Description

Technical Field

[0001] This utility model relates to the field of semiconductor equipment technology, and specifically to a mounting device for SMT chip assembly. Background Technology

[0002] SMT refers to circuit boards. During the production of frequency converters, circuit boards need to be placed on a pick-and-place machine for placement before they can be installed on the frequency converter. The board mounting machine is a device used to automatically move the circuit board onto the pick-and-place machine.

[0003] Currently, when receiving boards at the board loading station, it is impossible to correct the position of misaligned boards, causing them to remain offset while on the board loading station. Severe misalignment may even lead to collisions with the conveyor belt, hindering subsequent processing and increasing waste. To address this, we propose a board loading device for SMT assembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a board loading device for SMT assembly. By installing a correction component on the first conveyor belt, the position of the board can be adjusted when it is transferred from the transfer component to the loading point. At the same time, a universal ball joint and an elastic element are provided to cooperate. The universal ball joint and the board roll against each other, which greatly reduces the wear on the board. The elastic element provides a buffering force to avoid hard contact when the universal ball joint collides with the offset board, thus improving safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A board mounting device for SMT assembly, characterized in that it comprises:

[0007] The conveying assembly includes a frame on which at least one first conveyor belt is mounted. Correction components are installed on both sides of the first conveyor belt near the transfer assembly to adjust the position of the material plate when it is transferred from the transfer assembly to the loading point.

[0008] The transfer component is installed at the loading point of the conveyor component and includes a base. A second conveyor belt is installed on the base, and a lifting mechanism is installed on one side of the transfer component. The lifting mechanism is fixedly connected to the base and drives the second conveyor belt to move in the vertical direction.

[0009] Preferably, the correction assembly includes a pair of pillars spaced apart on the support, wherein a pair of spaced-apart support arms are rotatably connected to one pillar, and a carrier is rotatably connected to the other pillar. The end of the carrier is positioned within the gap between the two support arms, and positioning posts are provided at the top and bottom of the carrier, respectively, and are rotatably connected to the two support arms. A connecting plate is installed at the end of the carrier along the transport direction parallel to the first conveyor belt, and a plurality of elastic contacts are installed on the connecting plate along the transport direction perpendicular to the first conveyor belt.

[0010] Preferably, the elastic contact includes a housing mounted on a connecting plate, and a universal ball joint is elastically connected inside the housing. The ball part of the universal ball joint makes rolling contact with the feeding plate of the first conveyor belt. Specifically, the housing has a cavity, and an elastic element is installed at the bottom of the cavity. The telescopic end of the elastic element is rotatably connected to the bottom of the universal ball joint.

[0011] Preferably, the cavity has an internal thread, and an annular component is threaded into the cavity. The end of the universal ball joint extends toward the cavity to form a support rod. The support rod passes through the annular component and is rotatably connected to the elastic component at the bottom of the cavity. A slot is formed on one end face of the annular component near the bottom of the cavity. Correspondingly, the outer contour of the support rod extends outward to form a snap-fit ​​block that matches the slot.

[0012] Preferably, the elastic element can be a spring plunger, and a rotatable joint is installed at the bottom of the universal ball head, with the telescopic end of the spring plunger connected to the rotatable joint.

[0013] Preferably, there are two or more first conveyor belts installed on the frame, and the multiple first conveyor belts are installed on the frame at intervals in a vertical direction.

[0014] Preferably, a limit frame is also installed on the second conveyor belt. Specifically, the two ends of the limit frame are respectively installed on both sides of the second conveyor belt, and the limit frame is equipped with a top plate.

[0015] This utility model provides a board mounting device for SMT (Surface Mount Technology) component placement. It has the following advantages:

[0016] By installing a correction component on the first conveyor belt, the position of the material plate when it is transferred from the transfer component to the loading point can be adjusted. At the same time, a universal ball joint and an elastic element are installed to cooperate. The rolling friction between the universal ball joint and the material plate greatly reduces the wear on the material plate. The elastic element provides a buffering force to avoid hard contact when the universal ball joint collides with the offset material plate, thus improving safety. Attached Figure Description

[0025] 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 embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See attached document Figure 1-3 A board mounting device for SMT assembly includes a conveying assembly 1 for conveying the board to the processing position.

[0027] Transfer component 2 is installed at the loading point of conveying component 1. It can be considered as the initial position of the material plate in conveying component 1, and is used to transfer the material plate to conveying component 1.

[0028] The conveying assembly 1 includes a frame on which at least one first conveyor belt 11 is mounted. It is understood that in this application, "conveyor belt" refers to a complete transmission mechanism, not simply a belt. The transmission mechanism can be based on existing technology, and its working principle will not be elaborated upon here. Correction components 3 are installed on both sides of the first conveyor belt 11 near the transfer assembly 2 to adjust the position of the material plate when it is transferred from the transfer assembly 2 to the loading point.

[0029] In some embodiments, there are two or more first conveyor belts 11 mounted on the frame, and the multiple first conveyor belts 11 are mounted on the frame at intervals in a vertical direction.

[0030] The transfer component 2 includes a base on which a second conveyor belt 21 is mounted. A lifting mechanism 22 is mounted on one side of the transfer component 2 and is fixedly connected to the base. The lifting mechanism 22 drives the second conveyor belt 21 to move vertically, which can adapt to the first conveyor belts 11 at different heights. It can also sequentially transfer material plates to each of two or more first conveyor belts 11, thereby improving production efficiency and having strong compatibility.

[0031] The second conveyor belt 21 is also equipped with a limit frame. Specifically, the two ends of the limit frame are respectively installed on both sides of the second conveyor belt 21. The limit frame is equipped with a top plate to limit the height of the stacked material plates on the second conveyor belt 21 and prevent the material plates from tipping over after being stacked too high.

[0032] The lifting mechanism 22 can be selected from combinations such as lead screws, guide rods and drive motors, or from lifting structures available on the market that meet the operational requirements.

[0033] The correction assembly 3 includes a pair of support columns 31 spaced apart on the bracket. One support column 31 is rotatably connected to a pair of spaced-apart support arms, and the other support column 31 is rotatably connected to a bearing member 32. The end of the bearing member 32 is located within the gap between the two support arms, and the top and bottom ends of the bearing member 32 are provided with positioning posts, which are rotatably connected to the two support arms respectively. It can be understood that the rotatable connection between the support arms and the support column 31, as well as the rotatable connection between the positioning posts on the bearing member 32 and the support arms, can both be achieved using bearing parts or existing conventional technologies, and no restrictions are imposed here.

[0034] A connecting plate is installed at the end of the carrier 32 along the transport direction parallel to the first conveyor belt 11. Several elastic contacts 33 are installed on the connecting plate along the transport direction perpendicular to the first conveyor belt 11. (The specific number of elastic contacts 33 and the spacing between them can be selected according to the stacking height of the material plates). Each elastic contact 33 includes a housing 331 mounted on the connecting plate. A universal ball joint 332 is elastically connected inside the housing 331. The ball portion of the universal ball joint 332 rolls in contact with the material plate on the first conveyor belt 11. Specifically, the housing 331 has a cavity. The bottom of the body is equipped with an elastic element 333, and the telescopic end of the elastic element 333 is rotatably connected to the bottom of the universal ball head 332. It can be understood that when the material plate is transferred to the first conveyor belt 11 and its position is offset, the universal ball head 332 rolls and contacts the material plate and is squeezed and contracted. At this time, the offset material plate is gradually corrected by the resistance of the elastic contact 33, so as to avoid the material plate from colliding with the frame. It can be understood that the compression limit of the elastic element 333 and the degree of exposure of the universal ball head 332 should ensure that the universal ball head 332 can still adjust the offset material plate located on the first conveyor belt 11 under the compression limit state.

[0035] In some embodiments, the cavity has an internal thread, and an annular member 334 is threadedly connected within the cavity. The end of the universal ball joint 332 extends toward the cavity to form a support rod. The support rod passes through the annular member 334 and is rotatably connected to the elastic member 333 at the bottom of the cavity. It is understood that the support rod can slide within the annular member 334. A slot is formed on one end face of the annular member 334 near the bottom of the cavity. Correspondingly, the outer contour of the support rod extends outward to form a locking block that matches the slot. When the support rod rotates, the annular member 334 is moved toward the bottom or top of the cavity through the cooperation of the slot and the locking block, thereby simultaneously adjusting the exposure degree and compression stroke of the universal ball joint 332. This adjustment method ensures that the more exposed the universal ball joint 332 is, the greater the compression stroke, and conversely, the more retracted the universal ball joint 332 is, the smaller the compression stroke, resulting in better compatibility.

[0036] The elastic element 333 can be a spring plunger. In addition, the bottom of the universal ball head 332 is rotatably connected to the telescopic end of the elastic element 333. Specifically, the bottom of the universal ball head 332 is equipped with a rotatable joint, and the telescopic end of the spring plunger is connected to the rotatable joint, ensuring a stable connection between the two while facilitating convenient and unobstructed rotational adjustment.

[0037] In addition, workers can adjust the exposure of the universal joint without affecting the compression stroke of the universal ball joint 332 by adjusting the distance between the two support pillars 31.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
