Description

Pick-up unit

[technical field]

The utility model relates to a kind of measuring equipment, and particularly relevant for a kind of pick-up unit that measures flatness.

[background technology]

In recent years, along with advancing by leaps and bounds of computing machine science and technology, the running speed of computing machine is also constantly accelerated, so the heating power of main frame internal electronic element is also constantly soaring.For the electronic component that prevents main frame inside produces temporary or inefficacy permanently because of overheated, the heat dissipation of electronic component becomes extremely important.With regard to prior art,, install radiator fan additional in the casing inside of main frame and dispelled the heat with the form that thermal convection is provided in order effectively to reduce the heat energy that is produced when electronic component operates.In addition, more can be directly at power supply unit, CPU (central processing unit) (the central processing unit of main frame, CPU) and graphics processing unit (graphic processing unit, GPU), or even install radiator fan and heat radiator (heat spreader) additional on the easy electronic component that raises of chipset equitemperature, so that promptly remove the heat energy that these electronic components are produced when running.

With regard to CPU (central processing unit); because the influence of manufacturing accuracy makes between heat radiator and the CPU (central processing unit) and can't fit fully; therefore between heat radiator and CPU (central processing unit), can dispose a hot pad usually, to improve the heat conduction efficiency between heat radiator and the CPU (central processing unit).Yet the resistance value of hot pad is directly proportional with its thickness.In other words, if use thin hot pad, then for the requirement also just relative raising of heat radiator with the flatness of CPU (central processing unit).The instrument that measures flatness at present for example is three-dimensional amount bed or laser interferometer, and these measuring instruments are bulky mostly and price is not striking.

[summary of the invention]

The purpose of this utility model is to provide a kind of pick-up unit exactly, can measure the flatness of determinand easily.

For reaching above-mentioned purpose, the utility model proposes a kind of pick-up unit, it is suitable for detecting one to be measured flatness of a determinand.This pick-up unit comprises that a platform, a bracing frame, a sleeve, one first rod member, a roller, one second rod member, one the 3rd rod member, a plotting sheet and paint pen, and wherein platform is suitable for carrying determinand, and bracing frame then is disposed on the platform.Sleeve is for being disposed on the bracing frame slidably, and sleeve and platform surface are orthogonal, and the mobile route of sleeve is parallel with platform surface.In addition, first rod member is arranged among the sleeve, and roller is hubbed at an end of first rod member, and the other end of first rod member then is pivoted to an end of second rod member.One end of the 3rd rod member is for being disposed on the bracing frame slidably, and the other end of the 3rd rod member is pivoted between the two ends of second rod member, and the mobile route of the 3rd rod member is parallel with platform surface.In addition, plotting sheet is disposed on the platform, and paints the other end that pen is disposed at second rod member.When roller contacts with to be measured, and sleeve is when driving first rod member and moving, and first rod member can drive second rod member, draws to be measured profile so that paint pen on plotting sheet.

In addition, above-mentioned pick-up unit more comprises a push rod, and this push rod is connected to sleeve, and is suitable for driving sleeve and moves.

Compared to prior art, the utility model just can be drawn to be measured profile because of adopting simple linkage assembly on plotting sheet, and therefore not only cost is lower for pick-up unit of the present utility model, and processing ease.

[embodiment]

Please refer to Fig. 1, pick-up unit 100 is suitable for detecting to be measured 212 flatness of a determinand 200.This pick-up unit 100 comprise a platform 110, a bracing frame 120, a sleeve 130, one first rod member 140, a roller 150, one second rod member 142, one the 3rd rod member 144, a plotting sheet 160 and paint the pen 170, wherein platform 110 is in order to carrying determinand 200, and bracing frame 120 is disposed on the platform 110.Sleeve 130 is for being disposed at slidably on the bracing frame 120, and sleeve 130 is orthogonal with the surface 112 of platform 110.In addition, the mobile route of sleeve 130 is parallel with platform surface 112, and first rod member 140 is to be arranged among the sleeve 130.In other words, sleeve 130 is suitable for driving first rod member 140 and moves along the direction that is parallel to platform surface 112, and first rod member 140 is suitable for moving perpendicular to the direction of platform surface 112.

Roller 150 is hubbed at an end of first rod member 140, and in order to increase the serviceable life of roller 150, the material of roller 150 for example is metal, plastics or other wear-resisting material.In addition, the other end of first rod member 140 is pivoted to an end of second rod member 142, and paints the other end that pen 170 is disposed at second rod member 142.In addition, plotting sheet 160 is disposed on the platform 110, and paints pen 170 and contact with plotting sheet 160.Moreover an end of the 3rd rod member 144 is disposed on the bracing frame 120 slidably, and the other end of the 3rd rod member 144 is pivoted between the two ends of second rod member 142.What deserves to be mentioned is that for the ease of promoting sleeve 130, this pick-up unit 100 comprises that more one is connected to the push rod 180 of sleeve 130.And relevant for the operating process of pick-up unit 100 will describe in detail as after.

Please also refer to Fig. 1 and Fig. 2, the operating process of pick-up unit 100 comprises the following steps.At first, on determinand 200, cook up route ab to be measured, cd, ef, gh and ij, then determinand 200 is placed on the platform 110, and roller 150 is seated on to be measured 212 of determinand 200, and aim at route ab to be measured.Then, promote push rod 180, so that roller 150 moves to the b end by to be measured 212 a end, and the mode that promotes push rod 180 for example is artificial or robotic arm.When roller 150 passes through to be measured 212 uneven part, roller 150 will drive first rod member 140 and move up and down.At this moment, first rod member 140 is a fulcrum with the 3rd rod member 144, therefore paints pen 170 and draw the profile kl of the representative of route ab to be measured on plotting sheet 160.

After the profile kl of the representative of route ab to be measured has been drawn on the plotting sheet 160, mobile determinand 200, so that roller 150 is aimed at route cd to be measured, and the method for mobile determinand 200 for example is artificial or robotic arm.So repeat above-mentioned step till to be measured 212 profile all being treated profile section cd, ef, gh and ij representative all is drawn on the plotting sheet 160.Whether the measurement personnel just can meet the requirements so that judge to be measured 212 flatness according to the profile of plotting sheet 160 demonstrations.What deserves to be mentioned is that plotting sheet 160 also can adopt the scroll bar kenel, so that to be measured 212 profile is drawn thereon.In addition, plotting sheet 160 is adjustable height also, so that the different profiles for the treatment of profile section of record.

In sum, the simple linkage assembly of pick-up unit utilization of the present utility model just can detect the flatness of determinand, and therefore not only cost is lower for pick-up unit of the present utility model, and processing ease.In addition, via the position of the pivoting point that changes second rod member and the 3rd rod member, and collocation selects the diameter of roller just can adjust the accuracy of detection of pick-up unit of the present utility model.
