Technical Field

[0001] This application relates to the technical field of automotive parts manufacturing, and in particular to a universal cup holder testing device. Background Technology

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

[0003] In the traditional automotive parts manufacturing process, such as cup holders for cars, the cup holders need to undergo functional tests such as opening force and gripping force after molding. This is related to the customer's experience in the future and is an important part of the cup holder testing.

[0004] However, many companies still rely on quality supervisors to judge whether products are qualified. But each operator's subjective feeling is different, which leads to obvious differences in details even though the products look the same, resulting in a poor experience for car consumers.

[0007] By adopting the above technical solution, the cup holder to be tested is placed on the testing platform. The position of the cup holder is defined by the positioning component. Then, the moving component moves the cup holder to below the opening force detection component. The opening force detection component presses the cup lid of the cup holder and transmits the data of the force used to open the cup lid to the PLC control box. The laser sensor senses and records the time it takes for the cup lid to open and transmits the data to the PLC control box. Then, the moving component moves the cup holder to below the clamping force detection component. The clamping force detection component detects the clamping force of the cup holder on the cup and transmits the data to the PLC control box. The built-in algorithm of the PLC control box can compare the detected data with the required data to determine whether the product is qualified, thereby standardizing the testing process of the cup holder and improving the quality consistency of the cup holders after they leave the factory.

[0010] Optionally, the positioning column includes a support column segment vertically installed on the detection platform and a limiting column segment connected to the support column segment. The limiting column segment is located above the support column segment and has a diameter smaller than that of the support column segment. The limiting column segment coaxially and vertically passes through the mounting hole on the side wall of the cup holder. The diameter of the support column segment is larger than the diameter of the mounting hole.

[0011] Optionally, the positioning plate is installed on the detection platform, and the top of the positioning plate has a first slot and a second slot for engaging with the protrusion at the bottom of the cup holder. The first slot passes through the side wall of the positioning plate.

[0012] Optionally, the locking component includes a locking cylinder horizontally mounted on the detection platform. The output rod of the locking cylinder faces the positioning plate, and a locking rod is coaxially connected to the output rod of the locking cylinder. The side wall of the locking rod is provided with an arc surface that fits against the side wall of the cup holder.

[0013] Optionally, the pressing component includes a pressing cylinder installed on the testing platform. The output rod of the pressing cylinder is vertically arranged and connected to a connecting rod. The end of the connecting rod away from the locking cylinder is located above the positioning plate and connected to a vertically arranged pressing rod.

[0015] Optionally, the clamping force detection component includes a second servo module vertically mounted on the detection platform. The output end of the second servo module is connected to a water cup model, which matches the chamber inside the water cup holder for placing water cups. A first pressure sensor is provided between the water cup model and the second servo module to sense the force required to pull the water cup model away from the water cup holder.

A second pressure sensor for sensing the pressing force of the pressing rod is provided between the output end of the third servo module and the pressing rod.

[0017] In summary, this application includes at least one of the following beneficial technical effects of a general-purpose cup holder testing device: 1. Place the cup holder to be tested on the testing platform. The positioning component limits the position of the cup holder. Then, the moving component moves the cup holder to below the opening force detection component. The opening force detection component presses the cup lid of the cup holder and transmits the data of the force used to open the cup lid to the PLC control box. The laser sensor senses and records the time it takes for the cup lid to open and transmits the data to the PLC control box. Then, the moving component moves the cup holder to below the clamping force detection component. The clamping force detection component detects the clamping force of the cup holder on the cup and transmits the data to the PLC control box. The built-in algorithm in the PLC control box can compare the detected data with the required data to determine whether the product is qualified, thereby standardizing the testing process of the cup holder and improving the quality consistency of the cup holders after leaving the factory. 2. To mimic the effect of a cup holder mounted on a car, positioning posts restrict the side walls of the cup holder, positioning plates restrict the bottom of the cup holder, and locking components directly lock the position of the cup holder so that the holder does not wobble when the cup lid is pressed. The pressing component is used to test the clamping force of the cup holder and presses down on the cup holder to prevent it from moving upward when the cup model is pulled out.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a universal water cup holder 9 testing device. (Refer to...) Figure 1 and Figure 2 It includes a frame 1, on which a PLC control box 2, a moving component 4, a clamping force detection component 7, and an opening force detection component 8 are installed.

[0026] The movable component 4 is equipped with a detection platform 3 for placing the cup holder 9. The movable component 4 is used to move the detection platform 3 sequentially to the bottom of the opening force detection component 8 and the clamping force detection component 7. The opening force detection component 8 is used to detect the pressure on the cup holder 9 when the cup lid is opened, and the clamping force detection component 7 is used to detect the clamping force of the cup holder 9 on the cup after the cup lid is opened.

[0027] In addition, the detection platform 3 is equipped with a positioning component 5 for defining the position of the cup holder 9, and a laser sensor 6 is installed on the detection platform 3 to sense the time when the cup lid of the cup holder 9 is fully opened. The moving component 4, the opening force detection component 8, the clamping force detection component 7, and the laser sensor 6 are all electrically connected to the PLC control box 2 and all transmit the detected data to the PLC control box 2.

[0028] The moving component 4 moves the cup holder 9 to below the opening force detection component 8. The opening force detection component 8 presses the cup lid of the cup holder 9 and transmits the data of the force used to open the cup lid to the PLC control box 2. The laser sensor 6 senses and records the time it takes for the cup lid of the cup holder 9 to open and transmits the data to the PLC control box 2. Then, the moving component 4 moves the cup holder 9 to below the clamping force detection component 7. The clamping force detection component 7 detects the clamping force of the cup holder 9 on the cup and transmits the data to the PLC control box 2. The built-in algorithm of the PLC control box 2 can compare the detected data with the required data and automatically determine whether the product is qualified, thereby standardizing the inspection process of the cup holder 9 and improving the quality consistency of the cup holder 9 after leaving the factory.

[0029] Reference Figure 1 The moving component 4 includes a first servo module 41, a guide rail 42, and a guide platform 43.

[0030] The first servo module 41 and the guide rail 42 are both horizontally installed on the frame 1 along the layout direction of the opening force detection component 8 and the clamping force detection component 7. The guide platform 43 is installed on the first servo module 41 and is slidably connected to the guide rail 42. The detection platform 3 is installed on the guide platform 43 so that the detection platform 3 moves to the opening force detection component 8 first and then moves to the clamping force detection component 7.

[0031] Reference Figure 2 The opening force detection component 8 includes a third servo module 82 vertically mounted on the detection platform 3. The output end of the third servo module 82 is connected to a vertically arranged pressing rod 81. A second pressure sensor 83 for sensing the pressing force of the pressing rod 81 is provided between the output end of the third servo module 82 and the pressing rod 81.

[0032] The third servo module 82 and the pressing rod 81 together act as a human hand. The pressure data applied by the pressing rod 81 is transmitted to the PLC control box 2 via the second pressure sensor 83 to detect the pressure value required to open the cup lid of the cup holder 9 if pressure is applied by a human hand. The detected data is compared with the required data to determine whether the cup holder 9 is qualified.

[0033] To accurately measure whether the lid of the cup holder 9 is open and to record the opening time of the lid, refer to Figure 3 and Figure 4Two sets of laser sensors 6 are horizontally spaced along the opening direction of the cup holder 9. The cup holder 9 is located between the two sets of laser sensors 6. The probe height of the laser sensors 6 is located between the height of the cup holder 9 when the lid is closed and the height when it is open. This is to facilitate timely detection of changes in the opening angle of the cup lid and to transmit the detected data to the PLC control box 2, so that the PLC control box 2 can calculate the degree of opening and the time to full opening of the cup lid.

[0034] Reference Figure 2 The clamping force detection component 7 includes a second servo module 72 that is vertically mounted on the detection platform 3, and the output end of the second servo module 72 is connected to a water cup model 71.

[0035] The water cup model 71 matches the chamber inside the water cup holder 9 for placing the water cup. A first pressure sensor 73 is provided between the water cup model 71 and the second servo module 72 to sense the force required to pull the water cup model 71 out of the water cup holder 9.

[0036] The force required to insert and remove a water cup from the cup holder 9 is crucial for determining whether the cup holder 9 conforms to ergonomic design. Data on the force required to insert and remove the water cup model 71 from the cup holder 9 is transmitted to the PLC control box 2 via the first pressure sensor 73 for recording. The quality of the cup holder 9 is determined by comparing the detected data with the required data.

[0037] To simulate the scenario of cup holder 9 being installed in a car, the position of cup holder 9 needs to be defined, referring to... Figure 2 and Figure 3 The positioning component 5 includes a positioning post 51 that defines the position of the side wall of the cup holder 9, a positioning plate 52 that defines the position of the bottom of the cup holder 9, and a locking member 53 that locks the position of the cup holder 9. The positioning post 51, the positioning plate 52, and the locking member 53 are connected to the cup holder 9 when the cup holder 9 is placed on the detection platform 3, and remain connected until the entire detection process of the cup holder 9 is completed. However, before the cup holder 9 begins to undergo clamping force detection, in order to prevent the cup holder 9 from moving upward along with the cup model 71, a pressing member 54 is needed to press down the cup holder 9.

[0038] Among them, such as Figure 3 and Figure 4 As shown, the positioning column 51 includes a support column section 511 vertically installed on the detection platform 3 and a limiting column section 512 connected to the support column section 511. The limiting column section 512 is located above the support column section 511 and its diameter is smaller than that of the support column section 511. The limiting column section 512 coaxially and vertically passes through the mounting hole on the side wall of the cup holder 9. The diameter of the support column section 511 is larger than the diameter of the mounting hole.

[0039] like Figure 2 and Figure 3As shown, the cup holder 9 has multiple grooves, protrusions and holes for installation with the car. In order to fit the design of the cup holder 9 and position it, when the cup holder 9 is placed, the limiting column segment 512 passes through the mounting hole, and the supporting column segment 511 is used to support the side wall of the cup holder 9 where the mounting hole is opened, so as to achieve the initial horizontal limitation of the cup holder 9.

[0040] like Figure 2 and Figure 3 As shown, the positioning plate 52 is installed on the detection platform 3. The top of the positioning plate 52 has a first slot 521 and a second slot 522 for engaging with the protrusions on the bottom of the cup holder 9. This effectively restricts the horizontal position of the cup holder 9 from all directions. Figure 5 As shown, the first slot 521 extends through the side wall of the positioning plate 52 to facilitate observation of the placement of the cup holder 9 and reduce the difficulty of engaging the cup holder 9 with the positioning plate 52.

[0041] To prevent the cup holder 9 from shaking during later testing and affecting testing accuracy, its position needs to be locked. Figure 4 and Figure 5 As shown, the locking component 53 includes a locking cylinder 531 horizontally mounted on the detection platform 3. The output rod of the locking cylinder 531 faces the positioning plate 52, and the output rod of the locking cylinder 531 is coaxially connected to a locking rod 532. The side wall of the locking rod 532 has an arc surface that fits against the side wall of the cup holder 9. Two sets of locking components 53 are horizontally spaced along the opening direction of the cup lid of the cup holder 9 to improve the locking degree of the cup holder 9.

[0042] In addition, the pressing component 54 includes a pressing cylinder 541 installed on the detection platform 3. The output rod of the pressing cylinder 541 is vertically arranged and connected to a connecting rod 542. The end of the connecting rod 542 away from the locking cylinder 531 is located above the positioning plate 52 and is connected to a vertically arranged pressing rod 543.

[0043] When the moving component 4 moves the detection platform 3 below the clamping force detection component 7, the pressing component 54 begins to work. The pressing rod 543 moves downward to press against the cup holder 9, simulating the cup holder 9 being located inside a car. Afterward, the cup model 71 moves downward to insert into the cup holder 9 and then moves out of the cup holder 9 to prevent the cup holder 9 from moving upward and affecting the detection accuracy.

[0044] The implementation principle of a general-purpose water cup holder 9 detection device in this application embodiment is as follows: Before starting the detection, the operator places the water cup holder 9 on the positioning plate 52, with the limiting column segment 512 passing through the mounting hole. Then, the locking rod 532 clamps the side wall of the water cup holder 9. Afterward, the first servo module 41 drives the detection platform 3 to move directly below the third servo module 82. The third servo module 82 drives the pressing rod 81 to move down and press the cup lid switch of the water cup holder 9. The cup lid of the water cup holder 9 opens, and the laser sensor 6 and the second pressure sensor 83 transmit the detected cup lid opening time and cup lid opening force data to the PLC control box. 2. Then, the detection platform 3 moves directly below the second servo module 72. The pressing cylinder 541 drives the pressing rod 543 to press down against the cup holder 9. The second servo module 72 drives the cup model 71 to insert into the cup holder 9 and then pull it out of the cup holder 9. The first pressure sensor 73 transmits the force data required for the insertion and removal of the cup model 71 to the PLC control box 2. The built-in algorithm of the PLC control box 2 can compare the detected data with the required data and automatically determine whether the product is qualified, thereby standardizing the detection process of the cup holder 9 and improving the quality uniformity of the cup holder 9 after leaving the factory.

[0045] 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.
