Description

Technical Field

[0001] The present invention relates to the field of focusing devices, in particular to a marking mechanism and a focusing device. Background Art

[0002] With the development of electronic technology, the demand for cameras on various electronic products, such as mobile phones and laptops, is increasing. The camera module needs to be focused before it is put into use. The focusing of the camera module is completed by a focusing machine. After focusing, the camera module has a better focal length and thus better shooting quality.

[0003] After the camera module has been focused by the focusing machine, it needs to be marked by a marking mechanism to facilitate subsequent identification and processing of the camera module. During the marking process, the sliding drive drives the marking part to move to the surface of the camera module, so that the marking part of the marking part contacts the surface of the camera module, and then leaves a mark on the surface of the camera module. However, when marking, the traditional marking mechanism is difficult to better control the contact stress between the marking part and the camera module, so that the contact stress between the marking part and the camera module is too large or too small. When the contact stress is too large, the camera module will be damaged due to excessive pressure. When the contact stress is too small, it will not be possible to leave a clear mark on the camera module. Therefore, it is necessary to improve the traditional marking mechanism. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a marking mechanism and focusing device that can better control the contact pressure between the marking part and the camera module, avoid damaging the camera module due to the marking price, and improve the marking clarity.

[0005] The object of the present invention is achieved through the following technical solutions:

[0014] In one embodiment, the second connecting member is provided with a sliding groove, and the first connecting member is slidably arranged in the sliding groove so that the first connecting member and the second connecting member are slidingly connected, and the two ends of the elastic member are respectively in contact with the groove wall of the sliding groove and the first connecting member.

[0015] In one embodiment, the elastic member is a coil spring or an elastic rubber member.

[0016] In one embodiment, the buffer connection assembly further includes a clamping member and a fixing member, the clamping member includes a first clamping portion and a second clamping portion, the first clamping portion is connected to the second connecting member, the fixing member is respectively connected to the first clamping portion and the second clamping portion, a clamping area is formed between the first clamping portion and the second clamping portion, the fixing member is used to adjust the size of the clamping area, and the marking member is interference-enhanced in the clamping area.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] After the marking part of the marking part contacts the camera module, the sliding drive part will continue to drive the first connecting part to move a shorter distance at one end.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figure 1 As shown, a marking mechanism 10 according to one embodiment includes a base 100, a sliding drive member 200, a buffer connection assembly 300, and a marking member 400. The sliding drive member 200 is mounted on the base 100. The buffer connection assembly 300 includes a first connection member 310, a second connection member 320, and an elastic member 330. The first connection member 310 is connected to the power output end of the sliding drive member 200, and the first connection member 310 is slidably connected to the second connection member 320. The ends of the elastic member 330 abut against the first connection member 310 and the second connection member 320, respectively. The marking member 400 is connected to the second connection member 320 and is used to mark the camera module.

[0034] In this embodiment, the marking mechanism 10 includes a base 100, a sliding drive 200, a buffer connection assembly 300, and a marking member 400. The base 100 serves as the support structure for the marking mechanism 10 and ensures that the marking mechanism 10 can perform marking operations stably. The sliding drive 200 is mounted on the base 100 and is used to output power to drive the marking member 400 to move, thereby completing the marking process. The marking member 400 is used to mark the camera module. Upon contact with the camera module, the marking portion of the marking member 400 leaves ink on the surface of the camera module, resulting in a mark on the camera module surface. The buffer connection assembly 300 is respectively connected to the sliding drive member 200 and the marking member 400. The buffer connection assembly 300 is used to transmit power and buffer the contact stress between the marking member 400 and the camera module. The buffer connection assembly 300 includes a first connection member 310 and a second connection member 320 that are slidably connected to each other. The first connection member 310 is connected to the power output end of the sliding drive member 200, and the second connection member 320 is connected to the marking member 400. An elastic member 330 is abutted between the first connection member 310 and the second connection member 320. The first connection member 310 and the second connection member 320 are moved away from each other under the elastic force of the elastic member 330.

[0035] When the marking mechanism 10 marks the camera module, the sliding drive member 200 will drive the buffer connection assembly 300 to move, and the buffer connection assembly 300 will drive the marking member 400 to move in the direction close to the camera module. After the marking portion of the marking member 400 contacts the camera module, the sliding drive member 200 will continue to drive the first connection member 310 to move a shorter distance at one end. Since the marking member 400 and the second connection member cannot continue to move after contacting the camera module, the first connection member and the second connection member will overcome the elastic force of the elastic member 330 and move against each other. As the two components slide and approach, the compressed elastic member 330 applies pressure to the second elastic member 330, causing the marking portion of the marking member 400 to abut against the camera module, thereby enabling the marking member 400 to leave a clear mark on the camera module. At the same time, after the marking member 400 contacts the camera module, the excessive contact stress generated between the marking member 400 and the camera module can be buffered by the elastic member 330. Compared with the traditional marking mechanism 10, the contact pressure between the marking member 400 and the camera module can be better controlled to prevent the marking member 400 from crushing the camera module.

[0036] like Figure 2As shown, in one embodiment, the base 100 includes a base body 110 and a mounting frame 120, the mounting frame 120 is connected to the base body 110, the sliding drive member 200 is installed on the mounting frame 120, and the second connecting member 320 is slidably connected to the mounting frame 120. In this embodiment, the second connecting member 320 is slidably connected to the mounting frame 120. During the marking process, the second connecting member 320 moves under the drive of the sliding drive member 200, and the second connecting member 320 also slides relative to the mounting frame 120. The relative sliding with the mounting frame 120 can make the second connecting member 320 more stable during the movement process, thereby making the state of the marking member 400 in contact with the camera module more stable, which helps to prevent the marking member 400 from damaging the camera module during marking.

[0037] like Figure 2 As shown, in one embodiment, the buffer connection assembly 300 further includes a guide rail 340 and a slider 350. The slider 350 is connected to the second connection member 320, and the guide rail 340 is connected to the mounting bracket 120. The slider 350 is provided with a slide groove, and the guide rail 340 is slidably disposed in the slide groove so that the slider 350 is slidably connected to the guide rail 340. In this embodiment, the second connection member 320 is connected to the slider 350, and the guide rail 340 is connected to the mounting bracket 120. The slider 350 slides with the guide rail 340 through the slide groove provided thereon, so that the second connection member 320 is slidably connected to the mounting bracket 120, thereby achieving the effect of improving the movement smoothness of the marking component 400.

[0038] like Figure 3 As shown, in one embodiment, the mounting frame 120 includes a frame body 121 and a threaded fastener 122. The frame body 121 is provided with a waist-shaped hole 121a, and the base body 110 is provided with a threaded hole. The threaded fastener 122 is sequentially passed through the waist-shaped hole 121a and the threaded hole, so that the threaded fastener 122 is threadedly connected to the base body 110. In this embodiment, the threaded fastener 122 is sequentially passed through the waist-shaped hole 121a of the frame body 121 and the threaded hole of the base body 110, and is screwed with the threaded holes, so that the frame body 121 and the base body 110 are fixed to each other. Since the hole body provided in the frame body 121 is a waist-shaped hole 121a, when the marking position needs to be adjusted, the threaded fastener 122 can be loosened and the frame body 121 can be moved along the extension direction of the waist-shaped hole 121a to change the position of the marking part 400, thereby achieving the effect of changing the marking position.

[0039] like Figure 1As shown, in one embodiment, the second connecting member 320 is provided with a sliding groove 321, and the first connecting member 310 is slidably disposed in the sliding groove 321 to achieve sliding connection between the first connecting member 310 and the second connecting member 320, and the two ends of the elastic member 330 are respectively in contact with the groove wall of the sliding groove 321 and the first connecting member 310. In this embodiment, the first connecting member 310 is slidably disposed in the sliding groove 321 provided by the second connecting member 320 to achieve sliding connection between the second connecting member 320 and the first connecting member 310, and the elastic member 330 is disposed in the sliding groove 321, and the two ends of the elastic member 330 are respectively in contact with the groove wall of the sliding groove 321 and the first connecting member 310 to apply elastic force to the first connecting member 310 and the second connecting member 320, respectively, to achieve the effect of moving the first connecting member 310 and the second connecting member 320 away from each other.

[0040] like Figure 1 As shown, in one embodiment, the elastic member 330 is a coil spring or an elastic rubber member. In this embodiment, the elastic member 330 is a coil spring, the two ends of which are respectively in contact with the first connecting member 310 and the second connecting member 320, and the coil spring is always in a compressed state to achieve the effect of driving the first connecting member 310 and the second connecting member 320 away from each other.

[0041] like Figure 1 and Figure 3 As shown, in one embodiment, the buffer connection assembly 300 includes a clamping member 380 and a fixing member 390. The clamping member 380 includes a first clamping portion 381 and a second clamping portion 382. The first clamping portion 381 is connected to the second connection member 310. The fixing member 390 is connected to the first clamping portion 381 and the second clamping portion 382, respectively. A clamping area is formed between the first clamping portion 381 and the second clamping portion 382. The fixing member 390 is used to adjust the size of the clamping area. The marking member 400 is interference-fitted in the clamping area. In this embodiment, a clamping area is formed between the first clamping portion 381 and the second clamping portion 382. The marking member 400 is interference-fitted in the clamping area, that is, the marking member 400 is connected to the clamping area by an interference fit. In this way, the friction between the marking member 400 and the first clamping portion 381 and the second clamping portion 382, respectively, ensures that the marking member 400 is stably positioned in the clamping area. The fixing part 390 is used to adjust the size of the clamping area. When it is necessary to change the contact stress between the marking part 400 and the camera module, the clamping area can be enlarged through the fixing part 390 so that the marking part 400 can move in the clamping area to change the relative position of the marking part 400 and the second connecting part 320. In this way, the initial distance between the marking part 400 and the camera module during the marking process can be adjusted, thereby changing the contact stress between the marking part 400 and the camera module.

[0042] like Figure 1 and Figure 3 As shown, in one embodiment, one end of the first clamping portion 381 is connected to one end of the second clamping portion 382, the other end of the first clamping portion 381 is provided with a threaded mounting hole, and the other end of the second clamping portion 382 is provided with a through hole, and the fixing member 390 includes a bolt, which is sequentially inserted into the through hole and the threaded mounting hole; the first clamping portion 381 and the second clamping portion 382 are an integrally formed structure. In this embodiment, one end of the first clamping portion 381 is integrally connected to one end of the second clamping portion 382, and the other end of the first clamping portion 381 and the other end of the second clamping portion 382 are connected by a bolt. By rotating the bolt, the end of the first clamping portion 381 with the threaded mounting hole and the end of the second clamping portion 382 with the through hole can be moved closer to or further away from each other, thereby achieving the effect of adjusting the size of the clamping area.

[0043] like Figure 1 and Figure 3 As shown, in one embodiment, a first anti-slip buffer layer is provided on a side of the first clamping portion 381 adjacent to the marking part 400, and a second anti-slip buffer layer is provided on a side of the second clamping portion 382 adjacent to the marking part 400, and the first anti-slip buffer layer and the second anti-slip buffer layer are respectively abutted against both sides of the marking part 400. In this embodiment, the first clamping part 381 is provided with a first anti-slip buffer layer, and the second clamping part 382 is provided with a second anti-slip buffer layer. The first anti-slip buffer layer and the second anti-slip buffer layer are both frosted silicone gasket structures. The first anti-slip buffer layer and the second anti-slip buffer layer are respectively abutted against the two sides of the marking part 400, which can increase the friction between the marking part 400 and the first clamping part 381 and the second clamping part 382, thereby avoiding relative sliding of the marking part 400 with the second connecting part during the marking process, thereby improving the stability of the marking part 400. At the same time, the silicone material has good buffering properties, which can buffer the pressure applied to the marking part 400 by the first clamping part 381 and the second clamping part 382, and prevent the marking part 400 from being crushed.

[0044] It can be understood that the marking work is completed by contacting the marking part of the marking member 400 with the camera module so that the ink of the marking part adheres to the surface of the camera module. However, when marking the camera module by the above-mentioned point pressure marking method, due to the weak contact strength between the marking part of the marking member 400 and the camera module, when the ink color is lighter or the concentration of the ink stored in the marking member 400 is lower, it will not be possible to leave a clear mark on the camera module. Figure 4As shown, in one embodiment, the buffer connection assembly 300 further includes a rotating member 360, which is rotatably connected to the second connection member 320 and connected to the clamping member 380. The marking mechanism 10 further includes a rotary drive member 600, whose power output end is connected to the rotating member 360, and the rotary drive member 600 is used to drive the rotating member 360 to rotate. In this embodiment, the second connection member 320, the rotating member 360, the clamping member 380, and the marking member 400 are connected in sequence, and the rotating member 360 is rotatably connected to the second connection member 320. The marking member 400 can achieve rotation through the indirect connection with the rotating member 360. The marking mechanism 10 further includes a rotary drive member 600, which can drive the rotating member 360 to rotate, thereby driving the marking member 400 to rotate. When the sliding drive member 200 drives the marking member 400 to move downward until the marking part of the marking member 400 abuts against the camera module, the rotating drive member 600 will drive the rotating member 360 to rotate, thereby driving the marking member 400 to rotate. In this way, the contact position between the marking part of the marking member 400 and the camera module will be continuously refreshed, and the ink on the marking part will continue to adhere to the camera module, thereby leaving a clear mark on the surface of the camera module.

[0045] It can be understood that the relative position of the marking member 400 and the clamping member 380 can be changed by the cooperation of the fixing member 390 and the clamping member 380. At the same time, the marking member 400 needs to rotate around its own axis during the marking process. In order to achieve the above-mentioned movement effect of the marking member 400 and avoid movement interference. Figure 4 and Figure 6 As shown, in one embodiment, the rotating member 360 includes a rotating sleeve 361, the second connecting member 320 is provided with a rotating connecting hole 325, the rotating sleeve 361 is passed through the rotating connecting hole 325, the power output end of the rotating driving member 600 is connected to the rotating sleeve 361, the rotating sleeve 361 is connected to the clamping member 380, and the marking member 400 is passed through the rotating sleeve 361. In this embodiment, the rotating sleeve 361 rotates and passes through the rotating connecting hole 325 on the second connecting member 320, so that the rotating sleeve 361 can rotate on the second connecting member 320; since the end of the rotating sleeve 361 is connected to the clamping member 380, and the marking member 400 is passed through the rotating sleeve 361, the central axis of the marking member 400 coincides with the central axis of the rotating sleeve 361. In this way, when the rotating driving member 600 drives the rotating sleeve 361 to rotate, it can drive the marking member 400 to rotate around its own central axis. In addition, when adjusting the relative position of the marking member 400 and the clamping member 380, the marking member 400 will always be passed through the rotating sleeve 361, which can avoid movement interference between the marking member 400 and the rotating sleeve 361.

[0046] In order to improve the rotation stability of the rotating sleeve 361. Figure 6 As shown, in one embodiment, the buffer connection assembly 300 further includes a bearing member, which is disposed in the rotation connection hole 325, and the rotating sleeve 361 is passed through the bearing member. In this embodiment, by installing the bearing member in the rotation connection hole 325 and rotating the rotating sleeve 361 to pass through the through hole of the bearing member, when the rotating sleeve 361 rotates, the bearing member can convert the sliding friction originally experienced by the rotating sleeve 361 into rolling friction, effectively reducing the resistance experienced by the rotating sleeve 361 during rotation, making the rotating sleeve 361 rotate more smoothly. In this way, when the marking member 400 rotates to apply ink on the camera module, the rotation of the marking portion of the marking member 400 will be more stable, making the ink adhesion effect clearer and more uniform.

[0047] It is understandable that in order to achieve the effect of adjusting the size of the clamping area, the rotating sleeve 361 cannot be connected to the first clamping part 381 and the second clamping part 382 at the same time, otherwise the first clamping part 381 and the second clamping part 382 will not be able to move relative to each other, and thus the initial position of the marking member 400 and the camera module cannot be changed. However, when the rotating sleeve 361 is only connected to the first clamping part 381 or the second clamping part 382, the rotating member 360 will vibrate due to the uneven dynamic load, thereby causing the marking part of the marking member 400 to shift position during the marking process. Figure 4 As shown, in one embodiment, the buffer connection assembly 300 also includes a rotating transmission member 370, and the rotating transmission member 370 includes a rigid connection part 371 and a flexible connection part 372, and the rigid connection part 371 and the flexible connection part 372 are both connected to the rotating sleeve 361, and the rigid connection part 371 and the flexible connection part 372 are respectively connected to the first clamping part 381 and the second clamping part 382. In this embodiment, the rotating sleeve 361 and the clamping member 380 are connected through the rotating transmission member 370. The rotating transmission member 370 includes a rigid connection part 371 and a flexible connection part 372. The flexible connection part 372 is made of rubber or plastic with good deformation ability, so that the flexible connection part 372 has good deformation ability. The rotating sleeve 361 is connected to the first clamping part 381 and the second clamping part 382 through the rigid connection part 371 and the flexible connection part 372 respectively, so that the rotating member 360 can better maintain its own dynamic load balance during the rotation process. At the same time, since the flexible connection part 372 has good deformation ability, it can be deformed with the relative movement of the first clamping part 381 and the second clamping part 382, thereby achieving the effect of changing the initial position of the marking part 400 and the camera module.

[0048] It is understandable that the rotating member 360 needs to move up and down together with the second connecting member 320, and also needs to rotate on the second connecting member 320. In order to drive the rotating member 360, the traditional rotary drive member 600 is usually installed on the second connecting member 320 to achieve the effect of driving the rotating member 360 to rotate. However, the rotary drive member 600 has a large weight and a relatively bloated structure. When the rotary drive member 600 is installed on the second connecting member 320, it will bring a large load to the sliding drive member 200, causing the stability of the lifting movement of the second connecting member 320 to decrease, and ultimately causing the marking position of the marking member 400 to shift. Figure 4 As shown, in one embodiment, the rotating drive member 600 includes a driving motor 610 and a telescopic linkage member 620, the driving motor 610 is installed on the mounting frame 120, the power output unit of the driving motor 610 is connected to the telescopic linkage member 620, and the telescopic linkage member 620 is connected to the rotating sleeve 361. In this embodiment, the driving motor 610 of the rotating driving member 600 is installed on the mounting frame 120, and the telescopic linkage member 620 is respectively connected to the rotating member 360 and the output end of the driving motor 610. When the second connecting member 320 drives the rotating member 360 to perform lifting and lowering movements, the telescopic linkage member 620 can be extended and retracted along with the movement of the rotating member 360. When the marking member 400 contacts the camera module, the driving motor 610 can drive the rotating member 360 to rotate through the stretched telescopic linkage member 620, that is, the power output end of the rotating driving member 600 can always be connected to the rotating member 360. In this way, the rotating member 360 can be driven without installing the rotating driving member 600 on the second connecting member 320, which can reduce the load of the sliding driving member 200, making the lifting and lowering movement of the marking member 400 smoother, thereby preventing the marking member 400 from offsetting.

[0049] In order to improve the rotation stability of the marking member 400, to make the structure of the rotary drive member 600 more compact and lightweight, and to extend the service life of the rotary drive member 600. Figure 5As shown, in one embodiment, the rotating drive member 600 also includes a first transmission shaft 630 and a second transmission shaft 640, and the power output end of the drive motor 610, the first transmission shaft 630, the telescopic linkage member 620, the second transmission shaft 640 and the rotating member 360 are connected in sequence. In this embodiment, the rotational power of the drive motor 610 will be transmitted to the rotating sleeve 361 through the first transmission shaft 630, the telescopic linkage 620 and the second transmission shaft 640 in sequence, so that the marking part 400 rotates. Since the first transmission shaft 630 and the second transmission shaft 640 are shaft structures, they have the characteristic of a small dynamic load coefficient. Transmission through the first transmission shaft 630 and the second transmission shaft 640 can reduce the vibration level of the marking part 400 during rotation, thereby preventing the marking part 400 from shifting; at the same time, the first transmission shaft 630 and the second transmission shaft 640 are lighter than the telescopic linkage 620, so that the structure of the rotating drive part 600 can be more compact, occupy less space, and can reduce the load of the drive motor 610, thereby extending the service life of the drive motor 610.

[0050] In order to improve the rotation stability of the marking member 400 and prevent the marking member 400 from deflecting during the rotation process. Figure 5 and Figure 6 As shown, in one embodiment, the rotating drive member 600 also includes a connecting sleeve 650, which is respectively connected to the second transmission shaft 640 and the rotating sleeve 361, and the connecting sleeve 650 is sleeved on the marking member 400, and the shape of the marking member 400 is adapted to the shape of the inner wall of the connecting sleeve 650. In this embodiment, the rotating drive member 600 also includes a connecting sleeve 650, and the second transmission shaft 640 is connected to the rotating sleeve 361 of the rotating member 360 through the connecting sleeve 650, so as to drive the rotating sleeve 361 to rotate; at the same time, since the connecting sleeve 650 is sleeved on the marking member 400, and the shape of the marking member 400 is adapted to the shape of the inner wall of the connecting sleeve 650, the end of the marking member 400 is fixed to the connecting sleeve 650, and the marking member 400 is also clamped by the clamping member 380. In this way, the marking member 400 can always rotate around its central axis, which can effectively improve the rotation stability of the marking member 400, thereby preventing the marking member 400 from offsetting during the marking process.

[0051] like Figure 5 and Figure 6As shown, in one embodiment, the telescopic linkage 620 includes a transmission column 622, a transmission cylinder 621 and a plurality of strip-shaped protrusions 623, the transmission cylinder 621 is connected to the first transmission shaft 630, the transmission column 622 is connected to the second transmission shaft 640, the plurality of strip-shaped protrusions 623 are all connected to the transmission column 622, and the length direction of the plurality of strip-shaped protrusions 623 is parallel to the length direction of the transmission column 622, the inner wall of the transmission cylinder 621 is provided with a plurality of strip-shaped grooves 621a, the transmission cylinder 621 is sleeved on the transmission column 622, and the plurality of strip-shaped protrusions 623 are slidably arranged in the plurality of strip-shaped grooves 621a in a one-to-one correspondence. In this embodiment, the transmission cylinder 621 is sleeved on the transmission column 622, so that the transmission column 622 and the transmission cylinder 621 can be telescopically slidable. At the same time, the multiple strip-shaped protrusions 623 connected to the transmission column 622 are respectively slidably set in the multiple strip-shaped grooves 621a opened on the inner wall of the transmission cylinder 621. After the transmission column 622 and the transmission cylinder 621 are telescopically slid, the multiple strip-shaped protrusions 623 can still cooperate with the multiple strip-shaped grooves 621a. When the traditional cylinder rotates, the multiple strip-shaped protrusions 623 can be used to transmit the power to drive the transmission column 622 and the transmission cylinder 621 to rotate together, so that the power output end of the rotating drive member 600 can always be connected to the rotating member 360. In addition, the transmission cylinder 621 and the transmission column 622 are transmitted through the multiple strip-shaped protrusions 623. The multiple strip-shaped protrusions 623 can play a role in distributing stress, so that the transmission torque limit between the transmission column 622 and the traditional cylinder is higher, thereby making the telescopic linkage 620 more reliable and having a longer service life.

[0052] In order to improve the smoothness of the telescopic linkage 620 during the telescopic process. Figure 7As shown, in one embodiment, the telescopic linkage 620 also includes a plurality of rolling members 624, and the plurality of rolling members 624 are connected one-to-one with the plurality of strip protrusions 623, and each of the rolling members 624 includes a plurality of rollers 624a, and the plurality of rollers 624a of each rolling member 624 are sequentially connected to the strip protrusion 623 along the length direction of the strip slide 621a, and the plurality of rollers 624a of each rolling member 624 are all in contact with the groove wall of the corresponding strip slide 621a. In this embodiment, the multiple rollers 624a on each strip-shaped protrusion 623 will replace the strip-shaped protrusion 623 and abut against the groove wall of the strip-shaped slide groove 621a. During the extension and retraction of the telescopic linkage 620, the rollers 624a can convert the sliding friction force exerted on the strip-shaped protrusion 623 into rolling friction force, thereby reducing the resistance exerted on the telescopic linkage 620 during the extension and retraction process. In this way, the smoothness of the telescopic linkage 620 during the extension and retraction process can be effectively improved, and the situation of jamming or failure of the telescopic linkage 620 during movement can be avoided, so that the marking part 400 can be more stable during the lifting process, thereby preventing the marking part 400 from offsetting during the lifting process.

[0053] The present application also provides a focusing device, which includes the marking mechanism 10 described in any of the above embodiments. Figure 1 As shown, in one embodiment, the marking mechanism 10 includes a base 100, a sliding drive member 200, a buffer connection assembly 300, and a marking member 400. The sliding drive member 200 is mounted on the base 100. The buffer connection assembly 300 includes a first connection member 310, a second connection member 320, and an elastic member 330. The first connection member 310 is connected to the power output end of the sliding drive member 200, and the first connection member 310 is slidably connected to the second connection member 320. The two ends of the elastic member 330 are respectively in contact with the first connection member 310 and the second connection member 320. The marking member 400 is connected to the second connection member 320 and is used to mark the camera module.

[0054] In this embodiment, the marking mechanism 10 includes a base 100, a sliding drive 200, a buffer connection assembly 300, and a marking member 400. The base 100 serves as the support structure for the marking mechanism 10 and ensures that the marking mechanism 10 can perform marking operations stably. The sliding drive 200 is mounted on the base 100 and is used to output power to drive the marking member 400 to move, thereby completing the marking process. The marking member 400 is used to mark the camera module. Upon contact with the camera module, the marking portion of the marking member 400 leaves ink on the surface of the camera module, resulting in a mark on the camera module surface. The buffer connection assembly 300 is respectively connected to the sliding drive member 200 and the marking member 400. The buffer connection assembly 300 is used to transmit power and buffer the contact stress between the marking member 400 and the camera module. The buffer connection assembly 300 includes a first connection member 310 and a second connection member 320 that are slidably connected to each other. The first connection member 310 is connected to the power output end of the sliding drive member 200, and the second connection member 320 is connected to the marking member 400. An elastic member 330 is abutted between the first connection member 310 and the second connection member 320. The first connection member 310 and the second connection member 320 are moved away from each other under the elastic force of the elastic member 330.

[0055] When the marking mechanism 10 marks the camera module, the sliding drive member 200 will drive the buffer connection assembly 300 to move, and the buffer connection assembly 300 will drive the marking member 400 to move in the direction close to the camera module. After the marking portion of the marking member 400 contacts the camera module, the sliding drive member 200 will continue to drive the first connection member 310 to move a shorter distance at one end. Since the marking member 400 and the second connection member cannot continue to move after contacting the camera module, the first connection member and the second connection member will overcome the elastic force of the elastic member 330 and move against each other. As the two components slide and approach, the compressed elastic member 330 applies pressure to the second elastic member 330, causing the marking portion of the marking member 400 to abut against the camera module, thereby enabling the marking member 400 to leave a clear mark on the camera module. At the same time, after the marking member 400 contacts the camera module, the excessive contact stress generated between the marking member 400 and the camera module can be buffered by the elastic member 330. Compared with the traditional marking mechanism 10, the contact pressure between the marking member 400 and the camera module can be better controlled to prevent the marking member 400 from crushing the camera module.
