drive the pressing cylinder to move.

[0014] Furthermore, the carrier is also equipped with a photoelectric sensor, which is used to detect the thickness of the surface of the covering layer of the side airbag, and the detection end of the photoelectric sensor faces the side airbag.

[0015] The beneficial effects of this utility model are as follows: By setting up the connecting rod and the first compression spring, when the telescopic cylinder drives the plug-in block to push the plug-in rod to insert the wire harness, the plug-in rod is subjected to the reaction force of the wire harness, which causes the first compression spring to compress. The first compression spring generates a reverse elastic force to offset part of the pushing force applied by the plug-in rod to the wire harness. Thus, when the force of the telescopic cylinder driving the plug-in rod to insert is too large, the pushing force on the wire harness is partially offset by the elastic force generated by the first compression spring, reducing the damage to the wire harness caused by excessive insertion force, thereby improving the insertion effect.

[0025] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Please refer to Figure 2 This utility model provides a side airbag connector insertion detection device 100, including a carrier 10, a insertion assembly 20 and a displacement sensor 30. The carrier 10 is used to place the side airbag 200.

[0027] Please refer to Figure 5 , Figure 6 and Figure 7The plug-in assembly 20 includes a telescopic cylinder 21 and a connecting frame 22 connected to the output end of the telescopic cylinder 21. The connecting frame 22 is provided with a slide rail 221, a support block 222, and a plug-in block 223. The plug-in block 223 is provided with a connecting rod 2231 passing through the support block 222. A compression spring 2232 is sleeved on the connecting rod 2231. The two ends of the compression spring 2232 press against the support block 222 and the plug-in block 223, respectively. The plug-in block 223 is slidably disposed on the slide rail 221 through the compression spring 2232. The plug-in block 223 is provided with a connector, and the plug-in rod 2233 is elastically connected to the plug-in block 223 through the connector. The telescopic cylinder 21 is used to drive the plug-in rod 2233 to push the wire harness 300 to plug in.

[0028] In order to reduce the space occupied by the plug-in assembly 20, the plug-in block 223 is provided with a groove 2234 for accommodating the support block 222, and the compression spring 2232 and the connecting rod 2231 are both located in the groove 2234.

[0029] By using the connecting rod 2231 and the compression spring 2232, when the telescopic cylinder 21 drives the plug block 223 to push the plug rod 2233 to insert the wire harness 300, the plug rod 2233 is subjected to the reaction force of the wire harness 300, which causes the compression spring 2232 to compress. The compression spring 2232 generates a reverse elastic force to offset part of the pushing force exerted by the plug rod 2233 on the wire harness 300. Thus, when the force of the telescopic cylinder 21 driving the plug rod 2233 to insert is too large, the pushing force on the wire harness 300 is partially offset by the elastic force generated by the compression spring 2232, reducing the damage to the wire harness 300 caused by excessive insertion force, thereby improving the insertion effect.

[0030] Please refer to Figure 5 The displacement sensor 30 is mounted on the plug-in block 223, and the detection end of the displacement sensor 30 corresponds to the plug-in rod 2233. The displacement sensor 30 is used to detect whether the wire harness 300 is plugged in properly. Specifically, the displacement sensor 30 in this embodiment is a contact displacement sensor 30, model GT-H22, purchased from Keyence (China) Co., Ltd. The model of the displacement sensor 30 is not limited to this; any displacement sensor 30 capable of displacement detection can be used in the technical solution of this application.

[0031] Please refer to Figure 5 , Figure 6 and Figure 7The connector includes a compression spring 2235 sleeved on the plug rod 2233 and a supporting part 2236 disposed on the plug rod 2233. The plug block 223 is provided with a sliding groove 2237. The two ends of the compression spring 2235 are respectively pressed between the supporting part 2236 and the sliding groove 2237. The plug rod 2233 is slidably disposed in the sliding groove 2237 through the compression spring 2235. When the telescopic cylinder 21 drives the plug rod 2233 to plug into the wire harness 300, the plug block 223 drives the plug rod 2233 to push the wire harness 300 to complete the plugging. After the plug rod 2233 is plugged into the wire harness 300, it slides relative to the plug block 223 under the reaction force of the wire harness 300, and pushes the compression spring 2235 to compress. The displacement sensor 30 detects the displacement of the plug rod 2233 relative to the plug block 223 at this time. If the displacement of the plug rod 2233 relative to the plug block 223 matches the expected displacement, then the wire harness 300 is properly plugged in. If the displacement of the plug rod 2233 relative to the plug block 223 does not match the expected displacement, then the wire harness 300 is not properly plugged in, and the wire harness 300 needs to be unplugged and replugged. After the test is completed, the telescopic cylinder 21 drives the plug block 223 to move the plug rod 2233 away from the wire harness 300, and the elastic force generated by the compression of the compression spring 2235 causes the plug rod 2233 to return to its original position relative to the plug block 223.

[0032] Please refer to Figure 2 and Figure 3 The carrier 10 is equipped with a limiting component 40, which includes a limiting cylinder 41 and a first clamping plate 42 rotatably connected to the output end of the limiting cylinder 41. The carrier 10 is equipped with a second clamping plate 11 corresponding to the first clamping plate 42. The limiting cylinder 41 is used to drive the first clamping plate 42 to move to cooperate with the second clamping plate 11 to clamp the connector 201 of the side airbag 200. Specifically, both the first clamping plate 42 and the second clamping plate 11 have clamping grooves 421 that fit with the connector 201 of the side airbag 200. The clamping grooves 421 are arc-shaped grooves. By setting the limiting component 40, the connector 201 of the side airbag 200 is limited during the insertion process, so that the connector 201 of the side airbag 200 is not easy to shake during insertion, thereby improving the stability of the insertion.

[0033] Please refer to Figure 3 A support plate 12 is connected to the carrier 10, and a limit plate 121 is rotatably connected to the support plate 12. The limit plate 121 is rotatably connected to the first clamping plate 42. The limit plate 121 restricts the rotation range of the first clamping plate 42.

[0034] Please refer to Figure 2 and Figure 4In this embodiment, the covering layer of the side airbag 200 is made of flexible material. Since the thickness of the airbag after folding is higher than the predetermined thickness, the surface of the covering layer is uneven and not easy to store. Therefore, the side airbag connector insertion detection device 100 also includes a pressing component 50 for flattening the surface of the side airbag 200. The pressing component 50 includes a pressing cylinder 51 and a pressing plate 52 connected to the output end of the pressing cylinder 51. The pressing cylinder 51 is used to drive the pressing plate 52 to move to press the side airbag 200.

[0035] Please refer to Figure 2 and Figure 3 The carrier 10 is also equipped with a photoelectric sensor 13, which is used to detect the thickness of the covering layer surface of the side airbag 200. The detection end of the photoelectric sensor 13 faces the side airbag 200, and the height of the photoelectric sensor 13 corresponds to the expected height position of the highest point on the surface of the side airbag 200.

[0036] Please refer to Figure 2 and Figure 4 The side airbag connector insertion detection device 100 also includes a movable cylinder 60 and a lifting cylinder 61 disposed at the output end of the movable cylinder 60. The output end of the lifting cylinder 61 is provided with a support frame 611 for placing the pressing cylinder 51. The movable cylinder 60 is used to cooperate with the lifting cylinder 61 to drive the pressing cylinder 51 to move. Through the cooperation of the movable cylinder 60 and the lifting cylinder 61, the pressing cylinder 51 can be moved to correspond with the side airbag 200 on the carrier 10.
