Description

Technical Field

[0001] This application relates to the technical field of finished product testing of automotive parts, and in particular to a general-purpose testing device for split armrests. Background Technology

[0002] As the automotive industry matures, consumers are demanding higher and higher levels of functionality and quality from car features.

[0003] However, in the traditional production process of automotive parts, such as the armrest box cover of a car, the functional testing of finished products before leaving the factory is mostly based on the subjective judgment of the quality supervisor, and there are no specific quantitative data standards for whether the product is qualified.

[0004] Moreover, everyone's subjective feelings are different, which leads to significant differences in details of different aspects of products, even if they are the same overall, resulting in a rather poor experience for car consumers. Utility Model Content

[0005] In order to standardize the testing process for armrest box covers and obtain qualified products with high quality consistency, this application provides a universal double-opening armrest testing device.

[0006] The general-purpose double-leaf handrail testing device provided in this application adopts the following technical solution: A general-purpose double-leaf handrail testing device includes: a frame, a PLC controller, and a testing platform mounted on the frame; The detection platform is equipped with a positioning component and a detection component. The positioning component is used to position the armrest box cover, and the detection component is used to press the armrest box cover's door switch to test the opening force of the two doors. Laser sensors are installed on both sides of the positioning component. The laser sensors are used to test the change in distance between the two doors of the armrest box cover and the laser sensors before and after opening. Both the detection component and the laser sensors are electrically connected to a PLC controller. The PLC controller's built-in algorithm can calculate data such as the final opening angle of the armrest box cover, the angle difference between the two sides, the time required for the entire opening process, and the synchronicity of the opening of the two sides based on the data transmitted by the detection component and the laser sensors.

[0007] By adopting the above technical solution, the position of the armrest box cover is defined by the positioning component. Then, the laser sensor and detection component are activated. As the detection component presses the armrest box cover switch, both covers of the armrest box cover open simultaneously. The detection component transmits the opening force data of the armrest box cover to the PLC controller. The laser sensor senses the change in distance between the two covers and the laser sensor when they open, as well as the time difference between the two covers, and transmits this data to the PLC controller. Through internal algorithms, the final opening angle of the armrest box cover, the angle difference between the two sides, the time required for the entire opening process, and the synchronicity of the opening on both sides are calculated. The actual data is compared with the requirements to automatically determine whether the product is qualified, thereby standardizing the inspection process of the armrest box cover and obtaining qualified products with high quality consistency.

[0008] Optionally, the detection component includes a servo module and a pressure sensor mounted on the servo module. The servo module is mounted on the detection platform and is used to drive the pressure sensor to move up and down. The pressure sensor is located directly above the door switch button on the armrest box lid placed on the positioning component.

[0009] Optionally, the positioning component includes a first limiting member, a second limiting member, and a locking member installed on the detection platform; The first limiting member has two sets arranged horizontally opposite each other. The first limiting member abuts against the side wall of the armrest box cover. The second limiting member is located between the two sets of first limiting members and there are several of them. The several second limiting members are engaged with the side wall and bottom of the armrest box cover. The locking member is located on one side of the first limiting member and is engaged with the side wall of the armrest box cover.

[0010] Optionally, the first limiting component includes a plurality of positioning pins, which are vertically installed on the detection platform and spaced apart along the arrangement direction perpendicular to the two sets of first limiting components. The top of each positioning pin is provided with a guide slope, which is inclined from bottom to top along the direction close to the axis of the positioning pin.

[0011] Optionally, the second limiting member includes a first positioning block and a second positioning block. The top of the first positioning block is provided with a positioning groove for engaging with the corner of the armrest box cover, and the top of the second positioning block is provided with a positioning post for engaging with the bottom of the armrest box cover.

[0012] Optionally, the locking component includes a locking cylinder and a locking rod. The locking cylinder is installed on the testing platform, the locking rod is horizontally arranged and one end is coaxially connected to the output shaft of the locking cylinder, and the other end of the locking rod is inserted into and abuts against the mounting hole on the side wall of the armrest box cover.

[0013] Optionally, two laser sensors are horizontally arranged along the opening direction of the armrest box cover, and the height of the two laser sensors is between the height of the armrest box cover when it is closed and the height when it is open.

[0014] In summary, this application includes at least one of the following beneficial technical effects of a general-purpose double-handrail detection device: The armrest box lid to be inspected is placed on the inspection platform. The position of the armrest box lid is defined by the positioning component. The laser sensor and the detection component are activated. The detection component presses the lid switch of the armrest box lid, and both lids open simultaneously. The detection component transmits the opening force data of the armrest box lid to the PLC controller. The laser sensor senses the change in distance between the lid and the laser sensor when the armrest box lid opens, as well as the time difference between the two armrest box lids, and transmits the data to the PLC controller. Through internal algorithms, the final opening angle of the armrest box lid, the angle difference between the two sides, the time required for the entire opening process, and the synchronicity of the opening on both sides are calculated. The actual data is compared with the requirements to automatically determine whether the product is qualified, thereby standardizing the inspection process of the armrest box lid and obtaining qualified products with high quality consistency. By using the first limiting component, the second limiting component, and the locking component, not only is the armrest box cover limited in all directions, but the position of the armrest box cover when it is placed stably is also locked, simulating the state of the armrest box cover when it is inside the car, thus improving data accuracy.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] This application discloses a general-purpose testing device for split handrails. (Refer to...) Figure 1 and Figure 2 The system includes a frame 1, a PLC controller 2, and a testing platform 3 mounted on the frame 1. The testing platform 3 is equipped with a positioning component 4 and a testing component 5. The positioning component 4 is used to position the armrest cover 7, and the testing component 5 is used to press the door switch of the armrest cover 7 to test the opening force of the armrest cover 7. Laser sensors 6 are installed on both sides of the positioning component 4. The laser sensors 6 are used to test the change in distance between the two doors of the armrest cover 7 before and after opening and the laser sensors 6. Both the testing component 5 and the laser sensors 6 are electrically connected to the PLC controller 2.

[0023] like Figure 2 and Figure 3 As shown, the armrest box cover 7 is placed on the inspection platform 3, and its position is defined by the positioning component 4. Then, the laser sensor 6 and the inspection component 5 are activated. As the inspection component 5 presses the door switch of the armrest box cover 7, both doors of the armrest box cover 7 open simultaneously. The inspection component 5 transmits the opening force data of the armrest box cover 7 to the PLC controller 2. The laser sensor 6 senses the change in distance between itself and the armrest box cover 7 as the doors open, as well as the time difference between the changes in distance between the two doors, and transmits this data to the PLC controller 2. The built-in algorithm of the PLC controller 2 can calculate the final opening angle of the armrest box cover 7, the angle difference between the two sides, the time required for the entire opening process, and the synchronicity of the opening on both sides based on the data transmitted by the inspection component 5 and the laser sensor 6. By comparing the actual data with the requirements, the system automatically determines whether the product is qualified, thereby achieving a standardized inspection process for the armrest box cover 7 and obtaining qualified products with high quality consistency.

[0024] Reference Figure 2 and Figure 4The detection component 5 includes a servo module 51 and a pressure sensor 52 installed on the servo module 51. The servo module 51 is installed on the detection platform 3 and is used to drive the pressure sensor 52 to rise and fall. The pressure sensor 52 is located directly above the door switch button of the armrest box cover 7 placed on the positioning component 4.

[0025] Among them, such as Figure 4 and Figure 5 As shown, the servo module 51 drives the pressure sensor 52 to press down, simulating the opening state of a human hand pressing. Since it is driven by a servo motor, the pressing speed can be quantified and set. Furthermore, during the pressing process, the opening force of the armrest box cover 7 can be determined based on the change in force value of the pressure sensor 52. Both the servo module 51 and the pressure sensor 52 are electrically connected to the PLC controller 2 to facilitate the control of the servo motor and the transmission of data from the pressure sensor 52.

[0026] Reference Figure 2 and Figure 3 The positioning component 4 includes a first limiting member 41, a second limiting member 42, and a locking member 43 installed on the detection platform 3. The first limiting member 41 has two sets arranged horizontally opposite each other, and the first limiting member 41 abuts against the side wall of the armrest box cover 7. The second limiting member 42 is located between the two sets of first limiting members 41 and there are several of them. The several second limiting members 42 are engaged with the side wall and bottom of the armrest box cover 7. The locking member 43 is located on one side of the first limiting member 41 and is engaged with the side wall of the armrest box cover 7.

[0027] The first limiting member 41 includes several positioning pins 411. The positioning pins 411 are vertically installed on the detection platform 3 and are arranged at intervals along the arrangement direction perpendicular to the two sets of first limiting members 41. The top of the positioning pin 411 is provided with a guide slope 412. The guide slope 412 is arranged at an angle along the axis direction close to the positioning pin 411, so as to facilitate the quick placement of the armrest box cover 7 and guide the armrest box cover 7 to fall into the correct position.

[0028] In addition, the second limiting member 42 includes a first positioning block 421 and a second positioning block 422. The top of the first positioning block 421 is provided with a positioning groove 423 for engaging with the corner of the armrest box cover 7, and the top of the second positioning block 422 is provided with a positioning post 424 for engaging with the bottom of the armrest box cover 7.

[0029] The positioning pin 424 can be inserted into the mounting hole at the bottom of the armrest box cover 7. The mounting hole is pre-set during production to match the vehicle. This restricts the horizontal position of the armrest box cover 7. The positioning pin 424 is located between the positioning pins 411, thereby limiting the horizontal position of the armrest box cover 7 in all directions.

[0030] Furthermore, to more perfectly simulate the state of the armrest box cover 7 when installed on a car, the position of the armrest box cover 7 needs to be locked. For example... Figure 2 and Figure 5 As shown, the locking component 43 includes a locking cylinder 431 and a locking rod 432. The locking cylinder 431 is installed on the testing platform 3. The locking rod 432 is horizontally arranged and one end is coaxially connected to the output shaft of the locking cylinder 431. The other end of the locking rod 432 is inserted into and pressed against the mounting hole on the side wall of the armrest box cover 7. The mounting hole on the side wall of the armrest box cover 7 is set during production in order to match the car. The locking rod 432 is inserted into the mounting hole to better simulate the state when the armrest box cover 7 is installed on the car.

[0031] Reference Figure 4 and Figure 5 In order to more accurately measure the opening state of the armrest box cover 7, two laser sensors 6 are horizontally arranged along the opening direction of the two doors of the armrest box cover 7. The two laser sensors 6 correspond to the two doors of the armrest box cover 7, and the height of the two laser sensors 6 is between the height of the armrest box cover 7 when the doors are closed and the height when they are open, so as not to affect the measurement accuracy.

[0032] The implementation principle of a general-purpose double-leaf armrest detection device according to an embodiment of this application is as follows: Before detection, the armrest box cover 7 is placed on the detection platform 3, and the positioning pin 411, the first positioning block 421, and the second positioning block 422 are all engaged with the armrest box cover 7. Then, the locking rod 432 is inserted into the mounting hole to simulate the state of the armrest box cover 7 on a car. Subsequently, the pressure sensor 52 moves down to press the cover switch button of the armrest box cover 7, and the laser sensor 6 senses the position change of the two covers of the armrest box cover 7 opening simultaneously. As the two covers open, the pressure sensor 52 presses the cover of the armrest box cover 7. The opening force data is transmitted to the PLC controller 2. The laser sensor 6 senses the changes in distance between the two doors and the laser sensor 6 when the armrest box cover 7 is opened, as well as the time difference between the changes in distance between the two doors, and transmits the data to the PLC controller 2. Through internal algorithms, the final opening angle of the armrest box cover 7, the angle difference between the two sides, the time required for the entire opening process, and the synchronicity of the opening on both sides are calculated. The actual data is compared with the requirements to automatically determine whether the product is qualified, thereby standardizing the inspection process of the armrest box cover 7 and obtaining qualified products with high quality consistency.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
