Description

Technical Field

[0001] This application relates to an automatic welding device and a welding method. Background Technology

[0002] For relevant prior art, please refer to Chinese Utility Model Patent CN217217244U, which discloses a heat dissipation device, mainly including a heat pipe, a heat dissipation fin fixed to one end of the heat pipe, a CPU heatsink fixed to the other end of the heat pipe, and a cooling fan used in conjunction with it. This type of heat dissipation device is mainly used to be installed inside electronic devices (such as laptops) to dissipate heat from heat-generating components (such as CPUs) inside the electronic devices.

[0003] In the manufacturing process of this type of heat dissipation device, the fixing of the heat dissipation fins and CPU heat sink to the two ends of the heat pipe is generally achieved by soldering, mainly tin soldering. The conventional method is to place the heat pipe, heat dissipation fins and CPU heat sink in a carrier, pre-apply solder paste to the contact positions between the heat pipe and the heat dissipation fins and CPU heat sink, and constrain them with bolts to ensure effective contact between the heat pipe and the heat dissipation fins and CPU heat sink at the required soldering positions. Then, the entire carrier is placed in a reflow oven for soldering. After the soldering is completed, it is taken out of the reflow oven and cooled before the product is disassembled from the carrier.

[0004] This manufacturing method has at least the following problems: First, after placing the product to be welded into the carrier, bolts need to be tightened, which is usually done manually, making it time-consuming and labor-intensive. Second, during reflow soldering, the entire product (including heat pipes, heat sink fins, and CPU heatsink) and the carrier are indiscriminately added for welding, which is energy-intensive and inefficient. Third, after welding, natural cooling is required, and the product needs to be removed by manually unscrewing the carrier bolts, which is time-consuming, inefficient, and labor-intensive. Ultimately, this leads to increased manufacturing costs.

[0005] Therefore, it is necessary to design a new automatic welding equipment and welding method to solve the above problems. Summary of the Invention

Liquid cooling channels are formed directly or indirectly on the welded body and have inlet and outlet ports; The liquid cooling assembly is equipped with an inlet pipe joint connected to the inlet and an outlet pipe joint connected to the outlet. The liquid cooling assembly cools the welding functional surface of the welding body by delivering coolant and allowing it to flow through the liquid cooling channel.

[0008] Furthermore, limiting members are provided on both sides of the corresponding welding position of the bearing surface along the first direction, and an elastic push rod assembly is formed on at least one of the limiting members. The elastic push rod assembly includes a push rod body and an elastic body.

[0009] Furthermore, a limiting protrusion is formed on the main body of the push rod along the first direction, and a corresponding groove is formed on the side of the carrier; When the carrier moves from the waiting position to the welding position along the second direction, the protrusion scrapes and slides on the side of the carrier and finally engages with the groove to limit its position. The push rod body is restricted at the welding position by two limiting members located on both sides along the second direction.

[0010] Furthermore, a heating element is installed inside the welding body, and along a third direction, the heating element is located at the midpoint between the liquid cooling channel and the welding functional surface.

[0011] Furthermore, the welding body has a mounting hole extending in a transverse direction perpendicular to the third direction, and a heating rod as a heating element is inserted into the mounting hole. The axial direction of the heating rod is parallel to the plane where the welding functional surface is located.

[0012] Furthermore, the welding body includes a mounting block and a functional block assembled onto the mounting block, wherein the welding functional surface, liquid cooling channel, inlet and outlet are all formed in the functional block; The welding functional surface protrudes downward along a third direction from the lower surface of the mounting block; The functional block is detachable from the mounting block.

[0013] Furthermore, the welding body also includes a support block, which is stacked with the mounting block along a third direction, and the functional block is located between the mounting block and the support block along a third direction; The welding functional surface passes through the support block along a third direction and exposes the support block.

[0014] Furthermore, at least two functional blocks are provided on the same support block, and the two functional blocks are spaced apart along a lateral direction perpendicular to the third direction; The welding functional surface of each functional block passes through the support block downward along a third direction and protrudes from the lower surface of the support block; An excessively protruding rib is formed on the lower surface of the support block, protruding downward along a third direction. The two ends of the excessively protruding rib are adjacent to the welding functional surfaces of at least two functional blocks located on the same support block, such that the two welding functional surfaces are flush with the lower surface of the excessively protruding rib.

[0015] Furthermore, the stop pawl does not contact the conveying surface during its entire stroke along the third direction, and / or the pusher pawl does not contact the conveying surface during its entire stroke along the second direction.

[0016] To achieve the aforementioned objective, this application also provides the following technical solution: A welding method using an automatic welding device, comprising the automatic welding device as described in any one of the above claims, wherein the method comprises at least the following steps: S1. Place the carriers carrying the products to be welded one by one on the conveying surface of the conveying module, and the conveying module will convey the carriers on it along the first direction. S2. The drive stop pawl moves downward along a third direction and stops one of the carriers in the waiting position; S3.

The welding body heats the product to be welded through the welding functional surface to perform contact heating welding. S5. After step S4 is completed, coolant is delivered through the liquid cooling component and flows through the liquid cooling channel to cool the welding body, and is transferred to the product to be welded through the welding functional surface to cool the product to be welded. S6. Drive the welding body to move upwards along the third direction to return to its original position.

[0017] Furthermore, the welding module also includes a sensing component, which is disposed on the side of the conveying module away from the bearing surface along the second direction. The method further includes the following steps: Before executing step S2, step S20 is also included: detecting whether there is a vehicle being transported by the transport surface at the corresponding position of the transport surface through the sensing component; if there is a vehicle, then step S2 is executed.

[0018] Furthermore, multiple welding modules 3 are provided and arranged along the first direction; After step S1, the main control unit of the equipment prioritizes driving the first stop claw located at the end of the conveying surface in the first direction to execute step S2; Then, in the first direction, the second stop pawl adjacent to the first stop pawl performs step S2; This process continues sequentially until, in the first direction, the last stop claw located at the beginning of the conveying process on the conveying surface executes step S2. When multiple stop claws perform step S2, the stop claw that is closer to the end point of the conveying surface along the first direction is always executed first, and the second stop claw is executed only after the first stop claw has completed step S2. In addition, before executing step S2, the main control unit of the equipment must first identify whether the welding component corresponding to the stop claw has completed the welding action. If it has been completed, the corresponding stop claw can execute step S2.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] For all descriptions of directions in this application, please refer to [link / reference]. Figure 1 and Figure 2The X-axis is the first direction (the direction of the conveyor), the Z-axis is the second direction (the direction in which the conveyor and the bearing surface are side by side), and the Y-axis is the third direction (the vertical direction of the actual device).

[0035] Please refer to the reference. Figures 1 to 13 As shown, the automatic welding equipment of this application includes a main body 100 and a conveying module 1, a welding platform 2, and a welding module 3 installed on the main body 100. The conveying module 1 is actually a conveyor belt assembly with a conveying surface 11, which can convey the carrier A carried on it along a first direction. The welding platform 2 can be part of the main body 100 or an independent module installed on the main body 100 and arranged side by side with the conveying module 1. The welding platform 2 has a bearing surface 21 arranged side by side with the conveying surface 11 along a second direction. The welding module 3 includes a stop component 31, a pusher mechanism 32, and a welding component 33 that cooperate with each other.

[0036] The stop assembly 31 can be a two-axis moving platform (Y-axis and Z-axis). The stop assembly 31 has a stop claw 311, which is located directly above the bearing surface 21. In a preferred design, the stop assembly 31 can be driven by a drive element such as a cylinder, hydraulic cylinder, or linear motor. In this embodiment, the stop claw 311 can move along a second direction and a third direction, enabling the carrier A, which is conveyed by the conveying surface 11, to be stopped in a stationary position (not labeled) relative to the stop assembly 31.

[0037] Furthermore, the pushing mechanism 32 can also be a two-axis moving platform (Y-axis and Z-axis). The pushing mechanism 32 has a pushing claw 321. The pushing claw 321 initially rests on the side of the conveying surface 11 away from the bearing surface 21 along the second direction. The pushing claw 321 can be driven by a driving element such as a cylinder, hydraulic cylinder, or linear motor. In this embodiment, the pushing claw 321 can move at least along the second direction, enabling it to push the carrier A located at the position to be rotated to the welding position (not labeled) on the bearing surface 21.

[0038] In one embodiment, the welding assembly 33 can also be a two-axis moving platform (X-axis and Y-axis). The welding assembly 33 has a welding body 331, which is movable in a third direction (also driven by a drive element such as a cylinder, hydraulic cylinder, or linear motor). A welding functional surface 332 is formed on the welding body 331, facing downward in the third direction toward the bearing surface 21. The welding body 331 can generate heat itself or be passively heated by other elements integrated on the welding body 331 or the welding assembly 33. The welding body 331 can move in the third direction such that the welding functional surface 332 is pressed against the product B to be welded, which is located at the welding position and supported on the carrier A, for contact heating welding.

[0039] Furthermore, the welding body 331 also includes a liquid cooling module (not labeled), which forms a flow channel and has an inlet 41 and an outlet 42. The automatic welding equipment also includes a liquid cooling assembly (not shown), which has an inlet pipe connector 51 connected to the inlet 41 and an outlet pipe connector 52 connected to the outlet 42. The liquid cooling assembly cools the welding functional surface 332 of the welding body 331 by supplying coolant that flows through the liquid cooling channel. Rapid cooling of the welding position of the product B to be welded is achieved through the welding functional surface 332.

[0040] In one embodiment (illustrative embodiment of this application), the liquid cooling module can be an independent, detachable component assembled onto the welding body 331. Please refer to the reference for details. Figures 2 to 13As shown, the welding body 331 includes a mounting block 3311 and a functional block 3312 assembled onto the mounting block 3311. The welding functional surface 332 is formed on the functional block 3312. The liquid cooling module is a meandering liquid flow channel formed within the functional block 3312, and the inlet 41 and outlet 42 are the inlet and outlet of the liquid flow channel within the functional block 3312. The welding functional surface 332 protrudes downward along a third direction from the lower surface 33110 of the mounting block 3311. The functional block 3312 is detachable from the mounting block 3311. In a more preferred embodiment, by providing a separate functional block 3312 and mounting block 3311, the functional block 3312 and mounting block 3311 can be made of different materials, preferably with the thermal conductivity of the functional block 3312 being superior to that of the mounting block 3311. This allows the welding body 331 to rapidly heat up locally to complete the welding action. Furthermore, the functional block 3312 can be replaced according to the shape of the welding area on the product B to be welded, thus adapting to different product welding needs. In a preferred embodiment, the functional block 3312 has a recessed mounting hole 43, into which a heating rod (not shown) is inserted and assembled. The heating rod serves as a heating element for heating the functional block 3312. In a preferred embodiment, the axial direction of the heating rod is parallel to the plane containing the welding functional surface 332, thus ensuring the temperature of the welding functional surface 332 is as uniform as possible.

[0041] In another embodiment, the welding body 331 can be a single piece, with the welding functional surface 332, inlet 41, outlet 42, and mounting hole 43 all directly formed on the welding body 331. In a preferred embodiment, the axial direction of the heating rod is parallel to the plane containing the welding functional surface 332, thus ensuring the temperature uniformity of the welding functional surface 332 as much as possible. In a modified embodiment, the mounting hole 43 and heating element may be omitted, with the welding body 331 itself serving as the heating element.

[0042] Please refer to the reference. Figures 2 to 13As shown, in a preferred embodiment of this application, the welding body 331 further includes a support block 3313. The support block 3313 and the mounting block 3311 are stacked along a third direction, and the functional block 3312 is positioned between the mounting block 3311 and the support block 3313 along a third direction. The welding functional surface 332 passes through the support block 3313 along a third direction and protrudes from the support block 3313. In a preferred embodiment, the functional block 3312 is fixedly positioned within a fixing groove (3001, 3002) formed on the mating surfaces of the support block 3313 and the mounting block 3311. A portion 3001 of the fixing groove is formed on the support block 3313, and another portion 3002 of the fixing groove is formed on the mounting block 3311. The welding functional surface 332 of the functional block 3312 passes downward through the support block 3313 along a third direction and protrudes from the lower surface of the support block 3313.

[0043] Please refer to the reference. Figure 2 and Figure 13 As shown in the embodiment of this application, four functional blocks 3312 are provided on the same support block 3313. The four functional blocks 3312 are spaced apart along a transverse direction perpendicular to the third direction. Two functional blocks 3312 correspond to one product B to be welded. In the preferred embodiment of this application, the welding functional surface 332 of the functional block 3312 passes downward through the support block 3313 along the third direction and protrudes from the lower surface of the support block 3313 to form a boss-like structure. The purpose is to make the welding functional surface 332 make more stable and reliable contact with the welding area on the product B to be welded, and to make the heating and welding position more accurate and controllable. Of course, in order to ensure the overall stability of the product B to be welded, the lower surface of the support block 3313 also protrudes downward along the third direction to form a transition rib 333. The two ends of the transition rib 333 are adjacent to the welding functional surfaces 332 of at least two functional blocks 3312 located on the same bearing block 3313, so that the two welding functional surfaces 332 are as flush as possible with the lower surface of the transition rib 333, so as to avoid the local downward pressure of the welding functional surfaces 332 on the product B to be welded, which would cause local deformation of the product B to be welded (the product B to be welded is generally a thin copper material, which is relatively soft and easy to deform). Please refer to the reference. Figures 2 to 13As shown, the bearing surface 21 is provided with limiting members 22 on both sides along the first direction at the corresponding welding position, and an elastic push rod assembly (not labeled) is formed on one side of the limiting member 22. The elastic push rod assembly includes a push rod body 23 and an elastic body (not shown). The elastic body elastically pushes the push rod body 23 along the first direction, causing the push rod body 23 to press against one side of the carrier A located at the corresponding welding position, so that the carrier A can stay in a relatively accurate welding position. For better results, a limiting protrusion 231 is formed on the push rod body 23 along the first direction, and a groove A1 is formed on the side of the carrier A. When the carrier A moves from the waiting position to the welding position along the second direction, the protrusion 2311 scrapes and slides on the side of the carrier A and finally engages with the groove A1 for limiting. The push rod body 23 is restricted to the welding position by the two limiting members 22 located on both sides along the second direction.

[0044] Please refer to the reference. Figures 10 to 13 As shown, along a third direction, the heating element of the illustrated embodiment of this application is disposed at the midpoint between the liquid cooling channel (liquid cooling assembly) and the welding functional surface 332. This design aims to achieve rapid heating of the welding functional surface 332 while simultaneously rapidly cooling the heating element, thereby improving welding efficiency.

[0045] The following describes a welding method for welding product B using the automatic welding equipment of this application. This welding method includes at least the following steps: S1. Place the carriers A carrying the products B to be welded one by one on the conveying surface 11 of the conveying module 1, and the conveying module 1 conveys the carriers A on it along the first direction.

[0046] S2. Drive the stop pawl 311 to move downward along a third direction and stop one of the carriers A in the waiting position. This step is automatically controlled by the main control unit of the equipment.

[0047] S3. Drive the pusher claw 321 to move along the second direction and push the carrier A, which is in the position to be rotated in step S2, to the welding position. This step is automatically controlled by the main control unit of the equipment.

[0048] S4. Drive the welding body 331 to move downward along the third direction, and press the welding functional surface 332 onto the product B to be welded, which is located on the carrier A and pushed in step S3. The welding body 331 heats the product B to be welded through the welding functional surface 332 to perform contact heating welding. This step is automatically controlled by the main control unit of the equipment.

[0049] S5. After step S4 is completed, coolant is delivered through the liquid cooling component and flows through the liquid cooling channel to cool the welding body 331. The coolant is then transferred to the product B to be welded through the welding functional surface 332 to cool the product B to be welded. This step is automatically controlled by the main control unit of the equipment.

[0050] S6. Drive the welding body 331 to move upward along the third direction back to its original position. This step is automatically controlled by the main control unit of the equipment.

[0051] In a preferred embodiment of this application, the stop pawl 311 does not contact the conveying surface 11 during its entire stroke along the third direction, and the pusher pawl 321 does not contact the conveying surface 11 during its entire stroke along the second direction. This is to reduce unnecessary scraping of the conveying surface 11, ensuring the stability of the carrier A's position and preventing the positioning of the carrier A from being affected by scraping of the stop pawl 311 and pusher pawl 321 during the conveying motion of the conveying surface 11.

[0052] In a preferred embodiment of this application, each welding module 3 further includes a sensing component 8 (which may be such as a laser sensor or an infrared distance sensor, etc.), the sensing component 8 being disposed on the side of the conveying module 1 away from the bearing surface 21 along the second direction. Before executing step S2, step S20 may also be included: detecting, via the sensing component 8, whether there is a carrier A conveyed via the conveying surface 11 at the corresponding position; if there is a carrier A, then step S2 is executed.

[0053] In a preferred embodiment of this application, multiple welding modules 3 are arranged along a first direction on the automatic welding equipment. After executing step S1, the main control unit of the equipment prioritizes driving the first stop claw 311 located at the end of the conveying direction of the conveying surface 11 in the first direction to execute step S2; then it drives the second stop claw 311 adjacent to the first stop claw 311 in the opposite direction of the conveying direction of the conveying surface 11 to execute step S2; and so on, until the last stop claw 311 located at the beginning of the conveying direction of the conveying surface 11 is driven to execute step S2. In a preferred embodiment, when multiple stop claws 311 execute step S2, the stop claw 311 closer to the end of the conveying direction of the conveying surface 11 is always executed first, and the execution of step S2 of the second stop claw 311 is performed only after the first stop claw 311 has completed its execution of step S2.

[0054] Furthermore, before executing step S2, the main control unit of the equipment must first identify whether the welding component 33 corresponding to the stop claw 311 has completed the welding action. If it has been completed, the corresponding stop claw 311 can execute step S2. In a preferred embodiment, the automatic welding equipment of this application also includes a return conveyor module (not shown), which is parallel to the welding platform 2 along the second direction and located on the other side of the conveyor module 1. The return conveyor module forms a return conveyor surface (not shown) that is adjacent to and parallel to the bearing surface 21, and the conveying direction of the return conveyor surface is opposite to that of the conveyor surface 11. After executing the above steps S5 and S6, the welded carrier A located at the welding position is pushed out to the return conveyor surface of the return conveyor module by another carrier A newly pushed to the welding position along the second direction by the pusher claw (321), and rotated back to the starting position of the conveyor surface 11 via the return conveyor surface. Finally, the welded product is taken out manually or by a robot and put back into the welding product B. In a preferred embodiment, the conveyor module 1 and the return conveyor module can be designed as a closed circular production line.

[0055] The automated welding equipment and method described in this application enable precise welding of the welding positions on the product B to be welded. After welding, the welding positions on the product B can be rapidly cooled by a liquid cooling module (the liquid cooling components and liquid cooling channels described above), improving the overall efficiency of the welding process and saving energy. It also eliminates the need to place the entire product B, along with the carrier A, into a reflow oven for overall heating and welding. Furthermore, it eliminates the need for bolting the carrier A to secure the product B, as required in existing technologies, thus saving labor costs.
