Description

Technical Field

[0001] This utility model relates to the field of chip mounting technology, specifically to a material feeding and conveying device. Background Technology

[0002] A eutectic bonding machine is a specialized piece of equipment used for eutectic bonding, primarily in fields such as microelectronic packaging, optoelectronic device assembly, and MEMS (Micro-Electro-Mechanical Systems) manufacturing. Eutectic bonding utilizes the eutectic reaction to achieve high-precision, high-reliability material connections. The eutectic reaction leverages the property of two or more materials forming a low-melting-point alloy in a specific ratio. This eutectic alloy solidifies rapidly after melting, forming a dense, low-stress bonding layer.

[0003] Current eutectic bonding machines typically operate by placing a substrate carrier containing materials into the loading / unloading module. The module then moves horizontally, and the pick-up arm moves vertically to sequentially pick up the materials and transfer them to the thermal bonding platform. The platform heats the materials before transferring them under the thermal bonding head for eutectic bonding. Finally, the pick-up arm places the eutectic bonded materials back onto the substrate carrier. However, current applications use a single-station loading / unloading module, and the entire material processing is sequential—loading, bonding, bonding, and unloading are all completed before the next material is loaded. This results in slow loading / unloading speeds and low bonding efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to provide a material feeding and conveying device that can improve the loading and unloading speed, thereby effectively improving the equipment's patching efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A material feeding and conveying device includes a body, on which a loading and unloading mechanism and a multi-station mechanism are provided;

[0007] The loading and unloading mechanism includes a tray and a loading and unloading module. The tray has multiple material receiving slots for placing materials. The loading and unloading module includes an axial motion component, a longitudinal motion component, and a material adsorption component. The fixed end of the axial motion component is mounted on the machine body via a loading and unloading base. The fixed end of the longitudinal motion component is connected to the moving end of the axial motion component. The material adsorption component is connected to the moving end of the longitudinal motion component, so that the axial motion component and the longitudinal motion component can drive the material adsorption component to move axially and longitudinally, respectively. The material adsorption component includes a vertically arranged linear motor and a vacuum nozzle. The linear motor is mounted on the moving end of the longitudinal motion component, and its power shaft is connected to the vacuum nozzle, so that the linear motor can drive the vacuum nozzle to move vertically.

[0008] The multi-station mechanism includes a first longitudinal motion component. The fixed end of the first longitudinal motion component is mounted on the machine body. The moving end of the first longitudinal motion component is provided with a first station module and a second station module along the longitudinal direction. The first longitudinal motion component is used to drive the first station module and the second station module to move longitudinally.

[0009] Thus, the working principle of this solution is as follows: When the material feeding and conveying device of this solution is in use, the material is placed in the material receiving slot of the pallet. When it is necessary to place the material on the pallet into the first or second station module, or to put the material on the first or second station module back onto the pallet, the position of the material adsorption component is first adjusted according to the position of the material. The axial movement component of the loading and unloading mechanism can drive the material adsorption component to move axially, and the longitudinal movement component of the loading and unloading mechanism can drive the material adsorption component to move longitudinally. When the material adsorption component reaches directly above the material through the axial and longitudinal movements, the linear motor for material adsorption is activated, and the material adsorption linear motor... The linear motor drives the vacuum nozzle to move vertically downwards, bringing it into contact with and adsorbing the material. Once the vacuum nozzle has adsorbed the material, the material adsorption linear motor drives the vacuum nozzle to move vertically upwards. Then, the material adsorption assembly is further moved axially and longitudinally by the loading and unloading axial and longitudinal motion components to directly above the first or second workstation module. The material adsorption linear motor is then activated again, driving the vacuum nozzle to move vertically downwards, placing the material onto the first or second workstation module. Finally, the material adsorption linear motor drives the vacuum nozzle to move vertically upwards again.

[0010] After the material on the first or second workstation module is processed, the material adsorption linear motor drives the vacuum nozzle to move vertically downwards, causing the vacuum nozzle to adsorb the material on the first or second workstation module. Once the vacuum nozzle has adsorbed the material, the material adsorption linear motor drives the vacuum nozzle to move vertically upwards. Then, through the loading / unloading axial and longitudinal motion components, the material adsorption component moves axially and longitudinally to the designated placement position on the tray. The material adsorption linear motor then drives the vacuum nozzle to move vertically downwards again, placing the material in the corresponding position. After the material is placed, the material adsorption linear motor drives the vacuum nozzle to move vertically upwards again, preparing for the next loading / unloading operation.

[0011] Therefore, this solution, through the axial and longitudinal movement of the material adsorption component, can adsorb materials at any position on the tray and place the adsorbed materials onto the first or second workstation module, or re-adsorb the processed materials from the first or second workstation module and place them back onto the tray. Simultaneously, this solution sets up a first and second workstation module along the longitudinal direction. When the first workstation module finishes loading and moves longitudinally to the next workstation, the second workstation module moves to the position corresponding to the loading / unloading mechanism. This allows the loading / unloading mechanism to load or unload materials from the second workstation module while the materials from the first workstation module are being processed at the next workstation; similarly, when the second workstation module moves to the next workstation for further processing, the first workstation module moves to the position corresponding to the loading / unloading mechanism. This allows the first and second workstation modules to process materials simultaneously. Compared to the existing technology where all materials are processed before the next material is loaded, this solution significantly improves the loading and unloading speed and also enhances the overall efficiency of the patch panel.

[0012] In summary, this utility model adopts a dual-station feeding structure, and each station can feed multiple sets of materials at once. The dual stations feed materials in a cyclical manner. While one station loads and unloads materials, the other station performs the next step of chip mounting, realizing the synchronous processing of loading, unloading and mounting, which greatly improves the chip mounting efficiency.

[0013] Preferably, both the first workstation module and the second workstation module are flipping modules. The flipping module includes a flipping motor and a flipping block. The flipping motor is mounted on the first longitudinal motion component via a motor mounting base, so that the first longitudinal motion component drives the flipping motor to move longitudinally. The flipping block is connected to the rotating shaft of the flipping motor, so that the rotation of the flipping motor drives the flipping block to rotate. The flipping block is provided with a material placement slot and a material heating rod. The material placement slot is used to place materials, and the materials are always kept in the material placement slot during the rotation of the flipping block. The material heating rod is used to heat the materials in the material placement slot.

[0014] In this way, when it is necessary to apply a patch to the side of the material, the rotation of the flipping motor drives the flipping block to rotate, which in turn rotates the material, ensuring that the surface of the material to be patched is aligned with the patching mechanism. The material placement slot on the flipping block prevents the material from falling off after flipping. The material heating rod heats the material, and simultaneously, as the flipping module moves longitudinally along the first longitudinal motion component, it can simultaneously flip and heat the material, thereby further improving the overall efficiency of material handling.

[0015] Preferably, the flipping block is provided with a plurality of material placement slots along the longitudinal direction, and a material heating rod is provided at each of the material placement slots.

[0016] In this way, by setting up multiple material placement slots and installing a material heating rod at each material placement slot, the flipping module can transport multiple materials at one time, and each material can be heated by a corresponding material heating rod, ensuring the uniformity of material heating.

[0017] Preferably, both the first workstation module and the second workstation module are rapid heating modules. The rapid heating module includes a rapid heating base, which is mounted on the first longitudinal motion component. A rapid heating component is provided on the rapid heating base, and materials are placed on the rapid heating component to heat the materials.

[0018] In this way, when it is not necessary to apply patches to the sides of the material, both the first station module and the second station module can be set as rapid heating modules to quickly heat the material. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] The material feeding and conveying device in this solution can be used on a eutectic machine, as shown in the attached diagram. Figure 1 and attached Figure 2 The image shows a eutectic crystallizer with a material feeding and conveying device according to this scheme. The material feeding and conveying device of this scheme (including attachments) Figure 1The loading / unloading mechanism 2 and the multi-station mechanism 3 in the machine mainly pick up materials from the tray sequentially and place them onto the first or second station module. Then, the first longitudinal motion component drives the first or second station module to move to the placement mechanism 4 for placement processing. To achieve synchronous loading / unloading and placement, a loading / unloading mechanism 2 can be set on each of the two longitudinal sides of the machine body, with the placement mechanism 4 located between the two loading / unloading mechanisms, as shown in the attached figure. Figure 1 As shown, this allows one workstation module to perform loading and unloading operations in tandem with the corresponding loading and unloading mechanism while the other workstation module is in the placement phase. Alternatively, a loading and unloading mechanism 2 can be set up, with two placement mechanisms 4 positioned on either side of its longitudinal direction. This also allows one workstation module to perform loading and unloading operations in tandem with the corresponding loading and unloading mechanism while the other workstation module is in the placement phase. Therefore, this solution does not impose any restrictions on the specific structural form.

[0028] The material feeding and conveying device of this scheme will be described in detail below with reference to the attached drawings:

[0029] Example 1:

[0030] The material feeding and conveying device of this solution includes a machine body, on which a loading and unloading mechanism and a multi-station mechanism are provided;

[0031] As attached Figure 3 and attached Figure 4 As shown, the loading and unloading mechanism 2 includes a tray 201 and a loading and unloading module. The tray 201 is provided with multiple material receiving slots for placing materials. The loading and unloading module includes a loading and unloading axial motion component 203, a loading and unloading longitudinal motion component 204, and a material adsorption component. The fixed end of the loading and unloading axial motion component 203 is mounted on the machine body 1 through the loading and unloading base 202. The fixed end of the loading and unloading longitudinal motion component 204 is connected to the moving end of the loading and unloading axial motion component 203. The material adsorption component is connected to the moving end of the loading and unloading longitudinal motion component 204, so that the loading and unloading axial motion component 203 and the loading and unloading longitudinal motion component 204 can drive the material adsorption component to move axially and longitudinally, respectively. The material adsorption component includes a material adsorption linear motor 205 and a vacuum nozzle 206 arranged vertically. The material adsorption linear motor 205 is mounted on the moving end of the loading and unloading longitudinal motion component 204, and the power shaft of the material adsorption linear motor 205 is connected to the vacuum nozzle 206, so that the material adsorption linear motor 205 can drive the vacuum nozzle 206 to move vertically.

[0032] As attached Figure 5As shown, the multi-station mechanism 3 includes a first longitudinal motion component 304. The fixed end of the first longitudinal motion component 304 is mounted on the machine body 1. The moving end of the first longitudinal motion component 304 is provided with a first station module and a second station module along the longitudinal direction. The first longitudinal motion component 304 is used to drive the first station module and the second station module to move along the longitudinal direction.

[0033] Thus, the working principle of this solution is as follows: When the material feeding and conveying device of this solution is in use, the material is placed in the material receiving slot of the pallet 201. When it is necessary to place the material on the pallet 201 into the first station module or the second station module, or to put the material on the first station module or the second station module back onto the pallet 201, the position of the material adsorption component is first adjusted according to the position of the material. The axial movement component 203 can drive the material adsorption component to move axially, and the longitudinal movement component 204 can drive the material adsorption component to move longitudinally. When the material adsorption component reaches directly above the material through the axial and longitudinal movements, the material adsorption linear motor 205 is activated, and the material adsorption linear motor 205 drives the vacuum nozzle. The vacuum nozzle 206 moves downwards vertically, bringing it into contact with and adsorbing the material. Once the vacuum nozzle 206 has adsorbed the material, the material adsorption linear motor 205 drives the vacuum nozzle 206 upwards vertically. Then, the material adsorption assembly is further moved axially and longitudinally by the loading / unloading axial motion assembly 203 and the loading / unloading longitudinal motion assembly 204 to directly above the first or second workstation module. The material adsorption linear motor 205 is then activated again, driving the vacuum nozzle 206 downwards vertically, placing the material onto the first or second workstation module. Finally, the material adsorption linear motor 205 drives the vacuum nozzle 206 upwards vertically.

[0034] After the material on the first or second workstation module is processed, the material adsorption linear motor 205 drives the vacuum nozzle 206 to move vertically downwards, causing the vacuum nozzle 206 to adsorb the material on the first or second workstation module. Once the vacuum nozzle 206 has adsorbed the material, the material adsorption linear motor 205 drives the vacuum nozzle 206 to move vertically upwards. Then, the loading / unloading axial motion component 203 and the loading / unloading longitudinal motion component 204 drive the material adsorption component to move axially and longitudinally to the designated placement position on the tray 201. The material adsorption linear motor 205 then drives the vacuum nozzle 206 to move vertically downwards to place the material in the corresponding position. After the material is placed, the material adsorption linear motor 205 drives the vacuum nozzle 206 to move vertically upwards for the next loading / unloading operation.

[0035] Therefore, this solution, through the axial and longitudinal movement of the material adsorption component, can adsorb materials at any position on the tray 201 and place the adsorbed materials onto the first or second station module, or re-adsorb the processed materials from the first or second station module and place them back onto the tray 201. Simultaneously, this solution sets up a first and second station module along the longitudinal direction. When the first station module finishes loading and moves longitudinally to the next station, the second station module moves to the position corresponding to the loading / unloading mechanism 2. This allows the loading / unloading mechanism 2 to load or unload materials from the second station module while the materials from the first station module are being processed at the next station. Similarly, when the second station module moves to the next station for further processing, the first station module moves to the position corresponding to the loading / unloading mechanism 2. This allows the first and second workstation modules to process materials simultaneously. Compared to the existing technology where all materials are processed before the next material is loaded, this solution significantly improves the loading and unloading speed and also enhances the overall efficiency of the patch panel.

[0036] In summary, this utility model adopts a dual-station feeding structure, and each station can feed multiple sets of materials at once. The dual stations feed materials in a cyclical manner. While one station loads and unloads materials, the other station performs the next step of chip mounting, realizing the synchronous processing of loading, unloading and mounting, which greatly improves the chip mounting efficiency.

[0037] For example, see appendix. Figure 5 As shown, in this embodiment, both the first workstation module and the second workstation module are flipping modules. The flipping module includes a flipping motor 301 and a flipping block 302. The flipping motor 301 is mounted on the first longitudinal motion component 304 through a motor mounting base so that the first longitudinal motion component 304 drives the flipping motor 301 to move longitudinally. The flipping block 302 is connected to the rotating shaft of the flipping motor 301 so that the rotation of the flipping motor 301 drives the flipping block 302 to rotate. The flipping block 302 is provided with a material placement slot and a material heating rod 303. The material placement slot is used to place materials and keeps the materials in the material placement slot during the rotation of the flipping block 302. The material heating rod 303 is used to heat the materials in the material placement slot.

[0038] Thus, when patching is required on the side of the material, the rotation of the flipping motor 301 drives the flipping block 302 to rotate, which in turn rotates the material, ensuring that the surface of the material to be patched faces the patching mechanism 4. The material placement slot on the flipping block 302 prevents the material from falling after flipping. The material heating rod 303 heats the material, and simultaneously, as the flipping module moves longitudinally along the first longitudinal motion component 304, it can simultaneously flip and heat the material, thereby further improving the overall efficiency of material handling.

[0039] In this embodiment, a plurality of material placement slots are provided on the flipping block 302 along the longitudinal direction, and a material heating rod 303 is provided at each material placement slot.

[0040] In this way, by setting up multiple material placement slots and installing a material heating rod 303 at each material placement slot, the flipping module can transport multiple materials at one time, and each material can be heated by a corresponding material heating rod 303 to ensure the uniformity of material heating.

[0041] It should be noted that the loading / unloading axial motion component 203 in this solution achieves linear motion in the axial direction at the corresponding position, while the loading / unloading longitudinal motion component 204 and the first longitudinal motion component 304 achieve linear motion in the longitudinal direction at the corresponding position. This linear motion can be achieved using a linear motor and linear guide structure, or a slider and guide structure, etc. These structural forms for achieving linear motion are all existing technologies. Those skilled in the art can choose the specific structure according to actual design needs. Moreover, the implementation of this linear structure will not have a substantial impact on this solution, will not cause ambiguity to this technical solution, and is not a technical solution that needs to be protected in this solution. Therefore, it will not be discussed in detail in this solution.

[0042] To provide a clearer understanding of the working process of the material feeding and conveying device in this solution, the following is a more detailed explanation of the overall working process of the eutectic machine equipped with the material feeding and conveying device of this solution:

[0043] In this specific embodiment, the example is that one loading / unloading mechanism 2 is provided on each of the longitudinal sides of the body 1. Of course, other arrangements are possible in actual use. When the eutectic machine with the material loading and conveying device of this solution is working, the material to be processed is first placed on the trays 201 of the two loading / unloading mechanisms 2. Then, the loading / unloading module places the material to be processed on the trays 201 onto the first and second station modules of the multi-station mechanism 3. Then, the first longitudinal motion component 304 moves along the first longitudinal direction, so that the first station module moves to the position corresponding to the bonding mechanism 4, and at this time, the second station module moves to the position corresponding to the loading / unloading mechanism 2. Of course, in specific operation, the second station module can be moved to the position corresponding to the bonding mechanism 4 first, and the first station module can be moved to the position corresponding to the loading / unloading mechanism 2. This does not have a substantial impact on the operation of the eutectic machine of this solution. During the process of the first station module moving toward the patching mechanism 4, when it is necessary to patch the side of the material, the flipping motor 301 drives the flipping block 302 to move, causing the material to flip and move to the corresponding position of the patching mechanism 4, and then the patching mechanism 4 performs patching on the surface of the material. When the materials on the first station module are being soldered and chip bonded, the loading / unloading mechanism 2 corresponding to the second station module places the processed materials back onto the tray 201 and places new materials to be processed onto the second station module. When all the materials on the first station module have been processed, the first longitudinal motion component 304 moves along the second longitudinal direction, causing the second station module to move to the position corresponding to the placement mechanism 4. At this time, the first station module moves to the position corresponding to the loading / unloading mechanism 2. Then, the placement mechanism 4 performs placement processing on the materials on the second station module. When all the materials on the second station module have been processed, the first longitudinal motion component 304 moves along the first longitudinal direction, causing the first station module to move back to the position corresponding to the placement mechanism 4, and the second station module moves to the position corresponding to the loading / unloading mechanism 2. This allows the second station module to perform material loading and unloading operations while the first station module is performing solder bonding and chip bonding, and vice versa.

[0044] Example 2:

[0045] The difference from Embodiment 1 is that, as shown in the appendix Figure 6 As shown, in this embodiment, both the first station module and the second station module are rapid heating modules 305. The rapid heating module 305 includes a rapid heating base, which is mounted on the first longitudinal motion component 304. A rapid heating component is provided on the rapid heating base, and materials are placed on the rapid heating component to heat the materials.

[0046] In this way, when it is not necessary to apply a patch to the side of the material, both the first station module and the second station module can be set as rapid heating modules 305, and the rapid heating modules 305 can be used to rapidly heat the material.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
