Description

Technical Field

[0001] The present invention relates to the technical field of component measurement and detection, and in particular to a component plane detection device for a graphics card fan and a control method thereof. Background Art

[0002] The main purpose of the graphics card fan is to increase the air flow speed to achieve the purpose of heat dissipation. The graphics card fan rotates to make the air flow flow, and the flowing air flow accelerates to take away the heat on the heat sink, thereby helping the graphics card to dissipate heat. During the production process of the graphics card fan, various components including the heat sink will be inspected in the plane, and the inspection and measurement will be carried out through the inspection device during the inspection process;

[0003] The existing flatness detection method is to place a knife-edge ruler on the surface to be tested, and then use a standard flat feeler gauge to test the gap between the flat surface and the knife-edge ruler to determine whether it is qualified. However, this method requires high worker skills and requires a lot of manpower, resulting in high costs and limiting the efficiency of heat sink flatness detection;

[0004] In view of the above technical problems, a heat sink flatness detector is disclosed in the announcement number CN107843217A. By using a flatness detector to detect the flatness of the plane structure of the heat sink, the efficiency of automatic detection is achieved, which reduces the human participation in the detection process, thereby reducing the labor intensity and detection cost of the workers. At the same time, the flatness detector is used to effectively reduce the difficulty of flatness detection, reduce the requirements for the work experience of the staff, and further reduce the labor cost. In addition, the flatness detector is used to avoid the use of standard flat feeler gauges and knife-edge gauges, shorten the time required for detection, and improve the detection efficiency.

[0005] The above patent also has the following shortcomings: during the inspection process, the parts are not inspected on only one of the surfaces. Inspecting only one surface during the inspection process will cause inaccurate overall inspection data. At the same time, the surface and direction to be inspected need to be manually adjusted each time the inspection is performed. After the adjustment, the position of the parts will be shifted, reducing the accuracy of the inspection. Summary of the invention

[0006] The object of the present invention is to provide a component plane detection device for a graphics card fan and a control method thereof, which has the ability to complete bidirectional mobile detection in a progressive manner, thereby measuring and detecting different positions of the detection surface, and can also realize detection in the rotation direction to improve the accuracy and effect of the detection, and can also realize the effect of flipping the component, so as to detect the bottom surface.

[0020] Exemplarily, a slot is formed on the top of the box body, and the support is located inside the slot.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The present invention provides a component plane detection device for a graphics card fan and a control method thereof, comprising a box 1:

[0046] A material moving mechanism 2 for adjusting the detection orientation is provided at the bottom of the inner cavity of the box body 1, a flipping mechanism 5 for clamping and turning the material is provided at one end of the bottom of the inner cavity of the box body 1, a detection mechanism 3 for flatness detection is provided at the top of the outer side of the box body 1, and a clamping mechanism 4 for clamping and positioning is provided at one end of the top of the box body 1;

[0047] It is used to improve the measurement and detection of components in the graphics card fan, such as heat sinks, and can improve the comprehensiveness and accuracy of the detection process;

[0048] The material clamping mechanism 4 includes a pushing component, a transmission component and a sliding component. The pushing component is arranged at one end of the top of the box body 1, the transmission component is arranged at one side of the pushing component, and the sliding component is arranged at the center of the top of the box body 1.

[0049] It is used to clamp the material in place and also to move the parts to the middle for inspection.

[0050] The material moving mechanism 2 includes a displacement component and a power component. The displacement component is arranged at the bottom of the inner cavity of the box body 1, and the power component is arranged at the top of the inner cavity of the box body 1.

[0051] The direction and position of the inspection are adjusted by the material moving mechanism 2, the parts are turned over to different sides for inspection by the turning mechanism 5, and the materials are clamped and fixed before inspection by the clamping mechanism 4, and the parts are inspected by the inspection mechanism 3 at the same time.

[0052] It is used to realize feeding operation, and in the process of feeding material movement, it can also realize detection and measurement while moving slowly, and it can also stop moving for detection and measurement. Detection operations can be carried out based on the above two methods. In addition, the height position of the detected material can be adjusted by moving up and down during detection, and then the detection direction can be adjusted by rotating engagement, so as to better complete the detection and measurement operations.

[0053] Preferred:

[0054] like Figure 7 As shown, the first electric push rod 48 in the pushing assembly is fixedly mounted on one end of the top of the box body 1, and a push plate 49 is fixedly mounted on the output end of the first electric push rod 48, which is conducive to the power output operation during the clamping process and the release.

[0055] like Figure 7 As shown, the support rod 414 in the transmission assembly is rotatably connected to the top of the box body 1, and a third gear 413 is fixedly installed on the top of the support rod 414. The outer side of the third gear 413 is meshed with a toothed plate 410, and one side of the push plate 49 is fixed to the toothed plate 410;

[0056] A connecting rod 412 is fixedly mounted on the end of the tooth plate 410 , and a fixing plate 411 is slidably connected to the outer side of the connecting rod 412 .

[0057] The above-mentioned inferred pulling force can realize horizontal movement and complete the meshing transmission, so that the clamping plates 47 on both sides complete the mobile clamping work;

[0058] like Figure 7 As shown, the connection seat 41 in the sliding assembly is fixedly installed on the top of the box body 1, and a slide groove 42 is opened on the top of the connection seat 41. The inner cavity of the slide groove 42 is slidably connected with a slider 43, and a vertical plate 44 is fixedly installed on the top of the slider 43;

[0059] A telescopic rod 45 and a spring 46 are fixedly installed on the inner side of the vertical plate 44 . The spring 46 is located on the outer side of the telescopic rod 45 . A clamping plate 47 is fixedly installed on the inner ends of the telescopic rod 45 and the spring 46 . One end of the vertical plate 44 is fixed to one end of the fixed plate 411 .

[0060] It can realize the function of supporting sliding, and through the setting of the elastic member, it can not only ensure stable clamping and pushing of materials, but also protect the detected parts during the clamping process.

[0061] When clamping:

[0062] The state shown in the figure is an unclamped state. When the parts need to be clamped, the first electric push rod 48 works directly, and the first electric push rod 48 pushes the push plate 49 to drive the connected tooth plate 410 to move. Since two sets of tooth plates 410 are provided, and the push plate 49 is connected to the corresponding tooth plates 410 as shown in the figure, when one side of the tooth plate 410 moves, the third gear 413 is driven to rotate through the tooth meshing, and the third gear 413 will drive the other set of tooth plates 410 to move through the tooth meshing. During the movement of the two sets of tooth plates 410, the vertical plates 44 will be driven to slide horizontally through the fixed plate 411, and move inward synchronously and reduce the distance between the two sets of vertical plates 44;

[0063] During the movement, the vertical plate 44 drives the slider 43 to slide in the slide groove 42 provided in the connecting seat 41 to ensure the stability of the movement, and at the same time pushes the telescopic rod 45, the spring 46 and the clamping plate 47 to move synchronously until the clamping plate 47 contacts the parts and continues to move. Then, the telescopic rod 45 and the spring 46 will achieve a slight pressure due to the driving force, completing the operation of clamping and pushing the material.

[0064] Based on the above, while achieving the effect of clamping the material, the material can also be pushed to move, achieve alignment, and avoid offset, so as to assist the detection effect and accuracy. The elastic setting during the clamping process ensures the clamping state and effect while also realizing protection operations during the clamping process of the parts.

[0065] further:

[0066] like Figure 3 As shown, the first electric slide 21 in the displacement assembly is fixedly installed at the bottom of the inner cavity of the box body 1, the second electric slide 22 is fixedly installed on the top of the moving end of the first electric slide 21, and a connecting plate 23 is fixedly installed on one side of the moving end of the second electric slide 22.

[0067] It is used to realize horizontal movement when feeding materials and to realize meshing operation by adjusting the height, so as to adjust the detection direction by rotation;

[0068] like Figure 3 As shown, the support 24 in the power assembly is rotatably connected to the top of the connecting plate 23, a loading plate 26 is fixedly installed on the top of the support 24, and a second gear 25 is fixedly installed on the top of the outer side of the support 24;

[0069] A first motor 27 is fixedly mounted on the top of the inner cavity of the box body 1 . The output shaft of the first motor 27 is keyed to a first gear 28 , and the first gear 28 is meshed with the second gear 25 .

[0070] The rotation operation is completed through power output, and the above-mentioned technical effect is achieved by the meshing rotation method.

[0071] A slot hole 6 is formed on the top of the box body 1 , and the support column 24 is located inside the slot hole 6 .

[0072] The slots 6 are provided to accommodate the support pillars 24 to ensure stable horizontal movement.

[0073] The components are directly placed on the top of the loading plate 26, and the components are larger than the loading plate 26. Then the first electric slide 21 drives the components above and the components to be tested to move horizontally together, and then move to the desired position, and the final position is the state shown in the figure;

[0074] When it is necessary to rotate and adjust the orientation, first drive the connecting plate 23 and the pillar 24 to move downward together through the second electric slide 22. At this time, the pillar 24 will directly pull the second gear 25 and the loading plate 26 to move downward together until the second gear 25 and the first gear 28 are engaged. Finally, the first motor 27 can be operated to drive the first gear 28 to rotate. After that, the first gear 28 will also drive the loading plate 26 and the top parts to rotate together through the second gear 25 through the meshing connection relationship. When it is rotated to the desired position, it can be moved up again and then clamped and fixed, then released, and finally moved for detection.

[0075] Going further:

[0076] like Figure 2 As shown, the bracket 31 in the detection mechanism 3 is fixedly installed on the top of the outer side of the box body 1, the top of the bracket 31 is fixedly installed with a third electric slide 32, the bottom of the moving end of the third electric slide 32 is fixedly installed with a mounting seat 33, and the bottom of the mounting seat 33 is fixedly installed with a grating displacement sensor 34.

[0077] It is used to realize plane detection and can directly transmit the detected data to the terminal for analysis and display, so that the operator can obtain the required plane values ​​and judge whether it is qualified;

[0078] During testing;

[0079] The grating displacement sensor 34 is directly turned on, and the third electric slide 32 can drive the grating displacement sensor 34 to move its position, so as to cooperate with the material moving mechanism 2 below to achieve measurement and detection operations at different positions, so as to improve the detection effect;

[0080] Grating displacement sensor 34, used to measure linear or angular displacement, it measures the moving distance of an object relative to the sensor by reading the light signal of the periodic structure from the grating, it uses the grating principle to detect the displacement of the target, has a very high resolution, can reach micron level or even smaller, the sensor can be directly installed on the required position and component, and does not need to be in direct contact with the measured object, so it has good anti-interference ability and is suitable for high-precision displacement measurement and industrial online control;

[0081] During the measurement and detection process, it is not limited to the detection by the above-mentioned grating displacement sensor 34, but also possible to use a laser flatness measuring instrument for measurement and detection;

[0082] The laser flatness measuring instrument uses the principle of laser interference or projector to obtain the surface flatness information by measuring the changes in the reflected or projected light on the surface of an object.

[0083] like Figure 8 As shown, the fourth electric slide 51 in the flip mechanism 5 is fixedly installed at the bottom of the inner cavity of the box body 1, and a support seat is fixedly installed on the top of the moving end of the fourth electric slide 51, and a second electric push rod 52 is fixedly installed on the top of the support seat;

[0084] A fixing frame 53 is fixedly mounted on the output end of the second electric push rod 52 , a second motor 54 is fixedly mounted on one side of the fixing frame 53 , and a pneumatic clamp 55 is keyed to the output shaft of the second motor 54 .

[0085] The function of flipping the inspected component is realized to facilitate adjustment of the surface to be inspected.

[0086] When turning the material:

[0087] The upper part is directly driven by the fourth electric slide 51 to move until the pneumatic clamp 55 is located outside the inspected part, and then the pneumatic clamp 55 is started to complete the clamping of the material, and then the second electric push rod 52 pushes it to move upward, and stops moving when it reaches a height that can be turned over, and then the second motor 54 is started, and the pneumatic clamp 55 is directly driven by the second motor 54 to rotate, and its maximum rotation range is one circle each in the forward and reverse directions;

[0088] If necessary, after clamping the material, it is necessary to move back to the initial position and then flip it over to avoid obstruction.

[0089] A control method comprises the following steps:

[0090] Step 1: feeding inspection. Place the heat sink to be inspected on the top of the loading plate 26, and then slowly move it horizontally. During the movement, inspect its flatness. The inspection process is divided into moving inspection and stop moving inspection. After moving to the final position, adjust the required height downward and adjust its direction by meshing transmission for secondary inspection.

[0091] Step 2: Fix the material by clamping. During the testing process, the clamping and loosening states need to be repeatedly formed. The movement is completed by the driving force and the meshing transmission force to form the clamping fixation. The clamping limit can be completed by the lateral clamping and elastic setting, and no deviation occurs during the testing process.

[0092] Step three, flipping the material. After the preliminary inspection is completed, the bottom surface of the heat sink needs to be inspected. The pneumatic clamp 55 is started to lightly clamp the heat sink and then lift the height to leave enough space to complete the flipping. The heat sink is flipped to the required inspection state. During the flipping process, the pneumatic clamp 55 is rotated forward and reverse by the second motor 54. After flipping, it is placed in place for another plane inspection.

[0093] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

The device for detecting the plane of a component of a graphics card fan according to claim 1, characterized in that: The bracket (31) in the detection mechanism (3) is fixedly mounted on the top of the outer side of the box body (1); a third electric slide (32) is fixedly mounted on the top of the bracket (31); a mounting seat (33) is fixedly mounted on the bottom of the movable end of the third electric slide (32); and a grating displacement sensor (34) is fixedly mounted on the bottom of the mounting seat (33).

6. A control method, applied to a component plane detection device for a graphics card fan according to any one of claims 1 to 5, characterized in that: The steps include: Step 1: feeding inspection, placing the heat sink to be inspected on the top of the loading plate (26), and then slowly moving it horizontally, while inspecting its flatness during the movement. The inspection process is divided into moving inspection and stopped moving inspection. After moving to the final position, it is moved downward to adjust the required height and its direction is adjusted by meshing transmission to wait for secondary inspection; Step 2: Fix the material by clamping. During the testing process, the clamping and loosening states need to be repeatedly formed. The movement is completed by the driving force and the meshing transmission force to form the clamping fixation. The clamping limit can be completed by the lateral clamping and elastic setting, and no deviation occurs during the testing process. Step 3, turning over the material. After the preliminary inspection is completed, the bottom surface of the heat sink needs to be inspected. The pneumatic clamp (55) is started to lightly clamp the heat sink and then raised to a height, leaving enough space to complete the turning. The heat sink is turned over to the required inspection state. During the turning process, the pneumatic clamp (55) is rotated forward and reversely by the second motor (54). After turning over, it is placed in place for another plane inspection.
