Description

Technical Field

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

[0002] In the design of an autofocus camera, the camera module includes a lens barrel assembly 171 and a substrate 172. The lens barrel assembly 171 is connected to the substrate 172. The lens barrel assembly 171 has a resin lens barrel and a lens barrel motor. Since the resin lens barrel needs to move up and down slightly along the Z-axis under the control of the lens barrel motor, in order to enable the resin lens barrel and the lens barrel motor to move relative to each other, the air pressure inside the lens barrel assembly 171 needs to be stable. Therefore, a ventilation space needs to be provided between the lens barrel assembly 171 and the substrate 172. The ventilation space allows the inside of the camera module to communicate with the outside, thereby maintaining the air pressure balance inside and outside the camera module.

[0003] When manufacturing camera modules, automated equipment is needed to move the camera modules. Since the pick-and-place technology has an advantage in terms of handling speed, a pick-and-place jig and a moving module are used together to pick up and transfer the camera modules.

[0004] According to the structure of the camera module 170, the suction fixture includes a suction head with an adsorption hole 150. The suction head can adsorb the substrate 172 of the camera module 170 through the adsorption hole 150. In order to avoid interference between the suction head and the lens barrel assembly 171, the suction head needs to be provided with a clearance space to avoid the lens barrel assembly 171.

[0005] However, when the existing suction fixture picks up the camera module 170, foreign matter accumulates inside the suction hole 150 of the suction head. Furthermore, the clearance space forms a relatively sealed space, and there are tolerances in the contact between the suction head and the substrate 172, resulting in a small gap between them. Additionally, the ventilation space between the lens barrel assembly 171 and the substrate 172 is located within the clearance space, causing the suction hole 150 and the clearance space to be in a conductive state. This makes it easy for the inside of the camera module 170 to be in a vacuum state. (Refer to...) Figure 1 When the suction fixture lowers the camera module 170, the gas in the suction fixture is released from the suction hole 150. Since the vacuum inside the camera module 170 is relatively large, the gas containing foreign matter released from the suction hole 150 can easily enter the camera module 170, causing the camera module 170 to malfunction. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a suction fixture for camera modules. When suctioning a camera module, it can reduce the vacuum level inside the camera module, reduce the exchange of gas between the inside and outside of the camera module, and reduce the entry of foreign objects into the camera module, thereby reducing the problem of camera module failure.

[0007] A suction fixture for a camera module according to an embodiment of the present invention includes: a suction body having an adsorption part for adsorbing a substrate; a clearance cavity disposed on the suction body for accommodating a lens barrel assembly; and a balancing channel disposed on the suction body, the balancing channel being able to connect the clearance cavity to the outside of the suction fixture to balance the internal and external air pressure of the clearance cavity.

[0008] A camera module suction fixture according to an embodiment of the present utility model has at least the following beneficial effects:

[0009] This invention, by setting up a suction body, a clearance cavity, and a balancing channel, allows the suction body to contact the substrate during camera module suction. The clearance cavity accommodates the clearance lens assembly, enabling the suction body to smoothly suction the camera module. Due to the tolerance between the contact surface between the suction body and the substrate, the suction body evacuates the clearance cavity. The balancing channel connects the clearance cavity to the external air pressure, making the internal air pressure of the clearance cavity the same as the external ambient air pressure. This reduces the vacuum level inside the camera module during suction and minimizes gas exchange between the camera module and the outside. Thus, on the one hand, when the suction fixture lowers the camera module, the vacuum state of the suction fixture is released, and the internal pressure of the camera module is approximately the same as atmospheric pressure, preventing negative pressure from being generated inside the camera module. This makes it difficult for foreign objects to enter the camera module, and also makes it difficult for foreign-laden gas released by the suction fixture to enter the camera module, reducing the risk of camera module failure. On the other hand, the balancing channel can greatly reduce the entry of foreign objects from the suction fixture into the camera module, effectively reducing the frequency of equipment inspection and cleaning, systematically saving manpower and improving equipment operating efficiency.

[0010] According to an embodiment of the present invention, a suction fixture for a camera module is provided, wherein multiple suction parts are provided, and the multiple suction parts are arranged along the outer side of the avoidance cavity.

[0011] According to an embodiment of the present invention, a suction fixture for a camera module is provided, wherein a balance channel is provided between at least two adjacent suction parts.

[0012] According to an embodiment of the present invention, a camera module suction fixture is provided. When the suction part suctions the camera module, the avoidance cavity exchanges gas with the external environment through the balance channel to reduce the vacuum level inside the camera module.

[0013] According to an embodiment of the present invention, a suction fixture for a camera module is provided, wherein the suction part has an abutting surface for abutting against the surface of a substrate.

[0014] According to an embodiment of the present invention, a suction fixture for a camera module is provided, wherein the suction part has a recess on the side near the contact surface, and the recess is used to form the balance channel.

[0015] According to an embodiment of the present invention, a suction fixture for a camera module is provided, wherein the suction part is provided with at least one suction hole, and at least one suction hole is arranged on the contact surface.

[0016] According to an embodiment of the present invention, a suction fixture for a camera module is provided, wherein the suction hole extends vertically along the vertical direction of the suction body.

[0030] The following description, in conjunction with the accompanying drawings, describes a suction fixture for a camera module according to an embodiment of the present invention.

[0031] Reference Figure 2The present invention aims to provide an embodiment of a suction fixture for a camera module.

[0032] A suction fixture for a camera module 170 according to an embodiment of the present invention includes a suction body, a clearance cavity 120, and a balancing channel 130. The suction body has an adsorption part 140 for adsorbing a substrate 172. The clearance cavity 120 is disposed in the suction body and is used to accommodate a lens barrel assembly 171. The balancing channel 130 is disposed in the suction body and can connect the clearance cavity 120 to the outside of the suction fixture to balance the internal and external air pressure of the clearance cavity 120.

[0033] Understandably, by setting up the suction body, the clearance cavity 120, and the balancing channel 130, when suctioning the camera module 170, the suction body contacts the substrate 172 using the adsorption part 140, and the clearance cavity 120 can accommodate the clearance lens barrel assembly 171, allowing the adsorption part 140 to smoothly suction the camera module 170. Due to the tolerance between the contact surface between the adsorption part 140 and the substrate 172, the adsorption part 140 will evacuate the clearance cavity 120. The balancing channel 130 connects the clearance cavity 120 to the external air pressure, making the internal air pressure of the clearance cavity 120 the same as the external ambient air pressure, reducing the vacuum degree inside the camera module 170 when suctioning the camera module 170, and reducing the risk of damage to the camera module. The internal and external gas exchange of the assembly 170 allows for two main benefits. First, when the suction fixture lowers the camera module 170, the vacuum state of the suction fixture is released, and the internal pressure of the camera module 170 is approximately the same as atmospheric pressure. This prevents negative pressure from being generated inside the camera module 170, making it difficult for external foreign objects to enter the camera module 170, and also making it difficult for foreign objects released by the suction fixture to enter the camera module 170, thus reducing the risk of camera module 170 failure. Second, the balancing channel 130 can greatly reduce the amount of foreign objects from the suction fixture entering the camera module 170, effectively reducing the frequency of equipment inspection and cleaning, systematically saving manpower and improving equipment operating efficiency.

[0034] In some embodiments of this utility model, multiple adsorption parts 140 are provided, and the multiple adsorption parts 140 are arranged along the outer side of the avoidance cavity 120.

[0035] It is understandable that by setting multiple adsorption parts 140, the multiple adsorption parts 140 can simultaneously adsorb the camera module 170. Furthermore, by arranging the multiple adsorption parts 140 along the outer side of the avoidance cavity 120, it is ensured that the adsorption body 100 firmly adsorbs the camera module 170, thus avoiding the problem of the camera module 170 falling off during adsorption.

[0036] In some embodiments of this utility model, a balance channel 130 is provided between at least two adjacent adsorption parts 140. Therefore, when the camera module 170 is adsorbed, the multiple balance channels 130 can greatly reduce the vacuum level inside the camera module 170.

[0037] In some embodiments of this utility model, when the adsorption part 140 picks up the camera module 170, the avoidance cavity 120 exchanges gas with the external environment through the balance channel 130 to reduce the vacuum inside the camera module 170. This prevents the formation of negative pressure inside the camera module 170 when the adsorption part 140 puts down the camera module 170, and reduces the entry of foreign objects into the camera module 170.

[0038] In some embodiments of this utility model, the adsorption part 140 has an abutment surface 110, which is used to abut against the surface of the substrate 172. Therefore, by providing the abutment surface 110 and using the abutment surface 110 to contact the surface of the substrate 172, it is beneficial for the adsorption part 140 to fit tightly against the substrate 172.

[0039] In some embodiments of this utility model, the adsorption part 140 is provided with a recess on the side near the contact surface 110, and the recess is used to form a balance channel 130.

[0040] It is understandable that by setting the recess close to the contact surface 110, the balance channel 130 is closer to the contact position between the adsorption part 140 and the substrate 172, so that when the adsorption part 140 picks up the camera module 170, the inside of the camera module 170 is not easily in a vacuum state.

[0041] In addition, the balance channel 130 has a concave structure, which makes the balance channel 130 easier and more convenient to process.

[0042] In some embodiments of this utility model, the adsorption part 140 is provided with at least one adsorption hole 150, and the at least one adsorption hole 150 is arranged on the contact surface 110. The number of adsorption holes 150 can be designed according to the needs of use to change the adsorption capacity of the adsorption head 100.

[0043] In some embodiments of this utility model, reference is made to Figure 3 The adsorption hole 150 extends vertically along the vertical direction of the adsorption body. Therefore, the adsorption hole 150 has a straight-through structure, which makes it less likely to trap dust and foreign objects, thus reducing the entry of foreign objects into the camera module 170.

[0044] In some embodiments of this utility model, reference is made to Figure 4An arc-shaped surface 180 is provided on the side of the adsorption part 140 near the avoidance cavity 120. The arc-shaped surface 180 matches the outer periphery of the lens barrel assembly 171. Therefore, by providing the arc-shaped surface 180, interference between the adsorption part 140 and the outer periphery of the lens barrel assembly 171 can be avoided.

[0045] In some embodiments of this utility model, the suction body has a connecting plate 160, which is connected to the suction part 140, thereby facilitating the connection and fixation of the suction fixture to external components through the connecting plate 160.

[0046] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. 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.
