Description

Technical Field

[0001] This application relates to the field of semiconductor technology, and more specifically, to a capping device and apparatus. Background Technology

[0002] Current image sensors typically have an optical glass layer over the photosensitive area, which effectively protects the sensor's working area from contamination and extends its lifespan. However, in many applications, image detectors require the removal of the optical glass to achieve optimal imaging results or specific shooting functions. The optical glass and sensor encapsulation are usually bonded together with UV adhesive; therefore, the core idea behind opening the cover is to use physical or chemical methods to disable the adhesive, thus allowing the cover to be opened.

[0003] The current mainstream method for opening the cover is to heat the sensor evenly to soften or melt the glue and then use a blade to pry open the glass. Since this requires operation at high temperatures, the overall operation is difficult and carries a high risk of burns and blade punctures. At the same time, using a blade to pry the glass also has a high probability of causing the glass to break and damaging the sensor surface. Utility Model Content

The supporting structure is used to abut against the side wall of the second component along the second direction. A transmission component is disposed on the side of the fixed fixture away from the heating base, and one end of the transmission component contacts the side wall of the movable fixture, for pushing the movable fixture relative to the fixed fixture along the second direction along the side wall of the movable fixture, so that the abutment structure pushes the second component away from the first component along the second direction.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] Currently, there are three main methods for opening the sensor cover: 1. Solvent method: This method uses chemical solvents to penetrate and dissolve the adhesive that fixes the protective glass. However, solvents are generally highly corrosive and volatile, posing a high risk during operation. They can release toxic gases, and the resulting byproducts can contaminate the sensor and harm the health of operators.

[0026] 2. Laser vaporization: This method uses a short-pulse laser to scan the sealed adhesive area, causing the adhesive to carbonize and become ineffective, allowing the cap to be opened at room temperature. This method requires precise laser focusing on an adhesive layer only micrometers thick, placing extremely high demands on the precision of the mechanical system. The high equipment cost and complex parameter adjustments make this technology difficult to widely use. Furthermore, professional protective measures are required during laser operation to prevent injury to operators, resulting in high costs.

[0027] 3. High-temperature method: This method involves uniformly heating the sensor to soften or melt the adhesive, causing it to fail. This is currently the most common method. After heating, the glass needs to be pried open with a blade. Because it requires operation at high temperatures, the overall operation is difficult, with a high risk of burns and blade punctures. At the same time, using a blade to pry the glass also has a high probability of causing the glass to break, damaging the sensor surface.

[0028] To address the aforementioned problems, this utility model provides a novel lid-opening device 100 and equipment, which can perform the lid-opening action efficiently and safely, while also being lower in cost and easier to operate. It should be noted that, unless otherwise specified, the features in the embodiments of this application can be combined with each other.

[0029] See Figures 1 to 5 This utility model provides a lid opening device 100, which can perform lid opening actions efficiently and safely, is simple to operate, and does not require operators to directly contact high-temperature parts, thus having low operational risks and better safety.

[0030] The cover-opening device 100 provided in this embodiment of the utility model is used to separate a first component and a second component that are laminated and bonded together along a first direction. The cover-opening device 100 includes a heating base 110, a fixed fixture 120, a movable fixture 130, and a transmission component 140. The heating base 110 can be externally connected to a heating component to achieve contact heating. The fixed fixture 120 is detachably mounted on the heating base 110, and a limiting structure is provided on the side of the fixed fixture 120 away from the heating base 110. The limiting structure is used to limit the first component along a second direction. The movable fixture 130 is movably mounted on the side of the fixed fixture 120 away from the heating base 110, and a supporting structure is provided on the side of the movable fixture 130 close to the fixed fixture 120. The supporting structure is used to abut against the side wall of the second component along the second direction. The transmission component 140 is disposed on the side of the fixed fixture 120 away from the heating base 110, and one end of the transmission component 140 contacts the side wall of the movable fixture 130, for pushing the movable fixture 130 relative to the fixed fixture 120 along the side wall of the movable fixture 130 in the second direction, so that the abutment structure pushes the second component away from the first component in the second direction.

[0031] It should be noted that the opening device 100 here can be used to open the image sensor 200. The first component and the second component are the optical glass sheet 230 and the ceramic package 210 of the image sensor 200, respectively. For example, the first component is the optical glass sheet 230 of the image sensor 200, and the second component is the ceramic package 210 of the image sensor 200. The optical glass sheet 230 can be attached to the ceramic package 210 along the first direction. The adhesive between the optical glass sheet 230 and the ceramic package 210 can be a conventional adhesive such as UV glue, which will lose its adhesive properties when heated. Of course, in other preferred embodiments of this utility model, the first component and the second component can also be other laminated adhesive structures, such as a heat sink and a package. In actual use, the fixing fixture 120 is first installed on the heating base 110, and then the image sensor 200 is installed on the fixing fixture 120, so that the optical glass sheet 230 of the image sensor 200 is fixed by the limiting structure. Next, the movable fixture 130 is installed, and its supporting structure abuts against the side wall of the ceramic package 210. Finally, the transmission component 140 is installed, allowing it to connect with the movable fixture 130 and transmit force. After assembly, the heating base 110 can be used to heat the optical glass sheet 230 to the required temperature, and the optical glass sheet 230 will be heated through heat conduction via the fixed fixture 120. At high temperatures, the adhesive between the optical glass sheet 230 and the ceramic package 210 will fail. At this time, force is applied to the transmission component 140 manually or by an external power source, allowing the transmission component 140 to push the movable fixture 130 relative to the fixed fixture 120 in the second direction via the side wall. This causes the supporting structure to push the ceramic package 210 away from the optical glass sheet 230 in the second direction, thus opening the package. Since the difference in the vertical direction between the force application position of the transmission component 140 (acting on the movable fixture 130) and the force application position of the supporting structure (acting on the ceramic package 210) is small, the torsional torque is smaller, thus preventing the movable fixture 130 from flipping. The second direction is perpendicular to the first direction. The first direction refers to the direction perpendicular to the optical glass plate 230, such as a vertical direction, and the second direction refers to the direction parallel to the optical glass plate 230, such as a horizontal direction.

[0032] During the opening process, the optical glass plate 230 is fixed by the limiting structure of the fixed fixture 120, and the ceramic package 210 is pushed by the supporting structure of the movable fixture 130. The movable fixture 130 is driven by the transmission component 140 of the intermediate transmission. Therefore, when force is applied, it does not directly act on the movable fixture 130 or the ceramic package 210, effectively avoiding the risk of burns in conventional high-temperature methods. When the lid is opened, the ceramic package 210 is subjected to force and moves along the second direction, which can effectively prevent the glass from breaking and damaging the sensor surface during the opening process. Therefore, the opening action can be carried out efficiently and safely. The whole process is simple to operate and does not require the operator to directly contact the high-temperature parts, resulting in low operational risk and better safety.

[0033] In some embodiments, the limiting structure includes a fixing groove 121 for accommodating the first component, and the depth of the fixing groove 121 is less than or equal to the thickness of the first component along a first direction. Specifically, the shape of the fixing groove 121 is adapted to the shape of the first component; for example, the fixing groove 121 may be rectangular and adapted to the shape and size of the optical glass sheet 230, so that the optical glass sheet 230 can be precisely fitted into the fixing groove 121, and the fixing groove 121 limits the optical glass sheet 230 in a second direction. Preferably, the depth of the fixing groove 121 is equal to the thickness of the optical glass sheet 230, thereby preventing the fixing groove 121 from simultaneously limiting the ceramic package 210.

[0034] It should be noted that the size of the fixing groove 121 can be set according to the size of the first component, thus ensuring applicability. Of course, in other preferred embodiments of this utility model, the limiting structure can also adopt other structural forms such as fixing protrusions or fixing fences to fix the first component.

[0035] See also Figure 4 and Figure 5 In some embodiments, the abutment structure includes an abutment step 131, which has an abutment surface 132 for abutting against the sidewall of the second component in a second direction. Specifically, the middle of the fixing fixture 120 is partially recessed, forming a receiving space capable of accommodating the second component. The abutment step 131 is formed at the edge of this receiving space, and the bottom surface of the abutment step 131 can fit against the top surface of the fixing fixture 120 and slide along the top surface of the fixing fixture 120 during the opening process, thereby achieving translation. The sidewall of the abutment step 131 forms the abutment surface 132, which can abut against the sidewall of the ceramic package 210, thereby pushing the ceramic package 210 to detach from the optical glass sheet 230.

[0036] See also Figure 1 , Figure 4 and Figure 6In some embodiments, a fixed seat 122 is provided on the edge of the side surface of the fixed fixture 120 away from the heating base 110. The movable fixture 130 is disposed on one side of the fixed seat 122. The fixed seat 122 has a limiting screw hole 123 with an opening along the second direction. The transmission component 140 is threadedly assembled in the limiting screw hole 123. Specifically, the fixed seat 122 protrudes in the direction away from the heating base 110, and the transmission component 140 can be a screw threadedly assembled in the limiting screw hole 123. When force is applied, the transmission component 140 can be rotated directly. Under the action of the limiting screw hole 123 and the fixed seat 122, the transmission component 140 can move along the second direction while rotating, thereby pushing the movable fixture 130 to translate. Through the mating structure of the threaded screw, the transmission component 140 can rotate and translate at the same time. Compared with the direct abutment and push method, the transmission process is more stable and reliable, and the push feed is also easier to control.

[0037] In some embodiments, the movable tooling 130 is provided with a positioning hole 133 on the side near the fixed base 122, and the transmission member 140 extends into the positioning hole 133. Specifically, the side wall of the movable tooling 130 is provided with a positioning hole 133, the diameter of which is slightly larger than the outer diameter of the transmission member 140, so that the end of the transmission member 140 can be just inserted into the positioning hole 133, ensuring mutual restraint between the transmission member 140 and the movable tooling 130 and preventing the movable tooling 130 from shifting.

[0038] Furthermore, an observation groove 134 is provided on the edge of the movable fixture 130 near the fixed base 122. This observation groove 134 communicates with the positioning hole 133. The transmission component 140 extends into the observation groove 134 through the positioning hole 133 and abuts against the inner wall of the observation groove 134. By providing the observation groove 134, it is possible to observe in a timely manner whether the transmission component 140 is in place, and to effectively ensure that the abutment position between the transmission component 140 and the movable fixture 130 is located at the end of the transmission component 140, thus preventing the transmission component 140 from getting stuck in the movable fixture 130.

[0039] See also Figure 1 and Figure 6In some embodiments, the opening device 100 further includes an elastic connecting component 150. The elastic connecting component 150 is disposed on the fixed fixture 120 and elastically abuts against the edge of the movable fixture 130, for applying an elastic force toward the fixed fixture 120 in a first direction to the movable fixture 130. Specifically, there are multiple elastic connecting components 150, which are installed on the fixed fixture 120 in a first direction and can elastically abut against the two side edges of the movable fixture 130, ensuring that the movable fixture 130 can always fit against the surface of the fixed fixture 120 during the opening process, thereby ensuring that the abutting surface 132 of the abutting step 131 always abuts against the side wall of the ceramic package 210, ensuring effective pushing.

[0040] In some embodiments, the resilient connection assembly 150 includes a fastener 151 and an elastic element 152. A fixing hole 124 is provided on the side of the fixing fixture 120 away from the heating base 110. The fastener 151 is fitted into the fixing hole 124, and the elastic element 152 is sleeved on the fastener 151 and elastically abuts against the edge of the movable fixture 130. Specifically, the fastener 151 can be a screw, and the elastic element 152 can be a spring. The spring is sleeved on the screw and elastically abuts against the edge of the movable fixture 130. It should be noted that the spring here is in a compressed state, capable of providing a downward elastic force to the two sides of the movable fixture 130, causing the movable fixture 130 to press down onto the fixing fixture 120.

[0041] Furthermore, the movable fixture 130 is also provided with a limiting platform 135 at its edge. The limiting platform 135 has a limiting guide hole 136 extending in the second direction, and the fastener 151 passes through the limiting guide hole 136. Specifically, the limiting guide hole 136 is an oblong hole, and the long axis of the limiting guide hole 136 is in the second direction. The fastener 151 passes through the limiting guide hole 136 and is assembled in the fixing hole 124. Through the limiting guide hole 136, the movement trajectory of the movable fixture 130 can be limited in the second direction, ensuring the smoothness and controllability of the opening action.

[0042] In some embodiments, a positioning groove 125 is provided on the side surface of the fixing fixture 120 near the heating base 110, and the heating base 110 is assembled in the positioning groove 125. Specifically, the shape of the positioning groove 125 is adapted to the shape of the heating base 110, and can just accommodate the heating base 110. By providing the positioning groove 125, on the one hand, the fixing fixture 120 can be thinned, so that the distance between the heating base 110 and the fixing groove 121 is reduced, which is conducive to rapid heat conduction. On the other hand, the positioning between the fixing fixture 120 and the heating base 110 can be achieved, ensuring the stability of the overall structure.

[0043] It should be noted that both the heating base 110 and the fixing fixture 120 are made of materials with good thermal conductivity, such as copper, iron, or other metals with good thermal conductivity. The heating base 110 can be connected to an external heater to provide the temperature required during the opening process. This temperature needs to be greater than the thermal failure temperature of the adhesive. The bottom side of the fixing fixture 120 is in direct contact with the heating base 110 for heat transfer.

[0044] This utility model embodiment also provides a lid-opening device, including a force-applying component (not shown) and the aforementioned lid-opening device 100. The lid-opening device 100 includes a heating base 110, a fixed fixture 120, a movable fixture 130, and a transmission component 140. The heating base 110 can be externally connected to a heating component to achieve contact heating. The fixed fixture 120 is disposed on the heating base 110, and a limiting structure is provided on the side of the fixed fixture 120 away from the heating base 110. The limiting structure is used to fix the first component. The movable fixture 130 is movably disposed on the side of the fixed fixture 120 away from the heating base 110, and a supporting structure is provided on the side of the movable fixture 130 close to the fixed fixture 120. The supporting structure is used to abut against the side wall of the second component along a second direction. The transmission component 140 is disposed on the side of the fixed fixture 120 away from the heating base 110, and one end of the transmission component 140 is connected to the movable fixture 130. It is used to drive the movable fixture 130 to move relative to the fixed fixture 120 in a second direction, so that the supporting structure pushes the second component away from the first component in the second direction. A force-applying component is connected to the end of the transmission component 140 away from the movable fixture 130, and is used to drive the transmission component 140 to move or rotate relative to the fixed base 122.

[0045] It should be noted that the force-applying component here can be a wrench, which can be used to manually turn the transmission component 140, thereby realizing the helical feed of the transmission component 140.

[0046] The actual steps for opening the lid during processing are as follows: Step 1: Fix the image sensor 200 on the cover opening device 100 and install the movable fixture 130.

[0047] Specifically, the fixed fixture 120 can be fixed to the heating base 110, and then the image sensor 200 can be placed in the fixing groove 121 of the fixed fixture 120, wherein the optical glass surface contacts the fixed fixture 120, and the movable fixture 130 is fixedly pressed onto the fixed fixture 120 by fasteners 151 and springs.

[0048] Step 2: Heating.

[0049] Specifically, first control the temperature of the heating base 110 to 90℃ and set the heating time to 20 minutes. After 20 minutes, control the temperature of the heating base 110 to 200℃ and set the heating time to 15 minutes. At this time, the bonding adhesive can be quickly deactivated.

[0050] Step 3: Open the lid.

[0051] The transmission component 140, in conjunction with the positioning screw hole, forms a screw mechanism that presses the movable fixture 130 at a constant speed. The movable fixture 130 and the fixed fixture 120 undergo relative displacement, which drives the ceramic package 210 of the image sensor 200 to detach from the optical glass plate 230, thereby separating the two and completing the opening of the cover.

[0052] Through the above technical solution, the lid-opening device 100 and equipment provided in this utility model embodiment have a fixed fixture 120 set on a heating base 110, which is used to achieve heating. A limiting structure is also provided on the side of the fixed fixture 120 away from the heating base 110, which can fix the first component. A movable fixture 130 is movably set on the side of the fixed fixture 120 away from the heating base 110, and the movable fixture 130 abuts against the side wall of the second component through a supporting structure. A transmission component 140 can be connected to the movable fixture 130 and drive the movable fixture 130 to move relative to the fixed fixture 120, thereby causing the supporting structure to push the second component away from the first component, completing the lid opening. Compared with the prior art, this utility model embodiment, through the setting of the fixed fixture 120 and the movable fixture 130, and using the transmission component 140 to achieve the action, can perform the lid opening action efficiently and safely. The operation is simple, and there is no need for the operator to directly contact the high-temperature parts, resulting in low operational risk and better safety. Compared to chemical solvents and laser vaporization methods, the opening method in this invention is more economical and safer, and can cover the opening needs of sensors of all sizes.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
