Description

Technical Field

[0001] This utility model relates to the field of lens welding technology, and in particular to a lens ICR welding fixture. Background Technology

[0002] In optical lenses, an ICR (Integrated Filter Switcher) is indispensable. The ICR is primarily used in infrared camera accessories to switch filters between infrared-sensitive and non-infrared filters during the day and infrared filters at night. Currently, the common method for mounting an ICR on an optical lens is to solder the ICR's wires onto FPC (Flexible Printed Circuit) material, connect the FPC material to various electronic components, and then lock it onto the lens. This allows for filter switching and the operation of other electronic components when the lens is powered on. However, current ICR soldering methods cannot securely fix the lens, and the fixtures are only suitable for single lenses, not different lens models. Utility Model Content

[0003] The purpose of this utility model is to provide a lens ICR welding fixture to fix the lens during ICR welding, which is applicable to different lens models.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0040] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0041] like Figures 1-9 As shown, the lens ICR welding fixture in this embodiment includes a base 10, a mounting base 20, a locking assembly 30, and a fixing assembly 40. Optionally, the mounting base 20 is detachably connected to the base 10 to allow for replacement of the mounting base 20 to accommodate different lens models 100, thus expanding its applicability. Furthermore, this embodiment of the lens ICR welding fixture is provided with multiple mounting bases 20 corresponding one-to-one with different lens models 100, and any one of the mounting bases 20 is detachably connected to the base 10. This allows for the positioning and installation of various lens models 100, expanding its application range and ensuring the stability of subsequent welding operations. Specifically, the mounting base 20 has an installation space to limit the position of the lens 100 and prevent it from moving during the welding process.

[0042] like Figures 1-3 As shown, in this embodiment, the length direction of the base 10 is set as the first direction, the width direction as the second direction, and the height direction as the third direction, and each of the three directions is perpendicular to the other. Optionally, in this embodiment, the locking component 30 is slidably disposed on the base 10 along the first direction, and the height of the locking component 30 relative to the mounting base 20 is adjustable. One end of the locking component 30 extends into the mounting space, and the locking component 30 can move along the first direction toward the mounting space to clamp the lens 100, or move away from the mounting space to release the lens 100. In this way, with the cooperation of the mounting base 20 and the locking component 30, the lenses 100 of various models are stably placed in the lens ICR welding fixture, which facilitates subsequent welding operations.

[0043] For example, in this embodiment, the fixing component 40 passes through and connects the locking component 30 and the base 10 in sequence, thereby ensuring the stable movement of the locking component 30 on the base 10. Further, in this embodiment, the lens ICR welding fixture is also provided with an adjusting shim for adjusting the height of the locking component 30. Specifically, the adjusting shim is detachably disposed between the locking component 30 and the base 10, and the fixing component 40 passes through the base 10, the adjusting shim, and the locking component 30 in sequence to connect the locking component 30, the adjusting shim, and the base 10. Specifically, the height of the locking component 30 can be adjusted by adjusting the number of stacked adjusting shims or by changing the thickness of a single adjusting shim.

[0044] Exemplarily, the bottom of the lens 100 is sequentially provided with a first protruding region, a side protrusion 140, a waist portion 110, a second protruding region, and an end portion 120 along a second direction. Specifically, the first protruding region is provided with a first protrusion 131, a second protrusion 132, and a third protrusion 133, and the second protruding region is provided with a raised strip 151 and a fourth protrusion 152. Further, the side of the end portion 120 opposite to the waist portion 110 can be connected to the protective housing 200 to protect the lens 100. Exemplarily, the top of the lens 100 is provided with a welding station 300 for welding.

[0045] like Figures 4-8 As shown, in this embodiment, the base 10 includes a mounting portion 11 and a limiting portion 12. The mounting base 20 is detachably connected to the mounting portion 11, and the locking component 30 is connected to the limiting portion 12, thereby ensuring the stable installation of the mounting base 20 and the locking component 30 on the base 10. Exemplarily, the mounting portion 11 and the limiting portion 12 are an integrated structure, thereby ensuring the stability of the base 10 and preventing the lens ICR welding fixture from shaking when adjusting the position of the locking component 30. Further, the height of the limiting portion 12 along a third direction is higher than the height of the mounting portion 11, thereby ensuring that the locking component 30 can tightly press against the side of the lens 100. Exemplarily, in this embodiment, the base 10 is configured as a weight-adding base to improve the overall stability of the lens ICR welding fixture.

[0046] like Figure 7 As shown, the mounting part 11 is further provided with a plurality of first mounting holes 111 for connecting the mounting base 20. In this embodiment, two first mounting holes 111 are spaced apart along the first direction. In other embodiments, their number and position can be set as needed, and no limitation is made here. Figure 8As shown, the limiting part 12 is provided with a limiting elongated hole 121, which extends along the first direction. The fixing component 40 passes through the limiting elongated hole 121 along the third direction and connects to the locking component 30. The fixing component 40 can move along the length direction of the limiting elongated hole 121, that is, the first direction, and can be locked at any position of the limiting elongated hole 121, thereby locking the locking component 30 and the base 10.

[0047] For example, two limiting elongated holes 121 are provided and arranged parallel to each other. Both limiting elongated holes 121 are arranged along the first direction, thereby enabling the locking component 30 to move along the first direction to approach or move away from the lens 100, thereby pressing against the side of the lens 100 or releasing the pressure on the lens 100, facilitating the removal and placement of the lens 100. Optionally, each limiting elongated hole 121 is provided with two sets of fixing components 40 to ensure the smooth and stable movement of the locking component 30. For example, the limiting elongated hole 121 is set as a T-shaped hole to limit the fixing component 40 and prevent the fixing component 40 from disengaging from the limiting elongated hole 121 during the movement of the locking component 30.

[0048] Combination Figures 4-6 As shown, in this embodiment, the mounting base 20 is provided with a first support platform 21 and a second support platform 22 spaced apart along the second direction. The waist 110 of the lens 100 is mounted on the first support platform 21, and the end 120 of the lens 100 is mounted on the second support platform 22. This ensures the stable placement of the lens 100 in the lens ICR welding fixture under the support of the first support platform 21 and the second support platform 22. Exemplarily, in other embodiments, the first direction may be set at an angle to the second direction, not limited to being perpendicular to the second direction. This allows for adjustment of the positions of the first support platform 21 and the second support platform 22, applicable to different models of the lens 100. The specific direction and position can be set as needed, and will not be elaborated here.

[0049] Furthermore, the mounting base 20 is provided with a first support block 23 and a second support block 24 spaced apart along the second direction and on the side opposite to the locking assembly 30. The first support block 23 is connected to the first support platform 21, and the second support block 24 is connected to the second support platform 22. Specifically, the first support block 23 is located on the side of the first support platform 21 opposite to the locking assembly 30, and the second support block 24 is located on the side of the second support platform 22 opposite to the locking assembly 30. The locking assembly 30 is used to abut the lens 100 against the first support block 23 and the second support block 24 to achieve stable positioning of the lens 100 in the lens ICR welding fixture. Specifically, the first support platform 21, the second support platform 22, the first support block 23, and the second support block 24 enclose the aforementioned mounting space to limit and fix the lens 100.

[0050] Furthermore, both the first support platform 21 and the first support block 23 are provided with clearance grooves to avoid protrusions of the lens 100. Specifically, the first support platform 21 is provided with a first clearance groove 211 to avoid the first protrusion 131, a second clearance groove 212 to avoid the second protrusion 132, and a third clearance groove 213 to avoid the third protrusion 133. Correspondingly, the first support block 23 is provided with a fourth clearance groove 231 to avoid the side protrusion 140, thus preventing interference during the installation of the lens 100.

[0051] Optionally, the gap between the first support platform 21 and the second support platform 22 is a clearance channel 201, and a clearance opening 202 is formed between the first support block 23 and the second support block 24 along the first direction. The clearance channel 201 and the clearance opening 202 are interconnected to avoid the protrusion 151 of the lens 100 and the fourth protrusion 152 provided on the protrusion 151, so as to avoid interference during the installation of the lens 100. Specifically, the clearance opening 202 is interconnected with the fourth clearance groove 231.

[0052] Optionally, a first receiving groove 221 and a second receiving groove 222 are provided through the second support platform 22 along the second direction. Specifically, the first receiving groove 221 is correspondingly provided to the end 120 and is used to receive the end 120 and provide support. Correspondingly, the second receiving groove 222 is correspondingly provided to the protective shell 200 and is used to receive the protective shell 200 and provide support. Further, two second mounting holes 203 are provided at the bottom of the clearance channel 201 along the first direction, and the second mounting holes 203 are corresponding one-to-one with the first mounting holes 111. After the fastener passes through the second mounting holes 203 and the first mounting holes 111 in sequence, the mounting base 20 can be fixed to the base 10. For example, the second mounting holes 203 are countersunk holes, so that the head of the fastener can be embedded inside the mounting base 20 without extending into the clearance channel 201 and interfering with the lens 100.

[0053] like Figure 9 As shown, in this embodiment, the locking assembly 30 includes a sliding seat 31 and a holding rod 32. The holding rod 32 is disposed on the sliding seat 31, and its two ends are an operating end 321 and a holding end 322, respectively. Specifically, the sliding seat 31 is slidably disposed on the base 10 along a first direction. Under the drive of the force, the operating end 321 drives the locking assembly 30 to move on the base 10 to approach or move away from the lens 100. The holding end 322 can extend into the installation space and abut against the side of the lens 100 to fix it. Optionally, in this embodiment, the sliding seat 31 and the holding rod 32 are an integrated structure to ensure the stability of the locking assembly 30. In other embodiments, the sliding seat 31 and the holding rod 32 can also be disposed separately, which is not limited here.

[0054] Specifically, the sliding seat 31 includes a mounting plate 311 and a seat body 312, with the seat body 312 fixed to the mounting plate 311 and the abutment rod 32 connected to the seat body 312. Optionally, the mounting plate 311 is provided with a plurality of fixing holes 3111, each corresponding to a fixing component 40 for connection to the fixing component 40. Exemplarily, the mounting plate 311 extends along the second direction on both sides of the seat body 312, and fixing holes 3111 are provided through the extended area. Exemplarily, the seat body 312 is provided with two fixing holes 3111 on one side along the second direction to allow two fixing components 40 to pass through, ensuring stable installation of the locking component 30 on the base 10.

[0055] Furthermore, the abutment rod 32 extends along the first direction on both sides of the base 312, and the operating end 321 is disposed on the sliding seat 31 at the end opposite to the mounting base 20, while the abutment end 322 is disposed on the sliding seat 31 at the end facing the mounting base 20. Specifically, the operating end 321 is used to drive the locking assembly 30 to move on the base 10, thereby moving closer to or away from the lens 100, stably pressing or releasing the lens 100, facilitating the removal, placement, and welding of the lens 100. Furthermore, the abutment end 322 can abut against the side of the lens 100, and the side of the abutment end 322 facing the lens 100 is set as a plane to ensure stable contact with the side of the lens 100.

[0056] like Figure 8 As shown, in this embodiment, the fixing component 40 includes a limiting member 41 and a locking member 42. The limiting member 41 is provided with a limiting elongated hole 121, an adjusting shim, and a locking component 30 in sequence to connect the locking component 30, the adjusting shim, and the base 10. The locking member 42 is screwed to the top of the limiting member 41 and abuts against the mounting plate 311 of the locking component 30 to ensure a stable connection between the limiting member 41 and the locking component 30.

[0057] Optionally, the limiting member 41 includes a connecting portion 411 and a limiting head 412, with one end of the connecting portion 411 extending into the base 10 connected to the limiting head 412 and the other end connected to the locking member 42. Specifically, the outer diameter of the limiting head 412 is larger than the outer diameter of the connecting portion 411 to form a T-shaped structure, which is confined in the T-shaped limiting elongated hole 121, so that the limiting member 41 cannot disengage from the limiting elongated hole 121 while still being able to move smoothly within the limiting elongated hole 121. Exemplarily, the connecting portion 411 and the limiting head 412 are configured as an integrated structure to improve the mechanical strength of the limiting member 41.
