Description

Technical Field

[0001] This utility model belongs to the field of chip assembly technology, specifically relating to a snap-fit ​​fixture for a USB receiver shell. Background Technology

[0002] Most existing electronic devices use USB interfaces for convenient and quick connection. Examples include receivers, transmitters, and wireless mice. A wireless mouse USB receiver consists of a housing and a circuit board installed inside the housing. The housing of the wireless mouse USB receiver is composed of a plastic shell and a metal shell, which are snapped together as one unit. See [link to documentation]. Figure 1 As shown, during the assembly of the USB receiver, the circuit board is first placed into the plastic casing, and then the combined plastic and metal casings are placed on the positioning table of the workbench. Finally, a pressing fixture is used to press the plastic and metal casings together. Currently, the pressing of USB receivers is done manually. However, the workpiece positioning slots on the positioning table are generally the same size and shape as the workpiece. This makes it difficult for workers to pick up and place the workpieces, especially when removing the pressed USB receiver. Because the USB receiver is small and thin, workers often have to use their fingernails to pry it out, which is not only easy to injure their hands but also inefficient. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a snap-fit ​​fixture for a USB receiver housing, which has a simple structure, reduces operational difficulty, and improves work efficiency.

[0004] The objective of this utility model and the technical solution adopted are as follows: A snap-fit ​​fixture for a USB receiver housing includes a worktable and a pressing jig disposed on the worktable. The pressing jig is provided with a positioning platform for positioning the workpiece, a pressing cylinder, and a pressing block. The pressing cylinder is located directly above the positioning platform. The pressing block is connected to the piston rod of the pressing cylinder. The lower end face of the pressing block is provided with a pressing head. The pressing end face of the pressing head is inclined. The positioning platform is provided with a workpiece positioning groove in the middle. The side of the workpiece positioning groove is provided with a clearance notch. The positioning platform is also provided with a part removal groove. The part removal groove is disposed on the side of the clearance notch and is connected to the workpiece positioning groove through the clearance notch.

[0005] Furthermore, the workpiece positioning groove has clearance notches on both opposing sides, and the positioning platform has two part-removal grooves.

[0006] Furthermore, the part-retrieving slot has an arc surface.

[0007] Furthermore, the part-retrieving slot extends to the side of the positioning platform.

[0008] Furthermore, the length of the clearance notch is less than the length of the workpiece positioning groove.

[0009] Furthermore, the clearance notch is located at the plastic housing end of the workpiece positioning groove.

[0010] Furthermore, the pressing fixture is provided with two pressing blocks, and the positioning platform is provided with a pair of workpiece positioning slots, with each pressing block corresponding to one workpiece positioning slot.

[0011] The above technical solution has the following beneficial effects: This invention features a simple structure. The pressing end face of the pressure head is beveled, ensuring improved product quality during the snap-fit ​​process. By creating a clearance notch and a part-removal slot on the side of the workpiece positioning groove on the positioning table, with the part-removal slot connected to the workpiece positioning groove via the clearance notch, it facilitates quick and stable manual removal and placement of the USB receiver workpiece. This simplifies operation, reduces operational difficulty, and improves manual work efficiency.

[0012] The pressing fixture is equipped with two pressing blocks, and the positioning table is equipped with a pair of workpiece positioning slots. Each pressing block corresponds to a workpiece positioning slot, which realizes the simultaneous pressing of two workpieces and improves the work efficiency by 100%.

[0013] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of an existing USB receiver; Figure 2 This is a schematic diagram of the structure of specific embodiment 1; Figure 3 This is a schematic diagram of the positioning stage in specific embodiment 1.

[0015] In the attached diagram, 1 is the worktable, 2 is the pressing fixture, 3 is the positioning table, 3-1 is the workpiece positioning groove, 3-2 is the clearance notch, 3-3 is the part removal groove, 4 is the pressing cylinder, 5 is the lower pressing block, 6 is the pressing head, and 7 is the mounting block. Detailed Implementation Specific Implementation Example 1:

[0016] See Figure 2 and Figure 3As shown, a snap-fit ​​fixture for a USB receiver housing includes a worktable 1 and a pressing jig 2 mounted on the worktable. The pressing jig 2 is an existing pneumatic pressing jig. The pressing jig 2 is equipped with a positioning platform 3 for positioning the workpiece, a pressing cylinder 4, and a lower pressing block 5. The positioning platform 3 has positioning steps at both ends and is mounted on the worktable 1 via mounting blocks 7 and adjusting screws at both ends. The pressing cylinder 4 is located directly above the positioning platform 3. The lower pressing block 5 is connected to the piston rod of the pressing cylinder 4. A pressing head 6 is mounted on the lower end face of the lower pressing block 5. The pressing end face of the pressing head 6 is inclined and is used to cooperate with the snap-fit ​​on the metal housing of the USB receiver to be processed. The pressing head 6 presses down on the snap-fit ​​on the metal housing of the USB receiver to be processed, snapping the snap-fit ​​on the metal housing of the USB receiver to be processed into the snap-fit ​​hole of the plastic housing, thus ensuring the processing quality.

[0017] The positioning platform 3 has a workpiece positioning groove 3-1 in the middle. The workpiece positioning groove 3-1 has the same shape as the USB receiver to be processed, which facilitates the positioning of the USB receiver in the workpiece positioning groove. The side of the workpiece positioning groove 3-1 has a clearance notch 3-2. The length of the clearance notch 3-2 is less than the length of the workpiece positioning groove 3-1. The clearance notch 3-2 is located at the plastic shell end of the workpiece positioning groove 3-1. The depth of the clearance notch 3-2 is 2-4mm. In this specific embodiment, the depth of the clearance notch 3-2 is 3.5mm. This depth does not affect the positioning of the USB receiver workpiece. The positioning platform 3 also has a picking groove 3-3. The picking groove 3-3 is located on the side of the clearance notch 3-1. The picking groove 3-3 is connected to the workpiece positioning groove 3-1 through the clearance notch 3-2, which facilitates the manual placement and clamping of the USB receiver workpiece through the picking groove and the clearance notch.

[0018] The workpiece positioning groove 3-1 has clearance notches 3-2 on both opposing sides, and the positioning platform 3-1 has two picking slots 3-3. In this specific embodiment, the clearance notches 3-2 are located on the two long sides of the workpiece positioning groove 3-1, making it easier for manual picking up of the workpiece from the left and right sides of the USB receiver, thus making the operation more convenient and efficient. The picking slots 3-3 are arc-shaped and extend to the side of the positioning platform, facilitating operation and preventing sharp corners from causing injury to workers.

[0019] Possibly, the pressing fixture 2 is provided with two pressing blocks 5, and the movable end of the pressing cylinder 4 is connected to the two pressing blocks 5. The positioning table 3 is provided with a pair of workpiece positioning grooves 3-1, each pressing block 5 corresponds to one workpiece positioning groove 3-1, and the two workpiece positioning grooves 3-1 are located on the same center line. The sides of the two workpiece positioning grooves 3-1 are provided with clearance notches 3-2 and part removal grooves 3-3, which realizes the simultaneous pressing and processing of two workpieces and further improves work efficiency.
