Description

Technical Field

[0001] This utility model relates to the field of screw machine technology, and in particular to a screw-locking presser foot structure. Background Technology

[0002] A screw fastener is a small, automated machine that fastens screws. Its electric screwdriver is responsible for picking up and fastening the screws. The invention of screw fasteners has both improved work efficiency and reduced the intensity of manual labor.

[0003] In related technologies, screw machines are used to fasten and connect the PCB board or cover of LED modules. However, PCB boards often warp, and covers may not be properly closed or may protrude. These problems shorten the safe distance between the screw machine's jaws and the LED beads. During screw fastening, abnormalities such as screw misalignment, floating, or sinking can easily occur, leading to LED collisions and flashing, and increasing the defect rate. These defects are often discovered in subsequent operations, such as during potting or aging, which undoubtedly increases maintenance costs.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this utility model, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a screw fastening foot structure, which at least to some extent overcomes the problems of screw misalignment, floating, and sinking during PCB board fastening due to PCB board tilting, inadequate masking, or protrusion in the PCB board fastening process of related technologies.

[0006] Other features and advantages of this invention will become apparent from the following detailed description, or may be learned in part by practice of this disclosure.

[0007] According to one aspect of the present invention, a screw-locking pressure foot structure is provided for locking screws on an LED light board. The screw-locking pressure foot structure includes a body and a connector connected to a screw-locking machine. The connector is connected to the top of the body. The bottom of the body is provided with a flat pressing surface. A through hole for the screw to pass through is provided on the pressing surface. The through hole is square and can accommodate multiple LED beads.

[0008] According to one embodiment of the present invention, a protective pad is provided on the pressing surface, and a connecting hole matching the through hole is provided on the protective pad.

[0009] According to one embodiment of the present invention, the main body includes a frame structure, a pair of connecting arms and a pair of connecting rods. The connecting member is connected to the top surface of the frame structure, the connecting arm is connected to the bottom surface of the frame structure, and the two ends of the connecting rod are respectively connected to the bottom of the pair of connecting arms.

[0010] According to one embodiment of the present invention, the four-sided space formed by the connection of a pair of connecting arms and a pair of connecting rods is the through hole; the bottom surfaces of the pair of connecting arms and the bottom surfaces of the pair of connecting rods are connected to form the pressing surface.

[0011] According to one embodiment of the present invention, the frame structure has a movable channel for the screwdriver bit to move, and the movable channel is connected to the through hole.

[0012] According to one embodiment of the present invention, an avoidance opening is provided on the inner wall of the active channel.

[0028] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0029] refer to Figures 1 to 4 This embodiment provides a screw-locking pressure foot structure, which is used to be assembled on a screw machine 10 to lock the screws of the LED light board. The screw-locking pressure foot structure includes a body 30 and a connector 20.

[0030] The connector 20 is a vertical rod whose extension direction is parallel to the axis of the through hole 36. A hollowed-out long groove is provided in the middle of the connector 20 for assembly and fixation with the screw machine 10, and its bottom end is fixedly connected to the top surface of the body 30. The connector 20 can be integrally formed with the body 30.

[0031] The main body 30 includes a frame structure 31, a pair of connecting arms 34, and a pair of connecting rods 35, all integrally formed. The bottom surface of the frame structure 31 is connected to the top surface of the pair of connecting arms 34, which are respectively located on two opposite sides of the frame structure 31. A pair of connecting rods 35 are connected between the bottom surfaces of the pair of connecting arms 34, with each connecting rod 35 located at one end of the bottom of the connecting arm 34. The four-sided space formed by the connection of the pair of connecting arms 34 and the pair of connecting rods 35 is a through hole 36, the axis of which is perpendicular to the plane of the PCB board (not shown). The bottom surfaces of the pair of connecting arms 34 and the pair of connecting rods 35 are connected to form a pressing surface 37, which is flat and parallel to the plane of the PCB board (not shown).

[0032] The frame structure 31 has a movable channel 32 for the screwdriver bit of the screwdriver 10 to move through, and the movable channel 32 communicates with the through hole 36. The screwdriver bit of the screwdriver 10 can pass through the movable channel 32 and is partially assembled between a pair of connecting arms 34. The inner wall of the movable channel 32 is provided with a relief opening 33, which can avoid the protruding part of the screwdriver bit of the screwdriver 10. The inner wall of the relief opening 33 has an inclined surface, which can be used to guide the screwdriver 10 into the movable channel 32.

[0033] A through-hole 36 is provided on the pressure surface 37, and the diameter of the through-hole 36 is smaller than the diameter of the movable channel 32. The screws on the screwdriver bit 10 can pass through the through-hole 36 and be fastened to the designated position on the PCB board. The through-hole 36 is a square hole that can accommodate multiple LEDs (not shown in the figure), which increases the contact area between the pressure surface 37 and the PCB board or the faceplate. This shape can better match the arrangement of multiple LEDs on the PCB board (most LEDs on PCB boards are arranged in an array), ensuring a flat pressing effect.

[0034] When the screw machine 10 is fastening, as it descends along the Z-axis (equivalent to the axis of the through hole 36), the screw fastening foot structure moves along the Z-axis with the screw machine 10 and abuts against the PCB board or mask, ensuring that the mask fits the light board before fastening. This effectively reduces abnormalities such as screw misalignment, floating, or sinking caused by PCB warping or mask not being pressed into place, thus effectively improving quality.

[0035] The distance between the top ends of a pair of connecting arms 34 is greater than the distance between their bottom ends. That is, the pair of connecting arms 34 extend downward from the bottom surface of the frame structure 31 and narrow inward. The width of the bottom surface of the connecting arm 34 is greater than the width of the bottom surface of the connecting rod 35, which can ensure the overall strength of the bottom of the connecting arm 34 and the body 30, improve the pressing effect of the presser foot, and greatly reduce the phenomenon of hitting or shining lights caused by PCB board warping or mask cover not being in place or protrusion.

[0036] A protective pad 38 is provided at the bottom of the main body 30. The protective pad 38 is connected to the pressure surface 37, and the protective pad 38 has a connecting hole 39 that matches the through hole 36. The connecting hole 39 is connected to the through hole 36. The protective pad 38 can be a rubber gasket, which can protect the lamp surface and increase the contact area with the lamp surface.

[0037] Of course, upon careful consideration of the foregoing description of the representative embodiments, those skilled in the art will readily understand that various modifications, additions, substitutions, deletions, and other changes can be made to these specific embodiments within the scope of the principles of this disclosure. Therefore, the foregoing detailed description should be clearly understood as being given by way of illustration and example only, and the spirit and scope of this disclosure are limited only by the appended claims and their equivalents.
