[0046] Some embodiments of the utility model will be described in detail below in combination with the drawings. In the case of no conflict, the following examples and the features in the examples can be combined with each other.

[0047] In order to improve the problem that the application range of the test tool of the related camera module is limited and the cost is high, referring to Figure 1 And Figure 2 The utility model provides a camera centering device 100, including chip board clamping module 2, shell clamping module 3, bearing base 4, centering platform 5, position adjustment module 6 and base plate 1.

[0048] Bearing base 4 and shell clamping module 3 are fixedly arranged on base plate 1 by welding, screw connection and the like, and chip board clamping module 2 is arranged on position adjustment module 6 in a detachable or undetachable manner by welding, screw connection and the like, and position adjustment module 6 and centering platform 5 are slidably arranged on base plate 1.

[0049] Chip board clamping module 2 forms a chip board clamping area with adjustable size, and shell clamping module 3 forms a shell clamping area with adjustable size.

[0050] The position adjusting module 6 is used for adjusting the position of the chip board clamping module 2.

[0051] The bearing base 4 is used for bearing the lens shell of the camera and the chip board.

[0052] The substrate 1 can be a regular geometric structure or an irregular geometric structure.

[0053] The relative position of the centering platform 5 and the bearing base 4 can be flexibly set, for example, referring to the figure, the centering platform 5 is below the bearing base 4. Alternatively, the centering platform 5 can be above the bearing base 4, or the centering platform 5 can be on the left side or the right side of the bearing base 4. The relative position of the two is not limited.

[0054] Through the above structure, the shell clamping module 3 can clamp camera shells of different sizes through the shell clamping area and place them on the bearing base 4, and the chip board clamping module 2 can clamp chip boards of different sizes through the chip board clamping area and place the chip boards on the bearing base 4, and make the chip boards fall into the chip mounting area in the lens shell, that is, the camera shell and the chip board are in an assembled state. Further, by adjusting the position of the chip board clamping module 2 clamping the chip board and the centering platform 5, the optical center and the image center can be adjusted to coincide.

[0055] During the test process, the camera centering device 100 provided by the utility model is used to place the lens shell on the bearing base 4, and the chip board falls into the chip mounting area in the lens shell. The chip board is connected with the display device, the display device displays the image shot by the chip board, and the optical center and the image center can be obtained in the displayed image, so that whether the optical center and the image center coincide can be known. In the case of not coinciding, the position of the chip board clamping module 2 clamping the chip board and the centering platform 5 is adjusted until the optical center and the image center coincide in the image displayed on the display screen.

[0056] In this way, the camera centering device 100 provided by the utility model can satisfy cameras of different lengths and with left-right offset of the chip center, realize the centering test of cameras of different specifications, greatly improve the universality of the camera centering device 100, and further reduce the cost.

[0057] The structure of the position adjusting module 6 can be flexibly set, for example, it can be a single-direction moving mechanism composed of a carrier plate and a single driving element (such as a pneumatic cylinder or an electric cylinder), or a double-direction moving mechanism composed of a carrier plate and two driving elements (such as pneumatic cylinders or electric cylinders). The above-mentioned manners are all examples, and the implementation manner is not limited.

[0058] In order to improve the flexibility of position adjustment, the concept of bidirectional (i.e. front-back and left-right, which can also be understood as x-direction and y-direction) is introduced in the position adjustment module 6. For example, referring to Figure 2 The position adjustment module 6 includes a base 61, a first sliding table 62, a second sliding table 63, a first driving member 64 and a second driving member 65. The base 61 is arranged on the base plate 1, the first sliding table 62 is slidingly arranged on the base 61, the second sliding table 63 is slidingly arranged on the first sliding table 62, and the moving directions of the first sliding table 62 and the second sliding table 63 are perpendicular to each other. The first driving member 64 is used to drive the first sliding table 62 to move along the width direction of the base 61, and the second driving member 65 is used to drive the second sliding table 63 to move along the length direction of the base 61. The chip board clamping module 2 is fixed on the second sliding table 63.

[0059] The base 61 can not only support the first sliding table 62 and the second sliding table 63, but also can lift the first sliding table 62 and the second sliding table 63, so that the chip board clamping module 2 is located above the bearing base 4.

[0060] The first driving member 64 and the second driving member 65 can be a pneumatic cylinder, an electric cylinder or any automatic driving mechanism, and the first driving member 64 and the second driving member 65 can also be a driving mechanism composed of a rotating rod and a nut matched by threads, and the implementation manner is not limited.

[0061] Through the above structure, the position adjustment module 6 can move in two directions, such as front-back movement and left-right movement, which greatly improves the flexibility of position adjustment, so as to ensure that the chip board clamped by the chip board clamping module 2 through the position adjustment module 6 is moved to a suitable position, so as to achieve the coincidence of the optical center and the image center.

[0062] Similarly, the structure of the centering platform 5 can be flexibly arranged, for example, it can be composed of a single-direction moving mechanism and a centering device 51, or it can be composed of a centering device 51 and a bidirectional moving mechanism. The above-mentioned manners are all examples, and the implementation manner is not limited.

[0063] For example, referring to Figure 4 The centering platform 5 includes a centering device 51, a third sliding table 52, a fourth sliding table 53, a fourth driving member 54 and a third driving member 55. The third sliding table 52 is slidingly arranged on the base plate 1, the fourth sliding table 53 is slidingly arranged on the third sliding table 52, the centering device 51 is arranged on the fourth sliding table 53, and the moving directions of the third sliding table 52 and the fourth sliding table 53 are perpendicular to each other. The third driving member 55 is used to drive the third sliding table 52 to move along the width direction of the base plate 1, and the fourth driving member 54 is used to drive the fourth sliding table 53 to move along the length direction of the base plate 1.

[0064] The center position of the centering device 51 is provided with a reference figure, which is used as a reference for the camera centering. For example, if the reference figure of the image collected by the chip board coincides with the optical center, the optical center and the image center coincide, otherwise the optical center and the image center do not coincide, and the position of the chip board or the centering device 51 needs to be adjusted.

[0065] The third driving member 55 and the fourth driving member 54 can be a gas cylinder, an electric cylinder or any automatic driving mechanism, and the third driving member 55 and the fourth driving member 54 can also be a driving mechanism composed of a rotating rod and a nut matched by threads, and the implementation manner is not limited.

[0066] Through the above structure, the centering device 51 can move in two directions, such as forward and backward movement and left and right movement, which greatly improves the flexibility of position adjustment, so as to ensure that the centering device 51 moves to the appropriate position to achieve the coincidence of the optical center and the image center.

[0067] In the camera centering device 100, the structure of the bearing base 4 can be flexibly set, for example, it can be composed of a plate, or it can be composed of a plate and a column supporting the plate, and the above-mentioned manners are examples, and the implementation manner is not limited.

[0068] In order to cooperate with the centering platform 5 to facilitate the implementation of camera centering test, referring to Figure 3 and Figure 4 , the bearing base 4 includes a bearing plate 41 and a bearing column 42, the bearing plate 41 is provided with a test hole 43, the bearing column 42 is arranged on the base plate 1, the bearing plate 41 is arranged on the bearing column 42, and the bearing plate 41 is located above the centering platform 5.

[0069] The test hole 43 can also be understood as a shooting hole, which is used for the lens shell and the chip board placed on the bearing base 4 to shoot the centering platform 5 through the test hole 43 to obtain an image.

[0070] The bearing plate 41 can be a regular geometric structure, such as a rectangle, a circle, etc., or an irregular geometric structure. The number of bearing columns 42 can be flexibly set, for example, the bearing column 42 can be one or more, and the number is not limited.

[0071] However, by way of example, referring to Figure 4 , the bearing column 42 is two, the two bearing columns 42 are located on the same side of the centering platform 5, and the bearing plate 41 is fixed to the end of the bearing column 42 away from the base plate 1. In this way, the bearing plate 41 can be stably supported and located above the centering platform 5.

[0072] To ensure that the chip board can acquire a clear image during testing, with the lens housing and chip board in conjunction, refer to... Figure 5 A supplementary light 7 is provided on the surface of the support plate 41 facing the central platform 5.

[0073] The number of supplementary lights 7 can be flexibly set. For example, there can be multiple supplementary lights 7 arranged at equal intervals around the test hole 43, or there can be two rows of supplementary lights 7 arranged on both sides of the test hole 43. The number and setting position of these supplementary lights are not limited.

[0074] The supplementary light 7 can supplement the light when it is insufficient, so as to ensure that the camera housing and chip board on the support base 4 can obtain clear images.

[0075] To ensure the camera housing fits securely onto the support base 4, refer to... Figure 6 and Figure 7 A detachable limiting protrusion 44 is provided on the surface of the support plate 41 facing away from the central platform 5. The limiting protrusion 44 is adapted to the lens housing, and the test hole 43 of the support plate 41 is located at the center of the limiting protrusion 44.

[0076] The fitting of the limiting protrusion 44 with the lens housing means that the lens housing is fitted onto the limiting protrusion 44, that is, the lens housing and the limiting protrusion 44 are engaged. Moreover, the limiting protrusion 44 can be set on the support plate 41 by screws, pins, clips, magnets or any of the detachable structures.

[0077] With the above structure, for different models and specifications of cameras, the limiting protrusion 44 of the carrier plate 41 can be replaced so that the limiting protrusion 44 is always adapted to the lens housing of the camera, so as to ensure that the lens housing is stably and securely covered on the carrier plate 41.

[0078] The chip board will eventually be located on the chip mounting area of ​​the lens housing, which is covered by the carrier plate 41. To prevent the chip board from jumping out of the chip mounting area of ​​the lens housing due to external forces such as vibration or strong winds, a chip board limiting mechanism is provided on the carrier plate 41. (Refer to...) Figure 4 and Figure 6 The support base 4 also includes a connecting rod 45 and a cover plate 46. The cover plate 46 is hinged to the support plate 41 via the connecting rod 45, and the connecting rod 45 is close to the limiting protrusion 44.

[0079] The cover plate 46 can be either a regular geometric structure or an irregular geometric structure, and its shape and structure are not restricted.

[0080] Through the above structure, the cover plate 46 can rotate on the bearing plate 41, so that by rotating the cover plate 46, the cover plate 46 can be covered on the limiting protrusion 44. In the case that the lens shell of the camera is located on the bearing plate 41 and the chip plate of the camera is located on the mounting area of the lens shell, the cover plate 46 is used to cover above the chip plate to limit the chip plate and avoid displacement of the chip plate.

[0081] In other cases, the limiting protrusion 44 can be exposed by rotating the cover plate 46, so that the shell clamping module 3 clamps the lens shell and the chip clamping module clamps the chip plate.

[0082] In order to avoid the cover plate 46 from being opened or opened halfway due to external force, the cover plate 46 and the bearing plate 41 can be provided with matching threaded holes, and then in the case that the cover plate 46 covers the chip plate to limit, the cover plate 46 is locked and fixed on the bearing plate 41 by using screws.

[0083] In order to facilitate the test of the camera, the bearing plate 41 is provided with a sensor on the side away from the center platform 5, and the sensor is used to detect whether the cover plate 46 is closed (i.e. covered above the limiting protrusion 44).

[0084] For example, the inductive head is arranged in the right groove of the bearing plate 41, and the sensor can be a photoelectric detector or a pressure sensor, so that in the case that the cover plate 46 is closed and no light or pressure is detected, an opening signal is output, otherwise a closing signal is output. The sensor can also be any other detector, which is not limited here.

[0085] The sensor can be connected with the test controller of the camera, so that in the case that the cover plate 46 is closed in place, an opening signal is output to the test controller to start the test of the camera, and in the case that the cover plate 46 is opened, a closing signal is output to the test controller to stop the test.

[0086] Through the above arrangement, the start and stop of the camera test can be automatically controlled, so as to save manpower and reduce test cost.

[0087] In the camera centering device 100 provided by the utility model, in order to make the chip plate clamping module 2 can clamp chip plates of different sizes, so as to adapt to camera modules of different models, referring to Figure 8 , the chip plate clamping module 2 comprises a first pneumatic assembly 21, a first clamping jaw 22 and a second clamping jaw 23.

[0088] The first pneumatic assembly 21 is arranged on the adjusting module, the first clamping jaw 22 and the second clamping jaw 23 are connected with the first pneumatic assembly 21, and the first clamping jaw 22 and the second clamping jaw 23 are arranged opposite to each other.

[0089] The chip board clamping area is formed between the first clamping jaw 22 and the second clamping jaw 23.

[0090] The first pneumatic assembly 21 drives the first clamping jaw 22 and the second clamping jaw 23 to move closer to or farther away from each other.

[0091] The first pneumatic assembly 21 can be a cylinder, and the cylinder includes two output shafts, and the first clamping jaw 22 and the second clamping jaw 23 are arranged on the two output shafts, respectively. The two output shafts move closer to or farther away from each other under the action of the cylinder, so as to drive the first clamping jaw 22 and the second clamping jaw 23 to move closer to or farther away from each other. Thus, by adjusting the distance between the first clamping jaw 22 and the second clamping jaw 23, lens housings of different sizes can be clamped.

[0092] The first clamping jaw 22 and the second clamping jaw 23 have the same structure, and the structure of the first clamping jaw 22 and the second clamping jaw 23 can be flexibly set. For example, it can be a long rod 24.

[0093] Referring to Figure 3 , the first clamping jaw 22 and the second clamping jaw 23 each can include a long rod 24 and a grab rod 25. One end of the long rod 24 is connected to one output shaft of the first pneumatic assembly 21, and the grab rod 25 is arranged at the end of the long rod 24 away from the first pneumatic assembly. The grab rod 25 is perpendicular to the long rod 24. At this time, the chip board clamping area is formed between the two grab rods 25 of the first clamping jaw 22 and the second clamping jaw 23.

[0094] As described above, in order to enable the housing clamping module 3 to clamp lens housings of different sizes to adapt to camera modules of different models, referring to Figure 8 , the housing clamping module 3 includes a support seat 31, a second pneumatic assembly 32, a third clamping jaw 33, and a fourth clamping jaw 34.

[0095] The support seat 31 is arranged on the base plate 1, and the third clamping jaw 33 and the fourth clamping jaw 34 are connected to the second pneumatic assembly 32, and the third clamping jaw 33 and the fourth clamping jaw 34 are arranged opposite to each other.

[0096] The housing clamping area is formed between the third clamping jaw 33 and the fourth clamping jaw 34.

[0097] The second pneumatic assembly 32 drives the third clamping jaw 33 and the fourth clamping jaw 34 to move closer to or farther away from each other.

[0098] The second pneumatic assembly 32 can be a cylinder, and the cylinder includes two output shafts, and the third clamping jaw 33 and the fourth clamping jaw 34 are arranged on the two output shafts, respectively. The two output shafts move closer to or farther away from each other under the action of the cylinder, so as to drive the third clamping jaw 33 and the fourth clamping jaw 34 to move closer to or farther away from each other. Thus, by adjusting the distance between the third clamping jaw 33 and the fourth clamping jaw 34, lens housings of different sizes can be clamped.

[0099] The third clamping jaw 33 and the fourth clamping jaw 34 are the same structure, and the structure of the third clamping jaw 33 and the fourth clamping jaw 34 can be flexibly set. For example, it can be a regular long rod 24, or it can be irregular in any shape, and the structure shape is not limited.

[0100] In order to facilitate control, with reference to Figure 1 and Figure 2 It can also include two control buttons 8 connected with the pneumatic controller, the electromagnetic valve and the starting controller. The electromagnetic valve can be two. The pneumatic controller is connected with the cylinder of the first pneumatic assembly 21 through one electromagnetic valve, and is connected with the cylinder of the second pneumatic assembly 32 through another electromagnetic valve.

[0101] The two control buttons 8 correspond to the cylinders of the first pneumatic assembly 21 and the second pneumatic assembly 32 respectively.

[0102] Therefore, the opening and closing of the first pneumatic assembly 21 and the second pneumatic assembly 32 can be controlled through the control button 8. The pneumatic controller controls the output force of the first pneumatic assembly 21 and the second pneumatic assembly 32 by sending control signals to the electromagnetic valve, so as to make the chip board clamping module 2 clamp or release the chip board, and make the shell clamping module 3 release or clamp the lens shell.

[0103] In addition, since the chip board clamped by the final chip board clamping module 2 is to be placed on the lens shell, and the lens shell is placed on the bearing plate 41 by the shell clamping module 3 through clamping, the target positions of the chip board clamping module 2 and the shell clamping module 3 are the same. At this time, the first clamping jaw 22 and the second clamping jaw 23 are easy to overlap and collide with the third clamping jaw 33 and the fourth clamping jaw 34.

[0104] In order to avoid collision between the first clamping jaw 22, the second clamping jaw 23 and the third clamping jaw 33 and the fourth clamping jaw 34, with reference to Figure 3 , the third clamping jaw 33 and the fourth clamping jaw 34 are provided with an avoidance slot 35.

[0105] The avoidance slot 35 on the third clamping jaw 33 is clamped with the first clamping jaw 22, and the avoidance slot 35 on the fourth clamping jaw 34 is clamped with the second clamping jaw 23.

[0106] Through the setting of the avoidance slot 35, in the process of placing the chip board on the lens shell on the bearing plate 41 by the chip board clamping module 2, the first clamping jaw 22 located above the third clamping jaw 33 falls into the avoidance slot 35, and the second clamping jaw 23 located above the fourth clamping jaw 34 falls into the avoidance slot 35, without collision, so as to protect the clamping module and the chip board. At the same time, the setting of the avoidance slot 35 reduces the distance between the chip board clamped by the chip board clamping module 2 and the lens shell on the bearing plate 41, so that the chip board can be placed slowly.

[0107] Exemplarily, based on the camera centering device 100 described above, the test process of the camera test is as follows: when the camera module needs to be tested, first, the lens shell and the chip of the camera module are placed on the limiting protrusion 44 by the action of the chip board clamping module 2 and the shell clamping module 3, and the cover plate 46 is closed; after the cover plate 46 is closed in place, the sensor outputs an opening signal to start the test; after entering the test, the display screen connected to the chip board displays the shooting image in real time, and the optical center and the image center are displayed on the image; by adjusting the positions of the centering platform 5 and the position adjusting module 6, the two centers are overlapped.

[0108] In the camera centering device 100, when different camera modules are replaced, the limiting protrusion is replaced to adapt to different types of camera modules, so that the camera centering device 100 can adapt to any camera, greatly improving the versatility. And in the test process, when the optical center and the image center are not overlapped, the positions of the position adjusting module 6 and the centering platform 5 are adjusted to make the two centers overlapped, further improving the versatility.

[0109] Based on the same concept as the camera centering device 100 described above, the utility model embodiment further provides a camera centering system, which comprises the camera centering device 100 provided above and the lens shell and chip board of the camera to be tested.

[0110] In summary, the camera centering device and system provided by the utility model embodiment have at least the following beneficial effects:

[0111] (1) The centering platform and the position adjusting module can be adjusted in the left-right direction and the front-back direction, so as to meet the camera with different lengths and chip center left-right offset, greatly improving the versatility;

[0112] (2) By replacing the limiting protrusion, different types of camera modules can be adapted, further improving the versatility.

[0113] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, but not to limit them; although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that: they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
