Description

A lifting tooling fixture Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a liftable tooling fixture. Background Technology

[0002] The soldering and assembly process of heat dissipation modules is a crucial step in the manufacturing of electronic device heat dissipation systems, involving multiple aspects such as material selection, process control, and quality inspection. The components of a heat dissipation module include: a heat sink substrate (usually made of aluminum or copper) responsible for contact with the heat source; heat pipes / vapor chambers that transfer heat through internal working fluid phase changes; and heat dissipation fins that increase the heat dissipation area, primarily made of aluminum or copper. Soldering materials include solder paste, silver paste, and indium alloys.

[0003] In the welding process, when the copper sheet thickness is less than 0.5mm, the copper block is difficult to position. Displacement is prone to occur, and the tooling fixture cannot be effectively positioned, resulting in failure to meet production requirements. To effectively limit the position of thinner copper sheets, this application proposes a liftable tooling fixture to solve the aforementioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a liftable tooling fixture with advantages such as flexible adjustment and strong adaptability. It solves the problem that copper sheets are prone to misalignment due to thickness during the welding process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liftable tooling fixture, including a welding fixture base, a threaded C-type fixing clamp, a welding fixture cover disposed on the threaded C-type fixing clamp, and a heat dissipation module, wherein the number of the threaded C-type fixing clamps is two;

[0006] The welding fixture base includes a welding base, and a lifting sliding block is embedded on the bottom side of the welding base. A lifting positioning pin for fixing the lifting sliding block is detachably installed on the bottom side of the welding fixture base. The lifting positioning pin is provided with a fixing screw for fixing to the welding fixture base.

[0007] Furthermore, the welding base has an internal mounting groove for the heat dissipation module and the welding fixture cover, and four positioning shafts in a rectangular arrangement are fixed on the outer surface of one end of the welding base.

[0008] Furthermore, the heat dissipation module includes heat dissipation fins and heat sinks, with a heat pipe fixedly connected between the heat dissipation fins and heat sinks. A copper sheet is provided on the lower surface of the heat sinks. The heat pipes are arc-shaped, and both the heat pipes and heat dissipation fins are embedded inside the mounting groove.

[0009] Furthermore, the outer surface of the heat sink is fixed with two symmetrically distributed connecting pieces, and the two ends of the two connecting pieces are respectively inserted into four positioning shafts.

[0010] Furthermore, the welding fixture cover is L-shaped, the welding fixture cover is adapted to the mounting groove, and reinforcing ribs are fixed between the outer surfaces of opposite sides of the welding fixture cover.

[0011] Furthermore, the threaded C-type fixing clamp includes a C-type frame, on which a lifting screw is installed by an internal thread, and a clamping block is fixed at the bottom end of the lifting screw.

[0012] Furthermore, a nut is welded to the top of the lifting screw, and the two threaded C-shaped fixing clamps are arranged in the X and Y axis directions, with the welding base fitting against the inner bottom wall of the two C-shaped frames.

[0013] Compared with the prior art, this utility model provides a liftable tooling fixture, which has the following beneficial effects:

[0014] 1. This liftable tooling fixture, by adding a lifting device inside the base of the tooling fixture, lowers the positioning base when placing copper sheets, making the surrounding positioning retaining wall higher, effectively restricting the position of thinner copper sheets.

[0015] 2. This liftable tooling fixture increases the contact area with air through the arc-shaped design of the heat pipe, thereby improving heat dissipation efficiency. Utilizing the excellent thermal conductivity of copper sheets, it can quickly conduct the heat generated by the workpiece to the heat sink, and then dissipate it through the heat sink fins, ensuring the stability of the workpiece temperature during the welding process and improving the welding quality.

Detailed Implementation

[0020] 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.

[0021] Please refer to Figures 1 to 3. In this embodiment, a liftable tooling fixture includes a welding fixture base 1, a threaded C-type clamp 2, a welding fixture cover 3 mounted on the threaded C-type clamp 2, and a heat dissipation module 4. There are two threaded C-type clamps 2. Specifically, each threaded C-type clamp 2 includes a C-shaped frame 201, with a lifting screw 202 threaded inside the C-shaped frame 201. A clamping block 203 is fixed to the bottom end of the lifting screw 202. It should be noted that a nut is welded to the top of the lifting screw 202, and the two threaded C-type clamps 2 are arranged in the X and Y axis directions.

[0022] In this embodiment, the welding fixture base 1 includes a welding base 101. A lifting sliding block 104 is embedded in the bottom side of the welding base 101. A lifting positioning pin 103 for fixing the lifting sliding block 104 is detachably installed on the bottom side of the welding fixture base 1. A fixing screw 102 for fixing the lifting sliding block 104 is provided inside the lifting positioning pin 103. The welding base 101 has an internal mounting groove for the heat dissipation module 4 and the welding fixture cover 3. Four positioning shafts arranged in a rectangular shape are fixed to the outer surface of one end of the welding base 101. The welding base 101 is in contact with the inner bottom wall of the two C-shaped frames 201. It should be noted that the bottom side of the welding base 101 has a groove and a positioning groove, and the lifting sliding block 104 is installed in the positioning groove. The groove is adapted to the cross-section of the C-shaped frame 201. The lifting sliding block 104 moves upward by the abutting engagement between the C-shaped frame 201 and the groove. The lifting sliding block 104 has a through hole inside that works in conjunction with the lifting positioning pin 103.

[0023] The lifting sliding block 104 embedded on the bottom side of the welding base 101 in this application, together with the detachable lifting positioning pin 103, allows for flexible adjustment of the height of the lifting sliding block 104. This enables the fixture to adapt to the welding needs of workpieces of different sizes and shapes, effectively expanding the applicability of the fixture and reducing the cost and time of frequently changing fixtures due to differences in workpieces.

[0024] In this embodiment, the heat dissipation module 4 includes heat dissipation fins 401 and heat sinks 403. A heat pipe 402 is fixedly connected between the heat dissipation fins 401 and the heat sinks 403. A copper sheet 404 is disposed on the lower surface of the heat sinks 403. The heat pipe 402 has an arc shape, and both the heat pipe 402 and the heat dissipation fins 401 are embedded in the mounting groove. The heat pipe 402 fixedly connected between the heat dissipation fins 401 and the heat sinks 403, and the copper sheet 404 disposed on the lower surface of the heat sinks 403, form a highly efficient heat dissipation system in the heat dissipation module 4. The arc shape design of the heat pipe 402 increases the contact area with air, improving heat dissipation efficiency; the copper sheet 404 has good thermal conductivity, which can quickly conduct the heat generated by the workpiece to the heat sinks 403, and then dissipate it through the heat dissipation fins 401, ensuring the stability of the workpiece temperature during the welding process and improving the welding quality.

[0025] It should be noted that two symmetrically distributed connecting pieces are fixed to the outer surface of the heat sink 403, and the two ends of the two connecting pieces are respectively inserted into four positioning shafts. The four rectangularly distributed positioning shafts fixed to one end of the outer surface of the welding base 101 are inserted into the two symmetrically distributed connecting pieces on the outer surface of the heat sink 403, providing precise positioning for the heat dissipation module 4, ensuring the accurate position of the heat dissipation module 4 during installation, and avoiding uneven heat dissipation or other problems caused by positioning deviations. The copper sheet 404 is placed above the lifting sliding block 104. When the lifting sliding block 104 is not in the threaded C-type fixing clamp, it is in a sunken state. Due to the deep positioning groove inside the welding base 101, the copper sheet 404 can be effectively positioned. After all the parts of the heat dissipation module 4 are placed, the welding fixture cover 3 is put on, and two sets of threaded C-type fixing clamps 2 are installed in sequence. When the threaded C-type fixing clamps 2 are locked, the inner bottom wall of the C-shaped frame 201 supports the lifting sliding block 104, making it rise. At this time, the lifting sliding block 104 drags the copper sheet 404 upward to contact the heat sink 403. Then, the lifting screw 202 is rotated to drive the clamp 203 to move downward, thereby fixing the threaded C-type fixing clamp 2. After the threaded C-type fixing clamp 2 is fixed, the copper sheet 404 is in close contact with the heat sink 403. The various parts of the heat dissipation module 4 are pressed together with the welding base 101 and the lifting sliding block 104 on the welding fixture cover 3, respectively. The welding fixture cover 3 is L-shaped and fits the mounting groove. Reinforcing ribs are fixed between the outer surfaces of opposite sides of the welding fixture cover 3.

[0026] The working principle of the above embodiments is as follows:

[0027] First, place each part of the heat dissipation module 4 in sequence. During installation, place the copper sheet 404 that needs to be positioned above the lifting sliding block 104. When the lifting sliding block 104 is not in the threaded C-type fixing clip 2, it is in the sunken state. Since the positioning groove inside the welding base 101 is deep, the copper sheet 404 can be effectively positioned.

[0028] After all the parts of the heat dissipation module 4 are placed in, the welding fixture cover 3 is then placed on top. Two sets of threaded C-type fixing clips 2 are then installed in sequence. When the threaded C-type fixing clips 2 are locked, the inner bottom wall of the C-shaped frame 201 supports the lifting sliding block 104, which raises the C-shaped frame 201. At this time, the lifting sliding block 104 drags the copper sheet 404 upward and into contact with the heat sink 403. Then, the lifting screw 202 is rotated to move the clamp block 203 downward, thereby fixing the threaded C-type fixing clips 2. After the threaded C-type fixing clips 2 are fixed, the copper sheet 404 is in close contact with the heat sink 403. All the parts of the heat dissipation module 4 are pressed together with the welding base 101 and the lifting sliding block 104 on the welding fixture cover 3.

[0029] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
