Abstract
Description
Technical Field
[0001] This application relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for detecting missing magnets in a mouse. Background Technology
[0002] The magnetic force generated by the magnet inside the mouse bounces the mouse back, using the principle of magnetic fields to achieve button elasticity recovery. The magnet provides the rebound force, thereby reducing mechanical wear, extending button life, and improving user comfort. However, during the mouse assembly process, because the magnet is too small and embedded in the mouse shell, it is not easy to observe whether the magnet is present inside the mouse. Furthermore, during the transportation or assembly process, the magnet may detach from the mouse. Afterward, the staff needs to carefully observe it in subsequent processes, which reduces the pass rate of the mouse. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a tooling fixture for detecting missing magnets in mice.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] The device includes an upper template and a lower template. The upper end of the lower template has an installation groove, and the bottom of the installation groove has multiple sensing optical fibers, each of which corresponds to the installation position of the mouse magnet. The lower end of the upper template has multiple hot-melt pillars, each of which corresponds to the multiple sensing optical fibers.
[0006] Preferably, two mounting slots are evenly provided at the upper end of the lower template.
[0007] Preferably, a positioning block is provided at the bottom of the mounting groove.
[0008] Preferably, a moving component is provided below the lower template. The moving component includes a pushing cylinder and a bracket. The bracket is located at the lower end of the lower template, and the output end of the pushing cylinder is connected to the side wall of the bracket.
[0009] Preferably, the lower end of the bracket is provided with a guide member, the guide member including a slider and a guide rail, the slider is disposed on the lower end face of the bracket, and the slider slides on the guide rail.
[0010] Preferably, a feeding assembly is provided on one side of the upper template. The feeding assembly corresponds to the lower template. The feeding assembly includes a mounting plate, a driving cylinder, a screening plate, and multiple storage pipes. The mounting plate corresponds to the lower template. Multiple through holes are opened at the upper end of the mounting plate. The multiple through holes correspond to multiple sensing optical fibers. The multiple storage pipes are located on the mounting plate. The screening plate is located between the multiple storage pipes and the mounting plate. Multiple screening holes are opened through the upper surface of the screening plate. The driving cylinder drives the screening plate to move back and forth, so that the screening holes correspond to the storage pipes and the through holes respectively.
[0011] Preferably, the side wall of the mounting plate is provided with a lifting cylinder, which drives the unloading assembly to move up and down.
[0012] In summary, the beneficial technical effects of this application are as follows:
[0013] First, the tooling fixture is installed on the hot melt machine. Then, the magnet is placed inside the mouse through the feeding assembly. The mouse is then placed in the mounting slot of the lower template. The sensing fiber in the mounting slot of the lower template will then correspond to the position of the magnet installed on the mouse, thus sensing whether there is a magnet inside the mouse. When there is no magnet missing inside the mouse, the push cylinder is activated to push the lower template under the upper template. Then, the upper and lower templates move closer to each other, so that the hot melt column of the upper template presses on the mouse. The heat from the hot melt machine is transferred to the mouse through the upper template and the hot melt column, which melts the mounting hole of the magnet on the mouse, thereby locking the magnet firmly inside the mouse. This makes it difficult for the magnet to come out of the mouse, improving the pass rate of the mouse. Attached Figure Description

[0024] Reference Figure 4 The moving component 2 includes a push cylinder 6 and a bracket 7. A guide 8 is placed between the bracket 7 and the base plate 1. The guide 8 includes two sliders 9 and two guide rails 10. The two guide rails 10 are horizontally parallel and fixed to the base plate 1 with bolts. The two sliders 9 slide horizontally on the two guide rails 10 respectively. The bracket 7 is fixed to the two sliders 9 with bolts. The push cylinder 6 is horizontally mounted on the base plate 1, and the output end of the push cylinder 6 is fixed to the bracket 7. The lower template 4 is mounted and fixed above the bracket 7, and the upper template 3 is mounted on the lower end face of the heating plate of the hot melt machine. The push cylinder 6 pushes the lower template 4 to slide on the base plate 1. The lower template 4 will slide to below the upper template 3, or it can slide out of the hot melt machine.
[0025] Reference Figure 3 The lower template 4 has two evenly spaced mounting slots 11 on its upper surface. The mounting slots 11 can fit against the outer side wall of the mouse. A positioning block 12 is integrally provided at the bottom of the mounting slot 11. The positioning block 12 can be embedded in the side wall of the mouse. The lower template 4 has three through holes at the bottom of the mounting slots 11. A sensing fiber 13 is vertically fixed in the through holes. The upper end of the sensing fiber 13 corresponds to the magnet mounting hole of the mouse. Six hot melt pillars 14 are vertically installed at the lower end of the upper template 3. The hot melt pillars 14 are placed vertically, and the lower ends of the six hot melt pillars 14 correspond to the six sensing fibers 13 in the two mounting slots 11 respectively.
[0026] Reference Figure 5The feeding assembly 5 is located above the lower template 4 near the pushing cylinder 6. The feeding assembly 5 includes a mounting plate 15, a driving cylinder 16, a screening plate 21, and three storage pipes 17. The mounting plate 15 is horizontally placed, and the screening plate 21 slides horizontally on the upper surface of the mounting plate 15. The driving cylinder 16 is horizontally mounted above one side of the mounting plate 15, and its output end is connected to the side wall of the screening plate 21. The storage pipes 17 are vertically placed, and their lower ends are mounted on a fixing frame. One end of the fixing frame is fixed to the mounting plate 15. On the upper end, the screening plate 21 is located between the storage pipe 17 and the mounting plate 15. The upper end of the screening plate 21 has three screening holes 18. The upper end of the mounting plate 15 has three through holes 19. The three through holes 19 correspond to the three sensing optical fibers 13 respectively. The lower end of the mounting plate 15 is welded and fixed with six feeding pipes. The upper ends of the six feeding pipes correspond to the six through holes 19. Under the push of the driving cylinder 16, the screening plate 21 can move the screening holes 18 back and forth between the lower end outlet of the storage pipe 17 and the through holes 19.
[0027] Two lifting cylinders 20 are vertically mounted on the upper surface of the base plate 1, and the output ends of the two lifting cylinders 20 are fixed to the corresponding side walls of the mounting plate 15.
[0028] The implementation principle of a tooling fixture for detecting missing magnets in a mouse, as disclosed in the embodiments of this application, is as follows:
[0029] After the magnet is placed inside the mouse through the feeding assembly 5, the mouse is first placed in the mounting slot 11 of the lower template 4. Then, the sensing fiber optic cable 13 in the mounting slot 11 of the lower template 4 will correspond to the position of the mouse magnet, thereby sensing whether there is a magnet inside the mouse. When there is no missing magnet inside the mouse, the pushing cylinder 6 is activated to push the lower template 4 under the upper template 3. Then the upper template 3 and the lower template 4 move closer to each other, so that the hot melt column 14 of the upper template 3 presses on the mouse. The heat from the hot melt machine is transferred to the mouse through the upper template 3 and the hot melt column 14, which then melts the mounting hole of the magnet on the mouse, thereby locking and fixing the magnet inside the mouse.
