Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor device equipment, in particular to a lithium tantalate pyroelectric detector. Background Art

[0002] When some crystals are heated, charges of equal quantity but opposite signs will be generated at both ends of the crystal. This polarization phenomenon caused by thermal changes is called the pyroelectric effect. Usually, the bound charges generated by the spontaneous polarization of the crystal are neutralized by free electrons from the air attached to the surface of the crystal, and its spontaneous polarization moment cannot be manifested. When the temperature changes, the center of gravity of the positive and negative charges in the crystal structure shifts relative to each other, the spontaneous polarization changes, and charge depletion will occur on the crystal surface. The charge depletion condition is proportional to the degree of polarization.

[0003] However, the existing technology has the following shortcomings: the current pyroelectric detector uses a tube cap as a covering part and is installed by bolts. However, the above installation method not only interferes with maintenance to a certain extent, but also makes the operation steps cumbersome and complicated. At the same time, when light passes through the filter in the center of the tube cap, it will form a visible area and a blind area with alternating light and dark. As a result, when the pyroelectric detector captures the heat source, the temperature capture range of the sensor surface is narrow, which in turn causes the pyroelectric detector to have a low sensitivity. Summary of the Invention

[0004] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained through the structures particularly pointed out in the description and other drawings.

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a lithium tantalate pyroelectric detector, which forms a hemispherical shape through the cooperation of the semi-conductive cover above the sleeve and its flip-up cap, and then refracts the heat source temperature capture range under the filter installed above, thereby indirectly improving the sensitivity of the pyroelectric detector. At the same time, the flip-up cap changes the traditional covering method during maintenance, making maintenance more convenient.

[0006] To achieve the above-mentioned objectives, the present invention is implemented through the following technical solutions: a lithium tantalate pyroelectric detector, comprising a detector tube base, a diffusion cover provided on the detector tube base, a plurality of reinforcing locks mounted on the diffusion cover, a sleeve provided within the diffusion cover, a flip cap nested within the sleeve, an integrated semi-conductive cover provided on the sleeve, a plurality of fixing blocks mounted on the inner wall of the sleeve, and a plurality of connection holes formed on the surface of the sleeve; a frame provided within the flip cap, a refractive cap shell connected to the frame, a plurality of filters disposed on the refractive cap shell, and flip assemblies mounted on both sides of the refractive cap shell. The refractive cap shell primarily refracts light to expand the detection area of ​​the filter, thereby correspondingly expanding and improving the sensitivity and range of the capture.

[0007] In a further improvement to the present invention, a connecting block is provided within the flip assembly, a through-groove being installed in the center of the connecting block, a plurality of latches being installed within the through-groove, a plug-in post extending through the through-groove, a pad being provided at the end of the plug-in post, and a recessed slot for the auxiliary feed strip being provided on the surface of the plug-in post. The latches primarily secure the plug-in post, allowing the plug-in post on the mating pad to swing in conjunction with the sleeve, allowing it to be opened directly for maintenance, eliminating the cumbersome maintenance steps.

[0008] The present invention is further improved in that the connecting blocks are fixed to both sides of the frame, the plug posts engage with the snap buttons via the recessed slots, the outer surface of the pads nests with the inner wall of the sleeve, the optical filter provided on the semi-conductive cover is identical to that provided on the refractive cap shell, the sleeve is hingedly connected to the flip cap, the semi-conductive cover cooperates with the flip cap, the sleeve nests within the surface of the detector tube base, and the reinforced locking member connects to the connecting hole. The semi-conductive cover and flip cap cooperate to form a semi-spherical shape, which refracts light passing through the interior of the refractive cap shell and cooperates with the optical filter, thereby alternatingly conducting the captured infrared light, causing the surface temperature of the sensing element to continuously change, thereby outputting an electrical signal.

[0009] In a further improvement of the present invention, the reinforcement lock is provided with a plurality of swinging frames, each of which is mounted with a transmission rod, each of which has a transmission cap at its top, and a clamping rod connected between the transmission rods. The clamping rod is primarily used to reinforce the diffuser cover and the detector tube base, so that they can be locked and fixed after installation, thereby ensuring a tight connection between the two.

[0010] In a further improvement to the present invention, a pendulum block is disposed within the swing frame, the pendulum block having a rotation hole formed therein, a plug hole disposed below the rotation hole, and a buckling post mounted on the pendulum block. The pendulum block is primarily used to adjust its angle during use, thereby better adapting the engagement position of the diffuser cover and the detector tube socket.

[0011] The present invention is further improved in that a column is provided inside the buckling column, a plurality of chutes are provided on the surface of the column, a pressure block is installed in the chutes at the plurality of locations, the end of the pressure block is connected to a lifting platform, a diffusion undercut bolt is installed on the lifting platform, and an inner support frame is installed in the center of the column. The diffusion undercut bolt mainly changes its initial state by being able to correspondingly break away from the limit between the columns after being lifted, thereby changing its swing to form a hook to complete the installation of the pendulum block.

[0012] In a further improvement to the present invention, the lifting platform is mounted within the inner support frame, the column is threadedly connected to the center of the inner surface of the swing block, the diffusion undercut is fixed to the inner wall of the semi-conductor cover, the pressure column extends through the connection hole, the transmission cap is connected to the outside of the swing frame, one end of the transmission rod is connected to the rotation hole, and the other end of the transmission rod is connected to the insertion hole, and the clamping rod is engaged below the detector tube seat. The column is displaced downward by pressure generated by a sliding groove on its surface, thereby exerting downward pressure on the lifting platform during the displacement process, thereby pushing the diffusion undercut out of the confinement of the column.

[0013] A further improvement of the present invention is that the detector tube base is provided with a heat sink, with several pins connected to the bottom of the heat sink, an embedded circuit board mounted on the heat sink, and a sensing element mounted above the embedded circuit board. The heat sink is provided with a disk body, and a plurality of arc baffles are mounted on the disk body. The disk body surface has bolt holes, and the inner wall of the arc baffle has an inner groove, and the inner groove is provided with a through-hole air guide hole. The arc baffles are placed with a gap between them, and the gap is just right for the fixing block to snap into. When the fixing block is matched, the bolt is locked into the bolt hole, thereby completing the connection between the diffusion cover and the detector tube base.

[0014] In a further improvement to the present invention, the sensing element comprises a silicon block, silicon dioxide is disposed above the silicon block, a gold sheet is disposed within the silicon dioxide, a lithium tantalate film is disposed above the gold sheet, and a plurality of detection units are mounted on the lithium tantalate film, with a plurality of thermal insulation grooves provided between the detection units. The thermal insulation grooves facilitate heat dissipation after induced heat generation, thereby preventing the influence or interference of heat source accumulation, which may cause a corresponding decrease in signal amplitude and a reduction in detection sensitivity.

[0015] The present invention is further improved in that the thermal insulation groove penetrates the lithium tantalate film, the silicon dioxide, the gold sheet, and the silicon block. The sensing element cooperates with the embedded circuit board, which cooperates with the pins. The air guide hole extends through the disk body, which is nested with the sleeve via the arc baffle. The fixing block on the inner wall of the sleeve is bolted to the bolt hole. The air guide hole is provided in the internal slot and extends through the disk body. It is primarily used to guide the internal heat source of the diffuser cover after it is connected to the disk body, preventing heat from accumulating between the diffuser cover and the disk body and adversely affecting the detection effect. Beneficial effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention forms a semi-spherical shape through the integrated structure of the semi-conductive cover above the sleeve and the flip cap. The filter installed above cooperates with the refractive cap shell to significantly improve the heat source temperature capture range. At the same time, the refractive cap shell can be flipped by the cooperation of the flip assembly and retracted into the semi-conductive cover for storage, changing the traditional pipe cap design and making maintenance more convenient.

[0018] 2. The present invention passes its swing frame through the connecting holes on the sleeve respectively, and then cooperates with the transmission rod and the rotating cap to connect the fixing rod. After the diffusion cover is installed, it is swung accordingly, so that the fixing rod is engaged under the detector tube seat, thereby achieving tightness when the detector tube seat and the diffusion cover are connected.

[0019] 3. The present invention separates the heat of the sensing element by the heat insulation groove opened on the original element, forming a rapid heat conduction after use. At the same time, the air guide holes in the grooves on the inner wall of the arc baffle fixed above the disc body guide the heat generated by the sensing element and discharge it from the bottom of the disc body, avoiding the problem of corresponding reduction in signal amplitude due to the influence or interference of heat source accumulation.

[0035] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0036] As attached Figure 1 To the attached Figure 4 As shown:

[0037] This embodiment provides a lithium tantalate pyroelectric detector, comprising a detector base 1, a diffusion cover 2 mounted on the detector base 1, a plurality of reinforced locking members 3 mounted on the diffusion cover 2, a sleeve 21 mounted within the diffusion cover 2, a flip cap 24 nested within the sleeve 21, an integrated semi-conductive cover 22 mounted on the sleeve 21, a plurality of fixing blocks 25 mounted on the inner wall of the sleeve 21, and a plurality of connection holes 23 formed on the surface of the sleeve 21. A frame 241 is mounted within the flip cap 24, a refractive cap shell 242 connected to the frame 241, a plurality of filters 243 mounted on the refractive cap shell 242, and flip assemblies 244 mounted on both sides of the refractive cap shell 242. A connecting block 2441 is provided in the flip assembly 244, a through slot 2442 is installed in the center of the connecting block 2441, a plurality of buttons 2443 are installed in the through slot 2442, a plug-in column 2445 passes through the through slot 2442, a pad 2444 is provided at the end of the plug-in column 2445, and an auxiliary feed strip concave slot 2446 is provided on the surface of the plug-in column 2445.

[0038] Furthermore, the semi-conductive cover 22 and the refractive cap shell 242 are both made of polyethylene plastic injection molding, and are milky white in color. The combined appearance forms a hemispherical shape, which is then used in conjunction with the optical filters 243 evenly distributed on the surface.

[0039] Furthermore, the filter 243 has a hexagonal appearance, but the appearance is not limited to hexagonal, and can also be square, rectangular, quadrilateral or circular, and is embedded in the cap shell 242 and the semi-conductive cover 22 by an operation method of equal distribution.

[0040] Furthermore, the frame 241 is used to mount the refractive cap shell 242 and cooperates with the flip assemblies 244 installed at both ends to drive the refractive cap shell 242 to retract into the semi-conductive cover 22, thereby improving its convenience during maintenance.

[0041] The specific working principle is as follows:

[0042] The present invention connects the detector tube base 1 with the diffusion cover 2 and then reinforces it with a reinforcement lock 3. A sleeve 21 is provided in the diffusion cover 2. The semi-conductive cover 22 and the flip cap 24 of the integrated structure above the sleeve 21 cooperate to form a semi-spherical shape. At the same time, the connecting block 2241 can cooperate with the plug-in column 2445 to conduct the pad 2444, driving the formed flip assembly 244 to swing the frame 241, completing the contraction of the flip cap 24. The semi-conductive cover 22 and the refractive cap shell 242 are made of the same material and cooperate with the filter 243 to complete the absorption and refraction of infrared rays, and finally conduct them to the detector tube base 1 for signal output. Example 2

[0043] As attached Figure 5 To the attached Figure 7 As shown:

[0044] The reinforced lock 3 is provided with a plurality of swing frames 31, each of which is mounted with a transmission rod 32. A transmission cap 33 is mounted at the top of each transmission rod 32, and a clamping rod 34 is connected between the transmission rods 32. A swing block 311 is mounted within the swing frame 31. The swing block 311 has a rotation hole 312, below which is a plug hole 313. A pressure column 314 is mounted on the swing block 311. The pressure column 314 has a column 3141 mounted within it. A plurality of sliding grooves 3142 are formed on the surface of the column 3141, and a pressure block 3143 is mounted within each of these grooves. The end of the pressure block 3143 is connected to a lifting platform 3145, on which a diffusion undercut bolt 3146 is mounted. An internal support frame 3144 is mounted in the center of the column 3141.

[0045] Furthermore, the swing block 311 is made of stainless steel, which makes it light and can swing in cooperation with the clamping rod 34 and the pressing column 314, thereby driving the connected diffusion cover and the detector tube seat to be clamped.

[0046] Furthermore, the clamping rod 3446 is made of a steel bar and a rubber sleeve, and its two ends are respectively connected to different transmission rods 32 to form a connection, so as to swing with the swing frame, which can not only ensure the firmness of the clamping, but also prevent the accessories from being scratched and damaged.

[0047] The specific working principle is as follows:

[0048] The present invention is to pass the buckling column 314 on the swing block 311 in the swing frame 31 through the connecting hole, and then the pressure block 3143 in the slide groove 3142 on the column 3141 is pressed against the outer wall of the sleeve, and the lifting push platform 3145 on the internal support frame body 3144 is lifted accordingly, so that the diffusion buckle 3146 pushes the column 3141 to a limit and then hooks on the inner wall of the sleeve, and then cooperates with the transmission rod 32 connected to the rotating hole 312 and the plug-in hole 313 to drive the fixing rod 32 with the nested rotating cap 33 to engage with the lower surface of the detector tube seat, thereby forming a fastening of the diffusion cover and the detector tube seat. Example 3

[0049] As attached Figure 8 To the attached Figure 10 As shown:

[0050] The detector tube base 1 includes a heat sink 11, with several pins 14 connected to its lower side. An embedded circuit board 12 is mounted on the heat sink 11, and a sensing element 13 is mounted above the embedded circuit board 12. A disk 111 is mounted within the heat sink 11, with a plurality of arc baffles 112 mounted on the disk 111. Bolt holes 113 are defined on the surface of the disk 111, and internal slots 114 are defined within the inner walls of the arc baffles 112. These slots 114 have air guide holes 115 extending through them. A silicon block 136 is mounted within the sensing element 13, with silicon dioxide 134 disposed above it. A gold sheet 135 is embedded within the silicon dioxide 134, and a lithium tantalate film 131 is mounted above the gold sheet 135. Several detection units 132 are mounted on the lithium tantalate film 131, with several thermal insulation grooves 133 defining the gaps between the detection units 132.

[0051] Furthermore, at least four arc baffles 112 are installed on the disc body 111 to form a circular ring state, which is adapted and connected with its sleeve, and the fixing blocks between the sleeves are clamped and the bolt holes 113 thereof are corresponding.

[0052] Furthermore, the air guide hole 115 opened in the inner slot 114 penetrates the arc baffle 112 and then penetrates the disk body 111, so as to dissipate heat to the sensing element 13 after the sensing element 13 completes its work, thereby reducing heat accumulation.

[0053] Furthermore, the lithium tantalate film 131 can achieve the same performance as commercial lithium tantalate detectors by reducing the thickness of lithium tantalate and optimizing the packaging process of the diffusion cover 2, and has narrow-band detection capabilities that current commercial lithium tantalate detectors do not have.

[0054] The specific working principle is as follows:

[0055] The present invention absorbs infrared rays through the diffusion cover 2, which then irradiates the surface of the lithium tantalate film 131 and forms a heat energy conduction and detection unit 132 with the cooperation of the silicon dioxide 134 and the gold sheet 135 below, causing it to send a signal, which enters the embedded circuit board 12 in the heat dissipation carrier 11 and is detected and output by the pin 14. The heat generated by the sensing element 13 is isolated and dissipated by the heat insulation groove 133. At the same time, the air guide holes 115 in the inner groove 114 opened inside the arc baffle 112 on the disk body 111 also guide the heat source accordingly, and discharge it from the bottom of the disk body 111 to avoid the influence or interference of the signal operation due to the accumulation of the heat source. Example 4

[0056] As attached Figure 1 To the attached Figure 10 As shown: Figure 1 This is a schematic structural diagram of a lithium tantalate pyroelectric detector according to the present invention; Figure 2This is a schematic diagram of the three-dimensional structure of a diffusion cover in a lithium tantalate pyroelectric detector of the present invention; Figure 3 This is a schematic diagram of the three-dimensional structure of a flip cap in a lithium tantalate pyroelectric detector of the present invention; Figure 4 This is a schematic diagram of the exploded structure of a flip assembly in a lithium tantalate pyroelectric detector of the present invention; Figure 5 This is a schematic diagram of the three-dimensional structure of a reinforced lock member in a lithium tantalate pyroelectric detector according to the present invention; Figure 6 This is a schematic diagram of the three-dimensional structure of a swing frame in a lithium tantalate pyroelectric detector of the present invention; Figure 7 This is a schematic diagram of the internal structure of a buckling column in a lithium tantalate pyroelectric detector of the present invention; Figure 8 This is a schematic diagram of the three-dimensional structure of a detector tube holder in a lithium tantalate pyroelectric detector of the present invention; Figure 9 This is a schematic diagram of the three-dimensional structure of a heat dissipation carrier in a lithium tantalate pyroelectric detector of the present invention; Figure 10 The figure is a partial cross-sectional structural schematic diagram of a sensing element in a lithium tantalate pyroelectric detector of the present invention.

[0057] The specific working principle is as follows:

[0058] The present invention first connects the embedded circuit board 12 and the sensing element 13 on the heat dissipation carrier 11 in the detector tube seat 1, and then, with the cooperation of the arc baffle 112 on the disk body 111, the sleeve 21 in the diffusion cover 2 is fixed with the fixing block 25 and the interval thereof. The bolts screw the fixing block 25 and the bolt hole 113 to complete the fixing of the sleeve 21. Before use, the flip components 244 on both sides of the frame 241 are connected to each other so that the connecting block 2441 fixed to the side wall of the frame 241 receives the through hole 2445 of the plug-in column. After passing through the through slot 2442, the concave slot 2446 on the plug-in column 2445 is locked under the stroke of the button 2443 so that the refractive cap shell 242 can be hinged with the semi-conductive cover 22 to form a semi-spherical shape. Finally, the buckling column 314 on the swing block 311 in the swing frame 31 is respectively inserted into the corresponding connecting hole 23, and the top sleeve 21 surface of the pressing block 3143 on the column 3141 is displaced in the sliding groove 3142, completing the corresponding lifting of the lifting platform 3145 in the inner support frame body 3144. , when the diffusion buckle bolt 3146 passes through the column 3141 and forms a hook on the inner wall of the sleeve 21, the transmission rod 32 connected to the rotating hole 312 and the plug hole 313 on the auxiliary swing block 311 drives the clamping rod 34 connected to the bracket to engage with the bottom of the detector tube base 1, completing the reinforcement of the diffusion cover 2 and the detector tube base 1. Finally, the pin 14 is inserted into the designated position. The semi-spherical diffusion cover 2 absorbs the external infrared rays under the cooperation of the refractive cap shell 242 and the filter 243, and irradiates the lithium tantalate thin film after refraction. The surface of the membrane 131 generates heat with the cooperation of the gold sheet 135, silicon block 136 and silicon dioxide 134 below, forcing the detection unit 12 to generate a signal output. After being conducted to the embedded circuit board 12, the signal is output from the pin 14. After the output, the heat insulation groove 133 dissipates the heat from the internal structure of its sensing element 13. The inner groove opened on the inner wall of the arc baffle above the disk body 111 also guides the heat through the internal air guide hole 115 and releases it from the bottom of the disk body 111, avoiding the influence or interference of the signal operation due to the accumulation of heat sources.
