Description

Technical Field

[0001] This utility model relates to the field of heat exchanger manufacturing technology, and in particular to a novel graphite fixture for heat exchangers. Background Technology

[0002] As a highly efficient heat dissipation component, heat exchange plates are widely used in electronic devices. During their manufacturing process, such as sintering, welding, or testing, jigs are required to precisely position and securely clamp the heat exchange plates.

[0003] Most existing graphite jigs have simple structures and usually rely on manual placement of the temperature equalization plate and fixation with bolts or simple manual pressure plates. This method is not only inefficient and labor-intensive, but also the reliability and consistency of clamping depend entirely on the operator's experience. Uneven clamping force or positioning deviation can easily lead to an increased product defect rate. In order to improve efficiency, some automated production lines have begun to use jigs with pneumatic or electric clamping devices. These devices can realize automated clamping action and replace manual operation to a certain extent.

[0004] However, the design of these automated jigs still has limitations. They typically only provide clamping force in one direction, such as clamping from the side or pressing down from the top. For heat spreaders that require high-precision machining, this unidirectional fixing method cannot completely eliminate the slight displacement or vibration that may occur during the machining process, thus affecting the final product quality. In addition, the function of these jigs is relatively simple, limited to "clamping and fixing". The action of "picking up" or "placing" the heat spreader onto the jig still needs to rely on another independent robotic arm or conveying system. This functional separation makes the entire automation process more complicated, increases the difficulty of coordinated control between equipment, and occupies more production space.

[0005] Therefore, this utility model proposes a novel uniform temperature plate graphite fixture to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing heat spreader graphite fixtures, such as simple structure, low positioning accuracy due to only providing unidirectional clamping, and difficulty in achieving stable collaborative operation in automated processes, this utility model aims to provide a novel heat spreader graphite fixture with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a novel graphite fixture for a heat spreader plate, comprising: an upper connecting plate, a main support frame fixedly connected to the upper side of the upper connecting plate, a heat spreader plate placement piece disposed on the main support frame, a clamping mechanism, and an automatic picking mechanism.

[0008] The clamping mechanism and the automatic picking mechanism are independent structures that enable multi-dimensional collaborative operation.

[0009] Furthermore, the clamping mechanism and the automatic picking mechanism are combined in the following manner: the clamping mechanism includes an inner pull plate, which is rotatably connected to a front pull rod. The other end of the front pull rod is linked to a front drive frame disposed on both sides of the inner pull plate. This structure is used to convert the driving force of the main electric push block into a precise opposing clamping action. The automatic picking mechanism includes a front telescopic rod driven by an auxiliary electric push rod. The front end of the front telescopic rod is connected to a pitch-changing component, which drives the picking clamp. This structure is used to realize the gripping and releasing action of the heat exchange plate.

[0010] Preferably, the top of the temperature distribution plate is fixedly connected with a temperature distribution plate limiting groove for initial positioning of the temperature distribution plate.

[0011] Preferably, the clamping mechanism further includes a front connecting rod, a front connecting piece, a front electric push block, and an inner pull rod. The main electric push block drives the front connecting rod, and the front electric push block drives the inner pull rod connected to the inner pull piece via the front connecting piece.

[0012] Preferably, the front end of the front drive frame is connected to an anti-slip component, which includes a front connector and an anti-slip clip made of flexible material.

[0013] Preferably, the automatic picking mechanism further includes a rear connecting frame, a main support plate, and a secondary support frame. The secondary electric push rod is fixed to the main support plate through the rear connecting frame and is supported by the main support plate and the secondary support frame.

[0014] Preferably, the variable pitch assembly includes a rear connecting piece and a pull variable pitch block, and the front end of the front telescopic rod is connected to both the rear connecting piece and the pull variable pitch block. The pull variable pitch block is used to drive the retrieval clamp to open and close.

[0015] Preferably, the front side of the grabber is provided with an anti-slip component, the anti-slip component including a front fixing clip fixedly connected to the front side of the grabber.

[0016] Preferably, as a further limitation of the aforementioned solution, the inner wall of the front fixing clip is provided with a clip anti-slip groove.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of poor positioning accuracy and low automation caused by the single structure of the jig and reliance on manual or unidirectional clamping in the prior art by setting up independent clamping mechanisms and automatic picking mechanisms, which are driven by their respective power sources to achieve collaborative work. It achieves the technical effect of multi-dimensional and automated collaborative clamping and picking of the heat exchange plate, significantly improving operational stability and production efficiency.

[0018] 2. This utility model solves the problem that traditional clamps are difficult to achieve stable and reliable automated action due to their simple structure and imprecise transmission by setting a front drive frame that moves in opposite directions in the clamping mechanism and a gripping clamp driven by a front telescopic rod in the automatic picking mechanism. It achieves the technical effect of ingenious structural design, clear transmission path and precise conversion of linear driving force into efficient clamping and grasping action.

[0019] 3. This utility model solves the problem in the prior art that the workpiece surface is easily damaged or the clamping is unstable due to improper design of the clamping contact surface by setting flexible anti-slip clips and anti-slip grooves on the front end of the clamping mechanism and the automatic picking mechanism, respectively. It achieves the technical effect of providing reliable clamping force while effectively protecting the heat exchange plate and significantly improving the safety of the operation process.

[0020] 4. This utility model solves the problem of the initial position of the heat exchange plate not being fixed before automated operation by setting a heat exchange plate placement piece with a heat exchange plate limiting groove, thus achieving the technical effect of providing accurate initial positioning for subsequent automated clamping and picking, and simplifying the overall process flow.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example: Please refer to Figures 1 to 5 This utility model provides a novel homogenizing plate graphite fixture, which aims to solve the problems of existing homogenizing plate fixtures, such as simple structure, low clamping and positioning accuracy, and difficulty in achieving automated collaborative operation. Figure 1 , Figure 2 and Figure 3 As shown, the overall basic frame of this novel heat spreader graphite fixture includes an upper connecting plate 5. A main support frame 6 is fixedly connected to the upper side of the upper connecting plate 5. The main support frame 6 is rigidly connected to the heat spreader placement piece 7. Multiple heat spreader limiting grooves 8 are fixedly connected to the top of the heat spreader placement piece 7 to provide initial placement limits for the heat spreader. On this basic frame, an independent clamping mechanism 3 and an automatic picking mechanism 4 are also integrated. The clamping mechanism 3 and the automatic picking mechanism 4 are used to clamp and pick up the heat spreader placed in the heat spreader limiting grooves 8 from different dimensions.

[0029] To achieve reliable clamping of the heat spreader, the clamping mechanism 3 in this embodiment converts the linear driving force of the motor into precise clamping action through a linkage assembly. Please refer to the following for details. Figure 3 and Figure 4The structure of the clamping mechanism 3 is described in detail below. The clamping mechanism 3 is powered by a main electric push block 1 and a front electric push block 33. The main electric push block 1 drives the front connecting rod 31. A front connecting piece 32 is fixedly connected to the front side of the front connecting rod 31. The front electric push block 33 is fixedly connected to the front side of the front connecting piece 32. The front electric push block 33 can move back and forth by electrically pulling the inner pulling rod 34. The inner pulling rod 34 drives the inner pulling piece 35 fixedly connected to it to move synchronously. The inner pulling piece 35 is rotatably connected to the front pulling rod 361. The other end of the front pulling rod 361 is linked to the device. The front drive frame 362 is placed on both sides of the inner pull plate 35. When the inner pull plate 35 moves back and forth, it drives the front drive frame 362 through the front pull rod 361, so that the front ends of the upper and lower front drive frames 362 can move closer to each other, thereby achieving a clamping effect. In order to ensure the stability of clamping and the protection of the heat exchange plate, the front end of the front drive frame 362 is fixedly connected to a fixed protection component 37. The fixed protection component 37 includes a front connector 371 fixedly connected to the front side of the front drive frame 362, and a fixed protection clip 372 made of flexible material is fixedly connected to the front side of the front connector 371.

[0030] Based on the above embodiments, the automatic picking mechanism 4 of this utility model can autonomously pick up the temperature distribution plate. Please refer to...

The pitch-changing assembly 45 drives the picking clamp 46 to grasp the heat exchange plate. As a preferred embodiment, the pitch-changing assembly... Component 45 includes a rear connecting piece 451 and a pulling variable pitch block 452.

[0031] Working principle: In this utility model, the main electric push block 1 and the auxiliary electric push rod 2 provide power for the main functional mechanism clamping mechanism 3 and automatic picking mechanism 4. The main electric push block 1 adjusts the distance between the temperature equalization plate and the fixed protection component 37 by pushing the front connecting rod 31 with electricity.
