Die ring storage device and die bonder

Abstract

This utility model relates to the field of die bonding equipment technology, providing a crystal ring storage device and a die bonding machine. The crystal ring storage device includes a main support and a support assembly. The support assembly is used to place the crystal rings. Each support assembly includes a first support portion and a second support portion, which are spaced apart from each other along a second direction to form a clearance space for the crystal ring picking mechanism. The first direction and the second direction are arranged at an angle. When the crystal ring picking mechanism picks up the crystal ring from the support assembly, the working end of the crystal ring picking mechanism can extend under the crystal ring, and then pass through the clearance space along the first direction to lift the crystal ring a certain distance, so that the crystal ring is separated from both the first and second support portions. Then the crystal ring is taken out from the support assembly, thereby avoiding the phenomenon of dust generation caused by friction between the crystal ring and the support assembly during the crystal ring picking process, and improving the working environment of the die bonding equipment.

Description

Technical Field

[0001] This utility model belongs to the technical field of crystal bonding equipment, and in particular relates to a crystal ring storage device and a crystal bonding machine. Background Technology

[0002] Die bonders are key pieces of equipment used in semiconductor packaging and LED manufacturing. Their main function is to precisely separate chips from die rings and fix them onto substrates (such as PCBs, brackets, etc.), achieving a stable bond through adhesives (such as silver paste) or eutectic bonding processes. Die bonders are equipped with die ring storage devices that store multiple die rings for use with die ring gripping devices to feed the chips. However, in existing die ring storage devices, during the chip ring handling process, friction between the die rings and the support components on the storage device generates dust, which can contaminate the working environment of the die bonder. Utility Model Content

[0003] The purpose of this invention is to provide a crystal ring storage device and a crystal bonding machine, which aims to solve the technical problem that dust is easily generated by friction when the crystal ring is picked up in the prior art.

[0004] This invention is implemented as follows: Firstly, a crystal ring storage device is provided. The crystal ring storage device includes a main support and a support assembly. The support assembly is used to place the crystal ring. There are multiple support assemblies, which are sequentially and spaced apart on the main support along a first direction. Each support assembly includes a first support portion and a second support portion. The first support portion and the second support portion are spaced apart from each other along a second direction to form a clearance space for avoiding the crystal ring picking mechanism. The first direction and the second direction are arranged at an angle.

[0005] In an optional embodiment, the support component is provided with a positioning structure, and the positioning mechanism is used to position the crystal ring on the support component.

[0006] In an optional embodiment, the positioning structure includes two positioning protrusions, which are spaced apart along the second direction, and the two positioning protrusions respectively protrude from the surfaces of the first support portion and the second support portion that contact the crystal ring.

[0007] In an optional embodiment, the positioning protrusion includes a positioning pin, and both the first support portion and the second support portion have pin mounting holes on their surfaces that contact the crystal ring, with at least a portion of the positioning pin inserted into the pin mounting hole.

[0008] In an alternative embodiment, the crystal ring storage device further includes a pusher mechanism for pushing the crystal ring toward the positioning structure.

[0009] In an optional embodiment, the pushing mechanism includes a pushing component and a driving unit. The pushing component is located on the side of the support assembly and has a degree of freedom of movement relative to the support assembly. The driving unit is used to drive the pushing component to move.

[0010] In an optional embodiment, the pusher is provided with an elastic buffer layer, which is disposed on the side of the pusher facing the support assembly.

[0011] In one optional embodiment, the main support includes a base plate, a top plate, a first support column, and a second support column. The base plate and the top plate are spaced apart from each other along the first direction. The first support column and the second support column are both connected between the base plate and the top plate. A plurality of first support portions are spaced apart and connected to the first support column, and a plurality of second support portions are spaced apart and connected to the second support column.

[0012] In an optional embodiment, the first support column passes through the first support portion, and a first spacer sleeve is provided between each two adjacent first support portions to separate them. The first spacer sleeve is fitted onto the outside of the first support column. The second support column passes through the second support portion, and a second spacer sleeve is provided between each two adjacent second support portions to separate them. The second spacer sleeve is fitted onto the outside of the second support column.

[0013] On the other hand, a die bonder is provided, including the crystal ring storage device described in any of the above claims.

[0014] The first aspect of this invention provides the following technical advantage: By arranging multiple support components on the main support, and these components being spaced apart sequentially along a first direction, multiple crystal rings can be stored by placing a crystal ring on each support component. Each support component includes a first support portion and a second support portion, which are spaced apart along a second direction to form a clearance space for the working end of the crystal ring picking mechanism. Compared to existing crystal ring storage devices, when the crystal ring picking mechanism retrieves a crystal ring from the support component, its working end can extend under the crystal ring, pass through the clearance space along the first direction, and lift the crystal ring a certain distance, detaching it from both the first and second support portions. The crystal ring is then removed from the support component, thus preventing dust generation due to friction between the crystal ring and the support component during retrieval, and improving the working environment during crystal bonding equipment production.

[0015] It is understandable that the beneficial effects of the second aspect mentioned above can be found in the relevant descriptions in the first aspect mentioned above, and will not be repeated here. Attached Figure Description

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

[0030] Please refer to Figure 1 and Figure 2 As shown in the present invention, a crystal ring storage device is provided, including a main support 1 and a support component 2. The support component 2 is used to place the crystal ring. There are multiple support components 2, which are arranged sequentially and spaced apart on the main support 1 along a first direction. Each support component 2 includes a first support part 21 and a second support part 22. The first support part 21 and the second support part 22 are arranged spaced apart from each other along a second direction to form a clearance space 23 for avoiding the crystal ring picking mechanism. The first direction and the second direction are arranged at an angle.

[0031] Specifically, the main support 1 refers to a support assembly 2 with a certain height, which is typically composed of multiple parts. The first support part 21 and the second support part 22 are both components with a certain volume; to reduce overall weight, both the first support part 21 and the second support part 22 can be plate-shaped. The first support part 21 and the second support part 22 are spaced apart from each other in a second direction to form the aforementioned support assembly 2. During normal operation of the crystal ring storage device, the first direction is generally vertical. The angle between the second direction and the first direction is generally a right angle; that is, when the first direction is vertical, the second direction can be any direction in the horizontal plane.

[0032] The crystal ring picking mechanism is a component that removes and transports the crystal ring from the support assembly 2. The working end of the crystal ring picking mechanism has the freedom to move in both the horizontal and vertical directions. The working end of the crystal ring picking mechanism can contact the crystal ring by clamping, lifting from below, or adsorbing. The specific structure of the crystal ring picking mechanism is a well-known technical means in the art and will not be described in detail here.

[0033] The crystal ring storage device provided in this embodiment of the invention stores multiple crystal rings by setting multiple support components 2 on the main support 1 and arranging the multiple support components 2 sequentially at intervals along a first direction, and by placing a crystal ring on each support component 2. Each support component 2 includes a first support part 21 and a second support part 22, which are spaced apart from each other along a second direction to form a clearance space 23 for avoiding the working end of the crystal ring picking mechanism. Compared with existing crystal ring storage devices, when the crystal ring picking mechanism picks up a crystal ring from the support component 2, the working end of the crystal ring picking mechanism can extend under the crystal ring, then pass through the clearance space 23 along the first direction and lift the crystal ring a certain distance, causing the crystal ring to detach from both the first support part 21 and the second support part 22. The crystal ring is then removed from the support component 2, thus avoiding the phenomenon of dust generation due to friction between the crystal ring and the support component 2 during the crystal ring picking process, and improving the working environment during crystal bonding equipment production.

[0034] In one embodiment, see Figure 1 The support component 2 is provided with a positioning structure 3, which is used to position the crystal ring on the support component 2. Specifically, the positioning structure 3 refers to a structure or component that can position an object. The positioning structure 3 can be a protrusion, groove, or hole structure, etc. The positioning structure 3 can also be a positioning component installed on the support component 2, such as a positioning block, positioning baffle, or positioning pin. In this embodiment, by providing a positioning structure 3 on the support component 2, the crystal ring can be positioned when it is placed on the support component 2, preventing the crystal ring from being skewed after being fed, and making the crystal ring placement more accurate.

[0035] In one embodiment, see Figure 2 The positioning structure 3 includes two positioning protrusions 31, which are spaced apart along a second direction and protrude from the surfaces of the first support portion 21 and the second support portion 22 that contact the crystal ring. Specifically, the positioning protrusion 31 refers to a protrusion with a certain height. The positioning protrusion 31 can be integrally formed with the first support portion 21 or the second support portion 22, or it can be an additional component that is fixed to the first support portion 21 or the second support portion 22 by welding, snap-fitting, or fastener connection. In this embodiment, since the outer periphery of the crystal ring is usually circular, the positioning structure 3 uses two positioning protrusions 31 spaced apart along the second direction, and the two positioning protrusions 31 are respectively disposed on the surfaces of the first support portion 21 and the second support portion 22 that contact the crystal ring. This simplifies the overall structure of the positioning structure 3 and reduces the manufacturing cost of the device while ensuring stable positioning.

[0036] In one embodiment, see Figure 3 The positioning protrusion 31 includes a positioning pin 311, and both the first support portion 21 and the second support portion 22 have pin mounting holes on their surfaces that contact the crystal ring. At least a portion of the positioning pin 311 is inserted into the pin mounting hole. Specifically, the positioning pin 311 refers to a columnar structure with a certain length. The pin mounting hole refers to a hole structure with a certain depth. In this embodiment, by providing pin mounting holes on the surfaces of the first support portion 21 and the second support portion 22 that contact the crystal ring, and then inserting at least a portion of the positioning pin 311 into the pin mounting hole, the other portion of the positioning pin 311 can protrude from the surface of the first support portion 21 or the second support portion 22 to form the positioning protrusion 31. When the crystal ring is placed, it can abut against the side of the crystal ring, which, while limiting the crystal ring, makes the installation of the positioning protrusion 31 more convenient.

[0037] In an optional embodiment, please refer to Figure 3 The positioning pin 311 includes a positioning part, an insertion part, and a guide part. The insertion part and the guide part are located at opposite ends of the positioning part. The positioning part is cylindrical, ensuring its outer circumference remains unchanged regardless of rotation. The shape of the insertion part matches the size of the pin mounting hole. The guide part is conical, with its bottom connected to the positioning part. In this embodiment, by placing the insertion part and the guide part at opposite ends of the positioning part, the insertion part is inserted into the pin mounting hole and tightened during installation, thus installing the positioning pin 311. The positioning part then positions the crystal ring, making its placement more accurate. Simultaneously, a conical guide part is provided at the other end of the positioning part to guide the crystal ring, facilitating contact and separation between the crystal ring and the positioning part.

[0038] In one embodiment, see Figure 1 The crystal ring storage device also includes a pushing mechanism 4, which is used to push the crystal ring towards the positioning structure 3. Specifically, the pushing mechanism 4 refers to a component or assembly that can push an object in a straight line. In this embodiment, by providing the pushing mechanism 4, when the crystal ring is placed on the support assembly 2, the pushing mechanism 4 can push the crystal ring towards the positioning structure 3 until the crystal ring abuts against the positioning pin 311 to complete the positioning of the crystal ring.

[0039] In one embodiment, see Figure 4The pushing mechanism includes a pushing component 41 and a driving unit 42. The pushing component 41 is located on the side of the support assembly 2 and has a degree of freedom of movement relative to the support assembly 2. The driving unit 42 is used to drive the pushing component 41 to move. Specifically, the pushing component 41 refers to a component with a certain length, which can be rod-shaped or column-shaped, etc. The driving unit 42 refers to a component that can drive an object to move in a straight line, which can be a cylinder, hydraulic cylinder, or electric push rod, etc. In this embodiment, by installing the pushing component 41 on the driving end of the driving unit 42 and setting the pushing component 41 along the first direction on the side of the support assembly 2, after multiple crystal rings are placed on the support assembly 2, the driving unit 42 drives the pushing component 41 to push multiple crystal rings towards the positioning structure 3, so that the crystal rings abut against the positioning pin 311 to achieve crystal ring positioning. At the same time, the driving unit 42 drives the pushing component 41 to push multiple crystal rings simultaneously, which also improves the efficiency of crystal ring positioning.

[0040] In one embodiment, see Figure 4 An elastic buffer layer is provided on the pusher component 41, located on the side of the pusher component 41 facing the support component 2. Specifically, the elastic buffer layer refers to an elastic component, and the material of the elastic buffer layer can be rubber, silicone, or polyurethane, etc. The elastic buffer layer is usually a plate-like structure and is connected to the pusher component 41 by means of adhesion, fastener connection, or snap-fit. In this embodiment, by providing an elastic buffer layer on the side of the pusher component 41 facing the support component 2, damage to the crystal ring can be avoided by the pusher component 41 when it comes into contact with the crystal ring.

[0041] In one embodiment, see Figure 1 and Figure 2The main support 1 includes a base plate 11, a top plate 12, a first support column 13, and a second support column 14. The base plate 11 and the top plate 12 are spaced apart from each other along a first direction. The first support column 13 and the second support column 14 are both connected between the base plate 11 and the top plate 12. Multiple first support parts 21 are spaced apart and connected to the first support column 13, and multiple second support parts 22 are spaced apart and connected to the second support column 14. Specifically, the base plate 11 and the top plate 12 are both plate-shaped structures with a certain area. The base plate 11 and the top plate 12 can be arranged horizontally, and are generally spaced apart vertically. The first support column 13 and the second support column 14 are both columnar components with a certain height. The two ends of the first support column 13 can be connected to the base plate 11 or the top plate 12 by means of threaded connection, fastener connection, or welding. The two ends of the second support column 14 can be connected to the base plate 11 or the top plate 12 by means of threaded connection, fastener connection or welding. In this embodiment, the base plate 11 and the top plate 12 are spaced apart from each other, and the first support column 13 and the second support column 14 are both connected between the base plate 11 and the top plate 12 to form the main bracket 1. Then, a plurality of first support parts 21 are spaced apart and connected to the first support column 13, and a plurality of second support parts 22 are spaced apart and connected to the second support column 14. The first support parts 21 and the second support parts 22 are arranged correspondingly in the horizontal direction, which makes the installation of the first support parts 21 and the second support parts 22 more convenient and firm, and also makes the overall structure of the main bracket 1 simpler and more robust.

[0042] In an optional embodiment, please refer to Figure 1 and Figure 2 There are multiple first support columns 13 and multiple second support columns 14, and the multiple first support columns 13 and multiple second support columns 14 are arranged parallel to each other. In this embodiment, by using multiple first support columns 13 to support the first support part 21, the first support part 21 can have multiple support points, thereby making the installation of the first support part 21 more stable. Similarly, by using multiple second support columns 14 to support the second support part 22, the second support part 22 can have multiple support points, thereby making the installation of the second support part 22 more stable and improving the stability of the support assembly 2.

[0043] In one embodiment, see Figure 5The first support column 13 is disposed through the first support part 21, and a first spacer sleeve 15 is provided between each two adjacent first support parts 21 to separate them. The first spacer sleeve 15 is fitted onto the outside of the first support column 13. The second support column 14 is disposed through the second support part 22, and a second spacer sleeve 16 is provided between each two adjacent second support parts 22 to separate them. The second spacer sleeve 16 is fitted onto the outside of the second support column 14. Specifically, both the first spacer sleeve 15 and the second spacer sleeve 16 refer to cylindrical structures with a certain height. In this embodiment, the first support column 13 is installed through the first support part 21. The first support part 21 can be limited by the first support column 13 in the radial direction. At the same time, the first spacer sleeve 15 is provided between two adjacent first support parts 21. The first spacer sleeve 15 can support the first support part 21 in the direction along the axis of the first support column 13, so that multiple first support parts 21 can also be fixed at intervals along the axis of the first support column 13. At the same time, the first spacer sleeve 15 is fitted on the outside of the first support column 13, which also makes the installation of the first spacer sleeve 15 more stable. Similarly, by having the second support column 14 pass through the second support portion 22, the second support portion 22 can be limited in the radial direction along the second support column 14. At the same time, a second spacer sleeve 16 is provided between each two adjacent second support portions 22. The second spacer sleeve 16 can support the second support portion 22 in the direction along the axis of the second support column 14, so that multiple second support portions 22 can also be fixed at intervals along the axis of the second support column 14. At the same time, the second spacer sleeve 16 is fitted on the outside of the second support column 14, which also makes the installation of the second spacer sleeve 16 more stable.
