Description
TECHNICAL FIELD OF THE INVENTION
The present invention relates to remote control signal receiving module and manufacture method thereof, this novel receiver module can be blocked the infrared signal that external machine is launched, prevent the wrong identification of receiver module, enlarge the receiving angle of signal, improve receiving efficiency, shielding construction is located at the outside, can reduce the substandard product that occurs in the manufacture process, simplified manufacturing technique is enhanced productivity.
Background technology
The electric equipment that generally uses a teleswitch is a remote controller output output infrared signal, and the remote control signal receiving module identification signal of machine body inside also drives electrical equipment.
The receiver module of this remote signal causes wrong identification in order to prevent the infrared ray that bulb, fluorescent lamp etc. send, and materials such as the plastics of use conductivity, sheet metal form screened film.
In order to receive the remote signal of remote controller output, at the central opening of electromagnetic wave screening structure, modular assembly has formed an eyeglass position again.
Simultaneously, should consider the influence to the reception degree of remote signal of shielding electromagnetic waves structure and position during design, this has just increased fabrication, so remote control signal receiving module has accounted for bigger proportion aspect manufacturing process.
Fig. 1 is the exemplary of above-mentioned remote control signal receiving module to Fig. 4 b.
Fig. 1 is a Carrier to the label T among Fig. 4 b, and V is the shielding position, and H2 is a semiconductor device, U1, U2 are connecting portions, and E cuts off the position, S1, S2 is a sideway stance, and VG is a moulded portion, and P1-P5 is a guide terminal, M is an earth terminal, F is a window, the 1st, and ground connection, the 2nd, eyeglass position, the 3rd, side, the 4th, stator.
Remote control signal receiving module in the past illustrated in figures 1 and 2 is according to No. the 207356th, the domestic patent of Korea S, receives with the earth terminal M of main body frame, and all structures form so that epoxy is molded; Be connecting portion U1, the U2 bending, shielding part is displaced to the upside of Carrier T, be used for blocking external electromagnetic wave, cut off position E and sideway stance U1, U2 because screened film moves to the upside of Carrier T, the electromagnetic wave crooked once more, that the blocking-up side takes place is fixed on component internal to Carrier T and screened film V with epoxy.
Such remote control signal receiving module receives the signal of remote control output output, collects through the eyeglass of assembly, and by shielding the light receiving device spare that position V and window F pass to receiver module, just can its main body electrical equipment of remote control with this receiver module.
And for example shown in Fig. 3 and Fig. 4 a, Fig. 4 b, remote control signal receiving module in the past is that to be separated with main body frame and receiver module be feature, and the shielding construction upper end prolongs and forms ground connection position 1, its concavity, above-mentioned shielding construction blocking-up electromagnetic wave, and a static that produces is exported to external ground; Eyeglass 2 is that two frameworks of certain width are connected on central authorities mutually, and protrudes to flexure plane, fixedly the eyeglass of remote control signal receiving module; Side 3 prolongs from the central authorities of shielding construction, is close to the side of remote control signal receiving module, the electromagnetic wave of blocking-up side; Stator 4 is back that 3 prolongations from the side are fixed on remote control signal receiving module, and shielding construction is fixed on the receiver module.
Above-mentioned remote control signal receiving module is that main body frame and shielding construction are separated, so after the remote control signal receiving module assembly forms on the technology, the eyeglass of receiver module at first is installed on the eyeglass position 2 of shielding construction, with ground connection position 1, upper end and side 3 bendings, make shielding construction be close to receiver module, above-mentioned side 3 prolonged form stators 4, and bending is fixed on the side 3 of receiver module, once more the stator bending is fixed on the back of receiver module.
But according to No. the 207856th, the domestic patent of Korea S, the shielding construction of remote control signal receiving module is in inside, limited the angle that received signal that the eyeglass of assembly collects passes to the receipts optical transistor of module, reduced acceptance rate; If improving acceptance rate increases than receiving the wide window of optical transistor at shielding construction, then reduced the shielding electromagnetic waves rate, the identification that makes a mistake again and again, and also shielding construction is in the inside of assembly, so the resin flows resistance of liquid state increases greatly during moulding, cause that the resin filling is bad.
And for example, Fig. 3, other remote control signal receiving modules shown in Fig. 4 a and Fig. 4 b are that main body frame and shielding construction are separated, so after the receiver module assembly forms, again shielding construction is connected with receiver module, has increased manufacturing step, reduce efficient, increased cost.
Summary of the invention
Problem according to the conventional art existence, the objective of the invention is to: form the shielding construction that unites two into one with main body frame in the main body frame outside, on the shielding construction that is exposed eyeglass is installed, improve the acceptance rate of remote signal, prevent wrong identification, simplified manufacturing technique finally provides the remote control signal receiving module and the manufacture method thereof that have improved production efficiency.
According to above-mentioned purpose, the invention provides a kind of remote control signal receiving module, it is characterized in that a plurality of earth terminals are connected with main body frame downwards, central authorities form veneer at downside, and form the semiconductor Chip Area; Form moulded portion for protection device with the epoxy moulding in the outside, Chip Area; The upper end central perforation of veneer moulded portion, and the veneer moulded portion links to each other with connecting portion, and connecting portion is crooked also to surround the outside of moulded portion, like this, forms shielding construction; These shielding construction central authorities form lens hole, with fixing hemispherical eyeglass; Shielding construction is crooked and surround the moulded portion lower end, and the shielding construction upside forms pastes the position, fixes with the veneer of Chip Area.
The present invention also provides a kind of manufacture method of remote control signal receiving module, wherein, a plurality of earth terminals are connected with the Chip Area downwards with main body frame, the upside of Chip Area is linked to each other with connecting portion, thereby formation shielding construction, this shielding construction central authorities form lens hole, insert therein and fixing len, are connected to form the band steel Chip Area conductive adhesive stationary semiconductor devices of Chip Area at shielding construction upside and veneer; Described method may further comprise the steps: with the stickup step of conductive metal wire strip connector spare and main body frame; Molten synthetic resin and press certain thickness in the forming step of the good Chip Area injection mo(u)lding of welding and the hardening of resin step of the sclerosis of the assembly after the moulding under 140-150 degree high temperature with mould;
And described method is further comprising the steps of: the connecting portion behind the hardening of resin is crooked and surround semiconductor module and form blocking-up shielding electromagnetic waves step, and the stickup position of the upside of bending shielding construction also is welded to the welding step of main body frame.
