Detailed Implementation

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0068] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0069] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0070] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0071] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0072] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0073] In the field of semiconductor packaging technology, the Easy2B package for IGBT (Insulated Gate Bipolar Transistor) modules requires the assembly of the housing and the base plate. Currently, the assembly method involves some automated processes and others manual assembly, representing a semi-automated production process. The assembly process is roughly as follows: sealant is applied to the bottom perimeter of the housing using a sealant coating machine. Then, the coated housing and the base plate are manually assembled, pressing them together by hand. After assembly, the housing is manually placed into a tray for subsequent processing.

[0074] In this assembly method, manual operations include picking up the base plate and the outer shell separately, pressing the base plate and the outer shell together, and then placing the assembled product into a specific tray. The increased human contact with, handling, and transporting of the product leads to longer assembly time, lower efficiency, and product quality risks introduced by the uncontrollability of human operation. For example, the sealant bonding surfaces may detach during transfer, or the pressing force may be difficult to control, resulting in poor product consistency, thus affecting product quality.

[0075] To overcome at least one of the shortcomings in the prior art, this embodiment provides a fully automated assembly method that can improve assembly efficiency, enhance product quality, and ensure better consistency of batch products.

[0076] First Embodiment

[0077] Please refer to Figure 1This embodiment provides a method for assembling the outer shell 200 and the base plate 300, the main steps of which are as follows:

[0078] S1: Apply adhesive to the outer casing 200.

[0079] S2: Move the outer casing 200 to the outer casing mounting position 250.

[0080] S3: Move the base plate 300 to the base plate installation position; wherein, the base plate installation position is provided with a lifting mechanism 310, and the lifting mechanism 310 is located below the base plate 300.

[0081] S4: The lifting mechanism 310 moves the base plate 300 to the preset position.

[0082] S5: Obtain the first coordinate position of the base plate 300.

[0083] S6: Move the outer casing 200 from the casing mounting position 250 to above the base plate 300.

[0084] S7: Obtain the second coordinate position of the outer shell 200.

[0085] S8: Adjust the base plate 300 and the outer shell 200 to align according to the first coordinate position and the second coordinate position.

[0086] S9: Press the outer shell 200 and the base plate 300 together to form the target product 400.

[0087] S10: The lifting mechanism 310 moves the target product 400 to the bottom plate waiting position.

[0088] Combination Figure 2 and Figure 3 In step S1, an adhesive applicator unit automatically applies adhesive to the housing 200. The housing 200 is provided with an adhesive applicator groove 210. The applicator needle moves along the adhesive applicator groove 210 at a preset speed and dispenses adhesive according to a preset flow rate. Optionally, the housing 200 is conveyed to a clamp 220 at the sealant application position, and the clamp 220 is used to fix the housing 200. The sealant application needle is installed and fixed at the application needle position of the adhesive applicator unit. The adhesive application path is planned according to the shape of the adhesive applicator groove 210 on the inner side of the housing 200, and the travel path program of the application needle is set. According to the preset program, the application needle will move along the adhesive application path on the inner side of the housing 200 at a set travel speed under the drive of the robotic arm, and simultaneously, sealant is supplied to the application needle. The sealant is squeezed according to the set screw speed and evenly applied in a circle along the adhesive application path on the inner side of the housing 200 with the application needle.

[0089] Combination Figure 4After applying the adhesive, the quality of the adhesive application on the outer casing 200 is inspected. Optionally, a robotic arm is used to pick up the outer casing 200 and transfer it to the inspection station 230. The inspection station 230 is equipped with an inspection camera 240, such as a CCD camera. The inspection camera 240 is used to inspect the appearance of the sealant application. If the inspection is qualified, step S2 is performed. The glued outer casing 200 is then transferred to the outer casing waiting position 250. It is understood that the inspection camera 240 can be positioned above the inspection station 230 to clearly capture the appearance of the sealant application on the outer casing 200. The outer casing waiting position 250 can be a tray or other fixture used to store the glued outer casing 200. If the appearance of the sealant application fails the inspection, the sealant is reapplied, or the unqualified outer casing 200 is stored separately for centralized processing.

[0090] Combination Figure 5 In step S3, the base plate 300 is moved to the base plate assembly position. Optionally, the entire tray of base plates 300, which has been pre-placed in the pallet 100, is placed into a loading machine. The loading machine rises and then, via a slide rail, delivers the entire tray of base plates 300 and the pallet 100 together to the base plate assembly position. In some embodiments, the base plate 300 can be pre-placed in the base plate assembly position, and the pre-applied adhesive outer shell 200 can be pre-placed in the outer shell assembly position, thus omitting steps S1 to S3.

[0091] Combination Figure 6 and Figure 7 It can be understood that the pallet 100 is located at the base plate assembly position, and the lifting mechanism 310 is located below the pallet 100. The pallet 100 has multiple placement stations 110, each used to place one base plate 300 or one target product 400. Each placement station 110 has a through hole 111 through which the lifting mechanism 310 passes. The pallet 100 has a first support portion 112 and a second support portion 113 for supporting the base plate 300, located on both sides of the through hole 111. A pallet 100 has multiple through holes 111, and each through hole 111 has a first support portion 112 and a second support portion 113 on both sides. Each through hole 111 can hold one base plate 300 to be assembled. There can be multiple lifting mechanisms 310, corresponding one-to-one with the through holes 111. Alternatively, the lifting mechanism 310 can be a single unit that can be moved to below any of the through holes 111 as needed to assist in the assembly of the base plate 300 and the outer casing 200 within that through hole 111. During assembly, the lifting mechanism 310 can provide support for the base plate 300.

[0092] In this embodiment, a single lifting mechanism 310 is used to assemble one base plate 300 and one outer shell 200 at a time. After assembly, the lifting mechanism 310 moves to the next through hole 111 to complete the assembly of the next base plate 300 and outer shell 200.

[0093] Combination Figure 8In step S4, the lifting mechanism 310 pushes the base plate 300 upwards, detaching it from the tray 100. The lifting mechanism 310 then passes through the through hole 111 of the tray 100, supporting the base plate 300. The lifting height of the base plate 300 is set according to actual needs and is not specifically limited here. Of course, in some embodiments, the lifting height can also be zero, that is, the base plate 300 is assembled with the outer shell 200 inside the tray 100; this is not specifically limited here. In this embodiment, to facilitate the rotation of the product later, the lifting mechanism 310 drives the base plate 300 to rise, such as with a lifting height of 5mm to 50mm.

[0094] Combination Figure 9 In step S5, the method for obtaining the first coordinate position of the base plate 300 is as follows:

[0095] A recognition model for the base plate 300 is generated based on preset markings on the base plate 300. These preset markings can be special graphics or dedicated markers on the base plate 300 to facilitate automatic image recognition in the program. First preset coordinates are calculated based on the base plate 300 recognition model. Using the base plate 300 recognition model, the software acquires image information of the model and converts it into coordinate position information, thus obtaining the first preset coordinates.

[0096] The actual image of the base plate 300 is acquired. An image capture unit 320, such as a CCD camera, is used to acquire the actual image of the base plate 300. It is then determined whether the actual image matches the recognition model of the base plate 300. If the actual image matches the recognition model, the first coordinate position of the base plate 300 is calculated based on the actual image. The conversion rule for converting the recognition model of the base plate 300 to the first preset coordinates is consistent with the conversion rule for converting the actual image of the base plate 300 to the first coordinate position. By determining whether the actual image matches the recognition model of the base plate 300, the specifications and model of the base plate 300 to be assembled can be detected, preventing the misassembly of base plates 300 of different models. Simultaneously, it can also serve as a positioning reference for the subsequent assembly of the outer shell 200.

[0097] Combination Figure 10 In step S6, the outer casing 200 is moved from the outer casing mounting position 250 to above the base plate 300. A transfer unit 260, such as a robotic arm, can be used to transfer the outer casing 200. In this embodiment, the transfer of one outer casing 200 at a time is used as an example. Of course, in some embodiments, the outer casings 200 can be transferred in batches to achieve batch assembly of the outer casings 200 and the base plate 300. This is not specifically limited here.

[0098] Move the outer casing 200 from the casing mounting position 250 to above the base plate 300; at this time, the glued surface of the outer casing 200 is facing upwards. It is necessary to rotate the outer casing 200 degrees so that the glued surface of the outer casing 200 is facing downwards, that is, the glued surface of the outer casing 200 is facing the base plate 300. In this state, obtain the second coordinate position of the outer casing 200.

[0099] Similarly, in step S7, the method for obtaining the second coordinate position of the outer shell 200 is similar to that in step S5, as follows:

[0100] A shell 200 model is generated based on preset markings on the shell 200. Second preset coordinates are calculated based on the shell 200 model; an actual image of the shell 200 is acquired. It is determined whether the actual image matches the shell 200 model; if the actual image matches the shell 200 model, the second coordinate position of the shell 200 is calculated based on the actual image. Optionally, the operator selects the position of a special graphic (i.e., preset markings) on the shell 200 using a CCD camera or other imaging unit 320, and selects the special graphic as an image recognition template (i.e., the shell 200 model). Through the creation of the image recognition template for the shell 200, the software-acquired image information of the shell 200 is converted into coordinate position information. The actual image of the shell 200 and the image recognition template are compared to confirm whether the current position of the actual image of the shell 200 matches the position of the shell 200 model. By comparing the shell 200 model, the coordinates of the actual image of the shell 200 are calculated to obtain the second coordinate position of the shell 200.

[0101] Combination Figure 11 In step S8, there are several ways to align the base plate 300 and the outer shell 200. For example, the first method involves fixing the base plate 300 and adjusting the position of the outer shell 200 so that the projections of the first and second coordinate positions on the horizontal plane coincide. If the horizontal plane is a plane composed of the X and Y axes with the origin at O, then the coordinates of the outer shell 200 and the base plate 300 on the XOY plane (horizontal plane) are the same, but their coordinates in the Z-axis height direction are different. In this way, the outer shell 200 descends linearly under the drive of the robotic arm, allowing it to press and assemble with the base plate 300. The second method involves moving the base plate 300 while keeping the outer shell 200 stationary, adjusting their coordinates on the horizontal plane to be the same. The third method involves moving the base plate 300 and the outer shell 200 simultaneously to make their coordinates on the horizontal plane the same. Of course, in some implementations, while adjusting the position of the horizontal plane, the two can be brought closer to each other, so that the three-dimensional coordinates of the outer shell 200 and the base plate 300 coincide in the spatial range, that is, the first coordinate position and the second coordinate position coincide, so as to facilitate alignment and pressing.

[0102] In this embodiment, the base plate 300 is fixed, while the outer shell 200 moves under the drive of the robotic arm. As it approaches the base plate 300, the position of the outer shell 200 is adjusted so that the three-dimensional coordinates of the outer shell 200 and the base plate 300 coincide in the spatial range.

[0103] Combination Figure 12 In step S9, after the coordinates of the two coincide, a certain pressure is applied to the outer shell 200 to bond and fix the outer shell 200 and the base plate 300, thereby improving the bonding reliability and completing the assembly to form the target product 400. The pressure applied to the outer shell 200 can be a preset fixed value, which can ensure that the pressing force of all products is equal during the assembly process, thereby improving the consistency of product assembly.

[0104] Combination Figure 13 In step S10, the lifting mechanism 310 drives the target product 400 to rotate by a preset angle. In this embodiment, the preset angle is 90 degrees, that is, the lifting mechanism 310 rotates 90 degrees to drive the target product 400 to rotate 90 degrees. Of course, in other embodiments, the preset angle can be flexibly set according to actual needs, such as any angle from 20 degrees to 130 degrees, which can be 60 degrees, 70 degrees, 80 degrees, 100 degrees or 120 degrees, etc., and is not specifically limited here.

[0105] Combination Figure 14 The rotated target product 400 is moved to the base plate mounting position. After the lifting mechanism 310 rotates, it descends into the tray 100 at a set speed. The tray 100 is provided with a third support portion 114 and a fourth support portion 115 located on both sides of the through hole 111. The third support portion 114 and the fourth support portion 115 are used to support the rotated target product 400. In this embodiment, the line connecting the first support portion 112 and the second support portion 113 is approximately 90 degrees to the line connecting the third support portion 114 and the fourth support portion 115. It should be noted that the base plate 300 before assembly and the target product 400 after assembly are both stored in the base plate mounting position, that is, in the same workstation, only the placement angle is adjusted. Since the base plate 300 before assembly and the target product 400 after assembly differ in weight, volume, center of gravity and appearance, and considering the actual structure of the pallet 100, rotating it 90 degrees after assembly can provide better support for the target product 400, making it more stable and easier to place.

[0113] Other parts not mentioned in this embodiment are similar to those described in the first embodiment and will not be repeated here.

[0114] The assembly method of the outer shell 200 and the base plate 300 provided in this embodiment of the invention involves applying adhesive to the outer shell 200 and placing it in the shell assembly position 250 for later use. Multiple base plates 300 are pre-placed in a tray 100, and the tray 100 is conveyed to the base plate assembly position by a loading machine. A lifting mechanism 310 below the base plate assembly position passes through the through hole 111 of the tray 100 and pushes the base plate 300 out to a preset height, obtaining the first coordinate position of the base plate 300 using a CCD camera. The outer shell 200 is moved above the base plate 300, and the outer shell 200 is flipped so that its mating surface faces the base plate 300, obtaining the second coordinate position of the outer shell 200. The outer shell 200 is moved closer to the base plate 300, and its position is adjusted in real time during the movement to ensure that the first and second coordinate positions coincide, achieving precise positioning. Finally, the outer shell 200 and the base plate 300 are pressed together to complete the assembly, forming the target product 400. The lifting mechanism 310 rotates the target product 400 by 90 degrees and then lowers it to the mounting position on the base plate. The lifting mechanism 310 then moves to the next through hole 111 of the tray 100, pushes out the next base plate 300, and the robot grabs the next outer shell 200 and places it above the base plate 300. The steps of moving, positioning, pressing, rotating and lowering are repeated to achieve the assembly of the base plate 300 and the outer shell 200.

[0115] In summary, this invention provides a method, apparatus, and storage medium for assembling a housing 200 and a base plate 300. The assembly of the base plate 300 and housing 200 can be automated, resulting in high assembly efficiency. The base plate 300 before assembly and the target product 400 after assembly can be placed in the same position, i.e., the base plate waiting position. This avoids the need to switch pallets 100, reduces the number of product transfers, shortens assembly time, and improves production efficiency. It also avoids damage to the product during transfer, resulting in higher product yield and better quality. Furthermore, the fully mechanized operation avoids the uncontrollable and subjective factors of manual operation, leading to better consistency and higher assembly precision in product assembly.
