Description

Technical Field

[0001] This utility model relates to the field of tinning technology for electronic wire harnesses, and in particular to a tinning equipment for preparing electronic wire harnesses. Background Technology

[0002] Wire harnesses are the wiring components that connect various parts in a laptop computer. They consist of core wires, insulation, braiding, and an outer sheath. The quality of the wire harness directly affects whether the entire laptop computer can work normally and safely. During the wire harness manufacturing process, the outer sheath needs to be stripped and the core wires need to be tinned to facilitate subsequent processing. Tinning is an important step in the electronic wire harness manufacturing process, which directly affects the conductivity, connection reliability, and service life of the electronic wire harness.

[0003] Currently, in terms of production efficiency, traditional electronic wire harness tinning equipment on the market mostly relies on manual or semi-automatic operation. The processes of wire harness gripping, tinning, and transfer depend on manual intervention, making the operation process cumbersome. This not only consumes a lot of manpower but also results in slow production speed, making it difficult to meet the growing demand for large-scale production. Consequently, production costs remain high, and economic benefits are difficult to improve. Furthermore, the cooling systems of some equipment cannot achieve uniform and rapid cooling of the tinned wire harness. For example, natural cooling takes a long time and is easily affected by environmental factors, resulting in uneven stress distribution within the tin layer, which can easily lead to quality problems such as tin peeling and poor soldering. On the other hand, simple air cooling or water cooling methods may cause localized thermal stress concentration in the wire harness due to excessively fast or uneven cooling rates, which also reduces the product qualification rate and affects the overall performance and reliability of the electronic wire harness. Utility Model Content

[0004] The purpose of this invention is to provide a tinning process for electronic wire harness preparation, which solves the problems of cumbersome traditional operation procedures, which not only consume a lot of manpower, but also have slow production speed and uneven cooling.

[0005] To achieve the above objectives, this utility model provides a soldering equipment for preparing electronic wire harnesses, including a soldering box and an auxiliary mechanism. The auxiliary mechanism is installed in the center of the inside of the soldering box. The auxiliary mechanism includes a rotary motor, a rotating rod, and a limiting groove. The rotary motor is fixedly installed in the center of the inside of the soldering box. The output end of the rotary motor is connected to the rotating rod. A fixing block is fixedly installed above the rotating rod. The fixing block is fixed to the rotating rod by welding. A limiting groove is opened at the end of the rotating rod away from the drive motor. The rotating rod is movably arranged inside the limiting groove. Several auxiliary mechanisms are provided and connected horizontally in sequence. The limiting groove is located on one side of the drive motor.

[0006] The tin-storing box has a support column fixedly connected to its bottom end, and a base fixedly connected to the bottom end of the support column. An observation window is provided on one side of the tin-storing box.

[0007] The fixing block is fixedly connected to a connecting plate on one side, and an electric gripper is installed on the end of the connecting plate away from the fixing block. A sponge pad is fixedly attached to the inner side of the electric gripper.

[0008] The tin-stripping box has a feed inlet on one side of its top, and the feed inlet and the electric gripper are located on the same vertical plane. A tin-stripping pool is fixedly installed at the bottom of the electric gripper, and the tin-stripping pool is located inside one end of the tin-stripping box.

[0009] The tin box has a cooling chamber on one side of its top, an air inlet pipe on the top of the cooling chamber, an air outlet pipe at the bottom of the cooling chamber, and a refrigeration module installed inside the cooling chamber.

[0010] The tin-stripping box has a discharge port at the bottom of the side away from the tin-stripping pool. An inclined plate is provided on one side of the discharge port, and a rubber pad is attached to the top of the inclined plate.

[0011] This utility model discloses an electronic wire harness preparation and tinning processing equipment. An electric gripper automatically picks up and fixes the electronic wire harness, placing it into the tinning bath through the feed inlet. A rotary motor drives a rotating rod, causing the fixed block and electric gripper to mechanically rotate and rotate, feeding the electronic wire harness onto an inclined plate and out through the discharge port. Multiple auxiliary mechanisms, horizontally connected in sequence, can meet the needs of large-scale production, effectively improving production efficiency and economic benefits. Through the coordinated operation of the cooling chamber, air inlet pipe, air outlet pipe, and refrigeration module, after the electronic wire harness is tinned, the refrigeration module cools the air to a suitable temperature, which is then discharged through the air outlet into the tinning bath to remove heat from the tin layer surface, achieving rapid and uniform cooling and improving product quality.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-4 A tinning processing device for electronic wire harness preparation includes a tinning box 1 and an auxiliary mechanism 2. The auxiliary mechanism 2 is installed in the center of the tinning box 1. The auxiliary mechanism 2 includes a rotary motor 201, a rotating rod 202, and a limiting groove 203. The rotary motor 201 is fixedly installed in the center of the tinning box 1. The output end of the rotary motor 201 is connected to the rotating rod 202. A fixing block 204 is fixedly installed above the rotating rod 202. The fixing block 204 is fixed to the rotating rod 202 by welding. A limiting groove 203 is opened at the end of the rotating rod 202 away from the drive motor. The rotating rod 202 is movably arranged inside the limiting groove 203. Several auxiliary mechanisms 2 are provided and connected horizontally in sequence. The limiting groove 203 is located on one side of the drive motor. The electronic wire harness can be automatically gripped and fixed by an electric gripper 7. The wire harness is put into the bottom end of the tinning bath 10 through the feed port 9 for tinning operation. The rotary motor 201 drives the rotating rod 202 to rotate, which drives the fixing block 204 and the electric gripper 7 to rotate mechanically.

[0020] The bottom of the tin-storing box 1 is fixedly connected to a support column 3, and the bottom of the support column 3 is fixedly connected to a base 4. An observation window 5 is provided on one side of the tin-storing box 1. The base 4 provides stable support, and the observation window 5 on one side facilitates viewing of its interior.

[0021] One side of the fixing block 204 is fixedly connected to a connecting plate 6. An electric gripper 7 is installed at the end of the connecting plate 6 away from the fixing block 204. A sponge pad 8 is fixedly attached to the inner side of the electric gripper 7. The sponge pad 8 on the inner side of the electric gripper 7 can play a buffering and protective role when gripping the wire harness, preventing damage to the surface of the wire harness.

[0022] The top side of the solder feeding box 1 has a feeding port 9, which is located on the same vertical plane as the electric gripper 7. The bottom of the electric gripper 7 is fixedly provided with a solder pool 10, which is located inside the solder feeding box 1. By positioning the solder pool 10 vertically to the feeding port 9, when an electronic wire harness is fed in, it can be accurately clamped onto the electric gripper 7, facilitating the next step and thus improving production efficiency.

[0023] The top side of the tin box 1 is provided with a cooling chamber 11, an air inlet pipe 12 is opened above the cooling chamber 11, an air outlet pipe 13 is connected to the bottom of the cooling chamber 11, a refrigeration module 14 is installed inside the cooling chamber 11, and the sponge pad 8 inside the electric gripper 7 can play a buffering and protective role when gripping the wire harness to prevent damage to the surface of the wire harness.

[0024] The solder box 1 has a discharge port 15 at the bottom of the side away from the solder bath 10. A ramp 16 is provided on one side of the discharge port 15. A rubber pad 17 is attached to the top of the ramp 16. The tinned electronic wire harness is flipped and moved to the discharge port 15 at the bottom of the side of the solder box 1 away from the solder bath 10, and falls onto the ramp 16 on the side of the discharge port 15. The rubber pad 17 above the ramp 16 can prevent the wire harness from being impacted when it slips down.

[0025] In use, the electronic wire harness is inserted through the feed port 9 on one side of the top of the soldering box 1. The sponge pad 8 inside the electric gripper 7 provides cushioning and protection when gripping the wire harness, preventing damage to the surface of the wire harness. After the electric gripper 7 automatically grips and fixes the electronic wire harness, it is fed vertically downward from the feed port 9 into the soldering pool 10 located at the bottom for soldering. After soldering is completed, the rotary motor 201 fixed in the center of the soldering box 1 starts, and the rotary rod 202 connected to its output end begins to rotate. This drives the fixing block 204 welded to the rotary rod 202, the connecting plate 6 connected to one side of the fixing block 204, and the electric gripper 7 to perform a flipping motion. The soldered electronic wire harness is flipped and moved to the far side of the soldering box 1. At the bottom of the solder bath 10, the wire harness falls onto the inclined plate 16 on one side of the solder bath 16. The rubber pad 17 above the inclined plate 16 can prevent the wire harness from being impacted when it slips down. Then the wire harness slides out of the equipment through the solder bath 15. At the same time, during the flipping and moving process, the soldered electronic wire harness will pass under the cooling chamber 11 set on the top side of the solder bath 1. The cooling module 14 in the cooling chamber 11 cools the air to a suitable temperature. The cooled air enters the cooling chamber 11 from the air inlet pipe 12 and is discharged into the solder bath 1 through the air outlet pipe 13, evenly surrounding the electronic wire harness, carrying away the heat on the surface of the solder layer, achieving rapid and uniform cooling, effectively preventing the solder surface from falling off, and ensuring product quality.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
