Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate production technology, and in particular to a liquid cooling plate welding fixture. Background Technology

[0002] Liquid cooling plates are a key component in battery liquid cooling thermal management systems, primarily used for cooling power batteries and energy storage batteries. They cool battery modules and control battery temperature through the flow of liquid. The working principle of a liquid cooling plate involves the circulation of coolant in liquid channels, thereby transferring excess heat and achieving the cooling function. The production process of liquid cooling plates requires welding, which uses flux. Powdered flux is sprayed onto the base plate. Flux helps and promotes the welding process while also providing protection and preventing oxidation. During spraying, flux can be stirred up, or excess flux can accumulate on the surface of the workpiece, affecting the production environment and wasting flux. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a welding fixture for liquid cooling plates.

[0004] The present invention proposes a liquid cooling plate welding fixture, which includes a working chamber and several bearing plates. The working chamber is rectangular, and each bearing plate has a rotating rod fixedly connected to both ends, which is rotatably connected between the two long sides of the working chamber.

[0005] The inner walls of the two short sides of the working chamber are horizontally equipped with trays and telescopic rods. Each of the two trays is slidably connected with a movable plate. Each of the two movable plates is vertically equipped with a positioning plate on its top. The two positioning plates are parallel to each other. The telescopic rods are used to move the movable plates on the trays and change the distance between the two positioning plates.

[0006] The two sets of moving plates and each set of bearing plates are parallel to each other and located on the same horizontal plane. The working chamber is equipped with a drive mechanism to simultaneously control the rotation of each set of bearing plates around the rotating rod.

[0007] Preferably, adjacent support plates are provided with equal gaps.

[0008] Preferably, the drive mechanism includes a motor and a worm gear. The rotating rod on the same side of each set of bearing plates has a portion extending out of the working chamber. Each portion is fixedly equipped with a worm wheel. The motor and the worm gear are installed on the outer wall of the working chamber. Each set of worm wheels meshes with the worm gear. Rotating the worm gear simultaneously drives each set of bearing plates to rotate.

[0009] Preferably, a recovery hopper is installed in the middle of the working chamber, which divides the inner cavity of the working chamber into upper and lower chambers. The upper chamber is the welding chamber, and the lower chamber is the recovery chamber. Each set of the bearing plate, support plate, and moving plate is located in the welding chamber, and the recovery chamber is used to recover flux.

[0010] Preferably, the outer wall of the working chamber is equipped with a fan and a hopper, the inner wall of the welding cavity is equipped with multiple sets of air intakes, the air intakes are located above the support plate, a number of air ducts are connected between the fan and the air intakes, and a return pipe is connected between the hopper and the recovery chamber.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] like Figures 1-3 The liquid cooling plate welding fixture shown includes a working chamber 1 and several bearing plates 2. The working chamber 1 is rectangular. Each set of bearing plates 2 has a rotating rod 201 fixedly connected to both ends, which is rotatably connected between the two long sides of the working chamber 1.

[0021] The inner walls of the two short sides of the working chamber 1 are horizontally equipped with a support plate 4 and a telescopic rod 401. A movable plate 402 is slidably connected to each of the two sets of support plates 4. A positioning plate 403 is vertically installed on the top of each of the two sets of movable plates 402. The two sets of positioning plates 403 are parallel to each other. The telescopic rod 401 is used to drive the movable plate 402 to move on the support plate 4 and change the distance between the two sets of positioning plates 403.

[0022] The two sets of moving plates 402 and each set of bearing plates 2 are parallel to each other and located on the same horizontal plane. The working chamber 1 is equipped with a drive mechanism to simultaneously control each set of bearing plates 2 to rotate about the rotating rod 201 as an axis.

[0023] Preferably, adjacent support plates 2 are provided with equal gaps.

[0024] Preferably, the driving mechanism includes a motor and a worm gear 3. The rotating rod 201 on the same side of each set of bearing plates 2 has a portion extending out of the working chamber 1. Each portion is fixedly equipped with a worm wheel 202. The motor and the worm gear 3 are installed on the outer wall of the working chamber 1. Each set of worm wheels 202 meshes with the worm gear 3. Rotating the worm gear 3 simultaneously drives each set of bearing plates 2 to rotate.

[0025] The motor drives the worm gear 3 to rotate, and the rotating rod 201 drives the bearing plate 2 to rotate through each worm wheel 202, adjusting all the bearing plates 2 to a horizontal state. The liquid cooling plate to be welded is placed on the bearing plate 2. The distance between the two sets of support plates 4 is changed by the two sets of telescopic rods 401. The two sets of positioning plates 403 clamp and position the liquid cooling plate on both sides before welding. When spraying powdered flux, there is a gap between the bearing plates 2 of this application. Using the left and right clamping method on both sides, the excess flux can fall from the gap between the bearing plates 2 to the bottom of the working chamber 1 for recycling. Some flux will be on the bearing plate 2. At this time, the motor drives the worm gear 3 to rotate, flipping the bearing plate 2 and shaking the flux on its upper part to the bottom of the working chamber 1. The other side continues to support the next liquid cooling plate. The moving plates 402 and positioning plates 403 on both sides continue to play the role of clamping and positioning. When not being processed, the motor quickly drives the worm 3 to rotate, which in turn drives each bearing plate 2 to rotate quickly through each worm wheel 202. The centrifugal force drives the bearing plate 2 to rotate, shaking off the flux adhering to the bearing surface.

[0026] Preferably, a recovery hopper 101 is installed in the middle of the working chamber 1. The recovery hopper 101 divides the inner cavity of the working chamber 1 into upper and lower chambers. The upper chamber is the welding chamber and the lower chamber is the recovery chamber. Each set of the bearing plate 2, support plate 4, and moving plate 402 is located in the welding chamber. The recovery chamber is used to recover flux.

[0027] The recovery hopper 101 is configured as a downward sloping ramp, which can separate the welding chamber and the recovery chamber into two independent chambers.

[0028] Preferably, a fan 5 and a hopper 503 are installed on the outer wall of the working chamber 1, and multiple sets of air inlets 501 are installed on the inner wall of the welding cavity. The air inlets 501 are located above the bearing plate 2. Several air ducts 502 are connected between the fan 5 and the air inlets 501, and a return pipe 504 is connected between the hopper 503 and the recovery chamber.

[0029] The flux that is thrown up is drawn into the hopper 503 through the air duct 502 by the air intake 501, and then returned to the recovery chamber through the return pipe 504.

[0030] Preferably, rubber pads are provided on the opposing surfaces of the two sets of positioning plates 403, which can protect the liquid cooling plate during the clamping and positioning process.

[0031] Preferably, the feature is that both sets of the support plates 4 are provided with slide rails, and the bottom of both sets of the movable plates 402 are equipped with pulleys. The pulleys of the movable plates 402 are engaged with the slide rails on the support plates 4 to reduce frictional resistance and facilitate clamping and positioning of the liquid cooling plates.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
