Technical Field

[0001] This utility model relates to the field of dispensing technology, and in particular to a dispensing mechanism. Background Technology

[0002] A mouse is a handheld input device used to control a computer's graphical interface. It controls the screen pointer by detecting planar movement, enabling precise positioning, selection, dragging, and other interactive operations.

[0003] During mouse manufacturing, a dispensing mechanism is used to apply glue, assemble the mouse buttons, bond the outer shell, and secure the circuit board. Mice generally come in different sizes to accommodate different hand shapes, and the glue container used for each size differs. Therefore, the glue container needs to be changed during manufacturing. However, current dispensing mechanisms typically use screws to assemble the robotic arm and the glue container, making glue container replacement cumbersome. Utility Model Content

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] This embodiment provides a dispensing mechanism, such as Figure 1As shown, the device includes a dispensing cylinder 1 and a needle 2 located at the bottom of the dispensing cylinder 1, as well as several fixing parts. The fixing parts are used to fix the dispensing cylinder 1 to the robotic arm. The fixing parts include a strap 4 and a locking part 5. The locking part 5 includes a locking block 51 and an adjustment part 52 located on the locking block 51. The strap 4 is made of flexible material, one end of which is fixedly connected to the locking block 51, and the other end can pass through the locking block 51 and be fixed by the adjustment part 52.

[0025] like Figure 4 As shown, the strap 4 includes a mesh 41 and a protective layer 42, with the protective layer 42 fixedly disposed on the outer ring of the mesh 41. The mesh 41 is made of metal mesh, which has a certain strength and can deform. When the strap 4 is wrapped around the outside of the dispensing cylinder 1, the two can fit tightly together, preventing the dispensing cylinder 1 from shaking inside the strap 4. The protective layer 42 is made of fabric, and the soft fabric cushions the pressure of the protective layer 42 on the dispensing cylinder 1, preventing the dispensing cylinder 1 from being damaged.

[0026] like Figure 2 As shown, the locking block 51 has a threading hole 53 in the middle for the strap 4 to pass through. The threading hole 53 has a groove 54 on the right side and a through groove 55 on the left side. The size of the threading hole 53 is slightly larger than the size of the strap 4 to ensure that the free end of the strap 4 can pass smoothly through the threading hole 53.

[0027] The through groove 55 is provided with several left protrusions 56, which are fixedly connected to the locking block 51. The tips of the left protrusions 56 face outward and are flush with the edge of the locking block 51 on the same side, so as to prevent the strap 4 from rubbing against the left protrusions 56 when it is inserted into the strap hole 53, thus preventing the strap 4 from passing through.

[0028] like Figure 3 As shown, the adjustment part 52 includes an adjustment plate 521, which is located in the groove 54 and can slide back and forth along the groove 54. Several right protrusions 522 are fixedly provided on the outer side of the adjustment plate 521. Left protrusions 56 and right protrusions 522 are arranged alternately and inserted into adjacent meshes of the mesh 41. After the strap 4 passes through the threading hole 53, the right protrusions 522 press the strap 4 against the left protrusions 56. The misaligned left protrusions 56 and right protrusions 522 are inserted into different meshes of the mesh 41, strengthening the fastening force on the strap 4 and preventing the strap 4 from coming out of the threading hole 53. The tips of the right protrusions 522 face outwards. When the adjustment plate 521 is completely located in the groove 54, the tips of the right protrusions 522 are flush with the edge of the locking block 51 on the same side, preventing friction between the strap 4 and the right protrusions 522 when the strap 4 passes through the threading hole 53, thus preventing the strap 4 from passing through.

[0029] A threaded rod 523 is rotatably connected to the inner side of the adjusting plate 521 via a bearing. The threaded rod 523 passes through the locking block 51 and is threadedly connected to the locking block 51. The threaded rod 523 is long enough that when the adjusting plate 521 moves towards the through groove 55 and squeezes the strap 4, the outer end of the threaded rod 523 remains outside the locking block 51. A knob 524 for rotating the threaded rod 523 is fixedly provided at the outer end of the threaded rod 523.

[0030] Several guide rods 525 are fixedly provided on the outer side of the adjusting plate 521, and all guide rods 525 are slidably connected to the locking block 51. The guide rods 525 are long enough that when the adjusting plate 521 moves toward the through groove 55 and squeezes the strap 4, the outer end of the guide rod 525 remains outside the locking block 51.

[0031] A connecting block 3 is fixedly provided at one end of the locking block 51. The adjusting plate 521 can be fixed to the robotic arm through the connecting block 3. When the robotic arm moves, it drives the dispensing cylinder 1 and the needle 2 to move, so as to dispense glue onto the mouse.

[0032] The top of the dispensing cylinder 1 is provided with a top cover 6, which can be connected to the dispensing cylinder 1 by means of thread or plug-in connection, and a sealing strip is provided between the two. The top cover 6 is provided with a conduit 7, which is connected to an air pump. The air pump pumps compressed gas into the dispensing cylinder 1 to force the glue out from the needle 2.

[0033] In use, insert the free end of the strap 4 into the threading hole 53 to form a loop. Place the glue dispenser 1 in the loop and tighten its free end, pressing the glue dispenser 1 against the locking block 51. While tightening the free end, turn the knob 524 to rotate the threaded rod 523, pushing the adjusting plate 521 towards the left protrusion 56 until the strap 4 is firmly locked between the left protrusion 56 and the right protrusion 522. Stop turning the knob 524, release the free end, and the free end of the strap 4 is fixed to the locking block 51. Fix the glue dispenser 1 to the adjusting plate 521. Tighten all the locking parts 5 in the same way.

[0034] Start the robotic arm and air pump. The robotic arm moves the needle 2, and the air pump pushes the glue in the dispensing tube 1 out from the needle 2 to perform the glue dispensing operation on the mouse.

[0035] By incorporating a deformable strap 4, it can be fitted to the outer wall of dispensing cylinders 1 of different diameters. The adjusting part 52 can fix the free end of the strap 4 to the locking block 51, ensuring that the strap 4 firmly grips the dispensing cylinder 1. The strap 4 and the locking part 5 work together to fix dispensing cylinders 1 of different diameters onto the robotic arm without the need to replace the strap 4 and the locking part 5, which not only simplifies operation but also saves resources.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
