Description

Technical Field

[0001] This utility model belongs to the field of chip assembly technology, specifically relating to a heat-sealing tooling for a receiver assembly plastic housing. 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 is composed of a plastic shell and a metal shell. The plastic shell has rectangular locking holes that engage with spring clips on the metal shell to form a snap-fit ​​assembly. The plastic shell is also composed of two interlocking parts, facilitating circuit board installation and enabling modular assembly. Grooves are also provided on the top and bottom surfaces of the plastic shell to increase the contact area for fingers, making insertion and removal smoother. See [link to documentation]. Figure 1 As shown.

[0003] After the circuit board of the USB receiver is installed inside the plastic casing, since the plastic casing consists of two parts that interlock, a heat sealing machine is needed to heat seal the two parts of the plastic casing together. In the existing USB receiver heat sealing process, when the welding head presses down to contact the workpiece, the workpiece is prone to displacement, thus affecting the heat sealing effect of the USB receiver. Furthermore, the heat sealing process involves manual handling of the workpiece; however, the workpiece positioning grooves on the positioning table of the heat sealing machine are generally the same shape and size as the workpiece product. This makes it difficult for workers to handle the workpiece, especially when removing the heat-sealed USB receiver workpiece, which requires using fingernails to pry it out, which is not only easy to injure hands but also inefficient. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a heat-sealing fixture for a receiver assembly plastic housing. This fixture has a simple structure, reduces operational difficulty, and improves the accuracy and efficiency of housing heat sealing.

[0005] The objective of this utility model and the technical solution adopted are as follows: A heat-sealing fixture for a receiver-type plastic housing includes a worktable, a heat-sealing machine mounted on the worktable, and a positioning table for positioning the workpiece. The heat-sealing machine includes a welding assembly with a welding head positioned directly above the positioning table. The lower end face of the welding head has a first pressure head for positioning the slot of the plastic housing to be processed and a second pressure head for positioning the groove of the plastic housing to be processed. The positioning table has a workpiece positioning groove in the middle, and a clearance notch is provided on the side of the workpiece positioning groove. The positioning table also has a part-removing groove located on the side of the clearance notch and connected to the workpiece positioning groove through the clearance notch.

[0006] Furthermore, the lower end face of the welding head is provided with a pressure block, and the first pressure head and the second pressure head are disposed on the pressure block.

[0007] Furthermore, the lower surface of the first pressure head is a slope, and the first pressure head cooperates with the card hole of the plastic shell to be processed.

[0008] Furthermore, the pressure block is provided with two first pressure heads, each of which corresponds to a card hole in the plastic shell to be processed.

[0009] Furthermore, the heat sealing machine is an ultrasonic welding fixture.

[0010] Furthermore, the workpiece positioning groove has clearance notches on both opposing sides, and the positioning platform has two part-removal grooves.

[0011] Furthermore, the clearance notch is located at the plastic housing end of the workpiece positioning groove.

[0012] Furthermore, the workpiece positioning groove is provided with positioning ribs for positioning the groove of the plastic shell to be processed.

[0013] Furthermore, the part-retrieving slot has an arc surface.

[0014] Furthermore, the part-retrieving slot extends to the side of the positioning platform.

[0015] The above technical solution has the following beneficial effects: This invention features a simple structure. By adding a first pressure head for positioning the locking hole of the plastic housing to be processed and a second pressure head for positioning the groove of the plastic housing to be processed on the lower end face of the welding head, positioning is achieved by the first and second pressure heads engaging with the locking hole and groove of the plastic housing, ensuring the accuracy of heat sealing during plastic housing assembly. Simultaneously, by creating a clearance notch and a part-removal groove on the side of the workpiece positioning groove on the positioning table, with the part-removal groove connected to the workpiece positioning groove through the clearance notch, it facilitates quick and stable manual handling of USB receiver workpieces, simplifying operation, reducing operational difficulty, and improving work efficiency.
