[0001] This utility model relates to the field of camera lens assembly technology, specifically, it demonstrates a camera lens assembly and pressing tooling and equipment. Background Technology

[0002] Camera modules typically have mounting slots on their front housings for mounting lenses.

[0003] Currently, lens installation into the mounting slot is primarily done manually. In the actual assembly process, workers manually pick up the lens, then initially fix it in the mounting slot, and finally press the front housing and lens together to complete the lens installation.

[0004] However, manual lens assembly is labor-intensive and has low assembly and pressing efficiency. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art. Therefore, the purpose of this utility model is to provide a camera lens assembly and pressing tool and equipment.

[0006] To achieve the above objectives, on one hand, the camera lens assembly and pressing fixture according to an embodiment of the present invention includes:

[0007] A carrier, on which clamps are provided for fixing the camera module to be assembled;

[0008] A pressing head is located above the carrier and can be adjusted up and down relative to the carrier via a pressing mechanism. The pressing mechanism includes a power group, a pressure detection group, and a buffer group connected in sequence, with the pressing head connected to the buffer group.

[0009] An adsorption head is connected to a pressing head, and the distal end of the adsorption head has an adsorption port that interacts with the lens being adsorbed.

[0010] In addition, the split-type heating and pressure-holding fixture table according to the above embodiments of this utility model may also have the following additional technical features:

[0011] According to one embodiment of the present invention, the adsorption head includes a main body and an adsorption body. The adsorption body has an air cavity communicating with the adsorption port inside. The main body has an air passage communicating with the air cavity inside. The air passage extends to one side of the main body and is provided with an air source connector for connecting a negative pressure air source.

[0012] Furthermore, the adsorption port is circular in shape.

[0013] Furthermore, a sealing gasket is provided on the bottom surface of the adsorbent, which is aligned with the center of the adsorption port.

[0014] According to one embodiment of the present invention, the power unit includes a drive component and a mounting base. The drive component is mounted on a side bracket and is used to drive the mounting base to reciprocate in a direction closer to or further away from the carrier. The mounting base is movably connected to the side bracket via a first slider rail.

[0015] Furthermore, a blocking post is provided on the lower outer wall of the side bracket, and the top of the blocking post can contact the bottom surface of the mounting base to limit the minimum displacement of the mounting base.

[0016] Furthermore, the pressure detection group includes a jacking body and an intermediate body. The jacking body is connected to the mounting base, and the intermediate body is movably connected to the jacking body through a second slider rail. A pressure sensor is provided at the bottom of the intermediate body, and a jacking rod with its lower end capable of contacting the pressure sensor is provided at the lower part of the jacking body.

[0017] Furthermore, the buffer assembly includes an upper body and a lower body. The upper body is connected to the intermediate body, and the lower body is connected to the upper body through several guide posts. The upper parts of the guide posts are movably inserted into the upper body, and the lower outer walls of the guide posts are fitted with spring members located between the upper and lower bodies.

[0018] According to one embodiment of the present invention, the top surface of the carrier is provided with a contour groove for placing the camera module to be assembled, and the clamp includes several elastic adjustment clamps distributed around the contour groove.

[0019] On the other hand, the pressing device according to the present invention includes a control housing and a camera lens assembly pressing fixture as described in the first aspect.

[0020] Compared with the prior art, the advantages of this utility model are as follows: the camera module to be assembled is placed stably on the carrier, and the lens is placed in the preset assembly position on the camera module to be assembled in the correct posture for pre-positioning. The pressing mechanism enables the pressing head and the suction head to approach the lens downward together. The suction head is used to adsorb and fix the lens to ensure the accuracy of the lens position during the pressing process.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The camera lens assembly and pressing tooling and equipment of this utility model embodiment are described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 4 As shown, the camera lens assembly and pressing fixture provided according to the embodiment of this utility model mainly includes a carrier 1, a pressing mechanism, a pressing head 3, and an adsorption head 7.

[0030] Specifically, the top surface of the carrier 1 is provided with a contour groove 11 for placing the camera module to be assembled. The contour groove 11 is designed to fit the shape of the camera module. The top surface of the carrier 1 is also provided with a clamp 2, which is close to the contour groove 11 and is used to fix the camera module to be assembled on the contour groove, so as to ensure that the camera module to be assembled maintains the correct position and posture during the test.

[0031] The pressing head 3 is designed above the carrier 1. Under the driving action of the pressing mechanism, the pressing head 3 can move up and down relative to the carrier 1. The pressing mechanism includes a power unit 4, a pressure detection unit 5, and a buffer unit 6 connected in sequence. The pressing head 3 is connected to the buffer unit 6. The power unit 4 is used to provide the driving force to drive the pressing head 3 to move up and down. The pressure detection unit 5 can be used to monitor the pressure parameters of the power unit 4 during the pressing process, thereby adjusting and maintaining the pressure level applied to the lens. The buffer unit 6 is used to absorb and disperse the excessive concentrated pressure during the pressing process, effectively avoiding local "hard pressure" that could damage the lens.

[0032] The adsorption head 7 is designed below the pressing head 3. It can move up and down relative to the carrier 1 together with the pressing head 3. The adsorption head 7 can contact the lens downwards. An adsorption port 71 is opened at the middle of the far end of the adsorption head 7, that is, the bottom end, so as to interact with the lens being adsorbed. A negative pressure can be formed near the adsorption port 71 to achieve the adsorption effect on the lens. The adsorption port is generally designed to be round, so as to better adapt to flat lenses. The adsorption head is mainly used to adsorb and fix the lens to ensure the accuracy of the lens position during the pressing process and prevent the lens position from shifting.

[0033] In one embodiment of this utility model, the adsorption head 7 includes a main body 72 and an adsorption body 73. The main body 72 is connected upward to the pressing head 3. The adsorption body 73 is disposed in the middle of the bottom end of the main body 72. An air cavity 74 communicating with the adsorption port 71 is opened inside the adsorption body 73. An air passage 75 communicating with the air cavity 74 is opened inside the main body 72. The air passage 75 extends to one side of the main body 72 and is provided with an air source connector 76 for connecting a negative pressure air source. After the negative pressure air source is connected, the air passage 75 and the air cavity 74 will form a negative pressure adsorption effect at the adsorption port 71, thereby realizing the adsorption and fixation of the lens.

[0034] To further ensure a tight adsorption of the lens, a sealing gasket 77 is provided on the bottom surface of the adsorption body 73. The sealing gasket 77 is also designed in a circular shape and its center is consistent with the center of the adsorption port 71. In addition to ensuring good airtightness of the adsorption, the sealing gasket can also protect the lens to a certain extent and prevent the adsorption body on the adsorption head from excessively damaging the lens itself.

[0035] In one embodiment of this utility model, the power unit 4 includes a drive member 41 and a mounting base 42. The drive member 41 is mounted on a side bracket 43 and is used to drive the mounting base 42 to reciprocate in the direction of approaching or moving away from the carrier 1. The drive member 41 is generally a cylinder, which provides a vertical lifting force to the mounting base. The mounting base 42 is movably connected to the side bracket 43 through a first slider rail 44, that is, the mounting base 42 can move up and down smoothly.

[0036] At least one blocking post 45 is provided on the lower outer wall of the side bracket 43. The top of the blocking post 45 can contact the bottom surface of the mounting base 42 to limit the minimum displacement of the mounting base 42, prevent the power unit from driving the mounting base downwards excessively, and form a stroke protection.

[0037] Based on the above scheme, the pressure detection group 5 includes a top moving body 51 and an intermediate body 52. ​​The top moving body 51 is connected upward to the mounting base 42, and the intermediate body 52 is movably connected to the top moving body 51 through a second slider rail 53. The slider is set on the intermediate body, and the rail is set on the top moving body. That is, the intermediate body 52 can slide up and down relative to the top moving body 51. The top moving body 51 also has a limiting pin 56 for limiting the slider on the intermediate body 52 to continue to move downward. That is, the limiting pin is located below the slider. A pressure sensor 54 is set at the bottom of the intermediate body 52, and a top moving rod 55 with its lower end able to contact the pressure sensor 54 is set at the lower part of the top moving body 51.

[0038] In the initial state, the slider on the intermediate body 52 is blocked by the limiting pin 56. At this time, the intermediate body 52 is at its lowest position relative to the top moving body 51, and the top moving rod 55 is not in contact with the pressure sensor 54. During the pressing process, the adsorption head 7 first contacts the lens, and then the intermediate body 52 and the top moving body 51 slide relative to each other. The top moving rod 55 on the top moving body 51 gradually contacts the pressure sensor 54 downward and continuously applies pressure until the pressure reaches the preset value.

[0039] Based on the above scheme, the design of the buffer group 6 includes an upper body 61 and a lower body 62 arranged in parallel. The upper body 61 is connected to the middle body 52, and the lower body 62 is connected to the upper body 61 through several guide posts 63. The upper part of the several guide posts 63 is movably inserted into the upper body 61, and the lower outer wall of the guide posts 63 is fitted with a spring member 64 located between the upper body 61 and the lower body 62. In this way, the pressure generated by the pressing mechanism will be transmitted to the lower body 62 through the spring member 64 to achieve flexible pressing and effectively avoid damage to the lens caused by the adsorption head locally "hard pressing" the lens.

[0040] In one embodiment of this utility model, the clamp 2 includes several elastically adjustable clamping blocks 21 distributed around the contour groove 11. These elastically adjustable clamping blocks 21 achieve an elastic clamping effect on the camera module to be assembled on the contour groove 11. Specifically, the surface of the carrier 1 is provided with a sliding groove 12 for the elastically adjustable clamping blocks 21 to slide and be fitted. A limiting rod 13 is provided on the sliding groove 12, and a waist hole 22 is provided in the elastically adjustable clamping block 21 for the limiting rod 13 to move laterally. The limiting rod 13 is fixed and its top end cannot be disengaged from the waist hole 22. A telescopic spring 23 is provided in the waist hole 22 with one end connected to the limiting rod 13. The telescopic spring 23 pushes the elastically adjustable clamping block 21 toward the camera module, and the head end of the elastically adjustable clamping block 21 achieves the pushing effect on the side of the camera module.

[0041] Reference Figure 5 As shown, according to another embodiment of the present invention, an assembly and pressing device includes a control housing 8 and a camera lens assembly and pressing fixture as described above. The control housing 8 can be equipped with an automated control system, which simplifies the testing process, improves work efficiency, and increases the degree of automation, thus having broad application prospects.

[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
