Description

Technical Field

[0001] This invention relates to the field of lead frame manufacturing technology, and more particularly to a water washing device for lead frame manufacturing. Background Technology

[0002] The main purpose of washing leadframes is to thoroughly remove electroplating residue, oil, dust, and other contaminants from their surface to ensure they meet the required cleanliness standards. A clean surface significantly improves the bonding strength of the package and the long-term reliability of the product, making it a crucial step in ensuring overall packaging quality. During the washing process, the leadframes are evenly placed in a dedicated carrier box and immersed in an ultrasonic cleaner. The process typically involves sequentially using cleaning fluid and water, effectively removing metal debris, flux, and other contaminants adhering to the leadframe surface through ultrasonic cavitation. However, because the carrier box physically blocks the lower edge of the leadframe during cleaning, this area can become a cleaning blind spot, making it difficult to completely remove residual contaminants. Unremoved contaminants (such as metal debris or chemical residues) can lead to poor bonding between the leadframe and the packaging material in subsequent processes, reducing bonding strength and even causing delamination, corrosion, or electrical faults after packaging, ultimately affecting product reliability and lifespan. Summary of the Invention

[0003] This invention provides a water washing device for lead frame production, which overcomes the shortcomings of existing technologies that have blind spots on the surface of the lead frame during cleaning, making it difficult to completely remove contaminants from the surface of the lead frame.

[0004] The technical implementation of the present invention is as follows: a water washing device for lead frame production, comprising: an ultrasonic cleaner, a main board and a sub-board, wherein the main board and the sub-board are both located inside the ultrasonic cleaner, a top plate is fixedly connected to the upper part between the main board and the sub-board, and a bottom plate that contacts the ultrasonic cleaner is slidably connected to the lower side of the main board and the sub-board together. Multiple support members and multiple supporting members are respectively embedded on the opposing sides of the main board and the sub-board. The number of support members and the supporting members are equal and they are evenly distributed at equal intervals. A support portion is provided on the upper side of the support member, and a support portion and a swing arm portion are provided on the supporting member. The support portion and the support portion are used together to support the lead frame. A main fixing clamp is fixedly connected to the swing arm portion. All the main fixing clamps are detachably connected to a main connecting rod that is slidably connected to the sub-board. The main connecting rod is fixedly connected to the bottom plate. A power mechanism is provided on the bottom plate for controlling the swing of the supporting portion to change the support position of the support members and the supporting members on the lead frame.

[0005] Furthermore, the power mechanism includes: two L-shaped components, a main liquid bladder, and two auxiliary liquid bladders. The two L-shaped components are slidably connected within the base plate and respectively contact the main plate and the auxiliary plate to maintain a constant distance between the main plate and the auxiliary plate and the base plate. The main liquid bladder is fixedly connected within the base plate, and the auxiliary liquid bladders are fixedly connected within the base plate and to adjacent L-shaped components. The auxiliary liquid bladders are connected to the main liquid bladders via conduits. Both the main liquid bladders and the auxiliary liquid bladders contain damping fluid. The base plate is provided with a control component for regulating the flow rate of the damping fluid from the main liquid bladders to the auxiliary liquid bladders.

[0006] Furthermore, the elastic coefficient of the main liquid bladder is greater than that of the secondary liquid bladder.

[0007] Furthermore, the control component includes a U-shaped member and an adjusting bolt. The U-shaped member is slidably connected to the base plate and is used to squeeze the conduit between the main liquid bladder and the auxiliary liquid bladder. The adjusting bolt is slidably connected to the U-shaped member and threadedly connected to the base plate. The adjusting bolt is used to control the relative position of the U-shaped member and the base plate.

[0008] Furthermore, the upper side of the support portion is provided with evenly distributed grooves.

[0009] Furthermore, the support portion and the bearing portion are coated with a chromium nitride coating to improve surface hardness and smoothness.

[0010] Furthermore, the support member is provided with a swinging part, the swinging part is fixedly connected to a secondary fixing clamp, the secondary fixing clamp is slidably connected to the main board, the secondary fixing clamp is used to drive the swinging part to move so that the support member swings to an inclined state, and the main board is provided with a transmission component for providing power for the movement of the secondary fixing clamp.

[0011] Furthermore, the transmission assembly includes: a secondary connecting rod and a swing plate. The secondary connecting rod is detachably connected to all the secondary fixing clamps and slidably connected to the main board. The swing plate is hinged to the lower part of the secondary connecting rod, contacts the main board and forms a lever, and contacts the base plate.

[0012] Furthermore, the support member is provided with a protruding ridge, and the protruding ridge, the support member and the swinging member are connected in sequence. The protruding ridge is provided with slag discharge holes that are evenly distributed at equal intervals on the side near the sub-plate.

[0013] Furthermore, the position of the swing portion away from the support portion and the position of the swing arm portion away from the support portion are both arc-shaped, which is used to improve the bending strength of the swing arm portion and the swing portion.

[0014] The beneficial effects of adopting the above technical solution are as follows:

[0015] 1. This invention utilizes the swing of the support member to lift one end of the lead frame upwards. On the one hand, this changes the contact position between the support member and the lead frame, and on the other hand, it makes the lead frame tilted, which facilitates the sliding off of metal debris from the surface of the lead frame, thereby ensuring the water washing effect on the lead frame and improving product reliability and service life.

[0016] 2. By relying on the groove of the support part, on the one hand, the contact area between the support part and the lead frame is reduced, which facilitates the falling off of metal debris on the lower side of the lead frame. On the other hand, when the support part swings, the groove on it can be used to push the lead frame to move to the limit position of the support part surface. This positioning of the lead frame makes it easier to load the lead frame after washing.

[0017] 3. By relying on the swing of the support part, the support part is in an inclined state. In this way, the support part and the inclined lead frame guide metal debris and other contaminants to slide down, making it easier for the cleaning fluid and water to carry the contaminants away from the lead frame and support part, thus improving cleaning efficiency.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] This embodiment discloses a water washing equipment for lead frame production, which reduces the blind spot in lead frame cleaning and improves the cleaning efficiency of lead frame.

[0032] See Figures 1 to 6 A water washing device for lead frame production includes: an ultrasonic cleaner 1, a main board 2, and a secondary board 3. The ultrasonic cleaner 1 is existing equipment and is not shown in the attached drawings. The main board 2 and the secondary board 3 are both located inside the ultrasonic cleaner 1, and the cleaning fluid or water inside the ultrasonic cleaner 1 covers the main board 2 and the secondary board 3. A top plate 4 is bolted to the upper part between the main board 2 and the secondary board 3. A handle is provided in the middle of the upper side of the top plate 4. A bottom plate 5 is slidably connected to the lower side of the main board 2 and the secondary board 3. The bottom plate 5 contacts the bottom inside the ultrasonic cleaner 1. The opposing sides of the main board 2 and the secondary board 3 are provided with an equal number of equally spaced grooves. Support members 6 and support members 7 are respectively embedded in the grooves of the main board 2 and the secondary board 3. The number of support members 6 and support members 7 is determined according to the height of the main board 2 and the secondary board 3, and is not further limited here. The support member 6 has a support portion 601 on its upper side, and the support member 7 has a support portion 701 and a swing arm portion 702. The cross-section of the support member 7 is an open triangle. The support member 7 is made of elastic metal, and the thickness of the left part of the support portion 701, the connection between the support portion 701 and the swing arm portion 702, and the connection between the swing arm portion 702 and the main fixing clamp 8 is less than the thickness of the rest of the support member 7. This allows the support member 7 to bend and deform when subjected to external force. The support portion 601 and the support portion 701 are used together to support the lead frame. Initially (this article defines the state when the main board 2 and the sub-board 3 are not placed in the ultrasonic cleaner 1 as the initial state, i.e., except for...) Figure 1 and Figure 2 (In addition to the states shown in the attached figures), the upper sides of the support 701 and the support 601 are coplanar. The swing arm 702 is fixedly connected to the main fixing clamp 8. There can be two main fixing clamps 8 on the same swing arm 702. The same applies to the main connecting rod 9. The main fixing clamps 8 in the same row are detachably connected to the main connecting rod 9 which is slidably connected to the sub-plate 3. The lower part of the main connecting rod 9 passes through the sub-plate 3 and is fixedly connected to the base plate 5. The base plate 5 is provided with a power mechanism for controlling the swing of the support 701 to change the support position of the support member 6 and the support member 7 on the lead frame.

[0033] The above setup enables the swinging of the support member 7 to lift one end of the lead frame upwards, thereby changing the contact position between the support member 6 and the support member 7 and the lead frame, and also tilting the lead frame to facilitate the sliding off of metal debris from the surface of the lead frame, thus ensuring the water washing effect on the lead frame and improving product reliability and service life.

[0034] It should be noted that, except for the ultrasonic cleaner 1, all parts in this application together constitute the lead frame's material box; this document uses the appendix... Figure 2 Let's take the perspective of [the person in question] as an example to illustrate.

[0035] See Figures 2 to 4 and Figure 7 The power mechanism includes two L-shaped components 10, a main liquid bladder 11, and two auxiliary liquid bladders 12. The two L-shaped components 10 are slidably connected within the base plate 5 and respectively contact the main plate 2 and the auxiliary plate 3, maintaining a constant distance between the main plate 2, the auxiliary plate 3, and the base plate 5. A rectangular recess is provided on the lower side of the base plate 5. The main liquid bladder 11 is fixed to the rectangular recess of the base plate 5 by adhesive bonding, and the horizontal projection area of ​​the main liquid bladder 11 is smaller than the horizontal projection area of ​​the rectangular recess on the lower side of the base plate 5. Initially, the lower side of the main liquid bladder 11 is located below the base plate 5; the auxiliary liquid bladder 12 is fixedly connected to the base plate 5 and to the adjacent L-shaped member 10. The auxiliary liquid bladder 12 is connected to the main liquid bladder 11 through a conduit. Both the main liquid bladder 11 and the auxiliary liquid bladder 12 contain damping fluid. The base plate 5 is equipped with a control component for regulating the flow rate of the damping fluid from the main liquid bladder 11 to the auxiliary liquid bladder 12. The elastic coefficient of the main liquid bladder 11 is greater than that of the auxiliary liquid bladder 12.

[0036] See Figure 3 and Figure 7The control components include a U-shaped component 13 and an adjusting bolt 14. The U-shaped component 13 is slidably connected to the base plate 5 and is used to compress the conduit between the main liquid bladder 11 and the auxiliary liquid bladder 12 to control the flow area of ​​the conduit between the main liquid bladder 11 and the auxiliary liquid bladder 12, thereby controlling the flow rate of the damping fluid. The adjusting bolt 14 is slidably connected to the U-shaped component 13 and threadedly connected to the base plate 5. The adjusting bolt 14 is used to control the relative position of the U-shaped component 13 and the base plate 5. Initially, the U-shaped component 13 completely isolates the conduit between the main liquid bladder 11 and the auxiliary liquid bladder 12. Both the main liquid bladder 11 and the auxiliary liquid bladder 12 are in a fully deployed but not inflated state (i.e., the main liquid bladder 11 and the auxiliary liquid bladder 12 have not undergone elastic deformation).

[0037] The water washing process for lead frames is as follows: First, the initial material box is placed on the unloading equipment of the lead frame processing production line. The unloading equipment sequentially places lead frames of the same specification to be cleaned into the material box, so that the left and right parts of the lead frame are respectively placed on the support part 601 and the support part 701. The adjusting bolt 14 is rotated using a tool to adjust the flow area of ​​the conduit between the main liquid bladder 11 and the auxiliary liquid bladder 12. This controls the timing of the start of action of the support 7, and thus controls the timing of the switching of the support position of the support part 601 and the support part 701 on the lead frame. That is, when the material box and the lead frame are placed... When the lead frame is placed in the ultrasonic cleaner 1, both the support part 601 and the support part 701 are in contact with the lower side of the lead frame to provide support for the lead frame. After the lead frame is cleaned in the ultrasonic cleaner 1 for a period of time (the period of time here refers to the time interval from when the lead frame is placed in the ultrasonic cleaner 1 until the support part 7 starts to move), the support part 7 starts to move and tilts the lead frame so that both the support part 601 and the support part 701 are in contact with the lower edge of the lead frame. In this way, the support positions of the support part 601 and the support part 701 on the lead frame are switched to improve the uniformity of water washing of the lead frame.

[0038] The material box containing the lead frame is placed into the ultrasonic cleaner 1. During this process, the main liquid bladder 11 first comes into contact with the ultrasonic cleaner 1. As the weight of the material box squeezes the main liquid bladder 11, the main liquid bladder 11 deforms and completely enters the rectangular recess of the base plate 5. In this state, the main liquid bladder 11 is affected by its own elasticity, and the damping fluid inside is slowly transported to the two auxiliary liquid bladders 12 through the conduit, causing the auxiliary liquid bladders 12 to expand and push the two L-shaped parts 10 to move away from each other.

[0039] After placing the material box into the ultrasonic cleaner 1, cleaning fluid is prepared in the ultrasonic cleaner 1 until it completely covers the top plate 4. At this time, the ultrasonic cleaner 1 is turned on to clean the lead frame. During the cleaning process, as the damping fluid in the main liquid bladder 11 is gradually injected into the auxiliary liquid bladder 12 through the conduit, the L-shaped part 10 moves slowly and the contact area with the main plate 2 and the auxiliary plate 3 gradually decreases. Finally, when the two L-shaped parts 10 completely lose contact with the main plate 2 and the auxiliary plate 3 respectively, the main plate 2, the auxiliary plate 3, the top plate 4 and the lead frame on it move downward relative to the bottom plate 5 under their own gravity. Since the main connecting rod 9 is fixed to the bottom plate 5, the main connecting rod 9 and the main fixing clamp 8 remain stationary during this process. The swing arm 702 swings counterclockwise around its connection with the adjacent main fixing clamp 8 (see attached diagram). Figure 2 The main view is a rotating perspective. The support 701 swings counterclockwise around its right edge, causing bending deformation at the connection between the swing arm 702 and the adjacent main fixing clamp 8, the left side of the support 701, and the connection between the support 701 and the swing arm 702. This causes the support 701 to change from a horizontal to an inclined state, and the horizontal height of each point on the support 701 is greater than the horizontal height of the support 601. This makes the entire lead frame tend to be inclined, resulting in an angle between the support 601 and the support 701 and the lead frame. That is, the lead frame changes from contacting the lower side to contacting the left and right edges. This changes the supported position of the lead frame, making the cleaning of the lead frame more complete, and the inclined lead frame makes it easier for metal debris to fall off.

[0040] After cleaning the lead frame with cleaning fluid and water in sequence, the ultrasonic cleaner 1 is stopped, and the material box is lifted out by the handle. During the lifting of the material box, the steps of moving the main board 2, sub-board 3, and top plate 4 relative to the bottom plate 5 are repeated in reverse to restore the shape of the support 7. After the main board 2, sub-board 3, and top plate 4 are reset relative to the bottom plate 5, the main board 2, sub-board 3, and top plate 4 drive the bottom plate 5 to move upward, so that the bottom plate 5 and the main liquid bladder 11 lose contact with the ultrasonic cleaner 1. Under the elastic action of the main liquid bladder 11 and the sub-liquid bladder 12, the damping fluid in the sub-liquid bladder 12 is delivered to the main liquid bladder 11 through the conduit, and the L-shaped part 10 gradually resets, thus completing a single cleaning process.

[0041] Example 2

[0042] This embodiment is a further optimization based on embodiment 1, providing a function for positioning the lead frame, which facilitates the loading of the lead frame after washing.

[0043] In existing technologies, the material box is used not only to carry the lead frame during the washing process, but also to transport the lead frame between different processes. Specifically, a loading mechanism is provided at the beginning of each process to transfer the lead frame from the material box to the equipment, and a unloading mechanism is provided at the end of each process to transfer the lead frame from the equipment back into the material box. Furthermore, the lead frame processing requires strict positioning accuracy. Therefore, existing technologies employ a dedicated active positioning mechanism to position the lead frame during the loading process. This application, however, actively positions the lead frame during the washing process, simplifying subsequent positioning operations in the equipment and eliminating the need for an active positioning mechanism in later processes, thus saving costs.

[0044] See Figures 4 to 6 The upper side of the support 701 is provided with evenly distributed grooves; the support 701 and the support 601 are coated with chromium nitride coating to improve surface hardness and smoothness.

[0045] The above configuration enables the following: relying on the groove of the support part 701, on the one hand, the contact area between the support part 701 and the lead frame is reduced, which facilitates the falling off of metal debris on the lower side of the lead frame; on the other hand, when the support part 701 swings, the groove on it can be used to push the lead frame to move, so that the lead frame moves to the limit position on the surface of the support part 601. In this way, the lead frame is positioned, which facilitates the loading of the lead frame after water washing.

[0046] Example 3

[0047] This embodiment is a further optimization based on embodiment 2.

[0048] See Figures 2 to 4 , Figure 8 and Figure 9 The support member 6 is provided with a swinging part 602, and the swinging part 602 is fixedly connected to a secondary fixing clamp 15. There can be two secondary fixing clamps 15 symmetrically distributed, and the same applies to the secondary connecting rod 16. The secondary fixing clamp 15 is limited and slidably connected to the main board 2. The secondary fixing clamp 15 is used to drive the swinging part 602 to move so that the support member 601 swings to an inclined state. The main board 2 is provided with a transmission component for providing power for the movement of the secondary fixing clamp 15.

[0049] See Figures 8 to 10 The transmission assembly includes a secondary connecting rod 16 and a swing plate 17. The secondary connecting rod 16 is detachably connected to all the secondary fixing clips 15 in the same column and slides vertically and vertically connected to the main plate 2. The swing plate 17 is hinged to the lower part of the secondary connecting rod 16. The swing plate 17 contacts the main plate 2 and forms a lever. The swing plate 17 contacts the base plate 5.

[0050] See Figure 8 and Figure 9The support member 6 has a protruding ridge 603 on its upper left side. The protruding ridge 603, the support member 601, and the swinging member 602 are connected in sequence. The protruding ridge 603 is used to limit the limit position of the lead frame to move to the left on the support member 601. The support member 6 is made of elastic metal, and the thickness of the connection between the support member 601 and the protruding ridge 603, the connection between the support member 601 and the swinging member 602, and the connection between the swinging member 602 and the adjacent secondary fixing clip 15 is smaller than the thickness of the rest of the support member 6. The thickness of the support member 6 allows it to bend and deform at the connection between the support part 601 and the protruding part 603, the connection between the support part 601 and the swing part 602, and the connection between the swing part 602 and the adjacent auxiliary fixing clamp 15 when subjected to external force. The right side of the protruding part 603 is provided with equidistant and evenly distributed slag discharge holes 604. The lower left part of the swing part 602 and the lower part of the swing arm 702 are both arc-shaped to improve the bending strength of the swing arm 702 and the swing part 602.

[0051] The above configuration enables the support part 601 to be tilted by swinging, so that metal debris and other contaminants are guided to slide down through the support part 601 and the tilted lead frame, making it easier for the cleaning fluid and water to carry the contaminants away from the lead frame and the material box, thereby improving cleaning efficiency.

[0052] During the downward movement of the main board 2, sub-board 3, and top plate 4 relative to the bottom plate 5, the main board 2 and bottom plate 5 jointly press the swing plate 17, causing the swing plate 17 to swing and drive the sub-connecting rod 16 to move downward relative to the main board 2. The sub-connecting rod 16 drives the lower part of all swing parts 602 to move downward through the sub-fixing clamp 15. The connection between the swing part 602 and the adjacent sub-fixing clamp 15, the connection between the swing part 602 and the support part 601, and the connection between the support part 601 and the protruding part 603 all undergo bending deformation, which increases the angle between the swing part 602 and the support part 601 and causes the support part 601 to swing clockwise until the swing plate 17 finally swings to a horizontal state. At this time, the main board 2 contacts the bottom plate 5 and stops moving downward. At this time, the support part 601 changes from a horizontal state to an inclined state, which facilitates the sliding of metal debris on the upper side of the support part 601.

[0053] During the process of washing and lifting the material box by the handle, the main board 2 moves upward relative to the base plate 5, increasing the distance between them. The support 6 gradually recovers its shape under its own elastic force. The process of moving the secondary fixing clamp 15 downward relative to the main board 2 is repeated in reverse, so that the support 6, the secondary fixing clamp 15, the secondary connecting rod 16 and the swing plate 17 are all reset relative to the main board 2.

[0054] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
