Description

Technical Field

[0001] This utility model relates to the technical field of fixtures, and in particular to a positioning plate and testing fixture for a camera module. Background Technology

[0002] In the automated production of mobile phone cameras, an ACF (Anisotropic Conductive Film) bonding process is required. The mobile phone camera module completes the ACF bonding process on the carrier board. Then, a transfer device is used to transfer the camera module to the positioning plate of the test fixture. The test fixture connects the ACF connector and energizes it, thereby enabling the camera module to be powered on for testing.

[0003] Conventionally, material handling equipment uses a suction head to pick up the camera module and place it into the positioning slot of the positioning plate. However, there is a certain height difference between the camera module of the suction head and the positioning slot. When the camera module falls into the positioning slot, the anisotropic conductive film is prone to shifting off the positioning slot, making the connector of the anisotropic conductive film easily damaged or deformed when plugged in. Utility Model Content

[0007] A positioning plate for a camera module according to an embodiment of the present utility model has at least the following beneficial effects:

[0008] This invention utilizes a positioning plate with a plate body. The top of the plate body defines a first receiving groove for accommodating the camera body and a second receiving groove for accommodating the anisotropic conductive film. The positioning plate also includes positioning pins and guide sections. When the suction head places the camera module above the positioning plate, the guide section is positioned at the top of the positioning pin, bringing it closer to the camera. The guide section tapers along the height of the positioning pin. When the camera module falls freely, the anisotropic conductive film moves along the guide section, allowing it to smoothly descend vertically along the positioning pin. The multiple positioning pins precisely limit the position of the anisotropic conductive film, preventing the connector of the film from shifting during the camera module's free fall. This ensures that the connector of the anisotropic conductive film will not be damaged when it mates with the socket of the test fixture during testing, improving test reliability and significantly reducing defective products.

[0009] According to a first aspect of the present invention, a positioning plate for a camera module is provided, wherein the guide portion is a conical structure.

[0010] According to a first aspect of the present invention, a positioning plate for a camera module is provided, wherein a positioning groove is provided in the second receiving groove, and the positioning pin and the positioning groove cooperate for positioning.

[0011] According to a first aspect of the present invention, a positioning plate for a camera module is provided, wherein a through hole is provided on the bottom wall of the positioning groove, a bolt is inserted in the through hole, and a threaded hole is provided on the positioning pin, wherein the bolt passes through the through hole and is tightened into the threaded hole.

[0012] According to a first aspect embodiment of the present invention, a positioning plate for a camera module is provided, wherein a first plane is provided on the outer circumferential side of the positioning pin, and a second plane is provided on the inner sidewall of the positioning groove, wherein the first plane and the second plane abut against each other to prevent the positioning pin from rotating.

[0013] According to a first aspect of the present invention, a positioning plate for a camera module is provided, wherein a plurality of positioning pins are located in a second receiving groove.

[0014] According to a first aspect of the present invention, a positioning plate for a camera module is provided, wherein the second receiving groove has a first sidewall, a second sidewall and a third sidewall, the first sidewall and the second sidewall are perpendicular to each other, the second sidewall and the third sidewall are perpendicular to each other, and the ends of anisotropic conductive films are restricted between the first sidewall, the second sidewall and the third sidewall.

[0015] According to a first aspect embodiment of the present invention, a positioning plate for a camera module has a chamfered surface connected to the top of the first sidewall, the second sidewall, and the third sidewall. The chamfered surface is used to guide the end of the anisotropic conductive film into the second receiving groove.

[0016] According to a first aspect of the present invention, a positioning plate for a camera module is provided, wherein one of the positioning pins is disposed opposite to the second sidewall.

[0017] A test fixture according to a second aspect of the present invention includes a positioning plate for a camera module as described in any one of the above-described embodiments.

[0018] A test fixture according to an embodiment of the present invention has at least the following beneficial effects:

[0019] This invention utilizes a test fixture with a positioning plate. When the suction head places the camera module above the positioning plate, the guide portion is positioned at the top of the positioning pin, bringing it closer to the camera. The guide portion tapers along the height of the positioning pin. As the camera module falls freely, the anisotropic conductive film moves along the guide portion, allowing it to smoothly descend vertically along the positioning pin.

[0032] The following description, in conjunction with the accompanying drawings, describes a positioning plate and testing fixture for a camera module according to an embodiment of the present invention.

[0033] Reference Figure 1 The present invention aims to provide an embodiment of a positioning plate and a testing fixture for a camera module 100.

[0034] In the structure of the camera module 100, the camera module 100 includes a camera body 110 and an anisotropic conductive film 120 connected to the camera body 110. The anisotropic conductive film 120 has a connector 130 at its end.

[0035] A positioning plate and test fixture for a camera module 100 according to an embodiment of the present invention includes a plate body 140, positioning pins 170, and a guide portion 180. The top of the plate body 140 has a first receiving groove 150 and a second receiving groove 160, which are connected. The first receiving groove 150 is used to receive the camera body 110, and the second receiving groove 160 is used to receive the anisotropic conductive film 120. A plurality of positioning pins 170 are provided, which are connected to the top of the plate body 140 and arranged along the outer periphery of the anisotropic conductive film 120 to limit the horizontal position of the anisotropic conductive film 120. The guide portion 180 is provided on the top of the positioning pins 170 and is gradually tapered along the height direction of the positioning pins 170. The guide portion 180 is used to guide the anisotropic conductive film 120 to move downward along the vertical direction of the positioning pins 170.

[0036] Understandably, by setting a positioning plate, the positioning plate has a plate body 140, the top of which defines a first receiving groove 150 for accommodating the camera body 110 and a second receiving groove 160 for accommodating the anisotropic conductive film 120. Furthermore, by making the positioning plate have a positioning pin 170 and a guide portion 180, when the suction head places the camera module 100 above the positioning plate, the guide portion 180 is at the top of the positioning pin 170, making the guide portion 180 closer to the camera position. Moreover, the guide portion 180 has a structure that tapers along the height direction of the positioning pin 170, thus enabling the camera to... When the head module 100 falls freely, the anisotropic conductive film 120 moves along the guide portion 180, allowing the anisotropic conductive film 120 to smoothly move downwards along the vertical direction of the positioning pins 170. Several positioning pins 170 can precisely limit the position of the anisotropic conductive film 120, avoiding the problem of the connector 130 of the anisotropic conductive film 120 shifting position when the camera module 100 falls freely. This ensures that the connector 130 of the anisotropic conductive film 120 will not be damaged when it docks with the socket of the test fixture during testing, thus improving the reliability of the test and greatly reducing the number of defective products generated during the test.

[0037] In some embodiments of this utility model, the guide portion 180 can be a conical structure.

[0038] Understandably, the conical structure has a smooth surface and low friction. When the camera module 100 falls freely, the anisotropic conductive film 120 moves along the guide portion 180, which helps guide the anisotropic conductive film 120 to move smoothly down along the vertical direction of the positioning pin 170, thus avoiding the phenomenon that the anisotropic conductive film 120 cannot move when it moves along the guide portion 180.

[0039] Specifically, the guide part 180 can also be a hemispherical structure or a pyramidal structure. Those skilled in the art can choose to set it according to the actual situation, and this embodiment does not limit it.

[0040] In some embodiments of this utility model, a plurality of positioning pins 170 may be located within the second receiving groove 160. It is understood that those skilled in the art can arrange the positions of the positioning pins 170 according to the actual situation.

[0041] In some embodiments of this utility model, a positioning groove 190 is provided in the second receiving groove 160, and the positioning pin 170 and the positioning groove 190 are positioned together. It can be understood that the positioning groove 190 can be machined on the first receiving groove 150 using machining equipment, and the positioning pin 170 is installed in the positioning groove 190, so that the position and size of the positioning pin 170 are more accurate, and the dimensional tolerance between the positioning pin 170 and the outer side of the anisotropic conductive film 120 is small.

[0042] In some embodiments of this utility model, reference is made to Figure 3 , Figure 4 and Figure 5 The bottom wall of the positioning groove 190 is provided with a through hole 200, and a bolt 210 is inserted into the through hole 200. The positioning pin 170 is provided with a threaded hole 220. After the bolt 210 passes through the through hole 200, it is tightened into the threaded hole 220.

[0043] It is understandable that the positioning pin 170 can be fixed on the plate 140 by tightening the bolt 210 with the threaded hole 220, without the need to use the interference fit between the positioning pin 170 and the positioning groove 190. This avoids the problem of the positioning pin 170 being deformed by using tools to knock the positioning pin 170 into the positioning groove 190.

[0044] In some embodiments of this utility model, a first plane 230 is provided on the outer circumferential side of the positioning pin 170, and a second plane 240 is provided on the inner sidewall of the positioning groove 190. The first plane 230 and the second plane 240 abut against each other to prevent the positioning pin 170 from rotating.

[0045] Understandably, in order to prevent the locating pin 170 from rotating during the tightening of the bolt 210 and the threaded hole 220, the first plane 230 and the second plane 240 between the locating pin 170 and the locating groove 190 can be used to abut against each other to prevent the locating pin 170 from rotating, making it easier to tighten the bolt 210 and the threaded hole 220.

[0046] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 The second receiving groove 160 has a first sidewall 250, a second sidewall 260 and a third sidewall 270. The first sidewall 250 and the second sidewall 260 are perpendicular to each other, and the second sidewall 260 and the third sidewall 270 are perpendicular to each other. The ends of the anisotropic conductive film 120 are restricted between the first sidewall 250, the second sidewall 260 and the third sidewall 270. Based on this, the end position of the anisotropic conductive film 120 is further restricted by the first sidewall 250, the second sidewall 260 and the third sidewall 270 to ensure that the connector 130 of the anisotropic conductive film 120 is accurately positioned.

[0047] In some embodiments of this utility model, the tops of the first sidewall 250, the second sidewall 260, and the third sidewall 270 are all connected to a chamfered surface 280. The chamfered surface 280 is used to guide the end of the anisotropic conductive film 120 into the second receiving groove 160. Based on this, by setting the chamfered surface 280, the opening formed at the tops of the first sidewall 250, the second sidewall 260, and the third sidewall 270 is enlarged, avoiding the end of the anisotropic conductive film 120 from falling off-center.

[0048] In some embodiments of this utility model, one of the positioning pins 170 is disposed opposite to the second sidewall 260. Based on this, the positioning pin 170 abuts against the anisotropic conductive film 120 away from the second sidewall 260 to prevent the anisotropic conductive film 120 from deviating from the second sidewall 260, thereby ensuring that the connector 130 of the anisotropic conductive film 120 is in the correct position.

[0049] An embodiment of this utility model also proposes a test fixture, including the positioning plate and test plate described in the above embodiments.

[0050] Understandably, when the suction head places the camera module 100 above the positioning plate, the guide portion 180 is on top of the positioning pin 170, bringing the guide portion 180 closer to the camera. Furthermore, the guide portion 180 has a tapering structure along the height of the positioning pin 170. When the camera module 100 falls freely, the anisotropic conductive film 120 moves along the guide portion 180, allowing it to smoothly move downwards along the vertical direction of the positioning pin 170. Several positioning pins 170 can precisely restrict the position of the anisotropic conductive film 120, preventing the connector 130 of the anisotropic conductive film 120 from shifting position when the camera module 100 falls freely. The test board can have a socket, and the test board and positioning plate fit together vertically. The socket on the test board and the connector 130 of the anisotropic conductive film 120 can precisely align, preventing damage to the connector 130 of the anisotropic conductive film 120 and avoiding damage to the plug of the test fixture due to poor alignment, thus improving the service life of the test fixture.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
