Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, and in particular to an assembly system and its working method. Background Technology

[0002] In the precision electronics and semiconductor industry, product assembly is often inefficient due to differences between various product components. The product's feeding mechanism is most closely related to assembly efficiency. Current feeding mechanisms often use a fork-like structure to move the product in one direction, which makes it difficult to ensure the feeding position for products with poor consistency. Furthermore, the stroke requirements of structures such as cylinder slide rails require a large amount of space in one direction, resulting in a large installation space. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0004] To address this, the present invention provides an assembly system capable of adaptively adjusting the pushing distance of multiple products to ensure that the pushing is completed in place.

[0005] According to a first aspect of the present invention, an assembly system is provided for assembling a product, the product comprising a first assembly and a second assembly, comprising:

[0006] A conveying mechanism, the conveying mechanism being adapted to convey the pre-connected first assembly and second assembly to an assembly station;

[0007] The assembly station includes...

[0008] A dispensing mechanism is used to dispense adhesive onto the pre-connected first assembly.

[0009] A pushing mechanism is attached to the conveying mechanism. The pushing mechanism is used to receive the pre-connected first assembly and second assembly so that the second assembly can be pushed to connect with the first assembly via the pushing mechanism, and the pushing mechanism is adapted to adjust the displacement distance of each corresponding first assembly and second assembly.

[0010] The beneficial effect of this invention is that the conveying mechanism transports the pre-connected first assembly and the second assembly to the pushing mechanism at the assembly station. During the pushing process, the pushing mechanism can adaptively adjust the distance of relative movement between the first assembly and the second assembly according to the received first assembly and the second assembly, so as to adapt to the differences between the first assembly and the second assembly during the assembly process. At the same time, the pushing mechanism can simultaneously drive the first assembly or the second assembly located on the same side to move synchronously, thereby improving the assembly efficiency of the first assembly and the second assembly.

[0011] Preferably, the bottom of the pushing mechanism is provided with a lifting module, which is adapted to extend and retract in the vertical direction so that when the first assembly and the second assembly are conveyed above the lifting module, the lifting module lifts the first assembly and the second assembly to the assembly station.

[0012] Preferably, the conveying mechanism is provided with a blocking module in the conveying direction, and the blocking module is adapted to be lifted in advance to restrict the conveying mechanism from conveying the first assembly and the second assembly.

[0013] More preferably, the dispensing mechanism is positioned horizontally above the conveying mechanism. The dispensing mechanism includes a dispensing device and a three-axis moving mechanism. The dispensing device is connected to the three-axis moving mechanism so that the dispensing device can be driven by the three-axis moving mechanism to dispense adhesive onto the first assembly carried on the conveying mechanism.

[0014] Preferably, the conveying mechanism includes at least a first conveying component and a second conveying component, the first conveying component and the second conveying component being adapted to a carrier for segmented conveying of the product, and the first conveying component and the second conveying component being spaced apart and having the same conveying direction.

[0015] More preferably, the conveying mechanism further includes a drive adjustment device, which is adapted to change the forward and backward movement to the left and right movement. The drive adjustment device includes a cylinder, a cam follower, and a guide block. The cylinder is adapted to drive the cam follower to move left and right along the inclined groove opened on the guide block. The cam follower is connected to the bottom of the pushing mechanism via a connecting plate so that it can drive the pushing mechanism to move forward and backward when the cam follower moves left and right along the guide block.

[0016] Preferably, the conveying mechanism is further provided with an adjusting buffer in the conveying direction, the adjusting buffer being adapted to abut against the driving adjusting device to adjust the front and rear positions of the pushing mechanism.

[0017] Preferably, the contact surfaces between the pushing mechanism and the first and second assembly parts are designed as elastic contact surfaces.

[0018] A second aspect of the present invention provides a method for operating an assembly system, applied to the assembly system described in the first aspect of the present invention, comprising the following steps:

[0019] The product to be assembled is placed on the conveyor mechanism and the first and second assembly parts to be assembled are transferred to the assembly station through the conveyor mechanism.

[0020] Apply adhesive to the first assembly component at the assembly station;

[0021] After the glue is applied, push the first assembly part toward the second assembly part to complete the assembly.

[0022] Preferably, when the first assembly is pushed toward the second assembly for assembly, a fixed pressure must be maintained for a set time after the first assembly and the second assembly are connected.

The objects and other advantages of the invention are realized and obtained in accordance with the structures particularly pointed out in the description, claims and drawings.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0039] In the description of this invention, it should be understood that the terms "front," "rear," "left," "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the 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 the invention. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0040] This assembly system is used to assemble products. The product specifically addressed in this application has a first assembly 4 and a second assembly 5. The first assembly 4 includes a first connecting portion 41 and a conductor portion 42. The second assembly 5 has a "U"-shaped structure and includes a second connecting portion 51. The product assembly is completed by connecting the first connecting portion 41 and the second connecting portion 51. Furthermore, although only the first assembly 4 and the second assembly 5 are listed in this application, it does not mean that this application can only assemble products with two assemblies. The following discussion of the working principle of this assembly system is based on the first assembly 4 and the second assembly 5. However, in principle, this application can also assemble products formed by combining three or more assemblies.

[0041] An assembly system according to a specific embodiment of the present invention, see [link to specific embodiment]. Figure 1 and Figure 6 The assembly system includes a conveying mechanism 1, which can transport the pre-connected first assembly 4 and second assembly 5 to the assembly station, and then perform assembly operations on the first assembly 4 and second assembly 5 at the assembly station.

[0042] The assembly station includes a dispensing mechanism 2 and a pushing mechanism 3. The dispensing mechanism 2 can dispense glue onto the pre-connected first assembly 4. The first assembly 4 to be dispensed and the corresponding second assembly 5 are both located in the pushing mechanism 3. The pushing mechanism 3 is attached to the conveying mechanism 1. Therefore, the pushing mechanism 3 can receive the pre-connected first assembly 4 and the second assembly 5. The pushing mechanism 3 can also hold the second assembly 5 after it reaches the set position, thereby restricting the second assembly 5 from moving horizontally. At this time, the dispensing mechanism 2 dispenses glue onto the first assembly 4. After the glue is dispensed, the pushing mechanism 3 pushes the first assembly 4 and the second assembly 5 together until the first assembly 4 can no longer move relative to the second assembly 5, indicating that the connection between the first assembly 4 and the second assembly 5 is complete.

[0043] The contact surfaces of the pushing mechanism 3 with the first assembly 4 and the second assembly 5 are set as elastic contact surfaces to avoid wear on the first assembly 4 and the second assembly 5 during the docking process of the second assembly 5 and the first assembly 4, thereby improving the overall yield rate.

[0044] Specifically, see Figure 3The pushing mechanism 3 includes a push block corresponding to the first assembly 4 and the second assembly 5. An elastic element 35 is also connected to the push block. With the setting of the elastic element 35, when the push block contacts the first assembly 4 and the second assembly 5 and pushes them to move, the elastic element 35 can adaptively adjust its position according to the difference between the first assembly 4 or the second assembly 5 being connected, so as to ensure that each first assembly 4 and the second assembly 5 can be connected in place. The following is a specific description of the product in this application. For example, the pusher includes a first pusher 33 and a second pusher 34. The outer sides (away from the product side) of the first pusher 33 and the second pusher 34 are respectively provided with elastic baffles 36. The first pusher 33 and the second pusher 34 are arranged along the conveying direction, and each first pusher 33 and the second pusher 34 are arranged at intervals. An elastic element 35 is provided between each first pusher 33 and the second pusher 34 and the elastic baffle 36. The two ends of the elastic element 35 are respectively connected to the elastic baffle 36 and the first pusher 33 or the second pusher 34. Therefore, when it is necessary to abut against the product, the first pusher 33 or the second pusher 34 arranged on the same side can move towards the product direction at the same time, or push the first assembly 4 or the second assembly 5 of the product to move in the opposite direction, thereby realizing multi-cavity pushing and greatly improving product efficiency. Furthermore, since elastic elements 35 are provided between each of the first push blocks 33, the second push blocks 34, and the elastic baffle 36, the first push blocks 33 or the second push blocks 34 can adaptively push the material to the appropriate position according to the size difference and part position of the first assembly 4 and the second assembly 5. It should be noted that the size difference and part position of the first assembly 4 and the second assembly 5 may specifically be due to differences in processing and raw materials during the connection of the first connecting part 41 and the second connecting part 51. For example, the second connecting part 51 may be smaller in overall size during processing, thus preventing the first connecting part 41 from being pushed to the set position during connection. Alternatively, the two sides forming the second connecting part 51 may have an angular deviation, causing the first connecting part 41 to experience excessive lateral pressure from the second connecting part 51 during connection, resulting in the first connecting part 41 not being able to fully penetrate the second connecting part 51.

[0045] More specifically, before connecting the first assembly 4 and the second assembly 5, the carrier 14 used to support the first assembly 4 and the second assembly 5 needs to be lifted. Therefore, a lifting module 31 is provided at the bottom of the pushing mechanism 3. The lifting module 31 can extend and retract in the vertical direction. When the carrier 14 carrying the first assembly 4 and the second assembly 5 is transported to the top of the lifting module 31, the lifting module 31 extends upward to lift the carrier 14 carrying the first assembly 4 and the second assembly 5 and the pushing mechanism 3 to the assembly station for assembly operation.

[0046] The lifting module 31 includes a lifting cylinder and a lifting block. The lifting cylinder is connected to the lifting block. The lifting cylinder can extend and retract in the vertical direction. During the extension and retraction, it can drive the lifting block to move synchronously in the vertical direction. When the lifting block comes into contact with the carrier 14 that carries the first assembly 4 and the second assembly 5, it can drive the carrier 14 to move in the vertical direction.

[0047] See Figure 2 The dispensing mechanism 2 is horizontally positioned above the conveying mechanism 1, enabling it to dispense adhesive onto the first assembly 4 conveyed on the conveying mechanism 1. The dispensing mechanism 2 includes a dispensing device 21 and a three-axis moving mechanism 22. The three-axis moving mechanism 22 includes an X-axis adjustment mechanism, a Y-axis adjustment mechanism, and a Z-axis adjustment mechanism. The dispensing device 21 is mounted on the Z-axis adjustment mechanism. Therefore, the dispensing orientation of the dispensing device 21 can be adjusted according to different positions of the conveying mechanism 1 via the three-axis moving mechanism 22. It should be noted that since this three-axis moving mechanism 22 is a commonly used adjustment device in the art, its structure and movement adjustment method will not be described in detail here.

[0048] See Figures 4 to 5 The conveying mechanism 1 is equipped with a blocking module 32 in its conveying direction. The blocking module 32 is adapted to lift in advance to limit the displacement of the first assembly 4 and the second assembly 5 on the conveying mechanism 1. Furthermore, the conveying mechanism 1 includes a first conveying component 11 and a second conveying component 12. The first conveying component 11 and the second conveying component 12 are adapted to convey products and carriers 14 in segments, and the first conveying component 11 and the second conveying component 12 are spaced apart and have the same conveying direction. That is, a production line has at least a first conveying component 11 and a second conveying component 12 spaced apart. The two conveying components can independently convey products and their carriers 14, or they can cooperate to jointly carry the same product and its carrier 14. The first conveying component 11 and the second conveying component 12 on the same production line have the same conveying direction. In addition, a production line is not limited to only having a first conveying component 11 and a second conveying component 12; more conveying components can be set to extend the conveying distance.

[0049] See Figure 3The conveying mechanism 1 also includes a drive adjustment device 13, which is adapted to adjust the movement direction of the cylinder 131 conveying to the pushing mechanism 3 from forward and backward movement to left and right movement. Specifically, the drive adjustment device 13 includes a cylinder 131, a cam follower 132, and a guide block 133. The cylinder 131 is connected to a limit block 135, and a connecting plate 136 is provided on the limit block 135. The cam follower 132 is provided on the connecting plate 136. Therefore, when the cylinder 131 works, it can drive the limit block 135 and the cam follower 132 provided on the connecting plate 136 to move synchronously. At this time, the cam follower 132 can move forward and backward. The guide block 133 has a groove, and the cam follower 132 is located in the groove. Therefore, the forward and backward movement of the cam follower 132 is along the groove on the guide block 133. The cam follower 132 is connected to a slider connecting plate 136. Under the drive of the cam follower 132, the slider connecting plate 136 simultaneously drives the elastic baffle 36 connected to it to move along the linear slide rail 137 which is perpendicular to the conveying direction of the conveying mechanism 1. That is, through the cam follower 132, the forward and backward motion can be converted into left and right motion, thereby reducing the space occupied by the conveying mechanism 1 and the drive adjustment device 13, making it easier to arrange in a small space.

[0050] Specifically, an adjusting buffer 134 is provided in the conveying direction of the conveying mechanism 1. The adjusting buffer 134 can abut against the limiting block 135. By controlling the position of the limiting block 135, the front and rear positions of the entire pushing mechanism 3 can be further controlled, thereby achieving the effect of adjusting the position of the product during assembly.

[0051] A second aspect of the present invention provides a method for operating an assembly system, applicable to the assembly system described in any of the above embodiments of the present invention, the method comprising the following steps:

[0052] The product to be assembled is placed on the conveyor mechanism 1, and the first assembly 4 and the second assembly 5 to be assembled are transferred to the assembly station through the conveyor mechanism 1.

[0053] At the assembly station, apply adhesive to the first assembly part 4;

[0054] After the glue is applied, push the first assembly 4 and the second assembly 5 together to complete the assembly.

[0055] The first assembly 4 can be a transistor, a raw material for manufacturing Hall effect sensors. This transistor has a first connecting portion 41 and a conductor portion 42. The second assembly 5 can be a silicon steel sheet with a "U"-shaped structure, forming a protective element assembled on the first connecting portion 41. The second assembly 5 has a second connecting portion 51 that engages with the first connecting portion 41. A first pusher 33 is adapted to push the first connecting portion 41 of the first assembly 4 to move, and a second pusher 34 is adapted to push the end of the second assembly 5 to move. Before pushing the first assembly 4 and the second assembly 5 to move, adhesive needs to be applied to the first assembly 4 at the assembly station. Adhesive application should be done on the first connecting portion 41 of the transistor. When the first connecting portion 41 and the second connecting portion 51 are assembled, only a portion of the adhesive applied to the first connecting portion 41 overflows, with the remainder suitable for bonding the first connecting portion 41 and the second connecting portion 51.

[0056] Furthermore, when assembling the first assembly 4 and the second assembly 5 after dispensing, the pusher mechanism 3 pushes the first assembly 4 and the second assembly 5 to dock until the pusher mechanism 3 can no longer push the first assembly 4 and the second assembly 5 closer together. This indicates that the docking of the first assembly 4 and the second assembly 5 is complete. In this state, the pusher mechanism 3 will maintain the docking state of the first assembly 4 and the second assembly 5 and maintain the pressure applied to the first assembly 4 and the second assembly 5 for a set time before releasing it. By maintaining the pressure on the first assembly 4 and the second assembly 5, it is possible to avoid the first assembly 4 and the second assembly 5 from being unable to form an effective connection and separating after dispensing because the glue has not yet solidified. This would result in defects after the first assembly 4 and the second assembly 5 are connected and assembled, affecting the yield of the final product.
