Problems solved by technology
However, such a manufacturing process requires a lot of manpower and time to assemble the components. In addition, because of the manual assembly, the volume of the photoelectric switch 10 cannot be too small, that is, if the transmitting component 14, the receiving component 16 and the If the size of the plastic housing 12 is too small, the operator cannot easily perform the assembly work
In addition, the plastic shell 12 of the traditional photoelectric switch 10 is used to provide suitable light-shielding function to avoid external light from affecting the operation of the photoelectric switch 10, so it is mostly a black shell, so the appearance color of the traditional photoelectric switch 10 cannot be arbitrarily Variety

[0028] Please also see image 3 and Figure 4 , image 3 For forming the schematic diagram of the required components of the photoelectric switch of the present invention, and Figure 4 for image 3 The enlarged schematic diagram of the die 46 , the transmitting unit 43 and the receiving unit 45 is shown. image 3 Shown in the figure is a transmitting component lead frame 32 , a receiving component lead frame 34 , a mold bar 36 and a mold bar 38 . The emitter assembly lead frame 32 includes a fixed chip, a plurality of emitter units 43 bonded by wires, a plurality of pairs of wires 42a, 42b, and two support bars (bars) 50a, 50b. Each pair of wires 42 a , 42 b is coupled to a corresponding emitting unit 43 , and a emitting unit 43 and the corresponding pair of wires 42 a , 42 b form a emitting component 55 . In addition, by virtue of the positioning function provided by the support rods 50a, 50b (details will be described later), the relative distance between the plurality...

The disclosed method for forming photoelectric switch includes following parts and steps: providing a molded granule including first groove and second groove; infilling filtering plastotype material to the first groove and the second groove; placing an emitting unit and a receiving unit into the plastotype material in the first groove and the second groove; solidifying the filtering plastotype material in order to fix the emitting unit and the receiving unit to the molded granule.
Description
technical field [0001] The invention provides a method for forming a photoelectric component, in particular a method for forming a photoelectric switch. Background technique [0002] see figure 1 and figure 2 , figure 1 Be the schematic diagram of the respective parts of traditional photoelectric switch 10, and figure 2 for figure 1 Schematic diagram of the parts shown after assembly. Such as figure 1 As shown, the photoelectric switch 10 includes a plastic casing 12 , a transmitting component 14 and a receiving component 16 . The transmitting unit 14 includes a transmitting unit 18 , a pair of wires 15 a, 15 b and a plastic casing 21 , while the receiving unit 16 includes a receiving unit 19 , a pair of wires 17 a, 17 b and a plastic casing 22 . The production of the traditional photoelectric switch 10 requires the operator to manually place the transmitting assembly 14 and the receiving assembly 16 into the plastic housing 12, which becomes figure 2 The finished...
