Description

Technical Field

[0001] This utility model relates to the field of electronic components, and in particular to an assembly and positioning structure. Background Technology

[0002] Electronic components are the basic building blocks of electronic circuits and electronic devices. They possess specific electrical properties and functions, and work together to enable the operation of various electronic systems. To ensure the heat dissipation of the chips used, the industry standard practice is to attach an aluminum heat sink to the chip. However, when the aluminum heat sink and the chip are joined together, misalignment may occur, resulting in reduced heat dissipation efficiency.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: the existing assembly and positioning structure generally includes bolts, chips, aluminum heat sinks and other structures. The existing chips and aluminum heat sinks lack a positioning mechanism when splicing, which may lead to splicing deviation. At the same time, the existing chips also lack a fixing mechanism when splicing, which may cause the chips to slide during splicing.

[0004] Therefore, those skilled in the art have provided an assembly and positioning structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an assembly and positioning structure. The positioning mechanism ensures that the bottom chip will not move, and multiple positioning rods make the splicing of the chip and the heat sink more precise.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembly and positioning structure, including a positioning mechanism and a fixing mechanism. The positioning mechanism includes a screw, multiple positioning rods, a base plate, two sliders, and a second motor. The outer walls of the multiple positioning rods are slidably connected to a moving frame, and the two sliders are slidably connected to two clamping plates inside.

[0007] The fixing mechanism includes two limiting plates, and multiple No. 2 springs are fixedly connected to the ends of the two limiting plates that are furthest from each other.

[0008] Furthermore, the ends of the multiple second springs away from the two limiting plates are fixedly connected to the inner walls of the two movable frames.

[0009] Furthermore, the inner walls of the two movable frames are slidably connected to the outer walls of the two limiting plates, and a heat sink is movably connected to one end of the two limiting plates away from the multiple second springs.

[0010] Furthermore, a locking block is fixedly connected to the outer wall of one end of the movable frame, and a No. 1 motor is fixedly connected to the inner wall of the top of the locking block. The output end of the No. 1 motor is fixedly connected to the top of the screw.

[0011] Furthermore, the bottom of the screw is rotatably mounted on the inner wall of one end of the base plate, and a double-headed screw is rotatably mounted inside the transverse center line of the base plate. The output end of the second motor is fixedly connected to the outer wall of the double-headed screw at the end away from the screw.

[0012] Furthermore, the second motor is fixedly installed on the inner wall of the base plate at the transverse center line away from the screw, and the two clamping plates are each fixedly connected to a first spring at the end near the slider, and the ends of the two first springs away from the two clamping plates are fixedly connected to the inner wall of the slider.

[0013] Furthermore, the outer walls of the two sliders are slidably connected to the outer wall of the base plate, and the bottoms of the plurality of positioning rods are fixedly connected to the top of the base plate.

[0014] Furthermore, the outer wall of the heat sink and the inner wall of the movable frame are slidably connected.

[0015] This utility model has the following beneficial effects:

[0016] 1. The present invention proposes an assembly and positioning structure in which the second motor starts working and drives the double-headed screw to rotate. The double-headed screw causes the two threaded sliders to move inward, pulling the clamping plate and driving the first spring to move along the inner wall of the slider to the front and rear ends. When the two sliders fix the outer walls of both ends of the chip, the two clamping plates are released. The two clamping plates are pulled by the first spring, fixing the front and rear ends of the chip and preventing it from moving during assembly.

[0017] 2. The assembly and positioning structure proposed in this utility model involves first placing the heat sink into the left limiting plate and pressing the second spring to the left to move it to the left. Then, the other end of the heat sink is placed into the right limiting plate. Under the action of the first springs on both sides, the heat sink is fixed. The first motor starts to work and drives the screw to rotate, causing the moving frame to move the heat sink down along the positioning rod. After it is in contact with the top of the chip, the heat sink is fixed together by bolts, adhesives, clamps, etc. The multiple positioning rods ensure that the heat sink will not deviate when it moves up and down.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 The present invention provides an embodiment of an assembly positioning structure, comprising a positioning mechanism 1 and a fixing mechanism 2. The positioning mechanism 1 includes a screw 101, multiple positioning rods 106, a base plate 107, two sliders 110, and a second motor 111. The outer walls of the multiple positioning rods 106 are slidably connected to a movable frame 105. The two sliders 110 are internally slidably connected to two clamping plates 109. The fixing mechanism 2 includes two limiting plates 201. The ends of the two limiting plates 201 furthest from each other are fixedly connected to multiple second springs 202.

[0027] Specifically, the second motor 111 drives the double-headed screw 108 to rotate. The double-headed screw 108 causes the two sliders 110 on the outer wall to move inward, pulling the clamping plate 109 and causing the first spring 104 to move back and forth until the two sliders 110 fix the two ends of the chip. Then, the two clamping plates 109 are released, and the front and rear ends of the chip are fixed under the tension of the first spring 104. By fixing the chip, it is prevented from sliding when splicing with the heat sink 203. First, the heat sink 203 is placed into the limiting plate 201 on one side, and multiple pressure points are pressed to the left. The second spring 202 then places the other end of the heat sink 203 into the right end limit plate 201. The heat sink 203 is fixed by the first springs 104 on both sides. The first motor 103 works, driving the screw 101 to rotate, so that the moving frame 105 moves down along the positioning rod 106 and fits against the top of the chip. Then the heat sink 203 is fixed together by bolts or other means. The moving frame 105 drives the heat sink 203 on the inner wall to move down along multiple positioning rods 106. Because of the multiple positioning rods 106, the heat sink 203 will not shift.

[0028] Reference Figures 1-5 Multiple second-generation springs 202 are fixedly connected to the inner walls of two movable frames 105 at their ends away from the two limiting plates 201. The inner walls of the two movable frames 105 are slidably connected to the outer walls of the two limiting plates 201. Heat sinks 203 are movably connected to the ends of the two limiting plates 201 away from the multiple second-generation springs 202. A locking block 102 is fixedly connected to the outer wall of one end of the movable frame 105. A first-generation motor 103 is fixedly connected to the inner wall of the top of the locking block 102. The output end of the first-generation motor 103 is fixedly connected to the top of the screw 101. The bottom of the screw 101 is rotatably mounted on the inner wall of one end of the base plate 107. A double-headed mechanism is rotatably mounted inside the transverse centerline of the base plate 107. The screw 108 and the output end of the second motor 111 are fixedly connected to the outer wall of the end of the double-headed screw 108 away from the screw 101. The second motor 111 is fixedly installed on the inner wall of the base plate 107 at the transverse center line away from the screw 101. The two clamping plates 109 are fixedly connected to the ends of the sliders 110. The ends of the two first springs 104 away from the two clamping plates 109 are fixedly connected to the inner wall of the sliders 110. The outer walls of the two sliders 110 are slidably connected to the outer wall of the base plate 107. The bottom of the multiple positioning rods 106 is fixedly connected to the top of the base plate 107. The outer wall of the heat sink 203 is slidably connected to the inner wall of the moving frame 105.

[0029] Specifically, the two movable frames 105 provide support for multiple second springs 202 and two limiting plates 201, the locking block 102 provides support for the first motor 103, the bottom of the screw 101 is rotatably set inside the base plate 107, the base plate 107 provides support for the double-headed screw 108 and the second motor 111, and the two clamping plates 109 can fix the front and rear ends of the heat sink 203 through two first springs 104.

[0030] Working principle: When the output end of the second motor 111 is started, it drives the double-headed screw 108 to rotate. The rotation of the double-headed screw 108 causes the two sliders 110 connected by the outer wall threads to move inward. Then, the clamping plate 109 is pulled to drive the first spring 104 to move forward and backward. After the two sliders 110 fix the outer walls of both ends of the chip, the two clamping plates 109 are released. Under the pulling force of the first spring 104, the front and rear ends of the chip are fixed.

[0031] Next, the heat sink 203 is placed inside the limiting plate 201 on one side and pushed to the left to compress multiple second springs 202 to move to the left. Then, the other end of the heat sink 203 is placed inside the limiting plate 201 on the right side and the heat sink 203 is fixed by the first springs 104 on both sides. Then, the first motor 103 is started and the output end rotates to drive the screw 101 to rotate, so that the moving frame 105 moves down along multiple positioning rods 106 to fit against the top of the chip. Then, the heat sink 203 is fixed together by bolts, adhesives, clamps, etc.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
