Description

Technical Field

[0001] This invention relates to the field of semiconductor packaging equipment technology, and in particular to an epoxy resin lifting and feeding device. Background Technology

[0002] In semiconductor chip packaging, cylindrical epoxy resin is required, thus necessitating a feeding device to feed the epoxy resin. As described in patent CN116666286A, in order to fit with the sheet material, the epoxy resin feeding mechanism is usually located at a high position. A feeding machine is needed to push the epoxy resin layer by layer upwards onto the feeding mechanism. However, the working range of the feeding machine is limited, that is, the feeding height of the feeding machine is limited. Therefore, the feeding port of the feeding machine is set at a high position, which causes inconvenience for workers to feed the material. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide an epoxy resin lifting and feeding device that uses a lifting mechanism to lift the arranged epoxy resin upwards, thereby reducing the feed inlet for manual feeding and facilitating manual feeding.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: an epoxy resin lifting and feeding device, comprising:

[0005] The transfer mechanism includes a first cylinder that can reciprocate between a feeding position and a transfer position along a first direction. The first cylinder has a plurality of first cavities that can store the epoxy resin. The first cavities of the first cylinder at the feeding position are all in a closed state, and the first cavities of the first cylinder at the transfer position are in an open state. The feeding mechanism includes a discharge channel located on a second side of the first material cylinder body. The height of the discharge channel is higher than the height of the first material cylinder. A first pushing component is provided on one side of the discharge channel. The first pushing component is used to push the epoxy resin in the discharge channel into the first cavity of the first material cylinder at the feeding position one by one. The lifting mechanism includes a second cylinder that moves up and down to switch between a lifting position and a lowering position. The second cylinder has a second cavity that corresponds one-to-one with the first cavity. The lowering position is located directly below the transition position, and the second cavity of the second cylinder in the lowering position is in a closed state.

[0006] The beneficial effects of this invention are as follows: the lifting mechanism allows the feeding mechanism to be positioned at a lower level, facilitating manual feeding. The epoxy resin is lifted to the lifting position by the lifting mechanism for subsequent processing. To cooperate with the lifting mechanism, a transfer mechanism is provided to transfer the epoxy resin between the feeding mechanism and the lifting mechanism. The epoxy resin is arranged at the transfer mechanism and can connect with the lifting mechanism at the transfer position. The epoxy resin can be transferred from the first material cylinder to the second material cylinder solely by gravity.

[0007] Furthermore, both the first and second barrels include a barrel body and a baffle that can move along the barrel body in a first direction. Multiple first or second cavities are formed on the barrel body and distributed along the first direction. The baffle has clearance holes corresponding one-to-one with the first or second cavities, and these clearance holes can be aligned with or staggered with the first or second cavities. The first or second cavity is opened and closed by sliding the baffle.

[0008] Furthermore, a first push plate is provided at the feeding position, and the first push plate abuts against one end of the baffle of the first material cylinder at the feeding position so that the clearance hole on the baffle intersects with the first cavity; a second push plate is provided on the second material cylinder, and the second push plate abuts against the other end of the baffle of the first material cylinder at the transition position so that the clearance hole on the baffle aligns with the first cavity. The opening and closing of the first cavity does not require a driving component to move the baffle, but can be achieved by the movement of the first material cylinder and the stationary first push plate and the second push plate provided on the second material cylinder, which is simple in structure and low in cost.

[0009] Furthermore, a pusher assembly is also provided at the descending position. The pusher assembly includes a third pusher that can reciprocate along a first direction. The third pusher can push the baffle of the second barrel at the descending position to move so that the clearance hole on the baffle and the second cavity are intersected. Because the second barrel can only move up and down, the pusher assembly is provided to push the baffle of the second barrel at the descending position, so that the second chamber of the second barrel is in a closed state to receive the epoxy resin falling from the first barrel.

[0010] Furthermore, a connecting block is fixed above the first material cylinder on the discharge channel. The connecting block has a guide channel that communicates with the first cavity, through which the epoxy resin on the discharge channel falls into the first cavity. Because the discharge channel and the first cavity are intersected, a connecting block with a guide channel is provided to ensure that the epoxy resin on the discharge channel can enter the first cavity.

[0011] Furthermore, the guide channel includes an L-shaped horizontal section and a vertical section. When the vertical section is aligned with the first cavity, the first pusher assembly pushes out the horizontally placed epoxy resin. The epoxy resin flips at the connection between the horizontal and vertical sections and falls vertically into the first cavity. The vertical and horizontal sections cooperate with each other, utilizing the epoxy resin's own gravity to partially suspend the epoxy resin, thus achieving a 90-degree flip.

[0012] Furthermore, the transfer mechanism also includes a lateral movement drive, which is connected to a connecting plate with one end suspended and located on one side of the lateral movement drive in a second direction. The first material cylinder is fixed to the suspended end of the connecting plate. The first material cylinder is positioned at the suspended end to ensure that the lateral movement drive does not obstruct the alignment of the first and second material cylinders in the vertical direction.

[0013] Furthermore, the lateral movement drive is disposed on the substrate, and the substrate has a notch formed at the transition position, allowing the first barrel to move directly above the notch. The substrate supports the lateral movement drive, and the notch provides clearance for the docking of the first and second barrels.

[0014] Furthermore, the feeding mechanism also includes a pusher, a conveyor line, and a second pusher assembly. The pusher is used to push the epoxy resin in rows onto the conveyor line. The conveyor line conveys the epoxy resin along a second direction and is connected to the discharge channel. The second pusher assembly is used to push the epoxy resin on the conveyor line one by one onto the discharge channel.

[0015] Furthermore, the discharge channel is inclined, with its high end connected to the conveyor line, and the loading position located at the low end of the discharge channel. The epoxy resin within the discharge channel can slide within the channel towards the area aligned with the loading position using its own gravity. Attached Figure Description

Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] In the diagrams below, X is the first direction, Y is the second direction, and Z is the vertical direction.

[0022] The present invention provides an epoxy resin lifting and feeding device for feeding epoxy resin.

[0023] See appendix Figure 1 and attached Figure 2As shown, the epoxy resin lifting and feeding device includes a feeding mechanism 2, a transfer mechanism 1, and a lifting mechanism 3. The feeding mechanism 2 is used to feed epoxy resin one by one. The transfer mechanism 1 is connected to the feeding mechanism 2 and is used for arranging epoxy resin. The lifting mechanism 3 is connected to the transfer mechanism 1 and is used for lifting the arranged epoxy resin.

[0024] See appendix Figure 3 As shown, the transfer mechanism 1 includes a first material cylinder 11 that can reciprocate between a loading position and a transfer position along a first direction. The first material cylinder 11 has multiple first cavities 111 for storing epoxy resin. The first cavities 111 of the first material cylinder 11 at the loading position are all in a closed state, while the first cavities 111 of the first material cylinder 11 at the transfer position are in an open state. The closed state here does not mean that the first cavity 111 is completely closed; as long as the epoxy resin in the first cavity 111 cannot slide out, the first cavity 111 is considered closed. In the attached figure, the first material cylinder 11 is located at the loading position, where it is connected to the loading mechanism 2, which places epoxy resin into the first cavity 111. Only one epoxy resin can be placed in each first cavity 111. The first material cylinder 11 achieves the separation and arrangement of epoxy resin to meet subsequent processing requirements.

[0025] See appendix Figure 3 and attached Figure 5 As shown, the feeding mechanism 2 includes a discharge channel 21 located on one side of the first material cylinder 11 body in a second direction. The height of the discharge channel 21 is higher than the height of the first material cylinder 11. A first pushing component 22 is provided on one side of the discharge channel 21. The first pushing component 22 is used to push the epoxy resin in the discharge channel 21 one by one into the first cavity 111 of the first material cylinder 11 at the feeding position. Since the discharge channel 21 is higher than the first material cylinder 11, when the first pushing component 22 pushes the material, the epoxy resin can fall into the first material cylinder 11 by its own gravity.

[0026] The lifting mechanism 3 includes a second material cylinder 31 that moves up and down to switch between a lifting position and a lowering position. The second material cylinder 31 has a second cavity 3111 that corresponds one-to-one with the first cavity 111. The lowering position is located directly below the transition position, and the second cavity 3111 of the second material cylinder 31 in the lowering position is in a closed state. See Appendix. Figure 6 As shown, at this time, the first cavity 111 of the first material cylinder 11 is in the open state. Because the second material cylinder 31 is located below the first material cylinder 11, the epoxy resin in the first material cylinder 11 can fall into the second material cylinder 31 under its own gravity.

[0027] In this embodiment, the feeding device includes a lifting mechanism 3, which allows the feeding mechanism 2 to be positioned at a lower level for easier manual feeding. The epoxy resin is lifted to the lifting position via the lifting mechanism 3 for subsequent processing. To facilitate the lifting mechanism 3, a transfer mechanism 1 is provided to transfer the epoxy resin between the feeding mechanism 2 and the lifting mechanism 3. The epoxy resin is arranged at the transfer mechanism 1 and can connect with the lifting mechanism 3 at the transfer position. The epoxy resin can be transferred from the first material cylinder 11 to the second material cylinder 31 using only its own weight.

[0028] The first feed cylinder 11 and the second feed cylinder 31 have basically the same structure; see appendix. Figure 6 and attached Figure 7 As shown, both the first barrel 11 and the second barrel 31 include a barrel body 311 and a baffle 312 that can move along the barrel body 311 in a first direction. The first cavity 111 or the second cavity 3111 is opened on the barrel body 311 and multiple cavities are distributed along the first direction. The baffle 312 is provided with a clearance hole 3121 that corresponds one-to-one with the first cavity 111 or the second cavity 3111. The clearance hole 3121 can be aligned with or staggered with the first cavity 111 or the second cavity 3111. When the clearance hole 3121 is aligned with the first cavity 111 or the second cavity 3111, the first cavity 111 or the second cavity 3111 is in the open state, and the epoxy resin can slide out from the lower opening of the first cavity 111 or the second cavity 3111; when the clearance hole 3121 is staggered with the first cavity 111 or the second cavity 3111, the first cavity 111 or the second cavity 3111 is in the closed state, and the epoxy resin cannot slide out from the lower opening of the first cavity 111 or the second cavity 3111.

[0029] The first cavity 111 and the second cavity 3111 penetrate vertically through the barrel body 311 of the first barrel 11 and the barrel body 311 of the second barrel 31, respectively. Both the first cavity 111 and the second cavity 3111 have an upper opening and a lower opening. Epoxy resin enters the first cavity 111 or the second cavity 3111 through the upper opening and exits through the lower opening. The diameters of the first cavity 111 and the second cavity 3111 are slightly larger than the diameter of the epoxy resin to ensure that the epoxy resin can enter and slide out. The diameter of the clearance hole 3121 is the same as the diameter of the first cavity 111.

[0030] The length of the baffle 312 in the first direction is greater than the length of the barrel body 311 in the first direction. At this time, the baffle 312 will inevitably extend out of the barrel body 311 in the first direction. The baffle 312 extending out of the barrel body 311 can be pushed from the outside of the barrel body 311 to push the baffle 312 to slide relative to the barrel body 311.

[0031] In one embodiment, see Appendix Figure 2and attached Figure 5 As shown, a first pusher plate 12 is provided at the feeding position. The first pusher plate 12 and one end of the baffle 312 of the first material cylinder 11 at the feeding position abut against each other so that the clearance hole 3121 on the baffle 312 and the first cavity 111 are staggered. The first pusher plate 12 remains stationary at the end of the feeding position away from the transition position. When the first material cylinder 11 moves to the feeding position, the first pusher pushes the baffle 312 toward the docking position. At this time, the clearance hole 3121 and the first cavity 111 are staggered, and the first cavity 111 is closed. At the same time, the first cavity 111 closest to the transition position on the first material cylinder 11 rotates with the first pusher assembly 22. The first pusher assembly 22 pushes a piece of epoxy resin into the first cavity 111 closest to the transition position. During the process of the first material cylinder 11 moving toward the transfer position, the baffle 312 is not subjected to external force and remains in the state of closing the first cavity 111. The first cavity 111 is aligned with the first feeding assembly in sequence to complete the feeding of all the first cavities 111.

[0032] See appendix Figure 6 and attached Figure 7 As shown, a second push plate 313 is provided on the second material cylinder 31. The second push plate 313 abuts against the other end of the baffle 312 of the first material cylinder 11 at the transition position so that the clearance hole 3121 on the baffle 312 is aligned with the first cavity 111. The second push plate is fixed on the material cylinder body 311 of the second material cylinder 31 and can extend upward to the height of the docking position. Before the first material cylinder 11 moves to the docking position, the second material cylinder 31 has already descended to the lowered position. At this time, when the first material cylinder 11 moves to the docking position, the fixed second push plate 313 pushes the other end of the baffle 312 to slide the baffle 312 relative to the material cylinder body 311 of the first material cylinder 11 until the first material cylinder 11 and the second material cylinder 31 are aligned vertically. At this time, the baffle 312 just moves to the position of opening the first cavity 111, and the epoxy resin in the first cavity 111 falls into the second cavity 3111 under the action of gravity.

[0033] The first cylinder 11 and the second cylinder 31 also include a limiting plate 314 fixed on the cylinder body 311. The limiting plate 314 can abut against the end of the baffle 312 to limit the movement distance of the baffle 312. When the baffle 312 and the limiting plate 314 abut against each other, the first cavity 111 or the second cavity 3111 is in the open state.

[0034] In this embodiment, the opening and closing of the first cavity 111 does not require a driving component to move the baffle 312. It can be achieved by moving the first material cylinder 11 and fixing the first push plate 12 and the second push plate 313 set on the second material cylinder 31. The structure is simple and the cost is low.

[0035] See appendix Figure 3As shown, the transfer mechanism 1 also includes a transverse drive 13, which is connected to a connecting plate with one end suspended and located on one side of the transverse drive 13 in a second direction. A first material cylinder 11 is fixed to the suspended end of the connecting plate. The first material cylinder 11 is positioned at the suspended end to ensure that the transverse drive 13 does not obstruct the alignment of the first material cylinder 11 and the second material cylinder 31 in the vertical direction. The transverse drive 13 is a linear drive; for example, the transverse drive 13 includes a closed-loop, rotatable conveyor belt, and the connecting plate is fixed to the straight section of the conveying section.

[0036] A transverse drive 13 is disposed on a substrate 14. A notch 141 is formed on the substrate 14 at the transition position, allowing the first barrel 11 to move directly above the notch 141. The substrate 14 supports the transverse drive 13, and the notch 141 facilitates the docking of the first barrel 11 and the second barrel 31. A guide rail is provided on the substrate 14, along which a connecting plate slides. The guide rail guides the sliding of the connecting plate and supports the weight of the first barrel 11. A pusher assembly 32 is disposed on the substrate 14 near the notch 141, and the pusher drive is fixed to the substrate 14.

[0037] In one embodiment, a pusher assembly 32 is also provided at the descending position. The pusher assembly 32 includes a third pusher that can reciprocate along a first direction. The third pusher can push the baffle 312 of the second material cylinder 31 at the descending position to move so that the clearance hole 3121 on the baffle 312 and the second cavity 3111 are intersected. Because the second material cylinder 31 can only move vertically, but the baffle 312 must move along the first direction of the horizontal plane to achieve the switching of opening and closing of the second cavity 3111, and because the second cavity 3111 needs to be opened after the second material cylinder 31 reaches the lifting position in order to let the epoxy resin fall onto the conveying mechanism 4, the second cavity 3111 is always in the open state during the descent of the second material cylinder 31 from the lifting position to the descending position. In order to enable the second barrel 31 at the descending position to carry epoxy resin, a third push plate is provided at the descending position. The active movement of the third push plate is used to push the baffle 312 of the second barrel 31 to move to the intersection of the second cavity 3111 and the clearance hole 3121.

[0038] The pusher assembly 32 also includes a pusher drive, which drives the third pusher to move. Before the first material cylinder 11 enters the transition position, the third pusher first pushes the baffle 312 of the second material cylinder 31 at the descending position to close the second cavity 3111.

[0039] In this embodiment, epoxy resin transfer is achieved through the cooperation of the first material cylinder 11 and the second material cylinder 31. While the first material cylinder 11 is feeding the material, the second material cylinder 31 can dock with the conveying mechanism 4 to discharge the material, thereby improving the feeding efficiency of the feeding device.

[0040] The lifting mechanism 3 also includes a lifting drive component 33, which is fixedly connected to the second material cylinder 31 and is used to drive the second material cylinder 31 to move vertically. In this embodiment, the lifting drive component 33 and the lateral drive component 13 have similar structures and also use a transmission belt to achieve linear movement.

[0041] See appendix Figure 3 and attached Figure 4 As shown, a transition block 23 is also fixed on the discharge channel 21, located above the first material cylinder 11. The transition block 23 has a guide channel 231 that connects the discharge channel 21 and the first cavity 111. The epoxy resin on the discharge channel 21 falls into the first cavity 111 through the guide channel 231. The transition block 23 is used to guide the epoxy resin. Because the discharge channel 21 and the first cavity 111 are intersected, the transition block 23 with the guide channel 231 is used to connect the two, ensuring that the epoxy resin on the discharge channel 21 can enter the first cavity 111.

[0042] The epoxy resin in the discharge channel 21 is horizontal, but the epoxy resin in the first cavity 111 is vertical. Therefore, the guide channel 231 includes an L-shaped horizontal section and a vertical section. When the vertical section is aligned with the first cavity 111, the first pusher assembly 22 pushes out the horizontally placed epoxy resin. The epoxy resin flips at the junction of the horizontal and vertical sections and falls vertically into the first cavity 111. The vertical and horizontal sections cooperate with each other, using the gravity of the epoxy resin itself to partially suspend the epoxy resin, thereby achieving a 90-degree flip of the epoxy resin.

[0043] The feeding mechanism 2 also includes a pusher 24, a conveyor line 25, and a second pushing assembly 26. The pusher 24 is used to push the epoxy resin in rows onto the conveyor line 25. The pusher 24 is existing technology and will not be described in detail here. The conveyor line 25 conveys epoxy resin along the second direction and is connected to the discharge channel 21. The second pushing assembly 26 is used to push the epoxy resin on the conveyor line 25 one by one onto the discharge channel 21.

[0044] In one embodiment, see Appendix Figure 5 As shown, the discharge channel 21 is inclined, and its high end is connected to the conveyor line 25, while the loading position is located at the low end of the discharge channel 21. The epoxy resin in the discharge channel 21 can slide within the discharge channel 21 towards the area aligned with the loading position using its own gravity.

[0045] The first pusher assembly 22 and the second pusher assembly 26 have the same structure, both including a pusher drive and a pusher rod connected to the pusher drive. The pusher drive drives the pusher rod to extend to push the epoxy resin.

[0046] See appendix Figure 1As shown, the feeding device also includes a conveying mechanism 4, which includes a three-axis moving platform and a third material cylinder. The third material cylinder can dock with the second material cylinder 31 at the lifting position and convey the epoxy resin inside the second material cylinder 31. The third material cylinder and the second material cylinder 31 have the same structure. The third material cylinder can be moved to directly below the lifting position by the three-axis moving platform. At this time, the second push plate 313 on the third material cylinder can push the baffle 312 of the second material cylinder 31 to the position of opening the second cavity 3111. The epoxy resin inside the second cavity 3111 falls into the third material cylinder under the action of gravity. The conveying mechanism 4 conveys the third material cylinder to dock with the semiconductor wafer.

[0047] In one embodiment, an epoxy resin lifting and feeding method employs the above-mentioned feeding device, and the method includes: The epoxy resin is placed into the low-positioned barrel, and the pusher 24 pushes the epoxy resin in rows onto the conveyor line 25. The conveyor line 25 conveys the epoxy resin along the second direction and is connected to the discharge channel 21. The second pusher assembly 26 is used to push the epoxy resin on the conveyor line 25 one by one onto the discharge channel 21.

[0048] The first material cylinder 11 moves to the feeding position, and the first pusher pusher baffle 312 moves toward the docking position. At this time, the clearance hole 3121 and the first cavity 111 are intersected, and the first cavity 111 is closed. At the same time, the first cavity 111 closest to the transfer position on the first material cylinder 11 is aligned with the first pusher assembly 22, and the first pusher assembly 22 pushes an epoxy resin into the first cavity 111 closest to the transfer position.

[0049] Before the first material cylinder 11 moves toward the transfer position, the second material cylinder 31 moves down to the lower position, and the push plate assembly 32 pushes the baffle 312 of the second material cylinder 31 at the lower position to close the second cavity 3111.

[0050] During the process of the first material cylinder 11 moving to the docking position, the second push plate 313 of the second material cylinder 31 pushes the other end of the baffle 312 of the first material cylinder 11 to slide relative to the material cylinder body 311 of the first material cylinder 11 until the first material cylinder 11 and the second material cylinder 31 are aligned vertically. At this time, the baffle 312 just moves to the position of opening the first cavity 111, and the epoxy resin in the first cavity 111 falls into the second cavity 3111 under the action of gravity.

[0051] The lifting drive 33 drives the second material cylinder 31 to move up to the lifting position, and the conveying mechanism 4 conveys the epoxy resin in the second material cylinder 31.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
