Description

Technical Field

[0001] This application relates to the field of tooling and fixture technology, and in particular to a fixture for detecting mouse scroll wheel sway and misalignment. Background Technology

[0002] As the requirements for gaming mice developed for clients become increasingly sophisticated, the quality demands on the products also rise. This necessitates various tests on the mice, such as the detection of scroll wheel misalignment. Scroll wheels can shift during production or assembly, resulting in a low pass rate for mice. While testers rely on observation and touch to detect scroll wheel misalignment, misjudgments frequently lead to defective products entering the market, further contributing to the low pass rate. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a fixture for detecting mouse scroll wheel misalignment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes a base, a stabilizer, a drive air nozzle, and a laser detection head. The upper end of the base has a placement slot for a roller bracket. The stabilizer is located above the base and locks the roller bracket. One end of the drive air nozzle is located on the outside of the stabilizer. The laser detection head is located on one side of the base, and the end of the laser detection head corresponds to the roller. When the stabilizer and the base abut against each other and lock the roller bracket, the inner end of the drive air nozzle corresponds to the roller.

[0006] Preferably, a drive cylinder is provided at the upper end of the stabilizer, and the drive cylinder drives the stabilizer to move closer to or away from the base.

[0007] Preferably, a mounting plate is provided on the outer side of the stabilizer, and a mounting hole is provided on the side wall of the mounting plate. The drive air nozzle is installed and fixed in the mounting hole. An adjustment groove is provided on the side wall of the mounting plate. The inner end of the adjustment groove is connected to the mounting hole. A locking member is provided in the side wall of the mounting plate. The locking member includes a fixing screw and an adjusting nut. One end of the fixing screw passes through the side wall of the mounting plate and through the adjustment groove. The adjusting nut is threaded to the periphery of the fixing screw.

[0008] Preferably, the lower end of the stabilizer is provided with a groove, and a spare air nozzle is provided in the groove, the lower end of which corresponds to the roller.

[0009] Preferably, a fixing frame is provided on one side of the laser detection head, and an adjustment plate is provided on the side wall of the fixing frame. The laser detection head is installed and fixed on the outer side wall of the adjustment plate. A slider is provided on the inner side of the adjustment plate. A sliding groove is provided on the side wall of the fixing frame for the slider to slide vertically. A lifting cylinder is provided at the upper end of the fixing frame, and the output end of the lifting cylinder is provided on the slider.

[0010] Preferably, the upper end face of the base has a limiting post, which is inserted into the roller bracket.

[0011] Preferably, the base has a guide slope on the side wall of the placement groove.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When it is necessary to test the sway and misalignment of the scroll wheel, first place the assembled scroll wheel and scroll wheel bracket in the placement slot. Then, drive the cylinder to drive the stabilizer to descend until the stabilizer and the base abut against each other. The inner end of the drive nozzle is aligned with the scroll wheel. Then, the drive nozzle generates gas and blows the scroll wheel. At this time, the end of the laser detection head can detect the scroll wheel and thus determine whether the scroll wheel is qualified, thereby improving the pass rate of the mouse.

[0014] 2. When the drive nozzle is affected, when the base and the stabilizer are in contact, the lower end of the spare nozzle corresponds to the roller. Then, air is blown out of the spare nozzle and blows the roller, which can prevent the roller from being unable to be inspected when the drive nozzle is damaged, thus improving the stability of the tooling fixture.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This application discloses a fixture for detecting mouse scroll wheel skew.

[0021] Reference Figure 1 The system includes a frame 1, a base 2, a stabilizer 3, a mounting bracket 4, a drive cylinder 5, a drive nozzle 6, and a laser detection head 7. The base 2 is fixed to the frame 1 with bolts. The mounting bracket 4 is placed vertically, and its lower end is fixed to the frame 1 with bolts. The drive cylinder 5 is placed vertically and fixed to the upper end of the mounting bracket 4. The stabilizer 3 is fixed to the output end of the drive cylinder 5. The upper end of the base 2 has a placement groove 8, which can accommodate a roller bracket. Two limiting posts 9 are inserted and fixed to the upper end of the base 2. The two limiting posts 9 are located on both sides of the placement groove 8. The roller bracket is sleeved and fixed to the periphery of the two limiting posts 9. The base 2 has guide slopes 10 on both sides of the placement groove 8.

[0022] Reference Figure 2 The laser detection head 7 is located on one side of the base 2, with its end corresponding to the roller on the roller bracket. A mounting plate 11 is fixed to the outer side of the stabilizing seat 3. The side wall of the mounting plate 11 has a mounting hole 12, and one end of the drive nozzle 6 is inserted into the mounting hole 12. A through hole is formed on the side wall of the stabilizing seat 3, with the mounting hole 12 corresponding to the through hole. The assembled roller and roller bracket are placed in the placement groove 8. Then, the drive cylinder 5 lowers the stabilizing seat 3 until it abuts against the base 2. At this point, the inner end of the drive nozzle 6 corresponds to the roller, and the drive nozzle 6 generates gas to blow on the roller. The end of the laser detection head 7 can then detect the rolling roller, thus determining whether the roller is qualified.

[0023] The lower end of the mounting plate 11 has an adjustment groove 13, the upper side of which communicates with the mounting hole 12. The lower end of the mounting plate 11 contains a locking element 14, which includes a fixing screw 15 and an adjusting nut 16. One end of the fixing screw 15 enters from one side of the mounting plate 11, passes through the adjustment groove 13, and finally exits from the other side of the mounting plate 11. The adjusting nut 16 is threaded onto the periphery of one end of the fixing screw 15. When the drive nozzle 6 needs to be disassembled, the adjusting nut 16 is rotated away from the mounting plate 11, thereby loosening the adjustment groove 13. The drive nozzle 6 can then be pulled out of the mounting hole 12, improving the ease of disassembling the drive nozzle 6.

[0024] The lower end of the stabilizer 3 has a groove 17. The vertical cross-section of the stabilizer 3 is U-shaped. A spare air nozzle 18 is inserted and fixed at the bottom of the groove 17. The lower end of the spare air nozzle 18 corresponds vertically to the roller. When the drive air nozzle 6 is affected, when the base 2 and the stabilizer 3 abut against each other, the lower end of the spare air nozzle 18 corresponds to the roller. Then, air is blown out of the spare air nozzle 18 and blows the roller, thus preventing the roller from being unable to be detected when the drive air nozzle 6 is damaged.

[0025] Reference Figure 3 A mounting bracket 19 is fixed to the frame 1. An adjusting plate 20 is placed on one side of the mounting bracket 19. The side wall of the laser detection head 7 is mounted on the outside of the adjusting plate 20. A slider 21 is fixed to the adjusting plate 20 on the side near the mounting bracket 19. A vertical groove 22 is formed on the side wall of the mounting bracket 19. The slider 21 slides vertically within the groove 22. The end of the slider 21 away from the adjusting plate 20 protrudes from the side wall of the mounting bracket 19. A lifting cylinder 23 is vertically mounted on the upper end of the mounting bracket 19. The output end of the lifting cylinder 23 is fixed to the side wall of the slider 21. When the model of the roller bracket changes, the height of the roller on the base 2 changes. Then, the lifting cylinder 23 pulls the slider 21 to slide vertically within the groove 22, thereby moving the laser detection head 7 up and down until the end of the laser detection head 7 corresponds to the roller.
