Technical Field

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

[0002] With the increasing popularity of motorcycle travel and growing safety awareness, motorcycle dashcams have become a common piece of equipment used to record riding footage, ensuring safety and providing evidence. The lens module, its core component, is crucial to image quality.

[0003] In the production and after-sales maintenance of dashcams, the assembly and disassembly of lens modules are common processes. For example, quality inspection is required on the production line, while after-sales maintenance requires removing the lens assembly for troubleshooting, repair, or replacement.

[0004] Currently, the industry commonly uses hydraulic drive for disassembling lens assemblies. This method usually relies on hydraulic equipment to push the lens assembly out of the adhesive interface of the housing using the force generated by hydraulic pressure. However, the hydraulic drive method is not only structurally complex, but also has high maintenance costs.

[0005] Based on this, in order to further optimize the convenience of existing lens modules, we propose a lens module disassembly fixture. Summary of the Invention

[0006] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the complex structure of hydraulic drive methods, and to propose a lens module disassembly fixture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a lens module disassembly fixture, including:

[0009] The base and the fixture assembly fixed to the base;

[0010] A vertical pole is fixedly installed above the base, and an adjusting seat is installed on the outside of the vertical pole. A pressure rod is movably connected inside the adjusting seat, and a driving assembly for driving the pressure rod to move downward is also installed inside the adjusting seat.

[0011] A pressure head assembly is detachably connected to the bottom of the pressure rod, and the pressure head assembly and the fixture assembly are positioned opposite each other.

[0012] Furthermore, the pressure rod and the adjusting seat are circumferentially locked;

[0013] A connecting rod is fixedly installed above the adjusting seat, and a tension spring is fixedly installed between the connecting rod and the pressure rod.

[0014] Furthermore, a rack portion is provided on the outer periphery of the pressure rod along the height direction;

[0015] The drive assembly includes a gear shaft rotatably connected inside the adjusting seat, the gear shaft meshing with the rack portion.

[0016] Furthermore, one end of the gear shaft extends to the outside of the adjusting seat and is fitted with a drive rod, the drive rod and the gear shaft being movably connected.

[0017] Furthermore, a number of positioning holes are spaced apart on the outer side of the drive rod, and a positioning rod is movably inserted into the side end of the gear shaft via a spring, with the end of the positioning rod inserted into the positioning hole.

[0018] Furthermore, a limiting seat is fixedly installed above the pressure rod, and a limiting screw is threadedly connected to the end face of the limiting seat. The top of the adjusting seat has a contact surface that stops the limiting screw.

[0019] Furthermore, the pressure head assembly includes a plug rod that is movably inserted into the bottom of the pressure rod, and an abutment head is fixedly installed at the bottom of the plug rod;

[0020] The pressure rod has a locking hole on its outer side that connects to its inner hole, and a spring plug is embedded on the outer side of the plug rod. The telescopic end of the spring plug is plugged into the locking hole.

[0021] Furthermore, the fixture assembly includes an adjusting base plate and an adjusting top plate. Both the adjusting base plate and the adjusting top plate have waist grooves on their end faces, and the adjusting top plate also has clamping holes on its end face.

[0023] Furthermore, the adjusting seat is slidably connected to the upright.

[0024] The lens module disassembly fixture proposed in this utility model has the following advantages: Firstly, the fixture uses a fixture assembly to position the recorder's housing. Then, a drive assembly controls the pressure rod to move downwards, causing the lens module to abut against and separate from the housing. This method is simple and convenient to operate, requires no hydraulic system, and has low maintenance costs. Secondly, the height of the adjustable seat is adjustable. In batch operations, the initial position of the pressure head assembly can be adjusted according to the height of different modules, thus reducing the ineffective control stroke of the drive rod and greatly improving disassembly efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-5 As one embodiment of this utility model, a lens module disassembly fixture is disclosed. Specifically, the general-purpose fixture includes a base 1 and a fixture assembly 2 fixed to the base 1.

[0033] A vertical rod 3 is fixedly installed above the base 1, and an adjusting seat 4 is installed on the outside of the vertical rod 3. The adjusting seat 4 is slidably connected to the vertical rod 3. A pressure rod 5 is movably connected inside the adjusting seat 4, and a driving assembly 6 that drives the pressure rod 5 to move downward is also installed inside the adjusting seat 4.

[0034] A pressure head assembly 7 is detachably connected to the bottom of the pressure rod 5, and the pressure head assembly 7 and the fixture assembly 2 are positioned vertically opposite each other.

[0035] When operating the lens module, first place the lens module in the jig assembly 2, then drive the drive assembly 6 to drive the pressure rod 5 to move down, so that the pressure head assembly 7 will push the lens module downward to detach it from the housing. This completes the disassembly of the lens assembly. After disassembly, take out the lens module for separation, and then repeat the filling and reloading operation.

[0036] In some embodiments, the pressure rod 5 and the adjusting seat 4 are circumferentially locked. Specifically, the locking method can be a combination of a sliding groove and a sliding block. This circumferential locking is used to prevent the pressure rod 5 from rotating circumferentially inside the adjusting seat 4.

[0037] A connecting rod 41 is fixedly installed above the adjusting seat 4. A tension spring 42 is fixedly installed between the connecting rod 41 and the pressure rod 5. The tension spring 42 is used to move the pressure rod 5 upward and reset it after the pressure rod 5 is pushed down.

[0038] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the outer periphery of the pressure rod 5 is provided with a rack portion 51 along the height direction. The drive assembly 6 includes a gear shaft 61 rotatably connected inside the adjusting seat 4. The gear shaft 61 meshes with the rack portion 51. One end of the gear shaft 61 extends to the outside of the adjusting seat 4 and is equipped with a drive rod 62.

[0039] Based on the above embodiments, in this embodiment the drive rod 62 and the gear shaft 61 are movably connected.

[0040] In other words, the length of the drive rod 62 described in this embodiment is adjustable. As those skilled in the art know, when the effective lever arm length of the drive rod 62 changes, its driving force will change accordingly. Therefore, in this embodiment, the length of the drive rod 62 can be adaptively adjusted according to the disassembly force requirements of different modules, thus satisfying the convenience and adaptability of disassembly.

[0041] like Figure 2 As shown, a plurality of positioning holes 63 are spaced apart on the outer side of the drive rod 62, and a positioning rod 65 is movably inserted into the side end of the gear shaft 61 through a spring 64, and the end of the positioning rod 65 is inserted into the positioning hole 63.

[0042] Specifically, when it is necessary to adjust the effective length of the drive rod 62, first pull the positioning rod 65 outward. In this embodiment, the two ends of the spring 64 are fixed to the positioning rod 65 and the gear shaft 61. When the positioning rod 65 moves outward, it will separate from the positioning hole 63 on the drive rod 62. At this time, the drive rod 62 can be movably inserted to adjust its length. After the adjustment is completed, the positioning rod 65 can be inserted into the corresponding positioning hole 63.

[0043] In some embodiments, a limiting seat 52 is also fixedly installed above the pressure rod 5, and a limiting screw 53 is threadedly connected to the end face of the limiting seat 52. The top of the adjusting seat 4 has an abutment surface 43 that stops the limiting screw 53.

[0044] Specifically, in this embodiment, the limiting screw 53 is used to control the downward pressure height of the pressure rod 5, so as to avoid the problem of the pressure rod 5 being pressed down too high, causing damage to the module.

[0045] Preferably, in this embodiment, a locking nut can be threaded onto the outside of the limiting screw 53 to lock the position of the limiting screw 53, so as to ensure the accuracy of its limiting height. In specific operation, when the pressure rod 5 is pressed down, when the bottom of the limiting screw 53 abuts against the contact surface 43 on the adjusting seat 4, the pressure rod 5 can no longer move down.

[0046] Furthermore, such as Figure 3 As shown, the pressure head assembly 7 in this embodiment includes a plug rod 71 that is movably inserted into the bottom of the pressure rod 5. A contact head 72 is fixedly installed at the bottom of the plug rod 71. Preferably, the contact head 72 in this embodiment can be set as a rubber block, the purpose of which is to achieve flexible contact with the lens module to avoid damage to the lens.

[0047] In this embodiment, considering the adaptation to different lens modules, the outer side of the pressure rod 5 is provided with a locking hole 73 that communicates with its inner hole, and the outer side of the plug rod 71 is fitted with a spring plug 74, the telescopic end of the spring plug 74 is plugged into the locking hole 73.

[0048] In other words, in this embodiment, when different lens modules need to be adapted, in order to ensure that the contact head 72 can contact the lens module inside the housing, the telescopic end of the spring plug 74 can be pushed inward to retract it. At this time, the plug rod 71 can be swung outward, and then the new pressure head assembly 7 can be replaced. The specific structure of the spring plug 74 is a conventional method for those skilled in the art, and will not be described in detail here.

[0049] In some embodiments, the fixture assembly 2 includes an adjusting base plate 21 and an adjusting top plate 22. A waist groove is provided on the end face of both the adjusting base plate 21 and the adjusting top plate 22, and a clamping hole 23 is also provided on the end face of the adjusting top plate 22.

[0050] Of course, in this embodiment, the waist groove on the adjusting base plate 21 and the waist groove on the adjusting top plate 22 are perpendicular. The adjusting base plate 21 is fixed to the base 1 by fasteners and the waist groove, and the adjusting top plate 22 is fixed to the adjusting base plate 21 by fasteners and the waist groove. In this way, during assembly, the planar position can be adjusted within a certain range to ensure that the clamping hole 23 is directly below the contact head 72.

[0051] Furthermore, the clamping hole 23 described in this embodiment can be circular, rectangular, or other shapes, specifically referring to the design of the dashcam's housing. During disassembly, the dashcam's housing is first placed in the clamping hole 23, and the driving component 6 drives the pressure rod 5 downward to drive the contact head 72 to push the lens module in the housing downward to detach it from the housing, thus completing the disassembly of the lens assembly. In addition, the adjusting top plate 22 and adjusting bottom plate 21 described in this embodiment are detachably connected, so different housing sizes can be adapted by replacing different adjusting top plates 22.

[0052] Based on the above embodiments, in order to adjust the initial height of the entire pressure rod 5, the adjusting seat 4 located on the outer part of the upright rod 3 is in the form of a C-shaped structure. The two ends of the C-shaped structure are locked and fixed by fasteners. The adjusting seat 4 and the upright rod 3 are circumferentially locked. Of course, the adjusting seat 4 and the upright rod 3 in this embodiment can also adopt a sliding fit of a groove and a slider.

[0053] Specifically, all the fasteners described in this embodiment can be set as bolts. With this adjustable structure design, the initial position of the pressure head assembly 7 can be adjusted according to the height of different modules during batch operations. This reduces the ineffective control stroke of the drive rod 62 and greatly improves the disassembly efficiency.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
