Description

Technical Field

[0001] This invention relates to the field of inverter manufacturing equipment technology, and more specifically to an installation device for inverter heat dissipation modules. Background Technology

[0002] As an important power control device, the frequency converter generates a lot of heat during operation, so it usually needs to be equipped with a heat dissipation module consisting of a metal base and a cooling fan for forced air cooling. The core of assembling this heat dissipation module lies in accurately fixing the cooling fan to the base, which is usually accomplished by screw fastening.

[0003] Currently, the assembly of heat dissipation modules mainly relies on manual labor. In manual assembly, operators need to manually align the fan with the base and tighten multiple screws sequentially, a process that is inefficient. To achieve fully automated assembly, some solutions use high-precision vision recognition systems in conjunction with multi-axis robots for positioning and attachment. While these solutions offer a high degree of automation, they are complex and expensive. Therefore, we propose an installation device for inverter heat dissipation modules. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an installation device for inverter heat dissipation modules. It overcomes the deficiencies of existing technologies, has a reasonable design and compact structure, and solves the problems of low efficiency in manual assembly of existing heat dissipation modules and the complexity and high cost of fully automated assembly systems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for installing a heat dissipation module in a frequency converter, comprising:

[0006] The base has a sliding guide structure extending along its length on its top;

[0007] A conveying mechanism is disposed within the base and arranged along its length;

[0008] A carrier, mounted on the conveying mechanism, is used to carry and transport the heat dissipation module;

[0009] A pair of positioning components are disposed on the base and located on both sides of the conveying mechanism;

[0010] A gantry support is slidably mounted on the sliding guide structure and spans across the top of the conveying mechanism;

[0011] The screw fastening machine is movably mounted on the gantry bracket.

[0012] Preferably, the positioning component includes:

[0013] A fixing seat is installed on the base;

[0014] The guide assembly is mounted on the fixed base;

[0015] The connector is movably mounted on the fixed base;

[0016] A clamping member, located at the end of the connector, is used to clamp the heat dissipation module;

[0017] A driving component, sleeved on the outer wall of the connector, is used to drive its movement;

[0018] The guide component is used to guide the connector to move along a set trajectory.

[0019] Preferably, the guiding assembly includes a pair of inclined guide plates, each guide plate having a guide channel extending along its inclined direction.

[0020] The bottom of the connector is provided with a guide post for inserting a guide channel;

[0021] The clamping member has an L-shaped structure, which allows the fan of the heat dissipation module to be moved and positioned simultaneously when the clamping members on both sides hold the two diagonal sides of the heat dissipation module.

[0022] Preferably, the connector includes a first connecting part and a second connecting part that are relatively adjustable, the driving member is sleeved on the outer wall of the first connecting part, and the second connecting part is connected to the clamping member.

[0023] Preferably, an adjustable connection structure is provided between the first connecting part and the second connecting part, which allows the relative positions of the two parts to be adjusted and fixed by fasteners.

[0024] Preferably, the connection structure includes:

[0025] A slot is provided at the end of the first connecting part for the second connecting part to be inserted;

[0026] A long groove is formed at the top of the first connecting part and communicates with the slot;

[0027] At least one fastener is provided on the second connecting portion and is able to pass through the elongated groove;

[0028] The fastener can be locked at different positions within the elongated groove to fix the relative positions of the first connecting part and the second connecting part.

[0029] Preferably, the fastener includes multiple screws fixed to the second connecting portion and a nut that cooperates with the screws;

[0030] The screw can be placed in the elongated groove, and the relative locking between the first connecting part and the second connecting part is achieved by tightening the nut.

[0031] Preferably, the top of the carrier is provided with a fence frame for circumferentially limiting and supporting the heat dissipation mold base.

[0032] This invention provides an installation device for a heat dissipation module in a frequency converter. It has the following advantages:

[0033] 1. The equipment integrates automatic conveying, precise positioning, and multi-axis screw fastening into a continuous operation cycle. Operators only need to perform initial material loading; all subsequent precise positioning and fastening work is completed automatically by the equipment, significantly reducing the assembly time of a single product, making it especially suitable for mass production.

[0034] 2. The positioning components, with inclined guide channels on both sides, drive the clamping parts to move, enabling simultaneous clamping of the cooling fan at two opposite corners. This positioning method automatically corrects the initial placement deviation of the fan. Operators or robotic arms only need to roughly place the cooling fan in the corresponding area of ​​the base, eliminating the need for time-consuming and laborious precise positioning, thus fundamentally ensuring the accuracy of locking and the efficiency of product assembly.

[0035] 3. The connectors of the positioning components feature an adjustable design, allowing the clamping point position to be adjusted according to the actual size of the cooling fan. This enables the same equipment to adapt to the assembly of cooling modules of various sizes, improving equipment utilization and return on investment. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] See attached document Figure 1-7 An installation device for a frequency converter heat dissipation module includes a base 1, a conveying mechanism 2, a carrier 3, a pair of positioning components, a gantry bracket 5, and a screw fastening machine 6.

[0046] The base 1 has a sliding guide structure extending along its length at its top, such as a pair of parallel linear slide rails or guide rails. The conveying mechanism 2, using a belt conveyor or chain conveyor, is installed inside the base 1 and arranged along its length. The carrier 3 is placed on the conveying surface of the conveying mechanism 2 and moves synchronously with it, used to carry and convey the heat dissipation module. The top of the carrier 3 has a guardrail frame 31, the shape of which is adapted to the contour of the heat dissipation module's base, used to provide circumferential restraint and support when carrying the heat dissipation module base, preventing it from shifting or tipping over during transport.

[0047] A pair of positioning components are mounted on the base 1, located on either side of the conveying mechanism 2. The gantry bracket 5 is slidably mounted on the sliding guide structure at the top of the base 1 via a slider, allowing it to move along a first direction. The gantry bracket 5 spans above the conveying mechanism 2 and the carrier 3. The screw fastening machine 6 is a conventional automatic feeding screw fastening device. It is movably mounted on the crossbeam of the gantry bracket 5 via another drive module, such as a Y-axis slide, allowing it to move along a second direction perpendicular to the first direction. Through the movement of the gantry bracket 5 in the first direction and the movement of the screw fastening machine 6 in the second direction, the screw fastening machine 6 can be positioned at any position in the horizontal plane, facilitating the subsequent fixing of the cooling fan to the base of the cooling module.

[0048] The conveyor mechanism 2 drives the carrier 3 carrying the heat dissipation module to the preset installation position. Then, a pair of positioning components move synchronously from both sides to clamp and precisely position the heat dissipation module, aligning the mounting holes of the screws to be tightened with the downward path of the screw fastening machine 6's bit. After positioning, the gantry bracket 5 and the screw fastening machine 6 move according to the preset program to above the first screw hole. The screw fastening machine 6 then lowers to tighten the first screw, and then moves to the next hole until all screws on the cooling fan are installed. After completion, the positioning components release, the conveyor mechanism 2 delivers the finished product, and loads the next heat dissipation module to be installed, repeating the cycle.

[0049] Each positioning component includes a mounting base 41, a guide assembly, a connector 44, a clamping member 46, and a drive member 47.

[0050] A fixed base 41 is mounted on a base 1. A guide assembly is mounted on the fixed base 41 to guide the connector 44 to move along a preset trajectory. In a preferred embodiment, the guide assembly includes a pair of inclined guide plates 42, which are arranged in parallel. Each guide plate 42 has a guide channel 43 extending along its inclined direction. The guide channel 43 is a guide groove structure, and the guide groove forms a 45° angle with the horizontal plane.

[0051] The connector 44 is movably mounted on the fixed base 41. The bottom of the connector 44 has a pair of guide posts 45 that insert into guide channels 43; each guide post 45 is inserted into a different guide channel 43. The drive member 47 is preferably a linear drive device, such as a cylinder or electric actuator, with a fixed cylinder body or main body, and its piston rod or push rod end connected to the connector 44. More specifically, the piston rod end of the drive member 47 typically has a sleeve that fits onto and is fixedly connected to the outer wall of the connector 44, thereby driving the connector 44 to move as a whole. When the drive member 47 operates, it pushes the connector 44 to move, forcing the guide posts 45 at its bottom to slide along the inclined guide channels 43. Because the guide channels 43 are inclined, the connector 44 tilts under the drive of the drive member 47.

[0052] The clamping member 46 is connected to the end of the connector 44. The clamping member 46 has an L-shaped structure. When the clamping members 46 on both sides clamp the two opposite sides of the heat dissipation module at the same time, they can simultaneously push the fan of the heat dissipation module to move and position. When placing the fan on the base of the heat dissipation module, there is no need for precise positioning, which greatly improves the placement efficiency.

[0053] To accommodate the mounting of fans in cooling modules of different sizes and specifications, the connector 44 is designed as an adjustable mechanism. Specifically, the connector 44 includes a first connecting part 441 and a second connecting part 442 that are relatively adjustable. The sleeve of the drive member 47 is fitted onto the outer wall of the first connecting part 441, and the two are slidably connected. The second connecting part 442 is connected to the clamping member 46. An adjustable connection structure is provided between the first connecting part 441 and the second connecting part 442, which allows the relative positions of the two to be adjusted and fixed by fasteners.

[0054] In one specific embodiment, the connecting structure includes a slot 443 formed at the end of the first connecting portion 441 for insertion of the end of the second connecting portion 442; and an elongated groove 445 formed at the top of the first connecting portion 441 and communicating with the slot 443. At least one screw 444 is fixedly disposed on the second connecting portion 442. During adjustment, the position of the screw 444 inserted into the elongated groove 445 can be adjusted by loosening the nut on the screw 444. After adjustment, the nut on the screw 444 is tightened, and the relative position of the first connecting portion 441 and the second connecting portion 442 is locked by the clamping force between the nut and the top of the first connecting portion 441.

[0055] Working principle: The operator or the loading robot places the heat dissipation module base into the enclosure frame 31 of the carrier 3, and initially places the heat dissipation fan in the approximate corresponding position of the base.

[0056] When the conveyor mechanism 2 is started, the drive carrier 3 and the heat dissipation module (base + pre-installed fan) it carries move smoothly along the length of the equipment to the preset screw installation position, and then the conveyor mechanism 2 stops.

[0057] At this time, the drive components 47 on both sides of the conveyor line move synchronously, driving the connecting component 44 to move. The guide post 45 at the bottom of the connecting component 44 is forced to slide along the inclined guide channel 43. At this time, the clamping components 46 on both sides will move towards the two opposite corners of the cooling fan. The cooling fan is preferably a fan with a rectangular outer wall structure. When the clamping components 46 on both sides contact the opposite corners of the cooling fan, they will push the inclined cooling fan to move. Under the continuous pushing of the clamping components 46, the position of the cooling fan is gradually and automatically corrected to the appropriate position. At this time, all the screw mounting holes on the cooling fan and the cooling module base are precisely aligned.

[0058] After positioning, the gantry bracket 5 is moved along the first direction (e.g., the X-axis), while the screw fastening machine 6 moves along the second direction (e.g., the Y-axis) on the gantry beam. The screw fastening machine 6 moves to directly above the first screw hole. The screwdriver bit automatically lowers, picks up, and screws in the first screw. After completion, the bit is lifted. The screw fastening machine 6 automatically moves to the next screw hole in sequence, repeating the fastening action until all screws on the cooling fan are installed. After all screws are fastened, the drive components 47 on both sides move synchronously in opposite directions, driving the connecting component 44 and the clamping component 46 to retreat and reset along the inclined trajectory, completely releasing the installed cooling module.

[0059] Conveying mechanism 2 restarts, sending carrier 3, which carries the secured heat dissipation module, out of the installation station. The equipment returns to the initial state of the first stage, ready to receive and process the next workpiece, and begins a new work cycle.
