Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a headrest conduit button thrust testing device. Background Art

[0002] In the manufacture of car seats, there are many parts and components required for car seats, such as the headrest rod guide, which is used to make the headrest easy to install on the car seat. Figure 1 As shown), it includes a catheter body 01, an unlocking button 02, a baffle 03 and a compression spring 04. The unlocking button 02 includes an integrally formed push head 021 and a slider 022. A guide channel 011 is provided in the catheter body 01, which runs through it from top to bottom. A blind hole 012 and a sliding hole 013 are provided on the upper part of the catheter body 01. The upper end opening of the guide channel 011 is located between the blind hole 012 and the sliding hole 013. The slider 022 passes through the sliding hole 013, the guide channel 011 and the blind hole 012 in sequence. The inner end of the slider 022 is connected to the blind hole 012 through the compression spring 04. The push head 021 is located on the outside of the sliding hole 013. A guide hole 023 is provided on the slider 022, which runs through it from top to bottom. The diameter of the guide hole 023 is larger than the inner diameter of the guide channel 011. The baffle 03 is installed on the slider 022 and covers part of the outline of the guide hole 023. The remaining outline diameter of the guide hole 023 is greater than or equal to the inner diameter of the guide channel 011. When compression spring 04 is in its normal position, baffle 03 partially covers guide channel 011. To insert the headrest rod into the headrest rod guide, press button 021, compressing compression spring 04. Slider 022 drives baffle 03 toward blind hole 012, fully opening guide channel 011 (unobstructed by baffle 03). The headrest rod is then passed through the remaining contour of guide hole 023 and guide channel 011 from top to bottom. The pressing force of button 021 is then released, causing compression spring 04 to return to its original position, causing slider 022 to drive baffle 03 toward sliding hole 013, allowing baffle 03 to snap into place with the notch in the headrest rod. Typically, headrest rod guides undergo a button thrust test before shipment to verify that compression spring 04 is installed between unlock button 02 and guide body 01, and whether compression spring 04 rebounds after being pressed. This ensures that the quality of the headrest rod guide meets standards before assembly.

[0003] However, the structure of traditional thrust testing equipment is relatively complex, the testing time of a single headrest rod guide is long, and it is impossible to push the unlocking buttons of multiple headrest rod guides at the same time, resulting in low detection efficiency. It is only suitable for random inspections and it is difficult to achieve full inspection of the product, which cannot meet the needs of large-scale industrial production. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a headrest duct button thrust testing device, which has a simple structure and can simultaneously perform thrust tests on the unlocking buttons of multiple headrest rod ducts, thereby improving detection efficiency.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0006] A headrest duct button thrust test device, characterized in that it includes a frame, a display, at least two push blocks, at least two pressure sensors, a fork clamping mechanism and a thrust mechanism capable of simultaneously driving each push block to move, the frame is provided with a conveying guide rail capable of allowing each headrest duct to pass through, the conveying guide rail is provided with a test station, the fork clamping mechanism is installed on the frame, and the fork clamping mechanism is provided with at least two clamping claws arranged at equal intervals along the conveying direction of the conveying guide rail, each clamping claw is located below the test station, and each clamping claw faces the conveying guide rail and respectively engages with the corresponding clamping claw on the test station. The thrust mechanism is installed on the frame and corresponds to the test station, the power output end of the thrust mechanism faces the conveying guide rail, and each push block can be slidably installed on the frame and arranged at equal intervals along the conveying direction of the conveying guide rail, and each push block is connected to the power output end of the thrust mechanism; each pressure sensor is respectively installed on the inner side surface of the corresponding push block, and the inner side surface of each push block is respectively in contact with the unlocking button of the corresponding headrest duct on the test station, the display is installed on the frame, and the signal output end of each pressure sensor is electrically connected to the signal input end of the display.

[0007] The above definitions of inside and outside are: with the conveyor rail as the center, the side close to the conveyor rail is the inside, and the side away from the conveyor rail is the outside.

[0008] During the test, each neatly arranged headrest tube to be tested is conveyed one by one into the conveying guide rail so that the unlocking button on the headrest tube corresponds to the inner side surface of the push block; then, when each headrest tube is conveyed to the test station, the power output end of the fork clamping mechanism is driven to move toward the lower part of the corresponding headrest tube, and the lower part of the corresponding headrest tube is clamped and positioned by each clamping claw; then, the inner side surface of each push block is simultaneously driven by the thrust mechanism to contact and cooperate with the unlocking button of the corresponding headrest tube on the test station. If a compression spring is installed between the unlocking button and the headrest tube, under the push of the push block, the pressure sensor senses the pressure signal and sends the pressure signal to the display. The pressure of the unlocking button throughout the test is displayed in real time on the display, so as to observe whether a compression spring is installed in the headrest tube and whether the compression spring will rebound and reset after being pressed.

[0009] In a preferred embodiment, the fork clamping mechanism includes a translation cylinder, a first mounting plate, and at least two finger cylinders. The translation cylinder is mounted on the frame, and the piston rod of the translation cylinder extends toward the conveying rail. The first mounting plate is mounted on the end of the piston rod of the translation cylinder. The cylinder body of each finger cylinder is mounted on the first mounting plate, and the two clamping fingers of the finger cylinder form the clamping claw. The frame is provided with a first slide rail running inward and outward, and the first slide rail is mounted on the first slide rail. The first slide rail is connected to the lower end of the cylinder body of the finger cylinder. The piston rod of each translation cylinder extends toward the conveying rail, driving the finger cylinder to clamp the lower portion of the corresponding headrest catheter delivered to the test station, ensuring that the headrest catheter can be fixed during testing and improving testing efficiency.

[0010] In a preferred embodiment, the frame is provided with a second slide rail extending inward and outward, a second slider mounted on the second slide rail, and the second slider is connected to the lower end of the push block. The thrust mechanism is a cylinder with an inwardly extending piston rod. The end of the cylinder piston rod is connected to a second mounting plate, and each push block is mounted on the second mounting plate. The combination of the second slide rail and the second slider ensures the straightness of the push block during translation, preventing lateral deviation, thereby improving test accuracy.

[0011] In a preferred embodiment, a sensor slot is provided on the inner side of the push block, and the pressure sensor is mounted in the sensor slot. The sensor slot is used to mount the pressure sensor, making installation and removal of the pressure sensor more convenient, facilitating maintenance and replacement, and ensuring that the pressure sensor is securely fixed during testing, thereby avoiding measurement errors caused by loose pressure sensors.

[0012] In a preferred embodiment, the inner side surface of the push block is a curved surface. The curved surface design allows the push block to better adapt to unlocking buttons of different shapes and sizes, thereby improving the versatility of the device.

[0013] In a preferred embodiment, the headrest duct button thrust test device further includes a visual alignment unit; the visual alignment unit is positioned above the conveyor rail, with the imaging end of the visual alignment unit facing the test station, and the signal output end of the visual alignment unit is electrically connected to the signal input end of the display. By adding the visual alignment unit, it is possible to automatically detect whether a baffle is installed in the headrest duct at the test station and whether the baffle normally covers a portion of the guide channel, thereby achieving dual detection of the headrest duct. The operator can also use the visual alignment unit to monitor the test process in real time, promptly identifying and addressing abnormalities.

[0014] In a further preferred embodiment, the visual alignment unit is a camera, and a signal output terminal of the camera is electrically connected to a signal input terminal of the display.
