Description

Technical Field

[0001] This utility model relates to the field of SMT placement positioning equipment, specifically a SMT placement positioning structure for PCBA production. Background Technology

[0002] SMT (Surface Mount Technology) is an essential piece of equipment in the manufacturing of electronic products. Although existing equipment can clamp and fix the components during SMT placement, it is not possible to readjust the height after clamping and fixing. In addition, it is not convenient to quickly separate and remove the components after placement.

[0003] According to a patent document with publication number CN220915665U, a SMT placement positioning structure for PCBA processing includes an SMT placement fixture assembly. A positioning and clamping component is disposed on the upper surface of the SMT placement fixture assembly. The positioning and clamping component includes a clamping mechanism disposed on the upper surface of the SMT placement fixture assembly, and a fume collection mechanism is disposed on one side of the clamping mechanism. The clamping mechanism positions and clamps the SMT components, and the fume collection mechanism absorbs fumes during SMT placement processing. This technology... In use, the design utilizes an SMT placement fixture assembly, a clamping mechanism, and a fume collection mechanism. This allows for the placement of the SMT component on the upper surfaces of two sets of clamping blocks. Activating an electric telescopic rod moves a moving block, which in turn moves a connecting rod. The connecting rod then moves an extension rod, which in turn pushes the two sets of clamping blocks towards both sides of the SMT component, thus positioning it. However, while this design achieves the clamping of the component, it cannot simultaneously move it vertically, causing inconvenience during use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an SMT placement positioning structure for PCBA production, so as to solve the problems mentioned in the background technology. The present utility model has a novel structure. In use, the pad is installed on the inner wall of the movable plate. The right-angle seat moves inward to clamp the pad. Later, the lifting mechanism pushes the pad and the movable plate upward at the same time to adjust the pad placement operation height.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an SMT placement positioning structure for PCBA production, comprising a base, a fixed seat welded onto the base, a collection box movably mounted between the fixed seats, a limit block fixed to the bottom of the collection box, a limit groove on the base, the limit block movably mounted inside the limit groove, a pushing mechanism fixedly mounted on the side of the fixed seat, a right-angle seat mounted on the pushing mechanism, a groove on the right-angle seat, and a fixing tube fixed inside the groove.

[0006] Furthermore, the fixed tube has an installation hole inside, and a movable column is movably installed inside the installation hole. The movable column is installed inside the fixed tube through a reset mechanism.

[0007] Furthermore, a support plate is fixed on the base, a mounting base is fixed at one end of the support plate, and a motor housing is fixed on the mounting base.

[0008] Furthermore, a heat dissipation assembly is fixedly installed inside the motor housing. The heat dissipation assembly includes an exhaust fan, which is mounted inside the motor housing via a mounting bracket.

[0009] Furthermore, a cavity is formed between the mounting base and the motor housing, and a fixing rod is fixed inside the cavity, with a lighting mechanism fixed between the fixing rods.

[0010] Furthermore, a groove is formed on the inner wall of the right-angle seat, a support mechanism is fixed inside the groove, a slider is fixed at one end of the support mechanism, and a movable plate is fixed at one end of the slider.

[0011] Furthermore, a fixing groove is provided on the right-angle base, and a lifting mechanism is fixed inside the fixing groove. A fixing plate is fixed to one end of the lifting mechanism.

[0012] Furthermore, the fixing tube is fixed inside the groove by a fixing block, and a silicone block is fixed to one end of the movable column.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, the patch is installed on the inner wall of the movable plate during use. The right-angle seat moves inward to clamp the patch. Later, the lifting mechanism pushes the patch and the movable plate upward at the same time to adjust the operating height of the patch.

[0015] 2. In this utility model, the collection box is installed at the bottom of the right-angle base. The collection box collects electronic components that fall during the surface mount operation. In addition, the collection box provides limiting support for the right-angle base, so that the right-angle base can maintain horizontal clamping and movement.

[0016] 3. In this utility model, the exhaust fan blows air downwards, which provides rapid drying during the mounting process. In addition, the downward blowing of the exhaust fan can dissipate heat from the lighting mechanism, ensuring that the lighting mechanism can work for a long time at room temperature.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5This utility model provides a technical solution: an SMT placement positioning structure for PCBA production, including a base 1, a fixed seat 4 welded onto the base 1, a collection box 3 movably mounted between the fixed seats 4, a limit block 19 fixed to the bottom of the collection box 3, a limit groove 2 opened on the base 1, the limit block 19 movably mounted inside the limit groove 2, a pushing mechanism 5 fixedly mounted on the side of the fixed seat 4, the pushing mechanism 5 being a linear reciprocating electric push rod, the pushing mechanism 5 pushing a right-angle seat 10 inward to complete the clamping and fixing of the workpiece, the right-angle seat 10 being mounted on the pushing mechanism 5, and so on. The right-angle base 10 has a groove 11, and a fixing tube 12 is fixed inside the groove 11. The fixing tube 12 has a mounting hole inside, and a movable column 14 is movably installed inside the mounting hole. The movable column 14 is installed inside the fixing tube 12 through a reset mechanism 24, which is a reset spring. When the workpiece is installed, the movable column 14 is pressed first, and the movable column 14 retracts inside the fixing tube 12. Later, when the right-angle base 10 loses its grip on the workpiece, the movable column 14 pushes the workpiece to move slowly upward, so that the height of the workpiece is higher than the top of the right-angle base 10, which facilitates the removal of the workpiece later.

[0025] In this embodiment, a support plate 6 is fixed on the base 1, and a mounting base 7 is fixed to one end of the support plate 6. A motor housing 8 is fixed on the mounting base 7. A heat dissipation assembly 9 is fixedly installed inside the motor housing 8. The heat dissipation assembly 9 includes an exhaust fan 25, which is installed inside the motor housing 8 via a mounting bracket. A cavity 26 is formed between the mounting base 7 and the motor housing 8. A fixing rod 28 is fixed inside the cavity 26. A lighting mechanism 27 is fixed between the fixing rods 28. The lighting mechanism 27 is a lamp that illuminates the bottom fixing base 4, facilitating the operator's later operation of the workpiece inside the right-angle base 10.

[0026] In this embodiment, a groove 21 is formed on the inner wall of the right-angle seat 10. A support mechanism 22 is fixed inside the groove 21. A slider 23 is fixed to one end of the support mechanism 22. A movable plate 15 is fixed to one end of the slider 23. A fixing groove 16 is formed on the right-angle seat 10. A lifting mechanism 17 is fixed inside the fixing groove 16. The lifting mechanism 17 is a linear reciprocating electric push rod. The lifting mechanism 17 pushes the workpiece up and down to adjust its operating height through the fixing plate 18. A fixing plate 18 is fixed to one end of the lifting mechanism 17. The fixing tube 12 is fixed inside the groove 11 through the fixing block 13. A silicone block is fixed to one end of the movable column 14. The support mechanism 22 is a support spring. Under the push of the support spring, the slider 23 pushes the movable plate 15 to move continuously, which facilitates the later return of the movable plate 15 to its original position.

[0027] In use, the workpiece is first installed on the right-angle seat 10, and placed on top of the movable column 14. By pressing the workpiece, the workpiece and the movable column 14 move downwards, and the movable column 14 retracts into the fixed tube 12. After the workpiece descends, the pushing mechanism 5 is activated to push the right-angle seat 10 inwards. After the right-angle seat 10 moves inwards, the movable plate 15 clamps and limits the workpiece on both sides. Under the clamping and limiting condition, the lifting mechanism 17 pushes the fixed plate 18 upwards. The fixed plate 18 pushes the workpiece and the movable plate 15 upwards. When the movable plate 15 moves upwards, the slider 23 presses against the support mechanism 22. After the workpiece moves upwards, the movable column 14 loses its squeezing force and is pushed by the reset mechanism 24. The movable column 14 rises with the workpiece, providing multi-point support for the workpiece at multiple locations. After the workpiece is raised, the operator can operate it. During operation, the lighting mechanism 27 provides a bright working environment, and the exhaust fan 25 blows air downwards to quickly dry the surface mount mechanism after operation. The exhaust fan 25 also cools the lighting mechanism 27. If electronic components are accidentally dropped during operation, they are collected by the collection box 3. After operation, the right-angle seat 10 moves outwards, and the reset mechanism 24 pushes the workpiece to rise slowly to complete the material removal. A friction ring pad is installed between the movable column 14 and the fixed tube 12, which causes the movable column 14 to move slowly in the later stages.
