Description

Technical Field

[0001] The present invention relates to the technical field of switches, and in particular to a touch switch assembly device. Background Art

[0002] Existing tactile switch assembly equipment suffers from low efficiency, insufficient precision, and poor adaptability in automated production. Traditional equipment typically utilizes fixed molds, making it difficult to quickly switch between different switch assembly models, limiting production flexibility.

[0003] Cutting components are often fixed blades, which are time-consuming to replace after wear, and the cutting precision of the connecting strips is insufficient to meet the assembly requirements of high-density switches. Existing technology often relies on mechanical clips for base positioning, which lacks stability and is prone to misalignment, especially during high-speed production, resulting in a decrease in yield. Furthermore, the lack of a real-time detection and feedback system makes it difficult to detect equipment failures in a timely manner, increasing maintenance costs. Therefore, there is an urgent need for a touch switch assembly device with high precision, modular design, and intelligent control to address these technical pain points. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figure 1 The illustrated tactile switch assembly apparatus includes a base mold assembly 20. A first feed port 201 and a second feed port 202 are respectively provided on two adjacent sides of the base mold assembly 20. In this embodiment, there are two second feed ports 202, located on the same side. The first feed port 201 is at a higher level than the second feed port 202. A combination area 203 is provided in the center of the base mold assembly 20. Within this combination area 203 are at least one rectangular array of grooves 204. In this embodiment, there are four grooves 204, two of which have different shapes from the other two. Their specific shapes depend on the combined shape of the dragged objects on the material strip.

[0036] The material strip includes a first material strip 31 and a second material strip 32 . The second material strip 32 carries the base of the touch switch, and the first material strip 31 carries the components set in the base, the assembled key components and the upper cover.

[0037] A pressure sensor 205 is mounted at the bottom of the groove 204 to detect the placement of the base. A magnetic positioning block is embedded in the groove 204 to enhance the positioning accuracy of the base. The bottom mold assembly 20 is made of high-strength aluminum alloy and coated with a wear-resistant coating to improve durability.

[0038] First material strip 31 enters base mold assembly 20 through first inlet 201, and second material strip 32 enters through second inlet 202. Both strips are equipped with guide structures that mate with guide rails 208 within base mold assembly 20 to ensure the stability of their trajectory. First material strip 31 carries the components within the base, while second material strip 32 carries the base. The components and base are assembled within assembly area 203.

[0039] The transmission assembly 40 includes a pulley 41 and a timing belt (not shown). The timing belt is mounted on the pulley 41, with its ends fixed to the ends of the first and second material strips 31 and 32, respectively. The transmission assembly 40 is controlled by a programmable logic controller (PLC) control system 60, which coordinates the operation of the transmission assembly 40 and the drive unit. The drive unit utilizes a servo motor 71, which is connected to the upper mold assembly 80 via a linkage mechanism. The linkage mechanism is designed as a multi-stage articulated structure to precisely control the vertical travel and speed of the upper mold assembly 80. The upper mold assembly 80 is located directly above the base mold assembly 20. A replaceable cutter 81 is mounted at its base. The blade of cutter 81 is made of carbide and is pneumatically driven to achieve rapid cutting action. The cutter 81 is positioned directly opposite the groove 204 and is used to sever the connecting strip between the material strip and the base or assembly. It should be noted that driving the material strip back and forth within the mold is conventional technology. Regardless of the type of transmission assembly 40 employed, as long as the material strip can be moved back and forth within the mold, it is sufficient.

[0040] The equipment is also equipped with photoelectric sensors 90, which are respectively arranged at the entrances of the first feed port 201 and the second feed port 202. The photoelectric sensors 90 detect the feeding position of the material strip in real time and provide feedback signals to the PLC control system 60. When the pressure sensor 205 detects that the base 50 is not placed correctly, the PLC control system 60 pauses the drive device and triggers an alarm. The bottom mold assembly 20 and the upper mold assembly 80 adopt a modular design. The modules are connected by quick-release bolts 100, which facilitates the rapid replacement of grooves 204 and cutters 81 of different sizes to accommodate various touch switch models. For example, when switching to a small switch, the depth of the groove 204 is adjusted to 3 mm, and the cutter 81 is replaced with a narrow-blade blade; when switching to a large switch, the depth of the groove 204 is increased to 5 mm, and the cutter 81 uses a wide-blade blade.

[0041] During operation, the second material belt 32 transports the base 50 to the groove 204 of the assembly area 203, where the magnetic positioning block 206 attracts the base 50 to secure it. The first material belt 31 transports the assembly 51 directly above the base 50. Driven by the servo motor 71, the upper mold assembly 80 presses down, and the assembly 51 is precisely inserted into the base 50. Simultaneously, the cutter 81 cuts the connecting belt 52 to complete the separation. The synchronous belt 42 of the transmission assembly 40 pulls the material belt in the opposite direction as the upper mold assembly 80 rises, allowing the next set of bases 50 and assemblies 51 to enter the work station. The coordination of the guide groove 33 and the guide rail 208 ensures that the material belt moves without deviation. The photoelectric sensor 90 monitors the material belt position deviation in real time and automatically corrects the speed of the tug 41 of the transmission assembly 40 if the deviation exceeds the threshold.

[0042] In this embodiment, the anti-wear coating is made of titanium nitride with a thickness of 0.1 mm, significantly reducing frictional losses between the bottom die assembly 20 and the material strip. The pressure sensor 205 is a piezoelectric sensor with a sensitivity of 0.05 Newtons, capable of detecting minute pressure changes. The PLC control system 60 integrates a human-machine interface, allowing operators to set parameters such as cutting frequency and material strip speed and monitor equipment operating status in real time. The modular quick-release bolts feature a hexagonal design, allowing removal in under 30 seconds, significantly improving equipment maintenance efficiency.

[0043] Furthermore, the cylinder stroke of the pneumatic drive unit is adjustable from 5 to 20 mm to accommodate different belt cutting requirements. The pulley 41 has a module of 0.5 and 24 teeth, ensuring smooth transmission of the timing belt 42. The encoder resolution of the servo motor 71 reaches 0.01 degrees. Combined with the lever ratio design of the connecting rod mechanism, the downward pressure accuracy of the upper mold assembly 80 is controlled within ±0.02 mm. The magnetic induction strength of the magnetic positioning block is 0.8 Tesla, which not only firmly fixes the base but also facilitates the removal of the finished product by the robot.

[0044] Through the above design, the equipment realizes high-precision and high-efficiency automated assembly of touch switches. It also has strong adaptability and easy maintenance, and can be widely used in the field of electronic component manufacturing.

[0045] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements made to the technical solution of the present invention by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content for which protection is sought in the present invention is fully set forth in the claims.
