Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a heat sink riveting testing device. Background Technology

[0002] With the rapid development of electronic devices towards higher integration and higher power density, heat dissipation performance has become one of the core factors affecting the operational stability and lifespan of equipment. As a key component for efficient heat conduction and dissipation, the structural integrity and assembly precision of the heat sink directly determine the overall efficiency of the heat dissipation system. In the manufacturing process of heat sinks, the riveting process is the core step in ensuring a stable connection between the heat sink body and components such as fins and substrates. The connection strength, perpendicularity, displacement, and the presence of defects such as missing or loose riveting at the riveting points all have a decisive impact on the integrity of the heat conduction path and the structural reliability of the heat sink. Therefore, accurate inspection of the riveting quality of heat sinks has become an indispensable and crucial link in the production process.

[0003] Currently, the industry mainly uses two methods to inspect the quality of heat sink riveting: manual inspection and traditional equipment inspection. Manual inspection relies on operators to conduct spot checks by visual observation, touch, or with the help of simple measuring tools (such as calipers and plug gauges). This method is not only greatly affected by subjective factors such as operator experience and fatigue, but also suffers from inconsistent inspection standards and a high rate of missed and false inspections. In addition, manual inspection is extremely inefficient and cannot meet the current needs of large-scale, batch production of heat sinks, severely restricting the overall capacity improvement of the production line.

[0004] Existing traditional testing equipment mostly employs single mechanical contact testing or optical imaging testing methods, which suffer from significant drawbacks such as limited functionality and poor adaptability. Furthermore, most current testing equipment lacks the ability to automatically integrate with production lines, requiring manual transfer of heat sinks from the production line to the testing equipment, followed by manual return after testing. This not only increases manual operation steps and extends the production cycle but also risks damage to the heat sinks due to manual handling. Therefore, developing a heat sink riveting testing device that can achieve automated testing, high accuracy, comprehensive functions, and integration with production lines has become an urgent need to address current industry pain points and improve the quality and efficiency of heat sink production.

[0005] The purpose of this utility model is to provide a heat sink riveting inspection device with a simple and reasonable structural design, stable and reliable operation; it can automatically feed and transport the workpiece to the inspection area, and automatically unload it after inspection; it is convenient to use and has high inspection efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A heat sink riveting inspection device includes a frame, a feeding assembly, a discharging assembly, a workpiece gripping assembly, an inspection feeding and unloading assembly, an inspection module, and a workpiece limiting seat;

[0008] The frame is vertically arranged, with a horizontal worktable on top and several feet and casters at the bottom; a protective cover is provided on the outer edge of the worktable.

[0009] The feeding assembly, the detection feeding / unloading assembly, and the unloading assembly are horizontally positioned on the worktable.

The workpiece limiting seat is positioned above the detection feeding / unloading assembly. The detection module is positioned directly above the detection feeding / unloading assembly.

[0010] The loading and unloading components are used to transport workpieces and are conventional conveying components, each including a conveyor motor, a drive roller, a driven roller, and a conveyor belt. The conveyor motor is connected to the drive roller and drives it to rotate. A driven roller is located on the opposite side of the drive roller, and the left and right ends of the conveyor belt are respectively fitted onto the drive roller and the driven roller. The loading and unloading components are existing technology and will not be described in detail here.

[0011] The workpiece gripping assembly includes a linear module, a connecting plate, a lifting cylinder, a suction cup mounting plate, a suction cup bracket, and a vacuum suction cup.

[0012] The linear module includes a slide table, which is a component that provides power for the left and right lateral movement of the slide table. It is a mechanical transmission device that combines linear motion with automated control. It is an existing technology and common device, mainly composed of a lead screw, linear guide rail, aluminum alloy profile, lead screw support, coupling, motor, photoelectric switch, slide table, etc. The slide table has a threaded through hole, which is sleeved on the lead screw. The motor drives the lead screw to rotate, thereby driving the slide table to slide along the lead screw. The lead screw is set horizontally, that is, the slide table can move horizontally left and right.

[0013] The connecting plate is vertically arranged and fixed to the front side of the slide table; the lifting cylinder is vertically arranged and fixed to the front side of the connecting plate, and its output shaft is connected to the horizontally arranged suction cup mounting plate; the suction cup mounting plate is provided with several vertically arranged suction cup brackets; the bottom of the suction cup brackets is provided with vacuum suction cups.

[0014] The detection feed and unfeed assembly is a linear module two, including a slide table two; the linear module two has the same structure as the linear module and is a component that drives the slide table two to move back and forth.

The lenses of the 2D defect detection camera and the 3D line laser scanning camera are perpendicularly aligned with the material feeding and unloading assembly.

[0017] The workbench is equipped with several operation buttons and a vertically mounted display screen.

[0018] Preferably, the workpiece limiting cavity is provided with air guide holes at the corners, so that when the workpiece is put in and taken out, an air pressure difference is formed inside and outside the workpiece limiting cavity to avoid assembly jamming. If the workpiece and the insertion cavity are "tightly fitted", the air in the cavity is easily compressed when inserted, forming "air resistance", making it difficult for the workpiece to be inserted into place. At this time, the air guide holes can be used as exhaust channels, and compressed air is discharged from the air guide holes to avoid assembly obstruction and jamming caused by air resistance.
